6 | Intro |
7 | ===== | |
8 | ||
9 | This document is designed to provide a list of the minimum levels of | |
5a5866c2 | 10 | software necessary to run the current kernel version. |
1da177e4 LT |
11 | |
12 | This document is originally based on my "Changes" file for 2.0.x kernels | |
13 | and therefore owes credit to the same people as that file (Jared Mauch, | |
14 | Axel Boldt, Alessandro Sigala, and countless other users all over the | |
15 | 'net). | |
16 | ||
1da177e4 | 17 | Current Minimal Requirements |
840f6690 | 18 | **************************** |
1da177e4 | 19 | |
840f6690 | 20 | Upgrade to at **least** these software revisions before thinking you've |
1da177e4 LT |
21 | encountered a bug! If you're unsure what version you're currently |
22 | running, the suggested command should tell you. | |
23 | ||
5adaf851 LT |
24 | Again, keep in mind that this list assumes you are already functionally |
25 | running a Linux kernel. Also, not all tools are necessary on all | |
9c3c0c20 AB |
26 | systems; obviously, if you don't have any PC Card hardware, for example, |
27 | you probably needn't concern yourself with pcmciautils. | |

67 | Kernel compilation | |
840f6690 | 68 | ****************** |
1da177e4 LT |
69 | |
70 | GCC | |
71 | --- | |
72 | ||
73 | The gcc version requirements may vary depending on the type of CPU in your | |
a1365647 | 74 | computer. |
1da177e4 | 75 | |
3519c4d6 ND |
76 | Clang/LLVM (optional) |
77 | --------------------- | |
78 | ||
79 | The latest formal release of clang and LLVM utils (according to | |
80 | `releases.llvm.org <https://releases.llvm.org>`_) are supported for building | |
81 | kernels. Older releases aren't guaranteed to work, and we may drop workarounds | |
82 | from the kernel that were used to support older versions. Please see additional | |
83 | docs on :ref:`Building Linux with Clang/LLVM <kbuild_llvm>`. | |
84 | ||
d07479b2 MO |
85 | Rust (optional) |
86 | --------------- | |
87 | ||
88 | A particular version of the Rust toolchain is required. Newer versions may or | |
89 | may not work because the kernel depends on some unstable Rust features, for | |
90 | the moment. | |
91 | ||
92 | Each Rust toolchain comes with several "components", some of which are required | |
93 | (like ``rustc``) and some that are optional. The ``rust-src`` component (which | |
94 | is optional) needs to be installed to build the kernel. Other components are | |
95 | useful for developing. | |
96 | ||
97 | Please see Documentation/rust/quick-start.rst for instructions on how to | |
98 | satisfy the build requirements of Rust support. In particular, the ``Makefile`` | |
99 | target ``rustavailable`` is useful to check why the Rust toolchain may not | |
100 | be detected. | |
101 | ||
102 | bindgen (optional) | |
103 | ------------------ | |
104 | ||
105 | ``bindgen`` is used to generate the Rust bindings to the C side of the kernel. | |
106 | It depends on ``libclang``. | |
107 | ||
1da177e4 LT |
108 | Make |
109 | ---- | |
110 | ||
0715fdb0 | 111 | You will need GNU make 3.82 or later to build the kernel. |
1da177e4 | 112 | |
da4288b9 MY |
113 | Bash |
114 | ---- | |
115 | ||
116 | Some bash scripts are used for the kernel build. | |
117 | Bash 4.2 or newer is needed. | |
118 | ||
1da177e4 LT |
119 | Binutils |
120 | -------- | |
121 | ||
e4412739 | 122 | Binutils 2.25 or newer is needed to build the kernel. |
1da177e4 | 123 | |
4ab3b801 RD |
124 | pkg-config |
125 | ---------- | |
126 | ||
