Add helper functions for creating and destroying PSP steering objects to
reduce code duplication.
This will become more relevant in future patches which add more steering
tables/groups/flows.
One nice side-effect of this is that the cleanup functions become
idempotent and can be used instead of long goto chains. This further
simplifies the code.

The rx_err table is different than the others, having separate functions
to create the flow rules in addition to the flow table.
Merge the add/delete rules functions with the ft create/delete functions
for consistency.

PSP steering uses reference counting for TX and RX steering tables, but
there's only a single reference for each acquired and thus the reference
counting is unnecessary.
Remove it and consolidate functions to simplify the code.

PSP steering uses three mutexes to serialize steering rule init/cleanup.
But init/cleanup are already serialized with the higher level devlink
lock (for both device init and esw mode changes), so there's no need for
multiple additional mutexes.
Remove them to make room for the new changes.
Later in the series, the netdev lock will be used to serialize PSP
steering changes from multiple sources, so don't bother adding
assertions now only for them to be overwritten later.

The legacy firmware update path does not support per-component updates.
If a user specifies a component parameter with devlink flash, reject
the request with -EOPNOTSUPP rather than silently ignoring the component

hwsim_tx_info_frame_received_nl() casts the HWSIM_ATTR_TX_INFO payload
to a struct hwsim_tx_rate * and unconditionally reads
IEEE80211_TX_MAX_RATES entries (8 bytes) from it. The policy only bounds
the attribute from above (NLA_BINARY .len is a maximum) and the op sets
GENL_DONT_VALIDATE_STRICT, so a short or zero-length attribute is
accepted and the loop reads past the payload.
Require the exact length in the policy, so a malformed attribute is
rejected before the handler runs.

brcmf_fw_crashed() and the debugfs "reset" entry both schedule
drvr->bus_reset, whose callback recovers drvr through container_of()
and dereferences it. The removal path frees drvr (brcmf_free ->
wiphy_free) without draining the work, so a bus_reset callback pending
or running during removal can outlive drvr.
Cancellation cannot live in brcmf_detach() or brcmf_free(): the work
callback reaches teardown through the bus .reset op (PCIe
brcmf_pcie_reset -> brcmf_detach; SDIO brcmf_sdio_bus_reset ->
brcmf_sdiod_remove -> brcmf_free), so cancelling there would wait for
the running work and deadlock.
Add a per-bus mutex (bus_reset_lock) and route all arming through
brcmf_bus_schedule_reset(), which under the lock skips when the bus is
marked removing. Each bus remove entry calls
brcmf_bus_cancel_reset_work(), which under the same lock sets removing
and cancels the work. Holding the mutex across cancel_work_sync() makes
the set-removing + drain step atomic. Every producer reaches the arming
path from process context -- the PCIe firmware-halt notification runs in
the threaded IRQ handler (brcmf_pcie_isr_thread) and the SDIO hostmail
path runs from the data workqueue -- so the mutex is taken only in
sleepable contexts. Where applicable the remove entry first stops the
firmware-crash producer: on PCIe mask the mailbox and synchronize_irq;
on SDIO unregister the bus interrupt and cancel the data worker, which
also reports firmware halts through brcmf_fw_crashed(). The mutex is
initialized at bus allocation. The SDIO suspend power-off path frees
drvr through the same brcmf_sdiod_remove() and takes the same lock;
resume re-allows the work only on a successful re-probe.
Also guard brcmf_fw_crashed() against a NULL bus_if/drvr: it can fire
before brcmf_attach() wires up drvr, and it dereferences drvr
(bphy_err/brcmf_dev_coredump) before reaching the arming gate.
The bus_reset work is shared across buses, so the drain is applied to
every remove path: PCIe (the .reset op introduced by the Fixes commit),
SDIO (arms the same work through brcmf_fw_crashed()), and USB (via the
debugfs "reset" entry). cancel_work_sync() drains a running or pending
bus_reset work item before removal frees drvr, and patch 1/2 makes the
scratch-buffer release safe when reset teardown has already released
those DMA buffers.
This patch fixes the lifetime of the bus_reset work item itself. It does
not attempt to address the separate, pre-existing lifetime of the
asynchronous firmware completion started by the PCIe reset path. That
callback needs its own lifetime/ownership protocol and is being tracked
separately.

