b7a479c764 affs: initialize fsdata in affs_truncate()
[ Upstream commit eef034ac6690118c88f357b00e2b3239c9d8575d ]

When aops->write_begin() does not initialize fsdata, KMSAN may report
an error passing the latter to aops->write_end().

Fix this by unconditionally initializing fsdata.

623d111689 IB/hfi1: Remove user expected buffer invalidate race
[ Upstream commit b3deec25847bda34e34d5d7be02f633caf000bd8 ]

During setup, there is a possible race between a page invalidate
and hardware programming.  Add a covering invalidate over the user
target range during setup.  If anything within that range is
invalidated during setup, fail the setup.  Once set up, each
TID will have its own invalidate callback and invalidate.

85caef2cfd IB/hfi1: Fix expected receive setup error exit issues
[ Upstream commit e0c4a422f5246abefbf7c178ef99a1f2dc3c5f62 ]

Fix three error exit issues in expected receive setup.
Re-arrange error exits to increase readability.

Issues and fixes:
1. Possible missed page unpin if tidlist copyout fails and
   not all pinned pages where made part of a TID.
   Fix: Unpin the unused pages.

2. Return success with unset return values tidcnt and length
   when no pages were pinned.
   Fix: Return -ENOSPC if no pages were pinned.

3. Return success with unset return values tidcnt and length when
   no rcvarray entries available.

362c948972 RDMA/core: Fix ib block iterator counter overflow
[ Upstream commit 0afec5e9cea732cb47014655685a2a47fb180c31 ]

When registering a new DMA MR after selecting the best aligned page size
for it, we iterate over the given sglist to split each entry to smaller,
aligned to the selected page size, DMA blocks.

In given circumstances where the sg entry and page size fit certain
sizes and the sg entry is not aligned to the selected page size, the
total size of the aligned pages we need to cover the sg entry is >= 4GB.
Under this circumstances, while iterating page aligned blocks, the
counter responsible for counting how much we advanced from the start of
the sg entry is overflowed because its type is u32 and we pass 4GB in
size. This can lead to an infinite loop inside the iterator function
because the overflow prevents the counter to be larger
than the size of the sg entry.

Fix the presented problem by changing the advancement condition to
eliminate overflow.

eda11ab556 memory: tegra: Remove clients SID override programming
[ Upstream commit ef86b2c2807f41c045e5534d8513a8b83f63bc39 ]

On newer Tegra releases, early boot SID override programming and SID
override programming during resume is handled by bootloader.
In the function tegra186_mc_program_sid() which is getting removed, SID
override register of all clients is written without checking if secure
firmware has allowed write on it or not. If write is disabled by secure
firmware then it can lead to errors coming from secure firmware and hang
in kernel boot.
Also, SID override is programmed on-demand during probe_finalize() call
of IOMMU which is done in tegra186_mc_client_sid_override() in this same
file. This function does it correctly by checking if write is permitted
on SID override register. It also checks if SID override register is
already written with correct value and skips re-writing it in that case.

io_arm_poll_handler() it will find the old apoll entry and NULL

e944f1e37b io_uring: Clean up a false-positive warning from GCC 9.3.0
commit 0d7c1153d9291197c1dc473cfaade77acb874b4b upstream.

In io_recv(), if import_single_range() fails, the @flags variable is
uninitialized, then it will goto out_free.

After the goto, the compiler doesn't know that (ret < min_ret) is
always true, so it thinks the "if ((flags & MSG_WAITALL) ..."  path
could be taken.

The complaint comes from gcc-9 (Debian 9.3.0-22) 9.3.0:
```
  fs/io_uring.c:5238 io_recvfrom() error: uninitialized symbol 'flags'
```
Fix this by bypassing the @ret and @flags check when
import_single_range() fails.

Reasons:
 1. import_single_range() only returns -EFAULT when it fails.
 2. At that point, @flags is uninitialized and shouldn't be read.

