SBC3r26 contains many changes to the Logical Block Provisioning interfaces (formerly known as Thin Provisioning ditto). This patch implements support for both the old and new schemes using the same heuristic as before (whether the LBP VPD page is present). The new code also allows the provisioning mode (i.e. choice of command) to be overridden on a per-device basis via sysfs. Two additional modes are supported in this version: - WRITE SAME(10) with the UNMAP bit set - WRITE SAME(10) without the UNMAP bit set. This allows us to support devices that predate the TP/LBP enhancements in SBC3 and which work by way zero-detection Switching between modes has been consolidated in a helper function that also updates the block layer topology according to the limitations of the chosen command. I experimented with trying WRITE SAME(16) if UNMAP fails, WRITE SAME(10) if WRITE SAME(16) fails, etc. but found several devices that got cranky. So for now we'll disable discard if one of the commands fail. The user still has the option of selecting a different mode in sysfs. Signed-off-by:

When debugging DIF/DIX it is very helpful to be able to see which DIX operation is associated with the scsi_cmnd. Include the protection op in the SCSI command trace. Signed-off-by:

the target infrastructure fails to send the correct conventional size to READ_CAPACITY that force a retry with READ_CAPACITY_16, which reads the capacity for devices > 2TB. Fix by adding the correct return to trigger RC(16). Reported-by:

This driver is for Broadcom Netxtreme II 57712 chip. The following patch contains the driver sources for bnx2fc driver. libfc/libfcoe changes to enable bnx2fc have already gone through the fcoe tree. bnx2fc is a SCSI low level driver that interfaces with SCSI midlayer, libfc, libfcoe, cnic modules. bnx2fc driver uses services of libfc for slow path operations such as FIP and fabric discovery. The fast path IO perations are performed after offloading the session information to the underlying FCoE firmware. Signed-off-by:

Reset using "fcoeadm -r" also needs to restart FIP before doing libfc lport reset, this is needed for new switch firmware requiring FIP solicitation before doing FLOGI again during reset. So this patch does this by doing fcoe_ctlr_link_down and then fcoe_ctlr_link_up to reset the interface. The fcoe_ctlr_link_down call path also does lport reset and then fcoe_ctlr_link_up re-starts the fabric login after doing FIP solicitation first to get reset feature working again. Signed-off-by:

When L2 driver is unloaded, libfcoe_destroy tries to access the fcoe transport structure matching the netdev. However, since the netdev is unregistered by that time, it fails to do so. Hence the stale mappings exists in the fcoe-netdev list. Handle NETDEV_UREGISTER device notification mechanism to remove the stale fcoe-netdev mapping. Signed-off-by:

EM anchors list initialization for only master port was not enough to keep npiv working as described here:- https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html So this patch moves fc_exch_mgr_list_clone to update npiv ports EMs once EM anchors list initialized. Also some cleanup, no need to set lport = NULL as that always get initialized later. Signed-off-by:

When abort for an exchange timed out it didn't release the reference to the exchange resulting in a memory leak. After discussion with the author of the patch (CC) that introduced this bug it was suggested to revert that patch. This reverts commit ea3e2e72.

When an fcoe interface is being destroyed; in the process the fcoe driver will try to release all the resources it had allocated for that interface including rports. But, it seems that it does not release the reference held for the name server rport in that process resulting into a memory leak. This patch fixes that memory leak. Signed-off-by:

If the port takes a while to transition we could exhaust the retries when using DID_TRANSPORT_DISRUPTED. For this case we do not want to use any of the cmd's retries, because if the command was running then when it got failed the retry counter was already incremented. And if this is the first time we are seeing the command, (it got queued because it slipped through during the race) then it should not have its retries incremented. The fc class will decide the correct handling later. Signed-off-by:

We'll be using the new version number scheme from now on. The 'k' in the version in the past will be removed. The format will be: <major>.<minor>.<sub_minor>.<iter> A scsi-misc submission increments <sub_minor> and resets <iter>. An scsi-rc-fixes submission, increments <iter>. Signed-off-by:

The fc_block_scsi_eh() might return with status FAST_IO_FAIL indicating I/O has been terminated due to fast_io_fail timeout. In this case the rport is still blocked, so any error recovery will be failing on this port. Hence we need to check if the return value from fc_block_scsi_eh() is something other than 0, in which case it should just return with that status. Signed-off-by:
