[PATCH 01/12] ath11k: Fix pktlog lite rx events

[PATCH 01/12] ath11k: Fix pktlog lite rx events

[Jouni Malinen]

From: Anilkumar Kolli <akolli@codeaurora.org>

Fix sending rx_buf_sz to ath11k_dp_tx_htt_rx_filter_setup()
to enable pktlog full or lite mode. Depending on mode update the
trace buffer with log type full/lite.

Pktlog lite is a lighter version of pktlog. This can be used to capture
PPDU stats. These are useful for firmware performance debugging.

pktlog lite dumps are enabled using,
  echo "0x0 1" > ath11k/IPQ8074 hw2.0/mac0/pktlog_filter

Tested On: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01233-QCAHKSWPL_SILICONZ-1 v2

[PATCH 02/12] ath11k: Update pdev tx and rx firmware stats

[Jouni Malinen]

From: Sriram R <srirrama@codeaurora.org>

Update the fields of pdev tx and tx firmware stats structure.
Missing fields resulted in wrong fw stats to be displayed as below.

root@OpenWrt:/# cat /sys/kernel/debug/ath11k/
		ipq8074\ hw2.0/mac0/fw_stats/pdev_stats | grep Illegal
Illegal rate phy errors   36839112

Note that this struct was missing its members from initial driver
support and this change doesn't introduce/modify the structure for
firmware changes.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1 v2

[PATCH 03/12] ath11k: Avoid reg rules update during firmware recovery

[Jouni Malinen]

From: Sriram R <srirrama@codeaurora.org>

During firmware recovery, the default reg rules which are
received via WMI_REG_CHAN_LIST_CC_EVENT can overwrite
the currently configured user regd.

See below snap for example,

root@OpenWrt:/# iw reg get | grep country
country FR: DFS-ETSI
country FR: DFS-ETSI
country FR: DFS-ETSI
country FR: DFS-ETSI

root@OpenWrt:/# echo assert > /sys/kernel/debug/ath11k/ipq8074\ hw2.0/simulate_f
w_crash
<snip>
[ 5290.471696] ath11k c000000.wifi1: pdev 1 successfully recovered

root@OpenWrt:/# iw reg get | grep country
country FR: DFS-ETSI
country US: DFS-FCC
country US: DFS-FCC
country US: DFS-FCC

In the above, the user configured country 'FR' is overwritten
when the rules of default country 'US' are received and updated during
recovery. Hence avoid processing of these rules in general
during firmware recovery as they have been already applied during
driver registration or after last set user country is configured.

This scenario applies for both AP and STA devices basically because
cfg80211 is not aware of the recovery and only the driver recovers, but
changing or resetting of the reg domain during recovery is not needed so
as to continue with the configured regdomain currently in use.

[PATCH 04/12] ath11k: Avoid race during regd updates

[Jouni Malinen]

From: Sriram R <srirrama@codeaurora.org>

Whenever ath11k is bootup with a user country already set, cfg80211
notifies this country info to ath11k soon after registration, where the
notification is sent to the firmware for fetching the rules of this user
country input.

Multiple race conditions could be seen in this scenario where a new
request is either lost as pointed in [1] or a new regd overwrites the
default regd provided by the firmware during bootup. Note that, the
default regd is used for intersection purpose and hence it should not be
overwritten.

The main reason as pointed by [1] is the usage of ATH11K_FLAG_REGISTERED
flag which is updated after completion of core registration, whereas the
reg notification from cfg80211 and wmi events for the corresponding
request can happen much before that. Since the ATH11K_FLAG_REGISTERED is
currently used to determine if the event containing reg rules belong to
default regd or for user request, there is a possibility of the default
regd getting overwritten.

Since the default reg rules will be received only once per pdev on
firmware load, the above flag based check can be replaced with a check
to see if default_regd is already set, so that we can now always update
the new_regd. Also if the new_regd is set, this will be always used to
update the reg rules for the registered phy.

[PATCH 05/12] ath11k: Add vdev start flag to disable hardware encryption

[Jouni Malinen]

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

Firmware blocks all data traffic until the key is plumbed. But, with
software encryption mode, key is never plumbed to firmware. Due to this,
a traffic failure in software encryption mode has been observed. Hence,
firmware has introduced a flag to differentiate software encryption
mode. This flag can be passed during vdev_start command.

Enable WMI_VDEV_START_HW_ENCRYPTION_DISABLED flag in vdev_start command
to notify firmware to disable hardware encryption for a vdev. This is set
if raw mode software encryption is enabled.

[PATCH 06/12] ath11k: Assign free_vdev_map value before ieee80211_register_hw

[Jouni Malinen]

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

Firmware crash is seen randomly, because of sending wrong vdev_id
in vdev_create command. This is due to free_vdev_map value being 0.
free_vdev_map is getting assigned after ieee80211_register_hw. In
some race conditions, add_interface api is getting called before
assigning value to free_vdev_map. Fix this by assigning free_vdev_map
before ieee80211_register_hw.

