Hmm, Arndt Bergmann sent a patch like this one a few weeks ago and
I want to bring the question back, if we want to handle net device
naming with udev.
With this patch it is actually possible to specify something like this
in udev.rules:
KERNEL="dummy*", SYSFS{address}="00:00:00:00:00:00", SYSFS{features}="0x0", NAME="blind%n"
KERNEL="eth*", SYSFS{address}="00:0d:60:77:30:91", NAME="private"
and you will get:
[root@pim udev.kay]# cat /proc/net/dev
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
lo: 1500 30 0 0 0 0 0 0 1500 30 0 0 0 0 0 0
private: 278393 1114 0 0 0 0 0 0 153204 1468 0 0 0 0 0 0
sit0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
blind0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
The udevinfo program is also working:
[root@pim udev.kay]# ./udevinfo -a -p /sys/class/net/private
looking at class device '/sys/class/net/private':
SYSFS{addr_len}="6"
SYSFS{address}="00:0d:60:77:30:91"
SYSFS{broadcast}="ff:ff:ff:ff:ff:ff"
SYSFS{features}="0x3a9"
SYSFS{flags}="0x1003"
SYSFS{ifindex}="2"
SYSFS{iflink}="2"
SYSFS{mtu}="1500"
SYSFS{tx_queue_len}="1000"
SYSFS{type}="1"
follow the class device's "device"
looking at the device chain at '/sys/devices/pci0000:00/0000:00:1e.0/0000:02:01.0':
BUS="pci"
ID="0000:02:01.0"
SYSFS{class}="0x020000"
SYSFS{detach_state}="0"
SYSFS{device}="0x101e"
SYSFS{irq}="11"
SYSFS{subsystem_device}="0x0549"
SYSFS{subsystem_vendor}="0x1014"
SYSFS{vendor}="0x8086"
The matching device will be renamed to the given name. The device name
will not be put into the udev database, cause the kernel renames the
device and the sysfs name disappears.
I like it, cause it plugs in nicely. We have all the naming features
and sysfs queries and walks inside of udev. The sysfs timing races
are already solved and the management tools are working for net devices
too. nameif can only match the MAC address now. udev can match any sysfs
value of the device tree the net device is connected to.
But right, net devices do not have device nodes :)

there.

Is there any reason to parse the rules for a remove event?
Without it, our test script needs only 2.1 seconds instead of 2.5,
so we have 19 percent more time for testing now :)
|
|
Here we replace the various fgets() with a mmap() call for the config
file reading, due to the reported performance problems with klibc.
Thanks to Patrick's testing, it makes a very small, close to nothing
speed gain for libc users, but a 6 times speed increase for klibc users
with a 1000 line config file.
I've created a udev_lib.[hc] for this and also moved all the generic
stuff from udev.h in there and uninlined the functions.
|
|
Here I try to make the style a bit more consistant in the different
files, so that new patches just copy the 'right' one :)
Some "magic" numbers are replaced and udevtest.c is catched up with udev.
|
|
Is this something for the blacklist?
/sys/class/pcmcia_socket/
|-- pcmcia_socket0
| |-- device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:00.0
| `-- driver -> ../../../bus/pci/drivers/yenta_cardbus
`-- pcmcia_socket1
|-- device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:00.1
`-- driver -> ../../../bus/pci/drivers/yenta_cardbus

Mainly a cleanup of the earlier patches with a few missing pieces
and some cosmetical changes.
I've moved the udev_init_config() to very early init, otherwise we
don't get any logging for the processing of the input. What would I
do without gdb :)
Greg, it's the 7th patch in your box to apply. I will stop now and
wait for you :)
|
|
Here we truncate our input strings from the environment to our
defined limit. It's a bit theroretical but better check for it.
It cleans up some magic length definitions and removes the code
duplication in udev, udevtest and udevsend.
udevd needs to be killed after installation, cause the message size
is changed with this patch.
Should we do this with the 'make install', like we do with the '.udevdb'?
|
|
I was on the train for 5 hours today and the TODO is almost empty :)
So, at least four people wanted this feature, then here is a actual
working patch.
We may specify now in udev.conf:
udev_rules="/etc/udev/"
and udev will scan the whole directory for files ending with *.rules,
sort it in lexical order and create our rule list from all of the files.
A plain given file will still work and the same applies to the *.permissions.
I sort the files in our usual linked list, cause klibc has no scandir().

external one.
Should fix some more build bugs...
|
|
Use the new location of libsysfs header files.
|
|
Also fix up some other dependancy issues in the Makefile.
Thanks to Olaf Hering <olh@suse.de> for pointing them out.

