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.

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.

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
by lower level drivers.

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.
If the driver supports HT20, set the config parameter ieee80211n
to enable it. This does not enable HT40.

Regardless of how the AP mode is disabled, wpa_supplicant_ap_deinit()
must be called. Make sure this happens on all paths by calling the
deinit function from wpa_supplicant_mark_disassoc().
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.
The patch clears the keys configured when hostapd reloads
its configuration.

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.
This is required for cross-compilation support on certain
platforms to avoid changing the pkg-config files themselves.

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:

Make sure that the WPA and EAPOL state machines do not hold a pointer
to a network configuration that is about to be freed. This can fix
potential issues with references to freed memory.

Do not emit network objects during P2P group formation since such
network objects can confuse certain apps. Instead, a persistent group
object is created to allow apps to keep track of persistent groups.
Persistent group objects only represent the info needed to recreate the

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.

Need to define CONFIG_NO_PBKDF2 even though the crypto cleanup moved
the function to a separate file since there is conditional code in
wpa_supplicant/config.c. In addition, wpa_passphrase should not be
built at all if passphrase functionality is removed.
This file is a part of the radiotap parser that Andy Green agreed to
relicense under the BSD license (per email, 11 Aug 2007 07:42:05
+0100). The copyright/license statement was updated in radiotap.c,
but this radiotap_iter.h file was forgotten at that point.
In set_key handler, the seq[8] is in little endian order defined by
WPA. BSD kernel uses a u_int64_t value ik_keyrsc to represent it
internally. The kernel expects the native endian order for the value.
Thus, we need to detect the endian order and swap bytes when
necessary.
These checks were previously skipped if the scan result included WPA
or RSN IE. However, that can result in selecting a network that does
not match local configuration in some cases.
This fixes an issue with SA Query Response frames not being processed
anymore after wpa_supplicant started registering a handler for those.
This handler registration is in generic driver_nl80211.c code, so
hostapd uses it, too.
There are some corner cases, where the wpa_supplicant_req_scan() call
may end up scheduling a scan even if we are about to start a GO. Avoid
this by explicitly marking the GO network to be selected for the next
connection.
