Fix for /proc/net/route OOPS none

Description Josh Bressers 2005-04-12 12:46:34 EDT
The fib_seq_start function in fib_hash.c in Linux kernel allows local
users to cause a denial of service (system crash) via /proc/net/route.

I have already submitted the fix for this for RHEL4 inclusion.
I'll attach it here,  but can someone verify that it got put
into the RHEL4 tree already?
