[PATCH v2 0/3] drivers: Improve memory management for large object allocations when i915/shmem is used with iommu

[Krzysztof Karas]

It was observed that allocating large objects via i915 driver
(igt-gpu-tools/tests/gem_exec_big/single) the folios and their
pages were not handled properly leading to buffer corruptions
during relocations.
Furthermore, using iommu driver in this context would leave
residual mappings in memory that could not be released, hogging
available RAM even after the process ended.

Krzysztof Karas (3):
  drm/i915/gem: split shared memory allocation table logic
  drm/i915/shmem: Count mapped pages in a folio
  drivers/iommu: Catch scatterlist length overflows

[PATCH v2 1/3] drm/i915/gem: split shared memory allocation table logic

[Krzysztof Karas]

shmem_sg_alloc_table is a complex and hard to read function.
Split its logic into smaller pieces to improve readability and
reduce indentation. Change the main "for" loop into "while" to
get rid of obscure iterator "i" and be more explicit in
traversing scatterlist.

[PATCH v2 2/3] drm/i915/shmem: Count mapped pages in a folio

[Krzysztof Karas]

With addition of commit 029ae067431a
("drm/i915: Fix potential overflow of shmem scatterlist length")
max_segment size was included in calculating the number of pages
for the scatterlist. This meant that segment sizes considerably
smaller than number of pages in a folio (see shmem_get_pages(),
rebuild_st label for context), were not enough to jump to the
next folio, which has never been a problem before folios have
been introduced. In result, sg_set_folio() was called multiple
times with nr_pages smaller than folio size, using multitude of
scatterlists, all pointing to the beginning pages of the folio
and never fully covering its range of pages.

Track how many pages have already been counted in a folio to
ensure it is fully covered before reading next folio.

[PATCH v2 3/3] drivers/iommu: Catch scatterlist length overflows

[Krzysztof Karas]

It is possible, when a very large mapping uses a single
scatterlist, that padding overflows scatterlist's length field.
This results in:
 1) silently wrapping the value
 2) smaller than desired mappings produced by iommu_map_sg
 3) leaving mapped bytes in memory (no iommu_unmap)

Address this issue by adding overflow detection for previous
scatterlist length field.

 * Address overflows instead of unmapping erroneously mapped
 memory (Robin).

Awesome, thanks for figuring it out! Looks like this must date all the

Nit: we don't really need an "else" after a goto, but it's hardly a big 
deal (however if you did want to respin, note also that the preferred 
title tag here is "iommu/dma: ..."). Either way,

Reviewed-by: Robin Murphy <robin.murphy@arm.com>

I'd imagine Joerg can take this as an IOMMU fix, but FWIW if you did 
want an ack to take it through drm-fixes to keep it with the i915 
patches, I wouldn't foresee any significant risk of conflicts.

Thanks,
Robin.

any chance we can split this cleanup into smaller pieces?

This MAX_READS here is very ugly! Just use 2 and explain it in a
comment. In the 'if' below you can check out of "if (... || i)"
and still explain it in a comment.

Hi Krzysztof,

Please move the refactoring after the fix. We don't want to
create a dependency between a fix and a code refactoring, as
that makes it harder for maintainers to backport the fix.

If we are on the topic of personal preferences, I'd prefer
moving this to a variable instead of leaving a magic number
buried in the code. The comment is unnecessary if you figure out
what this loop does and in the end "2" is just a number somebody
picked way back.

I mean, sure, but is there a reason for using "count" instead of
"left"?

Okay, thanks for pinpointing this commit, I'll add the tag in

I'll be making another version anyway, so I can remove the
"else" and change the title :)

Thanks!

would this r-b still hold after above minor changes, or would
you prefer to have one final look at the finished change and
then decide whether you give your r-b?

FWIW since I'm looking at the thread - indeed if it's just a retry loop 
and the actual index value isn't significant, then often a count-down 
loop can be the most self-explanatory, e.g.:

	int retries = 2;

	while (retries--) {
		...
	}

Or perhaps in this case:

	do {
		folio = shmem_read_folio();
		if (IS_ERR(folio))
			i915_gem_shrink();
	while (!IS_ERR(folio) && --retries);
	return folio;

Indeed if it's just those tweaks then feel free to keep it, that's

Well, it's taken 10 years to be caught by a test which seemingly expects 
the mapping of a single absurdly giant scatterlist to fail anyway, so 
combined with the great urgency to get rid of scatterlists, I hardly see 
it being a big deal... This will always have returned an error due to 
the "ret < iova_len" condition at the end, the fix just means we can now 
error out earlier without passing a mangled list to iommu_map_sg() and 
corrupting the pagetable in the process.

