[libc][libdl] Fix dlopen() failing to find already-loaded modules

2026-04-14T02:52:24Z

components: libc: fix reset static variable unsolved in dlmodule_load_shared_object

2026-03-12T05:59:15Z

[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

[libc/posix] Fix mq_send() to block when queue is full per POSIX standard

2026-02-24T05:39:05Z

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."

[components][clock_time] Refactor time subsystem around clock_time (#11111)

2026-01-31T09:44:27Z

* [components][clock_time] Refactor time subsystem around clock_time Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals. Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional. Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer. * [components][clock_time] Use BSP-provided clock timer frequency on riscv64 * [risc-v] Use runtime clock timer frequency for tick and delays * [bsp] Add clock timer frequency hooks for riscv64 boards * [bsp] Update Renesas RA driver doc clock_timer link * [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh * [bsp][rk3500] Update rk3500 clock configuration * [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays * [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci * [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings. * [bsp][raspi3] select clock time for systimer * [bsp][hpm5300evk] Trim trailing blank line * [bsp][hpm5301evklite] Trim trailing blank line * [bsp][hpm5e00evk] Trim trailing blank line * [bsp][hpm6200evk] Trim trailing blank line * [bsp][hpm6300evk] Trim trailing blank line * [bsp][hpm6750evk] Trim trailing blank line * [bsp][hpm6750evk2] Trim trailing blank line * [bsp][hpm6750evkmini] Trim trailing blank line * [bsp][hpm6800evk] Trim trailing blank line * [bsp][hpm6e00evk] Trim trailing blank line * [bsp][nxp] switch lpc178x to gcc and remove mcx timer source * [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue. * [docs][clock_time] add clock time documentation * [docs][clock_time] Update clock time subsystem documentation - Update device driver index to use correct page reference - Clarify upper layer responsibilities in architecture overview - Update README to describe POSIX/libc, Soft RTC, and device driver usage - Refine architecture diagram with improved layout and color scheme - Remove obsolete clock_timer.md file * [kernel][utest] Trim trailing space * [clock_time] Fix hrtimer wrap handling * [clock_time] fix the static rt_inline issue * [clock_time] fix the rt_clock_hrtimer_control result issue
