From 0498c2d9984ed2ad75b1cd5ba6abfa1226742df5 Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Thu, 26 Jun 2025 21:58:07 +0300 Subject: [PATCH] RDMA/uverbs: Check CAP_NET_RAW in user namespace for QP create 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 QP. 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.
