2016-05-01shared/install: warn about DefaultInstance in non-template unitsZbigniew Jędrzejewski-Szmek
[/etc/systemd/system/mnt-test.mount:6] DefaultInstance only makes sense for template units, ignoring.
2016-05-01Move no_instances information to shared/Zbigniew Jędrzejewski-Szmek
This way it can be used in install.c in subsequent commit.
2016-05-01shared/install: ignore Alias in [Install] of units which don't allow aliasesZbigniew Jędrzejewski-Szmek
A downside is that a warning about missing [Install] is printed: $ systemctl --root=/ enable mnt-test.mount [/etc/systemd/system/mnt-test.mount:5] Aliases are not allowed for mount units, ignoring. The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...). 4) In case of template units, the unit is meant to be enabled with some instance name specified. That's a bit misleading, but I don't see an easy way to fix this. But the situation is similar for many other parsing errors, so maybe that's OK.

2016-04-29man: document that some unit types do not support unit aliases via symlinksLennart Poettering
2016-04-29core: when encountering a symlink alias for non-aliasable units warn nicelyLennart Poettering
If the user defines a symlink alias for a unit whose type does not support aliasing, detect this early and print a nice warning. Fixe: #2730
2016-04-29hashmap: optimize set_put_strdup() a bitLennart Poettering
Hashing should be quicker than allocating, hence let's first check if the string already exists and only then allocate a new copy for it.
2016-04-29core: refuse merging on units when the unit type does not support aliasLennart Poettering
The concept of merging units exists so that we can create Unit objects for a number of names early, and then load them only later, possibly merging units which then turn out to be symlinked to other names. This of course only makes sense for unit types where multiple names per unit are supported. For all others, let's refuse the merge operation early.

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.

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

2016-04-27path-util: Add hidden suffixes for ucf (#3131)Martin Pitt
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.

2016-04-26systemd --user: call pam_loginuid when creating user@.service (#3120)Zbigniew Jędrzejewski-Szmek
This way the user service will have a loginuid, and it will be inherited by child services. This shouldn't change anything as far as systemd itself is concerned, but is nice for various services spawned from by systemd --user that expect a loginuid. pam_loginuid(8) says that it should be enabled for "..., crond and atd". user@.service should behave similarly to those two as far as audit is concerned. https://bugzilla.redhat.com/show_bug.cgi?id=1328947#c28
