ChangeLog for wpa_supplicant
|
|
|
|
2008-11-01 - v0.6.5
|
|
* added support for SHA-256 as X.509 certificate digest when using the
|
|
internal X.509/TLSv1 implementation
|
|
* updated management frame protection to use IEEE 802.11w/D6.0
|
|
* added support for using SHA256-based stronger key derivation for WPA2
|
|
(IEEE 802.11w)
|
|
* fixed FT (IEEE 802.11r) authentication after a failed association to
|
|
use correct FTIE
|
|
* added support for configuring Phase 2 (inner/tunneled) authentication
|
|
method with wpa_gui-qt4
|
|
|
|
2008-08-10 - v0.6.4
|
|
* added support for EAP Sequences in EAP-FAST Phase 2
|
|
* added support for using TNC with EAP-FAST
|
|
* added driver_ps3 for the PS3 Linux wireless driver
|
|
* added support for optional cryptobinding with PEAPv0
|
|
* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
|
|
allow fallback to full handshake if server rejects PAC-Opaque
|
|
* added fragmentation support for EAP-TNC
|
|
* added support for parsing PKCS #8 formatted private keys into the
|
|
internal TLS implementation (both PKCS #1 RSA key and PKCS #8
|
|
encapsulated RSA key can now be used)
|
|
* added option of using faster, but larger, routines in the internal
|
|
LibTomMath (for internal TLS implementation) to speed up DH and RSA
|
|
calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
|
|
* fixed race condition between disassociation event and group key
|
|
handshake to avoid getting stuck in incorrect state [Bug 261]
|
|
* fixed opportunistic key caching (proactive_key_caching)
|
|
|
|
2008-02-22 - v0.6.3
|
|
* removed 'nai' and 'eappsk' network configuration variables that were
|
|
previously used for configuring user identity and key for EAP-PSK,
|
|
EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
|
|
replacement for 'nai' (if old configuration used a separate
|
|
'identity' value, that would now be configured as
|
|
'anonymous_identity'). 'password' field is now used as the
|
|
replacement for 'eappsk' (it can also be set using hexstring to
|
|
present random binary data)
|
|
* removed '-w' command line parameter (wait for interface to be added,
|
|
if needed); cleaner way of handling this functionality is to use an
|
|
external mechanism (e.g., hotplug scripts) that start wpa_supplicant
|
|
when an interface is added
|
|
* updated FT support to use the latest draft, IEEE 802.11r/D9.0
|
|
* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
|
|
indicating when new scan results become available
|
|
* added new ctrl_iface command, BSS, to allow scan results to be
|
|
fetched without hitting the message size limits (this command
|
|
can be used to iterate through the scan results one BSS at the time)
|
|
* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
|
|
attributes in EAP-SIM Start/Response when using fast reauthentication
|
|
* fixed EAPOL not to end up in infinite loop when processing dynamic
|
|
WEP keys with IEEE 802.1X
|
|
* fixed problems in getting NDIS events from WMI on Windows 2000
|
|
|
|
2008-01-01 - v0.6.2
|
|
* added support for Makefile builds to include debug-log-to-a-file
|
|
functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
|
|
* fixed EAP-SIM and EAP-AKA message parser to validate attribute
|
|
lengths properly to avoid potential crash caused by invalid messages
|
|
* added data structure for storing allocated buffers (struct wpabuf);
|
|
this does not affect wpa_supplicant usage, but many of the APIs
|
|
changed and various interfaces (e.g., EAP) is not compatible with old
|
|
versions
|
|
* added support for protecting EAP-AKA/Identity messages with
|
|
AT_CHECKCODE (optional feature in RFC 4187)
|
|
* added support for protected result indication with AT_RESULT_IND for
|
|
EAP-SIM and EAP-AKA (phase1="result_ind=1")
|
|
* added driver_wext workaround for race condition between scanning and
|
|
association with drivers that take very long time to scan all
|
|
channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
|
|
using a longer hardcoded timeout for the scan if the driver supports
|
|
notifications for scan completion (SIOCGIWSCAN event); this helps,
|
|
e.g., in cases where wpa_supplicant and madwifi driver ended up in
|
|
loop where the driver did not even try to associate
|
|
* stop EAPOL timer tick when no timers are in use in order to reduce
|
|
power consumption (no need to wake up the process once per second)
|
|
[Bug 237]
|
|
* added support for privilege separation (run only minimal part of
|
|
wpa_supplicant functionality as root and rest as unprivileged,
|
|
non-root process); see 'Privilege separation' in README for details;
|
|
this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
|
|
in .config
|
|
* changed scan results data structure to include all information
|
|
elements to make it easier to support new IEs; old get_scan_result()
|
|
driver_ops is still supported for backwards compatibility (results
|
|
are converted internally to the new format), but all drivers should
|
|
start using the new get_scan_results2() to make them more likely to
|
|
work with new features
|
|
* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
|
|
application, i.e., it does not require Qt3Support anymore; Windows
|
|
binary of wpa_gui.exe is now from this directory and only requires
|
|
QtCore4.dll and QtGui4.dll libraries
|
|
* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
|
|
available as a separate package to make wpa_gui installation easier:
|
|
http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
|
|
* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
|
|
only shared key/password authentication is supported in this version
|
|
|
|
2007-11-24 - v0.6.1
|
|
* added support for configuring password as NtPasswordHash
|
|
(16-byte MD4 hash of password) in hash:<32 hex digits> format
|
|
* added support for fallback from abbreviated TLS handshake to
|
|
full handshake when using EAP-FAST (e.g., due to an expired
|
|
PAC-Opaque)
|
|
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
|
draft (draft-ietf-emu-eap-gpsk-07.txt)
|
|
* added support for drivers that take care of RSN 4-way handshake
|
|
internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
|
|
WPA_ALG_PMK in set_key)
|
|
* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
|
|
.config); this version supports only ap_scan=2 mode and allow the
|
|
driver to take care of the 4-way handshake
|
|
* fixed a buffer overflow in parsing TSF from scan results when using
|
|
driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
|
|
[Bug 232]
|
|
* updated FT support to use the latest draft, IEEE 802.11r/D8.0
|
|
* fixed an integer overflow issue in the ASN.1 parser used by the
|
|
(experimental) internal TLS implementation to avoid a potential
|
|
buffer read overflow
|
|
* fixed a race condition with -W option (wait for a control interface
|
|
monitor before starting) that could have caused the first messages to
|
|
be lost
|
|
* added support for processing TNCC-TNCS-Messages to report
|
|
recommendation (allow/none/isolate) when using TNC [Bug 243]
|
|
|
|
2007-05-28 - v0.6.0
|
|
* added network configuration parameter 'frequency' for setting
|
|
initial channel for IBSS (adhoc) networks
|
|
* added experimental IEEE 802.11r/D6.0 support
|
|
* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
|
|
* updated EAP-PSK to use the IANA-allocated EAP type 47
|
|
