29fbc52251 Fix AP selection to check privacy mismatch and IBSS with WPA/RSN IE
These checks were previously skipped if the scan result included WPA
or RSN IE. However, that can result in selecting a network that does
not match local configuration in some cases.

9e2704c3a2 Add EVENT_RX_ACTION handler for hostapd
This fixes an issue with SA Query Response frames not being processed
anymore after wpa_supplicant started registering a handler for those.
This handler registration is in generic driver_nl80211.c code, so
hostapd uses it, too.

7dcdcfd68d P2P: Start GO without extra scan step
There are some corner cases, where the wpa_supplicant_req_scan() call
may end up scheduling a scan even if we are about to start a GO. Avoid
this by explicitly marking the GO network to be selected for the next
connection.

a6efc65ddb nl80211: Add support for driver-based PMKSA cache
Implement PMKSA cache operations add, remove, and flush using nl80211
commands NL80211_CMD_{SET,DEL,FLUSH}_PMKSA to support PMKSA caching
with drivers that select the AP and generate the RSN IE internally.

911e97e400 DBus: Refactor array adding, add binary arrays
Some new code we're working on will require the dbus type "aay" (an
array of arrays of bytes). To add this, refactor the array code to
reduce code duplication by given a type string to the array starting
code, and also add code to create and parse such arrays from or into an
array of struct wpabuf respectively.

Since there's no unique DBus type for this, add a "fake"
WPAS_DBUS_TYPE_BINARRAY type that is separate from the regular DBus
types for parsing.

6b56cc2d97 P2P: Retry provision discovery requests in IDLE state
Since the peer may not be in Listen state when the provision discovery
request is sent, try to send the request again number of times when in
IDLE state. This was already done when p2p_find is in progress, but this
commit adds retries to the case where no other P2P operations are in
progress.

38e24575c1 random: Add support for maintaining internal entropy store over restarts
This can be used to avoid rejection of first two 4-way handshakes every
time hostapd (or wpa_supplicant in AP/IBSS mode) is restarted. A new
command line parameter, -e, can now be used to specify an entropy file
that will be used to maintain the needed state.

6d28fb9627 Fix regression in RSN pre-authentication candidate list generation
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.

fa5165586f WPS: Add a workaround for Windows 7 capability discovery for PBC
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).

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.

b8281964af Add workaround for race condition with AssocResp TX status
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.
