When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via mdiobus, there is no verification of
parameters passed to the ioctl and it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation.

This reverts commit 4fcfcbe45734 ("wifi: mwifiex: Fix HT40 bandwidth
issue.")
That commit introduces a regression, when HT40 mode is enabled,
received packets are lost, this was experience with W8997 with both
SDIO-UART and SDIO-SDIO variants. From an initial investigation the
issue solves on its own after some time, but it's not clear what is
the reason. Given that this was just a performance optimization, let's
revert it till we have a better understanding of the issue and a proper
fix.

According to 802.1AE standard, when ES and SC flags in TCI are zero,
used SCI should be the current active SC_RX. Current code uses the
header MAC address. Without this patch, when ES flag is 0 (using a
bridge or switch), header MAC will not fit the SCI and MACSec frames
will be discarted.
In order to test this issue, MACsec link should be stablished between
two interfaces, setting SC and ES flags to zero and a port identifier
different than one. For example, using ip macsec tools:
ip link add link $ETH0 macsec0 type macsec port 11 send_sci off
end_station off
ip macsec add macsec0 tx sa 0 pn 2 on key 01 $ETH1_KEY
ip macsec add macsec0 rx port 11 address $ETH1_MAC
ip macsec add macsec0 rx port 11 address $ETH1_MAC sa 0 pn 2 on key 02
ip link set dev macsec0 up
ip link add link $ETH1 macsec1 type macsec port 11 send_sci off
end_station off
ip macsec add macsec1 tx sa 0 pn 2 on key 01 $ETH0_KEY
ip macsec add macsec1 rx port 11 address $ETH0_MAC
ip macsec add macsec1 rx port 11 address $ETH0_MAC sa 0 pn 2 on key 02
ip link set dev macsec1 up

Enable memory-mapped I/O access to RMON statistics registers for devices
known to work correctly. Currently, only the D-Link DGE-550T (`0x4000`)
with PCI revision A3 (`0x0c`) is allowed.
To avoid issues on other hardware, a runtime check was added to restrict
MMIO usage. The `MEM_MAPPING` macro was removed in favor of runtime
detection.
To access RMON registers, the code `dw32(RmonStatMask, 0x0007ffff);`
must also be skipped, so this patch conditionally disables it as well.

Before appending sysdata, prepare_extradata() checks if any feature is
enabled in sysdata_fields (and exits early if none is enabled).
When SYSDATA_RELEASE was introduced, we missed adding it to the list of
features being checked against sysdata_fields in prepare_extradata().
The result was that, if only SYSDATA_RELEASE is enabled in
sysdata_fields, we incorreclty exit early and fail to append the
release.
Instead of checking specific bits in sysdata_fields, check if
sysdata_fields has ALL bit zeroed and exit early if true. This fixes
case when only SYSDATA_RELEASE enabled and makes the code more general /
less error prone in future feature implementation.

Intel Wired LAN Driver Updates 2025-06-09 (ice, i40e, ixgbe, iavf)
Jake moves from individual virtchnl RSS configuration values, for ice,
i40e, and iavf, to a common libie location and values.
Martyna and Dawid add counters for link_down_events to ice, i40e, and
ixgbe drivers. The counter increments only on actual physical link-down
events visible to the PHY. It does not increment when the user performs
a software-only interface down/up (e.g. ip link set dev down).
The counter does increment in cases where the interface is reinitialized
in a way that causes a real link drop - such as eg. when attaching
an XDP program, reconfiguring channels, or toggling certain priv-flags.
For ice:
Arkadiusz and Karol separate PTP and DPLL functionality to their

Add unregister_netcons_consoles() function to automatically unregister
console handlers when no targets of the corresponding type remain active.
The function iterates through the target list to determine which console
types (basic vs extended) are still needed, and unregisters any console
handlers that are no longer required. This prevents having registered
console handlers without corresponding active targets.
The function is called when a target is disabled and moved to the cleanup
list, ensuring proper cleanup of unused console registrations.

