2014-10-23Fix relocation to look for symbols in local groupDmitriy Ivanov
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. Bug: 2643900 Bug: 15432753 Change-Id: I9bb013b46d17dbb5cbdfb8fef26f552748385541

This reverts commit 8f61d991831f0ea515fa50a5c38dbbcfbab0dd28 Despite the fact that static linker does all the work while linking -Bsymbolic executables, according to the SCO doc following DT_SYMBOLIC and DF_SYMBOLIC flags is still a requirement for the dynamic linker as well.

From the elf-spec: "Symbolically bound shared objects are identified by the .dynamic entry DT_SYMBOLIC. This tag is informational only; the runtime linker processes symbol lookups from these objects in the same manner as any other object." Change-Id: I4aae0e502ed9fac096fbf076f4d6b2e055d784f6

2014-09-11Add IFUNC support for arm64 and IRELATIVE relocDmitriy Ivanov
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.

2014-09-01Look into ld_preloads before current libraryDmitriy Ivanov
Change lookup order during relocation so that ld_preloads always precede caller (unless caller is main executable). Asan needs this change in order to intercept libc->libc calls.

2014-08-27Replace snprintf calls in linker.Christopher Ferris
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. Bug: 16874447 Bug: 17302493 (cherry pick from commit 172955a4e30b88ce8239a7ef426b4e8903e9923c) Change-Id: Idca9d417978403d61debfd0434aaa82fd770f33b
