For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG to bootstrap to the tip of 16stable/10, and then rebuild without this option. The bootstrap process from 17older version of current is a bit fragile. 18 1920161208 p44 FreeBSD-SA-16:37.libc [revised] 20 21 Fix regressions introduced by SA-16:37.libc. 22 2320161206 p43 FreeBSD-SA-16:36.telnetd 24 FreeBSD-SA-16:37.libc 25 FreeBSD-SA-16:38.bhyve 26 FreeBSD-EN-16:19.tzcode 27 FreeBSD-EN-16:20.tzdata 28 29 Fix possible login(1) argument injection in telnetd(8).

[EN-15:20] 160 16120151026: p23 FreeBSD-SA-15:25.ntp 162 163 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 164 165 The configuration file syntax has been changed, thus mergemaster 166 run is recommended. Now the "kod" parameter requires "limited" 167 parameter. If the ntp.conf is not updated, the ntpd will run 168 successfully, but with KoD disabled. 169 17020151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 171 Revised patch to address a regression that prevents NIS from working. 172 17320150929: p21 FreeBSD-SA-15:24.rpcbind 174 175 Fix rpcbind(8) remote denial of service.

[EN-15:05] 256 25720150407: p9 FreeBSD-SA-15:04.igmp [revised] 258 FreeBSD-SA-15:07.ntp 259 FreeBSD-SA-15:08.bsdinstall 260 FreeBSD-SA-15:09.ipv6 261 262 Improved patch for SA-15:04.igmp. 263 264 Fix multiple vulnerabilities of ntp.

[SA-15:09] 269 27020150320: p8 271 Fix patch for SA-15:06.openssl. 272 27320150319: p7 FreeBSD-SA-15:06.openssl 274 Fix multiple vulnerabilities in OpenSSL. [SA-15:06] 275 27620150225: p6 FreeBSD-SA-15:04.igmp 277 FreeBSD-EN-15:01.vt 278 FreeBSD-EN-15:02.openssl 279 FreeBSD-EN-15:03.freebsd-update 280 281 Fix integer overflow in IGMP protocol.

[EN-15:03] 288 28920150127: p5 FreeBSD-SA-15:02.kmem 290 FreeBSD-SA-15:03.sctp 291 292 Fix SCTP SCTP_SS_VALUE kernel memory corruption and disclosure 293 vulnerability. [SA-15:02] 294 295 Fix SCTP stream reset vulnerability. [SA-15:03] 296 29720150114: p4 FreeBSD-SA-15:01.openssl 298 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 299 30020141223: p3 FreeBSD-SA-14:31.ntp 301 FreeBSD-EN-14:13.freebsd-update 302 303 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 304 Fix directory deletion issue in freebsd-update. [EN-14:13] 305 30620141217: p2 FreeBSD-SA-14:30.unbound 307 Fix unbound remote denial of service vulnerability. 308 30920141210: p1 FreeBSD-SA-14:27.stdio 310 FreeBSD-SA-14:28.file 311 312 Fix buffer overflow in stdio. [SA-14:27] 313 314 Fix multiple vulnerabilities in file(1) and libmagic(3). 315 [SA-14:28] 316 31720140904: 318 The ofwfb driver, used to provide a graphics console on PowerPC when 319 using vt(4), no longer allows mmap() of all of physical memory. This 320 will prevent Xorg on PowerPC with some ATI graphics cards from 321 initializing properly unless x11-servers/xorg-server is updated to 322 1.12.4_8 or newer. 323 32420140831: 325 The libatf-c and libatf-c++ major versions were downgraded to 0 and 326 1 respectively to match the upstream numbers. They were out of 327 sync because, when they were originally added to FreeBSD, the 328 upstream versions were not respected. These libraries are private 329 and not yet built by default, so renumbering them should be a 330 non-issue. However, unclean source trees will yield broken test 331 programs once the operator executes "make delete-old-libs" after a 332 "make installworld". 333 334 Additionally, the atf-sh binary was made private by moving it into 335 /usr/libexec/. Already-built shell test programs will keep the 336 path to the old binary so they will break after "make delete-old" 337 is run. 338 339 If you are using WITH_TESTS=yes (not the default), wipe the object 340 tree and rebuild from scratch to prevent spurious test failures. 341 This is only needed once: the misnumbered libraries and misplaced 342 binaries have been added to OptionalObsoleteFiles.inc so they will 343 be removed during a clean upgrade. 344 34520140814: 346 The ixgbe tunables now match their sysctl counterparts, for example: 347 hw.ixgbe.enable_aim => hw.ix.enable_aim 348 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 349 35020140801: 351 The NFSv4.1 server committed by r269398 changes the internal 352 function call interfaces used between the NFS and krpc modules. 353 As such, __FreeBSD_version was bumped. 354 35520140729: 356 The default unbound configuration has been modified to address 357 issues with reverse lookups on networks that use private 358 address ranges. If you use the local_unbound service, run 359 "service local_unbound setup" as root to regenerate your 360 configuration, then "service local_unbound reload" to load the 361 new configuration. 362 36320140717: 364 It is no longer necessary to include the dwarf version in your DEBUG 365 options in your kernel config file. The bug that required it to be 366 placed in the config file has bene fixed. DEBUG should now just 367 contain -g. The build system will automatically update things 368 to do the right thing. 369 37020140715: 371 Several ABI breaking changes were merged to CTL and new iSCSI code. 372 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 373 iscsictl need to be rebuilt to work with a new kernel. 374 37520140708: 376 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 377 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 378 which differs from the behaviour controlled by this knob.) 379 38020140608: 381 On i386 and amd64 systems, the onifconsole flag is now set by default 382 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 383 as a login TTY if it is set in the bootloader as an active kernel 384 console. No changes in behavior should result otherwise. To revert to 385 the previous behavior, set ttyu0 to "off" in /etc/ttys. 386 38720140512: 388 Clang and llvm have been upgraded to 3.4.1 release. 389 39020140321: 391 Clang and llvm have been upgraded to 3.4 release. 392 39320140306: 394 If a Makefile in a tests/ directory was auto-generating a Kyuafile 395 instead of providing an explicit one, this would prevent such 396 Makefile from providing its own Kyuafile in the future during 397 NO_CLEAN builds. This has been fixed in the Makefiles but manual 398 intervention is needed to clean an objdir if you use NO_CLEAN: 399 # find /usr/obj -name Kyuafile | xargs rm -f 400 40120140303: 402 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 403 capability mode support. Please note that enabling the feature in 404 kernel is still highly recommended. 405 40620140227: 407 OpenSSH is now built with sandbox support, and will use sandbox as 408 the default privilege separation method. This requires Capsicum 409 capability mode support in kernel. 410 41120140216: 412 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 413 been deprecated and will not be part of FreeBSD 11.0 and later 414 releases. If you use this driver, please consider switching to 415 the nfe(4) driver instead. 416 41720140120: 418 10.0-RELEASE. 419 42020131216: 421 The behavior of gss_pseudo_random() for the krb5 mechanism 422 has changed, for applications requesting a longer random string 423 than produced by the underlying enctype's pseudo-random() function. 424 In particular, the random string produced from a session key of 425 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 426 be different at the 17th octet and later, after this change. 427 The counter used in the PRF+ construction is now encoded as a 428 big-endian integer in accordance with RFC 4402. 429 __FreeBSD_version is bumped to 1000701. 430 43120131108: 432 The WITHOUT_ATF build knob has been removed and its functionality 433 has been subsumed into the more generic WITHOUT_TESTS. If you were 434 using the former to disable the build of the ATF libraries, you 435 should change your settings to use the latter. 436 43720131031: 438 The default version of mtree is nmtree which is obtained from 439 NetBSD. The output is generally the same, but may vary 440 slightly. If you found you need identical output adding 441 "-F freebsd9" to the command line should do the trick. For the 442 time being, the old mtree is available as fmtree. 443 44420131014: 445 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 446 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 447 1.1.4_8 and verify bsdyml not linked in, before running "make 448 delete-old-libs": 449 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 450 or 451 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 452 45320131010: 454 The rc.d/jail script has been updated to support jail(8) 455 configuration file. The "jail_<jname>_*" rc.conf(5) variables 456 for per-jail configuration are automatically converted to 457 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 458 This is transparently backward compatible. See below about some 459 incompatibilities and rc.conf(5) manual page for more details. 460 461 These variables are now deprecated in favor of jail(8) configuration 462 file. One can use "rc.d/jail config <jname>" command to generate 463 a jail(8) configuration file in /var/run/jail.<jname>.conf without 464 running the jail(8) utility. The default pathname of the 465 configuration file is /etc/jail.conf and can be specified by 466 using $jail_conf or $jail_<jname>_conf variables. 467 468 Please note that jail_devfs_ruleset accepts an integer at 469 this moment. Please consider to rewrite the ruleset name 470 with an integer. 471 47220130930: 473 BIND has been removed from the base system. If all you need 474 is a local resolver, simply enable and start the local_unbound 475 service instead. Otherwise, several versions of BIND are 476 available in the ports tree. The dns/bind99 port is one example. 477 478 With this change, nslookup(1) and dig(1) are no longer in the base 479 system. Users should instead use host(1) and drill(1) which are 480 in the base system. Alternatively, nslookup and dig can 481 be obtained by installing the dns/bind-tools port. 482 48320130916: 484 With the addition of unbound(8), a new unbound user is now 485 required during installworld. "mergemaster -p" can be used to 486 add the user prior to installworld, as documented in the handbook. 487 48820130911: 489 OpenSSH is now built with DNSSEC support, and will by default 490 silently trust signed SSHFP records. This can be controlled with 491 the VerifyHostKeyDNS client configuration setting. DNSSEC support 492 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 493 49420130906: 495 The GNU Compiler Collection and C++ standard library (libstdc++) 496 are no longer built by default on platforms where clang is the system 497 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 498 options in src.conf. 499 50020130905: 501 The PROCDESC kernel option is now part of the GENERIC kernel 502 configuration and is required for the rwhod(8) to work. 503 If you are using custom kernel configuration, you should include 504 'options PROCDESC'. 505 50620130905: 507 The API and ABI related to the Capsicum framework was modified 508 in backward incompatible way. The userland libraries and programs 509 have to be recompiled to work with the new kernel. This includes the 510 following libraries and programs, but the whole buildworld is 511 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 512 kdump, procstat, rwho, rwhod, uniq. 513 51420130903: 515 AES-NI intrinsic support has been added to gcc. The AES-NI module 516 has been updated to use this support. A new gcc is required to build 517 the aesni module on both i386 and amd64. 518 51920130821: 520 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 521 Thus "device padlock_rng" and "device rdrand_rng" should be 522 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 523 52420130813: 525 WITH_ICONV has been split into two feature sets. WITH_ICONV now 526 enables just the iconv* functionality and is now on by default. 