* Introduce into_manager for DeviceRobin Krahl2019-07-09
| | | | | | | | To enable applications like nitrokey-test to go back to a manager instance from a Device instance, we add the into_manager function to the Device trait. To do that, we have to keep track of the Manager’s lifetime by adding a lifetime to Device (and then to some other traits that use Device).
* Store mutable reference to Manager in DeviceRobin Krahl2019-07-08
| | | | | | | | | | | | | In the last patches, we ensured that devices can only be obtained using the Manager struct. But we did not ensure that there is only one device at a time. This patch adds a mutable reference to the Manager instance to the Device implementations. The borrow checker makes sure that there is only one mutable reference at a time. In this patch, we have to remove the old connect, Pro::connect and Storage::connect functions as they do no longer compile. (They discard the MutexGuard which invalidates the reference to the Manager.) Therefore the tests do no longer compile.
* Move {Pro, Storage}::connect into ManagerRobin Krahl2019-07-08
| | | | | | | As part of the connection refactoring, this patch moves the connect methods of the Pro and Storage structs into the Manager struct. To maintain compatibility with nitrokey-test, the old methods are not removed but marked as deprecated.
* Move the connect_model function into ManagerRobin Krahl2019-07-08
| | | | | | As part of the connection refactoring, this patch moves the connect_model function to the Manager struct. As the connect_model function is not used by nitrokey-test, it is removed.
* Move the connect function into ManagerRobin Krahl2019-07-08
| | | | | | | As part of the connection refactoring, we replace the connect function with the Manager::connect method. To maintain compatibility with nitrokey-test, the connect function is not removed but marked as deprecated.
* Add Manager struct to manage Nitrokey connectionsRobin Krahl2019-07-08
| | | | | | | | | | | | | As part of the connection refactoring, we introduce the Manager struct that deals with connection management. To make sure there can be only once instance of the manager, we add a global static Mutex that holds the single Manager instance. We use the struct to ensure that the user can only connect to one device at a time. This also changes the Error::PoisonError variant to store the sync::PoisonError. This allows the user to call into_inner on the PoisonError to retrieve the MutexGuard and to ignore the error (for example useful during testing).
* Add ConcurrentAccessError and PoisonError variantsRobin Krahl2019-07-08
| | | | | | | | | This patch prepares the refactoring of the connection methods by introducing the Error variants ConcurrentAccessError and PoisonError. ConcurrentAccessError indicates that the user tried to connect to obtain a token that is currently locked, and PoisonError indicates that a lock has been poisoned, i. e. a thread panicked while accessing using a token.
* Update list of new and unsupported functionsRobin Krahl2019-07-08
| | | | | | | | | | | | | | | This patch updates the list of unsupported functions in the README and the TODO and the list of functions changed in the libnitrokey 3.5 release: - List all `*_as_string` functions as unsupported. - List deprecated functions as unsupported. - List `NK_read_HOTP_slot` as unsupported until an equivalent function for TOTP exists. - Ignore the changes to `NK_get_progress_bar_value` as the function is not yet used by `nitrokey-rs`. - Add the new functions from version 3.5 to the list of missing functions.

* Update nitrokey-test and add nitrokey-test-stateRobin Krahl2019-07-07
| | | | | | | | | The new 0.2.1 version of nitrokey-test requires an additional crate, nitrokey-test-state. This patch updates the nitrokey-test version and adds the nitrokey-test-state dependency in version 0.1.0. See this thread [0] for more information.

