1 ChangeLog for hostapd 2 3 2010-04-18 - v0.7.2 4 * fix WPS internal Registrar use when an external Registrar is also 5 active 6 * bsd: Cleaned up driver wrapper and added various low-level 7 configuration options 8 * TNC: fixed issues with fragmentation 9 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 10 interoperate with other implementations; may potentially breaks 11 compatibility with older wpa_supplicant/hostapd versions) 12 * cleaned up driver wrapper API for multi-BSS operations 13 * nl80211: fix multi-BSS and VLAN operations 14 * fix number of issues with IEEE 802.11r/FT; this version is not 15 backwards compatible with old versions 16 * add SA Query Request processing in AP mode (IEEE 802.11w) 17 * fix IGTK PN in group rekeying (IEEE 802.11w) 18 * fix WPS PBC session overlap detection to use correct attribute 19 * hostapd_notif_Assoc() can now be called with all IEs to simplify 20 driver wrappers 21 * work around interoperability issue with some WPS External Registrar 22 implementations 23 * nl80211: fix WPS IE update 24 * hostapd_cli: add support for action script operations (run a script 25 on hostapd events) 26 * fix DH padding with internal crypto code (mainly, for WPS) 27 * fix WPS association with both WPS IE and WPA/RSN IE present with 28 driver wrappers that use hostapd MLME (e.g., nl80211) 29 30 2010-01-16 - v0.7.1 31 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 32 is not fully backwards compatible, so out-of-tree driver wrappers 33 will need modifications 34 * cleaned up various module interfaces 35 * merge hostapd and wpa_supplicant developers' documentation into a 36 single document 37 * fixed HT Capabilities IE with nl80211 drivers 38 * moved generic AP functionality code into src/ap 39 * WPS: handle Selected Registrar as union of info from all Registrars 40 * remove obsolte Prism54.org driver wrapper 41 * added internal debugging mechanism with backtrace support and memory 42 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 43 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 44 * WPS: add support for dynamically selecting whether to provision the 45 PSK as an ASCII passphrase or PSK 46 * added support for WDS (4-address frame) mode with per-station virtual 47 interfaces (wds_sta=1 in config file; only supported with 48 driver=nl80211 for now) 49 * fixed WPS Probe Request processing to handle missing required 50 attribute 51 * fixed PKCS#12 use with OpenSSL 1.0.0 52 * detect bridge interface automatically so that bridge parameter in 53 hostapd.conf becomes optional (though, it may now be used to 54 automatically add then WLAN interface into a bridge with 55 driver=nl80211) 56 57 2009-11-21 - v0.7.0 58 * increased hostapd_cli ping interval to 5 seconds and made this 59 configurable with a new command line options (-G<seconds>) 60 * driver_nl80211: use Linux socket filter to improve performance 61 * added support for external Registrars with WPS (UPnP transport) 62 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 63 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 64 reported correctly; TX/RX packets not yet available from kernel) 65 * added support for WPS USBA out-of-band mechanism with USB Flash 66 Drives (UFD) (CONFIG_WPS_UFD=y) 67 * fixed EAPOL/EAP reauthentication when using an external RADIUS 68 authentication server 69 * fixed TNC with EAP-TTLS 70 * fixed IEEE 802.11r key derivation function to match with the standard 71 (note: this breaks interoperability with previous version) [Bug 303] 72 * fixed SHA-256 based key derivation function to match with the 73 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 74 (note: this breaks interoperability with previous version) [Bug 307] 75 * added number of code size optimizations to remove unnecessary 76 functionality from the program binary based on build configuration 77 (part of this automatic; part configurable with CONFIG_NO_* build 78 options) 79 * use shared driver wrapper files with wpa_supplicant 80 * driver_nl80211: multiple updates to provide support for new Linux 81 nl80211/mac80211 functionality 82 * updated management frame protection to use IEEE Std 802.11w-2009 83 * fixed number of small WPS issues and added workarounds to 84 interoperate with common deployed broken implementations 85 * added some IEEE 802.11n co-existance rules to disable 40 MHz channels 86 or modify primary/secondary channels if needed based on neighboring 87 networks 88 * added support for NFC out-of-band mechanism with WPS 89 * added preliminary support for IEEE 802.11r RIC processing 90 91 2009-01-06 - v0.6.7 92 * added support for Wi-Fi Protected Setup (WPS) 93 (hostapd can now be configured to act as an integrated WPS Registrar 94 and provision credentials for WPS Enrollees using PIN and PBC 95 methods; external