Title:
xfrm interface: fix oops when deleting a x-netns interface
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
When a netns is removed, it may corrupt x-netns xfrm interfaces that
have their link part in this netns. It will later trigger an oops when
those interfaces are removed.
This problem has been fixed in the upstream commit c95c5f58b35e ("xfrm
interface: fix oops when deleting a x-netns interface"):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c95c5f58b35e
[Test Case]
The steps to reproduce the oops is explained in the commit log of the
upstream patch.
[Regression Potential]
The patch affects only the xfrm interface driver, more precisely, the
deletion part. Thus, the potential regressions are limited to this
area.
