ASoC: qcom: Fix AudioReach TDM review findings
Prasad Kumpatla <prasad.kumpatla@oss.qualcomm.com> says:
Address review findings for the recently merged AudioReach TDM backend
support.
The first patch fixes a typo in the newly added QAIF clock ID names by
renaming the LAPSS-prefixed identifiers to LPASS and updating all
corresponding in-tree users.
The remaining patches address issues identified in the AudioReach TDM
configuration and machine-driver paths:
- Zero-initialize AudioReach module configuration structures so
unspecified slot parameters correctly fall back to topology defaults.
- Distinguish between missing TDM configuration and malformed TDM slot
properties by using separate return codes, preventing valid DT
configuration errors from being silently ignored.
- Fix sc8280xp TDM hw_params error handling by properly distinguishing
optional and invalid TDM slot configurations and propagating errors
accordingly.
All issues were reported by Sashiko.

ASoC: qcom: sc8280xp: Fix TDM hw_params error handling
Treat -ENOENT from TDM slot parsing as the optional "configuration not present" case and continue to propagate real configuration errors. Also ignore -ENOTSUPP from optional DAI format and codec sysclk callbacks, apply codec_dai_fmt to codec DAIs on TDM links, and use a signed bclk_freq variable so errors from snd_soc_tdm_params_to_bclk() are handled correctly.

ASoC: qcom: common: Distinguish missing and invalid TDM slot configuration
qcom_snd_parse_dai_tdm_slots() uses -EINVAL for both missing DAI-link TDM configuration and malformed TDM slot properties. As a result, qcom_snd_apply_dai_tdm_slots() silently ignores configuration errors. Return -ENOENT for missing DAI-link configuration and preserve -EINVAL for malformed TDM slot properties.

ASoC: qcom: qdsp6: Zero-initialize AudioReach module config
q6apm_dai_prepare() and q6apm_dai_compr_set_params() build an AudioReach module config on the stack and populate only the fields needed for the stream type. Audio IF media-format setup treats zero slot_mask, nslots_per_frame and slot_width as a request to use the topology defaults. Leave those fields uninitialized and random stack data can override the topology values sent to the DSP. Initialize the whole config structure so omitted fields reliably retain their zero/default meaning.

The QAIF clock IDs were introduced with a LAPSS prefix typo. Rename them to use the existing LPASS naming convention and update all corresponding in-tree users.

sched_ext: Allow ops.cgroup_set_bandwidth() to be sleepable
ops.cgroup_set_bandwidth() is delivered from scx_group_set_bandwidth(), which runs from the cpu.max cgroup interface write path (tg_set_bandwidth()) in process context. scx_group_set_bandwidth() holds percpu_down_read(&scx_cgroup_ops_rwsem), whose read side may sleep. The call site is therefore sleepable, like ops.cgroup_init(). bpf_scx_check_member() rejects a sleepable program on any member not on its allow-list, so a BPF scheduler cannot allocate -- which is sleepable -- when a cgroup gains a cpu.max limit at runtime; it must instead pre-reserve memory for a callback that cannot allocate. Add cgroup_set_bandwidth() to the allow-list so the callback can allocate on demand, and document that it may block. A scheduler must decide at load time whether to mark the callback sleepable, but the allow-list entry is a verifier property with no symbol to probe. Add a compatibility marker whose presence in the kernel's BTF lets userspace detect this support: DEFINE_SCX_COMPAT_MARKER() emits an empty, callerless function, here scx_compat_marker_cgroup_set_bandwidth_may_sleep(). It is __used __retain so neither the compiler nor the linker (under CONFIG_LD_DEAD_CODE_DATA_ELIMINATION) drops it. The markers share the scx_compat_marker_ prefix and are collected near the end of ext.c so more can be added as further capabilities appear.

ASoC: sdw_utils: fix double put_device() on aggregated amps
In aggregation mode with two identical amplifiers, a stress test that repeatedly triggers card unbind/rebind can hit a NULL pointer dereference during the exit path. ctx->amp_dev1 / ctx->amp_dev2 are single shared resources, so the release must be safe against being called more than once. Clear each pointer after put_device() so a second invocation becomes a no-op, this could address NULL pointer dereference issue.

