From a53eb5e060c0ec7245c8f93b9dcd94afa6041e06 Mon Sep 17 00:00:00 2001 From: James Smart Date: Fri, 27 Apr 2007 12:41:09 -0400 Subject: [SCSI] FC Transport support for vports based on NPIV This patch provides support for FC virtual ports based on NPIV. For information on the interfaces and design, please read the Documentation/scsi/scsi_fc_transport.txt file enclosed within the patch. The RFC was originally posted here: http://marc.info/?l=linux-scsi&m=117226959918393&w=2 Changes from the initial RFC: - Bug fix: needed a transport_class_unregister() for the vport class - Create a symlink to the vport in the shost device if it is not the parent of the vport. - Made symbolic name writable so it can be set after creation - Made the temporary fc_vport_identifiers struct private to the transport. - Deleted the vport_id field from the vport. I couldn't find any good use for it (and symname is a good replacement). - Made the vport_state and vport_last_state "private" attributes. Added the fc_vport_set_state() helper function to manage state transitions - Updated vport_create() to allow a vport to be created in a disabled state. - Added INITIALIZING and FAILED vport states - Added VPCERR_xxx defines for errors to be returned from vport_create() - Created a Documentation/scsi/scsi_fc_transport.txt file that describes the interfaces and expected LLDD behaviors.

