[Intel-gfx] [PATCH v15 0/6] Fixes integer overflow or integer truncation issues in page lookups, ttm place configuration and scatterlist creation

[Gwan-gyeong Mun]

This patch series fixes integer overflow or integer truncation issues in
page lookups, ttm place configuration and scatterlist creation, etc.
We need to check that we avoid integer overflows when looking up a page,
and so fix all the instances where we have mistakenly used a plain integer
instead of a more suitable long.
And there is an impedance mismatch between the scatterlist API using
unsigned int and our memory/page accounting in unsigned long. That is we
may try to create a scatterlist for a large object that overflows returning
a small table into which we try to fit very many pages. As the object size
is under the control of userspace, we have to be prudent and catch the
conversion errors. To catch the implicit truncation as we switch from
unsigned long into the scatterlist's unsigned int, we use improved
overflows_type check and report E2BIG prior to the operation. This is
already used in our create ioctls to indicate if the uABI request is simply
too large for the backing store. 
And ttm place also has the same problem with scatterlist creation,
and we fix the integer truncation problem with the way approached by
scatterlist creation.
And It corrects the error code to return -E2BIG when creating gem objects
using ttm or shmem, if the size is too large in each case.

Linux 6.2 rc1 merged into drm-tip. I resend the same patch series as the
previous version, except for one patch[1] included in Linux 6.2 rc1 from
the previous v15 patch series.

There is no difference in the code from the previous version [2] that was
updated to v15 version. And it has already been confirmed by the CI results
of v15 that there is no regression caused by this patch series.

[Intel-gfx] [PATCH v15 1/6] drm/i915/gem: Typecheck page lookups

[Gwan-gyeong Mun]

From: Chris Wilson <chris@chris-wilson.co.uk>

We need to check that we avoid integer overflows when looking up a page,
and so fix all the instances where we have mistakenly used a plain
integer instead of a more suitable long. Be pedantic and add integer
typechecking to the lookup so that we can be sure that we are safe.
And it also uses pgoff_t as our page lookups must remain compatible with
the page cache, pgoff_t is currently exactly unsigned long.

v2: Move added i915_utils's macro into drm_util header (Jani N)
v3: Make not use the same macro name on a function. (Mauro)
    For kernel-doc, macros and functions are handled in the same namespace,
    the same macro name on a function prevents ever adding documentation
    for it.
v4: Add kernel-doc markups to the kAPI functions and macros (Mauoro)
v5: Fix an alignment to match open parenthesis
v6: Rebase
v10: Use assert_typable instead of exactly_pgoff_t() macro. (Kees)
v11: Change the use of assert_typable to assert_same_typable (G.G)
v12: Change to use static_assert(__castable_to_type(n ,T)) style since
     the assert_same_typable() macro has been dropped. (G.G)
v13: Change the use of __castable_to_type() to castable_to_type()
     Remove an unnecessary header include line. (G.G)

[Intel-gfx] [PATCH v15 2/6] drm/i915: Check for integer truncation on scatterlist creation

[Gwan-gyeong Mun]

From: Chris Wilson <chris@chris-wilson.co.uk>

There is an impedance mismatch between the scatterlist API using unsigned
int and our memory/page accounting in unsigned long. That is we may try
to create a scatterlist for a large object that overflows returning a
small table into which we try to fit very many pages. As the object size
is under the control of userspace, we have to be prudent and catch the
conversion errors.

To catch the implicit truncation we check before calling scattterlist
creation Apis. we use overflows_type check and report E2BIG if the
overflows may raise. When caller does not return errno, use WARN_ON to
report a problem.

This is already used in our create ioctls to indicate if the uABI request
is simply too large for the backing store. Failing that type check,
we have a second check at sg_alloc_table time to make sure the values
we are passing into the scatterlist API are not truncated.

v2: Move added i915_utils's macro into drm_util header (Jani N)
v5: Fix macros to be enclosed in parentheses for complex values
    Fix too long line warning
v8: Replace safe_conversion() with check_assign() (Kees)
v14: Remove shadowing macros of scatterlist creation api and fix to
     explicitly overflow check where the scatterlist creation APIs are
     called. (Jani)
v15: Add missing returning of error code when the WARN_ON() has been
     detected. (Jani)

[Intel-gfx] [PATCH v15 3/6] drm/i915: Check for integer truncation on the configuration of ttm place

[Gwan-gyeong Mun]

There is an impedance mismatch between the first/last valid page
frame number of ttm place in unsigned and our memory/page accounting in
unsigned long.
As the object size is under the control of userspace, we have to be prudent
and catch the conversion errors.
To catch the implicit truncation as we switch from unsigned long to
unsigned, we use overflows_type check and report E2BIG or overflow_type
prior to the operation.

v3: Not to change execution inside a macro. (Mauro)
    Add safe_conversion_gem_bug_on() macro and remove temporal
    SAFE_CONVERSION() macro.
v4: Fix unhandled GEM_BUG_ON() macro call from safe_conversion_gem_bug_on()
v6: Fix to follow general use case for GEM_BUG_ON(). (Jani)
v7: Fix to use WARN_ON() macro where GEM_BUG_ON() macro was used. (Jani)
v8: Replace safe_conversion() with check_assign() (Kees)
v14: Split one macro of assignment with checking of overflow to two steps,
     first overflow check, and second assignment.

[Intel-gfx] [PATCH v15 4/6] drm/i915: Check if the size is too big while creating shmem file

[Gwan-gyeong Mun]

The __shmem_file_setup() function returns -EINVAL if size is greater than
MAX_LFS_FILESIZE. To handle the same error as other code that returns
-E2BIG when the size is too large, it add a code that returns -E2BIG when
the size is larger than the size that can be handled.

v4: If BITS_PER_LONG is 32, size > MAX_LFS_FILESIZE is always false, so it
    checks only when BITS_PER_LONG is 64.

[Intel-gfx] [PATCH v15 6/6] drm/i915: Remove truncation warning for large objects

[Gwan-gyeong Mun]

From: Chris Wilson <chris@chris-wilson.co.uk>

Having addressed the issues surrounding incorrect types for local
variables and potential integer truncation in using the scatterlist API,
we have closed all the loop holes we had previously identified with
dangerously large object creation. As such, we can eliminate the warning
put in place to remind us to complete the review.

v6.2-rc1 is on drm-tip through drm-intel-fixes and topic/core-for-CI.
But if this series depends on a patch in the v6.2-rc1 we need to wait
drm-next to backmerge it, then we backmerge drm-next into drm-intel-next
and drm-intel-gt-next. Only then we can merge this series.