The netconsole driver currently registers the basic console driver
unconditionally during initialization, even when only extended targets
are configured. This results in unnecessary console registration and
performance overhead, as the write_msg() callback is invoked for every
log message only to return early when no matching targets are found.
Optimize the driver by conditionally registering console drivers based
on the actual target configuration. The basic console driver is now
registered only when non-extended targets exist, same as the extended
console. The implementation also handles dynamic target creation through
the configfs interface.
This change eliminates unnecessary console driver registrations,
redundant write_msg() callbacks for unused console types, and associated
lock contention and target list iterations. The optimization is
particularly beneficial for systems using only the most common extended
console type.

Previously, e1000_down called cancel_work_sync for the e1000 reset task
(via e1000_down_and_stop), which takes RTNL.
As reported by users and syzbot, a deadlock is possible in the following
scenario:
CPU 0:
- RTNL is held
- e1000_close
- e1000_down
- cancel_work_sync (cancel / wait for e1000_reset_task())
CPU 1:
- process_one_work
- e1000_reset_task
- take RTNL
To remedy this, avoid calling cancel_work_sync from e1000_down
(e1000_reset_task does nothing if the device is down anyway). Instead,
call cancel_work_sync for e1000_reset_task when the device is being
removed.

When a VFLR interrupt is received during a VF reset initiated from a
different source, the VFLR may be not fully handled. This can
leave the VF in an undefined state.
To address this, set the I40E_VFLR_EVENT_PENDING bit again during VFLR

VF reset request, using the return value of i40e_reset_vf as an indicator
of whether the reset was successfully triggered. Currently, i40e_reset_vf
always returns true, which causes new reset requests to be ignored if a
different VF reset is already in progress.
This patch updates the return value of i40e_reset_vf to reflect when
another VF reset is in progress, allowing the caller to properly use
the retry mechanism.

commit cfd98c838cbe ("can: netlink: move '=' operators back to

between the IFLA_CAN_DATA_BITTIMING_CONST array index and the equal
sign.
Remove it.

The RTW_WCPU_11AC and RTW_WCPU_11N enums are used to identify two
types of microcontrollers used in Realtek chips, but these names are
misleading. The "11AC" type was also used in 11n devices (e.g.
RTL8733BU, not supported by rtw88), and the "11N" type was also used
in 11ac devices (RTL8821AU, RTL8812AU).
Rename RTW_WCPU_11AC to RTW_WCPU_3081 and RTW_WCPU_11N to RTW_WCPU_8051.
(8051 is well known. It's less clear what 3081 is, but the out of tree
drivers use this name.)

The RF 0x18 register stores radio frequency domain parameters, including

role status. Since rtw89 doesn't use the status yet, add a dummy handler

Append a new field for RFE (RF Front End) type to RF TSSI H2C command.
FW has forward compatibility when handling this H2C command, so just
need to consider backward cases in FW point of view.

old driver | O | X

new driver | O | O
Currently only RTL8922A uses this RF TSSI H2C command. Increase its FW
format max and will let new FW binary align with it. Then, old driver
won't load new FW.

To support channel switch on STA mode, declare IEEE80211_HW_CHANCTX_STA_CSA
and implement ieee80211_ops::switch_vif_chanctx. Handling of CSA procedure
still relies on mac80211 SW flow, since FW doesn't support chanctx offload.

Previously, default chandef is configured if no chanctx is active, i.e. no
chanctx is assigned to some vif. For normal cases, it's fine. However, for
impending CSA support, need to consider that one chanctx may be added, or
called registered, ahead without being assigned immediately. Then, it will
keep inactive, and might be covered by the default one when re-calculating
chanctxs happens in certain sequences. So now, don't re-config the default
chandef unless no chanctx is registered.

rtw89_sar_set_src() may be called at driver early init phase when
applying SAR configuration via ACPI. wiphy lock is not held there.
Since the assertion was initially added for rtw89_apply_sar_common() call
path and may be helpful for other places in future changes, keep it but
move it under RTW89_FLAG_PROBE_DONE test.
