Subject: [PATCH net 0/2] tcp: add tcp_v4_fill_cb()/tcp_v4_restore_cb()

James Morris reported kernel stack corruption bug that
we tracked back to commit 971f10eca186 ("tcp: better TCP_SKB_CB
layout to reduce cache line misses")

First patch needs to be backported to kernels >= 3.18,
while second patch needs to be backported to kernels >= 4.9, since
this was the time when inet_exact_dif_match appeared.

David Ahern (1):
  tcp: use IPCB instead of TCP_SKB_CB in inet_exact_dif_match()

Eric Dumazet (1):
  tcp: add tcp_v4_fill_cb()/tcp_v4_restore_cb()
