2005-04-26[PATCH] switch device type to enumkay.sievers@vrfy.org
2005-04-26[PATCH] switch major/minor to dev_tkay.sievers@vrfy.org
2005-04-26[PATCH] remove the device node only if the major/minor number matcheskay.sievers@vrfy.org
2005-04-26[PATCH] create /block/*/range count of partitons for all_partitionskay.sievers@vrfy.org
2005-04-26[PATCH] provide temporary device node for callouts to access the devicekay.sievers@vrfy.org
%N will create a temporary node for a callout a be sustituted with the name of the node.
2005-04-26[PATCH] rename udev_lib to udev_utils and dev_d to udev_multiplexkay.sievers@vrfy.org
2005-04-26[PATCH] add NAME{ignore_remove} attributekay.sievers@vrfy.org
Some broken ide drivers are generating high event traffic, with add/remove events. With this attribute, it can be specified, that the node is always available. It may be used in conjunction with the new DRIVER= match to catch specific kernel device drivers.
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] sparse cleanups on the treegreg@kroah.com
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] 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()
2005-04-26[PATCH] rename files to have '_' instead of '-' in them.greg@kroah.com
We should be consistent in our madness...
