1 ChangeLog for hostapd 2 3 2012-05-10 - v1.0 4 * Add channel selection support in hostapd. See hostapd.conf. 5 * Add support for IEEE 802.11v Time Advertisement mechanism with UTC 6 TSF offset. See hostapd.conf for config info. 7 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 8 This allows the driver to use PS buffering of Deauthentication and 9 Disassociation frames when the STA is in power save sleep. Only 10 available with drivers that provide TX status events for Deauth/ 11 Disassoc frames (nl80211). 12 * Allow PMKSA caching to be disabled on the Authenticator. See 13 hostap.conf config parameter disable_pmksa_caching. 14 * atheros: Add support for IEEE 802.11w configuration. 15 * bsd: Add support for setting HT values in IFM_MMASK. 16 * Allow client isolation to be configured with ap_isolate. Client 17 isolation can be used to prevent low-level bridging of frames 18 between associated stations in the BSS. By default, this bridging 19 is allowed. 20 * Allow coexistance of HT BSSes with WEP/TKIP BSSes. 21 * Add require_ht config parameter, which can be used to configure 22 hostapd to reject association with any station that does not support 23 HT PHY. 24 * Add support for writing debug log to a file using "-f" option. Also 25 add relog CLI command to re-open the log file. 26 * Add bridge handling for WDS STA interfaces. By default they are 27 added to the configured bridge of the AP interface (if present), 28 but the user can also specify a separate bridge using cli command 29 wds_bridge. 30 * hostapd_cli: 31 - Add wds_bridge command for specifying bridge for WDS STA 32 interfaces. 33 - Add relog command for reopening log file. 34 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 35 due to inactivity. 36 - Add wps_config ctrl_interface command for configuring AP. This 37 command can be used to configure the AP using the internal WPS 38 registrar. It works in the same way as new AP settings received 39 from an ER. 40 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 41 - Add command get version, that returns hostapd version string. 42 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 43 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 44 notification to the STA. 45 * Allow AP mode to disconnect STAs based on low ACK condition (when 46 the data connection is not working properly, e.g., due to the STA 47 going outside the range of the AP). Disabled by default, enable by 48 config option disassoc_low_ack. 49 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 50 config file. 51 * WPS: 52 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 53 in WPS-NEW-AP-SETTINGS. 54 - Dispatch more WPS events through hostapd ctrl_iface. 55 - Add mechanism for indicating non-standard WPS errors. 56 - Change concurrent radio AP to use only one WPS UPnP instance. 57 - Add wps_check_pin command for processing PIN from user input. 58 UIs can use this command to process a PIN entered by a user and to 59 validate the checksum digit (if present). 60 - Add hostap_cli get_config command to display current AP config. 61 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 62 runtime and support dynamic AP PIN management. 63 - Disable AP PIN after 10 consecutive failures. Slow down attacks 64 on failures up to 10. 65 - Allow AP to start in Enrollee mode without AP PIN for probing, 66 to be compatible with Windows 7. 67 - Add Config Error into WPS-FAIL events to provide more info 68 to the user on how to resolve the issue. 69 - When controlling multiple interfaces: 70 - apply WPS commands to all interfaces configured to use WPS 71 - apply WPS config changes to all interfaces that use WPS 72 - when an attack is detected on any interface, disable AP PIN on 73 all interfaces 74 * WPS ER: 75 - Show SetSelectedRegistrar events as ctrl_iface events. 76 - Add special AP Setup Locked mode to allow read only ER. 77 ap_setup_locked=2 can now be used to enable a special mode where 78 WPS ER can learn the current AP settings, but cannot change them. 79 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 80 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 81 for testing protocol extensibility. 82 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 83 workarounds. 84 - Add support for AuthorizedMACs attribute. 85 * TDLS: 86 - Allow TDLS use or TDLS channel switching in the BSS to be 87 prohibited in the BSS, using config params tdls_prohibit and 88 tdls_prohibit_chan_switch. 89 * EAP server: Add support for configuring fragment size (see 90 fragment_size in hostapd.conf). 91 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 92 wlantest can be used to capture frames from a monitor interface 93 for realtime capturing or from pcap files for offline analysis. 94 * Interworking: Support added for 802.11u. Enable in .config with 95 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 96 interworking. 97 * Android: Add build and runtime support for Android hostapd. 98 * Add a new debug message level for excessive information. Use 99 -ddd to enable. 100 * TLS: Add support for tls_disable_time_checks=1 in client mode. 101 * Internal TLS: 102 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 103 CONFIG_TLSV11. 104 - Add domainComponent parser for X.509 names 105 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 106 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 107 Move HT IEs to be later in (Re)Assoc Resp. 108 * Many bugfixes. 109 110 2010-04-18 - v0.7.2 111 * fix WPS internal Registrar use when an external Registrar is also 112 active 113 * bsd: Cleaned up driver wrapper and added various low-level 114 configuration options 115 * TNC: fixed issues with fragmentation 116 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 117 interoperate with other implementations; may potentially breaks 118 compatibility with older wpa_supplicant/hostapd versions) 119 * cleaned up driver wrapper API for multi-BSS operations 120 * nl80211: fix multi-BSS and VLAN operations 121 * fix number of issues with IEEE 802.11r/FT; this version is not 122 backwards compatible with old versions 123 * add SA Query Request processing in AP mode (IEEE 802.11w) 124 * fix IGTK PN in group rekeying (IEEE 802.11w) 125 * fix WPS PBC session overlap detection to use correct attribute 126 * hostapd_notif_Assoc() can now be called with all IEs to simplify 127 driver wrappers 128 * work around interoperability issue with some WPS External Registrar 129 implementations 130 * nl80211: fix WPS IE update 131 * hostapd_cli: add support for action script operations (run a script 132 on hostapd events) 133 * fix DH padding with internal crypto code (mainly, for WPS) 134 * fix WPS association with both WPS IE and WPA/RSN IE present with 135 driver wrappers that use hostapd MLME (e.g., nl80211) 136 137 2010-01-16 - v0.7.1 138 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 139 is not fully backwards compatible, so out-of-tree driver wrappers 140 will need modifications 141 * cleaned up various module interfaces 142 * merge hostapd and wpa_supplicant developers' documentation into a 143 single document 144 * fixed HT Capabilities IE with nl80211 drivers 145 * moved generic AP functionality code into src/ap 146 * WPS: handle Selected Registrar as union of info from all Registrars 147 * remove obsolte Prism54.org driver wrapper 148 * added internal debugging mechanism with backtrace support and memory 149 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 150 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 151 * WPS: add support for dynamically selecting whether to provision the 152 PSK as an ASCII passphrase or PSK 153 * added support for WDS (4-address frame) mode with per-station virtual 154 interfaces (wds_sta=1 in config file; only supported with 155 driver=nl80211 for now) 156 * fixed WPS Probe Request processing to handle missing required 157 attribute 158 * fixed PKCS#12 use with OpenSSL 1.0.0 159 * detect bridge interface automatically so that bridge parameter in 160 hostapd.conf becomes optional (though, it may now be used to 161 automatically add then WLAN interface into a bridge with 162 driver=nl80211) 163 164 2009-11-21 - v0.7.0 165 * increased hostapd_cli ping interval to 5 seconds and made this 166 configurable with a new command line options (-G<seconds>) 167 * driver_nl80211: use Linux socket filter to improve performance 168 * added support for external Registrars with WPS (UPnP transport) 169 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 170 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 171 reported correctly; TX/RX packets not yet available from kernel) 172 * added support for WPS USBA out-of-band mechanism with USB Flash 173 Drives (UFD) (CONFIG_WPS_UFD=y) 174 * fixed EAPOL/EAP reauthentication when using an external RADIUS 175 authentication server 176 * fixed TNC with EAP-TTLS 177 * fixed IEEE 802.11r key derivation function to match with the standard 178 (note: this breaks interoperability with previous version) [Bug 303] 179 * fixed SHA-256 based key derivation function to match with the 180 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 181 (note: this breaks interoperability with previous version) [Bug 307] 182 * added number of code size optimizations to remove unnecessary 183 functionality from the program binary based on build configuration 184 (part of this automatic; part configurable with CONFIG_NO_* build 185 options) 186 * use shared driver wrapper files with wpa_supplicant 187 * driver_nl80211: multiple updates to provide support for new Linux 188 nl80211/mac80211 functionality 189 * updated management frame protection to use IEEE Std 802.11w-2009 190 * fixed number of small WPS issues and added workarounds to 191 interoperate with common deployed broken