CPUs which have no # microcode update can be mitigated by disabling TSX in the BIOS if # the BIOS provides a tunable. # # Newer CPUs will have a bit set which indicates that the CPU is not # vulnerable, but the MSR to disable TSX will be available # nevertheless as it is an architected MSR. That means the kernel # provides the ability to disable TSX on the kernel command line, # which is useful as TSX is a truly useful mechanism to accelerate # side channel attacks of all sorts. # # 2) iITLB Multihit (NX) - 'No eXcuses' # # iTLB Multihit is an erratum where some Intel processors may incur # a machine check error, possibly resulting in an unrecoverable CPU # lockup, when an instruction fetch hits multiple entries in the # instruction TLB. This can occur when the page size is changed # along with either the physical address or cache type. A malicious # guest running on a virtualized system can exploit this erratum to # perform a denial of service attack. # # The workaround is that KVM marks huge pages in the extended page # tables as not executable (NX). If the guest attempts to execute in # such a page, the page is broken down into 4k pages which are # marked executable. The workaround comes with a mechanism to # recover these shattered huge pages over time. # # Both issues come with full documentation in the hardware # vulnerabilities section of the Linux kernel user's and administrator's # guide. # # Thanks to all patch authors and reviewers who had the extraordinary # priviledge to be exposed to this nuisance. # # Special thanks to Borislav Petkov for polishing the final TAA patch # set and to Paolo Bonzini for shepherding the KVM iTLB workarounds and # providing also the backports to stable kernels for those!" # # * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/speculation/taa: Fix printing of TAA_MSG_SMT on IBRS_ALL CPUs # Documentation: Add ITLB_MULTIHIT documentation # kvm: x86: mmu: Recovery of shattered NX large pages # kvm: Add helper function for creating VM worker threads # kvm: mmu: ITLB_MULTIHIT mitigation # cpu/speculation: Uninline and export CPU mitigations helpers # x86/cpu: Add Tremont to the cpu vulnerability whitelist # x86/bugs: Add ITLB_MULTIHIT bug infrastructure # x86/tsx: Add config options to set tsx=on\|off\|auto # x86/speculation/taa: Add documentation for TSX Async Abort # x86/tsx: Add "auto" option to the tsx= cmdline parameter # kvm/x86: Export MDS_NO=0 to guests when TSX is enabled # x86/speculation/taa: Add sysfs reporting for TSX Async Abort # x86/speculation/taa: Add mitigation for TSX Async Abort # x86/cpu: Add a "tsx=" cmdline option with TSX disabled by default # x86/cpu: Add a helper function x86_read_arch_cap_msr() # x86/msr: Add the IA32_TSX_CTRL MSR # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 eb094f06963bb0fd8134c6a9b805d4ad0002a7d4 # < make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- defconfig # make -s -j 24 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:175:2: warning: #warning check me!
