* ttymsg: OverhaulDag-Erling Smørgrav2026-05-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | * Instead of an error string, return the usual 0 or -1 and let the caller figure out what, if anything, to tell the user. * Avoid string manipulations by opening /dev first and using openat() with O_RESOLVE_BENEATH. * Add a boolean argument which, if false, causes ttymsg() to return without sending the message if the tty's group-writable bit is not set. This saves programs that respect this setting (like syslogd(8)) from having to check before calling ttymsg(). * Update all callers. The observable effect of this change is minimal except for slightly different error messages when ttymsg() fails. However, syslogd(8) will no longer print spurious error messages on the console after trying and failing to write a log message to an X11 session.

* Remove copyright strings ifdef'd outWarner Losh2023-11-271-8/+0
| | | | | | | | | | | We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3.
