Subject: [PATCH net 0/5] Netfilter fixes for net

Hi,

The following patchset contains fixes for net:

Patch #1 disallows anonymous sets with timeout, except for dynamic sets.
         Anonymous sets with timeouts using the pipapo set backend makes
         no sense from userspace perspective.

Patch #2 rejects constant sets with timeout which has no practical usecase.
         This kind of set, once bound, contains elements that expire but
         no new elements can be added.

Patch #3 restores custom conntrack expectations with NFPROTO_INET,
         from Florian Westphal.

Patch #4 marks rhashtable anonymous set with timeout as dead from the
         commit path to avoid that async GC collects these elements. Rules
         that refers to the anonymous set get released with no mutex held
         from the commit path.

Patch #5 fixes a UBSAN shift overflow in H.323 conntrack helper,
         from Lena Wang.
