Maybe you could import what is needed for the "guix environment" from an i686 machine? I would suggest to do a "guix pull --commit=0939462e3f81bc98b38bdb7610e6a80ca1cbaa1b", since this is the version already available on the machine. Andreas

I'd like to test what happens if one builds json-c on an aarch64 host
for i686.
Could we enable qemu-binfmt for i686 on an aarch64 host for me to test it?
One machine is enough--I'd just run
guix environment -s i686-linux gcc-toolchain -- gcc -o a00 -D_FILE_OFFSET=
_BITS=3Dxxx a00.c
and then later
guix build -s i686-linux json-c
on it.
a00.c:
#include <stdio.h>
#include <errno.h>
#include <assert.h>
#include <dirent.h>
#if defined( __ILP32__ )
#warning ILP32
#endif
int main() {
DIR* d;
struct dirent* ent;
d =3D opendir("tmp");
errno =3D 0;
assert(sizeof(ent->d_off) =3D=3D sizeof(off_t));
while ((ent =3D readdir(d)) !=3D NULL) {
printf("off=3D%llX, ino=3D%llX\n", (unsigned long long) ent=
->d_off, (unsigned long long) ent->d_ino);
}
if (errno)
perror("readdir");
return sizeof(off_t);
}

Wouldn=E2=80=99t such builds simply fail (as in the CM= ake > case), as opposed to succeeding but somehow producing invalid binaries? I don't know what hashing mechanism ext4 uses, but I guess the odds are not that high IF THE DIRECTORY IS RANDOM. If it's crafted by a malicious perso= n, all bets are off. However, notice that glibc can only fail out of readdir once it gets an *ac= tual* value >=3D 2**32. It's totally possible in principle to have a directory w= ith 200 entries, the first 100 of which have d_off < 2**32, and the 101st has d_off >=3D 2**32. Readdir will only stop after having given back 100 entri= es to the caller. The caller most likely will process those 100 entries. That's it, you've just forgotten to install/copy/read/whatever half the fil= es. Technically the caller could examine errno to find out that something bad happened while using readdir, but odds are that they don't (I haven't seen anyone do that in my entire career)--and also the error code they are using is undocumented[1]. So even a person who would check wouldn't expect this error value (errno =3D=3D EOVERFLOW). In short, it won't work in practice. > We can still disabled emulated builds on ci.guix.gnu.org, but let=E2=80= =99s > first make sure we understand the practical impact of this bug. We need non-emulated builds to compare. If a real ARM machine uses substitutes for anything, it probably picks up now-untrustworthy builds made by x86_64 for ARM and builds on top of those. Or don't they use substitutes? In that case everything would be OK-ish. Otherwise huge mess... [1] "man getdents64" does not list EOVERFLOW--at least not for me. --Sig_/5=gZNvCW1UBpui28Ro3bgMU Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEds7GsXJ0tGXALbPZ5xo1VCwwuqUFAl9uGX4ACgkQ5xo1VCww uqWi9wgAm4mQhsA+mCqSiaPLDJr7y7QuqAZ/xU9WjKqIbGCQHZJZyveeOr64B2OV xDuVXzn2yc/P4Ot3mMm1+EuW85FXKcIG3y7xwd5kA0+d0oSfHBQOrBru2Xw7ezMD 734V3Fh79KzHSjhL/rBrdl3dJ+nwRas5Ap5jKJpgtB15HKDqyPS1F6+Sooxmxr/J SKuEd8vwsKrS+WmDpTWJoWh1BJkcqQsIOl9rA1kk1WlYU25buysKHSdFzUmZ1EBN d/F8+O5B1/jBQM8EpEkYjG2LvgWX1oqizP9UZ9G3OZ8lM1NaYF+13hdtWtJhJMNn OwHKPnuFRI4lzqpUzMyM35MCPhHE3A== =E3hj -----END PGP SIGNATURE----- --Sig_/5=gZNvCW1UBpui28Ro3bgMU--

Sure--cmake upstream will fix it anyway and make a new release. But I now opened bug# 43591 on guix-patches in order to find all the OTHER problems this causes we didn't see yet. I already ran it on my laptop in order to find all the users trying to stick a 64-bit value into a 32-bit slot and it looks very bad--there are instances of this problem in libstdc+= +, binutils bfd etcetc. I suggest to delete all ARM substitutes that were built on x86_64 machines and disable the builders using x86_64 to build ARM stuff in the mean time. What that has built is VERY MUCH not reliable since readdir() was broken sporadically--and compilers need that :P > It doesn=E2=80=99t make sense to cross-compile from x86_64 to i686.

I'm still hoping we can skip the workaround and do the right thing instead (compiling everything with -D_FILE_OFFSET_BITS=3D64 regardless of architect= ure). I thought this matter with making everyone use LFS was settled in about 2007--but no, here we go again :( Even if we did the workaround with qemu here, that still means the kernel (via a compatibility layer) is going to lie to qemu about file offsets and directory entry hashes. That doesn't sound good for reproducibility. Also, I want to be clear that qemu is not at fault here. It's fundamentally unsound to call getdents64 and expect a value with less than 64 bits back. But that is what glibc does. Users (other packages) who use _FILE_OFFSET_BITS=3D32 (by not setting _FILE_OFFSET_BITS at all) in 2020, those are at fault. > Likewise for AArch64/ARMv7. I do not think the X86_32 compatibility layer works on aarch64, so now we h= ave a problem. That means building stuff for ARMv7 on aarch64 is not reliable = at all. The right fix is to always use "-D_FILE_OFFSET_BITS=3D64" in user space.

