* tor-guardmgr: Return a BootstrapRequired error if all the sets are empty.Gabriela Moldovan2024-05-092-14/+27
| | | | | | | | | Previously, `select_vanguard` returned a `NoSuitableRelay` error if it was unable to select a relay to use as a vanguard. We now distunguish the "there are no suitable relays in the vanguard sets" (`NoSuitableRelays`) error case from the "our vanguard sets are empty" (`BootstrapRequired`) one.

* tor-guardmgr: Add a BootstrapRequired error for VanguardMgr.Gabriela Moldovan2024-05-091-0/+9
|
* tor-guardmgr: Move VanguardMgrError to a separate module.Gabriela Moldovan2024-05-092-40/+50
| | | | | This is about to grow another variant, so I'm moving it to a dedicated `err` module.
* tor-guardmgr: Remove a nonsensical TODO.Gabriela Moldovan2024-05-091-1/+0
| | | | | | The `match` below it is fine, there's no need to rewrite it. (I think this TODO is actually dupe of the the TODO above it).
* tor-guardmgr: Remove TODO about removing Vanguard abstraction.Gabriela Moldovan2024-05-091-3/+0
| | | | | I think it's alright to keep it: it gives us the flexibility to extend it later on, if needed.
* tor-guardmgr: Remove unnecessary clippy allow.Gabriela Moldovan2024-05-091-1/+0
|
* tor-guardmgr: Remove a TODO HS-VANGUARDS.Gabriela Moldovan2024-05-091-3/+0
| | | | | | This TODO doesn't really need to be implemented: we can test the `VanguardMgr` just the same without it (`GuardMgrInner` is similar, in that it doesn't mock the rng).
* tor-guardmgr: Remove dead_code allow.Gabriela Moldovan2024-05-091-1/+0

* Resolve some clippy warnings about empty rustdoc.Nick Mathewson2024-05-051-3/+1
| | | | | (In most cases, by writing the documentation; in tests, by permitting the documentation to be missing.)

* tor-guardmgr: Make remove_unlisted return the number of unlisted vanguards.Gabriela Moldovan2024-04-301-2/+4
| | | | For symmetry with remove_expired.
* tor-guardmgr: Make remove_expired return the number of expired vanguards.Gabriela Moldovan2024-04-302-20/+25
| | | | Prompted by https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/2109#note_3024672
* tor-guardmgr: Prevent misleading logs when not rotating vanguards.Gabriela Moldovan2024-04-292-2/+15
| | | | | `rotate_expired()` now only logs that it is rotating the vanguards if some existing vanguards have actually expired.
* tor-guardmgr: Make a vanguard log message more accurate.Gabriela Moldovan2024-04-291-1/+1
| | | | | We flush every time the vanguards may have changed, but we don't know for sure if they did.
* arti-client: Make vanguards non-experimental.Gabriela Moldovan2024-04-291-3/+4
| | | | This makes the vanguards feature non-experimental.
* tor-guardmgr: Add a TODO about using the vanguard consensus params.Gabriela Moldovan2024-04-291-0/+3
|
* tor-guardmgr: Make the VanguardMgr tests pass again.Gabriela Moldovan2024-04-291-14/+29
| | | | | The tests need to be updated now that the `VanguardMode` is read from the config rather than the consensus.
* tor-guardmgr: Temporarily reintroduce VanguardConfig.Gabriela Moldovan2024-04-291-35/+66
| | | | | | | | | | | | | | As discussed on #tor-dev, I'm reintroducing `VanguardConfig` for now. The `VanguardConfig` specifies what mode (full/lite/disabled) the `VanguardMgr` should run in. We currently don't have a separate modes for HS clients and HS services. We shouldn't actually *need* a `VanguardConfig` at all, so this is just a (hopefully!) short- or medium-term fix until we sort out #1382 (which might involve making breaking changes to our `reconfigure()` APIs). Closes #1272
* tor-guardmgr: Remove old TODO about making VanguardMode a VanguardParam.Gabriela Moldovan2024-04-291-3/+0
| | | | | | | | | `VanguardParams` already contains the `vanguards_enabled` and `vanguards_hs_service` `VanguardMode` params. We still intend to abolish `VanguardConfig` in favour of deriving the `VanguardMode` from the consensus params (#1382), but this is not the right place for such a TODO.
* tor-guardmgr: Remove unnecessary clippy allows.Gabriela Moldovan2024-04-293-6/+0
| | | | None of these should be unused anymore.
* tor-guardmgr: Remove unnecessary VanguardSetsTrackedMut contraption (fmt).Gabriela Moldovan2024-04-221-1/+2
|
* tor-guardmgr: Remove unnecessary VanguardSetsTrackedMut contraption.Gabriela Moldovan2024-04-222-177/+25
| | | | | | | | The VanguardMgr now unconditionally flushes the vanguard sets to disk each time there's a consensus change, and every time a vanguard expires. Prompted by https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/2090#note_3021013
* tor-guardmgr: Remove pick_{l2,l3}_relay, add l2(), l3() accessors (fmt).Gabriela Moldovan2024-04-221-20/+19

