ARM64:
* Fix confusion with implicitly-shifted MDCR_EL2 masks breaking
SPE/TRBE initialization.
* Align nested page table walker with the intended memory attribute
combining rules of the architecture.
* Prevent userspace from constraining the advertised ASID width,
avoiding horrors of guest TLBIs not matching the intended context in
hardware.
* Don't leak references on LPIs when insertion into the translation
cache fails.
RISC-V:
* Replace csr_write() with csr_set() for HVIEN PMU overflow bit.
x86:
* Cache CPUID.0xD XSTATE offsets+sizes during module init - On Intel's
Emerald Rapids CPUID costs hundreds of cycles and there are a lot of
leaves under 0xD. Getting rid of the CPUIDs during nested VM-Enter and
VM-Exit is planned for the next release, for now just cache them: even
on Skylake that is 40% faster.

bpf: Avoid deadlock caused by nested kprobe and fentry bpf programs
BPF program types like kprobe and fentry can cause deadlocks in certain situations. If a function takes a lock and one of these bpf programs is hooked to some point in the function's critical section, and if the bpf program tries to call the same function and take the same lock it will lead to deadlock. These situations have been reported in the following bug reports. In percpu_freelist - Link: https://lore.kernel.org/bpf/CAADnVQLAHwsa+2C6j9+UC6ScrDaN9Fjqv1WjB1pP9AzJLhKuLQ@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEYm+9zduStsZaDnq93q1jPLqO-PiKX9jy0MuL8LCXmCrQ@mail.gmail.com/T/ In bpf_lru_list - Link: https://lore.kernel.org/bpf/CAPPBnEajj+DMfiR_WRWU5=6A7KKULdB5Rob_NJopFLWF+i9gCA@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEZQDVN6VqnQXvVqGoB+ukOtHGZ9b9U0OLJJYvRoSsMY_g@mail.gmail.com/T/ Link: https://lore.kernel.org/bpf/CAPPBnEaCB1rFAYU7Wf8UxqcqOWKmRPU1Nuzk3_oLk6qXR7LBOA@mail.gmail.com/T/ Similar bugs have been reported by syzbot.

The bugs reported by syzbot are due to tracepoint bpf programs being called in the critical sections. This patch does not aim to fix deadlocks caused by tracepoint programs. However, it does prevent deadlocks from occurring in similar situations due to kprobe and fentry programs.

bpf: Augment raw_tp arguments with PTR_MAYBE_NULL
Arguments to a raw tracepoint are tagged as trusted, which carries the semantics that the pointer will be non-NULL. However, in certain cases, a raw tracepoint argument may end up being NULL. More context about this issue is available in [0]. Thus, there is a discrepancy between the reality, that raw_tp arguments can actually be NULL, and the verifier's knowledge, that they are never NULL, causing explicit NULL check branch to be dead code eliminated. A previous attempt [1], i.e. the second fixed commit, was made to simulate symbolic execution as if in most accesses, the argument is a non-NULL raw_tp, except for conditional jumps. This tried to suppress branch prediction while preserving compatibility, but surfaced issues with production programs that were difficult to solve without increasing verifier complexity. A more complete discussion of issues and fixes is available at [2]. Fix this by maintaining an explicit list of tracepoints where the arguments are known to be NULL, and mark the positional arguments as PTR_MAYBE_NULL. Additionally, capture the tracepoints where arguments are known to be ERR_PTR, and mark these arguments as scalar values to prevent potential dereference. Each hex digit is used to encode NULL-ness (0x1) or ERR_PTR-ness (0x2), shifted by the zero-indexed argument number x 4. This can be represented as follows: 1st arg: 0x1 2nd arg: 0x10 3rd arg: 0x100 ... and so on (likewise for ERR_PTR case). In the future, an automated pass will be used to produce such a list, or insert __nullable annotations automatically for tracepoints. Each compilation unit will be analyzed and results will be collated to find whether a tracepoint pointer is definitely not null, maybe null, or an unknown state where verifier conservatively marks it PTR_MAYBE_NULL. A proof of concept of this tool from Eduard is available at [3]. Note that in case we don't find a specification in the raw_tp_null_args array and the tracepoint belongs to a kernel module, we will conservatively mark the arguments as PTR_MAYBE_NULL. This is because unlike for in-tree modules, out-of-tree module tracepoints may pass NULL freely to the tracepoint. We don't protect against such tracepoints passing ERR_PTR (which is uncommon anyway), lest we mark all such arguments as SCALAR_VALUE. While we are it, let's adjust the test raw_tp_null to not perform dereference of the skb->mark, as that won't be allowed anymore, and make it more robust by using inline assembly to test the dead code elimination behavior, which should still stay the same.

