IB/iser: Fix device removal flow

2013-06-05T00:03:11+00:00

Change the code to destroy the "last opened" rdma_cm id after making
sure we released all other objects (QP, CQs, PD, etc) associated with
the IB device.

Since iser accesses the IB device using the rdma_cm id, we need to
free any objects that are related to the device that is associated
with the rdma_cm id prior to destroying that id.  When this isn't
done, the low level driver that created this device can be unloaded
before iser has a chance to free all the objects and a such a call may
invoke code segment which isn't valid any more and crash.

ib_srpt: Call target_sess_cmd_list_set_waiting during shutdown_session

2013-05-30T04:30:46+00:00

Given that srpt_release_channel_work() calls target_wait_for_sess_cmds()
to allow outstanding se_cmd_t->cmd_kref a change to complete, the call
to perform target_sess_cmd_list_set_waiting() needs to happen in
srpt_shutdown_session()

Also, this patch adds an explicit call to srpt_shutdown_session() within
srpt_drain_channel() so that target_sess_cmd_list_set_waiting() will be
called in the cases where TFO->shutdown_session() is not triggered
directly by TCM.

Drop unused transport_wait_for_tasks() check in target_wait_for_sess_cmds
shutdown code, and convert tcm_qla2xxx + ib_srpt fabric drivers.

drivers/infiniband/hw: rename random32() to prandom_u32()

2013-05-08T01:38:27+00:00

Use preferable function name which implies using a pseudo-random number
generator.

IB/iser: Add support for iser CM REQ additional info

2013-05-02T00:34:14+00:00

Annex A12 of the IBTA spec defines additional information that needs
to be provided through the CM exchange relating to usage of ZBVA (Zero
Based VAs) and Send With Invalidate over an iSER connection.

Currently, the initiator sets both to not supported, but does provide
the header so that existing iSER targets can be patched to start
looking on the private data carried by the CM.

This is a preparation step to enable iSER with HW drivers for which
FMRs are not supported, such as mlx4 VF instances or new HW devices
which might support only FRWR (Fast Registration Work-Requests) along
the details of the IB_DEVICE_MEM_MGT_EXTENSIONS device capability.

IB/iser: Return error to upper layers on EAGAIN registration failures

2013-05-02T00:34:13+00:00

Commit 819a087316a6 ("IB/iser: Avoid error prints on EAGAIN
registration failures") not only eliminated the error print on that
case, but rather also modified the code such that it doesn't return
any error to upper layers.  As a result a wrong mapping was used.  Fix
this to correctly return the error in that case.

Introduce iser_info() and move informational messages that were
printed as errors to use that macro. Also, cleanup printk leftovers to
use the existing macros.