* Update nitrokey-sys to version 3.5Robin Krahl2019-07-05
| | | | | | | | | As the return type of the NK_get_{major,minor}_firmware_version methods changed with libnitrokey 3.5, we also have to adapt our get_firmware_version function in device.rs. This patch also updates the changelog and the todo list with the changes caused by the new libnitrokey version.
* Fix cargo dependency version specificationsRobin Krahl2019-07-06
| | | | | | | | | | Firstly, the libnitrokey API contains breaking changes between minor versions. Therefore we have to fix the nitrokey-sys version using a tilde requirement ("~3.4" means ">= 3.4.0, < 3.5.0"). Secondly, nitrokey-test’s 0.2.1 release requires some changes that are not yet implemented in this crate, so we have to pin its version to 0.2.0.
* Merge branch 'revert' into nextRobin Krahl2019-07-06
|\ | | | | | | | | | | | | | | | | | | | | | | The tests with the 0.4.0-alpha.1 version showed that the approach using mutable references to the Device in User, Admin and PasswordSafe causes problems in nitrocli, see [0]. Therefore, these changes are reverted.

* Remove PIN constants from testsRobin Krahl2019-02-04
| | | | | | In a previous commit, we introduced the DEFAULT_{ADMIN,USER}_PIN constants. Therefore we no longer need in the {ADMIN,USER}_PASSWORD constants in the util module for the tests.

| * Store mutable reference to Device in PasswordSafeRobin Krahl2019-02-02
| | | | | | | | | | | | | | | | | | The current implementation of PasswordSafe stored a normal reference to the Device. This patch changes the PasswordSafe struct to use a mutable reference instead. This allows the borrow checker to make sure that there is only one PasswordSafe instance at a time. While this is currently not needed, it will become important once we can lock the PWS on the Nitrokey when dropping the PasswordSafe instance.
| * Refactor User and Admin to use a mutable referenceRobin Krahl2019-02-02
| | | | | | | | | | | | | | | | | | | | | | | | In the initial nitrokey-rs implementation, the Admin and the User struct take the Device by value to make sure that the user cannot initiate a second authentication while this first is still active (which would invalidate the temporary password). Now we realized that this is not necessary – taking a mutable reference has the same effect, but leads to a much cleaner API. This patch refactors the Admin and User structs – and all dependent code – to use a mutable reference instead of a Device value.
| * Require mutable reference if method changes device stateRobin Krahl2019-02-02
| | | | | | | | | | | | | | | | | | | | | | | | Previously, all methods that access a Nitrokey device took a reference to the device as input. This method changes methods that change the device state to require a mutable reference instead. In most case, this is straightforward as the method writes data to the device (for example write_config or change_user_pin). But there are two edge cases: - Authenticating with a PIN changes the device state as it may decrease the PIN retry counter if the authentication fails. - Generating an HOTP code changes the device state as it increases the HOTP counter.
| * Add device_mut method to DeviceWrapperRobin Krahl2019-02-02
| | | | | | | | | | | | To prepare the mutability refactoring, we add a device_mut method to DeviceWrapper that can be used to obtain a mutable reference to the wrapped device.
| * Implement DerefMut for User and AdminRobin Krahl2019-02-02
|/ | | | | | As we want to change some methods to take a mutable reference to a Device, we implement DerefMut for User<T> and Admin<T> so that users can obtain a mutable reference to the wrapped device.
* Add set_encrypted_volume_mode method to StorageRobin Krahl2019-01-31
| | | | | | | | | | Previously, we considered this command as unsupported as it only was available with firmware version 0.49. But as discussed in nitrocli issue 80 [0], it will probably be re-enabled in future firmware versions. Therefore this patch adds the set_encrypted_volume_mode to Storage.

