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:

Switch the allocation of the GPN_FT request data to the FC kmem_cache and remove the zfcp_gpn kmem_cache. 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:

The ep_disconnect function could be freeing the ep while beiscsi_conn_get_param is running. This has the driver use the get ep param callback instead of the get conn param to fix this. Signed-off-by:

Mike Christie authored
bnx2i has some checks to try and make sure the ep is not destroyed while the addr/port is getting read. However, if after this check: if (!(bnx2i_conn && bnx2i_conn->ep && bnx2i_conn->ep->hba)) goto out; bnx2i_conn->ep is cleared by ep_disconnect then we will oops. This patches fixes the problem by having the driver use the get_ep_param callback instead of get_conn_param. Signed-off-by:

This has cxgbi use the iscsi_conn_get_addr_param helper and the get ep callback. Signed-off-by:

Mike Christie authored
For drivers using the ep callbacks the addr and port are attached to the endpoint instead of the conn. This adds a callout to the iscsi_transport to get ep values. It also adds locking around the get param call to make sure that ep_disconnect does not free the LLD's ep interconnect structs from under us (the ep has a refcount so it will not go away but the LLD may have structs from other subsystems that are not allocated in the ep so we need to protect them from getting freed).

This has iscsi_tcp use the iscsi_conn_get_addr_param libiscsi function. It also drops the use of the libiscsi session portal buffers, so they can be removed in the next patches. Instead of copying the values at bind time we get them during get() time. If we are not connected userspace will now get -ENOTCONN, so it knows that connection is disconnected instead of a possible stale value. Signed-off-by:

The active variable on the iscsi_cls_conn is not used so this patch removes it. Signed-off-by:

Mike Christie authored
When iscsid restarts it does not know the connection's endpoint, so it is getting leaked. This fixes the problem by having the iscsi class force a disconnect before a new connection is bound. Signed-off-by:

For scenarios where the shost is not being passed to bnx2i for the iSCSI offload connection request, the code would consult the routing table to select the CNIC device. This code path will erroneously error out if the corresponding L2 interface's MTU has been setup to > 1500. Signed-off-by:
