距离上一篇文章的更新已经将近半年了，这半年忙项目忙得几乎没有什么时间给自己积累一些东西，也没什么心思转到这边来写点东西，当一个项目放到自己身上的时候，发现并不像开发一个模块或一个功能那么简单，涉及方方面面，各种琐碎的的事情会占据大量的时间。
前面写的关于hostapd的文章都太浅显了，一般都没怎么涉及到具体的功能，只是简单的分析了一下代码的流程，然而对于实际的功能开发和bug调试其实用处不大，后面的文章将从wpa_supplicant入手做进一步的了解。hostapd主要用于AP端的开发，比如路由器，无线AP等，但是wpa_supplicant的使用会更广泛，只要是无线客户端，需要和AP建立链接就可能会用到wpa_supplicant（除了一些厂商将加密和WPS整合到driver外，如MTK等），而且它支持的协议多。
下面是最新的hostapd.git里面share出来的一份wpa_supplicant.conf配置文件，一般成熟的公司可能不会很喜欢新的code，会更喜欢稳定的code，但是对于自己学习还是会比较追新，所以关于hostapd的代码可以经常到git://w1.fi/hostap.git pull 一下，看看都加了些什么。
[you@you hostapd.git]$ find -name wpa_supplicant.conf
./wpa_supplicant/wpa_supplicant.conf
[you@you hostapd.git]$ cat ./wpa_supplicant/wpa_supplicant.conf
##### Example wpa_supplicant configuration file ###############################
#
# This file describes configuration file format and lists all available option.
# Please also take a look at simpler configuration examples in ‘examples‘
# subdirectory.
#
# Empty lines and lines starting with # are ignored
# NOTE! This file may contain password information and should probably be made
# readable only by root user on multiuser systems.
# Note: All file paths in this configuration file should use full (absolute,
# not relative to working directory) path in order to allow working directory
# to be changed. This can happen if wpa_supplicant is run in the background.
# Whether to allow wpa_supplicant to update (overwrite) configuration
#
# This option can be used to allow wpa_supplicant to overwrite configuration
# file whenever configuration is changed (e.g., new network block is added with
# wpa_cli or wpa_gui, or a password is changed). This is required for
# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
# Please note that overwriting configuration file will remove the comments from
# it.
#update_config=1
# global configuration (shared by all network blocks)
#
# Parameters for the control interface. If this is specified, wpa_supplicant
# will open a control interface that is available for external programs to
# manage wpa_supplicant. The meaning of this string depends on which control
# interface mechanism is used. For all cases, the existence of this parameter
# in configuration is used to determine whether the control interface is
# enabled.
#
# For UNIX domain sockets (default on Linux and BSD): This is a directory that
# will be created for UNIX domain sockets for listening to requests from
# external programs (CLI/GUI, etc.) for status information and configuration.
# The socket file will be named based on the interface name, so multiple
# wpa_supplicant processes can be run at the same time if more than one
# interface is used.
# /var/run/wpa_supplicant is the recommended directory for sockets and by
# default, wpa_cli will use it when trying to connect with wpa_supplicant.
#
# Access control for the control interface can be configured by setting the
# directory to allow only members of a group to use sockets. This way, it is
# possible to run wpa_supplicant as root (since it needs to change network
# configuration and open raw sockets) and still allow GUI/CLI components to be
# run as non-root users. However, since the control interface can be used to
# change the network configuration, this access needs to be protected in many
# cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
# want to allow non-root users to use the control interface, add a new group
# and change this value to match with that group. Add users that should have
# control interface access to this group. If this variable is commented out or
# not included in the configuration file, group will not be changed from the
# value it got by default when the directory or socket was created.
#
# When configuring both the directory and group, use following format:
# DIR=/var/run/wpa_supplicant GROUP=wheel
# DIR=/var/run/wpa_supplicant GROUP=0
# (group can be either group name or gid)
#
# For UDP connections (default on Windows): The value will be ignored. This
# variable is just used to select that the control interface is to be created.
# The value can be set to, e.g., udp (ctrl_interface=udp)
#
# For Windows Named Pipe: This value can be used to set the security descriptor
# for controlling access to the control interface. Security descriptor can be
# set using Security Descriptor String Format (see http://msdn.microsoft.com/
# library/default.asp?url=/library/en-us/secauthz/security/
# security_descriptor_string_format.asp). The descriptor string needs to be
# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty
# DACL (which will reject all connections). See README-Windows.txt for more
# information about SDDL string format.
#
ctrl_interface=/var/run/wpa_supplicant
# IEEE 802.1X/EAPOL version
# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
# EAPOL version 2. However, there are many APs that do not handle the new
# version number correctly (they seem to drop the frames completely). In order
# to make wpa_supplicant interoperate with these APs, the version number is set
# to 1 by default. This configuration value can be used to set it to the new
# version (2).
# Note: When using MACsec, eapol_version shall be set to 3, which is
# defined in IEEE Std 802.1X-2010.
eapol_version=1
# AP scanning/selection
# By default, wpa_supplicant requests driver to perform AP scanning and then
# uses the scan results to select a suitable AP. Another alternative is to
# allow the driver to take care of AP scanning and selection and use
# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
