Intro

|
=====
|
|
|
|
|
|
|
|
|
|
This document is designed to provide a list of the minimum levels of
|
|
|
|
|
software necessary to run the 2.6 kernels, as well as provide brief
|
|
|
|
|
instructions regarding any other "Gotchas" users may encounter when
|
|
|
|
|
trying life on the Bleeding Edge. If upgrading from a pre-2.4.x
|
|
|
|
|
kernel, please consult the Changes file included with 2.4.x kernels for
|
|
|
|
|
additional information; most of that information will not be repeated
|
|
|
|
|
here. Basically, this document assumes that your system is already
|
|
|
|
|
functional and running at least 2.4.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 2.4 kernel. Also, not all tools are
|
2005-06-28 07:28:45 +08:00
|
|
|
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
|
2006-01-08 17:04:09 +08:00
|
|
|
computer.
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
Make
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
You will need Gnu make 3.79.1 or later to build the kernel.
|
|
|
|
|
|
|
|
|
|
Binutils
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
Linux on IA-32 has recently switched from using as86 to using gas for
|
|
|
|
|
assembling the 16-bit boot code, removing the need for as86 to compile
|
|
|
|
|
your kernel. This change does, however, mean that you need a recent
|
|
|
|
|
release of binutils.
|
|
|
|
|
|
|
|
|
|
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 the
|
|
|
|
|
SGML templates in the Documentation/DocBook directory to make DocBook
|
|
|
|
|
files, which can then be converted by DocBook stylesheets to PostScript,
|
|
|
|
|
HTML, PDF files, and several other formats. In order to convert from
|
|
|
|
|
DocBook format to a format of your choice, you'll need to install Jade as
|
|
|
|
|
well as the desired DocBook stylesheets.
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
--------
|
|
|
|
|
|
2005-11-07 17:01:03 +08:00
|
|
|
If the unthinkable happens and your kernel oopses, you may need the
|
|
|
|
|
ksymoops tool to decode it, but in most cases you don't.
|
|
|
|
|
In the 2.6 kernel 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.
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
Module-Init-Tools
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
A new module loader is now in the kernel that requires module-init-tools
|
|
|
|
|
to use. It is backward compatible with the 2.4.x series kernels.
|
|
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
o fsck.jfs - initiate replay of the transaction log, and check
|
|
|
|
|
and repair a JFS formatted partition.
|
|
|
|
|
o mkfs.jfs - create a JFS formatted partition.
|
|
|
|
|
o 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).
|
|
|
|
|
|
2005-06-28 07:28:45 +08:00
|
|
|
PCMCIAutils
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
PCMCIAutils replaces pcmcia-cs (see below). 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.
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
Pcmcia-cs
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
PCMCIA (PC Card) support is now partially implemented in the main
|
2005-06-28 07:28:45 +08:00
|
|
|
kernel source. The "pcmciautils" package (see above) replaces pcmcia-cs
|
|
|
|
|
for newest kernels.
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
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,
|
2005-06-21 12:15:16 +08:00
|
|
|
accessible as a normal (misc) character device. If you are not using
|
|
|
|
|
udev you may need to:
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
Powertweak
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
If you are running v0.1.17 or earlier, you should upgrade to
|
|
|
|
|
version v0.99.0 or higher. Running old versions may cause problems
|
|
|
|
|
with programs using shared memory.
|
|
|
|
|
|
|
|
|
|
udev
|
|
|
|
|
----
|
|
|
|
|
udev is a userspace application for populating /dev dynamically with
|
2005-06-21 12:15:16 +08:00
|
|
|
only entries for devices actually present. udev replaces the basic
|
|
|
|
|
functionality of devfs, while allowing persistant device naming for
|
|
|
|
|
devices.
|
2005-04-17 06:20:36 +08:00
|
|
|
|
2005-09-28 12:45:20 +08:00
|
|
|
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.
|
|
|
|
|
|
2005-04-17 06:20:36 +08:00

|
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.
|
|
|
|
|
|
2005-06-21 12:15:16 +08:00
|
|
|
If you are not using udev, you must have the device file /dev/ppp
|
2005-04-17 06:20:36 +08:00
|
|
|
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 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 2.6 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:
|
|
|
|
|
|
2006-09-12 00:39:19 +08:00
|
|
|
mount -t nfsd nfsd /proc/fs/nfsd
|
2005-04-17 06:20:36 +08:00
|
|
|
|
|
|
|
|
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.
