[RFC PATCH 08/12] drm/fabric: add provisioning netlink uAPI

From: Ilia Levi <[email protected]>

Extend the YNL specification with six privileged provisioning commands.

FABRIC_NEW and FABRIC_DEL create and delete empty userspace-owned
fabrics; FABRIC_NEW carries a fabric-new-params nest with the type, name
and instance ID. ENDPOINT_SET changes fabric membership and endpoint
administrative state, PORT_SET changes port administrative state, and
PORT_PEER_NEW and PORT_PEER_DEL manage peer adjacency. All six require
GENL_ADMIN_PERM.

A peer request carries its type-qualified identity and far-end port
index. The descriptor is stored without resolving it to a local object,
as documented in Documentation/gpu/drm-fabric.rst.

Add an endpoint-change notification and extend the existing port-change
and peer notifications to cover userspace-requested transitions.

Generate the headers from the tree root with:

  tools/net/ynl/pyynl/ynl_gen_c.py --mode uapi --header \
      --spec Documentation/netlink/specs/drm_fabric.yaml \
      -o include/uapi/drm/drm_fabric.h
  tools/net/ynl/pyynl/ynl_gen_c.py --mode kernel --header \
      --spec Documentation/netlink/specs/drm_fabric.yaml \
      -o drivers/gpu/drm/fabric/drm_fabric_nl.h

The generated source names the six doit handlers, so it lands with their
implementation in the next patch. Drop the temporary administrative-state
definitions now that the generated headers provide them.

 The family name on the wire is ``drm-fabric``.
 
+Provisioning
+============
+
+The provisioning interface requires ``CAP_NET_ADMIN``. ``fabric-new`` and
+``fabric-del`` are core-owned; the rest are serviced by the provider and
+return ``-EOPNOTSUPP`` where it does not implement the matching callback:
+
+* ``fabric-new`` -- create an empty, userspace-owned fabric. The request
+  carries a ``fabric-new-params`` nest with the fabric type, an optional name
+  and a provider-defined instance ID.
+* ``fabric-del`` -- delete an empty, userspace-owned fabric. Refuses a
+  provider-owned fabric (``-EPERM``) and a non-empty one (``-EBUSY``).
+* ``endpoint-set`` -- attach an orphan endpoint, selected by ``endpoint-id`` or
+  by its backing ``dev-name`` with an optional ``bus-name``, to a fabric;
+  detach it with ``fabric-id`` 0; and/or set its administrative state.
+* ``port-set`` -- set a port's administrative state.
+* ``port-peer-new`` / ``port-peer-del`` -- set or unset a port's neighbor
+  half-edge. Valid only on a userspace-managed port; a provider-managed port
+  returns ``-EOPNOTSUPP`` (see `Peer management mode`_).
+
+Mutation commands carry ``GENL_ADMIN_PERM`` and are additionally confined to
+``init_net``. ``GENL_ADMIN_PERM`` only checks ``CAP_NET_ADMIN`` in the caller's
+user namespace, which a process in a nested user and network namespace may
+hold; restricting mutators to ``init_net`` prevents container-local privilege
+from reconfiguring host-global topology.
+
+A userspace-created fabric additionally pins this module for as long as it
+remains registered: ``fabric-new`` takes the pin, ``fabric-del`` releases it.
+
+Peer management mode
+--------------------
+
+A port uses one peer-management mode, fixed by the provider at registration.
+
+In provider-managed mode, the provider reports peer creation and removal
+(drm_fabric_port_set_peer() / drm_fabric_port_unset_peer()) and userspace peer
+provisioning is unsupported (``port-peer-new`` / ``port-peer-del`` return
+``-EOPNOTSUPP``).
+
+In userspace-managed mode, peer creation and removal are requested through the
+provisioning API and the provider does not independently replace or retract the
+peer (drm_fabric_port_set_peer() / drm_fabric_port_unset_peer() return
+``-EOPNOTSUPP``).
+
+One authority per descriptor prevents concurrent updates from both sources.
+Setting an occupied port returns ``-EEXIST``; unsetting an empty port returns
+``-ENOENT``.
+
+Provisioning examples
+---------------------
+
+Provision with the in-tree YNL tool (root, initial namespace):
+
+.. code-block:: bash
+
+    # Create an empty fabric
+    ./tools/net/ynl/pyynl/cli.py \
+        --spec Documentation/netlink/specs/drm_fabric.yaml \
+        --do fabric-new \
+        --json '{"fabric-new-params": {"type": "synthetic", "instance-id": 42}}'
+
+The command returns a core-assigned ``fabric-id``. Use that value in the
+following requests.
+
+.. code-block:: bash
+
+    # Attach an orphan endpoint to the returned fabric
+    ./tools/net/ynl/pyynl/cli.py \
+        --spec Documentation/netlink/specs/drm_fabric.yaml \
+        --do endpoint-set \