940e8922c1 mm/khugepaged: fix collapse_pte_mapped_thp() to allow anon_vma
commit ab0c3f1251b4670978fde0bd54161795a139b060 upstream.

uprobe_write_opcode() uses collapse_pte_mapped_thp() to restore huge pmd,
when removing a breakpoint from hugepage text: vma->anon_vma is always set
in that case, so undo the prohibition.  And MADV_COLLAPSE ought to be able
to collapse some page tables in a vma which happens to have anon_vma set
from CoWing elsewhere.

Is anon_vma lock required?  Almost not: if any page other than expected
subpage of the non-anon huge page is found in the page table, collapse is
aborted without making any change.  However, it is possible that an anon
page was CoWed from this extent in another mm or vma, in which case a
concurrent lookup might look here: so keep it away while clearing pmd (but
perhaps we shall go back to using pmd_lock() there in future).

Note that collapse_pte_mapped_thp() is exceptional in freeing a page table
without having cleared its ptes: I'm uneasy about that, and had thought
pte_clear()ing appropriate; but exclusive i_mmap lock does fix the
problem, and we would have to move the mmu_notification if clearing those
ptes.

What this fixes is not a dangerous instability.  But I suggest Cc stable
because uprobes "healing" has regressed in that way, so this should follow
8d3c106e19e8 into those stable releases where it was backported (and may
want adjustment there - I'll supply backports as needed).

1aab00aa41 net/ulp: use consistent error code when blocking ULP
commit 8ccc99362b60c6f27bb46f36fdaaccf4ef0303de upstream.

The referenced commit changed the error code returned by the kernel
when preventing a non-established socket from attaching the ktls
ULP. Before to such a commit, the user-space got ENOTCONN instead
of EINVAL.

The existing self-tests depend on such error code, and the change
caused a failure:

  RUN           global.non_established ...
 tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107)
 non_established: Test failed at step #3
          FAIL  global.non_established

In the unlikely event existing applications do the same, address
the issue by restoring the prior error code in the above scenario.

Note that the only other ULP performing similar checks at init
time - smc_ulp_ops - also fails with ENOTCONN when trying to attach
the ULP to a non-established socket.

2e4c95a404 io_uring/net: fix fast_iov assignment in io_setup_async_msg()
commit 3e4cb6ebbb2bad201c1186bc0b7e8cf41dd7f7e6 upstream.

I hit a very bad problem during my tests of SENDMSG_ZC.
BUG(); in first_iovec_segment() triggered very easily.
The problem was io_setup_async_msg() in the partial retry case,
which seems to happen more often with _ZC.

iov_iter_iovec_advance() may change i->iov in order to have i->iov_offset
being only relative to the first element.

Which means kmsg->msg.msg_iter.iov is no longer the
same as kmsg->fast_iov.

But this would rewind the copy to be the start of
async_msg->fast_iov, which means the internal
state of sync_msg->msg.msg_iter is inconsitent.

I tested with 5 vectors with length like this 4, 0, 64, 20, 8388608
and got a short writes with:
- ret=2675244 min_ret=8388692 => remaining 5713448 sr->done_io=2675244
- ret=-EAGAIN => io_uring_poll_arm
- ret=4911225 min_ret=5713448 => remaining 802223  sr->done_io=7586469
- ret=-EAGAIN => io_uring_poll_arm
- ret=802223  min_ret=802223  => res=8388692

While this was easily triggered with SENDMSG_ZC (queued for 6.1),
it was a potential problem starting with 7ba89d2af17aa879dda30f5d5d3f152e587fc551
in 5.18 for IORING_OP_RECVMSG.
And also with 4c3c09439c08b03d9503df0ca4c7619c5842892e in 5.19
for IORING_OP_SENDMSG.

However 257e84a5377fbbc336ff563833a8712619acce56 introduced the critical
code into io_setup_async_msg() in 5.11.

311b298a33 io_uring: io_kiocb_update_pos() should not touch file for non -1 offset
commit 6f83ab22adcb77a5824d2c274dace0d99e21319f upstream.

