72: <p>
73: This is a partial list of new features and systems included in OpenBSD 7.2.
74: For a comprehensive list, see the <a href="plus72.html">changelog</a> leading
75: to 7.2.
76:
77: <ul>
78:
79: <li>New/extended platforms:
80: <ul>
1.4 jsg 81: <li>Added support for Ampere Altra
82: <li>Added support for Apple M2
1.35 benno 83: <li>Added support for Lenovo ThinkPad x13s and other machines using
1.34 benno 84: the Qualcomm Snapdragon 8cx Gen 3 (SC8280XP) SoC.
1.1 deraadt 85: </ul>
86:
87: <li>Various kernel improvements:
88: <ul>
1.12 benno 89: <li>Allowed bsd.rd and bsd/bsd.mp to boot on Oracle Cloud amd64 instances.
90: <li>Added support for switching from glass console to serial console
91: on arm64 systems that default to glass console.
1.16 jsg 92: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a> automatically allows
1.44 ! benno 93: IGMP and ICMP6 MLD packets with router alert option.
! 94: Special allow-opts rules are no longer needed for multicast
! 95: discovery.
1.19 benno 96: <li>Fixed a <a href="https://man.openbsd.org/pf.4">pf(4)</a> NULL
97: dereference panic triggered by <a
98: href="https://man.openbsd.org/relayd.8">relayd(8)</a>.
1.16 jsg 99: <li>Implement "show all routes" to print routing tables in
100: <a href="https://man.openbsd.org/ddb.4">ddb(4)</a>.
1.29 benno 101: <li>Added a method (ESC D) to enter <a
102: href="https://man.openbsd.org/ddb.4">ddb(4)</a> on serial drivers that
103: do not have a true BREAK mechanism.
104: <li>Added "show all routes" and the ability to show individual routes
105: (e.g. "show route 0xfffffd807e9b0000") to <a
106: href="https://man.openbsd.org/ddb.4">ddb(4)</a>.
107: <li>Added a "show swap" command to <a
108: href="https://man.openbsd.org/ddb.4">ddb(4)</a> to help debugging.
1.16 jsg 109: <li>Count dropped network packets due to low memory in
110: <a href="https://man.openbsd.org/netstat.1">netstat(1)</a>.
1.12 benno 111: <li>Simplified machine command handling in <a
112: href="https://man.openbsd.org/ddb.4">ddb(4)</a>.
113: <li>Changed to a simpler formula to calculate a default kern.maxthread
114: value: 2*NPROCESS.
115: <li>Enabled <a href="https://man.openbsd.org/kstat.4">kstat(4)</a>, a
116: device that exports kernel statistics that can be read by <a
1.23 jsg 117: href="https://man.openbsd.org/kstat.1">kstat(1)</a>.
1.13 benno 118: <li>Added cpu frequency sensors for each core on CPUs that have MPERF/APERF support.
1.14 benno 119: <li>Merged the UVM swap-backed and object-backed inactive page lists.
120: <li>Fixed <a href="https://man.openbsd.org/rwlock.9">rwlock(9)</a>
121: implementation to be fair to writers. Previously, readers could grab
122: the lock even if writers were waiting first.
123: <li>Made the CPU frequency scaling duration relative to the load
124: when in automatic mode on battery.
125: <li>Fixed luna88k MULTIPROCESSOR kernels booting with CPU modules
126: installed in arbitrary slots.
1.19 benno 127: <li>Added a missing <a
128: href="https://man.openbsd.org/kqueue.2">kqueue(2)</a> wakeup, found by
129: a Go testcase hang.
130: <li>Bumped the maximum number of supported CPUs to 256 on arm64.
1.44 ! benno 131: <!-- XXX should the following be here (swapper, pmem...) or maybe one entry describing them together? -->
1.29 benno 132: <li>Ensure uvm_swap_io() can succeed, even in out of memory
133: situations, by reserving a second segment for the page daemon.
134: <li>Ensured progress in the swapper by pre-allocating pages in a DMA-reachable region.
135: <li>Made the page daemon consider pmemrange regions when trying to
136: free pages from the inactive list. Previously the page daemon could
137: use a lot of CPU without freeing a page because the global limits were
138: satisfied.
139: <li>Ensured that uvm_swap_get() will always sleep rather than
140: returning an error. Previously an error could be returned to the fault
141: handler which would result in processes dying when a system was under
142: a lot of memory pressure.
1.44 ! benno 143: <!-- ... up to here -->
1.29 benno 144: <li>Added support for using non-standard UARTs (such as the Synopsys
145: DesignWare UART) as an early console.
146: <li>Remove NexGen CPU identification code as the kernel cannot run on these CPUs anyway.
147: <li>Remove Rise CPU identification code.
1.32 benno 148: <li>Dropped detection code for 386sx/386dx CPUs. OpenBSD/i386 hasn't
149: actually supported running on either for some time.
150: <li>Dropped detection code for Cyrix CPUs older than the Cyrix M2.
1.29 benno 151: <li>Implemented the fundamentals for suspend/resume on arm64.
1.32 benno 152: <li>Simplified TSC synchronization testing on amd64.
153: <li>Corrected sparc64 ofwboot to default to the <a
154: href="https://man.openbsd.org/softraid.4">softraid(4)</a> volume on the
155: boot device to make root on softraid work out of the box on sparc64
156: and be more consistent with softraid boot on other architectures.
157: <li>Added support for booting from RAID 1C <a
158: href="https://man.openbsd.org/softraid.4">softraid(4)</a> volumes on
159: amd64, sparc64 and arm64.
160: <li>Removed the obsolete kern.nselcoll <a
161: href="https://man.openbsd.org/sysctl.2">sysctl(2)</a>.
162: <li>Changed mips64, octeon, and loongson to trigger deferred clock
163: interrupts from <a href="https://man.openbsd.org/splx.9">splx(9)</a>.
164: This isolates the clock interrupt schedule from the MD clock interrupt
165: code.
166: <li>Fixed a potential kernel panic when an msdos partition is out
167: of space by fixing instances where msdosfs passed a NULL proc pointer
168: to detrunc().
169: <li>Add a delay_init() function that helps on i386 and amd64
170: architectures in setting up delay_func for different timers and
171: switching between them depending on their quality properties. This
172: improves how timers backing <a
173: href="https://man.openbsd.org/delay.9">delay(9)</a> are managed.
1.1 deraadt 174: </ul>
175:
176: <li>SMP Improvements
177: <ul>
1.39 jsg 178: <li>Make route timer MP safe and use rttimer pool.
1.9 bluhm 179: <li>Use kernel lock to protect parts of ARP, ND6 and PPPoE that
180: are not MP safe.
181: Lookup of existing ARP entry is MP safe and can run in parallel.
182: <li>Start up to 4 softnet tasks to run IP input and forwarding
183: in parallel on multiple cores.
184: <li>Run IPv4 packet reassembly in parallel.

