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 00:20:58 +02:00			`# under the terms of the GNU Lesser General Public License as published by`

use /run instead of /dev/.run Instead of the /dev/.run trick we have currently implemented, we decided to move the early-boot runtime dir to /run. An existing /var/run directory is bind-mounted to /run. If /var/run is already a symlink, no action is taken. An existing /var/lock directory is bind-mounted to /run/lock. If /var/lock is already a symlink, no action is taken. To implement the directory vs. symlink logic, we have a: ConditionPathIsDirectory= now, which is used in the mount units. Skipped mount unit in case of symlink: $ systemctl status var-run.mount var-run.mount - Runtime Directory Loaded: loaded (/lib/systemd/system/var-run.mount) Active: inactive (dead) start condition failed at Fri, 25 Mar 2011 04:51:41 +0100; 6min ago Where: /var/run What: /run CGroup: name=systemd:/system/var-run.mount The systemd rpm needs to make sure to add something like: %pre mkdir -p -m0755 /run >/dev/null 2>&1 \|\| : or it needs to be added to filesystem.rpm. Udev -git already uses /run if that exists, and is writable at bootup. Otherwise it falls back to the current /dev/.udev. Dracut and plymouth need to be adopted to switch from /dev/.run to run too.

umask: set umask of a number of sockets by default, even though we check creds on connections 2011-08-01 22:42:07 +02:00			`SocketMode=0600`
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			`PassSecurity=yes`
