2018-07-18S/390: Improve partial relro support for 64 bitAndreas Krebbel1-0/+81
Currently on S/390 the .got.plt always comes first which prevents the GNU_RELRO segment from being extended across the non-plt GOT entries. Just swapping both unfortunately is not that simple since our ABI requires the _GLOBAL_OFFSET_TABLE_ symbol to point to the very beginning of the entire GOT. Of the 3 magic GOT entries the first is accessed via got pointer while second and third are being accessed via DT_PLTGOT. In order to keep them together we make DT_PLTGOT to point to the .got instead of .got.plt. However, this violates an assumption in the dynamic linker prelink undo code about the GOTPLT entries starting at DT_PLTGOT + 3. We got rid of this requirement with a Glibc patch already in version 2.24: https://sourceware.org/ml/libc-alpha/2016-06/msg01302.html So the S/390 relro GOT layout will look like this with this patch: +----------------------------------+ |got[0]: DYNAMIC | <--- _GLOBAL_OFFSET_TABLE_ == DT_PLTGOT .got |got[1]: link_map parm | |got[2]: &_dl_runtime_resolve | +----------------------------------+ | | non-plt GOT entries | | | | +----------------------------------+ | | <--- .gotplt, PLT GOT entries | | | | | | +----------------------------------+ The patch detects the current layout in size_dynamic_section in order to deal also with linker scripts not generated by this ld version. With partial relro enabled we pick a linker script where .got and .got.plt are swapped which then triggers the rest of the logic. ld/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> * emulparams/elf64_s390.sh: Define GENERATE_RELRO_SCRIPT and SEPARATE_GOTPLT. * testsuite/ld-s390/gotreloc_64-relro-1.dd: New test. * testsuite/ld-s390/gotreloc_64-norelro-1.dd: Renamed from ... * testsuite/ld-s390/gotreloc_64-1.dd: ... this. * testsuite/ld-s390/s390.exp: Split the GOT testcase into two. bfd/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> * elf-s390-common.c (s390_gotplt_after_got_p): New function.

2016-10-07Pass link_info to _bfd_merge_private_bfd_dataAlan Modra1-2/+3
Most BFD linker functions take a bfd_link_info param, which reinforces the fact that they are linker functions and allow access to linker callbacks, eg. einfo for printing errors.