# information from the driver.
# 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
# the currently enabled networks are found, a new network (IBSS or AP mode
# operation) may be initialized (if configured) (default)
# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
# parameters (e.g., WPA IE generation); this mode can also be used with
# non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
# APs (i.e., external program needs to control association). This mode must
# also be used when using wired Ethernet drivers.
# Note: macsec_qca driver is one type of Ethernet driver which implements
# macsec feature.
# 2: like 0, but associate with APs using security policy and SSID (but not
# BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
# enable operation with hidden SSIDs and optimized roaming; in this mode,
# the network blocks in the configuration file are tried one by one until
# the driver reports successful association; each network block should have
# explicit security policy (i.e., only one option in the lists) for
# key_mgmt, pairwise, group, proto variables
# Note: ap_scan=2 should not be used with the nl80211 driver interface (the
# current Linux interface). ap_scan=1 is optimized work working with nl80211.
# For finding networks using hidden SSID, scan_ssid=1 in the network block can
# be used with nl80211.
# When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
# created immediately regardless of scan results. ap_scan=1 mode will first try
# to scan for existing networks and only if no matches with the enabled
# networks are found, a new IBSS or AP mode network is created.
ap_scan=1
# Whether to force passive scan for network connection
#
# By default, scans will send out Probe Request frames on channels that allow
# active scanning. This advertise the local station to the world. Normally this
# is fine, but users may wish to do passive scanning where the radio should only
# listen quietly for Beacon frames and not send any Probe Request frames. Actual
# functionality may be driver dependent.
#
# This parameter can be used to force only passive scanning to be used
# for network connection cases. It should be noted that this will slow
# down scan operations and reduce likelihood of finding the AP. In
# addition, some use cases will override this due to functional
# requirements, e.g., for finding an AP that uses hidden SSID
# (scan_ssid=1) or P2P device discovery.
#
# 0: Do normal scans (allow active scans) (default)
# 1: Do passive scans.
#passive_scan=0
# MPM residency
# By default, wpa_supplicant implements the mesh peering manager (MPM) for an
# open mesh. However, if the driver can implement the MPM, you may set this to
# 0 to use the driver version. When AMPE is enabled, the wpa_supplicant MPM is
# always used.
# 0: MPM lives in the driver
# 1: wpa_supplicant provides an MPM which handles peering (default)
#user_mpm=1
# Maximum number of peer links (0-255; default: 99)
# Maximum number of mesh peering currently maintained by the STA.
#max_peer_links=99
# Timeout in seconds to detect STA inactivity (default: 300 seconds)
#
# This timeout value is used in mesh STA to clean up inactive stations.
#mesh_max_inactivity=300
# cert_in_cb - Whether to include a peer certificate dump in events
# This controls whether peer certificates for authentication server and
# its certificate chain are included in EAP peer certificate events. This is
# enabled by default.
#cert_in_cb=1
# EAP fast re-authentication
# By default, fast re-authentication is enabled for all EAP methods that
# support it. This variable can be used to disable fast re-authentication.
# Normally, there is no need to disable this.
fast_reauth=1
# OpenSSL Engine support
# These options can be used to load OpenSSL engines.

# on cipher suite configuration. This is applicable only if wpa_supplicant is
# built to use OpenSSL.
#openssl_ciphers=DEFAULT:!EXP:!LOW
# Dynamic EAP methods

#wps_priority=0
# Maximum number of BSS entries to keep in memory
# Default: 200
# This can be used to limit memory use on the BSS entries (cached scan
# results). A larger value may be needed in environments that have huge number
# of APs when using ap_scan=1 mode.
#bss_max_count=200
# Automatic scan
# This is an optional set of parameters for automatic scanning
# within an interface in following format:
#autoscan=<autoscan module name>:<module parameters>
# autoscan is like bgscan but on disconnected or inactive state.
# For instance, on exponential module parameters would be <base>:<limit>
#autoscan=exponential:3:300
# Which means a delay between scans on a base exponential of 3,
# up to the limit of 300 seconds (3, 9, 27 ... 300)
# For periodic module, parameters would be <fixed interval>
#autoscan=periodic:30
# So a delay of 30 seconds will be applied between each scan.
# Note: If sched_scan_plans are configured and supported by the driver,
# autoscan is ignored.
# filter_ssids - SSID-based scan result filtering
# 0 = do not filter scan results (default)
# 1 = only include configured SSIDs in scan results/BSS table
#filter_ssids=0
# Password (and passphrase, etc.) backend for external storage
# format: <backend name>[:<optional backend parameters>]
#ext_password_backend=test:pw1=password|pw2=testing