brcmf_pcie_release_scratchbuffers() frees the shared.scratch and
shared.ringupd DMA buffers with dma_free_coherent() but does not clear
the pointers afterwards, unlike the sibling release_ringbuffers() which
NULLs commonrings/flowrings/idxbuf on release.
Both the bus_reset .reset callback (brcmf_pcie_reset) and
brcmf_pcie_remove() call release_scratchbuffers. When reset teardown
has run before removal, remove's own teardown would call
dma_free_coherent() a second time on the already-freed DMA allocation.
NULL the pointers after free, matching release_ringbuffers(), so a later
release observes that the allocation has already been released. This
patch makes repeated sequential release safe; the reset-work lifetime is
handled separately by the following patch.

mwifiex_tdls_add_ht_oper() gates its follow-the-AP-bandwidth path on
bss_desc->bcn_ht_cap being present, but then dereferences a different
pointer, bss_desc->bcn_ht_oper:

bss_desc->bcn_ht_cap &&
ISALLOWED_CHANWIDTH40(bss_desc->bcn_ht_oper->ht_param))
bcn_ht_cap and bcn_ht_oper are populated independently while parsing the
associated AP's beacon in mwifiex_update_bss_desc_with_ie(): an AP that
advertises an HT Capabilities element but no HT Operation element leaves
bcn_ht_cap non-NULL and bcn_ht_oper NULL. Setting up a TDLS link to a
peer while associated to such an AP then dereferences the NULL
bcn_ht_oper and crashes the kernel. Every other bcn_ht_oper user in the
driver NULL-checks it first.
Guard on the pointer that is actually dereferenced.

at76_guess_freq() checks only that the received frame is at least a bare
802.11 header (24 bytes) before subtracting the fixed management-body
offset:
len -= el_off;
For both beacon and probe response frames, el_off is 36. If the frame is
shorter than el_off, subtracting it causes the calculated IE length to
wrap. The length is eventually passed to cfg80211_find_elem_match() as a
very large unsigned value, so the element walk runs beyond the RX skb.
This path is reached from at76_rx_tasklet() while scanning. If the device
delivers a truncated beacon or probe response, the oversized IE length
causes an out-of-bounds read during scanning.
Skip the IE lookup if the frame does not reach the variable elements,
before subtracting el_off.

mwifiex_process_uap_event() handles EVENT_UAP_STA_ASSOC by exposing the
(re)association request IEs that the firmware copies into the event:
sinfo->assoc_req_ies = &event->data[len];
len = (u8 *)sinfo->assoc_req_ies - (u8 *)&event->frame_control;
sinfo->assoc_req_ies_len = le16_to_cpu(event->len) - (u16)len;
event->len is supplied by the device firmware and is never validated,
and the subtraction is unchecked. assoc_req_ies points into
adapter->event_body[MAX_EVENT_SIZE], a fixed-size array embedded in the
kmalloc()'d struct mwifiex_adapter.
On the ap_11n_enabled path mwifiex_set_sta_ht_cap() walks these IEs with
cfg80211_find_ie(), whose for_each_element() loop dereferences each
element header. A firmware-reported event->len larger than the bytes
actually received makes assoc_req_ies_len describe IEs that extend past
event_body, so the walk reads out of the adapter slab object, a
slab-out-of-bounds read (KASAN: slab-out-of-bounds in cfg80211_find_ie).
An event->len smaller than the header instead makes the int subtraction
negative, which wraps to a huge size_t when stored in assoc_req_ies_len.
The same length is handed to cfg80211_new_sta(), so a more modest
over-claim can also copy stale event_body bytes into the
NL80211_CMD_NEW_STATION notification.
A malicious or malfunctioning mwifiex device (USB/SDIO/PCIe) can deliver
such an event while the interface is in AP/uAP mode.
Validate event->len before use: reject a length that underflows the
header or that would place the IEs outside the event_body[] buffer the
event was copied into. event->len here is struct mwifiex_assoc_event.len,
a payload field internal to this event, not the transport frame length,
so it is validated in this handler rather than at the generic
MWIFIEX_TYPE_EVENT receive path, which only sees the event cause and the
transport frame length. The bound is against event_body[MAX_EVENT_SIZE]
rather than the actually-received length because the transports store the
event differently (USB and SDIO leave the 4-byte event header in
event_skb, PCIe strips it via skb_pull), whereas event_body is the single
fixed buffer all of them copy the event into. This is the event-path
analogue of the receive-path bounds checks added in commit 119585281617
("wifi: mwifiex: Fix OOB and integer underflow when rx packets").

