=head1 NAME

aa-status - display various information about the current AppArmor
policy.

=head1 SYNOPSIS

B<aa-status> [option]

=head1 DESCRIPTION

B<aa-status> will report various aspects of the current state of
AppArmor confinement. By default, it displays the same information as if
the I<--verbose> argument were given. A sample of what this looks like
is:

  apparmor module is loaded.
  110 profiles are loaded.
  102 profiles are in enforce mode.
  8 profiles are in complain mode.
  Out of 129 processes running:
  13 processes have profiles defined.
  8 processes have profiles in enforce mode.
  5 processes have profiles in complain mode.

Other argument options are provided to report individual aspects, to
support being used in scripts.

=head1 OPTIONS

B<aa-status> accepts only one argument at a time out of:

=over 4

=item --enabled

returns error code if AppArmor is not enabled.

=item --profiled

displays the number of loaded AppArmor policies.

=item --enforced

displays the number of loaded enforcing AppArmor policies.

=item --complaining

displays the number of loaded non-enforcing AppArmor policies.

=item --kill

displays the number of loaded enforcing AppArmor policies that will
kill tasks on policy violations.

=item --prompt

displays the number of loaded enforcing AppArmor policies, with
fallback to userspace mediation.

=item --special-unconfined

displays the number of loaded non-enforcing AppArmor policies that are
in the special unconfined mode.

=item --process-mixed
displays the number of processes confined by profile stacks with
profiles in different modes.

=item --verbose

displays multiple data points about loaded AppArmor policy
set (the default action if no arguments are given).

=item --json

displays multiple data points about loaded AppArmor policy
set in a JSON format, fit for machine consumption.

=item --pretty-json

same as --json, formatted to be readable by humans as well
as by machines.

=item --show

what data sets to show information about. Currently I<processes>,
I<profiles>, I<all> for both processes and profiles. The default is
I<all>.

=item --count

display only counts for selected information.

=item --filter.mode=filter

Allows specifying a posix regular expression filter that will be
applied against the displayed processess and profiles apparmor profile
mode, reducing the output.

=item --filter.profiles=filter

Allows specifying a posix regular expression filter that will be
applied against the displayed processess and profiles confining
profile, reducing the output.

=item --filter.pid=filter

Allows specifying a posix regular expression filter that will be
applied against the displayed processes, so that only processes pids
matching the expression will be displayed.

=item --filter.exe=filter

Allows specifying a posix regular expression filter that will be
applied against the displayed processes, so that only processes
executable name matching the expression will be displayed.

=item --help

displays a short usage statement.

=back

=head1 EXIT STATUS

Upon exiting, B<aa-status> will set its exit status to the
following values:

=over 4

=item B<0>

if apparmor is enabled and policy is loaded.

=item B<1>

if apparmor is not enabled/loaded.

=item B<2>

if apparmor is enabled but no policy is loaded.

=item B<3>

if the apparmor control files aren't available under
/sys/kernel/security/.

=item B<4>

if the user running the script doesn't have enough privileges to read
the apparmor control files.

=item B<42>

if an internal error occurred.

=back

=head1 BUGS

B<aa-status> must be run as root to read the state of the loaded
policy from the apparmor module. It uses the /proc filesystem to
determine which processes are confined and so is susceptible to race
conditions.
