       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, *.dpkg-remove, *.pacsave, *.pacnew, *.rpmnew,
       *.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 profiles.

       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 etc).

       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 -K).

       -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 succeeded.

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

       --policy-features n
           Specify the feature set that the policy was developed under. This does not override
           feature ABI rules.

       --override-policy-abi n
           Specify the feature set that the policy was developed under and override any feature
           ABI rules that the policy may be using.

       --kernel-features n
           Specify the feature set of the kernel that the policy is being compiled for. If not
           specified this will be determined by the system's kernel.

       -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 used.

           Note: this sets both the --kernel-features and --policy-features to be the same.

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

           Note: this sets both the --kernel-features and --policy-features to be the same.

       -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 behavior.

       -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(s) of the cache directory. This option can accept a comma separated
           list of directories, which will be searched in order to find a matching cache. The
           first matching cache file found is used even if a directory later in the search order
           may contain a newer cache file.

           If multiple directories are specified and --write-cache has been specified then cache
           writes will be made to the first directory in the list, all other directories will be
           treated as read only.

           If a cache directory name needs to have a comma as part of the name, it can be
           specified by using a backslash to escape the comma character in the directory name.

           If not specified the cache location defaults to /var/cache/apparmor

           Print the cache directory location. This path will be a subdirectory of the directory
           specified by --cache-loc. The subdirectory used will be influenced by the features
           available in the currently running kernel or by the features specified with the
           --match-string or --features-file options.

       -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 warnings.

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

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

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

           A specific warning can be disabled by prepending no- to the flag

             apparmor_parser --warn=no-rules-not-enforced ...

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

           Convert warnings into errors during policy compilation. If the optional flag is not
           specified all warnings become errors. If the optional flag is specified only the class
           of warnings specified will become errors. A single flag can be specified per --Werror
           option, but the --Werror flag can be passed multiple times.

             apparmor_parser --Werror=deprecated ...

           Use --help=warn or --help=Werror to see a full list of which warn flags are supported.

       -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 supported

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

             0    - disable jobs and use the main process for all compilation
             #    - 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 cpus
             -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. Note that if jobs is a positive
           integer number the --jobs-max parameter is automatically set to the same value.

       --max-jobs n
           When --jobs is set to a scaling value (ie. auto or xN) the specify 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
           reasonable 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.

           Specify the config file to use instead of /etc/apparmor/parser.conf. This option will
           be processed early before regular options regardless of the order it is specified in.

           Print the config file location that will be used.


       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 others.

       All other options override previously set values.
