2016-08-02iw_cxgb4: explicitly move the qp to ERROR state during flushSteve Wise
This forces the connection to abort if the application failed to disconnect before flushing. This is aligned with how the common flush services work. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-08-02iw_cxgb4: stop MPA_REPLY timer when disconnectingSteve Wise
There exists a race where the application can setup a connection and then disconnect it before iw_cxgb4 processes the fw4_ack message. For passive side connections, the fw4_ack message is used to know when to stop the ep timer for MPA_REPLY messages. If the application disconnects before the fw4_ack is handled then c4iw_ep_disconnect() needs to clean up the timer state and stop the timer before restarting it for the disconnect timer. Failure to do this results in a "timer already started" message and a premature stopping of the disconnect timer.

2016-08-02RDMA/cxgb3: Use AF_INET for sin_family fieldAmitoj Kaur Chawla
Elsewhere the sin_family field holds a value with a name of the form AF_..., so it seems reasonable to do so here as well. Also the values of PF_INET and AF_INET are the same. The Coccinelle semantic patch that makes this change is as follows: // <smpl> @@ struct sockaddr_in sip; @@ ( sip.sin_family == - PF_INET + AF_INET | sip.sin_family != - PF_INET + AF_INET | sip.sin_family = - PF_INET + AF_INET ) // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-08-02vhost: new device IOTLB APIJason Wang
This patch tries to implement an device IOTLB for vhost. This could be used with userspace(qemu) implementation of DMA remapping to emulate an IOMMU for the guest. The idea is simple, cache the translation in a software device IOTLB (which is implemented as an interval tree) in vhost and use vhost_net file descriptor for reporting IOTLB miss and IOTLB update/invalidation. When vhost meets an IOTLB miss, the fault address, size and access can be read from the file. After userspace finishes the translation, it writes the translated address to the vhost_net file to update the device IOTLB. When device IOTLB is enabled by setting VIRTIO_F_IOMMU_PLATFORM all vq addresses set by ioctl are treated as iova instead of virtual address and the accessing can only be done through IOTLB instead of direct userspace memory access. Before each round or vq processing, all vq metadata is prefetched in device IOTLB to make sure no translation fault happens during vq processing. In most cases, virtqueues are contiguous even in virtual address space. The IOTLB translation for virtqueue itself may make it a little slower. We might add fast path cache on top of this patch.

2016-08-02vhost: convert pre sorted vhost memory array to interval treeJason Wang
Current pre-sorted memory region array has some limitations for future device IOTLB conversion: 1) need extra work for adding and removing a single region, and it's expected to be slow because of sorting or memory re-allocation. 2) need extra work of removing a large range which may intersect several regions with different size. 3) need trick for a replacement policy like LRU To overcome the above shortcomings, this patch convert it to interval tree which can easily address the above issue with almost no extra work. The patch could be used for: - Extend the current API and only let the userspace to send diffs of memory table. - Simplify Device IOTLB implementation.
