Describe the bug

Hi, i encountered an error in rt_thread_mdelay function.

Describe the bug

Incorrect message handling or mailbox state causes kernel stop in tcpip thread

Steps to reproduce

1.Build RT-Thread 2.Use the following command to start the kernel with QEMU:

qemu-system-arm \
    -M vexpress-a9 \
    -smp 2 \
    -m 4096M \
    -kernel /path/to/rt-thread/bsp/qemu-vexpress-a9/rtthread.bin \
    -drive if=sd,file=/path/to/rt-thread/bsp/qemu-vexpress-a9/sd.bin,format=raw \
    -nographic \
    -semihosting \

3.Use the functions and parameters provided in the ’Test case‘ section for testing

Source code location

/root/rtthread/rt-thread/components/net/lwip/port/sys_arch.c : sys_arch_mbox_fetch : 423 :

    /*When the waiting msg is generated by the application through signaling mechanisms,
    only by using interruptible mode can the program be made runnable again*/
    ret = rt_mb_recv_interruptible(*mbox, (rt_ubase_t *)msg, t); // 423
    if(ret != RT_EOK)
    {
        return SYS_ARCH_TIMEOUT;
    }

Test case

syz_thread_delay_ms()

long syz_thread_delay_ms(volatile int ms) {
    if (ms <= 0) {
        return -1;
    }
    rt_thread_mdelay((rt_int32_t)ms);
    return 0;
}
