2015-07-29tree-wide: port everything over to fflush_and_check()Lennart Poettering
Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
2015-07-09nss-mymachines: map userns users of containers to real user namesLennart Poettering
Given a container "foo", that maps user id $UID to container user, using user namespaces, this NSS module extenstion will now map the $UID to a name "vu-foo-$TUID" for the translated UID $UID. Similar, userns groups are mapped to "vg-foo-$TGID" for translated GIDs of $GID. This simple change should make userns users more discoverable. Also, given that many tools like "adduser" check NSS before allocating a UID, should lower the chance of UID range conflicts between tools.

2015-07-08property callback returns are consistentUmut Tezduyar Lindskog
It is no different to return 0 over 1 in the property callback. It is confusing to return 1 which made me think 1 has a special purpose. This way code is consistent with the rest of the tree.
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327
2015-06-17turn kdbus support into a runtime optionKay Sievers
./configure --enable/disable-kdbus can be used to set the default behavior regarding kdbus. If no kdbus kernel support is available, dbus-dameon will be used. With --enable-kdbus, the kernel command line option "kdbus=0" can be used to disable kdbus. With --disable-kdbus, the kernel command line option "kdbus=1" is required to enable kdbus support.
2015-06-17Stop talking about the "XDG" version of basename()Simon McVittie
XDG refers to X Desktop Group, a former name for freedesktop.org. This group is responsible for specifications like basedirs, .desktop files and icon naming, but as far as I know, it has never tried to redefine basename(). I think these references were meant to say XPG (X/Open Portability Guide), a precursor of POSIX. POSIX is better-known and less easily confused with XDG, and is how the basename(3) man page describes the libgen.h version of basename(). The other version of basename() is glibc-specific and is described in basename(3) as "the GNU version"; specifically mention that version, to disambiguate.
2015-06-15everywhere: port everything to sigprocmask_many() and friendsLennart Poettering
This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.
2015-06-14tree-wide: fix memory leaks in users of bus_map_all_properties()David Herrmann
If you use bus_map_all_properties(), you must be aware that it might touch output variables even though it may fail. This is, because we parse many different bus-properties and cannot tell how to clean them up, in case we fail deep down in the parser. Fix all callers of bus_map_all_properties() to correctly cleanup any context structures at all times.

2015-05-05core: rework unit name validation and manipulation logicLennart Poettering
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
2015-04-29sd-bus: allow passing NULL as bus parameter to sd_bus_send()Lennart Poettering
If NULL is specified for the bus it is now automatically derived from the passed in message. This commit also changes a number of invocations of sd_bus_send() to make use of this.
2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().

2015-04-28machined: make sure to track machine unit states properlyLennart Poettering
If a unit is stopped for a moment, we need to invalidate our knowledge of it, otherwise we might be confused by automatic restarts This makes reboots for nspawn containers run as service work correctly. https://bugs.freedesktop.org/show_bug.cgi?id=87428

2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-10shared: the btrfs quota field is called "referenced" not "referred"Lennart Poettering

2015-03-09importd: add API for exporting container/VM imagesLennart Poettering
Also, expose it in machinectl.
2015-03-07machine: do not rely on asprintf setting arg on errorZbigniew Jędrzejewski-Szmek
Strictly speaking, the output variable is undefined if asprintf fails. We use the return value not the arg everywhere, and should we do here.
2015-03-05machinectl: minor --help text improvementsLennart Poettering
2015-03-05importd: add new bus calls for importing local tar and raw imagesLennart Poettering
This also adds "machinectl import-raw" and "machinectl import-tar" to wrap these new bus calls. THe commands basically do for local files that "machinectl pull-raw" and friends do for remote files.
2015-03-03importd: automatically grow /var/lib/machines/ loopback filesystem during ↵Lennart Poettering
downloads If /var/lib/machines is mounted as btrfs loopback file system in /var/lib/machines.raw with this change we automatically grow the file system as it fills up. After each 10M we write to it during imports, we check the free disk space, and if the fill level grows beyond 66% we increase the size of the file system to 3x the fill level (thus lowering it to 33%).

pool size
2015-03-01machined: use x-machine-unix prefix for the container bus on dbus1Benjamin Franzke
This fixes "machinectl login" on systems configured with --disable-kdbus. The error was: machinectl login foo Failed to get machine PTY: Input/output error
2015-02-26machined: if /var/lib/machines is backed by a loop file, resize it on ↵Lennart Poettering
"machinectl set-limit" When the pool size limit is altered with "machinectl set-limit", then not only set the subvolume quota of the /var/lib/machine subvolume, but also resize the backing loop file and the btrfs file system on it dynamically.

2015-02-24machined: actually open up methods to unprivileged clients on dbus1Lennart Poettering
Many of machined's operations are now opened up to unprivileged clients via PolicyKit. Open up the dbus policy so that we can actually make these calls. kdbus doesn't reuqire this, hence this wasn't noticed before.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-18nspawn: when connected to pipes for stdin/stdout, pass them as-is to PID 1Lennart Poettering
Previously we always invoked the container PID 1 on /dev/console of the container. With this change we do so only if nspawn was invoked interactively (i.e. its stdin/stdout was connected to a TTY). In all other cases we directly pass through the fds unmodified. This has the benefit that nspawn can be added into shell pipelines. https://bugs.freedesktop.org/show_bug.cgi?id=87732
2015-02-18logind: open up most bus calls for unpriviliged processes, using PolicyKitLennart Poettering
Also, allow clients to alter their own objects without any further priviliges. i.e. this allows clients to kill and lock their own sessions without involving PK.

2015-02-17machined: move logic for bind mounting into containers from machinectl to ↵Lennart Poettering
machined This extends the bus interface, adding BindMountMachine() for bind mounting directories from the host into the container.
2015-02-12Revert "tree-wide: Always use recvmsg with MSG_CMSG_CLOEXEC"Lennart Poettering
This reverts commit d6d810fbf8071f8510450dbacd1d083f37603656. It's apparently not OK to pass MSG_CMSG_CLOEXEC to recvmsg() of raw sockets.
2015-02-11tree-wide: whenever we include libgen.h, immediately undefine basename()Lennart Poettering
Also, document in adjacent comments and in CODING_STYLE why we do that.

2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
