NAME

       elksemu - Embedded Linux Kernel Subset emulator


SYNOPSIS

       /lib/elksemu program [arguments]


DESCRIPTION

       Elksemu  is  a  program  that allows 8086 ELKS programs to be run under
       Linux-i386. These programs can be compiled using the bcc(1) C compiler.

       Yom  may  use  the  binfmt-misc module under Linux 2.1.43 or greater as
       described in the elksemu README which will  cause  the  kernel  to  run
       elksemu  with  the correct arguments whenever the user tries to execute
       an ELKS executable directly.



OPTIONS

       There are no flag options to elksemu, the first argument is the name of
       the  program  to run the rest are arguments that are passed to the Elks
       program.



SECURITY

       The elksemu program may be installed suid-root and in this event it  is
       able to run execute only (chmod 111) elks executables and act correctly
       on the  suid  permission  bits  on  any  executable.   This  should  be
       considered  a  security hazard so elksemu does not have to be installed
       suid-root.  If you consider using this  facility  you  should  also  be
       aware that it will override the ’nosuid’ mount(8) option.

BUGS

       Elksemu is incomplete.

       The program may still have security bugs!
