[PATCH OLK-6.6] ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback
by Qi Xi 15 Apr '25

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> mainline inclusion from mainline-v6.14-rc1 commit 301c26a018acb94dd537a4418cefa0f654500c6f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3 CVE: CVE-2024-58077 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.

[PATCH OLK-6.6 1/8] objtool: Fix C jump table annotations for Clang
by Hongchen Zhang 15 Apr '25

15 Apr '25

From: Ard Biesheuvel <ardb(a)kernel.org> mainline inclusion from mainline-v6.14-rc5 commit 73cfc53cc3b6380eccf013049574485f64cb83ca category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC10DU CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- A C jump table (such as the one used by the BPF interpreter) is a const global array of absolute code addresses, and this means that the actual values in the table may not be known until the kernel is booted (e.g., when using KASLR or when the kernel VA space is sized dynamically). When using PIE codegen, the compiler will default to placing such const global objects in .data.rel.ro (which is annotated as writable), rather than .rodata (which is annotated as read-only). As C jump tables are explicitly emitted into .rodata, this used to result in warnings for LoongArch builds (which uses PIE codegen for the entire kernel) like Warning: setting incorrect section attributes for .rodata..c_jump_table due to the fact that the explicitly specified .rodata section inherited the read-write annotation that the compiler uses for such objects when using PIE codegen. This warning was suppressed by explicitly adding the read-only annotation to the __attribute__((section(""))) string, by commit c5b1184decc8 ("compiler.h: specify correct attribute for .rodata..c_jump_table") Unfortunately, this hack does not work on Clang's integrated assembler, which happily interprets the appended section type and permission specifiers as part of the section name, which therefore no longer matches the hard-coded pattern '.rodata..c_jump_table' that objtool expects, causing it to emit a warning kernel/bpf/core.o: warning: objtool: ___bpf_prog_run+0x20: sibling call from callable instruction with modified stack frame Work around this, by emitting C jump tables into .data.rel.ro instead, which is treated as .rodata by the linker script for all builds, not just PIE based ones.

[PATCH OLK-6.6 0/2] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 15 Apr '25

15 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.

[PATCH OLK-6.6 0/2] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 15 Apr '25

15 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.

[PATCH OLK-6.6] perf arm64: kprobe: Enable OPTPROBE for arm64
by Yushan Wang 14 Apr '25

