1ChangeLog for hostapd 2 32009-02-15 - v0.6.8 4 * increased hostapd_cli ping interval to 5 seconds and made this 5 configurable with a new command line options (-G<seconds>) 6 * driver_nl80211: use Linux socket filter to improve performance 7 * added support for external Registrars with WPS (UPnP transport) 8 92009-01-06 - v0.6.7 10 * added support for Wi-Fi Protected Setup (WPS) 11 (hostapd can now be configured to act as an integrated WPS Registrar 12 and provision credentials for WPS Enrollees using PIN and PBC 13 methods; external wireless Registrar can configure the AP, but 14 external WLAN Manager Registrars are not supported); WPS support can 15 be enabled by adding CONFIG_WPS=y into .config and setting the 16 runtime configuration variables in hostapd.conf (see WPS section in 17 the example configuration file); new hostapd_cli commands wps_pin and 18 wps_pbc are used to configure WPS negotiation; see README-WPS for 19 more details 20 * added IEEE 802.11n HT capability configuration (ht_capab) 21 * added support for generating Country IE based on nl80211 regulatory 22 information (added if ieee80211d=1 in configuration) 23 * fixed WEP authentication (both Open System and Shared Key) with 24 mac80211 25 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 26 * added support for using driver_test over UDP socket 27 * changed EAP-GPSK to use the IANA assigned EAP method type 51 28 * updated management frame protection to use IEEE 802.11w/D7.0 29 * fixed retransmission of EAP requests if no response is received 30 312008-11-23 - v0.6.6 32 * added a new configuration option, wpa_ptk_rekey, that can be used to 33 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 34 TKIP deficiencies 35 * updated OpenSSL code for EAP-FAST to use an updated version of the 36 session ticket overriding API that was included into the upstream 37 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 38 needed with that version anymore) 39 * changed channel flags configuration to read the information from 40 the driver (e.g., via driver_nl80211 when using mac80211) instead of 41 using hostapd as the source of the regulatory information (i.e., 42 information from CRDA is now used with mac80211); this allows 5 GHz 43 channels to be used with hostapd (if allowed in the current 44 regulatory domain) 45 * fixed EAP-TLS message processing for the last TLS message if it is 46 large enough to require fragmentation (e.g., if a large Session 47 Ticket data is included) 48 * fixed listen interval configuration for nl80211 drivers 49 502008-11-01 - v0.6.5 51 * added support for SHA-256 as X.509 certificate digest when using the 52 internal X.509/TLSv1 implementation 53 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 54 identity lengths) 55 * fixed internal TLSv1 implementation for abbreviated handshake (used 56 by EAP-FAST server) 57 * added support for setting VLAN ID for STAs based on local MAC ACL 58 (accept_mac_file) as an alternative for RADIUS server-based 59 configuration 60 * updated management frame protection to use IEEE 802.11w/D6.0 61 (adds a new association ping to protect against unauthenticated 62 authenticate or (re)associate request frames dropping association) 63 * added support for using SHA256-based stronger key derivation for WPA2 64 (IEEE 802.11w) 65 * added new "driver wrapper" for RADIUS-only configuration 66 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 67 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 68 is enabled in configuration 69 * changed EAP-FAST configuration to use separate fields for A-ID and 70 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 71 16-octet len binary value for better interoperability with some peer 72 implementations; eap_fast_a_id is now configured as a hex string 73 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 74 configuration (wireless-testing.git and Linux kernel releases 75 starting from 2.6.29) 76 772008-08-10 - v0.6.4 78 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 79 Identity Request if identity is already known 80 * added support for EAP Sequences in EAP-FAST Phase 2 81 * added support for EAP-TNC (Trusted Network Connect) 82 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 83 changes needed to run two methods in sequence (IF-T) and the IF-IMV 84 and IF-TNCCS interfaces from TNCS) 85 * added support for optional cryptobinding with PEAPv0 86 * added fragmentation support for EAP-TNC 87 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 88 data 89 * added support for opportunistic key caching (OKC) 90 912008-02-22 - v0.6.3 92 * fixed Reassociation Response callback processing when using internal 93 MLME (driver_{hostap,nl80211,test}.c) 94 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 95 * copy optional Proxy-State attributes into RADIUS response when acting 96 as a RADIUS authentication server 97 * fixed EAPOL state machine to handle a case in which no response is 98 received from the RADIUS authentication server; previous version 99 could have triggered a crash in some cases after a timeout 100 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 101 be used 102 * added a workaround for EAP-SIM/AKA peers that include incorrect null 103 termination in the username 104 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 105 attribute in notification messages only when using fast 106 reauthentication 107 * fixed EAP-SIM Start response processing for fast reauthentication 108 case 109 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 110 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 111 1122008-01-01 - v0.6.2 113 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 114 lengths properly to avoid potential crash caused by invalid messages 115 * added data structure for storing allocated buffers (struct wpabuf); 116 this does not affect hostapd usage, but many of the APIs changed 117 and various interfaces (e.g., EAP) is not compatible with old 118 versions 119 * added support for protecting EAP-AKA/Identity messages with 120 AT_CHECKCODE (optional feature in RFC 4187) 121 * added support for protected result indication with AT_RESULT_IND for 122 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 123 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 124 EAP server configuration; previously all four were enabled for every 125 phase 2 user, now all four are disabled by default and need to be 126 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 127 TTLS-MSCHAPV2 128 * removed old debug printing mechanism and the related 'debug' 129 parameter in the configuration file; debug verbosity is now set with 130 -d (or -dd) command line arguments 131 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 132 only shared key/password authentication is supported in this version 133 1342007-11-24 - v0.6.1 135 * added experimental, integrated TLSv1 server implementation with the 136 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 137 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 138 .config); this can be useful, e.g., if the target system does not 139 have a suitable TLS library and a minimal code size is required 140 * added support for EAP-FAST server method to the integrated EAP 141 server 142 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 143 draft (draft-ietf-emu-eap-gpsk-07.txt) 144 * added a new configuration parameter, rsn_pairwise, to allow different 145 pairwise cipher suites to be enabled for WPA and RSN/WPA2 146 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 147 either need to support this or will have to use the WPA/RSN IEs from 148 hostapd; currently, the included madwifi and bsd driver interfaces do 149 not have support for this) 150 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 151 1522007-05-28 - v0.6.0 153 * added experimental IEEE 802.11r/D6.0 support 154 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 155 * updated EAP-PSK to use the IANA-allocated EAP type 47 156 * fixed EAP-PSK bit ordering of the Flags field 157 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 158 by reading wpa_psk_file [Bug 181] 159 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 160 * fixed IPv6 connection to RADIUS accounting server 161 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 162 draft (draft-ietf-emu-eap-gpsk-04.txt) 163 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 164 entries instead of only using the same three triplets every time 165 (this does not work properly with tests using multiple clients, but 166 provides bit better triplet data for testing a single client; anyway, 167 if a better quality triplets are needed, GSM-Milenage should be used 168 instead of hardcoded triplet file) 169 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 170 in Success Request [Bug 203] 171 * added support for sending EAP-AKA Notifications in error cases 172 * updated to use IEEE 802.11w/D2.0 for management frame protection 173 (still experimental) 174 * RADIUS server: added support for processing duplicate messages 175 (retransmissions from RADIUS client) by replying with the previous 176 reply 177 1782006-11-24 - v0.5.6 179 * added support for configuring and controlling multiple BSSes per 180 radio interface (bss=<ifname> in hostapd.conf); this is only 181 available with Devicescape and test driver interfaces 182 * fixed PMKSA cache update in the end of successful RSN 183 pre-authentication 184 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 185 for each STA based on RADIUS Access-Accept attributes); this requires 186 VLAN support from the kernel driver/802.11 stack and this is 187 currently only available with Devicescape and test driver interfaces 188 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 189 and IEEE 802.1X without WEP) 190 * removed STAKey handshake since PeerKey handshake has replaced it in 191 IEEE 802.11ma and there are no known deployments of STAKey 192 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 193 draft (draft-ietf-emu-eap-gpsk-01.txt) 194 * added preliminary implementation of IEEE 802.11w/D1.0 (management 195 frame protection) 196 (Note: this requires driver support to work properly.) 