`ClientCirc::allow_stream_requests` is now `async` and waits until the
`AwaitIncomingStream` control message is processed by the reactor.
This guarantees that by the time the `allow_stream_requests` future
resolves, the reactor is ready to process BEGIN/BEGIN_DIR/RESOLVE cells.
Previously, the client tasks from allow_stream_requests tests had to
sleep before sending the BEGIN cell to give the reactor time to process
the `AwaitIncomingStream` control message (which tells the reactor to
expect incoming BEGIN/BEGIN_DIR/RESOLVE cells on the circuit).
Fixes#994
This will enable hidden services to send `RENDEZVOUS1` messages to the
`N`th hop of the circuit rather than the `N + 1`th virtual one (which
can only used after the client and service have completed the
introduction handshake).
This also deprecates `start_conversation_last_hop`.
Closes#959
`HopNum` will be used in `ClientCirc`'s public API when we refactor
`ClientCirc::start_conversation_last_hop` to use the provided hop rather
than always using the last one.
This `sleep` is to give the reactor task a chance to process the
`AwaitIncomingStream` message. With an 100ms, this test sometimes fails
because for some reason the reactor doesn't get a chance to process the
`AwaitIncomingStream` control command before the BEGIN cell from the
client task is received. This bumps the sleep time to 200ms for now
(TODO: follow-up with an MR with a less flaky approach).
While trying to repro the issue, I found another corner case for which
I've added a TODO HSS.
This updates the reactor to call the incoming stream handler even for
streams for which we have a stream map entry of `EndSent`. If we've
sent an END message for a stream but have not yet received an END
message back from the other party, but we later receive a BEGIN from
them, it is safe to assume we cam remove the stream from the stream map
and handle the new incoming stream request.
This adds a new `AwaitIncomingStream` control message for registering an
interest in an incoming stream.
This also adds a `ClosePendingStream` control message for explicitly
closing a stream with a given END message (needed for implementing
`IncomingStream::reject`).
This adds a new `add_ent_with_id` function for adding a new entry to the
`StreamMap`. The existing `add_ent` function auto-generates a new stream
ID, which is not good if we're a hidden service, as stream IDs are
supposed to be chosen by the OP (client). When accepting a new stream,
services, exit relays, and dir auths need to use the stream ID received
in the BEGIN cell (instead of generating a new stream ID).
When accepting a new stream, hidden services, exit relays and dirauths
don't wait for a `CONNECTED` cell from the initiator.
This commit adds constructors for building `DataStream`s and
`DataCmdChecker`s that can immediately receive data cells (and don't
expect to receive `CONNECTED` cells at all).
The build found a stale private doc comment as well as an exception
that needed to be made in check_doc_features.
The check_doc_features change solidifies a decision that things marked
with cfg(fuzzing) aren't part of the documented API.
This function isn't actually needed (it's not the responsibility of
`KeyType` to encode keys).
This commit also rewrites `ArtiNativeKeystore::insert` to use the new
`as_ssh_keypair_data` function instead of `to_ssh_format`.
The `EncodableKey::to_bytes` function didn't make much sense, because
not all keys have a canonical byte representation.
This commit replaces `EncodableKey::to_bytes` with
`EncodableKey::as_ssh_keypair_data`. In the future, `EncodableKey` will
grow functions for encoding keys in other storage formats too.
Closes#965
