67: <h3><font color="#0000e0">What's New</font></h3>
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:
76: <li>The i386 architecture has been switched to the ELF executable format.
77: <p>
78:
1.6 tedu 79: <li>Further W^X improvements, including support for the i386 architecture.
80: Native i386 binaries have their executable segments rearranged to support
81: isolating code from data.
1.1 david 82: <p>
83:
1.6 tedu 84: <li>ld.so on ELF platforms now loads libraries in a random order for
85: greater resistance to attacks. The i386 architecture also has libraries
86: mapped at random addresses. Along with W^X, these changes increase the
87: difficulty of successfully exploiting an application error, such as a
88: buffer overflow.
1.1 david 89: <p>
90:
91: <li>A static bounds checker has been added to the compiler to perform basic
1.4 avsm 92: checks on functions which accept buffers and sizes. The checker aims to
1.8 david 93: find common mistakes in the use of library functions such as
1.4 avsm 94: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">strlcpy(3)</a>
95: or <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sscanf">sscanf(3)</a>
96: without emitting any false positives. Running it over the source and ports
97: trees revealed over a hundred real bugs, which were fixed and submitted back
98: to the original authors where possible.
1.1 david 99: <p>
100:
1.6 tedu 101: <li>Privilege separation has been implemented for the syslog daemon, making
102: it much more robust against future errors. The child which listens to
103: network traffic now runs as a normal user and chroots itself, while the
104: parent process tracks the state of the child and performs privileged
105: operations on its behalf.
1.1 david 106: <p>
107:
108: <li>Many unsafe string functions have been removed from the kernel and userland
1.6 tedu 109: utilities. This audit is one of the most comprehensive OpenBSD has ever
110: done, with thousands of occurrences of
1.8 david 111: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcpy">strcpy(3)</a>
112: and
113: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcat">strcat(3)</a>
1.4 avsm 114: being replaced with safer, bounded alternatives such as
1.8 david 115: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">
116: strlcpy(3)</a> and
117: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcat">
118: strlcat(3)</a>.
119:
1.1 david 120: <p>
121:
122: <li>Support for
123: <a href="http://www.research.ibm.com/trl/projects/security/ssp/">
124: ProPolice</a> stack protection in the kernel has been added.
125: <p>
126:
127: <li>Manual pages have been greatly cleaned up and improved.
128: <p>
129:
1.8 david 130: <li>The ports tree now supports building programs under
131: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=systrace">
132: systrace(1)</a>, preventing the possibility of applications harming the
133: system at compile-time via trojaned configuration scripts or otherwise.
1.1 david 134: <p>
135:
1.3 jason 136: <li>More licenses fixes, including the removal of the advertising clause
1.6 tedu 137: for large parts of the source tree.
138: <p>
139:
140: <li>Replacement of GNU diff, grep, and gzip with BSD licensed equivalents.
141: <p>
142:
143: <li>Addition of read-only support for NTFS file systems.
144: <p>
145:
146: <li>Reliability improvements to layered file systems, enabling NULLFS to
147: work again.
148: <p>
149:
150: <li>Improvements to the linux emulator enabling more applications to run.
151: <p>
152:
153: <li>Restructuring of Kerberos libraries for easier management.
1.3 jason 154: <p>
155:
1.1 david 156: <li>Over 2400 tested packages.
157: <p>
158:
159: <li>A large number of bug fixes, changes, and optimizations to our packet filter
160: including:
161: <ul>
1.9 ! dhartmei 162: <li>packet tagging (e.g. filter on tags added by bridge based on MAC address)
! 163: <li>stateful TCP normalization (reassemble tcp, normalize ttl and timeout)
! 164: <li>passive OS detection (filter or redirect connections based on source OS)
! 165: <li>SYN proxy (protect servers against SYN flood attacks)
! 166: <li>adaptive state timeouts (prevent state table overflows under attack)
1.1 david 167: </ul>
168: <p>
169:
170: <li>The system includes the following major components from outside suppliers:
171: <ul>
1.7 david 172: <li>XFree86 4.3.0 (+ patches, and i386 contains 3.3.X servers also, thus
173: providing support for all chipsets)

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

234: Quick installer information for people familiar with OpenBSD, and the
235: use of the "disklabel -E" command. If you are at all confused when
236: installing OpenBSD, read the relevant INSTALL.* file as listed above!
237: <p>
238:
239: <h3><font color="#e00000">OpenBSD/i386:</font></h3>
240: <ul>
241: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
242: release is on CD1. If your BIOS does not support booting from CD, you will need
243: to create a boot floppy to install from. To create a boot floppy write
244: <i>CD1:3.4/i386/floppy34.fs</i> to a floppy and boot via the floppy drive.
245:
246: <p>
247: Use <i>CD1:3.4/i386/floppyB34.fs</i> instead for greater scsi controller
248: support, or <i>CD1:3.4/i386/floppyC34.fs</i> for better laptop support.
249:
250: <p>
1.2 david 251: If you are planning on dual booting OpenBSD with another OS, you will need to
252: read the included INSTALL.i386 document.
1.1 david 253:
254: <p>
255: To make a boot floppy under MS-DOS, use the "rawrite" utility located
1.2 david 256: at <i>CD:/3.4/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
257: use the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=
258: dd&sektion=1">dd(1)</a> utility. The following is an example usage of
259: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)
260: </a>, where the device could be "floppy", "rfd0c", or
261: "rfd0a".

266:
267: <p>
1.2 david 268: Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or
269: your install will most likely fail. For more information on creating a boot
270: floppy and installing OpenBSD/i386 please refer to

303:
304: <p>
305: If your sparc does not have a CD drive, you can alternatively boot from floppy.
1.2 david 306: To do so you need to write "CD3:3.4/sparc/floppy34.fs" to a floppy.
307: For more information see <a href="faq/faq4.html#MkFlop">FAQ4.1</a>. To boot from

458: source tree, our ports tree is available via anoncvs. So, in
459: order to keep current with it, you must make the <i>ports/</i> tree
460: available on a read-write medium and update the tree with a command
461: like:
462: <p>
463: <ul><pre>
464: # <strong>cd [portsdir]/; cvs -d anoncvsserver.openbsd.org:/cvs update -Pd -rOPENBSD_3_4</strong>
465: </pre></ul>
466: <p>
467: [Of course, you must replace the local directory and server name here
468: with the location of your ports collection and a nearby anoncvs
469: server.]
470: <p>
471: Note that most ports are available as packages through ftp. Updated
472: packages for the 3.4 release will be made available if problems arise.
473: <p>
474: If you're interested in seeing a port added, would like to help out, or just
475: would like to know more, the mailing list ports@openbsd.org is a good
476: place to know.
