ifIndex overflow (Linux Kernel - net/core/dev.c) [maybe offtopic]

[Daniel Preussker <daniel () preussker net>]

Hi,

I was looking into the net/core/dev.c from the current Kernel (previous also have this) and found out that ifIndex gets 
incremented by an endless loop.

After creating 4 billion pseudo-eth devices I finally got it to overflow and endless loop, had to kill the kernel - fun 
right?



General question, is this known?
