Title:
test_250_config_security_perf_events_restrict in kernel security test
failed with 4.15 KVM kernel
Status in ubuntu-kernel-tests:
Fix Released
Status in linux-kvm package in Ubuntu:
Fix Committed
Status in linux-kvm source package in Bionic:
Fix Released
Bug description:
== Justification ==
In the Bionic KVM kernel, the CONFIG_FORTIFY_SOURCE and
CONFIG_SECURITY_PERF_EVENTS_RESTRICT were not set, they need to be enabled to
meet the security team's requirement.
== Test ==
Before enabling the config, test case test_190_config_kernel_fortify and
test_250_config_security_perf_events_restrict will fail in the kernel
security testsuite for the kernel SRU regression test.
It will pass with these two patches applied, tested on a KVM node.
== Fix ==
Set CONFIG_SECURITY_PERF_EVENTS_RESTRICT to "y".
Set CONFIG_FORTIFY_SOURCE to "y".
== Regression Potential ==
Minimal.
No code changes, just two config changes without disabling any other configs.
