2012-06-15__uClibc_main.c: do not include unused headersPeter S. Mazinger
Remove unneeded headers. Guard inclusion of fcntl.h. While there, remove an obsoleted comment. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-15errno and *_init cleanupPeter S. Mazinger
Define a common view of __errno_location, __h_errno_location in common header and use that everywhere, __uClibc_main.c is no special. The rule adopted: for enabled threads we make in libc the __GI_x() variants strong, x() weak and (should) provide another strong x() in libpthread. If threads are disabled, even the __GI_x() variants are weak. _stdio_init,_stdio_term,_locale_init: make all hidden weak in common header Signed-off-by: Peter S.

2010-10-14config parser: always initialize line pointerNatanael Copa
We must always initialize line pointer since data pointer might have changed due to a realloc (in getserv.c for example). Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-10-14config parser: do not assume that realloc return same pointerNatanael Copa
We need to update the parser->line pointer on realloc and do not initialize the token array til after the potensial realloc in bb_get_chunk_with_continuation(). While here, also replace a realloc() with malloc() where pointer always is NULL. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.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>

2010-08-06config parser: fix memory corruptionTimo Teräs
fgets will happily write over allocated area limits. Adjusted the buffer size according to how much is already read. Also increase the maximum default line length, as 80 is slightly small. It might be better if bb_get_chunk_with_continuation would reallocate the line buffer if it was not user given.

2010-07-05don't make __errno_location / __h_errno_location hiddenPeter Korsgaard
Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089) __errno_location / __h_errno_location access has to go through the PLT like malloc/free, so the linuxthread variants gets used instead when compiling with -pthread.

2010-05-07static build: fix internal locking weaks to get pulled in alwaysTimo Teras
Linker is smart and does not pull in weaks.os, ever. This happens because that compilation unit does not get strong references and ld eliminates dead code. We really need the weaks for static build in a compilation unit that is always there, otherwise it won't work.
