From d02596e32925edaeccee0af8eb6c229b5615de42 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ilpo=20J=C3=A4rvinen?= Date: Sat, 7 Jul 2007 13:39:02 +0300 Subject: [PATCH] [TCP]: Keep state in Disorder also if only lost_out > 0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This happens rather infrequently and is only possible during FRTO. We must not allow TCP to slip to Open state because tcp_fastretrans_alert might then not be called on it's time when FRTO has exited. This become a problem when left_out got removed and was replaced by just sacked_out. Signed-off-by: Ilpo Järvinen Signed-off-by: David S.
