           Summary: tftp client does not timeout if
                    CONFIG_FEATURE_TFTP_PROGRESS_BAR=y
           Product: Busybox
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Networking
        AssignedTo: unassigned at busybox.net
        ReportedBy: francesco at dolcini.it

   Estimated Hours: 0.0


Tftp client timeout after a very long time (more than five minutes) and not in
the normal way if the progress bar is enabled (tested with busybox 1.8.1).

If the progress bar is enabled everything works just fine.

To reproduce just start a tftp download and unplug the network cable.

this is the expected behavior when progress bar is disabled:

tftp -g -r file.bin -l /tmp/aa 10.0.0.105
eth0: link down
tftp: timeout
