1ChangeLog for hostapd 2 32010-01-12 - v0.6.10 4 * fixed SHA-256 based key derivation function to match with the 5 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 6 (note: this breaks interoperability with previous version) [Bug 307] 7 * fixed WPS selected registrar expiration for internal PIN registrar 8 * disable PMTU discovery for RADIUS packets 9 * fixed WPS UPnP SSDP on 32-bit targets 10 * fixed WPS AP reconfiguration with drivers that do not use hostapd 11 MLME 12 * fixed RSN parameter setting for multi-BSS case 13 * added WPS workarounds for known interoperability issues with broken, 14 deployed implementation 15 * update IEEE 802.11w implementation to match with the published 16 standard 17 * fixed OpCode when proxying WSC_ACK or WSC_NACK from WPS ER 18 * fixed proxying of WSC_NACK to WPS ER 19 * fixed compilation with newer GnuTLS versions 20 * added support for defining timeout for WPS PINs 21 * fixed WPS Probe Request processing to handle missing required 22 attribute 23 * fixed PKCS#12 use with OpenSSL 1.0.0 24 252009-03-23 - v0.6.9 26 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 27 reported correctly; TX/RX packets not yet available from kernel) 28 * fixed EAPOL/EAP reauthentication when using an external RADIUS 29 authentication server 30 * driver_prism54: fixed segmentation fault on initialization 31 * fixed TNC with EAP-TTLS 32 * fixed IEEE 802.11r key derivation function to match with the standard 33 (note: this breaks interoperability with previous version) [Bug 303] 34 352009-02-15 - v0.6.8 36 * increased hostapd_cli ping interval to 5 seconds and made this 37 configurable with a new command line options (-G<seconds>) 38 * driver_nl80211: use Linux socket filter to improve performance 39 * added support for external Registrars with WPS (UPnP transport) 40 412009-01-06 - v0.6.7 42 * added support for Wi-Fi Protected Setup (WPS) 43 (hostapd can now be configured to act as an integrated WPS Registrar 44 and provision credentials for WPS Enrollees using PIN and PBC 45 methods; external wireless Registrar can configure the AP, but 46 external WLAN Manager Registrars are not supported); WPS support can 47 be enabled by adding CONFIG_WPS=y into .config and setting the 48 runtime configuration variables in hostapd.conf (see WPS section in 49 the example configuration file); new hostapd_cli commands wps_pin and 50 wps_pbc are used to configure WPS negotiation; see README-WPS for 51 more details 52 * added IEEE 802.11n HT capability configuration (ht_capab) 53 * added support for generating Country IE based on nl80211 regulatory 54 information (added if ieee80211d=1 in configuration) 55 * fixed WEP authentication (both Open System and Shared Key) with 56 mac80211 57 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 58 * added support for using driver_test over UDP socket 59 * changed EAP-GPSK to use the IANA assigned EAP method type 51 60 * updated management frame protection to use IEEE 802.11w/D7.0 61 * fixed retransmission of EAP requests if no response is received 62 632008-11-23 - v0.6.6 64 * added a new configuration option, wpa_ptk_rekey, that can be used to 65 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 66 TKIP deficiencies 67 * updated OpenSSL code for EAP-FAST to use an updated version of the 68 session ticket overriding API that was included into the upstream 69 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 70 needed with that version anymore) 71 * changed channel flags configuration to read the information from 72 the driver (e.g., via driver_nl80211 when using mac80211) instead of 73 using hostapd as the source of the regulatory information (i.e., 74 information from CRDA is now used with mac80211); this allows 5 GHz 75 channels to be used with hostapd (if allowed in the current 76 regulatory domain) 77 * fixed EAP-TLS message processing for the last TLS message if it is 78 large enough to require fragmentation (e.g., if a large Session 79 Ticket data is included) 80 * fixed listen interval configuration for nl80211 drivers 81 822008-11-01 - v0.6.5 83 * added support for SHA-256 as X.509 certificate digest when using the 84 internal X.509/TLSv1 implementation 85 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 86 identity lengths) 87 * fixed internal TLSv1 implementation for abbreviated handshake (used 88 by EAP-FAST server) 89 * added support for setting VLAN ID for STAs based on local MAC ACL 90 (accept_mac_file) as an alternative for RADIUS server-based 91 configuration 92 * updated management frame protection to use IEEE 802.11w/D6.0 93 (adds a new association ping to protect against unauthenticated 94 authenticate or (re)associate request frames dropping association) 95 * added support for using SHA256-based stronger key derivation for WPA2 96 (IEEE 802.11w) 97 * added new "driver wrapper" for RADIUS-only configuration 98 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 99 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 100 is enabled in configuration 101 * changed EAP-FAST configuration to use separate fields for A-ID and 102 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 