* | tor-config: Support watching dirs for files with a given extension.Gabriela Moldovan2024-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This also fixes a couple of issues with the previous implementation: * it enables you to watch for more than just one file/extension per directory (each directory now has a list of filters. If any of the filters apply to the path contained in the notify::Event, the `FilterWatcher` notifies the listeners * it removes the list watched files from `FileWatcher`. This makes things a lot simpler to grok: essentially, the file watcher only ever watches directories, notifying if an "interesting" file was changed (in our case, the interesting files are files that have a relevant extension, such as `.auth`, or specific configuration files, as specified by `ConfigurationSources`).
* | tor-config: Make FileWatcher use an opaque channel type.Gabriela Moldovan2024-08-211-89/+106
| | | | | | | | The `FileWatcher` now uses a `postage::watch` channel under the hood.
* | tor-config: Give FileWatcherBuilder a handle to the runtime.Gabriela Moldovan2024-08-211-5/+6
| | | | | | | | | | The event handler will soon be made async, so we need a handle to the runtime.
* | tor-config: Move FileWatcher to tor-config.Gabriela Moldovan2024-08-211-185/+22
| | | | | | | | | | | | | | | | | | For the most part, this is just code motion. The only change here is that `prepare` is no longer a method on `FileWatcher`. This decouples `FileWatcher` from `ConfigurationSources`, enabling us to use it to watch files and directories that aren't configuration.
* | arti: Update outdated FileWatcher docs.Gabriela Moldovan2024-08-211-5/+1
|/ | | | | The `FileWatcher` doesn't contain the channel for receiving events anymore, and `FileWatcher::event_matched` was removed at some point.
* Merge branch '1144-std-backtrace' into 'main'David Goulet2024-08-121-5/+3
|\ | | | | | | | | | | | | Use std::backtrace instead of backtrace crate Closes #1144 See merge request tpo/core/arti!2301
| * Match previous backtrace formattingRobin Leander Schröder2024-08-081-2/+2

| * Use std::backtrace instead of backtrace crateRobin Leander Schröder2024-08-011-3/+1
| | | | | | | | | | Removes resolve_backtraces from rtmock since it is no longer needed as stdlib's backtraces automatically lazily resolve without needing a &mut.
* | arti: Add the restricted_discovery configuration to the example config.Gabriela Moldovan2024-08-052-9/+94
| | | | | | | | This also adds a test for it.

* | arti: Avoid using the now-deprecated arti_client constant.Gabriela Moldovan2024-08-051-2/+2
| | | | | | | | We can just used `build_for_arti()` here.
* | Have `arti hss onion-name` error if it doesn't print the onion nameKunal Mehta2024-08-011-3/+5
|/ | | | | | | There are two error cases where the onion name isn't printed, but previously returned `Ok(())`. It now returns an error to exit with a non-zero status code.

|
* arti: Gate the hsc subcommand behind the keymgr feature.Gabriela Moldovan2024-07-102-4/+4
| | | | | | | | | | | The `arti hsc` subcommand can't run without keymgr support. Previously, it relied on `tor-keymgr/keymgr` being enabled indirectly by its dependencies, via the `experimental` feature. We need to be able to enable this feature in `arti` without relying on `experimental` (because `arti hsc` will eventually be made non-experimental). Part of #1487
* tor-hscrypto: Remove unnecessary Display wrapper.Gabriela Moldovan2024-07-081-1/+1
| | | | | | | | | | | I don't think we need a separate wrapper type for displaying `HsClientDescEncKey` keys in the "C Tor format" (`<auth-type>:<key-type>:<base32-encoded-public-key>`). I think this should be the canonical string representation of `HsClientDescEncKey`, so I'm removing the `display_authorized_client` function and corresponding `DisplayAuthorizedHsClientDescEncKey` wrapper type.

* arti: Rewrite the hsc prepare-service-discovery-key command.Gabriela Moldovan2024-06-271-10/+30
| | | | | | | The `arti hsc prepare-service-discovery-key` command is now `arti hsc get-key [--key-type=service-discovery]`. Prompted by https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/2212#note_3042903
* arti: Add an arti hsc subcommand.Gabriela Moldovan2024-06-273-0/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an experimental `arti hsc` subcommand for managing client state and keys. Currently, it only supports the `prepare-service-discovery-keys` operation described in #1281 and `doc/dev/notes/client-auth.md`. A note on terminology: I am referring to services that encrypt the second layer of their descriptor as running in "restricted discovery" mode (because they can only be discovered, i.e. have their IPT points found out, by a set of authorized clients). The corresponding client "auth" keys, being the keys that enable the client to find out the list of intro points, pow-params etc. of the service, are referred to as service "discovery keys". Alternative names I considered: * extra descriptor encryption: accurate, but overly technical. IMO, the CLI should be accessible to users who aren't familiar with the nitty-gritty of the protocol * shielded mode: good, but slightly misleading. Calling it "shielded mode" makes it sound like a universally desirable "extra protection" that should almost always be enabled (which is not the case). Seeing `shielded_mode = off` in the config might be worry operators that don't fully understand what "extra descriptor encryption" or "shielded mode" means * restricted mode: slightly inaccurate. It implies this mechanism is a good substitute for conventional service-side authentication, which it isn't (because client authorization isn't instantaneous) Closes #1281

| | | | | | | | | | | | | | | | | | | | Add the optional non default feature flag "relay" that will be used to enable relay support of arti. This commit also adds the "relay" subcommand to arti binary conditionnal on the feature flag in order to have a place holder starting point. Signed-off-by: David Goulet <[email protected]>
* | RPC: Use RPC methods instead of the "ClientConnectionTarget" trait.Nick Mathewson2024-06-113-30/+116
|/ | | | | | | | | | | | On its own, this might not seem like a huge improvement, but it will later let us implement these RPC methods for types that can't reasonably implement ClientConnectionTarget. It also serves as a proof of concept that special-method invocation can actually work, so that we can build things like this in cases where introducing a trait isn't practical. Closes #1427
* rpc: Make RpcMgr::lookup_object return context along with object.Nick Mathewson2024-06-101-0/+1
| | | | The context will make it possible to invoke rpc methods.

* RPC: Give error from RpcMgr::new if method name is sufficiently bad.Nick Mathewson2024-05-141-1/+1
| | | | | (We don't give an error about unrecognized namespaces (for now), since we have no way to opt in to them.)
* RPC: Enforce method name format.Nick Mathewson2024-05-141-0/+29
| | | | | | | | | | | | We need to do this carefully, since we want our system to be extensible with new namespaces. First, when we are constructing an RpcMgr, we _warn_ about any method names that are misformed. Second, we add a test in the `arti` crate to fail if any method names are invalid. This will only catch method names in crates that `arti` depends on.
* RPC: Use a slightly less awful workaround in socks.rsNick Mathewson2024-05-141-20/+34
| | | | | | | | | | | | | | | | | The problem was that Rust won't let us say ``` type ConnTarget<R> = Arc<dyn ClientConnectionTarget>; ``` because the R parameter wasn't used. Previously we solved this by using a macro instead of a type definition, which is ugly. I had been thinking previously I would need to declare some kind of additional wrapper type, and had shrunk from the verbosity. But @diziet pointed out that I could just use a 2-tuple unconditionally. It's still not beautiful, but it is less hideous than before.

* RPC: RpcDataStream type to act as a "stream-shaped hole"Nick Mathewson2024-05-141-0/+1
| | | | | | | | | The application creates these, using a new-stream-handle RPC command, on an object that can actually create streams. Then later, the application provides the (global) identity of one of these objects when it's making a SOCKS connection. This causes the object to take hold of a `DataStreamCtrl`.
* RPC: Add a trait that can be the target of SOCKS requestsNick Mathewson2024-05-121-18/+34
| | | | | | | | | | | | (These will later become objects that can receive any application request, once we have HTTP connect.) For now, Session and TorClient implement this trait; but soon there will be a new type to hold on to the created DataStreamCtrl. There are some XXXXs here, marking code that is too ugly to live. I should fix it before I merge this branch.
