For Linux to keep track of these mappings, it needs to have a page structure for each one. In practice the number of page structures is usually limited. In PV dom0, a range of pfns are typically set aside at boot ("pre-ballooned") for this purpose; for PVH and Arm dom0s, no memory is set aside to begin with. In either case, when more of this "foreign / grant map pfn space" is needed, dom0 will balloon out extra pages to use for this purpose. Unfortunately, in Linux, there are no limits, either on the total amount of memory which dom0 will attempt to balloon down to, nor on the amount of "foreign / grant map" memory which any individual guest can consume. As a result, a malicious guest may be able, with crafted requests to the backend, to cause dom0 to exhaust its own memory, leading to a host crash; and if this is not possible, it may be able to monopolize all of the foreign / grant map pfn space, starving out other guests. IMPACT ====== Guest may be able to crash domain 0 (Host Denial-of-Service); or may be able to starve out I/O requests from other guests (Guest Denial-of-Service). VULNERABLE SYSTEMS ================== All versions of Linux are vulnerable. All Arm dom0s are vulnerable; on x86, PVH dom0 is generally vulnerable, while PV dom0's vulnerability depends on what, if any, "dom0_mem=" option was passed to Xen. MITIGATION ========== On PV dom0, the amount of "pre-ballooned" memory can be increased by limiting dom0 memory via "dom0_mem=", but avoiding use of the "dom0_mem=max:" form of the command line option, or by making the delta between "actual" and "maximum" sufficiently large. This makes the attack more difficult to accomplish. CREDITS ======= This issue was discovered by Julien Grall of ARM. RESOLUTION ========== Applying the appropriate attached patch resolves the domain 0 memory exhaustion issue. NOTE: This does NOT fix the guest starvation issue. Fixing fixing this issue is more complex, and it was determined that it was better to work on a robust fix for the issue in public. This advisory will be updated when fixes are available. xsa300-linux-5.1.patch Linux 4.4 ... 5.2-rc $ sha256sum xsa300* 9c8a9aec52b147f8e8ef41444e1dd11803bacf3bd4d0f6efa863b16f7a9621ac xsa300-linux-5.1.patch $ NOTE ON LACK OF EMBARGO ======================= The lack of predisclosure is due to a short schedule set by the discoverer, and efforts to resolve the advisory wording. 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. But: 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.

I have installed xen using this method: https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide and not compiling it from the source (i tried multiple times but i got errors while compiling the kernel). To change the scheduler, I read that i have to pass this command sched=credit2 to the hypervisor at boottime and to enable FLASK i have to modify .config file and set XSM_ENABLE and FLASK_ENABLE to "y" My questions are : - Is there a difference between the method i used for installing xen and compiling it fromn the sources? I did not compile xen in the method i used. - How to change the scheduler and enable XM-FLASK, while i am using the installation in the link? - In case this is not possible, can anyone guide me on how to instal it from the source and give me the right kernel? Thank you so much, --0000000000000524f6058d67863c Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

Rewrite for clarity, and to remove most references to dom0. The issue is equally applicable to domU's providing backend services. Add information about the arbitrary limit for userspace backends. ISSUE DESCRIPTION ================= Virtual device backends and device models running in domain 0, or other backend driver domains, need to be able to map guest memory (either via grant mappings, or via the foreign mapping interface). Inside Xen, mapped grants are tracked by the maptrack structure. The size of this structure is chosen during domain creation, and has a fixed upper bound for the lifetime of the domain. For Linux to keep track of these mappings, it needs to have a page structure for each one. In practice the number of page structures is usually limited. In PV guests, a range of pfns are typically set aside at boot ("pre-ballooned") for this purpose. For HVM/PVH and Arm guests, no memory is set aside to begin with. In either case, when more of this "foreign / grant map pfn space" is needed, Linux will balloon out extra pages to use for this purpose. Unfortunately, in Linux, there are no limits, either on the total amount of memory which the domain will attempt to balloon out, nor on the amount of "foreign / grant map" memory which any individual guest can consume. For Linux userspace backends (e.g. QEMU) which use /dev/xen/gnttab or /proc/xen/gnttab, there is an arbitrary mapping limit which, if hit, will prevent further mappings from being established. As a result, a malicious guest may be able to, with crafted requests, cause a backend Linux domain to either: 1) Fill the maptrack table in Xen and/or hit the userspace limit. This will starve I/O from other guests served by the same backend. 2) Balloon out sufficient RAM to cause it to swap excessively, or run completely out of memory. This may starve all operations from the domain, including I/O from other guests, or may cause a crash of the domain. IMPACT ====== Guest may be able to crash backend Linux domains, or starve operations inside the domain, including the processing of guest I/O requests (Guest Denial-of-Service). If the backend is domain 0, which is the most common configuration, then host-wide operations may be starved, or the host may crash (Host Denial-of-Service). VULNERABLE SYSTEMS ================== All versions of Linux are vulnerable. Only Linux guests acting as backend domains for other guests may be exploited. All Arm domains are vulnerable, as are x86 PVH/HVM guests. The vulnerability of x86 PV guests depends on how they were configured at boot. MITIGATION ========== PV guests can be constructed with "pre-ballooned" memory, by building it with maxmem > memory. See `man 5 xl.cfg` for full details of these two parameters. For PV dom0, these are controlled by Xen's "dom0_mem=$X,max:$Y" command line parameter. The larger the difference between memory and maxmem, the more space Linux has to fill with grant/foreign mappings before it will start ballooning out real memory to satisfy further mapping requests. This makes the attack more difficult to accomplish. CREDITS ======= This issue was discovered by Julien Grall of ARM. RESOLUTION ========== Applying the appropriate attached patch resolves the backend memory exhaustion issue. NOTE: This does NOT fix the guest starvation issue.

