* Fix relocation to look for symbols in local groupDmitriy Ivanov2014-10-313-79/+124
| | | | | | | | | | | | | | | | The local group is a sequence of libraries in default (breadth-first) order. It allows RTLD_LOCALLY loaded library to correctly relocate symbols within its group (see test-cases). Local group lookup is performed after main executable and ld_preloads.

* Add IFUNC support for arm64 and IRELATIVE relocDmitriy Ivanov2014-10-013-127/+59
| | | | | | | | | | | | | | | | | | There are number of changes in the way IFUNC related relocations are done: 1. IRELATIVE relocations are now supported for x86/x86_64 and arm64. 2. IFUNC relocations are now relying on static linker to generate them in correct order - this removes necessety of additional relocation pass for ifuncs. 3. Related to 2: rela?.dyn relocations are preformed before .plt ones. 4. Ifunc are resolved on symbol lookup this approach allowed to avoid mprotect(PROT_WRITE) call on r-x program segments.

* Replace snprintf calls in linker.Christopher Ferris2014-08-272-3/+17
| | | | | | | | | | | | | | | | When enabling debug malloc, the snprintf calls in the linker fails to update the buffer. The problem is that snprintf makes a call to pthread_getspecific that returns a valid pointer, but the data it points to is zero. This should never happen and causes the snprintf to stop and do nothing. Temporarily replace snprintf with a different implementation to work around this issue.
