qtnfmac: fix error handling in control path

2019-01-26T08:20:39+00:00

[ Upstream commit 1066bd193d681bda0fbacda9df351241a5ee04d9 ] This patch fixes the following warnings: - smatch drivers/net/wireless/quantenna/qtnfmac/commands.c:132 qtnf_cmd_send_with_reply() warn: variable dereferenced before check 'resp' (see line 117) drivers/net/wireless/quantenna/qtnfmac/commands.c:716 qtnf_cmd_get_sta_info() error: uninitialized symbol 'var_resp_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1668 qtnf_cmd_get_mac_info() error: uninitialized symbol 'var_data_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1697 qtnf_cmd_get_hw_info() error: uninitialized symbol 'info_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1753 qtnf_cmd_band_info_get() error: uninitialized symbol 'info_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1782 qtnf_cmd_send_get_phy_params() error: uninitialized symbol 'response_size'. drivers/net/wireless/quantenna/qtnfmac/commands.c:2438 qtnf_cmd_get_chan_stats() error: uninitialized symbol 'var_data_len'. - gcc-8.2.1 drivers/net/wireless/quantenna/qtnfmac/commands.c: In function 'qtnf_cmd_send_with_reply': drivers/net/wireless/quantenna/qtnfmac/commands.c:133:54: error: 'resp' may be used uninitialized in this function [-Werror=maybe-uninitialized] Reported-by: Dan Carpenter Reported-by: Arnd Bergmann Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo Signed-off-by: Sasha Levin

Fix checkpatch warning: use preferred 'help' option in Kconfig. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: implement dump_station support for STA mode

2018-10-05T11:01:44+00:00

Current implementation of dump_station cfg80211 callback supports AP mode only. Add support for STA mode as well: by default in STA mode this callback is supposed to return AP on managed interface. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: drop redundant data copy in control path

2018-10-05T11:01:41+00:00

Command responses and events from the firmware are copied twice in control path: at first in shm core (qtnf_shm_handle_new_data) and then in pcie bus drivers (qtnf_pcie_control_rx_callback). There is no need to copy this data twice, it can be done only once in rx callbacks. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: add support for scan dwell time configuration

2018-10-05T11:01:37+00:00

Firmware supports scan dwell time tuning for various types of scans. Enable support for this feature: - advertise capability to configure channel dwell time to host - pass scan dwell parameters to wireless card in scan request Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: add support for scan flush

2018-10-05T11:01:33+00:00

Notify firmware to flush cache before scanning when needed. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: drop error reports for out-of-bounds key indexes

2018-10-05T11:01:29+00:00

On disconnect wireless core attempts to remove all the supported keys. Following cfg80211_ops conventions, firmware returns -ENOENT code for the out-of-bound key indexes. This is a normal behavior, so no need to report errors for this case. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: inform wireless core about supported extended capabilities

2018-10-05T11:01:24+00:00

Driver retrieves information about supported extended capabilities from wireless card. However this information is not propagated further to Linux wireless core. Fix this by setting extended capabilities fields of wiphy structure. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo
