4367eec439 mesh: Do not use RX MGTK as RX IGTK
The previous implementation was incorrect in forcing the MGTK to be used
as the IGTK as well. Define new variable for storing IGTK and use that,
if set, to configure IGTK to the driver. This commit does not yet fix
AMPE element parsing to fill in this information.

fccba2c946 mesh: Generate a separate TX IGTK if PMF is enabled
Previous implementation was incorrectly using MGTK also as the IGTK and
doing this regardless of whether PMF was enabled. IGTK needs to be a
independent key and this commit does that at the local TX side.

The current AMPE element construction and parsing is quite broken, so
this does not get add the IGTKdata field there.

c86bef2913 wpa_supplicant: Make GAS Address3 field selection behavior configurable
IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS.
wpa_supplicant used to use the actual BSSID value for all such frames
regardless of whether the destination STA is a member of the BSS.

P2P does not follow this rule, so P2P Public Action frame construction
must not be changed. However, the cases using GAS/ANQP for non-P2P
purposes should follow the standard requirements.

Unfortunately, there are deployed AP implementations that do not reply
to a GAS request sent using the wildcard BSSID value. The previously
used behavior (Address3 = AP BSSID even when not associated) continues
to be the default, but the IEEE 802.11 standard compliant addressing
behavior can now be configured with gas_address3=1.

a26c9c2e71 Fix sending non-Public Action frames over P2P Device interface
The P2P Device interface can only send Public Action frames. Non-Public
Action frames must be sent over a group interface. The previous
implementation sometimes tried to send non-Public Action frames such as
GO Discoverability over the P2P Device interface, however, the source
address of the frame was set to the group interface address so the code
in offchannel.c knew to select the correct interface for the TX.

The check breaks when the P2P Device and group interfaces have the same
MAC address. In this case the frame will be sent over the P2P Device
interface and the send will fail.

Fix this problem in two places:
1. In offchannel, route non-Public Action frames to the GO
   interface when the above conditions are met.
2. When a TX_STATUS event arrives on such routed frame, it will
   arrive on the GO interface but it must be handled by the P2P Device
   interface since it has the relevant state logic.

3b11ad34eb Send CTRL-EVENT-REGDOM-CHANGE event on the parent interface
The NL80211_CMD_WIPHY_REG_CHANGE can be handled by any of the
interfaces that are currently controlled by the wpa_supplicant.
However, some applications expect the REGDOM_CHANGE event to be

(and do not expect the event on any of child interfaces).

To resolve this, when processing NL80211_CMD_WIPHY_REG_CHANGE,
find the highest parent in the chain, and use its control interface
to emit the CTRL-EVENT-REGDOM-CHANGE event.

f42c3ceb94 mesh: Calculate MTK before sending it to MAC in case Open is dropped
IEEE Std 802.11-2012 13.5.6.3 State transitions require an action
sending SETKEYS primitive to MAC when OPN_ACPT event occurs in CNF_RCVD
state in case of AMPE is used, but since MTK calculation is missed in
this condition, all zero valued key are passed to MAC and cause unicast

followed by retransmitted Open frame.

2a3f56502b Reject SET commands with newline characters in the string values
Many of the global configuration parameters are written as strings
without filtering and if there is an embedded newline character in the

This fixes an issue where wpa_supplicant could have updated the

accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the value of a parameter before passing it to
wpa_supplicant.

This could allow such an untrusted user to inject almost arbitrary data
into the configuration file. Such configuration file could result in
wpa_supplicant trying to load a library (e.g., opensc_engine_path,
