selinux_lsetfilecon_default – set the file context to the system defaults Synopsis #include <selinux/selinux.h> int selinux_lsetfilecon_default(const char *path); Description selinux_lsetfilecon_default() sets the file context to the system defaults. Return Value Returns zero on success or -1 otherwise. See Also selinux(8), selinux_file_context_cmp(3), selinux_file_context_verify(3), matchpathcon(3), freecon(3), setfilecon(3), setfscreatecon(3)

security_load_policy – load a new SELinux policy Synopsis #include <selinux/selinux.h> int security_load_policy(void *data, size_t len); int selinux_mkload_policy(int preservebools); int selinux_init_load_policy(int *enforce); Description security_load_policy() loads a new policy, returns 0 for success and -1 for error. selinux_mkload_policy() makes a policy image and loads it. This function provides a higher level interface for loading policy than security_load_policy(),…

selinux_getpolicytype – get the type of SELinux policy running on the system Synopsis #include <selinux/selinux.h> int selinux_getpolicytype(char **policytype); Description selinux_getpolicytype() Reads the contents of the /etc/selinux/config file to determine the SELinux policy used on the system, and sets policytype accordingly. Free policytype with free(3). Return Value On success, zero is returned. On failure, -1 is…

selinux_getenforcemode – get the enforcing state of SELinux Synopsis #include <selinux/selinux.h> int selinux_getenforcemode(int *enforce); Description selinux_getenforcemode() Reads the contents of the /etc/selinux/config file to determine how the system was setup to run SELinux. Sets the value of enforce to 1 if SELinux should be run in enforcing mode. Sets the value of enforce to 0…
