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 1920161206 p43 FreeBSD-SA-16:36.telnetd 20 FreeBSD-SA-16:37.libc 21 FreeBSD-SA-16:38.bhyve 22 FreeBSD-EN-16:19.tzcode 23 FreeBSD-EN-16:20.tzdata 24 25 Fix possible login(1) argument injection in telnetd(8).

[EN-15:20] 156 15720151026: p23 FreeBSD-SA-15:25.ntp 158 159 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 160 161 The configuration file syntax has been changed, thus mergemaster 162 run is recommended. Now the "kod" parameter requires "limited" 163 parameter. If the ntp.conf is not updated, the ntpd will run 164 successfully, but with KoD disabled. 165 16620151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 167 Revised patch to address a regression that prevents NIS from working. 168 16920150929: p21 FreeBSD-SA-15:24.rpcbind 170 171 Fix rpcbind(8) remote denial of service.

[SA-15:02] 290 291 Fix SCTP stream reset vulnerability. [SA-15:03] 292 29320150114: p4 FreeBSD-SA-15:01.openssl 294 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 295 29620141223: p3 FreeBSD-SA-14:31.ntp 297 FreeBSD-EN-14:13.freebsd-update 298 299 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 300 Fix directory deletion issue in freebsd-update. [EN-14:13] 301 30220141217: p2 FreeBSD-SA-14:30.unbound 303 Fix unbound remote denial of service vulnerability. 304 30520141210: p1 FreeBSD-SA-14:27.stdio 306 FreeBSD-SA-14:28.file 307 308 Fix buffer overflow in stdio. [SA-14:27] 309 310 Fix multiple vulnerabilities in file(1) and libmagic(3). 311 [SA-14:28] 312 31320140904: 314 The ofwfb driver, used to provide a graphics console on PowerPC when 315 using vt(4), no longer allows mmap() of all of physical memory. This 316 will prevent Xorg on PowerPC with some ATI graphics cards from 317 initializing properly unless x11-servers/xorg-server is updated to 318 1.12.4_8 or newer. 319 32020140831: 321 The libatf-c and libatf-c++ major versions were downgraded to 0 and 322 1 respectively to match the upstream numbers. They were out of 323 sync because, when they were originally added to FreeBSD, the 324 upstream versions were not respected. These libraries are private 325 and not yet built by default, so renumbering them should be a 326 non-issue. However, unclean source trees will yield broken test 327 programs once the operator executes "make delete-old-libs" after a 328 "make installworld". 329 330 Additionally, the atf-sh binary was made private by moving it into 331 /usr/libexec/. Already-built shell test programs will keep the 332 path to the old binary so they will break after "make delete-old" 333 is run. 334 335 If you are using WITH_TESTS=yes (not the default), wipe the object 336 tree and rebuild from scratch to prevent spurious test failures. 337 This is only needed once: the misnumbered libraries and misplaced 338 binaries have been added to OptionalObsoleteFiles.inc so they will 339 be removed during a clean upgrade. 340 34120140814: 342 The ixgbe tunables now match their sysctl counterparts, for example: 343 hw.ixgbe.enable_aim => hw.ix.enable_aim 344 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 345 34620140801: 347 The NFSv4.1 server committed by r269398 changes the internal 348 function call interfaces used between the NFS and krpc modules. 349 As such, __FreeBSD_version was bumped. 350 35120140729: 352 The default unbound configuration has been modified to address 353 issues with reverse lookups on networks that use private 354 address ranges. If you use the local_unbound service, run 355 "service local_unbound setup" as root to regenerate your 356 configuration, then "service local_unbound reload" to load the 357 new configuration. 358 35920140717: 360 It is no longer necessary to include the dwarf version in your DEBUG 361 options in your kernel config file. The bug that required it to be 362 placed in the config file has bene fixed. DEBUG should now just 363 contain -g. The build system will automatically update things 364 to do the right thing. 365 36620140715: 367 Several ABI breaking changes were merged to CTL and new iSCSI code. 368 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 369 iscsictl need to be rebuilt to work with a new kernel. 370 37120140708: 372 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 373 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 374 which differs from the behaviour controlled by this knob.) 375 37620140608: 377 On i386 and amd64 systems, the onifconsole flag is now set by default 378 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 379 as a login TTY if it is set in the bootloader as an active kernel 380 console. No changes in behavior should result otherwise. To revert to 381 the previous behavior, set ttyu0 to "off" in /etc/ttys. 382 38320140512: 384 Clang and llvm have been upgraded to 3.4.1 release. 385 38620140321: 387 Clang and llvm have been upgraded to 3.4 release. 