wpa_supplicant implementation is divided into number of independent
modules. Core code includes functionality for controlling the network
selection, association, and configuration. Independent modules include
WPA code (key handshake, PMKSA caching, pre-authentication), EAPOL
state machine, and EAP state machine and methods. In addition, there
are number of separate files for generic helper functions.
Both WPA and EAPOL/EAP state machines can be used separately in other
programs than wpa_supplicant. As an example, the included test
programs eapol_test and preauth_test are using these modules.
\ref driver_wrapper "Driver interface API" is defined in \ref driver.h and

/**
\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
All hardware and driver dependent functionality is in separate C files
that implement defined wrapper functions. Other parts
of the wpa_supplicant are designed to be hardware, driver, and operating
system independent.
Driver wrappers need to implement whatever calls are used in the
target operating system/driver for controlling wireless LAN
devices. As an example, in case of Linux, these are mostly some glue
code and ioctl() calls and netlink message parsing for Linux Wireless
Extensions (WE). Since features required for WPA were added only recently to
Linux Wireless Extensions (in version 18), some driver specific code is used
in number of driver interface implementations. These driver dependent parts
can be replaced with generic code in \ref driver_wext.c once the target driver
includes full support for WE-18. After that, all Linux drivers, at
least in theory, could use the same driver wrapper code.
A driver wrapper needs to implement some or all of the functions
defined in \ref driver.h. These functions are registered by filling struct
\ref wpa_driver_ops with function pointers. Hardware independent parts of
wpa_supplicant will call these functions to control the driver/wlan
card. In addition, support for driver events is required. The event
callback function, \ref wpa_supplicant_event(), and its parameters are
documented in \ref driver.h. In addition, a pointer to the 'struct
\ref wpa_driver_ops' needs to be registered in \ref drivers.c file.
When porting to other operating systems, the driver wrapper should be
modified to use the native interface of the target OS. It is possible
that some extra requirements for the interface between the driver
wrapper and generic wpa_supplicant code are discovered during porting
to a new operating system. These will be addressed on case by case
basis by modifying the interface and updating the other driver
wrappers for this. The goal is to avoid changing this interface
without very good reasons in order to limit the number of changes
needed to other wrappers and hardware independent parts of
wpa_supplicant. When changes are required, recommended way is to
make them in backwards compatible way that allows existing driver
interface implementations to be compiled without any modification.
Generic Linux Wireless Extensions functions are implemented in
\ref driver_wext.c. All Linux driver wrappers can use these when the kernel
driver supports the generic ioctl()s and wireless events. Driver
specific functions are implemented in separate C files, e.g.,
\ref driver_hostap.c. These files need to define struct \ref wpa_driver_ops
entry that will be used in \ref wpa_supplicant.c when calling driver
functions. struct \ref wpa_driver_ops entries are registered in \ref drivers.c.
In general, it is likely to be useful to first take a look at couple
of driver interface examples before starting on implementing a new
one. \ref driver_hostap.c and \ref driver_wext.c include a complete
implementation for Linux drivers that use wpa_supplicant-based control
of WPA IE and roaming. \ref driver_ndis.c (with help from \ref driver_ndis_.c)
is an example of a complete interface for Windows NDIS interface for
drivers that generate WPA IE themselves and decide when to roam. These
example implementations include full support for all security modes.
\section driver_req Driver requirements for WPA
WPA introduces new requirements for the device driver. At least some
of these need to be implemented in order to provide enough support for
wpa_supplicant.
\subsection driver_tkip_ccmp TKIP/CCMP
WPA requires that the pairwise cipher suite (encryption algorithm for
unicast data packets) is TKIP or CCMP. These are new encryption
protocols and thus, the driver will need to be modified to support
them. Depending on the used wlan hardware, some parts of these may be
implemented by the hardware/firmware.
Specification for both TKIP and CCMP is available from IEEE (IEEE
802.11i amendment). Fully functional, hardware independent
implementation of both encryption protocols is also available in Host
AP driver (driver/modules/hostap_{tkip,ccmp}.c). In addition, Linux 2.6
kernel tree has generic implementations for WEP, TKIP, and CCMP that can
be used in Linux drivers.
The driver will also need to provide configuration mechanism to allow
user space programs to configure TKIP and CCMP. Linux Wireless Extensions
v18 added support for configuring these algorithms and
individual/non-default keys. If the target kernel does not include WE-18,
private ioctls can be used to provide similar functionality.
\subsection driver_roaming Roaming control and scanning support
wpa_supplicant can optionally control AP selection based on the
information received from Beacon and/or Probe Response frames
(ap_scan=1 mode in configuration). This means that the driver should
support external control for scan process. In case of Linux, use of
new Wireless Extensions scan support (i.e., 'iwlist wlan0 scan') is
recommended. The current driver wrapper (\ref driver_wext.c) uses this for
scan results.
Scan results must also include the WPA information element. Support for
this was added in WE-18. With older versions, a custom event can be used
to provide the full WPA IE (including element id and length) as a hex
string that is included in the scan results.
wpa_supplicant needs to also be able to request the driver to
associate with a specific BSS. Current Host AP driver and matching
\ref driver_hostap.c wrapper uses following sequence for this
request. Similar/identical mechanism should be usable also with other
drivers.
- set WPA IE for AssocReq with private ioctl
- set SSID with SIOCSIWESSID
- set channel/frequency with SIOCSIWFREQ
- set BSSID with SIOCSIWAP
(this last ioctl will trigger the driver to request association)
\subsection driver_wpa_ie WPA IE generation
wpa_supplicant selects which cipher suites and key management suites
are used. Based on this information, it generates a WPA IE. This is
provided to the driver interface in the associate call. This does not
match with Windows NDIS drivers which generate the WPA IE
themselves.
wpa_supplicant allows Windows NDIS-like behavior by providing the
selected cipher and key management suites in the associate call. If
the driver generates its own WPA IE and that differs from the one
generated by wpa_supplicant, the driver has to inform wpa_supplicant
about the used WPA IE (i.e., the one it used in (Re)Associate
Request). This notification is done using EVENT_ASSOCINFO event (see
\ref driver.h). wpa_supplicant is normally configured to use
ap_scan=2 mode with drivers that control WPA IE generation and roaming.
\subsection driver_events Driver events
wpa_supplicant needs to receive event callbacks when certain events
occur (association, disassociation, Michael MIC failure, scan results
available, PMKSA caching candidate). These events and the callback
details are defined in \ref driver.h (\ref wpa_supplicant_event() function
and enum \ref wpa_event_type).
On Linux, association and disassociation can use existing Wireless
Extensions event that is reporting new AP with SIOCGIWAP
event. Similarly, completion of a scan can be reported with SIOCGIWSCAN
event.
Michael MIC failure event was added in WE-18. Older versions of Wireless
Extensions will need to use a custom event. Host AP driver used a custom
event with following contents: MLME-MICHAELMICFAILURE.indication(keyid=#
broadcast/unicast addr=addr2). This is the recommended format until
the driver can be moved to use WE-18 mechanism.
\subsection driver_wext_summary Summary of Linux Wireless Extensions use
AP selection depends on ap_scan configuration:
ap_scan=1:
- wpa_supplicant requests scan with SIOCSIWSCAN
- driver reports scan complete with wireless event SIOCGIWSCAN
- wpa_supplicant reads scan results with SIOCGIWSCAN (multiple call if
a larger buffer is needed)
- wpa_supplicant decides which AP to use based on scan results
- wpa_supplicant configures driver to associate with the selected BSS
(SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWFREQ,
SIOCSIWESSID, SIOCSIWAP)
ap_scan=2:
- wpa_supplicant configures driver to associate with an SSID
(SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWESSID)
After this, both modes use similar steps:
- optionally (or required for drivers that generate WPA/RSN IE for
(Re)AssocReq), driver reports association parameters (AssocReq IEs)
with wireless event IWEVASSOCREQIE (and optionally IWEVASSOCRESPIE)
- driver reports association with wireless event SIOCGIWAP
- wpa_supplicant takes care of EAPOL frame handling (validating
information from associnfo and if needed, from scan results if WPA/RSN
IE from the Beacon frame is not reported through associnfo)

