[PATCH] udev_volume_id: remove temporary node creation and parent handling
udev can create the temporary node for us now. (On bootup we don't
know where a writable filesystem is mounted). Also the parent handling
is not needed anymore, cause udev is able to pass us the node name
of the parent device.
We are already using %u in the sscanf() format string.
The patch replaces the int for the kernel release number with
unsigned int, as we can never have negative release numbers.
[PATCH] namdev: allow symlink-only rules to specify node permissions
First case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", SYMLINK="cdrecorder", MODE="0666"
brw-rw---- 1 root disk 22, 0 Feb 5 14:08 /dev/hdc
Second case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", MODE="0666"
brw-rw-rw- 1 root disk 22, 0 Feb 5 14:08 /dev/hdc
Move code into a .c-file instead of big inline functions in a header file.
Pass the device name down instead of relying that the node name is equal
to the kernel name.
The -d option in udev_allows to go from a partition to the underlying disk
for s390 dasd labels. If the device is already the disk itself, finding the
parent will fail, therefore -d on /sys/block/dasda/ for example gives no
result at all.
If the system reaches a defined limit of processes in running state, udevd
starts to count its own processes in running state from its session (all
forked hotplug child processes, subprocesses and callouts) and throttles
further process forking if the limit is reached.
This should help setups with hundreds of events emitted hotplug events
in parallel with hundreds of processes in "R" state. which makes the machine
unresponsible.
I placed a 100% cpu time consuming program in /etc/hotplug.d/ which runs for 5
seconds. With this patch I can load "scsi_debug add_host=100" without any major
problem. Without the patch the box is completly unresponsible for many minutes.
Fix FAT label reading bug for very large volumes.
Recognize FAT label at Win98 formatted volumes.
Read iso9660 joliet descriptor for unicode labels.
Support uuid/label of swap partitions.
We delay the execution of events if there is already an event running for
the same device, a parent or a child device. "add" events with a reference
to a physical device will also wait for the physical device to finish.
Here we fix the devpath comparison logic to return "busy" only if a complete
device names is matching. /block/sdaa will not longer block a /block/sda event.
[PATCH] limit the initial timeout of the udevd event handling
Define an inititialization phase, where we delay the events only
for a short time to eventually recollect the event sequence instead
of delaying the very first events for 10 seconds, which breaks the
firmware loader.

[PATCH] handle renamed network interfaces properly if we manage hotplug.d/
If we take over the hotplug call and manage the events we don't need
to call the event fake script in dev.d/. Just set all expected values
to the new network interface name and call hotplug.d/. This way the
device renaming is completely handled inside of udev and userspace
can't get confused.

- Move the description of the environment variables to a new section
called "ENVIRONMENT" (as stated in man(7))
- Pointer to the "official" udev homepage
- Fixes for various typos and whitespace damages
/sbin/udevstart segfaults on an ATIIXP chipset which is not supported
well by the kernel yet. There, /proc/ide/hda/media can not be read
(EIO error) and udevstart seems to give a null-pointer to an SELinux
function checking the media-type.
[PATCH] udevd-test.pl: remove wrong date calculation
A hour wrap during the test run does not work :) Just remove
all the useless date conversions as we are only interested in the
seconds it takes to process.
[root@pim udevd-test]# ./udevd-test.pl 9
...
device: /class/tty/console, action: remove
forking udev time: Sat Dec 11 18:59:57 2004
the delay time is: 3 s
device: /class/tty/ptmx, action: remove
forking udev time: Sat Dec 11 19:00:07 2004
the delay time is: 4013 s
the delay time is: 4013
udevd doesn't act properly.

[PATCH] prevent udev node creatinon for "class" registration
I've found a /dev/video4linux node and just realized, that libsysfs
searches all subdirs for an attribute name.
So it found /class/video4linux/video0/dev for the videodev class
creation event /class/video4linux and created a node.
