Added new APIs in sgx_uae_service.h and sgx_ukey_exchange.h to support ECDSA quote based remote attestation. The set of legacy APIs supports EPID only and the set of new APIs supports ECDSA quotes. Enhanced Edger8r with structure deep-copy feature. Fixed bugs. Signed-off-by: Li, Xun <xun.li@intel.com>

* The framework returns <code>ServiceReference</code> objects from the

* <code>BundleContext::GetServiceReferences</code> methods.
|
|
* <p>
|
|
* A <code>ServiceReference</code> object may be shared between bundles and
|
|
* can be used to examine the properties of the service and to get the service
|
|
* object.
|
|
* <p>
|
|
* Every service registered in the framework has a unique
|
|
* <code>ServiceRegistration</code> object and may have multiple, distinct
|
|
* <code>ServiceReference</code> objects referring to it.
|
|
* <code>ServiceReference</code> objects associated with a
|
|
* <code>ServiceRegistration</code> are considered equal
|
|
* (more specifically, their <code>operator==()</code>
|
|
* method will return <code>true</code> when compared).
|
|
* <p>
|
|
* If the same service object is registered multiple times,
|
|
* <code>ServiceReference</code> objects associated with different
|
|
* <code>ServiceRegistration</code> objects are not equal.
