Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Add the 2.4 GHz RF power offset table for N-PHY rev 8 paired with
radio 2057 rev 8 and wire it to the existing dispatcher.
b43_ntab_get_rf_pwr_offset_table() currently dispatches on phy->rev
== 17 (radio_rev 14) and phy->rev == 16 (radio_rev 9) for 2.4 GHz.
phy->rev == 8 falls through and the function logs:
b43-phyX ERROR: No 2GHz RF power table available for this device
Add a phy->rev == 8 / radio_rev == 8 case returning the new table.
The values are sourced from the proprietary Broadcom wl driver's
nphy_papd_padgain_dlt_2g_2057rev5 array. Reusing the rev 5 values
is structurally appropriate: the IPA TX gain table added by the
preceding patch in this series shares the low 24 bits of every
entry with rev 5 - same gain step amplitudes, only the PAD-gain
selector byte differs. b43's pad_gain extraction in
b43_nphy_tx_pwr_ctl_init() reads bits 19..23 of the gain entry,
which sit in the shared low-24-bit range; the same gain index
therefore maps to the same physical PAD gain code on both
revisions and warrants the same per-index dB offset.
Note that b43_nphy_tx_gain_table_upload() currently has a "TODO:
Enable this once we have gains configured" early-return for
phy->rev >= 7. With that early-return in place, this table is
fetched (silencing the b43err that would otherwise abort PHY
init) but its values are not yet written to MMIO. Resolving the
TODO is a future, separate task.

Add the 2.4 GHz channel info table for N-PHY rev 8 paired with
radio 2057 rev 8 and wire it to the existing dispatcher in
r2057_get_chantabent_rev7().
The dispatcher's case 8 currently handles radio_rev == 5 only.
For radio_rev == 8 both output pointers stay NULL,
b43_nphy_set_channel() returns an error and channel switch to
the default channel fails.
The new b43_nphy_chantab_phy_rev8_radio_rev8[] is 14 entries
covering the standard 2.4 GHz channel set (2412..2472 in 5 MHz
steps, plus 2484 for channel 14).
Values extracted from an MMIO dump of the proprietary Broadcom wl
driver running on BCM6362 silicon (wl driver 6.30.102.7).

Add the 2.4 GHz IPA TX gain table for N-PHY rev 8 paired with radio
2057 rev 8 and wire it to the existing dispatcher.
b43_nphy_get_ipa_gain_table() in tables_nphy.c currently handles
case 8 only for radio_rev == 5; radio_rev == 8 falls through and
the function logs:
b43-phyX ERROR: No 2GHz IPA gain table available for this device
b43-phyX ERROR: PHY init: Channel switch to default failed
leaving b43_phy_init() to return an error and core_init to abort
before the MAC is enabled.
The high byte of every entry differs from the rev 5 sibling (0x40
vs 0x30): different PAD-gain code prefix for the rev 8 front-end.
The low 24 bits coincide with rev 5 across the whole table - the
gain step amplitudes are the same, only the PAD-gain selector
prefix changes.

Add support for radio 2057 revision 8, paired with N-PHY rev 8 on
the Broadcom BCM6362 single-die integrated 2.4 GHz wireless block.
Three correlated changes are needed for the same chip:
- main.c: the radio_rev allow-list under B43_PHYTYPE_N currently
accepts radio 2057 revisions 9 and 14 only; extend to include
rev 8.
- radio_2057.c: the existing r2057_rev8_init[] is a 54-entry stub
declared inside a TODO comment block and never referenced
from r2057_upload_inittabs().
Replace it with the full 412-entry register set actually
programmed by the proprietary Broadcom wl driver on this radio.
I couldn't find the origin of the original 54-entry stub - 8
of its entries do not appear at all in the rev 8 register set
and 7 more carry different values.
Loading it instead of using the real table leaves the radio
hanging producing a "Microcode not responding" timeout.
- radio_2057.c: r2057_upload_inittabs() case 8 handles radio_rev
5 and 7 only; add the radio_rev == 8 branch pointing at the
new table.
The init table is extracted from an MMIO dump of the radio
register set programmed during proprietary driver initialisation
on BCM6362 silicon (Broadcom wl driver 6.30.102.7).

