git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers: - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux Pull sh updates from John Paul Adrian Glaubitz: "The majority of improvements are coming from Geert Uytterhoeven who took the time to fix a total of 30 cases of "-Wmissing-prototypes" compiler warnings, either by adding a missing header include, defining the missing forward declarations or making the functions in question static. In the case of several DMA functions, the fix was to actually just remove them as they were added but never used. Another one of these warnings was eliminated by removing the left-over sh5 cache handling support, a change that was suggested by Yoshinori Sato and, finally, the last of these warnings was fixed by guarding the function setup_profiling_timer() with CONFIG_PROFILING. While at it, Geert also removed two unneeded casts to kprobe_opcode_t in the kprobes code. Another change was contributed by Guenter Roeck to fix errors that were reported during checksum unit tests. The fix actually reverts the older change cadc4e1a2b4d ("sh: Handle calling csum_partial with misaligned data") which turned to be incorrect. It remains to be investigated whether there is a better way to handle misaligned data in csum_partial(). A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI controller spi-max-frequency property in the device tree source file for the J2 device platform while Uwe Kleine-König converted the push-switch driver to have its callback function return void, a change that is currently being applied to all drivers throughout the kernel in order to avoid resource leaks.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 interrupt handling updates from Thomas Gleixner: "Add support for posted interrupts on bare metal. Posted interrupts is a virtualization feature which allows to inject interrupts directly into a guest without host interaction. The VT-d interrupt remapping hardware sets the bit which corresponds to the interrupt vector in a vector bitmap which is either used to inject the interrupt directly into the guest via a virtualized APIC or in case that the guest is scheduled out provides a host side notification interrupt which informs the host that an interrupt has been marked pending in the bitmap. This can be utilized on bare metal for scenarios where multiple devices, e.g. NVME storage, raise interrupts with a high frequency. In the default mode these interrupts are handles independently and therefore require a full roundtrip of interrupt entry/exit. Utilizing posted interrupts this roundtrip overhead can be avoided by coalescing these interrupt entries to a single entry for the posted interrupt notification. The notification interrupt then demultiplexes the pending bits in a memory based bitmap and invokes the corresponding device specific handlers. Depending on the usage scenario and device utilization throughput improvements between 10% and 130% have been measured. As this is only relevant for high end servers with multiple device queues per CPU attached and counterproductive for situations where interrupts are arriving at distinct times, the functionality is opt-in via a kernel command line parameter" * tag 'x86-irq-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/irq: Use existing helper for pending vector check iommu/vt-d: Enable posted mode for device MSIs iommu/vt-d: Make posted MSI an opt-in command line option x86/irq: Extend checks for pending vectors to posted interrupts x86/irq: Factor out common code for checking pending interrupts x86/irq: Install posted MSI notification handler x86/irq: Factor out handler invocation from common_interrupt() x86/irq: Set up per host CPU posted interrupt descriptors x86/irq: Reserve a per CPU IDT vector for posted MSIs x86/irq: Add a Kconfig option for posted MSI x86/irq: Remove bitfields in posted interrupt descriptor x86/irq: Unionize PID.PIR for 64bit access w/o casting KVM: VMX: Move posted interrupt descriptor out of VMX code