388 38920140306: 390 If a Makefile in a tests/ directory was auto-generating a Kyuafile 391 instead of providing an explicit one, this would prevent such 392 Makefile from providing its own Kyuafile in the future during 393 NO_CLEAN builds. This has been fixed in the Makefiles but manual 394 intervention is needed to clean an objdir if you use NO_CLEAN: 395 # find /usr/obj -name Kyuafile | xargs rm -f 396 39720140303: 398 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 399 capability mode support. Please note that enabling the feature in 400 kernel is still highly recommended. 401 40220140227: 403 OpenSSH is now built with sandbox support, and will use sandbox as 404 the default privilege separation method. This requires Capsicum 405 capability mode support in kernel. 406 40720140216: 408 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 409 been deprecated and will not be part of FreeBSD 11.0 and later 410 releases. If you use this driver, please consider switching to 411 the nfe(4) driver instead. 412 41320140120: 414 10.0-RELEASE. 415 41620131216: 417 The behavior of gss_pseudo_random() for the krb5 mechanism 418 has changed, for applications requesting a longer random string 419 than produced by the underlying enctype's pseudo-random() function. 420 In particular, the random string produced from a session key of 421 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 422 be different at the 17th octet and later, after this change. 423 The counter used in the PRF+ construction is now encoded as a 424 big-endian integer in accordance with RFC 4402. 425 __FreeBSD_version is bumped to 1000701. 426 42720131108: 428 The WITHOUT_ATF build knob has been removed and its functionality 429 has been subsumed into the more generic WITHOUT_TESTS. If you were 430 using the former to disable the build of the ATF libraries, you 431 should change your settings to use the latter. 432 43320131031: 434 The default version of mtree is nmtree which is obtained from 435 NetBSD. The output is generally the same, but may vary 436 slightly. If you found you need identical output adding 437 "-F freebsd9" to the command line should do the trick. For the 438 time being, the old mtree is available as fmtree. 439 44020131014: 441 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 442 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 443 1.1.4_8 and verify bsdyml not linked in, before running "make 444 delete-old-libs": 445 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 446 or 447 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 448 44920131010: 450 The rc.d/jail script has been updated to support jail(8) 451 configuration file. The "jail_<jname>_*" rc.conf(5) variables 452 for per-jail configuration are automatically converted to 453 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 454 This is transparently backward compatible. See below about some 455 incompatibilities and rc.conf(5) manual page for more details. 456 457 These variables are now deprecated in favor of jail(8) configuration 458 file. One can use "rc.d/jail config <jname>" command to generate 459 a jail(8) configuration file in /var/run/jail.<jname>.conf without 460 running the jail(8) utility. The default pathname of the 461 configuration file is /etc/jail.conf and can be specified by 462 using $jail_conf or $jail_<jname>_conf variables. 463 464 Please note that jail_devfs_ruleset accepts an integer at 465 this moment. Please consider to rewrite the ruleset name 466 with an integer. 467 46820130930: 469 BIND has been removed from the base system. If all you need 470 is a local resolver, simply enable and start the local_unbound 471 service instead. Otherwise, several versions of BIND are 472 available in the ports tree. The dns/bind99 port is one example. 473 474 With this change, nslookup(1) and dig(1) are no longer in the base 475 system. Users should instead use host(1) and drill(1) which are 476 in the base system. Alternatively, nslookup and dig can 477 be obtained by installing the dns/bind-tools port. 478 47920130916: 480 With the addition of unbound(8), a new unbound user is now 481 required during installworld. "mergemaster -p" can be used to 482 add the user prior to installworld, as documented in the handbook. 483 48420130911: 485 OpenSSH is now built with DNSSEC support, and will by default 486 silently trust signed SSHFP records. This can be controlled with 487 the VerifyHostKeyDNS client configuration setting. DNSSEC support 488 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 489 49020130906: 491 The GNU Compiler Collection and C++ standard library (libstdc++) 492 are no longer built by default on platforms where clang is the system 493 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 494 options in src.conf. 495 49620130905: 497 The PROCDESC kernel option is now part of the GENERIC kernel 498 configuration and is required for the rwhod(8) to work. 499 If you are using custom kernel configuration, you should include 500 'options PROCDESC'. 501 50220130905: 503 The API and ABI related to the Capsicum framework was modified 504 in backward incompatible way. The userland libraries and programs 505 have to be recompiled to work with the new kernel. This includes the 506 following libraries and programs, but the whole buildworld is 507 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 508 kdump, procstat, rwho, rwhod, uniq. 509 51020130903: 511 AES-NI intrinsic support has been added to gcc. The AES-NI module 512 has been updated to use this support. A new gcc is required to build 513 the aesni module on both i386 and amd64. 