The aa_getcon function gets the current AppArmor confinement context for the
current task. The confinement context consists of a label and a mode. The
label 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 mode is a string that describes how
the kernel is enforcing the policy defined in the profile. Profiles loaded in
"enforce" mode will result in enforcement of the policy defined in
the profile as well as reporting policy violation attempts. Profiles in
"complain" mode will not enforce policy but instead report policy
Some examples of possible returned *label strings are "unconfined",
"/sbin/dhclient", and "Firefox". The string can consist of
any non-NUL characters but it will be NUL-terminated. The *label string must
be freed using free()
The possible *mode strings are "enforce" and "complain".
Additionally, *mode may be NULL when *label is "unconfined". The
*mode string must not be freed
. The *label 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
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
is the backend for the aa_getprocattr function
and does not handle buffer allocation.
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
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
