The 4329 throughput drops from 40.2 Mbits/sec to 190 Kbits/sec in 2G
11n mode because the commit b41c232d33 ("brcmfmac: reserve 2 credits
for host tx control path"). To fix the issue, host driver only reserves
tx control credit when there is a txctl frame is pending to send. And
we also check available credit by using "not equal to 0" instead of
"greater than 0" because tx_max and tx_seq are circled positive numbers.

(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.
Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

The driver relies on the compatible string from DT to determine which
FW configuration file it should load. The DTS spec allows for '/' as
part of the compatible string. We change this to '-' so that we will
still be able to load the config file, even when the compatible has a
'/'. This fixes explicitly the firmware loading for
"solidrun,cubox-i/q".

When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.

It is observed that sometimes when sdiod is low in tx credits in low
rssi scenarios, the data path consumes all sdiod rx all credits and
there is no sdiod rx credit available for control path causing host
and card to go out of sync resulting in link loss between host and
card. So in order to prevent it some credits are reserved for control
path.
Note that TXCTL_CREDITS can't be larger than the firmware default
credit update threshold 2; otherwise there will be a deadlock for both

Since the driver was first introduced into the kernel, it has only
handled the ciphers associated with WEP, WPA, and WPA2. It fails with
WPA3 even though mac80211 can handle those additional ciphers in software,
b43legacy did not report that it could handle them. By setting MFP_CAPABLE using
ieee80211_set_hw(), the problem is fixed.
With this change, b43legacy will handle the ciphers it knows in hardware,
and let mac80211 handle the others in software. It is not necessary to
use the module parameter NOHWCRYPT to turn hardware encryption off.
Although this change essentially eliminates that module parameter,
I am choosing to keep it for cases where the hardware is broken,
and software encryption is required for all ciphers.

all Cypress macro names as they belong to SDIO Broadcom vendor ID.
Change also Cypress 43012 value from decimal do hexadecimal notation to be
consistent with all other values.

An incorrect value of use_fwsup is set for 4-way handshake offload for
WPA//WPA2-PSK, caused by commit 3b1e0a7bdf ("brcmfmac: add support for
SAE authentication offload"). It results in missing bit
BRCMF_VIF_STATUS_EAP_SUCCESS set in brcmf_is_linkup() and causes the
failure. This patch correct the value for the case.
Also setting bit BRCMF_VIF_STATUS_EAP_SUCCESS for SAE offload case in
brcmf_is_linkup() to fix SAE offload failure.

The driver sends an action frame down and waits for dwell time to be
completed or aborted before sending out the next action frame.
Driver issues "scan abort" to cancel the current time slot, but this
doesn't have any effect because, we are not using scan engine for
sending action frame.
Fix is to use "actframe_abort" to cancels the current action frame.

In WLAN, priority among various access categories of traffic is
always set by the AP using WMM parameters and this may not always
follow the standard 802.1d priority.
In this change, priority is adjusted based on the AP WMM params
received as part of the Assoc Response and the same is later used
to map the priority of all incoming traffic.
In a specific scenario where EDCA parameters are configured to be same
for all ACs, use the default FW priority definition to avoid queuing
packets of all ACs to the same priority queue.

* 11n - 5.2.31 ACM Bit Conformance test

When calling debugfs functions, there is no need to ever check the

never do something different based on this.
In doing this, make brcmf_debugfs_add_entry() return void as no one was
even paying attention to the return value.

The firmware does not respond ARP request and causes ping failure with
following steps:
1. Bring up interface
ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
ifconfig wlan0 192.168.100.10
3. Bring down interface or
ifconfig wlan0 down or kill wpa_supplicant
4. Bring up interface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.
FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.

Almost all drivers below cfg80211 get the API wrong (except for
cfg80211) and are unable to cope with multiple registrations for
the same frame type, which is valid due to the match filter.
This seems to indicate the API is wrong, and we should maintain
the full information in cfg80211 instead of the drivers.
Change the API to no longer inform the driver about individual
registrations and unregistrations, but rather every time about
the entire state of the entire wiphy and single wdev, whenever
it may have changed. This also simplifies the code in cfg80211
as it no longer has to track exactly what was unregistered and
can free things immediately.

