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