seccomp: also detect if seccomp filtering is enabled

In https://github.com/systemd/systemd/pull/4004 , a runtime detection
method for seccomp was added. However, it does not detect the case
where CONFIG_SECCOMP=y but CONFIG_SECCOMP_FILTER=n. This is possible
if the architecture does not support filtering yet.
Add a check for that case too.

While at it, change get_proc_field usage to use PR_GET_SECCOMP prctl,
as that should save a few system calls and (unnecessary) allocations.
Previously, reading of /proc/self/stat was done as recommended by
prctl(2) as safer. However, given that we need to do the prctl call
anyway, lets skip opening, reading and parsing the file.

units: remove udev control socket when systemd stops the socket unit (#4039)

Mere presence of the socket in the filesystem makes
udev_queue_get_udev_is_active() return that udev is running. Note that,
udev on exit doesn't unlink control socket nor does systemd. Thus socket
stays around even when both daemon and socket are stopped. This causes
problems for cryptsetup because when it detects running udev it launches
synchronous operations that *really* require udev. This in turn may
cause blocking and subsequent timeout in systemd-cryptsetup on reboot
while machine is in a state that udev and its control socket units are
stopped, e.g. emergency mode.

journal: implicitly flush to var on recovery (#4028)

When the system journal becomes re-opened post-flush with the runtime
journal open, it implies we've recovered from something like an ENOSPC
situation where the system journal rotate had failed, leaving the system
journal closed, causing the runtime journal to be opened post-flush.

For the duration of the unavailable system journal, we log to the
runtime journal.  But when the system journal gets opened (space made
available, for example), we need to close the runtime journal before new
journal writes will go to the system journal.  Calling
server_flush_to_var() after opening the system journal with a runtime
journal present, post-flush, achieves this while preserving the runtime
journal's contents in the system journal.

The combination of the present flushed flag file and the runtime journal
being open is a state where we should be logging to the system journal,
so it's appropriate to resume doing so once we've successfully opened
the system journal.

8 years agoshared/install: properly report masked units listed in Also=

shared/install: properly report masked units listed in Also=

A masked unit is listed in Also=:

$ systemctl cat test1 test2
→# /etc/systemd/system/test1.service
[Unit]
Description=test service 1

[Service]
Type=oneshot
ExecStart=/usr/bin/true

[Install]
WantedBy=multi-user.target
Also=test2.service
Alias=alias1.service

→# /dev/null

$ systemctl --root=/ enable test1
(before)
Created symlink /etc/systemd/system/alias1.service → /etc/systemd/system/test1.service.
Created symlink /etc/systemd/system/multi-user.target.wants/test1.service → /etc/systemd/system/test1.service.
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.

Unit /etc/systemd/system/test2.service is masked, ignoring.

8 years agounits: install user units as real files, not symlinks to ../system/

units: install user units as real files, not symlinks to ../system/

This was causing preset-all --global to create symlinks:

$ systemctl preset-all --global --root=/var/tmp/inst1
Created symlink /var/tmp/inst1/etc/systemd/user/shutdown.target → /usr/lib/systemd/user/../system/shutdown.target.

Created symlink /var/tmp/inst1/etc/systemd/user/busnames.target → /usr/lib/systemd/user/../system/busnames.target.

It is better to create units in a state that completely matches the presets, i.e.
preset-all should do nothing when invoked immediately after installation.

I'm sure it was confusing to users too, suggesting that system and user units
may somehow alias each other.
