1ChangeLog for hostapd 2 32010-09-07 - v0.7.3 4 * fixed re-association after WPS not initializing WPA state machine in 5 some cases 6 * fixed WPS IE update on reconfiguration 7 * fixed WPS code not to proxy Probe Request frames for foreign SSIDs 8 * added WPS workaround for open networks and some known interop issues 9 * fixed WPS Diffie-Hellman derivation to use correct public key length 10 * fixed FT RRB messages on big endian CPUs 11 * changed WPS protection for brute force AP PIN attacks to disable AP 12 PIN only temporarily (but with increasing time) to avoid usability 13 issues on Label-only devices 14 * added wps_ap_pin command for more secure handling of AP PIN 15 operations (e.g., to generate a random AP PIN and only use it for 16 short amount of time) 17 * fixed HT STBC negotiation 18 192010-04-18 - v0.7.2 20 * fix WPS internal Registrar use when an external Registrar is also 21 active 22 * bsd: Cleaned up driver wrapper and added various low-level 23 configuration options 24 * TNC: fixed issues with fragmentation 25 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 26 interoperate with other implementations; may potentially breaks 27 compatibility with older wpa_supplicant/hostapd versions) 28 * cleaned up driver wrapper API for multi-BSS operations 29 * nl80211: fix multi-BSS and VLAN operations 30 * fix number of issues with IEEE 802.11r/FT; this version is not 31 backwards compatible with old versions 32 * add SA Query Request processing in AP mode (IEEE 802.11w) 33 * fix IGTK PN in group rekeying (IEEE 802.11w) 34 * fix WPS PBC session overlap detection to use correct attribute 35 * hostapd_notif_Assoc() can now be called with all IEs to simplify 36 driver wrappers 37 * work around interoperability issue with some WPS External Registrar 38 implementations 39 * nl80211: fix WPS IE update 40 * hostapd_cli: add support for action script operations (run a script 41 on hostapd events) 42 * fix DH padding with internal crypto code (mainly, for WPS) 43 * fix WPS association with both WPS IE and WPA/RSN IE present with 44 driver wrappers that use hostapd MLME (e.g., nl80211) 45 462010-01-16 - v0.7.1 47 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 48 is not fully backwards compatible, so out-of-tree driver wrappers 49 will need modifications 50 * cleaned up various module interfaces 51 * merge hostapd and wpa_supplicant developers' documentation into a 52 single document 53 * fixed HT Capabilities IE with nl80211 drivers 54 * moved generic AP functionality code into src/ap 55 * WPS: handle Selected Registrar as union of info from all Registrars 56 * remove obsolte Prism54.org driver wrapper 57 * added internal debugging mechanism with backtrace support and memory 58 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 59 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 60 * WPS: add support for dynamically selecting whether to provision the 61 PSK as an ASCII passphrase or PSK 62 * added support for WDS (4-address frame) mode with per-station virtual 63 interfaces (wds_sta=1 in config file; only supported with 64 driver=nl80211 for now) 65 * fixed WPS Probe Request processing to handle missing required 66 attribute 67 * fixed PKCS#12 use with OpenSSL 1.0.0 68 * detect bridge interface automatically so that bridge parameter in 69 hostapd.conf becomes optional (though, it may now be used to 70 automatically add then WLAN interface into a bridge with 71 driver=nl80211) 72 732009-11-21 - v0.7.0 74 * increased hostapd_cli ping interval to 5 seconds and made this 75 configurable with a new command line options (-G<seconds>) 76 * driver_nl80211: use Linux socket filter to improve performance 77 * added support for external Registrars with WPS (UPnP transport) 78 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 79 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 80 reported correctly; TX/RX packets not yet available from kernel) 81 * added support for WPS USBA out-of-band mechanism with USB Flash 82 Drives (UFD) (CONFIG_WPS_UFD=y) 83 * fixed EAPOL/EAP reauthentication when using an external RADIUS 84 authentication server 85 * fixed TNC with EAP-TTLS 86 * fixed IEEE 802.11r key derivation function to match with the standard 87 (note: this breaks interoperability with previous version) [Bug 303] 88 * fixed SHA-256 based key derivation function to match with the 89 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 90 (note: this breaks interoperability with previous version) [Bug 307] 91 * added number of code size optimizations to remove unnecessary 92 functionality from the program binary based on build configuration 93 (part of this automatic; part configurable with CONFIG_NO_* build 94 options) 95 * use shared driver wrapper files with wpa_supplicant 96 * driver_nl80211: multiple updates to provide support for new Linux 97 nl80211/mac80211 functionality 98 * updated management frame