To do:
- add support for WPA with ap_scan=0 (update selected cipher etc. based on
AssocInfo; make sure these match with configuration)
- 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)
- 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?
- EAP-POTP/RSA SecurID profile (RFC 4793)
- document wpa_gui build and consider adding it to 'make install'
- test madwifi with pairwise=TKIP group=WEP104
- consider merging hostapd and wpa_supplicant PMKSA cache implementations
- 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
- try to work around race in receiving association event and first EAPOL
message
- try to work around race in configuring PTK and sending msg 4/4 (some NDIS
drivers with ndiswrapper end up not being able to complete 4-way handshake
in some cases; extra delay before setting the key seems to help)
- 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)
- 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
- add support for encrypted configuration fields (e.g., password, psk,
passphrase, pin)
- wpa_gui: add support for setting and showing priority
- cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
phases should be able to use the same functions for this;
the last step in processing sent should be this code and rest of the code
should not need to care about fragmentation at all
- test EAP-FAST peer with OpenSSL and verify that fallback to full handshake
(ServerHello followed by something else than ChangeCipherSpec)