wilc_parse_assoc_resp_info() computes the trailing IE length as
ies_len = buffer_len - sizeof(*res);
without first checking that buffer_len is at least sizeof(struct
wilc_assoc_resp) (6 bytes). buffer_len is the length reported for a
received association response (host_int_parse_assoc_resp_info() passes
hif_drv->assoc_resp / assoc_resp_info_len straight in) and must be
validated before the driver accesses the fixed header.
For a frame shorter than the 6-byte fixed header, the subtraction wraps.
For a four-byte response the result is truncated to a u16 ies_len of
65534, so kmemdup() then attempts to copy 65534 bytes starting at
buffer + sizeof(*res), beyond the valid association-response data
(CWE-125). A response shorter than four bytes can also cause an
out-of-bounds read of res->status_code at offsets 2 and 3.
Reject frames too short to hold the fixed header before touching the
header or computing ies_len. Also set the connection status to a failure
on this path: the caller falls through to a
"conn_info->status == WLAN_STATUS_SUCCESS" check after the parser
returns, so leaving the status untouched could let a malformed short
response be treated as a successful association.

Fix regression in rgpower table loading, caused by using
request_firmware(): when the requested firmware does not exist, e.g.
nxp/rgpower_WW.bin does not exist on OpenWRT builds for WRT3200ACM,
request_firmware() falls back to firmware_fallback_sysfs(), which expects
the firmware to be provided by user space using SYSFS. No such utility is
provided in this configuration, so the entire system locks up for 60
seconds, until the request times out. During this time, no other log
messages are observed, and the device does not respond to commands over
UART.
The request_firmware() call is performed in the following context:
current->comm kworker/1:2 in_task 1 irqs_disabled 0 in_atomic 0
Fixed by using request_firmware_direct(). This prevents fallback to SYSFS,
and avoids delay. The rgpower table is optional. The driver falls back
to the device tree power table if the firmware is not present.
The error code is printed for debugging and returned to the caller,
which only cares for success or failure, so there are no side effects.

wanxl_pci_init_one() stores the freshly allocated card in driver data
before the PLX BAR is mapped. Several early probe failures then unwind
through wanxl_pci_remove_one(), including failure to allocate the coherent
status area or to restore the DMA mask.
wanxl_pci_remove_one() unconditionally calls wanxl_reset(), and
wanxl_reset() dereferences card->plx. On those early failures card->plx
is still NULL, so the error path can dereference a NULL MMIO pointer.
Only issue the hardware reset once the BAR mapping exists. The remaining
cleanup in wanxl_pci_remove_one() already checks whether later resources
were allocated.

immediately passes that handle to nfp_cpp_mutex_trylock().
However, nfp_cpp_mutex_alloc() returns NULL on failure. If that happens
for a matching table entry, the resource lookup still returns success and
the following trylock dereferences a NULL mutex pointer while opening the
resource.
nfp_resource_acquire() already treats failure to allocate the table mutex
as -ENOMEM. Do the same for the resource mutex and fail the lookup before

A subsequent patch is going to make the driver ops-locked and allow
ethtool operations to run without RTNL. In preparation for this change,
tell the core about a couple of ethtool operations that should remain
under RTNL:
1. Set pause parameters: Configures the port's headroom buffer which is
also configured by RTNL-only paths such as DCB and qdisc. These paths
can probably be converted to acquire the netdev instance lock, but this
operation in not frequently called (unlike stats query), so avoid the
added complexity for now.
2. Get link state: Calls ethtool_op_get_link() which requires RTNL. See
commit 1105ef941c1a ("net: ethtool: keep rtnl_lock for ops using
ethtool_op_get_link()").
All the other operations do not access shared resources, do not invoke
helpers that require RTNL or already have the appropriate locking in
place.

airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE,
but some callers expect the NPU to write response data back into the
same buffer:
- airoha_npu_wlan_msg_get() (NPU_OP_GET): NPU writes response into
the buffer, then the caller reads it via memcpy()
- airoha_npu_ppe_stats_setup() (NPU_OP_SET): NPU writes back
npu_stats_addr field in the response
On non-cache-coherent architectures like EN7581 (Cortex-A53 without
hardware cache coherency for NPU DMA), DMA_TO_DEVICE unmap is a no-op
— it does not invalidate the CPU cache. If the NPU-written cache line
is still present in the CPU cache when the caller reads the buffer,
the CPU observes stale data instead of the NPU response.
This is a timing-sensitive bug: small mailbox buffers (~24 bytes)
typically fit in a single cache line and may survive in the cache
until the caller reads them, producing silent data corruption rather
than a crash. The bug is more likely to trigger when the caller reads
the response immediately after dma_unmap_single() without intervening
cache-evicting operations.
Fix by using DMA_BIDIRECTIONAL for both map and unmap, which ensures
dma_unmap_single() invalidates the CPU cache on non-coherent systems.
The mailbox buffers are small so there is no performance concern.

Drop the endpoint device reference after closing the MAC and before

airoha_ppe_deinit() replaces the NPU pointer with NULL via
rcu_replace_pointer() but does not wait for existing RCU readers
to exit before calling ppe_deinit() and airoha_npu_put(). This can
cause a use-after-free if a reader in an RCU read-side critical
section still holds a reference to the NPU when it is freed.
The init path (airoha_ppe_init) already calls synchronize_rcu()
after rcu_assign_pointer(), but the deinit path introduced in
commit 6abcf751bc08 ("net: airoha: Fix schedule while atomic in
airoha_ppe_deinit()") omitted the matching barrier when switching
from rcu_read_lock()/rcu_dereference() to rcu_replace_pointer().
Add synchronize_rcu() before ppe_deinit() to ensure all existing
RCU readers have completed before the NPU resources are released.

GTPv1-U packets may carry a chain of extension headers before the inner
IP packet. The receive path already parses and skips these extension
headers, but it currently reads the inner protocol before doing so.
As a result, the first extension header byte is interpreted as the inner
IP version. Packets with extension headers are then dropped before PDP
lookup.
Parse the extension header chain before calling gtp_inner_proto(), so the
inner protocol is read from the actual inner IP header.

Add a driver for ADIN1140. The device is a 10BASE-T1S MAC-PHY
(integrated in the same package) that connects to a CPU over an SPI bus,
and implements the Open Alliance TC6 protocol for control and frame
transfers. As such, this driver relies on oa_tc6 for the communication
with the device. The device has an alternative name (AD3306), so the
driver can be probed using one of the two compatible strings.
For control transactions, ADIN1140 only implements the protected mode.
The driver has a custom implementation for the mii_bus access methods as a
workaround for hardware issues:
1. The OA TC6 standard defines the direct and indirect access modes for
MDIO transactions. The ADIN1140 incorrectly advertises indirect mode
only (supported capabilities register - 0x2, bit 9), while actually
implementing just the direct mode. We cannot rely on the CAP register
to choose an access method (which oa_tc6 does by default, even though
it only implements the direct mode), so the driver has to use its
own.
2. The ADIN1140 cannot access the C22 register space of the internal
PHY, while the PHY is busy receiving frames. If that happens, the
CONFIG0 and CONFIG2 registers of the MAC will get corrupted and the
data transfer will stop. Those two registers configure settings for
the transfer protocol between the MAC and host, so the value for some
of their subfields shouldn't be changed while the netdev is up.
Since we know the PHY is internal, the MAC driver can implement a
custom mii_bus, which can intercept C22 accesses. Most of the
registers mapped in the 0x0 - 0x3 range (the only ones the PHY offers)
are read only, and their value can be read from somewhere else (e.g
the PHYID 1 & 2 have the same value as 0x1 in the MAC memory map).
For the fields that are R/W (loopback and AN/reset) in the control
register, the PHY driver already implements the set_loopback() and
config_aneg() functions. The C22 write function of the driver is a
no-op and is used to protect against the ioctl MDIO access path.
C45 accesses do not cause this issue, so we can properly implement
them.

being up.
The device implements both C22 and C45 MDIO access methods, but can only
be discovered over C22, since the C45 MMD devices lack the MDIO_DEVID1 and

Implement the OA TC6 standard defined protected mode for control (register
access) transactions. In addition to the current register access formats
the oa_tc6 driver handles, 1's complement values of the data field
are included (by both the host and the MACPHY) in the SPI transfer frames.
This feature acts as an integrity check.
Control write transactions look like this:
|<- 32 bits ->|<--- data_size --->|<- 32 bits ->|
MOSI: | ctrl header | reg write data | ignored |
MISO: | (discard) | echoed ctrl hdr | echoed data |
data_size (LEN = number of registers to read in a sequence):
Unprotected: 32 x (LEN + 1) bits
Protected: 2 x 32 x (LEN + 1) bits
Control read transaction:
|<- 32 bits ->|<--- 32 bits --> |<- data_size ->|
MOSI: | ctrl header | ignored ... |
MISO: | (discard) | echoed ctrl hdr | reg read data |
data_size (LEN = number of registers to read in a sequence):
Unprotected: 32 x (LEN + 1) bits
Protected: 2 x 32 x (LEN + 1) bits
Register data format ("reg write data" and "reg read data"):
Unprotected:
| W1 (normal) | W2 (normal) | ... | Wx (normal) |
Protected:
| W1 (normal) | W1 (complement) | ... | Wx (normal) | Wx (complement)|
The protected mode state can be read from the bit 5 of CONFIG0 (0x4)
register, and this setting is usually only configured during the
MACPHY's reset (depending on the device it can be done by setting the
state of a pin). We can read the protected mode configuration before any
other register access and since the SPI transfer is initially sized for an
unprotected read, the MACPHY's complement words are never clocked out
and no checking is required. The data transactions (Ethernet frames)
remain unchanged.

