Netfilter updates for net-next
The following batch contains Netfilter/IPVS updates for your net-next tree:
1) Simplify log infrastructure modularity: Merge ipv4, ipv6, bridge,
netdev and ARP families to nf_log_syslog.c. Add module softdeps.
This fixes a rare deadlock condition that might occur when log
module autoload is required. From Florian Westphal.
2) Moves part of netfilter related pernet data from struct net to
net_generic() infrastructure. All of these users can be modules,
so if they are not loaded there is no need to waste space. Size
reduction is 7 cachelines on x86_64, also from Florian.
2) Update nftables audit support to report events once per table,
to get it aligned with iptables. From Richard Guy Briggs.
3) Check for stale routes from the flowtable garbage collector path.
This is fixing IPv6 which breaks due missing check for the dst_cookie.
4) Add a nfnl_fill_hdr() function to simplify netlink + nfnetlink
headers setup.
5) Remove documentation on several statified functions.
6) Remove printk on netns creation for the FTP IPVS tracker,
from Florian Westphal.
7) Remove unnecessary nf_tables_destroy_list_lock spinlock
initialization, from Yang Yingliang.
7) Remove a duplicated forward declaration in ipset,

have been removed too so no calls to nfnl functions are possible either.

Currently, we can specify ifindex on link creation. This change allows
to specify ifindex when a device is moved to another network namespace.
Even now, a device ifindex can be changed if there is another device
with the same ifindex in the target namespace. So this change doesn't
introduce completely new behavior, it adds more control to the process.
CRIU users want to restore containers with pre-created network devices.
A user will provide network devices and instructions where they have to
be restored, then CRIU will restore network namespaces and move devices
into them. The problem is that devices have to be restored with the same
indexes that they have before C/R.

struct ip6_sf_socklist and ipv6_mc_socklist are per-socket MLD data.
These data are protected by rtnl lock, socket lock, and RCU.
So, when these are used, it verifies whether rtnl lock is acquired or not.
ip6_mc_msfget() is called by do_ipv6_getsockopt().
But caller doesn't acquire rtnl lock.
So, when these data are used in the ip6_mc_msfget() lockdep warns about it.
But accessing these is actually safe because socket lock was acquired by
do_ipv6_getsockopt().
So, it changes lockdep annotation from rtnl lock to socket lock.
(rtnl_dereference -> sock_dereference)
Locking graph for mld data is like below:
When writing mld data:
do_ipv6_setsockopt()
rtnl_lock
lock_sock
(mld functions)
idev->mc_lock(if per-interface mld data is modified)
When reading mld data:
do_ipv6_getsockopt()
lock_sock
ip6_mc_msfget()

The MPTCP reset option allows to carry a mptcp-specific error code that
provides more information on the nature of a connection reset.
Reset option data received gets stored in the subflow context so it can
be sent to userspace via the 'subflow closed' netlink event.
When a subflow is closed, the desired error code that should be sent to
the peer is also placed in the subflow context structure.
If a reset is sent before subflow establishment could complete, e.g. on
HMAC failure during an MP_JOIN operation, the mptcp skb extension is
used to store the reset information.

Currently sockmap calls into each protocol to update the struct
proto and replace it. This certainly won't work when the protocol
is implemented as a module, for example, AF_UNIX.
Introduce a new ops sk->sk_prot->psock_update_sk_prot(), so each
protocol can implement its own way to replace the struct proto.
This also helps get rid of symbol dependencies on CONFIG_INET.
