Segfault due to libgit2 shenanigans

[jplatte]

Describe the bug

It's a segmentation fault! The program crashes after printing a warning about being unable to find a config path. I wanted to just have it use the default config in a project where I haven't set one up yet.

To Reproduce

jplatte@jp-desktop ~/code % cargo init t
     Created binary (application) package
jplatte@jp-desktop ~/code % cd t
jplatte@jp-desktop ~/code/t (git)-[main] % cargo deny check
2021-11-26 12:48:39 [WARN] unable to find a config path, falling back to default config
[1]    18503 segmentation fault (core dumped)  cargo deny check

Expected behavior

Successfully

Additional context

This is cargo-deny 0.10.3 installed to /usr/bin through the arch linux package. Maybe it fails to mmap the default config file or something like that? Here's the package build script, it's really minimal: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=cargo-deny

[Jake-Shadle]

I am unable to repro this. The file is only loaded if it exists, in the code path where that is printed the "config file" is just an empty string, and the rest of the run doesn't know/care that there is no actual file the config was read from.

If this still occurs for you I would appreciate having a backtrace, as it stands, I feel like the warning message is maybe a red herring.

[jplatte]

Actually just recently I got the crash again, on a project with a config file so I think you're right about the red herring.

Went ahead and uninstalled the arch package / installed from crates.io and it was fixed. I will have a closer look at how the AUR package is built and where it actually crashes.

[Jake-Shadle]

Thanks!

[jplatte]

Something fishy is definitely going on. When I have both the AUR package and the cargo package installed, things work even for the AUR package. Once I remove the cargo package, things break.

I built a debug version and ran it through GDB, this is the backtrace:

[Jake-Shadle]

This looks to be an issue for others cloudflare/wrangler-legacy#1464, possibly from rust-lang/rust#83994? I'm not really sure what options are available to workaround this, but I suppose you might try pulling the fetch into the main thread and see if waiting on it there might reduce/eliminate the problem?

I've never gotten this before so it might be something that is different between versions of openssl/libgit2 on arch versus my distro, but since I can't repro it I'm going to defer to you or someone who can repro it to provide a workaround/fix.

I suppose you might try pulling the fetch into the main thread and see if waiting on it there might reduce/eliminate the problem?

What is "the fetch" here?

[Jake-Shadle]

The code in that callstack is fetching https://github.com/rustsec/advisory-db to disk to check the crate graph for advisories.

[jplatte]

Hm, I don't think I want to take the time right now to go through the code and patch cargo-deny myself, especially considering it (somehow) works when installed the easy (when developing) way.

Might revisit at some later point.

[jplatte]

I've looked into it and there's multiple lifetime transmutations going on. I wouldn't be surprised if that's related to the issue at hand.

[nightkr]

The advisory check seems to have broken with Arch's libgit2 1:1.4.1-1, even when building using cargo build.

Downgrading to libgit2 1:1.3.0-1 and cargo clean && cargo build seems to fix it.

[MarijnS95]

Same crash as @teozkr since Arch's libgit2 1:1.4.1-1, with some extra info through the recently-enabled debuginfod. No SSL crash for us, but inside the same git_remote_fetch path:

[MarijnS95]

rust-lang/git2-rs#813 A changed struct seems to be the cause this time around. Unfortunately cargo-deny can only update git2 (libgit2-sys) in parallel with crates-index and rustsec.

[Purpzie]

Until git2 can be upgraded to 0.14, adding its vendored feature in the meantime also seems to fix the issue. I haven't tested it with cargo-deny yet but it did work with cargo-edit.

[jplatte]

Maybe an alternative to fixing the problems with libgit2 (which seems pretty hard) is switching to gitoxide instead?

[Jake-Shadle]

I would be for that except there are 2 transitive dependencies on libgit2, one via cargo, and I doubt that will ever change.

[jplatte]

Hm, well I haven't seem these segfaults in cargo itself. And I wouldn't think cargo itself will never change. There's actually a tracking issue for features cargo uses in the gitoxide repo.

[Jake-Shadle]

If people are blocked by this, support for using the git cli was added in #420 which can be used to workaround this issue in the meantime.
