x86: Ignore protected visibility in shared libraries on Solaris
On x86, the PLT entry in executable may be used as function address for functions in shared libraries. If functions are protected, the function address used in executable can be different from the function address used in shared library. This will lead to incorrect run-time behavior if function pointer equality is needed. By default, x86 linker issues an error in this case. On Solaris, linker issued an error for struct tm *tb = (kind == CPP_time_kind::FIXED ? gmtime : localtime) (&tt); where gmtime is a protected function in libc.so. Use gmtime's PLT entry in executable as function address is safe since function pointer equality isn't needed. Ignore protected visibility in shared libraries on Solaris to disable linker error. If function pointer equality is needed, linker will silently generate executable with incorrect run-time behavior on Solaris.

x86: Make protected symbols local for -shared
Call _bfd_elf_symbol_refs_local_p with local_protected==true. This has
2 noticeable effects for -shared:
* GOT-generating relocations referencing a protected data symbol no
longer lead to a GLOB_DAT (similar to a hidden symbol).
* Direct access relocations (e.g. R_X86_64_PC32) no longer has the
confusing diagnostic below.
__attribute__((visibility("protected"))) void *foo() {
return (void *)foo;
}
// gcc -fpic -shared -fuse-ld=bfd
relocation R_X86_64_PC32 against protected symbol `foo' can not be used when making a shared object
The new behavior matches arm, aarch64 (commit

Don't encode reloc.size
I expect the encoded reloc.size field originally came from aout r_length ecoding, but somehow went wrong for 64-bit relocs (which should have been encoded as 3).

x86: Disallow invalid relocation against protected symbol
I am checking this into master and will backport it to 2.38 branch. H.J ---- On x86, GCC 12 supports -mno-direct-extern-access to enable canonical reference to protected function and disable copy relocation. With -mno-direct-extern-access, the canonical protected function symbols must be accessed via canonical reference and the protected data symbols in shared libraries are non-copyable. Under glibc 2.35, non-canonical reference to the canonical protected function will get the run-time error: ./y: internal_f: ./libfoo.so: non-canonical reference to canonical protected function and copy relocations against the non-copyable protected symbols will get the run-time error: ./x: internal_i: ./libfoo.so: copy relocation against non-copyable protected symbol Update x86 linker to disallow non-canonical reference to the canonical protected function: ld: plt.o: non-canonical reference to canonical protected function `internal_f' in libfoo.so ld: failed to set dynamic section sizes: bad value and copy relocation against the non-copyable protected symbol: ld: main.o: copy relocation against non-copyable protected symbol `internal_i' in libfoo.so at link-time. bfd/ PR ld/28875 * elf-properties.c (_bfd_elf_parse_gnu_properties): Don't skip shared libraries for GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS. * elf32-i386.c (elf_i386_scan_relocs): Disallow non-canonical reference to canonical protected function. * elf64-x86-64.c (elf_x86_64_scan_relocs): Likewise. * elfxx-x86.c (elf_x86_allocate_dynrelocs): Don't allow copy relocation against non-copyable protected symbol. ld/ PR ld/28875 * testsuite/ld-i386/i386.exp: Check non-canonical reference to canonical protected function and check copy relocation against non-copyable protected symbol. * testsuite/ld-i386/pr21997-1.err: New file. * testsuite/ld-i386/pr28875.err: Likewise. * testsuite/ld-i386/pr28875a.c: Likewise. * testsuite/ld-i386/pr28875b.c: Likewise. * testsuite/ld-x86-64/pr21997-1a.err: Updated. * testsuite/ld-x86-64/pr21997-1b.err: Likewise. * testsuite/ld-x86-64/pr28875-data.err: New file. * testsuite/ld-x86-64/pr28875-func.err: Likewise. * testsuite/ld-x86-64/x86-64.exp: Check non-canonical reference to canonical protected function and check copy relocation against non-copyable protected symbol. |

x86: Add DT_RELR support
DT_RELR is implemented with linker relaxation: 1. During linker relaxation, we scan input relocations with the same logic in relocate_section to determine if a relative relocation should be generated and save the relative relocation candidate information for sizing the DT_RELR section later after all symbols addresses can be determined. For these relative relocations which can't be placed in the DT_RELR section, they will be placed in the rela.dyn/rel.dyn section. 2. When DT_RELR is enabled, _bfd_elf_map_sections_to_segments calls a backend function to size the DT_RELR section which will compute the DT_RELR section size and tell ldelf_map_segments to layout sections again when the DT_RELR section size has been increased. 3. After regular symbol processing is finished, bfd_elf_final_link calls a backend function to finish the DT_RELR section. * elf32-i386.c (elf_i386_relocate_section): Don't generate relative relocation when DT_RELR is enabled.

