4 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
5 logging was enabled, hostapd could trigger a segmentation fault in
6 vsyslog on some CPU -- C library combinations
8 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
9 * driver_wired: fixed EAPOL sending to optionally use PAE group address
10 as the destination instead of supplicant MAC address; this is
11 disabled by default, but should be enabled with use_pae_group_addr=1
12 in configuration file if the wired interface is used by only one
13 device at the time (common switch configuration)
14 * driver_madwifi: configure driver to use TKIP countermeasures in order
15 to get correct behavior (IEEE 802.11 association failing; previously,
16 association succeeded, but hostpad forced disassociation immediately)
17 * driver_madwifi: added support for madwifi-ng
20 * added support for replacing user identity from EAP with RADIUS
21 User-Name attribute from Access-Accept message, if that is included,
22 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
23 tunneled identity into accounting messages when the RADIUS server
24 does not support better way of doing this with Class attribute)
25 * driver_madwifi: fixed EAPOL packet receive for configuration where
26 ath# is part of a bridge interface
27 * added a configuration file and log analyzer script for logwatch
28 * fixed EAPOL state machine step function to process all state
29 transitions before processing new events; this resolves a race
30 condition in which EAPOL-Start message could trigger hostapd to send
31 two EAP-Response/Identity frames to the authentication server
34 * added client CA list to the TLS certificate request in order to make
35 it easier for the client to select which certificate to use
36 * added experimental support for EAP-PSK
37 * added support for WE-19 (hostap, madwifi)
40 * fixed build without CONFIG_RSN_PREAUTH
44 * fixed PMKSA caching to copy User-Name and Class attributes so that
45 RADIUS accounting gets correct information
46 * start RADIUS accounting only after successful completion of WPA
47 4-Way Handshake if WPA-PSK is used
48 * fixed PMKSA caching for the case where STA (re)associates without
52 * EAP-PAX is now registered as EAP type 46
53 * fixed EAP-PAX MAC calculation
54 * fixed EAP-PAX CK and ICK key derivation
55 * renamed eap_authenticator configuration variable to eap_server to
56 better match with RFC 3748 (EAP) terminology
57 * driver_test: added support for testing hostapd with wpa_supplicant
58 by using test driver interface without any kernel drivers or network
62 * fixed RADIUS server initialization when only auth or acct server
63 is configured and the other one is left empty
64 * driver_madwifi: added support for RADIUS accounting
65 * driver_madwifi: added preliminary support for compiling against 'BSD'
66 branch of madwifi CVS tree
67 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
68 without disassociation
69 * added support for reading additional certificates from PKCS#12 files
70 and adding them to the certificate chain
71 * fixed RADIUS Class attribute processing to only use Access-Accept
72 packets to update Class; previously, other RADIUS authentication
73 packets could have cleared Class attribute
74 * added support for more than one Class attribute in RADIUS packets
75 * added support for verifying certificate revocation list (CRL) when
76 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
77 options 'check_crl'; CRL must be included in the ca_cert file for now
79 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
80 * added support for including network information into
81 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
82 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
83 * fixed a bug which caused some RSN pre-authentication cases to use
84 freed memory and potentially crash hostapd
85 * fixed private key loading for cases where passphrase is not set
86 * added support for sending TLS alerts and aborting authentication
87 when receiving a TLS alert
88 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
90 * fixed PMKSA caching (EAP authentication was not skipped correctly
91 with the new state machine changes from IEEE 802.1X draft)
92 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
93 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
94 to be added to .config to include IPv6 support); for RADIUS server,
95 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
96 in RADIUS clients file can then use IPv6 format
97 * added experimental support for EAP-PAX
98 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
99 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
101 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
104 * added support for configuring a forced PEAP version based on the
106 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
107 to terminate authentication
108 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
110 * clear accounting data in the driver when starting a new accounting
112 * driver_madwifi: filter wireless events based on ifindex to allow more
113 than one network interface to be used
114 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
115 setting if the packet does not pass MIC verification (e.g., due to
116 incorrect PSK); previously, message 1/4 was not tried again if an
117 invalid message 2/4 was received
118 * fixed reconfiguration of RADIUS client retransmission timer when
119 adding a new message to the pending list; previously, timer was not
120 updated at this point and if there was a pending message with long
121 time for the next retry, the new message needed to wait that long for
125 * added support for configuring multiple allowed EAP types for Phase 2
126 authentication (EAP-PEAP, EAP-TTLS)
127 * fixed EAPOL-Start processing to trigger WPA reauthentication
128 (previously, only EAPOL authentication was done)
131 * added support for EAP-PEAP in the integrated EAP authenticator
132 * added support for EAP-GTC in the integrated EAP authenticator
133 * added support for configuring list of EAP methods for Phase 1 so that
134 the integrated EAP authenticator can, e.g., use the wildcard entry
135 for EAP-TLS and EAP-PEAP
136 * added support for EAP-TTLS in the integrated EAP authenticator
137 * added support for EAP-SIM in the integrated EAP authenticator
138 * added support for using hostapd as a RADIUS authentication server
139 with the integrated EAP authenticator taking care of EAP
140 authentication (new hostapd.conf options: radius_server_clients and
141 radius_server_auth_port); this is not included in default build; use
142 CONFIG_RADIUS_SERVER=y in .config to include
145 * removed 'daemonize' configuration file option since it has not really
146 been used at all for more than year