Using the N_Port Id + Virtualization (NPIV) mechanism, a point-to-point connection to a Fabric + can be assigned more than 1 N_Port_ID. Each N_Port_ID appears as a + separate port to other endpoints on the fabric, even though it shares one + physical link to the switch for communication. Each N_Port_ID can have a + unique view of the fabric based on fabric zoning and array lun-masking + (just like a normal non-NPIV adapter). Using the Virtual Fabric (VF) + mechanism, adding a fabric header to each frame allows the port to + interact with the Fabric Port to join multiple fabrics. The port will + obtain an N_Port_ID on each fabric it joins. Each fabric will have its + own unique view of endpoints and configuration parameters. NPIV may be + used together with VF so that the port can obtain multiple N_Port_IDs + on each virtual fabric. + + The FC transport is now recognizing a new object - a vport. A vport is + an entity that has a world-wide unique World Wide Port Name (wwpn) and + World Wide Node Name (wwnn). The transport also allows for the FC4's to + be specified for the vport, with FCP_Initiator being the primary role + expected. Once instantiated by one of the above methods, it will have a + distinct N_Port_ID and view of fabric endpoints and storage entities. + The fc_host associated with the physical adapter will export the ability + to create vports. The transport will create the vport object within the + Linux device tree, and instruct the fc_host's driver to instantiate the + virtual port. Typically, the driver will create a new scsi_host instance + on the vport, resulting in a unique namespace for the vport. + Thus, whether a FC port is based on a physical port or on a virtual port, + each will appear as a unique scsi_host with its own target and lun space. + + Note: At this time, the transport is written to create only NPIV-based + vports. However, consideration was given to VF-based vports and it + should be a minor change to add support if needed. The remaining + discussion will concentrate on NPIV. + + Note: World Wide Name assignment (and uniqueness guarantees) are left + up to an administrative entity controling the vport. For example, + if vports are to be associated with virtual machines, a XEN mgmt + utility would be responsible for creating wwpn/wwnn's for the vport, + using it's own naming authority and OUI. (Note: it already does this + for virtual MAC addresses). + + +Device Trees and Vport Objects: +------------------------------- + + Today, the device tree typically contains the scsi_host object, + with rports and scsi target objects underneath it. Currently the FC + transport creates the vport object and places it under the scsi_host + object corresponding to the physical adapter. The LLDD will allocate + a new scsi_host for the vport and link it's object under the vport. + The remainder of the tree under the vports scsi_host is the same + as the non-NPIV case. The transport is written currently to easily + allow the parent of the vport to be something other than the scsi_host. + This could be used in the future to link the object onto a vm-specific + device tree. If the vport's parent is not the physical port's scsi_host, + a symbolic link to the vport object will be placed in the physical + port's scsi_host. + + Here's what to expect in the device tree : + The typical Physical Port's Scsi_Host: + /sys/devices/.../host17/ + and it has the typical decendent tree: + /sys/devices/.../host17/rport-17:0-0/target17:0:0/17:0:0:0: + and then the vport is created on the Physical Port: + /sys/devices/.../host17/vport-17:0-0 + and the vport's Scsi_Host is then created: + /sys/devices/.../host17/vport-17:0-0/host18 + and then the rest of the tree progresses, such as: + /sys/devices/.../host17/vport-17:0-0/host18/rport-18:0-0/target18:0:0/18:0:0:0: + + Here's what to expect in the sysfs tree : + scsi_hosts: + /sys/class/scsi_host/host17 physical port's scsi_host + /sys/class/scsi_host/host18 vport's scsi_host + fc_hosts: + /sys/class/fc_host/host17 physical port's fc_host + /sys/class/fc_host/host18 vport's fc_host + fc_vports: + /sys/class/fc_vports/vport-17:0-0 the vport's fc_vport + fc_rports: + /sys/class/fc_remote_ports/rport-17:0-0 rport on the physical port + /sys/class/fc_remote_ports/rport-18:0-0 rport on the vport + + +Vport Attributes: +------------------------------- + + The new fc_vport class object has the following attributes + + node_name: Read_Only + The WWNN of the vport + + port_name: Read_Only + The WWPN of the vport + + roles: Read_Only + Indicates the FC4 roles enabled on the vport. + + symbolic_name: Read_Write + A string, appended to the driver's symbolic port name string, which + is registered with the switch to identify the vport. For example, + a hypervisor could set this string to "Xen Domain 2 VM 5 Vport 2", + and this set of identifiers can be seen on switch management screens + to identify the port. + + vport_delete: Write_Only + When written with a "1", will tear down the vport. + + vport_disable: Write_Only + When written with a "1", will transition the vport to a disabled. + state. The vport will still be instantiated with the Linux kernel, + but it will not be active on the FC link. + When written with a "0", will enable the vport. + + vport_last_state: Read_Only + Indicates the previous state of the vport. See the section below on + "Vport States". + + vport_state: Read_Only + Indicates the state of the vport. See the section below on + "Vport States". + + vport_type: Read_Only + Reflects the FC mechanism used to create the virtual port. + Only NPIV is supported currently. + + + For the fc_host class object, the following attributes are added for vports: + + max_npiv_vports: Read_Only + Indicates the maximum number of NPIV-based vports that the + driver/adapter can support on the fc_host. + + npiv_vports_inuse: Read_Only + Indicates how many NPIV-based vports have been instantiated on the + fc_host. + + vport_create: Write_Only + A "simple" create interface to instantiate a vport on an fc_host. + A ":" string is written to the attribute. The transport + then instantiates the vport object and calls the LLDD to create the + vport with the role of FCP_Initiator. Each WWN is specified as 16 + hex characters and may *not* contain any prefixes (e.g. 0x, x, etc). + + vport_delete: Write_Only + A "simple" delete interface to teardown a vport. A ":" + string is written to the attribute. The transport will locate the + vport on the fc_host with the same WWNs and tear it down. Each WWN + is specified as 16 hex characters and may *not* contain any prefixes + (e.g. 0x, x, etc). + + +Vport States: +------------------------------- + + Vport instantiation consists of two parts: + - Creation with the kernel and LLDD. This means all transport and + driver data structures are built up, and device objects created. + This is equivalent to a driver "attach" on an adapter, which is + independent of the adapter's link state. + - Instantiation of the vport on the FC link via ELS traffic, etc. + This is equivalent to a "link up" and successfull link initialization. + Futher information can be found in the interfaces section below for + Vport Creation. + + Once a vport has been instantiated with the kernel/LLDD, a vport state + can be reported via the sysfs attribute. The following states exist: + + FC_VPORT_UNKNOWN - Unknown + An temporary state, typically set only while the vport is being + instantiated with the kernel and LLDD. + + FC_VPORT_ACTIVE - Active + The vport has been successfully been created on the FC link. + It is fully functional. + + FC_VPORT_DISABLED - Disabled + The vport instantiated, but "disabled". The vport is not instantiated + on the FC link. This is equivalent to a physical port with the + link "down". + + FC_VPORT_LINKDOWN - Linkdown + The vport is not operational as the physical link is not operational. + + FC_VPORT_INITIALIZING - Initializing + The vport is in the process of instantiating on the FC link. + The LLDD will set this state just prior to starting the ELS traffic + to create the vport. This state will persist until the vport is + successfully created (state becomes FC_VPORT_ACTIVE) or it fails + (state is one of the values below). As this state is transitory, + it will not be preserved in the "vport_last_state". + + FC_VPORT_NO_FABRIC_SUPP - No Fabric Support + The vport is not operational. One of the following conditions were + encountered: + - The FC topology is not Point-to-Point + - The FC port is not connected to an F_Port + - The F_Port has indicated that NPIV is not supported. + + FC_VPORT_NO_FABRIC_RSCS - No Fabric Resources + The vport is not operational.

