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