/**
\page eap_peer_module EAP peer implementation
Extensible Authentication Protocol (EAP) is an authentication framework
defined in RFC 3748. wpa_supplicant uses a separate code module for EAP
peer implementation. This module was designed to use only a minimal set
of direct function calls (mainly, to debug/event functions) in order for
it to be usable in other programs. The design of the EAP
implementation is based loosely on RFC 4137. The state machine is
defined in this RFC and so is the interface between the peer state
machine and methods. As such, this RFC provides useful information for
understanding the EAP peer implementation in wpa_supplicant.
Some of the terminology used in EAP state machine is referring to
EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
layer being IEEE 802.1X if EAP module is built for other programs than
wpa_supplicant. These terms should be understood to refer to the
lower layer as defined in RFC 4137.
\section adding_eap_methods Adding EAP methods
Each EAP method is implemented as a separate module, usually as one C
file named eap_<name of the method>.c, e.g., \ref eap_md5.c. All EAP
methods use the same interface between the peer state machine and
method specific functions. This allows new EAP methods to be added
without modifying the core EAP state machine implementation.
New EAP methods need to be registered by adding them into the build
(Makefile) and the EAP method registration list in the
\ref eap_peer_register_methods() function of \ref eap_methods.c. Each EAP
method should use a build-time configuration option, e.g., EAP_TLS, in
order to make it possible to select which of the methods are included
in the build.
EAP methods must implement the interface defined in \ref eap_i.h. struct
\ref eap_method defines the needed function pointers that each EAP method
must provide. In addition, the EAP type and name are registered using
this structure. This interface is based on section 4.4 of RFC 4137.
It is recommended that the EAP methods would use generic helper
functions, \ref eap_msg_alloc() and \ref eap_hdr_validate() when processing
messages. This allows code sharing and can avoid missing some of the
needed validation steps for received packets. In addition, these
functions make it easier to change between expanded and legacy EAP
header, if needed.
When adding an EAP method that uses a vendor specific EAP type
(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
must be registered by passing vendor id instead of EAP_VENDOR_IETF to
\ref eap_peer_method_alloc(). These methods must not try to emulate
expanded types by registering a legacy EAP method for type 254. See
\ref eap_vendor_test.c for an example of an EAP method implementation that
is implemented as an expanded type.
\section used_eap_library Using EAP implementation as a library
The Git repository has an eap_example directory that contains an
example showing how EAP peer and server code from wpa_supplicant and
hostapd can be used as a library. The example program initializes both
an EAP server and an EAP peer entities and then runs through an
EAP-PEAP/MSCHAPv2 authentication.
\ref eap_example_peer.c shows the initialization and glue code needed to
control the EAP peer implementation. \ref eap_example_server.c does the
same for EAP server. \ref eap_example.c is an example that ties in both the
EAP server and client parts to allow an EAP authentication to be
shown.
In this example, the EAP messages are passed between the server and
the peer are passed by direct function calls within the same process.
In practice, server and peer functionalities would likely reside in
separate devices and the EAP messages would be transmitted between the
devices based on an external protocol. For example, in IEEE 802.11
uses IEEE 802.1X EAPOL state machines to control the transmission of
EAP messages and WiMax supports optional PMK EAP authentication
mechanism that transmits EAP messages as defined in IEEE 802.16e.
The EAP library links in number of helper functions from \ref src/utils and
\ref src/crypto directories. Most of these are suitable as-is, but it may
be desirable to replace the debug output code in \ref src/utils/wpa_debug.c
by dropping this file from the library and re-implementing the
functions there in a way that better fits in with the main
application.

/**
\page eap_server_module EAP server implementation
Extensible Authentication Protocol (EAP) is an authentication framework
defined in RFC 3748. hostapd uses a separate code module for EAP server
implementation. This module was designed to use only a minimal set of
direct function calls (mainly, to debug/event functions) in order for
it to be usable in other programs. The design of the EAP
implementation is based loosely on RFC 4137. The state machine is
defined in this RFC and so is the interface between the server state
machine and methods. As such, this RFC provides useful information for
understanding the EAP server implementation in hostapd.
Some of the terminology used in EAP state machine is referring to
EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
layer being IEEE 802.1X if EAP module is built for other programs than
wpa_supplicant. These terms should be understood to refer to the
lower layer as defined in RFC 4137.
\section adding_eap_methods Adding EAP methods
Each EAP method is implemented as a separate module, usually as one C
file named eap_server_<name of the method>.c, e.g., \ref eap_server_md5.c. All EAP
methods use the same interface between the server state machine and
method specific functions. This allows new EAP methods to be added
without modifying the core EAP state machine implementation.
New EAP methods need to be registered by adding them into the build
(Makefile) and the EAP method registration list in the
\ref eap_server_register_methods() function of \ref eap_server_methods.c. Each EAP
method should use a build-time configuration option, e.g., EAP_TLS, in
order to make it possible to select which of the methods are included
in the build.
EAP methods must implement the interface defined in \ref eap_i.h. struct
\ref eap_method defines the needed function pointers that each EAP method
must provide. In addition, the EAP type and name are registered using
this structure. This interface is based on section 4.4 of RFC 4137.
It is recommended that the EAP methods would use generic helper
functions, \ref eap_msg_alloc() and \ref eap_hdr_validate() when processing
messages. This allows code sharing and can avoid missing some of the
needed validation steps for received packets. In addition, these
functions make it easier to change between expanded and legacy EAP
header, if needed.
When adding an EAP method that uses a vendor specific EAP type
(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
must be registered by passing vendor id instead of EAP_VENDOR_IETF to
\ref eap_server_method_alloc(). These methods must not try to emulate
expanded types by registering a legacy EAP method for type 254. See
\ref eap_server_vendor_test.c for an example of an EAP method implementation that
is implemented as an expanded type.

/**
\page hostapd_ctrl_iface_page hostapd control interface
hostapd implements a control interface that can be used by
external programs to control the operations of the hostapd
daemon and to get status information and event notifications. There is
a small C library, in a form of a single C file, \ref wpa_ctrl.c, that
provides helper functions to facilitate the use of the control
interface. External programs can link this file into them and then use
the library functions documented in \ref wpa_ctrl.h to interact with
wpa_supplicant. This library can also be used with C++. \ref hostapd_cli.c
is an example program using this library.
There are multiple mechanisms for inter-process communication. For
example, Linux version of hostapd is using UNIX domain sockets for the
control interface. The use of the functions defined in \ref wpa_ctrl.h can
be used to hide the details of the used IPC from external programs.
\section using_ctrl_iface Using the control interface
External programs, e.g., a GUI or a configuration utility, that need to
communicate with hostapd should link in \ref wpa_ctrl.c. This
allows them to use helper functions to open connection to the control
interface with \ref wpa_ctrl_open() and to send commands with
\ref wpa_ctrl_request().
hostapd uses the control interface for two types of communication:
commands and unsolicited event messages. Commands are a pair of
messages, a request from the external program and a response from
hostapd. These can be executed using \ref wpa_ctrl_request().
Unsolicited event messages are sent by hostapd to the control
interface connection without specific request from the external program
for receiving each message. However, the external program needs to
attach to the control interface with \ref wpa_ctrl_attach() to receive these
unsolicited messages.
If the control interface connection is used both for commands and
unsolicited event messages, there is potential for receiving an
unsolicited message between the command request and response.
\ref wpa_ctrl_request() caller will need to supply a callback, msg_cb,
for processing these messages. Often it is easier to open two
control interface connections by calling \ref wpa_ctrl_open() twice and
then use one of the connections for commands and the other one for
unsolicited messages. This way command request/response pairs will
not be broken by unsolicited messages. \ref wpa_cli.c is an example of how
to use only one connection for both purposes and wpa_gui demonstrates
how to use two separate connections.
Once the control interface connection is not needed anymore, it should
be closed by calling \ref wpa_ctrl_close(). If the connection was used for
unsolicited event messages, it should be first detached by calling
\ref wpa_ctrl_detach().
\section ctrl_iface_cmds Control interface commands
Following commands can be used with \ref wpa_ctrl_request():
\subsection ctrl_iface_PING PING
This command can be used to test whether hostapd is replying
to the control interface commands. The expected reply is \c PONG if the
connection is open and hostapd is processing commands.

/**
\mainpage Developers' documentation for wpa_supplicant and hostapd
The goal of this documentation and comments in the source code is to
give enough information for other developers to understand how
wpa_supplicant and hostapd have been implemented, how they can be
modified, how new drivers can be supported, and how the source code
can be ported to other operating systems. If any information is
missing, feel free to contact Jouni Malinen <j@w1.fi> for more
information. Contributions as patch files are also very welcome at the
same address. Please note that this software is licensed under the
BSD license (the one with advertisement clause removed). All
contributions to wpa_supplicant and hostapd are expected to use
compatible licensing terms.
The source code and read-only access to the combined wpa_supplicant
and hostapd Git repository is available from the project home page at
http://w1.fi/wpa_supplicant/. This developers' documentation is also
available as a PDF file from
http://w1.fi/wpa_supplicant/wpa_supplicant-devel.pdf .
\section _wpa_supplicant wpa_supplicant
wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with
support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE
802.1X/WPA component that is used in the client stations. It
implements key negotiation with a WPA Authenticator and it can optionally
control roaming and IEEE 802.11 authentication/association of the wlan
driver.
The design goal for wpa_supplicant was to use hardware, driver, and
OS independent, portable C code for all WPA functionality. The source
code is divided into separate C files as shown on the \ref
code_structure "code structure page". All hardware/driver specific
functionality is in separate files that implement a \ref
driver_wrapper "well-defined driver API". Information about porting
to different target boards and operating systems is available on
the \ref porting "porting page".
EAPOL (IEEE 802.1X) state machines are implemented as a separate
module that interacts with \ref eap_peer_module "EAP peer implementation".
In addition to programs aimed at normal production use,
wpa_supplicant source tree includes number of \ref testing_tools
"testing and development tools" that make it easier to test the
programs without having to setup a full test setup with wireless
cards. These tools can also be used to implement automatic test
suites.
wpa_supplicant implements a
\ref ctrl_iface_page "control interface" that can be used by
external programs to control the operations of the wpa_supplicant
daemon and to get status information and event notifications. There is
a small C library that provides helper functions to facilitate the use of the
control interface. This library can also be used with C++.

