       apparmor_parser - loads AppArmor profiles into the kernel


       apparmor_parser [options] <command> [profiles]...

       apparmor_parser [options] <command>

       apparmor_parser [-hv] [--help] [--version]


       apparmor_parser is used as a general tool to compile, and manage
       AppArmor policy, including loading new apparmor.d(5) profiles into the
       Linux kernel.

       AppArmor profiles restrict the operations available to processes.

       The profiles are loaded into the Linux kernel by the apparmor_parser
       program. The profiles may be specified by file name or a directory name
       containing a set of profiles. If a directory is specified then the
       apparmor_parser will try to do a profile load for each file in the
       directory that is not a dot file, or explicitly black listed
       (*.dpkg-new, *.dpkg-old, *.dpkg-dist, *-dpkg-bak, *.repnew, *.rpmsave,
       *orig, *.rej, *~). The apparmor_parser will fall back to taking input
       from standard input if a profile or directory is not supplied.

       The input supplied to apparmor_parser should be in the format described
       in apparmor.d(5).


       The command set is broken into four subcategories.

       unprivileged commands
           Commands that don't require any privilege and don't operate on

       unprivileged profile commands
           Commands that operate on a profile either specified on the command
           line or read from stdin if no profile was specified.

       privileged commands
           Commands that require the MAC_ADMIN capability within the affected
           AppArmor namespace to load policy into the kernel or filesystem
           write permissions to update the affected privileged files (cache

       privileged profile commands
           Commands that require privilege and operate on profiles.

Unprivileged commands

       -V, --version
           Print the version number and exit.

       -h, --help
           Give a quick reference guide.

Unprivileged profile commands

       -N, --names
           Produce a list of policies from a given set of profiles (implies

       -p, --preprocess
           Apply preprocessing to the input profile(s) by flattening includes
           into the output profile and dump to stdout.

       -S, --stdout
           Writes a binary (cached) profile to stdout (implies -K and -T).

       -o file, --ofile file
           Writes a binary (cached) profile to the specified file (implies -K
           and -T)

Privileged commands

           Unconditionally clear out cached profiles.

Privileged profile commands

       -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

       -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.

       -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.


       -B, --binary
           Treat the profile files specified on the command line (or stdin if
           none specified) as binary cache files, produced with the -S or -o
           options, and load to the kernel as specified by -a, -r, and -R
           (implies -K and -T).

       -C, --Complain
           Force the profile to load in complain mode.

       -b n, --base n
           Set the base directory for resolving #include directives defined as
           relative paths.

       -I n, --Include n
           Add element n to the search path when resolving #include directives
           defined as an absolute paths.

       -f n, --subdomainfs n
           Set the location of the apparmor security filesystem (default is

       -M n, --features-file n
           Use the features file located at path "n" (default is
           /etc/apparmor.d/cache/.features). If the --cache-loc option is
           present, the ".features" file in the specified cache directory is

       -m n, --match-string n
           Only use match features "n".

       -n n, --namespace-string n
           Force a profile to load in the namespace "n".

       -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".

       -k, --show-cache
           Report the cache processing (hit/miss details) when loading or
           saving cached profiles.

       -K, --skip-cache
           Perform no caching at all: disables -W, implies -T.

       -T, --skip-read-cache
           By default, if a profile's cache is found in the location specified
           by --cache-loc and the timestamp is newer than the profile, it will
           be loaded from the cache. This option disables this cache loading

       -W, --write-cache
           Write out cached profiles to the location specified in --cache-loc.
           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.

           Skip updating the cache if it contains cached profiles in a bad or
           inconsistent state

       -L, --cache-loc
           Set the location of the cache directory.  If not specified the
           cache location defaults to /etc/apparmor.d/cache

       -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.

           This also removes the need for privilege to execute the commands
           that manage policy in the kernel

       -q, --quiet
           Do not report on the profiles as they are loaded, and not show

       -v, --verbose
           Report on the profiles as they are loaded, and show warnings.

           Enable various warnings during policy compilation. A single dump
           flag can be specified per --warn option, but the --warn flag can be
           passed multiple times.

             apparmor_parser --warn=rules-not-enforced ...

           Use --help=warn to see a full list of which warn flags are

       -d, --debug
           Given once, only checks the profiles to ensure syntactic
           correctness.  Given twice, dumps its interpretation of the profile
           for checking.

       -D n, --dump=n
           Debug flag for dumping various structures and passes of policy
           compilation.  A single dump flag can be specified per --dump
           option, but the dump flag can be passed multiple times.  Note
           progress flags tend to also imply the matching stats flag.

             apparmor_parser --dump=dfa-stats --dump=trans-stats <file>

           Use --help=dump to see a full list of which dump flags are

       -j n, --jobs=n
           Set the number of jobs used to compile the specified policy. Where
           n can be

             #    - a specific number of jobs
             auto - the # of cpus in the in the system
             x#   - # * number of cpus

             -j8     OR --jobs=8                   allows for 8 parallel jobs
             -jauto  OR --jobs=auto                sets the jobs to the # of
             -jx4    OR --jobs=x4                  sets the jobs to # of cpus
           * 4
             -jx1   is equivalent to   -jauto

           The default value is the number of cpus in the system.

       --max-jobs n
           Set a hard cap on the value that can be specified by the --jobs
           flag.  It takes the same set of options available to the --jobs
           option, and defaults to 8*cpus

       -O n, --optimize=n
           Set the optimization flags used by policy compilation.  A single
           optimization flag can be toggled per -O option, but the optimize
           flag can be passed multiple times.  Turning off some phases of the
           optimization can make it so that policy can't complete compilation
           due to size constraints (it is entirely possible to create a dfa
           with millions of states that will take days or longer to compile).

           Note: The parser is set to use a balanced default set of flags,
           that will result in resonable compression but not take excessive
           amounts of time to complete.

           Use --help=optimize to see a full list of which optimization flags
           are supported.

       --abort-on-error Abort processing of profiles on the first error
       encountered, otherwise the parser will continue to try to compile other
       profiles if specified.
           Note: If an error is encountered while processing profiles the last
           error encountered will be used to set the exit code.

       --skip-bad-cache-rebuild The default behavior of the parser is to check
       if a cached version of a profile exists and if it does it attempt to
       load it into the kernel. If that load is rejected, then the parser will
       attempt to rebuild the cache file, and load again.
           This option tells the parser to not attempt to rebuild the cache on
           failure, instead the parser continues on with processing the
           remaining profiles.


       An optional config file /etc/apparmor/parser.conf can be used to
       specify the default options for the parser, which then can be
       overridden using the command line options.

       The config file ignores leading whitespace and treats lines that begin
       with # as comments.  Config options are specified one per line using
       the same format as the longform command line options (without the
       preceding --).



       As with the command line some options accumulate and others override,
       ie. when there are conflicting versions of switch the last option is
       the one chosen.


       would result in Optimize=minimize being set.

       The Include, Dump, and Optimize options accululate except for the
       inversion option (no-X vs. X), and a couple options that work by
       setting/clearing multiple options (compress-small).  In that case the
       option will override the flags it sets but will may accumulate with

       All other options override previously set values.
