+To do:
+- hostap: try other roaming modes
+  NOTE: current mode (manual roaming) does not really roam at all..
+  Firmware did not notice the current AP disappearing..
+- add support for WPA with ap_scan=0 (update selected cipher etc. based on
+  AssocInfo; make sure these match with configuration)
+- optional security separation (build time option): run EAPOL state machines
+  as non-root (need to add something like socketpair between privileged root
+  process and non-root handler; send EAPOL packets between processes
+  and send keying data from non-root -> privileged)
+  EAPOL-Key processing (WPA & WEP keys) could be in privileged part
+  at least in the beginning; some parts might end up being moved to
+  non-root part eventually
+- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
+  authentication has been completed (cache scard data based on serial#(?)
+  and try to optimize next connection if the same card is present for next
+  auth)
+- EAP-AKA: AT_CHECKCODE
+- EAP-SIM/AKA: AT_RESULT_IND
+- on disconnect event, could try to associate with another AP if one is
+  present in scan results; would need to update scan results periodically..
+- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
+  ssid->proto fields to avoid detecting downgrade attacks when the driver
+  is not reporting RSN IE, but msg 3/4 has one
+- Cisco AP and non-zero keyidx for unicast -> map to broadcast
+  (actually, this already works with driver_ndis; so maybe just change
+  driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
+  for unicast); worked also with Host AP driver and madwifi
+- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
+  to see unencrypted EAPOL-Key frames at all..
+- EAP-PAX with PAX_SEC
+- EAP (RFC 3748)
+  * OTP Extended Responses (Sect. 5.5)
+- test what happens if authenticator sends EAP-Success before real EAP
+  authentication ("canned" Success); this should be ignored based on
+  RFC 3748 Sect. 4.2
+- test compilation with gcc -W options (more warnings?)
+  (Done once; number of unused function arguments still present)
+- add proper support for using dot11RSNAConfigSATimeout
+- ctrl_iface: get/set/remove blob
+- use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
+  web pages including the same information.. i.e., have this information only
+  in one page; how to build a PDF file with all the SGML included?
+- test wait-for-interface and daemonize combinations with number of driver
+  interfaces
+  * 'test' worked with WPA-PSK
+- EAP-POTP/RSA SecurID profile (draft-nystrom-eap-potp-03.txt)
+- document wpa_gui build and consider adding it to 'make install'
+- test madwifi with pairwise=TKIP group=WEP104
+- possibility to link in WPA Authenticator state machine to wpa_supplicant
+  (new STAKey handshake, WPA2 IBSS)
+- consider merging hostapd and wpa_supplicant PMKSA cache implementations
+- add support for configuring password for MSCHAPv2 as NtPasswordHash in
+  the same way as was added to hostapd (hash:<hex value>)
+- test_driver: configure directory and create AP-<mac> and STA-<mac> files
+  there to allow scanning multiple APs (e.g., for testing pre-auth and PMKSA
+  caching testing) and to exchange STA-STA EAPOL frames
+- consider adding generic buffer functionality that could be used in number
+  of places
+  * allocate buffer (with default max size), allow reserving head room to
+    make it possible to add a header without having to reallocate buffer
+  * reallocate buffer (add head and/or tail room)
+  * ref count and free when count=0 ?
+  * add data (to tail): re-alloc more tailroom if needed and copy new data
+  * error flag so that caller can do multiple add()s and only in the end
+    check whether something has failed; this should make error handling
+    simpler
+- consider redesigning pending EAP requests (identity/password/otp from
+  ctrl_iface) by moving the retrying of the previous request into EAP
+  state machine so that EAPOL state machine is not needed for this
+- rfc4284.txt (network selection for eap)
+- www pages about configuring wpa_supplicant:
+  * global options (ap_scan, ctrl_interfaces) based on OS/driver
+  * network block
+  * key_mgmt selection
+  * WPA parameters
+  * EAP options (one page for each method)
+  * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
+    generate example configuration
+- error path in rsn_preauth_init: should probably deinit l2_packet handlers
+  if something fails; does something else need deinit?
+- consider moving SIM card functionality (IMSI fetching) away from eap.c;
+  this should likely happen before EAP is initialized for authentication;
+  now IMSI is read only after receiving EAP-Identity/Request, but since it is
+  really needed for all cases, reading IMSI and generating Identity string
+  could very well be done before EAP has been started
+- test all allowed EAP Phase 2 methods (i.e., anything else than PEAP, TTLS,
+  FAST): SIM AKA PAX PSK LEAP; if these work, include in eap_testing.txt; if
+  not, either fix or make eap_allowed_phase2_type reject
+- try to work around race in receiving association event and first EAPOL
+  message
+- helper function to do memcmp(addr, "\x00\x00\x00\x00\x00\x00", ETH_ALEN)
+- add wpa_secure_memzero() macro and secure implementation (volatile u8*) to
+  clear memory; this would be used to clear temporary buffers containing
+  private data (e.g., keys); the macro can be defined to NOP in order to save
+  space (i.e., no code should depend on the macro doing something)
+- make sure that TLS session cache is not shared between EAP types or if it
+  is, that the cache entries are bound to only one EAP type; e.g., cache entry
+  created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
+- consider moving eap_tls_build_ack() call into eap_tls_process_helper()
+  (it seems to be called always if helper returns 1)
+  * could need to modify eap_{ttls,peap,fast}_decrypt to do same
+- add support for fetching full user cert chain from Windows certificate
+  stores even when there are intermediate CA certs that are not in the
+  configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
+
+
+0.6.x branch:
+- clean up common.[ch]
+- change TLS/crypto library interface to use a structure of function
+  pointers and helper inline functions (like driver_ops) instead of
+  requiring every TLS wrapper to implement all functions
+- move from CVS to git (0.3.x, 0.4.x, 0.5.x releases will continue
+  to be updated only on CVS)
+- move files into subdirectories and combine wpa_supplicant and hostapd
+  into a repository that matches in directory structure with the release
+  tarballs
+  (subdirs: eap_common, eap_peer, eap_server, driver, driver_ap, ...)
+- make it clearer that EAP server/peer can be used as a separate library
+  for other programs
+- add support for encrypted configuration fields (e.g., password, psk,
+  passphrase, pin)
+- wpa_gui: add support for setting and showing priority, id_str, auth_alg
+  (open/shared for static WEP)
