Confirmed conntracks can be read locklessly,\nso adding an extension may reallocate and free the extension block\nwhile another CPU accesses it.\n\nOnly add the extension for unconfirmed conntracks.  A confirmed\nconntrack without labels now fails the caller's label operation instead\nof reallocating its extension storage.",