wireless Registrar can configure the AP, but 96 external WLAN Manager Registrars are not supported); WPS support can 97 be enabled by adding CONFIG_WPS=y into .config and setting the 98 runtime configuration variables in hostapd.conf (see WPS section in 99 the example configuration file); new hostapd_cli commands wps_pin and 100 wps_pbc are used to configure WPS negotiation; see README-WPS for 101 more details 102 * added IEEE 802.11n HT capability configuration (ht_capab) 103 * added support for generating Country IE based on nl80211 regulatory 104 information (added if ieee80211d=1 in configuration) 105 * fixed WEP authentication (both Open System and Shared Key) with 106 mac80211 107 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 108 * added support for using driver_test over UDP socket 109 * changed EAP-GPSK to use the IANA assigned EAP method type 51 110 * updated management frame protection to use IEEE 802.11w/D7.0 111 * fixed retransmission of EAP requests if no response is received 112 113 2008-11-23 - v0.6.6 114 * added a new configuration option, wpa_ptk_rekey, that can be used to 115 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 116 TKIP deficiencies 117 * updated OpenSSL code for EAP-FAST to use an updated version of the 118 session ticket overriding API that was included into the upstream 119 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 120 needed with that version anymore) 121 * changed channel flags configuration to read the information from 122 the driver (e.g., via driver_nl80211 when using mac80211) instead of 123 using hostapd as the source of the regulatory information (i.e., 124 information from CRDA is now used with mac80211); this allows 5 GHz 125 channels to be used with hostapd (if allowed in the current 126 regulatory domain) 127 * fixed EAP-TLS message processing for the last TLS message if it is 128 large enough to require fragmentation (e.g., if a large Session 129 Ticket data is included) 130 * fixed listen interval configuration for nl80211 drivers 131 132 2008-11-01 - v0.6.5 133 * added support for SHA-256 as X.509 certificate digest when using the 134 internal X.509/TLSv1 implementation 135 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 136 identity lengths) 137 * fixed internal TLSv1 implementation for abbreviated handshake (used 138 by EAP-FAST server) 139 * added support for setting VLAN ID for STAs based on local MAC ACL 140 (accept_mac_file) as an alternative for RADIUS server-based 141 configuration 142 * updated management frame protection to use IEEE 802.11w/D6.0 143 (adds a new association ping to protect against unauthenticated 144 authenticate or (re)associate request frames dropping association) 145 * added support for using SHA256-based stronger key derivation for WPA2 146 (IEEE 802.11w) 147 * added new "driver wrapper" for RADIUS-only configuration 148 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 149 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 150 is enabled in configuration 151 * changed EAP-FAST configuration to use separate fields for A-ID and 152 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 153 16-octet len binary value for better interoperability with some peer 154 implementations; eap_fast_a_id is now configured as a hex string 155 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 156 configuration (wireless-testing.git and Linux kernel releases 157 starting from 2.6.29) 158 159 2008-08-10 - v0.6.4 160 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 161 Identity Request if identity is already known 162 * added support for EAP Sequences in EAP-FAST Phase 2 163 * added support for EAP-TNC (Trusted Network Connect) 164 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 165 changes needed to run two methods in sequence (IF-T) and the IF-IMV 166 and IF-TNCCS interfaces from TNCS) 167 * added support for optional cryptobinding with PEAPv0 168 * added fragmentation support for EAP-TNC 169 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 170 data 171 * added support for opportunistic key caching (OKC) 172 173 2008-02-22 - v0.6.3 174 * fixed Reassociation Response callback processing when using internal 175 MLME (driver_{hostap,nl80211,test}.c) 176 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 177 * copy optional Proxy-State attributes into RADIUS response when acting 178 as a RADIUS authentication server 179 * fixed EAPOL state machine to handle a case in which no response is 180 received from the RADIUS authentication server; previous version 181 could have triggered a crash in some cases after a timeout 182 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 183 be used 184 * added a workaround for EAP-SIM/AKA peers that include incorrect null 185 termination in the username 186 