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.
2016-04-29networkd: 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

2016-04-26smaller journal fixes (#3124)Lennart Poettering
* sd-journal: detect earlier if we try to read an object from an invalid offset Specifically, detect early if we try to read from offset 0, i.e. are using uninitialized offset data. * journal: when dumping journal contents, react nicer to lines we can't read If journal files are not cleanly closed it might happen that intermediaery journal entries cannot be read. Handle this nicely, skip over the unreadable entries, and log a debug message about it; after all we generally follow the logic that we try to make the best of corrupted files. * journal-file: always generate the same error when encountering corrupted files Let's make sure EBADMSG is the one error we throw when we encounter corrupted data, so that we can neatly test for it. * journal-file: when iterating through a partly corruped journal file, treat error like EOF When we linearly iterate through a corrupted journal file, and we encounter a read error, don't consider this fatal, but merely as EOF condition (and log about it). * journal-file: make seeking in corrupted files work Previously, when we used a bisection table for seeking through a corrupted file, and the end of the bisection table was corrupted we'd most likely fail the entire seek operation. Improve the situation: if we encounter invalid entries in a bisection table, linearly go backwards until we find a working entry again. * man: elaborate on the automatic systemd-journald.socket service dependencies Fixes: #1603

2016-04-25man: don't include history sections in man pagesLennart Poettering
I am pretty sure we shouldn't carry history sections in man pages, since it's very hard to keep them correctly updated, the current ones are very out-of-date, and they tend to make APIs appear unnecessarily complex.

2016-04-21systemctl,pid1: do not warn about missing install info with "preset"Zbigniew Jędrzejewski-Szmek
When "preset" was executed for a unit without install info, we'd warn similarly as for "enable" and "disable". But "preset" is usually called for all units, because the preset files are provided by the distribution, and the units are under control of individual programs, and it's reasonable to call "preset" for all units rather then try to do it only for the ones that can be installed. We also don't warn about missing info for "preset-all". Thus it seems reasonable to silently ignore units w/o install info when presetting. (In addition, when more than one unit was specified, we'd issue the warning only if none of them had install info. But this is probably something to fix for enable/disable too.)

Kill user session scope by default
2016-04-21logind: make KillOnlyUsers override KillUserProcessesZbigniew Jędrzejewski-Szmek
Instead of KillOnlyUsers being a filter for KillUserProcesses, it can now be used to specify users to kill, independently of the KillUserProcesses setting. Having the settings orthogonal seems to make more sense. It also makes KillOnlyUsers symmetrical to KillExcludeUsers.
2016-04-21logind: flip KillUserProcesses to on by defaultZbigniew Jędrzejewski-Szmek
This ensures that users sessions are properly cleaned up after. The admin can still enable or disable linger for specific users to allow them to run processes after they log out. Doing that through the user session is much cleaner and provides better control. dbus daemon can now be run in the user session (with --enable-user-session, added in 1.10.2), and most distributions opted to pick this configuration. In the normal case it makes a lot of sense to kill remaining processes. The exception is stuff like screen and tmux. But it's easy enough to work around, a simple example was added to the man page in previous commit. In the long run those services should integrate with the systemd users session on their own. https://bugs.freedesktop.org/show_bug.cgi?id=94508 https://github.com/systemd/systemd/issues/2900
2016-04-21man: expand description of lingering and KillUserProcesses settingZbigniew Jędrzejewski-Szmek
The description in the man page was wrong, KillUserProcesses does not kill all processes of the user. Describe what the setting does, and also add links between the relavant sections of the manual. Also, add an extensive example which shows how to launch screen in the background.

2016-04-20networkd: bump MTU to 1280 for interfaces which have IPv6 enabled (#3077)Susant Sahani
IPv6 protocol requires a minimum MTU of 1280 bytes on the interface. This fixes #3046. Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled. Introduce network_has_static_ipv6_addresses() to find out if any static ipv6 address configured. If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static IPv6 addresses not configured, then IPv6 will be automatically disabled for that interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.
2016-04-20tmpfiles: add new 'e' action which cleans up a dir without creating itZbigniew Jędrzejewski-Szmek
I wanted to add a config line that would empty a directory without creating it if doesn't exist. Existing actions don't allow this. v2: properly add 'e' to needs_glob() and takes_ownership()
2016-04-20man: try to explain different actions in tmpfiles a bit betterZbigniew Jędrzejewski-Szmek
- do not suggest that vendor configuration files should be in /etc, use /usr/lib/tmpfiles.d instead - split the first example, because the text talked about "needing two directories", but then a smack attribute was also set, and on a different path, which looked like a typo. Replace that with the example from original patch [1] which added 't'. - fix the example for /var/tmp/abrt. The 'x' line was redundant, because /var/tmp/abrt/* is already filtered because "d /var/tmp/abrt" overrides "d /var/tmp". [1] http://permalink.gmane.org/gmane.comp.sysutils.systemd.devel/25051

2016-04-12man: shorten the list of unit file paths a bitLennart Poettering
Let's make this more digestable to read by making the list of documented unit file paths a bit shorter. Specifically, let's drop references to $XDG_CONFIG_HOME and $XDG_DATA_HOME, as their default values are listed too already. Given that the fact that the XDG basedir spec makes these paths configurable is probably not a strong point of the spec, let's drop the reference to the env vars, and keep only the literal, default paths for them in the list. Of course, we do support the full XDG basedir spec in this regard, but it's one thing to implement it and another one to recommend it by documenting it. Replace "$HOME" by "~", because UNIX.

2016-04-11nspawn: always setup machine idMichal Sekletar
We check /etc/machine-id of the container and if it is already populated we use value from there, possibly ignoring value of --uuid option from the command line. When dealing with R/O image we setup transient machine id. Once we determined machine id of the container, we use this value for registration with systemd-machined and we also export it via container_uuid environment variable. As registration with systemd-machined is done by the main nspawn process we communicate container machine id established by setup_machine_id from outer child to the main process by unix domain socket. Similarly to PID of inner child.
