Hi Bertrand,

Thank you for the reply.

It seems that you host pyth= on is used instead of the one compiled by Yocto.

With python2.7 also we are = facing the same issue

- which version of Yocto yo= u are using
    poky-2.1= .2

- what layers you included<= /span>
  meta-virtualization<= /span>

- what parameters did you s= et in your local.conf
   Please find th= e attached local.conf for your reference
 
- what image you are buildi= ng ?
  core-image-weston

when executing pygrub we are getting the below error:
Tra=
ceback (most recent call last):=0A=
   File "/usr/lib/xen/bin/pygrub", line 20, in <modu=
le>=0A=
     import xen.lowlevel.xc=0A=
ImportError: No module named xen.lowlevel.xc

Thank you,
Deepthi

Could you tell me:
- which version of Yocto you are using
- what layers you included
- what parameters did you set in your local.conf
- what image you are building ?

I having been staring at this problem for days now and I just don't see it. Last thing I tried was to build a VM on the "failing" hypervisor, confirm that it would not boot, move it to the "working hypervisor", and confirm that it would boot. So, that argues that the build is fine. It is something I am not getting correct in the hypervisor configuration. I could really use some suggestions for things to try.

You should consider using a bootloader like pvgrub2 or pygrub so that you can use the boot configuration of the domU. Note that from 20.04, Ubuntu switched to LZ4-compressed kernels and unless you have a very recent version of Xen it won't be able to decompress these for direct kernel boot. From Ubuntu 20.04 you can use PVH mode and pvhgrub on any version of Xen that supports PVH mode.

Yes, the 20.04 problem is why I started down the road of using FAI to build the VMs. I was having problems getting xen tools to build bootable 20.04 domu. Likely my own problem, but I am a lot more familiar with FAI then xen-tools. Thanks for helping get moving again. In spite of the fact that I wear glasses I often find that 4 eyes is not enough for me to see what is in front of my face.

Newer 5.10 kernels give me some other error,  to do with interrupts. Seems interrupts vectors point to La-La-Land, or else they are routed to the wrong CPU. I'm fairly certain I did not have this issue running Xen-4.14-staging with the earliest linux-5.10.x, but that had other issues. File-system corruption got me a week around christmas with the whole system down :- ( . Allowed me to learn how to use bacula from a grml rescue cd without a  catalog-database :-) . The stalls happen under load (net or cpu, don't know which matters more). I can reliably reproduce if i run a lot of compilations& network fetches in the domu while simultaneously lanunching firefox and thunderbird. I have home mounted with nfs from the dom0, so lots of traffic when thunderbird and firefox launch. On occation the stalls are caught by the kernel, and I get a stack-trace, but I guess those are consequences of the network stall, incidental to the real issue. like: Feb 15 09:09:38 gt kernel:     status: r Feb 15 09:09:38 gt kernel: net_ratelimit: 5 callbacks suppressed Feb 15 09:09:38 gt kernel: net eth0: rx->offset: 0, size: -1 Feb 15 09:09:38 gt root[45567]: ACPI event unhandled: jack/lineout LINEOUT unplug Feb 15 09:09:38 gt root[45570]: ACPI event unhandled: jack/videoout VIDEOOUT unplug Feb 15 09:09:44 gt kernel: net eth0: rx->offset: 0, size: -1 Feb 15 09:09:57 gt kernel: net eth0: rx->offset: 0, size: -1 Feb 15 09:10:01 gt CROND[45682]: (root) CMD (/usr/lib/sa/sa1 1 1) Feb 15 09:10:23 gt kernel: net eth0: rx->offset: 0, size: -1 Feb 15 09:11:17 gt kernel: net eth0: rx->offset: 0, size: -1 Feb 15 09:11:58 gt kernel: INFO: task IndexedDB #3:45442 blocked for more than 122 seconds.

Hi Bertrand,

I switched all the meta layers to Rocko but meta-demo/meta-rcar-gen3-xen is= master branch. I got the following error.

This is a very old release (4 to 5 years old) and it is not supported anymo= re.

Since this was written it could really be that Renesas updated their suppor= t so you might try to check an newer version of the gen3 support:

and use the corresponding version of meta-virtualization.

There are some patches for pygrub on meta-virtualization master that you mi= ght want to look at:

Hello Bertrand,

As per your suggestion I removed .bbappend and my build is going on.

Thank you,

It seems your meta-demo is dependent on an older kernel version.

