Changelog:

# Arti 1.1.3 — 31 March 2023

Arti 1.1.3 continues our work on onion services.  We can now parse all
of the relevant message types, build circuits as needed to target
relays, build and sign onion service descriptors, and deliver onion service
requests to our `hsclient` code.

We've also solved a few annoying bugs, made our CI more bulletproof against
certain programming mistakes, and exposed a few APIs that had been missing
before elsewhere in our code.

### Major bugfixes

- Prevent a fatal error when finding a usable consensus in a read-only
  directory store. ([#779], [!1055])

### Breaking changes in lower level crates

- Moved futures-related utilities from `tor-basic-utils` to a new
  `tor-async-utils` crate. ([!1091])
- When the `expand-paths` Cargo feature is not enabled, we now reject
  paths in our configuration containing unescaped `$` and `~` strings.
  Previously we would treat them as literals, which would break
  when `expand-paths` was provided. ([#790], [!1069])

### Onion service development

- We now have working implementations for all of the message types that Tor
  uses to implement onion services. These are included in our fuzzing, and
  are cross-validated against the C Tor implementation. ([!1038], [!1043],
  [!1045], [!1052])
- Our onion service descriptor parsing code now validates the inner
  certificates embedded in the descriptors, for parity with C Tor's behavior.
  ([#744], [!1044])
- Refactor responsibility for HS circuit management out of `CircMgr`
  ([!1047])
- Revise APIs and outline implementations for the initial parts of a state
  manager and client implementation.  ([!1034], [!1086])
- Handle requests for `.onion` addresses by routing them to our onion service
  code.  (This code does not yet do anything useful.) ([!1060], [!1071],
  [!1098])
- Our circuit implementation now has APIs needed to send special-purpose
  messages and receive replies for them.  We'll use this to implement
  onion service handshakes outside of the `tor-proto` module. ([!1051])
- Implement functionality to pre-construct and launch circuits as needed for
  onion service directory, introduction, and rendezvous
  communications. ([#691], [!1065])
- Implement code to construct, encrypt, and sign onion service
  descriptors. ([#745], [!1070], [!1084])
- More work on usable APIs for HSDir ring. ([!1095])

### Infrastructure

- Add a new `check_env` script to detect whether the environment is set
  up correctly to build Arti. ([!1030])
- We have the beginnings of a `fixup-features` tool, to make sure that our
  "full" and "experimental" Cargo features behave in the way \ 
we expect,
  and eventually to enable us to use [`cargo-semver-checks`] on our
  non-experimental features only.  This tool is not yet ready for
  use; its semantics are subtly wrong. ([#771], [!1059])
- Our CI scripts now rejects merges containing the string
  "XX<!-- look, a squirrel -->XX";
  we use this string to indicate places where the code must be fixed
  before it can be merged. ([#782], [!1067])

### Testing

- More of our tests now specify times using [`humantime`] (rather than as
  a number of seconds since the Unix epoch). ([!1037])
- Our fuzzers now compile again.
  ([53e44b58f5fa0cfa], [!1063])

### Documentation

- New example code for building a `BridgeConfig` and launching a TorClient
  with bridges, without having a config file. ([#791], [!1074])

### Cleanups, minor features, and minor bugfixes

- Our `caret` macro now works correctly for uninhabited
  enumerations. ([841905948f913f73])
- Defend against possible misuse of [`tor_bytes::Reader::extract_n`].
  This wasn't a security hole, but could have become one in the
  future. ([!1053])
- Do not ask exits to resolve IP addresses: we already know the IP address
  for an IP address. ([!1057])
- Fix a bunch of new warnings from Rust 1.68. ([!1062])
- Expose builder for [`TransportConfigList`] as part of the public
  API. ([455a7a710917965f])
- Enforce use of blinded keys in places where they are required. ([!1081])
- Add accessors for the [`Blockage`] type, so other programs can
  ask what has gone wrong with the connection to the network. ([#800],
  [!1088]).

ChangeLog:

Arti 1.1.2 — 28 February 2023

Arti 1.1.2 continues our work on onion services, and builds out more of the \ 
necessary infrastructure, focusing on backend support for the onion service \ 
directories.

