[ 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.

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.

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.

[ 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.

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.

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).

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.

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.

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__.

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.

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.

[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.

commit 5bfdd3c654bd879bff50c2e85e42f85ae698b42f upstream.
Commit ba47f97a18f2 ("serial: core: remove baud_rates when serial console
setup") changed uart_set_options to select the correct baudrate
configuration based on the absolute error between requested baudrate and
available standard baudrate settings.
Prior to that commit the baudrate was selected based on which predefined
standard baudrate did not exceed the requested baudrate.
This change of selection logic was never reflected in the atmel serial
driver. Thus the comment left in the atmel serial driver is no longer
accurate.
Additionally the manual rounding up described in that comment and applied
via (quot - 1) requests an incorrect baudrate. Since uart_set_options uses
tty_termios_encode_baud_rate to determine the appropriate baudrate flags
this can cause baudrate selection to fail entirely because
tty_termios_encode_baud_rate will only select a baudrate if relative error
between requested and selected baudrate does not exceed +/-2%.
Fix that by requesting actual, exact baudrate used by the serial.

A local variable sg is used to store scatterlist pointer in
pch_dma_tx_complete(). The for loop doing Tx byte accounting before
dma_unmap_sg() alters sg in its increment statement. Therefore, the

dma_map_sg().
To fix the problem, use priv->sg_tx_p directly in dma_unmap_sg()
instead of the local variable.
