systemctl: do not show preset state for "static"/"alias"/"generated"/"transient" units

This modifies list-unit-files and status.

The output of list-unit-files would contain various lines with "static
disabled", which is just misleading, because systemctl preset will not touch
those files, so the preset configuration is not relevant. Similarly, for
"generated" and "transient" units, preset state is irrelevant. For "alias"
lines, the preset for the alias target would be used. In all cases let's just
skip preset status in those cases.

(It turns out that most of the services on this list that are enabled without a
corresponding preset are against rpm packaging and do direct 'systemctl enable'
calls in %post, instead of going through presets as they are supposed to.)

systemctl: also skip preset status in status verb

systemctl: add new enablement state "alias"

For units which are aliases of other units, reporting preset status as
"enabled" is rather misleading. For example, dbus.service is an alias of
dbus-broker.service. In list-unit-files we'd show both as "enabled".  In
particular, systemctl preset ignores aliases, so showing any preset status at
all is always going to be misleading. Let's introduce a new state "alias" and
use that for all aliases.

I was trying to avoid adding a new state, to keep compatibility with previous
behaviour, but for alias unit files it simply doesn't seem very useful to show
any of the existing states. It seems that the clearly showing that those are
aliases for other units will be easiest to understand for users.

shared/install: rename variable for clarity

shared/install: print name of offending file in error

"Unit type slice cannot be templated."
↓
"/etc/systemd/system.control/user@.slice: unit type slice cannot be templated."

shared/install: indent tables

shared/install: optionally cache the preset list

When doing list-unit-files with --root, we would re-read the preset
list for every unit. This uses a cache to only do it once. The time
for list-unit-files goes down by about ~30%.

unit_file_query_preset() is also called from src/core/. This patch does not
touch that path, since the saving there are smaller, since preset status is
only read on demand over dbus, and caching would be more complicated.

systemctl: fix --root support in querying presets

We would always look on the host, ignoring --root.

systemctl: refuse online-only ops with --root

It is super confusing when a command does not support --root, and is called
with it specified, and returns some bogus results. Let's just catch this
early and refuse.

shared/verbs: split out helper to find verbs

It will be used later, but I think it makes the code clearer anyway.

Also change the message about ignoring to include the name for default
verbs.

shared/verbs: add a modicum of documentation

systemctl: mark log-level,log-target,service-watchdogs as online-only

They were added in 6ab863190dee5ab631795ef547fcc7314ddccd40 and
38fcb7f766c84736425e86854b8a4468c126dafa. I don't see a good reason to
exclude them from the online-only check.

systemctl: fix hint when 'systemctl help' is given

Not all verbs require unit names, but that is beside the point. We need a verb
here, and help is not a valid verb.

shared/unit-file: fix resolution of absoulute symlinks with --root

$ systemctl --no-pager --root /tmp/root2/ cat ctrl-alt-del.target
Failed to resolve symlink /tmp/root2/etc/systemd/system/ctrl-alt-del.target pointing to /usr/lib/systemd/system/reboot.target, ignoring: Channel number out of range

man: mention that ProtectSystem= also takes care of /efi

efi: cache test results of boolean EFI state functions

EFI variable access is nowadays subject to rate limiting by the kernel.
Thus, let's cache the results of checking them, in order to minimize how
often we access them.

Revert "detect-virt: also detect "microsoft" as WSL"

WSL2 will soon (TM) include the "WSL2" string in /proc/sys/kernel/osrelease
so the workaround will no longer be necessary.
We have several different cloud images which do include the "microsoft"
string already, which would break this detection. They are for internal
usage at the moment, but the userspace side can come from all over the
place so it would be quite hard to track and downstream-patch to avoid
breakages.

This reverts commit a2f838d59075a49b012f9b7056664f7ffeed44d2.

Normally it takes ~0.02s, but here there's a slowdown to 0.73 and things fail with EINTR.
This happens only occasionally, and I haven't been able to capture a strace.

It would be to ignore that case in test-boot-timestamps or always translate
EINTR to -ENODATA. Nevertheless, I think it's better to retry, since this gives
as more resilient behaviour and avoids a transient failure.

shell-completion/zsh: update systemd-analyze completions

zsh: fix disable/enable completion

The "preset" column introduced in
b01c1f305c044a381ad110709a62507d74bf6d86 breaks zsh completion for
systemctl disable/enable. Fix by ignoring everything after the last
space in a line.

tests: various small fixes for strict systems

Don't assume that 4MB can be allocated from stack since there could be smaller
DefaultLimitSTACK= in force, so let's use malloc(). NUL terminate the huge
strings by hand, also ensure termination in test_lz4_decompress_partial() and
optimize the memset() for the string.

