tokio::io::ReadHalf<T>::unsplit can violate the Pin contract

The soundness issue is described in the tokio/issues#5372

Specific set of conditions needed to trigger an issue (a !Unpin type in ReadHalf)
is unusual, combined with the difficulty of making any arbitrary use-after-free
exploitable in Rust without doing a lot of careful alignment of data types in
the surrounding code.

The tokio feature io-util is also required to be enabled to trigger this
soundness issue.

Thanks to zachs18 reporting the issue to Tokio team responsibly and taiki-e
and carllerche appropriately responding and fixing the soundness bug.

Tokio before 0.2.0 used futures 0.1 that did not have Pin, so it is not
affected by this issue.

CVE-2021-45710

If a tokio::sync::oneshot channel is closed (via the oneshot::Receiver::close method), a data race may occur if the oneshot::Sender::send method is called while the corresponding oneshot::Receiver is awaited or calling try_recv.

When these methods are called concurrently on a closed channel, the two halves of the channel can concurrently access a shared memory location, resulting in a data race. This has been observed to cause memory corruption.

Note that the race only occurs when both halves of the channel are used after the Receiver half has called close. Code where close is not used, or where the Receiver is not awaited and try_recv is not called after calling close, is not affected.

Fixed

v1.0.2: Tokio v1.0.2

Compare Source

Fixed

• io: soundness in read_to_end (#​3428).

v1.0.1: Tokio v1.0.1

Compare Source

This release fixes a soundness hole caused by the combination of RwLockWriteGuard::map and RwLockWriteGuard::downgrade by removing the map function. This is a breaking change, but breaking changes are allowed under our semver policy when they are required to fix a soundness hole. (See this RFC for more.)

Note that we have chosen not to do a deprecation cycle or similar because Tokio 1.0.0 was released two days ago, and therefore the impact should be minimal.

Due to the soundness hole, we have also yanked Tokio version 1.0.0.

Removed

• sync: remove RwLockWriteGuard::map and RwLockWriteGuard::try_map (#​3345)

Fixed

• docs: remove stream feature from docs (#​3335)
