This patch updates ACQE handling for: - an EEPROM failure error reported by the adapter. - ensures that all data for any ACQE, recognized or not, is logged. - Given that all data is now logged unconditionally, the default case (unrecognized) data can be reduced.

In lpfc_release_io_buf, an lpfc_io_buf is returned to the 'available' pool before any associated sgl or cmd and rsp buffers are returned via their respective 'put' routines. If xri rebalancing occurs and an lpfc_io_buf structure is reused quickly, there may be a race condition between release of old and association of new resources. Re-ordered lpfc_release_io_buf to release sgl and cmd/rsp buffer lists before releasing the lpfc_io_buf structure for re-use.

Many of the sgl-per-hdwq paths are locking with spin_lock_irq() and spin_unlock_irq() and may unwittingly raising irq when it shouldn't. Hard deadlocks were seen around lpfc_scsi_prep_cmnd(). Fix by converting the locks to irqsave/irqrestore. Fixes: d79c9e9d ("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")

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 Given this change, the recognition of "driver-generated" status which then releases the iocb is no longer valid.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 29601228 is reverted. As recognition of "driver-generated" status is no longer valid, this patch reverts the changes made in commit 29601228 ("scsi: lpfc: Fix leak of ELS completions on adapter reset") - Modify lpfc_work_done to allow slow path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. Link: https://lore.kernel.org/r/20190922035906.10977-14-jsmart2021@gmail.comSigned-off-by:

Scenarios were seen where a host hung when the system booted or the host was very slow in booting. The link would not come up and no luns were visible to the host. After investigation, this was found to be due to the introduction of a new ACQE that adapter may generate to report a adapter hw warning. The ACQE was delivered to the driver very early in adapter initialization, when the driver did not expect command completion. As part of handling this unexpected interrupt the an EQEs are consumed and discarded and the EQ rearmed. The issue is the CQ that cause the EQE and thus the interrupt was not processed and the CQ was left unarmed. Meaning it would no longer generate a new interrupt condition. Subsequent mailbox commands used to initialize the adapter use the same CQ, and as there was no completion interrupt generated, the driver never saw the mailbox commands complete and it would wait long command timeouts. Fix by having the early flush routine also process the related CQ and rearm the CQ. Link: https://lore.kernel.org/r/20190922035906.10977-13-jsmart2021@gmail.comSigned-off-by:

When the port, running as a nvme target, receives an ABTS, it submits commands to the adapter to Abort i/o outstanding in the adapter. The Abort command formatting routine left a command field set to zero, which instructs the adapter to generate an ABTS on the wire as part of cleaning up the I/O. This is common operation for an initiator, but not for a target. Fix the driver to check whether an ABTS had been received for the I/O, and if so, change the Abort command formatting so that the ABTS generation is disabled (IA=1). No need to ABTS it when the other side already has. Also refactored the code such that there is a single routine being used for nvme or nvmet ABORT requests, and IA is an argument.

An issue was seen discovering all SCSI Luns when a target device undergoes link bounce. The driver currently does not qualify the FC4 support on the target. Therefore it will send a SCSI PRLI and an NVMe PRLI. The expectation is that the target will reject the PRLI if it is not supported. If a PRLI times out, the driver will retry. The driver will not proceed with the device until both SCSI and NVMe PRLIs are resolved. In the failure case, the device is FCP only and does not respond to the NVMe PRLI, thus initiating the wait/retry loop in the driver. During that time, a RSCN is received (device bounced) causing the driver to issue a GID_FT. The GID_FT response comes back before the PRLI mess is resolved and it prematurely cancels the PRLI retry logic and leaves the device in a STE_PRLI_ISSUE state. Discovery with the target never completes or resets. Fix by resetting the node state back to STE_NPR_NODE when GID_FT completes, thereby restarting the discovery process for the node.

Faults are seen with RIP of lpfc_scsi_cmd_iocb_cmpl(). The failure is when lpfc_update_status is being called as part of the completion. After debugging, it was seen the issue was the shost pointer that the driver derived from the scsi cmd. The crash showed the cmd->device pointer being bogus, which is likely as the scsi devices were offlined prior. The bogus device pointer caused subsequent pointers derived from the location, specifically the vport, to be bogus. Fix by adjusting the calling sequence to pass in the vport rather than having to derive it from the cmd structure.

