Manuel Stoeckl ded441ffd5 wlr_seat: Fix edge cases with serial validation 2019-06-30 15:01:05 -04:00
Manuel Stoeckl edb30a6828 Implement serial validation for selection requests
This change tracks, for each wlr_seat_client, the most recent serial
numbers which were sent to the client. When the client makes a
selection request, wlroots now verifies that the serial number
associated with the selection request was actually provided to that
specific client. This ensures that the client that was most
recently interacted with always has priority for its copy selection
requests, and that no other clients can incorrectly use a larger serial
value and "steal" the role of having the copy selection.

Also, the code used to determine when a given selection is superseded
by a newer request uses < instead of <= to allow clients to make
multiple selection requests with the same serial number and have the
last one hold.

To limit memory use, a ring buffer is used to store runs of sequential
serial numbers, and all serial numbers earlier than the start of the
ring buffer are assumed to be valid. Faking very old serials is
unlikely to be disruptive.

Assuming all clients are correctly written, the only additional
constraint which this patch should impose is that serial numbers
are now bound to seats: clients may not receive a serial number
from an input event on one seat and then use that to request
copy-selection on another seat.

Ilia Bozhinov fb739b8293 output-damage: set needs swap only when we have new damage
An output needs swap when there is new damage. If the damage is only
accumulated from the last frame, we could simply skip drawing.

Rouven Czerwinski d10072e76c backend: drm: switch to pageflip_handler_2
atomic and legacy now both pass the backend as the user data for the
pageflip event. We than retrieve the correct connector by matching on
the crtc_id passed to the page_flip_handler2.

Wlroots also requires the DRM_CRTC_IN_VBLANK_EVENT capability now.

Fixes #1297

Simon Ser ce3f4c3fe1 output: remove wlr_output_impl.transform
The backend doesn't need to handle transform changes, since everything is done
in software. In fact, all of the implementations were all identical and just
set the transform.

We could add support for hardware transforms, but:

- This would require a different field (something like hardware_transform)
- Not all combinations are possible because there often are hardware
  limitations
- The Wayland protocol isn't ready for this (in particular xdg-output, see [1])

This belongs to a different patch series anyway.

Simon Ser 33127c545b output: reset the pending state on failed commit
It can be surprising for callers to stash pending changes, commit, get a
failure, then set some other pending changes, commit again, and get another
failure because of the previously-pending changes.

Instead, make commit reset the pending state on failure.

Ashkan Kiani 06a13203dd Use a set to track pointer button state.
In addition to `button_count`, we keep track of the current buttons
pressed just as in `wlr_keyboard`.

Add `set_add` and `set_remove` to assist with this. These functions can
only be used with values greater than 0 (such as the button/key masks
for keyboards and pointers).

Partially addresses:

Rouven Czerwinski 96e9c0f9c8 drm: legacy: issue a NULL modeset on disable
The DRM subsystem needs a NULL modeset for connectors which disappear
from the system to disable the hardware pipes, otherwise the pixels get
rendered but are sent nowhere.

The atomic backend does the equivalent by removing the properties and
issuing a commit.

Brian Ashworth 6dfe238ff1 zwp_virtual-keyboard: fix mmap error handling
If mmap fails, it will return MAP_FAILED not NULL. Since the error
handling was incorrectly checking for NULL, MAP_FAILED was being passed
to xkb_keymap_new_from_string, on mmap failure, causing a segfault.
This just fixes the error checking.

Jan Chren 151b7d1d94 session/logind: check for XDG_SESSION_ID first
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 e95be7def2/src/login/loginctl.c (L856).

session/logind: specify seat exactly
"/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 47985d2dc5,
so hard-coding it here is not a problem, otherwise sd_session_get_seat() could be used.

Michiel a68c7c0c8d Fixes #1689 RDP RemoteFX crash
When using the rdp backend and connecting with xfreerdp ... --rfx, wlroots
crashes in backend/rdp/output.c while attempting to realloc(..., 0).

This commit guards against that and instead returns true, resulting in
no rfx message being sent. This prevents the crash and appears to work, but
it's not obvious if this is correct from a specification perspective.

Brian Ashworth 90c284bded session/logind: keep active for pause_device gone
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`.
