04ff821074 dt-bindings: bluetooth: qcom,wcn7850-bt: Split to separate schema
One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,wcn7850-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.  Re-shuffle few properties to alphabetical order
while moving them and drop redundant enable-gpios description.

This makes the source qualcomm-bluetooth.yaml binding empty, thus drop
it making entire change a variant of file rename.

6e62e4016f dt-bindings: bluetooth: qcom,wcn6855-bt: Deprecate old supplies
Commit 5f4f954bba ("dt-bindings: bluetooth: bring the HW description
closer to reality for wcn6855") changed the binding to new description
with a Power Management Unit (PMU), thus certain power-controller
properties are considered deprecated and are part of that PMUs binding.

Deprecate them to mark clearly that new PMU-based approach is preferred.

0e2a6af810 Bluetooth: Fix using PHYs bitfields as PHY value
This renames the PHY fields in bt_iso_io_qos to PHYs (plural) since it
represents a bitfield where multiple PHYs can be set and make the same
change also to HCI_OP_LE_SET_CIG_PARAMS since both c_phy and p_phy
fields are bitfields.

This also fixes the assumption that hci_evt_le_cis_established PHYs
fields are compatible with bt_iso_io_qos, they are not, the fields in
hci_evt_le_cis_established represent just a single PHY value so they
need to be converted to bitfield when set in bt_iso_io_qos.

49d0901e26 Bluetooth: hci_conn: use mod_delayed_work for active mode timeout
hci_conn_enter_active_mode() uses queue_delayed_work() with the
intention that the work will run after the given timeout. However,
queue_delayed_work() does nothing if the work is already queued, so
depending on the link policy we may end up putting the connection
into idle mode every hdev->idle_timeout ms.

Use mod_delayed_work() instead so the work is queued if not already
queued, and the timeout is updated otherwise.

fce1a9244a Bluetooth: hci_qca: Fix SSR (SubSystem Restart) fail when BT_EN is pulled up by hw
On QCS9075 and QCA8275 platforms, the BT_EN pin is always pulled up by hw
and cannot be controlled by the host. As a result, in case of a firmware
crash, the host cannot trigger a cold reset. Instead, the BT controller
performs a warm restart on its own, without reloading the firmware.

This leads to the controller remaining in IBS_WAKE state, while the host
expects it to be in sleep mode. The mismatch causes HCI reset commands
to time out. Additionally, the driver does not clear internal flags
QCA_SSR_TRIGGERED and QCA_IBS_DISABLED, which blocks the reset sequence.
If the SSR duration exceeds 2 seconds, the host may enter TX sleep mode
due to tx_idle_timeout, further preventing recovery. Also, memcoredump_flag
is not cleared, so only the first SSR generates a coredump.

Tell the driver that the BT controller has undergone a proper restart sequence:

- Clear QCA_SSR_TRIGGERED and QCA_IBS_DISABLED flags after SSR.
- Add a 50ms delay to allow the controller to complete its warm reset.
- Reset tx_idle_timer to prevent the host from entering TX sleep mode.
- Clear memcoredump_flag to allow multiple coredump captures.

Apply these steps only when HCI_QUIRK_NON_PERSISTENT_SETUP is not set,
which indicates that BT_EN is defined in DTS and cannot be toggled.

Refer to the comment in include/net/bluetooth/hci.h for details on
HCI_QUIRK_NON_PERSISTENT_SETUP.

Patch 6 removes a duplicated helper from xt_time extension, we can
use an existing helper for this, from Jinjie Ruan.

Patch 7 adds an rhashtable to nfnetink_queue to speed up out-of-order
verdict processing.  Before this list walk was required due to in-order
design assumption.

e19079adcd netfilter: nfnetlink_queue: optimize verdict lookup with hash table
The current implementation uses a linear list to find queued packets by
ID when processing verdicts from userspace. With large queue depths and
out-of-order verdicting, this O(n) lookup becomes a significant
bottleneck, causing userspace verdict processing to dominate CPU time.

Replace the linear search with a hash table for O(1) average-case
packet lookup by ID. A global rhashtable spanning all network
namespaces attributes hash bucket memory to kernel but is subject to
fixed upper bound.

aba0138eb7 net: ethernet: neterion: s2io: remove unused driver
The s2io driver supports Exar (formerly Neterion and S2io) PCI-X 10
Gigabit Ethernet cards. Hardware supporting PCI-X has not been
manufactured in years. On x86, it was quickly replaced by PCIe. While
it stuck around longer on POWER hardware, the last POWER hardware to
support it was POWER7, which is not supported by ppc64le Linux
distributions. The last supported mainstream ppc64 Linux distribution
was RHEL 7; while it is still supported under ELS, ELS is only
available for x86 and IBM Z. It is possible to use many PCI-X cards in
standard PCI slots (which are still available on new motherboards), but
it does not make sense to do so for 10 Gigabit Ethernet because the
maximum bandwidth of standard PCI is only 1067 Mbps. It is therefore
highly unlikely that this driver is still being used. Remove the
driver, and move the former maintainer to the CREDITS file (restoring
credit for the vxge driver, which was removed in commit f05643a0f6
("eth: remove neterion/vxge").

