NAME

       apparmor_parser - loads AppArmor profiles into the kernel

SYNOPSIS

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

       apparmor_parser [options] <command>

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

DESCRIPTION

       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, which by
       default takes its input from standard input. The input supplied to apparmor_parser should
       be in the format described in apparmor.d(5).

COMMANDS

       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

       --purge-cache
           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.

OPTIONS

       -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
           "/sys/kernel/security/apparmor").

       -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 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-bad-cache
           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 warnings.

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

       -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

       -O n, --optimize=n
           Set the optimization flags used by policy compilation.  A sinlge 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.

CONFIG FILE

       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 --).

       Eg.
           #comment

           optimize=no-expr-tree
           optimize=compress-fast

       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.

       Eg.
           Optimize=no-minimize
           Optimize=minimize

       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.
