* traceroute: graceful recover after networking errors with as_serverEugene Grosbein2026-02-093-7/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currentlu, the traceroute[6] utility does not check for possible networking errors while talking to as_server in case of "traceroute -a". Meantime, there is a common case when trace is long and it has many non-responding hops (shown as '* * *'), so as_server aborts our connection, hence no AS numbers shown for the rest of trace. Somewhat artifical way to reproduce the problem: traceroute to 57.144.244.1 (57.144.244.1), 80 hops max, 48 byte packets 5 [AS174] be2950.ccr42.fra05.atlas.cogentco.com (154.54.72.42) 74.277 ms 9.605 ms 9.599 ms 6 [AS174] 149.11.228.19 (149.11.228.19) 9.506 ms 9.466 ms 9.420 ms 7 [AS33182] po172.asw02.fra5.tfbnw.net (129.134.108.146) 9.725 ms 9.874 ms 9.696 ms 8 [AS32934] psw04.fra5.tfbnw.net (157.240.59.85) 8.718 ms 8.691 ms 8.618 ms 9 * * * 10 [AS0] edge-star-mini-shv-01-fra5.facebook.com (57.144.244.1) 9.747 ms 9.815 ms 9.699 ms Note what due to increased timeout (-w10) we get [AS0] for 10th hop because as_server closed our connection. Same problem occurs with default -w3 when there are lots of '* * *' hops in a trace. Fix it with some additional error checking and a reconnection. This patch was in my use for many years and after traceroute(8) moved from contrib/ to usr.sbin/ it's nice to have it in the tree. MFC after: 2 weeks
* SPDX: Tag BSD-4.3TAHOEAlexander Ziaee2025-05-211-0/+3
| | | | | | | | | | | | | | TIL traceroute.8 has one of the oldest liceses, predating BSD-4-Clause! The SPDX tag was not even on Wikipedia. These are all the files I could find in the tree with git grep that look like the license reported on the SPDX website, including one that was misfiled.

* traceroute tests: fix the test when SCTP is supportedLexi Winter2025-05-161-6/+0
| | | | | | | | | | | | | | | | The SCTP test assumes a default system configuration where SCTP is not supported, so the probe packet returns an ICMP error which is displayed as a !P response. If SCTP is supported, then something else is returned instead (depending on exactly what probe we sent, but not an ICMP error) and the test fails. Since we already check the correct probes are sent using tcpdump, remove the match for the second hop entirely.

* traceroute: add testsLexi Winter2025-05-053-0/+890
| | | | | | | | | | | | | | | | | | add some basic tests for traceroute. this covers most of the flags we can easily test; in some cases we use tcpdump to ensure the correct packets are actually being sent. to run the tests, we create three jails: one for the source host, one for the destination host, and one to route packets betweem them. this ensures we're actually testing traceroute across a routed network and not just sending probe packets to a directly connected host. no tests for traceroute6 are in this commit since the traceroute6 merge into traceroute is in progress elsewhere.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Swapping byte order on SOCK_RAW was actually a bug, an artifact from the BSD network stack, that used to convert a packet to native byte order once it is received by kernel. Other operating systems didn't follow this, and later other BSD descendants fixed this, leaving us alone with the bug. Now it is clear that we should fix the bug.
