Dear all,

below you find a link to the latest release of sctplib. This version
may become version 1.0.0 soon, if noone comes up with any more bug reports
on this list.

Please, test this release, even if you are using an older release (such as
pre19), you REALLY should upgrade. This version here has been tested quite
extensively at the 6th SCTP interop in Newark, Delaware.
Fixed issues:
- - flow/congestion control fixes as described in the implementor's
guide (e.g. fast recovery, no more cwnd timers, etc.)
- - IPv6 support fixed again (did not work properly in some cases)
- - handling of unknown parameters in INIT/INIT ACK fixed
- - Acknowledgement of data chunks with cum-TSN-Acked in SHUTDOWN-chunk now
works correctly (even when no SACK are sent along)
- - array of local addresse was not initialized correctly (now it is :-)
- - filtering of addresses works better now (mostly an IPv6 issue)
- - cleaned up a forgotten timer

Known/open issues, that may be removed later (probably not in the 1.0.0
branch, though):
- - RWND handling and updating is not optimal; functions for handling the
Silly Window Syndrome (SWS) need to be put in place; i.e. performance
for small window sizes is very, very bad :-(
- - the implementation does not do ICMP MTU path discovery, and adapt
fragmentation of new data chunks properly. Send patches ! :-)
- - We do not have a proper partial delivery API (which is ugly, when peer
sends very large, i.e. messages larger than our RWND)
Anyway, a message should be a message, and not a file.... :-)
- - We do not support ECN. Anyone know how ECN is supposed to work ?
Send patches ! :-)
- - ADDIP is not included. This will come when we officially release the
1.1.0 (i.e. experimental) branch.

BTW: here is the link (should be all on one line !):

Happy SCTPing,

Andreas
