Patch 3/7 and 4/7 are to implement receiver-side procedures for the Outgoing and Incoming SSN Reset Request Parameter described in rfc6525 section 5.2.2 and 5.2.3
Patch 1/7 and 2/7 are ahead of them to define some apis. Patch 5/7-7/7 are to add the process of reconf chunk event in rx path. Note that with this patchset, asoc->reconf_enable has no chance yet to be set, until the patch "sctp: add get and set sockopt for reconf_enable" is applied in the future. As we can not just enable it when sctp is not capable of processing reconf chunk yet. v1->v2: - re-split the patchset and make sure it has no dead codes for review. - rename the titles of the commits and improve some changelogs. - drop __packed from some structures in patch 1/7. - fix some kbuild warnings in patch 3/7 by initializing str_p = NULL. - sctp_chunk_lookup_strreset_param changes to return sctp_paramhdr_t * and uses sctp_strreset_tsnreq to access request_seq in patch 3/7. - use __u<size> in uapi sctp.h in patch 1/7. - do str_list endian conversion when generating stream_reset_event in patch 2/7. - remove str_list endian conversion, pass resp_seq param with network endian to lookup_strreset_param in 3/7. - move str_list endian conversion out of sctp_make_strreset_req, so that sctp_make_strreset_req can be used more conveniently to process inreq in patch 4/7. - remove sctp_merge_reconf_chunk and not support response with multiparam in patch 6/7.
