From db6b35cffe59c619ea3772b21d7c7c8a7b885dc1 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Sat, 6 Dec 2025 17:38:48 -0800 Subject: [PATCH] tools: ynl: fix build on systems with old kernel headers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
