mac80211: don't use master netdev name

2009-06-10T17:28:39+00:00

Always use the wiphy name instead.

cfg80211: add rfkill support

2009-06-03T18:06:14+00:00

To be easier on drivers and users, have cfg80211 register an
rfkill structure that drivers can access. When soft-killed,
simply take down all interfaces; when hard-killed the driver
needs to notify us and we will take down the interfaces
after the fact. While rfkilled, interfaces cannot be set UP.

cfg80211: move txpower wext from mac80211

2009-06-03T18:06:14+00:00

This patch introduces new cfg80211 API to set the TX power
via cfg80211, puts the wext code into cfg80211 and updates
mac80211 to use all that. The -ENETDOWN bits are a hack but
will go away soon.

mac80211: handle -EALREADY on cfg80211 op assoc req

2009-06-03T18:05:11+00:00

When the SME requests to associate to an open AP
ieee80211_sta_set_extra_ie() can be called with zero IE
length. When this happens or when the extra IE has already
been set -EALREADY is passed down and the supplicant will
complain that the operation is already in progress and it will
not let us associate. We correct this by treating -EALREADY
from ieee80211_sta_set_extra_ie() as a success just as we do
for wext.

cfg80211: validate AID of stations being added

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

We have some validation code in mac80211 but said code will
force an invalid AID to 0 which isn't a valid AID either;
instead require a valid AID (1-2007) to be passed in from
userspace in cfg80211 already. Also move the code before
the race comment since it can only be executed during STA
addition and thus is not racy.

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).
