1. Add a separate net/ directory for the network subsystem;
2. Move some existing socket code to net/;
3. Implement sendmsg/recvmsg with OCalls;
4. Extend client/server test cases.
1. Change the port for server_poll to listen to avoid "address in use" conflict
between test/server and test/server_epoll, and add port as an argument for
test/client to send message
2. As posix-spwan may fail, change the fixed number of processes to spawn to
the number of processes successfully spawned in server_epoll
1. Now we support set App's env in Occlum.json, for example:
"env": [
"OCCLUM=yes",
"TEST=true"
]
2. Rewrite env test cases
3. Update Dockerfile to install "jq" tool
* Add patch to Rust SGX SDK to enable integrity-only SgxFile
* Upgrade to the new SEFS extended with the integrity-only mode
* Use integrity-only SEFS for /bin and /lib in test
* Add the MAC of integrity-only SEFS to Occlum.json in test
* Mount multiple FS according to Occlum.json
* Check the MACs of integrity-only SEFS images
