Test failure output: CVE-2017-5715: VULN (IBRS+IBPB or retpoline+IBPB+RSB filling, is needed to mitigate the vulnerability) Test description: CVE-2017-5715 branch target injection (Spectre Variant 2) Impact: Kernel Mitigation 1: new opcode via microcode update that should be used by up to date compilers to protect the BTB (by flushing indirect branch predictors) Mitigation 2: introducing "retpoline" into compilers, and recompile software/OS with it Performance impact of the mitigation: high for mitigation 1, medium for mitigation 2, depending on your CPU ref: https://github.com/speed47/spectre-meltdown-checker https://qa-reports.linaro.org/lkft/linux-stable-rc-5.4-oe/build/v5.4.23-153-g1254e88b4fc1/testrun/1264789/log https://qa-reports.linaro.org/lkft/linux-stable-rc-5.4-oe/tests/spectre-meltdown-checker-test/CVE-2017-5715 Summary ------------------------------------------------------------------------ kernel: 5.4.24-rc1 git repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git git branch: linux-5.4.y git commit: 1254e88b4fc1470d152f494c3590bb6a33ab33eb git describe: v5.4.23-153-g1254e88b4fc1 Test details: https://qa-reports.linaro.org/lkft/linux-stable-rc-5.4-oe/build/v5.4.23-153-g1254e88b4fc1 Regressions (compared to build v5.4.23) ------------------------------------------------------------------------ i386: spectre-meltdown-checker-test: * CVE-2017-5715 x86: spectre-meltdown-checker-test: * CVE-2017-5715 No fixes (compared to build v5.4.23) Ran 27633 total tests in the following environments and test suites.
