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:
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
1.14 ! deraadt 82: isolating code from data, and the cpu CS limit is used to impose a best
! 83: effort limit on code execution.
1.1 david 84: <p>
85:
1.6 tedu 86: <li>ld.so on ELF platforms now loads libraries in a random order for
1.14 ! deraadt 87: greater resistance to attacks. The i386 architecture also maps libraries
! 88: somewhat randomized addresses. Together with W^X and ProPolice, these
! 89: changes increase the difficulty of successfully exploiting an application
! 90: error, such as a buffer overflow.
1.1 david 91: <p>
92:
93: <li>A static bounds checker has been added to the compiler to perform basic
1.4 avsm 94: checks on functions which accept buffers and sizes. The checker aims to
1.8 david 95: find common mistakes in the use of library functions such as
1.4 avsm 96: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">strlcpy(3)</a>
97: or <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sscanf">sscanf(3)</a>
98: without emitting any false positives. Running it over the source and ports
99: trees revealed over a hundred real bugs, which were fixed and submitted back
100: to the original authors where possible.
1.1 david 101: <p>
102:
1.6 tedu 103: <li>Privilege separation has been implemented for the syslog daemon, making
104: it much more robust against future errors. The child which listens to
105: network traffic now runs as a normal user and chroots itself, while the
106: parent process tracks the state of the child and performs privileged
107: operations on its behalf.
1.1 david 108: <p>
109:
110: <li>Many unsafe string functions have been removed from the kernel and userland
1.6 tedu 111: utilities. This audit is one of the most comprehensive OpenBSD has ever
112: done, with thousands of occurrences of
1.12 deraadt 113: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcpy">strcpy(3)</a>,
114: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strcat">strcat(3)</a>,
115: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sprintf">sprintf(3)</a>,
1.8 david 116: and
1.12 deraadt 117: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=vsprintf">vsprintf(3)</a>
1.4 avsm 118: being replaced with safer, bounded alternatives such as
1.12 deraadt 119: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcpy">strlcpy(3)</a>,
120: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=strlcat">strlcat(3)</a>,
121: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=snprintf">snprintf(3)</a>,
122: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=vsnprintf">vsnprintf(3)</a>,
123: and
124: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=asprintf">asprintf(3)</a>.
1.1 david 125: <p>
126:
1.13 david 127: <li><a href="http://www.research.ibm.com/trl/projects/security/ssp/">
128: ProPolice</a> stack protection has been enabled in the kernel as well.
1.1 david 129: <p>
130:
131: <li>Manual pages have been greatly cleaned up and improved.
132: <p>
133:
1.8 david 134: <li>The ports tree now supports building programs under
135: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=systrace">
136: systrace(1)</a>, preventing the possibility of applications harming the
137: system at compile-time via trojaned configuration scripts or otherwise.
1.1 david 138: <p>
139:
1.3 jason 140: <li>More licenses fixes, including the removal of the advertising clause
1.6 tedu 141: for large parts of the source tree.
142: <p>
143:
1.11 deraadt 144: <li>Replacement of GNU diff/diff3, grep/egrep/fgrep/zgrep/zegrep/zfgrep,
145: and gzip/zcat/gunzip/gzcat/zcmp/zmore/zdiff/zforce/gzexe/znew
146: with BSD licensed equivalents.
1.6 tedu 147: <p>
148:
149: <li>Addition of read-only support for NTFS file systems.
150: <p>
151:
152: <li>Reliability improvements to layered file systems, enabling NULLFS to
153: work again.
154: <p>
155:
156: <li>Improvements to the linux emulator enabling more applications to run.
157: <p>
158:
1.13 david 159: <li>Legacy KerberosIV support has been removed, and the remaining KerberosV
160: codebase has been restructured for easier management.
1.3 jason 161: <p>
162:
1.13 david 163: <li>Over 2400 ports, 2200 pre-built packages.
1.1 david 164: <p>
165:
166: <li>A large number of bug fixes, changes, and optimizations to our packet filter
167: including:
168: <ul>
1.9 dhartmei 169: <li>packet tagging (e.g. filter on tags added by bridge based on MAC address)
1.10 frantzen 170: <li>stateful TCP normalization (prevent uptime calculation and NAT detection)
1.9 dhartmei 171: <li>passive OS detection (filter or redirect connections based on source OS)
172: <li>SYN proxy (protect servers against SYN flood attacks)
173: <li>adaptive state timeouts (prevent state table overflows under attack)
1.1 david 174: </ul>
175: <p>
176:
177: <li>The system includes the following major components from outside suppliers:
178: <ul>
1.7 david 179: <li>XFree86 4.3.0 (+ patches, and i386 contains 3.3.X servers also, thus

210: <p>
211: Following this are the instructions which you would have on a piece of
212: paper if you had purchased a CDROM set instead of doing an alternate
213: form of install. The instructions for doing an ftp (or other style
214: of) install are very similar; the CDROM instructions are left intact
215: so that you can see how much easier it would have been if you had
216: purchased a CDROM instead.
217: <p>

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

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

310:
311: <p>
312: If your sparc does not have a CD drive, you can alternatively boot from floppy.
1.2 david 313: To do so you need to write "CD3:3.4/sparc/floppy34.fs" to a floppy.

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