#p2p_go_max_inactivity=300
# Passphrase length (8..63) for P2P GO
#
# This parameter controls the length of the random passphrase that is
# generated at the GO. Default: 8.
#p2p_passphrase_len=8
# Extra delay between concurrent P2P search iterations
#
# This value adds extra delay in milliseconds between concurrent search
# iterations to make p2p_find friendlier to concurrent operations by avoiding
# it from taking 100% of radio resources. The default value is 500 ms.
#p2p_search_delay=500
# Opportunistic Key Caching (also known as Proactive Key Caching) default
# This parameter can be used to set the default behavior for the
# proactive_key_caching parameter. By default, OKC is disabled unless enabled
# with the global okc=1 parameter or with the per-network
# proactive_key_caching=1 parameter. With okc=1, OKC is enabled by default, but
# can be disabled with per-network proactive_key_caching=0 parameter.
#okc=0
# Protected Management Frames default
# This parameter can be used to set the default behavior for the ieee80211w
# parameter for RSN networks. By default, PMF is disabled unless enabled with
# the global pmf=1/2 parameter or with the per-network ieee80211w=1/2 parameter.
# With pmf=1/2, PMF is enabled/required by default, but can be disabled with the
# per-network ieee80211w parameter. This global default value does not apply
# for non-RSN networks (key_mgmt=NONE) since PMF is available only when using
# RSN.
#pmf=0
# Enabled SAE finite cyclic groups in preference order
# By default (if this parameter is not set), the mandatory group 19 (ECC group
# defined over a 256-bit prime order field) is preferred, but other groups are
# also enabled. If this parameter is set, the groups will be tried in the
# indicated order. The group values are listed in the IANA registry:
# http://www.iana.org/assignments/ipsec-registry/ipsec-registry.xml#ipsec-registry-9
#sae_groups=21 20 19 26 25
# Default value for DTIM period (if not overridden in network block)
#dtim_period=2
# Default value for Beacon interval (if not overridden in network block)
#beacon_int=100
# Additional vendor specific elements for Beacon and Probe Response frames
# This parameter can be used to add additional vendor specific element(s) into
# the end of the Beacon and Probe Response frames. The format for these
# element(s) is a hexdump of the raw information elements (id+len+payload for
# one or more elements). This is used in AP and P2P GO modes.
#ap_vendor_elements=dd0411223301
# Ignore scan results older than request
#
# The driver may have a cache of scan results that makes it return
# information that is older than our scan trigger. This parameter can
# be used to configure such old information to be ignored instead of
# allowing it to update the internal BSS table.
#ignore_old_scan_res=0
# scan_cur_freq: Whether to scan only the current frequency
# 0: Scan all available frequencies. (Default)
# 1: Scan current operating frequency if another VIF on the same radio
# is already associated.
# MAC address policy default
# 0 = use permanent MAC address
# 1 = use random MAC address for each ESS connection
# 2 = like 1, but maintain OUI (with local admin bit set)
#
# By default, permanent MAC address is used unless policy is changed by
# the per-network mac_addr parameter. Global mac_addr=1 can be used to
# change this default behavior.
#mac_addr=0
# Lifetime of random MAC address in seconds (default: 60)
#rand_addr_lifetime=60
# MAC address policy for pre-association operations (scanning, ANQP)
# 0 = use permanent MAC address

