dccp/tcp: Call security_inet_conn_request() after setting IPv6 addresses.

dccp/tcp: Call security_inet_conn_request() after setting IPv6 addresses.

[ Upstream commit 23be1e0e2a83a8543214d2599a31d9a2185a796b ]

Initially, commit 4237c75c0a35 ("[MLSXFRM]: Auto-labeling of child
sockets") introduced security_inet_conn_request() in some functions
where reqsk is allocated. The hook is added just after the allocation,
so reqsk's IPv6 remote address was not initialised then.

However, SELinux/Smack started to read it in netlbl_req_setattr()
after commit e1adea927080 ("calipso: Allow request sockets to be
relabelled by the lsm.").

Commit 284904aa7946 ("lsm: Relocate the IPv4 security_inet_conn_request()
hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was
not supported at that time. Finally, the same issue was introduced again
in IPv6.

Let's apply the same fix on DCCPv6 and TCPv6.

Fixes: e1adea927080 ("calipso: Allow request sockets to be relabelled by the lsm.")

====================
sysctl: Fix data-races around ipv4_net_table (Round 3).

This series fixes data-races around 21 knobs after
igmp_link_local_mcast_reports in ipv4_net_table.

These 4 knobs are skipped because they are safe.

- tcp_congestion_control: Safe with RCU and xchg().
- tcp_available_congestion_control: Read only.
- tcp_allowed_congestion_control: Safe with RCU and spinlock().
- tcp_fastopen_key: Safe with RCU and xchg()

So, round 4 will start with fib_multipath_use_neigh.