* fixed EAP-PAX key derivation
|
|
* fixed EAP-PSK bit ordering of the Flags field
|
|
* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
|
|
tunnelled identity request (previously, the identifier from the outer
|
|
method was used, not the tunnelled identifier which could be
|
|
different)
|
|
* added support for fragmentation of outer TLS packets during Phase 2
|
|
of EAP-PEAP/TTLS/FAST
|
|
* fixed EAP-TTLS AVP parser processing for too short AVP lengths
|
|
* added support for EAP-FAST authentication with inner methods that
|
|
generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
|
|
for PAC provisioning)
|
|
* added support for authenticated EAP-FAST provisioning
|
|
* added support for configuring maximum number of EAP-FAST PACs to
|
|
store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
|
|
* added support for storing EAP-FAST PACs in binary format
|
|
(fast_pac_format=binary in phase1 string)
|
|
* fixed dbus ctrl_iface to validate message interface before
|
|
dispatching to avoid a possible segfault [Bug 190]
|
|
* fixed PeerKey key derivation to use the correct PRF label
|
|
* updated Windows binary build to link against OpenSSL 0.9.8d and
|
|
added support for EAP-FAST
|
|
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
|
draft (draft-ietf-emu-eap-gpsk-04.txt)
|
|
* fixed EAP-AKA Notification processing to allow Notification to be
|
|
processed after AKA Challenge response has been sent
|
|
* updated to use IEEE 802.11w/D2.0 for management frame protection
|
|
(still experimental)
|
|
* fixed EAP-TTLS implementation not to crash on use of freed memory
|
|
if TLS library initialization fails
|
|
* added support for EAP-TNC (Trusted Network Connect)
|
|
(this version implements the EAP-TNC method and EAP-TTLS changes
|
|
needed to run two methods in sequence (IF-T) and the IF-IMC and
|
|
IF-TNCCS interfaces from TNCC)
|
|
|
|
2006-11-24 - v0.5.6
|
|
* added experimental, integrated TLSv1 client implementation with the
|
|
needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
|
|
setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
|
|
.config); this can be useful, e.g., if the target system does not
|
|
have a suitable TLS library and a minimal code size is required
|
|
(total size of this internal TLS/crypto code is bit under 50 kB on
|
|
x86 and the crypto code is shared by rest of the supplicant so some
|
|
of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
|
|
* removed STAKey handshake since PeerKey handshake has replaced it in
|
|
IEEE 802.11ma and there are no known deployments of STAKey
|
|
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
|
|
draft (draft-ietf-emu-eap-gpsk-01.txt)
|
|
* added preliminary implementation of IEEE 802.11w/D1.0 (management
|
|
frame protection)
|
|
(Note: this requires driver support to work properly.)
|
|
(Note2: IEEE 802.11w is an unapproved draft and subject to change.)
|
|
* fixed Windows named pipes ctrl_iface to not stop listening for
|
|
commands if client program opens a named pipe and closes it
|
|
immediately without sending a command
|
|
* fixed USIM PIN status determination for the case that PIN is not
|
|
needed (this allows EAP-AKA to be used with USIM cards that do not
|
|
use PIN)
|
|
* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
|
|
be used with cards that do not support file selection based on
|
|
partial AID
|
|
* added support for matching the subjectAltName of the authentication
|
|
server certificate against multiple name components (e.g.,
|
|
altsubject_match="DNS:server.example.com;DNS:server2.example.com")
|
|
* fixed EAP-SIM/AKA key derivation for re-authentication case (only
|
|
affects IEEE 802.1X with dynamic WEP keys)
|
|
* changed ctrl_iface network configuration 'get' operations to not
|
|
return password/key material; if these fields are requested, "*"
|
|
will be returned if the password/key is set, but the value of the
|
|
parameter is not exposed
|
|
|
|
2006-08-27 - v0.5.5
|
|
* added support for building Windows version with UNICODE defined
|
|
(wide-char functions)
|
|
* driver_ndis: fixed static WEP configuration to avoid race condition
|
|
issues with some NDIS drivers between association and setting WEP
|
|
keys
|
|
* driver_ndis: added validation for IELength value in scan results to
|
|
avoid crashes when using buggy NDIS drivers [Bug 165]
|
|
* fixed Release|Win32 target in the Visual Studio project files
|
|
(previously, only Debug|Win32 target was set properly)
|
|
* changed control interface API call wpa_ctrl_pending() to allow it to
|
|
return -1 on error (e.g., connection lost); control interface clients
|
|
will need to make sure that they verify that the value is indeed >0
|
|
when determining whether there are pending messages
|
|
* added an alternative control interface backend for Windows targets:
|
|
Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
|
|
control interface mechanism for Windows builds (previously, UDP to
|
|
localhost was used)
|
|
* changed ctrl_interface configuration for UNIX domain sockets:
|
|
- deprecated ctrl_interface_group variable (it may be removed in
|
|
future versions)
|
|
- allow both directory and group be configured with ctrl_interface
|
|
in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
|
|
- ctrl_interface=/var/run/wpa_supplicant is still supported for the
|
|
case when group is not changed
|
|
* added support for controlling more than one interface per process in
|
|
Windows version
|
|
* added a workaround for a case where the AP is using unknown address
|
|
(e.g., MAC address of the wired interface) as the source address for
|
|
EAPOL-Key frames; previously, that source address was used as the
|
|
destination for EAPOL-Key frames and in key derivation; now, BSSID is
|
|
used even if the source address does not match with it
|
|
(this resolves an interoperability issue with Thomson SpeedTouch 580)
|
|
* added a workaround for UDP-based control interface (which was used in
|
|
Windows builds before this release) to prevent packets with forged
|
|
addresses from being accepted as local control requests
|
|
* removed ndis_events.cpp and possibility of using external
|
|
ndis_events.exe; C version (ndis_events.c) is fully functional and
|
|
there is no desire to maintain two separate versions of this
|
|
implementation
|
|
* ndis_events: Changed NDIS event notification design to use WMI to
|
|
learn the adapter description through Win32_PnPEntity class; this
|
|
should fix some cases where the adapter name was not recognized
|
|
correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
|
|
USB) [Bug 113]
|
|
* fixed selection of the first network in ap_scan=2 mode; previously,
|
|
wpa_supplicant could get stuck in SCANNING state when only the first
|
|
network for enabled (e.g., after 'wpa_cli select_network 0')
|
|
* winsvc: added support for configuring ctrl_interface parameters in
|
|
registry (ctrl_interface string value in
|
|
HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
|
|
required to enable control interface (previously, this was hardcoded
|
|
to be enabled)
|
|
* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
|
|
* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
|
|
|
|
2006-06-20 - v0.5.4
|
|
* fixed build with CONFIG_STAKEY=y [Bug 143]
|
|
* added support for doing MLME (IEEE 802.11 management frame
|
|