103 16-octet len binary value for better interoperability with some peer 104 implementations; eap_fast_a_id is now configured as a hex string 105 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 106 configuration (wireless-testing.git and Linux kernel releases 107 starting from 2.6.29) 108 1092008-08-10 - v0.6.4 110 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 111 Identity Request if identity is already known 112 * added support for EAP Sequences in EAP-FAST Phase 2 113 * added support for EAP-TNC (Trusted Network Connect) 114 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 115 changes needed to run two methods in sequence (IF-T) and the IF-IMV 116 and IF-TNCCS interfaces from TNCS) 117 * added support for optional cryptobinding with PEAPv0 118 * added fragmentation support for EAP-TNC 119 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 120 data 121 * added support for opportunistic key caching (OKC) 122 1232008-02-22 - v0.6.3 124 * fixed Reassociation Response callback processing when using internal 125 MLME (driver_{hostap,nl80211,test}.c) 126 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 127 * copy optional Proxy-State attributes into RADIUS response when acting 128 as a RADIUS authentication server 129 * fixed EAPOL state machine to handle a case in which no response is 130 received from the RADIUS authentication server; previous version 131 could have triggered a crash in some cases after a timeout 132 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 133 be used 134 * added a workaround for EAP-SIM/AKA peers that include incorrect null 135 termination in the username 136 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 137 attribute in notification messages only when using fast 138 reauthentication 139 * fixed EAP-SIM Start response processing for fast reauthentication 140 case 141 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 142 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 143 1442008-01-01 - v0.6.2 145 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 146 lengths properly to avoid potential crash caused by invalid messages 147 * added data structure for storing allocated buffers (struct wpabuf); 148 this does not affect hostapd usage, but many of the APIs changed 149 and various interfaces (e.g., EAP) is not compatible with old 150 versions 151 * added support for protecting EAP-AKA/Identity messages with 152 AT_CHECKCODE (optional feature in RFC 4187) 153 * added support for protected result indication with AT_RESULT_IND for 154 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 155 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 156 EAP server configuration; previously all four were enabled for every 157 phase 2 user, now all four are disabled by default and need to be 158 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 159 TTLS-MSCHAPV2 160 * removed old debug printing mechanism and the related 'debug' 161 parameter in the configuration file; debug verbosity is now set with 162 -d (or -dd) command line arguments 163 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 164 only shared key/password authentication is supported in this version 165 1662007-11-24 - v0.6.1 167 * added experimental, integrated TLSv1 server implementation with the 168 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 169 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 170 .config); this can be useful, e.g., if the target system does not 171 have a suitable TLS library and a minimal code size is required 172 * added support for EAP-FAST server method to the integrated EAP 173 server 174 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 175 draft (draft-ietf-emu-eap-gpsk-07.txt) 176 * added a new configuration parameter, rsn_pairwise, to allow different 177 pairwise cipher suites to be enabled for WPA and RSN/WPA2 178 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 179 either need to support this or will have to use the WPA/RSN IEs from 180 hostapd; currently, the included madwifi and bsd driver interfaces do 181 not have support for this) 182 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 183 1842007-05-28 - v0.6.0 185 * added experimental IEEE 802.11r/D6.0 support 186 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 187 * updated EAP-PSK to use the IANA-allocated EAP type 47 188 * fixed EAP-PSK bit ordering of the Flags field 189 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 190 by reading wpa_psk_file [Bug 181] 191 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 192 * fixed IPv6 connection to RADIUS accounting server 193 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 194 draft (draft-ietf-emu-eap-gpsk-04.txt) 195 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 196 entries instead of only using the same three triplets every time 197 (this does not work properly with tests using multiple clients, but 198 provides bit better triplet data for testing a single client; anyway, 199 if a better quality triplets are needed, GSM-Milenage should be used 200 instead of hardcoded triplet file) 201 