68: <p>
69: This is a partial list of new features and systems included in OpenBSD 3.4.
70: For a comprehensive list, see the <a href="plus.html">changelog</a> leading
71: to 3.4.
72: <p>
73:
74: <ul>
75:
1.13 ! david 76: <li>The i386 architecture has been switched to the ELF executable format so
! 77: i386 upgrades are not possible for this release.
1.1 david 78: <p>
79:
1.6 tedu 80: <li>Further W^X improvements, including support for the i386 architecture.
81: Native i386 binaries have their executable segments rearranged to support
82: isolating code from data.
1.1 david 83: <p>
84:
1.6 tedu 85: <li>ld.so on ELF platforms now loads libraries in a random order for
86: greater resistance to attacks. The i386 architecture also has libraries
87: mapped at random addresses. Along with W^X, these changes increase the
88: difficulty of successfully exploiting an application error, such as a
89: buffer overflow.
1.1 david 90: <p>
91:
92: <li>A static bounds checker has been added to the compiler to perform basic
1.4 avsm 93: checks on functions which accept buffers and sizes. The checker aims to
1.8 david 94: find common mistakes in the use of library functions such as
1.4 avsm 95: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">strlcpy(3)</a>
96: or <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sscanf">sscanf(3)</a>
97: without emitting any false positives. Running it over the source and ports
98: trees revealed over a hundred real bugs, which were fixed and submitted back
99: to the original authors where possible.
1.1 david 100: <p>
101:
1.6 tedu 102: <li>Privilege separation has been implemented for the syslog daemon, making
103: it much more robust against future errors. The child which listens to
104: network traffic now runs as a normal user and chroots itself, while the
105: parent process tracks the state of the child and performs privileged
106: operations on its behalf.
1.1 david 107: <p>
108:
109: <li>Many unsafe string functions have been removed from the kernel and userland
1.6 tedu 110: utilities. This audit is one of the most comprehensive OpenBSD has ever
111: done, with thousands of occurrences of
1.12 deraadt 112: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcpy">strcpy(3)</a>,
113: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcat">strcat(3)</a>,
114: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sprintf">sprintf(3)</a>,
1.8 david 115: and
1.12 deraadt 116: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=vsprintf">vsprintf(3)</a>
1.4 avsm 117: being replaced with safer, bounded alternatives such as
1.12 deraadt 118: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">strlcpy(3)</a>,
119: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcat">strlcat(3)</a>,

1.1 david 124: <p>
125:
1.13 ! david 126: <li><a href="http://www.research.ibm.com/trl/projects/security/ssp/">
! 127: ProPolice</a> stack protection has been enabled in the kernel as well.
1.1 david 128: <p>
129:
130: <li>Manual pages have been greatly cleaned up and improved.
131: <p>
132:
1.8 david 133: <li>The ports tree now supports building programs under
134: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=systrace">
135: systrace(1)</a>, preventing the possibility of applications harming the
136: system at compile-time via trojaned configuration scripts or otherwise.
1.1 david 137: <p>
138:
1.3 jason 139: <li>More licenses fixes, including the removal of the advertising clause
1.6 tedu 140: for large parts of the source tree.
141: <p>
142:
1.11 deraadt 143: <li>Replacement of GNU diff/diff3, grep/egrep/fgrep/zgrep/zegrep/zfgrep,
144: and gzip/zcat/gunzip/gzcat/zcmp/zmore/zdiff/zforce/gzexe/znew
145: with BSD licensed equivalents.
1.6 tedu 146: <p>
147:
148: <li>Addition of read-only support for NTFS file systems.
149: <p>
150:
151: <li>Reliability improvements to layered file systems, enabling NULLFS to
152: work again.
153: <p>
154:
155: <li>Improvements to the linux emulator enabling more applications to run.
156: <p>
157:
1.13 ! david 158: <li>Legacy KerberosIV support has been removed, and the remaining KerberosV
! 159: codebase has been restructured for easier management.
1.3 jason 160: <p>
161:
1.13 ! david 162: <li>Over 2400 ports, 2200 pre-built packages.
1.1 david 163: <p>
164:
165: <li>A large number of bug fixes, changes, and optimizations to our packet filter
166: including:
167: <ul>
1.9 dhartmei 168: <li>packet tagging (e.g. filter on tags added by bridge based on MAC address)
1.10 frantzen 169: <li>stateful TCP normalization (prevent uptime calculation and NAT detection)
1.9 dhartmei 170: <li>passive OS detection (filter or redirect connections based on source OS)
171: <li>SYN proxy (protect servers against SYN flood attacks)
172: <li>adaptive state timeouts (prevent state table overflows under attack)
1.1 david 173: </ul>
174: <p>
175:
176: <li>The system includes the following major components from outside suppliers:
177: <ul>

