[MPTCP] [PATCH 0/3] mptcp: fix for ipv6-related oops

[Paolo Abeni <pabeni at redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 986 bytes --]

We need to allocate a larger struct sock for mptcp v6 master sockets,
otherwise inet6_sk() will access mptcp related data instead of
struct ipv6_pinfo.

This should fix the crash reported by Matt.

The protocol.c code changes are split in 2 patches to simplify the
squashing.
(yep, I know we somewhat agreed to big giant rebase, but this specific
should be trivial).

Additionally adds some fixlet for the ipv6 tests

v1 -> v2:
 - address Matt feedback on patches 1 && 2
 - add missing mptcp_v6 proto registration (I don't know why the previous
   iteration of these patches did not explode without that!!! :(((

Paolo Abeni (3):
  selftests: fixup for IPv6 tests
  mptcp: use ipv6-specific proto struct
  mptcp/ipv6: mptcp_v6_prot needs costom destroy.
