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.
In case of wrong passpharse, AP will keep on sending 1/4 multiple
times which may take around 10 secs to disconnect and detect
wrong password event.
Add changes to reject EAPOL1 after 3 consecutive reception
Some AP's keep NULL-padding at the end of some variable length WPS
Attributes. This is not as par the WPS2.0 specs, but to avoid interop
issues, ignore the padding by reducing the attribute length by 1.
1. Buffers for SAE messages are not freed after the handshake.
This causes memory leak, free buffers after SAE handshake.
2. SAE global data is not freed until the next WPA3 connection
takes place, holding up heap space without reason. Free this
data after SAE handshake is complete or event fails.
3. Update wifi lib which includes memory leak fix during BIP
encryption/decryption operations.
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
This is a regression from earlier commit related to TLSV12 which used
sha functions that are currently declared static.
Solution: Follow upstream code structure and resolve the errors.
Problem:
mbedtls_ctr_drbg_context was initialized in crypto_ec_point_mul. This
was okay in releases before 2.16.4 as entropy_len used to get set to
MBEDTLS_CTR_DRBG_ENTROPY_LEN in function mbedtls_ctr_drbg_seed. The
function is now changed to set the length to
MBEDTLS_CTR_DRBG_ENTROPY_LEN if previous length is 0 and hence the bug.
Solution:
Initialize mbedtls_ctr_drbg_context in crypto_ec_point_mul.
Activated AES, RSA and SHA hardware acceleration for esp32s2 and enabled related unit tests.
Updated with changes made for ESP32 from 0a04034, 961f59f and caea288.
Added performance targets for esp32s2beta
Closes IDF-757
1. Add changes in 4-way handshake path to allow SAE key mgmt.
2. Support for configuring WAP3 at init time, added Kconfig option.
3. Handle and propagate error conditions properly.
4. Link changes from WiFi library.
Under WPA3-Personal, SAE authentication is used to derive PMK
which is more secure and immune to offline dictionary attacks.
1. Add modules to generate SAE commit/confirm for the handshake
2. Add modules that build and parse SAE data in Auth frames
3. Add WPA3 association and key mgmt definitions
4. Invert y-bit while solving for ECC co-ordinate -
Once an X co-ordinate is obtained, solving for Y co-ordinate
using an elliptical curve equation results in 2 possible values,
Y and (P - Y), where p is the prime number. The co-ordinates are
used for deriving keys in SAE handshake. As par the 802.11 spec
if LSB of X is same as LSB of Y then Y is chosen, (P - Y) otherwise.
This is not what is implemented, so fix this behavior to obtain the
correct Y co-ordinate.
This change ports SAE(Simultaneous Authentication of Equals)
feature from wpa_supplicant and makes it work with mbedtls
crypto APIs. Currently only group 19 is supported. A sample
SAE handshake is included in the testcase. Other minor
changes for DH groups are also included.
1. Add CCMP, AES crypto modules for unicast protected Mgmt frames
2. Add support for computing SHA256 MIC on Bcast Mgmt frames
3. Add support for storing iGTK during 4-way handshake.
4. Provide APIs to MLME for utilizing the SW crypto modules
5. Link PMF changes from WiFi library submodule
1. Add APIs for configuring PMF through set config.
2. Map Supplicant and Wifi Cipher types.
3. Add support for PMF negotiation while generating RSN IE.
