Every subfolder under [WAMR application framework](./core/app-framework) folder is a compilation configurable component. The developers can copy the template folder to create new components to the application framework. If a component needs to export native functions to the WASM application, refer to the [export_native_api.md](./doc/export_native_api.md) .

# Remote application management
|
||||
|
||||
The WAMR application manager supports remote application management from host environment or the cloud through any physical communications such as TCP, UPD, UART, BLE, etc. Its modular design makes it able to support application management for different managed runtimes.

WAMR SDK
|
||||
==========
|
||||
|
||||
The **wamr-sdk** tools build the WAMR to both **runtime SDK** for embedding by your native codes and **APP SDK** for developing the WASM applications. A SDK profile presents a configuration of build parameters for the selection of CPU arch, software platforms, execution mode, libc and application framework components.
|
||||
Usually there are two tasks for integrating the WAMR into a particular project:
|
||||
|
||||
**Note**: [WASI-SDK](https://github.com/CraneStation/wasi-sdk/releases) version 7 and above should be installed before building the WAMR SDK.
|
||||
- Select what WAMR components (vmcore, libc, app-mgr, app-framework components) to be integrated, and get the associated source files added into the project building configuration
|
||||
- Generate the APP SDK for developing the WASM apps on the selected libc and framework components
|
||||
|
||||
### Menu configuration for building SDK
|
||||
|
||||
Menu configuration is supported for easy integration of runtime components and application libraries for the target architecture and platform.
|
||||
|
||||
```
|
||||
cd wamr-sdk
|
||||
./build_sdk.sh -i -n [profile name]
|
||||
```
|
||||
|
||||
<img src="./doc/pics/wamr_menu_config.png" alt="wamr build menu configuration" style="zoom:80%;" />
|
||||
|
||||
After the menu configuration is finished, the building process is automatically started. When the building gets successful, the SDK package is generated under folder $wamr-sdk/out/{profile}, and the header files of configured components were copied into the SDK package.
|
||||
|
||||
The directory structure of a SDK package with profile name "simple":
|
||||
|
||||
```
|
||||
simple/
|
||||
├── app-sdk
|
||||
│ ├── libc-builtin-sysroot
|
||||
│ │ ├── include
|
||||
│ │ └── share
|
||||
│ └── wamr-app-framework
|
||||
│ ├── include
|
||||
│ │ ├── bi-inc
|
||||
│ │ └── wa-inc
|
||||
│ ├── lib
|
||||
│ └── share
|
||||
└── runtime-sdk
|
||||
├── include
|
||||
│ └── bi-inc
|
||||
└── lib
|
||||
```
|
||||
The **[WAMR SDK](./wamr-sdk)** tools is helpful to finish the two tasks quickly. It supports menu configuration for selecting WAMR components and builds the WAMR to a SDK package that includes **runtime SDK** and **APP SDK**. The runtime SDK is used for building the native application and the APP SDK should be shipped to WASM application developers.
|
||||
|
||||
|
||||
|
||||
### Use Runtime SDK
|
||||
|
||||
The folder "**runtime-sdk**" contains all the header files and library files for integration with project native code.
|
||||
|
||||
### Build WASM applications with APP-SDK
|
||||
|
||||
The folder “**app-sdk**” contains all the header files and WASM library for developing the WASM application. For C/C++ based WASM applications, the developers can use conventional cross-compilation procedure to build the WASM application. Refer to [build WASM applications](./doc/build_wasm_app.md) for the details.

Application framework

|

## Directory structure
|
||||
|
||||
|
||||
|
||||
This folder "app-native-shared" is for the source files shared by both WASM APP and native runtime
|
||||
|
||||
- The c files in this directory are compiled into both the WASM APP and runtime.
|
||||
- The header files for distributing to SDK are placed in the "bi-inc" folder.
|
||||
|
||||
|
||||
|
||||
This folder "template" contains a pre-defined directory structure for a framework component. The developers can copy the template folder to create new components to the application framework.
|
||||
|
||||
|
||||
|
||||
Every other subfolder is framework component. Each component contains two library parts: **app and native**.
|
||||
|
||||
- The "base" component provide timer API and inter-app communication support. It must be enabled if other components are selected.