514 51520130821: 516 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 517 Thus "device padlock_rng" and "device rdrand_rng" should be 518 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 519 52020130813: 521 WITH_ICONV has been split into two feature sets. WITH_ICONV now 522 enables just the iconv* functionality and is now on by default. 523 WITH_LIBICONV_COMPAT enables the libiconv api and link time 524 compatability. Set WITHOUT_ICONV to build the old way. 525 If you have been using WITH_ICONV before, you will very likely 526 need to turn on WITH_LIBICONV_COMPAT. 527 52820130806: 529 INVARIANTS option now enables DEBUG for code with OpenSolaris and 530 Illumos origin, including ZFS. If you have INVARIANTS in your 531 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 532 explicitly. 533 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 534 locks if WITNESS option was set. Because that generated a lot of 535 witness(9) reports and all of them were believed to be false 536 positives, this is no longer done. New option OPENSOLARIS_WITNESS 537 can be used to achieve the previous behavior. 538 53920130806: 540 Timer values in IPv6 data structures now use time_uptime instead 541 of time_second. Although this is not a user-visible functional 542 change, userland utilities which directly use them---ndp(8), 543 rtadvd(8), and rtsold(8) in the base system---need to be updated 544 to r253970 or later. 545 54620130802: 547 find -delete can now delete the pathnames given as arguments, 548 instead of only files found below them or if the pathname did 549 not contain any slashes. Formerly, the following error message 550 would result: 551 552 find: -delete: <path>: relative path potentially not safe 553 554 Deleting the pathnames given as arguments can be prevented 555 without error messages using -mindepth 1 or by changing 556 directory and passing "." as argument to find. This works in the 557 old as well as the new version of find. 558 55920130726: 560 Behavior of devfs rules path matching has been changed. 561 Pattern is now always matched against fully qualified devfs 562 path and slash characters must be explicitly matched by 563 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 564 subdirectories must be reviewed. 565 56620130716: 567 The default ARM ABI has changed to the ARM EABI. The old ABI is 568 incompatible with the ARM EABI and all programs and modules will 569 need to be rebuilt to work with a new kernel. 570 571 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 572 573 NOTE: Support for the old ABI will be removed in the future and 574 users are advised to upgrade. 575 57620130709: 577 pkg_install has been disconnected from the build if you really need it 578 you should add WITH_PKGTOOLS in your src.conf(5). 579 58020130709: 581 Most of network statistics structures were changed to be able 582 keep 64-bits counters. Thus all tools, that work with networking 583 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 584 58520130629: 586 Fix targets that run multiple make's to use && rather than ; 587 so that subsequent steps depend on success of previous. 588 589 NOTE: if building 'universe' with -j* on stable/8 or stable/9 590 it would be better to start the build using bmake, to avoid 591 overloading the machine. 592 59320130618: 594 Fix a bug that allowed a tracing process (e.g. gdb) to write 595 to a memory-mapped file in the traced process's address space 596 even if neither the traced process nor the tracing process had 597 write access to that file. 598 59920130615: 600 CVS has been removed from the base system. An exact copy 601 of the code is available from the devel/cvs port. 602 60320130613: 604 Some people report the following error after the switch to bmake: 605 606 make: illegal option -- J 607 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 608 ... 609 *** [buildworld] Error code 2 610 611 this likely due to an old instance of make in 612 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 613 which src/Makefile will use that blindly, if it exists, so if 614 you see the above error: 615 616 rm -rf `make -V MAKEPATH` 617 618 should resolve it. 619 62020130516: 621 Use bmake by default. 622 Whereas before one could choose to build with bmake via 623 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 624 make. The goal is to remove these knobs for 10-RELEASE. 625 626 It is worth noting that bmake (like gmake) treats the command 627 line as the unit of failure, rather than statements within the 628 command line. Thus '(cd some/where && dosomething)' is safer 629 than 'cd some/where; dosomething'. The '()' allows consistent 630 behavior in parallel build. 631 63220130429: 633 Fix a bug that allows NFS clients to issue READDIR on files. 634 63520130426: 636 The WITHOUT_IDEA option has been removed because 637 the IDEA patent expired. 