ftp server upload filer error.

[jameszxj]

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)
{
/*
 * If we build not for the legacy network stack, then we use the 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.

Subject:  ftp server upload filer error.



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.
