This brings the (per-conntrack) ecache extension back to 24 bytes in size (was 152 byte on x86_64 with lockdep on). When event delivery fails, re-delivery is attempted via work queue. Redelivery is attempted at least every 0.1 seconds, but can happen more frequently if userspace is not congested. The nf_ct_release_dying_list() function is removed. With this patch, ownership of the to-be-redelivered conntracks (on-dying-list-with-DYING-bit not yet set) is with the work queue, which will release the references once event is out. Joint work with Pablo Neira Ayuso. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