processing) in wpa_supplicant when using Devicescape IEEE 802.11
|
|
stack (wireless-dev.git tree)
|
|
* added a new network block configuration option, fragment_size, to
|
|
configure the maximum EAP fragment size
|
|
* driver_ndis: Disable WZC automatically for the selected interface to
|
|
avoid conflicts with two programs trying to control the radio; WZC
|
|
will be re-enabled (if it was enabled originally) when wpa_supplicant
|
|
is terminated
|
|
* added an experimental TLSv1 client implementation
|
|
(CONFIG_TLS=internal) that can be used instead of an external TLS
|
|
library, e.g., to reduce total size requirement on systems that do
|
|
not include any TLS library by default (this is not yet complete;
|
|
basic functionality is there, but certificate validation is not yet
|
|
included)
|
|
* added PeerKey handshake implementation for IEEE 802.11e
|
|
direct link setup (DLS) to replace STAKey handshake
|
|
* fixed WPA PSK update through ctrl_iface for the case where the old
|
|
PSK was derived from an ASCII passphrase and the new PSK is set as
|
|
a raw PSK (hex string)
|
|
* added new configuration option for identifying which network block
|
|
was used (id_str in wpa_supplicant.conf; included on
|
|
WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
|
|
variable in wpa_cli action scripts; in addition WPA_ID variable is
|
|
set to the current unique identifier that wpa_supplicant assigned
|
|
automatically for the network and that can be used with
|
|
GET_NETWORK/SET_NETWORK ctrl_iface commands)
|
|
* wpa_cli action script is now called only when the connect/disconnect
|
|
status changes or when associating with a different network
|
|
* fixed configuration parser not to remove CCMP from group cipher list
|
|
if WPA-None (adhoc) is used (pairwise=NONE in that case)
|
|
* fixed integrated NDIS events processing not to hang the process due
|
|
to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
|
|
* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
|
|
draft-clancy-emu-eap-shared-secret-00.txt)
|
|
* added Microsoft Visual Studio 2005 solution and project files for
|
|
build wpa_supplicant for Windows (see vs2005 subdirectory)
|
|
* eloop_win: fixed unregistration of Windows events
|
|
* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
|
|
at the end of RSN pre-authentication and added unregistration of
|
|
a Windows event to avoid getting eloop_win stuck with an invalid
|
|
handle
|
|
* driver_ndis: added support for selecting AP based on BSSID
|
|
* added new environmental variable for wpa_cli action scripts:
|
|
WPA_CTRL_DIR is the current control interface directory
|
|
* driver_ndis: added support for using NDISUIO instead of WinPcap for
|
|
OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
|
|
l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
|
|
wpa_supplicant without requiring WinPcap; note that using NDISUIO
|
|
requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
|
|
only one application to open the device
|
|
* changed NDIS driver naming to only include device GUID, e.g.,
|
|
{7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
|
|
specific \Device\NPF_ prefix before the GUID; the prefix is still
|
|
allowed for backwards compatibility, but it is not required anymore
|
|
when specifying the interface
|
|
* driver_ndis: re-initialize driver interface is the adapter is removed
|
|
and re-inserted [Bug 159]
|
|
* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
|
|
big endian hosts [Bug 146]
|
|
|
|
2006-04-27 - v0.5.3
|
|
* fixed EAP-GTC response to include correct user identity when run as
|
|
phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
|
|
* driver_ndis: Fixed encryption mode configuration for unencrypted
|
|
networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
|
|
refused to associate with open networks) [Bug 106]
|
|
* driver_ndis: use BSSID OID polling to detect when IBSS network is
|
|
formed even when ndis_events code is included since some NDIS drivers
|
|
do not generate media connect events in IBSS mode
|
|
* config_winreg: allow global ctrl_interface parameter to be configured
|
|
in Windows registry
|
|
* config_winreg: added support for saving configuration data into
|
|
Windows registry
|
|
* added support for controlling network device operational state
|
|
(dormant/up) for Linux 2.6.17 to improve DHCP processing (see
|
|
http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
|
|
that can use this information)
|
|
* driver_wext: added support for WE-21 change to SSID configuration
|
|
* driver_wext: fixed privacy configuration for static WEP keys mode
|
|
[Bug 140]
|
|
* added an optional driver_ops callback for MLME-SETPROTECTION.request
|
|
primitive
|
|
* added support for EAP-SAKE (no EAP method number allocated yet, so
|
|
this is using the same experimental type 255 as EAP-PSK)
|
|
* added support for dynamically loading EAP methods (.so files) instead
|
|
of requiring them to be statically linked in; this is disabled by
|
|
default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
|
|
on how to use this)
|
|
|
|
2006-03-19 - v0.5.2
|
|
* do not try to use USIM APDUs when initializing PC/SC for SIM card
|
|
access for a network that has not enabled EAP-AKA
|
|
* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
|
|
v0.5.1 due to the new support for expanded EAP types)
|
|
* added support for generating EAP Expanded Nak
|
|
* try to fetch scan results once before requesting new scan when
|
|
starting up in ap_scan=1 mode (this can speed up initial association
|
|
a lot with, e.g., madwifi-ng driver)
|
|
* added support for receiving EAPOL frames from a Linux bridge
|
|
interface (-bbr0 on command line)
|
|
* fixed EAPOL re-authentication for sessions that used PMKSA caching
|
|
* changed EAP method registration to use a dynamic list of methods
|
|
instead of a static list generated at build time
|
|
* fixed PMKSA cache deinitialization not to use freed memory when
|
|
removing PMKSA entries
|
|
* fixed a memory leak in EAP-TTLS re-authentication
|
|
* reject WPA/WPA2 message 3/4 if it does not include any valid
|
|
WPA/RSN IE
|
|
* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
|
|
if the driver does not support SIOCSIWAUTH
|
|
|
|
2006-01-29 - v0.5.1
|
|
* driver_test: added better support for multiple APs and STAs by using
|
|
a directory with sockets that include MAC address for each device in
|
|
the name (driver_param=test_dir=/tmp/test)
|
|
* added support for EAP expanded type (vendor specific EAP methods)
|
|
* added AP_SCAN command into ctrl_iface so that ap_scan configuration
|
|
option can be changed if needed
|
|
* wpa_cli/wpa_gui: skip non-socket files in control directory when
|
|
using UNIX domain sockets; this avoids selecting an incorrect
|
|
interface (e.g., a PID file could be in this directory, even though
|
|
use of this directory for something else than socket files is not
|
|
recommended)
|
|
* fixed TLS library deinitialization after RSN pre-authentication not
|
|
to disable TLS library for normal authentication
|
|
* driver_wext: Remove null-termination from SSID length if the driver
|
|
used it; some Linux drivers do this and they were causing problems in
|
|
wpa_supplicant not finding matching configuration block. This change
|
|
would break a case where the SSID actually ends in '\0', but that is
|
|
not likely to happen in real use.
