 |
|
hello gentoo community,
i'm using stage3-amd64-musl-llvm-20241027T164832Z.tar.xz for installation and update it today, add manual the following to make.conf (enable hardening flags):
| Code: | WARNING_FLAGS="-Werror=odr -Werror=strict-aliasing"
HARDENING_CFLAGS="-fPIC -fPIE -fstack-clash-protection -fstack-protector-strong -fcf-protection=full -D_FORTIFY_SOURCE=2"
HARDENING_LDFLAGS="-Wl,-z,relro,-z,now -pie"
COMMON_FLAGS="-march=native -O2 -pipe -flto=thin ${WARNING_FLAGS}"
CFLAGS="${COMMON_FLAGS} ${HARDENING_CFLAGS}"
CXXFLAGS="${COMMON_FLAGS} ${HARDENING_CFLAGS}"
LDFLAGS="${LDFLAGS} -Wl,-O2 -Wl,--as-needed ${HARDENING_LDFLAGS}" |
Then i recompile the whole system with: | Code: | | emerge -e --ask --update --newuse --with-bdeps=y --quiet --deep @world |
One program failed: dev-libs/elfutils with the following error:
| Code: | | configure: error: __thread support required |
I then try nopie and nossp to /etc/portage/package.env from here: https://wiki.gentoo.org/wiki/Hardened_Gentoo for just elfutils.
But it's still failed but when i remove all the ${WARNING_FLAGS} ${HARDENING_CFLAGS} ${HARDENING_LDFLAGS} from make.conf like just use:
| Code: | CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
LDFLAGS="${LDFLAGS} -Wl,-O2 -Wl,--as-needed" |
it works.
So what i have to add to another /etc/portage/env/unknown to make it just work for dev-libs/elfutils ?

-no-pie don't work via /etc/portage/env but removing -fPIE from HARDENING_CFLAGS works. weird.
The wiki entry is wrong ! it should be -fno-PIE and not -no-pie https://wiki.gentoo.org/wiki/Hardened_Gentoo |

| Your answer doesn't seem to explain what happened here, because the default is PIE anyway - as are the other hardening flags (so no need for you to be setting it), and the only error you pointed out was something you tried to work around it? |

hello sam_,
thank you for taking time and answering i hope i can explain it a bit more:
Make.conf | Code: | CC="clang"
CPP="clang-cpp" # necessary for xorg-server and possibly other packages
CXX="clang++"
AR="llvm-ar"
NM="llvm-nm"
RANLIB="llvm-ranlib"
WARNING_FLAGS="-Werror=odr -Werror=strict-aliasing"
HARDENING_CFLAGS="-fPIC -fPIE -fstack-clash-protection -fstack-protector-strong -fcf-protection=full -D_FORTIFY_SOURCE=2"
HARDENING_LDFLAGS="-Wl,-z,relro,-z,now -pie"
COMMON_FLAGS="-march=native -O2 -pipe -flto=thin ${WARNING_FLAGS}"
CFLAGS="${COMMON_FLAGS} ${HARDENING_CFLAGS}"
CXXFLAGS="${COMMON_FLAGS} ${HARDENING_CFLAGS}"
LDFLAGS="${LDFLAGS} -Wl,-O2 -Wl,--as-needed ${HARDENING_LDFLAGS}"
FEATURE="cgroup ipc-sandbox network-sandbox noman nodoc noinfo" |
I can only compile dev-libs/elfutils when i add nopie (/etc/portage/env/nopie) to /etc/portage/package.env elfutils.
/etc/portage/env/nopie
| Code: | CFLAGS="${CFLAGS} -fno-PIE"
CXXFLAGS="${CXXFLAGS} -fno-PIE"
LDFLAGS="${LDFLAGS} -fno-PIE" |
If compile without nopie i get the following error:

That i don't have to add hardening flag manual is new to me because if i don't add these flags in compiler log there a missing.
Example tmux here is a compiler output line without the hardend flags vars in make.conf.

| The reason you don't have to add the hardening flags manually - and why they don't appear in the log - is that we patch the toolchain (for GCC) and/or use configuration files (for Clang). They're there but not appearing in the log because the compiler gets them from elsewhere. For Clang, you can see them in /etc/clang. |
