This is a follow-up to the plane and CRTC reset removal series, and
part of a larger effort to remove the reset hook from all KMS objects.
The connector reset hook is overloaded: it is called both at probe
time to create the initial software state and during suspend/resume to
reset hardware and software state. These two roles have different
requirements, and the reset hook is not fallible, making error
handling difficult for the initial state allocation path.
While reset has the semantics to reset both the software and hardware
state, the vast majority of implementations and all the helpers only
reset the software state, making them equivalent to
atomic_create_state in practice. The atomic_create_state hook makes
this explicit: it only allocates and initializes a pristine state
without any side effect, and returns the state pointer or an ERR_PTR
on failure.
This series converts all connector drivers tree-wide from the reset hook
to atomic_create_state, then removes the reset hook from struct
drm_connector_funcs entirely. The conversions were done using a
combination of Coccinelle semantic patches, mechanical one-line
replacements and manual adjustments.

The panel bridge attach hook calls the connector's reset function to
initialize the connector state when the device is already registered.
Now that connectors are being migrated from the reset hook to
atomic_create_state, prefer it over reset and fall back to the reset
hook if atomic_create_state is not implemented.

Cc: dri-devel, Maxime Ripard, Maíra Canal, Dave Stevenson,
Raspberry Pi Kernel Maintenance, Ruben Wauters
Recent commits renamed other reset helpers to use the state_init
suffix when they only initialize properties rather than allocate or
update the object state itself.
drm_atomic_helper_connector_tv_margins_reset() falls in the same
category: it initializes the TV margin properties from the kernel
command line without allocating any state. It also reads the
connector state through connector->state, coupling it to the reset
path.
Rename it to drm_atomic_helper_connector_tv_margins_state_init() and
pass the connector state explicitly as a parameter. This decouples
it from the reset hook and prepares for the conversion to
atomic_create_state where connector->state is not yet assigned.

Recent commits renamed other reset helpers to use the state_init
suffix when they only initialize properties rather than allocate or
update the object state itself.
drm_atomic_helper_connector_tv_reset() falls in the same category:
it initializes the analog TV properties from the kernel command line
defaults without allocating any state. It also reads the connector
state through connector->state, coupling it to the reset path.
Rename it to drm_atomic_helper_connector_tv_state_init() and pass
the connector state explicitly as a parameter. This decouples it
from the reset hook and prepares for the conversion to
atomic_create_state where connector->state is not yet assigned.

The dw-hdmi driver calls drm_atomic_helper_connector_reset() during
connector creation to allocate an initial connector state needed by
drm_connector_attach_max_bpc_property(). However, the driver only
needs to allocate a pristine state, which is exactly what
atomic_create_state provides.
Convert to drm_atomic_helper_connector_create_state() with proper
error handling.

The gud connector reset implementation creates a pristine state,
then initializes driver-specific TV properties, margins, and
brightness from the initial state. It does not perform any hardware
reset.
Since this is equivalent to what atomic_create_state expects, convert
the reset function to an atomic_create_state hook that returns the
initialized state.

The sun4i TV connector reset implementation creates a pristine state
and initializes the analog TV properties. It does not perform any
hardware reset.
Since this is equivalent to what atomic_create_state expects, convert
the reset function to an atomic_create_state hook that returns the
initialized state.

The amdgpu_dm connector reset implementation creates a custom state
subclass, but only initializes a pristine state without resetting any
hardware. This is equivalent to what atomic_create_state expects.
Convert to it.

The malidp writeback connector reset implementation creates a custom
state subclass, but only initializes a pristine state without resetting
any hardware. This is equivalent to what atomic_create_state expects.
Convert to it.

The i915 connector initialization uses
__drm_atomic_helper_connector_reset() to set up the initial state
during connector allocation. However, it only needs to initialize
the state, not reset it.
Switch to __drm_atomic_helper_connector_state_init() and assign
connector->state explicitly, matching what atomic_create_state
expects.

