The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed.

2020-10-30net: bridge: mcast: add support for raw L2 multicast groupsNikolay Aleksandrov1-0/+1
Extend the bridge multicast control and data path to configure routes for L2 (non-IP) multicast groups. The uapi struct br_mdb_entry union u is extended with another variant, mac_addr, which does not change the structure size, and which is valid when the proto field is zero. To be compatible with the forwarding code that is already in place, which acts as an IGMP/MLD snooping bridge with querier capabilities, we need to declare that for L2 MDB entries (for which there exists no such thing as IGMP/MLD snooping/querying), that there is always a querier. Otherwise, these entries would be flooded to all bridge ports and not just to those that are members of the L2 multicast group. Needless to say, only permanent L2 multicast groups can be installed on a bridge port.

2020-10-30drm/fourcc: Add AMD DRM modifiers.Bas Nieuwenhuizen1-0/+115
This adds modifiers for GFX9+ AMD GPUs. As the modifiers need a lot of parameters I split things out in getters and setters. - Advantage: simplifies the code a lot - Disadvantage: Makes it harder to check that you're setting all the required fields. The tiling modes seem to change every generation, but the structure of what each tiling mode is good for stays really similar. As such the core of the modifier is - the tiling mode - a version. Not explicitly a GPU generation, but splitting out a new set of tiling equations. Sometimes one or two tiling modes stay the same and for those we specify a canonical version. Then we have a bunch of parameters on how the compression works. Different HW units have different requirements for these and we actually have some conflicts here. e.g. the render backends need a specific alignment but the display unit only works with unaligned compression surfaces. To work around that we have a DCC_RETILE option where both an aligned and unaligned compression surface are allocated and a writer has to sync the aligned surface to the unaligned surface on handoff. Finally there are some GPU parameters that participate in the tiling equations. These are constant for each GPU on the rendering/texturing side. The display unit is very flexible however and supports all of them :| Some estimates: - Single GPU, render+texture: ~10 modifiers - All possible configs in a gen, display: ~1000 modifiers - Configs of actually existing GPUs in a gen: ~100 modifiers For formats with a single plane everything gets put in a separate DRM plane. However, this doesn't fit for some YUV formats, so if the format has >1 plane, we let the driver pack the surfaces into 1 DRM plane per format plane. This way we avoid X11 rendering onto the frontbuffer with DCC, but still fit into 4 DRM planes.

2020-10-29bridge: cfm: Kernel space implementation of CFM. MEP create/delete.Henrik Bjoernlund1-0/+23
This is the first commit of the implementation of the CFM protocol according to 802.1Q section 12.14. It contains MEP instance create, delete and configuration. Connectivity Fault Management (CFM) comprises capabilities for detecting, verifying, and isolating connectivity failures in Virtual Bridged Networks. These capabilities can be used in networks operated by multiple independent organizations, each with restricted management access to each others equipment. CFM functions are partitioned as follows: - Path discovery - Fault detection - Fault verification and isolation - Fault notification - Fault recovery Interface consists of these functions: br_cfm_mep_create() br_cfm_mep_delete() br_cfm_mep_config_set() br_cfm_cc_config_set() br_cfm_cc_peer_mep_add() br_cfm_cc_peer_mep_remove() A MEP instance is created by br_cfm_mep_create() -It is the Maintenance association End Point described in 802.1Q section 19.2. -It is created on a specific level (1-7) and is assuring that no CFM frames are passing through this MEP on lower levels. -It initiates and validates CFM frames on its level. -It can only exist on a port that is related to a bridge. -Attributes given cannot be changed until the instance is deleted. A MEP instance can be deleted by br_cfm_mep_delete(). A created MEP instance has attributes that can be configured by br_cfm_mep_config_set(). A MEP Continuity Check feature can be configured by br_cfm_cc_config_set() The Continuity Check Receiver state machine can be enabled and disabled. According to 802.1Q section 19.2.8 A MEP can have Peer MEPs added and removed by br_cfm_cc_peer_mep_add() and br_cfm_cc_peer_mep_remove() The Continuity Check feature can maintain connectivity status on each added Peer MEP.

