2025-09-28smb: server: fix IRD/ORD negotiation with the clientStefan Metzmacher
Already do real negotiation in smb_direct_handle_connect_request() where we see the requested initiator_depth and responder_resources from the client. We should detect legacy iwarp clients using MPA v1 with the custom IRD/ORD negotiation. We need to send the custom IRD/ORD in big endian, but we need to try to let clients with broken requests using little endian (older cifs.ko) to work. Note the reason why this uses u8 for initiator_depth and responder_resources is that the rdma layer also uses it.

2025-09-28smb: client: let smbd_post_send_iter() call ib_dma_map_single() for the ↵Stefan Metzmacher
header first This will simplify further changes, the important part is that request->num_sge >= 1 is only set if request->sge[0].* is valid. Note that ib_dma_sync_single_for_device() is called in smbd_post_send() for each sge, so the device will still see the packet header even if it's modified after calling ib_dma_map_single().

2025-09-28smb: client: make consitent use of spin_lock_irq{save,restore}() in smbdirect.cStefan Metzmacher
There is a mix of using spin_lock(), spin_lock_irq() and spin_lock_irqsave() and it seems at least enqueue_reassembly() was wrong in using just spin_lock() as it's called via recv_done() from a SOFTIRQ as we're using IB_POLL_SOFTIRQ. And Documentation/kernel-hacking/locking.rst section "Cheat Sheet For Locking" says: - Otherwise (== data can be touched in an interrupt), use spin_lock_irqsave() and spin_unlock_irqrestore(). So in order to keep it simple and safe we use that version now. It will help merging functions into common code and have consistent locking in all cases.

2025-09-28smb: client: move rdma_readwrite_threshold from smbd_connection to ↵Stefan Metzmacher
TCP_Server_Info This belongs to the SMB layer not to the transport layer, it just uses the negotiated transport parameters to adjust the value if needed.

This will allow us to use common functions soon.

2025-09-28smb: client: remove unused smbd_connection.count_reassembly_queueStefan Metzmacher
This basically represents the same information as sc->recv_io.reassembly.queue_length. The only thing that's different is that smbd_connection.count_reassembly_queue was updated in each loop step, while sc->recv_io.reassembly.queue_length is only updated once after the loop in smbd_recv. Also sc->recv_io.reassembly.queue_length is updated under a spinlock.

There is only one protocol version for smbdirect yet and this variable is write only.
