The WPS mode was already verified when the AP was configured for
WPA/WPA2, but this was not done with AP that was in open mode.
Fix this by allowing wpa_supplicant_ssid_bss_match() to be called
in non-WPA configuration, too. With this change, wps_pbc BSSID
command will wait until the specified target AP is in active PBC
mode before trying to connect to it.
If a station received unprotected Deauthentication or Disassociation
frame with reason code 6 or 7 from the current AP, there may be a
mismatch in association state between the AP and STA. Verify whether
this is the case by using SA Query procedure. If not response is
received from the AP, deauthenticate.
This implementation is only for user space SME with
driver_nl80211.c.
Some new code will require access to P2P group members, so add API to
retrieve the number of members and iterate the members themselves.

Some new code I'm working on will need the scan_res_handler assigned all
the time in certain circumstances, so the easiest way is to reset it
within the handler. This is currently prevented by the way the code in
the event handler works -- change that to permit such usage.

The array's type should be given as the proper
DBUS_TYPE_STRING_AS_STRING, but evidently it
doesn't matter since it's all packed into a
variant type.

If there is a pending GO Negotiation when p2p_cancel is used,
unauthorize the peer to avoid immediate reconnection from being
accepted without a new p2p_connect command.
We should cancel group formation completely on PBC overlap instead
of just partially notifying that operations were stopped. There is
no point in waiting for the group formation timeout in this case.
The use of the pcap subdirectory seems to be limited to some of the
newer Linux distros only, so use the older paths to pcap.h and
pcap-bpf.h to make wlantest bit more easier to compile on older
systems.
This can be used by external programs (e.g., wlantest_cli) to inject
raw frames (hex dump of the frame header and body). The data can be
requested to be sent as-is or protected with the current key.
Previously, pairwise and group cipher suites were configured only
when kernel SME (nl80211 connect API) was used. However, mac80211
needs this information even in the user space SME case for one
thing: to disable HT when TKIP/WEP is used. Add
NL80211_ATTR_CIPHER_SUITES_PAIRWISE to fix this special case with
user space SME. This allows mac80211 to disable HT properly when
the AP is configured with configuration that is not allowed.
This add preliminary code for setting the per-STA RX GTK for
RSN IBSS when nl80211 drivers. For some reason, this does not
seem to fully work, but at least driver_nl80211.c is now aware of
what kind of key is being set and the whatever is missing from
making this key configuration go through should be specific to
nl80211/cfg80211.
The frame needs to be sent from an individual (non-group) address,
so drop invalid frames before sending Deauth/Disassoc frames to
not associated STAs.
This unref is guaranteed to be freeing a NULL pointer.
Tested manually: use dbus-send to send an invalid debug level parameter
Before change:
$ dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:msgdumpf
Error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply
(timeout by message bus)
(and then wpa_supplicant crashes)
After change:
$ dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:msgdumpf
Error fi.w1.wpa_supplicant1.InvalidArgs: Did not receive correct message

One of the pointers to the PAC buffer was not updated after realloc
and if the realloc ended up returning new pointer, the *pos pointer
was still pointing at the old location (i.e., freed memory at
this point).
When controlling multiple virtual interfaces on the same physical
radio, share the scan results events with sibling interfaces. This
decreases the time it takes to connect many virtual interfaces.
This is currently only supported on Linux with cfg80211-based
drivers when using nl80211 or wext driver interface.

Some drivers are not providing exactly reliable error codes (e.g.,
with WEXT), but others may actually indicate reliable information.
Allow driver wrappers to indicate if that is the case and use
optimizations if so. For now, this improves nl80211 with
NL80211_CMD_CONNECT for a case where connection request fails.
mac80211 can indicate this mainly because of channel selection
conflicts with other vifs. If there is another BSS on another
channel, we should try to connect to it instead.
driver_param=use_p2p_group_interface=1 can now be used to test
nl80211-drivers with separate P2P group interface. In other words,
the main interface (e.g., wlan0) is reserved for P2P management
operations and non-P2P connections and a new group interface (e.g.,
p2p-wlan0-0) is created for the P2P group.
This implementation is very minimal, i.e., it only support address
allocation for a single P2P group interface (if the driver does not
handle this internally). In addition, not all functionality has yet
been tested, so for now, this is disabled by default and needs that
special driver_param to enable.
WPA_DRIVER_FLAGS_P2P_MGMT_AND_NON_P2P flag can now be used to
indicate that the initial interface (e.g., wlan0) is used for
P2P management operations and potentially non-P2P connections.
This is otherwise identical to
WPA_DRIVER_FLAGS_P2P_DEDICATED_INTERFACE, but the possibility of
non-P2P connections makes some operations differ.
