From 29f756e3fba09f6a66515970978367829862f35c Mon Sep 17 00:00:00 2001 From: Panu Matilainen Date: Thu, 5 Jan 2017 12:13:54 +0200 Subject: [PATCH 10/54] Only process regular files when generating build-ids Versioned shared libraries typically have several symlinks pointing to them directly and indirectly. When %_build_id_links is set to compat or separate this causes bogus warnings about duplicate build-ids. It looks commit bbfe1f86b2e4b5c0bd499d9f3dd9de9c9c20fff2 intends to skip symlinks since it filters on S_ISREG(), but since uses fstat() on already open()'ed file it ends up stat()'ing the symlink target. Flip stat() + open() around and use lstat() instead to fix it.