|
|
* fixed PMKSA cache processing not to trigger deauthentication if the
|
|
current PMKSA cache entry is replaced with a valid new entry
|
|
* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
|
|
EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
|
|
ap_scan=2)
|
|
|
|
2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
|
|
* added experimental STAKey handshake implementation for IEEE 802.11e
|
|
direct link setup (DLS); note: this is disabled by default in both
|
|
build and runtime configuration (can be enabled with CONFIG_STAKEY=y
|
|
and stakey=1)
|
|
* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
|
|
decrypt AT_ENCR_DATA attributes correctly
|
|
* fixed EAP-AKA to allow resynchronization within the same session
|
|
* made code closer to ANSI C89 standard to make it easier to port to
|
|
other C libraries and compilers
|
|
* started moving operating system or C library specific functions into
|
|
wrapper functions defined in os.h and implemented in os_*.c to make
|
|
code more portable
|
|
* wpa_supplicant can now be built with Microsoft Visual C++
|
|
(e.g., with the freely available Toolkit 2003 version or Visual
|
|
C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
|
|
example makefile for nmake
|
|
* added support for using Windows registry for command line parameters
|
|
(CONFIG_MAIN=main_winsvc) and configuration data
|
|
(CONFIG_BACKEND=winreg); see win_example.reg for an example registry
|
|
contents; this version can be run both as a Windows service and as a
|
|
normal application; 'wpasvc.exe app' to start as applicant,
|
|
'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
|
|
'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
|
|
unregister a service
|
|
* made it possible to link ndis_events.exe functionality into
|
|
wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
|
|
* added better support for multiple control interface backends
|
|
(CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
|
|
* fixed PC/SC code to use correct length for GSM AUTH command buffer
|
|
and to not use pioRecvPci with SCardTransmit() calls; these were not
|
|
causing visible problems with pcsc-lite, but Windows Winscard.dll
|
|
refused the previously used parameters; this fixes EAP-SIM and
|
|
EAP-AKA authentication using SIM/USIM card under Windows
|
|
* added new event loop implementation for Windows using
|
|
WaitForMultipleObject() instead of select() in order to allow waiting
|
|
for non-socket objects; this can be selected with
|
|
CONFIG_ELOOP=eloop_win in .config
|
|
* added support for selecting l2_packet implementation in .config
|
|
(CONFIG_L2_PACKET; following options are available now: linux, pcap,
|
|
winpcap, freebsd, none)
|
|
* added new l2_packet implementation for WinPcap
|
|
(CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
|
|
reduce latency in EAPOL receive processing from about 100 ms to about
|
|
3 ms
|
|
* added support for EAP-FAST key derivation using other ciphers than
|
|
RC4-128-SHA for authentication and AES128-SHA for provisioning
|
|
* added support for configuring CA certificate as DER file and as a
|
|
configuration blob
|
|
* fixed private key configuration as configuration blob and added
|
|
support for using PKCS#12 as a blob
|
|
* tls_gnutls: added support for using PKCS#12 files; added support for
|
|
session resumption
|
|
* added support for loading trusted CA certificates from Windows
|
|
certificate store: ca_cert="cert_store://<name>", where <name> is
|
|
likely CA (Intermediate CA certificates) or ROOT (root certificates)
|
|
* added C version of ndis_events.cpp and made it possible to build this
|
|
with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
|
|
easily on cross-compilation builds
|
|
* added wpasvc.exe into Windows binary release; this is an alternative
|
|
version of wpa_supplicant.exe with configuration backend using
|
|
Windows registry and with the entry point designed to run as a
|
|
Windows service
|
|
* integrated ndis_events.exe functionality into wpa_supplicant.exe and
|
|
wpasvc.exe and removed this additional tool from the Windows binary
|
|
release since it is not needed anymore
|
|
* load winscard.dll functions dynamically when building with MinGW
|
|
since MinGW does not yet include winscard library
|
|
|
|
2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
|
|
* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
|
|
and WinPcap to receive frames sent to PAE group address
|
|
* disable EAP state machine when IEEE 802.1X authentication is not used
|
|
in order to get rid of bogus "EAP failed" messages
|
|
* fixed OpenSSL error reporting to go through all pending errors to
|
|
avoid confusing reports of old errors being reported at later point
|
|
during handshake
|
|
* fixed configuration file updating to not write empty variables
|
|
(e.g., proto or key_mgmt) that the file parser would not accept
|
|
* fixed ADD_NETWORK ctrl_iface command to use the same default values
|
|
for variables as empty network definitions read from config file
|
|
would get
|
|
* fixed EAP state machine to not discard EAP-Failure messages in many
|
|
cases (e.g., during TLS handshake)
|
|
* fixed a infinite loop in private key reading if the configured file
|
|
cannot be parsed successfully
|
|
* driver_madwifi: added support for madwifi-ng
|
|
* wpa_gui: do not display password/PSK field contents
|
|
* wpa_gui: added CA certificate configuration
|
|
* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
|
|
* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
|
|
the new AP is using different WPA/RSN IE
|
|
* use longer timeout for IEEE 802.11 association to avoid problems with
|
|
drivers that may take more than five second to associate
|
|
|
|
2005-10-27 - v0.4.6
|
|
* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
|
|
RSN IE, but WPA IE would match with wpa_supplicant configuration
|
|
* added support for named configuration blobs in order to avoid having
|
|
to use file system for external files (e.g., certificates);
|
|
variables can be set to "blob://<blob name>" instead of file path to
|
|
use a named blob; supported fields: pac_file, client_cert,
|
|
private_key
|
|
* fixed RSN pre-authentication (it was broken in the clean up of WPA
|
|
state machine interface in v0.4.5)
|
|
* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
|
|
sure the driver configures broadcast decryption correctly
|
|
* added ca_path (and ca_path2) configuration variables that can be used
|
|
to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
|
|
system-wide trusted CA list
|
|
* added support for starting wpa_supplicant without a configuration
|
|
file (-C argument must be used to set ctrl_interface parameter for
|
|
this case; in addition, -p argument can be used to provide
|
|
driver_param; these new arguments can also be used with a
|
|
configuration to override the values from the configuration)
|
|
* added global control interface that can be optionally used for adding
|
|
and removing network interfaces dynamically (-g command line argument
|
|
for both wpa_supplicant and wpa_cli) without having to restart
|
|
wpa_supplicant process
|
|
* wpa_gui:
|
|
- try to save configuration whenever something is modified
|
|
- added WEP key configuration
|
|
- added possibility to edit the current network configuration
|
|
* driver_ndis: fixed driver polling not to increase frequency on each
|
|
