Now sctp only delays the authentication for the normal cookie-echo chunk by setting chunk->auth_chunk in sctp_endpoint_bh_rcv(). But for the duplicated one with auth, in sctp_assoc_bh_rcv(), it does authentication first based on the old asoc, which will definitely fail due to the different auth info in the old asoc. The duplicated cookie-echo chunk will create a new asoc with the auth info from this chunk, and the authentication should also be done with the new asoc's auth info for all of the collision 'A', 'B' and 'D'. Otherwise, the duplicated cookie-echo chunk with auth will never pass the authentication and create the new connection. This issue exists since very beginning, and this fix is to make sctp_assoc_bh_rcv() follow the way sctp_endpoint_bh_rcv() does for the normal cookie-echo chunk to delay the authentication. While at it, remove the unused params from sctp_sf_authenticate() and define sctp_auth_chunk_verify() used for all the places that do the delayed authentication. v1->v2: fix the typo in changelog as Marcelo noticed.
