bootutil: Fix memory leak in HKDF implementation

The bootutil_hmac_sha256_set_key routine performs some dynamic memory
allocations when mbedTLS is used. To properly free the allocated memory,
bootutil_hmac_sha256_drop must be called before reinitializing the HMAC
context using bootutil_hmac_sha256_init.  However, in the hkdf routine,
the HMAC context was freed only once even though it was initialized
multiple times.

MCUboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Build Status (Espressif) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is MCUboot version 2.1.0-dev

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a common infrastructure for the bootloader and the system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software upgrade.

MCUboot is not dependent on any specific operating system and hardware and relies on hardware porting layers from the operating system it works with. Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any new port contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with different operating systems and SoCs:

There are also instructions for the Simulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
