Subject: [PATCH net 0/6] Netfilter fixes for net

Hi,

The following patchset contains Netfilter fixes for net:

1) Incorrect nf_defrag registration for bpf link infra, from D. Wythe.

2) Skip inactive elements in pipapo set backend walk to avoid double
   deactivation, from Florian Westphal.

3) Fix NFT_*_F_PRESENT check with big endian arch, also from Florian.

4) Bail out if number of expressions in NFTA_DYNSET_EXPRESSIONS mismatch
   stateful expressions in set declaration.

5) Honor family in table lookup by handle. Broken since 4.16.

6) Use sk_callback_lock to protect access to sk->sk_socket in xt_owner.
   sock_orphan() might zap this pointer, from Phil Sutter.

All of these fixes address broken stuff for several releases.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git nf-23-12-06

Thanks.