527 WITH_LIBICONV_COMPAT enables the libiconv api and link time 528 compatability. Set WITHOUT_ICONV to build the old way. 529 If you have been using WITH_ICONV before, you will very likely 530 need to turn on WITH_LIBICONV_COMPAT. 531 53220130806: 533 INVARIANTS option now enables DEBUG for code with OpenSolaris and 534 Illumos origin, including ZFS. If you have INVARIANTS in your 535 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 536 explicitly. 537 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 538 locks if WITNESS option was set. Because that generated a lot of 539 witness(9) reports and all of them were believed to be false 540 positives, this is no longer done. New option OPENSOLARIS_WITNESS 541 can be used to achieve the previous behavior. 542 54320130806: 544 Timer values in IPv6 data structures now use time_uptime instead 545 of time_second. Although this is not a user-visible functional 546 change, userland utilities which directly use them---ndp(8), 547 rtadvd(8), and rtsold(8) in the base system---need to be updated 548 to r253970 or later. 549 55020130802: 551 find -delete can now delete the pathnames given as arguments, 552 instead of only files found below them or if the pathname did 553 not contain any slashes. Formerly, the following error message 554 would result: 555 556 find: -delete: <path>: relative path potentially not safe 557 558 Deleting the pathnames given as arguments can be prevented 559 without error messages using -mindepth 1 or by changing 560 directory and passing "." as argument to find. This works in the 561 old as well as the new version of find. 562 56320130726: 564 Behavior of devfs rules path matching has been changed. 565 Pattern is now always matched against fully qualified devfs 566 path and slash characters must be explicitly matched by 567 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 568 subdirectories must be reviewed. 569 57020130716: 571 The default ARM ABI has changed to the ARM EABI. The old ABI is 572 incompatible with the ARM EABI and all programs and modules will 573 need to be rebuilt to work with a new kernel. 574 575 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 576 577 NOTE: Support for the old ABI will be removed in the future and 578 users are advised to upgrade. 579 58020130709: 581 pkg_install has been disconnected from the build if you really need it 582 you should add WITH_PKGTOOLS in your src.conf(5). 583 58420130709: 585 Most of network statistics structures were changed to be able 586 keep 64-bits counters. Thus all tools, that work with networking 587 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 588 58920130629: 590 Fix targets that run multiple make's to use && rather than ; 591 so that subsequent steps depend on success of previous. 592 593 NOTE: if building 'universe' with -j* on stable/8 or stable/9 594 it would be better to start the build using bmake, to avoid 595 overloading the machine. 596 59720130618: 598 Fix a bug that allowed a tracing process (e.g. gdb) to write 599 to a memory-mapped file in the traced process's address space 600 even if neither the traced process nor the tracing process had 601 write access to that file. 602 60320130615: 604 CVS has been removed from the base system. An exact copy 605 of the code is available from the devel/cvs port. 606 60720130613: 608 Some people report the following error after the switch to bmake: 609 610 make: illegal option -- J 611 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 612 ... 613 *** [buildworld] Error code 2 614 615 this likely due to an old instance of make in 616 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 617 which src/Makefile will use that blindly, if it exists, so if 618 you see the above error: 619 620 rm -rf `make -V MAKEPATH` 621 622 should resolve it. 623 62420130516: 625 Use bmake by default. 626 Whereas before one could choose to build with bmake via 627 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 628 make. The goal is to remove these knobs for 10-RELEASE. 629 630 It is worth noting that bmake (like gmake) treats the command 631 line as the unit of failure, rather than statements within the 632 command line. Thus '(cd some/where && dosomething)' is safer 633 than 'cd some/where; dosomething'. The '()' allows consistent 634 behavior in parallel build. 635 63620130429: 637 Fix a bug that allows NFS clients to issue READDIR on files. 638 63920130426: 640 The WITHOUT_IDEA option has been removed because 641 the IDEA patent expired. 642 64320130426: 644 The sysctl which controls TRIM support under ZFS has been renamed 645 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 646 enabled by default. 647 64820130425: 649 The mergemaster command now uses the default MAKEOBJDIRPREFIX 650 rather than creating it's own in the temporary directory in 651 order allow access to bootstrapped versions of tools such as 652 install and mtree. When upgrading from version of FreeBSD where 653 the install command does not support -l, you will need to 654 install a new mergemaster command if mergemaster -p is required. 655 This can be accomplished with the command (cd src/usr.sbin/mergemaster 656 && make install). 657 65820130404: 659 Legacy ATA stack, disabled and replaced by new CAM-based one since 660 FreeBSD 9.0, completely removed from the sources. Kernel modules 661 atadisk and atapi*, user-level tools atacontrol and burncd are 662 removed. Kernel option `options ATA_CAM` is now permanently enabled 663 and removed. 664 66520130319: 666 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 667 and socketpair(2). Software, in particular Kerberos, may 668 automatically detect and use these during building. The resulting 669 binaries will not work on older kernels. 670 67120130308: 672 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 673 information, see the respective 20130304 entry). 674 67520130304: 676 Recent commits to callout(9) changed the size of struct callout, 677 so the KBI is probably heavily disturbed. Also, some functions 678 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 679 by macros. Every kernel module using it won't load, so rebuild 680 is requested. 681 682 The ctl device has been re-enabled in GENERIC for i386 and amd64, 683 but does not initialize by default (because of the new CTL_DISABLE 684 option) to save memory. To re-enable it, remove the CTL_DISABLE 685 option from the kernel config file or set kern.cam.ctl.disable=0 686 in /boot/loader.conf. 687 68820130301: 689 The ctl device has been disabled in GENERIC for i386 and amd64. 690 This was done due to the extra memory being allocated at system 691 initialisation time by the ctl driver which was only used if 692 a CAM target device was created. This makes a FreeBSD system 693 unusable on 128MB or less of RAM. 694 69520130208: 696 A new compression method (lz4) has been merged to -HEAD. Please 697 refer to zpool-features(7) for more information. 698 699 Please refer to the "ZFS notes" section of this file for information 700 on upgrading boot ZFS pools. 701 70220130129: 703 A BSD-licensed patch(1) variant has been added and is installed 704 as bsdpatch, being the GNU version the default patch. 705 To inverse the logic and use the BSD-licensed one as default, 706 while having the GNU version installed as gnupatch, rebuild 707 and install world with the WITH_BSD_PATCH knob set. 708 70920130121: 710 Due to the use of the new -l option to install(1) during build 711 and install, you must take care not to directly set the INSTALL 712 make variable in your /etc/make.conf, /etc/src.conf, or on the 713 command line. If you wish to use the -C flag for all installs 714 you may be able to add INSTALL+=-C to /etc/make.conf or 715 /etc/src.conf. 716 71720130118: 718 The install(1) option -M has changed meaning and now takes an 719 argument that is a file or path to append logs to. In the 720 unlikely event that -M was the last option on the command line 721 and the command line contained at least two files and a target 722 directory the first file will have logs appended to it. The -M 723 option served little practical purpose in the last decade so its 724 use is expected to be extremely rare. 725 72620121223: 727 After switching to Clang as the default compiler some users of ZFS 728 on i386 systems started to experience stack overflow kernel panics. 729 Please consider using 'options KSTACK_PAGES=4' in such configurations. 730 73120121222: 732 GEOM_LABEL now mangles label names read from file system metadata. 733 Mangling affect labels containing spaces, non-printable characters, 734 '%' or '"'. Device names in /etc/fstab and other places may need to 735 be updated. 736 73720121217: 738 By default, only the 10 most recent kernel dumps will be saved. To 739 restore the previous behaviour (no limit on the number of kernel dumps 740 stored in the dump directory) add the following line to /etc/rc.conf: 741 742 savecore_flags="" 743 74420121201: 745 With the addition of auditdistd(8), a new auditdistd user is now 746 required during installworld. "mergemaster -p" can be used to 747 add the user prior to installworld, as documented in the handbook. 748 74920121117: 750 The sin6_scope_id member variable in struct sockaddr_in6 is now 751 filled by the kernel before passing the structure to the userland via 752 sysctl or routing socket. This means the KAME-specific embedded scope 753 id in sin6_addr.s6_addr[2] is always cleared in userland application. 754 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 755 __FreeBSD_version is bumped to 1000025. 756 75720121105: 758 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 759 This means that the world and kernel will be compiled with clang 760 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 761 and /usr/bin/cpp. To disable this behavior and revert to building 762 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 763 of current may need to bootstrap WITHOUT_CLANG first if the clang 764 build fails (its compatibility window doesn't extend to the 9 stable 765 branch point). 766 76720121102: 768 The IPFIREWALL_FORWARD kernel option has been removed. Its 769 functionality now turned on by default. 770 77120121023: 772 The ZERO_COPY_SOCKET kernel option has been removed and 773 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 774 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 775 mechanism which is not safe and may result in kernel crashes. 776 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 777 driver supports disposeable external page sized mbuf storage. 778 Proper replacements for both zero-copy mechanisms are under 779 consideration and will eventually lead to complete removal 780 of the two kernel options. 781 78220121023: 783 The IPv4 network stack has been converted to network byte 784 order. The following modules need to be recompiled together 785 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 786 pf(4), ipfw(4), ng_ipfw(4), stf(4). 787 78820121022: 789 Support for non-MPSAFE filesystems was removed from VFS. The 790 VFS_VERSION was bumped, all filesystem modules shall be 791 recompiled. 792 79320121018: 794 All the non-MPSAFE filesystems have been disconnected from 795 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 796 portalfs, smbfs, xfs. 797 79820121016: 799 The interface cloning API and ABI has changed. The following 800 modules need to be recompiled together with kernel: 801 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 802 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 803 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 804 80520121015: 806 The sdhci driver was split in two parts: sdhci (generic SD Host 807 Controller logic) and sdhci_pci (actual hardware driver). 