[uml-devel] Patch - fix for segfault in uml_switch

[Steve B. <st...@sn...>]

I have been running UML with uml_switch (from uml_utilities_20021103) 
and I had a problem with it segfaulting when I brought UMLs down and 
then restarted them.

It turns out that when a port disconnects, the port is freed but the
entry is left in the hash table. If a new connection happens for the 
same device, it finds the garbage left in the hash table.

The following patch solves the problem, albeit not in the most elegant 
possible way.

Cheers,
Steve
