Bug ID: 255507
Summary: traceroute6 generates wrong UDP checksum
Product: Base System
Version: 13.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
Environment: FreeBSD stable/13 host A and FreeBSD host B, connected via router.
This can be reproduced.
Steps to repeat:
1. traceroute6 -nq1 IP6_address_on_host_B
2. On host B, netstat -sp udp | grep 'bad checksum', it shows increasing
statistic counter. It can be verified by tcpdump -npvi nic 'ip6 && udp' .
Note:
* If host A is directly connected with host B, then the UDP checksum is
correct.
* Some system other then FreeBSD seems not checking UDP checksum before
generating ICMP time exceeded, thus to repeat it host B should be FreeBSD
system.
