6700a277a9 Avoid dropping ctrl_iface on ENOBUFS error burst
These bursts can result in control interface monitors being detached
even if the external program is still working properly. Use much larger
error threshold for ENOBUFS to avoid this.

cf4783e35f Deauthenticate instead of disassociate on disconnect command
This clears up authentication state in the driver and in case of
cfg80211, unlocks the BSS entry for the previously used AP.

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.

17a4734dc4 Optimize post-WPS scan based on channel used during provisioning
Scan only the frequency that was used during provisioning during the
first five scans for the connection. This speeds up connection in the
most likely case where the AP remains on the same channel. If the AP is
not found after these initial scans, all channels will be scanned.

addb584881 EAP-MD5: Use conditional success decision
The server may still reject authentication at this point, so better
use conditional success decision. This allows the potentially
following EAP-Failure message to be processed properly. [Bug 354]

721abef9b3 Allow advertising of U-APSD functionality in Beacon
hostapd does not implement UAPSD functionality. However, if U-APSD
functionality is implemented outside hostapd, add support to advertise
the functionality in beacon.

86d4f806da Add ctrl_iface command for triggering a roam to a specific BSS
'wpa_cli roam <bssid>' can now be used to test roaming within an ESS
(e.g., for FT over-the-air). This command will bypass a new scan and
will select the BSS based on the specified BSSID. It is responsibility
of the caller to make sure that the target AP is in the BSS table.
This can be done, e.g., by running a scan before the roam command,
if needed.

e7846b6859 FT: Clean up wpa_sm_set_ft_params() by using common parse
Instead of parsing the IEs in the callers, use the already existing
parser in wpa_ft.c to handle MDIE and FTIE from initial MD association
response. In addition, this provides more complete access to association
response IEs to FT code which will be needed to fix FT 4-way handshake
message 2/4.

addition, this resolves issues for 802.11r FT-over-DS by allowing
authentication state to be set locally even when no actual

26e23750b9 FT: Fix FT 4-Way Handshake to include PMKR1Name in messages 2 and 3
IEEE Std 802.11r-2008, 11A.4.2 describes FT initial mobility domain
association in an RSN to include PMKR1Name in the PMKID-List field
in RSN IE in messages 2/4 and 3/4. This makes the RSN IE not be
bitwise identical with the values used in Beacon, Probe Response,
(Re)association Request frames.

The previous versions of wpa_supplicant and hostapd did not add the
PMKR1Name value in EAPOL-Key frame and did not accept it if added
(due to bitwise comparison of RSN IEs). This commit fixes the
implementation to be compliant with the standard by adding the
PMKR1Name value into EAPOL-Key messages during FT 4-Way Handshake and
by verifying that the received value matches with the value derived
locally.

This breaks interoperability with previous wpa_supplicant/hostapd
versions.

d9a27b0455 Fix SME to update WPA/RSN IE for rsn_supp module based on AssocReq
When using wpa_supplicant SME (i.e., using nl80211), the rsn_supp
module was not informed of the WPA/RSN IE that was used in
(Re)Association Request frame. This broke roaming between APs that
use different security policy (e.g., changing between WPA/TKIP and
WPA2/CCMP APs) or when using PMKSA caching.

68532a9ceb Avoid hostapd segfault on invalid driver association event
Running hostapd and wpa_supplicant on the same interface at the same
time is not expected to work, but it should not cause hostapd to crash.

IF WPA/RSN parameters were changed or WPA/RSN was disabled, the
WPA/RSN IE in Beacon/Probe Response frames was only update with
set_beacon(). We need to do this with set_generic_elem(), too, to
work with all driver wrappers.

used from the input string in case of success.