14 Apr '25

From: Qinxin Xia <xiaqinxin(a)huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC0ZB4 ---------------------------------------------------------------------- This patch introduce optprobe for ARM64. In optprobe, probed instruction is replaced by a branch instruction to trampoline. Performance of optprobe on Hip08 platform is test using kprobe example module to analyze the latency of a kernel function, and here is the result: common kprobe: [280709.846380] do_empty returned 0 and took 1530 ns to execute [280709.852057] do_empty returned 0 and took 550 ns to execute [280709.857631] do_empty returned 0 and took 440 ns to execute [280709.863215] do_empty returned 0 and took 380 ns to execute [280709.868787] do_empty returned 0 and took 360 ns to execute [280709.874362] do_empty returned 0 and took 340 ns to execute [280709.879936] do_empty returned 0 and took 320 ns to execute [280709.885505] do_empty returned 0 and took 300 ns to execute [280709.891075] do_empty returned 0 and took 280 ns to execute [280709.896646] do_empty returned 0 and took 290 ns to execute optprobe: [ 2965.964572] do_empty returned 0 and took 90 ns to execute [ 2965.969952] do_empty returned 0 and took 80 ns to execute [ 2965.975332] do_empty returned 0 and took 70 ns to execute [ 2965.980714] do_empty returned 0 and took 60 ns to execute [ 2965.986128] do_empty returned 0 and took 80 ns to execute [ 2965.991507] do_empty returned 0 and took 70 ns to execute [ 2965.996884] do_empty returned 0 and took 70 ns to execute [ 2966.002262] do_empty returned 0 and took 80 ns to execute [ 2966.007642] do_empty returned 0 and took 70 ns to execute [ 2966.013020] do_empty returned 0 and took 70 ns to execute [ 2966.018400] do_empty returned 0 and took 70 ns to execute As the result shows, optprobe can greatly reduce the latency. Big latency of common kprobe will significantly impact the real result while doing performance analysis or debugging performance issues in lab, so optprobe is useful in this scenario. The trampoline design is illustrated in the following diagram. Some commands will be replaced in arch_prepare_optimized_kprobe. +------------------optprobe_template_entry---------------------+ |- Saving stacks and registers | |- Loading params for callback | +------------------optprobe_template_common--------------------+ |- nop | |(replaced to the branch jump to optprobe_common) | |- Restore stacks and registers | +-------------optprobe_template_restore_orig_insn--------------+ |- nop | |(replaced to the kprobe->opcode) | +----------------optprobe_template_restore_end-----------------+ |- nop | |(replaced to next address of the probe point) | +------------------optprobe_template_val-----------------------+ |- 0 (two 32-bit words) | |(replaced to params for optprobe_optimized_callback) | +-----------------optprobe_template_orig_addr------------------+ |- 0 (two 32-bit words) | |(replaced to origin probe point address) | +-------------------optprobe_template_end----------------------+ |- nop | +--------------------------------------------------------------+ Co-developed-by: Qi Liu <liuqi115(a)huawei.com> Signed-off-by: Qi Liu <liuqi115(a)huawei.com> Signed-off-by: Qinxin Xia <xiaqinxin(a)huawei.com> Signed-off-by: Qizhi Zhang <zhangqizhi3(a)h-partners.com> Signed-off-by: Yushan Wang <wangyushan12(a)huawei.com> --- arch/arm64/Kconfig | 1 + arch/arm64/include/asm/kprobes.h | 22 ++ arch/arm64/kernel/probes/Makefile | 2 + arch/arm64/kernel/probes/opt_arm64.c | 243 ++++++++++++++++++ .../arm64/kernel/probes/optprobe_trampoline.S | 113 ++++++++ 5 files changed, 381 insertions(+) create mode 100644 arch/arm64/kernel/probes/opt_arm64.c create mode 100644 arch/arm64/kernel/probes/optprobe_trampoline.S diff --git a/arch/arm64/Kconfig b/arch/arm64/Kconfig index 9da9d58f1c02..194051628457 100644 --- a/arch/arm64/Kconfig +++ b/arch/arm64/Kconfig @@ -240,6 +240,7 @@ config ARM64 select HAVE_SYSCALL_TRACEPOINTS select HAVE_KPROBES select HAVE_KRETPROBES + select HAVE_OPTPROBES select HAVE_GENERIC_VDSO select HOTPLUG_CORE_SYNC_DEAD if HOTPLUG_CPU select HOTPLUG_SMT if (SMP && HOTPLUG_CPU) diff --git a/arch/arm64/include/asm/kprobes.h b/arch/arm64/include/asm/kprobes.h index 05cd82eeca13..e4972645a381 100644 --- a/arch/arm64/include/asm/kprobes.h +++ b/arch/arm64/include/asm/kprobes.h @@ -39,6 +39,28 @@ void arch_remove_kprobe(struct kprobe *);

[PATCH OLK-6.6] KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state
by Huang Xiaojia 14 Apr '25

