The driver may sleep under a spin lock, and the function call path is: post_one_send (acquire the lock by spin_lock_irqsave) init_send_wqe copy_from_user --> may sleep There is no flow that makes "qp->is_user" true, and copy_from_user may cause bug when a non-user pointer is used. So the lines of copy_from_user and check of "qp->is_user" are removed.

Add 64KB PAGE_SIZE support to user-space CQ, SQ and RQ queues. De-facto it means that code was added to translate 64KB pages to smaller 4KB pages that the FW can handle. Otherwise, the FW would wrap (or jump to the next page) when reaching 4KB while the user space library will continue on the same large page. Note that MR code remains as is since the FW supports larger pages for MRs.

HW stalls out after 0x800000 WQEs are posted for UD QPs. To workaround this problem, driver will send a modify_qp cmd to the HW at around the halfway mark(0x400000) so that FW can accordingly modify the QP context in the HW to prevent this stall.

由 Roland Dreier 提交于
Commit eea40b8f ("infiniband: call ipv6 route lookup via the stub interface") introduced a regression in address resolution when connecting to IPv6 destination addresses. The old code called ip6_route_output(), while the new code calls ipv6_stub->ipv6_dst_lookup(). The two are almost the same, except that ipv6_dst_lookup() also calls ip6_route_get_saddr() if the source address is in6addr_any. This means that the test of ipv6_addr_any(&fl6.saddr) now never succeeds, and so we never copy the source address out. This ends up causing rdma_resolve_addr() to fail, because without a resolved source address, cma_acquire_dev() will fail to find an RDMA device to use. For me, this causes connecting to an NVMe over Fabrics target via RoCE / IPv6 to fail. Fix this by copying out fl6.saddr if ipv6_addr_any() is true for the original source address passed into addr6_resolve(). We can drop our call to ipv6_dev_get_saddr() because ipv6_dst_lookup() already does that work.

This change will optimize kernel memory deregistration operations. __ib_umem_release() used to call set_page_dirty_lock() against every writable page in its memory region. Its purpose is to keep data synced between CPU and DMA device when swapping happens after mem deregistration ops. Now we choose not to set page dirty bit if it's already set by kernel prior to calling __ib_umem_release().

ipoib_dev_init accesses the wrong private data for the IPoIB device. Commit cd565b4b (IB/IPoIB: Support acceleration options callbacks) changed ipoib_priv from being identical to netdev_priv to being an area inside of, but not the same pointer as, the netdev_priv pointer.

The cited patch added a type field to structures ib_ah and rdma_ah_attr. Function mlx4_ib_query_ah() builds an rdma_ah_attr structure from the data in an mlx4_ib_ah structure (which contains both an ib_ah structure and an address vector). For mlx4_ib_query_ah() to work properly, the type field in the contained ib_ah structure must be set correctly. In the outgoing MAD tunneling flow, procedure mlx4_ib_multiplex_mad() paravirtualizes a MAD received from a slave and sends the processed mad out over the wire. During this processing, it populates an mlx4_ib_ah structure and calls mlx4_ib_query_ah(). The cited commit overlooked setting the type field in the contained ib_ah structure before invoking mlx4_ib_query_ah(). As a result, the type field remained uninitialized, and the rdma_ah_attr structure was incorrectly built. This resulted in improperly built MADs being sent out over the wire. This patch properly initializes the type field in the contained ib_ah structure before calling mlx4_ib_query_ah(). The rdma_ah_attr structure is then generated correctly.

The handling of IB_RDMA_WRITE_ONLY_WITH_IMMEDIATE will leak a memory reference when a buffer cannot be allocated for returning the immediate data. The issue is that the rkey validation has already occurred and the RNR nak fails to release the reference that was fruitlessly gotten. The the peer will send the identical single packet request when its RNR timer pops. The fix is to release the held reference prior to the rnr nak exit. This is the only sequence the requires both rkey validation and the buffer allocation on the same packet.
