1 # Example hostapd build time configuration
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.
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.

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