On the TSN and RED variants of LAN969x and SparX-5i TAS (Time-Aware Shaper)
is present in the silicon.
Currently, the driver does not use configure it at all, which means that
the TAS_PROFILE_CONFIG.LINK_SPEED[1] value is left at the default of 3
which means that its configured for 1 Gbps.
So, running iperf between two 10G switch ports will result in only 940-ish
Mbps while we should be getting around 9.3 Gbps.
Correctly populating the TAS_PROFILE_CONFIG.LINK_SPEED[1] with the current
port speed fixes this issue and we achieve around 9.4 Gbps between two 10G
switch ports.
So, port the TAS port link speed setting from the vendor BSP 6.18 kernel[2]

REG_FE_GDM_MIB_CLEAR after every read creates a race window where
packets arriving between read and clear are lost from statistics.
Switch to a delta-based approach instead:
- 64-bit H+L registers (ok pkts/bytes, E64..L1023): read absolute
hardware total directly into a local variable; clamp with max(new, old)
to prevent torn-read regression when the counter carries between the
two reads.
- 32-bit registers (drops, bc, mc, errors, runt, long): accumulate
(u32)(curr - prev) into a 64-bit software counter; unsigned
subtraction handles wrap-around transparently.
- tx/rx_len[0] ([0,64] bucket): combines RUNT_CNT (32-bit, delta via
tx_runt/rx_runt) and E64_CNT (64-bit, absolute) into a single local
accumulator; max(new, old) applied here too to guard against a torn
read of E64 when the RUNT accumulator is unchanged between polls.
MIB counters are zeroed by the SCU FE reset (EN7581_FE_RST) asserted
in airoha_hw_init() at module load, so no explicit MIB clear is needed
in airoha_fe_init().
Merge airoha_dev_get_hw_stats() into airoha_update_hw_stats() and
move stats_lock inside. Plain spin_lock() is correct: the function
is only called from ndo_get_stats64() in process context. Each dev
refreshes only its own MIB counters; sibling devs on a shared GDM3/4
port are polled when their own netdev is queried.

Convert geneve->cfg to an RCU-protected pointer, allowing lockless

- geneve_configure() allocates config and publishes it via RCU.
- Setting dev->priv_destructor = geneve_free_dev handles config cleanup
if register_netdevice() fails or during netdev unregistration.
- geneve_changelink() performs RCU swap; old config is freed via call_rcu_hurry().
- Allocates new dst_cache during changelink to prevent pcpu sharing.
- Removed geneve_quiesce/unquiesce() and synchronize_net() from changelink.

The eth1 MAC exhibits silicon-inherent RX and TX timing behavior that
differs from the eth0 implementation.
At 1000Mbps, RX sampling requires clock inversion due to a fixed MAC
input skew that cannot be compensated by standard RGMII delay settings.
The TX path includes a fixed ~2ns internal delay introduced by the MAC
silicon. This delay is always present and is already accounted for in
the device tree tx-internal-delay-ps property as part of the effective
output timing.
The tx-internal-delay-ps property describes the effective delay seen at
the MAC output. Since the hardware register controls only the
programmable portion of the delay, the driver subtracts the fixed
silicon-inherent component before programming the delay register.
Use compatible-specific match data to identify the eth1 variant and
apply RX clock inversion only at 1000Mbps.
The PHY interface mode is adjusted via phy_fix_phy_mode_for_mac_delays()
to avoid double-application of RGMII delays when MAC-side delays are
already present.
Link speed dependency means RX sampling configuration is applied in the
fix_mac_speed callback after negotiation.
No behavior changes for the existing eth0 controller.

Make rx-internal-delay-ps and tx-internal-delay-ps optional in the
EIC7700 DWMAC driver.
The driver previously required both properties to be present and would
fail probe when they were missing. This restricts valid hardware
configurations where RGMII timing is instead provided by the PHY or
board design.
Update the driver to treat missing delay properties as zero delay,
allowing systems without explicit MAC-side delay tuning to operate
correctly.
This aligns the driver behavior with the updated device tree binding
and provides a safe default configuration when MAC-side delay
programming is not required.
