[IPV6]: Audit all ip6_dst_lookup/ip6_dst_store calls

2006-08-02T20:38:14Z

The current users of ip6_dst_lookup can be divided into two classes: 1) The caller holds no locks and is in user-context (UDP). 2) The caller does not want to lookup the dst cache at all. The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't. This patch adds __ip6_dst_store for those (everyone except UDP/datagram) that don't need an extra lock. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[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.