received EAPOL frame due to incorrectly cancelled timeout
|
|
* added simple configuration file examples (in examples subdirectory)
|
|
* fixed driver_wext.c to filter wireless events based on ifindex to
|
|
avoid interfaces receiving events from other interfaces
|
|
* delay sending initial EAPOL-Start couple of seconds to speed up
|
|
authentication for the most common case of Authenticator starting
|
|
EAP authentication immediately after association
|
|
|
|
2005-09-25 - v0.4.5
|
|
* added a workaround for clearing keys with ndiswrapper to allow
|
|
roaming from WPA enabled AP to plaintext one
|
|
* added docbook documentation (doc/docbook) that can be used to
|
|
generate, e.g., man pages
|
|
* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
|
|
PF_PACKET in order to prepare for network devices that do not use
|
|
Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
|
|
* use receipt of EAPOL-Key frame as a lower layer success indication
|
|
for EAP state machine to allow recovery from dropped EAP-Success
|
|
frame
|
|
* cleaned up internal EAPOL frame processing by not including link
|
|
layer (Ethernet) header during WPA and EAPOL/EAP processing; this
|
|
header is added only when transmitted the frame; this makes it easier
|
|
to use wpa_supplicant on link layers that use different header than
|
|
Ethernet
|
|
* updated EAP-PSK to use draft 9 by default since this can now be
|
|
tested with hostapd; removed support for draft 3, including
|
|
server_nai configuration option from network blocks
|
|
* driver_wired: add PAE address to the multicast address list in order
|
|
to be able to receive EAPOL frames with drivers that do not include
|
|
these multicast addresses by default
|
|
* driver_wext: add support for WE-19
|
|
* added support for multiple configuration backends (CONFIG_BACKEND
|
|
option); currently, only 'file' is supported (i.e., the format used
|
|
in wpa_supplicant.conf)
|
|
* added support for updating configuration ('wpa_cli save_config');
|
|
this is disabled by default and can be enabled with global
|
|
update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
|
|
and wpa_gui to store the configuration changes in a permanent store
|
|
* added GET_NETWORK ctrl_iface command
|
|
(e.g., 'wpa_cli get_network 0 ssid')
|
|
|
|
2005-08-21 - v0.4.4
|
|
* replaced OpenSSL patch for EAP-FAST support
|
|
(openssl-tls-extensions.patch) with a more generic and correct
|
|
patch (the new patch is not compatible with the previous one, so the
|
|
OpenSSL library will need to be patched with the new patch in order
|
|
to be able to build wpa_supplicant with EAP-FAST support)
|
|
* added support for using Windows certificate store (through CryptoAPI)
|
|
for client certificate and private key operations (EAP-TLS)
|
|
(see wpa_supplicant.conf for more information on how to configure
|
|
this with private_key)
|
|
* ported wpa_gui to Windows
|
|
* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
|
|
built with the open source version of the Qt4 for Windows
|
|
* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
|
|
with drivers that do not support WPA
|
|
* ndis_events: fixed Windows 2000 support
|
|
* added support for enabling/disabling networks from the list of all
|
|
configured networks ('wpa_cli enable_network <network id>' and
|
|
'wpa_cli disable_network <network id>')
|
|
* added support for adding and removing network from the current
|
|
configuration ('wpa_cli add_network' and 'wpa_cli remove_network
|
|
<network id>'); added networks are disabled by default and they can
|
|
be enabled with enable_network command once the configuration is done
|
|
for the new network; note: configuration file is not yet updated, so
|
|
these new networks are lost when wpa_supplicant is restarted
|
|
* added support for setting network configuration parameters through
|
|
the control interface, for example:
|
|
wpa_cli set_network 0 ssid "\"my network\""
|
|
* fixed parsing of strings that include both " and # within double
|
|
quoted area (e.g., "start"#end")
|
|
* added EAP workaround for PEAP session resumption: allow outer,
|
|
i.e., not tunneled, EAP-Success to terminate session since; this can
|
|
be disabled with eap_workaround=0
|
|
(this was allowed for PEAPv1 before, but now it is also allowed for
|
|
PEAPv0 since at least one RADIUS authentication server seems to be
|
|
doing this for PEAPv0, too)
|
|
* wpa_gui: added preliminary support for adding new networks to the
|
|
wpa_supplicant configuration (double click on the scan results to
|
|
open network configuration)
|
|
|
|
2005-06-26 - v0.4.3
|
|
* removed interface for external EAPOL/EAP supplicant (e.g.,
|
|
Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
|
|
anymore and is unlikely to be used by anyone
|
|
* driver_ndis: fixed WinPcap 3.0 support
|
|
* fixed build with CONFIG_DNET_PCAP=y on Linux
|
|
* l2_packet: moved different implementations into separate files
|
|
(l2_packet_*.c)
|
|
|
|
2005-06-12 - v0.4.2
|
|
* driver_ipw: updated driver structures to match with ipw2200-1.0.4
|
|
(note: ipw2100-1.1.0 is likely to require an update to work with
|
|
this)
|
|
* added support for using ap_scan=2 mode with multiple network blocks;
|
|
wpa_supplicant will go through the networks one by one until the
|
|
driver reports a successful association; this uses the same order for
|
|
networks as scan_ssid=1 scans, i.e., the priority field is ignored
|
|
and the network block order in the file is used instead
|
|
* fixed a potential issue in RSN pre-authentication ending up using
|
|
freed memory if pre-authentication times out
|
|
* added support for matching alternative subject name extensions of the
|
|
authentication server certificate; new configuration variables
|
|
altsubject_match and altsubject_match2
|
|
* driver_ndis: added support for IEEE 802.1X authentication with wired
|
|
NDIS drivers
|
|
* added support for querying private key password (EAP-TLS) through the
|
|
control interface (wpa_cli/wpa_gui) if one is not included in the
|
|
configuration file
|
|
* driver_broadcom: fixed couple of memory leaks in scan result
|
|
processing
|
|
* EAP-PAX is now registered as EAP type 46
|
|
* fixed EAP-PAX MAC calculation
|
|
* fixed EAP-PAX CK and ICK key derivation
|
|
* added support for using password with EAP-PAX (as an alternative to
|
|
entering key with eappsk); SHA-1 hash of the password will be used as
|
|
the key in this case
|
|
* added support for arbitrary driver interface parameters through the
|
|
configuration file with a new driver_param field; this adds a new
|
|
driver_ops function set_param()
|
|
* added possibility to override l2_packet module with driver interface
|
|
API (new send_eapol handler); this can be used to implement driver
|
|
specific TX/RX functions for EAPOL frames
|
|
* fixed ctrl_interface_group processing for the case where gid is
|
|
entered as a number, not group name
|
|
* driver_test: added support for testing hostapd with wpa_supplicant
|
|
by using test driver interface without any kernel drivers or network
|
|
cards
|
|
|
|
2005-05-22 - v0.4.1
|
|
* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
|
|
packets to be encrypted; this was apparently broken by the changed
|
|
ioctl order in v0.4.0
|
|
* driver_madwifi: added preliminary support for compiling against 'BSD'
|
|
branch of madwifi CVS tree
|
|
* added support for EAP-MSCHAPv2 password retries within the same EAP
|
|
authentication session
|
|
