bfa: Fix undefined bit shift on big-endian architectures with 32-bit DMA address

2014-09-13T22:41:39+00:00

commit 03a6c3ff3282ee9fa893089304d951e0be93a144 upstream.

bfa_swap_words() shifts its argument (assumed to be 64-bit) by 32 bits
each way.  In two places the argument type is dma_addr_t, which may be
32-bit, in which case the effect of the bit shift is undefined:

drivers/scsi/bfa/bfa_fcpim.c: In function 'bfa_ioim_send_ioreq':
drivers/scsi/bfa/bfa_fcpim.c:2497:4: warning: left shift count >= width of type [enabled by default]
    addr = bfa_sgaddr_le(sg_dma_address(sg));
    ^
drivers/scsi/bfa/bfa_fcpim.c:2497:4: warning: right shift count >= width of type [enabled by default]
drivers/scsi/bfa/bfa_fcpim.c:2509:4: warning: left shift count >= width of type [enabled by default]
    addr = bfa_sgaddr_le(sg_dma_address(sg));
    ^
drivers/scsi/bfa/bfa_fcpim.c:2509:4: warning: right shift count >= width of type [enabled by default]

Avoid this by adding casts to u64 in bfa_swap_words().

Compile-tested only.

bfa: Chinook quad port 16G FC HBA claim issue

2014-04-01T23:58:39+00:00

commit dcaf9aed995c2b2a49fb86bbbcfa2f92c797ab5d upstream.

Bfa driver crash is observed while pushing the firmware on to chinook
quad port card due to uninitialized bfi_image_ct2 access which gets
initialized only for CT2 ASIC based cards after request_firmware().
For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting
initialized as there is no check for chinook PCI device ID before
request_firmware and instead bfi_image_cb is initialized as it is the
default case for card type check.

This patch includes changes to read the right firmware for quad port chinook.

scsi: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:31:23+00:00

For the basic SCSI infrastructure files that are exporting symbols
but not modules themselves, add in the basic export.h header file
to allow the exports.

Fast-forward merge with Linus to be able to merge patches
based on more recent version of the tree.

Remove unneeded version.h includes from drivers/scsi/

2011-09-15T12:57:07+00:00

It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in drivers/scsi/.
This patch removes them.

[SCSI] bfa: Introduced initiator based lun masking feature.

2011-07-27T10:55:03+00:00

- Added support to enable initiator based lun masking.
- Initiator based Lun masking works similar to zoning where
  initiator port is allowed to see only those LUNs which are
  configured to be seen.

[SCSI] bfa: Add support to store driver configuration in flash.

2011-07-27T10:54:03+00:00

- Added dconf (Driver Config) BFA sub-module.
- The dconf sub-module provides interfaces and manages flash writes
  to the flash DRV parition.
- dconf sub-module also ensures that the whole 64K DRV partition is updated
  on a flash write.
