Gerd Rausch a2db4a6ce8 net/rds: dma_map_sg is entitled to merge entries ... [ Upstream commit fb4b1373dc ] Function "dma_map_sg" is entitled to merge adjacent entries and return a value smaller than what was passed as "nents". Subsequently "ib_map_mr_sg" needs to work with this value ("sg_dma_len") rather than the original "nents" parameter ("sg_len"). This old RDS bug was exposed and reliably causes kernel panics (using RDMA operations "rds-stress -D") on x86_64 starting with: commit c588072bba ("iommu/vt-d: Convert intel iommu driver to the iommu ops") Simply put: Linux 5.11 and later.
