68: <p>
69: This is a partial list of new features and systems included in OpenBSD 3.3.
1.18 deraadt 70: For a comprehensive list, see the <a href="plus33.html">changelog</a> leading
1.1 miod 71: to 3.3.
72: <p>
73:
74: <ul>
75: <li>Integration of the
1.30 david 76: <a href="http://www.research.ibm.com/trl/projects/security/ssp/">ProPolice</a>
1.26 deraadt 77: stack protection technology, by Hiroaki Etoh, into the system
78: compiler. This protection is enabled by default. With this change,
79: function prologues are modified to rearrange the stack: a random
80: canary is placed before the return address, and buffer variables are
81: moved closer to the canary so that regular variables are below, and
82: harder to smash. The function epilogue then checks if the canary is
83: still intact. If it is not, the process is terminated. This change
84: makes it very hard for an attacker to modify the return address used
85: when returning from a function.
1.2 deraadt 86: <p>
1.1 miod 87:
1.22 deraadt 88: <li>W^X (pronounced: "W xor X") on architectures capable of
1.10 deraadt 89: pure execute-bit support in the MMU (sparc, sparc64, alpha,
90: hppa). This is a fine-grained memory permissions layout, ensuring that
91: memory which can be written to by application programs can not be
1.22 deraadt 92: executable at the same time and vice versa. This raises the bar on
93: potential buffer overflows and other attacks: as a result, an attacker
94: is unable to write code anywhere in memory where it can be executed.
1.26 deraadt 95: (NOTE: i386 and powerpc do not support W^X in 3.3; however, 3.3-current
96: already supports it on i386, and both these processors are expected to
97: support this change in 3.4).
1.1 miod 98: <p>
99:
1.2 deraadt 100: <li>Still more reduction in setuid and setgid binaries, and more chroot
1.22 deraadt 101: use throughout the system. While some programs are still setuid or
102: setgid, almost all of them grab a resource and then quickly revoke
103: privilege.
1.1 miod 104: <p>
105:
1.22 deraadt 106: <li>The X window server and xconsole now use privilege separation,
107: for better security. Also, xterm has been modified to do privilege
108: revocation. xdm runs as a special user and group, to further constrain
109: what might go wrong.
1.1 miod 110: <p>
111:
112: <li>As usual, improvements to the documentation, notably the man pages and
1.7 jsyn 113: the Web FAQ. An increasingly large part of the website is available in several
1.1 miod 114: languages.
115: <p>
116:
117: <li>More complete collection and better tested set of "ports".
118: setuid/setgid ports have been significantly reduced as well. Many of the
119: ones that remain setuid have been modified to revoke privileges as early
120: as possible.
121: <p>
122:
123: <li>Over 2000 pre-built and tested packages.
124: <p>
125:
126: <li>Significant improvements to the pthread library.
127: <p>
128:
129: <li>An incredible amount of enhancements and stability improvements to
130: our packet filter, <a
131: href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf&sektion=4">pf</a>,
1.8 henning 132: including:
1.1 miod 133: <ul>
1.17 deraadt 134: <li>Queue, a bandwidth management system (uses altq underneath)
135: <li>Anchors, allowing subrulesets which can be loaded and modified independently
136: <li>Tables, a very efficient way for large address lists in rules
137: <li>Address pools, redirect/NAT to multiple addresses and thus load balancing
138: <li>Configuration language has been made much more flexible
139: <li>TCP window scaling support
140: <li>Full CIDR support
141: <li>Early checksum verification return on invalid packets
142: <li>Performance boost: large rulesets load much faster now
1.22 deraadt 143: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=spamd">spamd</a>,
144: a spam deferral daemon, which SMTP connections can be redirected to.
145: This daemon handles connections based on black lists and white lists,
146: tar-pits the connections, and ensures that the spammer knows why their
147: mail has not been accepted.
1.1 miod 148: </ul>
1.11 jason 149:
150: <p>
151:
152: <li>Much improved <a href="sparc64.html">sparc64</a> support: support for

226: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
227: release is on CD1. If your BIOS does not support booting from CD, you will need
228: to create a boot floppy to install from. To create a boot floppy write
229: <i>CD1:3.3/i386/floppy33.fs</i> to a floppy and boot via the floppy drive.
230:
231: <p>
232: Use <i>CD1:3.3/i386/floppyB33.fs</i> instead for greater scsi controller
233: support, or <i>CD1:3.3/i386/floppyC33.fs</i> for better laptop support.
234:
235: <p>
236: If you are planning on dual booting OpenBSD with another OS, you will need to read the included INSTALL.i386 document.
237:
238: <p>
239: To make a boot floppy under MS-DOS, use the "rawrite" utility located
240: at <i>CD:/3.3/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS, use the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a> utility. The following is an example usage of <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>, where the device could be "floppy", "rfd0c", or "rfd0a".
