${rootlibdir}/udev instead of ${root}/lib/udev

This adds /lib if split-usr is enabled
to the directories where udev searches for rules.d.
This is needed if split-usr is enabled because some software still
installs rules in /lib/udev/rules.d.

It is possible for udev_hwdb_get_properties_list_entry to be invoked
during udevd initialization before hwdb has been initialized. We
workaround that for now by introducing a check to handle that.

This commit reintroduces code to
1) build src/keymap
2) test keymap/Makefile.am that it has all the key maps listed
3) test that all the key names in keymap/* are in <linux/input.h>
4) do a syntax check on rules/*.rules which now includes
95-keymap.rules and 95-keyboard-force-release.rules
For #4, the regex expressions in rule-syntax-check.py had to be
updated. They do not allow trailing comments via # comment, and
I did not include that. A rule in 95-keymap.rules had to have its
comment moved from the end to another line.

A last minute change to commit 189d09a42e054bebd91ea9690fede33b41996260
caused a build failure. This fixes it.

unshare() is a linux syscall that we need. Unfortunately, access to it
depends on __GNU_SOURCE, which we would like to avoid. As such, we
define a macro to invoke it by its syscall code. This is necessary to
avoid the following warning from Clang:
implicit declaration of function 'unshare' is invalid in C99
[-Wimplicit-function-declaration]

Clang 3.1 indicated that we had implicitly declared several, which is
illegal in C99.

Clang 3.1 warned that "attribute 'packed' is ignored". This stems from
placing "__attribute__ ((packed))" at the start of structure
declarations when common practice is to place it at the end.

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.

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>

The point is to allow the use of journald functions by other binaries.
Before, journald code was split into multiple files (journald-*.[ch]),
but all those files all required functions from journald.c. And
journald.c has its own main(). Now, it is possible to link against
those functions, e.g. from test binaries.
This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638.
The patch does the following:
1. rename journald.h to journald-server.h and move corresponding code
to journald-server.c.
2. add journald-server.c and other journald-*.c parts to
libsystemd-journal-internal.
3. remove journald-syslog.c from test_journal_syslog_SOURCES, since
it is now contained in libsystemd-journal-internal.
There are no code changes, apart from the removal of a few static's,
to allow function calls between files.

Both the help and man page claims that it accepts -t with an argument
so let's do that.

Supports Python versions 2.6 through 3.3 (tested on 2.7 and 3.2).
See JournalHandler docstring for usage details.
[zj: - use send() instead of using sendv() directly
- do exception handling like in the logging module
- bumped min version to python2.6, since the module
does not work with python2.5 anyway ]
|
|
Makes the output way nicer with shorter code. Also brings
systemd-analyze behaviour more in line with other systemd-programs.
Argparse is in Python since 2.6, and is available as a package for
previous versions, if someone is stuck with very old Python.

The warning was invalid, but distracting.

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.
