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

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.

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
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
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.

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
97 * Android: Add build and runtime support for Android hostapd.
98 * Add a new debug message level for excessive information. Use
100 * TLS: Add support for tls_disable_time_checks=1 in client mode.

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.

113 * bsd: Cleaned up driver wrapper and added various low-level
114 configuration options
115 * TNC: fixed issues with fragmentation

135 driver wrappers that use hostapd MLME (e.g., nl80211)
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
144 * fixed HT Capabilities IE with nl80211 drivers
145 * moved generic AP functionality code into src/ap

156 * fixed WPS Probe Request processing to handle missing required
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
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

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

193 or modify primary/secondary channels if needed based on neighboring
195 * added support for NFC out-of-band mechanism with WPS
196 * added preliminary support for IEEE 802.11r RIC processing
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
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
214 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
215 * added support for using driver_test over UDP socket

218 * fixed retransmission of EAP requests if no response is received
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
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
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
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
244 * fixed internal TLSv1 implementation for abbreviated handshake (used
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
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
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)
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)
278 * added support for opportunistic key caching (OKC)
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
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
296 * fixed EAP-SIM Start response processing for fast reauthentication
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
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
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,
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
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
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
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
363 * RADIUS server: added support for processing duplicate messages
364 (retransmissions from RADIUS client) by replying with the previous
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
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
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
392 * fixed session timeout processing with drivers that do not use
393 ieee802_11.c (e.g., madwifi)
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
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
403 * added support for RADIUS Authentication Server MIB (RFC 2619)
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]
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
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
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
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
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)
450 * added ap_max_inactivity configuration parameter
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)
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
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
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
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
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
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)
510 * fixed build without CONFIG_RSN_PREAUTH
511 * fixed FreeBSD build
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
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
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
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
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])
571 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
574 * added support for configuring a forced PEAP version based on the
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
580 * clear accounting data in the driver when starting a new accounting
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
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)
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
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
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)
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
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
655 * fixed RADIUS reconnection after an error in sending interim
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
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
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
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
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
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
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
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)
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
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
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
753 Older changes up to and including v0.1.0 are included in the ChangeLog
754 of the Host AP driver.
