Subject: [PATCH 02/91] ath10k: print htt op_version upon driver boot

HTT version itself isn't sufficient to know what
HTT version given firmware blob uses. Hence print
the recently introduced HTT op version code.

While at it make the info string a bit more
consistent and clear.

Subject: [PATCH 03/91] ath10k: enable VHT for IBSS

Enable VHT support for IBSS, while mac80211/cfg80211 and
wpa_supplicant already support this.

In my test env, qca988x 2x2 I get:

(udp) ath10k-1 >>>> ath10k-2 (server) -  speed: 419 Mbits/sec
(tcp) ath10k-1 >>>> ath10k-2 (server) -  speed: 404 Mbits/sec

During tests I used wpa_supplicant (latest git version), which
already support IBSS VHT, and choose highest available BW. Also tested with
qca6174.

Subject: [PATCH 10/91] ath10k: Add hw register/values for QCA99X0 chip

This is to prepare the driver for QCA99X0 chip support.
This commit adds hw_params, hw register table and hw_values
table for QCA99X0 chip. Please note this is only a partial patch adding
support for QCA99X0, so the device id is not yet added to pci device
table.

Subject: [PATCH 11/91] ath10k: Copy Engine related changes for QCA99X0

QCA99X0 supports upto 12 Copy engines. Host and target
CE configuration table is updated to support new copy engine
pipes. This also fixes the assumption of diagnostic CE by making
CE_7 as the one instead of CE_COUNT - 1.

Subject: [PATCH 14/91] ath10k: Extend CE src desc flags for interrupt
 indication

QCA99X0 uses two new copy engine src desc flags for interrupt
indication. Bit_2 is to mark if host interrupt is disabled after
processing the current desc and bit_3 is to mark if target interrupt
is diabled after the processing of current descriptor.
CE_DESC_FLAGS_META_DATA_MASK and CE_DESC_FLAGS_META_DATA_LSB are based
on the target type.

Subject: [PATCH 15/91] ath10k: Fix BMI communication timeout for QCA99X0

There is more than 1 sec delay in getting response from target
through BMI in QCA99X0. Increase the BMI communication timeout
to 2*HZ to fix BMI failures.

Subject: [PATCH 16/91] ath10k: Add support for code swap

Code swap is a mechanism to use host memory to store
some fw binary code segment. Ath10k host driver allocates
and loads the code swap binary into the host memory and
configures the target with the host allocated memory
information at the address taken from code swap binary.
This patch adds code swap support for firmware binary.
Code swap binary for firmware bin is available in
ATH10K_FW_IE_FW_CODE_SWAP_IMAGE.

Subject: [PATCH 18/91] ath10k: include new wmi op version for 10.4 fw

qca99X0 chip uses firmware version 10.4. Define a new macro
ATH10K_FW_WMI_OP_VERSION_10_4 for 10.4 firmware and include
in switch cases where ATH10K_FW_WMI_OP_VERSION_* is used
to avoid compilation error.

Subject: [PATCH 20/91] ath10k: include 10.4 fw specific wmi cmd and event ids

10.4 firmware wmi cmd and event id values are not exactly aligned
with previous firmware versions (main, 10.x, 10.2, etc). Add new
enum to define wmi cmd & event definitions for 10.4 firmware and
prepare wmi_10_4_cmd_map based on 10.4 firmware wmi cmd definitions.

wmi_cmd_map is extended to accommodate new wmi commands which are
exclusively available in 10.4 firmware.

Subject: [PATCH 21/91] ath10k: set 10.4 fw exclusive wmi cmd as unsupported
 for other fw versions

In fact, explicit assigned to ZERO for unsupported wmi commands
are not really needed. Global static variable will have ZERO by
default. However, just for better readability setting all wmi cmds
in non 10.4 firmware wmi mapping table as unsupported for wmi cmd
which are exclusively available only in 10.4 firmware.

Subject: [PATCH 22/91] ath10k: add 10.4 fw wmi vdev cmd ids

Include 10.4 firmware wmi vdev cmd id and make up wmi vdev map
table wmi_10_4_vdev_param_map and also update non 10.4 firmware
vdev cmd map table with newly added vdev cmd id specifically for
10.4 firmware as unsupported.

Subject: [PATCH 24/91] ath10k: fill 10.4 fw wmi init cmd default values

Define 10.4 wmi init command structure and introduce new function
ath10k_wmi_10_4_op_gen_init() to fill default values for each field
which goes as part of wmi init cmd to 10.4 firmware.

