Commit eac69475b0 ("media: rc: igorplugusb: heed coherency
rules") changed the control request storage from an embedded struct to
an allocated pointer so it can obey DMA coherency rules.
However, the driver still passes &ir->request to usb_fill_control_urb().
That points the URB setup packet at the pointer field itself rather than
at the allocated struct usb_ctrlrequest.
USB core then interprets pointer bytes as the setup packet. This can
produce an invalid bRequestType and trigger the control direction warning
reported by syzbot:
usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0
Pass ir->request itself as the setup packet.

Fix to point the error offset correctly for eprobe argument error.
In the cleanup commit 1b8b0cd754 ("tracing/probes: Move event parameter
fetching code to common parser"), due to incorrect backward compatibility
aimed at conforming to the test specifications, the error location was set
to 0 when a non-existent formal parameter was specified for Eprobe.
However, this should be corrected in both the test and the implementation
to point correct error position.

Starting with Rust 1.98.0 (expected 2026-08-20), the target spec will not
support `x86-softfloat` anymore [1]. Instead, `softfloat` should be used,
which is an alias. Otherwise, one gets:
error: error loading target specification: rustc-abi: invalid rustc abi: 'x86-softfloat'. allowed values: 'x86-sse2', 'softfloat' at line 3 column 32

= help: run `rustc --print target-list` for a list of built-in targets
Thus conditionally use one or the other depending on the version.
The alias has existed since Rust 1.95.0 (released 2026-04-16) [2], but
use the newer version instead to avoid changing how the build works for
existing compilers, at least until more testing takes place.

Both GCC [1] and Clang [2] consider the generic version of _THIS_IP_ to
be broken:
#define _THIS_IP_ ({ __label__ __here; __here: (unsigned long)&&__here; })
In particular, the address of a label is only expected to be used with a
computed goto.
While the generic version more or less works today, it is known to be
brittle and may break with current and future optimizations. For
example, Clang -O2 always returns 1 when this function is inlined:
static inline unsigned long get_ip(void)
{ return ({ __label__ __here; __here: (unsigned long)&&__here; }); }
Fix it by overriding _THIS_IP_ in <asm/linkage.h> (which is included by
<linux/instruction_pointer.h>) using an architecture-specific inline asm
version. Additionally, avoiding taking the address of a label prevents
compilers from emitting spurious indirect branch targets (e.g. ENDBR or
BTI) under control-flow integrity schemes.

The existing iris_vpu_dec_comv_size() used VIDEO_MAX_FRAME (32) as
num_comv count unconditionally when calculating the co-located motion
vector (COMV) buffer size. This resulted in an oversized COMV buffer
allocation throughout decode session, wasting memory regardless of
actual number of buffers required.
For VPU3x and VPU4x platforms, introduce iris_vpu3x_4x_dec_comv_size() to
replace iris_vpu_dec_comv_size(). These derive num_comv dynamically, it
uses inst->fw_min_count once the firmware has reported its buffer
requirements, and fallback to output count during initialization before
firmware has communicated its requirements. This aligns the COMV buffer
size to the actual count needed rather than always allocating with fixed
VIDEO_MAX_FRAME value.
Additionally, during iris_vdec_inst_init(), fw_min_count was initialized
to MIN_BUFFERS instead of 0. This masked the fallback logic and caused the
COMV size calculation to use MIN_BUFFERS even before firmware had reported
its actual requirements. Fix this by initializing fw_min_count to 0.
During testing of 1080p AVC, it reduces the COMV buffer size from 32.89MB
to 6.16MB per decode session, significantly reducing memory consumption.

Add the FPS measurement based on the decoder input buffer arrival rate.
The measured FPS is stored per instance and used in frequency calculation

Encoder HFI capabilities on v6 enforce a 16-pixel step for frame and blur
dimensions, which does not reflect actual hardware requirements and can
reject valid userspace configurations.
Relax the step size to 1 while leaving min/max limits unchanged.

get_framesize_raw_nv12() currently adds SZ_4K to the UV plane size and an
additional SZ_8K to the total buffer size. This inflates the calculated
sizeimage and leads userspace to over-allocate buffers without a clear
requirement.
Remove the extra SZ_4K/SZ_8K padding and compute the NV12 size as the sum
of Y and UV planes, keeping the final ALIGN(size, SZ_4K) intact.

Due to a rustc bug [1] the -Cforce-unwind-tables=y flag only emits the
uwtable annotation for functions, but not for the module. This means
that compiler-generated functions such as 'asan.module_ctor' do not
receive the uwtable annotation.
When CONFIG_UNWIND_PATCH_PAC_INTO_SCS is enabled, this leads to boot
failures because the dwarf information emitted for the kasan
constructors is wrong, which causes the SCS boot patching code to
patch the constructor in an illegal manner. Specifically, the paciasp
instruction is patched, but the autiasp instruction is not. This
mismatch leads to a crash when the constructor is called during boot.
==================================================================
BUG: KASAN: global-out-of-bounds in do_basic_setup+0x4c/0x90
Read of size 8 at addr ffffffe3cc7eb488 by task swapper/0/1
Specifically the faulting instruction is the (*fn)() to invoke the
constructor in do_ctors() of the init/main.c file.
Once the fix lands in rustc, this flag can be made conditional on the
rustc version. Note that passing the flag on a rustc with the fix
present has no effect.
[ The fix [1] has landed for Rust 1.98.0 (expected release on
2026-08-20).
Thus add a version check as discussed.

xrep_cow_find_bad_rt() initializes scrub rtgroup state before the
force-rebuild path calls xrep_cow_mark_file_range(). If that call
fails, the code jumps directly to out_rtg, which skips the scrub
rtgroup cleanup and only drops the local rtgroup reference.
Remove the unnecessary jump so the function falls through to out_sr,
ensuring the realtime cursors, lock state, and sr->rtg reference are
released before returning.

xrep_cow_find_bad() returns success after the cleanup labels even if

repair continue with an incomplete bad-file-offset bitmap instead of
stopping at the original error.
The force-rebuild path has a related cleanup problem. If
xrep_cow_mark_file_range() fails, the function returns directly and
skips the scrub AG context and perag cleanup.
Let the force-rebuild path fall through to the existing cleanup code
and return the saved error after cleanup.

xfs_fs_map_blocks() currently passes XFS_BMAPI_ENTIRE to xfs_bmapi_read(),
which causes the bmap code to expand the mapping to cover the entire
extent rather than the requested range.
A single LAYOUTGET request from the client can cause the server to
issue multiple calls to xfs_fs_map_blocks() for different offsets
within the same extent. Because the use of XFS_BMAPI_ENTIRE flag,
these calls can produce overlapping mappings.
As a result, the LAYOUTGET reply sent to the NFS client may contain
overlapping extents. This creates ambiguity in extent selection for a
given file range, which can lead to incorrect device selection,
inconsistent handling of datastate, and ultimately data corruption or
protocol violations on the client side.
Problem discovered with xfstest generic/075 test using NFSv4.2 mount
with SCSI layout.
Fix this by replacing the XFS_BMAPI_ENTIRE flag with '0' so that
xfs_bmapi_read() returns only the mapping for the requested range.

xfs_bmapi_read(). If xfs_bmapi_read() fails, the function currently
still falls through to xfs_bmbt_to_iomap(), which consumes an
uninitialized imap record and may return invalid data to the caller.
Fix this by releasing the data map lock and returning immediately when
xfs_bmapi_read() reports an error. This prevents xfs_bmbt_to_iomap()
from being called with an uninitialized xfs_bmbt_irec.
