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