\section _hostapd hostapd
hostapd includes IEEE 802.11 access point management (authentication /
association), IEEE 802.1X/WPA/WPA2 Authenticator, EAP server, and
RADIUS authentication server functionality. It can be build with
various configuration option, e.g., a standalone AP management
solution or a RADIUS authentication server with support for number of
EAP methods.
The design goal for hostapd was to use hardware, driver, and
OS independent, portable C code for all WPA functionality. The source
code is divided into separate C files as shown on the \ref
code_structure "code structure page". All hardware/driver specific
functionality is in separate files that implement a \ref
driver_wrapper "well-defined driver API". Information about porting
to different target boards and operating systems is available on
the \ref porting "porting page".
EAPOL (IEEE 802.1X) state machines are implemented as a separate
module that interacts with \ref eap_server_module "EAP server implementation".
Similarly, RADIUS authentication server is in its own separate module.
Both IEEE 802.1X and RADIUS authentication server can use EAP server
functionality.
hostapd implements a \ref hostapd_ctrl_iface_page "control interface"
that can be used by external programs to control the operations of the
hostapdt daemon and to get status information and event notifications.
There is a small C library that provides helper functions to facilitate
the use of the control interface. This library can also be used with
C++.

/**
\page p2p Wi-Fi Direct - P2P module
Wi-Fi Direct functionality is implemented any many levels in the WLAN
stack from low-level driver operations to high-level GUI design. This
document covers the parts that can be user by wpa_supplicant. However,
it should be noted that alternative designs are also possible, so some
of the functionality may reside in other components in the system.
The driver (or WLAN firmware/hardware) is expected to handle low-level
operations related to P2P Power Management and channel scheduling. In
addition, support for virtual network interface and data frame
processing is done inside the driver. Configuration for these
low-level operations is defined in the driver interface:
src/drivers/driver.h. This defines both the commands and events used to
interact with the driver.
P2P module implements higher layer functionality for management P2P
groups. It takes care of Device Discovery, Service Discovery, Group
Owner Negotiation, P2P Invitation. In addition, it maintains
information about neighboring P2P Devices. This module could be used
in designs that do not use wpa_supplicant and it could also reside
inside the driver/firmware component. P2P module API is defined in
\ref src/p2p/p2p.h.
Provisioning step of Group Formation is implemented using WPS
(\ref src/wps/wps.h).
wpa_supplicant includes code in interact with both the P2P module
(\ref wpa_supplicant/p2p_supplicant.c) and WPS
(\ref wpa_supplicant/wps_supplicant.c). The driver operations are passed
through these files, i.e., core P2P or WPS code does not interact
directly with the driver interface.
\section p2p_arch P2P architecture
P2P functionality affects many areas of the system architecture. This
section shows couple of examples on the location of main P2P
components. In the diagrams below, green arrows are used to show
communication paths from the P2P module to upper layer management
functionality and all the way to a GUI that user could use to manage
P2P connections. Blue arrows show the path taken for lower layer
operations. Glue code is used to bind the P2P module API to the rest
of the system to provide access both towards upper and lower layer
functionality.
\subsection p2p_arch_mac80211 P2P architecture with Linux/mac80211/ath9k
An architecture where the P2P module resides inside the
wpa_supplicant process is used with Linux mac80211-based drivers,
e.g., ath9k. The following diagram shows the main components related
to P2P functionality in such an architecture.
\image html p2p_arch.png "P2P module within wpa_supplicant"

\subsection p2p_arch_umac P2P architecture with UMAC
The following diagram shows the main components related to P2P
functionality in an architecture where the P2P module resides inside
the kernel IEEE 802.11 stack (UMAC in the figure).
\image html p2p_arch2.png "P2P module in kernel
\image latex p2p_arch2.eps "P2P module in kernel" width=15cm
\section p2p_module P2P module
P2P module manages discovery and group formation with a single state
machine, i.e., only a single operation per device can be in progress
at any given time. The following diagram describes the P2P state
machine. For clarity, it does not include state transitions on
operation timeouts to the IDLE state. The states that are marked with
dotted ellipse are listed for clarity to describe the protocol
functionality for Device Discovery phase, but are not used in the
implementation (the SEARCH state is used to manage the initial Scan
and the alternating Listen and Search states within Find).

\image latex p2p_sm.eps "P2P module state machine" width=15cm
\subsection p2p_module_api P2P module API
P2P module API is defined in \ref src/p2p/p2p.h. The API consists of
functions for requesting operations and for providing event
notifications. Similar set of callback functions are configured with
struct p2p_config to provide callback functions that P2P module can
use to request operations and to provide event notifications. In
addition, there are number of generic helper functions that can be
used for P2P related operations.
These are the main functions for an upper layer management entity to
request P2P operations:
- \ref p2p_find()
- \ref p2p_stop_find()
- \ref p2p_listen()
- \ref p2p_connect()
- \ref p2p_reject()
- \ref p2p_prov_disc_req()
- \ref p2p_sd_request()
- \ref p2p_sd_cancel_request()
- \ref p2p_sd_response()
- \ref p2p_sd_service_update()
- \ref p2p_invite()
These are the main callback functions for P2P module to provide event
notifications to the upper layer management entity:
- \ref p2p_config::dev_found()
- \ref p2p_config::go_neg_req_rx()
- \ref p2p_config::go_neg_completed()
- \ref p2p_config::sd_request()
- \ref p2p_config::sd_response()
- \ref p2p_config::prov_disc_req()
- \ref p2p_config::prov_disc_resp()
- \ref p2p_config::invitation_process()
- \ref p2p_config::invitation_received()
- \ref p2p_config::invitation_result()
The P2P module uses following functions to request lower layer driver
operations:
- \ref p2p_config::p2p_scan()
- \ref p2p_config::send_probe_resp()
- \ref p2p_config::send_action()
- \ref p2p_config::send_action_done()
- \ref p2p_config::start_listen()
- \ref p2p_config::stop_listen()
Events from lower layer driver operations are delivered to the P2P
module with following functions:
- \ref p2p_probe_req_rx()
- \ref p2p_rx_action()
- \ref p2p_scan_res_handler()
- \ref p2p_scan_res_handled()
- \ref p2p_send_action_cb()
- \ref p2p_listen_cb()
In addition to the per-device state, the P2P module maintains
per-group state for group owners. This is initialized with a call to
p2p_group_init() when a group is created and deinitialized with
p2p_group_deinit(). The upper layer GO management entity uses
following functions to interact with the P2P per-group state:
- \ref p2p_group_notif_assoc()
- \ref p2p_group_notif_disassoc()
- \ref p2p_group_notif_formation_done()
- \ref p2p_group_match_dev_type()
The P2P module will use following callback function to update P2P IE
for GO Beacon and Probe Response frames:
- \ref p2p_group_config::ie_update()
\section p2p_driver P2P driver operations (low-level interface)
The following driver wrapper functions are needed for P2P in addition
to the standard station/AP mode operations when the P2P module resides
within wpa_supplicant:
- \ref wpa_driver_ops::if_add()
- \ref wpa_driver_ops::if_remove()
- \ref wpa_driver_ops::remain_on_channel()
- \ref wpa_driver_ops::cancel_remain_on_channel()
- \ref wpa_driver_ops::send_action()
- \ref wpa_driver_ops::probe_req_report()
The following driver wrapper events are needed for P2P in addition to
the standard station/AP mode events when the P2P module resides within
wpa_supplicant:
- \ref wpa_event_type::EVENT_RX_MGMT
- \ref wpa_event_type::EVENT_REMAIN_ON_CHANNEL
- \ref wpa_event_type::EVENT_CANCEL_REMAIN_ON_CHANNEL
- \ref wpa_event_type::EVENT_RX_PROBE_REQ
\section p2p_go_neg P2P device discovery and group formation
This section shows an example sequence of operations that can be used
to implement P2P device discovery and group formation. The function
calls are described based on the P2P module API. The exact design for
the glue code outside the P2P module depends on the architecture used
in the system.
An upper layer management entity starts P2P device discovery by
calling \ref p2p_find(). The P2P module start the discovery by requesting a
full scan to be completed by calling \ref p2p_config::p2p_scan(). Results
from the scan will be reported by calling \ref p2p_scan_res_handler() and
after last result, the scan result processing is terminated with a
call to \ref p2p_scan_res_handled(). The P2P peers that are found during
the full scan are reported with the \ref p2p_config::dev_found() callback.
After the full scan, P2P module start alternating between Listen and
Search states until the device discovery operation times out or
terminated, e.g., with a call to \ref p2p_stop_find().
When going into the Listen state, the P2P module requests the driver
to be configured to be awake on the listen channel with a call to
\ref p2p_config::start_listen(). The glue code using the P2P module may
implement this, e.g., by using remain-on-channel low-level driver
functionality for off-channel operation. Once the driver is available
on the requested channel, notification of this is delivered by calling
\ref p2p_listen_cb(). The Probe Request frames that are received during the
Listen period are delivered to the P2P module by calling
\ref p2p_config::p2p_probe_req_rx() and P2P module request a response to
these to be sent by using \ref p2p_config::send_probe_resp() callback
function. If a group owner negotiation from another P2P device is
received during the device discovery phase, that is indicated to the
upper layer code with the \ref p2p_config::go_neg_req_tx() callback.
The Search state is implemented by using the normal scan interface,
i.e., the P2P module will call \ref p2p_config::p2p_scan() just like in the
full scan phase described. Similarly, scan results from the search
operation will be delivered to the P2P module using the
\ref p2p_scan_res_handler() and \ref p2p_scan_res_handled() functions.
Once the upper layer management entity has found a peer with which it
wants to connect by forming a new group, it initiates group owner
negotiation by calling \ref p2p_connect(). Before doing this, the upper
layer code is responsible for asking the user to provide the PIN to be
used during the provisioning step with the peer or the push button
press for PBC mode. The glue code will need to figure out the intended
interface address for the group before group owner negotiation can be
started.
Optional Provision Discovery mechanism can be used to request the peer
to display a PIN for the local device to enter (and vice versa). Upper
layer management entity can request the specific mechanism by calling
\ref p2p_prov_disc_req(). The response to this will be reported with the
\ref p2p_config::prov_disc_resp() callback. If the peer device started
Provision Discovery, an accepted request will be reported with the
\ref p2p_config::prov_disc_req() callback. The P2P module will
automatically accept the Provision Discovery for display and keypad
methods, but it is up to the upper layer manegement entity to actually
generate the PIN and to configure it with following \ref p2p_connect() call
to actually authorize the connection.
The P2P module will use \ref p2p_config::send_action() callback to request
lower layer code to transmit an Action frame during group owner
negotiation. \ref p2p_send_action_cb() is used to report the result of
transmission. If the peer is not reachable, the P2P module will try to
find it by alternating between Action frame send and Listen
states. The Listen state for this phase will be used similarly to the
Listen state during device discovery as described above.
Once the group owner negotiation has been completed, its results will
be reported with the \ref p2p_config::go_neg_completed() callback. The
upper layer management code or the glue code using the P2P module API
is responsible for creating a new group interface and starting
provisioning step at this point by configuring WPS Registrar or
Enrollee functionality based on the reported group owner negotiation
results. The upper layer code is also responsible for timing out WPS
provisioning if it cannot be completed in 15 seconds.
Successful completion of the WPS provisioning is reported with a call
to \ref p2p_wps_success_cb(). The P2P module will clear its group formation
state at this point and allows new group formation attempts to be
started. The upper layer management code is responsible for configuring
the GO to accept associations from devices and the client to connect to
the GO with the provisioned credentials. GO is also responsible for
calling \ref p2p_group_notif_formation_done() as described below.
If the WPS provisioning step fails or times out, this is reported with
a call to \ref p2p_group_formation_failed(). The P2P module will clear its
group formation state at this point and allows new group formation
attempts to be started. The upper layer management code is responsible
for removing the group interface for the failed group.
\section p2p_sd P2P service discovery
P2P protocol includes service discovery functionality that can be used
to discover which services are provided by the peers before forming a
group. This leverages the Generic Advertisement Service (GAS) protocol
from IEEE 802.11u and P2P vendor-specific contents inside the Native
GAS messages.
The P2P module takes care of GAS encapsulation, fragmentation, and
actual transmission and reception of the Action frames needed for
service discovery. The user of the P2P module is responsible for
providing P2P specific Service Request TLV(s) for queries and Service
Response TLV(s) for responses.
\subsection p2p_sd_query Querying services of peers
Service discovery is implemented by processing pending queries as a
part of the device discovery phase. \ref p2p_sd_request() function is used
to schedule service discovery queries to a specific peer or to all
discovered peers. \ref p2p_sd_cancel_request() can be used to cancel a
scheduled query. Queries that are specific to a single peer will be
removed automatically after the response has been received.
After the service discovery queries have been queued, device discovery
is started with a call to \ref p2p_find(). The pending service discovery
queries are then sent whenever a peer is discovered during the find
operation. Responses to the queries will be reported with the
\ref p2p_config::sd_response() callback.
\subsection p2p_sd_response Replying to service discovery queries from peers
The received service discovery requests will be indicated with the
\ref p2p_config::sd_request() callback. The response to the query is sent
by calling \ref p2p_sd_response().
\subsection p2p_sd_indicator Service update indicator
P2P service discovery provides a mechanism to notify peers about
changes in available services. This works by incrementing Service
Update Indicator value whenever there is a change in the
services. This value is included in all SD request and response
frames. The value received from the peers will be included in the
\ref p2p_config::sd_request() and \ref p2p_config::sd_response() callbacks. The
value to be sent to the peers is incremented with a call to
\ref p2p_sd_service_update() whenever availability of the local services
changes.
\section p2p_go P2P group owner
This section describes how P2P module can be used for managing
per-group information in a group owner. The function calls are
described based on the P2P module API. The exact design for the glue
code outside the P2P module depends on the architecture used in the
system.
When a P2P group interface is created in group owner role, per-group
data is initialized with \ref p2p_group_init(). This call provides a
pointer to the per-device P2P module context and configures the
per-group operation. The configured \ref p2p_group_config::ie_update()
callback is used to set the initial P2P IE for Beacon and Probe
Response frames in the group owner. The AP mode implementation may use
this information to add IEs into the frames.
Once the group formation has been completed (or if it is skipped in
case of manual group setup), \ref p2p_group_notif_formation_done() is
called. This will allow the P2P module to update the P2P IE for
Beacon and Probe Response frames.
The SME/MLME code that managements IEEE 802.11 association processing
needs to inform P2P module whenever a P2P client associates or
disassociates with the group. This is done by calling
\ref p2p_group_notif_assoc() and \ref p2p_group_notif_disassoc(). The P2P module
manages a list of group members and updates the P2P Group Information
subelement in the P2P IE based on the information from the P2P
clients. The \ref p2p_group_config::ie_update() callback is used whenever
the P2P IE in Probe Response frames needs to be changed.
The SME/MLME code that takes care of replying to Probe Request frames
can use \ref p2p_group_match_dev_type() to check whether the Probe Request
frame request a reply only from groups that include a specific device
type in one of the clients or GO. A match will be reported if the
Probe Request does not request a specific device type, so this
function can be used to filter or received Probe Request frames and
only the ones that result in non-zero return value need to be replied.
When the P2P group interface for GO role is removed,
\ref p2p_group_deinit() is used to deinitialize the per-group P2P module
state.
\section p2p_ctrl_iface P2P control interface
wpa_supplicant \ref ctrl_iface_page "control interface" can be used
to manage P2P functionality from an external program (e.g., a GUI or a
system configuration manager). This interface can be used directly
through the control interface backend mechanism (e.g., local domain
sockets on Linux) or with help of wpa_cli (e.g., from a script).
The following P2P-related commands are available:
- \ref ctrl_iface_P2P_FIND P2P_FIND
- \ref ctrl_iface_P2P_STOP_FIND P2P_STOP_FIND
- \ref ctrl_iface_P2P_CONNECT P2P_CONNECT
- \ref ctrl_iface_P2P_LISTEN P2P_LISTEN
- \ref ctrl_iface_P2P_GROUP_REMOVE P2P_GROUP_REMOVE
- \ref ctrl_iface_P2P_GROUP_ADD P2P_GROUP_ADD

- \ref ctrl_iface_P2P_INVITE P2P_INVITE
The following P2P-related events are used:

\subsection p2p_wpa_gui GUI example (wpa_gui)
wpa_gui has an example implementation of a GUI that could be used to
manage P2P operations. The P2P related functionality is contained
mostly in wpa_supplicant/wpa_gui-qt4/peers.cpp and it shows how the
control interface commands and events can be used.
\subsection p2p_wpa_cli wpa_cli example
wpa_cli can be used to control wpa_supplicant in interactive
mode. The following sessions show examples of commands used for
device discovery and group formation. The lines starting with "> " are
commands from the user (followed by command result indication) and
lines starting with "<2>" are event messages from wpa_supplicant.

