Link with -lapparmor when compiling.
Additionally, a D-Bus method is available:
The aa_getcon function gets the current AppArmor confinement context
for the current task. The confinement context is usually just the name
of the AppArmor profile restricting the task, but it may include the
profile namespace or in some cases a set of profile names (known as a
stack of profiles). The returned string *con should be freed using
free(), but the returned string *mode should not be freed. The *con and
*mode strings come from a single buffer allocation and are separated by
a NUL character.
The aa_gettaskcon function is like the aa_getcon function except it
will work for any arbitrary task in the system.
The aa_getpeercon function is similar to that of aa_gettaskcon except
that it returns the confinement information for task on the other end
of a socket connection.
The aa_getpeercon_raw function is the backend for the aa_getpeercon
function and does not handle buffer allocation.
The aa_getprocattr function is the backend for the aa_getcon and
aa_gettaskcon functions and handles the reading and parsing of the
confinement data from different arbitrary attr files and returns the
processed results in an allocated buffer.
The aa_getprocattr_raw() is the backend for the aa_getprocattr function
and does not handle buffer allocation.
The org.freedesktop.DBus.GetConnectionAppArmorSecurityContext() D-Bus
method gets the AppArmor confinement string associated with the unique
connection name. If D-Bus is not performing AppArmor mediation, the
org.freedesktop.DBus.Error.AppArmorSecurityContextUnknown error is
On success size of data placed in the buffer is returned, this includes
the mode if present and any terminating characters. On error, -1 is
returned, and errno(3) is set appropriately.
The apparmor kernel module is not loaded or the communication via
the /proc/*/attr/file did not conform to protocol.
Insufficient kernel memory was available.
Access to the specified file/task was denied.
The specified file/task does not exist or is not visible.
The confinement data is too large to fit in the supplied buffer.
If aa_getpeercon_raw returns -1 and errno is ERANGE, the value of *len
can be used to reallocate buf so that it is sufficiently large enough
to store the confinement data.
