From a1b85ae88b1a664e93ca0182c82f7763dd5a1754 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 9 Nov 2015 16:52:31 +0100 Subject: ld.so: Add original DSO name if overridden by audit module [BZ #18251] * elf/dl-load.c (_dl_map_object_from_fd): Add additional parameter for original name of the DSO. Add it to the name list of the DSO if it is actually given. (_dl_map_object): Keep track of whether an audit module rewrote the file name. If yes, pass the original name to _dl_map_object_from_fd in a new parameter, otherwise NULL. When debugging is enabled, log the change of the file name. * sysdeps/mach/hur/dl-sysdep.c: Adjust commented-out call to _dl_map_object_from_fd. * elf/Makefile: Build and run tst-audit11 and tst-audit12. * elf/tst-audit11.c: New file * elf/tst-auditmod11.c: New file. * elf/tst-audit11mod1.c: New file. * elf/tst-audit11mod2.c: New file. * elf/tst-audit11mod2.map: New file. * elf/tst-audit12.c: New file * elf/tst-auditmod12.c: New file. * elf/tst-audit12mod1.c: New file. * elf/tst-audit12mod2.c: New file. * elf/tst-audit12mod2.map: New file. * elf/tst-audit12mod3.c: New file. --- elf/tst-audit11.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 elf/tst-audit11.c (limited to 'elf/tst-audit11.c') diff --git a/elf/tst-audit11.c b/elf/tst-audit11.c new file mode 100644 index 0000000000..15a44f9ec6 --- /dev/null +++ b/elf/tst-audit11.c @@ -0,0 +1,36 @@ +/* Test version symbol binding can find a DSO replaced by la_objsearch. + Copyright (C) 2015 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.
