Stefan Metzmacher 27bc4c57f0 smb: server: make only use of wake_up[_all]() in transport_rdma.c 
wake_up_interruptible(() doesn't wake up tasks waiting with wait_event().

So we better wake_up[_all]() in order to wake up all tasks in order
to simplify the logic.

As we currently don't use any wait_event_*_exclusive() it
doesn't really matter if we use wake_up() or wake_up_all().
But in this patch I try to use wake_up() for expected situations
and wake_up_all() for situations of a broken connection.
So don't need to adjust things in future when we
may use wait_event_*_exclusive() in order to wake up
only one process that should make progress.

Changing the wait_event_*() code in order to keep
wait_event(), wait_event_interruptible() and
wait_event_interruptible_timeout() or
changing them to wait_event_killable(),
wait_event_killable_timeout(),
wait_event_killable_exclusive()
is something to think about in a future patch.

The goal here is to avoid that some tasks are not
woken and freeze forever.

Also note that this patch only changes the existing
wake_up*() calls. Adding more wake_up*() calls for
other wait queues is also deferred to a future patch.

Stefan Metzmacher fad988a215 smb: server: fix IRD/ORD negotiation with the client 
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.

Stefan Metzmacher 2dad0b15bb smb: client: let smbd_post_send_iter() call ib_dma_map_single() for the 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().

Stefan Metzmacher a437c9cebc smb: client: make consitent use of spin_lock_irq{save,restore}() in smbdirect.c 
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.

Now struct smbd_connection only contains struct smbdirect_socket,
this is an important step towards having common functions as well.

This belongs to the SMB layer not to the transport layer, it
just uses the negotiated transport parameters to adjust the
value if needed.

Stefan Metzmacher 2449c7cc9b smb: client: remove unused smbd_connection.count_reassembly_queue 
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.
