<h3>Changes made between OpenBSD 3.4 and 3.5</h3>
<p>

<ul>
<!-- ^ 20040330 -->
<li>Don't use <a href="https://man.openbsd.org/select.2">FD_ZERO(2)</a> in <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a>'s privsep monitor.
<li>When binding UDP server sockets in <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a>, check the sockaddr buffer is large enough before copying.
<!-- ^ 20030429 -->
<li>Add some extra sanity checks for incoming <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> packets.
<li>Fix a kernel memory leak when deleting interface addresses (SIOCDIFADDR).
<!-- ^ 20040328 -->
<li>Add a missing <a href="https://man.openbsd.org/spl.9">spl(9)</a> around if_down() in <a href="https://man.openbsd.org/vlan.4">vlan(4)</a>.
<!-- ^ 20040327 -->
<li>In <a href="https://man.openbsd.org/pf.4">pf(4)</a>, properly <a href="https://man.openbsd.org/m_copyback.9">m_copyback(9)</a> the modified TCP sequence number after demodulation.<br>
    <a href="stable.html">[Applied to stable]</a>
<li>Fix a use-after-free in <a href="https://man.openbsd.org/carp.4">carp(4)</a>.
<li>Raise <a href="https://man.openbsd.org/carp.4">carp(4)</a> advskew to 240 while waiting for the <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> bulk update. This makes sure that other hosts can preempt a host that's booting up but hasn't got its network bearings yet.
<!-- ^ 20040326 -->
<li>Fix a check-for-null-then-deref-anyway bug in icmp6.
<li>Fix a cut-and-pasto in <a href="https://man.openbsd.org/pf.4">pf(4)</a>'s stateful ICMP code.
<li>Unbreak the ICMP checksum when <a href="https://man.openbsd.org/pf.4">pf(4)</a> sequence number modulation is used.<br>
    <a href="stable.html">[Applied to stable]</a>
<!-- ^ 20040325 -->
<li>Disable carp error logging (<a href="https://man.openbsd.org/sysctl.3">sysctl(3)</a> net.inet.carp.log) by default.
<!-- ^ 20040324 -->
<li>Remove an unnecessary null termination in the <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a> privsep monitor.
<li>Teach <a href="https://man.openbsd.org/file.1">file(1)</a> about OpenBSD-amd64 binaries and coredumps.
<li>Add a small delay before the bulk update to stop <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> looping unnecessarily.
<!-- ^ 20040323 -->
<li>Fix <a href="https://man.openbsd.org/ssl.3">ssl(3)</a> rmd160 breakage on sparc64.
<li>Teach <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> how to display the new <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> bulk updates.
<li>Make <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> stop <a href="https://man.openbsd.org/carp.4">carp(4)</a> preempting to become master until the bulk state table sync has completed.
<li>Support best-efforts bulk transfers of states when a <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> syncif is first configured. This allows pfsync+carp clusters to come up gracefully without killing active connections.
<li>Have <a href="https://man.openbsd.org/rc.8">rc(8)</a> stop <a href="https://man.openbsd.org/carp.4">carp(4)</a> interfaces on system shutdown.
<li>Add pass rules for the pfsync and carp protocols to the default <a href="https://man.openbsd.org/pf.4">pf(4)</a> rulebase installed by /etc/<a href="https://man.openbsd.org/rc.8">rc(8)</a>.
<li>Make sure <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> interfaces are initialised before <a href="https://man.openbsd.org/carp.4">carp(4)</a> interfaces in /etc/<a href="https://man.openbsd.org/netstart.8">netstart(8)</a>.
<!-- ^ 20040322 -->
<!-- ^ 20040321 -->
<li>Unbreak routing change handling in <a href="https://man.openbsd.org/carp.4">carp(4)</a>.
<li>Bump OpenSSH to version 3.8.1.
<li>Make <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>'s '-s osfp' option work by spelling it less like OSPF.
<li>Update <a href="https://man.openbsd.org/pf.os.5">pf.os(5)</a> to include OpenBSD 3.5, since that's where it's now at.
<li>Have <a href="https://man.openbsd.org/tn3270.1">tn3270(1)</a> check errno instead of setting it.
<li>Fix yet another stray semicolon, this time in <a href="https://man.openbsd.org/aac.4">aac(4)</a>.
<li>Implement firmware downloading for <a href="https://man.openbsd.org/mpt.4">mpt(4)</a>.
<!-- ^ 20040320 -->
<li>Make <a href="https://man.openbsd.org/bge.4">bge(4)</a> work on 64-bit machines even if they're not alphas.
<li>Have privsep <a href="https://man.openbsd.org/named.8">named(8)</a> pass SIGINT to the child process.
<li>Upgrade Puffy to 3.5 and lock XF4 for release.
<li>Add final pieces of privilege separation for <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a> and switch it on.
<li>Add <a href="https://man.openbsd.org/i386/pxeboot.8">pxeboot(8)</a> for i386 and amd64, derived from NetBSD.
<li>Fix another stray semicolon, in <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>'s ASN.1 printer this time.
<li>More <a href="https://man.openbsd.org/mpt.4">mpt(4)</a> fixes, more to come.
<!-- ^ 20040319 -->
<li>When initialising the new state in <a href="https://man.openbsd.org/pf.4">pf(4)</a> DIOCADDSTATE, point to the default rule instead of NULL.
<li>Merge parts of XFree86 4.4.0 Release not affected by the new license.
<li>Allow a <a href="https://man.openbsd.org/carp.4">carp(4)</a> device's state to be set explicitly with <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>.
<li>Set permissions on the right files for the @owner, @group and @mode directives in <a href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a> when -B is in effect.
<li>For <a href="https://man.openbsd.org/wi.4">wi(4)</a> devices with Prism firmware version 1.6.3 or later, support an enhanced security mode for a hostap where the SSID can be hidden from snoopers.
<li>Speed up <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> session reestablishment.

