[PATCH] drm/modes: Fix division by zero error

[Ziqi Zhao]

In the bug reported by Syzbot, the variable `den == (1 << 22)` and
`mode->vscan == (1 << 10)`, causing the multiplication to overflow and
accidentally make `den == 0`. To prevent any chance of overflow, we
replace `num` and `den` with 64-bit unsigned integers, and explicitly
check if the divisor `den` will overflow. If so, we employ full 64-bit
division with rounding; otherwise we keep the 64-bit to 32-bit division
that could potentially be better optimized.

In order to minimize the performance overhead, the overflow check for
`den` is wrapped with an `unlikely` condition. Please let me know if
this usage is appropriate.

I think making them u64 would be more clear.

More intuitively, den > UINT_MAX.

More intuitively, DIV64_U64_ROUND_CLOSEST(num, den).

The else after a branch with return is unnecessary. Someone's going to
send a patch to remove it later if you leave it in.

[Intel-gfx] [PATCH v2] drm/modes: Fix division by zero error

[Ziqi Zhao]

In the bug reported by Syzbot, the variable `den == (1 << 22)` and
`mode->vscan == (1 << 10)`, causing the multiplication to overflow and
accidentally make `den == 0`. To prevent any chance of overflow, we
replace `num` and `den` with 64-bit unsigned integers, and explicitly
check if the divisor `den` will overflow. If so, we employ full 64-bit
division with rounding; otherwise we keep the 64-bit to 32-bit division
that could potentially be better optimized.

In order to minimize the performance overhead, the overflow check for
`den` is wrapped with an `unlikely` condition. Please let me know if
this usage is appropriate.

Come to think of it, maybe the subject should mention "fix overflow"
instead, but no biggie.

[Intel-gfx] [PATCH v3] drm/modes: Fix division by zero due to overflow

[Ziqi Zhao]

In the bug reported by Syzbot, the variable `den == (1 << 22)` and
`mode->vscan == (1 << 10)`, causing the multiplication to overflow and
accidentally make `den == 0`. To prevent any chance of overflow, we
replace `num` and `den` with 64-bit unsigned integers, and explicitly
check if the divisor `den` will overflow. If so, we employ full 64-bit
division with rounding; otherwise we keep the 64-bit to 32-bit division
that could potentially be better optimized.

In order to minimize the performance overhead, the overflow check for
`den` is wrapped with an `unlikely` condition. Please let me know if
this usage is appropriate.