197 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 198 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 199 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 200 parameters from a text file to make it possible to implement proper 201 GSM/UMTS authentication server for multiple SIM/USIM cards using 202 EAP-SIM/EAP-AKA 203 * fixed session timeout processing with drivers that do not use 204 ieee802_11.c (e.g., madwifi) 205 2062006-08-27 - v0.5.5 207 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 208 hostapd (e.g., to initialize wired network authentication based on an 209 external signal) 210 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 211 using WPA2 even if PMKSA caching is not used 212 * added -P<pid file> argument for hostapd to write the current process 213 id into a file 214 * added support for RADIUS Authentication Server MIB (RFC 2619) 215 2162006-06-20 - v0.5.4 217 * fixed nt_password_hash build [Bug 144] 218 * added PeerKey handshake implementation for IEEE 802.11e 219 direct link setup (DLS) to replace STAKey handshake 220 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 221 draft-clancy-emu-eap-shared-secret-00.txt) 222 * fixed a segmentation fault when RSN pre-authentication was completed 223 successfully [Bug 152] 224 2252006-04-27 - v0.5.3 226 * do not build nt_password_hash and hlr_auc_gw by default to avoid 227 requiring a TLS library for a successful build; these programs can be 228 build with 'make nt_password_hash' and 'make hlr_auc_gw' 229 * added a new configuration option, eapol_version, that can be used to 230 set EAPOL version to 1 (default is 2) to work around broken client 231 implementations that drop EAPOL frames which use version number 2 232 [Bug 89] 233 * added support for EAP-SAKE (no EAP method number allocated yet, so 234 this is using the same experimental type 255 as EAP-PSK) 235 * fixed EAP-MSCHAPv2 message length validation 236 2372006-03-19 - v0.5.2 238 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 239 logging was enabled, hostapd could trigger a segmentation fault in 240 vsyslog on some CPU -- C library combinations 241 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 242 program to make it easier to use for implementing real SS7 gateway; 243 eap_sim_db is not anymore used as a file name for GSM authentication 244 triplets; instead, it is path to UNIX domain socket that will be used 245 to communicate with the external gateway program (e.g., hlr_auc_gw) 246 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 247 local information (GSM authentication triplets from a text file and 248 hardcoded AKA authentication data); this can be used to test EAP-SIM 249 and EAP-AKA 250 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 251 to make it possible to test EAP-AKA with real USIM cards (this is 252 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 253 to enable this) 254 * driver_madwifi: added support for getting station RSN IE from 255 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 256 broken with earlier change (r1357) in the driver 257 * changed EAP method registration to use a dynamic list of methods 258 instead of a static list generated at build time 259 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 260 [Bug 125] 261 * added ap_max_inactivity configuration parameter 262 2632006-01-29 - v0.5.1 264 * driver_test: added better support for multiple APs and STAs by using 265 a directory with sockets that include MAC address for each device in 266 the name (test_socket=DIR:/tmp/test) 267 * added support for EAP expanded type (vendor specific EAP methods) 268 2692005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 270 * added experimental STAKey handshake implementation for IEEE 802.11e 271 direct link setup (DLS); note: this is disabled by default in both 272 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 273 and stakey=1) 274 * added support for EAP methods to use callbacks to external programs 275 by buffering a pending request and processing it after the EAP method 276 is ready to continue 277 * improved EAP-SIM database interface to allow external request to GSM 278 HLR/AuC without blocking hostapd process 279 * added support for using EAP-SIM pseudonyms and fast re-authentication 280 * added support for EAP-AKA in the integrated EAP authenticator 281 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 282 user database to allow EAP-SIM/AKA