  • Add the first version of the Clock Manager A framework for controlling and monitoring network time synchronization on the local platform.
  • Rewrite PHC control tool in Go. Implement linuxptp 'phc_ctl' using the Go wrapper library.
  • Replace 'select' with 'poll'.
  • Improve proc functions
    • base integer proc functions
    • Managment TLVs wuth vector
  • HMAC add load and unload to improve safe multi-threads Control the load and unload from the hmac module, with uses mutex for multi-threads protection. Use macros for C wrapper function in source module.
  • use one line for short functions
  • remove go.mod from packages
  • Lua use arg[0]
  • Improve use of strerror() and remove '%m' format
  • Debian Go and PHP are always supported
  • always link the PMC tool with shared library
  • Improve Binary::fromIp, use inet_aton() that support more IPv4 string notations.
  • Improve PMC libsy printf wrappers
  • Rename proc.h, sig.h to mngTlvs.h, sigTlvs.h.
  • Add support for extended format of L1_SYNC TLV
  • More Improvements that breaks ABI backwards-compatible
  • Improve message to JSON string creating.
    • Use structure to hold the string.
    • comply to other structures way.
  • Improve C dispatcher and add C builder.
    • Remove all direct functions and use methods instead.
    • Use the new TLV memory for builder.
    • Move TLVs callbacks into a separate structures.
    • call virtual functions from inline function, so we compile it in the application and avoid using virtual functions table directly from library code.
  • Improvements in C++ to C TLV conversions
    • Improve use of LinuxPTP event methods.
    • Add size of data to C ORGANIZATION_EXTENSION Tlv.
    • Add table size to C PATH_TRACE_LIST_t Tlv.
  • MessageSigTlvs: Add copy and move constructors
    • Add copy and move to MANAGEMENT_t.
    • Any class that uses unique pointer should implement copy and move constructors explicitly.
    • MessageSigTlvs need explicit, as the last Signalling flag can save copying or move of the Signalling TLVs list.
    • Repair TLVs structure by converting constant parameters to static constant. non static constant parameters fails copy. In addition to space waste in structure object itself.
  • PTP types
    • Move code of types from message to a new types module.
    • Convert size inline methods to non-inline.
    • Add M4 macros for flags for proc and sig headers.
  • Move ConfigSection into ConfigFile.
  • Move protected methods to private for final socket classes.
  • Unit tests
    • Rename variable in HMAC to avoid error in newer C++ standard
    • Reorder of functions in PMC build
    • Remove unused map in libsys
  • Move distributions packages to the distclean list Spellings
  • Prepare for for second major version
  • Clean-up function kept for ABI compatibility
    • Remove ABI backward compatibility functions.
    • Remove deprecated functions.
    • Convert inline public methods to non-inline.
  • Rename libraries for new major version.
  • Add more constants
  • Use constant for input only parameters.
  • Use constant methods when the object remain unchanged.
  • Sockets:
    • Add missing check for initialisation state.
    • Change get home directory to static method as it depends on application user context and not on a specific object.
  • Change default UDS address after LinuxPTP.
  • Add next Debian release forky.
  • Improve install in make file
  • Fix GO Make File
    • Probe touch with configure
    • Add missing touch of go.sum
  • Fix generated SPDX in make file
  • C++ replace 'data' with other names. It seems conflict in C++ 17.
  • Google test update to C++ 17
  • Fix Debian docker file. Make sure it exit with error properly.
  • Use 'cmark' for converting markdown to html in some cases, Apparently some markdown are converted better with the legacy 'markdown' tool, While some are better with the 'cmark' tool.
  • Move the code that add SPDX from Makefile to a separate script. Add SPDX to Clock Manager Doxygen documents as well as to the pages site.
  • Improve ruby probing in autoconf, compile with the ruby header
  • Add the CommonMark tool with GitHub Flavored Markdown converter.
  • Fix criterion probing in autoconf, add the standard integer header.
  • Remove all github and gitlab directories from tar file.
  • Fix HMAC after Coverity reports.
  • Show the compiler output for both PIC and non-PIC objects of src/hmac.cpp, as the code is different.
  • Proper handling of sending key HMAC instance
  • Add Binary::mvBin for rvalue.
  • Improve vector and use of move.
  • SaFile: No need to call clear before new assignment.
  • tlv_mem: use allocations vector with a class releasing the memory on destructor, similar to unique_ptr.
  • Add Binary move constructor.
  • Binary assign: protect against self assign.
  • If we use copy constructor, we should also add a move constructor.
  • Add getTlv() to MessageSigTlvs.
  • Order MessageSigTlv code in place.
  • Add a test for coping a management TLV. Ensure the copy works in C++.
  • Rebase signalling TLVs list in message. Add range based loop support.
  • JSON Parser: add to string. Add more tests. Replace find with equal_range.
  • Improve TLV C to C++ and via versa.
  • Add Iterator to JSON Array class.
  • Add missing test for sockets initialisation state.
  • Delete without checking for null.
  • Remove inline methods of JSON parser.
  • Mark local functions of message module as inline.
  • Improve handling of reallocation in TLV memory.
  • Remove testing of reallocation with ASAN test. As it fail to probe it correctly.
  • Add C TLV structure to track memory allocations.
  • Improve process of TLVs.
  • Add helper functions from C++ to C and via versa conversions.
  • Add limit to PTP Text length.
  • Improve C dispatcher. Use interface to manipulate the dispatcher object. So we improve backward compatibility better.
  • Follow Miroslav Lichvar last commit.
    • Add EXTERNAL_GRANDMASTER_PROPERTIES_NP management message to get and set the new external grandmasterIdentity and stepsRemoved variables of the clock.
    • Together with the GRANDMASTER_SETTINGS_NP message all grandmaster-specific values in announce messages can be now set.
    • Add PORT_CORRECTIONS_NP management message to get and set the port egressLatency, ingressLatency and delayAsymmetry variables. This enables an external process to compensate for changes in the network and timestamping asymmetries while ptp4l is running.
  • A fix in JSON to message unit test.
  • Add libchrony probing.
  • Fix go wrapper make file. Check go executable available before using it.
  • Probe Google test mock header.
  • Fix cross compilation on Debian trixie container. New TCL uses Linux path instead of multiple lines.
  • Improve using standard vector.
  • Fix phc_ctl help follow Linuxptp.
