ChangeLog for wpa_supplicant
|
|
|
|
2005-06-10 - v0.3.9
|
|
* 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
|
|
* 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
|
|
* fixed a possible double free in EAP-TTLS fast-reauthentication when
|
|
identity or password is entered through control interface
|
|
* added -P<pid file> argument for wpa_supplicant to write the current
|
|
process id into a file
|
|
* driver_madwifi: fixed association in plaintext mode
|
|
* driver_madwifi: added preliminary support for compiling against 'BSD'
|
|
branch of madwifi CVS tree
|
|
* 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
|
|
* 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)
|
|
* driver_broadcom: fixed couple of memory leaks in scan result
|
|
processing
|
|
|
|
2005-02-13 - v0.3.8
|
|
* fixed EAPOL-Key validation to drop packets with invalid Key Data
|
|
Length; such frames could have crashed wpa_supplicant due to buffer
|
|
overflow
|
|
|
|
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

- 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, ..)