|
||||
- Under the "app" folder of a component, the subfolder "wa_inc" holds all header files that should be included by the WASM applications
|
||||
|
||||
|
||||
|
||||
## Application framework basic model
|
||||
|
||||
The app framework is built on top of two fundamental operations:
|
||||
|
||||
- [Native calls into WASM function](../../doc/embed_wamr.md)
|
||||
|
||||
- [WASM app calls into native API](../../doc/export_native_api.md)
|
||||
|
||||
Asynchronized programming model is supported for WASM applications
|
||||
|
||||
- Every WASM app has its own sandbox and thread
|
||||
|
||||
- Queue and messaging
|
||||
|
||||
<img src="../../doc/pics/app_framework.PNG" style="zoom:67%;" />
|
||||
|
||||
|
||||
|
||||
## Customized building of app framework
|
||||
|
||||
A component can be compilation configurable to the runtime. The wamr SDK tool "build_sdk.sh" supports menu config to select app components for building a customized runtime.
|
||||
|
||||
A number of CMAKE variables are defined to control build of framework and components. You can create a cmake file for defining these variables and include it in the CMakeList.txt for your software, or pass it in "-x" argument when run the [build_sdk.sh](../../wamr-sdk/build_sdk.sh) for building the runtime SDK.
|
||||
|
||||
```cmake
|
||||
set (WAMR_BUILD_APP_FRAMEWORK 1)
|
||||
set (WAMR_BUILD_APP_LIST WAMR_APP_BUILD_BASE)
|
||||
```
|
||||
|
||||
Variables:
|
||||
|
||||
- **WAMR_BUILD_APP_FRAMEWORK**: enable the application framework
|
||||
- **WAMR_BUILD_APP_LIST**: the selected components to be built into the final runtime
|
||||
|
||||
|
||||
|
||||
The configuration file can be generated through the wamr-sdk menu config:
|
||||
|
||||
```bash
|
||||
cd wamr-sdk
|
||||
./build_sdk -n [profile] -i
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Create new components
|
||||
|
||||
Generally you should follow following steps to create a new component:
|
||||
|
||||
- Copy the “template” for creating a new folder
|
||||
|
||||
- Implement the app part
|
||||
|
||||
- If your component exports native function to WASM, ensure your created a header file under app for declaring the function prototype.
|
||||
- If you component provides header files for the WASM applications to include, ensure it is placed under subfolder "wa_inc".
|
||||
|
||||
- Implement the native part
|
||||
|
||||
- If your native function is exported to WASM, you need to create an inl file for the registration. It can be any file name, assuming the file name is "my_component.inl" here:
|
||||
|
||||
```c
|
||||
//use right signature for your functions
|
||||
EXPORT_WASM_API_WITH_SIG(wasm_my_component_api_1, "(i*~)i"),
|
||||
EXPORT_WASM_API_WITH_SIG(wasm_my_component_api_2, "(i)i"),
|
||||
```
|
||||
|
||||
- Ensure "wasm_lib.cmake" is provided as it will be included by the WAMR SDK building script
|
||||
|
||||
- Add a definition in "wasm_lib.cmake" for your component, e.g.
|
||||
|
||||
```cmake
|
||||
add_definitions (-DAPP_FRAMEWORK_MY_COMPONENT)
|
||||
```
|
||||
|
||||
- Modify the file [app_ext_lib_export.c](./app_ext_lib_export.c) to register native APIs exported for the new introduced component. Skip it if not exporting native functions.
|
||||
|
||||
```
|
||||
#include "lib_export.h"
|
||||
|
||||
...
|
||||
#ifdef APP_FRAMEWORK_MY_COMPONENT // this definition is created in wasm_lib.cmake

Embed WAMR into software production

Embedding WAMR guideline
|
||||
=====================================
|
||||
|
||||
|
||||
|
||||
**Note**: All the embedding APIs supported by the runtime are defined under folder [core/iwasm/include](../core/iwasm/include). The API details are available in the header files.
|
||||
|
||||
## The initialization procedure
|
||||
|
||||
|
||||
|
||||
A typical WAMR API usage is shown below (some return value checks are ignored):
|

|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Native calls WASM functions and passes parameters
|
||||
|
||||
After a module is instantiated, the runtime native can lookup WASM functions by the names and call them.
