If an input number x for int_sqrt() has the highest bit set, then
__ffs(x) is 64. (1UL << 64) is an overflow and breaks the algorithm.
Just subtracting 1 is an even better guess for the initial
value of m and that's what also used to be done in earlier
versions of this code.

This is confusing, because the patch doesn't go near an __ffs().

I think this one is fine, because __fls() gives you back 0-63 (or
undefined, but the previous <= 1 check handles that case).

This just looks like a copy-paste error because there isn't an __fls64().
But I think your suggestion here is ok, given the previous check against
ULONG_MAX.

Hmm. We probably *should* add a __fls64().
There looks to be only one user of int_sqrt64(), and that one is
confused. It does int_sqrt64() twice, but since the inner one will
reduce the range to 32 bits, the outer one is just silly.
That one user also had better not be overflowing into the high bit -
it uses "s64" as a type and does seem to use signed operatons, so high
bit set really means negative. sqrt() returning something odd for a
negative number wouldn't be all that odd in that context.
But yes, our current int_sqrt64() does seem buggy as-is, because it's
*supposed* to work on u64's, even if I don't think we really have any
users that care.
And as Will mentioned, the regular int_sqrt() looks perfectly fine,
and subtracting 1 from the __fls() return value would actually
_introduce_ a bug.

Hello all,
my comment said ffs(), but the code only uses fls() and that's what I meant.

Right. No real bug, just not 100% correct code.

I think no bug introduced as the code handling 0 and 1 is already done.
For __fls() and fls64() I am actually using the folloing code:
/*
* fls - find last (most-significant) bit set
* Note fls(0) = 0, fls(1) = 1, fls(0x80000000) = 32.
*/
static __always_inline unsigned int flsl(unsigned long x)
{
return x ? sizeof(x) * 8 - __builtin_clzl(x) : 0;
}
Please note the "_builtin_clzl()" instead of the "_builtin_clz()".
The real bug is that we compute 1 to 64 for bit 0 to bit 63, whereas
the algorithm
expects 0 to 63 for the value of m.

Florian, you seem to be in denial.
__fls() returns 0-63. Your patch is *wrong* for the __fls() use,
because when you subtract 1, you get -1 to 62, and the -1 now
introduces the very undefined behavior you claim your patch fixes.
So your patch fixes one real case (int_sqrt64(), that has one user
that doesn't care) but it *BREAKS* the other case that is actually
much more widely used (int_sqrt()).
See what Will and I are complainig about?

II have a usecase (mlx90632) where this calculation worked on arm64
(nexus), but not in normal 32-bit arm (beaglebone). I have tried going
with full u64 to u64, but I was persuaded that it is not necessary and
testing on black body (sensor range from 0 - 80 degrees) confirmed
that for my calculations u32/u64 is enough. Because of the testing
range (and keep in mind it is casted to signed after two sqrts) the
high bit might never affect my end result, but I needed precision, not
the range. Inside the function the b was 32bit on 32bit core, but I
needed it to be 64bit. To keep it similar to existing int_sqrt, I have
decided to just type all variables there to 64bit.
We have implementation of this with doubles (see datasheet) and I
ported it to integer on arm64. The end result was fairly similar
calculation (for within object tempearture range from 0-80), between
both.

I introduced strong types for existing int_sqrt implementation to keep
it aligned between 64bit and 32bit.

I have just re-read the patch submit discussion and a sqrt of 64bit
number can never be more than 32bit. That is why u32 return value is
enough. But I do not clearly remember if I tested with outside
int_sqrt (insted int_sqrt64). We still have everything, so I could
test if that is the suggestion.

Right. And that's exactly why I thought it was so odd how the
mlx90632.c driver - which is the only user of int_sqrt64() - does a
nested one.
It would be sufficient to do
int_sqrt(int_sqrt64(..))
because the domain on the outer one isn't actually 64 bits, it's only 32 bits.
But it's just a slight confusion and doesn't really matter much.
The bug in int_sqrt64() is real, but as mentioned, the calculations
done to generate the argument for that one user do seem to all be
*signed*. If it overflows into the high bit of an u64 (which is where
the off-by-one bug would matter), then the types in that one user are
already wrong.
So it would probably be a good idea to clarify the single user too while at it.

I've applied this part of the patch as commit fbfaf851902c ("fix
int_sqrt64() for very large numbers") with slightly edited commit
log.
I still think there are some oddities in here in the types. I
mentioned the caller that unnecessarily does the int_sqrt64() twice,
even though the outer one doesn't actually take a 64-bit value.
But in the very line above, there's another type oddity: the "& ~1ULL"
is entirely the wrong type. The shift *count* shouldn't be an unsigned
long long, so that type doesn't make much sense. It should be just a
~1, or even just "62".
But I didn't actually start micro-editing the patch, and just did that
one-liner off-by-one fix.

Thanks for the patch - I its indeed my copy-paste error, because
__fls64 does not exist on 32bit CPU, but the fls64 is not "equal"
replacement. I am very sorry for the bug.

True. This is oddity is originating from time where mlx90632 used its
own function for int_sqrt64 on 32bit.

This was also inline with above copy-paste and variable expansion to
force the 64bit everywhere. I will prepare a patch to clean this line
to ~1, question is why does the int_sqrt is having UL if this should
just be "62". I was thinking because we want to cast to the type
before we shift.