* tor-guardmgr: Make vanguard logs begin with an uppercase letter for consistency.Gabriela Moldovan2024-04-222-4/+4
| | | | | Our log messages begin with an uppercase letter in the rest of the code base.
* tor-guardmgr: Add logging around vanguard rotation.Gabriela Moldovan2024-04-222-3/+21

|
* tor-guardmgr: Derive PartialEq for VanguardSets.Gabriela Moldovan2024-04-221-3/+3
| | | | This will be useful for testing.
* tor-guardmgr: Fix vanguard doc links.Gabriela Moldovan2024-04-221-4/+4
| | | | The referenced types are no longer available in `vanguards.rs`.
* tor-guardmgr: Select an L3 vanguard in a vanguard test.Gabriela Moldovan2024-04-221-4/+3
|
* tor-guardmgr: Allow running VanguardMgr in "service mode" in the tests.Gabriela Moldovan2024-04-221-7/+7
| | | | We will soon use this to test full vanguards.
* tor-guardmgr: Make VanguardSet private.Gabriela Moldovan2024-04-221-18/+10
| | | | | | This doesn't need to be `pub(super)` anymore, `VanguardMgr` now manipulates the `VanguardSets` exclusively through `VanguardSetsTrackedMut`.
* tor-guardmgr: Load the vanguards from disk on startup.Gabriela Moldovan2024-04-221-7/+26
| | | | | | The `VanguardMgr` reads the vanguards from the vanguards state file, whether full vanguards are enabled or not. It only persists the vanguard sets to storage if full vanguards are in use.

* tor-guardmgr: Implement VanguardMgr::flush_to_storage.Gabriela Moldovan2024-04-221-10/+15
|
* tor-guardmgr: Fix vanguard expiration test.Gabriela Moldovan2024-04-221-1/+18
| | | | | | | | | | | | | | | | Since `rotate_expired()` (previously `remove_expired()`) now also replenishes the vanguard sets, we can't use `advance_until_stalled()` anymore, because `run_once()` is never be stalled in the tests (`next_to_expire` is never `None`, so `sleep_fut` is never `future::pending()`: ``` warning: MockRuntime advance_* looped >1000 (next sleep: 877560507ms) ``` Previously, `next_to_expire` was computed *before* replenishing the vanguard sets, which is why the tests could use `advance_until_stalled()`.
* tor-guardmgr: Don't try to replenish the sets unless some vanguards expired.Gabriela Moldovan2024-04-221-23/+18
| | | | | This addresses a TODO about not calling `handle_netdir_update` unconditionally each time `VanguardMgr::run_once()` runs.
* tor-guardmgr: Move vanguard set replenishing logic to VanguardSetsTrackedMut.Gabriela Moldovan2024-04-223-225/+373
| | | | | | A lot of this is code motion: the code added to `VanguardSetsTrackedMut` was copied from the `VanguardMgr` impl, so I recommend reviewing this with `git diff --color-moved=zebra`.
* tor-guardmgr: Add VanguardSetsTrackedMut for mutating VanguardSets.Gabriela Moldovan2024-04-221-0/+54
| | | | | | | | | This enables us to track when `VanguardMgr`'s `VanguardSets` is *actually* mutated. This will soon be useful because we only want to flush the `VanguardSets` to storage if we actually added or removed some relays from the set.
* tor-guardmgr: Add some accessors for VanguardSets.Gabriela Moldovan2024-04-221-0/+43
| | | | | These will be useful later, when we place the `l2_vanguards` and `l3_vanguards` from `VanguardMgr` with a `VanguardSets`.
* tor-guardmgr: VanguardSet::remove_{unlisted,expired} returns whether the set ↵Gabriela Moldovan2024-04-221-5/+14
| | | | | | | | | changed. The two removal functions now return whether any values were removed from the `VanguardSet`. Their return values are currently ignored, but will soon be used for deciding whether to flush the `VanguardSet`s to disk (if full vanguards are enabled).
* tor-guardmgr: Add VanguardMgrError variant for tor-persist errors.Gabriela Moldovan2024-04-221-0/+5
|
* tor-guardmgr: Create storage handle for storing vanguards.Gabriela Moldovan2024-04-221-3/+11
|
* tor-guardmgr: Introduce an abstraction over the two vanguard sets.Gabriela Moldovan2024-04-221-0/+19
| | | | | | | `VanguardSets` (not to be confused with `VanguardSet`) will soon be used as: * a helper for serializing the L2 and L3 `VanguardSet`s * an abstraction over the two vanguard sets
