cfg80211: validate channel settings across interfaces

2009-08-14T13:13:42+00:00

Currently, there's a problem that affects regulatory
enforcement and connection stability, in that it is
possible to switch the channel while connected to a
network or joined to an IBSS.

The problem comes from the fact that we only validate
the channel against the current interface's type, not
against any other interface. Thus, you have any type
of interface up, additionally bring up a monitor mode
interface and switch the channel on the monitor. This
will obviously also switch the channel on the other
interface.

The problem now is that if you do that while sending
beacons for IBSS mode, you can switch to a disabled
channel or a channel that doesn't allow beaconing.
Combined with a managed mode interface connected to
an AP instead of an IBSS interface, you can easily
break the connection that way.

To fix this, this patch validates any channel change
with all available interfaces, and disallows such
changes on secondary interfaces if another interface
is connected to an AP or joined to an IBSS.

cfg80211: managed mode wext compatibility

2009-07-10T19:01:51+00:00

This adds code to make it possible to use the cfg80211
connect() API with wireless extensions, and because the
previous patch added emulation of that API with auth()
and assoc(), by extension also supports wext on that.
At the same time, removes code from mac80211 for wext,
but doesn't yet clean up mac80211's mlme code more.

cfg80211: connect/disconnect API

2009-07-10T19:01:51+00:00

This patch introduces the cfg80211 connect/disconnect API.
The goal here is to run the AUTH and ASSOC steps in one call.
This is needed for some fullmac cards that run both steps
directly from the target, after the host driver sends a
connect command.

Additionally, all the new crypto parameters for connect()
are now also valid for associate() -- although associate
requires the IEs to be used, the information can be useful
for drivers and should be given.

mac80211/cfg80211: move wiphy specific debugfs entries to cfg80211

2009-05-20T18:46:23+00:00

This moves the cfg80211 specific stuff to new cfg80211 debugfs
entries. Non-mac80211 will also get these entries now. There were
only 4 which we take:

rts_threshold
fragmentation_threshold
short_retry_limit
long_retry_limit

cfg80211/nl80211: add IBSS API

2009-04-22T20:57:17+00:00

This adds IBSS API along with (preliminary) wext handlers.
The wext handlers can only do IBSS so you need to call them
from your own wext handlers if the mode is IBSS.

The nl80211 API requires
 * an SSID
 * a channel (frequency) for the case that a new IBSS
   has to be created

It optionally supports
 * a flag to fix the channel
 * a fixed BSSID

The cfg80211 code also takes care to leave the IBSS before
the netdev is set down. If wireless extensions are used, it
also caches values when the interface is down and instructs
the driver to join when the interface is set up.

nl80211: Event notifications for MLME events

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

Add new nl80211 event notifications (and a new multicast group, "mlme")
for informing user space about received and processed Authentication,
(Re)Association Response, Deauthentication, and Disassociation frames in
station and IBSS modes (i.e., MLME SAP interface primitives
MLME-AUTHENTICATE.confirm, MLME-ASSOCIATE.confirm,
MLME-REASSOCIATE.confirm, MLME-DEAUTHENTICATE.indicate, and
MLME-DISASSOCIATE.indication). The event data is encapsulated as the 802.11
management frame since we already have the frame in that format and it
includes all the needed information.

This is the initial step in providing MLME SAP interface for
authentication and association with nl80211. In other words, kernel code
will act as the MLME and a user space application can control it as the
SME.

cfg80211/nl80211: remove usage of CONFIG_NL80211

2009-03-28T00:12:42+00:00

The scan capability added to cfg80211/nl80211 introduced a
dependency on nl80211 by cfg80211. We can thus no longer have
just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
calls nl80211_send_scan_aborted() or nl80211_send_scan_done().

Now we remove the option for user to select nl80211. It will always
be compiled if user selects cfg80211.

cfg80211/nl80211: scanning (and mac80211 update to use it)

2009-02-13T18:45:49+00:00

This patch adds basic scan capability to cfg80211/nl80211 and
changes mac80211 to use it. The BSS list that cfg80211 maintains
is made driver-accessible with a private area in each BSS struct,
but mac80211 doesn't yet use it. That's another large project.