protection to use IEEE Std 802.11w-2009 99 * fixed number of small WPS issues and added workarounds to 100 interoperate with common deployed broken implementations 101 * added some IEEE 802.11n co-existance rules to disable 40 MHz channels 102 or modify primary/secondary channels if needed based on neighboring 103 networks 104 * added support for NFC out-of-band mechanism with WPS 105 * added preliminary support for IEEE 802.11r RIC processing 106 1072009-01-06 - v0.6.7 108 * added support for Wi-Fi Protected Setup (WPS) 109 (hostapd can now be configured to act as an integrated WPS Registrar 110 and provision credentials for WPS Enrollees using PIN and PBC 111 methods; external wireless Registrar can configure the AP, but 112 external WLAN Manager Registrars are not supported); WPS support can 113 be enabled by adding CONFIG_WPS=y into .config and setting the 114 runtime configuration variables in hostapd.conf (see WPS section in 115 the example configuration file); new hostapd_cli commands wps_pin and 116 wps_pbc are used to configure WPS negotiation; see README-WPS for 117 more details 118 * added IEEE 802.11n HT capability configuration (ht_capab) 119 * added support for generating Country IE based on nl80211 regulatory 120 information (added if ieee80211d=1 in configuration) 121 * fixed WEP authentication (both Open System and Shared Key) with 122 mac80211 123 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 124 * added support for using driver_test over UDP socket 125 * changed EAP-GPSK to use the IANA assigned EAP method type 51 126 * updated management frame protection to use IEEE 802.11w/D7.0 127 * fixed retransmission of EAP requests if no response is received 128 1292008-11-23 - v0.6.6 130 * added a new configuration option, wpa_ptk_rekey, that can be used to 131 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 132 TKIP deficiencies 133 * updated OpenSSL code for EAP-FAST to use an updated version of the 134 session ticket overriding API that was included into the upstream 135 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 136 needed with that version anymore) 137 * changed channel flags configuration to read the information from 138 the driver (e.g., via driver_nl80211 when using mac80211) instead of 139 using hostapd as the source of the regulatory information (i.e., 140 information from CRDA is now used with mac80211); this allows 5 GHz 141 channels to be used with hostapd (if allowed in the current 142 regulatory domain) 143 * fixed EAP-TLS message processing for the last TLS message if it is 144 large enough to require fragmentation (e.g., if a large Session 145 Ticket data is included) 146 * fixed listen interval configuration for nl80211 drivers 147 1482008-11-01 - v0.6.5 149 * added support for SHA-256 as X.509 certificate digest when using the 150 internal X.509/TLSv1 implementation 151 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 152 identity lengths) 153 * fixed internal TLSv1 implementation for abbreviated handshake (used 154 by EAP-FAST server) 155 * added support for setting VLAN ID for STAs based on local MAC ACL 156 (accept_mac_file) as an alternative for RADIUS server-based 157 configuration 158 * updated management frame protection to use IEEE 802.11w/D6.0 159 (adds a new association ping to protect against unauthenticated 160 authenticate or (re)associate request frames dropping association) 161 * added support for using SHA256-based stronger key derivation for WPA2 162 (IEEE 802.11w) 163 * added new "driver wrapper" for RADIUS-only configuration 164 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 165 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 166 is enabled in configuration 167 * changed EAP-FAST configuration to use separate fields for A-ID and 168 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 169 16-octet len binary value for better interoperability with some peer 170 implementations; eap_fast_a_id is now configured as a hex string 171 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 172 configuration (wireless-testing.git and Linux kernel releases 173 starting from 2.6.29) 174 1752008-08-10 - v0.6.4 176 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 177 Identity Request if identity is already known 178 * added support for EAP Sequences in EAP-FAST Phase 2 179 * added support for EAP-TNC (Trusted Network Connect) 180 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 181 changes needed to run two methods in sequence (IF-T) and the IF-IMV 182 and IF-TNCCS interfaces from TNCS) 183 * added support for optional cryptobinding with PEAPv0 184 * added fragmentation support for EAP-TNC 185 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 186 data 187 * added support for opportunistic key caching (OKC) 188 1892008-02-22 - v0.6.3 190 * fixed Reassociation Response callback processing when using internal 191 MLME (driver_{hostap,nl80211,test}.c) 