tests: Add test for hostapd cli ordering
When the 'SET wpa 2' command is executed last, it seems to somehow
reset parts of the settings, causing hostapd to beacon with the
pairwise cipher suite selector set to 00-0F-AC:0 (none/use-group).
This is not permitted and should be rejected; wpa_supplicant also
cannot connect.

Do not clear RSN parameters before full configuration
This fixes an issue where hostapd SET command is used to configure RSN
parameters and the wpa parameter is sent after the other parameters.
Previously, the default case here ended up clearing rsn_pairwise and
wpa_pairwise values and once wpa=2 was finally set, the cipher
configuration had already been lost.

This corrects the type of dev_passwd_id in GONegotiationRequest event.
This field is packed as DBUS_TYPE_UINT16 but in
wpas_dbus_interface_signals it was "i" which is DBUS_TYPE_INT32.
Android: Set ctrl_iface client socket group (AID_WIFI) separately
Split chown() call in wpa_ctrl_open() and wpa_ctrl_open2() to allow the
group id to be set even if the process does not have privileges to
change the owner. This is needed for modules that need to communicate
with wpa_supplicant since without the group change, wpa_supplicant may
not have privileges to send the response to a control interface command.
Android: Avoid same per-iface and global ctrl socket
Android platform assigns the same socket id if the socket identifier in
conf->ctrl_interface and global->params.ctrl_interface (parameter for
android_get_control_socket) point to the same Android specific control
socket. This ends up having two eloop socket handlers registered for the
same file descriptor and thus, two attempt to receive and process each
command. This can result in unexpected failure, e.g., the prefix IFNAME=
for any command is valid for global socket handler, but results in
UNKNOWN COMMAND response from the per-interface ctrl socket handler).
Since it might be possible to end up with this type of invalid
configuration in OTA upgrade, compare the socket identifiers and do not
open the ctrl socket on the respective interface if both point to same.
This allows the Wi-Fi framework to use the global control interface.
Do not copy STA VHT capabilities if VHT is not enabled for AP
Previously, station's VHT information elements were copied and passed
regardless of the AP's VHT configuration. As a result, AP with VHT
disabled in configuration could have ended up transmitting packets in
VHT rates though AP is not advertising VHT support. Fix this by copying
the station's VHT capabilities only when AP supports VHT (both hardware
and configuration).
tests: WPA2-Enterprise interactive identity entry and ENABLE_NETWORK
This verifies that ENABLE_NETWORK does not trigger reconnection if
already connected. The previous commit fixed a case where it was
possible for that to happen.
Avoid reconnection on ENABLE_NETWORK if already connected
This was already the case for most command sequences, but it was
possible for wpa_s->reassociate to be set to 1 when CTRL-RSP-* commands
were used to set identity, password, or passphrase for EAP
authentication. In such cases, ENABLE_NETWORK issued after the
connection was completed could result in a new connection attempt
(likely reconnection back to the same BSS).
Fix this by checking whether an actual connection is already present
even if wpa_s->reassociate is set when processing the ENABLE_NETWORK
command.
Update AP WPA/RSN IE on all associations if driver can select BSS
It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.
Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
BSS.
Drop some control interface debug print verbosity for send operations
These prints were at DEBUG level (-d), but they can be very frequent, so
drop them to MSGDUMP (-dd). This allows the prints to be suppressed in
common debugging cases while still leaving them easily enablable to
debug control interface issues without having to enable excessive
debugging.
Reduce debug verbosity for read-only control interface commands
Commands like BSS and GET_NETWORK are used in some cases very frequently
and those can increase the amount of debug information from
wpa_supplicant without significant benefit. These were logged at the
DEBUG level (-d). Move logging of such read-only commands (i.e., no new
wpa_supplicant operation is started based on it) to EXCESSIVE level
(-ddd) which was already used for the PING command.
WPA: Do not print GTK in debug log unless requested
The GTK value received in RSN (WPA2) group rekeying did not use the
wpa_hexdump_key() version of debug printing that is conditional on -K
being included on the command line.
Use shorter variables for storing the attribute lengths and group these
variables together to allow compiler to pack them more efficiently. This
reduces the struct size from 960 bytes to 760 bytes in 64-bit builds.
This reduces stack use in number of functions.

