2021-08-15libseat: Fix build of builtin backendKenny Levinsen
This was regressed by 166feaea3394e00af14418e074ae090e31922f33 which missed the builtin backend when changing struct libseat_seat_listener to being passed around as const.
2021-08-15libseat: Update builtin backend root requirement documentationGreg Depoire--Ferrer
The builtin backend no longer requires root, setuid or CAP_SYS_ADMIN. This commit updates the documentation accordingly.
2021-08-15Revert "libseat: Check euid before using builtin"Greg Depoire--Ferrer
This reverts commit 1ae6c3b3ddf0ce2a2e1817eb9c74e0c03153df58. A user might want to run the builtin server as non root, if they have permission to use the devices. The check was originally copied from wlroots's direct backend. It was reverted in fa05d3cde68d with a detailed explanation of why root priviledges are not always necessary to use the DRM device.
2021-08-15logind: Remove redundant null checkKenny Levinsen
2021-08-15Make libseat_seat_listener constSimon Ser
libseat will never write to that struct. Let's allow callers to make it read-only.
2021-08-08seatd: Use path in chmod/chown operationsKenny Levinsen
c8b3a22d4ef0f69c3d22f0ec1170b89c93ef1dc3 snuck in a change which converts chown/chmod to fchown/fchmod using the socket fd. This appears to succeed under Linux, but fails with EINVAL on FreeBSD. As the error handling in this area was flawed, CI failed to catch the regression. Partially revert c8b3a22d4ef0f69c3d22f0ec1170b89c93ef1dc3 to fix the regression on FreeBSD.
2021-08-08seatd: Improve socket permission error handlingKenny Levinsen
chmod/chown errors were logged, but did not result in failure opening the seatd socket. This meant that errors would not get caught by CI.

2021-08-06seatd-launch: check for getpwuid errorsSimon Ser
2021-08-06seatd-launch: don't use gotos in child processesSimon Ser
While forked (child pid is zero), don't use gotos. These will execute atexit functions and potentially mess up the stdlib. Instead, use _exit.
2021-08-06seatd-launch: propagate child exit statusSimon Ser
When the child process exits with a non-zero code or is killed, return with a non-zero code as well.

2021-08-06ci: Use seatd-launchKenny Levinsen
2021-08-06seatd-launch: Add seatd launch wrapperKenny Levinsen
This launch wrapper is used to conveniently start a new seatd instance, wait for it to be ready, and launch a target application.
2021-08-06seatd: Only set UID/GID when specifiedKenny Levinsen
The UID/GID defaulted to 0, which results in trying to chown to root when a UID or GID isn't requested. Instead, deafult to -1 so that the unspecified values are left intact.
2021-08-06seatd: s6-style readiness notification supportKenny Levinsen
This adds the ability to specify the number of an fd that is inherited by the process as open. Once seatd is read to serve requests, it will write a single newline and close the fd.
2021-08-06seatd: We shouldn't poll if predispatch > 0Kenny Levinsen
This condition was accidentally botched as part of 5923e0edc9bb157cf6398b63d51cc3c0aaf06001
2021-07-09libseat: Rename dispatch_background in backendsKenny Levinsen
This name never made much sense. dispatch_and_execute is more meaningful, especially when compared to the non-executing dispatch function.
2021-07-09libseat/seatd: Add dispatch_pending_and_executeKenny Levinsen
This handler returns the number of dispatched or executed events, or -1 if dispatch_pending failed. This helper is used to clean up dispatch_background, which now ensures that all events are executed before we read or poll the connection, and have improved error handling in the corner case where the second dispatch_pending failed.
2021-07-08libseat/seatd: Return executed eventsKenny Levinsen
Dispatch needs to report if something has happened, which includes events executed from the queue as these could have lead to additional dispatch and queuing.
2021-07-06build: add prefix to libseat optionsSimon Ser
The option names are a little bit confusing, because it's not clear which ones toggle libseat features, and which ones toggle seatd features. Add a "libseat-" prefix to libseat-specific features, to make it more obvious that they only are about the library.
2021-06-20link with rtSimeon Schaub
Since seatd uses `clock_gettime`, this is needed when cross-compiling. This came up in https://github.com/JuliaPackaging/Yggdrasil/pull/3193.
2021-05-19readme: Update discuss sectionKenny Levinsen
2021-04-25meson: Support building builtin without seatdKenny Levinsen
The builtin backend relies on the seatd backend implementation. When builtin was enabled without seatd, compilation would fail due to the implementation not being included. Include the implementation if either seatd or builtin is enabled.
2021-04-25libseat/seatd: downgrade ENOENT log to infoSimon Ser
The socket is expected not to be found if seatd is not running. In general other backends will be attempted after seatd. There is already an error message in case no backend can be started.
2021-04-17contrib/systemd: Use a different groupKenny Levinsen
"video" was used for convenience in the example, but a dedicated group is preferable so that a user does not gain the ability to bypass the seat manager and open devices directly.
2021-04-10build: set pkgconfig/dependency variables for featuresSimon Ser
This allows libseat users to e.g. advise people to chmod a+s the executable if libseat is built with the builtin backend. While bumping the Meson version, adjust the scdoc logic to avoid the following warnings: WARNING: Project targeting '>=0.56.0' but tried to use feature deprecated since '0.56.0': Dependency.get_pkgconfig_variable. use Dependency.get_variable(pkgconfig : ...) instead WARNING: Project targeting '>=0.56.0' but tried to use feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
2021-04-10build: disable logind on -Dauto_features=disabled -Dlogind=autoSimon Ser
Setting auto_features=disabled is supposed to disable all optional dependencies. Since we aren't using a feature option here, we need to manually add logic to disable logind in this case.
2021-04-08build: don't allow "auto" for seatd, builtin, server and examplesSimon Ser
These features don't have any dependencies, so "auto" doesn't make sense.
2021-04-08build: don't explicitly search for shSimon Ser
This removes the "Program sh found" line in the build logs, and should not change anything else.
2021-04-08build: fix logind feature summary when auto-detectedSimon Ser
If -Dlogind=auto but systemd/elogind isn't available, logind_provider would get set to the last item of the foreach loop. This would incorrectly report "systemd: YES".
2021-04-08build: add explicit logind provider option, auto-detect by defaultSimon Ser
Allow package maintainers to explicitly select a logind provider by passing -Dlogind=systemd or -Dlogind=elogind. In case both are available (e.g. for distributions which support both), this makes it possible to gte deterministic behavior. By default, auto-detect the logind provider. That way, users which have systemd or elogind installed get the backend built by default.
2021-04-08meson: make 'logind' var always availableKenny Levinsen
2021-04-08ci: Use 'auto' for arch linux logindKenny Levinsen
2021-03-26Avoid a clang-format quirkKenny Levinsen
clang-format wants to put the terminating NULLs on the same line as the noop backend when it doens't have any immediate non-NULL neighbors. Add a newline to stop it.
2021-03-26meson: declare libseat dependencySimon Ser
This can be used by parent projects when seatd is a subproject: libseat = dependency('libseat', fallback: ['seatd', 'libseat'])
2021-03-26Add no-op sessionSimon Ser
This is useful for headless testing, for instance with VKMS: modprobe vkms export WLR_DRM_DEVICES=/dev/dri/card1 export WLR_BACKENDS=drm export LIBSEAT_BACKEND=noop sway We don't need any of the VT handling in this case.