2020-10-29wimax: move out to stagingArnd Bergmann2-811/+0
There are no known users of this driver as of October 2020, and it will be removed unless someone turns out to still need it in future releases. According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there have been many public wimax networks, but it appears that many of these have migrated to LTE or discontinued their service altogether. As most PCs and phones lack WiMAX hardware support, the remaining networks tend to use standalone routers. These almost certainly run Linux, but not a modern kernel or the mainline wimax driver stack. NetworkManager appears to have dropped userspace support in 2015 https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org site had already shut down earlier. WiMax is apparently still being deployed on airport campus networks ("AeroMACS"), but in a frequency band that was not supported by the old Intel 2400m (used in Sandy Bridge laptops and earlier), which is the only driver using the kernel's wimax stack. Move all files into drivers/staging/wimax, including the uapi header files and documentation, to make it easier to remove it when it gets to that. Only minimal changes are made to the source files, in order to make it possible to port patches across the move. Also remove the MAINTAINERS entry that refers to a broken mailing list and website.

2020-10-29perf/core: Add support for PERF_SAMPLE_CODE_PAGE_SIZEStephane Eranian1-1/+3
When studying code layout, it is useful to capture the page size of the sampled code address. Add a new sample type for code page size. The new sample type requires collecting the ip. The code page size can be calculated from the NMI-safe perf_get_page_size(). For large PEBS, it's very unlikely that the mapping is gone for the earlier PEBS records. Enable the feature for the large PEBS. The worst case is that page-size '0' is returned.

2020-10-29perf/core: Add PERF_SAMPLE_DATA_PAGE_SIZEKan Liang1-1/+3
Current perf can report both virtual addresses and physical addresses, but not the MMU page size. Without the MMU page size information of the utilized page, users cannot decide whether to promote/demote large pages to optimize memory usage. Add a new sample type for the data MMU page size. Current perf already has a facility to collect data virtual addresses. A page walker is required to walk the pages tables and calculate the MMU page size from a given virtual address. On some platforms, e.g., X86, the page walker is invoked in an NMI handler. So the page walker must be NMI-safe and low overhead. Besides, the page walker should work for both user and kernel virtual address. The existing generic page walker, e.g., walk_page_range_novma(), is a little bit complex and doesn't guarantee the NMI-safe. The follow_page() is only for user-virtual address. Add a new function perf_get_page_size() to walk the page tables and calculate the MMU page size. In the function: - Interrupts have to be disabled to prevent any teardown of the page tables. - For user space threads, the current->mm is used for the page walker. For kernel threads and the like, the current->mm is NULL. The init_mm is used for the page walker. The active_mm is not used here, because it can be NULL. Quote from Peter Zijlstra, "context_switch() can set prev->active_mm to NULL when it transfers it to @next. It does this before @current is updated. So an NMI that comes in between this active_mm swizzling and updating @current will see !active_mm." - The MMU page size is calculated from the page table level. The method should work for all architectures, but it has only been verified on X86. Should there be some architectures, which support perf, where the method doesn't work, it can be fixed later separately. Reporting the wrong page size would not be fatal for the architecture. Some under discussion features may impact the method in the future. Quote from Dave Hansen, "There are lots of weird things folks are trying to do with the page tables, like Address Space Isolation. For instance, if you get a perf NMI when running userspace, current->mm->pgd is *different* than the PGD that was in use when userspace was running. It's close enough today, but it might not stay that way." If the case happens later, lots of consecutive page walk errors will happen. The worst case is that lots of page-size '0' are returned, which would not be fatal. In the perf tool, a check is implemented to detect this case. Once it happens, a kernel patch could be implemented accordingly then.

2020-10-22bpf: Fix bpf_redirect_neigh helper api to support supplying nexthopToke Høiland-Jørgensen1-4/+18
Based on the discussion in [0], update the bpf_redirect_neigh() helper to accept an optional parameter specifying the nexthop information. This makes it possible to combine bpf_fib_lookup() and bpf_redirect_neigh() without incurring a duplicate FIB lookup - since the FIB lookup helper will return the nexthop information even if no neighbour is present, this can simply be passed on to bpf_redirect_neigh() if bpf_fib_lookup() returns BPF_FIB_LKUP_RET_NO_NEIGH. Thus fix & extend it before helper API is frozen.

2020-10-21kvm: x86: only provide PV features if enabled in guest's CPUIDOliver Upton1-0/+1
KVM unconditionally provides PV features to the guest, regardless of the configured CPUID. An unwitting guest that doesn't check KVM_CPUID_FEATURES before use could access paravirt features that userspace did not intend to provide. Fix this by checking the guest's CPUID before performing any paravirtual operations. Introduce a capability, KVM_CAP_ENFORCE_PV_FEATURE_CPUID, to gate the aforementioned enforcement. Migrating a VM from a host w/o this patch to a host with this patch could silently change the ABI exposed to the guest, warranting that we default to the old behavior and opt-in for the new one.