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 187 attribute in notification messages only when using fast 188 reauthentication 189 * fixed EAP-SIM Start response processing for fast reauthentication 190 case 191 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 192 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 193 194 2008-01-01 - v0.6.2 195 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 196 lengths properly to avoid potential crash caused by invalid messages 197 * added data structure for storing allocated buffers (struct wpabuf); 198 this does not affect hostapd usage, but many of the APIs changed 199 and various interfaces (e.g., EAP) is not compatible with old 200 versions 201 * added support for protecting EAP-AKA/Identity messages with 202 AT_CHECKCODE (optional feature in RFC 4187) 203 * added support for protected result indication with AT_RESULT_IND for 204 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 205 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 206 EAP server configuration; previously all four were enabled for every 207 phase 2 user, now all four are disabled by default and need to be 208 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 209 TTLS-MSCHAPV2 210 * removed old debug printing mechanism and the related 'debug' 211 parameter in the configuration file; debug verbosity is now set with 212 -d (or -dd) command line arguments 213 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 214 only shared key/password authentication is supported in this version 215 216 2007-11-24 - v0.6.1 217 * added experimental, integrated TLSv1 server implementation with the 218 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 219 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 220 .config); this can be useful, e.g., if the target system does not 221 have a suitable TLS library and a minimal code size is required 222 * added support for EAP-FAST server method to the integrated EAP 223 server 224 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 225 draft (draft-ietf-emu-eap-gpsk-07.txt) 226 * added a new configuration parameter, rsn_pairwise, to allow different 227 pairwise cipher suites to be enabled for WPA and RSN/WPA2 228 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 229 either need to support this or will have to use the WPA/RSN IEs from 230 hostapd; currently, the included madwifi and bsd driver interfaces do 231 not have support for this) 232 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 233 234 2007-05-28 - v0.6.0 235 * added experimental IEEE 802.11r/D6.0 support 236 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 237 * updated EAP-PSK to use the IANA-allocated EAP type 47 238 * fixed EAP-PSK bit ordering of the Flags field 239 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 240 by reading wpa_psk_file [Bug 181] 241 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 242 * fixed IPv6 connection to RADIUS accounting server 243 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 244 draft (draft-ietf-emu-eap-gpsk-04.txt) 245 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 246 entries instead of only using the same three triplets every time 247 (this does not work properly with tests using multiple clients, but 248 provides bit better triplet data for testing a single client; anyway, 249 if a better quality triplets are needed, GSM-Milenage should be used 250 instead of hardcoded triplet file) 251 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 252 in Success Request [Bug 203] 253 * added support for sending EAP-AKA Notifications in error cases 254 * updated to use IEEE 802.11w/D2.0 for management frame protection 255 (still experimental) 256 * RADIUS server: added support for processing duplicate messages 257 (retransmissions from RADIUS client) by replying with the previous 258 reply 259 260 2006-11-24 - v0.5.6 261 * added support for configuring and controlling multiple BSSes per 262 radio interface (bss=<ifname> in hostapd.conf); this is only 263 available with Devicescape and test driver interfaces 264 * fixed PMKSA cache update in the end of successful RSN 265 pre-authentication 266 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 267 for each STA based on RADIUS Access-Accept attributes); this requires 268 VLAN support from the kernel driver/802.11 stack and this is 269 currently only available with Devicescape and test driver interfaces 270 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 271 and IEEE 802.1X without WEP) 272 * removed STAKey handshake since PeerKey handshake has replaced it in 273 IEEE 802.11ma and there are no known deployments of STAKey 274 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 275 draft (draft-ietf-emu-eap-gpsk-01.txt) 276 * added preliminary implementation of IEEE 802.11w/D1.0 (management 277 frame protection) 278 (Note: this requires driver support to work properly.) 