Rev 22 backports the older 802.11 core but pairs it with a radio
in the 2057 family, which requires the 24-bit indirect path. With
the current dispatch, corerev 22 falls into the legacy 4-wire branch,
reads garbage for radio_id, and bails out with -EOPNOTSUPP at the
"FOUND UNSUPPORTED RADIO" branch below.
brcmsmac handles the same silicon family with the equivalent
dispatch in drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/
phy_cmn.c read_radio_reg() and write_radio_reg():
if ((D11REV_GE(pi->sh->corerev, 24)) ||
(D11REV_IS(pi->sh->corerev, 22)
&& (pi->pubpi.phy_type != PHY_TYPE_SSN))) {
/* radioregaddr / radioregdata (indirect) */
} else {
/* phy4waddr / phy4wdatalo (legacy) */
}
b43 does not support SSN/SSLPN PHYs - they are rejected earlier in
b43_phy_versioning() at the "unsupported PHY type" switch - so just
adding the check corerev == 22 will do.

Add d11 core revision 0x16 (= 22) to the b43 bcma device id table.
The b43 bcma id table covers d11 revisions 0x11, 0x15, 0x17, 0x18,
0x1C, 0x1D, 0x1E, 0x28 and 0x2A. Revision 0x16 belongs to the same
N-PHY family as revisions 0x17 and 0x18 (radio 2057) and needs no
new PHY or radio code beyond the radio_rev 8 dispatcher entries
added later in this series - only the device id entry is missing.
Without it bcma scan enumerates the 802.11 core but no driver binds.
The revision is used by the Broadcom BCM6362 single-die integrated
2.4 GHz wireless block found in xDSL SoCs.

... and PCI device helpers.
The various struct pci_device_id arrays were initialized mostly by one
the PCI_DEVICE macros and then list expressions. The latter isn't easily
readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse.
Also use PCI_DEVICE* helper macros to assign .vendor, .device,
.subvendor and .subdevice where appropriate and skip explicit
assignments of 0 (which the compiler takes care of).
The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.
This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

Currently the remain_on_channel operation does not support
filtering incoming frames by destination MAC address. This
prevents use cases such as PASN authentication in the
responder side that need to receive frames addressed to a
specific MAC during the off-channel period.
Add an rx_addr parameter to the remain_on_channel operation
callback and propagate it through the call chain from nl80211
to driver implementations. Introduce the extended feature
NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so
that cfg80211 rejects the request if the driver does not
advertise support for address filtering. Extract the address
from the NL80211_ATTR_MAC attribute when provided in the
netlink message and update the tracing infrastructure to
include the address in remain_on_channel trace events. The
rx_addr parameter is optional and can be NULL, maintaining
backward compatibility with existing drivers.

support most key operations (except setting default data key) on
wdevs instead of netdevs, and adjust all the APIs and tracing to
match.

Currently, a station can only be added to a netdev interface,
mainly because there was no need for a station of a non-netdev
interface.
But for NAN, we will have stations that belong to the NL80211_IFTYPE_NAN
interface.
Prepare for adding/changing/deleting a station that belongs to a non-netdev
interface. This doesn't actually allow such stations - this will be done
in a different patch.

When probe of the sdio brcmfmac device fails for some reasons (i.e.
missing firmware), the sdiodev->bus is set to error instead of NULL, thus
the cleanup later in brcmf_sdio_remove() tries to free resources via
invalid bus pointer. This happens because sdiodev->bus is set 2 times:
first in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix
this by chaning the brcmf_sdio_probe() function to return the error code
and set sdio->bus only there.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.
As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Currently, whenever there is a need to transmit an Action frame,
the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to
firmware. The P2P interfaces were available when wpa_supplicant is managing
the wlan interface.
However, the P2P interfaces are not created/initialized when only hostapd
is managing the wlan interface. And if hostapd receives an ANQP Query REQ
Action frame even from an un-associated STA, the brcmfmac driver tries
to use an uninitialized P2P vif pointer for sending the IOVAR to firmware.
This NULL pointer dereferencing triggers a driver crash.

