[BUG] out of memory on esp32s3 after running ls

[Y334275]

Description / Steps to reproduce the issue

Hi NuttX Community,
I encountered an "out of memory" error after building and flashing NuttX 12.12.0 (kernel mode) to an ESP32-S3. Here are the steps to reproduce the issue:

1. Build NuttX 12.12.0 in kernel mode.
2. Flash the resulting image to an ESP32-S3.
3. After the system boots, run the ls command couple times.

On which OS does this issue occur?

[OS: Linux]

What is the version of your OS?

Ubuntu 22.04.5 LTS

NuttX Version

12.12.0

After reviewing the code shown in the backtraces, I identified the root cause of the issue:

1. The fullpath variable in the nsh_script function is allocated on the kernel heap.
2. However, nsh_freefullpath calls a function to free this space from the user heap (mismatched heap allocation/deallocation).

The fullpath variable is returned by nsh_getfullpath, so I inspected that function. It uses strdup to duplicate the path—this is the critical flaw: strdup allocates memory on the kernel heap, but nsh_freefullpath incorrectly frees it from the user heap. Over time, this mismatch corrupts the kernel heap, leading to the out-of-memory error.

Fortunately, I have some familiarity with Xtensa. I checked the Newlib implementation and found the following code in arch/xtensa/src/esp32s3/es32s3_libc_stubs.c:

void *_malloc_r(struct _reent *r, size_t size)
{
  return lib_malloc(size);
}

void *_realloc_r(struct _reent *r, void *ptr, size_t size)
{
  return lib_realloc(ptr, size);
}

void *_calloc_r(struct _reent *r, size_t nmemb, size_t size)
{
  return lib_calloc(nmemb, size);
}

void _free_r(struct _reent *r, void *ptr)
{
  lib_free(ptr);
}

It appears that these implementations of _malloc_r/_realloc_r/_free_r/_calloc_r should call lib_umalloc/lib_ufree (user heap) instead of lib_malloc/lib_free (kernel heap) in this context.

These changes are tested in my environment, and they worked. I don’t know if they will cause other problems.

Hi,
Thanks for detailed explanation. We will take a look.

[eren-terzioglu]

For testing error properly, could you send defconfig output coming from make savedefconfig command?

[Y334275]

@eren-terzioglu Hi, here is my defconfig file:

I'm working with a custom board, but you can substitute it with esp32s3-devkit for testing purposes.
By the way, I'm building NuttX as part of PX4, rather than building NuttX directly. In this setup, NuttX is compiled in kernel mode.

Thanks for the information, I will check with this.
