1# Example hostapd build time configuration
2#
3# This file lists the configuration options that are used when building the
4# hostapd binary. All lines starting with # are ignored. Configuration option
5# lines must be commented out complete, if they are not to be included, i.e.,
6# just setting VARIABLE=n is not disabling that variable.
7#
8# This file is included in Makefile, so variables like CFLAGS and LIBS can also
9# be modified from here. In most cass, these lines should use += in order not
10# to override previous values of the variables.

224# hostapd depends on strong random number generation being available from the
225# operating system. os_get_random() function is used to fetch random data when
226# needed, e.g., for key generation. On Linux and BSD systems, this works by
227# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
228# properly initialized before hostapd is started. This is important especially
229# on embedded devices that do not have a hardware random number generator and
230# may by default start up with minimal entropy available for random number
231# generation.
232#
233# As a safety net, hostapd is by default trying to internally collect
234# additional entropy for generating random data to mix in with the data
235# fetched from the OS. This by itself is not considered to be very strong, but
236# it may help in cases where the system pool is not initialized properly.
237# However, it is very strongly recommended that the system pool is initialized
238# with enough entropy either by using hardware assisted random number
239# generator or by storing state over device reboots.
240#
241# hostapd can be configured to maintain its own entropy store over restarts to
242# enhance random number generation. This is not perfect, but it is much more
243# secure than using the same sequence of random numbers after every reboot.
244# This can be enabled with -e<entropy file> command line option. The specified
245# file needs to be readable and writable by hostapd.
246#
247# If the os_get_random() is known to provide strong random data (e.g., on
248# Linux/BSD, the board in question is known to have reliable source of random
249# data from /dev/urandom), the internal hostapd random pool can be disabled.
