hwdb: Add Thinkpad X1 carbon 3rd gen to 70-pointingstick.hwdb
Like many other recent thinkpads the factory default pointingstick
sensitivity on these devices is quite low, making the pointingstick
very slow in moving the cursor.
This extends the existing hwdb rules for tweaking the sensitivity to
also apply to the X1 carbon 3rd gen model.
cgroup: unify how we invalidate cgroup controller settings
Let's make sure that we follow the same codepaths when adjusting a
cgroup property via the dbus SetProperty() call, and when we execute the
StartupCPUShares= effect.
core: refactor cpu shares/blockio weight cgroup logic
Let's stop using the "unsigned long" type for weights/shares, and let's
just use uint64_t for this, as that's what we expose on the bus.
Unify parsers, and always validate the range for these fields.
Correct the default blockio weight to 500, since that's what the kernel
actually uses.
When parsing the weight/shares settings from unit files accept the empty
string as a way to reset the weight/shares value. When getting it via
the bus, uniformly map (uint64_t) -1 to unset.
Open up StartupCPUShares= and StartupBlockIOWeight= to transient units.
core: add support for the "pids" cgroup controller
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.
tree-wide: never use the off_t unless glibc makes us use it
off_t is a really weird type as it is usually 64bit these days (at least
in sane programs), but could theoretically be 32bit. We don't support
off_t as 32bit builds though, but still constantly deal with safely
converting from off_t to other types and back for no point.
Hence, never use the type anymore. Always use uint64_t instead. This has
various benefits, including that we can expose these values directly as
D-Bus properties, and also that the values parse the same in all cases.
smack: label /etc/mtab as "_" when '--with-smack-run-label' is enabled.
/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.

logind: allow dry run variants for scheduled shutdowns
Allow passing a "dry-" prefix to the action parameter passed to
.ScheduleShutdown(). When strings with this prefix are passed,
the scheduled action will not take place. Instead, an info message
is logged.

locale: kill free_and_replace()
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.
tree-wide: make use of log_error_errno() return value in more cases
The previous coccinelle semantic patch that improved usage of
log_error_errno()'s return value, only looked for log_error_errno()
invocations with a single parameter after the error parameter. Update
the patch to handle arbitrary numbers of additional arguments.

core: freeze execution if /etc/mtab exists
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.
smack: bugfix the smack label of symlink when '--with-smack-run-label' is set
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.

gpt-auto: fix ESP options and description
Since 59512f21 the parameters were passed in the wrong order, causing the
options to be interpreted as the description.
Also, while "false" was supposed to be passed for "rw", the ESP should actually
be mounted read-write. It just happened to be "true" since the description char*
was passed for "rw".
