I wonder if you could help me squash a bug in the tcp code.
Here is what we know thus far:
An SMP (x386 dual) 2.4.17 kernel crashes with an attempt to
deference NULL at the end of tcp_fragment() (in
net/ipv4/tcp_output.c) while attempting to link in the newly
created fragment.
The bugzilla report is:
%99 of all such bug reports turn out to be driver bugs
where the net driver frees SKBs improperly or there is some
missing internal locking in the net device driver.
I think you efforts are better spent auditing what net
drivers are being used on this machine :-)
