* ldso: support RTLD_NODELETE and DF_1_NODELETETimo Teräs2010-04-223-13/+22
| | | | | | | | | Honor the nodelete flags so we don't delete shared library if it's sticky. This is useful for libpthread if it gets pulled in by a dlopen'ed library. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* nptl: proper soname handlingNatanael Copa2010-04-222-4/+4
| | | | | | | | | | | Since sublevel releases are not ABI compatible we need to adjust the soname to include the sublevel version. This makes it possible to install ABI incompatible versions of the library side by side so clean upgrades are possible.

| * ldso: Add config option for controlling LD_PRELOADCarmelo AMOROSO2010-04-141-0/+8
| | | | | | | | | | | | | | | | | | | | | | 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.

* | ldso_tls: Refetch dtv from memory if THREAD_DTV has changedCarmelo Amoroso2009-12-031-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _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.

| | | | | | | | | | | | | | | | | | Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems.
