ptyfwd: when leaving a session with tinted background, clear to end of screen
So if we tint the background of a ptyfwd session with a color and the
session ends, then so far we reset the bg color and clear till the end
of line.
Let's instead clear till the end of the screen. This is nicer since it
means that any follow-up output will not be affected by the changed
background color anymore.

portable: log structured message when attach/detach succeeds
Currently portabled is completely silent (when not using debug level). But
when the system state is changed (ie: a portable is attached or detached)
there are no traces left in the journal. Log at info level when either of
those operations succeed, as they are effectively changing the state of
the system.
Create new MESSAGE_IDs for these logs, and also append PORTABLE_ROOT=
(and PORTABLE_EXTENSION= if any), like the units themselves are
configured to do via LogExtraFields=, so that the same metadata can
be found in the attach/detach messages and in logs from the units
themselves.
Let's put the run queue really the last spot, as we should only start
doing more work if we really have nothing else to do anymore.
Let's move the service watchdog after the rewatch PID logic for similar
logic: it will possibly result in new jobs being enqueued to stop
things, and we should really have done all other work first.
manager: process exec_fd (i.e. Type=exec) events before SIGCHLD events
We want to make sure we don't confuse the case "process started
successfully but then failed quickly" from the case "process failed to
start". Hence we need to make sure we take notice of Type=exec before we
bother with SIGCHLD.
Hence move EVENT_PRIORITY_EXEC_FD to the front. In fact, let's move it
even further up than SIGCHLD, i.e. before sd_notify() handling, so that
we don't end up processing service state change notifications before we
even considered that the service is properly started.
This also gives the cgroup OOM handling and the exec_fd handling
different priorities, to improve robustness of the system, we should act
quickly on OOM, and it doesn't matter if a service started succcessfully
if we have to act on OOM anyway.
This is based on Andrew Onyshchuk <andryk.rv@gmail.com> work here:
core: maintain a single table with event source priorities
It's hard to oversee the assigned processing priorities of the various
event sources we have. Let's unify them in a table (an enum), where we
can have a single consisten look at them, and then reference the table
entries by expressive symbols.
This doesn#t change behaviour in any way, it just gives each priority a
nice label, but doesn't change any of the priorities.

network/route: convert route before requesting
Previously,
1. use the passed Route object as is when a route is requested,
2. when the route becomes ready to configure, convert the Route object
if necessary, to resolve outgoing interface name, and split multipath
routes, and save them to the associated interfaces,
3. configure the route with the passed Route object.
However, there are several inconsistencies with what kernel does:
- The kernel does not merge nor split IPv4 multipath routes. However, we
unconditionally split multipath routes to manage.
- The kernel does not set gateway or so to a route if it has nexthop ID.
Fortunately, I do not find any issues caused by the inconsistencies. But
for safety, let's manage routes in a consistent way with the kernel.
This makes,
1. when a route is requested, split IPv6 multipath routes, but keep IPv4
multipath routes as is, and queue (possibly multiple) requests for
the route.
2. when the route becomes ready to configure, resolve nexthop and interface
name, and requeue request if necessary.
3. configure the (possibly split) route.
By using the logic,
- Now we manage routes in a mostly consistent way with the kernel.
- We can drop ConvertedRoutes object.
- Hopefully the code becomes much simpler.

Measure empty PK and KEK EFI vars
The OVMF UEFI firmware is measuring PK and KEK when secure boot is
disabled, and those variables are absent. This can be checked via the
event log to see that there are extensions for PCR 7 associated with PK
and KEK events of type EV_EFI_VARIABLE_DRIVER_CONFIG.
When running the "lock-secureboot-policy" verb, pcrlock complains that
those variables are not found and refuse to generate the
240-secureboot-policy.pcrlock.d/generated.pcrlock file.
The "TCG PC Client Platform Firmware Profile Specification Version 1.05
Revision 23"[1] from May 7, 2021, in section "3.3.4.8 PCR[7] - Secure
Boot Policy Measurements", point 10.b:
If reading a UEFI variable returns UEFI_NOT_FOUND, platform firmware
SHALL measure the absence of the variable. The
UEFI_VARIABLE_DATA.VariableDataLength field MUST be set to zero and
UEFI_VARIABLE_DATA.VariableData field will have a size of zero.
This patch mark those variables to be marked as "synthesize empty",
generating the correct hash for those variables.
dissect-image: introduce new get_common_dissect_directory() helper
So far, if some component mounts a DDI in some local mount namespace we
created a temporary mountpoint in /tmp/ for that. Let's instead use the
same directory inode in /run/ instead. This is safe, since if everything
runs in a local mount namespace (with propagation on /run/ off) then
they shouldn't fight for the inode. And it relieves us from having to
clean up the directory after use. Morever, it allows us to run without
/tmp/ mounted.
This only moves dissect-image.c and the dissec tool over. More stuff is
moved over later.
man: don't suggest using pam_unix.so's use_authtok switch
Our dumbed down example PAM stacks do not contain cracklib/pwq modules,
hence using use_authtok on the pam_unix.so password change stack won't
work, because it has the effect that pam_unix.so never asks for a
password on its own, expecting the cracklib/pwq modules to have
queried/validated them beforehand.
I noticed this issue because of #30969: Debian's PAM setup suffers by
the same issue – even though they don't actually use our suggested PAM
fragments at all.
mime: expose a mime type for encrypted credentials
Let's make things nice for desktops, and provide a mime type for
credential files.
This uses the 128bit header identifier that our credential files start
with. However, the files are always base64 encoded, hence we have to
match the base64 string, hence add a small test case that generates them
properly for us, and truncates them at the right place (since 128 is not
evently divisable by 6).

hibernate-util: log that we actually read /sys/power/resume* rather than cmdline
/sys/power/resume is always populated by the initrd, while
/sys/power/resume_offset might have been populated by

problem, since the previous log message suggested that resume=
is not set through kernel cmdline.
varlink: introduce varlink_call_and_log() which calls and then logs an error
As it turns out we do this in a similar way at various times (and
sometimes incorrectly), hence add a common implementation to share the
code and fix the incorrect behaviour.
varlink: drop "ret_flags" parameter from varlink_call()
The parameter returns the flags field of the reply message. This is only
relevant in very few cases, hence drop it from the call, but keep it in
a more generic varlink_call_full() call for those who need it.
varlink: if varlink_call() is called with ret_error_id=NULL propagate error via return value
It's OK if callers don't want to know the varlink error string. But in
that case return the fact the call failed via the return value, as a
negative errno as usual, to make sure it's not accidentally ignored.
varlink: in varlink_observe() correctly collect error parameters
In varlink errors can have parameters (and they regularly do, for
example the io.systemd.System error we generate carries the errno in its
parameter), hence it's essential that varlink_oberserve collects that
properly and returns it too.
