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.

GFP_KERNEL may cause ida_alloc_range() to sleep, but the spinlock covering this function is not allowed to sleep, so the spinlock needs to be changed to mutex. As there is a certain chance of memory allocation failure, GFP_ATOMIC is not suitable for QP allocation scenarios.

The PVRDMA device HW interface defines network_hdr_type according to an old definition of the internal kernel rdma_network_type enum that has since changed, resulting in the wrong rdma_network_type being reported. Fix this by explicitly defining the enum used by the PVRDMA device and adding a function to convert the pvrdma_network_type to rdma_network_type enum.

Currently rtrs when create_qp use a coarse numbers (bigger in general), which leads to hardware create more resources which only waste memory with no benefits. - SERVICE con, For max_send_wr/max_recv_wr, it's 2 times SERVICE_CON_QUEUE_DEPTH + 2 - IO con For max_send_wr/max_recv_wr, it's sess->queue_depth * 3 + 1 Fixes: 6a98d71daea1 ("RDMA/rtrs: client: main functionality") Link: https://lore.kernel.org/r/20201217141915.56989-6-jinpu.wang@cloud.ionos.com Signed-off-by: Jack Wang <jinpu.wang@cloud.ionos.com> Reviewed-by: Md Haris Iqbal <haris.iqbal@cloud.ionos.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2021-01-15RDMA/rtrs: Extend ibtrs_cq_qp_createJack Wang4-12/+16
rtrs does not have same limit for both max_send_wr and max_recv_wr, To allow client and server set different values, export in a separate parameter for rtrs_cq_qp_create. Also fix the type accordingly, u32 should be used instead of u16.