127 | The build system, as of 4.18, requires pkg-config to check for installed | |
128 | kconfig tools and to determine flags settings for use in | |
fd65465b | 129 | 'make {g,x}config'. Previously pkg-config was being used but not |
4ab3b801 RD |
130 | verified or documented. |
131 | ||
033dba2e MY |
132 | Flex |
133 | ---- | |
134 | ||
135 | Since Linux 4.16, the build system generates lexical analyzers | |
136 | during build. This requires flex 2.5.35 or later. | |
137 | ||
138 | ||
139 | Bison | |
140 | ----- | |
141 | ||
142 | Since Linux 4.16, the build system generates parsers | |
143 | during build. This requires bison 2.0 or later. | |
144 | ||
333b11e5 ACM |
145 | pahole: |
146 | ------- | |
147 | ||
148 | Since Linux 5.2, if CONFIG_DEBUG_INFO_BTF is selected, the build system | |
149 | generates BTF (BPF Type Format) from DWARF in vmlinux, a bit later from kernel | |
150 | modules as well. This requires pahole v1.16 or later. | |
151 | ||
152 | It is found in the 'dwarves' or 'pahole' distro packages or from | |
153 | https://fedorapeople.org/~acme/dwarves/. | |
154 | ||
08219624 JLPD |
155 | Perl |
156 | ---- | |
157 | ||
840f6690 MCC |
158 | You will need perl 5 and the following modules: ``Getopt::Long``, |
159 | ``Getopt::Std``, ``File::Basename``, and ``File::Find`` to build the kernel. | |
08219624 | 160 | |
221069be A |
161 | BC |
162 | -- | |
163 | ||
164 | You will need bc to build kernels 3.10 and higher | |
165 | ||
08219624 | 166 | |
3f1d44ae DH |
167 | OpenSSL |
168 | ------- | |
169 | ||
170 | Module signing and external certificate handling use the OpenSSL program and | |
171 | crypto library to do key creation and signature generation. | |
172 | ||
173 | You will need openssl to build kernels 3.7 and higher if module signing is | |
174 | enabled. You will also need openssl development packages to build kernels 4.3 | |
175 | and higher. | |
176 | ||
177 | ||
1da177e4 | 178 | System utilities |
840f6690 | 179 | **************** |
1da177e4 LT |
180 | |
181 | Architectural changes | |
182 | --------------------- | |
183 | ||
184 | DevFS has been obsoleted in favour of udev | |
e7b4311e | 185 | (https://www.kernel.org/pub/linux/utils/kernel/hotplug/) |
1da177e4 LT |
186 | |
187 | 32-bit UID support is now in place. Have fun! | |
188 | ||
189 | Linux documentation for functions is transitioning to inline | |
190 | documentation via specially-formatted comments near their | |
ff41c419 MCC |
191 | definitions in the source. These comments can be combined with ReST |
192 | files the Documentation/ directory to make enriched documentation, which can | |
193 | then be converted to PostScript, HTML, LaTex, ePUB and PDF files. | |
194 | In order to convert from ReST format to a format of your choice, you'll need | |
195 | Sphinx. | |
1da177e4 LT |
196 | |
197 | Util-linux | |
198 | ---------- | |
199 | ||
840f6690 | 200 | New versions of util-linux provide ``fdisk`` support for larger disks, |
1da177e4 LT |
201 | support new options to mount, recognize more supported partition |
202 | types, have a fdformat which works with 2.4 kernels, and similar goodies. | |
203 | You'll probably want to upgrade. | |
204 | ||
205 | Ksymoops | |
206 | -------- | |
207 | ||
62a07e6e JJ |
208 | If the unthinkable happens and your kernel oopses, you may need the |
209 | ksymoops tool to decode it, but in most cases you don't. | |
840f6690 | 210 | It is generally preferred to build the kernel with ``CONFIG_KALLSYMS`` so |
5adaf851 LT |
