Public bug reported:
When net_prio is used without setting ifpriomap and BFP cgroup is used,
memory may be leaked. This was fixed by upstream commit
090e28b229af92dc5b40786ca673999d59e73056, but it had to be reverted to
fix LP #1886668.
When a real fix for this cgroup BFP crash lands, this patch
** Description changed:
+ [Impact]
+ On systems using cgroups and sockets extensively, like docker, kubernetes,
lxd, libvirt, a crash might happen when using linux 4.15.0-109-generic.
+
+ [Fix]
+ Revert the patch that disables sk_alloc cgroup refcounting when tasks are
added to net_prio cgroup.
** Changed in: linux (Ubuntu)
Status: In Progress => Won't Fix

Title:
Kernel reporting 100% battery, always
Status in linux
Public bug reported:
When net_prio and net_cls cgroups are used, cgroup refcount is bogus, as
it's not incremented anymore, but decremented when sockets are closed.
This might lead to crashes possibly because of use-after-free when
packets are received as shown in LP #1886668.
Cascardo.
** Affe
This is caused by net_cls and net_prio cgroups disabling cgroup BPF and
causing it to stop refcounting when allocating new sockets. Releasing those
sockets will cause the refcount to go negative, leading to the potential
use-after-free.
Though this revert won't prevent the issue from happening as
This bug is missing log files that will aid in diagnosing the problem.

Thank you for taking the time to report this bug and helping to make
Ubuntu better.
Am I right in understanding that this is a host kernel oops? My
understanding of PCIe passthrough is that if you're passing through your
sound card to a VM then the host kernel's sound driver should never
crash, so

After passing through the PCIe card EMU 1212m to a VM (kvm/qemu) and
turning the VM off, I see this in dmesg:

No, I have not tried Windows and I don't have access to one atm...

I already tried that, it V4.1.5 worked with both Ubuntu 18.04 and 20.04. I
put in an earlier comment about this.

Tour kernel does seem to dramatically lower the chances of the touchpad
not working upon reboot if that makes any sense. The newer Ubuntu kernel
is very hit nad miss with the touchpad after reboot.
