[PATCH v3 00/14] drm/panic: Split into core and helpers

[PATCH v3 00/14] drm/panic: Split into core and helpers

[Thomas Zimmermann]

Split DRM's current panic handling into a core and a helper module.
The core is still part of DRM's core library. The panic helpers are
part of DRM's KMS helper module (for now).

The motivation behind this series is to get panic handling's drawing
code out of the DRM core. At some point it should share a single
module with DRM's other drawing and format conversion.

With the series applied, panic handling follows DRM's established
design pattern of having a DRM core interface with a dedicated
implementation in each driver. Drivers share common code in helper
modules. For panic handling, the DRM core still contains the panic
entry points, the parameters and the debugfs interface. All drawing
is now located in the panic helpers.

Patches 1 to 4 improve several issues in the current panic code. It
makes sense to fix them before moving the core around.

Patches 5 to 8 put handling of all panic state and locking into a
single place, drm_panic_display_panic_screen(). It is maintained by
panic handling's DRM core code. This also enables the test cases to
work more independently from the kernel's configuration.

Patches 9 to 13 split the panic-handling code into the core and panic
helpers. The former maintains all state, locking and public interfaces.
The latter handles drawing and details of the involved framebuffers.

DRM devices that offer panic handling provide a single callback, struct
drm_plane_funcs.display_panic_screen. A new initializer macro makes it
point to the existing panic-drawing implementation. Hence there's no
change in features or functionality. If panic handling is configured
off, it all clears out to NULL.

Patch 14 reworks the test cases slighly, so that they can be build as
a separate module. Do 'modprobe drm_panic_helper_test' to run them.

Tested under bochs, i915, amdgpu with debugfs and test cases.

Future directions:

- Panic handling shares drawing code with format conversion and
clients. There's even more drawing code in vkms. Later series' can
attempt to unify and harmonize all these implementations in a single
draw module.

- The drawing helper drm_plane_helper_display_panic_screen() still
implements various access schemes (map, set_pixel, memcpy) in a single
function. It could be split up into specialized helpers.

- If we ever need a driver-specific helper, it is now possible to
implement a custom version of display_panic_screen.

v3:
- keep qrbuf allocation as-is (Jocelyn)
- handle kmap failures gracefully
- handle unescaped URL strings correctly
- fix per-plane panic testing
- clean up after test cases
v2:
- resolve the various Kconfig issues (Randy)
- remove changes to qrbuf allocation (Jocelyn, Geert)
- fix possible URL format-string attack
- make test cases work again uder certain edge cases
- add better error reporting from failed draw_screen
- filter out non-primary planes from panic handling

[PATCH v3 01/14] drm/panic: Do not use un-escaped URL as format string

[Thomas Zimmermann]

Replace the direct use of DRM_PANIC_SCREEN_QR_CODE_URL in snprintf()
with a %s conversion specifier. Avoids a possible vulnerabilty from
a crafted URL string.

As the attacker needs to control the kernel at the Kconfig level, the
potential for an exploit is likely low.

[Thomas Zimmermann]

Do nothing if kmap_local_page_try_from_panic() returns NULL. This is
not likely to hapen, as the previous page from the same memory area
has been mapped successfully.

[PATCH v3 03/14] drm/panic: Return -EINVAL if font is not available

[Thomas Zimmermann]

Font lookup does not allocate memory. Hence reporting ENOMEM on
failed lookups is misleading. Report EINVAL instead.

[PATCH v3 04/14] drm/panic: Return errno codes if panic output fails

[Thomas Zimmermann]

Return errno codes from the panic output helpers to detect invalid
panic handling. Avoid flushing the display if an error ocured. The
unflushed display output might be helpful in debugging.

For now, test the result values in the panic test cases. A later patch
will add support for retrying failed panic output.

v2:
- forward return value of draw_panic_screen_user() (Sashiko)
- forward errno code from drm_panic_get_qr_code

[PATCH v3 05/14] drm/panic: Pass colors to draw_panic_dispatch()

[Thomas Zimmermann]

Set the panic-screen colors in draw_panic_plane() as a single point
of truth. Pass the values into the individual drawing functions.

In the test cases, replace the Kconfig-defined colors with white and
black. Allows for removal of the tests' limitations and dependency on
the exact values. All tests now always verify the generated output.

Hardcoding the test colors will later also allow for building the
test case without having DRM panic handling enabled.

[PATCH v3 06/14] drm/panic: Pass global module parameters to drm_panic_dispatch()

[Thomas Zimmermann]

Set the panic type and QR version in draw_panic_plane() as a single
point of truth. Pass the values into the individual drawing functions.

In the test case, always create a QR code with version 40 (i.e., the
highest supported version).

[PATCH v3 07/14] drm/panic: Return from screen_user if display is too small

[Thomas Zimmermann]

Return an error if the display is too small to display at least a
single character. If the panic handler cannot display any message
it does at least not destroy the current output, which might help
with identifying the problem.

This change duplicates the logic from screen_kmsg output.

