I removed parts of 2.5.43-bk1 and that solved my problem, see attached mail below. When I did this (2 weeks ago) I removed all changes that touched net/* and associated includes. I was not able to pinpoint the exact change that causes the problem, the changes there are a bit to much for my knowledge of the kernel, sorry. /B. ================================================================================= Date: Fri, 18 Oct 2002 12:47:17 +0200 From: Sebastian Benoit <benoit-lists@fb12.de> To: netdev@oss.sgi.com Subject: network connection gets stuck with 2.5.43-bk1/mm2 Message-ID: <20021018124717.A21622@turing.fb12.de> Hi, i posted the message below to linux-mm yesterday, Andrew Morton told me that it might be one of the changes in networking in -bk1. removing these changes solved the problem: include/linux/ip.h | 16=20 include/linux/tcp.h | 2=20 include/linux/udp.h | 31 - include/net/dst.h | 56 -- include/net/ip.h | 16=20 include/net/sock.h | 2=20 include/net/tcp.h | 2=20 include/net/udp.h | 2=20 net/core/dst.c | 25 - net/ipv4/af_inet.c | 17=20 net/ipv4/icmp.c | 4=20 net/ipv4/ip_output.c | 880 +++++++----------------------------------= ----- net/ipv4/ip_proc.c | 74 --- net/ipv4/ip_sockglue.c | 4=20 net/ipv4/raw.c | 7=20 net/ipv4/tcp.c | 49 -- net/ipv4/tcp_ipv4.c | 6=20 net/ipv4/tcp_minisocks.c | 10=20 net/ipv4/udp.c | 296 --------------- net/ipv6/tcp_ipv6.c | 5=20 net/netsyms.c | 1=20 (this is the diffstat of the reverse patch) Is this fixed already? /B. ----------------- quote ----------------- Hi,=20 funny problem w. 2.5.43-mm2: i'm running 2.5.43-mm2 on my workstation. Normal workload, X-windows, a few xterms, editor, mozilla, etc. (host A) I have a NFS/SAMBA-mount (both show the problem) to host B. Host B runs 2.4.19rc5aa1. I can get a xterm, in which i have a ssh-connection to a third host C 'stuck' by simply cat'ing a large file from the NFS/SAMBA server to /dev/null. The xterm/ssh seems stuck, that is no key i press is received on the other end, but output of the program running on host C is updated in the xterm. I checked with tcpdump: the keypress does not generate a packet, my host only sends ACK's on that ssh connection to host C. The ssh-connection is not unstuck by stopping the data transfer from host B. I checked that plain 2.5.42 and 2.5.43-mm1 do not have this problem: here my input goes through to C. At least for small amounts of input, i did not test anything beyond typing a few hundret chars. recap: "mount /mnt/hostB" "ssh hostC" -> type random stuff in that connection at the same time do "cat /mnt/hostB/bigfile > /dev/null" ssh gets stuck. hardware: PIII/600, 3c905B on 10baseT half-duplex I'm sorry i cant do any further checks until Friday afternoon (MET). /B. --------------- quote ends --------------- -- Sebastian Benoit <benoit-lists@fb12.de> My mail is GnuPG signed -- Unsigned ones are bogus -- http://www.gnupg.org/ GnuPG 0x5BA22F00 2001-07-31 2999 9839 6C9E E4BF B540 C44B 4EC4 E1BE 5BA2 2F00 Every gun that is made, every warship launched, every rocket fired, signifies in the final sense a theft from those who hunger and are not fed, those who are cold and are not clothed. -- Dwight D.