|
||||
|
||||
```c
|
||||
unit32 argv[2];
|
||||
|
||||
// lookup a WASM function by its name
|
||||
func = wasm_runtime_lookup_function(module_inst, "fib", NULL);
|
||||
|
||||
// creat a excution environment which can be used by executing WASM functions
|
||||
exec_env = wasm_runtime_create_exec_env(module_inst, stack_size);
|
||||
|
||||
// arguments are always transferred in 32 bits element
|
||||
argv[0] = 8;
|
||||
if (wasm_runtime_call_wasm(exec_env, func, 1, argv_buf) ) {
|
||||
|
||||
// call the WASM function
|
||||
if (wasm_runtime_call_wasm(exec_env, func, 1, argv) ) {
|
||||
|
||||
/* the return value is stored in argv[0] */
|
||||
printf("fib function return: %d\n", argv[0]);
|
||||
}
|
||||
else {
|
||||
printf("%s\n", wasm_runtime_get_exception(module_inst));
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
The parameters are transferred in an array of 32 bits elements. For parameters that occupy 4 or fewer bytes, each parameter can be a single array element. For parameters in types like double or int64, each parameter will take two array elements. The function return value will be sent back in the first one or two elements of the array according to the value type. See the sample code below:
|
||||
|
||||
```c
|
||||
unit32 argv[6];
|
||||
char arg1 = 'a';
|
||||
int arg2 = 10;
|
||||
double arg3 = 1.0;
|
||||
int 64 arg4 = 100;
|
||||
double ret;
|
||||
|
||||
argv[0] = arg1;
|
||||
argv[1] = arg2;
|
||||
|
||||
// use memory copy for 8 bytes parameters rather than
|
||||
// *(double*)(&argv[2]) = arg3 here because some archs
|
||||
// like ARM, MIPS requires address is 8 aligned.
|
||||
// Or use the aligned malloc or compiler align attribute
|
||||
// to ensure the array address is 8 bytes aligned
|
||||
memcpy(&argv[2], &arg3, sizeof(arg3));
|
||||
memcpy(&argv[4], &arg4, sizeof(arg4));
|
||||
|
||||
//
|
||||
// attention: the arg number is 6 here since both
|
||||
// arg3 and arg4 each takes 2 elements
|
||||
//
|
||||
wasm_runtime_call_wasm(exec_env, func, 6, argv);
|
||||
|
||||
// if the return value is type of 8 bytes, it takes
|
||||
// the first two array elements
|
||||
memcpy(&ret, &argv[0], sizeof(ret));
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Pass buffer to WASM function
|
||||
|
||||
|
||||
|
||||
If we need to transfer a buffer to WASM function, we can pass the buffer address through a parameter. **Attention**: The sandbox will forbid the WASM code to access outside memory, we must **allocate the buffer from WASM instance's own memory space and pass the buffer address in instance's space (not the runtime native address)**.
|
||||
|
||||
|
||||
|
||||
There are two runtime APIs available for this purpose.
|
||||
|
||||
```c
|
||||
/*
|
||||
* description: malloc a buffer from instance's private memory space.
|
||||
*
|
||||
* return: the buffer address in instance's memory space (pass to the WASM funciton)
|
||||
* p_native_addr: return the native address of allocated memory
|
||||
* size: the buffer size to allocate
|
||||
*/
|
||||
int32_t
|
||||
wasm_runtime_module_malloc(wasm_module_inst_t module_inst,
|
||||
uint32_t size,
|
||||
void **p_native_addr);
|
||||
|
||||
/*
|
||||
* description: malloc a buffer from instance's private memory space,
|
||||
* and copy the data from another native buffer to it.
|
||||
* return: the buffer address in instance's memory space (pass to the WASM funciton)
|
||||
* src: the native buffer address
|
||||
* size: the size of buffer to be allocated and copy data

||||

||||
wasm_runtime_module_dup_data(WASMModuleInstanceCommon *module_inst,

||||
const char *src,
|
||||
uint32 size);
|
||||
```
|
||||
|
||||
|
||||
|
||||
Usage sample:
|
||||
|
||||
```c
|
||||
char * buffer = NULL;
|
||||
int32_t buffer_for_wasm;
|
||||
|
||||
buffer_for_wasm = wasm_runtime_module_malloc(module_inst, 100, &buffer);
|
||||
if(buffer_for_wasm != 0)
|
||||
{
|
||||
unit32 argv[2];
|
||||
strncpy(buffer, "hello", 100); // use native address for accessing in runtime
|
||||
argv[0] = buffer_for_wasm; // pass the buffer address for WASM space.
