Added WPA3 Testcases support for -
1. Anti-Clogging Token Request support
2. Return correct status from SAE modules for invalid scenarios
3. Add PMK Caching support for WPA3
wifi lib includes fixes for below PMF Certification issues -
1. Check return status of decrypt operation. Fixes 5.3.3.1.
2. Allow PMF negotiation for WPA2-Enterprise. Fixes 5.3.3.2, 5.3.3.4.
3. Add NULL check on key before encrypting PMF, fixes crash.
1) Added PMK caching module from wpa_supplicant.
2) Modified wpa_sm to
a) Add entry to PMK cache when first time associated to an AP.
b) Maintain entry across the associations.
c) Clear current PMKSA when deauth happens.
d) Search for an entry when re-associating to the same AP and
set it as current PMKSA
e) Wait for msg 1/4 from AP instead of starting EAP authentication.
f) Check PMKID in msg 1 with current PMKSA/cache.
g) Use the cached PMK to complete 4-way handshake.
3) Remove config_bss callback as it was redundant and used to cause
problems for PMK caching flow.
Closes IDF-969
A lot of internally used crypto headers are publicly includeable
in user projects. This leads to bug reports when these headers
are incorrectly used or the API's are not used as intended.
Move all crypto headers into private crypto src folder, also move
crypto_ops into Supplicant to remove dependecy on crypto headers.
Closes IDF-476
wpa_supplicant is using MbedTLS API's for crypto algorithms. For
calling them a duplicate set of modules is maintained prepended
with 'fast_'. Remove these and use flag USE_MBEDTLS_CRYPTO
instead to separate modules calling MbedTLS API's from native
implementation.
Move supplicant to idf and do following refactoring:
1. Make the folder structure consitent with supplicant upstream
2. Remove duplicated header files and minimize the public header files
3. Refactor for WiFi/supplicant interfaces
1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
1. Fix the WiFi/BT coexist bug
2. Fix WPA2 enterprise example crash bug
3. Add size and version check for crypto type struct
4. Add MD5 check for crypto type header file
