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.

2016-04-29core: 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.

2016-04-29networkd: 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

2016-04-28cgtop: 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.

2016-04-28tree-wide: rename hidden_file to hidden_or_backup_file and optimizeZbigniew Jędrzejewski-Szmek
In standard linux parlance, "hidden" usually means that the file name starts with ".", and nothing else. Rename the function to convey what the function does better to casual readers. Stop exposing hidden_file_allow_backup which is rather ugly and rewrite hidden_file to extract the suffix first. Note that hidden_file_allow_backup excluded files with "~" at the end, which is quite confusing. Let's get rid of it before it gets used in the wrong place.

dirent_is_file_with_suffix If the file name is supposed to end in a suffix, there's not need to check the name against a list of "special" file names, which is slow. Instead, just check that the name doens't start with a period.

2016-04-27Stop syslog.socket when entering emergency mode (#3130)Martin Pitt
When enabling ForwardToSyslog=yes, the syslog.socket is active when entering emergency mode. Any log message then triggers the start of rsyslog.service (or other implementation) along with its dependencies such as local-fs.target and sysinit.target. As these might fail themselves (e. g. faulty /etc/fstab), this breaks the emergency mode. This causes syslog.socket to fail with "Failed to queue service startup job: Transition is destructive". Add Conflicts=syslog.socket to emergency.service to make sure the socket is stopped when emergency.service is started. Fixes #266

ucf is a standard Debian helper for managing configuration file upgrades which need more interaction or elaborate merging than conffiles managed by dpkg.

2016-04-27journal: set STATE_ARCHIVED as part of offlining (#2740)Vito Caputo
The only code path which makes a journal durable is via journal_file_set_offline(). When we perform a rotate the journal's header->state is being set to STATE_ARCHIVED prior to journal_file_set_offline() being called. In journal_file_set_offline(), we short-circuit the entire offline when f->header->state != STATE_ONLINE. This all results in none of the journal_file_set_offline() fsync() calls being reached when rotate archives a journal, so archived journals are never explicitly made durable. What we do now is instead of setting the f->header->state to STATE_ARCHIVED directly in journal_file_rotate() prior to journal_file_close(), we set an archive flag in f->archive for the journal_file_set_offline() machinery to honor by committing STATE_ARCHIVED instead of STATE_OFFLINE when set. Prior to this, rotated journals were never getting fsync() explicitly performed on them, since journal_file_set_offline() short-circuited. Obviously this is undesirable, and depends entirely on the underlying filesystem as to how much durability was achieved when simply closing the file. Note that this problem existed prior to the recent asynchronous fsync changes, but those changes do facilitate our performing this durable offline on rotate without blocking, regardless of the underlying filesystem sync-on-close semantics.

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
