Commit d068ca2ae2 ("codel: split into multiple files") moved all
Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h
as well.
This is similar to the previous commit, although we don't care as
much about incremental builds after pkt_sched.h was touched itself
it is included by net/sch_generic.h which is modified ~20 times
a year.
This decreases the incremental build size after touching pkt_sched.h
from 1592 to 617 objects.

Since sock.h is modified relatively often (60 times in the last
12 months) it seems worthwhile to decrease the incremental build
work.
CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h.
codel.h is itself included by mac80211 which is included by much of
the WiFi stack and drivers. Removing the net/inet_ecn.h include from
CoDel breaks the dependecy between WiFi and sock.h.
Commit d068ca2ae2 ("codel: split into multiple files") moved all
the code which actually needs ECN helpers out to net/codel_impl.h,
the include can be moved there as well.
This decreases the incremental build size after touching sock.h
from 4999 objects to 4051 objects.
Fix unmasked missing includes in WiFi drivers.

We are seeing below error on QCA6390:
...
[70211.671189] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22
[70212.696154] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22
[70213.092941] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22
...
The reason is that, with commit 734223d784 ("ath11k: change return
buffer manager for QCA6390"), ath11k expects the return buffer manager
(RBM) field of descriptor configured as HAL_RX_BUF_RBM_SW1_BM when
parsing error frames from WBM2SW3_RELEASE ring. This is a wrong change
cause the RBM field is set as HAL_RX_BUF_RBM_SW3_BM.
The same issue also applies to REO2TCL ring though we have not got any
error reported.
Fix it by changing RBM from HAL_RX_BUF_RBM_SW1_BM to HAL_RX_BUF_RBM_SW3_BM
for these two rings.

Similar to the same bug in ath10k, a napi disable w/out it being enabled

The strlcpy should not be used because it doesn't limit the source
length. So that it will lead some potential bugs.
But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.
Thus, replace strlcpy with strscpy.

The regdomain is self-managed type for ath11k, the regdomain info is
reported from firmware, it is not from wireless regdb. Firmware fetch
the regdomain info from board data file before. Currently most of the
regdomain info has moved to another file regdb.bin from board data
file for some chips such as QCA6390 and WCN6855, so the regdomain info
left in board data file is not enough to support the feature which need
more regdomain info.
After download regdb.bin, firmware will fetch the regdomain info from
regdb.bin instead of board data file and report to ath11k. If it does
not have the file regdb.bin, it also can initialize wlan success and
firmware then fetch regdomain info from board data file.
Add download the regdb.bin before download board data for some specific
chip which support supports_regdb in hardware parameters.

When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath11k will check the capability, and if it is enabled then
ath11k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath11k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware and also notifies cfg80211.
This only enable rfkill feature for QCA6390, rfkill_pin is all initialized to 0
for other chips in ath11k_hw_params.

Large pkt_len can lead to out-out-bound memcpy. Current
ath9k_hif_usb_rx_stream allows combining the content of two urb
inputs to one pkt. The first input can indicate the size of the
pkt. Any remaining size is saved in hif_dev->rx_remain_len.
While processing the next input, memcpy is used with rx_remain_len.
4-byte pkt_len can go up to 0xffff, while a single input is 0x4000
maximum in size (MAX_RX_BUF_SIZE). Thus, the patch adds a check for
pkt_len which must not exceed 2 * MAX_RX_BUG_SIZE.

I found the bug using a custome USBFuzz port. It's a research work
to fuzz USB stack/drivers. I modified it to fuzz ath9k driver only,
providing hand-crafted usb descriptors to QEMU.
After fixing the value of pkt_tag to ATH_USB_RX_STREAM_MODE_TAG in QEMU
emulation, I found the KASAN report. The bug is triggerable whenever
pkt_len is above two MAX_RX_BUG_SIZE. I used the same input that crashes
to test the driver works when applying the patch.

IEEE80211_HW_USES_RSS is set in ath11k, then the device uses RSS and
thus requires parallel RX which implies using per-CPU station statistics
in sta_get_last_rx_stats() of mac80211. Currently signal is only set in
ath11k_mgmt_rx_event(), and not set for RX data packet, then it show
signal as 0 for iw command easily.
Change to get signal from firmware and report to mac80211.
For QCA6390 and WCN6855, the rssi value is already in dbm unit, so
don't need to convert it again.

