Subject: [PATCH v2 net 0/2] ipv4: less uses of shared IP generator

From: Eric Dumazet <edumazet@...gle.com>

We keep receiving research reports based on linux IPID generation.

Before breaking part of the Internet by switching to pure
random generator, this series reduces the need for the
shared IP generator for TCP sockets.

v2: fix sparse warning in the first patch.

Eric Dumazet (2):
  ipv4: tcp: send zero IPID in SYNACK messages
  ipv4: avoid using shared IP generator for connected sockets
