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
include/linux/tcp.h | 2
include/linux/udp.h | 31 -
include/net/dst.h | 56 --
include/net/ip.h | 16
include/net/sock.h | 2
include/net/tcp.h | 2
include/net/udp.h | 2
net/core/dst.c | 25 -
net/ipv4/af_inet.c | 17
net/ipv4/icmp.c | 4
net/ipv4/ip_output.c | 880 +++++++---------------------------------------
net/ipv4/ip_proc.c | 74 ---
net/ipv4/ip_sockglue.c | 4
net/ipv4/raw.c | 7
net/ipv4/tcp.c | 49 --
net/ipv4/tcp_ipv4.c | 6
net/ipv4/tcp_minisocks.c | 10
net/ipv4/udp.c | 296 ---------------
net/ipv6/tcp_ipv6.c | 5
net/netsyms.c | 1
(this is the diffstat of the reverse patch)
Is this fixed already?
/B.

Hi,
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.
