Could be so.

I've been seeing this one for a while.  And from this report I can't
figure out what tool emitted it.  Clang?

If you're going to use randconfig then shouldn't you make the config
available?  Or maybe quote the KCONFIG_SEED - presumably there's a way
for others to regenerate.

Anyway, the warning seems wrong to me.


#define PAGE_SIZE               (_AC(1,UL) << PAGE_SHIFT)

#define BLOCKS_PER_PAGE  (PAGE_SIZE/512)

	inode->i_blocks += BLOCKS_PER_PAGE << folio_order(folio);

so the RHS here should have unsigned long type.  Being able to generate
the cpp output would be helpful.  That requires the .config.

This is i386, so an unsigned long is 32-bit, but i_blocks is a blkcnt_t
i.e. a u64, which makes the shift without a cast of the LHS fishy.

Ah, of course, thanks.  I remember 32 bits ;)

Bizarre this started showing up now.  The recent patch was:

-       info->alloced += compound_nr(page);
-       inode->i_blocks += BLOCKS_PER_PAGE << compound_order(page);
+       info->alloced += folio_nr_pages(folio);
+       inode->i_blocks += BLOCKS_PER_PAGE << folio_order(folio);

so it could tell that compound_order() was small, but folio_order()
might be large?

Silencing the warning is a good thing, but folio_order() can (at the
moment) be at most 9 on i386, so it isn't actually going to be
larger than 4096.

This is a Smatch warning.

I normally look over Smatch warnings before forwarding kbuild-bot emails
but this email is a grab bag of static checker warnings from different
tools.

This warning has a high rate of false positives so I'm going to disable
it by default.

The heuristic is that "inode->i_blocks" is a u64 but this .config must
be for a 32bit CPU.

I'm just going to turn off all these warnings until I can figure out a
better heuristic.

Please stop building h8300  after the asm-generic tree is merged, the

The old code also generates a warning on my test system.  Smatch thinks
both compound_order() and folio_order() are 0-255.  I guess because of
the "unsigned char compound_order;" in the struct page.

It'd be nice if we could annotate that as "contains a value between
1 and BITS_PER_LONG - PAGE_SHIFT".  Then be able to optionally enable
a checker that ensures that's true on loads/stores.  Maybe we need a
language that isn't C :-P  Ada can do this ... I don't think Rust can.

Machine Parsable Comments.  It's a matter of figuring out the best
format and writing the code.

In Smatch, I have table of hard coded return values in the format:
<function> <old return> <new hard coded return>
https://github.com/error27/smatch/blob/master/smatch_data/db/kernel.return_fixes
I don't have code to handle something like BITS_PER_LONG or PAGE_SHIFT.
To be honest, Smatch code always assumes that PAGE_SIZE is 4096 but I
should actually look it up...  It's not impossible to do.  The GFP_KERNEL
values changed enough so that I eventually made that look up the actual
defines.

I also have a table in the database where I could edit the values of
(struct page)->compound_order.

Hi Arnd,

Thanks for the advice, we have stopped building h8300 for new kernel.
