On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.
Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.
Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.
As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill
context for the P2P Device interface. For nl80211, as the wiphy index
is known only after getting the driver capabilities from the kernel,
move the initialization of the rfkill object to
wpa_driver_nl80211_finish_drv_init().

This patch fixes an issue with an invalid phase2 parameter value
auth=MSCHAPv2 getting interpreted as auth=MSCHAP (v1) which could
degrade security (though, only within a protected TLS tunnel). Now when
invalid or unsupported auth= phase2 parameter combinations are
specified, EAP-TTLS initialization throws an error instead of silently
doing something.
More then one auth= phase2 type cannot be specified and also both auth= and
autheap= options cannot be specified.
Parsing phase2 type is case sensitive (as in other EAP parts), so phase2
parameter auth=MSCHAPv2 is invalid. Only auth=MSCHAPV2 is correct.

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

While this is not part of RFC 4137, the way m.check(eapReqData) is
implemented in wpa_supplicant allows an EAP method to not update the
ignore value even though each such call is really supposed to get a new
response. It seems to be possible to hit a sequence where a previous EAP
authentication attempt terminates with sm->ignore set from the last
m.check() call and the following EAP authentication attempt could fail
to go through the expected code path if it does not clear the ignore
flag. This is likely only hit in some error cases, though. The hwsim
test cases could trigger this with the following sequence:

When multiple interfaces across mutiple radios are started using a
single instance of hostapd, they all come up at different times
depending upon how long the ACS and HT scan take on each radio. This
will result in stations (that already have the AP profile) associating
with the first interfaces that comes up. For example in a dual band
radio case (2G and 5G) with ACS enabled, 2G always comes up first
because the ACS scan takes less time on 2G and this results in all
stations associating with the 2G interface first.
This feature brings up all the interfaces at the same time. The list of
interfaces specified via hostapd.conf files on the command line are all
marked as sync interfaces. All the interfaces are synchronized in
hostapd_setup_interface_complete().
This feature is turned on with '-S' commmand line option.

Linux packet socket workaround(*) has an impact in performance when the
workaround socket needs to be kept open to receive EAPOL frames. While
this is normally avoided with a kernel that has the issue addressed by
closing the workaround packet socket when detecting a frame through the
main socket, it is possible for that mechanism to not be sufficient,
e.g., when an open network connection (no EAPOL frames) is used.
Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the
workaround. This build option is disabled by default and can be enabled
explicitly on distributions which have an older kernel or a fix for the
kernel regression.
Also remove the unused variable num_rx.

This improves robustness of GO Negotiation in special cases where GO
Negotiation Request frames from the peer may end up getting delivered
multiple times, e.g., due to interference and retransmitted frames not
getting properly filtered out in duplicate detection (which is something
that number of drivers do not implement for pre-associated state).
If we have already replied with GO Negotiation Response frame with
Status 1 (not yet ready), do not reply to another GO Negotiation Request
frame from the peer if we have already received authorization from the
user (P2P_CONNECT command) for group formation and have sent out our GO
Negotiation Request frame. This avoids a possible sequence where two
independent GO Negotiation instances could go through in parallel if the
MAC address based rule on avoiding duplicate negotiations is not able to
prevent the case. This can allow GO Negotiation to complete successfully

Add new GO frequency move policy. The P2P_GO_FREQ_MOVE_SCM_ECSA prefers
SCM if all the clients advertise eCSA support and the candidate
frequency is one of the group common frequencies.

Extended channel switch provides an ability to switch between operating
classes and is required for P2P Devices by the P2P specification when
switching in 5 GHz.
When the operating class is provided for channel switch, the AP/P2P GO
will use eCSA IE in addition to the regular CSA IE both on 2.4 GHz and 5
GHz bands.
Transitions between different hw_modes are not supported.

Channel switch may be performed using both CSA and eCSA IEs together.
This may happen, for example with a P2P GO on band A with legacy
clients. Extend driver API to support up to 2 CSA counters.
This patch also includes the required implementation for nl80211.

When building Beacon and Probe Response frames for the target channel,
consider bandwidth parameter for VHT channels. In addition, add support
for updating vht_oper_centr_freq_seg0_idx and
vht_oper_centr_freq_seg1_idx.

When switching to a VHT channel with width greater than 20 MHz, add Wide
Bandwidth Channel Switch element. This element is added in Beacon and
Probe Response frames inside Channel Switch Wrapper element.

When CSA is started, hostapd_change_config_freq() computes the channel
from the provided frequency. Use this stored channel to add CSA IE in
Beacon frames, instead of recomputing the channel each time.

All the other web_connection_parse_*() functions were already doing
this, so make the GET handler consistent as well.
