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/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 eb094f06963bb0fd8134c6a9b805d4ad0002a7d4 # < make -s -j 10 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 10 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/lib/test_kasan.c: In function 'kasan_alloca_oob_left': /kisskb/src/lib/test_kasan.c:527:1: warning: 'kasan_alloca_oob_left' uses dynamic stack allocation } ^ /kisskb/src/lib/test_kasan.c: In function 'kasan_alloca_oob_right': /kisskb/src/lib/test_kasan.c:537:1: warning: 'kasan_alloca_oob_right' uses dynamic stack allocation } ^ In file included from /kisskb/src/include/linux/kernel.h:15, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/ubifs/ubifs.h:16, from /kisskb/src/fs/ubifs/orphan.c:10: /kisskb/src/fs/ubifs/orphan.c: In function 'orphan_delete': /kisskb/src/fs/ubifs/debug.h:158:11: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'ino_t' {aka 'unsigned int'} [-Wformat=] pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:288:21: note: in definition of macro 'pr_fmt' #define pr_fmt(fmt) fmt ^~~ /kisskb/src/include/linux/dynamic_debug.h:143:2: note: in expansion of macro '__dynamic_func_call' __dynamic_func_call(__UNIQUE_ID(ddebug), fmt, func, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/dynamic_debug.h:153:2: note: in expansion of macro '_dynamic_func_call' _dynamic_func_call(fmt, __dynamic_pr_debug, \ ^~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:336:2: note: in expansion of macro 'dynamic_pr_debug' dynamic_pr_debug(fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~ /kisskb/src/fs/ubifs/debug.h:158:2: note: in expansion of macro 'pr_debug' pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~ /kisskb/src/fs/ubifs/debug.h:170:29: note: in expansion of macro 'ubifs_dbg_msg' #define dbg_gen(fmt, ...) ubifs_dbg_msg("gen", fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~ /kisskb/src/fs/ubifs/orphan.c:132:3: note: in expansion of macro 'dbg_gen' dbg_gen("deleted twice ino %lu", orph->inum);
