[PATCH v2 net-next 0/2] add more drop reasons in tcp receive path

[Jason Xing <kerneljasonxing@gmail.com>]

From: Jason Xing <kernelxing@tencent.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.

v2:

1. change the title of 2/2 patch.
2. fix some warnings checkpatch tool showed before.
3. use return value instead of adding more parameters suggested by Eric.

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