From 895021552d6ffe8a4d076cb5c4b1e700c33e96e1 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 27 Oct 2010 15:34:09 -0700 Subject: [PATCH] coredump: default CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERS=y The userland ELF tools have been coping with partial-segments core files for a few years now. Multiple distro builds are now setting this option. It behooves everyone who ever deals with core files to have more info dumped in there, especially as more and more people's compilers are producing build IDs. Make it the default. Anyone using older tools confused by these core files can configure this option off, or just change /proc/PID/coredump_filter after boot.
