35b7d88c0d [PATCH] udevd - next round of fixes
Here is the next round. We have three queues now. All incoming messages
are queued in msg_list and if nothing is missing we move it to the
running_list and exec in the background.
If the exec comes back, it removes the message from the running_list and
frees the message.

Before we exec, we check the running_list if there is a udev running on
the same device path. If yes, we move the message to the delay_list. If
the former exec comes back, we move the message to the running_list and
exec it.

The very first event is delayed now to catch possible earlier sequences,
every following event is executed without delay if no sequence is missing.

The daemon doesn't exit by itself any longer, cause we don't want to
delay every first exec.

I've put a $(PWD) for now in the Makefile for testing this beast. Only
the local binaries are executed, not the /sbin/udev. We can change it
if we are ready for real testing.

And SIGKILL can't be cought, so I removed it from the handler :)

87171e46cd [PATCH] udevinfo - now a real program :)
I want to make udevinfo the standard query interface, so all the user
features of the main udev are copied in here. It is now capable to:

  o query the database for a given value
  o dump the whole database
  o extract all possible device attributes for a sysfs_device


In addition to the known options of udev it supports the query for the
mode of the device node, and it includes the mode in the database dump:

  udevinfo -d
  P: /class/video4linux/video0
  N: video/webcam0
  M: 0666
  S: camera0 kamera0
  O: 500
  G: 500


It is also a bit more friendly with the pathnames specified for devices or nodes.
We remove the absolute path or add it if neccessary:

  udevinfo -q mode -n video/webcam0
  udevinfo -q mode -n /udev/video/webcam0
  0666

  udevinfo -q mode -p /sys/class/video4linux/video0
  udevinfo -q mode -p /class/video4linux/video0
  udevinfo -q mode -p class/video4linux/video0
  0666

Here is the next revision for udevd:
  o Small cleanups all over the place.
  o Swich to the usual linked list format "list.h".
  o Better timeout handling.
      We store a timestamp in in every queued event, so we don't wait longer
      than the timeout specified, if the hole in the list is not shrinking.
  o ignore udevd target if klibc is used

33db4b8da0 [PATCH] udev - next round of udev event order daemon
Here is the next round of udevd/udevsend:

udevsend - If the IPC message we send is not catched by a receiver we fork
           the udevd daemon to process this and the following events

udevd    - We reorder the events we receive and execute our current udev for
           every event. If one or more events are missing, we wait
           10 seconds and then go ahead in the queue.
           If the queue is empty and we don't receive any event for the next
           30 seconds, the daemon exits.
           The next incoming event will fork the daemon again.

config   - The path's to the executable are specified in udevd.h
           Now they are pointing to the current directory only.


I don't like daemons hiding secrets (and mem leaks :)) inside,
so I want to try this model. It should be enough logic to get all possible
hotplug events executed in the right order.

If no event, then no daemon! So everybody should be happy :)


Here we see:
  1. the daemon fork,
  2. the udev work,
  3. the 10 sec timeout and the skipped events,
  4. the udev work,
     ...,
  5. and the 30 sec timeout and exit.

034f35d7e6 [PATCH] udev - udevinfo with device chain walk
udevinfo is now capable to print "all" attributes along the device chain
of a sysfs device. Just like udev itself it walks the chain upwards and
prints all usable attributes in the udev key format.
So it should be easy to find unique attributes to compose a rule.

All multiline attribute values and values containing non printable
characters are skipped now. I hope nothing useful gets lost with this :)

NOTE:
  The BUS value corresponding with the attributes is printed for every
  device. Don't specify BUS= in a rule and mix SYSFS_attributes from
  different busses, the rule can't match.

Here is the next updated updated version to apply to the lastet udev.
I've added infrastructure for getting the state of the IPC queue in the
sender and set the program to exec by the daemon. Also the magic key id
is replaced by the usual key generation by path/nr.

It looks promising, I use it on my machine and my 4in1 USB-flash-reader
connect/disconnect emits the events "randomly" but udevd is able to
reorder it and calls our normal udev in the right order.

Also a few more trivials:
  o added the defaults to udev.conf.in
  o removed class_dev from get_default_mode(), to match with Hanna's
  o changed size of mode_str to MODE_SIZE
  o changed a few char compares from from 0x00 to '\0'

74c73ef994 [PATCH] set default owner/group in db.
This patch fixes a bug where the udev database stored empty strings
for Owner and Group if they were default. This patch stores the default
value into the database if not set otherwise. See example output:


crw-------    1 root     root       4,  65 Jan 16 11:13 ttyS1

P: /class/tty/ttyS1
N: ttyS1
S:
O: root
G: root

This is a bit of a hack. However, until udev supports setting the
o/g values they will be root/root anyway so the database might as
well reflect the truth instead of empty strings.

Here is a slightly better version. I've created a logging.h file and
moved the debug macros from udev.h in there.

If you type:

  'make'            - you will get a binary that prints one or two lines to syslog
                      if a device node is created or deleted

  'make LOG=false'  - you get a binary that prints asolutely nothing

  'make DEBUG=true' - the same as today, it will print all debug lines

5e4f123888 [PATCH] minor patch for devfs rules
I've attached a patch that adds a few rules to udev.rules.devfs, making it
look a little more like devfs on my system. (I have the sysfs patches from
2.6.1-rc1-mm2) I added rules for oss, misc, floppy, and input devices. The
oss rules look like trouble with a wildcard at the end of each name, but I'm
not sure how I can make it any better.

Devfs has a bunch of other devices in the floppy directory for floppies
formatted in unusual ways, but I don't see them in udev. Not that I ever used
them, since they're usually automatically detected.
