If logout response is not received and ->ep_disconnect() is called then close tcp conn by RST instead of FIN to cleanup conn resources immediately. Also move ->csk_push_tx_frames() above 'done:' to avoid calling ->csk_push_tx_frames() in error cases. Signed-off-by:

Hung task timeouts can result if a qlogic board breaks unexpectedly while running I/O. These tasks become hung because command srb reference counts are not going to zero, hence the affected srbs and commands do not get freed. This fix accounts for this extra reference in the srbs in the case of a board failure.

We might have a NULL pring in lpfc_els_abort(), for example on error recovery path, since queues are destroyed during error recovery mechanism. In this case, we should just drop the abort since the queues will be recreated anyway. This patch just verifies for NULL pointer and stop the abortion of the queue in case of a NULL pring. Also, this patch converts return type of lpfc_els_abort() from int to void, since it's not checked anywhere. Reported-by:

The lpfc_nvmeio_data() tracing helper always takes a format string and three additional arguments. The latest caller has a format string with only two integer arguments, causing this harmless warning: drivers/scsi/lpfc/lpfc_nvmet.c: In function 'lpfc_nvmet_xmt_fcp_release': drivers/scsi/lpfc/lpfc_nvmet.c:802:25: error: too many arguments for format [-Werror=format-extra-args] lpfc_nvmeio_data(phba, "NVMET FCP FREE: xri x%x ste %d\n", ctxp->oxid, We could add a dummy argument here, but it seems reasonable to print the 'abort' flag as the third argument.

when driver is loaded with Multi Queue enabled, it was noticed that there was one less queue pair created. Following message would indicate this: "No resources to create additional q pair." The result of one less queue pair means that system can crash, if the block mq layer thinks there is an extra hardware queue available, and the driver will use a NULL ptr qpair in that instance.

When pci_enable_device() or pci_enable_device_mem() fail in qla2x00_probe_one() we bail out but do a call to pci_disable_device(). This causes the dev_WARN_ON() in pci_disable_device() to trigger, as the device wasn't enabled previously. So instead of taking the 'probe_out' error path we can directly return *iff* one of the pci_enable_device() calls fails. Additionally rename the 'probe_out' goto label's name to the more descriptive 'disable_device'. Signed-off-by:

munmap done by iscsiuio during a stop of the service triggers a "bad pte" warning sometimes. munmap kernel path goes through the mmapped pages and has a validation check for mapcount (in struct page) to be zero or above. kzalloc, which we had used to allocate udev->ctrl, uses slab allocations, which re-uses mapcount (union) for other purposes that can make the mapcount look negative. Avoid all these trouble by invoking one of the __get_free_pages wrappers to be used instead of kzalloc for udev->ctrl.

Long Li authored
In lower layer driver's (LLD) scsi_host_template, the driver may optionally ask SCSI to allocate its private driver memory for each command, by specifying cmd_size. This memory is allocated at the end of scsi_cmnd by SCSI. Later when SCSI queues a command, the LLD can use scsi_cmd_priv to get to its private data. Some LLD, e.g. hv_storvsc, doesn't clear its private data before use. In this case, the LLD may get to stale or uninitialized data in its private driver memory. This may result in unexpected driver and hardware behavior. Fix this problem by also zeroing the private driver memory before passing them to LLD. Signed-off-by:

Recent commit on patchset "lpfc updates for 11.2.0.14" fixed an issue about dereferencing a NULL pointer on port reset. The specific commit, named "lpfc: Fix system crash when port is reset.", is missing a check against NULL pointer on lpfc_els_flush_cmd() though. Since we destroy the queues on adapter resets, like in PCI error recovery path, we need the validation present on this patch in order to avoid a NULL pointer dereference when trying to flush commands of ELS wq, after it has been destroyed (which would lead to a kernel oops).

Code review of NVMEI's FC_PORT_ROLE_NVME_DISCOVERY looked wrong. Discussions with storage architecture team clarified NVMEI's audit of the PRLI response port roles. Following up discussion with code review showed a few minor corrections were required - especially in anticipation of NVME auto discovery. During PRLI, NVMEI should sent prli_init - which it it does. NVMET should send prli_tgt and prli_disc - which it does. When NVMEI receives a PRLI Response now, it audits the incoming target bits and stores the attributes in the corresponding NDLP. Later, when NVMEI registers the NVME rport, it uses the stored ndlp attributes to set the rport port_roles correctly. Signed-off-by:

Too many work items being processed in IRQ context take a lot of CPU time and cause problems. With a recent change, we get out of the ISR after hitting entry_repost work items on a queue. However, the actual values for entry repost are still high. EQ is 128 and CQ is 128, this could translate into processing 128 * 128 (16384) work items under IRQ context. Set entry_repost in the actual queue creation routine now. Limit EQ repost to 8 and CQ repost to 64 to further limit the amount of time spent in the IRQ. Fix fof IRQ routines as well. Signed-off-by:

When unloading and reloading the driver, the driver fails to recreate the lpfc root inode in the debugfs tree. The driver is incorrectly removing the lpfc root inode in lpfc_debugfs_terminate in the first driver instance that unloads and then sets the lpfc_debugfs_root global parameter to NULL. When the final driver instance unloads, the debugfs calls quietly ignore the remove on a NULL pointer. The bug is that the debugfs_remove call returns void so the driver doesn't know to correctly set the global parameter to NULL. Base the debugfs_remove of the lpfc_debugfs_root parameter on lpfc_debugfs_hba_count because this parameter tracks the fnX instance tracked per driver instance. Signed-off-by:

Currently IO resources are mapped 1 to 1 with RQ buffers posted Added logic to separate RQE buffers from IO op resources (sgl/iocbq/context). During initialization, the driver will determine how many SGLs it will allocate for NVMET (based on what the firmware reports) and associate a NVMET IOCBq and NVMET context structure with each one. Now that hdr/data buffers are immediately reposted back to the RQ, 512 RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now 128 bytes, lpfc_nvmet_mrq_post is not necessary anymore as we will always post the max (512) buffers per NVMET MRQ. Signed-off-by:
