2ce12789c1 Add Diffie-Hellman group definitions for MODP groups in RFC 5114
The groups 22, 23, and 24 are not based on a safe prime and generate a
prime order subgroup. As such, struct dh_group is also extended to
include the order for previously defined groups (q=(p-1)/2 since these
were based on a safe prime).

6917c9e829 Allow AP mode deauth/disassoc reason code to be overridden
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.

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.

The config says that the default for ap_table_max_size is 255 and the
default for ap_table_expiration_time is 60. But the code doesn't reflect
the default values mentioned in the sample config file.

These variables completely disable the code for Overlapping Legacy BSS
Condition by default when they are not correctly initialized. WFA
certification requires this feature and therefore an AP would have
failed the certification process unless they were initialized manually
using the configuration file.

6aaac006af PMKSA: Make deauthentication due to cache entry removal more granular
Expiry can always trigger a deauthentication, but otherwise,
deauthentication should only happen when the *current* cache entry is
removed and not being replaced. It should not happen when the current
PMK just happens to match the PMK of the entry being removed, since
multiple entries can have the same PMK when OKC is used and these
entries are often removed at different times.

This fixes an issue where eviction of the oldest inactive entry due to
adding a newer entry to a full cache caused a deauthentication when the
entry being removed had the same PMK as the current entry.

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.

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

By this sequence, pbkdf2_sha1() was called three times and the function
calculates the same value each time. Reduce number of calls to
pbkdf2_sha1() from 3 to 1 by caching the previous result.

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.

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.

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.

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

addressing them by reallocating the buffer (i.e., ignoring TLS Message

586c446e0f EAP-TLS server: Fix TLS Message Length validation
EAP-TLS/PEAP/TTLS/FAST server implementation did not validate TLS
Message Length value properly and could end up trying to store more
information into the message buffer than the allocated size if the first
fragment is longer than the indicated size. This could result in hostapd
process terminating in wpabuf length validation. Fix this by rejecting
messages that have invalid TLS Message Length value.

This would affect cases that use the internal EAP authentication server
in hostapd either directly with IEEE 802.1X or when using hostapd as a
RADIUS authentication server and when receiving an incorrectly
constructed EAP-TLS message. Cases where hostapd uses an external
authentication are not affected.

its GO role (i.e., if it receives an Invitation Request, it will reply
in P2P Device role). As such, this fix does not really change any

02a0ce13bc EAP-AKA server: Require AKA/Identity response to include identity
Since we always request an identity in the request, the response
has to include AT_IDENTITY. This allows the AKA/Identity response

b4569a3bd8 EAP-AKA server: Use simpler AKA/Identity request determination
There is no need to use eap_sim_db_identity_known() here since a new
AKA/Identity message is built only if the identity in the previous
response was not recognized. The first round is always used to request
AT_ANY_ID_REQ to meet the RFC 4187 recommendation on EAP method specific
identity request.

This commit adds control interface commands and internal storage of
Wi-Fi Display related configuration. In addition, WFD IE is now added
to various P2P frames, Probe Request/Response, and (Re)Association
Request/Response frames. WFD subelements from peers are stored in the
P2P peer table.

Following control interface commands are now available:
SET wifi_display <0/1>
GET wifi_display
WFD_SUBELEM_SET <subelem> [hexdump of length+body]
WFD_SUBELEM_GET <subelem>

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.
