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 apparmor_parser program, which takes
its input from standard input. The input supplied to apparmor_parser should be in the
format described in apparmor.d(5).
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
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.
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.
For the profile to load in complain mode.
Load a binary (cached) profile, as produced with the -S option.
Produce a list of policies from a given set of profiles (implies -K).
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)
-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
-f n, --subdomainfs n
Set the location of the apparmor security filesystem (default 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".
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
Report the cache processing (hit/miss details) when loading or saving cached profiles.
Perform no caching at all: disables -W, implies -T.
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.
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.
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.
Do not report on the profiles as they are loaded, and not show warnings.
Report on the profiles as they are loaded, and show warnings.
Print the version number and exit.
Dump the input profile to stdout out applying preprocessing flattening includes into
the output profile.
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.
Give a quick reference guide.
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
All other options override previously set values.
