Hi All, I was trying to pull apparmor in openbmc, all the user space application got pulled however I was unable to build the kernel with apparmor support. I made the following kernel configuration to include the apparmor( https://github.com/openbmc/linux/blob/dev-5.10/Documentation/admin-guide/LSM/apparmor.rst ) CONFIG_SECURITYFS=y CONFIG_SECURITY_NETWORK=y CONFIG_SECURITY_PATH=y CONFIG_SECURITY_APPARMOR=y CONFIG_DEFAULT_SECURITY="apparmor" CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1 CONFIG_AUDIT=y In the build tree, kernel is not picking the above config parameters and I was getting the following logs in the config_build_log which suggest that kernel doesn't like these config. tmp/work-shared/hgx/kernel-source/.kernel-meta/cfg/merge_config_build.log Value requested for CONFIG_SECURITY_PATH not in final .config Requested value: CONFIG_SECURITY_PATH=y CONFIG_SECURITY_PATH=y Actual value: Value requested for CONFIG_SECURITY_APPARMOR not in final .config Requested value: CONFIG_SECURITY_APPARMOR=y CONFIG_SECURITY_APPARMOR=y Actual value: Value requested for CONFIG_DEFAULT_SECURITY not in final .config Requested value: CONFIG_DEFAULT_SECURITY="apparmor" CONFIG_DEFAULT_SECURITY="apparmor" Actual value: Value requested for CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE not in final .config Requested value: CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1 CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1 Actual value: Can somebody suggest me what I am missing here?