I agree on this, adding support for the RPi3 interrupt controller would
be quite painful, and also needs to be integrated with the existing
(V)GIC support, which has the potential to introduce regressions.
Plus you need to amend the arch timer code, as this is integrated with
the GIC for virtualisation purposes.
AFAIK the RPi3 is one of the few (if not the only one) ARM64 platform
without a GIC, and given that the RPi4 fixes this, I don't see much hop= e
for upstreaming this kind of change.

If you are desperate for (hardware) virtualisation, KVM supports guests
without a (hardware) GIC (via the QEMU emulation), although this is
slower and less tested. Or you just go for some container solution.

Cheers,
Andre.

I built Xen with y= our CONFIG_EARLY_PRINTK but couldn't meet with success.

That brings me to your point about decent firm= ware. I am using u-boot 2019. Is that good=C2=A0enough?

Thanks,

Not much needed on the Xen side, I got away with a small patch for the
UART. Using CONFIG_EARLY_PRINTK=3D8250,0xfe215040,2 should give you some output even without it:

You need to have some more decent firmware than what is shipped, though.

I succeded at creating a new domain with credit2 scheduler by adding an entry to the file 40-custom. Concerning Flask it is disabled, i tried to add this line GRUB_CMDLINE_XEN=3D"flask=3Denforcing" to the file /etc/default/grub but st= il i cannot get it to work. Is there another solution? or i should add something else? I also have another question concerning communication between domains. As far as i know they work using grant tables, but the structure of xen that i have running on my board(intel E3845) is different than what i see in tutorials. I do not have a source folder for xen so i cannot run make menuconfig command or compile anything, i also do not have the "include" folder and all .h files (expl xenbus.h ) are empty, does this mean that i have to take them from another distribution (i saw this on Ubuntu, but unfortunatly it does not work on my board) and put them inside the debian?or the installation is wrong? Thank you so much for your help!

t= hanks for the reply, i have the Dom0 working with debian 9=C2=A0, but as i = said i did not compile it from the source. I succeded at creating a new dom= ain with credit2 scheduler by adding an entry to the file 40-custom.
=
Concerning Flask it is disabled, i tried to add this line GRUB_CMDLINE= _XEN=3D"flask=3Denforcing" to the file /etc/default/grub but stil i cannot get it to work. Is there anothe= r solution? or i should add something else?
I also have another = question concerning communication between domains. As far as i know they wo= rk using grant tables, but the structure of xen that i have running on my b= oard(intel E3845) is different than what i see in tutorials. I do not have = a source folder for xen so i cannot run make menuconfig command or compile = anything, i also do not have the "include" folder and all .h file= s (expl xenbus.h ) are empty, does this mean that i have to take them from = another distribution (i saw this on Ubuntu, but unfortunatly it does not wo= rk on my board) and put them inside the debian?or the installation is wrong= ?
Thank you so much for your help!

