* dynrelro section for read-only dynamic symbols copied into executableAlan Modra2016-12-269-32/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variables defined in shared libraries are copied into an executable's .bss section when code in the executable is non-PIC and thus would require dynamic text relocations to access the variable directly in the shared library. Recent x86 toolchains also copy variables into the executable to gain a small speed improvement. The problem is that if the variable was originally read-only, the copy in .bss is writable, potentially opening a security hole. This patch cures that problem by putting the copy in a section that becomes read-only after ld.so relocation, provided -z relro is in force. The patch also fixes a microblaze linker segfault on attempting to use dynamic bss variables. bfd/ PR ld/20995 * elf-bfd.h (struct elf_link_hash_table): Add sdynrelro and sreldynrelro.

* ld: aarch64: fix TLS relaxation where TCB_SIZE is usedYury Norov2016-12-144-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for ilp32. During relaxation, ld goes to do a replace: bl __tls_get_addr => add R0, R0, TCB_SIZE But actual implementation is: bfd_putl32 (0x91004000, contents + rel->r_offset + 4); Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32. The possible fix for it is: bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4); But ilp32 also needs w-registers, so it's simpler to put proper instruction in #if/#else condition. There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new tests added for ilp32 mode to test it.
