419# wpa_supplicant depends on strong random number generation being available

421# data when needed, e.g., for key generation. On Linux and BSD systems, this
422# works by reading /dev/urandom. It should be noted that the OS entropy pool
423# needs to be properly initialized before wpa_supplicant is started. This is
424# important especially on embedded devices that do not have a hardware random
425# number generator and may by default start up with minimal entropy available
426# for random number generation.
427#
428# As a safety net, wpa_supplicant is by default trying to internally collect
429# additional entropy for generating random data to mix in with the data fetched
430# from the OS. This by itself is not considered to be very strong, but it may
431# help in cases where the system pool is not initialized properly. However, it
432# is very strongly recommended that the system pool is initialized with enough
433# entropy either by using hardware assisted random number generator or by
434# storing state over device reboots.
435#
436# wpa_supplicant can be configured to maintain its own entropy store over

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

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

540# Supported ACS drivers:
541# * ath9k
542# * ath5k
543# * ath10k
