Added socket send and recv timeout options with implementation for posix platform.
This is part of a extending support for sockets in WASI. #1336.
Also add sample that sets and reads back the send and receive timeouts using
the native function binding.
esp-idf: Make esp-idf support Libc WASI
1. Support to get WASM APP libs' DIR from upper layer
2. Add SSP support for esp-idf platform
3. Change the errno of readlinkat
Thread data should not be destroyed when thread exits, or other thread
may not be able to join it. This PR saves the thread data into thread data
list when thread exits, sets thread status and stores the return value, so
that other thread can join it.
Also set MEM_TOP_DOWN flag for Windows VirtualAlloc to yield LLVM
JIT relocation error.
And set opt/size level to 3 for LLVM JIT for future use, currently the flags
are not used by LLVM JIT.
Slightly changed the interface sock_addr_remote - since we already
have a `__wasi_addr_t` structure which is an union, there's no need
for passing length around - the address buffer will always have the
right length (i.e. max of all address families).
Slightly change the __wasi_sock_addr_local interface - since we already have
a `__wasi_addr_t` structure which is an union, there's no need for passing the
length around - the address buffer will always have the right length (i.e. max
of all address families).
Fix socket-api byte order issue for systems where host byte order
and network byte order are the same:
- Document data structures used for storing IP addresses
- Fix bug in bind and connect methods by updating code in wasi_socket_ext
Implement wasi_addr_resolve function.
Also slightly modify the interface to make it more accessible for the end user:
- replace port argument with the service - so the user can actually get the port for a given service if unknown
- introduce __wasi_addr_info_t and use it as a buffer for addresses, instead of generic buffer
- introduce __wasi_addr_info_hints_t so user can enable filtering on the syscall level (and therefore use smaller buffers for addresses)
- add max_size parameter for the API as an output - in case the number of addresses is bigger than the buffer size, user can repeat the call with bigger buffer
This change is very minimalistic, and it doesn't include the followings:
1. implementation of getaddrinfo in the lib-socket
2. sample application
Which are to be added in the following change #1336
Enhance the hw bound check reported in #1262:
When registering signal handlers for SIGSEGV & SIGBUS in boundary
check with hardware trap, preserve the previous handlers for signal
SIGSEGV and SIGBUS, and forward the signal to the preserved signal
handlers if it isn't handled by hw bound check.

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).
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
In some Linux systems whose kernel version is smaller than 2.6.38, the macro
MADV_HUGEPAGE isn't introduced yet which causes compilation error.
Add macro control to fix the compilation error.
Allow compilation on Windows MinGW, see build_wamr.md for more details.
Note that WASI and some other smallish details are still not supported, but
we have a starting point. See more discussion at #993
Implement pthread_cond_broadcast wrapper for lib-pthread
- support pthread_cond_broadcast wrapper for posix/linux-sgx/windows
- update document for building multi-thread wasm app with emcc
Refactor LLVM Orc JIT to actually enable the lazy compilation and speedup
the launching process:
https://llvm.org/docs/ORCv2.html#laziness
Main modifications:
- Create LLVM module for each wasm function, wrap it with thread safe module
so that the modules can be compiled parallelly
- Lookup function from aot module instance's func_ptrs but not directly call the
function to decouple the module relationship
- Compile the function when it is first called and hasn't been compiled
- Create threads to pre-compile the WASM functions parallelly when loading
- Set Lazy JIT as default, update document and build/test scripts
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.
The return address of pthread_get_stackaddr_np() in MacOS and NuttX
may be the base address or the end (boundary) address of the native stack,
if it is the end address, we get the base address according to it and the
stack size, so as to get the actual stack boundary address correctly.
