coreutils is part of stdenv, which doesn't allow openssl currently.
It's unclear that adding openssl to stdenv was intended,
but if it was it was not discussed or mentioned.
To unbreak "all the things", reverting until this
has been discussed and a proper fix has been put together.
This reverts commit df9f76c62d47e856afedb7e4d1b921e1000a8dc1, reversing
changes made to 585ded73298c0f74e4bed64a22367b9914f00f06.
Originally this was introduced in 055e646b ('coreutils: Guard against compiler not supporting __builtin_stpncpy_chk') four years ago. Right now this doesn't seem to serve any purpose and it conflicts with the hardening flags:
<command line>:2:9: warning: '_FORTIFY_SOURCE' macro redefined [-Wmacro-redefined]
#define _FORTIFY_SOURCE 2
^
<command line>:1:9: note: previous definition is here
#define _FORTIFY_SOURCE 0
^
1 warning generated.
The main changes are in libSystem, which lost the coretls component in 10.13
and some hardening changes that quietly crash any program that uses %n in
a non-constant format string, so we've needed to patch a lot of programs that
use gnulib.
`make install` was failing presumably due to an upstream cross-compilation bug:
Makefile:3440: *** Recursive variable 'INSTALL' references itself (eventually). Stop.
While at it, remove the old ugly cross buildPhase. It was seemingly
trying to work around the fact that the man pages are generated by
piping each command's --help output to help2man. That obviously doesn't
work while cross-compiling.
Instead, set PERL=missing in the environment to make the build system
think there's no perl available to run help2man. (This approach was
stolen from buildroot.)
With the symlinked build it's only renaming 'coreutils' to
'gcoreutils' and leaving all the actual command symlinks alone.
Instead of custom renaming scripts, let's use --program-prefix
from the autotools kitchen sink. This has the nice(?) bonus that
the manpages also get prefixed with 'g' now.
The build system refuses to enable both single-binary build and
--program-prefix - but the symlink-based single-binary build couldn't
possibly work either (as it will be looking at "$0" for which command
to execute).
Our coreutils now uses single-binary-build mode where, by default,
simple shebang scripts are used for all the binaries. That doesn't work
e.g. with the Linux unpacker which only handles standard binaries and
symlinks. Let's use the symlinked mode instead for boostrapping.
This does NOT change any stdenv hashes.
I only tested the case most important to me:
$ nix-build pkgs/top-level/release.nix -A stdenvBootstrapTools.x86_64-linux.test
The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable
To enable specific hardening flags
Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow
The patch no longer applies as it's applied in the 8.25 release.
While at it don't use FORCE_UNSAFE_CONFIGURE on ARM as I don't see why
it's needed and it works for me without it.
Build-tested GNU hello on ARMv7 and verified that this affect its hash
on i686.
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
It was using 'null' instead of '[]' in case of no patches. So I change
it to provide 'null'.
(cherry picked from commit 56ff659e5d1fffd371786a3b8237129ee365ca5c)
I pick the patch from upstream, and I apply only for ARM to avoid rebuilding
stdenv.
