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 1920161222 p45 FreeBSD-SA-16:39.ntp 20 21 Fix multiple vulnerabilities of ntp. 22 2320161208 p44 FreeBSD-SA-16:37.libc [revised] 24 25 Fix regressions introduced by SA-16:37.libc. 26 2720161206 p43 FreeBSD-SA-16:36.telnetd 28 FreeBSD-SA-16:37.libc 29 FreeBSD-SA-16:38.bhyve 30 FreeBSD-EN-16:19.tzcode 31 FreeBSD-EN-16:20.tzdata 32 33 Fix possible login(1) argument injection in telnetd(8).

New NTP version is 4.2.8p4. 168 169 The configuration file syntax has been changed, thus mergemaster 170 run is recommended. Now the "kod" parameter requires "limited" 171 parameter. If the ntp.conf is not updated, the ntpd will run 172 successfully, but with KoD disabled. 173 17420151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 175 Revised patch to address a regression that prevents NIS from working. 176 17720150929: p21 FreeBSD-SA-15:24.rpcbind 178 179 Fix rpcbind(8) remote denial of service.

[SA-15:01] 303 30420141223: p3 FreeBSD-SA-14:31.ntp 305 FreeBSD-EN-14:13.freebsd-update 306 307 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 308 Fix directory deletion issue in freebsd-update. [EN-14:13] 309 31020141217: p2 FreeBSD-SA-14:30.unbound 311 Fix unbound remote denial of service vulnerability. 312 31320141210: p1 FreeBSD-SA-14:27.stdio 314 FreeBSD-SA-14:28.file 315 316 Fix buffer overflow in stdio. [SA-14:27] 317 318 Fix multiple vulnerabilities in file(1) and libmagic(3). 319 [SA-14:28] 320 32120140904: 322 The ofwfb driver, used to provide a graphics console on PowerPC when 323 using vt(4), no longer allows mmap() of all of physical memory. This 324 will prevent Xorg on PowerPC with some ATI graphics cards from 325 initializing properly unless x11-servers/xorg-server is updated to 326 1.12.4_8 or newer. 327 32820140831: 329 The libatf-c and libatf-c++ major versions were downgraded to 0 and 330 1 respectively to match the upstream numbers. They were out of 331 sync because, when they were originally added to FreeBSD, the 332 upstream versions were not respected. These libraries are private 333 and not yet built by default, so renumbering them should be a 334 non-issue. However, unclean source trees will yield broken test 335 programs once the operator executes "make delete-old-libs" after a 336 "make installworld". 337 338 Additionally, the atf-sh binary was made private by moving it into 339 /usr/libexec/. Already-built shell test programs will keep the 340 path to the old binary so they will break after "make delete-old" 341 is run. 342 343 If you are using WITH_TESTS=yes (not the default), wipe the object 344 tree and rebuild from scratch to prevent spurious test failures. 345 This is only needed once: the misnumbered libraries and misplaced 346 binaries have been added to OptionalObsoleteFiles.inc so they will 347 be removed during a clean upgrade. 348 34920140814: 350 The ixgbe tunables now match their sysctl counterparts, for example: 351 hw.ixgbe.enable_aim => hw.ix.enable_aim 352 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 353 35420140801: 355 The NFSv4.1 server committed by r269398 changes the internal 356 function call interfaces used between the NFS and krpc modules. 357 As such, __FreeBSD_version was bumped. 358 35920140729: 360 The default unbound configuration has been modified to address 361 issues with reverse lookups on networks that use private 362 address ranges. If you use the local_unbound service, run 363 "service local_unbound setup" as root to regenerate your 364 configuration, then "service local_unbound reload" to load the 365 new configuration. 366 36720140717: 368 It is no longer necessary to include the dwarf version in your DEBUG 369 options in your kernel config file. The bug that required it to be 370 placed in the config file has bene fixed. DEBUG should now just 371 contain -g. The build system will automatically update things 372 to do the right thing. 373 37420140715: 375 Several ABI breaking changes were merged to CTL and new iSCSI code. 376 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 377 iscsictl need to be rebuilt to work with a new kernel. 378 37920140708: 380 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 381 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 382 which differs from the behaviour controlled by this knob.) 383 38420140608: 385 On i386 and amd64 systems, the onifconsole flag is now set by default 386 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 387 as a login TTY if it is set in the bootloader as an active kernel 388 console. No changes in behavior should result otherwise. To revert to 389 the previous behavior, set ttyu0 to "off" in /etc/ttys. 390 39120140512: 392 Clang and llvm have been upgraded to 3.4.1 release. 393 39420140321: 395 Clang and llvm have been upgraded to 3.4 release. 396 39720140306: 398 If a Makefile in a tests/ directory was auto-generating a Kyuafile 399 instead of providing an explicit one, this would prevent such 400 Makefile from providing its own Kyuafile in the future during 401 NO_CLEAN builds. This has been fixed in the Makefiles but manual 402 intervention is needed to clean an objdir if you use NO_CLEAN: 403 # find /usr/obj -name Kyuafile | xargs rm -f 404 40520140303: 406 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 407 capability mode support. Please note that enabling the feature in 408 kernel is still highly recommended. 409 41020140227: 411 OpenSSH is now built with sandbox support, and will use sandbox as 412 the default privilege separation method. This requires Capsicum 413 capability mode support in kernel. 414 41520140216: 416 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 417 been deprecated and will not be part of FreeBSD 11.0 and later 418 releases. If you use this driver, please consider switching to 419 the nfe(4) driver instead. 420 42120140120: 422 10.0-RELEASE. 423 42420131216: 425 The behavior of gss_pseudo_random() for the krb5 mechanism 426 has changed, for applications requesting a longer random string 427 than produced by the underlying enctype's pseudo-random() function. 428 In particular, the random string produced from a session key of 429 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 430 be different at the 17th octet and later, after this change. 431 The counter used in the PRF+ construction is now encoded as a 432 big-endian integer in accordance with RFC 4402. 433 __FreeBSD_version is bumped to 1000701. 434 43520131108: 436 The WITHOUT_ATF build knob has been removed and its functionality 437 has been subsumed into the more generic WITHOUT_TESTS. If you were 438 using the former to disable the build of the ATF libraries, you 439 should change your settings to use the latter. 440 44120131031: 442 The default version of mtree is nmtree which is obtained from 443 NetBSD. The output is generally the same, but may vary 444 slightly. If you found you need identical output adding 445 "-F freebsd9" to the command line should do the trick. For the 446 time being, the old mtree is available as fmtree. 447 44820131014: 449 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 450 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 451 1.1.4_8 and verify bsdyml not linked in, before running "make 452 delete-old-libs": 453 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 454 or 455 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 456 45720131010: 458 The rc.d/jail script has been updated to support jail(8) 459 configuration file. The "jail_<jname>_*" rc.conf(5) variables 460 for per-jail configuration are automatically converted to 461 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 462 This is transparently backward compatible. See below about some 463 incompatibilities and rc.conf(5) manual page for more details. 464 465 These variables are now deprecated in favor of jail(8) configuration 466 file. One can use "rc.d/jail config <jname>" command to generate 467 a jail(8) configuration file in /var/run/jail.<jname>.conf without 468 running the jail(8) utility. The default pathname of the 469 configuration file is /etc/jail.conf and can be specified by 470 using $jail_conf or $jail_<jname>_conf variables. 471 472 Please note that jail_devfs_ruleset accepts an integer at 473 this moment. Please consider to rewrite the ruleset name 474 with an integer. 475 47620130930: 477 BIND has been removed from the base system. If all you need 478 is a local resolver, simply enable and start the local_unbound 479 service instead. Otherwise, several versions of BIND are 480 available in the ports tree. The dns/bind99 port is one example. 481 482 With this change, nslookup(1) and dig(1) are no longer in the base 483 system. Users should instead use host(1) and drill(1) which are 484 in the base system. Alternatively, nslookup and dig can 485 be obtained by installing the dns/bind-tools port. 486 48720130916: 488 With the addition of unbound(8), a new unbound user is now 489 required during installworld. "mergemaster -p" can be used to 490 add the user prior to installworld, as documented in the handbook. 491 49220130911: 493 OpenSSH is now built with DNSSEC support, and will by default 494 silently trust signed SSHFP records. This can be controlled with 495 the VerifyHostKeyDNS client configuration setting. DNSSEC support 496 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 497 49820130906: 499 The GNU Compiler Collection and C++ standard library (libstdc++) 500 are no longer built by default on platforms where clang is the system 501 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 502 options in src.conf. 503 50420130905: 505 The PROCDESC kernel option is now part of the GENERIC kernel 506 configuration and is required for the rwhod(8) to work. 507 If you are using custom kernel configuration, you should include 508 'options PROCDESC'. 509 51020130905: 511 The API and ABI related to the Capsicum framework was modified 512 in backward incompatible way. The userland libraries and programs 513 have to be recompiled to work with the new kernel. This includes the 514 following libraries and programs, but the whole buildworld is 515 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 516 kdump, procstat, rwho, rwhod, uniq. 517 51820130903: 519 AES-NI intrinsic support has been added to gcc. The AES-NI module 520 has been updated to use this support. A new gcc is required to build 521 the aesni module on both i386 and amd64. 522 52320130821: 524 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 525 Thus "device padlock_rng" and "device rdrand_rng" should be 526 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 527 52820130813: 529 WITH_ICONV has been split into two feature sets. WITH_ICONV now 530 enables just the iconv* functionality and is now on by default. 531 WITH_LIBICONV_COMPAT enables the libiconv api and link time 532 compatability. Set WITHOUT_ICONV to build the old way. 533 If you have been using WITH_ICONV before, you will very likely 534 need to turn on WITH_LIBICONV_COMPAT. 535 53620130806: 537 INVARIANTS option now enables DEBUG for code with OpenSolaris and 538 Illumos origin, including ZFS. If you have INVARIANTS in your 539 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 540 explicitly. 541 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 542 locks if WITNESS option was set. Because that generated a lot of 543 witness(9) reports and all of them were believed to be false 544 positives, this is no longer done. New option OPENSOLARIS_WITNESS 545 can be used to achieve the previous behavior. 