* PE dos_messageAlan Modra2023-08-271-3/+2
| | | | | | | | | | | | | | | | | | | | | | | I was looking at dos_message and wondering why we have H_PUT_32 in _bfd_XXi_only_swap_filehdr_out but no H_GET_32 in pe_bfd_object_p. On a big-endian machine this would result in scrambling the code and strings constained in dos_message. Rather than fix the lack of H_GET_32 in pe_bfd_object_p, I decided it doesn't make sense to store dos_message internally as an array of ints. include/ * coff/internal.h (struct internal_extra_pe_filehdr): Make dos_message a char array. * coff/msdos.h (struct external_DOS_hdr): Flatten dos_message. * coff/pe.h (struct external_PEI_filehdr): Likewise. bfd/ * libcoff-in.h (struct pe_tdata): Make dos_message a char array. * libcoff.h: Regenerate. * peXXigen.c (_bfd_XXi_only_swap_filehdr_out): memcpy dos_message to output. * peicode.h (pe_mkobject): Don't memset already zeroed pe_opthdr.

* Use stdint types in coff internal_auxentAlan Modra2023-03-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | long is a poor choice of type to store 32-bit values read from objects files by H_GET_32. H_GET_32 doesn't sign extend so tests like that in gdb/coffread.c for "negative" values won't work if long is larger than 32 bits. If long is 32-bit then code needs to be careful to not accidentally index negative array elements. (I'd rather see a segfault on an unmapped 4G array index than silently reading bogus data.) long is also a poor choice for x_sect.s_scnlen, which might have 64-bit values. It's better to use unsigned exact width types to avoid surprises. I decided to change the field names too, which makes most of this patch simply renaming. Besides that there are a few places where casts are no longer needed, and where printf format strings or tests need adjusting. include/ * coff/internal.h (union internal_auxent): Use unsigned stdint types. Rename l fields to u32 and u64 as appropriate. bfd/ * coff-bfd.c, * coff-rs6000.c, * coff64-rs6000.c, * coffcode.h, * coffgen.c, * cofflink.c, * coffswap.h, * peXXigen.c, * xcofflink.c: Adjust to suit internal_auxent changes. binutils/ * rdcoff.c: Adjust to suit internal_auxent changes. gas/ * config/obj-coff.h, * config/tc-ppc.c: Adjust to suit internal_auxent changes. gdb/ * coffread.c, * xcoffread.c: Adjust to suit internal_auxent changes. ld/ * pe-dll.c: Adjust to suit internal_auxent changes.
* PE fake section for C_SECTION symsAlan Modra2023-03-221-12/+2
| | | | | | | | | | | It's an odd thing to have objdump -x show a different section table to objdump -h, but that can happen if swapping in symbols leads to creating sections. Setting SEC_LINKER_CREATED stops the display of these sections, so that you get shown what is in the object file. * peXXigen.c (_bfd_XXi_swap_sym_in): Set SEC_LINKER_CREATED on fake section created for C_SECTION syms. Don't zero asection fields that are already zero.

These size checks are not done for bss style sections, because they typically don't occupy file space and thus can't be compared against file size.

* PR29653, objcopy/strip: fuzzed small input file induces large output fileAlan Modra2022-10-071-37/+18
| | | | | | | | | | | | | | | | | | | | | | | _bfd_check_format functions should not print errors or warnings if they return NULL. A NULL return means the particular target under test does not match, so there isn't any reason to make a complaint about the target. In fact there isn't a good reason to warn even if the target matches, except via the _bfd_per_xvec_warn mechanism; Some other target might be a better match. This patch tidies pe_bfd_object_p with the above in mind, and restricts the PE optional header SectionAlignment and FileAlignment fields somewhat. I chose to warn on nonsense values rather than refusing to match. Refusing to match would be OK too. PR 29653 * peXXigen.c (_bfd_XXi_swap_aouthdr_in): Don't emit error about invalid NumberOfRvaAndSizes here. Limit loop copying data directory to IMAGE_NUMBEROF_DIRECTORY_ENTRIES. * peicode.h (pe_bfd_object_p): Don't clear and test bfd_error around bfd_coff_swap_aouthdr_in. Warn on invalid SectionAlignment, FileAlignment and NumberOfRvaAndSizes. Don't return NULL on invalid NumberOfRvaAndSizes.

This is not a full target and only exists to support EFI at this time. This means that this target does not support relocation processing and is mostly a container format. This format has been added to elf based loongarch64 targets such that efi images can be made natively on Linux. However this target is not valid for use with gas but only with objcopy. We should't limit addresses to 32-bits for 64-bit vma, otherwise there will be "RVA truncated" error when using objcopy on loongarch64. With these changes the resulting file is recognized as an efi image. Any magic number is based on the Microsoft PE specification [1].

