Hi all,
this patchset updates the SCSI stack to support full 64-bit LUNs.
The first patch is a simple fix; the next patch updates
the sequential scan logic to be compliant with SPC.
The third patch addresses a firmware issue with earlier
qla2xxx HBAs.
The next two patches update the SCSI stack and all drivers
to use 64-bit LUNs where appropriate.
And finally we need to update the conversion routines
scsilun_to_int to cope with 64bit LUNs.
Two drivers have issues with 64bit LUNs:
- The qla2xxx driver uses a 32-bit LUN value for TMFs.
But as the driver uses a max_lun value from 0xFFFF
we should be safe for the time being.
- The zfcp driver uses a 32-bit LUN for debug records; the
record format would need to be updated to cope with
64-bit LUNs. But again, this driver uses 0xFFFFFFFF
for max_lun, so it doesn't do any harm.
The other changes have been pretty straightforward.
Changes to v3:
- Modified scsilun_to_int() as suggested by James B.
Changes to v2:
- Add patch to fixup scsilun_to_int
- Add Reviewed-by: where applicable
- Remove last references to SCSI_MULTI_LUN
Hannes Reinecke (6):
scsi: Remove CONFIG_SCSI_MULTI_LUN
scsi_scan: Restrict sequential scan to 256 LUNs
qla2xxx: Restrict max_lun to 16-bit for older HBAs
scsi: use 64-bit LUNs
scsi: use 64-bit value for 'max_luns'
scsi_scan: Fixup scsilun_to_int()

SAM revisions later than SCSI-3 impose a structure on LUNs larger than 256, making LUN numbers between 256 and 16384 illegal. SCSI-3, however allows for plain 64-bit numbers with no internal structure. So restrict sequential LUN scan to 256 LUNs and add a new blacklist flag 'BLIST_SCSI3LUN' to scan up to max_lun devices.

In sg_luns, to support translating between the T10 and Linux representation of 64 bit LUNs, there are these two versions: static uint64_t t10_2linux_lun(const unsigned char t10_lun[]) { const unsigned char * cp; uint64_t res; res = (t10_lun[6] << 8) + t10_lun[7]; for (cp = t10_lun + 4; cp >= t10_lun; cp -= 2) { res <<= 16; res += (*cp << 8) + *(cp + 1); } return res; } /* Copy of t10_lun --> Linux unsigned int (i.e. 32 bit ) present in Linux * kernel, up to least lk 3.8.0, extended to 64 bits. * BEWARE: for sizeof(int==4) this function is BROKEN and is left here as * as example and may soon be removed. */ static uint64_t t10_2linux_lun64bitBR(const unsigned char t10_lun[]) { int i; uint64_t lun; lun = 0; for (i = 0; i < (int)sizeof(lun); i += 2) lun = lun | (((t10_lun[i] << 8) | t10_lun[i + 1]) << (i * 8)); return lun; } The second one (with "BR" (for broken) appended) is for testing. And that second one looks very similar to the code you are objecting to. Doug Gilbert ^ permalink raw reply [flat|nested] 24+ messages in thread

For sizeof(int)==4 then unsigned char << 32 unsigned char << 40 <etc> does _not_ give a 64 bit quantity. It is undefined but seems to wrap on a 32 bit unsigned int (i.e. 32 bits).

Hello Hannes, Many SCSI LLD's use int_to_scsilun() in the hot path (queuecommand()). This patch series makes the int_to_scsilun() function slightly more expensive. Has it been considered to cache the result of int_to_scsilun() such that LLD's can copy the cached int_to_scsilun() result instead of having to call int_to_scsilun() in the queuecommand() function ? Something like the (untested) patch below might be sufficient: diff --git a/drivers/scsi/scsi_scan.c b/drivers/scsi/scsi_scan.c index e02b3aa..9e50d78 100644 --- a/drivers/scsi/scsi_scan.c +++ b/drivers/scsi/scsi_scan.c @@ -244,6 +244,7 @@ static struct scsi_device *scsi_alloc_sdev(struct scsi_target *starget, sdev->queue_ramp_up_period = SCSI_DEFAULT_RAMP_UP_PERIOD; sdev->id = starget->id; sdev->lun = lun; + int_to_scsilun(lun, &sdev->scsi_lun); sdev->channel = starget->channel; sdev->sdev_state = SDEV_CREATED; INIT_LIST_HEAD(&sdev->siblings); diff --git a/include/scsi/scsi_device.h b/include/scsi/scsi_device.h index 5853c91..48ea68e 100644 --- a/include/scsi/scsi_device.h +++ b/include/scsi/scsi_device.h @@ -100,6 +100,8 @@ struct scsi_device { unsigned int id, lun, channel; + struct scsi_lun scsi_lun; /* int_to_scsilun(lun) */ + unsigned int manufacturer; /* Manufacturer of device, for using * vendor-specific cmd's */ unsigned sector_size; /* size in bytes */ Thanks, Bart. ^ permalink raw reply related [flat|nested] 24+ messages in thread