808 No kernel config modifications are required, but if you 809 load sdhc as a module you must switch to sdhci_pci instead. 810 81120121014: 812 Import the FUSE kernel and userland support into base system. 813 81420121013: 815 The GNU sort(1) program has been removed since the BSD-licensed 816 sort(1) has been the default for quite some time and no serious 817 problems have been reported. The corresponding WITH_GNU_SORT 818 knob has also gone. 819 82020121006: 821 The pfil(9) API/ABI for AF_INET family has been changed. Packet 822 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 823 with new kernel. 824 82520121001: 826 The net80211(4) ABI has been changed to allow for improved driver 827 PS-POLL and power-save support. All wireless drivers need to be 828 recompiled to work with the new kernel. 829 83020120913: 831 The random(4) support for the VIA hardware random number 832 generator (`PADLOCK') is no longer enabled unconditionally. 833 Add the padlock_rng device in the custom kernel config if 834 needed. The GENERIC kernels on i386 and amd64 do include the 835 device, so the change only affects the custom kernel 836 configurations. 837 83820120908: 839 The pf(4) packet filter ABI has been changed. pfctl(8) and 840 snmp_pf module need to be recompiled to work with new kernel. 841 84220120828: 843 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 844 to -HEAD. Pools that have empty_bpobj in active state can not be 845 imported read-write with ZFS implementations that do not support 846 this feature. For more information read the zpool-features(5) 847 manual page. 848 84920120727: 850 The sparc64 ZFS loader has been changed to no longer try to auto- 851 detect ZFS providers based on diskN aliases but now requires these 852 to be explicitly listed in the OFW boot-device environment variable. 853 85420120712: 855 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 856 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 857 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 858 85920120712: 860 The following sysctls and tunables have been renamed for consistency 861 with other variables: 862 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 863 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 864 86520120628: 866 The sort utility has been replaced with BSD sort. For now, GNU sort 867 is also available as "gnusort" or the default can be set back to 868 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 869 installed as "bsdsort". 870 87120120611: 872 A new version of ZFS (pool version 5000) has been merged to -HEAD. 873 Starting with this version the old system of ZFS pool versioning 874 is superseded by "feature flags". This concept enables forward 875 compatibility against certain future changes in functionality of ZFS 876 pools. The first read-only compatible "feature flag" for ZFS pools 877 is named "com.delphix:async_destroy". For more information 878 read the new zpool-features(5) manual page. 879 Please refer to the "ZFS notes" section of this file for information 880 on upgrading boot ZFS pools. 881 88220120417: 883 The malloc(3) implementation embedded in libc now uses sources imported 884 as contrib/jemalloc. The most disruptive API change is to 885 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 886 delete it prior to installworld, and optionally re-create it using the 887 new format after rebooting. See malloc.conf(5) for details 888 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 889 NAMESPACE section). 890 89120120328: 892 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 893 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 894 now spelled mips. This is to aid compatibility with third-party 895 software that expects this naming scheme in uname(3). Little-endian 896 settings are unchanged. If you are updating a big-endian mips64 machine 897 from before this change, you may need to set MACHINE_ARCH=mips64 in 898 your environment before the new build system will recognize your machine. 899 90020120306: 901 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 902 platforms. 903 90420120229: 905 Now unix domain sockets behave "as expected" on nullfs(5). Previously 906 nullfs(5) did not pass through all behaviours to the underlying layer, 907 as a result if we bound to a socket on the lower layer we could connect 908 only to the lower path; if we bound to the upper layer we could connect 909 only to the upper path. The new behavior is one can connect to both the 910 lower and the upper paths regardless what layer path one binds to. 911 91220120211: 913 The getifaddrs upgrade path broken with 20111215 has been restored. 914 If you have upgraded in between 20111215 and 20120209 you need to 915 recompile libc again with your kernel. You still need to recompile 916 world to be able to configure CARP but this restriction already 917 comes from 20111215. 918 91920120114: 920 The set_rcvar() function has been removed from /etc/rc.subr. All 921 base and ports rc.d scripts have been updated, so if you have a 922 port installed with a script in /usr/local/etc/rc.d you can either 923 hand-edit the rcvar= line, or reinstall the port. 924 925 An easy way to handle the mass-update of /etc/rc.d: 926 rm /etc/rc.d/* && mergemaster -i 927 92820120109: 929 panic(9) now stops other CPUs in the SMP systems, disables interrupts 930 on the current CPU and prevents other threads from running. 931 This behavior can be reverted using the kern.stop_scheduler_on_panic 932 tunable/sysctl. 933 The new behavior can be incompatible with kern.sync_on_panic. 934 93520111215: 936 The carp(4) facility has been changed significantly. Configuration 937 of the CARP protocol via ifconfig(8) has changed, as well as format 938 of CARP events submitted to devd(8) has changed. See manual pages 939 for more information. The arpbalance feature of carp(4) is currently 940 not supported anymore. 941 942 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 943 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 944 need to be recompiled. 945 94620111122: 947 The acpi_wmi(4) status device /dev/wmistat has been renamed to 948 /dev/wmistat0. 949 95020111108: 951 The option VFS_ALLOW_NONMPSAFE option has been added in order to 952 explicitely support non-MPSAFE filesystems. 953 It is on by default for all supported platform at this present 954 time. 955 95620111101: 957 The broken amd(4) driver has been replaced with esp(4) in the amd64, 958 i386 and pc98 GENERIC kernel configuration files. 959 96020110930: 961 sysinstall has been removed 962 96320110923: 964 The stable/9 branch created in subversion. This corresponds to the 965 RELENG_9 branch in CVS. 966 96720110913: 968 This commit modifies vfs_register() so that it uses a hash 969 calculation to set vfc_typenum, which is enabled by default. 970 The first time a system is booted after this change, the 971 vfc_typenum values will change for all file systems. The 972 main effect of this is a change to the NFS server file handles 973 for file systems that use vfc_typenum in their fsid, such as ZFS. 974 It will, however, prevent vfc_typenum from changing when file 975 systems are loaded in a different order for subsequent reboots. 976 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 977 until you are ready to remount all NFS clients after a reboot. 978 97920110828: 980 Bump the shared library version numbers for libraries that 981 do not use symbol versioning, have changed the ABI compared 982 to stable/8 and which shared library version was not bumped. 983 Done as part of 9.0-RELEASE cycle. 984 98520110815: 986 During the merge of Capsicum features, the fget(9) KPI was modified. 987 This may require the rebuilding of out-of-tree device drivers -- 988 issues have been reported specifically with the nVidia device driver. 989 __FreeBSD_version is bumped to 900041. 990 991 Also, there is a period between 20110811 and 20110814 where the 992 special devices /dev/{stdin,stdout,stderr} did not work correctly. 993 Building world from a kernel during that window may not work. 994 99520110628: 996 The packet filter (pf) code has been updated to OpenBSD 4.5. 997 You need to update userland tools to be in sync with kernel. 998 This update breaks backward compatibility with earlier pfsync(4) 999 versions. Care must be taken when updating redundant firewall setups. 1000 100120110608: 1002 The following sysctls and tunables are retired on x86 platforms: 1003 machdep.hlt_cpus 1004 machdep.hlt_logical_cpus 1005 The following sysctl is retired: 1006 machdep.hyperthreading_allowed 1007 The sysctls were supposed to provide a way to dynamically offline and 1008 online selected CPUs on x86 platforms, but the implementation has not 1009 been reliable especially with SCHED_ULE scheduler. 1010 machdep.hyperthreading_allowed tunable is still available to ignore 1011 hyperthreading CPUs at OS level. 1012 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 1013 where X is an APIC ID of a CPU. Be advised, though, that disabling 1014 CPUs in non-uniform fashion will result in non-uniform topology and 1015 may lead to sub-optimal system performance with SCHED_ULE, which is 1016 a default scheduler. 1017 101820110607: 1019 cpumask_t type is retired and cpuset_t is used in order to describe 1020 a mask of CPUs. 1021 102220110531: 1023 Changes to ifconfig(8) for dynamic address family detection mandate 1024 that you are running a kernel of 20110525 or later. Make sure to 1025 follow the update procedure to boot a new kernel before installing 1026 world. 1027 102820110513: 1029 Support for sun4v architecture is officially dropped 1030 103120110503: 1032 Several KPI breaking changes have been committed to the mii(4) layer, 1033 the PHY drivers and consequently some Ethernet drivers using mii(4). 1034 This means that miibus.ko and the modules of the affected Ethernet 1035 drivers need to be recompiled. 1036 1037 Note to kernel developers: Given that the OUI bit reversion problem 1038 was fixed as part of these changes all mii(4) commits related to OUIs, 1039 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1040 handling, no longer can be merged verbatim to stable/8 and previous 1041 branches. 1042 104320110430: 1044 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1045 into their kernel configurations along with 'device pci'. 1046 104720110427: 1048 The default NFS client is now the new NFS client, so fstype "newnfs" 1049 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1050 Although mounts via fstype "nfs" will usually work without userland 1051 changes, it is recommended that the mount(8) and mount_nfs(8) 1052 commands be rebuilt from sources and that a link to mount_nfs called 1053 mount_oldnfs be created. The new client is compiled into the 1054 kernel with "options NFSCL" and this is needed for diskless root 1055 file systems. The GENERIC kernel configs have been changed to use 1056 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1057 To use the regular/old client, you can "mount -t oldnfs ...". For 1058 a diskless root file system, you must also include a line like: 1059 1060 vfs.root.mountfrom="oldnfs:" 1061 1062 in the boot/loader.conf on the root fs on the NFS server to make 1063 a diskless root fs use the old client. 1064 106520110424: 1066 The GENERIC kernels for all architectures now default to the new 1067 CAM-based ATA stack. It means that all legacy ATA drivers were 1068 removed and replaced by respective CAM drivers. If you are using 1069 ATA device names in /etc/fstab or other places, make sure to update 1070 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1071 where 'Y's are the sequential numbers starting from zero for each type 1072 in order of detection, unless configured otherwise with tunables, 1073 see cam(4)). There will be symbolic links created in /dev/ to map 1074 old adX devices to the respective adaY. They should provide basic 1075 compatibility for file systems mounting in most cases, but they do 1076 not support old user-level APIs and do not have respective providers 1077 in GEOM. Consider using updated management tools with new device names. 