             Bug #: 2145
           Summary: CONFIGURE_BDBUF_* macros should be range checked
    Classification: Unclassified
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: filesystem
        AssignedTo: chrisj at rtems.org
        ReportedBy: claus at SLAC.Stanford.edu

Setting :


causes bdbuf to allocate 1 MB of stack space, which is bigger than the size of
the standard stack.

Chris e-mailed me that "We should range check the value at start up and fail if
beyond a reasonable value."  Sebastian added "Yes, we should check that this
doesn't exceed 12.5% (off hand guess) of the threads minimum stack size."