279 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 280 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 281 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 282 parameters from a text file to make it possible to implement proper 283 GSM/UMTS authentication server for multiple SIM/USIM cards using 284 EAP-SIM/EAP-AKA 285 * fixed session timeout processing with drivers that do not use 286 ieee802_11.c (e.g., madwifi) 287 288 2006-08-27 - v0.5.5 289 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 290 hostapd (e.g., to initialize wired network authentication based on an 291 external signal) 292 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 293 using WPA2 even if PMKSA caching is not used 294 * added -P<pid file> argument for hostapd to write the current process 295 id into a file 296 * added support for RADIUS Authentication Server MIB (RFC 2619) 297 298 2006-06-20 - v0.5.4 299 * fixed nt_password_hash build [Bug 144] 300 * added PeerKey handshake implementation for IEEE 802.11e 301 direct link setup (DLS) to replace STAKey handshake 302 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 303 draft-clancy-emu-eap-shared-secret-00.txt) 304 * fixed a segmentation fault when RSN pre-authentication was completed 305 successfully [Bug 152] 306 307 2006-04-27 - v0.5.3 308 * do not build nt_password_hash and hlr_auc_gw by default to avoid 309 requiring a TLS library for a successful build; these programs can be 310 build with 'make nt_password_hash' and 'make hlr_auc_gw' 311 * added a new configuration option, eapol_version, that can be used to 312 set EAPOL version to 1 (default is 2) to work around broken client 313 implementations that drop EAPOL frames which use version number 2 314 [Bug 89] 315 * added support for EAP-SAKE (no EAP method number allocated yet, so 316 this is using the same experimental type 255 as EAP-PSK) 317 * fixed EAP-MSCHAPv2 message length validation 318 319 2006-03-19 - v0.5.2 320 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 321 logging was enabled, hostapd could trigger a segmentation fault in 322 vsyslog on some CPU -- C library combinations 323 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 324 program to make it easier to use for implementing real SS7 gateway; 325 eap_sim_db is not anymore used as a file name for GSM authentication 326 triplets; instead, it is path to UNIX domain socket that will be used 327 to communicate with the external gateway program (e.g., hlr_auc_gw) 328 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 329 local information (GSM authentication triplets from a text file and 330 hardcoded AKA authentication data); this can be used to test EAP-SIM 331 and EAP-AKA 332 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 333 to make it possible to test EAP-AKA with real USIM cards (this is 334 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 335 to enable this) 336 * driver_madwifi: added support for getting station RSN IE from 337 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 338 broken with earlier change (r1357) in the driver 339 * changed EAP method registration to use a dynamic list of methods 340 instead of a static list generated at build time 341 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 342 [Bug 125] 343 * added ap_max_inactivity configuration parameter 344 345 2006-01-29 - v0.5.1 346 * driver_test: added better support for multiple APs and STAs by using 347 a directory with sockets that include MAC address for each device in 348 the name (test_socket=DIR:/tmp/test) 349 * added support for EAP expanded type (vendor specific EAP methods) 350 351 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 352 * added experimental STAKey handshake implementation for IEEE 802.11e 353 direct link setup (DLS); note: this is disabled by default in both 354 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 355 and stakey=1) 356 * added support for EAP methods to use callbacks to external programs 357 by buffering a pending request and processing it after the EAP method 358 is ready to continue 359 * improved EAP-SIM database interface to allow external request to GSM 360 HLR/AuC without blocking hostapd process 361 * added support for using EAP-SIM pseudonyms and fast re-authentication 362 * added support for EAP-AKA in the integrated EAP authenticator 363 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 364 user database to allow EAP-SIM/AKA selection without extra roundtrip 365 for EAP-Nak negotiation 366 * added support for storing EAP user password as NtPasswordHash instead 367 of plaintext password when using MSCHAP or MSCHAPv2 for 368 authentication (hash:<16-octet