[net,0/6] netfilter updates for net

Hello,

This PR contains nf_tables updates for your *net* tree.
This time almost all fixes are for old bugs:

First patch fixes a 4-byte stack OOB write, from myself.
This was broken ever since nftables was switches from 128 to 32bit
register addressing in v4.1.

2nd patch fixes an out-of-bounds read.
This has been broken ever since xt_osf got added in 2.6.31, the bug
was then just moved around during refactoring, from Wander Lairson Costa.

3rd patch adds a missing enum description, from Phil Sutter.

4th patch fixes a UaF inftables that occurs when userspace adds
elements with a timeout so small that expiration happens while the
transaction is still in progress.  Fix from Pablo Neira Ayuso.

Patch 5 fixes a memory out of bounds access, this was
broken since v4.20. Patch from Kyle Zeng and Jozsef Kadlecsik.

Patch 6 fixes another bogus memory access when building audit
record. Bug added in the previous pull request, fix from Pablo.
