Reason is the scheduling resource and unit of the to be removed cpus needs to be split in order to remove the cpu from its cpupool and move it to the idle scheduler. In case one of the involved cpus happens to have received a sched slave event due to a vcpu former having been running on that cpu being woken up again, it can happen that this cpu will enter sched_wait_rendezvous_in() while its scheduling resource is just about to be split. It might wait for ever for the other sibling to join, which will never happen due to the resources already being modified. This can easily be avoided by: - resetting the rendezvous counters of the idle unit which is kept - checking for a new scheduling resource in sched_wait_rendezvous_in() after reacquiring the scheduling lock and resetting the counters in that case without scheduling another vcpu Reported-by: Igor Druzhinin Signed-off-by: Juergen Gross --- xen/common/sched/core.c | 21 +++++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-) diff --git a/xen/common/sched/core.c b/xen/common/sched/core.c index 7e8e7d2c39..d95f30e395 100644 --- a/xen/common/sched/core.c +++ b/xen/common/sched/core.c @@ -2415,7 +2415,8 @@ static struct sched_unit *sched_wait_rendezvous_in(struct sched_unit *prev, { struct sched_unit *next; struct vcpu *v; - unsigned int gran = get_sched_res(cpu)->granularity; + struct sched_resource *sr = get_sched_res(cpu); + unsigned int gran = sr->granularity; if ( !--prev->rendezvous_in_cnt ) { @@ -2482,6 +2483,19 @@ static struct sched_unit *sched_wait_rendezvous_in(struct sched_unit *prev, atomic_set(&prev->next_task->rendezvous_out_cnt, 0); prev->rendezvous_in_cnt = 0; } + + /* + * Check for scheduling resourced switched.

Ah, okay, then I believe a combination of the two patches is needed. Something like the attached version?

As stop_machine_run() is using tasklets this requires scheduling of idle vcpus on all cpus imposing the need to call rcu_barrier() on idle cpus only in case of core scheduling being active, as otherwise a scheduling deadlock would occur. There is no need at all to do the syncing of the cpus in tasklets, as rcu activity is started in __do_softirq() called whenever softirq activity is allowed. So rcu_barrier() can easily be modified to use softirq for synchronization of the cpus no longer requiring any scheduling activity. As there already is a rcu softirq reuse that for the synchronization. Finally switch rcu_barrier() to return void as it now can never fail.

Reason is the scheduling resource and unit of the to be removed cpus needs to be split in order to remove the cpu from its cpupool and move it to the idle scheduler. In case one of the involved cpus happens to have received a sched slave event due to a vcpu former having been running on that cpu being woken up again, it can happen that this cpu will enter sched_wait_rendezvous_in() while its scheduling resource is just about to be split. It might wait for ever for the other sibling to join, which will never happen due to the resources already being modified. This can easily be avoided by: - resetting the rendezvous counters of the idle unit which is kept - checking for a new scheduling resource in sched_wait_rendezvous_in() after reacquiring the scheduling lock and resetting the counters in that case without scheduling another vcpu Reported-by: Igor Druzhinin Signed-off-by: Juergen Gross --- xen/common/sched/core.c | 27 +++++++++++++++++++++++++-- 1 file changed, 25 insertions(+), 2 deletions(-) diff --git a/xen/common/sched/core.c b/xen/common/sched/core.c index 7e8e7d2c39..11a9589945 100644 --- a/xen/common/sched/core.c +++ b/xen/common/sched/core.c @@ -2415,7 +2415,8 @@ static struct sched_unit *sched_wait_rendezvous_in(struct sched_unit *prev, { struct sched_unit *next; struct vcpu *v; - unsigned int gran = get_sched_res(cpu)->granularity; + struct sched_resource *sr = get_sched_res(cpu); + unsigned int gran = sr->granularity; if ( !--prev->rendezvous_in_cnt ) { @@ -2482,6 +2483,19 @@ static struct sched_unit *sched_wait_rendezvous_in(struct sched_unit *prev, atomic_set(&prev->next_task->rendezvous_out_cnt, 0); prev->rendezvous_in_cnt = 0; } + + /* + * Check for scheduling resourced switched.

As stop_machine_run() is using tasklets this requires scheduling of idle vcpus on all cpus imposing the need to call rcu_barrier() on idle cpus only in case of core scheduling being active, as otherwise a scheduling deadlock would occur. There is no need at all to do the syncing of the cpus in tasklets, as rcu activity is started in __do_softirq() called whenever softirq activity is allowed. So rcu_barrier() can easily be modified to use softirq for synchronization of the cpus no longer requiring any scheduling activity. As there already is a rcu softirq reuse that for the synchronization. Remove the barrier element from struct rcu_data as it isn't used. Finally switch rcu_barrier() to return void as it now can never fail.

I see why one may want for something like that to be in the first branch of the if{}... I was just saying that I personally like it better for something like this to be close to where the pointer is dereferenced...

I agree it's not great to have loads of little helper programs lying around. But it's a lot better than pulling in a full perl installation for a single line. I sort of feel like part of the issue is that this is written in shell at all. The necessity to fall back to perl seems to me to indicate that bash is the wrong language for what needs to happen here.

Maybe it would be better to use stat(1) ?=C2=A0 On Linux
=C2=A0 =C2=A0stat -L -c%D.%i /dev/stdin blah.lock
or some such, and then compare the two numbers.

I'm reluctant to host a general-purpose shell utility in xen.git, no matter how useful...

Change that handling by setting opt_ept_ad to 0 for this cpu type explicitly if no user value has been set.

Surely new Xen can't be given any pages in use > _in any way_ by old Xen, no matter whether it's ones assigned to > domains, or ones used internally to (old) Xen. Old and new Xen do not coexist. There is a kexec (via kexec_reloc.S and purgatory) from old to new. There are some pages which new Xen MUST NOT scribble on, because they actually belong to the domains being preserved. That includes the EPT (or at least IOMMU) page tables. I suppose new Xen also mustn't scribble on the pages in which old Xen has placed the migration information for those domains either. At least, not until it's consumed the data. Anything else, however, is fine for new Xen to scribble on. Fairly much anything that the old Xen had allocated from its xenheap (and not subsequently shared to a guest, qv) is no longer required and can be treated as free memory by the new Xen, which now owns the machine. --=-KyIG46U/YpOjb09Xv8nX Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64

Hm, I'm not sure my previous response actually answered your question; sorry, I've been away all week so it's still Monday morning in my head right now. Let me try again... What I said just now is true. The new Xen can use anything that isn't actually owned by domains, but old Xen is dead and any of its own internal allocations, Xen page tables and data structures (i.e. most of what it allocated on its xenheap) have died with it and those pages are considered 'free' by the new Xen. Theoretically, it would be possible for the new Xen to go directly to that state. The live update data could be processed *early* in the new Xen before the boot allocator is even running, and new Xen could prime its boot allocator with the memory ranges that happen to be available according to the criteria outlined above. Our initial implementation did that, in fact. It was complex in early boot, and it didn't scale to more than 512 separate free ranges because the boot allocator panics if it has more free regions than that. That's why we settled on the model of reserving a specific region for the new Xen to use for its boot allocator. Old Xen promises that it won't put anything into that region that needs to be preserved over kexec, and then the startup process for the new Xen is much simpler; it can use that contiguous region for its boot allocations and then process the live update data in a better environment once things like vmap() are already available Then *finally* it can add the rest of the system memory that *isn't* used by running domains, into the buddy allocator. So this requires old Xen to promise that it *won't* put anything into that region of reserved bootmem (aka "those pages"), that needs to be preserved across kexec. That promise is *mostly* equivalent to "will only allocate xenheap pages from those pages"... except for the fact that sometimes we allocate a page from the xenheap and share it to domains. Thus, "don't do that then", and THEN we can say that it's OK for xenheap allocations to come from the reserved bootmem region, but not domheap allocations. --=-+8toAofbnn5Tp+fGw2zO Content-Type:

Right. The solution there is two-fold: For pages in the general population (outside the reserved bootmem), the responsibility lies with the new Xen. As it processes the live update information that it receives from the old Xen, it must mark those pages as in-use so that it doesn't attempt to allocate them. That's what this bugfix paves the way for =E2=80=94 it avoids putting *bad* pages into the buddy allocator, by setting the page state before the page is seen by init_heap_pages(), and making init_heap_pages() skip the pages marked as broken. It's trivial, then, to make init_heap_pages() *also* skip pages which get marked as "already in use" when we process the live update data. The second part, as discussed, is that the old Xen must not put any of those "needs to be preserved" pages into the reserved bootmem region. That's what Paul is working on. We stop sharing xenheap pages to domains, which is part of it =E2=80=94 but *also* we need to use the right allocation for any IOMMU page tables and IRQ remapping tables which need to be preserved, etc.=20 That partly comes out of Hongyan's secret hiding work anyway, since we no longer get to assume that xenheap pages are already mapped *anyway*, so we might as *well* be allocating those from domheap. --=-s1n9oXDt5fy2N8yIY9z3 Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64

I just outlined the two-part nature of the issue. First the old Xen must ensure *not* to put any pages that need to be preserved, in the reserved region. You're talking about the second part, where the new Xen has to work out what pages in the *rest* of memory are available to it and which it needs to preserve. Which means my first answer has to be "hell no, you can't even *talk* about the page_info here". Because what we pass from Xen#1 to Xen#2 has to be an *ABI*, with clearly defined forward-compatible structures. Never passing over Xen-internal structs like the page_info. So yes, the new Xen has to infer it from the migration structures for the domains, and mark the appropriate pages as 'in use' before init_heap_pages() gets to look at them. But bear in mind that we can *define* the structures we use for this too, based on top of the existing live migration data structures. We don't want to have to actually walk the hardware page tables in the new Xen. We'll probably end up passing over a list of pages, from old Xen to new in a newly-defined record type. And old Xen would just keep that list as it allocates pages for those page tables. Much as it keeps the page list for domains. --=-VNzSlpnl7TfW2izxqusw Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"

At the moment I just *don't* use the pages in the reserved region (and that includes inittext/initdata freed by Xen, since the plan is for new Xen to be placed where old Xen used to be in physical memory). From https://xenbits.xen.org/gitweb/?p=3Dpeople/dwmw2/xen.git;a=3Dcommitdiff;h= =3Dcdbef644824 void init_lu_reserved_pages(paddr_t ps, paddr_t pe) { if (!lu_bootmem_start) init_xenheap_pages(ps, pe); /* There is ongoing work for other reasons to eliminate the use of * share_xen_page_with_guest() and get to a point where the normal * xenheap actually meets the requirement we need for live update * reserved memory, that nothing allocated from it will be mapped * to a guest and/or need to be preserved over a live update. * Until then, we simply don't use these pages after boot. */ } > And of course this means you're intending to (at least > partially) resurrect the distinction between domheap and xenheap, > which isn't said anywhere in Paul's series, I don't think. Right. Secret hiding makes the distinction (xenheap is mapped, domheap is not) mostly go away. We are talking about restoring *a* distinction between one type of page (Xen ephemeral pages which don't need to be preserved over live update) and another (must be preserved), but whether that should still be called "xenheap" vs. "domheap", despite the massive parallels, isn't entirely clear. > If this > is a sufficiently correct understanding of mine, then on one hand > I start seeing the point of the conversion Paul wants to make, but > otoh this then feels a little like making the 2nd step before the > 1st.

In terms of the design discussion for live update, I don't know that "xenheap" and "domheap" are the right terms to use as they have a loaded existing meaning (albeit one which is being blurred a lot as the secret hiding happens). Let's say "ephemeral pages" and "preserved pages". If Xen needs to allocate a page which needs to be preserved over live update, then it can only come from *outside* the reserved bootmem region. If Xen needs to allocate an ephemeral page (which can be thrown away on live update), that can come from *anywhere*. But we might *start* by looking in the reserved region, and then allocate from the general population of memory after the reserved region has been used up. Obviously, the *usage* of this maps fairly closely to the existing xenheap and domheap. But we wouldn't end up with a hard partition between 'xenheap' and 'domheap' as we have had on some architectures before. We'd satisfy xenheap allocations *first* from the xenheap-only reserved ranges, and then from the rest of memory (domheap). --=-6uow76bJznT872up2Dmr Content-Type: application/x-pkcs7-signature;

Paul's opinion seemed to be that with secret hiding coming along and destroying the "xenheap is mapped anyway" assumption, the benefit of allocating a xenheap page and then mapping it to a guest is basically gone *anyway*, so that part at least made a viable cleanup regardless of the overall direction. By the time we start making the IOMMU use domheap for *its* page table allocations because we want 'domheap =E2=89=A1 preserved pages', yes I completely agree that we should have settled the overall direction and nomenclature first. But I'm inclined to agree with Paul that this part stands by itself as a cleanup regardless of that. --=-fX1GF6gupowYAz/fE0K0 Content-Type: application/x-pkcs7-signature; name="smime.p7s"

this. I've been able to do some analysis of the situation. Basically, on the server I'm using, I do not see stalls severe enough to cause=20 NMI/watchdogs to fire, but I do see, during boot, some preliminary signs of that. I checked what was happening in Xen at that point in time ('r' debug- key, which dumps the scheduler's data scructures), and I found out that there is a vCPU kind of stuck in a runqueue. In fact, the vCPU is in there, i.e., it is ready to run *but* not running, despite being plenty of idle pCPUs that could possibly run it. Reason why it's not being picked up, is that its credit are less than the ones of the idle vCPU. I have a theory about how it got in such a situation and, if I'm right, a draft of an idea of how to fix this. We're using this bug, that Glen kindly created, to track this issue: https://bugzilla.opensuse.org/show_bug.cgi?id=3D1165206#c3 But of course I'll keep upstream MLs updated as well. Stay tuned. :-) --=20 Dario Faggioli, Ph.D http://about.me/dario.faggioli Virtualization Software Engineer SUSE Labs, SUSE https://www.suse.com/ ------------------------------------------------------------------- <> (Raistlin Majere) --=-6JTCmd6+lU+GHqnqXqV3 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEES5ssOj3Vhr0WPnOLFkJ4iaW4c+4FAl5iVf8ACgkQFkJ4iaW4 c+7x8Q//agxkApjy3KhJLyiCoOf0Ll6RYPCxYAark/R2zEjpCXZ/QNRqlLyegvWv jeoWTd1wXnApwMrfmz1uMWgWvOWGi0jWy2BpH7H9nOctzkL4HX2Ygl01JA5VC2QO Uw+NLnPCF9oAz/1aIMt+M8KLE2T3fplnYR7xNado9ZbKt6qlQn3ydDIJKHZ21OFc TUfViu/hl1TQGPlNPU4MOZWF962Vg0uIZSoQUxX5sdIAtjcp7rXLLFl1jduf9191 m3P3p0kNEfVc4DIqCKw0o656aOIIeOAyYRH5CXFd4vyenP97O4gcvWGFUauIJNHz oe6pFIeteapWhkyfzNPyCYNcJcMkZnOVsCixCTrX2+TTScP6OS+J1LBcWfwfoQ0i rJ2mMlDXrw/mk8o6X8s41LU++pn4lUhZgZiSJJ0zs7Dz8dg5BIZU6NpkqsYTNhTY hrzIZYTyl8ew9h5gARNpxN03S10tGUP3AtbbpHgbeppCAX3mmOCn1x9llugu+XxX 4NR2ep3i0RvGw4PebwycEPaSkdbXveZDedTS4tzJUUxNs+QZkTd/80V7WcrkXUU6 XtRFUk8yNirDB9VlBsjZF7ZJkYNxmjhDMfIos9sgpHMvlXSYyfIk3zBmgTVKjzIk c8sH5yBUZSeSyTO3GshruSx/LcW1g6V3o//hB3hKjCMx4CD2eQo= =l2V8 -----END PGP SIGNATURE----- --=-6JTCmd6+lU+GHqnqXqV3-- --===============2876515829170176108== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KWGVuLWRldmVs IG1haWxpbmcgbGlzdApYZW4tZGV2ZWxAbGlzdHMueGVucHJvamVjdC5vcmcKaHR0cHM6Ly9saXN0 cy54ZW5wcm9qZWN0Lm9yZy9tYWlsbWFuL2xpc3RpbmZvL3hlbi1kZXZlbA== --===============2876515829170176108==-- From xen-devel-bounces@lists.xenproject.org Fri Mar 06 13:58:05 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Fri, 06 Mar 2020 13:58:05 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jADUF-0007aS-QF; Fri, 06 Mar 2020 13:57:59 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jADUE-0007aM-53 for xen-devel@lists.xenproject.org; Fri, 06 Mar 2020 13:57:58 +0000 X-Inumbo-ID: 7b8c485c-5fb2-11ea-b74d-bc764e2007e4 Received: from mail-ed1-x543.google.com (unknown [2a00:1450:4864:20::543]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 7b8c485c-5fb2-11ea-b74d-bc764e2007e4; Fri, 06 Mar 2020 13:57:57 +0000 (UTC) Received: by mail-ed1-x543.google.com with SMTP id cq8so2635141edb.2 for ; Fri, 06 Mar 2020 05:57:57 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=from:to:cc:references:in-reply-to:subject:date:message-id :mime-version:content-transfer-encoding:thread-index :content-language; bh=NNoHPMYXivhg8cxAwF13S1d4kdAQP7DbXxhhdXqeSH4=; b=pck0Wi3aBedORbmjXM9NhMlWaXlsCBRFmpsA647U3rfhZxydD0wTsA0mlH9/jROnfg E2VSIRpZBKG0SFzGztFoUcbCPHgQIknQiTxpoZJ1gNPTJo0e1mc3AY47yn8508ZNf0Ae k7oEBjJVk7h1kJU0rAmXuTsnlDBjP53bhRwq8iXT3RY1JiXRoTHjA8HtH3yxFizu3GH4 0liTEKJGL5cW8a3yhpH2KILiPJ7kKnuzCxS4pbUUE6BivJsiUQxT97sXYsdqA03/Wy39 hvd0szQs0qbuY+5zVmp20phcJk76qJfhNzlRrUQR0teLp53j53mgWTqq4AfDKFrZH/vs AoVw== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:from:to:cc:references:in-reply-to:subject:date :message-id:mime-version:content-transfer-encoding:thread-index :content-language; bh=NNoHPMYXivhg8cxAwF13S1d4kdAQP7DbXxhhdXqeSH4=; b=q6jQuNJCQFVoW/VMKtbNZoSLEP4zah7GB0ElLb19YLSHycE83cHmWPkgzXISvS5ei5 /T5UNW0sfbuBYd3+5M5mkVK1ufKn8EPakt3oYLXiNThg2rpxBcldsycuiTUG18aIIdtn QMfDcKf7+GrGbjAdmSPQ5EUbJ/QB9L8QsvjQLOgpbDCTdJHo32EpLdKFP92FHp821o2K 9BQDQYXSBcOHDd8JJDu7MmgagNbAoOSRWqEejOlIeZMxOabGglc7LeykPFNWFjY0+xtf /Q+jUwEanxlmv1sA4qKIaMVO0+0mqNW5dVzjlo9d5UUh/GXgte9Plk2mQnMlkcoLjHvD RumA== X-Gm-Message-State: ANhLgQ2cU4EUTbIXKaEGLOLyQcNbMFiUkCxJ95gKE/roZ0DkGRnww7gZ hcx3c2xpBuX4PPEyMeviySo= X-Google-Smtp-Source: ADFU+vvYwAsH+s6UGF5eV8tVYsbE0ZyIzGEegQnmdmx2z9iKeNM0xD6wZJmhy8UhrDUti3XJ8OgzNw== X-Received: by 2002:a05:6402:95b:: with SMTP id h27mr3213313edz.114.1583503076685; Fri, 06 Mar 2020 05:57:56 -0800 (PST) Received: from CBGR90WXYV0 (54-240-197-235.amazon.com.

"Xen-devel" --=separator Content-Type: text/plain; charset="utf-8" Content-Disposition: inline Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Xen Security Advisory CVE-2020-0551 / XSA-315 Load Value Injection (LVI) speculative side channel ISSUE DESCRIPTION ================= This is very closely related to the Microarchitectural Data Sampling vulnerabilities from May 2019. Please see https://xenbits.xen.org/xsa/advisory-297.html for details about MDS. A new way of using the micro-architectural details behind MDS has been identified. Instead of simply trying to sample data from a different privilege context, an attacker can arrange for poisoned data to be consumed (speculatively) in a victim context. This expands the range of tools by which an attacker can manipulate speculation in the victim context to leak data via a side channel. For more details, see: https://software.intel.com/security-software-guidance/insights/deep-dive-load-value-injection IMPACT ====== An attacker, which could include a malicious untrusted user process on a trusted guest, or an untrusted guest, can potentially cause a victim context (process, or guest, or guest kernel, or hypervisor) to leak secrets available to it. VULNERABLE SYSTEMS ================== Systems running all versions of Xen are affected. Only x86 processors are vulnerable. ARM processors are not believed to be vulnerable. Only Intel based processors are potentially affected. Processors from other manufacturers (e.g. AMD) are not believed to be vulnerable. Please consult the Intel Security Advisory for details on the affected processors. MITIGATION ========== Xen does not support the use of SGX (Software Guard Extensions). Outside of the SGX enclave case, the attacker has a limited ability to control the paging behaviour in the victim context. Therefore, it is not believed that there is a practical way to attack a victim context which is not an SGX enclave. Furthermore, preexisting work (including fixes for MDS, SMAP hardening for user pointers) and in-progress work (core scheduling for SMT systems) all raise the bar further for an attacker. There are no known LVI gadgets within Xen. As a result, we have decided not to make any changes to default configurations of Xen. Systems with untrusted PV guests, and whose host administrators are worried about potential LVI gadgets, might wish to consider changing the VM to be HVM instead, or make use of PV-Shim, to limit the scope of a potential attack. NOTE REGARDING PAGE MODIFICATION LOGGING ======================================== Included for completeness, rather than due to being a realistic concern: On Intel Broadwell and later systems, Xen uses Page Modification Logging to accelerate logdirty tracking on migration. The use of this does put the guest kernel at a higher risk of being attacked, due to the use of EPT Access/Dirty bits used behind the scenes. Userspace shouldn't be able to influence when a migration occurs, but booting Xen with `ept=no-ad` will mitigate this concern by causing Xen to fall back to software logdirty tracking. RESOLUTION ========== There is no complete resolution available. In general, administrators of Xen systems are recommended to take no action in response to this vulnerability. If potential LVI gadgets are discovered in Xen, they will be addressed on a case by case basis, in the same way as Spectre v1 hardening. NOTE REGARDING LACK OF EMBARGO ============================== Despite an attempt to organise predisclosure, the discoverers ultimately did not authorise a predisclosure. -----BEGIN PGP SIGNATURE-----

That's what this paragraph above, plus similar ones in the cover letter ,were supposed to mean. If it is not clear enough, sorry. > Everything reported to xen-devel appears to suggests it is a credit2 > problem. It doesn't manifest on versions of Xen before credit2 > became > the default, and switching back to credit1 appears to mitigate the > problem. >=20 Yes, because even if the issue is there in both cases, when you use Credit2 it manifests as vCPUs being starved (because of the "they end up having less priority than the idle vCPU" thing). When you use Credit1, this does not happen, because time accounting and prioritization are done differently there. Switching to Credit1, at least on the box where I could reproduce the problem, did not make the issue that the vCPUs run for way too long disappear. It's the symptoms that this issue cause that are different for the two schedulers. > Certainly as far as XenServer is concerned, we haven't seen symptoms > like this in a decade of running credit1. >=20 I am only able to reproduce this issue on one box, and not really 100% deterministically. I have never noticed anything like this in the past few years, on Credit2. At least, nothing as severe as this (or we would have noticed, which is what, in fact, has happened!). With Credit1, even if the issue is there, you won't notice it in this form, se we really can't know.

Under many respects, Credit1 is basically a slightly more powerful variant of Round-Robin. The actual time vCPUs spend executing influences the scheduling decisions a lot less than in Credit2 (well, it influences the scheduling decisions a lot less than in any scheduler of any OS or hypervisor conceived and implemented in the last decade, or maybe even more). As a matter of fact, this property happens to have shield it from the nastiest effects of the issue at hand. > What Dario is saying (if I understand him correctly) is that the > *proximate* cause

exactly what I meant. :-) Regards --=20 Dario Faggioli, Ph.D http://about.me/dario.faggioli Virtualization Software Engineer SUSE Labs, SUSE https://www.suse.com/

Looking > at e.g. runq_insert() I'm getting the impression it's not. >=20 In Credit2, we don't have the idle vCPUs in the runqueue. So we will never compare non-idle with idle while inserting. But this is a good point, in general, and I think we may need to turn the ">" in a ">=3D" in runq_candidate(). > Looking at t2c_update() I'm also getting the impression that > there's UB when the subtraction underflows. After all, if > -1 << 30 wasn't small enough a value, I don't see why -1 << 31 > would be. >=20 Mmm... not sure I am getting. Are you suggesting we should apply a cap to val? If yes, this looks like an issue independent from what the value of CSCHED2_IDLE_CREDIT is, but yeah, we can do that. Or am I missing something?

FWIW, this is way it took me a while to get to the bottom of this. I was assuming it was *entirely* a Credit2 specific issue (caused by, e.g., something like I found and fixed with patch 2). When I noticed that things were not exactly like that, I also realized that we at least need to prevent --under any circumstance-- that idle vCPUs are preferred over "regular" vCPUs, and even if I did consider approaches like "compacting" the credits dynamic, I went straight for the INT_MIN approach. Considering how this thread is going, I guess we should actually push this further, and limit the "credit swing".

5 13:49:09 2020 +0100 x86/vvmx: fix virtual interrupt injection when Ack on exit control is used When doing a virtual vmexit (ie: a vmexit handled by the L1 VMM) interrupts shouldn't be injected using the virtual interrupt delivery mechanism unless the Ack on exit vmexit control bit isn't set in the nested vmcs. Gate the call to nvmx_update_apicv helper on whether the nested vmcs has the Ack on exit bit set in the vmexit control field.

Gate the call to nvmx_update_apicv helper on whether the nested vmcs has the Ack on exit bit set in the vmexit control field. Note that this fixes the usage of x2APIC by the L1 VMM, at least when the L1 VMM is Xen. Signed-off-by: Roger Pau Monné Reviewed-by: Kevin Tian dot: graph is too large for cairo-renderer bitmaps.

It did not work, because than the hint is "bound" to the closest next call in the function which is cr4_init() in this case. The unwinder would not take it into account. In my case, I placed it at the beginning of cpu_bringup_and_idle(). I also open coded it and played with the offset in the orc entry, but that did not work for some other reason. However, now I tried this diff --git a/arch/x86/xen/smp_pv.c b/arch/x86/xen/smp_pv.c index 6b88cdcbef8f..39afd88309cb 100644 --- a/arch/x86/xen/smp_pv.c +++ b/arch/x86/xen/smp_pv.c @@ -92,6 +92,7 @@ asmlinkage __visible void cpu_bringup_and_idle(void) { cpu_bringup(); boot_init_stack_canary(); + asm volatile (UNWIND_HINT(ORC_REG_UNDEFINED, 0, ORC_TYPE_CALL, 1)); cpu_startup_entry(CPUHP_AP_ONLINE_IDLE); } and that seems to work. I need to properly verify and test, but the explanation is that as opposed to the above, cpu_startup_entry() is on the idle task's stack and the hint is then taken into account. The unwound stack seems to be complete, so it could indeed be the fix.

In the above context (plus the fact that the toolstack use /libxl to enumerate devices), I still think giving driver domain write access to the backend/ node is the right solution for this problem. --=20 Best Regards, Marek Marczykowski-G=C3=B3recki Invisible Things Lab A: Because it messes up the order in which people normally read text.

The unwound > stack seems to be complete, so it could indeed be the fix. Not the correct one though. Objtool rightfully complains with arch/x86/xen/smp_pv.o: warning: objtool: cpu_bringup_and_idle()+0x6a: undefined stack state and all the other hacks I tried ended up in the same dead alley. It seems to me the correct fix is that all orc entries for cpu_bringup_and_idle() should have "end" property set to 1, since it is the first function on the stack. I don't know how to achieve that without the assembly hack in the patch I sent. If I am not missing something, of course. Josh, any idea?

As such, and also because the code is a bit entangled with the x86 platform, even on ARM we are building and running qemu-system-i386 to get the PV disk and PV framebuffer. Of course, no x86 emulation is actually done. Ideally we would have a non-arch-specific machine type for the PV backends, but that doesn't exist today. In short, I think this patch is fine, at least until somebody comes around and tries to add emulation to Xen on ARM. > Signed-off-by: Philippe Mathieu-Daudé > --- > Cc: Stefano Stabellini > Cc:

I revamped this, taking into account your later suggestion of a helper that works on the count_info. Looks more like this: /* If it was already broken, it stays broken */ if ( pgc_is_broken(x) ) broken =3D 1; if ( pgc_is_offlined(x) || pgc_is(x, free) ) nx |=3D broken ?

But I am not going to push for it :). I'm generally sympathetic to that point of view but at this point, all those page states are kind of being redefined and it makes sense to think about them all; having them all change doesn't hurt.