Certainly if a list was initially malformed with an individual segment 
longer than the segment boundary mask then it's not going to do any 
favours here, but I suspect this is likely just regular iova_granule 
rounding overflowing when the segment boundary is the maximum 4GB, since 
the largest representable segment length is 4GB - 1. Note the 
off-by-an-exact-multiple-of-4GB error in Krzysztof's logging from the v1 
thread:

[   79.915571] iommu_dma_map_sg: ret = 7138717696, iova_len = 20023619584

Quite simply this code was never written with the expectation of mapping 
4GB+ of _physically contiguous_ memory in one go. We could possibly try 
adding a bunch of special-case complexity to allow treating UINT_MAX as 
4GB through iommu_map_sg() if there was a real need to make something 
which never worked start working, but going back to my initial point, it 
really doesn't seem worth the bother.

Thanks,
Robin.

So instead of addressing this in iommu, we should focus on
guarding in sg logic to prevent the overflows? Or would you
rather have this as additional, separate fix placed in this
series?

Sure, but how many servers had 0.5TB of RAM in 2015? And how many of 
those were running the arm64 DMA mapping code? As I said, both this 
merging logic and the iommu_map_sg() interface itself were essentially 
written to support media buffers on Android phones which didn't even 
have 4GB of RAM in total. Yes, things have moved on by now, but 
correspondingly it has also been decided that the ~30-year-old 
scatterlist design also doesn't scale to modern use-cases anyway, and is 
being replaced, so limitations of a "legacy" API that don't have any 
meaningful impact to its existing users are hardly something to panic 
about. If DRM does want to be able to *reliably* map massive amounts of 
RAM then it can adopt the new IOMMU API, for this and all the other 
reasons that that new API was promised to be "better".

> So I wouldn't be quite so dismissive that this is not something a real
> user can hit.

I'm not being dismissive - clearly it can be hit. My point is that 
anyone who *does* hit it can only expect it to fail (as indeed this 
particular IGT test seems to), because it has never worked. You cannot 
encode a 4GB scatterlist segment, because it overflows UINT_MAX. And if 
you did try to bodge it and pass a UINT_MAX length segment to 
iommu_map_sg() then that will also fail because it's not aligned to an 
IOMMU page size. It's purely the matter of *how* exactly it fails which 
could do with fixing.

AFAICS, the overflow can only happen with a 4GB boundary mask, and for 
two conditions:

- rounding up the current segment, when s->length + s->offset > 4GB - 
iova_granule (but still <= 4GB otherwise it's bogus anyway)
- padding the previous segment in the case where the current segment 
would otherwise cross the next boundary, when prev->offset = 0 and 
prev->length + s->length >= 4GB

So yes, limiting any individual segment to <=2GB would end up avoiding 
both those conditions, but it would also impact plenty of cases that 
*do* currently work fine, e.g. 1GB+3GB+3GB. The limitation is really 
that you can't have two consecutive segments where the first starts 
exactly on a 4GB boundary and the sum of both their sizes >=4GB.

Technically sg_alloc_table_from_pages() carries no such assumption, only 
sg_alloc_table_from_pages_segment() (or __sg_alloc_table_from_pages()) 
with the correct dma_seg_boundary value for the given device. But even 
then in the worst case, they should still end up splitting segments at 
4GB-PAGE_SIZE due to the fundamental int limitation, and so only be at 
risk of putting two such segments back-to-back.

Again, it's not "malformed", it's just an edge case of certain 
otherwise-valid scatterlist layouts that are not supported in this one 
DMA API implementation. Nothing in the DMA API ever guarantees that any 
particular mapping must succeed. Furthermore I don't see that anyone's 
asking for this to actually be supported, just to fail cleanly and 
correctly without inadvertently corrupting state.

Thanks,
Robin.
