I recently installed LKRG on my debian host ( not whonix ), and I checked the journalctl ouput ( sudo journalctl -b | grep lkrg ) and I got the following output:
parrot lkrg-loader[8266]: INFO: Running 'modprobe p_lkrg msr_validate=0 pcfi_validate=1 ’ …
parrot kernel: [p_lkrg] Loading LKRG…
parrot kernel: [p_lkrg] System does NOT support SMEP. LKRG can’t enforce SMEP validation
parrot kernel: [p_lkrg] System does NOT support SMAP. LKRG can’t enforce SMAP validation
parrot kernel: [p_lkrg] [kretprobe] register_kretprobe() for <ovl_create_or_link> failed! [err=-2]
parrot kernel: [p_lkrg] Can’t hook ‘ovl_create_or_link’ function. This is expected if you are not using OverlayFS.
parrot kernel: [p_lkrg] LKRG initialized successfully!
parrot lkrg-loader[8266]: INFO: Done running modprobe, ok.
Should I be worried about the SMEP and SMAP statements?
And how can I check if LKRG is running and working properly?