Nah, that would be worse. This way there are two cases which are explicitly handled and the list to use for each of them is explicitly set. The 'if (a||b) =E2=80=A6 some_function(a ? thing_for_a : thing_for_= b)' construct is much less comprehensible. > > @@ -1699,14 +1714,14 @@ unsigned int online_page(mfn_t mfn, > > uint32_t *status) > > do { > > ret =3D *status =3D 0; > > =20 > > - if ( y & PGC_broken ) > > + if ( (y & PGC_state) =3D=3D PGC_state_broken || > > + (y & PGC_state) =3D=3D PGC_state_broken_offlining ) > > { > > ret =3D -EINVAL; > > *status =3D PG_ONLINE_FAILED |PG_ONLINE_BROKEN; > > break; > > } > > - > > - if ( (y & PGC_state) =3D=3D PGC_state_offlined ) > > + else if ( (y & PGC_state) =3D=3D PGC_state_offlined ) >=20 > I don't see a need for adding "else" here. They are mutually exclusive cases. It makes things a whole lot clearer to the reader to put the 'else' there, and sometimes helps a na=C3=AFve compiler along the way too. > > --- a/xen/include/asm-x86/mm.h > > +++ b/xen/include/asm-x86/mm.h > > @@ -67,18 +67,27 @@ > > /* 3-bit PAT/PCD/PWT cache-attribute hint. */ > > #define PGC_cacheattr_base PG_shift(6) > > #define PGC_cacheattr_mask PG_mask(7, 6) > > - /* Page is broken? */ > > -#define _PGC_broken PG_shift(7) > > -#define PGC_broken PG_mask(1, 7) > > - /* Mutually-exclusive page states: { inuse, offlining, offlined, > > free }. */ > > -#define PGC_state PG_mask(3, 9) > > -#define PGC_state_inuse PG_mask(0, 9) > > -#define PGC_state_offlining PG_mask(1, 9) > > -#define PGC_state_offlined PG_mask(2, 9) > > -#define PGC_state_free PG_mask(3, 9) > > -#define page_state_is(pg, st) (((pg)->count_info&PGC_state) =3D=3D > > PGC_state_##st) > > - > > - /* Count of references to this frame. */ > > + /* > > + * Mutually-exclusive page states: > > + * { inuse, offlining, offlined, free, broken_offlining, broken } > > + */ > > +#define PGC_state PG_mask(7, 9) > > +#define PGC_state_inuse PG_mask(0, 9) > > +#define PGC_state_offlining PG_mask(1, 9) > > +#define PGC_state_offlined PG_mask(2, 9) > > +#define PGC_state_free PG_mask(3, 9) > > +#define PGC_state_broken_offlining PG_mask(4, 9) >=20 > TBH I'd prefer PGC_state_offlining_broken, as it's not the > offlining which is broken, but a broken page is being > offlined.

That part I hadn't touched but sure, I'll add those while I'm touching it.

Yeah, I'll remove some of those. --=-79rZ5Xq0J3JVm3irRaK6 Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding:

Yes, I think it's feasible for the initramfs pages, which is assigned to dom0 from uninitialised pages, to later get freed and then they'll want scrubbing? There *is* a path into free_heap_pages() with the need_scrub argument set, and I'd have to *prove* that it can never happen in order to... I don't know... put a BUG() in that case instead of supporting it? Didn't seem like that was the thing I wanted to do. > > @@ -2301,10 +2316,11 @@ int assign_pages( > > for ( i =3D 0; i < (1 << order); i++ ) > > { > > ASSERT(page_get_owner(&pg[i]) =3D=3D NULL); > > - ASSERT(!pg[i].count_info); > > + ASSERT(pg[i].count_info =3D=3D PGC_state_inuse || > > + pg[i].count_info =3D=3D PGC_state_uninitialised); >=20 > Same question here: Can uninitialized pages make it here?

You seem to have dropped the ASSERT immediately before the code snippet you cited, in which arbitrary other contents of count_info are not permitted. I put it back, in its current form after I rebase on top of Paul's commit c793d13944b45d assing PGC_extra. > > --- a/xen/include/asm-x86/mm.h > > +++ b/xen/include/asm-x86/mm.h > > @@ -72,12 +72,13 @@ > > * { inuse, offlining, offlined, free, broken_offlining, broken } > > */ > > #define PGC_state PG_mask(7, 9) > > -#define PGC_state_inuse PG_mask(0, 9) > > +#define PGC_state_uninitialised PG_mask(0, 9) > > #define PGC_state_offlining PG_mask(1, 9) > > #define PGC_state_offlined PG_mask(2, 9) > > #define PGC_state_free PG_mask(3, 9) > > #define PGC_state_broken_offlining PG_mask(4, 9) > > #define PGC_state_broken PG_mask(5, 9) > > +#define PGC_state_inuse PG_mask(6, 9) >=20 > Would imo be nice if this most common state was actually > either 1 or 7, for easy recognition.

The important one is that uninitialised has to be zero, since that's the default (because that's what the frame table is memset to. Which is changeable, but non-trivially so). --=-73LR1sUt+Bfb/TvTmdXw Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"

This makes it easier for later live update patches to make it conditional, since in live update we'll already have an existing dom0 being brought over from the previous Xen. But it's a cleanup in its own right in the meantime.

Replace it with something simpler that makes it somewhat clearer that the check for initrdidx < mbi->mods_count is because larger values are what find_first_bit() will return when it doesn't find anything. Also drop the explicit check for module #0 since that would be the dom0 kernel and the corresponding bit is always clear in module_map.

Shift it into a separate function and simplify __start_xen() a little bit. This is a cleanup in its own right, but will be even more desireable when live update provides an alternative path through __start_xen() that doesn't involve creating a new dom0 at all. Move the calculation of the 'initrd' parameter for create_dom0() down past the cosmetic printk about NX support, because in the fullness of time the whole initrd and create_dom0() part will be under the same "not live update" conditional. And in the meantime it's just neater.

An ASSERT does protect release builds. If the rule is that you must never call assign_pages() with pages that have the other bits in count_info set, then the ASSERT helps to catch the cases where people introduce a bug and start doing precisely that, and the bug never *makes* it to release builds. What we're debating here is the behaviour of assign_pages() when someone introduces such a bug and calls it with inappropriate pages. Currently, the behaviour is that the other flags are silently cleared. I've seen no analysis that such clearing is correct or desirable. In fact, for the PGC_state bits I determined that it now is NOT correct, which is why I changed it. While I was at it, I let it preserve the other bits =E2=80=94 which, again, should never be set, and which would trigger the ASSERT in debug builds if it were to happen. But I'm not tied to that behaviour. It's still a "can never happen" case as far as I'm concerned. So let's make it look like this: for ( i =3D 0; i < (1 << order); i++ ) { ASSERT(page_get_owner(&pg[i]) =3D=3D NULL); /* * Note: Not using page_state_is() here. The ASSERT requires that * all other bits in count_info are zero, in addition to PGC_state * being appropriate. */ ASSERT((pg[i].count_info & ~PGC_extra) =3D=3D PGC_state_inuse || (pg[i].count_info & ~PGC_extra) =3D=3D PGC_state_uninitialis= ed); page_set_owner(&pg[i], d); smp_wmb(); /* Domain pointer must be visible before updating refcnt= . */ pg[i].count_info =3D (pg[i].count_info & PGC_state) | PGC_allocated= | 1; page_list_add_tail(&pg[i], &d->page_list); } OK? --=-EGMB5hbV+mcxudPxJr7E Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment;

In https://lists.xenproject.org/archives/html/xen-devel/2020-02/msg01664.html you indicated that you preferred for it to remain as-is but you did not even seem to be disputing that the code is simpler and easier for the reader to understand after my cleanup.

rather frequently get Xen crash on resume from S3. Full message below. This is Xen 4.13.0, with some patches, including "sched: fix resuming =66rom S3 with smt=3D0". Contrary to the previous issue, this one does not happen always - I would say in about 40% cases on this setup, but very rarely on physical setup. This is _without_ core scheduling enabled, and also with smt=3Doff. Do you think it would be any different on xen-unstable? I cat try, but it isn't trivial in this setup, so I'd ask first.

While I appreciate your insight, Jan, and your detailed reviews are undoubtedly helpful =E2=80=94 especially to me as I poke around the Xen code base without knowing where the bodies are buried =E2=80=94 I do someti= mes find that it degenerates into what appears to be gratuitous bikeshedding. Like *some* others, I'm perfectly capable of responding "I understand you would have done it differently, but I prefer it this way". But even for those like me who have the self-confidence (or arrogance?) to respond in such a way, the end result is often the same =E2=80=94 a patc= h series which the maintainer doesn't apply because it has "unresolved issues". Perfect is the enemy of good. Especially when perfection is so subjective. This definitely isn't the kind of welcoming community that I enjoy trying to get my junior engineers to contribute to. And they aren't snowflakes; they cope with the Linux community just fine, for the most part. Earlier today, I found myself adjusting a patch in order to tweak the behaviour of a "can never happen" situation, when it was far from clear that the *existing* behaviour in that situation would have been correct anyway. There is a lot of value in your reviews, and they are appreciated. But the overall effect is seen by some as making the Xen community somewhat dysfunctional.=20 The -MP makefile patch I posted yesterday... I almost didn't bother. And when I allowed myself to be talked into it, I was entirely unsurprised when a review came in basically asking me to prove a negative before the patch could proceed. So as far as I can tell, it'll fall by the wayside and the build will remain broken any time anyone removes or renames a header file. Because life's too short to invest the energy to make improvements like that. One of these days, I may attempt to revive my series cleaning up the 16-bit and 32-bit boot code. Which was a clear improvement and simplification, and again you gave extremely valid feedback which helped to improve it =E2=80=94 but again it was interspersed with more subjective and less helpful comments which basically derailed it.=20 Having carefully threaded my way through the existing byzantine code and made incremental bisectable changes, I ended up with feedback that basically would have required me to start again from scratch, in order to satisfy what appeared to be fairly arbitrary and subjective demands. As is often the case in creating a bisectable series out of complex changes, I had sometimes moved/refactored code, only to move/refactor it again in a subsequent patch. Sometimes the ordering of such inter- related changes can be fairly arbitrary, and I had made my choices as I'd progressed; the real focus being the end result. At one point you were picking on intermediate details of how I'd made my overall series bisectable, and seemed to be demanding that I go back and refactor (the intermediate stages for no better reason than because you would have done it differently.=20 Again, your attention to detail and your expertise are massively appreciated. But please let's remember that "perfect is the enemy of good", and strike a balance which allows forward progress without blocking improvements. Sometimes I wonder if you truly realise how much you derail the progress of a patch series just by raising well-intentioned "queries" around it. > > > > > --- a/xen/include/asm-x86/mm.h > > > > > +++ b/xen/include/asm-x86/mm.h > > > > > @@ -67,18 +67,27 @@ > > > > > /* 3-bit PAT/PCD/PWT cache-attribute hint. */ > > > > > #define PGC_cacheattr_base PG_shift(6) > > > > > #define PGC_cacheattr_mask PG_mask(7, 6) > > > > > - /* Page is broken? */ > > > > > -#define _PGC_broken PG_shift(7) > > > > > -#define PGC_broken PG_mask(1, 7) > > > > > - /* Mutually-exclusive page states: { inuse, offlining, offlined= , > > > > > free }. */ > > > > > -#define PGC_state PG_mask(3, 9) > > > > > -#define PGC_state_inuse PG_mask(0, 9) > > > > > -#define PGC_state_offlining PG_mask(1, 9) > > > > > -#define PGC_state_offlined PG_mask(2, 9) > > > > > -#define PGC_state_free PG_mask(3, 9) > > > > > -#define page_state_is(pg, st) (((pg)->count_info&PGC_state) =3D= =3D > > > > > PGC_state_##st) > > > > > - > > > > > - /* Count of references to this frame. */ > > > > > + /* > > > > > + * Mutually-exclusive page states: > > > > > + * { inuse, offlining, offlined, free, broken_offlining, broken= } > > > > > + */ > > > > > +#define PGC_state PG_mask(7, 9) > > > > > +#define PGC_state_inuse PG_mask(0, 9) > > > > > +#define PGC_state_offlining PG_mask(1, 9) > > > > > +#define PGC_state_offlined PG_mask(2, 9) > > > > > +#define PGC_state_free PG_mask(3, 9) > > > > > +#define PGC_state_broken_offlining PG_mask(4, 9) > > > >=20 > > > > TBH I'd prefer PGC_state_offlining_broken, as it's not the > > > > offlining which is broken, but a broken page is being > > > > offlined. > > >=20 > > > It is the page which is both broken and offlining. > > > Or indeed it is the page which is both offlining and broken. > >=20 > > I.e. you agree with flipping the two parts around? I hope I have respectfully made it clear that no, I'm really not happy with the very concept of such a request. Perhaps it would be easier for me to acquiesce, in the short term. But on the whole I think it's better to put my foot down and say 'no', and focus on real work and things that matter. > > > > > +#define page_is_offlining(pg) (page_state_is((pg),=20 > > > > > broken_offlining) || \ > > > > > + page_state_is((pg), offlinin= g)) > > > >=20 > > > > Overall I wonder whether the PGC_state_* ordering couldn't be > > > > adjusted such that at least some of these three won't need > > > > two comparisons (by masking off a bit before comparing). > > >=20 > > > The whole point in this exercise is that there isn't a whole bit for > > > these; they are each *two* states out of the possible 8. > >=20 > > Sure.

Yes, your code may be faster. But is it really worth it= =20 > compare to the cost of readability and futureproofness? No. Just no. If that kind of change is really a worthwhile win, it'll depend on the CPU. File a GCC PR with a test case as a missed optimisation. Don't make the source code gratuitously harder to read. Honestly, this, right here, is the *epitome* of why I, and others, sometimes feel that submitting a patch to Xen can be more effort than it's worth. This email is not intended as a personal attack; I hope you don't feel that it is. For about the fifth time: your careful reviews and your attention to detail are *massively* appreciated. Just a little over the time sometimes, and I'd like to ask you to take care to be aware of the overall effect, and that you are not blocking progress. Thanks. --=-MNlOcTSM62gD04oQNJax Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64

OK... I have attempted to address my frustration in a more coherent and hopefully productive way (qv), rather than resorting to monosyllabic responses. Apologies for that. Back to the specifics of this patch... GCC has had -MD support since so far back that I can't even find its origin in the git history. The SVN conversion seems kind of broken but I see signs of -MD having existed as far back as 1992. The -MP support, adding 'phony targets' for the headers listed in the -MD output, wasn't added until 2001: https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommitdiff;h=3Da5a4ce3c3c0ee It seems hardly surprising that the new behaviour was an additional option to GCC instead of retroactively changing the default which had already existed for around a decade. I do not think that questioning the (understandably conservative) default behaviour of GCC is appropriate or relevant in a review of a Xen patch such as this. As it happens, the GCC documentation at=20 https://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html#index-MP is slightly wrong. It refers to these as 'phony targets' but they aren't re= ally 'phony targets' in the sense referred to in make docs at https://www.gnu.org/software/make/manual/html_node/Phony-Targets.html because they aren't actually referenced from a .PHONY: rule. Neither are they "empty recipes", as described further in https://www.gnu.org/software/make/manual/html_node/Empty-Recipes.html because empty recipes, well, aren't actually empty. Those would perhaps more accurately be called "no-op recipes" because, like the example there containing a single semicolon, they do nothing. Both actual phony targets, and so-called empty recipes, do have the effect of overriding implicit and pattern rules for the target in question =E2=80=94 they could mess up auto-generated header files, for exam= ple. But what GCC -MP emits, despite its documentation, is neither of those things. It merely emits an empty rule with no recipe and no actual dependencies either. I don't think there's a specific term for that; it *isn't* a 'phony rule', as I said. It's probably best described as 'an explict rule without a recipe'.See=20 https://www.gnu.org/software/make/manual/html_node/Multiple-Rules.html where it states that 'If none of the explicit rules for a target has a recipe, then=20 make searches for an applicable implicit rule to find one see Using Implicit Rules).' So no, I don't think using -MP is going to break our handling of auto- generated header files, but we'd have known that from a trivial empirical build test within seconds, wouldn't we? Here's another cut down test case. You can experiment with turning it into a *real* 'phony rule', etc... $ grep ^ * foo.c:#include foo.c: foo.c:#include "foo.h" foo.c: foo.c:int main(void) foo.c:{ foo.c: printf(HELLO); foo.c: return 0; foo.c:} foo.h.orig:#define HELLO "Hello World!"

The make documentation at https://www.gnu.org/software/make/manual/html_node/Phony-Targets.html makes a distinction between "phony targets" and ".PHONY targets". What GCC emits *is* the former, while it is the latter which are documented as causing implicit rules to be skipped. So I think the GCC and Make documentation is entirely consistent, if somewhat suboptimal in its use of terms with different meanings which differ only in case and punctuation. Although looking back in retrospect, the difference between "phony target" and ".PHONY target" is clear enough that I wonder how I missed it. > Supposing you put all that in the commit message: > Acked-by: Ian Jackson > (for the original patch) To be honest, I don't think it lives there. It's just a digression, based on a half-misremembered idea that phony (not .PHONY) targets cause implicit rules to be skipped. Aside from that misremembrance, .PHONY rules aren't actually relevant to this commit in any way. It's two fairly pointless hours of my life that I want back, in which I could have been doing something more useful on extending our live update support to support inheriting the crashdump setup from the previous Xen, as I had planned to do today. Let's suppose I were to distil my 'research', including the above correction, into an assertion along the lines of "While make will skip implicit/pattern rules for targets which are=20 explicitly declared as .PHONY, what GCC emits with -MP are merely 'phony targets' which are rules without a recipe, and which don't cause implicit rules to be skipped. Thus, the presence of such a rule should not prevent auto-generated header files and the like from being created correctly." As we look back at this commit in future perhaps if we suspect it of doing something wrong, what *benefit* is there to seeing that in the commit comment? Assuming it's a correct assertion, it's fairly much going to be irrelevant to anyone who looks at this commit in future. And if it's false, and I'm wrong? It's going to be either a red herring derailing the investigation into what went wrong, or it only serves to demonstrate how wrong I was :) AFAICT there are very few situations, if any, in which anyone would look back at this commit and find a comment about .PHONY targets to be beneficial instead of just added noise. It doesn't meet my criteria for being added to the commit comment. May I have your Acked-By: without the addition, please? > If you were feeling dynamic, getting the gcc does (and maybe the make > docs) improved would be nice.

Indeed, but as you suggest I don't think this is a case that depends on parallelism. Make tends to be fairly deterministic about what rules *mean*, even when race conditions exist in parallel execution of those rules. > Sorry that this was frustrating in this case, but I think that some of > the lossage from our (sometimes appalling) makefiles has arisen due to > patches being committed that appeared to work at the time. So I don't > think your research was wasted effort. Well, I refuted^Wrebutted *one* theory, which turns out to be incorrect, about *one* way in which it might fail. This is far from being a formal proof of correctness of my patch. I suppose 'wasted' is a very subjective term and let's not argue over whether it was wasted or not. But equally, we are no further forward than we were before I had an erroneous theory to dispute. Really no further forward in any way, because I didn't get to spend that time doing anything more useful either. --=-uRhOXIyydiujpRksvBt+ Content-Type: application/x-pkcs7-signature; name="smime.p7s"

Most of them where triggering with core-scheduling enabled, and I don't recall any of them which looked similar or related to this. Still, it's possible that the same issue causes different symptoms, and hence that maybe one of the patches would fix this too. But if it's difficult for you to try upstream, let's maybe wait and see if he has an opinion about this bug. I have just one question: > (XEN) Assertion 'c2rqd(ops, sched_unit_master(unit)) =3D=3D svc->rqd' > failed at sched_credit2.c:2137 > (XEN) ----[ Xen-4.13.0 x86_64 debug=3Dy Not tainted ]---- > [...] > (XEN) Xen call trace: > (XEN) [] R > sched_credit2.c#csched2_unit_wake+0x174/0x176 > (XEN) [] F vcpu_wake+0xdd/0x3ff > (XEN) [] F domain_unpause+0x2f/0x3b > (XEN) [] F > domain_unpause_by_systemcontroller+0x40/0x60 > (XEN) [] F do_domctl+0x9e4/0x1952 > (XEN) [] F pv_hypercall+0x548/0x560 > (XEN) [] F lstar_enter+0x112/0x120 > (XEN)=20 > (XEN)=20 > (XEN) **************************************** > (XEN) Panic on CPU 0: > (XEN) Assertion 'c2rqd(ops, sched_unit_master(unit)) =3D=3D svc->rqd' > failed at sched_credit2.c:2137 > (XEN) **************************************** > (XEN)=20 > Do you remember (or can easily test) whether this was also occurring on Xen 4.12, i.e., without core-scheduling code even being there, when this ASSERT was: ASSERT(c2rqd(ops, vc->processor) =3D=3D svc->rqd ); If no, that might mean we have some scheduling resource and/or master CPU issue on the S3 resume path.

This is PV dom0, running on Xen nested inside KVM. I don't really know when it started happening, I've got it on at least those versions: - Xen 4.8.5 + Linux dom0 4.19.94 - Xen 4.13.0 + Linux dom0 5.4.25 - at least once also on physical hardware (Xen 4.13.0 + Linux dom0 5.4.x) Contrary to the other issue, here suspend is not involved, it is just intensive system usage - multiple VM startups, involving some I/O, network traffic etc. This happens rather rarely (I'd say about 1-3% of tests). To be honest, I'm not really sure if the bug is in Xen-related code at all, or if Xen functions are in the call trace only because it is PV dom0.

Yes, 100% agreed. And I'll even concede that for the cases of moving code around that happens to not conform to the current style, and asking contributors to fix it up as they go. I was agreeing with you on that point, while simultaneously telling Julien "nah, I'll fix it while I'm here" when he suggested that I *not* realign the PGC_state bit definitions. > The mentioned Linux origin of some of the particularly bad > examples in our tree is why I view your "they cope with the Linux > community just fine" as not really applicable.

Jan, I would respectfully request that you take another look at your initial response, but put yourself in the shoes of a patch submitter: https://lists.xenproject.org/archives/html/xen-devel/2020-03/msg01171.html You mention a "simple" workaround... but the workaround I've been using is to manually remove the offending .o.d files, one at a time (or at least one directory at a time), until the broken build starts working again. Is that what you meant? And you really didn't ever consider that it should be fixed? And the substance of the response is basically saying "this is voodoo and we can't touch it or unspecified things might break, but I have no idea where to tell you to look." Looking back I realise that the concern about phony rules overriding pattern rules didn't even come from you; your concern was more nebulous and unaddressable. It looks like I came up with a straw man and shot *that* down in my later analysis (although that wasn't my intent; I think the concern about pattern rules really did come from somewhere). You asked a question about "why isn't this default behaviour", which is kind of a silly question when asking about an option (-MP) that was added to GCC almost a decade after the initial -MD behaviour was established. Of *course* they didn't retroactively change the default. Read that message again from the point of view of a contributor. Pretend it isn't even me; pretend it's someone attempting to make their first, trivial, improvement to the Xen ecosystem.

But subsuming the PGC_broken but into a 3-bit PGC_state makes sense, and we can't abandon that idea purely because we can't come up with a *name* that fills us with joy. There wasn't a *good* answer. I vacillated for a while, and picked the one that offended me least.

And I've learned over the years *not* to second-guess the optimisations that today's compiler might make, with the wind blowing in this particular direction. FWIW 'return (x =3D=3D 6 || x =3D=3D 7)' ends up being emitted by GCC on x8= 6 as subl $6, %edi xorl %eax, %eax cmpl $1, %edi setbe %al ret And 'return (x =3D=3D 5 || x =3D=3D 7)' gives: andl $-3, %edi xorl %eax, %eax cmpl $5, %edi sete %al ret So it does look like GCC is actually doing its job, on this occasion. But that's entirely beside the point, which is that I'm having some pointless discussion about compiler optimisation minuti=C3=A6 when fixing PGC_broken was *already* deep into yak-shaving for the improvement I was *actually* trying to make.

Perspective again. That distinction really doesn't matter. Perhaps you underestimate the weight your words carry, as a well-respected maintainer. You can't negate that effect purely by word tricks like saying 'I wonder'.=20 Because understatement is a very common tool in the English language, especially in British English =E2=80=94 and we've all seen people write "I wonder if you should..." when what was really meant was "I will set fire to you if you don't...".=20 Understatement like that doesn't work. It still derails the patch review. It just didn't need to be said, in that context. Let me repeat =E2=80=94 because I've only said it once today, I think, that your reviews are incredibly useful. I'm only asking that you recognise the weight that your 'wondering' can have, and recognise when something you are asking for is *subjective*. A review is not about "is this code precisely how it would look if I had written it myself", but it is about "is this code correct and maintainable". Sometimes, as in the example with the PGC_state_ naming above, there isn't a "nice" answer. We pick the solution that offends us least. And I completely understand as a maintainer, what it's like to be on the receiving end of such a choice. You think "that could be nicer"... and have to work through the alternatives yourself before you realise that actually, it was the best of the choices available. Each of the responses I've identified from you as 'excessive' has some merit, we can focus on each of them and you can justify them, to a certain extent. But as a whole, the effect is of a barrage of nitpicks of questionable utility which really does hinder forward progress. Let's try to focus on comments which will genuinely make the code better. It's not that we should deliberately stop paying attention to detail, or deliberately allow buggy and broken code into the tree. It's that we should be aware that "perfect is the enemy of good". For my part, I'll stop whining at you now. If I end up giving responses to parts of your code review which seem to be along the lines of "that's nice, dear, but I didn't think so and I did the typing", please hark back to this conversation. I'll try to phrase them more appropriately than that, but no promises :) Thanks. --=-WaBZV/SE9z6wr3O7AoSA Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment;

I didn't say "no way". Then you have completely missed my point about how subtly understating your 'objections' makes no difference at all to the outcome. But OK, I'll come back to that at the end. You have made your intent clear, more than once now, and we should take it on board. > Instead I asked back to see whether there's more background to this. > It is a useful piece of information to know that -MP post-dates -MD > by 10 or more years.

If you were to direct it towards someone who's even remotely inclined to feeling patronised, that is. :) > Yes, in the typical case, when there's a recognizable bug, the > reviewer would point this out.

I find this response to be purely obstructive and unhelpful. Your response to my patch was basically asking me to prove a negative, and I find myself surprised and disappointed that you cannot acknowledge that. I didn't think our viewpoints were really that far apart; perhaps I was wrong. If there was an actual bug =E2=80=94 or even the suspicion of a bug =E2=80= =94 I could understand it. But this is just voodoo "we're too scared to change things because we don't understand". We are better than that. You can be better than that. But I will take on board your comments about understatement and the fact that you hadn't actually said "no". In future I shall consider merely ignoring such interjections unless you explicitly state that you are blocking the acceptance of a patch. Or, I suppose, resorting to the style of monosyllabic answer that I had originally given in this case. I trust that maintainers will take that on board too, and that open "questions" from you in a thread will not be considered sufficient reason not to merge a patch. That seems to be what you're saying is your intent, yes?=20 --=-ynJz0RtDUKtRtXaZ0f9E Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"

Resolve this by introducing a new page state, PGC_state_uninitialised, expanding the PGC_state to 3 bits (8 possible values) by subsuming the PGC_broken bit into it and eliminating the redundant possible combinations of PGC_broken and various states. Pages which find their way into free_heap_pages() while still in PGC_state_uninitialised can thus be detected and properly rehabilitated, basically by passing them through init_heap_pages().

You can't just *declare* that the page was properly initialised, because it isn't true. There's a pathological case where the zone hasn't been initialised at all, because *all* the pages in that zone got handed out by the boot allocator or used for initrd etc.=20 The first pages 'freed' in that zone end up being used (in init_heap_pages) to create the zone structures. Likewise, it could include a page which init_heap_pages() doesn't actually *put* into the buddy allocator, to work around the cross-zone merge problem. It's fine to use that page and share it with a guest, but it can't ever be freed into the buddy allocator. > > @@ -1828,7 +1840,8 @@ static void init_heap_pages( > > nr_pages -=3D n; > > } > >=20 > > - free_heap_pages(pg + i, 0, scrub_debug || idle_scrub); >=20 > Would it be worth an ASSERT(!pg[i].count_info) here in case something > is added which erroneously modifies the page count info before this > is done?

It's intended to be safe in all cases, including pages which are allocated from the boot allocator to be used as page tables (cf. the early-vmap patches), etc. We kind of have to assume that it's safe to use the page for whatever purpose it was allocated for, for the lifetime of that usage. If *that* isn't true, we have bigger problems. The PGC_state_uninitialised thing is only about recycling it into the heap *later*, once the lifetime of that initial usage has ended. --=-AfL9J+gBkeJaQnwFZ4Kt Content-Type:

I am unconvinced of the veracity of this claim. We don't want to turn specific details of the current Xen buddy allocator part into of the implicit ABI of live update. That goes for the power-of-two zone boundaries, amongst other things. What if Xen receives LU state in which *all* pages in a given zone are marked as already in use? That's one of the cases in which we *really* want to pass through init_heap_pages() instead of just free_heap_pages(), in order to allocate the zone data structures for the first pages that get freed into that zone. What if Xen starts to exclude more pages, like the exclusion at zero? What if new Xen wants to exclude an additional page due to a hardware erratum? It can't take it away from existing domains (especially if there are assigned PCI devices) but it could be part of the vetting in init_heap_pages(), for example. My intent for PGC_state_uninitialised was to mark pages that haven't been through init_heap_pages(), whatever init_heap_pages() does in the current version of Xen. The pages which are "already in use" because they're inherited through LU state should be in PGC_state_uninitialised, shouldn't they? Perhaps if there's a need for a helper, it could be a companion function to init_heap_pages() which would return a boolean saying, "nah, I didn't want to do anything to this page anyway", which could short-circuit it into the PGC_state_inuse state. But I'm not sure I see the need for such an optimisation.=20 --=-qg8mIyGqetCZIhlMTeNL Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment;

It's my understanding (from reading the manual) that whatever gets appended to -Wa, is just passed to the assembler, in which case the compiler has no idea whether it's used by it or not. Which version of clang did you use to test it? Isn't it fine to just attempt to test if it works, and if the compiler complains just don't append it?

