ChangeLog for hostapd
2007-05-28 - v0.5.8
* updated driver_devicescape.c to build with the current
wireless-dev.git tree and net/d80211 changes
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
draft (draft-ietf-emu-eap-gpsk-03.txt)
* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
in Success Request [Bug 203]
* added support for sending EAP-AKA Notifications in error cases
* RADIUS server: added support for processing duplicate messages
(retransmissions from RADIUS client) by replying with the previous
reply
2006-12-31 - v0.5.7
* 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-PSK bit ordering of the Flags field
* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
by reading wpa_psk_file [Bug 181]
* fixed EAP-TTLS AVP parser processing for too short AVP lengths
* fixed IPv6 connection to RADIUS accounting server
2006-11-24 - v0.5.6
* added support for configuring and controlling multiple BSSes per
radio interface (bss=<ifname> in hostapd.conf); this is only
available with Devicescape and test driver interfaces
* fixed PMKSA cache update in the end of successful RSN
pre-authentication
* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
for each STA based on RADIUS Access-Accept attributes); this requires
VLAN support from the kernel driver/802.11 stack and this is
currently only available with Devicescape and test driver interfaces
* driver_madwifi: fixed configuration of unencrypted modes (plaintext
and IEEE 802.1X without WEP)
* 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.)
* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
parameters from a text file to make it possible to implement proper
GSM/UMTS authentication server for multiple SIM/USIM cards using
EAP-SIM/EAP-AKA
* fixed session timeout processing with drivers that do not use
ieee802_11.c (e.g., madwifi)
2006-08-27 - v0.5.5
* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
hostapd (e.g., to initialize wired network authentication based on an
external signal)
* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
using WPA2 even if PMKSA caching is not used
* added -P<pid file> argument for hostapd to write the current process
id into a file
* added support for RADIUS Authentication Server MIB (RFC 2619)
2006-06-20 - v0.5.4
* fixed nt_password_hash build [Bug 144]
* added PeerKey handshake implementation for IEEE 802.11e
direct link setup (DLS) to replace STAKey handshake
* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
draft-clancy-emu-eap-shared-secret-00.txt)
* fixed a segmentation fault when RSN pre-authentication was completed
successfully [Bug 152]
2006-04-27 - v0.5.3
* do not build nt_password_hash and hlr_auc_gw by default to avoid
requiring a TLS library for a successful build; these programs can be
build with 'make nt_password_hash' and 'make hlr_auc_gw'
* added a new configuration option, eapol_version, that can be used to
set EAPOL version to 1 (default is 2) to work around broken client
implementations that drop EAPOL frames which use version number 2
[Bug 89]
* added support for EAP-SAKE (no EAP method number allocated yet, so
this is using the same experimental type 255 as EAP-PSK)
* fixed EAP-MSCHAPv2 message length validation
2006-03-19 - v0.5.2
* fixed stdarg use in hostapd_logger(): if both stdout and syslog
logging was enabled, hostapd could trigger a segmentation fault in
vsyslog on some CPU -- C library combinations
* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
program to make it easier to use for implementing real SS7 gateway;
eap_sim_db is not anymore used as a file name for GSM authentication
triplets; instead, it is path to UNIX domain socket that will be used
to communicate with the external gateway program (e.g., hlr_auc_gw)
* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
local information (GSM authentication triplets from a text file and
hardcoded AKA authentication data); this can be used to test EAP-SIM
and EAP-AKA
* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
to make it possible to test EAP-AKA with real USIM cards (this is
disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
to enable this)
* driver_madwifi: added support for getting station RSN IE from
madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
broken with earlier change (r1357) in the driver
* changed EAP method registration to use a dynamic list of methods
instead of a static list generated at build time
* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
[Bug 125]
* added ap_max_inactivity configuration parameter
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 (test_socket=DIR:/tmp/test)
* added support for EAP expanded type (vendor specific EAP methods)
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)
* added support for EAP methods to use callbacks to external programs
by buffering a pending request and processing it after the EAP method
is ready to continue
* improved EAP-SIM database interface to allow external request to GSM
HLR/AuC without blocking hostapd process
* added support for using EAP-SIM pseudonyms and fast re-authentication
* added support for EAP-AKA in the integrated EAP authenticator
* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
user database to allow EAP-SIM/AKA selection without extra roundtrip
for EAP-Nak negotiation
* added support for storing EAP user password as NtPasswordHash instead
of plaintext password when using MSCHAP or MSCHAPv2 for
authentication (hash:<16-octet hex value>); added nt_password_hash
tool for hashing password to generate NtPasswordHash
2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
* driver_wired: fixed EAPOL sending to optionally use PAE group address
as the destination instead of supplicant MAC address; this is
disabled by default, but should be enabled with use_pae_group_addr=1
in configuration file if the wired interface is used by only one
device at the time (common switch configuration)
* driver_madwifi: configure driver to use TKIP countermeasures in order
to get correct behavior (IEEE 802.11 association failing; previously,
association succeeded, but hostpad forced disassociation immediately)
