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. The 32-bit Linux core PRPSINFO note matches the 32-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 32-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 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. Set the flag in the target backends affected. bfd/ * elf-bfd.h (elf_backend_data): Add `linux_prpsinfo32_ugid16' member.

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'.

2017-10-10x86: Set GOT refcount to 1H.J. Lu3-6/+12
Since x86 check_relocs is called after opening all inputs and garbage collection, they never see the removed sections. There is no need for incrementing GOT refcount. But since PLT refcount is also used in /* Don't create the PLT entry if there are only function pointer relocations which can be resolved at run-time. */ else if (htab->elf.dynamic_sections_created && (h->plt.refcount > eh->func_pointer_refcount || eh->plt_got.refcount > 0)) { we must increment it. * elf32-i386.c (elf_i386_check_relocs): Set GOT refcount to 1 instead of incrementing it. * elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.

2017-10-05PR21167, relocation sections not included in groupsAlan Modra2-18/+39
This fixes a wart I've known about for years, but haven't done anything about because BFD treats relocation sections as an adjunct to the section they relocate. SHF_GROUP on the section thus implicitly applies to its relocation section(s), but it is an error that the reloc sections aren't part of the group. Like many patches to gas, this wasn't as straightforward as it could be due to a number of backends, i386, cr16 and others, removing relocs in tc_get_reloc rather than marking them as "done" earlier in md_apply_reloc. So it isn't possible for the group support to reliably detect the presence of relocs by looking at fixups earlier than write_relocs. However the group support needs to create signature symbols, and that must be done before the symbol table is frozen, before write_relocs. So split off the group sizing from elf_adjust_symtab and put it in elf_frob_file_after_relocs. bfd/ PR 21167 * elf.c (_bfd_elf_setup_sections): Don't trim reloc sections from groups.