546 54720130806: 548 Timer values in IPv6 data structures now use time_uptime instead 549 of time_second. Although this is not a user-visible functional 550 change, userland utilities which directly use them---ndp(8), 551 rtadvd(8), and rtsold(8) in the base system---need to be updated 552 to r253970 or later. 553 55420130802: 555 find -delete can now delete the pathnames given as arguments, 556 instead of only files found below them or if the pathname did 557 not contain any slashes. Formerly, the following error message 558 would result: 559 560 find: -delete: <path>: relative path potentially not safe 561 562 Deleting the pathnames given as arguments can be prevented 563 without error messages using -mindepth 1 or by changing 564 directory and passing "." as argument to find. This works in the 565 old as well as the new version of find. 566 56720130726: 568 Behavior of devfs rules path matching has been changed. 569 Pattern is now always matched against fully qualified devfs 570 path and slash characters must be explicitly matched by 571 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 572 subdirectories must be reviewed. 573 57420130716: 575 The default ARM ABI has changed to the ARM EABI. The old ABI is 576 incompatible with the ARM EABI and all programs and modules will 577 need to be rebuilt to work with a new kernel. 578 579 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 580 581 NOTE: Support for the old ABI will be removed in the future and 582 users are advised to upgrade. 583 58420130709: 585 pkg_install has been disconnected from the build if you really need it 586 you should add WITH_PKGTOOLS in your src.conf(5). 587 58820130709: 589 Most of network statistics structures were changed to be able 590 keep 64-bits counters. Thus all tools, that work with networking 591 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 592 59320130629: 594 Fix targets that run multiple make's to use && rather than ; 595 so that subsequent steps depend on success of previous. 596 597 NOTE: if building 'universe' with -j* on stable/8 or stable/9 598 it would be better to start the build using bmake, to avoid 599 overloading the machine. 600 60120130618: 602 Fix a bug that allowed a tracing process (e.g. gdb) to write 603 to a memory-mapped file in the traced process's address space 604 even if neither the traced process nor the tracing process had 605 write access to that file. 606 60720130615: 608 CVS has been removed from the base system. An exact copy 609 of the code is available from the devel/cvs port. 610 61120130613: 612 Some people report the following error after the switch to bmake: 613 614 make: illegal option -- J 615 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 616 ... 617 *** [buildworld] Error code 2 618 619 this likely due to an old instance of make in 620 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 621 which src/Makefile will use that blindly, if it exists, so if 622 you see the above error: 623 624 rm -rf `make -V MAKEPATH` 625 626 should resolve it. 627 62820130516: 629 Use bmake by default. 630 Whereas before one could choose to build with bmake via 631 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 632 make. The goal is to remove these knobs for 10-RELEASE. 633 634 It is worth noting that bmake (like gmake) treats the command 635 line as the unit of failure, rather than statements within the 636 command line. Thus '(cd some/where && dosomething)' is safer 637 than 'cd some/where; dosomething'. The '()' allows consistent 638 behavior in parallel build. 639 64020130429: 641 Fix a bug that allows NFS clients to issue READDIR on files. 642 64320130426: 644 The WITHOUT_IDEA option has been removed because 645 the IDEA patent expired. 646 64720130426: 648 The sysctl which controls TRIM support under ZFS has been renamed 649 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 650 enabled by default. 651 65220130425: 653 The mergemaster command now uses the default MAKEOBJDIRPREFIX 654 rather than creating it's own in the temporary directory in 655 order allow access to bootstrapped versions of tools such as 656 install and mtree. When upgrading from version of FreeBSD where 657 the install command does not support -l, you will need to 658 install a new mergemaster command if mergemaster -p is required. 659 This can be accomplished with the command (cd src/usr.sbin/mergemaster 660 && make install). 661 66220130404: 663 Legacy ATA stack, disabled and replaced by new CAM-based one since 664 FreeBSD 9.0, completely removed from the sources. Kernel modules 665 atadisk and atapi*, user-level tools atacontrol and burncd are 666 removed. Kernel option `options ATA_CAM` is now permanently enabled 667 and removed. 668 66920130319: 670 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 671 and socketpair(2). Software, in particular Kerberos, may 672 automatically detect and use these during building. The resulting 673 binaries will not work on older kernels. 674 67520130308: 676 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 677 information, see the respective 20130304 entry). 678 67920130304: 680 Recent commits to callout(9) changed the size of struct callout, 681 so the KBI is probably heavily disturbed. Also, some functions 682 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 683 by macros. Every kernel module using it won't load, so rebuild 684 is requested. 685 686 The ctl device has been re-enabled in GENERIC for i386 and amd64, 687 but does not initialize by default (because of the new CTL_DISABLE 688 option) to save memory. To re-enable it, remove the CTL_DISABLE 689 option from the kernel config file or set kern.cam.ctl.disable=0 690 in /boot/loader.conf. 691 69220130301: 693 The ctl device has been disabled in GENERIC for i386 and amd64. 694 This was done due to the extra memory being allocated at system 695 initialisation time by the ctl driver which was only used if 696 a CAM target device was created. This makes a FreeBSD system 697 unusable on 128MB or less of RAM. 698 69920130208: 700 A new compression method (lz4) has been merged to -HEAD. Please 701 refer to zpool-features(7) for more information. 702 703 Please refer to the "ZFS notes" section of this file for information 704 on upgrading boot ZFS pools. 705 70620130129: 707 A BSD-licensed patch(1) variant has been added and is installed 708 as bsdpatch, being the GNU version the default patch. 709 To inverse the logic and use the BSD-licensed one as default, 710 while having the GNU version installed as gnupatch, rebuild 711 and install world with the WITH_BSD_PATCH knob set. 712 71320130121: 714 Due to the use of the new -l option to install(1) during build 715 and install, you must take care not to directly set the INSTALL 716 make variable in your /etc/make.conf, /etc/src.conf, or on the 717 command line. If you wish to use the -C flag for all installs 718 you may be able to add INSTALL+=-C to /etc/make.conf or 719 /etc/src.conf. 720 72120130118: 722 The install(1) option -M has changed meaning and now takes an 723 argument that is a file or path to append logs to. In the 724 unlikely event that -M was the last option on the command line 725 and the command line contained at least two files and a target 726 directory the first file will have logs appended to it. The -M 727 option served little practical purpose in the last decade so its 728 use is expected to be extremely rare. 729 73020121223: 731 After switching to Clang as the default compiler some users of ZFS 732 on i386 systems started to experience stack overflow kernel panics. 733 Please consider using 'options KSTACK_PAGES=4' in such configurations. 734 73520121222: 736 GEOM_LABEL now mangles label names read from file system metadata. 737 Mangling affect labels containing spaces, non-printable characters, 738 '%' or '"'. Device names in /etc/fstab and other places may need to 739 be updated. 740 74120121217: 742 By default, only the 10 most recent kernel dumps will be saved. To 743 restore the previous behaviour (no limit on the number of kernel dumps 744 stored in the dump directory) add the following line to /etc/rc.conf: 745 746 savecore_flags="" 747 74820121201: 749 With the addition of auditdistd(8), a new auditdistd user is now 750 required during installworld. "mergemaster -p" can be used to 751 add the user prior to installworld, as documented in the handbook. 752 75320121117: 754 The sin6_scope_id member variable in struct sockaddr_in6 is now 755 filled by the kernel before passing the structure to the userland via 756 sysctl or routing socket. This means the KAME-specific embedded scope 757 id in sin6_addr.s6_addr[2] is always cleared in userland application. 758 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 759 __FreeBSD_version is bumped to 1000025. 760 76120121105: 762 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 763 This means that the world and kernel will be compiled with clang 764 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 765 and /usr/bin/cpp. To disable this behavior and revert to building 766 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 767 of current may need to bootstrap WITHOUT_CLANG first if the clang 768 build fails (its compatibility window doesn't extend to the 9 stable 769 branch point). 770 77120121102: 772 The IPFIREWALL_FORWARD kernel option has been removed. Its 773 functionality now turned on by default. 774 77520121023: 776 The ZERO_COPY_SOCKET kernel option has been removed and 777 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 778 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 779 mechanism which is not safe and may result in kernel crashes. 780 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 781 driver supports disposeable external page sized mbuf storage. 782 Proper replacements for both zero-copy mechanisms are under 783 consideration and will eventually lead to complete removal 784 of the two kernel options. 785 78620121023: 787 The IPv4 network stack has been converted to network byte 788 order. The following modules need to be recompiled together 789 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 790 pf(4), ipfw(4), ng_ipfw(4), stf(4). 791 79220121022: 793 Support for non-MPSAFE filesystems was removed from VFS. The 794 VFS_VERSION was bumped, all filesystem modules shall be 795 recompiled. 796 79720121018: 798 All the non-MPSAFE filesystems have been disconnected from 799 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 800 portalfs, smbfs, xfs. 801 80220121016: 803 The interface cloning API and ABI has changed. The following 804 modules need to be recompiled together with kernel: 805 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 806 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 807 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 808 80920121015: 810 The sdhci driver was split in two parts: sdhci (generic SD Host 811 Controller logic) and sdhci_pci (actual hardware driver). 812 No kernel config modifications are required, but if you 813 load sdhc as a module you must switch to sdhci_pci instead. 814 81520121014: 816 Import the FUSE kernel and userland support into base system. 817 81820121013: 819 The GNU sort(1) program has been removed since the BSD-licensed 820 sort(1) has been the default for quite some time and no serious 821 problems have been reported. The corresponding WITH_GNU_SORT 822 knob has also gone. 823 82420121006: 825 The pfil(9) API/ABI for AF_INET family has been changed. Packet 826 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 827 with new kernel. 828 82920121001: 830 The net80211(4) ABI has been changed to allow for improved driver 831 PS-POLL and power-save support. All wireless drivers need to be 832 recompiled to work with the new kernel. 