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.
If we don't have TPM support then `alg` is NULL and passing this to
table_new() means we'd get a table with only two columns instead of
three, leading up to a very confusing output:
$ build/systemd-analyze pcrs
System lacks full TPM2 support, not showing PCR state.
NR NAME
0 platform-code
- 1
platform-config -
2 external-code
- 3
external-config -
4 boot-loader-code
- 5
boot-loader-config -
6 -
- 7
...
Let's name the header in this case with a simple dash, as it's going
to be hidden anyway, to make the table nice again:
$ build/systemd-analyze pcrs
System lacks full TPM2 support, not showing PCR state.
NR NAME
0 platform-code
1 platform-config
2 external-code
3 external-config
4 boot-loader-code
5 boot-loader-config
6 -
7 secure-boot-policy
...
This commits adds version_is_valid_versionspec and uses it in
analyze-compare-version.c.
version_is_valid_versionspec differs from version_is_valid in that it acepts
empty strings and since valid characters in a version spec version are all
ASCII letters and digits as well as "-.~^", but ",_+" allowed by
version_is_valid are not.
Also give a more specific warning message on invalid characters.
I figure these messages are rather unnecessary, so let the user quiet
them with the existing --quiet flag if desired. Makes systemd-analyze
condition a little more ergonomic in scripts.
It's highly interesting to see if tools such as systemd-sysupdate
consider a version valid, hence let's output that too (though
gracefully, not fatally)
Let's use the same common directory as the unit logic uses.
This means we have less to clean up, and opens the door to eventually
allow unprivileged operation of the
mount_image_privately_interactively() logic.
It's a sycall group of our own definition, and the output is erroneous
to claim otherwise. Let's hide it.
This adds syscall_set_add() which is nicely symmetric to the existing
syscall_set_remove().

In various tools and services we have a per-system and per-user concept.
So far we sometimes used a boolean indicating whether we are in system
mode, or a reversed boolean indicating whether we are in user mode, or
the LookupScope enum used by the lookup path logic.
Let's address that, in introduce a common enum for this, we can use all
across the board.
This is mostly just search/replace, no actual code changes.
Although this slightly more verbose it makes it much easier to reason
about. The code that produces the tests heavily benefits from this.
Test lists are also now sorted by test name.
-1 was used everywhere, but -EBADF or -EBADFD started being used in various
places. Let's make things consistent in the new style.
Note that there are two candidates:
EBADF 9 Bad file descriptor
EBADFD 77 File descriptor in bad state
Since we're initializating the fd, we're just assigning a value that means
"no fd yet", so it's just a bad file descriptor, and the first errno fits
better. If instead we had a valid file descriptor that became invalid because
of some operation or state change, the other errno would fit better.
In some places, initialization is dropped if unnecessary.
The name "def.h" originates from before the rule of "no needless abbreviations"
was established. Let's rename the file to clarify that it contains a collection
of various semi-related constants.
Similarly to DumpByFileDescriptor vs Dump,
DumpUnitsMatchingPatternsByFileDescriptor is used in preference. Dissimilarly,
a fallback to DumpUnitsMatchingPatterns is not done on error, because there is
no need for backwards compatibility.
The code is still more verbose than I'd like, but there are four different code
paths with slightly different rules in each case, so it's hard to make this all
very brief. Since we have a separate file dedicated to making those calls, the
verbose-but-easy-to-follow implementation should be OK.
Closes#24989.
I only did a quick test that all both variants works locally and over ssh.
