IPv6/TCP ROHC Aborted

Asked by saadan ansari

Hi Didier,

Playing around with ROHC IPv6/TCP I experienced several times the following error:

[c_tcp.c:2477 c_sack_pure_lsb( )] sack_field = FFFFFFFEh ( 9EB4974Bh - 9EB4974Dh ) Aborted ) core dumped.

Any remedy?

Thanx
Saadan

Saadan,

FWX answered you on the mailing list [1] :

| Hello Saadan,
|
| The bug happened when compressing a TCP SACK option.
|
| To help us to resolve the problem, can you send us a capture file
| (.pcap file) of the connection ?
|
| Thanks,

Hi Didier,

Please find enclosed the pcap of the connection.
You can identify the break at packet No. 631, which happens after reception and decompression of packet No. 630.

Thanx
Saadan
