Increase the max_burst threshold from 3 to tp->reordering.

2008-05-01T21:49:01Z

[ Upstream commit: dd9e0dda66ba38a2ddd1405ac279894260dc5c36 ] This change is necessary to allow cwnd to grow during persistent reordering. Cwnd moderation is applied when in the disorder state and an ack that fills the hole comes in. If the hole was greater than 3 packets, but less than tp->reordering, cwnd will shrink when it should not have. Signed-off-by: John Heffner Signed-off-by: David S.

[TCP] MTUprobe: fix potential sk_send_head corruption

2007-11-20T07:24:09Z

When the abstraction functions got added, conversion here was made incorrectly. As a result, the skb may end up pointing to skb which got included to the probe skb and then was freed. For it to trigger, however, skb_transmit must fail sending as well. Signed-off-by: Ilpo J�rvinen Signed-off-by: David S. Miller

[TCP]: Remove unneeded implicit type cast when calling tcp_minshall_update()

2007-10-24T04:27:55Z

The tcp_minshall_update() function is called in exactly one place, and is passed an unsigned integer for the mss_len argument. Make the sign of the argument match the sign of the passed variable in order to eliminate an unneeded implicit type cast and a mixed sign comparison in tcp_minshall_update().

[TCP]: Avoid clearing sacktag hint in trivial situations

2007-10-10T23:52:12Z

There's no reason to clear the sacktag skb hint when small part of the rexmit queue changes. Account changes (if any) instead when fragmenting/collapsing. RTO/FRTO do not touch SACKED_ACKED bits so no need to discard SACK tag hint at all. Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller

[TCP]: Move sack_ok access to obviously named funcs & cleanup

2007-10-10T23:48:00Z

Previously code had IsReno/IsFack defined as macros that were local to tcp_input.c though sack_ok field has user elsewhere too for the same purpose. This changes them to static inlines as preferred according the current coding style and unifies the access to sack_ok across multiple files. Magic bitops of sack_ok for FACK and DSACK are also abstracted to functions with appropriate names. Note: - One sack_ok = 1 remains but that's self explanary, i.e., it enables sack - Couple of !IsReno cases are changed to tcp_is_sack - There were no users for IsDSack => I dropped it Signed-off-by: Ilpo Järvinen Signed-off-by: David S.

[TCP]: Don't panic if S+L skb is detected

2007-10-10T23:47:59Z

BUG_ON is an overkill. In fact, I was mislead by BUG_TRAP severity (equals to WARN_ON) which is much lower than BUG_ON's (that panics). Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller
