io_uring/poll: fix signed comparison in io_poll_get_ownership()
io_poll_get_ownership() uses a signed comparison to check whether
poll_refs has reached the threshold for the slowpath:
if (unlikely(atomic_read(&req->poll_refs) >= IO_POLL_REF_BIAS))
atomic_read() returns int (signed). When IO_POLL_CANCEL_FLAG
(BIT(31)) is set in poll_refs, the value becomes negative in
signed arithmetic, so the >= 128 comparison always evaluates to
false and the slowpath is never taken.
Fix this by casting the atomic_read() result to unsigned int
before the comparison, so that the cancel flag is treated as a
large positive value and correctly triggers the slowpath.
Fixes:

New command-line options: --soc-slider-balance <value> --soc-slider-offset <value> --platform-profile <name> These options allow control of the processor thermal SOC slider balance and offset through the processor_thermal_soc_slider module, as well as the platform profile class interface. When no update flags are set, the tool now also prints the current SOC slider and platform profile values alongside existing MSR output.

selftests/bpf: Test small task local data allocation
Make sure task local data is working correctly for different allocation sizes.

selftests/bpf: Fix tld_get_data() returning garbage data
BPF side tld_get_data() currently may return garbage when tld_data_u is not aligned to page_size. This can happen when small amount of memory is allocated for tld_data_u. The misalignment is supposed to be allowed and the BPF side will use tld_data_u->start to reference the tld_data_u in a page. However, since "start" is within tld_data_u, there is no way to know the correct "start" in the first place. As a result, BPF programs will see garbage data. The selftest did not catch this since it tries to allocate the maximum amount of data possible (i.e., a page) such that tld_data_u->start is always correct. Fix it by moving tld_data_u->start to tld_data_map->start. The original field is now renamed as unused instead of removing it because BPF side tld_get_data() views off = 0 returned from tld_fetch_key() as uninitialized.

However, the finalize path copies the JITed code via architecture text patching routines (__text_poke on arm64, patch_text_nosync on riscv) that already perform a full flush_icache_range() internally. The subsequent bpf_flush_icache() repeats the same cache maintenance on the same range. Remove the redundant flush and the now-unused bpf_flush_icache() definitions on both architectures. ==================== Link: https://patch.msgid.link/20260413191111.3426023-1-puranjay@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

bpf: Fix use-after-free in arena_vm_close on fork
arena_vm_open() only bumps vml->mmap_count but never registers the
child VMA in arena->vma_list. The vml->vma always points at the
parent VMA, so after parent munmap the pointer dangles. If the child
then calls bpf_arena_free_pages(), zap_pages() reads the stale
vml->vma triggering use-after-free.
Fix this by preventing the arena VMA from being inherited across
fork with VM_DONTCOPY, and preventing VMA splits via the may_split
callback.
Also reject mremap with a .mremap callback returning -EINVAL. A
same-size mremap(MREMAP_FIXED) on the full arena VMA reaches
copy_vma() through the following path:
check_prep_vma() - returns 0 early: new_len == old_len
skips VM_DONTEXPAND check
prep_move_vma() - vm_start == old_addr and
vm_end == old_addr + old_len
so may_split is never called
move_vma()
copy_vma_and_data()
copy_vma()
vm_area_dup() - copies vm_private_data (vml pointer)
vm_ops->open() - bumps vml->mmap_count
vm_ops->mremap() - returns -EINVAL, rollback unmaps new VMA
The refcount ensures the rollback's arena_vm_close does not free
the vml shared with the original VMA.

bpf, arm64: Fix off-by-one in check_imm signed range check
check_imm(bits, imm) is used in the arm64 BPF JIT to verify that
a branch displacement (in arm64 instruction units) fits into the
signed N-bit immediate field of a B, B.cond or CBZ/CBNZ encoding
before it is handed to the encoder. The macro currently tests for
(imm > 0 && imm >> bits) || (imm < 0 && ~imm >> bits) which admits
values in [-2^N, 2^N) — effectively a signed (N+1)-bit range. A
signed N-bit field only holds [-2^(N-1), 2^(N-1)), so the check
admits one extra bit of range on each side.
In particular, for check_imm19(), values in [2^18, 2^19) slip past
the check but do not fit into the 19-bit signed imm19 field of
B.cond. aarch64_insn_encode_immediate() then masks the raw value
into the 19-bit field, setting bit 18 (the sign bit) and flipping
a forward branch into a backward one. Same class of issue exists
for check_imm26() and the B/BL encoding. Shift by (bits - 1)
instead of bits so the actual signed N-bit range is enforced.

bpf, arm64: Reject out-of-range B.cond targets
aarch64_insn_gen_cond_branch_imm() calls label_imm_common() to compute a 19-bit signed byte offset for a conditional branch, but unlike its siblings aarch64_insn_gen_branch_imm() and aarch64_insn_gen_comp_branch_imm(), it does not check whether label_imm_common() returned its out-of-range sentinel (range) before feeding the value to aarch64_insn_encode_immediate(). aarch64_insn_encode_immediate() unconditionally masks the value with the 19-bit field mask, so an offset that was rejected by label_imm_common() gets silently truncated. With the sentinel value SZ_1M, the resulting field ends up with bit 18 (the sign bit of the 19-bit signed displacement) set, and the CPU decodes it as a ~1 MiB *backward* branch, producing an incorrectly targeted B.cond instruction. For code-gen locations like the emit_bpf_tail_call() this function is the only barrier between an overflowing displacement and a silently miscompiled branch. Fix it by returning AARCH64_BREAK_FAULT when the offset is out of range, so callers see a loud failure instead of a silently misencoded branch. validate_code() scans the generated image for any AARCH64_BREAK_FAULT and then lets the JIT fail.

accel/amdxdna: Fix fatal_error_info layout in firmware interface
Adjust struct fatal_error_info to match the expected driver/firmware

The structure is used to retrieve debug information from firmware when
a command becomes stuck on the device. The reserved field currently
uses 128 u32 entries, which makes the structure larger than intended
and causes the layout to no longer match the firmware definition.
Reduce the reserved array size from 128 to 127 entries so the
structure matches the expected interface format.

sched_ext: Changes for v7.1
- Cgroup sub-scheduler groundwork. Multiple BPF schedulers can be attached to cgroups and the dispatch path is made hierarchical. This involves substantial restructuring of the core dispatch, bypass, watchdog, and dump paths to be per-scheduler, along with new infrastructure for scheduler ownership enforcement, lifecycle management, and cgroup subtree iteration. The enqueue path is not yet updated and will follow in a later cycle. - scx_bpf_dsq_reenq() generalized to support any DSQ including remote local DSQs and user DSQs. Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched to local DSQs either run immediately or get reenqueued back through ops.enqueue(), giving schedulers tighter control over queueing latency. Also useful for opportunistic CPU sharing across sub-schedulers. - ops.dequeue() was only invoked when the core knew a task was in BPF data structures, missing scheduling property change events and skipping callbacks for non-local DSQ dispatches from ops.select_cpu(). Fixed to guarantee exactly one ops.dequeue() call when a task leaves BPF scheduler custody. - Kfunc access validation moved from runtime to BPF verifier time, removing runtime mask enforcement. - Idle SMT sibling prioritization in the idle CPU selection path. - Documentation, selftest, and tooling updates.

drm/i915: Track fence region ID in plane state
Get rid of the needlessly complicated PLANE_HAS_FENCE +
intel_parent_vma_fence_id() dance by simply tracking the
fence_id directly in the plane state.
v2: Don't request the redundant fence for fbdev (Jani)
Assign *out_fence_id with '=' instead of '|=' (Sashiko,Jani)

Merge branch 'bpf-arg-tracking-for-imprecise-multi-offset-bpf_st-stx'
Eduard Zingerman says: ==================== bpf: arg tracking for imprecise/multi-offset BPF_ST/STX When the static arg tracking analysis encounters a store through a pointer with imprecise or multi-offset destination, it must use weak updates (join) instead of strong updates (overwrite) for the affected at_stack slots. At runtime only one slot is actually written; the others retain their old values. Two cases are addressed: - BPF_STX, handled by spill_to_stack(). It was gated on `dst_is_local_fp = (frame == depth)`, which missed ARG_IMPRECISE pointers entirely. - BPF_ST, handled by clear_stack_for_all_offs(). It delegates to clear_overlapping_stack_slots() which unconditionally set `at_stack[i] = none`. Change to `at_stack[i] = join(old, none)` when multiple candidate slots exist (cnt != 1), so that untouched slots preserve their tracked values. No veristat diff compared to current master when tested on selftests, sched_ext, cilium and a set of Meta internal programs. This addresses issues reported by sashiko for patch #7 in [1]. [1] https://sashiko.dev/#/patchset/20260410-patch-set-v4-0-5d4eecb343db%40gmail.com Changelog: v2 -> v3: - Use check_add_overflow() in arg_add() (Alexei). - Add missing fixes tag (CI bot). - Remove unused __imm in the selftest (sashiko). v1 -> v2: - Delete the OFF_IMPRECISE constant, always rely on arg_track->cnt == 0 as a marker the offset is imprecise. (Alexei). - Squash all patches together to simplify backporting to 'bpf' branch (Alexei). v1: https://lore.kernel.org/bpf/20260413-stacklive-fixes-v1-0-9f48a9999d6e@gmail.com/T/ v2: https://lore.kernel.org/bpf/20260413-stacklive-fixes-v2-0-ff91c4f8d273@gmail.com/T/ --- ==================== Link: https://patch.msgid.link/20260413-stacklive-fixes-v2-0-398e126e5cf3@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