|
||||
argv[1] = 100; // the size of buffer
|
||||
wasm_runtime_call_wasm(exec_env, func, 2, argv);
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Pass structured data to WASM function
|
||||
|
||||
We can't pass structure data or class objects through the pointer since the memory layout can different in two worlds. The way to do it is serialization. Refer to [export_native_api.md](./export_native_api.md) for the details.
|
||||
|
||||
|
||||
|
||||
## The deinitialization procedure
|
||||
|
||||

Export native API to WASM application
|
||||
=======================================================
|
||||
|
||||
The basic working flow for WASM application calling into the native API is shown in the following diagram:
|
||||
|
||||
|
||||
|
||||
|
||||
WAMR provides the macro `EXPORT_WASM_API` to enable users to export a native API to a WASM application. WAMR has implemented a base API for the timer and messaging by using `EXPORT_WASM_API`. This can be a point of reference for extending your own library.
|
||||
Exporting native API steps
|
||||
--------------------------
|
||||
|
||||
#### Step 1: Declare the function interface in WASM app
|
||||
|
||||
Create a header file in a WASM app and declare the functions that are exported from native. In this example, we declare foo and foo2 as below in the header file "example.h"
|
||||
|
||||
```c
|
||||
/*** file name: example.h ***/
|
||||
|
||||
int foo(int a, int b);
|
||||
void foo2(char * msg, char * buffer, int buf_len);
|
||||
```
|
||||
|
||||
|
||||
|
||||
#### Step 2: Define the native API
|
||||
|
||||
Define the native functions which are executed from the WASM app in the runtime source file. The native function can be any name, for example **foo_native** and **foo2** here:
|
||||
|
||||
``` C
|
||||
static NativeSymbol extended_native_symbol_defs[] = {
|
||||
EXPORT_WASM_API(wasm_register_resource),
|
||||
EXPORT_WASM_API(wasm_response_send),
|
||||
EXPORT_WASM_API(wasm_post_request),
|
||||
EXPORT_WASM_API(wasm_sub_event),
|
||||
EXPORT_WASM_API(wasm_create_timer),
|
||||
EXPORT_WASM_API(wasm_timer_set_interval),
|
||||
EXPORT_WASM_API(wasm_timer_cancel),
|
||||
EXPORT_WASM_API(wasm_timer_restart)
|
||||
int foo_native(wasm_exec_env_t exec_env , int a, int b)
|
||||
{
|
||||
return a+b;
|
||||
}
|
||||
|
||||
void foo2(wasm_exec_env_t exec_env, char * msg, uint8 * buffer, int buf_len)
|
||||
{
|
||||
strncpy(buffer, msg, buf_len);
|
||||
}
|
||||
```
|
||||
|
||||
The first parameter exec_env must be defined using type **wasm_exec_env_t** which is the calling convention for exporting native API by WAMR.
|
||||
|
||||
The rest parameters should be in the same types as the parameters of WASM function foo(), but there are a few special cases that are explained in section "Buffer address conversion and boundary check". Regarding the parameter names, they don't have to be the same, but we would suggest using the same names for easy maintenance.
|
||||
|
||||
|
||||
|
||||
#### Step 3: Register the native APIs
|
||||
|
||||
Register the native APIs in the runtime, then everything is fine. It is ready to build the runtime software.
|
||||
|
||||
``` C
|
||||
// Define an array of NativeSymbol for the APIs to be exported.
