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.

Changing the default values in udev.conf will render allmost all current systems unusable. So just remove the settings that can't be changed anyway. Signed-off-by: Kay Sievers <kay.sievers@suse.de>

Yeah, I guess it's broken. In create_node() in udev_add.c there is always added 1 to the minor number, thus the error. The attached patch should fix this.
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] udev selinux fixpebenito@gentoo.org
Here is a fix for the SELinux part of udev. Setfscreatecon() overrides the default labeling behavior of SELinux when creating files, so it should only be used for as short of a time as possible, around the mknod or symlink calls. Without this, the files in udev_db get the wrong label because the fscreatecon is reset after the udev_db file creation instead of before. I'm guessing the Redhat people missed this because they modify udev_db to be one big file instead of a directory of small files (at least that's what I'm told). I created selinux_resetfscreatecon() to reset the fscreatecon asap after the file/node is created. Fixed a memory leak in selinux_init. Getfscreatecon() allocates memory for the context, and the udev code was immediately setting the pointer (security_context_t is actually a typedef'ed char*) to NULL after the call regardless of success/failure. If you're wondering about the case where there's effectively a setfscreatecon(NULL), this is ok, as its used to tell SELinux to do the default labeling behavior. Renamed selinux_restore() to selinux_exit() due to the changed behavior. Fixed a couple of dbg() messages.

2005-04-26[PATCH] introduce OPTIONS=ignore_device, ignore_remove, all_partitions" keykay.sievers@vrfy.org
Here we move all possible options into a own key to make it possible to have options-only rules. The options on the NAME key are removed from the man page and will be removed from a future version of udev. For ignore rules, OPTIONS="ignore" should be used. The rule: SUBSYSTEM="block", SYSFS{removable}="1", OPTIONS="all_partitions" will create all partitions for a block device which is known to have removable media (a check for cdrom drives would be needed too).

2005-04-26[PATCH] selinux: cleanup udev integrationkay.sievers@vrfy.org
Move code into a .c-file instead of big inline functions in a header file. Pass the device name down instead of relying that the node name is equal to the kernel name.
2005-04-26[PATCH] The attached patch fixes the code path if namedev_name_device() fails.mbuesch@freenet.de
2005-04-26[PATCH] handle renamed network interfaces properly if we manage hotplug.d/kay.sievers@vrfy.org
If we take over the hotplug call and manage the events we don't need to call the event fake script in dev.d/. Just set all expected values to the new network interface name and call hotplug.d/. This way the device renaming is completely handled inside of udev and userspace can't get confused.
2005-04-26[PATCH] simplify permission applicationkay.sievers@vrfy.org
We have only one source of permissions now, so apply the default permissions at udev init.
2005-04-26[PATCH] rename udev_lib to udev_utils and dev_d to udev_multiplexkay.sievers@vrfy.org
2005-04-26[PATCH] rename udevdb* to udev_db*kay.sievers@vrfy.org
2005-04-26[PATCH] Make dev.d/ handling a separate processing stagekay.sievers@vrfy.org
Move the logic when and how to call the dev.d/ scripts into the main processing path.
2005-04-26[PATCH] replace tdb database by simple lockless file databasekay.sievers@vrfy.org
This makes the udev operation completely lockless by storing a file for every node in /dev/.udevdb/* This solved the problem with deadlocking concurrent udev processes waiting for each other to release the file lock under heavy load.
2005-04-26[PATCH] improve klibc fixup integrationkay.sievers@vrfy.org
2005-04-26[PATCH] $local userkay.sievers@vrfy.org
We once implemented the devfsd feature to set the owner of a device node to the "local" user. This was before we had the dev.d/ scripts. We discussed a similar issue with D-BUS recently and this should be better handled depending on the distributions way to do such a thing. I'm for removing this here as this can be easily covered by a dev.d/ script. Here is the patch if nobody objects :)
2005-04-26[PATCH] cleanup netif handling and netif-dev.d/ eventskay.sievers@vrfy.org
Here we supress the dev.d/ execution if we didn't change a network interface's name with a rule. This should solve the issue of two running dhclients for the same interface, cause the /etc/dev.d/net/hotplug.dev script that fakes the hotplug event runs with every udevstart for every interface and fakes a second identical hotplug event on bootup. With this patch netif interfaces are no longer stored in the udevdb. It is not needed, cause we don't have permissions or symlinks :) and all information is available in sysfs. This patch also moves the dev_d execution calls out of the udev_add/udev_remove. As with the former api-cleanup-patch we have all processed data in one udev struct and can place the execution calls where needed.
2005-04-26[PATCH] big cleanup of internal udev apikay.sievers@vrfy.org
Here is the first patch to cleanup the internal processing of the various stages of an udev event. It should not change any behavior, but if your system depends on udev, please always test it before reboot :) We pass only one generic structure around between add, remove, namedev, db and dev_d handling and make all relevant data available to all internal stages. All udev structures are renamed to "udev". We replace the fake parameter by a flag in the udev structure. We open the class device in the main binaries and not in udev_add, to make it possible to use libsysfs for udevstart directory crawling. The last sleep parameters are removed.
2005-04-26[PATCH] remove sleeps from udev as it is external nowkay.sievers@vrfy.org
Here we remove all the sysfs sleep loops from udev as wait_for_sysfs will do this for us and any other hotplug user. We still keep a small blacklist of subsystems we don't care about but any missing entry here will no longer lead to a spinning udev waiting for files.
2005-04-26[PATCH] prevent deadlocks on an corrupt udev databasekay.sievers@vrfy.org
Here is the patch, that should prevent all of the known deadlocks with corrupt tdb databases we discovered. Thanks to Frank Steiner <fsteiner-mail@bio.ifi.lmu.de>, who tested all this endlessly with a NFS mounted /dev. The conclusion is, that udev will not work on filesystems without proper record locking, but we should prevent the endless loops anyway. This patch implements: o recovery from a corrupted udev database. udev will continue without database support now, instead of doing nothing. So the node should be generated in any case, remove will obviously not work for custom names. o added iteration limits to the tdb-code at the places we discovered endless loops. In the case tdb tries to find more than 100.000 entries with the same hash, we better give up :) o prevent a {all_partitions} loop caused by corrupt db data o log all tdb errors to syslog o switch sleep() to usleep() cause we want to use alarm()