To make this more user friendly, provide an extenstion to interrupt statistics which allows to take snapshots and an interface to retrieve the delta to the snapshot. Use this new mechanism in the watchdog code to do a two stage lockup analysis by taking the snapshot and printing the deltas for the topmost active interrupts on the second trigger. Note: This contains both the interrupt and the watchdog changes as the latter depend on the former obviously. - Avoid summation loops in the /proc/interrupts output and use the global counter when possible - Skip suspended interrupts on CPU hotplug operations to ensure that they are not delivered before the system resumes the device drivers when coming out of suspend. - On CPU hot-unplug interrupts which are affine to the outgoing CPU are migrated to a different CPU in the affinity mask. This can fail when the CPUs have no vectors left. Instead of giving up try to migrate it to any online CPU and thereby breaking the affinity setting in order to prevent a stale device interrupt which targets an offline CPU - The usual small cleanups Driver code: - Support for the RISCV AIA MSI controller - Make the interrupt allocation for the Loongson PCH controller more flexible to prevent vector exhaustion - The usual set of cleanups and fixes all over the place" * tag 'irq-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (51 commits) irqchip/gic-v3-its: Remove BUG_ON in its_vpe_irq_domain_alloc cpuidle: Avoid explicit cpumask allocation on stack irqchip/sifive-plic: Avoid explicit cpumask allocation on stack irqchip/riscv-aplic-direct: Avoid explicit cpumask allocation on stack irqchip/loongson-eiointc: Avoid explicit cpumask allocation on stack irqchip/gic-v3-its: Avoid explicit cpumask allocation on stack irqchip/irq-bcm6345-l1: Avoid explicit cpumask allocation on stack cpumask: Introduce cpumask_first_and_and() irqchip/irq-brcmstb-l2: Avoid saving mask on shutdown genirq: Reuse irq_is_nmi() genirq/cpuhotplug: Retry with cpu_online_mask when migration fails genirq/cpuhotplug: Skip suspended interrupts when restoring affinity arm64: dts: st: Add interrupt parent to pinctrl on stm32mp251 arm64: dts: st: Add exti1 and exti2 nodes on stm32mp251 ARM: dts: stm32: List exti parent interrupts on stm32mp131 ARM: dts: stm32: List exti parent interrupts on stm32mp151 arm64: Kconfig.platforms: Enable STM32_EXTI for ARCH_STM32 irqchip/stm32-exti: Mark events reserved with RIF configuration check irqchip/stm32-exti: Skip secure events irqchip/stm32-exti: Convert driver to standard PM ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 timers update from Thomas Gleixner: "A single update for the TSC synchronixation sanity checks: The sad state of TSC being notoriously non-sychronized for several decades caused the kernel to grow quite rigorous sanity checks to detect whether the TSC is valid to be used for timekeeping. The TSC ADJUST MSR provides the offset between the initial TSC value after hardware reset and later modifications. This allows to detect cases where firmware tampers with the TSC and also allows to correct the firmware induced damage by resetting the offset in a controlled way. The universal correct rule is that the TSC ADJUST value has to be consistent within all CPUs of a socket. The kernel further assumes that the TSC offset should be consistent between sockets. That's not really correct as systems with a huge number of sockets are not architecurally guaranteed to reset the per socket TSC base synchronously. In case that the per socket offset is not consistent the kernel resets it to the offset of the boot CPU and then does a synchronization check which corrects for the inter socket delays. That works most of the time, but it is suboptimal as the firmware has eventually better information about the per socket offset and on sane systems that offset should just work in the validation checks" * tag 'x86-timers-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc: Trust initial offset in architectural TSC-adjust MSRs

