 Minimal requirements to compile the Kernel
 ++++++++++++++++++++++++++++++++++++++++++

 Intro
 =====

 This document is designed to provide a list of the minimum levels of
 software necessary to run the 4.x kernels.

 This document is originally based on my "Changes" file for 2.0.x kernels
 and therefore owes credit to the same people as that file (Jared Mauch,
 Axel Boldt, Alessandro Sigala, and countless other users all over the
 'net).

 Current Minimal Requirements
 ****************************

 Upgrade to at **least** these software revisions before thinking you've
 encountered a bug!  If you're unsure what version you're currently
 running, the suggested command should tell you.

 Again, keep in mind that this list assumes you are already functionally
 running a Linux kernel.  Also, not all tools are necessary on all
 systems; obviously, if you don't have any ISDN hardware, for example,
 you probably needn't concern yourself with isdn4k-utils.

 Kernel compilation
 ******************

 GCC
 ---

 The gcc version requirements may vary depending on the type of CPU in your
 computer.

 Clang/LLVM (optional)
 ---------------------

 The latest formal release of clang and LLVM utils (according to
 `releases.llvm.org <https://releases.llvm.org>`_) are supported for building
 kernels. Older releases aren't guaranteed to work, and we may drop workarounds
 from the kernel that were used to support older versions. Please see additional
 docs on :ref:`Building Linux with Clang/LLVM <kbuild_llvm>`.

 Make
 ----

 You will need GNU make 3.81 or later to build the kernel.

 Binutils
 --------

 The build system has, as of 4.13, switched to using thin archives (`ar T`)
 rather than incremental linking (`ld -r`) for built-in.o intermediate steps.
 This requires binutils 2.20 or newer.

 Perl
 ----

 You will need perl 5 and the following modules: ``Getopt::Long``,
 ``Getopt::Std``, ``File::Basename``, and ``File::Find`` to build the kernel.

 BC
 --

 You will need bc to build kernels 3.10 and higher


 OpenSSL
 -------

 Module signing and external certificate handling use the OpenSSL program and
 crypto library to do key creation and signature generation.

 You will need openssl to build kernels 3.7 and higher if module signing is
 enabled.  You will also need openssl development packages to build kernels 4.3
 and higher.


 System utilities
 ****************

 Architectural changes
 ---------------------

 DevFS has been obsoleted in favour of udev
 (http://www.kernel.org/pub/linux/utils/kernel/hotplug/)

 32-bit UID support is now in place.  Have fun!

 Linux documentation for functions is transitioning to inline
 documentation via specially-formatted comments near their
 definitions in the source.  These comments can be combined with ReST
 files the Documentation/ directory to make enriched documentation, which can
 then be converted to PostScript, HTML, LaTex, ePUB and PDF files.
 In order to convert from ReST format to a format of your choice, you'll need
 Sphinx.

 Util-linux
 ----------

 New versions of util-linux provide ``fdisk`` support for larger disks,
 support new options to mount, recognize more supported partition
 types, have a fdformat which works with 2.4 kernels, and similar goodies.
 You'll probably want to upgrade.

 Ksymoops
 --------

 If the unthinkable happens and your kernel oopses, you may need the
 ksymoops tool to decode it, but in most cases you don't.
 It is generally preferred to build the kernel with ``CONFIG_KALLSYMS`` so
 that it produces readable dumps that can be used as-is (this also
 produces better output than ksymoops).  If for some reason your kernel
 is not build with ``CONFIG_KALLSYMS`` and you have no way to rebuild and
 reproduce the Oops with that option, then you can still decode that Oops
 with ksymoops.

 Mkinitrd
 --------

 These changes to the ``/lib/modules`` file tree layout also require that
 mkinitrd be upgraded.

 E2fsprogs
 ---------

 The latest version of ``e2fsprogs`` fixes several bugs in fsck and
 debugfs.  Obviously, it's a good idea to upgrade.

 JFSutils
 --------

 The ``jfsutils`` package contains the utilities for the file system.
 The following utilities are available:

 - ``fsck.jfs`` - initiate replay of the transaction log, and check
   and repair a JFS formatted partition.

 - ``mkfs.jfs`` - create a JFS formatted partition.

