2016-06-22ldso: fix dlsym hang when reloading DSOsLeonid Lisovskiy
It can happen under certain cases that the DSO had refcount 0, but was already loaded. (NODELETE flag is set, or it is pulled in via both NEEDED dependency and explicit dlopen()). Add extra reference count for NODELETE objects, this will ensure that the reference count never drops below one. It is improved version of http://lists.busybox.net/pipermail/uclibc/2013-June/047826.html Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com>

2016-01-31libdl: dlopen() mustn't forget RTLD_NODELETE flagLeonid Lisovskiy
If RTLD_NODELETE is passed to dlopen() rather than set on shared library itself, flag propagation to rtld_flags is missed. Test-case taken from glibc. Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com> Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2012-02-07tests:libdl: add a new test for symbol scope issue in dlcloseFilippo ARCIDIACONO
Test case to trigger an issue raised by the new symbol scope design, that was erroneously removing local symbol scope from the global one too early while dl-closing a shared library.

2009-12-09test_dlopen: Remove extra -lpthread from LD_FLAGS for dltest{2}Filippo Arcidiacono
dltest and dltest2 do not refer any symbols implemented in pthread library, so do not explicitly link them with pthread. It is required only for the shared objects that are loaded via dlopen by those tests.

2009-03-16Fixed makefiles inclusion flow to pass actual configuration variable values.Carmelo Amoroso
Test build system modified to be similar to uClibc one: * test custom logic moved from Makefile to a new Makefile.in (to be included by Makefile). * Makefile same for all tests and just used for including all other needed makefiles.
