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.

2010-04-11ldso_sh: Provide only one definition for elf_machine_type_classCarmelo Amoroso
It doesn't need to provide different definition of elf_machine_type_class macro depending on TLS support. It also fixes build for sh architecture when thread support is off: CC ldso/ldso/ldso.oS In file included from ./ldso/ldso/sh/dl-sysdep.h:9, from ./ldso/include/dl-string.h:11, from ./ldso/include/ldso.h:40, from ldso/ldso/ldso.c:33: ./include/tls.h:6:22: error: tls.h: No such file or directory make: *** [ldso/ldso/ldso.oS] Error 1 Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-12-17check if USE_TLS is defined before useHans-Christian Egtvedt
This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

2009-12-03ldso_tls: Refetch dtv from memory if THREAD_DTV has changedCarmelo Amoroso
_dl_update_slotinfo might change THREAD_DTV () (if it needs to reallocate it), but the caller (__tls_get_addr) doesn't refetch dtv from memory, it uses its cached copy. This may crash (if dtv[GET_ADDR_MODULE] is off the cliff, or might read uninitialized memory and return it. Typically dtv[GET_ADDR_MODULE].pointer.val is NULL and so __tls_get_addr returns NULL + offset_within_PT_TLS. The next time __tls_get_addr is called for the same library it will return correct address as _dl_update_slotinfo won't need to be called.
