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 getkeycreatecon_raw(security_context_t *con);

       int setkeycreatecon(security_context_t context);

       int setkeycreatecon_raw(security_context_t context);

DESCRIPTION
       getkeycreatecon()  retrieves  the context used for creating a new kernel keyring.  This returned context should be freed with freecon(3) if
       non-NULL.  getkeycreatecon() sets *con to NULL if no keycreate context has been explicitly set by the program (i.e. using the default  pol-
       icy 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(2), 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.

       getkeycreatecon_raw() and setkeycreatecon_raw() behave identically to their non-raw counterparts but do not perform context translation.

       Note: Signal handlers that perform a setkeycreatecon() must take care to save, reset, and restore the keycreate context to avoid unexpected
       behavior.

       Note: Contexts are thread specific.

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