Bug description:
[Impact]
We have included the DCAP version of SGX into the linux-azure kernels
in order to provide a signed version of this driver that can be used
with secure boot in Azure instances.
Since a new version of this driver was released, we should update the
embedded driver:
https://github.com/intel/SGXDataCenterAttestationPrimitives/tree/LD_1.33/driver/linux
[Test Case]
- Install the new kernel on an ACC azure instance.
- Ensure the module loads properly.
- Check if ECL (provided on the azure images) is working properly.
[Regression Potential]
The changes are extensive, but both Canonical and Microsoft perform
validation tests on SGX. Besides that, the change is restricted to
linux-azure running on specific instances.
