IB/isert: do not ignore errors in dma_map_single()

2016-12-14T17:51:31+00:00

There are several places, where errors in dma_map_single() are
ignored. The patch fixes them.

Found by Linux Driver Verification project (linuxtesting.org).

IB/isert: Remove and fix debug prints after allocation failure

2016-12-03T18:12:52+00:00

The prints after [k|v][m|z|c]alloc() functions are not needed,
because in case of failure, allocator will print their internal
error prints anyway.

Pull main rdma updates from Doug Ledford:
 "This is the main pull request for the rdma stack this release.  The
  code has been through 0day and I had it tagged for linux-next testing
  for a couple days.

  Summary:

   - updates to mlx5

   - updates to mlx4 (two conflicts, both minor and easily resolved)

   - updates to iw_cxgb4 (one conflict, not so obvious to resolve,
     proper resolution is to keep the code in cxgb4_main.c as it is in
     Linus' tree as attach_uld was refactored and moved into
     cxgb4_uld.c)

   - improvements to uAPI (moved vendor specific API elements to uAPI
     area)

   - add hns-roce driver and hns and hns-roce ACPI reset support

   - conversion of all rdma code away from deprecated
     create_singlethread_workqueue

   - security improvement: remove unsafe ib_get_dma_mr (breaks lustre in
     staging)"

IB/core: add support to create a unsafe global rkey to ib_create_pd

2016-09-23T17:47:44+00:00

Instead of exposing ib_get_dma_mr to ULPs and letting them use it more or
less unchecked, this moves the capability of creating a global rkey into
the RDMA core, where it can be easily audited.  It also prints a warning
everytime this feature is used as well.

IB/isert: Properly release resources on DEVICE_REMOVAL

2016-09-02T17:46:32+00:00

When the low level driver exercises the hot unplug they would call
rdma_cm cma_remove_one which would fire DEVICE_REMOVAL event to all cma
consumers. Now, if consumer doesn't make sure they destroy all IB
objects created on that IB device instance prior to finalizing all
processing of DEVICE_REMOVAL callback, rdma_cm will let the lld to
de-register with IB core and destroy the IB device instance. And if the
consumer calls (say) ib_dereg_mr(), it will crash since that dev object
is NULL.

In the current implementation, iser-target just initiates the cleanup
and returns from DEVICE_REMOVAL callback. This deferred work creates a
race between iser-target cleaning IB objects(say MR) and lld destroying
IB device instance.

This patch includes the following fixes
  -> make sure that consumer frees all IB objects associated with device
     instance
  -> return non-zero from the callback to destroy the rdma_cm id

   - Fix target session shutdown bug for ib_srpt multi-channel (hch)
   - Make TFO close_session() and shutdown_session() optional (hch)
   - Drop se_sess->sess_kref + convert tcm_qla2xxx to internal kref
     (hch)
   - Add tcm_qla2xxx endpoint attribute for basic FC jammer (Laurence)
   - Refactor iscsi-target RX/TX PDU encode/decode into common code
     (Varun)
   - Extend iscsit_transport with xmit_pdu, release_cmd, get_rx_pdu,
     validate_parameters, and get_r2t_ttt for generic ISO offload

   - Initial merge of cxgb iscsi-segment offload target driver (Varun)

  The bulk of the changes are Chelsio's new driver, along with a number
  of iscsi-target common code improvements made by Varun + Co along the
  way"
