| * | | tor-cell: Use a more generic mechanism for managing extensionsNick Mathewson2023-02-154-79/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several HS message types have an extension list type. They all use the same framing for extensions, but each of them has separate extension types and separate extension namespaces. This commit simplifies establish_intro a little, and adds support for maintaining unrecognized extension types--at the expense of some new internal code.
| * | | tor-cell: Extract establish-intro into its own module.Nick Mathewson2023-02-154-215/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the HS message types have a lot of dependent types, like extensions and options for those extensions, and so on. Except when those extensions are portable across cell types, it makes sense to put them in their own modules.

| * | | tor-proto: Push stream message parsing into the stream objects.Nick Mathewson2023-02-156-51/+88
| | | | | | | | | | | | | | | | | | | | This closes #525, and ensures, at last, that we don't parse any message that we wouldn't accept.
| * | | tor-proto: Defer parsing of messages send to half-closed streamsNick Mathewson2023-02-153-42/+94
| | | | | | | | | | | | | | | | | | | | | | | | This includes a partial solution for #769, but also turned up another bug (#774) while I was working on it. I'll close them both once I have a real solution.
| * | | tor-proto: stop reactor (and kill circuit) if meta handler failsNick Mathewson2023-02-151-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If the meta handler reports an error, then the circuit has violated its protocol, and needs to be shut down. Fixes #773.

| * | | tor-proto: Use UnparsedRelayCell to start deferring cell processing.Nick Mathewson2023-02-152-22/+43
| | | | | | | | | | | | | | | | | | | | In general, we want to avoid parsing these cells until we are fairly sure that they are something we would accept.

| * | | tor-cell: Implement {Relay,Chan}Msg for every body typeNick Mathewson2023-02-153-5/+97
| | | | | | | | | | | | | | | | | | | | This will make it ergonomic to decode a single body type without having to declare a variant that accepts only a single message.

| * | | tor-cell: Add a new UnparsedRelayCellNick Mathewson2023-02-152-2/+60
| | | | | | | | | | | | | | | | | | | | | | | | We'll use this to router relay messages on a circuit to the appropriate stream, and hand them to that stream, without parsing the message until the stream has been determined.
| * | | tor-cell: Refactor relay cells to copy much lessNick Mathewson2023-02-1511-68/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now manipulate raw relay cell bodies as (an alias for) `Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This enables us to do much less copying. It will become more important soon, as we defer parsing relay cell bodies even longer. Related to #7. We also use SliceWriter to avoid allocating a Vec<> for every relay message we want to encode, and instead encode directly into the cell.
| * | | tor-bytes: Add a new writer implementation for fixed-size objectsNick Mathewson2023-02-153-0/+125
| |/ / | | | | | | | | | | | | | | | | | | | | | Because the API assumes that many writes are infallible, this writer takes ownership of the backing object, and will only return it to you if you didn't run over the end. I'm going to use this to save some allocations in relay cell bodies

| | | | | | | | | | | | | | | | | | | | | | | | I've been running this for 5 minutes and haven't found any crashes. I'll run it for an hour or two, then add the results to the corpus repository.
| * | | netdoc: Add a feature to expose hsdesc inner doc parsersNick Mathewson2023-02-145-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to fuzz these parsers, but there's no currently way to get at the parsers for inner documents without going through a lot of encryption. (Coverage-guided fuzzers are powerful, but they can't find SHA3 preimages.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There will be two call sites to demonstrate it. Eventually maybe this will want to be in tor-basic-utils, since it doesn't depend on any of the tor-netdoc types. But it would be sensible to wait until the situation with PeekableIterator and Itertools is improved. For now we make this #[doc(hidden)] to avoid it becoming part of our stable API.
| * | tor-netdoc: Provide NetDocReader::into_iterIan Jackson2023-02-101-0/+7
| | | | | | | | | | | | | | | This will avoids some hairy borrowck disasters when we try to use iterator adapters.