187: <li>Introduce mutex and reference counter for internet protocol
188: control block.
189: <li>Protect UDP, raw IP, and divert packet input routines
190: with a per socket mutex.
1.16 jsg 191: <li>Protect <a href="https://man.openbsd.org/recv.2">recv(2)</a> system call
192: for UDP and raw IP packets with a per socket mutex and shared netlock.
1.9 bluhm 193: Allows to receive packets while forwarding in parallel.
194: <li>Protect multicast deliver loop for UDP and raw IP sockets with rwlock.
1.13 benno 195: <li>Only grab netlock in IGMP and MLD timer when necessary.
1.9 bluhm 196: <li>TCP slow timer runs without netlock.
197: <li>Rework rwlock so that a writer will get the lock eventually.
198: Readers cannot share the lock forever.
199: This prevents starvation of the writer.
200: <li>Run interface media ioctl with shared netlock so packets
1.16 jsg 201: can be processed while running
202: <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>.
203: <li><a href="https://man.openbsd.org/btrace.8">btrace(8)</a> can be used
204: to debug reference counting.
1.9 bluhm 205: <li>Use MP safe refcount for interface addresses.
1.29 benno 206: <li>Unlocked <a href="https://man.openbsd.org/kbind.2">kbind(2)</a>.
207: <li>Unlocked the <a href="https://man.openbsd.org/pledge.2">pledge(2)</a> system call.
208: <li>Made <a href="https://man.openbsd.org/unix.4">unix(4)</a> domain
209: sockets locking per-socket rather than coarse locking of the entire
210: domain sockets layer.

