NAME¶
security_class_to_string, security_av_perm_to_string, string_to_security_class,
string_to_av_perm, security_av_string - convert between SELinux class and
permission values and string names.
print_access_vector - display an access vector in human-readable form.
SYNOPSIS¶
#include <selinux/selinux.h>
#include <selinux/flask.h>
const char * security_class_to_string(security_class_t
tclass);
const char * security_av_perm_to_string(security_class_t
tclass, access_vector_t av);
int security_av_string(security_class_t tclass, access_vector_t
av, char **result);
security_class_t string_to_security_class(const char
*name);
access_vector_t string_to_av_perm(security_class_t tclass,
const char *name);
void print_access_vector(security_class_t tclass,
access_vector_t av);
DESCRIPTION¶
security_class_to_string returns a string name for class
tclass,
or NULL if the class is invalid. The returned string must not be modified or
freed.
security_av_perm_to_string returns a string name for the access vector
bit
av of class
tclass, or NULL if either argument is invalid.
The returned string must not be modified or freed.
security_av_string computes a full access vector string representation
using
tclass and
av, which may have multiple bits set. The
string is returned in the memory pointed to by
result, and should be
freed by the caller using
free(3).
string_to_security_class returns the class value corresponding to the
string name
name, or zero if no such class exists.
string_to_av_perm returns the access vector bit corresponding to the
string name
name and security class
tclass, or zero if no such
value exists.
print_access_vector displays an access vector in human-readable form on
the standard output stream.
RETURN VALUE¶
security_av_string returns zero on success or -1 on error with
errno set appropriately.
print_access_vector does not return a
value. All other functions return zero or NULL on error.
ERRORS¶
- EINVAL
- A class or access vector argument is not recognized by the
currently loaded policy.
- ENOMEM
- An attempt to allocate memory failed.
