2019-06-24mwifiex: Don't abort on small, spec-compliant vendor IEsBrian Norris
Per the 802.11 specification, vendor IEs are (at minimum) only required to contain an OUI. A type field is also included in ieee80211.h (struct ieee80211_vendor_ie) but doesn't appear in the specification. The remaining fields (subtype, version) are a convention used in WMM headers. Thus, we should not reject vendor-specific IEs that have only the minimum length (3 bytes) -- we should skip over them (since we only want to match longer IEs, that match either WMM or WPA formats). We can reject elements that don't have the minimum-required 3 byte OUI. While we're at it, move the non-standard subtype and version fields into the WMM structs, to avoid this confusion in the future about generic "vendor header" attributes.

2018-05-29mwifiex: skip sending GT_REKEY_OFFLOAD_CFG if firmware has no supportGanapathi Bhat
If firmware does not support embedded supplicant, then it in turn will not support GT rekey offloading. If this is the case, then driver must not advertise WOWLAN flags related to GTK rekey and it must also skip sending the GT_REKEY_OFFLOAD_CFG command.

2018-03-13mwifiex: get_channel from firmwareGanapathi Bhat
At present driver gets chan_type by referring to IEEE80211_HT_PARAM_CHA_SEC_OFFSET, in ASSOC response. Sometimes AP shows IEEE80211_HT_PARAM_CHA_SEC_OFFSET as above/below in assoc response, even if the association is done on HT20 channel only. So, it will be accurate to get econdary channel offset from firmware.

2018-01-08mwifiex: debugfs: trigger device dump for usb interfaceXinming Hu
This patch extend device_dump debugfs function to make it works for usb interface. For command timeouts, USB firmware will automatically emit firmware dump events, so we don't implement device_dump(). For user-initiated dumps, we trigger it by issue firmware dump event command to firmware, as there is no command response, do not start 10s timer.

2016-07-05mwifiex: add get_antenna support for cfg80211Shengzhen Li
Since commit de3bb771f471 ("cfg80211: add more warnings for inconsistent ops") the wireless core warns if a driver implements a cfg80211 callback but doesn't implements the inverse operation. The mwifiex driver defines a .set_antenna handler but not a .get_antenna so this not only makes the core to print a warning when creating a new wiphy but also the antenna isn't reported to user-space apps such as iw. This patch queries the antenna to the firmware so is properly reported to user-space. With this patch, the wireless core does not warn anymore and: $ iw phy phy0 info | grep Antennas Available Antennas: TX 0x3 RX 0x3 Configured Antennas: TX 0x3 RX 0x3 Signed-off-by: Shengzhen Li <szli@marvell.com> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> [javier: expand the commit message] Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Tested-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-01-29mwifiex: firmware download enhancementschunfan chen
Same chip is being used by WLAN as well as bluetooth drivers. Each driver needs to check during initialisation if firmware is already active or it needs to be freshly downloaded. If one driver has started downloading the firmware, other finds the winner flag as false. mwifiex_check_fw_status() checks firmware status and also check if WLAN is the winner for firmware downloading. Once we detect that other interface is downloading the firmware, we call this routine again with max poll count to wait until firmware is ready. This patch splits the routine to avoid checking winner status unnecessarily multiple times and ensures that correct messages are displayed to user. Firmware status poll count is also increased to 150.