|
||||
// Note: the array must be static defined since runtime
|
||||
// will keep it after registration
|
||||
static NativeSymbol native_symbols[] =
|
||||
{
|
||||
{
|
||||
"foo", // the name of WASM function name
|
||||
foo_native, // the native function pointer
|
||||
"(ii)i" // the function prototype signature
|
||||
},
|
||||
{
|
||||
"foo2", // the name of WASM function name
|
||||
foo2, // the native function pointer
|
||||
"($*~)" // the function prototype signature
|
||||
}
|
||||
};
|
||||
|
||||
// ensure the memory and runtime initialization is finsihed
|
||||
// before registering the native functions
|
||||
bh_memory_init_with_pool(global_heap_buf, sizeof(global_heap_buf));
|
||||
wasm_runtime_init();
|
||||
|
||||
int n_native_symbols = sizeof(native_symbols) / sizeof(NativeSymbol);
|
||||
if (!wasm_runtime_register_natives("env",
|
||||
native_symbols,
|
||||
n_native_symbols)) {
|
||||
goto fail1;
|
||||
}
|
||||
|
||||
// natives registeration must be done before loading WASM modules
|
||||
module = wasm_runtime_load(buffer, size, error_buf, sizeof(error_buf));
|
||||
|
||||
```
|
||||
|
||||
**Function signature**:
|
||||
|
||||
The function signature field in **NativeSymbol** structure is a string for describing the function prototype. It is critical to ensure the function signature is correctly mapping the native function interface.
|
||||
|
||||
Each letter in the "()" represents a parameter type, and the one following after ")" represents the return value type. The meaning of each letter:
|
||||
|
||||
- 'i': i32
|
||||
- 'I': i64
|
||||
- 'f': f32
|
||||
- 'F': f64
|
||||
- '*': the parameter is a buffer address in WASM application
|
||||
- '~': the parameter is the byte length of WASM buffer as referred by preceding argument "\*". It must follow after '*', otherwise, registration will fail
|
||||
- '$': the parameter is a string in WASM application
|
||||
|
||||
**Use EXPORT_WASM_API_WITH_SIG**
|
||||
|
||||
The above foo2 NativeSymbol element can be also defined with macro EXPORT_WASM_API_WITH_SIG. This macro can be used when the native function name is the same as the WASM symbol name.
|
||||
|
||||
```c
|
||||
static NativeSymbol native_symbols[] =
|
||||
{
|
||||
EXPORT_WASM_API_WITH_SIG(foo2, "($*~)")
|
||||
};
|
||||
```
|
||||
|
||||
**Security attention:** A WebAssembly application should only have access to its own memory space. As a result, the integrator should carefully design the native function to ensure that the memory accesses are safe. The native API to be exported to the WASM application must:
|
||||
|
||||
|
||||
- Only use 32 bits number for parameters
|
||||
- Should not pass data to the structure pointer (do data serialization instead)
|
||||
- Should do the pointer address conversion in the native API
|
||||
- Should not pass function pointer as callback
|
||||
## Call exported API in wasm application
|
||||
|
||||
|
||||
|
||||
Below is a sample of a library extension. All code invoked across WASM and native world must be serialized and de-serialized, and the native world must do a boundary check for every incoming address from the WASM world.
|
||||
|
||||
In wasm world:
|
||||
``` C
|
||||
void api_send_request(request_t * request, response_handler_f response_handler,
|
||||
void * user_data)
|
||||
{
|
||||
int size;
|
||||
char *buffer;
|
||||
transaction_t *trans;
|
||||
|
||||
if ((trans = (transaction_t *) malloc(sizeof(transaction_t))) == NULL) {
|
||||
printf(
|
||||
"send request: allocate memory for request transaction failed!\n");

Steps for exporting native API
|
||||
==========================
|
||||
|
||||
WAMR implemented a framework for developers to export API's. Below is the procedure to expose the platform API's in three steps:
|
||||
|
||||
|
||||
## Step 1: Define the native API for exporting
|
||||
|
||||
Define the function **example_native_func** in your source file, namely `example.c` here:
|
||||
``` C
|
||||
int example_native_func(wasm_exec_env_t exec_env,
|
||||
int arg1, int arg2)
|
||||
{
|
||||
// Your implementation here
|
||||
}
|
||||
```
|
||||
The first function argument must be defined using type **wasm_exec_env_t** which is the WAMR calling convention for native API exporting.
|
||||
|
||||
The function prototype should also be declared in a header file so the wasm application can include it.
|
||||
``` C
|
||||
#ifndef _EXAMPLE_H_
|
||||
#define _EXAMPLE_H_
|
||||
#ifdef __cplusplus
|
||||
extern "C" {
|
||||
#endif
|
||||
|
||||
void example_native_func(int arg1, int arg2);
|
||||
|
||||
#ifdef __cplusplus
|
||||
}
|
||||
#endif
|
||||
#endif
|
||||
```
|
||||
|
||||
## Step 2: Declare the native API exporting
|
||||
|
||||
Declare the function **example_native_func** with macro **EXPORT_WASM_API** in your **.inl** file, namely `example.inl` in this sample.
|
||||
``` C
|
||||
EXPORT_WASM_API(example_native_func),
|
||||
```
|
||||
|
||||
Then include the file **example.inl** in definition of array **extended_native_symbol_defs** in the `ext_lib_export.c`.
|
||||
``` C
|
||||
static NativeSymbol extended_native_symbol_defs[] = {
|
||||
#include "example.inl"
|
||||
};
|
||||
|
||||
#include "ext_lib_export.h"
|
||||
```
|
||||
|
||||
|
||||
## Step 3: Compile the runtime product
|
||||
Add the source file **example.c** and **ext_lib_export.c** into the CMakeList.txt for building runtime with the exported API's:
|
||||
``` cmake
|
||||
set (EXT_API_SOURCE example.c)
|
||||
|
||||
add_executable (sample
|
||||
# other source files
|
||||
# ......
|
||||
${EXT_API_SOURCE}
|
||||
ext_lib_export.c
|
||||
)
|
||||
```
|
||||
|
||||
# Use exported API in wasm application
|
||||
|
||||
We can call the exported native API **example_native_func** in wasm application like this:
|
||||
Now we can call the exported native API in wasm application like this:
|
||||
``` C
|
||||
#include <stdio.h>
|
||||
#include "example.h"
|
||||
#include "example.h" // where the APIs are declared
|
||||
|
||||
int main(int argc, char **argv)
|
||||
{
|
||||
int a = 0, b = 1;
|
||||
char * msg = "hello";
|
||||
char buffer[100];
|
||||
|
||||
int c = foo(a, b); // call into native foo_native()
|
||||
foo2(msg, buffer, sizeof(buffer)); // call into native foo2()
|
||||
|
||||
example_native_func(a, b);
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Buffer address conversion and boundary check
|
||||
|
||||
A WebAssembly sandbox ensures applications only access to its own memory with a private address space. When passing a pointer address from WASM to native, the address value must be converted to native address before the native function can access it. It is also the native world's responsibility to check the buffer length is not over its sandbox boundary.
|
||||
|
||||
|
||||
|
||||
The signature letter '$', '\*' and '\~' help the runtime do automatic address conversion and buffer boundary check, so the native function directly uses the string and buffer address. **Notes**: if '\*' is not followed by '\~', the native function should not assume the length of the buffer is more than 1 byte.
|
||||
|
||||
|
||||
|
||||
As function parameters are always passed in 32 bits numbers, you can also use 'i' for the pointer type argument, then you must do all the address conversion and boundary checking in your native function. For example, if you change the foo2 signature to "(iii)", then you will implement the native part as the following sample:
|
||||
|
||||
```c
|
||||
void foo2(wasm_exec_env_t exec_env,
|
||||
uint32 msg_offset,
|
||||
uint32 buffer_offset,
|
||||
int32 buf_len)
|
||||
{
|
||||
wasm_module_inst_t module_inst = get_module_inst(exec_env);
|
||||
char *buffer;
|
||||
char * msg ;
|
||||
|
||||
// do boundary check
|
||||
if (!wasm_runtime_validate_app_str_add(msg_offset))
|
||||
return 0;
|
||||
|
||||
if (!wasm_runtime_validate_app_addr(buffer_offset, buf_len))
|
||||
return;
|
||||
|
||||
// do address conversion
|
||||
buffer = wasm_runtime_addr_app_to_native(buffer_offset);
|
||||
msg = wasm_runtime_addr_app_to_native(msg_offset);
|
||||
|
||||
strncpy(buffer, msg, buf_len);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Sandbox security attention
|
||||
|
||||
The runtime builder should ensure not broking the memory sandbox when exporting the native function to WASM.
|
||||
|
||||
A few key ground rules:
|
||||
|
||||
- Never pass any structure/class object pointer to native (do data serialization instead)
|
||||
- Do the pointer address conversion in the native API if "$\*" is not used for the pointer in the function signature
|
||||
- Never pass a function pointer to the native
|
||||
|
||||
|
||||
|
||||
## Pass structured data or class object
|
||||
|
||||
We must do data serialization for passing structured data or class objects between the two worlds of WASM and native. There are two serialization methods available in WASM as below, and yet you can introduce more like json, cbor etc.
