[PATCH net 0/4] netfilter: updates for net

[Florian Westphal <fw@strlen.de>]

Hello,

This series contains fixes for your *net* tree.
First patch, from Phil Sutter, reduces number of audit notifications
when userspace requests to re-set stateful objects.
This change also comes with a selftest update.

Second patch, also from Phil, moves the nftables audit selftest
to its own netns to avoid interference with the init netns.

Third patch, from Pablo Neira, fixes an inconsistency with the "rbtree"
set backend: When set element X has expired, a request to delete element
X should fail (like with all other backends).

Finally, patch four, also from Pablo, reverts a recent attempt to speed
up abort of a large pending update with the "pipapo" set backend.

It could cause stray references to remain in the set, which then
results in a double-free.

The following changes since commit 2915240eddba96b37de4c7e9a3d0ac6f9548454b:
