2025-02-09KVM: arm64: Simplify np-guest hypercallsQuentin Perret
When the handling of a guest stage-2 permission fault races with an MMU notifier, the faulting page might be gone from the guest's stage-2 by the point we attempt to call (p)kvm_pgtable_stage2_relax_perms(). In the normal KVM case, this leads to returning -EAGAIN which user_mem_abort() handles correctly by simply re-entering the guest. However, the pKVM hypercall implementation has additional logic to check the page state using __check_host_shared_guest() which gets confused with absence of a page mapped at the requested IPA and returns -ENOENT, hence breaking user_mem_abort() and hilarity ensues. Luckily, several of the hypercalls for managing the stage-2 page-table of NP guests have no effect on the pKVM ownership tracking (wrprotect, test_clear_young, mkyoung, and crucially relax_perms), so the extra state checking logic is in fact not strictly necessary. So, to fix the discrepancy between standard KVM and pKVM, let's just drop the superfluous __check_host_shared_guest() logic from those hypercalls and make the extra state checking a debug assertion dependent on CONFIG_NVHE_EL2_DEBUG as we already do for other transitions.

2025-02-09KVM: arm64: Improve error handling from check_host_shared_guest()Quentin Perret
The check_host_shared_guest() path expects to find a last-level valid PTE in the guest's stage-2 page-table. However, it checks the PTE's level before its validity, which makes it hard for callers to figure out what went wrong. To make error handling simpler, check the PTE's validity first.

Remove 32-bit support from the fast path in xts_crypt(). Then optimize it for 64-bit, and simplify the code, by switching to sg_virt() and removing the now-unnecessary checks for crossing a page boundary. The result is simpler code that is slightly smaller and faster in the case that actually matters (64-bit).

2025-02-08crypto: crct10dif - remove from crypto APIEric Biggers
Remove the "crct10dif" shash algorithm from the crypto API. It has no known user now that the lib is no longer built on top of it. It has no remaining references in kernel code. The only other potential users would be the usual components that allow specifying arbitrary hash algorithms by name, namely AF_ALG and dm-integrity. However there are no indications that "crct10dif" is being used with these components. Debian Code Search and web searches don't find anything relevant, and explicitly grepping the source code of the usual suspects (cryptsetup, libell, iwd) finds no matches either. "crc32" and "crc32c" are used in a few more places, but that doesn't seem to be the case for "crct10dif". crc_t10dif_update() is also tested by crc_kunit now, so the test coverage provided via the crypto self-tests is no longer needed. Also note that the "crct10dif" shash algorithm was inconsistent with the rest of the shash API in that it wrote the digest in CPU endianness, making the resulting byte array differ on little endian vs. big endian platforms. This means it was effectively just built for use by the lib functions, and it was not actually correct to treat it as "just another hash function" that could be dropped in via the shash API.

2025-02-08perf/x86/intel: Ensure LBRs are disabled when a CPU is startingSean Christopherson
Explicitly clear DEBUGCTL.LBR when a CPU is starting, prior to purging the LBR MSRs themselves, as at least one system has been found to transfer control to the kernel with LBRs enabled (it's unclear whether it's a BIOS flaw or a CPU goof). Because the kernel preserves the original DEBUGCTL, even when toggling LBRs, leaving DEBUGCTL.LBR as is results in running with LBRs enabled at all times.

2025-02-08perf/x86/intel: Fix ARCH_PERFMON_NUM_COUNTER_LEAFKan Liang
The EAX of the CPUID Leaf 023H enumerates the mask of valid sub-leaves. To tell the availability of the sub-leaf 1 (enumerate the counter mask), perf should check the bit 1 (0x2) of EAS, rather than bit 0 (0x1). The error is not user-visible on bare metal. Because the sub-leaf 0 and the sub-leaf 1 are always available. However, it may bring issues in a virtualization environment when a VMM only enumerates the sub-leaf 0. Introduce the cpuid35_e?x to replace the macros, which makes the implementation style consistent.

