Subject: [PATCH v1 net 0/2] tcp: Fix bhash2 and TIME_WAIT regression.

We forgot to add twsk to bhash2.  Therefore TIME_WAIT sockets cannot
prevent bind() to the same local address and port.


Changes:
  v1:
    * Patch 1:
      * Add tw_bind2_node in inet_timewait_sock instead of
        moving sk_bind2_node from struct sock to struct
	sock_common.

  RFC: https://lore.kernel.org/netdev/20221221151258.25748-1-kuniyu@amazon.com/


Kuniyuki Iwashima (2):
  tcp: Add TIME_WAIT sockets in bhash2.
  tcp: Add selftest for bind() and TIME_WAIT.
