====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree. Most relevantly, updates for the nfnetlink_log to integrate with
conntrack, fixes for cttimeout and improvements for nf_queue core, they are:
1) Remove useless ifdef around static inline function in IPVS, from
Eric W. Biederman.
2) Simplify the conntrack support for nfnetlink_queue: Merge
nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it back
to nfnetlink_queue.c
3) Use y2038 safe timestamp from nfnetlink_queue.
4) Get rid of dead function definition in nf_conntrack, from Flavio
Leitner.
5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou MATSUZAWA.
This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that
controls enabling both nfqueue and nflog integration with conntrack.
The userspace application can request this via NFULNL_CFG_F_CONNTRACK
configuration flag.
6) Remove unused netns variables in IPVS, from Eric W. Biederman and
Simon Horman.
7) Don't put back the refcount on the cttimeout object from xt_CT on success.
8) Fix crash on cttimeout policy object removal. We have to flush out
the cttimeout extension area of the conntrack not to refer to an unexisting
object that was just removed.
9) Make sure rcu_callback completion before removing nfnetlink_cttimeout
module removal.
10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and
nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann.
11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is
requested. Again from Ken-ichirou MATSUZAWA.
12) Don't use pointer to previous hook when reinjecting traffic via
nf_queue with NF_REPEAT verdict since it may be already gone. This
also avoids a deadloop if the userspace application keeps returning
NF_REPEAT.
13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris.
14) Consolidate logger instance existence check in nfulnl_recv_config().
15) Fix broken atomicity when applying configuration updates to logger
instances in nfnetlink_log.
16) Get rid of the .owner attribute in our hook object. We don't need
this anymore since we're dropping pending packets that have escaped
from the kernel when unremoving the hook. Patch from Florian Westphal.
17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always
assume RCU read side lock from .call_rcu in nfnetlink. Also from Florian.
18) Use static inline function instead of macros to define NF_HOOK() and
NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann.
