As per IEEE Std 802.11ac-2013, 'Maximum A-MPDU Length Exponent' field
value is in the range of 0 to 7. Previous implementation assumed EXP0 to
be the maximum length (bits 23, 24 and 25 set) what is incorrect.
This patch adds options to set it up within the 0 to 7 range.

The special case of non-zero status code used in a GAS Comeback Response
frame to indicate that additional delay is needed before the response is
available was not working properly. This case needs to allow the status

Add IPv6 support when using udp/udp-remote control interface using the
following new build configuration options:
CONFIG_CTRL_IFACE=udp6
CONFIG_CTRL_IFACE=udp6-remote
This is useful for testing, while we don't need to assign IPv4 address
(static or using DHCP) and can just use auto configured IPv6 addresses
(link local, which is based on the MAC address). Also add scope id
support for link local case.
For example,
./wpa_cli
./wpa_cli -i ::1,9877
./wpa_cli -i fe80::203:7fff:fe05:69%wlan0,9877

Confirm-before-commit validation step allowed execution to continue on
error case. This could result in segfault in sae_check_confirm() if the
temporary SAE data was not available (as it would not be, e.g., in case
of an extra SAE confirm message being received after successful
exchange). Fix this by stopping SAE processing immediately after
detecting unexpected state for confirm message. In addition, make the
public sae.c functions verify sae->tmp before dereferencing it to make
this type of bugs less likely to result in critical issues.

This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.
The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:
ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100
DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

The new control interface command RADIO_WORK can be used by external

exclusive radio control is needed, e.g., for offchannel operations. If
such operations are done directly to the driver, wpa_supplicant may not
have enough information to avoid conflicting operations. This new

to avoid issues with such cases.

WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.
