2021-01-20RDMA/umem: Support importing dma-buf as user memory regionJianxin Xiong4-1/+179
Dma-buf is a standard cross-driver buffer sharing mechanism that can be used to support peer-to-peer access from RDMA devices. Device memory exported via dma-buf is associated with a file descriptor. This is passed to the user space as a property associated with the buffer allocation. When the buffer is registered as a memory region, the file descriptor is passed to the RDMA driver along with other parameters. Implement the common code for importing dma-buf object and mapping dma-buf pages.

2021-01-20Revert "RDMA/rxe: Remove VLAN code leftovers from RXE"Martin Wilck2-0/+11
This reverts commit b2d2440430c0fdd5e0cad3efd6d1c9e3d3d02e5b. It's true that creating rxe on top of 802.1q interfaces doesn't work. Thus, commit fd49ddaf7e26 ("RDMA/rxe: prevent rxe creation on top of vlan interface") was absolutely correct. But b2d2440430c0 was incorrect assuming that with this change, RDMA and VLAN don't work togehter at all. It just has to be set up differently. Rather than creating rxe on top of the VLAN interface, rxe must be created on top of the physical interface. RDMA then works just fine through VLAN interfaces on top of that physical interface, via the "upper device" logic. This is hard to see in the rxe logic because it never talks about vlan, but instead rxe carefully selects upper vlan netdevices when working with packets which in turn imply certain vlan tagging. This is all done correctly and interacts with the gid table with VLAN support the same as real HW does. b2d2440430c0 broke this setup deliberately and should thus be reverted. Also, b2d2440430c0 removed rxe_dma_device(), so adapt the revert to discard that hunk.

2021-01-20RDMA/usnic: Fix misuse of sysfs_emit_atJoe Perches1-4/+3
In commit e28bf1f03b01 ("RDMA: Convert various random sprintf sysfs _show uses to sysfs_emit") I mistakenly used len = sysfs_emit_at to overwrite the last trailing space of potentially multiple entry output. Instead use a more common style by removing the trailing space from the output formats and adding a prefixing space to the contination formats and converting the final terminating output newline from the defective len = sysfs_emit_at(buf, len, "\n"); to the now appropriate and typical len += sysfs_emit_at(buf, len, "\n"); Fixes: e28bf1f03b01 ("RDMA: Convert various random sprintf sysfs _show uses to sysfs_emit") Link: https://lore.kernel.org/r/5eb794b9c9bca0494d94b2b209f1627fa4e7b555.camel@perches.com Reported-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
2021-01-20Revert "RDMA/mlx5: Fix devlink deadlock on net namespace deletion"Parav Pandit1-4/+2
This reverts commit fbdd0049d98d44914fc57d4b91f867f4996c787b. Due to commit in fixes tag, netdevice events were received only in one net namespace of mlx5_core_dev. Due to this when netdevice events arrive in net namespace other than net namespace of mlx5_core_dev, they are missed. This results in empty GID table due to RDMA device being detached from its net device. Hence, revert back to receive netdevice events in all net namespaces to restore back RDMA functionality in non init_net net namespace. The deadlock will have to be addressed in another patch.

2021-01-19RDMA/cxgb4: Fix the reported max_recv_sge valueKamal Heib1-1/+1
The max_recv_sge value is wrongly reported when calling query_qp, This is happening due to a typo when assigning the max_recv_sge value, the value of sq_max_sges was assigned instead of rq_max_sges. Fixes: 3e5c02c9ef9a ("iw_cxgb4: Support query_qp() verb") Link: https://lore.kernel.org/r/20210114191423.423529-1-kamalheib1@gmail.com Signed-off-by: Kamal Heib <kamalheib1@gmail.com> Reviewed-by: Potnuri Bharat Teja <bharat@chelsio.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