Symptoms were seen of the driver not having valid data for mailbox commands. After debugging, the following sequence was found: The driver maintains a port-wide pointer of the mailbox command that is currently in execution. Once finished, the port-wide pointer is cleared (done in lpfc_sli4_mq_release()). The next mailbox command issued will set the next pointer and so on. The mailbox response data is only copied if there is a valid port-wide pointer. In the failing case, it was seen that a new mailbox command was being attempted in parallel with the completion. The parallel path was seeing the mailbox no long in use (flag check under lock) and thus set the port pointer. The completion path had cleared the active flag under lock, but had not touched the port pointer. The port pointer is cleared after the lock is released. In this case, the completion path cleared the just-set value by the parallel path. Fix by making the calls that clear mbox state/port pointer while under lock. Also slightly cleaned up the error path. Link: https://lore.kernel.org/r/20190922035906.10977-8-jsmart2021@gmail.comSigned-off-by:

When target-side fault injections are made, the driver isn't reconnecting to the remote port. The driver is logging "2753" error messages which state: "PLOGI failure DID:1B2400 Status:x3/xf0240008" The failures status is indicating a Illegal field error, which points to the Temporary RPI field being used for the ELS. This error typically means the driver used an RPI that was already registered (shouldn't be registered if using it in this context). Study has found that if the driver were in discovery attempts and encountered an error, it wouldn't flag the temporary rpi in error. Yet the rpi was released for reallocation in these error paths and another ELS could allocate the rpi. In the failure situation a retry was done on an ELS that had encountered an error, and as the rpi wasn't marked in error, the ELS reused the rpi it originally allocated. But that rpi had been allocated by a different ELS issued after the original error and before the retry attempt. The different ELS had succeeded and the RPI was registered. Fix by marking the rpi state for the node to be in error, aka as needing reallocation, upon an error in the els processing. Error state marking is always done prior to release back to the internal rpi free list, which the driver wasn't doing in cases prior. Also enhanced some of the logging to help in the next case of problem troubleshooting. Link: https://lore.kernel.org/r/20190922035906.10977-7-jsmart2021@gmail.comSigned-off-by:

A prior use-after-free mailbox fix solved it's problem by null'ing a ndlp pointer. However, further testing has shown that this change causes a later state change to occasionally be skipped, which results in a reference count never being decremented thus the rpi is never released, which causes a vport delete to never succeed. Revise the fix in the prior patch to no longer null the ndlp. Instead the RELEASE_RPI flag is set which will drive the release of the rpi. Given the new code was added at a deep indentation level, refactor the code block using a new routine that avoids the indentation issues. Fixes: 9b164068 ("scsi: lpfc: Fix use-after-free mailbox cmd completion") Link: https://lore.kernel.org/r/20190922035906.10977-6-jsmart2021@gmail.comSigned-off-by:

The nvme-fc transport may call to abort an io on controller reset. If the driver is out of resources to issue an abort command, it just gives up and does nothing. The transport expects the lldd to always be able to terminate an io it has issued. At that point, the controller hangs waiting for aborted ios to be returned. Note: flaged by "6136" and "6176" error messages. Root issue was the adapter mis-allocated the number resources it allocated for command entries for the adapter. Convert the driver to allocate command resources based on the number of xris supported by the FC port - 1 resource for the original command and 1 resource for the abort request.

After exchanging PLOGI on an SLI-3 adapter, the PRLI exchange failed. Link trace showed the port was assigned a non-zero n_port_id, but didn't use the address on the PRLI. The assigned address is set on the port by the CONFIG_LINK mailbox command. The driver responded to the PRLI before the mailbox command completed. Thus the PRLI response used the old n_port_id. Defer the PRLI response until CONFIG_LINK completes. Link: https://lore.kernel.org/r/20190922035906.10977-2-jsmart2021@gmail.comSigned-off-by:

Merge active entropy generation updates. This is admittedly partly "for discussion". We need to have a way forward for the boot time deadlocks where user space ends up waiting for more entropy, but no entropy is forthcoming because the system is entirely idle just waiting for something to happen. While this was triggered by what is arguably a user space bug with GDM/gnome-session asking for secure randomness during early boot, when they didn't even need any such truly secure thing, the issue ends up being that our "getrandom()" interface is prone to that kind of confusion, because people don't think very hard about whether they want to block for sufficient amounts of entropy. The approach here-in is to decide to not just passively wait for entropy to happen, but to start actively collecting it if it is missing. This is not necessarily always possible, but if the architecture has a CPU cycle counter, there is a fair amount of noise in the exact timings of reasonably complex loads. We may end up tweaking the load and the entropy estimates, but this should be at least a reasonable starting point. As part of this, we also revert the revert of the ext4 IO pattern improvement that ended up triggering the reported lack of external entropy. * getrandom() active entropy waiting: Revert "Revert "ext4: make __ext4_get_inode_loc plug"" random: try to actively add entropy rather than passively wait for it

This reverts commit 72dbcf72. Instead of waiting forever for entropy that may just not happen, we now try to actively generate entropy when required, and are thus hopefully avoiding the problem that caused the nice ext4 IO pattern fix to be reverted.

For 5.3 we had to revert a nice ext4 IO pattern improvement, because it caused a bootup regression due to lack of entropy at bootup together with arguably broken user space that was asking for secure random numbers when it really didn't need to. See commit 72dbcf72 (Revert "ext4: make __ext4_get_inode_loc plug"). This aims to solve the issue by actively generating entropy noise using the CPU cycle counter when waiting for the random number generator to initialize. This only works when you have a high-frequency time stamp counter available, but that's the case on all modern x86 CPU's, and on most other modern CPU's too. What we do is to generate jitter entropy from the CPU cycle counter under a somewhat complex load: calling the scheduler while also guaranteeing a certain amount of timing noise by also triggering a timer. I'm sure we can tweak this, and that people will want to look at other alternatives, but there's been a number of papers written on jitter entropy, and this should really be fairly conservative by crediting one bit of entropy for every timer-induced jump in the cycle counter. Not because the timer itself would be all that unpredictable, but because the interaction between the timer and the loop is going to be. Even if (and perhaps particularly if) the timer actually happens on another CPU, the cacheline interaction between the loop that reads the cycle counter and the timer itself firing is going to add perturbations to the cycle counter values that get mixed into the entropy pool. As Thomas pointed out, with a modern out-of-order CPU, even quite simple loops show a fair amount of hard-to-predict timing variability even in the absense of external interrupts. But this tries to take that further by actually having a fairly complex interaction. This is not going to solve the entropy issue for architectures that have no CPU cycle counter, but it's not clear how (and if) that is solvable, and the hardware in question is largely starting to be irrelevant. And by doing this we can at least avoid some of the even more contentious approaches (like making the entropy waiting time out in order to avoid the possibly unbounded waiting).

Pull thermal SoC updates from Eduardo Valentin: "This is a really small pull in the midst of a lot of pending patches. We are in the middle of restructuring how we are maintaining the thermal subsystem, as per discussion in our last LPC. For now, I am sending just some changes that were pending in my tree. Looking forward to get a more streamlined process in the next merge window" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal: thermal: db8500: Rewrite to be a pure OF sensor thermal: db8500: Use dev helper variable thermal: db8500: Finalize device tree conversion thermal: thermal_mmio: remove some dead code

Pull iommu fixes from Joerg Roedel: "A couple of fixes for the AMD IOMMU driver have piled up: - Some fixes for the reworked IO page-table which caused memory leaks or did not allow to downgrade mappings under some conditions. - Locking fixes to fix a couple of possible races around accessing 'struct protection_domain'. The races got introduced when the dma-ops path became lock-less in the fast-path" * tag 'iommu-fixes-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Lock code paths traversing protection_domain->dev_list iommu/amd: Lock dev_data in attach/detach code paths iommu/amd: Check for busy devices earlier in attach_device() iommu/amd: Take domain->lock for complete attach/detach path iommu/amd: Remove amd_iommu_devtable_lock iommu/amd: Remove domain->updated iommu/amd: Wait for completion of IOTLB flush in attach_device iommu/amd: Unmap all L7 PTEs when downgrading page-sizes iommu/amd: Introduce first_pte_l7() helper iommu/amd: Fix downgrading default page-sizes in alloc_pte() iommu/amd: Fix pages leak in free_pagetable()
