scsi: lpfc: Define types in a union for generic void *context3 ptr In LPFC_MBOXQ_t, the void *context3 ptr is used for various paths. It is treated as a generic pointer, and is type casted during its usage. The issue with this is that it can sometimes get confusing when reading code as to what the context3 ptr is being used for and mistakenly be reused in a different context. Rename context3 to ctx_u, and declare it as a union of defined ptr types. From now on, the ctx_u ptr may be used only if users define the use case type.

scsi: lpfc: Define lpfc_dmabuf type for ctx_buf ptr In LPFC_MBOXQ_t, the ctx_buf ptr shouldn't be defined as a generic void *ptr. It is named ctx_buf and it should only be used as an lpfc_dmabuf *ptr. Due to the void* declaration, there have been abuses of ctx_buf for things not related to lpfc_dmabuf. So, set the ptr type for *ctx_buf as lpfc_dmabuf. Remove all type casts on ctx_buf because it is no longer a void *ptr. Convert the abuse of ctx_buf for something not related to lpfc_dmabuf to use the void *context3 ptr. A particular abuse of the ctx_buf warranted a new void *ext_buf ptr. However, the usage of this new void *ext_buf is not generic. It is intended to only hold virtual addresses for extended mailbox commands.

scsi: lpfc: Defer issuing new PLOGI if received RSCN before completing REG_LOGIN When mapped to a target with multiple virtual ports, a link bounce sometimes results in unsuccessful rediscovery of all of the target's virtual ports. This is because a succession of repeat RSCNs for the virtual target ports leaves ndlps in the REG_LOGIN state with the NLP_REG_LOGIN_SEND flag set. With NLP_REG_LOGIN_SEND set, during the next PLOGI, the driver will UNREG_RPI. When UNREG_RPI is processed, the driver can be in the middle of PRLI_ISSUE or MAPPED state resulting in an illegal state transition by the discovery engine and stalling. Fix by calling the discovery state machine with DEVICE_RECOVERY event during RSCN processing. This will set the NLP_IGNR_REG_CMPL bit and prevent the old REG_LOGIN state from advancing. Then for the new PLOGI issue, add the check for the NLP_IGNR_REG_CMPL bit to delay issuing the new PLOGI until the queued REG_LOGIN and UNREG_LOGIN have been processed.

scsi: lpfc: Exit PRLI completion handling early if ndlp not in PRLI_ISSUE state In a large SAN testing configuration, frequent target port toggle tests are occasionally resulting in missing lun path rediscoveries. An outstanding PRLI can be inflight when a target RSCN dissappearance occurs, causing the driver to retry PRLIs using invalid rpi contexts. Fix by verifying that an ndlp's state was not restarted from PRLI_ISSUE due to an intermediate RSCN. If not in a valid state, early exit PRLI completion handling. The last follow up RSCN indicating target reappearance retriggers PLOGI/PRLI with a valid rpi context and is expected to succeed in LUN path rediscovery.

scsi: lpfc: Fix crash involving race between FLOGI timeout and devloss handler When a FLOGI completes with a sequence timeout error, a freed kref ptr dereference crash can occur due to a timing race involving ndlp referencing in lpfc_dev_loss_tmo_callbk. Fix by ensuring the driver accounts for an outstanding FLOGI when dev_loss is active. Also, don't remove the HBA_FLOGI_OUTSTANDING flag when the FLOGI is retried to allow the driver to handle the reference counts correctly in lpfc_dev_loss_tmo_handler.

scsi: lpfc: Revert RSCN_MEMENTO workaround for misbehaved configuration The RSCN_MEMENTO logic was to workaround a target that does not register both FCP and NVMe FC4 types at the same time. This caused the configuration to not produce a second RSCN for the NVMe FC4 type registration in a timely manner. The intention of the RSCN_MEMENTO flag was to always signal to try NVMe PRLI. However, there are other FCP-only target arrays in correctly behaved configurations that reject the NVMe PRLI followed by a LOGO leading to never rediscovering the target after an issue_lip (as LOGO causes a repeat of PLOGI/PRLIs). Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to fail while it exists only to succeed on a misbehaved config.

scsi: lpfc: Inhibit aborts if external loopback plug is inserted After running a short external loopback test, when the external loopback is removed and a normal cable inserted that is directly connected to a target device, the system oops in the llpfc_set_rrq_active() routine. When the loopback was inserted an FLOGI was transmit. As we're looped back, we receive the FLOGI request. The FLOGI is ABTS'd as we recognize the same wppn thus understand it's a loopback. However, as the ABTS sends address information the port is not set to (fffffe), the ABTS is dropped on the wire. A short 1 frame loopback test is run and completes before the ABTS times out. The looback is unplugged and the new cable plugged in, and the an FLOGI to the new device occurs and completes. Due to a mixup in ref counting the completion of the new FLOGI releases the fabric ndlp. Then the original ABTS completes and references the released ndlp generating the oops. Correct by no-op'ing the ABTS when in loopback mode (it will be dropped anyway). Added a flag to track the mode to recognize when it should be no-op'd.

scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

scsi: lpfc: SLI path split: Refactor lpfc_iocbq Currently, SLI3 and SLI4 data paths use the same lpfc_iocbq structure. This is a "common" structure but many of the components refer to sli-rev specific entities which can lead the developer astray as to what they actually mean, should be set to, or when they should be used. This first patch prepares the lpfc_iocbq structure so that elements common to both SLI3 and SLI4 data paths are more appropriately named, making it clear they apply generically. Fieldnames based on 'iocb' (sli3) or 'wqe' (sli4) which are actually generic to the paths are renamed to 'cmd': - iocb_flag is renamed to cmd_flag - lpfc_vmid_iocb_tag is renamed to lpfc_vmid_tag - fabric_iocb_cmpl is renamed to fabric_cmd_cmpl - wait_iocb_cmpl is renamed to wait_cmd_cmpl - iocb_cmpl and wqe_cmpl are combined and renamed to cmd_cmpl - rsvd2 member is renamed to num_bdes due to pre-existing usage The structure name itself will retain the iocb reference as changing to a more relevant "job" or "cmd" title induces many hundreds of line changes for only a name change. lpfc_post_buffer is also renamed to lpfc_sli3_post_buffer to indicate use in the SLI3 path only.

