The new hostapd configuration parameter anqp_elem can now be used to
configure arbitrary ANQP-elements for the GAS/ANQP server. In addition
to supporting new elements, this can be used to override previously
supported elements if some special values are needed (mainly for testing
purposes).
The parameter uses following format:
anqp_elem=<InfoID>:<hexdump of payload>
For example, AP Geospatial Location ANQP-element with unknown location:
anqp_elem=265:0000
and AP Civic Location ANQP-element with unknown location:
anqp_elem=266:000000

The switch to BoringSSL broke keystore-backed keys because
wpa_supplicant was using the dynamic ENGINE loading to load
the keystore module.
The ENGINE-like functionality in BoringSSL is much simpler
and this change should enable it.

Some devices cannot respond to inactive client probe (empty data frame)
within one second. For example, iPhone may take up to 3 secs. This
becomes a significant problem when ap_max_inactivity is set to lower
value such as 10 secs. iPhone can lose Wi-Fi connection after ~1 min
of user inactivity.

On RADIUS auth/acct failures hostapd will try a new server if one is
available. Reuse the failover logic to force a socket renewal if only
one RADIUS server is configured.
This fixes problems when a route for the RADIUS server gets added after
the socket was "connected". The RADIUS socket is still sending the
RADIUS requests out using the previous route.

IEEE Std 802.11-2012 13.3.1 states that the AID should be generated on
the local node for each peer. Previously, we were using the peer link ID
(generated by the peer) which may not be unique among all peers. Correct
this by reusing the AP AID generation code.

This ensures that group key is set as long as the interface exists.
Additionally, ifconfig_up is needed as wpa_group will enter
FATAL_FAILURE if the interface is still down. Also vlan_remove_dynamic()
is moved after wpa_auth_sta_deinit() so vlan_remove_dynamic() can check
it was the last user of the wpa_group.

The CSA channel and operating class values need to be set for all types
of channel switch (i.e., either if it's triggered by the control

that sets them from the GO-follows-STA flow to the more generic
hostapd_fill_csa_settings() function.

The hostapd_hw_get_channel() function can't be used to convert center
frequencies to channel numbers, because the hw mode lists don't have all
the center frequencies. The hw mode lists have the main channel
frequencies and flags to indicate the channel topography.
For instance, channel 5805 with VHT80- has the channel center frequency
segment 0 at 5775. This segment is only indicated indirectly in the hw
mode list by the HOSTAPD_CHAN_VHT_50_30 flag. The hw mode list doesn't
have any elements with frequency 5775 to allow the conversion to a
channel number. Thus, we need to use ieee80211_freq_to_chan() instead.

Commit 7d711541dc ('Clear TK part of PTK
after driver key configuration') started clearing TK from memory
immediately after having configured it to the driver when processing
EAPOL-Key message 3/4. While this covered the most common case, it did
not take into account the possibility of the authenticator having to
retry EAPOL-Key message 3/4 in case the first EAPOL-Key message 4/4
response is lost. That case ended up trying to reinstall the same TK to
the driver, but the key was not available anymore.
Fix the EAPOL-Key message 3/4 retry case by configuring TK to the driver
only once. There was no need to try to set the same key after each
EAPOL-Key message 3/4 since TK could not change. If actual PTK rekeying
is used, the new TK will be configured once when processing the new
EAPOL-Key message 3/4 for the first time.

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.