Looks very much like the CMake-on-emulated-hardware issue several of us
encountered before:
https://issues.guix.gnu.org/38454#3
https://issues.guix.gnu.org/42448
Glad you found an explanation!

OK.

Yes; that user-space should be built with -D_FILE_OFFSET_BITS=3D64 is also
the conclusion at
<https://sourceware.org/bugzilla/show_bug.cgi?id=3D23960#c32>.

It doesn=E2=80=99t make sense to cross-compile from x86_64 to i686. Instea=
d we
should use a native build, but an i686 one:
(package/inherit qemu
(arguments `(#:system "i686-linux" ,@(package-arguments qemu))))
Likewise for AArch64/ARMv7.
How does that sound?
Thanks,
Ludo=E2=80=99.

Hi,
I found the underlying cause of the problem with qemu transparent emulation:
* qemu transparent emulator has 64 bit registers
* the thing it's emulating has 32 bit registers
* The glibc in the distro that is running in the emulator is using getdents=
64
(on 32 bits!) and then (rightfully) checking whether d_off and the inode nu=
mber
fit into their own (32 bits/entry) struct, which they don't (the thing they=
get
from the kernel is 64 bits/entry).
See also https://lore.kernel.org/lkml/20181229015453.GA6310@HIDDEN=
ead.org/T/
for an analysis.
See also https://sourceware.org/bugzilla/show_bug.cgi?id=3D23960 for a disc=
ussion.
Least-shitty workaround: Use a 32-bit qemu (yes, a qemu compiled on 32 bit)
on a 64 bit machine for transparent emulation of ANOTHER 32-bit machine.
That way, the kernel can know that there's a 32 bit user lurking somewhere =
up
the call chain that is calling getdents64 and is not actually able to proce=
ss the
result. "The truth? It can't handle the truth."
The right fix: One could also tell all the packages in the emulated
system to use the large file size API (-D_FILE_OFFSET_BITS=3D64 and co). I=
n this
case cmake is affected--but it could be any number of things. I think that=
that
is the only good fix (we could also add a compile-time check whether <diren=
t.h>
has been included without anyone specifying -D_FILE_OFFSET_BITS=3D64--that =
would
make finding these problems a LOT easier; if possible, emit that compile-ti=
me
error only if readdir is actually called anywhere).
For the workaround, we could adapt Guix system's gnu/services/virtualizatio=
n.scm
so it uses a qemu built for the 32-bit variant of the host architecture if =
it's
emulating a 32 bit system.
So qemu could be compiled for i686 if the host is x86_64 and the emulated
system is armhf,
qemu could be compiled for armhf if the host is aarch64 and the emulated sy=
stem
is armhf and so on.
That also means that if a host system is 64 bits and DOES NOT HAVE a 32 bit
pendant target, then the emulation of a 32 bit system is going to be imperf=
ect.
One way to fix that would be to fix the kernel to accept an argument on
the getdents64 syscall (and similar ones) that tells it whether the user wa=
nts
to have 64 bit offsets or 32 bit offsets[1]. Right now, from user space, t=
hat
is only possible via process personality flags. And those would switch the
entire qemu executable over to 32 bits, which we don't want (qemu itself has
to do stuff using kernel syscalls, so it needs to be capable of 64 bits
if it itself is 64 bits). And I think that even that case is not being
handled in the kernel correctly. So this fix cannot be done.
@Ludo:
Anyway, I have a question on how to replicate what "guix build --target=3Di=
686..."
does, in the guix service definition. How can I make it use
package-cross-derivation instead of package-derivation ?
See attachment.
With the attachment and the service definition
(service qemu-binfmt-service-type
(qemu-binfmt-configuration
(platforms (lookup-qemu-platforms "arm"))
(guix-support? #t)))
in order to emulate ARM on x86_64 I eventually get:
>Building qemu-minimal for i686
(That's what I want!)
>[...]
>starting phase `configure'
>
>ERROR: pkg-config binary 'i686-unknown-linux-gnu-pkg-config' not found
pkg-config has not been cross-compiled...
That's because it's not using package-cross-derivation, I guess.

I think that "--cc" should use ,(cc-for-target) at all times.
Better this:

[1] A way for userspace to tell the kernel that is to use getdents instad of
getdents64 on 32 bits, like it used to. But they don't want to do that any=
more.
Another way would be for qemu to translate a syscall getdents64 from the gu=
est
to getdents on the host if the machine they are emulating is 32 bits. But =
that
would mean that getdents on a 64 bit host would still have to act like it's
32 bits and translate the d_off accordingly. That's not guaranteed[2].
Or even using the old readdir syscall.
[2] Linux-5.8.8:

error =3D -EFAULT;
else
error =3D count - buf.count;
}
fdput_pos(f);
return error;
}
It's not guaranteed.
