[SRU K,HWE-5.17,J,OEM-5.14,F,B 0/3] CVE-2022-3567 // CVE-2022-3566

[Thadeu Lima de Souza Cascardo]

[Impact]
Under some race conditions, a different sk_prot (specially when an IPv6
socket is downgraded to IPv4) or a icsk_af_ops may be read.

[Backport]
An extra pre-req also fixing such data races was applied. Some context
has changed, new functions were introduced, other functions have been moved
and some hooks were not called. That lead to this final backport.

[Potential regression]
We may see failures and crashes on TCP and IPv6 workloads.

Eric Dumazet (1):
  ipv6: annotate some data-races around sk->sk_prot

Kuniyuki Iwashima (2):
  ipv6: Fix data races around sk->sk_prot.
  tcp: Fix data races around icsk->icsk_af_ops.