Removing the whole directory without giving time to the driver domain to execute it's hotplug scripts can indeed lead to issues, as there's no guarantee that the hotplug script won't use data in xenstore in order to perform the cleanup IIRC. My preferred option would be to wait for the backend directory to be removed by the driver domain, as I think it's the cleanest and likely safest approach. Thanks, Roger.

I think something else in the middle needs teaching about hard errors, and not to pull more data out of the ring. ~Andrew From xen-devel-bounces@lists.xenproject.org Mon Mar 23 16:15:33 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Mon, 23 Mar 2020 16:15:33 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jGPjc-0007S4-0x; Mon, 23 Mar 2020 16:15:28 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jGPja-0007Rz-6b for xen-devel@lists.xenproject.org; Mon, 23 Mar 2020 16:15:26 +0000 X-Inumbo-ID: 7fcbff8a-6d21-11ea-b34e-bc764e2007e4 Received: from mail-wm1-x343.google.com (unknown [2a00:1450:4864:20::343]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 7fcbff8a-6d21-11ea-b34e-bc764e2007e4; Mon, 23 Mar 2020 16:15:23 +0000 (UTC) Received: by mail-wm1-x343.google.com with SMTP id z18so15392wmk.2 for ; Mon, 23 Mar 2020 09:15:23 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=date:from:to:cc:subject:message-id:mime-version:content-disposition :user-agent; bh=dK9q3Q94O2osyjPbhuyCuLPxDZe5LnX41Erpc+KPsFs=; b=c2eJHVNLiIROpnr43VSYxVLjcsa8KrMBCAc8xM6ZL9fK4jaV7Yh+6NzOxC8DsGnABh lFEsOdvDur+yIN8mEkof7QL+O1FjwJhSiqkuVhnTPsUiswxMGCuBCzGI2PA6qMLezlLC T7Ye2RXuxoSlFVz9ra6XytD5KL9/14Jh3b108Qxy4xTVAnjMKJJ9DsMn8r3YhUZhKRvv iYdstxT9PAFI+l4/p+TzkuYo1LRIx0LUNU8a9ewfJJD1uI+AS0u79dhRTiRzhf73REVh GCIrTOIMOCyzCVkIRDuxuQ81tKrxhFwrqfZ5FG9l5UmlIiQgBE8SfS9+kA0jP7AEmJIA BwvQ== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:date:from:to:cc:subject:message-id:mime-version :content-disposition:user-agent; bh=dK9q3Q94O2osyjPbhuyCuLPxDZe5LnX41Erpc+KPsFs=; b=tmjhvdyPRGlmKH4/LK2LbMsehMDOF215P+clEkDsqFQaDrlGRWoKA1QtOX3AVkapGe 0X84RRFX1TiKiDxHtW2vGGWwo4wqmNIOPxJ8re8XZKMpMMmf7kgf8ZuC1ihYcscZItgl /dOc3672bw3ptVnk0G3Bf97MeUAXC6XxdrAF5H8NDLHQ7MI1wwvVdQPhhWNvqRtb+PeZ AcURkpTIkEy7FWtxQ5zL4vDZwkjMFaREtpc00xFr2e3peeQ5UQjRuLaFGgU058V4LDqj jApSe8beUehZ2lUvWcf0T5OgKDT79lruDpABp82Ab1Fddv4NHjUmeRofm1kAqLcgMmlG 8Ykg== X-Gm-Message-State: ANhLgQ2T4KgR2Rdc3ENJKtqAgAVFvD25cXvlCrjyXDHbJvNqVzs5PsDr MDpuvDTkZoChIlYzOzQjS0k= X-Google-Smtp-Source: ADFU+vunIFrJ+C9vxFIfCAsVjzj4m2fUsGTSU4P7MY6r49roIZecuFuuKMQVyQiyxRgmJJpGUSnvkw== X-Received: by 2002:a1c:2404:: with SMTP id k4mr27210339wmk.87.1584980120753; Mon, 23 Mar 2020 09:15:20 -0700 (PDT) Received: from kbp1-lhp-F74019 (ip-109-41-67-112.web.vodafone.de.

I'm afraid this is predictable. For most of these errors there is nothing else sensible that the client library could do. The connection has been rendered unuseable. In principle I guess it could reconnect to the socket, but this is a "should never happend" event. EBADF is a worrying error because in many cases it means something has messed up the process's fd space, which can easily lead to really bad behaviours. But having read the code in xenstore-ls, I see that as well as closing the fd it sets the variable containing the fd number to -1. So all future calls return EBADF. I think this is correct. Ian.

This is unnecessarily confusing (and in particular it confuses the Coverity Scan analysis, resulting in the false positive CID 1421919 where it thinks that we write off the end of the structure).

JIRA issue: https://xenproject.atlassian.net/browse/XEN-89 The fork operation is implemented as part of the "xl fork-vm" command: xl fork-vm -C -Q -m By default a fully functional fork is created. The user is in charge however to create the appropriate config file for the fork and to generate the QEMU save file before the fork-vm call is made. The config file needs to give the fork a new name at minimum but other settings may also require changes. Certain settings in the config file of both the parent and the fork have to be set to default. Details are documented. The interface also allows to split the forking into two steps: xl fork-vm --launch-dm no \ -m \ -p xl fork-vm --launch-dm late \ -C \ -Q \ The split creation model is useful when the VM needs to be created as fast as possible. The forked VM can be unpaused without the device model being launched to be monitored and accessed via VMI. Note however that without its device model running (depending on what is executing in the VM) it is bound to misbehave or even crash when its trying to access devices that would be emulated by QEMU. We anticipate that for certain use-cases this would be an acceptable situation, in case for example when fuzzing is performed of code segments that don't access such devices. Launching the device model requires the QEMU Xen savefile to be generated manually from the parent VM. This can be accomplished simply by connecting to its QMP socket and issuing the "xen-save-devices-state" command. For example using the standard tool socat these commands can be used to generate the file: socat - UNIX-CONNECT:/var/run/xen/qmp-libxl- { "execute": "qmp_capabilities" } { "execute": "xen-save-devices-state", \ "arguments": { "filename": "/path/to/save/qemu_state", \ "live": false} } At runtime the forked VM starts running with an empty p2m which gets lazily populated when the VM generates EPT faults, similar to how altp2m views are populated. If the memory access is a read-only access, the p2m entry is populated with a memory shared entry with its parent. For write memory accesses or in case memory sharing wasn't possible (for example in case a reference is held by a third party), a new page is allocated and the page contents are copied over from the parent VM. Forks can be further forked if needed, thus allowing for further memory savings. A VM fork reset hypercall is also added that allows the fork to be reset to the state it was just after a fork, also accessible via xl: xl fork-vm --fork-reset -p This is an optimization for cases where the forks are very short-lived and run without a device model, so resetting saves some time compared to creating a brand new fork provided the fork has not aquired a lot of memory. If the fork has a lot of memory deduplicated it is likely going to be faster to create a new fork from scratch and asynchronously destroying the old one. The series has been tested with Windows VMs and functions as expected. Linux VMs when forked from a running VM will have a frozen VNC screen. Linux VMs at this time can only be forked with a working device model when the parent VM was restored from a snapshot using "xl restore -p". This is a known limitation. Also note that PVHVM/PVH Linux guests have not been tested. Forking most likely works but PV devices and drivers would require additional wiring to set things up properly since the guests are unaware of the forking taking place, unlike the save/restore routine where the guest is made aware of the procedure. Forking time has been measured to be 0.0007s, device model launch to be around 1s depending largely on the number of devices being emulated. Fork resets have been measured to be 0.0001s under the optimal circumstances.

This allows the forked VM to reset into the same state the parent VM is in a faster way then creating a new fork would be. Measurements show about a 2x speedup during normal fuzzing operations. Performance may vary depending how much memory got allocated for the forked VM. If it has been completely deduplicated from the parent VM then creating a new fork would likely be more performant.

currently working on a Qubes OS server version (example architecture = can been seen at https://raw.githubusercontent.com/fepitre/qubes-mgmt-sal= t-qubes-server/devel-140320-extra/qubes-server.png). I'm using this confi= guration since several months on Qubes R4.0 (xen-4.8) and recently on Qub= es R4.1 (xen-4.13). I'm writing to you because since the beginning I'm ha= ving network performance issues that I never succeeded to solve. This setup is done on a HP Gen8 DL360p with 2*CPUs, 160GB memory, 1TB RAI= D6 SAS. On the picture I linked you, all the colored rectangles {zone}-* for zone= in (wan, dmz, lan, admin) are PVH VMs (Debian 10). There exist a VM not = drawn in the picture, called 'sys-net-interfaces' which holds four 1Gbits= Ethernet controllers of the server using PCI passthrough. It is a HVM wi= th Linux-based stubdomain. All the inner links between VMs are NAT interfaces. All the outer links o= n *-sys-net VMs are BRIDGE interfaces with backend 'sys-net-interfaces'. = In VM 'sys-net-interfaces' a LACP bond0 is done with two Ethernet control= lers, which is a trunk, then several vlan interfaces are generated with p= arent device this bond, and finally, bridges are created and associated t= o those vlans. Here are my issues. Consider one computer named 'PC-LAN' in LAN network a= nd another 'PC-DMZ' in DMZ network. The considered network path is the fo= llowing: PC-LAN (1) <-- B --> lan-sys-net (2) <-- N --> lan-sys-firewall (3) <-- = N --> dmz-sys-firewall (4) <-- N --> dmz-sys-net (5) <-- B --> PC-DMZ (6)= where B denotes bridge interface, N denotes NAT interface and numbers for= numbering machines. Up to 'wget', 'scp' (limited normally by ciphers), e= tc., I ran multiple iperf3 tests over 20 seconds for having a clearer vie= w of network issues. Example 1: Full path From (1) to (6): 165 Mbits/s From (2) to (6): 196 Mbits/s From (3) to (6): 205 Mbits/s From (4) to (6): 203 Mbits/s From (5) to (6): 714 Mbits/s Example 2: 'dmz-sys-net' as end node From (1) to (5): 194 Mbits/s From (2) to (5): 189 Mbits/s From (3) to (5): 258 Mbits/s From (4) to (5): 500 Mbits/s Example 3: 'lan-sys-net' as end node From (1) to (2): 830 Mbits/s I've another HP Gen8 with almost the same physical configuration and netw= ork configuration (LACP+vlan+bridges) running under Debian 10 as bare met= al KVM, and I obtain 1Gbits/s network workflows over bridges. The almost = physical configuration is due to the related mail I sent you in july 2019= '[Xen-devel] Ethernet PCI passthrough problem'. The provided Ethernet ca= rd with 4 ports (HP Ethernet 1Gb 4-port 331FLR Adapter) makes the driver = tg3 crashing when attaching those into a VM. So the Debian KVM has those = HP Ethernet controllers whereas on the Qubes server, it has a cheap PCI e= xpress 4 Ethernet Realtek 8169 card. Of course physical connections on the switches have been changed, 'switch= ed' between the two servers for eliminating any hardware problem. I had a look to https://wiki.xen.org/wiki/Network_Throughput_and_Performa= nce_Guide. Unfortunately, trying some change of options with 'ethtool' in= 'sys-net-interfaces', changing amount of RAM/VCPUs of it and other *-sys= -net, does not do that much. I'm writing to you for having some clues into where I can dig and what I = can look in order to put in evidence the bottleneck. If it's purely dom0 = side or backend network VM side (sys-net-interfaces) or elsewhere. I would like to thank you a lot in advance for any help on this problem.

HVM guest kernels can trigger this to DoS the host. To mitigate, in affected hardware, all EPT superpages are marked NX. When an instruction fetch violation is observed against the superpage, the superpage is shattered to 4k and has execute permissions restored. This prevents the guest kernel from being able to create the necessary preconditions in the iTLB to exploit the vulnerability. This does come with a workload-dependent performance overhead, caused by increased TLB pressure. Performance can be restored, if guest kernels are trusted not to mount an attack, by specifying ept=exec-sp on the command line.

HVM guest kernels can trigger this to DoS the host. To mitigate, in affected hardware, all EPT superpages are marked NX. When an instruction fetch violation is observed against the superpage, the superpage is shattered to 4k and has execute permissions restored. This prevents the guest kernel from being able to create the necessary preconditions in the iTLB to exploit the vulnerability. This does come with a workload-dependent performance overhead, caused by increased TLB pressure. Performance can be restored, if guest kernels are trusted not to mount an attack, by specifying ept=exec-sp on the command line.

I was going through how Xen support PCIe IOMMU ACS and all I could find is this: https://github.com/xen-project/xen/blob/master/xen/drivers/passthrough/pci.c#L608 which looks to me as an attempt of enabling ACS opportunistically, but still proceeding forward even if it fails. Am I missing something here? IOW, does Xen try to do any kind of fine grained ACS differentiation along the lines of what linux kernel is doing: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/quirks.c#n4299 Thanks, Roman.

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

In current xen codes, it use whole u64 interrupt_shadow to setup interrupt shadow, which will misuse other bit in VMCB offset 68h as part of interrupt_shadow. Add union intstat_t for VMCB offset 68h and fix codes to only use bit 0 as intr_shadow according to the new APM description.

So I'm confused - I had just replied twice to v6 patch 5/5. This series calls itself v4 and consists of the middle three patches of what v6 was. What's the deal? Is this really v7, and the two patches have been dropped / postponed?

Well, patch 1/3 is a revert of f96e1469, so just reverting f96e1469 gets us to that state. This patch is an attempt to clarify that nvmx_update_apicv is closely related to the Ack on exit feature, as it modifies SVI in order to signal the vector currently being serviced by the EXIT_INTR_INFO vmcs field. This was not obvious to me, as at first sight I assumed nvmx_update_apicv was actually injecting that vector into the guest. > iirc, that commit was introduced to enable > nested x2apic with apicv, and your very first version even just removed > the whole nvmx_update_apicv.

Yes, patch 3/3 is the one that fixed the issue. Note however that strangely enough removing the call to nvmx_update_apicv (as my first attempt to solve the issue) did fix it on one of my boxes. It depends a lot on the available vmx features AFAICT. > > > > if ( reason == EXIT_REASON_EXTERNAL_INTERRUPT && > > nvmx->intr.source == hvm_intsrc_lapic && > > @@ -1399,6 +1399,15 @@ static void nvmx_update_apicv(struct vcpu *v) > > ppr = vlapic_set_ppr(vlapic); > > WARN_ON((ppr & 0xf0) != (vector & 0xf0)); > > > > + /* > > + * SVI must be updated when the interrupt has been signaled using the > > + * Ack on exit feature, or else the currently in-service interrupt > > + * won't be respected. > > + * > > + * Note that this is specific to the fact that when doing a VMEXIT an > > + * interrupt might get delivered using the interrupt info vmcs field > > + * instead of being injected normally. > > + */ > > I'm not sure mentioning SVI specifically here is necessary, since all steps > here are required - updating iir, isr, rvi, svi, ppr, etc. It is just an emulation > of updating virtual APIC state as if a virtual interrupt delivery happens. Hm, it was hard for me to figure out that SVI is modified here in order to signal that the Ack on exit vector is currently in service, as opposed to being injected using the virtual interrupt delivery mechanism. I just wanted to clarify that the purpose of this function is not to inject the vector in intr_info, but rather to signal that such vector has already been injected using a different mechanism. I'm happy to reword this, but IMO it should be clear that the purpose of the function is not so much to inject an interrupt, but to update the virtual interrupt delivery field in order to signal that an interrupt has been injected using a different mechanism. Thanks, Roger.

But if Ack on exit is not set the GUEST_INTR_STATUS won't be changed by nvmx_intr_intercept, and hence there's no need to update the EOI exit map? If OTOH the GUEST_INTR_STATUS field is changed by vmx_intr_assist the bitmap will already be updated there. Thanks, Roger.

Marking the page as already used is no different to "PGC_state_unitialized" except the "struct page_info" and the internal of the buddy allocator would be properly setup for start rather than at free. > > What if Xen receives LU state in which *all* pages in a given zone are > marked as already in use?

I don't think it would be safe to continue to run a guest using pages that were excluded for an HW erratum. It would be safer to not restart the domain (or replace the page) in the target Xen if that's hapenning. > > My intent for PGC_state_uninitialised was to mark pages that haven't > been through init_heap_pages(), whatever init_heap_pages() does in the > current version of Xen. > > The pages which are "already in use" because they're inherited through > LU state should be in PGC_state_uninitialised, shouldn't they? I think using "PGC_state_unitialised" for preserved page is an abuse. I understand this is existing in other part of Xen (particularly on x86), but I would rather not try to add more. The PGC_state_unitialised may work for the current allocator because most of the fields are not going to be used after allocation. But it may not hold for any new allocator (I know the embedded folks are working on a new one). > > Perhaps if there's a need for a helper, it could be a companion > function to init_heap_pages() which would return a boolean saying, > "nah, I didn't want to do anything to this page anyway", which could > short-circuit it into the PGC_state_inuse state. But I'm not sure I see > the need for such an optimisation. I don't view it as an optimisation but as a way to avoid spreading the current misbehavior.

Subject: [Xen-devel] [PATCH] tools/xenstore: fix a use after free problem in xenstored X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Juergen Gross , Ian Jackson , Wei Liu Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Commit 562a1c0f7ef3fb ("tools/xenstore: dont unlink connection object twice") introduced a potential use after free problem in domain_cleanup(): after calling talloc_unlink() for domain->conn domain->conn is set to NULL. The problem is that domain is registered as talloc child of domain->conn, so it might be freed by the talloc_unlink() call.

In current xen codes, it use whole u64 interrupt_shadow to setup interrupt shadow, which will misuse other bit in VMCB offset 68h as part of interrupt_shadow. Add union intstat_t for VMCB offset 68h and fix codes to only use bit 0 as intr_shadow according to the new APM description.

This restriction is clearly used for coordinated mode but it also restricts view switching in the external mode as well. I had a good example to start with, let's say we have one external agent in dom0 that uses view1 and view2 and the logic requires the switch between the views. At this point VMFUNC is available to the guest so with a simple asm code it can witch to view 0. At this time the external agent is not aware that the view has switched and further more view0 was not supposed to be in the main logic so it crashes. This example can be extended to any number of views. I hope it can paint a more clear picture of what this patch is trying to achive. > btw I'm not sure why altp2m invents two names per mode, and their > mapping looks a bit weird. e.g. isn't 'coordinated' mode sound more > like 'mixed' mode?

Are you aiming for a > scenario that dom0 may register 10 views, with 5 views visible to > vmfunc with the other 5 views switched by dom0 itself? That is one scenario, another can be that dom0 has a number of views created and in some time it wants to be sure that only some of the views can be switched, saving the rest and making them visible when the time is right. Sure the example given up is another example.

AFAICT those problems affect different kind of hardware, so it doesn't make much difference. IMO f96e1469ad06b6 should be reverted because it's plain wrong, and albeit it seemed to fix the issue in one of my boxes it was just luck. I don't thinks it's going to make matters worse, as osstest is already blocked, but reverting it alone without the rest of the series is not going to unblock osstest either. If you agree it's wrong I think it could go in now, even if it's just to avoid having to repost it with newer versions of the series. Thanks, Roger.

That only happens when the vcpu is in nested mode (nestedhvm_vcpu_in_guestmode == true). That would be the case before a vmexit, at least for the first call to vmx_intr_assist if there are pending softirqs.

Yes, the patch that actually fixes the issue in the box I've been testing with is 3/3.

Both RVI and SVI are additional requirements > when virtual APIC page is in-use while virtual interrupt delivery is not > used, i.e. when ack-on-exit is set. Right, so if I understand this correctly: - SVI: must be updated when Ack on exit is used, to signal the current in service interrupt which has been injected using a mechanism different than virtual interrupts. - RVI: should always be updated if there are pending interrupts to be delivered. Note that the interrupt signaled in the INTR_INFO field if Ack on exit is enabled is not considered pending anymore. So I think RVI should always be updated, regardless of whether Ack on exit is used or not. Do you agree? Thanks, Roger.

I'd appreciate though if at least some of the earlier ones could go in rather sooner than later. Patch 1 functionally (for the test harness) depends on "libx86/CPUID: fix (not just) leaf 7 processing", while at least patch 2 contextually depends on "x86emul: disable FPU/MMX/SIMD insn emulation when !HVM". 1: x86emul: support AVX512_BF16 insns 2: x86emul: support MOVDIRI insn 3: x86: determine HAVE_AS_* just once 4: x86: move back clang no integrated assembler tests 5: x86emul: support MOVDIR64B insn 6: x86emul: support ENQCMD insn 7: x86/HVM: scale MPERF values reported to guests (on AMD) 8: x86emul: support RDPRU 9: x86/HVM: don't needlessly intercept APERF/MPERF/TSC MSR reads 10: x86emul: support MCOMMIT See individual patches for changes from v4 (which was mistakenly sent out with a v3 tag).

It appears to be a shadow copy of EFLAGS.IF which is only written on vmexit, and never consumed, but this is based on Appendix B which is the only reference I can find to the field at all.  Neither the VMRUN/#VMEXIT descriptions discuss it at all. Given its position next to the (ambiguous) INTERRUPT_SHADOW, it just might actually distinguish the STI shadow from the MovSS shadow, but it could only do that by not behaving as described, and being asymmetric with EFLAGS.  I don't have time to investigate this right now. We need the field described in Xen to set it appropriately for virtual vmexit, but I think that is the extent of what we need to do. ~Andrew From xen-devel-bounces@lists.xenproject.org Tue Mar 24 12:29:13 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Tue, 24 Mar 2020 12:29:13 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jGigD-0005WF-4l;

This results in proper rebuilds (via make dependencies) in case the compiler used changes between builds. It additionally eases inspection of which assembler features were actually found usable. Some trickery is needed to avoid header generation itself to try to include the to-be/not-yet-generated header. Since the definitions in generated/config.h, previously having been command line options, might even affect xen/config.h or its descendants, move adding of the -include option for the latter after inclusion of the per-arch Rules.mk. Use the occasion to also move the most general -I option to the common Rules.mk. Signed-off-by: Jan Beulich --- v5: Re-base. v4: New. --- An alternative to the $(MAKECMDGOALS) trickery would be to make generation of generated/config.h part of the asm-offsets.s rule, instead of adding it as a dependency there.

Note that the ISA extensions document revision 037 doesn't specify exception behavior for ModRM.mod == 0b11; assuming #UD here. No tests are being added to the harness - this would be quite hard, we can't just issue the insns against RAM. Their similarity with MOVDIR64B should have the test case there be god enough to cover any fundamental flaws. Signed-off-by: Jan Beulich --- TBD: This doesn't (can't) consult PASID translation tables yet, as we have no VMX code for this so far.

Hence when processing such reads in software we too should scale the values. While we don't currently (yet) expose the underlying feature flags, besides us allowing the MSRs to be read nevertheless, RDPRU is going to expose the values even to user space.

For instance, on Arm32 this will be a call to vmap(). So you want to check the return.

I think all of the effects can be explained by the way how pinning with core scheduling is implemented. This does not mean that the information presented to the user shouldn't be adapted. Basically pinning of any vcpu will just affect the "master"-vcpu of a virtual core (sibling 0). It will happily accept any setting as long as any "master"-cpu of a core is in the resulting set of cpus. All vcpus of a virtual core share the same pinnings. I think this explains all of the above scenarios. IMO there are the following possibilities for reporting those pinnings to the user: 1. As today, documenting the output. Not very nice IMO, but the least effort. 2. Just print one line for each virtual cpu/core/socket, like: Windows 10 (64-bit) (1) 5 0-1 0-1 -b- 1646.7 0-1 / all This has the disadvantage of dropping the per-vcpu time in favor of per-vcore time, OTOH this is reflecting reality. 3. Print the effective pinnings: Windows 10 (64-bit) (1) 5 0 0 -b- 1646.7 0 / all Windows 10 (64-bit) (1) 5 1 1 -b- 1646.7 1 / all Should be rather easy to do. Thoughts?

If so, I am fine with it, and it seems like a > good idea. I don't have useful information on which Xen bitness each platform can boot or support, so I can't really add those "depends on". But that could be done in a follow-up. > The other new generic earlyprintk options, the ones that only depend on > the uart driver, from EARLY_UART_CHOICE_8250 to EARLY_UART_CHOICE_SCIF, > it feels more natural to leave them without a specific arch dependency. That would mean adding drivers for both arm32 and arm64. For example, debug-cadence.inc is only available in arm64/. So if someone selects arm32 and the cadence early uart driver, there's going to be a compile error. That's the only reason on why I've added "depends on" on all EARLY_UART_CHOICE_*.

It would mean that libxl must have a way to tell that pinning failed because pinning was not being done to a "master CPU". I guess it's doable, but perhaps it's not the top priority, assuming we have (and we put in place, if we still don't) good documentation on how pinning works in this operational mode. That would make a good article/blog post, I think. > > 3. xl vcpu-pin 5 0 1-2 > > Windows 10 (64-bit) (1) 5 0 2 =20 > > -b- 1646.7 1-2 / all > > Windows 10 (64-bit) (1) 5 1 3 =20 > > -b- 1651.6 1-2 / all > > ^ =20 > > ^^^ > > Here is a CPU / affinity mismatch again, but the more > > interesting fact > > is that setting 1-2 is allowed at all, I'd expect CPU would > > never be set > > to 1 with such settings. > >=20 This is the situation I'm most concerned of. Mostly, because I think a user might be surprised to see the command (1) not failing and (2) having the effect that it has. I think that, in this case, we should either fail, or adjust the affinity to 2-3. If we do the latter, we should inform the user about that. There's something similar in libxl already (related to soft and hard affinity, where we set a mask, then we check what's been actually setup by Xen and act accordingly). Thoughts? I'd go for a mix of 1 and 3, i.e., I'd do: > 1. As today, documenting the output. > Not very nice IMO, but the least effort. >=20 This, i.e., we definitely need more documentation and we need to make sure it's visible enough. > 2.

I actually would go as far as changing the mapping we've been given and store the effective one(s) in `cpu_hard_affinity`, etc, in Xen. Of course, as said above, we'd need to inform the user that this has happened.

Multiple domain destructions in parallel now spin for the global heap lock when freeing memory and could spend a long time before the next hypercall continuation. In contrast, after dropping that commit, parallel domain destructions will just fail to take the domctl lock, creating a hypercall continuation and backing off immediately, allowing the thread that holds the lock to destroy a domain much more quickly and allowing backed-off threads to process events and irqs. On a 144-core server with 4TiB of memory, destroying 32 guests (each with 4 vcpus and 122GiB memory) simultaneously takes: before the revert: 29 minutes after the revert: 6 minutes This is timed between the first page and the very last page of all 32 guests is released back to the heap. This reverts commit 228ab9992ffb1d8f9d2475f2581e68b2913acb88.

I'm not at all happy to see this reverted; instead I was hoping that we could drop the domctl lock in further cases. If a lack of continuations is the problem, did you try forcing them to occur more frequently? > In contrast, > after dropping that commit, parallel domain destructions will just fail > to take the domctl lock, creating a hypercall continuation and backing > off immediately, allowing the thread that holds the lock to destroy a > domain much more quickly and allowing backed-off threads to process > events and irqs. > > On a 144-core server with 4TiB of memory, destroying 32 guests (each > with 4 vcpus and 122GiB memory) simultaneously takes: > > before the revert: 29 minutes > after the revert: 6 minutes This wants comparing against numbers demonstrating the bad effects of the global domctl lock. Iirc they were quite a bit higher than 6 min, perhaps depending on guest properties.

The internals of the buddy allocator *cannot* be set up properly for a page which it would not actually give out =E2=80=94 like the zero page. We *could* do some tricks to allocate the zone structures for zones which *do* exist but contain only "pre-allocated" pages so the buddy allocator has never seen those zones... yet. > I think using "PGC_state_unitialised" for preserved page is an abuse.

I am perfectly happy to try avoiding PGC_state_uninitialised for pages which are "in use" at boot time due to live update. All I insist on is that you explicitly describe the ABI constraints that it imposes, if any. For example, that hack which stops the buddy allocator from giving out page zero: Could we have live updated from a Xen without that hack, to a Xen which has it? With page zero already given out to a domain? With PGC_state_initialised and passing the page through init_heap_pages() if/when it ever gets freed, my answer would be 'yes'. What's yours? How would we cope with a situation like that, over LU? --=-W2JqeeO3aZ0bZLdOj7yi Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s"

With page zero already given out to a domain? The buddy allocator could never have given out page 0 on x86 because it is part of the first MB of the RAM (see arch_init_memory() in arch/x86/mm.c). AFAIK, the first MB cannot be freed.. The change in the buddy allocator was to address the Arm side and also make clear this was a problem this is a weakness of the allocator. > What's yours? How would we cope with a situation like that, over LU? When do you expect the pages to be carved out from the buddy allocator? I can see only two situations: 1) Workaround a bug in the allocator. 2) A CPU errata requiring to not use memory. In the case of 1), it is still safe for a domain to run with that page. However, we don't want to give it back to the page allocator. A solution is to mark them as "offlining/broken". Alternatively, you could remove the swap the page (see more below). In the case of 2), it is not safe for a domain to run with that page. So it is probably best to swap the pages with a new one. For HVM domain (including the P2M), it should be easy. For PV domain, I am not entirely sure if that's feasible.

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

So please provide information > on the setups you think it will make it worse. I did never observe the issue myself - let's see whether one of the SUSE people possibly involved in this back then recall (or have further pointers; Jim, Charles?), or whether any of the (partly former) Citrix folks do. My vague recollection is that the issue was the tool stack as a whole stalling for far too long in particular when destroying very large guests. One important aspect not discussed in the commit message at all is that holding the domctl lock block basically _all_ tool stack operations (including e.g. creation of new guests), whereas the new issue attempted to be addressed is limited to just domain cleanup.

