1.15 grr 23: <p>
24: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
25: tree up to date with respect to changes made to current OpenBSD sources.
1.14 downsj 26: <p>
1.15 grr 27: The major advantage of Anonymous CVS over other source code update
28: techniques is that it works directly against a central source code
29: repository or mirror. This means that you have the full set of CVS
30: commands available to control merging and updating your changes with
31: other source changes and for performing diff's, change histories
32: and other queries against the central repository.
1.36 deraadt 33: <p>
34: You can use anoncvs to access our three main source repositories:
35: <strong>src</strong>, <strong>ports</strong>, and <strong>www</strong>.
36: <p>
1.43 deraadt 37: <h3><font color=#0000e0>CVS:</font></h3>
1.36 deraadt 38: <a href=why-cvs.html>
39: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16 deraadt 40: It implements a central repository for all officially released source code
1.15 grr 41: and changes, while permitting developers to maintain local copies of the
42: source code with their working changes. Developers with "write access"
43: can commit changes directly to the OpenBSD source tree, while "Anonymous
44: CVS" users have "read access" and can keep their local copies of the source
45: up to date and issue queries against the central depository.
46: <p>
1.22 niklas 47: The major strength of CVS is that it has the ability to perform intelligent
1.15 grr 48: merges of changes to the central repository with changes that you make to
49: your local copy. This means that if you make a change to a module and
50: perform an update, your changes are not "blown away", rather CVS makes
51: best efforts to merge the changes made to the central sources with changes
52: you've made to your local copy.
53: <p>
54: In the event that the changes can't be completely merged, CVS provides a
55: "soft fallback", in terms of providing you with annotated changes to your
1.39 todd 56: local copy, preserving an unmodified copy of your version and continuing
1.15 grr 57: to update any other source modules you requested.
1.22 niklas 58: <p>
1.23 mickey 59: People who own an OpenBSD CD may have seen the CVS/ dirs on it.
1.22 niklas 60: Actually there is a reason, the CD has a checkout of the OpenBSD src/ module
1.23 mickey 61: usable to continue updating from. Using this tree will results in a much
62: faster initial CVS update than a fresh checkout of the full OpenBSD
63: source tree. There are two ways of using the CD:
64: <ul>
65: <li>copy the tree off it, (assuming the CD is mounted on /mnt):
1.22 niklas 66: <pre>
1.23 mickey 67: <b>#</b> cd /mnt; cp -Rp CVS Makefile bin distrib etc games gnu \
68: <b>></b> include kerberosIV lib libexec lkm regress sbin share \
69: <b>></b> sys usr.bin usr.sbin /usr/src
1.22 niklas 70: </pre>
1.23 mickey 71: <li>use a union mount with the CD below a writable directory.
1.22 niklas 72: <pre>
1.23 mickey 73: <b>#</b> mount -t union -o -b /mnt /usr/src
1.22 niklas 74: </pre>
1.23 mickey 75: </ul>
1.22 niklas 76: After this, /usr/src will be a nice checkout area where all cvs(1) commands
77: will work OK.

1.27 todd 79: <dt> cvs [cvs args] [cvs command] [cvs command args]
80: <dd> below is a listing of commonly used cvs commands.
1.15 grr 81: <dl>
82: <DT>add
83: <dd>Add a new file or directory to the repository.
84: <dt>get
85: <dd>Make a working directory of source files for editing.

94: <dt>rdiff
95: <dd>Prepare a collection of diffs reflecting changes between release.
96: <dt>status

1.1 deraadt 101: <p>
1.39 todd 102: To summarize, the real strength of using Anonymous CVS is that it is
1.15 grr 103: a "tolerant" source code control system - it <strong>respects</strong>
104: changes that you have made to your local sources and makes <strong>
105: "best efforts"</strong> to update your entire source tree, rather than
106: leaving you a list of arcane problems that have to be resolved before
107: continuing.

1.43 deraadt 109: <h3><font color=#0000e0>Using Anonymous CVS:</font></h3>
1.1 deraadt 110: <p>
111: The latest version of CVS is available at
1.47 pauls 112: <a href=http://download.cyclic.com/pub/>Cyclic</a>.
1.1 deraadt 113: Versions earlier than 1.6 are not recommended, and may not work.
114: If you already have OpenBSD installed, CVS is included.
115:
116: <p>
117: There are two levels of source tree access:
118:
119: <dl>
120: <dt><strong>Read-write access for developers:</strong>
121: <dd>Developers who need to commit changes to the source tree must have
122: an account on the OpenBSD machines. Getting this access will be a
123: natural result of working on the sources with other OpenBSD developers.
124: If someone does some good work and shows they can work with the team,
125: they will get an account.
126: </dl>
127:
128: <dl>
129: <dt><strong>Read-only access for everyone:</strong>
130: <dd>Anyone can access the read-only CVS repositories. These copies
131: of the read-write CVS repository are mirrored often. To use one,
132: set your <strong>CVSROOT</strong> environment variable to one of
133: the following values:

280: <strong>IMPORTANT NOTE:</strong>
281: There are a few issues relating to cryptographic software that everyone

