hwdb: Map 45 to bookmarks on the ThinkPad L380
The ThinkPad L380 has a F12(Favorate) key. The keycode 0x45 is mapped
to KEY_FAVORITES(0x16c) in kernel thinkpad_acpi driver, but this
keycode is too big for xorg to handle.
xkeyboard-config mapped KEY_BOOKMARKS to XF86Favorites:
ptyfwd: when we can't copy the window size from caller, use $LINES and $COLUMNS
This way users can directly influence the tty size if they like when
nspawn is invoked as a service and thus stdin/stdout/stderr are not
connected to a TTY.
Until a core dump handler is installed by systemd-sysctl, the generation of
core dump for services is turned OFF which can make the debugging of the early
boot process harder especially since there's no easy way to restore the core
dump generation.
This patch introduces a new kernel command line option which specifies an
absolute path where the kernel should write the core dump file when an early
process crashes.
This will take effect until systemd-coredump (or any other handlers) takes
over.
This shouldn't change control flow, with one exception: we won't send
notifications for boot progress to plymouth anymore during reload, which
is something we really shouldn't.
terminal-util: extra safety checks when parsing $COLUMNS or $LINES (#10314)
Let's make sure the integers we parse out are not larger than USHRT_MAX.
This is a good idea as the kernel's TIOCSWINSZ ioctl for sizing
terminals can't take larger values, and we shouldn't risk an overflow.
efivars: newer efivarfs sets FS_IMMUTABLE_FL by default, deal with that
On EFI variables that aren't whitelisted in the kernel the
FS_IMMUTABLE_FL is set, as protection against accidental
removal/modification. Since our own variables do not appear in those
whielists, and we are not changing these variables, let's unset the flag
temporarily when needed. We restore the flag after all writes, just in
case.
This is really confusing, let's try to clean this up a bit, in
particular as there are two very similar concepts:
1. The boot loaders, i.e. the category you find systemd-boot, the
Windows and Apple boot loaders in. These may typically be listed in the
firmware's EFI variables.
2. The boot loader entries, as defined by the Boot Loader Spec. In this
category you find the various Linux kernels that are installed, i.e.
the stuff systemd-boot shows on screen. To make things confusing, the
Windows and Apple boot loaders can appear both as boot loaders and as
boot loader entries.
This tries to establish the following nomenclature: "boot loaders" and
"boot loader entries" for these two concepts.
boot_loader_read_conf(), boot_entries_find(), boot_entries_load_config()
all log their errors internally, hence no need to log a second or third
time about the same error when they return.
efivars: check whether we are booted with EFI before reading/writing to variables
We do these checks only for the high-level calls as for the low-level
ones it might make sense in some exotic uses to read the host EFI data
from a container or so.
bootctl: let's be paranoid and synchronize the ESP in full after all changes
We already synchronize all files we write individually, as well as the
directories they are stored in. Let's also synchronize the ESP as a
whole after our work, just in case.
Note that this breaks compatibility with older versions, as the detach
code won't find unit files attached with older releases anymore. But
given that the portable service logic was not deemed stable so far, and
this was explicitly documented and enforced through portablectl's
installation to /usr/lib/systemd/ such a compat breakage should be fine.
path-lookup: define explicit unit file directory for attached unit files
Let's separate out the unit files copied from attached portable service
image files from the admin's own files. Let's introduce
/etc/systemd/system.attached/ + /run/systemd/system.attached/ for the
files of portable services, and leave /etc/systemd/system/ and
/run/systemd/system/ for the admin.
shared/sleep-config: add switches to kill specific sleep modes
/etc/systemd/sleep.conf gains four new switches:
AllowSuspend=, AllowHibernation=, AllowSuspendThenHibernate=, AllowHybridSleep=.
Disabling specific modes was already possible by masking suspend.target,
hibernate.target, suspend-then-hibernate.target, or hybrid-sleep.target.
But this is not convenient for distributions, which want to set some defaults
based on what they want to support. Having those available as configuration
makes it easy to put a config file in /usr/lib/systemd/sleep.conf.d/ that
overrides the defaults and gives instructions how to undo that override.

logind: ensure seat0 CanGraphical state is written
For non-`seat0` seats, attaching a graphics card to a seat can
lead to it getting created. This is because the graphics device
is a "master device" which means that device is a seat-defining
device.
`seat0` may get created, even before the graphics driver is loaded,
though. This is because the graphics driver is loaded
asynchronously at startup, and `seat0` is the primary seat of
system, associated with the system VTs.
When a graphics card is attached to a seat the `CanGraphical`
property on that seat will flip to `true`.
For seats that haven't been created yet (non-`seat0` seats), this
leads to `seat_start` getting called which ultimately causes the
seat to get serialized to `/run/systemd/seats`.
For `seat0`, which is already created, `seat_start` will return
immediately, which means the updated `CanGraphical` state will
never get written to `/run/systemd/seats`.
The end result is that clients querying `sd_seat_can_graphical`
won't get the correct answer for `seat0` in cases where the
graphics device takes a long time to load until some other peice
of seat state is updated.
This commit fixes the problem by calling `seat_save` explicitly
for already running seats at the time a graphics device is
attached.
