Kay Sievers ea6039a309 udev: allow firmware requests to bypass the dependency tracking 
The removal of the TIMEOUT= handling in udevd put firmware requests into the
devpath parent/child dependency tracking. Drivers which block in module_init()
asking userspace for firmware ran into a 30 sec device timeout.

The whole firmware loading willl hopefully move into the kernel and
the fragile-since-day-one fake async driver-core device dance involving
udev can be retired:

Lennart Poettering 01ed0e2307 dev-setup: make NULL as parameter for dev_setup() equivalent to "" 2012-08-21 17:23:03 +02:00
Dave Reisner 8f0e73f250 dev-setup: allow a path prefix for use in chroots 
With this adjustment, we can reuse this code elsewhere, such as in
nspawn.

Kay Sievers ef8a2bf648 udev: static nodes - fix default permissions if no rules is given 
<falconindy> kay: just curious -- it looks like nodes created by udev from
  modules.devname all have 000 perms, and there's nothing in udev that attempts
  to change this. is it intended?
<falconindy> c---------   1 root root     10, 223 Jul  1 23:10 uinput
<kay> falconindy: we might miss the default of 0600
<falconindy> seems like it
<kay> falconindy: stuff that has a rule works i guess
<kay> falconindy: i'll add the 0600 now

Dave Reisner ddbe6850b2 udevd: fix bogus mkdir invocation 
The filename parameter passed to mkdir can't contain anything but a
garbage value at this point. This was meant to be the full pathname to
the new udev DB, as the mkdir_parents() call before it won't create the
trailing child directory.

[replace mkdir_parents() + mkdir() with mkdir_p() -- kay]

Kay Sievers 145dae7eb3 udev: reset /proc/self/oom_score_adj in worker processes 
Only the main daemon process should be excluded from OOM handling,
not the worker processes or their child processes.

Kay Sievers d315bba6f6 udev: limit minimum worker count to 16 2012-06-04 16:40:31 +02:00
Lauri Kasanen a52289f7f5 udev: lower the starting children_max -> drop the minimum required RAM from 23mb to 5mb 
Udev was the limiting factor for us on low-RAM systems.
Given an average RSS of 180kb, 128 workers would require ~23mb of RAM.

Now, please consider what happens when there is only, say, 15mb free.
Udev protects itself from OOM, and the kernel can do nothing but panic.

28 workers * 0.18mb = ~5mb. This change should not affect more powerful
systems much, given that they still get the addition from the amount of RAM.

Kay Sievers 0f9963a8b8 Revert "label: fix systemd-udev labeling of /run directory." 
This reverts commit 9b5af248f0.

Udev now explicitely labels only files/directories in /dev. The selinux
array API is not released and will not work on other distros at this moment.

Kay Sievers d2e54fae5c mkdir: append _label to all mkdir() calls that explicitly set the selinux context 2012-05-31 12:40:20 +02:00
Daniel J Walsh 9b5af248f0 label: fix systemd-udev labeling of /run directory. 
systemd-udev is currently incorrectly labeling /run/udev/* content because it is
using selinux prefix labeling of /dev.  This patch will allow systemd-udev to
use prefix labeling of /dev and /run.
