|
|
|
:: Ames receives packets as Arvo events and emits packets as Arvo
|
|
|
|
:: effects. The runtime is responsible for transferring the bytes in
|
|
|
|
:: an Ames packet across a physical network to another ship.
|
|
|
|
::
|
|
|
|
:: The runtime tells Ames which physical address a packet came from,
|
|
|
|
:: represented as an opaque atom. Ames can emit a packet effect to
|
|
|
|
:: one of those opaque atoms or to the Urbit address of a galaxy
|
|
|
|
:: (root node), which the runtime is responsible for translating to a
|
|
|
|
:: physical address. One runtime implementation sends UDP packets
|
|
|
|
:: using IPv4 addresses for ships and DNS lookups for galaxies, but
|
|
|
|
:: other implementations may overlay over other kinds of networks.
|
|
|
|
::
|
|
|
|
:: A local vane can pass Ames a %plea request message. Ames
|
|
|
|
:: transmits the message over the wire to the peer ship's Ames, which
|
|
|
|
:: passes the message to the destination vane.
|
|
|
|
::
|
|
|
|
:: Once the peer has processed the %plea message, it sends a
|
|
|
|
:: message-acknowledgment packet over the wire back to the local
|
|
|
|
:: Ames. This ack can either be positive to indicate the request was
|
|
|
|
:: processed, or negative to indicate the request failed, in which
|
|
|
|
:: case it's called a "nack". (Don't confuse Ames nacks with TCP
|
|
|
|
:: nacks, which are a different concept).
|
|
|
|
::
|
|
|
|
:: When the local Ames receives either a positive message-ack or a
|
|
|
|
:: combination of a nack and naxplanation (explained in more detail
|
2019-06-29 01:27:59 +03:00
|
|
|
:: below), it gives an %done move to the local vane that had
|
2019-12-21 09:56:51 +03:00
|
|
|
:: requested the original %plea message be sent.
|
|
|
|
::
|
|
|
|
:: A local vane can give Ames zero or more %boon response messages in
|
|
|
|
:: response to a %plea, on the same duct that Ames used to pass the
|
|
|
|
:: %plea to the vane. Ames transmits a %boon over the wire to the
|
|
|
|
:: peer's Ames, which gives it to the destination vane on the same
|
|
|
|
:: duct the vane had used to pass the original %plea to Ames.
|
|
|
|
::
|
|
|
|
:: %boon messages are acked automatically by the receiver Ames. They
|
|
|
|
:: cannot be nacked, and Ames only uses the ack internally, without
|
|
|
|
:: notifying the client vane that gave Ames the %boon.
|
|
|
|
::
|
|
|
|
:: If the Arvo event that completed receipt of a %boon message
|
|
|
|
:: crashes, Ames instead sends the client vane a %lost message
|
|
|
|
:: indicating the %boon was missed.
|
|
|
|
::
|
|
|
|
:: %plea messages can be nacked, in which case the peer will send
|
|
|
|
:: both a message-nack packet and a naxplanation message, which is
|
|
|
|
:: sent in a way that does not interfere with normal operation. The
|
|
|
|
:: naxplanation is sent as a full Ames message, instead of just a
|
|
|
|
:: packet, because the contained error information can be arbitrarily
|
|
|
|
:: large. A naxplanation can only give rise to a positive ack --
|
|
|
|
:: never ack an ack, and never nack a naxplanation.
|
|
|
|
::
|
|
|
|
:: Ames guarantees a total ordering of messages within a "flow",
|
|
|
|
:: identified in other vanes by a duct and over the wire by a "bone":
|
|
|
|
:: an opaque number. Each flow has a FIFO queue of %plea requests
|
|
|
|
:: from the requesting ship to the responding ship and a FIFO queue
|
|
|
|
:: of %boon's in the other direction.
|
|
|
|
::
|
|
|
|
:: Message order across flows is not specified and may vary based on
|
|
|
|
:: network conditions.
|
|
|
|
::
|
|
|
|
:: Ames guarantees that a message will only be delivered once to the
|
|
|
|
:: destination vane.
|
|
|
|
::
|
|
|
|
:: Ames encrypts every message using symmetric-key encryption by
|
|
|
|
:: performing an elliptic curve Diffie-Hellman using our private key
|
|
|
|
:: and the public key of the peer. For ships in the Jael PKI
|
|
|
|
:: (public-key infrastructure), Ames looks up the peer's public key
|
|
|
|
:: from Jael. Comets (128-bit ephemeral addresses) are not
|
|
|
|
:: cryptographic assets and must self-attest over Ames by sending a
|
|
|
|
:: single self-signed packet containing their public key.
|
|
|
|
::
|
|
|
|
:: When a peer suffers a continuity breach, Ames removes all
|
|
|
|
:: messaging state related to it. Ames does not guarantee that all
|
|
|
|
:: messages will be fully delivered to the now-stale peer. From
|
|
|
|
:: Ames's perspective, the newly restarted peer is a new ship.
|
|
|
|
:: Ames's guarantees are not maintained across a breach.
|
|
|
|
::
|
|
|
|
:: A vane can pass Ames a %heed $task to request Ames track a peer's
|
|
|
|
:: responsiveness. If our %boon's to it start backing up locally,
|
|
|
|
:: Ames will give a %clog back to the requesting vane containing the
|
|
|
|
:: unresponsive peer's urbit address. This interaction does not use
|
|
|
|
:: ducts as unique keys. Stop tracking a peer by sending Ames a
|
|
|
|
:: %jilt $task.
|
|
|
|
::
|
|
|
|
:: Debug output can be adjusted using %sift and %spew $task's.

ames: fix lane discovery during some lane changes
We used to not accept new indirect lanes if we already have a direct
lane. This means that if Bob, with a publicly-accessible lane, changes
lanes (eg by restarting the process and getting a new port or changing
ip addresses), tries to talk to Alice, who is behind a NAT, then Bob
will try directly but fail (because Alice is behind a NAT), so he will
route the message through her galaxy. This is good -- the message gets
to Alice. However, Alice had a direct route to Bob's old lane, so she
will try to ack on that lane, which fails. She will not time out this
lane because she doesn't know that Bob isn't getting the acks (acks
don't have their own acks).
The solution is that if Alice receives an indirect lane for Bob when she
already has a direct lane, she shouldn't ignore it. If the lane is the
same as what she has, she shouldn't change anything (in particular, she
shouldn't mark it as indirect). But if it's a new lane, she should
discard her old direct lane and use the new indirect lane.

ames: don't overwrite lane if already direct
This is why basically all packets are going through the galaxies right
now. Most of the time, the flow right now is:
* talking to ~dopzod but don't know where it is, so ask ~zod to forward,
which it does
* ~dopzod responds both directly (on the origin lane) and through ~zod
* (if NAT, the direct response doesn't get back, but the one through
~zod does. Then you respond directly to ~dopzod because their lane
piggybacked on the response. ~dopzod responds both directly and
through ~zod, and the story picks up the same as if you weren't behind a
NAT)
* now you have a direct lane to ~dopzod, so all is well.
* now the duplicate response from ~dopzod through ~zod comes in (takes a
little longer because it's bouncing off ~zod), resetting your lane to
"provisional"
* since your lane is provisional, you send your next packet both
directly and through ~zod
* GOTO 2
This change says "if I already have a direct lane, don't overwrite it
with a provisional one". This way, the only way the direct lane can be
overwritten is if they stop responding on it (cleared on "not
responding; still trying").
I also added |- to +send-blob to make |ames-verb %rot less confusing.