# Interworking (IEEE 802.11u)
# Enable Interworking
# interworking=1
# Homogenous ESS identifier
# If this is set, scans will be used to request response only from BSSes
# belonging to the specified Homogeneous ESS. This is used only if interworking
# is enabled.
# hessid=00:11:22:33:44:55
# Automatic network selection behavior
# 0 = do not automatically go through Interworking network selection
# (i.e., require explicit interworking_select command for this; default)
# 1 = perform Interworking network selection if one or more
# credentials have been configured and scan did not find a
# matching network block
#auto_interworking=0
# credential block
#
# Each credential used for automatic network selection is configured as a set
# of parameters that are compared to the information advertised by the APs when
# interworking_select and interworking_connect commands are used.
#
# credential fields:
#
# temporary: Whether this credential is temporary and not to be saved
#
# priority: Priority group
# By default, all networks and credentials get the same priority group
# (0). This field can be used to give higher priority for credentials
# (and similarly in struct wpa_ssid for network blocks) to change the
# Interworking automatic networking selection behavior. The matching
# network (based on either an enabled network block or a credential)
# with the highest priority value will be selected.
#
# pcsc: Use PC/SC and SIM/USIM card
#
# realm: Home Realm for Interworking
#
# username: Username for Interworking network selection
#
# password: Password for Interworking network selection
#
# ca_cert: CA certificate for Interworking network selection
#
# client_cert: File path to client certificate file (PEM/DER)
# This field is used with Interworking networking selection for a case
# where client certificate/private key is used for authentication
# (EAP-TLS). Full path to the file should be used since working
# directory may change when wpa_supplicant is run in the background.
#
# Alternatively, a named configuration blob can be used by setting
# this to blob://blob_name.
#
# private_key: File path to client private key file (PEM/DER/PFX)
# When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
# commented out. Both the private key and certificate will be read
# from the PKCS#12 file in this case. Full path to the file should be
# used since working directory may change when wpa_supplicant is run
# in the background.
#
# Windows certificate store can be used by leaving client_cert out and
# configuring private_key in one of the following formats:
#
# cert://substring_to_match
#
# hash://certificate_thumbprint_in_hex
#
# For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
#
# Note that when running wpa_supplicant as an application, the user
# certificate store (My user account) is used, whereas computer store
# (Computer account) is used when running wpasvc as a service.
#
# Alternatively, a named configuration blob can be used by setting
# this to blob://blob_name.
#
# private_key_passwd: Password for private key file
#
# imsi: IMSI in <MCC> | <MNC> | ‘-‘ | <MSIN> format
#
# milenage: Milenage parameters for SIM/USIM simulator in <Ki>:<OPc>:<SQN>
# format
#
# domain: Home service provider FQDN(s)
# This is used to compare against the Domain Name List to figure out
# whether the AP is operated by the Home SP. Multiple domain entries can
# be used to configure alternative FQDNs that will be considered home
# networks.
#
# roaming_consortium: Roaming Consortium OI
# If roaming_consortium_len is non-zero, this field contains the
# Roaming Consortium OI that can be used to determine which access
# points support authentication with this credential. This is an
# alternative to the use of the realm parameter. When using Roaming
# Consortium to match the network, the EAP parameters need to be
# pre-configured with the credential since the NAI Realm information
# may not be available or fetched.
#
# eap: Pre-configured EAP method
# This optional field can be used to specify which EAP method will be
# used with this credential. If not set, the EAP method is selected
# automatically based on ANQP information (e.g., NAI Realm).
#
# phase1: Pre-configure Phase 1 (outer authentication) parameters
# This optional field is used with like the ‘eap‘ parameter.
#
# phase2: Pre-configure Phase 2 (inner authentication) parameters
# This optional field is used with like the ‘eap‘ parameter.
#
# excluded_ssid: Excluded SSID
# This optional field can be used to excluded specific SSID(s) from
# matching with the network. Multiple entries can be used to specify more
# than one SSID.
#
# roaming_partner: Roaming partner information
# This optional field can be used to configure preferences between roaming
# partners. The field is a string in following format:
# <FQDN>,<0/1 exact match>,<priority>,<* or country code>
# (non-exact match means any subdomain matches the entry; priority is in
# 0..255 range with 0 being the highest priority)
#
# update_identifier: PPS MO ID
# (Hotspot 2.0 PerProviderSubscription/UpdateIdentifier)
#
# provisioning_sp: FQDN of the SP that provisioned the credential
# This optional field can be used to keep track of the SP that provisioned
# the credential to find the PPS MO (./Wi-Fi/<provisioning_sp>).
#
# Minimum backhaul threshold (PPS/<X+>/Policy/MinBackhauldThreshold/*)
# These fields can be used to specify minimum download/upload backhaul
# bandwidth that is preferred for the credential. This constraint is
# ignored if the AP does not advertise WAN Metrics information or if the
# limit would prevent any connection. Values are in kilobits per second.
# min_dl_bandwidth_home
# min_ul_bandwidth_home
# min_dl_bandwidth_roaming
# min_ul_bandwidth_roaming
#
# max_bss_load: Maximum BSS Load Channel Utilization (1..255)
# (PPS/<X+>/Policy/MaximumBSSLoadValue)
# This value is used as the maximum channel utilization for network
# selection purposes for home networks. If the AP does not advertise
# BSS Load or if the limit would prevent any connection, this constraint
# will be ignored.
#
# req_conn_capab: Required connection capability
# (PPS/<X+>/Policy/RequiredProtoPortTuple)
# This value is used to configure set of required protocol/port pairs that
# a roaming network shall support (include explicitly in Connection
# Capability ANQP element). This constraint is ignored if the AP does not
# advertise Connection Capability or if this constraint would prevent any
# network connection. This policy is not used in home networks.
# Format: <protocol>[:<comma-separated list of ports]
# Multiple entries can be used to list multiple requirements.
# For example, number of common TCP protocols:
# req_conn_capab=6,22,80,443
# For example, IPSec/IKE:
# req_conn_capab=17:500
# req_conn_capab=50
#
# ocsp: Whether to use/require OCSP to check server certificate
# 0 = do not use OCSP stapling (TLS certificate status extension)
# 1 = try to use OCSP stapling, but not require response
# 2 = require valid OCSP stapling response
# 3 = require valid OCSP stapling response for all not-trusted
# certificates in the server certificate chain
#
# sim_num: Identifier for which SIM to use in multi-SIM devices
#
# for example:

