1To 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)
