Bug#718490: More info
Seems that lo0, pflog0 and pfsync0 can be checked. I think I managed to debug some but not sure if it is useful. $ gdb ifconfig GNU gdb (GDB) 7.6 (Debian 7.6-5) Copyright (C) 2013 Free Software Foundation, Inc.

I admit I am not a very experience debian hacker but I tried adding this to ifconfig.c and rebuild the package with dpkg-buildpackage. BUILDDIR/sbin/ifconfig/ifconfig still segfaults though so I have not tried to replace the standard package yet. 2013/8/1 Petr Salinger petr.salin...@seznam.cz Seems similar to http://bugs.debian.org/cgi-**bin/bugreport.cgi?bug=696514http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=696514 Yes I thought so at first, but this feature seems to be working on 8.3 and 9.0 kernels so it is likely a kernel ABI change instead.
