Relational operators (==) have higher precedence than the ternary
conditional in C. The last_subtype check for association/reassociation
was broken due to incorrect assumption about the precedence. Fix this by
adding parenthesis around the ternary conditional.
The previous implementation worked for Association Request frames by
accident since WLAN_FC_STYPE_ASSOC_REQ happens to have value 0 and when
the last receive frame was an Association Request frame, the
sta->last_subtype == reassoc check was true and non-zero
WLAN_FC_STYPE_REASSOC_REQ was interpreted as true. However, this was
broken for Reassociation Request frame. reassoc == 1 in that case could
have matched received Association Response frame (subtype == 1), but
those are not received in AP mode and as such, this did not break other
behavior apart from not being able to drop duplicated Reassociation
Request frames.

This adds helper functions for deriving PMK and PMKID from ERP exchange
in FILS shared key authentication as defined in IEEE Std 802.11ai-2016,
12.12.2.5.2 (PMKSA key derivation with FILS authentication). These
functions is used to fix PMK and PMKID derivation which were previously
using the rMSK directly as PMK instead of following the FILS protocol to
derive PMK with HMAC from nonces and rMSK.

Authentication and Deauthentication frames are not used in DMG/IEEE
802.11ad networks. For DMG/IEEE 802.11ad the following was implemented:
Upon receiving association request, allocate the sta object and
initialize it as if authentication took place. Upon receiving
disassociation, deallocate the sta object.
ap_sta_disassociate/ap_sta_deauthenticate/ap_sta_disconnect all use
disassociation instead of deauthentication. In driver_nl80211,
i802_sta_deauth() is routed to i802_sta_disassoc().

both in terms of TSF of the BSS that the interface that requested the
scan is connected to (if available).
Add flags to indicate whether the driver supports dwell time
configuration and scan information reporting.

It was possible to hit the previously used maximum of 100 active session
in some hwsim test case sequences like this one: eap_proto_pwd_errors
eap_proto_ikev2_errors eap_proto_sim_errors. This happened due to the
large number of RADIUS authentication iterations in short period of
time, i.e., within the 10 second timeout for expiring completed

on expiring completed sessions from 10 to 5 seconds.

(enum wpa_alg) rather than int. This ensures the return value is

It is apparently possible for the NL80211_CMD_UNEXPECTED_4ADDR_FRAME
event to be delivered to hostapd before the NL80211_CMD_FRAME_TX_STATUS
event for (Re)Association Response frame. This resulted in the 4-address
WDS mode not getting enabled for a STA. This could occur in particular
when operating under heavy load and the STA is reconnecting to the same
AP in a sequence where Deauthentication frame is followed immediately by
Authentication frame and the driver event processing gets delayed due to
removal of the previous netdev taking time in the middle of this
sequence.
Fix this by recording a pending item for 4-address WDS enabling if the
NL80211_CMD_UNEXPECTED_4ADDR_FRAME event would have been dropped due to
incompleted association and then process this pending item if the TX
status for the (Re)Association Response frame is received and it shows
that the frame was acknowledged.
