There is a case where 54xx HBA loads MID firmware as it use 24xx firmware. In this case, the driver should issue MBC_MID_INITIALIZE FIRMWARE even though the HBA doesn't support NPIV. This patch make changes in the driver so that could behave accordingly. Signed-off-by:

Original code would clear the buffer after the firmware had already been initialized to use the buffer, thus potentially and inadvertantly clearing data previously DMA'd by the firmware. Signed-off-by:

FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

As the driver depends on the DPC routine to handle bottom-half loop resynchronization in order to recover from the issue-lip request. The issue_lip call is sleeping context capable, so just issue the reset function there. Signed-off-by:

The driver stores the contents of PCI resources into unsigned long's before ioremapping. This breaks on 32-bit platforms which support 64-bit MMIO resources. Correct code by removing the temporary variables used during MMIO PIO mapping and using resource_size_t where applicable. Also correct a small typo in a printk() where the wrong region number was displayed. Signed-off-by:

I was amazed at how much embedded space was present in the aacraid driver source files. Just selected five files from the set to clean up for now and the attached patch swelled to 73K in size! - Removed trailing space or tabs - Removed spaces embedded within tabs - Replaced leading 8 spaces with tabs - Removed spaces before ) - Removed ClusterCommand as it was unused (noticed it as one triggered by above) - Replaced scsi_status comparison with 0x02, to compare against SAM_STATUS_CHECK_CONDITION. - Replaced a long series of spaces with tabs - Replaced some simple if...defined() with ifdef/ifndef Signed-off-by:

As of now, compat_ioctl already runs without the BKL, whereas ioctl runs with the BKL. This patch first converts changer_fops to use a .unlocked_ioctl member. It applies the same locking rationale than ch_ioctl_compat() uses to ch_ioctl(). Signed-off-by:

Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them. Signed-off-by:

LLDs don't need to zero out scsi_cmnd::sense_buffer in queuecommand since scsi-ml does. This is a preparation of the future changes to allocate the sense_buffer only when necessary. Many LLDs zero out the sense_buffer before touching it on the error case. This patch lets them alone for now because new APIs for them would be added later on. Signed-off-by:

Due to an internal limit associated with the AdapterTypeText field, SMC required a product ID that overloaded the combined vendor and product ID. A decision was made to ship the SMC products without a vendor string dropping the defacto space that used to delineate vendor and product to boot. To correct this, we needed to adjust the code in the driver to parse out the vendor and product strings for the adapter. We match of 'AOC' in the AdapterTypeText, if so we set the vendor to SMC and place the entire AdapterTypeText into the product field. This only affects the cosmetic presentation of the Adapter vendor and product in the logs and in sysfs. Signed-off-by:

Added support to respond to enclosure service events (controller AIFs) to add, online or offline physical targets reported to sg. Also added online and offlining of arrays. Removed an automatic variable definition in a sub block that hid an earlier definition, determined to be inert as the sub-block use did not interfere. Bumped the driver versioning to stamp the addition of this feature. Signed-off-by:

This patch fixes two bugs pointed by James Bottomley: 1. the if (!sym_data->io_reset). That variable is only ever filled by a stack based completion. If we find it non empty it means this code has been entered twice and we have a severe problem, so that should just become a BUG_ON(sym_data->io_reset). 2. sym_data->io_reset should be set to NULL before the routine is exited otherwise the PCI recovery code could end up completing what will be a bogus pointer into the stack. Big thanks to James Bottomley for help with the patch. Signed-off-by:Krzysztof Helt <krzysztof.h1@w.pl> Signed-off-by:

This is a patch written by Tomohiro Kusumi and submitted to linux-scsi: http://marc.info/?l=linux-scsi&m=118673720712152&w=2 The original patch comment: This patch makes Emulex lpfc driver legacy I/O port free. It has already been acked quite long time ago. So I resubmit the patch. http://lkml.org/lkml/2006/11/22/28 Current lpfc driver is already using pci_select_bars() and pci_enable_device_bars() when the PCI bus has been reset. So I think this patch should also be acked. Signed-off-by:
