Whenever the signal stregth decays smoothly and physical connnection
is already gone and no deauth has arrived, the qcom soc is not
able to indicate neither WCN36XX_HAL_MISSED_BEACON_IND nor
WCN36XX_HAL_MISSED_BEACON_IND. It was noticed that such situation gets
even more reproducible, when the driver fails to enter bmps mode - which is
highly likely to occur. Thus, in order to provide proper disconnection
of the connected STA, let mac80211 handle it, instead of wcn3xx driver.

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.

clang triggers a warning about oversized stack frames that gcc does not
notice because of slightly different inlining decisions:
ath/wcn36xx/smd.c:1409:5: error: stack frame size of 1040 bytes in function 'wcn36xx_smd_config_bss' [-Werror,-Wframe-larger-than=]
ath/wcn36xx/smd.c:640:5: error: stack frame size of 1032 bytes in function 'wcn36xx_smd_start_hw_scan' [-Werror,-Wframe-larger-than=]
Basically the wcn36xx_hal_start_scan_offload_req_msg,
wcn36xx_hal_config_bss_req_msg_v1, and wcn36xx_hal_config_bss_req_msg
structures are too large to be put on the kernel stack, but small
enough that gcc does not warn about them.
Use kzalloc() to allocate them all. There are similar structures in other
parts of this driver, but they are all smaller, with the next largest
stack frame at 480 bytes for wcn36xx_smd_send_beacon.

We currently have two levels of strict validation:
1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size
The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().
Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.
We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.
Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.
Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.
In effect then, this adds fully strict validation for any new command.

Introduce infrastructure for supporting Factory Test Mode (FTM) of the
wireless LAN subsystem. In order for the user space to access the
firmware in test mode the relevant netlink channel needs to be exposed
from the kernel driver.
The above is achieved as follows:
1) Register wcn36xx driver to testmode callback from netlink
2) Add testmode callback implementation to handle incoming FTM commands
3) Add FTM command packet structure
4) Add handling for GET_BUILD_RELEASE_NUMBER (msgid=0x32A2)
5) Add generic handling for all PTT_MSG packets

Like on the TX side, check for the interrupt reason when the RX interrupt
is latched and clear the ERR, DONE and ED masks.
This seems to help with connection timeouts and network stream
starvatations. And FWIW, the downstream driver does the same thing.
Note that in analogy to the TX side, WCN36XX_DXE_0_INT_CLR should be set to
WCN36XX_INT_MASK_CHAN_RX_{L,H} rather than WCN36XX_DXE_INT_CH{1,3}_MASK. It
did the right thing however, as the defines happen to have identical values.
Also, instead of determining register addresses and values inside
wcn36xx_rx_handle_packets(), pass them as arguments.

When wcn36xx_dxe_tx_frame() is entered while the device is still processing
the queue asyncronously, we are racing against the firmware code with
updates to the buffer descriptors. Presumably, the firmware scans the ring
buffer that holds the descriptors and scans for a valid control descriptor,
and then assumes that the next descriptor contains the payload. If, however,
the control descriptor is marked valid, but the payload descriptor isn't,
the packet is not sent out.
Another issue with the current code is that is lacks memory barriers before
descriptors are marked valid. This is important because the CPU may reorder
writes to memory, even if it is allocated as coherent DMA area, and hence
the device may see incompletely written data.
To fix this, the code in wcn36xx_dxe_tx_frame() was restructured a bit so
that the payload descriptor is made valid before the control descriptor.
Memory barriers are added to ensure coherency of shared memory areas.

When the wifi driver core passes IE elements in the scan request, append
them to the firmware message. The driver currently tells the core that
it is capable of attaching up to WCN36XX_MAX_SCAN_IE_LEN octets, but
doesn't actually pass them to the the hardware.
Note that this patch doesn't fix a bug that was observed. The change is
merely done for the sake of completeness as the hardware supports
appending IEs in scans. Tests show that network scans work fine with

The firmware message to delete BSS keys expects a BSS index to be passed.
This field is currently hard-coded to 0. Fix this by passing in the index
we received from the firmware when the BSS was configured.
The encryption type in that message also needs to be set to what was used
when the key was set, so the assignment of vif_priv->encrypt_type is now
done after the firmware command was sent. This reportedly fixes the
following error in AP mode:
wcn36xx: ERROR hal_remove_bsskey response failed err=6
Also, AFAIU, when a BSS is deleted, the firmware apparently drops all the
keys associated with it. Trying to remove the key explicitly afterwards
will hence lead to the following message:
wcn36xx: ERROR hal_remove_bsskey response failed err=16
This is now suppressed with an extra check for the BSS index validity.

When accessing shared memory to check for the stat of submitted
descriptors, make sure to use READ_ONCE(). This will guarantee the
compiler treats these memory locations as volatile and doesn't apply
any caching.
While this doesn't fix any particular problem I ran into, it's best
practice to do it this way.
Note that this patch also removes the superflous extra condition check
in the do-while loop in reap_tx_dxes(), as the loop will break

The firmware code cannot cope with requests to remove BSS indices that have
not previously been added. This primarily happens when the device is
suspended and then resumed. ieee80211_reconfig() then calls into
wcn36xx_bss_info_changed() with an empty bssid and BSS_CHANGED_BSSID set,
which subsequently leads to a firmware crash:
[ 43.647928] qcom-wcnss-pil a204000.wcnss: fatal error received: halMsg.c:4964:halMsg_DelBss: Invalid BSSIndex 0

When wcn36xx_dxe_tx_frame() fails to transmit the TX frame, the driver
will call into ieee80211_free_txskb() for the skb in flight, so it'll no
longer be valid. Hence, we shouldn't keep a reference to it in ctl->skb.
Also, if the skb has IEEE80211_TX_CTL_REQ_TX_STATUS set, a pointer to
it will currently remain in wcn->tx_ack_skb, which will potentially lead
to a crash if accessed later.
Fix this by checking the return value of wcn36xx_dxe_tx_frame(), and
nullify wcn->tx_ack_skb again in case of errors. Move the assignment
of ctl->skb in wcn36xx_dxe_tx_frame() so it only happens when the
transmission is successful.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked
section minimal.