We've also done a significant revision on our handling of incoming messages on \ 
circuits, to avoid a fair amount of unnecessary copying, and defer message \ 
parsing until we're certain that the message type would be acceptable in a given \ 
context. Doing this turned up several bugs, which are now fixed too.
Breaking changes in lower level crates

    The APIs for tor-cell have changed significantly, to help implement #525 and \ 
prepare for #690. This has no downstream implications outside of tor-proto.
    Our IntegerMinutes type no longer has an erroneous days() accessor. (This \ 
accessor did not work correctly, and actually returned a number of minutes!) \ 
(bb2ab7c2a3e0994bb43)
    The PartialNetDir::fill_from_previous_netdir() function has changed its \ 
argument types and semantics. (f69d7f96ac40dda5)

(Breaking changes in experimental APIs are not noted here.)
New features

    We now have the facility to give a helpful "error hint" in \ 
response to a given failure. Right now, we use this to improve the error message \ 
given for file-system permission errors, so that it suggests either changing the \ 
permissions on a directory, or suppressing the error. (#578, #579, !976, !994, \ 
!1018)
    When we log an error message from inside our code (at "info" or \ 
higher), we now make sure to log a full error report, including the cause of the \ 
error, its cause, and so on. (#680, !997)
    When receiving messages on channels, circuits, and streams, we now defer \ 
parsing those messages until we know whether their types are acceptable. This \ 
shrinks our attack surface, simplifies our code, and makes our protocol handling \ 
less error-prone. (#525, !1008, !1013, !1017)
    We now copy relay cell bodies much less than previously. (#7, ca3b33a1afc58b84)
    We have support for handling link specifier types verbatim, for cases when \ 
we need to use them to contact a rendezvous point or introduction point without \ 
checking them. (!1029)

Onion service development

    We can now parse onion service descriptors, including all encrypted layers, \ 
with support for descriptor-based client authentication. (#744, !999, !1015)
    Our network directory code now supports deriving the HsDir directory ring, \ 
to find out where onion service descriptors should be uploaded and downloaded. \ 
(#687, !1012)
    We've refactored our implementation of onion service message extensions into \ 
a single place, to save on code and avoid type confusion. (5521df0909ff7afa)
    Our internal onion-service Cargo features have been renamed to start with \ 
hs-*. We're still using onion-* as the prefix for our high-level onion-service \ 
features. ([#756], [!1033])

Infrastructure

    All our shell scripts now work when bash is somewhere other than /bin. (!990)
    Our check_doc_features script is now a little more reliable. (!1023)
    Our coverage tools now perform better checks to make sure they have all of \ 
their dependencies. (#776, !1025)

Cleanups, minor features, and bugfixes

    The internal data structures in tor-netdir now use the \ 
typed_index_collections crate to ensure that the indices for one list are not \ 
mis-used as indices into another. (!1004)
    We no longer reject authority certificates that contain an unrecognized \ 
keyword. (#752, 266c61f7213dbec7)
    Our tor-netdoc parsing code now requires the caller to specify handling for \ 
unrecognized keywords explicitly, to avoid future instances of bug #752. (!1006)
    Several internal APIs and patterns in tor-netdoc have been streamlined. \ 
(#760, !1016, !1021)
    Make extension-handling code in for onion service message decoding more \ 
generic, since we'll reuse it a lot. (!1020)
    We now kill off circuits under more circumstances when the other side of the \ 
circuit violates the protocol. (#769, #773, !1026)
    We now expire router descriptors as soon as any of their internal expiration \ 
times has elapsed. Previously, we expired them when all of their expiration \ 
times had elapsed, which is incorrect. (#772, !1022)
    We are much more careful than previous about validating the correctness of \ 
various message types on half-closed streams. Previously, we had separate \ 
implementations for message validation; now, we use a single object to check \ 
messages in both cases. (#744, !1026)
    We now treat a RESOLVED message as closing a half-closed resolve stream. \ 
Previously, we left the stream open. (!1026)

Thanks to everyone who has contributed to this release, including Dimitris \ 
Apostolou, Emil Engler, and Shady Katy.

Log message:
net/arti: Import as arti version 1.1.1

Arti is a project to produce an embeddable, production-quality implementation
of the Tor anonymity protocols in the Rust programming language.

Arti is more flexible than the C tor implementation. Unlike the C tor, which
was designed as SOCKS proxy originally, and whose integration features were
later "bolted on", Arti is designed from the ground up to work as a \ 
modular,
embeddable library that other applications can use.

Current Status
Arti can connect to the Tor network, bootstrap a view of the Tor directory,
and make anonymized connections over the network. Now that Arti has reached
version 1.0.0, we believe it is suitable for actual use to anonymise
connections.

There are a number of areas (especially at the lower layers) where APIs
(especially internal APIs) are not stable, and are likely to change them.
Right now that includes the command line interface to the arti program.

And of course it's still very new so there are likely to be bugs.
