security_load_policy(3) 				     SELinux API documentation					   security_load_policy(3)

NAME

       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(), 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.  pre-
       servebools 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).

RETURN VALUE

       Returns zero on success or -1 on error.

NAME

       security_load_booleans,	security_set_boolean,  security_commit_booleans,  security_get_boolean_names,  security_get_boolean_active,  secu-
       rity_get_boolean_pending - routines for manipulating SELinux boolean values

SYNOPSIS

       #include <selinux/selinux.h>

       int security_load_booleans(char *path);

       int security_get_boolean_names(char ***names, int *len);

       int security_get_boolean_pending(const char *name);

       int security_get_boolean_active(const char *name);

       int security_set_boolean(const char *name, int value);

       int security_set_boolean_list(size_t boolcnt, SELboolean *boollist, int permanent);

       int security_commit_booleans(void);

DESCRIPTION

       The SELinux policy can include conditional rules that are enabled or disabled based on the current values of  a	set  of  policy  booleans.
       These policy booleans allow runtime modification of the security policy without having to load a new policy.

       The SELinux API allows for a transaction based update. So you can set several boolean values and then commit them all at once.

       security_load_booleans

       loads policy boolean settings. Path may be NULL, in which case the booleans are loaded from the active policy boolean configuration file.

       security_get_boolean_names

       provides a list of boolean names, currently supported by the loaded policy.

       security_get_boolean_pending

       returns the pending value for boolean or -1 on failure.

       security_get_boolean_active

       returns the active value for boolean or -1 on failure.

       security_set_boolean

       sets the pending value for boolean

       security_set_boolean_list

       saves a list of booleans in a single transaction.

       security_commit_booleans

       commits all pending values for the booleans.

RETURN VALUE

       Where not otherwise stated, functions described in this manual page return zero on success or -1 on error.
