2016-05-02machinectl: since clone/remove/copy verbs are possibly slow, turn off bus ↵Lennart Poettering
call timeout By default we timeout all bus calls, but if we know that these bus calls might be slow, let's explicitly turn the timeouts off.
2016-05-02machined: rework copy-from/copy-to operation to use generic Operation objectLennart Poettering
With this all potentially slow operations are done out-of-process, asynchronously, using the same "Operation" object.
2016-05-02machined: also make image removal operation asynchronousLennart Poettering
If we remove a directory image (i.e. not a btrfs snapshot) then things might get quite expensive, hence run this asynchronous in a forked off process, too.
2016-05-02machined: support non-btrfs file systems with "machinectl clone"Lennart Poettering
Fall back to a normal copy operation when the backing file system isn't btrfs, and hence doesn't support cheap snapshotting. Of course, this will be slow, but given that the execution is asynchronous now, this should be OK. Fixes: #1308
2016-05-02tree-wide: fix invocations of chattr_path()Lennart Poettering
chattr_path() takes two bitmasks, and no booleans. Fix the various invocations to do this properly.
2016-05-02copy: adjust directory times after writing to the directoryLennart Poettering
When recursively copying a directory tree, fix up the file times after having created all contents in it, so that our changes don't end up altering any of the directory times.
2016-05-02copy: return the right error when we can't open a fileLennart Poettering
2016-05-02image: enable btrfs quotas on the clone destination, not the sourceLennart Poettering
2016-05-02util: rework sigkill_wait() to not require pid_t pointerLennart Poettering
Let's make sigkill_wait() take a normal pid_t, and add sigkill_waitp() that takes a pointer (which is useful for usage in _cleanup_), following the usual logic we have for this.
2016-05-02machined: run clone operation asynchronously in the backgroundLennart Poettering
Cloning an image can be slow, if the image is not on a btrfs subvolume, hence let's make sure we do this asynchronously in a child process, so that machined isn't blocked as long as we process the client request. This adds a new, generic "Operation" object to machined, that is used to track these kind of background processes. This is inspired by the MachineOperation object that already exists to make copy operations asynchronous. A later patch will rework the MachineOperation logic to use the generic Operation instead.

