This syscall doesn't need allocating stack or TLS and it's expected from the application
to do that instead. E.g. WASI-libc already does this for `pthread_create`.
Also fix some of the examples to allocate memory for stack and not use stack before
the stack pointer is set to a correct value.
For now this implementation uses thread manager.
Not sure whether thread manager is needed in that case. In the future there'll be likely another syscall added (for pthread_exit) and for that we might need some kind of thread management - with that in mind, we keep thread manager for now and will refactor this later if needed.
Use sha256 to hash binary file content. If the incoming wasm binary is
cached before, wasm_module_new() simply returns the existed one.
Use -DWAMR_BUILD_WASM_CACHE=0/1 to control the feature.
OpenSSL 1.1.1 is required if the feature is enabled.
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.
Fix build error in sample ref-types and wasm-c-api caused by the
version of wat2wasm: refine makefile to auto detect the wat2wasm
version and add the compile flag accordingly.
A limitation of the current implementation of SGX IPFS in WAMR is that
it prevents to open files which are not in the current directory.
This restriction is lifted and can now open files in paths, similarly to the
WASI openat call, which takes into account the sandbox of the file system.
Improve the documentation for setting up SGX-RA using WAMR, based on
the feedback in #1670.
This notably highlights the dependency on Intel PCS and PCCS and how to
install/configure them.
Allow to have multiple stores in an engine and multiple instances
in a store. Letting a wasm_function_t pass its wasm_store_t to make
it more efficient.
Real world native libs likely need to access the wasm_runtime_xxx API.
This example demonstrates it.
Build vmlib as a shared lib to make it straightforward to share a
single runtime instance between iwasm and native libs.
Add CIs to enable the release process of a new version of WAMR,
and build and publish the binary files when a version is released,
including iwasm, wamrc, lldb, vscode-extension and wamr-ide for
Ubuntu-20.04, Ubuntu-22.04 and MacOS.
And refine the CIs to test spec cases.
Refactor the layout of interpreter and AOT module instance:
- Unify the interp/AOT module instance, use the same WASMModuleInstance/
WASMMemoryInstance/WASMTableInstance data structures for both interpreter
and AOT
- Make the offset of most fields the same in module instance for both interpreter
and AOT, append memory instance structure, global data and table instances to
the end of module instance for interpreter mode (like AOT mode)
- For extra fields in WASM module instance, use WASMModuleInstanceExtra to
create a field `e` for interpreter
- Change the LLVM JIT module instance creating process, LLVM JIT uses the WASM
module and module instance same as interpreter/Fast-JIT mode. So that Fast JIT
and LLVM JIT can access the same data structures, and make it possible to
implement the Multi-tier JIT (tier-up from Fast JIT to LLVM JIT) in the future
- Unify some APIs: merge some APIs for module instance and memory instance's
related operations (only implement one copy)
Note that the AOT ABI is same, the AOT file format, AOT relocation types, how AOT
code accesses the AOT module instance and so on are kept unchanged.

Add a couple of socket examples that can be used with WAMR:
- The `timeout_client` and `timeout_server` examples demonstrate socket
send and receive timeouts using the socket options
- The `multicast_client` and `multicast_server` examples demonstrate receiving
multicast packets in WASM
And add several macro controls for `socket_opts` example.
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

When WAMR_BUILD_TARGET isn't set, choosing right target is decided

Refer to [Networking API design](https://github.com/WebAssembly/WASI/issues/370)
and [feat(socket): berkeley socket API v2](https://github.com/WebAssembly/WASI/pull/459):
- Support the socket API of synchronous mode, including `socket/bind/listen/accept/send/recv/close/shutdown`,
the asynchronous mode isn't supported yet.
- Support adding `--addr-pool=<pool1,pool2,..>` argument for command line to identify the valid ip address range
- Add socket-api sample and update the document
The littlevgl library had changed its name and domain to [LVGL](https://lvgl.io).

We change some names and links accordingly.
Also remove the cloning for tlsf library as it isn't used now.
Currently when calling wasm_runtime_call_wasm() to invoke wasm function
with externref type argument from runtime embedder, developer needs to
use wasm_externref_obj2ref() to convert externref obj into an internal ref
index firstly, which is not convenient to developer.
To align with GC feature in which all the references passed to
wasm_runtime_call_wasm() can be object pointers directly, we change the
interface of wasm_runtime_call_wasm() to allow to pass object pointer
directly for the externref argument, and refactor the related codes, update
the related samples and the document.
Refer to https://github.com/WebAssembly/WASI/blob/main/design/application-abi.md
to check the WASI ABI compatibility:
- Command (main module) may export _start function with signature "()"
- Reactor (sub module) may export _initialize function with signature "()"
- _start and _initialize can not be exported at the same time
- Reactor cannot export _start function
- Command and Reactor must export memory
And
- Rename module->is_wasi_module to module->import_wasi_api
- Refactor wasm_loader_find_export()
- Remove MULTI_MODULE related codes from mini_loader
- Update multi-module samples
- Fix a "use-after-free" issue. Since we reuse the memory instance of sub module,

And update the sensor sample by creating two sensors to confirm that
the fix works correctly.
Enable ref types feature and bulk memory feature by default for wamrc
and provide "--disable-ref-types", "--disable-bulk-memory" to disable
them.
And remove the ref_type_flag option in wasm_loader.c which is used to
control whether to enable ref types or not when ENABLE_REF_TYPES
macro is enabled in wamrc. As the wasm binary format with ref types
is compatible with the binary format before, we can remove the option.
Also update the spec test scripts.
Allow empty import array (but not NULL) for wasm-c-api wasm_instance_new,
which makes the code more robust, especially in use cases where imports
might be constructed dynamically.
And add a test case in samples/wasm-c-api/src/empty_imports.c to test it.
Implement the latest SIMD opcodes and update LLVM 13.0,
update the llvm build scripts, update the sample workloads‘ build scripts,

* wasm_instance_new() has been updated to use wasm_extern_vec_t*
* wasm_instance_new_with_args() has been updated to use wasm_extern_vec_t*
* wasm_runtime_invoke_c_api_native() has been updated to support vector types
in native callbacks without modifying the contract with the interpreter code.
* All users of the modified functions (including samples/wasm-c-api/src/*.c)
