This change is a first step in better supporting different driver
architectures for AP mode operations with nl80211. This commit in
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.
Split WPA initialization into two parts so that the Beacon frames can be
configured fully before the initial keys (GTK/IGTK) are configured. This
makes it easier for drivers that depend on the AP security mode being
fully set before the keys are configured.
This avoids a request to the driver to first start beaconing before
the WPA/RSN IE has been generated and then immediately changing the
beacon IEs once the WPA/RSN IE is ready.
Such using params->wpa_ie to figure out whether the connection is for
WPA/WPA2 is not correct since that buffer is used also to add WPS IE. In
case of WPS, do not add NL80211_ATTR_WPA_VERSIONS to avoid confusing
drivers.
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.
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.
Reassociation Request/Response frame validation need to count all IEs in
the RIC. In addition, TIE is not protected, so it should not be included
in the count.

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.
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.

Add support to wpa_supplicant for device-based GTK rekeying. In order to
support that, pass the KEK, KCK, and replay counter to the driver, and
handle rekey events that update the latter.

Send STA flags to kernel when adding a new station. This ensures

When adding a new station, set the STA flags as part of the sta_add()
command. This ensures the flags are up to date when the station is added

A new hostapd configuration parameter, disable_pmksa_caching=1, can now
be used to disable PMKSA caching on the Authenticator. This forces the
stations to complete EAP authentication on every association when WPA2
is being used.
In general, this patch attemps to extend commit
00468b4650 with dbus support.
This can be used by dbus client to implement subject match text
entry with preset value probed from server. This preset value, if
user accepts it, is remembered and passed to subject_match config
for any future authentication.

Data path is broken when hostapd reloads its configuration
disabling the security which was previously enabled (WEP/WPA),
using kill -1, as old keys were not cleared.

This phase1 parameter for TLS-based EAP methods was already supported
with GnuTLS and this commit extends that support for OpenSSL and the
internal TLS implementation.
Fix a bug with the current dev_found()/dev_lost() usage. Previously
in p2p_device_free() dev_lost() was invoked for devices that had
not been dev_found(). This caused dbus related msgs to stderr like:
"Attempted to unregister path (path[0] = fi path[1] = w1) which isn't
registered"

Previously hostapd just masked the STAs HT caps with its own. However,
some HT caps are not symmetric and as such need to be handled
different.
hostapd shouldn't overwrite the STAs SMPS mode as otherwise the driver
cannot know it has to use RTS/CTS to wake the receiver from dynamic
SMPS for MCS rates > 7.
hostapd shouldn't mask the RX and TX STBC caps with it's own. They are
already handled in a special case below.