2015-08-18Add output_type to bfd_link_infoH.J. Lu1-7/+10
The "shared" field in bfd_link_info is set for both DSO and and PIE. There are separate fields for executable and relocatable outputs. This patch adds an "output_type" field: enum output_type { type_unknown = 0, type_executable, type_dll, type_relocatable }; and a "pic" field to bfd_link_info to replace shared, executable and relocatable fields so that we can use the "output_type" field to check for output type and the "pic" field check if output is PIC. Macros, bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic and bfd_link_pie, are provided to check for output features. bfd/ * bfd/aoutx.h: Replace shared, executable, relocatable and pie fields with bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic and bfd_link_pie. * bfd/bout.c: Likewise. * bfd/coff-alpha.c: Likewise. * bfd/coff-arm.c: Likewise. * bfd/coff-i386.c: Likewise. * bfd/coff-i960.c: Likewise. * bfd/coff-m68k.c: Likewise. * bfd/coff-mcore.c: Likewise. * bfd/coff-mips.c: Likewise. * bfd/coff-ppc.c: Likewise. * bfd/coff-rs6000.c: Likewise. * bfd/coff-sh.c: Likewise. * bfd/coff-tic80.c: Likewise. * bfd/coff-x86_64.c: Likewise. * bfd/coff64-rs6000.c: Likewise. * bfd/coffgen.c: Likewise. * bfd/cofflink.c: Likewise. * bfd/ecoff.c: Likewise. * bfd/ecofflink.c: Likewise. * bfd/elf-bfd.h: Likewise. * bfd/elf-eh-frame.c: Likewise. * bfd/elf-ifunc.c: Likewise. * bfd/elf-m10200.c: Likewise. * bfd/elf-m10300.c: Likewise. * bfd/elf-s390-common.c: Likewise. * bfd/elf-vxworks.c: Likewise. * bfd/elf.c: Likewise. * bfd/elf32-arm.c: Likewise. * bfd/elf32-avr.c: Likewise. * bfd/elf32-bfin.c: Likewise. * bfd/elf32-cr16.c: Likewise. * bfd/elf32-cr16c.c: Likewise. * bfd/elf32-cris.c: Likewise. * bfd/elf32-crx.c: Likewise. * bfd/elf32-d10v.c: Likewise. * bfd/elf32-dlx.c: Likewise. * bfd/elf32-epiphany.c: Likewise. * bfd/elf32-fr30.c: Likewise. * bfd/elf32-frv.c: Likewise. * bfd/elf32-ft32.c: Likewise. * bfd/elf32-h8300.c: Likewise. * bfd/elf32-hppa.c: Likewise. * bfd/elf32-i370.c: Likewise. * bfd/elf32-i386.c: Likewise. * bfd/elf32-i860.c: Likewise. * bfd/elf32-ip2k.c: Likewise. * bfd/elf32-iq2000.c: Likewise. * bfd/elf32-lm32.c: Likewise. * bfd/elf32-m32c.c: Likewise. * bfd/elf32-m32r.c: Likewise. * bfd/elf32-m68hc11.c: Likewise. * bfd/elf32-m68hc1x.c: Likewise. * bfd/elf32-m68k.c: Likewise. * bfd/elf32-mcore.c: Likewise. * bfd/elf32-mep.c: Likewise. * bfd/elf32-metag.c: Likewise. * bfd/elf32-microblaze.c: Likewise. * bfd/elf32-moxie.c: Likewise. * bfd/elf32-msp430.c: Likewise. * bfd/elf32-mt.c: Likewise. * bfd/elf32-nds32.c: Likewise. * bfd/elf32-nios2.c: Likewise. * bfd/elf32-or1k.c: Likewise. * bfd/elf32-ppc.c: Likewise. * bfd/elf32-rl78.c: Likewise. * bfd/elf32-rx.c: Likewise. * bfd/elf32-s390.c: Likewise. * bfd/elf32-score.c: Likewise. * bfd/elf32-score7.c: Likewise. * bfd/elf32-sh-symbian.c: Likewise. * bfd/elf32-sh.c: Likewise. * bfd/elf32-sh64.c: Likewise. * bfd/elf32-spu.c: Likewise. * bfd/elf32-tic6x.c: Likewise. * bfd/elf32-tilepro.c: Likewise. * bfd/elf32-v850.c: Likewise. * bfd/elf32-vax.c: Likewise. * bfd/elf32-visium.c: Likewise. * bfd/elf32-xc16x.c: Likewise. * bfd/elf32-xstormy16.c: Likewise. * bfd/elf32-xtensa.c: Likewise. * bfd/elf64-alpha.c: Likewise. * bfd/elf64-hppa.c: Likewise. * bfd/elf64-ia64-vms.c: Likewise. * bfd/elf64-mmix.c: Likewise. * bfd/elf64-ppc.c: Likewise. * bfd/elf64-s390.c: Likewise. * bfd/elf64-sh64.c: Likewise. * bfd/elf64-x86-64.c: Likewise. * bfd/elflink.c: Likewise. * bfd/elfnn-aarch64.c: Likewise. * bfd/elfnn-ia64.c: Likewise. * bfd/elfxx-mips.c: Likewise. * bfd/elfxx-sparc.c: Likewise. * bfd/elfxx-tilegx.c: Likewise. * bfd/i386linux.c: Likewise. * bfd/linker.c: Likewise. * bfd/m68klinux.c: Likewise. * bfd/pdp11.c: Likewise. * bfd/pe-mips.c: Likewise. * bfd/peXXigen.c: Likewise. * bfd/reloc.c: Likewise. * bfd/reloc16.c: Likewise. * bfd/sparclinux.c: Likewise. * bfd/sunos.c: Likewise. * bfd/vms-alpha.c: Likewise. * bfd/xcofflink.c: Likewise. include/ * include/bfdlink.h (output_type): New enum.

2015-08-12Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbolsH.J. Lu1-1/+1
Since the backend elf_add_symbol_hook isn't called on local symbols, the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols. This patch changes the x86 backends to set has_gnu_symbols if there are relocations against IFUNC symbols. Other backends with IFUNC support may need a similar change.

2015-03-14S/390: Disable relocation sort against code sections.Andreas Krebbel1-0/+12
When downgrading from GD to IE model we rewrite the call to __tls_get_offset to a 64 bit load instruction. This relies on the fact that the additional relocation for the call target has already been executed when doing the rewrite. f1018: e3 20 d0 00 00 04 lg %r2,0(%r13) f101e: c0 e5 00 00 00 00 brasl %r14,f101e <__res_init+0x1e> f101e: R_390_TLS_GDCALL __libc_resp f1020: R_390_PLT32DBL __tls_get_offset+0x2 0000000f1020 39f6c00000014 R_390_PLT32DBL 0000000000000000 __tls_get_offset + 2 0000000f101e 3afb700000026 R_390_TLS_GDCALL 0000000000000008 __libc_resp + 0 Due to the reloc sorting the order changed an the PLT32DBL reloc is executed after the rewrite and overwrites part of the load instruction with garbage. bfd/ 2015-03-14 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * elf-s390-common.c (elf_s390_elf_sort_relocs_p): Don't sort relocs against code sections. * elf32-s390.c: Define elf_backend_sort_relocs_p. * elf64-s390.c: Likewise.