70de46740b selftests: drv-net: psp: fix test flakes from racy connection close
There is a bug in assoc_sk_only_mismatch() and
assoc_sk_only_mismatch_tx() that creates a race condition which
triggers test flakes in later test cases e.g. data_send_bad_key().

The problem is that the client uses the "conn clr" rpc to setup a data
connection with psp_responder, but never uses a matching "data close"
rpc. This creates a race condition where if the client can queue
another data sock request, like in data_send_bad_key(), before the
server can accept the old connection from the backlog we end up in a
situation where we have two connections in the backlog: one for the
closed connection we have received a FIN for, and one for the new PSP
connection which is expecting to do key exchange.

From there the server pops the closed connection from the backlog, but
the data_send_bad_key() test case in psp.py hangs waiting to perform
key exchange.

The fix is to properly use _conn_close, which fill force the server to
remove the closed connection from the backlog before sending the RPC
ack to the client.

701b40f8bd declance: Remove IRQF_ONESHOT
Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also disallows force-threading of the primary handler and the
irq-core will warn about this as of commit aef30c8d56 ("genirq: Warn
about using IRQF_ONESHOT without a threaded handler").

The IRQF_ONESHOT flag was added in commit 0fabe1021f ("MIPS:
DECstation I/O ASIC DMA interrupt classes"). It moved
clear_ioasic_dma_irq() from the driver into the irq-chip.
For EOI interrupts the clear_ioasic_dma_irq() callback is now invoked as
->irq_eoi() which is invoked after the IRQ was handled while the
interrupt is masked due to IRQF_ONESHOT. Without IRQF_ONESHOT it would
be invoked while interrupt is unmasked (but interrupts are disabled).

If it is *required* to invoke EOI-ack while the interrupt is masked (and
not a misunderstanding) due to irq-chip cascading/ hierarchical reasons
then using handle_fasteoi_mask_irq() as flow-handler would be the right
way to do so.

Remove IRQF_ONESHOT to irqflags.

629a68865a tcp: move tcp_rack_update_reo_wnd() to tcp_input.c
tcp_rack_update_reo_wnd() is called only once from tcp_ack()

Move it to tcp_input.c so that it can be inlined by the compiler
to save space and cpu cycles.

239f09e258 selftests: ptp: treat unsupported PHC operations as skip
Some PTP hardware clock (PHC) devices may return -EOPNOTSUPP for
operations like settime, adjtime, or adjfreq. This commonly occurs
with timestamp-only PHC implementations that don't support full clock
control.

For background, syzbot previously exposed a crash risk when PTP clock
drivers lacked required callbacks[1]. Subsequent work[2] made callback
presence a registration requirement. As a result, some drivers (like
iwlwifi MVM/MLD[3]) now provide stub callbacks that return -EOPNOTSUPP
for unsupported operations.

When phc_ctl encounters such devices, the "Operation not supported"
error should be treated as a skip (device limitation) rather than a
test failure. This patch:
- Adds [SKIP] output handling in log_test()
- Detects "Operation not supported" from phc_ctl and returns ksft_skip
- Returns ksft_skip if all tests are skipped, preventing false-positive
  results when testing timestamp-only PHC implementations

166e664e70 selftests: ptp: use KSFT_SKIP exit code for skip scenarios
The kselftest framework defines KSFT_SKIP=4 as the standard exit code
for skipped tests. However, phc.sh currently uses a mix of 'exit 0' and
'exit 1' to indicate skip conditions, which can confuse test harnesses
and CI systems.

This patch introduces ksft_skip=4 variable and unifies all skip exit
paths to use 'exit $ksft_skip', consistent with other selftests like
net/lib.sh and net/fib_nexthops.sh.

15e9abc270 net: usb: int51x1: use usbnet_cdc_update_filter
The int51x1 driver uses the same requests as USB CDC to handle packet
filtering, but provides its own definitions and function to handle it.
The chip datasheet says the requests are CDC compliant. Replace this
unnecessary code with a reference to usbnet_cdc_update_filter.

Also fix the broken datasheet link and remove an empty comment.

bbabce5d4d Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue
Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2026-01-26 (ice, idpf)

For ice:
Jake converts ring stats to utilize u64_stats APIs and performs some
cleanups along the way.

Alexander reorganizes layout of Tx and Rx rings for cacheline
locality and utilizes __cacheline_group* macros on the new layouts.

For idpf:
YiFei Zhu adds support for BPF kfunc reporting of hardware Rx timestamps.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  idpf: export RX hardware timestamping information to XDP
  ice: reshuffle and group Rx and Tx queue fields by cachelines
  ice: convert all ring stats to u64_stats_t
  ice: shorten ring stat names and add accessors
  ice: use u64_stats API to access pkts/bytes in dim sample
  ice: remove ice_q_stats struct and use struct_group
  ice: pass pointer to ice_fetch_u64_stats_per_ring
