This release represents a major refresh of the sysklogd project. The venerable syslogd gets an infusion of new blood from NetBSD and FreeBSD to fully support RFC3164 and RFC5424. Also included is a user library and a replacement for syslog.h to enable new features in RFC5424.

Note: as of this release klogd is disabled by default, syslogd can read Linux kernel messages on its own now.

Changes

• Support for true RFC3164 formatted log messages to remote log servers, including timestamp and hostname. Use ;RFC3161 rule option
• Support for RFC5424 from UNIX domain socket, from remote servers and also to remote servers. Requires new API syslogp() to unlock these features on the UNIX socket. Still compatible with GLIBC/musl/uClibc
• Support for options to syslog.conf rules. E.g. ;RFC5424 to enable sending/writing log messages with RFC3339 style timestamps, and more
• Support for include /etc/syslog.d/*.conf in syslog.conf
• New tool logger from the Finit project, BSD licensed. Supports all the features of RFC5424, so very useful for trying out the "new" standard
• Support for reading from a custom UNIX domain socket path, -p SOCK, for unit testing with logger -u /path/to/sock
• Support for sending to a custom port on a remote server, @host:port
• New syslogp() API from NetBSD, for applications wanting to use RFC5424 features like MsgID or structured data
• Many incompatible changes to command line options in syslogd and klogd for compatiblity with FreeBSD and NetBSD syslogd. Examples:
  • In syslogd: -b and -c have been replaced with -r for global log rotation, -a has been replaced with the new -p support. The -r flag and -s HOST has also been dropped in favor of the BSD -s flag to control two levels of secure mode. The -n flag is now -F and -n means something else entirely ... there's more
  • In klogd: -i and -I have been removed
• klogd is not built by default anymore, syslogd can read /proc/kmsg on Linux on its own. Reduces complexity and gives you one daemon less
• When systemd support is detected by the configure script the unit file(s) are now installed into the systemd system services folder
• Update COPYING file to GPL 2 rev 2, with new FSF address and other minor stuff
• Update license header in all files:
  • Sync 3-clause BSD license change with upstream NetBSD and FreeBSD sources
  • Sync GPL license header, new FSF address
  • Add SPDX license identifiers to all source files

Fixes

• Fix GCC 8 warnings; "too small destination buffer in snprintf()"
• Major code cleanup and rewrite inspired by both NetBSD and FreeBSD
  sources, e.g. removed all previous unit TESTING #ifdefs
