* sys/sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326256

* Update ELF headers to include additional definesEd Maste2015-01-021-0/+12
| | | | | | | | | | | | | | | | | The elftoolchain project includes these additional defines for various userland programs. Given that arch-specific defines are still interesting in the context of userland programs reading or writing ELF metadata, they should be included in top-level ELF headers. Remove duplicate defines from ARM and MIPS elf headers.

| | | | | | | | | | | | | | | | means: o Remove Elf64_Quarter, o Redefine Elf64_Half to be 16-bit, o Redefine Elf64_Word to be 32-bit, o Add Elf64_Xword and Elf64_Sxword for 64-bit entities, o Use Elf_Size in MI code to abstract the difference between Elf32_Word and Elf64_Word. o Add Elf_Ssize as the signed counterpart of Elf_Size.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revamp the ELF include files to better support architecture-independentJohn Polstra1998-08-161-164/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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.