1078 1079 It is possible to load devices ahci, ata, siis and mvs as modules, 1080 but option ATA_CAM should remain in kernel configuration to make ata 1081 module work as CAM driver supporting legacy ATA controllers. Device ata 1082 still can be used in modular fashion (atacore + ...). Modules atadisk 1083 and atapi* are not used and won't affect operation in ATA_CAM mode. 1084 Note that to use CAM-based ATA kernel should include CAM devices 1085 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1086 them are parts of the cam module. 1087 1088 ataraid(4) functionality is now supported by the RAID GEOM class. 1089 To use it you can load geom_raid kernel module and use graid(8) tool 1090 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1091 1092 No kernel config options or code have been removed, so if a problem 1093 arises, please report it and optionally revert to the old ATA stack. 1094 In order to do it you can remove from the kernel config: 1095 options ATA_CAM 1096 device ahci 1097 device mvs 1098 device siis 1099 , and instead add back: 1100 device atadisk # ATA disk drives 1101 device ataraid # ATA RAID drives 1102 device atapicd # ATAPI CDROM drives 1103 device atapifd # ATAPI floppy drives 1104 device atapist # ATAPI tape drives 1105 110620110423: 1107 The default NFS server has been changed to the new server, which 1108 was referred to as the experimental server. If you need to switch 1109 back to the old NFS server, you must now put the "-o" option on 1110 both the mountd and nfsd commands. This can be done using the 1111 mountd_flags and nfs_server_flags rc.conf variables until an 1112 update to the rc scripts is committed, which is coming soon. 1113 111420110418: 1115 The GNU Objective-C runtime library (libobjc), and other Objective-C 1116 related components have been removed from the base system. If you 1117 require an Objective-C library, please use one of the available ports. 1118 111920110331: 1120 ath(4) has been split into bus- and device- modules. if_ath contains 1121 the HAL, the TX rate control and the network device code. if_ath_pci 1122 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1123 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1124 in order to use ath on everything else. 1125 1126 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1127 need to load if_ath and if_ath_pci for ath(4) operation. 1128 112920110314: 1130 As part of the replacement of sysinstall, the process of building 1131 release media has changed significantly. For details, please re-read 1132 release(7), which has been updated to reflect the new build process. 1133 113420110218: 1135 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1136 is the last available version under GPLv2. It brings a number of new 1137 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1138 4.1 and SSE 4.2), better support for powerpc64, a number of new 1139 directives, and lots of other small improvements. See the ChangeLog 1140 file in contrib/binutils for the full details. 1141 114220110218: 1143 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1144 compliant, and will now use half of hash for authentication. 1145 This will break interoperability with all stacks (including all 1146 actual FreeBSD versions) who implement 1147 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1148 authentication). 1149 The only workaround with such peers is to use another HMAC 1150 algorithm for IPsec ("phase 2") authentication. 1151 115220110207: 1153 Remove the uio_yield prototype and symbol. This function has 1154 been misnamed since it was introduced and should not be 1155 globally exposed with this name. The equivalent functionality 1156 is now available using kern_yield(curthread->td_user_pri). 1157 The function remains undocumented. 1158 115920110112: 1160 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1161 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1162 for scalar sysctls is defined but disabled. Code that needs 1163 UQUAD to pass the type checking that must compile on older 1164 systems where the define is not present can check against 1165 __FreeBSD_version >= 900030. 1166 1167 The system dialog(1) has been replaced with a new version previously 1168 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1169 with the previous version, but the libdialog associated with it has 1170 a largely incompatible API. As such, the original version of libdialog 1171 will be kept temporarily as libodialog, until its base system consumers 1172 are replaced or updated. Bump __FreeBSD_version to 900030. 1173 117420110103: 1175 If you are trying to run make universe on a -stable system, and you get 1176 the following warning: 1177 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1178 unknown. config(8) likely too old." 1179 or something similar to it, then you must upgrade your -stable system 1180 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1181 stable/8) or build the config from the latest stable/8 branch and 1182 install it on your system. 1183 1184 Prior to this date, building a current universe on 8-stable system from 1185 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1186 error in the first kernel build phase. A new config on those old 1187 systems will fix that problem for older versions of -current. 1188 118920101228: 1190 The TCP stack has been modified to allow Khelp modules to interact with 1191 it via helper hook points and store per-connection data in the TCP 1192 control block. Bump __FreeBSD_version to 900029. User space tools that 1193 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1194 be recompiled. 1195 119620101114: 1197 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1198 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1199 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1200 to take advantage of it instead of using custom implementations. This 1201 means that these drivers now no longer unconditionally advertise 1202 support for flow control but only do so if flow control is a selected 1203 media option. This was implemented in the generic support that way in 1204 order to allow flow control to be switched on and off via ifconfig(8) 1205 with the PHY specific default to typically off in order to protect 1206 from unwanted effects. Consequently, if you used flow control with 1207 one of the above mentioned drivers you now need to explicitly enable 1208 it, for example via: 1209 ifconfig bge0 media auto mediaopt flowcontrol 1210 1211 Along with the above mentioned changes generic support for setting 1212 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1213 e1000phy(4) as well as ip1000phy(4) have been converted to take 1214 advantage of it. This means that these drivers now no longer take the 1215 link0 parameter for selecting master mode but the master media option 1216 has to be used instead, for example like in the following: 1217 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1218 1219 Selection of master mode now is also available with all other PHY 1220 drivers supporting 1000baseT. 1221 122220101111: 1223 The TCP stack has received a significant update to add support for 1224 modularised congestion control and generally improve the clarity of 1225 congestion control decisions. Bump __FreeBSD_version to 900025. User 1226 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1227 sockstat) need to be recompiled. 1228 122920101002: 1230 The man(1) utility has been replaced by a new version that no longer 1231 uses /etc/manpath.config. Please consult man.conf(5) for how to 1232 migrate local entries to the new format. 1233 123420100928: 1235 The copyright strings printed by login(1) and sshd(8) at the time of a 1236 new connection have been removed to follow other operating systems and 1237 upstream sshd. 1238 123920100915: 1240 A workaround for a fixed ld bug has been removed in kernel code, 1241 so make sure that your system ld is built from sources after 1242 revision 210245 from 2010-07-19 (r211583 if building head kernel 1243 on stable/8, r211584 for stable/7; both from 2010-08-21). 1244 A symptom of incorrect ld version is different addresses for 1245 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1246 124720100913: 1248 The $ipv6_prefer variable in rc.conf(5) has been split into 1249 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1250 1251 The $ip6addrctl_policy is a variable to choose a pre-defined 1252 address selection policy set by ip6addrctl(8). A value 1253 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1254 default is "AUTO". 1255 1256 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1257 flag (see an entry of 20090926) is set on an interface with no 1258 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1259 security reason. If you want IPv6 link-local address on all 1260 interfaces by default, set this to "YES". 1261 1262 The old ipv6_prefer="YES" is equivalent to 1263 ipv6_activate_all_interfaces="YES" and 1264 ip6addrctl_policy="ipv6_prefer". 1265 126620100913: 1267 DTrace has grown support for userland tracing. Due to this, DTrace is 1268 now i386 and amd64 only. 1269 dtruss(1) is now installed by default on those systems and a new 1270 kernel module is needed for userland tracing: fasttrap. 1271 No changes to your kernel config file are necessary to enable 1272 userland tracing, but you might consider adding 'STRIP=' and 1273 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1274 to have informative userland stack traces in DTrace (ustack). 1275 127620100725: 1277 The acpi_aiboost(4) driver has been removed in favor of the new 1278 aibs(4) driver. You should update your kernel configuration file. 1279 128020100722: 1281 BSD grep has been imported to the base system and it is built by 1282 default. It is completely BSD licensed, highly GNU-compatible, uses 1283 less memory than its GNU counterpart and has a small codebase. 1284 However, it is slower than its GNU counterpart, which is mostly 1285 noticeable for larger searches, for smaller ones it is measurable 1286 but not significant. The reason is complex, the most important factor 1287 is that we lack a modern and efficient regex library and GNU 1288 overcomes this by optimizing the searches internally. Future work 1289 on improving the regex performance is planned, for the meantime, 1290 users that need better performance, can build GNU grep instead by 1291 setting the WITH_GNU_GREP knob. 1292 129320100713: 1294 Due to the import of powerpc64 support, all existing powerpc kernel 1295 configuration files must be updated with a machine directive like this: 1296 machine powerpc powerpc 1297 1298 In addition, an updated config(8) is required to build powerpc kernels 1299 after this change. 1300 130120100713: 1302 A new version of ZFS (version 15) has been merged to -HEAD. 1303 This version uses a python library for the following subcommands: 1304 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1305 For full functionality of these commands the following port must 1306 be installed: sysutils/py-zfs 1307 130820100429: 1309 'vm_page's are now hashed by physical address to an array of mutexes. 1310 Currently this is only used to serialize access to hold_count. Over 1311 time the page queue mutex will be peeled away. This changes the size 1312 of pmap on every architecture. And requires all callers of vm_page_hold 1313 and vm_page_unhold to be updated. 