So here is the next try :)
hpa, for good reason, didn't like my changes to klibc.
He will dump signal() completely from klibc instead, so here we switch to
sigaction() and keep udevd working with klibc.

Also introduce boolean type for config file to use.

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 :)

Here we get the ability to query with the name of the node instead of
the device path. It uses a linear search over the whole database.
kay@pim:~/src/udev.kay$ ./udev -q path -n video/webcam0
/class/video4linux/video0
New version, with better function return codes for error handling.

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

This patch improves the user options for udev.
It is possible now to query for the name, the symlinks or owner/group.
If asked for the name of the node we are able to prepend the udev_root
with the -r option.
SAMPLE:
kay@pim:~/src/udev.test$ ./udev -V
udev, version 012_bk
kay@pim:~/src/udev.test$ ./udev -h
Usage: [-qrVh]
-q <name> query database for the specified value
-p <path> device path used for query
-r print udev root
-V print udev version
-h print this help text
kay@pim:~/src/udev.test$ ./udev -r
/udev/
kay@pim:~/src/udev.test$ ./udev -q name -p /class/video4linux/video0
video/webcam0
kay@pim:~/src/udev.test$ ./udev -q symlink -p /class/video4linux/video0

Yes, I can try.
There was no way to tell not to do anything so I created one. Errors
are signalled via negative return values, so I thought that a positive,
non-zero one could mean to ignore the device. I don't like it but
perhaps you have a better solution.

This one is nothing important, just add some quotes to be more consistent
with the rest and make sure that the return value is positive (since the
error return values are negative). Hmm?

Thanks to Kay for the original patch, and the idea.
|
|
As usual, here is the corresponding man page update and
a small text correction.
|

Here is a slightly better version that prints the usage if a unknown option is given:
kay@pim:~/src/udev.kay$ ./udev -x
./udev: invalid option -- x
Usage: [-qrVh]
-q arg query database
-r print udev root
-V print udev version
-h print this help text

enough stuff.

Here's a patch that adds a signal handler to udev to
clean up the environment (close the sysbus and close
the database) on kill-signals.
|
|
Seems like we need the following patch to do
proper sysbus cleanup, if udevdb_init() fails.

#ifdef crud from the main code.

Attached is a patch against udev-008 to send out a D-BUS message when a
device node is added or removed.
Using D-BUS lingo, udev acquires the org.kernel.udev service and sends
out a NodeCreated or NodeDeleted signal on the
org.kernel.udev.NodeMonitor interface. Each signal carries two
parameters: the node in question and the corresponding sysfs path.
[Note: the D-BUS concepts of service, interface, object can be a bit
confusing at first glance]
An example program listening for these messages looks like this
#!/usr/bin/python
import dbus
import gtk
def udev_signal_received(dbus_iface, member, service, object_path, message):
[filename, sysfs_path] = message.get_args_list()
if member=='NodeCreated':
print 'Node %s created for %s'%(filename, sysfs_path)
elif member=='NodeDeleted':
print 'Node %s deleted for %s'%(filename, sysfs_path)
def main():
bus = dbus.Bus(dbus.Bus.TYPE_SYSTEM)
bus.add_signal_receiver(udev_signal_received,
'org.kernel.udev.NodeMonitor', # interface
'org.kernel.udev', # service
'/org/kernel/udev/NodeMonitor') # object
gtk.mainloop()
if __name__ == '__main__':
main()
and this is the output when hot-plugging some usb-storage.
[david@laptop udev-008]$ ~/node_monitor.py
Node /udev/sda created for /block/sda
Node /udev/sda1 created for /block/sda/sda1
Node /udev/sda1 deleted for /block/sda/sda1
Node /udev/sda deleted for /block/sda
The patch requires D-BUS 0.20 or later while the python example program
requires D-BUS from CVS as I only recently applied a patch against the
python bindings.

Now there are only 3 valid environment test variables. The rest can be
specified with the config file.
|
|
the older udev.config file is now called udev.rules.
This allows us to better control configuration values, and move away from
the environment variables.
|
|
be LSB compliant
Finally the Debian people can get off my back...
|

01-overall-whitespace+debug-text-conditioning.diff
o cleanup whitespace
o clarify a few comments
o enclose all printed debug string values in ''

and udev.config
the namedev name didn't really make much sense anymore...
|
|
|
|
config variables
This will make running tests a lot simpler.
|
|
|
|
This patch adds a callout config type to udev, so external programs can be
called to get serial numbers or id's that are not available as a sysfs
attribute.
|
|
This patch:
1) removes the three database files for just one udevdb.tdb file.
2) adds udevdb_init() and udevdb_exit() functions
3) initializes database now in main() in udev.c.
Please look it over.

needs lots more cleanup, but is much nicer than doing this by hand...
