2005-04-26[PATCH] udev - drop all methods :)kay.sievers@vrfy.org
> Hi, > as promised yesterday, here is a patch that drops the explicit methods > given in the udev config and implement only one type of rule. > > A rule now consists only of a number of keys to match. All known keys > are valid in any combination. The former configs should work with a few > changes: > > o the "<METHOD>, " at the beginning of the line should be removed > > o the result of the externel program is matched with RESULT= instead if ID= > the PROGRAM= key is only valid if the program exits with zero > (just exit with nozero in a script if the rule should not match) > > o rules are processed in order they appear in the file, no priority > > o if NAME="" is given, udev is instructed to ignore this device, > no node will be created > > > EXAMPLE: > > # combined BUS, SYSFS and KERNEL > BUS="usb", KERNEL="video*", SYSFS_model="Creative Labs WebCam*", NAME="test/webcam%n" > > # exec script only for the first ide drive (hda), all other will be skipped > BUS="ide", KERNEL="hda*", PROGRAM="/home/kay/src/udev.kay/extras/ide-devfs.sh %k %b %n", RESULT="hd*", NAME="%1c", SYMLINK="%2c %3c" > > > The udev-test.pl and test.block works fine here. > Please adapt your config and give it a try. > Here is a slightly better version of the patch. After a conversation with Patrick, we are now able to execute the PROGRAM and also match in all following rules with the RESULT value from this exec. EXAMPLE: We have 7 rules with RESULT and 2 with PROGRAM. Only the 5th rule matches with the callout result from the exec in the 4th rule. RULES: PROGRAM="/bin/echo abc", RESULT="no_match", NAME="web-no-2" KERNEL="video*", RESULT="123", NAME="web-no-3" KERNEL="video*", RESULT="123", NAME="web-no-4" PROGRAM="/bin/echo 123", RESULT="no_match", NAME="web-no-5" KERNEL="video*", RESULT="123", NAME="web-yes" RESULT: Jan 11 23:36:52 pim udev[26050]: namedev_name_device: process rule Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check PROGRAM Jan 11 23:36:52 pim udev[26050]: execute_program: executing '/bin/echo abc' Jan 11 23:36:52 pim udev[26050]: execute_program: result is 'abc' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: PROGRAM returned successful Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for RESULT dev->result='no_match', udev->program_result='abc' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: RESULT is not matching Jan 11 23:36:52 pim udev[26050]: namedev_name_device: process rule Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for KERNEL dev->kernel='video*' class_dev->name='video0' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: KERNEL matches Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for RESULT dev->result='123', udev->program_result='abc' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: RESULT is not matching Jan 11 23:36:52 pim udev[26050]: namedev_name_device: process rule Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for KERNEL dev->kernel='video*' class_dev->name='video0' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: KERNEL matches Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for RESULT dev->result='123', udev->program_result='abc' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: RESULT is not matching Jan 11 23:36:52 pim udev[26050]: namedev_name_device: process rule Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check PROGRAM Jan 11 23:36:52 pim udev[26050]: execute_program: executing '/bin/echo 123' Jan 11 23:36:52 pim udev[26050]: execute_program: result is '123' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: PROGRAM returned successful Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for RESULT dev->result='no_match', udev->program_result='123' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: RESULT is not matching Jan 11 23:36:52 pim udev[26050]: namedev_name_device: process rule Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for KERNEL dev->kernel='video*' class_dev->name='video0' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: KERNEL matches Jan 11 23:36:52 pim udev[26050]: namedev_name_device: check for RESULT dev->result='123', udev->program_result='123' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: RESULT matches Jan 11 23:36:52 pim udev[26050]: namedev_name_device: found matching rule, 'video*' becomes '' Jan 11 23:36:52 pim udev[26050]: namedev_name_device: name, 'web-yes' is going to have owner='', group='', mode = 0600
2005-04-26[PATCH] introduce format char 'k' for kernel-namekay.sievers@vrfy.org
Attached is a patch that introduces the format char 'k' to be replaced with the kernel name. I like to have it in a callout script. I've moved the build_kernel_name() back to namedev_name_device() since we don't expect it growing cause of 'sdaj' :)

2005-04-26[PATCH] D-BUS patch for udev-008david@fubar.dk
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.

2005-04-26[PATCH] get rid of the majority of the debug environment variables.greg@kroah.com
Now there are only 3 valid environment test variables. The rest can be specified with the config file.
2005-04-26[PATCH] add support for a main udev config file, udev.conf.greg@kroah.com
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.
2005-04-26[PATCH] Build failure - missing linux/limits.h include?arnd@arndb.de
On Tuesday 25 November 2003 00:12, Chris Larson wrote: > udev fails to compile here unless I'm doing a KLIBC build.  The reason > appears to be that the normal limits.h in the gcc inc dir doesn't pull > in linux/limits.h, whereas the limits.h out in the klibc include dirs > does.  I'd think it'd be best to add a #include <linux/limits.h> to > udev.h directly, since it uses PATH_MAX. No, don't include kernel headers directly if you can avoid it. The problem you are referring to seems to be with old tool chains, I have the same symptom with my s390 gcc-2.95/glibc-2.1.3. Including <sys/param.h> instead of <limits.h> seems to fix it.

2005-04-26[PATCH] more robust config file parsing in namedev.carnd@arndb.de
After getting a number of different crashes for udev reading broken udev.config files, I decided to try to make the parser a little more robust. The behaviour is changed to stop reading the configuration file and logging the broken entry instead of silently ignoring it (is that good? It's easy to just print and continue). All strcpy()'s to a fixed length string are now implicitly limited to the bounds of the target string. I kept the -ENODEV return code for now, not sure if there should be different ones.

2005-04-26[PATCH] major database cleanupsgreg@kroah.com
Now we standardise on a struct udevice to pass around, and store in the database. This cleaned up the database code a lot.
2005-04-26[PATCH] udev: mode should be mode_trml@tech9.net
Unix file modes should be stored in a mode_t, not a standard type. At the moment it is actually unsigned, in fact, not a signed integer. Attached patch does an s/int mode/mode_t mode/ and cleans up the results.
2005-04-26[PATCH] put config files and database in /etc/udev by defaultgreg@kroah.com
Can be overridden on the makefile line.
2005-04-26[PATCH] add callout config type to udevpatmans@us.ibm.com
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.
