- fixed a refcount bug in the new ifa structures. - use vrf's from default stcb or inp whenever possible. - Address limits raised to account for a full IP fragmented packet (1000 addresses). - flight size correcting updated to include one message only and to handle case where the peer does not cumack the next segment aka lists 1/1 in sack blocks.. - Various bad init/init-ack handling could cause a panic since we tried to unlock the destroyed mutex. Fixes so we properly exit when we need to destroy an assoc. (Found by Cisco DevTest team :D) - name rename in src-addr-selection from pass to sifa. - route structure typedef'd to allow different platforms and updated into sctp_os_bsd file. - Max retransmissions a chunk can be made added.
