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 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(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.

RETURN VALUE

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