hex value>); added nt_password_hash 369 tool for hashing password to generate NtPasswordHash 370 371 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 372 * driver_wired: fixed EAPOL sending to optionally use PAE group address 373 as the destination instead of supplicant MAC address; this is 374 disabled by default, but should be enabled with use_pae_group_addr=1 375 in configuration file if the wired interface is used by only one 376 device at the time (common switch configuration) 377 * driver_madwifi: configure driver to use TKIP countermeasures in order 378 to get correct behavior (IEEE 802.11 association failing; previously, 379 association succeeded, but hostpad forced disassociation immediately) 380 * driver_madwifi: added support for madwifi-ng 381 382 2005-10-27 - v0.4.6 383 * added support for replacing user identity from EAP with RADIUS 384 User-Name attribute from Access-Accept message, if that is included, 385 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 386 tunneled identity into accounting messages when the RADIUS server 387 does not support better way of doing this with Class attribute) 388 * driver_madwifi: fixed EAPOL packet receive for configuration where 389 ath# is part of a bridge interface 390 * added a configuration file and log analyzer script for logwatch 391 * fixed EAPOL state machine step function to process all state 392 transitions before processing new events; this resolves a race 393 condition in which EAPOL-Start message could trigger hostapd to send 394 two EAP-Response/Identity frames to the authentication server 395 396 2005-09-25 - v0.4.5 397 * added client CA list to the TLS certificate request in order to make 398 it easier for the client to select which certificate to use 399 * added experimental support for EAP-PSK 400 * added support for WE-19 (hostap, madwifi) 401 402 2005-08-21 - v0.4.4 403 * fixed build without CONFIG_RSN_PREAUTH 404 * fixed FreeBSD build 405 406 2005-06-26 - v0.4.3 407 * fixed PMKSA caching to copy User-Name and Class attributes so that 408 RADIUS accounting gets correct information 409 * start RADIUS accounting only after successful completion of WPA 410 4-Way Handshake if WPA-PSK is used 411 * fixed PMKSA caching for the case where STA (re)associates without 412 first disassociating 413 414 2005-06-12 - v0.4.2 415 * EAP-PAX is now registered as EAP type 46 416 * fixed EAP-PAX MAC calculation 417 * fixed EAP-PAX CK and ICK key derivation 418 * renamed eap_authenticator configuration variable to eap_server to 419 better match with RFC 3748 (EAP) terminology 420 * driver_test: added support for testing hostapd with wpa_supplicant 421 by using test driver interface without any kernel drivers or network 422 cards 423 424 2005-05-22 - v0.4.1 425 * fixed RADIUS server initialization when only auth or acct server 426 is configured and the other one is left empty 427 * driver_madwifi: added support for RADIUS accounting 428 * driver_madwifi: added preliminary support for compiling against 'BSD' 429 branch of madwifi CVS tree 430 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 431 without disassociation 432 * added support for reading additional certificates from PKCS#12 files 433 and adding them to the certificate chain 434 * fixed RADIUS Class attribute processing to only use Access-Accept 435 packets to update Class; previously, other RADIUS authentication 436 packets could have cleared Class attribute 437 * added support for more than one Class attribute in RADIUS packets 438 * added support for verifying certificate revocation list (CRL) when 439 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 440 options 'check_crl'; CRL must be included in the ca_cert file for now 441 442 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 443 * added support for including network information into 444 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 445 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 446 * fixed a bug which caused some RSN pre-authentication cases to use 447 freed memory and potentially crash hostapd 448 * fixed private key loading for cases where passphrase is not set 449 * added support for sending TLS alerts and aborting authentication 450 when receiving a TLS alert 451 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 452 authenticator 453 * fixed PMKSA caching (EAP authentication was not skipped correctly 454 with the new state machine changes from IEEE 802.1X draft) 455 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 456 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 457 to be added to .config to include IPv6 support); for RADIUS server, 458 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 459 in RADIUS clients file can then use IPv6 format 460 * added experimental support for