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=yCONFIG_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?

Ignore my previous email, I got the issue that CONFIG_SECURITY should have
been enabled also(That is a dependency)

Hi Team,
Does anybody have any experience in writing the apparmor profile and
confine some of the openbmc application? I pulled the apparmor in the
openbmc image but it is not confining the openbmc application.Confining the
application on ubuntu works fine but that is not true with openbmc.
I am chasing this issue with apparmor team through
https://gitlab.com/apparmor/apparmor/-/issues/183
