Jouni Malinen 8b706a99b8 nl80211: Add MFP information for NL80211_CMD_CONNECT
This was previously included only with NL80211_CMD_ASSOCIATE, but the
information is as useful (if not even more useful) for
NL80211_CMD_CONNECT. It should be noted that cfg80211 does not yet use
this attribute with NL80211_CMD_CONNECT, but that can be added easily.

Sunil Dutt 624b4d5a64 P2P: Use the same Dialog Token value for every GO Negotiation retry
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 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.

Sunil Dutt c0810ddb3c P2P: Use the same Dialog Token value for every PD retry
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.

Arik Nemtsov 50285f5ca8 P2P: Always re-select operating channel if not hard coded
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

Fix this by updating the device entry only if the new peer entry is

Jouni Malinen 175171ac6c P2P: Retry PD Request in join-a-running-group case
The GO may be in sleep when we send a PD Request frame to indicate that
we are about to join a running group. Previously, this frame was not
retried more than normal low level retries. This can result in the GO
not getting the frame especially in cases where concurrent multi-channel
operations or aggressive sleep schedule is used since most drivers do
not yet synchronize with the GO's NoA before association.

Increase the likelihood of the GO receiving the PD Request frame by
retransmitting it similarly to the PD-for-GO-Negotiation case. Start
the actual join operation only after these retries have failed to get
an acknowledgment from the GO to give the connection attempt a chance
to succeed if the driver implements better NoA synchronization for it.

Christopher Wiley a8c5b43ad3 nl80211: Roam correctly through cfg80211 without SME
Change the nl80211 driver in wpa_supplicant to correctly handle
connecting to a new AP through cfg80211 without SME capability. As
before, the driver will disconnect from the previously associated AP,
but now we attempt to immediately connect to our intended AP. This
prevents us from blacklisting the AP we were trying to connect to
because of a semantic mismatch between cfg80211 and wpa_supplicant. The
disconnect/connect patch generates a local disconnect nl80211 event
which we discard because we're already correctly tracking the pending
association request.

In detail:

cfg80211 does not support connecting to a new BSS while already
connected to another BSS, if the underlying driver doesn't support
separate authenticate and associate commands. wpa_supplicant is written
to expect that this is a supported operation, except for a little error
handling that disconnects from the current BSS when roaming fails and
relies on autoconnect logic to reconnect later. However, this failure to
connect is incorrectly attributed to the new AP we attempted to
associate with, rather than a local condition in cfg80211.

The combined effect of these two conditions is that full-mac drivers
accessible through cfg80211 but without SME capability take a long time
to roam across BSS's because wpa_supplicant will:
1) Fail to associate for local reasons
2) Disconnect and return that the association request failed
3) Blacklist the association target (incorrectly)
4) Do a scan
5) Pick a less desirable AP to associate with

Jouni Malinen 3da372fae8 Use deauthentication instead of disassociation on RSN element mismatch
Even though the standard currently describes disassociation to be used
for RSN element mismatch between Beacon/Probe Response frames and
EAPOL-Key msg 3/4, this is unnecessary difference from other cases that
deauthenticate. In addition, there is no point in leaving the 802.11
Authentication in place in this case. To keep things simpler, use
deauthentication here to get rid of the only use of
wpa_sm_disassociate().

Jouni Malinen b363121a20 WPS: Reject invalid credential more cleanly
If WPS Registrar tries to provision a WPA/WPA2-Personal network without
including a valid Network Key, the network block cannot be used to
connect to the network. Reject such credential without adding the
network block. This makes wpa_supplicant send WSC_NACK as a response to
the invalid Credential and stop the provisioning process immediately
rather than only after trying unsuccessfully to connect to the network.

Jouni Malinen 96beff11d1 P2P: Allow discoverable interval for p2p_find to be configured
The new P2P_SET parameter disc_int can now be used to configure
discoverable interval for p2p_find operations. The format of the command
for setting the values is "P2P_SET disc_int <minDiscoverableInterval>
<maxDiscoverableInterval> <max TUs for discoverable interval>". The
first two parameters are given in units of 100 TUs (102.4 ms). The third
parameter can be used to further limit the interval into a specific TU
amount. If it is set to -1, no such additional limitation is enforced.
It should be noted that the P2P specification describes the random
Listen state interval to be in units of 100 TUs, so setting the max TU
value to anything else than -1 is not compliant with the specification
and should not be used in normal cases. The default parameters can be
set with "P2P_SET disc_int 1 3 -1".