* added support for password changes with EAP-MSCHAPv2 (used when the
|
|
password has expired)
|
|
* added support for reading additional certificates from PKCS#12 files
|
|
and adding them to the certificate chain
|
|
* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
|
|
were used
|
|
* fixed a possible double free in EAP-TTLS fast-reauthentication when
|
|
identity or password is entered through control interface
|
|
* display EAP Notification messages to user through control interface
|
|
with "CTRL-EVENT-EAP-NOTIFICATION" prefix
|
|
* added GUI version of wpa_cli, wpa_gui; this is not build
|
|
automatically with 'make'; use 'make wpa_gui' to build (this requires
|
|
Qt development tools)
|
|
* added 'disconnect' command to control interface for setting
|
|
wpa_supplicant in state where it will not associate before
|
|
'reassociate' command has been used
|
|
* added support for selecting a network from the list of all configured
|
|
networks ('wpa_cli select_network <network id>'; this disabled all
|
|
other networks; to re-enable, 'wpa_cli select_network any')
|
|
* added support for getting scan results through control interface
|
|
* added EAP workaround for PEAPv1 session resumption: allow outer,
|
|
i.e., not tunneled, EAP-Success to terminate session since; this can
|
|
be disabled with eap_workaround=0
|
|
|
|
2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
|
|
* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
|
|
used to reduce the size of the wpa_supplicant considerably if
|
|
debugging code is not needed
|
|
* fixed EAPOL-Key validation to drop packets with invalid Key Data
|
|
Length; such frames could have crashed wpa_supplicant due to buffer
|
|
overflow
|
|
* added support for wired authentication (IEEE 802.1X on wired
|
|
Ethernet); driver interface 'wired'
|
|
* obsoleted set_wpa() handler in the driver interface API (it can be
|
|
replaced by moving enable/disable functionality into init()/deinit())
|
|
(calls to set_wpa() are still present for backwards compatibility,
|
|
but they may be removed in the future)
|
|
* driver_madwifi: fixed association in plaintext mode
|
|
* modified the EAP workaround that accepts EAP-Success with incorrect
|
|
Identifier to be even less strict about verification in order to
|
|
interoperate with some authentication servers
|
|
* added support for sending TLS alerts
|
|
* added support for 'any' SSID wildcard; if ssid is not configured or
|
|
is set to an empty string, any SSID will be accepted for non-WPA AP
|
|
* added support for asking PIN (for SIM) from frontends (e.g.,
|
|
wpa_cli); if a PIN is needed, but not included in the configuration
|
|
file, a control interface request is sent and EAP processing is
|
|
delayed until the PIN is available
|
|
* added support for using external devices (e.g., a smartcard) for
|
|
private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
|
|
new wpa_supplicant.conf variables:
|
|
- global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
|
|
- network: engine, engine_id, key_id
|
|
* added experimental support for EAP-PAX
|
|
* added monitor mode for wpa_cli (-a<path to a program to run>) that
|
|
allows external commands (e.g., shell scripts) to be run based on
|
|
wpa_supplicant events, e.g., when authentication has been completed
|
|
and data connection is ready; other related wpa_cli arguments:
|
|
-B (run in background), -P (write PID file); wpa_supplicant has a new
|
|
command line argument (-W) that can be used to make it wait until a
|
|
control interface command is received in order to avoid missing
|
|
events
|
|
* added support for opportunistic WPA2 PMKSA key caching (disabled by
|
|
default, can be enabled with proactive_key_caching=1)
|
|
* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
|
|
Authenticator rejects PMKSA caching attempt and the driver is not
|
|
using assoc_info events
|
|
* added -P<pid file> argument for wpa_supplicant to write the current
|
|
process id into a file
|
|
|
|
2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
|
|
* added new phase1 option parameter, include_tls_length=1, to force
|
|
wpa_supplicant to add TLS Message Length field to all TLS messages
|
|
even if the packet is not fragmented; this may be needed with some
|
|
authentication servers
|
|
* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
|
|
using drivers that take care of AP selection (e.g., when using
|
|
ap_scan=2)
|
|
* fixed reprocessing of pending request after ctrl_iface requests for
|
|
identity/password/otp
|
|
* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
|
|
EAP-PEAP and EAP-TTLS
|
|
* all drivers using driver_wext: set interface up and select Managed
|
|
mode when starting wpa_supplicant; set interface down when exiting
|
|
* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
|
|
ipw2100 and ipw2200; please note that this also changed the
|
|
configuration variable in .config to CONFIG_DRIVER_IPW
|
|
|
|
2005-01-24 - v0.3.6
|
|
* fixed a busy loop introduced in v0.3.5 for scan result processing
|
|
when no matching AP is found
|
|
|
|
2005-01-23 - v0.3.5
|
|
* added a workaround for an interoperability issue with a Cisco AP
|
|
when using WPA2-PSK
|
|
* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
|
|
WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
|
|
retransmission of dropped frames)
|
|
* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
|
|
(e.g., segfault when processing EAPOL-Key frames)
|
|
* fixed EAP workaround and fast reauthentication configuration for
|
|
RSN pre-authentication; previously these were disabled and
|
|
pre-authentication would fail if the used authentication server
|
|
requires EAP workarounds
|
|
* added support for blacklisting APs that fail or timeout
|
|
authentication in ap_scan=1 mode so that all APs are tried in cases
|
|
where the ones with strongest signal level are failing authentication
|
|
* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
|
|
authentication attempt
|
|
* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
|
|
in the previous authentication (previously, only Phase 1 success was
|
|
verified)
|
|
|
|
2005-01-09 - v0.3.4
|
|
* added preliminary support for IBSS (ad-hoc) mode configuration
|
|
(mode=1 in network block); this included a new key_mgmt mode
|
|
WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
|
|
key management; see wpa_supplicant.conf for more details and an
|
|
example on how to configure this (note: this is currently implemented
|
|
only for driver_hostapd.c, but the changes should be trivial to add
|
|
in associate() handler for other drivers, too (assuming the driver
|
|
supports WPA-None)
|
|
* added preliminary port for native Windows (i.e., no cygwin) using
|
|
mingw
|
|
|
|
2005-01-02 - v0.3.3
|
|
* added optional support for GNU Readline and History Libraries for
|
|
wpa_cli (CONFIG_READLINE)
|
|
* cleaned up EAP state machine <-> method interface and number of
|
|
small problems with error case processing not terminating on
|
|
EAP-Failure but waiting for timeout
|
|
* added couple of workarounds for interoperability issues with a
|
|
Cisco AP when using WPA2
|
|
* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
|
|
Note: This requires a patch for openssl to add support for TLS
|
|
extensions and number of workarounds for operations without
|
|
certificates. Proof of concept type of experimental patch is
|
|
included in openssl-tls-extensions.patch.
