Supporting these options complicates the design of Graphene and loading
logic significantly, providing little useful functionality:
- loader.exec:
- the main user of it were our tests
- worked only for the first process spawned inside Graphene, as it
was a unidirectional manifest->binary mapping, so the child
process didn't know about the corresponding manifest.
- sgx.sigfile:
- probably all existing usages of it were completely redundant
- was resolved relatively to CWD instead of the executable location,
which made it mostly useless
From now on, the correct location of the files is:
- either place the manifest and sigfile next to the binary, with a
matching name, or
- create a symlink to the binary in the folder where manifests are
stored and launch it through this symlink
# Cap'n Proto and Addressbook example This directory contains the Makefile and the template manifest for the Addressbook example of the Cap'n Proto protocol. Addressbook is the sample application that uses Cap'n Proto from the official documentation (copied from the official GitHub repo, v0.7.0). We use the preinstalled libcapnp library on the host OS instead of downloading the sources, building, and linking Addressbook against the built library (which is possible but would require more effort). This was tested on machines with SGX v1 and Ubuntu 16.04/18.04. Please install the following prerequisites: `sudo apt install -y libcapnp-dev capnproto`. # Quick Start ```sh # build Addressbook and the final manifest make SGX=1 # run original Addressbook ./addressbook write # run Addressbook in non-SGX Graphene ./pal_loader addressbook write # run Addressbook in Graphene-SGX SGX=1 ./pal_loader addressbook write ```
