From 9428ce3221209828b8cff0e34957ebb9b10b2d99 Mon Sep 17 00:00:00 2001 From: Robin Krahl Date: Mon, 21 May 2018 21:59:25 +0000 Subject: Correct invalid slot handling While the Nitrokey device would generate a WrongSlot error, libnitrokey catches these errors and raises an InvalidSlotException with error code 201. This patch matches this error code to CommandError::InvalidSlot, corrects the documentation and adds test cases. To be able to test a failing OTP generation command, we have to adapt get_string_result to free the string only if successful. This is due to the segfault issue in libnitrokey v3.3 (see todo list). --- src/lib.rs | 28 +++++++++++++++------------- src/tests/pro.rs | 34 ++++++++++++++++++++++++++++++++-- 2 files changed, 47 insertions(+), 15 deletions(-) (limited to 'src') diff --git a/src/lib.rs b/src/lib.rs index 471d481..117659f 100644 --- a/src/lib.rs +++ b/src/lib.rs @@ -394,8 +394,8 @@ pub trait Device { /// /// # Errors /// + /// - [`InvalidSlot`][] if there is no slot with the given number /// - [`SlotNotProgrammed`][] if the given slot is not configured - /// - [`WrongSlot`][] if there is no slot with the given number /// /// # Example /// @@ -413,8 +413,8 @@ pub trait Device { /// # } /// ``` /// + /// [`InvalidSlot`]: enum.CommandError.html#variant.InvalidSlot /// [`SlotNotProgrammed`]: enum.CommandError.html#variant.SlotNotProgrammed - /// [`WrongSlot`]: enum.CommandError.html#variant.WrongSlot fn get_hotp_slot_name(&self, slot: u8) -> Result { unsafe { result_from_string(nitrokey_sys::NK_get_hotp_slot_name(slot)) } } @@ -423,8 +423,8 @@ pub trait Device { /// /// # Errors /// + /// - [`InvalidSlot`][] if there is no slot with the given number /// - [`SlotNotProgrammed`][] if the given slot is not configured - /// - [`WrongSlot`][] if there is no slot with the given number /// /// # Example /// @@ -442,8 +442,8 @@ pub trait Device { /// # } /// ``` /// + /// [`InvalidSlot`]: enum.CommandError.html#variant.InvalidSlot /// [`SlotNotProgrammed`]: enum.CommandError.html#variant.SlotNotProgrammed - /// [`WrongSlot`]: enum.CommandError.html#variant.WrongSlot fn get_totp_slot_name(&self, slot: u8) -> Result { unsafe { result_from_string(nitrokey_sys::NK_get_totp_slot_name(slot)) } } @@ -569,9 +569,9 @@ pub trait Device { /// /// # Errors /// + /// - [`InvalidSlot`][] if there is no slot with the given number /// - [`NotAuthorized`][] if OTP generation requires user authentication /// - [`SlotNotProgrammed`][] if the given slot is not configured - /// - [`WrongSlot`][] if there is no slot with the given number /// /// # Example /// @@ -588,9 +588,9 @@ pub trait Device { /// ``` /// /// [`get_config`]: #method.get_config + /// [`InvalidSlot`]: enum.CommandError.html#variant.InvalidSlot /// [`NotAuthorized`]: enum.CommandError.html#variant.NotAuthorized /// [`SlotNotProgrammed`]: enum.CommandError.html#variant.SlotNotProgrammed - /// [`WrongSlot`]: enum.CommandError.html#variant.WrongSlot fn get_hotp_code(&self, slot: u8) -> Result { unsafe { return result_from_string(nitrokey_sys::NK_get_hotp_code(slot));