# Scheduled scan plans
#
# A space delimited list of scan plans. Each scan plan specifies the scan
# interval and number of iterations, delimited by a colon. The last scan plan
# will run infinitely and thus must specify only the interval and not the number
# of iterations.
#
# The driver advertises the maximum number of scan plans supported. If more scan
# plans than supported are configured, only the first ones are set (up to the
# maximum supported). The last scan plan that specifies only the interval is
# always set as the last plan.
#
# If the scan interval or the number of iterations for a scan plan exceeds the
# maximum supported, it will be set to the maximum supported value.
#
# Format:
# sched_scan_plans=<interval:iterations> <interval:iterations> ... <interval>
#
# Example:
# sched_scan_plans=10:100 20:200 30
# Multi Band Operation (MBO) non-preferred channels
# A space delimited list of non-preferred channels where each channel is a colon
# delimited list of values. Reason detail is optional.
# Format:
# non_pref_chan=<oper_class>:<chan>:<preference>:<reason>[:reason_detail]
# Example:
# non_pref_chan="81:5:10:2:0 81:1:0:2:0 81:9:0:2"
# MBO Cellular Data Capabilities
# 1 = Cellular data connection available
# 2 = Cellular data connection not available
# 3 = Not cellular capable (default)
#mbo_cell_capa=3
# network block
#
# Each network (usually AP‘s sharing the same SSID) is configured as a separate
# block in this configuration file. The network blocks are in preference order
# (the first match is used).
#
# network block fields:
#
# disabled:
# 0 = this network can be used (default)
# 1 = this network block is disabled (can be enabled through ctrl_iface,
# e.g., with wpa_cli or wpa_gui)
#
# id_str: Network identifier string for external scripts. This value is passed
# to external action script through wpa_cli as WPA_ID_STR environment
# variable to make it easier to do network specific configuration.
#
# ssid: SSID (mandatory); network name in one of the optional formats:
# - an ASCII string with double quotation
# - a hex string (two characters per octet of SSID)
# - a printf-escaped ASCII string P"<escaped string>"
#
# scan_ssid:
# 0 = do not scan this SSID with specific Probe Request frames (default)
# 1 = scan with SSID-specific Probe Request frames (this can be used to
# find APs that do not accept broadcast SSID or use multiple SSIDs;
# this will add latency to scanning, so enable this only when needed)
#
# bssid: BSSID (optional); if set, this network block is used only when
# associating with the AP using the configured BSSID
#
# priority: priority group (integer)
# By default, all networks will get same priority group (0). If some of the
# networks are more desirable, this field can be used to change the order in
# which wpa_supplicant goes through the networks when selecting a BSS. The
# priority groups will be iterated in decreasing priority (i.e., the larger the
# priority value, the sooner the network is matched against the scan results).
# Within each priority group, networks will be selected based on security
# policy, signal strength, etc.
# Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not
# using this priority to select the order for scanning. Instead, they try the
# networks in the order that used in the configuration file.
#
# mode: IEEE 802.11 operation mode
# 0 = infrastructure (Managed) mode, i.e., associate with an AP (default)
# 1 = IBSS (ad-hoc, peer-to-peer)
# 2 = AP (access point)
# Note: IBSS can only be used with key_mgmt NONE (plaintext and static WEP) and
# WPA-PSK (with proto=RSN). In addition, key_mgmt=WPA-NONE (fixed group key
# TKIP/CCMP) is available for backwards compatibility, but its use is
# deprecated. WPA-None requires following network block options:
# proto=WPA, key_mgmt=WPA-NONE, pairwise=NONE, group=TKIP (or CCMP, but not
# both), and psk must also be set.
#
# frequency: Channel frequency in megahertz (MHz) for IBSS, e.g.,
# 2412 = IEEE 802.11b/g channel 1. This value is used to configure the initial
# channel for IBSS (adhoc) networks. It is ignored in the infrastructure mode.
# In addition, this value is only used by the station that creates the IBSS. If
# an IBSS network with the configured SSID is already present, the frequency of
# the network will be used instead of this configured value.
#
# pbss: Whether to use PBSS. Relevant to IEEE 802.11ad networks only.
# 0 = do not use PBSS
# 1 = use PBSS
# 2 = don‘t care (not allowed in AP mode)
# Used together with mode configuration. When mode is AP, it means to start a
# PCP instead of a regular AP. When mode is infrastructure it means connect
# to a PCP instead of AP. In this mode you can also specify 2 (don‘t care)
# which means connect to either PCP or AP.
# P2P_GO and P2P_GROUP_FORMATION modes must use PBSS in IEEE 802.11ad network.
# For more details, see IEEE Std 802.11ad-2012.
#
# scan_freq: List of frequencies to scan
# Space-separated list of frequencies in MHz to scan when searching for this
# BSS. If the subset of channels used by the network is known, this option can
# be used to optimize scanning to not occur on channels that the network does
# not use. Example: scan_freq=2412 2437 2462
#
# freq_list: Array of allowed frequencies
# Space-separated list of frequencies in MHz to allow for selecting the BSS. If
# set, scan results that do not match any of the specified frequencies are not
# considered when selecting a BSS.
#
# This can also be set on the outside of the network block. In this case,
# it limits the frequencies that will be scanned.
#
# bgscan: Background scanning
# wpa_supplicant behavior for background scanning can be specified by
# configuring a bgscan module. These modules are responsible for requesting
# background scans for the purpose of roaming within an ESS (i.e., within a
# single network block with all the APs using the same SSID). The bgscan
# parameter uses following format: "<bgscan module name>:<module parameters>"
# Following bgscan modules are available:
# simple - Periodic background scans based on signal strength
# bgscan="simple:<short bgscan interval in seconds>:<signal strength threshold>:
# <long interval>"
# bgscan="simple:30:-45:300"
# learn - Learn channels used by the network and try to avoid bgscans on other
# channels (experimental)
# bgscan="learn:<short bgscan interval in seconds>:<signal strength threshold>:
# <long interval>[:<database file name>]"
# bgscan="learn:30:-45:300:/etc/wpa_supplicant/network1.bgscan"
# Explicitly disable bgscan by setting
# bgscan=""
#
# This option can also be set outside of all network blocks for the bgscan
# parameter to apply for all the networks that have no specific bgscan
# parameter.
#

# WPA-EAP-SUITE-B-192 = Suite B 192-bit level
# OSEN = Hotspot 2.0 Rel 2 online signup connection
# If not set, this defaults to: WPA-PSK WPA-EAP
#
# ieee80211w: whether management frame protection is enabled
# 0 = disabled (default unless changed with the global pmf parameter)
# 1 = optional
# 2 = required
# The most common configuration options for this based on the PMF (protected
# management frames) certification program are:
# PMF enabled: ieee80211w=1 and key_mgmt=WPA-EAP WPA-EAP-SHA256
# PMF required: ieee80211w=2 and key_mgmt=WPA-EAP-SHA256
# (and similarly for WPA-PSK and WPA-WPSK-SHA256 if WPA2-Personal is used)

# OPEN = Open System authentication (required for WPA/WPA2)
# SHARED = Shared Key authentication (requires static WEP keys)
# LEAP = LEAP/Network EAP (only used with LEAP)