Subject: [PATCH 25/91] ath10k: handle 10.4 fw wmi mgmt rx event

10.4 firmware wmi mgmt rx event format differs from non 10.4
firmware and changing existing wmi mgmt rx event parsing function
ath10k_wmi_op_pull_mgmt_rx_ev() for 10.4 would add more complex.

This patch adds new function to receive any wmi rx event from
10.4 firmware and also introduce new function to parse wmi mgmt
rx event.

In addition, fw main branch service rdy event parsing function
is linked in wmi ops table.

Subject: [PATCH 26/91] ath10k: adjust default peer limits if qcache enabled in
 10.4 fw

10.4 firmware supports upto 512 clients when qcache feature is enabled.
Make adjustment on default max peer count, active peers, number of tid in
such case to meet qcache requirement. 10.4 fw has extra unit info flag
NUM_UNITS_IS_NUM_ACTIVE_PEERS which is also handled in this patch.

Subject: [PATCH 28/91] ath: DFS - limit number of potential PRI sequences

In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.

Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.

This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.

Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

Subject: [PATCH 29/91] wil6210: restart AP upon change in privacy settings

privacy settings might change while AP is running.
Inside wil_cfg80211_change_beacon(), detect change
in privacy settings and handle it by stopping and
re-starting the AP.
Firmware cannot handle on-the-fly privacy settings
change and so AP restart is required.

Subject: [PATCH 30/91] ath10k: enhance swba event handler to adapt different
 size tim bitmap

Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.

Subject: [PATCH 31/91] ath10k: handle 10.4 firmware wmi swba event

10.4 firmware swba event payload has space to accommodate upto
512 client traffic indication info & one p2p noa descriptor.
It's is not matching with exiting swba event format defined for
non 10.4 firmware. Non 10.4 firmware swba event format is designed
to support only upto only 128 client and four p2p notice of absence
descriptor.

following changes are done in this patch to enable ath10k to handle
10.4 firmware swba event,

 - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
   event in 10.4 wmi rx handler.

 - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

 - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
   10.4 swba event.

 - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
   power save state.

Subject: [PATCH 32/91] ath10k: enable vdev and peer related operations for
 10.4 fw

Most of existing vdev and peer related functions (vdev create,
vdev delete, vdev start, peer create, peer delete, peer flush, etc)
are reusable for 10.4 firmware. Link those general vdev and peer
functions to 10.4 wmi function table.

Existing general pktlog enable/disable, dbglog configuration functions
are reusable for 10.4 and add them also in wmi function table.

Also handle few wmi events (sevice rdy, echo, dbg msg, tbtt offset
update, dbg print) in ath10k_wmi_10_4_op_rx(). wow event is not
applicable in 10.4 firmware, have it under not implemented print.

Subject: [PATCH 33/91] ath10k: add scan support for 10.4 fw

Existing non 10.4 firmware scan related events and commands are
matching with 10.4 firmware (except chan info event). Link general
start scan,stop scan, scan channel list configuration functions
to 10.4 wmi function table and add a new handler to parse 10.4
specific chan info event.

10.4 firmware has extra scan completion reason
WMI_SCAN_REASON_INTERNAL_FAILURE and new scan event
WMI_SCAN_EVENT_FOREIGN_CHANNEL_EXIT compared to previous firmware
versions. These things are added in respective enum.

Subject: [PATCH 37/91] ath10k: configure frag desc memory to target for
 qca99X0

Pre qca99X0 chipsets follows the model where dynamically allocate
memory for frag desc on getting new skb for TX. But, this is not
going to be the case in qca99X0. It expects frag desc memory to be
allocated at boot time and let the driver to reuse allocated memory
after every TX completion. So there won't be any dynamic frag memory
memory allocation in qca99X0 during data transmission.

qca99X0 hardware doesn't need fragment desc address to be programmed
in msdu descriptor for every data transaction. It needs to know only
starting address of fragment descriptor at the time of the boot.
During data transmission, qca99X0 hardware can retrieve corresponding
frag addr by adding programmed frag desc base addr + msdu id.

Allocate continuous fragment descriptor memory (same size as number of
descriptor) at the time of target initialization and configure allocated
dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.

How this is allocated continuous memory is going to be used is not
covered in this patch. It just allocates memory and hand over to firmware.
If we don't do it at init time, qca99X0 will stall when firmware tries
to do TX.

