2018-09-10PR23611, objcopy is not removing executable relocatable sectionsAlan Modra1-6/+4
BFD handles ELF relocation sections in an executable differently to relocation sections in a relocatable object. For a relocatable object, BFD carries the relocations as data associated with the section to which they apply; The relocation section doesn't appear as a separate section. For an executable, dynamic relocation sections do appear as separate sections. This means that objcopy needs to use different strategies when dealing with relocations. When --remove-relocations was added to objcopy with commit d3e5f6c8f1e, objcopy lost the ability to remove dynamic relocation sections such as .rela.plt from executables using the option "--remove-section=.rela.plt". This patch reinstates that functionality. I thought it best to keep --remove-relocations as is, rather than extending to handle dynamic relocations as per the patch in the PR, because executables linked with --emit-relocs may have both dynamic and non-dynamic relocations. In that case --remove-relocataions=* is useful to remove all the non-dynamic relocations. PR binutils/23611 * objcopy.c (handle_remove_section_option): Consider .rela and .rel sections for stripping directly as well as attached to the associated section they relocate. * doc/binutils.texi (remove-relocations): Specify that this option removes non-dynamic relocation sections. * testsuite/binutils-all/objcopy.exp (objcopy_remove_relocations_from_executable): New test.

I am checking in the attached patch which updates the binutils support for version 3 binary annotation notes. (Version 3 adds an end address to the ranges covered by the notes, so that it is possible to detect gaps in the coverage).

2017-12-08Fix stripping relocs in a file with mergeable notes.Nick Clifton1-8/+19
A recent Fedora bug (1520805) exposed a problem with objcopy's reloc copying code, when a binary also contains mergeable notes. The note merging code would delete some relocs, but then the reloc copying code would try to put them back again, which did not work. So I am checking in the patch below to fix the problem. The patch also tweaks one of the binutils note merging tests so that it is skipped for the Sparc64 target, since this has funky relocs. binutils * objcopy.c (copy_relocations_in_section): Use the orelocations field of the input section, if it has been initialised. * testsuite/binutils-all/note-2-64.d: Skip test on Sparc64. bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.

2017-02-17bfd: Rename Chunk and S3ForcedPedro Alves1-6/+6
The direct references in objcopy kind of look like a hack to me, so I'm calling these symbols internal too. Certainly they aren't named and documented as a public BFD symbol today anyway. So ... give these bfd-internal symbols with external linkage a _bfd_ prefix to avoid collisions in the global symbol namespace. While at it, give them names that more closely match the corresponding option name that toggles them. Also while at it, fix a few related comment typos. gdb/ChangeLog: 2017-02-17 Pedro Alves <palves@redhat.com> * srec.c (Chunk): Rename to ... (_bfd_srec_len): ... this. (S3Forced): Rename to ... (_bfd_srec_forceS3): ... this. * objcopy.c: Adjust all references.

2016-07-14objcopy/strip: Add option --remove-relocations=SECTIONPATTERNAndrew Burgess1-5/+58
The objcopy and strip tools make use of the bfd library to manipulate the state of the input file (to produce an output file). Within the input file (for ELF at least), relocations are held within a section, and so, if the user wanted to remove the relocations, but keep the section to which the relocations would have been applied, it is tempting to think that specifying the name of a relocation section to objcopy's --remove-section option might do what you want, for example: objcopy --remove-section=.rela.text input.elf output.elf However, this does not work. The reason is that when the input file is loaded, relocations are not managed as sections, but are, instead, loaded as data associated with the section to which the relocations would be applied. In our example above the relocations in '.rela.text' are held as data on the section '.text' once 'input.elf' is loaded. One task that objcopy and strip do is copy the relocations from the input file to the output file if the section is also being copied from the input file to the output file. This commit adds a new command line option for objcopy and strip, --remove-relocations, which can be used to remove the relocations, while keeping the section that the relocations would have been applied to, for example: objcopy --remove-relocations=.text input.elf output.elf in this case the section '.text' will appear in both 'input.elf' and 'output.elf', but any relocations in 'input.elf' that apply to '.text' will not be present in 'output.elf'. I have also added a special case to the handling of --remove-section that spots if a user tries to remove a relocation section (currently this is done by spotting the '.rela.' or '.rel.' prefix) and forwards the request to --remove-relocations. As with --remove-section and --only-section the --remove-relocations option supports the '!' prefix on the section-patterns it takes to allow for sections to be specifically not matched. There are tests for all the new functionality. binutils/ChangeLog: * doc/binutils.texi (objcopy): Document 'remove-relocations'.

2016-07-14objcopy/strip: Allow section patterns starting with '!'.Andrew Burgess1-11/+28
For symbol matching, prefixing a pattern with '!' will indicate a non-matching pattern, however, this is not the case for section patterns. As a result it is not possible to say "apply this action to all sections except ...". With this commit the objcopy and strip tools now support '!' prefix for section patterns, so we can say: objcopy --remove-section="*" --remove-section="!.text*" Which will remove all sections, except those matching the pattern '.text*'. binutils/ChangeLog: * objcopy.c (find_section_list): Handle section patterns starting with '!' being a non-matching pattern. * doc/binutils.texi (objcopy): Give example of using '!' with --remove-section and --only-section.

2016-06-24MIPS objcopy --rename-section fixAlan Modra1-16/+17
Some MIPS targets use a named section symbol rather than a symbol with no name as is used with most ELF targets. When renaming sections, the named section symbol needs to be renamed too. Rather than fix this bug, I'd originally intended to just correct the xfail added recently for update-1.o vs update4.o in update-section.exp, using the same set of targets for the localize-hidden-1 mips xfail. I'd extracted that target test into a new function, is_bad_symtab. It turns out to be useful in readelf.exp too. bfd/ * config.bfd: Delete mips vxworks patterns matched earlier. Combine mips*-*-none with mips*-*-elf*. binutils/ * objcopy.c (find_section_rename): Forward declare. Remove ibfd and sec_ptr param. Add old_name param. Allow for NULL returned_flags.

A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default.
