1.18 deraadt 54: For a comprehensive list, see the <a href="plus33.html">changelog</a> leading
1.1 miod 55: to 3.3.
56: <p>

58: <ul>
59: <li>Integration of the
1.30 david 60: <a href="http://www.research.ibm.com/trl/projects/security/ssp/">ProPolice</a>
1.26 deraadt 61: stack protection technology, by Hiroaki Etoh, into the system
62: compiler. This protection is enabled by default. With this change,
63: function prologues are modified to rearrange the stack: a random
64: canary is placed before the return address, and buffer variables are
65: moved closer to the canary so that regular variables are below, and
66: harder to smash. The function epilogue then checks if the canary is
67: still intact. If it is not, the process is terminated. This change
68: makes it very hard for an attacker to modify the return address used
69: when returning from a function.
1.2 deraadt 70: <p>
1.1 miod 71:
1.22 deraadt 72: <li>W^X (pronounced: "W xor X") on architectures capable of
1.10 deraadt 73: pure execute-bit support in the MMU (sparc, sparc64, alpha,
74: hppa). This is a fine-grained memory permissions layout, ensuring that
75: memory which can be written to by application programs can not be
1.22 deraadt 76: executable at the same time and vice versa. This raises the bar on
77: potential buffer overflows and other attacks: as a result, an attacker
78: is unable to write code anywhere in memory where it can be executed.
1.26 deraadt 79: (NOTE: i386 and powerpc do not support W^X in 3.3; however, 3.3-current
80: already supports it on i386, and both these processors are expected to
1.47 ! tb 81: support this change in 3.4).
1.1 miod 82: <p>
83:
1.2 deraadt 84: <li>Still more reduction in setuid and setgid binaries, and more chroot
1.22 deraadt 85: use throughout the system. While some programs are still setuid or
86: setgid, almost all of them grab a resource and then quickly revoke
87: privilege.
1.1 miod 88: <p>
89:
1.22 deraadt 90: <li>The X window server and xconsole now use privilege separation,
91: for better security. Also, xterm has been modified to do privilege
92: revocation. xdm runs as a special user and group, to further constrain
93: what might go wrong.
1.1 miod 94: <p>
95:
96: <li>As usual, improvements to the documentation, notably the man pages and
1.7 jsyn 97: the Web FAQ. An increasingly large part of the website is available in several
1.1 miod 98: languages.
99: <p>
100:
101: <li>More complete collection and better tested set of "ports".
102: setuid/setgid ports have been significantly reduced as well. Many of the
103: ones that remain setuid have been modified to revoke privileges as early
104: as possible.
105: <p>
106:
107: <li>Over 2000 pre-built and tested packages.
108: <p>
109:
110: <li>Significant improvements to the pthread library.
111: <p>
112:

114: our packet filter, <a

1.47 ! tb 119: <li>Anchors, allowing subrulesets which can be loaded and modified independently
1.17 deraadt 120: <li>Tables, a very efficient way for large address lists in rules
121: <li>Address pools, redirect/NAT to multiple addresses and thus load balancing

123: <li>TCP window scaling support
124: <li>Full CIDR support
125: <li>Early checksum verification return on invalid packets

1.22 deraadt 128: a spam deferral daemon, which SMTP connections can be redirected to.
129: This daemon handles connections based on black lists and white lists,
130: tar-pits the connections, and ensures that the spammer knows why their
131: mail has not been accepted.

210: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
211: release is on CD1. If your BIOS does not support booting from CD, you will need
212: to create a boot floppy to install from. To create a boot floppy write
213: <i>CD1:3.3/i386/floppy33.fs</i> to a floppy and boot via the floppy drive.
214:
215: <p>
216: Use <i>CD1:3.3/i386/floppyB33.fs</i> instead for greater scsi controller
217: support, or <i>CD1:3.3/i386/floppyC33.fs</i> for better laptop support.
218:
219: <p>
220: If you are planning on dual booting OpenBSD with another OS, you will need to read the included INSTALL.i386 document.
221:
222: <p>
223: To make a boot floppy under MS-DOS, use the "rawrite" utility located
1.46 sthen 224: at <i>CD:/3.3/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS, use the <a href="http://man.openbsd.org/?query=dd&sektion=1">dd(1)</a> utility. The following is an example usage of <a href="http://man.openbsd.org/?query=dd&sektion=1">dd(1)</a>, where the device could be "floppy", "rfd0c", or "rfd0a".

1.18 deraadt 264: 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.