The presense of this function will + cause the creation of the new attributes on the fc_host. As part of + the physical port completing its initialization relative to the + transport, it should set the max_npiv_vports attribute to indicate the + maximum number of vports the driver and/or adapter supports. + + +Vport Creation: + + The LLDD vport_create() syntax is: + + int vport_create(struct fc_vport *vport, bool disable) + + where: + vport: Is the newly allocated vport object + disable: If "true", the vport is to be created in a disabled stated. + If "false", the vport is to be enabled upon creation. + + When a request is made to create a new vport (via sgio/netlink, or the + vport_create fc_host attribute), the transport will validate that the LLDD + can support another vport (e.g. max_npiv_vports > npiv_vports_inuse). + If not, the create request will be failed. If space remains, the transport + will increment the vport count, create the vport object, and then call the + LLDD's vport_create() function with the newly allocated vport object. + + As mentioned above, vport creation is divided into two parts: + - Creation with the kernel and LLDD. This means all transport and + driver data structures are built up, and device objects created. + This is equivalent to a driver "attach" on an adapter, which is + independent of the adapter's link state. + - Instantiation of the vport on the FC link via ELS traffic, etc. + This is equivalent to a "link up" and successfull link initialization. + + The LLDD's vport_create() function will not synchronously wait for both + parts to be fully completed before returning. It must validate that the + infrastructure exists to support NPIV, and complete the first part of + vport creation (data structure build up) before returning. We do not + hinge vport_create() on the link-side operation mainly because: + - The link may be down. It is not a failure if it is. It simply + means the vport is in an inoperable state until the link comes up. + This is consistent with the link bouncing post vport creation. + - The vport may be created in a disabled state. + - This is consistent with a model where: the vport equates to a + FC adapter. The vport_create is synonymous with driver attachment + to the adapter, which is independent of link state. + + Note: special error codes have been defined to delineate infrastructure + failure cases for quicker resolution. + + The expected behavior for the LLDD's vport_create() function is: + - Validate Infrastructure: + - If the driver or adapter cannot support another vport, whether + due to improper firmware, (a lie about) max_npiv, or a lack of + some other resource - return VPCERR_UNSUPPORTED. + - If the driver validates the WWN's against those already active on + the adapter and detects an overlap - return VPCERR_BAD_WWN. + - If the driver detects the topology is loop, non-fabric, or the + FLOGI did not support NPIV - return VPCERR_NO_FABRIC_SUPP. + - Allocate data structures. If errors are encountered, such as out + of memory conditions, return the respective negative Exxx error code. + - If the role is FCP Initiator, the LLDD is to : + - Call scsi_host_alloc() to allocate a scsi_host for the vport. + - Call scsi_add_host(new_shost, &vport->dev) to start the scsi_host + and bind it as a child of the vport device. + - Initializes the fc_host attribute values. + - Kick of further vport state transitions based on the disable flag and + link state - and return success (zero). + + LLDD Implementers Notes: + - It is suggested that there be a different fc_function_templates for + the physical port and the virtual port. The physical port's template + would have the vport_create, vport_delete, and vport_disable functions, + while the vports would not. + - It is suggested that there be different scsi_host_templates + for the physical port and virtual port. Likely, there are driver + attributes, embedded into the scsi_host_template, that are applicable + for the physical port only (link speed, topology setting, etc). This + ensures that the attributes are applicable to the respective scsi_host. + + +Vport Disable/Enable: + + The LLDD vport_disable() syntax is: + + int vport_disable(struct fc_vport *vport, bool disable) + + where: + vport: Is vport to to be enabled or disabled + disable: If "true", the vport is to be disabled. + If "false", the vport is to be enabled. + + When a request is made to change the disabled state on a vport, the + transport will validate the request against the existing vport state. + If the request is to disable and the vport is already disabled, the + request will fail. Similarly, if the request is to enable, and the + vport is not in a disabled state, the request will fail. If the request + is valid for the vport state, the transport will call the LLDD to + change the vport's state. + + Within the LLDD, if a vport is disabled, it remains instantiated with + the kernel and LLDD, but it is not active or visible on the FC link in + any way. (see Vport Creation and the 2 part instantiation discussion). + The vport will remain in this state until it is deleted or re-enabled. + When enabling a vport, the LLDD reinstantiates the vport on the FC + link - essentially restarting the LLDD statemachine (see Vport States + above). + + +Vport Deletion: + + The LLDD vport_delete() syntax is: + + int vport_delete(struct fc_vport *vport) + + where: + vport: Is vport to delete + + When a request is made to delete a vport (via sgio/netlink, or via the + fc_host or fc_vport vport_delete attributes), the transport will call + the LLDD to terminate the vport on the FC link, and teardown all other + datastructures and references. If the LLDD completes successfully, + the transport will teardown the vport objects and complete the vport + removal. If the LLDD delete request fails, the vport object will remain, + but will be in an indeterminate state. + + Within the LLDD, the normal code paths for a scsi_host teardown should + be followed. E.g. If the vport has a FCP Initiator role, the LLDD + will call fc_remove_host() for the vports scsi_host, followed by + scsi_remove_host() and scsi_host_put() for the vports scsi_host. + + +Other: + fc_host port_type attribute: + There is a new fc_host port_type value - FC_PORTTYPE_NPIV. This value + must be set on all vport-based fc_hosts. Normally, on a physical port, + the port_type attribute would be set to NPORT, NLPORT, etc based on the + topology type and existence of the fabric. As this is not applicable to + a vport, it makes more sense to report the FC mechanism used to create + the vport. + + Driver unload: + FC drivers are required to call fc_remove_host() prior to calling + scsi_remove_host(). This allows the fc_host to tear down all remote + ports prior the scsi_host being torn down. The fc_remove_host() call + was updated to remove all vports for the fc_host as well. + + +Credits +======= +The following people have contributed to this document: + + + + + + +James Smart +james.smart@emulex.com + diff --git a/drivers/scsi/scsi_transport_fc.c b/drivers/scsi/scsi_transport_fc.c index b4d1ece..2176514 100644 --- a/drivers/scsi/scsi_transport_fc.c +++ b/drivers/scsi/scsi_transport_fc.c @@ -19,7 +19,7 @@ * * ======== * - * Copyright (C) 2004-2005 James Smart, Emulex Corporation + * Copyright (C) 2004-2007 James Smart, Emulex Corporation * Rewrite for host, target, device, and remote port attributes, * statistics, and service functions... * @@ -39,6 +39,33 @@ static int fc_queue_work(struct Scsi_Host *, struct work_struct *); /* + * This is a temporary carrier for creating a vport.

