FCP: Drop support for FreeBSD 10 and 11 from std rust#89058
Rust toolchain update: Update FreeBSD toolchain to 12.3 rust#97944

@devnexen Please resolve the merge conflict.

-        Some(_) | None => set_cfg("freebsd11"),
+        Some(12) if libc_ci => println!("cargo:rustc-cfg=freebsd12"),


This looks like a merge conflict. You should use set_cfg instead of println!

-// APIs that were changed after FreeBSD 11
-
-// The type of `nlink_t` changed from `u16` to `u64` in FreeBSD 12:
-pub type nlink_t = u16;


All of the stuff that was in this file should now be moved into freebsdlike/freebsd/mod.rs For example, move all three nlink_t definitions from freebsd{12,13,14}.rs into that file.

I started a conversation on Zulip to see how people feel about this.

This is basically 100% conflicted, but @devnexen would you be up for rebasing this?

EOL was 5 years ago so I can't imagine anyone would object at this point.

I haven't looked through this in detail yet but the changes look correct. @asomers would you be able to review?

In theory I agree with this. I'll try to review it next Saturday. We'll want to run a few dozen crates' test suites with this change, too.

These are the only two problems I've found in my testing so far. But that begs the question: how did you test these changes?

Did you really mean to remove this function? I think you should just remove the link_name instead. The function is definitely needed.

This should be u64. Otherwise stat is broken on x86.

Suggested change

pub type ino_t = c_ulong;

pub type ino_t = u64;

Your latest changes fix the two bugs that I found. What about you? How did you test these changes?

devnexen · 2025-09-07T20:14:59Z

I test within a VM the vast majority of time, sometimes when I can t I look at freebsd sources and count on CI to see. Not ideal I know.

asomers · 2025-09-07T20:28:10Z

But what did you do within that VM? What projects did you test? How did you patch them to use libc main branch?

devnexen · 2025-09-07T20:32:01Z

Usually, I just do cargo test --manifest-path libc-test/Cargo.toml. I did not try to use in any project.

For a change like this, that really isn't sufficient. You need to run the test suites of a selection of other crates, patched to use this branch of libc.
