Subject: LKRG compilation hardening flags

Could you please kindly have a look and let me know if something needs

(This is what happened building LKRG using DKMS. Shouldn't make a
difference though, since it is using the usual upstream makefile.)

checksec -f /lib/modules/4.19.0-6-amd64/updates/dkms/p_lkrg.ko
RELRO           STACK CANARY      NX            PIE             RPATH
     RUNPATH	Symbols		FORTIFY	Fortified	Fortifiable  FILE
No RELRO        Canary found      NX disabled   Not an ELF file   No
RPATH   No RUNPATH   866 Symbols	Yes	0		2

hardening-check /lib/modules/4.19.0-6-amd64/updates/dkms/p_lkrg.ko
 Position Independent Executable: not a known ELF type!? ()
 Stack protected: yes
 Fortify Source functions: no, only unprotected functions found!
 Read-only relocations: no, non-ELF (ignored)
 Immediate binding: no, non-ELF (ignored)

I guess, should something need fixing, it's a task for the upstream

Kind regards,
