Srinivas Dasari d74963d411 DPP: Extend dpp_test 89 functionality to transmit side
This extends dpp_test functionality to allow DPP exchanges to be stopped
after authentication is completed on the Initiator, i.e., after sending
out the Authentication Confirm message. Previously, dpp_test=89 was used
only on the Responder side to stop after receiving the Authentication
Confirm message. The main use case for this extended functionality is to
be able to stop the protocol exchange on a device that acts as
authentication Initiator and Enrollee.

Purushottam Kushwaha f8bfc9cbde Use correct WPA_ALG_* values to compare for enum wpa_alg
enum wpa_alg was being compared with WPA_CIPHER_* values. That does not
work here and strict compilers will report this as an error. Fix the
comparision to use proper WPA_ALG_* values. This fixes testing
capability for resetting IPN for BIP.

Extend ACL check to deny Probe Request frames for the client which does

Jouni Malinen f5e0a3324b SAE: Fix potential infinite loop in mismatching PMK case on AP
Commit e61fea6b46 ('SAE: Fix PMKSA caching
behavior in AP mode') modified the PSK fetching loop to not override PMK
in case of SAE with PMKSA caching. However, that commit missed the error
path cases where there is need to break from the loop with exact
negative of the check in the beginning of the loop. This could result in
hitting an infinite loop in hostapd if a station derived a different PMK
value from otherwise successfully completed SAE authentication or if a
STA used a different PMK with a PMKSA caching attempt after a previously
completed successful authentication.

Fix this by adding the matching break condition on SAE AKM within the
loops.