* driver_madwifi: added support for madwifi-ng
2005-10-27 - v0.4.6
* added support for replacing user identity from EAP with RADIUS
User-Name attribute from Access-Accept message, if that is included,
for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
tunneled identity into accounting messages when the RADIUS server
does not support better way of doing this with Class attribute)
* driver_madwifi: fixed EAPOL packet receive for configuration where
ath# is part of a bridge interface
* added a configuration file and log analyzer script for logwatch
* fixed EAPOL state machine step function to process all state
transitions before processing new events; this resolves a race
condition in which EAPOL-Start message could trigger hostapd to send
two EAP-Response/Identity frames to the authentication server
2005-09-25 - v0.4.5
* added client CA list to the TLS certificate request in order to make
it easier for the client to select which certificate to use
* added experimental support for EAP-PSK
* added support for WE-19 (hostap, madwifi)
2005-08-21 - v0.4.4
* fixed build without CONFIG_RSN_PREAUTH
* fixed FreeBSD build
2005-06-26 - v0.4.3
* fixed PMKSA caching to copy User-Name and Class attributes so that
RADIUS accounting gets correct information
* start RADIUS accounting only after successful completion of WPA
4-Way Handshake if WPA-PSK is used
* fixed PMKSA caching for the case where STA (re)associates without
first disassociating
2005-06-12 - v0.4.2
* EAP-PAX is now registered as EAP type 46
* fixed EAP-PAX MAC calculation
* fixed EAP-PAX CK and ICK key derivation
* renamed eap_authenticator configuration variable to eap_server to
better match with RFC 3748 (EAP) terminology
* 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
* fixed RADIUS server initialization when only auth or acct server
is configured and the other one is left empty
* driver_madwifi: added support for RADIUS accounting
* driver_madwifi: added preliminary support for compiling against 'BSD'
branch of madwifi CVS tree
* driver_madwifi: fixed pairwise key removal to allow WPA reauth
without disassociation
* added support for reading additional certificates from PKCS#12 files
and adding them to the certificate chain
* fixed RADIUS Class attribute processing to only use Access-Accept
packets to update Class; previously, other RADIUS authentication
packets could have cleared Class attribute
* added support for more than one Class attribute in RADIUS packets
* added support for verifying certificate revocation list (CRL) when
using integrated EAP authenticator for EAP-TLS; new hostapd.conf
options 'check_crl'; CRL must be included in the ca_cert file for now
2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
* added support for including network information into
EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
(e.g., to implement draft-adrange-eap-network-discovery-07.txt)
* fixed a bug which caused some RSN pre-authentication cases to use
freed memory and potentially crash hostapd
* fixed private key loading for cases where passphrase is not set
* added support for sending TLS alerts and aborting authentication
when receiving a TLS alert
* fixed WPA2 to add PMKSA cache entry when using integrated EAP
authenticator
* fixed PMKSA caching (EAP authentication was not skipped correctly
with the new state machine changes from IEEE 802.1X draft)
* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
to be added to .config to include IPv6 support); for RADIUS server,
radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
in RADIUS clients file can then use IPv6 format
* added experimental support for EAP-PAX
* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2005-01-23 - v0.3.5
* added support for configuring a forced PEAP version based on the
Phase 1 identity
* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
to terminate authentication
* fixed EAP identifier duplicate processing with the new IEEE 802.1X
draft
* clear accounting data in the driver when starting a new accounting
session
* driver_madwifi: filter wireless events based on ifindex to allow more
than one network interface to be used
* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
setting if the packet does not pass MIC verification (e.g., due to
incorrect PSK); previously, message 1/4 was not tried again if an
invalid message 2/4 was received
* fixed reconfiguration of RADIUS client retransmission timer when
adding a new message to the pending list; previously, timer was not
updated at this point and if there was a pending message with long
time for the next retry, the new message needed to wait that long for
its first retry, too
2005-01-09 - v0.3.4
* added support for configuring multiple allowed EAP types for Phase 2
authentication (EAP-PEAP, EAP-TTLS)
* fixed EAPOL-Start processing to trigger WPA reauthentication
(previously, only EAPOL authentication was done)
2005-01-02 - v0.3.3
* added support for EAP-PEAP in the integrated EAP authenticator
* added support for EAP-GTC in the integrated EAP authenticator
* added support for configuring list of EAP methods for Phase 1 so that
the integrated EAP authenticator can, e.g., use the wildcard entry
for EAP-TLS and EAP-PEAP
* added support for EAP-TTLS in the integrated EAP authenticator
* added support for EAP-SIM in the integrated EAP authenticator
* added support for using hostapd as a RADIUS authentication server
with the integrated EAP authenticator taking care of EAP
authentication (new hostapd.conf options: radius_server_clients and
radius_server_auth_port); this is not included in default build; use
CONFIG_RADIUS_SERVER=y in .config to include
2004-12-19 - v0.3.2
* removed 'daemonize' configuration file option since it has not really
been used at all for more than year
* driver_madwifi: fixed group key setup and added get_ssid method
* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
2004-12-12 - v0.3.1
* added support for integrated EAP-TLS authentication (new hostapd.conf
variables: ca_cert, server_cert, private_key, private_key_passwd);
this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
external RADIUS server
