sysusers: add comments and simplify how set with names is created
The code was correct, but rather confusing: it used two sets with strings with
trivial_hash_ops to store strings used in other hashmaps. Let's add a bunch of
comments to explain what is happening. We also don't need two sets, using just
one saves a bit of memory.
While at it, let's add some debug messages if duplicate user/group names or
uids/gids are present.
This allows using it with CLEANUP_ARRAY(). For the 2 call sites
where we don't need to free the array, we do a regular for loop
calling json_variant_unref() instead.
We currently concatenate ANSI_UNDERLINE to the color of our choice
in DEFINE_ANSI_FUNC_UNDERLINE() and DEFINE_ANSI_FUNC_UNDERLINE_256().
The first thing that ANSI_UNDERLINE does is reset all previous ansi
escape sequences, so you just get underlining without any colors.
Let's fix the issue by actually concatenating _UNDERLINE to the given
color macro name so this works properly.
Also add missing color macros that this uncovered.
The mentioned change makes all jobs in the transaction unmergeable
if mode == JOB_RESTART_DEPENDENCIES, but we only want the anchor job
to be re-enqueued.
There were a couple spelling/grammatical errors in the docs that made
it hard to read and understand parts of this doc. I cleaned up those
errors and reflowed the line breaks to keep to the 80 char limit.
test: copy out the necessary test data before we start overmounting stuff
Otherwise the get_testdata_dir() call fails if the source tree is under
/root (which is usually the case in CIs).
I got bitten by this after leaving the source tree under /root but moving the
$BUILD_DIR elsewhere. This used to work by accident, as load_testdata_env()
would try to read $BUILD_DIR/systemd-runtest.env, but would fail if the
$BUILD_DIR is also under /root and fall back to SYSTEMD_TEST_DATA
(/lib/systemd/tests/testdata), which usually exist as we install the just built
revision. However, if the $BUILD_DIR is outside of /root we'd read
$BUILD_DIR/systemd-runtest.env which contains
SYSTEMD_TEST_DATA=/path/to/source/tree/test and that source tree is not visible
once we overmount /root with tmpfs making the test fail:
/* test_run_tests_unprivileged */

bus-unit-util: add common code for reloading PID 1
We have this very similar code in various places, and it#s not entirely
obvious (since we want a prolonged timeout for the reload), hence unify
this at one place.
When running from the build directory systemd-detect-virt might not be installed,
so tell meson to set up the PATH accordingly to point to the build directory.
So the multiple-machines tests run last to avoid a race where the
checked signal would get ignored while the stub init is still processing
the previous signals:
glibc does not provide clone() on ia64, only clone2. But only as a
symbol in the shared library, there's no prototype in the gblic
headers, so we have to define it, copied from the manpage.
st_dev is not the same as dev_t, and on O32 architectures like
mipsel it's an unsigned long, but dev_t is still unsigned long long,
so they don't match and compilation fails:
../src/journal/cat.c: In function ‘run’:

boot: Fix build for x32
When building on a x32 system we need to explicitly pass `-m64` to get
the right ABI as the kernel and EFI are still 64bit. For this to
actually work, a suitable multilib compiler, 32bit libc headers and
libgcc need to be installed (similar to ia32 builds on x86_64).
efi: skip libefitest if 'bootloader' is explicitly set to false
On x32 efi_arch will be set as the kernel architecture is just x86_64,
but there's no userland support to build the EFI ABI. When -Dbootloader=false
is set, skip libefitest too.
This syscall is for probing hardware capabilities from userspace and should do no harm.

fuzz: switch fuzz-manager-serialize to MANAGER_TEST_RUN_MINIMAL
When there is no access to cgroups MANAGER_TEST_RUN_BASIC will fail
to set up and assert. This happens on a build system like Debian's.
Switch to _MINIMAL which skips cgroup and other machine-wide setups.
meson: allow to fallback to use libxcrypt.pc or glibc's libcrypt
Some distributions still use glibc's libcrypt. In that case, libcrypt.pc
does not exist and dependency() will fail.
Also, even if libxcrypt is used, there may not be a symlink
from libcrypt.pc to libxcrypt.pc. So, let's add a secondary name.
When a static null address is requested, e.g. Address=0.0.0.0/24,
then the corresponding Address object owned by Network object has
null address, and previously it did not match any addresses already
assigne to the interface.
Let's search matching Address object when originally it is requested as
the null address.
Then, the address configured with requested as a null address will be
kept on reconfigure.
network: also use address_kernel_{hash,compare}_func() for managing address requests
Request may refer Address object owned by Link, but its broadcast
address or label may be updated by address_equalify(), hence these
fields cannot be used in the hash and compare functions.
