libnetfilter conntrack: problem in nfct_callback_register

libnetfilter conntrack: problem in nfct_callback_register

[Julien VEHENT]

[-- Attachment #1: Type: text/plain, Size: 765 bytes --]

Hi All,

I'm coding with the libnetfilter-conntrack in C and, for some unexpected 
reasons, my program use to crash (could be after a few minutes or a few 
hours) with the following message:

> api.c:137: nfct_callback_register: Assertion `h != ((void *)0)' failed.

AFAIK, "h" is the library handler defined by nfct_open(CONNTRACK, 0) and used 
in nfct_callback_register, nfct_query and nfct_close.

But I have no idea how to debug that....

I'm using the following libs on Debian Lenny:
>libnetfilter-conntrack-dev    0.0.50-1
>libnetfilter-conntrack1       0.0.50-1

I pasted my code here: http://rafb.net/p/nz33XI27.html

This drives me crazy... It's probably just a stupid mistake but I don't see 
it...

Thanks for your help,

Julien

First of all, please update the libs. A major rewrite has occur and lots
of bug have been fixed. Please also nota that the API has changed.

Last version can be downloaded from:
http://netfilter.org/projects/libnetfilter_conntrack/downloads.html

Hi,

I'm probably asking too much, but do you have any .deb version of the 
library ?
I would rather prefer to keep the integrity of my system.

Thanks,

Julien

It looks like the packages are getting close to being in 'sid', however
as of right now, are not. Once they are, you can use apt pinning to pull
them in, or wait for them to migrate from 'sid' to 'lenny'.

Otherwise, you could build from source and install to /usr/local/, which
is what I would do.

Sorry for the delay but the library are now available for etch from
http://packages.inl.fr/ in their latest release.

You can add to your sources.list:
deb http://packages.inl.fr/ stable/
