v0.3.1

Mostly bug fixes and preparation to use in Stratum.

How to update from v0.3.0

There are no changes at C API or CLI level, so update should be straightforward.

Now cmake will check for dependencies installation. If dependencies are installed in a non-standard location, some errors may occur when invoking cmake.

What's Changed

• Make pipeline information more accurate by @tatry in #87
• Invalid byte order on single entry get in Counter, Meter and Register by @tatry in #88
• Lower minimum required cmake version by @tatry in #92
• Add extern "C" clause to the public header files by @tatry in #93
• Refactor CMakeLists.txt. Add custom target for headers installation by @tatry in #94

Full Changelog: v0.3.0...v0.3.1

v0.3.0

Mostly bug fixes and improvement release. There are introduced two main new features:

• Added Dockerfile for docker images.
• Fixed support for fields wider than 64 bits.

How to update from v0.2.0

There are no changes at C API or CLI level, so update should be straightforward.

The one thing which could be considered is that fields wider than 64 bits have network byte order in dataplane. Using BTF mode byte order is handled by the library and is transparent, so behaves as usual. Without BTF mode byte order is not changed for such fields, so you have to change it on your own.

What's Changed

• Update README after renaming by @osinstom in #74
• Allow read register without entries by @tatry in #78
• Improve resource management in value_set API by @tatry in #79
• Improve documentation by @tatry in #76
• Add mailing list and other modifications to README by @osinstom in #83
• Add Dockerfile for NIKSS by @osinstom in #81
• Fix linter checks on new runners using Ubuntu 22.04 by @tatry in #86
• IPv6 CLI parser and support for wide fields in network byte order by @tatry in #80

Full Changelog: v0.2.0...v0.3.0

v0.2.0

Starting from this release we use new project name nikss.

How to update from v0.1.0

There is no changes in behavior of our library, so there is no need to change application logic.

Follow steps below to update:

• (Recommended): Remove existing installation to avoid confusions. Because generated makefile doesn't provide uninstall target, files have to be removed manually. Files to be removed, assuming default prefix /usr/local, are:

  • /usr/local/bin/psabpf-ctl
  • /usr/local/lib/libpsabpf.so (if option -DBUILD_SHARED was set to on)

• Build and install library as described in README.md.

• New project name causes new prefix for all API objects, so scan your code and replace all occurrence of (case sensitive):

  • psabpf into nikss
  • PSABPF into NIKSS
  • PSAeBPF into NIKSS (if python scripts are used)

  If something doesn't work let's see PR #73 and check how it was changed.

What's Changed

• Rename psabpf to NIKSS by @tatry in #73

Full Changelog: v0.1.0...v0.2.0

v0.1.0

We switch to the new project name nikss from psabpf for our library, so this is the latest version that uses name psabpf.
