>From Ubuntu's POV this is rather new as the code in Mesa came in with the fresh 18.3.0_rc4-1
It is possible that no one else saw it so far ...
It is in mesa upstream since
  https://github.com/mesa3d/mesa/commit/d877451b48a59ab0f9a4210fc736f51da5851c9a

But opinions might differ ...
I'll subscribe upstream qemu to this bug and then post a summary here.
This will mirror the bug updates to the Mailing List, if there is no harsh feedback I'll propose a patch to remove sched_setaffinity from the list of blocked calls.

[Qemu-devel] [Bug 1815889] Re: qemu-system-x86_64 crashed with signal 31 in __pthread_setaffinity_new()

[Christian Ehrhardt ]

Summary:
- qemu crash when using GL
- "sched_setaffinity" is the syscall that is seccomp blocked and kills qemu
- the mesa i915 drivers (and your radeon as well) will do that call
- it is blocked by the current qemu -sanbox on,...,resourcecontrol=deny which is libvirts default
- Implemented by qemu 24f8cdc572
- Similar issue being fixed last year qemu 056de1e894
- new code in mesa 18.3 since mesa d877451b48

I think we just need to allow sched_setaffinity with these new mesa drivers in the wild.
The alternative to detect gl usage in libvirt and only then allow ressourcecontrol IMHO seems over-engineered (needs internals to actually pass the need of seccomp subsets to be switched) and not better (more syscalls will be non-blocked then as the -secomp interface isn't fine grained).

OTOH the man page literally says "... Disable process affinity ...", so I'm not sure we can just remove it. Maybe split resourcecontrol in two, put *affinity* in the new one and make the default being not blocked - so that upper layers like libvirt will work until one explicitly states ... -sandbox on,affinity=on which no one wanting to use GL would do. That again seems too much.
Well the discussion will happen either here on ML/bug or latter when submitting an RFC for it.

[Daniel Berrange]

IMHO that mesa change is not valid. It is settings its affinity to run
on all threads which is definitely *NOT* something we want to be
allowed.  Management applications want to control which CPUs QEMU runs
on, and as such Mesa should honour the CPU placement that the QEMU
process has.

This is a great example of why QEMU wants to use seccomp to block
affinity changes to prevent something silently trying to use more CPUs
than are assigned to this QEMU.

[Qemu-devel] [Bug 1815889] Re: qemu-system-x86_64 crashed with signal 31 in __pthread_setaffinity_new()

[elmarco]

(I reported that issue a few days ago too:
https://lists.gnu.org/archive/html/qemu-devel/2019-02/msg06066.html)

Perhaps we can teach mesa to not change CPU affinity (some option, or
environment variable, or seccomp check).

Daniel, when virgl/mesa will be running in a separate process (thanks to
vhost-user-gpu), I suppose the rendering process will be free to change
the CPU affinity. Does that make a difference if mesa thread is in qemu
or a separate process, in this case?

[Daniel Berrange]

As & when libvirt & QEMU supports the external vhost processes for this
I expect it will still restrict the CPU affinity and apply seccomp
filters that likely to be as strict as they are today at minimum.

[Qemu-devel] [Bug 1815889] Re: qemu-system-x86_64 crashed with signal 31 in __pthread_setaffinity_new()

[Daniel Berrange]

I did wonder if we could set the action for some syscalls to be "errno"
instead of "kill process", but I worry that could then result in silent
mis-behaviour as processes fail to check return value as they blindly
assume the call cannot fail.

We should probably talk with mesa developers about providing a config
option to prevent this affinity change. An env variable is workable if
there's no other mechanism they can expose.

Thanks Daniel and MarcAndre for chiming in here.
Atfer thinking more about it I agree to Daniel that actually mesa should honor and stick with its affinity assignment.

For documentation purpose: the solution proposed on the ML is at https://lists.freedesktop.org/archives/mesa-dev/2019-February/215926.html
I also added a bug tracker to the fredesktop bug as task.

[Christian Ehrhardt ]

@Ubuntu-Desktop Team (now subscribed) - is there a chance we can revert [1] in mesa before it will be released with Disco for now. That would be needed until an accepted solution throughout the stack of libvirt/qemu/mesa is found?
Otherwise using GL backed qemu graphics will fail as outlined in the bug.

