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.
Enlarge the default wasm operand stack size to 64KB since the original default
size 16KB is a little small, and the operand stack overflow exception is often
thrown when running wasm apps.
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.
Refine the generated LLVM IRs at the beginning of each LLVM AOT/JIT function
to fasten the LLVM IR optimization:
- Only create argv_buf if there are func calls in this function
- Only create native stack bound if stack bound check is enabled
- Only create aux stack info if there is opcode set_global_aux_stack
- Only create native symbol if indirect_mode is enabled
- Only create memory info if there are memory operations
- Only create func_type_indexes if there is opcode call_indirect
Add a new options to control the native stack hw bound check feature:
- Besides the original option `cmake -DWAMR_DISABLE_HW_BOUND_CHECK=1/0`,
add a new option `cmake -DWAMR_DISABLE_STACK_HW_BOUND_CHECK=1/0`
- When the linear memory hw bound check is disabled, the stack hw bound check
will be disabled automatically, no matter what the input option is
- When the linear memory hw bound check is enabled, the stack hw bound check
is enabled/disabled according to the value of input option
- Besides the original option `--bounds-checks=1/0`, add a new option
`--stack-bounds-checks=1/0` for wamrc

Add macro WASM_ENABLE_WORD_ALING_READ to enable reading
1/2/4 and n bytes data from vram buffer, which requires 4-byte addr
alignment reading.
Eliminate XIP AOT relocations related to the below ones:
i32_div_u, f32_min, f32_max, f32_ceil, f32_floor, f32_trunc, f32_rint
Allow to unregister (or unload) the previously registered native libs,
so that no need to restart the whole engine by using
`wasm_runtime_destroy/wasm_runtime_init`.
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.
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.

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
Implement more socket APIs, refer to #1336 and below PRs:
- Implement wasi_addr_resolve function (#1319)
- Fix socket-api byte order issue when host/network order are the same (#1327)
- Enhance sock_addr_local syscall (#1320)
- Implement sock_addr_remote syscall (#1360)
- Add support for IPv6 in WAMR (#1411)
- Implement ns lookup allowlist (#1420)
- Implement sock_send_to and sock_recv_from system calls (#1457)
- Added http downloader and multicast socket options (#1467)
- Fix `bind()` calls to receive the correct size of `sockaddr` structure (#1490)
- Assert on correct parameters (#1505)
- Copy only received bytes from socket recv buffer into the app buffer (#1497)

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.
Upgrade `cmake_minimum_required` from `(VERSION 2.8)` to `(VERSION 2.9)` to
yield the warning:
"Compatibility with CMake < 2.8.12 will be removed from a future version of CMake"
Add "-Wno-unused" for CMAKE_CXX_FLAGS to yield the compilation warnings
when build LLVM JIT.
Fix the link error when code coverage is enabled.
Unbreak builds with a bit older nuttx/apps for now.
Note: The default value here (0) was chosen to match the new default
in nuttx/apps, which is different from the old value used before
the introduction of WASM_STACK_GUARD_SIZE. (1024)
Let iwasm return non-zero value when running failed
so that the caller (e.g. test framework) can check the
running status according to the return value.
Add a new option WAMR_BUILD_STACK_GUARD_SIZE to set the custom
stack guard size. For most RTOS systems, we use the native stack base
address as the check boundary which may be not safe as POSIX based
systems (like Linux).
Import WAMR Fast JIT which is a lightweight JIT with quick startup, small footprint,
relatively good performance (~40% to ~50% of LLVM JIT) and good portability.
Platforms supported: Linux, MacOS and Linux SGX.
Arch supported: x86-64.
When WAMR_BUILD_TARGET isn't set, choosing right target is decided
by checking `CMAKE_SIZEOF_VOID_P` variable. However, choosing `X86_32`
target is not doing specifically checking size of void pointer. It is kind
a fallback target for others.
This patch explicitly checks the size of void pointer before setting the target
to `X86_32` to fix the issue.
