0382097ef3 Use set_key addr to distinguish default and multicast keys
Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).

3ac17eba31 P2P: Add initial support for driver-based P2P management
This adds partial callbacks and events to allow P2P management to be
implemented in a driver/firmware. This is not yet complete and is
very much subject to change in the future.

190b9062b2 P2P: Add option for offloading off-channel TX to the driver
With the new kernel functionality coming to Linux to allow off-channel
TX, we can take advantage of that in the P2P code that currently uses
remain-on-channel. If a driver advertises support for it, it will be
asked to handle off-channel TX by itself.

6859f1cb24 Enable sharing of scan result events among virtual interfaces
When controlling multiple virtual interfaces on the same physical
radio, share the scan results events with sibling interfaces. This
decreases the time it takes to connect many virtual interfaces.

This is currently only supported on Linux with cfg80211-based
drivers when using nl80211 or wext driver interface.

0c80427d77 NDIS: Fix association for WPS provisioning with protected AP
Some NDIS drivers require a workaround to allow them to associate
with a WPS AP that is already using protection (Privacy field = 1).
Let driver_ndis.c know if the AP is already using Privacy and if so,
configure a dummy WEP key to force the driver to associate.

f3585c8a85 Simplify driver_ops for virtual interface add/remove
There is no absolute requirement for separating address allocation
into separate functions, so simplify the driver wrapper interface
to use just if_add and if_remove instead of adding the new
alloc_interface_addr() and release_interface_addr() functions.

if_add() can now indicate if the driver forced a different interface
name or address on the virtual interface.

code.

55777702cd Add driver API functionality for off-channel Action frames
This adds new commands and events for allowing off-channel Action
frame exchanges to be requested. This functionality is not yet used
and is only fully supported by driver_test.c at this point.
driver_nl80211.c has support for the remain-on-channel commands, but
the Action frame TX/RX part is still pending review for the kernel
code and as such, is not yet included here.

14f7938660 Merge driver ops set_wps_beacon_ie and set_wps_probe_resp_ie
set_ap_wps_ie() is not used to set WPS IE for both Beacon and Probe
Response frames with a single call. In addition, struct wpabuf is used
instead of separate u8* and length fields. This avoids duplicated
allocation of the IEs and simplifies code in general.

fbbfcbac29 hostapd: Add WDS (4-address frame) mode with per-station interfaces
This mode allows associated stations to use 4-address frames to allow
layer 2 bridging to be used. At least for the time being, this is only
supported with driver=nl80211.

9008a3e44d Merge get_seqnum_igtk() driver op with get_seqnum()
IEEE 802.11w uses distinct key indexes (4 and 5) so the same
get_seqnum() handler can be used to fetch packet number for both
TKIP/CCMP and BIP(using IGTK).

Since the new get_seqnum_igtk() handler was not actually implemented by
any driver wrapper, this may also fix BIP/IGTK sequence number reporting
with driver_nl80211.c.

driver_nl80211.c is now including this code unconditionally, so that
the functions are not limited only for hostapd.

90973fb2fd Remove src/common from default header file path
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.

In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.

61693eaa80 hostapd: Remove unused passive scan functionality

mechanism.

ad1e68e6b5 Clean up HT40 scan and share nl80211 scanning code
Instead of adding a new driver_ops for fetching neighbor BSS data (that
nl80211 driver interface had to scan during initialization), share the
same scan operations that wpa_supplicant is using. This gets rid of
duplicated scan code in driver_nl80211.c (and better yet, removes large
part of old WEXT code).

hostapd interface initialization is now completed in a callback, if
needed, i.e., he_features channel/hw_mode selection can use as much time
as needed. This can also help with radar detection in the future.

This commit merges the driver_ops structures and implementations from

there is room for number of cleanups to share code between the hostapd
and wpa_supplicant parts of the wrappers to avoid unnecessary source
code duplication.

c2a0407851 Add SME support (separate authentication and association)
This can be used, e.g., with mac80211-based Linux drivers with
nl80211. This allows over-the-air FT protocol to be used (IEEE
802.11r).

Since the nl80211 interface needed for this is very recent (added
today  into wireless-testing.git), driver_nl80211.c has backwards
compatibility code that uses WEXT for association if the kernel does
not support the new commands. This compatibility code can be
disabled by defining NO_WEXT_COMPAT. That code will also be removed
at  some point to clean up driver_nl80211.c.

a14bda9d9d driver_ndis: Detect Native 802.11 drivers (NDIS 6, Vista)
This is just there very first step on being able to do something with
wireless LAN on Vista. There is some example code for requesting a scan,
but it does not work in its current form. Anyway, this adds a wpa_printf
noting that Native 802.11 drivers are not yet supported.

c472ef754d driver_ndis: Add PAE group address to the multicast address
This is done with wired interfaces to fix IEEE 802.1X authentication
when the authenticator uses the group address (which should be happening
with wired Ethernet authentication).

This allows wpa_supplicant to complete wired authentication successfully
on Vista with a NDIS 6 driver, but the change is likely needed for
Windows XP, too.
