For renamed network interfaces, the udev socket message header
contained the original devpath, which we have updated in the
environment after the kernel has silently renamed the netif.
Identified by Joachim Plack <jplack@suse.de> while working around
the problem that the device nodes appear and disappear while the
partitiontable is re-read and the application need to waait for an
empty udevd queue.
Apply substitutions before running a program, not while the rule
is parsed. It allows to use environment variables set during rule
processing as command arguments.
We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

This allows scripts to do:
while test -d /dev/.udev/queue; do sleep 0.1; done
And don't create a failed symlink if there is another event
for the same devpath in the queue.
All udev state is kept in /$udev_root/.udev/ now. No option to
configure that anymore, it will always be there.

All pending and running events can be found as symlinks to the actual
device in /dev/.udev/queue/ now. This way we can lookup if specific events
are still in the queue, before doing actions which require events to have
finished.
All failed event processes can be found in /dev/.udev/failed/. This makes
it possible to retry a failed event process at a later time in the boot
process.

With removing the event reorder queue, we can fix the TIMEOUT events
like firmware loading proper, and never delay any of these events.

Netlink will never get out-of-order and we just depend on it from
now on. Udevsend messages will have no effect if they contain a
sequence number (SEQNUM).
Thanks to Bastian Blank <waldi@debian.org>, for the debugging session
which identified a bug where the timeouts are not working if
inotify was not available. All the timeout handling is removed
now and this issue should be solved.

It was a workaround for speed up udev "coldplug", where ~800 events
happened a second time during bootup. No need for it with the rules
aleady parsed in the daemon.

Move socket init and rule parsing before forking, so we can start
emitting event immediately after udevd has started.
Signed-off-by: Kay Sievers <kay.sievers@vrfy.org>
The rules files are parsed only once at daemon startup. Every udev
event process will be fork()'d from udevd without exec()'ing the udev
binary. The in-memory rules will be inherited from the daemon itself.
If inotify is available, udevd will reload all rules if any change in
/etc/udev/rules.d/ happens. Otherwise -HUP or "udevcontrol reload_rules"
can be used.

Netlink events get lost when the kernel creates thousends of events
faster than udevd reads it. The default is 128 KB, which can carry
app. 500 events. Set it to 16 MB now.
I have 4000 fibrechannel LUNs connected to my system. There are two
paths to the devices and two ports on the host connected via a switch.
This gives 16000 when probed.
I have had problems getting all of the entries in /dev created.
