| * | | | Move reload_configuration method.Nick Mathewson13 days1-40/+37
| | | | | | | | | | | | | | | | | | | | Code movement only.
| * | | | reload_cfg: Refactor to use a CfgMgr object.Nick Mathewson13 days2-87/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now this just helps us keep the parts of the configuration-reloading logic in one place, and clarifies what needs to be owned by the watcher thread and what doesn't. Moving forward, this will help make the configuration something that RPC can inspect and change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no `BackwardReactor` heading, because there isn't that much to say about it (it moves `RELAY` cells in the opposite direction, and rejects RELAY_EARLY and PADDING_NEGOTIATE).

In other words, a CREATED* cell arriving on a closed circuit shouldn't be treated as a protocol violation. There are, however, a few cases where a CREATED* with an unknown CircId *is* a protocol violation (and probably *should* cause us to close down the channel): * if the CREATED* is moving in the forward direction (towards the exit), or * if we have not previously sent a CREATE* with that particular CircId As before, distinguishing these from the "closed circuit" case above would involve some tricky logic, and the benefits are unclear, while the downsides of closing a channel when we shouldn't have are significant. It seems better to just drop these cells for now. Closes #2655 [^1]: at the time of writing, we don't have timeouts for the circuit extension logic, so what I've described here cannot actually happen today. However, we *do* have a TODO for it, so the time outs I've described here will be implemented at some point

| | |_|_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An unrecognized circuit ID is not always a protocol violation, so we shouldn't close down the channel if it happens. This change makes the channel reactor drop DESTROY and RELAY cells with unknown CircIds without closing down the channel. It affects both clients and relays. Instead of dropping these unconditionally, we could have implemented some more sophisticated checks to distinguish the bogus CircIds from the CircIds of closed circuits, but it's unclear if it's worth the added complexity (see discussion in #2655). This partly addresses #2646 (an unrecognized circuit ID shouldn't cause us to close down the channel if we're a relay). This commit partially undoes the changes from 4f567e4a9432b340c2799e600c8ceb3724ad3082, which was originally intended to mitigate flooding attacks. Part of #2655

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an `unfulfilled_lint_expectations` warning. tor-proto conditionally sets a global `allow(unused)`, and if you have an `expect(unused)` field within an `allow(unused)` struct, rust seems to warn with 'unfulfilled_lint_expectations'. https://github.com/rust-lang/rust/issues/160942

It also moves http-body-util from a development dependency to a real dependency, as this makes working with hyper a lot more comfortable.

Works like a charm, as DirMgr itself implements all three of these already.