scsi: lpfc: Fix pt2pt NVMe PRLI reject LOGO loop When connected point to point, the driver does not know the FC4's supported by the other end. In Fabrics, it can query the nameserver. Thus the driver must send PRLIs for the FC4s it supports and enable support based on the acc(ept) or rej(ect) of the respective FC4 PRLI. Currently the driver supports SCSI and NVMe PRLIs. Unfortunately, although the behavior is per standard, many devices have come to expect only SCSI PRLIs. In this particular example, the NVMe PRLI is properly RJT'd but the target decided that it must LOGO after seeing the unexpected NVMe PRLI. The LOGO causes the sequence to restart and login is now in an infinite failure loop. Fix the problem by having the driver, on a pt2pt link, remember NVMe PRLI accept or reject status across logout as long as the link stays "up". When retrying login, if the prior NVMe PRLI was rejected, it will not be sent on the next login.

These fixed delay functions are causing long delays in the driver's worker thread when processing discovery I/Os in a serialized fashion, which is then triggering mailbox timeout errors artificially. To fix this, don't wait on the DA_ID request to complete and call wait_event_timeout to allow the vport delete thread to make progress on an event driven basis rather than fixing the wait time.

scsi: lpfc: Fix leaked lpfc_dmabuf mbox allocations with NPIV During rmmod testing, messages appeared indicating lpfc_mbuf_pool entries were still busy. This situation was only seen doing rmmod after at least 1 vport (NPIV) instance was created and destroyed. The number of messages scaled with the number of vports created. When a vport is created, it can receive a PLOGI from another initiator Nport. When this happens, the driver prepares to ack the PLOGI and prepares an RPI for registration (via mbx cmd) which includes an mbuf allocation. During the unsolicited PLOGI processing and after the RPI preparation, the driver recognizes it is one of the vport instances and decides to reject the PLOGI. During the LS_RJT preparation for the PLOGI, the mailbox struct allocated for RPI registration is freed, but the mbuf that was also allocated is not released. Fix by freeing the mbuf with the mailbox struct in the LS_RJT path. As part of the code review to figure the issue out a couple of other areas where found that also would not have released the mbuf. Those are cleaned up as well.

scsi: lpfc: Fix non-recovery of remote ports following an unsolicited LOGO A commit introduced formal regstration of all Fabric nodes to the SCSI transport as well as REG/UNREG RPI mailbox requests. The commit introduced the NLP_RELEASE_RPI flag for rports set in the lpfc_cmpl_els_logo_acc() routine to help clean up the RPIs. This new code caused the driver to release the RPI value used for the remote port and marked the RPI invalid. When the driver later attempted to re-login, it would use the invalid RPI and the adapter rejected the PLOGI request. As no login occurred, the devloss timer on the rport expired and connectivity was lost. This patch corrects the code by removing the snippet that requests the rpi to be unregistered. This change only occurs on a node that is already marked to be rediscovered. This puts the code back to its original behavior, preserving the already-assigned rpi value (registered or not) which can be used on the re-login attempts.

scsi: lpfc: Allow fabric node recovery if recovery is in progress before devloss A link bounce to a slow fabric may observe FDISC response delays lasting longer than devloss tmo. Current logic decrements the final fabric node kref during a devloss tmo event. This results in a NULL ptr dereference crash if the FDISC completes for that fabric node after devloss tmo. Fix by adding the NLP_IN_RECOV_POST_DEV_LOSS flag, which is set when devloss tmo triggers and we've noticed that fabric node recovery has already started or finished in between the time lpfc_dev_loss_tmo_callbk queues lpfc_dev_loss_tmo_handler. If fabric node recovery succeeds, then the driver reverses the devloss tmo marked kref put with a kref get. If fabric node recovery fails, then the final kref put relies on the ELS timing out or the REG_LOGIN cmpl routine.

scsi: lpfc: Allow PLOGI retry if previous PLOGI was aborted A remote nport can stop responding to PLOGI beyond the ELS I/O timeout under some fault conditions. When this happens, the non-response triggers a dev_loss_tmo event from the transport which causes the driver to abort the PLOGI and stop any retries. This was due to a policy in the ELS completion handler whenever an ELS was terminated due to driver request. Revise the ELS completion path to detect PLOGIs that were aborted and allow retries.

scsi: lpfc: Don't remove ndlp on PRLI errors in P2P mode In pt-2-pt mode, the initiator does not log into the target after a PRLI error. In pt-2-pt mode, the target responded to the PRLI by sending a LOGO. The LOGO causes all ELS and I/Os to be aborted. This caused the PRLI to fail. The PRLI completion path caused the discovery node to be dropped to avoid being stick in an UNUSED (not logged in) state. As the node was dropped there is no retry of the login and as it is pt-2-pt, there is no RSCN to retrigger discovery. Thus the other end is not seen by the OS. Fix by ensuring the discovery node is not dropped if connecting pt-2-pt. This will cause PLOGI to be retried.

scsi: lpfc: Fix hang on unload due to stuck fport node A test scenario encountered an unload hang while an FLOGI ELS was in flight when a link down condition occurred. The driver fails unload as it never releases the fport node. For most nodes, when the link drops, devloss tmo is started and the timeout will cause the final node release. For the Fport, as it has not yet registered with the SCSI transport, there is no devloss timer to be started, so there is no final release. Additionally, the link down sequence causes ABORTS to be issued for pending ELS's. The completions from the ABORTS perform the release of node references. However, as the adapter is being reset to be unloaded, those completions will never occur. Fix by the following: - In the ELS cleanup, recognize when unloading and place the ELS's on a different list that immediately cleans up/completes the ELS's. It's recognized that this condition primarily affects only the fport, with other ports having normal clean up logic that handles things. - Resolve the devloss issue by, when cleaning up nodes on after link down, recognizing when the fabric node does not have a completed state (its state is UNUSED) and removing a reference so the node can delete after the ELS reference is released.

