Subject: LKRG compilation hardening flags
Could you please kindly have a look and let me know if something needs
fixing?
(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
/lib/modules/4.19.0-6-amd64/updates/dkms/p_lkrg.ko
hardening-check /lib/modules/4.19.0-6-amd64/updates/dkms/p_lkrg.ko
/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
makefile?
Kind regards,
Patrick