Modifying the .config file only makes a difference when compiling from sour= ce. This describes the purpose of .config if you want to understand more:
https://www.linuxjournal.com/co= ntent/kbuild-linux-kernel-build-system

flask is almost certainly not enabled already, but you should be able to ch= eck for support by running 'sudo xl flask'.

credit2 is supposedly the default in some versions, such as 4.12 for exampl= e.

https://xenbits.xenproje= ct.org/docs/4.12-testing/features/sched_credit2.html

You can check the current scheduler by looking at 'xen_scheduler' i= n the output of 'sudo xl info'.
If the scheduler is not sched2, assuming you're using Debian, look at <= a href=3D"https://wiki.debian.org/Xen#Other_configuration_tweaks" target=3D= "_blank" rel=3D"noreferrer">https://wiki.debian.org/Xen#Other_configuration= _tweaks

If you already have a distribution kernel that works with Xen, you should b= e able to use it as-is.

For Xen, try

https://wiki.xenproject.org/wiki/Compiling= _Xen_From_Source

and let us know.

Dom0-less is a Xen feature that adds a novel approach to static partitioning based on virtualization. It allows multiple domains to start at boot time directly from the Xen hypervisor, decreasing boot times dramatically. Xen userspace tools, such as xl and libvirt, become optional. Dom0-less extends the existing device tree based Xen boot protocol to cover information required by additional domains. Binaries, such as kernels and ramdisks, are loaded by the bootloader (u-boot) and advertised to Xen via new device tree bindings. The audience will learn how to use Dom0-less to partition the system.

Hello,

See Stefano talk from = latest Xen summit:
https://www.youtube.co= m/watch?v=3DOrtV6gyHW74

"This talk= will introduce Dom0-less: a new way of using Xen to build
mixed-criticality solutions. Dom0-less is a Xen feature that adds a
novel approach to static partitioning based on virtualization.= It
allows multiple domains to start at boot time directl= y from the Xen
hypervisor, decreasing boot times dramatic= ally. Xen userspace tools,
such as xl and libvirt, become= optional.
Dom0-less extends the existing device tree bas= ed Xen boot protocol to
cover information required by add= itional domains. Binaries, such as
kernels and ramdisks, = are loaded by the bootloader (u-boot) and
advertised to X= en via new device tree bindings. The audience will
learn = how to use Dom0-less to partition the system. Uboot and device
tree configuration details will be explained to enable the audience t= o
get the most out of this feature. The talk will include= a status
update and details on future plans.

Thanks

Very simply put:

- is anyone still working on this after the firs= t release
- has anyone tried it out and found it eas= y/doable/hard?
- Is it gonna see continuous maintena= nce
- will anyone work on the things listed as limit= ations or is it waiting for contribs. If waiting, has anything been done to= get those?
- Is it supposed to be around for more t= han a year
- Is it seeing some testing so one could = assume it works now, and it works in 3 years

Basically the standard checklist for "you are loo= king at a Xen feature and would like to know if it'll be forgotten abou= t like dozens before"

Hope that helped to understand a few things that are missing at the give= n doc page.

For qcow2, Xen uses a mode called `qdev`, where an instance of QEMU
itself acts as a disk backend; this means that there should be
absolutely no issues with image compatibility, since it's exactly the same code reading the image as in upstream QEMU.=C2=A0 Functionally, it
gets tested regularly and so should have no stability issues.

I'm not sure if anyone has been investing in performance -- perhaps
Paul can comment on that.

Unfortunately I'm not familiar with higher-level tools like xen-tools.<= br> It theoretically shouldn't be difficult to extend xen-tools to build qdisk images.=C2=A0 Below are the commands I have in my own scripts for
creating qcow images:

* Create a disk image:

qemu-img create -f qcow2 "${image}" "${size}"M

* Mount such an image in dom0:

xl block-attach 0 ${blockspec}

Where ${blockspec} is:

"backendtype=3Dqdev,vdev=3D${dev},format=3Dqcow2,target=3D${image}&quo= t;

Then you can use parted to create partitions, and `mount
/dev/${dev}${part}` and populate the filesystem.=C2=A0 (Or not use
partitions if you don't want to.)

After that, the rest of the xen-tools install should Just Work.

Alternately, you could just create the disk as described in the first
step, and boot an installer.

What is the guest OS? Also Debian 10? With the 4.19 kernel in Debian 10, you can use grub2 in combination with PVH.

You need the grub-xen-host package on the dom0, and in the domU you need the grub-xen package. No actual grub install / boot sector etc is
needed, only the config file (remember, it's PVH, not HVM).
