<h3>Changes made between OpenBSD 5.1 and 5.2</h3>
<p>

<ul>
<!-- 2012/08/01 -->
<li>Accommodate newer i386/amd64 CPUs with physical address size greater than 36 bit. Fixes major performance hit seen on newer servers where an incorrectly programmed memory region length affects PCI device mappings.
<!-- 2012/07/26 -->
<li>Make <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a> interface_status() assume that a link is up when IFM_AVALID is not set. Allows drivers to get dhcp leases even when they cannot tell what the link state is.
<!-- 2012/07/19 -->
<li>Fix for VU#624931 CVE-2012-2978: <a href="https://man.openbsd.org/nsd.8">nsd(8)</a> denial of service vulnerability from non-standard DNS packet from any host on the internet.
<!-- 2012/07/18 -->
<li>Make the <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a> scheduler less verbose by default.
<li>Further simplify <a href="https://man.openbsd.org/cwm.1">cwm(1)</a> Xinerama init, and re-init on XRR events.
<li>On gio, correctly recognise boards with a 8-bit only ID register, which are not frame buffers.
<li>The 8254 timer does not interrupt on Indy; no longer try it. R4000 and R4400 based Indy may experience the lost clock interrupt processor errata again, until better fix is found.
<li>Drop .sp and .br right after .SH and .SS.; and drop empty .IP so they do not cause additional vertical spacing with <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a>.
<li>Let a trailing .Ns macro take effect, even on an input line containing a partial implicit macro. Fixes some <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> horizontal spacing.
<li>Print messages about <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> ieee80211 nodes purged from the node cache if hostap/ibss modes are compiled in and the interface is in debug mode.
<li>Fix handling of <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> paragraph macros inside lists: when they are trailing the last item, move them outside the list; when they are trailing any other none-compact item, drop them.
<li><a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> will now never use "\*(Ba" and just use "|". Stops breaking of enclosing font changes.
<!-- 2012/07/17 -->
<li>Put p_prof_ticks and p_prof_addr back in a "copy-on-fork" area, to correct process accounting.
<li>Add recognition of the Huawei Mobile E303 to <a href="https://man.openbsd.org/umsm.4">umsm(4)</a>.
<li>Use <a href="https://man.openbsd.org/ipsec.4">ipsec(4)</a> flowinfo on pipex to select the <a href="https://man.openbsd.org/ipsec.4">ipsec(4)</a> tunnel for sending L2TP packets.
<!-- 2012/07/16 -->
<li>In flush-left mode <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a>, when an output line is broken at the position of a literal tab, the tab now indents the following line.
<li>Added IP_IPSECFLOWINFO option to <a href="https://man.openbsd.org/sendmsg.2">sendmsg(2)</a> and <a href="https://man.openbsd.org/recvmsg.2">recvmsg(2)</a>, so <a href="https://man.openbsd.org/npppd.4">npppd(4)</a> can use this to select the <a href="https://man.openbsd.org/ipsec.4">ipsec(4)</a> tunnel for L2TP packets. Fixes Windows (always binding to 1701) and Android clients (negotiating wildcard flows).
<li>Fixed two possible node leaks in ieee80211_input().
<li>Make sure we have a swap partition before trying to read or write hibernate info to it.
<li><a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> -Tman .sp fixes: keep height argument on the same line (it got printed to the output); for .El .sp, avoid the .sp -1v .PP .sp output sequence.
<li><a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> -mdoc parser improvements related to vertical spacing: remove .br before paragraph type blocks; treat .Lp as a paragraph like .Pp (so remove .Pp, .Lp, .br before it); do not treat .sp as a paragraph (don't remove anything before it); after .Sh, .Ss, .Pp, and .Lp, remove .Pp, .Lp, .sp, .br, and blank lines; after .sp and .br, remove .br.
<!-- 2012/07/15 -->
<li>Unify <a href="https://man.openbsd.org/cwm.1">cwm(1)</a> max routines, to match client placement and some menu ones when calculating screen dimensions.
<li>Don't panic in hibernate resume if no swap partition exists on the root disk.
<li>Add <a href="https://man.openbsd.org/cu.1">cu(1)</a> command ~D to drop the DTR line for a second (similar to using ~# for a BREAK). This makes some microcontroller boards reset.
<!-- 2012/07/14 -->
<li>Fixed <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> vertical spacing for blank lines after .PP, and for .sp after .PP; adjust -Tman SYNOPSIS .Nm indentation using .HP; do not pass font escapes and such through print_word(), to correctly count characters.
<li>In <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> -Tman .Bl -compact, skip blank line only before first item of first list in a section, not before every item of the first list.
<li>Label node allocation failures as such in <a href="https://man.openbsd.org/netstat.1">netstat(1)</a> -W output.
<li>Changed <a href="https://man.openbsd.org/ipsec.conf.5">ipsec.conf(5)</a> configuration format fed to the isakmpd FIFO to be able to specify extended options (eg SA Lifetime).
