Since this week new linux-2.6/master kernels don't work with my
initial ram disks. The sleep binary runs repeatingly into
segmentation faults until the Busybox shell starts. My system is a
x86-64 with Kubuntu Feisty Fawn.
By bisecting I found out that the PIE randomization patch (commit 60bfba7e)
appears to cause the segmentation faults.
Digging further into the issue I found out, that the sleep binary
on the initial ramdisk is a klibc binary. /usr/bin/file says it is
statically linked and uses shared libraries. I have no clue about
klibc, but the binaries seem to be statically linked, but load a
shared library; probably at a fixed address. Other klibc binaries are also
running into segmentation faults. Busybox is working, but it is
statically linked and doesn't use a shared library.
It looks like that the PIE randomization patch breaks klibc
binaries on x86-64.

Interesting.
klibc binaries are indeed statically linked, but composed of two
different ELF images: the application itself and the shared libary
(which is referenced from the application header as the "interpreter").
Neither of these is an ET_DYN file; they are both ET_EXEC, so it
*should* be unaffected by the PIE randomization patch. Obviously, that
seems to not be the case.
My guess is that this patch mishandles interpreter images which are
ET_EXEC. Jan, any insight?

oh bugger I just spent a few hours bisecting to find this headache
only to find someone else had 8 hours ago... *sigh*
anyhow also seeing seg faults here on a amd64 ubuntu system
reverting the PIE randomization patch made it go away

I don't think we'll be fixing this in time for -rc1. I'll revert
it. Thanks for the prompt and accurate reporting.

Well, they don't run on Fedora 6 either (which has the same code, it's
part of exec-shield):
$ strace ./cat
execve("./cat", ["./cat"], [/* 55 vars */]) = -1 ENOENT (No such file or directory)
...
$ file cat
cat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked (uses shared libs), stripped
Funny nobody noticed that before...

After installing klibc.so and klibc-<ID>.so into /lib everything works:

Ulrich, did your initrd contain the correct .so? Did you try rebuilding klibc after
building the new kernel?

Chuck, my binaries run always into a segmentation violation. So
ENOENT is not the issue. (Notify it was on an x86-64.)

Yes, these files were present in the initrd.img file. I checked it
by unpacking the initrd.img file. Notify also that I used
git-bisect to identify the PIE patch. This requires successful
builds. Reverting the patch clearly resolved the issue at the end.
> Ulrich, did your initrd contain the correct .so?
Sure! I have only one klibc-*.so on my box in /lib. I diffed the
file in the unpacked initrd.img with the file in /lib and there
has been no difference.
I always recreate the initial ramdisk after the kernel rebuild
with make install and my own installkernel script, which uses
mkinitramfs. The mkinitramfs script ensures that the klibc so
object from /lib and the klibc binaries from /usr/lib/klibc/bin
are copied into the initrd image. Usually that works without any
issue on x86, x86-64. PPC can't use make install, but I use
mkinitramfs there too, which handles klibc the same way.
> Did you try rebuilding klibc after building the new kernel?
Rebuilding klibc doesn't make sense from my point of view. What
should be the point of it?

Okay, I tested with Fedora on x86_64 and it worked there too.
(Not that that proves much.)
Did you capture any of the error messages, like the address
of the segfault?

FWIW, on x86-64, this should show up in dmesg.

Guys, this is at boot time and most of the binaries don't work.
However at the end busybox is called and then there is a shell,
where I can call the binaries and force the segmentation
violation. Pencil and paper work usually. But right now I don't
have the broken kernel anymore and it's 1 am here. Wait for
tomorrow.

Ok, I have tested it again.
The message looks like:
sleep[7888]: segfault at 000000000004001C rip 000000000004001C rsp 00007fff14776468 error 14
Repeated calls get the same message with the stack pointer
changing. Other binaries (mount) have a segmentation fault at
another addressi (0x400184). It appears that the instruction
pointer fails at the start address of the klibc binary. Notify
that this lies in the binary itself and not in the /lib/klibc*.so
object, so it appears that the klibc binary sections are loaded at
randomized addresses.

Hi Ulrich,
I just now quickly tried to with klibc-1.5 on i386 with the
PIE-randomization patched kernel, and it seems to load static libraries
fine.
I just downloaded klibc-1.5, built it, and executed a few of the programs
in usr/utils/static, all of them worked. Does this also work for you and
you are experiencing the problems solely when the binaries are being run
from initramfs during boot?
I will test more shortly (on x86_64, directly from initramfs) in order to
reproduce.
Thanks,

What about shared binaries?

My guess would be the former, rather than the latter. I haven't had a
chance to reproduce it myself yet (I'm on the road), but I will try to
get the time tomorrow.

Works for me too on the pie-randomization patched kernel.
So it seems to me that either it is something x86_64 specific or
initramfs-specific. Will try to reproduce it.

I still wasn't successful reproducing it with 2.6.23-rc1 +
pie-randomization.patch with klibc-1.5 on x86_64 system -- all programs
from 'shared' and 'static' seem to be running well.
Ulrich, could you please send me your .config? Thanks,

Here is the .config file. I used it directly with 60bfba7e8 and
could reproduce the bug. (All other builds after the patch could
also reproduce the bug.) I use klibc-utils 1.4.30-3ubuntu2 which
depends on libklibc with the same version number. The processor is
an Intel Core 2 Duo T5500 @ 1.66 GHz, if that helps.

Thanks, I used your .config against 60bfba7e8 on x86_64, and still can't
seem to be able to reproduce the problem:
linux-w027:~ # echo "test" | ./klibc-1.5/usr/utils/shared/cat
test
linux-w027:~ # echo "test" | ./klibc-1.5/usr/utils/static/cat
test
hpa, were you successful reproducing this?
Bret, I can see that you also reported some related segfaults, what were
your conditions that triggered it please?

not really much to it just did the usual make oldconfig on a current
git and installed
it with ubuntus kernel tools and it was broken
the system is a 64bit feisty setup nothing special to me at least
i can attach the .config later (not near the computer and its not on atm)

Note that the vaddr here can overlap the binary which is linked starting
at 0x400000.
This is the bug which I have found and fixed some time ago:
http://git.kernel.org/?p=libs/klibc/klibc.git;a=commit;h=10df6dfb13ffefe716f12136bbc667f18ff64744
The fix was included in klibc-1.4.35, but does not seem to be applied in
your case (the alignment is still 2**21 - it should be 2**20) - so
either you are using an old klibc, or the "-z max-page-size=0x100000"
option does not take effect for some reason.
In my case the buggy klibc worked fine with a stock 2.6.18 kernel, but
broke when the execshield patch was applied - and the commit 60bfba7e
code comes from execshield, so it looks like the same problem.

Yup... it should probably be pointed out the reason the old kernel
worked was nothing but pure dumb luck. This was a GNU ld change which
needed to be undone for klibc. It's unfortunate that stock x86-64
binaries leave as little of a null pointer range as they do, but that's
life, unfortunately. The other alternative is to map klibc just below
the 2 GB point, which would also work, but the old way broke when the ld
change went in. As previously stated, klibc-1.4.35 or higher fixes this.

I think you found it: 1.4.30-3ubuntu2.

Just for the record: The kernel with the PIE patch boots perfectly
using the klibc 1.5 shared binaries on my machine.

Thanks for pointing this out. So it seems that maybe the mainline revert
of pie-randomization.patch was a little bit premature. Bret -- could you
please clarify whether you have experienced also klibc-related segfaults
with pie-randomization.patch applied, or you have had just random binaries
segfaulting, as you pointed out here: http://lkml.org/lkml/2007/7/21/31
Seems like you are also using ubuntu, same as Ulrich, so you might have
been hitting the very same behavior of klibc-1.4.
Thanks in advance for clarifying this, so that I can eventually resubmit
the pie-randomization patch.
Thanks,