AMD CPUs |3 into %cs.sel, but don't make an equivalent adjustment for %ss.sel, and simply take MSR_START.SYSRET_CS + 8. If you aren't careful with MSR_STAR, SYSRET will return to userspace with mismatching RPL/DPL and userspace can really find itself with an %ss with an RPL of 0.  (Of course, when you take an interrupt and attempt to IRET back to this context, things fall apart). I discovered this entirely by accident in XTF, but it is confirmed by careful reading of the AMD SYSRET pseudocode. > + cs.sel = op_bytes == 8 ? sreg.sel + 8 : sreg.sel - 8; > + > + cs.base = sreg.base = 0; /* flat segment */ > + cs.limit = sreg.limit = ~0u; /* 4GB limit */ > + cs.attr = 0xcfb; /* G+DB+P+DPL3+S+Code */ > + sreg.attr = 0xcf3; /* G+DB+P+DPL3+S+Data */ Again, that would be the logical behaviour... AMD CPU's don't update anything but %ss.sel, and even comment the fact in pseudocode now. This was discovered by Andy Luto, where he found that taking an interrupt (unconditionally sets %ss to NUL), and opportunistic sysret back to 32bit userspace lets userspace see a sane %ss value, but with the attrs still empty, and the stack unusable. > + > +#ifdef __x86_64__ > + if ( mode_64bit() ) > + { > + if ( op_bytes == 8 ) > + { > + cs.attr = 0xafb; /* L+DB+P+DPL3+S+Code */ > + generate_exception_if(!is_canonical_address(_regs.rcx) && > + !amd_like(ctxt), EXC_GP, 0); Wherever this ends up living, I think it needs calling out with a comment /* CVE-xxx, Intel privilege escalation hole */, as it is a very subtle piece of vendor specific behaviour.

I had it here first, then moved it down to avoid yet another mode_64bit() instance.

I'd rather not - this exception behavior is spelled out by the SDM, and hence imo pretty likely to be followed by clones.

Please reply for items you would like to see in 4.14 so that people have an idea what is going on and prioritise accordingly. You're welcome to provide description and use cases of the feature you're working on. = Timeline = We now adopt a fixed cut-off date scheme. We will release about every 8 months. The critical dates for Xen 4.14 are as follows: ---> We are here * Last posting date: May 1st, 2020 * Hard code freeze: May 22nd, 2020 * Release: June 26th, 2020 Note that we don't have a freeze exception scheme anymore. All patches that wish to go into 4.14 must be posted initially no later than the last posting date and finally no later than the hard code freeze. All patches posted after that date will be automatically queued into next release. RCs will be arranged immediately after freeze. There is also a jira instance to track all the tasks (not only big) for the project. See: https://xenproject.atlassian.net/projects/XEN/issues. Some of the tasks tracked by this e-mail also have a corresponding jira task referred by XEN-N. There is a version number for patch series associated to each feature. Can each owner send an update giving the latest version number if the series has been re-posted? Also, can the owners of any completed items please respond so that the item can be moved into the 'Completed' section. = Projects = == Hypervisor == * Live-Updating Xen (RFC v2) - David Woodhouse - The latest code is available at https://xenbits.xen.org/gitweb/?p=people/dwmw2/xen.git;a=shortlog;h=refs/heads/lu-master - Project wiki page at https://wiki.xenproject.org/wiki/Live-Updating_Xen * Non-Cooperative Live Migration (v7 (design docs)) - Paul Durrant * Secret Hiding (v5) - Hongyan Xia * Hypervisor file system (v6) - Juergen Gross === x86 === * Linux stub domains (v4) - Marek Marczykowski-Górecki * Virtualise MSR_ARCH_CAPS for guests - Andrew Cooper * AMD hardware mitigations (Rome) - Andrew Cooper * Xen ioreq server (v3) - Roger Pau Monne * Memory read caching in emulation (v5) - Jan Beulich * Instruction emulator improvements - Jan Beulich * VM forking (v11) - Tamas K Lengyel === ARM === == Completed == Paul Durrant From xen-devel-bounces@lists.xenproject.org Wed Mar 25 10:19:33 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 10:19:33 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH38H-00017w-E4; Wed, 25 Mar 2020 10:19:33 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH38F-00017d-Pi for xen-devel@lists.xenproject.org; Wed, 25 Mar 2020 10:19:31 +0000 X-Inumbo-ID: 1cf42d9e-6e82-11ea-85c5-12813bfff9fa Received: from esa4.hc3370-68.iphmx.com (unknown [216.71.155.144]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id 1cf42d9e-6e82-11ea-85c5-12813bfff9fa; Wed, 25 Mar 2020 10:19:30 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=citrix.com; s=securemail; t=1585131570; h=from:to:cc:subject:date:message-id:mime-version: content-transfer-encoding; bh=XEgDZuOwwNyS0bjk2/uEkpNpG2eAcVVSjm/B+WEIYnY=; b=S+a4MqkGQif2DODTtC0mEpXMqvPr4hGkrtQfMFyRaTYoPkdanLCFI9ex J+Eb7thOHCDaIbTiugNgfqBZJqQL5jjIdOLvb833xihh4eu8tliA/pHIe 2fmGBkYAVj5CvL8kH177LkmVt/aLL6/1LLyOwGYJtHuw/+zoWn0BTl1NK 8=; Authentication-Results: esa4.hc3370-68.iphmx.com; dkim=none (message not signed) header.i=none; spf=None smtp.pra=roger.pau@citrix.com; spf=Pass smtp.mailfrom=roger.pau@citrix.com; spf=None smtp.helo=postmaster@mail.citrix.com Received-SPF: None (esa4.hc3370-68.iphmx.com: no sender authenticity information available from domain of roger.pau@citrix.com) identity=pra; client-ip=162.221.158.21; receiver=esa4.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="roger.pau@citrix.com"; x-conformance=sidf_compatible Received-SPF: Pass (esa4.hc3370-68.iphmx.com: domain of roger.pau@citrix.com designates 162.221.158.21 as permitted sender) identity=mailfrom; client-ip=162.221.158.21; receiver=esa4.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="roger.pau@citrix.com"; x-conformance=sidf_compatible; x-record-type="v=spf1"; x-record-text="v=spf1 ip4:209.167.231.154 ip4:178.63.86.133 ip4:195.66.111.40/30 ip4:85.115.9.32/28 ip4:199.102.83.4 ip4:192.28.146.160 ip4:192.28.146.107 ip4:216.52.6.88 ip4:216.52.6.188 ip4:162.221.158.21 ip4:162.221.156.83 ip4:168.245.78.127 ~all" Received-SPF: None (esa4.hc3370-68.iphmx.com: no sender authenticity information available from domain of postmaster@mail.citrix.com) identity=helo; client-ip=162.221.158.21; receiver=esa4.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="postmaster@mail.citrix.com"; x-conformance=sidf_compatible IronPort-SDR: 9JlBUHZpC4DsvhODgViMwrmkhlKfYpHlbJ5q++SWHbWHIvSjCp4Glru0Hwh3JSpIGxhC/p9tzM TGz6ZVCsaP2+/wcP0rfNIsiEo6Ua8yCIja2VMd1ENSWXfkNxzhsabq/UyVorOm28d4cGpWRLG5 lUVOCGlgKl9Assn4IBgIYI/FRYf+k3buhC6HeE9X/sdjVfN1iSugACs6hDTUEDJuo58J6GFM1w p/oEhp9ZFUaez7SO0fHU5Zx3oUIBsCahB0jkjJpDbhuy8bUJlgY5TSgmGCJwCJHyqAzXS1swWr b+E= X-SBRS: 2.7 X-MesageID: 15252273 X-Ironport-Server: esa4.hc3370-68.iphmx.com X-Remote-IP: 162.221.158.21 X-Policy: $RELAYED X-IronPort-AV: E=Sophos;i="5.72,304,1580792400"; d="scan'208";a="15252273" From: Roger Pau Monne To: Date: Wed, 25 Mar 2020 11:19:06 +0100 Message-ID: <20200325101910.29168-1-roger.pau@citrix.com> X-Mailer: git-send-email 2.26.0 MIME-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 8bit Subject: [Xen-devel] [PATCH v2 0/4] x86/nvmx: fixes for interrupt injection X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Kevin Tian , Jun Nakajima , Wei Liu , Andrew Cooper , Jan Beulich , Roger Pau Monne Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Hello, osstest identified a regression caused by my earlier attempt to fix interrupt injection when using nested VMX. This series aims to fix the regression, and should unblock several osstest branches. The following report is from osstest with this series applied: http://logs.test-lab.xenproject.org/osstest/logs/148979/ Note the last patch (4/4) is the one that actually fixes the issue. Xen will always use the Ack on exit feature so patches 2/4 and 3/4 don't change the functionality when running a nested Xen, as it always requires SVI to be updated. Thanks, Roger.

Updating RVI however is not tied to the Ack on exit feature, as it signals the next vector to be injected, and hence should always be updated to the next pending vector, regardless of whether Ack on exit is enabled.

It would be nice to have a more precise date that traces a vulnerability (XSA) to its discovery rather than the public release date. Currently, I'm parsing any references from NVD/CVE and analyzing the dates. For older XSA, this works better than from newer ones. Is there any other place that I could find this information?

I'm a Ph.D. candidate in UC (Portug= al) working with Xen's vulnerability discovery process, right now focus= ing on modeling, and I'd like to understand the process before the disc= losure (by XSA or CVE/NVD). =C2=A0

It would be nice to have a more p= recise date that traces a vulnerability (XSA) to its discovery rather than = the public release date.

Currently, =C2=A0I'm parsing any refer= ences from NVD/CVE and analyzing the dates. For older XSA, this works bette= r than from newer ones.

Is there any other place that I could find = this information?

Yes, the domain handling the backend needs to watch .../state, while the control domain (where the toolstack actually runs) would need to watch .../ AFAICT. As you say, I think you could maybe reuse some of the code and add a special case for the toolstack domain when the backend runs in a driver domain. Thanks, Roger.

Will change. The main reason why my 204 followon series is still pending is because I never got around to completing an XTF test for all of these corner cases. I'm happy to drop my series to Xen in light of this series of yours, but I'd still like to complete the XTF side of things at some point. >>> + >>> +#ifdef __x86_64__ >>> + if ( mode_64bit() ) >>> + { >>> + if ( op_bytes == 8 ) >>> + { >>> + cs.attr = 0xafb; /* L+DB+P+DPL3+S+Code */ >>> + generate_exception_if(!is_canonical_address(_regs.rcx) && >>> + !amd_like(ctxt), EXC_GP, 0); >> Wherever this ends up living, I think it needs calling out with a >> comment /* CVE-xxx, Intel privilege escalation hole */, as it is a very >> subtle piece of vendor specific behaviour. >> >> Do we have a Centaur/other CPU to try with?  I'd err on the side of >> going with == Intel rather than !AMD to avoid introducing known >> vulnerabilities into models which stand half a chance of not being affected. > I'd rather not - this exception behavior is spelled out by the > SDM, and hence imo pretty likely to be followed by clones. In pseudocode which certainly used to state somewhere "for reference only, and not to be taken as an precise specification of behaviour".  (And yes - that statement was still at the beginning of Vol2 when Intel also claimed that "SYSRET was working according to the spec" in the embargo period of XSA-7, because I called them out on it). And anyway - it is a part of the AMD64 spec, not the Intel32 spec.  A 3rd party implementing it for 64bit support is more likely to go with AMD's writings of how it behaves. > While I do have a VIA box somewhere, it's not stable enough to > run for more than a couple of minutes. Fundamentally, it boils down to this. Intel behaviour leaves a privilege escalation vulnerability available to userspace. Assuming AMD behaviour for unknown parts is the safer course of action, because we don't need to issue an XSA/CVE to fix the emulator when it turns out that we're wrong. ~Andrew From xen-devel-bounces@lists.xenproject.org Wed Mar 25 10:55:24 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 10:55:24 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH3gs-0005Ow-Bh; Wed, 25 Mar 2020 10:55:18 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH3gr-0005Ol-57 for xen-devel@lists.xenproject.org; Wed, 25 Mar 2020 10:55:17 +0000 X-Inumbo-ID: 1bca5d9f-6e87-11ea-85cc-12813bfff9fa Received: from mx2.suse.de (unknown [195.135.220.15]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id 1bca5d9f-6e87-11ea-85cc-12813bfff9fa; Wed, 25 Mar 2020 10:55:15 +0000 (UTC) X-Virus-Scanned: by amavisd-new at test-mx.suse.de Received: from relay2.suse.de (unknown [195.135.220.254]) by mx2.suse.de (Postfix) with ESMTP id 1188AACBD; Wed, 25 Mar 2020 10:55:15 +0000 (UTC) From: Juergen Gross To: xen-devel@lists.xenproject.org Date: Wed, 25 Mar 2020 11:55:09 +0100 Message-Id: <20200325105511.20882-4-jgross@suse.com> X-Mailer: git-send-email 2.16.4 In-Reply-To: <20200325105511.20882-1-jgross@suse.com> References: <20200325105511.20882-1-jgross@suse.com> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Subject: [Xen-devel] [PATCH v7 3/5] xen: don't process rcu callbacks when holding a rcu_read_lock() X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Juergen Gross , Stefano Stabellini , Julien Grall , Wei Liu , Andrew Cooper , Ian Jackson , George Dunlap , Jan Beulich Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Some keyhandlers are calling process_pending_softirqs() while holding a rcu_read_lock().

It is raising sched softirqs without any real need and it requires tasklets for rcu_barrier(), which interacts badly with core scheduling. This small series repairs those issues. Additionally some ASSERT()s are added for verification of sane rcu handling. In order to avoid those triggering right away the obvious violations are fixed. This includes making rcu locking functions type safe.

As stop_machine_run() is using tasklets this requires scheduling of idle vcpus on all cpus imposing the need to call rcu_barrier() on idle cpus only in case of core scheduling being active, as otherwise a scheduling deadlock would occur. There is no need at all to do the syncing of the cpus in tasklets, as rcu activity is started in __do_softirq() called whenever softirq activity is allowed. So rcu_barrier() can easily be modified to use softirq for synchronization of the cpus no longer requiring any scheduling activity. As there already is a rcu softirq reuse that for the synchronization. Remove the barrier element from struct rcu_data as it isn't used. Finally switch rcu_barrier() to return void as it now can never fail.

Add ASSERT()s in debug builds in order to catch any violations. For that purpose modify rcu_read_[un]lock() to use a dedicated percpu counter additional to preempt_[en|dis]able() as this enables to test that condition in __do_softirq() (ASSERT_NOT_IN_ATOMIC() is not usable there due to __cpu_up() calling process_pending_softirqs() while holding the cpu hotplug lock). While at it switch the rcu_read_[un]lock() implementation to static inline functions instead of macros.

Upon re-reading I'm now confused - are you suggesting to also drop the EFER.SCE check? That's not what you said in reply to 6/7. If so, what's your thinking behind saying so? If I'm to guess, this may go along the lines of you suggesting to drop the explicit CPUID checks from SYSENTER/SYSEXIT as well, but I'm not seeing there either why you would think this way (albeit there it's also a little vague what exact changes you're thinking of at the MSR handling side).

Since I think ... > + size < (blob_size = /* Insufficient space for patch? */ > + get_totalsize(&mc->hdr)) ) ... this wants to come after the two version checks, how about lifting the printk() here? The other user of microcode_sanity_check() is an ASSERT(), where it's rather less relevant to have such a printk().

Or else - why did you add them? This (to me at least) doesn't e.g. make any more clear that the fields may be zero on old hardware.

I've got some ideas for an AMD series given the replies I got, and will be able to do an equivalent microcode_amd => microcode_patch folding on that side.  There is also further work to do, including unbreaking the OSVW logic (which has been totally clobbered by the start/end_update debacle). However, given that it taken this whole series to make the transition look safe on the Intel side, I really don't see a way of doing this "earlier". In particular, no amount of ifdefary suggested below can AFAICT make it safe to do this transform without having microcode_patch opaque to being with. Yes - there is a bit of churn, but I can't see a safe alternative. ~Andrew > Possibly, to limit code churn there, ... > >> --- a/xen/arch/x86/cpu/microcode/intel.c >> +++ b/xen/arch/x86/cpu/microcode/intel.c >> @@ -32,17 +32,12 @@ >> >> #define pr_debug(x...)

From this perspective I also think that having MFN and GFN conversions next to each other may be more confusing than helpful, the more that there are no uses introduced here for the latter. When applied to HVM guests, xen_pfn_to_cr3() also shouldn't be used, as that's a PV construct in the public headers. Yet I thing conversions to/from GFNs should first and foremost be applicable to HVM guests. A possible route to go may be to e.g. accompany {xen,compat}_pfn_to_cr3() with {xen,compat}_mfn_to_cr3(), and leave the GFN aspect out until such patch that would actually use them (which may then make clear that these actually want to live in a header specifically applicable to translated guests).

We definitely need to do this, so thanks for investing the time. I think though that we want to settle up front (and perhaps record in a comment in the new header) what is or is not suitable to go into the new header.

We encountered problem while running xen with new firmware which implement the bit[1] of the VMCB offset 68h: the DomU stopped when running seabios. We debugged the seabios code and found that the seabios hung after call16_int10(). Then we debugged the xen code, and found the cause at this place in svm_get_interrupt_shadow(): if ( vmcb->interrupt_shadow ) intr_shadow |= HVM_INTR_SHADOW_MOV_SS | HVM_INTR_SHADOW_STI; the conditional is true if bit[1] is 1 even though bit[0] is zero. If just only use bit[0] in the conditional, the problem is solved, DomU will run successfully. -- Regards, Pu Wen From xen-devel-bounces@lists.xenproject.org Wed Mar 25 15:47:15 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 15:47:15 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH8FP-0006Oq-4E; Wed, 25 Mar 2020 15:47:15 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH8FN-0006OY-QU for xen-devel@lists.xenproject.org; Wed, 25 Mar 2020 15:47:13 +0000 X-Inumbo-ID: e3f8b900-6eaf-11ea-92cf-bc764e2007e4 Received: from esa2.hc3370-68.iphmx.com (unknown [216.71.145.153]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id e3f8b900-6eaf-11ea-92cf-bc764e2007e4; Wed, 25 Mar 2020 15:47:11 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=citrix.com; s=securemail; t=1585151232; h=date:from:to:cc:subject:message-id:references: mime-version:in-reply-to; bh=dbTOtT8x2SNiVtOKmCcNhDRhk0OYZTiy2I7AjHtuccI=; b=RmDHGVh+2cHj64u++w5QyPm5K23m0yJicyyA5JjGV8UhA1mV/fmacUgO 7PrOsir1ZjkDekNsUHLmweWqJtcIgPtzJYKsPUxcI2afPj0VshN/kyZuY lasdl7wRNyYslpRbvIQqCkS9O6sf5eRDK9hR2IA65aBi/LvNUhbhmrM4D 4=; Authentication-Results: esa2.hc3370-68.iphmx.com; dkim=none (message not signed) header.i=none; spf=None smtp.pra=roger.pau@citrix.com; spf=Pass smtp.mailfrom=roger.pau@citrix.com; spf=None smtp.helo=postmaster@mail.citrix.com Received-SPF: None (esa2.hc3370-68.iphmx.com: no sender authenticity information available from domain of roger.pau@citrix.com) identity=pra; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="roger.pau@citrix.com"; x-conformance=sidf_compatible Received-SPF: Pass (esa2.hc3370-68.iphmx.com: domain of roger.pau@citrix.com designates 162.221.158.21 as permitted sender) identity=mailfrom; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="roger.pau@citrix.com"; x-conformance=sidf_compatible; x-record-type="v=spf1"; x-record-text="v=spf1 ip4:209.167.231.154 ip4:178.63.86.133 ip4:195.66.111.40/30 ip4:85.115.9.32/28 ip4:199.102.83.4 ip4:192.28.146.160 ip4:192.28.146.107 ip4:216.52.6.88 ip4:216.52.6.188 ip4:162.221.158.21 ip4:162.221.156.83 ip4:168.245.78.127 ~all" Received-SPF: None (esa2.hc3370-68.iphmx.com: no sender authenticity information available from domain of postmaster@mail.citrix.com) identity=helo; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="roger.pau@citrix.com"; x-sender="postmaster@mail.citrix.com"; x-conformance=sidf_compatible IronPort-SDR: kZrplel5J875bLuTyDuYOJJl4zbXErwsm/hiaZVIkGN0A6YdRGHqdVaZgPiSrg5ZX0Ri0JjdLL umVZAXN1X4IkTxxEKdx6BeEazjixL2Y5cVpuEXuLfvOcTbvAq3n0rLyIoTRIg79Q58iU4b/nOY 1At5dHVgz02ssHnnCZWCw0thBL24J7A3HHzBMDSJVd12zFSnRTEGyuM4d+8m0ymZZlC5wqTNWY mkmxJemyMC2ffmlcA7bvqxPYGvtmhLlx+uFhAID+UTfefARNRuritHeRWuot/9mw5GoF/QmWNy TeI= X-SBRS: 2.7 X-MesageID: 14625989 X-Ironport-Server: esa2.hc3370-68.iphmx.com X-Remote-IP: 162.221.158.21 X-Policy: $RELAYED X-IronPort-AV: E=Sophos;i="5.72,304,1580792400"; d="scan'208";a="14625989" Date: Wed, 25 Mar 2020 16:47:02 +0100 From: Roger Pau =?utf-8?B?TW9ubsOp?= To: Tamas K Lengyel Message-ID: <20200325154702.GD28601@Air-de-Roger> References: MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Disposition: inline In-Reply-To: X-ClientProxiedBy: AMSPEX02CAS02.citrite.net (10.69.22.113) To AMSPEX02CL02.citrite.net (10.69.22.126) Subject: Re: [Xen-devel] [PATCH v12 1/3] xen/mem_sharing: VM forking X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Stefano Stabellini , Julien Grall , Wei Liu , Andrew Cooper , Ian Jackson , George Dunlap , Tamas K Lengyel , Jan Beulich , xen-devel@lists.xenproject.org Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Sorry it has taken me a while to get to this.

Oh - now you point this out, the issue is obvious. The above content would make a far more informative commit message.  How about extending the middle paragraph with: "...part of interrupt_shadow, causing svm_get_interrupt_shadow() to mistake the guest having interrupts enabled as being in an interrupt shadow.  This has been observed to cause SeaBIOS to hang on boot." or words to that effect.  The "it definitely breaks a guest" is the most important piece of information here. Do you happen to know call16_int10() was doing, exactly?  We've presumably trapped for emulation to be using svm_get_interrupt_shadow() in the first place. ~Andrew From xen-devel-bounces@lists.xenproject.org Wed Mar 25 16:04:17 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 16:04:17 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH8Vl-0000aw-1v;

Maybe bool for intr_shadow and guest_intr_mask is better? Bool would be better if you're willing to change them. There is a subtle truncation bug with can occur, e.g. foo->intr_shadow = bar & MASK; turns to 0 if MASK isn't the bottom bit, and intr_shadow is not bool. The traditional way to fix this is with !!(bar & MASK), but bools are safer because you can't get it wrong accidentally. Its also fine to drop the resvd entirely.  No need for the field. ~Andrew From xen-devel-bounces@lists.xenproject.org Wed Mar 25 16:04:57 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 16:04:57 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH8WX-0000f5-FM; Wed, 25 Mar 2020 16:04:57 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jH8WW-0000eu-1Y for xen-devel@lists.xenproject.org; Wed, 25 Mar 2020 16:04:56 +0000 X-Inumbo-ID: 5e1446ee-6eb2-11ea-92cf-bc764e2007e4 Received: from mail-ed1-x543.google.com (unknown [2a00:1450:4864:20::543]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 5e1446ee-6eb2-11ea-92cf-bc764e2007e4; Wed, 25 Mar 2020 16:04:55 +0000 (UTC) Received: by mail-ed1-x543.google.com with SMTP id cf14so2997265edb.13 for ; Wed, 25 Mar 2020 09:04:55 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=tklengyel-com.20150623.gappssmtp.com; s=20150623; h=mime-version:references:in-reply-to:from:date:message-id:subject:to :cc:content-transfer-encoding; bh=IftgZPASVT/fQNEb+bZUVOpH4pcqeFi6AZZZQaBKKWk=; b=Cs6qiYvFba3ehxWoxOdVwmxL+BbEBx/O0828nV5q/HImc/5CVmamq4152N51KLjPqb 52Vu0rtp44gRIux3SmDunsDnronyfTtp9WCptGxQ6zoGKMzZ7FJyHwS0+iP1UR0x190D C9Y6pCYOj+XXlDsd0L72zoItkQrBeqP9eyWUePaQJeTl3ur3k40Xxr3DI5psGnDE1G9r Uly2uJtyGl4Zvfhn6iCS37McK65m1WtfM+/pSwkhPBJQJibrbX2GZzUeBA4Wbvh4Hv6l S6ZgOUdTNtHi4n1g5t3xbh4z9zjzLIxzWygg2vU6jRd62pRyr99bxPTDAKEo6qlejZVf PH7Q== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:references:in-reply-to:from:date :message-id:subject:to:cc:content-transfer-encoding; bh=IftgZPASVT/fQNEb+bZUVOpH4pcqeFi6AZZZQaBKKWk=; b=MkcY6zK73BqgZOyIZoWkTRsbcvS2IMs6zkiHOZf5IPLWQu/srUNn4IIXUoL7s8bRsP 02QuDosVahb+8NGQEwMFdmV1AnqSDO9GrXJ232fu7aFS8j5wlevBfsBo5o/VL74ZXZuv 6FtvEaAySsuAzxW5XXnbIRiwenZkBXSyVKGk+Gre8tlRWilIk8KKdU+8pCO/TNjpjRd0 kz/wQ3+P3JRlkvQDFjV/v/0KEYNfXKihProeOHSo9a85GkQiYVXiA13SD/mAxyLQSXtv TcrUEeN9skk9sZP3fT3we+bBOmh0/NTsHrSBkNRbD08OGsLO9lZCw3Aw9glVJdtkwyic b/3w== X-Gm-Message-State: ANhLgQ0U2gFMS6LuBqlQBUPhcgOUPlpGxRFmaTuAa6+kG4GzjoJpbq2h 4czLybLXXJAzJdIMGoOmvNngTJsI2rI= X-Google-Smtp-Source: ADFU+vsdx0/aPajwl/OTwSHxkjD1zn6spZywmK8TnO9URjr7aqETlqmRF1gYGEQ1ZOvIpz/Eb6qmMQ== X-Received: by 2002:a17:906:3ec5:: with SMTP id d5mr3918324ejj.106.1585152294374; Wed, 25 Mar 2020 09:04:54 -0700 (PDT) Received: from mail-wr1-f52.google.com (mail-wr1-f52.google.com.

Thoughts? FWIW, I will also need the offset for liveupdate. I have used (unsigned long)v->vcpu_info & ~PAGE_MASK so far but this is not really pretty.

A macro sounds like a good way to go, no need for an extra field if we can calculate it based on the currently existing one.

PAGE_OFFSET(ptr) ((unsigned long)(ptr) & ~PAGE_MASK) Anyway, I am happy either way.

I think using: (vaddr_t)v->vcpu_info & ~PAGE_MASK is acceptable, but that would require adding a vaddr_t typedef to x86. Adding a macro to do so would be OK by me, maybe PAGE_OFFSET or some such? > So I am all for either a new field or a macro hiding this uglyness. Macro would be better IMO, as it's redundant to store the offset when we can obtain it from an existing field. Thanks, Roger.

Should we stuff this into xen/sched.h or asm/page.h? page.h would be better, albeit you will have to duplicate it for x86 and Arm. There's xen/pfn.h which is not arch specific, but feels a bit weird to place it there. Thanks, Roger.

So I would like the new header to contain the type definitions and any wrappers that would turn 'generic' operations safe. I am not entirely sure yet how to formalize the rules in the header.

