This commit adds different features from 802.11k and 802.11v
specifications to make the device ready for network assisted
roaming. It also adds initial framework for device to detect
whether it needs to move to a better AP.
Followings are added as part of this.
1. Support for sending neighbor report request and provide
the report back to the APP.
2. Support for beacon measurement report.
3. Support for link measurement report.
4. Support for sending bss transition management query frame
(triggered by the APP).
5. Support for bss transition management request and move
to the candidate based on that.
6. Sending the bss transition management response.
Add files required for DPP feature from upstream.
These file expose the functionality to create DPP packets.
Ported crypto layer from openssl to mbedtls.
Interfacing to use these API will be added in seperate commit
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
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
* Move smartconfig to its component directory, it should be possible to override
this as whole component
* Fix few header includes related to lwIP networking stack
