The +fix is needed for udisk2 to operate properly. + +Fix for skipped rule execution when the kernel has removed the device +node in /dev again, before the event was even started. The fix is needed +to run device-mapper/LVM events properly. + +Fix for the man page installation, which was skipped when xsltproc was not +installed. + +udev 179 +======== +Bugfix for $name resolution, which broke at least some keymap handling. + +udev 178 +======== +Bugfix for the firmware loading behavior with kernel modules which +try to load firmware in the module_init() path. The blocked event +runs into a timout now, which should allow the firmware to be loaded. + +Bugfix for a wrong DEVNAME= export, which breaks at least the udev-acl +tool. + +Bugfix for missing ID_ properties for GPT partitions. + +The RUN+="socket:.." option is deprecated and should not be used. A warning +during rules parsing is printed now. Services which listen to udev events, +need to subscribe to the netlink messages with libudev and not let udev block +in the rules execution until the message is delivered. + +udev 177 +======== +Bugfix for rule_generator instalation. + +udev 176 +======== +The 'devtmpfs' filesystem is required now, udev will not create or delete +device nodes anymore, it only adjusts permissions and ownership of device +nodes and maintains additional symlinks. + +A writable /run directory (ususally tmpfs) is required now for a fully +functional udev, there is no longer a fallback to /dev/.udev. + +The default 'configure' install locations have changed. Packages for systems +with the historic / vs. /usr split need to be adapted, otherwise udev will +be installed in /usr and not work properly. Example configuration options +to install things the traditional way are in INSTALL. + +The default install location of the 'udevadm' tool moved from 'sbin' +to /usr/bin. Some tools expect udevadm in 'sbin', a symlink to udevadm +needs to be manually created if needed, or --bindir=/sbin be specified. + +The expected value of '--libexecdir=' has changed and must no longer contain +the 'udev' directory. + +Kernel modules are now loaded directly by linking udev to 'libkmod'. The +'modprobe' tool is no longer executed by udev. + +The 'blkid' tool is no longer executed from udev rules. Udev links +directly to libblkid now. + +Firmware is loaded natively by udev now, the external 'firmware' binary +is no longer used. + +All built-in tools can be listed and tested with 'udevadm test-builtin'. + +The 'udevadm control --reload-rules' option has been renamed to '--reload'. +It now also reloads the kernel module configuration. + +The systemd socket files use PassCredentials=yes, which is available in +systemd version 38. + +The udev build system only creates a .xz tarball now. + +All tabs in the source code used for indentation are replaced by spaces now. :) + +udev 175 +======== +Bugfixes. + +udev 174 +======== +Bugfixes. + +The udev daemon moved to /lib/udev/udevd. Non-systemd init systems +and non-dracut initramfs image generators need to change the init +scripts. Alternatively the udev build needs to move udevd back to +/sbin or create a symlink in /sbin, which is not done by default. + +The path_id, usb_id, input_id tools are built-in commands now and +the stand-alone tools do not exist anymore. Static lists of file in +initramfs generators need to be updated. For testing, the commands +can still be executed standalone with 'udevadm test-builtin '. + +The fusectl filesystem is no longer mounted directly from udev. +Systemd systems will take care of mounting fusectl and configfs +now. Non-systemd systems need to ship their own rule if they +need these filesystems auto-mounted. + +The long deprecated keys: SYSFS=, ID=, BUS= have been removed. + +The support for 'udevadm trigger --type=failed, and the +RUN{fail_event_on_error} attribute was removed. + +The udev control socket is now created in /run/udev/control +and no longer as an abstract namespace one. + +The rules to create persistent network interface and cdrom link +rules automatically in /etc/udev/rules.d/ have been disabled by +default. Explicit configuration will be required for these use +cases, udev will no longer try to write any persistent system +configuration from a device hotplug path. + +udev 173 +======== +Bugfixes. + +The udev-acl extra is no longer enabled by default now. To enable it, +--enable-udev_acl needs to be given at ./configure time. On systemd +systems, the udev-acl rules prevent it from running as the functionality +has moved to systemd. + +udev 172 +======== +Bugfixes. + +Udev now enables kernel media-presence polling if available. Part +of udisks optical drive tray-handling moved to cdrom_id: The tray +is locked as soon as a media is detected to enable the receiving +of media-eject-request events. Media-eject-request events will +eject the media. + +Libudev enumerate is now able to enumerate a subtree of a given +device. + +The mobile-action-modeswitch modeswitch tool was deleted. The +functionality is provided by usb_modeswitch now. + +udev 171 +======== +Bugfixes. + +The systemd service files require systemd version 28. The systemd +socket activation make it possible now to start 'udevd' and 'udevadm +trigger' in parallel. + +udev 170 +======== +Fix bug in control message handling, which can lead to a failing +udevadm control --exit. Thanks to Jürg Billeter for help tracking +it down. + +udev 169 +======== +Bugfixes. + +We require at least Linux kernel 2.6.32 now. Some platforms might +require a later kernel that supports accept4() and similar, or +need to backport the trivial syscall wiring to the older kernels. + +The hid2hci tool moved to the bluez package and was removed. + +Many of the extras can be --enable/--disabled at ./configure +time. The --disable-extras option was removed. Some extras have +been disabled by default. The current options and their defaults +can be checked with './configure --help'. + +udev 168 +======== +Bugfixes. + +Udev logs a warning now if /run is not writable at udevd +startup. It will still fall back to /dev/.udev, but this is +now considered a bug. + +The running udev daemon can now cleanly shut down with: + udevadm control --exit + +Udev in initramfs should clean the state of the udev database +with: udevadm info --cleanup-db which will remove all state left +behind from events/rules in initramfs. If initramfs uses +--cleanup-db and device-mapper/LVM, the rules in initramfs need +to add OPTIONS+="db_persist" for all dm devices. This will +prevent removal of the udev database for these devices. + +Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of +120 seconds per process. If that timeout is reached the spawned +process will be killed. The event timeout can be overwritten with +udev rules. + +If systemd is used, udev gets now activated by netlink data. +Systemd will bind the netlink socket which will buffer all data. +If needed, such setup allows a seemless update of the udev daemon, +where no event can be lost during a udevd update/restart. +Packages need to make sure to: systemctl stop udev.socket udev.service +or 'mask' udev.service during the upgrade to prevent any unwanted +auto-spawning of udevd. +This version of udev conflicts with systemd version below 25. The +unchanged service files will not wirk correctly. + udev 167 ======== Bugfixes.