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 202 in Success Request [Bug 203] 203 * added support for sending EAP-AKA Notifications in error cases 204 * updated to use IEEE 802.11w/D2.0 for management frame protection 205 (still experimental) 206 * RADIUS server: added support for processing duplicate messages 207 (retransmissions from RADIUS client) by replying with the previous 208 reply 209 2102006-11-24 - v0.5.6 211 * added support for configuring and controlling multiple BSSes per 212 radio interface (bss=<ifname> in hostapd.conf); this is only 213 available with Devicescape and test driver interfaces 214 * fixed PMKSA cache update in the end of successful RSN 215 pre-authentication 216 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 217 for each STA based on RADIUS Access-Accept attributes); this requires 218 VLAN support from the kernel driver/802.11 stack and this is 219 currently only available with Devicescape and test driver interfaces 220 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 221 and IEEE 802.1X without WEP) 222 * removed STAKey handshake since PeerKey handshake has replaced it in 223 IEEE 802.11ma and there are no known deployments of STAKey 224 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 225 draft (draft-ietf-emu-eap-gpsk-01.txt) 226 * added preliminary implementation of IEEE 802.11w/D1.0 (management 227 frame protection) 228 (Note: this requires driver support to work properly.) 229 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 230 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 231 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 232 parameters from a text file to make it possible to implement proper 233 GSM/UMTS authentication server for multiple SIM/USIM cards using 234 EAP-SIM/EAP-AKA 235 * fixed session timeout processing with drivers that do not use 236 ieee802_11.c (e.g., madwifi) 237 2382006-08-27 - v0.5.5 239 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 240 hostapd (e.g., to initialize wired network authentication based on an 241 external signal) 242 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 243 using WPA2 even if PMKSA caching is not used 244 * added -P<pid file> argument for hostapd to write the current process 245 id into a file 246 * added support for RADIUS Authentication Server MIB (RFC 2619) 247 2482006-06-20 - v0.5.4 249 * fixed nt_password_hash build [Bug 144] 250 * added PeerKey handshake implementation for IEEE 802.11e 251 direct link setup (DLS) to replace STAKey handshake 252 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 253 draft-clancy-emu-eap-shared-secret-00.txt) 254 * fixed a segmentation fault when RSN pre-authentication was completed 255 successfully [Bug 152] 256 2572006-04-27 - v0.5.3 258 * do not build nt_password_hash and hlr_auc_gw by default to avoid 259 requiring a TLS library for a successful build; these programs can be 260 build with 'make nt_password_hash' and 'make hlr_auc_gw' 261 * added a new configuration option, eapol_version, that can be used to 262 set EAPOL version to 1 (default is 2) to work around broken client 263 implementations that drop EAPOL frames which use version number 2 264 [Bug 89] 265 * added support for EAP-SAKE (no EAP method number allocated yet, so 266 this is using the same experimental type 255 as EAP-PSK) 267 * fixed EAP-MSCHAPv2 message length validation 268 2692006-03-19 - v0.5.2 270 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 271 logging was enabled, hostapd could trigger a segmentation fault in 272 vsyslog on some CPU -- C library combinations 273 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 274 program to make it easier to use for implementing real SS7 gateway; 275 eap_sim_db is not anymore used as a file name for GSM authentication 276 triplets; instead, it is path to UNIX domain socket that will be used 277 to communicate with the external gateway program (e.g., hlr_auc_gw) 278 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 279 local information (GSM authentication triplets from a text file and 280 hardcoded AKA authentication data); this can be used to test EAP-SIM 281 and EAP-AKA 282 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 283 to make it possible to test EAP-AKA with real USIM cards (this is 284 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 285 to enable this) 286 * driver_madwifi: added support for getting station RSN IE from 287 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 288 broken with earlier change (r1357) in the driver 289 * changed EAP method registration to use a dynamic list of methods 290 instead of a static list generated at build time 291 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 292 [Bug 125] 293 * added ap_max_inactivity configuration parameter 294 2952006-01-29 - v0.5.1 296 * driver_test: added better support for multiple APs and STAs by using 297 a directory with sockets that include MAC address for each device in 298 the name (test_socket=DIR:/tmp/test) 299 * added support for EAP expanded type (vendor specific EAP methods) 300 3012005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 