833 83420120913: 835 The random(4) support for the VIA hardware random number 836 generator (`PADLOCK') is no longer enabled unconditionally. 837 Add the padlock_rng device in the custom kernel config if 838 needed. The GENERIC kernels on i386 and amd64 do include the 839 device, so the change only affects the custom kernel 840 configurations. 841 84220120908: 843 The pf(4) packet filter ABI has been changed. pfctl(8) and 844 snmp_pf module need to be recompiled to work with new kernel. 845 84620120828: 847 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 848 to -HEAD. Pools that have empty_bpobj in active state can not be 849 imported read-write with ZFS implementations that do not support 850 this feature. For more information read the zpool-features(5) 851 manual page. 852 85320120727: 854 The sparc64 ZFS loader has been changed to no longer try to auto- 855 detect ZFS providers based on diskN aliases but now requires these 856 to be explicitly listed in the OFW boot-device environment variable. 857 85820120712: 859 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 860 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 861 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 862 86320120712: 864 The following sysctls and tunables have been renamed for consistency 865 with other variables: 866 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 867 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 868 86920120628: 870 The sort utility has been replaced with BSD sort. For now, GNU sort 871 is also available as "gnusort" or the default can be set back to 872 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 873 installed as "bsdsort". 874 87520120611: 876 A new version of ZFS (pool version 5000) has been merged to -HEAD. 877 Starting with this version the old system of ZFS pool versioning 878 is superseded by "feature flags". This concept enables forward 879 compatibility against certain future changes in functionality of ZFS 880 pools. The first read-only compatible "feature flag" for ZFS pools 881 is named "com.delphix:async_destroy". For more information 882 read the new zpool-features(5) manual page. 883 Please refer to the "ZFS notes" section of this file for information 884 on upgrading boot ZFS pools. 885 88620120417: 887 The malloc(3) implementation embedded in libc now uses sources imported 888 as contrib/jemalloc. The most disruptive API change is to 889 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 890 delete it prior to installworld, and optionally re-create it using the 891 new format after rebooting. See malloc.conf(5) for details 892 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 893 NAMESPACE section). 894 89520120328: 896 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 897 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 898 now spelled mips. This is to aid compatibility with third-party 899 software that expects this naming scheme in uname(3). Little-endian 900 settings are unchanged. If you are updating a big-endian mips64 machine 901 from before this change, you may need to set MACHINE_ARCH=mips64 in 902 your environment before the new build system will recognize your machine. 903 90420120306: 905 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 906 platforms. 907 90820120229: 909 Now unix domain sockets behave "as expected" on nullfs(5). Previously 910 nullfs(5) did not pass through all behaviours to the underlying layer, 911 as a result if we bound to a socket on the lower layer we could connect 912 only to the lower path; if we bound to the upper layer we could connect 913 only to the upper path. The new behavior is one can connect to both the 914 lower and the upper paths regardless what layer path one binds to. 915 91620120211: 917 The getifaddrs upgrade path broken with 20111215 has been restored. 918 If you have upgraded in between 20111215 and 20120209 you need to 919 recompile libc again with your kernel. You still need to recompile 920 world to be able to configure CARP but this restriction already 921 comes from 20111215. 922 92320120114: 924 The set_rcvar() function has been removed from /etc/rc.subr. All 925 base and ports rc.d scripts have been updated, so if you have a 926 port installed with a script in /usr/local/etc/rc.d you can either 927 hand-edit the rcvar= line, or reinstall the port. 928 929 An easy way to handle the mass-update of /etc/rc.d: 930 rm /etc/rc.d/* && mergemaster -i 931 93220120109: 933 panic(9) now stops other CPUs in the SMP systems, disables interrupts 934 on the current CPU and prevents other threads from running. 935 This behavior can be reverted using the kern.stop_scheduler_on_panic 936 tunable/sysctl. 937 The new behavior can be incompatible with kern.sync_on_panic. 938 93920111215: 940 The carp(4) facility has been changed significantly. Configuration 941 of the CARP protocol via ifconfig(8) has changed, as well as format 942 of CARP events submitted to devd(8) has changed. See manual pages 943 for more information. The arpbalance feature of carp(4) is currently 944 not supported anymore. 945 946 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 947 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 948 need to be recompiled. 949 95020111122: 951 The acpi_wmi(4) status device /dev/wmistat has been renamed to 952 /dev/wmistat0. 953 95420111108: 955 The option VFS_ALLOW_NONMPSAFE option has been added in order to 956 explicitely support non-MPSAFE filesystems. 957 It is on by default for all supported platform at this present 958 time. 959 96020111101: 961 The broken amd(4) driver has been replaced with esp(4) in the amd64, 962 i386 and pc98 GENERIC kernel configuration files. 963 96420110930: 965 sysinstall has been removed 966 96720110923: 968 The stable/9 branch created in subversion. This corresponds to the 969 RELENG_9 branch in CVS. 970 97120110913: 972 This commit modifies vfs_register() so that it uses a hash 973 calculation to set vfc_typenum, which is enabled by default. 974 The first time a system is booted after this change, the 975 vfc_typenum values will change for all file systems. The 976 main effect of this is a change to the NFS server file handles 977 for file systems that use vfc_typenum in their fsid, such as ZFS. 978 It will, however, prevent vfc_typenum from changing when file 979 systems are loaded in a different order for subsequent reboots. 980 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 981 until you are ready to remount all NFS clients after a reboot. 982 98320110828: 984 Bump the shared library version numbers for libraries that 985 do not use symbol versioning, have changed the ABI compared 986 to stable/8 and which shared library version was not bumped. 987 Done as part of 9.0-RELEASE cycle. 988 98920110815: 990 During the merge of Capsicum features, the fget(9) KPI was modified. 991 This may require the rebuilding of out-of-tree device drivers -- 992 issues have been reported specifically with the nVidia device driver. 993 __FreeBSD_version is bumped to 900041. 994 995 Also, there is a period between 20110811 and 20110814 where the 996 special devices /dev/{stdin,stdout,stderr} did not work correctly. 997 Building world from a kernel during that window may not work. 998 99920110628: 1000 The packet filter (pf) code has been updated to OpenBSD 4.5. 1001 You need to update userland tools to be in sync with kernel. 1002 This update breaks backward compatibility with earlier pfsync(4) 1003 versions. Care must be taken when updating redundant firewall setups. 1004 100520110608: 1006 The following sysctls and tunables are retired on x86 platforms: 1007 machdep.hlt_cpus 1008 machdep.hlt_logical_cpus 1009 The following sysctl is retired: 1010 machdep.hyperthreading_allowed 1011 The sysctls were supposed to provide a way to dynamically offline and 1012 online selected CPUs on x86 platforms, but the implementation has not 1013 been reliable especially with SCHED_ULE scheduler. 1014 machdep.hyperthreading_allowed tunable is still available to ignore 1015 hyperthreading CPUs at OS level. 1016 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 1017 where X is an APIC ID of a CPU. Be advised, though, that disabling 1018 CPUs in non-uniform fashion will result in non-uniform topology and 1019 may lead to sub-optimal system performance with SCHED_ULE, which is 1020 a default scheduler. 1021 102220110607: 1023 cpumask_t type is retired and cpuset_t is used in order to describe 1024 a mask of CPUs. 1025 102620110531: 1027 Changes to ifconfig(8) for dynamic address family detection mandate 1028 that you are running a kernel of 20110525 or later. Make sure to 1029 follow the update procedure to boot a new kernel before installing 1030 world. 1031 103220110513: 1033 Support for sun4v architecture is officially dropped 1034 103520110503: 1036 Several KPI breaking changes have been committed to the mii(4) layer, 1037 the PHY drivers and consequently some Ethernet drivers using mii(4). 1038 This means that miibus.ko and the modules of the affected Ethernet 1039 drivers need to be recompiled. 1040 1041 Note to kernel developers: Given that the OUI bit reversion problem 1042 was fixed as part of these changes all mii(4) commits related to OUIs, 1043 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1044 handling, no longer can be merged verbatim to stable/8 and previous 1045 branches. 1046 104720110430: 1048 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1049 into their kernel configurations along with 'device pci'. 1050 105120110427: 1052 The default NFS client is now the new NFS client, so fstype "newnfs" 1053 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1054 Although mounts via fstype "nfs" will usually work without userland 1055 changes, it is recommended that the mount(8) and mount_nfs(8) 1056 commands be rebuilt from sources and that a link to mount_nfs called 1057 mount_oldnfs be created. The new client is compiled into the 1058 kernel with "options NFSCL" and this is needed for diskless root 1059 file systems. The GENERIC kernel configs have been changed to use 1060 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1061 To use the regular/old client, you can "mount -t oldnfs ...". For 1062 a diskless root file system, you must also include a line like: 1063 1064 vfs.root.mountfrom="oldnfs:" 1065 1066 in the boot/loader.conf on the root fs on the NFS server to make 1067 a diskless root fs use the old client. 1068 106920110424: 1070 The GENERIC kernels for all architectures now default to the new 1071 CAM-based ATA stack. It means that all legacy ATA drivers were 1072 removed and replaced by respective CAM drivers. If you are using 1073 ATA device names in /etc/fstab or other places, make sure to update 1074 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1075 where 'Y's are the sequential numbers starting from zero for each type 1076 in order of detection, unless configured otherwise with tunables, 1077 see cam(4)). There will be symbolic links created in /dev/ to map 1078 old adX devices to the respective adaY. They should provide basic 1079 compatibility for file systems mounting in most cases, but they do 1080 not support old user-level APIs and do not have respective providers 1081 in GEOM. Consider using updated management tools with new device names. 1082 1083 It is possible to load devices ahci, ata, siis and mvs as modules, 1084 but option ATA_CAM should remain in kernel configuration to make ata 1085 module work as CAM driver supporting legacy ATA controllers. Device ata 1086 still can be used in modular fashion (atacore + ...). Modules atadisk 1087 and atapi* are not used and won't affect operation in ATA_CAM mode. 1088 Note that to use CAM-based ATA kernel should include CAM devices 1089 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1090 them are parts of the cam module. 1091 1092 ataraid(4) functionality is now supported by the RAID GEOM class. 1093 To use it you can load geom_raid kernel module and use graid(8) tool 1094 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1095 1096 No kernel config options or code have been removed, so if a problem 1097 arises, please report it and optionally revert to the old ATA stack. 1098 In order to do it you can remove from the kernel config: 1099 options ATA_CAM 1100 device ahci 1101 device mvs 1102 device siis 1103 , and instead add back: 1104 device atadisk # ATA disk drives 1105 device ataraid # ATA RAID drives 1106 device atapicd # ATAPI CDROM drives 1107 device atapifd # ATAPI floppy drives 1108 device atapist # ATAPI tape drives 1109 111020110423: 1111 The default NFS server has been changed to the new server, which 1112 was referred to as the experimental server. If you need to switch 1113 back to the old NFS server, you must now put the "-o" option on 1114 both the mountd and nfsd commands. This can be done using the 1115 mountd_flags and nfs_server_flags rc.conf variables until an 1116 update to the rc scripts is committed, which is coming soon. 1117 111820110418: 1119 The GNU Objective-C runtime library (libobjc), and other Objective-C 1120 related components have been removed from the base system. If you 1121 require an Objective-C library, please use one of the available ports. 1122 112320110331: 1124 ath(4) has been split into bus- and device- modules. if_ath contains 1125 the HAL, the TX rate control and the network device code. if_ath_pci 1126 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1127 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1128 in order to use ath on everything else. 1129 1130 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1131 need to load if_ath and if_ath_pci for ath(4) operation. 1132 113320110314: 1134 As part of the replacement of sysinstall, the process of building 1135 release media has changed significantly. For details, please re-read 1136 release(7), which has been updated to reflect the new build process. 1137 113820110218: 1139 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1140 is the last available version under GPLv2. It brings a number of new 1141 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1142 4.1 and SSE 4.2), better support for powerpc64, a number of new 1143 directives, and lots of other small improvements. See the ChangeLog 1144 file in contrib/binutils for the full details. 1145 114620110218: 1147 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1148 compliant, and will now use half of hash for authentication. 1149 This will break interoperability with all stacks (including all 1150 actual FreeBSD versions) who implement 1151 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1152 authentication). 1153 The only workaround with such peers is to use another HMAC 1154 algorithm for IPsec ("phase 2") authentication. 1155 115620110207: 1157 Remove the uio_yield prototype and symbol. This function has 1158 been misnamed since it was introduced and should not be 1159 globally exposed with this name. The equivalent functionality 1160 is now available using kern_yield(curthread->td_user_pri). 1161 The function remains undocumented. 1162 116320110112: 1164 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1165 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1166 for scalar sysctls is defined but disabled. Code that needs 1167 UQUAD to pass the type checking that must compile on older 1168 systems where the define is not present can check against 1169 __FreeBSD_version >= 900030. 1170 1171 The system dialog(1) has been replaced with a new version previously 1172 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1173 with the previous version, but the libdialog associated with it has 1174 a largely incompatible API. As such, the original version of libdialog 1175 will be kept temporarily as libodialog, until its base system consumers 1176 are replaced or updated. Bump __FreeBSD_version to 900030. 1177 117820110103: 1179 If you are trying to run make universe on a -stable system, and you get 1180 the following warning: 1181 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1182 unknown. config(8) likely too old." 1183 or something similar to it, then you must upgrade your -stable system 1184 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1185 stable/8) or build the config from the latest stable/8 branch and 1186 install it on your system. 1187 1188 Prior to this date, building a current universe on 8-stable system from 1189 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1190 error in the first kernel build phase. A new config on those old 1191 systems will fix that problem for older versions of -current. 1192 119320101228: 1194 The TCP stack has been modified to allow Khelp modules to interact with 1195 it via helper hook points and store per-connection data in the TCP 1196 control block. Bump __FreeBSD_version to 900029. User space tools that 1197 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1198 be recompiled. 1199 120020101114: 1201 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1202 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1203 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1204 to take advantage of it instead of using custom implementations. This 1205 means that these drivers now no longer unconditionally advertise 1206 support for flow control but only do so if flow control is a selected 1207 media option. This was implemented in the generic support that way in 1208 order to allow flow control to be switched on and off via ifconfig(8) 1209 with the PHY specific default to typically off in order to protect 1210 from unwanted effects. Consequently, if you used flow control with 1211 one of the above mentioned drivers you now need to explicitly enable 1212 it, for example via: 1213 ifconfig bge0 media auto mediaopt flowcontrol 1214 1215 Along with the above mentioned changes generic support for setting 1216 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1217 e1000phy(4) as well as ip1000phy(4) have been converted to take 1218 advantage of it. This means that these drivers now no longer take the 1219 link0 parameter for selecting master mode but the master media option 1220 has to be used instead, for example like in the following: 1221 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1222 1223 Selection of master mode now is also available with all other PHY 1224 drivers supporting 1000baseT. 1225 122620101111: 1227 The TCP stack has received a significant update to add support for 1228 modularised congestion control and generally improve the clarity of 1229 congestion control decisions. Bump __FreeBSD_version to 900025. User 1230 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1231 sockstat) need to be recompiled. 1232 123320101002: 1234 The man(1) utility has been replaced by a new version that no longer 1235 uses /etc/manpath.config. Please consult man.conf(5) for how to 1236 migrate local entries to the new format. 1237 123820100928: 1239 The copyright strings printed by login(1) and sshd(8) at the time of a 1240 new connection have been removed to follow other operating systems and 1241 upstream sshd. 1242 124320100915: 1244 A workaround for a fixed ld bug has been removed in kernel code, 1245 so make sure that your system ld is built from sources after 1246 revision 210245 from 2010-07-19 (r211583 if building head kernel 1247 on stable/8, r211584 for stable/7; both from 2010-08-21). 1248 A symptom of incorrect ld version is different addresses for 1249 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1250 125120100913: 1252 The $ipv6_prefer variable in rc.conf(5) has been split into 1253 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1254 1255 The $ip6addrctl_policy is a variable to choose a pre-defined 1256 address selection policy set by ip6addrctl(8). A value 1257 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1258 default is "AUTO". 1259 1260 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1261 flag (see an entry of 20090926) is set on an interface with no 1262 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1263 security reason. If you want IPv6 link-local address on all 1264 interfaces by default, set this to "YES". 1265 1266 The old ipv6_prefer="YES" is equivalent to 1267 ipv6_activate_all_interfaces="YES" and 1268 ip6addrctl_policy="ipv6_prefer". 1269 127020100913: 1271 DTrace has grown support for userland tracing. Due to this, DTrace is 1272 now i386 and amd64 only. 1273 dtruss(1) is now installed by default on those systems and a new 1274 kernel module is needed for userland tracing: fasttrap. 1275 No changes to your kernel config file are necessary to enable 1276 userland tracing, but you might consider adding 'STRIP=' and 1277 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1278 to have informative userland stack traces in DTrace (ustack). 1279 128020100725: 1281 The acpi_aiboost(4) driver has been removed in favor of the new 1282 aibs(4) driver. You should update your kernel configuration file. 1283 128420100722: 1285 BSD grep has been imported to the base system and it is built by 1286 default. It is completely BSD licensed, highly GNU-compatible, uses 1287 less memory than its GNU counterpart and has a small codebase. 1288 However, it is slower than its GNU counterpart, which is mostly 1289 noticeable for larger searches, for smaller ones it is measurable 1290 but not significant. The reason is complex, the most important factor 1291 is that we lack a modern and efficient regex library and GNU 1292 overcomes this by optimizing the searches internally. Future work 1293 on improving the regex performance is planned, for the meantime, 1294 users that need better performance, can build GNU grep instead by 1295 setting the WITH_GNU_GREP knob. 1296 129720100713: 1298 Due to the import of powerpc64 support, all existing powerpc kernel 1299 configuration files must be updated with a machine directive like this: 1300 machine powerpc powerpc 1301 1302 In addition, an updated config(8) is required to build powerpc kernels 1303 after this change. 1304 130520100713: 1306 A new version of ZFS (version 15) has been merged to -HEAD. 1307 This version uses a python library for the following subcommands: 1308 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1309 For full functionality of these commands the following port must 1310 be installed: sysutils/py-zfs 1311 131220100429: 1313 'vm_page's are now hashed by physical address to an array of mutexes. 1314 Currently this is only used to serialize access to hold_count. Over 1315 time the page queue mutex will be peeled away. This changes the size 1316 of pmap on every architecture. And requires all callers of vm_page_hold 1317 and vm_page_unhold to be updated. 1318 131920100402: 1320 WITH_CTF can now be specified in src.conf (not recommended, there 1321 are some problems with static executables), make.conf (would also 1322 affect ports which do not use GNU make and do not override the 1323 compile targets) or in the kernel config (via "makeoptions 1324 WITH_CTF=yes"). 1325 When WITH_CTF was specified there before this was silently ignored, 1326 so make sure that WITH_CTF is not used in places which could lead 1327 to unwanted behavior. 1328 132920100311: 1330 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1331 to allow 32-bit compatibility on non-x86 platforms. All kernel 1332 configurations on amd64 and ia64 platforms using these options must 1333 be modified accordingly. 