+# Workaround for key reinstallation attacks
+#
+# This parameter can be used to disable retransmission of EAPOL-Key frames that
+# are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This
+# is similar to setting wpa_group_update_count=1 and

+# extended timeout on the response to avoid causing issues with stations that
+# may use aggressive power saving have very long time in replying to the
+# EAPOL-Key messages.
+#
+# This option can be used to work around key reinstallation attacks on the
+# station (supplicant) side in cases those station devices cannot be updated
+# for some reason. By removing the retransmissions the attacker cannot cause
+# key reinstallation with a delayed frame transmission. This is related to the
+# station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
+# CVE-2017-13080, and CVE-2017-13081.

+# SAE password
+# This parameter can be used to set passwords for SAE. By default, the

+# wpa_passphrase follows the WPA-PSK constraints (8..63 characters) even though
+# SAE passwords do not have such constraints. If the BSS enabled both SAE and
+# WPA-PSK and both values are set, SAE uses the sae_password values and WPA-PSK
+# uses the wpa_passphrase value.
+#
+# Each sae_password entry is added to a list of available passwords. This
+# corresponds to the dot11RSNAConfigPasswordValueEntry. sae_password value
+# starts with the password (dot11RSNAConfigPasswordCredential). That value can
+# be followed by optional peer MAC address (dot11RSNAConfigPasswordPeerMac) and
+# by optional password identifier (dot11RSNAConfigPasswordIdentifier). In
+# addition, an optional VLAN ID specification can be used to bind the station
+# to the specified VLAN whenver the specific SAE password entry is used.
+#
+# If the peer MAC address is not included or is set to the wildcard address
+# (ff:ff:ff:ff:ff:ff), the entry is available for any station to use. If a
+# specific peer MAC address is included, only a station with that MAC address
+# is allowed to use the entry.
+#
+# If the password identifier (with non-zero length) is included, the entry is
+# limited to be used only with that specified identifier.
+
+# The last matching (based on peer MAC address and identifier) entry is used to
+# select which password to use. Setting sae_password to an empty string has a
+# special meaning of removing all previously added entries.
+#
+# sae_password uses the following encoding:
+#<password/credential>[|mac=<peer mac>][|vlanid=<VLAN ID>][|id=<identifier>]

+# Per-BSS airtime weight. In multi-BSS mode, set for each BSS and hostapd will
+# configure station weights to enforce the correct ratio between BSS weights
+# depending on the number of active stations. The *ratios* between different
+# BSSes is what's important, not the absolute numbers.
+# Must be set for all BSSes if airtime_mode=2 or 3, has no effect otherwise.

+# Whether the current BSS should be limited (when airtime_mode=3).
+#
+# If set, the BSS weight ratio will be applied in the case where the current BSS
+# would exceed the share defined by the BSS weight ratio. E.g., if two BSSes are
+# set to the same weights, and one is set to limited, the limited BSS will get
+# no more than half the available airtime, but if the non-limited BSS has more
+# stations active, that *will* be allowed to exceed its half of the available
+# airtime.

##### TESTING OPTIONS #########################################################
#
# The options in this section are only available when the build configuration
# - is not the same as the MAC address of the radio
# - is not the same as any other explicitly specified BSSID
#
+# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
+# hostapd to use the driver auto-generated interface address (e.g., to use the
+# exact MAC addresses allocated to the device).
+#
# Not all drivers support multiple BSSes. The exact mechanism for determining
# the driver capabilities is driver specific. With the current (i.e., a recent
# kernel) drivers using nl80211, this information can be checked with "iw list"