Switching from legacy usage of ieee80211_get_tx_rates() lookup to direct
rate table lookup in struct ieee80211_sta->rates.
The current rate control API allows drivers to directly get rates from
ieee80211_sta->rates. ath5k is currently one of the legacy drivers that
perform translation/merge with the internal rate table via
ieee80211_get_tx_rates provided by rate control API.
For our upcoming changes to rate control API and the implementation of
transmit power control, this patch changes the behaviour. The call to
ieee80211_get_tx_rates and subsequent calls are also avoided. ath5k now
directly reads rates from sta->rates into its internal rate table. Cause
ath5k does not rely on the rate array in SKB->CB, this is not considered
anymore except for the first entry (used for probing).
Tested this on a PCEngines ALIX with CMP9-GP miniPCI wifi card (Atheros
AR5213A). Generated traffic between AP and multiple STAs before and
after applying the patch and simultaneously measured throughput and
captured rc_stats. Comparison resulted in same rate selection and no
performance loss between both runs.

The prima driver facilitates the direct programming of beacon filter tables via
SMD commands.
The purpose of beacon filters is quote:
/* When beacon filtering is enabled, firmware will
* analyze the selected beacons received during BMPS,
* and monitor any changes in the IEs as listed below.
* The format of the table is:
* - EID
* - Check for IE presence
* - Byte offset
* - Byte value
* - Bit Mask
* - Byte reference
*/
The default filter table looks something like this:
tBeaconFilterIe gaBcnFilterTable[12] =
{
{ WLAN_EID_DS_PARAMS, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_ERP_INFO, 0u, { 0u, 0u, 248u, 0u } },
{ WLAN_EID_EDCA_PARAM_SET, 0u, { 0u, 0u, 240u, 0u } },
{ WLAN_EID_QOS_CAPA, 0u, { 0u, 0u, 240u, 0u } },
{ WLAN_EID_CHANNEL_SWITCH, 1u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_QUIET, 1u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 1u, 0u, 248u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 2u, 0u, 235u, 0u } },
{ WLAN_EID_HT_OPERATION, 0u, { 5u, 0u, 253u, 0u } },
{ WLAN_EID_PWR_CONSTRAINT, 0u, { 0u, 0u, 0u, 0u } },
{ WLAN_EID_OPMODE_NOTIF, 0u, { 0u, 0u, 0u, 0u } }
};
Add in an equivalent filter set as present in the prima Linux driver.
For now omit the beacon filter "rem" command as the driver does not have an
explicit call to that SMD command. The filter mask should only count when
we are inside BMPS anyway.
Replicating the ability to program the filter table gives us scope to add and
remove elements in future. For now though this patch makes the rote-copy of the
downstream Linux beacon filter table, which we can tweak as desired from now
on.

In ath11k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().
Fix this bug by adding a check of arg.extraie.ptr.
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_ATH11K=m show no new warnings, and our static
analyzer no longer warns about this code.

For whatever reason, some devices like QCA6390, WCN6855 using ath11k
are not in M3 state during PM resume, but still functional. The
mhi_pm_resume should then not fail in those cases, and let the higher
level device specific stack continue resuming process.
Add an API mhi_pm_resume_force(), to force resuming irrespective of the
current MHI state. This fixes a regression with non functional ath11k WiFi
after suspend/resume cycle on some machines.

Currently there is no validation on the spectral/CFR report
over the db ring buffers from the hardware. Improper/incomplete
DMA by the target can result in invalid data received by host.
Due to this we may populate incorrect data to user space.
This buffer validation support fix this issues by filling some
magic value in the buffer during buffer replenish and check for
the magic value in the buffer received by the target. If host
detect magic value in the received buffer it will drop the buffer.

In full monitor mode, monitor destination ring is read before monitor

status ring is lagging behind, reap the status ring, once the PPDU ID
matches, deliver the MSDU to upper layer. If status PPDU id leading,
reap the mon_dst_ring.
The advantage with full monitor mode is hardware has status buffers
available for all the MPDUs in mon_dst_ring, which makes it possible
to deliver more frames to be seen on sniffer.