You should try to contact the maintainer of this meta-demo layer or you wil= l have to either try to:
- remove this bbappend as it could be that it is not needed anymore
- port the things it does to the current version of the linux-renesas

Cheers
Bertrand

Below is the entire console log from the domU. Anybody know what I should do with this? Currently downgraded the domU to linux-5.4.98, dom0 seems happy on all the available kernels from gentoo (gentoo-sources) from 4.x to 5.11.0. Should also note that I use some unsavory pci-passthrough practices to give each of two domUs their own USB-adapter. --------log:--------- Parsing config from /etc/xen/gt.hvm got a tsc mode string: "native" libxl: warning: libxl_dm.c:1981:libxl__build_device_model_args_new: Domain 7:Only 4 emulated IDE disks are supported.

Linux: grant mapping error handling issues Message-Id: Date: Tue, 16 Feb 2021 12:35:29 +0000 --=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-2021-26932 / XSA-361 version 4 Linux: grant mapping error handling issues UPDATES IN VERSION 4 ==================== Public release. ISSUE DESCRIPTION ================= Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. IMPACT ====== A malicious or buggy frontend driver may be able to crash the corresponding backend driver, causing a denial of service potentially affecting the entire domain running the backend driver. A malicious or buggy frontend driver may be able to cause resource leaks in the domain running the corresponding backend driver, leading to a denial of service. VULNERABLE SYSTEMS ================== All Linux versions back to at least 3.2 are vulnerable, when running in PV mode on x86 or when running on Arm. On x86, only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. MITIGATION ========== On x86, running the backends in HVM or PVH domains will avoid the vulnerability. For protocols where other, e.g. non-kernel-based backends are available, reconfiguring guests to use alternative (e.g. qemu-based) backends may allow to avoid the vulnerability as long as these backends don't rely on similar functionality provided by the xen-gntdev (/dev/gntdev) driver. In all other cases there is no known mitigation. CREDITS ======= This issue was discovered by Jan Beulich of SUSE. RESOLUTION ========== Applying the attached patches resolves this issue. xsa361-linux-1.patch Linux 5.11-rc - 3.19 xsa361-linux-2.patch Linux 5.11-rc - 3.15 xsa361-linux-3.patch Linux 5.11-rc - 4.19 xsa361-linux-4.patch Linux 5.11-rc - 4.19 xsa361-linux-5.patch Linux 5.11-rc - 4.4 $ sha256sum xsa361* bb00ab6319b4fc536566af50c73e064f10f8b99eaa6b0f0b35a8d174c285a905 xsa361-linux-1.patch 73b6a54aa3773ce11f0de6b9aa1d80dd7f4c297dc71924b1a3886bc3b99ac859 xsa361-linux-2.patch 8e554cfab8cdb4fe1b74601a9432ea4c570f74a952ad757f9294ba1666cbeaea xsa361-linux-3.patch 8c290895d10fc148f99e2a6587811b3037f29c3a0201d69d448ff520cea6f96d xsa361-linux-4.patch 231ae3e1b9bec1b75dbbbee4b5acff620ef7ac2853332aa7b3c4957c6ca7f341 xsa361-linux-5.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. Deployment of the mitigation to switch to HVM / PVH backend domains is also permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. HOWEVER, deployment of the non-kernel-based backends mitigation described above is NOT permitted during the embargo on public-facing systems with untrusted guest users and administrators. This is because such a configuration change may be recognizable by the affected guests. AND: Distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable. This is to enable the community to have oversight of the Xen Project Security Team's decisionmaking.)

ISSUE DESCRIPTION ================= To service requests, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case internal state would be insufficiently updated, preventing safe recovery from the error. IMPACT ====== A malicious or buggy frontend driver may be able to crash the corresponding backend driver, potentially affecting the entire domain running the backend driver. In configurations without driver domains or similar disaggregation, that is a host-wide denial of sevice. Privilege escalation and information leaks cannot be ruled out. VULNERABLE SYSTEMS ================== Linux versions from at least 3.11 onwards are vulnerable. MITIGATION ========== Reconfiguring guests to use alternative (e.g. qemu-based) backends may avoid the vulnerability.

