Gabriela Moldovan e06fc04b0b llcrypto: Explain what we need the ed25519->x25519 conversion for. 2023-06-27 19:23:42 +01:00
Gabriela Moldovan fa6290c0cc llcrypto: Document how convert_ed25519_to_curve25519_private computes the key. 2023-06-27 19:23:42 +01:00
Gabriela Moldovan 7ecb2221a0 llcrypto: Add note about bumping x25519-dalek and clamping.
This adds a TODO explaining how convert_ed25519_to_curve25519_private
will need to be audited when we upgrade to the latest x25519-dalek.

This also adds a `debug_assertions` and a test that ensures
`StaticSecret::from` is clamping the input (when we bump x25519-dalek,
the assertions will fail, as the latest version doesn't do clamping in
StaticSecret::from).

Gabriela Moldovan 1fe15c5012 llcrypto: Document ed25519->curve25519->ed25519 conversion behaviour. 2023-06-27 19:23:42 +01:00
Gabriela Moldovan 47606ad881 llcrypto: Implement ed25519_to_curve25519_private conversion.
In `ArtiNativeKeyStore`, private keys are stored in OpenSSH format.
However, `ssh-key` (the crate we use for parsing OpenSSH keys) doesn't
support x25519 keys. As a workaround, this type of key will stored
as ed25519 and converted to x25519 upon retrieval.

This commit implements the `convert_ed25519_to_curve25519_private`
conversion function (needed by `ArtiNativeKeyStore` to support x25519
keys).

pinkforest 4be2e3ce0f Back down x25519-dalek to 2.0.0-pre.1 from 2.0.0-rc.2
=========================
Notes from nickm:

(This differs from pinkforest's original MR: It removes the
Cargo.lock changes and the version bump on tor-llcrypto.)

Minimal Cargo.lock changes from downgrade.

(These are exactly those changes generated by running "build" and
"test".)

There are several reasons to do this:

  * It's best to bump all of our dalek dependencies at once to rc.3
    or later, rather than the piecemeal approach we've been stuck
    with so far.

  * We don't want to do this bump right now, since there are some
    tricky questions about clamping we need to figure out (see
    #808), and we need to make sure we get them right, and we're in
    a distracted this week.

  * We _do_ need to move away from 2.0.0-rc.2 right now, since
    it was causing a failure in `cargo install arti`, and then it
    got yanked.

Thanks to pinkforest for helping us out here and explaining all of
this!

Fixes #926.

Add Channel expiry info in ChanMgr docs 2023-06-27 18:24:56 +05:30
Ian Jackson 062b7e7ced tor-hsclient: Increase some timeouts
1. Fix a use of 10ms that should have been TIMEOUT_SLOP.
2. Increase BODGE_YIELD by a factor of 5.

Now this test should tolerate being hung up for 125ms.  I am hoping
that this will fix the CI failure
  https://gitlab.torproject.org/Diziet/arti/-/jobs/302457
which fails at the line comparing circuit1 with circuit2a.
(I can't repro that locally.)

Ian Jackson 355e65003c tor-hsclient: impl Debug by hand for MockCirc
The provided impl for Mutex is hopeless: it prints just some internal
flags and doesn't acquire the mutex for printing purposes.

At some point we might want to factor this out as a general function
on `Arc<Mutex<...>>` but not now.

Nick Mathewson 6313f0513e netdoc: Remove dead_code exception; add accessors.
This commit removes some actual dead code and additionally adds some
minimal accessors to HsDesc to expose some of its properties.  (I'm
trying to keep these minimal since it's not yet clear whether we
want to expose more detail here.)

Here we also make StoredHsDescMeta a conditional type that's only
present when the new "hs-dir" feature is enabled.  Neither relays
nor clients need this: Only HsDirs will need it, when we finally
implement relays.

Nick Mathewson 30124acbc5 arti-client: Mark DirProviderBuilder Send+Sync;

This isn't a semver break, but only because DirProviderBuilder is
marked with `experimental-api`.

The dummy key manager impl from `arti-client` will be moved to

`tor-keymgr` which will eventually be used to choose between the real
key manager API and the dummy one.

Nick Mathewson dbd2552178 netdoc: Introduce HsDescError
For higher-level HsDesc-related functions, this type indicates where
exactly an error occurred.  It lets us distinguish decryption errors
from parsing errors, and attribute responsibility to the hsdir, the
onion service, or the user's lack of encryption.

This lets us remove some just-introduced complexity in
tor-hsclient.

Gabriela Moldovan f633e41380 keymgr: Remove Error::NotFound, update KeyMgr, KeyStore APIs.
This removes the `NotFound` `tor_keymgr::Error` variant. Since `KeyMgr`
and `KeyStore` users will need to be able to distinguish between "not
found" errors and other I/O errors, this also changes the return types
of the `get()` and `remove()` functions of `KeyStore` and `KeyMgr`,
which now return `Ok(None)` instead of `Error::NotFound`.

