2020-09-04session: Don't refuse unprivileged creation of "direct" backendPatrick Steinhardt
When starting a compositor that's using the "direct" session backend, wlroots needs to handle calls to `drmSetMaster()` and `drmDropMaster()`. As both calls used to require `CAP_SYS_ADMIN`, wlroots thus simply refused starting in case the process doesn't enjoy evelated privileges. Permission rules have changed since linux.git commit 45bc3d26c95a (drm: rework SET_MASTER and DROP_MASTER perm handling, 2020-03-19). As a result, starting with Linux v5.8, both ioctls will now also succeed if the process is currently or has been the DRM master. And as the first process to open render nodes will become the DRM master automatically, this effectively means that process elevation is not strictly required in all setups anymore. So let's drop the `geteuid() != 0` permission check to allow those new rules to do their magic.

(almost certainly due to systemd version <246)
2020-09-01backend/session/libseat: register log handlerSimon Ser
Route libseat errors through wlroots logging infrastructure. This requires libseat 0.2.0.
2020-08-26session: Add missing init to direct-freebsdKenny Levinsen
bad1e9afa8ea ("session: Add libseat backend") introduced a change to to how session backends initialize, but failed to update the FreeBSD specific version of the direct backend accordingly. Closes: https://github.com/swaywm/wlroots/issues/2376

2020-04-29Remove libcap supportScott Anderson
This is simply a false sense of security, and is worse than just using setuid. CAP_SYS_ADMIN is an extremely serious capability that is effectively as powerful as root. It also required users to be in the input group, which allows any process to keylog the entire system.
2020-04-15logind: Close fd before releasing deviceKenny Levinsen
This speeds up shutdown significantly, and is in line with how Weston does it.
2020-03-24build: Add 'auto' to logind-provider combo optionScott Moreau
The logind provider defaulted to systemd and in order to use elogind, -Dlogin-provider=elogind was required. This adds 'auto' as a choice for the login-provider option and sets it as default. Using 'auto', the build will check for systemd first and if it's not found, try to find and use elogind automatically.

2019-12-23meson: Various improvementsScott Anderson
Bumps minimum version to 0.51.0 - Remove all intermediate static libraries. They serve no purpose and are just add a bunch of boilerplate for managing dependencies and options. It's now managed as a list of files which are compiled into libwlroots directly. - Use install_subdir instead of installing headers individually. I've changed my mind since I did that. Listing them out is annoying as hell, and it's easy to forget to do it. - Add not_found_message for all of our optional dependencies that have a meson option. It gives some hints about what option to pass and what the optional dependency is for. - Move all backend subdirectories into their own meson.build. This keeps some of the backend-specific build logic (especially rdp and session) more neatly separated off. - Don't overlink example clients with code they're not using. This was done by merging the protocol dictionaries and setting some variables containing the code and client header file. Example clients now explicitly mention what extension protocols they want to link to. - Split compositor example logic from client example logic. - Minor formatting changes
2019-12-22backend/session/freebsd: Fix the way to get TTY pathTing-Wei Lan
Previously, the path of TTY is generated using snprintf with %d format. It works with TTY 1 to 10, but fails with TTY with greater number because the number used in the name is in base 32 instead of base 10. Since there is no standard function to convert a number to a string with a custom base, this commit adds a function to do it. Fixes: https://github.com/swaywm/wlroots/issues/1854
2019-11-03session/logind: Clean up add_signal_matchesScott Anderson
The original signal matching was using the old interface before sd_bus_match_signal was added, which the new code uses. Change them all to use it now.

2019-08-12backend/session: non-void function should return a valueAntonin Décimo
With assertions disabled, it should make sense to return NULL.
2019-07-27Remove all wayland-server.h includesSimon Ser
The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.
2019-05-22session/logind: check for XDG_SESSION_ID firstJan Chren
In order to support compositors running as systemd user units without display manager, a mechanism for specifying session ID exactly must exist. Checking for `XDG_SESSION_ID` mimics loginctl behaviour https://github.com/systemd/systemd/blob/e95be7def26c6c5feaf08a4135aa4f50c53263a8/src/login/loginctl.c#L856.
2019-05-22session/logind: specify seat exactlyJan Chren
"/org/freedesktop/login1/seat/self" path triggers seat-finding code path in logind, which currently relies on getting the session based on caller's PID. This behaviour is deprecated in logind as it doesn't work eg. with systemd user units, which run outside of user session. We check for "seat0" in logind_change_vt() already as introduced in 47985d2dc56a6af469ac9375e7548136765aff16, so hard-coding it here is not a problem, otherwise sd_session_get_seat() could be used.
2019-05-13session/logind: keep active for pause_device goneBrian Ashworth
This appears to be a quick fix for compositors freezing when a dock is disconnected. Disconnection of the dock is causing `pause_device` for the DRM devices associated with the dock. Since these devices major number is `DRM_MAJOR`, the session was being set to inactive. This just makes it so the session is not set to inactive when the device's state is `gone`.

2019-02-03Allow compositors to run as systemd user unitsmnussbaum
When a wlroots compositor runs as a systemd user unit there is no session associated with the compositor process. Instead we need to attach to an active and graphical user session. This change first looks for an available session for the process, and if there isn't one falls back to display in the oldest available graphical session. This work was modeled after a similar change to mutter - https://gitlab.gnome.org/GNOME/mutter/merge_requests/150.

2018-10-04Use sd_bus_get_property_trivial & remove numberingnyorain
2018-09-24Rework session handlingnyorain
Sessions can now be retrieved from a backend in a more general manner. Multi-backend gets back its `session` field that contains the session if one was created, removing the interfacing from multi backend with the drm backend directly. This adds the possibility to use sessions even without the drm backend. It additionally fixes the bug that 2 session objects got created when WLR_BACKENDS were set to "libinput,drm". To allow vt switching without drm backend (and drm fd) on logind, start listening to PropertiesChanged signals from dbus and parse the session "Active" property when no master fd was created (this does not change current drm backend behaviour in any way).

2018-09-07Implement device type discovery using ioctl callssghctoma
This commit implements device type discovery by calling two ioctls (DRM_IOCTL_VERSION and EVIOCGVERSION) on the device. These iocts are specific to drm and input devices respectively, therefore we can determine the device type based on which one returns an error.
2018-09-02Activate last active VT after compositor exitsghctoma
The VT the compositor was started from was not activated after exiting the compositor, which resulted in arriving on a blank VT. This commit fixes that by introducing a new field in direct_session struct that stores the last active VT so that it can be activated in direct_session_destroy.
2018-08-30Fix that major(st_rdev) have no meaning on FreeBSDsghctoma
The major device number does not indicate the device type on FreeBSD, and AFAIK the only way to differentiate between DRM, input, and other devices is checking the fd path. This commit implements that. The drmDropmaster and drmSetmaster calls are necessary, because the implicit drop (that should occur when the DRM fd is closed) seems not to be working in some scenarios (e.g. if you have a tmux session running - maybe the fd is retained somehow by tmux?). This is a problem, because once you exit the compositor, you can't start it (or any other program that wants to be DRM master) again until you close all your tmux sessions.

2018-08-08session: load GPU devices even if they have zero crtcs/connectors/encodersIlia Bozhinov
On some systems (most notably laptops with two GPUs) there are GPUs that don't have attached outputs. However, we still want to load those GPUs because they could still be used by the compositor for rendering.