selection without extra roundtrip 283 for EAP-Nak negotiation 284 * added support for storing EAP user password as NtPasswordHash instead 285 of plaintext password when using MSCHAP or MSCHAPv2 for 286 authentication (hash:<16-octet hex value>); added nt_password_hash 287 tool for hashing password to generate NtPasswordHash 288 2892005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 290 * driver_wired: fixed EAPOL sending to optionally use PAE group address 291 as the destination instead of supplicant MAC address; this is 292 disabled by default, but should be enabled with use_pae_group_addr=1 293 in configuration file if the wired interface is used by only one 294 device at the time (common switch configuration) 295 * driver_madwifi: configure driver to use TKIP countermeasures in order 296 to get correct behavior (IEEE 802.11 association failing; previously, 297 association succeeded, but hostpad forced disassociation immediately) 298 * driver_madwifi: added support for madwifi-ng 299 3002005-10-27 - v0.4.6 301 * added support for replacing user identity from EAP with RADIUS 302 User-Name attribute from Access-Accept message, if that is included, 303 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 304 tunneled identity into accounting messages when the RADIUS server 305 does not support better way of doing this with Class attribute) 306 * driver_madwifi: fixed EAPOL packet receive for configuration where 307 ath# is part of a bridge interface 308 * added a configuration file and log analyzer script for logwatch 309 * fixed EAPOL state machine step function to process all state 310 transitions before processing new events; this resolves a race 311 condition in which EAPOL-Start message could trigger hostapd to send 312 two EAP-Response/Identity frames to the authentication server 313 3142005-09-25 - v0.4.5 315 * added client CA list to the TLS certificate request in order to make 316 it easier for the client to select which certificate to use 317 * added experimental support for EAP-PSK 318 * added support for WE-19 (hostap, madwifi) 319 3202005-08-21 - v0.4.4 321 * fixed build without CONFIG_RSN_PREAUTH 322 * fixed FreeBSD build 323 3242005-06-26 - v0.4.3 325 * fixed PMKSA caching to copy User-Name and Class attributes so that 326 RADIUS accounting gets correct information 327 * start RADIUS accounting only after successful completion of WPA 328 4-Way Handshake if WPA-PSK is used 329 * fixed PMKSA caching for the case where STA (re)associates without 330 first disassociating 331 3322005-06-12 - v0.4.2 333 * EAP-PAX is now registered as EAP type 46 334 * fixed EAP-PAX MAC calculation 335 * fixed EAP-PAX CK and ICK key derivation 336 * renamed eap_authenticator configuration variable to eap_server to 337 better match with RFC 3748 (EAP) terminology 338 * driver_test: added support for testing hostapd with wpa_supplicant 339 by using test driver interface without any kernel drivers or network 340 cards 341 3422005-05-22 - v0.4.1 343 * fixed RADIUS server initialization when only auth or acct server 344 is configured and the other one is left empty 345 * driver_madwifi: added support for RADIUS accounting 346 * driver_madwifi: added preliminary support for compiling against 'BSD' 347 branch of madwifi CVS tree 348 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 349 without disassociation 350 * added support for reading additional certificates from PKCS#12 files 351 and adding them to the certificate chain 352 * fixed RADIUS Class attribute processing to only use Access-Accept 353 packets to update Class; previously, other RADIUS authentication 354 packets could have cleared Class attribute 355 * added support for more than one Class attribute in RADIUS packets 356 * added support for verifying certificate revocation list (CRL) when 357 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 358 options 'check_crl'; CRL must be included in the ca_cert file for now 359 3602005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 361 * added support for including network information into 362 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 363 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 364 * fixed a bug which caused some RSN pre-authentication cases to use 365 freed memory and potentially crash hostapd 366 * fixed private key loading for cases where passphrase is not set 367 * added support for sending TLS alerts and aborting authentication 368 when receiving a TLS alert 369 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 370 authenticator 371 * fixed PMKSA caching (EAP authentication was not skipped correctly 372 with the new state machine changes from IEEE 802.1X draft) 373 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 374 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 375 to be added to .config to include IPv6 support); for RADIUS