EAP-PAX 461 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 462 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 463 464 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 465 466 2005-01-23 - v0.3.5 467 * added support for configuring a forced PEAP version based on the 468 Phase 1 identity 469 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 470 to terminate authentication 471 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 472 draft 473 * clear accounting data in the driver when starting a new accounting 474 session 475 * driver_madwifi: filter wireless events based on ifindex to allow more 476 than one network interface to be used 477 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 478 setting if the packet does not pass MIC verification (e.g., due to 479 incorrect PSK); previously, message 1/4 was not tried again if an 480 invalid message 2/4 was received 481 * fixed reconfiguration of RADIUS client retransmission timer when 482 adding a new message to the pending list; previously, timer was not 483 updated at this point and if there was a pending message with long 484 time for the next retry, the new message needed to wait that long for 485 its first retry, too 486 487 2005-01-09 - v0.3.4 488 * added support for configuring multiple allowed EAP types for Phase 2 489 authentication (EAP-PEAP, EAP-TTLS) 490 * fixed EAPOL-Start processing to trigger WPA reauthentication 491 (previously, only EAPOL authentication was done) 492 493 2005-01-02 - v0.3.3 494 * added support for EAP-PEAP in the integrated EAP authenticator 495 * added support for EAP-GTC in the integrated EAP authenticator 496 * added support for configuring list of EAP methods for Phase 1 so that 497 the integrated EAP authenticator can, e.g., use the wildcard entry 498 for EAP-TLS and EAP-PEAP 499 * added support for EAP-TTLS in the integrated EAP authenticator 500 * added support for EAP-SIM in the integrated EAP authenticator 501 * added support for using hostapd as a RADIUS authentication server 502 with the integrated EAP authenticator taking care of EAP 503 authentication (new hostapd.conf options: radius_server_clients and 504 radius_server_auth_port); this is not included in default build; use 505 CONFIG_RADIUS_SERVER=y in .config to include 506 507 2004-12-19 - v0.3.2 508 * removed 'daemonize' configuration file option since it has not really 509 been used at all for more than year 510 * driver_madwifi: fixed group key setup and added get_ssid method 511 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 512 513 2004-12-12 - v0.3.1 514 * added support for integrated EAP-TLS authentication (new hostapd.conf 515 variables: ca_cert, server_cert, private_key, private_key_passwd); 516 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 517 external RADIUS server 518 * added support for reading PKCS#12 (PFX) files (as a replacement for 519 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 520 521 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 522 * added support for Acct-{Input,Output}-Gigawords 523 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 524 * added support for RADIUS Authentication Client MIB (RFC2618) 525 * added support for RADIUS Accounting Client MIB (RFC2620) 526 * made EAP re-authentication period configurable (eap_reauth_period) 527 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 528 * fixed EAPOL state machine to stop if STA is removed during 529 eapol_sm_step(); this fixes at least one segfault triggering bug with 530 IEEE 802.11i pre-authentication 531 * added support for multiple WPA pre-shared keys (e.g., one for each 532 client MAC address or keys shared by a group of clients); 533 new hostapd.conf field wpa_psk_file for setting path to a text file 534 containing PSKs, see hostapd.wpa_psk for an example 535 * added support for multiple driver interfaces to allow hostapd to be 536 used with other drivers 537 * added wired authenticator driver interface (driver=wired in 538 hostapd.conf, see wired.conf for example configuration) 539 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 540 madwifi.conf for example configuration; Note: include files from 541 madwifi project is needed for building and a configuration file, 542 .config, needs to be created in hostapd directory with 543 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 544 build) 545 * fixed an alignment issue that could cause SHA-1 to fail on some 546 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 547 align variables) 548 * fixed RADIUS reconnection after an error in sending interim 549 accounting packets 550 * added hostapd control interface for external programs and an example 551 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 552 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 