/**
\page porting Porting to different target boards and operating systems
wpa_supplicant was designed to be easily portable to different
hardware (board, CPU) and software (OS, drivers) targets. It is
already used with number of operating systems and numerous wireless
card models and drivers. The main wpa_supplicant repository includes
support for Linux, FreeBSD, and Windows. In addition, the code has been
ported to number of other operating systems like VxWorks, PalmOS,
Windows CE, and Windows Mobile. On the hardware
side, wpa_supplicant is used on various systems: desktops, laptops,
PDAs, and embedded devices with CPUs including x86, PowerPC,
arm/xscale, and MIPS. Both big and little endian configurations are
supported.
\section ansi_c_extra Extra functions on top of ANSI C
wpa_supplicant is mostly using ANSI C functions that are available on
most targets. However, couple of additional functions that are common
on modern UNIX systems are used. Number of these are listed with
prototypes in \ref common.h (the \verbatim #ifdef CONFIG_ANSI_C_EXTRA \endverbatim
block). These functions may need to be implemented or at least defined
as macros to native functions in the target OS or C library.
Many of the common ANSI C functions are used through a wrapper
definitions in \ref os.h to allow these to be replaced easily with a
platform specific version in case standard C libraries are not
available. In addition, \ref os.h defines couple of common platform
specific functions that are implemented in \ref os_unix.c for UNIX like
targets and in \ref os_win32.c for Win32 API. If the target platform does
not support either of these examples, a new os_*.c file may need to be
added.
Unless OS_NO_C_LIB_DEFINES is defined, the standard ANSI C and POSIX
functions are used by defining the os_*() wrappers to use them
directly in order to avoid extra cost in size and speed. If the target
platform needs different versions of the functions, \ref os.h can be
modified to define the suitable macros or alternatively,
OS_NO_C_LIB_DEFINES may be defined for the build and the wrapper
functions can then be implemented in a new os_*.c wrapper file.
\ref common.h defines number of helper macros for handling integers of
different size and byte order. Suitable version of these definitions
may need to be added for the target platform.
\section configuration_backend Configuration backend
wpa_supplicant implements a configuration interface that allows the
backend to be easily replaced in order to read configuration data from
a suitable source depending on the target platform. \ref config.c
implements the generic code that can be shared with all configuration
backends. Each backend is implemented in its own config_*.c file.
The included \ref config_file.c backend uses a text file for configuration
and \ref config_winreg.c uses Windows registry. These files can be used as
an example for a new configuration backend if the target platform uses
different mechanism for configuration parameters. In addition,
\ref config_none.c can be used as an empty starting point for building a
new configuration backend.
\section driver_iface_porting Driver interface
Unless the target OS and driver is already supported, most porting
projects have to implement a driver wrapper. This may be done by
adding a new driver interface module or modifying an existing module
(driver_*.c) if the new target is similar to one of them. \ref
driver_wrapper "Driver wrapper implementation" describes the details
of the driver interface and discusses the tasks involved in porting
this part of wpa_supplicant.
\section l2_packet_porting l2_packet (link layer access)
wpa_supplicant needs to have access to sending and receiving layer 2
(link layer) packets with two Ethertypes: EAP-over-LAN (EAPOL) 0x888e
and RSN pre-authentication 0x88c7. \ref l2_packet.h defines the interfaces
used for this in the core wpa_supplicant implementation.
If the target operating system supports a generic mechanism for link
layer access, that is likely the best mechanism for providing the
needed functionality for wpa_supplicant. Linux packet socket is an
example of such a generic mechanism. If this is not available, a
separate interface may need to be implemented to the network stack or
driver. This is usually an intermediate or protocol driver that is
operating between the device driver and the OS network stack. If such
a mechanism is not feasible, the interface can also be implemented
directly in the device driver.
The main wpa_supplicant repository includes l2_packet implementations
for Linux using packet sockets (\ref l2_packet_linux.c), more portable
version using libpcap/libdnet libraries (\ref l2_packet_pcap.c; this
supports WinPcap, too), and FreeBSD specific version of libpcap
interface (\ref l2_packet_freebsd.c).
If the target operating system is supported by libpcap (receiving) and
libdnet (sending), \ref l2_packet_pcap.c can likely be used with minimal or
no changes. If this is not a case or a proprietary interface for link
layer is required, a new l2_packet module may need to be
added. Alternatively, for hostapd,
struct \ref wpa_driver_ops::hapd_send_eapol() handler can
be used to override the l2_packet library if the link layer access is
integrated with the driver interface implementation.
\section eloop_porting Event loop
wpa_supplicant uses a single process/thread model and an event loop
to provide callbacks on events (registered timeout, received packet,
signal). eloop.h defines the event loop interface. \ref eloop.c is an
implementation of such an event loop using select() and sockets. This
is suitable for most UNIX/POSIX systems. When porting to other
operating systems, it may be necessary to replace that implementation
with OS specific mechanisms that provide similar functionality.
\section ctrl_iface_porting Control interface
wpa_supplicant uses a \ref ctrl_iface_page "control interface"
to allow external processed
to get status information and to control the operations. Currently,
this is implemented with socket based communication; both UNIX domain
sockets and UDP sockets are supported. If the target OS does not
support sockets, this interface will likely need to be modified to use
another mechanism like message queues. The control interface is
optional component, so it is also possible to run wpa_supplicant
without porting this part.
The wpa_supplicant side of the control interface is implemented in
\ref wpa_supplicant/ctrl_iface.c. Matching client side is implemented as a control
interface library in \ref wpa_ctrl.c.
\section entry_point Program entry point
wpa_supplicant defines a set of functions that can be used to
initialize main supplicant processing. Each operating system has a
mechanism for starting new processing or threads. This is usually a
function with a specific set of arguments and calling convention. This
function is responsible on initializing wpa_supplicant.
\ref wpa_supplicant/main.c includes an entry point for UNIX-like
operating system, i.e., main() function that uses command line arguments
for setting parameters for wpa_supplicant. When porting to other
operating systems, similar OS-specific entry point implementation is
needed. It can be implemented in a new file that is then linked with
wpa_supplicant instead of main.o. \ref wpa_supplicant/main.c is also a
good example on how the initialization process should be done.
The supplicant initialization functions are defined in
\ref wpa_supplicant_i.h. In most cases, the entry point function should
start by fetching configuration parameters. After this, a global
wpa_supplicant context is initialized with a call to
\ref wpa_supplicant_init(). After this, existing network interfaces can be
added with \ref wpa_supplicant_add_iface(). \ref wpa_supplicant_run() is then
used to start the main event loop. Once this returns at program
termination time, \ref wpa_supplicant_deinit() is used to release global
context data.
\ref wpa_supplicant_add_iface() and \ref wpa_supplicant_remove_iface() can be
used dynamically to add and remove interfaces based on when
wpa_supplicant processing is needed for them. This can be done, e.g.,
when hotplug network adapters are being inserted and ejected. It is
also possible to do this when a network interface is being
enabled/disabled if it is desirable that wpa_supplicant processing
for the interface is fully enabled/disabled at the same time.
\section simple_build Simple build example
One way to start a porting project is to begin with a very simple
build of wpa_supplicant with WPA-PSK support and once that is
building correctly, start adding features.
Following command can be used to build very simple version of
wpa_supplicant:
\verbatim
cc -o wpa_supplicant config.c eloop.c common.c md5.c rc4.c sha1.c \
config_none.c l2_packet_none.c tls_none.c wpa.c preauth.c \
aes_wrap.c wpa_supplicant.c events.c main_none.c drivers.c
\endverbatim
The end result is not really very useful since it uses empty functions
for configuration parsing and layer 2 packet access and does not
include a driver interface. However, this is a good starting point
since the build is complete in the sense that all functions are
present and this is easy to configure to a build system by just
including the listed C files.
Once this version can be build successfully, the end result can be
made functional by adding a proper program entry point (main*.c),
driver interface (driver_*.c and matching CONFIG_DRIVER_* define for
registration in \ref drivers.c), configuration parser/writer (config_*.c),
and layer 2 packet access implementation (l2_packet_*.c). After these
components have been added, the end result should be a working
WPA/WPA2-PSK enabled supplicant.
After the basic functionality has been verified to work, more features
can be added by linking in more files and defining C pre-processor
defines. Currently, the best source of information for what options
are available and which files needs to be included is in the Makefile
used for building the supplicant with make. Similar configuration will
be needed for build systems that either use different type of make
tool or a GUI-based project configuration.

