Bug ID: 210286
Summary: Traceroute6 does not timeout in the continued presence
of echo replies
Product: Base System
Version: 10.3-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin

Diff to fix traceroute6
If traceroute6 is run and one of the hops is not responding, receipt of an IPv6
ICMP echo reply will cause traceroute6 to re-execute the wait on the current
probe. If echo replies are coming in at a rate faster than the timeout,
traceroute6 will essentially wait forever on the non responding hop.
This can be easily reproduced using ping6 and traceroute6 simultaneously in the
presence of non responsive hops.
A diff which corrects the problem is attached.
