Hello
 
I'm receiving the RESTART notification from the SCTP stack. The scenario is this:
 
0) Association is established between A and B
1) Side B calls sctp_shutdown, but the call is manually deferred right after the function returns (the association stated changes to SHUTDOWNSENT)
2) Side A crashes ungracefully
3) Side A restarts and initiates the association to B using the same source and destination ports
4) Side B continues and the ULP receives the RESTART notification
 
 
I was wondering if this is the correct behavior. The RFC states (in 5.2.4) that the restart rules apply in any state, however in this case it does not make much sense.
 
Any suggestions?
 
thanks
oleg