<li>Added <a href="https://man.openbsd.org/sysctl.conf.5">sysctl.conf(5)</a> file for beagleboard architecture (required by the cross compiler).
<li>Refined <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> knexthop calculations. Fixes massive memory consumption crashes when used with <a href="https://man.openbsd.org/ospfd.8">ospfd(8)</a>.
<li>Support additional MODP DH groups in the <a href="https://man.openbsd.org/isakmpd.policy.5">isakmpd.policy(5)</a> Phase 1 and Phase 2, to match <a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>.
<li>Stopped <a href="https://man.openbsd.org/npppd.4">npppd(4)</a> using wrong Attribute Value Pairs as a "calling number".
<li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> now recognises additional Internet Key Exchange DH groups.
<li><a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> changes: in -man -Tascii, support .sp with negative argument; in -mdoc -Tman, improve the framework to control vertical spacing. Use both to support .Bl -compact.
<li>Add a notify queue to <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> and a way to turn them on and off, to prevent notify while running some commands.
<!-- 2012/07/13 -->
<li>Import swrastg, the Gallium3D software rasterizer. Uses the softpipe driver by default, can also use the llvmpipe driver that use LLVM for code generation if available. Not yet linked to the build.
<li>Avoid using the same <a href="https://man.openbsd.org/wscons.4">wscons(4)</a> wchan name twice.
<li>Disable <a href="https://man.openbsd.org/acpivideo.4">acpivideo(4)</a> on ASUS laptops, as some models panic whenever an event is received.
<li>Fix wireless scanning on slow systems with high RX rate and interface in debug mode. Allows association points to recover from <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> "ral0 debug down up" in noisy RF environments. Also fixed some association failures.
<li>Allow <a href="https://man.openbsd.org/route.8">route(8)</a> destination/prefixlen syntax for ipv6 routes.
<li>After connect() returns EINPROGRESS the connection can still fail, <a href="https://man.openbsd.org/relayd.8">relayd(8)</a> will now check with getsockopt if the socket is still open.
<li>Use S_ISFIFO and S_ISSOCK instead of lseek() to determine whether a fd is a socket, pipe or named pipe.
<li>Fix .Nm validation crash in <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a>.
<li>Be more careful when accessing a possibly cached route, since it may already be gone. Fixes panic seen when unplugging a USB interface in use.
<li>Added -B option to <a href="https://man.openbsd.org/ktrace.1">ktrace(1)</a> to reduce <a href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> chatter.
<li>Better handling of long comments in <a href="https://man.openbsd.org/ssh_config.5">ssh_config(5)</a>.
<li>Fix installer script issue where ksh would not properly separate arguments correctly in "$@" if IFS is an empty string.
<li>Enabled hibernate on i386. Currently only working on <a href="https://man.openbsd.org/pciide.4">pciide(4)</a> and <a href="https://man.openbsd.org/wd.4">wd(4)</a> disks.
<li>Improved i386 gdb to display stack traces of kernel core dumps correctly.
<li>Fix crash in <a href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> on .Fn with one argument and .Bl without a width. Now can build all 3776 base manuals.

<li>Added support for NetMos NM9820 cardbus serial cards.
<li>Added JMC251/JMC261 chips which include card readers to the list of supported <a href="https://man.openbsd.org/jme.4">jme(4)</a> devices.
<!-- 2012/07/12 -->
<li>Make <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a> not respect RFC5322 and refuse strange characters in the local part of an email address.
<li>Implemented <a href="https://man.openbsd.org/res_mkquery.3">res_mkquery(3)</a> in the libc async resolver.
<li>When <a href="https://man.openbsd.org/cp.1">cp(1)</a> copies a file using sparse mode, truncate the file based on current seek offset instead of the reported original length.
<li>USB HID parser now supports multiple report IDs. Added <a href="https://man.openbsd.org/hid_get_report_id.3">hid_get_report_id(3)</a> to get an id of a descriptor.
<li>New event-driven tftp-proxy(8) replaces the old one run out of <a href="https://man.openbsd.org/inetd.8">inetd(8)</a>.
<li>Disabled SSLv2 in the OpenSSL code base.
<li>Better <a href="https://man.openbsd.org/fdisk.8">fdisk(8)</a> bounds checks and less unuseful help texts.
<li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, limit the <a href="https://man.openbsd.org/setsockopt.2">setsockopt(2)</a> while loops to prevent them from running away if the call fails when a peer bounces at the wrong time.
<li>Fix <a href="https://man.openbsd.org/libtool.1">libtool(1)</a> handling of ldconfig library directory searches.
<li>Make <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> command exec functions return an enum rather than -1/0/1 values and add new value to mean "leave client running but don't attach". Fixes problems with using some commands in a command sequence.
<!-- 2012/07/11 -->

<li>Start using our options parser for main <a href="https://man.openbsd.org/libtool.1">libtool(1)</a> options; put link related stuff into their own module; shortdie for cases where it is known <a href="https://man.openbsd.org/libtool.1">libtool(1)</a> is not at fault.