The vmwgfx connector reset implementation creates a custom state
subclass, but only initializes a pristine state without resetting any
hardware. This is equivalent to what atomic_create_state expects.
Convert to it.

drm/panel: Add atomic_create_state support
The panel bridge attach hook calls the connector's reset function to
initialize the connector state when the device is already registered.
Now that connectors are being migrated from the reset hook to
atomic_create_state, prefer it over reset and fall back to the reset
hook if atomic_create_state is not implemented.

[Severity: High]
Does this early return leak the initialized connector resources?
Earlier in panel_bridge_attach(), drm_connector_init() is called:
ret = drm_connector_init(bridge->dev, connector,
&panel_bridge_connector_funcs,
panel->connector_type);
This successfully initializes the connector, allocates its IDA and name string,
and adds it to the DRM device's global connector_list.
When atomic_create_state() fails and we return PTR_ERR(conn_state) early,
drm_connector_cleanup() is bypassed. Because the bridge attach failed, the
caller (drm_bridge_attach()) aborts the setup and will not call the bridge's
detach hook where drm_connector_cleanup() is typically invoked.
As a result, the connector remains in dev->mode_config.connector_list while
its enclosing struct drm_panel memory is tied to the panel driver's lifecycle.
If the panel driver unbinds and frees its memory, the DRM core might traverse
a freed list node during drm_mode_config_cleanup() or subsequent connector
iterations, potentially leading to a use-after-free crash. Additionally, the
IDA and name string allocated by drm_connector_init() are leaked.

[Severity: High]
Does this change introduce a resource leak and a use-after-free in the error
path of panel_bridge_attach()?
By providing the atomic_create_state callback, panel_bridge_attach() will
now take a different branch when creating the state:
drivers/gpu/drm/drm_panel.c:panel_bridge_attach() {
...
ret = drm_connector_init(bridge->dev, connector,
&panel_bridge_connector_funcs,
panel->connector_type);
...
if (connector->funcs->atomic_create_state) {
struct drm_connector_state *conn_state;
conn_state = connector->funcs->atomic_create_state(connector);
if (IS_ERR(conn_state))
return PTR_ERR(conn_state);
...
}
If drm_atomic_helper_connector_create_state() fails, the function returns
the error directly.
Since the connector was successfully initialized by drm_connector_init()
earlier in the function, returning without calling drm_connector_cleanup()
appears to leak the connector's resources.
Could this also lead to a use-after-free when the DRM core later iterates
over dev->mode_config.connector_list containing a dangling pointer to this
uncleaned connector?

[Severity: Medium]
Can this assignment introduce a regression by causing a crash in the deferred
KUnit cleanup path if memory allocation fails?
In dm_test_crtc_set_crc_source_dprx_no_connector(), if
drm_atomic_helper_connector_create_state() fails, it returns ERR_PTR(-ENOMEM).
Because it's directly assigned to wb_conn->state, the assertion
KUNIT_ASSERT_NOT_ERR_OR_NULL(test, wb_conn->state) will fail, aborting the
test.
This test abortion jumps to KUnit's deferred cleanup routines. The previously
registered cleanup action dm_test_crc_connector_cleanup() invokes
drm_connector_cleanup(wb_conn).
Since wb_conn->state contains ERR_PTR(-ENOMEM), which is not NULL,
drm_connector_cleanup() will consider it a valid pointer and pass it to
drm_atomic_helper_connector_destroy_state(). This will blindly dereference
the error pointer, leading to an invalid memory access.
Should the return value be validated in a local variable before being assigned
to wb_conn->state to ensure it remains NULL on failure?