net/mlx5e: do not HW-GRO coalesce small frames
When hardware GRO (SHAMPO) coalesces a small IPv4/TCP segment that was
padded up to the 60-byte minimum Ethernet frame, the trailing padding is
folded into the merged payload causing padding to be delivered
to the user as payload.
Detecting and reproducing the issue: the selftest
tools/testing/selftests/drivers/net/gro.py subtest
hw_ipv4_data_lrg_1byte sends {100, 1} expecting to receive {101}.
In current code, it receives {106} (100 + 1 payload + 5 pad) instead.
This patch avoids giving the user padding as payload by simply not
coalescing small packets (which fails the subtest; the same approach
and behavior as sw gro). This gains code simplicity at the cost of
more computation (passing an extra skb up the stack) for small packets
that could be coalesced.
The threshold is chosen as ETH_ZLEN + 2 * VLAN_HLEN. This is the largest
frame that may still contain minimum-frame padding (+ 2 VLAN tags), so
anything larger is safe to consider for coalesce. (We do not include
ETH_FCS_LEN in that threshold computation as netdev_fix_features()
drops NETIF_F_GRO_HW whenever NETIF_F_RXFCS is set, so retained FCS
can't reach this path.)

net: openvswitch: fix nf_connlabels leak in ovs_ct_init
ovs_ct_init() acquires a connlabels reference before initializing the
conntrack limit state. If ovs_ct_limit_init() fails, its error is returned
directly. The pernet core does not invoke the exit callback for the
operation whose initialization failed, so ovs_ct_exit() cannot drop the
reference.
This leaves labels_used elevated when Open vSwitch pernet registration
fails for an existing network namespace. Subsequent conntrack entries in
that namespace may allocate label extensions even though Open vSwitch
failed to register.
Drop the connlabels reference before returning a conntrack limit
initialization error. ovs_ct_limit_init() already releases its partial
state, and the original error remains unchanged.
This issue was found by a static analysis checker and confirmed by
manual source review.

memblock: updates for 7.3-rc1
Non-urgent fixes:
* Fix calculation of node_spanned_pages when running with kernelcore=mirror
* Properly handle failure to allocate per_cpu_nodestats in
free_area_init_core_hotplug()
* Fix deferred initialization of the memory map for configurations where
node's RAM end is not aligned on PAGES_PER_SECTION
Cleanups:
* Remove redundant pageblock_align() call in free_unused_memmap()
* Remove unnecessary invalid range checks in users of memblock iterators.
Some users of for_each_mem_range() and for_each_mem_pfn_range() verify
that start < end for each range. This is redundant because memblock
iterators guarantee to never return an invalid range
* Stop overlapping zones with kernelcore=mirror and align behaviour of
kernelcore=mirror with other variants of kernelcore=/movablecore=
* Remove redundant updates of numa_nodes_parsed mask in the callers of
numa_add_memblk(), the latter always updates the mask anyway
* Remove unnecessary initialization of pgdat->per_cpu_nodestats to NULL,
the variable is reset to the actual value a few lines below

net: openvswitch: fix flow mask use-after-free on flow deletion
The commit in the Fixes tag below made so flow->mask free is scheduled
via RCU right after it is removed from the flow table. The pointer
stays in the flow structure and it can be accessible while in the same
RCU critical section. This is done to avoid requiring ovs_mutex for
the ovs_flow_free().
However, while removing the flow during processing of CMD_DEL, we do
not take RCU read lock before the removal, and ovs_flow_cmd_fill_info()
uses the flow->mask pointer afterwards. The RCU read lock is taken,
but it's already late at that point. The comment on that line
acknowledges that the lock is cosmetic and doesn't serve a real purpose.
This leads to use-after-free if the RCU grace period passes between
removal and the filling. It is a short race window, but it is there
and can lead to a real crash in case memory allocation for the info
takes a bit longer:

ovs_flow_tbl_remove() must be called after the ovs_flow_cmd_fill_info()
to avoid this race. This also helps with cleaning up the forced cast
and the cosmetic RCU read lock. Before the commit in the Fixes tag the
order did not matter as long as the flow object itself was not freed.
A wider RCU critical section could be another option, but we have a
GFP_KERNEL allocation in the way.

sctp: stop processing a packet once its association is deleted
sctp_endpoint_bh_rcv() looks the association up only when chunk->asoc is
NULL, and caches the result in chunk->asoc and chunk->transport without
taking a reference.
A packet that matches no association is handed to the endpoint, so a peer
can bundle COOKIE ECHO, SHUTDOWN and SHUTDOWN ACK in one packet. The
COOKIE ECHO creates the association, the SHUTDOWN chunk caches it, and
with the outqueue empty the SHUTDOWN ACK reaches sctp_sf_do_9_2_final(),
so the association and its transports are freed.
The endpoint loop has no counterpart to the asoc->base.dead check in
sctp_assoc_bh_rcv(). The next chunk writes to last_time_heard in the freed
transport and is then passed to sctp_do_sm() with the freed association.
The transport is freed through RCU, so this needs the packet to come off
the socket backlog, where the loop runs in task context.
The endpoint loop cannot do the same check: it holds no reference on the
association, so reading asoc->base.dead would itself be a use-after-free.
Mark the packet for discard in the command interpreter, just before it
deletes the association. That is also before sctp_inq_free() releases the
chunk on the association receive path.
sctp_sf_do_5_2_4_dupcook() issues SCTP_CMD_DELETE_TCB for the temporary
association, while the one the packet belongs to stays alive. A restarting
peer can bundle DATA behind its COOKIE ECHO, so compare against
chunk->asoc and leave that case alone.

