We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.
When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.
We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.
To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

The cleanup of radios during namespace exit has recently been reworked
to directly delete a radio while temporarily releasing the spinlock,

iteration of additional radios.
Move radios about to destroy to a temporary list, and clean that up

When obtaining the firmware capability a buffer is provided of 512
bytes. However, if all features in firmware are supported the buffer
needs to be 565 bytes as otherwise truncated information is retrieved
from firmware. Increasing the buffer to 768 bytes on stack.

In commit 66cffd6daa ("b43: fix transmit failure when VT is switched"),
a condition is noted where the network controller needs to be reset. Note
that this situation happens when running the open-source firmware
(http://netweb.ing.unibs.it/~openfwwf/), plus a number of other special
conditions.
for a different card model, it is reported that this change breaks
operation running the proprietary firmware
(https://marc.info/?l=linux-wireless&m=153504546924558&w=2). Rather
than reverting the previous patch, the code is tweaked to avoid the
reset unless the open-source firmware is being used.

Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragments.
This can happen if the driver grabs one or two fragments for rx ring
refill, while other drivers use (and free up) the remaining fragments.
The 32 KiB higher-order page can only be freed once all users have freed
their fragments.
Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak.

This is done in order not to trig the below warning in
ieee80211_rx_napi:
WARN_ON_ONCE(softirq_count() == 0);
ieee80211_rx_napi requires that softirq's are disabled during
execution.
The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.
Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully

Special HTT RX handling for high latency interfaces.
Since no DMA physical addresses are used in the RX ring
config message (this is not supported by the high latency
devices), no RX ring is allocated.
All RX skb's are allocated by the driver and passed directly
to mac80211 in the HTT RX indication handler.
A nice side effect of this is that no huge buffer will be
allocated with dma_alloc_coherent. On embedded systems with
limited memory resources, the allocation of the RX ring is
prone to fail.
Some tweaks made to "make it work":
Removal of protected bit in 802.11 header frame control field.
The chipset seems to do hw decryption but the frame_control
protected bit is still set.
This is necessary for mac80211 not to drop the frame.

Downloading firmware via BMI protocol takes too long time. For example,
a ~700K bytes firmware takes about 500ms to download via BMI protocol.
This is too long especially in suspend and resume scenario where firmware
is re-downloaded unless WoWLAN is enabled. Downloading firmware via diag CE
can reduce the time to ~40ms for a ~700K bytes firmware binary.
Ath10k driver parses the firmware to segments and downloads the segments
to the specified address directly. If the firmware is compressed or has
unsupported segments, ath10k driver will try BMI download again.
It's tested with QCA6174 hw3.2 and
firmware-6.bin_WLAN.RM.4.4.1-00111-QCARMSWP-1. QCA9377 is also affected.

To download firmware via diag interface, driver needs to write the target
memory space below 1M. It means the bit20 should be zero for the converted
address if the target memory space is below 1M. Otherwise, bit20 is one if
the target address is larger or equal to 1M space.
As downloading firmware via diag interface is only required for qca6174
and qca9377, a new specific function is introduced to convert the target
address to ce address: ath10k_pci_qca6174_targ_cpu_to_ce_addri().
This function supports to convert any target address to ce address.

Delay 1ms is too long for both diag read and write operations.
This is observed when writing a big memory buffer to target or
reading a big memory buffer from target. Take writing/reading
512k bytes as example, the delay itself is 256ms as the maximum
length of every write/read is 2k size.
Reduce the delay to 50us for read and write operations.
Take the ath10k_pci_targ_cpu_to_ce_addr() out of loop and put it
in the beginning of the loop for ath10k_pci_diag_read_mem().
The ath10k_pci_targ_cpu_to_ce_addr() is to convert the address
from target cpu's perspective to CE's perspective, so it makes
no sense to convert a CE's perspective address again in the loop.
It's a wrong implementation but happens to work.
If the target address is below 1M space, then the convert in the loop
from the second time becomes wrong because the previously converted address
is larger than 1M. The counterpart ath10k_pci_diag_write_mem() has the
correct implementation.
With this change, ath10k_pci_diage_read_mem() works correctly no matter
the target address is below 1M or above 1M.
It's tested with QCA6174 hw3.2 and