ISSUE DESCRIPTION ================= On Arm, a guest is allowed to control whether memory access bypass the cache. This means that Xen needs to ensure that all writes (such as the ones during scrubbing) have reached memory before handing over the page to a guest. Unfortunately the operation to clean the cache happens before checking if the page was scrubbed. Therefore there is no guarantee when all the writes will reach the memory. IMPACT ====== A malicious guest may be able to read sensitive data from memory that previously belonged to another guest. VULNERABLE SYSTEMS ================== Xen version 4.9 onwards are vulnerable. Only Arm systems are vulnerable. MITIGATION ========== There is no known mitigation. CREDITS ======= This issue was discovered by Julien Grall of Amazon. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. Note that patches for released versions are generally prepared to apply to the stable branches, and may not apply cleanly to the most recent release tarball. Downstreams are encouraged to update to the tip of the stable branch before applying these patches. xsa364.patch xen-unstable - 4.11 $ sha256sum xsa364* c9dcb3052bb6ca4001e02b3ad889c70b4eebf1931bef83dfb7de86452851f3c8 xsa364.meta dc313c70bb07b4096bbc4612cbbc180589923277411dede2fda37f04ecc846d6 xsa364.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or mitigations described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators.

charset="utf-8" Content-Disposition: inline Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Xen Security Advisory CVE-2021-26931 / XSA-362 version 3 Linux: backends treating grant mapping errors as bugs UPDATES IN VERSION 3 ==================== Public release. ISSUE DESCRIPTION ================= Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests, like out of memory conditions, it isn't correct to assume so. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. IMPACT ====== A malicious or buggy frontend driver may be able to crash the corresponding backend driver, potentially affecting the entire domain running the backend driver. VULNERABLE SYSTEMS ================== Linux versions from at least 2.6.39 onwards are vulnerable, when run in PV mode. Earlier versions differ significantly in behavior and may therefore instead surface other issues under the same conditions. Linux run in HVM / PVH modes is not vulnerable. MITIGATION ========== For Linux, running the backends in HVM or PVH domains will avoid the vulnerability. For protocols where non-Linux-kernel based backends are available, reconfiguring guests to use alternative (e.g. qemu-based) backends may allow to avoid the vulnerability. In all other cases there is no known mitigation. CREDITS ======= This issue was discovered by Jan Beulich of SUSE. RESOLUTION ========== Applying the appropriate attached patches resolves this issue. Applying the attached patches resolves this issue. xsa362-linux-1.patch Linux 5.11-rc - 5.10 xsa362-linux-2.patch Linux 5.11-rc - 3.16 xsa362-linux-3.patch Linux 5.11-rc - 4.1 $ sha256sum xsa362* d64334807f16ff9909503b3cc9b8b93fd42d2c36e1fb0e508b89a765a53071a8 xsa362-linux-1.patch b6d02952e7fbede55b868cb2dc4d8853284996883dc72518a0cd5b14d6c7fdd4 xsa362-linux-2.patch 0a2661380d8f786fefe12e5a8b1528d4a79f1ad058c26b417c52449a7e16a302 xsa362-linux-3.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. Deployment of the mitigation to switch to HVM / PVH backend domains is also permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. HOWEVER, deployment of the non-kernel-based backends mitigation described above is NOT permitted during the embargo on public-facing systems with untrusted guest users and administrators. This is because such a configuration change may be recognizable by the affected guests. AND: Distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable. This is to enable the community to have oversight of the Xen Project Security Team's decisionmaking.)

