1To do:
2- hostap: try other roaming modes
3  NOTE: current mode (manual roaming) does not really roam at all..
4  Firmware did not notice the current AP disappearing..
5- add support for WPA with ap_scan=0 (update selected cipher etc. based on
6  AssocInfo; make sure these match with configuration)
7- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
8  authentication has been completed (cache scard data based on serial#(?)
9  and try to optimize next connection if the same card is present for next
10  auth)
11- on disconnect event, could try to associate with another AP if one is
12  present in scan results; would need to update scan results periodically..
13- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
14  ssid->proto fields to avoid detecting downgrade attacks when the driver
15  is not reporting RSN IE, but msg 3/4 has one
16- Cisco AP and non-zero keyidx for unicast -> map to broadcast
17  (actually, this already works with driver_ndis; so maybe just change
18  driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
19  for unicast); worked also with Host AP driver and madwifi
20- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
21  to see unencrypted EAPOL-Key frames at all..
22- EAP-PAX with PAX_SEC
23- EAP (RFC 3748)
24  * OTP Extended Responses (Sect. 5.5)
25- test what happens if authenticator sends EAP-Success before real EAP
26  authentication ("canned" Success); this should be ignored based on
27  RFC 3748 Sect. 4.2
28- test compilation with gcc -W options (more warnings?)
29  (Done once; number of unused function arguments still present)
30- add proper support for using dot11RSNAConfigSATimeout
31- ctrl_iface: get/set/remove blob
32- use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
33  web pages including the same information.. i.e., have this information only
34  in one page; how to build a PDF file with all the SGML included?
35- EAP-POTP/RSA SecurID profile (RFC 4793)
36- document wpa_gui build and consider adding it to 'make install'
37- test madwifi with pairwise=TKIP group=WEP104
38- possibility to link in WPA Authenticator state machine to wpa_supplicant
39  (new PeerKey handshake, WPA2/IEEE 802.11 (RSN) IBSS)
40- consider merging hostapd and wpa_supplicant PMKSA cache implementations
41- consider redesigning pending EAP requests (identity/password/otp from
42  ctrl_iface) by moving the retrying of the previous request into EAP
43  state machine so that EAPOL state machine is not needed for this
44- rfc4284.txt (network selection for eap)
45- www pages about configuring wpa_supplicant:
46  * global options (ap_scan, ctrl_interfaces) based on OS/driver
47  * network block
48  * key_mgmt selection
49  * WPA parameters
50  * EAP options (one page for each method)
51  * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
52    generate example configuration
53- error path in rsn_preauth_init: should probably deinit l2_packet handlers
54  if something fails; does something else need deinit?
55- consider moving SIM card functionality (IMSI fetching) away from eap.c;
56  this should likely happen before EAP is initialized for authentication;
57  now IMSI is read only after receiving EAP-Identity/Request, but since it is
58  really needed for all cases, reading IMSI and generating Identity string
59  could very well be done before EAP has been started
60- try to work around race in receiving association event and first EAPOL
61  message
62- add wpa_secure_memzero() macro and secure implementation (volatile u8*) to
63  clear memory; this would be used to clear temporary buffers containing
64  private data (e.g., keys); the macro can be defined to NOP in order to save
65  space (i.e., no code should depend on the macro doing something)
66- make sure that TLS session cache is not shared between EAP types or if it
67  is, that the cache entries are bound to only one EAP type; e.g., cache entry
68  created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
69- consider moving eap_tls_build_ack() call into eap_tls_process_helper()
70  (it seems to be called always if helper returns 1)
71  * could need to modify eap_{ttls,peap,fast}_decrypt to do same
72- add support for fetching full user cert chain from Windows certificate
73  stores even when there are intermediate CA certs that are not in the
74  configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
75
76
770.6.x branch:
78- clean up common.[ch]
79- change TLS/crypto library interface to use a structure of function
80  pointers and helper inline functions (like driver_ops) instead of
81  requiring every TLS wrapper to implement all functions
82- add support for encrypted configuration fields (e.g., password, psk,
83  passphrase, pin)
84- wpa_gui: add support for setting and showing priority, auth_alg
85  (open/shared for static WEP)
86
87- cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
88  phases should be able to use the same functions for this;
89  the last step in processing sent should be this code and rest of the code
90  should not need to care about fragmentation at all
91- test EAP-FAST peer with OpenSSL and verify that fallback to full handshake
92  (ServerHello followed by something else than ChangeCipherSpec)
