2019-09-23PR25018, readelf crash on 32bitsAlan Modra2-4/+13
Pointer comparisons after adding an offset just don't work to catch overflow when the offset is a larger type than the pointer. PR 25018 * dwarf.c (get_type_signedness): Delete ineffective pointer comparison check. Properly range check uvalue offset on recursive call.

2019-09-19AArch64: Fix objdump testsTamar Christina2-2/+6
The newly added objdump -S tests check for source line mapping of a static variable. But the test doesn't dump any data sections so this should never pass. This changes the test to dump all sections so the source mapping can be found. binutils/ChangeLog: * testsuite/binutils-all/objdump.exp (objdump -S): Update testcases.
2019-09-19bfd_section_* macrosAlan Modra20-145/+149
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-09-18binutils: doc: make `make clean` clean more thingsSimon Marchi3-6/+9
There is a bunch of things left over after a `make clean` in the doc directory. This patch changes the Makefile so that everything built by make is cleaned: - man pages (the man_MANS variable) - cxxfilt.man - binutils.info I am not sure why the last one was in MAINTAINERCLEANFILES. It's generated from binutils.texi using makeinfo, and it's not particularly long to build, so I don't see why it shouldn't be cleaned like the other files. Note: with my automake 1,15.1 (built from source), I get a spurious diff in Makefile.in, where the runstatedir = @runstatedir@ line gets removed. I am not sure why, but I haven't included it. binutils/ChangeLog: * doc/Makefile.am (MOSTLYCLEANFILES): Clean all man pages, cxxfilt.man and binutils.info. (MAINTAINERCLEANFILES): Remove. * doc/Makefile.in: Re-generate.

2019-09-18binutils: doc: remove stale things from MakefileSimon Marchi3-28/+13
The `install-data-local: install-info` part: the comment refers to when the Makefile had the cygnus option. It no longer uses that, so the info file should get installed without that rule. I verified that `make install` still installed $(prefix)/share/info/binutils.info. The `DISTCLEANFILES` part: the comment talks about Automake 1.9, we are using 1.15.1, which doesn't appear to have this problem. binutils.info is built fine without this snippet. Note: with my automake 1,15.1 (built from source), I get a spurious diff in Makefile.in, where the runstatedir = @runstatedir@ line gets removed. I am not sure why, but I haven't included it. binutils/ChangeLog: * doc/Makefile.am (install-data-loca): Remove target. (DISTCLEANFILES): Remove variable. * doc/Makefile.in: Re-generate.
2019-09-18Re-generate many configure and Makefile.in filesSimon Marchi4-24/+14
I get some spurious changes when running autoconf/automake for various projects in the tree. This is likely because they were generated using distro-patched tools last time. I ran `autoreconf -f` in the various automake projects of the binutils-gdb tree, and this is the result. The tools I am using have been compiled from source, from the upstream release. bfd/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. binutils/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. gas/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. * doc/Makefile.in: Re-generate. gold/ChangeLog: * testsuite/Makefile.in: Re-generate. gprof/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. ld/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate. opcodes/ChangeLog: * Makefile.in: Re-generate. * configure: Re-generate.

2019-08-09Add support for a MIPS specific .MIPS.xhash section.Mihailo Stojanovic2-4/+58
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

When printing unknown note types, readelf prints the raw description section byte-by-byte. However, it does not mask appropriately, e.g. it prints the byte 'ba' as 'ffffffba'. * readelf.c (process_note): Mask unknown description data bytes.
2019-08-08Integer overflows in readelf get_dataAlan Modra2-8/+10
I noticed the test for overflow of amt = size * nmemb in get_data wasn't effective. An obvious example of nmemb = 3 and size = half max value overflows but doesn't result in amt < nmemb. This patch fixes this problem and reports a size truncation or overflow rather than out of memory in more cases. * readelf.c (get_data): Improve overflow checks.

2019-07-23SHF_GNU_MBIND requires ELFOSABI_GNUAlan Modra2-43/+66
When SHF_GNU_MBIND was added in the SHF_LOOS to SHF_HIOS range, it should have required ELFOSABI_GNU since these flags are already in use by other OSes. HPUX SHF_HP_TLS in fact has the same value. That means no place in binutils should test SHF_GNU_MBIND without first checking OSABI, and SHF_GNU_MBIND should not be set without also setting OSABI. At least, that's the ideal, but the patch accepts SHF_GNU_MBIND on ELFOSABI_NONE object files since gas didn't always set OSABI. However, to reinforce the fact that SHF_GNU_MBIND isn't proper without a non-zero OSABI, readelf will display the flag as LOOS+0 if OSABI isn't set. The clash with SHF_HP_TLS means that hppa64-linux either has that flag on .tbss sections or supports GNU_MBIND, not both. (hppa64-linux users, if there are any, may have noticed that GNU ld since 2017 mysteriously aligned their .tbss sections to a 4k boundary. That was one consequence of SHF_HP_TLS being blindly interpreted as SHF_GNU_MBIND.) Since it seems that binutils, gdb, gcc, glibc, and the linux kernel don't care about SHF_HP_TLS I took that flag out of .tbss for hppa64-linux. bfd/ * elf-bfd.h (enum elf_gnu_osabi): Add elf_gnu_osabi_mbind. * elf.c (_bfd_elf_make_section_from_shdr): Set elf_gnu_osabi_mbind.
