From f91f1c0fb89056995f1c9c6a06c361efdf5139e7 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 28 Jun 2013 16:20:26 +0100 Subject: [BZ #15022] Correct global-scope dlopen issues in static executables. This change creates a link map in static executables to serve as the global search list for dlopen. It fixes a problem with the inability to access the global symbol object and a crash on an attempt to map a DSO into the global scope. Some code that has become dead after the addition of this link map is removed too and test cases are provided. --- dlfcn/modstatic3.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 dlfcn/modstatic3.c (limited to 'dlfcn/modstatic3.c') diff --git a/dlfcn/modstatic3.c b/dlfcn/modstatic3.c new file mode 100644 index 0000000000..cd24986f23 --- /dev/null +++ b/dlfcn/modstatic3.c @@ -0,0 +1,31 @@ +/* DSO used for dlopen testing with a static executable. + Copyright (C) 2013 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
