validate_ftsn is added as a member of sctp_stream_interleave, used to validate ssn/chunk type for fwdtsn or mid (message id)/chunk type for ifwdtsn, called in sctp_sf_eat_fwd_tsn, just as validate_data. If this check fails, an abort packet will be sent, as said in section 2.3.1 of RFC8260. As ifwdtsn and fwdtsn chunks have different length, it also defines ftsn_chunk_len for sctp_stream_interleave to describe the chunk size. Then it replaces all sizeof(struct sctp_fwdtsn_chunk) with sctp_ftsnchk_len. It also adds the process for ifwdtsn in rx path. As Marcelo pointed out, there's no need to add event table for ifwdtsn, but just share prsctp_chunk_event_table with fwdtsn's. It would drop fwdtsn chunk for ifwdtsn and drop ifwdtsn chunk for fwdtsn by calling validate_ftsn in sctp_sf_eat_fwd_tsn. After this patch, the ifwdtsn can be accepted. Note that this patch also removes the sctp.intl_enable check for idata chunks in sctp_chunk_event_lookup, as it will do this check in validate_data later.