-1 tells use to use the current position, but we check if the file is
a stream regardless of that. Fix up io_kiocb_update_pos() to only
dip into file if we need to. This is both more efficient and also drops
12 bytes of text on aarch64 and 64 bytes on x86-64.

487a086595 tracing: Use alignof__(struct {type b;}) instead of offsetof()
commit 09794a5a6c348f629b35fc1687071a1622ef4265 upstream.

Simplify:

  #define ALIGN_STRUCTFIELD(type) ((int)(offsetof(struct {char a; type b;}, b)))

with

  #define  ALIGN_STRUCTFIELD(type) __alignof__(struct {type b;})

Which works just the same.

430443f856 x86/fpu: Use _Alignof to avoid undefined behavior in TYPE_ALIGN
commit 55228db2697c09abddcb9487c3d9fa5854a932cd upstream.

WG14 N2350 specifies that it is an undefined behavior to have type
definitions within offsetof", see

  https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2350.htm

This specification is also part of C23.

Therefore, replace the TYPE_ALIGN macro with the _Alignof builtin to
avoid undefined behavior. (_Alignof itself is C11 and the kernel is
built with -gnu11).

ISO C11 _Alignof is subtly different from the GNU C extension
__alignof__. Latter is the preferred alignment and _Alignof the
minimal alignment. For long long on x86 these are 8 and 4
respectively.

The macro TYPE_ALIGN's behavior matches _Alignof rather than
__alignof__.

This reverts commit 78623b10fc9f8231802536538c85527dc54640a0 which is
commit 81d0bcf9900932633d270d5bc4a54ff599c6ebdb upstream.

This commit causes hiberation regressions on some platforms on kernels
older than 6.1.x (6.1.x and newer kernels works fine) so let's revert it
from 5.15 and older stable kernels.  This should be reverted from 6.0.x
as well, but that kernel is no longer supported.

de2af657ca arm64: efi: Execute runtime services from a dedicated stack
commit ff7a167961d1b97e0e205f245f806e564d3505e7 upstream.

With the introduction of PRMT in the ACPI subsystem, the EFI rts
workqueue is no longer the only caller of efi_call_virt_pointer() in the
kernel. This means the EFI runtime services lock is no longer sufficient
to manage concurrent calls into firmware, but also that firmware calls
may occur that are not marshalled via the workqueue mechanism, but
originate directly from the caller context.

For added robustness, and to ensure that the runtime services have 8 KiB
of stack space available as per the EFI spec, introduce a spinlock
protected EFI runtime stack of 8 KiB, where the spinlock also ensures
serialization between the EFI rts workqueue (which itself serializes EFI
runtime calls) and other callers of efi_call_virt_pointer().

While at it, use the stack pivot to avoid reloading the shadow call
stack pointer from the ordinary stack, as doing so could produce a
gadget to defeat it.

9cca110cf8 fs/ntfs3: Fix attr_punch_hole() null pointer derenference
commit 6d5c9e79b726cc473d40e9cb60976dbe8e669624 upstream.

The bug occours due to a misuse of `attr` variable instead of `attr_b`.
`attr` is being initialized as NULL, then being derenfernced
as `attr->res.data_size`.

This bug causes a crash of the ntfs3 driver itself,
If compiled directly to the kernel, it crashes the whole system.

c82fa690da drm/amd/display: Fix COLOR_SPACE_YCBCR2020_TYPE matrix
commit 973a9c810c785ac270a6d50d8cf862b0c1643a10 upstream.

The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is
missing the values for the fourth column of the matrix.

The fourth column of the matrix is essentially just a value that is
added given that the color is 3 components in size.
These values are needed to bias the chroma from the [-1, 1] -> [0, 1]
range.

This fixes color being very green when using Gamescope HDR on HDMI
output which prefers YCC 4:4:4.

87e605b161 drm/amd/display: Fix set scaling doesn's work
commit 040625ab82ce6dca7772cb3867fe5c9eb279a344 upstream.

[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) && dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.

[How]
Correctly update CRTC state when setting scaling property.