server, 376 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 377 in RADIUS clients file can then use IPv6 format 378 * added experimental support for EAP-PAX 379 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 380 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 381 3822005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 383 3842005-01-23 - v0.3.5 385 * added support for configuring a forced PEAP version based on the 386 Phase 1 identity 387 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 388 to terminate authentication 389 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 390 draft 391 * clear accounting data in the driver when starting a new accounting 392 session 393 * driver_madwifi: filter wireless events based on ifindex to allow more 394 than one network interface to be used 395 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 396 setting if the packet does not pass MIC verification (e.g., due to 397 incorrect PSK); previously, message 1/4 was not tried again if an 398 invalid message 2/4 was received 399 * fixed reconfiguration of RADIUS client retransmission timer when 400 adding a new message to the pending list; previously, timer was not 401 updated at this point and if there was a pending message with long 402 time for the next retry, the new message needed to wait that long for 403 its first retry, too 404 4052005-01-09 - v0.3.4 406 * added support for configuring multiple allowed EAP types for Phase 2 407 authentication (EAP-PEAP, EAP-TTLS) 408 * fixed EAPOL-Start processing to trigger WPA reauthentication 409 (previously, only EAPOL authentication was done) 410 4112005-01-02 - v0.3.3 412 * added support for EAP-PEAP in the integrated EAP authenticator 413 * added support for EAP-GTC in the integrated EAP authenticator 414 * added support for configuring list of EAP methods for Phase 1 so that 415 the integrated EAP authenticator can, e.g., use the wildcard entry 416 for EAP-TLS and EAP-PEAP 417 * added support for EAP-TTLS in the integrated EAP authenticator 418 * added support for EAP-SIM in the integrated EAP authenticator 419 * added support for using hostapd as a RADIUS authentication server 420 with the integrated EAP authenticator taking care of EAP 421 authentication (new hostapd.conf options: radius_server_clients and 422 radius_server_auth_port); this is not included in default build; use 423 CONFIG_RADIUS_SERVER=y in .config to include 424 4252004-12-19 - v0.3.2 426 * removed 'daemonize' configuration file option since it has not really 427 been used at all for more than year 428 * driver_madwifi: fixed group key setup and added get_ssid method 429 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 430 4312004-12-12 - v0.3.1 432 * added support for integrated EAP-TLS authentication (new hostapd.conf 433 variables: ca_cert, server_cert, private_key, private_key_passwd); 434 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 435 external RADIUS server 436 * added support for reading PKCS#12 (PFX) files (as a replacement for 437 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 438 4392004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 440 * added support for Acct-{Input,Output}-Gigawords 441 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 442 * added support for RADIUS Authentication Client MIB (RFC2618) 443 * added support for RADIUS Accounting Client MIB (RFC2620) 444 * made EAP re-authentication period configurable (eap_reauth_period) 445 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 446 * fixed EAPOL state machine to stop if STA is removed during 447 eapol_sm_step(); this fixes at least one segfault triggering bug with 448 IEEE 802.11i pre-authentication 449 * added support for multiple WPA pre-shared keys (e.g., one for each 450 client MAC address or keys shared by a group of clients); 451 new hostapd.conf field wpa_psk_file for setting path to a text file 452 containing PSKs, see hostapd.wpa_psk for an example 453 * added support for multiple driver interfaces to allow hostapd to be 454 used with other drivers 455 * added wired authenticator driver interface (driver=wired in 456 hostapd.conf, see wired.conf for example configuration) 457 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 458 madwifi.conf for example configuration; Note: include files from 459 madwifi project is needed for building and a configuration file, 460 .config, needs to be created in hostapd directory with 461 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 462 build) 463 * fixed an alignment issue that could cause SHA-1 to fail on some 464 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 465 align variables) 466 * fixed RADIUS reconnection after an error in sending interim 467 accounting packets 468 * added hostapd control interface for external programs and an example 469 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 