[DCCP]: Fix default sequence window size

2006-07-24T19:44:21Z

When using the default sequence window size (100) I got the following in my logs: Jun 22 14:24:09 localhost kernel: [ 1492.114775] DCCP: Step 6 failed for DATA packet, (LSWL(6279674225) <= P.seqno(6279674749) <= S.SWH(6279674324)) and (P.ackno doesn't exist or LAWL(18798206530) <= P.ackno(1125899906842620) <= S.AWH(18798206548), sending SYNC... Jun 22 14:24:09 localhost kernel: [ 1492.115147] DCCP: Step 6 failed for DATA packet, (LSWL(6279674225) <= P.seqno(6279674750) <= S.SWH(6279674324)) and (P.ackno doesn't exist or LAWL(18798206530) <= P.ackno(1125899906842620) <= S.AWH(18798206549), sending SYNC... I went to alter the default sysctl and it didn't take for new sockets. Below patch fixes this. I think the default is too low but it is what the DCCP spec specifies. As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec to 3.5. This is still far too slow but it is a step in the right direction. Compile tested only for IPv6 but not particularly complex change. Signed off by: Ian McDonald Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[DCCP]: Use sk->sk_prot->max_header consistently for non-data packets

2006-03-21T06:31:09Z

Using this also provides opportunities for introducing inet_csk_alloc_skb that would call alloc_skb, account it to the sock and skb_reserve(max_header), but I'll leave this for later, for now using sk_prot->max_header consistently is enough.

[DCCP] ipv6: Add missing ipv6 control socket

2006-03-21T06:00:37Z

I guess I forgot to add it, nah, now it just works: 18:04:33.274066 IP6 ::1.1476 > ::1.5001: request (service=0) 18:04:33.334482 IP6 ::1.5001 > ::1.1476: reset (code=bad_service_code) Ditched IP_DCCP_UNLOAD_HACK, as now we would have to do it for both IPv6 and IPv4, so I'll come up with another way for freeing the control sockets in upcoming changesets.
