If firmware file is not found in the file system, udev
terminates firmware loading. This is not the case if
firmware file exists in the file system but doesn't have
any data in it.

This fixes a build failure with --disable-acl

Changes to rules were introduced by
7c2dee4a4d7f1b264031daaee786a8fe429884e1 while builtin-blkid support was
introduced in other commits. The removal of systemd resulted in this
code causing linker errors. This code adds complexity with no clear
benefit, so we remove it.

Changes to rules were introduced by
06316d9f1a91b4d3efdb7402e72498cb3deb1806 while kmod support was
introduced in other commits. A ton of commits were made involving kmod
and it is quite clear that it is broken, so we remove it.
This changes our rules to depend on modprobe. As long as the modprobe
binary is in /, and not /usr, udev module loading should function
properly.

The structure of the source tree is basically correct and this is
about as far as we can go without hacking at the C code.
|
|
The original Makefile.am was drawn to the top level. This commit
breaks it out into the various directories with SUBDIRS connecting
them. This makes each directory easier to maintain.
|
|
This commit is a first attempt to isolate the udev code from the
remaining code base. It intentionally does not modify any files
but purely delete files which, on a first examination, appear to
not be needed. This is a sweeping commit which may easily have
missed needed code. Files can be retrieved by doing a checkout
from the previous commit:
git checkout 2944f347d0 -- <filename>

If a 'change' event is supposed to remove created symlinks, we create
a new device structure from the sysfs device and fill it with the list
of links, to compute the delta of the old and new list of links to apply.
If the device is already 'remove'd by the kernel though, udev fails to
create the device structure, so the links are not removed properly.

Use udev_device_new() instead of allowing udev_device_new_from_syspath()
to proceed without a sysfs device.

Some keymaps apply to a large range of computer models, not all of which have
all of the scan codes in the maps. If a single scan code is invalid, do not
abort but continue with the next entry in the map. Instead just show the error
message for that particular scan code, to help with debugging.

Commit b1f87c76b1 changed sscanf from %i to %u, as scan codes are unsigned
numbers which can be > 0x7FFFFFFF. However, sscanf doesn't accept hexadecimal
numbers for %u. It works fine with %i, so revert this back.

This was removed ages ago.

According to Linux drivers/input/evdev.c, scan codes are unsigned, not int nor
uint32_t.
Thanks to Dejan Tosovic <dejan@post.com> for reporting this!

The removal of the TIMEOUT= handling in udevd put firmware requests into the
devpath parent/child dependency tracking. Drivers which block in module_init()
asking userspace for firmware ran into a 30 sec device timeout.
The whole firmware loading willl hopefully move into the kernel and
the fragile-since-day-one fake async driver-core device dance involving
udev can be retired:
