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-5.5-oe/tests/spectre-meltdown-checker-test/CVE-2017-5715 https://lkft.validation.linaro.org/scheduler/job/1264643#L21206 Summary ------------------------------------------------------------------------ kernel: 5.5.8-rc1 git repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git git branch: linux-5.5.y git commit: 3517b32c0774341d492140b2be08c4bf6d1a833e git describe: v5.5.7-177-g3517b32c0774 Test details: https://qa-reports.linaro.org/lkft/linux-stable-rc-5.5-oe/build/v5.5.7-177-g3517b32c0774 Regressions (compared to build v5.5.7) ------------------------------------------------------------------------ i386: spectre-meltdown-checker-test: * CVE-2017-5715 x86: spectre-meltdown-checker-test: * CVE-2017-5715 No fixes (compared to build v5.5.7) Ran 25662 total tests in the following environments and test suites.
