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.

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