When installers are used, sgx-sdk of Occlum version could have conflicts with official sgx-sdk.
This patch will make sure Occlum command use Occlum specific sgx-sdk.
Also add symbolic links to PAL library of hardware mode when installing.
This commit mainly accomplish two things:
1. Use makefile to manage dependencies for `occlum build`, which can save lots of time
2. Take dirs `build`, `run` outside from `.occlum`. Remove env var "OCCLUM_INSTANCE_DIR"
Occlum-compatible executable binaries must be Position-Independent
Executable (PIE). Previously, to build such binaries, the users need to
explicitly give `-buildmode=pie` flag to `occlum-go`. Apparently, this
is error-prone. This commit sets `-buildmode=pie` by default for `occlum-go`.
In addition, this commit upgrades the Go version to 1.13.7.
Update the occlum.json to align with the gen_enclave_conf design.
Below is the two updated structures:
"metadata": {
"product_id": 0,
"version_number": 0,
"debuggable": true
},
"resource_limits": {
"max_num_of_threads": 32,
"kernel_space_heap_size": "32MB",
"kernel_space_stack_size": "1MB",
"user_space_size": "256MB"
}
This commit provides a modified Go runtime in Docker image.
Now we can build a Go program using `occlum-go`, then run it
in SGX enclaves by Occlum.
The Golang demo demonstrates how to build and run a web server
program written in Go.
Fix std::alloc::Alloc not found
The lastest Rust changes the trait to std::alloc::AllocRef.
Update the docker files to support sgx 2.9.1
Remove the compilerRT dependency for rust sdk update
The CLI tool is robust in the sense that it can handle the execution of
init/build/run/gdb commands in any order (as long as the commands are invoked
sequentially, not concurrently).
1. Use arch_prctl to replace RDFSBASE/WRFSBASE
Ptrace can't get right value if WRFSBASE is called which
will make debugger fail in simulation mode. Use arch_prctl
to replace these instructions in simulation mode.
2. Disable the busy thread in exit_group test
exit_group doesn't have a real implementation yet but test
under SGX simulation mode give core dump for exit_group test.
Disable the busy loop thread and the core dump disappear.
3. Add SDK lib path to LD_LIBRARY_PATH
Linker sometims can't find urts_sim and uae_service_sim when
running. Explicitly add path to LD_LIBRARY_PATH when running
occlum command.
