- Sysctl's move to seperate file - moved away from ifn/ifa access to sctp_ifa/sctp_ifn built and managed by the add-ip code. - cleaned up add-ip code to use the iterator - made iterator be a thread, which enables auto-asconf now. - rewrote and cleaned up source address selection (also made it use new structures). - Fixed a couple of memory leaks. - DACK now settable as to how many packets to delay as well as time. - connectx() to latest socket API, new associd arg. - Fixed issue with revoking and loosing potential to send when we inflate the flight size. We now inflate the cwnd too and deflate it later when the revoked chunk is sent or acked. - Got rid of some temp debug code - src addr selection moved to a common file (sctp_output.c) - Support for simple VRF's (we have support for multi-vfr via compile switch that is scrubbed from BSD but we won't need multi-vrf until we first get VRF :-D) - Rest of mib work for address information now done - Limit number of addresses in INIT/INIT-ACK to a #def (30).

This saves about 92 bytes from each struct by carefully converting to use the smaller version. - one-2-one model get(maxseg) would always get ep value, never the tcb's value. - The delayed ack time could be under a tick, this fixes so it bounds it to at least 1 tick for platforms whos tick is more than a ms. - Fragment interleave level set to wrong default value. - Fragment interleave could not set level 0. - Defered stream reset was broken due to a guard check and ntohl issue. - Found two lock order reversals and fixed. - Tighten up address checking, if the user gives an address the sa_len had better be set properly. - Get asoc by assoc-id would return a locked tcb when it was asked not to if the tcb was in the restart hash. - sysctl to dig down and get more association details Reviewed by: gnn

- fixed several places where we did not release INP locks. - 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.

We now fix this with having a mark on the net and the chunk so we can clear it out when the sack arrives forcing it to retran just like it was "new" this improves the handling of window probes, which were dropped by the receiver. - Tighten AUTH protocol error checks during INIT/INIT-ACK exchange

- More macros for OS compatabilty - PR-SCTP would ignore FWD-TSN's above a rwnd's worth of TSN's (1 byte msgs).. this left the peer hopelessly out of sync.. or an attacker. So now we abort the assoc. - New IFN hash, also rename hashes to match addr/ifn now that the vrf has multiple. - Do not enable SCTP_PCB_FLAGS_RECVDATAIOEVNT per default as defined in the Socket API ID. - Export MTU information via sysctl. - Vrf's need table id's. This is default for BSD, but may be other things later when BSD fully supports VRFs. - Additional stream reset bug (caught by cisco dev-test). - Additional validations for the address in sending a message (socket api). -------- and ----- - Fix association notifications not to give the active open side false notifications. - Fix so sendfile and SENDALL will work properly (missing flag to say socket sender is done). - Fix Bug that prevented COOKIES from being retransmitted. - Break out connectx into helper sub-models so that iox routines can reuse the helpers. - When an address is added during system init (non-dynamic mode) make sure that the "defer use" flag is not set. ** its compiling on XR now :-D ** Reviewed by: gnn

- Fixed 1-2-1 model to not worry about associd in sockopts - Fixed RTOinfo for bounding. - Fixed connect() to return ECONNREFUSED when an ABORT is received. - Added comments to direct Static Analysis not to look at some things it does not understand (comments are /* sa_ignore XXXXX */) - Bind when colliding was broken, missing not_found = 1 before checking to see if the port was in use caused endless bind loop. - Cookie life needs to be in milliseconds to conform to socket api. - Cookie life is not supposed to change if its 0, On the assoc level set we changed it to 0 opps. - Two more static analysis issues identified by the cisco tool. Null checks needed. - An issue for sendfile(). Need to validate the correct input argument. - When sending failed due to a no route to host, we leaked the mbuf chain failing to call m_freem(). - Fix #ifdef issue for getting hash block len when HAVE_SHA2 is NOT defined Reviewed by: gnn

- Sysctl's move to seperate file - moved away from ifn/ifa access to sctp_ifa/sctp_ifn built and managed by the add-ip code. - cleaned up add-ip code to use the iterator - made iterator be a thread, which enables auto-asconf now. - rewrote and cleaned up source address selection (also made it use new structures). - Fixed a couple of memory leaks. - DACK now settable as to how many packets to delay as well as time. - connectx() to latest socket API, new associd arg. - Fixed issue with revoking and loosing potential to send when we inflate the flight size. We now inflate the cwnd too and deflate it later when the revoked chunk is sent or acked. - Got rid of some temp debug code - src addr selection moved to a common file (sctp_output.c) - Support for simple VRF's (we have support for multi-vfr via compile switch that is scrubbed from BSD but we won't need multi-vrf until we first get VRF :-D) - Rest of mib work for address information now done - Limit number of addresses in INIT/INIT-ACK to a #def (30).

- fixed several places where we did not release INP locks. - 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.
