15: <h1>OpenBSD</h1>
16: <hr>
17: <h3>Changes Relative to other *BSD's.</h3>
18:
19: <p>
20: OpenBSD looks a lot like NetBSD (from which it is derived, following
21: the 4.4BSD roots), but is now being developed seperately. Good changes
22: from other free operating systems will be merged in (of course, depending
23: on various factors like developer time for example.) OpenBSD tracks
24: NetBSD changes very closely; say anywhere between 2 to 10 days
1.19 deraadt 25: behind the state of NetBSD-current all the time. You used to be able to
26: say that OpenBSD is NetBSD <b>PLUS MORE STUFF</b>, but nowadays OpenBSD
27: very much is it's own thing. Too much stuff was added and fixed to be
28: able to compare it against NetBSD...
1.14 deraadt 29:
30: <p>
31: Compared to NetBSD, various additions have been made. This is a
32: partial list of the major machine independent changes (ie. these are the
33: changes people ask about most often). Check the page of the specific port
34: you are interested in for further port-specific details. Note that many ports
35: have had architecture-specific enhancements.

1.17 deraadt 154: </ul>
155: <p>
156: <h3>OpenBSD 2.0 released.</h3>
157: <p>
1.15 deraadt 158: <ul>
1.14 deraadt 159: <li>The NIST Posix test suite became free. As a result we have been correcting
160: numerous problems in the source tree, and expect to be completely
161: POSIX compliant very soon.
162: <li>upgrade to CVS version 1.9.
163: <li>A number of security fixes to the way coredumping works.
164: <li>The /dev/*random devices are now default on all architectures.
165: <li>Add stack tracebacks to Arc port's kernel debugger.
166: <li>Skey revamped into full OTP (RFC1938) support, including sha1 and
167: md5 support.
168: <li>GPL i387 emulator added.
169: <li>Crank kvm space on the i386 port, also limit buffer cache useage
170: so that 512MB machines may work (untested :-)
171: <li>Numerous fixes to the lpr suite, including security.
172: <li>More ftpd raging paranoia security fixes.
173: <li>The NIST suite showed numerous errors in libraries and the kernel.
174: Only a few small errors remain now, mostly regarding serial
175: ports.
176: <li>In numerous utilities: prefer $LOGNAME, but also accept $USER.
177: <li>OLF binary type added. This is like ELF, but includes an OS-dependent
178: tag. elf2olf(1) converts an elf binary to a tagged OLF binary which
179: the kernel can recognize correctly.
180: <li>Beware $HOME overflows throughout the source tree.
181: <li>Integration of the pmax port.
182: <li>Import of ctm.
183: <li>Various repairs to the scsi scanner support.
184: <li>Numerous more difficult-to-exploit-but-possible-if-someone-really-wanted-to
185: buffer overflows found in system utilities..
186: <li>Memory leak paranoia in cron.
187: <li>Make login get more consistantly upset about failed logins, and tell user
188: about these failures at the next successfull login.
189: <li>pdksh version is now 5.2.11
190: <li>New bsd.*.mk feature: DEBUG=-g. Try it, you'll like it.
191: <li>The Arc port family has a new member: The rPC44 works!
192: <li>lpt driver is now bus-independent.
193: <li>com driver is now bus-independent.
194: <li>Numerous small security fixes again...
195: <li>Use pdksh as our /bin/sh. This provides excellent POSIX compliance.
196: <li>Prevent generic users from mounting filesystems by default.
197: <li>Added -C option to pax/tar. Also made -z support compressed files too.
198: <li>Increased compatibility in the pccons driver with BSDi features.
199: <li>Imported FreeBSD's calendar.
200: <li>GNU gdb works on the mips-based platforms.
201: <li>Add FreeBSD md5 diffs to mtree(8). This can be used to implement a
202: tripwire-like system.
203: <li>Some YP and bootparamd security changes.
204: <li>Hundreds of little fixes all over the place.
205: <li>Multiple updates for GNU software
206: <li>Add disklabels to the floppy device drivers.
