Index: sys/net/route.c 4.2BSD Fix
Description:
The code for computing route table entry pointers in
rtrequest() is wrong. It will occasionally use negative
offsets, wreaking havoc. It is interesting to note that the
rest of the code in the same module does not have the bug.
Repeat-By:
Difficult; you need to add a route entry whose hash is a
negative number, and some negative values will sometimes
appear to work.
Fix:
The declaration for the variable ``hash'' should be an
unsigned integer. Find the line reading
int s, error = 0, hash, (*match)();
and move ``hash'' down a line onto the
u_int af;
declaration (or do what Berkeley did and make a new u_int line).
