drm/tegra: Changes for v4.16-rc1
The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAlpXlPQTHHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zoUFKD/4vXdkmMUkWjZM0xrdwsPi6DvQe3uBa tE4wchelVnNvLJfBnMVJyEPDiNLoq12pJ6Ol8LRX2f5ExnQUwIEd+RSQPgWSUP6+ bITqSAb9LnEEHMfYLXTHFoBSeqV9nGvpYcouupW5R4cdV4/T7k7x1/6QQg6Byoyx TULTcpCmMFX4FQGrqWHSrPrkw+MDWYiDmekYcrHmrgOtZUfG7DxdWtQpgs2lrstg m+FZADSVJ9CwuVgwAO4VTDIeKVHW54b5UPYseH1u/uaAoxVPC50XNJk3RLuSPVWg 8d6BpkUoqmWq8w5tmR+/zx0/WobyRAQYljdd1kWFnnn3slNOvVV6bnOSo9u3OatZ 1DGyaeQr9hXQ2CdSx2oImex2Kslb14yJPczFa6GQBfrfPOPKJk8eh1GIF6bWGtQa +hzWr1BDDd/q2x6jkIFMQel33Z8dNy1+22GcSYpuofuQeMqD4msccfhnTce1/Mhy h0+fQK2eFWDbtvSj6rao4CtzVDOCi9+b93Hva/kh7Ap2Wn7eUDLmRh/VtnUj7EP7 LYPNYlFC6rWzfTdHV0oYUizXNRx6ZzQFNYXNmRjjfVMzrXeqkpSsZXcYVhd4J3PB EmZpiWNeqqGUnoxvSUX0AmC3/VSi7dU+E8ecIzyeVMry2cgXSal7gewPirDUICOI uiYCJaeWxHJBAA== =FfXI -----END PGP SIGNATURE----- Merge tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186.

uapi/if_ether.h: prevent redefinition of struct ethhdr
Musl provides its own ethhdr struct definition. Add a guard to prevent its definition of the appropriate musl header has already been included. glibc does not implement this header, but when glibc will implement this they can just define __UAPI_DEF_ETHHDR 0 to make it work with the kernel.

uapi libc compat: add fallback for unsupported libcs
libc-compat.h aims to prevent symbol collisions between uapi and libc headers for each supported libc. This requires continuous coordination between them. The goal of this commit is to improve the situation for libcs (such as musl) which are not yet supported and/or do not wish to be explicitly supported, while not affecting supported libcs. More precisely, with this commit, unsupported libcs can request the suppression of any specific uapi definition by defining the correspondings _UAPI_DEF_* macro as 0. This can fix symbol collisions for them, as long as the libc headers are included before the uapi headers. Inclusion in the other order is outside the scope of this commit. All infrastructure in order to enable this fallback for unsupported libcs is already in place, except that libc-compat.h unconditionally defines all _UAPI_DEF_* macros to 1 for all unsupported libcs so that any previous definitions are ignored. In order to fix this, this commit merely makes these definitions conditional. This commit together with the musl libc commit http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258 fixes for example the following compiler errors when <linux/in6.h> is included after musl's <netinet/in.h>: ./linux/in6.h:32:8: error: redefinition of 'struct in6_addr' ./linux/in6.h:49:8: error: redefinition of 'struct sockaddr_in6' ./linux/in6.h:59:8: error: redefinition of 'struct ipv6_mreq' The comments referencing glibc are still correct, but this file is not only used for glibc any more.

drm/exynos: ipp: Remove Exynos DRM IPP subsystem
Exynos DRM IPP subsystem is in fact non-functional and frankly speaking dead-code. This patch clearly marks that Exynos DRM IPP subsystem is broken and never really functional. It will be replaced by a completely rewritten API. Exynos DRM IPP user-space API can be obsoleted for the following reasons: 1. Exynos DRM IPP user-space API can be optional in Exynos DRM, so userspace should not rely that it is always available and should have a software fallback in case it is not there. 2. The only mode which was initially semi-working was memory-to-memory image processing. The remaining modes (LCD-"writeback" and "output") were never operational due to missing code (both in mainline and even vendor kernels). 3. Exynos DRM IPP mainline user-space API compatibility for memory-to-memory got broken very early by commit |

netfilter: uapi: correct UNTRACKED conntrack state bit number
nft_ct exposes this bit to userspace. This used to be
#define NF_CT_STATE_UNTRACKED_BIT (1 << (IP_CT_NUMBER + 1))
(IP_CT_NUMBER is 5, so this was 0x40)
.. but this got changed to 8 (0x100) when the untracked object got removed.
Replace this with a literal 6 to prevent further incompatible changes
in case IP_CT_NUMBER ever increases.

