test-udev: small fixes * print '\n' on error * use UDEVLIBEXECDIR (udev_rules_new uses it too)

util-lib: move a number of fs operations into fs-util.[ch]

util-lib: split our string related calls from util.[ch] into its own file string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.

everywhere: port everything to sigprocmask_many() and friends This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.

udevd: simplify signal mask handling We used to block all signals, and restore the original signal mask before exec'ing external processes. Now we just block the signals we care about and unconditionally unblock all signals before exec'ing.

udevd: event - port spawn_wait() to sd-event This allows us to drop the special sigterm handling in spawn_wait() as this will now be passed directly to the worker event loop. We now log failing spawend processes at 'warning' level, and timeouts are in terms of CLOCK_BOOTTIME when available, otherwise the behavior is unchanged.

libudev: private - introduce udev_device_new_from_synthetic_event() This allows set_action(), read_uevent_file() and read_db() to be made internal to libudev.

remove unused includes This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.

tmpfiles: add new line type 'v' for creating btrfs subvolumes

udev: support ENV{}=="" global property matches

udev: move global property handling from libudev to udevd

mac: rename apis with mac_{selinux/smack}_ prefix

libudev: util - drop util_delete_path() Use rmdir_parents() from src/shared instead.

udev: timeout - warn after a third of the timeout before killing

udev: never bypass our own logging framework and call vsyslog() directly from udev tools

udev: unify event timeout handling

udev: do not skip the execution of RUN when renaming a network device fails

log: log_error() and friends add a newline after each line anyway, so avoid including it in the log strings

trivial coding style clean ups - Add space between if/for and the opening parentheses - Place the opening brace on same line as the function (not for udev) From the CODING_STYLE Try to use this: void foo() { } instead of this: void foo() { }

Introduce udev object cleanup functions

use streq instead of strcmp

test-udev: include missing.h We need MS_REC and MS_SHARED defined for a proper compilation, so get them from 'missing.h' if not defined already.

udev: move string copy functions to shared/

use the same email address everywhere

udev: fix test

udev: get rid of TEST_PREFIX and use unshare() to fake /sys, /dev, /run

Revert "label: fix systemd-udev labeling of /run directory." This reverts commit 9b5af248f04b6cad8a5bca836e89a39e9f6823d9. Udev now explicitely labels only files/directories in /dev. The selinux array API is not released and will not work on other distros at this moment.

mkdir: append _label to all mkdir() calls that explicitly set the selinux context

label: fix systemd-udev labeling of /run directory. systemd-udev is currently incorrectly labeling /run/udev/* content because it is using selinux prefix labeling of /dev. This patch will allow systemd-udev to use prefix labeling of /dev and /run.

selinux: unify systemd and udev code

udev: replace util_create_path() with mkdir_parents()

udev: remove configuration options for /dev, /sys, /run directories

udev: test - move test/ and src/test/