211 | that it produces readable dumps that can be used as-is (this also |
212 | produces better output than ksymoops). If for some reason your kernel | |
840f6690 | 213 | is not build with ``CONFIG_KALLSYMS`` and you have no way to rebuild and |
5adaf851 LT |
214 | reproduce the Oops with that option, then you can still decode that Oops |
215 | with ksymoops. | |
1da177e4 | 216 | |
1da177e4 LT |
217 | Mkinitrd |
218 | -------- | |
219 | ||
840f6690 | 220 | These changes to the ``/lib/modules`` file tree layout also require that |
1da177e4 LT |
221 | mkinitrd be upgraded. |
222 | ||
223 | E2fsprogs | |
224 | --------- | |
225 | ||
840f6690 | 226 | The latest version of ``e2fsprogs`` fixes several bugs in fsck and |
1da177e4 LT |
227 | debugfs. Obviously, it's a good idea to upgrade. |
228 | ||
229 | JFSutils | |
230 | -------- | |
231 | ||
840f6690 | 232 | The ``jfsutils`` package contains the utilities for the file system. |
1da177e4 | 233 | The following utilities are available: |
840f6690 MCC |
234 | |
235 | - ``fsck.jfs`` - initiate replay of the transaction log, and check | |
1da177e4 | 236 | and repair a JFS formatted partition. |
840f6690 MCC |
237 | |
238 | - ``mkfs.jfs`` - create a JFS formatted partition. | |
239 | ||
240 | - other file system utilities are also available in this package. | |
1da177e4 LT |
241 | |
242 | Reiserfsprogs | |
243 | ------------- | |
244 | ||
245 | The reiserfsprogs package should be used for reiserfs-3.6.x | |
246 | (Linux kernels 2.4.x). It is a combined package and contains working | |
840f6690 MCC |
247 | versions of ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` and |
248 | ``reiserfsck``. These utils work on both i386 and alpha platforms. | |
1da177e4 LT |
249 | |
250 | Xfsprogs | |
251 | -------- | |
252 | ||
840f6690 MCC |
253 | The latest version of ``xfsprogs`` contains ``mkfs.xfs``, ``xfs_db``, and the |
254 | ``xfs_repair`` utilities, among others, for the XFS filesystem. It is | |
1da177e4 LT |
255 | architecture independent and any version from 2.0.0 onward should |
256 | work correctly with this version of the XFS kernel code (2.6.0 or | |
257 | later is recommended, due to some significant improvements). | |
258 | ||
5085cb26 DB |
259 | PCMCIAutils |
260 | ----------- | |
261 | ||
840f6690 | 262 | PCMCIAutils replaces ``pcmcia-cs``. It properly sets up |
5085cb26 DB |
263 | PCMCIA sockets at system startup and loads the appropriate modules |
264 | for 16-bit PCMCIA devices if the kernel is modularized and the hotplug | |
265 | subsystem is used. | |
1da177e4 | 266 | |
1da177e4 LT |
267 | Quota-tools |
268 | ----------- | |
269 | ||
270 | Support for 32 bit uid's and gid's is required if you want to use | |
271 | the newer version 2 quota format. Quota-tools version 3.07 and | |
272 | newer has this support. Use the recommended version or newer | |
273 | from the table above. | |
274 | ||
275 | Intel IA32 microcode | |
276 | -------------------- | |
277 | ||
278 | A driver has been added to allow updating of Intel IA32 microcode, | |
890fbae2 | 279 | accessible as a normal (misc) character device. If you are not using |
1b49ecf2 | 280 | udev you may need to:: |
840f6690 MCC |
281 | |
282 | mkdir /dev/cpu | |
283 | mknod /dev/cpu/microcode c 10 184 | |
284 | chmod 0644 /dev/cpu/microcode | |
1da177e4 LT |
285 | |
286 | as root before you can use this. You'll probably also want to | |
287 | get the user-space microcode_ctl utility to use with this. | |
288 | ||
1da177e4 LT |
289 | udev |
290 | ---- | |
840f6690 MCC |