\page testing_tools Testing and development tools

\ref unit_tests "Unit tests" |
\ref wpa_trace "Tracing code" ]
wpa_supplicant source tree includes number of testing and development
tools that make it easier to test the programs without having to setup
a full test setup with wireless cards. In addition, these tools can be
used to implement automatic tests suites.
\section eapol_test eapol_test - EAP peer and RADIUS client testing
eapol_test is a program that links together the same EAP peer
implementation that wpa_supplicant is using and the RADIUS
authentication client code from hostapd. In addition, it has minimal
glue code to combine these two components in similar ways to IEEE
802.1X/EAPOL Authenticator state machines. In other words, it
integrates IEEE 802.1X Authenticator (normally, an access point) and
IEEE 802.1X Supplicant (normally, a wireless client) together to
generate a single program that can be used to test EAP methods without
having to setup an access point and a wireless client.
The main uses for eapol_test are in interoperability testing of EAP
methods against RADIUS servers and in development testing for new EAP
methods. It can be easily used to automate EAP testing for
interoperability and regression since the program can be run from
shell scripts without require additional test components apart from a
RADIUS server. For example, the automated EAP tests described in
eap_testing.txt are implemented with eapol_test. Similarly, eapol_test
could be used to implement an automated regression test suite for a
RADIUS authentication server.
eapol_test uses the same build time configuration file, .config, as
wpa_supplicant. This file is used to select which EAP methods are
included in eapol_test. This program is not built with the default
Makefile target, so a separate make command needs to be used to
compile the tool:
\verbatim
make eapol_test
\endverbatim
The resulting eapol_test binary has following command like options:
\verbatim
usage:
eapol_test [-nWS] -c<conf> [-a<AS IP>] [-p<AS port>] [-s<AS secret>] \
[-r<count>] [-t<timeout>] [-C<Connect-Info>] \
[-M<client MAC address>]
eapol_test scard
eapol_test sim <PIN> <num triplets> [debug]
options:
-c<conf> = configuration file
-a<AS IP> = IP address of the authentication server, default 127.0.0.1
-p<AS port> = UDP port of the authentication server, default 1812
-s<AS secret> = shared secret with the authentication server, default 'radius'
-r<count> = number of re-authentications
-W = wait for a control interface monitor before starting
-S = save configuration after authentiation
-n = no MPPE keys expected
-t<timeout> = sets timeout in seconds (default: 30 s)
-C<Connect-Info> = RADIUS Connect-Info (default: CONNECT 11Mbps 802.11b)
-M<client MAC address> = Set own MAC address (Calling-Station-Id,
default: 02:00:00:00:00:01)
\endverbatim
As an example,
\verbatim
eapol_test -ctest.conf -a127.0.0.1 -p1812 -ssecret -r1
\endverbatim
tries to complete EAP authentication based on the network
configuration from test.conf against the RADIUS server running on the
local host. A re-authentication is triggered to test fast
re-authentication. The configuration file uses the same format for
network blocks as wpa_supplicant.
\section preauth_test preauth_test - WPA2 pre-authentication and EAP peer testing
preauth_test is similar to eapol_test in the sense that in combines
EAP peer implementation with something else, in this case, with WPA2
pre-authentication. This tool can be used to test pre-authentication
based on the code that wpa_supplicant is using. As such, it tests
both the wpa_supplicant implementation and the functionality of an
access point.
preauth_test is built with:
\verbatim
make preauth_test
\endverbatim
and it uses following command line arguments:
\verbatim
usage: preauth_test <conf> <target MAC address> <ifname>
\endverbatim
For example,
\verbatim
preauth_test test.conf 02:11:22:33:44:55 eth0
\endverbatim
would use network configuration from test.conf to try to complete
pre-authentication with AP using BSSID 02:11:22:33:44:55. The
pre-authentication packets would be sent using the eth0 interface.
\section unit_tests Unit tests
Number of the components (.c files) used in wpa_supplicant define
their own unit tests for automated validation of the basic
functionality. Most of the tests for cryptographic algorithms are
using standard test vectors to validate functionality. These tests can
be useful especially when verifying port to a new CPU target.
The test programs are collected in the tests subdirectory. All
automated unit tests can be run with
\verbatim
make run-tests
\endverbatim
This make target builds and runs each test and terminates with zero
exit code if all tests were completed successfully.
\section wpa_trace Tracing code for developer debuggin
wpa_supplicant and hostapd can be built with tracing code that will
track and analyze memory allocations and other resource registrations
and certain API uses. If incorrect use is detected, a backtrace of the
call location (and/or allocation location) is shown. This can also be
used to detect certain categories of memory leaks and report them
automatically when the program is terminated. The report will also
include information about forgotten eloop events.
The trace code can be enabled with CONFIG_WPA_TRACE=y build
option. More verbose backtrace information can be generated if libbfd
is available and the binaries are not stripped of symbol
information. This is enabled with CONFIG_WPA_TRACE_BFD=y.
For example, a memory leak (forgotten os_free() call) would show up
like this when the program is terminated:
\verbatim
MEMLEAK[0x82d200]: len 128
WPA_TRACE: memleak - START
[0]: ./wpa_supplicant(os_malloc+0x59) [0x41a5e9]
os_malloc() ../src/utils/os_unix.c:359
[1]: ./wpa_supplicant(os_zalloc+0x16) [0x41a676]
os_zalloc() ../src/utils/os_unix.c:418
[2]: ./wpa_supplicant(wpa_supplicant_init+0x38) [0x48b508]
wpa_supplicant_init() wpa_supplicant.c:2315
[3]: ./wpa_supplicant(main+0x2f3) [0x491073]
main() main.c:252
WPA_TRACE: memleak - END
MEMLEAK: total 128 bytes
\endverbatim
Another type of error that can be detected is freeing of memory area
that was registered for some use and is still be referenced:
\verbatim
WPA_TRACE: Freeing referenced memory - START
[2]: ./wpa_supplicant(os_free+0x5c) [0x41a53c]
os_free() ../src/utils/os_unix.c:411
[3]: ./wpa_supplicant(wpa_supplicant_remove_iface+0x30) [0x48b380]
wpa_supplicant_remove_iface() wpa_supplicant.c:2259
[4]: ./wpa_supplicant(wpa_supplicant_deinit+0x20) [0x48b3e0]
wpa_supplicant_deinit() wpa_supplicant.c:2430
[5]: ./wpa_supplicant(main+0x357) [0x4910d7]
main() main.c:276
WPA_TRACE: Freeing referenced memory - END
WPA_TRACE: Reference registration - START
[1]: ./wpa_supplicant [0x41c040]
eloop_trace_sock_add_ref() ../src/utils/eloop.c:94
[2]: ./wpa_supplicant(wpa_supplicant_ctrl_iface_deinit+0x17) [0x473247]
wpa_supplicant_ctrl_iface_deinit() ctrl_iface_unix.c:436
[3]: ./wpa_supplicant [0x48b21c]
wpa_supplicant_cleanup() wpa_supplicant.c:378
wpa_supplicant_deinit_iface() wpa_supplicant.c:2155
[4]: ./wpa_supplicant(wpa_supplicant_remove_iface+0x30) [0x48b380]
wpa_supplicant_remove_iface() wpa_supplicant.c:2259
[5]: ./wpa_supplicant(wpa_supplicant_deinit+0x20) [0x48b3e0]
wpa_supplicant_deinit() wpa_supplicant.c:2430
[6]: ./wpa_supplicant(main+0x357) [0x4910d7]
main() main.c:276
WPA_TRACE: Reference registration - END
Aborted
\endverbatim
This type of error results in showing backtraces for both the location
where the incorrect freeing happened and the location where the memory
area was marked referenced.

EAP peer/server library and example program
Copyright (c) 2007, Jouni Malinen <j@w1.fi>
This software may be distributed under the terms of the BSD license.
See the parent directory README for more details.
The interfaces of the EAP server/peer implementation are based on RFC
4137 (EAP State Machines). This RFC is coordinated with the state
machines defined in IEEE 802.1X-2004. hostapd and wpa_supplicant
include implementation of the IEEE 802.1X EAPOL state machines and the
interface between them and EAP. However, the EAP implementation can be
used with other protocols, too, by providing a compatible interface
which maps the EAPOL<->EAP variables to another protocol.
This directory contains an example showing how EAP peer and server
code from wpa_supplicant and hostapd can be used as a library. The
example program initializes both an EAP server and an EAP peer
entities and then runs through an EAP-PEAP/MSCHAPv2 authentication.
eap_example_peer.c shows the initialization and glue code needed to
control the EAP peer implementation. eap_example_server.c does the
same for EAP server. eap_example.c is an example that ties in both the
EAP server and client parts to allow an EAP authentication to be
shown.
In this example, the EAP messages are passed between the server and
the peer are passed by direct function calls within the same process.
In practice, server and peer functionalities would likely reside in
separate devices and the EAP messages would be transmitted between the
devices based on an external protocol. For example, in IEEE 802.11
uses IEEE 802.1X EAPOL state machines to control the transmission of
EAP messages and WiMax supports optional PMK EAP authentication
mechanism that transmits EAP messages as defined in IEEE 802.16e.
The EAP library links in number of helper functions from src/utils and
src/crypto directories. Most of these are suitable as-is, but it may
be desirable to replace the debug output code in src/utils/wpa_debug.c
by dropping this file from the library and re-implementing the
functions there in a way that better fits in with the main
application.

