Subject:[PATCH] siw_cm: use to_sockaddr_in() also within dprint
For siw, the dma_device-bus is currently not set, which will cause
the crash.
As we were testing NFS/RDMA we just disabled that fix for some Mellanox
device.
I agree I probably have to find a more consistent way to fake real dma
hardware. Any suggestions?
Thanks,
Bernard.

Dear all,
many thanks for commenting on the software iWARP RDMA

Steve,
we currently do not support inline data for kernel clients since
we copy those data into a malloc'd buffer, where kmalloc()
might block. Using an explicit buffer comes from experiments
to allow for larger blocks of inlined data.
I could put the inline data directly into the wqe restricting

the post_send/recv and other functions in your driver are called
directly (almost) by kernel users like NFSRDMA. These users may be
calling in an interrupt context and thus you cannot block/sleep.

Agreed.
Currently, if running out of backlog, the cm actively
rejects the connection with -ENOMEM back to the provider
(see ucma_event_handler(), and cm_conn_req_handler()).
That should allow the provider to zap the TCP connection,
but its not very productive ;)

To my understanding, our discussion
On the other hand trying to hook offloaded iWARP into the normal

does seem to lead to a mess. I see DaveM's point: TCP port space is
just the beginning -- filtering, queueing, etc also have config that
ultimately an offload device would want to hook too.
TCP port space
I agree that the issue must get solved and its good that it has
been brought up again. I agree with Chien that the
solution should respect and interface to a single in kernel instance
maintaining host global TCP port space. iWARP is just another
protocol on top of TCP - like iSCSI. There is no