[PATCH v3 08/14] drm/panic: Retry in dispatch function if panic output fails

[Thomas Zimmermann]

On failed output of QR codes and kmsg buffers, fall back to a user
message. QR-code output already did this internally, but now formally
support it in drm_panic_dispatch(). Streamlines the existing logic.

With the implicit fallback removed from QR-code support, the tests
cases fail for thr smallest output size (300x200). This is because the
QR code requires a minimal output size. Increase the size to 494x494,
which is the minimum supported size for QR output.

v3:
- update outdated commit description (Sashiko)
v2:
- fix minimum test size (Sashiko)

[PATCH v3 09/14] drm/panic: Split draw_panic_plane()

[Thomas Zimmermann]

Move locking and parameters from draw_panic_plane() into the new
helper drm_panic_display_panic_screen(). Call draw_panic_plane() from
there.

The new helper drm_panic_display_panic_screen() is now the DRM core's
interface for displaying a panic screen. The code remaining in
draw_panic_plane() still does all the heavy lifting. It will become a
plane helper for DRM drivers.

v2:
- use panic_type argument in draw_panic_plane() (Sashiko)

[PATCH v3 10/14] drm/panic: Restrict to primary planes

[Thomas Zimmermann]

Restrict panic handling to primary displays. Overlays and cursors
should not display panic output. If there are exceptions, they can
be registered by the driver itself.

v3:
- also update drm_panic_is_enabled() (Sashiko)
- still do some testing when unregistering (Sashiko)

[PATCH v3 11/14] drm/panic: Display panic screen via per-plane callback

[Thomas Zimmermann]

Add display_panic_screen to struct drm_plane_funcs. If set on a plane,
register a panic handler for the plane from the DRM core's panic
handling. Invoke this helper from the core to display a panic screen.

The new callback replaces get_scanout_buffer as signal for panic
support in a plane. Using get_scanout_buffer is now merely a detail
of the implementation. This will also free struct drm_scanout_buffer
for use cases besides panic handling.

With display_panic_screen in place, rename draw_panic_plane() to
drm_plane_helper_display_panic_screen() and make it available to DRM
drivers via drm_panic_helper.h. Do not change the implementation or
functionality of this code. drm_plane_helper_display_panic_screen()
still supports kernel messages, user messages and QR codes on various
color formats.

Then update all drivers that implement panic support. Provide the
initializer macro DRM_PANIC_PLANE_FUNCS that sets display_panic_screen
to drm_plane_helper_display_panic_screen(). If panic handling has
been disabled, it instead clears the callback. There's again no change
in functionality.

This logically splits panic handling into a set of entry points in the
DRM code and a set of helper functions provided by drivers. The core
invokes the driver's helper via callback, while the driver can tailor
the implementation to its needs. Panic handling now works like most
other interfaces in the DRM framework.

Locking and state-handling happens in the DRM core or helpers. Drivers
that receive a call to display_panic_screen can assume that no concurrent
modeset takes place on the plane or its CRTC.

Also update the documentation. Move information about locking and state
guarantees from drm_panic_trylock() to display_panic_screen, where
drivers authors can find it easily. Move information about the features
of the current implementation to drm_panic_helper_display_panic_screen().

v2:
- only consider planes with get_scanout_buffer (Sashiko)
- set callback for planes create with drm_crtc_init() (Sashiko)
- return errno code from display_panic_screen

[PATCH v3 12/14] drm/panic: Internalize panic locking in DRM core and helpers

[Thomas Zimmermann]

None of the DRM drivers handles panic locking. Declare the interfaces
in an internal header file. Move the trylock required during the panic
into the DRM core's sources.

[PATCH v3 13/14] drm/panic: Move panic display code into helper library

[Thomas Zimmermann]

Move drm_plane_helper_display_panic_screen() and the existing panic-
display code into drm_panic_helper.c. Rename symbols accordingly.
Also update the QR-related code and the bindings accordingly.

Link the rsp. object file into drm_kms_helper.ko. Eventually the code
will become a DRM drawing library, together with DRM's format and draw
helpers. This requires more preparation. until then, KMS helpers serve
as a module. All DRM drivers link it anyway.

Add a new section about drawing helpers to the documentation of the KMS
helpers. List format and panic helpers there.

v2:
- fix dependencies on other DRM modules (Randy, Sashiko)
- provide placeholders for drm_panic_helper_{init,exit}() (Sashiko)

[PATCH v3 14/14] drm/panic: Compile KUnit tests as module

[Thomas Zimmermann]

Fix dependency of the panic-helper KUnit tests on CONFIG_DRM_KUNIT_TEST=y
and make them build as a module. Export the necessary interfaces from the
panic helpers iff the KUnit framework has been enabled.

Select DRM_PANIC_HELPER from DRM_KUNIT_TEST to meet the dependencies of
the panic-helper tests.

It is now possible to run the tests by modprobe-ing drm_panic_helper_test
at runtime.

v3:
- clean up after each test case (Sashiko)
v2:
- fix parameter order in decl of drm_panic_helper_draw_screen_qr()
  (Sashiko)
