In some test envirenment, there is loopback topology test. We should handle this during discovery. Signed-off-by:

Instead of blocking the entire host when the port's queueing limit is hit, we should only block the port's target. This will allow IO to other ports to execute. 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:

Based on reading of the FCP2/4 specification, the driver cannot expect the storage device to send FCP_RSP information. Instead, the driver should interpret the data which is present in the frame to base decisions on the success or failure of the system. Signed-off-by:

By not clearing the 'login needed' nor 'login outstanding' states for an fcport after a big-hammer (adapter reset), the driver may not properly perform a PLOGI/PRLI sequence (and lose visibility to the rport) during a follow-on SNS scan. Signed-off-by:

The additional increment of dsd_seg was causing the compiler to throw an array out of bounds warning. This patch moves to a direct assignment of cmd_pkt->fcp_data_dseg_len so that the compiler doesn't generate an array out bounds warning. Signed-off-by:

Query the FC symbolic port name for reporting in the fc_host sysfs and enable the symbolic_name attribute in the fc_host sysfs. When running in NPIV mode, extend the symbolic port name with the devno and the hostname. This allows better identification of Linux systems for SAN and storage administrators. Signed-off-by:

The SCSI host and transport templates are the only members left in the global zfcp_data struct. Move them out of zfcp_data and remove the now unused zfcp_data struct. Also update the names of the register and unregister functions to use the zfcp_scsi prefix. Signed-off-by:

For task management commands, only LUN and flags are required. The regular FCP setup already sets the LUN in the fcp_cmnd. All is required for merging the function is setting up the TM flags. Signed-off-by:

Allocate the data for the GID_PN request through the new FC kmem_cache. While updating the GID_PN code, also introduce a helper function for initializing the CT header for FC nameserver requests. Remove the "paranoia" check as well, the GID_PN request data does not suddenly change. Signed-off-by:

A data buffer that is passed to the hardware must not cross a page boundary. zfcp uses a series of kmem_caches to align the data to not cross a page boundary. Introduce a new kmem_cache for the FC requests sent from the zfcp driver and use it for the ELS ADISC data. The goal is to migrate to the FC kmem_cache in later patches and remove the request specific kmem_caches. Signed-off-by:

zfcp requires a mempool for the status read data blocks to resubmit the "status read" requests at any time. Each status read data block has the size of a page (4096 bytes) and needs to be placed in one page. Instead of having a kmem_cache for allocating page sized chunks, use mempool_create_page_pool to create a mempool returning pages and remove the zfcp kmem_cache. Signed-off-by:
