tools/net/ynl: Makefile's install target now installs ynltool

2026-01-21T01:10:50+00:00

This tool is built by default, but was not being installed by default when running `make install`. Fix this by calling ynltool's install target. Signed-off-by: Michel Lind Link: https://patch.msgid.link/aWqr9gUT4hWZwwcI@mbp-m3-fedora.vm Signed-off-by: Jakub Kicinski

The docs for YNL event ops currently render raw python structs.

tools: ynl: don't install tests

2026-01-08T16:46:36+00:00

make's install target is meant for installing the production artifacts, AFAIU. Don't install test_ynl_cli and test_ynl_ethtool from under the main YNL install target. The install target under tests/ is retained in case someone wants the tests to be installed.

tools: ynl: fix build on systems with old kernel headers

2025-12-09T07:53:17+00:00

The wireguard YNL conversion was missing the customary .deps entry. NIPA doesn't catch this but my CentOS 9 system complains: wireguard-user.c:72:10: error: ‘WGALLOWEDIP_A_FLAGS’ undeclared here wireguard-user.c:58:67: error: parameter 1 (‘value’) has incomplete type 58 | const char *wireguard_wgallowedip_flags_str(enum wgallowedip_flag value) | ~~~~~~~~~~~~~~~~~~~~~~^~~~~ And similarly does Ubuntu 22.04. One extra complication here is that we renamed the header guard, so we need to compat with both old and new guard define.

tools: ynl: add YNL test framework

2025-11-27T01:58:49+00:00

Add a test framework for YAML Netlink (YNL) tools, covering both CLI and ethtool functionality. The framework includes: 1) cli: family listing, netdev, ethtool, rt-* families, and nlctrl operations 2) ethtool: device info, statistics, ring/coalesce/pause parameters, and feature gettings The current YNL syntax is a bit obscure, and end users may not always know how to use it. This test framework provides usage examples and also serves as a regression test to catch potential breakages caused by future changes.
