1da177e4 LT |
4 | Intro |
5 | ===== | |
6 | ||
7 | This document is designed to provide a list of the minimum levels of | |
81f10d19 | 8 | software necessary to run the 4.x kernels. |
1da177e4 LT |
9 | |
10 | This document is originally based on my "Changes" file for 2.0.x kernels | |
11 | and therefore owes credit to the same people as that file (Jared Mauch, | |
12 | Axel Boldt, Alessandro Sigala, and countless other users all over the | |
13 | 'net). | |
14 | ||
1da177e4 | 15 | Current Minimal Requirements |
840f6690 | 16 | **************************** |
1da177e4 | 17 | |
840f6690 | 18 | Upgrade to at **least** these software revisions before thinking you've |
1da177e4 LT |
19 | encountered a bug! If you're unsure what version you're currently |
20 | running, the suggested command should tell you. | |
21 | ||
5adaf851 LT |
22 | Again, keep in mind that this list assumes you are already functionally |
23 | running a Linux kernel. Also, not all tools are necessary on all | |
24 | systems; obviously, if you don't have any ISDN hardware, for example, | |
25 | you probably needn't concern yourself with isdn4k-utils. | |

59 | Kernel compilation | |
840f6690 | 60 | ****************** |
1da177e4 LT |
61 | |
62 | GCC | |
63 | --- | |
64 | ||
65 | The gcc version requirements may vary depending on the type of CPU in your | |
a1365647 | 66 | computer. |
1da177e4 LT |
67 | |
68 | Make | |
69 | ---- | |
70 | ||
bf5777bc | 71 | You will need GNU make 3.80 or later to build the kernel. |
1da177e4 LT |
72 | |
73 | Binutils | |
74 | -------- | |
75 | ||
840f6690 MCC |
76 | Linux on IA-32 has recently switched from using ``as86`` to using ``gas`` for |
77 | assembling the 16-bit boot code, removing the need for ``as86`` to compile | |
1da177e4 LT |
78 | your kernel. This change does, however, mean that you need a recent |
79 | release of binutils. | |
80 | ||
08219624 JLPD |
81 | Perl |
82 | ---- | |
83 | ||
840f6690 MCC |
84 | You will need perl 5 and the following modules: ``Getopt::Long``, |
85 | ``Getopt::Std``, ``File::Basename``, and ``File::Find`` to build the kernel. | |
08219624 | 86 | |
221069be A |
87 | BC |
88 | -- | |
89 | ||
90 | You will need bc to build kernels 3.10 and higher | |
91 | ||
08219624 | 92 | |
3f1d44ae DH |
93 | OpenSSL |
94 | ------- | |
95 | ||
96 | Module signing and external certificate handling use the OpenSSL program and | |
97 | crypto library to do key creation and signature generation. | |
98 | ||
99 | You will need openssl to build kernels 3.7 and higher if module signing is | |
100 | enabled. You will also need openssl development packages to build kernels 4.3 | |
101 | and higher. | |
102 | ||

840f6690 | 105 | **************** |
1da177e4 LT |
106 | |
107 | Architectural changes | |
108 | --------------------- | |
109 | ||
110 | DevFS has been obsoleted in favour of udev | |
111 | (http://www.kernel.org/pub/linux/utils/kernel/hotplug/) | |
112 | ||
113 | 32-bit UID support is now in place. Have fun! | |
114 | ||
115 | Linux documentation for functions is transitioning to inline | |
116 | documentation via specially-formatted comments near their | |
117 | definitions in the source. These comments can be combined with the | |
118 | SGML templates in the Documentation/DocBook directory to make DocBook | |
119 | files, which can then be converted by DocBook stylesheets to PostScript, | |
120 | HTML, PDF files, and several other formats. In order to convert from | |
121 | DocBook format to a format of your choice, you'll need to install Jade as | |
122 | well as the desired DocBook stylesheets. | |
123 | ||
124 | Util-linux | |
125 | ---------- | |
126 | ||
840f6690 | 127 | New versions of util-linux provide ``fdisk`` support for larger disks, |
1da177e4 LT |
128 | support new options to mount, recognize more supported partition |
129 | types, have a fdformat which works with 2.4 kernels, and similar goodies. | |
130 | You'll probably want to upgrade. | |
131 | ||
132 | Ksymoops | |
133 | -------- | |
134 | ||
62a07e6e JJ |
135 | If the unthinkable happens and your kernel oopses, you may need the |
136 | ksymoops tool to decode it, but in most cases you don't. | |
840f6690 | 137 | It is generally preferred to build the kernel with ``CONFIG_KALLSYMS`` so |
5adaf851 LT |
