Handling multiple path SCTP_ADDR_CONFIRMED primitive under event SCTP_PEER_ADDR_CHANGE?

+1 vote

When performing the following test on SCTP multi-homed association, I am seeing the SCTP_ADDR_CONFIRMED primitive coming back When bring back the last path up.

Could I handle the CONFIRMED primitive like the AVAILABLE primitive? Are there scenario that The confirmed is different from the AVAILABLE?

Event that I see the AVAILABLE and CONFIRMED generated

Path2 down (assoc down) - commLost
Path1 up - commUp and then SCTP_ADDR_UNREACHABLE on path2
Path2 up - SCTP_ADDR_CONFIRMED on 1 side of the connection and SCTP_ADDR_AVAILABLE on the other side of the connection

I'd like to add SCTP_SENDALL support to the kernel and lksctp-tools to port a FreeBSD project to Linux. Does anyone have pointers on where to get started or who to talk to about this? Is there any reason it's not already implemented besides just no one doing the work yet?

I'm adding experimental support for UDP encapsulation of SCTP packets. I got most of if working well. However, I noticed a NULL pointer dereference in sctp_packet_transmit as I assumed that packet->transport->asoc weren't NULL so I tried to access tunneling information that I store in packet->transport->asoc->ep->base.

In what circumstances is assoc NULL in sctp_packet_transmit?