207: <li>At boottime, have (*mountroot)() look at the root device's disklabel
208: to determine which filesystem type is to be mounted.
209: <li>If disklabel reading code discovers an ISOFS filesystem underlying,
210: spoof a nice disklabel (enough to fool mountroot).
211: <li>tcpdump 3.3
212: <li>Fix information gathering attack in ping(8).
213: <li>Add NetBSD's "route show" implementation, and at the samet time fix
214: the new buffer overflows that this provided.
215: <li>Fix a few setgroups() related security holes.
216: <li>sendmail 8.8.4
217: <li>texinfo 3.9
218: <li>f77 0.5.19
219: <li>Repair some more KerberosIV buffer overflows. Hard to believe this is
220: supposed to be security software.
221: <li>Add XCASE/IUCLC/OLCUC/OCRNL/ONOCR/ONLRET tty subsystem flags for
222: backwards compatibility.
223: <li>Permit NFS attribute cache to be configured on a per-mount basis.
224: <li>Properly split fsck, mount, and newfs into multiple pieces. Use
225: disklabel information if it is available.
226: <li>Add disklabels to the vnd device driver.
227: <li>Change the games to be run setgid games, not setuid games. This closes
228: a whole slew of fascinating security holes.
229: <li>Import of the powerpc port.
230: <li>Properly use _POSIX_SAVED_IDS throughout the source tree.
231: <li>Permit building of kernels without a.out support.
232: <li>ppp 2.3b3
233: <li>libcrypt goes away. We do not need this stub library anymore. Do not link
234: against it on OpenBSD, all the pieces you need are in libc.
1.18 deraadt 235: <li>new aucat command.
236: <li>Fix a fairly nasty security hole in all of the games.
1.20 downsj 237: <li>Support for the <a href="hp300.html">hp300</a> added.
238: <li>Upgrade of awk(1), integration of BSD tsort(1), getopt fixes.
239: <li>Sendmail upgraded to version 8.8.5.
1.21 downsj 240: <li>Added lchown(2) for compatibility with SVR4 implementations.
1.23 deraadt 241: <li>New gnu cpio 2.4.2
242: <li>Support lchown(2) in dump(8), cp(1), pax(1), cpio(1), chown(8), and
243: restore(8).
244: <li>No buffer lengths in fmt(1).
245: <li>various adjtime() corrections inside the kernel.
246: <li>Prevent stat() from disclosing inode generation numbers to non-root userland.
247: <li>pax in tar mode will understand multiple -v options to generate ls-like output.
248: <li>Repair many uses of the SIOCGIFCONF code for machines with an outrageous
249: number of network interfaces.
1.22 deraadt 250: <li>More kerberosIV security patches.
251: <li>A working fsirand.
252: <li>A start at a SA_SIGINFO implementation. Currently solid enough to provide
253: fault address information.
1.28 ! deraadt 254: <li>Completely in-tree <a href="ppc.html">PowerPC</a> port for non-Apple
! 255: hardware. This port requires nothing outside the in-tree development
! 256: environment to build (except mkisofs for building distributions).
! 257: <li>Some ypbind(8) tightening up, includes a method to specify a list of
! 258: valid servers
1.25 niklas 259: <li>Bug fixed that prevented bufpages/nbuf > 1 setups. This allows large
260: buffer caches even when available kvm space is low, like for i386
261: & sparc.
1.26 deraadt 262: <li>Changed netinet IP_HDRINCL option to require ip_len and ip_off in network
263: byte order. This is a compatibility/portability fix and we expect
264: other BSD systems to eventually follow suit.
265: <li>amd (the automounter) is now 64-bit and working on the alpha.
266: <li>The <a href="alpha.html">Alpha</a> port and all it's utilities now compiles
267: using in-tree versions of all tools. Yipee!
1.28 ! deraadt 268: <li>More work on the SA_SIGINFO implementation. (SA_SIGINFO is a small part of
1.27 deraadt 269: POSIX 1003.1b)
