  1. ChangeLog for hostapd
  2. ????-??-?? - v0.6.4
  3. * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
  4. Identity Request if identity is already known
  5. * added support for EAP Sequences in EAP-FAST Phase 2
  6. * added support for EAP-TNC (Trusted Network Connect)
  7. (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
  8. changes needed to run two methods in sequence (IF-T) and the IF-IMV
  9. and IF-TNCCS interfaces from TNCS)
  10. * added support for optional cryptobinding with PEAPv0
  11. 2008-02-22 - v0.6.3
  12. * fixed Reassociation Response callback processing when using internal
  13. MLME (driver_{hostap,nl80211,test}.c)
  14. * updated FT support to use the latest draft, IEEE 802.11r/D9.0
  15. * copy optional Proxy-State attributes into RADIUS response when acting
  16. as a RADIUS authentication server
  17. * fixed EAPOL state machine to handle a case in which no response is
  18. received from the RADIUS authentication server; previous version
  19. could have triggered a crash in some cases after a timeout
  20. * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
  21. be used
  22. * added a workaround for EAP-SIM/AKA peers that include incorrect null
  23. termination in the username
  24. * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
  25. attribute in notification messages only when using fast
  26. reauthentication
  27. * fixed EAP-SIM Start response processing for fast reauthentication
  28. case
  29. * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
  30. phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
  31. 2008-01-01 - v0.6.2
  32. * fixed EAP-SIM and EAP-AKA message parser to validate attribute
  33. lengths properly to avoid potential crash caused by invalid messages
  34. * added data structure for storing allocated buffers (struct wpabuf);
  35. this does not affect hostapd usage, but many of the APIs changed
  36. and various interfaces (e.g., EAP) is not compatible with old
  37. versions
  38. * added support for protecting EAP-AKA/Identity messages with
  39. AT_CHECKCODE (optional feature in RFC 4187)
  40. * added support for protected result indication with AT_RESULT_IND for
  41. EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
  42. * added support for configuring EAP-TTLS phase 2 non-EAP methods in
  43. EAP server configuration; previously all four were enabled for every
  44. phase 2 user, now all four are disabled by default and need to be
  45. enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
  46. TTLS-MSCHAPV2
  47. * removed old debug printing mechanism and the related 'debug'
  48. parameter in the configuration file; debug verbosity is now set with
  49. -d (or -dd) command line arguments
  50. * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
  51. only shared key/password authentication is supported in this version
  52. 2007-11-24 - v0.6.1
  53. * added experimental, integrated TLSv1 server implementation with the
  54. needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
  55. setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
  56. .config); this can be useful, e.g., if the target system does not
  57. have a suitable TLS library and a minimal code size is required
  58. * added support for EAP-FAST server method to the integrated EAP
  59. server
  60. * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
  61. draft (draft-ietf-emu-eap-gpsk-07.txt)
  62. * added a new configuration parameter, rsn_pairwise, to allow different
  63. pairwise cipher suites to be enabled for WPA and RSN/WPA2
  64. (note: if wpa_pairwise differs from rsn_pairwise, the driver will
  65. either need to support this or will have to use the WPA/RSN IEs from
  66. hostapd; currently, the included madwifi and bsd driver interfaces do
  67. not have support for this)
  68. * updated FT support to use the latest draft, IEEE 802.11r/D8.0
  69. 2007-05-28 - v0.6.0
  70. * added experimental IEEE 802.11r/D6.0 support
  71. * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
  72. * updated EAP-PSK to use the IANA-allocated EAP type 47
  73. * fixed EAP-PSK bit ordering of the Flags field
  74. * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
  75. by reading wpa_psk_file [Bug 181]
  76. * fixed EAP-TTLS AVP parser processing for too short AVP lengths
  77. * fixed IPv6 connection to RADIUS accounting server
  78. * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
  79. draft (draft-ietf-emu-eap-gpsk-04.txt)
  80. * hlr_auc_gw: read GSM triplet file into memory and rotate through the
  81. entries instead of only using the same three triplets every time
  82. (this does not work properly with tests using multiple clients, but
  83. provides bit better triplet data for testing a single client; anyway,
  84. if a better quality triplets are needed, GSM-Milenage should be used
  85. instead of hardcoded triplet file)
  86. * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
  87. in Success Request [Bug 203]
  88. * added support for sending EAP-AKA Notifications in error cases
  89. * updated to use IEEE 802.11w/D2.0 for management frame protection
  90. (still experimental)
  91. * RADIUS server: added support for processing duplicate messages
  92. (retransmissions from RADIUS client) by replying with the previous
  93. reply
  94. 2006-11-24 - v0.5.6
  95. * added support for configuring and controlling multiple BSSes per
  96. radio interface (bss=<ifname> in hostapd.conf); this is only
  97. available with Devicescape and test driver interfaces
  98. * fixed PMKSA cache update in the end of successful RSN
  99. pre-authentication
  100. * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
  101. for each STA based on RADIUS Access-Accept attributes); this requires
  102. VLAN support from the kernel driver/802.11 stack and this is
  103. currently only available with Devicescape and test driver interfaces
  104. * driver_madwifi: fixed configuration of unencrypted modes (plaintext
  105. and IEEE 802.1X without WEP)
  106. * removed STAKey handshake since PeerKey handshake has replaced it in
  107. IEEE 802.11ma and there are no known deployments of STAKey
  108. * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
  109. draft (draft-ietf-emu-eap-gpsk-01.txt)
  110. * added preliminary implementation of IEEE 802.11w/D1.0 (management
  111. frame protection)
  112. (Note: this requires driver support to work properly.)
