Current SGX lib-rats wasm module hash is stored in a global buffer,
which may be overwritten if there are multiple wasm module loadings.
We move the module hash into the enclave module to resolve the issue.
And rename the SGX_IPFS macro/variable in Makefile and Enclave.edl to
make the code more consistent.
And refine the sgx-ra sample document.
The current implementation of remote attestation does not take into
account the integrity of the wasm module. The SHA256 of the wasm
module has been put into user_data to generate the quote, and more
parameters are exposed for further verification.
Use the cmake variable `WAMR_BUILD_GLOBAL_HEAP_POOL` and
`WAMR_BUILD_GLOBAL_HEAP_SIZE` to enable/disable the global heap pool
and set its size. And set the default global heap size in core/config.h and
the cmake files.
As a result, the developers who build iwasm can easily enable/disable the
global heap pool and change its size regardless of the iwasm implementation,
without manually finding and patching the right location for that value.
This PR integrates an Intel SGX feature called Intel Protection File System Library (IPFS)
into the runtime to create, operate and delete files inside the enclave, while guaranteeing
the confidentiality and integrity of the data persisted. IPFS can be referred to here:
https://www.intel.com/content/www/us/en/developer/articles/technical/overview-of-intel-protected-file-system-library-using-software-guard-extensions.html
Introduce a cmake variable `WAMR_BUILD_SGX_IPFS`, when enabled, the files interaction
API of WASI will leverage IPFS, instead of the regular POSIX OCALLs. The implementation
has been written with light changes to sgx platform layer, so all the security aspects
WAMR relies on are conserved.
In addition to this integration, the following changes have been made:
- The CI workflow has been adapted to test the compilation of the runtime and sample
with the flag `WAMR_BUILD_SGX_IPFS` set to true
- Introduction of a new sample that demonstrates the interaction of the files (called `file`),
- Documentation of this new feature
Use the semantic versioning (https://semver.org) to replace the current date
versioning system, which is more general and is requested by some developers,
e.g. issue #1357.
There are three parts in the new version string:
- major. Any incompatible modification on ABIs and APIs will lead to an increment
in the value of major, which mainly includes: AOT calling conventions, AOT file
format, wasm_export.h, wasm_c_api.h, and so on.
- minor. It represents new features, including MVP/POST-MVP features, libraries,
WAMR private ones, and so one.
- patch. It represents patches.
The new version will start from 1.0.0. Update the help info and version showing for
iwasm and wamrc.
Implement Berkeley Socket API for Intel SGX
- bring Berkeley socket API in Intel SGX enclaves,
- adapt the documentation of the socket API to mention Intel SGX enclaves,
- adapt _iwasm_ in the mini-product _linux-sgx_ to support the same option as the one for _linux_,
- tested on the socket sample as provided by WAMR (the TCP client/server).
Refine is_xip_file check, when e_type isn't E_TYPE_XIP, just return false
and no need to go through all the other sections of the AOT file.
Refine pointer range check, convert pointer to uintptr_t type before
comparison to yield possible sanitizer pointer overflow error.
Auto detect whether file is XIP file before loading module in posix like and
linux-sgx platforms, and if yes, mmap executable memory automatically to
run the XIP file.
Add document about XIP feature.
Enable test spec cases with XIP feature.
