Reduce the number of dst_get_neighbour_noref() calls within a single
call chain. Primarily by passing the neighbour pointer down to the
helper functions.Handle dst_get_neighbour_noref() returning NULL in ipoib_start_xmit()
by incrementing the dropped counter and freeing the packet. We don't
want it to fall through into the ARP/RARP/multicast handling, since
that should only happen when skb_dst() is NULL.Signed-off-by: David S. Miller

ib0: ib_address_create failed
The code below in ipoib_mcast_join_finish() will note the above
failure in the address handle but otherwise continue:ah = ipoib_create_ah(dev, priv->pd, &av);
if (!ah) {
ipoib_warn(priv, "ib_address_create failed\n");
} else {The while loop at the bottom of ipoib_mcast_join_finish() will attempt
to send queued multicast packets in mcast->pkt_queue and eventually
end up in ipoib_mcast_send():if (!mcast->ah) {
if (skb_queue_len(&mcast->pkt_queue) < IPOIB_MAX_MCAST_QUEUE)
skb_queue_tail(&mcast->pkt_queue, skb);
else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}My read is that the code will requeue the packet and return to the
ipoib_mcast_join_finish() while loop and the stage is set for the
"hung" task diagnostic as the while loop never sees a non-NULL ah, and
will do nothing to resolve.There are GFP_ATOMIC allocates in the provider routines, so this is
possible and should be dealt with.The test that induced the failure is associated with a host SM on the
same server during a shutdown.This patch causes ipoib_mcast_join_finish() to exit with an error
which will flush the queued mcast packets. Nothing is done to unwind
the QP attached state so that subsequent sends from above will retry
the join.Reviewed-by: Ram Vepa

The driver counted on the transactional nature of iSCSI login/text
flows and used the same buffer for both the request and the response.
We also went further and did DMA mapping only once, with
DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by
using different buffers, one for requests and one for responses, and
use the correct DMA mapping direction for each.Signed-off-by: Or Gerlitz

SCSI scanning of a channel:id:lun triplet in Linux works as follows
(function scsi_scan_target() in drivers/scsi/scsi_scan.c):- If lun == SCAN_WILD_CARD, send a REPORT LUNS command to the target
and process the result.- If lun != SCAN_WILD_CARD, send an INQUIRY command to the LUN
corresponding to the specified channel:id:lun triplet to verify
whether the LUN exists.So a SCSI driver must either take the channel and target id values in
account in its quecommand() function or it should declare that it only
supports one channel and one target id.Currently the ib_srp driver does neither. As a result scanning the
SCSI bus via e.g. rescan-scsi-bus.sh causes many duplicate SCSI
devices to be created. For each 0:0:L device, several duplicates are
created with the same LUN number and with (C:I) != (0:0). Fix this by
declaring that the ib_srp driver only supports one channel and one
target id.Signed-off-by: Bart Van Assche
