2014-07-17shared: add generic IPC barrierDavid Herrmann
The "Barrier" object is a simple inter-process barrier implementation. It allows placing synchronization points and waiting for the other side to reach it. Additionally, it has an abortion-mechanism as second-layer synchronization to send abortion-events asynchronously to the other side. The API is usually used to synchronize processes during fork(). However, it can be extended to pass state through execve() so you could synchronize beyond execve(). Usually, it's used like this (error-handling replaced by assert() for simplicity): Barrier b; r = barrier_init(&b); assert_se(r >= 0); pid = fork(); assert_se(pid >= 0); if (pid == 0) { barrier_set_role(&b, BARRIER_CHILD); ...do child post-setup... if (CHILD_SETUP_FAILED) exit(1); ...child setup done... barrier_place(&b); if (!barrier_sync(&b)) { /* parent setup failed */ exit(1); } barrier_destroy(&b); /* redundant as execve() and exit() imply this */ /* parent & child setup successful */ execve(...); } barrier_set_role(&b, BARRIER_PARENT); ...do parent post-setup... if (PARENT_SETUP_FAILED) { barrier_abort(&b); /* send abortion event */ barrier_wait_abortion(&b); /* wait for child to abort (exit() implies abortion) */ barrier_destroy(&b); ...bail out... } ...parent setup done... barrier_place(&b); if (!barrier_sync(&b)) { ...child setup failed... ; barrier_destroy(&b); ...bail out... } barrier_destroy(&b); ...child setup successfull... This is the most basic API. Using barrier_place() to place barriers and barrier_sync() to perform a full synchronization between both processes. barrier_abort() places an abortion barrier which superceeds any other barriers, exit() (or barrier_destroy()) places an abortion-barrier that queues behind existing barriers (thus *not* replacing existing barriers unlike barrier_abort()). This example uses hard-synchronization with wait_abortion(), sync() and friends. These are all optional. Barriers are highly dynamic and can be used for one-way synchronization or even no synchronization at all (postponing it for later). The sync() call performs a full two-way synchronization. The API is documented and should be fairly self-explanatory. A test-suite shows some special semantics regarding abortion, wait_next() and exit(). Internally, barriers use two eventfds and a pipe. The pipe is used to detect exit()s of the remote side as eventfds do not allow that. The eventfds are used to place barriers, one for each side. Barriers itself are numbered, but the numbers are reused once both sides reached the same barrier, thus you cannot address barriers by the index. Moreover, the numbering is implicit and we only store a counter. This makes the implementation itself very lightweight, which is probably negligible considering that we need 3 FDs for a barrier.. Last but not least: This barrier implementation is quite heavy. It's definitely not meant for fast IPC synchronization. However, it's very easy to use. And given the *HUGE* overhead of fork(), the barrier-overhead should be negligible.
2014-07-16test-tables: add new entriesZbigniew Jędrzejewski-Szmek
One missing string found. A few things had to be moved around to make it possible to test them.
2014-07-16build-sys: don't move libgudev to /libMichael Biebl
It depends on libgobject and libgmodule which are installed in /usr/lib.

2014-07-15journal-upload: a tool to push messages to systemd-journal-remoteZbigniew Jędrzejewski-Szmek
2014-07-15Move network-related journal programs to src/journal-remote/Zbigniew Jędrzejewski-Szmek
Directory src/journal has become one of the largest directories, and since systemd-journal-gatewayd, systemd-journal-remote, and forthcoming systemd-journal-upload are all closely related, create a separate directory for them.

2014-07-16resolved: add small NSS module that uses resolved to resolve DNS namesLennart Poettering
2014-07-16resolved: add a DNS client stub resolverLennart Poettering
Let's turn resolved into a something truly useful: a fully asynchronous DNS stub resolver that subscribes to network changes. (More to come: caching, LLMNR, mDNS/DNS-SD, DNSSEC, IDN, NSS module)
2014-07-15shell-completion: restore completion for -pZbigniew Jędrzejewski-Szmek
It was broken since systemd was moved out of /bin. For zsh it was never there.

2014-07-11build-sys: Do not distribute generated emergency.serviceJon Severinsson
It is already in nodist_systemunit_DATA and if it is shipped, it contains the hardcoded path to systemctl which will cause it to fail to start when rootprefix != prefix and rootbindir != bindir.
2014-07-11Revert "build-sys: include PolicyKit files as part of distribution"Mike Gilbert
This reverts commit 0c26bfc3d21fdb3963f1248c237e2f1a33b5566d. src/core/org.freedesktop.systemd1.policy.in.in depends on values which are specified at configure time, so we cannot ship the corresponding policy file in the tarball. Since we need to regenerate one policy file, we might as well generate them all.

private in-addr-util.[ch] These are enough calls for a new file, and they are sufficiently different from the sockaddr-related calls, hence let's split this out.

2014-07-09timedated: manage systemd-timesyncd directly instead of lists of alternativesKay Sievers
Alternative NTP implementations should add a: Conflicts=systemd-timesyncd.service to take over the built-in NTP functionality of systemd.
2014-07-08escape: move to rootbindirMichael Biebl
The systemd-escape utility might be used during early boot (e.g. when being triggered from udev rules), so move it to rootbindir to support systems with a split /usr setup.

