* Get in sync with current ELF definitions. In particular this means:Marcel Moolenaar2005-12-181-48/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | o Remove the unused and non-standard SHT_NUM, PT_COUNT and DT_COUNT. o Add the STV_DEFAULT, STV_INTERNAL, STV_HIDDEN and STV_PROTECTED symbol visibility constants. o Add the ELF32_ST_VISIBILITY and ELF64_ST_VISIBILITY macros to get the symbol visibility from the st_other field. o Add the ELFOSABI_AIX, ELFOSABI_OPENVMS and ELFOSABI_NSK constants. o Add the ET_LOOS, ET_HIOS, ET_LOPROC and ET_HIPROC constants. o Further flesh out the list of machine types. Note that EM_ALPHA remains non-standard. The standard value for EM_ALPHA is given by EM_ALPHA_STD (which is a non-standard name :-) o Add the SHN_LOOS, SHN_HIOS and SHN_XINDEX constants. o Add the SHT_INIT_ARRAY, SHT_FINI_ARRAY, SHT_PREINIT_ARRAY, SHT_GROUP and SHT_SYMTAB_SHNDX constants. o Add the SHF_MERGE, SHF_STRINGS, SHF_INFO_LINK, SHF_LINK_ORDER, SHF_OS_NONCONFORMING, SHF_GROUP and SHF_MASKOS constants. o Add the PF_MASKOS and PF_MASKPROC constants. o Add the STB_LOOS andf STB_HIOS constants. o Add the STT_COMMON, STT_LOOS and STT_HIOS constants.

* Change our ELF binary branding to something more acceptable to the BinutilsDavid E. O'Brien2000-04-181-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | maintainers. After we established our branding method of writing upto 8 characters of the OS name into the ELF header in the padding; the Binutils maintainers and/or SCO (as USL) decided that instead the ELF header should grow two new fields -- EI_OSABI and EI_ABIVERSION. Each of these are an 8-bit unsigned integer. SCO has assigned official values for the EI_OSABI field. In addition to this, the Binutils maintainers and NetBSD decided that a better ELF branding method was to include ABI information in a ".note" ELF section. With this set of changes, we will now create ELF binaries branded using both "official" methods. Due to the complexity of adding a section to a binary, binaries branded with ``brandelf'' will only brand using the EI_OSABI method. Also due to the complexity of pulling a section out of an ELF file vs. poking around in the ELF header, our image activator only looks at the EI_OSABI header field. Note that a new kernel can still properly load old binaries except for Linux static binaries branded in our old method. * * For a short period of time, ``ld'' will also brand ELF binaries * using our old method. This is so people can still use kernel.old * with a new world. This support will be removed before 5.0-RELEASE, * and may not last anywhere upto the actual release. My expiration * time for this is about 6mo. * Notes: svn path=/head/; revision=59342

applications. Here's how it works. The kernel should include <machine/elf.h> to get the definitions for the native architecture. It can reference the various ELF structures with generic names like Elf_Sym, Elf_Shdr, etc. A define __ELF_WORD_SIZE is also available with the value 32 or 64 as appropriate for the native architecture. Generic applications should include <elf.h>, which is just a wrapper for <machine/elf.h>. Applications such as object file dumpers that need to deal with foreign ELF files can include <sys/elf32.h> and/or <sys/elf64.h>. Both can be included from the same source file if desired. The structure names must be referenced using wordsize-specific names like Elf32_Sym, Elf64_Shdr, etc. I haven't change the alpha stuff, but I haven't broken it either.