Also, moved ar->cc_freq_hz and ar->txmgmt_idr initialization before
ieee80211_register_hw to avoid such race conditions.

[PATCH 07/12] ath11k: Fix crash during firmware recovery on reo cmd ring access

[Jouni Malinen]

From: Sriram R <srirrama@codeaurora.org>

In scenario when a peer is disassociating, there could be
multiple places where a reo cmd ring is accessed, such as
during aggregation teardown, tid queue cleanup, etc.

When this happens during firmware recovery where accessing of FW/HW
resources/registers is not recommended, accessing reo cmd ring in
this case could lead to crash or undefined behaviour.

Hence avoid this by checking for corresponding flag to avoid
accessing reo cmd ring during firmware recovery.

Sample crash:

[PATCH 08/12] ath11k: Avoid "No VIF found" warning message

[Jouni Malinen]

From: Karthikeyan Periyasamy <periyasa@codeaurora.org>

Facing below warning prints when we do wifi down in multiple VAPs scenario.

warning print:

ath11k c000000.wifi: No VIF found for vdev 2
...
ath11k c000000.wifi: No VIF found for vdev 0

In ath11k_mac_get_arvif_by_vdev_id(), we iterate all the radio to get the
arvif for the requested vdev_id through ath11k_mac_get_arvif().
ath11k_mac_get_arvif() throws a warning message if the given vdev_id is
not found in the given radio. So to avoid the warning message, add
the allocated_vdev_map cross check against the given vdev_id before using
ath11k_mac_get_arvif() to ensure that vdev_id is allocated in the
given radio.

[PATCH 09/12] ath11k: Add wmi peer create conf event in wmi_tlv_event_id

[Jouni Malinen]

From: P Praneesh <ppranees@codeaurora.org>

When the driver sends a peer create cmd, the firmware responds with
WMI_PEER_CREATE_CONF_EVENTID to confirm the firmware received
WMI_PEER_CREATE_CMDID. Since the peer create conf event is not handled
in ath11k_wmi_tlv_op_rx, we are getting unknown event id warning prints
during peer creation.

Add WMI_PEER_CREATE_CONF_EVENTID in wmi_tlv_event_id and handle
the same as unsupported event id under wmi logs.

[PATCH 10/12] ath11k: Send PPDU_STATS_CFG with proper pdev mask to firmware

[Jouni Malinen]

From: Rameshkumar Sundaram <ramess@codeaurora.org>

HTT_PPDU_STATS_CFG_PDEV_ID bit mask for target FW PPDU stats request
message was set as bit 8 to 15. Bit 8 is reserved for soc stats and
pdev id starts from bit 9. Hence change the bitmask as bit 9 to 15
and fill the proper pdev id in the request message.

Tested on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01092-QCAHKSWPL_SILICONZ-1
Tested on: IPQ6018 hw1.0 WLAN.HK.2.5.0.1-01067-QCAHKSWPL_SILICONZ-1

Fixes: 701e48a43e15 ("ath11k: add packet log support for QCA6390")

[PATCH 11/12] ath11k: Clear auth flag only for actual association in security mode

[Jouni Malinen]

From: Lavanya Suresh <lavaks@codeaurora.org>

AUTH flag is needed when peer assoc command is sent from the host in
security mode for non-assoc cases. The firmware will handle AUTH flag
when the client is associating as AUTH flag will be set after key
exchange. For internally provided peer assoc commands from the host,
there won't be any key exchange, so AUTH flag is expected to be set in
the host.

[PATCH 12/12] ath11k: Change QCN9074 firmware to operate in mode-2

[Jouni Malinen]

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

In mode-2 QCN9074 firmware uses 15 MB of host memory and firmware
request 1 MB size segments in QMI, whereas in mode-0 firmware uses 45 MB
of host memory and each segment is of 2 MB size. In mode-2 firmware
operates with reduced number of vdevs and peers.

This part is clear after reading the commit log.

But this part isn't. All I can see in the commit log is a vague comment
"and fill the proper pdev id in the request message" and nothing else.
Please provide a proper explanation for this change and I can then add
that to the commit log.

Hi Kalle,
In patch 701e48a43e15 ("ath11k: add packet log support for QCA6390") ,
both HTT_PPDU_STATS_CFG_PDEV_ID and pdev_mask were changed, but this 
pdev_mask calculation
is not valid for platforms which has multiple pdevs with 1 rxdma per 
pdev, as this is writing same value(i.e. 2) for all pdevs.
Hence fixed it to consider pdev_idx as well, to make it compatible for 
both single and multi pd cases.

I am worried about this array. It implies that _all_ hardware support
these modes but is that really the case? I would guess that these are
very much hardware and firmware specific values.

So because of that I would feel clearer to have num_vdevs and num_peers
in ath11k_hw_params, to make it clear that the values are hardware
specific. And then have fw_mem_mode, num_vdevs and num_peers in their
own struct within struct ath11k_hw_params, just like spectral has
grouped valued together.

Sorry for the delayed response. I will make num_vdevs and num_peers part 
of hw_params.
and post next version.
