IEEE 802.11r KDF uses key length in the derivation and as such, the PTK length must be specified correctly. The previous version was deriving using 512-bit PTK regardless of the negotiated cipher suite; this works for TKIP, but not for CCMP. Update the code to use proper PTK length based on the pairwise cipher. This fixed PTK derivation for both IEEE 802.11r and IEEE 802.11w (when using AKMP that specifies SHA-256-based key derivation). The fixed version does not interoperate with the previous versions. [Bug 307]

ChangeLog for wpa_supplicant
|
|
|
|
????-??-?? - v0.7.0
|
|
* increased wpa_cli ping interval to 5 seconds and made this
|
|
configurable with a new command line options (-G<seconds>)
|
|
* fixed scan buffer processing with WEXT to handle up to 65535
|
|
byte result buffer (previously, limited to 32768 bytes)
|
|
* allow multiple driver wrappers to be specified on command line
|
|
(e.g., -Dnl80211,wext); the first one that is able to initialize the
|
|
interface will be used
|
|
* added support for multiple SSIDs per scan request to optimize
|
|
scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
|
|
SSIDs); this requires driver support and can currently be used only
|
|
with nl80211
|
|
* added support for WPS USBA out-of-band mechanism with USB Flash
|
|
Drives (UFD) (CONFIG_WPS_UFD=y)
|
|
* driver_ndis: add PAE group address to the multicast address list to
|
|
fix wired IEEE 802.1X authentication
|
|
* fixed IEEE 802.11r key derivation function to match with the standard
|
|
(note: this breaks interoperability with previous version) [Bug 303]
|
|
* added better support for drivers that allow separate authentication
|
|
and association commands (e.g., mac80211-based Linux drivers with
|
|
nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
|
|
to be used (IEEE 802.11r)
|
|
* fixed SHA-256 based key derivation function to match with the
|
|
standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
|
|
(note: this breaks interoperability with previous version) [Bug 307]
|
|
|
|
2009-01-06 - v0.6.7
|
|
* added support for Wi-Fi Protected Setup (WPS)
|
|
(wpa_supplicant can now be configured to act as a WPS Enrollee to
|
|
enroll credentials for a network using PIN and PBC methods; in
|
|
addition, wpa_supplicant can act as a wireless WPS Registrar to
|
|
configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
|
|
into .config and setting the runtime configuration variables in
|
|
wpa_supplicant.conf (see WPS section in the example configuration
|
|
file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
|
|
manage WPS negotiation; see README-WPS for more details
|
|
* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
|
|
* added support for using driver_test over UDP socket
|
|
* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
|
|
2008 NPS; optional cryptobinding is now enabled (again) by default
|
|
* fixed PSK editing in wpa_gui
|
|
* changed EAP-GPSK to use the IANA assigned EAP method type 51
|
|
* added a Windows installer that includes WinPcap and all the needed
|
|
DLLs; in addition, it set up the registry automatically so that user
|
|
will only need start wpa_gui to get prompted to start the wpasvc
|
|
servide and add a new interface if needed through wpa_gui dialog
|
|
* updated management frame protection to use IEEE 802.11w/D7.0
|
|
|
|
2008-11-23 - v0.6.6
|
|
* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
|
|
(can be used to simulate test SIM/USIM card with a known private key;
|
|
enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
|
|
and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
|
|
* added a new network configuration option, wpa_ptk_rekey, that can be
|
|
used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
|
|
against TKIP deficiencies
|
|
* added an optional mitigation mechanism for certain attacks against
|
|
TKIP by delaying Michael MIC error reports by a random amount of time
|
|
between 0 and 60 seconds; this can be enabled with a build option
|
|
CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
|
|
* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
|
|
not bytes
|
|
* updated OpenSSL code for EAP-FAST to use an updated version of the
|
|
session ticket overriding API that was included into the upstream
|
|
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
|
|
needed with that version anymore)
|
|
* updated userspace MLME instructions to match with the current Linux
|
|
mac80211 implementation; please also note that this can only be used
|
|
with driver_nl80211.c (the old code from driver_wext.c was removed)
|
|
* added support (Linux only) for RoboSwitch chipsets (often found in
|
|
consumer grade routers); driver interface 'roboswitch'
|
|
* fixed canceling of PMKSA caching when using drivers that generate
|
|
RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
|
|
about
|
|
|
|
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)

|
|
[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
