Here comes a new udev version. Thanks to all who have contributed to this release. The tarball can be found here: ftp://ftp.kernel.org/pub/linux/utils/kernel/hotplug/ The development repository can be found here: http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=summary The ChangeLog can be found here: http://www.kernel.org/git/?p=linux/hotplug/udev.git;a=blob;hb=HEAD;f=ChangeLog udev 133 ======== Bugfix for kernels using the SYSFS_DEPRECATED* option and finding parent block devices in some cases. 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 thousands 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:="<value>". 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. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
