* Refactor CandidateStatus API to simplify code in descs.Nick Mathewson2022-11-022-30/+35
| | | | This removes some duplication.

* guardmgr: Refactor candidate info; add `full_dir_info`Nick Mathewson2022-11-024-30/+72
| | | | | | | Previously we always set `dir_info_missing` to `false` for new guards, since new guards could only be taken from ones that were present in the NetDir. But for bridges, we don't download their info until _after_ we have chosen them as guards.
* guardmgr: Implement Universe for bridges.Nick Mathewson2022-11-023-2/+161
| | | | | Now we can use a group of bridges as the basis for a sample of guards.
* guardmgr: Universe API should look up by ChanTargetNick Mathewson2022-11-023-14/+13
| | | | This will be necessary for bridges.
* guardmgr: take sampled guards from Universe.Nick Mathewson2022-11-023-83/+140
| | | | This is a trickier case, since we have to deal with weights.
* guardmgr: Continue porting porting code to use Universe.Nick Mathewson2022-11-022-12/+11
| | | | Two more simple cases that can use Universe instead of Netdir.
* guardmgr: Begin to decouple guards from NetDir.Nick Mathewson2022-11-023-38/+122
| | | | | | | | | | | | | | | In this and the upcoming commits I'll be changing how guards related to `NetDir` and to `Relay`. Previously, a guard could only come from (or be updated from) a `Relay` in a `NetDir`. Soon it will be able to be built from a bridge as well. To do this, I'm defining a `Universe` trait (name negotiable) that represents a set of things that may be guards. I'm going to continue extending its functionality until there are no more methods in guard.rs or sample.rs that take `NetDir`. This commit removes most of the usage of `NetDir` and `Relay` in `guard.rs`.

* guardmgr: Include PtTarget in guards.Nick Mathewson2022-11-021-8/+50
| | | | | Use a vector, since we may (someday) want to allow a Guard to have multiple PtTargets.

| * guardmgr: Use new ambiguity-tolerant contains in state handlingNick Mathewson2022-10-251-2/+30
| | | | | | | | This has subtleties; the comments try to explain them.
| * guard sample: Change semantics of `contains` to handle ambiguity.Nick Mathewson2022-10-252-10/+33
| | | | | | | | | | | | | | | | | | This is necessary for the (somewhat undesirable) lookup_ids function to return an ID that the dirmgr can actually use to report successes and failures. As noted, lookup_ids will create problems down the road when we implement relays. We should refactor it out before then.
| * Replace contains_relay with can_add_relay().Nick Mathewson2022-10-251-9/+6
| | | | | | | | | | | | To see if we can add a relay as a guard, we need a conservative test: any IDs in common with the given relay prevent us from adding it.
| * Convert guard samples to use ByRelayIds.Nick Mathewson2022-10-253-124/+193
| | | | | | | | | | | | | | | | | | | | | | | | This required a number of changes, which I've tried to document. I've taken a conservative approach to modification, and I'm not using any of the by_*_mut() functions (yet). For cases which potentially modify the whole set, I'm using into_values() and collect() to ensure that it's re-indexed correctly, even though the identities don't change. I introduce some "TODO pt-client" comments here which I will resolve in the next commit(s).

| * guardmgr: Refactor the interior of FirstHop.Nick Mathewson2022-10-244-45/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | Now it contains either an `OwnedChanTarget` or an `OwnedCircTarget`, which will let `GuardMgr` return bridges that can be used to make circuits. As part of this change, it was necessary to revise some address-modification functions that applied to filters and `OwnedChanTarget`. Now they do the smart thing, and remove only the address that are in the `ChanMethod`. This means that the addresses from HasAddrs are still accurate about which addresses the relay "has".
| * guardmgr: Hold FallbackDir in fallback::set::EntryNick Mathewson2022-10-213-43/+61
| | | | | | | | This resolves an old TODO, and will simplify our work a little.
| * guardmgr: Add bridges sample, encode sample ID in FirstHopId.Nick Mathewson2022-10-214-52/+87
| | | | | | | | | | | | | | | | | | | | | | | | The most important part of this commit is to make sure that each `FirstHopId` includes the `GuardSetSelector` from which the guard was selected. Doing this lets us be certain that when we report that a guard has succeeded or failed, we're reporting it in the right context. Additionally, this commit uses strum to make an iterator over the samples, so that we can make sure that our "for each sample" code is robust against future changes, and we don't miss the bridge sample.

* tor-guardmgr: Export BridgeParseError from toplevelIan Jackson2022-10-121-1/+1
| | | | | Callers could `use` it as `tor_guardmgr::config::BridgeParseError` but it seems unecessary to force them to.

| | | | | | | This lint exists for perf reasons, and this is rarely relevant in tests. Using double quoted str is generally cognitively less burdensome.
* Change multiplicity of ChannelMethod and addressesNick Mathewson2022-10-112-8/+14
| | | | | | | Now each `ChanTarget` has at most one `ChannelMethod`, and only `Direct` `ChannelMethods` can have multiple addresses. Closes #600.

* Begin revising HasAddr and its relationship to ChanTargetNick Mathewson2022-10-064-1/+21
| | | | | | | | | | | | | | | | | | | HasAddr used to mean "Here are addresses that I have, at which I can be contacted." But "Where (and how) can I be contacted?" is now a question for HasChannelMethod to answer. (We still need to have "HasAddr", though, so we can answer things like "what country is this relay in" and "are these relays in the same /8?") So this commit introduces: * A new trait for adding an implementation of HasChannelMethod in terms of HasAddr. * A requirement on ChanTarget that it needs to implement HasChannelMethod. There is some temporary breakage here, marked with "TODO pt-client", that I'll fix later in this branch.
