Hi,
I was running application on linux [server-client type].
It comunicate through sctp protocol.
And while doing test, I observe that server side is sending SHUTDOWN
requext to clinet but client side fail to response back with
SHUTDOWN_ACK.
So I tried to enable Kernel SCTP logs and found that SHUTDOWN_ACK is
not send out of stack. I am using debian os with old kernel 2.6.33.
Attached: sctp_log.txt
[In this log, I not able to see SCTP is doing sctp_outq_flush(..) call ]
I don't have log for below my trial:
I tried adding some printk in sctp_cmd_interpreter() as shown below:
if (asoc && SCTP_EVENT_T_CHUNK == event_type && chunk) {
printk("sctp : end_of_packet : %d, singleton :
%d",chunk->end_of_packet, chunk->singleton);
if (chunk->end_of_packet || chunk->singleton)
error = sctp_outq_uncork(&asoc->outqueue);
} else if (local_cork)
error = sctp_outq_uncork(&asoc->outqueue);
return error;
And found that it printed out as "sctp : end_of_packet : 0, singleton : 0"
Please let me know if you know this issue.
And already had been fix please share the patch.
Few more doubts:
In sctp_rcv,
I not seen we are updating chunk_end field. Do we need to update
it for recived packet ?
Thanks,
~Rohit
