====================
Netfilter updates for net-next
The following series contains Netfilter updates for net-next:
1) Make legacy xtables configs user selectable, from Breno Leitao.
2) Fix a few sparse warnings related to percpu, from Uros Bizjak.
3) Use strscpy_pad, from Justin Stitt.
4) Use nft_trans_elem_alloc() in catchall flush, from Florian Westphal.
5) A series of 7 patches to fix false positive with CONFIG_RCU_LIST=y.
Florian also sees possible issue with 10 while module load/removal
when requesting an expression that is available via module. As for
patch 11, object is being updated so reference on the module already
exists so I don't see any real issue.
Florian says:
"Unfortunately there are many more errors, and not all are false positives.
First patches pass lockdep_commit_lock_is_held() to the rcu list traversal
macro so that those splats are avoided.
The last two patches are real code change as opposed to
'pass the transaction mutex to relax rcu check':
Those two lists are not protected by transaction mutex so could be altered
in parallel.
This targets nf-next because these are long-standing issues."
