This can lead to stale mappings and resource leaks.\n\nFix this by introducing a common cleanup helper that unmaps all\npreviously mapped iov entries before returning from error paths.\n\nAdditionally, track the actual mapped length of each iov entry\nexplicitly. This is necessary because some hashing flows may apply\npadding during processing, and the resulting buffer length used later\nin the flow can differ from the original DMA mapped length. Using the\nmodified length during dma_memory_unmap() may result in an incorrect\nunmap size.\n\nNote: this patch series is based on \nhttps://patchew.org/QEMU/20260504213421.710035-1-clg@redhat.com/.\n\nBest Regards,\nKane\n\nKane-Chen-AS (1):\n aspeed/hace: Fix mapped address may not be unmapped issue\n\n hw/misc/aspeed_hace.c | 63 ++++++++++++++++++++++++++++++-------------\n 1 file changed, 45 insertions(+), 18 deletions(-)"}
