2021-01-07ELF: Don't generate unused section symbolsH.J. Lu10-10/+144
For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3. Remove unused section symbols from expected assembler and linker outputs. bfd/ PR 27109 * aix386-core.c (core_aix386_vec): Initialize keep_unused_section_symbol to TARGET_KEEP_UNUSED_SECTION_SYMBOLS. * aout-target.h (MY (vec)): Likewise. * binary.c (binary_vec): Likewise. * cisco-core.c (core_cisco_be_vec): Likewise.

(print_vms_time): Catch 64-bit overflow when converting from vms time to posix time. Don't segfault if gmtime returns NULL.

2020-12-07binutils: Make smart_rename safe tooSiddhesh Poyarekar6-42/+148
smart_rename is capable of handling symlinks by copying and it also tries to preserve ownership and permissions of files when they're overwritten during the rename. This is useful in objcopy where the file properties need to be preserved. However because smart_rename does this using file names, it leaves a race window between renames and permission fixes. This change removes this race window by using file descriptors from the original BFDs that were used to manipulate these files wherever possible. The file that is to be renamed is also passed as a file descriptor so that we use fchown/fchmod on the file descriptor, thus making sure that we only modify the file we have opened to write. Further, in case the file is to be overwritten (as is the case in ar or objcopy), the permissions that need to be restored are taken from the file descriptor that was opened for input so that integrity of the file status is maintained all the way through to the rename. binutils/ * rename.c * ar.c (write_archive) [!defined (_WIN32) || defined (__CYGWIN32__)]: Initialize TARGET_STAT and OFD to pass to SMART_RENAME. * arsup.c (ar_save) [defined (_WIN32) || defined (__CYGWIN32__)]: Likewise. * bucomm.h (smart_rename): Add new arguments to declaration. * objcopy.c (strip_main)[defined (_WIN32) || defined (__CYGWIN32__)]: Initialize COPYFD and pass to SMART_RENAME. (copy_main) [defined (_WIN32) || defined (__CYGWIN32__)]: Likewise. * rename.c (try_preserve_permissions): New function. (smart_rename): Use it and add new arguments.
2020-12-07objcopy: Get input file stat after BFD openSiddhesh Poyarekar2-16/+16
Get file state from the descriptor opened by copy_file for the input BFD. This ensures continuity in the view of the input file through the descriptor. At the moment it is only to preserve timestamps recorded at the point that we opened the file for input but in the next patch this state will also be used to preserve ownership and permissions wherever applicable. binutils/ * objcopy.c (copy_file): New argument IN_STAT. Return stat of ibfd through it. (strip_main): Remove redundant stat calls. adjust copy_file calls. (copy_main): Likewise.
2020-12-07binutils: Use file descriptors from make_tempnameSiddhesh Poyarekar5-14/+50
The purpose of creating a temporary file securely using mkstemp is defeated if it is closed in make_tempname and reopened later for use; it is as good as using mktemp. Get the file descriptor instead and then use it to create the BFD object. bfd/ * opncls.c (bfd_fdopenw): New function. * bfd-in2.h: Regenerate. binutils/ * bucomm.c (make_tempname): Add argument to return file descriptor. * bucomm.h (make_tempname): Likewise. * ar.c: Include libbfd.h. (write_archive): Adjust for change in make_tempname. Call bfd_fdopenw instead of bfd_openw. * objcopy.c: Include libbfd.h. (copy_file): New argument OFD. Use bfd_fdopenw instead of bfd_openw.

2020-12-04asan: readelf: memory leaksAlan Modra3-40/+65
This tidies some code used by readelf, hopefully fixing some intermittent oss-fuzz bug reports that likely could only be reproduced by feeding readelf two or more object files on the command line. The second and subsequent file may see non-zero state in .bss variables, and non-initial values in .data variables. This patch fixes some of those, and moves some .data variables to .rodata. * dwarf.c (frame_display_row): Do without static variable "sloc". (cu_tu_indexes_read): Move to file scope. (free_debug_memory): Reset it here, along with level_type_signed. Free and clear a number of other static variables. * readelf.c (arm_attr_public_tag <table>): Constify, updating.. (arm_attr_tag_*): ..all these uses. (process_mips_specific): Free "rels" on error path.

2020-11-27ELF: Support .noinit and .persistent sectionsJozef Lawrynowicz2-0/+44
The ".persistent" section is for data that should be initialized during load, but not during application reset. The ".noinit" section is for data that should not be initialized during load or application reset. Targets utilizing the elf.sc linker script template can define HAVE_{NOINIT,PERSISTENT}=yes to include the .noinit or .persistent output sections in the generated linker script. Targets with existing support for .noinit did not handle unique .noinit.* and .gnu.linkonce.n.* sections the .noinit output section, this patch also fixes that. bfd/ChangeLog: * elf.c (special_sections_g): Add .gnu.linkonce.n and .gnu.linkonce.p.