[Severity: Low]
Will this missing hook introduce a regression by triggering a kernel warning
during test connector initialization?
The KUnit test allocates a DRM device with the DRIVER_ATOMIC feature flag.
When dm_test_alloc_real_connector() initializes the connector using
drmm_connector_init(), it calls into drm_connector_init_only().
Because dm_test_connector_funcs omits both the .atomic_destroy_state and
.atomic_duplicate_state hooks, this explicitly violates the core DRM check:
WARN_ON(drm_drv_uses_atomic_modeset(dev) &&
(!funcs->atomic_destroy_state || !funcs->atomic_duplicate_state))
This causes a warning to fire unconditionally during KUnit test execution.
Should we add the required hooks to satisfy the API contract for this
test connector?

drm/atomic-state-helper: Rename connector_tv_reset to state_init
This commit renames drm_atomic_helper_connector_tv_reset to
drm_atomic_helper_connector_tv_state_init. It adds a connector state
parameter to decouple the initialization from the reset hook, preparing it
for contexts like atomic_create_state where the connector state isn't
assigned yet.

[Severity: High]
Since the new state parameter is added to decouple this function from
the reset hook, should this call pass the newly provided state instead of
connector->state?
When a driver like vc4_vec calls this via its atomic_create_state hook,
connector->state is not yet assigned and is NULL.
Passing connector->state here forwards a NULL pointer to
drm_atomic_helper_connector_tv_margins_state_init(), which then writes
directly to state->tv.margins.left, leading to a NULL pointer dereference
during device probe:
void drm_atomic_helper_connector_tv_margins_state_init(struct drm_connector_state *state,
struct drm_connector *connector)
{
struct drm_cmdline_mode *cmdline = &connector->cmdline_mode;
state->tv.margins.left = cmdline->tv_margins.left;

[Severity: High]
Does this trigger a NULL pointer dereference during initialization?
When the DRM core resets the connector state, it explicitly clears the old
state before invoking the .atomic_create_state hook:
drm_mode_config_connector_reset_with_create_state() {
...
if (connector->state) {
...
connector->state = NULL;
}
return drm_mode_config_connector_create_state(connector);
}
The core helper drm_atomic_helper_connector_tv_state_init() then mistakenly
passes the unassigned connector->state down to the margins initialization
instead of the newly allocated state:
drm_atomic_helper_connector_tv_state_init() {
...
drm_atomic_helper_connector_tv_margins_state_init(connector->state,
connector);
}
This causes drm_atomic_helper_connector_tv_margins_state_init() to
unconditionally dereference the NULL state pointer:
drm_atomic_helper_connector_tv_margins_state_init(state, ...) {
...
state->tv.margins.left = cmdline->tv_margins.left;
...
}
The previous .reset hook implementation masked this core helper bug because
it assigned connector->state prior to calling the TV state initialization
helper.
Could we fix the core helper to pass the correct state pointer, or should
this driver handle the initialization differently to avoid the crash?

[Severity: High]
Will this cause a NULL pointer dereference during display initialization?
The core DRM function drm_mode_config_connector_reset_with_create_state()
explicitly sets connector->state to NULL before invoking the
atomic_create_state hook.
This means connector->state is NULL when
drm_atomic_helper_connector_tv_state_init() is called here.
Looking at drm_atomic_helper_connector_tv_state_init() in
drm_atomic_state_helper.c, it ignores the local state parameter when
initializing margins and instead passes connector->state:
void drm_atomic_helper_connector_tv_state_init(
struct drm_connector_state *state,
struct drm_connector *connector)
{
...
drm_atomic_helper_connector_tv_margins_state_init(connector->state,
connector);
}
Because connector->state is NULL in this context, does calling this
helper result in a guaranteed crash when the margins initializer
attempts to dereference the state parameter?

driver-specific defaults without resetting any hardware. This is
equivalent to what atomic_create_state expects. Convert to it.

[Severity: Medium]
Will dropping this call to nouveau_conn_attach_properties() cause MST
connectors to silently lose access to their DRM properties?
Before this patch, MST connectors would get properties like underscan_property,
scaling_mode_property, dithering_mode, and vibrant_hue registered here.
Without this call, userspace compositors might lose access to these standard
digital output properties.
[Severity: High]
If atomic_create_state() returns an error pointer, this assigns it directly
to mstc->connector.state.
> + if (IS_ERR(mstc->connector.state)) {

Could passing this error pointer to drm_connector_cleanup() result in a kernel
panic?
If we take this error path, drm_connector_cleanup() checks if connector->state
is set (which is true for ERR_PTR), and calls atomic_destroy_state().
This passes the error pointer down to nouveau_conn_atomic_destroy_state(),
which will dereference the invalid pointer and panic.

