| * | tor-cell: Stop using write_infallibleNick Mathewson2022-07-113-37/+69
| | | | | | | | | | | | Also, stop using "expect" and "assert!" to check for errors.

| * | Rename "write" methods on tor-bytes to "write_infallible".Nick Mathewson2022-07-113-21/+21
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This comprises four renames: ``` write_onto -> write_onto_infallible write_into -> write_into_infallible write -> write_infallible writer_and_consume -> write_and_consume_infallible. ``` The rest of this branch will be concerned with replacing these `_infallible` methods with ones that return a `Result`. This is part of #513.
* / tor-cell: Derive Eq for NtorV3ExtensionIan Jackson2022-07-181-1/+1
|/ | | | Apropos clippy complaint.
* Implement a higher-level API for the ntor v3 handshakeeta2022-07-082-0/+116
| | | | | | | | | | | | | | | | | | | This implements a higher-level API for the ntor v3 handshake, in line with that exposed by the ntor handshake. It does not, however, use the existing `ClientHandshake` trait, due to fundamental differences in the handshakes (namely, that the v3 handshake can include some additional extra extension data). Currently, the higher-level API assumes circuit extension, and copies the (undocumented!) magic verification string from c-tor that indicates this usage. A rudimentary set of functions for serializing and deserializing extensions to be sent with the handshake is also included, implementing the protocol in proposal 332 § A.2. Currently, it only implements the congestion control extensions specified in proposal 324 § 10.3. part of arti#88

* Do not include error source() in display() format.Nick Mathewson2022-06-211-3/+3
| | | | | | | | | According to doc/Errors.md, and in keeping with current best practices, we should not include display an error's `source()` as part of that error's display method. Instead, we should let the caller decide to call source() and display that error in turn. Part of #323.
* Add "full" and "experimental" features to arti-client and below.Nick Mathewson2022-06-101-1/+2
| | | | | | | | | The "full" feature is a catch-all for all features, _except_: * Those that select a particular implementation (like tor-llcrypto/with-openssl) or build flag (like "static") * Those that are experimental or unstable (like "experimental-api") * Those that are testing-only.
* tor-bytes: read_nested_*: Take a closureIan Jackson2022-06-101-15/+11
| | | | | | | | | | This eliminates the possibility of writing the bug of failing to call `should_be_exhausted`. As per this discussion https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/572#note_2811464 Fixes #498

| | | | | | | | | | | | This only affects uses of thread_rng(), and affects them all more or less indiscriminately. One test does not work with ARTI_TEST_PRNG=deterministic; the next commit will fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After changes to the prop339, the domain name in an Address can only be 255 bytes max and can NOT contain nul byte(s). Unit tests had to be modified to accept this change: - Centralise msg_ip_address - Add currently-passing tests for address length - Test counted address length longer than type wants Related to #463 Signed-off-by: David Goulet <[email protected]>

* Regenerate version bump from previous commit.arti-v0.4.0Nick Mathewson2022-05-271-2/+2
| | | | | | | This commit was made by reverting the previous commit, then re-running the script I used to generate it. In theory there should be no semantic changes: only changes due to improved formatting from cargo edit.
* Semantic version changes for Arti 0.4.0 releaseNick Mathewson2022-05-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | I followed the following procedure to make these changes: * I used maint/changed_crates to find out which crates had changed since 0.3.0. * I used grep and maint/list_crates to sort those crates in topological (dependency) order. * I looked through semver_status to find which crates were listed as having semver-relevant changes (new APIs and breaking changes). * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no changes. For those crates, I incremented their patch-level version _without_ changing the version that other crates depend on. * I scanned through the git logs of the crates with no semver-relevant changes listed to confirm that, indeed, they had no obvious breaking changes. * I treated all crates that depend on `arti` and/or `arti-client` as having breaking changes. * I identified crates that depend on crates that have changed, even if they have not changed themselves, and identified them as having a non-breaking change. * For all of the crates, I used `cargo set-version -p $CRATE --bump $STATUS` (where `STATUS` is `patch` or `minor`) to update the versions, and the depended-upon versions.
* Bump versions of trivially-changed crates.Nick Mathewson2022-05-271-1/+1
| | | | | | | | | | | | | | | | | | | These crates had only clippy fixes that do not affect their behavior: tor-bytes tor-cell tor-events tor-linkspec tor-netdir tor-socksproto This crate only had the cargo-husky dependency removed, which does not affect compatibility: tor-llcrypto Since these changes have no compatibility effects, it is not necessary to bump the versions of these crates which other crates depend on.
* clippy: Use write! rather than push_str, formatIan Jackson2022-05-111-2/+3
| | | | | This does involve unwrap, but of course that can't fail unless the formats fail, which would already panic (that's implied by format!).
* Bump the version of every* crate to 0.3.0Nick Mathewson2022-05-061-8/+8
| | | | * Except for safelog and fs-mistrust, which are new.
* squash! Bump every crate's edition to 2021.Nick Mathewson2022-04-252-2/+0
| | | | | Remove all `use` statements for `TryFrom` and `TryInto`. These are now redundant in Rust 2021.
* Bump every crate's edition to 2021.Nick Mathewson2022-04-251-1/+1
| | | | | | | | | | This is an automated change made with a perl one-liner and verified with grep -L and grep -l. Some warnings are introduced with this change; they will be removed in subsequent commits. See arti#208 for older discussion on this issue.
* Add 'rust-version = "1.56"' to every Cargo.toml file.Nick Mathewson2022-04-251-0/+1
| | | | | | | This change was made automatically with a perl one-liner, and confirmed with `grep -L`. The `rust-version` field itself was introduced in 1.56.0.
* Reformat all not-yet-reformatted Cargo.toml files.Nick Mathewson2022-04-251-10/+10
| | | | | There are no semantic changes here; only formatting. This is in preparation for other changes (wrt MSRV and edition)
* Bump all arti*, tor* crates to 0.2.0Nick Mathewson2022-04-011-7/+7
| | | | | | | | Not all of these strictly need to be bumped to 0.2.0; many could go to 0.1.1 instead. But since everything at the tor-rtcompat and higher layers has had breaking API changes, it seems not so useful to distinguish. (It seems unlikely that anybody at this stage is depending on e.g. tor-protover but not arti-client.)
* tor-proto: add a backend to detect reported clock skew.Nick Mathewson2022-03-231-2/+14
| | | | | | | | | | | | | | | | NETINFO cells, which are sent in every handshake, may contain timestamps. This patch adds an accessor for the timestamp in the Netinfo messages, and teaches the tor-proto code how to compute the minimum clock skew in the code. The computation isn't terribly precise, but it doesn't need to be: Tor should work fine if your clock is accurate to within a few hours. This patch also notes a Y2038 problem in the protocol: see torspec#80. Part of #405.
