42a7efc865 iommu: iommu-debug: don't pass null character to copy_to_user
Doing a cat on pte,test_virt_addr from adb shell prints a null
character as well which is at the end of the string this is not
required so, don't pass this null character to copy_to_user.

412b07f4da iommu: dma-mapping-fast: Add a check for count in fast_smmu_alloc
In fast_smmu_alloc size_t variable size is type casted to int
variable count, this variable count can get truncated and can
result in memory corruption during unmap, make count as size_t
and also add a check for count as sg_alloc_table_from_pages
accepts unsigned int value for count.

6a8e47eb57 iommu/iommu-debug: fix buffer overflows in debugfs read functions
The kernel buffer 'ubuf' can overflow while copying data to user
space in debugfs read functions. Fix it by limiting the length of
data to be copied to userspace.

ace0b79c2f iommu/arm-smmu: Add Hibernation support
This adds support for saving the arm-smmu client's context
just before going into hibernation. This context is restored
on the subesequent hibernate restore.
Also, invalidate the TLB during the restore phase to avoid
wrong translations post-resume.

ba826181ed iommu/debug: Add mutex to make attach/detach thread safe
This mutex lock will help to synchronise the usage of iommu domain
structure which is getting used by multiple threads to perform
iommu attach and iommu detach in case of any error.

Without this change we are seeing page poisoning - write after free
when running stress tests using iommu-debug test cases.

082efbb048 x86/cpufeature: Remove unused and seldomly used cpu_has_xx macros
commit 362f924b64ba0f4be2ee0cb697690c33d40be721 upstream.

Those are stupid and code should use static_cpu_has_safe() or
boot_cpu_has() instead. Kill the least used and unused ones.

The remaining ones need more careful inspection before a conversion can
happen. On the TODO.

a7e67521c4 iommu/vt-d: Fix a potential memory leak
commit bbe4b3af9d9e3172fb9aa1f8dcdfaedcb381fc64 upstream.

A memory block was allocated in intel_svm_bind_mm() but never freed
in a failure path. This patch fixes this by free it to avoid memory
leakage.

fb4ff6c732 iommu/vt-d: clean up pr_irq if request_threaded_irq fails
[ Upstream commit 72d548113881dd32bf7f0b221d031e6586468437 ]

It is unlikely request_threaded_irq will fail, but if it does for some
reason we should clear iommu->pr_irq in the error path. Also
intel_svm_finish_prq shouldn't try to clean up the page request
interrupt if pr_irq is 0. Without these, if request_threaded_irq were
to fail the following occurs:

fail with no fixes:

5fbe79a375 iommu/omap: Register driver before setting IOMMU ops
[ Upstream commit abaa7e5b054aae567861628b74dbc7fbf8ed79e8 ]

Move the registration of the OMAP IOMMU platform driver before
setting the IOMMU callbacks on the platform bus. This causes
the IOMMU devices to be probed first before the .add_device()
callback is invoked for all registered devices, and allows
the iommu_group support to be added to the OMAP IOMMU driver.

While at this, also check for the return status from bus_set_iommu.

2ebf08beed iommu/iova: Fix underflow bug in __alloc_and_insert_iova_range
[ Upstream commit 5016bdb796b3726eec043ca0ce3be981f712c756 ]

Normally, calling alloc_iova() using an iova_domain with insufficient
pfns remaining between start_pfn and dma_limit will fail and return a
NULL pointer. Unexpectedly, if such a "full" iova_domain contains an
iova with pfn_lo == 0, the alloc_iova() call will instead succeed and
return an iova containing invalid pfns.

This is caused by an underflow bug in __alloc_and_insert_iova_range()
that occurs after walking the "full" iova tree when the search ends
at the iova with pfn_lo == 0 and limit_pfn is then adjusted to be just
below that (-1). This (now huge) limit_pfn gives the impression that a
vast amount of space is available between it and start_pfn and thus
a new iova is allocated with the invalid pfn_hi value, 0xFFF.... .

To rememdy this, a check is introduced to ensure that adjustments to
limit_pfn will not underflow.

This issue has been observed in the wild, and is easily reproduced with
the following sample code.

	struct iova_domain *iovad = kzalloc(sizeof(*iovad), GFP_KERNEL);
	struct iova *rsvd_iova, *good_iova, *bad_iova;
	unsigned long limit_pfn = 3;
	unsigned long start_pfn = 1;
	unsigned long va_size = 2;

	init_iova_domain(iovad, SZ_4K, start_pfn, limit_pfn);
	rsvd_iova = reserve_iova(iovad, 0, 0);
	good_iova = alloc_iova(iovad, va_size, limit_pfn, true);
	bad_iova = alloc_iova(iovad, va_size, limit_pfn, true);

Prior to the patch, this yielded:
	*rsvd_iova == {0, 0}   /* Expected */
	*good_iova == {2, 3}   /* Expected */
	*bad_iova  == {-2, -1} /* Oh no... */

After the patch, bad_iova is NULL as expected since inadequate
space remains between limit_pfn and start_pfn after allocating
good_iova.

f511ba8a50 iommu/arm-smmu-v3: Don't free page table ops twice
commit 57d72e159b60456c8bb281736c02ddd3164037aa upstream.

