! 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
! 25: behind the state of NetBSD-current all the time. Hence you can truly
! 26: say that OpenBSD is NetBSD <b>PLUS MORE STUFF</b>.
! 27:
! 28: <p>
! 29: Compared to NetBSD, various additions have been made. This is a
! 30: partial list of the major machine independent changes (ie. these are the
! 31: changes people ask about most often). Check the page of the specific port
! 32: you are interested in for further port-specific details. Note that many ports
! 33: have had architecture-specific enhancements.
! 34:
! 35: <ul>
! 36: <li>Many many NetBSD PR's fixed (which NetBSD has not yet fixed)
! 37: <li>New curses library, including libform, libpanel and libmenu.
! 38: <li>a termlib library which understands termcap.db, needed for new curses.
! 39: <li>The FreeBSD ports subsystem was integrated and is usable by you!
! 40: <li>ipfilter for filtering dangerous packets
! 41: <li>better ELF support
! 42: <li>nlist() that understands ELF, ECOFF, and a.out, allowing non-a.out ports
! 43: to use kvm utilies
! 44: <li>Verbatim integration of the GNU tools (using a wrapper Makefile)
! 45: <li>All the pieces needed for cross compilation are in the source tree.
! 46: <li>Some LKM support in the tree.
! 47: <li>ATAPI support (should work on all ISA busses)
! 48: <li>new scsi, md5, pkg_* commands
! 49: <li>Numerous security related fixes
! 50: <li>Kerberos and other crypto in the source tree that is exportable
! 51: <li>Solid YP master, server, and client capabilities.
! 52: <li>/dev/*random -- a device driver providing some kinds of random data
! 53: <li>In-kernel update(8) with an adaptive algorithm
! 54: <li>Some ddb improvements and extensions
! 55: <li>Numerous scsi fixes
! 56: <li>ncheck utility for ffs
! 57: <li>/sbin/init now deals with non-existant ttys, no longer spins gettys madly.
! 58: <li>new system calls: rfork(), minherit(), poll().
! 59: <li>select() that can handle any amount of file descriptors.
! 60: <li>kernfs extensions
! 61: <li>ATM support (support for one company's sparc & i386 cards available)
! 62: <li>Boot kernels with "-c" to edit/enable/disable device configuration tables
! 63: <li>pax as tar, gnutar is toast
! 64: <li>using AT&T awk, gawk is toast
! 65: <li>Even more security fixes.

! 67: generate them too
! 68: <li>Linux ext2fs and BSD4.4 LFS support being worked on.
! 69: <li>Working ATAPI audio support for multiple architectures.
! 70: <li>terminfo database support.
! 71: <li>Fortran in the tree.
! 72: <li>The most secure rdist support anywhere.
! 73: <li>randomized port allocation in bind(), bindresvport(), and rresvport() --
! 74: security via unpredictability.
! 75: <li>Protection from the udp spamming and ftp bounce attacks.
! 76: <li>Significantly improved ftp daemon.

! 117: out+dial
! 118: <li>DDcess symrom LKM es
! 119: <li>Say goodbye to dump, restore, and mt security holes: They are no longer
! 120: setuid.

! 126: restore, mt).
! 127: <li>vim is replacing nvi, since nvi does not have a pure BSD license, and vim
! 128: also works better.
! 129: <li>16 partitions working on sparc and i386 (yipee!)
! 130: <li>Nice sample files in /etc
! 131: <li>sendmail gecos hole fixed (in a number of ways; other programs in the

! 141: <li>A 7% reduction in size of static binaries.
! 142: <li>FreeBSD's adduser(8) command. Also an rmuser(8) command.
! 143: <li>We have completed security reviews of almost all userland programs and
! 144: libraries except for the gnu stuff (where, based on preliminary
! 145: inspection there is poor handling of temp files).
! 146: <li>Working Linux ext2fs.
! 147: <li>Added sudo (which is maintained by one of our developers)
! 148: <li>CTM is now a supported way of obtaining OpenBSD source code.
! 149: <li>The NIST Posix test suite became free. As a result we have been correcting
! 150: numerous problems in the source tree, and expect to be completely
! 151: POSIX compliant very soon.
! 152: <li>upgrade to CVS version 1.9.
! 153: <li>A number of security fixes to the way coredumping works.

