From 53f9d74322c831c76bc6cf6ed8941267e8749604 Mon Sep 17 00:00:00 2001 From: Luca Boccassi Date: Wed, 15 May 2024 01:10:35 +0100 Subject: [PATCH] elf: add note identifier for dlopen metadata This new note type is defined at https://systemd.io/ELF_DLOPEN_METADATA/ and is used to list shared library dependencies loaded via dlopen(). Distro packagers can use this, via tools like those available at https://github.com/systemd/package-notes to automatically generate dependencies when building projects that make use of this specification. By defining the note id here we can use it in other projects as a stable identifier, for example in 'readelf' to pretty-print its content.
