wpa_supplicant/todo.txt

   1 To do:
   2 - add support for WPA with ap_scan=0 (update selected cipher etc. based on
   3   AssocInfo; make sure these match with configuration)
   4 - consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
   5   authentication has been completed (cache scard data based on serial#(?)
   6   and try to optimize next connection if the same card is present for next
   7   auth)
   8 - if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
   9   ssid->proto fields to avoid detecting downgrade attacks when the driver
  10   is not reporting RSN IE, but msg 3/4 has one
  11 - Cisco AP and non-zero keyidx for unicast -> map to broadcast
  12   (actually, this already works with driver_ndis; so maybe just change
  13   driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
  14   for unicast); worked also with Host AP driver and madwifi
  15 - IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
  16   to see unencrypted EAPOL-Key frames at all..
  17 - EAP-PAX with PAX_SEC
  18 - EAP (RFC 3748)
  19   * OTP Extended Responses (Sect. 5.5)
  20 - test what happens if authenticator sends EAP-Success before real EAP
  21   authentication ("canned" Success); this should be ignored based on
  22   RFC 3748 Sect. 4.2
  23 - test compilation with gcc -W options (more warnings?)
  24   (Done once; number of unused function arguments still present)
  25 - ctrl_iface: get/remove blob
  26 - use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
  27   web pages including the same information.. i.e., have this information only
  28   in one page; how to build a PDF file with all the SGML included?
  29 - EAP-POTP/RSA SecurID profile (RFC 4793)
  30 - document wpa_gui build and consider adding it to 'make install'
  31 - consider merging hostapd and wpa_supplicant PMKSA cache implementations
  32 - consider redesigning pending EAP requests (identity/password/otp from
  33   ctrl_iface) by moving the retrying of the previous request into EAP
  34   state machine so that EAPOL state machine is not needed for this
  35 - rfc4284.txt (network selection for eap)
  36 - www pages about configuring wpa_supplicant:
  37   * global options (ap_scan, ctrl_interfaces) based on OS/driver
  38   * network block
  39   * key_mgmt selection
  40   * WPA parameters
  41   * EAP options (one page for each method)
  42   * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
  43     generate example configuration
  44 - error path in rsn_preauth_init: should probably deinit l2_packet handlers
  45   if something fails; does something else need deinit?
  46 - consider moving SIM card functionality (IMSI fetching) away from eap.c;
  47   this should likely happen before EAP is initialized for authentication;
  48   now IMSI is read only after receiving EAP-Identity/Request, but since it is
  49   really needed for all cases, reading IMSI and generating Identity string
  50   could very well be done before EAP has been started
  51 - try to work around race in receiving association event and first EAPOL
  52   message
  53 - try to work around race in configuring PTK and sending msg 4/4 (some NDIS
  54   drivers with ndiswrapper end up not being able to complete 4-way handshake
  55   in some cases; extra delay before setting the key seems to help)
  56 - make sure that TLS session cache is not shared between EAP types or if it
  57   is, that the cache entries are bound to only one EAP type; e.g., cache entry
  58   created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
  59 - consider moving eap_peer_tls_build_ack() call into
  60   eap_peer_tls_process_helper()
  61   (it seems to be called always if helper returns 1)
  62   * could need to modify eap_{ttls,peap,fast}_decrypt to do same
  63 - add support for fetching full user cert chain from Windows certificate
  64   stores even when there are intermediate CA certs that are not in the
  65   configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
  66 - clean up common.[ch]
  67 - change TLS/crypto library interface to use a structure of function
  68   pointers and helper inline functions (like driver_ops) instead of
  69   requiring every TLS wrapper to implement all functions
  70 - add support for encrypted configuration fields (e.g., password, psk,
  71   passphrase, pin)
  72 - wpa_gui: add support for setting and showing priority
  73 - cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
  74   phases should be able to use the same functions for this;
  75   the last step in processing sent should be this code and rest of the code
  76   should not need to care about fragmentation at all
  77 - test EAP-FAST peer with OpenSSL and verify that fallback to full handshake
  78   (ServerHello followed by something else than ChangeCipherSpec)
