420# wpa_supplicant depends on strong random number generation being available
421# from the operating system. os_get_random() function is used to fetch random
422# data when needed, e.g., for key generation. On Linux and BSD systems, this
423# works by reading /dev/urandom. It should be noted that the OS entropy pool
424# needs to be properly initialized before wpa_supplicant is started. This is
425# important especially on embedded devices that do not have a hardware random
426# number generator and may by default start up with minimal entropy available
427# for random number generation.
428#
429# As a safety net, wpa_supplicant is by default trying to internally collect
430# additional entropy for generating random data to mix in with the data fetched
431# from the OS. This by itself is not considered to be very strong, but it may
432# help in cases where the system pool is not initialized properly. However, it
433# is very strongly recommended that the system pool is initialized with enough
434# entropy either by using hardware assisted random number generator or by
435# storing state over device reboots.
436#
437# wpa_supplicant can be configured to maintain its own entropy store over
438# restarts to enhance random number generation. This is not perfect, but it is
439# much more secure than using the same sequence of random numbers after every
440# reboot. This can be enabled with -e<entropy file> command line option. The
441# specified file needs to be readable and writable by wpa_supplicant.

528# TODO: Extend parser to be able to parse "channel=acs_survey" as an alternative
529# to "channel=0". This would enable us to eventually add other ACS algorithms in
530# similar way.

532# Automatic selection is currently only done through initialization, later on
533# we hope to do background checks to keep us moving to more ideal channels as
534# time goes by. ACS is currently only supported through the nl80211 driver and
535# your driver must have survey dump capability that is filled by the driver
536# during scanning.
537#
538# TODO: In analogy to hostapd be able to customize the ACS survey algorithm with
539# a newly to create wpa_supplicant.conf variable acs_num_scans.

541# Supported ACS drivers:
