2005-08-29check the udevdb before assigning a new %eKay Sievers
A second "add" event created a new enumeration with %e. Check the udevdb first and if a matching name is already used. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-28rename ...trailing_char() to ...trailing_chars()Kay Sievers
Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-28start to enforce plain ascii or valid utf8Kay Sievers
No device node or symlink can have other characters as plain readable ascii or valid utf8. The /dev/disk/by-label/* symlinks can no longer contain weird stuff read from untrusted sources. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-27don't store devpath in udevdb, we don't need itKay Sievers

2005-08-26store ENV{key}="value" exported keys in the databaseKay Sievers
Just like the IMPORT values are stored in the udev database the exported keys are stored in the udev database. The database is also imported on a remove event before the rules are matched. So it is possible to do: ACTION=="add", KERNEL=="sda", ENV{MY_DEVICE}="1234", RUN+="/bin/logger add $devpath" ACTION=="remove", ENV{MY_DEVICE}=="1234", RUN+="/bin/logger remove $devpath" Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-16ENV{TEST}=="1" compares and ENV{TEST}="1" sets the environmentKay Sievers
This can be uses to export stuff to the event environment or to carry a state from one rule to another, like enabling/disabling later rules conditionally. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-15cleanup some debug output and move to info level + unify select() loopsKay Sievers

Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-11allow logging of all output from executed toolsKay Sievers
If USE_DEBUG=true and udev_log="debug", all output of the forked programs to stdout and stderr is send to syslog. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-08-08switch some strlcpy's to memcpyKay Sievers
strlcpy counts the sourec string lengt and is therefore not suitable to copy a defined length of characters from one string to another. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-07-20make SYSFS{} usable for all devicesKay Sievers
Patch from: Hannes Reinecke <hare@suse.de>
2005-07-16allow rules to have labels and skip to next labelKay Sievers
This will allow us to have whole blocks of rules to skip conditionally. The following section creates the node "yes": GOTO="TEST" NAME="no" NAME="no2", LABEL="NO" NAME="yes", LABEL="TEST" NAME="no3"
2005-07-16thread unknown ENV{key} match as empty valueKay Sievers
This way we can run a rule if a certain key is not set by: ENV{key}="" or ENV{key}!="?*" Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-07-05pack parsed rules listKay Sievers
This cuts down our 600 rules file to 98 kb instead of 1.9 Mb memory or file-size with precompiled rules. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

Export the type of device from ata_id and scsi_id, also strip leading and trailing whitespace and substitute consecutive whitespace with a single underline char. From: Hannes Reinecke <hare@suse.de> Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-06-26store the imported device information in the udevdbKay Sievers

2005-06-25IMPORT=<file> allow to import a shell-var style config-fileKay Sievers
This allows to source-in a file into the udev environment to have the defined keys available for later processing by udev itself or the forked helper programs. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-06-24allow rules to be compiled to one binary fileKay Sievers
All the rule files can be compiled into a single file, which can be mapped into the udev process to avoid parsing the rules with every event. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2005-06-05udev: handle all events - not only class and block devicesKay Sievers
Handle all events with rules. If udev is expected to handle hotplug.d/ the exernal helper must be called. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-06-05udev: clear lists if a new value is assignedKay Sievers
Former values are cleared if SYMLINK=<value> is used. To add a value SYMLINK+=<value> is now needed. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-06-05udev: allow final assignments :=Kay Sievers
The use of KEY:=<value> will make the key unchangeable by later rules. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-04-26[PATCH] add RUN key to be able to run rule based notificationkay.sievers@vrfy.org
SUBSYSTEM=="block", RUN="/sbin/program" will execute the program only for block device events. ACTION="remove", SUBSYSTEM=="block", RUN"/sbin/program" will execute the program, if a block device is removed.

2005-04-26[PATCH] remove untrusted chars read from sysfs-values or returned by PROGRAMkay.sievers@vrfy.org
Better remove characters that are useless in a device node name. It may be a security risk to pass any character read from e.g. a sysfs attribute to a shell script we execute later. Prevent the modification of the libsysfs attribute value cache. Clear PROGRAM result if the execution encountered an error.
