2015-09-10core: add support for the "pids" cgroup controllerLennart Poettering
This adds support for the new "pids" cgroup controller of 4.3 kernels. It allows accounting the number of tasks in a cgroup and enforcing limits on it. This adds two new setting TasksAccounting= and TasksMax= to each unit, as well as a gloabl option DefaultTasksAccounting=. This also updated "cgtop" to optionally make use of the new kernel-provided accounting. systemctl has been updated to show the number of tasks for each service if it is available. This patch also adds correct support for undoing memory limits for units using a MemoryLimit=infinity syntax. We do the same for TasksMax= now and hence keep things in sync here.

2015-09-10smack: label /etc/mtab as "_" when '--with-smack-run-label' is enabled.Sangjung Woo
/etc/mtab should be labeled as "_", even though systemd has its own smack label using '--with-smack-run-label' configuration. This is mainly because all processes could read that file and the origin of this file (i.e. /proc/mounts) is labeled as "_". This labels /etc/mtab as "_" when '--with-smack-run-label' is enabled.

2015-09-09locale: kill free_and_replace()Daniel Mack
That function really makes little sense, as the open-coded variant is much more readable. Also, if the 2nd argument is NULL, mfree() is a much better candidate. Convert the only users of this function in localed, and then remove it entirely.

Wrong smack label of the symlink in CGROUP root directory when enabling '--with-smack-run-label' (v3)
2015-09-09core: freeze execution if /etc/mtab existsDaniel Mack
The mount monitor that was added to libmount v2.27 requires /etc/mtab to be non-existant. As systemd now uses that functionality, we cannot monitor any mounts anymore, and hence not support .mount units. Systems that have /etc/mtab around as regular file are unsupported by systemd since a long time. This patch makes that condition fatal, so we do not boot up with non-working mount monitor support.

2015-09-09smack: bugfix the smack label of symlink when '--with-smack-run-label' is setSangjung Woo
Even though systemd has its own smack label since '--with-smack-run-label' configuration is set, the smack label of each CGROUP root directory should have the star (i.e. *) label. This is mainly because current Linux Kernel set the label in this way. (Refer to smack_d_instantiate() in security/smack/smack_lsm.c) However, if systemd has its own smack label and arg_join_controllers is explicitly set or initialized by initialize_join_controllers() function, current systemd creates the symlink in CGROUP root directory with its own smack label as below. lrwxrwxrwx. 1 root root System 11 Dec 31 16:00 cpu -> cpu,cpuacct dr-xr-xr-x. 4 root root * 0 Dec 31 16:01 cpu,cpuacct lrwxrwxrwx. 1 root root System 11 Dec 31 16:00 cpuacct -> cpu,cpuacct This patch fixes that bug by copying the smack label from the origin.

This adds a new mac_smack_copy() function in order to read the smack label from the source and apply it to the destination.
