| | | | | | | | | | | | | | | | The LD_PRELOAD environment variable allows the user to specify a list of libraries which should be unconditionally loaded before any others. This makes possible some useful tricks, such as library interposers. Change-Id: I433d775ab08ef63a5fbe7b21f87a5642954fc32f

| * Fixed support for RTLD_NEXT in dlsym()Matt Fischer2010-04-083-5/+15
| | | | | | | | | | | | | | | | | | The previous implementation of this flag was broken--it behaved identically to RTLD_DEFAULT. This adds a proper implementation, which examines the address of the calling function, and uses it to determine which library to use to begin the symbol search process.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
