standalone installer rustc-1.70.0 (precompiled binary) segfaults in elf_machine_runtime_setup

[gyakovlev]

In gentoo we ship prebuilt rust (from standalone installers https://forge.rust-lang.org/infra/other-installation-methods.html#standalone-installers) as an alternative for users who do not with to build from source and for bootstrap purposes. Hover, one of developers is observing segfaults from the precompiled binary. If they build 1.70.0 from source - it all works fine though.

Full backtrace at the bottom.

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7fd94b5 in elf_machine_runtime_setup (profile=0, lazy=<optimized out>, scope=0x7ffff7fab4a8, l=0x7ffff7fab120)
    at ../sysdeps/x86_64/dl-machine.h:88
88	      *(ElfW(Addr) *) (got + 1) = (ElfW(Addr)) l;

I can't reproduce on my powerpc64le-unknown-linux-gnu with standalone installer at all.

[gyakovlev]

@juippis is the one with problem, hope he can provide additional details as needed.

[saethlin]

This sounds like it could be the same problem as #112275

[juippis]

Funnily enough I also first noticed the issue when attempting to build librsvg. Let me know what info you need, or if you want to merge these issues into one and me to provide the same info.

[saethlin]

What architecture is the crash happening on? I see PowerPC mentioned in the issue description, but also that you can't reproduce on PowerPC.

I tried reproducing with this:

$ docker run -it --rm gentoo/stage3

Then

cd
emaint -a sync
curl -LO https://static.rust-lang.org/dist/rust-1.70.0-x86_64-unknown-linux-gnu.tar.gz
tar xf rust-1.70.0-x86_64-unknown-linux-gnu.tar.gz
cd rust-1.70.0-x86_64-unknown-linux-gnu
bash install.sh
rustc -vV

And I get

rustc 1.70.0 (90c541806 2023-05-31)
binary: rustc
commit-hash: 90c541806f23a127002de5b4038be731ba1458ca
commit-date: 2023-05-31
host: x86_64-unknown-linux-gnu
release: 1.70.0
LLVM version: 16.0.2

(no segfault)

What's the version of your dynamic linker? Mine in the Gentoo Docker image is:

/lib64/ld-linux-x86-64.so.2 --version
ld.so (Gentoo 2.36-r8 p10) stable release version 2.36.
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.
There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A
PARTICULAR PURPOSE.

The distributed x86_64 linux rustc contains optimizations from LTO, PGO, and BOLT, and this latest release contains an LLVM version bump. So if I had to guess, the cause of this crash is a bug in those optimizations that only surfaces in uncommon but valid ld.so setup/configuration, or something else to do with the system.

If by building from source you mean just running x.py as opposed to the CI scripts and Docker images we use to build dist artifacts, that would also support this theory. x.py doesn't know about PGO and BOLT.

[thesamesam]

x86-64 for juippis' report. Gyakovlev is just saying he can't hit it on ppc64 but he's forwarding the bug.

Gentoo's build from source uses x.py.

(Sorry if a bit terse, writing on mobile!)

[juippis]

Yep, I'm on x86_64. I retraced your steps,

curl -LO https://static.rust-lang.org/dist/rust-1.70.0-x86_64-unknown-linux-gnu.tar.gz
tar xf rust-1.70.0-x86_64-unknown-linux-gnu.tar.gz
cd rust-1.70.0-x86_64-unknown-linux-gnu
bash install.sh

and rust installed with this method works! I do see the blake2b sum doesn't match with what gets installed via our rust-bin ebuild. I wonder if the manifest changed, or if the ebuild is pulling a wrong distfile?

EDIT: oh, .tar.gz vs. .tar.xz.

The -bin version installed by an ebuild is still broken on an identical container (lxc copy).

@gyakovlev

[hhoffstaette]

Of course team Gentoo is here :)
I think I found something. As the unmolested upstream package works fine, I suspected it is probably something in the Gentoo ebuild, and lo!

root>FEATURES="nostrip" emerge -v1 \=virtual/rust-1.70.0 \=rust-bin-1.70.0

It successfully rebuilds a bunch of my packages too (emlop, librsvg, rustic), except for libopenraw, which seems to be a language conformance/compiler strictness issue.
So there! Maybe another binutils bug and strip eats more than it should, or the LTO-PGO-BOLT stuff is so fragile that stripping breaks it. Probably BOLT.. ¯ \_(ツ)_/¯

[thesamesam]

Could you try STRIP=llvm-strip?

[hhoffstaette]

Could you try STRIP=llvm-strip?

Sure:

root>/usr/bin/rustc -vV
/usr/bin/rustc: error while loading shared libraries: libLLVM-16-rust-1.70.0-stable.so: ELF load command address/offset not page-aligned

:(

[gyakovlev]

so our installer for -bin package also just uses install.sh.
so stripping binaries breaks rust.
this should not happen ideally ofc. but at least I can disable stripping in this version. thanks for finding it!
I guess rustup version is not affected as it does not strip toolchains on installation.
