Subject: [PATCH v2 net 0/6] tcp: Fix bind() regression for v4-mapped-v6 address

Since bhash2 was introduced, bind() is broken in two cases related
to v4-mapped-v6 address.

This series fixes the regression and adds test to cover the cases.


Changes:
  v2:
    * Added patch 1 to factorise duplicated comparison (Eric Dumazet)

  v1: https://lore.kernel.org/netdev/20230911165106.39384-1-kuniyu@amazon.com/


Kuniyuki Iwashima (6):
  tcp: Factorise sk_family-independent comparison in
    inet_bind2_bucket_match(_addr_any).
  tcp: Fix bind() regression for v4-mapped-v6 wildcard address.
  tcp: Fix bind() regression for v4-mapped-v6 non-wildcard address.
  selftest: tcp: Fix address length in bind_wildcard.c.
  selftest: tcp: Move expected_errno into each test case in
    bind_wildcard.c.
  selftest: tcp: Add v4-mapped-v6 cases in bind_wildcard.c.