Kasan reports a double free when finalise_stage_fn fails: the io_pgtable
ops are freed by arm_smmu_domain_finalise and then again by
arm_smmu_domain_free. Prevent this by leaving pgtbl_ops empty on failure.

dc41b6e35f iommu/vt-d: Fix scatterlist offset handling
commit 29a90b70893817e2f2bb3cea40a29f5308e21b21 upstream.

The intel-iommu DMA ops fail to correctly handle scatterlists where
sg->offset is greater than PAGE_SIZE - the IOVA allocation is computed
appropriately based on the page-aligned portion of the offset, but the
mapping is set up relative to sg->page, which means it fails to actually
cover the whole buffer (and in the worst case doesn't cover it at all):

    (sg->dma_address + sg->dma_len) ----+
    sg->dma_address ---------+          |
    iov_pfn------+           |          |
                 |           |          |
                 v           v          v
iova:   a        b        c        d        e        f
        |--------|--------|--------|--------|--------|
                          <...calculated....>
                 [_____mapped______]
pfn:    0        1        2        3        4        5
        |--------|--------|--------|--------|--------|
                 ^           ^          ^
                 |           |          |
    sg->page ----+           |          |
    sg->offset --------------+          |
    (sg->offset + sg->length) ----------+

As a result, the caller ends up overrunning the mapping into whatever
lies beyond, which usually goes badly:

[  429.645492] DMAR: DRHD: handling fault status reg 2
[  429.650847] DMAR: [DMA Write] Request device [02:00.4] fault addr f2682000 ...

Whilst this is a fairly rare occurrence, it can happen from the result
of intermediate scatterlist processing such as scatterwalk_ffwd() in the
crypto layer. Whilst that particular site could be fixed up, it still
seems worthwhile to bring intel-iommu in line with other DMA API
implementations in handling this robustly.

To that end, fix the intel_map_sg() path to line up the mapping
correctly (in units of MM pages rather than VT-d pages to match the
aligned_nrpages() calculation) regardless of the offset, and use
sg_phys() consistently for clarity.

commit ce76353f169a6471542d999baf3d29b121dce9c0 upstream.

The function only sends the flush command to the IOMMU(s),
but does not wait for its completion when it returns. Fix
that.

34701923eb iommu: fix smmu_secure_pool access list after free issue
secure_pool_list is initialized during domain alloc and freed with domain
free.
commit e6a18bb617 ("iommu: free io pgtable during domain detach.") frees
the secure_pool_list as part of iommu detach sequence, and uses the same
list head as part of iommu attach.  This uncovers an existing bug where
list was not being deleted from secure_pool_list and associated memory was
being freed.  This resulted in invalid secure_pool_list head pointing to a
location already freed and resulted in kernel BUG of access after free
during iommu attach.

e6a18bb617 iommu: free io pgtable during domain detach.
Pagetable pgd is allocated in arm_smmu_init_domain_context and is freed in
arm_smmu_domain_free. Client can attach/detach domain without freeing the
same. This causes memory leak. This was introduced with
commit fe676929a9 ("iommu/arm-smmu: fix a DOMAIN_ATTR_DYNAMIC memory
leak")

Free io pgtables in arm_smmu_destroy_domain_context, which is invoked at
the time of domain detach.

commit 73dbd4a4230216b6a5540a362edceae0c9b4876b upstream.

In function amd_iommu_bind_pasid(), the control flow jumps
to label out_free when pasid_state->mm and mm is NULL. And
mmput(mm) is called.  In function mmput(mm), mm is
referenced without validation. This will result in a NULL
dereference bug. This patch fixes the bug.

48952c6d51 iommu: Handle default domain attach failure
commit 797a8b4d768c58caac58ee3e8cb36a164d1b7751 upstream.

We wouldn't normally expect ops->attach_dev() to fail, but on IOMMUs
with limited hardware resources, or generally misconfigured systems,
it is certainly possible. We report failure correctly from the external
iommu_attach_device() interface, but do not do so in iommu_group_add()
when attaching to the default domain. The result of failure there is
that the device, group and domain all get left in a broken,
part-configured state which leads to weird errors and misbehaviour down
the line when IOMMU API calls sort-of-but-don't-quite work.

