2015-03-13udev: make set_usec_initialized() internal to libudevTom Gundersen
Instead introduce ensure_usec_initialized(), which copies the timestamp if possible otherwise sets it to now(CLOCK_MONOTONIC).
2015-03-13sd-rtnl: read_message - don't set group if not neededTom Gundersen
2015-03-13sd-rtnl: process - only apply matches to broadcast messagesTom Gundersen
2015-03-13sd-rtnl: improve detection of broadcast messagesTom Gundersen
Do not rely on nl_pid == 0, but check the groups instead. We currently avoid using nl_pid == 0 for unicast anyway, so this should be redundant, but let's try to be correct.
2015-03-13sd-rtnl: never set serial to 0Tom Gundersen
In the unlikely event that we wrap the counter, skip 0 as this is used for broadcasts. Suggested by Richard Maw.
2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-13bus: stop using EDEADLOCKDavid Herrmann
The error code is called EDEADLK, stop using legacy names like EDEADLOCK. Note that _some_ weird architectures define them differently (namely, mips and sparc), but on all sane architectures they're exactly the same. So stay with the widely used code, which is EDEADLK.
2015-03-13journal-remote: stop using EWOULDBLOCKDavid Herrmann
There is no reason to ever use EWOULDBLOCK. It's equivalent to EAGAIN on all architectures on linux.
2015-03-13udev: dont use EWOULDBLOCKDavid Herrmann
EWOULDBLOCK is the same as EAGAIN, stop using it.

2015-03-13journal-remote: process events without delayZbigniew Jędrzejewski-Szmek
journal-remote buffers input, and then parses it handling one journal entry at a time. It was possible for useful data to be left in the buffer after some entries were processesed. But all data would be already read from the fd, so there would be no reason for the event loop to call the handler again. After some new data came in, the handler would be called again, and would then process the "old" data in the buffer. Fix this by enabling a handler wherever we process input data and do not exhaust data from the input buffer (i.e. when EAGAIN was not encountered). The handler runs until we encounter EAGAIN. Looping over the input data is done in this roundabout way to allow the event loop to dispatch other events in the meanwhile. If the loop was inside the handler, a source which produced data fast enough could completely monopolize the process. https://bugs.freedesktop.org/show_bug.cgi?id=89516
2015-03-13journal-remote: check also for EWOULDBLOCKZbigniew Jędrzejewski-Szmek
This matches similar code elsewhere.

2015-03-12networkd: Begin with serial number 1 for netlink requestsRichard Maw
"Notifications are of informal nature and no reply is expected, therefore the sequence number is typically set to 0."[1] If networkd is started soon after recent netlink activity, then there will be messages with sequence number 0 in the buffer. The first thing networkd does is to request a dump of all the links. If it uses sequence number 0 for this, then it may confuse the dump request's response with that of a notification. This will result in it failing to properly enumerate all the links, but more importantly, when it comes to enumerate all the addresses, it will still have the link dump in progress, so the address enumeration will fail with -EBUSY.

2015-03-12core: add missing words to my fix of explanation of associativityTom Gundersen
2015-03-12udevd: improve handling of failed workerTom Gundersen
The information in the db is stale, so it does not make sense to expose it any longer. Also, don't drop the kernel event, but simply pass it on to userspace without ammending it.
2015-03-12udevd: don't free event when killing the worker, wait until it has been reapedTom Gundersen
This will allow us to clean up the device when we are notified about the worker being killed.
2015-03-12libudev: introduce clone_with_db()Tom Gundersen
This allows us to move the db reading from udevd to libudev.
2015-03-12libudev: monitor - fix error path in send_deviceTom Gundersen
Return -errno rather than -1 in case sendmsg() fails.
2015-03-12udevd: event - make db loading lazy in REMOVE event handlingTom Gundersen
We were explicitly eagerly loading the db, then deletenig the backing file and then processing the rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be lazy as everywhere else. This may save us a bit of work in casese where the db is not needed, but more importantly it hides some implementation details of libudev-device form udevd.
2015-03-12libudev: introduce udev_device_properties_copy()Tom Gundersen
To copy properties from one device to another. Drop the equivalent functionality from udevd.