1334 133520100113: 1336 The utmp user accounting database has been replaced with utmpx, 1337 the user accounting interface standardized by POSIX. 1338 Unfortunately the semantics of utmp and utmpx don't match, 1339 making it practically impossible to support both interfaces. 1340 The user accounting database is used by tools like finger(1), 1341 last(1), talk(1), w(1) and ac(8). 1342 1343 All applications in the base system use utmpx. This means only 1344 local binaries (e.g. from the ports tree) may still use these 1345 utmp database files. These applications must be rebuilt to make 1346 use of utmpx. 1347 1348 After the system has been upgraded, it is safe to remove the old 1349 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1350 assuming their contents is of no importance anymore. Old wtmp 1351 databases can only be used by last(1) and ac(8) after they have 1352 been converted to the new format using wtmpcvt(1). 1353 135420100108: 1355 Introduce the kernel thread "deadlock resolver" (which can be enabled 1356 via the DEADLKRES option, see NOTES for more details) and the 1357 sleepq_type() function for sleepqueues. 1358 135920091202: 1360 The rc.firewall and rc.firewall6 were unified, and 1361 rc.firewall6 and rc.d/ip6fw were removed. 1362 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1363 variables are obsoleted. Instead, the following new rc 1364 variables are added to rc.d/ipfw: 1365 1366 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1367 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1368 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1369 1370 The meanings correspond to the relevant IPv4 variables. 1371 137220091125: 1373 8.0-RELEASE. 1374 137520091113: 1376 The default terminal emulation for syscons(4) has been changed 1377 from cons25 to xterm on all platforms except pc98. This means 1378 that the /etc/ttys file needs to be updated to ensure correct 1379 operation of applications on the console. 1380 1381 The terminal emulation style can be toggled per window by using 1382 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1383 options can be used to change the compile-time default back to 1384 cons25. 1385 1386 To prevent graphical artifacts, make sure the TERM environment 1387 variable is set to match the terminal emulation that is being 1388 performed by syscons(4). 1389 139020091109: 1391 The layout of the structure ieee80211req_scan_result has changed. 1392 Applications that require wireless scan results (e.g. ifconfig(8)) 1393 from net80211 need to be recompiled. 1394 1395 Applications such as wpa_supplicant(8) may require a full world 1396 build without using NO_CLEAN in order to get synchronized with the 1397 new structure. 1398 139920091025: 1400 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1401 There's one kernel module for each firmware. Adding "device iwnfw" 1402 to the kernel configuration file means including all three firmware 1403 images inside the kernel. If you want to include just the one for 1404 your wireless card, use the devices iwn4965fw, iwn5000fw or 1405 iwn5150fw. 1406 140720090926: 1408 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1409 into rc.d/netif. The changes are the following: 1410 1411 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1412 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1413 Note that both variables need the "inet6" keyword at the head. 1414 1415 Do not set $ipv6_network_interfaces manually if you do not 1416 understand what you are doing. It is not needed in most cases. 1417 1418 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1419 they are obsolete. 1420 1421 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1422 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1423 1424 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1425 all configured interfaces have "inet6 accept_rtadv" in the 1426 $ifconfig_IF_ipv6. These are for backward compatibility. 1427 1428 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1429 functionality of interfaces with no corresponding 1430 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1431 and the default address selection policy of ip6addrctl(8) 1432 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1433 Note that if you want to configure IPv6 functionality on the 1434 disabled interfaces after boot, first you need to clear the flag by 1435 using ifconfig(8) like: 1436 1437 ifconfig em0 inet6 -ifdisabled 1438 1439 If YES, the default address selection policy is set as 1440 IPv6-preferred. 1441 1442 The default value of $ipv6_prefer is NO. 1443 1444 4. If your system need to receive Router Advertisement messages, 1445 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1446 scripts automatically invoke rtsol(8) when the interface becomes 1447 UP. The Router Advertisement messages are used for SLAAC 1448 (State-Less Address AutoConfiguration). 1449 145020090922: 1451 802.11s D3.03 support was committed. This is incompatible with the 1452 previous code, which was based on D3.0. 1453 145420090912: 1455 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1456 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1457 control whether accepting Router Advertisement messages or not. 1458 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1459 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1460 The ifconfig(8) utility now supports these flags. 1461 146220090910: 1463 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1464 mount(8) and -a option for df(1) to see them. 1465 146620090825: 1467 The old tunable hw.bus.devctl_disable has been superseded by 1468 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1469 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1470 is 1000. 1471 147220090813: 1473 Remove the option STOP_NMI. The default action is now to use NMI only 1474 for KDB via the newly introduced function stop_cpus_hard() and 1475 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1476 147720090803: 1478 The stable/8 branch created in subversion. This corresponds to the 1479 RELENG_8 branch in CVS. 1480 148120090719: 1482 Bump the shared library version numbers for all libraries that do not 1483 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1484 __FreeBSD_version to 800105. 1485 148620090714: 1487 Due to changes in the implementation of virtual network stack support, 1488 all network-related kernel modules must be recompiled. As this change 1489 breaks the ABI, bump __FreeBSD_version to 800104. 1490 149120090713: 1492 The TOE interface to the TCP syncache has been modified to remove 1493 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1494 The cxgb driver is the only TOE consumer affected by this change, and 1495 needs to be recompiled along with the kernel. As this change breaks 1496 the ABI, bump __FreeBSD_version to 800103. 1497 149820090712: 1499 Padding has been added to struct tcpcb, sackhint and tcpstat in 1500 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1501 maintaining the ABI. However, this change breaks the ABI, so bump 1502 __FreeBSD_version to 800102. User space tools that rely on the size of 1503 any of these structs (e.g. sockstat) need to be recompiled. 1504 150520090630: 1506 The NFS_LEGACYRPC option has been removed along with the old kernel 1507 RPC implementation that this option selected. Kernel configurations 1508 may need to be adjusted. 1509 151020090629: 1511 The network interface device nodes at /dev/net/<interface> have been 1512 removed. All ioctl operations can be performed the normal way using 1513 routing sockets. The kqueue functionality can generally be replaced 1514 with routing sockets. 1515 151620090628: 1517 The documentation from the FreeBSD Documentation Project (Handbook, 1518 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1519 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1520 152120090624: 1522 The ABI of various structures related to the SYSV IPC API have been 1523 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1524 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1525 800100. 1526 152720090622: 1528 Layout of struct vnet has changed as routing related variables were 1529 moved to their own Vimage module. Modules need to be recompiled. Bump 1530 __FreeBSD_version to 800099. 1531 153220090619: 1533 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1534 respectively. As long as no more than 16 groups per process are used, 1535 no changes should be visible. When more than 16 groups are used, old 1536 binaries may fail if they call getgroups() or getgrouplist() with 1537 statically sized storage. Recompiling will work around this, but 1538 applications should be modified to use dynamically allocated storage 1539 for group arrays as POSIX.1-2008 does not cap an implementation's 1540 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1541 1542 NFS and portalfs mounts may also be affected as the list of groups is 1543 truncated to 16. Users of NFS who use more than 16 groups, should 1544 take care that negative group permissions are not used on the exported 1545 file systems as they will not be reliable unless a GSSAPI based 1546 authentication method is used. 1547 154820090616: 1549 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1550 option compiles in the support for adaptive spinning for lockmgrs 1551 which want to enable it. The lockinit() function now accepts the flag 1552 LK_ADAPTIVE in order to make the lock object subject to adaptive 1553 spinning when both held in write and read mode. 1554 155520090613: 1556 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1557 changed. User applications that use this ioctl need to be rebuilt. 1558 155920090611: 1560 The layout of struct thread has changed. Kernel and modules need to 1561 be rebuilt. 1562 156320090608: 1564 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1565 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1566 156720090602: 1568 window(1) has been removed from the base system. It can now be 1569 installed from ports. The port is called misc/window. 1570 157120090601: 1572 The way we are storing and accessing `routing table' entries has 1573 changed. Programs reading the FIB, like netstat, need to be 1574 re-compiled. 1575 157620090601: 1577 A new netisr implementation has been added for FreeBSD 8. Network 1578 file system modules, such as igmp, ipdivert, and others, should be 1579 rebuilt. 1580 Bump __FreeBSD_version to 800096. 1581 158220090530: 1583 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1584 more valid. 1585 158620090530: 1587 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1588 Bump __FreeBSD_version to 800094. 1589 159020090529: 1591 Add mnt_xflag field to 'struct mount'. File system modules need to be 1592 rebuilt. 1593 Bump __FreeBSD_version to 800093. 1594 159520090528: 1596 The compiling option ADAPTIVE_SX has been retired while it has been 1597 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1598 The KPI for sx_init_flags() changes as accepting flags: 1599 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1600 been introduced in order to handle the reversed logic. 1601 Bump __FreeBSD_version to 800092. 1602 160320090527: 1604 Add support for hierarchical jails. Remove global securelevel. 1605 Bump __FreeBSD_version to 800091. 1606 160720090523: 1608 The layout of struct vnet_net has changed, therefore modules 1609 need to be rebuilt. 1610 Bump __FreeBSD_version to 800090. 1611 161220090523: 1613 The newly imported zic(8) produces a new format in the output. Please 1614 run tzsetup(8) to install the newly created data to /etc/localtime. 