Pull x86 MMIO stale data fixes from Thomas Gleixner: "Yet another hw vulnerability with a software mitigation: Processor MMIO Stale Data. They are a class of MMIO-related weaknesses which can expose stale data by propagating it into core fill buffers. Data which can then be leaked using the usual speculative execution methods.

Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment
2022-06-11wireguard: selftests: use maximum cpu features and allow rng seedingJason A. Donenfeld3-15/+19
By forcing the maximum CPU that QEMU has available, we expose additional capabilities, such as the RNDR instruction, which increases test coverage. This then allows the CI to skip the fake seeding step in some cases. Also enable STRICT_KERNEL_RWX to catch issues related to early jump labels when the RNG is initialized at boot.

hyperv_clock doesn't always give a stable test result, especially with AMD CPUs. The test compares Hyper-V MSR clocksource (acquired either with rdmsr() from within the guest or KVM_GET_MSRS from the host) against rdtsc(). To increase the accuracy, increase the measured delay (done with nop loop) by two orders of magnitude and take the mean rdtsc() value before and after rdmsr()/KVM_GET_MSRS.

Pull initial Loongarch architecture code from Arnd Bergmann: "This is the majority of the loongarch architecture code, including the final system call interface and all core functionality. It still misses three sets of peripheral but vital patches to add support for other subsystems, which have yet to pass review: - The drivers/firmware/efi stub for booting from a standard UEFI firmware implementation. Both the original custom boot interface and a draft implementation of the EFI stub did not make it, so it is currently impossible to boot the kernel, until the loongarch specific portions get accepted into the UEFI subsystem - The drivers/irqchip/irq-loongson-*.c drivers are shared with the the MIPS port, but currently lack support for ACPI based booting, which will get merged through the irqchip subsystem. - Similarly, the drivers/pci/controller/pci-loongson.c needs to be modified for ACPI support, which will be merged through the PCI subsystem. While the port cannot actually be used before all the above are merged, having it in 5.19 helps to establish the user space ABI for the libc ports to build on, and to help any treewide changes in the mainline kernel get applied here as well.

This leads to perf c2c tool cannot locate the memory node for samples. This patch enables configuration 'pa_enable' for Arm SPE events, so the physical address packet can be traced, finally this can allow perf c2c tool to locate properly for memory node.

2022-06-03perf record: Support sample-read topdown metric group for hybrid platformsZhengjun Xing3-18/+13
With the hardware TopDown metrics feature, the sample-read feature should be supported for a TopDown group, e.g., sample a non-topdown event and read a Topdown metric group. But the current perf record code errors are out. For a TopDown metric group,the slots event must be the leader of the group, but the leader slots event doesn't support sampling. To support sample-read the TopDown metric group, uses the 2nd event of the group as the "leader" for the purposes of sampling. Only the platform with the TopDown metric feature supports sample-read the topdown group. In commit acb65150a47c ("perf record: Support sample-read topdown metric group"), it adds arch_topdown_sample_read() to indicate whether the TopDown group supports sample-read, it should only work on the non-hybrid systems, this patch extends the support for hybrid platforms. Before: # ./perf record -e "{cpu_core/slots/,cpu_core/cycles/,cpu_core/topdown-retiring/}:S" -a sleep 1 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/topdown-retiring/). /bin/dmesg | grep -i perf may provide additional information.

2022-06-03perf unwind: Fix segbase for ld.lld linked objectsFangrui Song2-30/+77
segbase is the address of .eh_frame_hdr and table_data is segbase plus the header size. find_proc_info computes segbase as `map->start + segbase - map->pgoff` which is wrong when * .eh_frame_hdr and .text are in different PT_LOAD program headers * and their p_vaddr difference does not equal their p_offset difference Since 10.0, ld.lld's default --rosegment -z noseparate-code layout has such R and RX PT_LOAD program headers. ld.lld (default) => perf report fails to unwind `perf record --call-graph dwarf` recorded data ld.lld --no-rosegment => ok (trivial, no R PT_LOAD) ld.lld -z separate-code => ok but by luck: there are two PT_LOAD but their p_vaddr difference equals p_offset difference ld.bfd -z noseparate-code => ok (trivial, no R PT_LOAD) ld.bfd -z separate-code (default for Linux/x86) => ok but by luck: there are two PT_LOAD but their p_vaddr difference equals p_offset difference To fix the issue, compute segbase as dso's base address plus PT_GNU_EH_FRAME's p_vaddr. The base address is computed by iterating over all dso-associated maps and then subtract the first PT_LOAD p_vaddr (the minimum guaranteed by generic ABI) from the minimum address. In libunwind, find_proc_info transitively called by unw_step is cached, so the iteration overhead is acceptable.

2022-06-03perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systemsZhengjun Xing1-1/+1
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need extend API arch_evsel__must_be_in_group() to support hybrid systems. In the origin code, for hybrid system event "cpu_core/slots/", the output of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be "true"). Currently only one API evsel__remove_from_group() calls it. In evsel__remove_from_group(), it adds the second condition to check, so the output of evsel__remove_from_group() still is correct. That's the reason why there isn't an instant error. I'd like to fix the issue found in API arch_evsel__must_be_in_group() in case someone else using the function in the other place.

Pull driver core updates from Greg KH: "Here is the set of driver core changes for 5.19-rc1. Lots of tiny driver core changes and cleanups happened this cycle, but the two major things are: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes include: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue. But I didn't get it merged into my tree before 5.18-final came out, so it has not gotten any linux-next testing. I'll send the fixup patches (there are 2) as a follow-on series to this pull request.

2022-06-03bitmap: Fix return values to be unsignedKees Cook2-18/+19
Both nodemask and bitmap routines had mixed return values that provided potentially signed return values that could never happen. This was leading to the compiler getting confusing about the range of possible return values (it was thinking things could be negative where they could not be). In preparation for fixing nodemask, fix all the bitmap routines that should be returning unsigned (or bool) values.

Delay accounting does not track the delay of write-protect copy. When tasks trigger many write-protect copys(include COW and unsharing of anonymous pages[1]), it may spend a amount of time waiting for them. To get the delay of tasks in write-protect copy, could help users to evaluate the impact of using KSM or fork() or GUP.

2022-05-31net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_naArun Ajith S1-12/+11
RFC 9131 changes default behaviour of handling RX of NA messages when the corresponding entry is absent in the neighbour cache. The current implementation is limited to accept just unsolicited NAs. However, the RFC is more generic where it also accepts solicited NAs. Both types should result in adding a STALE entry for this case. Expand accept_untracked_na behaviour to also accept solicited NAs to be compliant with the RFC and rename the sysctl knob to accept_untracked_na.
