2020-07-28Bluetooth: btusb: Fix and detect most of the Chinese Bluetooth controllersIsmael Ferreras Morezuelas
For some reason they tend to squat on the very first CSR/ Cambridge Silicon Radio VID/PID instead of paying fees. This is an extremely common problem; the issue goes as back as 2013 and these devices are only getting more popular, even rebranded by reputable vendors and sold by retailers everywhere. So, at this point in time there are hundreds of modern dongles reusing the ID of what originally was an early Bluetooth 1.1 controller. Linux is the only place where they don't work due to spotty checks in our detection code. It only covered a minimum subset. So what's the big idea? Take advantage of the fact that all CSR chips report the same internal version as both the LMP sub-version and HCI revision number. It always matches, couple that with the manufacturer code, that rarely lies, and we now have a good idea of who is who. Additionally, by compiling a list of user-reported HCI/lsusb dumps, and searching around for legit CSR dongles in similar product ranges we can find what CSR BlueCore firmware supported which Bluetooth versions. That way we can narrow down ranges of fakes for each of them. e.g. Real CSR dongles with LMP subversion 0x73 are old enough that support BT 1.1 only; so it's a dead giveaway when some third-party BT 4.0 dongle reuses it. So, to sum things up; there are multiple classes of fake controllers reusing the same 0A12:0001 VID/PID. This has been broken for a while.

2020-07-27clk: tegra: pll: Improve PLLM enable-state detectionDmitry Osipenko
Power Management Controller (PMC) can override the PLLM clock settings, including the enable-state. Although PMC could only act as a second level gate, meaning that PLLM needs to be enabled by the Clock and Reset Controller (CaR) anyways if we want it to be enabled. Hence, when PLLM is overridden by PMC, it needs to be enabled by CaR and ungated by PMC in order to be functional. Please note that this patch doesn't fix any known problem, and thus, it's merely a minor improvement.

This pin is also used to wake the machine when a WoL packet is received by the PHY. The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU), and other models. Without it, the board remains forever halted if a power off command is executed, unless the PSU is disconnected and connected again.

2020-07-27drm: hold gem reference until object is no longer accessedSteve Cohen
A use-after-free in drm_gem_open_ioctl can happen if the GEM object handle is closed between the idr lookup and retrieving the size from said object since a local reference is not being held at that point. Hold the local reference while the object can still be accessed to fix this and plug the potential security hole.

2020-07-27qed: fix assignment of n_rq_elems to incorrect params fieldColin Ian King
Currently n_rq_elems is being assigned to params.elem_size instead of the field params.num_elems. Coverity is detecting this as a double assingment to params.elem_size and reporting this as an usused value on the first assignment. Fix this.

This patch refactors the vfio_iommu_type1_ioctl() to use switch instead of if-else, and each command got a helper function.

2020-07-27vfio/pci: Add QAT devices to denylistGiovanni Cabiddu
The current generation of Intel® QuickAssist Technology devices are not designed to run in an untrusted environment because of the following issues reported in the document "Intel® QuickAssist Technology (Intel® QAT) Software for Linux" (document number 336211-014): QATE-39220 - GEN - Intel® QAT API submissions with bad addresses that trigger DMA to invalid or unmapped addresses can cause a platform hang QATE-7495 - GEN - An incorrectly formatted request to Intel® QAT can hang the entire Intel® QAT Endpoint The document is downloadable from https://01.org/intel-quickassist-technology at the following link: https://01.org/sites/default/files/downloads/336211-014-qatforlinux-releasenotes-hwv1.7_0.pdf This patch adds the following QAT devices to the denylist: DH895XCC, C3XXX and C62X.

2020-07-27vfio/pci: Add device denylistGiovanni Cabiddu
Add denylist of devices that by default are not probed by vfio-pci. Devices in this list may be susceptible to untrusted application, even if the IOMMU is enabled. To be accessed via vfio-pci, the user has to explicitly disable the denylist. The denylist can be disabled via the module parameter disable_denylist.

2020-07-27vfio/spapr_tce: convert get_user_pages() --> pin_user_pages()John Hubbard
This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages*() + put_page() calls to pin_user_pages*() + unpin_user_pages() calls. There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

2020-07-27vfio/pci: Add Intel X550 to hidden INTx devicesAlex Williamson
Intel document 333717-008, "Intel® Ethernet Controller X550 Specification Update", version 2.7, dated June 2020, includes errata #22, added in version 2.1, May 2016, indicating X550 NICs suffer from the same implementation deficiency as the 700-series NICs: "The Interrupt Status bit in the Status register of the PCIe configuration space is not implemented and is not set as described in the PCIe specification." Without the interrupt status bit, vfio-pci cannot determine when these devices signal INTx. They are therefore added to the nointx quirk.
