The broadcast channel internally calls clone on the stored value when receiving it, and only requires T:Send. This means that using the broadcast channel with values that are Send but not Sync can trigger unsoundness if the clone implementation makes use of the value being !Sync.

Thank you to Austin Bonander for finding and reporting this issue.

Release Notes

tokio-rs/tokio (tokio)

v1.38.2: Tokio v1.38.2

Compare Source

This release fixes a soundness issue in the broadcast channel. The channel accepts values that are Send but !Sync. Previously, the channel called clone() on these values without synchronizing. This release fixes the channel by synchronizing calls to .clone() (Thanks Austin Bonander for finding and reporting the issue).

Fixed

• sync: synchronize clone() call in broadcast channel (#​7232)

v1.38.1: Tokio v1.38.1

1.38.1 (July 16th, 2024)

This release fixes the bug identified as (#​6682), which caused timers not
to fire when they should.
