nl80211: add/fix mesh docs

2011-01-10T20:40:52+00:00

Some mesh attribute/command docs are missing or
have errors in the name so they don't match, fix
all of them.

mac80211: Let userspace enable and configure vendor specific path selection.

2010-12-20T19:46:57+00:00

Userspace will now be allowed to toggle between the default path
selection algorithm (HWMP, implemented in the kernel), and a vendor
specific alternative.  Also in the same patch, allow userspace to add
information elements to mesh beacons.  This is accordance with the
Extensible Path Selection Framework specified in version 7.0 of the
802.11s draft.

mac80211: Rename mesh_params to mesh_config to prepare for mesh_setup

2010-12-20T19:46:57+00:00

Mesh parameters can be to setup a mesh or to configure it.
This patch renames the ambiguous name mesh_params to mesh_config
in preparation for mesh_setup.

nl80211: Add notification for dropped Deauth/Disassoc

2010-12-16T20:22:30+00:00

Add a new notification to indicate that a received, unprotected
Deauthentication or Disassociation frame was dropped due to
management frame protection being in use. This notification is
needed to allow user space (e.g., wpa_supplicant) to implement
SA Query procedure to recover from association state mismatch
between an AP and STA.

This is needed to avoid getting stuck in non-working state when MFP
(IEEE 802.11w) is used and a protected Deauthentication or
Disassociation frame is dropped for any reason. After that, the
station would silently discard any unprotected Deauthentication or
Disassociation frame that could be indicating that the AP does not
have association for the STA (when the Reason Code would be 6 or 7).
IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism.

nl80211: advertise maximum remain-on-channel duration

2010-12-15T22:03:56+00:00

With the upcoming hardware offload implementation,
some devices will have a different maximum duration
for the remain-on-channel command. Advertise the
maximum duration in mac80211, and make mac80211 set
it.

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: Add new BSS attribute ht_opmode

2010-12-08T20:38:43+00:00

Add a new BSS attribute to allow hostapd to set the current HT opmode.
Otherwise drivers won't be able to set up protection for HT rates in
AP mode.

nl80211/mac80211: Report signal average

2010-12-07T21:09:12+00:00

Extend nl80211 to report an exponential weighted moving average (EWMA) of the
signal value. Since the signal value usually fluctuates between different
packets, an average can be more useful than the value of the last packet.

This uses the recently added generic EWMA library function.

v2:	fix ABI breakage and change factor to be a power of 2.

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.
