[4.14,0/5] inet6: Backport complete patchset for inet6_destroy_sock() call modification

Message

4.14 LTS has backported commit ca43ccf41224 ("dccp/tcp: Avoid negative
sk_forward_alloc by ipv6_pinfo.pktoptions.") and commit 62ec33b44e0f ("net:
Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues()."),
but these are incomplete. There are some patches that have not been
backported including key pre-patches commit d38afeec26ed ("tcp/udp:
Call inet6_destroy_sock() in IPv6 sk->sk_destruct().") and commit
b5fc29233d28 ("inet6: Remove inet6_destroy_sock() in
sk->sk_prot->destroy()."). Without them, there are some memory leak bugs.

Backport complete patchset for inet6_destroy_sock() call modification.

Kuniyuki Iwashima (5):
  udp: Call inet6_destroy_sock() in setsockopt(IPV6_ADDRFORM).
  tcp/udp: Call inet6_destroy_sock() in IPv6 sk->sk_destruct().
  inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy().
  dccp: Call inet6_destroy_sock() via sk->sk_destruct().
  sctp: Call inet6_destroy_sock() via sk->sk_destruct().
