avs_commons 5.4.5

Improvements

• Added support for Mbed TLS 3.6

avs_commons 5.4.4

Features

• Added custom base64 encoding without null terminating
• Added API to modify extended attributes in Certificate Signing Request

avs_commons 5.4.3

Improvements

• Optimized "Out of memory" logs in favor of a smaller flash memory footprint

Bugfixes

• Fixed "unused assignment" warning generated by static analyzers when compiling
  against Mbed TLS 3.x

avs_commons 5.4.2

Features

• Refactored the PRNG integration in the Mbed TLS backend so that the PSA RNG
  API can be used if CTR-DRBG and/or entropy APIs are disabled

Bugfixes

• Additional validation in avs_persistence_string() to avoid restoring a
  string with superfluous data after the nullbyte

avs_commons 5.4.1

Bugfixes

• Fixes in CMake scripts when searching for mbed TLS in the case when MBEDTLS_ROOT_DIR, CMAKE_FIND_ROOT_PATH and CMAKE_FIND_ROOT_PATH_MODE_* are all specified explicitly
• Fixes in some #ifdef directives that caused compilation failures when AVS_COMMONS_WITH_AVS_CRYPTO_PSK was disabled

avs_commons 5.4.0

BREAKING CHANGES

• Default POSIX socket implementation now doesn't include errno.h if
  definition of EDOM (available by e.g. including lwIP's lwip/errno.h)
  is included in AVS_COMMONS_POSIX_COMPAT_HEADER.

Improvements

• Made MD5 length define publicly visible (for easier avs_stream_md5 usage)
• Made (D)TLS session resumption and persistence possible on Mbed TLS 3.0+ even
  when MBEDTLS_SSL_SRV_C is disabled

Bugfixes

• Added missing null guards in (D)TLS socket implementations so that all methods
  are now safe to call in any state
• When using lwIP, default POSIX socket implementation and appropriate compat
  header now include lwIP's lwip/errno.h instead of system errno.h

avs_commons 5.3.1

Features

• Added AVS_NET_SOCKET_OPT_PREFERRED_ADDR_FAMILY and
  AVS_NET_SOCKET_OPT_FORCED_ADDR_FAMILY options that allow setting address
  family configuration of an already created socket
• Automatically upgrading IPv4 sockets to IPv6 when connecting is now possible
• Added AVS_UNIT_MOCK_DECLARE() and AVS_UNIT_MOCK_DEFINE() to facilitate
  declaring mocked functions with external linkage

Improvements

• Slightly changed the semantics of avs_sched_run(), to fix erroneous
  behavior on platforms with low-resolution system clocks

avs_commons 5.3.0

Features

• Added the AVS_COMMONS_NET_POSIX_AVS_SOCKET_WITHOUT_IN6_V4MAPPED_SUPPORT
  configuration option that improves dual-stack IPv4+IPv6 connectivity on
  platforms that do not support IPv4-mapped IPv6 addresses (::ffff:0:0/96)

Improvements

• Trivial fixes to silence warnings on certain commercial compilers
  (contributed by Flonidan A/S)
• Removed usages of most deprecated Mbed TLS and OpenSSL APIs

avs_commons 5.2.0

BREAKING CHANGES

• Removed avs_unit_memstream that is now unused

Features

• Added persistence of DTLS context state related to the Connection ID extension
  and the related AVS_NET_SOCKET_OPT_CONNECTION_ID_RESUMED option
• Added option to set avs_log logging level in compile time. If
  AVS_COMMONS_WITH_EXTERNAL_LOG_LEVELS_HEADER is specified, inactive logs will
  be removed during compile time
• Added option to disable log level check in runtime, if active the macros
  avs_log_set_level and avs_log_set_default_level are not available

Improvements

• Avoid calling avs_net_socket_send() with zero-length buffers when using
  avs_stream_netbuf

Bugfixes

• Fixed out_message_finished and out_bytes_read not being set when
  read is called with a NULL buffer in avs_stream_inbuf

avs_commons 5.1.3

Improvements:

• Added support for setting MTU in the Mbed TLS backend
• Added the "alignfix" alternate memory allocator

Bugfixes:

• Fixed tls session persistence flag
• Removed calling mbedtls_ssl_ciphersuite_uses_psk() if PSK is disabled in Mbed TLS
