This simplifies get_testdata_dir() to simply checking for an environment
variable, with an additional function to locate a systemd-runtest.env file in
the same directory as the test binary and reading environment variable
assignments from that file if it exists.
This makes it possible to:
- Run `ninja test` from the build dir and have it use ${srcdir}/test for
test unit definitions.
- Run a test directly, such as `build/test-execute` and have it locate
them correctly.
- Run installed tests (from systemd-tests package) and locate the test
units in the installed location (/usr/lib/systemd/tests/testdata), in
which case the absence of the systemd-runtest.env file will have
get_testdata_dir() use the installed location hardcoded into the
binaries.
Explicit setting of $SYSTEMD_TEST_DATA still overrides the contents of
systemd-runtest.env.
An assertion in dhcp_network_bind_raw_socket() is triggered when
starting an sd_dhcp_client without setting a MAC address first.
- sd_dhcp_client_start()
- client_start()
- client_start_delayed()
- dhcp_network_bind_raw_socket()
In that case, the arp-type and MAC address is still unset. Note that
dhcp_network_bind_raw_socket() already checks for a valid arp-type
and MAC address below, so we should just gracefully return -EINVAL.
Maybe sd_dhcp_client_start() should fail earlier when starting without
MAC address. But the failure here will be correctly propagated and
the start aborted.

When a network namespace is needed, /sys is mounted as tmpfs (see commit
d8fc6a000f for details).
But in this case mode 755 was used as initial permissions for /sys whereas the
default mode for sysfs is 555.
In practice using 755 doesn't have any impact because /sys is mounted read-only
too but for consistency, let's use the correct mode.

Starting with meson 0.46, it is able to detect these argument correctly.
See this commit in meson codebase for more details:
695b8f3a03
We already carry a requirement for meson_version : '>= 0.46', so we can be sure
our build system will include this commit.
Tested by building systemd using a cloned meson synced to the 0.46.0 tag,
confirmed the warnings were detected correctly in that case. The meson messages included this snippet:
> Compiler for C supports arguments -Wno-unused-parameter -Wunused-parameter: YES
> Compiler for C supports arguments -Wno-missing-field-initializers -Wmissing-field-initializers: YES
> Compiler for C supports arguments -Wno-unused-result -Wunused-result: YES
> Compiler for C supports arguments -Wno-format-signedness -Wformat-signedness: YES
> Compiler for C supports arguments -Wno-error=nonnull -Werror=nonnull: YES
> Compiler for C supports arguments -Wno-maybe-uninitialized -Wmaybe-uninitialized: YES
Add accelerometer orientation quirk for the Chuwi Vi10 (CWI505) tablet.
While at it also update the Chuwi Hi8 Pri comment to include the
CWI model-number.
The GitHub guide on contributing file says: "Decide whether to store your
contributing guidelines in your repository's root, docs, or .github directory."