|
||||
|
||||
- [attributes container](../core/app-framework/app-native-shared/attr_container.c)
|
||||
- [restful request/response](../core/app-framework/app-native-shared/restful_utils.c)
|
||||
|
||||
Note the serialization library is separately compiled into WASM and runtime. And the source files are located in the folder "[core/app-framework/app-native-shared](../core/app-framework/app-native-shared)“ where all source files will be compiled into both worlds.
|
||||
|
||||
|
||||
|
||||
The following sample code demonstrates WASM app packs a response structure to buffer, then pass the buffer pointer to the native:
|
||||
|
||||
```c
|
||||
/*** file name: core/app-framework/base/app/request.c ***/
|
||||
|
||||
void api_response_send(response_t *response)
|
||||
{
|
||||
int size;
|
||||
char * buffer = pack_response(response, &size);
|
||||
if (buffer == NULL)
|
||||
return;
|
||||
|
||||
wasm_response_send(buffer, size); // calling exported native API
|
||||
free_req_resp_packet(buffer);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
|
||||
The following code demonstrates the native API unpack the WASM buffer to local native data structure:
|
||||
|
||||
```c
|
||||
/*** file name: core/app-framework/base/native/request_response.c ***/
|
||||
|
||||
bool
|
||||
wasm_response_send(wasm_exec_env_t exec_env, char *buffer, int size)
|
||||
{
|
||||
if (buffer != NULL) {
|
||||
response_t response[1];
|
||||
|
||||
if (NULL == unpack_response(buffer, size, response))
|
||||
return false;
|
||||
|
||||
am_send_response(response);
|
||||
|
||||
return true;
|
||||
}
|
||||
|
||||
return false;
|
||||
}
|
||||
```
|
||||

||||

# SDK for Wasm Micro Runtime
|
||||
This folder contains some tools to generate sdk for wamr runtime and wasm applications, the script and cmake files here are called by `make`, don't use them manually.
|
||||
# WebAssembly Micro Runtime SDK
|
||||
|
||||
|
||||
**Note**: [WASI-SDK](https://github.com/CraneStation/wasi-sdk/releases) version 7 and above should be installed before building the WAMR SDK.
|
||||
|
||||
|
||||
|
||||
### SDK profile and configuration file
|
||||
|
||||
A SDK profile presents a configuration of build parameters for the selection of CPU architecture, software platforms, execution mode, libc and application framework components. The profile configurations are saved in a cmake file that will be included by the WAMR SDK building tool `build_sdk.sh`.
|
||||
|
||||
Here is the default configuration file [wamr-sdk/wamr_config_default.cmake](./wamr_config_default.cmake):
|
||||
|
||||
## Build the SDK
|
||||
``` Bash
|
||||
cd ${WAMR_ROOT}/wamr-sdk
|
||||
make config
|
||||
```
|
||||
Following the prompt to finish the settings for your customized runtime and app sdk, then you will get `out` folder under `${WAMR_ROOT}`
|
||||
|
||||
The structure of the output folder is like bellow:
|
||||
set (WAMR_BUILD_PLATFORM "linux")
|
||||
set (WAMR_BUILD_TARGET X86_64)
|
||||
set (WAMR_BUILD_INTERP 1)
|
||||
set (WAMR_BUILD_AOT 1)
|
||||
set (WAMR_BUILD_JIT 0)
|
||||
set (WAMR_BUILD_LIBC_BUILTIN 1)
|
||||
set (WAMR_BUILD_LIBC_WASI 0)
|
||||
set (WAMR_BUILD_APP_FRAMEWORK 1)
|
||||
set (WAMR_BUILD_APP_LIST WAMR_APP_BUILD_BASE)
|
||||
```
|
||||
out
|
||||
|--app-sdk/
|
||||
| |--sysroot/
|
||||
| |--wamr_toolchain.cmake
|
||||
|
|
||||
|--runtime-sdk/
|
||||
|--include
|
||||
|--lib
|
||||
|--wamr_config.cmake
|
||||
|
||||
|
||||
|
||||
Execute following command to build the WAMR SDK for a configuration profile:
|
||||
|
||||
```
|
||||
### app-sdk usage
|
||||
The `app-sdk` is used to develop wasm applications, if your project are built with cmake, then the `wamr_toolchain.cmake` file is what you need to compile your project into wasm bytecode.
