загрузить новую политику SELinux (load a new SELinux policy)
Имя (Name)
security_load_policy - load a new SELinux policy
Синопсис (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);
Описание (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(), internally determining the right
policy version, locating and opening the policy file, mapping it
into memory, manipulating it as needed for current boolean
settings and/or local definitions, and then calling
security_load_policy to load it. preservebools is a boolean flag
indicating whether current policy boolean values should be
preserved into the new policy (if 1) or reset to the saved policy
settings (if 0). The former case is the default for policy
reloads, while the latter case is an option for policy reloads
but is primarily used for the initial policy load.
selinux_init_load_policy() performs the initial policy load. This
function determines the desired enforcing mode, sets the enforce
argument accordingly for the caller to use, sets the SELinux
kernel enforcing status to match it, and loads the policy. It
also internally handles the initial selinuxfs mount required to
perform these actions.
It should also be noted that after the initial policy load, the
SELinux kernel code cannot anymore be disabled and the selinuxfs
cannot be unmounted using a call to security_disable(3).
Therefore, after the initial policy load, the only operational
changes are those permitted by security_setenforce(3) (i.e.
eventually setting the framework in permissive mode rather than
in enforcing one).
Возвращаемое значение (Return value)
Returns zero on success or -1 on error.