553 'hostapd_cli sta <addr>') 554 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 555 * added support for strict GTK rekeying (wpa_strict_rekey in 556 hostapd.conf) 557 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 558 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 559 IEEE 802.11F-2003) 560 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 561 note: .config needs to be created in hostapd directory with 562 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 563 build) 564 * dual-licensed hostapd (GPLv2 and BSD licenses) 565 * fixed RADIUS accounting to generate a new session id for cases where 566 a station reassociates without first being complete deauthenticated 567 * fixed STA disassociation handler to mark next timeout state to 568 deauthenticate the station, i.e., skip long wait for inactivity poll 569 and extra disassociation, if the STA disassociates without 570 deauthenticating 571 * added integrated EAP authenticator that can be used instead of 572 external RADIUS authentication server; currently, only EAP-MD5 is 573 supported, so this cannot yet be used for key distribution; the EAP 574 method interface is generic, though, so adding new EAP methods should 575 be straightforward; new hostapd.conf variables: 'eap_authenticator' 576 and 'eap_user_file'; this obsoletes "minimal authentication server" 577 ('minimal_eap' in hostapd.conf) which is now removed 578 * added support for FreeBSD and driver interface for the BSD net80211 579 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 580 .config); please note that some of the required kernel mods have not 581 yet been committed 582 583 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 584 * fixed some accounting cases where Accounting-Start was sent when 585 IEEE 802.1X port was being deauthorized 586 587 2004-06-20 - v0.2.3 588 * modified RADIUS client to re-connect the socket in case of certain 589 error codes that are generated when a network interface state is 590 changes (e.g., when IP address changes or the interface is set UP) 591 * fixed couple of cases where EAPOL state for a station was freed 592 twice causing a segfault for hostapd 593 * fixed couple of bugs in processing WPA deauthentication (freed data 594 was used) 595 596 2004-05-31 - v0.2.2 597 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 598 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 599 cases where STAs dropped multicast frames as replay attacks 600 * added support for copying RADIUS Attribute 'Class' from 601 authentication messages into accounting messages 602 * send canned EAP failure if RADIUS server sends Access-Reject without 603 EAP message (previously, Supplicant was not notified in this case) 604 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 605 not start EAPOL state machines if the STA selected to use WPA-PSK) 606 607 2004-05-06 - v0.2.1 608 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 609 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 610 (i.e., IEEE 802.11i/D3.0) 611 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 612 - both WPA-PSK and WPA-RADIUS/EAP are supported 613 - PMKSA caching and pre-authentication 614 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 615 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 616 rsn_preauth, rsn_preauth_interfaces 617 * fixed interim accounting to remove any pending accounting messages 618 to the STA before sending a new one 619 620 2004-02-15 - v0.2.0 621 * added support for Acct-Interim-Interval: 622 - draft-ietf-radius-acct-interim-01.txt 623 - use Acct-Interim-Interval attribute from Access-Accept if local 624 'radius_acct_interim_interval' is not set 625 - allow different update intervals for each STA 626 * fixed event loop to call signal handlers only after returning from 627 the real signal handler 628 * reset sta->timeout_next after successful association to make sure 629 that the previously registered inactivity timer will not remove the 630 STA immediately (e.g., if STA deauthenticates and re-associates 631 before the timer is triggered). 632 * added new hostapd.conf variable, nas_identifier, that can be used to 633 add an optional RADIUS Attribute, NAS-Identifier, into authentication 634 and accounting messages 635 * added support for Accounting-On and Accounting-Off messages 636 * fixed accounting session handling to send Accounting-Start only once 637 per session and not to send Accounting-Stop if the session was not 638 initialized properly 639 * fixed Accounting-Stop statistics in cases where the message was 640 previously sent after the kernel entry for the STA (and/or IEEE 641 802.1X data) was removed 642 643 644 Note: 645 646 Older changes up to and including v0.1.0 are included in the ChangeLog 647 of the Host AP driver. 648
