an external module. When applying the SCST kernel patch to the mainstream
kernel tree with debugging and/or tracing enabled however, the resulting code
triggers a compiler error. This is because the symbols DEBUG and TRACING
conflict with symbols with the same named defined in unrelated kernel headers.
The patch below resolves these conflicts by renaming the following preprocessor
symbols:
- DEBUG into CONFIG_SCST_DEBUG.
- DEBUG_DIGEST_FAILURES into CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES.
- DEBUG_OOM into CONFIG_SCST_DEBUG_OOM.
- DEBUG_RETRY into CONFIG_SCST_DEBUG_RETRY.
- DEBUG_SN into CONFIG_SCST_DEBUG_SN.
- DEBUG_TM into CONFIG_SCST_DEBUG_TM.
- EXTRACHECKS into CONFIG_SCST_EXTRACHECKS.
- SCST_HIGHMEM into CONFIG_SCST_HIGHMEM.
- STRICT_SERIALIZING into CONFIG_SCST_STRICT_SERIALIZING.
- TM_DBG_GO_OFFLINE into CONFIG_SCST_TM_DBG_GO_OFFLINE. Mapped 0/1 values
into macro undefined / macro defined.
- TRACING into CONFIG_SCST_TRACING.
- USE_EXPECTED_VALUES into CONFIG_SCST_USE_EXPECTED_VALUES.
- In qla_isp/linux/isp_scst.c, renamed DEBUG into DEBUG_ISP_SCST.
- In qla_isp/..., renamed SCSI_TARGET in SCST_SCSI_TARGET.
- In qla_isp/..., renamed SCSI_TARGET_DEV in SCST_SCSI_TARGET_DEV.
Additionally, all CONFIG_SCSI_TARGET* macro's are renamed into CONFIG_SCST* in
order to avoid confusion between the STGT CONFIG-symbols and the SCST CONFIG-
symbols.
The following additional options are now configurable through Kconfig:
- CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES
- CONFIG_SCST_STRICT_SERIALIZING
- CONFIG_SCST_STRICT_SECURITY
- CONFIG_SCST_ALLOW_PASSTHROUGH_IO_SUBMIT_IN_SIRQ
- CONFIG_SCST_ABORT_CONSIDER_FINISHED_TASKS_AS_NOT_EXISTING
- CONFIG_SCST_USE_EXPECTED_VALUES
- CONFIG_SCST_DEBUG_OOM
- CONFIG_SCST_DEBUG_RETRY
- CONFIG_SCST_DEBUG_SN
- CONFIG_SCST_DEBUG_TM
- CONFIG_SCST_TM_DBG_GO_OFFLINE
The patch below has been verified as follows:
- Verified that the following command does not print any new warning messages:
make -s clean && make -C srpt -s clean && make -s scst iscsi-scst && make -C srpt -s
- Verified as follows that the internal SCST patches still apply cleanly:
for p in *patch; do patch -p0 --dry-run -f -s <$p; done
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.7 kernel, and that the patched kernel tree still
compiles, installs and boots fine, that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load, and that iSCSI communication
still works fine. All SCST kernel configuration options that could be
enabled have been enabled during this test.

I've updated the MPT fusion target driver for LSI SCSI/FC/SAS HBAs. The original SCST MPT driver was based on the 1.00.13 LSI
sample target driver. LSI has since released version 1.00.14 of the sample target driver. I've ported all the changes from .13 to
.14 into the SCST MPT driver for consistency. I've also updated the SCST MPT driver to compile under 2.6.24 and 2.6.25.4. Finally,
I force the SCSI parallel transfer rate to very slow depending on the SCSI HBA firmware revision. Newer versions of SCSI HBA
firmware have a bug where the incorrect amount of data is transferred for non-divisible-by-4 length transfers (like standard 14 byte
REQUEST SENSE). LSI is aware of the problem and I'll update the driver to restore functionality upon a new good SCSI HBA firmware
release.
I still have not confirmed operation with LSI SAS or FC HBAs.
