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.

{nl,mac,cfg}80211: Allow user to configure basic rates for mesh

2013-06-11T12:24:36+00:00

Currently mesh uses mandatory rates as the default basic rates. Allow basic
rates to be configured during mesh join. Basic rates are applied only if
channel is also provided with mesh join command.

{nl,cfg}80211: make peer link expiration time configurable

2013-06-11T12:16:29+00:00

If a STA has a peer that it hasn't seen any tx activity
from for a certain length of time, the peer link is
expired. This means the inactive STA is removed from the
list of peers and that STA is not considered a peer again
unless it re-peers.  Previously, this inactivity time was
always 30 minutes.  Now, add it to the mesh configuration
and allow it to be configured.  Retain 30 minutes as a
default value.

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.

cfg80211: Userspace may inform kernel of mesh auth method.

2013-05-16T20:39:43+00:00

Authentication takes place in userspace, but the beacon is
generated in the kernel.  Allow userspace to inform the
kernel of the authentication method so the appropriate
mesh config IE can be set prior to beacon generation when
joining the MBSS.

nl80211: explicit userspace MPM

2013-03-06T15:36:11+00:00

Secure mesh had the implicit requirement that the Mesh
Peering Management entity be in userspace.  However
userspace might want to implement an open MPM as well, so
specify a mesh setup parameter to indicate this.

cfg80211: move exported event functions into nl80211

2013-03-06T15:35:46+00:00

This is the sort of thing gcc's LTO could do, but since
we don't have that yet we can also do it manually. The
advantage is reduced code, both source and binary, e.g.
on x86-64

   text	   data	    bss	    dec	    hex	filename
 442825	  56230	    776	 499831	  7a077	cfg80211.ko (before)
 441585	  56230	    776	 498591	  79b9f	cfg80211.ko (after)

a reduction of ~1k.

But in order to not complicate the code move only those
functions that are simple wrappers, not those that have
functionality of their own.

{cfg,nl}80211: mesh power mode primitives and userspace access

2013-01-16T21:48:04+00:00

Add the nl80211_mesh_power_mode enumeration which holds possible
values for the mesh power mode. These modes are unknown, active,
light sleep and deep sleep.

Add power_mode entry to the mesh config structure to hold the
user-configured default mesh power mode. This value will be used
for new peer links.

Add the dot11MeshAwakeWindowDuration value to the mesh config.
The awake window is a duration in TU describing how long the STA
will stay awake after transmitting its beacon in PS mode.

Add access routines to:
 - get/set local link-specific power mode (STA)
 - get remote STA's link-specific power mode (STA)
 - get remote STA's non-peer power mode (STA)
 - get/set default mesh power mode (mesh config)
 - get/set mesh awake window duration (mesh config)

All config changes may be done at mesh runtime and take effect
immediately.

{cfg,nl,mac}80211: set beacon interval and DTIM period on mesh join

2013-01-16T21:44:04+00:00

Move the default mesh beacon interval and DTIM period to cfg80211
and make them accessible to nl80211. This enables setting both
values when joining an MBSS.

Previously the DTIM parameter was not set by mac80211 so the
driver's default value was used.

cfg80211: fix channel error on mesh join

Fix an error on mesh join when no channel has been
explicitly set beforehand.

Also remove a double semicolon.
