2013-07-08static-nodes: move creation of static nodes from udevd to tmpfilesTom Gundersen
As of kmod v14, it is possible to export the static node information from /lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format. Use this functionality to let systemd-tmpfilesd create the static device nodes at boot, and drop the functionality from systemd-udevd. As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev: * the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw) * ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)
2013-04-16nspawn: introduce the new /machine/ tree in the cgroup tree and move ↵Lennart Poettering
containers there Containers will now carry a label (normally derived from the root directory name, but configurable by the user), and the container's root cgroup is /machine/<label>. This label is called "machine name", and can cover both containers and VMs (as soon as libvirt also makes use of /machine/). libsystemd-login can be used to query the machine name from a process. This patch also includes numerous clean-ups for the cgroup code.

You can write much more than just one line with this call (and we frequently do), so let's correct the naming.

Setting children_max according to RAM leads to too much concurrent I/O.

Parameter -e is set without additional argument in getopt and this leads to segfault when calling 'systemd-udevd -e'.

2012-10-07udev: allow firmware requests to bypass the dependency trackingKay Sievers
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: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=abb139e75c2cdbb955e840d6331cb5863e409d0e

With this adjustment, we can reuse this code elsewhere, such as in nspawn.

<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
2012-07-02udevd: fix bogus mkdir invocationDave Reisner
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]

2012-06-04udev: limit minimum worker count to 16Kay Sievers
2012-06-04udev: lower the starting children_max -> drop the minimum required RAM from ↵Lauri Kasanen
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.
2012-05-31Revert "label: fix systemd-udev labeling of /run directory."Kay Sievers
This reverts commit 9b5af248f04b6cad8a5bca836e89a39e9f6823d9. 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.

2012-05-31label: fix systemd-udev labeling of /run directory.Daniel J Walsh
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.
