* udev: single binary replacing udevd and udevadmNorbert Lange2020-06-011-18/+4
| | | | | | | | | | | | | | | Since the separate binaries contain mostly the same code, this almost halves the size of the installation. before: 398K /bin/udevadm 391K /lib/systemd/systemd-udevd after: 431K /bin/udevadm 0 /lib/systemd/systemd-udevd -> ../../bin/udevadm Fixes: #14200
* xdg-autostart-generator: Add a generator for XDG autostart filesBenjamin Berg2020-05-271-0/+24
| | | | | | | | | | | | | | This generator can be used by desktop environments to launch autostart applications and services. The feature is an opt-in, triggered by xdg-desktop-autostart.target being activated. Also included is the new binary xdg-autostart-condition. This binary is used as an ExecCondition to test the OnlyShowIn and NotShowIn XDG desktop file keys. These need to be evaluated against the XDG_CURRENT_DESKTOP environment variable which may not be known at generation time. Co-authored-by: Henri Chain <henri.chain@enioka.com>
* dont install systemd-initctl, runlevel, telinit if no SYSV compatNorbert Lange2020-05-261-2/+3
| | | | systemd-initctl executable is still built.
* meson: add fuzz-tests= optionFrantisek Sumsal2020-05-211-3/+4
| | | | | | | | | The slow-tests= option already enables fuzzers as well, however, this option can't be used in the "fully sanitized" runs, as certain slow tests are affected by the performance quite significantly. This option allows us to enable only fuzzers without the slow tests to meet the needs of such runs.

* cryptsetup: split out key loading from pkcs11 code and teach search path logicLennart Poettering2020-05-191-1/+3
| | | | | Let's do some rearrangements, so that we can later on use this to automatically search for a key file.

* meson: initialize time-epoch to reproducible builds compatible valueDimitri John Ledkov2020-05-181-2/+7
| | | | | | | | | | | | | | | | | | | Debian Policy encourages to preserve timestamps whenever possible in the tarballs, thus stable release updates of systemd usually do not bump NEWS file timestamp. And thus time-epoch remains the same for the lifetime of a release. It would be better, if each new stable release rebuild of systemd would bump the time epoch a bit. But at the same time remain reproducible. SOURCE_DATE_EPOCH is an environmnet variable defined for this purpose. Thus if available, prefer that, instead of the NEWS file modification time. For example, on Debian/Ubuntu under the reproducible builds the SOURCE_DATE_EPOCH is set to the timestamp from the packaging metadata, thus it is incremented on every new stable release update, whilst preserving reproducible builds capability.

* shared/ethtool-util: hush gcc warnings about array boundsZbigniew Jędrzejewski-Szmek2020-05-111-0/+3

We can't fix that, so let's use a cast to avoid the warning. For https://github.com/systemd/systemd/issues/6119#issuecomment-626073743. v2: - use #pragma instead of a cast. It seems the cast only works in some cases, and gcc is "smart" enough to see beyond the cast. Unfortunately clang does not support this warning, so we need to do a config check whether to try to suppress.

|\ \ | |/ |/| tmpfiles: read /etc/passwd + /etc/group with fgetpwent()/fgetgrent() if --root= is specified
| * tmpfiles: optionally, read /etc/passwd + /etc/group without NSSLennart Poettering2020-05-071-0/+2
| | | | | | | | | | | | | | | | | | | | There are two libc APIs for accessing the user database: NSS/getpwuid(), and fgetpwent(). if we run in --root= mode (i.e. "offline" mode), let's use the latter. Otherwise the former. This means tmpfiles can use the database included in the root environment for chowning, which is a lot more appropriate. Fixes: #14806
* | Add a basic test that the configured fallback hostname is OKZbigniew Jędrzejewski-Szmek2020-05-071-1/+8
| | | | | | | | | | | | | | | | Ideally, assert_cc() would be used for this, so that it is not possible to even compile systemd with something like '-Dfallback-hostname=.foo'. But to do a proper check we need to call hostname_is_valid(), and we cannot depend on being able to run code (e.g. during cross-compilation). So let's do a very superficial check in meson, and a proper on in test-util.
* | meson: drop "meson-" prefix from various helper script filenamesZbigniew Jędrzejewski-Szmek2020-05-071-9/+9
|/ | | | | | | | | | | In a few cases, the prefix was originally necessary because a different helper script was used for automake, and a different one for meson. But now we use meson exclusively, and the prefix isn't useful. This also synchronizes the target name, file name, and variable name in meson.build. The targets exposed by meson didn't have the prefix, so the user interface is unchanged. (The prefix is retained in the few tools that are used for meson itself, e.g. meosn-vcs-tag.sh, meson-make-symlink.sh, etc.)