Even on top of WB/WP mappings, it needs to have WC properties, knock aliasing lines out of the cache, and ending up as a bus transaction. Also, I'm not convinced the current chunking algorithm for qemu which repeatedly subdivides down to 1, is compatible with the misaligned behaviour described, guaranteeing a split of two. ~Andrew From xen-devel-bounces@lists.xenproject.org Wed Mar 25 21:13:09 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 25 Mar 2020 21:13:09 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHDKZ-0001HR-QG; Wed, 25 Mar 2020 21:12:55 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHDKZ-0001HM-3X for xen-devel@lists.xenproject.org; Wed, 25 Mar 2020 21:12:55 +0000 X-Inumbo-ID: 63f2f5a8-6edd-11ea-bec1-bc764e2007e4 Received: from esa2.hc3370-68.iphmx.com (unknown [216.71.145.153]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 63f2f5a8-6edd-11ea-bec1-bc764e2007e4; Wed, 25 Mar 2020 21:12:53 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=citrix.com; s=securemail; t=1585170773; h=subject:to:cc:references:from:message-id:date: mime-version:in-reply-to:content-transfer-encoding; bh=1nIX7ENOm2rHbhuxBW4YviYHAV1xyEguMSyaUkKLPMw=; b=QhznDHSlyd6B91q2W7b9ZSK+zmbiLF/M0QbWHD+JnQUqJFUonsjVJQ41 ruRMmOlm6/PxSBAWKCKwmLqeynshesB5QleZRKl/zGgplZWxswyTzrNWz g9XpMd0a39jLeuisb13Gkk+8kmEOvAT6HH5zaXB14IeZ4EcevInyLHmB1 Q=; Authentication-Results: esa2.hc3370-68.iphmx.com; dkim=none (message not signed) header.i=none; spf=None smtp.pra=andrew.cooper3@citrix.com; spf=Pass smtp.mailfrom=Andrew.Cooper3@citrix.com; spf=None smtp.helo=postmaster@mail.citrix.com Received-SPF: None (esa2.hc3370-68.iphmx.com: no sender authenticity information available from domain of andrew.cooper3@citrix.com) identity=pra; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="andrew.cooper3@citrix.com"; x-conformance=sidf_compatible Received-SPF: Pass (esa2.hc3370-68.iphmx.com: domain of Andrew.Cooper3@citrix.com designates 162.221.158.21 as permitted sender) identity=mailfrom; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="Andrew.Cooper3@citrix.com"; x-conformance=sidf_compatible; x-record-type="v=spf1"; x-record-text="v=spf1 ip4:209.167.231.154 ip4:178.63.86.133 ip4:195.66.111.40/30 ip4:85.115.9.32/28 ip4:199.102.83.4 ip4:192.28.146.160 ip4:192.28.146.107 ip4:216.52.6.88 ip4:216.52.6.188 ip4:162.221.158.21 ip4:162.221.156.83 ip4:168.245.78.127 ~all" Received-SPF: None (esa2.hc3370-68.iphmx.com: no sender authenticity information available from domain of postmaster@mail.citrix.com) identity=helo; client-ip=162.221.158.21; receiver=esa2.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="postmaster@mail.citrix.com"; x-conformance=sidf_compatible IronPort-SDR: 1rQuVE/lWBzKWQkfft3AlPK0RX0y6iNtv1guBhq41Id1AlpdAPq44ZFazmbwxPkm2+v3FWOUPf 2cMe9HTNC3s6868XlNEXvd9zYn4Jhhtd5lYOVGRMfecS58cdLMm1N4C4ts7vw9fGZvtlpO19Qp 9z/01fsoF3GQW26rVUqPW2UDOG8syTI4fBneskA3JVMIbNhCtqwNyAAdq3eRfvoM/11JU53tXl Rj9vSr5EoL73+QB3UU5Md+FWmHnbFEp3j2Y2AMydqc2+QFV3fc+KhrkqlwmJjB9/WzB1K894rq elE= X-SBRS: 2.7 X-MesageID: 14648121 X-Ironport-Server: esa2.hc3370-68.iphmx.com X-Remote-IP: 162.221.158.21 X-Policy: $RELAYED X-IronPort-AV: E=Sophos;i="5.72,305,1580792400"; d="scan'208";a="14648121" To: Jan Beulich , "xen-devel@lists.xenproject.org" References: <6fa81b4d-528d-5c33-50c5-a18396b4383a@suse.com> <2c83b876-6fd8-1315-3b28-b45e877187aa@suse.com> From: Andrew Cooper Message-ID: <7147e3a1-b237-7a2b-d623-b364704d0096@citrix.com> Date: Wed, 25 Mar 2020 21:12:48 +0000 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Thunderbird/68.4.1 MIME-Version: 1.0 In-Reply-To: <2c83b876-6fd8-1315-3b28-b45e877187aa@suse.com> Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Content-Language: en-GB X-ClientProxiedBy: AMSPEX02CAS02.citrite.net (10.69.22.113) To AMSPEX02CL02.citrite.net (10.69.22.126) Subject: Re: [Xen-devel] [PATCH v5 03/10] x86: determine HAVE_AS_* just once X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Stefano Stabellini , Julien Grall , Wei Liu , Ian Jackson , George Dunlap , Anthony PERARD , Roger Pau Monne Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" On 24/03/2020 12:33, Jan Beulich wrote: > With the exception of HAVE_AS_QUOTED_SYM, populate the results into a > generated header instead of (at least once per [sub]directory) into > CFLAGS.

Mar 24 10:56:22 2020 +0100 x86/mce: correct the machine check vendor for Hygon Currently the xl dmesg output on Hygon platforms will be "(XEN) CPU0: AMD Fam18h machine check reporting enabled", which is misleading as AMD does not have family 18h (Hygon negotiated with AMD to confirm that only Hygon has family 18h). To correct this, add Hygon machine check type and vendor string.

Signed-off-by: Hongyan Xia Reviewed-by: Jan Beulich commit f10df652c78cbdd0c25e93767baad55b022af5be Author: David Woodhouse Date: Tue Mar 24 10:43:51 2020 +0100 build: add -MP to CFLAGS along with -MMD This causes gcc (yes, and clang) to emit phony targets for each dependency. This means that when a header file is deleted, the C files which *used* to include it will no longer stop building with bogus out-of-date dependencies like this: make[5]: *** No rule to make target '/home/dwmw2/git/xen/xen/include/asm/hvm/svm/amd-iommu-proto.h', needed by 'p2m.o'. Stop. Based on -MP post-dating -MP by many years it is assumed that the behavior of -MP isn't the defualt just out of extreme caution. We're sufficiently convinced that there are no undue side effects of this.

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Neither is the case, I guess: There simply is no smp_wmb__before_atomic() in Linux, and if we want to follow their model we shouldn't have one either.

Right, using unsigned long is indeed fine, but I also agree with Tamas that it's slightly ugly and hence wanted to provide a 'cleaner' suggestion. Roger.

For x86 smp_wmb() is actually only very slightly too strong - it expands to just barrier(), after all. So overall perhaps that's the better choice here (with a suitable comment)?

Any ideas? Well, if the header was just for the typesafe types, it could be renamed (to e.g. mm-typesafe.h) and be left without any respective comment. The issue I've mentioned arises if, with its currently suggested name, further types get added. In such a case perhaps it could be "type definitions and their immediate accessors, involving no other non-trivial types"?

The negation of an unsigned int is still an unsigned int, and hence e.g. -1U (which might result here) is really 0xFFFFFFFF rather than -1L / -1UL as intended. Whereas with mfn_sub() the conversion to unsigned long of the (positive) value to subtract would occur as part of evaluating function arguments, and the resulting subtraction would then be correct. >>> @@ -584,21 +584,21 @@ static unsigned long init_node_heap(int node, unsigned long mfn, >>>           needed = 0; >>>       } >>>       else if ( *use_tail && nr >= needed && >>> -              arch_mfn_in_directmap(mfn + nr) && >>> +              arch_mfn_in_directmap(mfn_x(mfn_add(mfn, nr))) && >>>                 (!xenheap_bits || >>> -               !((mfn + nr - 1) >> (xenheap_bits - PAGE_SHIFT))) ) >>> +               !((mfn_x(mfn) + nr - 1) >> (xenheap_bits - PAGE_SHIFT))) ) >> >> May I suggest consistency here: This one uses +, while ... >> >>>       { >>> -        _heap[node] = mfn_to_virt(mfn + nr - needed); >>> -        avail[node] = mfn_to_virt(mfn + nr - 1) + >>> +        _heap[node] = mfn_to_virt(mfn_add(mfn, nr - needed)); >>> +        avail[node] = mfn_to_virt(mfn_add(mfn, nr - 1)) + >>>                         PAGE_SIZE - sizeof(**avail) * NR_ZONES; >>>       } >>>       else if ( nr >= needed && >>> -              arch_mfn_in_directmap(mfn + needed) && >>> +              arch_mfn_in_directmap(mfn_x(mfn_add(mfn, needed))) && >> >> ... this one uses mfn_add() despite the mfn_x() around it, and ... > > So the reason I used mfn_x(mfn_add(mfn, needed)) here is I plan > to convert arch_mfn_in_directmap() to use typesafe soon.

I too have been wondering, and wouldn't mind their introduction (plus mfn_le / mfn_ge perhaps). But it'll truly help you here anyway only once the function parameter is also mfn_t.

I think printing a debug message might be helpful, not so much as for the importance of failing to copy the runstate area, but it could signal that something went wrong, anyway I don't have such a strong opinion. Just to confirm, __copy_to_guest will cause the forked domain memory to be populated and the whole page to be copied over right?

It is raising sched softirqs without any real need and it requires tasklets for rcu_barrier(), which interacts badly with core scheduling. This small series repairs those issues. Additionally some ASSERT()s are added for verification of sane rcu handling. In order to avoid those triggering right away the obvious violations are fixed. This includes making rcu locking functions type safe.

Add ASSERT()s in debug builds in order to catch any violations. For that purpose modify rcu_read_[un]lock() to use a dedicated percpu counter additional to preempt_[en|dis]able() as this enables to test that condition in __do_softirq() (ASSERT_NOT_IN_ATOMIC() is not usable there due to __cpu_up() calling process_pending_softirqs() while holding the cpu hotplug lock).

As stop_machine_run() is using tasklets this requires scheduling of idle vcpus on all cpus imposing the need to call rcu_barrier() on idle cpus only in case of core scheduling being active, as otherwise a scheduling deadlock would occur. There is no need at all to do the syncing of the cpus in tasklets, as rcu activity is started in __do_softirq() called whenever softirq activity is allowed. So rcu_barrier() can easily be modified to use softirq for synchronization of the cpus no longer requiring any scheduling activity. As there already is a rcu softirq reuse that for the synchronization. Remove the barrier element from struct rcu_data as it isn't used. Finally switch rcu_barrier() to return void as it now can never fail.

First, original code requires only one > __vmwrite but now needs two writes and one read for Ack-on-exit > is set. Can we optimize to sustain the original behavior? I think I can manage to do a single write by using a global status variable initialized to 0 and only do the vmwrite if the value is != 0 by the end of the function. > Second, > although I didn't come up a case where always updating RVI (w/ > pending interrupt) may bring some bad effect, it is anyway safer > to put the whole logic within the check of vmexit reason and intr > source. I also considered this and decided there was no harm in always updating RVI if there's a pending interrupt, it could even prevent a future VMEXIT to update RVI AFAICT? If you prefer I can return early from the function if reason != EXIT_REASON_EXTERNAL_INTERRUPT. Thanks, Roger.

Taking care of these two will be a significant amount of (re-)work of the HVM emulation layer. I'll see if I can come up with time and ideas on how to do this.

No - it will only check the bitmap when there's a virtual vmexit (which is where nvmx_update_apicv gets called), not on every vmentry. I can try to do this conditionally on whether GUEST_INTR_STATUS is actually changed. Thanks, Roger.

There are two reasons for this. First, the task does not follow the x86 convention that its stack starts at the offset right below saved pt_regs. It allows the unwinder to easily detect the end of the stack and verify it. Second, startup_xen() function does not store the return address before jumping to xen_start_kernel() which confuses the unwinder. Amend both issues by moving the starting point of initial stack in startup_xen() and storing the return address before the jump, which is exactly what call instruction does.

After it is woken up, the idle task starts in cpu_bringup_and_idle() function and its stack starts at the offset right below pt_regs. The unwinder correctly detects the end of stack there but it is confused by NULL return address in the last frame. Introduce a wrapper in assembly, which just calls cpu_bringup_and_idle(). The return address is thus pushed on the stack and the wrapper contains the annotation hint for the unwinder regarding the stack state.

For large guests with lots of vcpus this is not enough, as e.g. the Linux kernel uses 7 event channels per vcpu, limiting the guest to about 140 vcpus. Instead of requiring to specify the allowed number of event channels via the "event_channels" domain config option, make the default depend on the maximum number of vcpus of the guest. In order not to regress current configs use 1023 as the minimum default setting.

I don't think any particular guest OS should "dictate" the default here. What if another OS (or even a future version of Linux) requires more than 8?

And with HVM guests being limited to 128 cpus anyway, this problem is more relevant for PV guests, limiting the available options for guest OS's. You can always specify a larger value in the guest config after all.

Xenstore stubdom is unlimited like dom0, BTW.

We might need one small change for this to happen, it is to add a comment in .config which display the output of `$(CC) --version | head -1`. Simple :-). If the output of `$(CC) --version` changes, kconfig will run again. That would be enough to detect tool chain updates, right? Have a look at "include/config/auto.conf.cmd" to find out how kconfig is forced to run again. I'll prepare a patch. -- Anthony PERARD From xen-devel-bounces@lists.xenproject.org Thu Mar 26 13:47:14 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Thu, 26 Mar 2020 13:47:14 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHSqn-00055I-Ad; Thu, 26 Mar 2020 13:47:13 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHSqm-000558-2f for xen-devel@lists.xenproject.org; Thu, 26 Mar 2020 13:47:12 +0000 X-Inumbo-ID: 4480725b-6f68-11ea-87eb-12813bfff9fa Received: from spam1.hygon.cn (unknown [110.188.70.11]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id 4480725b-6f68-11ea-87eb-12813bfff9fa; Thu, 26 Mar 2020 13:47:04 +0000 (UTC) Received: from MK-DB.hygon.cn ([172.23.18.60]) by spam1.hygon.cn with ESMTP id 02QDk5aL025813; Thu, 26 Mar 2020 21:46:10 +0800 (GMT-8) (envelope-from puwen@hygon.cn) Received: from cncheex01.Hygon.cn ([172.23.18.10]) by MK-DB.hygon.cn with ESMTP id 02QDjujZ047625; Thu, 26 Mar 2020 21:46:02 +0800 (GMT-8) (envelope-from puwen@hygon.cn) Received: from localhost.localdomain (172.23.18.44) by cncheex01.Hygon.cn (172.23.18.10) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256) id 15.1.1466.3; Thu, 26 Mar 2020 21:45:35 +0800 From: Pu Wen To: Date: Thu, 26 Mar 2020 21:44:30 +0800 Message-ID: <1585230270-24178-1-git-send-email-puwen@hygon.cn> X-Mailer: git-send-email 2.7.4 MIME-Version: 1.0 Content-Type: text/plain X-Originating-IP: [172.23.18.44] X-ClientProxiedBy: cncheex01.Hygon.cn (172.23.18.10) To cncheex01.Hygon.cn (172.23.18.10) X-MAIL: spam1.hygon.cn 02QDk5aL025813 X-DNSRBL: Subject: [Xen-devel] [PATCH v3] SVM: Add union intstat_t for offset 68h in vmcb struct X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Pu Wen , =?UTF-8?q?Roger=20Pau=20Monn=C3=A9?= , Wei Liu , Jan Beulich , Andrew Cooper Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" According to chapter "Appendix B Layout of VMCB" in the new version (v3.32) AMD64 APM[1], bit 1 of the VMCB offset 68h is defined as GUEST_INTERRUPT_MASK. In current xen codes, it use whole u64 interrupt_shadow to setup interrupt shadow, which will misuse other bit in VMCB offset 68h as part of interrupt_shadow, causing svm_get_interrupt_shadow() to mistake the guest having interrupts enabled as being in an interrupt shadow. This has been observed to cause SeaBIOS to hang on boot. Add union intstat_t for VMCB offset 68h and fix codes to only use bit 0 as intr_shadow according to the new APM description.

Split the field, adding definitions for a few other bits at the same time. To be able to generate accessors for bitfields, VMCB_ACCESSORS() needs the type part broken out, as typeof() can't be applied to bitfields. Unfortunately this means specification of the same type in two distinct places.

Simple :-). > If the output of `$(CC) --version` changes, kconfig will run again. That > would be enough to detect tool chain updates, right? I'm afraid it's not that simple: For one I'm not sure that line would indeed change when a distro issues a gcc update. Even the minor version may not change in this case; recall as an example the backport of the compiler support backing INDIRECT_THUNK. And then gcc isn't the tool chain - it may well be that e.g. gas gets updated (supporting new insns or directives) without gcc getting touched at all. Plus finally I don't think a comment like you suggest would do - while processing it kconfig would find that $(CC) gets used, but aiui it would then record just $(CC) as needing tracking, not the output of the command. But maybe I'm lacking some further detail here. > Have a look at "include/config/auto.conf.cmd" to find out how kconfig is > forced to run again. Oh, that's good to know. Thanks for the pointer.

These old microcode blobs are still around, including in some versions of microcode.dat.  By dropping the ability to recognise them as legitimate, we'd break the logic to search through a container of multiple blobs to find the one which matches. ~Andrew From xen-devel-bounces@lists.xenproject.org Thu Mar 26 14:36:31 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Thu, 26 Mar 2020 14:36:31 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHTcV-0001Tm-2i; Thu, 26 Mar 2020 14:36:31 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHTcT-0001TS-5y for xen-devel@lists.xenproject.org; Thu, 26 Mar 2020 14:36:29 +0000 X-Inumbo-ID: 2cd45e30-6f6f-11ea-87fa-12813bfff9fa Received: from esa3.hc3370-68.iphmx.com (unknown [216.71.145.155]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id 2cd45e30-6f6f-11ea-87fa-12813bfff9fa; Thu, 26 Mar 2020 14:36:27 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=citrix.com; s=securemail; t=1585233388; h=subject:to:cc:references:from:message-id:date: mime-version:in-reply-to:content-transfer-encoding; bh=IbUOCqRBo5Kd57JOVwHpMirKN2kT0Jk/jQgsD8THMgw=; b=Me+FXZmfBsRL+L58sA40G+iOcdvXEuGXO1dBlKIYLtPx56GWIFGaejmn EPZo/jTbuP7NieAuNDmcd1OPxqOY3lPeqp61G6CviWZYrgyrICQGjeZot j0cj66ybqO9W1E+Rig7mTc2rffHo1iWCNPWEiobgYIjuA11uG8bBqTaYt o=; Authentication-Results: esa3.hc3370-68.iphmx.com; dkim=none (message not signed) header.i=none; spf=None smtp.pra=andrew.cooper3@citrix.com; spf=Pass smtp.mailfrom=Andrew.Cooper3@citrix.com; spf=None smtp.helo=postmaster@mail.citrix.com Received-SPF: None (esa3.hc3370-68.iphmx.com: no sender authenticity information available from domain of andrew.cooper3@citrix.com) identity=pra; client-ip=162.221.158.21; receiver=esa3.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="andrew.cooper3@citrix.com"; x-conformance=sidf_compatible Received-SPF: Pass (esa3.hc3370-68.iphmx.com: domain of Andrew.Cooper3@citrix.com designates 162.221.158.21 as permitted sender) identity=mailfrom; client-ip=162.221.158.21; receiver=esa3.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="Andrew.Cooper3@citrix.com"; x-conformance=sidf_compatible; x-record-type="v=spf1"; x-record-text="v=spf1 ip4:209.167.231.154 ip4:178.63.86.133 ip4:195.66.111.40/30 ip4:85.115.9.32/28 ip4:199.102.83.4 ip4:192.28.146.160 ip4:192.28.146.107 ip4:216.52.6.88 ip4:216.52.6.188 ip4:162.221.158.21 ip4:162.221.156.83 ip4:168.245.78.127 ~all" Received-SPF: None (esa3.hc3370-68.iphmx.com: no sender authenticity information available from domain of postmaster@mail.citrix.com) identity=helo; client-ip=162.221.158.21; receiver=esa3.hc3370-68.iphmx.com; envelope-from="Andrew.Cooper3@citrix.com"; x-sender="postmaster@mail.citrix.com"; x-conformance=sidf_compatible IronPort-SDR: EMQhGZcDHjFp4aLz/krKbsnl8nvj/mePf6U0zdvJT4R2+Z1aeEJNC/uaax3qm8m9q20iM+XyVv 8ie2SpFATayGTujDTnFHZdphoyUILeB7sUg17bdgCSWx2i1ZW6/hqauPboKrSxThFpYH6JYCqt oMtODy7MUwxxV+rRsKNhmxJYtecOiDfPBS3PeOxWyridUS3rTk+hY6vitPfhWlr2DFQIKYVrK5 TWOFPc0PGOX2Erz699Zqc2I6m4m4ecxQMYit5j/6VTK+BlJ9WitMUY43CChJU4BmAz6/HJtDiQ mso= X-SBRS: 2.7 X-MesageID: 14673135 X-Ironport-Server: esa3.hc3370-68.iphmx.com X-Remote-IP: 162.221.158.21 X-Policy: $RELAYED X-IronPort-AV: E=Sophos;i="5.72,308,1580792400"; d="scan'208";a="14673135" To: Jan Beulich References: <20200323101724.15655-1-andrew.cooper3@citrix.com> <20200323101724.15655-6-andrew.cooper3@citrix.com> From: Andrew Cooper Message-ID: <9e1238ea-3ad2-a529-e88e-51c6f607f45d@citrix.com> Date: Thu, 26 Mar 2020 14:36:23 +0000 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Thunderbird/68.4.1 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit Content-Language: en-GB X-ClientProxiedBy: AMSPEX02CAS02.citrite.net (10.69.22.113) To AMSPEX02CL02.citrite.net (10.69.22.126) Subject: Re: [Xen-devel] [PATCH 5/7] x86/ucode/intel: Clean up microcode_update_match() X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Xen-devel , Wei Liu , =?UTF-8?Q?Roger_Pau_Monn=c3=a9?= Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" On 25/03/2020 13:51, Jan Beulich wrote: > On 23.03.2020 11:17, Andrew Cooper wrote: >> Implement a new get_ext_sigtable() helper to abstract the logic for >> identifying whether an extended signature table exists.

The best solution is to make the heap scalable instead of a global lock, but that is not going to be trivial. Of course, another solution is to keep the domctl lock dropped in domain_kill() but have another domain_kill lock so that competing domain_kill()s will try to take that lock and back off with hypercall continuation. But this is kind of hacky (we introduce a lock to reduce spinlock contention elsewhere), which is probably not a solution but a workaround. Seeing the dramatic increase from 6 to 29 minutes in concurrent guest destruction, I wonder if the benefit of that commit can outweigh this negative though.

On a perhaps tangential note, what (if anything) are you plans regarding backport here? These defines are ok for a transitional period across a series (and probably means I'll need to get the AMD side ready to be committed at the same time), but I don't think we'd want them in the code for the longterm. I personally wasn't overly concerned about backports, but if you are, we should probably take this into consideration for the fixes. ~Andrew From xen-devel-bounces@lists.xenproject.org Thu Mar 26 14:52:39 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Thu, 26 Mar 2020 14:52:39 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHTs6-0003aI-Vf; Thu, 26 Mar 2020 14:52:38 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHTs6-0003aD-Gb for xen-devel@lists.xenproject.org; Thu, 26 Mar 2020 14:52:38 +0000 X-Inumbo-ID: 6f2e591e-6f71-11ea-bec1-bc764e2007e4 Received: from mx2.suse.de (unknown [195.135.220.15]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 6f2e591e-6f71-11ea-bec1-bc764e2007e4; Thu, 26 Mar 2020 14:52:38 +0000 (UTC) X-Virus-Scanned: by amavisd-new at test-mx.suse.de Received: from relay2.suse.de (unknown [195.135.220.254]) by mx2.suse.de (Postfix) with ESMTP id 09B07B1DC; Thu, 26 Mar 2020 14:52:37 +0000 (UTC) To: Tamas K Lengyel References: <46457bd6e877abe12a8c005c23f0f1aab13afd24.1584981438.git.tamas.lengyel@intel.com> <3f0fd837-bee6-3a68-8db3-1a99b97aac9e@suse.com> From: Jan Beulich Message-ID: <9c7d7147-cb83-5e91-38b7-906a81582ac4@suse.com> Date: Thu, 26 Mar 2020 15:52:35 +0100 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:68.0) Gecko/20100101 Thunderbird/68.6.0 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: 7bit Subject: Re: [Xen-devel] [PATCH v12 2/3] x86/mem_sharing: reset a fork X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Julien Grall , Stefano Stabellini , Tamas K Lengyel , Wei Liu , Andrew Cooper , Ian Jackson , George Dunlap , Xen-devel , =?UTF-8?Q?Roger_Pau_Monn=c3=a9?= Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" On 26.03.2020 15:48, Tamas K Lengyel wrote: > On Thu, Mar 26, 2020 at 4:17 AM Jan Beulich wrote: >> >> On 23.03.2020 18:04, Tamas K Lengyel wrote: >>> +static int mem_sharing_fork_reset(struct domain *d, struct domain *pd) >>> +{ >>> + int rc; >>> + struct p2m_domain *p2m = p2m_get_hostp2m(d); >>> + struct page_info *page, *tmp; >>> + >>> + spin_lock(&d->page_alloc_lock); >>> + domain_pause(d); >> >> Why do you take the lock first? > > No particular reason - does the order matter? I think you'd better avoid holding a lock for extended periods of time. And what's perhaps worse, what if a vCPU of the domain sits in Xen trying to acquire this lock - you'd deadlock trying to pause the domain then.

Till now I didn't see a strong reason why backporting might be needed (or even just wanted). If you think there is one, arranging for backport material to come first would of course be nice. And indeed, the #define-s you mention are meant to be there just to limit the churn of this immediate patch; I'd be happy to see them go away in another patch immediately after.

The net result of of patch 5 is three adjacent helpers, which are the only code which use the fields themselves.

This series aims to fix the regression, and should unblock several osstest branches. The following report is from osstest with this series applied: http://logs.test-lab.xenproject.org/osstest/logs/149051/ Note the last patch (4/4) is the one that actually fixes the issue. Xen will always use the Ack on exit feature so patches 2/4 and 3/4 don't change the functionality when running a nested Xen, as it always requires SVI to be updated. Thanks, Roger.

Updating RVI however is not tied to the Ack on exit feature, as it signals the next vector to be injected, and hence should always be updated to the next pending vector, regardless of whether Ack on exit is enabled. When not using the Ack on exit feature preserve the previous vector in SVI, so that it's not lost when RVI is updated to contain the pending vector to inject. Signed-off-by: Roger Pau Monné --- Changes since v2: - Return early if the exit reason != EXTERNAL_INTERRUPT. - Reduce the number of vmwrites by accumulating the changes to a local variable which is flushed at the end of the function. - Attempt to preserve the exiting SVI if Ack on exit is not enabled. --- xen/arch/x86/hvm/vmx/vvmx.c | 33 ++++++++++++++++++++++++--------- 1 file changed, 24 insertions(+), 9 deletions(-) diff --git a/xen/arch/x86/hvm/vmx/vvmx.c b/xen/arch/x86/hvm/vmx/vvmx.c index 1753005c91..39fb553590 100644 --- a/xen/arch/x86/hvm/vmx/vvmx.c +++ b/xen/arch/x86/hvm/vmx/vvmx.c @@ -1384,28 +1384,43 @@ static void nvmx_update_apicv(struct vcpu *v) struct nestedvmx *nvmx = &vcpu_2_nvmx(v);

Hence it is even more so important that the patch introducing the new helper(s) first gets sorted. Should there be further patches in this series with this same interaction issue, I won't point it out again and may not respond at all if I see no other issues.

The problem is that we are still in the process of forking the VM, so mem_sharing_is_fork is not yet true, since we haven't finished the process yet completely. So what I'll do is set the parent pointer early which will allow memory to be populated from the parent. If there is an error during the fork operation the fork domain is getting destroyed by the toolstack anyway so we don't have to worry about unwinding a half-way completed fork.

My vague recollection is that the issue was the tool stack as > a whole stalling for far too long in particular when destroying very > large guests. I too only have a vague memory of the issue but do recall shutting down large guests (e.g. 500GB) taking a long time and blocking other toolstack operations. I haven't checked on the behavior in quite some time though. > One important aspect not discussed in the commit message > at all is that holding the domctl lock block basically _all_ tool stack > operations (including e.g. creation of new guests), whereas the new > issue attempted to be addressed is limited to just domain cleanup. I more vaguely recall shutting down the host taking a *long* time when dom0 had large amounts of memory, e.g. when it had all host memory (no dom0_mem= setting and autoballooning enabled).

But we are currently not doing anything with such value, so let's get rid of it and make the function void. As an anecdote, that's pretty much the same that happened in Linux as, since commit 807e9bc8e2fe6 ("x86/CPU: Move cpu_detect_cache_sizes() into init_intel_cacheinfo()") the function is void there too.

Since 12509bbeb9e ("rwlocks: call preempt_disable() when taking a rwlock") preemption is disabled after taking cpu_maps which will block RCU callback processing inside rcu_barrier itself. This will result in all system hang on boot after 540d4d60378 ("cpu: sync any remaining RCU callbacks before CPU up/down").

It turns out we also need to take the recursive lock here since we'll free the pages. Fixed now and everything works as expected.

Paul Durrant Date: Tue Mar 24 17:40:50 2020 +0100 mm: add 'is_special_page' inline function... ... to cover xenheap and PGC_extra pages. PGC_extra pages are intended to hold data structures that are associated with a domain and may be mapped by that domain. They should not be treated as 'normal' guest pages (i.e. RAM or page tables). Hence, in many cases where code currently tests is_xen_heap_page() it should also check for the PGC_extra bit in 'count_info'. This patch therefore defines is_special_page() to cover both cases and converts tests of is_xen_heap_page() (or open coded tests of PGC_xen_heap) to is_special_page() where the page is assigned to a domain.

This avoids them getting confused with 'normal' domheap pages where the domain's page_list is walked. A new dump loop is also added to dump_pageframe_info() to unconditionally dump the 'extra page list'.

In case the added cpu is not the last sibling to be onlined this test is wrong as it only checks for all online siblings to be free. The test should include the check for the number of siblings having reached the scheduling granularity of cpupool0, too.