charset="utf-8" Content-Disposition: inline Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Xen Security Advisory XSA-366 missed flush in XSA-321 backport ISSUE DESCRIPTION ================= An oversight was made when backporting XSA-320, leading entries in the IOMMU not being properly updated under certain circumstances. IMPACT ====== A malicious guest may be able to retain read/write DMA access to frames returned to Xen's free pool, and later reused for another purpose. Host crashes (leading to a Denial of Service) and privilege escalation cannot be ruled out. VULNERABLE SYSTEMS ================== Xen versions up to 4.11, from at least 3.2 onwards, are affected. Xen versions 4.12 and newer are not affected. Only x86 Intel systems are affected. x86 AMD as well as Arm systems are not affected. Only x86 HVM guests using hardware assisted paging (HAP), having a passed through PCI device assigned, and having page table sharing enabled can leverage the vulnerability. Note that page table sharing will be enabled (by default) only if Xen considers IOMMU and CPU large page size support compatible. MITIGATION ========== Suppressing the use of page table sharing will avoid the vulnerability (command line option "iommu=no-sharept"). Suppressing the use of large HAP pages will avoid the vulnerability (command line options "hap_2mb=no hap_1gb=no"). Not passing through PCI devices to HVM guests will avoid the vulnerability. CREDITS ======= This issue was reported as a bug by M. Vefa Bicakci, and recognized as a security issue by Roger Pau Monne of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. Note that patches for released versions are generally prepared to apply to the stable branches, and may not apply cleanly to the most recent release tarball. Downstreams are encouraged to update to the tip of the stable branch before applying these patches. xsa366-4.11.patch Xen 4.11.x $ sha256sum xsa366* 3131c9487b9446655e2e21df4ccf1e003bec471881396d7b2b1a0939f5cbae96 xsa366.meta 8c8c18ca8425e6167535c3cf774ffeb9dcb4572e81c8d2ff4a73fefede2d4d94 xsa366-4.11.patch $ NOTE REGARDING LACK OF EMBARGO ============================== This was reported and debugged publicly, before the security implications were apparent. -----BEGIN PGP SIGNATURE----- iQFABAEBCAAqFiEEI+MiLBRfRHX6gGCng/4UyVfoK9kFAmAuU5EMHHBncEB4ZW4u b3JnAAoJEIP+FMlX6CvZMCkIAKq1dU6xOMN3lFqY6LeIV+Pn+JQDvJKhDT+lJT9b KAP+a44ks5bHHSD6CPyiq5boU5APE7yqiyJnXBycXVDLH6GGjh7uBvc6A00YkeHU y08l8jxa6/FAyrvCj5P0pYItALwH0NZDtfUE57ueloYUu3KJnyBRtl9icvx/sCa9 CUkpKDpS0te+Rk+G57UPDjGvSPwpIh01vphJ5tyf+2Lrk8rsHTJYWQ7eD8A09jCr DtSD6FylzEuGGY30vPGLUzXgOm8Nji/WgnXnmmbILCEo8PQs3CcoxN53/F8cYvr6 NRERHKZFhHoLmUUCImoFcApxzzdt11USDnCdEXiAkrEOYsk= =w9OA -----END PGP SIGNATURE----- --=separator Content-Type: application/octet-stream;

charset="us-ascii" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Hi, I am booting True Dom0-less on Xilinx ZynqMP UltraScale+ using Xen 4.11, taken from https://github.com/Xilinx/xen. The system has 2GB of RAM (0x00000000 - 0x80000000) of which Xen and the = DomU=20 have an allocation of 1.25GB, per this memory map: 1. DomU1: 0x60000000 - 0x80000000 2. DomU2: 0x40000000 - 0x60000000 3. Xen: 0x30000000 - 0x40000000 I am able to support True Dom0-less by means of the patch/hack demonstrat= ed By Stefano Stabellini at https://youtu.be/UfiP9eAV0WA?t=3D1746. I was able to forcefully put the Xen binary at the address range immediat= ely below 0x40000000 by means of modifying get_xen_paddr() - in itself an ugl= y hack. My questions are: 1. Since Xen performs runtime allocations from its heap, it is allocating= =20 downwards from 0x80000000 - thereby "stealing" memory from DomU1. =20 Can I force the runtime allocations to be from a specific address ra= nge? 2. Has the issue of physical memory map address maps been addressed by Xe= n for embedded? Thank you.

One piece of info missing from my previous report: I have been running the backend with Voluntary preemption on in the dom0 kernel. My set-up is basically an organically grown fuzzing machine for xen, and I have several ill-considered settings turned on. Anyway changing the kernel config to what is seen below, and upgrading to linux kernel 5.10.17 fixes my issue. Changelog for linux-5.10.17 pointed me to the main culprit, a dead-lock on xen_netback, but even with that fix in, I still had issues. I figured that turning off preemption would further lessen risk of constipation on the backend, and that seems to be true. ----linux config that works: ---- CONFIG_PREEMPT_NONE=y # CONFIG_PREEMPT_VOLUNTARY is not set # CONFIG_PREEMPT is not set # CONFIG_PREEMPTIRQ_DELAY_TEST is not set [ extra info from previous mail :] > Feb 15 11:12:38 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:38 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:39 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:39 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:40 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:42 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:45 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:12:52 gt kernel: net eth0: rx->offset: 0, size: -1 > Feb 15 11:13:05 gt kernel: net eth0: rx->offset: 0, size: -1 > > On occasion, with the longer stalls (~ 5 minutes) I get: > > Feb 15 09:29:04 gt kernel: net_ratelimit: 5 callbacks suppressed > > I have tried this on xen 4.14.0, 4.14.1 and 4.14.2-pre, with various > guest kernels ranging from linux-4.19.170 to the early 5.10.x kernels. > Newer 5.10 kernels give me some other error,  to do with interrupts. > Seems interrupts vectors point to La-La-Land, or else they are routed > to the wrong CPU.