The PEBS-via-PT feature is exposed for the e-core of some hybrid platforms, e.g., ADL and MTL. But it never works. $ dmesg | grep PEBS [ 1.793888] core: cpu_atom PMU driver: PEBS-via-PT $ perf record -c 1000 -e '{intel_pt/branch=0/, cpu_atom/cpu-cycles,aux-output/pp}' -C8 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_atom/cpu-cycles,aux-output/pp). "dmesg | grep -i perf" may provide additional information. The "PEBS-via-PT" is printed if the corresponding bit of per-PMU capabilities is set. Since the feature is supported by the e-core HW, perf sets the bit for e-core. However, for Intel PT, if a feature is not supported on all CPUs, it is not supported at all. The PEBS-via-PT event cannot be created successfully. The PEBS-via-PT is no longer enumerated on the latest hybrid platform. It will be deprecated on future platforms with Arch PEBS.

Not even the 10 remaining Alpha users. In [2] it was pointed out that parts of setarch weren't working properly on alpha because it has it's own SET_PERSONALITY implementation. In the discussion that followed Richard Henderson pointed out that the 32bit pointer support for alpha was never completed. Fix this by removing alpha's 32bit pointer support.

2025-02-06arm64: dts: mediatek: add support for MT8370 SoCLouis-Alexis Eyraud
Add the support of the Mediatek MT8370 SoC, a less powerful variant of MT8390 SoC. Their main differences are: - Arm Cortex-A55 cores number (4 vs 6) - Arm Cortex-A78 core speed (2.0 GHz vs 2.2 Ghz) - Arm Mali-G57 GPU core number (2 vs 3) Like MT8390, MT8370 hardware register maps are identical to MT8188. Note: The devicetree for MT8370 SoC does not currently contain the needed overrides to support the Mali GPU integrated into this SoC. This is scheduled to be done with a later change.

2025-02-05s390/net: Remove LCS driverAswin Karuvally
The original Open Systems Adapter (OSA) was introduced by IBM in the mid-90s. These were then superseded by OSA-Express in 1999 which used Queued Direct IO to greatly improve throughput. The newer cards retained the older, slower non-QDIO (OSE) modes for compatibility with older systems. In Linux, the lcs driver was responsible for cards operating in the older OSE mode and the qeth driver was introduced to allow the OSA-Express cards to operate in the newer QDIO (OSD) mode. For an S390 machine from 1998 or later, there is no reason to use the OSE mode and lcs driver as all OSA cards since 1999 provide the faster OSD mode. As a result, it's been years since we have heard of a customer configuration involving the lcs driver. This patch removes the lcs driver. The technology it supports has been obsolete for past 25+ years and is irrelevant for current use cases.

2025-02-05x86: Compare physical instead of virtual PGD addressesMaciej Wieczor-Retman
This is a preparatory patch for when pointers have tags in their upper address bits. But it's a harmless change on its own. The mm->pgd virtual address may be tagged because it came out of the allocator at some point. The __va(read_cr3_pa()) address will never be tagged (the tag bits are all 1's). A direct pointer value comparison would fail if one is tagged and the other is not. To fix this, just compare the physical addresses which are never affected by tagging.

2025-02-05x86/smp: Eliminate mwait_play_dead_cpuid_hint()Patryk Wlazlyn
Currently, mwait_play_dead_cpuid_hint() looks up the MWAIT hint of the deepest idle state by inspecting CPUID leaf 0x5 with the assumption that, if the number of sub-states for a given major C-state is nonzero, those sub-states are always represented by consecutive numbers starting from 0. This assumption is not based on the documented platform behavior and in fact it is not met on recent Intel platforms. For example, Intel's Sierra Forest report two C-states with two substates each in cpuid leaf 0x5: Name* target cstate target subcstate (mwait hint) =========================================================== C1 0x00 0x00 C1E 0x00 0x01 -- 0x10 ---- C6S 0x20 0x22 C6P 0x20 0x23 -- 0x30 ---- /* No more (sub)states all the way down to the end. */ =========================================================== * Names of the cstates are not included in the CPUID leaf 0x5, they are taken from the product specific documentation. Notice that hints 0x20 and 0x21 are not defined for C-state 0x20 (C6), so the existing MWAIT hint lookup in mwait_play_dead_cpuid_hint() based on the CPUID leaf 0x5 contents does not work in this case. Instead of using MWAIT hint lookup that is not guaranteed to work, make native_play_dead() rely on the idle driver for the given platform to put CPUs going offline into appropriate idle state and, if that fails, fall back to hlt_play_dead(). Accordingly, drop mwait_play_dead_cpuid_hint() altogether and make native_play_dead() call cpuidle_play_dead() instead of it unconditionally with the assumption that it will not return if it is successful. Still, in case cpuidle_play_dead() fails, call hlt_play_dead() at the end.
