code to use this in wpa_supplicant (i.e, hostapd DPP implementation does
not yet support PKEX).

ERP key was previously derived immediately after the availability of

wpa_supplicant can now be configured to generate a network profile
automatically based on DPP configuration. The following
dpp_config_processing values can be used to specify the behavior:
0 = report received configuration to an external program for
processing; do not generate any network profile internally (default)
1 = report received configuration to an external program and generate
a network profile internally, but do not automatically connect
to the created (disabled) profile; the network profile id is
reported to external programs
2 = report received configuration to an external program, generate
a network profile internally, try to connect to the created
profile automatically

Commit 5538fc9309 ('FILS: Track completion
with FILS shared key authentication offload') added an additional case
for calling wpa_supplicant_event_assoc_auth() from EVENT_ASSOC handling
in case of FILS-completion with driver-based-SME. However, that checked
what placed outside the data != NULL case while data != NULL needs to
apply for this case as well due to wpa_supplicant_event_assoc_auth()
behavior. Move the data != NULL check to apply to both cases to avoid
potentially issues if a driver interface were to return EVENT_ASSOC
without the associate data. (CID 164708)

While encoded == NULL could happen in the case of an empty blob, that
will result in encoded_len == 0 and base64_decode() not derefencing the
src argument. That seems to be too difficult for some static analyzers,
so to avoid false warnings, explicitly reject the encoded == NULL case
without even trying to base64 decode it. (CID 164709)

This new AKM is used with DPP when using the signed Connector to derive

Add wpa_supplicant control interface commands for parsing the bootstrap
info URI from a QR Code (get peer public key) and to generate a new
bootstrap info with private key for local use. The optional
key=<hexdump> argument to the DPP_BOOTSTRAP_GEN command can be used to
specify the bootstrapping private key in OpenSSL ECPrivateKey DER
encoding format. This results in the local bootstrapping information
entry being created with the specified key instead of generating a new
random one.

There could be multiple pending TX operations and if the earlier ones
have used wait_time, but the last one did not, the driver call for
canceling pending wait was not done. This could result in the driver
getting stuck waiting for the previously scheduled wait time and not
being able to do new operations until that. Fix this by canceling the
wait if any of the past offchannel_send_action() calls since the last
offchannel_send_action_done() used non-zero wait_time.
This was showing up as issues in certain DPP Public Action frame
sequences when the same offchannel operation is used with multiple
frames and the last frame in the sequence does not need wait_time.

wpa_s->p2p_in_provisioning needs to be cleared when group formation
fully completes. The change to postpone GO side handling to the first
data connection in commit 41f853235f
('P2P: Extend group formation timeout on GO to first data connection')
resulted in making this not happen in one P2P Client side case: EAP-WSC
timeout in PBC case. While that is quite special case since it requires
30 second timeout without receiving new EAPOL frames and not getting
disassociation, it can apparently happen in some cases in practice. This
would result in new P2P operations (e.g., P2P_FIND) getting rejected
until wpa_supplicant is restarted.
Fix this by clearing wpa_s->p2p_in_provisioning whenever processing a
group formation failure case. For group formation success,
wpa_s->p2p_in_provisioning is left set to non-zero value to avoid
breaking the earlier limits on the GO side.

For proxy based EAP methods, the EAP identity is constructed in

wpa_supplicant tries to reinitialize an interface when a previously
removed netdev is restored (e.g., re-insert a USB dongle). If that
initialization fails (e.g., driver ejects ifconfig UP), the previous
implementation resulted in leaving the interface in incomplete state
while still claiming to upper layers that the interface status has
changed back to functional one.
Fix this by skipping the interface status update if reinitialization
fails. In other words, remain in INTERFACE_DISABLED state if the
interface cannot be re-enabled successfully.

hostapd processes a received 20/40 BSS Coexistence management frame, but
if no separate callbacks are registered for handling Public Action
frames it eventually sends a reply with MSB of category code set to 1
thinking that the received frame is an invalid frame. This could happen
based on whether hostapd was built and enabled with functionality using
the callback functions.
Fix this by explicitly returning 1 from the function when the 20/40 BSS
Coexistence Management frame is processed.