138 | that it produces readable dumps that can be used as-is (this also |
139 | produces better output than ksymoops). If for some reason your kernel | |
840f6690 | 140 | is not build with ``CONFIG_KALLSYMS`` and you have no way to rebuild and |
5adaf851 LT |
141 | reproduce the Oops with that option, then you can still decode that Oops |
142 | with ksymoops. | |
1da177e4 LT |
143 | |
144 | Module-Init-Tools | |
145 | ----------------- | |
146 | ||
840f6690 | 147 | A new module loader is now in the kernel that requires ``module-init-tools`` |
1da177e4 LT |
148 | to use. It is backward compatible with the 2.4.x series kernels. |
149 | ||
150 | Mkinitrd | |
151 | -------- | |
152 | ||
840f6690 | 153 | These changes to the ``/lib/modules`` file tree layout also require that |
1da177e4 LT |
154 | mkinitrd be upgraded. |
155 | ||
156 | E2fsprogs | |
157 | --------- | |
158 | ||
840f6690 | 159 | The latest version of ``e2fsprogs`` fixes several bugs in fsck and |
1da177e4 LT |
160 | debugfs. Obviously, it's a good idea to upgrade. |
161 | ||
162 | JFSutils | |
163 | -------- | |
164 | ||
840f6690 | 165 | The ``jfsutils`` package contains the utilities for the file system. |
1da177e4 | 166 | The following utilities are available: |
840f6690 MCC |
167 | |
168 | - ``fsck.jfs`` - initiate replay of the transaction log, and check | |
1da177e4 | 169 | and repair a JFS formatted partition. |
840f6690 MCC |
170 | |
171 | - ``mkfs.jfs`` - create a JFS formatted partition. | |
172 | ||
173 | - other file system utilities are also available in this package. | |
1da177e4 LT |
174 | |
175 | Reiserfsprogs | |
176 | ------------- | |
177 | ||
178 | The reiserfsprogs package should be used for reiserfs-3.6.x | |
179 | (Linux kernels 2.4.x). It is a combined package and contains working | |
840f6690 MCC |
180 | versions of ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` and |
181 | ``reiserfsck``. These utils work on both i386 and alpha platforms. | |
1da177e4 LT |
182 | |
183 | Xfsprogs | |
184 | -------- | |
185 | ||
840f6690 MCC |
186 | The latest version of ``xfsprogs`` contains ``mkfs.xfs``, ``xfs_db``, and the |
187 | ``xfs_repair`` utilities, among others, for the XFS filesystem. It is | |
1da177e4 LT |
188 | architecture independent and any version from 2.0.0 onward should |
189 | work correctly with this version of the XFS kernel code (2.6.0 or | |
190 | later is recommended, due to some significant improvements). | |
191 | ||
5085cb26 DB |
192 | PCMCIAutils |
193 | ----------- | |
194 | ||
840f6690 | 195 | PCMCIAutils replaces ``pcmcia-cs``. It properly sets up |
5085cb26 DB |
196 | PCMCIA sockets at system startup and loads the appropriate modules |
197 | for 16-bit PCMCIA devices if the kernel is modularized and the hotplug | |
198 | subsystem is used. | |
1da177e4 | 199 | |
1da177e4 LT |
200 | Quota-tools |
201 | ----------- | |
202 | ||
203 | Support for 32 bit uid's and gid's is required if you want to use | |
204 | the newer version 2 quota format. Quota-tools version 3.07 and | |
205 | newer has this support. Use the recommended version or newer | |
206 | from the table above. | |
207 | ||
208 | Intel IA32 microcode | |
209 | -------------------- | |
210 | ||
211 | A driver has been added to allow updating of Intel IA32 microcode, | |
890fbae2 GKH |
212 | accessible as a normal (misc) character device. If you are not using |
213 | udev you may need to: | |
1da177e4 | 214 | |
840f6690 MCC |
215 | :: |
216 | ||
217 | mkdir /dev/cpu | |
218 | mknod /dev/cpu/microcode c 10 184 | |
219 | chmod 0644 /dev/cpu/microcode | |
1da177e4 LT |
220 | |
221 | as root before you can use this. You'll probably also want to | |
222 | get the user-space microcode_ctl utility to use with this. | |
223 | ||
1da177e4 LT |
224 | udev |
225 | ---- | |
840f6690 MCC |
226 | |
227 | ``udev`` is a userspace application for populating ``/dev`` dynamically with | |
228 | only entries for devices actually present. ``udev`` replaces the basic | |
03a67a46 | 229 | functionality of devfs, while allowing persistent device naming for |
890fbae2 | 230 | devices. |
1da177e4 | 231 | |
909021ea MS |
232 | FUSE |
233 | ---- | |
234 | ||
235 | Needs libfuse 2.4.0 or later. Absolute minimum is 2.3.0 but mount | |