1615 161620090520: 1617 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1618 hw.usb.* and is now consistent again with previous releases. 1619 162020090520: 1621 802.11 monitor mode support was revised and driver api's were changed. 1622 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1623 of DLT_IEEE802_11. No user-visible data structures were changed but 1624 applications that use DLT_IEEE802_11 may require changes. 1625 Bump __FreeBSD_version to 800088. 1626 162720090430: 1628 The layout of the following structs has changed: sysctl_oid, 1629 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1630 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1631 panics may be experienced. World rebuild is required for 1632 correctly checking networking state from userland. 1633 Bump __FreeBSD_version to 800085. 1634 163520090429: 1636 MLDv2 and Source-Specific Multicast (SSM) have been merged 1637 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1638 The implementation of SSM within FreeBSD's IPv6 stack closely 1639 follows the IPv4 implementation. 1640 1641 For kernel developers: 1642 1643 * The most important changes are that the ip6_output() and 1644 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1645 and this lock has been downgraded to a non-recursive mutex. 1646 1647 * As with the changes to the IPv4 stack to support SSM, filtering 1648 of inbound multicast traffic must now be performed by transport 1649 protocols within the IPv6 stack. This does not apply to TCP and 1650 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1651 1652 * The KPIs used by IPv6 multicast are similar to those used by 1653 the IPv4 stack, with the following differences: 1654 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1655 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1656 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1657 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1658 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1659 for MLDv1 have an additional 'timer' argument which is used to 1660 jitter the initial membership report for the solicited-node 1661 multicast membership on-link. 1662 * This is not strictly needed for MLDv2, which already jitters 1663 its report transmissions. However, the 'timer' argument is 1664 preserved in case MLDv1 is active on the interface. 1665 1666 * The KAME linked-list based IPv6 membership implementation has 1667 been refactored to use a vector similar to that used by the IPv4 1668 stack. 1669 Code which maintains a list of its own multicast memberships 1670 internally, e.g. carp, has been updated to reflect the new 1671 semantics. 1672 1673 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1674 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1675 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1676 implementation constraint which needs to be addressed in HEAD. 1677 1678 For application developers: 1679 1680 * The changes are broadly similar to those made for the IPv4 1681 stack. 1682 1683 * The use of IPv4 and IPv6 multicast socket options on the same 1684 socket, using mapped addresses, HAS NOT been tested or supported. 1685 1686 * There are a number of issues with the implementation of various 1687 IPv6 multicast APIs which need to be resolved in the API surface 1688 before the implementation is fully compatible with KAME userland 1689 use, and these are mostly to do with interface index treatment. 1690 1691 * The literature available discusses the use of either the delta / ASM 1692 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1693 using setsourcefilter(3)/getsourcefilter(3). For more information 1694 please refer to RFC 3768, 'Socket Interface Extensions for 1695 Multicast Source Filters'. 1696 1697 * Applications which use the published RFC 3678 APIs should be fine. 1698 1699 For systems administrators: 1700 1701 * The mtest(8) utility has been refactored to support IPv6, in 1702 addition to IPv4. Interface addresses are no longer accepted 1703 as arguments, their names must be used instead. The utility 1704 will map the interface name to its first IPv4 address as 1705 returned by getifaddrs(3). 1706 1707 * The ifmcstat(8) utility has also been updated to print the MLDv2 1708 endpoint state and source filter lists via sysctl(3). 1709 1710 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1711 loopback of IPv6 multicast datagrams by default; it defaults to 1 1712 to preserve the existing behaviour. Disabling multicast loopback is 1713 recommended for optimal system performance. 1714 1715 * The IPv6 MROUTING code has been changed to examine this sysctl 1716 instead of attempting to perform a group lookup before looping 1717 back forwarded datagrams. 1718 1719 Bump __FreeBSD_version to 800084. 1720 172120090422: 1722 Implement low-level Bluetooth HCI API. 1723 Bump __FreeBSD_version to 800083. 1724 172520090419: 1726 The layout of struct malloc_type, used by modules to register new 1727 memory allocation types, has changed. Most modules will need to 1728 be rebuilt or panics may be experienced. 1729 Bump __FreeBSD_version to 800081. 1730 173120090415: 1732 Anticipate overflowing inp_flags - add inp_flags2. 1733 This changes most offsets in inpcb, so checking v4 connection 1734 state will require a world rebuild. 1735 Bump __FreeBSD_version to 800080. 1736 173720090415: 1738 Add an llentry to struct route and struct route_in6. Modules 1739 embedding a struct route will need to be recompiled. 1740 Bump __FreeBSD_version to 800079. 1741 174220090414: 1743 The size of rt_metrics_lite and by extension rtentry has changed. 1744 Networking administration apps will need to be recompiled. 1745 The route command now supports show as an alias for get, weighting 1746 of routes, sticky and nostick flags to alter the behavior of stateful 1747 load balancing. 1748 Bump __FreeBSD_version to 800078. 1749 175020090408: 1751 Do not use Giant for kbdmux(4) locking. This is wrong and 1752 apparently causing more problems than it solves. This will 1753 re-open the issue where interrupt handlers may race with 1754 kbdmux(4) in polling mode. Typical symptoms include (but 1755 not limited to) duplicated and/or missing characters when 1756 low level console functions (such as gets) are used while 1757 interrupts are enabled (for example geli password prompt, 1758 mountroot prompt etc.). Disabling kbdmux(4) may help. 1759 176020090407: 1761 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1762 kernel modules referencing any of the above need to be recompiled. 1763 Bump __FreeBSD_version to 800075. 1764 176520090320: 1766 GEOM_PART has become the default partition slicer for storage devices, 1767 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1768 introduces some changes: 1769 1770 MSDOS/EBR: the devices created from MSDOS extended partition entries 1771 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1772 to devices with offset-based names. fstabs may need to be modified. 1773 1774 BSD: the "geometry does not match label" warning is harmless in most 1775 cases but it points to problems in file system misalignment with 1776 disk geometry. The "c" partition is now implicit, covers the whole 1777 top-level drive and cannot be (mis)used by users. 1778 1779 General: Kernel dumps are now not allowed to be written to devices 1780 whose partition types indicate they are meant to be used for file 1781 systems (or, in case of MSDOS partitions, as something else than 1782 the "386BSD" type). 1783 1784 Most of these changes date approximately from 200812. 1785 178620090319: 1787 The uscanner(4) driver has been removed from the kernel. This follows 1788 Linux removing theirs in 2.6 and making libusb the default interface 1789 (supported by sane). 1790 179120090319: 1792 The multicast forwarding code has been cleaned up. netstat(1) 1793 only relies on KVM now for printing bandwidth upcall meters. 1794 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1795 ip6_mroute_mod respectively. The config(5) options for statically 1796 compiling this code remain the same, i.e. 'options MROUTING'. 1797 179820090315: 1799 Support for the IFF_NEEDSGIANT network interface flag has been 1800 removed, which means that non-MPSAFE network device drivers are no 1801 longer supported. In particular, if_ar, if_sr, and network device 1802 drivers from the old (legacy) USB stack can no longer be built or 1803 used. 1804 180520090313: 1806 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1807 a bunch of new language catalog files have also been added. 1808 This means that some common libc messages are now localized and 1809 they depend on the LC_MESSAGES environmental variable. 1810 181120090313: 1812 The k8temp(4) driver has been renamed to amdtemp(4) since 1813 support for Family 10 and Family 11 CPU families was added. 1814 181520090309: 1816 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1817 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1818 1819 For kernel developers, the most important changes are that the 1820 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1821 and this lock has been downgraded to a non-recursive mutex. 1822 1823 Transport protocols (UDP, Raw IP) are now responsible for filtering 1824 inbound multicast traffic according to group membership and source 1825 filters. The imo_multicast_filter() KPI exists for this purpose. 1826 Transports which do not use multicast (SCTP, TCP) already reject 1827 multicast by default. Forwarding and receive performance may improve 1828 as a mutex acquisition is no longer needed in the ip_input() 1829 low-level input path. in_addmulti() and in_delmulti() are shimmed 1830 to new KPIs which exist to support SSM in-kernel. 1831 1832 For application developers, it is recommended that loopback of 1833 multicast datagrams be disabled for best performance, as this 1834 will still cause the lock to be taken for each looped-back 1835 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1836 be tuned to 0 to disable loopback by default; it defaults to 1 1837 to preserve the existing behaviour. 1838 1839 For systems administrators, to obtain best performance with 1840 multicast reception and multiple groups, it is always recommended 1841 that a card with a suitably precise hash filter is used. Hash 1842 collisions will still result in the lock being taken within the 1843 transport protocol input path to check group membership. 1844 1845 If deploying FreeBSD in an environment with IGMP snooping switches, 1846 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1847 enabled; this forces 224.0.0.0/24 group membership to be announced 1848 via IGMP. 1849 1850 The size of 'struct igmpstat' has changed; netstat needs to be 1851 recompiled to reflect this. 1852 Bump __FreeBSD_version to 800070. 1853 185420090309: 1855 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1856 updated to use it. This requires a buildworld/installworld in order to 1857 update the library and dependencies (usbconfig, etc). Its advisable to 1858 rebuild all ports which uses libusb. More specific directions are given 1859 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1860 libusb are no longer required and can be removed. 1861 186220090302: 1863 A workaround is committed to allow the creation of System V shared 1864 memory segment of size > 2 GB on the 64-bit architectures. 1865 Due to a limitation of the existing ABI, the shm_segsz member 1866 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1867 wrong for large segments. Note that limits must be explicitly 1868 raised to allow such segments to be created. 