scard_gsm_auth() used SIM_CMD_GET_RESPONSE for both SIM and USIM. Convert
the command into USIM_CMD_GET_RESPONSE for USIM.
Since commit eb32460029 ("Fix switching from EAP-SIM to EAP-AKA/AKA'")
EAP-SIM is using the USIM if available. This triggers a probably ancient
bug in scard_gsm_auth(), which results in sending the wrong get response
command to the USIM. Thus, EAP-SIM stopped to work after this change on
USIMs that expect the proper command.

Peer should handle a GO Negotiation exchange correctly when the
responding device does not have WSC credentials available at the
time of receiving the GO Negotiation Request. WSC Credentials
(e.g., Pushbutton) can be entered within the 120 second timeout.
Presently, if concurrent session is not active, the peer would wait for
GO Negotiation Request frame from the other device for approximately one
minute due to the earlier optimization change in commit
a2d6365760. To meet the two minute
requirement, replace this design based on number of iterations with a
more appropriate wait for the required number of seconds.

bss->freq was not updated for IBSS, so whatever old value was stored
from a previous AP mode operation could end up having been used as the
channel when trying to send Authentication frames in an RSN IBSS. This
resulted in the frame not sent (cfg80211 rejects it) and potentially not
being able to re-establish connection due to 4-way handshake failing
with replay counter mismatches. Fix this by learning the operating
channel of the IBSS both when join event is received and when a
management frame is being transmitted since the IBSS may have changed
channels due to merges.

The extra data (nonce_s) used in this message was pointing to the

Some OpenSSL versions have vulnerability in TLS heartbeat request
processing. Check the processed message to determine if the attack has
been used and if so, do not send the response to the peer. This does not
prevent the buffer read overflow within OpenSSL, but this prevents the
attacker from receiving the information.
This change is an additional layer of protection if some yet to be
identified paths were to expose this OpenSSL vulnerability. However, the
way OpenSSL is used for EAP-TLS/TTLS/PEAP/FAST in hostapd/wpa_supplicant
was already rejecting the messages before the response goes out and as