This means that when a header file is deleted, the C files which *used* to include it will no longer stop building with bogus out-of-date dependencies like this: make[5]: *** No rule to make target '/home/dwmw2/git/xen/xen/include/asm/hvm/svm/amd-iommu-proto.h', needed by 'p2m.o'. Stop. Based on -MP post-dating -MP by many years it is assumed that the behavior of -MP isn't the defualt just out of extreme caution. We're sufficiently convinced that there are no undue side effects of this.

xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: xen-devel@lists.xenproject.org, Peng Fan , Stefano Stabellini , Stefano Stabellini , Wei Xu Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" This is a simple implementation of GICD_ICACTIVER / GICD_ISACTIVER reads. It doesn't take into account the latest state of interrupts on other vCPUs. Only the current vCPU is up-to-date. A full solution is not possible because it would require synchronization among all vCPUs, which would be very expensive in terms or latency. Signed-off-by: Stefano Stabellini CC: Wei Xu CC: Peng Fan --- Changes in v2: - improve commit message - do not invert result - use 1U - use common patter with vgic_rank_offset - move implementation into a separate function called vgic_isactiver - add vgic2 implementation - tested on vgic2 by hacking the Linux gicv2 driver --- xen/arch/arm/vgic-v2.c | 13 +++++++++++-- xen/arch/arm/vgic-v3.c | 15 ++++++++++++--- xen/arch/arm/vgic.c | 20 ++++++++++++++++++++ xen/include/asm-arm/vgic.h | 1 + 4 files changed, 44 insertions(+), 5 deletions(-) diff --git a/xen/arch/arm/vgic-v2.c b/xen/arch/arm/vgic-v2.c index 64b141fea5..454408d11d 100644 --- a/xen/arch/arm/vgic-v2.c +++ b/xen/arch/arm/vgic-v2.c @@ -245,10 +245,19 @@ static int vgic_v2_distr_mmio_read(struct vcpu *v, mmio_info_t *info, case VRANGE32(GICD_ICPENDR, GICD_ICPENDRN): goto read_as_zero;

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Assuming you meant intstat -> intstate and int_stat -> int_state, but in any event I don't think you've actually made the change while committing.

Igor, are you perhaps running without "rcu: add assertions to debug build"? I think this actually fixes what you describe. Without it rcu_barrier(), in its second loop, calling process_pending_softirqs(), would cause the RCU softirq to not be invoked anymore with preemption disabled. Of course the title of this change doesn't reflect this at all. Jürgen, as an aside, while looking at the code again, I think the comment near the end of process_pending_softirqs() would now rather belong at its very beginning; should have spotted this while reviewing.

Add the apt-transport-https package to the x86 Debian containers that use the LLVM repos, in order to support the https transport method. Note that on Arm we only test with gcc, so don't add the package for the Debian Arm container. This fixes the following error seen on the QEMU smoke tests: E: The method driver /usr/lib/apt/methods/https could not be found.

Loading occurs entirely within the boundary of a single WRMSR instruction. Its certainly not a BUG()-worthy condition. Xen has legitimate reasons to not want interrupts enabled at this point, but that is to do with organising the system rendezvous. As these are private low level helpers invoked only from the microcode core logic, forgo the check entirely. While dropping system.h, clean up the processor.h include which was an oversight in the previous header cleanup. Signed-off-by: Andrew Cooper --- CC: Jan Beulich CC: Wei Liu CC: Roger Pau Monné An ASSERT() would be one option, but I'd prefer to remove the include. --- xen/arch/x86/cpu/microcode/amd.c | 4 ----

Rework it to take struct microcode_patch *, which in turn requires microcode_update_match()'s type to be altered. No functional change - compiled binary is identical.

As part of this, rename microcode_intel.bits to data and change its type so it can be usefully used in combination with the datasize header field. Also, replace the sigmatch() macro with a static inline with a more useful API, and an explanation of why it is safe to drop one of the previous conditionals. No practical change in behaviour.

Furthermore, the length checking is only safe from overflow in 64bit builds. Delete get_next_ucode_from_buffer() and alter the purpose of the saved variable to simply point somewhere in buf until we're ready to return. This is only a modest reduction in absolute code size (-144), but avoids making memory allocations for every blob in the container.

This is wasteful. Fixing this is complicated because the common microcode_free_patch() code is responsible for freeing struct microcode_patch, despite this being asymmetric with how it is allocated. Make struct microcode_patch fully opaque to the common logic. This involves moving the responsibility for freeing struct microcode_patch fully into the free_patch() hook. In each vendor logic, use some temporary ifdef-ary (cleaned up in subsequent changes) to reduce the churn as much as possible, and forgo allocating the intermediate pointer in cpu_request_microcode().

The gratuitous memory allocation fixes would be the most compelling (and even then, not massively so), but they're sufficiently interlaced with the rest of the cleanup that I wasn't expecting backports to be a pleasant idea. ~Andrew From xen-devel-bounces@lists.xenproject.org Fri Mar 27 12:44:30 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Fri, 27 Mar 2020 12:44:30 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHoLa-0000AV-HP; Fri, 27 Mar 2020 12:44:26 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHoLZ-0000AQ-0h for xen-devel@lists.xenproject.org; Fri, 27 Mar 2020 12:44:25 +0000 X-Inumbo-ID: afaf8abe-7028-11ea-896b-12813bfff9fa Received: from mx2.suse.de (unknown [195.135.220.15]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id afaf8abe-7028-11ea-896b-12813bfff9fa; Fri, 27 Mar 2020 12:44:24 +0000 (UTC) X-Virus-Scanned: by amavisd-new at test-mx.suse.de Received: from relay2.suse.de (unknown [195.135.220.254]) by mx2.suse.de (Postfix) with ESMTP id 2DB20AC5B; Fri, 27 Mar 2020 12:44:23 +0000 (UTC) To: julien@xen.org References: <20200322161418.31606-1-julien@xen.org> <20200322161418.31606-15-julien@xen.org> From: Jan Beulich Message-ID: <6e078fa4-8d38-e6bc-27c2-d1e91d0b6d3c@suse.com> Date: Fri, 27 Mar 2020 13:44:22 +0100 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:68.0) Gecko/20100101 Thunderbird/68.6.0 MIME-Version: 1.0 In-Reply-To: <20200322161418.31606-15-julien@xen.org> Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: 7bit Subject: Re: [Xen-devel] [PATCH 14/17] xen/x86: mm: Re-implement set_gpfn_from_mfn() as a static inline function X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: xen-devel@lists.xenproject.org, Julien Grall , =?UTF-8?Q?Roger_Pau_Monn=c3=a9?= , Wei Liu , Andrew Cooper Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" On 22.03.2020 17:14, julien@xen.org wrote: > From: Julien Grall > > set_gpfn_from_mfn() is currently implement in a 2 part macros.

This series aims to fix the regression, and should unblock several osstest branches. The following report is from osstest with this series applied: http://logs.test-lab.xenproject.org/osstest/logs/149084/ Note the last patch (2/2) is the one that actually fixes the issue. Xen will always use the Ack on exit feature so patche 1/2 don't change the functionality when running a nested Xen, as it always requires SVI to be updated. Thanks, Roger.

Updating RVI however is not tied to the Ack on exit feature, as it signals the next vector to be injected, and hence should always be updated to the next pending vector, regardless of whether Ack on exit is enabled. When not using the Ack on exit feature preserve the previous vector in SVI, so that it's not lost when RVI is updated to contain the pending vector to inject.

This model dates from +an era when it was assumed that the host administrator had control of at +least the privileged software running in the guest (i.e. the guest kernel) +which may still be true in an enterprise deployment but is not generally +true in a cloud environment. The aim of this design is to provide a model +which is purely host driven, requiring no co-operation from the software +running in the guest, and is thus suitable for cloud scenarios. + +PV guests are out of scope for this project because, as is outlined above, +they have a symbiotic relationship with the hypervisor and therefore a +certain level of co-operation is required. + +x86 HVM guests can already be migrated on Xen without guest co-operation +but only if they don’t have PV drivers installed[1] or are not in ACPI +power state S0. The reason for not expecting co-operation if the guest is +any sort of suspended state is obvious, but the reason co-operation is +expected if PV drivers are installed is due to the nature of PV protocols. + +## Xenstore Nodes and Domain ID + +The PV driver model consists of a *frontend* and a *backend*. The frontend +runs inside the guest domain and the backend runs inside a *service domain* +which may or may not be domain 0. The frontend and backend typically pass +data via memory pages which are shared between the two domains, but this +channel of communication is generally established using xenstore (the store +protocol itself being an exception to this for obvious chicken-and-egg +reasons). + +Typical protocol establishment is based on use of two separate xenstore +*areas*. If we consider PV drivers for the *netif* protocol (i.e. class vif) +and assume the guest has domid X, the service domain has domid Y, and the +vif has index Z then the frontend area will reside under the parent node: + +`/local/domain/Y/device/vif/Z` + +All backends, by convention, typically reside under parent node: + +`/local/domain/X/backend` + +and the normal backend area for vif Z would be: + +`/local/domain/X/backend/vif/Y/Z` + +but this should not be assumed. + +The toolstack will place two nodes in the frontend area to explicitly locate +the backend: + + * `backend`: the fully qualified xenstore path of the backend area + * `backend-id`: the domid of the service domain + +and similarly two nodes in the backend area to locate the frontend area: + + * `frontend`: the fully qualified xenstore path of the frontend area + * `frontend-id`: the domid of the guest domain + + +The guest domain only has write permission to the frontend area and +similarly the service domain only has write permission to the backend area, +but both ends have read permission to both areas. + +Under both frontend and backend areas is a node called *state*. This is key +to protocol establishment. Upon PV device creation the toolstack will set +the value of both state nodes to 1 (XenbusStateInitialising[2]). This +should cause enumeration of appropriate devices in both the guest and +service domains. The backend device, once it has written any necessary +protocol specific information into the xenstore backend area (to be read +by the frontend driver) will update the backend state node to 2 +(XenbusStateInitWait). From this point on PV protocols differ slightly; the +following illustration is true of the netif protocol. + +Upon seeing a backend state value of 2, the frontend driver will then read +the protocol specific information, write details of grant references (for +shared pages) and event channel ports (for signalling) that it has created, +and set the state node in the frontend area to 4 (XenbusStateConnected). +Upon see this frontend state, the backend driver will then read the grant +references (mapping the shared pages) and event channel ports (opening its +end of them) and set the state node in the backend area to 4. Protocol +establishment is now complete and the frontend and backend start to pass +data. + +Because the domid of both ends of a PV protocol forms a key part of +negotiating the data plane for that protocol (because it is encoded into +both xenstore nodes and node paths), and because guest’s own domid and the +domid of the service domain are visible to the guest in xenstore (and hence +ay cached internally), and neither are necessarily preserved during +migration, it is hence necessary to have the co-operation of the frontend +in re-negotiating the protocol using the new domid after migration. + +Moreover the backend-id value will be used by the frontend driver in +setting up grant table entries and event channels to communicate with the +service domain, so the co-operation of the guest is required to +re-establish these in the new host environment after migration. + +Thus if we are to change the model and support migration of a guest with PV +drivers, without the co-operation of the frontend driver code, the paths and +values in both the frontend and backend xenstore areas must remain unchanged +and valid in the new host environment, and the grant table entries and event +channels must be preserved (and remain operational once guest execution is +resumed). + +Because the service domain’s domid is used directly by the guest in setting +up grant entries and event channels, the backend drivers in the new host +environment must be provided by service domain with the same domid. Also, +because the guest can sample its own domid from the frontend area and use +it in hypercalls (e.g. HVMOP_set_param) rather than DOMID_SELF, the guest +domid must also be preserved to maintain the ABI. + +Furthermore, it will necessary to modify backend drivers to re-establish +communication with frontend drivers without perturbing the content of the +backend area or requiring any changes to the values of the xenstore state +nodes. + +## Other Para-Virtual State + +### Shared Rings + +Because the console and store protocol shared pages are actually part of +the guest memory image (in an E820 reserved region just below 4G in x86 +VMs) then the content will get migrated as part of the guest memory image. +Hence no additional code is require to prevent any guest visible change in +the content. + +### Shared Info + +There is already a record defined in *libxenctrl Domain Image Format* [3] +called `SHARED_INFO` which simply contains a complete copy of the domain’s +shared info page. It is not currently incuded in an HVM (type `0x0002`) +migration stream. It may be feasible to include it as an optional record +but it is not clear that the content of the shared info page ever needs +to be preserved for an HVM guest. + +For a PV guest the `arch_shared_info` sub-structure contains important +information about the guest’s P2M, but this information is not relevant for +an HVM guest where the P2M is not directly manipulated via the guest. The +other state contained in the `shared_info` structure relates the domain +wall-clock (the state of which should already be transferred by the `RTC` +HVM context information which contained in the `HVM_CONTEXT` save record) +and some event channel state (particularly if using the *2l* protocol). +Event channel state will need to be fully transferred if we are not going +to require the guest co-operation to re-open the channels and so it should +be possible to re-build a shared info page for an HVM guest from such other +state. + +Note that the shared info page also contains an array of +`XEN_LEGACY_MAX_VCPUS` (32 for x86) `vcpu_info` structures. A domain may +nominate a different guest physical address to use for the vcpu info. This +is mandatory if a domain wants to use more than XEN_LEGACY_MAX_VCPUS vCPUs +and optional otherwise. This mapping is not currently transferred in the +migration state so this will either need to be added into an existing save +record, or an additional type of save record will be needed. + +### Xenstore Watches + +As mentioned above, no domain Xenstore state is currently transferred in +the migration stream. There is a record defined in *libxenlight Domain +Image Format* [4] called `EMULATOR_XENSTORE_DATA` for transferring Xenstore +nodes relating to emulators but no record type is defined for nodes +relating to the domain itself, nor for registered *watches*. A XenStore +watch is a mechanism used by PV frontend and backend drivers to request a +notification if the value of a particular node (e.g. the other end’s state +node) changes, so it is important that watches continue to function after a +migration. One or more new save records will therefore be required to +transfer Xenstore state. It will also be necessary to extend the *store* +protocol[5] with mechanisms to allow the toolstack to acquire the list of +watches that the guest has registered and for the toolstack to register a +watch on behalf of a domain. + +### Event channels + +Event channels are essentially the para-virtual equivalent of interrupts. +They are an important part of post PV protocols. Normally a frontend driver +creates an *inter-domain* event channel between its own domain and the +domain running the backend, which it discovers using the `backend-id` node +in Xenstore (see above), by making a `EVTCHNOP_alloc_unbound` hypercall. +This hypercall allocates an event channel object in the hypervisor and +assigns a *local port* number which is then written into the frontend area +in Xenstore. The backend driver then reads this port number and *binds* to +the event channel by specifying it, and the value of `frontend-id`, as +*remote domain* and *remote port* (respectively) to a +`EVTCHNOP_bind_interdomain` hypercall. Once connection is established in +this fashion frontend and backend drivers can use the event channel as a +*mailbox* to notify each other when a shared ring has been updated with new +requests or response structures. + +Currently no event channel state is preserved on migration, requiring +frontend and backend drivers to create and bind a complete new set of event +channels in order to re-establish a protocol connection. Hence, one or more +new save records will be required to transfer event channel state in order +to avoid the need for explicit action by frontend drivers running in the +guest. Note that the local port numbers need to preserved in this state as +they are the only context the guest has to refer to the hypervisor event +channel objects. + +Note also that the PV *store* (Xenstore access) and *console* protocols +also rely on event channels which are set up by the toolstack. Normally, +early in migration, the toolstack running on the remote host would set up a +new pair of event channels for these protocols in the destination domain. +These may not be assigned the same local port numbers as the protocols +running in the source domain. For non-cooperative migration these channels +must either be created with fixed port numbers, or their creation must be +avoided and instead be included in the general event channel state +record(s). + +### Grant table + +The grant table is essentially the para-virtual equivalent of an IOMMU. For +example, the shared rings of a PV protocol are *granted* by a frontend +driver to the backend driver by allocating *grant entries* in the guest’s +table, filling in details of the memory pages and then writing the *grant +references* (the index values of the grant entries) into Xenstore. The +grant references of the protocol buffers themselves are typically written +directly into the request structures passed via a shared ring. + +The guest is responsible for managing its own grant table. No hypercall is +required to grant a memory page to another domain. It is sufficient to find +an unused grant entry and set bits in the entry to give read and/or write +access to a remote domain also specified in the entry along with the page +frame number. Thus the layout and content of the grant table logically +forms part of the guest state. + +Currently no grant table state is migrated, requiring a guest to separately +maintain any state that it wishes to persist elsewhere in its memory image +and then restore it after migration. Thus to avoid the need for such +explicit action by the guest, one or more new save records will be required +to migrate the contents of the grant table. + +# Outline Proposal + +* PV backend drivers will be modified to unilaterally re-establish +connection to a frontend if the backend state node is restored with value 4 +(XenbusStateConnected)[6]. + +* The toolstack choose a randomized domid for initial creation or default +migration, but preserve the source domid non-cooperative migration. +Non-Cooperative migration will have to be denied if the domid is +unavailable on the target host, but randomization of domid on creation +should hopefully minimize the likelihood of this. Non-Cooperative migration +to localhost will clearly not be possible. + +* `xenstored` should be modified to implement the new mechanisms needed. +See *Other Para-Virtual State* above. A further design document will +propose additional protocol messages. + +* Within the migration stream extra save records will be defined as +required. See *Other Para-Virtual State* above. A further design document +will propose modifications to the libxenlight and libxenctrl Domain Image +Formats. + +* An option should be added to the toolstack to initiate a non-cooperative +migration, instead of the (default) potentially co-operative migration. +Essentially this should skip the check to see if PV drivers and migrate as +if there are none present, but also enabling the extra save records. Note +that at least some of the extra records should only form part of a +non-cooperative migration stream. For example, migrating event channel +state would be counter productive in a normal migration as this will +essentially leak event channel objects at the receiving end. Others, such +as grant table state, could potentially harmlessly form part of a normal +migration stream. + +* * * +[1] PV drivers are deemed to be installed if the HVM parameter +*HVM_PARAM_CALLBACK_IRQ* has been set to a non-zero value. + +[2] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/public/io/xenbus.h + +[3] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/specs/libxc-migration-stream.pandoc + +[4] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/specs/libxl-migration-stream.pandoc + +[5] See https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/misc/xenstore.txt + +[6] `xen-blkback` and `xen-netback` have already been modified in Linux to do +this. -- 2.20.1 From xen-devel-bounces@lists.xenproject.org Fri Mar 27 13:50:25 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Fri, 27 Mar 2020 13:50:25 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jHpNR-0006p1-7l;

Are we really > okay with this? Well, the truncation was already silently happening as we call get_page_from_gfn() in map_guest_page(). So it is not worse than the current situation. Although, there are a slight advantage with the new code as you can more easily spot potential truncation. Indeed, you could add some type check in _gfn().

Of course there are, as soon as the guest uses the event channels. Did you see Jürgen's patch sent earlier this week, aiming to address the same issue of larger vCPU counts being a problem ("tools/libxl: make default of max event channels dependant on vcpus")? See the discussion there.

Event channels are allocated using buckets. Everytime you will a bucket, a new bucket will be allocated. By increasing the limit, you effectively increase the number of buckets than can be allocated. So while I agree that the default allocation will be the same, you effectively allow the guest to use more resource in Xen. Therefore I don't think this is acceptable to lift the limits for all the guests.

This patch adds the new public header and the low level implementation, entered via the domain_save() or domain_load() functions. Subsequent patches will introduce other parts of the framwork, and code that will make use of it within the current version of the libxc migration stream.

Therefore the whole logic to allocate a fake page for some IO APICs is unnecessary. With the logic removed, the code can be simplified a lot as we don't need to go through all the IO APIC if SMP has not been detected or a bogus zero IO-APIC address has been detected. To avoid another level of tabulation, the simplification is now moved in its own function.

The issue is sched_set_affinity will call the adjust_affinity method of the cpupool. If defined, the new cpupool may use unit->priv (e.g. credit), which at this point still references the old cpupool private UNIT data structure. This change fixes the bug by moving the switch of unit->priv earler in the function. Signed-off-by: Jeff Kubascik --- Hello, I've been working on updating the arinc653 scheduler to support multicore for a few months now. In the process of testing, I came across this obscure bug in the core scheduler code that took me a few weeks to track down. This bug resulted in the credit scheduler writing past the end of the arinc653 private UNIT data structure into the TLSF allocator bhdr structure of the adjacent region. This required some deep diving into the TLSF allocator code to trace the bug back to this point.

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

There are use of GFN helpers in the series, but I wanted to avoid introducing them in the middle of something else. I can try to find a couple of occurences I can switch to use them now. Regarding the term GFN, it is not meant to be HVM only. So we may want to prefix the helpers with hvm_ to make it clear. > > A possible route to go may be to e.g. accompany > {xen,compat}_pfn_to_cr3() with {xen,compat}_mfn_to_cr3(), and > leave the GFN aspect out until such patch that would actually > use them (which may then make clear that these actually want > to live in a header specifically applicable to translated > guests). I am thinking to introduce 3 sets of helpers: - hvm_cr3_to_gfn()/hvm_gfn_to_cr3(): Handle the CR3 for HVM guest - {xen, compat}_mfn_to_cr3()/{xen, compat}_cr3_to_mfn(): Handle the CR3 for PV guest. - host_cr3_to_mfn()/host_mfn_to_cr3(): To handle the host cr3. What do you think?

If you want to get rid of the cast here you need to change the type of the table parameter to l1_pgentry_t * instead of void *. Thanks, Roger.

It is doing *exactly* the same things. The whole point of typesafe is to use typesafe helper not open-coding test everywhere. It is also easier to spot any use of MFN 0 within the code as you know could grep "_mfn(0)".

The former is a xen_pfn_t, whilst the latter is mfn_t. In practice they are both unsigned long on x86, so it should be fine to use PRI_mfn.

While there, would you mind changing u64 to uint64_t? (here and
above)

I'll do that in the next ver= sion.

I don't think removing this cast is correct, as you would be doing a plain addition to a pointer instead of fetching the next entry in the
array of l1_pgentry_t entries.

If you want to get rid of the cast here you need to change the type of
the table parameter to l1_pgentry_t * instead of void *.

Yes, you are correct. Since void* is a point= er to an unknown type we can't do pointer arithmetic on it, as the comp= iler wouldn't know how big the thing pointed to is. Thus, it is necessa= ry to keep the cast on the "table".

Ah! = I am sorry for this mistake. But, I am afraid why I didn't get warning = during compilation.
I'll remove these changes in the next ver= sion.

To add some context to this comment: new code has been using uintX
variants. We want to migrate existing code gradually. Since you're
touching these lines anyway, it is a good chance to do the migration.

When you do this in your next version, please add a line in the commit
message saying something along the line that "Take the chance to chang= e
some u64 to uint64_t".

Thanks for = the suggestion. I'll do the changes in the next version.

This case was clearly observed at one point in the past, given the subsequent overrun detection, but without comprehending that the damage was already done. Make the logic consistent with container_fast_forward() and pass size_left in to install_equiv_cpu_table().

Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

No cast is needed. Also, changed some u64/u32 to uint64_t/uint32_t.

Macro min return the minimum of the > two compared values. While I understand the ternary operator is doing exactly the same as a min(), I read the current code as "If there is an error then return the error code, otherwise return 0". This is quite different from the meaning of "min" which is "I want the minimum of the two values". Therefore I am not convinced using min() is the right thing to do. > Signed-off-by: Simran Singhal > --- > xen/arch/x86/bzimage.c | 2 +- > xen/arch/x86/mm.c | 2 +- > xen/arch/x86/mm/p2m-ept.c | 2 +- > 3 files changed, 3 insertions(+), 3 deletions(-) > > diff --git a/xen/arch/x86/bzimage.c b/xen/arch/x86/bzimage.c > index ac4fd428be..f396aa3445 100644 > --- a/xen/arch/x86/bzimage.c > +++ b/xen/arch/x86/bzimage.c > @@ -136,7 +136,7 @@ int __init bzimage_parse(void *image_base, void **image_start, > *image_len = output_len;

Although the calculation in the end is the same (void* considered of size 1), I would still keep the cast such that the semantics is correct. Wei.

I bet the ovf = 1 line is the reason why you didn't remove ovf out right. I think you can perhaps just remove ovf here. It would make any difference logically. Other changes look correct to me. Wei.

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

I didn't think so, and hence I've used "pending". Whether the result of the first two is indeed correct is only known after the 3rd.

This should be limited in order to avoid any unwanted view switch. The new xc_altp2m_set_visibility() solves this by making views invisible to vmfunc. This is done by having a separate arch.altp2m_working_eptp that is populated and made invalid in the same places as altp2m_eptp. This is written to EPTP_LIST_ADDR. The views are made in/visible by marking them with INVALID_MFN or copying them back from altp2m_eptp. To have consistency the visibility also applies to p2m_switch_domain_altp2m_by_id(). The usage of this hypercall is aimed at dom0 having a logic with a number of views created and at some time there is a need to be sure that only some of the views can be switched, saving the rest and making them visible when the time is right. Note: If altp2m mode is set to mixed the guest is able to change the view visibility and then call vmfunc.

Maybe some variation thereof: - hvm_cr3_to_gfn()/hvm_gfn_to_cr3(): Handle the CR3 for HVM guest - {pv,compat}_mfn_to_cr3()/{pv,compat}_cr3_to_mfn(): Handle the CR3 for PV guest - cr3_to_mfn()/mfn_to_cr3(): To handle the host cr3 ? This is because I'd prefer to avoid host_ prefixes (albeit I'm not entirely opposed to such), and I'd also prefer to use xen_ prefixes as they're generally ambiguous as to what aspect of "Xen" they actually mean.

What I insit on is that readability of the result of such changes be also kept in mind. The mfn_eq() construct is (I think) clearly less easy to read and recognize than the simpler alternative suggested.

If this was used outside of the accessor definitions, I'd probably agree. But the accessor definitions exist specifically to abstract away such things from use sites. Hence, bike- shedding or not, if Andrew was clearly agreeing with your view, I'd accept it. If he's indifferent, I'd prefer the #define to be dropped.

I'm not talking about "everything". As soon as you use mfn_x() _anywhere_, type-safety is gone. Since in printk() and alike you unavoidably have to use it (at least for now), there's no win from using e.g. mfn_add() as you do here, imo. And hence the readability aspect gets even higher significance. >> I would also prefer if you left %#lx alone, with the 2nd best >> option being to also use PRI_gfn alongside PRI_mfn.

Hmm, xen/mm.h suggests a partial connection between e.g. mfn_t and PRI_mfn, yes, but I think this is unhelpful as long as mfn_x() needs to be explicitly used when specifying the printk() arguments. Instead I view PRI_mfn and alike as a more general format usable also for MFNs stored in unsigned long rather than mfn_t. I agree though that views here may differ.

I usually cast things to void * instead of char * or uint8_t * in order to do pointer additions with size 1. Thanks, Roger.

If the new functionality isn't a good fit for either, perhaps its name would better reflect its connection to save/restore records? xen-sr-dump looks pretty clumsy to me, but still seems better than a name easily mixed up with others.

Thanks for doing the switch of content to type uint64_t. You should
however not change the type of res to uint64_t also IMO, as you are
not touching that line anyway.

Thanks f= or your feedback Roger and Wei.
My bad, I thought I need to chang= e all the unintX to uintX_t in the function
set_vvmcs_virtual().<= /div>

Sorry for the inconvenience.
=C2=A0<= /div>

With that fixed:

Hmm... ovf can potentially be set in the for loop before this hunk, but
then immediately get overwritten by the function call. I bet the ovf =3D 1<= br> line is the reason why you didn't remove ovf out right.

I think you can perhaps just remove ovf here. It would make any
difference logically.

Other changes look correct to me.

Thank= s for your feedback.
Ah! I agree on "ovf =3D 1" is = the reason I decided to leave ovf as it is.
I'll remove ovf n= ow and send the new version of this patch.

Afaict it's covering for UCODE_MAGIC. There's no good sizeof() that could be used instead, so how about getting rid of this addend altogether by setting offset to sizeof(uint32_t) near if ( *(const uint32_t *)buf != UCODE_MAGIC ) in cpu_request_microcode() and adding sizeof(header[0]) into *offset near if ( header[0] == UCODE_MAGIC && header[1] == UCODE_EQUIV_CPU_TABLE_TYPE ) in container_fast_forward()? (The code following the big, 7- bullet-point comment in cpu_request_microcode() may also need adjustment, but I wonder if we couldn't better get rid of it altogether.) However, since the change as is looks correct to me and doesn't make the situation much worse, I'm not objecting to you also putting it in as is, in which case Reviewed-by: Jan Beulich Jan From xen-devel-bounces@lists.xenproject.org Mon Mar 30 12:02:12 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Mon, 30 Mar 2020 12:02:12 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jIt7E-0000sr-PQ;

I am in the process of rewriting all of this.  I'm not entirely convinced of the correctness of cpu_request_microcode() in the first place, but I also can't find a concrete problem with it. > (The code following the big, 7- > bullet-point comment in cpu_request_microcode() may also > need adjustment, but I wonder if we couldn't better get rid > of it altogether.)

