No common distro uses this option anymore, +and we do not get enough testing for this and recent udev versions. If +this option is not needed to run some old distro with a new kernel, +it should be disabled in the kernel config. + +Bugfix for the $links substitution variable, which may crash if no links +are created. This should not happen in usual setups because we always +create /dev/{block,char}/ links. + +The strings of the parsed rules, which are kept in memory, no longer +contain duplicate entries, or duplicate tails of strings. This, and the +new rules parsing/matching code reduces the total in-memory size of +a huge distro rule sets to 0.08 MB, compared to the 1.2MB of udev +version 130. + +The export of DEVTYPE=disk/partition got removed from the default +rules. This value is available from the kernel. The pnp shell script +modprobe hack is removed from the default rules. ACPI devices have _proper_ +modalias support and take care of the same functionality. +Installations which support old kernels, but install current default +udev rules may want to add that to the compat rules file. + +Libvolume_id now always probes for all known filesystems, and does not +stop at the first match. Some filesystems are marked as "exclusive probe", +and if any other filesytem type matches at the same time, libvolume_id +will, by default, not return any probing result. This is intended to prevent +mis-detection with conflicting left-over signatures found from earlier +file system formats. That way, we no longer depend on the probe-order +in case of multiple competing signatures. In some setups the kernel allows +to mount a volume with just the old filesystem signature still in place. +This may damage the new filesystem and cause data-loss, just by mounting +it. Because volume_id can not decide which one the correct signature is, +the wrong signatures need to be removed manually from the volume, or the +volume needs to be reformatted, to enable filesystem detection and possible +auto-mounting. + +udev 132 +======== +Fix segfault if compiled without optimization and dbg() does not get +compiled out and uses variables which are not available. + +udev 131 +======== +Bugfixes. (And maybe new bugs. :)) + +The rule matching engine got converted from a rule list to a token +array which reduced the in-memory rules representation of a full +featured distros with thousends of udev rules from 1.2MB to 0.12 MB. +Limits like 5 ENV and ATTR matches, and one single instance for most +other keys per rule are gone. + +The NAME assignment is no longer special cased. If later rules assign +a NAME value again, the former value will be overwritten. As usual +for most other keys, the NAME value can be protected by doing a final +assignment with NAME:="". + +All udev code now uses libudev, which is also exported. The library +is still under development, marked as experimental, and its interface +may change as long as the DeviceKit integration is not finished. + +Many thanks to Alan Jenkins for his continuous help, and finding and +optimizing some of the computing expensive parts. + +udev 130 +======== +Bugfixes. + +Kernel devices and device nodes are connected now by reverse indizes in +/sys and /dev. A device number retrieved by a stat() or similar, the +kernel device directory can be found by looking up: + /sys/dev/{block,char}/: +and the device node of the same device by looking up: + /dev/{block,char}/: + +udev 129 +======== +Fix recently introduced bug, which caused a compilation without large +file support, where vol_id does not recognize raid signatures at the end +of a volume. + +Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links. +Seems some kernel versions prevent the creation of the ieee-* links, +so people used the scsi-* link which disappeared now. + +More libudev work. Almost all udevadm functionality comes from libudev +now. + +udevadm trigger has a new option --type, which allows to trigger events +for "devices", for "subsystems", or "failed" devices. The old option +--retry-failed" still works, but is no longer mentioned in the man page. + udev 128 ======== Bugfixes. @@ -6,9 +103,8 @@ The udevadm info --device-id-of-file= output has changed to use the obvious format.
