arm32, bpf: add support for 64 bit division instruction
ARM32 doesn't have instructions to do 64-bit/64-bit divisions. So, to implement the following instructions: BPF_ALU64 | BPF_DIV BPF_ALU64 | BPF_MOD BPF_ALU64 | BPF_SDIV BPF_ALU64 | BPF_SMOD We implement the above instructions by doing function calls to div64_u64() and div64_u64_rem() for unsigned division/mod and calls to div64_s64() for signed division/mod.

arm32, bpf: add support for 32-bit signed division
The cpuv4 added a new BPF_SDIV instruction that does signed division. The encoding is similar to BPF_DIV but BPF_SDIV sets offset=1. ARM32 already supports 32-bit BPF_DIV which can be easily extended to support BPF_SDIV as ARM32 has the SDIV instruction. When the CPU is not ARM-v7, we implement that SDIV/SMOD with the function call similar to the implementation of DIV/MOD.

arm32, bpf: add support for unconditional bswap instruction
The cpuv4 added a new unconditional bswap instruction with following behaviour: BPF_ALU64 | BPF_TO_LE | BPF_END with imm = 16/32/64 means: dst = bswap16(dst) dst = bswap32(dst) dst = bswap64(dst) As we already support converting to big-endian from little-endian we can use the same for unconditional bswap. just treat the unconditional scenario the same as big-endian conversion.

arm32, bpf: add support for sign-extension mov instruction
The cpuv4 added a new BPF_MOVSX instruction that sign extends the src before moving it to the destination. BPF_ALU | BPF_MOVSX sign extends 8-bit and 16-bit operands into 32-bit operands, and zeroes the remaining upper 32 bits. BPF_ALU64 | BPF_MOVSX sign extends 8-bit, 16-bit, and 32-bit operands into 64-bit operands. The offset field of the instruction is used to tell the number of bit to use for sign-extension. BPF_MOV and BPF_MOVSX have the same code but the former sets offset to 0 and the later one sets the offset to 8, 16 or 32 The behaviour of this instruction is dst = (s8,s16,s32)src On ARM32 the implementation uses LSH and ARSH to extend the 8/16 bits to a 32-bit register and then it is sign extended to the upper 32-bit register using ARSH. For 32-bit we just move it to the destination register and use ARSH to extend it to the upper 32-bit register.

arm32, bpf: add support for sign-extension load instruction
The cpuv4 added the support of an instruction that is similar to load but also sign-extends the result after the load. BPF_MEMSX | <size> | BPF_LDX means dst = *(signed size *) (src + offset) here <size> can be one of BPF_B, BPF_H, BPF_W. ARM32 has instructions to load a byte or a half word with sign extension into a 32bit register. As the JIT uses two 32 bit registers to simulate a 64-bit BPF register, an extra instruction is emitted to sign-extent the result up to the second register.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"ARM:
- Clean up vCPU targets, always returning generic v8 as the preferred
target
- Trap forwarding infrastructure for nested virtualization (used for
traps that are taken from an L2 guest and are needed by the L1
hypervisor)
- FEAT_TLBIRANGE support to only invalidate specific ranges of
addresses when collapsing a table PTE to a block PTE. This avoids
that the guest refills the TLBs again for addresses that aren't
covered by the table PTE.
- Fix vPMU issues related to handling of PMUver.
- Don't unnecessary align non-stack allocations in the EL2 VA space
- Drop HCR_VIRT_EXCP_MASK, which was never used...
- Don't use smp_processor_id() in kvm_arch_vcpu_load(), but the cpu
parameter instead
- Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
- Remove prototypes without implementations
RISC-V:
- Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
- Added ONE_REG interface for SATP mode
- Added ONE_REG interface to enable/disable multiple ISA extensions
- Improved error codes returned by ONE_REG interfaces
- Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
- Added get-reg-list selftest for KVM RISC-V
s390:
- PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
- Guest debug fixes (Ilya)
x86:
- Clean up KVM's handling of Intel architectural events
- Intel bugfixes
- Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use
debug registers and generate/handle #DBs
- Clean up LBR virtualization code
- Fix a bug where KVM fails to set the target pCPU during an IRTE
update
- Fix fatal bugs in SEV-ES intrahost migration
- Fix a bug where the recent (architecturally correct) change to
reinject #BP and skip INT3 broke SEV guests (can't decode INT3 to
skip it)
- Retry APIC map recalculation if a vCPU is added/enabled
- Overhaul emergency reboot code to bring SVM up to par with VMX, tie
the "emergency disabling" behavior to KVM actually being loaded,
and move all of the logic within KVM
- Fix user triggerable WARNs in SVM where KVM incorrectly assumes the
TSC ratio MSR cannot diverge from the default when TSC scaling is
disabled up related code
- Add a framework to allow "caching" feature flags so that KVM can
check if the guest can use a feature without needing to search
guest CPUID
- Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
- Fix KVM's handling of !visible guest roots to avoid premature
triple fault injection
- Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the
API surface that is needed by external users (currently only
KVMGT), and fix a variety of issues in the process
Generic:
- Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier
events to pass action specific data without needing to constantly
update the main handlers.
- Drop unused function declarations
Selftests:
- Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
- Add support for printf() in guest code and covert all guest asserts
to use printf-based reporting
- Clean up the PMU event filter test and add new testcases
- Include x86 selftests in the KVM x86 MAINTAINERS entry"

Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment.

CET consists of two related security features: shadow stacks and indirect branch tracking. This series implements just the shadow stack part of this feature, and just for userspace. The main use case for shadow stack is providing protection against return oriented programming attacks. It works by maintaining a secondary (shadow) stack using a special memory type that has protections against modification. When executing a CALL instruction, the processor pushes the return address to both the normal stack and to the special permission shadow stack. Upon RET, the processor pops the shadow stack copy and compares it to the normal stack copy.

Merge tag 'v6.6-vfs.fchmodat2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull fchmodat2 system call from Christian Brauner: "This adds the fchmodat2() system call. It is a revised version of the fchmodat() system call, adding a missing flag argument. Support for both AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH are included. Adding this system call revision has been a longstanding request but so far has always fallen through the cracks. While the kernel implementation of fchmodat() does not have a flag argument the libc provided POSIX-compliant fchmodat(3) version does. Both glibc and musl have to implement a workaround in order to support AT_SYMLINK_NOFOLLOW (see [1] and [2]). The workaround is brittle because it relies not just on O_PATH and O_NOFOLLOW semantics and procfs magic links but also on our rather inconsistent symlink semantics. This gives userspace a proper fchmodat2() system call that libcs can use to properly implement fchmodat(3) and allows them to get rid of their hacks. In this case it will immediately benefit them as the current workaround is already defunct because of aformentioned inconsistencies. In addition to AT_SYMLINK_NOFOLLOW, give userspace the ability to use AT_EMPTY_PATH with fchmodat2(). This is already possible with fchownat() so there's no reason to not also support it for fchmodat2(). The implementation is simple and comes with selftests. Implementation of the system call and wiring up the system call are done as separate patches even though they could arguably be one patch. But in case there are merge conflicts from other system call additions it can be beneficial to have separate patches" Link: https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/fchmodat.c;h=17eca54051ee28ba1ec3f9aed170a62630959143;hb=a492b1e5ef7ab50c6fdd4e4e9879ea5569ab0a6c#l35 [1] Link: https://git.musl-libc.org/cgit/musl/tree/src/stat/fchmodat.c?id=718f363bc2067b6487900eddc9180c84e7739f80#n28 [2] * tag 'v6.6-vfs.fchmodat2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests: fchmodat2: remove duplicate unneeded defines fchmodat2: add support for AT_EMPTY_PATH selftests: Add fchmodat2 selftest arch: Register fchmodat2, usually as syscall 452 fs: Add fchmodat2() Non-functional cleanup of a "__user * filename" |

arm: implement the new page table range API
Add set_ptes(), update_mmu_cache_range(), flush_dcache_folio() and flush_icache_pages(). Change the PG_dcache_clear flag from being per-page to per-folio which makes __dma_page_dev_to_cpu() a bit more exciting.

