help
ELF (Executable
and Linkable
Format)
is a
format for libraries
and
executables used across different architectures
and operating
systems. Saying Y here will enable your kernel
to run ELF binaries
and enlarge it
by about
13 KB. ELF support
under Linux has now all
but replaced the traditional Linux a.out formats (QMAGIC
and ZMAGIC)
because it
is portable (this does
*not* mean that you will be able
to run executables
from different architectures
or operating systems
however)
and makes building
run-
time libraries very easy. Many new
executables are distributed solely
in ELF
format. You definitely
want
to say Y here.
Information about ELF
is contained
in the ELF HOWTO available
from
<
http://www.tldp.org/docs.html#howto>.
If you find that after upgrading
from Linux kernel
1.
2 and saying Y
here, you still can
't run any ELF binaries (they just crash), then
you
'll have to install the newest ELF runtime libraries, including
ld.so (
check the
file <
file:Documentation/Changes>
for location
and
latest version).

default KUNIT_ALL_TESTS
help
This builds the ELF loader KUnit tests, which try
to gather
prior bug fixes
into a regression test collection. This
is really
only needed
for debugging. Note that with CONFIG_COMPAT=y, the
compat_binfmt_elf KUnit test
is also created.

select ELFCORE
help
ELF FDPIC binaries are based
on ELF, but allow the individual
load
segments
of a
binary to be located
in memory independently
of each
other. This makes this
format ideal
for use
in environments
where no
MMU
is available
as it still permits
text segments
to be
shared,
even
if data segments are not.
It
is also possible
to run FDPIC ELF binaries
on MMU linux also.
config ELFCORE
bool
help
This option enables kernel/elfcore.o.
config CORE_DUMP_DEFAULT_ELF_HEADERS
bool
"Write ELF core dumps with partial segments"
default y
depends
on BINFMT_ELF && ELF_CORE
help
ELF core dump files
describe each
memory mapping
of the crashed
process,
and can contain
or omit the
memory contents
of each one.
The contents
of an unmodified
text mapping are omitted
by default.
For an unmodified
text mapping
of an ELF
object, including just
the first
page of the
file in a core dump makes it possible
to
identify the build ID bits
in the
file, without paying the i/o
cost
and disk space
to dump all the
text. However, versions
of
GDB before
6.
7 are confused
by ELF core dump files
in this
format.
The core dump behavior can be controlled per process
using
the /proc/PID/coredump_filter pseudo-
file; this setting
is
inherited. See Documentation/filesystems/proc.rst
for details.
This config option changes the default setting
of coredump_filter
seen
at boot
time.
If unsure, say Y.
config BINFMT_SCRIPT
tristate
"Kernel support for scripts starting with #!"
default y
help
Say Y here
if you want
to execute interpreted scripts starting with
#! followed
by the path
to an interpreter.
You can build this support
as a
module; however, until that
module
gets loaded, you cannot
run scripts. Thus,
if you want
to load this
module from an initramfs, the portion
of the initramfs before loading
this
module must consist
of compiled binaries only.
Most systems will not boot
if you say M
or N here.
If unsure, say Y.

config BINFMT_MISC
tristate
"Kernel support for MISC binaries"
help
If you say Y here, it will be possible
to plug wrapper-driven
binary
formats
into the kernel. You will
like this especially
when you use
programs that need an interpreter
to run like Java, Python, .NET
or
Emacs-Lisp. It
's also useful if you often run DOS executables under
the Linux DOS emulator DOSEMU (
read the DOSEMU-HOWTO, available
from
<
http://www.tldp.org/docs.html#howto>). Once you have
registered such a
binary class with the kernel, you can start one
of
those programs simply
by typing
in its name
at a shell prompt; Linux
will automatically feed it
to the correct interpreter.
You can
do other nice things, too.
Read the
file
<
file:Documentation/admin-guide/binfmt-misc.rst>
to learn how
to use this
feature, <
file:Documentation/admin-guide/java.rst>
for information about how
to include Java support.
and <
file:Documentation/admin-guide/mono.rst>
for
information about how
to include Mono-based .NET support.
To use binfmt_misc, you will need
to mount it:
mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
You may say M here
for module support
and later
load the
module when
you have use
for it; the
module is called binfmt_misc.
If you
don
't know what to answer at this point, say Y.
config COREDUMP
bool
"Enable core dump support" if EXPERT
default y
help
This option enables support
for performing core dumps. You almost
certainly want
to say Y here. Not necessary
on systems that never
need debugging
or only ever
run flawless
code.
config EXEC_KUNIT_TEST
bool
"Build execve tests" if !KUNIT_ALL_TESTS
depends
on KUNIT=y
default KUNIT_ALL_TESTS
help
This builds the
exec KUnit tests, which tests boundary conditions
of various aspects
of the
exec internals.