1314 131520100402: 1316 WITH_CTF can now be specified in src.conf (not recommended, there 1317 are some problems with static executables), make.conf (would also 1318 affect ports which do not use GNU make and do not override the 1319 compile targets) or in the kernel config (via "makeoptions 1320 WITH_CTF=yes"). 1321 When WITH_CTF was specified there before this was silently ignored, 1322 so make sure that WITH_CTF is not used in places which could lead 1323 to unwanted behavior. 1324 132520100311: 1326 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1327 to allow 32-bit compatibility on non-x86 platforms. All kernel 1328 configurations on amd64 and ia64 platforms using these options must 1329 be modified accordingly. 1330 133120100113: 1332 The utmp user accounting database has been replaced with utmpx, 1333 the user accounting interface standardized by POSIX. 1334 Unfortunately the semantics of utmp and utmpx don't match, 1335 making it practically impossible to support both interfaces. 1336 The user accounting database is used by tools like finger(1), 1337 last(1), talk(1), w(1) and ac(8). 1338 1339 All applications in the base system use utmpx. This means only 1340 local binaries (e.g. from the ports tree) may still use these 1341 utmp database files. These applications must be rebuilt to make 1342 use of utmpx. 1343 1344 After the system has been upgraded, it is safe to remove the old 1345 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1346 assuming their contents is of no importance anymore. Old wtmp 1347 databases can only be used by last(1) and ac(8) after they have 1348 been converted to the new format using wtmpcvt(1). 1349 135020100108: 1351 Introduce the kernel thread "deadlock resolver" (which can be enabled 1352 via the DEADLKRES option, see NOTES for more details) and the 1353 sleepq_type() function for sleepqueues. 1354 135520091202: 1356 The rc.firewall and rc.firewall6 were unified, and 1357 rc.firewall6 and rc.d/ip6fw were removed. 1358 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1359 variables are obsoleted. Instead, the following new rc 1360 variables are added to rc.d/ipfw: 1361 1362 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1363 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1364 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1365 1366 The meanings correspond to the relevant IPv4 variables. 1367 136820091125: 1369 8.0-RELEASE. 1370 137120091113: 1372 The default terminal emulation for syscons(4) has been changed 1373 from cons25 to xterm on all platforms except pc98. This means 1374 that the /etc/ttys file needs to be updated to ensure correct 1375 operation of applications on the console. 1376 1377 The terminal emulation style can be toggled per window by using 1378 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1379 options can be used to change the compile-time default back to 1380 cons25. 1381 1382 To prevent graphical artifacts, make sure the TERM environment 1383 variable is set to match the terminal emulation that is being 1384 performed by syscons(4). 1385 138620091109: 1387 The layout of the structure ieee80211req_scan_result has changed. 1388 Applications that require wireless scan results (e.g. ifconfig(8)) 1389 from net80211 need to be recompiled. 1390 1391 Applications such as wpa_supplicant(8) may require a full world 1392 build without using NO_CLEAN in order to get synchronized with the 1393 new structure. 1394 139520091025: 1396 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1397 There's one kernel module for each firmware. Adding "device iwnfw" 1398 to the kernel configuration file means including all three firmware 1399 images inside the kernel. If you want to include just the one for 1400 your wireless card, use the devices iwn4965fw, iwn5000fw or 1401 iwn5150fw. 1402 140320090926: 1404 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1405 into rc.d/netif. The changes are the following: 1406 1407 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1408 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1409 Note that both variables need the "inet6" keyword at the head. 1410 1411 Do not set $ipv6_network_interfaces manually if you do not 1412 understand what you are doing. It is not needed in most cases. 1413 1414 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1415 they are obsolete. 1416 1417 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1418 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1419 1420 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1421 all configured interfaces have "inet6 accept_rtadv" in the 1422 $ifconfig_IF_ipv6. These are for backward compatibility. 1423 1424 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1425 functionality of interfaces with no corresponding 1426 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1427 and the default address selection policy of ip6addrctl(8) 1428 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1429 Note that if you want to configure IPv6 functionality on the 1430 disabled interfaces after boot, first you need to clear the flag by 1431 using ifconfig(8) like: 1432 1433 ifconfig em0 inet6 -ifdisabled 1434 1435 If YES, the default address selection policy is set as 1436 IPv6-preferred. 1437 1438 The default value of $ipv6_prefer is NO. 1439 1440 4. If your system need to receive Router Advertisement messages, 1441 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1442 scripts automatically invoke rtsol(8) when the interface becomes 1443 UP. The Router Advertisement messages are used for SLAAC 1444 (State-Less Address AutoConfiguration). 1445 144620090922: 1447 802.11s D3.03 support was committed. This is incompatible with the 1448 previous code, which was based on D3.0. 1449 145020090912: 1451 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1452 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1453 control whether accepting Router Advertisement messages or not. 1454 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1455 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1456 The ifconfig(8) utility now supports these flags. 1457 145820090910: 1459 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1460 mount(8) and -a option for df(1) to see them. 1461 146220090825: 1463 The old tunable hw.bus.devctl_disable has been superseded by 1464 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1465 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1466 is 1000. 1467 146820090813: 1469 Remove the option STOP_NMI. The default action is now to use NMI only 1470 for KDB via the newly introduced function stop_cpus_hard() and 1471 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1472 147320090803: 1474 The stable/8 branch created in subversion. This corresponds to the 1475 RELENG_8 branch in CVS. 1476 147720090719: 1478 Bump the shared library version numbers for all libraries that do not 1479 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1480 __FreeBSD_version to 800105. 1481 148220090714: 1483 Due to changes in the implementation of virtual network stack support, 1484 all network-related kernel modules must be recompiled. As this change 1485 breaks the ABI, bump __FreeBSD_version to 800104. 1486 148720090713: 1488 The TOE interface to the TCP syncache has been modified to remove 1489 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1490 The cxgb driver is the only TOE consumer affected by this change, and 1491 needs to be recompiled along with the kernel. As this change breaks 1492 the ABI, bump __FreeBSD_version to 800103. 1493 149420090712: 1495 Padding has been added to struct tcpcb, sackhint and tcpstat in 1496 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1497 maintaining the ABI. However, this change breaks the ABI, so bump 1498 __FreeBSD_version to 800102. User space tools that rely on the size of 1499 any of these structs (e.g. sockstat) need to be recompiled. 1500 150120090630: 1502 The NFS_LEGACYRPC option has been removed along with the old kernel 1503 RPC implementation that this option selected. Kernel configurations 1504 may need to be adjusted. 1505 150620090629: 1507 The network interface device nodes at /dev/net/<interface> have been 1508 removed. All ioctl operations can be performed the normal way using 1509 routing sockets. The kqueue functionality can generally be replaced 1510 with routing sockets. 1511 151220090628: 1513 The documentation from the FreeBSD Documentation Project (Handbook, 1514 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1515 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1516 151720090624: 1518 The ABI of various structures related to the SYSV IPC API have been 1519 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1520 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1521 800100. 1522 152320090622: 1524 Layout of struct vnet has changed as routing related variables were 1525 moved to their own Vimage module. Modules need to be recompiled. Bump 1526 __FreeBSD_version to 800099. 1527 152820090619: 1529 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1530 respectively. As long as no more than 16 groups per process are used, 1531 no changes should be visible. When more than 16 groups are used, old 1532 binaries may fail if they call getgroups() or getgrouplist() with 1533 statically sized storage. Recompiling will work around this, but 1534 applications should be modified to use dynamically allocated storage 1535 for group arrays as POSIX.1-2008 does not cap an implementation's 1536 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1537 1538 NFS and portalfs mounts may also be affected as the list of groups is 1539 truncated to 16. Users of NFS who use more than 16 groups, should 1540 take care that negative group permissions are not used on the exported 1541 file systems as they will not be reliable unless a GSSAPI based 1542 authentication method is used. 1543 154420090616: 1545 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1546 option compiles in the support for adaptive spinning for lockmgrs 1547 which want to enable it. The lockinit() function now accepts the flag 1548 LK_ADAPTIVE in order to make the lock object subject to adaptive 1549 spinning when both held in write and read mode. 1550 155120090613: 1552 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1553 changed. User applications that use this ioctl need to be rebuilt. 1554 155520090611: 1556 The layout of struct thread has changed. Kernel and modules need to 1557 be rebuilt. 1558 155920090608: 1560 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1561 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1562 156320090602: 1564 window(1) has been removed from the base system. It can now be 1565 installed from ports. The port is called misc/window. 1566 156720090601: 1568 The way we are storing and accessing `routing table' entries has 1569 changed. Programs reading the FIB, like netstat, need to be 1570 re-compiled. 1571 157220090601: 1573 A new netisr implementation has been added for FreeBSD 8. Network 1574 file system modules, such as igmp, ipdivert, and others, should be 1575 rebuilt. 1576 Bump __FreeBSD_version to 800096. 1577 157820090530: 1579 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1580 more valid. 1581 158220090530: 1583 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1584 Bump __FreeBSD_version to 800094. 1585 158620090529: 1587 Add mnt_xflag field to 'struct mount'. File system modules need to be 1588 rebuilt. 1589 Bump __FreeBSD_version to 800093. 1590 159120090528: 1592 The compiling option ADAPTIVE_SX has been retired while it has been 1593 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1594 The KPI for sx_init_flags() changes as accepting flags: 1595 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1596 been introduced in order to handle the reversed logic. 1597 Bump __FreeBSD_version to 800092. 