Hi,
The following patchset contains Netfilter updates for net-next:
Patch #1 skips transaction if object type provides no .update interface.
Patch #2 skips NETDEV_CHANGENAME which is unused.
Patch #3 enables conntrack to handle Multicast Router Advertisements and
Multicast Router Solicitations from the Multicast Router Discovery
protocol (RFC4286) as untracked opposed to invalid packets.
From Linus Luessing.
Patch #4 updates DCCP conntracker to mark invalid as invalid, instead of
dropping them, from Jason Xing.
Patch #5 uses NF_DROP instead of -NF_DROP since NF_DROP is 0, also from Jason.
Patch #6 removes reference in netfilter's sysctl documentation on pickup
entries which were already removed by Florian Westphal.
Patch #7 removes check for IPS_OFFLOAD flag to disable early drop which allows
to evict entries from the conntrack table, also from Florian.
Patches #8 to #16 updates nf_tables pipapo set backend to allocate the
datastructure copy on-demand from preparation phase, to better deal
with OOM situations where .commit step is too late to fail.
Series from Florian Westphal.
Patch #17 adds a selftest with packetdrill to cover conntrack TCP state
transitions, also from Florian.
Patch #18 use GFP_KERNEL to clone elements from control plane to avoid
quick atomic reserves exhaustion with large sets, reporter refers
to million entries magnitude.