  113. (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
  114. * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
  115. * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
  116. parameters from a text file to make it possible to implement proper
  117. GSM/UMTS authentication server for multiple SIM/USIM cards using
  118. EAP-SIM/EAP-AKA
  119. * fixed session timeout processing with drivers that do not use
  120. ieee802_11.c (e.g., madwifi)
  121. 2006-08-27 - v0.5.5
  122. * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
  123. hostapd (e.g., to initialize wired network authentication based on an
  124. external signal)
  125. * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
  126. using WPA2 even if PMKSA caching is not used
  127. * added -P<pid file> argument for hostapd to write the current process
  128. id into a file
  129. * added support for RADIUS Authentication Server MIB (RFC 2619)
  130. 2006-06-20 - v0.5.4
  131. * fixed nt_password_hash build [Bug 144]
  132. * added PeerKey handshake implementation for IEEE 802.11e
  133. direct link setup (DLS) to replace STAKey handshake
  134. * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
  135. draft-clancy-emu-eap-shared-secret-00.txt)
  136. * fixed a segmentation fault when RSN pre-authentication was completed
  137. successfully [Bug 152]
  138. 2006-04-27 - v0.5.3
  139. * do not build nt_password_hash and hlr_auc_gw by default to avoid
  140. requiring a TLS library for a successful build; these programs can be
  141. build with 'make nt_password_hash' and 'make hlr_auc_gw'
  142. * added a new configuration option, eapol_version, that can be used to
  143. set EAPOL version to 1 (default is 2) to work around broken client
  144. implementations that drop EAPOL frames which use version number 2
  145. [Bug 89]
  146. * added support for EAP-SAKE (no EAP method number allocated yet, so
  147. this is using the same experimental type 255 as EAP-PSK)
  148. * fixed EAP-MSCHAPv2 message length validation
  149. 2006-03-19 - v0.5.2
  150. * fixed stdarg use in hostapd_logger(): if both stdout and syslog
  151. logging was enabled, hostapd could trigger a segmentation fault in
  152. vsyslog on some CPU -- C library combinations
  153. * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
  154. program to make it easier to use for implementing real SS7 gateway;
  155. eap_sim_db is not anymore used as a file name for GSM authentication
  156. triplets; instead, it is path to UNIX domain socket that will be used
  157. to communicate with the external gateway program (e.g., hlr_auc_gw)
  158. * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
  159. local information (GSM authentication triplets from a text file and
  160. hardcoded AKA authentication data); this can be used to test EAP-SIM
  161. and EAP-AKA
  162. * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
  163. to make it possible to test EAP-AKA with real USIM cards (this is
  164. disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
  165. to enable this)
  166. * driver_madwifi: added support for getting station RSN IE from
  167. madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
  168. broken with earlier change (r1357) in the driver
  169. * changed EAP method registration to use a dynamic list of methods
  170. instead of a static list generated at build time
  171. * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
  172. [Bug 125]
  173. * added ap_max_inactivity configuration parameter
  174. 2006-01-29 - v0.5.1
  175. * driver_test: added better support for multiple APs and STAs by using
  176. a directory with sockets that include MAC address for each device in
  177. the name (test_socket=DIR:/tmp/test)
  178. * added support for EAP expanded type (vendor specific EAP methods)
  179. 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
  180. * added experimental STAKey handshake implementation for IEEE 802.11e
  181. direct link setup (DLS); note: this is disabled by default in both
  182. build and runtime configuration (can be enabled with CONFIG_STAKEY=y
  183. and stakey=1)
  184. * added support for EAP methods to use callbacks to external programs
  185. by buffering a pending request and processing it after the EAP method
  186. is ready to continue
  187. * improved EAP-SIM database interface to allow external request to GSM
  188. HLR/AuC without blocking hostapd process
  189. * added support for using EAP-SIM pseudonyms and fast re-authentication
  190. * added support for EAP-AKA in the integrated EAP authenticator
  191. * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
  192. user database to allow EAP-SIM/AKA selection without extra roundtrip
  193. for EAP-Nak negotiation
  194. * added support for storing EAP user password as NtPasswordHash instead
  195. of plaintext password when using MSCHAP or MSCHAPv2 for
  196. authentication (hash:<16-octet hex value>); added nt_password_hash
  197. tool for hashing password to generate NtPasswordHash
  198. 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
  199. * driver_wired: fixed EAPOL sending to optionally use PAE group address
  200. as the destination instead of supplicant MAC address; this is
  201. disabled by default, but should be enabled with use_pae_group_addr=1
  202. in configuration file if the wired interface is used by only one
  203. device at the time (common switch configuration)
  204. * driver_madwifi: configure driver to use TKIP countermeasures in order
  205. to get correct behavior (IEEE 802.11 association failing; previously,
  206. association succeeded, but hostpad forced disassociation immediately)
  207. * driver_madwifi: added support for madwifi-ng
  208. 2005-10-27 - v0.4.6
  209. * added support for replacing user identity from EAP with RADIUS
  210. User-Name attribute from Access-Accept message, if that is included,
  211. for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
  212. tunneled identity into accounting messages when the RADIUS server
  213. does not support better way of doing this with Class attribute)
  214. * driver_madwifi: fixed EAPOL packet receive for configuration where
  215. ath# is part of a bridge interface
  216. * added a configuration file and log analyzer script for logwatch
  217. * fixed EAPOL state machine step function to process all state
  218. transitions before processing new events; this resolves a race
  219. condition in which EAPOL-Start message could trigger hostapd to send
  220. two EAP-Response/Identity frames to the authentication server
  221. 2005-09-25 - v0.4.5
  222. * added client CA list to the TLS certificate request in order to make
  223. it easier for the client to select which certificate to use
  224. * added experimental support for EAP-PSK
  225. * added support for WE-19 (hostap, madwifi)
  226. 2005-08-21 - v0.4.4
  227. * fixed build without CONFIG_RSN_PREAUTH
  228. * fixed FreeBSD build
  229. 2005-06-26 - v0.4.3
  230. * fixed PMKSA caching to copy User-Name and Class attributes so that
  231. RADIUS accounting gets correct information
  232. * start RADIUS accounting only after successful completion of WPA
  233. 4-Way Handshake if WPA-PSK is used
  234. * fixed PMKSA caching for the case where STA (re)associates without
  235. first disassociating
  236. 2005-06-12 - v0.4.2
  237. * EAP-PAX is now registered as EAP type 46
  238. * fixed EAP-PAX MAC calculation
  239. * fixed EAP-PAX CK and ICK key derivation
  240. * renamed eap_authenticator configuration variable to eap_server to
  241. better match with RFC 3748 (EAP) terminology
  242. * driver_test: added support for testing hostapd with wpa_supplicant
  243. by using test driver interface without any kernel drivers or network
  244. cards
  245. 2005-05-22 - v0.4.1
  246. * fixed RADIUS server initialization when only auth or acct server
  247. is configured and the other one is left empty
  248. * driver_madwifi: added support for RADIUS accounting
  249. * driver_madwifi: added preliminary support for compiling against 'BSD'
  250. branch of madwifi CVS tree
  251. * driver_madwifi: fixed pairwise key removal to allow WPA reauth
  252. without disassociation
  253. * added support for reading additional certificates from PKCS#12 files
  254. and adding them to the certificate chain
  255. * fixed RADIUS Class attribute processing to only use Access-Accept
  256. packets to update Class; previously, other RADIUS authentication
  257. packets could have cleared Class attribute
  258. * added support for more than one Class attribute in RADIUS packets
  259. * added support for verifying certificate revocation list (CRL) when
  260. using integrated EAP authenticator for EAP-TLS; new hostapd.conf
  261. options 'check_crl'; CRL must be included in the ca_cert file for now
  262. 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
  263. * added support for including network information into
  264. EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
  265. (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
  266. * fixed a bug which caused some RSN pre-authentication cases to use
  267. freed memory and potentially crash hostapd
  268. * fixed private key loading for cases where passphrase is not set
  269. * added support for sending TLS alerts and aborting authentication
  270. when receiving a TLS alert
  271. * fixed WPA2 to add PMKSA cache entry when using integrated EAP
  272. authenticator
  273. * fixed PMKSA caching (EAP authentication was not skipped correctly
  274. with the new state machine changes from IEEE 802.1X draft)
  275. * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
  276. and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
  277. to be added to .config to include IPv6 support); for RADIUS server,
  278. radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
  279. in RADIUS clients file can then use IPv6 format
  280. * added experimental support for EAP-PAX
  281. * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
  282. the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
  283. 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
  284. 2005-01-23 - v0.3.5
  285. * added support for configuring a forced PEAP version based on the
  286. Phase 1 identity
  287. * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
  288. to terminate authentication
  289. * fixed EAP identifier duplicate processing with the new IEEE 802.1X
  290. draft
  291. * clear accounting data in the driver when starting a new accounting
  292. session
  293. * driver_madwifi: filter wireless events based on ifindex to allow more
  294. than one network interface to be used
  295. * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
  296. setting if the packet does not pass MIC verification (e.g., due to
  297. incorrect PSK); previously, message 1/4 was not tried again if an
  298. invalid message 2/4 was received
  299. * fixed reconfiguration of RADIUS client retransmission timer when
  300. adding a new message to the pending list; previously, timer was not
  301. updated at this point and if there was a pending message with long
  302. time for the next retry, the new message needed to wait that long for
  303. its first retry, too
  304. 2005-01-09 - v0.3.4
  305. * added support for configuring multiple allowed EAP types for Phase 2
  306. authentication (EAP-PEAP, EAP-TTLS)
  307. * fixed EAPOL-Start processing to trigger WPA reauthentication
  308. (previously, only EAPOL authentication was done)
  309. 2005-01-02 - v0.3.3
  310. * added support for EAP-PEAP in the integrated EAP authenticator
  311. * added support for EAP-GTC in the integrated EAP authenticator
  312. * added support for configuring list of EAP methods for Phase 1 so that
  313. the integrated EAP authenticator can, e.g., use the wildcard entry
  314. for EAP-TLS and EAP-PEAP
  315. * added support for EAP-TTLS in the integrated EAP authenticator
  316. * added support for EAP-SIM in the integrated EAP authenticator
  317. * added support for using hostapd as a RADIUS authentication server
  318. with the integrated EAP authenticator taking care of EAP
  319. authentication (new hostapd.conf options: radius_server_clients and
  320. radius_server_auth_port); this is not included in default build; use
  321. CONFIG_RADIUS_SERVER=y in .config to include
  322. 2004-12-19 - v0.3.2
  323. * removed 'daemonize' configuration file option since it has not really
  324. been used at all for more than year
  325. * driver_madwifi: fixed group key setup and added get_ssid method
  326. * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
  327. 2004-12-12 - v0.3.1
  328. * added support for integrated EAP-TLS authentication (new hostapd.conf
  329. variables: ca_cert, server_cert, private_key, private_key_passwd);
  330. this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
  331. external RADIUS server
  332. * added support for reading PKCS#12 (PFX) files (as a replacement for
  333. PEM/DER) to get certificate and private key (CONFIG_PKCS12)
  334. 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
  335. * added support for Acct-{Input,Output}-Gigawords
  336. * added support for Event-Timestamp (in RADIUS Accounting-Requests)
  337. * added support for RADIUS Authentication Client MIB (RFC2618)
  338. * added support for RADIUS Accounting Client MIB (RFC2620)
  339. * made EAP re-authentication period configurable (eap_reauth_period)
  340. * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
  341. * fixed EAPOL state machine to stop if STA is removed during
  342. eapol_sm_step(); this fixes at least one segfault triggering bug with
  343. IEEE 802.11i pre-authentication
  344. * added support for multiple WPA pre-shared keys (e.g., one for each
  345. client MAC address or keys shared by a group of clients);
  346. new hostapd.conf field wpa_psk_file for setting path to a text file
  347. containing PSKs, see hostapd.wpa_psk for an example
  348. * added support for multiple driver interfaces to allow hostapd to be
  349. used with other drivers
  350. * added wired authenticator driver interface (driver=wired in
  351. hostapd.conf, see wired.conf for example configuration)
  352. * added madwifi driver interface (driver=madwifi in hostapd.conf, see
  353. madwifi.conf for example configuration; Note: include files from
  354. madwifi project is needed for building and a configuration file,
  355. .config, needs to be created in hostapd directory with
  356. CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
  357. build)
  358. * fixed an alignment issue that could cause SHA-1 to fail on some
  359. platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
  360. align variables)
  361. * fixed RADIUS reconnection after an error in sending interim
  362. accounting packets
  363. * added hostapd control interface for external programs and an example
  364. CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
  365. * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