192 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 193 * copy optional Proxy-State attributes into RADIUS response when acting 194 as a RADIUS authentication server 195 * fixed EAPOL state machine to handle a case in which no response is 196 received from the RADIUS authentication server; previous version 197 could have triggered a crash in some cases after a timeout 198 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 199 be used 200 * added a workaround for EAP-SIM/AKA peers that include incorrect null 201 termination in the username 202 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 203 attribute in notification messages only when using fast 204 reauthentication 205 * fixed EAP-SIM Start response processing for fast reauthentication 206 case 207 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 208 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 209 2102008-01-01 - v0.6.2 211 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 212 lengths properly to avoid potential crash caused by invalid messages 213 * added data structure for storing allocated buffers (struct wpabuf); 214 this does not affect hostapd usage, but many of the APIs changed 215 and various interfaces (e.g., EAP) is not compatible with old 216 versions 217 * added support for protecting EAP-AKA/Identity messages with 218 AT_CHECKCODE (optional feature in RFC 4187) 219 * added support for protected result indication with AT_RESULT_IND for 220 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 221 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 222 EAP server configuration; previously all four were enabled for every 223 phase 2 user, now all four are disabled by default and need to be 224 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 225 TTLS-MSCHAPV2 226 * removed old debug printing mechanism and the related 'debug' 227 parameter in the configuration file; debug verbosity is now set with 228 -d (or -dd) command line arguments 229 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 230 only shared key/password authentication is supported in this version 231 2322007-11-24 - v0.6.1 233 * added experimental, integrated TLSv1 server implementation with the 234 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 235 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 236 .config); this can be useful, e.g., if the target system does not 237 have a suitable TLS library and a minimal code size is required 238 * added support for EAP-FAST server method to the integrated EAP 239 server 240 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 241 draft (draft-ietf-emu-eap-gpsk-07.txt) 242 * added a new configuration parameter, rsn_pairwise, to allow different 243 pairwise cipher suites to be enabled for WPA and RSN/WPA2 244 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 245 either need to support this or will have to use the WPA/RSN IEs from 246 hostapd; currently, the included madwifi and bsd driver interfaces do 247 not have support for this) 248 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 249 2502007-05-28 - v0.6.0 251 * added experimental IEEE 802.11r/D6.0 support 252 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 253 * updated EAP-PSK to use the IANA-allocated EAP type 47 254 * fixed EAP-PSK bit ordering of the Flags field 255 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 256 by reading wpa_psk_file [Bug 181] 257 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 258 * fixed IPv6 connection to RADIUS accounting server 259 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 260 draft (draft-ietf-emu-eap-gpsk-04.txt) 261 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 262 entries instead of only using the same three triplets every time 263 (this does not work properly with tests using multiple clients, but 264 provides bit better triplet data for testing a single client; anyway, 265 if a better quality triplets are needed, GSM-Milenage should be used 266 instead of hardcoded triplet file) 267 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 268 in Success Request [Bug 203] 269 * added support for sending EAP-AKA Notifications in error cases 270 * updated to use IEEE 802.11w/D2.0 for management frame protection 271 (still experimental) 272 * RADIUS server: added support for processing duplicate messages 273 (retransmissions from RADIUS client) by replying with the previous 274 reply 275 2762006-11-24 - v0.5.6 277 * added support for configuring and controlling multiple BSSes per 278 radio interface (bss=<ifname> in hostapd.conf); this is only 279 available with Devicescape and test driver interfaces 280 * fixed PMKSA cache update in the end of successful RSN 281 pre-authentication 282 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 283 for each STA based on RADIUS Access-Accept attributes); this requires 284 VLAN support from the kernel driver/802.11 stack and this is 285 currently only available with Devicescape and test driver interfaces 286 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 287 and IEEE 802.1X without WEP) 288 * removed STAKey handshake since PeerKey handshake has replaced it in 289 IEEE 802.11ma and there are no known deployments of STAKey 290 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 291 draft (draft-ietf-emu-eap-gpsk-01.txt) 292 * added preliminary implementation of IEEE 802.11w/D1.0 (management 293 frame protection) 294 (Note: this requires driver support to work properly.) 