DESCRIPTION
elfedit updates the ELF header and program property of ELF files which
have the matching ELF machine and file types. The options control how
and which fields in the ELF header and program property should be
updated.
elffile... are the ELF files to be updated. 32-bit and 64-bit ELF files
are supported, as are archives containing ELF files.
OPTIONS
The long and short forms of options, shown here as alternatives, are
equivalent. At least one of the --output-mach, --output-type,
--output-osabi, --output-abiversion, --enable-x86-feature and
--disable-x86-feature options must be given.
--input-mach=machine
Set the matching input ELF machine type to machine. If --input-mach
isn't specified, it will match any ELF machine types.
The supported ELF machine types are, i386, IAMCU, L1OM, K1OM and
x86-64.
--output-mach=machine
Change the ELF machine type in the ELF header to machine. The
supported ELF machine types are the same as --input-mach.
--input-type=type
Set the matching input ELF file type to type. If --input-type isn't
specified, it will match any ELF file types.
The supported ELF file types are, rel, exec and dyn.
--output-type=type
Change the ELF file type in the ELF header to type. The supported
ELF types are the same as --input-type.
--input-osabi=osabi
Set the matching input ELF file OSABI to osabi. If --input-osabi
isn't specified, it will match any ELF OSABIs.
The supported ELF OSABIs are, none, HPUX, NetBSD, GNU, Linux (alias
for GNU), Solaris, AIX, Irix, FreeBSD, TRU64, Modesto, OpenBSD,
OpenVMS, NSK, AROS and FenixOS.
--output-osabi=osabi
Change the ELF OSABI in the ELF header to osabi. The supported ELF
OSABI are the same as --input-osabi.
--input-abiversion=version
Set the matching input ELF file ABIVERSION to version. version must
be between 0 and 255. If --input-abiversion isn't specified, it
will match any ELF ABIVERSIONs.
--output-abiversion=version
Change the ELF ABIVERSION in the ELF header to version. version
must be between 0 and 255.
--enable-x86-feature=feature
Set the feature bit in program property in exec or dyn ELF files
with machine types of i386 or x86-64. The supported features are,
ibt, shstk, lam_u48 and lam_u57.
--disable-x86-feature=feature
Clear the feature bit in program property in exec or dyn ELF files
with machine types of i386 or x86-64. The supported features are
the same as --enable-x86-feature.
Note: --enable-x86-feature and --disable-x86-feature are available
only on hosts with mmap support.
-v
--version
Display the version number of elfedit.
-h
--help
Display the command-line options understood by elfedit.
@file
Read command-line options from file. The options read are inserted
in place of the original @file option. If file does not exist, or
cannot be read, then the option will be treated literally, and not
removed.
Options in file are separated by whitespace. A whitespace character
may be included in an option by surrounding the entire option in
either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The file may itself contain additional @file
options; any such options will be processed recursively.
