The writeback worker follows the persisted dirty_tail chain, which is
\ndecoded from the cache device independently of the key_tail chain that
\ncache_replay() walks and bounds. A crafted image, whose on-media fields are
\nauthenticated only by a crc32c with a fixed seed, can aim dirty_tail at a
\nchain of last ksets that never terminates, so cache_writeback_fn() re-arms
\nitself with no delay forever.<\/p>\n
Walk the dirty_tail chain once at load with the same hop cap cache_replay()
\nuses and fail the table load with -EIO if it does not reach an end within
\nn_segs hops.<\/p>\n","protected":false},"excerpt":{"rendered":"