 - other file system utilities are also available in this package.

 Reiserfsprogs
 -------------

 The reiserfsprogs package should be used for reiserfs-3.6.x
 (Linux kernels 2.4.x). It is a combined package and contains working
 versions of ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` and
 ``reiserfsck``. These utils work on both i386 and alpha platforms.

 Xfsprogs
 --------

 The latest version of ``xfsprogs`` contains ``mkfs.xfs``, ``xfs_db``, and the
 ``xfs_repair`` utilities, among others, for the XFS filesystem.  It is
 architecture independent and any version from 2.0.0 onward should
 work correctly with this version of the XFS kernel code (2.6.0 or
 later is recommended, due to some significant improvements).

 PCMCIAutils
 -----------

 PCMCIAutils replaces ``pcmcia-cs``. It properly sets up
 PCMCIA sockets at system startup and loads the appropriate modules
 for 16-bit PCMCIA devices if the kernel is modularized and the hotplug
 subsystem is used.

 Quota-tools
 -----------

 Support for 32 bit uid's and gid's is required if you want to use
 the newer version 2 quota format.  Quota-tools version 3.07 and
 newer has this support.  Use the recommended version or newer
 from the table above.

 Intel IA32 microcode
 --------------------

 A driver has been added to allow updating of Intel IA32 microcode,
 accessible as a normal (misc) character device.  If you are not using
 udev you may need to::

   mkdir /dev/cpu
   mknod /dev/cpu/microcode c 10 184
   chmod 0644 /dev/cpu/microcode

 as root before you can use this.  You'll probably also want to
 get the user-space microcode_ctl utility to use with this.

 udev
 ----

 ``udev`` is a userspace application for populating ``/dev`` dynamically with
 only entries for devices actually present. ``udev`` replaces the basic
 functionality of devfs, while allowing persistent device naming for
 devices.

 FUSE
 ----

 Needs libfuse 2.4.0 or later.  Absolute minimum is 2.3.0 but mount
 options ``direct_io`` and ``kernel_cache`` won't work.

 Networking
 **********

 General changes
 ---------------

 If you have advanced network configuration needs, you should probably
 consider using the network tools from ip-route2.

 Packet Filter / NAT
 -------------------
 The packet filtering and NAT code uses the same tools like the previous 2.4.x
 kernel series (iptables).  It still includes backwards-compatibility modules
 for 2.2.x-style ipchains and 2.0.x-style ipfwadm.

 PPP
 ---

 The PPP driver has been restructured to support multilink and to
 enable it to operate over diverse media layers.  If you use PPP,
 upgrade pppd to at least 2.4.0.

 If you are not using udev, you must have the device file /dev/ppp
 which can be made by::

   mknod /dev/ppp c 108 0

 as root.

 Isdn4k-utils
 ------------

 Due to changes in the length of the phone number field, isdn4k-utils
 needs to be recompiled or (preferably) upgraded.

 NFS-utils
 ---------

 In ancient (2.4 and earlier) kernels, the nfs server needed to know
 about any client that expected to be able to access files via NFS.  This
 information would be given to the kernel by ``mountd`` when the client
 mounted the filesystem, or by ``exportfs`` at system startup.  exportfs
 would take information about active clients from ``/var/lib/nfs/rmtab``.

 This approach is quite fragile as it depends on rmtab being correct
 which is not always easy, particularly when trying to implement
 fail-over.  Even when the system is working well, ``rmtab`` suffers from
 getting lots of old entries that never get removed.

 With modern kernels we have the option of having the kernel tell mountd
 when it gets a request from an unknown host, and mountd can give
 appropriate export information to the kernel.  This removes the
 dependency on ``rmtab`` and means that the kernel only needs to know about
 currently active clients.

 To enable this new functionality, you need to::

   mount -t nfsd nfsd /proc/fs/nfsd

 before running exportfs or mountd.  It is recommended that all NFS
 services be protected from the internet-at-large by a firewall where
 that is possible.

 mcelog
 ------

 On x86 kernels the mcelog utility is needed to process and log machine check
 events when ``CONFIG_X86_MCE`` is enabled. Machine check events are errors
 reported by the CPU. Processing them is strongly encouraged.