To support dual-band variant of QCA9984, new extended board data (eBDF)
is introduced since existing board data ran out of space.
Below is the brief implementation & design detail,
----------------------------------------------------
1. New OTP changes to inform eBDF support in existing OTP download to
fetch board ID and chip ID. This is backward compatible and older
card sends 0 by default for eBDF support bit (bit 18 of OTP response) we
check in ath10k driver.
2. If eBDF is supported, then we need to fetch eBDF ID which is bundled
in downloaded board data. So again OTP is executed for knowing the eBDF ID.
This is done once we set 'board_data_initialized' bit. If eBDF ID
returned is zero, we continue booting with previous board data downloaded.
3. Based on the eBDF ID fetched, ath10k driver tries to download the
extended board data to a new offset ahead of already downloaded board
data address.
4. A new BD IE type, ATH10K_BD_IE_BOARD_EXT is added to differentiate in
bundling eBDF separately in board-2.bin and also to parse through
board bundle for eBDF download in ath10k boot.
5. If eBDF is not present in the board-2.bin bundle or when board ID is
zero, we do a fallback boot to "eboard.bin" in the same QCA9984/hw1.0 dir.
This is same as done to existing "board.bin" if board ID is not present
in board-2.bin bundle.
Current design is that eBDF size will be 2KB and eBDF ID will be
byte value.
Tested the above changes with dual-band variant of QCA9984 card. OTP
update needed for the test will be part of next FW release 10.4-3.6-xxxx.
Below are the logs with ath10k BOOT debugs enabled.

After add the waiting htt tx complete, then firmware will have some

strnchr takes arguments in the order of its name: string, max bytes to
read, character to search for. Here we're passing '\n' aka 10 as the
buffer size, and searching for sizeof(buf) aka BRCMF_DCMD_SMLEN aka
256 (aka '\0', since it's implicitly converted to char) within those 10
bytes.
Just interchanging the last two arguments would still leave a bug,
because if we've been successful once, there are not sizeof(buf)
characters left after the new value of p.
Since clmver is immediately afterwards passed as a %s argument, I assume
that it is actually a properly nul-terminated string. For that case, we
have strreplace().

USB suspend handler will kill the presubmitted rx_cmd URB. This
triggers a call to the corresponding URB complete handler, which
will free the rx_cmd skb, associated with rx_cmd URB. Due to a
possible race betwen suspend handler and main thread, depicted in
'commit bfcacac6c84b ("mwifiex: do no submit URB in suspended
state")', it is possible that the rx_cmd skb will fail to get
freed. This causes a memory leak, since the resume handler will
always allocate a new rx_cmd skb.
To fix this, free the rx_cmd skb in mwifiex_usb_submit_rx_urb, if
the device is in suspended state.

There is a possible race between USB suspend and main thread:
1. After processing the command response, main thread will submit
rx_cmd URB back so as to process next command response, by
calling mwifiex_usb_submit_rx_urb.
2. During USB suspend, the suspend handler will check if rx_cmd
URB is pending(submitted) and if true, kill this URB.
There is a possible race between #1 and #2, where rx_cmd URB will
be submitted by main thread(#1) after the suspend handler check
in #2.
To fix this, check if device is already suspended in
mwifiex_usb_submit_rx_urb, in which case do not submit the URB.

When the NIC is disconnected, we just can't do anything
besides seeking for help from the bus driver. Dumping the
device's memory is not necessary and just bloats the logs
with unusable data. Moreover, asking mac80211 to restart
the hardware is also useless. Bypass all this.
Also, use the STATUS_TRANS_DEAD status bit instead of a
bool inside the transport layer. The advantage of this is
that now, the transport and the op_mode can know what is the
situation and bypass the useless recovery steps mentioned
above.

When the NIC is disconnected from PCI bus, we are not
able to access it anymore. Check the status to avoid
some unnecessary work so can improve the performance.
It will help to make PCI bus rescan to bring back the
device much faster.
The real test is able to improve 7 seconds.

There's no point in warning here, the user will just get an
error back to the debugfs file write, and warning just makes
it seem like there's an internal consistency problem when in
reality the user just happened to hit this at a bad time.
Remove the warning.

Every rx mpdu cmd is built from cmd_hdr | 80211_hdr. The problem is
that the size of cmd_hdr changes with API changes and we don't know
where the 80211_hdr starts.
By adding the size of cmd_hdr dynamically, we can ensure that we always
know how to parse mpdu frames, without dependending on the API changes.
