As a result, the DMA API operates onmemory beyond the end of the allocation.\nThis was observed on a custom i.MX8MP platform with an mcp251xfd CANcontroller under heavy RPMSG load, as a series of refcount_t warningstriggered from rpmsg_recv_done() in virtio_rpmsg_bus:\n  refcount_t: addition on 0; use-after-free.  refcount_t: underflow; use-after-free.  refcount_t: saturated; leaking memory.\nLeading finally to an \"Unable to handle kernel paging request\" oops.Reproducing this problem took between 30 minutes and roughly 30 hoursunder the same workload.\nHardware watchpoints on the refcount of a struct rpmsg_endpoint showedit was overwritten from 2 to 1 by __pi_memcpy_generic() in theirq/155-spi2.0 thread. Additionally it was found that a \"normal\"rpmsg_recv_done() took 11\u00b5s +/-2\u00b5s from its kref_get to kref_put. Inthe error case the same sequence took about 215\u00b5s +/-10\u00b5s. Based onthis, an LLM was used to identify the size mismatch fixed here.\nAllocate the buffers with DMA_CACHE_ALIGNED_LEN(dma_len) so they coverthe full mapped length, and use the same length fordma_sync_single_for_cpu() to stay consistent with map and unmap.\nWith this patch applied, the same workload ran for more than 200 hourswithout the problem