scsi: lpfc: Fix premature rpi release for unsolicited TPLS and LS_RJT A test scenario has a target issuing a TPLS after accepting the driver's PRLI. TPLS is not supported by the driver so it rejects the ELS. However, the reject was only happening on the primary N_Port. If the TPLS was to a NPIV vport, not only would it reject the ELS, but it would act on the TPLS, starting devloss, then unregister from the SCSI transport and release the node. When devloss expired, it would access the node again and cause a page faul. Fix by altering the NPIV code to recognize that a correctly registered node can reject unsolicited ELS I/O and to not unregister with the SCSI transport and tear the node down. Add a check of the fc4_xpt_flags so that only a zero value allows the unreg and teardown.

scsi: lpfc: Don't release final kref on Fport node while ABTS outstanding In a rarely executed path, FLOGI failure, there is a refcounting error. If FLOGI completed with an error, typically a timeout, the initial completion handler would remove the job reference. However, the job completion isn't the actual end of the job/exchange as the timeout usually initiates an ABTS, and upon that ABTS completion, a final completion is sent. The driver removes the reference again in the final completion. Thus the imbalance. In the buggy cases, if there was a link bounce while the delayed response is outstanding, the fport node may be referenced again but there was no additional reference as it is already present. The delayed completion then occurs and removes the last reference freeing the node and causing issues in the link up processed that is using the node. Fix this scenario by removing the snippet that removed the reference in the initial FLOGI completion. The bad snippet was poorly trying to identify the FLOGI as OK to do so by realizing the node was not registered with either SCSI or NVMe transport.

scsi: lpfc: Fix CPU to/from endian warnings introduced by ELS processing The kernel test robot reported the following sparse warning: ".../lpfc_els.c:3984:25: sparse: sparse: cast from restricted __be16" For the error being flagged, using be32_to_cpu() on a be16 data type, it was simple enough. But a review of other elements and warnings were also evaluated. This patch corrected several items in the original patch: - Using be32_to_cpu() on a be16 data type - cpu_to_le32() used on a std uint32_t (CPU) data type. Note: This is a byte array, but stored in LE layout by hardware at 32-bit boundaries. So it possibly needed conversion. - Using cpu_to_le32() on a std uint16_t and assigned to a char typeA - Using le32_to_cpu() on a le16 type - Missing cpu_to_le16() on an assignment Link: https://lore.kernel.org/r/20210830231243.6227-1-jsmart2021@gmail.com Fixes: 9064aeb2df8e ("scsi: lpfc: Add EDC ELS support") Reported-by: kernel test robot <lkp@intel.com> Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

scsi: lpfc: Skip reg_vpi when link is down for SLI3 in ADISC cmpl path During RSCN storms, some instances of LIP on SLI-3 adapters lead to a situation where FLOGIs keep failing with firmware indicating an illegal command error code. This situation was preceded by an ADISC completion that was processed while the link was down. This path on SLI-3 performs a CLEAR_LA and attempts to activate a VPI with REG_VPI. Later, as the FLOGI completes, it's no longer in sync with the VPI state. In SLI-3 it is illegal to have an active VPI during FLOGI. Resolve by circumventing the SLI-3 path that performs the CLEAR_LA and REG_VPI. The path will be taken after the FLOGI after the next Link Up.

scsi: lpfc: Delay unregistering from transport until GIDFT or ADISC completes On an RSCN event, the nodes specified in RSCN payload and in MAPPED state are moved to NPR state in order to revalidate the login. This triggers an immediate unregister from SCSI/NVMe backend. The assumption is that the node may be missing. The re-registration with the backend happens after either relogin (PLOGI/PRLI; if ADISC is disabled or login truly lost) or when ADISC completes successfully (rediscover with ADISC enabled). However, the NVMe-FC standard provides for an RSCN to be triggered when the remote port supports a discovery controller and there was a change of discovery log content. As the remote port typically also supports storage subsystems, this unregister causes all storage controller connections to fail and require reconnect. Correct by reworking the code to ensure that the unregistration only occurs when a login state is truly terminated, thereby leaving the NVMe storage controllers in place. The changes made are: - Retain node state in ADISC_ISSUE when scheduling ADISC ELS retry. - Do not clear wwpn/wwnn values upon ADISC failure. - Move MAPPED nodes to NPR during RSCN processing, but do not unregister with transport. On GIDFT completion, identify missing nodes (not marked NLP_NPR_2B_DISC) and unregister them. - Perform unregistration for nodes that will go through ADISC processing if ADISC completion fails. - Successful ADISC completion will move node back to MAPPED state.

scsi: lpfc: Fix node handling for Fabric Controller and Domain Controller During link bounce testing, RPI counts were seen to differ from the number of nodes. For fabric and domain controllers, a temporary RPI is assigned, but the code isn't registering it. If the nodes do go away, such as on link down, the temporary RPI isn't being released. Change the way these two fabric services are managed, make them behave like any other remote port. Register the RPI and register with the transport. Never leave the nodes in a NPR or UNUSED state where their RPI is in limbo. This allows them to follow normal dev_loss_tmo handling, RPI refcounting, and normal removal rules. It also allows fabric I/Os to use the RPI for traffic requests. Note: There is some logic that still has a couple of exceptions when the Domain controller (0xfffcXX). There are cases where the fabric won't have a valid login but will send RDP. Other times, it will it send a LOGO then an RDP. It makes for ad-hoc behavior to manage the node. Exceptions are documented in the code.

scsi: lpfc: Fix Node recovery when driver is handling simultaneous PLOGIs When lpfc is handling a solicited and unsolicited PLOGI with another initiator, the remote initiator is never recovered. The node for the initiator is erroneouosly removed and all resources released. In lpfc_cmpl_els_plogi(), when lpfc_els_retry() returns a failure code, the driver is calling the state machine with a device remove event because the remote port is not currently registered with the SCSI or NVMe transports. The issue is that on a PLOGI "collision" the driver correctly aborts the solicited PLOGI and allows the unsolicited PLOGI to complete the process, but this process is interrupted with a device_rm event. Introduce logic in the PLOGI completion to capture the PLOGI collision event and jump out of the routine. This will avoid removal of the node. If there is no collision, the normal node removal will occur.

