cfg80211: Allow non-zero indexes for device specific pair-wise ciphers

2011-01-28T20:44:27+00:00

Some vendor specific cipher suites require non-zero key indexes for pairwise
keys, but as of currently, the cfg80211 does not allow it.

As validating they cipher parameters for vendor specific cipher suites is the
job of the driver or hardware/firmware, change the cfg80211 to allow also
non-zero pairwise key indexes for vendor specific ciphers.

cfg80211: Extend channel to frequency mapping for 802.11j

2011-01-21T20:34:17+00:00

Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.

This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.

The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
The drivers have been compile-tested only.

cfg80211/nl80211: separate unicast/multicast default TX keys

2010-12-13T20:23:28+00:00

Allow userspace to specify that a given key
is default only for unicast and/or multicast
transmissions. Only WEP keys are for both,
WPA/RSN keys set here are GTKs for multicast
only. For more future flexibility, allow to
specify all combiations.

Wireless extensions can only set both so use
nl80211; WEP keys (connect keys) must be set
as default for both (but 802.1X WEP is still
possible).

cfg80211/mac80211: add mesh join/leave commands

2010-12-06T21:01:29+00:00

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.

Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.

We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.

In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

net/wireless: Use pr_ and netdev_

2010-11-24T21:19:33+00:00

No change in output for pr_ prefixes.
netdev_ output is different, arguably improved.

cfg80211/mac80211: allow per-station GTKs

2010-10-06T20:30:40+00:00

This adds API to allow adding per-station GTKs,
updates mac80211 to support it, and also allows
drivers to remove a key from hwaccel again when
this may be necessary due to multiple GTKs.

cfg80211/nl80211: introduce p2p device types

2010-09-16T19:46:06+00:00

This adds P2P-STA and P2P-GO as device types so
we can distinguish between those and normal STA
or AP (respectively) type interfaces.

cfg80211: allow vendor specific cipher suites

2010-08-27T17:27:07+00:00

cfg80211 currently rejects all cipher suites it
doesn't know about for key length checking
purposes. This can lead to inconsistencies when
a driver advertises an algorithm that cfg80211
doesn't know about. Remove this rejection so
drivers can specify any algorithm they like.

cfg80211/mac80211: extensible frame processing

2010-08-24T20:27:56+00:00

Allow userspace to register for more than just
action frames by giving the frame subtype, and
make it possible to use this in various modes
as well.

With some tweaks and some added functionality
this will, in the future, also be usable in AP
mode and be able to replace the cooked monitor
interface currently used in that case.

cfg80211: mark ieee80211_hdrlen const

2010-08-24T20:27:54+00:00

This function analyses only its single, value-passed
argument, and has no side effects. Thus it can be
const, which makes mac80211 smaller, for example:

   text	   data	    bss	    dec	    hex	filename
 362518	  16720	    884	 380122	  5ccda	mac80211.ko (before)
 362358	  16720	    884	 379962	  5cc3a	mac80211.ko (after)

a 160 byte saving in text size, and an optimisation
because the function won't be called as often.
