Each GO Negotiation Request is (re)tried with an unique dialog token and
a GO Negotiation Response / Confirmation from the peer with a mismatched
dialog token is ignored which could result in a failure in this group
formation attempt. Thus, the P2P device would continue retrying the GO
Negotiation Request frames till the GO Negotiation Response frame with a
matching dialog token is received. To avoid the failures due to the
dialog token mismatch in retry cases if the peer is too slow to reply
within the timeout, the same dialog token value is used for every retry
in the same group formation handshake.
It should be noted that this can result in different contents of the GO
Negotiation Request frame being sent with the same dialog token value
since the tie breaker bit in GO Intent is still toggled for each
attempt. The specification is not very clear on what would be the
correct behavior here. Tie breaker bit is not updated on
"retransmissions", but that is more likely referring to the layer 2
retransmission and not the retry at higher layer using a new MMPDU.

The groups 22, 23, and 24 are not based on a safe prime and generate a

This allows FFC groups to be used with SAE. Though, these groups are not

The optional "reason=<reason code>" parameter to the ctrl_iface
deauthenticate and disassociate commands can now be used to change the
reason code used in the disconnection frame. This can be used, e.g., by
P2P GO to disconnect a single P2P client from the group by sending it an
indication of the group getting terminated (Deauthentication frame with
reason code 3). It needs to be noted that the peer device is still in
possession on the PSK, so it can still reconnect to the group after this
if it does not follow the group termination indication.

Commit 175171ac6c ensured that the PD
requests are retried in join-a-running group case and the Enrollee is
started on either receiving the PD response or after the retries. Each
PD request is retried with an unique dialog token and a PD response from
the GO with a mismatched dialog token is ignored. Thus, the P2P client
would continue retrying the PD requests till the response with a
matching dialog token is obtained. This would result in the GO getting
multiple PD requests and a corresponding user notification (POP UP) in
implementations where each PD request results in a POP UP, resulting in
a bad user experience. To avoid such behavior, the same dialog token
value is used for every retry in the same PD exchange.

This makes it easier to read the code for the two possible cases
(forced/preferred channel and automatic channel selection).
Signed-hostap: Jouni Malinen <j@w1.fi>
Since the operating channel is randomly set to 1/6/11 on init, which is
commonly included in the channel intersection, we were effectively
ignoring the set of P2P preferred channels when trying to improve
channel selection after having received peer information. Fix this by
trying to get the best channel we can, unless the user hard coded the
operating channel in the configuration file or p2p_connect command. Fall
back to the initial randomly selected channel if a better one cannot be
chosen.

cfg80211 caches the scan results according the channel number. Due to
