2017-10-19sparc: Check bfd_link_executable for TLS checkH.J. Lu2-10/+20
Copied from x86, check bfd_link_executable, instead of bfd_link_pic, for TLS transition check. Not sure if it works correctly. All usages of bfd_link_pic should be audited. PR ld/22263 * elfxx-sparc.c (sparc_elf_tls_transition): Replace bfd_link_pic with !bfd_link_executable, !bfd_link_pic with bfd_link_executable for TLS check. (_bfd_sparc_elf_check_relocs): Likewise.

2017-10-17PR22307, Heap out of bounds read in _bfd_elf_parse_gnu_propertiesAlan Modra2-9/+15
When adding an unbounded increment to a pointer, you can't just check against the end of the buffer but also must check that overflow doesn't result in "negative" pointer movement. Pointer comparisons are signed. Better, check the increment against the space left using an unsigned comparison. PR 22307 * elf-properties.c (_bfd_elf_parse_gnu_properties): Compare datasz against size left rather than comparing pointers. Reorganise loop.

2017-10-16ELF: Call check_relocs after opening all inputsH.J. Lu42-3514/+83
For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32.

2017-10-12FT32: support for FT32B processor - part 1James Bowman5-0/+25
FT32B is a new FT32 family member. It has a code compression scheme, which requires the use of linker relaxations. The change is quite large, so submission is in several parts. Part 1 adds a 15-bit instruction field, and CPU-specific functions for the code compression that are used in binutils and GDB. bfd/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * elf32-ft32.c: Add HOWTO R_FT32_15. * reloc.c: Add BFD_RELOC_FT32_15. gas/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * config/tc-ft32.c (md_assemble): Replace FT32_FLD_K8 with K15.

2017-10-11ELF/BFD: Handle both variants of the 64-bit Linux core PRPSINFO noteMaciej W. Rozycki6-10/+106
Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>, and handle both variants of the 64-bit Linux core PRPSINFO note across all targets. The 64-bit Linux core PRPSINFO note matches the 64-bit kernel structure, defined as follows: (gdb) ptype struct elf_prpsinfo type = struct elf_prpsinfo { char pr_state; char pr_sname; char pr_zomb; char pr_nice; unsigned long pr_flag; __kernel_uid_t pr_uid; __kernel_gid_t pr_gid; pid_t pr_pid; pid_t pr_ppid; pid_t pr_pgrp; pid_t pr_sid; char pr_fname[16]; char pr_psargs[80]; } (gdb) where the individual data types of most members are the same across all 64-bit Linux ports, with the exception of `__kernel_uid_t' and `__kernel_gid_t'. These are defined in <asm-generic/posix_types.h> as 32-bit `unsigned int' by default, however overridden as 16-bit `unsigned short' in port-specific <asm/posix_types.h> for the SuperH target. The default is already handled, as from the commit referred. Add the other variant then and provide a backend flag to switch between the two cases possible, with the 32-bit one being the default and the 16-bit one explicitly selected. Set the flag in the SuperH target backend. This arrangement is analogous to how the 32-bit Linux core PRPSINFO note is handled. bfd/ * elf-bfd.h (elf_backend_data): Add `linux_prpsinfo64_ugid16' member. * elf-linux-core.h (elf_external_linux_prpsinfo64): Rename to...

2017-10-11ELF/BFD,GDB: Handle both variants of the 32-bit Linux core PRPSINFO noteMaciej W. Rozycki16-81/+135
Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>, and commit b3ac9c77560a ("Put more info in NT_PRPSINFO Linux notes"), <https://sourceware.org/ml/binutils/2013-02/msg00024.html>, and handle both variants of the 32-bit Linux core PRPSINFO note across all targets.

These are defined in <asm-generic/posix_types.h> as 32-bit `unsigned int' by default, however overridden as 16-bit `unsigned short' in port-specific <asm/posix_types.h> for a few targets, mostly earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k, MN10300/AM33, s390, SuperH, SPARC and i386. The default is the same as the PowerPC variant already handled, as from the commits referred. Make the special PowerPC case generic then, removing the GDB part, and provide a backend flag to switch between the two cases possible, with the 32-bit one being the default and the 16-bit one explicitly selected.

2017-10-11ELF/BFD: Fix padding in `elf_external_linux_prpsinfo64'Maciej W. Rozycki2-1/+6
Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>, and move the padding of the `elf_external_linux_prpsinfo64' structure to match the corresponding 64-bit Linux kernel `elf_prpsinfo' structure. The 64-bit kernel structure is defined as follows: (gdb) ptype struct elf_prpsinfo type = struct elf_prpsinfo { char pr_state; char pr_sname; char pr_zomb; char pr_nice; unsigned long pr_flag; __kernel_uid_t pr_uid; __kernel_gid_t pr_gid; pid_t pr_pid; pid_t pr_ppid; pid_t pr_pgrp; pid_t pr_sid; char pr_fname[16]; char pr_psargs[80]; } (gdb) print /x &((struct elf_prpsinfo *)0)->pr_nice $1 = 0x3 (gdb) print /x &((struct elf_prpsinfo *)0)->pr_flag $2 = 0x8 (gdb) print /x &((struct elf_prpsinfo *)0)->pr_uid $3 = 0x10 (gdb) print sizeof(((struct elf_prpsinfo *)0)->pr_flag) $4 = 8 (gdb) with implicit padding present before the `pr_flag' member, to correctly align it to a multiple of 8. Conversely `elf_external_linux_prpsinfo64' has padding after its `pr_flag' member: (top-gdb) ptype struct elf_external_linux_prpsinfo64 type = struct elf_external_linux_prpsinfo64 { char pr_state; char pr_sname; char pr_zomb; char pr_nice; char pr_flag[8]; char gap[4]; char pr_uid[4]; char pr_gid[4]; char pr_pid[4]; char pr_ppid[4]; char pr_pgrp[4]; char pr_sid[4]; char pr_fname[16]; char pr_psargs[80]; } (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_nice $1 = 0x3 (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_flag $2 = 0x4 (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_uid $3 = 0x10 (top-gdb) and consequently `pr_flag' is misplaced. Move `gap' ahead of `pr_flag' then. bfd/ * elf-linux-core.h (elf_external_linux_prpsinfo64): Move the `gap' member ahead of `pr_flag'.
