mac80211: correct header length calculation

2015-01-23T09:52:48+00:00

HT Control field may also be present in management frames, as defined
in 8.2.4.1.10 of 802.11-2012. Account for this in calculation of header
length.

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.

cfg80211: clear connect keys when freeing them

2014-09-11T10:07:18+00:00

When freeing the connect keys, clear the memory to avoid
having the key material stick around in memory "forever".

cfg80211: add Intel Mobile Communications copyright

2014-09-05T11:52:06+00:00

Our legal structure changed at some point (see wikipedia), but
we forgot to immediately switch over to the new copyright
notice.

For files that we have modified in the time since the change,
add the proper copyright notice now.

cfg80211: implement cfg80211_get_station cfg80211 API

2014-05-21T07:15:17+00:00

Implement and export the new cfg80211_get_station() API.
This utility can be used by other kernel modules to obtain
detailed information about a given wireless station.

It will be in particular useful to batman-adv which will
implement a wireless rate based metric.

cfg80211: constify more pointers in the cfg80211 API

2014-05-19T15:53:16+00:00

This also propagates through the drivers.

The orinoco driver uses the cfg80211 API structs for internal
bookkeeping, and so needs a (void *) cast that removes the
const - but that's OK because it allocates those pointers.

cfg80211: allow restricting supported dfs regions

2014-05-13T13:50:06+00:00

At the moment, the ath9k/ath10k DFS module only supports detecting ETSI
radar patterns.
Add a bitmap in the interface combinations, indicating which DFS regions
are supported by the detector. If unset, support for all regions is
assumed.

cfg80211: export interface stopping function

2014-05-06T13:16:34+00:00

This exports a new cfg80211_stop_iface() function.

This is intended for driver internal interface
combination management and channel switching.

Due to locking issues (it re-enters driver) the
call is asynchronous and uses cfg80211 event
list/worker.

cfg80211: change wiphy_to_dev function name

2014-04-25T15:33:04+00:00

Name wiphy_to_rdev is more accurate to describe what the function
does, i.e., return a pointer pointing to struct
cfg80211_registered_device.

cfg80211: allow drivers to iterate over matching combinations

2014-04-25T15:08:14+00:00

The patch splits cfg80211_check_combinations()
into an iterator function and a simple iteration
user.

This makes it possible for drivers to asses how
many channels can use given iftype setup. This in
turn can be used for future
multi-interface/multi-channel channel switching.