The Firmware that supports the new communication commands supports the ability to force a write around of the adapter cache on a command by command basis. In the attached patch we enable mode page 8 and 3f and spoof the results as needed in order to *convince* the layers above to submit writes with the FUA (Force Unit Attention) bit set if the file system or application requires it, if the Firmware supports the write through, or instead to submit a SYNCHRONIZE_CACHE if the Firmware does not. The added value here is for file systems that benefit from this functionality and for clustering or redundancy scenarios. Caveats: By convince, we are responding with a minimal short 3 byte content mode page 8, with only the data the SCSI layer needs and that we can fill confidently. Applications that require the customarily larger mode page 8 results may be confused by this(?). The FUA, or the SYNCHRONIZE_CACHE only affect the cache on the controller. Our firmware by default ensure that the underlying physical drives of the array have their cache turned off so normally this is not a problem. This attached patch is against current scsi-misc-2.6 and was unit tested on RHEL5. Since this is a feature enhancement, it should not be considered for any current stabilization efforts.

In testing it works as well as the previous code did (that is -quite badly-) but we can now read it and as it settles in actually debug the long standing problems it shares with the old driver.

In qla4xxx_build_ddb_list() firmware ddb state needs to be updated by calling qla4xxx_get_ddb_entry(). Fix qla4x00_pci_config() and clean up code.

