| * proto: Add a new experimental stream-ctrl feature.Nick Mathewson2023-05-221-1/+2
| | | | | | | | | | (It doesn't do anything yet. It may eventually become always-on. But for now let's make this API optional. Part of #847)

| * | proto: Make PathEntry::Virtual feature-conditional.Nick Mathewson2023-05-232-0/+3
| | | | | | | | | | | | | | | This fixes a warning when building tor-proto without the `rpc-common` feature.

| * | | rpc: Remove downgrade_owned for nowNick Mathewson2023-05-244-42/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rationale: Our weak-vs-strong design is a bit confused at the moment due to concerns about deduplication and capability semantics. It's not clear that a general "change strong to weak" method is compatible with what we want to provide.
| * | | rpc: Disable auth:get_rpc_protocol for now.Nick Mathewson2023-05-241-0/+8

| * | | rpc: Implement functionality to remove objects from a sessionNick Mathewson2023-05-245-5/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've made doing some design choices here: * Reserving "rpc" as a prefix for post-authentication functionality that is not arti-specific. * Declaring these to be methods on the session rather than methods on the objects themselves. There's a problem with defining an API to drop a weak reference; see comment in code.
| * | | rpc: fix documentation for methods in Context.Nick Mathewson2023-05-241-6/+4
| | | |
| * | | rpc: Make the top-level returned object a "session".Nick Mathewson2023-05-244-38/+67
| | | | | | | | | | | | | | | | | | | | | | | | This will make it easier to change the semantics of what exactly we return, whether it has to be/contain a client, whether you can use it to look up all the live objects, &etc.

| * | Fix a local-only CPU DoS bug.Nick Mathewson2023-05-232-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was a bug in the way that our code used our SOCKS implementations. If the buffer used for a SOCKS handshake became full without completing the handshake, then rather than expanding the buffer or closing the connection, our code would keep trying to read into the zero-byte slice available in the full buffer forever, in a tight loop. We're classifying this as a LOW-severity issue, since it is only exploitable by pluggable transports (which are trusted) and by local applications with access to the SOCKS port. Closes #861. Fixes TROVE-2023-001. Reported-By: Jakob Lell <jakob AT srlabs DOT de>
* | | tor-hsclient: Mockable: Do concrete calls with UFCSIan Jackson2023-05-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Method dispatch rules mean that if the receiver type of the actual function changes, `self.call()` can turn into a purely-recursive call which overflows the stack. Async Rust doesn't have the usual warning for this situation :-(. UFCS is clumsier but doesn't have that problem because it involves much less magical dispatch. Instead of generating a recursive call which overflows the stack, it fails to compile.
* | | tor-hsclient: Fix MockableClientCirc for ClientCirc changesIan Jackson2023-05-231-3/+3
| | | | | | | | | | | | | | | | | | ClientCirc::begin_dir_stream now takes Arc<Self>. Method resolution rules mean that this code would just recurse, leading to a stack overflow.
* | | Fix a docs reference to refer to HsClientIntroAuthKeypairIan Jackson2023-05-221-1/+1
| |/ |/| | | | | | | | | | | | | Fixes warning from cargo -o doc --document-private-items --all-features --workspace This was evidentlhy overlooked during recent replacement of unescorted private keys in the code.

| | | | | | | | | | | | I could also have stopped using `::default()` to construct this (testing-only) object, but I think it makes more sense to turn it into a non-unit object.

| | | | | | | | | | I don't love this change, but apparently we are trying for "consistency".
* | Merge branch 'escorted_25519_secrets' into 'main'Nick Mathewson2023-05-188-89/+119
|\ \ | | | | | | | | | | | | | | | | | | Refactor code not to use unescorted ed25519 secrets Closes #798 See merge request tpo/core/arti!1192
| * | hscrypto: Remove an incorrect comment.Nick Mathewson2023-05-181-5/+0
| | | | | | | | | | | | | | | (It said that we want to deprecate all unescorted secret keys; in fact, only unescorted EdDSA secrets are bad.)
| * | netdoc, hsclient: Update remaining ed25519::SecretKey usersNick Mathewson2023-05-184-25/+24
| | | | | | | | | | | | | | | | | | Fortunately, these are all in experimental code. Closes #798
| * | hscrypto: Replace ed25519 secret keys with keypairsNick Mathewson2023-05-181-42/+32
| | | | | | | | | | | | Part of #798: We no longer use unescorted ed25519 secret keys.
| * | llcrypto: Don't take or return "unescorted" ed25519 keys.Nick Mathewson2023-05-182-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per #798, we want to make sure that we never pass around an `ed25519::SecretKey`; only an `ed25519::Keypair` (or `ExpandedKeypair`). This is because, when you're computing an ed25519 signature, you have to use the public key as one of your inputs, and if you ever use a mismatched public key you are vulnerable to a nonce reuse attack. (For more info see https://moderncrypto.org/mail-archive/curves/2020/001012.html )
| * | llcrypto: Add an `ed25519::ExpandedKeypair` type.Nick Mathewson2023-05-181-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | This is like an `ed25519::Keypair`, except that instead of a `SecretKey` it contains an `ExpandedSecretKey`. We'll be using this to implement #798, where we impose a rule that there must be no "unescorted" ed25519 secret keys.

| | | | | | | | | | | | | | | | | | | | | There are a few new TODO hs comments, though, and an XXXX I'll need to fix up in the next commit. Implements #726.
| * | tor-proto: Code to construct crypto layers for virtual hops.Nick Mathewson2023-05-183-1/+42
| | | | | | | | | | | | | | | This is fairly straightforward, thanks to our existing design work on this code.
* | | tor-guardmgr, tor-proto: minor logging tweakseta2023-05-182-4/+4
| |/ |/| | | | | | | | | | | | | - We make the tor-guardmgr "We have found that {} is usable" line include the word "guard", otherwise it doesn't appear very useful to a user in safe logging mode, since the guard gets replaced with [scrubbed]. - The "Actually got an end cell..." message is downgraded to DEBUG.

| * | hs_ntor: Calculate MAC on introduce1 message correctly.Nick Mathewson2023-05-171-3/+12
| | | | | | | | | | | | | | | | | | There were two bugs here that made the behavior unlike that of C tor: we had swapped the MAC inputs, and we had forgotten to include the public key X in the input.
| * | hs_ntor: Make internal no-rng variants of the handshake functions.Nick Mathewson2023-05-171-2/+25
| | | | | | | | | | | | We'll want these so we can implement some test vectors.