core: introduce activation rate limit and parse nice levels and close sockets properly
2016-04-29update TODOLennart Poettering
2016-04-29core: merge service_connection_unref() into service_close_socket_fd()Lennart Poettering
We always call one after the other anyway, and this way service_set_socket_fd() and service_close_socket_fd() nicely match each other as one undoes the effect of the other.
2016-04-29core: rerun GC logic for a unit that loses a referenceLennart Poettering
Let's make sure when we drop a reference to a unit, that we run the GC queue on it again. This (together with the previous commit) should deal with the GC issues pointed out in: https://github.com/systemd/systemd/pull/2993#issuecomment-215331189
2016-04-29core: rework socket/service GC logicLennart Poettering
There's no need to set the no_gc bit for service units that socket units prepare, as we always keep a proper reference (as maintained by unit_ref_set()) on them, and such references are honoured by the GC logic anyway. Moreover, explicitly setting the no_gc bit is problematic if the socket gets GC'ed for a reason, as the service might then leak with the bit set.
2016-04-29hwdb: add missing newline so the hwdb buils correctly againLennart Poettering
2016-04-29socket: really always close auxiliary fds when closing socket fdsLennart Poettering
2016-04-29core: make parsing of RLIMIT_NICE aware of actual nice levelsLennart Poettering
2016-04-29core: make sure to close connection fd when we fail to activate a ↵Lennart Poettering
per-connection service Fixes: #2993 #2691
2016-04-29core: minor error path fixLennart Poettering
In service_set_socket_fd(), let's make sure that if we can't add the requested dependencies we take no possession of the passed connection fd. This way, we follow the strict rule: we take possession of the passed fd on success, but on failure we don't, and the fd remains in possession of the caller.
2016-04-29core: rename StartLimitInterval= to StartLimitIntervalSec=Lennart Poettering
We generally follow the rule that for time settings we suffix the setting name with "Sec" to indicate the default unit if none is specified. The only exception was the rate limiting interval settings. Fix this, and keep the old names for compatibility. Do the same for journald's RateLimitInterval= setting
2016-04-29core: move start ratelimiting check after condition checksLennart Poettering
With #2564 unit start rate limiting was moved from after the condition checks are to before they are made, in an attempt to fix #2467. This however resulted in #2684. However, with a previous commit a concept of per socket unit trigger rate limiting has been added, to fix #2467 more comprehensively, hence the start limit can be moved after the condition checks again, thus fixing #2684. Fixes: #2684
2016-04-29core: introduce activation rate limiting for socket unitsLennart Poettering
This adds two new settings TriggerLimitIntervalSec= and TriggerLimitBurst= that define a rate limit for activation of socket units. When the limit is hit, the socket is is put into a failure mode. This is an alternative fix for #2467, since the original fix resulted in issue #2684. In a later commit the StartLimitInterval=/StartLimitBurst= rate limiter will be changed to be applied after any start conditions checks are made. This way, there are two separate rate limiters enforced: one at triggering time, before any jobs are queued with this patch, as well as the start limit that is moved again to be run immediately before the unit is activated. Condition checks are done in between the two, and thus no longer affect the start limit.
2016-04-29build-sys: improve compat with older kernel headersLennart Poettering
In 4.2 kernel headers, some netlink defines are missing that we need. missing.h already can add them in, but currently makes this dependent on a definition that these kernels already have. Change the check hence to check for the newest definition in the table, so that the whole bunch of definitions as added in on all kernels lacking this.
2016-04-29path-util: also support ".old" and ".new" suffixes and recommend themZbigniew Jędrzejewski-Szmek
~ suffix works fine, but looks to much like it the file is supposed to be automatically cleaned up. For new versions of configuration files installers might want to using something that looks more permanent like foobar.new. So let's add treat ".old" and ".new" as special. Update test to match.
2016-04-29core: Filter by unit name behind the D-Bus, instead on the client side (#3142)kayrus
This commit improves systemd performance on the systems which have thousands of units.
2016-04-29Merge pull request #3126 from poettering/small-fixesZbigniew Jędrzejewski-Szmek
fsync directory when creating or rotating journal files and other small fixes, most importantly for the DHCP DUID code.
2016-04-29test-copy: never call alloca() in a loopLennart Poettering
That's a total no-no, hence rework this to use malloc()-based memory instead of alloca()-based memory. Also see CODING_STYLE about this.
2016-04-29copy: also copy AF_UNIX socketsLennart Poettering
We previously would fail with EOPNOTSUPP when encountering an AF_UNIX socket in the directory tree to copy. Fix that, and copy them too (even if they are dead in the result). Fixes: #2914

2016-04-29path-util: document that we shouldn't add further entries to ↵Lennart Poettering
hidden_or_backup_file() And let's add ".bak" as a generic suffix for backups, that people can use without having to register their stuff in our list.

2016-04-29networkd: clean up DUID code a bitLennart Poettering
Let's move DUID configuration into the [DHCP] section, since it only makes sense in a DHCP context, and should be close to the configuration of ClientIdentifier= and suchlike. This really shouldn't be a section of its own, we don't have any for any of our other per-protocol specific identifiers... Follow-up for #2890 #2943

2016-04-29parse-util: fix conversion from size_t on s390 (#3147)Lubomir Rintel
On s390 size_t is an unsigned long, nor an unsigned int. They both are of the same size and can be cast to each other safely, but the compiler still seems unhappy about incompatible pointers. Fixes: 7c2da2ca8

2016-04-28cgtop: initialize `ours' to NULL properly (#3139)Naohiro Aota
Running cgtop on a system, which lacks expecting stat file, results in a segfault. For example, a system with blkio tree but without cfq io scheduler, lacks "blkio.io_service_bytes". When the targeting cgroup's file does not exist, process() returns 0 and also does not modify `*ret' value (which is `*ours'). As a result, callers of refresh_one() can have bogus pointer, which result in SEGV. This patch just properly initialize the variable to NULL.
