sorry, this problem is nothing to do with libbsd. The
rtems/cpukit/ftpd/ftpd.c add a new function yield(),
this function makes the problem.
static void
yield(void)
{
/*

libbsd. In
* the libbsd there is no global network stack semaphore which
provides round
* robin fairness for threads of equal priority.
*/
#ifndef RTEMS_NETWORKING
yield();
#endif
}
recursive invocation yield() make the function do not return. I use
rtems_task_wake_after(0) replace the yield,
ftp server works correctly.

hi,
I update libbsd to the github version, and when i upload a file, the
upload process failed at the end, and the target shell stuck.
I disconnect from the ftp client, shell print the msg
debug: _bsd_sonewconn: pcb 0x15df2000: Listen queue
overflow: 2 already in queue awaiting acceptance (1 occurrences)
The target still respond the ping command.