# WEP40 = WEP (Wired Equivalent Privacy) with 40-bit key [IEEE 802.11]
# If not set, this defaults to: CCMP TKIP WEP104 WEP40
#
# psk: WPA preshared key; 256-bit pre-shared key
# The key used in WPA-PSK mode can be entered either as 64 hex-digits, i.e.,
# 32 bytes or as an ASCII passphrase (in which case, the real PSK will be
# generated using the passphrase and SSID). ASCII passphrase must be between
# 8 and 63 characters (inclusive). ext:<name of external PSK field> format can
# be used to indicate that the PSK/passphrase is stored in external storage.
# This field is not needed, if WPA-EAP is used.
# Note: Separate tool, wpa_passphrase, can be used to generate 256-bit keys
# from ASCII passphrase. This process uses lot of CPU and wpa_supplicant
# startup and reconfiguration time can be optimized by generating the PSK only
# only when the passphrase or SSID has actually changed.
#
# mem_only_psk: Whether to keep PSK/passphrase only in memory
# 0 = allow psk/passphrase to be stored to the configuration file
# 1 = do not store psk/passphrase to the configuration file
#mem_only_psk=0
#
# eapol_flags: IEEE 802.1X/EAPOL options (bit field)
# Dynamic WEP key required for non-WPA mode
# bit0 (1): require dynamically generated unicast WEP key
# bit1 (2): require dynamically generated broadcast WEP key
# (3 = require both keys; default)
# Note: When using wired authentication (including macsec_qca driver),
# eapol_flags must be set to 0 for the authentication to be completed
# successfully.
#
# macsec_policy: IEEE 802.1X/MACsec options
# This determines how sessions are secured with MACsec. It is currently
# applicable only when using the macsec_qca driver interface.
# 0: MACsec not in use (default)
# 1: MACsec enabled - Should secure, accept key server‘s advice to
# determine whether to use a secure session or not.
#
# mixed_cell: This option can be used to configure whether so called mixed
# cells, i.e., networks that use both plaintext and encryption in the same
# SSID, are allowed when selecting a BSS from scan results.
# 0 = disabled (default)
# 1 = enabled
#
# proactive_key_caching:
# Enable/disable opportunistic PMKSA caching for WPA2.
# 0 = disabled (default unless changed with the global okc parameter)
# 1 = enabled
#
# wep_key0..3: Static WEP key (ASCII in double quotation, e.g. "abcde" or
# hex without quotation, e.g., 0102030405)
# wep_tx_keyidx: Default WEP key index (TX) (0..3)
#
# peerkey: Whether PeerKey negotiation for direct links (IEEE 802.11e DLS) is
# allowed. This is only used with RSN/WPA2.
# 0 = disabled (default)
# 1 = enabled
#peerkey=1
#
# wpa_ptk_rekey: Maximum lifetime for PTK in seconds. This can be used to
# enforce rekeying of PTK to mitigate some attacks against TKIP deficiencies.
#
# Following fields are only used with internal EAP implementation.
# eap: space-separated list of accepted EAP methods
# MD5 = EAP-MD5 (unsecure and does not generate keying material ->
# cannot be used with WPA; to be used as a Phase 2 method
# with EAP-PEAP or EAP-TTLS)
# MSCHAPV2 = EAP-MSCHAPv2 (cannot be used separately with WPA; to be used
# as a Phase 2 method with EAP-PEAP or EAP-TTLS)
# OTP = EAP-OTP (cannot be used separately with WPA; to be used
# as a Phase 2 method with EAP-PEAP or EAP-TTLS)
# GTC = EAP-GTC (cannot be used separately with WPA; to be used
# as a Phase 2 method with EAP-PEAP or EAP-TTLS)
# TLS = EAP-TLS (client and server certificate)
# PEAP = EAP-PEAP (with tunnelled EAP authentication)
# TTLS = EAP-TTLS (with tunnelled EAP or PAP/CHAP/MSCHAP/MSCHAPV2
# authentication)
# If not set, all compiled in methods are allowed.
#
# identity: Identity string for EAP
# This field is also used to configure user NAI for
# EAP-PSK/PAX/SAKE/GPSK.
# anonymous_identity: Anonymous identity string for EAP (to be used as the
# unencrypted identity with EAP types that support different tunnelled
# identity, e.g., EAP-TTLS). This field can also be used with
# EAP-SIM/AKA/AKA‘ to store the pseudonym identity.
# password: Password string for EAP. This field can include either the
# plaintext password (using ASCII or hex string) or a NtPasswordHash
# (16-byte MD4 hash of password) in hash:<32 hex digits> format.
# NtPasswordHash can only be used when the password is for MSCHAPv2 or
# MSCHAP (EAP-MSCHAPv2, EAP-TTLS/MSCHAPv2, EAP-TTLS/MSCHAP, LEAP).
# EAP-PSK (128-bit PSK), EAP-PAX (128-bit PSK), and EAP-SAKE (256-bit
# PSK) is also configured using this field. For EAP-GPSK, this is a
# variable length PSK. ext:<name of external password field> format can
# be used to indicate that the password is stored in external storage.
# ca_cert: File path to CA certificate file (PEM/DER). This file can have one
# or more trusted CA certificates. If ca_cert and ca_path are not
# included, server certificate will not be verified. This is insecure and
# a trusted CA certificate should always be configured when using
# EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
# change when wpa_supplicant is run in the background.
#
# Alternatively, this can be used to only perform matching of the server
# certificate (SHA-256 hash of the DER encoded X.509 certificate). In
# this case, the possible CA certificates in the server certificate chain
# are ignored and only the server certificate is verified. This is
# configured with the following format:
# hash:://server/sha256/cert_hash_in_hex
# For example: "hash://server/sha256/
# 5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
#
# On Windows, trusted CA certificates can be loaded from the system
# certificate store by setting this to cert_store://<name>, e.g.,
# ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
# Note that when running wpa_supplicant as an application, the user
# certificate store (My user account) is used, whereas computer store
# (Computer account) is used when running wpasvc as a service.
# ca_path: Directory path for CA certificate files (PEM). This path may
# contain multiple CA certificates in OpenSSL format. Common use for this
# is to point to system trusted CA list which is often installed into
# directory like /etc/ssl/certs. If configured, these certificates are
# added to the list of trusted CAs. ca_cert may also be included in that
# case, but it is not required.
