Add partial support for SSH known hosts markers #11635

hds · 2023-01-27T16:57:07Z

What does this PR try to resolve?

The SSH known_hosts file parsing in Cargo did not previously support
markers. Markers are modifiers on the lines (@cert-authority and
@revoked) which denote special behavior for the details on that line.
Lines were skipped entirely.

This silent skipping of marker lines can be confusing to a user, who
sees that their command line Git/SSH client works for some repository,
but Cargo reports that no host key is found.

This change adds support for the @revoked marker. This marker denotes
that a key should be rejected outright. It is of limited use without
@cert-authority marker support. However, if it is present in a user's
known_hosts file, then Cargo definitely shouldn't accept that key and
probably shouldn't suggest that the user add it to their known_hosts
either.

The change also adds support for detecting @cert-authority markers in
known_hosts files. These lines cannot yet be used for host key
verification, but if one is found for a matching host, the user will be
informed that Cargo doesn't support @cert-authority markers in the
error message. Additionally, the user will be advised to use the
net.git-fetch-with-cli config option to use the command line git
client for fetching crates from Git.

How should we test and review this PR?

The changes in this PR are covered by unit tests, all within
src/cargo/sources/git/known_hosts.rs.

Additionally, manual testing can be performed. For this you will need
an OpenSSH server (it doesn't need to be a Git server). I'll assume
that you have one running on your local machine at 127.0.0.1.

Setup

Create a new Cargo project and add the following line to [dependencies]:

fake-crate = { git = "ssh://127.0.0.1/fake-crate.git" }

Test missing host key: `HostKeyNotFound` (existing functionality)

Back up your known_hosts file and then remove any lines for 127.0.0.1.
Verify host key not present: ssh 127.0.0.1. SSH should tell you The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
Run cargo build
Expect error from Cargo: error: unknown SSH host key

Test `@revoked` key: `HostKeyRevoked`

Back up your known_hosts file and then remove any lines for 127.0.0.1.
Add host key: ssh 127.0.0.1 answer yes
Find all lines in known_hosts beginning with 127.0.0.1 (there may be multiple).
Add @revoked to the beginning of all lines in (3)
Run cargo build
Expect error from Cargo: error: Key has been revoked for 127.0.0.1

Test @cert-authority`(not being supported):`HostHasOnlyCertAuthority`

Back up your known_hosts file and then remove any lines for 127.0.0.1.
Run cargo build
Expect error from Cargo: error: unknown SSH host key
Check the line after The key to add is: in the error message and copy the key type (e.g. ecdsa-sha2-nistp256)
Add a line to known_hosts: @cert-authority 127.0.0.1 <key-type> AAAAB5Wm (e.g. @cert-authority 127.0.0.1 ecdsa-sha2-nistp256 AAAAB5Wm)
Run cargo build
Expect error from Cargo: error: Found a @cert-authority marker for 127.0.0.1

Additional information

Cargo doesn't currently support a few things when checking host keys. This may affect the testing described above.

Multiple host key types (OpenSSH negotiates the host key type and can support matching the one present in the known_hosts file even when it's not the preferred type of the server).
Wildcard matching of host patterns (there's a FIXME for this)

on #11577.

Thanks, this looks great! I only have some very minor style nits.

BTW, regarding this:

Multiple host key types (OpenSSH negotiates the host key type and can support matching the one present in the known_hosts file even when it's not the preferred type of the server).

We're working on that on the git2 side.

+                    return Ok(());
+                }


I believe there is an issue here. This should not early return on a key match. Otherwise the known_hosts file becomes order-dependent, particularly if the revoked key is found later in a file. I think this should only return until after all entries have been processed.

You're completely right. Nice catch!

I've fixed the issue and added a test for this case for good measure.

@Revoked

…n processed Since a @Revoked line might deny access to a key which would otherwise be accepted, we need to process all lines before we decide that a host key should be accepted.

+                    key_type: remote_key_type,

+                    remote_fingerprint: remote_fingerprint.clone(),
+                });


I think the latent_errors part should be in an else block. Otherwise a matching entry will always add a latent error. Although that won't cause any harm as it is written now, I think it would be good to avoid adding an incorrect error object.

You're right. I'm sorry about that, I made that last change without thinking enough it seems. I've fixed this as suggested now.

Note that this will be included in the upcoming Rust 1.68.2 point release, scheduled for 2023-03-28, as it's a prerequisite for #11889.

[stable] Backport GitHub RSA key revocation Backports for 1.68.2 patch release: - Use the new GitHub key: #11883 - Bump the stable version number - Fix semver check (to pass CI): #11817 - Support revocation markers: #11635 - Revoke the previous GitHub RSA key: #11889

[stable] Prepare Rust 1.68.2 This PR prepares the 1.68.2 point release, including the following Cargo PRs: * rust-lang/cargo#11883 * rust-lang/cargo#11889 The following PR was also included as a pre-requisite for backporting: * rust-lang/cargo#11635 cc `@rust-lang/release` r? `@ghost`

Pkgsrc changes: * Adjust patches (add & remove) and cargo checksums to new versions. * It's conceivable that the workaround for LLVM based NetBSD works even less in this version (ref. PKGSRC_HAVE_LIBCPP not having a corresponding patch anymore). Upstream changes: Version 1.68.2 (2023-03-28) =========================== - [Update the GitHub RSA host key bundled within Cargo] (rust-lang/cargo#11883). The key was [rotated by GitHub] (https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/) on 2023-03-24 after the old one leaked. - [Mark the old GitHub RSA host key as revoked] (rust-lang/cargo#11889). This will prevent Cargo from accepting the leaked key even when trusted by the system. - [Add support for `@revoked` and a better error message for `@cert-authority` in Cargo's SSH host key verification] (rust-lang/cargo#11635) Version 1.68.1 (2023-03-23) =========================== - [Fix miscompilation in produced Windows MSVC artifacts] (rust-lang/rust#109094) This was introduced by enabling ThinLTO for the distributed rustc which led to miscompilations in the resulting binary. Currently this is believed to be limited to the -Zdylib-lto flag used for rustc compilation, rather than a general bug in ThinLTO, so only rustc artifacts should be affected. - [Fix --enable-local-rust builds] (rust-lang/rust#109111) - [Treat `$prefix-clang` as `clang` in linker detection code] (rust-lang/rust#109156) - [Fix panic in compiler code] (rust-lang/rust#108162) Version 1.68.0 (2023-03-09) =========================== Language -------- - [Stabilize default_alloc_error_handler] (rust-lang/rust#102318) This allows usage of `alloc` on stable without requiring the definition of a handler for allocation failure.
