cfg80211: fix NAN bands definition

2017-02-09T14:17:30Z

The nl80211_nan_dual_band_conf enumeration doesn't make much sense. The default value is assigned to a bit, which makes it weird if the default bit and other bits are set at the same time. To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy configuration to let the drivers define which bands are supported. This is exposed to the userspace, which then can make a decision on which band(s) to use. Additionally, rename all "dual_band" elements to "bands", to make things clearer.

cfg80211: Pass new RSSI level in CQM RSSI notification

2017-02-08T09:43:40Z

Update the drivers to pass the RSSI level as a cfg80211_cqm_rssi_notify parameter and pass this value to userspace in a new nl80211 attribute. This helps both userspace and also helps in the implementation of the multiple RSSI thresholds CQM mechanism. Note for marvell/mwifiex I pass 0 for the RSSI value because the new RSSI value is not available to the driver at the time of the cfg80211_cqm_rssi_notify call, but the driver queries the new value immediately after that, so it is actually available just a moment later if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment. Without this, the new cfg80211 code (patch 3) will call .get_station which will send a duplicate HostCmd_CMD_RSSI_INFO command to the hardware.

cfg80211: Specify the reason for connect timeout

2017-01-13T08:46:18Z

This enhances the connect timeout API to also carry the reason for the timeout. These reason codes for the connect time out are represented by enum nl80211_timeout_reason and are passed to user space through a new attribute NL80211_ATTR_TIMEOUT_REASON (u32).

cfg80211: Add support to sched scan to report better BSSs

2017-01-13T08:40:41Z

Enhance sched scan to support option of finding a better BSS while in connected state. Firmware scans the medium and reports when it finds a known BSS which has better RSSI than the current connected BSS. New attributes to specify the relative RSSI (compared to the current BSS) are added to the sched scan to implement this.

cfg80211: Add support for randomizing TA of Public Action frames

2017-01-13T08:39:47Z

Add support to use a random local address (Address 2 = TA in transmit and the same address in receive functionality) for Public Action frames in order to improve privacy of WLAN clients. Applications fill the random transmit address in the frame buffer in the NL80211_CMD_FRAME command. This can be used only with the drivers that indicate support for random local address by setting the new NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features. The driver needs to configure receive behavior to accept frames to the specified random address during the time the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is not used.

cfg80211: consider VHT opmode on station update

2017-01-11T15:34:25Z

Currently, this attribute is only fetched on station addition, but not on station change. Since this info is only present in the assoc request, with full station state support in the driver it cannot be present when the station is added. Thus, add support for changing the VHT opmode on station update if done before (or while) the station is marked as associated. After this, ignore it, since it used to be ignored.

cfg80211: NL80211_ATTR_SOCKET_OWNER support for CMD_CONNECT

2017-01-09T12:08:47Z

Disconnect or deauthenticate when the owning socket is closed if this flag is supplied to CMD_CONNECT or CMD_ASSOCIATE. This may be used to ensure userspace daemon doesn't leave an unmanaged connection behind. In some situations it would be possible to account for that, to some degree, in the deamon restart code or in the up/down scripts without the use of this attribute. But there will be systems where the daemon can go away for varying periods without a warning due to local resource management. Signed-off-by: Andrew Zaborowski Signed-off-by: Johannes Berg

nl80211: Use different attrs for BSSID and random MAC addr in scan req

2016-12-09T11:47:19Z

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned and the random MAC address to be used when privacy is enabled. When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d39177 ("cfg80211: Allow a scan request for a specific BSSID").