The message occurs when a PLOGI is received before the driver is notified of FLOGI completion. The FLOGI completion failure causes discovery to be triggered for a second time. The discovery timer is restarted but no new discovery activity is initiated, thus the timeout message eventually appears.

Add code to FLOGI completion to detect that discovery has progressed and exit the FLOGI handling (noop'ing it).

scsi: lpfc: Fix unreleased RPIs when NPIV ports are created While testing NPIV and watching logins and used RPI levels, it was seen the used RPI count was much higher than the number of remote ports discovered. Code inspection showed that remote port removals on any NPIV instance are releasing the RPI, but not performing an UNREG_RPI with the adapter thus the reference counting never fully drops and the RPI is never fully released. This was happening on NPIV nodes due to a log of fabric ELS's to fabric addresses. This lack of UNREG_RPI was introduced by a prior node rework patch that performed the UNREG_RPI as part of node cleanup. To resolve the issue, do the following: - Restore the RPI release code, but move the location to so that it is in line with the new node cleanup design. - NPIV ports now release the RPI and drop the node when the caller sets the NLP_RELEASE_RPI flag. - Set the NLP_RELEASE_RPI flag in node cleanup which will trigger a release of RPI to free pool. - Ensure there's an UNREG_RPI at LOGO completion so that RPI release is completed. - Stop offline_prep from skipping nodes that are UNUSED. The RPI may not have been released. - Stop the default RPI handling in lpfc_cmpl_els_rsp() for SLI4. - Fixed up debugfs RPI displays for better debugging.

scsi: lpfc: Fix reference counting errors in lpfc_cmpl_els_rsp() Call traces are being seen that result from a nodelist structure ref counting error. They are typically seen after transmission of an LS_RJT ELS response. Aged code in lpfc_cmpl_els_rsp() calls lpfc_nlp_not_used() which, if the ndlp reference count is exactly 1, will decrement the reference count. Previously lpfc_nlp_put() was within lpfc_els_free_iocb(), and the 'put' within the free would only be invoked if cmdiocb->context1 was not NULL. Since the nodelist structure reference count is decremented when exiting lpfc_cmpl_els_rsp() the lpfc_nlp_not_used() calls are no longer required. Calling them is causing the reference count issue. Fix by removing the lpfc_nlp_not_used() calls.

scsi: lpfc: Fix ADISC handling that never frees nodes While testing target port swap test with ADISC enabled, several nodes remain in UNUSED state. These nodes are never freed and rmmod hangs for long time before finising with "0233 Nodelist not empty" error. During PLOGI completion lpfc_plogi_confirm_nport() looks for existing nodes with same WWPN. If found, the existing node is used to continue discovery. The node on which plogi was performed is freed. When ADISC is enabled, an ADISC els request is triggered in response to an RSCN. It's possible that the ADISC may be rejected by the remote port causing the ADISC completion handler to clear the port and node name in the node. If this occurs, if a PLOGI is received it causes a node lookup based on wwpn to now fail, causing the port swap logic to kick in which allocates a new node and swaps to it. This effectively orphans the original node structure. Fix the situation by detecting when the lookup fails and forgo the node swap and node allocation by using the node on which the PLOGI was issued.

scsi: lpfc: Fix dropped FLOGI during pt2pt discovery recovery When connected in pt2pt mode, there is a scenario where the remote port significantly delays sending a response to our FLOGI, but acts on the FLOGI it sent us and proceeds to PLOGI/PRLI. The FLOGI ends up timing out and kicks off recovery logic. End result is a lot of unnecessary state changes and lots of discovery messages being logged. Fix by terminating the FLOGI and noop'ing its completion if we have already accepted the remote ports FLOGI and are now processing PLOGI.

scsi: lpfc: Implement health checking when aborting I/O Several errors have occurred where the adapter stops or fails but does not raise the register values for the driver to detect failure. Thus driver is unaware of the failure. The failure typically results in I/O timeouts, the I/O timeout handler failing (after several seconds), and the error handler escalating recovery policy and resulting in more errors. Eventually, the driver is in a position where things have spiraled and it can't do recovery because other recovery ops are still outstanding and it becomes unusable. Resolve the situation by having the I/O timeout handler (actually a els, SCSI I/O, NVMe ls, or NVMe I/O timeout), in addition to aborting the I/O, perform a mailbox command and look for a response from the hardware. If the mailbox command fails, it will mark the adapter offline and then invoke the adapter reset handler to clean up. The new I/O timeout test will be limited to a test every 5s. If there are multiple I/O timeouts concurrently, only the 1st I/O timeout will generate the mailbox command. Further testing will only occur once a timeout occurs after a 5s delay from the last mailbox command has expired.

scsi: lpfc: Fix PLOGI S_ID of 0 on pt2pt config Under some pt2pt situations, the other end of the link may issue a LOGO after successfully completing PLOGI and assigning addresses to the port. Thus the driver may attempt a new PLOGI to re-create the login, but the LOGO handling cleared the address back to 0. Once this happens, the other end, which may be address 0, gets all confused and this cannot be resolved without an administrative action to bounce the link. Fix by assuming that address assignment only occurs on the 1st PLOGI after link up, and regardless of login state, the address assignment sticks. The FC standards aren't particularly clear in this situation (it only describes initial PLOGI), but there is nothing that contradicts this and behaviors on the devices tested appears to conform to the understanding. Thus, don't reset the port address to 0 as part of LOGO handling. Port addresses will only reset on link down.

scsi: lpfc: Convert abort handling to SLI-3 and SLI-4 handlers This patch reworks the abort interfaces such that SLI-3 retains the iocb-based formatting and completions and SLI-4 now uses native WQEs and completion routines. The following changes are made: - The code is refactored from a confusing 2 routine sequence of xx_abort_iotag_issue(), which creates/formats and abort cmd, and xx_issue_abort_tag(), which then issues and handles the completion of the abort cmd - into a single interface of xx_issue_abort_iotag(). The new interface will determine whether SLI-3 or SLI-4 and then call the appropriate handler. A completion handler can now be specified to address the differences in completion handling. Note: original code is all iocb based, with SLI-4 converting to SLI-3 for the SCSI/ELS path, and NVMe natively using wqes. - The SLI-3 side is refactored: The older iocb-base lpfc_sli_issue_abort_iotag() routine is combined with the logic of lpfc_sli_abort_iotag_issue() as well as the iocb-specific code in lpfc_abort_handler() and lpfc_sli_abort_iocb() to create the new single SLI-3 abort routine that formats and issues the iocb. - The SLI-4 side is refactored and added to: The native WQE abort code in NVMe is moved to the new SLI-4 issue_abort_iotag() routine. Items in SCSI that set fields not set by NVMe is migrated into the new routine. Thus the routine supports NVMe and SCSI initiators. The nvmet block (target) formats the abort slightly different (like the old NVMe initiator) thus it has its own prep routine stolen from NVMe initiator and it retains the current code it has for issuing the WQE (does not use the commonized routine the initiators do). SLI-4 completion handlers were also added. - lpfc_abort_handler now becomes a wrapper that determines whether SLI-3 or SLI-4 and calls the proper abort handler.

scsi: lpfc: Fix NPIV discovery and Fabric Node detection While testing NPIV and link bounces, the vport would not show a fabric node for the F_Port, would not transition into NPR state during a link fault, or leave the FDMI node untouched during error injection. Cause for this was determined to be an inconsistent manner in which F_Port, Nameserver, and FDMI controller nodes were created and linked. In some cases, the nodes would never be unregistered from the transport, leaving references active. In other cases, the fabric nodes may register with the transport multiple times while still registered. The following changes were made: - Fix the FDISC issue routine, which starts vport (re)creation, to mark the F_Port as a fabric node (NLP_FABRIC) and allow the F_Port node to fully be created and show up in the node list. - When remote ports are cleaned up on vport termination, cleanup the nameserver and FDMI controller nodes on the vport so they unregister from the transport. - On link bounces, don't exclude the NPIV Fabric remote ports from transitioning to the NPR state, allowing them to avoid re-registration if already registered.

scsi: lpfc: Unsolicited ELS leaves node in incorrect state while dropping it When a target swap happens, under certain conditions the node sends a LOGO. The unsolicited ELS logic responds with a reject. The logic may allocate a new node to handle this. Afterward, the new nodes are dropped incorrectly leaving them in a mis-matched state and refcounting causes a use-after-free situation leading to a crash. It is also possible that the unsolicited els handling finds a node which is in an UNUSED state. The handling moves these nodes to NPR state with a refcount of 1. Although the end of the discovery logic assumes a final put will free such a node, there are codes paths which could increment the reference count, thus the node is in NPR state and not released. Eventually this mismatch in state and refcount leads to premature release of the node causing a crash. Fix by always using the discovery engine DEVICE RM event to decrement and release the nodes (rather than explicit code that tried to do it before). This will take care of moving the node to the UNUSED state and then removes the final ref count. If there is a trigger to reuse this node, the transition from the UNUSED state clearly indicates that the initial reference is then incremented and use can continue.

scsi: lpfc: Fix refcounting around SCSI and NVMe transport APIs Due to bug history and code review, the node reference counting approach in the driver isn't implemented consistently with how the scsi and nvme transport perform registrations and unregistrations and their callbacks. This resulted in many bad/stale node pointers. Reword the driver so that reference handling is performed as follows: - The initial node reference is taken on structure allocation - Take a reference on any add/register call to the transport - Remove a reference on any delete/unregister call to the transport - After the node has fully removed from both the SCSI and NVMEe transports (dev_loss_callbacks have called back) call the discovery engine DEVICE_RM event which will remove the final reference and release the node structure. - Alter dev_loss handling when a vport or base port is unloading. - Remove the put_node handling - no longer needed. - Rewrite the vport_delete handling on reference counts.

scsi: lpfc: Fix removal of SCSI transport device get and put on dev structure The lpfc driver is calling get_device and put_device on scsi_fc_transport device structure. When this code was removed, the driver triggered an oops in "scsi_is_host_dev" when the first SCSI target was unregistered from the transport. The reason the calls were necessary is that the driver is calling scsi_remove_host too early, before the target rports are unregistered and the scsi devices disconnected from the scsi_host. The fc_host was torn down during fc_remove_host. Fix by moving the lpfc_pci_remove_one_s3/s4 calls to scsi_remove_host to after the nodes are cleaned up. Remove the get_device and put_device calls and the supporting code.

scsi: lpfc: Rework locations of ndlp reference taking Now that the driver has gone to a normal ref interface (with no odd logic) the discovery logic needs to be updated to reworked so that it properly takes references when it should and give them up when it should. Rework the driver for the following get/put model: - Move gets to just before an I/O is issued. Add gets for places where an I/O was issued without one. - Ensure that failures from lpfc_nlp_get() are handled by the driver. - Check and fix the placement of lpfc_nlp_puts relative to io completions. Note: some of these paths may not release the reference on the exact io completion as the reference is held as the code takes another step in the discovery thread and which may cause another io to be issued. - Rearrange some code for error processing and calling lpfc_nlp_put. - Fix some places of incorrect reference freeing that was causing the premature releasing of the structure. - Nvmet plogi handling performs unreg_rpi's. The reference counts were unbalanced resulting in premature node removal. In some cases this caused loss of node discovery. Corrected the reftaking around nvmet plogis. Nodes that experience devloss now get released from the node list now that there is a proper reference taking.

