NAME
       getkeycreatecon, setkeycreatecon - get or set the SELinux security context used for creating a new kernel keyrings.

SYNOPSIS
       #include <selinux/selinux.h>

       int getkeycreatecon(security_context_t *con);

       int setkeycreatecon(security_context_t context);

DESCRIPTION
       getkeycreatecon	retrieves  the context used for creating a new kernel keyring.	This returned context should be freed with freecon if non-
       NULL.  getkeycreatecon sets *con to NULL if no keycreate context has been explicitly set by the program	(i.e.  using  the  default  policy
       behavior).

       setkeycreatecon	sets  the  context  used for creating a new kernel keyring.  NULL can be passed to setkeycreatecon to reset to the default
       policy behavior.  The keycreate context is automatically reset after the next execve, so a program doesn't need to explicitly  sanitize	it
       upon startup.

       setkeycreatecon	can be applied prior to library functions that internally perform an file creation, in order to set an file context on the
       objects.

       Note: Signal handlers that perform an setkeycreate must take care to save, reset, and restore the keycreate  context  to  avoid	unexpected
       behavior.

RETURN VALUE
       On error -1 is returned.  On success 0 is returned.
