NAME

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

SYNOPSIS

       #include <selinux/selinux.h>

       int getkeycreatecon(char **con);

       int getkeycreatecon_raw(char **con);

       int setkeycreatecon(char *context);

       int setkeycreatecon_raw(char *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.

       Note: Contexts are thread specific.

RETURN VALUE

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