udev 098
========
Bugfixes.
Renaming of some key names (the old names still work):
BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
(The behavior of the key DRIVER will change soon in one of the next
releases, to match only the event device, please switch to DRIVERS
instead. If DRIVER is used, it will behave like DRIVERS, but an error
is logged.
With the new key names, we have a more consistent and simpler scheme.
We can match the properties of the event device only, with: KERNEL,
SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
longer mentioned in the man page and should be switched in the rule
files.
ATTR{file}="value" can be used now, to write to a sysfs file of the
event device. Instead of:
..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
we now can do:
..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
All the PHYSDEV* keys are deprecated and will be removed from a
future kernel:
PHYDEVPATH - is the path of a parent device and should not be
needed at all.
PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
matched with SUBSYSTEMS==
PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
Newer kernels will have DRIVER in the environment,
for older kernels udev puts in. Class device will
no longer carry this property of a parent and
DRIVERS== can be used to match such a parent value.
Note that ENV{DRIVER} is only available for a few bus devices, where
the driver is already bound at device event time. On coldplug, the
events for a lot devices are already bound to a driver, and they will have
that value set. But on hotplug, at the time the kernel creates the device,
it can't know what driver may claim the device after that, therefore
in most cases it will be empty.
Failed events should now be re-triggered with:
udevtrigger --retry-failed.
Please switch to this command, so we keep the details of the /dev/.udev/failed/
files private to the udev tools. We may need to switch the current symlink
target, cause some obviously broken tools try to scan all files in /dev
including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
million times. This takes ages on slow boxes.
The udevinfo attribute walk (-a) now works with giving a device node
name (-n) instead of a devpath (-p). The query now always works, also when
no database file was created by udev.
The built-in /etc/passwd /etc/group parser is removed, we always depend on
getpwnam() and getgrnam() now. One of the next releases will depend on
fnmatch() and may use getopt_long().

========

%e is finally gone.
Added support for swapping network interface names, by temporarily
renaming the device and wait for the target name to become free.

These things need to be done, or would be nice to have:
o Log the relationship of the kernel name and the persistent disk name
These things would be nice to have:
o log the relationship of the kernel name and the persistent disk name
to syslog, so any error logged from the kernel can be associated with
any of the links at that time.
any of the links at that time
These things will change in future udev versions:
o remove /sys prefix from symlinks in /dev/.udev/{queue,failed}
(broken tools search /dev for files and get lost following to /sys
and stat() sysfs files million times)
o make DRIVER== to match only the event device
(DRIVERS must be used, we currently translate it to DRIVERS and print
an error if DRIVER is used)
o switch to fnmatch() instead of our own implementation
o warn if PHYSDEV* keys are used in ENV keys
(they are deprecated and will be removed from a future kernel)
o warn if "/device/" is used in a ATTR, ATTRS, $sysfs key
(the device link must not be used in rules or tools, udev resolves
the link and makes the devices available as parents, which can
be matched with the normal keys)
o warn if BUS, ID, SYSFS are used as keys
(they are SUBSYSTEMS, KERNELS, ATTRS now)
These things are deprecated and scheduled for removal in a future
udev version:
o remove old udevdb dump 'udevinfo -d'
(-e exports everything)
o remove udevstart
(we rely on the kernel "uevent" triggers of kernel 2.6.15 and no longer
want to guess event properties from sysfs like udevstart is doing it)
o remove extra for /etc/dev.d/ /etc/hotplug.d/
(that inefficient stuff should finally go away)