Merge branch 'dpll-zl3073x-add-ptp-clock-support'
Ivan Vecera says: ==================== dpll: zl3073x: add PTP clock support Add PTP hardware clock support to the zl3073x DPLL driver. Patch 1 scales the poll sleep interval in zl3073x_poll_zero_u8() proportionally to the timeout to avoid excessive bus traffic for the longer PTP-related timeouts. Patch 2 adds low-level channel operations for ToD read/write/adjust, output phase step, delta frequency offset write and TIE write as building blocks for PTP callbacks. Patch 3 registers a PTP clock device for each DPLL channel with gettimex64, settime64, adjtime, adjfine, adjphase and getmaxphase callbacks. Callback availability adapts to the current channel state - adjfine requires NCO pin connected, adjphase uses TIE write when tracking a reference, and adjtime selects the appropriate mechanism automatically. Periodic output support will be added in a follow-up series. ==================== Link: https://patch.msgid.link/20260814082656.306534-1-ivecera@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

dpll: zl3073x: add PTP clock support
Add PTP clock support for the ZL3073x DPLL driver. A PTP clock device is registered for each DPLL channel regardless of the initial channel state, providing gettimex64, settime64, adjtime, adjfine, adjphase and getmaxphase callbacks. Callback availability depends on the current channel state: - adjfine: when NCO pin is connected (returns -EOPNOTSUPP otherwise) - adjphase: available when tracking a reference, uses TIE write - adjtime: always available and uses * phase step for sub-second deltas when NCO pin is connected * TIE write when tracking a reference * plain ToD read-modify-write otherwise - gettime/settime: always available The adjtime callback splits multi-second adjustments into a ToD read-modify-write for the seconds part and a sub-second mechanism (phase step or TIE write) for the remainder. On partial failure where seconds were already committed, success is returned to prevent the PTP servo from retrying and applying seconds again. All PTP callbacks are serialized by the existing per-DPLL zldpll->lock mutex, which is also used by DPLL pin and device callbacks.

dpll: zl3073x: add channel ToD, phase step and TIE operations
Add low-level DPLL channel operations for ToD read/write/adjust, output phase step, delta frequency offset write and TIE (Time Interval Error) write. These serve as building blocks for the PTP clock callbacks added in the next patch. ToD operations use a wait-before-write pattern to avoid blocking after each operation. The tod_ready_wait helper selects the poll timeout based on the current ToD command - write operations use a longer timeout (1000 ms) than reads (30 ms). The ToD read captures system timestamps (ptp_system_timestamp) around the HW command and completion poll to support cross-timestamping. The TIE write operation provides sub-picosecond resolution phase adjustment for modes where the DPLL is tracking a reference (AUTO and REFLOCK). Add output step-time mask to struct zl3073x_dev and zl3073x_dev_out_is_stepped() helper to check if an output participates in step-time operations.

dpll: zl3073x: scale poll interval proportionally to timeout
Replace the fixed 10 us poll sleep in zl3073x_poll_zero_u8() with timeout_us / 50, scaling the sleep interval proportionally to the timeout for all callers. Testing showed that existing callers (mailbox, HWREG, DF read, frequency measurement and phase error polls with 25-50 ms timeouts) typically completed in low hundreds of sleep cycles with the fixed 10 us interval. With the scaled interval the cycle count drops to single digits. The longer PTP-related timeouts (up to 3000 ms for phase step) added in the following patches benefit most, avoiding on the order of 10^5 bus transactions per wait.

ptp: vmclock: prevent read-only mappings from becoming writable
vmclock_miscdev_mmap() rejects writable mappings of the shared vmclock
ABI page with -EROFS, but leaves VM_MAYWRITE set. Userspace can map the
page read-only and then upgrade it to writable with mprotect(), after
which the guest can corrupt the host-written timekeeping data (sequence
counter, UTC time, TSC offset) that the vmclock ABI defines as read-only.
Clear VM_MAYWRITE on the read-only path so the mapping cannot be
upgraded, as i915 does for its read-only objects and as fixed in drm/vc4
(CVE-2026-68445) and drm/panthor (CVE-2024-53071).

