Pull sh fix from John Paul Adrian Glaubitz:
"The ZERO_PAGE consolidation in v7.1, introduced a regression on sh
which made these systems unbootable.
The problem was that on sh, the initial boot parameters were

Miscellaneous scheduler fixes:
- Fix the delayed dequeue negative lag increase fix in the
fair scheduler (Peter Zijlstra)
- Fix wakeup_preempt_fair() to do proper delayed dequeue
(Vincent Guittot)
- Clear sched_entity::rel_deadline when initializing
forked entities, which bug can cause all tasks to be
EEVDF-ineligible, causing a NULL pointer dereference
crash in pick_next_entity() (Zicheng Qu)

Description for this pull request:
- Fix a NULL pointer dereference in ntfs_index_walk_down() by validating
index block allocation.
- Fix a memory leak of the symlink target string in
ntfs_reparse_set_wsl_symlink() during error paths.
- Prevent VCN overflow and validate lowest_vcn in
ntfs_mapping_pairs_decompress() to avoid runlist corruption.
- Fix a page reference leak in ntfs_write_iomap_end_resident() when
attribute search context allocation fails.
- Fix an invalid PTR_ERR() usage on a valid folio pointer in
__ntfs_bitmap_set_bits_in_run().
- Correct directory link counting by dropping nlink only when the MFT
record link count reaches zero for WIN32/DOS aliases.
- Fix an uninitialized variable usage in ntfs_mapping_pairs_decompress()
by returning an error pointer directly.

Assorted arm64, ACPI and kselftest fixes for 7.1-rc2:
- Avoid writing an uninitialised stack variable to POR_EL0 on
sigreturn if the poe_context record is absent
- Reserve one more page for the early 4K-page kernel mapping to cover
the extra [_text, _stext) split introduced by the non-executable
read-only mapping
- Force the arch_local_irq_*() wrappers to be __always_inline so that
noinstr entry and idle paths cannot call out-of-line, instrumentable
copies
- Fix potential sign extension in the arm64 SCS unwinder's DWARF
advance_loc4 decoding
- Tolerate arm64 ACPI platforms with only WFI and no deeper PSCI idle
states, restoring cpuidle registration on such systems
- Include the UAPI <asm/ptrace.h> header in the arm64 GCS libc test
rather than carrying a duplicate struct user_gcs definition (the
original #ifdef NT_ARM_GCS was wrong to cover the structure
definition as it would be masked out if the toolchain defined it)

futex: Drop CLONE_THREAD requirement for private default hash alloc
Currently need_futex_hash_allocate_default() depends on strict pthread
semantics, abusing CLONE_THREAD. This breaks the non-concurrency
assumptions when doing the mm->futex_ref pcpu allocations, leading to
bugs[0] when sharing the mm in other ways; ie:
BUG: KASAN: slab-use-after-free in futex_hash_put
... where the +1 bias can end up on a percpu counter that mm->futex_ref
no longer points at.
Loosen the check to cover any CLONE_VM clone, except vfork(). Excluding
vfork keeps the existing paths untouched (no overhead), and we can't
race in the first place: either the parent is suspended and the child
runs alone, or mm->futex_ref is already allocated from an earlier
CLONE_VM.

For 4K pages, the early kernel mapping may use 2MB block entries but the
kernel segments are only 64KB aligned. Segment boundaries that fall
within a 2MB block therefore require a PTE table so that different
attributes can be applied on either side of the boundary.
KERNEL_SEGMENT_COUNT still correctly counts the five permanent kernel
VMAs registered by declare_kernel_vmas(). However, since commit

Include <asm/ptrace.h> in libc-gcs.c for the definition of struct
user_gcs from the uAPI headers, and remove the redundant definition in
gcs-util.h. This fixes a compilation error on systems where the

mm: memcontrol: fix rcu unbalance in get_non_dying_memcg_end()
Currently, get_non_dying_memcg_start() and get_non_dying_memcg_end() both
evaluate cgroup_subsys_on_dfl(memory_cgrp_subsys) independently to
determine whether to acquire or release the RCU read lock.
However, the result of cgroup_subsys_on_dfl() can change dynamically at
runtime due to cgroup hierarchy rebinding (e.g., when the memory
controller is moved between cgroup v1 and v2 hierarchies). This can cause
the following warning:

io_uring/tw: serialize ctx->retry_llist with ->uring_lock
The DEFER_TASKRUN local task work paths all run under ctx->uring_lock,
which serializes them with each other and with the rest of the ring's
hot paths. io_move_task_work_from_local() is the exception - it's called
from io_ring_exit_work() on a kworker without holding the lock and from
the iopoll cancelation side right after dropping it.
->work_llist is fine with this, as it's only ever updated via the
expected paths. But the ->retry_llist is updated while runing, and hence
it could potentially race between normal task_work running and the
task-has-exited shutdown path.
Simply grab ->uring_lock while moving the local work to the fallback
list for exit purposes, which nicely serializes it across both the
normal additions and the exit prune path.

