| * | | | | | | | | hsclient: Remove no longer needed panic handling logicGabriela Moldovan2026-05-071-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `connect()` no longer panics, so we don't need it anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing this means we wont't need to go through the trouble of building a valid `Rendezvous2` cell in the tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the blinded id has changed since we cached our descriptor, it means the TP has changed, and so we can assume the new descriptor is fresher. Part of #966
| * | | | | | | | | hsclient: Store the HsBlindId alongside the HsDescGabriela Moldovan2026-05-071-4/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables us to tell whether a newly fetched descriptor's revision counter can be compared with the revision counter of our cached descriptor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C Tor calls this a "period", but "interval" is more accurate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As David mentioned in a review comment, we don't want to refetch the descriptor unless *all* introduction attempts have failed. See https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3925#note_3402810
| * | | | | | | | | hsclient: Reach out to all HsDirs if we have no descriptorGabriela Moldovan2026-05-071-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the client doesn't have a timely cached descriptor, then ignore the requery period and reach out to all the HsDirs of the service. This can, in theory, cause the client to unnecessarily query the HsDirs when its cached descriptor has expired, but this would be a very rare event, because the descriptor is long lived. I'm carving out this exception to the usual rate-limiting behavior, because I suspect having the client more eagerly reattempt the connection will be better for UX, (by the time the client's descriptor expires, the service, assuming it's still online, is expected to have published a new one, so IMO it makes sense to try to fetch it).

This rate-limiting is per-HsDir: the client will avoid querying the same HsDir more frequently than `hs_dir_requery_period`. The HsDir requery info is stored in the new `DataHsDirs` map. Part of #966

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is no longer an `&OwnedChanTarget`, so I'm renaming it accordingly.
| * | | | | | | | | hsclient: Make RelayIdFor impl generic over T: HasRelayIdsGabriela Moldovan2026-05-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new `RelayIdFor` type alias I'm about to add will need to call `RelayIdFor::{for_lookup, for_store}` with a type that isn't `&OwnedChanTarget`, so I will need these functions to take a generic `HasRelayIds`.

| * | | | | | | | | hsclient: Use Option<> combinators to get rid of branchingGabriela Moldovan2026-05-071-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I find having too many of these nested `else { None }` branches makes the overall logic harder to follow, so I changed this to use `Option<>` combinators instead.

| * | | | | | | | | hsclient: Only replace the hsdesc with a more recent oneGabriela Moldovan2026-05-071-6/+36

This was not a problem before, because we'd only ever fetch a new descriptor when our cahced one expired, but now that we refetch the descriptor on introduction NACK, we need to make sure the new descriptor is actually more recent than the one we have. The implementation is a bit convoluted because I had to avoid retaining a reference to the known-timely cached `desc` so as not to anger borrowck.

This is causing us some problems in [arti#2458], where arti frequently fails to connect to C Tor services in a chutney test net. One of the problems in #2458 is that all introduction points are NACK-ing the client's introduction requests, ultimately causing the connection attempt to fail: ``` 2026-04-23T16:25:23Z DEBUG tor_hsclient::state: HS connection failure for ijalr3vpf67zradtlaxze6pex5ypadu5qfsltn42cmhioqory6363tad.onion error=error: Unable to connect to hidden service using any Rendezvous Point / Introduction Point: Tried to make circuit to hidden service 6 times, but all attempts failed Attempt 1: Introduction point #3 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED Attempt 2: Introduction point #2 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED Attempt 3: Introduction point #1 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED Attempt 4: Introduction point #3 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED Attempt 5: Introduction point #2 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED Attempt 6: Introduction point #1 reported error in its INTRODUCE_ACK: NOT_RECOGNIZED ``` I think this is happening because the C Tor service has rotated intro points and republished its descriptor, before the descriptor's planned expiry. I believe is something that can (and does) happen, and so arti should be able to handle it gracefully. I added some more logs to arti and reran the test, and noticed the descriptor's lifetime works out to be just over 2 days (54h), which seems excessive (especially in our test net, where the voting interval is 20s and the hsdir interval is 8min). In any case, holding on to a service's descriptor for too long, and not refetching a new one, will cause the client's introduction requests to be rejected (because the service might switch intro points). I think there are at least 2 things we need to do to improve arti's handling of HS connections: * In the case of an introduce NACK (with status = `NOT_RECOGNIZED`), the client should refetch the descriptor and then retry the introduction. This behavior is not codified in the spec yet (see torspec#245), but I am told this is what C Tor does * Rethink the cached descriptor expiry calculation This commit addresses the first point. The second one seems trickier, so I have not looked into it yet.
