* Remove custom source implementation for ErrorRobin Krahl2020-08-30
| | | | | | | | | | | | | This patch removes the custom implementation of the source method of the std::error::Error trait for the error::Error type. This means that the default implementation is used that always returns None. The reason for this change is that we already print the error message of the source error in the Display implementation. This leads to a duplicated error message if both Display and source are checked, for example with anyhow’s error formatting. See this thread for more information: https://lists.sr.ht/~ireas/nitrokey-rs-dev/%3C6e0b4dc8-9059-a113-e98e-b49e52818c75%40posteo.net%3E

|\
| * Release v0.7.0v0.7.0Robin Krahl2020-07-14
|/ | | | | This release changes the Error enum to implement Send, Sync and 'static for compatibility with error handling crates like anyhow.
* Merge branch 'poison-error' into nextRobin Krahl2020-07-14
|\ | | | | | | | | | | | | This patch series refactors the Error enum and ensures that it is Send, Sync and 'static. This makes sure that it is compatible with the anyhow crate. To achieve this, we drop the RandError variant and remove the sync::PoisonError value from the PoisonError variant.
| * Ensure Error trait implementationsRobin Krahl2020-07-08
| | | | | | | | | | | | The anyhow crate requires that error types are error::Error, Send, Sync and 'static. This patch implements a simple static assertion that our Error type implements these traits.
| * Remove Error::RandError variantRobin Krahl2020-07-08
| | | | | | | | | | | | | | | | | | | | Since we update rand_os to version 0.2 in commit 6c138eaa850c745b97b7e48a201db0cbaad8e1e0, the random number generation can no longer fail. Therefore the Error::RandError variant is no longer needed. As we did not want to break the public API, we still kept the RandError variant. This patch removes the RandError variant for good.
| * Remove sync::PoisonError from Error::PoisonErrorRobin Krahl2020-07-08
|/ | | | | | | | | | | | | | | | | | Previously, the Error::PoisonError contained the sync::PoisonError that caused the error. This is problematic as sync::PoisonError does not implement Send, making it impossible to use the Error enum with the anyhow crate. At the same time, storing the sync::PoisonError is not very useful. If a user wants to access the poisoned lock, they can call the force_take function. Therefore we remove the sync::PoisonError value from the Error:: PoisonError variant. This also allows us to simplify the From<sync::PoisonError<…>> and From<sync::TryLockError<…>> implementations as we no longer need to know the type of the mutex that caused the error. For more information, see this thread: https://lists.sr.ht/~ireas/nitrokey-rs-dev/%3C68ed0f3f-d98f-63bc-04d2-81b6d6cde560%40posteo.net%3E
* Use find(…) instead of skip_while(…).next()Robin Krahl2020-07-08
| | | | | This patch replaces calls to skip_while(…).next() for an iter::Iterator with a call to find(…), as suggested by clippy.

|\
| * Release v0.6.0v0.6.0Robin Krahl2020-02-03
|/ | | | | | This release introduces a new struct SerialNumber that represents the serial number of a Nitrokey device, replacing the strings we used previously.
* Refactor string handling in utilRobin Krahl2020-02-03
| | | | | | | | | | | | | The util module provides helper methods to deal with the C strings returned by libnitrokey. The current implementation has to problems: - It causes unnecessary allocations if we only want to look at the string, for example in get_serial_number. - If the conversion from a CStr to a String fails, the string pointer is not freed. Therefore this patch introduces the run_with_str function that executes a function with the string returned by libnitrokey and then makes sure that the pointer is freed correctly.
* Represent serial numbers using SerialNumber structRobin Krahl2020-02-03
| | | | | | | | | | | | | | | | | In a previous commit, we changed the serial number representation from a string to an integer. This made it easier to compare serial numbers, but also introduced new problems: - Serial numbers should be formatted consistently, for example as "{:#010x}". It is hard to ensure this for an integer value. - The format of the serial number may be subject to change. Users should not rely too much on the u32 representation. Therefore we introduce a new SerialNumber struct that represents a serial number. Currently it only stores a u32 value. The following traits and functions can be used to access its value: - FromStr for string parsing - ToString/Display for string formatting - as_u32 to access the underlying integer value
* Merge branch 'get_config' into nextRobin Krahl2020-02-03
|\ | | | | | | | | | | | | This patch series changes the Device::get_config implementation to use libnitrokey’s NK_get_status instead of NK_read_config. This does results in the same command being sent to the Nitrokey device, but avoids a new[]/free mismatch and makes the parsing more robust.
| * Use NK_get_status to implement Device::get_configRobin Krahl2020-02-03
| | | | | | | | | | | | | | | | | | | | | | | | libnitrokey’s NK_read_config function returns a pointer to an array that has been allocated using new[]. We would have to delete this pointer using delete[], but we only have access to free. Therefore this patch modifies the Device::get_config function to call NK_get_status instead of NK_read_config. This also makes the code more safe as we get the data as a struct instead of an array. It does not add much overhead as NK_read_config also executes the GET_STATUS command on the Nitrokey device.
| * Implement From<&NK_status> for RawConfigRobin Krahl2020-02-03
|/ | | | | | This makes it easier to parse only the config part of the NK_status struct and avoids code duplication in the upcoming get_config refactoring.
* Merge branch 'hotfix-0.5.2' into nextRobin Krahl2020-01-28
|\
| * Release v0.5.2v0.5.2Robin Krahl2020-01-28
| | | | | | | | | | This patch release makes the handling of the randomly generated temporary passwords more robust.
| * Regenerate temporary passwords with null bytesRobin Krahl2020-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we silently cut off temporary passwords that contained a null byte. With the change to CString, we returned a LibraryError instead. With this patch, we change to generate_password function to continue generating passwords until we have a password without a null byte. The chance of generating a password with a null byte is ca. 10 % for our temporary password with 25 characters. Therefore the chance of having to re-generate the password multiple times is low enough that we don’t bother with re-generating only the null bytes of the password for the time being. This should be improved in the future.
| * Remove AuthenticatedDevice::temp_password_ptrRobin Krahl2020-01-28
| | | | | | | | | | | | | | | | We introduced the AuthenticatedDevice::temp_password_ptr function to reduce the number of casts needed in our code base. Since we switched from Vec<u8> to CString, we no longer have to cast the return value of as_ptr. Therefore we can remove the temp_password_ptr function to reduce code complexity.
| * Use CString to store temporary passwordsRobin Krahl2020-01-28
| | | | | | | | | | | | | | This patch changes the generate_password function and the User and Admin structs to use a CString instead of a Vec<u8> when storing temporary passwords. This makes sure that the strings that are passed to the C API are properly null-terminated.

