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