302 * added experimental STAKey handshake implementation for IEEE 802.11e 303 direct link setup (DLS); note: this is disabled by default in both 304 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 305 and stakey=1) 306 * added support for EAP methods to use callbacks to external programs 307 by buffering a pending request and processing it after the EAP method 308 is ready to continue 309 * improved EAP-SIM database interface to allow external request to GSM 310 HLR/AuC without blocking hostapd process 311 * added support for using EAP-SIM pseudonyms and fast re-authentication 312 * added support for EAP-AKA in the integrated EAP authenticator 313 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 314 user database to allow EAP-SIM/AKA selection without extra roundtrip 315 for EAP-Nak negotiation 316 * added support for storing EAP user password as NtPasswordHash instead 317 of plaintext password when using MSCHAP or MSCHAPv2 for 318 authentication (hash:<16-octet hex value>); added nt_password_hash 319 tool for hashing password to generate NtPasswordHash 320 3212005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 322 * driver_wired: fixed EAPOL sending to optionally use PAE group address 323 as the destination instead of supplicant MAC address; this is 324 disabled by default, but should be enabled with use_pae_group_addr=1 325 in configuration file if the wired interface is used by only one 326 device at the time (common switch configuration) 327 * driver_madwifi: configure driver to use TKIP countermeasures in order 328 to get correct behavior (IEEE 802.11 association failing; previously, 329 association succeeded, but hostpad forced disassociation immediately) 330 * driver_madwifi: added support for madwifi-ng 331 3322005-10-27 - v0.4.6 333 * added support for replacing user identity from EAP with RADIUS 334 User-Name attribute from Access-Accept message, if that is included, 335 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 336 tunneled identity into accounting messages when the RADIUS server 337 does not support better way of doing this with Class attribute) 338 * driver_madwifi: fixed EAPOL packet receive for configuration where 339 ath# is part of a bridge interface 340 * added a configuration file and log analyzer script for logwatch 341 * fixed EAPOL state machine step function to process all state 342 transitions before processing new events; this resolves a race 343 condition in which EAPOL-Start message could trigger hostapd to send 344 two EAP-Response/Identity frames to the authentication server 345 3462005-09-25 - v0.4.5 347 * added client CA list to the TLS certificate request in order to make 348 it easier for the client to select which certificate to use 349 * added experimental support for EAP-PSK 350 * added support for WE-19 (hostap, madwifi) 351 3522005-08-21 - v0.4.4 353 * fixed build without CONFIG_RSN_PREAUTH 354 * fixed FreeBSD build 355 3562005-06-26 - v0.4.3 357 * fixed PMKSA caching to copy User-Name and Class attributes so that 358 RADIUS accounting gets correct information 359 * start RADIUS accounting only after successful completion of WPA 360 4-Way Handshake if WPA-PSK is used 361 * fixed PMKSA caching for the case where STA (re)associates without 362 first disassociating 363 3642005-06-12 - v0.4.2 365 * EAP-PAX is now registered as EAP type 46 366 * fixed EAP-PAX MAC calculation 367 * fixed EAP-PAX CK and ICK key derivation 368 * renamed eap_authenticator configuration variable to eap_server to 369 better match with RFC 3748 (EAP) terminology 370 * driver_test: added support for testing hostapd with wpa_supplicant 371 by using test driver interface without any kernel drivers or network 372 cards 373 3742005-05-22 - v0.4.1 375 * fixed RADIUS server initialization when only auth or acct server 376 is configured and the other one is left empty 377 * driver_madwifi: added support for RADIUS accounting 378 * driver_madwifi: added preliminary support for compiling against 'BSD' 379 branch of madwifi CVS tree 380 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 381 without disassociation 382 * added support for reading additional certificates from PKCS#12 files 383 and adding them to the certificate chain 384 * fixed RADIUS Class attribute processing to only use Access-Accept 385 packets to update Class; previously, other RADIUS authentication 386 packets could have cleared Class attribute 387 * added support for more than one Class attribute in RADIUS packets 388 * added support for verifying certificate revocation list (CRL) when 389 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 390 options 'check_crl'; CRL must be included in the ca_cert file for now 391 3922005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 393 * added support for including network information into 394 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 395 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 396 * fixed a bug which caused some RSN pre-authentication cases to use 397 freed memory and potentially crash hostapd 398 * fixed private key loading for cases where