net: mctp: test: move TX packetqueue from dst to dev

2025-12-01T21:52:13+00:00

To capture TX packets during a test, we are currently intercepting the dst->output with an implementation that adds the transmitted packet to a skb queue attached to the test-specific mock dst. The netdev itself is not involved in the test TX path. Instead, we can just use our test device to stash TXed packets for later inspection by the test. This means we can include the actual mctp_dst_output() implementation in the test (by setting dst.output in the test case), and don't need to be creating fake dst objects, or their corresponding skb queues. We need to ensure that the netdev is up to allow delivery to ndo_start_xmit, but the tests assume active devices at present anyway.

net: Convert proto_ops connect() callbacks to use sockaddr_unsized

2025-11-05T03:10:32+00:00

Update all struct proto_ops connect() callback function prototypes from "struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the compiler about object sizes. Calls into struct proto handlers gain casts that will be removed in the struct proto conversion patch. No binary changes expected.

net: mctp: test: Add tests for gateway routes

2025-07-08T10:39:24+00:00

Add a few kunit tests for the gateway routing. Because we have multiple route types now (direct and gateway), rename mctp_test_create_route to mctp_test_create_route_direct, and add a _gateway variant too.

net: mctp: add gateway routing support

2025-07-08T10:39:24+00:00

This change allows for gateway routing, where a route table entry may reference a routable endpoint (by network and EID), instead of routing directly to a netdevice. We add support for a RTM_GATEWAY attribute for netlink route updates, with an attribute format of: struct mctp_fq_addr { unsigned int net; mctp_eid_t eid; } - we need the net here to uniquely identify the target EID, as we no longer have the device reference directly (which would provide the net id in the case of direct routes). This makes route lookups recursive, as a route lookup that returns a gateway route must be resolved into a direct route (ie, to a device) eventually. We provide a limit to the route lookups, to prevent infinite loop routing. The route lookup populates a new 'nexthop' field in the dst structure, which now specifies the key for the neighbour table lookup on device output, rather than using the packet destination address directly.