implementations 192 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 193 or modify primary/secondary channels if needed based on neighboring 194 networks 195 * added support for NFC out-of-band mechanism with WPS 196 * added preliminary support for IEEE 802.11r RIC processing 197 198 2009-01-06 - v0.6.7 199 * added support for Wi-Fi Protected Setup (WPS) 200 (hostapd can now be configured to act as an integrated WPS Registrar 201 and provision credentials for WPS Enrollees using PIN and PBC 202 methods; external wireless Registrar can configure the AP, but 203 external WLAN Manager Registrars are not supported); WPS support can 204 be enabled by adding CONFIG_WPS=y into .config and setting the 205 runtime configuration variables in hostapd.conf (see WPS section in 206 the example configuration file); new hostapd_cli commands wps_pin and 207 wps_pbc are used to configure WPS negotiation; see README-WPS for 208 more details 209 * added IEEE 802.11n HT capability configuration (ht_capab) 210 * added support for generating Country IE based on nl80211 regulatory 211 information (added if ieee80211d=1 in configuration) 212 * fixed WEP authentication (both Open System and Shared Key) with 213 mac80211 214 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 215 * added support for using driver_test over UDP socket 216 * changed EAP-GPSK to use the IANA assigned EAP method type 51 217 * updated management frame protection to use IEEE 802.11w/D7.0 218 * fixed retransmission of EAP requests if no response is received 219 220 2008-11-23 - v0.6.6 221 * added a new configuration option, wpa_ptk_rekey, that can be used to 222 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 223 TKIP deficiencies 224 * updated OpenSSL code for EAP-FAST to use an updated version of the 225 session ticket overriding API that was included into the upstream 226 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 227 needed with that version anymore) 228 * changed channel flags configuration to read the information from 229 the driver (e.g., via driver_nl80211 when using mac80211) instead of 230 using hostapd as the source of the regulatory information (i.e., 231 information from CRDA is now used with mac80211); this allows 5 GHz 232 channels to be used with hostapd (if allowed in the current 233 regulatory domain) 234 * fixed EAP-TLS message processing for the last TLS message if it is 235 large enough to require fragmentation (e.g., if a large Session 236 Ticket data is included) 237 * fixed listen interval configuration for nl80211 drivers 238 239 2008-11-01 - v0.6.5 240 * added support for SHA-256 as X.509 certificate digest when using the 241 internal X.509/TLSv1 implementation 242 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 243 identity lengths) 244 * fixed internal TLSv1 implementation for abbreviated handshake (used 245 by EAP-FAST server) 246 * added support for setting VLAN ID for STAs based on local MAC ACL 247 (accept_mac_file) as an alternative for RADIUS server-based 248 configuration 249 * updated management frame protection to use IEEE 802.11w/D6.0 250 (adds a new association ping to protect against unauthenticated 251 authenticate or (re)associate request frames dropping association) 252 * added support for using SHA256-based stronger key derivation for WPA2 253 (IEEE 802.11w) 254 * added new "driver wrapper" for RADIUS-only configuration 255 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 256 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 257 is enabled in configuration 258 * changed EAP-FAST configuration to use separate fields for A-ID and 259 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 260 16-octet len binary value for better interoperability with some peer 261 implementations; eap_fast_a_id is now configured as a hex string 262 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 263 configuration (wireless-testing.git and Linux kernel releases 264 starting from 2.6.29) 265 266 2008-08-10 - v0.6.4 267 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 268 Identity Request if identity is already known 269 * added support for EAP Sequences in EAP-FAST Phase 2 270 * added support for EAP-TNC (Trusted Network Connect) 271 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 272 changes needed to run two methods in sequence (IF-T) and the IF-IMV 273 and IF-TNCCS interfaces from TNCS) 274 * added support for optional cryptobinding with PEAPv0 275 * added fragmentation support for EAP-TNC 276 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 277 data 278 * added support for opportunistic key caching (OKC) 279 280 2008-02-22 - v0.6.3 281 * fixed Reassociation Response callback processing when using internal 282 MLME (driver_{hostap,nl80211,test}.c) 283 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 284 * copy optional Proxy-State attributes into RADIUS response when acting 285 as a RADIUS authentication server 286 * fixed EAPOL state machine to handle a case in which no response is 287 received from the RADIUS authentication server; previous version 288 could have triggered a crash in some cases after a timeout 289 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 290 be used 291 * added a workaround for EAP-SIM/AKA peers that include incorrect null 292 termination in the username 293 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 294 attribute in notification messages only when using fast 295 reauthentication 296 * fixed EAP-SIM Start response processing for fast reauthentication 297 case 298 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 299 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 300 301 2008-01-01 - v0.6.2 302 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 303 lengths properly to avoid potential crash caused by invalid messages 304 * added data structure for storing allocated buffers (struct wpabuf); 305 this does not affect hostapd usage, but many of the APIs changed 306 and various interfaces (e.g., EAP) is not compatible with old 307 versions 308 * added support for protecting EAP-AKA/Identity messages with 309 AT_CHECKCODE (optional feature in RFC 4187) 310 * added support for protected result indication with AT_RESULT_IND for 311 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 312 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 313 EAP server configuration; previously all four were enabled for every 314 phase 2 user, now all four are disabled by default and need to be 315 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 316 TTLS-MSCHAPV2 317 * removed old debug printing mechanism and the related 'debug' 318 parameter in the configuration file; debug verbosity is now set with 319 -d (or -dd) command line arguments 320 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 321 only shared key/password authentication is supported in this version 322 323 2007-11-24 - v0.6.1 324 * added experimental, integrated TLSv1 server implementation with the 325 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 326 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 327 .config); this can be useful, e.g., if the target system does not 328 have a suitable TLS library and a minimal code size is required 329 * added support for EAP-FAST server method to the integrated EAP 330 server 331 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 332 draft (draft-ietf-emu-eap-gpsk-07.txt) 333 * added a new configuration parameter, rsn_pairwise, to allow different 334 pairwise cipher suites to be enabled for WPA and RSN/WPA2 335 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 336 either need to support this or will have to use the WPA/RSN IEs from 337 hostapd; currently, the included madwifi and bsd driver interfaces do 338 not have support for this) 339 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 340 341 2007-05-28 - v0.6.0 342 * added experimental IEEE 802.11r/D6.0 support 343 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 344 * updated EAP-PSK to use the IANA-allocated EAP type 47 345 * fixed EAP-PSK bit ordering of the Flags field 346 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 347 by reading wpa_psk_file [Bug 181] 348 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 349 * fixed IPv6 connection to RADIUS accounting server 350 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 351 draft (draft-ietf-emu-eap-gpsk-04.txt) 352 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 353 entries instead of only using the same three triplets every time 354 (this does not work properly with tests using multiple clients, but 355 provides bit better triplet data for testing a single client; anyway, 356 if a better quality triplets are needed, GSM-Milenage should be used 357 instead of hardcoded triplet file) 358 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 359 in Success Request [Bug 203] 360 * added support for sending EAP-AKA Notifications in error cases 361 * updated to use IEEE 802.11w/D2.0 for management frame protection 362 (still experimental) 363 * RADIUS server: added support for processing duplicate messages 364 (retransmissions from RADIUS client) by replying with the previous 365 reply 366 367 2006-11-24 - v0.5.6 368 * added support for configuring and controlling multiple BSSes per 369 radio interface (bss=<ifname> in hostapd.conf); this is only 370 available with Devicescape and test driver interfaces 371 * fixed PMKSA cache update in the end of successful RSN 372 pre-authentication 373 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 374 for each STA based on RADIUS Access-Accept attributes); this requires 375 VLAN support from the kernel driver/802.11 stack and this is 376 currently only available with Devicescape and test driver interfaces 377 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 378 and IEEE 802.1X without WEP) 379 * removed STAKey handshake since PeerKey handshake has replaced it in 380 IEEE 802.11ma and there are no known deployments of STAKey 381 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 382 draft (draft-ietf-emu-eap-gpsk-01.txt) 383 * added preliminary implementation of IEEE 802.11w/D1.0 (management 384 frame protection) 385 (Note: this requires driver support to work properly.) 