| * | channel padding: Add doc commentary with the channel padding planIan Jackson2022-08-162-0/+27
| | | | | | | | | | | | | | | | | | | | | Much of this does not exist yet. It will do by the end of this branch. Expand a doc note for ChannelsParamsUpdates too.

| * | channel: Centralise Channel::send_controlIan Jackson2022-08-161-14/+16
| | | | | | | | | | | | | | | | | | Replaces 4 open-coded call sites. I am going to add one more.
| * | tor-proto: padding::Parameters: use impl_standard_builderIan Jackson2022-08-163-7/+5
| | | | | | | | | | | | | | | | | | | | | This is more standard. It also provides the ::build() method. This isn't a config type, and build failures ought not to happen, so we use Bug for the error.
| * | arti-client: TorClient constructor: add a blank lineIan Jackson2022-08-161-0/+1
| |/ | | | | | | | | The rustfmt-mandated different formatting of these two very similar blocks is bad enough, without them being smooshed together.

| * Mark some circuit-building errors as "transient".Nick Mathewson2022-08-162-15/+71
| | | | | | | | | | | | | | | | | | | | | | | | A "transient" error is one that does not indicate a true failure, but rather an _expected_ need to retry. When we hit one of these, we do not count it against the total number of permitted failures. (We do impose a higher limit on "real failures plus transient failures", though, to prevent infinite loops in the event of a programming error. Closes #517.

| * | arti: Add support for process hardeningNick Mathewson2022-08-157-3/+88
| |/ | | | | | | | | | | | | | | | | | | | | | | | | This is a compile-time feature with an associated configuration flag, both enabled by default. When it's turned on, hardening prevents the arti process from dumping core or being attached to by low-privileged processes. (This is a defense-in-depth measure, not an absolute way to prevent attacks. For more information, see [`secmem_proc`](https://docs.rs/secmem-proc/0.1.1/secmem_proc/).) Closes #364.

| * arti: Move most public APIs behind `experimental-api`.Nick Mathewson2022-08-1110-12/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The remaining unconditionally public APIs are those related to our configuration objects, and the main_main() API. The rationale for making main_main() public is to have an actual entry point. The rationale for making the config APIs public is: 1. We really do intend for others to be able to read our configuration files using this API. 2. The structure of our configuration files is already part of our interface. Closes #530.
| * arti: Add a feature flag for dns-proxy.Nick Mathewson2022-08-112-3/+14
| | | | | | | | | | | | | | It remains on-by-default, so users shouldn't notice a difference, but it may help when we want to save a few bytes of binary size. Closes #532

| * | tor-congestion: implement the RTT estimation algorithm from prop#324eta2022-08-118-0/+530
|/ / | | | | | | | | | | | | | | | | | | | | This commit implements the round-trip-time estimation algorithm from Tor proposal 324, validating the implementation against the test vectors found in C tor. (Note that at the time of writing, the new test vectors may not be committed to C tor yet, but they will be soon.) This also adds the necessary consensus parameters to `NetParameters`. Some of them have been renamed in order to (hopefully) make them more understandable.

| * | tor-proto: Add a comment about the tor-proto layer.Nick Mathewson2022-08-101-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | We want to clarify that the tor-proto crate should only know _how_ its objects behave, not _why they behave that way_. (In other words, we can have a "padding strategy" setting on a channel, but not a "general usage" setting.) Closes #531.

|/ / | | | | | | | | | | | | | | Now we have bus>1 ownership of the crate name `shellexpand`. I have made a release, and retired `shellexpand-fork`. The new shellexpand release switches to a (quite similarly) unforked version of `dirs`.

| * | tor-proto: Replace SecretBytes with SecretBuf.Nick Mathewson2022-08-018-63/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does not yet make sure that `SecretBuf` is used where it _should_ be, but at least it ensures that most uses of `SecretBytes` will indeed act as intended, and make sure that whatever they contain is zeroized. It requires some corresponding changes to method calls for correctness and type conformance.
| * | New SecretBuf type in tor-bytesNick Mathewson2022-08-015-0/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | This Writer is a simple wrapper around `Vec<u8>` that makes sure that its contents are cleared whenever they are dropped _or reallocated_. The reallocation is the important part here: without that, we risk not zeroizing the first allocation of the buffer.
