2021-05-12conn: MetricsPort listener is a listener portDavid Goulet
The connection type for the listener part was missing from the "is connection a listener" function. This lead to our periodic event that retries our listeners to keep trying to bind() again on an already opened MetricsPort. Closes #40370 Signed-off-by: David Goulet <dgoulet@torproject.org>

This uses a heuristic that came up after a discussion with David. I'm leaving this as a separate commit so that it can be discussed further if needed.

(If you need to do this in an older version you can just set DormantClientTimeout to something huge.) Closes #40228.

2021-02-22relay: Remove dirport reachability self testDavid Goulet
Regular relays are about to get their DirPort removed so that reachability test is not useful anymore Authorities will still use the DirPort but because network reentry towards their DirPort is now denied network wide, this test is not useful anymore and so it should simply be considered reachable at all time. Part of #40282 Signed-off-by: David Goulet <dgoulet@torproject.org>
2021-02-19hs-v2: Removal of service and relay supportDavid Goulet
This is unfortunately massive but both functionalities were extremely intertwined and it would have required us to actually change the HSv2 code in order to be able to split this into multiple commits. After this commit, there are still artefacts of v2 in the code but there is no more support for service, intro point and HSDir. The v2 support for rendezvous circuit is still available since that code is the same for the v3 and we will leave it in so if a client is able to rendezvous on v2 then it can still transfer traffic. Once the entire network has moved away from v2, we can remove v2 rendezvous point support. Related to #40266 Signed-off-by: David Goulet <dgoulet@torproject.org>

2021-02-08conn: Properly close MetricsPort socket on EOFDavid Goulet
Handle the EOF situation for a metrics connection. Furthermore, if we failed to fetch the data from the inbuf properly, mark the socket as closed because the caller, connection_process_inbuf(), assumes that we did so on error. Fixes #40257 Signed-off-by: David Goulet <dgoulet@torproject.org>

2021-01-12hs-v3: Require reasonably live consensusDavid Goulet
Some days before this commit, the network experienced a DDoS on the directory authorities that prevented them to generate a consensus for more than 5 hours straight. That in turn entirely disabled onion service v3, client and service side, due to the subsystem requiring a live consensus to function properly. We know require a reasonably live consensus which means that the HSv3 subsystem will to its job for using the best consensus tor can find. If the entire network is using an old consensus, than this should be alright. If the service happens to use a live consensus while a client is not, it should still work because the client will use the current SRV it sees which might be the previous SRV for the service for which it still publish descriptors for. If the service is using an old one and somehow can't get a new one while clients are on a new one, then reachability issues might arise. However, this is a situation we already have at the moment since the service will simply not work if it doesn't have a live consensus while a client has one.

2020-10-06Rename `OUTBOUND_ADDR_EXIT_AND_OR` to `OUTBOUND_ADDR_ANY`.Alexander Færøy
This patch renames the enumeration value in `outbound_addr_t` from `OUTBOUND_ADDR_EXIT_AND_OR` to `OUTBOUND_ADDR_ANY` since with the arrival of `OUTBOUND_ADDR_PT` it no longer makes sense to call the fallback value for "Exit and OR". Instead we rename it to "any". See: https://bugs.torproject.org/5304

2020-09-01conn: Remove assert on new listener connection when retryingDavid Goulet
Opening a new listener connection can fail in many ways like a bind() permission denied on a low port for instance. And thus, we should expect to handle an error when creating a new one instead of assert() on it. To hit the removed assert: ORPort 80 KeepBindCapabilities 0 Start tor. Then edit torrc: ORPort <some-IP>:80 HUP tor and the assert is hit. Fixes #40073 Signed-off-by: David Goulet <dgoulet@torproject.org>

2020-08-05Replace several C identifiers for ticket 18106.Nick Mathewson
We used to have a single boolean, "FascistFirewall". Ages ago, in tickets #17840 and #9067, we added an improved "ReachableAddresses" mechanism. It's time to rename related identifiers in the code for consistency. This closes #18106.
