[PATCH] udev - drop all methods :)
> 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
