This commit add following crypto changes
1. Update current crypto code with upstream supplicant code
2. Add a proper porting layer to use mbedtls APIs for all the crypto
operations used by supplicant.
Internal crypto will be used when USE_MBEDLTS flag is disabled
in supplicant's menuconfig.
This commit also removes the clutter in crypto files due to partial
porting of some APIs to mbedtls, all the code from those files have
been removed and rewritten in a generic way, this is inspired from
current upstream code.
This also reduces the lib size significantly, supplicant's lib
size reduces around ~567kb after this change(NB: lib size doesn't
indicate reduction in final bin size).
1. Add Example for DPP Enrollee
2. Use DPP Supplicant API's to setup connection
3. Add support for multiple channels in Bootstrapping
4. Add Unity testcase for testing Offchannel operations
Closes https://github.com/espressif/esp-idf/issues/5654
1. Modify DPP Protocol modules for our purpose
2. Add DPP supplicant task and modules to handle DPP frames
3. Add DPP Public API's and definitions for DPP
1. Add API's and structures for Remain-onChannel & Action Tx
2. Handling of events and callbacks for the operations
3. Update WiFi lib with related API support
Lock is not required during btm/rrm action frames processing and
taking it may cause inconsistant behavior since wifi task
posts the events to this task.
Flag ESP32_WIFI_ENABLE_WPA3_SAE from Menuconfig is used to
control the stack size required by WPA3. Use the same flag
to compile out the WPA3 code and control the code size.
With this flag disabled code footprint reduces by about 7.7kB
in libwpa_supplicant.a
Update WiFi libs with added checks to cleanly handle disabling
of WPA3 callbacks.

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.
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
longer signed/unsigned int).
Changes come from internal branch commit a6723fc
For WPA3 connection nearing PMK lifetime expiry, PMK Cache
needs a re-authentication or the cache will expire. After
current expiry of 12 hours Station ends up sending a deauth
to the AP. An SAE re-authentication also cannot occur without
a disconnection with current implementation. So increase the
PMK lifetime to 100 days for now.
1. Add STA checks during STA PMF operations
2. Fix WPA2-Ent issue with Open AP
3. Skip WPA-TKIP profile if PMF is required
4. Skip & clear Supplicant PMK Cache with mismatching AP config
* changing dependencies from unity->cmock
* added component.mk and Makefile.projbuild
* ignore test dir in gen_esp_err_to_name.py
* added some brief introduction of CMock in IDF
H/W decryption of Mgmt frames was disabled for PMF and done through
S/W. If ESPNOW packets go through this path, it affects backward
compatibility since method of decrypting Mgmt packets is different in H/W.
To address PMF + ESPNOW Co-existance, CCMP decryption method is modified
for ESPNOW packets so that they can be decrypted correctly. Since Tx
of ESPNOW packets can still be done in H/W alongside PMF, no change
required in encryption method in S/W.

wpa_supplicant: add support for PAP, MS-CHAP and CHAP as Phase 2 algorithms for TTLS alongside MS-CHAPv2
Closes FCS-361

Add following changes as part of this:
1. EAP client will crash during validation of key size when CA
certs and keys not present. Add changes to validate it first.
2. Free memory allocated in TLS context
1. If Device is connected to AP in WPA3-PSK mode, AP switching
security to WPA2-PSK causes connection failures even after reset.
Fix is to not store WPA3's PMK in NVS for caching.
2. AP switching back to WPA3 causes even more connection failures.
This is due to device not clearing Supplicant level PMK Cache when
it is no longer valid. Fix is to clear the Cache when 4-way handshake
fails and to check Key Mgmt of Cache before using.
3. When AP switches from WPA3 to WPA2, device's PMF config in
Supplicant remains enabled. This may cause failures during
4-way handshake. So clear PMF config in when PMF is no longer used.
WPS can send multiple AP credentials, while existing implementation
will only use the first credentials which could be for the 5G band.
Fix this by passing these credentials to the App and attempting
to connect using each of those. Older Apps will remain compatible
without breaking WPS, but the issue will remain.
Curretly wpa_supplicant uses internal APIs for RSA operations
which internally uses lots of big num operations.
Big num operations are CPU expensive and can take a lot of time
which can cause watchdog timer to tigger.
This can be optimize by using mbedtls APIs which uses
hardware blocks for big num operations.
To fix this, write new crypto_mbedtls-rsa.c which has APIs
similar to crypto_internal-rsa.c but uses mbedtls APIs.
