SAE authentication derives PMKID differently from the EAP cases. The
value comes from information exchanged during SAE authentication and
does not bind in the MAC addresses of the STAs. As such, the same PMKID
is used with different BSSIDs. Fix both the hostapd and wpa_supplicant
to use the previous PMKID as is for OKC instead of deriving a new PMKID
using an incorrect derivation method when using an SAE AKM.
This fixes use of opportunistic key caching with SAE.

If no Beacon or Probe Response frame has been seen in the capture, use
the IEs from EAPOL-Key msg 3/4 to set up BSS information.
Signed-off-by: Jouni Malinen <j@w1.fi>
The previous implementation tried to update STA IE information based on
EAPOL-Key msg 2/4 to be able to handle captures that do not include the
(Re)Association Request frame. This was not sufficient (OSEN was not
included) and was done too late (the parsed information is needed for
PMK-to-PTK derivation).
Move the IE update step to happen before trying to derive the PTK if no
(Re)Association Request frame has been seen.

Update grpform_pbc_overlap not to require PBC session overlap to be
detected since in this sequence a single BSSID is specified and other
APs can be ignored while checking for session overlap. Add other test
cases to explicitly check for the PBC session overlap detection in
non-P2P and P2P cases when the BSSID is specified.

While the WSC specification requires the Enrollee to stop PBC
provisioning if the scan sees multiple APs in active PBC mode, this is
problematic due to some deployed devices continuing to advertise PBC
mode for extended duration (or even permanently). Such an environment
will still need to prevent wildcard AP selection with PBC since an
incorrect device could be selected. However, if the Enrollee device has
been explicitly requested to connect to a specific AP based on its
BSSID, the other APs in scan results can be ignored without affecting
which AP would be selected (only the one matching the specified BSSID is
acceptable).
Start filtering scan results for PBC session overlap check based on the
locally specified constraint on the BSSID, if one is set. This allows
PBC to be used with "WPS_PBC <BSSID>" command in environment where
another AP device is claiming to be in active PBC mode while "WPS_PBC"
command will still continue to reject provisioning since the correct AP
cannot be selected.
This will also cover the P2P cases where P2P_CONNECT is used to start or
authorize GO Negotiation and joining-a-GO with a specific P2P GO
Interface Address (BSSID).

Replace the hardcoded /tmp filenames for generated ACL and BSS
configuration files with proper temporary files from tempfile.mkstemp()
to avoid conflicts with existing files or with parallel uses. Remove ACL
files from the local directory at the end of each test case. BSS files
are currently left behind, but can be cleaned up separately if needed
for non-VM testing (VM testing has those on ramdrive so they get dropped
automatically at the end) and for remote devices.

When this test case is ran in remote test environment, there could be

That breaks the check on SCAN_RESULTS output. Extend this to cover the

The cookie values for UDP control interface commands was defined as a
static global array. This did not allow multi-BSS test cases to be
executed with UDP control interface. For example, after
hapd1 = hostapd.add_bss(apdev[0], ifname1, 'bss-1.conf')
hapd2 = hostapd.add_bss(apdev[0], ifname2, 'bss-2.conf')
hapd1->ping() did not work.

hapd_interfaces and struct hostapd_data to fix this.

There does not seem to be a good reason for using the different IFACE=
prefix on the UDP control interface. This got added when the UDP
interface in wpa_supplicant was extended in commit f0e5d3b5c6
("wpa_supplicant: Share attach/detach/send UDP ctrl_iface functions")
and that was then extended to hostapd in commit e920805685 ("hostapd:
Extend global control interface notifications").
Replace the IFACE= prefix in UDP case with IFNAME= to be consistent with
the UNIX domain socket based control interface.
This fixes a problem when at least one test case fail (hapd_ctrl_sta)
when remote/udp used. This also fixes test_connectivity().

Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken
implementations and should be avoided when using or interacting with
one. The effects can be triggered by either end of the connection and
range from hardly noticeable disconnects over long connection freezes up
to leaking clear text MPDUs.
To allow affected users to mitigate the issues, add a new configuration
option "wpa_deny_ptk0_rekey" to replace all PTK0 rekeys with fast

The MBO PMF check for AP SME in the driver case was added into a
location that is skipped for WPS processing. That was not really the
correct place for this since the skip_wpa_check label was supposed to
remain immediately following the WPA checks. While this does not really
have much of a practical impact, move the check around so that the
skip_wpa_check label remains where it is supposed to be.

Split the IEs from WPA authenticator state machine into separately added
IEs so that the exact location between these and other elements can be
controlled. This fixes the location of MDE and RSNXE in Beacon and Probe
Response frames. In addition, this swaps the order of BSS Load and RM
Enabled Capabilities elements in Beacon frames to get them into the
correct order (which was already used for Probe Response frames).
Furthermore, this fixes the buffer end checks for couple of elements to
make the implementation more consistent (though, in practice, there is
no impact from this since the old size limit was smaller than needed,
but still sufficiently large to have room for these).
