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)

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.

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: allow mgmt_frame_register callback to sleep

2015-07-17T13:38:26+00:00

This callback is currently not allowed to sleep, which makes it more
difficult to implement proper driver methods in mac80211 than it has
to be. Instead of doing asynchronous work here in mac80211, make it
possible for the callback to sleep by doing some asynchronous work
in cfg80211. This also enables improvements to other drivers, like
ath6kl, that would like to sleep in this callback.

While at it, also fix the code to call the driver on the implicit
unregistration when an interface is removed, and do that also when
a P2P-Device wdev is destroyed (otherwise we leak the structs.)

cfg80211: pass name_assign_type to rdev_add_virtual_intf()

2015-03-30T08:36:17+00:00

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

Similar functionality was introduced for the rtnetlink core in
commit 5517750f058e ("net: rtnetlink - make create_link take name_assign_type")

cfg80211: introduce TDLS channel switch commands

2014-11-19T17:45:12+00:00

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.

Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

cfg80211: 802.11p OCB mode handling

2014-11-04T12:18:17+00:00

This patch adds new iface type (NL80211_IFTYPE_OCB) representing
the OCB (Outside the Context of a BSS) mode.
When establishing a connection to the network a cfg80211_join_ocb
function is called (particular nl80211_command is added as well).
A mandatory parameters during the ocb_join operation are 'center
frequency' and 'channel width (5/10 MHz)'.

Changes done in mac80211 are minimal possible required to avoid
many warnings (warning: enumeration value 'NL80211_IFTYPE_OCB'
not handled in switch) during compilation. Full functionality
(where needed) is added in the following patch.