scsi: lpfc: Rework remote port ref counting and node freeing When a remote port is disconnected and disappears, its node structure (ndlp) stays allocated and on a vport node list. While on the list it can be matched, thus requires validation checks on state to be added in numerous code paths. If the node comes back, its possible for there to be multiple node structures for the same device on the vport node list. There is no reason to keep the node structure around after it is no longer in existence, and the current implementation creates problems for itself (multiple nodes) and lots of unnecessary code for state validation. Additionally, the reference taking on the node structure didn't follow the normal model used by the kernel kref api. It included lots of odd logic to match state with reference count. The combination of this odd logic plus the way it was implicitly used in the discovery engine made its reference taking implementation suspect and extremely hard to follow. Change the driver such that the reference taking routines are now normal ref increments/decrements and callout on refcount=0. With this in place, the rework can be done such that the node structure is fully removed and deallocated when the remote port no longer exists and all references are removed. This removal logic, and the basic ref counting are intrically tied, thus in a single patch.

scsi: lpfc: Fix FLOGI/PLOGI receive race condition in pt2pt discovery The driver is unable to successfully login with remote device. During pt2pt login, the driver completes its FLOGI request with the remote device having WWN precedence. The remote device issues its own (delayed) FLOGI after accepting the driver's and, upon transmitting the FLOGI, immediately recognizes it has already processed the driver's FLOGI thus it transitions to sending a PLOGI before waiting for an ACC to its FLOGI. In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI being received and an ACC sent. The issue is that the PLOGI reception occurs before the response from the adapter from the FLOGI ACC is received. Processing of the PLOGI sets state flags to perform the REG_RPI mailbox command and proceed with the rest of discovery on the port. The same completion routine used by both FLOGI and PLOGI is generic in nature. One of the things it does is clear flags, and those flags happen to drive the rest of discovery. So what happened was the PLOGI processing set the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC completes it doesn't see the flags and stops. Fix by modifying the generic completion routine to not clear the rest of discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated with performing a mailbox command as part of its handling. For things such as FLOGI ACC, there isn't a subsequent action to perform with the adapter, thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI upon completion, thus there is a mailbox cmd ptr.

scsi: lpfc: Fix retry of PRLI when status indicates its unsupported With port bounce/address swaps and timing between initiator GID queries vs remote port FC4 support registrations, the driver may be in a situation where it sends PRLIs for both FCP and NVME even though the target may not support one of the protocols. In this case, the remote port will reject the PRLI and usually indicate it does not support the request. However, the driver currently ignores the status of the failure and immediately retries the PRLI, which is pointless. In the case of this one remote port, the reception of the PRLI retry caused it to decide to send a LOGO. The LOGO restarted the process and the same results happened. It made the remote port undiscoverable to either protocol. Add logic to detect the non-support status and not attempt the retry of the PRLI.

scsi: lpfc: Add an internal trace log buffer The current logging methods typically end up requesting a reproduction with a different logging level set to figure out what happened. This was mainly by design to not clutter the kernel log messages with things that were typically not interesting and the messages themselves could cause other issues. When looking to make a better system, it was seen that in many cases when more data was wanted was when another message, usually at KERN_ERR level, was logged. And in most cases, what the additional logging that was then enabled was typically. Most of these areas fell into the discovery machine. Based on this summary, the following design has been put in place: The driver will maintain an internal log (256 elements of 256 bytes). The "additional logging" messages that are usually enabled in a reproduction will be changed to now log all the time to the internal log. A new logging level is defined - LOG_TRACE_EVENT. When this level is set (it is not by default) and a message marked as KERN_ERR is logged, all the messages in the internal log will be dumped to the kernel log before the KERN_ERR message is logged. There is a timestamp on each message added to the internal log. However, this timestamp is not converted to wall time when logged. The value of the timestamp is solely to give a crude time reference for the messages.

scsi: lpfc: Fix lpfc_nodelist leak when processing unsolicited event In order to create or activate a new node, lpfc_els_unsol_buffer() invokes lpfc_nlp_init() or lpfc_enable_node() or lpfc_nlp_get(), all of them will return a reference of the specified lpfc_nodelist object to "ndlp" with increased refcnt. When lpfc_els_unsol_buffer() returns, local variable "ndlp" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling path of lpfc_els_unsol_buffer(). When "ndlp" in DEV_LOSS, the function forgets to decrease the refcnt increased by lpfc_nlp_init() or lpfc_enable_node() or lpfc_nlp_get(), causing a refcnt leak. Fix this issue by calling lpfc_nlp_put() when "ndlp" in DEV_LOSS.

scsi: lpfc: add RDF registration and Link Integrity FPIN logging This patch modifies lpfc to register for Link Integrity events via the use of an RDF ELS and to perform Link Integrity FPIN logging. Specifically, the driver was modified to: - Format and issue the RDF ELS immediately following SCR registration. This registers the ability of the driver to receive FPIN ELS. - Adds decoding of the FPIN els into the received descriptors, with logging of the Link Integrity event information. After decoding, the ELS is delivered to the scsi fc transport to be delivered to any user-space applications. - To aid in logging, simple helpers were added to create enum to name string lookup functions that utilize the initialization helpers from the fc_els.h header. - Note: base header definitions for the ELS's don't populate the descriptor payloads. As such, lpfc creates it's own version of the structures, using the base definitions (mostly headers) and additionally declaring the descriptors that will complete the population of the ELS.

