tree-wide: switch remaining mount() invocations over to mount_nofollow_verbose()
(Well, at least the ones where that makes sense. Where it does't make
sense are the ones that re invoked on the root path, which cannot
possibly be a symlink.)
mount-util: rework umount_verbose() to take log level and flags arg
Let's make umount_verbose() more like mount_verbose_xyz(), i.e. take log
level and flags param. In particular the latter matters, since we
typically don't actually want to follow symlinks when unmounting.
core/namespace: drop bitfield annotations from boolean fields
Such microoptimization makes sense when the structure is used in many many copies,
but here's it's not, and the few bytes we save are not worth the extra code the
compiler has to generate:
Currently the systemd-shutdown command attempts to stop swaps, DM
(crypt, LVM2) and loop devices, but it doesn't attempt to stop MD
RAID devices, which means that if the RAID is set up on crypt,
loop, etc. device, it won't be able to stop those underlying devices.
This code extends the shutdown application to also attempt stopping
the MD RAID devices.
homed: make sure our worker processes finish before we exit
When exiting, let's explicitly wait for our worker processes to finish
first. That's useful if unmounting of /home/ is scheduled to happen
right after homed is down, as we then can be sure that the home
directories are properly unmounted and detached by the time homed is
fully terminated (otherwise it might happen that our worker gets killed
by the service manager, thus leaving the home directory and its backing
devices up/left for auto-clean which might be async).
homed: make it easier to run multiple instances of homed
When debugging homed while being logged into a user account manged by
homed it is a good idea to be able to run a second copy of homed. In
order to not collide with its AF_UNIX socket and bus name use, let's add
a new env var $SYSTEMD_HOME_DEBUG_SUFFIX, when set the busnames/socket
names are suffixed by it. When setting this while debugging one can
invoke an additional copy without interfering with the host one.
dissect: show partition output even if os-release is missing
It's just too useful to immediately see with "systemd-dissect" what
"systemd-repart" generated for us without having to populate it with
/etc/os-release. Hence let's log a message if /etc/os-release is
missing, but proceed otherwise and show the partition table.
dissect: always invalidate secondary arch partitions if we found primary arch
Let's suppress the secondary arch data, since we never ever want to
mount it if we found the primary arch.
Previously we only suppressed in the Verity case, but there's little
reason to entertain the idea of a secondary arch in non-Verity
environments either, we are not going to use them, and should not do
decryption or anything like that.
Different bios version includes different pn. Submitted change fixed my inverted screen after reboot.
I've stepped back to the bios version 5.11 28.04.2016 in an attempt to troubleshoot Windows Hello locking the sign
in on reboot. The screen again rotated, but 90 degrees to the right. I created a new hwdb line to resolve that issue. The bios version changes the dmi string including the svn and pn.
By default we'll run a container in --console=interactive and
--console=read-only mode depending if we are invoked on a tty or not so
that the container always gets a /dev/console allocated, i.e is always
suitable to run a full init system /as those typically expect a
/dev/console to exist).
With the new --console=autopipe mode we do something similar, but
slightly different: when not invoked on a tty we'll use --console=pipe.
This means, if you invoke some tool in a container with this you'll get
full inetractivity if you invoke it on a tty but things will also be
very nicely pipeable. OTOH you cannot invoke a full init system like
this, because you might or might not become a /dev/console this way...
Prompted-by: #17070
(I named this "autopipe" rather than "auto" or so, since the default
mode probably should be named "auto" one day if we add a name for it,
and this is so similar to "auto" except that it uses pipes in the
non-tty case).
nspawn: don't become TTY controller just to undo it later again
Instead of first becoming a controlling process of the payload pty
as side effect of opening it (without O_NOCTTY), and then possibly
dropping it again, let's do it cleanly an reverse the logic: let's open
the pty without becoming its controller first. Only after everything
went the way we wanted it to go become the controller explicitly.
This has the benefit that the PID 1 stub process we run (as effect of
--as-pid2) doesn't have to lose the tty explicitly, but can just
continue running with things. And we explicitly make the tty controlling
right before invoking actual payload.
In order to make sure everything works as expected validate that the
stub PID 1 in the container really has no conrolling tty by issuing the
TIOCNOTTY tty and expecting ENOTTY, and log about it.
This shouldn't change behaviour much, it just makes thins a bit cleaner,
in particular as we'll not trigger SIGHUP on ourselves (since we are
controller and session leader) due to TIOCNOTTY which we then have to
explicitly ignore.
dissect: wrap verity settings in new VeritySettings structure
Just some refactoring: let's place the various verity related parameters
in a common structure, and pass that around instead of the individual
parameters.
Also, let's load the PKCS#7 signature data when finding metadata
right-away, instead of delaying this until we need it. In all cases we
call this there's not much time difference between the metdata finding
and the loading, hence this simplifies things and makes sure root hash
data and its signature is now always acquired together.

udev: if a tablet has BTN_0, label it as ID_INPUT_TABLET_PAD
Graphics tablet devices comprise multiple event nodes, usually a Pen, Finger
and Pad node (that's how the kernel postfixes them). Pen and Pad are labeled
as ID_INPUT_TABLET but the pad doesn't actually send stylus events - it
doesn't usually have BTN_TOOL_PEN, merely BTN_STYLUS.
For the last several years, libwacom has set ID_INPUT_TABLET_PAD for all pad
devices known to it based on vid/pid and a "* Pad" name match. That does not
cover devices not in libwacom. libinput relies on ID_INPUT_TABLET_PAD to
initialize the pad backend.
We can't drop ID_INPUT_TABLET without breaking userspace, but we can add
ID_INPUT_TABLET_PAD ourselves - where a device has BTN_0 in addition to
BTN_STYLUS, let's add it as a pad.
There are some devices (notably: bamboos) that use BTN_LEFT instead of BTN_0
but they are relatively rare and there's a risk of mislabeling those devices,
so let's just stick with BTN_0 only.
This means that the dbus doc consistency checks will be enabled by default,
including in the CI. I think that will work better than current state where
people do not enable them and them follow-up patches for the docs like the
parent commit must be had.
