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#
68fa00c3
JM
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).

1620#
1621# This parameter can be used to disable retransmission of EAPOL-Key frames that
1622# are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This
1623# is similar to setting wpa_group_update_count=1 and
1624# wpa_pairwise_update_count=1, but with no impact to message 1/4 and with
1625# extended timeout on the response to avoid causing issues with stations that
1626# may use aggressive power saving have very long time in replying to the
1627# EAPOL-Key messages.
1628#
1629# This option can be used to work around key reinstallation attacks on the
1630# station (supplicant) side in cases those station devices cannot be updated
1631# for some reason. By removing the retransmissions the attacker cannot cause
1632# key reinstallation with a delayed frame transmission. This is related to the
1633# station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
1634# CVE-2017-13080, and CVE-2017-13081.
