Xiang Xiao 1280a2a8f9 Launch the initial task through task_spawn instead of nxtask_create 
to share the code with the code path of posix_spawn

Ville Juven 864bcf556e sched/nx_bringup: Set the initial stack size in kernel build as well 
After #7364 this now works, so use it for the init process. It makes sense
as the init process typically requires a big stack (due to init scripts).

Ville Juven 4c1b66246d env_dup: Fix copying of env between address environments 
If address environments are in use, it is not possible to simply
memcpy from from one process to another. The current implementation
of env_dup does precisely this and thus, it fails at once when it is
attempted between two user processes.

The solution is to use the kernel's heap as an intermediate buffer.
This is a simple, effective and common way to do a fork().

Obviously this is not needed for kernel processes.

Ville Juven 75afe491ad RISC-V: Prepare for CONFIG_BUILD_KERNEL 
- Thread context prior to system call needs to be preserved
- Allocate a kernel heap
 2022-03-18 18:20:12 +08:00
Ville Juven 50578dc501 Fix the initial idle tasks environment 
- User mode allocator was used for setting up the environment. This
  works in flat mode and probably in protected mode as well, as there
  is always a a single user allocator present
- This does not work in kernel mode, where each user task has its own
  heap allocator. Also, when the idle tasks environment is being set,
  no allocator is ready and the system crashes at once.

Fix this by using the group allocators instead:
- Idle task is a kernel task, so its group is privileged
- Add group_realloc
- Use the group_malloc/realloc functions instead of kumm_malloc
