## Triage

### FCPs

0 open T-libs FCPs.

### Critical

- [1 `rust-lang/rust` `T-libs` `P-critical` items](https://github.com/rust-lang/rust/issues?q=label:T-libs+label:P-critical+is:open)
- [[94335](https://github.com/rust-lang/rust/issues/94335)] `P-critical` *Fix for CVE\-2022\-21658 is unsafe on some file systems*
- Patch available.
- Not sure if it should be critical, since it is tier 2.

### Backports

- [2 `rust-lang/rust` `T-libs` `beta-nominated` items](https://github.com/rust-lang/rust/issues?q=label:T-libs+label:beta-nominated)
- [[94168](https://github.com/rust-lang/rust/pull/94168)] *Fix stabilization of vget\_low\_s8*
- rejected
- [[94283](https://github.com/rust-lang/rust/pull/94283)] *remove feature gate in control\_flow examples*
- The thing this fixes should've not passed CI. Mark to check why it passed CI.

### Prioritization Requested

- [1 `rust-lang/rust` `T-libs` `I-prioritize` items](https://github.com/rust-lang/rust/issues?q=label:T-libs+label:I-prioritize+is:open)
- [[94504](https://github.com/rust-lang/rust/issues/94504)] *regression: abs\_diff parameter types*
- Very small breakage, expected. Nothing to do for us right now.
- (Long term it'd be nice if we can avoid such problems, somehow.)
- the8472 will notify the crate author (thanks!)
- [1 `rust-lang/rust` `T-libs-api` `I-prioritize` items](https://github.com/rust-lang/rust/issues?q=label:T-libs-api+label:I-prioritize+is:open)
- [[94507](https://github.com/rust-lang/rust/issues/94507)] *regression: Display and Debug for ErrorKind*
* Display impl added at: https://github.com/rust-lang/rust/pull/93090
* Permitted breakage (method resolution ambiguity)
* Small scope, not a very popular crate.
* Acceptable.
* the8472 will notify the crate author (thanks again!)

### Nominated

None

### Waiting on team

- [2 `rust-lang/rust` `T-libs` `S-waiting-on-team` items](https://github.com/rust-lang/rust/issues?q=label:T-libs+label:S-waiting-on-team+is:open)
- [[88588](https://github.com/rust-lang/rust/pull/88588)] *Make feature key optional for rustc\_stable, rustc\_const\_stable attributes*
- Maybe we should keep the tracking issue number on stable attributes too.
- This PR doesn't seem to solve any actual problem. And it may make it less likely that we use an attribute that we want to
- [[94079](https://github.com/rust-lang/rust/pull/94079)] *\[Draft\] library: Move \`CStr\` to libcore, and \`CString\` to liballoc*
- Discussion on extension trait vs inherent impl.
- Maybe CStr shouldn't have any methods that result in CString. A `From` impl is better and doesn't make CString special.
- In the past, there was SliceExt, etc. but we moved away from that. We can reconsider that. But for now a lang item for this change makes most sense, and we discuss the problem of splitting methods over our crates/features later.
- Josh to summarize in a comment on the PR.

### Needs decision

- [3 `rust-lang/rust` `T-libs` `I-needs-decision` items](https://github.com/rust-lang/rust/issues?q=label:T-libs+label:I-needs-decision+is:open)
- [[87707](https://github.com/rust-lang/rust/issues/87707)] *#\[track\_caller\] for std::sync::Once*
- [[88025](https://github.com/rust-lang/rust/pull/88025)] *ScmCredentials netbsd implementation.*
- [[91004](https://github.com/rust-lang/rust/issues/91004)] *Deref documentation: Remove references to "smart pointers"*

### Regressions

None