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timers and timekeeping updates from Thomas Gleixner: "Core code: - Make timekeeping and VDSO time readouts resilent against math overflow: In guest context the kernel is prone to math overflow when the host defers the timer interrupt due to overload, malfunction or malice. This can be mitigated by checking the clocksource delta for the maximum deferrement which is readily available. If that value is exceeded then the code uses a slowpath function which can handle the multiplication overflow. This functionality is enabled unconditionally in the kernel, but made conditional in the VDSO code. The latter is conditional because it allows architectures to optimize the check so it is not causing performance regressions. On X86 this is achieved by reworking the existing check for negative TSC deltas as a negative delta obviously exceeds the maximum deferrement when it is evaluated as an unsigned value. That avoids two conditionals in the hotpath and allows to hide both the negative delta and the large delta handling in the same slow path. - Add an initial minimal ktime_t abstraction for Rust - The usual boring cleanups and enhancements Drivers: - Boring updates to device trees and trivial enhancements in various drivers" * tag 'timers-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) clocksource/drivers/arm_arch_timer: Mark hisi_161010101_oem_info const clocksource/drivers/timer-ti-dm: Remove an unused field in struct dmtimer clocksource/drivers/renesas-ostm: Avoid reprobe after successful early probe clocksource/drivers/renesas-ostm: Allow OSTM driver to reprobe for RZ/V2H(P) SoC dt-bindings: timer: renesas: ostm: Document Renesas RZ/V2H(P) SoC rust: time: doc: Add missing C header links clocksource: Make the int help prompt unit readable in ncurses hrtimer: Rename __hrtimer_hres_active() to hrtimer_hres_active() timerqueue: Remove never used function timerqueue_node_expires() rust: time: Add Ktime vdso: Fix powerpc build U64_MAX undeclared error clockevents: Convert s[n]printf() to sysfs_emit() clocksource: Convert s[n]printf() to sysfs_emit() clocksource: Make watchdog and suspend-timing multiplication overflow safe timekeeping: Let timekeeping_cycles_to_ns() handle both under and overflow timekeeping: Make delta calculation overflow safe timekeeping: Prepare timekeeping_cycles_to_ns() for overflow safety timekeeping: Fold in timekeeping_delta_to_ns() timekeeping: Consolidate timekeeping helpers timekeeping: Refactor timekeeping helpers ...

The main changes are: 1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi. 2) Add BPF range computation improvements to the verifier in particular around XOR and OR operators, refactoring of checks for range computation and relaxing MUL range computation so that src_reg can also be an unknown scalar, from Cupertino Miranda. 3) Add support to attach kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. Session mode is a common use-case for tetragon and bpftrace, from Jiri Olsa. 4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf as well as BPF selftest's struct_ops handling, from Andrii Nakryiko. 5) Improvements to BPF selftests in context of BPF gcc backend, from Jose E. Marchesi & David Faust. 6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test- -style in order to retire the old test, run it in BPF CI and additionally expand test coverage, from Jordan Rife. 7) Big batch for BPF selftest refactoring in order to remove duplicate code around common network helpers, from Geliang Tang. 8) Another batch of improvements to BPF selftests to retire obsolete bpf_tcp_helpers.h as everything is available vmlinux.h, from Martin KaFai Lau. 9) Fix BPF map tear-down to not walk the map twice on free when both timer and wq is used, from Benjamin Tissoires. 10) Fix BPF verifier assumptions about socket->sk that it can be non-NULL, from Alexei Starovoitov. 11) Change BTF build scripts to using --btf_features for pahole v1.26+, from Alan Maguire. 