Hotspot 2.0 OSU server
======================
The information in this document is based on the assumption that Ubuntu
16.04 server (64-bit) distribution is used and the web server is
Apache2. Neither of these are requirements for the installation, but if
other combinations are used, the package names and configuration
parameters may need to be adjusted.
NOTE: This implementation and the example configuration here is meant
only for testing purposes in a lab environment. This design is not
secure to be installed in a publicly available Internet server without
considerable amount of modification and review for security issues.
Build dependencies
------------------
Ubuntu 16.04 server
- default installation
- upgraded to latest package versions
sudo apt-get update
sudo apt-get upgrade
Packages needed for running the service:
sudo apt-get install sqlite3
sudo apt-get install apache2
sudo apt-get install php-sqlite3 php-xml libapache2-mod-php
Additional packages needed for building the components:
sudo apt-get install build-essential
sudo apt-get install libsqlite3-dev
sudo apt-get install libssl-dev
sudo apt-get install libxml2-dev
Installation location
---------------------
Select a location for the installation root directory. The example here
assumes /home/user/hs20-server to be used, but this can be changed by
editing couple of files as indicated below.
sudo mkdir -p /home/user/hs20-server
sudo chown $USER /home/user/hs20-server
mkdir -p /home/user/hs20-server/spp
mkdir -p /home/user/hs20-server/AS

Start RADIUS authentication server
----------------------------------
cd /home/user/hs20-server/AS
./hostapd -B as-sql.conf
OSEN RADIUS server configuration notes
The OSEN RADIUS server config file should have the 'ocsp_stapling_response'
configuration in it. For example:
# hostapd-radius config for the radius used by the OSEN AP
interface=eth0#0
driver=none
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
eap_server=1
eap_user_file=/home/user/hs20-server/AS/hostapd-osen.eap_user
server_id=ben-ota-2-osen
radius_server_auth_port=1811
radius_server_clients=/home/user/hs20-server/AS/hostap.radius_clients
ca_cert=/home/user/hs20-server/ca/ca.pem
server_cert=/home/user/hs20-server/ca/server.pem
private_key=/home/user/hs20-server/ca/server.key
private_key_passwd=whatever
ocsp_stapling_response=/home/user/hs20-server/ca/ocsp-server-cache.der
The /home/user/hs20-server/AS/hostapd-osen.eap_user file should look
similar to this, and should coorelate with the osu_nai entry in
the non-OSEN VAP config file. For instance:
# cat hostapd-osen.eap_user
# For OSEN authentication (Hotspot 2.0 Release 2)
"osen@w1.fi" WFA-UNAUTH-TLS
# Run OCSP server:
cd /home/user/hs20-server/ca
./ocsp-responder.sh&
# Update cache (This should be run periodically)
./ocsp-update-cache.sh
Configure web server
--------------------
Edit /etc/apache2/sites-available/default-ssl
Add following block just before "SSL Engine Switch" line":
Alias /hs20/ "/home/user/hs20-server/www/"
<Directory "/home/user/hs20-server/www/">
Options Indexes MultiViews FollowSymLinks
AllowOverride None
Require all granted
SSLOptions +StdEnvVars
</Directory>
Update SSL configuration to use the OSU server certificate/key.
They keys and certs are called 'server.key' and 'server.pem' from
ca/setup.sh.
To support subscription remediation using client certificates, set
"SSLVerifyClient optional" and configure the trust root CA(s) for the
client certificates with SSLCACertificateFile.
Enable default-ssl site and restart Apache2:
sudo a2ensite default-ssl
sudo a2enmod ssl
sudo service apache2 restart
Management UI
-------------
The sample PHP scripts include a management UI for testing
purposes. That is available at https://<server>/hs20/users.php
AP configuration
----------------
APs can now be configured to use the OSU server as the RADIUS
authentication server. In addition, the OSU Provider List ANQP element
should be configured to use the SPP (SOAP+XML) option and with the
following Server URL:
https://<server>/hs20/spp.php/signup?realm=example.com

Example application using RADIUS client as a library
Copyright (c) 2007, Jouni Malinen <j@w1.fi>
This software may be distributed under the terms of the BSD license.
See the parent directory README for more details.
This directory contains an example showing how the RADIUS client
functionality from hostapd can be used as a library in another
program. The example program initializes the RADIUS client and send a
Access-Request using User-Name and User-Password attributes. A reply
from the RADIUS authentication server will be processed and it is used
as a trigger to terminate the example program.
The RADIUS library links in couple of helper functions from src/utils and
src/crypto directories. Most of these are suitable as-is, but it may
be desirable to replace the debug output code in src/utils/wpa_debug.c
by dropping this file from the library and re-implementing the
functions there in a way that better fits in with the main
application.
RADIUS client implementation takes care of receiving messages,
timeouts, and retransmissions of packets. Consequently, it requires
functionality for registering timeouts and received packet
notifications. This is implemented using the generic event loop
implementation (see src/utils/eloop.h).
The main application may either use the included event loop
implementation or alternatively, implement eloop_* wrapper functions
to use whatever event loop design is used in the main program. This
would involve removing src/utils/eloop.o from the library and
implementing following functions defines in src/utils/eloop.h:
eloop_register_timeout(), eloop_cancel_timeout(),
eloop_register_read_sock(), eloop_unregister_read_sock(), and
eloop_terminated().

hostap.git test tools
---------------------
The tests directory with its subdirectories contain number of tools used
for testing wpa_supplicant and hostapd implementations.
hwsim directory contains the test setup for full system testing of
wpa_supplicant and hostapd with a simulated radio (mac80211_hwsim). See
hwsim/READM and hwsim/vm/README for more details.
Build testing
-------------
wpa_supplicant and hostapd support number of build option
combinations. The test scripts in the build subdirectory can be used to
verify that various combinations do not break the builds. More
configuration examples can be added there
(build-{hostapd,wpa_supplicant}-*.config) to get them included in test
builds.
# Example
cd build
./run-build-tests.h
Fuzz testing
------------
Newer fuzz testing tools are under the fuzzing directory. See
fuzzing/README for more details on them. The following text describes
the older fuzz testing tools that are subject to removal once the same
newer tools have the same coverage available.
Number of the test tools here can be used for fuzz testing with tools
like American fuzzy lop (afl-fuzz) that are designed to modify an
external file for program input. ap-mgmt-fuzzer, eapol-fuzzer,
test-eapol, test-json, test-tls, and test-x509 are examples of such
tools that expose hostap.git module functionality with input from a file
specified on the command line.
Here are some examples of how fuzzing can be performed:

