relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends. 2012-04-12 02:20:58 +04:00			`# under the terms of the GNU Lesser General Public License as published by`

service: ignore dependencies on $syslog and $local_fs in LSB scripts We no longer allow early-boot init scripts, however in late boot the syslog socket and local mounts are established anyway, so let's simplify our dep graph a bit. If $syslog doesn't resolve to syslog.target anymore there's no reason to keep syslog.target around anymore. Let's remove it. Note that many 3rd party service unit files order themselves after syslog.target. These will be dangling dependencies now, which should be unproblematic, however. 2013-01-17 00:09:03 +04:00			`Before=sockets.target`

units: add IgnoreOnIsolate=yes to systemd-journald too We already had it on the socket units, so it's possible that systemd-journald.service would be stopped and then restarted when trafic hits the sockets when something logs. Let's not try to stop it. It is supposed to run until the end and be eventually killed in the final killing spree. This might (or not) help with #23287. 2022-06-29 14:14:37 +03:00			`# Mount and swap units need this. If this socket unit is removed by an isolate`

journal: move sockets into their own subdir 2012-01-05 23:24:16 +04:00			`ListenDatagram=/run/systemd/journal/socket`
units: turn on timestamping for journald sockets To make things simple and robust when debugging journald, we'll leave the SO_TIMESTAMP invocations in the C code in place, even if they are now typically redundant, given that the sockets are already passed into the process with SO_TIMESTAMP turned on now. 2020-10-26 19:41:06 +03:00			`ListenStream=/run/systemd/journal/stdout`
socket: rename the PassCred= option to PassCredentials=, since we don't want to needlessly abbreviate options unless they are very well established 2011-12-31 04:07:49 +04:00			`PassCredentials=yes`
socket: add option for SO_PASSEC https://bugzilla.redhat.com/show_bug.cgi?id=798760 (Note that this work is not complete yet, as the kernel seems to send us useless data with SCM_SECURITY enabled) 2012-03-13 03:00:27 +04:00			`PassSecurity=yes`

journald: move /dev/log socket to /run This way we can make the socket also available for sandboxed apps that have their own private /dev. They can now simply symlink the socket from /dev. 2014-06-04 18:37:02 +04:00			`Service=systemd-journald.service`
