48f99d7c06 man: use --bus-introspect to autogenerate dbus api docs
This has the advantage that the executables are always in place and we don't
need any units to exist on the bus, so we can eventually hook this up into
a normal build system. (Probably as a build time check.)

f6e9aa9e45 pid1: convert to the new scheme
In all the other cases, I think the code was clearer with the static table.
Here, not so much. And because of the existing dump code, the vtables cannot
be made static and need to remain exported. I still think it's worth to do the
change to have the cmdline introspection, but I'm disappointed with how this
came out.

cd7e1e1a7f units: change description of systemd-logind.service
"Login Service" doesn''t explain much, esp. considering that logind is actually is
for logins. I think "User Login Management" is better, but not that great either.
Suggestions welcome.

6a7e98aaca sd-bus: add helper struct for interface definitions
The idea is to have a static table that defines the dbus API. The vtable is
defined right next to the interface name and path because they are logically
connected.

man: sd_notify() race is gone with sd_notify_barrier()
Add note for change of behaviour in systemd-notify, where parent pid trick
is only used when --no-block is passed, and with enough privileges ofcourse.

Also, fix a small error in systemd(1).

Introduce sd_notify_barrier
This adds the sd_notify_barrier function, to allow users to synchronize against
the reception of sd_notify(3) status messages. It acts as a synchronization
point, and a successful return gurantees that all previous messages have been
consumed by the manager. This can be used to eliminate race conditions where
the sending process exits too early for systemd to associate its PID to a
cgroup and attribute the status message to a unit correctly.

systemd-notify now uses this function for proper notification delivery and be
useful for NotifyAccess=all units again in user mode, or in cases where it
doesn't have a control process as parent.

cad6727906 test: find path for systemd-journal-remote
As Debian/Ubuntu use /lib/systemd instead of /usr/lib/systemd,
add systemd-journal-remote to the list of programs that test-functions
detects the correct path to, and replace its direct usage with
$SYSTEMD_JOURNAL_REMOTE

Also use $JOURNALCTL instead of journalctl.

Also minor correction in install_plymouth() to look in /lib/... as
well as /usr/lib/... and /etc/...

d446ae89c0 test: add test for cgroup v2 freezer support 2020-04-30 19:02:55 +02:00
Michal Sekletár
d9e45bc3ab core: introduce support for cgroup freezer
With cgroup v2 the cgroup freezer is implemented as a cgroup
attribute called cgroup.freeze. cgroup can be frozen by writing "1"
to the file and kernel will send us a notification through
"cgroup.events" after the operation is finished and processes in the
cgroup entered quiescent state, i.e. they are not scheduled to
run. Writing "0" to the attribute file does the inverse and process
execution is resumed.

This commit exposes above low-level functionality through systemd's DBus
API. Each unit type must provide specialized implementation for these
methods, otherwise, we return an error. So far only service, scope, and
slice unit types provide the support. It is possible to check if a
given unit has the support using CanFreeze() DBus property.

Note that DBus API has a synchronous behavior and we dispatch the reply
to freeze/thaw requests only after the kernel has notified us that
requested operation was completed.
