2005-04-26[PATCH] add a "old style" SYSFS_attribute test to udev-test.plgreg@kroah.com
2005-04-26[PATCH] udev - switch callout part selector to {attribute}kay.sievers@vrfy.org
Here we change the magic callout part number selector to the new atribute syntax. The syntax to select the second part of the callout string: '%2c' is now '%c{2}' I think it's more clear and we no longer misuse the length argument. The old syntax is still supported, but we should remove it some time in the future.
2005-04-26[PATCH] udev - switch SYSFS_file to SYSFS{file}kay.sievers@vrfy.org
Here we switch the configs and man pages to the new attribute syntax. Also the 'partition trick' is mentioned in udev.8 I think it's more clear visible now, that inside the brackets are user supplied values used and not some magic keys handled: 'SYSFS_dev' is now 'SYSFS{dev}' The old syntax is still supported.
2005-04-26[PATCH] udev add some ID testspatmans@us.ibm.com
Patch against current udev bk to add a few ID rule tests.
2005-04-26[PATCH] udev - create all partitions of blockdevicekay.sievers@vrfy.org
Here is the first try to create all partitons of a blockdevice, since removable media devices may need to acces the expected partition to revalidate the media. It uses the attribute syntax introduced with the last %s{file} patch. I'm using this with my multi-slot-flash-card-reader: SYSFS{model}="USB Storage-SMC ", NAME{all_partitions}="smartmedia" SYSFS{model}="USB Storage-CFC ", NAME{all_partitions}="compactflash" SYSFS{model}="USB Storage-MSC ", NAME{all_partitions}="memorystick" SYSFS{model}="USB Storage-MMC ", NAME{all_partitions}="multimedia" and I get: tree /udev/ /udev/ |-- memorystick |-- memorystick1 |-- memorystick10 |-- memorystick11 |-- memorystick12 |-- memorystick13 |-- memorystick14 |-- memorystick15 |-- memorystick2 |-- memorystick3 |-- memorystick4 |-- memorystick5 |-- memorystick6 |-- memorystick7 |-- memorystick8 |-- memorystick9 |-- multimedia |-- multimedia1 |-- multimedia10 |-- multimedia11 |-- multimedia12 |-- multimedia13 |-- multimedia14 |-- multimedia15 |-- multimedia2 |-- multimedia3 |-- multimedia4 |-- multimedia5 |-- multimedia6 |-- multimedia7 |-- multimedia8 |-- multimedia9 ... If needed, we can make the number of partions to create adjustable with the attribute?

Better patch with infrastructure to easily implement KEY{attribute} for every other key. The first user is the SYSFS{file} key. Both versions, brackets or underscore is supported for the attribute.

The parsing of the format length '%3x' and the '%x{attribute}' is a fuction now, maybe there are more possible users in the future. I've also added the test to udev-test.pl.
2005-04-26[PATCH] Add another test to udev-test.pl and fix a bug when only running 1 test.greg@kroah.com
2005-04-26[PATCH] let udev-test.pl run an individual test if you ask it to.greg@kroah.com
just put the test number on the command line: udev-test.pl 3 will run test number 3 If no test number is specified, all of the tests will be run, just like before.
2005-04-26[PATCH] add a block device with a ! in the name, and a test for this.greg@kroah.com
2005-04-26[PATCH] fix log option code so that it actually works for all udev programs.greg@kroah.com
Also introduce boolean type for config file to use.

Please recheck it. Test script is switched to work on subsystem 'test' to let udev ignore it.

Next cleaned up version. Hey, nobody wants to try it :) Works for me, It's funny if I connect/disconnect my 4in1-usb-flash-reader every two seconds. The 2.6 usb rocks! I can connect/diconnect a hub with 3 devices plugged in every second and don't run into any problem but a _very_ big udevd queue.
2005-04-26[PATCH] udevd - next round of fixeskay.sievers@vrfy.org
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 :) 06:58:36 sig_handler: caught signal 15 06:58:36 main: using ipc queue 0x2d548 06:58:37 message is still in the ipc queue, starting

2005-04-26[PATCH] new testd.block script for debugging.greg@kroah.com
2005-04-26[PATCH] udev - next round of udev event order daemonkay.sievers@vrfy.org
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!

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.
2005-04-26[PATCH] add support for figuring out which device on the sysfs "chain" the ↵greg@kroah.com

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

o change the parsing to get a key from the rule and sort it into our list of known keys instead of expecting a special order o the key to match a sysfs file must be prependend by 'SYSFS_' now to match with the new parsing. (The config must be changed, but it's a bit more descriptive too.) o put names of fields in define's, like the name of the methods o update all tests and the man page
2005-04-26[PATCH] get part of callout return stringkay.sievers@vrfy.org
Try this patch if you like, to get special parts of the callout output. This beast works now: CALLOUT, BUS="scsi", PROGRAM="/bin/echo -n node link1 link2", ID="node *", NAME="%1c", SYMLINK="%2c %3c" The callout returned string is separated by spaces and is addressed by the "len" value of the 'c' format char. Since we support symlinks, this my be useful for other uses of callout too. introduce 'len number' for format chars the first use is 'c'-the callout return to select a part of the output string like: CALLOUT, BUS="scsi", PROGRAM="/bin/echo -n node link1 link2", ID="node *", NAME="%1c", SYMLINK="%2c %3c" (note: first part is requested by len=1, len=0 will return the whole string) add a test to udev-test.pl
