Open Enclave  0.18.0

◆ _oe_result

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_INVALID_ENDORSEMENT 

The quote verification collateral 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_VERIFY_FAILED_TO_FIND_VALIDITY_PERIOD 

Could not find a valid validity period.

OE_CRYPTO_ERROR 

An underlying crypto provider returned an error.

OE_INCORRECT_REPORT_SIZE 

OE report size does not match the expected size.

OE_QUOTE_VERIFICATION_ERROR 

Quote verification error.

OE_QUOTE_ENCLAVE_IDENTITY_VERIFICATION_FAILED 

Quote enclave identity verification failed.

OE_QUOTE_ENCLAVE_IDENTITY_UNIQUEID_MISMATCH 

Unique id of the quoting enclave does not match expected value.

QE_QUOTE_ENCLAVE_IDENTITY_PRODUCTID_MISMATCH 

Product id of the quoting enclave does not match expected value.

OE_VERIFY_FAILED_AES_CMAC_MISMATCH 

AES CMAC of the report does not match the expected value.

OE_CONTEXT_SWITCHLESS_OCALL_MISSED 

Failed to post a switchless call to host workers.

OE_THREAD_CREATE_ERROR 

Thread creation failed.

OE_THREAD_JOIN_ERROR 

Thread join failed.

OE_ALREADY_EXISTS 

The desired resource already exists.

OE_ALREADY_INITIALIZED 

The desired resource has already been initialized.

OE_QUOTE_HASH_MISMATCH 

The hash of claims section in the quote does not match the hash value held in the report_data field.

This occurs when claims are tampered.

OE_INVALID_SGX_SIGNING_KEY 

The signing key provided cannot be used for SGX signing.

This is usually because the key is not an 3084-bit RSA key with exponent 3.

OE_INVALID_IMAGE 

The binary image being loaded into the enclave could not be parsed.

OE_QUOTE_LIBRARY_LOAD_ERROR 

Failed to load the quote library used for quote generation and attestation.

OE_SGX_QUOTE_LIBRARY_ERROR 

The library API used for SGX quote generation and attestation failed.
