selinux: fix regression of systemctl subcommands when absolute unit file paths are specified

The commit 4938696301a914ec26bcfc60bb99a1e9624e3789 overlooked the
fact that unit files can be specified as unit file paths, not unit
file names, wrongly passing a unit file path to the 1st argument of
manager_load_unit() that handles it as a unit file name. As a result,
the following 4 systemctl subcommands:

    enable
    disable
    reenable
    link
    mask
    unmask

fail with the following error message:

    # systemctl enable /usr/lib/systemd/system/kdump.service
    Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.

    Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.

To fix the issue, first check whether a unit file is passed as a unit
file name or a unit file path, and then pass the unit file to the
appropreate argument of manager_load_unit().

By the way, even with this commit mask and unmask reject unit file
paths as follows and this is a correct behavior:

    # systemctl mask /usr/lib/systemd/system/kdump.service

    # systemctl unmask /usr/lib/systemd/system/kdump.service

sd-device: fix enumeration of devices without subsystem

Prior to commit c32eb440bab953a0169cd207dfef5cad16dfb340, libudev's
function udev_enumerate_scan_devices() had behaved differently. If
parent match was added with udev_enumerate_add_match_parent(),
udev_enumerate_scan_devices() did not return error if some child devices
had no subsystem symlink in sysfs. An example of such devices is USB
endpoints /sys/bus/usb/devices/*/ep_*. If there was a parent match
against USB device, old implementation of udev_enumerate_scan_devices()
did not treat ep_* device directories without subsystem symlink as error
and just ignored them, but new implementation returns -ENOENT (also
ignoring these devices) though correctly enumerates all other matching
devices.

To compare, you could look at 96df036fe3d25525a44f5efdb2fc8560e82e6cfd,
in src/libudev/libudev-enumerate.c, function parent_add_child():

    if (!match_subsystem(enumerate, udev_device_get_subsystem(dev)))
            goto nomatch;

udev_device_get_subsystem() was returning NULL, match_subsystem() was
returning false, and USB endpoint device was ignored.

New parent_add_child() from src/libsystemd/sd-device/device-enumerator.c
checks return value of sd_device_get_subsystem() and fails if subsystem
was not found. Absence of subsystem symlink should not be really treated
as error because all enumerations of children of USB devices will fail
with -ENOENT. This new behavior also breaks system-config-printer.

So restore old behavior and treat absence of subsystem symlink as no
match.

nss-myhostname already implemented.

Local hostnames resolve to the set of local IP addresses. Since the

per-reply. This change also patches  the existing clients for resolved
accordingly (nss-resolve + systemd-resolve-host).

that the local hostname is never resolved via LLMNR, thus making it
trustable on the local system.
