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

Software such as dracut performs a sanity check on udev by querying the
udev tools for the version. Reporting the eudev version causes this
check to fail, so we resort to reporting the udev compatibility
versionj.

Clang 3.1 indicated that we had implicitly declared several, which is
illegal in C99.

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:

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

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]

Only the main daemon process should be excluded from OOM handling,
not the worker processes or their child processes.

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.

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.

context
|
|
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.
