-# Changelog
-All notable changes to this project will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [Unreleased]
-
-## [1.1.0] - 2019-02-17
-### Added
- Code cleanup
- Buffer over-read bug fix
- U2F counter endianness bug fix
- More testing
- Extension interface to U2F and FIDO2
-    - Read firmware version
-    - Read RNG bytes
-
-## [1.1.1] - 2019-03-01
-
- This version fixes an incorrect error code returned in U2F.  
-
-## [2.0.0] - 2019-03-01
-
- Merge of NFC functionality branch
- Bug fix with compiled USB name being too long causing buffer overrun
- Change upper byte of counter from `0xff` to `0x7f` to fix issues with some websites.
-
-## [2.1.0] - 2019-03-31
-
-WARNING: This update may break previous registrations! This is because we fixed the U2F counter for good (rather than arbitrarily set the upper byte high for backwards-compatibility reasons, which ends up causing other issues).
-
- Adds hmac-secret extension support. This extension is used for generating 32 or 64 byte symmetric keys using parameters from the platform and secrets on the authenticator. It's used by Windows Hello - - for offline authentication.
- Fix bug in FIDO auth, where setting the pin requires all previous registrations to use pin. Only UV bit needs to be cleared.
- Slightly change serial emulation USB descriptor to make it less abused by Linux Modem Manager.
-
-## [2.2.0] - 2019-04-17
-
- Fixes the ordering of keys encoded in CBOR maps to be canonical ordering. They previously were not ordered in any particular way and caused issues for Chrome. #170
- Fixes CTAP2 implementation to accept credential IDs created by the CTAP1 implementation. So registering with U2F and later authenticating with FIDO2 should work.

 Solo is an upgrade to [U2F Zero](https://github.com/conorpp/u2f-zero). It was born from Conor's passion for making secure hardware, and from our shared belief that security should be open to be trustworthy, in hardware like in software.

-Contributors are welcome. The ultimate goal is to have a FIDO2 security key supporting USB, NFC, and BLE interfaces, that can run on a variety of MCUs.

+# Building solo
+
 To build, develop and debug the firmware for the STM32L432.  This will work
 for Solo Hacker, the Nucleo development board, or your own homemade Solo.

 There exists a development board [NUCLEO-L432KC](https://www.st.com/en/evaluation-tools/nucleo-l432kc.html) you can use;  The board does contain a debugger, so all you need is a USB cable (and some [udev](/udev) [rules](https://rust-embedded.github.io/book/intro/install/linux.html#udev-rules)).

-# Prerequisites
+## Prerequisites

 Install the [latest ARM compiler toolchain](https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads) for your system.  We recommend getting the latest compilers from ARM.

 You can also install the ARM toolchain  using a package manager like `apt-get` or `pacman`,
 but be warned they might be out of date.  Typically it will be called `gcc-arm-none-eabi binutils-arm-none-eabi`.

+Install `solo-python` usually with `pip3 install solo-python`. The `solo` python application may also be used for [programming](#programming).

+# Nucleo32 board preparation
+
+Additional steps are required to run the firmware on the Nucleo32 board.
+
+## USB-A cable
+
+Board does not provide an USB cable / socket for the target MCU communication.
+Own provided USB plug has to be connected in the following way:
+
+| PIN / Arduino PIN | MCU leg | USB wire color | Signal |
+| ----------------- | ------- | -------------- | ------ |
+| D10 / PA11        | 21      | white          | D-     |
+| D2 / PA12         | 22      | green          | D+     |
+| GND (near D2)     | ------- | black          | GND    |
+| **not connected** | ------- | red            | 5V     |
+
+Each USB plug pin should be connected via the wire in a color defined by the standard. It might be confirmed with a
+multimeter for additional safety. USB plug description:
+
+| PIN | USB wire color | Signal |
+| --- | -------------- | ------ |
+| 4   | black          | GND    |
+| 3   | green          | D+     |
+| 2   | white          | D-     |
+| 1   | red            | 5V     |
+
+See this [USB plug] image, and Wikipedia's [USB plug description].
+
+Plug in [USB-A_schematic.pdf] has wrong wire order, registered as [solo-hw#1].
+
+The power is taken from the debugger / board (unless the board is configured in another way).
+Make sure 5V is not connected, and is covered from contacting with the board elements.
+
+Based on [USB-A_schematic.pdf].
+
+## Firmware modification
+
+Following patch has to be applied to skip the user presence confirmation, for tests. Might be applied at a later stage.
+
+```text
+diff --git a/targets/stm32l432/src/app.h b/targets/stm32l432/src/app.h