1.13 benno 220: href="https://man.openbsd.org/bus_dma.9">bus_dma(9)</a> APIs to make
221: sure DMA addresses are translated properly on architectures with an
222: IOMMU. This fixed <a
223: href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> and <a
224: href="https://man.openbsd.org/radeondrm.4">radeondrm(4)</a> on
1.42 jsg 225: powerpc64, sparc64, and arm64 machines with SMMU.
1.29 benno 226: <li>Implemented support for framebuffers that don't start on a page
1.41 jsg 227: boundary (like those on the 2021 14" and 16" MacBook Pro).
1.29 benno 228: <li>Added handling for framebuffers where the first pixel isn't

310: href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a> to prevent
311: O(n^2) behavior when packages contain several hundred copies of the
312: same file.
1.29 benno 313: <li>Added a "processing" message for when <a
314: href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a> is
315: transferring data to inform the user that pkg_add is still working.
316:
1.37 benno 317: <!-- fdisk -->
1.13 benno 318: <li>Added missing uuid_dec_le() to init_fp() so <a
319: href="https://man.openbsd.org/fdisk.8">fdisk(8)</a> -A works on
320: big-endian architectures.
1.14 benno 321: <li>Aligned <a href="https://man.openbsd.org/fdisk.8">fdisk(8)</a>
322: logic with that used in the kernel to allow the protective EFI GPT

338: a warning when an MBR partition starts or extends past the end of the
339: device.
340: <li>Made <a href="https://man.openbsd.org/fdisk.8">fdisk(8)</a> print
341: a warning when a GPT partition start or end is outside the usable LBA
342: area of the device.
1.14 benno 343:
1.37 benno 344: <!-- btrace -->
345: <li>Installed useful <a

770: <li>Abort a currently running RRDP request process when the per-repository
771: timeout is reached.
772: <li>Permit multiple AccessDescription entries in SIA X.509 extensions. While

1223: <section id=sourcecode>
1224: <h3>Notes about the source code</h3>
1225: <p>
1226: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1227: This file contains everything you need except for the kernel sources,
1228: which are in a separate archive.
1229: To extract:
1230: <blockquote><pre>
1231: # <kbd>mkdir -p /usr/src</kbd>
1232: # <kbd>cd /usr/src</kbd>
1233: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1234: </pre></blockquote>
1235: <p>
1236: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1237: This file contains all the kernel sources you need to rebuild kernels.
1238: To extract:
1239: <blockquote><pre>
1240: # <kbd>mkdir -p /usr/src/sys</kbd>
1241: # <kbd>cd /usr/src</kbd>
1242: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1243: </pre></blockquote>
1244: <p>
1245: Both of these trees are a regular CVS checkout. Using these trees it
1246: is possible to get a head-start on using the anoncvs servers as
1247: described <a href="anoncvs.html">here</a>.
1248: Using these files
1249: results in a much faster initial CVS update than you could expect from
1250: a fresh checkout of the full OpenBSD source tree.

1256: <h3>Ports Tree</h3>
1257: <p>
1258: A ports tree archive is also provided. To extract:
1259: <blockquote><pre>
1260: # <kbd>cd /usr</kbd>
1261: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1262: </pre></blockquote>
1263: <p>
1264: Go read the <a href="faq/ports/index.html">ports</a> page
1265: if you know nothing about ports
1266: at this point. This text is not a manual of how to use ports.
1267: Rather, it is a set of notes meant to kickstart the user on the
1268: OpenBSD ports system.
1269: <p>
1270: The <i>ports/</i> directory represents a CVS checkout of our ports.
1271: As with our complete source tree, our ports tree is available via
1272: <a href="anoncvs.html">AnonCVS</a>.
1273: So, in order to keep up to date with the -stable branch, you must make
1274: the <i>ports/</i> tree available on a read-write medium and update the tree
1275: with a command like:
1276: <blockquote><pre>
1277: # <kbd>cd /usr/ports</kbd>
1278: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_2</kbd>
1279: </pre></blockquote>
1280: <p>
1281: [Of course, you must replace the server name here with a nearby anoncvs
1282: server.]
1283: <p>
1284: Note that most ports are available as packages on our mirrors. Updated
1285: ports for the 7.2 release will be made available if problems arise.
1286: <p>
1287: If you're interested in seeing a port added, would like to help out, or just
1288: would like to know more, the mailing list
1289: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
