This fixes a bug where saving/restoring, i.e. migrating, a vCPU will fail if WAITPKG (the associated CPUID feature) is enabled for the vCPU, and obviously allows L1 to enable the feature for L2. KVM already effectively exposes ENABLE_USR_WAIT_PAUSE to L1 by stuffing the allowed-1 control ina vCPU's virtual MSR_IA32_VMX_PROCBASED_CTLS2 when updating secondary controls in response to KVM_SET_CPUID(2), but (a) that depends on flawed code (KVM shouldn't touch VMX MSRs in response to CPUID updates) and (b) runs afoul of vmx_restore_control_msr()'s restriction that the guest value must be a strict subset of the supported host value. Although no past commit explicitly enabled nested support for WAITPKG, doing so is safe and functionally correct from an architectural perspective as no additional KVM support is needed to virtualize TPAUSE, UMONITOR, and UMWAIT for L2 relative to L1, and KVM already forwards VM-Exits to L1 as necessary (commit bf653b78f960, "KVM: vmx: Introduce handle_unexpected_vmexit and handle WAITPKG vmexit"). Note, KVM always keeps the hosts MSR_IA32_UMWAIT_CONTROL resident in hardware, i.e. always runs both L1 and L2 with the host's power management settings for TPAUSE and UMWAIT. See commit bf09fb6cba4f ("KVM: VMX: Stop context switching MSR_IA32_UMWAIT_CONTROL") for more details.

FAILED: patch "[PATCH] perf probe: Fix to get the DW_AT_decl_file and" failed to apply to 4.9-stable tree

So it should be an unsigned integer data. Also, even though the standard doesn't clearly say the DW_AT_call_file is signed or unsigned, the elfutils (eu-readelf) interprets it as unsigned integer data and it is natural to handle it as unsigned integer data as same as DW_AT_decl_file.

FAILED: patch "[PATCH] perf probe: Fix to get the DW_AT_decl_file and" failed to apply to 5.10-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. Possible dependencies: a9dfc46c67b5 ("perf probe: Fix to get the DW_AT_decl_file and DW_AT_call_file as unsinged data") f828929ab7f0 ("perf probe: Use dwarf_attr_integrate as generic DWARF attr accessor") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From a9dfc46c67b52ad43b8e335e28f4cf8002c67793 Mon Sep 17 00:00:00 2001 From: "Masami Hiramatsu (Google)" <mhiramat(a)kernel.org> Date: Sat, 5 Nov 2022 12:01:14 +0900 Subject: [PATCH] perf probe: Fix to get the DW_AT_decl_file and DW_AT_call_file as unsinged data DWARF version 5 standard Sec 2.14 says that Any debugging information entry representing the declaration of an object, module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and DW_AT_decl_column attributes, each of whose value is an unsigned integer constant. So it should be an unsigned integer data. Also, even though the standard doesn't clearly say the DW_AT_call_file is signed or unsigned, the elfutils (eu-readelf) interprets it as unsigned integer data and it is natural to handle it as unsigned integer data as same as DW_AT_decl_file. This changes the DW_AT_call_file as unsigned integer data too.