14 Apr '25

From: Mark Rutland <mark.rutland(a)arm.com> stable inclusion from stable-v6.12.21 commit 79e140bba70bcacc5fe15bf8c0b958793fd7d56f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBZH7N CVE: CVE-2025-22013 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fbc7e61195e23f744814e78524b73b59faa54ab4 ] There are several problems with the way hyp code lazily saves the host's FPSIMD/SVE state, including: * Host SVE being discarded unexpectedly due to inconsistent configuration of TIF_SVE and CPACR_ELx.ZEN. This has been seen to result in QEMU crashes where SVE is used by memmove(), as reported by Eric Auger: https://issues.redhat.com/browse/RHEL-68997 * Host SVE state is discarded *after* modification by ptrace, which was an unintentional ptrace ABI change introduced with lazy discarding of SVE state. * The host FPMR value can be discarded when running a non-protected VM, where FPMR support is not exposed to a VM, and that VM uses FPSIMD/SVE. In these cases the hyp code does not save the host's FPMR before unbinding the host's FPSIMD/SVE/SME state, leaving a stale value in memory. Avoid these by eagerly saving and "flushing" the host's FPSIMD/SVE/SME state when loading a vCPU such that KVM does not need to save any of the host's FPSIMD/SVE/SME state. For clarity, fpsimd_kvm_prepare() is removed and the necessary call to fpsimd_save_and_flush_cpu_state() is placed in kvm_arch_vcpu_load_fp(). As 'fpsimd_state' and 'fpmr_ptr' should not be used, they are set to NULL; all uses of these will be removed in subsequent patches. Historical problems go back at least as far as v5.17, e.g. erroneous assumptions about TIF_SVE being clear in commit: 8383741ab2e773a9 ("KVM: arm64: Get rid of host SVE tracking/saving") ... and so this eager save+flush probably needs to be backported to ALL stable trees. Fixes: 93ae6b01bafee8fa ("KVM: arm64: Discard any SVE state when entering KVM guests") Fixes: 8c845e2731041f0f ("arm64/sve: Leave SVE enabled on syscall if we don't context switch") Fixes: ef3be86021c3bdf3 ("KVM: arm64: Add save/restore support for FPMR") Reported-by: Eric Auger <eauger(a)redhat.com> Reported-by: Wilco Dijkstra <wilco.dijkstra(a)arm.com> Reviewed-by: Mark Brown <broonie(a)kernel.org> Tested-by: Mark Brown <broonie(a)kernel.org> Tested-by: Eric Auger <eric.auger(a)redhat.com> Acked-by: Will Deacon <will(a)kernel.org> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Florian Weimer <fweimer(a)redhat.com> Cc: Fuad Tabba <tabba(a)google.com> Cc: Jeremy Linton <jeremy.linton(a)arm.com> Cc: Marc Zyngier <maz(a)kernel.org> Cc: Oliver Upton <oliver.upton(a)linux.dev> Cc: Paolo Bonzini <pbonzini(a)redhat.com> Signed-off-by: Mark Rutland <mark.rutland(a)arm.com> Reviewed-by: Oliver Upton <oliver.upton(a)linux.dev> Link: https://lore.kernel.org/r/20250210195226.1215254-2-mark.rutland@arm.com Signed-off-by: Marc Zyngier <maz(a)kernel.org> [ Mark: Handle vcpu/host flag conflict ] Signed-off-by: Mark Rutland <mark.rutland(a)arm.com> Signed-off-by: Mark Brown <broonie(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Conflicts: arch/arm64/kvm/fpsimd.c [Lack of commit ef3be86021c3bdf384c36d9d4aa1ee9fe65b95af] Signed-off-by: Huang Xiaojia <huangxiaojia2(a)huawei.com> --- arch/arm64/kernel/fpsimd.c | 25 ------------------------- arch/arm64/kvm/fpsimd.c | 33 +++++++++------------------------ 2 files changed, 9 insertions(+), 49 deletions(-) diff --git a/arch/arm64/kernel/fpsimd.c b/arch/arm64/kernel/fpsimd.c index 0137d987631e..bd4f6c6ee0f3 100644 --- a/arch/arm64/kernel/fpsimd.c +++ b/arch/arm64/kernel/fpsimd.c @@ -1707,31 +1707,6 @@ void fpsimd_signal_preserve_current_state(void) sve_to_fpsimd(current); } -/* - * Called by KVM when entering the guest. - */ -void fpsimd_kvm_prepare(void) -{ - if (!system_supports_sve()) - return; - - /* - * KVM does not save host SVE state since we can only enter - * the guest from a syscall so the ABI means that only the - * non-saved SVE state needs to be saved.

[PATCH OLK-6.6] KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state
by Huang Xiaojia 14 Apr '25

