[Bug 1354704] Re: traceroute --mtu doesn't work on recent kernels
The fact that the fix for LP: #1354704 relies on the fix for LP: #1330558 from 2.0.20, and that the other changes in 2.0.20 are very small and introduce no new features, makes me think it is worth uploading the complete new version rather than cherry-picking the fix for the --mtu option alone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1354704 Title: traceroute --mtu doesn't work on recent kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/traceroute/+bug/1354704/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1354704] Re: traceroute --mtu doesn't work on recent kernels
** Description changed: + [SRU] The debdiff attached to comment #4 backports traceroute 1:2.0.20-2 from Utopic to Trusty and fixes the following bugs present in 1:2.0.19-3 in Trusty: + - Fix segfault with --mtu (LP: #1330558) + - Fix --mtu on recent kernels (LP: #1354704) + + [IMPACT] + Users of traceroute in Trusty are unable to make use of the --mtu option to discover the MTU along the path being traced. This works fine in Precise. + + [Test Case] + Run traceroute with the --mtu option, e.g.: + traceroute --mtu 8.8.8.8 + + Expected behaviour: a regular traceroute of the path to the host is + printed, including F=NUM at the hops where the MTU is reached. + + Actual behaviour (in Trusty): segmentation fault. + + [Regression Potential] + Minimal: traceroute is recommended by netperfmeter, subnetcalc and xorp, and depended on by libnet-traceroute-perl and zentyal-network. + + - + Running traceroute with the --mtu option gives strange output on recent kernels: $ traceroute --mtu 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 65000 byte packets 1 * 0.015 ms * 0.007 ms * 0.006 ms 2 * 0.006 ms * 0.007 ms * 0.006 ms 3 * 0.006 ms * 0.006 ms * 0.006 ms 4 * 0.006 ms * 0.008 ms * 0.007 ms 5 * 0.007 ms * 0.006 ms * 0.006 ms I see similar numbers up to hop 30 and they appear almost instantly. In Sid, Ubuntu Utopic and Ubuntu Trusty, traceroute 2.0.20 produces output as above but 2.0.19 and 2.0.18 all segfault (as in #750759) with the --mtu option. In Ubuntu Precise (kernel 3.2), traceroute 2.0.18, 2.0.19 and 2.0.20 all work correctly with the --mtu option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1354704 Title: traceroute --mtu doesn't work on recent kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/traceroute/+bug/1354704/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
