std::net::bind using -1 for openbsd which in turn sets it to somaxconn. #119026

trusting platform's SOMAXCONN instead of hardcoding to 128 otherwise.

I'm going to nominate for T-libs-api. This is changing the listen backlog size to the platform maximum (via -1 or SOMAXCONN) from 128 on most platforms. On Linux this has no effect; we previously changed from our current fallback default of 128 to -1 there in #97963. #55614 is tracking a general request to make this configurable, and has a comment that seems plausible in terms of not wanting to change the behavior here:

There are situations where you would rather have clients get an error than be stuck in a long queue because service is slow, so being able to specify a small maximum backlog per application is important.

(#55614 (comment))

It's not obviously the case that this is API surface area, but I think getting an opinion from the team would be useful here. Do we want to continue to land PRs which increase the backlog size to ~maximum allowed on the system? (Perhaps finished with this PR + changes in libc to refine SOMAXCONN).

devnexen · 2023-12-17T19:35:26Z

For the most part, SOMAXCONN is set to 128 anyway except linux/glibc, hurd, aix ; haiku being the only one lesser.

Amanieu · 2023-12-19T17:11:25Z

We discussed this in the libs-api meeting. We have no objections to this change: it seems like it won't cause much behavior difference, and somaxconn can generally by controlled system-wide anyways.

Fix broken build for ESP IDF due to rust-lang#119026 `target_os = "espidf"` in `libc` lacks the `SOMAXCONN` constant, but that's probably irrelevant in this context, as `UnixListener` is not supported on ESP IDF - it being a single process "OS" only. The PR just re-uses the `128` constant so that the code builds. Trying to use the listener on ESP IDF will fail with `ENOSYS`, which is fine. *UPDATE* Might not fail with `ENOSYS` - need to test what error code would be returned, but that doesn`t change anything.