* | | | | | Always store serial numbers as integersRobin Krahl2020-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consistently uses u32 integers to store and return the serial number of a Nitrokey device. This makes it easier to convert and compare the serial number, as it is a unique representation and as formatting an integer cannot fail.

* | | | | | Add String value to the Error::UnexpectedError variantRobin Krahl2020-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To make debugging of unexpected errors easier, this patch adds an associated String value with a description of the unexpected behavior to the UnexpectedError variant of the Error enum.

* | | | | Fix serial number for older Nitrokey Pro in list_devicesRobin Krahl2020-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we assumed that the serial number returned by hidapi contains the Nitrokey serial number as the least significant bytes. As disussed here [0], this is not true for Nitrokey Pro devices with firmware version 0.8 or older: They write the serial number to the most significant bytes instead. This patch update the get_hidapi_serial_number function so that list_devices now returns the correctly formatted and truncated serial number for all Nitrokey Pro devices. It also makes sure that the serial number is lowercase to be consistent with libnitrokey’s formatting.

For the Nitrokey Storage: - Getting the SD card usage (Storage::get_sd_card_usage). - Getting the status of a background operation (Storage::get_operation_status). - Filling the SD card with random data (Storage::fill_sd_card). With this release, we support all functions provided by libnitrokey – except those listed as unsupported in the readme file. Therefore we should be able to release a stable version 1.0.0 soon.

* | | | Remove multiple PWS item from todo listRobin Krahl2020-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit f49e61589e32217f97c94aa86d826f6b65170fba, we changed the GetPasswordSafe::get_password_safe to take a mutable reference to a device. This makes sure that we cannot have two PWS instances for one device at the same time, so we can drop the corresponding item from the todo list.
* | | | Add basic usage examplesRobin Krahl2020-01-14
| | | | | | | | | | | | | | | | | | | | This patch adds two basic usage examples: listing and connecting to Nitrokey devices, and generating a one-time password.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for libnitrokey’s NK_fill_SD_card_with_random_data function. It is executed by the fill_sd_card function of the Storage struct. We also add a new test case that is set to ignore because it takes between 30 and 60 minutes to run.
* | | | Add the get_operation_status function to the Storage structRobin Krahl2020-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the NK_get_progress_bar_value function: It adds the OperationStatus enum that stores the return value of this command and adds the get_operation_status function to the Storage struct that executes the command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes two items from the todo list: - Check timing in Storage tests: Since we introduced the two seconds timeout, no test failed due to timing issues. There is nothing we can do to check it more precisely, so we just have to live with it for now. - Consider restructuring `device::StorageStatus`: We already have structs for the volume status and firmware version. There is no need to extract more fields.
* | | | Add the get_sd_card_usage function to the Storage structRobin Krahl2020-01-14
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the NK_get_SD_usage_data function. It returns a range of the SD card that has not been accessed during this power cycle.
* | | | Rename Status::get_status to get_storage_statusRobin Krahl2020-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the last patch, we added the get_status function to the Device trait. This patch renames the Storage::get_status function to get_storage_status to resolve the name clash – though allowed by the compiler, it is rather confusing for the end user.
* | | | Add support for the GET_STATUS commandRobin Krahl2020-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the GET_STATUS command that returns the status information common to all Nitrokey devices. It can be accessed using the Device::get_status function and is stored in a Status struct. Due to a bug in the Storage firmware [0], the GET_STATUS command returns wrong firmware versions and serial numbers. Until this is fixed in libnitrokey [1], we have to manually execute the GET_DEVICE_STATUS command to fix these values for the Nitrokey Storage. Also, this leads to a name clash with the existing Storage::get_status function, which will be renamed in an upcoming patch.
