  > This is a project to modify executables so that they do not have any
  > executable regions which are writable. If a section of an executable is
  > writable and executable, it is much easier for errant code to modify the
  > executable's behavior.
  > Two current areas in shared library environments which have this
  > critical problem are the GOT (Global Offset Table) and PLT (Procedure
  > Linkage Table). The PLT is required to be executable and both GOT and
  > PLT are writable on most architectures. On most ELF architecture
  > machines this would cause shared libraries to have data and BSS marked
  > as executable.
  > Padding to the linker script for programs and shared libraries/objects
  > to isolate the GOT and PLT into their own load sections in the
  > executables. This allows only the text(readonly) region and the PLT
  > region to be marked executable with the normal data and BSS not marked
  > as executable. The PLT region is still marked executable on most
  > architectures because the PLT lives in the "data" or "BSS" regions
  > and the dynamic loader will need to modify it. Since the GOT and PLT
  > should only ever be written by the dynamic linker, it will be modified
  > to mprotect those regions so that they are not writable during normal
  > execution. If the dynamic linker needs to modify the regions later,
  > (eg for lazy binding), it will mprotect the region, make the necessary
  > changes, and mprotect it back. Since it is possible to receive a
  > signal which would interrupt the program flow and perhaps cause the
  > dynamic linker to modify the same (or nearby) PLT references, it is now
  > necessary for signals to be blocked for the duration of the mprotect.

  > extends from _GLOBAL_OFFSET_TABLE_ to _DYNAMIC. Mostly from NetBSD.

  > Add a new option, -f, that allows the user to specify a custom output
  > format.  Currently only supports printing the inode number and path
  > (along with any arbitrary text) but other escapes may be added later.
  > A useful invocation is:
  > ncheck -s -f '\P\0' | xargs -0 ls -ldgT