This patch fixes commit 75388acd0c ("add mac80211-based driver for
legacy BCM43xx devices")
In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in
b43legacy is reported. Upon testing, thus problem exists on PPC and
X86 platforms, is present in the oldest kernel tested (3.2), and
has been present in the driver since it was first added to the kernel.
The problem is a corrupted channel status received from the device.
Both the internal card in a PowerBook G4 and the PCMCIA version
(Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2
(revision 4 of the 802.11 core) of the chip has been tested. No other
devices using b43legacy are available for testing.
Various sources of the problem were considered. Buffer overrun and
other sources of corruption within the driver were rejected because
the faulty channel status is always the same, not a random value.
It was concluded that the faulty data is coming from the device, probably
due to a firmware bug. As that source is not available, the driver
must take appropriate action to recover.
At present, the driver reports the error, and them continues to process
the bad packet. This is believed that to be a mistake, and the correct
action is to drop the correpted packet.

We add enable dynamic suspend (autosuspend) support in host driver, and
it can let platform cut down idle power consumption.
To support autosuspend feature in host driver, kernel need to be built
with CONFIG_USB_SUSPEND and autosuspend need to be turn on.
And we also replace wowl feature with adding "needs_remote_wakeup", so
that host still can be waken by wireless device.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Commit 262f2b53f6 ("brcmfmac: call brcmf_attach() just before calling
brcmf_bus_started()") changed the initialization order of the brcmfmac
SDIO driver. Unfortunately since brcmf_sdiod_intr_register() is now
called before the sdiodev->bus_if initialization, it reads the wrong
chip ID and fails to initialize the GPIO on brcm43362. Thus the chip
cannot send interrupts and fails to probe:

The firmware may have SAE authentication code built-in. This is
detected by the driver and indicated in the wiphy features flags.
User-space can use this flag to determine whether or not to provide
the password material for SAE authentication in the nl80211 CONNECT
command.

There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.
Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.

brcmfmac assumed the wifi device always remains powered on and thus
hardcoded the MMC_PM_KEEP_POWER flag expecting the wifi device to
remain on even during suspend/resume cycles.
This is not always the case, some appliances cut power to everything
connected via SDIO for efficiency reasons and this leads to wifi not
being usable after coming out of suspend because the device was not
correctly reinitialized.
So we check for the keep_power capability and if it's not present then
we remove the device and probe it again during resume to mirror what's
happening in hardware and ensure correct reinitialization in the case
when MMC_PM_KEEP_POWER is not supported.

Providing a new wiphy on every PCIe reset was confusing and was causing
configuration problems for some users (supplicant and authenticators).
Sticking to the existing wiphy should make error recovery much simpler

This moves "ops" pointer from "struct brcmf_cfg80211_info" to the
"struct brcmf_pub". This movement makes it possible to allocate wiphy
without attaching cfg80211 (brcmf_cfg80211_attach()). It's required for
later separation of wiphy allocation and driver initialization.
While at it fix also an unlikely memory leak in the brcmf_attach().

Getting RAM info just once per driver's lifetime (during chip
recognition) is not enough as it may get adjusted later (depending on
the used firmware). Subsequent inits may load different firmwares so a
full RAM recognition is required on every PCIe setup. This is especially
important since implementing hardware reset on a firmware crash.
Moreover calling brcmf_chip_get_raminfo() makes sure that RAM core is
up. It's important as having BCMA_CORE_SYS_MEM down on BCM4366 was
resulting in firmware failing to initialize and following error:
[ 65.657546] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: Invalid shared RAM address 0x04000001
This change makes brcmf_chip_get_raminfo() call during chip recognition
redundant for PCIe devices but SDIO and USB still need it and it's a
very small overhead anyway.

In wlc_phy_radio_init_2056(), regs_SYN_2056_ptr, regs_TX_2056_ptr and
regs_RX_2056_ptr may be not assigned, and thus they are still NULL.
Then, they are used on lines 20042-20050:
wlc_phy_init_radio_regs(pi, regs_SYN_2056_ptr, (u16) RADIO_2056_SYN);
wlc_phy_init_radio_regs(pi, regs_TX_2056_ptr, (u16) RADIO_2056_TX0);
wlc_phy_init_radio_regs(pi, regs_TX_2056_ptr, (u16) RADIO_2056_TX1);
wlc_phy_init_radio_regs(pi, regs_RX_2056_ptr, (u16) RADIO_2056_RX0);
wlc_phy_init_radio_regs(pi, regs_RX_2056_ptr, (u16) RADIO_2056_RX1);
Thus, possible null-pointer dereferences may occur.
To avoid these bugs, when these variables are not assigned,
wlc_phy_radio_init_2056() directly returns.
