Erez Geva, Release Engineer for the libptpmgmt Project, recently released version 1.3 of libptpmgmt. It is available via download or by pointing your ftp client to anonymous@ftp.nwtime.org.

The main features of libptpmgmt version 1.3 are:

• Authentication TLV support follows the new version of linuxptp.
• Add C language wrapper. C language applications can use the Library directly by calling the wrapper C API. For example check_ver.c, a simple C application that prints the Library version. The C API is documented in the Doxygen documents. A starting point can be found here.

The full listing of changes:

• Support LinuxPTP version 4.3.
• Add support for AUTHENTICATION.
  • Add HMAC wrapper libraries.

• Improve socket C API naming.
• Use line variable instead of a specific number in error unit test.

• Clang
  • Add support for clang.
  • Use the CC and CXX variables directly to select Clang.
  • Clang miss FLOAT_WORD_ORDER.
  • Use Clang with Gentoo CI.

• Use MIT to GO language source as there are linked in the executable.
• Fix GO message builder dependency.
• The other are used as libraries so LGPL is fine.
• Replace auto with actual type in unit test code.
• Add SPDX IDs to markdown using HTML comment and to generated Doxygen HTML and JavaScripts.
• Add traversSigTlvs to C and traversSigTlvsCl for script languages.
• Fix signalling LoopTwoManagmentTlvs unit test to loop over the 2 TLVs.
