Some highlights from NEWS: ** Added OpenSSL 3.0 compatibility. ** Removed OpenSSL 1.0 compatibility. ** Support for FIDO 2.1 "minPinLength" extension. ** Support for COSE_EDDSA, COSE_ES256, and COSE_RS1 attestation. ** Support for TPM 2.0 attestation. ** Support for device timeouts; see fido_dev_set_timeout(). ** New API calls: - es256_pk_from_EVP_PKEY; - fido_cred_attstmt_len; - fido_cred_attstmt_ptr; - fido_cred_pin_minlen; - fido_cred_set_attstmt; - fido_cred_set_pin_minlen; - fido_dev_set_pin_minlen_rpid; - fido_dev_set_timeout; - rs256_pk_from_EVP_PKEY. ** Reliability and portability fixes. ** Better handling of HID devices without identification strings; gh#381.

* As of LLVM 10.0.0, MSAN support in libFuzzer was still experimental.
|
|
* We therefore have to be careful when using our custom mutator, or
|
|
* MSAN will flag uninitialised reads on memory populated by libFuzzer.
|
|
* Since there is no way to suppress MSAN without regenerating object
|
|
* code (in which case you might as well rebuild libFuzzer with MSAN),
|
|
* we adjust our mutator to make it less accurate while allowing
|
|
* fuzzing to proceed.