2015-03-11cgtop: fix assert when not on ttyUmut Tezduyar Lindskog
systemd-cgtop --dept=1 -b -n 10 -d 0.1 | cat Assertion 'new_length >= 3' failed at src/shared/util.c:3 \ 595, function ellipsize_mem(). Aborting. Aborted (core dumped) (David: add comment)
2015-03-11core: fix cgroups-agent match for kdbusDavid Herrmann
On kdbus, we get cgroups-agent messages via the system bus, not the private systemd socket. Therefore, we must install the match properly or we will never receive cgroup notifications.
2015-03-11core: rewind message before forwarding itDavid Herrmann
Forwarding messages that are not rewinded will drop data. Fix this for cgroups-agent messages that we might remarshal before forwarding to the system bus.
2015-03-11bus: remarshal kdbus messages received from the kernelDavid Herrmann
If we receive an sd_bus_message from the kernel, m->kdbus will contain additional items that cannot be used when sending a message. Therefore, always remarshal the message if it is used again.
2015-03-11bus: drop redundant assignmentDavid Herrmann
This assignment is already done in the parent context, no need to do it again.

2015-03-11bus-proxy: complain only once about queue overflowsDavid Herrmann
If the local peer does not dispatch its incoming queue, the bus-proxy will slowly fill its outgoing queue. Once its full, it will continously complain that it cannot forward its messages. As it turns out, pulseaudio does have an idle background dbus connection that is not integrated into any mainloop (and given that gdbus and libdbus1 both support background shared connections, PA is probably not the only example), therefore, the bus-proxy will loudly complain if it cannot forward NameOwnerChanged events once the queue is full. This commit makes the proxy track queue-state and complain only once the queue runs full, not if it is already full. A PA bug-report (and patch) has been filed, and other applications should be fixed similarly. Hence, lets keep the error message, instead of dropping it. It's unused resources we really want to get rid of, so silencing the message does not really help (which is actually what dbus-daemon does).
2015-03-11terminal/sysview: introduce SETTLE eventsDavid Herrmann
This introduces a new SYSVIEW_EVENT_SETTLE notification that is sent after initial scanning via sysview is done. This is very handy to let the application raise warnings in case requested resources are not found during startup. The SETTLE event is sent after systemd-logind and udev enumerations are done. This event does in no way guarantee that a given resource is available. All it does is notify the application that scanning is done! You must not react to SETTLE if you don't have external synchronization with the resource you're waiting for. The main use-case for SETTLE is to run applications _inside_ of logind sessions and startup sysview. You really want to make sure that the own session you're running in was found during enumeration. If not, something is seriously wrong.
2015-03-11console: fix error-code inversionDavid Herrmann
The error-code propagated via sysview is always negative. Avoid multiplying by -1 before returning it. Otherwise, we will return >0 instead of <0, which will not be detected as error by sysview-core.

2015-03-10util: add rename_noreplaceAlban Crequy
renameat2() exists since Linux 3.15 but btrfs support for the flag RENAME_NOREPLACE was added later. This patch implements a fallback when renameat2() returns EINVAL. EINVAL is the error returned when the filesystem does not support one of the flags.
2015-03-10path-util: fix path_is_mount_point() for symlinksHarald Hoyer
path_is_mount_point() compares the mount_id of a directory and the mount_id of the parent directory. When following symlinks, the function to get the parent directory does not take the symlink into account. /bin -> /usr/bin with /usr being a mountpoint: mount_id of /bin with AT_SYMLINK_FOLLOW != mount_id of /
2015-03-10bus-proxy: add support for "GetConnectionCredentials" methodLukasz Skalski
GetConnectionCredentials method was added to dbus-1 specification more than one year ago. This method should return "[...] as many credentials as possible for the process connected to the server", but at this moment only "UnixUserID", "LinuxSecurityLabel" and "ProcessID" are defined by the specification. We should add support for next credentials after extending dbus-1 spec.

2015-03-10fsckd: clean up log messagesDidier Roche
Avoid double logs printing. Not that we don't return manager_update_global_progress() to the handler callback as if the console or plymouth isn't available momentarily, we still desire to handle future fd progress events if those are available again (like cancellation, reports…)
2015-03-10fsckd: Reduce the SAK window when writing to consoleDidier Roche
We don't want to keep /dev/console open all the time, but only open it when needed, to avoid interfering with SAK.

just a typo fix
2015-03-09Introduce loop_read_exact helperZbigniew Jędrzejewski-Szmek
Usually when using loop_read(), we want to read the full buffer. Add a helper that mirrors loop_write(), and returns 0 when full buffer was read, and an error otherwise. Use -ENODATA for the short read, to distinguish it from a read error.
