* AArch64: When DF_BIND_NOW don't use TLSDESC GOT value.gentoo/binutils-2.32-2Tamar Christina2019-04-185-4/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using DF_BIND_NOW on AArch64 we don't reserve the GOT slot for a TLSDESC, but we still emitted DT_TLSDESC_GOT and DT_TLSDESC_PLT. This caused random memory corruption as the "special" value of (bfd_vma)-1 would be set for dt_tlsdesc_got. Since we don't have a value of dt_tlsdesc_got I also don't emit DT_TLSDESC_PLT now becuase it would point to an incomplete PLT. To be able to write the PLT entry DT_TLSDESC_GOT is needed and since we don't have one we can't write the PLT entry either. It is my understanding that GLIBC doesn't need these two entries when not lazy loading. Conversely AArch32 does not reserve neither the GOT not the PLT slot when doing DF_BIND_NOW. AArch32 does not need these checks because these values are initialized to 0 and so the if (...) checks don't pass, but on AArch64 these are initialized to (bfd_vma)-1 and thus we need some extra checks. bfd/ChangeLog: PR ld/24302 * elfnn-aarch64.c (elfNN_aarch64_size_dynamic_sections): Don't emit DT_TLSDESC_GOT and DT_TLSDESC_PLT when DF_BIND_NOW.

* AArch64: Fix disassembler bug with out-of-order sectionsTamar Christina2019-04-1823-158/+640
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AArch64 disassembler has an optimization that it uses to reduce the amount it has to search for mapping symbols during disassembly. This optimization assumes that sections are listed in the section header in monotonic increasing VMAs. However this is not a requirement for the ELF specification. Because of this when such "out of order" sections occur the disassembler would pick the wrong mapping symbol to disassemble the section with. This fixes it by explicitly passing along the stop offset for the current disassembly glob and when this changes compared to the previous one we've seen the optimization won't be performed. In effect this restarts the search from a well defined starting point. Usually the symbol's address. The existing stop_vma can't be used for this as it is allowed to be unset and setting this unconditionally would change the semantics of this field. binutils/ChangeLog: * objdump.c (disassemble_bytes): Pass stop_offset. * testsuite/binutils-all/aarch64/out-of-order.T: New test. * testsuite/binutils-all/aarch64/out-of-order.d: New test. * testsuite/binutils-all/aarch64/out-of-order.s: New test. include/ChangeLog: * dis-asm.h (struct disassemble_info): Add stop_offset. opcodes/ChangeLog: * aarch64-dis.c (last_stop_offset): New.

| | | | | | | | | | | | | | | | | | | | | | | Recent gcc commit b4371b277f1e ("[ARC] Enable init_array support") inhibits DT_"INIT,FINI} in favor of DT_{INIT,FINI}ARRAY.

* PR24355, segmentation fault in function called from ppc_finish_symbolsAlan Modra2019-04-182-6/+9
| | | | | | | | | | | | | | | | | | | | | | | This one looks to be a bug going back to 2009, git commit e054468f6c "STT_GNU_IFUNC support for PowerPC". That bug was carried over with git commit 49c09209d0 "Rearrange PLT reloc output on powerpc". If the refcount for an ifunc local sym plt entry was zero, ppc_elf_size_dynamic_sections would correctly set plt.offset to -1 but leave glink_offset uninitialized. That leads to occasional segfaults (which can be made solid with MALLOC_PERTURB_=1 when using glibc). So, guard the write_glink_stub call with plt.offset != -1. Also, remove the totally ineffective attempt at writing multiple-use glink stubs only once.

* Gentoo: opcodes: link against libbfd.la for rpath depsMike Frysinger2019-02-162-2/+2
| | | | | | | | | | | | | The reason opcodes doesn't link against libbfd.la is to workaround a libtool bug where it uses installed -L paths ahead of DESTDIR paths. The downside is that the library itself lacks rpath tags to find the right version of libbfd.so. Since Gentoo has patched the libtool bug for a while, we don't need the workaround. Use the .la file so we get the rpath tags. URL: https://bugs.gentoo.org/563934 (cherry picked from commit 662586237b0b00ee881e79b56f6234ff36e8bfe6)
* Gentoo: libiberty: install PIC version of libiberty.aMike Frysinger2019-02-161-0/+1
| | | | | | | | | | | | | This will install a PIC version of libiberty.a by overwriting the non-PIC version of libiberty.a while compiling. We do this because there is no shared version of libiberty for random apps to link against which means if someone wants to use this in a shared library or PIE, they're out of luck. It's arguable whether people should be able to use this in a shared lib, but usage in PIE should be fine. You could argue that this penalizes the non-PIE users, but the counter point is that people using this library in general are fairly low, and we'd rather have things work for all of them.

* Gentoo: gold/ld: add support for poisoned system directoriesMike Frysinger2019-02-1611-0/+146
| | | | | | | | | | | | | | | | | | | | | | This is based on the old CodeSourcery patch written by Joseph Myers to add support to the link for detecting & rejecting bad -L paths when using a cross-compiler. The differences here: * The command line flags are always available. * We can turn on & off the warning via the command line. * The configure option controls the default warning behavior. * Add support for gold. It is not currently upstream, nor has it been submitted at all. There are no plans to do so currently either.

| | | | | | | | | textrels are bad for forcing copy-on-write (this affects everyone), and for security/runtime code generation, this affects security ppl. But in either case, it doesn't matter who needs textrels, it's the very fact that they're needed at all. (cherry picked from commit cd6411ad57aab78686f67cbbc1ed70ee810ad335)

* Arm: Backport hlt to all architectures.Tamar Christina2019-02-077-2/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The software trap instruction HLT that was introduced in Armv8-a is used as the semihosting trap instruction in AArch64. In order to allow systems configured to run AArch64 code to also run AArch32 with semihosting it was decided that AArch32 should also use HLT in the case of the "mixed mode" environment. This requires that HLT also be backported to all earlier architectures. The instruction is in the undefined encoding space earlier architectures but must trigger a semihosting trap [3]. The Arm Architectural Reference Manual [1] doesn't explicitly mention this however this is an explicit requirement in the Semihosting-v2 protocol [2].