This tree is not an official Xen Project tree. I can provide feedback based on how Xen upstream works, but I don't know for sure if this will apply to the Xilinx tree. For any support, I would recommend to contect Xilinx directly. > The system has 2GB of RAM (0x00000000 - 0x80000000) of which Xen and the DomU > have an allocation of 1.25GB, per this memory map: > 1.

Since Xen performs runtime allocations from its heap, it is allocating > downwards from 0x80000000 - thereby "stealing" memory from DomU1. In theory, any memory reserved for domains should have been carved out from the heap allocator. This would be sufficient to prevent Xen allocating memory from the ranges you described above. Therefore, to me this looks like a bug in the tree you are using. > Can I force the runtime allocations to be from a specific address range? > 2. Has the issue of physical memory map address maps been addressed by Xen for embedded? Xen 4.12+ will not relocate itself to the top of the memory anymore. Instead, it will stay where it was first loaded in memory. I would recommend to ask Xilinx if they can provide you with a more recent tree. > > Thank you. > Dov > The information in this e-mail transmission contains proprietary and business > sensitive information.

That's correct. We want to carve out memory from the heap allocator so it can't be used by Xen. I would recommend to read [1] as we discussed the issue in the greater length about reserving memory.

As of today neither upstream Xen nor the Xilinx Xen tree come with the feature of allowing the specification of an address range for dom0less guests. The only thing that Xilinx Xen allows, which is not upstream yet, is the ability of creating dom0less guests 1:1 mapped using the "direct-map" property. But the memory allocation is still done by Xen (you can't select the addresses). Some time ago I worked on a hacky prototype to allow the specification of address ranges, see: http://xenbits.xenproject.org/git-http/people/sstabellini/xen-unstable.git direct-map-2 from 7372466b21c3b6c96bb7a52754e432bac883a1e3 onward. In particular, have a look at "xen/arm: introduce 1:1 mapping for domUs". The work is not complete: it might not work depending on the memory ranges you select for your domUs. In particular, you can't select top-of-RAM addresses for your domUs. However, it might help you getting started. > > > I am able to support True Dom0-less by means of the patch/hack > > > demonstrated By Stefano Stabellini at > > https://youtu.be/UfiP9eAV0WA?t=1746. > > > > > > I was able to forcefully put the Xen binary at the address range > > > immediately below 0x40000000 by means of modifying get_xen_paddr() - > > in itself an ugly hack. > > > > > > My questions are: > > > 1.

Yeah, this is the main problem that my prototype above couldn't solve.

Fixed erroneous reference to XSA-320; should have read XSA-321. ISSUE DESCRIPTION ================= An oversight was made when backporting XSA-321, leading entries in the IOMMU not being properly updated under certain circumstances. IMPACT ====== A malicious guest may be able to retain read/write DMA access to frames returned to Xen's free pool, and later reused for another purpose. Host crashes (leading to a Denial of Service) and privilege escalation cannot be ruled out. VULNERABLE SYSTEMS ================== Xen versions up to 4.11, from at least 3.2 onwards, are affected. Xen versions 4.12 and newer are not affected. Only x86 Intel systems are affected. x86 AMD as well as Arm systems are not affected. Only x86 HVM guests using hardware assisted paging (HAP), having a passed through PCI device assigned, and having page table sharing enabled can leverage the vulnerability. Note that page table sharing will be enabled (by default) only if Xen considers IOMMU and CPU large page size support compatible. MITIGATION ========== Suppressing the use of page table sharing will avoid the vulnerability (command line option "iommu=no-sharept"). Suppressing the use of large HAP pages will avoid the vulnerability (command line options "hap_2mb=no hap_1gb=no"). Not passing through PCI devices to HVM guests will avoid the vulnerability. CREDITS ======= This issue was reported as a bug by M. Vefa Bicakci, and recognized as a security issue by Roger Pau Monne of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. Note that patches for released versions are generally prepared to apply to the stable branches, and may not apply cleanly to the most recent release tarball.