386 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 387 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 388 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 389 parameters from a text file to make it possible to implement proper 390 GSM/UMTS authentication server for multiple SIM/USIM cards using 391 EAP-SIM/EAP-AKA 392 * fixed session timeout processing with drivers that do not use 393 ieee802_11.c (e.g., madwifi) 394 395 2006-08-27 - v0.5.5 396 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 397 hostapd (e.g., to initialize wired network authentication based on an 398 external signal) 399 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 400 using WPA2 even if PMKSA caching is not used 401 * added -P<pid file> argument for hostapd to write the current process 402 id into a file 403 * added support for RADIUS Authentication Server MIB (RFC 2619) 404 405 2006-06-20 - v0.5.4 406 * fixed nt_password_hash build [Bug 144] 407 * added PeerKey handshake implementation for IEEE 802.11e 408 direct link setup (DLS) to replace STAKey handshake 409 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 410 draft-clancy-emu-eap-shared-secret-00.txt) 411 * fixed a segmentation fault when RSN pre-authentication was completed 412 successfully [Bug 152] 413 414 2006-04-27 - v0.5.3 415 * do not build nt_password_hash and hlr_auc_gw by default to avoid 416 requiring a TLS library for a successful build; these programs can be 417 build with 'make nt_password_hash' and 'make hlr_auc_gw' 418 * added a new configuration option, eapol_version, that can be used to 419 set EAPOL version to 1 (default is 2) to work around broken client 420 implementations that drop EAPOL frames which use version number 2 421 [Bug 89] 422 * added support for EAP-SAKE (no EAP method number allocated yet, so 423 this is using the same experimental type 255 as EAP-PSK) 424 * fixed EAP-MSCHAPv2 message length validation 425 426 2006-03-19 - v0.5.2 427 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 428 logging was enabled, hostapd could trigger a segmentation fault in 429 vsyslog on some CPU -- C library combinations 430 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 431 program to make it easier to use for implementing real SS7 gateway; 432 eap_sim_db is not anymore used as a file name for GSM authentication 433 triplets; instead, it is path to UNIX domain socket that will be used 434 to communicate with the external gateway program (e.g., hlr_auc_gw) 435 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 436 local information (GSM authentication triplets from a text file and 437 hardcoded AKA authentication data); this can be used to test EAP-SIM 438 and EAP-AKA 439 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 440 to make it possible to test EAP-AKA with real USIM cards (this is 441 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 442 to enable this) 443 * driver_madwifi: added support for getting station RSN IE from 444 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 445 broken with earlier change (r1357) in the driver 446 * changed EAP method registration to use a dynamic list of methods 447 instead of a static list generated at build time 448 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 449 [Bug 125] 450 * added ap_max_inactivity configuration parameter 451 452 2006-01-29 - v0.5.1 453 * driver_test: added better support for multiple APs and STAs by using 454 a directory with sockets that include MAC address for each device in 455 the name (test_socket=DIR:/tmp/test) 456 * added support for EAP expanded type (vendor specific EAP methods) 457 458 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 459 * added experimental STAKey handshake implementation for IEEE 802.11e 460 direct link setup (DLS); note: this is disabled by default in both 461 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 462 and stakey=1) 463 * added support for EAP methods to use callbacks to external programs 464 by buffering a pending request and processing it after the EAP method 465 is ready to continue 466 * improved EAP-SIM database interface to allow external request to GSM 467 HLR/AuC without blocking hostapd process 468 * added support for using EAP-SIM pseudonyms and fast re-authentication 469 * added support for EAP-AKA in the integrated EAP authenticator 470 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 471 