2016-09-13fileio: simplify mkostemp_safe() (#4090)Topi Miettinen
According to its manual page, flags given to mkostemp(3) shouldn't include O_RDWR, O_CREAT or O_EXCL flags as these are always included. Beyond those, the only flag that all callers (except a few tests where it probably doesn't matter) use is O_CLOEXEC, so set that unconditionally.
2016-09-10shared/install: fix set-default with empty root (#4118)Zbigniew Jędrzejewski-Szmek
https://bugzilla.redhat.com/show_bug.cgi?id=1374371 When root was empty or equal to "/", chroot_symlinks_same was called with root==NULL, and strjoina returned "", so the code thought both paths are equal even if they were not. Fix that by always providing a non-null first argument to strjoina.

Previous fix didn't consider handling multiple ExecStop commands.
2016-09-09shared: recognize DNS names with more than one trailing dot as invalid (#4111)Martin Pitt
One trailing dot is valid, but more than one isn't. This also fixes glibc's posix/tst-getaddrinfo5 test. Fixes #3978.
2016-09-09unit: sent change signal before removing the unit if necessary (#4106)Michael Olbrich
If the unit is in the dbus queue when it is removed then the last change signal is never sent. Fix this by checking the dbus queue and explicitly send the change signal before sending the remove signal.

2016-09-09service: Continue shutdown on socket activated unit on termination (#4108)Kyle Russell
ENOTCONN may be a legitimate return code if the endpoint disappeared, but the service should still attempt to shutdown cleanly.
2016-09-06nspawn: detect SECCOMP availability, skip audit filter if unavailableFelipe Sateler
Fail hard if SECCOMP was detected but could not be installed
2016-09-06seccomp: also detect if seccomp filtering is enabledFelipe Sateler
In https://github.com/systemd/systemd/pull/4004 , a runtime detection method for seccomp was added. However, it does not detect the case where CONFIG_SECCOMP=y but CONFIG_SECCOMP_FILTER=n. This is possible if the architecture does not support filtering yet. Add a check for that case too. While at it, change get_proc_field usage to use PR_GET_SECCOMP prctl, as that should save a few system calls and (unnecessary) allocations. Previously, reading of /proc/self/stat was done as recommended by prctl(2) as safer. However, given that we need to do the prctl call anyway, lets skip opening, reading and parsing the file. Code for checking inspired by https://outflux.net/teach-seccomp/autodetect.html

2016-09-01systemctl: usable status command for special units (#4072)Cireo
Prior to this commit, users could be given an unusable command to run if they attempted to stop or start special services. For example: $ systemctl stop -- -.mount Failed to stop -.mount: Operation refused, unit -.mount may be \ requested by dependency only. See system logs and 'systemctl status -.mount' for details. $ systemctl status -.mount systemctl: invalid option -- '.' This adds a '--' to the example command in these situations.

2016-08-31machinectl: split OS field in two; print ip addresses (#4058)Seraphime Kirkovski
This splits the OS field in two : one for the distribution name and one for the the version id. Dashes are written for missing fields. This also prints ip addresses of known machines. The `--max-addresses` option specifies how much ip addresses we want to see. The default is 1. When more than one address is written for a machine, a `,` follows it. If there are more ips than `--max-addresses`, `...` follows the last address.

2016-08-30bootctl: properly skip duplicate entries (#4048)Mantas Mikulėnas
'continue' is a fancy no-op here – it only skips through the inner loop, not the outer one, so entries already in BootOrder get printed twice. This partially reverts f939cff71577 "bootctl: various coding style updates".

2016-08-29basic/fileio: we always have O_TMPFILE nowYann E. MORIN
fileio makes use of O_TMPFILE when it is available. We now always have O_TMPFILE, defined in missing.h if missing from the toolchain headers. Have fileio include missing.h and drop the guards around the use of O_TMPFILE.
2016-08-29missing.h: add missing definitions for __O_TMPFILEYann E. MORIN
Currently, a missing __O_TMPFILE was only defined for i386 and x86_64, leaving any other architectures with an "old" toolchain fail miserably at build time: src/import/export-raw.c: In function 'reflink_snapshot': src/import/export-raw.c:271:26: error: 'O_TMPFILE' undeclared (first use in this function) new_fd = open(d, O_TMPFILE|O_CLOEXEC|O_NOCTTY|O_RDWR, 0600); ^ __O_TMPFILE (and O_TMPFILE) are available since glibc 2.19. However, a lot of existing toolchains are still using glibc-2.18, and some even before that, and it is not really possible to update those toolchains. Instead of defining it only for i386 and x86_64, define __O_TMPFILE with the specific values for those archs where it is different from the generic value. Use the values as found in the Linux kernel (v4.8-rc3, current as of time of commit). --- Note: tested on ARM (build+run), with glibc-2.18 and linux headers 3.12. Untested on other archs, though (I have no board to test this). Changes v1 -> v2: - add a comment specifying some are hexa, others are octal.
2016-08-29importd/export-raw: needs missing.h for O_TMPFILEYann E. MORIN
O_TMPFILE may be missing from the system headers, so use our fallback definition. --- Changes v1 -> v2: - move include with local includes

2016-08-26nspawn: split down SYSTEMD_NSPAWN_SHARE_SYSTEM (#4023)Luca Bruno
This commit follows further on the deprecation path for --share-system, by splitting and gating each share-able namespace behind its own environment flag.
2016-08-25journal: implicitly flush to var on recovery (#4028)Vito Caputo
When the system journal becomes re-opened post-flush with the runtime journal open, it implies we've recovered from something like an ENOSPC situation where the system journal rotate had failed, leaving the system journal closed, causing the runtime journal to be opened post-flush. For the duration of the unavailable system journal, we log to the runtime journal. But when the system journal gets opened (space made available, for example), we need to close the runtime journal before new journal writes will go to the system journal. Calling server_flush_to_var() after opening the system journal with a runtime journal present, post-flush, achieves this while preserving the runtime journal's contents in the system journal. The combination of the present flushed flag file and the runtime journal being open is a state where we should be logging to the system journal, so it's appropriate to resume doing so once we've successfully opened the system journal.

2016-08-22bus-util: turn on exit-on-disconnect for all command line toolsLennart Poettering
bus_connect_transport() is exclusively used from our command line tools, hence let's set exit-on-disconnect for all of them, making behaviour a bit nicer in case dbus-daemon goes down.
2016-08-22sd-bus: optionally, exit process or event loop on disconnectLennart Poettering
Old libdbus has a feature that the process is terminated whenever the the bus connection receives a disconnect. This is pretty useful on desktop apps (where a disconnect indicates session termination), as well as on command line apps (where we really shouldn't stay hanging in most cases if dbus daemon goes down). Add a similar feature to sd-bus, but make it opt-in rather than opt-out, like it is on libdbus. Also, if the bus is attached to an event loop just exit the event loop rather than the the whole process.
2016-08-22sd-bus: add a small test case for sd_bus_trackLennart Poettering
This tests in particular that disconnecting results in the tracking object's handlers to be called.

objects immediately If the server side kicks us from the bus, from our view no names are on the bus anymore, hence let's make sure to dispatch all tracking objects immediately.