Subject: [PATCH 38/91] ath10k: fix QCA61X4 boot up

commit a521ee983d312db7 ("ath10k: Add new reg_address/mask to hw register
table") broke QCA61x4 support by providing wrong
fw_indicator_address, which should have been 0x0003a028 instead of 0x00009028.

User experience was a failing boot up sequence (crashing device during
initialization):

[  181.663874] ath10k_pci 0000:02:00.0: enabling device (0000 -> 0002)
[  181.664787] ath10k_pci 0000:02:00.0: pci irq msi-x interrupts 8 irq_mode 0 reset_mode 0
[  181.688886] ath10k_pci 0000:02:00.0: device has crashed during init
[  181.688897] ath10k_pci 0000:02:00.0: failed to wait for target after cold reset: -70
[  181.688902] ath10k_pci 0000:02:00.0: failed to reset chip: -70
[  181.689774] ath10k_pci: probe of 0000:02:00.0 failed with error -70

Fix it by updating the address with correct value.

Subject: [PATCH 41/91] ath10k: limit multi-vif ps more aggresivelly

Further testing proved that multi-channel AP+STA
on QCA6174 with RM.2.0-00088 should have powersave
force-disabled to avoid beacon misses/skipping on
either side which in turn could disrupt
communication.

Since AP never has arvif->ps don't even bother
checking it. Other combinations may be broken as
well so disallow powersave with multivif outright
unless firmware advertises otherwise.

since fcf9844636be ("ath10k: fix hw roc
expiration") the notification was never sent when
roc actually expired.

This fixes some P2P connection setup issues.

Subject: [PATCH 43/91] ath10k: update vdev ps state on start

Psmode can be forcefully enabled when vdev isn't
started. It isn't guaranteed that mac80211 will
re-issue psmode setting after vdev is started
unless actual bss_conf.ps value has changed.

Even if this doesn't fix any problems now it may
prevent future breakage.

Subject: [PATCH 44/91] ath10k: fix per-vif queue locking

Whenever any vdev was supposed to be paused all Tx
queues were stopped (except offchannel) instead of
only these associated with the given vdev.

This caused subtle issues with
multi-channel/multi-vif scenarios, e.g.
authentication of station vif could sometimes fail
depending on fw tx pause request timing.

Also tune the way station and p2p client interface
limits are expressed to allow station + 2x p2p
client or station + p2p client + p2p go.

Subject: [PATCH 48/91] ath9k: DFS - add pulse chirp detection for FCC

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Subject: [PATCH 50/91] mwifiex: add tx data pause support

This patch adds support to enable TX data pause feature for mwifiex.
Whenever FW TX buffers reach threshold, FW would send TX pause event
to driver. Driver in turn would block data traffic to that particular
receiver address.

Subject: [PATCH 52/91] mwifiex: do not increase tx_pkts_queued if receive
 address tx paused

If tx_pkts_queued is increased for tx paused receive address, tx process
will be triggered for this packet. But since RA list was tx paused,
there will be an infinite loop in mwifiex_wmm_process_tx waiting for the
event(tx pause, tdls cs) to cancel tx pause. This will be an dead loop,
since main_process was locked at this time, there will be no opportunity
to process event.

So do not increase tx_pkts_queued if receive address tx paused,
this will be restored RA list is unpaused.

Subject: [PATCH 54/91] mwifiex: process tdls channel switch event

This patch add support for tdls channel switch event process.
We block TX queues for particular RA list depending upon channel
switch state. If channel switch state is moving to base channel,
we unblock RA lists for AP. If channel switch state is moving to off
channel, we unblock TDLS peer RA lists.

Subject: [PATCH 59/91] mwifiex: update domain_info upon band change in
 start_ap

It was observed that AP beacons would not reflect correct regulatory
information upon starting AP in A band. This was because of missing
AP config band update in set_channel of start_ap. Also we configure 11D
settings info FW only for specific band. So we need to download domain
info to FW even if domain remains unchanged but band is changed.

Subject: [PATCH 60/91] mwifiex: support for bypass tx queue

This patch adds support for another TX queue in driver- bypass
TX queue. This queue is used for sending data/mgmt packets while
in disconnected state i.e. when port is yet not unblocked.
TDLS setup packets would also be queued in this queue.

Subject: [PATCH 64/91] mwifiex: advertise multichannel support to cfg80211

This patch adds support to advetise mwifiex multichannel support to
cfg80211. If module parameter drcs is enabled and FW supports multichannel
operation we advertise this support to cfg80211. As of now 2 simultaneous
channels are supported.