291 | |
292 | ``udev`` is a userspace application for populating ``/dev`` dynamically with | |
293 | only entries for devices actually present. ``udev`` replaces the basic | |
03a67a46 | 294 | functionality of devfs, while allowing persistent device naming for |
890fbae2 | 295 | devices. |
1da177e4 | 296 | |
909021ea MS |
297 | FUSE |
298 | ---- | |
299 | ||
300 | Needs libfuse 2.4.0 or later. Absolute minimum is 2.3.0 but mount | |
840f6690 | 301 | options ``direct_io`` and ``kernel_cache`` won't work. |
909021ea | 302 | |
1da177e4 | 303 | Networking |
840f6690 | 304 | ********** |
1da177e4 LT |
305 | |
306 | General changes | |
307 | --------------- | |
308 | ||
309 | If you have advanced network configuration needs, you should probably | |
310 | consider using the network tools from ip-route2. | |
311 | ||
312 | Packet Filter / NAT | |
313 | ------------------- | |
314 | The packet filtering and NAT code uses the same tools like the previous 2.4.x | |
315 | kernel series (iptables). It still includes backwards-compatibility modules | |
316 | for 2.2.x-style ipchains and 2.0.x-style ipfwadm. | |
317 | ||
318 | PPP | |
319 | --- | |
320 | ||
321 | The PPP driver has been restructured to support multilink and to | |
322 | enable it to operate over diverse media layers. If you use PPP, | |
323 | upgrade pppd to at least 2.4.0. | |
324 | ||
890fbae2 | 325 | If you are not using udev, you must have the device file /dev/ppp |
1b49ecf2 | 326 | which can be made by:: |
840f6690 MCC |
327 | |
328 | mknod /dev/ppp c 108 0 | |
1da177e4 LT |
329 | |
330 | as root. | |
331 | ||
1da177e4 LT |
332 | NFS-utils |
333 | --------- | |
334 | ||
5adaf851 LT |
335 | In ancient (2.4 and earlier) kernels, the nfs server needed to know |
336 | about any client that expected to be able to access files via NFS. This | |
840f6690 MCC |
337 | information would be given to the kernel by ``mountd`` when the client |
338 | mounted the filesystem, or by ``exportfs`` at system startup. exportfs | |
339 | would take information about active clients from ``/var/lib/nfs/rmtab``. | |
1da177e4 LT |
340 | |
341 | This approach is quite fragile as it depends on rmtab being correct | |
342 | which is not always easy, particularly when trying to implement | |
840f6690 | 343 | fail-over. Even when the system is working well, ``rmtab`` suffers from |
1da177e4 LT |
344 | getting lots of old entries that never get removed. |
345 | ||
5adaf851 LT |
346 | With modern kernels we have the option of having the kernel tell mountd |
347 | when it gets a request from an unknown host, and mountd can give | |
348 | appropriate export information to the kernel. This removes the | |
840f6690 | 349 | dependency on ``rmtab`` and means that the kernel only needs to know about |
5adaf851 | 350 | currently active clients. |
1da177e4 | 351 | |
1b49ecf2 | 352 | To enable this new functionality, you need to:: |
840f6690 | 353 | |
e4121712 | 354 | mount -t nfsd nfsd /proc/fs/nfsd |
1da177e4 LT |
355 | |
356 | before running exportfs or mountd. It is recommended that all NFS | |
357 | services be protected from the internet-at-large by a firewall where | |
358 | that is possible. | |
359 | ||
172d899d AK |
360 | mcelog |
361 | ------ | |
362 | ||
c8c3f7d6 | 363 | On x86 kernels the mcelog utility is needed to process and log machine check |
840f6690 MCC |
364 | events when ``CONFIG_X86_MCE`` is enabled. Machine check events are errors |
365 | reported by the CPU. Processing them is strongly encouraged. | |
