Subject: [PATCH v3 net 0/2] net: Fix error/warning by -fstrict-flex-arrays=3.

df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") started applying
strict rules for standard string functions (strlen(), memcpy(), etc.) if
CONFIG_FORTIFY_SOURCE=y.

This series fixes two false positives caught by syzkaller.


Changes:
  v3:
    * Drop Reviewed-by
    * Patch 1: Use strnlen()
    * Patch 2: Add a new flex array member

  v2: https://lore.kernel.org/netdev/20230720004410.87588-1-kuniyu@amazon.com/
    * Patch 2: Fix offset calc.

  v1: https://lore.kernel.org/netdev/20230719185322.44255-1-kuniyu@amazon.com/


Kuniyuki Iwashima (2):
  af_unix: Fix fortify_panic() in unix_bind_bsd().
  af_packet: Fix warning of fortified memcpy() in packet_getname().
