Message-id: <4B5576F4.5020002@tvk.rwth-aachen.de> Date: Tue, 19 Jan 2010 10:10:12 +0100 From: Damian Lukowski <damian@....rwth-aachen.de> To: Denys Fedoryshchenko <denys@...p.net.lb> Cc: Ilpo Järvinen <ilpo.jarvinen@...sinki.fi>, netdev@...r.kernel.org Subject: Re: Crazy TCP bug (keepalive flood?) in 2.6.32? Hi, thank you for testing. So srtt and rttvar is zero in any of those cases. Ilpo, it is a bug in tcp_rtt_estimator then, I suppose? There is also a code comment in tcp_input.c, saying: > * NOTE: clamping at TCP_RTO_MIN is not required, current algo > * guarantees that rto is higher. So we either fix tcp_rtt_estimator or simply clamp at TCP_RTO_MIN? Damian > On Monday 11 January 2010 15:02:34 you wrote: >> On Sat, 26 Dec 2009, Denys Fedoryshchenko wrote: >>> Few more dumps.
