iptables-1.8.2-dont_read_garbage.patch
Hello,
In SUSE we bumped into a bug where iptables doesn't work with our
kernel-default-base package that was missing bpfilter module:
<a href="https://bugzilla.suse.com/show_bug.cgi?id=1106751">https://bugzilla.suse.com/show_bug.cgi?id=1106751</a>
As a part of this bug, Fabian Vogt discovered that this was actually handled
wrongly also in iptables itself as a missing memset(&info, 0, sizeof(info)); in
libiptc.c caused it to read garbage.
He proposed a patch that I'm attaching.
For more information please read the mentioned bug (mainly comments 0, 1, 6).
Thanks!</pre>
