_oe_result oe_result_str oe_result_t

enum _oe_result This enumeration type defines return codes for Open Enclave functions. These functions return OE_OK upon success and one of the other enumeration values on failure. Enumerator OE_OK  The function was successful. OE_FAILURE  The function failed (without a more specific error code). OE_BUFFER_TOO_SMALL  One or more output buffer function parameters is too small. OE_INVALID_PARAMETER  One or more input function parameters is invalid. Either the value of an input parameter is invalid or a required input parameter pointer is null. OE_REENTRANT_ECALL  The host attempted to perform a reentrant ECALL. This occurs when an OCALL function attempts to perform an ECALL. OE_OUT_OF_MEMORY  The function is out of memory. This usually occurs when malloc or a related function returns null. OE_OUT_OF_THREADS  The function is unable to bind the current host thread to an enclave thread. This occurs when the host performs an ECALL while all enclave threads are in use. OE_UNEXPECTED  The function encountered an unexpected failure. OE_VERIFY_FAILED  A cryptographic verification failed. Examples include: enclave quote verification public key signature verification certificate chain verification OE_NOT_FOUND  The function failed to find a resource. Examples of resources include files, directories, and functions (ECALL/OCALL), container elements. OE_INTEGER_OVERFLOW  The function encountered an overflow in an integer operation, which can occur in arithmetic operations and cast operations. OE_PUBLIC_KEY_NOT_FOUND  The certificate does not contain a public key. OE_OUT_OF_BOUNDS  An integer index is outside the expected range. For example, an array index is greater than or equal to the array size. OE_OVERLAPPED_COPY  The function prevented an attempt to perform an overlapped copy, where the source and destination buffers are overlapping. OE_CONSTRAINT_FAILED  The function detected a constraint failure. A constraint restricts the the value of a field, parameter, or variable. For example, the value of day_of_the_week must be between 1 and 7 inclusive. OE_IOCTL_FAILED  An IOCTL operation failed. Open Enclave uses IOCTL operations to communicate with the Intel SGX driver. OE_UNSUPPORTED  The given operation is unsupported, usually by a particular platform or environment. OE_READ_FAILED  The function failed to read data from a device (such as a socket, or file). OE_SERVICE_UNAVAILABLE  A software service is unavailable (such as the AESM service). OE_ENCLAVE_ABORTING  The operation cannot be completed because the enclave is aborting. OE_ENCLAVE_ABORTED  The operation cannot be completed because the enclave has already aborted. OE_PLATFORM_ERROR  The underlying platform or hardware returned an error. For example, an SGX user-mode instruction failed. OE_INVALID_CPUSVN  The given CPUSVN value is invalid. An SGX user-mode instruction may return this error. OE_INVALID_ISVSVN  The given ISVSNV value is invalid. An SGX user-mode instruction may return this error. OE_INVALID_KEYNAME  The given key name is invalid. An SGX user-mode instruction may return this error. OE_DEBUG_DOWNGRADE  Attempted to create a debug enclave with an enclave image that does not allow it. OE_REPORT_PARSE_ERROR  Failed to parse an enclave report. OE_MISSING_CERTIFICATE_CHAIN  The certificate chain is not available or missing. OE_BUSY  An operation cannot be performed beause the resource is busy. For example, a non-recursive mutex cannot be locked because it is already locked. OE_NOT_OWNER  An operation cannot be performed because the requestor is not the owner of the resource. For example, a thread cannot lock a mutex because it is not the thread that acquired the mutex. OE_INVALID_SGX_CERTIFICATE_EXTENSIONS  The certificate does not contain the expected SGX extensions. OE_MEMORY_LEAK  A memory leak was detected during enclave termination. OE_BAD_ALIGNMENT  The data is improperly aligned for the given operation. This may occur when an output buffer parameter is not suitably aligned for the data it will receive. OE_JSON_INFO_PARSE_ERROR  Failed to parse the trusted computing base (TCB) revocation data or the QE Identity data for the enclave. OE_TCB_LEVEL_INVALID  The level of the trusted computing base (TCB) is not up to date for report verification. OE_QUOTE_PROVIDER_LOAD_ERROR  Failed to load the quote provider library used for quote generation and attestation. OE_QUOTE_PROVIDER_CALL_ERROR  A call to the quote provider failed. OE_INVALID_REVOCATION_INFO  The certificate revocation data for attesting the trusted computing base (TCB) is invalid for this enclave. OE_INVALID_UTC_DATE_TIME  The given UTC date-time string or structure is invalid. This occurs when (1) an element is out of range (year, month, day, hours, minutes, seconds), or (2) the UTC date-time string is malformed. OE_INVALID_QE_IDENTITY_INFO  The QE identity data is invalid. OE_UNSUPPORTED_ENCLAVE_IMAGE  The enclave image contains unsupported constructs. OE_VERIFY_CRL_EXPIRED  The CRL for a certificate has expired. OE_VERIFY_CRL_MISSING  The CRL for a certificate could not be found. OE_VERIFY_REVOKED  The certificate or signature has been revoked. OE_CRYPTO_ERROR  An underlying crypto provider returned an error.
