Possibly I'm missing something but with these patches applied on top of next-integrity, and the following lines added to /etc/ima/ima-policy:

measure func=LSM_STATE template=ima-buf
measure func=LSM_POLICY

I still don't get the selinux-state or selinux-policy-hash entries in the ascii_runtime_measurements file.  No errors during loading of the ima policy as far as I can see.

Could you please check if the following config is set?

Try changing /sys/fs/selinux/checkreqprot and check ascii_runtime_measurements file again?

Also, could you please check if
/sys/kernel/security/integrity/ima/policy contains LSM_STATE and LSM_POLICY entries?
