[Pkg-vsquare-devel] Bug#484295: vde2: vde_switch segfaults on vlan related CLI commands on AMD64

[Bjørn Mork]

Package: vde2
Version: 2.2.0-pre2-1
Severity: important

I can consistently make vde_switch segfault by using a CLI sequence like this:

 bjorn at canardo:~$ vde_switch 
 
 vde$ vlan/create 42
 1000 Success
 
 vde$ vlan/allprint
 Segmentation fault


There are many other combinations which will achieve the same result.  The effect
is that it is impossible to configure the virtual switches with any non-default
vlans.  Using a configuration file at switch startup has the same crashing effect.

The switch does still function as expected for a non-managed switch, so this bug
does not render it completely useless.  But the usability is severely limited.

I've tested on an i386 system, and cannot reproduce the bug there.  Given the 
implemantions dependency on the sizeof(long), I assume this makes it a 64bit
bug.  Will attempt to fix it and provide a patch if I can.  Just wanted to register
this bug first in case someone is working on it, or someone can point me to
some configuration error on my side.