user database to allow EAP-SIM/AKA selection without extra roundtrip 472 for EAP-Nak negotiation 473 * added support for storing EAP user password as NtPasswordHash instead 474 of plaintext password when using MSCHAP or MSCHAPv2 for 475 authentication (hash:<16-octet hex value>); added nt_password_hash 476 tool for hashing password to generate NtPasswordHash 477 478 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 479 * driver_wired: fixed EAPOL sending to optionally use PAE group address 480 as the destination instead of supplicant MAC address; this is 481 disabled by default, but should be enabled with use_pae_group_addr=1 482 in configuration file if the wired interface is used by only one 483 device at the time (common switch configuration) 484 * driver_madwifi: configure driver to use TKIP countermeasures in order 485 to get correct behavior (IEEE 802.11 association failing; previously, 486 association succeeded, but hostpad forced disassociation immediately) 487 * driver_madwifi: added support for madwifi-ng 488 489 2005-10-27 - v0.4.6 490 * added support for replacing user identity from EAP with RADIUS 491 User-Name attribute from Access-Accept message, if that is included, 492 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 493 tunneled identity into accounting messages when the RADIUS server 494 does not support better way of doing this with Class attribute) 495 * driver_madwifi: fixed EAPOL packet receive for configuration where 496 ath# is part of a bridge interface 497 * added a configuration file and log analyzer script for logwatch 498 * fixed EAPOL state machine step function to process all state 499 transitions before processing new events; this resolves a race 500 condition in which EAPOL-Start message could trigger hostapd to send 501 two EAP-Response/Identity frames to the authentication server 502 503 2005-09-25 - v0.4.5 504 * added client CA list to the TLS certificate request in order to make 505 it easier for the client to select which certificate to use 506 * added experimental support for EAP-PSK 507 * added support for WE-19 (hostap, madwifi) 508 509 2005-08-21 - v0.4.4 510 * fixed build without CONFIG_RSN_PREAUTH 511 * fixed FreeBSD build 512 513 2005-06-26 - v0.4.3 514 * fixed PMKSA caching to copy User-Name and Class attributes so that 515 RADIUS accounting gets correct information 516 * start RADIUS accounting only after successful completion of WPA 517 4-Way Handshake if WPA-PSK is used 518 * fixed PMKSA caching for the case where STA (re)associates without 519 first disassociating 520 521 2005-06-12 - v0.4.2 522 * EAP-PAX is now registered as EAP type 46 523 * fixed EAP-PAX MAC calculation 524 * fixed EAP-PAX CK and ICK key derivation 525 * renamed eap_authenticator configuration variable to eap_server to 526 better match with RFC 3748 (EAP) terminology 527 * driver_test: added support for testing hostapd with wpa_supplicant 528 by using test driver interface without any kernel drivers or network 529 cards 530 531 2005-05-22 - v0.4.1 532 * fixed RADIUS server initialization when only auth or acct server 533 is configured and the other one is left empty 534 * driver_madwifi: added support for RADIUS accounting 535 * driver_madwifi: added preliminary support for compiling against 'BSD' 536 branch of madwifi CVS tree 537 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 538 without disassociation 539 * added support for reading additional certificates from PKCS#12 files 540 and adding them to the certificate chain 541 * fixed RADIUS Class attribute processing to only use Access-Accept 542 packets to update Class; previously, other RADIUS authentication 543 packets could have cleared Class attribute 544 * added support for more than one Class attribute in RADIUS packets 545 * added support for verifying certificate revocation list (CRL) when 546 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 547 options 'check_crl'; CRL must be included in the ca_cert file for now 548 549 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 550 * added support for including network information into 551 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 552 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 553 * fixed a bug which caused some RSN pre-authentication cases to use 554 freed memory and potentially crash hostapd 555 * fixed private key loading for cases where passphrase is not set 556 * added support for sending TLS alerts and aborting authentication 557 when receiving a TLS alert 558 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 559 authenticator 560 * fixed PMKSA caching (EAP authentication was not skipped correctly 561 with the new state machine changes from IEEE 802.1X draft) 562 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 563 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 564 to be added to .config to include IPv6 