* shared: split out crypt() specific helpers into its own .c/.h in src/shared/Lennart Poettering2020-01-151-0/+7
| | | | | | | | | | This way we can use libxcrypt specific functionality such as crypt_gensalt() and thus take benefit of the newer algorithms libxcrypt implements. (Also adds support for a new env var $SYSTEMD_CRYPT_PREFIX which may be used to select the hash algorithm to use for libxcrypt.) Also, let's move the weird crypt.h inclusion into libcrypt.h so that there's a single place for it.

* Rename "system-options" to "systemd-efi-options"Zbigniew Jędrzejewski-Szmek2019-11-181-2/+2
| | | | | | | | | | | | | | | | This makes the naming more consistent: we now have bootctl systemd-efi-options, $SYSTEMD_EFI_OPTIONS and the SystemdOptions EFI variable. (SystemdEFIOptions would be redundant, because it is only used in the context of efivars, and users don't interact with that name directly.) bootctl is adjusted to use 2sp indentation, similarly to systemctl and other programs. Remove the prefix with the old name from 'bootctl systemd-efi-options' output, since it's redundant and we don't want the old name anyway.

| * Add support for SystemdOptions EFI var to augment /proc/cmdlineZbigniew Jędrzejewski-Szmek2019-09-161-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | In various circumstances, overriding the kernel commandline can be inconvenient. People have different bootloaders, and e.g. the grub config can be pretty scary. grubby helps, but it isn't always available. This option adds an alternative mechanism that can quite convenient on EFI systems. cmdline settings have higher priority, because they can be (usually) changed on the bootloader prompt. $SYSTEMD_EFI_OPTIONS can be used to override, same as $SYSTEMD_PROC_CMDLINE.
* | nspawn: rename UNIFIED_CGROUP_HIERARCHY to SYSTEMD_NSPAWN_UNIFIED_HIERARCHYZbigniew Jędrzejewski-Szmek2019-10-011-2/+2
|/ | | | | | | | | | | | | | | We should never have used an unprefixed environment variable name. All other systemd-nspawn variables have the "SYSTEMD_NSPAWN_" prefix, and all other systemd variables have the "SYSTEMD_" prefix. The new variable name takes precedence, but we fall back to checking the old one. If only the old one is found, a warning is emitted. In addition, SYSTEMD_NSPAWN_UNIFIED_HIERARCHY="" is accepted as an override to avoid looking for the old variable name. We have a variable with the same name ($UNIFIED_CGROUP_HIERARCHY) in tests, which governs both systemd-nspawn and qemu behaviour. It is not renamed.
* locale-util: suppress non-UTF-8 locales when enumerating themLennart Poettering2019-07-141-0/+6
| | | | | | | | | | | | | | Let's hide non-UTF-8 locales by default. It's 2019 after all. Let's add an undocumented env var to reenable listing them though. This should substantially shorten the list of choices we offer users, and only show realistic choices. note that only firstboot and localectl make use of this information, and both allow configuration of values outside of these lists, hence all this change does is hide legacy options, but they are still available if you know what you do, and that's how it should be.

* docs: add a "front matter" snippet to our markdown pagesFilipe Brandenburger2019-01-021-0/+4
| | | | | | | | | | | | | | | | It turns out Jekyll (the engine behind GitHub Pages) requires that pages include a "Front Matter" snippet of YAML at the top for proper rendering. Omitting it will still render the pages, but including it opens up new possibilities, such as using a {% for %} loop to generate index.md instead of requiring a separate script. I'm hoping this will also fix the issue with some of the pages (notably CODE_OF_CONDUCT.html) not being available under systemd.io Tested locally by rendering the website with Jekyll. Before this change, the *.md files were kept unchanged (so not sure how that even works?!), after this commit, proper *.html files were generated from it.

* meson: make net.naming-scheme= default configurableZbigniew Jędrzejewski-Szmek2018-12-121-7/+8
| | | | | | | | | | | | | | | | This is useful for distributions, where the stability of interface names should be preseved after an upgrade of systemd. So when some specific release of the distro is made available, systemd defaults to the latest & greatest naming scheme, and subsequent updates set the same default. This default may still be overriden through the kernel and env var options. A special value "latest" is also allowed. Without a specific name, it is harder to verride from meson. In case of 'combo' options, meson reads the default during the initial configuration, and "remembers" this choice. When systemd is updated, old build/ directories could keep the old default, which would be annoying. Hence, "latest" is introduced to make it explicit, yet follow the upstream. This is actually useful for the user too, because it may be used as an override, without having to actually specify a version.
* udev: introduce udev net_id "naming schemes"Lennart Poettering2018-12-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | With this we can stabilize how naming works for network interfaces. A user can request through a kernel cmdline option or an env var which scheme to follow. The idea is that installers use this to set into stone (a very soft stone though) the scheme used during installation so that interface naming doesn't change afterwards anymore. Why use env vars and kernel cmdline options, and not a config file of its own? Well, first of all there's no obvious existing one to use. But more importantly: I have the feeling that this logic is kind of an incomplete hack, and I simply don't want to do advertise this as a perfectly working solution. So far we used env vars for the non-so-official options and proper config files for the official stuff. Given how incomplete this logic is (i.e. the big variable for naming remains the kernel, which might expose sysfs attributes in newer versions that we check for and didn't exist in older versions — and other problems like this), I am simply not confident in giving this first-class exposure in a primary configuration file.

* sulogin-shell: Use force if SYSTEMD_SULOGIN_FORCE setAndreas Henriksson2018-10-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | When the root account is locked sulogin will either inform you of this and not allow you in or if --force is used it will hand you passwordless root (if using a recent enough version of util-linux). Not being allowed a shell is ofcourse inconvenient, but at the same time handing out passwordless root unconditionally is probably not a good idea everywhere. This patch thus allows to control which behaviour you want by setting the SYSTEMD_SULOGIN_FORCE environment variable to true or false to control the behaviour, eg. via adding this to 'systemctl edit rescue.service' (or emergency.service): [Service] Environment=SYSTEMD_SULOGIN_FORCE=1 Distributions who used locked root accounts and want the passwordless behaviour could thus simply drop in the override file in /etc/systemd/system/rescue.service.d/override.conf Fixes: #7115 Addresses: https://bugs.debian.org/802211

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.
