Move the property, all ops use the same header. This ensures YNL C sees the correct hdr_len: const struct ynl_family ynl_ovs_vport_family = { .name = "ovs_vport", - .hdr_len = sizeof(struct genlmsghdr), + .hdr_len = sizeof(struct genlmsghdr) + sizeof(struct ovs_header), }; Fixes: 7c59c9c8f202 ("tools: ynl: generate code for ovs families") Link: https://patch.msgid.link/20250409145541.580674-1-kuba@kernel.org Signed-off-by: Jakub Kicinski --- diff --git a/Documentation/netlink/specs/ovs_vport.yaml b/Documentation/netlink/specs/ovs_vport.yaml index 86ba9ac2a5210..b538bb99ee9b5 100644 --- a/Documentation/netlink/specs/ovs_vport.yaml +++ b/Documentation/netlink/specs/ovs_vport.yaml @@ -123,12 +123,12 @@ attribute-sets: operations: name-prefix: ovs-vport-cmd- + fixed-header: ovs-header list: - name: new doc: Create a new OVS vport attribute-set: vport - fixed-header: ovs-header do: request: attributes: @@ -141,7 +141,6 @@ operations: name: del doc: Delete existing OVS vport from a data path attribute-set: vport - fixed-header: ovs-header do: request: attributes: @@ -152,7 +151,6 @@ operations: name: get doc: Get / dump OVS vport configuration and state attribute-set: vport - fixed-header: ovs-header do: &vport-get-op request: attributes:
