Ok, here it is, we finally add SCTP to current. Note that this work is not just mine, but it is also the works of Peter Lei and Michael Tuexen. They both are my two key other developers working on the project.. and they need ata-boy's too: **** peterlei@cisco.com tuexen@fh-muenster.de **** I did do a make sysent which updated the syscall's and sysproto.. I hope that is correct... without it you don't build since we have new syscalls for SCTP :-0 So go out and look at the NOTES, add option SCTP (make sure inet and inet6 are present too) and play with SCTP. I will see about comitting some test tools I have after I figure out where I should place them. I also have a lib (libsctp.a) that adds some of the missing socketapi functions that I need to put into lib's.. I will talk to George about this :-) There may still be some 64 bit issues in here, none of us have a 64 bit processor to test with yet.. Michael may have a MAC but thats another beast too.. If you have a mac and want to use SCTP contact Michael he maintains a web site with a loadable module with this code :-) Reviewed by: gnn Approved by: gnn

1) Adds the rest of the VIMAGE change macros 2) Adds some __UserSpace__ on some of the common defines that the user space code needs 3) Fixes a bug when we send up data to a user that failed. We need to a) trim off the data chunk headers, if present, and b) make sure the frag bit is communicated properly for the msgs coming off the stream queues... i.e. we see if some of the msg has been taken. Obtained from: jeli contributed the VIMAGE changes on this pass Thanks Julain!

- Static analyisis fixes for cisco's commit (this is equivilant to the coverity tool.. may even be the same one.. not sure). - A bug in the way sctp_abort() and friends were setting the IP_CLOSE flag.. and NOT passing the last argument as a (,1)... so that things would get freed..

- Adds support for the multi-asconf (From Kozuka-san) - Adds some prepwork (Not all yet) for vimage in particular support the delete the sctppcbinfo.xx structs. There is still a leak in here if it were to be called plus we stil need the regrouping (From Me and Michael Tuexen) - Adds support for UDP tunneling. For BSD there is no socket yet setup so its disabled, but major argument changes are in here to emcompass the passing of the port number (zero when you don't have a udp tunnel, the default for BSD). Will add some hooks in UDP here shortly (discussed with Robert) that will allow easy tunneling. (Mainly from Peter Lei and Michael Tuexen with some BSD work from me :-D) - Some ease for windows, evidently leave is reserved by their compile move label leave: -> out: MFC after: 1 week

- Consolidate the code that free's chunks to actually also call the sctp_free_remote_address() function. - Assure that when we allocate a chunk the whoTo is NULL, also when we free it and place it into the cache we NULL it (that way the consolidation code will always work). - Fix a small race, when a empty data holder is left on the stream out queue, and both sides do a shutdown, the empty data holder would prevent us from sending a SHUTDOWN-ACK and at the same time we never would cleanup the empty holder (since nothing was ever in queue). We now add a utility function that a) cleans up empty holders and b) properly determines if there are still pending data chunks on the stream out wheel. Approved by: re@freebsd.org (Ken Smith)