638 63920130426: 640 The sysctl which controls TRIM support under ZFS has been renamed 641 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 642 enabled by default. 643 64420130425: 645 The mergemaster command now uses the default MAKEOBJDIRPREFIX 646 rather than creating it's own in the temporary directory in 647 order allow access to bootstrapped versions of tools such as 648 install and mtree. When upgrading from version of FreeBSD where 649 the install command does not support -l, you will need to 650 install a new mergemaster command if mergemaster -p is required. 651 This can be accomplished with the command (cd src/usr.sbin/mergemaster 652 && make install). 653 65420130404: 655 Legacy ATA stack, disabled and replaced by new CAM-based one since 656 FreeBSD 9.0, completely removed from the sources. Kernel modules 657 atadisk and atapi*, user-level tools atacontrol and burncd are 658 removed. Kernel option `options ATA_CAM` is now permanently enabled 659 and removed. 660 66120130319: 662 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 663 and socketpair(2). Software, in particular Kerberos, may 664 automatically detect and use these during building. The resulting 665 binaries will not work on older kernels. 666 66720130308: 668 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 669 information, see the respective 20130304 entry). 670 67120130304: 672 Recent commits to callout(9) changed the size of struct callout, 673 so the KBI is probably heavily disturbed. Also, some functions 674 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 675 by macros. Every kernel module using it won't load, so rebuild 676 is requested. 677 678 The ctl device has been re-enabled in GENERIC for i386 and amd64, 679 but does not initialize by default (because of the new CTL_DISABLE 680 option) to save memory. To re-enable it, remove the CTL_DISABLE 681 option from the kernel config file or set kern.cam.ctl.disable=0 682 in /boot/loader.conf. 683 68420130301: 685 The ctl device has been disabled in GENERIC for i386 and amd64. 686 This was done due to the extra memory being allocated at system 687 initialisation time by the ctl driver which was only used if 688 a CAM target device was created. This makes a FreeBSD system 689 unusable on 128MB or less of RAM. 690 69120130208: 692 A new compression method (lz4) has been merged to -HEAD. Please 693 refer to zpool-features(7) for more information. 694 695 Please refer to the "ZFS notes" section of this file for information 696 on upgrading boot ZFS pools. 697 69820130129: 699 A BSD-licensed patch(1) variant has been added and is installed 700 as bsdpatch, being the GNU version the default patch. 701 To inverse the logic and use the BSD-licensed one as default, 702 while having the GNU version installed as gnupatch, rebuild 703 and install world with the WITH_BSD_PATCH knob set. 704 70520130121: 706 Due to the use of the new -l option to install(1) during build 707 and install, you must take care not to directly set the INSTALL 708 make variable in your /etc/make.conf, /etc/src.conf, or on the 709 command line. If you wish to use the -C flag for all installs 710 you may be able to add INSTALL+=-C to /etc/make.conf or 711 /etc/src.conf. 712 71320130118: 714 The install(1) option -M has changed meaning and now takes an 715 argument that is a file or path to append logs to. In the 716 unlikely event that -M was the last option on the command line 717 and the command line contained at least two files and a target 718 directory the first file will have logs appended to it. The -M 719 option served little practical purpose in the last decade so its 720 use is expected to be extremely rare. 721 72220121223: 723 After switching to Clang as the default compiler some users of ZFS 724 on i386 systems started to experience stack overflow kernel panics. 725 Please consider using 'options KSTACK_PAGES=4' in such configurations. 726 72720121222: 728 GEOM_LABEL now mangles label names read from file system metadata. 729 Mangling affect labels containing spaces, non-printable characters, 730 '%' or '"'. Device names in /etc/fstab and other places may need to 731 be updated. 732 73320121217: 734 By default, only the 10 most recent kernel dumps will be saved. To 735 restore the previous behaviour (no limit on the number of kernel dumps 736 stored in the dump directory) add the following line to /etc/rc.conf: 737 738 savecore_flags="" 739 74020121201: 741 With the addition of auditdistd(8), a new auditdistd user is now 742 required during installworld. "mergemaster -p" can be used to 743 add the user prior to installworld, as documented in the handbook. 744 74520121117: 746 The sin6_scope_id member variable in struct sockaddr_in6 is now 747 filled by the kernel before passing the structure to the userland via 748 sysctl or routing socket. This means the KAME-specific embedded scope 749 id in sin6_addr.s6_addr[2] is always cleared in userland application. 750 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 751 __FreeBSD_version is bumped to 1000025. 