Sync up with recent kdbus changed:
* several ioctls gained .size and .items members (but still unused)
* CMD_SEND gained its own ioctl structure
* several members of kdbus_msg were dropped as they were only used during
SEND, not during RECV etc.
* CMD_RECV and CMD_SEND now share a kdbus_reply member which contains the
offset and size of the returned message.

for leaf units
Otherwise a slice or delegation unit might move PIDs around ignoring the
fact that it is attached to a subcgroup.

Stuff in src/shared/ should not use stuff from src/libsystemd/ really.

loop_write() didn't follow the usual systemd rules and returned status
partially in errno and required extensive checks from callers. Some of
the callers dealt with this properly, but many did not, treating
partial writes as successful. Simplify things by conforming to usual rules.

This way, we can ensure we have a more complete, up-to-date list of
capabilities around, always.

native API for this in libmount, as soon as that's stable

Let's add some syntactic sugar for iterating through inotify events, and
use it everywhere.

If a unit is set property by "systemctl set-property", a new dropin
file is generated. But the unit's dropin_paths and dropin_mtime are
not updated. So the unit is shown as need daemon reload.
Update unit dropin_paths and dropin_mtime also when dropin file is
written.

Support timer options --on-active=, --on-boot=, --on-startup=,
--on-unit-active=, --on-unit-inactive=, --on-calendar=. Each options
corresponding with OnActiveSec=, OnBootSec=, OnStartupSec=,
OnUnitActiveSec=, OnUnitInactiveSec=, OnCalendar= of timer
respectively. And OnCalendar= and WakeSystem= supported by
--timer-property= option like --property= of systemd-run.
And if --unit= option and timer options are specified the command can
be omitted. In this case, systemd-run assumes the target service is
already loaded. And just try to generate transient timer unit only.

it's not quite as destructive as it sounds nowadays

If a cgroup fails to be destroyed (most likely because there are still
processes running as part of a service after the main pid exits), don't
free and remove the cgroup unit from the manager. This fixes a
regression introduced by the cgroup rework in v205 where systemd would
forget about processes still running after the unit becomes inactive.
(This can happen when the main pid exits and KillMode=process or none).

config_parse_warn_compat is now always used for removed options.

We need original socket_fd around otherwise mac_selinux_get_child_mls_label
fails with -EINVAL return code. Also don't call setexeccon twice but rather pass
context value of SELinuxContext option as an extra argument.

machine-id
If /etc was read only at boot time with an empty /etc/machine-id, the latter
will be mounted as a tmpfs and get reset at each boot. If the system becomes rw
later, this functionality enables to commit in a race-free manner the
transient machine-id to disk.

During upgrades and when transitioning between different systemd
versions in initrd and on the host we have to expect that some
serialization fields are unknown or parse incorrectly. This shouldn't
really be considered an error, hence downgrade the log messages about
it to debug. This way we can still trace it, but it doesn't confuse
users.
This kinda reverts 46849c3f.

Overflow is very unlikely, since we are watching a privileged directory,
but could be triggered if thousands of mounts are suddently executed.

Fixup for 4a3a9ef610.

When creating a new mount unit after an event on /proc/self/mountinfo,
check the mount options as well as the fstype to determine if this is a
remote mount that requires network access.
|
|
This is an attempt to add it the remote-fs dependencies to a mount unit
if the options change, like when the utab options are picked up after
mountinfo has already been processed. It just adds the remote-fs
dependencies, leaving the local-fs ones in place.
With this change I always get mount units with proper remote-fs
dependencies when mounted with the _netdev option.
|
|
Parsing the mount table with libmount races against the mount command,
which will handle the actual mounting before updating utab. This means
the poll event on /proc/self/mountinfo can kick of a reparse in systemd
before the utab information is available.
This change adds in an additional event source using inotify to watch
for changes to utab. It only watches for IN_MOVED_TO events, matching
libmount behavior of always overwriting this file using rename(2).
This does add a second pass through the mount table parsing when utab is
updated.
|
|
This lets libmount add in user options from /run/mount/utab, like
_netdev which is needed to get proper ordering against remote-fs.target

Using the same scripts as in f647962d64e "treewide: yet more log_*_errno
+ return simplifications".
|

If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.
Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'
Plus some whitespace, linewrap, and indent adjustments.
|
|
sd_event_add_io() does not set errno, it returns negative errno.
Noticed during log_*_errno conversions.
|
|
|
|
|
|
Basically:
find . -name '*.[ch]' | while read f; do perl -i.mmm -e \
'local $/;
local $_=<>;
s/log_(debug|info|notice|warning|error|emergency)\("([^"]*)%s"([^;]*),\s*strerror\(-?([->a-zA-Z_]+)\)\);/log_\1_errno(\4, "\2%m"\3);/gms;print;' \
$f; done
Plus manual indentation fixups.