scsi: lpfc: Fix list corruption in lpfc_sli_get_iocbq After study, it was determined there was a double free of a CT iocb during execution of lpfc_offline_prep and lpfc_offline. The prep routine issued an abort for some CT iocbs, but the aborts did not complete fast enough for a subsequent routine that waits for completion. Thus the driver proceeded to lpfc_offline, which releases any pending iocbs. Unfortunately, the completions for the aborts were then received which re-released the ct iocbs. Turns out the issue for why the aborts didn't complete fast enough was not their time on the wire/in the adapter. It was the lpfc_work_done routine, which requires the adapter state to be UP before it calls lpfc_sli_handle_slow_ring_event() to process the completions. The issue is the prep routine takes the link down as part of it's processing. To fix, the following was performed: - Prevent the offline routine from releasing iocbs that have had aborts issued on them. Defer to the abort completions. Also means the driver fully waits for the completions. Given this change, the recognition of "driver-generated" status which then releases the iocb is no longer valid. As such, the change made in the commit 296012285c90 is reverted. As recognition of "driver-generated" status is no longer valid, this patch reverts the changes made in commit 296012285c90 ("scsi: lpfc: Fix leak of ELS completions on adapter reset") - Modify lpfc_work_done to allow slow path completions so that the abort completions aren't ignored. - Updated the fdmi path to recognize a CT request that fails due to the port being unusable. This stops FDMI retries. FDMI will be restarted on next link up.

scsi: lpfc: Add NVMe sequence level error recovery support FC-NVMe-2 added support for sequence level error recovery in the FC-NVME protocol. This allows for the detection of errors and lost frames and immediate retransmission of data to avoid exchange termination, which escalates into NVMeoFC connection and association failures. A significant RAS improvement. The driver is modified to indicate support for SLER in the NVMe PRLI is issues and to check for support in the PRLI response. When both sides support it, the driver will set a bit in the WQE to enable the recovery behavior on the exchange. The adapter will take care of all detection and retransmission.

scsi: lpfc: Fix driver nvme rescan logging In situations where zoning is not being used, thus NVMe initiators see other NVMe initiators as well as NVMe targets, a link bounce on an initiator will cause the NVMe initiators to spew "6169" State Error messages. The driver is not qualifying whether the remote port is a NVMe targer or not before calling the lpfc_nvme_rescan_port(), which validates the role and prints the message if its only an NVMe initiator. Fix by the following: - Before calling lpfc_nvme_rescan_port() ensure that the node is a NVMe storage target or a NVMe discovery controller. - Clean up implementation of lpfc_nvme_rescan_port. remoteport pointer will always be NULL if a NVMe initiator only. But, grabbing of remoteport pointer should be done under lock to coincide with the registering of the remote port with the fc transport.

scsi: lpfc: Fix FLOGI handling across multiple link up/down conditions It's possible for the driver to initiate an FLOGI and before it completes, another link down/up transition occurs requiring a new FLOGI. Currently, nothing is done to abort/noop the older FLOGI request to the adapter, so if this transition occurs and the FLOGI completion is received after the link down/up transition, the driver may erroneously act on the older FLOGI. In most cases, the adapter properly terminates/fails the FLOGI, but there is a timing condition where the FLOGI may complete on the wire prior to the transition, but the response may not be seen/processed by the driver before the driver sees the link transition. Fix by having the link down handler in the driver run through any outstanding ELS's and change the completion handler of the ELS so that it will be no-op'd and released.

scsi: lpfc: Defer LS_ACC to FLOGI on point to point logins The current discovery state machine the driver treated FLOGI oddly. When point to point, an FLOGI is to be exchanged by the two ports, with the port with the most significant WWN then proceeding with PLOGI. The implementation in the driver was keyed to closely with "what have I sent", not with what has happened between the two endpoints. Thus, it blatantly would ACC an FLOGI, but reject PLOGI's until it had its FLOGI ACC'd. The problem is - the sending of FLOGI may be delayed for some reason, or the response to FLOGI held off by the other side. In the failing situation the other side sent an FLOGI, which was ACC'd, then sent PLOGIs which were then rjt'd until the retry count for the PLOGIs were exceeded and the port gave up. The FLOGI may have been very late in transmit, or the response held off until the PLOGIs failed. Given the other port had the higher WWN, no PLOGIs would occur and communication stopped. Correct the situation by changing the FLOGI handling. Defer any response to an FLOGI until the driver has sent its FLOGI as well. Then, upon either completion of the sent FLOGI, or upon sending an ACC to a received FLOGI (which may be received before or just after FLOGI was sent). the driver will act on who has the higher WWN. if the other port does, the driver will noop any handling of an FLOGI response (if outstanding) and wait for PLOGI. If the local port does, the driver will transition to sending PLOGI and will noop any action on responding to an FLOGI (if not yet received). Fortunately, to implement this, it only took another state flag and deferring any FLOGI response if the FLOGI has yet to be transmit. All subsequent actions were already in place.

scsi: lpfc: ls_rjt erroneus FLOGIs In some link initialization sequences, the fw generates an erroneous FLOGI payload to the driver without an intervening link bounce. The driver, when it sees a 2nd FLOGI without an intervening link bounce, automatically performs a link bounce. In this, the link bounce causes the situate to repeat and in a nasty loop of link bounces. Resolve the issue by validating the FLOGI payload. The erroneous FLOGI will contain VVL signatures that are not normal. When the driver sees these, it will simply reject the flogi rather than bouncing the link.

scsi: lpfc: rport port swap discovery issue. Two initiator ports were cable swapped and after swap both went down. The driver internally swaps the nlp nodes based on matching node wwn's but not the same nport id as before. After detecting a change in the nodes RPI, the driver sends an UNREG_RPI command and clears the NLP_RPI_REGISTERED flag, then swaps the node information with the other node. But the other node's NLP_RPI_REGISTERED flag is also cleared, but it is done so without an UNREG_RPI being sent, which causes the later REG_RPI for that other node to fail as the hardware believes its still registered. Additionally, if the node swap occurred while the two nodes had PLOGI's in flight, the fc4_types weren't properly getting swapped such that when the PLOGIs commpleted and PRLI's were then sent, the PRLI's acted on bad protocol types so the PRLI was for the wrong protocol. NVME devices saw SCSI FCP PRLIs and vice versa. Clean up the node swap so that the NLP_RPI_REGISTERED flag is handled properly.