support); for RADIUS server, 565 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 566 in RADIUS clients file can then use IPv6 format 567 * added experimental support for EAP-PAX 568 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 569 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 570 571 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 572 573 2005-01-23 - v0.3.5 574 * added support for configuring a forced PEAP version based on the 575 Phase 1 identity 576 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 577 to terminate authentication 578 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 579 draft 580 * clear accounting data in the driver when starting a new accounting 581 session 582 * driver_madwifi: filter wireless events based on ifindex to allow more 583 than one network interface to be used 584 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 585 setting if the packet does not pass MIC verification (e.g., due to 586 incorrect PSK); previously, message 1/4 was not tried again if an 587 invalid message 2/4 was received 588 * fixed reconfiguration of RADIUS client retransmission timer when 589 adding a new message to the pending list; previously, timer was not 590 updated at this point and if there was a pending message with long 591 time for the next retry, the new message needed to wait that long for 592 its first retry, too 593 594 2005-01-09 - v0.3.4 595 * added support for configuring multiple allowed EAP types for Phase 2 596 authentication (EAP-PEAP, EAP-TTLS) 597 * fixed EAPOL-Start processing to trigger WPA reauthentication 598 (previously, only EAPOL authentication was done) 599 600 2005-01-02 - v0.3.3 601 * added support for EAP-PEAP in the integrated EAP authenticator 602 * added support for EAP-GTC in the integrated EAP authenticator 603 * added support for configuring list of EAP methods for Phase 1 so that 604 the integrated EAP authenticator can, e.g., use the wildcard entry 605 for EAP-TLS and EAP-PEAP 606 * added support for EAP-TTLS in the integrated EAP authenticator 607 * added support for EAP-SIM in the integrated EAP authenticator 608 * added support for using hostapd as a RADIUS authentication server 609 with the integrated EAP authenticator taking care of EAP 610 authentication (new hostapd.conf options: radius_server_clients and 611 radius_server_auth_port); this is not included in default build; use 612 CONFIG_RADIUS_SERVER=y in .config to include 613 614 2004-12-19 - v0.3.2 615 * removed 'daemonize' configuration file option since it has not really 616 been used at all for more than year 617 * driver_madwifi: fixed group key setup and added get_ssid method 618 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 619 620 2004-12-12 - v0.3.1 621 * added support for integrated EAP-TLS authentication (new hostapd.conf 622 variables: ca_cert, server_cert, private_key, private_key_passwd); 623 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 624 external RADIUS server 625 * added support for reading PKCS#12 (PFX) files (as a replacement for 626 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 627 628 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 629 * added support for Acct-{Input,Output}-Gigawords 630 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 631 * added support for RADIUS Authentication Client MIB (RFC2618) 632 * added support for RADIUS Accounting Client MIB (RFC2620) 633 * made EAP re-authentication period configurable (eap_reauth_period) 634 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 635 * fixed EAPOL state machine to stop if STA is removed during 636 eapol_sm_step(); this fixes at least one segfault triggering bug with 637 IEEE 802.11i pre-authentication 638 * added support for multiple WPA pre-shared keys (e.g., one for each 639 client MAC address or keys shared by a group of clients); 640 new hostapd.conf field wpa_psk_file for setting path to a text file 641 containing PSKs, see hostapd.wpa_psk for an example 642 * added support for multiple driver interfaces to allow hostapd to be 643 used with other drivers 644 * added wired authenticator driver interface (driver=wired in 645 hostapd.conf, see wired.conf for example configuration) 646 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 647 madwifi.conf for example configuration; Note: include files from 648 madwifi project is needed for building and a configuration file, 649 .config, needs to be created in hostapd directory with 650 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 651 build) 652 * fixed an alignment issue that could cause SHA-1 to fail on some 653 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 654 align variables) 655 * fixed RADIUS reconnection after an error in sending interim 656 accounting packets 657 * added hostapd control interface for external programs and an example 658 