+
+## Development environment setup
+
+Environment: Fedora 29 x64, Linux 4.19.9
+
+See <https://docs.solokeys.io/solo/building/> for the original guide. Here details not included there will be covered.
+
+### Install ARM tools Linux
+
+1.  Download current [ARM tools] package: [gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2].
+
+2.  Extract the archive.
+
+3.  Add full path to the `./bin` directory as first entry to the `$PATH` variable,
+    as in `~/gcc-arm/gcc-arm-none-eabi-8-2018-q4-major/bin/:$PATH`.
+
+### Install ARM tools OsX using brew package manager
+
+```bash
+brew tap ArmMbed/homebrew-formulae
+brew install arm-none-eabi-gcc
+```
+
+### Install flashing software
+
+ST provides a CLI flashing tool - `STM32_Programmer_CLI`. It can be downloaded directly from the vendor's site:
+1\. Go to [download site URL](https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stm32cubeprog.html),
+go to bottom page and from STM32CubeProg row select Download button.
+2\. Unzip contents of the archive.
+3\. Run \*Linux setup
+4\. In installation directory go to ./bin - there the ./STM32_Programmer_CLI is located
+5\. Add symlink to the STM32 CLI binary to .local/bin. Make sure the latter it is in $PATH.
+
+If you're on OsX and installed the STM32CubeProg, you need to add the following to your path:
+
+```bash
+# ~/.bash_profile
+export PATH="/Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/MacOs/bin/":$PATH
+```
+
+## Building and flashing
+
+### Building
+
+Please follow <https://docs.solokeys.io/solo/building/>, as the build way changes rapidly.
+Currently (8.1.19) to build the firmware, following lines should be executed
+
+```bash
+# while in the main project directory
+cd targets/stm32l432
+make cbor
+make build-hacker DEBUG=1
+```
+
+Note: `DEBUG=2` stops the device initialization, until a serial client will be attached to its virtual port.
+Do not use it, if you do not plan to do so.
+
+### Flashing via the Makefile command
+
+```bash
+# while in the main project directory
+# create Python virtual environment with required packages, and activate
+make venv
+. venv/bin/activate
+# Run flashing
+cd ./targets/stm32l432
+make flash
+ # which runs:
+ # flash: solo.hex bootloader.hex
+ #	python merge_hex.py solo.hex bootloader.hex all.hex (intelhex library required)
+ #	STM32_Programmer_CLI -c port=SWD -halt -e all --readunprotect
+ #	STM32_Programmer_CLI -c port=SWD -halt  -d all.hex -rst
+```
+
+### Manual flashing
+
+In case you already have a firmware to flash (named `all.hex`), please run the following:
+
+```bash
+STM32_Programmer_CLI -c port=SWD -halt -e all --readunprotect
+STM32_Programmer_CLI -c port=SWD -halt  -d all.hex -rst
+```
+
+## Testing
+
+### Internal
+
+Project-provided tests.
+
+#### Simulated device
+
+A simulated device is provided to test the HID layer.
+
+##### Build
+
+```bash
+make clean
+cd tinycbor
+make
+cd ..
+make env2
+```
+
+##### Execution
+
+```bash
+# run simulated device (will create a network UDP server)
+./main
+# run test 1
+./env2/bin/python tools/ctap_test.py
+# run test 2 (or other files in the examples directory)
+./env2/bin/python python-fido2/examples/credential.py
+```
+
+#### Real device
+
+```bash
+# while in the main project directory
+# not passing as of 8.1.19, due to test solution issues
+make fido2-test
+```
+
+### External
+
+#### FIDO2 test sites
+
+1.  <https://www.passwordless.dev/overview>
+2.  <https://webauthn.bin.coffee/>
+3.  <https://webauthn.org/>
+
+#### U2F test sites
+
+1.  <https://u2f.bin.coffee/>
+2.  <https://demo.yubico.com/u2f>
+
+#### FIDO2 standalone clients
+

