cc28ad8cdf Fix Deauth/Disassoc callback handling with test frames
The Deauth/Disassoc TX status callbacks were ending up kicking the
station entry from kernel driver when test functionality was used to
inject Deauth/Disassoc frames from the AP with the purpose of leaving
the local association in place. Fix this by using STA flags to figure
out whether there was a pending callback for the frame that we need
to act on.

In addition, add forgotten functionality for the Disassoc TX status
callback to match the behavior with Deauth.

64fa840a97 nl80211: Fix WPA_VERSIONS attribute for Connect command
The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().

ae9c400358 WPS ER: Fix UPnP XML Device Description parser to find correct device
The device description file may include multiple devices. Improve the
simplistic parser by first trying to find the WFADevice:1 device before
fetching the device parameters. While this is still far from complete
XML parsing, this should address the most common root device
specifications.

86957e6298 nl80211: Support AP mode probe/action frame TX/RX without monitor iface
This allows non-mac80211 drivers to report received Probe Request
frames to user space and Probe Response and Action frames to be sent
from user space when using AP/P2P GO mode.

4dc03726de Delay STA entry removal until Deauth/Disassoc TX status in AP mode
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.

This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.

17f6b90056 WPS: Wait for EAPOL-Start unless WPS 2.0 station as workaround
Extend the code that waits for the station to send EAPOL-Start before
initiating EAPOL authenticator operations to cover the case where the
station includes WPS IE in (Re)Association Request frame if that IE
does not include support for WPS 2.0. While this should not really
be needed, this may help with some deployed WPS 1.0 stations that do
not support EAPOL operations correctly and may get confused of the
EAP-Request/Identity packets that would show up twice if EAPOL-Start
is transmitted.

9ca47fff8c WPS: Drop responses from ER to a STA that is not in WPS protocol

de6e463f57 Make sure that EAP callbacks are not done if state machine has been removed
It is possible to get a response for a pending EAP callback after the
EAP state machine has already completed its work or has timed out. For
those cases, make sure that the callback function is not delivered since
it could result in NULL pointer dereferences.

167dc97501 WPS: Fix M2/M2D Config Methods to include PushButton even if PBC not in use
The Config Methods attribute in M2 and M2D messages is supposed to

such, it should not depend on whether PBC mode is currently active or
not. That will only affect the Selected Registrar Config Methods and

19c3b56685 Replace set_beacon() driver op with set_ap()
This change is a first step in better supporting different driver

itself does not add new functionality, but it makes it easier to add
new AP mode parameters to address needs of drivers that have more of
the MLME/SME in firmware or kernel.

case of WPS, do not add NL80211_ATTR_WPA_VERSIONS to avoid confusing

non-802.11b rates are in the extended supported rates element.

6aeeb6fa21 dbus: clean up new D-Bus interface getters and setters
A number of fixes/improvements here:

1) Remove casting of getter/setter function types which allows
us to change the prototypes in the future and not have hard-to-find
runtime segfaults

2) Instead of having the getters create a fake reply message which
then gets its arguments copied into the real reply message, and is
then disposed, just pass message iters around and have them add
their arguments to the message itself

3) For setters, just pass in the message iter positioned at the
start of the argument list, instead of each setter having to skip
over the standard interface+property name

4) Convert error handling to use DBusError and return the error
back down through the call stacks to the function that will
actually send the error back to the caller, instead of having a
fake DBusMessage of type DBUS_MESSAGE_TYPE_ERROR that then
needs to have the error extracted from it.

But most of all, this fixes various segfaults (like rh #725517
and #678625) which were caused by some functions deep down in the
getter callpaths wanting a source DBusMessage* when the getters were
used for two things: signals (which don't have a source DBusMessage)
and methods (which will have a source DBusMessage that's being
replied to).  This duality made the code fragile when handling
errors like invalid IEs over the air.