* Add assert_any_ok macro to unit testsRobin Krahl2019-01-28
| | | | | | | | Sometimes we cannot use assert_ok! as we can’t compare the Ok value (or do not want to). For these cases, this patch adds the new assert_any_ok macro to use instead of assert!(x.is_ok()). The advantage is that the error information is not discarded but printed in a helpful error message.
* Add unwrap_ok macro to replace unwrap in unit testsRobin Krahl2019-01-28
| | | | | | The unwrap error message is not very useful. This patch adds the unwrap_ok macro that is basically the same as unwrap but prints a more readable error message.
* Accept UTF-8 errors in password safe testsRobin Krahl2019-01-28
| | | | | | | After a factory reset or after building the AES key, the password safe contains garbage data. This will most likely not be valid UTF-8. Therefore we change the tests to also accept an UTF-8 error in these cases.
* Add get_firmware_version methodRobin Krahl2019-01-28
| | | | | | | | This patch combines the get_{major,minor}_firmware_version methods into the new get_firmware_version method that returns a FirmwareVersion struct. Currently, this requires casting from i32 to u8. But this will be fixed with the next libnitrokey version as we change the return types for the firmware getters.
* Always return a Result when communicating with a deviceRobin Krahl2019-01-27
| | | | | | | | Previously, we sometimes returned a value without wrapping it in a result if the API method did not indicate errors in the return value. But we can detect errors using the NK_get_last_command_status function. This patch changes the return types of these methods to Result<_, Error> and adds error checks.

* Replace or with or_else in get_cstringRobin Krahl2019-01-27
| | | | | To avoid unnecessary function calls, we replace the or with an or_else in get_cstring.
* Remove the static lifetime modifier from constantsRobin Krahl2019-01-27
| | | | | The DEFAULT_{ADMIN,USER}_PIN constants implicitly have static lifetime. Therefore we can remove the static lifetime modifiers.
* Rename Error::Unknown to Error::UnknownErrorRobin Krahl2019-01-27
| | | | | For consistency with the other Error variants, we rename Unknown to UnknownError.
* Remove the Result typedefRobin Krahl2019-01-27
| | | | | | | | | Many of our functions do not return a Result<_, Error>, but for example a Result<_, (Device, Error)>. We only use the typedef in one function, but it makes the other functions more complicated as we have to use result::Result (if crate::Result is imported). Therefore, this patch removes the typedef. Applications or libraries can still redefine it if they want to.
* Remove triggers from build scriptsRobin Krahl2019-01-25
| | | | | | I changed the build setup so that the trigger is determined by the branch being pushed to. Therefore the triggers in the build scripts are no longer needed and removed in this patch.
* Add tolerance for timing issues to the TOTP testsRobin Krahl2019-01-25
| | | | | | The TOTP test with the timestamp 59 often fails as the Nitrokey’s clock ticks between setting the time and generating the TOTP code. This patch also allows the TOTP code for timestamp 60 for this test case.
* Remove rand_core::Error from public APIRobin Krahl2019-01-25
| | | | | | | rand_core does not have a stable release yet, and it is unlikely that there will be one soon. To be able to stabilize nitrokey without waiting for a stable rand_core version, we remove the rand_core::Error type from the public API and replace it with a Box<dyn error::Error>.
* Add reuse linter to the lint buildRobin Krahl2019-01-23
| | | | | The reuse linter verifies that nitrokey-rs complies with the REUSE specification 2.0.
* Move format checks into lint buildRobin Krahl2019-01-23
| | | | | | While we want to test the code on multiple platforms and with different configurations, it is sufficient to execute the linting once. Therefore we move the formatting checks into a new lint build.
* Add license and copyright informationRobin Krahl2019-01-23
| | | | | | | This patch adds license and copyright information to all files to make nitrokey-rs compliant with the REUSE practices [0]. [0] https://reuse.software/practices/2.0/

* Implement From<(T: Device, Error)> for ErrorRobin Krahl2019-01-23
| | | | | | Not all users of the authenticate methods want to use the device after an error, so implementing From<(T: Device, Error)> for Error makes it easier for them to discard the device.
* Return UTF-8 error if libnitrokey returns an invalid stringRobin Krahl2019-01-23
| | | | | | | Previously, we used lossy UTF-8 conversion. Yet the user should be notified if we have a problem instead of silently changing the data. Therefore, we now return an error if we enocunter an invalid UTF-8 string. This leads to a change in `get_library_version`’s signature.
* Add Error::Utf8Error variantRobin Krahl2019-01-23
| | | | | Previously, we just ignored UTF-8 errors. This patch prepares the Utf8Error variant so that we are able to return UTF-8 errors.