Check the return value of __iommu_attach_device() on the default domain,
and refactor the error handling paths to cope with its failure and clean
up correctly in such cases.

3de9630abe iommu/vt-d: Don't over-free page table directories
commit f7116e115acdd74bc75a4daf6492b11d43505125 upstream.

dma_pte_free_level() recurses down the IOMMU page tables and frees
directory pages that are entirely contained in the given PFN range.
Unfortunately, it incorrectly calculates the starting address covered
by the PTE under consideration, which can lead to it clearing an entry
that is still in use.

This occurs if we have a scatterlist with an entry that has a length
greater than 1026 MB and is aligned to 2 MB for both the IOMMU and
physical addresses. For example, if __domain_mapping() is asked to map a
two-entry scatterlist with 2 MB and 1028 MB segments to PFN 0xffff80000,
it will ask if dma_pte_free_pagetable() is asked to PFNs from
0xffff80200 to 0xffffc05ff, it will also incorrectly clear the PFNs from
0xffff80000 to 0xffff801ff because of this issue. The current code will
set level_pfn to 0xffff80200, and 0xffff80200-0xffffc01ff fits inside
the range being cleared. Properly setting the level_pfn for the current
level under consideration catches that this PTE is outside of the range
being cleared.

This patch also changes the value passed into dma_pte_free_level() when
it recurses. This only affects the first PTE of the range being cleared,
and is handled by the existing code that ensures we start our cursor no
lower than start_pfn.

This was found when using dma_map_sg() to map large chunks of contiguous
memory, which immediatedly led to faults on the first access of the
erroneously-deleted mappings.

eb7038b13a iommu/dma: Remove bogus dma_supported() implementation
Back when this was first written, dma_supported() was somewhat of a
murky mess, with subtly different interpretations being relied upon in
various places. The "does device X support DMA to address range Y?"
uses assuming Y to be physical addresses, which motivated the current
iommu_dma_supported() implementation and are alluded to in the comment
therein, have since been cleaned up, leaving only the far less ambiguous
"can device X drive address bits Y" usage internal to DMA API mask
setting. As such, there is no reason to keep a slightly misleading
callback which does nothing but duplicate the current default behaviour;
we already constrain IOVA allocations to the iommu_domain aperture where
necessary, so let's leave DMA mask business to architecture-specific
code where it belongs.

b39c609072 iommu/arm-smmu: Correctly calculate and use the TTBR1 pagetable
Due to an egregious misunderstanding of the specification it
was thought that to do the TTBR1 matching correctly the sign
extension bit needed to match the input address space. This
is incorrect - the TTBR1 range is determined by the size of
the TTBR1 space (in our case, the same as the input address
space). For example if the input address size is 36, the
effective range of the pagetables are:

TTBR0: 0x00000000_00000000 - 0x0000000f_ffffffff
TTBR1: 0xfffffff0_00000000 - 0xffffffff_ffffffff

For its part the sign extension bit needs should be set based on
the upstream bus size. If the device has a UBS of 49 then the
sign extension bit is assumed by design to be 48 otherwise
the driver needs to pick the highest available bit and reduce
the input address space by 1.

Because the client driver shouldn't need to know the upstream
bus size, convention is to use a fully sign extended unsigned
long address for TTBR1 mappings. If the sign extension bit is set
lower than the upstream bus size some implementations assume that
bits above the sign extension bit need to be zero and breaks the
convention. Setting the sign extension bit correctly for the
upstream bus size ensures that sign extension always works.

The hardware will match an address to the TTBR1 if all the bits
between the sign extension bit and the input address size are set
to 1. We emulate this behavior in software when looking up a pagetable
for a software operation.

98d5e84363 iommu/vt-d: Flush the IOTLB to get rid of the initial kdump mappings
commit f73a7eee900e95404b61408a23a1df5c5811704c upstream.

Ever since commit 091d42e43d ("iommu/vt-d: Copy translation tables from
old kernel") the kdump kernel copies the IOMMU context tables from the
previous kernel. Each device mappings will be destroyed once the driver
for the respective device takes over.

This unfortunately breaks the workflow of mapping and unmapping a new
context to the IOMMU. The mapping function assumes that either:

1) Unmapping did the proper IOMMU flushing and it only ever flush if the
   IOMMU unit supports caching invalid entries.
2) The system just booted and the initialization code took care of
   flushing all IOMMU caches.

This assumption is not true for the kdump kernel since the context
tables have been copied from the previous kernel and translations could
have been cached ever since. So make sure to flush the IOTLB as well
when we destroy these old copied mappings.
