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
Lighttpd Example
This directory contains an example for running lighttpd in Graphene, including the Makefile and a template for generating the manifest. We tested lighttpd on Ubuntu 16.04.
Building lighttpd source
For this example, we build lighttpd from source instead of using an existing binary. To build lighttpd on Ubuntu 16.04, please make sure that the following packages are installed:
sudo apt-get install -y build-essential apache2-utils
Linux
Run make (non-debug) or make DEBUG=1 (debug) in the directory.
SGX
Run make SGX=1 (non-debug) or make SGX=1 DEBUG=1 (debug) in the directory to prepare lighttpd to
run on SGX.
Running lighttpd natively, under Graphene, and under Graphene-SGX
Execute one of the following commands to start lighttpd either natively (non-Graphene), on Graphene or Graphene-SGX, respectively.
make start-native-server
make start-graphene-server
SGX=1 make start-graphene-server
Because these commands will start the lighttpd server in the foreground, you will need to open another console to run the client.
Once the server has started, you can test it with wget
wget http://127.0.0.1:8003/random/10K.1.html
You may also run the benchmark script using ab (Apachebench)
./benchmark-http.sh 127.0.0.1:8003
Use Ctrl-C to terminate the server once you are finished testing lighttpd.
Clean up
There are two commands to clean up the directory:
make clean: Remove manifest, signature, and token files.make distclean: Remove the lighttpd source code and installation directory.