12) Small improvements to BPF reusing struct_size() and krealloc_array(), from Andy Shevchenko. 13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions, from Ilya Leoshkevich. 14) Extend TCP ->cong_control() callback in order to feed in ack and flag parameters and allow write-access to tp->snd_cwnd_stamp from BPF program, from Miao Xu. 15) Add support for internal-only per-CPU instructions to inline bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs, from Puranjay Mohan. 16) Follow-up to remove the redundant ethtool.h from tooling infrastructure, from Tushar Vyavahare. 17) Extend libbpf to support "module:<function>" syntax for tracing programs, from Viktor Malik. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (119 commits) bpf: make list_for_each_entry portable bpf: ignore expected GCC warning in test_global_func10.c bpf: disable strict aliasing in test_global_func9.c selftests/bpf: Free strdup memory in xdp_hw_metadata selftests/bpf: Fix a few tests for GCC related warnings. bpf: avoid gcc overflow warning in test_xdp_vlan.c tools: remove redundant ethtool.h from tooling infra selftests/bpf: Expand ATTACH_REJECT tests selftests/bpf: Expand getsockname and getpeername tests sefltests/bpf: Expand sockaddr hook deny tests selftests/bpf: Expand sockaddr program return value tests selftests/bpf: Retire test_sock_addr.(c|sh) selftests/bpf: Remove redundant sendmsg test cases selftests/bpf: Migrate ATTACH_REJECT test cases selftests/bpf: Migrate expected_attach_type tests selftests/bpf: Migrate wildcard destination rewrite test selftests/bpf: Migrate sendmsg6 v4 mapped address tests selftests/bpf: Migrate sendmsg deny test cases selftests/bpf: Migrate WILDCARD_IP test selftests/bpf: Handle SYSCALL_EPERM and SYSCALL_ENOTSUPP test cases ... ==================== Link: https://lore.kernel.org/r/20240513134114.17575-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

This approach bypasses per-cpu nocb-lists thus sync-users do not depend on nocb-list length and how fast regular callbacks are processed. - RCU tasks: switch tasks RCU grace periods to sleep at TASK_IDLE priority, fix some comments, add some diagnostic warning to the exit_tasks_rcu_start() and fix a buffer overflow in the show_rcu_tasks_trace_gp_kthread(). - RCU torture: Increase memory to guest OS, fix a Tasks Rude RCU testing, some updates for TREE09, dump mode information to debug GP kthread state, remove redundant READ_ONCE(), fix some comments about RCU_TORTURE_PIPE_LEN and pipe_count, remove some redundant pointer initialization, fix a hung splat task by when the rcutorture tests start to exit, fix invalid context warning, add '--do-kvfree' parameter to torture test and use slow register unregister callbacks only for rcutype test. * tag 'rcu.next.v6.10' of https://github.com/urezki/linux: (48 commits) rcutorture: Use rcu_gp_slow_register/unregister() only for rcutype test torture: Scale --do-kvfree test time rcutorture: Fix invalid context warning when enable srcu barrier testing rcutorture: Make stall-tasks directly exit when rcutorture tests end rcutorture: Removing redundant function pointer initialization rcutorture: Make rcutorture support print rcu-tasks gp state rcutorture: Use the gp_kthread_dbg operation specified by cur_ops rcutorture: Re-use value stored to ->rtort_pipe_count instead of re-reading rcutorture: Fix rcu_torture_one_read() pipe_count overflow comment rcutorture: Remove extraneous rcu_torture_pipe_update_one() READ_ONCE() rcu: Allocate WQ with WQ_MEM_RECLAIM bit set rcu: Support direct wake-up of synchronize_rcu() users rcu: Add a trace event for synchronize_rcu_normal() rcu: Reduce synchronize_rcu() latency rcu: Fix buffer overflow in print_cpu_stall_info() rcu: Mollify sparse with RCU guard rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow rcu-tasks: Fix the comments for tasks_rcu_exit_srcu_stall_timer rcu-tasks: Replace exit_tasks_rcu_start() initialization with WARN_ON_ONCE() rcu: Remove redundant CONFIG_PROVE_RCU #if condition ...

