2011-04-21udevd, udev-event: sync waitpid() error handlingKay Sievers

2011-04-13udevadm: control - add --exitKay Sievers
2011-04-08selinux: do not label files in runtime dirKay Sievers
Do not label any files in the udev runtime directory, but only nodes, links and directories below /dev. In case the runtime directory falls back to /dev/.udev, label this directory once at udevd startup, but never anything below it.
2011-03-31udevd: add 'N:' to optstring in getopt_longThomas Egerer
2011-03-23systemd: bind udev control socket in systemd and split udev.serviceKay Sievers
We should bind the udev socket from systemd, so we are sure that the abstract namespace socket is always bound by a root process and there is never a window during an update where an untrusted process can steal our socket. Also split the udev.service file, so that the daemon can be updated/restarted without triggering any coldplug events.
2011-03-23use /run/udev/ if possible and fall back to /dev/.udev/Kay Sievers
2011-03-23udevd: initialize fds, for proper close() on exitKay Sievers
2011-03-23udevd: use facility == LOG_DAEMON when writing to /dev/kmsgKay Sievers
Syslog wants to distinguish the sorce of messages. We should indicate that this is a userspace message (LOG_DAEMON) and not a kernel message (LOG_KERNEL).

2010-11-22udevd: create static nodes before /dev/null is neededMichal Soltys
2010-10-13udevd: do not wrongly delay events for devices with swapped namesKay Sievers
Renaming network devices might delay events for the other device, which has the same devpath in the meantime as the original event. Causing a delay until the timout of the event is reached. Look at the ifindex/devnum of the devices to check if they are really the same devices.
2010-10-07udevd: add sd-daemon.cKay Sievers
2010-08-25Add support for oom_score_adjLuca Tettamanti
/proc/<pid>/oom_adj has been deprecated (kernel v2.6.36) due to the rework of the badness heuristic; oom_score_adj is the replacement. Keep a fallback to the old interface for compatibility with older kernels. See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=a63d83f427fbce97a6cea0db2e64b0eb8435cd10 Signed-off-by: Martin Pitt <martin.pitt@ubuntu.com>

2010-08-08udevd: create static device links only when the target existsYin Kangkai
For example, not all systems have PROC_KCORE enabled. Avoid a broken symbolic link in those cases. Signed-off-by: Yin Kangkai <kangkai.yin@intel.com> Signed-off-by: Martin Pitt <martin.pitt@ubuntu.com>

2010-05-11udevd: reload config only for *.rules filesKay Sievers
2010-04-26udevd: always try to find an idle worker instead of forking a new oneKay Sievers
We special-handle events with a TIMEOUT= set, so they don't get queued or wait for parent events to finish, to make sure we can handle them as fast as possible. With this change we first try to find an idle worker process before forking a new one.
2010-04-12replace "add|change" with "!remove"Kay Sievers
2010-01-13udevd: inotify - do not parse rules at create but at closeKay Sievers
We do not need to get notified about created files, only about moved ones or files closed-after-writing.
2009-12-25remove UDEV_RUN environment variableKay Sievers
It handles only RUN but not IMPORT and PROGRAM. There is no sane way to suppress program execution. Most important programs run with IMPORT these days. Also events can no longer suppressed with the libudev netlink messages, so UDEV_RUN does nothing useful and is just inconsistent.
2009-12-15remove remaining support for CONFIG_SYSFS_DEPRECATEDKay Sievers
2009-11-16remove "ignore_device"Kay Sievers
There is no way to ignore an event these days. Libudev events can not be suppressed. It only prevents RUN keys from being executed, which results in an inconsistent behavior in current setups.