295 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 296 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 297 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 298 parameters from a text file to make it possible to implement proper 299 GSM/UMTS authentication server for multiple SIM/USIM cards using 300 EAP-SIM/EAP-AKA 301 * fixed session timeout processing with drivers that do not use 302 ieee802_11.c (e.g., madwifi) 303 3042006-08-27 - v0.5.5 305 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 306 hostapd (e.g., to initialize wired network authentication based on an 307 external signal) 308 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 309 using WPA2 even if PMKSA caching is not used 310 * added -P<pid file> argument for hostapd to write the current process 311 id into a file 312 * added support for RADIUS Authentication Server MIB (RFC 2619) 313 3142006-06-20 - v0.5.4 315 * fixed nt_password_hash build [Bug 144] 316 * added PeerKey handshake implementation for IEEE 802.11e 317 direct link setup (DLS) to replace STAKey handshake 318 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 319 draft-clancy-emu-eap-shared-secret-00.txt) 320 * fixed a segmentation fault when RSN pre-authentication was completed 321 successfully [Bug 152] 322 3232006-04-27 - v0.5.3 324 * do not build nt_password_hash and hlr_auc_gw by default to avoid 325 requiring a TLS library for a successful build; these programs can be 326 build with 'make nt_password_hash' and 'make hlr_auc_gw' 327 * added a new configuration option, eapol_version, that can be used to 328 set EAPOL version to 1 (default is 2) to work around broken client 329 implementations that drop EAPOL frames which use version number 2 330 [Bug 89] 331 * added support for EAP-SAKE (no EAP method number allocated yet, so 332 this is using the same experimental type 255 as EAP-PSK) 333 * fixed EAP-MSCHAPv2 message length validation 334 3352006-03-19 - v0.5.2 336 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 337 logging was enabled, hostapd could trigger a segmentation fault in 338 vsyslog on some CPU -- C library combinations 339 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 340 program to make it easier to use for implementing real SS7 gateway; 341 eap_sim_db is not anymore used as a file name for GSM authentication 342 triplets; instead, it is path to UNIX domain socket that will be used 343 to communicate with the external gateway program (e.g., hlr_auc_gw) 344 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 345 local information (GSM authentication triplets from a text file and 346 hardcoded AKA authentication data); this can be used to test EAP-SIM 347 and EAP-AKA 348 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 349 to make it possible to test EAP-AKA with real USIM cards (this is 350 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 351 to enable this) 352 * driver_madwifi: added support for getting station RSN IE from 353 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 354 broken with earlier change (r1357) in the driver 355 * changed EAP method registration to use a dynamic list of methods 356 instead of a static list generated at build time 357 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 358 [Bug 125] 359 * added ap_max_inactivity configuration parameter 360 3612006-01-29 - v0.5.1 362 * driver_test: added better support for multiple APs and STAs by using 363 a directory with sockets that include MAC address for each device in 364 the name (test_socket=DIR:/tmp/test) 365 * added support for EAP expanded type (vendor specific EAP methods) 366 3672005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 368 * added experimental STAKey handshake implementation for IEEE 802.11e 369 direct link setup (DLS); note: this is disabled by default in both 370 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 371 and stakey=1) 372 * added support for EAP methods to use callbacks to external programs 373 by buffering a pending request and processing it after the EAP method 374 is ready to continue 375 * improved EAP-SIM database interface to allow external request to GSM 376 HLR/AuC without blocking hostapd process 377 * added support for using EAP-SIM pseudonyms and fast re-authentication 378 * added support for EAP-AKA in the integrated