I'm retesting position independent executables. The only thing missing from
the lfs cvs tools would be binutils that understands -pie. I tried FSF cvs
binutils and they seem to work fine compared to HJL. Gentoo has made a new
patch which modifies the gcc specs to build propolice/et_dyn by default. This
should be helpfull to the non-x86 people, and gcc will be able to bootstrap
with propolice/et_dyn. I tried changing the patch to convert it from -fPIC to
-fPIE but it looks like the patch breaks 'gcc -pie -fpie', which is looked
for by gcc-2.3.3 configure. So for now a new hgcc.sh will still work for
-fpie. Like with propolice, glibc needs to be built twice. The first time
will give the libs for gcc to be built with -fpie, after glibc and gcc are
built, then when glibc is built again "checking for -fpie" should say "yes"
in chap6, in chap5 it wont.
Part of glibc uses an executable stack. Gentoo has a dl patch for glibc to fix
this for Pax. It seems to be a better fix than the patch from redhat. Aswell
Which is a fix from the Owl kernel project. Proof is here (I think):
Both of these patches would be a good idea to add to glibc-2.3.3.
The gcc-pie patch was fixed upstream by mandrake. It now patches cleanly on
both gcc-3.3.1 and 3.3.2. Right now I'm trying to perfect the specs for -fpie
and I can update winter.txt so it has some real enforcement on first boot.
The future it nearing. I think this should start being tested asap.