That's fine with me. I have one more question about this patch series though: if you mention 64-bit LUNs, are you referring to multi-level LUNs only or also to so-called extended LUNs ? I think the byte reordering done by scsilun_to_int() is fine for multi-level LUNs but unnatural for extended LUNs. As an example, in SAM-5 the format for eight byte extended LUNs is defined as follows (paragraph 4.7.7.5.3): byte 0: address method (3), length (2) and extended address method (2) bytes 1..7: long extended flat space LUN with the MSB in byte 1 and LSB in byte 7. Today scsilun_to_int() does not preserve the MSB..LSB byte order for extended LUNs. I think if we want to preserve the byte order in scsilun_to_int() that that function will have to be made dependent on the LUN addressing method. That would make scsilun_to_int() more complex. Hence the proposal to cache the SCSI LUN such that the queuecommand() functions are not slowed down by a call into int_to_scsilun(). Bart. ^ permalink raw reply [flat|nested] 24+ messages in thread

The only constant with LUNs is that T10 will keep tinkering with them. The original LUNs were 3 bits long embedded in the cdb. Today we have 65 bit LUNs (the 64 you have been looking at and LU_CONG in the INQUIRY response). Decoding LUNs is best avoided if possible. int_to_scsilun() was a hack that made 16 bit LUNs look half reasonable as integers. Beyond 16 bits, it just looks like a random number generator. As long as the "int" that is produced can be mapped to a T10 LUN and vice versa, it doesn't matter. Doug Gilbert ^ permalink raw reply [flat|nested] 24+ messages in thread
* [PATCHv3 0/6] Support 64-bit LUNs @ 2014-05-31 9:01 Hannes Reinecke 2014-05-31 9:01 ` [PATCH 5/6] scsi: use 64-bit value for 'max_luns' Hannes Reinecke 0 siblings, 1 reply; 24+ messages in thread From: Hannes Reinecke @ 2014-05-31 9:01 UTC (permalink / raw) To: James Bottomley Cc: Christoph Hellwig, Ewan Milne, linux-scsi, Hannes Reinecke Hi all, this patchset updates the SCSI stack to support full 64-bit LUNs. The first patch is a simple fix; the next patch updates the sequential scan logic to be compliant with SPC. The third patch addresses a firmware issue with earlier qla2xxx HBAs. The next two patches update the SCSI stack and all drivers to use 64-bit LUNs where appropriate. And finally we need to update the conversion routine scsilun_to_int() to cope with 64bit LUNs. Two drivers have issues with 64bit LUNs: - The qla2xxx driver uses a 32-bit LUN value for TMFs. But as the driver uses a max_lun value from 0xFFFF we should be safe for the time being. - The zfcp driver uses a 32-bit LUN for debug records; the record format would need to be updated to cope with 64-bit LUNs. But again, this driver uses 0xFFFFFFFF for max_lun, so it doesn't do any harm. The other changes have been pretty straightforward. Changed to v2: - Add patch to fixup scsilun_to_int - Add Reviewed-by: where applicable - Remove last references to SCSI_MULTI_LUN Hannes Reinecke (6): scsi: Remove CONFIG_SCSI_MULTI_LUN