EAP authenticator 379 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 380 user database to allow EAP-SIM/AKA selection without extra roundtrip 381 for EAP-Nak negotiation 382 * added support for storing EAP user password as NtPasswordHash instead 383 of plaintext password when using MSCHAP or MSCHAPv2 for 384 authentication (hash:<16-octet hex value>); added nt_password_hash 385 tool for hashing password to generate NtPasswordHash 386 3872005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 388 * driver_wired: fixed EAPOL sending to optionally use PAE group address 389 as the destination instead of supplicant MAC address; this is 390 disabled by default, but should be enabled with use_pae_group_addr=1 391 in configuration file if the wired interface is used by only one 392 device at the time (common switch configuration) 393 * driver_madwifi: configure driver to use TKIP countermeasures in order 394 to get correct behavior (IEEE 802.11 association failing; previously, 395 association succeeded, but hostpad forced disassociation immediately) 396 * driver_madwifi: added support for madwifi-ng 397 3982005-10-27 - v0.4.6 399 * added support for replacing user identity from EAP with RADIUS 400 User-Name attribute from Access-Accept message, if that is included, 401 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 402 tunneled identity into accounting messages when the RADIUS server 403 does not support better way of doing this with Class attribute) 404 * driver_madwifi: fixed EAPOL packet receive for configuration where 405 ath# is part of a bridge interface 406 * added a configuration file and log analyzer script for logwatch 407 * fixed EAPOL state machine step function to process all state 408 transitions before processing new events; this resolves a race 409 condition in which EAPOL-Start message could trigger hostapd to send 410 two EAP-Response/Identity frames to the authentication server 411 4122005-09-25 - v0.4.5 413 * added client CA list to the TLS certificate request in order to make 414 it easier for the client to select which certificate to use 415 * added experimental support for EAP-PSK 416 * added support for WE-19 (hostap, madwifi) 417 4182005-08-21 - v0.4.4 419 * fixed build without CONFIG_RSN_PREAUTH 420 * fixed FreeBSD build 421 4222005-06-26 - v0.4.3 423 * fixed PMKSA caching to copy User-Name and Class attributes so that 424 RADIUS accounting gets correct information 425 * start RADIUS accounting only after successful completion of WPA 426 4-Way Handshake if WPA-PSK is used 427 * fixed PMKSA caching for the case where STA (re)associates without 428 first disassociating 429 4302005-06-12 - v0.4.2 431 * EAP-PAX is now registered as EAP type 46 432 * fixed EAP-PAX MAC calculation 433 * fixed EAP-PAX CK and ICK key derivation 434 * renamed eap_authenticator configuration variable to eap_server to 435 better match with RFC 3748 (EAP) terminology 436 * driver_test: added support for testing hostapd with wpa_supplicant 437 by using test driver interface without any kernel drivers or network 438 cards 439 4402005-05-22 - v0.4.1 441 * fixed RADIUS server initialization when only auth or acct server 442 is configured and the other one is left empty 443 * driver_madwifi: added support for RADIUS accounting 444 * driver_madwifi: added preliminary support for compiling against 'BSD' 445 branch of madwifi CVS tree 446 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 447 without disassociation 448 * added support for reading additional certificates from PKCS#12 files 449 and adding them to the certificate chain 450 * fixed RADIUS Class attribute processing to only use Access-Accept 451 packets to update Class; previously, other RADIUS authentication 452 packets could have cleared Class attribute 453 * added support for more than one Class attribute in RADIUS packets 454 * added support for verifying certificate revocation list (CRL) when 455 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 456 options 'check_crl'; CRL must be included in the ca_cert file for now 457 4582005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 459 * added support for including network information into 460 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 461 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 462 * fixed a bug which caused some RSN pre-authentication cases to use 463 freed memory and potentially crash hostapd 464 * fixed private key loading for cases where passphrase is not set 465 * added support for sending TLS alerts and aborting authentication 466 when receiving a TLS alert 467 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 468 authenticator 469 * fixed PMKSA caching (EAP authentication was not skipped correctly 470 with the new state machine changes from IEEE 802.1X draft) 471 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 472 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 