|
|
|
|
2004-12-19 - v0.3.2
|
|
* fixed private key loading for cases where passphrase is not set
|
|
* fixed Windows/cygwin L2 packet handler freeing; previous version
|
|
could cause a segfault when RSN pre-authentication was completed
|
|
* added support for PMKSA caching with drivers that generate RSN IEs
|
|
(e.g., NDIS); currently, this is only implemented in driver_ndis.c,
|
|
but similar code can be easily added to driver_ndiswrapper.c once
|
|
ndiswrapper gets full support for RSN PMKSA caching
|
|
* improved recovery from PMKID mismatches by requesting full EAP
|
|
authentication in case of failed PMKSA caching attempt
|
|
* driver_ndis: added support for NDIS NdisMIncidateStatus() events
|
|
(this requires that ndis_events is ran while wpa_supplicant is
|
|
running)
|
|
* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
|
|
* added support for driver interfaces to replace the interface name
|
|
based on driver/OS specific mapping, e.g., in case of driver_ndis,
|
|
this allows the beginning of the adapter description to be used as
|
|
the interface name
|
|
* added support for CR+LF (Windows-style) line ends in configuration
|
|
file
|
|
* driver_ndis: enable radio before starting scanning, disable radio
|
|
when exiting
|
|
* modified association event handler to set portEnabled = FALSE before
|
|
clearing port Valid in order to reset EAP state machine and avoid
|
|
problems with new authentication getting ignored because of state
|
|
machines ending up in AUTHENTICATED/SUCCESS state based on old
|
|
information
|
|
* added support for driver events to add PMKID candidates in order to
|
|
allow drivers to give priority to most likely roaming candidates
|
|
* driver_hostap: moved PrivacyInvoked configuration to associate()
|
|
function so that this will not be set for plaintext connections
|
|
* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
|
|
interface can distinguish plaintext and IEEE 802.1X (no WPA)
|
|
authentication
|
|
* fixed static WEP key configuration to use broadcast/default type for
|
|
all keys (previously, the default TX key was configured as pairwise/
|
|
unicast key)
|
|
* driver_ndis: added legacy WPA capability detection for non-WPA2
|
|
drivers
|
|
* added support for setting static WEP keys for IEEE 802.1X without
|
|
dynamic WEP keying (eapol_flags=0)
|
|
|
|
2004-12-12 - v0.3.1
|
|
* added support for reading PKCS#12 (PFX) files (as a replacement for
|
|
PEM/DER) to get certificate and private key (CONFIG_PKCS12)
|
|
* fixed compilation with CONFIG_PCSC=y
|
|
* added new ap_scan mode, ap_scan=2, for drivers that take care of
|
|
association, but need to be configured with security policy and SSID,
|
|
e.g., ndiswrapper and NDIS driver; this mode should allow such
|
|
drivers to work with hidden SSIDs and optimized roaming; when
|
|
ap_scan=2 is used, only the first network block in the configuration
|
|
file is used and this configuration should have explicit security
|
|
policy (i.e., only one option in the lists) for key_mgmt, pairwise,
|
|
group, proto variables
|
|
* added experimental port of wpa_supplicant for Windows
|
|
- driver_ndis.c driver interface (NDIS OIDs)
|
|
- currently, this requires cygwin and WinPcap
|
|
- small utility, win_if_list, can be used to get interface name
|
|
* control interface can now be removed at build time; add
|
|
CONFIG_CTRL_IFACE=y to .config to maintain old functionality
|
|
* optional Xsupplicant interface can now be removed at build time;
|
|
(CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
|
|
* added auth_alg to driver interface associate() parameters to make it
|
|
easier for drivers to configure authentication algorithm as part of
|
|
the association
|
|
|
|
2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
|
|
* driver_broadcom: added new driver interface for Broadcom wl.o driver
|
|
(a generic driver for Broadcom IEEE 802.11a/g cards)
|
|
* wpa_cli: fixed parsing of -p <path> command line argument
|
|
* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
|
|
ACK, not tunneled EAP-Success (of which only the first byte was
|
|
actually send due to a bug in previous code); this seems to
|
|
interoperate with most RADIUS servers that implements PEAPv1
|
|
* PEAPv1: added support for terminating PEAP authentication on tunneled
|
|
EAP-Success message; this can be configured by adding
|
|
peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
|
|
(some RADIUS servers require this whereas others require a tunneled
|
|
reply
|
|
* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
|
|
the old label for key derivation; previously, the default was 1,
|
|
but it looks like most existing PEAPv1 implementations use the old
|
|
label which is thus more suitable default option
|
|
* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
|
|
* fixed parsing of wep_tx_keyidx
|
|
* added support for configuring list of allowed Phase 2 EAP types
|
|
(for both EAP-PEAP and EAP-TTLS) instead of only one type
|
|
* added support for configuring IEEE 802.11 authentication algorithm
|
|
(auth_alg; mainly for using Shared Key authentication with static
|
|
WEP keys)
|
|
* added support for EAP-AKA (with UMTS SIM)
|
|
* fixed couple of errors in PCSC handling that could have caused
|
|
random-looking errors for EAP-SIM
|
|
* added support for EAP-SIM pseudonyms and fast re-authentication
|
|
* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
|
|
session resumption)
|
|
* added support for EAP-SIM with two challanges
|
|
(phase1="sim_min_num_chal=3" can be used to require three challenges)
|
|
* added support for configuring DH/DSA parameters for an ephemeral DH
|
|
key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
|
|
dh_file and dh_file2 (phase 2); this adds support for using DSA keys
|
|
and optional DH key exchange to achieve forward secracy with RSA keys
|
|
* added support for matching subject of the authentication server
|
|
certificate with a substring when using EAP-TLS/PEAP/TTLS; new
|
|
configuration variables subject_match and subject_match2
|
|
* changed SSID configuration in driver_wext.c (used by many driver
|
|
interfaces) to use ssid_len+1 as the length for SSID since some Linux
|
|
drivers expect this
|
|
* fixed couple of unaligned reads in scan result parsing to fix WPA
|
|
connection on some platforms (e.g., ARM)
|
|
* added driver interface for Intel ipw2100 driver
|
|
* added support for LEAP with WPA
|
|
* added support for larger scan results report (old limit was 4 kB of
|
|
data, i.e., about 35 or so APs) when using Linux wireless extensions
|
|
v17 or newer
|
|
* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
|
|
only if there is a PMKSA cache entry for the current AP
|
|
* fixed error handling for case where reading of scan results fails:
|
|
must schedule a new scan or wpa_supplicant will remain waiting
|
|
forever
|
|
* changed debug output to remove shared password/key material by
|
|
default; all key information can be included with -K command line
|
|
argument to match the previous behavior
|
|
* added support for timestamping debug log messages (disabled by
|
|
default, can be enabled with -t command line argument)
|
|
* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
|
|
if keys are not configured to be used; this fixes IEEE 802.1X mode
|
|
with drivers that use this information to configure whether Privacy
|
|
bit can be in Beacon frames (e.g., ndiswrapper)
|
|
* avoid clearing driver keys if no keys have been configured since last
|
|
key clear request; this seems to improve reliability of group key
|
|
handshake for ndiswrapper & NDIS driver which seems to be suffering
|
|
of some kind of timing issue when the keys are cleared again after
|
|
association
|
|
* changed driver interface API:
|
|
- WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
|
|
version is being used (now, this is set to 2; previously, it was
|
|
not defined)
|
|
- pass pointer to private data structure to all calls
|
|
- the new API is not backwards compatible; all in-tree driver
|
|
interfaces has been converted to the new API
|
|
* added support for controlling multiple interfaces (radios) per
|
|
wpa_supplicant process; each interface needs to be listed on the
|
|
command line (-c, -i, -D arguments) with -N as a separator
|
|
(-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
|
|
* added a workaround for EAP servers that incorrectly use same Id for
|
|
sequential EAP packets
|
|
* changed libpcap/libdnet configuration to use .config variable,
|
|
CONFIG_DNET_PCAP, instead of requiring Makefile modification
|
|
* improved downgrade attack detection in IE verification of msg 3/4:
|
|
verify both WPA and RSN IEs, if present, not only the selected one;
|
|
reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
|
|
Probe Response frame, and RSN is enabled in wpa_supplicant
|
|
configuration
|
|
* fixed WPA msg 3/4 processing to allow Key Data field contain other
|
|
IEs than just one WPA IE
|
|
* added support for FreeBSD and driver interface for the BSD net80211
|
|
layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
|
|
required kernel mods have not yet been committed
|
|
* made EAP workarounds configurable; enabled by default, can be
|
|
disabled with network block option eap_workaround=0
|
|
|
|
2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
|
|
* resolved couple of interoperability issues with EAP-PEAPv1 and
|
|
Phase 2 (inner EAP) fragment reassembly
|
|
* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
|
|
AP is using non-zero key index for the unicast key and key index zero
|
|
for the broadcast key
|
|
* driver_hostap: fixed IEEE 802.1X WEP key updates and
|
|
re-authentication by allowing unencrypted EAPOL frames when not using
|
|
WPA
|
|
* added a new driver interface, 'wext', which uses only standard,
|
|
driver independent functionality in Linux wireless extensions;
|
|
currently, this can be used only for non-WPA IEEE 802.1X mode, but
|
|
eventually, this is to be extended to support full WPA/WPA2 once
|
|
Linux wireless extensions get support for this
|
|
* added support for mode in which the driver is responsible for AP
|
|
scanning and selection; this is disabled by default and can be
|
|
enabled with global ap_scan=0 variable in wpa_supplicant.conf;
|
|
this mode can be used, e.g., with generic 'wext' driver interface to
|
|
use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
|
|
supporting wireless extensions.