2014-07-07networkd: add support for modeSusant Sahani
This patch adds supports networkd to configure bond mode during creation via persistent conf. Mode can be configured with conf param 'Mode'. A new section Bond is added to the conf to support bond mode. These modes can be configured now. balance-rr active-backup balance-xor broadcast 802.3ad balance-tlb balance-alb Example conf file: test-bond.conf [NetDev] Name=bond1 Kind=bond [Bond] Mode=balance-xor Test case: 1. start networkd service: 12: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/ether 22:89:6c:47:23:d2 brd ff:ff:ff:ff:ff:ff 2. find bond mode: cat /proc/net/bonding/bond1 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: load balancing (xor) Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 Changes: 1.

2014-07-07firstboot: get rid of firstboot generator again, introduce ↵Lennart Poettering
ConditionFirstBoot= instead As Zbigniew pointed out a new ConditionFirstBoot= appears like the nicer way to hook in systemd-firstboot.service on first boots (those with /etc unpopulated), so let's do this, and get rid of the generator again.
2014-07-07firstboot: add new component to query basic system settings on first boot, ↵Lennart Poettering
or when creating OS images offline A new tool "systemd-firstboot" can be used either interactively on boot, where it will query basic locale, timezone, hostname, root password information and set it. Or it can be used non-interactively from the command line when prepareing disk images for booting. When used non-inertactively the tool can either copy settings from the host, or take settings on the command line. $ systemd-firstboot --root=/path/to/my/new/root --copy-locale --copy-root-password --hostname=waldi The tool will be automatically invoked (interactively) now on first boot if /etc is found unpopulated. This also creates the infrastructure for generators to be notified via an environment variable whether they are running on the first boot, or not.
2014-07-07shared: make timezone and locale enumeration and validation genericLennart Poettering
This way we can reuse it other code thatn just localectl/localed + timedatectl/timedated.
2014-07-06compress: add benchmark-style testZbigniew Jędrzejewski-Szmek
This is useful to test the behaviour of the compressor for various buffer sizes. Time is limited to a minute per compression, since otherwise, when LZ4 takes more than a second which is necessary to reduce the noise, XZ takes more than 10 minutes. % build/test-compress-benchmark (without time limit) XZ: compressed & decompressed 2535300963 bytes in 794.57s (3.04MiB/s), mean compresion 99.95%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.56s (1550.07MiB/s), mean compresion 99.60%, skipped 990 bytes % build/test-compress-benchmark (with time limit) XZ: compressed & decompressed 174321481 bytes in 60.02s (2.77MiB/s), mean compresion 99.76%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.63s (1480.83MiB/s), mean compresion 99.60%, skipped 990 bytes It appears that there's a bug in lzma_end where it leaks 32 bytes.
2014-07-06journal: add LZ4 as optional compressorZbigniew Jędrzejewski-Szmek
Add liblz4 as an optional dependency when requested with --enable-lz4, and use it in preference to liblzma for journal blob and coredump compression. To retain backwards compatibility, XZ is used to decompress old blobs. Things will function correctly only with lz4-119. Based on the benchmarks found on the web, lz4 seems to be the best choice for "quick" compressors atm. For pkg-config status, see http://code.google.com/p/lz4/issues/detail?id=135.

2014-07-03networkd: Introduce tun/tap deviceSusant Sahani
This patch introduces TUN/TAP device creation support to networkd. Example conf to create a tap device: file: tap.netdev ------------------ [NetDev] Name=tap-test Kind=tap [Tap] OneQueue=true MultiQueue=true PacketInfo=true User=sus Group=sus ------------------ Test: 1. output of ip link tap-test: tap pi one_queue UNKNOWN_FLAGS:900 user 1000 group 1000 id: uid=1000(sus) gid=10(wheel) groups=10(wheel),1000(sus) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 Modifications: Added: 1. file networkd-tuntap.c 3. netdev kind NETDEV_KIND_TUN and NETDEV_KIND_TAP 2. Tun and Tap Sections and config params to parse conf and gperf conf parameters [tomegun: tweak the 'kind' checking for received ifindex]

2014-07-02path: add new "systemd-path" utility for querying paths described in ↵Lennart Poettering
file-hierarchy(7) This new tool is based on "sd-path", a new (so far unexported) API for libsystemd, that can hopefully grow into a workable API covering /opt and more one day.
2014-07-01networkd: netdev - add dummy supportTom Gundersen
2014-06-30Move x-systemd-device.timeout handling from core to fstab-generatorZbigniew Jędrzejewski-Szmek
Instead of adjusting job timeouts in the core, let fstab-generator write out a dropin snippet with the appropriate JobTimeout. x-systemd-device.timeout option is removed from Options= line in the generated unit. The functions to write dropins are moved from core/unit.c to shared/dropin.c, to make them available outside of core. generator.c is moved to libsystemd-label, because it now uses functions defined in dropin.c, which are in libsystemd-label.
2014-06-30pc: expose more drop-in dirs in the .pc fileLennart Poettering
2014-06-29sysusers: split up default sysusers snippetLennart Poettering
This ways, distributions have an easier way to replace the OS specific generic groups/users while keeping systemd's own.
2014-06-27coredump: add simple coredump vacuumingLennart Poettering
When disk space taken up by coredumps grows beyond a configured limit start removing the oldest coredump of the user with the most coredumps, until we get below the limit again.
2014-06-26build-sys: include PolicyKit files as part of distributionFilipe Brandenburger
So that building from an archive works even if intltool is not present. The README file already mentioned that intltool should only be required when building from git. Tested: Built it from the distribution archive on a host without intltool. $ ./configure --enable-polkit $ make
2014-06-26install: enable timesyncd by defaultMichael Olbrich
This treats it similarly to networkd, resolved and others and it matches what 90-systemd.preset does.
