2017-09-27ipmi: Make ipmi_demangle_device_id more genericJeremy Kerr
Currently, ipmi_demagle_device_id requires a full response buffer in its data argument. This means we can't use it to parse a response in a struct ipmi_recv_msg, which has the netfn and cmd as separate bytes. This change alters the definition and users of ipmi_demangle_device_id to use a split netfn, cmd and data buffer, so it can be used with non-sequential responses. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Fixed the ipmi_ssif.c and ipmi_si_intf.c changes to use data from the response, not the data from the message, when passing info to the ipmi_demangle_device_id() function.

2017-09-27ipmi: Add a reference from BMC devices to their interfacesJeremy Kerr

2017-09-25nvme-fcloop: fix port deletes and callbacksJames Smart
Now that there are potentially long delays between when a remoteport or targetport delete calls is made and when the callback occurs (dev_loss_tmo timeout), no longer block in the delete routines and move the final nport puts to the callbacks. Moved the fcloop_nport_get/put/free routines to avoid forward declarations. Ensure port_info structs used in registrations are nulled in case fields are not set (ex: devloss_tmo values).

2017-09-25nvme: allow timed-out ios to retryJames Smart
Currently the nvme_req_needs_retry() applies several checks to see if a retry is allowed. On of those is whether the current time has exceeded the start time of the io plus the timeout length. This check, if an io times out, means there is never a retry allowed for the io. Which means applications see the io failure. Remove this check and allow the io to timeout, like it does on other protocols, and retries to be made. On the FC transport, a frame can be lost for an individual io, and there may be no other errors that escalate for the connection/association. The io will timeout, which causes the transport to escalate into creating a new association, but the io that timed out, due to this retry logic, has already failed back to the application and things are hosed.

2017-09-25nvme: stop aer posting if controller state not liveJames Smart
If an nvme async_event command completes, in most cases, a new async event is posted. However, if the controller enters a resetting or reconnecting state, there is nothing to block the scheduled work element from posting the async event again. Nor are there calls from the transport to stop async events when an association dies. In the case of FC, where the association is torn down, the aer must be aborted on the FC link and completes through the normal job completion path. Thus the terminated async event ends up being rescheduled even though the controller isn't in a valid state for the aer, and the reposting gets the transport into a partially torn down data structure. It's possible to hit the scenario on rdma, although much less likely due to an aer completing right as the association is terminated and as the association teardown reclaims the blk requests via nvme_cancel_request() so its immediate, not a link-related action like on FC. Fix by putting controller state checks in both the async event completion routine where it schedules the async event and in the async event work routine before it calls into the transport. It's effectively a "stop_async_events()" behavior. The transport, when it creates a new association with the subsystem will transition the state back to live and is already restarting the async event posting.

In testing we noticed that nbd would spew if you ran a fio job against the raw device itself. This is because fio calls a block device specific ioctl, however the block layer will first pass this back to the driver ioctl handler in case the driver wants to do something special. Since the device was setup using netlink this caused us to spew every time fio called this ioctl. Since we don't have special handling, just error out for any non-nbd specific ioctl's that come in.

2017-09-23tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic driversHamza Attak
The patch simply replaces all msleep function calls with usleep_range calls in the generic drivers. Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a thousand PCR extends, we see results going from 1m57s unpatched to 40s with the new patch. We obtain similar results when using the original and patched tpm_infineon driver, which is also part of the patch. Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per extend unpatched and around 7ms with the new patch. Note that the PCR consistency is untouched with this patch, each TPM has been tested with 10 million extends and the aggregated PCR value is continuously verified to be correct. As an extension of this work, this could potentially and easily be applied to other vendor's drivers. Still, these changes are not included in the proposed patch as they are untested.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI fixes from Rafael Wysocki: "These fix the initialization of resources in the ACPI WDAT watchdog driver, a recent regression in the ACPI device properties handling, a recent change in behavior causing the ACPI_HANDLE() macro to only work for GPL code and create a MAINTAINERS entry for ACPI PMIC drivers in order to specify the official reviewers for that code. Specifics: - Fix the initialization of resources in the ACPI WDAT watchdog driver that uses unititialized memory which causes compiler warnings to be triggered (Arnd Bergmann). - Fix a recent regression in the ACPI device properties handling that causes some device properties data to be skipped during enumeration (Sakari Ailus). - Fix a recent change in behavior that caused the ACPI_HANDLE() macro to stop working for non-GPL code which is a problem for the NVidia binary graphics driver, for example (John Hubbard). - Add a MAINTAINERS entry for the ACPI PMIC drivers to specify the official reviewers for that code (Rafael Wysocki)" * tag 'acpi-4.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: properties: Return _DSD hierarchical extension (data) sub-nodes correctly ACPI / bus: Make ACPI_HANDLE() work for non-GPL code again ACPI / watchdog: properly initialize resources ACPI / PMIC: Add code reviewers to MAINTAINERS
