cmake	cmake/nuttx_mkversion: quote NUTTX_VERSION_LIST to fix empty variable expansion When git tag output is empty, NUTTX_VERSION_LIST is an empty variable. Without quotes, string(REPLACE) expands to only 3 arguments instead of the required 4, causing a CMake error. Add quotes around ${NUTTX_VERSION_LIST} to ensure it is always passed as an argument even when empty. Signed-off-by: xuxin19 <xuxin19@xiaomi.com>	2 个月前
crypto	crypto/rijndael: fix undefined behavior in AES decryption last round Cast TD4 S-box lookup results to uint32_t before left shift by 24 to avoid signed integer overflow. When TD4 returns a value >= 128, shifting by 24 as signed int exceeds INT_MAX, triggering UBSan runtime error: "left shift of N by 24 places cannot be represented in type 'int'".

libs	Revert "libs/libc/stdlib/lib_exit.c: fix multiple definition of __dso_handle in msys2" This reverts commit 8f96e59aee9cd0c5bbb82e01044d109f8588fec2. The implementation of __dso_handle is independent of the HOST OS but dependent on the specific compiler. Therefore, this patch will cause compilation failures for other cross-compilers on the Windows platform, such as arm-none-eabi-gcc and aarch64-none-elf-gcc. Constraints should be applied to compiler target rather than compiler host. Signed-off-by: Shanmin Zhang <zhangshanmin@xiaomi.com>	2 个月前
mm	mm: Add double-free detection to delay list When same memory is freed twice and both added to delay list (race condition in interrupt context), it causes crash later in mm_forcefree() when processing the delay list. This patch adds early detection in add_delaylist() using: 1. Magic value (addr ^ 0xDEADBEEF) for O(1) fast path 2. List traversal for confirmation when magic matches The double-free will be caught immediately with DEBUGASSERT instead of crashing later in free_delaylist() Changes: - Add MM_DELAY_MAGIC and magic field to mm_delaynode_s - Implement two-step detection in add_delaylist() - Sync implementation across mm_heap and tlsf allocators Signed-off-by: ligd <liguiding1@xiaomi.com>	2 个月前

These functions are called by perf_gettime which is used in the instrument callback path, and must not be instrumented to avoid infinite recursion when CONFIG_ARCH_INSTRUMENT_ALL is enabled.

Apache NuttX 是一个实时操作系统（RTOS），着重于标准合规性和占用空间小。可扩展从 8 位到 64 位微控制器环境，NuttX 中的主要管理标准为 POSIX 和 ANSI 标准。对于这些标准下不可用或不适用于深度嵌入式环境（例如 fork()）的功能，NuttX 采用了 Unix 和其他常见 RTOS（如 VxWorks）的附加标准 API。

为了简洁，文档中的许多部分会将 Apache NuttX 简称为 NuttX。