Keep track of how many - * times this has happened within a single SCSI command; if it - * gets excessive, then FATAL(). - * - * 3. Parity checking is currently disabled, and a few things should - * happen here now that we support synchronous SCSI transfers : - * 1. On soft-reset, we shoould set the EPC (Enable Parity Checking) - * and AAP (Assert SATN/ on parity error) bits in SCNTL0. - * - * 2. We should enable the parity interrupt in the SIEN0 register. - * - * 3. intr_phase_mismatch() needs to believe that message out is - * always an "acceptable" phase to have a mismatch in. If - * the old phase was MSG_IN, we should send a MESSAGE PARITY - * error. If the old phase was something else, we should send - * a INITIATOR_DETECTED_ERROR message. Note that this could - * cause a RESTORE POINTERS message; so we should handle that - * correctly first. Instead, we should probably do an - * initiator_abort. - * - * 4. MPEE bit of CTEST4 should be set so we get interrupted if - * we detect an error. - * - * - * 5. The initial code has been tested on the NCR53c810.

This patch introduces a helper that does the cast called shost_priv. It's similar in spirit to netdev_priv for network drivers. This is the first patch introducing the macro, and the second patch in the series will convert esp and it's subdrivers as an example. Further conversion will wait until the helper is in the tree to make patch juggling easier.

The target will then fail the connection/session. This patch fixes the problem by delaying the cmdsn allocation until we are about to send the pdu. This also removes the xmitmutex. We were using the connection xmitmutex during error handling to handle races with mtask and ctask cleanup and completion. For ctasks we now have nice refcounting and for the mtask, if we hit the case where the mtask timesout and it is floating around somewhere in the driver, we end up dropping the session. And to handle session level cleanup, we use the xmit suspend bit along with scsi_flush_queue and the session lock to make sure that the xmit thread is not possibly transmitting a task while we are trying to kill it.

From there we can set it on a per target basis. The patch fully converts iscsi_tcp, but only hooks up ib_iser for cmd_per_lun since it currently has a lots of preallocations based on can_queue.

To be able to allow each stack or driver or port (virtual or physical) to be able to log into the same target portal we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and the target tuple [TARGETNAME, CONN_ADDRESS, CONN_PORT] to id a session. This patch adds the netdev name, which is used by software iscsi when it binds a session to a netdevice using the SO_BINDTODEVICE sock opt. It cannot use HWADDRESS because if someone did vlans then the same netdevice will have the same mac and the initiator,target id will not be unique.

Typical uses include restarting the adapter after it has been flashed. Bumped revision number for the driver and added a feature to periodically check the adapter's health (check_interval), update the adapter's concept of time (update_interval) and block checking/resetting of the adapter (check_reset).

This patch also adds a timer to internally issues commands to prevent client hangs in the case of a misbehaving server. Tested by modifying the VIOS such that it would occasionally drop one or more request in sequence.

Otherwise scsi_scan_target() might oops as the rport might already been removed from the scsi host and the traversal from the rport to the scsi_host in scsi_scan_target() will fail. Also the portstate already told us that communication with the target has failed, so it's quite pointless to try.

I was right - Cleanup, linuxise, demacro - Remove the BSD dual licence on the new work - Switch the if ALPHA to if __LP64__. (struct size is then right elsewhere) and then to CONFIG_64BIT as per Christoph's request - Fix the recursive locking on a reset. This is the only actual real code change (I hope ;)). I'm not clear what the right way to handle the BIOS param stuff is on n on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't make sense elsewhere Still has a couple of odd things - and there seems to be a commonly shared EEPROM handling error several drivers have. Roughly speaking several SCSI drivers go try and read EEPROM It failed.. Write any changes between the default and the data we read Which is great as for some paths we've no idea what was in before, so each boot won't write it all back, won't checksum but will repeat the bug Also it can still sleep for a second with IRQ off, and there is some dubious looking error path locking marked FIXME in case anyone feels inspired to work on it. Not a newly introduced bug, and at least its now marked.

The end result is the volume goes read-only. This problem is due to the fact the firmware mapped target ids saved in per device object is phys_disk_num for hidden raid components, and target_id for the volume. There is a single case when both phys_disk_num and target_id are equal, so enters this issue. We fix this issue by checking the tflags when the device is torned down, insuring the IO being completed is meant for hidden raid component, not the volume. In addition to this fix, there are a couple other cases to address hidden raid components. For instance task_abort and device reset are not supported by mpt fw for hidden raid components, a bus reset would be required or target reset to volume.

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".

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.
