kenneth.liu	cffaa514e2	components: libc: fix reset static variable unsolved in dlmodule_load_shared_object ... [Problem Description] In the dlmodule_load_shared_object function, if a module loading fails once due to an unresolved symbol, all subsequent attempts to load any module will fail. The system becomes unable to load modules correctly until a reboot. [Problem Analysis] The root cause is that the variable unsolved is defined as static. Static variables retain their value between function calls. If a relocation error occurs, unsolved is set to RT_TRUE. However, when the function returns with an error, the value of unsolved is not reset. Consequently, on the next function call, unsolved remains RT_TRUE from the previous execution. This causes the check if (unsolved) to trigger immediately (or after the loop), forcing the function to return an error regardless of whether the current module is valid or not. [Solution] Reset the unsolved variable to RT_FALSE before returning the error code -RT_ERROR. This ensures the variable is in a clean state for the next function call, preventing state leakage between invocations. Signed-off-by: Liu Gui <kenneth.liu@sophgo.com>	2026-03-12 13:59:15 +08:00
hzt	1b39e04687	[libc/posix] Fix mq_send() to block when queue is full per POSIX standard ... The POSIX mq_send() function currently passes timeout=0 to rt_mq_send_wait_prio(), causing it to return immediately when the queue is full instead of blocking as required by POSIX.1-2017. This patch: 1. Changes mq_send() to use RT_WAITING_FOREVER for blocking behavior 2. Implements mq_timedsend() properly with timeout support 3. Fixes errno mapping for different error conditions Reference: POSIX.1-2017 mq_send(3p): "If the specified message queue is full, mq_send() shall block until space becomes available to enqueue the message, or until mq_send() is interrupted by a signal."

kenneth.liu	4940bb1051	components: libc: fix pointer-to-integer cast warnings and address truncation ... [Problem Description] 1. When enabling RT_USING_MODULE=y, compilation warnings occur: dlelf.c:386:27: warning: cast from pointer to integer of different size dlelf.c:398:25: warning: cast from pointer to integer of different size dlelf.c:408:24: warning: cast from pointer to integer of different size 2. On RV64 architectures (e.g. Sophgo SG2042 with RISC-V Sv39 and 40-bit physical addressing), dlsym may fail when accessing addresses beyond 32-bit range. [Root Cause] In dlmodule_load_relocated_object() and dlmodule_symbol_find(), pointer is cast to rt_uint32_t which truncates: | rt_ubase_t rodata_addr = (rt_uint32_t)ptr; This causes: - Warnings on 64-bit systems (pointer width > 32-bit) - Actual address truncation on RV64 when physical address exceeds 32-bit [Solution] Replace rt_uint32_t with architecture-adaptive rt_ubase_t: | rt_ubase_t rodata_addr = (rt_ubase_t)ptr; The rt_ubase_t is defined in include/rttypes.h as: | #ifdef ARCH_CPU_64BIT | typedef rt_uint64_t rt_ubase_t; | #else | typedef rt_uint32_t rt_ubase_t; | #endif This ensures correct width casting for both 32/64-bit architectures.

kenneth.liu	a5b26bb588	components: libc: fix array overflow in rt_object name assignment ... [Problem Description] When assigning name to rt_object, strncpy() uses size equal to RT_NAME_MAX, which causes missing null-terminator and overflows into adjacent 'type' field. This corruption leads to unexpected system behavior. [Problem Analysis] The rt_object structure defines: | char name[RT_NAME_MAX] | -> buffer | rt_uint8_t type | -> adjacent field Original code calculates size as: size = end - first + 1; if (size > RT_NAME_MAX) size = RT_NAME_MAX; When size equals RT_NAME_MAX, strncpy() will copy exactly RT_NAME_MAX bytes without adding terminating '\0', causing two issues: 1. name buffer is not null-terminated 2. The implicit null-byte writes beyond name[] into type field [Solution] Change boundary check from: if (size > RT_NAME_MAX) size = RT_NAME_MAX; to: if (size >= RT_NAME_MAX) size = RT_NAME_MAX - 1; This ensures: 1. Always leaves space for null-terminator 2. Prevents overflow into type field 3. Maintains maximum valid name length (RT_NAME_MAX-1 + '\0') Signed-off-by: Liu Gui <kenneth.liu@sophgo.com>	2025-02-20 22:38:06 -05:00
