Implement event sending for IB device rename and IB device port associated netdevice rename. In iproute2, rdma monitor displays the IB device name, port and the netdevice name when displaying event info. Since users can modiy these names, we track and notify on renaming events. Note: In order to receive netdevice rename events, drivers must use the ib_device_set_netdev() API when attaching net devices to IB devices. $ rdma monitor $ rmmod mlx5_ib [UNREGISTER] dev 1 rocep8s0f1 [UNREGISTER] dev 0 rocep8s0f0 $ modprobe mlx5_ib [REGISTER] dev 2 mlx5_0 [NETDEV_ATTACH] dev 2 mlx5_0 port 1 netdev 4 eth2 [REGISTER] dev 3 mlx5_1 [NETDEV_ATTACH] dev 3 mlx5_1 port 1 netdev 5 eth3 [RENAME] dev 2 rocep8s0f0 [RENAME] dev 3 rocep8s0f1 $ devlink dev eswitch set pci/0000:08:00.0 mode switchdev [UNREGISTER] dev 2 rocep8s0f0 [REGISTER] dev 4 mlx5_0 [NETDEV_ATTACH] dev 4 mlx5_0 port 30 netdev 4 eth2 [RENAME] dev 4 rdmap8s0f0 $ echo 4 > /sys/class/net/eth2/device/sriov_numvfs [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 2 netdev 7 eth4 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 3 netdev 8 eth5 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 4 netdev 9 eth6 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 5 netdev 10 eth7 [REGISTER] dev 5 mlx5_0 [NETDEV_ATTACH] dev 5 mlx5_0 port 1 netdev 11 eth8 [REGISTER] dev 6 mlx5_1 [NETDEV_ATTACH] dev 6 mlx5_1 port 1 netdev 12 eth9 [RENAME] dev 5 rocep8s0f0v0 [RENAME] dev 6 rocep8s0f0v1 [REGISTER] dev 7 mlx5_0 [NETDEV_ATTACH] dev 7 mlx5_0 port 1 netdev 13 eth10 [RENAME] dev 7 rocep8s0f0v2 [REGISTER] dev 8 mlx5_0 [NETDEV_ATTACH] dev 8 mlx5_0 port 1 netdev 14 eth11 [RENAME] dev 8 rocep8s0f0v3 $ ip link set eth2 name myeth2 [NETDEV_RENAME] netdev 4 myeth2 $ ip link set eth1 name myeth1 ** no events received, because eth1 is not attached to an IB device ** Signed-off-by: Chiara Meiohas <cmeiohas@nvidia.com> Link: https://patch.msgid.link/093c978ef2766fd3ab4ff8798eeb68f2f11582f6.1730367038.git.leon@kernel.org Signed-off-by: Leon Romanovsky <leon@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
