| H A D | tcp_reass.c | diff 103505 Tue Sep 17 22:21:37 MDT 2002 dillon Guido reported an interesting bug where an FTP connection between a Windows 2000 box and a FreeBSD box could stall. The problem turned out to be a timestamp reply bug in the W2K TCP stack. FreeBSD sends a timestamp with the SYN, W2K returns a timestamp of 0 in the SYN+ACK causing FreeBSD to calculate an insane SRTT and RTT, resulting in a maximal retransmit timeout (60 seconds). If there is any packet loss on the connection for the first six or so packets the retransmit case may be hit (the window will still be too small for fast-retransmit), causing a 60+ second pause. The W2K box gives up and closes the connection. This commit works around the W2K bug. 15:04:59.374588 FREEBSD.20 > W2K.1036: S 1420807004:1420807004(0) win 65535 <mss 1460,nop,wscale 2,nop,nop,timestamp 188297344 0> (DF) [tos 0x8] 15:04:59.377558 W2K.1036 > FREEBSD.20: S 4134611565:4134611565(0) ack 1420807005 win 17520 <mss 1460,nop,wscale 0,nop,nop,timestamp 0 0> (DF) Bug reported by: Guido van Rooij <guido@gvr.org> |