Cipher suite (CCMP, TKIP, GCMP, ..) and key management testing
==============================================================
wpa_supplicant and hostapd include number of extensions that allow
special test builds to be used for testing functionality related to
correct implementation of IEEE 802.11. These extensions allow behavior
to be modified and invalid operations to be performed to verify behavior
of other devices in unexpected situations. While most of the testing
extensions are focused on the fully automated testing framework with
mac80211_hwsim (see tests/hwsim subdirectory), many of these can be used
for over-the-air testing of the protocol as well.
Since some of the testing extensions can result in exposing key
information or allowing non-compliant behavior, these changes are
disabled in default wpa_supplicant and hostapd builds for production
purposes. Testing functionality can be enabled by adding
CONFIG_TESTING_OPTIONS=y into build configuration (hostapd/.config and
wpa_supplicant/.config).
Testing setup
-------------
These tests can be run as black-box testing without having to modify the
tested device at all or without knowing details of its
functionality. The test commands in wpa_supplicant/hostapd control
interfaces are used to perform unexpected operations and normal data
traffic is used to verify reaction of the tested device to such
operations.
In theory, the test functionality is available with most drivers
supported by wpa_supplicant/hostapd, but the most reliable results are
likely available through ath9k-based devices. If you are using something
else, it is strongly recommended that you'll run the first tests with
sniffer captures and verify that the test tools are behaving correctly.
wpa_supplicant is used to control a test device in station mode to test
an AP and hostapd is similarly used to control a test device in AP mode
to test a station.
Various data traffic generators could be used to test the behavior, but
this document focuses on using ping to test unicast traffic and arping
to test broadcast traffic. To keep things simple and to reduce
interference from unrelated traffic, the steps here assume static IPv4
addresses are used and IPv6 is disabled.
The tests here use WPA2-Personal for simplicity. WPA2-Enterprise and
other cipher suites can also be tested for more complete coverage.
Example hostapd.conf for the test tool in AP mode:
driver=nl80211
hw_mode=g
channel=1
ieee80211n=1
interface=wlan0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=adm
ssid=test-psk
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
wpa_passphrase=12345678
Example wpa_supplicant.conf for the test tool in station mode:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=adm
network={
ssid="test-psk"
key_mgmt=WPA-PSK
psk="12345678"
}
The examples in this document assume following IPv4 address
configuration:
Test tool (either AP or station mode): 192.168.1.1/24
Device under test: 192.168.1.2/24
Data traffic tests
------------------
ping is used to test whether unicast frames go through on the data
link. It should be noted that ping may need to use broadcast ARP at the
beginning if the other device is not yet in the ARP table, so working
broadcast and unicast connectivity may be needed to get this started.
Example:
$ ping -n -c 5 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.
64 bytes from 192.168.1.2: icmp_seq=1 ttl=64 time=43.7 ms
64 bytes from 192.168.1.2: icmp_seq=2 ttl=64 time=67.9 ms
64 bytes from 192.168.1.2: icmp_seq=3 ttl=64 time=900 ms
64 bytes from 192.168.1.2: icmp_seq=4 ttl=64 time=5.81 ms
64 bytes from 192.168.1.2: icmp_seq=5 ttl=64 time=135 ms
--- 192.168.1.2 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4004ms
rtt min/avg/max/mdev = 5.811/230.605/900.223/337.451 ms
This shows working unicast data connectivity.
$ ping -n -c 5 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.
--- 192.168.1.2 ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4033ms
This shows not working unicast data connectivity.
arping is used to test broadcast connectivity.
Example:
$ arping -b -I wlan0 192.168.1.2 -c 5
ARPING 192.168.1.2 from 192.168.1.1 wlan0
Unicast reply from 192.168.1.2 [<DUT MAC address>] 119.695ms
Unicast reply from 192.168.1.2 [<DUT MAC address>] 144.496ms
Unicast reply from 192.168.1.2 [<DUT MAC address>] 166.788ms
Unicast reply from 192.168.1.2 [<DUT MAC address>] 2.283ms
Unicast reply from 192.168.1.2 [<DUT MAC address>] 2.234ms
Sent 5 probes (5 broadcast(s))
Received 5 response(s)
This shows working broadcast data connectivity.
$ arping -b -I wlan0 192.168.1.2 -c 5
ARPING 192.168.1.2 from 192.168.1.1 wlan0
Sent 5 probes (5 broadcast(s))
Received 0 response(s)
This shows not working broadcast data connectivity.
If testing results do not look consistent, the testing state can be
cleared by disconnection and reconnecting the station (the test tool or
the DUT) to the network.
Sniffer and wlantest
--------------------
It is useful to get a wireless sniffer capture from the operating
channel of the AP to be able to confirm DUT behavior if any of the data
tests indicate reason to believe something is not working as expected.
wlantest (from the wlantest directory of hostap.git) can be used to
decrypt and analyze a sniffer capture. For example:
wlantest -r wlan0.pcap -n decrypted.pcap -p 12345678
The debug prints and comments in the generated file indicate where
unexpected behavior has been detected, e.g., when the test tool ends up
clearing its packet number to test replay protection. That can help in
checking whether the DUT actually replies to a frame that it was
supposed to drop due replay.
Testing replay protection on a station device
---------------------------------------------
Start hostapd and use hostapd_cli on the test device to control testing
operations. Connect the DUT to the network.
<3>AP-STA-CONNECTED <DUT MAC address>
This indicates that the connection was completed successfully.
Verify that broadcast and unicast traffic works correctly (if not,
something is wrong in the test setup and that needs to be resolved
before being able to run any tests).
Verify that unicast traffic works and issue the following command in
hostapd_cli:
> raw RESET_PN <DUT MAC address>
OK
Verify that unicast traffic does not work anymore. If it does, the DUT
does not implement replay protection correctly for unicast frames. Note
that unicast traffic can recover once the packet number from the test
device increases beyond the value used prior to that RESET_PN command.
Verify that broadcast traffic works and issue the following command in
hostapd_cli:
> raw RESET_PN ff:ff:ff:ff:ff:ff
OK
Verify that broadcast traffic does not work anymore. If it does, the DUT
does not implement replay protection correctly for broadcast
frames. Note that broadcast traffic can recover once the packet number
from the test device increases beyond the value used prior to that
RESET_PN command.
Testing replay protection on an AP device
-----------------------------------------
Start the AP (DUT) and start wpa_supplicant on the test device to
connect to the network. Use wpa_cli to control the test device.
<3>SME: Trying to authenticate with <DUT MAC address> (SSID='test-psk' freq=5240 MHz)
<3>CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD
<3>Trying to associate with <DUT MAC address> (SSID='test-psk' freq=5240 MHz)
<3>Associated with <DUT MAC address>
<3>WPA: Key negotiation completed with <DUT MAC address> [PTK=CCMP GTK=CCMP]
<3>CTRL-EVENT-CONNECTED - Connection to <DUT MAC address> completed [id=0 id_str=]
Verify that unicast traffic works and issue the following command in
wpa_cli:
> raw RESET_PN
OK
Verify that unicast traffic does not work anymore. If it does, the DUT
does not implement replay protection correctly. Note that unicast
traffic can recover once the packet number from the test device
increases beyond the value used prior to that RESET_PN command.
IEEE 802.11 protocol uses unicast frames in station-to-AP direction, so
there is no need to test AP replay protection behavior separately with
the broadcast IPv4 traffic (which would be converted to unicast frames
on the link layer).
Testing GTK reinstallation protection on a station device (group handshake)
---------------------------------------------------------------------------
Use the procedure describe above for testing replay protection, but with
the following hostapd_cli commands:
Test broadcast connectivity; should work
> raw RESEND_GROUP_M1 <DUT MAC address>
OK
> raw RESET_PN ff:ff:ff:ff:ff:ff
OK
Test broadcast connectivity; should not work; if it does, the device
does not implement protection for delayed retransmission of Group Key
Message 1/2.
Testing GTK reinstallation protection on a station device (4-way handshake)
---------------------------------------------------------------------------
Use the procedure described above for testing replay protection for
broadcast traffic, but with the following hostapd_cli commands:
Test broadcast connectivity; should work
> raw RESEND_M3 <DUT MAC address>
OK
> raw RESET_PN ff:ff:ff:ff:ff:ff
OK
Test broadcast connectivity; should not work; if it does, the device
does not implement protection for delayed retransmission of 4-way
handshake EAPOL-Key Message 3/4.
Variant 1: Include extra Message 1/4
Otherwise same as above, but replace RESEND_M3 command with:
> raw RESEND_M1 <DUT MAC address>
OK
> raw RESEND_M3 <DUT MAC address>
OK
Variant 2: Include two extra Message 1/4
Otherwise same as above, but replace RESEND_M3 command with:

OK
> raw RESEND_M1 <DUT MAC address>

Testing TK reinstallation protection on a station device (4-way handshake)
--------------------------------------------------------------------------
Use the procedure described above for testing replay protection for
unicast traffic, but with the following hostapd_cli commands:
Test unicast connectivity; should work
> raw RESEND_M3 <DUT MAC address>
OK
> raw RESET_PN <DUT MAC address>
OK
Test unicast connectivity; should not work; if it does, the device
does not implement protection for delayed retransmission of 4-way
handshake EAPOL-Key Message 3/4.
Variant 1: Include extra Message 1/4
Otherwise same as above, but replace RESEND_M3 command with:
> raw RESEND_M1 <DUT MAC address>
OK
> raw RESEND_M3 <DUT MAC address>
OK
Variant 2: Include two extra Message 1/4
Otherwise same as above, but replace RESEND_M3 command with:
> raw RESEND_M1 <DUT MAC address> change-anonce
OK
> raw RESEND_M1 <DUT MAC address>
OK
> raw RESEND_M3 <DUT MAC address>
OK
Testing ANonce generation on an AP device
-----------------------------------------
Start the AP (DUT) and start wpa_supplicant on the test device to
connect to the network. Use wpa_cli to control the test device.
<3>SME: Trying to authenticate with <DUT MAC address> (SSID='test-psk' freq=5240 MHz)
<3>CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD
<3>Trying to associate with <DUT MAC address> (SSID='test-psk' freq=5240 MHz)
<3>Associated with <DUT MAC address>
<3>WPA: Key negotiation completed with <DUT MAC address> [PTK=CCMP GTK=CCMP]
<3>CTRL-EVENT-CONNECTED - Connection to <DUT MAC address> completed [id=0 id_str=]
Show the ANonce from the first 4-way handshake, request PTK rekeying,
and show the ANonce from the second 4-way handshake:
> GET anonce
df8c61d1f1f7aca9f1739dd888199547f4af2b8b07f8bf15b45ea271da0072b2
> raw KEY_REQUEST 0 1
OK
> GET anonce
d8ddcb716f28abfdf1352a05d51e7a70f58802122e99d13c730c3c0f09594aac
If the ANonce values are same, the AP did not update the ANonce for
rekeying (it should have as shown in the example above).
Testing FT Reassociation Request frame retransmission on an AP device
---------------------------------------------------------------------
This test case requires a sniffer to be used and manually analyzed.
Enable FT on the DUT AP (likely two AP devices needed), connect test
tool to the AP using FT protocol (e.g., connect to another AP first and
then use the "ROAM <BSSID>" command), and do the following steps:
- verify unicast traffic from the AP to test station (either ping from
the AP or from a device behind the AP); this needs to work
- wpa_cli "raw RESEND_ASSOC"
- verify unicast traffic from the AP to test station (either ping from
the AP or from a device behind the AP); this is likely to fail, but
the real analysis is done based on the sniffer capture
In the sniffer capture, find the last Reassociation Request frame from
the test station (this is more or less identical to the previous one and
the only one that should not have Authentication frame exchange before
it). Look at the last used PN in a unicast Data frame from the AP to the
test station before the last Reassociation Request frame and the PN in
the following unicast Data frame after the last Reassociation Request
frame. If the PN goes down (e.g., is reset to 1), this would be a sign
of a likely security vulnerability. The AP's TK configuration should be
verified (i.e., whether it is configuring the same TK again and then
allowing it to be used with reused PN values).

hostap.git fuzz testing
-----------------------
These tools can be used for fuzz testing of various components used
within wpa_supplicant and hostapd. Each directory contains a fuzzing
tool that focuses on one input handler. Each tool can be compiled either
to work with the libFuzzer or as a separate tool that reads the input
from a file specified on the command line, e.g., for American fuzzy lop
(afl-fuzz). Example test corpus is included in */corpus directory.
Example fuzzing with libFuzzer
cd @TOOL@
make clean
make LIBFUZZER=y
./@TOOL@ corpus
Example fuzzing with afl-fuzz
cd @TOOL@
make clean
CC=afl-gcc make
afl-fuzz -i corpus -o findings -- $PWD/@TOOL@ @@