net: tls: fix strparser anchor skb leak on offload RX setup failure
When tls_set_device_offload_rx() fails at tls_dev_add(), the error path calls tls_sw_free_resources_rx() to clean up the SW context that was initialized by tls_set_sw_offload(). This function calls tls_sw_release_resources_rx() (which stops the strparser via tls_strp_stop()) and tls_sw_free_ctx_rx() (which kfrees the context), but never frees the anchor skb that was allocated by alloc_skb(0) in tls_strp_init(). Note that tls_sw_free_resources_rx() is exclusively used for this "failed to start offload" code path, there's no other caller. The leak did not exist before commit |

Merge branch 'intel-wired-lan-update-2026-04-27-ice-iavf'
Jacob Keller says: ==================== Intel Wired LAN Update 2026-04-27 (ice, iavf) Petr Oros from RedHat has accumulated a number of fixes for the Intel ice and iavf drivers, bundled together in this series. First, a series of 4 fixes to resolve issues with the iavf driver logic for handling VLAN filters. This includes keeping VLAN filters while the interface is brought down, waiting for confirmation on filter deletion before deleting filters from the driver tracking structures, and handling the VIRTCHNL_OP_ADD_VLAN for the old v1 VLAN_ADD command. A fix for a crash in ice_reset_all_vfs(), properly checking for errors when ice_vf_rebuild_vsi() fails. A fix for a possible infinite recursion in ice_cfg_tx_topo() that occurs when trying to apply invalid Tx topology configuration. A fix to initialize the SMA pins in the DPLL subsystem properly. A fix to change the SMA and U.FL pin state for paired pins, ensuring that all flows changing one pin will also update its shared pin appropriately. A preparatory patch to export __dpll_pin_change_ntf() so that drivers can notify pin changes while already holding the dpll_lock. A fix to ensure DPLL notifications are sent for the software-controlled pins which wrap the physical CGU input/output pins. A fix to add DPLL notifications for peer pins when changing the SMA or U.FL pins, ensuring DPLL subsystem is notified about the paired connected pins.

ice: add dpll peer notification for paired SMA and U.FL pins
SMA and U.FL pins share physical signal paths in pairs (SMA1/U.FL1 and
SMA2/U.FL2). When one pin's state changes via a PCA9575 GPIO write,
the paired pin's state also changes, but no notification is sent for
the peer pin. Userspace consumers monitoring the peer via dpll netlink
subscribe never learn about the update.
Add ice_dpll_sw_pin_notify_peer() which sends a change notification for
the paired SW pin. Call it from ice_dpll_pin_sma_direction_set(),
ice_dpll_sma_pin_state_set(), and ice_dpll_ufl_pin_state_set() after
pf->dplls.lock is released. Use __dpll_pin_change_ntf() because
dpll_lock is still held by the dpll netlink layer (dpll_pin_pre_doit).

ice: fix SMA and U.FL pin state changes affecting paired pin
SMA and U.FL pins share physical signal paths in pairs (SMA1/U.FL1 and
SMA2/U.FL2) controlled by the PCA9575 GPIO expander. Each pair can
only have one active pin at a time: SMA1 output and U.FL1 output share
the same CGU output, SMA2 input and U.FL2 input share the same CGU
input. The PCA9575 register bits determine which connector in each
pair owns the signal path.
The driver does not account for this pairing in two places:
ice_dpll_ufl_pin_state_set() modifies PCA9575 bits and disables the
backing CGU pin without checking whether the U.FL pin is currently
active. Disconnecting an already inactive U.FL pin flips bits that
the paired SMA pin relies on, breaking its connection.
ice_dpll_sma_direction_set() does not propagate direction changes to
the paired U.FL pin. For SMA2/U.FL2 the ICE_SMA2_UFL2_RX_DIS bit is
never managed, so U.FL2 stays disconnected after SMA2 switches to
output. For both pairs the backing CGU pin of the U.FL side is never
enabled when a direction change activates it, so userspace sees the
pin as disconnected even though the routing is correct.
Fix by guarding the U.FL disconnect path against inactive pins and by
updating the paired U.FL pin fully on SMA direction changes: manage
ICE_SMA2_UFL2_RX_DIS for the SMA2/U.FL2 pair and enable the backing
CGU pin whenever the peer becomes active.

ice: fix missing SMA pin initialization in DPLL subsystem
The DPLL SMA/U.FL pin redesign introduced ice_dpll_sw_pin_frequency_get()
which gates frequency reporting on the pin's active flag. This flag is
determined by ice_dpll_sw_pins_update() from the PCA9575 GPIO expander
state. Before the redesign, SMA pins were exposed as direct HW
input/output pins and ice_dpll_frequency_get() returned the CGU
frequency unconditionally — the PCA9575 state was never consulted.
The PCA9575 powers on with all outputs high, setting ICE_SMA1_DIR_EN,
ICE_SMA1_TX_EN, ICE_SMA2_DIR_EN and ICE_SMA2_TX_EN. Nothing in the
driver writes the register during initialization, so
ice_dpll_sw_pins_update() sees all pins as inactive and
ice_dpll_sw_pin_frequency_get() permanently returns 0 Hz for every
SW pin.
Fix this by writing a default SMA configuration in
ice_dpll_init_info_sw_pins(): clear all SMA bits, then set SMA1 and
SMA2 as active inputs (DIR_EN=0) with U.FL1 output and U.FL2 input
disabled. Each SMA/U.FL pair shares a physical signal path so only
one pin per pair can be active at a time. U.FL pins still report
frequency 0 after this fix: U.FL1 (output-only) is disabled by
ICE_SMA1_TX_EN which keeps the TX output buffer off, and U.FL2
(input-only) is disabled by ICE_SMA2_UFL2_RX_DIS. They can be
activated by changing the corresponding SMA pin direction via dpll
netlink.

