Commit 7139cf4a4f ('P2P: Decrement
sd_pending_bcast_queries when sd returns success') added support for

Commit 7139cf4a4f ('P2P: Decrement
sd_pending_bcast_queries when sd returns success') changed P2P SD
behavior in a way that the P2P search loop ended up in continuing with
the first peer entry until it acknowledged receipt of a pending
broadcast SD request while the previous design went through all peers
once. While it is reasonable to retry SD, getting stuck with the first
peer is not really desirable. Change the p2p_continue_find() loop to
continue from the next peer in each iteration to allow progress through
all peers that have pending operations if any other peer is not
acknowledging frames (e.g., due to not being on Listen channel).

If a TX status event and RX event for a GO Negotiation frame gets
delayed long enough to miss the initial wait, it was possible for
reception of a GO Negotiation Response frame with status 1 to try to
initiate a new p2p-listen work item to wait for the peer to become ready
while a previous p2p-listen was already in progress due to that earlier
timeout while waiting for peer. This would result in the new
start_listen request getting rejected ("P2P: Reject start_listen since
p2p_listen_work already exists") and the negotiation not proceeding.

Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.
Reduce the default startWhen value from 3 to 2 seconds for non-WPS case
since WPS builds have likely received most testing for the past years
with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else
require the EAPOL-Start to initiate operation after a connection.

The internal entropy pool was previously used to prevent 4-way handshake
in AP mode from completing before sufficient entropy was available to
allow secure keys to be generated. This commit extends that workaround
for boards that do not provide secure OS level PRNG (e.g., /dev/urandom
does not get enough entropy) for the most critical WPS operations by
rejecting AP-as-enrollee case (use of AP PIN to learn/modify AP
configuration) and new PSK/passphrase generation. This does not have any
effect on devices that have an appropriately working OS level PRNG
(e.g., /dev/random and /dev/urandom on Linux).

This forces EAP peer implementation to drop any possible fast resumption
data if the network block for the current connection is not the same as
the one used for the previous one. This allows different network blocks
to be used with non-matching parameters to enforce different rules even
if the same authentication server is used. For example, this allows
different CA trust rules to be enforced with different ca_cert
parameters which can prevent EAP-TTLS Phase 2 from being used based on

FreeRADIUS releases before 1.1.4 did not send MS-CHAP2-Success in
EAP-TTLS/MSCHAPv2. A wpa_supplicant workaround for that was added in
2005 and it has been enabled by default to avoid interoperability
issues. This could be disabled with all other EAP workarounds
(eap_workaround=0). However, that will disable some workarounds that are
still needed with number of authentication servers.
Old FreeRADIUS versions should not be in use anymore, so it makes sense
to remove this EAP-TTLS/MSCHAPv2 workaround completely to get more
complete validation of server behavior. This allows MSCHAPv2 to verify
that the server knows the password instead of relying only on the TLS
certificate validation.

1 = Probe Response frame from P2P Device role
2 = Probe Response frame from P2P GO
3 = Beacon frame from P2P GO