  <!-- Erratum 015 (isakmpd) applied to stable here, -current is 20040310  -->
<li>Fix <a href="https://man.openbsd.org/spamd.8">spamd(8)</a>'s logging when the blacklist limit is hit.
<li>Allow users with write access to <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>'s control socket to send queries.
<li>Fix an out-of-bounds read in <a href="https://man.openbsd.org/ssl.3">ssl(3)</a> (CAN-2004-0112). This code isn't used in OpenBSD.
<li>Always read at least DEV_BSIZE (512) bytes of the disklabel, some disks have smaller block sizes.
<li><strong>RELIABILITY FIX: A missing check for a NULL-pointer dereference has been found in ssl(3).</strong> A remote attacker can use the bug to cause an OpenSSL application to crash; this may lead to a denial of service.<br>
    <a href="errata34.html#openssl">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<li>Fix a minor memory leak in <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a>.
<li>Lots of pre-release documentation fixes and additions.
<li>If running at <a href="https://man.openbsd.org/securelevel.7">securelevel(7)</a> 2, use the -x option to increase the chances of ntpd using slew mode, since stepping backwards is disabled at this level.
<li>Some <a href="https://man.openbsd.org/mpt.4">mpt(4)</a> stability fixes.
<!-- ^ 20040317 -->
<li>Don't signal <a href="https://man.openbsd.org/mountd.8">mountd(8)</a> from <a href="https://man.openbsd.org/mount.8">mount(8)</a> when all that's required is a listing of mounts (PR#3695).
<li>Create <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>'s control socket later in the startup.
<li>Remember to unlock USB <a href="https://man.openbsd.org/wi.4">wi(4)</a> devices on errors.
<li>Since we've allocated a cache for <a href="https://man.openbsd.org/pax.1">pax(1)</a>, let's go right ahead and use it.
<li>Remove 'extern int errno' in favour of #include &lt;errno.h&gt; in a number of programs.
<li>Have <a href="https://man.openbsd.org/diff.1">diff(1)</a> in directory mode skip over anything that's not a regular file or directory, for POSIX reasons.
<!-- ^ 20040316 -->
<li>Yet another stray semicolon removed, <a href="https://man.openbsd.org/pax.1">pax(1)</a> is the lucky program.
<li>Prevent blacklist connections we're tarpitting from maxing out <a href="https://man.openbsd.org/spamd.8">spamd(8)</a>'s available connections. Controllable with the new -B option.
<li>Have <a href="https://man.openbsd.org/wi.4">wi(4)</a> hostap send an error response if a station sends a bogus challenge instead of just ignoring it.
<li>Make software WEP work on <a href="https://man.openbsd.org/wi.4">wi(4)</a> devices. Only in BSS (station) and hostap modes for now.
<li>Fix another bug caused by a stray semicolon, this time in <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>.
<li><a href="https://man.openbsd.org/daemon.3">daemon(3)</a>ise ifstated(8) earlier.
<li>Some logic fixes and additional error checks in USB <a href="https://man.openbsd.org/wi.4">wi(4)</a>.
<li>Have <a href="https://man.openbsd.org/sensorsd.8">sensorsd(8)</a> deal gracefully with attempts to initialise unsupported sensor types.
<li>Fix memory leak caused by a stray semicolon in arla.
<li><a href="https://man.openbsd.org/panic.9">panic(9)</a> if an attempt is made to use the kernel arc4random generator too early.
<li>Fix occasional <a href="https://man.openbsd.org/locate.updatedb.8">locate.updatedb(8)</a> failures due to a bug in <a href="https://man.openbsd.org/sort.1">sort(1)</a>.

