This commit adds quite a bit of documentation about the current status
of the project, including links to GitHub issues for the different Rust
modules which map to specific pieces of functionality.
The intent is to track the current status of the project in the
README.md as that's more up-to-date than the docs.rs documentation
(which depends on a crate release to get updated).
Adds an extremely basic initial test to ensure that we are able to
connect to a YubiKey.
The test is marked `#[ignore]` in the hope that we can eventually start
adding tests which run in CI, e.g. against a mock card.
This also includes a fix for calculating the APDU size, since the ones
we were sending originally were overly long.
Callers of this function always pad up to `CB_PIN_MAX` with `0xFF`.
The logic being changed here was previously identical to the `_verify`
function in `ykpiv.c`:
https://github.com/Yubico/yubico-piv-tool/blob/8ba243f/lib/ykpiv.c#L1299
...but @str4d noticed this potentially allows a caller to send an
unpadded PIN, which may (or may not) be an issue.
It seems like given we're inside a while loop which also has this
conditional, the original code should've been fine, but this change
makes it closer to the original C code.
This commit contains a "big bang" refactor/rewrite which does the
following:
- Replaces all `SCard*` FFI calls with the `pcsc` crate, which provides
a safe, portable PC/SC API across Windows, macOS, and Linux
- Refactors the `util` module into modules representing the various
device functions and concepts, e.g. `certificate`, `key`, `mgm`
- Replaces all usage of `libc` with `std` functionality, and in many
places rewriting functionality to use safe code.
- Removes `ykpiv_` from all function names, and `Piv*` from type names.
In 20/20 hindsight I wish I had done this commit more incrementally so
as to make it easier to review. Que sera sera.
However, realistically we need to test all functionality on the device
to ensure that it actually works. Going forward I would like to put
pretty much all of the current code behind an `untested` cargo feature,
and then remove it for each bit of functionality we test.
Changes the `APDU` struct into a builder for serialized APDU messages.
This makes APDU construction safer and more idiomatic, and also caught a
few bugs in the process (missing templ from the C translation).
There was originally another `Error` type from the translation. Now that
it's gone, and we don't presently have a type just named `Error`, this
renames the current `ErrorKind` type now that the original was deleted.
Switches all of the previous `state->verbose`-gated `eprintln!` calls to
use macros from the `log` crate, trying to map them onto the previous
verbosity levels, more or less following this mapping:
0. off
1. error/info/warn (depending on context)
2. trace
This additionally includes a bunch of logic/branch reformatting (and
occasional missed constants), since getting rid of all the gating on
verbose provided ample opportunities to clean up the code. Hopefully I
didn't break too much in the process!
This repository contains the entire history of the C source code since
the project started.
However, the code is largely translated at this point, so keeping the C
code around at this point no longer makes sense. If we need to consult
it or the history of changes, git has them.
This commit gets the Rust code to compile! 🎉
Additionally, it fixes all of the commented out code that was failing
translation from C due to the use of unions, namely around the APDU
messages.
It does a fair amount of reformatting around branches, with the net
result hopefully being something actually a bit closer to the C code,
and a straightforward list of `if` statements.
It also removes all of the remaining externs that aren't supposed to be
externs, replacing them with a more straightforward usage of the module
system.
Finally it fixes all errors and warnings (relating to e.g. usage of
uninitialized memory), in addition to most clippy lints! (some have
been explicitly disabled)
All that said, it still doesn't do anything: it needs to be wired up to
a PCSC library first before that will be possible. But hey, it compiles!
This commit contains a multitude of fixes and some initial translation
work so the first rustc pass compiles.
It removes `unsafe extern "C"` declarations, so now there are a number
of errors about invocations of unsafe functions that need to be
addressed. They should each be scoped to an `unsafe` block so as to aid
in an eventual safe translation.
Some of the functions are now using the module system rather than
`extern "C"` bindings, but the translation is not complete.
This either fixes or adds "FIXME" notes for any parts of the code that
corrode had trouble translating.
Namely there are a number of places members of the APDU struct(?) were
accessed which corrode failed to translate.
- Adds initial `Cargo.toml` (and `Cargo.lock` to `.gitignore`)
- Deletes `tool` (it seems hard to `corrode`)
- Moves `lib/tests` => `tests` (we should figure out how to translate them)
- Moves `lib` => `src` to match Rust conventions
- Renames `lib/ykpiv.rs` => `src/lib.rs` to match Rust conventions
- Adds copyright from `ykpiv.h` to the top of all `*.rs` files