ld: Extract _bfd_elf_link_iterate_on_relocs
DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global offset table) and data sections in a compact format: https://groups.google.com/g/generic-abi/c/bX460iggiKg On some targets, R_*_RELATIVE relocations are counted and the GOT offsets are allocated when setting the dynamic section sizes after seeing all relocations. R_*_RELATIVE relocations are generated while relocating sections after section layout has been finalized. To prepare for DT_RELR implementation on these targets, extract _bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so that a backend can scan relocations in elf_backend_always_size_sections For x86 targets, the old check_relocs is renamed to scan_relocs and a new check_relocs is added to chek input sections and create dynamic relocation sections so that they will be mapped to output sections. scan_relocs is now called from elf_backend_always_size_sections. Since relocations are scanned after __start, __stop, .startof. and .sizeof. symbols have been finalized on x86, __[start|stop]_SECNAME for --gc-sections -z start-stop-gc are now zero when all SECNAME sections been garbage collected.

x86: don't request useless overflow checking
Relocations with a bitsize matching the architecture's address width can't usefully use an overflow checking approach other than "dont" or "signed": All others involve perhaps complex calculations in _bfd_relocate_contents() (or, not as severe, in bfd_check_overflow()) without ever finding anything to complain about - because of the address width masking applied. Avoid this unnecessary overhead and switch all such reloc types to "dont". Note that "signed" checking with rela relocations (i.e. x86-64 here) is only going to be useful if the addend actually got passed to _bfd_relocate_contents() (and maybe others) instead of bogusly adding in prior section contents (which apparently is assumed to be zero, and hence again no overflow would ever be detected). See https://sourceware.org/pipermail/binutils/2021-April/116164.html. |

x86: correct overflow checking for 16-bit PC-relative relocs
The only insn requiring a truly 16-bit PC-relative relocation outside of 16-bit mode is XBEGIN (with an operand size override). For it, the relocation generated should behave similar to 8- and (for 64-bit) 32-bit PC-relatives ones, i.e. be checked for a signed value to fit the field. This same mode is also correct for 16-bit code. Outside of 16-bit code, branches with operand size overrides act in a truly PC-relative way only when living in the low 32k of address space, as they truncate rIP to 16 bits. This can't be expressed by a PC-relative relocation. Putting in place a new testcase, I'd like to note that the two existing ones (pcrel16 and pcrel16abs) appear to be pretty pointless: They don't expect any error despite supposedly checking for overflow, and in fact there can't possibly be any error for the - former since gas doesn't emit any relocation in the first place there, - latter because the way the relocation gets expressed by gas doesn't allow the linker to notice the overflow; it should be detected by gas if at all, but see above (an error would be reported here for x86-64 afaict, but this test doesn't get re-used there). |

x86: TLS desc call relocs target zero-size fields
These are marker relocations, so together with their bit size being zero their byte size should be zero as well. This is expressed by a value of 3, not 0. |

bfd_size_type to size_t
bfd_size_type was invented a long time ago in the K&R days. 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

bfd_section_* macros
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.

ELF final_write_processing
Move setting of OSABI to final_write_processing, after symbols are written. This allows OSABI to be set based on symbols actually written to the output rather than assuming input symbols will be output. Corrects object files such as the one generated on powerpc64le-linux by ld-powerpc/pr23927.s which has a local STT_GNU_IFUNC symbol but prior to this patch the file was marked ELFOSABI_NONE. * elf-bfd.h (enum elf_gnu_osabi): Rename from elf_gnu_symbols.