selftests/bpf: arg tracking for imprecise/multi-offset BPF_ST/STX
Add test cases for clear_stack_for_all_offs and dst_is_local_fp handling of multi-offset and ARG_IMPRECISE stack pointers: - st_imm_join_with_multi_off: BPF_ST through multi-offset dst should join at_stack with none instead of overwriting both candidate slots. - st_imm_join_with_imprecise_off: BPF_ST through offset-imprecise dst should join at_stack with none instead of clearing all slots. - st_imm_join_with_single_off: a canary checking that BPF_ST with a known offset overwrites slot instead of joining. - imprecise_dst_spill_join: BPF_STX through ARG_IMPRECISE dst should be recognized as a local spill and join at_stack with the written value.

bpf: fix arg tracking for imprecise/multi-offset BPF_ST/STX
BPF_STX through ARG_IMPRECISE dst should be recognized as a local
spill and join at_stack with the written value. For example,
consider the following situation:
// r1 = ARG_IMPRECISE{mask=BIT(0)|BIT(1)}
*(u64 *)(r1 + 0) = r8
Here the analysis should produce an equivalent of
at_stack[*] = join(old, r8)
BPF_ST through multi-offset or imprecise dst should join at_stack with
none instead of overwriting the slots. For example, consider the
following situation:
// r1 = ARG_IMPRECISE{mask=BIT(0)|BIT(1)}
*(u64 *)(r1 + 0) = 0
Here the analysis should produce an equivalent of
at_stack[*r1] = join(old, none).
Move the definition of the clear_overlapping_stack_slots() in order to
have __arg_track_join() visible. Remove the OFF_IMPRECISE constant to
avoid having two ways to express imprecise offset.
Only 'offset-imprecise {frame=N, cnt=0}' remains.
Fixes:

ACPI: video: Move Lenovo Legion S7 15ACH6 quirk to the right section
The video_detect_dmi_table[] quirk table has different sections for
different types of problems.
The Lenovo Legion S7 15ACH6 quirk deals with a non working nvidia_wmi_ec
backlight, move it to the section with the other models with this problem.
While at it also add a comment with the laptop model name to the quirk.

ACPI: video: Add backlight=native quirk for Dell OptiPlex 7770 AIO
The Dell OptiPlex 7770 AIO needs the same quirk as the 7760 AIO. The
backlight can be controlled with the native controller, intel_backlight,
but not with dell_uart_backlight.
I dumped the DSDT using acpidump, acpixtract and iasl, and confirmed
that it contains the DELL0501 device. When loading the
dell_uart_backlight driver with `rmmod dell_uart_backlight`, `modprobe
dell_uart_backlight dyndbg`, it reports "Firmware version: GL_Re_V18".

Add a trivial stub that can be used in place of the real function.

ACPI: scan: Use acpi_dev_put() in object add error paths
After acpi_init_device_object(), the lifetime of struct acpi_device is managed by the driver core through reference counting. Both acpi_add_power_resource() and acpi_add_single_object() call acpi_init_device_object() and then invoke acpi_device_add(). If that fails, their error paths call the release callback directly instead of dropping the device reference through acpi_dev_put(). This bypasses the normal device lifetime rules and frees the object without releasing the reference acquired by device_initialize(), which may lead to a refcount leak. The issue was identified by a static analysis tool I developed and confirmed by manual review. Fix both error paths by using acpi_dev_put() and let the release callback handle the final cleanup.

hv: Select CONFIG_SYSFB only for CONFIG_HYPERV_VMBUS
Hyperv's sysfb access only exists in the VMBUS support. Therefore
only select CONFIG_SYSFB for CONFIG_HYPERV_VMBUS. Avoids sysfb code
on systems that don't need it.

ALSA: usb-audio: Tidy up error check for processing unit
There are two duplicated code paths calling get_min_max() with the same arguments in build_audio_procunit(). This once led to a failure to notice a code path that caused the `err' variable uninitialized when adding error checks for callers of get_min_max*() [1]. Move cases in the switch-case statement to tidy up the error check by merging the duplicated code paths together with a fallthrough attribute. This also eliminates the `err = 0' lines and aggregates the error check along with the corresponding call together, so that the intent of these code paths is clearer. The refactor also has an interesting effect that shrinks the .text size by 16 bytes (GCC 15 amd64). It seems that the compiler was unable to perform dead code elimination for the `err = 0' paths before.
