-
-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.
