| * PCI/MSI: Remove bogus warning in pci_irq_get_affinity()Thomas Gleixner2022-02-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent overhaul of pci_irq_get_affinity() introduced a regression when pci_irq_get_affinity() is called for an MSI-X interrupt which was not allocated with affinity descriptor information. The original code just returned a NULL pointer in that case, but the rework added a WARN_ON() under the assumption that the corresponding WARN_ON() in the MSI case can be applied to MSI-X as well. In fact the MSI warning in the original code does not make sense either because it's legitimate to invoke pci_irq_get_affinity() for a MSI interrupt which was not allocated with affinity descriptor information. Remove it and just return NULL as the original code did.

In this case, the following are the two steps in handling those I/O completions: - Call complete() to inform the upper layer handler of completion of the I/O. - Release driver resources associated with the sas_task in pm8001_ccb_task_free() call. When complete() is called, the upper layer may free the sas_task. As such, we should not touch the associated sas_task afterwards, but we do so in the pm8001_ccb_task_free() call. Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.

The abort occurs due to timeout. When the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the sas_task is freed in pm8001_exec_internal_tmf_task(). However, if the I/O completion occurs later, the I/O completion still thinks that the sas_task is available. Fix this by clearing the ccb->task if the TMF times out - the I/O completion handler does nothing if this pointer is cleared.

Martin Wilck reported that it is common for the queue_depth to be subsequently updated in slave_configure() based on detected hardware characteristics. As a result, for some drivers, the static host template settings for cmd_per_lun and can_queue won't actually get used in practice. And if the default values are used to allocate the budget_map, memory may be consumed unnecessarily. Fix the issue by reallocating the budget_map after ->slave_configure() returns. At that time the device queue_depth should accurately reflect what the hardware needs.

However, at the time when any SATA event happens, for almost all the event types, the command is still in the target. It is therefore incorrect to complete the task in sata_event(). There are some events for which we get sata_completions, some need recovery procedure and others abort. All the tasks must be completed via sata_completion() path. Removed the task done related code from sata_events(). For tasks where we don't get completions, let top layer call abort() to abort the command post timeout.

In the connect request, fabrics looks for an existing controller with the same address components and aborts the connect if a controller already exists and the duplicate connect option isn't set. The match routine filters out controllers that are dead or dying, so they don't interfere with the new connect request. When NVME_CTRL_DELETING_NOIO was added, it missed updating the state filters in the nvmf_ctlr_matches_baseopts() routine. Thus, when in this new state, it's seen as a live controller and fails the connect request. Correct by adding the DELETING_NIO state to the match checks.

This may lead to a use-after-free condition that was observed with nvme-tcp. The race condition may happen in the following scenario: 1. driver executes its reset_ctrl_work 2. -> nvme_stop_ctrl - flushes ctrl async_event_work 3. ctrl sends AEN which is received by the host, which in turn schedules AEN handling 4. teardown admin queue (which releases the queue socket) 5. AEN processed, submits another AER, calling the driver to submit 6. driver attempts to send the cmd ==> use-after-free In order to fix that, add ctrl state check to validate the ctrl is actually able to accept the AER submission. This addresses the above race in controller resets because the driver during teardown should: 1. change ctrl state to RESETTING 2. flush async_event_work (as well as other async work elements) So after 1,2, any other AER command will find the ctrl state to be RESETTING and bail out without submitting the AER.

Otherwise the CPU might be faster than the IOMMU hardware and wrongly trigger the WARN_ON() further down the code stream. Use a 10us for udelay(), has there is some hardware where activation of the GA log can take more than a 100ms. A future optimization should move the activation check of the GA log to the point where it gets used for the first time. But that is a bigger change and not suitable for a fix.

The test whether crng_finalize_init() is still required can be moved to the relevant caller in crng_reseed(), and crng_need_final_init can be reset to false if crng_finalize_init() is called with workqueues ready. Then, no previous callsite will call crng_finalize_init() unless it is needed, and we can get rid of the superfluous function parameter.

However, the RNDZAPENTCNT/RNDCLEARPOOL ioctl sets the entropy count to zero -- a potential reduction just like account() -- but does not unblock writers. This commit adds the missing logic to that ioctl to unblock waiting writers. Reviewed-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