KVM: x86: Cache CPUID.0xD XSTATE offsets+sizes during module init
Snapshot the output of CPUID.0xD.[1..n] during kvm.ko initiliaization to avoid the overead of CPUID during runtime. The offset, size, and metadata for CPUID.0xD.[1..n] sub-leaves does not depend on XCR0 or XSS values, i.e. is constant for a given CPU, and thus can be cached during module load. On Intel's Emerald Rapids, CPUID is *wildly* expensive, to the point where recomputing XSAVE offsets and sizes results in a 4x increase in latency of nested VM-Enter and VM-Exit (nested transitions can trigger xstate_required_size() multiple times per transition), relative to using cached values. The issue is easily visible by running `perf top` while triggering nested transitions: kvm_update_cpuid_runtime() shows up at a whopping 50%. As measured via RDTSC from L2 (using KVM-Unit-Test's CPUID VM-Exit test and a slightly modified L1 KVM to handle CPUID in the fastpath), a nested roundtrip to emulate CPUID on Skylake (SKX), Icelake (ICX), and Emerald Rapids (EMR) takes: SKX 11650 ICX 22350 EMR 28850 Using cached values, the latency drops to: SKX 6850 ICX 9000 EMR 7900 The underlying issue is that CPUID itself is slow on ICX, and comically slow on EMR. The problem is exacerbated on CPUs which support XSAVES and/or XSAVEC, as KVM invokes xstate_required_size() twice on each runtime CPUID update, and because there are more supported XSAVE features (CPUID for supported XSAVE feature sub-leafs is significantly slower). SKX: CPUID.0xD.2 = 348 cycles CPUID.0xD.3 = 400 cycles CPUID.0xD.4 = 276 cycles CPUID.0xD.5 = 236 cycles <other sub-leaves are similar> EMR: CPUID.0xD.2 = 1138 cycles CPUID.0xD.3 = 1362 cycles CPUID.0xD.4 = 1068 cycles CPUID.0xD.5 = 910 cycles CPUID.0xD.6 = 914 cycles CPUID.0xD.7 = 1350 cycles CPUID.0xD.8 = 734 cycles CPUID.0xD.9 = 766 cycles CPUID.0xD.10 = 732 cycles CPUID.0xD.11 = 718 cycles CPUID.0xD.12 = 734 cycles CPUID.0xD.13 = 1700 cycles CPUID.0xD.14 = 1126 cycles CPUID.0xD.15 = 898 cycles CPUID.0xD.16 = 716 cycles CPUID.0xD.17 = 748 cycles CPUID.0xD.18 = 776 cycles Note, updating runtime CPUID information multiple times per nested transition is itself a flaw, especially since CPUID is a mandotory intercept on both Intel and AMD. E.g. KVM doesn't need to ensure emulated CPUID state is up-to-date while running L2. That flaw will be fixed in a future patch, as deferring runtime CPUID updates is more subtle than it appears at first glance, the benefits aren't super critical to have once the XSAVE issue is resolved, and caching CPUID output is desirable even if KVM's updates are deferred.

block: Fix potential deadlock while freezing queue and acquiring sysfs_lock
For storing a value to a queue attribute, the queue_attr_store function
first freezes the queue (->q_usage_counter(io)) and then acquire
->sysfs_lock. This seems not correct as the usual ordering should be to
acquire ->sysfs_lock before freezing the queue. This incorrect ordering
causes the following lockdep splat which we are able to reproduce always
simply by accessing /sys/kernel/debug file using ls command:

Prevent the above lockdep warning by acquiring ->sysfs_lock before
freezing the queue while storing a queue attribute in queue_attr_store
function. Later, we also found[1] another function __blk_mq_update_nr_
hw_queues where we first freeze queue and then acquire the ->sysfs_lock.
So we've also updated lock ordering in __blk_mq_update_nr_hw_queues
function and ensured that in all code paths we follow the correct lock
ordering i.e. acquire ->sysfs_lock before freezing the queue.

irqchip/gic-v3: Work around insecure GIC integrations
It appears that the relatively popular RK3399 SoC has been put together using a large amount of illicit substances, as experiments reveal that its integration of GIC500 exposes the *secure* programming interface to non-secure. This has some pretty bad effects on the way priorities are handled, and results in a dead machine if booting with pseudo-NMI enabled (irqchip.gicv3_pseudo_nmi=1) if the kernel contains |

irqchip/gic: Correct declaration of *percpu_base pointer in union gic_base
percpu_base is used in various percpu functions that expect variable in __percpu address space. Correct the declaration of percpu_base to void __iomem * __percpu *percpu_base; to declare the variable as __percpu pointer. The patch fixes several sparse warnings: irq-gic.c:1172:44: warning: incorrect type in assignment (different address spaces) irq-gic.c:1172:44: expected void [noderef] __percpu *[noderef] __iomem *percpu_base irq-gic.c:1172:44: got void [noderef] __iomem *[noderef] __percpu * ... irq-gic.c:1231:43: warning: incorrect type in argument 1 (different address spaces) irq-gic.c:1231:43: expected void [noderef] __percpu *__pdata irq-gic.c:1231:43: got void [noderef] __percpu *[noderef] __iomem *percpu_base There were no changes in the resulting object files.
