This is a common case, and nothing noteworthy at all. For example, if we
establish an enumerator for listing all devices tagged by some tag, then
the per-tag dir is not going to exist if there are currently no devices
tagged that way, but that's a really common case, and doesn't really
deserve any mention, not even at debug level.
It has bugged me for a while that we show the exact same welcome message
at boot twice: once in the initrd, and once after the initrd→host
transition. That's very confusing.
Let's change the text a bit, and tone down the initrd message a bit (by
removing the empty line before and after it), because it is the less
relevant one.
In previous commits, we've changed the JSON name mangling logic. This,
of course, will cause breaking changes to occur on anything that relied
on the JSON mangling logic.
This commit fixes those breaking changes by manually forcing the JSON
name back to what it was before.
First, when displaying JSON we convert dashes into underscores. We want
to avoid using dashes in JSON field names in new code, because some
JSON parsers don't support dashes very well.
Second, we make the first character of every word lower-case. This
better matches our JSON field name style, and makes the automatic
JSON name mangling a lot more useful for vertical tables, where fields
are given a display name. For example, "Foo Bar" would be converted into
"foo_bar" instead of "Foo_Bar", which much better matches our style.
We don't make the whole string lowercase to support cases like:
"fooBar" should stay as "fooBar".
Some situations don't behave quite perfectly, such as "Foo BarBaz" gets
converted into "foo_barBaz", or all-caps headings get mangled
incorrectly. In these situations, the JSON field should be overridden
manually. In most cases, or at least more cases than before, this
heuristic does good enough.
Lets you conveniently set JSON field names in table_add_many. Especially
useful for vertical tables. For example:
table_add_many(t,
TABLE_FIELD, "Display Name",
TABLE_STRING, obj->display_name,
TABLE_SET_JSON_FIELD_NAME, "displayName",
TABLE_FIELD, "Timestamp",
TABLE_TIMESTAMP, obj->timestamp,
TABLE_SET_JSON_FIELD_NAME, "timestampUSec");
We already have selinux=0 in the default kernel command line so
enforcing=0 is redundant. Instead, pass in enforcing=0 when we
enable selinux in TEST-06-SELINUX.
Previously, unit_freezer_new_freeze() would only return
UnitFreezer object if FreezeUnit() succeeds. This is not
ideal though, as a failed bus call doesn't mean the action
actually failed. E.g. a timeout might occur because pid1
is waiting for cgroup event from kernel, while the bus call
timeout was exceeded (#33269). In such a case, ThawUnit()
will never be called, resulting in frozen units remain that
way after resuming from sleep.
Therefore, let's get rid of unit_freezer_new_freeze(),
and make sure as long as unit freezer is involved, we'll
call ThawUnit() when we're done. This should make things
a lot more robust.
As per DPS the UUID for /var/ should be keyed by the local machine-id,
which is non-trivial to do in a script. Enhance 'systemd-id128' to
take 'var-partition-uuid' as a verb, and if so perform the
calculation.
In some cases userspace may need to create dmabuffers from userspace
on such example is the software ISP part of libcamera which needs to
allocate dma-buffers for the output of the software ISP.
At first the plan was to allow console users access to /dev/dma_heap/*,
this was discussed with various kernel folks here:
https://lore.kernel.org/all/bb372250-e8b8-4458-bc99-dd8365b06991@redhat.com/
Giving console users access to the dma_heap's was deemed a bad idea
because memory allocated this way is not accounted in cgroup limits.
Giving access to /dev/udmabuf OTOH was deemed acceptable so that
is what this patch adds.
Resolves: #32662
Prompted by #33737
The intention of b37e8184a5
is to expose sd_id128_get_app_specific() on command line.
But combining that with GPT type list makes little sense.
Same as the other aliases. Allows chaining commands like:
$ systemd-id128 show -P root-$(dpkg-architecture --query DEB_HOST_ARCH)

Let's make things a little more consistent and build the initrd
explicitly as a subimage as well instead of relying on mkosi building
it as part of the main image build.
We drop the opensuse initrd postinst script as we don't use erofs by
default anymore. We can always reintroduce it again later if needed.
Our usual rule is that we are more lenient towards misuse for public
users of our code than for ourselves. Or in other words: when validating
parameters of our public functions (those starting with sd_…) we prefer
assert_ret() over assert().
In C23 we can explicitly choose the integer type for an enum. Let's do
so to make our requirements for 64bit integers explicitly. Previously,
we'd rely on a GNU extension that would size the enum to 64bit if at
least one value outside the 32bit range is in the enum. Let's keep that
too, for compat with older compilers.
(Also, add the support for older compilers to the definition of
sd_json_dispatch_flags_t, where it was forgotten so far)
It's time. sd-json was already done earlier in this cycle, let's now
make sd-varlink public too.
This is mostly just a search/replace job of epical proportions.
I left some functions internal (mostly IDL handling), and I turned some
static inline calls into regular calls.
Let's make sure we don't load libnss_systemd.so from bash as the
necessary environment variables aren't set to make that work when
we're running with sanitizers enabled.
We can't add a sanitizer wrapper for bash as the wrapper runs using
bash so you end up in a loop.
We use -fdebug-prefix-map= because debugedit doesn't work for us (for
a currently unknown reason since it's the most obtuse code I've ever
had the pleasure of reading). With all the unique macros enabled, the
destination directory we pass to -fdebug-prefix-map= includes the package
release. The release is either the timestamp of the current commit or
the current time if the working tree is dirty. This means it generally
changes every time we rerun the build script. However, meson only reads
compiler arguments the first time it is invoked or if --wipe is specified.
This means that on a rerun -fdebug-prefix-map= will be configured wrong
and the build will fail.
Let's prevent this from happening by disabling the unique debug source
names by overriding the --unique-debug-src-base option that is passed to
find-debuginfo.sh by rpm via the _find_debuginfo_opts macro.