14 Apr '25

From: Mark Rutland <mark.rutland(a)arm.com> stable inclusion from stable-v6.12.21 commit 79e140bba70bcacc5fe15bf8c0b958793fd7d56f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBZH7N CVE: CVE-2025-22013 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fbc7e61195e23f744814e78524b73b59faa54ab4 ] There are several problems with the way hyp code lazily saves the host's FPSIMD/SVE state, including: * Host SVE being discarded unexpectedly due to inconsistent configuration of TIF_SVE and CPACR_ELx.ZEN. This has been seen to result in QEMU crashes where SVE is used by memmove(), as reported by Eric Auger: https://issues.redhat.com/browse/RHEL-68997 * Host SVE state is discarded *after* modification by ptrace, which was an unintentional ptrace ABI change introduced with lazy discarding of SVE state. * The host FPMR value can be discarded when running a non-protected VM, where FPMR support is not exposed to a VM, and that VM uses FPSIMD/SVE. In these cases the hyp code does not save the host's FPMR before unbinding the host's FPSIMD/SVE/SME state, leaving a stale value in memory. Avoid these by eagerly saving and "flushing" the host's FPSIMD/SVE/SME state when loading a vCPU such that KVM does not need to save any of the host's FPSIMD/SVE/SME state. For clarity, fpsimd_kvm_prepare() is removed and the necessary call to fpsimd_save_and_flush_cpu_state() is placed in kvm_arch_vcpu_load_fp(). As 'fpsimd_state' and 'fpmr_ptr' should not be used, they are set to NULL; all uses of these will be removed in subsequent patches. Historical problems go back at least as far as v5.17, e.g. erroneous assumptions about TIF_SVE being clear in commit: 8383741ab2e773a9 ("KVM: arm64: Get rid of host SVE tracking/saving") ... and so this eager save+flush probably needs to be backported to ALL stable trees. Fixes: 93ae6b01bafee8fa ("KVM: arm64: Discard any SVE state when entering KVM guests") Fixes: 8c845e2731041f0f ("arm64/sve: Leave SVE enabled on syscall if we don't context switch") Fixes: ef3be86021c3bdf3 ("KVM: arm64: Add save/restore support for FPMR") Reported-by: Eric Auger <eauger(a)redhat.com> Reported-by: Wilco Dijkstra <wilco.dijkstra(a)arm.com> Reviewed-by: Mark Brown <broonie(a)kernel.org> Tested-by: Mark Brown <broonie(a)kernel.org> Tested-by: Eric Auger <eric.auger(a)redhat.com> Acked-by: Will Deacon <will(a)kernel.org> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Florian Weimer <fweimer(a)redhat.com> Cc: Fuad Tabba <tabba(a)google.com> Cc: Jeremy Linton <jeremy.linton(a)arm.com> Cc: Marc Zyngier <maz(a)kernel.org> Cc: Oliver Upton <oliver.upton(a)linux.dev> Cc: Paolo Bonzini <pbonzini(a)redhat.com> Signed-off-by: Mark Rutland <mark.rutland(a)arm.com> Reviewed-by: Oliver Upton <oliver.upton(a)linux.dev> Link: https://lore.kernel.org/r/20250210195226.1215254-2-mark.rutland@arm.com Signed-off-by: Marc Zyngier <maz(a)kernel.org> [ Mark: Handle vcpu/host flag conflict ] Signed-off-by: Mark Rutland <mark.rutland(a)arm.com> Signed-off-by: Mark Brown <broonie(a)kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Huang Xiaojia <huangxiaojia2(a)huawei.com> --- arch/arm64/kernel/fpsimd.c | 25 ------------------------- arch/arm64/kvm/fpsimd.c | 33 +++++++++------------------------ 2 files changed, 9 insertions(+), 49 deletions(-) diff --git a/arch/arm64/kernel/fpsimd.c b/arch/arm64/kernel/fpsimd.c index 0137d987631e..bd4f6c6ee0f3 100644 --- a/arch/arm64/kernel/fpsimd.c +++ b/arch/arm64/kernel/fpsimd.c @@ -1707,31 +1707,6 @@ void fpsimd_signal_preserve_current_state(void) sve_to_fpsimd(current); } -/* - * Called by KVM when entering the guest. - */ -void fpsimd_kvm_prepare(void) -{ - if (!system_supports_sve()) - return; - - /* - * KVM does not save host SVE state since we can only enter - * the guest from a syscall so the ABI means that only the - * non-saved SVE state needs to be saved.

From: Wang Weiyang <wangweiyang2(a)huawei.com> stable inclusion from stable-v4.19.247 commit 326192b99c903a2193d820c30ed936cc2402382c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6XS CVE: CVE-2022-49399 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 507b05063d1b7a1fcb9f7d7c47586fc4f3508f98 ] In goldfish_tty_probe(), the port initialized through tty_port_init() should be destroyed in error paths.In goldfish_tty_remove(), qtty->port also should be destroyed or else might leak resources. Fix the above by calling tty_port_destroy().

[PATCH OLK-5.10] HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()
by Pu Lehui 14 Apr '25

From: Zhang Lixu <lixu.zhang(a)intel.com> stable inclusion from stable-v5.10.235 commit d3faae7f42181865c799d88c5054176f38ae4625 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY43Y CVE: CVE-2025-21928 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 07583a0010696a17fb0942e0b499a62785c5fc9f ] The system can experience a random crash a few minutes after the driver is removed. This issue occurs due to improper handling of memory freeing in the ishtp_hid_remove() function. The function currently frees the `driver_data` directly within the loop that destroys the HID devices, which can lead to accessing freed memory. Specifically, `hid_destroy_device()` uses `driver_data` when it calls `hid_ishtp_set_feature()` to power off the sensor, so freeing `driver_data` beforehand can result in accessing invalid memory. This patch resolves the issue by storing the `driver_data` in a temporary variable before calling `hid_destroy_device()`, and then freeing the `driver_data` after the device is destroyed.
