2005-04-26[PATCH] pattern match for label methodkay.sievers@vrfy.org
switch LABEL search to pattern match add a test for pattern match in LABEL remove useless rule from udev.rules
2005-04-26[PATCH] a bug in linefeed removalkay.sievers@vrfy.org
While I was adding pattern match to the LABEL method i hit a bug. We modify a string returned from libsysfs, so with every iteration is is truncated by one char: Dec 4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi' Dec 4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor' Dec 4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-ESXS ' Dec 4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-ESX' with '?IBM-ESXS' Dec 4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi' Dec 4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor' Dec 4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-ESX' Dec 4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-ES' with 'IBM-ESXS?'

2005-04-26[PATCH] fix permission handling logicgreg@kroah.com
Now we can handle wildcards properly within the permission file.
2005-04-26[PATCH] add support for the default_mode variable, as it is documented...greg@kroah.com
2005-04-26[PATCH] pattern matching for namedevkay.sievers@vrfy.org
As promised yesterday, here is a patch to implement a more advanced pattern matching instead of the simple '*'. We can remove the "tty"="tty" line from udev.rules now and replace "tty*" by "tty[0-9]*" to catch only the vc's. implement pattern matching in namedev '*' - to match zero or more chars '?' - to match exactly one char '[]' - character classes with ranges '[0-9]'and negation [!A]
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] split out the namedev config parsing logic to namedev_parse.cgreg@kroah.com
2005-04-26[PATCH] rename namedev's get_attr() to be main namedev_name_device() as ↵greg@kroah.com
that's what it really is.
2005-04-26[PATCH] catch replace device by wildcardkay.sievers@vrfy.org
catch device name by wildcard to support a whole class of devices by just one config line like: REPLACE, KERNEL="tty*", NAME="vc/%n"

2005-04-26[PATCH] Add format modifier for devfs like namingarnd@arndb.de

Anyone want to verify this or not? I would prefer to have the ability of creating partition nodes in devfs style built-in to udev. Devfs used to call the whole disk e.g. "/dev/dasd/0123/disk" and the partitions "/dev/dasd/0123/part[1-3]". This can obviously be done with a CALLOUT rule, but its common enough to make it a format modifier. AFAIK, this scheme has been used for ide, scsi and dasd disks, which is about 99% of all disks ever connected to Linux.
2005-04-26[PATCH] more config file parsing robustnessazarah@nosferatu.za.org
udev kept on segfaulting when it was in use, and not having the time (and building it with DEBUG=true showing nothing), I have not tracked it until tonight. Seems like I made a type-o, and forgotten the ':' between one line's group and permission parameters. Attached patch should stop the segfault, and warn at that at least.
2005-04-26[PATCH] namedev.c strcat tweakkay.sievers@vrfy.org
02-namedev.c-strcat-tweak.diff o cat the substitution to the already known end of the string instead of searching it another time

2005-04-26[PATCH] - format char for CALLOUT outputkay.sievers@vrfy.org
here is a patch for inserting the callout output into NAME=. ID= supports the usual wildcard to compare with the output. I've moved all wildcard matching to a function cause this was the third occurrence. Also attached is the last whitespace cleanup and debug text corrections. The callout patch depends on the whitespace patch.

2005-04-26[PATCH] namedev.c - change order of fields in CALLOUTkay.sievers@vrfy.org
I want to bring the CALLOUT field ordering in line with the other methods, cause the current parsing relies on the ordering it's good to have it like the others. The BUS= is now the first expected field. Also made the last two remaining field names to uppercase and the man page callout example is updated.

2005-04-26[PATCH] apply permissions.conf support for wildcard and default namekay.sievers@vrfy.org
Permissions given in udev.permissions are not applied if no METHOD from udev.config is found. I've added do_kernelname() to scan for known permissions if we only use the default method. Simple support for wildcards is also added: #name:user:group:mode hdb*:2702:2702:0660 results in: drwxr-xr-x 2 root root 240 Nov 19 03:45 . drwxr-xr-x 23 root root 528 Nov 17 03:36 .. brw-r--r-- 1 root root 3, 0 Nov 19 03:45 hda brw-r--r-- 1 root root 3, 1 Nov 19 03:45 hda1 brw-r--r-- 1 root root 3, 2 Nov 19 03:45 hda2 brw-r--r-- 1 root root 3, 4 Nov 19 03:45 hda4 brw-r----- 1 kay kay 3, 64 Nov 19 03:45 hdb brw-r----- 1 kay kay 3, 65 Nov 19 03:45 hdb1 brw-r--r-- 1 root root 22, 0 Nov 19 03:45 hdc crw-r--r-- 1 root root 81, 0 Nov 19 03:34 webcam0

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.

Great, just what I was missing. I didn't see the any link to the bk repository. Here's the patch for the bus_id. I'll need to think about the handling of callout results a bit more.
