cover drm: Annotate structs with __counted_by

Hi,

This is a batch of patches touching drm for preparing for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

As found with Coccinelle[1], add __counted_by to structs that would benefit from the annotation.

Since the element count member must be set before accessing the annotated flexible array member, some patches also move the member's initialization earlier. (These are noted in the individual patches.)

Re: [PATCH 8/9] drm/vmwgfx: Annotate struct vmw_surface_dirty with __counted_by

In reply to Kees Cook
Quoted 33 lines · Kees Cook

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

As found with Coccinelle[1], add __counted_by for struct vmw_surface_dirty.

In reply to Kees Cook
Quoted 10 lines · Kees Cook

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

As found with Coccinelle[1], add __counted_by for struct smu10_voltage_dependency_table.

Mhm, I'm not sure if this is a good idea. That is a structure filled in by the firmware, isn't it?

That would imply that we might need to byte swap count before it is checkable.

Christian.

Mhm, I'm not sure if this is a good idea. That is a structure filled in by the firmware, isn't it?

That would imply that we might need to byte swap count before it is checkable.

True. Good point. Same for the other amdgpu patch.

The script found this instance because of this:

static int smu10_get_clock_voltage_dependency_table(struct pp_hwmgr *hwmgr,
struct smu10_voltage_dependency_table **pptable, uint32_t num_entry, const DpmClock_t *pclk_dependency_table)

        if (NULL == ptable)
                return -ENOMEM;

        ptable->count = num_entry;

So the implication is that it's native byte order... but you tell me! I certainly don't want this annotation if it's going to break stuff. :)

In this case, the code is for an integrated GPU in an x86 CPU so the firmware and driver endianness match. You wouldn't find a stand alone dGPU that uses this structure. In this case it's ok. False alarm.

This is a batch of patches touching drm for preparing for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

As found with Coccinelle[1], add __counted_by to structs that would benefit from the annotation.

Since this got Acks, I figure I should carry it in my tree. Let me know if this should go via drm instead.

Applied to for-next/hardening, thanks!

STOP! In a follow up discussion Alex and I figured out that this won't work.

I'm so confused; from the discussion I saw that Alex said both instances were false positives?

The value in the structure is byte swapped based on some firmware endianness which not necessary matches the CPU endianness.

SMU10 is APU only so the endianess of the SMU firmware and the CPU will always match.

Please revert that one from going upstream if it's already on it's way.

And because of those reasons I strongly think that patches like this should go through the DRM tree :)

Sure, that's fine -- please let me know. It was others Acked/etc. Who should carry these patches?

Probably best if the relevant maintainer pick them up individually.

Some of those structures are filled in by firmware/hardware and only the maintainers can judge if that value actually matches what the compiler needs.

We have cases where individual bits are used as flags or when the size is byte swapped etc...

Even Alex and I didn't immediately say how and where that field is actually used and had to dig that up. That's where the confusion came from.

Christian.

I wasn't 100% sure for the VC4 patch, but pushed the whole set to drm-misc-next anyway.

This also means that the patches are now auto merged into the drm-tip integration branch and should any build or unit test go boom we should notice immediately and can revert it pretty easily.

Thanks,
