Pythons find_library is broken with binutils 2.34, and numpy could not import libraries because of not properly aligned ELF's.
This is the second time binutils 2.34 got reverted. Next time, we should have a dedicated Hydra job for it.
This reverts commit 629fa8a2d4, reversing
changes made to 4ddd080d19.
Some packages don’t work correctly with pie. Here I disable it for:
- busybox
- linux kernel
- kexectools
I also get rid of the Musl conditional for disabling pie in GCC and
Binutils. Some day we might want to enable PIE without Musl and it
will be useful to have the *just* work with our compiler and linkers.
These don’t like having -fPIE set for them. We should disable
hardening all the time, but in the interest of not changing hashes,
this only disables it for Musl (where it is now the default).
(cherry picked from commit a3a6884649354a660326acd68c1bd08ffd2dcfa2)
In 3027bca, binutils was upgraded from 2.28.1 to 2.30. However, in 2.30,
the ldmain.c file within binutils, which the nixpkgs new-dtags.patch
file is meant to modify, was changed in such a way that the patch no
longer works. As a result, the new dtags are not actually enabled, and
binaries are built with RPATH set instead of RUNPATH, thereby preventing
LD_LIBRARY_PATH from overriding this built-in path. This change corrects
this. The patch file is no longer necessary because binutils's ldmain.c
now sets link_info.new_dtags based on the configuration flags.
This was probably not noticed immediately because, when the derivation
is built with nix-build, the fixupPhase runs patchelf --shrink-rpath.
patchelf converts any RPATH in the binary into RUNPATH (unless
--force-rpath is specified). Of course, if the binary is built without
nix-build (such as in a nix-shell), this never occurs, and any RPATH in
the binary is left in place.
This fails for me:
> compressed_output.cc:320:20: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
> gold_warning(_("not compressing section data: zlib error"));
> ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

> compressed_output.cc:320:20: note: treat the string as an argument to avoid this
> gold_warning(_("not compressing section data: zlib error"));
> ^
> "%s",
> ./system.h:40:20: note: expanded from macro '_'
> # define _(String) gettext (String)
^
Disabling format hardening should hopefully be harmless here. If it's a problem we can also make it conditional.