<!-- 2012/07/08 -->

<li>The <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> display-message command is extended by a <b>-F</b> option which can be used to specify a format string to control output formatting.
<li>New functions are added to the thread library: pthread_mutex_timedlock(3), pthread_condattr_getclock(3) and pthread_condattr_setclock(3); also, PTHREAD_MUTEX_NORMAL mutexes learn about self-deadlocks.
<li><a href="https://man.openbsd.org/snmpd.8">snmpd(8)</a> gains the MIB module for gathering information from OpenBSD's packet filter.
<!-- 2012/02/22 -->
<li>In <a href="https://man.openbsd.org/chroot.2">chroot(2)</a> mode nginx(8) first <a href="https://man.openbsd.org/chdir.2">chdir(2)</a>s to the PREFIX directory before it starts to create it's temporary directories.
<!-- 2012/02/21 -->
<li>The pthread_suspend_np(3) and pthread_resume_np(3) function are no longer functional and become ENOTSUP stubs.
<!-- 2012/02/20 -->
<li>A lot of work is being done for making process tracing work with rthreads.
<li>In Xenocara, update xf86-video-geode 2.11.13 and xf86-video-dummy to 0.3.5.
<li><a href="https://man.openbsd.org/kdump.1">kdump(1)</a> fixes an integer flip which could have happened for a kernel trace record with ktr_len of SIZE_MAX and would have caused a zero byte data allocation. It also learns more system calls and refactors output routines as well as the output produced by the latter.
<li>A lot of work is being done on regression tests for threads.
<!-- 2012/02/19 -->
<li>Bugfix in <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> to correctly check BGP prefix lengths in withdrawn routes.
<li>Fix return value documentation errors in <a href="https://man.openbsd.org/usbhid.3">usbhid(3)</a>.
<li>Allow for more vars in <a href="https://man.openbsd.org/ksh.1">ksh(1)</a> hash table, improve hash function, increase hash table size sooner.
<!-- 2012/02/18 -->
<li>Initialize the scope, policy, and inherit members in pthread_attr_init() so that their pthread_attr_get* don't return bogus values.
<li>Update nginx in base to 1.0.12 and sync its <a href="https://man.openbsd.org/pcre.3">pcre(3)</a> with the version in ports.
<li>Update to <a href="https://man.openbsd.org/mkfontdir.1">mkfontdir(1)</a> 1.0.7, <a href="https://man.openbsd.org/mkfontscale.1">mkfontscale(1)</a> 1.1.0, <a href="https://man.openbsd.org/oclock.1">oclock(1)</a> 1.0.3, <a href="https://man.openbsd.org/xclipboard.1">xclipboard(1)</a> 1.1.2, <a href="https://man.openbsd.org/xclock.1">xclock(1)</a> 1.0.6, <a href="https://man.openbsd.org/xcmsdb.1">xcmsdb(1)</a> 1.0.4, <a href="https://man.openbsd.org/xcompmgr.1">xcompmgr(1)</a> 1.1.6, <a href="https://man.openbsd.org/xfd.1">xfd(1)</a> to 1.1.1 and util-macros to 1.16.1.
<!-- 2012/02/17 -->
<li>Add DIAGNOSTICS to <a href="https://man.openbsd.org/bsd.port.mk.5">bsd.port.mk(5)</a>, for easy grepping through logs, and no longer label "warning messages" as "errors".
<!-- 2012/02/16 -->
<li><a href="https://man.openbsd.org/pkill.1">pkill(1)</a> will now exit usage() with STATUS_BADUSAGE rather than STATUS_ERROR, in agreement with the man page.
<li>Set __isthreaded in <a href="https://man.openbsd.org/pthread_create.3">pthread_create(3)</a>, i.e. even if a forked child creates a new thread. Fixes an rthread bug to properly represents whether a process is multi-threaded or not.
<li>Do an explicit "sync" instruction before returning from cache routines on mips64 (nop on R5k/RM52xx, but required on RM7k).
<li>Add <a href="https://man.openbsd.org/kevent.2">kevent(2)</a> support for msdosfs to make applications monitoring fs mounts happy.
<!-- 2012/02/15 -->
<li>Enable rthreads by default (threads now in kernel not userspace), and add additional pthreads regression tests.
<li>Hold struct filedesc's fd_lock in more places. Fixes hangs in rthreaded processes calling <a href="https://man.openbsd.org/fork.2">fork(2)</a>.
<li>No longer attempt to enable MSI on 82571/82572 <a href="https://man.openbsd.org/em.4">em(4)</a> Gigabit ethernet controllers (to workaround "Byte Enables 2 and 3 Are Not Set" hardware bug).
<!-- 2012/02/13 -->
<li><a href="https://man.openbsd.org/pkg_create.1">pkg_create(1)</a> now warns when @option no-default-conflict has been set without explicit @conflict.