283: <ul>
284: <li>The OpenBSD sources are from Canada.
1.9 deraadt 285: As
286: <a href=http://insight.mcmaster.ca/org/efc/pages/doc/crypto-export.html>
287: researched by a Canadian individual</a>
288: and as
289: <a href=http://axion.physics.ubc.ca/ECL.html>
290: described in the Export Control list of Canada</a>
291: is legal to export crypto software from Canada to the world.
1.1 deraadt 292: <p>
293: <li>However, if you are outside the USA or Canada, you should not
294: fetch the cryptographic sections of the OpenBSD sources from an
295: anoncvs server located in the USA. The files in question are...
296: <ul>
297: <li>src/kerberosIV/*
1.57 art 298: <li>src/lib/libdes/*
1.1 deraadt 299: <li>src/lib/libc/crypt/crypt.c

1.56 matthieu 303: <li>X11/xc/lib/Xdmcp/Wraphelp.c
1.1 deraadt 304: </ul>
305: Because of the USA ITAR munitions list,

309: on to find out how you can help.
310: </ul>
311:
312: <p>
313: A sample use of an anoncvs CVS server would be:
1.27 todd 314: <ul>
1.1 deraadt 315: <pre>
1.59 beck 316: % setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs

1.1 deraadt 322: % cvs diff -bc -r1.1 -r1.5 src/sys/arch/sparc/sparc/locore.s
1.12 grr 323: [shows the changes between revisions 1.1 and rev 1.5]
1.1 deraadt 324: </pre>
1.27 todd 325: </ul>
1.1 deraadt 326:
327: <p>
1.18 todd 328: <a name=pserver>In order to use a cvs ``pserver'' (a direct tcp connection instead of using ssh or rsh) you must login once:</a>
329: <pre>
330: [ *NOTE* You must be using cvs version 1.8 or higher to do this ]
1.59 beck 331: % setenv CVSROOT :pserver:anoncvs@anoncvs.ca.openbsd.org:/cvs
1.18 todd 332: % cvs login
1.59 beck 333: (Logging in to anoncvs@anoncvs1.ca.openbsd.org)
1.71 millert 334: CVS password: anoncvs

342: [ -z9 allows gzip -9 compression, GOOD medicine for slow links ]
343: </pre>
344:
345: <p>
1.39 todd 346: Here is how someone using anoncvs regularly would update his
1.1 deraadt 347: source tree:
1.60 millert 348: <ul><li>First, start out by `get'-ing an initial tree:
1.27 todd 349:
1.1 deraadt 350: <pre>
1.59 beck 351: # setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs
1.1 deraadt 352: # cd /usr
353: # cvs -q get -PA src
354: </pre>
1.27 todd 355: </li>
1.37 todd 356:
1.27 todd 357: <li> Anytime afterwards, to `update' this tree:
1.1 deraadt 358: <pre>
1.41 deraadt 359: # cd /usr/src
360: # cvs -q up -PAd
1.1 deraadt 361: </pre>
1.27 todd 362:
1.39 todd 363: Everytime you ran this it would synchronize your /usr/src tree. It would
1.1 deraadt 364: not destroy any of your local changes, rather it would attempt to merge
365: changes in. If you use obj directories (not obj symbolic links) you may
366: wish to append "-I obj" to the cvs command line, this will keep cvs from
367: spitting out a warning about all the obj directories it is going to
368: encounter which are not in the repository.
1.72 millert 369:
370: <p>
371: <li> NOTE: if you are updating a source tree that you initially fetched
372: from a different server, or from a CD, you <strong>must</strong>
373: add the <em>-d $CVSROOT</em> options to cvs. You must also set the
374: <em>CVS_IGNORE_REMOTE_ROOT</em> environment variable.
375:
376: <pre>
377: # cd /usr/src
378: # cvs -d $CVSROOT -q up -PAd
379: </pre>
380:
1.27 todd 381: </li>
382: </ul>
383:
1.37 todd 384: <p>
385: To <a name=ports>use</a> <a href=ports.html>ports</a>, it is similar to src:
386: <ul><li>
387: <pre>
1.59 beck 388: # setenv CVSROOT anoncvs@anoncvs.ca.openbsd.org:/cvs
1.37 todd 389: # cd /usr
390: # cvs -q get -PA ports
1.38 deraadt 391: </pre>

1.12 grr 420: <strong>Warning:</strong>
421: When using cvs you should take care that your current directory is either
422: the root of the tree you're referencing or in a separate place such as /tmp.
423: Some commands such as "get" can create an arbitrary sub-tree in the current
424: directory, and a subsequent update will recursively flesh out this sub-tree.

426: <p>
1.1 deraadt 427: The anoncvs service gives fledgling developers a chance to learn CVS
428: operation and get thoroughly involved in the development process
429: before getting "commit" access -- as a result of showing useful
430: skills and high quality results they will naturally later be given
431: developer access. As well, people providing patches can create
432: their "diff"s relative to the CVS tree, which will ease integration.