470 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 471 'hostapd_cli sta <addr>') 472 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 473 * added support for strict GTK rekeying (wpa_strict_rekey in 474 hostapd.conf) 475 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 476 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 477 IEEE 802.11F-2003) 478 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 479 note: .config needs to be created in hostapd directory with 480 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 481 build) 482 * dual-licensed hostapd (GPLv2 and BSD licenses) 483 * fixed RADIUS accounting to generate a new session id for cases where 484 a station reassociates without first being complete deauthenticated 485 * fixed STA disassociation handler to mark next timeout state to 486 deauthenticate the station, i.e., skip long wait for inactivity poll 487 and extra disassociation, if the STA disassociates without 488 deauthenticating 489 * added integrated EAP authenticator that can be used instead of 490 external RADIUS authentication server; currently, only EAP-MD5 is 491 supported, so this cannot yet be used for key distribution; the EAP 492 method interface is generic, though, so adding new EAP methods should 493 be straightforward; new hostapd.conf variables: 'eap_authenticator' 494 and 'eap_user_file'; this obsoletes "minimal authentication server" 495 ('minimal_eap' in hostapd.conf) which is now removed 496 * added support for FreeBSD and driver interface for the BSD net80211 497 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 498 .config); please note that some of the required kernel mods have not 499 yet been committed 500 5012004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 502 * fixed some accounting cases where Accounting-Start was sent when 503 IEEE 802.1X port was being deauthorized 504 5052004-06-20 - v0.2.3 506 * modified RADIUS client to re-connect the socket in case of certain 507 error codes that are generated when a network interface state is 508 changes (e.g., when IP address changes or the interface is set UP) 509 * fixed couple of cases where EAPOL state for a station was freed 510 twice causing a segfault for hostapd 511 * fixed couple of bugs in processing WPA deauthentication (freed data 512 was used) 513 5142004-05-31 - v0.2.2 515 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 516 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 517 cases where STAs dropped multicast frames as replay attacks 518 * added support for copying RADIUS Attribute 'Class' from 519 authentication messages into accounting messages 520 * send canned EAP failure if RADIUS server sends Access-Reject without 521 EAP message (previously, Supplicant was not notified in this case) 522 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 523 not start EAPOL state machines if the STA selected to use WPA-PSK) 524 5252004-05-06 - v0.2.1 526 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 527 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 528 (i.e., IEEE 802.11i/D3.0) 529 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 530 - both WPA-PSK and WPA-RADIUS/EAP are supported 531 - PMKSA caching and pre-authentication 532 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 533 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 534 rsn_preauth, rsn_preauth_interfaces 535 * fixed interim accounting to remove any pending accounting messages 536 to the STA before sending a new one 537 5382004-02-15 - v0.2.0 539 * added support for Acct-Interim-Interval: 540 - draft-ietf-radius-acct-interim-01.txt 541 - use Acct-Interim-Interval attribute from Access-Accept if local 542 'radius_acct_interim_interval' is not set 543 - allow different update intervals for each STA 544 * fixed event loop to call signal handlers only after returning from 545 the real signal handler 546 * reset sta->timeout_next after successful association to make sure 547 that the previously registered inactivity timer will not remove the 548 STA immediately (e.g., if STA deauthenticates and re-associates 549 before the timer is triggered). 550 * added new hostapd.conf variable, nas_identifier, that can be used to 551 add an optional RADIUS Attribute, NAS-Identifier, into authentication 552 and accounting messages 553 * added support for Accounting-On and Accounting-Off messages 554 * fixed accounting session handling to send Accounting-Start only once 555 per session and not to send Accounting-Stop if the session was not 556 initialized properly 557 * fixed Accounting-Stop statistics in cases where the message was 558 previously sent after the kernel entry for the STA (and/or IEEE 559 802.1X data) was removed 560 561 562Note: 563 564Older changes up to and including v0.1.0 are included in the ChangeLog 565of the Host AP driver. 566
