Some deployed authentication servers seem to be unable to handle the TLS
Session Ticket extension (they are supposed to ignore unrecognized TLS
extensions, but end up rejecting the ClientHello instead). As a
workaround, disable use of TLS Sesson Ticket extension for EAP-TLS,
EAP-PEAP, and EAP-TTLS (EAP-FAST uses session ticket, so any server that
supports EAP-FAST does not need this workaround).

tls_disable_session_ticket=1 in phase1/phase2 can now be used to disable
use of TLS Session Ticket extension (which is enabled by default in
recent OpenSSL versions). This can be used to work around issues with
broken authentication servers that do not ignore unrecognized TLS
extensions properly.

If bgscan is enabled, then bgscan is initiated after the connection,
with no bss scan result information. Since a scan was performed prior to
the connection, the information exists and can be used to initialize the
bgscan's cache.

WSC 2.0 deprecates use of WPA (TKIP) and does not allow WPA/TKIP only
configuration (i.e., WPA2/CCMP needs to be enabled in mixed mode for
WPA/TKIP to be acceptable). Enforce this by disabling WPS if
configuration enables WPA/TKIP without WPA2/CCMP.

Use SSL_export_keying_material() if possible, i.e., if OpenSSL is
version 1.0.1 or newer and if client random value is used first. This

without exporting the master key from OpenSSL.

GAS_QUERY_TIMEOUT value was used for two different things - enum for
status callback and #define for internal eloop timeout). The latter
overwrites the former and as such, the timeout reported ended up going
out with value 5 which matches with GAS_QUERY_CANCELLED instead of
GAS_QUERY_TIMEOUT. This value was not used in existing code, so this
should not modify the current behavior. Anyway, the correct reason for
the failure should be reported. Rename the internal #define for the
timeout period to avoid the name conflict. [Bug 463]

This function can be used as a wrapper for os_realloc(ptr, nmemb * size)
when a reallocation is used for an array. The main benefit over
os_realloc() is in having an extra check to catch integer overflows in
multiplication. This is similar to the os_zalloc() to os_calloc() move.

There is no need to mandate admission control (ACM=1) by default, so
clear that flag in the case the configuration file does not specify
wmm_ac_{vo,vi}_acm value. This gets closer to the values mentioned
in the sample hostapd.conf file and reduces the need to specify WMM
parameters in the configuration file for most common use cases.

In case of P2P GO and AP mode, wpa_supplicant uses the default hostapd
parameters for WMM. In the default parameters the ACM bit for video and
voice are set to 1, meaning, P2P devices and stations which are
connected to the GO cannot pass voice or video data packets. Allow this
to be changed through wpa_supplicant configuration file with wmm_ac_*
parameters.

p2p_set_timeout() calls in GO Neg Req/Resp TX callbacks used timeout of
100 ms which is the value given in the P2P specification for GO
Negotiation, but this was actually shorter than the
wait-for-offchannel-TX value (200 ms) used for the driver call. In
addition, it looks like some devices (e.g., Galaxy Nexus with JB image)
can take longer time to reply to GO Negotiation Response (somewhere
between 200 and 250 ms has been observed).
Increase the wait-for-GO-Neg-Resp timeout from 100 ms to 200 ms if GO
Negotiation Request frame was acknowledged (this matches with the
offchannel wait timeout that used previously). The no-ack case is left
at 100 ms since we use GO Negotiation Request frame also to discover
whether the peer is on its Listen channel.
Increase the wait-for-GO-Neg-Conf timeout from 100 ms to 250 ms (and
increase the offchannel wait timeout to matching 250 ms) as a workaround
for devices that take over 200 ms to reply to GO Negotiation Response.

This is the normal flow for association:
wpa_supplicant <--(EVENT_ASSOC event )-- device driver
wpa_supplicant --( get_bssid() )--> device driver
wpa_supplicant <--( return BSSID )-- device driver
However, a device driver could return EINVAL for get_bssid() because it
recognizes it has already been disconnected. When the wpa_supplicant
received EINVAL, the bssid field could be used uninitialized in the
following flow:
wpa_supplicant <--(EVENT_ASSOC event )-- device driver
device driver (receive deauth)
wpa_supplicant --( get_bssid() )--> device driver
wpa_supplicant <--( return EINVAL )-- device driver
Prevent this by requiring the get_bssid() call to succeed when
processing association events.
