2021-12-07Re: Add support for AArch64 EFI (efi-*-aarch64)Alan Modra1-46/+40
Commit b69c9d41e8 was broken in multiple ways regarding the realloc of the target string, most notably in that "-little" wasn't actually appended to the input_target or output_target. This caused asan errors and "FAIL: Check if efi app format is recognized". I also noticed that the input_target string wasn't being copied but rather the output_target when dealing with the input target. Fix that too. PR 26206 * objcopy.c (convert_efi_target): Rewrite. Allocate modified target strings here.. (copy_main): ..rather than here. Do handle input_target, not output_target for input.

2021-11-23AArch64: Add support for AArch64 EFI (efi-*-aarch64).Tamar Christina4-0/+68
This adds support for efi-*-aarch64 by virtue of adding a new PEI target pei-aarch64-little. 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 aarch64 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. 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].

2021-11-19RISC-V: Support STO_RISCV_VARIANT_CC and DT_RISCV_VARIANT_CC.Nelson Chu1-0/+39
This is the original discussion, https://github.com/riscv/riscv-elf-psabi-doc/pull/190 And here is the glibc part, https://sourceware.org/pipermail/libc-alpha/2021-August/129931.html For binutils part, we need to support a new direcitve: .variant_cc. The function symbol marked by .variant_cc means it need to be resolved directly without resolver for dynamic linker. We also add a new dynamic entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the special attribute in the dynamic symbol table of the object. I heard that llvm already have supported this in their mainline, so I think it's time to commit this. bfd/ * elfnn-riscv.c (riscv_elf_link_hash_table): Added variant_cc flag. It is used to check if relocations for variant CC symbols may be present.

PR 28540 * objdump.c (dump_bfd): Don't attempt load_separate_debug_files when byte_get is NULL.
2021-11-03Use section name in warnings in display_debug_locTom Tromey2-8/+16
While looking at an apparently malformed executable with "readelf --debug-dump=loc", I got this warning: readelf: ./main: Warning: There is a hole [0x89 - 0x95] in .debug_loc section. However, the executable only has a .debug_loclists section. This patch fixes the warning messages in display_debug_loc to use the name of the section that is being processed. binutils/ChangeLog 2021-11-03 Tom Tromey <tromey@adacore.com> * dwarf.c (display_debug_loc): Use section name in warnings.
2021-11-03asan: dlltool buffer overflow: embedded NUL in stringAlan Modra1-4/+2
yyleng gives the pattern length, xstrdup just copies up to the NUL. So it is quite possible writing at an index of yyleng-2 overflows the xstrdup allocated string buffer. xmemdup quite handily avoids this problem, even writing the terminating NUL over the trailing quote. Use it in ldlex.l too where we'd already had a report of this problem and fixed it by hand, and to implement xmemdup0 in gas. binutils/ * deflex.l (single and double quote strings): Use xmemdup. gas/ * as.h (xmemdup0): Use xmemdup. ld/ PR 20906 * ldlex.l (double quote string): Use xmemdup.
2021-11-03asan: assert (addr_ranges) <= (start)Alan Modra1-10/+9
That assert would be more obvious if it were reported as "addr_ranges <= end_ranges". Fix that by using the obvious variable in the final loop. Stop the assertion by using a signed comparison: It's possible for the rounding up of the arange pointer to exceed the end of the block when the block size is fuzzed. * dwarf.c (display_debug_aranges): Use "end_ranges" in loop displaying ranges rather that "start". Simplify rounding up to 2*address_size boundary. Use signed comparison in loop.
2021-11-01objcopy buffer overflowAlan Modra1-12/+9
"tocopy" in this code was an int, which when the size to be copied was larger than MAXINT could result in tocopy being negative. A negative value of course is less than BUFSIZE, but when converted to bfd_size_type is extremely large. PR 995 * objcopy.c (copy_unknown_object): Correct calculation of "tocopy". Use better variable types.
