* Add Makefile support for DSBT ELF.Bernd Schmidt bernds_cb1@t-online.de2011-03-051-0/+1
| | | | | | | | | | | This adds support for a new binary format, DSBT ELF, to the Makefiles. Every shared library is assigned a DSBT index, and the link.so macro is adjusted to ensure the correct linker argument is passed. Configuration and ldso support will follow in separate commits.

* Add protected symbols support for all architecturesSalvatore Cro2011-01-201-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Protected symbols are global symbols for which interposition is not allowed. We manage them in generic _dl_lookup_hash function. To handle protected symbols we need to get a reference to the module that defines the symbol itself. So we pass a new parameter 'struct symbol_ref' to the __dl_lookup_hash that is defined as below: struct symbol_ref { const ElfW(Sym) *sym; struct elf_resolve *tpnt; }; The tpnt field is used as an ouput parameter and refers to the module which defines the protected symbol. Further it can be used as output parameter for TLS relocations and FDPIC case. The sym field is instead used as an input parameter to detect the visibility of the symbol we are looking-up. In this way we get rid of different signatures for _dl_lookup_hash, allowing to remove the _dl_find_hash wrapper. This new structure is also suitable for prelink integration.

* nptl: proper soname handlingNatanael Copa2010-04-221-1/+1
| | | | | | | | | | | 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.

* check if USE_TLS is defined before useHans-Christian Egtvedt2009-12-171-10/+10
| | | | | | | | | | | 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.

* Blackfin FD-PIC patch 3/6.Bernd Schmidt2007-12-031-1/+1
| | | | | | | | | | | | | | | Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch. _dl_find_hash is now a wrapper function around it; unlike on the NPTL branch, it retains the old interface so that not all callers need to be changed. _dl_lookup_hash can optionally give its caller a pointer to the module where the symbol was found. Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl. Spelling fixes in the Blackfin port, since Alex Oliva's original version of these patches used _dl_find_hash_mod as the name of the function rather than _dl_lookup_hash.

* Bernd Schmidt writes:Joakim Tjernlund2007-03-311-4/+1
| | | | | | | | | | Currently a static libdl.a doesn't run all the constructors or destructors of the libraries it loads. I can't see a good reason for that, and it does cause aborts in the destructors it does run for things like libgcc.so on the Blackfin. Fixed with the patch below - untested in mainline, but the equivalent has been in our Blackfin tree for a while now.

| | | | | | | | | Hi All, the attached patch completes my previous patch on statically linked application calling dlopen enabling the support for LD_DEBUG. Further it fixes the missing initialization of the _dl_library_path variable. This patch has been fully tested with the uClibc-nptl branch (sh4).
