2008-09-23ipsec: Fix xfrm_state_walk raceHerbert Xu3-17/+34
As discovered by Timo Teräs, the currently xfrm_state_walk scheme is racy because if a second dump finishes before the first, we may free xfrm states that the first dump would walk over later. This patch fixes this by storing the dumps in a list in order to calculate the correct completion counter which cures this problem. I've expanded netlink_cb in order to accomodate the extra state related to this. It shouldn't be a big deal since netlink_cb is kmalloced for each dump and we're just increasing it by 4 or 8 bytes.

2008-09-21tcp: advertise MSS requested by userTom Quetchenbach2-3/+14
I'm trying to use the TCP_MAXSEG option to setsockopt() to set the MSS for both sides of a bidirectional connection. man tcp says: "If this option is set before connection establishment, it also changes the MSS value announced to the other end in the initial packet." However, the kernel only uses the MTU/route cache to set the advertised MSS. That means if I set the MSS to, say, 500 before calling connect(), I will send at most 500-byte packets, but I will still receive 1500-byte packets in reply. This is a bug, either in the kernel or the documentation. This patch (applies to latest net-2.6) reduces the advertised value to that requested by the user as long as setsockopt() is called before connect() or accept(). This seems like the behavior that one would expect as well as that which is documented. I've tried to make sure that things that depend on the advertised MSS are set correctly.

2008-09-21tcp: back retransmit_high when it over-estimatedIlpo Järvinen1-2/+10
If lost skb is sacked, we might have nothing to retransmit as high as the retransmit_high is pointing to, so place it lower to avoid unnecessary walking. This is mainly for the case where high L'ed skbs gets sacked. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-21tcp: don't clear lost_skb_hint when not necessaryIlpo Järvinen1-1/+13
Most importantly avoid doing it with cumulative ACK. However, since we have lost_cnt_hint in the picture as well needing adjustments, it's not as trivial as dealing with retransmit_skb_hint (and cannot be done in the all place we could trivially leave retransmit_skb_hint untouched). With the previous patch, this should mostly remove O(n^2) behavior while cumulative ACKs start flowing once rexmit after a lossy round-trip made it through.

2008-09-21tcp: don't clear retransmit_skb_hint when not necessaryIlpo Järvinen3-5/+14

2008-09-21tcp: remove retransmit_skb_hint clearing from failureIlpo Järvinen1-3/+1
This doesn't much sense here afaict, probably never has. Since fragmenting and collapsing deal the hints by themselves, there should be very little reason for the rexmit loop to do that. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-21tcp: reorganize retransmit code loopsIlpo Järvinen3-48/+33

2008-09-21tcp: No need to clear retransmit_skb_hint when SACKingIlpo Järvinen1-7/+0
Because lost counter no longer requires tuning, this is trivial to remove (the tuning wouldn't have been too hard either) because no "new" retransmittable skb appeared below retransmit_skb_hint when SACKing for sure.

2008-09-21tcp: Kill precaution that's very likely obsoleteIlpo Järvinen1-4/+0
I suspect it might have been related to the changed amount of lost skbs, which was counted by retransmit_cnt_hint that got changed. The place for this clearing was very illogical anyway, it should have been after the LOST-bit clearing loop to make any sense.

2008-09-21tcp: convert retransmit_cnt_hint to seqnoIlpo Järvinen4-33/+30
Main benefit in this is that we can then freely point the retransmit_skb_hint to anywhere we want to because there's no longer need to know what would be the count changes involve, and since this is really used only as a terminator, unnecessary work is one time walk at most, and if some retransmissions are necessary after that point later on, the walk is not full waste of time anyway. Since retransmit_high must be kept valid, all lost markers must ensure that. Now I also have learned how those "holes" in the rexmittable skbs can appear, mtu probe does them. So I removed the misleading comment as well. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
