2016-12-29link_hash_copy_indirect and symbol flagsAlan Modra11-47/+63
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among other things, modified _bfd_elf_link_hash_copy_indirect to not copy ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt and pointer_equality_needed when setting up an indirect non-versioned symbol pointing to a non-default versioned symbol. I didn't notice at the time, but the pr18720 testcase fails on hppa-linux with "internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933 in elf32_hppa_relocate_section". Now hppa-linux creates entries in the plt even for local functions, if they are referenced using plabel (function pointer) relocations. So needs_plt is set for foo when processing pr18720a.o. When the aliases in pr28720b.o are processed, we get an indirection from foo to foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol that is used after that point, no plt entry is made for foo and we bomb when relocating the plabel. As shown by the hppa-linux scenario, needs_plt should be copied even for non-default versioned symbols. I believe all of the others ought to be copied too, with the exception of ref_dynamic. Not copying ref_dynamic is right because if a shared lib references "foo" it should not be satisfied by any non-default version "foo@FOO". * elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit copying one flag, ref_dynamic, when versioned_hidden. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise. * elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Use same logic for copying weakdef flags.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra29-154/+521
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.

2016-12-21bfd: aarch64: fix word and arrdess size declaration in ilp32 modeYury Norov2-4/+11
ILP32 has 32-bit word and address, but currently they declared as 64-bit in bfd_aarch64_arch_ilp32, which breaks further logic of bfd. This patch fixes it. Glibc testsuite build with patched binutils shows that next tests stop to fail: iconvdata/mtrace-tst-loading iconvdata/tst-loading iconvdata/tst-tables localedata/mtrace-tst-leaks localedata/tst-leaks posix/tst-getaddrinfo4 posix/tst-getaddrinfo5 posix/tst-regex2

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman2-2/+7
We've decided to standardize on two flags for RISC-V: "-march" sets the target architecture (which determines which instructions can be generated), and "-mabi" sets the target ABI. We needed to rework this because the old flag set didn't support soft-float or single-float ABIs, and didn't support an x32-style ABI on RISC-V. Additionally, we've changed the behavior of the -march flag: it's now a lot stricter and only parses things we can actually understand. Additionally, it's now lowercase-only: the rationale is that while the RISC-V ISA manual specifies that ISA strings are case-insensitive, in Linux-land things are usually case-sensitive. Since this flag can be used to determine library paths, we didn't want to bake some case-insensitivity in there that would case trouble later. This patch implements these two new flags and removes the old flags that could conflict with these. There wasn't a RISC-V release before, so we want to just support a clean flag set. include/ * elf/riscv.h (EF_RISCV_SOFT_FLOAT): Don't define. (EF_RISCV_FLOAT_ABI, EF_RISCV_FLOAT_ABI_SOFT): Define.