minmax: add in_range() macro
Patch series "New page table range API", v6.
This patchset changes the API used by the MM to set up page table entries.
The four APIs are:
set_ptes(mm, addr, ptep, pte, nr)
update_mmu_cache_range(vma, addr, ptep, nr)
flush_dcache_folio(folio)
flush_icache_pages(vma, page, nr)
flush_dcache_folio() isn't technically new, but no architecture
implemented it, so I've done that for them. The old APIs remain around
but are mostly implemented by calling the new interfaces.
The new APIs are based around setting up N page table entries at once.
The N entries belong to the same PMD, the same folio and the same VMA, so
ptep++ is a legitimate operation, and locking is taken care of for you.
Some architectures can do a better job of it than just a loop, but I have
hesitated to make too deep a change to architectures I don't understand
well.
One thing I have changed in every architecture is that PG_arch_1 is now a
per-folio bit instead of a per-page bit when used for dcache clean/dirty
tracking. This was something that would have to happen eventually, and it
makes sense to do it now rather than iterate over every page involved in a
cache flush and figure out if it needs to happen.
The point of all this is better performance, and Fengwei Yin has measured
improvement on x86. I suspect you'll see improvement on your architecture
too. Try the new will-it-scale test mentioned here:
https://lore.kernel.org/linux-mm/20230206140639.538867-5-fengwei.yin@intel.com/
You'll need to run it on an XFS filesystem and have
CONFIG_TRANSPARENT_HUGEPAGE set.
This patchset is the basis for much of the anonymous large folio work
being done by Ryan, so it's received quite a lot of testing over the last
few months.
This patch (of 38):
Determine if a value lies within a range more efficiently (subtraction +
comparison vs two comparisons and an AND). It also has useful (under some
circumstances) behaviour if the range exceeds the maximum value of the
type. Convert all the conflicting definitions of in_range() within the
kernel; some can use the generic definition while others need their own
definition.

KVM: arm64: pmu: Resync EL0 state on counter rotation
Huang Shijie reports that, when profiling a guest from the host with a number of events that exceeds the number of available counters, the reported counts are wildly inaccurate. Without the counter oversubscription, the reported counts are correct. Their investigation indicates that upon counter rotation (which takes place on the back of a timer interrupt), we fail to re-apply the guest EL0 enabling, leading to the counting of host events instead of guest events. In order to solve this, add yet another hook between the host PMU driver and KVM, re-applying the guest EL0 configuration if the right conditions apply (the host is VHE, we are in interrupt context, and we interrupted a running vcpu). This triggers a new vcpu request which will apply the correct configuration on guest reentry. With this, we have the correct counts, even when the counters are oversubscribed.

arm: include asm/cacheflush.h in asm/hugetlb.h
Patch series "arch: include asm/cacheflush.h in asm/hugetlb.h". Three architectures are using PG_dcache_clean in their asm/hugetlb.h, but relying on accident to include the asm/cacheflush.h which defines it. This patch (of 3): PG_dcache_clean is used in asm/hugetlb.h but defined in asm/cacheflush.h: builds rely on an accident of that being included via linux/mempolicy.h, but better include it directly (like arch/sh/include/asm/hugetlb.h does).

arm: convert various functions to use ptdescs
As part of the conversions to replace pgtable constructor/destructors with ptdesc equivalents, convert various page table functions to use ptdescs. late_alloc() also uses the __get_free_pages() helper function. Convert this to use pagetable_alloc() and ptdesc_address() instead to help standardize page tables further.

nmi_backtrace: allow excluding an arbitrary CPU
The APIs that allow backtracing across CPUs have always had a way to exclude the current CPU. This convenience means callers didn't need to find a place to allocate a CPU mask just to handle the common case. Let's extend the API to take a CPU ID to exclude instead of just a boolean. This isn't any more complex for the API to handle and allows the hardlockup detector to exclude a different CPU (the one it already did a trace for) without needing to find space for a CPU mask. Arguably, this new API also encourages safer behavior. Specifically if the caller wants to avoid tracing the current CPU (maybe because they already traced the current CPU) this makes it more obvious to the caller that they need to make sure that the current CPU ID can't change.

arm: adjust_pte() use pte_offset_map_nolock()
Instead of pte_lockptr(), use the recently added pte_offset_map_nolock() in adjust_pte(): because it gives the not-locked ptl for precisely that pte, which the caller can then safely lock; whereas pte_lockptr() is not so tightly coupled, because it dereferences the pmd pointer again.

hw_breakpoint: fix single-stepping when using bpf_overflow_handler
Arm platforms use is_default_overflow_handler() to determine if the
hw_breakpoint code should single-step over the breakpoint trigger or
let the custom handler deal with it.
Since bpf_overflow_handler() currently isn't recognized as a default
handler, attaching a BPF program to a PERF_TYPE_BREAKPOINT event causes
it to keep firing (the instruction triggering the data abort exception
is never skipped). For example:
# bpftrace -e 'watchpoint:0x10000:4:w { print("hit") }' -c ./test
Attaching 1 probe...
hit
hit
[...]
^C
(./test performs a single 4-byte store to 0x10000)
This patch replaces the check with uses_default_overflow_handler(),
which accounts for the bpf_overflow_handler() case by also testing
if one of the perf_event_output functions gets invoked indirectly,
via orig_default_handler.
