cfg80211: Add a function to get the number of supported channels

2014-01-09T13:24:24+00:00

Add a utility function to get the number of channels supported by
the device, and update the places in the code that need this data.

cfg80211/mac80211: correct qos-map locking

2013-12-30T22:14:03+00:00

Since the RTNL can't always be held, use wdev/sdata locking for
the qos-map dereference in mac80211. This requires cfg80211 to
consistently lock it, which it was missing in one place.

cfg80211: Add support for QoS mapping

2013-12-19T15:29:22+00:00

This allows QoS mapping from external networks to be implemented as
defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise
DSCP ranges and exceptions for mapping frames to a specific UP over
Wi-Fi.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)
is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to
configure the local behavior either on the AP (based on local
configuration) or on a station (based on information received from the
AP).

nl80211/cfg80211: enable DFS for IBSS mode

2013-10-28T14:05:21+00:00

To use DFS in IBSS mode, userspace is required to react to radar events.
It can inform nl80211 that it is capable of doing so by adding a
NL80211_ATTR_HANDLE_DFS attribute when joining the IBSS.

This attribute is supplied to let the kernelspace know that the
userspace application can and will handle radar events, e.g. by
intiating channel switches to a valid channel. DFS channels may
only be used if this attribute is supplied and the driver supports
it. Driver support will be checked even if a channel without DFS
will be initially joined, as a DFS channel may be chosen later.

priority field to determine the WMM priority.

cfg80211/mac80211: get mandatory rates based on scan width

2013-07-16T06:58:07+00:00

Mandatory rates for 5 and 10 MHz are different from the rates used for
20 MHz in 2.4 GHz mode, as they use OFDM only.

cfg80211: remove some locked wrappers from sme API

2013-05-24T22:02:22+00:00

By making all the API functions require wdev locking we
can clean up the API a bit, getting rid of the locking
version of each function. This also decreases the size
of cfg80211 by a small amount.

cfg80211: vastly simplify locking

2013-05-24T22:02:15+00:00

Virtually all code paths in cfg80211 already (need to) hold
the RTNL. As such, there's little point in having another
four mutexes for various parts of the code, they just cause
lock ordering issues (and much of the time, the RTNL and a
few of the others need thus be held.)

Simplify all this by getting rid of the extra four mutexes
and just use the RTNL throughout. Only a few code changes
were needed to do this and we can get rid of a work struct
for bonus points.
