security_set_boolean: routines for manipulating SELinux boolean values
security_set_boolean, security_commit_booleans, security_get_boolean_names, security_get_boolean_active, security_get_boolean_pending - routines for manipulating SELinux boolean values
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);
DESCRIPTIONThe 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_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. Note that the int permanent flag is deprecated and should be set to zero.