! 161: <li>Numerous fixes to the lpr suite, including security.
! 162: <li>More ftpd raging paranoia security fixes.

! 164: Only a few small errors remain now, mostly regarding serial
! 165: ports.
! 166: <li>In numerous utilities: prefer $LOGNAME, but also accept $USER.
! 167: <li>OLF binary type added. This is like ELF, but includes an OS-dependent
! 168: tag. elf2olf(1) converts an elf binary to a tagged OLF binary which
! 169: the kernel can recognize correctly.
! 170: <li>Beware $HOME overflows throughout the source tree.
! 171: <li>Integration of the pmax port.
! 172: <li>Import of ctm.
! 173: <li>Various repairs to the scsi scanner support.
! 174: <li>Numerous more difficult-to-exploit-but-possible-if-someone-really-wanted-to
! 175: buffer overflows found in system utilities..
! 176: <li>Memory leak paranoia in cron.

! 183: <li>com driver is now bus-independent.
! 184: <li>Numerous small security fixes again...
! 185: <li>Use pdksh as our /bin/sh. This provides excellent POSIX compliance.
! 186: <li>Prevent generic users from mounting filesystems by default.
! 187: <li>Added -C option to pax/tar. Also made -z support compressed files too.
! 188: <li>Increased compatibility in the pccons driver with BSDi features.
! 189: <li>Imported FreeBSD's calendar.
! 190: <li>GNU gdb works on the mips-based platforms.
! 191: <li>Add FreeBSD md5 diffs to mtree(8). This can be used to implement a
! 192: tripwire-like system.
! 193: <li>Some YP and bootparamd security changes.
! 194: <li>Hundreds of little fixes all over the place.
! 195: <li>Multiple updates for GNU software
! 196: <li>Add disklabels to the floppy device drivers.
! 197: <li>At boottime, have (*mountroot)() look at the root device's disklabel
! 198: to determine which filesystem type is to be mounted.
! 199: <li>If disklabel reading code discovers an ISOFS filesystem underlying,
! 200: spoof a nice disklabel (enough to fool mountroot).
! 201: <li>tcpdump 3.3
! 202: <li>Fix information gathering attack in ping(8).
! 203: <li>Add NetBSD's "route show" implementation, and at the samet time fix
! 204: the new buffer overflows that this provided.
! 205: <li>Fix a few setgroups() related security holes.
! 206: <li>sendmail 8.8.4
! 207: <li>texinfo 3.9
! 208: <li>f77 0.5.19
! 209: <li>Repair some more KerberosIV buffer overflows. Hard to believe this is
! 210: supposed to be security software.
! 211: <li>Add XCASE/IUCLC/OLCUC/OCRNL/ONOCR/ONLRET tty subsystem flags for
! 212: backwards compatibility.
! 213: <li>Permit NFS attribute cache to be configured on a per-mount basis.
! 214:
! 215: <li>Properly split fsck, mount, and newfs into multiple pieces. Use
! 216: disklabel information if it is available.
! 217: <li>Add disklabels to the vnd device driver.
! 218: <li>Change the games to be run setgid games, not setuid games. This closes
! 219: a whole slew of fascinating security holes.
! 220: <li>Import of the powerpc port.
! 221: <li>Properly use _POSIX_SAVED_IDS throughout the source tree.
! 222: <li>Permit building of kernels without a.out support.
! 223: <li>ppp 2.3b3
! 224: <li>libcrypt goes away. We do not need this stub library anymore. Do not link
! 225: against it on OpenBSD, all the pieces you need are in libc.
! 226: </ul>
! 227: <br>
! 228:
! 229: This list only mentions platform-independent changes. For a list of changes
! 230: made in a particular platform, please check the page for that platform.<br><br>