[Severity: High]
On older non-atomic hardware (pre-NV50), this returns a pointer to the
statically embedded nv_connector->properties_state.
The caller nouveau_connector_create() now unconditionally assigns this returned
pointer to connector->state. When the connector is later destroyed or reset,
drm_connector_cleanup() will invoke nouveau_conn_atomic_destroy_state(),
which unconditionally calls kfree() on the state pointer.
Can calling kfree() on this statically embedded struct pointer cause memory
corruption and a kernel panic?

[Severity: High]
Similar to the issue in nv50_mstc_new(), if atomic_create_state() fails,
the error pointer is assigned to connector->state.
The goto drm_conn_err path calls drm_connector_cleanup(), which will attempt to
clean up the state using the error pointer.
Does this lead to a panic during the error path cleanup?

to drm_atomic_helper_connector_create_state() and adds proper error handling.

[Severity: High]
Does this code handle failures from drm_connector_init_with_ddc() correctly?
Looking at dw_hdmi_connector_create(), drm_connector_init_with_ddc() is called
just before this block, but its return value is ignored:
drm_connector_init_with_ddc(hdmi->bridge.dev, connector,
&dw_hdmi_connector_funcs,
DRM_MODE_CONNECTOR_HDMIA,
hdmi->ddc);
If this initialization fails, connector->base.properties remains uninitialized
(NULL).
When execution continues to drm_connector_attach_max_bpc_property(), it will
attempt to attach the property and dereference connector->base.properties,
resulting in a NULL pointer dereference.
>
> drm_connector_attach_max_bpc_property(connector, 8, 16);
[Severity: Medium]
Will this max_bpc initialization be lost during a drm_mode_config_reset()?
The driver assigns .atomic_create_state =
drm_atomic_helper_connector_create_state in dw_hdmi_connector_funcs without
a custom hook to restore max_bpc.
If a host DRM driver calls drm_mode_config_reset(), the core fallback in
drm_mode_config_connector_reset_with_create_state() will destroy this
initially allocated state and replace it with a newly allocated one:
if (connector->state) {
connector->funcs->atomic_destroy_state(connector, connector->state);
connector->state = NULL;
}
return drm_mode_config_connector_create_state(connector);
This wipes out the max_bpc property attached here, resetting it to 0. This
could cause the driver to incorrectly fall back to 8-bit color depth later
in dw_hdmi_bridge_mode_set().

drm/amdgpu: dm: Convert to atomic_create_state
The amdgpu_dm connector reset implementation creates a custom state
subclass, but only initializes a pristine state without resetting any
hardware. This is equivalent to what atomic_create_state expects.
Convert to it.

[Severity: High]
If memory allocation fails during atomic_create_state() and we return early
here, does it skip mandatory connector initialization?
Since amdgpu_dm_connector_init_helper() returns void, the caller
amdgpu_dm_connector_init() is unaware of the failure and continues execution.
It subsequently calls amdgpu_dm_initialize_dp_connector(), which
unconditionally dereferences aconnector->dc_link->ddc.
Since aconnector->dc_link assignment is skipped in the aborted helper, could
this result in a NULL pointer dereference?

[Severity: High]
Can this overwrite the connector->state pointer and leak the previously
allocated state?
Earlier in dm_dp_add_mst_connector(), amdgpu_dm_connector_init_helper() is
called, which allocates and initializes a new connector state and assigns it
to connector->state. Overwriting it here appears to drop custom properties
attached to the state in the interim (such as max_requested_bpc set by
drm_connector_attach_max_bpc_property).
Additionally, amdgpu_dm_connector_atomic_create_state() can return
ERR_PTR(-ENOMEM) on allocation failure. Because this is directly assigned to
connector->state without an IS_ERR() check, will the DRM core subsequently
dereference this error pointer?