However, given the rate of finding issues, I'm going to hold off on committing this until I've completed the rewrite, and am fairly sure there are no further issues lurking. ~Andrew From xen-devel-bounces@lists.xenproject.org Mon Mar 30 12:08:51 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Mon, 30 Mar 2020 12:08:51 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jItDY-00014w-HO;

R. Silva from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

JIRA issue: https://xenproject.atlassian.net/browse/XEN-89 The fork operation is implemented as part of the "xl fork-vm" command: xl fork-vm -C -Q -m By default a fully functional fork is created. The user is in charge however to create the appropriate config file for the fork and to generate the QEMU save file before the fork-vm call is made. The config file needs to give the fork a new name at minimum but other settings may also require changes. Certain settings in the config file of both the parent and the fork have to be set to default. Details are documented. The interface also allows to split the forking into two steps: xl fork-vm --launch-dm no \ -m \ -p xl fork-vm --launch-dm late \ -C \ -Q \ The split creation model is useful when the VM needs to be created as fast as possible. The forked VM can be unpaused without the device model being launched to be monitored and accessed via VMI. Note however that without its device model running (depending on what is executing in the VM) it is bound to misbehave or even crash when its trying to access devices that would be emulated by QEMU. We anticipate that for certain use-cases this would be an acceptable situation, in case for example when fuzzing is performed of code segments that don't access such devices. Launching the device model requires the QEMU Xen savefile to be generated manually from the parent VM. This can be accomplished simply by connecting to its QMP socket and issuing the "xen-save-devices-state" command. For example using the standard tool socat these commands can be used to generate the file: socat - UNIX-CONNECT:/var/run/xen/qmp-libxl- { "execute": "qmp_capabilities" } { "execute": "xen-save-devices-state", \ "arguments": { "filename": "/path/to/save/qemu_state", \ "live": false} } At runtime the forked VM starts running with an empty p2m which gets lazily populated when the VM generates EPT faults, similar to how altp2m views are populated. If the memory access is a read-only access, the p2m entry is populated with a memory shared entry with its parent. For write memory accesses or in case memory sharing wasn't possible (for example in case a reference is held by a third party), a new page is allocated and the page contents are copied over from the parent VM. Forks can be further forked if needed, thus allowing for further memory savings. A VM fork reset hypercall is also added that allows the fork to be reset to the state it was just after a fork, also accessible via xl: xl fork-vm --fork-reset -p This is an optimization for cases where the forks are very short-lived and run without a device model, so resetting saves some time compared to creating a brand new fork provided the fork has not aquired a lot of memory. If the fork has a lot of memory deduplicated it is likely going to be faster to create a new fork from scratch and asynchronously destroying the old one. The series has been tested with Windows VMs and functions as expected. Linux VMs when forked from a running VM will have a frozen VNC screen. Linux VMs at this time can only be forked with a working device model when the parent VM was restored from a snapshot using "xl restore -p". This is a known limitation. Also note that PVHVM/PVH Linux guests have not been tested. Forking most likely works but PV devices and drivers would require additional wiring to set things up properly since the guests are unaware of the forking taking place, unlike the save/restore routine where the guest is made aware of the procedure. Forking time has been measured to be 0.0007s, device model launch to be around 1s depending largely on the number of devices being emulated. Fork resets have been measured to be 0.0001s under the optimal circumstances.

This allows the forked VM to reset into the same state the parent VM is in a faster way then creating a new fork would be. Measurements show about a 2x speedup during normal fuzzing operations. Performance may vary depending how much memory got allocated for the forked VM. If it has been completely deduplicated from the parent VM then creating a new fork would likely be more performant.

Mind sharing them? No, I don't have any numbers. Would you prefer a different wording or a better explanation? I also realized there is a typo in there (or/of).

However the C code were still using String_Val() to access them. While the underlying structure is the same between string and bytes, a string is meant to be immutable. OCaml 4.06.1 and later will enforce it. Therefore, it will not be possible to build the OCaml libs when using -safe-string. This is because String_val() will return a const value. To avoid plain cast in the code, the code is now switched to use Bytes_val(). As the macro is not defined in older OCaml version, we need to provide a stub.

Since Ocaml 4.06.01, String_val() will return a const char * when using -safe-string. This will result to a build failure because xc_send_debug_keys() expects a char *. The function should never modify the parameter 'keys' and therefore the parameter should be const. Unfortunately, this is not directly possible because DECLARE_HYPERCALL_BOUNCE() is expecting a non-const variable. A new macro DECLARE_HYPERCALL_BOUNCE_IN() is introduced and will take care of const parameter. The first user will be xc_send_debug_keys() but this can be used in more place in the future.

On OCaml newer than 4.06.1, String_Val() will return a const char * when using -safe-string leading to build failure when this is used in place where char * is expected. The main use in Xen code base is when a new string is allocated. The suggested approach by the OCaml community [1] is to use the helper caml_alloc_initialized_string() but it was introduced by OCaml 4.06.1. The next best approach is to cast String_val() to (char *) as the helper would have done. So use it when we need to update the new string using memcpy().

Let me start with I think correctness is more important than speed. So I would have expected your commit message to contain some fact why synchronization is going to be slow and why this is a problem. To give you a concrete example, the implementation of set/way instructions are really slow (it could take a few seconds depending on the setup). However, this was fine because not implementing them correctly would have a greater impact on the guest (corruption) and they are not used often. I don't think the performance in our case will be in same order magnitude. It is most likely to be in the range of milliseconds (if not less) which I think is acceptable for emulation (particularly for the vGIC) and the current uses. So lets take a step back and look how we could implement ISACTIVER/ICACTIVER correctly. The only thing we need is a snapshot of the interrupts state a given point. I originally thought it would be necessary to use domain_pause() which is quite heavy, but I think we only need the vCPU to enter in Xen and sync the states of the LRs. Roughly the code would look like (This is not optimized): for_each_vcpu(d, v) { if ( v->is_running ) smp_call_function(do_nothing(), v->cpu); } /* Read the state */ A few remarks: * The function do_nothing() is basically a NOP. * I am suggesting to use smp_call_function() rather smp_send_event_check_cpu() is because we need to know when the vCPU has synchronized the LRs. As the function do_nothing() will be call afterwards, then we know the the snapshot of the LRs has been done * It would be possible to everything in one vCPU. * We can possibly optimize it for the SGIs/PPIs case This is still not perfect, but I don't think the performance would be that bad.

So I think your implementation is going to introduce a deadlock in the guest. Let's imagine a guest with 2 vCPUs (A and B) with the following setup: * The HW SPI 32 is routed to and serviced by vCPU B. * vCPU A will routinely wait for any pending SPI 32 to be finished before performing a specific task. In the current form of the vGIC, vCPU B will not exit to Xen when SPI 32 has been deactivated. Instead, the vCPU will continue to run until an unrelated trap happen (I/O emulation, IRQs...). Depending on your setup (think NULL scheduler) this may happen in a really long time (or never). Until the vCPU B exit to Xen, SPI 32 may be considered as active. Therefore vCPU A will keep waiting and be block until vCPU B is finally trapping in Xen. My example above is basically a cut down version of __synchronize_hardirq() in Linux. In practice, you may be lucky most of the times because there will be trap happening time to time. However, it also means the task you need to perform on vCPU A will be delayed. So I would not really bet on the trap here. You have two options: 1) Force the vCPU to trap when deactivating an interrupt 2) For the vCPUs to exiting when reading I{S,C}ACTIVER 1) will incur cost on every interrupts which is not great. So I think your best option is 2) here.

I'm sure we use this in a few places, to copy to e.g. a handle derived from "void". Compatibility of types (disallowing other than void) is checked by the comparison on the line immediately after the line you change. Yes "_d+(off)" right above here then changes its result. I consider it pretty likely you'd notice this issue once you go beyond just build testing. To address this, I guess we need to find an expression along the lines of that comparison, which does not cause any code to be generated, but which verifies the properties we care about. The line you change should be left alone, from all I can tell right now.

No, it should be left as is - it's about _binary_ compatibility (e.g. if structure layout changes, or a sub-function gets dropped).

If the BIOS left us with asymmetric microcode, rejecting updates in cpu_request_microcode() would prevent us levelling the system even if only up to the final level. Also, failing to cache microcode misses an opportunity to get beyond the final level via the S3 path. Move check_final_patch_levels() earlier and use it in apply_microcode(). Reword the error message to be more informative, and use -ENXIO as this corner case has nothing to do with permissions.

This case was clearly observed at one point in the past, given the subsequent overrun detection, but without comprehending that the damage was already done. Make the logic consistent with container_fast_forward() and pass size_left in to install_equiv_cpu_table().

This is not safe to heterogeneous scenarios, and as Xen doesn't support such situations to being with, can be used to simplify things further. The CPUID.1.EAX => processor_rev_id mapping is fixed for an individual part. We can cache the single appropriate entry on first discovery, and forgo duplicating the entire table. Alter install_equiv_cpu_table() to be scan_equiv_cpu_table() which is responsible for checking the equivalency table and caching appropriate details. It now has a check for finding a different mapping (which indicates that one of the tables we've seen is definitely wrong). A return value of -ESRCH is now used to signify "everything fine, but nothing applicable for the current CPU", which is used to select the container_fast_forward() path. Drop the printk(), as each applicable error path in scan_equiv_cpu_table() already prints diagnostics.

An alternative would be to embed the full equivelancy table, but it is fairly large, and would need adjusting every time a new model/stepping was released. --- xen/arch/x86/cpu/microcode/amd.c | 112 ++++++++++++++++++++++----------------- 1 file changed, 64 insertions(+), 48 deletions(-) diff --git a/xen/arch/x86/cpu/microcode/amd.c b/xen/arch/x86/cpu/microcode/amd.c index d2ecc7ae87..d3439b0c6c 100644 --- a/xen/arch/x86/cpu/microcode/amd.c +++ b/xen/arch/x86/cpu/microcode/amd.c @@ -61,8 +61,6 @@ struct __packed microcode_header_amd { struct microcode_patch { struct microcode_header_amd *mpb; size_t mpb_size; - struct equiv_cpu_entry *equiv_cpu_table; - size_t equiv_cpu_table_size; }; /* Temporary, until the microcode_* structure are disentangled. */ @@ -74,6 +72,31 @@ struct mpbhdr { uint8_t data[]; }; +/* + * Microcode updates for different CPUs are distinguished by their + * processor_rev_id in the header.

However, the patch size check depends only on the CPU family. Move the check earlier to when we are parsing the container, which avoids caching bad microcode in the first place, and allows us to avoid storing the size at all.

Make this change (taking time to rename 'mc_amd' to its eventual 'patch' to reduce the churn in the series), and a later cleanup will make it uniformly take a struct microcode_patch.

Delete get_ucode_from_buffer_amd() and rewrite the loop in cpu_request_microcode() to have 'saved' point into 'buf' until we finally decide to duplicate that blob and return it to our caller. Introduce a new struct container_microcode to simplify interpreting the container format. Doubly indent the logic to substantially reduce the churn in a later change.

Rewrite it so all container structure handling is in this one function. Rewrite struct mpbhdr as struct container_equiv_table to aid parsing. Drop container_fast_forward() entirely, and shrink scan_equiv_cpu_table() to just its searching/caching logic. container_fast_forward() gets logically folded into the microcode blob scanning loop, except that a skip path is inserted, which is conditional on whether scan_equiv_cpu_table() thinks there is appropriate microcode to find. With this change, we now scan to the end of all provided microcode containers, and no longer give up at the first applicable one.

Whenever if_changed is called, the target must have FORCE as dependency so that if_changed can check if the command line to be run has changed, so the macro $(real-prereqs) must be used to discover the dependencies without "FORCE". Whenever a target isn't in obj-y, it should be added to extra-y so the .*.cmd dependency file associated with the target can be loaded. This is done for xsm/flask/ and both common/lib{elf,fdt}/ and arch/x86/Makefile. For the targets that generate .*.d dependency files, there's going to be two dependency files (.*.d and .*.cmd) until we can merge them together in a later patch via fixdep from Linux. One cleanup, libelf-relocate.o doesn't exist anymore. We import cmd_ld and cmd_objcopy from Linux v5.4.

The build system will automatically + invoke make recursively in subdirectories, provided you let it know of + them. + + To do so, obj-y is used. + acpi lives in a separate directory, and the Makefile present in + drivers/ tells the build system to descend down using the following + assignment. + + Example:: + + #drivers/Makefile + obj-$(CONFIG_ACPI) += acpi/ + + If CONFIG_ACPI is set to 'y' + the corresponding obj- variable will be set, and the build system + will descend down in the apci directory. + The build system only uses this information to decide that it needs + to visit the directory, it is the Makefile in the subdirectory that + specifies what is modular and what is built-in. + + It is good practice to use a `CONFIG_` variable when assigning directory + names. This allows the build system to totally skip the directory if the + corresponding `CONFIG_` option is 'y'. + +Compilation flags +----------------- + + CFLAGS-y and AFLAGS-y + These two flags apply only to the makefile in which they + are assigned. They are used for all the normal cc, as and ld + invocations happening during a recursive build. + + $(CFLAGS-y) is necessary because the top Makefile owns the + variable $(XEN_CFLAGS) and uses it for compilation flags for the + entire tree. And the variable $(CFLAGS) is modified by Config.mk + which evaluated in every subdirs. + + CFLAGS-y specifies options for compiling with $(CC). + AFLAGS-y specifies assembler options. diff --git a/xen/Rules.mk b/xen/Rules.mk index 0def40a00a09..7f28c3bc6c13 100644 --- a/xen/Rules.mk +++ b/xen/Rules.mk @@ -1,3 +1,7 @@ +# +# See docs/misc/xen-makefiles/makefiles.rst on variables that can be used in +# Makefile and are consumed by Rules.mk +# -include $(BASEDIR)/include/config/auto.conf -- Anthony PERARD From xen-devel-bounces@lists.xenproject.org Tue Mar 31 10:31:18 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Tue, 31 Mar 2020 10:31:18 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jJEAq-0000vP-7T; Tue, 31 Mar 2020 10:31:12 +0000 Received: from all-amaz-eas1.inumbo.com ([34.197.232.57] helo=us1-amaz-eas2.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jJEAo-0000v9-PE for xen-devel@lists.xenproject.org; Tue, 31 Mar 2020 10:31:10 +0000 X-Inumbo-ID: bb7a65d5-733a-11ea-ba0c-12813bfff9fa Received: from esa1.hc3370-68.iphmx.com (unknown [216.71.145.142]) by us1-amaz-eas2.inumbo.com (Halon) with ESMTPS id bb7a65d5-733a-11ea-ba0c-12813bfff9fa; Tue, 31 Mar 2020 10:31:08 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=citrix.com; s=securemail; t=1585650669; h=from:to:cc:subject:date:message-id:in-reply-to: references:mime-version:content-transfer-encoding; bh=bHmbNn+xSjp5FPcLqfUyNkXyOAlVeYUAo2LAo99Colo=; b=Mwj+3OaEOY2ZBW/o2daYxFPGSM5dqLBB12qgqBGunILpTEKWMHGMqSke HtLR2xAmnkzrJOOadz1cN5M5ZF5alMRAPwHUMG5sYrgLbX0F9a62hskU5 FP/WbFXfKl4c7S6yjoyJGI1mMfpXThdoNFycUqD3zyg3YsVOeeaqYIiAP o=; Authentication-Results: esa1.hc3370-68.iphmx.com; dkim=none (message not signed) header.i=none; spf=None smtp.pra=anthony.perard@citrix.com; spf=Pass smtp.mailfrom=anthony.perard@citrix.com; spf=None smtp.helo=postmaster@mail.citrix.com Received-SPF: None (esa1.hc3370-68.iphmx.com: no sender authenticity information available from domain of anthony.perard@citrix.com) identity=pra; client-ip=162.221.158.21; receiver=esa1.hc3370-68.iphmx.com; envelope-from="anthony.perard@citrix.com"; x-sender="anthony.perard@citrix.com"; x-conformance=sidf_compatible Received-SPF: Pass (esa1.hc3370-68.iphmx.com: domain of anthony.perard@citrix.com designates 162.221.158.21 as permitted sender) identity=mailfrom; client-ip=162.221.158.21; receiver=esa1.hc3370-68.iphmx.com; envelope-from="anthony.perard@citrix.com"; x-sender="anthony.perard@citrix.com"; x-conformance=sidf_compatible; x-record-type="v=spf1"; x-record-text="v=spf1 ip4:209.167.231.154 ip4:178.63.86.133 ip4:195.66.111.40/30 ip4:85.115.9.32/28 ip4:199.102.83.4 ip4:192.28.146.160 ip4:192.28.146.107 ip4:216.52.6.88 ip4:216.52.6.188 ip4:162.221.158.21 ip4:162.221.156.83 ip4:168.245.78.127 ~all" Received-SPF: None (esa1.hc3370-68.iphmx.com: no sender authenticity information available from domain of postmaster@mail.citrix.com) identity=helo; client-ip=162.221.158.21; receiver=esa1.hc3370-68.iphmx.com; envelope-from="anthony.perard@citrix.com"; x-sender="postmaster@mail.citrix.com"; x-conformance=sidf_compatible IronPort-SDR: DvYawsXKEXC6awT2cHsXcWfV6x//viIjD3hTAbpaqyBW4QbZWaiEAlqovsqjePmT6uGJqnJC7i uTZ8qUbmmrogWoBBAwwixf+VLqCmFo4tZhGnWrJTAX5XT2TpC6f+05e5PMBEyD704VshiPJPuq JOSbeaZ7R/dtpu9DVJANZRZrIs0hWBN4DpX6fDs9//hlLLmciZwSoGRdX5oBUGnqRm/iIS8XlJ vmGOlEWfSW7Qyu+LQ3dXANoJfy0KsgGG68Ga3PQVxsSsEtl3LJ/KLqAKcM2o+Q48H0A9vQ8da1 PQ4= X-SBRS: 2.7 X-MesageID: 15138784 X-Ironport-Server: esa1.hc3370-68.iphmx.com X-Remote-IP: 162.221.158.21 X-Policy: $RELAYED X-IronPort-AV: E=Sophos;i="5.72,327,1580792400"; d="scan'208";a="15138784" From: Anthony PERARD To: Subject: [XEN PATCH v4 04/18] xen/build: include include/config/auto.conf in main Makefile Date: Tue, 31 Mar 2020 11:30:48 +0100 Message-ID: <20200331103102.1105674-5-anthony.perard@citrix.com> X-Mailer: git-send-email 2.25.1 In-Reply-To: <20200331103102.1105674-1-anthony.perard@citrix.com> References: <20200331103102.1105674-1-anthony.perard@citrix.com> MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Content-Type: text/plain X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Stefano Stabellini , Julien Grall , Wei Liu , Andrew Cooper , Ian Jackson , George Dunlap , Jan Beulich , Anthony PERARD Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" We are going to generate the CFLAGS early from "xen/Makefile" instead of in "Rules.mk", but we need to include "config/auto.conf", so include it in "Makefile". Before including "config/auto.conf" we check which make target a user is calling, as some targets don't need "auto.conf". For targets that needs auto.conf, make will generate it (and a default .config if missing). root-make-done is to avoid doing the calculation again once Rules.mk takes over and is been executed with the root Makefile. When Rules.mk is including xen/Makefile, `config-build' and `need-config' are undefined so auto.conf will not be included again (it is already included by Rules.mk) and kconfig target are out of reach of Rules.mk. We are introducing a target %config to catch all targets for kconfig. So we need an extra target %/.config to prevent make from trying to regenerate $(XEN_ROOT)/.config that is included in Config.mk. The way targets are filtered is inspired by Kbuild, with some code imported from Linux. That's why there is PHONY variable that isn't used yet, for example. Signed-off-by: Anthony PERARD --- Notes: v4: - check that root-make-done hasn't been set to an expected value instead of checking if it has been set at all. - Add a shorthand $(kconfig) to run kconfig targets. v3: - filter only for %config instead of both config %config - keep the multi-target pattern rule trick for include/config/auto.conf instead of using Linux's newer pattern (we dont have tristate.conf so don't need to change it) - use y/n for root-make-done, config-build, need-config instead of relying on ifdef and ifndef and on assigning an empty value meaning undef - use space for indentation - explain why %/.config is suddenly needed. xen/Makefile | 98 +++++++++++++++++++++++++++++--------- xen/scripts/Kbuild.include | 5 ++ 2 files changed, 80 insertions(+), 23 deletions(-) diff --git a/xen/Makefile b/xen/Makefile index e5f7b1ae13bc..8375070e0d41 100644 --- a/xen/Makefile +++ b/xen/Makefile @@ -49,7 +49,73 @@ default: build .PHONY: dist dist: install -build install:: include/config/auto.conf + +ifneq ($(root-make-done),y) +# section to run before calling Rules.mk, but only once. +# +# To make sure we do not include .config for any of the *config targets +# catch them early, and hand them over to tools/kconfig/Makefile + +clean-targets := %clean +no-dot-config-targets := $(clean-targets) \ + uninstall debug cloc \ + cscope TAGS tags MAP gtags \ + xenversion + +config-build := n +need-config := y + +ifneq ($(filter $(no-dot-config-targets), $(MAKECMDGOALS)),) + ifeq ($(filter-out $(no-dot-config-targets), $(MAKECMDGOALS)),) + need-config := n + endif +endif + +ifneq ($(filter %config,$(MAKECMDGOALS)),) + config-build := y +endif + +export root-make-done := y +endif # root-make-done + +include scripts/Kbuild.include + +ifeq ($(config-build),y) +# =========================================================================== +# *config targets only - make sure prerequisites are updated, and descend +# in tools/kconfig to make the *config target + +config: FORCE + $(MAKE) $(kconfig) $@ + +# Config.mk tries to include .config file, don't try to remake it +%/.config: ; + +%config: FORCE + $(MAKE) $(kconfig) $@ + +else # !config-build + +ifeq ($(need-config),y) +include include/config/auto.conf +# Read in dependencies to all Kconfig* files, make sure to run syncconfig if +# changes are detected. +include include/config/auto.conf.cmd + +# Allow people to just run `make` as before and not force them to configure +$(KCONFIG_CONFIG): + $(MAKE) $(kconfig) defconfig + +# The actual configuration files used during the build are stored in +# include/generated/ and include/config/.

That changes the flavor of the CFLAGS and flags intended for one target (like -D__OBJECT_FILE__ and -M%) gets propagated and duplicated. So we start by moving such flags out of $(CFLAGS) and into $(c_flags) which is to be modified by only Rules.mk. __OBJECT_FILE__ is only used by arch/x86/mm/*.c files, so having it in $(c_flags) is enough, we don't need it in $(a_flags). For include/Makefile and as-insn we can keep using CFLAGS, but since it doesn't have -M* flags anymore there is no need to filter them out. The XEN_BUILD_EFI tests in arch/x86/Makefile was filtering out CFLAGS-y, but according to dd40177c1bc8 ("x86-64/EFI: add CFLAGS to check compile"), it was done to filter out -MF. CFLAGS doesn't have those flags anymore, so no filtering is needed. This is inspired by the way Kbuild generates CFLAGS for each targets. Signed-off-by: Anthony PERARD Reviewed-by: Roger Pau Monné --- Notes: v4: - drop change in as-insn macro, and keep filtering-out -M% %.d v3: - include/Makefile: Keep using CFLAGS, but since it doesn't have -M* flags anymore, no need to filter it. - Write c_flags and a_flags on a single line. - arch/x86/Makefile: remove the filter-out of dependency flags they are remove from CFLAGS anyway. (was intended to be done in xen/build: have the root Makefile generates the CFLAGS originally, move the change to this patch). - also modify as-insn as it is now xen/ only. xen/Rules.mk | 23 +++++++++++------------ xen/arch/arm/Makefile | 4 ++-- xen/arch/x86/Makefile | 6 +++--- xen/arch/x86/mm/Makefile | 6 +++--- xen/arch/x86/mm/hap/Makefile | 6 +++--- xen/arch/x86/mm/shadow/Makefile | 6 +++--- xen/include/Makefile | 2 +- 7 files changed, 26 insertions(+), 27 deletions(-) diff --git a/xen/Rules.mk b/xen/Rules.mk index 9079df7978a7..3408a35dbf53 100644 --- a/xen/Rules.mk +++ b/xen/Rules.mk @@ -57,7 +57,6 @@ CFLAGS += -Werror -Wredundant-decls -Wno-pointer-arith $(call cc-option-add,CFLAGS,CC,-Wvla) CFLAGS += -pipe -D__XEN__ -include $(BASEDIR)/include/xen/config.h CFLAGS-$(CONFIG_DEBUG_INFO) += -g -CFLAGS += '-D__OBJECT_FILE__="$@"' ifneq ($(CONFIG_CC_IS_CLANG),y) # Clang doesn't understand this command line argument, and doesn't appear to @@ -70,9 +69,6 @@ AFLAGS += -D__ASSEMBLY__ ALL_OBJS := $(ALL_OBJS-y) -# Get gcc to generate the dependencies for us. -CFLAGS-y += -MMD -MP -MF $(@D)/.$(@F).d - CFLAGS += $(CFLAGS-y) # allow extra CFLAGS externally via EXTRA_CFLAGS_XEN_CORE CFLAGS += $(EXTRA_CFLAGS_XEN_CORE) @@ -146,9 +142,12 @@ endif # Always build obj-bin files as binary even if they come from C source. $(obj-bin-y): CFLAGS := $(filter-out -flto,$(CFLAGS)) +c_flags = -MMD -MP -MF $(@D)/.$(@F).d $(CFLAGS) '-D__OBJECT_FILE__="$@"' +a_flags = -MMD -MP -MF $(@D)/.$(@F).d $(AFLAGS) + built_in.o: $(obj-y) $(extra-y) ifeq ($(obj-y),) - $(CC) $(CFLAGS) -c -x c /dev/null -o $@ + $(CC) $(c_flags) -c -x c /dev/null -o $@ else ifeq ($(CONFIG_LTO),y) $(LD_LTO) -r -o $@ $(filter-out $(extra-y),$^) @@ -159,7 +158,7 @@ endif built_in_bin.o: $(obj-bin-y) $(extra-y) ifeq ($(obj-bin-y),) - $(CC) $(AFLAGS) -c -x assembler /dev/null -o $@ + $(CC) $(a_flags) -c -x assembler /dev/null -o $@ else $(LD) $(LDFLAGS) -r -o $@ $(filter-out $(extra-y),$^) endif @@ -178,7 +177,7 @@ SRCPATH := $(patsubst $(BASEDIR)/%,%,$(CURDIR)) %.o: %.c Makefile ifeq ($(CONFIG_ENFORCE_UNIQUE_SYMBOLS),y) - $(CC) $(CFLAGS) -c $< -o $(@D)/.$(@F).tmp -MQ $@ + $(CC) $(c_flags) -c $< -o $(@D)/.$(@F).tmp -MQ $@ ifeq ($(CONFIG_CC_IS_CLANG),y) $(OBJCOPY) --redefine-sym $<=$(SRCPATH)/$< $(@D)/.$(@F).tmp $@ else @@ -186,11 +185,11 @@ else endif rm -f $(@D)/.$(@F).tmp else - $(CC) $(CFLAGS) -c $< -o $@ + $(CC) $(c_flags) -c $< -o $@ endif %.o: %.S Makefile - $(CC) $(AFLAGS) -c $< -o $@ + $(CC) $(a_flags) -c $< -o $@ $(filter %.init.o,$(obj-y) $(obj-bin-y) $(extra-y)): %.init.o: %.o Makefile $(OBJDUMP) -h $< | sed -n '/[0-9]/{s,00*,0,g;p;}' | while read idx name sz rest; do \ @@ -205,12 +204,12 @@ $(filter %.init.o,$(obj-y) $(obj-bin-y) $(extra-y)): %.init.o: %.o Makefile $(OBJCOPY) $(foreach s,$(SPECIAL_DATA_SECTIONS),--rename-section .$(s)=.init.$(s)) $< $@ %.i: %.c Makefile - $(CPP) $(filter-out -Wa$(comma)%,$(CFLAGS)) $< -o $@ + $(CPP) $(filter-out -Wa$(comma)%,$(c_flags)) $< -o $@ %.s: %.c Makefile - $(CC) $(filter-out -Wa$(comma)%,$(CFLAGS)) -S $< -o $@ + $(CC) $(filter-out -Wa$(comma)%,$(c_flags)) -S $< -o $@ %.s: %.S Makefile - $(CPP) $(filter-out -Wa$(comma)%,$(AFLAGS)) $< -o $@ + $(CPP) $(filter-out -Wa$(comma)%,$(a_flags)) $< -o $@ -include $(DEPS_INCLUDE) diff --git a/xen/arch/arm/Makefile b/xen/arch/arm/Makefile index 7273f356f190..913f6cdeed3f 100644 --- a/xen/arch/arm/Makefile +++ b/xen/arch/arm/Makefile @@ -120,10 +120,10 @@ $(TARGET)-syms: prelink.o xen.lds rm -f $(@D)/.$(@F).[0-9]* asm-offsets.s: $(TARGET_SUBARCH)/asm-offsets.c - $(CC) $(filter-out -flto,$(CFLAGS)) -S -o $@ $< + $(CC) $(filter-out -flto,$(c_flags)) -S -o $@ $< xen.lds: xen.lds.S - $(CC) -P -E -Ui386 $(AFLAGS) -o $@ $< + $(CC) -P -E -Ui386 $(a_flags) -o $@ $< sed -e 's/xen\.lds\.o:/xen\.lds:/g' <.xen.lds.d >.xen.lds.d.new mv -f .xen.lds.d.new .xen.lds.d diff --git a/xen/arch/x86/Makefile b/xen/arch/x86/Makefile index e954edbc2e0a..1405525105d9 100644 --- a/xen/arch/x86/Makefile +++ b/xen/arch/x86/Makefile @@ -168,7 +168,7 @@ EFI_LDFLAGS += --major-os-version=2 --minor-os-version=0 EFI_LDFLAGS += --major-subsystem-version=2 --minor-subsystem-version=0 # Check if the compiler supports the MS ABI. -export XEN_BUILD_EFI := $(shell $(CC) $(filter-out $(CFLAGS-y) .%.d,$(CFLAGS)) -c efi/check.c -o efi/check.o 2>/dev/null && echo y) +export XEN_BUILD_EFI := $(shell $(CC) $(CFLAGS) -c efi/check.c -o efi/check.o 2>/dev/null && echo y) # Check if the linker supports PE.

