| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to mitigate syntax highlighting issues and a rust-analyzer bug (https://github.com/rust-analyzer/rust-analyzer/issues/10178), rename files that are included with the `include!` macro to have a `.rs` extension. Make sure the included files are outside `src/`, in order to not confuse humans and automated editing tools that might mistake them for valid Rust modules. fixes arti#381

* | | Final (?) API revisions for tor-linkspecNick Mathewson2022-08-106-60/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, each individual identity type becomes optional. The functions that expose them unconditionally are now in a "legacy" trait that only some downstream types are expected to implement. There are new convenience APIs in HasRelayIds: * to return Option<&keytype>, * to see if one identity-set contains another. This commit will break several downstream crates! For the reviewer's convenience, I will put the fixes for those crates into a series of squash! commits on this one. tor-netdir ---------- Revise tor-netdir to accept optional identities. This required some caveats and workarounds about the cases where we have to deal with a key type that the tor-netdir code does not currently recognize at all. If we start to add more identity types in the future, we may well want more internal indices in this code. tor-proto --------- In order to make tor-proto support optional identities, there were fewer changes than I thought. Some "check" functions needed to start looking at "all the ids we want" rather than at "the two known IDs"; they also needed to accommodate that case where we don't have an ID that we demand. This change will also help with bridges, since we want to be able to connect to a bridge without knowing all of its IDs up front. The protocol currently _requires_ the two current ID types in some places. To deal with that, I added a new `MissingId` error. I also removed a couple of unconditional identity accessors for chanmgr; code should use `target().identity(...)` instead. tor-chanmgr ----------- This is an incomplete conversion: it does not at all handle channel targets without Ed25519 identities yet. It still uses those identities to index its internal map from identity to channel; but it gives a new `MissingId` error type if it's given a channel target that doesn't have one. We'll want to revise the map type again down the road when we implement bridges, but I'd rather not step on the channel-padding work in progress right now. tor-guardmgr ------------ This change is mostly a matter of constructing owned identity types more sensibly, rather than unwrapping them directly. There are some places marked with TODOs where we still depend on particular identity types, because of how the directory protocol works. This will need revisiting when we add bridge support here. tor-circmgr ----------- These changes are just relatively simple API changes in the tests.
* | | Introduce a RelayIdSet and use it in place of HashSet<RelayId>.Nick Mathewson2022-08-102-11/+4
| | | | | | | | | | | | | | | This makes lookups a little more efficient. I do with that HashSet just supported this use-case, but for now this seems our best option.
* | | Teach guard restrictions about RelayId.Nick Mathewson2022-08-102-14/+26
| | | | | | | | | | | | | | | This implementation is (sadly) too copy-heavy or now, because HashSet<RelayId> can't be indexed with RelayIdRef.
* | | Use accessors in two places where tests look at specific keys.Nick Mathewson2022-08-101-3/+4
| | | | | | | | | | | | | | | | | | (It's safe to require these specific keys, since we constructed the objects for testing, and we know for certain that they contain given keys.)

| | | | | | | | | | | | | | | This method tells if two HasRelayIds contain exactly the same set of Relay identities, and is generally useful for debugging.

| | | | | | | | | | | | I believe that this was the original motivation behind #428.
* | | tor-linkspec: Refactor out traits to represent a relay's ID set.Nick Mathewson2022-08-023-8/+19
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | We want the set of identities supported by a relay to be extensible in the future with minimal fuss; we'd also like to make working with these ID sets more convenient. To handle that, this commit adds a new trait for "Something that has the same IDs as a relay" and a new object for "an owned representation of a relay's IDs." This commit introduces a similar trait for "Something with a list of SocketAddr, like a relay has." There's no owned equivelent for that, since Vec<SocketAddr> is already a thing. Closes #428.

| * Refactor and document issues with modify_hop.Nick Mathewson2022-06-173-14/+41
| | | | | | | | | | | | | | | | | | | | | | | | At the site of modify_hop, we now have a comment explaining the internal-error issue. To make the internal error less likely, we lower the modify_hop call in lib.rs into GuardSet, where it can make sure it's looking at the same filter as was used to select the guard. The function name "pick_guard_ext" is not permanent; I'm going to rename it in the next commit.
| * API-fix for extend_sample_as_needed.Nick Mathewson2022-06-172-19/+20
| | | | | | | | | | | | | | | | | | Previously, the API said "you need to call this in a loop till it returns false". We did that in one place, but not another. With the introduction of filters, forgetting to loop here becomes a bug: so instead, change the behavior of extend_sample_as_needed so it handles looping itself.
| * Remove some outdated comments.Nick Mathewson2022-06-173-18/+0
| | | | | | | | | | These all say, in one form or another, "there is no guard filtering; there is only one selection". That's now false.
| * Tweak parameters in guardmgr tests to improve testnet behavior.Nick Mathewson2022-06-171-9/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The fake network we construct for these tests is small in ways that can sometimes cause weird behavior with guard filters. We fix this by adjusting the parameters of the guard selection algorithm accordingly in the tests. With these new parameters, #491 no longer occurs. This commit also adds comments to explain why the parameters are set as they are. Closes #491.
| * GuardMgr: Support for multiple guard setsNick Mathewson2022-06-172-33/+98
| | | | | | | | | | | | | | guard-spec.txt specifies that we have multiple separate samples of guards that we can use depending on whether the filter is restrictive or not. Here we implement the rules for switching between samples.
| * Move set_filter into GuardMgrInner.Nick Mathewson2022-06-172-41/+33
| | | | | | | | | | Convert its argument type to Option<&NetDir> to better match the rest of the API.
| * GuardMgr: Function to tell how permissive a filter is.Nick Mathewson2022-06-171-0/+50
| | | | | | | | | | | | | | | | | | When we're filtering guards, we have to check whether the filter is "restrictive": if it forbids most of the guards (by bandwidth), we keep its guards separated from the main set. If it is super-restrictive, we also warn. This functionality is specified in guard-spec.txt.
| * GuardMgr: Also apply filters to fallback directories.Nick Mathewson2022-06-172-7/+12
| |
| * GuardMgr: remove disallowed addresses from returned FirstHops.Nick Mathewson2022-06-174-2/+54
| | | | | | | | | | | | | | | | Since a guard can have a bunch of addresses, and the guard is permitted if any one of those addresses is permitted, then we might decide to use a guard with some non-permitted addresses. Thus, we need to filter those addresses before returning the view of the guard as a FirstHop.
| * GuardMgr: Remove old testing filter variant.Nick Mathewson2022-06-172-21/+9
| | | | | | | | | | We don't need to restrict based on bits in the key id any longer, since we have a real filter.

| | | | | | | | | | | | | | | | | | This is apparently a new warning from clippy nightly, documented in https://rust-lang.github.io/rust-clippy/master/index.html#significant_drop_in_scrutinee . I'm not in love with the temporary variables that this warning wants me to introduce, but it does seem like a decent way to avoid some kinds of deadlock.

| * Use testing_rng() in tests throughout our crates.Nick Mathewson2022-06-022-4/+6
| | | | | | | | | | | | 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.
* | GuardMgr: Use installed netdir provider when we want a netdirNick Mathewson2022-06-071-20/+73
| | | | | | | | | | | | | | | | | | | | | | Some of our existing code optionally takes a netdir from the caller. When it doesn't give us one, use the netdir from the installed NetDirProvider. (Possibly someday we should remove the NetDir arguments entirely. I'm deferring that because there are only two APIs affected, and because making this change would force us to rewrite a pretty large mess of unit tests.)