WPS: Fix num_probereq_cb clearing on DISABLE to avoid segfault
Reset hapd->num_probereq_cb to 0 on an interface deinit to avoid
unexpected behavior if the same interface is enabled again without fully
freeing the data structures. hostapd_register_probereq_cb() increments
hapd->num_probereq_cb by one and leaves all old values unchanged. In
this deinit+init case, that would result in the first entry in the list
having an uninitialized pointer and the next Probe Request frame
processing would likely cause the process to terminate on segmentation
fault.
This issue could be hit when hostapd was used with WPS enabled (non-zero
wps_state configuration parameter) and control interface command DISABLE
and ENABLE were used.
This adds a Python-based minimal WSC protocol implementation to allow
more testing coverage to be reached for various error cases in protected
attributes. The wps_ext test case completes successful exchange in both
the Enrollee and Registrar roles acting in the middle of AP and STA. The
other test cases cover error cases.

TDLS: Use proper IE parsing routine for non-EAPOL-Key cases
wpa_supplicant_parse_ies() was never supposed to be used as a generic IE
parser, i.e., it is for the specific purpose of parsing EAPOL-Key Key
Data IEs and KDEs. TDLS used this function for parsing generic AP IEs
and while that works, it resulted in confusing "WPA: Unrecognized
EAPOL-Key Key Data IE" debug messages. Clean this up by using
ieee802_11_parse_elems() for the cases where generic IEs are being
parsed.
Add station tracking based on other management frame subtypes
This extends the previous tracking design to add a station entry based
on other management frames than Probe Request frames. For example, this
covers a case where the station is using passive scanning.
wpa_gui: Increase control interface message buffer for LIST_NETWORKS

Add option to reject authentication on 2.4 GHz from dualband STA
The new no_auth_if_seen_on=<ifname> parameter can now be used to
configure hostapd to reject authentication from a station that was seen
on another radio.
This can be used with enabled track_sta_max_num configuration on another
interface controlled by the same hostapd process to reject
authentication attempts from a station that has been detected to be
capable of operating on another band, e.g., to try to reduce likelihood
of the station selecting a 2.4 GHz BSS when the AP operates both a 2.4
GHz and 5 GHz BSS concurrently.
Note: Enabling this can cause connectivity issues and increase latency for
connecting with the AP.
Indicate CTRL-EVENT-AUTH-REJECT event on authentication rejection
This allows control interface monitors to get more detailed information
in cases where wpa_supplicant-based SME receives an Authentication frame
with non-zero status code.
Add option to ignore Probe Request frames on 2.4 GHz from dualband STA
The new no_probe_resp_if_seen_on=<ifname> parameter can now be used to
configure hostapd to not reply to group-addressed Probe Request from a
station that was seen on another radio.
This can be used with enabled track_sta_max_num configuration on another
interface controlled by the same hostapd process to restrict Probe
Request frame handling from replying to group-addressed Probe Request
frames from a station that has been detected to be capable of operating
on another band, e.g., to try to reduce likelihood of the station
selecting a 2.4 GHz BSS when the AP operates both a 2.4 GHz and 5 GHz
BSS concurrently.
Note: Enabling this can cause connectivity issues and increase latency
for discovering the AP.
hostapd: Add mechanism to track unconnected stations
hostapd can now be configured to track unconnected stations based on
Probe Request frames seen from them. This can be used, e.g., to detect
dualband capable station before they have associated. Such information
could then be used to provide guidance on which colocated BSS to use in
case of a dualband AP that operates concurrently on multiple bands under
the control of a single hostapd process.
For now, there is no support for passing extended_capa pointers through
the driver_privsep.c interface from wpa_priv. Avoid leaving bogus
pointers by explicitly clearing these on both wpa_priv and
wpa_supplicant sides.
Do not advertise DSSS/CCK support in 40 MHz for 5 GHz band
