bgscan: Add global bgscan configuration

[mech_eap.git] / 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).
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.
# 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
# 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

# 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.
# The two engines that are supported currently are shown below:
# They are both from the opensc project (http://www.opensc.org/)
# By default no engines are loaded.

# configure the path to the pkcs11 module required by the pkcs11 engine
#pkcs11_module_path=/usr/lib/pkcs11/opensc-pkcs11.so

# Dynamic EAP methods
# If EAP methods were built dynamically as shared object files, they need to be
# loaded here before being used in the network blocks. By default, EAP methods
# are included statically in the build, so these lines are not needed
#load_dynamic_eap=/usr/lib/wpa_supplicant/eap_tls.so

#wps_nfc_dh_privkey: Hexdump of DH Private Key
#wps_nfc_dev_pw: Hexdump of Device Password

# 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

# 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

# Timeout in seconds to detect STA inactivity (default: 300 seconds)
#
# This timeout value is used in P2P GO mode to clean up
# inactive stations.
#p2p_go_max_inactivity=300

# 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. 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.
#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.

# 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:
#
# 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.
#
# for example:
#
#cred={
#       realm="example.com"
#       username="user@example.com"
#       password="password"
#       ca_cert="/etc/wpa_supplicant/ca.pem"
#       domain="example.com"
#}
#
#cred={
#       imsi="310026-000000000"
#       milenage="90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82"

# Hotspot 2.0
# hs20=1

# 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 key_mgmt=WPA-NONE (fixed group key TKIP/CCMP). 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.
#
# 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"
#
# 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.
#
# proto: list of accepted protocols
# WPA = WPA/IEEE 802.11i/D3.0
# RSN = WPA2/IEEE 802.11i (also WPA2 can be used as an alias for RSN)
# If not set, this defaults to: WPA RSN
#
# key_mgmt: list of accepted authenticated key management protocols
# WPA-PSK = WPA pre-shared key (this requires 'psk' field)
# WPA-EAP = WPA using EAP authentication
# IEEE8021X = IEEE 802.1X using EAP authentication and (optionally) dynamically
#       generated WEP keys
# NONE = WPA is not used; plaintext or static WEP could be used
# WPA-PSK-SHA256 = Like WPA-PSK but using stronger SHA256-based algorithms
# WPA-EAP-SHA256 = Like WPA-EAP but using stronger SHA256-based algorithms
# 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:

# 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.

#
# 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)

#       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
# 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
# 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.
# 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)
#
# 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_workarounds=0.
#       For EAP-FAST, this must be set to 0 (or left unconfigured for the
#       default value to be used automatically).
#
# 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.
# altsubject_match2: Substring to be matched against the alternative subject
#       name of the authentication server certificate.
#
# 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
#
# 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
#               number of PAC entries to store in a PAC list (default: 10)
#       fast_pac_format=binary option can be used to select binary format for
#               storing PAC entries in order to save some space (the default
#               text format uses about 2.5 times the size of minimal binary
#               format)
#
# wpa_supplicant supports number of "EAP workarounds" to work around
# interoperability issues with incorrectly behaving authentication servers.
# These are enabled by default because some of the issues are present in large
# number of authentication servers. Strict EAP conformance mode can be
# configured by disabling workarounds with eap_workaround=0.

# 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.
# default: 300 (i.e., 5 minutes)
#ap_max_inactivity=300

# DTIM period in Beacon intervals for AP mode (default: 2)

# disable_ht: Whether HT (802.11n) should be disabled.
# 0 = HT enabled (if AP supports it)
# 1 = HT disabled
#
# disable_ht40: Whether HT-40 (802.11n) should be disabled.
# 0 = HT-40 enabled (if AP supports it)
# 1 = HT-40 disabled
#
# disable_sgi: Whether SGI (short guard interval) should be disabled.
# 0 = SGI enabled (if AP supports it)
# 1 = SGI disabled
#
# ht_mcs:  Configure allowed MCS rates.
#  Parsed as an array of bytes, in base-16 (ascii-hex)
# ht_mcs=""                                   // Use all available (default)

# ht_mcs="0xff ff 00 00 00 00 00 00 00 00 "   // Use MCS 0-15 only
#
# disable_max_amsdu:  Whether MAX_AMSDU should be disabled.
# -1 = Do not make any changes.
# 0  = Enable MAX-AMSDU if hardware supports it.
# 1  = Disable AMSDU
#
# ampdu_density:  Allow overriding AMPDU density configuration.
#  Treated as hint by the kernel.
# -1 = Do not make any changes.
# 0-3 = Set AMPDU density (aka factor) to specified value.

# disable_vht: Whether VHT should be disabled.
# 0 = VHT enabled (if AP supports it)
# 1 = VHT disabled
#
# vht_capa: VHT capabilities to set in the override
# vht_capa_mask: mask of VHT capabilities
#
# vht_rx_mcs_nss_1/2/3/4/5/6/7/8: override the MCS set for RX NSS 1-8
# vht_tx_mcs_nss_1/2/3/4/5/6/7/8: override the MCS set for TX NSS 1-8
#  0: MCS 0-7
