173# ACS tuning - Automatic Channel Selection
174# See: https://wireless.wiki.kernel.org/en/users/documentation/acs
175#
176# You can customize the ACS survey algorithm with following variables:
177#
178# acs_num_scans requirement is 1..100 - number of scans to be performed that
179# are used to trigger survey data gathering of an underlying device driver.
180# Scans are passive and typically take a little over 100ms (depending on the
181# driver) on each available channel for given hw_mode. Increasing this value
182# means sacrificing startup time and gathering more data wrt channel
183# interference that may help choosing a better channel. This can also help fine
184# tune the ACS scan time in case a driver has different scan dwell times.
185#
186# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
187# used to increase (or decrease) the likelihood of a specific channel to be
188# selected by the ACS algorithm. The total interference factor for each channel
189# gets multiplied by the specified bias value before finding the channel with
190# the lowest value. In other words, values between 0.0 and 1.0 can be used to
191# make a channel more likely to be picked while values larger than 1.0 make the
192# specified channel less likely to be picked. This can be used, e.g., to prefer
193# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
194# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

1176# For example, check_cert_subject=C=US/O=XX/OU=ABC/OU=XYZ/CN=1234 will check

1178# comes first in terms of the order in the client certificate (DN field of

1181# check_cert_subject.
1182#
1183# This option also allows '*' as a wildcard. This option has some limitation.

1185#
1186# For example, check_cert_subject=C=US/O=XX/OU=Production* and we have two

1188# (C=US/O=XX/OU=Production Unit) and DN of the subject in the second client is
1189# (C=US/O=XX/OU=Production Factory). In this case, hostapd will allow both

1768# Workaround for key reinstallation attacks
1769#
1770# This parameter can be used to disable retransmission of EAPOL-Key frames that
1771# are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This
1772# is similar to setting wpa_group_update_count=1 and
1773# wpa_pairwise_update_count=1, but with no impact to message 1/4 and with
1774# extended timeout on the response to avoid causing issues with stations that
1775# may use aggressive power saving have very long time in replying to the
1776# EAPOL-Key messages.
1777#
1778# This option can be used to work around key reinstallation attacks on the
1779# station (supplicant) side in cases those station devices cannot be updated
1780# for some reason. By removing the retransmissions the attacker cannot cause
1781# key reinstallation with a delayed frame transmission. This is related to the
1782# station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
1783# CVE-2017-13080, and CVE-2017-13081.
1784#
1785# This workaround might cause interoperability issues and reduced robustness of

1890# WPA-PSK and both values are set, SAE uses the sae_password values and WPA-PSK
1891# uses the wpa_passphrase value.
1892#
1893# Each sae_password entry is added to a list of available passwords. This
1894# corresponds to the dot11RSNAConfigPasswordValueEntry. sae_password value
1895# starts with the password (dot11RSNAConfigPasswordCredential). That value can
1896# be followed by optional peer MAC address (dot11RSNAConfigPasswordPeerMac) and
1897# by optional password identifier (dot11RSNAConfigPasswordIdentifier). In
1898# addition, an optional VLAN ID specification can be used to bind the station
1899# to the specified VLAN whenever the specific SAE password entry is used.
1900#
1901# If the peer MAC address is not included or is set to the wildcard address
1902# (ff:ff:ff:ff:ff:ff), the entry is available for any station to use. If a
1903# specific peer MAC address is included, only a station with that MAC address
1904# is allowed to use the entry.

2329# the PushButton config method is left in M1 (if included in config_methods

3010##### Multiple BSSID support ##################################################
3011#
3012# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
3013# interfaces). Other BSSIDs can be added by using separator 'bss' with
3014# default interface name to be allocated for the data packets of the new BSS.
3015#
3016# hostapd will generate BSSID mask based on the BSSIDs that are
3017# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
3018# not the case, the MAC address of the radio must be changed before starting
3019# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
3020# every secondary BSS, this limitation is not applied at hostapd and other
3021# masks may be used if the driver supports them (e.g., swap the locally
3022# administered bit)
3023#
3024# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
3025# specified using the 'bssid' parameter.
3026# If an explicit BSSID is specified, it must be chosen such that it:
3027# - results in a valid MASK that covers it and the dev_addr
3028# - is not the same as the MAC address of the radio
3029# - is not the same as any other explicitly specified BSSID
3030#
3031# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
3032# hostapd to use the driver auto-generated interface address (e.g., to use the
3033# exact MAC addresses allocated to the device).
3034#
3035# Not all drivers support multiple BSSes. The exact mechanism for determining
3036# the driver capabilities is driver specific. With the current (i.e., a recent
3037# kernel) drivers using nl80211, this information can be checked with "iw list"
3038# (search for "valid interface combinations").
3039#
3040# Please note that hostapd uses some of the values configured for the first BSS
3041# as the defaults for the following BSSes. However, it is recommended that all
3042# BSSes include explicit configuration of all relevant configuration items.
