delta/syslinux.git/dos, branch syslinux-5.11-pre7 git.kernel.org: pub/scm/boot/syslinux/syslinux.git mem: Add magic field to detect memory corruption 2013-02-21T12:55:10+00:00 Matt Fleming matt.fleming@intel.com 2013-01-17T14:33:25+00:00 07395d946e566263525f08f31692678422976a21 Very little checking is performed on the validity of freelist metadata. Add a magic field to struct arena_header which can be used to detect memory corruption or whether a user tries to free something that isn't a malloc pointer. This feature can be enabled with -DDEBUG_MALLOC. Turn it on for development in mk/devel.mk. Cc: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>

This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>

ld: Use ABSOLUTE() when taking differences between relative symbols 2011-04-01T19:59:04+00:00 H.
