wil6210: check null pointer in _wil_cfg80211_merge_extra_ies

2019-02-28T09:25:09+00:00

ies1 or ies2 might be null when code inside
_wil_cfg80211_merge_extra_ies access them.
Add explicit check for null and make sure ies1/ies2 are not
accessed in such a case.

spos might be null and be accessed inside
_wil_cfg80211_merge_extra_ies.
Add explicit check for null in the while condition statement
and make sure spos is not accessed in such a case.

wil6210: ignore HALP ICR if already handled

2019-02-28T09:24:59+00:00

HALP ICR is set as long as the FW should stay awake.
To prevent its multiple handling the driver masks this IRQ bit.
However, if there is a different MISC ICR before the driver clears
this bit, there is a risk of race condition between HALP mask and
unmask. This race leads to HALP timeout, in case it is mistakenly
masked.
Add an atomic flag to indicate if HALP ICR should be handled.

wil6210: fix invalid sta statistics update

2019-02-28T09:24:50+00:00

Upon status ring handling, in case there are both unicast and
multicast (cid == max) status messages to handle, wrong sta statistics
might get updated.
Fix this by setting stats to NULL upon invalid cid
(e.g. == max_assoc_sta).

wil6210: accessing 802.3 addresses via utility functions

wil6210: support up to 20 stations in AP mode

2019-02-28T09:24:29+00:00

New FW added support for upto 20 clients in AP mode. Change the driver
to support this as well. FW reports it's max supported associations in
WMI_READY_EVENT. Some WMI commands/events use cidxtid field which is
limited to 16 cids. Use new cid/tid fields instead.

For Rx packets cid from rx descriptor is limited to 3 bits (0..7),
to find the real cid, compare transmitter address with the stored
stations mac address in the driver sta array.

EDMA FW still supports 8 stations. Extending the support to 20
stations will come later.

wil6210: add option to drop Tx packets when Tx ring is full

2019-02-28T09:24:19+00:00

In AP mode with multiple clients, driver stops net queue
(netif_tx_stop_queue) upon first ring (serving specific client)
becoming full. This can have negative effect on transmission to
other clients which may still have room in their corresponding rings.

Implement new policy in which stop/wake net queue are not used. In
case there is no room in the ring for a transmitted packet, drop the
packet.

New policy can be helpful to debug performance issues, to guarantee
maximum utilization of net queues.
New policy is disabled by default and can be enabled by debugfs:
echo 1 > drop_if_ring_full

wil6210: remove rtap_include_phy_info module param

2019-02-28T09:24:09+00:00

Due to a HW issue in PHY info collection rtap_include_phy_info is not
in use, hence can be removed.

ath10k: Fill rx duration for each peer in fw_stats for WCN3990

2019-02-28T08:48:19+00:00

Currently, rx_duration for each peer is not getting populated in
fw_stats debugfs entry for WCN3990.

WCN3990 firmware sends rx duration for each peer as part of
peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats,
firmware expects host to send fw_stats_req_mask with flag
WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD.

Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in
WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in
WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer
in fw_stats debugfs entry.

Currently the driver handles 32-bit rx_duration, but the rx_duration
for WCN3990 can be upto 63 bit. The firmware sends rx_duration split
into two 32-bit fields, with the upper 32-bits being valid only if its
MSB is set. This change handles the 63-bit rx_duration obtained from
WCN3990 and maintain the backward compatibility.

To get the rx_duration of each connected peer :
cat /sys/kernel/debug/ieee80211/phyX/ath10k/fw_stats

ath10k: Fix the wrong calculation ht_idx and idx of rate table for tx_stats

2019-02-28T08:46:26+00:00

ht_idx (ht rate index) and idx (rate table index) are calculated based on
mcs index. This mcs index used in the above calculation should be 0-9 for
getting the correct ht_idx and idx.

Currently the mcs index used for the above calculations is mcs index which
can be 0-31 (in case of HT), leading to incorrect rate index and ht index values.

Fix the issue by obtaining mcs value from the ratecode reported by firmware
and use it for calculating ht_idx and idx (rate-table index).

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1