But there's really no advantage to keeping it in the hidden .github/, since
these are public and really belong together with the other documentation.
We can still keep the issue templates under .github/, since they are not really
documentation on their own.
Updated the links pointing to CONTRIBUTING.md to refer to the one in docs/.
The docs/ directory is special in GitHub, since it can be used to serve GitHub
Pages from, so there's a benefit to switching to it in order to expose it
directly as a website.
Updated references to it from the documentations themselves, from the
CONTRIBUTING.md file and from Meson build files.
Compiler flag -Wmaybe-uninitialized is quite noisy and produces many false
positives, especially when optimization flags are enabled (tested gcc 8.2.1),
so let's just disable it in systemd build.
For example, with CFLAGS=-O2, the build produces 11 such warnings and the
default CFLAGS of Fedora's rpmbuild warns about it in 176 places. A look at a
sample of those shows that most are false positives, where the compiler just
can't figure it out correctly. (While fixing those would be nice, I'm not sure
it's a good use of our time.)
The noisy [-Wmaybe-uninitialized] warnings are not just an annoyance, since
they make it harder to spot warnings that indicate actual problems (such as
variable declared but not used.) Silencing those is beneficial, so that
contributors would see warnings where there are actually actionable problems,
so there's a better chance of having those issues addressed before a PR is
pushed.
Tested:
$ CFLAGS='-O2 -Wp,-D_FORTIFY_SOURCE=2' meson build/
$ ninja -C build/
(NOTE: -Wp,-D_FORTIFY_SOURCE=2 prevents [-Wstringop-truncation] warnings.)
With the commands above, the build will not produce any [-Wmaybe-uninitialized]
warnings (or any other warnings), which is not really the case before this commit.
Also tested with rpmbuild on Fedora, after this commit there are no warnings
produced in the build step.
If more than one errno is specified for a syscall in SystemCallFilter=,
use the last one instead of reporting an error. This is especially
useful when used with system call sets:
SystemCallFilter=@privileged:EPERM @reboot
This will block any system call requiring super-user capabilities with
EPERM, except for attempts to reboot the system, which will immediately
terminate the process. (@reboot is included in @privileged.)
This also effectively fixes#9939, since specifying different errnos for
“the same syscall” (same pseudo syscall number) is no longer an error.
Dracut has a support for unlocking encrypted drives with keyfile stored
on the external drive. This support is included in the generated initrd
only if systemd module is not included.
When systemd is used in initrd then attachment of encrypted drives is
handled by systemd-cryptsetup tools. Our generator has support for
keyfile, however, it didn't support keyfile on the external block
device (keydev).
This commit introduces basic keydev support. Keydev can be specified per
luks.uuid on the kernel command line. Keydev is automatically mounted
during boot and we look for keyfile in the keydev
mountpoint (i.e. keyfile path is prefixed with the keydev mount point
path). After crypt device is attached we automatically unmount
where keyfile resides.
Example:
rd.luks.key=70bc876b-f627-4038-9049-3080d79d2165=/key:LABEL=KEYDEV
According to RFC2616[1], HTTP header names are case-insensitive. So
it's totally valid to have a header starting with either `Date:` or
`date:`.
However, when systemd-importd pulls an image from an HTTP server, it
parses HTTP headers by comparing header names as-is, without any
conversion. That causes failures when some HTTP servers return headers
with different combinations of upper-/lower-cases.
An example:
https://alpha.release.flatcar-linux.net/amd64-usr/current/flatcar_developer_container.bin.bz2 returns `Etag: "pe89so9oir60"`,
while https://alpha.release.core-os.net/amd64-usr/current/coreos_developer_container.bin.bz2
returns `ETag: "f03372edea9a1e7232e282c346099857"`.
Since systemd-importd expects to see `ETag`, the etag for the Container Linux image
is correctly interpreted as a part of the hidden file name.
However, it cannot parse etag for Flatcar Linux, so the etag the Flatcar Linux image
is not appended to the hidden file name.
```
$ sudo ls -al /var/lib/machines/
-r--r--r-- 1 root root 3303014400 Aug 21 20:07 '.raw-https:\x2f\x2falpha\x2erelease\x2ecore-os\x2enet\x2famd64-usr\x2fcurrent\x2fcoreos_developer_container\x2ebin\x2ebz2.\x22f03372edea9a1e7232e282c346099857\x22.raw'
-r--r--r-- 1 root root 3303014400 Aug 17 06:15 '.raw-https:\x2f\x2falpha\x2erelease\x2eflatcar-linux\x2enet\x2famd64-usr\x2fcurrent\x2fflatcar_developer_container\x2ebin\x2ebz2.raw'
```
As a result, when the Flatcar image is removed and downloaded again,
systemd-importd is not able to determine if the file has been already
downloaded, so it always download it again. Then it fails to rename it
to an expected name, because there's already a hidden file.
To fix this issue, let's introduce a new helper function
`memory_startswith_no_case()`, which compares memory regions in a
case-insensitive way. Use this function in `curl_header_strdup()`.

On Dell machines LoadOptions is filled with:
01 00 00 00 <name of BIOS Boot Loader Entry> ... <unknown bytes>
So, in case of meaningfull LoadOptions, better check if the first char
is a printable character.
Fix#9993. When this code was split out to user-runtime-dir, it forgot to
include the call to mac_selinux_init(). So mkdir_label() stopped working.
