I don't quite understand the rationale of making these
verbs work with --global back in the day. But realistically
they interact with/spawn manager, while there's no
--global runtime scope manager. And to verify/inspect user
units it's sufficient to just use --user.
Fixes#31911
let's make userspace verity signature checking optional. This adds a
dissection flag to enable the logic and patches through all our users to
enable it by default, thus effectively not changing anything from the
status quo ante. However, know we have a knob to turn this off in
certain scenarios.
The command will refuse to write to a TTY, so give a strong hint
that redirecting to a file is recommended. This makes the synopsis,
man page text, and --help output consistent.
Also drop the space after the redirection operator everywhere.
Without `--root` or `--image`, the `security` command inspects all currently
loaded service units if no unit name is specified. But with `--root` or
`--image` with `--offline=true`, the `security` command exits silently if no
unit name is specified.
Also, fixed description of `--root` and `--image` in the man page, and added
missing `--unit` option to help text.
man:
- `verify` requires an argument
- `security` does not require an argument
- `fdstore` requires an argument
- `image-policy` requires an argument
`--help` text:
- missing `image-policy` command
- `cat-config` requires NAME or PATH
ExecStart= and friends for .service and .socket can be specified
multiple times.
This also checks all commands for .mount and .swap, not only for the
current control command.
The man page doesn't even mention errno. It just says that ferror() should
be used to check for errors. Those writes are unlikely to fail, but if they
do, errno might even be 0. Also, we have fflush_and_check() which does
additional paranoia around errno, because we apparently do not trust that
errno will always be set correctly.
If the requested unit is not in the current working directory, it is not
necessary to include the current working directory in SYSTEMD_UNIT_PATH.

Fixes#30166.
This is pretty low-level functionality, hence placed in systemd-analyze.
This is useful for working with systemd-cryptenroll --tpm2-device-key=,
as it acquires the SRK without requiring the full tpm2-tss tool set.
When looking at configuration, often a user wants to suppress the comments and
just look at the parts that actually configure something, roughly equivalent to
systemd-analyze cat-config … | rg -v '^(#|;|$)
This switch implements this natively, skipping lines that start with a comment
character or only contain whitespace.
For formats that have section headers, section headers are skipped, if only
followed by stuff that would be skipped. (The last section header is printed
when we're about to print some actual output.)
Note that the caller doesn't know if the format has headers or not. We do format
type detection in pretty-print.c. So the caller only specifies tldr=true|false, and
conf_files_cat() figures out if the format has headers and whether those should
be handled specially.
The comments that show the file name are always printed, even if all of the file
is suppressed.
This is a partial answer to the discussions in
https://github.com/systemd/systemd/pull/28919,
https://github.com/systemd/systemd/pull/29248. If the default config is shown in
config files, the user can conveniently use '--tldr' to show the relevant parts.
We generally prefer dealing with parsed data instead of original
strings, do so for the "rwm" strings too. We have to convert this to
flags for the primary backend implementation (BPF) anyway, hence we
can do this early to have simpler, shorter and more normalized code.
This helps a lot with figuring out why units were started when they
were, rather than guessing there is a dependency relation. We could
perhaps also do fun JavaScript things in the future to highlight
dependencies on mouse-over.
We so far maintained two places for symboic names for PCRs. One in
tpm2-util.h and one in tpm-pcr.h.
Let's unify this into one, i.e. move the full list from tpm2-util.h into
tpm-pcr.h, replacing the short list placed so far there.
Systematically prefix the definitions with TPM2_ or tpm2_, to follow how
we do this for all other defines in this context.
No change in behaviour, just unification of tables.
seccomp-util.h doesn't need ifdeffing, hence don't. It has worked since
quite a while with HAVE_SECCOMP is off, hence use it everywhere.
Also drop explicit seccomp.h inclusion everywhere (which needs
HAVE_SECCOMP ifdeffery everywhere). seccomp-util.h includes it anyway,
automatically, which we can just rely on, and it deals with HAVE_SECCOMP
at one central place.
