The workaround with -Wp,-U_FORTIFY_SOURCE doesn't seem to work for me any more, so if there are better ideas on how to enable RELRO and make checksec happy — let me know.

Added -Wp,-U_FORTIFY_SOURCE to make RELRO work.

Can confirm it still compiles and successfully extracts files.

As an experiment, I've made an attempt to build 7-zip using meson in -5.

Let me know if it works for you all.

Applied more hardening, but noticed that there's no RELRO:

RELRO           STACK CANARY      NX            PIE             RPATH      RUNPATH      Symbols         FORTIFY Fortified       Fortifiable     FILE
No RELRO        Canary found      NX enabled    PIE enabled     No RPATH   No RUNPATH   No Symbols        Yes   6               16              /usr/bin/7zz

No idea what else it needs other than -z relro -z now.

@post-factum Seems to work great, thanks for the fast fix!

post-factum commented on 2022-05-12 19:18 (UTC)

I've also added extra hardening, please let me know if it breaks anything.

post-factum commented on 2022-05-12 19:02 (UTC)

@katt should be fixed in -2.

Unable to build, probably due to GCC 12:

I created 7-zip-full package, attempting to actually replace p7zip.
