Description tlarsen 1999-04-20 03:09:42 UTC 
In the in_cksum routine in ping.c, the 'if' case to handle pings of odd
length incorrectly handles the final byte. The code in ping.c will work
for big-endian targets, but fails for little-endian builds.

For example:   ping -s 513 localhost

has 100% data loss, where ping -s 512 localhost does not, on x86.

Fixed (by porting Alexey Kuznetsov's version from iputils) in
netkit-base-0.10-30.