scsi: lpfc: Fix discovery failures during port failovers with lots of vports The driver is getting hit with 100s of RSCNs during remote port address changes. Each of those RSCN's ends up generating UNREG_RPI and REG_PRI mailbox commands. The discovery engine within the driver doesn't wait for the mailbox command completions. Instead it sets state flags and moves forward. At some point, there's a massive backlog of mailbox commands which take time for the adapter to process. Additionally, it appears there were duplicate events from the switch so the driver generated duplicate mailbox commands for the same remote port. During this window, failures on PLOGI and PRLI ELS's are see as the adapter is rejecting them as they are for remote ports that still have pending mailbox commands. Streamline the discovery engine so that PLOGI log checks for outstanding UNREG_RPIs and defer the processing until the commands complete. This better synchronizes the ELS transmission vs the RPI registrations. Filter out multiple UNREG_RPIs being queued up for the same remote port. Beef up log messages in this area.

scsi: lpfc: Fix LOGO/PLOGI handling when triggerd by ABTS Timeout event After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to re-establish the login. An nlp_type check in the LOGO completion handler failed to restart discovery for NVME targets. Revised the nlp_type check for NVME as well as SCSI. While reviewing the LOGO handling a few other issues were seen and were addressed: - Better lock synchronization around ndlp data types - When the ABTS times out, unregister the RPI before sending the LOGO so that all local exchange contexts are cleared and nothing received while awaiting LOGO/PLOGI handling will be accepted. - LOGO handling optimized to: Wait only R_A_TOV for a response. It doesn't need to be retried on timeout. If there wasn't a response, a PLOGI will be sent, thus an implicit logout applies as well when the other port sees it. If there is a response, any kind of response is considered "good" and the XRI quarantined for a exchange qualifier window. - PLOGI is issued as soon a LOGO state is resolved.

scsi: lpfc: Correct irq handling via locks when taking adapter offline When taking the board offline while performing i/o, unsafe locking errors occurred and irq level isn't properly managed. In lpfc_sli_hba_down, spin_lock_irqsave(&phba->hbalock, flags) does not disable softirqs raised from timer expiry. It is possible that a softirq is raised from the lpfc_els_retry_delay routine and recursively requests the same phba->hbalock spinlock causing deadlock. Address the deadlocks by creating a new port_list lock. The softirq behavior can then be managed a level deeper into the calling sequences.

scsi: lpfc: Fix driver not recovering NVME rports during target link faults During target-side port faults, the driver would not recover all target port logins. This resulted in a loss of nvme device discovery. The driver is coded to wait for all GID_FT requests to complete before restarting discovery. A fault is seen where the outstanding GIT_FT counts are not properly decremented, thus discovery would never start. Another fault was found in the clearing of the gidft_inp counter that would be skipped in this condition. And a third fault found with lpfc_nvme_register_port that would remove a reverence on the ndlp which then allows a node swap on a port address change to prematurely remove the reference and release the ndlp. The following changes are made: - Correct the decrementing of the outstanding GID_FT counters. - In RSCN handling, no longer zero the counter before calling to issue another GID_FT. - No longer remove the reference on the dlp when the ndlp->nrport value is not yet null.

scsi: lpfc: Fix SCSI LUN discovery when SCSI and NVME enabled When enabled for both SCSI and NVME support, and connected pt2pt to a SCSI only target, the driver nodelist entry for the remote port is left in PRLI_ISSUE state and no SCSI LUNs are discovered. Works fine if only configured for SCSI support. Error was due to some of the prli points still reflecting the need to send only 1 PRLI. On a lot of fabric configs, targets were NVME only, which meant the fabric-reported protocol attributes were only telling the driver one protocol or the other. Thus things worked fine. With pt2pt, the driver must send a PRLI for both protocols as there are no hints on what the target supports. Thus pt2pt targets were hitting the multiple PRLI issues. Complete the dual PRLI support. Track explicitly whether scsi (fcp) or nvme prli's have been sent. Accurately track protocol support detected on each node as reported by the fabric or probed by PRLI traffic.

NVMET should not respond to RSCN including allocating new ndlps so this code was conditionalized when nvmet_support is true. The check for NLP_RCV_PLOGI in lpfc_setup_disc_node was moved below the check for nvmet_support to allow the NVMET to recover initiator nodes correctly. The implicit logo was introduced with lpfc_rcv_plogi when NVMET gets a PLOGI on an ndlp in UNMAPPED state. The RSCN handling was modified to not respond to an RSCN in NVMET. Instead NVMET sends a GID_FT and determines if an NVMEP_INITIATOR it has is UNMAPPED but no longer in the zone membership.

scsi: lpfc: NVME Initiator: Base modifications NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch.

fix: lpfc_send_rscn_event sends bigger buffer size lpfc_send_rscn_event() allocates data for sizeof(struct lpfc_rscn_event_header) + payload_len, but claims that the data has size of sizeof(struct lpfc_els_event_header) + payload_len. That leads to buffer overruns.

lpfc: Fix to drop PLOGIs from fabric node till LOGO processing completes The domain controller PLOGI's concurrent with prior LOGO's/unreg_rpi's completing created a race condition where driver rpi ref count can inadvertantly hit 0 and the rpi attempted to be freed. This error sometimes resulted in Warning messages indicating kref.h via lfpc_nlp_get+0x128. Correct by dropping any new PLOGI until the prior nport state has settled.

lpfc: Fix premature release of rpi bit in bitmask Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

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.

Although not a large functional change, as it touches core structures and functions, resulting in a large text delta.
