The cookie values for UDP control interface commands was defined as a

hapd2 = hostapd.add_bss(apdev[0], ifname2, 'bss-2.conf')
hapd1->ping() did not work.

hapd_interfaces and struct hostapd_data to fix this.

Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken

to leaking clear text MPDUs.

Previously only couple of AKM suite selectors were converted into
NL80211_ATTR_AKM_SUITES. Add rest of the AKM suites here. However, since
the current kernel interface has a very small limit
(NL80211_MAX_NR_AKM_SUITES = 2), add the attribute only when no more
than that limit entries are included. cfg80211 would reject the command
with any more entries listed.
This needs to be extended in cfg80211/nl80211 in a backwards compatible
manner, so this seems to be the best that can be done for now in user
space. Many drivers do not use this attribute, so must not reject the
configuration completely when larger number of AKM suites is configured.
Such cases may not work properly with drivers that depend on
NL80211_ATTR_AKM_SUITES value.

SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.

Now that hostapd wpa_psk_file has a new tag for identifying PSKs that

provisioning again.
Signed-off-by: Jouni Malinen <j@w1.fi>
By default, when configuration file set wpa_psk_file, hostapd generated
a random PSK for each Enrollee provisioned using WPS and appended that
PSK to wpa_psk_file.
Changes that behavior by adding a new step. WPS will first try to use a
PSK from wpa_psk_file. It will only try PSKs with wps=1 tag.
Additionally it'll try to match enrollee's MAC address (if provided). If
it fails to find an appropriate PSK, it falls back to generating a new
PSK.

A driver supports FT if it either supports SME or the

of those conditions are met. This can cause association failures, e.g.,
when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
the driver doesn't support it). This change allows an FT suite to be

Only one peer-commit-scalar value was stored for a specific STA (i.e.,
one per MAC address) and that value got replaced when the next SAE
Authentication exchange was started. This ended up breaking the check
against re-use of peer-commit-scalar from an Accepted instance when
anti-clogging token was requested. The first SAE commit message (the one
without anti-clogging token) ended up overwriting the cached
peer-commit-scalar value while leaving that instance in Accepted state.
The second SAE commit message (with anti-clogging token) added ended up
getting rejected if it used the same value again (and re-use is expected
in this particular case where the value was not used in Accepted
instance).
Fix this by using a separate pointer for storing the peer-commit-scalar
value that was used in an Accepted instance. There is no need to
allocate memory for two values, i.e., it is sufficient to maintain
separate pointers to the value and move the stored value to the special
Accepted state pointer when moving to the Accepted state.
This fixes issues where a peer STA ends up running back-to-back SAE
authentication within couple of seconds, i.e., without hostapd timing
out the STA entry for a case where anti-clogging token is required.