210: Following this are the instructions which you would have on a piece of
211: paper if you had purchased a CDROM set instead of doing an alternate
212: form of install. The instructions for doing an ftp (or other style
213: of) install are very similar; the CDROM instructions are left intact

240: Quick installer information for people familiar with OpenBSD, and the
241: use of the "disklabel -E" command. If you are at all confused when
242: installing OpenBSD, read the relevant INSTALL.* file as listed above!
243: <p>
244:
245: <h3><font color="#e00000">OpenBSD/i386:</font></h3>
246: <ul>
247: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
248: release is on CD1. If your BIOS does not support booting from CD, you will need
249: to create a boot floppy to install from. To create a boot floppy write
250: <i>CD1:3.4/i386/floppy34.fs</i> to a floppy and boot via the floppy drive.
251:
252: <p>
253: Use <i>CD1:3.4/i386/floppyB34.fs</i> instead for greater scsi controller
254: support, or <i>CD1:3.4/i386/floppyC34.fs</i> for better laptop support.
255:
256: <p>
1.2 david 257: If you are planning on dual booting OpenBSD with another OS, you will need to
258: read the included INSTALL.i386 document.
1.1 david 259:
260: <p>
261: To make a boot floppy under MS-DOS, use the "rawrite" utility located
1.2 david 262: at <i>CD:/3.4/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
263: use the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=
264: dd&sektion=1">dd(1)</a> utility. The following is an example usage of
265: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)
266: </a>, where the device could be "floppy", "rfd0c", or
267: "rfd0a".

270: # <strong>dd if=<file> of=/dev/<device> bs=32k</strong>
271: </pre></ul>
272:
273: <p>
1.2 david 274: Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or
275: your install will most likely fail. For more information on creating a boot
276: floppy and installing OpenBSD/i386 please refer to

309:
310: <p>
311: If your sparc does not have a CD drive, you can alternatively boot from floppy.
1.2 david 312: To do so you need to write "CD3:3.4/sparc/floppy34.fs" to a floppy.
313: For more information see <a href="faq/faq4.html#MkFlop">FAQ4.1</a>. To boot from

449: read the <a href="ports.html">ports</a> page
450: if you know nothing about ports
451: at this point. This text is not a manual of how to use ports.
452: Rather, it is a set of notes meant to kickstart the user on the
453: OpenBSD ports system.
454: <p>
455: Certainly, the OpenBSD ports system is not complete. It is doubtful it
456: will ever be. However, it is growing very fast and getting more stable.
457: Almost all ports provided with this release should build without problems
458: on most architectures (over 2400 packages build on i386, for instance).
459: <p>
460: The <i>ports/</i> directory represents a CVS (see the manpage for
461: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=cvs&apropos=0&sektion=1&manpath=OpenBSD+Current&arch=i386&format=html">
462: cvs(1)</a> if
463: you aren't familiar with CVS) checkout of our ports. As with our complete
464: source tree, our ports tree is available via anoncvs. So, in
465: order to keep current with it, you must make the <i>ports/</i> tree
466: available on a read-write medium and update the tree with a command
467: like:
468: <p>
469: <ul><pre>
470: # <strong>cd [portsdir]/; cvs -d anoncvsserver.openbsd.org:/cvs update -Pd -rOPENBSD_3_4</strong>
471: </pre></ul>
472: <p>
473: [Of course, you must replace the local directory and server name here
474: with the location of your ports collection and a nearby anoncvs
475: server.]
476: <p>
477: Note that most ports are available as packages through ftp. Updated
478: packages for the 3.4 release will be made available if problems arise.
479: <p>
480: If you're interested in seeing a port added, would like to help out, or just
481: would like to know more, the mailing list ports@openbsd.org is a good
482: place to know.