passphrase is not set 399 * added support for sending TLS alerts and aborting authentication 400 when receiving a TLS alert 401 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 402 authenticator 403 * fixed PMKSA caching (EAP authentication was not skipped correctly 404 with the new state machine changes from IEEE 802.1X draft) 405 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 406 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 407 to be added to .config to include IPv6 support); for RADIUS server, 408 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 409 in RADIUS clients file can then use IPv6 format 410 * added experimental support for EAP-PAX 411 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 412 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 413 4142005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 415 4162005-01-23 - v0.3.5 417 * added support for configuring a forced PEAP version based on the 418 Phase 1 identity 419 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 420 to terminate authentication 421 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 422 draft 423 * clear accounting data in the driver when starting a new accounting 424 session 425 * driver_madwifi: filter wireless events based on ifindex to allow more 426 than one network interface to be used 427 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 428 setting if the packet does not pass MIC verification (e.g., due to 429 incorrect PSK); previously, message 1/4 was not tried again if an 430 invalid message 2/4 was received 431 * fixed reconfiguration of RADIUS client retransmission timer when 432 adding a new message to the pending list; previously, timer was not 433 updated at this point and if there was a pending message with long 434 time for the next retry, the new message needed to wait that long for 435 its first retry, too 436 4372005-01-09 - v0.3.4 438 * added support for configuring multiple allowed EAP types for Phase 2 439 authentication (EAP-PEAP, EAP-TTLS) 440 * fixed EAPOL-Start processing to trigger WPA reauthentication 441 (previously, only EAPOL authentication was done) 442 4432005-01-02 - v0.3.3 444 * added support for EAP-PEAP in the integrated EAP authenticator 445 * added support for EAP-GTC in the integrated EAP authenticator 446 * added support for configuring list of EAP methods for Phase 1 so that 447 the integrated EAP authenticator can, e.g., use the wildcard entry 448 for EAP-TLS and EAP-PEAP 449 * added support for EAP-TTLS in the integrated EAP authenticator 450 * added support for EAP-SIM in the integrated EAP authenticator 451 * added support for using hostapd as a RADIUS authentication server 452 with the integrated EAP authenticator taking care of EAP 453 authentication (new hostapd.conf options: radius_server_clients and 454 radius_server_auth_port); this is not included in default build; use 455 CONFIG_RADIUS_SERVER=y in .config to include 456 4572004-12-19 - v0.3.2 458 * removed 'daemonize' configuration file option since it has not really 459 been used at all for more than year 460 * driver_madwifi: fixed group key setup and added get_ssid method 461 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 462 4632004-12-12 - v0.3.1 464 * added support for integrated EAP-TLS authentication (new hostapd.conf 465 variables: ca_cert, server_cert, private_key, private_key_passwd); 466 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 467 external RADIUS server 468 * added support for reading PKCS#12 (PFX) files (as a replacement for 469 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 470 4712004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 472 * added support for Acct-{Input,Output}-Gigawords 473 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 474 * added support for RADIUS Authentication Client MIB (RFC2618) 475 * added support for RADIUS Accounting Client MIB (RFC2620) 476 * made EAP re-authentication period configurable (eap_reauth_period) 477 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 478 * fixed EAPOL state machine to stop if STA is removed during 479 eapol_sm_step(); this fixes at least one segfault triggering bug with 480 IEEE 802.11i pre-authentication 481 * added support for multiple WPA pre-shared keys (e.g., one for each 482 client MAC address or keys shared by a group of clients); 483 new hostapd.conf field wpa_psk_file for setting path to a text file 484 containing PSKs, see hostapd.wpa_psk for an example 485 * added support for multiple driver interfaces to allow hostapd to be 486 used with other drivers 487 * added wired authenticator driver interface (driver=wired in 488 hostapd.conf, see wired.conf for example configuration) 489 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 490 madwifi.conf for example configuration; Note: include files from 491 madwifi project is needed for building and a configuration file, 492 .config, needs to be created in hostapd directory with 493 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 494 build) 495 * fixed an alignment issue that could cause SHA-1 to fail on some 496 