2020-03-31of: some unittest overlays not untrackedFrank Rowand
kernel test robot reported "WARNING: held lock freed!" triggered by unittest_gpio_remove(), which should not have been called because the related gpio overlay was not tracked. Another overlay that was tracked had previously used the same id as the gpio overlay but had not been untracked when the overlay was removed. Thus the clean up function of_unittest_destroy_tracked_overlays() incorrectly attempted to remove the reused overlay id. Patch contents: - Create tracking related helper functions - Change BUG() to WARN_ON() for overlay id related issues - Add some additional error checking for valid overlay id values - Add the missing overlay untrack - update comment on expectation that overlay ids are assigned in sequence Fixes: 492a22aceb75 ("of: unittest: overlay: Keep track of created overlays") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Frank Rowand <frank.rowand@sony.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>

Currently, kernel shows the below values "persistence_domain":"cpu_cache" "persistence_domain":"memory_controller" "persistence_domain":"unknown" "cpu_cache" indicates no extra instructions is needed to ensure the persistence of data in the pmem media on power failure. "memory_controller" indicates cpu cache flush instructions are required to flush the data.

2020-03-31drm/amd/display: increase HDCP authentication delayBhawanpreet Lakha
[Why] Some displays have an issue where the hdcp chips are initialized after the display has already lit up. This means we can sometimes authentication too early and cause authentication failures. This happens when HDCP is enabled and the display is power cycled. Normally we will authenticate 2 seconds after the display is lit, but some displays need a bit more time.

2020-03-31PCI: pciehp: Fix MSI interrupt raceStuart Hayes
Without this commit, a PCIe hotplug port can stop generating interrupts on hotplug events, so device adds and removals will not be seen: The pciehp interrupt handler pciehp_isr() reads the Slot Status register and then writes back to it to clear the bits that caused the interrupt. If a different interrupt event bit gets set between the read and the write, pciehp_isr() returns without having cleared all of the interrupt event bits. If this happens when the MSI isn't masked (which by default it isn't in handle_edge_irq(), and which it will never be when MSI per-vector masking is not supported), we won't get any more hotplug interrupts from that device. That is expected behavior, according to the PCIe Base Spec r5.0, section 6.7.3.4, "Software Notification of Hot-Plug Events". Because the Presence Detect Changed and Data Link Layer State Changed event bits can both get set at nearly the same time when a device is added or removed, this is more likely to happen than it might seem. The issue was found (and can be reproduced rather easily) by connecting and disconnecting an NVMe storage device on at least one system model where the NVMe devices were being connected to an AMD PCIe port (PCI device 0x1022/0x1483). Fix the issue by modifying pciehp_isr() to loop back and re-read the Slot Status register immediately after writing to it, until it sees that all of the event status bits have been cleared.

2020-03-31PCI: pciehp: Fix indefinite wait on sysfs requestsLukas Wunner
David Hoyer reports that powering pciehp slots up or down via sysfs may hang: The call to wait_event() in pciehp_sysfs_enable_slot() and _disable_slot() does not return because ctrl->ist_running remains true. This flag, which was introduced by commit 157c1062fcd8 ("PCI: pciehp: Avoid returning prematurely from sysfs requests"), signifies that the IRQ thread pciehp_ist() is running. It is set to true at the top of pciehp_ist() and reset to false at the end. However there are two additional return statements in pciehp_ist() before which the commit neglected to reset the flag to false and wake up waiters for the flag. That omission opens up the following race when powering up the slot: * pciehp_ist() runs because a PCI_EXP_SLTSTA_PDC event was requested by pciehp_sysfs_enable_slot() * pciehp_ist() turns on slot power via the following call stack: pciehp_handle_presence_or_link_change() -> pciehp_enable_slot() -> __pciehp_enable_slot() -> board_added() -> pciehp_power_on_slot() * after slot power is turned on, the link comes up, resulting in a PCI_EXP_SLTSTA_DLLSC event * the IRQ handler pciehp_isr() stores the event in ctrl->pending_events and returns IRQ_WAKE_THREAD * the IRQ thread is already woken (it's bringing up the slot), but the genirq code remembers to re-run the IRQ thread after it has finished (such that it can deal with the new event) by setting IRQTF_RUNTHREAD via __handle_irq_event_percpu() -> __irq_wake_thread() * the IRQ thread removes PCI_EXP_SLTSTA_DLLSC from ctrl->pending_events via board_added() -> pciehp_check_link_status() in order to deal with presence and link flaps per commit 6c35a1ac3da6 ("PCI: pciehp: Tolerate initially unstable link") * after pciehp_ist() has successfully brought up the slot, it resets ctrl->ist_running to false and wakes up the sysfs requester * the genirq code re-runs pciehp_ist(), which sets ctrl->ist_running to true but then returns with IRQ_NONE because ctrl->pending_events is empty * pciehp_sysfs_enable_slot() is finally woken but notices that ctrl->ist_running is true, hence continues waiting The only way to get the hung task going again is to trigger a hotplug event which brings down the slot, e.g. by yanking out the card. The same race exists when powering down the slot because remove_board() likewise clears link or presence changes in ctrl->pending_events per commit 3943af9d01e9 ("PCI: pciehp: Ignore Link State Changes after powering off a slot") and thereby may cause a re-run of pciehp_ist() which returns with IRQ_NONE without resetting ctrl->ist_running to false. Fix by adding a goto label before the teardown steps at the end of pciehp_ist() and jumping to that label from the two return statements which currently neglect to reset the ctrl->ist_running flag.

2020-03-31of: of_private.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-31nvme: fix compat address handling in several ioctlsNick Bowler
On a 32-bit kernel, the upper bits of userspace addresses passed via various ioctls are silently ignored by the nvme driver. However on a 64-bit kernel running a compat task, these upper bits are not ignored and are in fact required to be zero for the ioctls to work. Unfortunately, this difference matters. 32-bit smartctl submits the NVME_IOCTL_ADMIN_CMD ioctl with garbage in these upper bits because it seems the pointer value it puts into the nvme_passthru_cmd structure is sign extended. This works fine on 32-bit kernels but fails on a 64-bit one because (at least on my setup) the addresses smartctl uses are consistently above 2G. For example: # smartctl -x /dev/nvme0n1 smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.5.11] (local build) Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org Read NVMe Identify Controller failed: NVME_IOCTL_ADMIN_CMD: Bad address Since changing 32-bit kernels to actually check all of the submitted address bits now would break existing userspace, this patch fixes the compat problem by explicitly zeroing the upper bits in the compat case. This enables 32-bit smartctl to work on a 64-bit kernel. Signed-off-by: Nick Bowler <nbowler@draconx.ca> Signed-off-by: Christoph Hellwig <hch@lst.de>
