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

- most all includes (#include <>) migrate to the sctp_os_bsd.h file - Finally all splxx() are removed - Count error fixed in mapping array which might cause a wrong cumack generation. - Invariants around panic for case D + printf when no invariants. - one-to-one model race condition fixed by using a pre-formed connection and then completing the work so accept won't happen on a non-formed association. - Some additional paranoia checks in sctp_output. - Locks that were missing in the accept code.

-Fixes first of all the getcred on IPv6 and V4. The copy's were incorrect and so was the locking. -A bug was also found that would create a race and panic when an abort arrived on a socket being read from. -Also fix the reader to get MSG_TRUNC when a partial delivery is aborted. -Also addresses a couple of coverity caught error path memory leaks and a couple of other valid complaints Approved by: gnn

a) macro-ization of all mbuf and random number access plus timers.

- Macroizes the V6ONLY flag check. - Added a short time wait (not used yet) constant - Corrected the type of the crc32c table (it was unsigned long and really is a uint32_t - Got rid of the user of MHeaders until they are truely needed by lower layers. - Fixed an initialization problem in the readq structure (ordering was off). - Found yet another collision bug when the random number generator returns two numbers on one side (during a collision) that are the same. Also added some tracking of cookies that will go away when we know that we have the last collision bug gone. - Fixed an init bug for book_size_scale, that was causing Early FR code to run when it should not. - Fixed a flight size tracking bug that was associated with Early FR but due to above bug also effected all FR's - Fixed it so Max Burst also will apply to Fast Retransmit. - Fixed a bug in the temporary logging code that allowed a static log array overflow - hashinit_flags is now used. - Two last mcopym's were converted to the macro sctp_m_copym that has always been used by all other places - macro sctp_m_copym was converted to upper case. - We now validate sinfo_flags on input (we did not before). - Fixed a bug that prevented a user from sending data and immediately shuting down with one send operation. - Moved to use hashdestroy instead of free() in our macros. - Fixed an init problem in our timed_wait vtag where we did not fully initialize our time-wait blocks. - Timer stops were re-positioned. - A pcb cleanup method was added, however this probably will not be used in BSD.. unless we make module loadable protocols - I think this fixes the mysterious timer bug.. it was a ordering of locks problem in the way we did timers. It now conforms to the timeout(9) manual (except for the _drain part, we had to do this a different way due to locks). - Fixed error return code so we get either CONNREUSED or CONNRESET depending on where one is in progression - Purged an unused clone macro. - Fixed a read erro code issue where we were NOT getting the proper error when the connection was reset. - Purged an unused clone macro. - Fixed a read erro code issue where we were NOT getting the proper error when the connection was reset.

1) Fixes on a number of different collision case LOR's. 2) Fix all "magic numbers" to be constants. 3) A collision case that would generate two associations to the same peer due to a missing lock is fixed. 4) Added tracking of where timers are stopped. Approved by: gnn

a) macro-ization of all mbuf and random number access plus timers. This makes the code more portable and able to change out the mbuf or timer system used more easily ;-) b) removal of all use of pkt-hdr's until only the places we need them (before ip_output routines). c) remove a bunch of code not needed due to <b> aka worrying about pkthdr's :-) d) There was one last reorder problem it looks where if a restart occur's and we release and relock (at the point where we setup our alias vtag) we would end up possibly getting the wrong TSN in place. The code that fixed the TSN's just needed to be shifted around BEFORE the release of the lock.. also code that set the state (since this also could contribute). Approved by: gnn

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..

1) Fixes on a number of different collision case LOR's. 2) Fix all "magic numbers" to be constants. 3) A collision case that would generate two associations to the same peer due to a missing lock is fixed. 4) Added tracking of where timers are stopped. Approved by: gnn

- Macroizes the V6ONLY flag check. - Added a short time wait (not used yet) constant - Corrected the type of the crc32c table (it was unsigned long and really is a uint32_t - Got rid of the user of MHeaders until they are truely needed by lower layers. - Fixed an initialization problem in the readq structure (ordering was off). - Found yet another collision bug when the random number generator returns two numbers on one side (during a collision) that are the same. Also added some tracking of cookies that will go away when we know that we have the last collision bug gone. - Fixed an init bug for book_size_scale, that was causing Early FR code to run when it should not. - Fixed a flight size tracking bug that was associated with Early FR but due to above bug also effected all FR's - Fixed it so Max Burst also will apply to Fast Retransmit. - Fixed a bug in the temporary logging code that allowed a static log array overflow - hashinit_flags is now used. - Two last mcopym's were converted to the macro sctp_m_copym that has always been used by all other places - macro sctp_m_copym was converted to upper case. - We now validate sinfo_flags on input (we did not before). - Fixed a bug that prevented a user from sending data and immediately shuting down with one send operation. - Moved to use hashdestroy instead of free() in our macros. - Fixed an init problem in our timed_wait vtag where we did not fully initialize our time-wait blocks. - Timer stops were re-positioned. - A pcb cleanup method was added, however this probably will not be used in BSD.. unless we make module loadable protocols - I think this fixes the mysterious timer bug.. it was a ordering of locks problem in the way we did timers. It now conforms to the timeout(9) manual (except for the _drain part, we had to do this a different way due to locks). - Fixed error return code so we get either CONNREUSED or CONNRESET depending on where one is in progression - Purged an unused clone macro. - Fixed a read erro code issue where we were NOT getting the proper error when the connection was reset. - Purged an unused clone macro. - Fixed a read erro code issue where we were NOT getting the proper error when the connection was reset.

a) macro-ization of all mbuf and random number access plus timers. This makes the code more portable and able to change out the mbuf or timer system used more easily ;-) b) removal of all use of pkt-hdr's until only the places we need them (before ip_output routines). c) remove a bunch of code not needed due to <b> aka worrying about pkthdr's :-) d) There was one last reorder problem it looks where if a restart occur's and we release and relock (at the point where we setup our alias vtag) we would end up possibly getting the wrong TSN in place. The code that fixed the TSN's just needed to be shifted around BEFORE the release of the lock.. also code that set the state (since this also could contribute). Approved by: gnn

/* assoc gone no un-lock */
1) Fixes on a number of different collision case LOR's. 2) Fix all "magic numbers" to be constants. 3) A collision case that would generate two associations to the same peer due to a missing lock is fixed. 4) Added tracking of where timers are stopped. Approved by: gnn

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.

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..

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..

- most all includes (#include <>) migrate to the sctp_os_bsd.h file - Finally all splxx() are removed - Count error fixed in mapping array which might cause a wrong cumack generation. - Invariants around panic for case D + printf when no invariants. - one-to-one model race condition fixed by using a pre-formed connection and then completing the work so accept won't happen on a non-formed association. - Some additional paranoia checks in sctp_output. - Locks that were missing in the accept code.

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