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull alpha updates from Arnd Bergmann: "I had investigated dropping support for alpha EV5 and earlier a while ago after noticing that this is the only supported CPU family in the kernel without native byte access and that Debian has already dropped support for this generation last year [1] in order to improve performance for the newer machines. This topic came up again when Paul McKenney noticed that parts of the RCU code already rely on byte access and do not work on alpha EV5 reliably, so we decided on using my series to avoid the problem entirely. Al Viro did another series for alpha to address all the known build issues. I rebased his patches without any further changes and included it as a baseline for my work here to avoid conflicts and allow backporting the fixes to stable kernels for the now removed hardware support as well" [ I dearly loved alpha back in the days, but the lack of byte and word operations was a horrible mistake and made everything worse - including very much the crazy IO contortions that resulted from it. It certainly wasn't the only mistake in the architecture, but it's the first-order issue. So while it's a bit sad to see the support for my first alpha go away, if you want to run museum hardware, maybe you should use museum kernels.. - Linus ] * tag 'asm-generic-alpha' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: alpha: drop pre-EV56 support alpha: cabriolet: remove EV5 CPU support alpha: remove LCA and APECS based machines alpha: sable: remove early machine support alpha: remove DECpc AXP150 (Jensen) support alpha: trim the unused stuff from asm-offsets.c alpha: jensen, t2 - make __EXTERN_INLINE same as for the rest alpha: core_lca: take the unused functions out alpha: missing includes alpha: sys_sio: fix misspelled ifdefs alpha: don't make functions public without a reason alpha: add clone3() support alpha: fix modversions for strcpy() et.al. alpha: sort scr_mem{cpy,move}w() out

This enables support of new CMG data formats in userspace without the need for kernel changes - Add a per-channel-path sysfs attribute "speed_bps" that provides the operating speed in bits per second or 0 if the operating speed is not available - The CIO tracepoint subchannel-type field "st" is incorrectly set to the value of subchannel-enabled SCHIB "ena" field. Fix that - Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS - Consider the maximum physical address available to a DCSS segment (512GB) when memory layout is set up - Simplify the virtual memory layout setup by reducing the size of identity mapping vs vmemmap overlap - Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory. This will allow to place the kernel image next to kernel modules - Move everyting KASLR related from <asm/setup.h> to <asm/page.h> - Put virtual memory layout information into a structure to improve code generation - Currently __kaslr_offset is the kernel offset in both physical and virtual memory spaces. Uncouple these offsets to allow uncoupling of the addresses spaces - Currently the identity mapping base address is implicit and is always set to zero. Make it explicit by putting into __identity_base persistent boot variable and use it in proper context - Introduce .amode31 section start and end macros AMODE31_START and AMODE31_END - Introduce OS_INFO entries that do not reference any data in memory, but rather provide only values - Store virtual memory layout in OS_INFO. It is read out by makedumpfile, crash and other tools - Store virtual memory layout in VMCORE_INFO. It is read out by crash and other tools when /proc/kcore device is used - Create additional PT_LOAD ELF program header that covers kernel image only, so that vmcore tools could locate kernel text and data when virtual and physical memory spaces are uncoupled - Uncouple physical and virtual address spaces - Map kernel at fixed location when KASLR mode is disabled. The location is defined by CONFIG_KERNEL_IMAGE_BASE kernel configuration value. - Rework deployment of kernel image for both compressed and uncompressed variants as defined by CONFIG_KERNEL_UNCOMPRESSED kernel configuration value - Move .vmlinux.relocs section in front of the compressed kernel. The interim section rescue step is avoided as result - Correct modules thunk offset calculation when branch target is more than 2GB away - Kernel modules contain their own set of expoline thunks. Now that the kernel modules area is less than 4GB away from kernel expoline thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN the default if the compiler supports it - userfaultfd can insert shared zeropages into processes running VMs, but that is not allowed for s390. Fallback to allocating a fresh zeroed anonymous folio and insert that instead - Re-enable shared zeropages for non-PV and non-skeys KVM guests - Rename hex2bitmap() to ap_hex2bitmap() and export it for external use - Add ap_config sysfs attribute to provide the means for setting or displaying adapters, domains and control domains assigned to a vfio-ap mediated device in a single operation - Make vfio_ap_mdev_link_queue() ignore duplicate link requests - Add write support to ap_config sysfs attribute to allow atomic update a vfio-ap mediated device state - Document ap_config sysfs attribute - Function os_info_old_init() is expected to be called only from a regular kdump kernel. Enable it to be called from a stand-alone dump kernel - Address gcc -Warray-bounds warning and fix array size in struct os_info - s390 does not support SMBIOS, so drop unneeded CONFIG_DMI checks - Use unwinder instead of __builtin_return_address() with ftrace to prevent returning of undefined values - Sections .hash and .gnu.hash are only created when CONFIG_PIE_BUILD kernel is enabled.
