* bionic/linker: keep track of opened libraries by basenameandroid-sdk-tools_r2android-sdk-1.6_r2android-sdk-1.6_r1android-sdk-1.6-docs_r1android-1.6_r2android-1.6_r1.5android-1.6_r1.4android-1.6_r1.3android-1.6_r1.2android-1.6_r1.1android-1.6_r1Erik Gilling2009-07-281-2/+6
| | | | | | | | | | | | | | | | | | | | | | | Prior to this change, the dynamic loader kept track of opened libraries either by their base name (i.e., libfoo.so instead of /system/lib/libfoo.so) when the shared library was loaded through the DT_NEEDED tag in an ELF header, or by whatever name was passed to dlopen(). This created a number of problems, among which: 1. dlopen("libfoo.so") and dlopen("/path/to/libfoo.so") would open the same library twice; 2. dlopen("/path/to/libfoo.so") and then dlopen("libbar.so"), where libbar.so depends on libfoo.so, would open libfoo.so twice. This patch makes the dynamic loader keep track of each loaded library by basename, which resolves the above ambiguity. The patch also enforces library lookup by base name, which means that it will refuse to load another library that has the same name. Thanks for the inspiration Iliyan.

* | Make the DNS resolver accept domain names with an underscore.David 'Digit' Turner2009-07-271-1/+8
|/ | | | | | | More precisely, this accepts domain labels with an underscore in the middle (i.e. not at the start or the end of the label). This is needed to perform complex CNAME chain resolution in certain VPN networks.
* Restore malloc debug.Andy McFadden2009-07-214-16/+21
| | | | | | Some libc changes were preventing the initialization call from being made. The basic problem appears to be that libc_init_common.c is only built once, and it's only built for the non-debug libc.
* Fix the C library runtime initialization order.David 'Digit' Turner2009-07-184-100/+115
| | | | | | | | | | | This allows libc.so to run the C runtime initializer as soon as the dynamic linker loads the shared library, i.e. before any other initializers (e.g. static C++ constructors in other shared libraries the executable depends on). This also removes the bug where the initializers from the executable itself were run twice: once by the dynamic linker, and another time by __libc_init as defined by libc_init_dynamic.c
* Pass the elfdata pointer in a slot of the temporary TLS area.David 'Digit' Turner2009-07-172-7/+21
| | | | | | | | | | | | | | | | This is needed to properly initialize the C runtime when libc.so is loaded by the dynamic linker. Move the temporary TLS setup before the first system call, just in case something really horrible happens, we won't crash when trying to write an error code in 'errno' Remove the broken TLS_SLOT_THREAD_ID setup. First, this slot should normally receive the address of a pthread_internal_t, not a kernel thread identifier. Second, it is never used by the linker anyway. Also remove an obsolete comment.

* | Fix the C library initialization to avoid calling static C++ constructors twice.David 'Digit' Turner2009-06-0211-94/+273
|/ | | | | | | | | | | | | | | | | | | | | | | | | | The problem was due to the fact that, in the case of dynamic executables, the dynamic linker calls the DT_PREINIT_ARRAY, DT_INIT and DT_INIT_ARRAY constructors when loading shared libraries and dynamic executables, *before* calling the executable's entry point (i.e. arch-$ARCH/bionic/crtbegin_dynamic.c) which in turns call __libc_init() in libc.so, as defined by bionic/libc_init_dynamic.c The latter did call these constructors array again, mistakenly. The patch also updates the documentation of many related functions. Also adds a new section to linker/README.TXT explaining restrictions on C library usage. The patch has been tested on a Dream for stability issues with proprietary blobs: - H264 decoding works - Camera + Video recording works - GPS works - Sensors work The tests in system/extra/tests/bionic/libc/common/test_static_cpp_mutex.cpp has been run and shows the static C++ constructor being called only once.

* linker: Make the errors reported by dlopen/dlsym be more useful.Dima Zavin2009-05-275-67/+106
| | | | | | | | | | | | | Changed it so that when the linker generates error messages, they are scribbled away into a buffer that dlfcn and friends can read from. Since the error messages are generetad with snprintf, and snprintf MAY call malloc during some code paths, we now link against a version of libc that does not contain malloc/free/realloc/calloc. We then define malloc and friends in the dynamic loader, and make them abort() if they are ever called. Signed-off-by: Dima Zavin <dima@android.com>

* change getaddrinfo() implementation to match GLibc.David 'Digit' Turner2009-05-051-2/+6
| | | | | | | | | | | | | | the issue is that the BSD implementation doesn't accept a call like: getaddrinfo(SERVER_NAME, "9999", NULL, &res); because if will reject a numerical string in the second parameter if no hints are explicitely provided. This technically doesn't violate POSIX but might make porting Linux software a bit difficult.
