2007-10-12[SCSI] lpfc: fix potential overflow of hbqs arrayJesper Juhl1-1/+1
The Coverity checker noticed that we may overrun a statically allocated array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find(). The case is this; In 'struct lpfc_hba' we have #define LPFC_MAX_HBQS 4 ... struct lpfc_hba { ... struct hbq_s hbqs[LPFC_MAX_HBQS]; ... }; But then in lpfc_sli_hbqbuf_find() we have this code hbqno = tag >> 16; if (hbqno > LPFC_MAX_HBQS) return NULL; if 'hbqno' ends up as exactely 4, then we won't return, and then this list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) { will cause an overflow of the statically allocated array at index 4, since the valid indices are only 0-3. I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS' into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.

2007-07-11sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributesZhang Rui1-4/+8
Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo1-2/+0
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

2007-06-17[SCSI] lpfc: NPIV: add NPIV support on top of SLI-3James Smart20-1763/+5021
NPIV support is added to the driver. It utilizes the interfaces of the fc transport for the creation and deletion of vports. Within the driver, a new Scsi_Host is created for each NPIV instance, and is paired with a new instance of a FC port. This allows N FC Port elements to share a single Adapter.

This interface changes some of the basic behaviors such as command and response ring element sizes and data structures, as well as a change in buffer posting. Note: the new firmware extensions are found only on our mid-range and enterprise 4Gig adapters - so NPIV support is available only on these newer adapters.

Adapter handling includes submissions of command requests, receiving responses, and managing adapter resources. The FC port includes the discovery engine, login handling, and the mapping of a Scsi_Host on the "port". Although not a large functional change, as it touches core structures and functions, resulting in a large text delta.

2007-04-01[SCSI] lpfc: fix oops when parsing dodgy VPDAnton Blanchard1-1/+1
We have seen two cases where VPD on an emulex card has been incorrect and we end up walking off the end of memory. It looks like someone made an update (increased the length of a string) without increasing the Length field. Then we do: Length -= (3+i); And since Length is unsigned it becomes very large and we loop forever in the encapsulating: while (Length > 0) { If we make Length signed then we fall out of the loop and proceed on. Its important to note we have only seen this in the lab and it may be the only two cases of this in existence, but since the rest of the code has been written to be resilient against bad VPD we may as well fix this too.
