Various pieces of the P2P code assume that P2P is enabled, so make
the D-Bus code not call the P2P stuff if P2P is disabled. Also
ensures that if P2P is disabled a suitable error is returned to
the D-Bus caller.

The read, write, read-write permissions can be figured out from
getter/setter function pointers, so there is no need for maintaining
that information separately.
If uapsd is explicitly enabled, set conf->bss->wmm_enabled and
conf->bss->wmm_uapsd to enable (and advertise) uapsd.

Some compilers complain about fwrite calls if the return value is
not checked, so check the value even if it does not really make
much of a difference in this particular case.
The internal TLS implementation assumes that the certificate chain
is ordered by issuer certificate following the certificate that it
signed. Add the certificates to the chain in suitable order when
loading multiple certificates.
Commit e1d526293b added code for verifying
whether the receive Probe Request frame was indicating support for only
802.11b rates, but it missed the for loop for the extended supported
rates element. Add that to fix the validation code for cases where
non-802.11b rates are in the extended supported rates element.
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.

Fix the previous code that was hardcoding the p2p parameter based
on the driver P2P capability regardless of whether the connection
was really used for P2P or not.
Currently, wpa_driver_nl80211_authenticate() changes the interface type
to station. However, in case of P2P, we need to change the interface
type to P2P_CLI.
Add p2p field to the authentication params, and consider it for choosing
the correct interface type.

Commit 9f51b11395 added support for P2P
interfaces when adding a new interface. However, it didn't handle the
case in which the same interface is being used and its type is being
changed. Add support for this case.
Consequently, when doing "ap_scan_as_station" we now need to save the
actual AP interface type (AP/P2P GO) in order to restore it properly.
For that, change ap_scan_as_station type from int to nl80211_iftype, and
set it to NL80211_IFTYPE_UNSPECIFED when not used.

When driver_nl80211.c has to set the netdev down to change iftype, an
RTM_NEWLINK event is generated. Do not generate
EVENT_INTERFACE_DISABLED event based on that.
This makes sure that the old connection is not maintained if the new
configuration does not allow it anymore. In addition, it is better to
use wpa_supplicant_clear_connection() instead of just clearing
wpa_s->current_ssid here to keep things in sync.
When the BSS table size limit has been reached, drop first the oldest
BSS entries for which there is not a matching network in the
configuration based on SSID (wildcards are ignored). This makes it
less likely to hit connection issues in environments with huge number
of visible APs.
Reassociation Request/Response frame validation need to count all IEs in

Only accept Probe Request frames that have a Wildcard BSSID and a
destination address that matches with our P2P Device Address or is the
broadcast address per P2P specification 3.1.2.1.1.
The current implementation of p2p_intra_bss doesn't work since the flag
isn't propagated into the corresponding hostapd config, so AP code will
never enable AP isolation and will in fact disable it again after it had
been enabled by the P2P code.

The paths pointer could have been NULL when going through the shared
freeing path in error case. Avoid the NULL pointer dereference by
checking whether that is the case. In addition, remove unnecessary
gotos to make the function more readable.
When a new interface is created and already has a separate MAC address
assigned by the kernel, then we need to use that address, not just when
we've created a locally administered address.
This fixes use_p2p_group_interface=1 for iwlagn as it already makes
mac80211 assign an address for a second interface since the hardware has
two addresses assigned.
