Subject: [PATCH net-next 0/2] add more drop reasons in tcp receive path

From: Jason Xing <kernelxing@...cent.com>

When I was debugging the reason about why the skb should be dropped in
syn cookie mode, I found out that this NOT_SPECIFIED reason is too
general. Thus I decided to refine it.

Jason Xing (2):
  tcp: add more DROP REASONs in cookie check
  tcp: add more DROP REASONS in child process
