This HIGHLY EXPERIMENTAL patch adds PAX header support to the gold linker binutils-2.21.1 (The patch applies with some fuzz to 2.22 and appears to work)
I have just finished a HLFS (2.6.32.56 + 201202051926 grsec, 32-bit x86) variant build using binutils-2.22 using the following patches - http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/binutils/2.22/62_all_binutils-2.22-hardened-crtbegin.patch?view=markup&revision=1.1 - http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/binutils/2.22/63_all_binutils-2.22-pt-pax-flags-20111121.patch?view=markup&revision=1.1 - http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo/src/patchsets/binutils/2.22/66_all_binutils-2.22-warn-textrel.patch?view=markup Plus the included patch. I configured binutils with --enable-shared --enable-gold=yes --enable-ld=yes The system build used the bfd (standard) linker, but post-build, I compiled and linked pax-test-0.9.9 once with bfd and once with gold. The resultant paxtest.log are identical with "kiddie" and "blackhat" runs, although the resultant binaries are different. I have done very little testing otherwise, and am not a C++ guy, but I am aware of only one issue - binaries linked with this patched gold have RANDEXEC enabled by default, unlike bfd linked binaries. -dean takemori
