Bug 80596 – modprobe ip_conntrack fails with "Kernel BUG" segfault

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Thierry Carrez (RETIRED) 2005-02-03 09:02:26 UTC]

Using hardened-dev-sources-2.6.10-r3, when I try to modprobe ip_conntrack (or when shorewall does) it dies with the messages shown in this screen capture :

tseng: can you reproduce it ?
I'll try what happens if ip_conntrack is compiled in.

It used to work using the 2.6.7-series.

Compiling ip_conntrack inkernel apparently workarounds this bug.
tseng: feel free to close it if you can't reproduce it.

I am getting this same error with kernel 2.6.12-gentoo-r6 when ip_conntrack is a
module.  Then all module activity is hosed and I have to reboot.

I will also try to compile the iptables modules in-kernel and see if this helps.  

But, short of that, this should work as a module and investigation should be
done on this to sort out why this module is causing a seg fault.

Is this reproducible on 2.6.15? If so, please enable CONFIG_KALLSYMS so that backtraces become useful.

Please reopen when you respond to comment #3