  366. 'hostapd_cli sta <addr>')
  367. * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
  368. * added support for strict GTK rekeying (wpa_strict_rekey in
  369. hostapd.conf)
  370. * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
  371. (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
  372. IEEE 802.11F-2003)
  373. * added Prism54 driver interface (driver=prism54 in hostapd.conf;
  374. note: .config needs to be created in hostapd directory with
  375. CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
  376. build)
  377. * dual-licensed hostapd (GPLv2 and BSD licenses)
  378. * fixed RADIUS accounting to generate a new session id for cases where
  379. a station reassociates without first being complete deauthenticated
  380. * fixed STA disassociation handler to mark next timeout state to
  381. deauthenticate the station, i.e., skip long wait for inactivity poll
  382. and extra disassociation, if the STA disassociates without
  383. deauthenticating
  384. * added integrated EAP authenticator that can be used instead of
  385. external RADIUS authentication server; currently, only EAP-MD5 is
  386. supported, so this cannot yet be used for key distribution; the EAP
  387. method interface is generic, though, so adding new EAP methods should
  388. be straightforward; new hostapd.conf variables: 'eap_authenticator'
  389. and 'eap_user_file'; this obsoletes "minimal authentication server"
  390. ('minimal_eap' in hostapd.conf) which is now removed
  391. * added support for FreeBSD and driver interface for the BSD net80211
  392. layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
  393. .config); please note that some of the required kernel mods have not
  394. yet been committed
  395. 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
  396. * fixed some accounting cases where Accounting-Start was sent when
  397. IEEE 802.1X port was being deauthorized
  398. 2004-06-20 - v0.2.3
  399. * modified RADIUS client to re-connect the socket in case of certain
  400. error codes that are generated when a network interface state is
  401. changes (e.g., when IP address changes or the interface is set UP)
  402. * fixed couple of cases where EAPOL state for a station was freed
  403. twice causing a segfault for hostapd
  404. * fixed couple of bugs in processing WPA deauthentication (freed data
  405. was used)
  406. 2004-05-31 - v0.2.2
  407. * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
  408. * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
  409. cases where STAs dropped multicast frames as replay attacks
  410. * added support for copying RADIUS Attribute 'Class' from
  411. authentication messages into accounting messages
  412. * send canned EAP failure if RADIUS server sends Access-Reject without
  413. EAP message (previously, Supplicant was not notified in this case)
  414. * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
  415. not start EAPOL state machines if the STA selected to use WPA-PSK)
  416. 2004-05-06 - v0.2.1
  417. * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
  418. - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
  419. (i.e., IEEE 802.11i/D3.0)
  420. - supports WPA-only, RSN-only, and mixed WPA/RSN mode
  421. - both WPA-PSK and WPA-RADIUS/EAP are supported
  422. - PMKSA caching and pre-authentication
  423. - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
  424. wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
  425. rsn_preauth, rsn_preauth_interfaces
  426. * fixed interim accounting to remove any pending accounting messages
  427. to the STA before sending a new one
  428. 2004-02-15 - v0.2.0
  429. * added support for Acct-Interim-Interval:
  430. - draft-ietf-radius-acct-interim-01.txt
  431. - use Acct-Interim-Interval attribute from Access-Accept if local
  432. 'radius_acct_interim_interval' is not set
  433. - allow different update intervals for each STA
  434. * fixed event loop to call signal handlers only after returning from
  435. the real signal handler
  436. * reset sta->timeout_next after successful association to make sure
  437. that the previously registered inactivity timer will not remove the
  438. STA immediately (e.g., if STA deauthenticates and re-associates
  439. before the timer is triggered).
  440. * added new hostapd.conf variable, nas_identifier, that can be used to
  441. add an optional RADIUS Attribute, NAS-Identifier, into authentication
  442. and accounting messages
  443. * added support for Accounting-On and Accounting-Off messages
  444. * fixed accounting session handling to send Accounting-Start only once
  445. per session and not to send Accounting-Stop if the session was not
  446. initialized properly
  447. * fixed Accounting-Stop statistics in cases where the message was
  448. previously sent after the kernel entry for the STA (and/or IEEE
  449. 802.1X data) was removed
  450. Note:
  451. Older changes up to and including v0.1.0 are included in the ChangeLog
  452. of the Host AP driver.