|
|
* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
|
|
operation with an AP that does not include SSID in the Beacon frames)
|
|
* added support for new EAP authentication methods:
|
|
EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
|
|
* added support for asking one-time-passwords from frontends (e.g.,
|
|
wpa_cli); this 'otp' command works otherwise like 'password' command,
|
|
but the password is used only once and the frontend will be asked for
|
|
a new password whenever a request from authenticator requires a
|
|
password; this can be used with both EAP-OTP and EAP-GTC
|
|
* changed wpa_cli to automatically re-establish connection so that it
|
|
does not need to be re-started when wpa_supplicant is terminated and
|
|
started again
|
|
* improved user data (identity/password/otp) requests through
|
|
frontends: process pending EAPOL packets after getting new
|
|
information so that full authentication does not need to be
|
|
restarted; in addition, send pending requests again whenever a new
|
|
frontend is attached
|
|
* changed control frontends to use a new directory for socket files to
|
|
make it easier for wpa_cli to automatically select between interfaces
|
|
and to provide access control for the control interface;
|
|
wpa_supplicant.conf: ctrl_interface is now a path
|
|
(/var/run/wpa_supplicant is the recommended path) and
|
|
ctrl_interface_group can be used to select which group gets access to
|
|
the control interface;
|
|
wpa_cli: by default, try to connect to the first interface available
|
|
in /var/run/wpa_supplicant; this path can be overriden with -p option
|
|
and an interface can be selected with -i option (i.e., in most common
|
|
cases, wpa_cli does not need to get any arguments)
|
|
* added support for LEAP
|
|
* added driver interface for Linux ndiswrapper
|
|
* added priority option for network blocks in the configuration file;
|
|
this allows networks to be grouped based on priority (the scan
|
|
results are searched for matches with network blocks in this order)
|
|
|
|
2004-06-20 - v0.2.3
|
|
* sort scan results to improve AP selection
|
|
* fixed control interface socket removal for some error cases
|
|
* improved scan requesting and authentication timeout
|
|
* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
|
|
TLS processing
|
|
* PEAP version can now be forced with phase1="peapver=<ver>"
|
|
(mostly for testing; by default, the highest version supported by
|
|
both the Supplicant and Authentication Server is selected
|
|
automatically)
|
|
* added support for madwifi driver (Atheros ar521x)
|
|
* added a workaround for cases where AP sets Install Tx/Rx bit for
|
|
WPA Group Key messages when pairwise keys are used (without this,
|
|
the Group Key would be used for Tx and the AP would drop frames
|
|
from the station)
|
|
* added GSM SIM/USIM interface for GSM authentication algorithm for
|
|
EAP-SIM; this requires pcsc-lite
|
|
* added support for ATMEL AT76C5XXx driver
|
|
* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
|
|
does not include key data in the EAPOL-Key frame (i.e., part of
|
|
EAP keying material is used as data encryption key)
|
|
* added support for using plaintext and static WEP networks
|
|
(key_mgmt=NONE)
|
|
|
|
2004-05-31 - v0.2.2
|
|
* added support for new EAP authentication methods:
|
|
EAP-TTLS/EAP-MD5-Challenge
|
|
EAP-TTLS/EAP-GTC
|
|
EAP-TTLS/EAP-MSCHAPv2
|
|
EAP-TTLS/EAP-TLS
|
|
EAP-TTLS/MSCHAPv2
|
|
EAP-TTLS/MSCHAP
|
|
EAP-TTLS/PAP
|
|
EAP-TTLS/CHAP
|
|
EAP-PEAP/TLS
|
|
EAP-PEAP/GTC
|
|
EAP-PEAP/MD5-Challenge
|
|
EAP-GTC
|
|
EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
|
|
* added support for anonymous identity (to be used when identity is
|
|
sent in plaintext; real identity will be used within TLS protected
|
|
tunnel (e.g., with EAP-TTLS)
|
|
* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
|
|
* added support for requesting identity and password information using
|
|
control interface; in other words, the password for EAP-PEAP or
|
|
EAP-TTLS does not need to be included in the configuration file since
|
|
a frontand (e.g., wpa_cli) can ask it from the user
|
|
* improved RSN pre-authentication to use a candidate list and process
|
|
all candidates from each scan; not only one per scan
|
|
* fixed RSN IE and WPA IE capabilities field parsing
|
|
* ignore Tx bit in GTK IE when Pairwise keys are used
|
|
* avoid making new scan requests during IEEE 802.1X negotiation
|
|
* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
|
|
with TLS support (this replaces the included implementation with
|
|
library code to save about 8 kB since the library code is needed
|
|
anyway for TLS)
|
|
* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
|
|
(i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
|
|
|
|
2004-05-06 - v0.2.1
|
|
* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
|
|
Supplicant
|
|
- EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
|
|
- EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
|
|
- EAP-MD5 (cannot be used with WPA-RADIUS)
|
|
[draft-ietf-eap-rfc2284bis-09.txt]
|
|
- EAP-TLS [RFC 2716]
|
|
- EAP-MSCHAPv2 (currently used only with EAP-PEAP)
|
|
- EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
|
|
[draft-kamath-pppext-eap-mschapv2-00.txt]
|
|
(PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
|
|
default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
|
|
- new configuration file options: eap, identity, password, ca_cert,
|
|
client_cert, privatekey, private_key_passwd
|
|
- Xsupplicant is not required anymore, but it can be used by
|
|
disabling the internal IEEE 802.1X Supplicant with -e command line
|
|
option
|
|
- this code is not included in the default build; Makefile need to
|
|
be edited for this (uncomment lines for selected functionality)
|
|
- EAP-TLS and EAP-PEAP require openssl libraries
|
|
* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
|
|
* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
|
|
(i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
|
|
EAPOL-Key frames instead of WPA key handshakes)
|
|
* added support for IEEE 802.11i/RSN (WPA2)
|
|
- improved PTK Key Handshake
|
|
- PMKSA caching, pre-authentication
|
|
* fixed wpa_supplicant to ignore possible extra data after WPA
|
|
EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
|
|
TPTK' error from message 3 of 4-Way Handshake in case the AP
|
|
includes extra data after the EAPOL-Key)
|
|
* added interface for external programs (frontends) to control
|
|
wpa_supplicant
|
|
- CLI example (wpa_cli) with interactive mode and command line
|
|
mode
|
|
- replaced SIGUSR1 status/statistics with the new control interface
|
|
* made some feature compile time configurable
|
|
- .config file for make
|
|
- driver interfaces (hostap, hermes, ..)
|
|
- EAPOL/EAP functions
|
|
|
|
2004-02-15 - v0.2.0
|
|
* Initial version of wpa_supplicant
|