Once such a cross-package solution to the problem is found we can (if
needed at all) SRU back the set of changes to all components required.

Since upgrading Mesa from 18.2 to 18.3, launching a QEMU virtual machine
with Spice OpenGL enabled (for virgl), causes QEMU to crash with SIGSYS
inside the radeonsi driver. The reason for this is that the QEMU sandbox

called in pthread_setaffinity_np, which is now used by the radeonsi
driver.

A simple way to reproduce this problem is:

Since setting the thread affinity seems non-essential here, the failing syscall should be handled gracefully, for example by setting a signal handler to ignore the SIGSYS signal.

I'm curious what motivated this change to start with ?  Even if QEMU was
not enforcing seccomp filters, I think I'd consider it a bug for mesa to
be setting its process affinity in this way.  The mgmt application or
sysadmin has decided that the process must have a certain affinity,
based on how it/they want the host CPUs utilized. Why is mesa wanting to
override this administrative policy decision to restrict CPU usage ?

The correct solution is to fix pthread_setaffinity such that it returns
an error code instead of crashing.

An even better solution would be to have a virtual thread affinity that
only the application can see and change, which should be silently masked
by administrative policies not visible to the application.

Mesa doesn't really need explicit thread affinity at all. All it wants
is that certain sets of threads run on the same CPU module; it doesn't
care which particular CPU module that is. What's really needed is an API
to express this affinity between threads, instead of to specific CPU
cores.

Maybe it should, at least when using the spawn=deny option, but currently it doesn't. That option only blocks the fork, vfork and execve syscalls, but glibc's fork() function uses the clone syscall, and thus continues to work.
However, that behavior might be different when using other C library implementations, so it wouldn't be correct to rely on this.
One could use clone() instead of fork(), but future versions of qemu might block the clone syscall, as well.

Unfortunately, I'm not aware of a proper solution for this bug short of
adding a new API to the kernel.

You can test 19.0~rc6 with this reverted on a ppa:

ppa:canonical-x/x-staging

[Christian Ehrhardt ]

Hi Timo,
I tried to test with the mesa from ppa:canonical-x/x-staging
But there is a dependency issue in that PPA - I can't install all packages from there.
It seems most of the X* packages will need a transition for the new mesa and those are not in this ppa right now.

Installing all that I can from the PPA doesn't resolve the issue, is
there something more you need to upload to the PPA - or are there other
things I'd need to do to install all of mesa?

This is the current mix of rc5/6 it gave me :-/

I don't have that issue on a chroot, so you should at least tell me why
it would refuse to upgrade them all.. apt should show an error

The PPA was built against -proposed so I had to enable that to install all libs.
That done the 19.0.0~rc6-1ubuntu0.1 with the set affinity change reverted works quite nicely.

It would be great to get that into Ubuntu 19.04 until the involved
upstreams agreed how to proceed with it and we can then sort out what to
do in which package. Which after all might be after cutoff and in 19.10
then.

Thanks Timo, let me know if you need another verification on this at any
point to drive it into 19.04.

[Baker-dylan-c]

I'm removing this from the 19.0 blocking tracker. Generally we don't add
bugs to block a release if they were present in the previous release,
additionally there doesn't seem to be any consensus on a solution, at
this moment. If there is a fix implemented I'd be happy to pull that
into a later 19.0 release.

I think the thread affinity API is a correct way to optimize for CPU
cache topologies. pthread is a basic user API. Security policies
shouldn't disallow pthread functions.

FYI the QEMU change merged in the following pull request changed to
return an EPERM errno for the thread affinity syscalls:

commit 12f067cc14b90aef60b2b7d03e1df74cc50a0459

Author: Peter Maydell <peter.maydell@linaro.org>

    Merge remote-tracking branch 'remotes/otubo/tags/pull-seccomp-20190327' into staging
    
    pull-seccomp-20190327

      seccomp: don't kill process for resource control syscalls
    
    Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

IOW, mesa's usage of this syscalls will still be blocked, but it will no
longer kill the process.

Thank you Daniel,
we will most likely keep Disco as-is for now and merge this in 19.10 where then mesa can drop the revert. I tagged it for 19.10 to be revisited.