This makes the `KeyStore` API consistent with `KeyMgr::get`, which
already has a return type of `Result<Option<K>>` (rather than
`Result<K>`).

This also prepares us for #901, which will make key store errors
opaque. Without this change:
  * we'd have to create a `struct NotFoundError;` error type. Its
    `HasKind` impl would need to return a new
    `ErrorKind::KeyStoreErrorNotFound` `ErrorKind` variant
  * callers would have to match the `error_kind()` of the error to
    figure out whether  the key simply can't be found
    (`ErrorKind::KeyStoreErrorNotFound`), or if something went wrong
    (any other `ErrorKind`).

Given the above, I think `Result<Option<()>>` makes for a more ergonomic
API.

Gabriela Moldovan 521ba309cc keymgr: Remove unnecessary condition.
We don't need to special-case `NotFound` errors because
`ssh_key::PrivateKey::from_openssh` doesn't read from disk (so it
shouldn't be returning `NotFound` errors in the first place).

Previously, this condition made sense because we were using
`ssh_key::PrivateKey::read_openssh_file` instead of
`ssh_key::PrivateKey::from_openssh`, which _does_ read from disk. This
condition should have been removed in !1263 (the refactoring where we
switched to `from_openssh`).

(Also, after #901 is implemented, we probably won't have an
`Error::NotFound` error anymore).

  maintenance utility in the C-tor codebase).
- We embed a copy of C-tor's databases with the crate and use
  `include_str!` to ship them with the binary, bloating its size
  somewhat.
  - This does, however, solve the problem of figuring out how to
    distribute these.
  - The plan is to gate this functionality behind a feature flag anyway,
    so the cost should be nil unless explicitly opted into.

Gabriela Moldovan 8202be3cfe arti-client: Make some of the dummy KeyMgr impls return an error.
`insert` and `remove` should return an error rather than `Ok(())`, as
`Ok(())` implies the key was stored/removed, which is impossible in the
no-op implementation.
2023-06-20 13:33:51 +01:00
Gabriela Moldovan 02c36dabd7 arti-client: Add more dummy keymgr APIs.
This will help us reduce the number of `#[cfgs(...)]` from `client.rs`

Gabriela Moldovan 95e4021ed8 arti-client, keymgr: Introduce Mistrust settings and enforce FS permissions. 2023-06-20 13:29:10 +01:00
Gabriela Moldovan be5c911ac8 arti-client: Temporarily ignore key store errors.
We currently initialize the `ArtiNativeKeyStore` with a dummy root dir,
so when `ArtiNativeKeyStore` starts validating directories, this code
will start to fail. Let's preemptively ignore any errors coming from
`ArtiNativeKeyStore::new`. This is temporary and will be removed when we
introduce the key store config (and a real default value for the
keystore root dir).

Gabriela Moldovan 6837dbce58 keymgr: Add an error variant for fs_mistrust errors.
This will be useful later, when `KeyMgr` will start validating
permissions and paths.
2023-06-20 13:29:10 +01:00
Gabriela Moldovan 01b43f7f26 keymgr: Add a FsErrorSource to Error::Fs.
In the future, the potential causes of an `Error::Filesystem` error will
include permission errors as well as other errors (not just
`io::Error`s).

The last piece here is removing some needless keygen from the
tests.  This causes the test output (using the deterministic PRNG)
to change.

Nick Mathewson 25db56777c Lower tor-proto::util::ct::lookup to tor-llcrypto
This is mostly code movement; you may want to review it with
`--color-moved`.

I'm doing this so we can also use the function in netdoc for
looking up hsdesc authentication.

2023-06-16 12:24:05 -04:00
Nick Mathewson 3c824fe302 netdoc::build remove very broken example.
This could never be a full rustdoc test, since rustdoc never
runs tests for private items.   Even if it were a rustdoc test,
it uses a bunch of types that aren't exposed in the right places,
and it invokes nonexistent functions, and it assumes a `self`
that isn't there.

In lieu of writing a new untested test, I've added a note to refer
the developer to where they can find working example code.

Nick Mathewson 1691c35392 circmgr: Use a slightly nicer way to pick a circuit from our pool.
This algorithm only looks at circuits until it finds one that
satisfies our needs.  To get a random circuit, it just randomizes
the starting point within the pool.

This optimization may help if we let circuit pools grow large.
2023-06-16 12:14:49 -04:00
Nick Mathewson 686d5cf209 circmgr: Make hspool size dynamic
Previously we'd always try to keep 8 circuits ready.  That doesn't
make sense if we are super-busy.  Instead, if we run out of
circuits, we double the amount that we try to keep ready, and if we
never go under 80% of our target number, we half the number we try
to keep ready.

We limit the rate of change here, to make sure that we aren't
flapping too much or shrinking too aggressively.

This algorithm is still a mite arbitrary, and will need tuning in
the future.
2023-06-16 12:11:49 -04:00
Nick Mathewson 69179c5dfe circmgr::hspool: Move the Mutex into an intermediary Inner struct
This will be helpful as we complexify the pool behavior a bit.
