Hi all,
The latest update to src:linux for bullseye (DLA 4404-1) caused a
regression for libvirt (#1124549). This is due to libvirt passing a
previously undefined flag to netlink that is now checked and rejected.
This was fixed in libvirt 7.1.0 (upstream commit 81334002340b) so is not
present in later Debian releases.
Since the kernel change was originally made back in 2022, I don't think
we're going to see a workaround added for the libvirt bug now. So I
propose to reassign this bug to libvirt and apply the upstream fix
there. It is a trivial patch and I have already tested that it fixes
the issue.
Let me know soon if you have any objections to this.