* added support for reading PKCS#12 (PFX) files (as a replacement for
PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
* added support for Acct-{Input,Output}-Gigawords
* added support for Event-Timestamp (in RADIUS Accounting-Requests)
* added support for RADIUS Authentication Client MIB (RFC2618)
* added support for RADIUS Accounting Client MIB (RFC2620)
* made EAP re-authentication period configurable (eap_reauth_period)
* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
* fixed EAPOL state machine to stop if STA is removed during
eapol_sm_step(); this fixes at least one segfault triggering bug with
IEEE 802.11i pre-authentication
* added support for multiple WPA pre-shared keys (e.g., one for each
client MAC address or keys shared by a group of clients);
new hostapd.conf field wpa_psk_file for setting path to a text file
containing PSKs, see hostapd.wpa_psk for an example
* added support for multiple driver interfaces to allow hostapd to be
used with other drivers
* added wired authenticator driver interface (driver=wired in
hostapd.conf, see wired.conf for example configuration)
* added madwifi driver interface (driver=madwifi in hostapd.conf, see
madwifi.conf for example configuration; Note: include files from
madwifi project is needed for building and a configuration file,
.config, needs to be created in hostapd directory with
CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
build)
* fixed an alignment issue that could cause SHA-1 to fail on some
platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
align variables)
* fixed RADIUS reconnection after an error in sending interim
accounting packets
* added hostapd control interface for external programs and an example
CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
'hostapd_cli sta <addr>')
* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
* added support for strict GTK rekeying (wpa_strict_rekey in
hostapd.conf)
* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
(instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
IEEE 802.11F-2003)
* added Prism54 driver interface (driver=prism54 in hostapd.conf;
note: .config needs to be created in hostapd directory with
CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
build)
* dual-licensed hostapd (GPLv2 and BSD licenses)
* fixed RADIUS accounting to generate a new session id for cases where
a station reassociates without first being complete deauthenticated
* fixed STA disassociation handler to mark next timeout state to
deauthenticate the station, i.e., skip long wait for inactivity poll
and extra disassociation, if the STA disassociates without
deauthenticating
* added integrated EAP authenticator that can be used instead of
external RADIUS authentication server; currently, only EAP-MD5 is
supported, so this cannot yet be used for key distribution; the EAP
method interface is generic, though, so adding new EAP methods should
be straightforward; new hostapd.conf variables: 'eap_authenticator'
and 'eap_user_file'; this obsoletes "minimal authentication server"
('minimal_eap' in hostapd.conf) which is now removed
* added support for FreeBSD and driver interface for the BSD net80211
layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
.config); please note that some of the required kernel mods have not
yet been committed
2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
* fixed some accounting cases where Accounting-Start was sent when
IEEE 802.1X port was being deauthorized
2004-06-20 - v0.2.3
* modified RADIUS client to re-connect the socket in case of certain
error codes that are generated when a network interface state is
changes (e.g., when IP address changes or the interface is set UP)
* fixed couple of cases where EAPOL state for a station was freed
twice causing a segfault for hostapd
* fixed couple of bugs in processing WPA deauthentication (freed data
was used)
2004-05-31 - v0.2.2
* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
cases where STAs dropped multicast frames as replay attacks
* added support for copying RADIUS Attribute 'Class' from
authentication messages into accounting messages
* send canned EAP failure if RADIUS server sends Access-Reject without
EAP message (previously, Supplicant was not notified in this case)
* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
not start EAPOL state machines if the STA selected to use WPA-PSK)
2004-05-06 - v0.2.1
* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
- based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
(i.e., IEEE 802.11i/D3.0)
- supports WPA-only, RSN-only, and mixed WPA/RSN mode
- both WPA-PSK and WPA-RADIUS/EAP are supported
- PMKSA caching and pre-authentication
- new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
rsn_preauth, rsn_preauth_interfaces
* fixed interim accounting to remove any pending accounting messages
to the STA before sending a new one
2004-02-15 - v0.2.0
* added support for Acct-Interim-Interval:
- draft-ietf-radius-acct-interim-01.txt
- use Acct-Interim-Interval attribute from Access-Accept if local
'radius_acct_interim_interval' is not set
- allow different update intervals for each STA
* fixed event loop to call signal handlers only after returning from
the real signal handler
* reset sta->timeout_next after successful association to make sure
that the previously registered inactivity timer will not remove the
STA immediately (e.g., if STA deauthenticates and re-associates
before the timer is triggered).
* added new hostapd.conf variable, nas_identifier, that can be used to
add an optional RADIUS Attribute, NAS-Identifier, into authentication
and accounting messages
* added support for Accounting-On and Accounting-Off messages
* fixed accounting session handling to send Accounting-Start only once
per session and not to send Accounting-Stop if the session was not
initialized properly
* fixed Accounting-Stop statistics in cases where the message was
previously sent after the kernel entry for the STA (and/or IEEE
802.1X data) was removed
Note:
Older changes up to and including v0.1.0 are included in the ChangeLog
of the Host AP driver.