With these changes the resulting file is recognized as an efi image by third party tools: > pecli info hello.efi Metadata ================================================================================ MD5: 598c32a778b0f0deebe977fef8578c4e SHA1: 4580121edd5cb4dc40f51b28f171fd15250df84c SHA256: 3154bd7cf42433d1c957f6bf55a17ad8c57ed41b29df2d485703349fd6ff1d5c Imphash: Size: 47561 bytes Type: PE32+ executable (EFI application) (stripped to external PDB), for MS Windows Compile Time: 1970-01-01 00:00:00 (UTC - 0x0 ) Entry point: 0x2000 (section .text) Sections ================================================================================ Name RWX VirtSize VirtAddr RawAddr RawSize Entropy md5 .text R-X 0x5bb0 0x2000 0x400 0x5c00 6.39 551fbc264256a3f387de8a891500ae0d .reloc R-- 0xc 0x8000 0x6000 0x200 0.02 0c45f6d812d079821c1d54c09ab89e1d .data RW- 0x1d88 0x9000 0x6200 0x1e00 4.18 5d1137c09f01289dc62bf754f7290db3 .dynamic RW- 0xf0 0xb000 0x8000 0x200 0.34 5c94ed3206f05a277e6f04fbf131f131 .rela R-- 0xe58 0xc000 0x8200 0x1000 1.87 8b5c6bc30f3acb7ca7bf2e6789d68519 .dynsym R-- 0x138 0xd000 0x9200 0x200 0.96 bdcf5101da51aadc663ca8859f88138c Imports ================================================================================ Any magic number is based on the Microsoft PE specification [1].

* bfd: don't silently wrap or truncate PE image section RVAsJan Beulich2021-03-091-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | In PE images section addresses get expressed as addresses relative to the image base. Therefore the VA of a section must be no less than the image base, and after subtraction of the image base the resulting value should fit in 32 bits. (The issue is particularly obvious to notice when sections, perhaps because of ELF assumptions, get placed at VA 0 by default. Debugging info sections as well as .comment, when input files are ELF, are a good example. All such sections need proper mentioning in the linker script to avoid this warning.) There are a number of test cases which previously produced bogus images, yet still declared the test a success. Like done for other tests already, force a zero image base for these. This then also allows (and requires) dropping again xfail-s which 39a7b38fac0e ("Fix linker tests to work with 16-bit targets") had added to ld-scripts/default-script*.d (originally as skip-s). This also depends on similar adjustments to testsuite/ld-scripts/map-address.* made by an earlier patch. For ld-scripts/print-memory-usage.* I suppose xcoff could be dropped from the exclusion list by suppressing garbage collection, just like already done in e.g. (as seen in the diff here) ld-scripts/data.*, but I didn't want to make unrelated adjustments.

* fix objcopy of PE images with .buildid sectionJan Beulich2020-08-211-15/+19
| | | | | | | | | | | | | | | | | | | | | Xen Project embeds a build ID in its hypervisor binary (including its EFI variant), living in a standalone section. This usually gets placed right after .rodata, and due to the rounding done on the (file) size of .rodata the two sections appear to overlap (as far as e.g. find_section_by_vma() is concerned). With the first byte "found" in .rodata, nothing guarantees that the entire debug dir fits in that section, leading to apparently random failure of objcopy on such an image. Possible alternatives to the solution chosen: - make find_section_by_vma() honor virt_size, - correct the recording of sizes elsewhere (ibfd has size == virt_size, while obfd doesn't), - fix the linker to avoid producing apparently overlapping sections. While touching the condition around and the contents of the disgnostic, pull it up ahead of the bfd_malloc_and_get_section() call: There's no point first obtaining the section contents, in order to then fail.

Many places in binutils ought to be using size_t instead (and there are lots of places that use long or unsigned long that really ought to use size_t too). Note that you can't change everything over to size_t: A 32-bit host needs a larger type than size_t to support reading and processing of 64-bit ELF object files. This patch just tidies some of the more obvious uses of bfd_size_type that could be size_t. There no doubt are more lurking in the source. Incidentally, practically all functions used for output of object files can use size_t and don't need to worry about overflow of size expressions. If you have something like symcount * sizeof (void *) when symcount is counting symbols already in memory then you know that this expression can't overflow since the size of a symbol in memory is larger by far than that of a pointer. * aix386-core.c (aix386_core_file_p): Use size_t for "amt". * aout-target.h (object_p): Likewise. * aout-tic30.c (tic30_aout_object_p): Likewise. * aoutx.h

To quote from the PE specification [1]: "The presence of an entry of type IMAGE_DEBUG_TYPE_REPRO indicates the PE file is built in a way to achieve determinism or reproducibility. If the input does not change, the output PE file is guaranteed to be bit-for-bit identical no matter when or where the PE is produced. Various date/time stamp fields in the PE file are filled with part or all the bits from a calculated hash value that uses PE file content as input, and therefore no longer represent the actual date and time when a PE file or related specific data within the PE is produced. The raw data of this debug entry may be empty, or may contain a calculated hash value preceded by a four-byte value that represents the hash value length."
