Change main thread hangs when encounter debugger encounters error to
main thread exits when debugger encounters error
Change main thread blocks when debugger detaches to
main thread continues executing when debugger detaches, and main thread
exits normally when finishing executing
Create trap for error message when wasm_instance_new fails:
- Similar to [this PR](https://github.com/bytecodealliance/wasm-micro-runtime/pull/1526),
but create a wasm_trap_t to output the error msg instead of adding error_buf to the API.
- Trap will need to be deleted by the caller but is not a breaking change as it is only
created if trap is not NULL.
- Add error messages for all failure cases here, try to make them accurate but welcome
feedback for improvements.

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.
Limit max_stack_cell_num/max_csp_num to be no larger than UINT16_MAX,
and don't check all_cell_num in interpreter again.
And refine some codes in interpreter.
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 a widespread bug named CVE-2007-4559, which is a 15 year old bug
in the Python tarfile package. By using extract() or extractall() on a tarfile
object without sanitizing input, a maliciously crafted .tar file could
perform a directory path traversal attack. This patch essentially checks to
see if all tarfile members will be extracted safely and throws an exception
otherwise.
Update build wasm app document, add how to set buildflags for Rust
project to reduce the footprint.
Clear Windows warnings and a shadow warning in aot_emit_numberic.c
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.
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
Clear warnings like below when building LLVM JIT and wamrc:
llvm-project/llvm/include/llvm/ExecutionEngine/Orc/IndirectionUtils.h:73:25:
warning: redundant move in return statement [-Wredundant-move]
73 | return std::move(Err);
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.
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

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.
Support to get/set recv_buf_size/send_buf_size/reuse_port/reuse_addr for wasm app
Add socket APIs for esp-idf platform
Add setsockopt for linux-sgx platform
Allow to wait for a new debugger connection once the previous one
is disconnected:
- when receiving a detach command
- when the client socket is closed (for example, lldb process is killed)
Currently we initialize and destroy LLVM environment in aot_create_comp_context
and aot_destroy_comp_context, which are called in wasm_module_load/unload,
and the latter may be invoked multiple times, which leads to duplicated LLVM
initialization/destroy and may result in unexpected behaviors.
Move the LLVM init/destroy into runtime init/destroy to resolve the issue.
