2007-03-18priority based symlink handlingKay Sievers
Symlinks can have priorities now, the priority is assigned to the device and specified with OPTIONS="link_priority=100". Devices with higher priorities overwrite the symlinks of devices with lower priorities. If the device, that currently owns the link goes away, the symlink will be removed, and recreated, pointing to the next device with the highest actual priority. This should solve the issue, that inserting an USB-stick may overwrite the /dev/disk/by-id/-link of another disk, and removes the entire link after the USB-stick is disconnected. If no priorities are specified, the new link will overwrite the current one, and if the device goes away, it will restore the old link. It should be possible to assign lower priorities to removable devices, if needed. In multipath setups, we see several devices, which all connect to the same volume, and therefore all try to create the same metadata-links. The different path-devices are combined into one device-mapper device, which also contains the same metadata. It should be possible, to assign multipath-table device-mapper devices a higher priority, so path-devices that appear and disappear, will not overwrite or delete the device-mapper device links.

2006-08-19consistent key naming to match only the event device or include all parent ↵Kay Sievers
devices This scheme is more consistent and makes it obvious if a match happens against the event device only, or the full chain of parent devices. The old key names are now: BUS -> SUBSYSTEMS ID -> KERNELS SYSFS -> ATTRS DRIVER -> DRIVERS Match keys for the event device: KERNEL SUBSYSTEM ATTR DRIVER (in a future release, for now the same as DRIVERS) Match keys for all devices along the parent device chain: KERNELS SUBSYSTEMS ATTRS DRIVERS ID, BUS, SYSFS are no longer mentioned in the man page but still work. DRIVER must be converted to DRIVERS to match the new scheme. For now, an error is logged, if DRIVER is used. In a future release, the DRIVER key behaviour will change.
2006-08-16rename udev_libc_wrapper -> udev_sysdepsKay Sievers
2006-08-13udevd: read DRIVER from the environmentKay Sievers
2006-07-06allow longer devpath valuesKay Sievers
2006-04-15apply format char to variables exported by ENVKay Sievers
2006-04-12remove old symlinks before creating current onesKay Sievers
This will prevent incorrect symlinks when a filesystem label is changed and the event is triggered again from sysfs.
2006-04-05merge device event handling and make database content available on "remove"Kay Sievers
2006-01-29optimize sysfs device and attribute cacheKay Sievers
Add negative cache for attributes and look for device in cache before doing any sysfs access. (Three times speed up for a stupid 1000 rules SYSFS file). Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2006-01-18scsi_id, usb_id: request device parent by subsystemKay Sievers
Request specific parents identified by subsystem and don't rely on a predefined sequence. Also let the devpath be longer than 72 chars, tsss ... Signed-off-by: Kay Sievers <kay.sievers@suse.de>

2006-01-09replace libsysfsKay Sievers
We never used any of the libsysfs convenience features. Here we replace it completely with 300 lines of code, which are much simpler and a bit faster cause udev(d) does not open any syfs file for a simple event which does not need any parent device information.

2005-11-16remove "udev_db" option from config fileKay Sievers
All udev state is kept in /$udev_root/.udev/ now. No option to configure that anymore, it will always be there. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-11-12remove all built-in wait_for_sysfs logicKay Sievers
Most of the issues are fixed with the kernel we depend on, for the remaing ones see the RELEASE-NOTES for a special rule to add. Signed-off-by: Kay Sievers <kay.sievers@suse.de>
2005-11-07udevd: depend on netlink and remove all sequence reorder logicKay Sievers
Netlink will never get out-of-order and we just depend on it from now on. Udevsend messages will have no effect if they contain a sequence number (SEQNUM). Thanks to Bastian Blank <waldi@debian.org>, for the debugging session which identified a bug where the timeouts are not working if inotify was not available. All the timeout handling is removed now and this issue should be solved. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

Any program can query with udevinfo for persistent device attributes evaluated on device discovery now. 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: move dev.d/ handling to external helperKay Sievers
Modern rules are expected to call notification and postprocessing with the RUN key. For compatibility the current behavior can be emulated with an external helper. 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>

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.
