[SRU][F][PATCH 0/1] fix tcp NULL ptr deref

[Bethany Jamison]

Buglink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077657

This patch fixes bug LP#2077657 where a system crash is reported due
to a NULL pointer dereference in TCP. This is because of issues
accurately tracking packets in the write or retransmit queues. This
patch checks that the skb is non-null before trying to read the 
timestamp.
