            Bug ID: 14616
           Summary: Printf format code and data type do not match in
                    taskset
           Product: Busybox
           Version: 1.33.x
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: pdvb at yahoo.com
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

The following code uses an (unsigned long) "%lx" format code, but passes an
(unsigned long long) value to printf.  The result is that on architectures
which use 32-bit for (unsigned long) and 64-bit for (unsigned long long) the
printf produces incorrect output.

#define TASKSET_PRINTF_MASK "%lx"
static unsigned long long from_mask(ul *mask, unsigned sz_in_bytes
UNUSED_PARAM)
{
        return *mask;
}


This was broken by commit ef0e76cc on 1/29/2017
The quick fix is to define the function as:

static unsigned long from_mask()
