NAME

       aa_getprocattr_raw, aa_getprocattr - read and parse procattr data

       aa_getcon, aa_gettaskcon - get task confinement information

       aa_getpeercon - get the confinement of a socket's other end (peer)

SYNOPSIS

       #include <sys/apparmor.h>

       int aa_getprocattr_raw(pid_t tid, const char *attr, char *buf, int len,
       char **mode);

       int aa_getprocattr(pid_t tid, const char *attr, char **buf, char **mode);

       int aa_gettaskcon(pid_t target, char **con, char **mode);

       int aa_getcon(char **con, char **mode);

       int aa_getpeercon(int fd, char **con);

       Link with -lapparmor when compiling.

DESCRIPTION

       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().

       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_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.

RETURN VALUE

       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.

ERRORS

       EINVAL
           The apparmor kernel module is not loaded or the communication via the
           /proc/*/attr/file did not conform to protocol.

       ENOMEM
           Insufficient kernel memory was available.

       EACCES
           Access to the specified file/task was denied.

       ENOENT
           The specified file/task does not exist or is not visible.

       ERANGE
           The confinement data is to large to fit in the supplied buffer.