In builds with -Warray-bounds, casts from smaller objects to larger
objects will produce warnings. These can be overly conservative, but since
-Warray-bounds has been finding legitimate bugs, it is desirable to turn
it on globally. Instead of casting a u32 to a larger object, redefine
the u32 portion of the header to a separate struct that can be used for
both u32 operations and the distinct header fields. Silences this warning:
drivers/net/wireless/ath/ath6kl/htc_mbox.c: In function 'htc_wait_for_ctrl_msg':
drivers/net/wireless/ath/ath6kl/htc_mbox.c:2275:20: error: array subscript 'struct htc_frame_hdr[0]' is partly outside array bounds of 'u32[1]' {aka 'unsigned int[1]'} [-Werror=array-bounds]

Currently mac80211 will send 3 scan request for each scan of WCN6855,
they are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN6855 will
cache the RNR IE(Reduced Neighbor Report element) which exist in the
beacon of 2.4 GHz/5 GHz of the AP which is co-located with 6 GHz,
and then use the cache to scan in 6 GHz band scan if the 6 GHz scan
is in the same scan with the 2.4 GHz/5 GHz band, this will helpful to
search more AP of 6 GHz. Also it will decrease the time cost of scan
because firmware will use dual-band scan for the 2.4 GHz/5 GHz, it
means the 2.4 GHz and 5 GHz scans are doing simultaneously.
Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN6855 since
it supports 2.4 GHz/5 GHz/6 GHz and it is single pdev which means
all the 2.4 GHz/5 GHz/6 GHz exist in the same wiphy/ieee80211_hw.

If cfg80211 is providing extraie's for a scanning process then ath11k will
copy that over to the firmware. The extraie.len is a 32 bit value in struct
element_info and describes the amount of bytes for the vendor information
elements.
The WMI_TLV packet is having a special WMI_TAG_ARRAY_BYTE section. This
section can have a (payload) length up to 65535 bytes because the
WMI_TLV_LEN can store up to 16 bits. The code was missing such a check and
could have created a scan request which cannot be parsed correctly by the
firmware.
But the bigger problem was the allocation of the buffer. It has to align
the TLV sections by 4 bytes. But the code was using an u8 to store the
newly calculated length of this section (with alignment). And the new
calculated length was then used to allocate the skbuff. But the actual code
to copy in the data is using the extraie.len and not the calculated
"aligned" length.
The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled
was 264 bytes during tests with a QCA Milan card. But it only allocated 8
bytes (264 bytes % 256) for it. As consequence, the code to memcpy the
extraie into the skb was then just overwriting data after skb->end. Things
like shinfo were therefore corrupted. This could usually be seen by a crash
in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus
address).

While running stress tests in roaming scenarios (switching ap's every 5
seconds, we discovered a issue which leads to tx hangings of exactly 5
seconds while or after scanning for new accesspoints. We found out that
this hanging is triggered by ath10k_mac_wait_tx_complete since the
empty_tx_wq was not wake when the num_tx_pending counter reaches zero.
To fix this, we simply move the wake_up call to htt_tx_dec_pending,
since this call was missed on several locations within the ath10k code.

In ath11k, tx of management packet is doing in a work queue. Sometimes
the workqueue does not finish tx immediately, then it lead after the next
step of vdev delete finished, it start to send the management packet to
firmware and lead firmware crash.
ieee80211_set_disassoc() have logic of ieee80211_flush_queues() after
it send_deauth_disassoc() to ath11k, its purpose is make sure the
deauth was actually sent, so it need to change ath11k to match the
purpose of mac80211.
To address these issue wait for tx mgmt as well as tx data packets.

Use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some
open-coded arithmetic in allocator arguments.
Note, that this 'bitmap_zalloc()' divides by BITS_PER_LONG the amount of
memory allocated.
The 'roundup()' used to computed the number of needed long should have
been a DIV_ROUND_UP.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.
Use 'bitmap_zero()' to avoid hand writing it.
