b3a7ea8d50 [SCSI] libiscsi: do not block session during logout
There is not need to block the session during logout. Since
we are going to fail the commands that were blocked just fail them
immediately instead.

ec2a1344ad IB/iser: Remove unnecessary includes
<asm/scatterlist.h> is not needed because everyplace it appears,
<linux/scatterlist.h> also appears.  <asm/io.h> is not needed because
nothing seems to be using device IO anyway.

3104a2175d IB/iser: Handle aborting a command after it is sent
The SCSI midlayer may abort a command that was already sent.  If the
initiator is still trying to send the command (or data-out PDUs for
that command), the QP may time out after the midlayer times
out. Therefore, when aborting the command, iSER may still have
references for the command's buffers.  When sending these PDUs, the
sends will complete with an error and their resources will be released
then.

bf32ed33e9 [SCSI] iscsi: rename DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH
This patch renames DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH to avoid
confusion with the drivers default values (DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH
is the iscsi RFC specific default).

f0938401f2 IB/iser: Return error code when PDUs may not be sent
iSER limits the number of outstanding PDUs to send. When this threshold
is reached, it should return an error code (-ENOBUFS) instead of setting
the suspend_tx bit (which should be used only by libiscsi).

initiator.  These cleanups came from David Binderman's list of "set

74a2078061 IB/iser: DMA unmap unaligned for RDMA data before touching it
iSER uses the DMA mapping api to map the page holding the
SCSI command data to the HCA DMA address space. When the
command data is not aligned for RDMA, the data is copied
to/from an allocated buffer which in turn is used for
executing this command. The pages associated with the
command must be unmapped before being touched.

87e8df7a27 IB/iser: Have iSER data transaction object point to iSER conn
iSER uses a data transaction object (struct iser_dto) as part
of its IB data descriptors (struct iser_desc) management.
It also uses a hierarchy of connection structures pointing to
each other. A DTO may exist even after the iscsi_iser connection
pointed by it is destroyed (eg one that is bound to a post
receive buffer which was flushed by the IB HW). Hence DTOs need
point to the lowest connection, which is struct iser_conn.

e85b24b5e7 IB/iser: iSER initiator iSCSI PDU and TX/RX
This file contains the iSER initiator processing of iSCSI PDUs - controls,
commands and data-outs along with processing of TX and RX completions.
It interacts with the lower level iser code doing the memory registration
and and the cma and verbs calls.
