       ausyscall - a program that allows mapping syscall names and numbers


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


       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.


       --dump Print all syscalls for the given arch

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


       ausearch(8), auditctl(8).
