No point in using time with Host AP driver optimizations anymore. Note another race condition with 4-way handshake (and PTK config to driver).

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
|
|
- possibility to link in WPA Authenticator state machine to wpa_supplicant
|
|
(new PeerKey handshake, WPA2/IEEE 802.11 (RSN) IBSS)
|
|
- 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
|
