[arch-projects] [devtools] [PATCH] enforce hardening flags and use PIE on x86_64
by Daniel Micay 24 Jul '14

24 Jul '14

PIE is required for full address space layout optimization (ASLR) and there is little to no benefit from ASLR without it since global ELF tables (GOT/PLT) and application code are at known locations. A wrapper script is required in order to pass the correct flags for executables without changing the flags for libraries. It adds `-pie` when linking (no `-c` switch) if `-static` or `-shared` are not passed, and `-fPIE` whenever `-fPIC` is not already there. This technique comes from the Debian hardening wrappers. Position independent code is expensive on i686, so it's only enabled by default on x86_64 where the cost is negligible. It can be enabled on a package-by-package basis on i686. The same cost already exists for any code in a dynamic library. The hardening-wrapper package also enforces the chosen hardening flags even when build systems aren't using CFLAGS / CXXFLAGS / LDFLAGS from the environment. It would need to be moved from [community] to [core]. --- archbuild.in | 5 +++-- makechrootpkg.in | 12 +++++++++++- 2 files changed, 14 insertions(+), 3 deletions(-) diff --git a/archbuild.in b/archbuild.in index ae2f511..419ae5b 100644 --- a/archbuild.in +++ b/archbuild.in @@ -2,7 +2,7 @@ m4_include(lib/common.sh) -base_packages=(base-devel) +base_packages=(base-devel hardening-wrapper) makechrootpkg_args=(-c -n) cmd="${0##*/}" @@ -67,11 +67,12 @@ if ${clean_first} || [[ ! -d "${chroots}/${repo}-${arch}" ]]; then "${base_packages[@]}" || abort else lock 9 "${chroots}/${repo}-${arch}/root.lock" "Locking clean chroot" + # upgrade and install any new packages from base_packages arch-nspawn \ -C "@pkgdatadir@/pacman-${repo}.conf" \ -M "@pkgdatadir@/makepkg-${arch}.conf" \ "${chroots}/${repo}-${arch}/root" \ - pacman -Syu --noconfirm || abort + pacman -Syu --noconfirm --needed "${base_packages[@]}" || abort fi msg "Building in chroot for [${repo}] (${arch})..." diff --git a/makechrootpkg.in b/makechrootpkg.in index 97c7780..ad804fc 100644 --- a/makechrootpkg.in +++ b/makechrootpkg.in @@ -320,7 +320,17 @@ _chrootbuild() { exit 1 fi - sudo -u nobody makepkg $makepkg_args || exit 1 + # enforced compiler hardening flags (can be overriden in a PKGBUILD) + export HARDENING_BINDNOW=0 HARDENING_FORTIFY=2 HARDENING_RELRO=1 + export HARDENING_STACK_CHECK=0 HARDENING_STACK_PROTECTOR=2 + . /etc/makepkg.conf + if [[ $CARCH = i686 ]]; then + export HARDENING_PIE=0 + else + export HARDENING_PIE=1 + fi + + sudo -E -u nobody makepkg $makepkg_args || exit 1 if $run_namcap; then pacman -S --needed --noconfirm namcap -- 2.0.2

[arch-projects] [netctl][PATCH] Disable IPv6 on IP6=no
by Jouke Witteveen 05 Jul '14

05 Jul '14

--- It was proposed to disable IPv6 entirely in case of "IP6=no". Currently we only disable processing of router advertisements. This looks OK to me, but I would really like to get some feedback on this one, as I cannot extensively test the consequences. src/lib/ip | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/lib/ip b/src/lib/ip index 66aab56..9600504 100644 --- a/src/lib/ip +++ b/src/lib/ip @@ -47,11 +47,12 @@ ip_set() { case "$IP6" in dhcp*|stateless|static) [[ -d "/proc/sys/net/ipv6" ]] || modprobe ipv6 + sysctl -q -w "net.ipv6.conf.$interface_sysctl.disable_ipv6=0" [[ $IP6 == "static" ]] sysctl -q -w "net.ipv6.conf.$interface_sysctl.accept_ra=$?" ;; no) - [[ -d "/proc/sys/net/ipv6" ]] && sysctl -q -w "net.ipv6.conf.$interface_sysctl.accept_ra=0" + [[ -d "/proc/sys/net/ipv6" ]] && sysctl -q -w "net.ipv6.conf.$interface_sysctl.disable_ipv6=0" ;; "") # undefined IP6 does not prevent RA's from being received -> nop ;; -- 2.0.1
