This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Supported the AEX (Asynchronous Enclave Exit) Notify feature. Supported Mbed-TLS Cryptography library (excluding SSL/TLS portion) in Enclave. Applied patches to OpenSSL 1.1.1t, fixed CVE-2023-1255, CVE-2023-0465 and CVE-2023-0466. Upgraded to Intel(R) Integrated Performance Primitives (IPP) Cryptography library version 2021.7. Upgraded Intel SGX Quote Verification Enclave to integrate updated SgxSSL. Enhanced the attestation local cache functionality by giving users the option to provide their own cache file. Enabled QPL/QCNL log in DCAP samples. Fixed bugs. Signed-off-by: Li, Xun <[email protected]>
