2010-12-10udevd: use dev_t or netif ifindex as database keyKay Sievers
We need to preserve the database of network interfaces while we rename them. Use the kernel's numbers wherever possible, instead of the device names. Fix wrong database filenames which contain a '/', translated from '!' in the kernel name. Fix segfault for kobject pathes where the subsystem can not be determined from sysfs.

2010-04-21more readlink buffer size handlingKay Sievers
2010-04-21remove buffer-overrun risk in readlink callMathias Nyman
readlink does not write a nul character to the end of the string it returns. Therefore ask for one fewer character than the buffer size so there's always room for an extra \0.

2010-04-13remove "ignore_remove" optionKay Sievers
2010-04-13remove "all_partitions" optionKay Sievers
We can not predict the major/minor of non-existing devices: $ grep . /sys/class/block/sd*/dev /sys/class/block/sda1/dev:259:524288 /sys/class/block/sda2/dev:259:262144 /sys/class/block/sda3/dev:259:786432 /sys/class/block/sda4/dev:259:131072 /sys/class/block/sda/dev:259:0 /sys/class/block/sdb/dev:259:655360 /sys/class/block/sdc/dev:259:393216 If this functionality is still needed for some broken hardware, it needs to be solved with a tool not part of the udev package. Because such option is unreliable and unsafe to use.

2010-01-13do not remove device nodes of active kernel devicesKay Sievers
We do no longer delete the primary device node while handling "remove" events if the same kernel device is already re-created in the meantime. This prevents the asynchronously running udev from removing and re-creating primary device nodes for active devices.

2009-11-03fix major fd leak in link handlingMartin Pitt
link_find_prioritized(): Properly close directory handles to fix a major fd leak which caused hotplugging to fail entirely in many cases due to having too many open files. https://launchpad.net/bugs/463347
2009-10-28break loops if util_create_path() returns errorKay Sievers
Dangling symlinks in path components return -ENOENT. Do not retry to create the file in a loop in such case.

2009-09-10reorder create_path() and node/link creation to be called in a direct sequenceKay Sievers
2009-09-09simplify "symlink name stack"Kay Sievers
With well defined and kernel-supplied node names, we no longer need to support a possible stack of conflicting symlinks and node names. Only symlinks with identical names can be claimed by multiple devices. This shrinks the former /dev/.udev/names/ significantly. Also the /dev/{block,char}/MAJ:MIN" links are excluded from the name stack - they are unique and can not conflict.
2009-08-19change database file namesKay Sievers
With very deeply nested devices, We can not use a single file name to carry an entire DEVPATH. Use <subsystem>:<sysname> as the database filename, which should also simplify the handling of devices moving around, as these values will not change but still be unique. For the name stack we use the <maj>:<min> now as the filename. > On Tue, Aug 18, 2009 at 09:59:56AM -0400, Ric Wheeler wrote: > The first is that udev grumbles during boot about "file name too long" > like the following: > > Aug 17 06:49:58 megadeth udevd-event[20447]: unable to create db file > '/dev/.udev/db/\x2fdevices\x2fpci0000:00\x2f0000:00:04.0\x2f0000:17:00.0\x2f0000:18:0a.0\x2f0000:1f:00.0\x2fhost11\x2fport-11:0\x2fexpander-11:0\x2fport-11:0:0\x2fexpander-11:1\x2fport-11:1:0\x2fexpander-11:2\x2fport-11:2:17\x2fexpander-11:3\x2fport-11:3:1\x2fend_device-11:3:1\x2fbsg\x2fend_device-11:3:1': > File name too long
2009-08-01update a few years of copyrightKay Sievers
2009-05-20use more efficient string copyingKay Sievers
2009-05-04handle devtmpfs nodesKay Sievers
UDev follows the kernel given name, and re-uses the kernel created device node. If the kernel and spcecified udev rules disagree, the udev specified node node is created and the kernel-created on is deleted.
2009-04-26drop "extern" keyword from non-static functionKay Sievers
2009-04-19udevd: at startup create /dev/null, /dev/console, /dev/kmsgKay Sievers
2009-01-16remove name from index if the node name has changedKay Sievers
Scott discovered that a changed rule, which renames a device node leaves the old node name around as a symlink. So drop the reference to the old name.
2009-01-15udevadm: test - remove --force optionKay Sievers
Since a while we change the database with a "test" run, but do not update the node and symlinks. We need to "force" all the time, to keep things in sync.