Some items in /proc and /etc may not be accessible to poor unprivileged users
due to e.g. SELinux, BOFH or both, so check for EACCES and EPERM.

/var/tmp may be a symlink to /tmp and then path_compare() will always fail, so
let's stick to /tmp like elsewhere.

/tmp may be mounted with noexec option and then trying to execute scripts from
there would fail.

Detect and warn if seccomp is already in use, which could make seccomp test
fail if the syscalls are already blocked.

Unset $TMPDIR so it will not break specifier tests where %T is assumed to be
/tmp and %V /var/tmp.

sd-bus: Cite sd_bus_creds_unref in sd_bus_get_name_creds docs

test-cgroup: skip if /sys/fs/cgroup unknown fs

It's not always mounted, e.g. during the build-time tests, it's running inside
a chroot (that's how Debian/Ubuntu build packages, in chroots) so this test
always fails because /sys/fs/cgroup isn't mounted.

cgroup-util: check for SYSFS_MAGIC when detecting cgroup format

When nothing at all is mounted at /sys/fs/cgroup, the fs.f_type is
SYSFS_MAGIC (0x62656572) which results in the confusing debug log:

"Unknown filesystem type 62656572 mounted on /sys/fs/cgroup."

Instead, if the f_type is SYSFS_MAGIC, a more accurate message is:

"No filesystem is currently mounted on /sys/fs/cgroup."

man: add a description of handling of single-label names

It turns out that our man page didn't describe the handling of single-label
names almost at all. This probably adds to the confusion regarding the subject.
So let's first describe what our current implementation is doing.

Quoting https://www.iab.org/documents/correspondence-reports-documents/2013-2/iab-statement-dotless-domains-considered-harmful/:
> Applications and platforms that apply a suffix search list to a single-label
> name are in conformance with IETF standards track RFCs. Furthermore,
> applications and platforms that do not query DNS for a TLD are in conformance
> with IETF standards track recommendations

Current behaviour is in line with that recommendation.

man: document binfmt's new --unregister switch

binfmt: also unregister binfmt entries from unit

We unregister binfmt_misc twice during shutdown with this change:

1. A previous commit added support for doing that in the final shutdown
   phase, i.e. when we do the aggressive umount loop. This is the robust
   thing to do, in case the earlier ("clean") shutdown phase didn't work
   for some reason.

2. This commit adds support for doing that when systemd-binfmt.service
   is stopped. This is a good idea so that people can order mounts
   before the service if they want to register binaries from such
   mounts, as in that case we'll undo the registration on shutdown
   again, before unmounting those mounts.

And all that, just because of that weird "F" flag the kernel introduced
that can pin files...

Fixes: #14981

binfmt: modernize code a bit

Let's just copy out the bit of the string we need, and let's make sure
we refuse rules called "status" and "register", since those are special
files in binfmt_misc's file system.

shutdown: unregister all binfmt_misc entries before entering shutdown loop

Apparently if the new "F" flag is used they might pin files, which
blocks us from unmounting things. Let's hence clear this up explicitly.
Before entering our umount loop.

Follow-up for 9f65637308.

tmpfiles: if we get ENOENT when opening /proc/self/fd/, check if /proc is mounted

let's return ENOSYS in that case, to make things a bit less confusng.

Previously we'd just propagate ENOENT, which people might mistake as
applying to the object being modified rather than /proc/ just not being
there.

Let's return ENOSYS instead, i.e. an error clearly indicating that some
kernel API is not available. This hopefully should put people on a
better track.

Note that we only do the procfs check in the error path, which hopefully
means it's the less likely path.

We probably can add similar bits to more suitable codepaths dealing with
/proc/self/fd, but for now, let's pick to the ones noticed in #14745.

Fixes: #15395

tree-wide: use recvmsg_safe() at various places

Let's be extra careful whenever we return from recvmsg() and see
MSG_CTRUNC set. This generally means we ran into a programming error, as
we didn't size the control buffer large enough. It's an error condition
we should at least log about, or propagate up. Hence do that.

This is particularly important when receiving fds, since for those the
control data can be of any size. In particular on stream sockets that's
nasty, because if we miss an fd because of control data truncation we
cannot recover, we might not even realize that we are one off.

(Also, when failing early, if there's any chance the socket might be
AF_UNIX let's close all received fds, all the time. We got this right
most of the time, but there were a few cases missing. God, UNIX is hard
to use)