473 to be added to .config to include IPv6 support); for RADIUS server, 474 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 475 in RADIUS clients file can then use IPv6 format 476 * added experimental support for EAP-PAX 477 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 478 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 479 4802005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 481 4822005-01-23 - v0.3.5 483 * added support for configuring a forced PEAP version based on the 484 Phase 1 identity 485 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 486 to terminate authentication 487 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 488 draft 489 * clear accounting data in the driver when starting a new accounting 490 session 491 * driver_madwifi: filter wireless events based on ifindex to allow more 492 than one network interface to be used 493 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 494 setting if the packet does not pass MIC verification (e.g., due to 495 incorrect PSK); previously, message 1/4 was not tried again if an 496 invalid message 2/4 was received 497 * fixed reconfiguration of RADIUS client retransmission timer when 498 adding a new message to the pending list; previously, timer was not 499 updated at this point and if there was a pending message with long 500 time for the next retry, the new message needed to wait that long for 501 its first retry, too 502 5032005-01-09 - v0.3.4 504 * added support for configuring multiple allowed EAP types for Phase 2 505 authentication (EAP-PEAP, EAP-TTLS) 506 * fixed EAPOL-Start processing to trigger WPA reauthentication 507 (previously, only EAPOL authentication was done) 508 5092005-01-02 - v0.3.3 510 * added support for EAP-PEAP in the integrated EAP authenticator 511 * added support for EAP-GTC in the integrated EAP authenticator 512 * added support for configuring list of EAP methods for Phase 1 so that 513 the integrated EAP authenticator can, e.g., use the wildcard entry 514 for EAP-TLS and EAP-PEAP 515 * added support for EAP-TTLS in the integrated EAP authenticator 516 * added support for EAP-SIM in the integrated EAP authenticator 517 * added support for using hostapd as a RADIUS authentication server 518 with the integrated EAP authenticator taking care of EAP 519 authentication (new hostapd.conf options: radius_server_clients and 520 radius_server_auth_port); this is not included in default build; use 521 CONFIG_RADIUS_SERVER=y in .config to include 522 5232004-12-19 - v0.3.2 524 * removed 'daemonize' configuration file option since it has not really 525 been used at all for more than year 526 * driver_madwifi: fixed group key setup and added get_ssid method 527 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 528 5292004-12-12 - v0.3.1 530 * added support for integrated EAP-TLS authentication (new hostapd.conf 531 variables: ca_cert, server_cert, private_key, private_key_passwd); 532 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 533 external RADIUS server 534 * added support for reading PKCS#12 (PFX) files (as a replacement for 535 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 536 5372004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 538 * added support for Acct-{Input,Output}-Gigawords 539 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 540 * added support for RADIUS Authentication Client MIB (RFC2618) 541 * added support for RADIUS Accounting Client MIB (RFC2620) 542 * made EAP re-authentication period configurable (eap_reauth_period) 543 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 544 * fixed EAPOL state machine to stop if STA is removed during 545 eapol_sm_step(); this fixes at least one segfault triggering bug with 546 IEEE 802.11i pre-authentication 547 * added support for multiple WPA pre-shared keys (e.g., one for each 548 client MAC address or keys shared by a group of clients); 549 new hostapd.conf field wpa_psk_file for setting path to a text file 550 containing PSKs, see hostapd.wpa_psk for an example 551 * added support for multiple driver interfaces to allow hostapd to be 552 used with other drivers 553 * added wired authenticator driver interface (driver=wired in 554 hostapd.conf, see wired.conf for example configuration) 555 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 556 madwifi.conf for example configuration; Note: include files from 557 madwifi project is needed for building and a configuration file, 558 .config, needs to be created in hostapd directory with 559 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 560 build) 561 * fixed an alignment issue that could cause SHA-1 to fail on some 562 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 563 align variables) 564 * fixed RADIUS reconnection after an error in sending interim 565 accounting packets 566 * added hostapd control interface for external programs and an example 