Subject: [PATCH] resolved: Move symlink creation from tmpfiles to daemon
runtime
At least Fedora right now doesn't by default use resolved; the service
is disabled by default in the 90-default.preset file.
The change to unconditionally create the resolv.conf symlink broke
Anaconda and related tools (lorax) which expect it to be a regular
file. In particular, Anaconda expects to be able to persist
networking state from the installation environment to the target
system.

Subject: [PATCH] systemctl: fail in the case that no unit files were found
Previously systemctl died with message
-bash-4.2# systemctl --root /rawhi list-unit-files
(src/systemctl/systemctl.c:868) Out of memory.
in the case that no unit files were found in the --root
or the directory did not exist.
So lets return ENOENT in the case that --root does not exist
and empty list in the case that there are no unit files.

Subject: [PATCH] journalctl: add "-t --identifier=STRING" option
This turns journalctl to the counterpart of systemd-cat.
Messages sent with
systemd-cat --identifier foo --prioritiy debug
can now be shown with
journalctl --identifier foo --prioritiy debug
"--identifier" is not merged with "--unit" to make a clear
distinction between syslog and systemd units.
syslog identifiers can be chosen freely by anyone.

Subject: [PATCH] util: change return value of startswith() to non-const
This way we can use it on non-const strings, and don't end up with a
const'ified result.
This is similar to libc's strstr() which also takes a const string but
returns a non-const one.

Subject: [PATCH] service,strv: introduce strv_find_startswith() and make use
of it
Unlike strv_find_prefix() the new call will return a pointer to the
suffix of the item we found, instead of the whole item. This is more
closer inline with what startswith() does, and allows us to simplify a
couple of invocations.

Subject: [PATCH] bus: when terminating our bus-actviated services that
exit-on-idle send STOPPING=1 via sd_notify()
This should fix a race where a service thatis idle drops its name, and
is immediately requested by another client, which causes dbus-daemon to
ask systemd to activate it again, but since systemd still assumes it is
running it won't do anything.

Subject: [PATCH] shared: add MAXSIZE() and use it in resolved
The MAXSIZE() macro takes two types and returns the size of the larger
one. It is much simpler to use than MAX(sizeof(A), sizeof(B)) and also
avoids any compiler-extensions, unlike CONST_MAX() and MAX() (which are
needed to avoid evaluating arguments more than once). This was suggested
by Daniele Nicolodi <daniele@grinta.net>.
Also make resolved use this macro instead of CONST_MAX(). This enhances
readability quite a bit.

Subject: [PATCH] core: add support for a configurable system-wide start-up
timeout
When this system-wide start-up timeout is hit we execute one of the
failure actions already implemented for services that fail.
This should not only be useful on embedded devices, but also on laptops
which have the power-button reachable when the lid is closed. This
devices, when in a backpack might get powered on by accident due to the
easily reachable power button. We want to make sure that the system
turns itself off if it starts up due this after a while.
When the system manages to fully start-up logind will suspend the
machine by default if the lid is closed. However, in some cases we don't
even get as far as logind, and the boot hangs much earlier, for example
because we ask for a LUKS password that nobody ever enters.
Yeah, this is a real-life problem on my Yoga 13, which has one of those
easily accessible power buttons, even if the device is closed.

Subject: [PATCH] core: split up "starting" manager state into "initializing"
and "starting"
We'll stay in "initializing" until basic.target has reached, at which
point we will enter "starting".
This is preparation so that we can change the startip timeout to only
apply to the first phase of startup, not the full procedure.

Subject: [PATCH] systemctl: fix broken list-unit-files with --root
This patch modifies unit_file_get_list which will now return
hashmap of structures where f->path is *without* root_dir prefix.
This change should be ok, because current code either does not use
root_dir at all or calls basename() on the f->path.

Subject: [PATCH] sd-event: split run into prepare/wait/dispatch
This will allow sd-event to be integrated into an external event loop, which
in turn will allow (say) glib-based applications to use our various libraries,
without manually integrating each of them (bus, rtnl, dhcp, ...).
The external event-loop should integrate sd-event int he following way:
Every iteration must start with a call to sd_event_prepare(), which will
return 0 if no event sources are ready to be processed, a positive value if
they are and a negative value on error. sd_event_prepare() may only be called
following sd_event_dispatch(); a call to sd_event_wait() indicating that no
sources are ready to be dispatched; or a failed call to sd_event_dispatch() or
sd_event_wait().
A successful call to sd_event_prepare() indicating that no event sources are
ready to be dispatched must be followed by a call to sd_event_wait(),
which will return 0 if it timed out without event sources being ready to
be processed, a negative value on error and a positive value otherwise.
sd_event_wait() may only be called following a successful call to
sd_event_prepare() indicating that no event sources are ready to be dispatched.
If sd_event_wait() indicates that some events sources are ready to be
dispatched, it must be followed by a call to sd_event_dispatch(). This
is the only time sd_event_dispatch() may be called.