Fix this, by always using the vif corresponding to the wdev on which the
Action frame Transmission request was initiated by the userspace. This way,
even if P2P vif is not available, the IOVAR is sent to firmware on AP vif
and the ANQP Query RESP Action frame is transmitted without crashing the
driver.
Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev()
to brcmf_p2p_attach(). Because the former function would not get executed
when only hostapd is managing wlan interface, and it is not safe to do
reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior
init_completion().
And in the brcmf_p2p_tx_action_frame() function, the condition check for
P2P Presence response frame is not needed, since the wpa_supplicant is
properly sending the P2P Presense Response frame on the P2P-GO vif instead
of the P2P-Device vif.

hostapd & wpa_supplicant userspace daemons exposes an AP mode specific
config file parameter "ap_isolate" to the user, which is used to control
low-level bridging of frames between the stations associated in the BSS.
In driver, handle this user setting in the newly defined cfg80211_ops
function brcmf_cfg80211_change_bss() by enabling "ap_isolate" IOVAR in
the firmware.
In AP mode, the "ap_isolate" value from the cfg80211 layer represents,
0 = allow low-level bridging of frames between associated stations
1 = restrict low-level bridging of frames to isolate associated stations
-1 = do not change existing setting

The NVRAM selection logic in brcmf_fw_request_nvram_done() used
patterns like:
if ((data = bcm47xx_nvram_get_contents(&data_len)))
free_bcm47xx_nvram = true;
else if ((data = brcmf_fw_nvram_from_efi(&data_len)))
kfree_nvram = true;
This style violates kernel coding style guidelines and triggers
checkpatch.pl errors. It also slightly reduces readability.
Refactor these cases by separating the assignment and the check,
ensuring behavior remains identical while complying with coding
standards.

The brcmf_btcoex_detach() only shuts down the btcoex timer, if the
flag timer_on is false. However, the brcmf_btcoex_timerfunc(), which
runs as timer handler, sets timer_on to false. This creates critical
race conditions:
1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()
is executing, it may observe timer_on as false and skip the call to
timer_shutdown_sync().
2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_info
worker after the cancel_work_sync() has been executed, resulting in
use-after-free bugs.
The use-after-free bugs occur in two distinct scenarios, depending on
the timing of when the brcmf_btcoex_info struct is freed relative to
the execution of its worker thread.
Scenario 1: Freed before the worker is scheduled
The brcmf_btcoex_info is deallocated before the worker is scheduled.
A race condition can occur when schedule_work(&bt_local->work) is
called after the target memory has been freed. The sequence of events
is detailed below:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... |
kfree(cfg->btcoex); // FREE |
| schedule_work(&bt_local->work); // USE
Scenario 2: Freed after the worker is scheduled
The brcmf_btcoex_info is freed after the worker has been scheduled
but before or during its execution. In this case, statements within
the brcmf_btcoex_handler() — such as the container_of macro and
subsequent dereferences of the brcmf_btcoex_info object will cause
a use-after-free access. The following timeline illustrates this
scenario:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... | schedule_work(); // Reschedule
|
kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker
/* | btci = container_of(....); // USE
The kfree() above could | ...

To resolve the race conditions, drop the conditional check and call
timer_shutdown_sync() directly. It can deactivate the timer reliably,
regardless of its current state. Once stopped, the timer_on state is
then set to false.

For WPA3-SAE Connection in EXTSAE mode, the userspace daemon is allowed to
generate the SAE Auth frames. The driver uses the "mgmt_frame" FW IOVAR to
transmit this MGMT frame.
Before sending the IOVAR, the Driver is incorrectly treating the channel
number read from the FW as a frequency value and again attempts to convert
this into a channel number using ieee80211_frequency_to_channel().
This added an invalid channel number as part of the IOVAR request to the FW
And some FW which strictly expects a valid channel would return BAD_CHAN
error, while failing to transmit the driver requested SAE Auth MGMT frame.
Fix this in the CYW vendor specific MGMT TX cfg80211 ops handler, by not
treating the channel number read from the FW as frequency value and skip
the attempt to convert it again into a channel number.
Also fix this in the generic MGMT TX cfg80211 ops handler.
