RDMA/uverbs: Add empty rdma_uattrs_has_raw_cap() declaration

2025-08-15T14:39:06Z

[ Upstream commit 98269398c02ab20eb9ed6d77416023a2627049d8 ] The call to rdma_uattrs_has_raw_cap() is placed in mlx5 fs.c file, which is compiled without relation to CONFIG_INFINIBAND_USER_ACCESS. Despite the check is used only in flows with CONFIG_INFINIBAND_USER_ACCESS=y|m, the compilers generate the following error for CONFIG_INFINIBAND_USER_ACCESS=n builds. >> ERROR: modpost: "rdma_uattrs_has_raw_cap" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined!

RDMA/uverbs: Check CAP_NET_RAW in user namespace for flow create

2025-08-15T14:39:02Z

[ Upstream commit f458ccd2aa2c5a6f0129a9b1548f2825071fdc6b ] Currently, the capability check is done in the default init_user_ns user namespace. When a process runs in a non default user namespace, such check fails. Due to this when a process is running using Podman, it fails to create the flow resource. Since the RDMA device is a resource within a network namespace, use the network namespace associated with the RDMA device to determine its owning user namespace.

RDMA/ipoib: Use parent rdma device net namespace

2025-08-15T14:39:02Z

[ Upstream commit f1208b05574f63c52e88109d8c75afdf4fc6bf42 ] Use the net namespace of the underlying rdma device. After honoring the rdma device's namespace, the ipoib netdev now also runs in the same net namespace of the rdma device. Add an API to read the net namespace of the rdma device so that ULP such as IPoIB can use it to initialize its netdev.

IB/cm: Remove dead code and adjust naming

2025-05-25T10:24:21Z

Drop ib_send_cm_mra parameters which are always constant. Remove branch which is never taken. Adjust name to ib_prepare_cm_mra, which better reflects its functionality - no MRA is actually sent. Adjust name of related tracepoints. Push setting of the constant service timeout to cm.c and drop IB_CM_MRA_FLAG_DELAY.
