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.

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
83: <li>Added support for Qualcomm Snapdragon 8cx Gen 3 (SC8280XP)
1.1 deraadt 84: <li>...
85: </ul>
86:
87: <li>Various kernel improvements:
88: <ul>
1.9 bluhm 89: <li>pf(4) automatically allows IGMP and ICMP6 MLD packets with
90: router alert option.
91: Special allow-opts rules are no longer needed for multicast
92: discovery.
93: <li>Implement "show all routes" to print routing tables in ddb(4).
94: <li>Count dropped network packets due to low memory in netstat(1).
1.1 deraadt 95: <li>...
96: </ul>
97:
98: <li>SMP Improvements
99: <ul>
1.9 bluhm 100: <li>Make route timer MP safe and use pool rttmr.
101: <li>Use kernel lock to protect parts of ARP, ND6 and PPPoE that
102: are not MP safe.
103: Lookup of existing ARP entry is MP safe and can run in parallel.
104: <li>Start up to 4 softnet tasks to run IP input and forwarding
105: in parallel on multiple cores.
106: <li>Run IPv4 packet reassembly in parallel.
107: <li>Run IPv6 hop-by-hop options processing in parallel.
108: <li>Add a mutex to rate limiting functions to make them MP safe.
109: <li>Introduce mutex and reference counter for internet protocol
110: control block.
111: <li>Protect UDP, raw IP, and divert packet input routines
112: with a per socket mutex.
113: <li>Protect recv(2) system call for UDP and raw IP packets with
114: a per socket mutex and shared netlock.
115: Allows to receive packets while forwarding in parallel.
116: <li>Protect multicast deliver loop for UDP and raw IP sockets with rwlock.
117: <li>Only grab netlock in IGMP and MDL6 timer when necessary.
118: <li>TCP slow timer runs without netlock.
119: <li>Rework rwlock so that a writer will get the lock eventually.
120: Readers cannot share the lock forever.
121: This prevents starvation of the writer.
122: <li>Run interface media ioctl with shared netlock so packets
123: can be processed while running ifconfig(8).
124: <li>btrace(8) can be used to debug reference counting.
125: <li>Use MP safe refcount for interface addresses.

! 274: <ul>
! 275: <li>Do not apply timezone offsets when converting X509 times. X509
! 276: times are in UTC and comparing them to times in different timezones
! 277: would cause validity problems.
! 278: <li>Add support for an operator-configurable skiplist facility.
! 279: Operators can specify a list of FQDNs which should not be contacted
! 280: when synchronizing the local cache to the network.
! 281: <li>Emit a warning when a RRDP session serial number decreases.
! 282: <li>DER decoding functions were refactored to leverage ASN.1 templates.
! 283: <li>Add support to validate & inspect .sig files containing RPKI Signed
! 284: Checklists in filemode (-f). (draft-ietf-sidrops-rpki-rsc-08)
! 285: <li>Print various statistics after the completion of the main process.
! 286: <li>Add support to decode & print TAL (RFC 8630) details in filemode (-f).
! 287: <li>Emit objects in Concatenated JSON format when filemode (-f) and the JSON
! 288: output flag (-j) are combined.
! 289: <li>Add suport for validating Autonomous System Provider Authorization
! 290: (ASPA) objects conforming to draft-ietf-sidrops-aspa-profile-10.
! 291: Validated ASPA payloads are visible in JSON and filemode (-f) output.
! 292: <li>Set rsync connection I/O idle timeout to 15 seconds.
! 293: <li>Unify the maximum idle I/O and connect timeouts for RSYNC & HTTPS.
! 294: <li>Rpki-client now performs stricter EE certificate validation:
! 295: <ul>
! 296: <li>Disallow AS Resources extensions in ROA EE certificates.
! 297: <li>Disallow Subject Information Access (SIA) extensions in RPKI
! 298: Signed Checklist (RSC) EE certs.
! 299: <li>Check the resources in ROAs and RSCs against EE certs.
! 300: </ul>
! 301: <li>Improve readability and add various information being printed in
! 302: verbose mode.
! 303: <li>Extend filemode (-f) output and print X.509 certificates in PEM
! 304: format when increased verbosity (-vv) is specified.
! 305: <li>Shorten the RRDP I/O idle timeout.
! 306: <li>Introduce a deadline timer that aborts all repository synchronization
! 307: after seven eights of timeout (-s). With this rpki-client has improved
! 308: chances to complete and produce an output even when a CA is excessivly
! 309: slow.
! 310: <li>Abort a currently running RRDP request process when the per-repository
! 311: timeout is reached.
! 312: <li>Permit multiple AccessDescription entries in SIA X.509 extensions. While
! 313: fetching from secondary locations is not yet supported, rpki-client will
! 314: not treat occurence as a fatal error.
! 315: <li>Resolve a potential for a race condition in non-atomic RRDP deltas.
! 316: <li>Fix some memory leaks.
! 317: <li>Improve compliance with the HTTP protocol specification.
! 318: </ul>
! 319:
! 320: <li>In <a href="https://man.openbsd.org/rpki-client.8">ospfd(8)</a>,
! 321: relax the limitations on what is an acceptable unicast IP. There are no
! 322: more experiments in IPv4 and so there is less reason for network
! 323: daemons to deny formerly experimental IP space. Multicast IPs
! 324: (224/4) and loopback (127/8) are stil disallowed.

665: <h3>Notes about the source code</h3>
666: <p>
667: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
668: This file contains everything you need except for the kernel sources,
669: which are in a separate archive.
670: To extract:
671: <blockquote><pre>
672: # <kbd>mkdir -p /usr/src</kbd>
673: # <kbd>cd /usr/src</kbd>
674: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
675: </pre></blockquote>
676: <p>
677: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
678: This file contains all the kernel sources you need to rebuild kernels.
679: To extract:
680: <blockquote><pre>
681: # <kbd>mkdir -p /usr/src/sys</kbd>
682: # <kbd>cd /usr/src</kbd>
683: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
684: </pre></blockquote>
685: <p>
686: Both of these trees are a regular CVS checkout. Using these trees it
687: is possible to get a head-start on using the anoncvs servers as
688: described <a href="anoncvs.html">here</a>.
689: Using these files
690: results in a much faster initial CVS update than you could expect from
691: a fresh checkout of the full OpenBSD source tree.

697: <h3>Ports Tree</h3>
698: <p>
699: A ports tree archive is also provided. To extract:
700: <blockquote><pre>
701: # <kbd>cd /usr</kbd>
702: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
703: </pre></blockquote>
704: <p>
705: Go read the <a href="faq/ports/index.html">ports</a> page
706: if you know nothing about ports
707: at this point. This text is not a manual of how to use ports.
708: Rather, it is a set of notes meant to kickstart the user on the
709: OpenBSD ports system.
710: <p>
711: The <i>ports/</i> directory represents a CVS checkout of our ports.
712: As with our complete source tree, our ports tree is available via
713: <a href="anoncvs.html">AnonCVS</a>.
714: So, in order to keep up to date with the -stable branch, you must make
715: the <i>ports/</i> tree available on a read-write medium and update the tree
716: with a command like:
717: <blockquote><pre>
718: # <kbd>cd /usr/ports</kbd>
719: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_2</kbd>
720: </pre></blockquote>
721: <p>
722: [Of course, you must replace the server name here with a nearby anoncvs
723: server.]
724: <p>
725: Note that most ports are available as packages on our mirrors. Updated
726: ports for the 7.2 release will be made available if problems arise.
727: <p>
728: If you're interested in seeing a port added, would like to help out, or just
729: would like to know more, the mailing list
730: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
