This is a major refactor of the way manifests are loaded and handled, which will be followed by a complete rework of the loader code (which will include e.g. centralized config). Changes/fixes: - Huge part of manifest handling was refactored and untangled. - Starting without a manifest is now disallowed. This was actually accidentally broken for some time and no one complained. It also makes little sense in practice and in Graphene's overall design, e.g. it conflicts with protected argv. - Now we only allow starting by giving the executable, not manifest (the magic resolution logic was removed). - Now manifests are sent over pipes between parent and children, instead of children finding and loading them on their own. This is a preparation for the upcoming centralized manifests change. - Previously manifests were parsed 2 times on Linux and 3 times on Linux-SGX (by untrusted PAL, trusted PAL and LibOS). This is now fixed. - The common `pal_main()` now requires that the backend-specific PAL loader loads the manifest before calling it. SGX code already has to do it (for proper initialization), so let's unify this interface for all PALs. - Fix for a PAL crash when manifest size was divisible by page size (sic!). NULL termination was missing, but most of the time the padding to page size saved Graphene from crashing.
Node.js
This directory contains a Makefile and template manifest to run Node.js on Graphene. We tested it with Node.js 8.10.0 on Ubuntu 18.04. This example uses Node.js installed on the system instead of compiling from source as some of the other examples do.
The Makefile and the template manifest contain comments to hopefully make them easier to understand.
Quick Start
To run the regression test execute make check. To do the same for SGX, execute make SGX=1 check.
