nl80211: Add RSC configuration for new keys

2009-05-13T19:44:39+00:00

When setting a key with NL80211_CMD_NEW_KEY, we should allow the key
sequence number (RSC) to be set in order to allow replay protection to
work correctly for group keys. This patch documents this use for
nl80211 and adds the couple of missing pieces in nl80211/cfg80211 and
mac80211 to support this. In addition, WEXT SIOCSIWENCODEEXT compat
processing in cfg80211 is extended to handle the RSC (this was already
specified in WEXT, but just not implemented in cfg80211/mac80211).

nl80211: Add IEEE 802.1X PAE control for station mode

2009-05-13T19:44:37+00:00

Add a new NL80211_ATTR_CONTROL_PORT flag for NL80211_CMD_ASSOCIATE to
allow user space to indicate that it will control the IEEE 802.1X port
in station mode. Previously, mac80211 was always marking the port
authorized in station mode. This was enough when drop_unencrypted flag
was set. However, drop_unencrypted can currently be controlled only
with WEXT and the current nl80211 design does not allow fully secure
configuration. Fix this by providing a mechanism for user space to
control the IEEE 802.1X port in station mode (i.e., do the same that
we are already doing in AP mode).

nl80211: improve station flags handling

2009-05-13T19:44:35+00:00

It is currently not possible to modify station flags, but that
capability would be very useful. This patch introduces a new
nl80211 attribute that contains a set/mask for station flags,
and updates the internal API (and mac80211) to mirror that.

The new attribute is parsed before falling back to the old so
that userspace can specify both (if it can) to work on all
kernels.

nl80211 : Add support for configuring MFP

2009-05-11T19:23:54+00:00

NL80211_CMD_ASSOCIATE request must be able to indicate whether
management frame protection (IEEE 802.11w) is being used. mac80211 was
able to use MFP in client mode only with WEXT, but the new
NL80211_ATTR_USE_MFP attribute will allow this to be done with
nl80211, too.

Since we are currently using nl80211 for MFP only with drivers that
use user space SME, only MFP disabled and required values are
used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can
be extended with MFP optional in the future, if that is needed with
some drivers (e.g., if the RSN IE is generated by the driver).

nl80211: Add event for authentication/association timeout

2009-04-22T20:57:21+00:00

SME needs to be notified when the authentication or association
attempt times out and MLME has stopped processing in order to allow
the SME to decide what to do next.

nl80211: allow configuring IBSS beacon interval

2009-04-22T20:57:20+00:00

Make the JOIN_IBSS command look at the beacon interval
attribute to see if the user requested a specific beacon
interval, if not default to 100 TU (wext too).

nl80211: Add set/get for frag/rts threshold and retry limits

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

Add new nl80211 attributes that can be used with NL80211_CMD_SET_WIPHY
and NL80211_CMD_GET_WIPHY to manage fragmentation/RTS threshold and
retry limits.

Since these values are stored in struct wiphy, remove the local copy
from mac80211 where feasible (frag & rts threshold). The retry limits
are currently needed in struct ieee80211_conf, but these could be
eventually removed since the driver should have access to the values
in struct wiphy.

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.

cfg80211: add cipher capabilities

2009-04-22T20:54:40+00:00

This adds the necessary code and fields to let drivers specify
their cipher capabilities and exports them to userspace. Also
update mac80211 to export the ciphers it has.

cfg80211: send regulatory beacon hint events to userspace

2009-04-22T20:54:40+00:00

This informs userspace when a change has occured on a world
roaming wiphy's channel which has lifted some restrictions
due to a regulatory beacon hint.

Because this is now sent to userspace through the regulatory
multicast group we remove the debug prints we used to use as
they are no longer necessary.
