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.

Route libseat errors through wlroots logging infrastructure.
This requires libseat 0.2.0.

Without the casts the bytes accesses get converted to int. but int is
not guaranteed to be 4 bytes large. Even when it is 4 bytes large
`bytes[3] << 24` does not fit because int is signed.
|
|
This type is meant to be 4 bytes large as seen in _XcursorReadUInt which
always reads 4 bytes. An unsigned int is often 4 bytes large but this
isnt' guaranteed so it is cleaner to use the exact type we want.

This example was relying on wl_display_dispatch being enough to fetch
output information. This worked by chance.
Add an explicit wl_display_roundtrip.
Other examples don't setup wl_output listeners, so they should be fine.

This event contains a `committed` bitfield, which allows callers to know
which output fields changed during the commit.
This allows users to setup a single atomic commit listener, instead of
setting up one listener for each event (mode, scale, transform, and so
on).

Don't force compositors to check when an empty shape is being renderered.
References #2282. This was motivated by dwl crashing when setting window
borders to 0 (djpohly/dwl#51).

These states are distinct in the time period between the ack_configure
and the next commit on the surface. Splitting these states avoids the
following race for example:
- client starts at 1000x1000
- wlr_xdg_toplevel_set_size 500x500
- size is different -> configure sent
- client acks the configure
- wlr_xdg_toplevel_set_size 1000x1000
- compare_xdg_toplevel_state returns true since there is no pending
configure and the currently committed size is still 1000x1000
- no new configure is sent
- client commits at the size it last acked, 500x500

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.

wl_display_roundtrip already takes care of dispatching the display.

gamma_control_send_failed destroys gamma_control.

get_drm_prop_blob does not set path_len if it returns NULL. Check the
return value before path_len to avoid reading uninitialized memory.
(Granted, this doesn't change the logic at all, but it does make
Valgrind a bit happier.)

Move the global into wlr_gles2_renderer. This removes global state and
allows us to have multiple renderers with different GL loaders.
|
|
|
|
|
|
These functions are unused by compositors (see e.g. [1]) and prevent
wlr_gles2_texture from accessing wlr_gles2_renderer state. This is an
issue for proper teardown [2] and for accessing GLES2 extensions.

Certain clients require this property to be set for expected behavior.
Most notably, steam client CSD maximize button no longer worked
after unmaximizing once, unless the state was changed by another
method. The state is unset whenever another surface gains focus.

This avoids uninitialized items and makes it clear where the magic
number 2 is coming from.

This helps mitigate buffer overflows.

In case wl_event_loop_add_timer errors out, don't insert the free'd

It allows a compositor to do things like skip motion events on pointer
constraint unlock.

eglGetCurrentDisplay() returns EGL_NO_DISPLAY when there is no context current
and eglMakeCurrent() needs a display argument.

drm_connector_set_cursor wasn't checking the return value of the
drm_surface_make_current call. On failure, this results in a failed
assertion in wlr_renderer_begin (because no rendering context is
current).

This was rendered useless in 5cde359.