840f6690 | 236 | options ``direct_io`` and ``kernel_cache`` won't work. |
909021ea | 237 | |
1da177e4 | 238 | Networking |
840f6690 | 239 | ********** |
1da177e4 LT |
240 | |
241 | General changes | |
242 | --------------- | |
243 | ||
244 | If you have advanced network configuration needs, you should probably | |
245 | consider using the network tools from ip-route2. | |
246 | ||
247 | Packet Filter / NAT | |
248 | ------------------- | |
249 | The packet filtering and NAT code uses the same tools like the previous 2.4.x | |
250 | kernel series (iptables). It still includes backwards-compatibility modules | |
251 | for 2.2.x-style ipchains and 2.0.x-style ipfwadm. | |
252 | ||
253 | PPP | |
254 | --- | |
255 | ||
256 | The PPP driver has been restructured to support multilink and to | |
257 | enable it to operate over diverse media layers. If you use PPP, | |
258 | upgrade pppd to at least 2.4.0. | |
259 | ||
890fbae2 | 260 | If you are not using udev, you must have the device file /dev/ppp |
1da177e4 LT |
261 | which can be made by: |
262 | ||
840f6690 MCC |
263 | :: |
264 | ||
265 | mknod /dev/ppp c 108 0 | |
1da177e4 LT |
266 | |
267 | as root. | |
268 | ||
1da177e4 LT |
269 | Isdn4k-utils |
270 | ------------ | |
271 | ||
272 | Due to changes in the length of the phone number field, isdn4k-utils | |
273 | needs to be recompiled or (preferably) upgraded. | |
274 | ||
275 | NFS-utils | |
276 | --------- | |
277 | ||
5adaf851 LT |
278 | In ancient (2.4 and earlier) kernels, the nfs server needed to know |
279 | about any client that expected to be able to access files via NFS. This | |
840f6690 MCC |
280 | information would be given to the kernel by ``mountd`` when the client |
281 | mounted the filesystem, or by ``exportfs`` at system startup. exportfs | |
282 | would take information about active clients from ``/var/lib/nfs/rmtab``. | |
1da177e4 LT |
283 | |
284 | This approach is quite fragile as it depends on rmtab being correct | |
285 | which is not always easy, particularly when trying to implement | |
840f6690 | 286 | fail-over. Even when the system is working well, ``rmtab`` suffers from |
1da177e4 LT |
287 | getting lots of old entries that never get removed. |
288 | ||
5adaf851 LT |
289 | With modern kernels we have the option of having the kernel tell mountd |
290 | when it gets a request from an unknown host, and mountd can give | |
291 | appropriate export information to the kernel. This removes the | |
840f6690 | 292 | dependency on ``rmtab`` and means that the kernel only needs to know about |
5adaf851 | 293 | currently active clients. |
1da177e4 LT |
294 | |
295 | To enable this new functionality, you need to: | |
296 | ||
840f6690 MCC |
297 | :: |
298 | ||
e4121712 | 299 | mount -t nfsd nfsd /proc/fs/nfsd |
1da177e4 LT |
300 | |
301 | before running exportfs or mountd. It is recommended that all NFS | |
302 | services be protected from the internet-at-large by a firewall where | |
303 | that is possible. | |
304 | ||
172d899d AK |
305 | mcelog |
306 | ------ | |
307 | ||
c8c3f7d6 | 308 | On x86 kernels the mcelog utility is needed to process and log machine check |
840f6690 MCC |
309 | events when ``CONFIG_X86_MCE`` is enabled. Machine check events are errors |
310 | reported by the CPU. Processing them is strongly encouraged. | |
172d899d | 311 | |
81f10d19 MCC |
312 | Kernel documentation |
313 | ******************** | |
314 | ||
315 | Sphinx | |
316 | ------ | |
317 | ||
318 | The ReST markups currently used by the Documentation/ files are meant to be | |
319 | built with ``Sphinx`` version 1.2 or upper. If you're desiring to build | |
320 | PDF outputs, it is recommended to use version 1.4.6. | |
321 | ||
322 | .. note:: | |
323 | ||
324 | Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX`` | |
325 | version 3.14159265. Depending on the distribution, you may also need | |
326 | to install a series of ``texlive`` packages that provide the minimal | |
327 | set of functionalities required for ``XeLaTex`` to work. | |
328 | ||
329 | Other tools | |
330 | ----------- | |
331 | ||
332 | In order to produce documentation from DocBook, you'll also need ``xmlto``. | |
333 | Please notice, however, that we're currently migrating all documents to use | |
334 | ``Sphinx``. | |
