Subject: [PATCH net-next 0/3] sctp: add proper process for duplicated stream reconf requests

Now sctp stream reconf will process a request again even if it's seqno
is less than asoc->strreset_inseq. It may cause a replay attack.

This patchset is to avoid it by add proper process for all duplicated
stream reconf requests.

Xin Long (3):
  sctp: process duplicated strreset out and addstrm out requests
    correctly
  sctp: process duplicated strreset in and addstrm in requests correctly
  sctp: process duplicated strreset asoc request correctly