ice: fix infinite recursion in ice_cfg_tx_topo via ice_init_dev_hw
On certain E810 configurations where firmware supports Tx scheduler topology switching (tx_sched_topo_comp_mode_en), ice_cfg_tx_topo() may need to apply a new 5-layer or 9-layer topology from the DDP package. If the AQ command to set the topology fails (e.g. due to invalid DDP data or firmware limitations), the global configuration lock must still be cleared via a CORER reset. Commit |

ice: fix NULL pointer dereference in ice_reset_all_vfs()
ice_reset_all_vfs() ignores the return value of ice_vf_rebuild_vsi().
When the VSI rebuild fails (e.g. during NVM firmware update via
nvmupdate64e), ice_vsi_rebuild() tears down the VSI on its error path,
leaving txq_map and rxq_map as NULL. The subsequent unconditional call
to ice_vf_post_vsi_rebuild() leads to a NULL pointer dereference in
ice_ena_vf_q_mappings() when it accesses vsi->txq_map[0].
The single-VF reset path in ice_reset_vf() already handles this
correctly by checking the return value of ice_vf_reconfig_vsi() and
skipping ice_vf_post_vsi_rebuild() on failure.
Apply the same pattern to ice_reset_all_vfs(): check the return value
of ice_vf_rebuild_vsi() and skip ice_vf_post_vsi_rebuild() and
ice_eswitch_attach_vf() on failure. The VF is left safely disabled
(ICE_VF_STATE_INIT not set, VFGEN_RSTAT not set to VFACTIVE) and can
be recovered via a VFLR triggered by a PCI reset of the VF
(sysfs reset or driver rebind).
Note that this patch does not prevent the VF VSI rebuild from failing
during NVM update — the underlying cause is firmware being in a
transitional state while the EMP reset is processed, which can cause
Admin Queue commands (ice_add_vsi, ice_cfg_vsi_lan) to fail. This
patch only prevents the subsequent NULL pointer dereference that
crashes the kernel when the rebuild does fail.

iavf: add VIRTCHNL_OP_ADD_VLAN to success completion handler
The V1 ADD_VLAN opcode had no success handler; filters sent via V1
stayed in ADDING state permanently. Add a fallthrough case so V1
filters also transition ADDING -> ACTIVE on PF confirmation.
Critically, add an `if (v_retval) break` guard: the error switch in
iavf_virtchnl_completion() does NOT return after handling errors,
it falls through to the success switch. Without this guard, a
PF-rejected ADD would incorrectly mark ADDING filters as ACTIVE,
creating a driver/HW mismatch where the driver believes the filter
is installed but the PF never accepted it.
For V2, this is harmless: iavf_vlan_add_reject() in the error
block already kfree'd all ADDING filters, so the success handler
finds nothing to transition.

iavf: wait for PF confirmation before removing VLAN filters
The VLAN filter DELETE path was asymmetric with the ADD path: ADD
waits for PF confirmation (ADD -> ADDING -> ACTIVE), but DELETE
immediately frees the filter struct after sending the DEL message
without waiting for the PF response.
This is problematic because:
- If the PF rejects the DEL, the filter remains in HW but the driver
has already freed the tracking structure, losing sync.
- Race conditions between DEL pending and other operations
(add, reset) cannot be properly resolved if the filter struct
is already gone.
Add IAVF_VLAN_REMOVING state to make the DELETE path symmetric:
REMOVE -> REMOVING (send DEL) -> PF confirms -> kfree
-> PF rejects -> ACTIVE
In iavf_del_vlans(), transition filters from REMOVE to REMOVING
instead of immediately freeing them. The new DEL completion handler
in iavf_virtchnl_completion() frees filters on success or reverts
them to ACTIVE on error.
Update iavf_add_vlan() to handle the REMOVING state: if a DEL is
pending and the user re-adds the same VLAN, queue it for ADD so
it gets re-programmed after the PF processes the DEL.
The !VLAN_FILTERING_ALLOWED early-exit path still frees filters
directly since no PF message is sent in that case.
Also update iavf_del_vlan() to skip filters already in REMOVING
state: DEL has been sent to PF and the completion handler will
free the filter when PF confirms. Without this guard, the sequence
DEL(pending) -> user-del -> second DEL could cause the PF to return
an error for the second DEL (filter already gone), causing the
completion handler to incorrectly revert a deleted filter back to
ACTIVE.
