parentnetfilter: remove unused "config IP_NF_QUEUE" (diff)
Merge branch 'master' of git://1984.lsi.us.es/nf
Pablo Neira Ayuso says: ==================== The following patchset contains 7 Netfilter/IPVS fixes for 3.9-rc, they are: * Restrict IPv6 stateless NPT targets to the mangle table. Many users are complaining that this target does not work in the nat table, which is the wrong table for it, from Florian Westphal. * Fix possible use before initialization in the netns init path of several conntrack protocol trackers (introduced recently while improving conntrack netns support), from Gao Feng. * Fix incorrect initialization of copy_range in nfnetlink_queue, spotted by Eric Dumazet during the NFWS2013, patch from myself. * Fix wrong calculation of next SCTP chunk in IPVS, from Julian Anastasov. * Remove rcu_read_lock section in IPVS while calling ipv4_update_pmtu not required anymore after change introduced in 3.7, again from Julian. * Fix SYN looping in IPVS state sync if the backup is used a real server in DR/TUN modes, this required a new /proc entry to disable the director function when acting as backup, also from Julian. * Remove leftover IP_NF_QUEUE Kconfig after ip_queue removal, noted by Paul Bolle. ==================== Signed-off-by: David S.
