getsockcreatecon() retrieves the context used for creating a new
labeled network socket. This returned context should be freed
with freecon(3) if non-NULL. getsockcreatecon() sets *con to
NULL if no sockcreate context has been explicitly set by the
program (i.e. using the default policy behavior).
setsockcreatecon() sets the context used for creating a new
labeled network sockets NULL can be passed to setsockcreatecon()
to reset to the default policy behavior. The sockcreate context
is automatically reset after the next execve(2), so a program
doesn't need to explicitly sanitize it upon startup.
setsockcreatecon() can be applied prior to library functions that
internally perform an file creation, in order to set an file
context on the objects.
getsockcreatecon_raw() and setsockcreatecon_raw() behave
identically to their non-raw counterparts but do not perform
Note: Signal handlers that perform a setsockcreatecon() must take
care to save, reset, and restore the sockcreate context to avoid
Note: Contexts are thread specific.
