This is papering over the real bug; I'll post a saner fix shortly. The real problem is BS hiding of ima_file_free() inside a hook, with condition that kinda-sorta happens to avoid bogus call most of the time. ima_path_check() side is also of BUG_ON() variety (and isn't triggered). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
