2010-09-17ldso: Add runtime prelink supportFilippo Arcidiacono
Added runtime prelink support to be able to run a prelinked application; at process startup only the conflicts will be relocated. This speed up the startup time. Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-09-17ldso: Add implementation of ld.so standalone executionFilippo Arcidiacono
The dynamic linker can be run either indirectly through running some dynamically linked program or library (in which case no command line options to the dynamic linker can be passed and, in the ELF case, the dynamic linker which is stored in the .interp section of the program is executed) or directly by running: /lib/ld-uClibc.so.* [OPTIONS] [PROGRAM [ARGUMENTS]] Stand-alone execution is a prerequisite for adding prelink capabilities to uClibc dynamic linker, as well useful for testing an updated version of the dynamic linker without breaking the whole system. Currently supported option: --library-path PATH use given PATH instead of content of the environment variable LD_LIBRARY_PATH (Mandatory for prelinking) Not supported options: --list list all dependencies and how they are resolved --verify verify that given object really is a dynamically linked object we can handle --inhibit-rpath LIST ignore RUNPATH and RPATH information in object names in LIST This feature can be enabled by setting LDSO_STANDALONE_SUPPORT=y Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-09-15libubacktrace: Provide uClibc with backtrace functionsSalvatore Cro
A new shared object, libubacktrace.so.0 is added to uClibc to provide backtrace functions to support application self-debugging. This set of functions requires to dynamically load libgcc_s.so so they need to call dlopen/dlsym that are provided by libdl. For this reason they cannot be included into libc.so.0 but are provided by a new library. User application that wants to use backtrace needs to be compiled with -fexceptions option and -rdynamic to get full symbols printed and must be linked against libubacktrace.so Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-04-14ldso: Add config option for controlling LD_PRELOADCarmelo AMOROSO
On hardened system it could be useful to disable the use of LD_PRELOAD environment variable for preloading shared objects before the system libraries. So this patch add a config option, LDSO_PRELOAD_ENV_SUPPORT, to control this behaviour. It is enabled by default.

2009-07-26enable sbrk() for everyoneMike Frysinger
The sbrk() function can be used to merely query sizes and for that, no-mmu works the same as mmu. It can also sometimes increase data segments on no-mmu systems provided the trailing memory is free. So, there is no real reason to exclude this function for no-mmu ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