1869 187020090301: 1871 The layout of struct ifnet has changed, requiring a rebuild of all 1872 network device driver modules. 1873 187420090227: 1875 The /dev handling for the new USB stack has changed, a 1876 buildworld/installworld is required for libusb20. 1877 187820090223: 1879 The new USB2 stack has now been permanently moved in and all kernel and 1880 module names reverted to their previous values (eg, usb, ehci, ohci, 1881 ums, ...). The old usb stack can be compiled in by prefixing the name 1882 with the letter 'o', the old usb modules have been removed. 1883 Updating entry 20090216 for xorg and 20090215 for libmap may still 1884 apply. 1885 188620090217: 1887 The rc.conf(5) option if_up_delay has been renamed to 1888 defaultroute_delay to better reflect its purpose. If you have 1889 customized this setting in /etc/rc.conf you need to update it to 1890 use the new name. 1891 189220090216: 1893 xorg 7.4 wants to configure its input devices via hald which does not 1894 yet work with USB2. If the keyboard/mouse does not work in xorg then 1895 add 1896 Option "AllowEmptyInput" "off" 1897 to your ServerLayout section. This will cause X to use the configured 1898 kbd and mouse sections from your xorg.conf. 1899 190020090215: 1901 The GENERIC kernels for all architectures now default to the new USB2 1902 stack. No kernel config options or code have been removed so if a 1903 problem arises please report it and optionally revert to the old USB 1904 stack. If you are loading USB kernel modules or have a custom kernel 1905 that includes GENERIC then ensure that usb names are also changed over, 1906 eg uftdi -> usb2_serial_ftdi. 1907 1908 Older programs linked against the ports libusb 0.1 need to be 1909 redirected to the new stack's libusb20. /etc/libmap.conf can 1910 be used for this: 1911 # Map old usb library to new one for usb2 stack 1912 libusb-0.1.so.8 libusb20.so.1 1913 191420090209: 1915 All USB ethernet devices now attach as interfaces under the name ueN 1916 (eg. ue0). This is to provide a predictable name as vendors often 1917 change usb chipsets in a product without notice. 1918 191920090203: 1920 The ichsmb(4) driver has been changed to require SMBus slave 1921 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1922 All of the other SMBus controller drivers require left-justified 1923 slave addresses, so this change makes all the drivers provide the 1924 same interface. 1925 192620090201: 1927 INET6 statistics (struct ip6stat) was updated. 1928 netstat(1) needs to be recompiled. 1929 193020090119: 1931 NTFS has been removed from GENERIC kernel on amd64 to match 1932 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1933 will load ntfs.ko module automatically when NTFS support is 1934 actually needed, unless ntfs.ko is not installed or security 1935 level prohibits loading kernel modules. If either is the case, 1936 "options NTFS" has to be added into kernel config. 1937 193820090115: 1939 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1940 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1941 800061. User space tools that rely on the size of struct tcpcb in 1942 tcp_var.h (e.g. sockstat) need to be recompiled. 1943 194420081225: 1945 ng_tty(4) module updated to match the new TTY subsystem. 1946 Due to API change, user-level applications must be updated. 1947 New API support added to mpd5 CVS and expected to be present 1948 in next mpd5.3 release. 1949 195020081219: 1951 With __FreeBSD_version 800060 the makefs tool is part of 1952 the base system (it was a port). 1953 195420081216: 1955 The afdata and ifnet locks have been changed from mutexes to 1956 rwlocks, network modules will need to be re-compiled. 1957 195820081214: 1959 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1960 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1961 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1962 architecture and 40 bytes on 64-bit architecture. The userland 1963 applications "arp" and "ndp" have been updated accordingly. 1964 The output from "netstat -r" shows only routing entries and 1965 none of the L2 information. 1966 196720081130: 1968 __FreeBSD_version 800057 marks the switchover from the 1969 binary ath hal to source code. Users must add the line: 1970 1971 options AH_SUPPORT_AR5416 1972 1973 to their kernel config files when specifying: 1974 1975 device ath_hal 1976 1977 The ath_hal module no longer exists; the code is now compiled 1978 together with the driver in the ath module. It is now 1979 possible to tailor chip support (i.e. reduce the set of chips 1980 and thereby the code size); consult ath_hal(4) for details. 1981 198220081121: 1983 __FreeBSD_version 800054 adds memory barriers to 1984 <machine/atomic.h>, new interfaces to ifnet to facilitate 1985 multiple hardware transmit queues for cards that support 1986 them, and a lock-less ring-buffer implementation to 1987 enable drivers to more efficiently manage queueing of 1988 packets. 1989 199020081117: 1991 A new version of ZFS (version 13) has been merged to -HEAD. 1992 This version has zpool attribute "listsnapshots" off by 1993 default, which means "zfs list" does not show snapshots, 1994 and is the same as Solaris behavior. 1995 199620081028: 1997 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1998 199920081009: 2000 The uhci, ohci, ehci and slhci USB Host controller drivers have 2001 been put into separate modules. If you load the usb module 2002 separately through loader.conf you will need to load the 2003 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 2004 controller add the following to loader.conf: 2005 2006 uhci_load="YES" 2007 ehci_load="YES" 2008 200920081009: 2010 The ABI used by the PMC toolset has changed. Please keep 2011 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 2012 sync. 2013 201420081009: 2015 atapci kernel module now includes only generic PCI ATA 2016 driver. AHCI driver moved to ataahci kernel module. 2017 All vendor-specific code moved into separate kernel modules: 2018 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 2019 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 2020 atamarvell, atamicron, atanational, atanetcell, atanvidia, 2021 atapromise, ataserverworks, atasiliconimage, atasis, atavia 2022 202320080820: 2024 The TTY subsystem of the kernel has been replaced by a new 2025 implementation, which provides better scalability and an 2026 improved driver model. Most common drivers have been migrated to 2027 the new TTY subsystem, while others have not. The following 2028 drivers have not yet been ported to the new TTY layer: 2029 2030 PCI/ISA: 2031 cy, digi, rc, rp, sio 2032 2033 USB: 2034 ubser, ucycom 2035 2036 Line disciplines: 2037 ng_h4, ng_tty, ppp, sl, snp 2038 2039 Adding these drivers to your kernel configuration file shall 2040 cause compilation to fail. 2041 204220080818: 2043 ntpd has been upgraded to 4.2.4p5. 2044 204520080801: 2046 OpenSSH has been upgraded to 5.1p1. 2047 2048 For many years, FreeBSD's version of OpenSSH preferred DSA 2049 over RSA for host and user authentication keys. With this 2050 upgrade, we've switched to the vendor's default of RSA over 2051 DSA. This may cause upgraded clients to warn about unknown 2052 host keys even for previously known hosts. Users should 2053 follow the usual procedure for verifying host keys before 2054 accepting the RSA key. 2055 2056 This can be circumvented by setting the "HostKeyAlgorithms" 2057 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2058 command line. 2059 2060 Please note that the sequence of keys offered for 2061 authentication has been changed as well. You may want to 2062 specify IdentityFile in a different order to revert this 2063 behavior. 2064 206520080713: 2066 The sio(4) driver has been removed from the i386 and amd64 2067 kernel configuration files. This means uart(4) is now the 2068 default serial port driver on those platforms as well. 2069 2070 To prevent collisions with the sio(4) driver, the uart(4) driver 2071 uses different names for its device nodes. This means the 2072 onboard serial port will now most likely be called "ttyu0" 2073 instead of "ttyd0". You may need to reconfigure applications to 2074 use the new device names. 2075 2076 When using the serial port as a boot console, be sure to update 2077 /boot/device.hints and /etc/ttys before booting the new kernel. 2078 If you forget to do so, you can still manually specify the hints 2079 at the loader prompt: 2080 2081 set hint.uart.0.at="isa" 2082 set hint.uart.0.port="0x3F8" 2083 set hint.uart.0.flags="0x10" 2084 set hint.uart.0.irq="4" 2085 boot -s 2086 208720080609: 2088 The gpt(8) utility has been removed. Use gpart(8) to partition 2089 disks instead. 2090 209120080603: 2092 The version that Linuxulator emulates was changed from 2.4.2 2093 to 2.6.16. If you experience any problems with Linux binaries 2094 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2095 if it fixes the problem contact emulation mailing list. 2096 209720080525: 2098 ISDN4BSD (I4B) was removed from the src tree. You may need to 2099 update a your kernel configuration and remove relevant entries. 2100 210120080509: 2102 I have checked in code to support multiple routing tables. 2103 See the man pages setfib(1) and setfib(2). 2104 This is a hopefully backwards compatible version, 2105 but to make use of it you need to compile your kernel 2106 with options ROUTETABLES=2 (or more up to 16). 2107 210820080420: 2109 The 802.11 wireless support was redone to enable multi-bss 2110 operation on devices that are capable. The underlying device 2111 is no longer used directly but instead wlanX devices are 2112 cloned with ifconfig. This requires changes to rc.conf files. 2113 For example, change: 2114 ifconfig_ath0="WPA DHCP" 2115 to 2116 wlans_ath0=wlan0 2117 ifconfig_wlan0="WPA DHCP" 2118 see rc.conf(5) for more details. In addition, mergemaster of 2119 /etc/rc.d is highly recommended. Simultaneous update of userland 2120 and kernel wouldn't hurt either. 2121 2122 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2123 modules were merged into the base wlan module. All references 2124 to these modules (e.g. in kernel config files) must be removed. 2125 212620080408: 2127 psm(4) has gained write(2) support in native operation level. 2128 Arbitrary commands can be written to /dev/psm%d and status can 2129 be read back from it. Therefore, an application is responsible 2130 for status validation and error recovery. It is a no-op in 2131 other operation levels. 2132 213320080312: 2134 Support for KSE threading has been removed from the kernel. To 2135 run legacy applications linked against KSE libmap.conf may 2136 be used. The following libmap.conf may be used to ensure 2137 compatibility with any prior release: 2138 2139 libpthread.so.1 libthr.so.1 2140 libpthread.so.2 libthr.so.2 2141 libkse.so.3 libthr.so.3 2142 214320080301: 2144 The layout of struct vmspace has changed. This affects libkvm 2145 and any executables that link against libkvm and use the 2146 kvm_getprocs() function. In particular, but not exclusively, 2147 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2148 The effects are minimal, but it's advisable to upgrade world 2149 nonetheless. 2150 215120080229: 2152 The latest em driver no longer has support in it for the 2153 82575 adapter, this is now moved to the igb driver. The 2154 split was done to make new features that are incompatible 2155 with older hardware easier to do. 2156 215720080220: 2158 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2159 likewise the kernel option is now GEOM_LINUX_LVM. 2160 216120080211: 2162 The default NFS mount mode has changed from UDP to TCP for 2163 increased reliability. If you rely on (insecurely) NFS 2164 mounting across a firewall you may need to update your 2165 firewall rules. 