55: <h3><font color="#0000e0">What's New</font></h3>
56: <p>
57: This is a partial list of new features and systems included in OpenBSD 3.3.
1.18 deraadt 58: For a comprehensive list, see the <a href="plus33.html">changelog</a> leading
1.1 miod 59: to 3.3.
60: <p>
61:
62: <ul>
63: <li>Integration of the
1.30 david 64: <a href="http://www.research.ibm.com/trl/projects/security/ssp/">ProPolice</a>
1.26 deraadt 65: stack protection technology, by Hiroaki Etoh, into the system
66: compiler. This protection is enabled by default. With this change,
67: function prologues are modified to rearrange the stack: a random
68: canary is placed before the return address, and buffer variables are
69: moved closer to the canary so that regular variables are below, and
70: harder to smash. The function epilogue then checks if the canary is
71: still intact. If it is not, the process is terminated. This change
72: makes it very hard for an attacker to modify the return address used
73: when returning from a function.
1.2 deraadt 74: <p>
1.1 miod 75:
1.22 deraadt 76: <li>W^X (pronounced: "W xor X") on architectures capable of
1.10 deraadt 77: pure execute-bit support in the MMU (sparc, sparc64, alpha,
78: hppa). This is a fine-grained memory permissions layout, ensuring that
79: memory which can be written to by application programs can not be
1.22 deraadt 80: executable at the same time and vice versa. This raises the bar on
81: potential buffer overflows and other attacks: as a result, an attacker
82: is unable to write code anywhere in memory where it can be executed.
1.26 deraadt 83: (NOTE: i386 and powerpc do not support W^X in 3.3; however, 3.3-current
84: already supports it on i386, and both these processors are expected to
85: support this change in 3.4).
1.1 miod 86: <p>
87:
1.2 deraadt 88: <li>Still more reduction in setuid and setgid binaries, and more chroot
1.22 deraadt 89: use throughout the system. While some programs are still setuid or
90: setgid, almost all of them grab a resource and then quickly revoke
91: privilege.
1.1 miod 92: <p>
93:
1.22 deraadt 94: <li>The X window server and xconsole now use privilege separation,
95: for better security. Also, xterm has been modified to do privilege
96: revocation. xdm runs as a special user and group, to further constrain
97: what might go wrong.
1.1 miod 98: <p>
99:
100: <li>As usual, improvements to the documentation, notably the man pages and
1.7 jsyn 101: the Web FAQ. An increasingly large part of the website is available in several
1.1 miod 102: languages.
103: <p>
104:
105: <li>More complete collection and better tested set of "ports".
106: setuid/setgid ports have been significantly reduced as well. Many of the
107: ones that remain setuid have been modified to revoke privileges as early
108: as possible.
109: <p>
110:
111: <li>Over 2000 pre-built and tested packages.
112: <p>
113:
114: <li>Significant improvements to the pthread library.
115: <p>
116:
117: <li>An incredible amount of enhancements and stability improvements to
118: our packet filter, <a
119: href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf&sektion=4">pf</a>,
1.8 henning 120: including:
1.1 miod 121: <ul>
1.17 deraadt 122: <li>Queue, a bandwidth management system (uses altq underneath)
123: <li>Anchors, allowing subrulesets which can be loaded and modified independently
124: <li>Tables, a very efficient way for large address lists in rules
125: <li>Address pools, redirect/NAT to multiple addresses and thus load balancing
126: <li>Configuration language has been made much more flexible
127: <li>TCP window scaling support
128: <li>Full CIDR support
129: <li>Early checksum verification return on invalid packets
130: <li>Performance boost: large rulesets load much faster now
1.22 deraadt 131: <li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=spamd">spamd</a>,
132: a spam deferral daemon, which SMTP connections can be redirected to.
133: This daemon handles connections based on black lists and white lists,
134: tar-pits the connections, and ensures that the spammer knows why their
135: mail has not been accepted.
1.1 miod 136: </ul>
1.11 jason 137:
138: <p>
139:
140: <li>Much improved <a href="sparc64.html">sparc64</a> support: support for

214: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
215: release is on CD1. If your BIOS does not support booting from CD, you will need
216: to create a boot floppy to install from. To create a boot floppy write
217: <i>CD1:3.3/i386/floppy33.fs</i> to a floppy and boot via the floppy drive.
218:
219: <p>
220: Use <i>CD1:3.3/i386/floppyB33.fs</i> instead for greater scsi controller
221: support, or <i>CD1:3.3/i386/floppyC33.fs</i> for better laptop support.
222:
223: <p>
224: If you are planning on dual booting OpenBSD with another OS, you will need to read the included INSTALL.i386 document.
225:
226: <p>
227: To make a boot floppy under MS-DOS, use the "rawrite" utility located
228: 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".

267: If your sparc does not have a CD drive, you can alternatively boot from floppy.
1.18 deraadt 268: To do so you need to write "CD3:3.3/sparc/floppy33.fs" to a floppy. For more information see <a href="faq/faq4.html#MkFlop">FAQ4.1</a>. To boot from the floppy use one of the two commands listed below, depending on the version of your ROM.
