Title:
openvswitch: nf_ct_put is called with null pointer
Status in linux package in Ubuntu:
Confirmed
Status in openvswitch package in Ubuntu:
Invalid
Status in linux source package in Jammy:
Fix Committed
Bug description:
Using an openvswitch bridge with conntrack flows causes a kernel
warning trace for every packet. This does not break conntrack
functionality, but causes a big packet forwarding performance
degradation and very noisy and large kernel.log/journal/syslog/etc.
The cause is a regression in the 5.15 LTS kernel. This seems to have
been fixed in mainline 5.15.36, but I don't see the fix in any of the
jammy branches.
Upgrading to mainline 5.15.36 or beyond from the Ubuntu PPA fixes the
problem.
Here is a relevant discussion with reference to the fix applied to mainline:
