miri subtree update by RalfJung · Pull Request #154582 · rust-lang/rust

RalfJung · 2026-03-30T12:48:52Z

Subtree update of miri to rust-lang/miri@7662148.

Created using https://github.com/rust-lang/josh-sync.

The `_umtx_time` flags check in `read_umtx_time` used equality (`flags == abs_time`) instead of bitwise AND (`flags & abs_time != 0`) to detect `UMTX_ABSTIME`. While functionally equivalent for current valid inputs (0 or `UMTX_ABSTIME` alone), the equality check would silently treat an absolute timeout as relative if `flags` had `UMTX_ABSTIME` set alongside other bits. Additionally, unknown flags were silently accepted, whereas the FreeBSD kernel (`umtx_copyin_umtx_time()` in `kern_umtx.c`) rejects them with `EINVAL`. The fix adds validation that rejects unsupported flags and switches to the standard bitwise AND pattern used elsewhere in the codebase (e.g. `O_APPEND`/`O_TRUNC` checks in `fs.rs`).

…threads Unblock all threads with exceeded timeouts at once

This updates the rust-version file to 212b0d4.

Something seems to be taking an extra long time in #154588. Maybe it's this?