1598 159920090527: 1600 Add support for hierarchical jails. Remove global securelevel. 1601 Bump __FreeBSD_version to 800091. 1602 160320090523: 1604 The layout of struct vnet_net has changed, therefore modules 1605 need to be rebuilt. 1606 Bump __FreeBSD_version to 800090. 1607 160820090523: 1609 The newly imported zic(8) produces a new format in the output. Please 1610 run tzsetup(8) to install the newly created data to /etc/localtime. 1611 161220090520: 1613 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1614 hw.usb.* and is now consistent again with previous releases. 1615 161620090520: 1617 802.11 monitor mode support was revised and driver api's were changed. 1618 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1619 of DLT_IEEE802_11. No user-visible data structures were changed but 1620 applications that use DLT_IEEE802_11 may require changes. 1621 Bump __FreeBSD_version to 800088. 1622 162320090430: 1624 The layout of the following structs has changed: sysctl_oid, 1625 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1626 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1627 panics may be experienced. World rebuild is required for 1628 correctly checking networking state from userland. 1629 Bump __FreeBSD_version to 800085. 1630 163120090429: 1632 MLDv2 and Source-Specific Multicast (SSM) have been merged 1633 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1634 The implementation of SSM within FreeBSD's IPv6 stack closely 1635 follows the IPv4 implementation. 1636 1637 For kernel developers: 1638 1639 * The most important changes are that the ip6_output() and 1640 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1641 and this lock has been downgraded to a non-recursive mutex. 1642 1643 * As with the changes to the IPv4 stack to support SSM, filtering 1644 of inbound multicast traffic must now be performed by transport 1645 protocols within the IPv6 stack. This does not apply to TCP and 1646 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1647 1648 * The KPIs used by IPv6 multicast are similar to those used by 1649 the IPv4 stack, with the following differences: 1650 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1651 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1652 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1653 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1654 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1655 for MLDv1 have an additional 'timer' argument which is used to 1656 jitter the initial membership report for the solicited-node 1657 multicast membership on-link. 1658 * This is not strictly needed for MLDv2, which already jitters 1659 its report transmissions. However, the 'timer' argument is 1660 preserved in case MLDv1 is active on the interface. 1661 1662 * The KAME linked-list based IPv6 membership implementation has 1663 been refactored to use a vector similar to that used by the IPv4 1664 stack. 1665 Code which maintains a list of its own multicast memberships 1666 internally, e.g. carp, has been updated to reflect the new 1667 semantics. 1668 1669 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1670 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1671 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1672 implementation constraint which needs to be addressed in HEAD. 1673 1674 For application developers: 1675 1676 * The changes are broadly similar to those made for the IPv4 1677 stack. 1678 1679 * The use of IPv4 and IPv6 multicast socket options on the same 1680 socket, using mapped addresses, HAS NOT been tested or supported. 1681 1682 * There are a number of issues with the implementation of various 1683 IPv6 multicast APIs which need to be resolved in the API surface 1684 before the implementation is fully compatible with KAME userland 1685 use, and these are mostly to do with interface index treatment. 1686 1687 * The literature available discusses the use of either the delta / ASM 1688 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1689 using setsourcefilter(3)/getsourcefilter(3). For more information 1690 please refer to RFC 3768, 'Socket Interface Extensions for 1691 Multicast Source Filters'. 1692 1693 * Applications which use the published RFC 3678 APIs should be fine. 1694 1695 For systems administrators: 1696 1697 * The mtest(8) utility has been refactored to support IPv6, in 1698 addition to IPv4. Interface addresses are no longer accepted 1699 as arguments, their names must be used instead. The utility 1700 will map the interface name to its first IPv4 address as 1701 returned by getifaddrs(3). 1702 1703 * The ifmcstat(8) utility has also been updated to print the MLDv2 1704 endpoint state and source filter lists via sysctl(3). 1705 1706 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1707 loopback of IPv6 multicast datagrams by default; it defaults to 1 1708 to preserve the existing behaviour. Disabling multicast loopback is 1709 recommended for optimal system performance. 1710 1711 * The IPv6 MROUTING code has been changed to examine this sysctl 1712 instead of attempting to perform a group lookup before looping 1713 back forwarded datagrams. 1714 1715 Bump __FreeBSD_version to 800084. 1716 171720090422: 1718 Implement low-level Bluetooth HCI API. 1719 Bump __FreeBSD_version to 800083. 1720 172120090419: 1722 The layout of struct malloc_type, used by modules to register new 1723 memory allocation types, has changed. Most modules will need to 1724 be rebuilt or panics may be experienced. 1725 Bump __FreeBSD_version to 800081. 1726 172720090415: 1728 Anticipate overflowing inp_flags - add inp_flags2. 1729 This changes most offsets in inpcb, so checking v4 connection 1730 state will require a world rebuild. 1731 Bump __FreeBSD_version to 800080. 1732 173320090415: 1734 Add an llentry to struct route and struct route_in6. Modules 1735 embedding a struct route will need to be recompiled. 1736 Bump __FreeBSD_version to 800079. 1737 173820090414: 1739 The size of rt_metrics_lite and by extension rtentry has changed. 1740 Networking administration apps will need to be recompiled. 1741 The route command now supports show as an alias for get, weighting 1742 of routes, sticky and nostick flags to alter the behavior of stateful 1743 load balancing. 1744 Bump __FreeBSD_version to 800078. 1745 174620090408: 1747 Do not use Giant for kbdmux(4) locking. This is wrong and 1748 apparently causing more problems than it solves. This will 1749 re-open the issue where interrupt handlers may race with 1750 kbdmux(4) in polling mode. Typical symptoms include (but 1751 not limited to) duplicated and/or missing characters when 1752 low level console functions (such as gets) are used while 1753 interrupts are enabled (for example geli password prompt, 1754 mountroot prompt etc.). Disabling kbdmux(4) may help. 1755 175620090407: 1757 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1758 kernel modules referencing any of the above need to be recompiled. 1759 Bump __FreeBSD_version to 800075. 1760 176120090320: 1762 GEOM_PART has become the default partition slicer for storage devices, 1763 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1764 introduces some changes: 1765 1766 MSDOS/EBR: the devices created from MSDOS extended partition entries 1767 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1768 to devices with offset-based names. fstabs may need to be modified. 1769 1770 BSD: the "geometry does not match label" warning is harmless in most 1771 cases but it points to problems in file system misalignment with 1772 disk geometry. The "c" partition is now implicit, covers the whole 1773 top-level drive and cannot be (mis)used by users. 1774 1775 General: Kernel dumps are now not allowed to be written to devices 1776 whose partition types indicate they are meant to be used for file 1777 systems (or, in case of MSDOS partitions, as something else than 1778 the "386BSD" type). 1779 1780 Most of these changes date approximately from 200812. 1781 178220090319: 1783 The uscanner(4) driver has been removed from the kernel. This follows 1784 Linux removing theirs in 2.6 and making libusb the default interface 1785 (supported by sane). 1786 178720090319: 1788 The multicast forwarding code has been cleaned up. netstat(1) 1789 only relies on KVM now for printing bandwidth upcall meters. 1790 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1791 ip6_mroute_mod respectively. The config(5) options for statically 1792 compiling this code remain the same, i.e. 'options MROUTING'. 1793 179420090315: 1795 Support for the IFF_NEEDSGIANT network interface flag has been 1796 removed, which means that non-MPSAFE network device drivers are no 1797 longer supported. In particular, if_ar, if_sr, and network device 1798 drivers from the old (legacy) USB stack can no longer be built or 1799 used. 1800 180120090313: 1802 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1803 a bunch of new language catalog files have also been added. 1804 This means that some common libc messages are now localized and 1805 they depend on the LC_MESSAGES environmental variable. 1806 180720090313: 1808 The k8temp(4) driver has been renamed to amdtemp(4) since 1809 support for Family 10 and Family 11 CPU families was added. 1810 181120090309: 1812 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1813 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1814 1815 For kernel developers, the most important changes are that the 1816 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1817 and this lock has been downgraded to a non-recursive mutex. 1818 1819 Transport protocols (UDP, Raw IP) are now responsible for filtering 1820 inbound multicast traffic according to group membership and source 1821 filters. The imo_multicast_filter() KPI exists for this purpose. 1822 Transports which do not use multicast (SCTP, TCP) already reject 1823 multicast by default. Forwarding and receive performance may improve 1824 as a mutex acquisition is no longer needed in the ip_input() 1825 low-level input path. in_addmulti() and in_delmulti() are shimmed 1826 to new KPIs which exist to support SSM in-kernel. 1827 1828 For application developers, it is recommended that loopback of 1829 multicast datagrams be disabled for best performance, as this 1830 will still cause the lock to be taken for each looped-back 1831 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1832 be tuned to 0 to disable loopback by default; it defaults to 1 1833 to preserve the existing behaviour. 1834 1835 For systems administrators, to obtain best performance with 1836 multicast reception and multiple groups, it is always recommended 1837 that a card with a suitably precise hash filter is used. Hash 1838 collisions will still result in the lock being taken within the 1839 transport protocol input path to check group membership. 1840 1841 If deploying FreeBSD in an environment with IGMP snooping switches, 1842 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1843 enabled; this forces 224.0.0.0/24 group membership to be announced 1844 via IGMP. 1845 1846 The size of 'struct igmpstat' has changed; netstat needs to be 1847 recompiled to reflect this. 1848 Bump __FreeBSD_version to 800070. 1849 185020090309: 1851 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1852 updated to use it. This requires a buildworld/installworld in order to 1853 update the library and dependencies (usbconfig, etc). Its advisable to 1854 rebuild all ports which uses libusb. More specific directions are given 1855 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1856 libusb are no longer required and can be removed. 1857 185820090302: 1859 A workaround is committed to allow the creation of System V shared 1860 memory segment of size > 2 GB on the 64-bit architectures. 