This reverts commit 41a451cc2901a5deb985aea4cc8de204a22e5612.
This breaks checks for masking of units file, since we invoke
null_or_empty_path() on the resulting path.

Subject: [PATCH] util: reset signals when we fork off agents
If we invoke agents, we should make sure we actually can kill them
again. I mean, it's probably not our job to cleanup the signals if our
tools are invoked in weird contexts, but at least we should make sure,
that the subprocesses we invoke and intend to control work as intended.

Subject: [PATCH] units: order systemd-fsck@.service after local-fs-pre.target.
With this change, it becomes possible to order a unit to activate before any
modifications to the file systems. This is especially useful for supporting
resume from hibernation.

Subject: [PATCH] hibernate-resume: add a tool to write a device node's
major:minor to /sys/power/resume.
This can be used to initiate a resume from hibernation by path to a swap
device containing the hibernation image.
The respective templated unit is also added. It is instantiated using
path to the desired resume device.

From d2c68822c47e37b582820f45b496b2e7d1f9e642 Mon Sep 17 00:00:00 2001
From: Ivan Shapovalov <intelfx100@gmail.com>
Date: Wed, 27 Aug 2014 00:17:45 +0400
Subject: [PATCH] hibernate-resume-generator: add a generator for instantiating
the resume unit.
hibernate-resume-generator understands resume= kernel command line parameter
and instantiates the systemd-resume@.service accordingly if it is passed.
This enables resume from hibernation using device specified on the kernel
command line, and it may be specified either as "/dev/disk/by-foo/bar"
or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel
implementation.
So now resume= is brought on par with root= in terms of possible ways to
specify a device.

Subject: [PATCH] shared: drop UNIQUE()
The UNIQUE() macro works fine if used in un-stacked macros. However, once
you stack them like:
MAX(MIN(a, b),
CLAMP(MAX(c, d), e, f))
you will get warnings due to shadowing other variables. gcc uses the last
line of a macro expansion as value for __LINE__, therefore, we cannot even
avoid this by splitting the expressions across lines.
Remove the only user of UNIQUE() so we introduce a new helper in
follow-ups.

Subject: [PATCH] shared: make container_of() use unique variable names
If you stack container_of() macros, you will get warnings due to shadowing
variables of the parent context. To avoid this, use unique names for
variables.
Two new helpers are added:
UNIQ: This evaluates to a truly unique value never returned by any
evaluation of this macro. It's a shortcut for __COUNTER__.
UNIQ_T: Takes two arguments and concatenates them. It is a shortcut for
CONCATENATE, but meant to defined typed local variables.
As you usually want to use variables that you just defined, you need to
reference the same unique value at least two times. However, UNIQ returns
a new value on each evaluation, therefore, you have to pass the unique
values into the macro like this:
#define my_macro(a, b) __max_macro(UNIQ, UNIQ, (a), (b))
#define __my_macro(uniqa, uniqb, a, b) ({
typeof(a) UNIQ_T(A, uniqa) = (a);
typeof(b) UNIQ_T(B, uniqb) = (b);
MY_UNSAFE_MACRO(UNIQ_T(A, uniqa), UNIQ_T(B, uniqb));
})
This way, MY_UNSAFE_MACRO() can safely evaluate it's arguments multiple
times as they are local variables. But you can also stack invocations to
the macro my_macro() without clashing names.
This is the same as if you did:
#define my_macro(a, b) __max_macro(__COUNTER__, __COUNTER__, (a), (b))
#define __my_macro(prefixa, prefixb, a, b) ({
typeof(a) CONCATENATE(A, prefixa) = (a);
typeof(b) CONCATENATE(B, prefixb) = (b);
MY_UNSAFE_MACRO(CONCATENATE(A, prefixa), CONCATENATE(B, prefixb));
})
...but in my opinion, the first macro is easier to write and read.
This patch starts by converting container_of() to use this new helper.
Other macros may follow (like MIN, MAX, CLAMP, ...).