567 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 568 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 569 'hostapd_cli sta <addr>') 570 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 571 * added support for strict GTK rekeying (wpa_strict_rekey in 572 hostapd.conf) 573 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 574 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 575 IEEE 802.11F-2003) 576 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 577 note: .config needs to be created in hostapd directory with 578 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 579 build) 580 * dual-licensed hostapd (GPLv2 and BSD licenses) 581 * fixed RADIUS accounting to generate a new session id for cases where 582 a station reassociates without first being complete deauthenticated 583 * fixed STA disassociation handler to mark next timeout state to 584 deauthenticate the station, i.e., skip long wait for inactivity poll 585 and extra disassociation, if the STA disassociates without 586 deauthenticating 587 * added integrated EAP authenticator that can be used instead of 588 external RADIUS authentication server; currently, only EAP-MD5 is 589 supported, so this cannot yet be used for key distribution; the EAP 590 method interface is generic, though, so adding new EAP methods should 591 be straightforward; new hostapd.conf variables: 'eap_authenticator' 592 and 'eap_user_file'; this obsoletes "minimal authentication server" 593 ('minimal_eap' in hostapd.conf) which is now removed 594 * added support for FreeBSD and driver interface for the BSD net80211 595 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 596 .config); please note that some of the required kernel mods have not 597 yet been committed 598 5992004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 600 * fixed some accounting cases where Accounting-Start was sent when 601 IEEE 802.1X port was being deauthorized 602 6032004-06-20 - v0.2.3 604 * modified RADIUS client to re-connect the socket in case of certain 605 error codes that are generated when a network interface state is 606 changes (e.g., when IP address changes or the interface is set UP) 607 * fixed couple of cases where EAPOL state for a station was freed 608 twice causing a segfault for hostapd 609 * fixed couple of bugs in processing WPA deauthentication (freed data 610 was used) 611 6122004-05-31 - v0.2.2 613 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 614 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 615 cases where STAs dropped multicast frames as replay attacks 616 * added support for copying RADIUS Attribute 'Class' from 617 authentication messages into accounting messages 618 * send canned EAP failure if RADIUS server sends Access-Reject without 619 EAP message (previously, Supplicant was not notified in this case) 620 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 621 not start EAPOL state machines if the STA selected to use WPA-PSK) 622 6232004-05-06 - v0.2.1 624 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 625 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 626 (i.e., IEEE 802.11i/D3.0) 627 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 628 - both WPA-PSK and WPA-RADIUS/EAP are supported 629 - PMKSA caching and pre-authentication 630 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 631 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 632 rsn_preauth, rsn_preauth_interfaces 633 * fixed interim accounting to remove any pending accounting messages 634 to the STA before sending a new one 635 6362004-02-15 - v0.2.0 637 * added support for Acct-Interim-Interval: 638 - draft-ietf-radius-acct-interim-01.txt 639 - use Acct-Interim-Interval attribute from Access-Accept if local 640 'radius_acct_interim_interval' is not set 641 - allow different update intervals for each STA 642 * fixed event loop to call signal handlers only after returning from 643 the real signal handler 644 * reset sta->timeout_next after successful association to make sure 645 that the previously registered inactivity timer will not remove the 646 STA immediately (e.g., if STA deauthenticates and re-associates 647 before the timer is triggered). 648 * added new hostapd.conf variable, nas_identifier, that can be used to 649 add an optional RADIUS Attribute, NAS-Identifier, into authentication 650 and accounting messages 651 * added support for Accounting-On and Accounting-Off messages 652 * fixed accounting session handling to send Accounting-Start only once 653 per session and not to send Accounting-Stop if the session was not 654 initialized properly 655 * fixed Accounting-Stop statistics in cases where the message was 656 previously sent after the kernel entry for the STA (and/or IEEE 657 802.1X data) was removed 658 659 660Note: 661 662Older changes up to and including v0.1.0 are included in the ChangeLog 663of the Host AP driver. 664
