.set_rate_sets is not defined for non-hostapd, which prevents
configuring basic_rates when working as P2P GO.

Processing of the scan results for RSN pre-authentication candidates
was moved to happen before the network was selected. This resulted in
all candidates being dropped due to no SSID having been configured.
Fix this by moving the processing to happen after the network has
been selected. Since the raw scan results are not available at that
point, use the BSS table instead of scan results to fetch the
information.
If the driver wrapper is setting up the interface up only at commit(),
UPnP initialization fails. Fix that by moving UPnP setup to happen after
the driver commit() call.
Windows 7 uses incorrect way of figuring out AP's WPS capabilities by
acting as a Registrar and using M1 from the AP. The config methods
attribute in that message is supposed to indicate only the configuration
method supported by the AP in Enrollee role, i.e., to add an external
Registrar. For that case, PBC shall not be used and as such, the
PushButton config method is removed from M1 by default. If pbc_in_m1=1
is included in the configuration file, the PushButton config method is
left in M1 (if included in config_methods parameter) to allow Windows 7
to use PBC instead of PIN (e.g., from a label in the AP).
When using the p2p_oper_reg_class configuration option instead of
p2p_group_add freq parameter, the operating class 124 was not
processed correctly. Include that class in the list of 5 GHz classes
for the p2p_oper_reg_class to resolve this.
cfg80211 maintains separate BSS table entries for APs if the same
BSSID,SSID pair is seen on multiple channels. wpa_supplicant does
not use frequency as a separate key in the BSS table, so filter out
duplicated entries. Prefer associated BSS entry in such a case in
order to get the correct frequency into the BSS table.
It may take some time for the TX status to be delivered for a
(Re)Association Response frame and if any Data frames are received
during that time, they may end up getting dropped as Class 3 frames in
not-associated state. This results in a Disassociation frame being sent
to the station and it assuming that the association has been lost.
Work around the issue by remembering that the (Re)Association Request
has already been accepted and skip the Deauth/Disassoc sending because
of the possible Class 3 frames before the TX status callback is
received.
Set all the interfaces.iface pointers to NULL after the allocation of
that memory block for cases those pointers are accessed during each of
the interfaces initialization process (hostapd_interface_init()). One
example for such case is during WPS initialization when the code tries
to fetch the uuid from each of the interfaces.

In theory, these calls could fail, but it is not really likely to
happen in practice in the use case here. Anyway, check that they do
not return an error before accepting the length of the file.
This function does not get called with in_data == NULL in practice, but
it seems to be at least partly prepared for that case, so better make it
consistent by handling the NULL value throughout the function.
Both the SA and IEs from the received Probe Request frames must be
included and the Probe Request RX callback functions may assume that
these are not NULL.
The change to use wpa_dbg() in wpa_sm_parse_own_wpa_ie() could result
in a NULL pointer dereference if the function were called when WPA
state machine has not been initialized. While this cannot really
happen in practice, it is better to be prepared for that since that
was the case before the wpa_dbg() change.
When comparing BSS table entries, handle empty concatenated
vendor-specific IE differently from completely missing IE. This
does not change anything for the only currently compared IE that
can be fragmented (WPS IE), but it is better to have the generic
code here ready for any possible new IE that could be used in
with zero-length data.
The size_t value here can be 64-bit and result in implicit sign
extension. In this particular case, that gets masked out by
host_to_be32(), so there is no practical difference, but it is better
to get rid of the 64-bit variable explicitly.
The supportedTypes parameter is a list of TNC_MessageType values
and the buffer to be copied should use size of TNC_MessageType, not
TNC_MessageTypeList. In practice, these are of same length on most
platforms, so this is not a critical issue, but anyway, the correct
type should be used.
This avoids reading past the end of the IE buffer should the FTIE
be too short. In addition, one debug hexdump was using uninitialized
pointer to the FTIE buffer, so fixed it to use the pointer from the
parse data.
Better make sure the address value included in the event message gets
cleared in case the GO Device Address is not known for some reason.
Previously, this could potentially have been some random data from
stack should we ever hit the case where wpa_s->current_ssid is not
set (which should not really happen in normal use cases).
AF_INET6 is not always enabled by default, so use AF_INET instead. In
addition, use the old fixed length, 2048, as a failover value if the
sysctl fails for any reason.
It is now possible to configure the the time in seconds that
wpa_supplicant waits before requesting a new scan after failing to find
a suitable network in scan results.

Commit 03d3f28a69 broke initialization of
EAPOL authenticator state machines since an error value from
wpa_auth_sta_key_mgmt() (-1) was not handled properly and the fixed
wpa_key_mgmt_wpa_psk() identified the value as a PSK-based AKM because
of all bits being set to 1. The special error value needs to handled
separately to avoid skipping EAPOL state machine initialization.
If WPA/WPA2 was enabled in the configuration, the non-WPA exception
could allow an incorrect AP to be selected from scan results. Do
not use the exception if WPA/WPA2 is enabled in configuration.
These can be used in some cases with a bitfield having multiple
AKMs enabled (e.g., WPA-PSK and WPA-PSK-SHA256). Address those
cases by checking whether any of the matching AKM are included.
When the SME is in the driver or cfg80211, the automatic selection
of auth_alg is done by leaving out the NL80211_ATTR_AUTH_TYPE
attribute from the NL80211_CMD_CONNECT command.
