Since commite9b9e4ace2has landed, there is a chance that container.RWLayer is nil (due to some half-removed container). Let's check the pointer before use to avoid any potential nil pointer dereferences, resulting in a daemon crash. Note that even without the abovementioned commit, it's better to perform an extra check (even it's totally redundant) rather than to have a possibility of a daemon crash. In other words, better be safe than sorry. [v2: add a test case for daemon.getInspectData] [v3: add a check for container.Dead and a special error for the case] Fixes:e9b9e4ace2Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
