# Example hostapd build time configuration
#
# This file lists the configuration options that are used when building the
# hostapd binary. All lines starting with # are ignored. Configuration option
# lines must be commented out complete, if they are not to be included, i.e.,
# just setting VARIABLE=n is not disabling that variable.
#
# This file is included in Makefile, so variables like CFLAGS and LIBS can also
# be modified from here. In most cass, these lines should use += in order not
# to override previous values of the variables.

# hostapd depends on strong random number generation being available from the
# operating system. os_get_random() function is used to fetch random data when
# needed, e.g., for key generation. On Linux and BSD systems, this works by
# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
# properly initialized before hostapd is started. This is important especially
# on embedded devices that do not have a hardware random number generator and
# may by default start up with minimal entropy available for random number
# generation.
#
# As a safety net, hostapd is by default trying to internally collect
# additional entropy for generating random data to mix in with the data
# fetched from the OS. This by itself is not considered to be very strong, but
# it may help in cases where the system pool is not initialized properly.
# However, it is very strongly recommended that the system pool is initialized
# with enough entropy either by using hardware assisted random number
# generator or by storing state over device reboots.
#
# hostapd can be configured to maintain its own entropy store over restarts to
# enhance random number generation. This is not perfect, but it is much more
# secure than using the same sequence of random numbers after every reboot.
# This can be enabled with -e<entropy file> command line option. The specified
# file needs to be readable and writable by hostapd.
#
# If the os_get_random() is known to provide strong random data (e.g., on
# Linux/BSD, the board in question is known to have reliable source of random
# data from /dev/urandom), the internal hostapd random pool can be disabled.
# This will save some in binary size and CPU use. However, this should only be
# considered for builds that are known to be used on devices that meet the
# requirements described above.

# Testing options
# This can be used to enable some testing options (see also the example

# Automatic Channel Selection
# This will allow hostapd to pick the channel automatically when channel is set
# to "acs_survey" or "0". Eventually, other ACS algorithms can be added in
# similar way.
#
# Automatic selection is currently only done through initialization, later on
# we hope to do background checks to keep us moving to more ideal channels as
# time goes by. ACS is currently only supported through the nl80211 driver and
# your driver must have survey dump capability that is filled by the driver
# during scanning.
#
# You can customize the ACS survey algorithm with the hostapd.conf variable
# acs_num_scans.

# * ath9k
# * ath5k
# * ath10k