# client_cert: File path to client certificate file (PEM/DER)
# Full path should be used since working directory may change when
# wpa_supplicant is run in the background.
# Alternatively, a named configuration blob can be used by setting this
# to blob://<blob name>.
# private_key: File path to client private key file (PEM/DER/PFX)
# When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
# commented out. Both the private key and certificate will be read from
# the PKCS#12 file in this case. Full path should be used since working
# directory may change when wpa_supplicant is run in the background.
# Windows certificate store can be used by leaving client_cert out and
# configuring private_key in one of the following formats:
# cert://substring_to_match
# hash://certificate_thumbprint_in_hex
# for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
# Note that when running wpa_supplicant as an application, the user
# certificate store (My user account) is used, whereas computer store
# (Computer account) is used when running wpasvc as a service.
# Alternatively, a named configuration blob can be used by setting this
# to blob://<blob name>.
# private_key_passwd: Password for private key file (if left out, this will be
# asked through control interface)
# dh_file: File path to DH/DSA parameters file (in PEM format)
# This is an optional configuration file for setting parameters for an
# ephemeral DH key exchange. In most cases, the default RSA
# authentication does not use this configuration. However, it is possible
# setup RSA to use ephemeral DH key exchange. In addition, ciphers with
# DSA keys always use ephemeral DH keys. This can be used to achieve
# forward secrecy. If the file is in DSA parameters format, it will be
# automatically converted into DH params.
# subject_match: Substring to be matched against the subject of the
# authentication server certificate. If this string is set, the server
# sertificate is only accepted if it contains this string in the subject.
# The subject string is in following format:
# /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
# Note: Since this is a substring match, this cannot be used securily to
# do a suffix match against a possible domain name in the CN entry. For
# such a use case, domain_suffix_match or domain_match should be used
# instead.
# altsubject_match: Semicolon separated string of entries to be matched against
# the alternative subject name of the authentication server certificate.
# If this string is set, the server sertificate is only accepted if it
# contains one of the entries in an alternative subject name extension.
# altSubjectName string is in following format: TYPE:VALUE
# Example: EMAIL:server@example.com
# Example: DNS:server.example.com;DNS:server2.example.com
# Following types are supported: EMAIL, DNS, URI
# domain_suffix_match: Constraint for server domain name. If set, this FQDN is
# used as a suffix match requirement for the AAAserver certificate in
# SubjectAltName dNSName element(s). If a matching dNSName is found, this
# constraint is met. If no dNSName values are present, this constraint is
# matched against SubjectName CN using same suffix match comparison.
#
# Suffix match here means that the host/domain name is compared one label
# at a time starting from the top-level domain and all the labels in
# domain_suffix_match shall be included in the certificate. The
# certificate may include additional sub-level labels in addition to the
# required labels.
#
# For example, domain_suffix_match=example.com would match
# test.example.com but would not match test-example.com.
# domain_match: Constraint for server domain name
# If set, this FQDN is used as a full match requirement for the
# server certificate in SubjectAltName dNSName element(s). If a
# matching dNSName is found, this constraint is met. If no dNSName
# values are present, this constraint is matched against SubjectName CN
# using same full match comparison. This behavior is similar to
# domain_suffix_match, but has the requirement of a full match, i.e.,
# no subdomains or wildcard matches are allowed. Case-insensitive
# comparison is used, so "Example.com" matches "example.com", but would
# not match "test.Example.com".
# phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
# (string with field-value pairs, e.g., "peapver=0" or
# "peapver=1 peaplabel=1")
# ‘peapver‘ can be used to force which PEAP version (0 or 1) is used.
# ‘peaplabel=1‘ can be used to force new label, "client PEAP encryption",
# to be used during key derivation when PEAPv1 or newer. Most existing
# PEAPv1 implementation seem to be using the old label, "client EAP
# encryption", and wpa_supplicant is now using that as the default value.
# Some servers, e.g., Radiator, may require peaplabel=1 configuration to
# interoperate with PEAPv1; see eap_testing.txt for more details.
# ‘peap_outer_success=0‘ can be used to terminate PEAP authentication on
# tunneled EAP-Success. This is required with some RADIUS servers that
# implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
# Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
# include_tls_length=1 can be used to force wpa_supplicant to include
# TLS Message Length field in all TLS messages even if they are not
# fragmented.
# sim_min_num_chal=3 can be used to configure EAP-SIM to require three
# challenges (by default, it accepts 2 or 3)
# result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
# protected result indication.
# ‘crypto_binding‘ option can be used to control PEAPv0 cryptobinding
# behavior:
# * 0 = do not use cryptobinding (default)
# * 1 = use cryptobinding if server supports it
# * 2 = require cryptobinding
# EAP-WSC (WPS) uses following options: pin=<Device Password> or
# pbc=1.
#
# For wired IEEE 802.1X authentication, "allow_canned_success=1" can be
# used to configure a mode that allows EAP-Success (and EAP-Failure)
# without going through authentication step. Some switches use such
# sequence when forcing the port to be authorized/unauthorized or as a
# fallback option if the authentication server is unreachable. By default,
# wpa_supplicant discards such frames to protect against potential attacks
# by rogue devices, but this option can be used to disable that protection
# for cases where the server/authenticator does not need to be
# authenticated.