Jouni Malinen 86cf382b80 Fix EAPOL supplicant port authorization with PMKSA caching
The previous eapol_sm_notify_cached() implementation forced the port
to be authorized when receiving EAPOL-Key msg 1/4 that included a
matching PMKID in cases when PMKSA caching is used. This is too early
since the port should really be authorized only after the PTK has been
configured which is the case when PMKSA caching is not used.

Fix this by using the EAPOL supplicant PAE state machine to go through
the AUTHENTICATING and AUTHENTICATED states instead of forcing a jump
to AUTHENTICATED without performing full state machine steps. This can
be achieved simply by marking eapSuccess TRUE at least with the current
version of EAP and EAPOL state machines (the earlier commits in this
function seemed to indicate that this may have not been that easy in
the older versions due to the hacks needed here).

This addresses an issue with nl80211-based driver interface when the
driver depends on the STA Authorized flag being used to prevent
unprotected frames from being accepted (both TX and RX) prior to PTK
configuration.

David Bird f826635c2d Fix EAPOL processing when STA switches between multi-BSSes
There was an issue with EAPOL frame exchanges in a multi-BSS
configuration when a station switches between the BSSes controlled by
the same hostapd process. When processing the EAPOL packet, the array of
virtual APs (iface->bss) is searched looking for the station that sent
the packet in order to identify which signal context should be used
during processing. The first match of the station in its list gets used
in the ieee802_1x_receive() function. However, even after a station has
disassociated, it remains in the list of stations pending an inactivity
timeout. This leads to the wrong hapd context (one where the station had
already disassociated) being used in some cases (if the current/active
bss entry appears in the list after one where the station has just
disassociated from) for EAPOL processing.

Fix this by checking the WLAN_STA_ASSOC flag before assuming the right
hapd context was found for the given station.

Jouni Malinen 13ece96f70 P2P: Improve robustness against lost ctrl::ack frames
P2P includes two use cases where one of the devices is going to start a
group and likely change channels immediately after processing a frame.
This operation may be fast enough to make the device leave the current
channel before the peer has completed layer 2 retransmission of the
frame in case the ctrl::ack frame was lost. This can result in the peer
not getting TX status success notification.

For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround
that ignores the TX status failure and will continue with the group
formation with the assumption that the peer actually received the frame
even though we did not receive ctrl::ack. For Invitation Response frame
to re-invoke a persistent group, no such workaround is used in
p2p_invitation_resp_cb(). Consequently, TX status failure due to lost
ctrl::ack frame results in one of the peers not starting the group.

Increase the likelihood of layer 2 retransmission getting acknowledged
and ctrl::ack being received by waiting a short duration after having
processed the GO Negotiation Confirm and Invitation Response frames for
the re-invocation case. For the former, use 20 ms wait since this case
has been worked around in deployed devices. For the latter, use 50 ms
wait to get even higher likelihood of getting ctrl::ack through since
deployed devices (and the current wpa_supplicant implementation) do not
have a workaround to ignore TX status failure.

20 ms is long enough to include at least couple of retries and that
should increase likelihood of getting ctrl::ack through quite a bit. The
longer 50 ms wait is likely to include full set of layer 2 retries.

Previously, WPS Registrar allowed multiple wildcard PINs to be

Enrollee that does not have a specific PIN and as such, cannot really be
used with different PIN values in reasonable ways. To avoid confusion
with multiple enabled PINs, invalidate any previously configured

While the existing code already addresses TLS Message Length validation
for both EAP-TLS peer and server side, this adds explicit checks and
rejection of invalid messages in the functions handling reassembly. This
does not change externally observable behavior in case of EAP server.
For EAP peer, this starts rejecting invalid messages instead of
addressing them by reallocating the buffer (i.e., ignoring TLS Message
Length in practice).
