| | | | | | | | | | | | | | | | dladdr() is a GNU extension function, which allows the caller to retrieve symbol information for a specified memory address. It is useful for things like generating backtrace information at runtime. Change-Id: I3a1def1a6c9c666d93e1e97b7d260dfa5b9b79a9

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a mini-printf implementation that reduces the size of the dynamic linker by 25 KB, by preventing the drag of formatting-related routines from the C library. Also allow traces to be sent to the log, instead of stdout. NOTE: You now need to modify Android.mk to enable/disable debug output.

* | bionic/linker: fix symbol lookup during relocationsIliyan Malchev2009-09-271-26/+74
| | | | | | | | | | | | | | | | | | When resolving relocations while loading a library, the linker used to find symbols by looking them up in the list of all linked libraries for the current process, as opposed to following just the library's DT_NEEDED entries. This can cause a problem where the symbol is picked up from the wrong library. Signed-off-by: Iliyan Malchev <malchev@google.com>

* 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.

* Pass the elfdata pointer in a slot of the temporary TLS area.David 'Digit' Turner2009-07-171-7/+14
| | | | | | | | | | | | | | | | 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.

* 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>