drm/tegra: Sanitize format modifiers
The existing format modifier definitions were merged prematurely, and recent work has unveiled that the definitions are suboptimal in several ways: - The format specifiers, except for one, are not Tegra specific, but the names don't reflect that. - The number space is split into two, reserving 32 bits for some "parameter" which most of the modifiers are not going to have. - Symbolic names for the modifiers are not using the standard DRM_FORMAT_MOD_* prefix, which makes them awkward to use. - The vendor prefix NV is somewhat ambiguous. Fortunately, nobody's started using these modifiers, so we can still fix the above issues. Do so by using the standard prefix. Also, remove TEGRA from the name of those modifiers that exist on NVIDIA GPUs as well. In case of the block linear modifiers, make the "parameter" smaller (4 bits, though only 6 values are valid) and don't let that leak into any of the other modifiers. Finally, also use the more canonical NVIDIA instead of the ambiguous NV prefix. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thierry Reding <treding@nvidia.com> |

USB fixes for 4.15-rc3
Here are a few minor USB fixes for 4.15-rc3. The largest here is the Kconfig text and configuration changes for the USB TypeC build options that you reported during the -rc1 merge window. The others are all just small fixes for reported issues, as well as some new device ids. The most "interesting" of anything here is the usbip fixes as it seems lots of people are starting to pay attention to that driver at the moment. These fixes should resolve all of the reported problems as of now. Of course there are the usual xhci and gadget fixes as well, can't go a pull request without those...

vfio: ABI for mdev display dma-buf operation
Add VFIO_DEVICE_QUERY_GFX_PLANE ioctl command to let user query and get a plane and its information. So far, two types of buffers are supported: buffers based on dma-buf and buffers based on region. This ioctl can be invoked with: 1) Either DMABUF or REGION flag. Vendor driver returns a plane_info successfully only when the specific kind of buffer is supported. 2) Flag PROBE. And at the same time either DMABUF or REGION must be set, so that vendor driver returns success only when the specific kind of buffer is supported. Add VFIO_DEVICE_GET_GFX_DMABUF ioctl command to let user get a specific dma-buf fd of an exposed MDEV buffer provided by dmabuf_id which was returned in VFIO_DEVICE_QUERY_GFX_PLANE ioctl command. The life cycle of an exposed MDEV buffer is handled by userspace and tracked by kernel space. The returned dmabuf_id in struct vfio_device_ query_gfx_plane can be a new id of a new exposed buffer or an old id of a re-exported buffer. Host user can check the value of dmabuf_id to see if it needs to create new resources according to the new exposed buffer or just re-use the existing resource related to the old buffer. v18: - update comments for VFIO_DEVICE_GET_GFX_DMABUF. (Alex) v17: - modify VFIO_DEVICE_GET_GFX_DMABUF interface. (Alex) v16: - add x_hot and y_hot fields. (Gerd) - add comments for VFIO_DEVICE_GET_GFX_DMABUF. (Alex) - rebase to 4.14.0-rc6. v15: - add a ioctl to get a dmabuf for a given dmabuf id. (Gerd) v14: - add PROBE, DMABUF and REGION flags. (Alex) v12: - add drm_format_mod back. (Gerd and Zhenyu) - add region_index. (Gerd) v11: - rename plane_type to drm_plane_type. (Gerd) - move fields of vfio_device_query_gfx_plane to vfio_device_gfx_plane_info. (Gerd) - remove drm_format_mod, start fields. (Daniel) - remove plane_id. v10: - refine the ABI API VFIO_DEVICE_QUERY_GFX_PLANE. (Alex) (Gerd) v3: - add a field gvt_plane_info in the drm_i915_gem_obj structure to save the decoded plane information to avoid look up while need the plane info.

USB: core: Add type-specific length check of BOS descriptors
As most of BOS descriptors are longer in length than their header 'struct usb_dev_cap_header', comparing solely with it is not sufficient to avoid out-of-bounds access to BOS descriptors.

Rename superblock flags (MS_xyz -> SB_xyz)
This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags.

drm/i915/pmu: Aggregate all RC6 states into one counter
Chris has discovered that RC6, RC6p and RC6pp counters are mutually exclusive, and even that on some SNB SKUs you get RC6p increasing, and on the others RC6. Furthermore RC6p and RC6pp were only present starting from GEN6 until, GEN7, not including Haswell. All this combined makes it questionable whether we need to reserve new ABI for these counters. One idea was to just combine them all under the RC6 counter to simplify things for userspace. So that is what this patch does.

rxrpc: Fix call timeouts
Fix the rxrpc call expiration timeouts and make them settable from userspace. By analogy with other rx implementations, there should be three timeouts: (1) "Normal timeout" This is set for all calls and is triggered if we haven't received any packets from the peer in a while. It is measured from the last time we received any packet on that call. This is not reset by any connection packets (such as CHALLENGE/RESPONSE packets). If a service operation takes a long time, the server should generate PING ACKs at a duration that's substantially less than the normal timeout so is to keep both sides alive. This is set at 1/6 of normal timeout. (2) "Idle timeout" This is set only for a service call and is triggered if we stop receiving the DATA packets that comprise the request data. It is measured from the last time we received a DATA packet. (3) "Hard timeout" This can be set for a call and specified the maximum lifetime of that call. It should not be specified by default. Some operations (such as volume transfer) take a long time. Allow userspace to set/change the timeouts on a call with sendmsg, using a control message: RXRPC_SET_CALL_TIMEOUTS The data to the message is a number of 32-bit words, not all of which need be given: u32 hard_timeout; /* sec from first packet */ u32 idle_timeout; /* msec from packet Rx */ u32 normal_timeout; /* msec from data Rx */ This can be set in combination with any other sendmsg() that affects a call.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Daniel Borkmann says: ==================== pull-request: bpf 2017-11-23 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Several BPF offloading fixes, from Jakub. Among others: - Limit offload to cls_bpf and XDP program types only. - Move device validation into the driver and don't make any assumptions about the device in the classifier due to shared blocks semantics. - Don't pass offloaded XDP program into the driver when it should be run in native XDP instead. Offloaded ones are not JITed for the host in such cases. - Don't destroy device offload state when moved to another namespace. - Revert dumping offload info into user space for now, since ifindex alone is not sufficient. This will be redone properly for bpf-next tree. 2) Fix test_verifier to avoid using bpf_probe_write_user() helper in test cases, since it's dumping a warning into kernel log which may confuse users when only running tests. Switch to use bpf_trace_printk() instead, from Yonghong. 3) Several fixes for correcting ARG_CONST_SIZE_OR_ZERO semantics before it becomes uabi, from Gianluca. More specifically: - Add a type ARG_PTR_TO_MEM_OR_NULL that is used only by bpf_csum_diff(), where the argument is either a valid pointer or NULL. The subsequent ARG_CONST_SIZE_OR_ZERO then enforces a valid pointer in case of non-0 size or a valid pointer or NULL in case of size 0. Given that, the semantics for ARG_PTR_TO_MEM in combination with ARG_CONST_SIZE_OR_ZERO are now such that in case of size 0, the pointer must always be valid and cannot be NULL. This fix in semantics allows for bpf_probe_read() to drop the recently added size == 0 check in the helper that would become part of uabi otherwise once released. At the same time we can then fix bpf_probe_read_str() and bpf_perf_event_output() to use ARG_CONST_SIZE_OR_ZERO instead of ARG_CONST_SIZE in order to fix recently reported issues by Arnaldo et al, where LLVM optimizes two boundary checks into a single one for unknown variables where the verifier looses track of the variable bounds and thus rejects valid programs otherwise. 4) A fix for the verifier for the case when it detects comparison of two constants where the branch is guaranteed to not be taken at runtime. Verifier will rightfully prune the exploration of such paths, but we still pass the program to JITs, where they would complain about using reserved fields, etc. Track such dead instructions and sanitize them with mov r0,r0. Rejection is not possible since LLVM may generate them for valid C code and doesn't do as much data flow analysis as verifier. For bpf-next we might implement removal of such dead code and adjust branches instead. Fix from Alexei. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

drm/i915/pmu: Expose a PMU interface for perf queries
From: Chris Wilson <chris@chris-wilson.co.uk> From: Tvrtko Ursulin <tvrtko.ursulin@intel.com> From: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com> The first goal is to be able to measure GPU (and invidual ring) busyness without having to poll registers from userspace. (Which not only incurs holding the forcewake lock indefinitely, perturbing the system, but also runs the risk of hanging the machine.) As an alternative we can use the perf event counter interface to sample the ring registers periodically and send those results to userspace. Functionality we are exporting to userspace is via the existing perf PMU API and can be exercised via the existing tools. For example: perf stat -a -e i915/rcs0-busy/ -I 1000 Will print the render engine busynnes once per second. All the performance counters can be enumerated (perf list) and have their unit of measure correctly reported in sysfs. v1-v2 (Chris Wilson): v2: Use a common timer for the ring sampling. v3: (Tvrtko Ursulin) * Decouple uAPI from i915 engine ids. * Complete uAPI defines. * Refactor some code to helpers for clarity. * Skip sampling disabled engines. * Expose counters in sysfs. * Pass in fake regs to avoid null ptr deref in perf core. * Convert to class/instance uAPI. * Use shared driver code for rc6 residency, power and frequency. v4: (Dmitry Rogozhkin) * Register PMU with .task_ctx_nr=perf_invalid_context * Expose cpumask for the PMU with the single CPU in the mask * Properly support pmu->stop(): it should call pmu->read() * Properly support pmu->del(): it should call stop(event, PERF_EF_UPDATE) * Introduce refcounting of event subscriptions. * Make pmu.busy_stats a refcounter to avoid busy stats going away with some deleted event. * Expose cpumask for i915 PMU to avoid multiple events creation of the same type followed by counter aggregation by perf-stat. * Track CPUs getting online/offline to migrate perf context. If (likely) cpumask will initially set CPU0, CONFIG_BOOTPARAM_HOTPLUG_CPU0 will be needed to see effect of CPU status tracking. * End result is that only global events are supported and perf stat works correctly. * Deny perf driver level sampling - it is prohibited for uncore PMU. v5: (Tvrtko Ursulin) * Don't hardcode number of engine samplers. * Rewrite event ref-counting for correctness and simplicity. * Store initial counter value when starting already enabled events to correctly report values to all listeners. * Fix RC6 residency readout. * Comments, GPL header. v6: * Add missing entry to v4 changelog. * Fix accounting in CPU hotplug case by copying the approach from arch/x86/events/intel/cstate.c. (Dmitry Rogozhkin) v7: * Log failure message only on failure. * Remove CPU hotplug notification state on unregister. v8: * Fix error unwind on failed registration. * Checkpatch cleanup. v9: * Drop the energy metric, it is available via intel_rapl_perf. (Ville Syrjälä) * Use HAS_RC6(p). (Chris Wilson) * Handle unsupported non-engine events. (Dmitry Rogozhkin) * Rebase for intel_rc6_residency_ns needing caller managed runtime pm. * Drop HAS_RC6 checks from the read callback since creating those events will be rejected at init time already. * Add counter units to sysfs so perf stat output is nicer. * Cleanup the attribute tables for brevity and readability. v10: * Fixed queued accounting. v11: * Move intel_engine_lookup_user to intel_engine_cs.c * Commit update. (Joonas Lahtinen) v12: * More accurate sampling. (Chris Wilson) * Store and report frequency in MHz for better usability from perf stat. * Removed metrics: queued, interrupts, rc6 counters. * Sample engine busyness based on seqno difference only for less MMIO (and forcewake) on all platforms. (Chris Wilson) v13: * Comment spelling, use mul_u32_u32 to work around potential GCC issue and somne code alignment changes. (Chris Wilson) v14: * Rebase. v15: * Rebase for RPS refactoring. v16: * Use the dynamic slot in the CPU hotplug state machine so that we are free to setup our state as multi-instance. Previously we were re-using the CPUHP_AP_PERF_X86_UNCORE_ONLINE slot which is neither used as multi-instance, nor owned by our driver to start with. * Register the CPU hotplug handlers after the PMU, otherwise the callback will get called before the PMU is initialized which can end up in perf_pmu_migrate_context with an un-initialized base. * Added workaround for a probable bug in cpuhp core. v17: * Remove workaround for the cpuhp bug. v18: * Rebase for drm_i915_gem_engine_class getting upstream before us. v19: * Rebase.

platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver including WMI work to provide an interface for SMBIOS tokens via sysfs and WMI support for 2017+ Dell laptop models. SMM dispatcher code is split into a separate driver followed by a new WMI dispatcher. The latter provides a character device interface to user space. The pull request contains a merge of immutable branch from Wolfram Sang in order to apply a dependent fix to the Intel CherryTrail Battery Management driver. Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0 support is added for Intel Skylake. Peaq WMI hotkeys driver gets its own maintainer and white list of supported models. Silead DMI is expanded to support few additional platforms. Tablet mode via GMMS ACPI method is added to support some ThinkPad tablets.

kcov: support comparison operands collection
Enables kcov to collect comparison operands from instrumented code. This is done by using Clang's -fsanitize=trace-cmp instrumentation (currently not available for GCC). The comparison operands help a lot in fuzz testing. E.g. they are used in Syzkaller to cover the interiors of conditional statements with way less attempts and thus make previously unreachable code reachable. To allow separate collection of coverage and comparison operands two different work modes are implemented. Mode selection is now done via a KCOV_ENABLE ioctl call with corresponding argument value.