1861 Due to a limitation of the existing ABI, the shm_segsz member 1862 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1863 wrong for large segments. Note that limits must be explicitly 1864 raised to allow such segments to be created. 1865 186620090301: 1867 The layout of struct ifnet has changed, requiring a rebuild of all 1868 network device driver modules. 1869 187020090227: 1871 The /dev handling for the new USB stack has changed, a 1872 buildworld/installworld is required for libusb20. 1873 187420090223: 1875 The new USB2 stack has now been permanently moved in and all kernel and 1876 module names reverted to their previous values (eg, usb, ehci, ohci, 1877 ums, ...). The old usb stack can be compiled in by prefixing the name 1878 with the letter 'o', the old usb modules have been removed. 1879 Updating entry 20090216 for xorg and 20090215 for libmap may still 1880 apply. 1881 188220090217: 1883 The rc.conf(5) option if_up_delay has been renamed to 1884 defaultroute_delay to better reflect its purpose. If you have 1885 customized this setting in /etc/rc.conf you need to update it to 1886 use the new name. 1887 188820090216: 1889 xorg 7.4 wants to configure its input devices via hald which does not 1890 yet work with USB2. If the keyboard/mouse does not work in xorg then 1891 add 1892 Option "AllowEmptyInput" "off" 1893 to your ServerLayout section. This will cause X to use the configured 1894 kbd and mouse sections from your xorg.conf. 1895 189620090215: 1897 The GENERIC kernels for all architectures now default to the new USB2 1898 stack. No kernel config options or code have been removed so if a 1899 problem arises please report it and optionally revert to the old USB 1900 stack. If you are loading USB kernel modules or have a custom kernel 1901 that includes GENERIC then ensure that usb names are also changed over, 1902 eg uftdi -> usb2_serial_ftdi. 1903 1904 Older programs linked against the ports libusb 0.1 need to be 1905 redirected to the new stack's libusb20. /etc/libmap.conf can 1906 be used for this: 1907 # Map old usb library to new one for usb2 stack 1908 libusb-0.1.so.8 libusb20.so.1 1909 191020090209: 1911 All USB ethernet devices now attach as interfaces under the name ueN 1912 (eg. ue0). This is to provide a predictable name as vendors often 1913 change usb chipsets in a product without notice. 1914 191520090203: 1916 The ichsmb(4) driver has been changed to require SMBus slave 1917 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1918 All of the other SMBus controller drivers require left-justified 1919 slave addresses, so this change makes all the drivers provide the 1920 same interface. 1921 192220090201: 1923 INET6 statistics (struct ip6stat) was updated. 1924 netstat(1) needs to be recompiled. 1925 192620090119: 1927 NTFS has been removed from GENERIC kernel on amd64 to match 1928 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1929 will load ntfs.ko module automatically when NTFS support is 1930 actually needed, unless ntfs.ko is not installed or security 1931 level prohibits loading kernel modules. If either is the case, 1932 "options NTFS" has to be added into kernel config. 1933 193420090115: 1935 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1936 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1937 800061. User space tools that rely on the size of struct tcpcb in 1938 tcp_var.h (e.g. sockstat) need to be recompiled. 1939 194020081225: 1941 ng_tty(4) module updated to match the new TTY subsystem. 1942 Due to API change, user-level applications must be updated. 1943 New API support added to mpd5 CVS and expected to be present 1944 in next mpd5.3 release. 1945 194620081219: 1947 With __FreeBSD_version 800060 the makefs tool is part of 1948 the base system (it was a port). 1949 195020081216: 1951 The afdata and ifnet locks have been changed from mutexes to 1952 rwlocks, network modules will need to be re-compiled. 1953 195420081214: 1955 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1956 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1957 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1958 architecture and 40 bytes on 64-bit architecture. The userland 1959 applications "arp" and "ndp" have been updated accordingly. 1960 The output from "netstat -r" shows only routing entries and 1961 none of the L2 information. 1962 196320081130: 1964 __FreeBSD_version 800057 marks the switchover from the 1965 binary ath hal to source code. Users must add the line: 1966 1967 options AH_SUPPORT_AR5416 1968 1969 to their kernel config files when specifying: 1970 1971 device ath_hal 1972 1973 The ath_hal module no longer exists; the code is now compiled 1974 together with the driver in the ath module. It is now 1975 possible to tailor chip support (i.e. reduce the set of chips 1976 and thereby the code size); consult ath_hal(4) for details. 1977 197820081121: 1979 __FreeBSD_version 800054 adds memory barriers to 1980 <machine/atomic.h>, new interfaces to ifnet to facilitate 1981 multiple hardware transmit queues for cards that support 1982 them, and a lock-less ring-buffer implementation to 1983 enable drivers to more efficiently manage queueing of 1984 packets. 1985 198620081117: 1987 A new version of ZFS (version 13) has been merged to -HEAD. 1988 This version has zpool attribute "listsnapshots" off by 1989 default, which means "zfs list" does not show snapshots, 1990 and is the same as Solaris behavior. 1991 199220081028: 1993 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1994 199520081009: 1996 The uhci, ohci, ehci and slhci USB Host controller drivers have 1997 been put into separate modules. If you load the usb module 1998 separately through loader.conf you will need to load the 1999 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 2000 controller add the following to loader.conf: 2001 2002 uhci_load="YES" 2003 ehci_load="YES" 2004 200520081009: 2006 The ABI used by the PMC toolset has changed. Please keep 2007 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 2008 sync. 2009 201020081009: 2011 atapci kernel module now includes only generic PCI ATA 2012 driver. AHCI driver moved to ataahci kernel module. 2013 All vendor-specific code moved into separate kernel modules: 2014 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 2015 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 2016 atamarvell, atamicron, atanational, atanetcell, atanvidia, 2017 atapromise, ataserverworks, atasiliconimage, atasis, atavia 2018 201920080820: 2020 The TTY subsystem of the kernel has been replaced by a new 2021 implementation, which provides better scalability and an 2022 improved driver model. Most common drivers have been migrated to 2023 the new TTY subsystem, while others have not. The following 2024 drivers have not yet been ported to the new TTY layer: 2025 2026 PCI/ISA: 2027 cy, digi, rc, rp, sio 2028 2029 USB: 2030 ubser, ucycom 2031 2032 Line disciplines: 2033 ng_h4, ng_tty, ppp, sl, snp 2034 2035 Adding these drivers to your kernel configuration file shall 2036 cause compilation to fail. 2037 203820080818: 2039 ntpd has been upgraded to 4.2.4p5. 2040 204120080801: 2042 OpenSSH has been upgraded to 5.1p1. 2043 2044 For many years, FreeBSD's version of OpenSSH preferred DSA 2045 over RSA for host and user authentication keys. With this 2046 upgrade, we've switched to the vendor's default of RSA over 2047 DSA. This may cause upgraded clients to warn about unknown 2048 host keys even for previously known hosts. Users should 2049 follow the usual procedure for verifying host keys before 2050 accepting the RSA key. 2051 2052 This can be circumvented by setting the "HostKeyAlgorithms" 2053 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2054 command line. 2055 2056 Please note that the sequence of keys offered for 2057 authentication has been changed as well. You may want to 2058 specify IdentityFile in a different order to revert this 2059 behavior. 2060 206120080713: 2062 The sio(4) driver has been removed from the i386 and amd64 2063 kernel configuration files. This means uart(4) is now the 2064 default serial port driver on those platforms as well. 2065 2066 To prevent collisions with the sio(4) driver, the uart(4) driver 2067 uses different names for its device nodes. This means the 2068 onboard serial port will now most likely be called "ttyu0" 2069 instead of "ttyd0". You may need to reconfigure applications to 2070 use the new device names. 2071 2072 When using the serial port as a boot console, be sure to update 2073 /boot/device.hints and /etc/ttys before booting the new kernel. 2074 If you forget to do so, you can still manually specify the hints 2075 at the loader prompt: 2076 2077 set hint.uart.0.at="isa" 2078 set hint.uart.0.port="0x3F8" 2079 set hint.uart.0.flags="0x10" 2080 set hint.uart.0.irq="4" 2081 boot -s 2082 208320080609: 2084 The gpt(8) utility has been removed. Use gpart(8) to partition 2085 disks instead. 2086 208720080603: 2088 The version that Linuxulator emulates was changed from 2.4.2 2089 to 2.6.16. If you experience any problems with Linux binaries 2090 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2091 if it fixes the problem contact emulation mailing list. 2092 209320080525: 2094 ISDN4BSD (I4B) was removed from the src tree. You may need to 2095 update a your kernel configuration and remove relevant entries. 2096 209720080509: 2098 I have checked in code to support multiple routing tables. 2099 See the man pages setfib(1) and setfib(2). 2100 This is a hopefully backwards compatible version, 2101 but to make use of it you need to compile your kernel 2102 with options ROUTETABLES=2 (or more up to 16). 2103 210420080420: 2105 The 802.11 wireless support was redone to enable multi-bss 2106 operation on devices that are capable. The underlying device 2107 is no longer used directly but instead wlanX devices are 2108 cloned with ifconfig. This requires changes to rc.conf files. 2109 For example, change: 2110 ifconfig_ath0="WPA DHCP" 2111 to 2112 wlans_ath0=wlan0 2113 ifconfig_wlan0="WPA DHCP" 2114 see rc.conf(5) for more details. In addition, mergemaster of 2115 /etc/rc.d is highly recommended. Simultaneous update of userland 2116 and kernel wouldn't hurt either. 2117 2118 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2119 modules were merged into the base wlan module. All references 2120 to these modules (e.g. in kernel config files) must be removed. 2121 212220080408: 2123 psm(4) has gained write(2) support in native operation level. 2124 Arbitrary commands can be written to /dev/psm%d and status can 2125 be read back from it. Therefore, an application is responsible 2126 for status validation and error recovery. It is a no-op in 2127 other operation levels. 2128 212920080312: 2130 Support for KSE threading has been removed from the kernel. To 2131 run legacy applications linked against KSE libmap.conf may 2132 be used. The following libmap.conf may be used to ensure 2133 compatibility with any prior release: 2134 2135 libpthread.so.1 libthr.so.1 2136 libpthread.so.2 libthr.so.2 2137 libkse.so.3 libthr.so.3 2138 213920080301: 2140 The layout of struct vmspace has changed. This affects libkvm 2141 and any executables that link against libkvm and use the 2142 kvm_getprocs() function. In particular, but not exclusively, 2143 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2144 The effects are minimal, but it's advisable to upgrade world 2145 nonetheless. 2146 214720080229: 2148 The latest em driver no longer has support in it for the 2149 82575 adapter, this is now moved to the igb driver. The 2150 split was done to make new features that are incompatible 2151 with older hardware easier to do. 2152 215320080220: 2154 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2155 likewise the kernel option is now GEOM_LINUX_LVM. 2156 215720080211: 2158 The default NFS mount mode has changed from UDP to TCP for 2159 increased reliability. If you rely on (insecurely) NFS 2160 mounting across a firewall you may need to update your 2161 firewall rules. 