From c7caf8d3ed7a6617aa0a3083815c439bd952c45c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=E4rvinen?= Date: Sat, 10 Nov 2007 21:22:18 -0800 Subject: [PATCH] [TCP]: Fix reord detection due to snd_una covered holes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fixes subtle bug like the one with fastpath_cnt_hint happening due to the way the GSO and hints interact. Because hints are not reset when just a GSOed skb is partially ACKed, there's no guarantee that the relevant part of the write queue is going to be processed in sacktag at all (skbs below snd_una) because fastpath hint can fast forward the entrypoint. This was also on the way of future reductions in sacktag's skb processing. Also future cleanups in sacktag can be made after this (in 2.6.25). This may make reordering update in tcp_try_undo_partial redundant but I'm not too sure so I left it there. Signed-off-by: Ilpo Järvinen Signed-off-by: David S.
