In revision 1.35 EI_BRAND was removed in conjunction with EI_OSABI and EI_ABIVERSION being added, but it looks like this has not been reflected in elf(5). The only place EI_BRAND appears in OpenBSD's current source tree is this man page, as such I think it's worth removing.
For a quick comparison to other systems FreeBSD still mentions EI_BRAND but NetBSD does not (and never appeared to document this in any man page). With regards to EI_OSABI and EI_ABIVERSION FreeBSD covers the defined values whereas NetBSD does not as they note only ELFOSABI_SYSV is used. On the other hand FreeBSD does indeed mark native binaries as ELFOSABI_FREEBSD. Further afield in Linux EI_BRAND was removed, EI_OSABI and EI_ABIVERSION defined values are covered similar to FreeBSD. The diff below removes mention of EI_BRAND and uncomments the EI_OSABI and EI_ABIVERSION parts which appear to have been present since the initial appearance of this man page. In addition I've added the mention of the Modesto and OpenBSD EI_OSABI values as they are defined in sys/sys/exec_elf.h. diff --git a/share/man/man5/elf.5 b/share/man/man5/elf.5 index 57b0bf0da4d..6ce92ef9bb4 100644 --- a/share/man/man5/elf.5 +++ b/share/man/man5/elf.5 @@ -207,51 +207,56 @@ Invalid version. .It Dv EV_CURRENT Current version. .El -.\" .It Dv EI_OSABI -.\" This byte identifies the operating system -.\" and ABI to which the object is targeted. -.\" Some fields in other ELF structures have flags -.\" and values that have platform specific meanings; -.\" the interpretation of those fields is determined by the value of this byte. -.\" The following values are currently defined: -.\" .Pp -.\" .Bl -tag -width "ELFOSABI_STANDALONE" -compact -.\" .It Dv ELFOSABI_SYSV -.\" UNIX System V ABI. -.\" .It Dv ELFOSABI_HPUX -.\" HP-UX operating system ABI. -.\" .It Dv ELFOSABI_NETBSD -.\" .Nx -.\" operating system ABI. -.\" .It Dv ELFOSABI_LINUX -.\" GNU/Linux operating system ABI. -.\" .It Dv ELFOSABI_HURD -.\" GNU/Hurd operating system ABI. -.\" .It Dv ELFOSABI_86OPEN -.\" 86Open Common IA32 ABI. -.\" .It Dv ELFOSABI_SOLARIS -.\" Solaris operating system ABI. -.\" .It Dv ELFOSABI_MONTEREY -.\" Monterey project ABI. -.\" .It Dv ELFOSABI_IRIX -.\" IRIX operating system ABI. -.\" .It Dv ELFOSABI_FREEBSD -.\" .Fx -.\" operating system ABI. -.\" .It Dv ELFOSABI_TRU64 -.\" TRU64 UNIX operating system ABI. -.\" .It Dv ELFOSABI_ARM -.\" ARM architecture ABI. -.\" .It Dv ELFOSABI_STANDALONE -.\" Stand-alone (embedded) ABI. -.\" .El -.\" .It Dv EI_ABIVERSION -.\" This byte identifies the version of the ABI -.\" to which the object is targeted. -.\" This field is used to distinguish among incompatible versions of an ABI. -.\" The interpretation of this version number -.\" is dependent on the ABI identified by the EI_OSABI field. -.\" Applications conforming to this specification use the value 0. +.It Dv EI_OSABI +This byte identifies the operating system +and ABI to which the object is targeted. +Some fields in other ELF structures have flags +and values that have platform specific meanings; +the interpretation of those fields is determined by the value of this byte. +The following values are currently defined: +.Pp +.Bl -tag -width "ELFOSABI_STANDALONE" -compact +.It Dv ELFOSABI_SYSV +UNIX System V ABI. +.It Dv ELFOSABI_HPUX +HP-UX operating system ABI. +.It Dv ELFOSABI_NETBSD +.Nx +operating system ABI. +.It Dv ELFOSABI_LINUX +GNU/Linux operating system ABI. +.It Dv ELFOSABI_HURD +GNU/Hurd operating system ABI. +.It Dv ELFOSABI_86OPEN +86Open Common IA32 ABI. +.It Dv ELFOSABI_SOLARIS +Solaris operating system ABI. +.It Dv ELFOSABI_MONTEREY +Monterey project ABI. +.It Dv ELFOSABI_IRIX +IRIX operating system ABI. +.It Dv ELFOSABI_FREEBSD +.Fx +operating system ABI. +.It Dv ELFOSABI_TRU64 +TRU64 UNIX operating system ABI. +.It Dv ELFOSABI_MODESTO +Modesto operating system ABI. +.It Dv ELFOSABI_OPENBSD +.Ox +operating system ABI. +.It Dv ELFOSABI_ARM +ARM architecture ABI. +.It Dv ELFOSABI_STANDALONE +Stand-alone (embedded) ABI. +.El +.It Dv EI_ABIVERSION +This byte identifies the version of the ABI +to which the object is targeted. +This field is used to distinguish among incompatible versions of an ABI. +The interpretation of this version number +is dependent on the ABI identified by the EI_OSABI field. +Applications conforming to this specification use the value 0. .It Dv EI_PAD Start of padding.