1.15 grr 435: <strong>Anoncvs: rsh vs. ssh</strong>
1.12 grr 436: <br>
437: By default, the CVS client uses rsh to talk to the CVS server. Many
1.39 todd 438: of the CVS sites no longer support rsh for security reasons or a local
1.12 grr 439: problem like a firewall or imperfect protocol emulator such as slirp
440: may prevent you from using rsh.
441: The alternative is a to use a "secure shell" connection using
1.48 ryker 442: <a href=http://www.cs.hut.fi/ssh/>ssh</a>. This is a commercial product
1.12 grr 443: offered by <a href=http://www.ssh.fi>SSH Communications Security Ltd</a>,
444: however they make a free unix version available that can be easily
1.68 wvdputte 445: installed under OpenBSD. Make sure you read the LICENSING doc! If you have
446: installed the OpenBSD <A HREF="ports.html">ports tree</A> you can download,
447: compile, and install the free UNIX version just by changing directory into the
448: directory /usr/ports/security/ssh and typing <KBD>make install</KBD>.
449: If you installed "ports" from the OpenBSD 2.4 CD-ROM, you get ssh
450: version 1.2.26 and should eventually "cvs update ports" and rebuild it as above
1.49 ian 451: after you get ssh and anoncvs working, to get the latest version.
1.68 wvdputte 452: Alternately, you can manually download the latest 1.2.* Unix version from
453: <a href= "ftp://ftp.funet.fi/pub/unix/security/login/ssh/">
454: ftp://ftp.funet.fi/pub/unix/security/login/ssh/</a> or
455: <a href= "http://www.datafellows.com/f-secure/fnetsys.htm">
456: http://www.datafellows.com/f-secure/fnetsys.htm</a>,
457: compile, and install it yourself.
458:
459: <p>
460: The OpenBSD anoncvs repositries support the SSH1 protocol, not the SSH2 protocol
461: due to the use of a "strict non-commercial use licensing policy".
1.28 beck 462:
1.75 millert 463: <p>
464: Once ssh is installed, one sets the environment variable
1.28 beck 465: <strong>CVS_RSH</strong> to point to ssh (typically
466: <strong>/usr/local/bin/ssh</strong>). If your local site prevents you
467: from connecting out to port 22 (which ssh defaults to using) use port
468: 2022.
1.1 deraadt 469:
470: <p>
471: Do not be tempted to turn on compression since CVS already compresses.
472: Use something like the following in your <strong>$HOME/.ssh/config</strong>
1.10 millert 473: file. Note that not all anoncvs servers allow ssh connections on
1.21 millert 474: port 2022. Also note that most anoncvs servers no longer accept
475: the <strong>none</strong> cipher as it is disabled in recent
476: versions of ssh for security reasons.

1.65 matthieu 499: <p><strong>X11 Source tree</strong>
500: <br>
501: Anoncvs mirrors also carry the OpenBSD X11 source tree. You can adapt
502: the recipe above to update your X11 source tree from the second CD.
503: Either copy or use a union mount to get the X11 sources in /usr/X11:
504: <ul>
505: <li>copy the tree off it (assuming the 2nd CD is mounted on /mnt):
506: <pre>
507: <b>#</b> cd /mnt; cp -Rp X11 /usr
508: </pre>
509: <li>use a union mount with the CD below a writable directory.
510: <pre>
511: <b>#</b> mount -t union -o -b /mnt/X11 /usr/X11
512: </pre>
513: </ul>
514: After this, /usr/X11 will be ready to be used by cvs. You can for
515: example update it to -current source (assuming you've already set
516: the <b>CVSROOT</b> environment variable):
517: <pre>
518: <b>#</b> cd /usr/X11
519: <b>#</b> cvs -q update -PAd
520: </pre>

522: <p><strong>Setting up a new anoncvs mirror</strong>
523: <br>
1.1 deraadt 524: If you wish to be a new anoncvs mirror site, please contact the anoncvs
525: <a href=mailto:deraadt@theos.com>maintainer</a>.
1.30 beck 526: Anoncvs mirrors require about 500MB of disk, and use up to 4MB of swap
1.1 deraadt 527: per anoncvs user (assuming the user does a large operation; while smaller
528: operations use fewer resources, anoncvs still makes much more of an
529: impact than ftp or sup). Such anoncvs machines should have excellent
530: network connectivity for the area they are expected to serve. A
531: <a href=anoncvs.shar>document</a>
532: which describes the setup of anoncvs servers is available.
533:
1.60 millert 534: <h3><font color=#0000e0>Final notes:</font></h3>
535: After upgrading your source tree, you should read the comments
536: at the top of <KBD>/usr/src/Makefile</KBD> before attemping
537: a build. Also, you should build a new kernel <strong>before</strong>
538: doing a <KBD>make build</KBD> if possible. In some cases it make be
539: necessary to rebuild and install the <KBD>config</KBD> utility before
540: you can build the kernel. If <KBD>config GENERIC</KBD> fails this
541: is probably the case.
542: <p>
543: It is important to note that upgrading from a release to the current tree
544: by rebuilding the sources can be rather difficult due to dependencies
545: that are often not obvious. Therefore, it is suggested that you first
546: install the latest snapshot before attemping a tree build from source.