+4.  <https://github.com/google/pyu2f>
+
+## USB serial console reading
+
+Device opens an USB-emulated serial port to output its messages. While Nucleo board offers such already,
+the Solo device provides its own.
+
+-   Provided Python tool
+
+```bash
+python3 ../../tools/solotool.py monitor /dev/solokey-serial
+```
+
+-   External application
+
+```bash
+sudo picocom -b 115200 /dev/solokey-serial
+```
+
+where `/dev/solokey-serial` is an udev symlink to `/dev/ttyACM1`.
+
+## Other
+
+### Dumping firmware
+
+Size is calculated using bash arithmetic.
+
+```bash
+STM32_Programmer_CLI -c port=SWD -halt  -u 0x0 $((256*1024)) current.hex
+```
+
+### Software reset
+
+```bash
+STM32_Programmer_CLI -c port=SWD  -rst
+```
+
+### Installing required Python packages
+
+Client script requires some Python packages, which could be easily installed locally to the project
+via the Makefile command. It is sufficient to run:
+
+```bash
+make env3
+```

-/**
- * @class MemoryMap
- *
- * Represents the contents of a memory layout, with main focus into (possibly sparse) blocks of data.
- *<br/>
- * A {@linkcode MemoryMap} acts as a subclass of
- * {@linkcode https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Map|Map}.
- * In every entry of it, the key is the starting address of a data block (an integer number),
- * and the value is the <tt>Uint8Array</tt> with the data for that block.
- *<br/>
- * The main rationale for this is that a .hex file can contain a single block of contiguous
- * data starting at memory address 0 (and it's the common case for simple .hex files),
- * but complex files with several non-contiguous data blocks are also possible, thus
- * the need for a data structure on top of the <tt>Uint8Array</tt>s.
- *<br/>
- * In order to parse <tt>.hex</tt> files, use the {@linkcode MemoryMap.fromHex} <em>static</em> factory
- * method. In order to write <tt>.hex</tt> files, create a new {@linkcode MemoryMap} and call
- * its {@linkcode MemoryMap.asHexString} method.
- *
- * @extends Map
- * @example
- * import MemoryMap from 'nrf-intel-hex';
- *
- * let memMap1 = new MemoryMap();
- * let memMap2 = new MemoryMap([[0, new Uint8Array(1,2,3,4)]]);
- * let memMap3 = new MemoryMap({0: new Uint8Array(1,2,3,4)});
- * let memMap4 = new MemoryMap({0xCF0: new Uint8Array(1,2,3,4)});

Nicolas Stalder	6a288243c1	Add Makefile for installing a HID gadget The Makefile has targets for building, installing and uninstalling a HID gadget which acts as FIDO2 authenticator. Tested on Ubuntu 18.04 but should work on other distros as well. The only assumption being made is that kernel source is available at /usr/src/linux-source-$(KERNEL_VERSION).tar.bz2. A possible improvement would be to have a configure script which finds the correct kernel source archive.	2019-04-16 10:54:49 +03:00
Radoslav Gerganov	955d4f76ef	Add support for hidg devices on Linux There is a HID gadget driver on Linux which provides emulation of USB HID devices. This could be very useful for testing the Solo firmware without actual hardware, using only a Linux box. This patch adds a command line argument which specifies whether the existing UDP backing should be used or the new one which reads and writes to /dev/hidg0. Testing done: 1. Created HID device with configfs 2. Started "./main -b hidg" as root 3. Successfully executed Webauthn registration and authentication on the same Linux machine Closes: #122	2019-04-16 10:54:46 +03:00