The latter will force a rebuild if any options to the executable have changed. if_changed_rule checks dependencies like if_changed, but execute rule_$(1) instead of cmd_$(1) when a target needs to be rebuilt. A rule_ macro can call more than one cmd_ macro. One of the cmd_ macro in a rule need to be call using a macro that record the command line, so cmd_and_record is introduced. It is similar to cmd_and_fixup from Linux but without a call to fixdep which we don't have yet. (We will later replace cmd_and_record by cmd_and_fixup.) Example of a rule_ macro: define rule_cc_o_c $(call cmd_and_record,cc_o_o) $(call cmd,objcopy) endef This needs one of the call to use cmd_and_record, otherwise no .*.cmd file will be created, and the target will keep been rebuilt. In order for if_changed to works correctly, we need to load the .%.cmd files that the macro generates, this is done by adding targets in to the $(targets) variable. We use intermediate_targets to add %.init.o dependency %.o to target since there aren't in obj-y. We also add $(MAKECMDGOALS) to targets so that when running for example `make common/memory.i`, make will load the associated .%.cmd dependency file. Beside the if_changed*, we import the machinery used for a "beautify output". The important one is when running make with V=2 which help to debug the makefiles by printing why a target is been rebuilt, via the $(echo-why) macro. if_changed and if_changed_rule aren't used yet. Most of this code is copied from Linux v5.4, including the documentation.

AFAIK, we never relinquish memory from dom0. So I am not sure how a large amount of memory in Dom0 would affect the host shutting down.

Other changes are detailed in patches. v3: - new patches that do some cleanup or fix issues - have rework most patches, to have better commit message or change the coding style, or fix issues that I've seen. There were some cases where CFLAGS were missing. See patch notes for details - introduce if_changed*. That plenty of new patches on top of what we had in v2. (those changes ignore CONFIG_LTO=y, I'll see about fixing that later) (There is more to come in order to use fixdep from Linux, but that's not ready) v2.1: - some fixes v2: Rather than taking Kbuild and making it work with Xen, the v2 takes the opposite approach of slowly transforming our current build system into Kbuild. That have the advantage of keeping all the feature we have and making the patches much easier to review. Kconfig update is done in an other patch series. Hi, I have work toward building Xen (the hypervisor) with Linux's build system, Kbuild. The main reason for that is to be able to have out-of-tree build. It's annoying when a build fail because of the pvshim. Other benefit is a much faster rebuild, and `make clean` doesn't take ages, and better dependencies to figure out what needs to be rebuild. So, we are not there yet, but the series already contain quite a few improvement and cleanup. More patches are going to be added to the series.

It is not very handy because a user has to remove the option everytime it is using another command other than compiling the hypervisor. Furthermore, early printk is one of the few odds one that are not using Kconfig. So this is about time to move it to Kconfig. The new kconfigs options allow a user to eather select a UART driver to use at boot time, and set the parameters, or it is still possible to select a platform which will set the parameters. If CONFIG_EARLY_PRINTK is present in the environment or on the make command line, make will return an error. Signed-off-by: Julien Grall Signed-off-by: Anthony PERARD Tested-by: Stefano Stabellini --- Notes: v4: - Add range to EARLY_UART_BASE_ADDRESS so that kconfig won't accept address higher than 4G on ARM_32 - have EARLY_PRINTK_THUNDERX depends on ARM_64 because the default base address is above 4G - Add deprecation warning to the help of the choice of early printk driver/platform. - in early-printk.txt, add that early printk is available with EXPERT. Patch v3 and early where in "xen/arm: Configure early printk via Kconfig" series. v3: - rename EARLY_PRINK to CONFIG_EARLY_PRINTK in makefile here (which select which object to build). - rename EARLY_UART_BAUD_RATE to EARLY_UART_PL011_BAUD_RATE - typos - drop the list of aliases in early-printk.txt. Kconfig choice menu should be enough. - reword early-printk.txt. - rework how EARLY_PRINTK is set to Y and use that instead of a list of all EARLY_UART_* - Add a check to ask user to use Kconfig to set early printk. - rework the possible choice to have all uart driver and platform specific option together. - have added or reword prompt and help messages of the different options. The platform specific option don't have extended help, the prompt is probably enough. (The non-platform specific options have the help message that Julien have written in the first version.) - have made EARLY_UART_INIT dependent on the value of EARLY_UART_PL011_BAUD_RATE so that there is no need to expose _INIT to users. docs/misc/arm/early-printk.txt | 71 ++--- xen/Kconfig.debug | 2 + xen/arch/arm/Kconfig.debug | 289 ++++++++++++++++++ xen/arch/arm/Makefile | 2 +- xen/arch/arm/Rules.mk | 74 +---- xen/arch/arm/arm32/Makefile | 2 +- xen/arch/arm/arm64/Makefile | 2 +- .../minios.cfg => xen/arch/x86/Kconfig.debug | 0 8 files changed, 319 insertions(+), 123 deletions(-) create mode 100644 xen/arch/arm/Kconfig.debug copy stubdom/c/minios.cfg => xen/arch/x86/Kconfig.debug (100%) diff --git a/docs/misc/arm/early-printk.txt b/docs/misc/arm/early-printk.txt index 89e081e51eaf..aa22826075a4 100644 --- a/docs/misc/arm/early-printk.txt +++ b/docs/misc/arm/early-printk.txt @@ -1,64 +1,39 @@ How to enable early printk -Early printk can only be enabled if debug=y.

=?UTF-8?q?Roger=20Pau=20Monn=C3=A9?= Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Instead of generating the CFLAGS in Rules.mk everytime we enter a new subdirectory, we are going to generate most of them a single time, and export the result in the environment so that Rules.mk can use it. The only flags left to be generated are the ones that depend on the targets, but the variable $(c_flags) takes care of that. Arch specific CFLAGS are generated by a new file "arch/*/arch.mk" which is included by the root Makefile. We export the *FLAGS via the environment variables XEN_*FLAGS because Rules.mk still includes Config.mk and would add duplicated flags to CFLAGS. When running Rules.mk in the root directory (xen/), the variable `root-make-done' is set, so `need-config' will remain undef and so the root Makefile will not generate the cflags again. We can't use CFLAGS in subdirectories to add flags to particular targets, instead start to use CFLAGS-y. Idem for AFLAGS. So there are two different CFLAGS-y, the one in xen/Makefile (and arch.mk), and the one in subdirs that Rules.mk is going to use. We can't add to XEN_CFLAGS because it is exported, so making change to it might be propagated to subdirectory which isn't intended. Some style change are introduced in this patch: when LDFLAGS_DIRECT is included in LDFLAGS use of CFLAGS-$(CONFIG_INDIRECT_THUNK) instead of ifeq(). There is on FIXME added about LTO build, but since LTO is marked as BROKEN, this commit doesn't attempt to filter -flto flags out of the CFLAGS. Signed-off-by: Anthony PERARD --- Notes: v4: - typos - Adding $(AFLAGS-y) to $(AFLAGS) v3: - squash "xen/build: introduce ccflags-y and CFLAGS_$@" here, with those changes: - rename ccflags-y to simply CFLAGS-y and start using AFLAGS-y in subdirs. - remove CFLAGS_$@, we don't need it yet. - fix build of xen.lds and efi.lds which needed -D to be a_flags - remove arch_ccflags, and modify c_flags directly with that change, reorder c_flags, so that target specific flags are last. - remove HAVE_AS_QUOTED_SYM from envvar and check XEN_CFLAGS to find if it's there when adding -D__OBJECT_LABEL__. - fix missing some flags in AFLAGS (like -fshort-wchar in xen/arch/x86/efi/Makefile, and -D__OBJECT_LABEL__ and CFLAGS-stack-boundary) - keep COV_FLAGS generation in Rules.mk since it doesn't invovle to call CC - fix clang test for "asm()-s support .include." (in a new patch done ahead) - include Kconfig.include in xen/Makefile because as-option-add is defined there now. xen/Makefile | 58 +++++++++++++++++++ xen/Rules.mk | 74 +++++++----------------- xen/arch/arm/Makefile | 10 ++-- xen/arch/arm/Rules.mk | 23 -------- xen/arch/arm/{Rules.mk => arch.mk} | 5 -- xen/arch/arm/efi/Makefile | 2 +- xen/arch/x86/Makefile | 24 ++++---- xen/arch/x86/Rules.mk | 91 ++---------------------------- xen/arch/x86/{Rules.mk => arch.mk} | 17 ++---- xen/arch/x86/efi/Makefile | 2 +- xen/common/libelf/Makefile | 4 +- xen/common/libfdt/Makefile | 4 +- xen/include/Makefile | 2 +- xen/xsm/flask/Makefile | 2 +- xen/xsm/flask/ss/Makefile | 2 +- 15 files changed, 115 insertions(+), 205 deletions(-) copy xen/arch/arm/{Rules.mk => arch.mk} (85%) copy xen/arch/x86/{Rules.mk => arch.mk} (87%) diff --git a/xen/Makefile b/xen/Makefile index 8375070e0d41..372692841913 100644 --- a/xen/Makefile +++ b/xen/Makefile @@ -115,6 +115,64 @@ $(KCONFIG_CONFIG): include/config/%.conf include/config/%.conf.cmd: $(KCONFIG_CONFIG) $(MAKE) $(kconfig) syncconfig +ifeq ($(CONFIG_DEBUG),y) +CFLAGS += -O1 +else +CFLAGS += -O2 +endif + +ifeq ($(CONFIG_FRAME_POINTER),y) +CFLAGS += -fno-omit-frame-pointer +else +CFLAGS += -fomit-frame-pointer +endif + +CFLAGS += -nostdinc -fno-builtin -fno-common +CFLAGS += -Werror -Wredundant-decls -Wno-pointer-arith +$(call cc-option-add,CFLAGS,CC,-Wvla) +CFLAGS += -pipe -D__XEN__ -include $(BASEDIR)/include/xen/config.h +CFLAGS-$(CONFIG_DEBUG_INFO) += -g + +ifneq ($(CONFIG_CC_IS_CLANG),y) +# Clang doesn't understand this command line argument, and doesn't appear to +# have an suitable alternative.

This means all macro will be prefix with CONFIG_. We do that ahead of the change. We also take the opportunity to better name some variables, which are used by only one driver and wouldn't make sens for other UART driver. Thus, - EARLY_UART_REG_SHIFT became CONFIG_EARLY_UART_8250_REG_SHIFT - EARLY_PRINTK_VERSION_* became CONFIG_EARLY_UART_SCIF_VERSION_* The other variables are change to have the prefix CONFIG_EARLY_UART_ when they change a parameter of the driver. So we have now: - CONFIG_EARLY_UART_BAUD_RATE - CONFIG_EARLY_UART_BASE_ADDRESS - CONFIG_EARLY_UART_INIT Signed-off-by: Anthony PERARD Acked-by: Julien Grall Tested-by: Stefano Stabellini --- Notes: v4: - cleanup in head.S, removing extra () and space Patch v3 and early where in "xen/arm: Configure early printk via Kconfig" series. v3: - Revert the renaming of EARLY_PRINTK to CONFIG_EARLY_PRINTK in the makefiles, as this doesn't work well with user provided CONFIG_EARLY_PRINTK. This is done in the following patch instead. - rename CONFIG_EARLY_UART_BAUD_RATE to CONFIG_EARLY_UART_PL011_BAUD_RATE xen/arch/arm/Rules.mk | 14 +++++++------- xen/arch/arm/arm32/debug-8250.inc | 2 +- xen/arch/arm/arm32/debug-pl011.inc | 4 ++-- xen/arch/arm/arm32/debug-scif.inc | 4 ++-- xen/arch/arm/arm32/debug.S | 4 ++-- xen/arch/arm/arm32/head.S | 10 +++++----- xen/arch/arm/arm64/debug-8250.inc | 4 ++-- xen/arch/arm/arm64/debug-pl011.inc | 4 ++-- xen/arch/arm/arm64/debug.S | 4 ++-- xen/arch/arm/arm64/head.S | 10 +++++----- xen/include/asm-arm/early_printk.h | 2 +- 11 files changed, 31 insertions(+), 31 deletions(-) diff --git a/xen/arch/arm/Rules.mk b/xen/arch/arm/Rules.mk index 022a3a6f82ba..faa09ea111ec 100644 --- a/xen/arch/arm/Rules.mk +++ b/xen/arch/arm/Rules.mk @@ -66,9 +66,9 @@ endif endif ifeq ($(EARLY_PRINTK_INC),scif) ifneq ($(word 3,$(EARLY_PRINTK_CFG)),) -CFLAGS-y += -DEARLY_PRINTK_VERSION_$(word 3,$(EARLY_PRINTK_CFG)) +CFLAGS-y += -DCONFIG_EARLY_UART_SCIF_VERSION_$(word 3,$(EARLY_PRINTK_CFG)) else -CFLAGS-y += -DEARLY_PRINTK_VERSION_NONE +CFLAGS-y += -DCONFIG_EARLY_UART_SCIF_VERSION_NONE endif endif @@ -77,11 +77,11 @@ EARLY_PRINTK := y endif CFLAGS-$(EARLY_PRINTK) += -DCONFIG_EARLY_PRINTK -CFLAGS-$(EARLY_PRINTK_INIT_UART) += -DEARLY_PRINTK_INIT_UART -CFLAGS-$(EARLY_PRINTK) += -DEARLY_PRINTK_INC=\"debug-$(EARLY_PRINTK_INC).inc\" -CFLAGS-$(EARLY_PRINTK) += -DEARLY_PRINTK_BAUD=$(EARLY_PRINTK_BAUD) -CFLAGS-$(EARLY_PRINTK) += -DEARLY_UART_BASE_ADDRESS=$(EARLY_UART_BASE_ADDRESS) -CFLAGS-$(EARLY_PRINTK) += -DEARLY_UART_REG_SHIFT=$(EARLY_UART_REG_SHIFT) +CFLAGS-$(EARLY_PRINTK_INIT_UART) += -DCONFIG_EARLY_UART_INIT +CFLAGS-$(EARLY_PRINTK) += -DCONFIG_EARLY_PRINTK_INC=\"debug-$(EARLY_PRINTK_INC).inc\" +CFLAGS-$(EARLY_PRINTK) += -DCONFIG_EARLY_UART_PL011_BAUD_RATE=$(EARLY_PRINTK_BAUD) +CFLAGS-$(EARLY_PRINTK) += -DCONFIG_EARLY_UART_BASE_ADDRESS=$(EARLY_UART_BASE_ADDRESS) +CFLAGS-$(EARLY_PRINTK) += -DCONFIG_EARLY_UART_8250_REG_SHIFT=$(EARLY_UART_REG_SHIFT) else # !CONFIG_DEBUG diff --git a/xen/arch/arm/arm32/debug-8250.inc b/xen/arch/arm/arm32/debug-8250.inc index 0759a27ee157..c47e8be4aaf3 100644 --- a/xen/arch/arm/arm32/debug-8250.inc +++ b/xen/arch/arm/arm32/debug-8250.inc @@ -23,7 +23,7 @@ */ .macro early_uart_ready rb rc 1: -

Remove the unnecessary "grep -v '^# [0-9]'". It is to hide the linemarkers generated by the preprocessor. But adding -P inhibit there generation, thus the grep isn't needed anymore. gcc -E -P and clang -E -P have different behavior. While both don't generates linemarkers, gcc also removes all empty lines while clang keep them all. We don't need those empty lines, so we don't generates them in the final compat/%.h headers. (This replace `uniq` which was only de-duplicating empty line.) The only changes in the final generated headers it that they don't have empty lines anymore.

This patch make a change to the way guest_%.o files are built, and now run the same commands that enforce unique symbols. But with patch "xen,symbols: rework file symbols selection", ./symbols should still select the file symbols directive intended to be used for guest_%.o objects. Signed-off-by: Anthony PERARD --- Notes: v4: - remove the introduction of Kbuild's CFLAGS_$@ and simply use make's per-target variable customization. Mostly to avoid using $(eval ) which might not work as expected on make 3.80. xen/arch/x86/mm/Makefile | 14 ++++++++------ xen/arch/x86/mm/hap/Makefile | 15 +++++++++------

So I would rather not follow your suggestion here. Although, I can move the zeroing right before the for loop.

Either the latter macro uses an intermediate variable and ACCESS_ONCE() or, as suggested before, enumerators get arranged such that the check can be done (e.g. using binary masking operations) with a single evaluation of pgc. This may or may not also be an issue for the other two pgc_is_*(), but I think at least for symmetry they should then follow suit. At the very least all three macros need to be immune to uses like page_is_offlined(pg++) or similar argument expressions with side effects. > @@ -1699,19 +1706,18 @@ unsigned int online_page(mfn_t mfn, uint32_t *status) > do { > ret = *status = 0; > > - if ( y & PGC_broken ) > + if ( pgc_is_broken(y) ) > { > ret = -EINVAL; > - *status = PG_ONLINE_FAILED |PG_ONLINE_BROKEN; > + *status = PG_ONLINE_FAILED | PG_ONLINE_BROKEN; > break; > } > - > - if ( (y & PGC_state) == PGC_state_offlined ) > + else if ( pgc_is(y, offlined) ) At the risk of getting flamed again: Even if it was a matter of taste in new code whether to use "else" in a case like this one, this isn't new code, and it is in no way necessary to change what we have for the purpose of this patch.

Also there's no need here for the outer pairs of parentheses. Also, for the next version, may I ask that you number versions in the subject's tag and that you provide a brief description of changes from the previous version (if any, but there ought to be some in a series for there to be a point to send out)?

As you've got two more similar constructs further down in the patch, maybe this also warrants a helper function/macro? > --- a/xen/common/page_alloc.c > +++ b/xen/common/page_alloc.c > @@ -252,6 +252,8 @@ struct bootmem_region { > static struct bootmem_region __initdata > bootmem_region_list[PAGE_SIZE / sizeof(struct bootmem_region)]; > static unsigned int __initdata nr_bootmem_regions; > +static void init_heap_pages(struct page_info *pg, unsigned long nr_pages, > + bool scrub); > > struct scrub_region { > unsigned long offset; > @@ -1390,6 +1392,17 @@ static void free_heap_pages( > ASSERT(order <= MAX_ORDER); > ASSERT(node >= 0); > > + if ( page_state_is(pg, uninitialised) ) > + { > + init_heap_pages(pg, 1 << order, need_scrub); While, at least for now, it shouldn't matter in practice, and while code overall is very inconsistent in this regard, with the respective parameter type being "unsigned long" may I suggest to use 1UL here?

That comment refers us to docs, but I couldn't find anything to this effect in PM Vol 2.

It is necessary in the backport of patch 1, because find_equiv_cpu_id() doesn't have mpbuf->len to hand, and relies on the sentinel to find the end of the table. OTOH, the new logic will cope perfectly well without a sentinel. > >> static struct microcode_patch *cpu_request_microcode(const void *buf, size_t size) >> { >> const struct microcode_patch *saved = NULL; >> struct microcode_patch *patch = NULL; >> - size_t offset = 0, saved_size = 0; >> + size_t saved_size = 0; >> int error = 0; >> - unsigned int cpu = smp_processor_id(); >> - const struct cpu_signature *sig = &per_cpu(cpu_sig, cpu); >> >> - if ( size < 4 || >> - *(const uint32_t *)buf != UCODE_MAGIC ) >> + while ( size ) >> { >> - printk(KERN_ERR "microcode: Wrong microcode patch file magic\n"); >> - error = -EINVAL; >> - goto out; >> - } >> - >> - /* >> - * Multiple container file support: >> - * 1. check if this container file has equiv_cpu_id match >> - * 2.

That doesn't work, because you've got to reset error to 0 somewhere (to avoid it leaking out if you don't find suitable microcode), and it can't be before checking for errors in general.  It can't easily become a conditional because skip_ucode needs setting unconditionally. The only other correct way I can see of arranging this code would be     skip_ucode = error == -ESRCH;     if ( error == -ESRCH )         error = 0;     else if ( error )         break; which doesn't look to be better. I have been debating quite heavily whether -ESRCH is best here, or using -ve, 0 and 1.  However, this doesn't lead to prettier code AFAICT, and gains an ambiguous use for a variable named "error". ~Andrew From xen-devel-bounces@lists.xenproject.org Tue Mar 31 15:27:28 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Tue, 31 Mar 2020 15:27:28 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jJInS-0004Dw-0J; Tue, 31 Mar 2020 15:27:22 +0000 Received: from us1-rack-iad1.inumbo.com ([172.99.69.81]) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jJInP-0004Dr-Pr for xen-devel@lists.xenproject.org; Tue, 31 Mar 2020 15:27:19 +0000 X-Inumbo-ID: 1b94929a-7364-11ea-b4f4-bc764e2007e4 Received: from mx2.suse.de (unknown [195.135.220.15]) by us1-rack-iad1.inumbo.com (Halon) with ESMTPS id 1b94929a-7364-11ea-b4f4-bc764e2007e4; Tue, 31 Mar 2020 15:27:19 +0000 (UTC) X-Virus-Scanned: by amavisd-new at test-mx.suse.de Received: from relay2.suse.de (unknown [195.135.220.254]) by mx2.suse.de (Postfix) with ESMTP id F1019ABC2; Tue, 31 Mar 2020 15:27:17 +0000 (UTC) Subject: Re: [PATCH 11/11] x86/ucode/amd: Rework parsing logic in cpu_request_microcode() To: Andrew Cooper References: <20200331100531.4294-1-andrew.cooper3@citrix.com> <20200331100531.4294-12-andrew.cooper3@citrix.com> <3bcfdf14-7785-0319-26aa-b80926eff7ed@citrix.com> From: Jan Beulich Message-ID: <4e47ddba-d951-d573-1357-199207d28f43@suse.com> Date: Tue, 31 Mar 2020 17:27:12 +0200 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:68.0) Gecko/20100101 Thunderbird/68.6.0 MIME-Version: 1.0 In-Reply-To: <3bcfdf14-7785-0319-26aa-b80926eff7ed@citrix.com> Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: 8bit X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: Xen-devel , Wei Liu , =?UTF-8?Q?Roger_Pau_Monn=c3=a9?= Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" On 31.03.2020 17:19, Andrew Cooper wrote: > On 31/03/2020 16:07, Jan Beulich wrote: >> On 31.03.2020 12:05, Andrew Cooper wrote: >>> @@ -269,55 +265,25 @@ static int apply_microcode(const struct microcode_patch *patch) >>> return 0; >>> } >>> >>> -static int scan_equiv_cpu_table( >>> - const void *data, >>> - size_t size_left, >>> - size_t *offset) >>> +static int scan_equiv_cpu_table(const struct container_equiv_table *et) >>> { >>> const struct cpu_signature *sig = &this_cpu(cpu_sig); >>> - const struct mpbhdr *mpbuf; >>> - const struct equiv_cpu_entry *eq; >>> - unsigned int i, nr; >>> - >>> - if ( size_left < (sizeof(*mpbuf) + 4) || >>> - (mpbuf = data + *offset + 4, >>> - size_left - sizeof(*mpbuf) - 4 < mpbuf->len) ) >>> - { >>> - printk(XENLOG_WARNING "microcode: No space for equivalent cpu table\n"); >>> - return -EINVAL; >>> - } >>> - >>> - *offset += mpbuf->len + CONT_HDR_SIZE; /* add header length */ >>> - >>> - if ( mpbuf->type != UCODE_EQUIV_CPU_TABLE_TYPE ) >>> - { >>> - printk(KERN_ERR "microcode: Wrong microcode equivalent cpu table type field\n"); >>> - return -EINVAL; >>> - } >>> - >>> - if ( mpbuf->len == 0 || mpbuf->len % sizeof(*eq) || >>> - (eq = (const void *)mpbuf->data, >>> - nr = mpbuf->len / sizeof(*eq), >>> - eq[nr - 1].installed_cpu) ) >> Did this last check get lost?

Without it, the end of buffer case happens fine as size becomes 0 and terminates both loops, but in the case that there is a following container, without it we fail because of the "!= UCODE_UCODE_TYPE" check. ~Andrew From xen-devel-bounces@lists.xenproject.org Tue Mar 31 15:47:54 2020 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Tue, 31 Mar 2020 15:47:54 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.89) (envelope-from ) id 1jJJ7H-00064q-Of;

Doesn't the flushing here solely care > about guest translations? Not on AMD, at least to my understanding, the AMD SDM states: "If a hypervisor modifies a nested page table by decreasing permission levels, clearing present bits, or changing address translations and intends to return to the same ASID, it should use either TLB command 011b or 001b." It's in section 15.16.1. This to my understanding implies that on AMD hardware modifications to the NPT require an ASID flush. I assume that on AMD ASIDs also cache combined translations, guest linear -> host physical. In fact without doing such flushes when modifying the nested page tables XenRT was seeing multiple issues on AMD hardware. > > --- a/xen/arch/x86/mm/hap/nested_hap.c > > +++ b/xen/arch/x86/mm/hap/nested_hap.c > > @@ -84,7 +84,7 @@ nestedp2m_write_p2m_entry(struct p2m_domain *p2m, unsigned long gfn, > > safe_write_pte(p, new); > > > > if (old_flags & _PAGE_PRESENT) > > - flush_tlb_mask(p2m->dirty_cpumask); > > + flush_mask(p2m->dirty_cpumask, FLUSH_TLB | FLUSH_HVM_ASID_CORE); > > Same here then I guess. > > > --- a/xen/arch/x86/mm/p2m-pt.c > > +++ b/xen/arch/x86/mm/p2m-pt.c > > @@ -896,7 +896,8 @@ static void p2m_pt_change_entry_type_global(struct p2m_domain *p2m, > > unmap_domain_page(tab); > > > > if ( changed ) > > - flush_tlb_mask(p2m->domain->dirty_cpumask); > > + flush_mask(p2m->domain->dirty_cpumask, > > + FLUSH_TLB | FLUSH_HVM_ASID_CORE); > > Given that this code is used in shadow mode as well, perhaps > better to keep it here.

I think there's indeed room for improvement here, as it's likely possible to drop some of the ASID/VPID flushes. Given that previous to this patch we would flush ASIDs on every TLB flush I think the current approach is safe, and as said above further improvements can be done afterwards. > Also, seeing the large number of conversions, perhaps have another > wrapper, e.g. flush_tlb_mask_hvm(), at least for the cases where > both flags get specified unconditionally? That's fine for me, if you agree with the proposed naming (flush_tlb_mask_hvm) I'm happy to introduce the helper. Thanks, Roger.

I changed the partial DTB and it did not crash anymore. However, I am encountering another problem now: in Dom0 and in dom0less-boo= ted DomUs, I cannot use /dev/hvc0. Even though I'm specifying "console=3Dhvc0" in dom0-bootargs, when dom0 fin= ishes booting, it looks like I cannot use the getty spawned on /dev/hvc0. This is the end of the boot log: [ 2.947845] random: rngd: uninitialized urandom read (4 bytes read) [ 2.958415] random: rngd: uninitialized urandom read (4 bytes read) [ 2.965452] random: rngd: uninitialized urandom read (2500 bytes read) .

Which I do not understand, since Dom0 should not have access (?) directly to ttyL= F0 (the serial console device on our boards). If I remove the line which spawns the getty on ttyLF0 from = /etc/inittab, the system hangs when waiting for the username, and it does not let me type in any character= s. For the record, hvc0 is=20 added to /etc/securetty. In a system where I boot DomU via xl from Dom0, I can switch to its console= with xl console, and hvc0 works there. The problem that comes with this is that I can not use the CTRL-AAA command= to switch between Dom0 console and DomU console in a dom0less case, and I cannot therefore test that the p= assthrough works. But at least Dom0 does not have an entry for it under /dev, anymore, and DomU boot prompt tel= ls that the driver has been registered.

To be honest, it feels wrong to me to have "off" != 0 and use a void type for the handle. Would it make sense to forbid it? As a side node, I have updated __copy_to_guest_offset() but forgot to update copy_to_guest_offset(). I will look to apply the modifications we agree on both side. > > To address this, I guess we need to find an expression along the > lines of that comparison, which does not cause any code to be > generated, but which verifies the properties we care about. The > line you change should be left alone, from all I can tell right > now. I am not aware of any way before C11 to check if a variable is const or not. If we wanted to keep allow void type the handle then a possible approach would be: #define copy_to_guest_offset(hnd, off, ptr, nr) ({ \ const typeof(*(ptr)) *_s = (ptr); \ typeof(*((hnd).p)) *_d = (hnd).p; \ size_t mul = (sizeof(*(hnd).p) > 1) ? 1 : sizeof (*_s); \ ((void)((hnd).p == (ptr))); \ raw_copy_to_guest(_d + (off) * mul, _s, sizeof(*_s)*(nr)); \ }) I don't particularly like it but I could not come up with better so far.

The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.

For dom0less-booted DomUs it is normal because they don't get a PV console, they get an emulated PL011 UART instead. Make sure to have a "vpl011" tag in device tree to enable it (ImageBuilder generates it by default.)

It looks like there is some kind of interference between the dom0 ttyLF0 driver and the Xen serial driver. Is your Xen UART driver marking the device as "used by Xen"? See for instance the pl011 driver, at the end of xen/drivers/char/pl011.c:pl011_dt_uart_init: dt_device_set_used_by(dev, DOMID_XEN); Devices that are marked as "used by Xen" are not exposed to dom0, so you shouldn't see the ttyLF0 device come up in Linux at all.

Signed-off-by: Ian Jackson Reviewed-by: Julien Grall commit b72682c602b8d1aaadca439d49cc79c79dbc17bc Author: Jason Andryuk Date: Thu Mar 12 10:54:17 2020 -0400 scripts: Use stat to check lock claim Replace the perl locking check with stat(1). Stat is able to fstat stdin (file descriptor 0) when passed '-' as an argument. This is now used to check $_lockfd. stat(1) support for '-' was introduced to coreutils in 2009. After A releases its lock, script B will return from flock and execute stat. Since the lockfile has been removed by A, stat prints an error to stderr and exits non-zero. Redirect stderr to /dev/null to avoid filling /var/log/xen/xen-hotplug.log with "No such file or directory" messages. Placing the stat call inside the "if" condition ensures we only check the stat output when the command completed successfully. This change removes the only runtime dependency of the xen toolstack on perl.
