Adding openssl = "0.10" dependency and running the code below (in container of #89 (comment)) also results in coredump.

fn main() {
    let _ = openssl::ssl::SslMethod::tls();
}

It seems that something happened during initialization of OpenSSL, which is invoked from startup routine, before running main() the first call to an openssl function with ffi?.

FWIW, changing the line to let _: Option<openssl::ssl::SslMethod> = None; suppresses the segfault. I think it's because openssl is not being initialized in this case.

It seems that this should be solved by upstream (maybe openssl crate).

It seems that this should be solved by upstream

Yeah I'd recommend filing a bug about it upstream. Either your distro that provides the openssl package, or the openssl-rs crate's github (it seems to be reproducible with only openssl, right?).

Given that a workaround seems to exist and the bug is in upstream, I'm closing the issue.

Should many more people hit it, I'll consider making a release with features = ["vendored-openssl"]. Until then people can:

  1. fork cargo-udeps
  2. make the change manually
  3. run cargo install --path .

This should fix the issue for them!

As far as I remember, Cargo built with x86_64-unknown-linux-musl does not work.

  • cargo-udeps built with cargo install --locked also segfaults. So the latest curl-sys released last month is probably irrelevant.
  • cargo udeps -h also segfaults, but cargo-udeps with empty fn main() {} does not.

Shell::new segfaults...?

(edit) Probably caused by libc::isatty No, atty::is works without segfault.

Which cargo-udeps version are you using? Also could you try to install a debug version of cargo-udeps and obtain a stacktrace (eg using gdb)?

seanpianka avatar seanpianka commented on July 17, 2024

Hi @est31, thanks for helping out.

  Installing cargo-udeps v0.1.18

and, how do you suggest install a debug version of cargo-udeps? Is there any other way to obtain debugging info?

@seanpianka cargo install --debug cargo-udeps should do the trick... regarding cargo not working with musl, that's interesting. x86_64-unknown-linux-musl seems to be tier 2. Is cargo available for this platform via rustup? Does that cargo work?

AFAIK, cargo works just fine with unknown-linux-musl.

Does cargo-udeps built with x86_64-unknown-linux-gnu work?

gnu is not available for my use-case/environment.

Try:

FROM rust:1.50.0-alpine3.12
RUN apk update \
    && apk add --no-cache \
        musl-dev \
        gdb \

RUN cargo --version \
    && rustup target add x86_64-unknown-linux-musl \
    && rustup toolchain install nightly \
    && cargo install --debug cargo-udeps

Edit: added openssl-dev.

I reproduced the segfault with the image. (But openssl-dev seems to be also necessary.)

Is libc_start_init called before main in Rust? (I'm not familiar with C)

from cargo-udeps.

est31 avatar est31 commented on July 17, 2024

Huh that's interesting... Maybe a bug with the openssl library/bindings then?

from cargo-udeps.

lo48576 avatar lo48576 commented on July 17, 2024

This problem can be worked around by using vendored openssl instead of alpine's one, by cargo = { version = "0.51", features = ["vendored-openssl"] } in Cargo.toml.
By this change, cargo +nightly-2021-03-09 udeps in the conitainer is able to finish successfully.

Note that apk add perl is required to build vendored openssl.

seanpianka avatar seanpianka commented on July 17, 2024

Hello, I'd like to report this bug upstream, could you help summarize the issue? "Initializing rust openssl v0.10 bindings is seg-faulting on alpine linux-musl?"

@seanpianka the bug you filed upstream looks good! (as someone who didn't reproduce it)