scsi_scan: Restrict sequential scan to 256 LUNs qla2xxx: Restrict max_lun to 16-bit for older HBAs scsi: use 64-bit LUNs scsi: use 64-bit value for 'max_luns' scsi_scan: Fixup scsilun_to_int() Documentation/scsi/tmscsim.txt | 2 - drivers/ata/libata-scsi.c | 2 +- drivers/ata/libata.h | 2 +- drivers/message/fusion/mptscsih.c | 2 +- drivers/message/i2o/i2o_scsi.c | 11 ++-- drivers/s390/scsi/zfcp_dbf.c | 3 +- drivers/s390/scsi/zfcp_unit.c | 4 +- drivers/scsi/Kconfig | 14 ------ drivers/scsi/NCR5380.c | 2 +- drivers/scsi/aacraid/linit.c | 2 +- drivers/scsi/advansys.c | 2 +- drivers/scsi/aha152x.c | 6 +-- drivers/scsi/aic7xxx/aic79xx.h | 2 +- drivers/scsi/aic7xxx/aic79xx_osm.c | 6 +-- drivers/scsi/aic7xxx/aic79xx_proc.c | 2 +- drivers/scsi/aic7xxx/aic7xxx_osm.c | 11 ++-- drivers/scsi/aic7xxx/aic7xxx_proc.c | 2 +- drivers/scsi/arcmsr/arcmsr_hba.c | 8 +-- drivers/scsi/csiostor/csio_scsi.c | 24 ++++----- drivers/scsi/cxgbi/libcxgbi.c | 2 +- drivers/scsi/cxgbi/libcxgbi.h | 2 +- drivers/scsi/dc395x.c | 51 ++++++++----------- drivers/scsi/eata.c | 4 +- drivers/scsi/fnic/fnic_scsi.c | 4 +- drivers/scsi/hpsa.c | 2 +- drivers/scsi/ibmvscsi/ibmvfc.c | 4 +- drivers/scsi/libiscsi.c | 8 +-- drivers/scsi/libsas/sas_scsi_host.c | 11 ++-- drivers/scsi/lpfc/lpfc_attr.c | 10 +++- drivers/scsi/lpfc/lpfc_scsi.c | 36 ++++++------- drivers/scsi/megaraid.c | 6 +-- drivers/scsi/megaraid/mega_common.h | 2 +- drivers/scsi/mpt3sas/mpt3sas_scsih.c | 4 +- drivers/scsi/ncr53c8xx.h | 4 -- drivers/scsi/pmcraid.c | 2 +- drivers/scsi/qla2xxx/qla_def.h | 6 +-- drivers/scsi/qla2xxx/qla_gbl.h | 18 +++---- drivers/scsi/qla2xxx/qla_iocb.c | 11 ++-- drivers/scsi/qla2xxx/qla_isr.c | 4 +- drivers/scsi/qla2xxx/qla_mbx.c | 12 ++--- drivers/scsi/qla2xxx/qla_mr.c | 8 +-- drivers/scsi/qla2xxx/qla_os.c | 48 ++++++++++-------- drivers/scsi/qla4xxx/ql4_glbl.h | 4 +- drivers/scsi/qla4xxx/ql4_iocb.c | 2 +- drivers/scsi/qla4xxx/ql4_isr.c | 22 ++++---- drivers/scsi/qla4xxx/ql4_mbx.c | 6 +-- drivers/scsi/qla4xxx/ql4_os.c | 20 ++++---- drivers/scsi/scsi.c | 8 +-- drivers/scsi/scsi_debug.c | 15 +++--- drivers/scsi/scsi_priv.h | 2 +- drivers/scsi/scsi_proc.c | 2 +- drivers/scsi/scsi_scan.c | 97 +++++++++++++++--------------------- drivers/scsi/scsi_sysfs.c | 14 +++--- drivers/scsi/scsi_transport_fc.c | 4 +- drivers/scsi/scsi_transport_iscsi.c | 4 +- drivers/scsi/scsi_transport_sas.c | 2 +- drivers/scsi/sg.c | 4 +- drivers/scsi/sym53c8xx_2/sym_glue.c | 2 +- drivers/scsi/sym53c8xx_2/sym_hipd.h | 2 +- drivers/target/loopback/tcm_loop.c | 2 +- drivers/target/target_core_pscsi.c | 12 ++--- drivers/usb/storage/Kconfig | 4 +- drivers/usb/storage/sddr09.c | 4 +- drivers/usb/storage/usb.c | 10 ++-- include/linux/moduleparam.h | 5 ++ include/scsi/scsi.h | 2 +- include/scsi/scsi_device.h | 22 ++++---- include/scsi/scsi_devinfo.h | 2 + include/scsi/scsi_host.h | 6 +-- include/scsi/scsi_transport.h | 2 +- kernel/params.c | 1 + 71 files changed, 314 insertions(+), 334 deletions(-) -- 1.7.12.4 ^ permalink raw reply [flat|nested] 24+ messages in thread
