cfg80211: Add support to update connection parameters

2016-10-27T14:03:28+00:00

Add functionality to update the connection parameters when in connected state, so that driver/firmware uses the updated parameters for subsequent roaming. This is for drivers that support internal BSS selection and roaming. The new command does not change the current association state, i.e., it can be used to update IE contents for future (re)associations without causing an immediate disassociation or reassociation with the current BSS. This commit implements the required functionality for updating IEs for (Re)Association Request frame only. Other parameters can be added in future when required.

cfg80211: configure multicast to unicast for AP interfaces

2016-10-27T14:03:27+00:00

Add the ability to configure if an AP (and associated VLANs) will do multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames (possibly within 802.1Q). If enabled, such frames are to be sent to each station separately, with the DA replaced by their own MAC address rather than the group address. Note that this may break certain expectations of the receiver, such as the ability to drop unicast IP packets received within multicast L2 frames, or the ability to not send ICMP destination unreachable messages for packets received in L2 multicast (which is required, but the receiver can't tell the difference if this new option is enabled.) This also doesn't implement the 802.11 DMS (directed multicast service). Signed-off-by: Michael Braun [fix disabling, add better documentation & commit message] Signed-off-by: Johannes Berg

cfg80211: allow the user space to change current NAN configuration

2016-09-30T11:21:28+00:00

Some NAN configuration paramaters may change during the operation of the NAN device. For example, a user may want to update master preference value when the device gets plugged/unplugged to the power. Add API that allows to do so.

cfg80211: add add_nan_func / del_nan_func

2016-09-30T11:21:23+00:00

A NAN function can be either publish, subscribe or follow up. Make all the necessary verifications and just pass the request to the driver. Allow the user space application that starts NAN to forbid any other socket to add or remove functions.

cfg80211: add start / stop NAN commands

2016-09-30T11:21:14+00:00

This allows user space to start/stop NAN interface. A NAN interface is like P2P device in a few aspects: it doesn't have a netdev associated to it. Add the new interface type and prevent operations that can't be executed on NAN interface like scan. Define several attributes that may be configured by user space when starting NAN functionality (master preference and dual band operation) Signed-off-by: Andrei Otcheretianski Signed-off-by: Emmanuel Grumbach Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

nl80211: support beacon report scanning

2016-07-06T12:51:31+00:00

Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

cfg80211: remove enum ieee80211_band

2016-04-12T13:56:15+00:00

This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg

cfg80211: Add option to specify previous BSSID for Connect command

2016-04-06T11:18:21+00:00

This extends NL80211_CMD_CONNECT to allow the NL80211_ATTR_PREV_BSSID attribute to be used similarly to way this was already allowed with NL80211_CMD_ASSOCIATE. This allows user space to request reassociation (instead of association) when already connected to an AP. This provides an option to reassociate within an ESS without having to disconnect and associate with the AP. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg

cfg80211: Add support for aborting an ongoing scan

2015-12-04T13:43:32+00:00

Implement new functionality for aborting an ongoing scan. Add NL80211_CMD_ABORT_SCAN to the nl80211 interface. After aborting the scan, driver shall provide the scan status by calling cfg80211_scan_done().

cfg80211: add complete data to station add/change tracing

2015-12-04T13:43:32+00:00

Complete the tracepoint with the missing data - it's not printed by default (a lot of it is dynamic arrays) but will be recorded and be available during post-processing. Signed-off-by: Johannes Berg
