=head1 NAME
apparmor_parser - loads AppArmor profiles into the kernel
=head1 SYNOPSIS
B<apparmor_parser [-adrR] [--add] [--debug] [--replace] [--remove]
[--preprocess] [--Include n] [--base n] [ --Complain ]>
B<apparmor_parser [-hv] [--help] [--version]>
=head1 DESCRIPTION
B<apparmor_parser> is used to import new apparmor.d(5) profiles
into the Linux kernel. The profiles restrict the operations available
to processes by executable name.
The profiles are loaded into the Linux kernel by the B<apparmor_parser>
program, which takes its input from standard input. The input supplied to
B<apparmor_parser> should be in the format described in apparmor.d(5).
=head1 OPTIONS
=over 4
=item -a, --add
Insert the AppArmor definitions given into the kernel. This is the default
action. This gives an error message if a AppArmor definition by the same
name already exists in the kernel, or if the parser doesn't understand
its input. It reports when an addition succeeded.
=item -r, --replace
This flag is required if an AppArmor definition by the same name already
exists in the kernel; used to replace the definition already
in the kernel with the definition given on standard input.
=item -R, --remove
This flag is used to remove an AppArmor definition already in the kernel.
Note that it still requires a complete AppArmor definition as described
in apparmor.d(5) even though the contents of the definition aren't
used.
=item -C, --Complain
For the profile to load in complain mode.
=item -B, --binary
Load a binary (cached) profile, as produced with the -S option.
=item -N, --names
Produce a list of policies from a given set of profiles (implies -K).
=item -S, --stdout
Writes a binary (cached) profile to stdout (implies -K and -T).
=item -b n, --base n
Set the base directory for resolving #include directives
defined as relative paths.
=item -I n, --Include n
Add element n to the search path when resolving #include directives
defined as an absolute paths.
=item -f n, --subdomainfs n
Set the location of the apparmor security filesystem (default is
"/sys/kernel/security/apparmor").
=item -m n, --match-string n
Only use match features "n".
=item -n n, --namespace-string n
Force a profile to load in the namespace "n".
=item -X, --readimpliesX
In the case of profiles that are loading on systems were READ_IMPLIES_EXEC
is set in the kernel for a given process, load the profile so that any "r"
flags are processed as "mr".
=item -k, --show-cache
Report the cache processing (hit/miss details) when loading or saving
cached profiles.
=item -K, --skip-cache
Perform no caching at all: disables -W, implies -T.
=item -T, --skip-read-cache
By default, if a profile's cache is found in /etc/apparmor.d/cache/ and
the timestamp is newer than the profile, it will be loaded from the cache.
This option disables this cache loading behavior.
=item -W, --write-cache
Write out cached profiles to /etc/apparmor.d/cache/. Off by default.
In cases where abstractions have been changed, and the parser is running
with "--replace", it may make sense to also use "--skip-read-cache" with
the "--write-cache" option.
=item -Q, --skip-kernel-load
Perform all actions except the actual loading of a profile into the kernel.
This is useful for testing profile generation, caching, etc, without making
changes to the running kernel profiles.
=item -q, --quiet
Do not report on the profiles as they are loaded, and not show warnings.
=item -v, --verbose
Report on the profiles as they are loaded, and show warnings.
=item -V, --version
Print the version number and exit.
=item -p, --preprocess
Dump the input profile to stdout out applying preprocessing flattening
includes into the output profile.
=item -d, --debug
Given once, only checks the profiles to ensure syntactic correctness.
Given twice, dumps its interpretation of the profile for checking.
=item -h, --help
Give a quick reference guide.