2166 216720080208: 2168 Belatedly note the addition of m_collapse for compacting 2169 mbuf chains. 2170 217120080126: 2172 The fts(3) structures have been changed to use adequate 2173 integer types for their members and so to be able to cope 2174 with huge file trees. The old fts(3) ABI is preserved 2175 through symbol versioning in libc, so third-party binaries 2176 using fts(3) should still work, although they will not take 2177 advantage of the extended types. At the same time, some 2178 third-party software might fail to build after this change 2179 due to unportable assumptions made in its source code about 2180 fts(3) structure members. Such software should be fixed 2181 by its vendor or, in the worst case, in the ports tree. 2182 FreeBSD_version 800015 marks this change for the unlikely 2183 case that a portable fix is impossible. 2184 218520080123: 2186 To upgrade to -current after this date, you must be running 2187 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2188 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2189 219020071128: 2191 The ADAPTIVE_GIANT kernel option has been retired because its 2192 functionality is the default now. 2193 219420071118: 2195 The AT keyboard emulation of sunkbd(4) has been turned on 2196 by default. In order to make the special symbols of the Sun 2197 keyboards driven by sunkbd(4) work under X these now have 2198 to be configured the same way as Sun USB keyboards driven 2199 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2200 2201 Option "XkbLayout" "us" 2202 Option "XkbRules" "xorg" 2203 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2204 220520071024: 2206 It has been decided that it is desirable to provide ABI 2207 backwards compatibility to the FreeBSD 4/5/6 versions of the 2208 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2209 broken with the introduction of PCI domain support (see the 2210 20070930 entry). Unfortunately, this required the ABI of 2211 PCIOCGETCONF to be broken again in order to be able to 2212 provide backwards compatibility to the old version of that 2213 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2214 again. As for prominent ports this affects neither pciutils 2215 nor xorg-server this time, the hal port needs to be rebuilt 2216 however. 2217 221820071020: 2219 The misnamed kthread_create() and friends have been renamed 2220 to kproc_create() etc. Many of the callers already 2221 used kproc_start().. 2222 I will return kthread_create() and friends in a while 2223 with implementations that actually create threads, not procs. 2224 Renaming corresponds with version 800002. 2225 222620071010: 2227 RELENG_7 branched. 2228 2229COMMON ITEMS: 2230 2231 General Notes 2232 ------------- 2233 Avoid using make -j when upgrading. While generally safe, there are 2234 sometimes problems using -j to upgrade. If your upgrade fails with 2235 -j, please try again without -j. From time to time in the past there 2236 have been problems using -j with buildworld and/or installworld. This 2237 is especially true when upgrading between "distant" versions (eg one 2238 that cross a major release boundary or several minor releases, or when 2239 several months have passed on the -current branch). 2240 2241 Sometimes, obscure build problems are the result of environment 2242 poisoning. This can happen because the make utility reads its 2243 environment when searching for values for global variables. To run 2244 your build attempts in an "environmental clean room", prefix all make 2245 commands with 'env -i '. See the env(1) manual page for more details. 2246 2247 When upgrading from one major version to another it is generally best 2248 to upgrade to the latest code in the currently installed branch first, 2249 then do an upgrade to the new branch. This is the best-tested upgrade 2250 path, and has the highest probability of being successful. Please try 2251 this approach before reporting problems with a major version upgrade. 2252 2253 When upgrading a live system, having a root shell around before 2254 installing anything can help undo problems. Not having a root shell 2255 around can lead to problems if pam has changed too much from your 2256 starting point to allow continued authentication after the upgrade. 2257 2258 ZFS notes 2259 --------- 2260 When upgrading the boot ZFS pool to a new version, always follow 2261 these two steps: 2262 2263 1.) recompile and reinstall the ZFS boot loader and boot block 2264 (this is part of "make buildworld" and "make installworld") 2265 2266 2.) update the ZFS boot block on your boot drive 2267 2268 The following example updates the ZFS boot block on the first 2269 partition (freebsd-boot) of a GPT partitioned drive ad0: 2270 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2271 2272 Non-boot pools do not need these updates. 2273 2274 To build a kernel 2275 ----------------- 2276 If you are updating from a prior version of FreeBSD (even one just 2277 a few days old), you should follow this procedure. It is the most 2278 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2279 2280 make kernel-toolchain 2281 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2282 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2283 2284 To test a kernel once 2285 --------------------- 2286 If you just want to boot a kernel once (because you are not sure 2287 if it works, or if you want to boot a known bad kernel to provide 2288 debugging information) run 2289 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2290 nextboot -k testkernel 2291 2292 To just build a kernel when you know that it won't mess you up 2293 -------------------------------------------------------------- 2294 This assumes you are already running a CURRENT system. Replace 2295 ${arch} with the architecture of your machine (e.g. "i386", 2296 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2297 2298 cd src/sys/${arch}/conf 2299 config KERNEL_NAME_HERE 2300 cd ../compile/KERNEL_NAME_HERE 2301 make depend 2302 make 2303 make install 2304 2305 If this fails, go to the "To build a kernel" section. 2306 2307 To rebuild everything and install it on the current system. 2308 ----------------------------------------------------------- 2309 # Note: sometimes if you are running current you gotta do more than 2310 # is listed here if you are upgrading from a really old current. 2311 2312 <make sure you have good level 0 dumps> 2313 make buildworld 2314 make kernel KERNCONF=YOUR_KERNEL_HERE 2315 [1] 2316 <reboot in single user> [3] 2317 mergemaster -p [5] 2318 make installworld 2319 mergemaster -i [4] 2320 make delete-old [6] 2321 <reboot> 2322 2323 To cross-install current onto a separate partition 2324 -------------------------------------------------- 2325 # In this approach we use a separate partition to hold 2326 # current's root, 'usr', and 'var' directories. A partition 2327 # holding "/", "/usr" and "/var" should be about 2GB in 2328 # size. 2329 2330 <make sure you have good level 0 dumps> 2331 <boot into -stable> 2332 make buildworld 2333 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2334 <maybe newfs current's root partition> 2335 <mount current's root partition on directory ${CURRENT_ROOT}> 2336 make installworld DESTDIR=${CURRENT_ROOT} 2337 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2338 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2339 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2340 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2341 <reboot into current> 2342 <do a "native" rebuild/install as described in the previous section> 2343 <maybe install compatibility libraries from ports/misc/compat*> 2344 <reboot> 2345 2346 2347 To upgrade in-place from stable to current 2348 ---------------------------------------------- 2349 <make sure you have good level 0 dumps> 2350 make buildworld [9] 2351 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2352 [1] 2353 <reboot in single user> [3] 2354 mergemaster -p [5] 2355 make installworld 2356 mergemaster -i [4] 2357 make delete-old [6] 2358 <reboot> 2359 2360 Make sure that you've read the UPDATING file to understand the 2361 tweaks to various things you need. At this point in the life 2362 cycle of current, things change often and you are on your own 2363 to cope. The defaults can also change, so please read ALL of 2364 the UPDATING entries. 2365 2366 Also, if you are tracking -current, you must be subscribed to 2367 freebsd-current@freebsd.org. Make sure that before you update 2368 your sources that you have read and understood all the recent 2369 messages there. If in doubt, please track -stable which has 2370 much fewer pitfalls. 2371 2372 [1] If you have third party modules, such as vmware, you 2373 should disable them at this point so they don't crash your 2374 system on reboot. 2375 2376 [3] From the bootblocks, boot -s, and then do 2377 fsck -p 2378 mount -u / 2379 mount -a 2380 cd src 2381 adjkerntz -i # if CMOS is wall time 2382 Also, when doing a major release upgrade, it is required that 2383 you boot into single user mode to do the installworld. 2384 2385 [4] Note: This step is non-optional. Failure to do this step 2386 can result in a significant reduction in the functionality of the 2387 system. Attempting to do it by hand is not recommended and those 2388 that pursue this avenue should read this file carefully, as well 2389 as the archives of freebsd-current and freebsd-hackers mailing lists 2390 for potential gotchas. The -U option is also useful to consider. 2391 See mergemaster(8) for more information. 2392 2393 [5] Usually this step is a noop. However, from time to time 2394 you may need to do this if you get unknown user in the following 2395 step. It never hurts to do it all the time. You may need to 2396 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2397 install) after the buildworld before this step if you last updated 2398 from current before 20130425 or from -stable before 20130430. 2399 2400 [6] This only deletes old files and directories. Old libraries 2401 can be deleted by "make delete-old-libs", but you have to make 2402 sure that no program is using those libraries anymore. 2403 2404 [8] In order to have a kernel that can run the 4.x binaries needed to 2405 do an installworld, you must include the COMPAT_FREEBSD4 option in 2406 your kernel. Failure to do so may leave you with a system that is 2407 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2408 required to run the 5.x binaries on more recent kernels. And so on 2409 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2410 2411 Make sure that you merge any new devices from GENERIC since the 2412 last time you updated your kernel config file. 2413 2414 [9] When checking out sources, you must include the -P flag to have 2415 cvs prune empty directories. 2416 2417 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2418 "?=" instead of the "=" assignment operator, so that buildworld can 2419 override the CPUTYPE if it needs to. 2420 2421 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2422 not on the command line, or in /etc/make.conf. buildworld will 2423 warn if it is improperly defined. 2424FORMAT: 2425 2426This file contains a list, in reverse chronological order, of major 2427breakages in tracking -current. It is not guaranteed to be a complete 2428list of such breakages, and only contains entries since October 10, 2007. 2429If you need to see UPDATING entries from before that date, you will need 2430to fetch an UPDATING file from an older FreeBSD release. 2431 2432Copyright information: 2433 2434Copyright 1998-2009 M.