# phase2: Phase2 (inner authentication with TLS tunnel) parameters
# (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
# "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS). "mschapv2_retry=0" can be
# used to disable MSCHAPv2 password retry in authentication failure cases.
#
# TLS-based methods can use the following parameters to control TLS behavior
# (these are normally in the phase1 parameter, but can be used also in the
# phase2 parameter when EAP-TLS is used within the inner tunnel):
# tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the
# TLS library, these may be disabled by default to enforce stronger
# security)
# tls_disable_time_checks=1 - ignore certificate validity time (this requests
# the TLS library to accept certificates even if they are not currently
# valid, i.e., have expired or have not yet become valid; this should be
# used only for testing purposes)
# tls_disable_session_ticket=1 - disable TLS Session Ticket extension
# tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used
# Note: If not set, this is automatically set to 1 for EAP-TLS/PEAP/TTLS
# as a workaround for broken authentication server implementations unless
# EAP workarounds are disabled with eap_workaround=0.
# For EAP-FAST, this must be set to 0 (or left unconfigured for the
# default value to be used automatically).
# tls_disable_tlsv1_0=1 - disable use of TLSv1.0
# tls_disable_tlsv1_1=1 - disable use of TLSv1.1 (a workaround for AAA servers
# that have issues interoperating with updated TLS version)
# tls_disable_tlsv1_2=1 - disable use of TLSv1.2 (a workaround for AAA servers
# that have issues interoperating with updated TLS version)
# tls_ext_cert_check=0 - No external server certificate validation (default)
# tls_ext_cert_check=1 - External server certificate validation enabled; this
# requires an external program doing validation of server certificate
# chain when receiving CTRL-RSP-EXT_CERT_CHECK event from the control
# interface and report the result of the validation with
# CTRL-RSP_EXT_CERT_CHECK.
#
# Following certificate/private key fields are used in inner Phase2
# authentication when using EAP-TTLS or EAP-PEAP.
# ca_cert2: File path to CA certificate file. This file can have one or more
# trusted CA certificates. If ca_cert2 and ca_path2 are not included,
# server certificate will not be verified. This is insecure and a trusted
# CA certificate should always be configured.
# ca_path2: Directory path for CA certificate files (PEM)
# client_cert2: File path to client certificate file
# private_key2: File path to client private key file
# private_key2_passwd: Password for private key file
# dh_file2: File path to DH/DSA parameters file (in PEM format)
# subject_match2: Substring to be matched against the subject of the
# authentication server certificate. See subject_match for more details.
# altsubject_match2: Semicolon separated string of entries to be matched
# against the alternative subject name of the authentication server
# certificate. See altsubject_match documentation for more details.
# domain_suffix_match2: Constraint for server domain name. See
# domain_suffix_match for more details.
#
# fragment_size: Maximum EAP fragment size in bytes (default 1398).
# This value limits the fragment size for EAP methods that support
# fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
# small enough to make the EAP messages fit in MTU of the network
# interface used for EAPOL. The default value is suitable for most
# cases.
#
# ocsp: Whether to use/require OCSP to check server certificate
# 0 = do not use OCSP stapling (TLS certificate status extension)
# 1 = try to use OCSP stapling, but not require response
# 2 = require valid OCSP stapling response
# 3 = require valid OCSP stapling response for all not-trusted
# certificates in the server certificate chain
#
# openssl_ciphers: OpenSSL specific cipher configuration
# This can be used to override the global openssl_ciphers configuration
# parameter (see above).
#
# erp: Whether EAP Re-authentication Protocol (ERP) is enabled
#
# EAP-FAST variables:
# pac_file: File path for the PAC entries. wpa_supplicant will need to be able
# to create this file and write updates to it when PAC is being
# provisioned or refreshed. Full path to the file should be used since
# working directory may change when wpa_supplicant is run in the
# background. Alternatively, a named configuration blob can be used by
# setting this to blob://<blob name>
# phase1: fast_provisioning option can be used to enable in-line provisioning
# of EAP-FAST credentials (PAC):
# 0 = disabled,
# 1 = allow unauthenticated provisioning,
# 2 = allow authenticated provisioning,
# 3 = allow both unauthenticated and authenticated provisioning
# fast_max_pac_list_len=<num> option can be used to set the maximum

# wpa_supplicant supports number of "EAP workarounds" to work around

# Station inactivity limit
#
# If a station does not send anything in ap_max_inactivity seconds, an
# empty data frame is sent to it in order to verify whether it is
# still in range. If this frame is not ACKed, the station will be
# disassociated and then deauthenticated. This feature is used to
# clear station table of old entries when the STAs move out of the
# range.
#
# The station can associate again with the AP if it is still in range;
# this inactivity poll is just used as a nicer way of verifying
# inactivity; i.e., client will not report broken connection because
# disassociation frame is not sent immediately without first polling
# the STA with a data frame.

# For detals, see IEEE Std 802.11ad-2012.
# Identifier of an FST Group the interface belongs to.
#fst_group_id=bond0
# Interface priority within the FST Group.
# Announcing a higher priority for an interface means declaring it more
# preferable for FST switch.

#fst_priority=100
# Default LLT value for this interface in milliseconds. The value used in case