|
||||
|
||||
### runtime-sdk usage
|
||||
The `runtime-sdk` is used to help you embed WAMR runtime into your product easier. There are two method you can use the SDK:
|
||||
|
||||
1. Use the provided `runtime_lib.cmake` file:
|
||||
|
||||
You can include `${WAMR_ROOT}/cmake/runtime_lib.cmake` in your project's `CMakeLists.txt` file:
|
||||
``` cmake
|
||||
include (${WAMR_ROOT}/cmake/runtime_lib.cmake)
|
||||
add_library (vmlib ${WAMR_RUNTIME_LIB_SOURCE})
|
||||
# ......
|
||||
target_link_libraries (your_target vmlib -lm -ldl -lpthread)
|
||||
cd wamr-sdk
|
||||
./build_sdk.sh -n [profile name] -x [config file path]
|
||||
```
|
||||
2. Use the pre-built static library:
|
||||
|
||||
The output directory structure of a SDK package with profile name "simple":
|
||||
|
||||
```
|
||||
simple/
|
||||
├── app-sdk
|
||||
│ ├── libc-builtin-sysroot
|
||||
│ │ ├── include
|
||||
│ │ └── share
|
||||
│ └── wamr-app-framework
|
||||
│ ├── include
|
||||
│ │ ├── bi-inc
|
||||
│ │ └── wa-inc
|
||||
│ ├── lib
|
||||
│ └── share
|
||||
└── runtime-sdk
|
||||
├── include
|
||||
│ └── bi-inc
|
||||
└── lib
|
||||
```
|
||||
|
||||
|
||||
|
||||
Like the WAMR samples, a project probably has its own pre-defined SDK configuration file. The project building script can call the `build_sdk.sh` by passing the configuration file name to the build_sdk.sh to generate its own WAMR SDK package.
|
||||
|
||||
|
||||
|
||||
### Menu configuration for building SDK
|
||||
|
||||
Menu configuration is supported for easy integration of runtime components and application libraries for the target architecture and platform. Run following command to start the menu config.
|
||||
|
||||
```
|
||||
cd wamr-sdk
|
||||
./build_sdk.sh -i -n [profile name]
|
||||
```
|
||||
|
||||
The argument "-i" will make the command enter menu config mode as depicted below.
|
||||
|
||||
<img src="../doc/pics/wamr_menu_config.png" alt="wamr build menu configuration" style="zoom:80%;" />
|
||||
|
||||
After the menu configuration is finished, the profile config file is saved and the building process is automatically started. When the building gets successful, the SDK package is generated under folder $wamr-sdk/out/{profile}, and the header files of configured components were copied into the SDK package.
|
||||
|
||||
|
||||
|
||||
### Build WASM applications with APP-SDK
|
||||
|
||||
The folder “**app-sdk**” under the profile output directory contains all the header files and WASM library for developing the WASM application. For C/C++ based WASM applications, the developers can use conventional cross-compilation procedure to build the WASM application. According to the profile selection of libc, following cmake toolchain files under folder [wamr-sdk/app](./app) are available for cross compiling WASM application:
|
||||
|
||||
- ` wamr_toolchain.cmake`
|
||||
- `wasi_toolchain.cmake`
|
||||
|
||||
|
||||
|
||||
Refer to [build WASM applications](./doc/build_wasm_app.md) for the details.
|
||||
|
||||
|
||||
|
||||
### Use Runtime SDK to build native application
|
||||
|
||||
The output folder "**runtime-sdk**" contains all the header files and library files for integration with project native code.
|
||||
|
||||
You can link the pre-built library:
|
||||
``` cmake
|
||||

You can refer to this sample: [CMakeLists.txt](../samples/simple/CMakeLists.txt).
|
||||
|
||||
> NOTE: If you are familiar with how to configure WAMR by cmake and don't want to build the SDK, you can set the related settings on the top of your `CMakeLists.txt`, then the `runtime_lib.cmake` will not load settings from the SDK.

|
||||
