Subject: [PATCH net 0/2] Netfilter fixes for net

Hi,

The following patchset contains late Netfilter fixes for net:

1) Use READ_ONCE()/WRITE_ONCE() to update ct->mark, from Daniel Xu.
   Not reported by syzbot, but I presume KASAN would trigger post
   a splat on this. This is a rather old issue, predating git history.

2) Do not set up extensions for set element with end interval flag
   set on. This leads to bogusly skipping this elements as expired
   when listing the set/map to userspace as well as increasing
   memory consumpton when stateful expressions are used. This issue
   has been present since 4.18, when timeout support for rbtree set
   was added.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git

Thanks.
