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.

[Unit]
units: drop "(Varlink)" We generally don't specify the protocol implementation in unit descriptions. For journald, we have: $ git grep Description 'units/*journald*' units/systemd-journald-audit.socket:Description=Journal Audit Socket units/systemd-journald-dev-log.socket:Description=Journal Socket (/dev/log) units/systemd-journald-varlink@.socket:Description=Journal Varlink Socket for Namespace %i units/systemd-journald.service.in:Description=Journal Service units/systemd-journald.socket:Description=Journal Sockets units/systemd-journald@.service.in:Description=Journal Service for Namespace %i units/systemd-journald@.socket:Description=Journal Sockets for Namespace %i so we need to keep "Varlink" in the name. But also use "Sockets" (plural) for the "main" socket unit, since it opens multiple sockets.

DefaultDependencies=no
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.

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.

# Mount and swap units need this. If this socket unit is removed by an isolate
# request the mount and swap units would be removed too, hence let's exclude
# systemd-journald and its sockets from isolate requests.

journal: move sockets into their own subdir

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.

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 01:07:49 +01:00
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 00:00:27 +01:00

log: increase socket buffers for logging by default

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.

units/systemd-{udevd,journald}*.socket: enable DeferTrigger= Refer to d766c75acdd825abe1bcfd45406ae2e609a008b6 for the rationale behind the udevd change. systemd-journald.service conflicts with soft-reboot.target, so make sure anything surviving soft-reboot and trying to log to journal doesn't fail the socket units.
