Subject: [PATCH net 0/7] netfilter updates for net

Hello,

The following contains patches for your *net* tree.

Patch 1, from Pablo Neira Ayuso, fixes a performance regression
(since 6.4) when a large pending set update has to be canceled towards
the end of the transaction.

Patch 2 from myself, silences an incorrect compiler warning reported
with a few (older) compiler toolchains.

Patch 3, from Kees Cook, adds __counted_by annotation to
nft_pipapo set backend type.  I took this for net instead of -next
given infra is already in place and no actual code change is made.

Patch 4, from Pablo Neira Ayso, disables timeout resets on
stateful element reset.  The rest should only affect internal object
state, e.g. reset a quota or counter, but not affect a pending timeout.

Patches 5 and 6 fix NULL dereferences in 'inner header' match,
control plane doesn't test for netlink attribute presence before
accessing them. Broken since feature was added in 6.2, fixes from
Xingyuan Mo.

Last patch, from myself, fixes a bogus rule match when skb has
a 0-length mac header, in this case we'd fetch data from network
header instead of canceling rule evaluation.  This is a day 0 bug,
present since nftables was merged in 3.13.

The following changes since commit 50e492143374c17ad89c865a1a44837b3f5c8226:
