ipsec issues - testers wanted
Hello list,
I would like to ask for assistance in identifying the conditions causing
the bug 283107. In short, it appears that the ipsec patch introduced in
2.4.27, makes the telnet connections fail under some unclear circumstances
on sparc64 (see bug trail [0] for details). I was able to reproduce the
problem on the submitter's machine (thanks for letting me fiddle with
it, Raoul) with pristine 2.4.27 kernel from www.kernel.org and ipsec
patch [1] applied (the problem is also seen in all 2.6 kernels too, since
ipsec patch is included with them). However, I could not reproduce it in
my environment, with a similar machine. Therefore I would like to ask for
help in identifying the combination of factors which makes the problem
happen. It would be particularly valuable if someone with an SMP Ultra
would give it a spin.
How (to try) to reproduce:
* Install the ipsec kernel [2]. Pristine kernel [3] is also provided for
comparison.
* Try telnetting to various hosts (they should run telnet server),
while capturing the packets with tcpdump -vvvx.
* If tcpdump log contains any messages about bad tcp checksums, or
the connections hang, send a report by replying to this thread.
