Meet Patel 383e9adb82 feat(kasan): add Kernel Address Sanitizer (KASAN) support for ESP-IDF 
Add KASAN support for detecting heap memory safety bugs (buffer
overflows, underflows, use-after-free) at runtime using compiler
instrumentation and shadow memory. Gated behind
CONFIG_IDF_EXPERIMENTAL_FEATURES, with touch points kept to esp_system
and heap so other components stay untouched.

- Core runtime (esp_system/kasan.c, esp_kasan.h): nibble-based shadow
  memory in DRAM, poison/unpoison, per-access validation, and __asan_*
  stubs; hot-path stubs in IRAM so they stay valid with the flash cache
  off. Shadow init runs before heap bring-up.
- Heap integration (heap/heap_kasan*.c): alloc/free hooks add redzones,
  a quarantine FIFO, and shadow updates.
- Panic handling: disable checks once at the panic handler entry so
  backtrace and stack dumps can read redzones without nested reports.
- Build system: -fsanitize=kernel-address for app code, with HAL, SoC,
  esp_rom, SPI flash, esp_hw_support, bootloader_support, FreeRTOS, and
  heap internals excluded from instrumentation.
- Test app (tools/test_apps/system/kasan_test): Unity tests for
  overflow, underflow, use-after-free, and all sized __asan_* stubs,
  with halt and no-halt configurations.
- Docs: document KASAN in the heap memory debugging guide (EN and CN).

Erhan Kurubas 1dac8685db feat(tracing): add new component for tracing 2025-10-30 12:15:35 +01:00
Erhan Kurubas 2ef718fc29 change(app_trace): breaking changes related to destination selection 
- Destination selection is unified for SystemView and app_trace
- Destination param is removed from app_trace APIs
- Destinaiton and related configuration now can be override from users
  with a callback from system_init_fn

Guillaume Souchere 3ac6eeb7b6 change(docs): Remove heap_caps_check_integrity wrong behavior warning in ROM heap 
A patch will fix the behavior of heap_caps_check_integrity in the ROM implementation
of the heap component so the warning is not longer needed.

Daniel Mangum 647e7a2a71 fix: Replace deprecated flushregs alias with full gdb command 
Usage of `flushregs` in gdb will result in the following warning:

```
Warning: 'flushregs', an alias for the command 'maintenance flush register-cache', is deprecated.
Use 'maintenance flush register-cache'.
```

This patch updates to use the recommend command.
