Date: Fri, 11 Jul 2014 13:40:26 +0300 From: Alexey Dobriyan <adobriyan@...il.com> To: Florian Westphal <fw@...len.de> Cc: netdev <netdev@...r.kernel.org> Subject: FYI: Router causes TCP retransmits for windows hosts after "ip_forward: fix inverted local_df test" https://bugzilla.kernel.org/show_bug.cgi?id=79891 Theodor Milkov 2014-07-10 13:20:06 UTC Created attachment 142651 [details] TCP retransmissions from a windows host After upgrading a router to Linux 3.2.60 most windows machines behind it started experiencing connection stalls. Downgrade to 3.2.59 resolved the problem. Using git bisect I pinpointed it to "59d9f389df3cdf72833d5ee17c3fe959b6bdc792 is the first bad commit", which entered the kernel from here http://marc.info/?l=linux-netdev&m=139949081418806&w=2 No connection problems for Linux hosts at all – only windows. Please, find attached tcpdump packet capture demonstrating the bad behaviour. [reply] [−] Comment 1 Theodor Milkov 2014-07-11 05:44:45 UTC I wonder if this is the same bug discussed in the Debian bug tracker: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754294 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
