NAME

       ausyscall - a program that allows mapping syscall names and numbers

SYNOPSIS

       ausyscall [arch] name | number | --dump | --exact

DESCRIPTION

       ausyscall is a program that prints out the mapping from syscall name to number and reverse
       for the given arch. The arch can be anything returned by `uname -m`. If arch is not given,
       the program will take a guess based on the running image. You may give the syscall name or
       number and it will find the opposite. You can also dump the whole table  with  the  --dump
       option.  By  default  a syscall name lookup will be a substring match meaning that it will
       try to match all occurrences of the given name with syscalls. So giving a  name  of  chown
       will  match  both  fchown  and  chown as any other syscall with chown in its name. If this
       behavior is not desired, pass the --exact flag and it will do an exact string match.

       This program can be used  to  verify  syscall  numbers  on  a  biarch  platform  for  rule
       optimization. For example, suppose you had an auditctl rule:

       -a always, exit -S open -F exit=-EPERM -k fail-open

       If  you wanted to verify that both 32 and 64 bit programs would be audited, run "ausyscall
       i386 open" and then "ausyscall x86_64 open". Look at the returned  numbers.  If  they  are
       different, you will have to write two auditctl rules to get complete coverage.

       -a always,exit -F arch=b32 -S open -F exit=-EPERM -k fail-open
       -a always,exit -F arch=b64 -S open -F exit=-EPERM -k fail-open

       For  more  information about a specific syscall, use the man program and pass the number 2
       as an argument to make sure that you get the  syscall  information  rather  than  a  shell
       script  program  or  glibc  function  call of the same name. For example, if you wanted to
       learn about the open syscall, type: man 2 open.

OPTIONS

       --dump Print all syscalls for the given arch

       --exact
              Instead of doing a partial word match, match the given syscall name exactly.
