5.15.0-58.64 breaks xen bridge networking (pvh domU)

[Sébastien Chaumat]

[Impact]
Xen guests will not have network access. This fixes a regression due to the fix
for CVE-2022-3643.

[Testing]
This has only been build-tested.

[Potential regression]
Xen guests might not have network access.
----------------------------------------------------------------------

With 5.15.0-58.64-generic, bridge networking on xen is broken :

 no packet (check with tcpdump) flowing between dom0 and any domUs
attached to a network bridge.
 downgrading to 5.15.0-57-generic fix the issue. Thus the patch to the netback driver seems the cause.

relevant network config :

brtctl show :
br0 8000.XXXXXXXXXXX no eno1
       vif1.0

relevant domU config :

kernel = '/usr/lib/grub-xen/grub-i386-xen_pvh.bin'
type = 'pvh'

vif = [ 'ip=192.168.10.10 ,bridge=br0' ]

No message in dmesg, journal, xen logs..

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2002889

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

It
works in 5.15.0-56-generic.

It looks like you included
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/xen-netback?h=linux-5.15.y&id=0fe29bd92594a747a2561589bd452c259451929e
to fix CVE-2022-3643.

Unfortunately, that commit had issues and needed a fixup:
https://<email address hidden>/T/#t

The 5.15.y version of that patch is in stable here:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/xen-netback?h=linux-5.15.y&id=dec5abd91abc700dcb869f8056bc1f48d045ff97

Looking at http://launchpadlibrarian.net/644373416/linux_5.15.0-56.62_5.15.0-58.64.diff.gz
, it looks like dec5abd91abc700dcb869f8056bc1f48d045ff97 is missing.

[Klaus Darilion (klausdarilion)]

Hello!

I hit the same bug. The problem is an incomplete backport for XSA-423.

Here is the same bugreport from debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1026035

http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_5.15.0-58.64/changelog mentions
" * CVE-2022-3643
    - xen/netback: Ensure protocol headers don't fall in the non-linear area"

but this is incomplete. Also this commit must be backported:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/xen-netback?h=v5.15.90&id=dec5abd91abc700dcb869f8056bc1f48d045ff97

IMO this is critical, as this regression breaks networking for XEN VMs.

[Klaus Darilion (klausdarilion)]

It seems the second part of the CVE-fix is also missing in bionic, focal and kinetic kernel sources.

[Jan Kellermann (jan-kellermann)]

We are affected on live machines too.

[Stefan Bader (smb)]

For Jammy applied as v5.15.83 (additional reference added now)

[Stefan Bader (smb)]

For Focal applied as v5.4.227 (additional reference added now)

[Simon Déziel (sdeziel)]

A user on #ubuntu-server reported being affected by this bug as well but on Focal with the HWE kernel 5.15. I'm not sure how to do verification in such case? Should they manually pull the .deb from jammy-proposed or will there be a HWE kernel built for focal-proposed?

[Luke Nowakowski-Krijger (lukenow)]

@Simon There is a 5.15 hwe kernel in focal proposed that can be installed and tested. The exact kernel version with this fix should be 5.15.0-66.73~20.04.1 . Let me know if there is any trouble with that / with the user.

[Jan Kellermann (jan-kellermann)]

On Ubuntu 22.04 5.15.0-66 from jammy proposed solves this problem. Thank you very much.

[Jan Kellermann (jan-kellermann)]

Ob Ubuntu 20.04 with linux-generic-hwe-20.04 (5.15.0.66.73~20.04.27) from focal proposed solves the problem. Thank you very much.

[Jan Kellermann (jan-kellermann)]

On Ubuntu 20.04 with the Kernel 5.4.0-144 the problem did not occur (I did not test if problem exists on previuos 5.4-kernel).
Thank you very much.

[Jan Kellermann (jan-kellermann)]

Bionic:
The problem does **not** occur on Ubuntu 18.04 with HWE-kernel 5.4.0-137 (-138 I did not test, sorry)
The problem does **not** occur on Ubuntu 18.04 with HWE-kernel 5.4.0-139 > fixed!

Thank you very much!

[Oliver Linden (oliver-linden)]

I can confirm Jan Kellermann's findings on ubuntu 20.04 with linux-generic-hwe-20.04 that version 5.15.0.66.73~20.04.27 from focal proposed solves the problem. Thank you so much.