147 * driver_madwifi: fixed group key setup and added get_ssid method
148 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
151 * added support for integrated EAP-TLS authentication (new hostapd.conf
152 variables: ca_cert, server_cert, private_key, private_key_passwd);
153 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
154 external RADIUS server
155 * added support for reading PKCS#12 (PFX) files (as a replacement for
156 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
158 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
159 * added support for Acct-{Input,Output}-Gigawords
160 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
161 * added support for RADIUS Authentication Client MIB (RFC2618)
162 * added support for RADIUS Accounting Client MIB (RFC2620)
163 * made EAP re-authentication period configurable (eap_reauth_period)
164 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
165 * fixed EAPOL state machine to stop if STA is removed during
166 eapol_sm_step(); this fixes at least one segfault triggering bug with
167 IEEE 802.11i pre-authentication
168 * added support for multiple WPA pre-shared keys (e.g., one for each
169 client MAC address or keys shared by a group of clients);
170 new hostapd.conf field wpa_psk_file for setting path to a text file
171 containing PSKs, see hostapd.wpa_psk for an example
172 * added support for multiple driver interfaces to allow hostapd to be
173 used with other drivers
174 * added wired authenticator driver interface (driver=wired in
175 hostapd.conf, see wired.conf for example configuration)
176 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
177 madwifi.conf for example configuration; Note: include files from
178 madwifi project is needed for building and a configuration file,
179 .config, needs to be created in hostapd directory with
180 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
182 * fixed an alignment issue that could cause SHA-1 to fail on some
183 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
185 * fixed RADIUS reconnection after an error in sending interim
187 * added hostapd control interface for external programs and an example
188 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
189 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
190 'hostapd_cli sta <addr>')
191 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
192 * added support for strict GTK rekeying (wpa_strict_rekey in
194 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
195 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
197 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
198 note: .config needs to be created in hostapd directory with
199 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
201 * dual-licensed hostapd (GPLv2 and BSD licenses)
202 * fixed RADIUS accounting to generate a new session id for cases where
203 a station reassociates without first being complete deauthenticated
204 * fixed STA disassociation handler to mark next timeout state to
205 deauthenticate the station, i.e., skip long wait for inactivity poll
206 and extra disassociation, if the STA disassociates without
208 * added integrated EAP authenticator that can be used instead of
209 external RADIUS authentication server; currently, only EAP-MD5 is
210 supported, so this cannot yet be used for key distribution; the EAP
211 method interface is generic, though, so adding new EAP methods should
212 be straightforward; new hostapd.conf variables: 'eap_authenticator'
213 and 'eap_user_file'; this obsoletes "minimal authentication server"
214 ('minimal_eap' in hostapd.conf) which is now removed
215 * added support for FreeBSD and driver interface for the BSD net80211
216 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
217 .config); please note that some of the required kernel mods have not
220 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
221 * fixed some accounting cases where Accounting-Start was sent when
222 IEEE 802.1X port was being deauthorized
225 * modified RADIUS client to re-connect the socket in case of certain
226 error codes that are generated when a network interface state is
227 changes (e.g., when IP address changes or the interface is set UP)
228 * fixed couple of cases where EAPOL state for a station was freed
229 twice causing a segfault for hostapd
230 * fixed couple of bugs in processing WPA deauthentication (freed data
234 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
235 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
236 cases where STAs dropped multicast frames as replay attacks
237 * added support for copying RADIUS Attribute 'Class' from
238 authentication messages into accounting messages
239 * send canned EAP failure if RADIUS server sends Access-Reject without
240 EAP message (previously, Supplicant was not notified in this case)
241 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
242 not start EAPOL state machines if the STA selected to use WPA-PSK)
245 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
246 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
247 (i.e., IEEE 802.11i/D3.0)
248 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
249 - both WPA-PSK and WPA-RADIUS/EAP are supported
250 - PMKSA caching and pre-authentication
251 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
252 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
253 rsn_preauth, rsn_preauth_interfaces
254 * fixed interim accounting to remove any pending accounting messages
255 to the STA before sending a new one
258 * added support for Acct-Interim-Interval:
259 - draft-ietf-radius-acct-interim-01.txt
260 - use Acct-Interim-Interval attribute from Access-Accept if local
261 'radius_acct_interim_interval' is not set
262 - allow different update intervals for each STA
263 * fixed event loop to call signal handlers only after returning from
264 the real signal handler
265 * reset sta->timeout_next after successful association to make sure
266 that the previously registered inactivity timer will not remove the
267 STA immediately (e.g., if STA deauthenticates and re-associates
268 before the timer is triggered).
269 * added new hostapd.conf variable, nas_identifier, that can be used to
270 add an optional RADIUS Attribute, NAS-Identifier, into authentication
271 and accounting messages
272 * added support for Accounting-On and Accounting-Off messages
273 * fixed accounting session handling to send Accounting-Start only once
274 per session and not to send Accounting-Stop if the session was not
276 * fixed Accounting-Stop statistics in cases where the message was
277 previously sent after the kernel entry for the STA (and/or IEEE
278 802.1X data) was removed
283 Older changes up to and including v0.1.0 are included in the ChangeLog
284 of the Host AP driver.
