2008-01-09fix broken whitespace in many places; no functional changesMike Frysinger
2007-12-03Blackfin FD-PIC patches 5/6.Bernd Schmidt
A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run.
2007-12-03Blackfin FD-PIC patch 2/6.Bernd Schmidt
Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names.
2007-12-03Blackfin FD-PIC patch 1/6.Bernd Schmidt
Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.
2007-11-16If uClibc's ld.so encounters text relocations in a shared library - one Carmelo Amoroso
containing an object built without -fpic/-fPIC - then: * If __FORCE_SHAREABLE_TEXT_SEGMENTS__, then it gives an error "Can't modify %s's text section. Use GCC option -fPIC for shared objects, please.\n" and exits. * Otherwise, it makes the library's pages writable and relocates it. If it encounters text relocations in a position-independent executable - one containing an object built without -fpie/-fPIE/-fpic/-fPIC - then: * If __FORCE_SHAREABLE_TEXT_SEGMENTS__, it does nothing about making the pages writable, leading to a crash. * Otherwise, the loop to make the pages writable uses the same variable ppnt as used in an outer loop, messing up that outer loop and also causing a crash. This patch fixes both cases, by giving an error if __FORCE_SHAREABLE_TEXT_SEGMENTS__ and saving and restoring ppnt otherwise. Tested in both cases on ARM EABI. Joseph S. Myers joseph@codesourcery.com

Currently a static libdl.a doesn't run all the constructors or destructors of the libraries it loads. I can't see a good reason for that, and it does cause aborts in the destructors it does run for things like libgcc.so on the Blackfin. Fixed with the patch below - untested in mainline, but the equivalent has been in our Blackfin tree for a while now.

in ldso/ldso.c, function _dl_get_ready_to_run, the variable app_tpnt_tmp is not initialized. The function _dl_parse_dynamic_info() initializes some of their members but not all. For example, if the binary does _not_ contain a DT_TEXTREL record, it is possible that the condition if (app_tpnt->dynamic_info[DT_TEXTREL]) is nevertheless true and we therefore enter the following code path (ldso.c:270). My suggestion is to add _dl_memset(&app_tpnt_rel, 0, sizeof(app_tpnt_rel)); just behind the variable declarations of _dl_get_ready_to_run().

2005-09-08Fix by Martin Schlemmer:Mike Frysinger
If _DL_FINI_CRT_COMPAT is defined, _dl_fini is setup to run at exit via atexit(), but this makes it run _before_ the fini (__app_fini()) of the app, causing stuff like sandbox that frees structs, etc via its fini to segfault. http://bugs.gentoo.org/98187
