* ttymsg: OverhaulDag-Erling Smørgrav2026-05-251-56/+64
| | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Add RFC 5424 syslog message output to syslogd.Ed Schouten2018-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move all of the code responsible for transmitting log messages into a separate function, fprintlog_write(). - Instead of manually modifying a list of iovecs, add a structure iovlist with some helper functions. - Alter the F_FORW (UDP message forwarding) case to also use iovecs like the other cases. Use sendmsg() instead of sendto(). - In the case of F_FORW, truncate the message to a size dependent on the address family (AF_INET, AF_INET6), as proposed by RFC 5426. - Move all traditional message formatting into fprintlog_bsd(). Get rid of some of the string copying and snprintf()'ing. Simply emit more iovecs to get the job done. - Increase ttymsg()'s limit of 7 iovecs to 32. Add a definition for this limit, so it can be reused by iovlist. - Add fprintlog_rfc5424() to emit RFC 5424 formatted log entries. - Add a "-O" command line option to enable RFC 5424 formatting. It would have been nicer if we supported "-o rfc5424", just like on NetBSD. Unfortunately, the "-o" flag is already used for a different purpose on FreeBSD. - Don't truncate hostnames in the RFC 5424 case, as suggested by that specific RFC. For people interested in using this, this feature can be enabled by adding the following line to /etc/rc.conf: syslogd_flags="-s -O rfc5424" Differential Revision: https://reviews.freebsd.org/D15011 Notes: svn path=/head/; revision=332510
* 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 copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.
