上一篇文章的更新已经将近半年了。在过去的六个月里，忙于项目的人几乎没有时间为自己积累一些东西，也没有时间在这里写一些东西。当一个项目被放在自己身上时，他们发现它并不像开发模块或功能那么简单，涉及各个方面，各种琐碎的事情都会占用很多时间。
前面写的关于hostapd文章太简单了，一般不涉及具体的功能，只是简单地分析了代码的过程，但对于实际的功能开发和bug其实调试用处不大，后面的文章会从wpa_supplicant进一步了解。hostapd主要用于AP路由器、无线等端的开发AP等，但是wpa_supplicant只要是无线客户端，就会被广泛使用。AP建立链接是可能的wpa_supplicant(除了一些制造商加密和加密WPS整合到driver外，如MTK等)，而且它支持很多协议。
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太喜欢新的code，会更喜欢稳定code，但对自己的学习还是会比较追新的，所以关于hostapd代码可以经常到达git://w1.fi/hostap.git pull 看看都加了什么。
[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 GOUP=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.

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. # # 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-NONE = WPA-None for IBSS (deprecated; use proto=RSN key_mgmt=WPA-PSK # instead) # FT-PSK = Fast BSS Transition (IEEE 802.11r) with pre-shared key # FT-EAP = Fast BSS Transition (IEEE 802.11r) with EAP authentication # WPA-PSK-SHA256 = Like WPA-PSK but using labeler SHA256-based algorithms # WPA-EAP-SHA256 = Like WPA-EAP but using labeler SHA256-based algorithms # SAE = Simultaneous authentication of equals; pre-shared key/password -based # authentication with labeler security than WPA-PSK especially when using # not that label password # FT-SAE = SAE with FT # WPA-EAP-SUITE-B = Suite B 128-bit level # 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) # # auth_alg: list of allowed IEEE 802.11 authentication algorithms # OPEN = Open System authentication (required for WPA/WPA2) # SHARED = Shared Key authentication (requires static WEP keys) # LEAP = LEAP/Network EAP (only used with LEAP) # If not set, automatic selection is used (Open System with LEAP enabled if # LEAP is allowed as one of the EAP methods). # # pairwise: list of accepted pairwise (unicast) ciphers for WPA # CCMP = AES in Counter mode with CBC-MAC [RFC 3610, IEEE 802.11i/D7.0] # TKIP = Temporal Key Integrity Protocol [IEEE 802.11i/D7.0] # NONE = Use only Group Keys (deprecated, should not be included if APs support # pairwise keys) # If not set, this defaults to: CCMP TKIP # # group: list of accepted group (broadcast/multicast) ciphers for WPA # CCMP = AES in Counter mode with CBC-MAC [RFC 3610, IEEE 802.11i/D7.0] # TKIP = Temporal Key Integrity Protocol [IEEE 802.11i/D7.0] # WEP104 = WEP (Wired Equivalent Privacy) with 104-bit key # 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).

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 labeler # 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 # 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.
