When reading a RDMA WRITE FIRST packet we copy the DMA length from the RDMA header into the qp->resp.resid variable for later use. Later in check_rkey() we clamp it to the MTU if the packet is an RDMA WRITE packet and has a residual length bigger than the MTU. Later in write_data_in() we subtract the payload of the packet from the residual length. If the packet happens to have a payload of exactly the MTU size we end up with a residual length of 0 despite the packet not being the last in the conversation. When the next packet in the conversation arrives, we don't have any residual length left and thus set the QP into an error state. This broke NVMe over Fabrics functionality over rdma_rxe.ko The patch was verified using the following test. # echo eth0 > /sys/module/rdma_rxe/parameters/add # nvme connect -t rdma -a 192.168.155.101 -s 1023 -n nvmf-test # mkfs.xfs -fK /dev/nvme0n1 meta-data=/dev/nvme0n1 isize=256 agcount=4, agsize=65536 blks = sectsz=4096 attr=2, projid32bit=1 = crc=0 finobt=0, sparse=0 data = bsize=4096 blocks=262144, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 # mount /dev/nvme0n1 /tmp/ [ 148.923263] XFS (nvme0n1): Mounting V4 Filesystem [ 148.961196] XFS (nvme0n1): Ending clean mount # dd if=/dev/urandom of=test.bin bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes (134 MB, 128 MiB) copied, 0.437991 s, 306 MB/s # sha256sum test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a test.bin # cp test.bin /tmp/ sha256sum /tmp/test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a /tmp/test.bin Signed-off-by:Johannes Thumshirn <jthumshirn@suse.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Sagi Grimberg <sagi@grimberg.me> Cc: Max Gurtovoy <maxg@mellanox.com> Acked-by:

When the bit 26 of capmask2 field in OPA classport info query is set, SA will query for OPA path records instead of querying for IB path records. Note that OPA path records can only be queried by kernel ULPs. Userspace clients continue to query IB path records. Reviewed-by:

sa_path_rec now contains a union of sa_path_rec_ib and sa_path_rec_roce based on the type of the path record. Note that fields applicable to path record type ROCE v1 and ROCE v2 fall under sa_path_rec_roce. Accessor functions are added to these fields so the caller doesn't have to know the type. Reviewed-by:

struct sa_path_rec has a gid_type field. This patch introduces a more generic path record specific type 'rec_type' which is either IB, ROCE v1 or ROCE v2. The patch also provides conversion functions to get a gid type from a path record type and vice versa Reviewed-by:

rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created. This ensures that calls such as modify_ah dont modify the type of the address handle attribute. Reviewed-by:

SA will query and cache class port info as part of its initialization. SA will also invalidate and refresh the cache based on specific events. Callers such as IPoIB and CM can query the SA to get the classportinfo information. Apart from making the caller code much simpler, this change puts the onus on the SA to query and maintain classportinfo much like how it maitains the address handle to the SM. Reviewed-by:

The process_ecn intends to return a bool value. However it is doing so incorrectly by ANDing the fecn mask. The fecn bit is bit 31. Bool is not a native data type and is up to the compiler to implement how it sees fit. It is conceivable that this upper bit gets washed out. Fix by converting to a bool properly.