<li>Clear struct sockaddr_un before use in <a href="https://man.openbsd.org/syslogc.8">syslogc(8)</a>.
<!-- ^ 20030315 -->
<li>In <a href="https://man.openbsd.org/spamd.8">spamd(8)</a>, only shrink the window once we're in the DATA mode. This way, greylisted connections don't get held up by the tiny window but spam bodies are still sent. Very. Slowly.
<li>Restore <a href="https://man.openbsd.org/scsi.4">scsi(4)</a> bus scans to full speed by not checking LUNs that will be skipped anyway.

<li>Check the return code of <a href="https://man.openbsd.org/chdir.2">chdir(2)</a> after the privsep <a href="https://man.openbsd.org/chroot.2">chroot(2)</a> in <a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a>, <a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a> and <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>.
<li>Disable <a href="https://man.openbsd.org/crypto.9">crypto(9)</a> MAC functions for now, no current hardware can use them.
<li>Some <a href="https://man.openbsd.org/oosiop.4">oosiop(4)</a> cleanup based on <a href="https://man.openbsd.org/osiop.4">osiop(4)</a>.
<li>In <a href="https://man.openbsd.org/wskbd.4">wskbd(4)</a>, make the caps lock key do caps lock instead of shift lock (PR#2555).
<!-- ^ 20040314 -->
<li>Make it easier to kill <a href="https://man.openbsd.org/spamd.8">spamd(8)</a> greylisted processes.
<li>Do <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> interface setup last in /etc/<a href="https://man.openbsd.org/netstart.8">netstart(8)</a>, so that hopefully the syncif gets set up beforehand.
<!-- ^ 20040313 -->
<li>Make <a href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a>'s empty-as keyword work.
<li>Extra free-then-NULL paranoia in <a href="https://man.openbsd.org/spamd.8">spamd(8)</a>.
<li>Fix <a href="https://man.openbsd.org/wi.4">wi(4)</a> software WEP on big-endian machines.

<li>Implement privilege separation for <a href="https://man.openbsd.org/named.8">named(8)</a>. And there was much rejoicing.
<li>Plug a rtentry leak when TCP gives up on a cached route (in_pcb.c:in_losing()).
<li>Fix (guess what?) a memory leak in the <a href="https://man.openbsd.org/yacc.1">yacc(1)</a> skeleton code.
<li>Check the payload size more carefully when printing IKE messages in <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>.
<li>Plug a memory leak in the error path of <a href="https://man.openbsd.org/execve.2">execve(2)</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<li>Preliminary port of the NetBSD <a href="https://man.openbsd.org/oosiop.4">oosiop(4)</a> driver, supporting really old NCR SCSI chips on hppa machines.
<!-- ^ 20040312 -->
<li>Unbreak <a href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a>'s handling of packages from stdin.
<li>Fix a bug in <a href="https://man.openbsd.org/spamd.8">spamd(8)</a> that stopped custom 450 messages being displayed.
<li>Some <a href="https://man.openbsd.org/apm.4">apm(4)</a> fixes on i386.
<li>Sync the <a href="https://man.openbsd.org/spamd.8">spamd(8)</a> greylist database after each db operation, to minimise the likelihood of corruption.

<!-- ^ 20040311 -->
  <!-- I know the erratum says March 17, but this is when the -current patch goes in. -->
<li><strong>RELIABILITY FIX: Defects in the payload validation and processing functions of isakmpd(8) have been discovered.</strong> An attacker could send malformed ISAKMP messages and cause isakmpd to crash or to loop endlessly.<br>
    <a href="errata34.html#isakmpd2">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<li>Obey the user's 'boot reboot' command at the <a href="https://man.openbsd.org/ddb.4">ddb(4)</a> prompt, even if the system is starting up.
<li>Some signedness paranoia when handling <a href="https://man.openbsd.org/carp.4">carp(4)</a> sysctls.

<!-- ^ 20040310 -->
<li>Allow the <a href="https://man.openbsd.org/wsdisplay.4">wsdisplay(4)</a> screen blanker to be turned off again (PR#3123).

<li>Increase the <a href="https://man.openbsd.org/ssh.1">ssh(1)</a> X11 cookie lifetime from two to twenty minutes.
<li>Plug some memory leaks in error paths of <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a>.