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 497 align variables) 498 * fixed RADIUS reconnection after an error in sending interim 499 accounting packets 500 * added hostapd control interface for external programs and an example 501 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 502 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 503 'hostapd_cli sta <addr>') 504 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 505 * added support for strict GTK rekeying (wpa_strict_rekey in 506 hostapd.conf) 507 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 508 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 509 IEEE 802.11F-2003) 510 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 511 note: .config needs to be created in hostapd directory with 512 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 513 build) 514 * dual-licensed hostapd (GPLv2 and BSD licenses) 515 * fixed RADIUS accounting to generate a new session id for cases where 516 a station reassociates without first being complete deauthenticated 517 * fixed STA disassociation handler to mark next timeout state to 518 deauthenticate the station, i.e., skip long wait for inactivity poll 519 and extra disassociation, if the STA disassociates without 520 deauthenticating 521 * added integrated EAP authenticator that can be used instead of 522 external RADIUS authentication server; currently, only EAP-MD5 is 523 supported, so this cannot yet be used for key distribution; the EAP 524 method interface is generic, though, so adding new EAP methods should 525 be straightforward; new hostapd.conf variables: 'eap_authenticator' 526 and 'eap_user_file'; this obsoletes "minimal authentication server" 527 ('minimal_eap' in hostapd.conf) which is now removed 528 * added support for FreeBSD and driver interface for the BSD net80211 529 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 530 .config); please note that some of the required kernel mods have not 531 yet been committed 532 5332004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 534 * fixed some accounting cases where Accounting-Start was sent when 535 IEEE 802.1X port was being deauthorized 536 5372004-06-20 - v0.2.3 538 * modified RADIUS client to re-connect the socket in case of certain 539 error codes that are generated when a network interface state is 540 changes (e.g., when IP address changes or the interface is set UP) 541 * fixed couple of cases where EAPOL state for a station was freed 542 twice causing a segfault for hostapd 543 * fixed couple of bugs in processing WPA deauthentication (freed data 544 was used) 545 5462004-05-31 - v0.2.2 547 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 548 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 549 cases where STAs dropped multicast frames as replay attacks 550 * added support for copying RADIUS Attribute 'Class' from 551 authentication messages into accounting messages 552 * send canned EAP failure if RADIUS server sends Access-Reject without 553 EAP message (previously, Supplicant was not notified in this case) 554 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 555 not start EAPOL state machines if the STA selected to use WPA-PSK) 556 5572004-05-06 - v0.2.1 558 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 559 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 560 (i.e., IEEE 802.11i/D3.0) 561 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 562 - both WPA-PSK and WPA-RADIUS/EAP are supported 563 - PMKSA caching and pre-authentication 564 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 565 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 566 rsn_preauth, rsn_preauth_interfaces 567 * fixed interim accounting to remove any pending accounting messages 568 to the STA before sending a new one 569 5702004-02-15 - v0.2.0 571 * added support for Acct-Interim-Interval: 572 - draft-ietf-radius-acct-interim-01.txt 573 - use Acct-Interim-Interval attribute from Access-Accept if local 574 'radius_acct_interim_interval' is not set 575 - allow different update intervals for each STA 576 * fixed event loop to call signal handlers only after returning from 577 the real signal handler 578 * reset sta->timeout_next after successful association to make sure 579 that the previously registered inactivity timer will not remove the 580 STA immediately (e.g., if STA deauthenticates and re-associates 581 before the timer is triggered). 582 * added new hostapd.conf variable, nas_identifier, that can be used to 583 add an optional RADIUS Attribute, NAS-Identifier, into authentication 584 and accounting messages 585 * added support for Accounting-On and Accounting-Off messages 586 * fixed accounting session handling to send Accounting-Start only once 587 per session and not to send Accounting-Stop if the session was not 588 initialized properly 589 * fixed Accounting-Stop statistics in cases where the message was 590 previously sent after the kernel entry for the STA (and/or IEEE 591 802.1X data) was removed 592 593 594Note: 595 596Older changes up to and including v0.1.0 are included in the ChangeLog 597of the Host AP driver. 598
