target: Pass in transport supported PI at session initialization

2014-04-07T08:48:54Z

In order to support local WRITE_INSERT + READ_STRIP operations for non PI enabled fabrics, the fabric driver needs to be able signal what protection offload operations are supported. This is done at session initialization time so the modes can be signaled by individual se_wwn + se_portal_group endpoints, as well as optionally across different transports on the same endpoint. For iser-target, set TARGET_PROT_ALL if the underlying ib_device has already signaled PI offload support, and allow this to be exposed via a new iscsit_transport->iscsit_get_sup_prot_ops() callback. For loopback, set TARGET_PROT_ALL to signal SCSI initiator mode operation. For all other drivers, set TARGET_PROT_NORMAL to disable fabric level PI. Cc: Martin K.

target: Add TFO->abort_task for aborted task resources release

2014-04-07T08:48:51Z

Now that TASK_ABORTED status is not generated for all cases by TMR ABORT_TASK + LUN_RESET, a new TFO->abort_task() caller is necessary in order to give fabric drivers a chance to unmap hardware / software resources before the se_cmd descriptor is released via the normal TFO->release_cmd() codepath. This patch adds TFO->aborted_task() in core_tmr_abort_task() in place of the original transport_send_task_abort(), and also updates all fabric drivers to implement this caller. The fabric drivers that include changes to perform cleanup via ->aborted_task() are: - iscsi-target - iser-target - srpt - tcm_qla2xxx The fabric drivers that currently set ->aborted_task() to NOPs are: - loopback - tcm_fc - usb-gadget - sbp-target - vhost-scsi For the latter five, there appears to be no additional cleanup required before invoking TFO->release_cmd() to release the se_cmd descriptor. v2 changes: - Move ->aborted_task() call into transport_cmd_finish_abort (Alex) Cc: Alex Leung Cc: Mark Rustad Cc: Roland Dreier Cc: Vu Pham Cc: Chris Boot Cc: Sebastian Andrzej Siewior Cc: Michael S.

The return value wasn't checked by any of the callers.

Pull SCSI target patches from Nicholas Bellinger: "Here are the remaining target-pending patches for v3.9-rc1. The most important one here is the immediate queue starvation regression fix for iscsi-target, which addresses a bug that's effecting v3.5+ kernels under heavy sustained READ only workloads. Thanks alot to Benjamin Estrabaud for helping to track this down! Also included is a pSCSI exception bugfix from Asias, along with a handful of other minor changes.

2012-12-13T05:17:25Z

If the TPG memory is allocated successfully, but we fail further along in the function, a dangling pointer to freed memory is left in the TPort structure. This is mostly harmless, but does prevent re-trying the operation without first removing the TPort altogether. Reported-by: Chen Gang Signed-off-by: Chris Boot Cc: Andy Grover Cc: Nicholas A.
