networking changes for the 5.10 merge window
Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. Allow more than 255 IPv4 multicast interfaces. Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. Allow more calls to same peer in RxRPC. Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. Add TC actions for implementing MPLS L2 VPNs. Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. Support sleepable BPF programs, initially targeting LSM and tracing. Add bpf_d_path() helper for returning full path for given 'struct path'. Make bpf_tail_call compatible with bpf-to-bpf calls. Allow BPF programs to call map_update_elem on sockmaps. Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). Support listing and getting information about bpf_links via the bpf syscall. Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. Add XDP support for Intel's igb driver. Support offloading TC flower classification and filtering rules to mscc_ocelot switches. Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete).

IOMMU Updates for Linux v5.10
Including: - ARM-SMMU Updates from Will: - Continued SVM enablement, where page-table is shared with CPU - Groundwork to support integrated SMMU with Adreno GPU - Allow disabling of MSI-based polling on the kernel command-line - Minor driver fixes and cleanups (octal permissions, error messages, ...) - Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when a device tries DMA on memory owned by a guest. This needs new fault-types as well as a rewrite of the IOMMU memory semaphore for command completions. - Allow broken Intel IOMMUs (wrong address widths reported) to still be used for interrupt remapping. - IOMMU UAPI updates for supporting vSVA, where the IOMMU can access address spaces of processes running in a VM. - Support for the MT8167 IOMMU in the Mediatek IOMMU driver. - Device-tree updates for the Renesas driver to support r8a7742. - Several smaller fixes and cleanups all over the place. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl+Fy9MACgkQK/BELZcB GuNxtRAA0TdYHXt6XyLWmvRAX/ySZSz6KOneZWWwpsQ9wh2/iv1PtBsrV0ltf+6g CaX4ROZUVRbV9wPD+7maBRbzxrG3QhfEaaV+K45Q2J/QE1wjkyV8qj1eORWTUUoc nis4FhGDKk2ER/Gsajy2Hjs4+6i43gdWG/+ghVGaCRo8mCZyoz1/6AyMQyN3deuO NqWOv9E7hsavZjRs/w/LXG7eSE20cZwtt//kPVJF0r9eQqC6i1eJDQj48iRqJVqd R0dwBQZaLz++qQptyKebDNlmH/3aAsb+A8nCeS7ZwHqWC1QujTWOUYWpFyPPbOmC KVsQXzTzRfnVTDECF1Pk5d3yi45KILLU3B4zDJfUJjbL3KDYjuVUvhHF/pcGcjC3 H1LWJqHSAL8sJwHvKhpi0VtQ5SOxXnLO5fGG/CZT/Xb4QyM+mkwkFLdn1TryZTR/ M4XA+QuI96TzY7HQUJdSoEDANxoBef6gPnxdDKOnK1v4hfNsPAl7o8hZkM3w0DK8 GoFZUV+vjBhFcymGcQegSNiea28Hfi+hBe+PPHCmw+tJm47cketD5uP5jJ5NGaUe MKU/QXWXc6oqeBTQT6ki5zJbJXKttbPa8eEmp+FrMatc9kruvBVhQoMbj7Vd3CA1 dC4zK9Awy7yj24ZhZfnAFx2DboCmBTUI3QKjDt9K5PRZyMeyoP8= =C0Sg -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - ARM-SMMU Updates from Will: - Continued SVM enablement, where page-table is shared with CPU - Groundwork to support integrated SMMU with Adreno GPU - Allow disabling of MSI-based polling on the kernel command-line - Minor driver fixes and cleanups (octal permissions, error messages, ...) - Secure Nested Paging Support for AMD IOMMU.

memblock: reduce number of parameters in for_each_mem_range()
Currently for_each_mem_range() and for_each_mem_range_rev() iterators are the most generic way to traverse memblock regions. As such, they have 8 parameters and they are hardly convenient to users. Most users choose to utilize one of their wrappers and the only user that actually needs most of the parameters is memblock itself. To avoid yet another naming for memblock iterators, rename the existing for_each_mem_range[_rev]() to __for_each_mem_range[_rev]() and add a new for_each_mem_range[_rev]() wrappers with only index, start and end parameters. The new wrapper nicely fits into init_unavailable_mem() and will be used in upcoming changes to simplify memblock traversals.

arm64: numa: simplify dummy_numa_init()
dummy_numa_init() loops over memblock.memory and passes nid=0 to numa_add_memblk() which essentially wraps memblock_set_node(). However, memblock_set_node() can cope with entire memory span itself, so the loop over memblock.memory regions is redundant. Using a single call to memblock_set_node() rather than a loop also fixes an issue with a buggy ACPI firmware in which the SRAT table covers some but not all of the memory in the EFI memory map. Jonathan Cameron says: This issue can be easily triggered by having an SRAT table which fails to cover all elements of the EFI memory map. This firmware error is detected and a warning printed. e.g. "NUMA: Warning: invalid memblk node 64 [mem 0x240000000-0x27fffffff]" At that point we fall back to dummy_numa_init(). However, the failed ACPI init has left us with our memblocks all broken up as we split them when trying to assign them to NUMA nodes. We then iterate over the memblocks and add them to node 0. numa_add_memblk() calls memblock_set_node() which merges regions that were previously split up during the earlier attempt to add them to different nodes during parsing of SRAT. This means elements are moved in the memblock array and we can end up in a different memblock after the call to numa_add_memblk(). Result is: Unable to handle kernel paging request at virtual address 0000000000003a40 Mem abort info: ESR = 0x96000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000004 CM = 0, WnR = 0 [0000000000003a40] user address but active_mm is swapper Internal error: Oops: 96000004 [#1] PREEMPT SMP ...

Orphan link sections were a long-standing source of obscure bugs,
because the heuristics that various linkers & compilers use to handle them (include these bits into the output image vs discarding them silently) are both highly idiosyncratic and also version dependent. Instead of this historically problematic mess, this tree by Kees Cook (et al) adds build time asserts and build time warnings if there's any orphan section in the kernel or if a section is not sized as expected. And because we relied on so many silent assumptions in this area, fix a metric ton of dependencies and some outright bugs related to this, before we can finally enable the checks on the x86, ARM and ARM64 platforms.

In terms of exciting features, this includes support for the Memory Tagging Extension which narrowly missed 5.9, hopefully allowing userspace to run with use-after-free detection in production on CPUs that support it. Work is ongoing to integrate the feature with KASAN for 5.11. Another change that I'm excited about (assuming they get the hardware right) is preparing the ASID allocator for sharing the CPU page-table with the SMMU. Those changes will also come in via Joerg with the IOMMU pull. We do stray outside of our usual directories in a few places, mostly due to core changes required by MTE. Although much of this has been Acked, there were a couple of places where we unfortunately didn't get any review feedback. Other than that, we ran into a handful of minor conflicts in -next, but nothing that should post any issues. Summary: - Userspace support for the Memory Tagging Extension introduced by Armv8.5.

seccomp: Move config option SECCOMP to arch/Kconfig
In order to make adding configurable features into seccomp easier, it's better to have the options at one single location, considering especially that the bulk of seccomp code is arch-independent. An quick look also show that many SECCOMP descriptions are outdated; they talk about /proc rather than prctl. As a result of moving the config option and keeping it default on, architectures arm, arm64, csky, riscv, sh, and xtensa did not have SECCOMP on by default prior to this and SECCOMP will be default in this change. Architectures microblaze, mips, powerpc, s390, sh, and sparc have an outdated depend on PROC_FS and this dependency is removed in this change.

cpufreq,arm,arm64: restructure definitions of arch_set_freq_scale()
Compared to other arch_* functions, arch_set_freq_scale() has an atypical weak definition that can be replaced by a strong architecture specific implementation. The more typical support for architectural functions involves defining an empty stub in a header file if the symbol is not already defined in architecture code. Some examples involve: - #define arch_scale_freq_capacity topology_get_freq_scale - #define arch_scale_freq_invariant topology_scale_freq_invariant - #define arch_scale_cpu_capacity topology_get_cpu_scale - #define arch_update_cpu_topology topology_update_cpu_topology - #define arch_scale_thermal_pressure topology_get_thermal_pressure - #define arch_set_thermal_pressure topology_set_thermal_pressure Bring arch_set_freq_scale() in line with these functions by renaming it to topology_set_freq_scale() in the arch topology driver, and by defining the arch_set_freq_scale symbol to point to the new function for arm and arm64. While there are other users of the arch_topology driver, this patch defines arch_set_freq_scale for arm and arm64 only, due to their existing definitions of arch_scale_freq_capacity. This is the getter function of the frequency invariance scale factor and without a getter function, the setter function - arch_set_freq_scale() has not purpose.

crypto: arm64: Use x16 with indirect branch to bti_c
The AES code uses a 'br x7' as part of a function called by
a macro. That branch needs a bti_j as a target. This results
in a panic as seen below. Using x16 (or x17) with an indirect
branch keeps the target bti_c.

arm64: initialize per-cpu offsets earlier
The current initialization of the per-cpu offset register is difficult to follow and this initialization is not always early enough for upcoming instrumentation with KCSAN, where the instrumentation callbacks use the per-cpu offset. To make it possible to support KCSAN, and to simplify reasoning about early bringup code, let's initialize the per-cpu offset earlier, before we run any C code that may consume it. To do so, this patch adds a new init_this_cpu_offset() helper that's called before the usual primary/secondary start functions. For consistency, this is also used to re-initialize the per-cpu offset after the runtime per-cpu areas have been allocated (which can change CPU0's offset). So that init_this_cpu_offset() isn't subject to any instrumentation that might consume the per-cpu offset, it is marked with noinstr, preventing instrumentation.

xen/arm: do not setup the runstate info page if kpti is enabled
The VCPUOP_register_runstate_memory_area hypercall takes a virtual address of a buffer as a parameter. The semantics of the hypercall are such that the virtual address should always be valid. When KPTI is enabled and we are running userspace code, the virtual address is not valid, thus, Linux is violating the semantics of VCPUOP_register_runstate_memory_area. Do not call VCPUOP_register_runstate_memory_area when KPTI is enabled.