Our bus-name watch helpers only remove a bus-name if it's not a
controller, anymore. If we call manager_drop_busname() before
unregistering the controller, the busname will not be dropped. Therefore,
first drop the controller, then drop the bus-name.

Subject: [PATCH] bus: split bus_map_all_properties into multiple helpers
The bus_map_all_properties() helper calls
org.freedesktop.DBus.Properties.GetAll() on a given target and parses the
result according to a given property-table. This simplifies dealing with
DBus.Properties significantly. However, the function is blocking and thus
not really useful in many situations.
This patch extracts the core of this function and adds two new helpers
which directly take dbus-messages as arguments. This way, you can issue
asynchronous requests and parse the result via these helpers:
bus_message_map_all_properties():
This is the same as bus_map_all_properties() but takes the result
message from a GetAll() request as argument. You can thus issue an
asynchronous GetAll() request and then use this helper once you got
the result.
bus_message_map_properties_changed():
This function takes a signal-message that was retrieved via a
PropertiesChanged signal and then parses it like if you retrieved
it via GetAll(). Furthermore, this function returns the number of
matched properties that got invalidated by the PropertiesChanged
signal, but didn't carry the new value. This way, the caller can
issue a new GetAll() request and then parse the result.
The old function bus_map_all_properties() is functionally unchanged, but
now uses bus_message_map_all_properties() internally.

Subject: [PATCH] terminal: add input interface
The idev-interface provides input drivers for all libsystemd-terminal
based applications. It is split into 4 main objects:
idev_context: The context object tracks global state of the input
interface. This will include data like system-keymaps,
xkb contexts and more.
idev_session: A session serves as controller for a set of devices.
Each session on an idev-context is independent of each
other. The session is also the main notification object.
All events raised via idev are reported through the
session interface. Apart of that, the session is a
pretty dumb object that just contains devices.
idev_element: Elements provide real hardware in the idev stack. For
each hardware device, one element is added. Elements
have no knowledge of higher-level device types, they
only provide raw input data to the upper levels. For
example, each evdev device is represented by a different
element in an idev session.
idev_device: Devices are objects that the application deals with. An
application is usually not interested in elements (and
those are hidden to applications), instead, they want
high-level input devices like keyboard, touchpads, mice
and more. Device are the high-level interface provided
by idev. Each device might be fed by a set of elements.
Elements drive the device. If elements are removed,
devices are destroyed. If elements are added, suitable
devices are created.
Applications should monitor the system for sessions and hardware devices.
For each session they want to operate on, they create an idev_session
object and add hardware to that object. The idev interface requires the
application to monitor the system (preferably via sysview_*, but not
required) for hardware devices. Whenever hardware is added to the idev
session, new devices *might* be created. The relationship between hardware
and high-level idev-devices is hidden in the idev-session and not exposed.
Internally, the idev elements and devices are virtual objects. Each real
hardware and device type inherits those virtual objects and provides real
elements and devices. Those types will be added in follow-up commits.
Data flow from hardware to the application is done via idev_*_feed()
functions. Data flow from applications to hardware is done via
idev_*_feedback() functions. Feedback is usually used for LEDs, FF and
similar operations.

Subject: [PATCH] terminal: add systemd-evcat input debugging tool
Like systemd-subterm, this new systemd-evcat tool should only be used to
debug libsystemd-terminal. systemd-evcat attaches to the running session
and pushes all evdev devices attached to the current session into an
idev-session. All events of the created idev-devices are then printed to
stdout for input-event debugging.

Before forking, block all signals, and unblock them afterwards. This way

Subject: [PATCH] terminal: sysview: don't return uninitialized error codes
In case 'scan_evdev' and 'scan_drm' are both false, we never set 'r' to
anyhting, thus return an uninitialized error code. Fix this by always
returning 0 as we catch negative codes earlier, anyway. Thanks to Thomas
H.P. Anderson for the report.

Subject: [PATCH] terminal: free sysview-device names on destruction
Don't leak the device-names during device destruction in sysview. Somehow,
the device-name is "const char*", so make it "char*" first to avoid
warnings when calling free() on it.

Subject: [PATCH] bus: fix use-after-free in slot-release
We must not access slot->floating after we possible dropped the last
reference to it. Fix all callback-invocations to first check
slot->floating and possible disconnect the slot, then release the last
reference.

Subject: [PATCH] macro: use unique variable names for math-macros
Similar to container_of(), we now use unique variable names for the bascic
math macros MAX, MIN, CLAMP, LESS_BY. Furthermore, unit tests are added to
verify they work as expected.
For a rationale, see:
