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.

This commit increases the maximum buffer size for P2P Client Info

Use of two variables to track bounds checking seems to be a bit too much
for some static analyzers, so add an extra condition for buffer padding
to avoid incorrect warnings.

These verify that a proper pointer type is used and in addition, seems
to get rid of some false static analyzer warnings.

Even though this command is very unlikely to fail, in theory, it could
and the WPS connection would fail in such a case. Return more clearer
failure indication in such a case without even trying to start
reassociation.

The code initializing GMK Counter uses the group pointer value as extra
entropy and to distinguish different group instances. Some static
analyzers complain about the sizeof(pointer) with memcpy, so use a more
explicit type casting to make it more obvious what the code is doing.

hostapd.conf sae_groups parameter can now be used to limit the set of
groups that the AP allows for SAE. Similarly, sae_groups parameter is
wpa_supplicant.conf can be used to set the preferred order of groups. By
default, all implemented groups are enabled.

In addition to the trivial change in adding the new group ientifier,
this required changes to KDF and random number generation to support
cases where the length of the prime in bits is not a multiple of eight.
The binary presentation of the value needs to be shifted so that the
unused most significant bits are the zero padding rather than the extra
bits in the end of the array.

In addition to the mandatory group 19 (256-bit random ECP group) add

This makes the SAE implementation a bit simpler by not having to build

hostapd can now be configured to use anti-clogging mechanism based on
the new sae_anti_clogging_threshold parameter (which is
dot11RSNASAEAntiCloggingThreshold in the standard). The token is
generated using a temporary key and the peer station's MAC address.
wpa_supplicant will re-try SAE authentication with the token included if
commit message is rejected with a token request.

The PMKSA cache expiration timer was not actually ever initialized since
the only place for registering the timeout was in the timeout handler.
Fix this by initializing the timer whenever a new PMKSA cache entry is
added to the beginning of the list (i.e., when it was the first entry or
expires before the entry that was previously going to expire first).

Commit 4378fc14eb started using QoS Data
frames for QoS STAs. It used the correct flags value for WPA/RSN
EAPOL-Key frames, but wrong flags for IEEE 802.1X EAPOL frames. The
WPA_STA_WMM value used in driver_nl80211.c happens to be identical to
WLAN_STA_ASSOC in sta->flags and this makes driver_nl80211.c try to use
QoS header for all STAs. Fix this by properly converting the flags from
WLAN_STA_* to WPA_STA_*. [Bug 426]

The -N and -C command line parameters can be used to add arbitrary
RADIUS attributes to the messages. However, these were truncated to
about 128 bytes when the actually message was constructed. Fix this by
using larger buffers to allow the maximum attribute length (253 octets
of payload) to be used. [Bug 458]