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 659 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 660 'hostapd_cli sta <addr>') 661 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 662 * added support for strict GTK rekeying (wpa_strict_rekey in 663 hostapd.conf) 664 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 665 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 666 IEEE 802.11F-2003) 667 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 668 note: .config needs to be created in hostapd directory with 669 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 670 build) 671 * dual-licensed hostapd (GPLv2 and BSD licenses) 672 * fixed RADIUS accounting to generate a new session id for cases where 673 a station reassociates without first being complete deauthenticated 674 * fixed STA disassociation handler to mark next timeout state to 675 deauthenticate the station, i.e., skip long wait for inactivity poll 676 and extra disassociation, if the STA disassociates without 677 deauthenticating 678 * added integrated EAP authenticator that can be used instead of 679 external RADIUS authentication server; currently, only EAP-MD5 is 680 supported, so this cannot yet be used for key distribution; the EAP 681 method interface is generic, though, so adding new EAP methods should 682 be straightforward; new hostapd.conf variables: 'eap_authenticator' 683 and 'eap_user_file'; this obsoletes "minimal authentication server" 684 ('minimal_eap' in hostapd.conf) which is now removed 685 * added support for FreeBSD and driver interface for the BSD net80211 686 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 687 .config); please note that some of the required kernel mods have not 688 yet been committed 689 690 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 691 * fixed some accounting cases where Accounting-Start was sent when 692 IEEE 802.1X port was being deauthorized 693 694 2004-06-20 - v0.2.3 695 * modified RADIUS client to re-connect the socket in case of certain 696 error codes that are generated when a network interface state is 697 changes (e.g., when IP address changes or the interface is set UP) 698 * fixed couple of cases where EAPOL state for a station was freed 699 twice causing a segfault for hostapd 700 * fixed couple of bugs in processing WPA deauthentication (freed data 701 was used) 702 703 2004-05-31 - v0.2.2 704 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 705 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 706 cases where STAs dropped multicast frames as replay attacks 707 * added support for copying RADIUS Attribute 'Class' from 708 authentication messages into accounting messages 709 * send canned EAP failure if RADIUS server sends Access-Reject without 710 EAP message (previously, Supplicant was not notified in this case) 711 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 712 not start EAPOL state machines if the STA selected to use WPA-PSK) 713 714 2004-05-06 - v0.2.1 715 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 716 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 717 (i.e., IEEE 802.11i/D3.0) 718 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 719 - both WPA-PSK and WPA-RADIUS/EAP are supported 720 - PMKSA caching and pre-authentication 721 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 722 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 723 rsn_preauth, rsn_preauth_interfaces 724 * fixed interim accounting to remove any pending accounting messages 725 to the STA before sending a new one 726 727 2004-02-15 - v0.2.0 728 * added support for Acct-Interim-Interval: 729 - draft-ietf-radius-acct-interim-01.txt 730 - use Acct-Interim-Interval attribute from Access-Accept if local 731 'radius_acct_interim_interval' is not set 732 - allow different update intervals for each STA 733 * fixed event loop to call signal handlers only after returning from 734 the real signal handler 735 * reset sta->timeout_next after successful association to make sure 736 that the previously registered inactivity timer will not remove the 737 STA immediately (e.g., if STA deauthenticates and re-associates 738 before the timer is triggered). 739 * added new hostapd.conf variable, nas_identifier, that can be used to 740 add an optional RADIUS Attribute, NAS-Identifier, into authentication 741 and accounting messages 742 * added support for Accounting-On and Accounting-Off messages 743 * fixed accounting session handling to send Accounting-Start only once 744 per session and not to send Accounting-Stop if the session was not 745 initialized properly 746 * fixed Accounting-Stop statistics in cases where the message was 747 previously sent after the kernel entry for the STA (and/or IEEE 748 802.1X data) was removed 749 750 751 Note: 752 753 Older changes up to and including v0.1.0 are included in the ChangeLog 754 of the Host AP driver. 755