ipv4: reject undersized MTUs in ip_do_fragment()
ip_do_fragment() subtracts the IPv4 header length from the effective
MTU and passes the resulting payload MTU to ip_frag_next().
If the effective MTU is smaller than hlen + 8, ip_frag_next() rounds
the fragment payload length down to zero. The fragmentation state then
never makes forward progress: state->left, state->ptr and state->offset
stay unchanged while ip_do_fragment() keeps allocating and transmitting
header-only fragments until the softlockup detector fires.
This is reproducible with a route installed using "mtu lock 20", but it
is also reproducible without route MTU lock, for example by forwarding a
packet to a device whose MTU is 20.
Fix it in ip_do_fragment() by rejecting mtu < hlen + 8 with -EMSGSIZE,
matching the existing IPv6 fragmentation check.

bonding: initialize err for empty target lists
Empty NLA_NESTED attributes are valid, and bonding uses them to clear
the ARP and NS target lists. When either target attribute is empty,
nla_for_each_nested() does not execute, so err retains an uninitialized
value before it is tested. The request can consequently return an
unpredictable error after clearing the targets.
Initialize err to zero so an empty target list completes successfully.
Non-empty lists still propagate errors from __bond_opt_set() unchanged.
This issue was found by a static analysis checker and confirmed by manual
source review.

Pull ACPI support updates from Rafael Wysocki:
"The most significant change here is the elimination of struct
acpi_driver that has no more users in the tree now along with some
documentation related to it, and a follow-up update to set the "no PM"
flag for all ACPI devices that are now only going to play the role of
other devices' "companions" (in analogy with DT nodes).
There is also a significant update of irqchip code related to ACPI
done in order to enable GICv5 IWB ACPI probe ordering detection on
ARM, which involves RISC-V interrupt controller management code
refactoring to extract generic code from it into the common ACPI IRQ
code.
The rest is mostly fixes, including some fallout of the _OSC handling
rework in 7.0, ACPI CPPC library fixes, a workaround for registering
ACPI platform devices with overlapping I/O or memory resources, an
ACPI EC driver fix related to probe deferral on platforms using
HW-reduced ACPI, two ACPI battery driver fixes and a workaround for
handling model numbers with unprintable characters in it, probe error
cleanup and driver unload code path fixes, hardware error reporting
fixes, documentation fixes, and assorted code cleanups all over.

platform/x86: redmi-wmi: report EC state change events
The Redmibook EC/firmware fully handles the keyboard backlight cycle, the OEM preset power mode (Fn+K) and the Fn lock toggle by itself, and sends a WMI event carrying the resulting state in the third payload byte. These events are currently swallowed with KE_IGNORE, so userspace never learns that the state changed and cannot give the user any feedback (OSD), even though the WMI event is the only notification channel for these EC-driven changes. Report them as key presses instead: - keyboard backlight cycle -> KEY_KBDILLUMTOGGLE - OEM preset power mode -> KEY_PERFORMANCE - Fn lock toggle -> KEY_FN_ESC Desktops that only look at the keycode get the usual hotkey behaviour; since sparse-keymap emits MSC_SCAN with the raw payload before the key event, an OSD daemon can additionally recover the exact new state from byte 2 (e.g. backlight Off/Low/High/Auto is 0x00/0x05/0x0a/0x80). Note that the power mode event must keep being read from the WMI device in any case: on the TM2209 the ACPI event handler (EV20) applies the mode change as a side effect of building the event payload for _WED. Tested on Redmi Book Pro 15 2023 (TM2209).

platform/x86: thinkpad_acpi: Fix fan speed reporting on Edge E330
The ThinkPad Edge E330 with H3 firmware uses the non-standard EC fan register block. Without a matching quirk, thinkpad_acpi reads the legacy tachometer registers and reports 0 RPM. Add the H3 BIOS family to TPACPI_FAN_NS so the driver reads the fan period from EC register 0x95 using the existing non-standard reporting path. Tested on a ThinkPad Edge E330 with BIOS H3ET77WW and EC H3EC35WW.

platform/x86: think-lmi: Fix certificate thumbprint sysfs output
cert_thumbprint() already returns the accumulated output length, but
certificate_thumbprint_show() adds that value to count again, making the
next line use the wrong offset. Errors returned by cert_thumbprint() are
also ignored and their negative values added to count.
Assign the total length to count instead and propagate errors correctly.

mlxbf-bootctl: fix the build error with FIELD_PREP()
rsh_log_store() calls the FIELD_PREP() macro without including the
