roy d76886af8e Fix build with clang. 2020-09-29 16:34:07 +00:00
kamil 8f03799314 Add new RTLD test file for r_debug 
New tests:
 - self
 - dlopen

Both check whether the r_debug structure seems to be well-formed, without
and with a dlopen(3) call.

skrll bda3cfd2fc Disable attempt to use ifunc on hppa. It doesn't work and new binutils 
throws a build error.

maya 36592171e1 return return atf_no_error() instead of 0 for consistency. 
suggested by moritzbuhl in https://github.com/NetBSD/src/pull/11/

christos 292b510fe2 clang ifunc's on powerpc require secure-plt. 2019-05-14 19:07:07 +00:00
joerg d3d2a5f92e Avoid casting fun by switching ifunc helper functions to return 
long long. Dead beef is too useful to switch to a different constant.

maya f076331dd4 Build less of the test code if there's no linker ifunc support. 
r1.6 changed the code in such a way that it was hitting a BFD assert on
MIPS, causing the builds to fail.

we were hitting the assert at binutils/dist/bfd/elfxx-mips.c:10879

martin d2225bb82b Skip all tests on architectures w/o ifunc linker/ld.elf_so support. 2017-12-30 16:53:34 +00:00
joerg da03f1ef14 init/fini for the main program is handled by crt0.o, so ifunc handling 
is skipped right now as it iterates the same list. Don't repeat that
mistake and explicitly take care of it in the dynamic linker.

joerg 610e531ea3 Add sparc/sparc64 support for irelative relocations. 2017-08-12 09:03:27 +00:00
joerg e78cfb8eb8 Add IRELATIVE support for ARM, X86 and PowerPC. 2017-08-10 19:03:25 +00:00
joerg df826237c7 Avoid a race condition between dlclose and thread termination. 2017-07-21 16:39:20 +00:00
joerg e5678be828 Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This 
functions are used for destructors of thread_local objects.

If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.

Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

christos c54cb81102 Don't play with "../.." in includes for h_macros.h; deal with it centrally. 
Minor fixes.
 2017-01-13 21:30:39 +00:00
joerg 6c18385369 Really revert to the original version. 2014-08-26 17:13:42 +00:00
joerg 497e202f2a Revert. There is no such thing as __HAVE_IFUNC and there should not be 
one in first place.

christos 5a3404e066 effectively disable the test to fix the build and explain why. 2014-08-26 11:10:02 +00:00
joerg 7a1a6f1cf3 Add basic support for indirect functions. It allows providing a public 
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.

Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

Inspired by FreeBSD's r228435 by kib@freebsd.org.

joerg d0ebb0ebfa ARM now works with integrated-as. 2014-02-14 20:33:32 +00:00
joerg 1fd04761e2 Disable integrated-assembler for clang on ARM for two files that are 
victims of the @ comment mess on that platform. Add a reference to the
upstream PR.
 2013-12-25 22:26:35 +00:00
joerg 71d0bcc69f Introduce __HAVE_NO___THREAD for sun2 and vax to disable the TLS usage. 
Require __HAVE_TLS_VARIANT_I or __HAVE_TLS_VARIANT_II as well as
__lwp_getprivate_fast / __lwp_gettcb_fast to exist for libpthread.
Define VAX as going to use TLS variant I, if it is ever implemented.

pooka 8498f8450d test helper program exit code, not test program exit code 2010-12-31 08:52:32 +00:00
skrll f1d73a2c94 Add support for DF_1_BIND_NOW, DF_1_NODELETE and DF_1_NOOPEN marked 
objects, and the RTLD_NODELETE and RTLD_NOLOAD flags to dlopen(3).

Mark libpthread as DF_1_NOOPEN and use it to test the functionality.

Somewhat taken from FreeBSD.

Fixes PR 42029.

OK from christos and joerg.

skrll be2356ad6f Convert a couple of old regress tests to ATF. 
Remove the regress/usr.bin/rtld/dlopen/dlopen.c test as well as it's
covered by existing ATF test(s).

christos 0f10aa9dce add Makefile.inc everywhere so that we can set WARNS=4 by default. Amazing 
how many bugs this found :-)
