Zbigniew Jędrzejewski-Szmek b25a930f0e basic,shared: move a bunch of files to src/shared/
The goal is to move everything that requires selinux or smack
away from src/basic/. This means that src/basic/label.[ch] must move,
which implies btrfs-util.[ch], copy.[ch], and a bunch of other files
which form a cluster of internal use.

This is just moving text around, so there should be no functional difference.

test-blockdev-util is new, because path_is_encrypted() is moved to
blockdev-util.c, and so far we didn't have any tests for code there.

Kay Sievers a095315b3c build-sys: split internal basic/ library from shared/
basic/      can be used by everything
            cannot use anything outside of basic/

libsystemd/ can use basic/
            cannot use shared/

shared/     can use libsystemd/

Let's clean up the naming schemes a bit and use the same one for SMACK
and for SELINUX.

Michal Sekletar 5e78424f4a selinux: fix potential double free crash in child process
Before returning from function we should reset ret to NULL, thus cleanup
function is nop.

Also context_str() returns pointer to a string containing context but not a
copy, hence we must make copy it explicitly.

Michal Sekletar 16115b0a7b socket: introduce SELinuxContextFromNet option
This makes possible to spawn service instances triggered by socket with
MLS/MCS SELinux labels which are created based on information provided by
connected peer.

Implementation of label_get_child_mls_label derived from xinetd.

Łukasz Stelmach 2453d7e447 smack: relabel directories and files created by systemd
Systemd creates directories in /dev. These directories will
get the label of systemd, which is the label of the System
domain, which is not accessable to everyone. Relabel the
directories, files and symlinks created so that they can be
generally used.

Based on a patch by Casey Schaufler <casey@schaufler-ca.com>.

Lennart Poettering 2fa4092c28 util: make time formatting a bit smarter
Instead of outputting "5h 55s 50ms 3us" we'll now output "5h
55.050003s". Also, while outputting the accuracy is configurable.

Basically we now try use "dot notation" for all time values > 1min. For
>= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and
finally 'us'.

This should give reasonably values in most cases.

Lennart Poettering cad45ba11e selinux: rework selinux access check logic
a) Instead of parsing the bus messages inside of selinux-access.c
simply pass everything pre-parsed in the functions

b) implement the access checking with a macro that resolves to nothing
on non-selinux builds

c) split out the selinux checks into their own sources
selinux-util.[ch]

d) this unifies the job creation code behind the D-Bus calls
Manager.StartUnit() and Unit.Start().

Kay Sievers 0f9963a8b8 Revert "label: fix systemd-udev labeling of /run directory."
This reverts commit 9b5af248f0.

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.

Daniel J Walsh 9b5af248f0 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.

Lennart Poettering 5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