Subject: [PATCH 65/91] mwifiex: separate interface combination for
 multichannel and DFS

Multichannel and DFS cannot be supported at same time. So when multichannel
operation is enabled by module parameter, we enable number of channel as 2
while registering wiphy. For all other cases we advertise DFS support to
cfg80211. Patch also adds support for radar detect widths parameter.

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

Subject: [PATCH 68/91] mwifiex: avoid freeing improper pointer in
 mwifiex_set_wowlan_mef_entry

mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in
case of an error.  The only caller (mwifiex_set_mef_filter) passes that
pointer as an offset into allocated memory, so any attempt to free that
will not be the actual allocated pointer.

Address this by changing mwifiex_set_wowlan_mef_entry to not do any
free, and to cause mwifiex_set_mef_filter to do the appropriate free if
the call to mwifiex_set_wowlan_mef_entry fails.

Subject: [PATCH 72/91] mwifiex: usb: Fix double add error when submitting rx
 urb

There is an error that can occur where the driver adds the same URB to USB submission list twice.
This happens since mwifiex_usb_submit_rem_rx can submit packets at same time as an rx urb complete callback.
This causes list corruption and is fixed by not setting the skb to NULL when submitting an rx packet.

Subject: [PATCH 76/91] ath9k: make DMA stop related messages debug-only

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.

Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.

To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

Subject: [PATCH 77/91] mwifiex: fix for p2p broken link

This patch fixes following issues in p2p code paths.

1) bss role, bss type and connection type was not set correctly
for p2p GO and p2p client at couple of places.
2) Driver appends a proprietary header to management frames
which will be parsed by our firmware. Later while informing
TX status to cfg80211, modified frame buffer was passed to
cfg80211_mgmt_tx_status() instead of original one.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Our bus should allow defining children nodes as we may want to specify
devices attached to the bus. This is required e.g. to specify NAND or
ChipCommon cores and use bus's address and IRQ mappings.

Subject: [PATCH 79/91] rtlwifi: rtl8821ae: Fix an expression that is always
 false

In routine _rtl8821ae_set_media_status(), an incorrect mask results in a test
for AP status to always be false. Similar bugs were fixed in rtl8192cu and
rtl8192de, but this instance was missed at that time.

Subject: [PATCH 81/91] ath9k: fix moredata flag endianness in cabq tx

While compiling ath9k with some extra flags I've
found that:

 ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer
 ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=
 ath9k/xmit.c +2474 ## 36:    left side has type restricted __le16
 ath9k/xmit.c +2474 ## 36:    right side has type int

There's no way for frame ftype/stype to be
mistreated as the offending 'moredata' flag when
considering cab queue.

This could've however theoretically led sometimes
to increased power consumption on connected
stations as they would keep their Rx active
waiting for frames that would never come.

Subject: [PATCH 82/91] brcmfmac: set wiphy's addresses to provide valid MACs

Broadcom's firmware requires every BSS to use MAC address with unique
last few bits. The amount of bits may depend on a particular firmware,
it was verified to be 2 for BCM43602 one.
If this condition won't be fulfilled firmware will reject such MAC:
brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52

We don't want to simply set addr_mask as it would also disallow using
locally administrated bit. Instead let's build a list of addresses
manually enabling 0x2 bit for extra interfaces.

We measured the FFT-based entropy in 3 ways, Shannon entropy,
collision entropy, and directly measured min-entropy. Just to
be conservative, we recommend the estimated min-Entropy to be
10 bits per 16-bit value.

Analysis was done by Jacobson,David(djacobso@qti.qualcomm.com).

Subject: [PATCH 86/91] iwlegacy: convert hex_dump_to_buffer() to %*ph

There is no need to use hex_dump_to_buffer() in the cases like this:

	hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);	/* len <= 16 */
	sprintf("%s\n", outbuf);

since it maybe easily converted to simple:

	sprintf("%*ph\n", len, buf);

Note: it seems in the case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

This reverts commit 6301566e0b2dafa7d6779598621bca867962a0a2. Oleksij Rempel
noticed that the randomness doesn't look to be good enough and Stephan Mueller
commented:

"I would say that the discussed RNG does not seem fit for hooking it up with the
hwrandom framework."

http://lkml.kernel.org/g/3945775.m5HblJPgiO@tauon.atsec.com

So let's the revert the patch until we are sure that we can trust this random
generator.
