mac80211: Update mesh config IE to 11s draft 3.02

2009-08-28T18:40:24+00:00

The mesh config information element has changed significantly since draft 1.08
This patch brings it up to date.

Thanks to Sam Leffler and Rui Paulo for identifying this.

wireless: define AKM suites

2009-07-10T19:01:50+00:00

We'll need these values for some drivers using connect API
and for wext compat code, so let's define them.

cfg80211: use key size constants

2009-06-03T18:05:10+00:00

Instead of hardcoding the key length for validation, use the
constants Zhu Yi recently added and add one for AES_CMAC too.

wireless: move some utility functions from mac80211 to cfg80211

2009-05-22T18:06:02+00:00

The patch moves some utility functions from mac80211 to cfg80211.
Because these functions are doing generic 802.11 operations so they
are not mac80211 specific. The moving allows some fullmac drivers
to be also benefit from these utility functions.

mac80211: Robust Action frame categories for MFP

2009-05-11T19:24:07+00:00

IEEE 802.11w/D9.0 introduces a mechanism for Action field Category
values to be used to select which Action frames are Robust. Public and
Vendor-specific categories are marked as not Robust in IEEE 802.11w;
HT will be marked not Robust in IEEE 802.11n. A new Vendor-specific
Protected category is allocated for Robust vendor-specific Action
frames. Another new category, Protected Dual of Action, is introduced
for protecting some existing Public Action frames (e.g., IEEE 802.11y
protected enablement).

mac80211: validate TIM IE length (redux)

2009-04-22T20:57:18+00:00

The TIM IE must not be shorter than 4 bytes, so verify that
when parsing it and use the proper type. To ease that adjust
struct ieee80211_tim_ie to have a virtual bitmap of size
at least 1.

Also check that the TIM IE is actually present before trying
to parse it!

Because other people may need the function, make it a static
inline in ieee80211.h.

(The original "mac80211: validate TIM IE length" was a minimal fix for
2.6.30.  This purports to be the full, correct fix. -- JWL)

mac80211: disable powersave if pm_qos asks for low latency

2009-04-22T20:57:16+00:00

When an application asks for a latency lower than the beacon interval
there's nothing we can do -- we need to stay awake and not have the
AP buffer frames for us. Add code to automatically calculate this
constraint in mac80211 so drivers need not concern themselves with it.

nl80211: Add MLME primitives to support external SME

2009-03-28T00:13:02+00:00

This patch adds new nl80211 commands to allow user space to request
authentication and association (and also deauthentication and
disassociation). The commands are structured to allow separate
authentication and association steps, i.e., the interface between
kernel and user space is similar to the MLME SAP interface in IEEE
802.11 standard and an user space application takes the role of the
SME.

The patch introduces MLME-AUTHENTICATE.request,
MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and
MLME-DISASSOCIATE.request primitives. The authentication and
association commands request the actual operations in two steps
(assuming the driver supports this; if not, separate authentication
step is skipped; this could end up being a separate "connect"
command).

The initial implementation for mac80211 uses the current
net/mac80211/mlme.c for actual sending and processing of management
frames and the new nl80211 commands will just stop the current state
machine from moving automatically from authentication to association.
Future cleanup may move more of the MLME operations into cfg80211.

The goal of this design is to provide more control of authentication and
association process to user space without having to move the full MLME
implementation. This should be enough to allow IEEE 802.11r FT protocol
and 802.11s SAE authentication to be implemented. Obviously, this will
also bring the extra benefit of not having to use WEXT for association
requests with mac80211. An example implementation of a user space SME
using the new nl80211 commands is available for wpa_supplicant.

This patch is enough to get IEEE 802.11r FT protocol working with
over-the-air mechanism (over-the-DS will need additional MLME
primitives for handling the FT Action frames).
