2020-05-07objcopy: Mention 'entry address' in descriptionAndrew Burgess2-4/+11
The ELF header contains a start address, which is also sometimes called the entry address. The 'objdump -x' output calls this field the 'start address', while readelf calls it 'entry point address'. The linker talks about setting the 'entry' point in its manual. I've always thought of this field as the 'entry address', and so when I recently wanted to know if objcopy could adjust this field I opened up the manual and searched for 'entry', which found no hits. I thought it would be useful (for people like me) if the description of 'set-start' and 'adjust-start' in the objcopy manual mentioned the word 'entry' to make it easier to find. binutils/ChangeLog: * doc/binutils.texi: Mention 'entry address' in the set-start and adjust-start options descriptions.

2020-04-23arc: Add support for ARC HS extra registers in core filesAnton Kolesov2-0/+12
When a coredump is generated, there are a few registers in ARC HS that are put under a special section, namely ".reg-v2". It is for backward compatibility reasons with older tools that we have decided not to extend the generic ".reg" section. This patch makes it possible to display the information better regarding that section. Compare the output of "readelf" without and with these changes: $ readelf -n core # without the patch ...

2020-04-20readelf: segfaults fuzzing multiple object filesAlan Modra2-15/+19
This patch is aimed at fixing a number of oss-fuzz segfaults that don't reproduce reliably with their current infrastructure, the problem being that one invocation of readelf is effectively being run on multiple object files. I believe that these segfaults could be reliably reproduced with just two fuzzed objects being presented to readelf, but those inputs are currently not identified by oss-fuzz. So there is some guesswork involved in this patch. The idea here is to clear stashed data such as symtab_shndx_list that is processed using section header info, at the same time that header info is cleared. * readelf.c (process_section_headers): Free dynamic symbols etc. earlier.

When reconstructing dynamic symbol table from the PT_DYNAMIC segment, compute dynamic symbol table size from hash table. For DT_HASH, the number of dynamic symbol table entries equals the number of chains. For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all symbols with STB_LOCAL binding before symbols with other bindings and all undefined symbols defined ones in dynamic symbol table, the highest symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol table index.

However, there's no point in pursuing this: Solaris does not support ifunc, as can be seen in <sys/elf.h>: /* * GNU/Linux specific symbol type not used by Solaris */ #define STT_GNU_IFUNC 10 and never will, given that it has symbol capabilities as solution to effectively the same problem: http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/ Therefore this patch disables ifunc testing on Solaris completely by removing Solaris from binutils/testsuite/lib/binutils-common.exp (supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is in the OS-specific range and conflicts with #define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */ While the comment suggests this might be relocatable without too much problems, the description of mbind (no formal spec AFAICS, just the comment in the binutils patch submission) strongly suggests that this isn't relevant to Solaris at all. Indirectly, clearing supports_gnu_osabi on Solaris disables supports_gnu_unique. Again, Solaris <sys/elf.h> has /* * GNU/Linux specific binding not used by Solaris */ #define STB_GNU_UNIQUE 10 so this seems the right thing to do. Afterwards, one can remove the explicit mentions of *-*-solaris2* in quite a number of (but not all) the ld-ifunc dump file notarget lists. There's one fallout, though: two gas tests now XPASS because they are xfail'ed for !supports_gnu_osabi: XPASS: mbind sections 12 XPASS: mbind section contents 16 XPASS: mbind sections 16 XPASS: mbind section contents 16 To fix that, I've changed #xfail: ![supports_gnu_osabi] to notarget.

2020-03-28Re: Adjust objcopy_testAlan Modra2-4/+9
Last patch didn't manage to xfail spu due to clear_xfail *-*-*elf*. Clearing *-*-*elf* dates back to a time when we had rather a lot more setup_xfail patterns, so limiting it to hppa*-*-*elf*. Also, mips-*-irix ought to have been mips-*-irix* and I'm having second thoughts about xfailing mips and hiding what looks like a problem: If the mips target is supposed to emit names for local section symbols and does so for objcopy, why isn't it doing the same for ld? Also, lots more mips targets would be subject to this test failing. So I'm backing out those xfails and leaving it to someone more knowledgeable about mips. * testsuite/binutils-all/objcopy.exp (objcopy_test): Only clear_xfail hppa*-*-*elf*. Revert mips xfails.
2020-03-28Adjust objcopy_testAlan Modra2-14/+28
xfails spu due to a note section getting a different vma, and some mips targets that give section symbols a name string. I added -p for the executable test in an attempt to fix all the pe target fails, but that doesn't preserve the date/time for some reason. * testsuite/binutils-all/objcopy.exp (objcopy_test): Move xfails from here to calls. Remove "m8*-*-*" entry. Don't xfail tic54x but do xfail spu, mipstx39 and mips-sgi-irix for the executable test. Pass "-p" to objcopy for the executable test.

This patch fixes a leak of qualified_name caused by 4c83662712 and a double free introduced by fd486f32d1. Not breaking out of the loop results in an error: "failed to seek to next archive header". That's slightly better than silently preventing the possibility of endless loops. * readelf.c (process_archive): Don't double free qualified_name.