2162 216320080208: 2164 Belatedly note the addition of m_collapse for compacting 2165 mbuf chains. 2166 216720080126: 2168 The fts(3) structures have been changed to use adequate 2169 integer types for their members and so to be able to cope 2170 with huge file trees. The old fts(3) ABI is preserved 2171 through symbol versioning in libc, so third-party binaries 2172 using fts(3) should still work, although they will not take 2173 advantage of the extended types. At the same time, some 2174 third-party software might fail to build after this change 2175 due to unportable assumptions made in its source code about 2176 fts(3) structure members. Such software should be fixed 2177 by its vendor or, in the worst case, in the ports tree. 2178 FreeBSD_version 800015 marks this change for the unlikely 2179 case that a portable fix is impossible. 2180 218120080123: 2182 To upgrade to -current after this date, you must be running 2183 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2184 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2185 218620071128: 2187 The ADAPTIVE_GIANT kernel option has been retired because its 2188 functionality is the default now. 2189 219020071118: 2191 The AT keyboard emulation of sunkbd(4) has been turned on 2192 by default. In order to make the special symbols of the Sun 2193 keyboards driven by sunkbd(4) work under X these now have 2194 to be configured the same way as Sun USB keyboards driven 2195 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2196 2197 Option "XkbLayout" "us" 2198 Option "XkbRules" "xorg" 2199 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2200 220120071024: 2202 It has been decided that it is desirable to provide ABI 2203 backwards compatibility to the FreeBSD 4/5/6 versions of the 2204 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2205 broken with the introduction of PCI domain support (see the 2206 20070930 entry). Unfortunately, this required the ABI of 2207 PCIOCGETCONF to be broken again in order to be able to 2208 provide backwards compatibility to the old version of that 2209 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2210 again. As for prominent ports this affects neither pciutils 2211 nor xorg-server this time, the hal port needs to be rebuilt 2212 however. 2213 221420071020: 2215 The misnamed kthread_create() and friends have been renamed 2216 to kproc_create() etc. Many of the callers already 2217 used kproc_start().. 2218 I will return kthread_create() and friends in a while 2219 with implementations that actually create threads, not procs. 2220 Renaming corresponds with version 800002. 2221 222220071010: 2223 RELENG_7 branched. 2224 2225COMMON ITEMS: 2226 2227 General Notes 2228 ------------- 2229 Avoid using make -j when upgrading. While generally safe, there are 2230 sometimes problems using -j to upgrade. If your upgrade fails with 2231 -j, please try again without -j. From time to time in the past there 2232 have been problems using -j with buildworld and/or installworld. This 2233 is especially true when upgrading between "distant" versions (eg one 2234 that cross a major release boundary or several minor releases, or when 2235 several months have passed on the -current branch). 2236 2237 Sometimes, obscure build problems are the result of environment 2238 poisoning. This can happen because the make utility reads its 2239 environment when searching for values for global variables. To run 2240 your build attempts in an "environmental clean room", prefix all make 2241 commands with 'env -i '. See the env(1) manual page for more details. 2242 2243 When upgrading from one major version to another it is generally best 2244 to upgrade to the latest code in the currently installed branch first, 2245 then do an upgrade to the new branch. This is the best-tested upgrade 2246 path, and has the highest probability of being successful. Please try 2247 this approach before reporting problems with a major version upgrade. 2248 2249 When upgrading a live system, having a root shell around before 2250 installing anything can help undo problems. Not having a root shell 2251 around can lead to problems if pam has changed too much from your 2252 starting point to allow continued authentication after the upgrade. 2253 2254 ZFS notes 2255 --------- 2256 When upgrading the boot ZFS pool to a new version, always follow 2257 these two steps: 2258 2259 1.) recompile and reinstall the ZFS boot loader and boot block 2260 (this is part of "make buildworld" and "make installworld") 2261 2262 2.) update the ZFS boot block on your boot drive 2263 2264 The following example updates the ZFS boot block on the first 2265 partition (freebsd-boot) of a GPT partitioned drive ad0: 2266 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2267 2268 Non-boot pools do not need these updates. 2269 2270 To build a kernel 2271 ----------------- 2272 If you are updating from a prior version of FreeBSD (even one just 2273 a few days old), you should follow this procedure. It is the most 2274 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2275 2276 make kernel-toolchain 2277 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2278 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2279 2280 To test a kernel once 2281 --------------------- 2282 If you just want to boot a kernel once (because you are not sure 2283 if it works, or if you want to boot a known bad kernel to provide 2284 debugging information) run 2285 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2286 nextboot -k testkernel 2287 2288 To just build a kernel when you know that it won't mess you up 2289 -------------------------------------------------------------- 2290 This assumes you are already running a CURRENT system. Replace 2291 ${arch} with the architecture of your machine (e.g. "i386", 2292 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2293 2294 cd src/sys/${arch}/conf 2295 config KERNEL_NAME_HERE 2296 cd ../compile/KERNEL_NAME_HERE 2297 make depend 2298 make 2299 make install 2300 2301 If this fails, go to the "To build a kernel" section. 2302 2303 To rebuild everything and install it on the current system. 2304 ----------------------------------------------------------- 2305 # Note: sometimes if you are running current you gotta do more than 2306 # is listed here if you are upgrading from a really old current. 2307 2308 <make sure you have good level 0 dumps> 2309 make buildworld 2310 make kernel KERNCONF=YOUR_KERNEL_HERE 2311 [1] 2312 <reboot in single user> [3] 2313 mergemaster -p [5] 2314 make installworld 2315 mergemaster -i [4] 2316 make delete-old [6] 2317 <reboot> 2318 2319 To cross-install current onto a separate partition 2320 -------------------------------------------------- 2321 # In this approach we use a separate partition to hold 2322 # current's root, 'usr', and 'var' directories. A partition 2323 # holding "/", "/usr" and "/var" should be about 2GB in 2324 # size. 2325 2326 <make sure you have good level 0 dumps> 2327 <boot into -stable> 2328 make buildworld 2329 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2330 <maybe newfs current's root partition> 2331 <mount current's root partition on directory ${CURRENT_ROOT}> 2332 make installworld DESTDIR=${CURRENT_ROOT} 2333 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2334 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2335 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2336 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2337 <reboot into current> 2338 <do a "native" rebuild/install as described in the previous section> 2339 <maybe install compatibility libraries from ports/misc/compat*> 2340 <reboot> 2341 2342 2343 To upgrade in-place from stable to current 2344 ---------------------------------------------- 2345 <make sure you have good level 0 dumps> 2346 make buildworld [9] 2347 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2348 [1] 2349 <reboot in single user> [3] 2350 mergemaster -p [5] 2351 make installworld 2352 mergemaster -i [4] 2353 make delete-old [6] 2354 <reboot> 2355 2356 Make sure that you've read the UPDATING file to understand the 2357 tweaks to various things you need. At this point in the life 2358 cycle of current, things change often and you are on your own 2359 to cope. The defaults can also change, so please read ALL of 2360 the UPDATING entries. 2361 2362 Also, if you are tracking -current, you must be subscribed to 2363 freebsd-current@freebsd.org. Make sure that before you update 2364 your sources that you have read and understood all the recent 2365 messages there. If in doubt, please track -stable which has 2366 much fewer pitfalls. 2367 2368 [1] If you have third party modules, such as vmware, you 2369 should disable them at this point so they don't crash your 2370 system on reboot. 2371 2372 [3] From the bootblocks, boot -s, and then do 2373 fsck -p 2374 mount -u / 2375 mount -a 2376 cd src 2377 adjkerntz -i # if CMOS is wall time 2378 Also, when doing a major release upgrade, it is required that 2379 you boot into single user mode to do the installworld. 2380 2381 [4] Note: This step is non-optional. Failure to do this step 2382 can result in a significant reduction in the functionality of the 2383 system. Attempting to do it by hand is not recommended and those 2384 that pursue this avenue should read this file carefully, as well 2385 as the archives of freebsd-current and freebsd-hackers mailing lists 2386 for potential gotchas. The -U option is also useful to consider. 2387 See mergemaster(8) for more information. 2388 2389 [5] Usually this step is a noop. However, from time to time 2390 you may need to do this if you get unknown user in the following 2391 step. It never hurts to do it all the time. You may need to 2392 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2393 install) after the buildworld before this step if you last updated 2394 from current before 20130425 or from -stable before 20130430. 2395 2396 [6] This only deletes old files and directories. Old libraries 2397 can be deleted by "make delete-old-libs", but you have to make 2398 sure that no program is using those libraries anymore. 2399 2400 [8] In order to have a kernel that can run the 4.x binaries needed to 2401 do an installworld, you must include the COMPAT_FREEBSD4 option in 2402 your kernel. Failure to do so may leave you with a system that is 2403 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2404 required to run the 5.x binaries on more recent kernels. And so on 2405 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2406 2407 Make sure that you merge any new devices from GENERIC since the 2408 last time you updated your kernel config file. 2409 2410 [9] When checking out sources, you must include the -P flag to have 2411 cvs prune empty directories. 2412 2413 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2414 "?=" instead of the "=" assignment operator, so that buildworld can 2415 override the CPUTYPE if it needs to. 2416 2417 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2418 not on the command line, or in /etc/make.conf. buildworld will 2419 warn if it is improperly defined. 2420FORMAT: 2421 2422This file contains a list, in reverse chronological order, of major 2423breakages in tracking -current. It is not guaranteed to be a complete 2424list of such breakages, and only contains entries since October 10, 2007. 2425If you need to see UPDATING entries from before that date, you will need 2426to fetch an UPDATING file from an older FreeBSD release. 2427 2428Copyright information: 2429 2430Copyright 1998-2009 M.