752 75320121105: 754 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 755 This means that the world and kernel will be compiled with clang 756 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 757 and /usr/bin/cpp. To disable this behavior and revert to building 758 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 759 of current may need to bootstrap WITHOUT_CLANG first if the clang 760 build fails (its compatibility window doesn't extend to the 9 stable 761 branch point). 762 76320121102: 764 The IPFIREWALL_FORWARD kernel option has been removed. Its 765 functionality now turned on by default. 766 76720121023: 768 The ZERO_COPY_SOCKET kernel option has been removed and 769 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 770 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 771 mechanism which is not safe and may result in kernel crashes. 772 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 773 driver supports disposeable external page sized mbuf storage. 774 Proper replacements for both zero-copy mechanisms are under 775 consideration and will eventually lead to complete removal 776 of the two kernel options. 777 77820121023: 779 The IPv4 network stack has been converted to network byte 780 order. The following modules need to be recompiled together 781 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 782 pf(4), ipfw(4), ng_ipfw(4), stf(4). 783 78420121022: 785 Support for non-MPSAFE filesystems was removed from VFS. The 786 VFS_VERSION was bumped, all filesystem modules shall be 787 recompiled. 788 78920121018: 790 All the non-MPSAFE filesystems have been disconnected from 791 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 792 portalfs, smbfs, xfs. 793 79420121016: 795 The interface cloning API and ABI has changed. The following 796 modules need to be recompiled together with kernel: 797 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 798 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 799 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 800 80120121015: 802 The sdhci driver was split in two parts: sdhci (generic SD Host 803 Controller logic) and sdhci_pci (actual hardware driver). 804 No kernel config modifications are required, but if you 805 load sdhc as a module you must switch to sdhci_pci instead. 806 80720121014: 808 Import the FUSE kernel and userland support into base system. 809 81020121013: 811 The GNU sort(1) program has been removed since the BSD-licensed 812 sort(1) has been the default for quite some time and no serious 813 problems have been reported. The corresponding WITH_GNU_SORT 814 knob has also gone. 815 81620121006: 817 The pfil(9) API/ABI for AF_INET family has been changed. Packet 818 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 819 with new kernel. 820 82120121001: 822 The net80211(4) ABI has been changed to allow for improved driver 823 PS-POLL and power-save support. All wireless drivers need to be 824 recompiled to work with the new kernel. 825 82620120913: 827 The random(4) support for the VIA hardware random number 828 generator (`PADLOCK') is no longer enabled unconditionally. 829 Add the padlock_rng device in the custom kernel config if 830 needed. The GENERIC kernels on i386 and amd64 do include the 831 device, so the change only affects the custom kernel 832 configurations. 833 83420120908: 835 The pf(4) packet filter ABI has been changed. pfctl(8) and 836 snmp_pf module need to be recompiled to work with new kernel. 837 83820120828: 839 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 840 to -HEAD. Pools that have empty_bpobj in active state can not be 841 imported read-write with ZFS implementations that do not support 842 this feature. For more information read the zpool-features(5) 843 manual page. 844 84520120727: 846 The sparc64 ZFS loader has been changed to no longer try to auto- 847 detect ZFS providers based on diskN aliases but now requires these 848 to be explicitly listed in the OFW boot-device environment variable. 849 85020120712: 851 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 852 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 853 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 854 85520120712: 856 The following sysctls and tunables have been renamed for consistency 857 with other variables: 858 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 859 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 860 86120120628: 862 The sort utility has been replaced with BSD sort. For now, GNU sort 863 is also available as "gnusort" or the default can be set back to 864 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 865 installed as "bsdsort". 866 86720120611: 868 A new version of ZFS (pool version 5000) has been merged to -HEAD. 869 Starting with this version the old system of ZFS pool versioning 870 is superseded by "feature flags". This concept enables forward 871 compatibility against certain future changes in functionality of ZFS 872 pools. The first read-only compatible "feature flag" for ZFS pools 873 is named "com.delphix:async_destroy". For more information 874 read the new zpool-features(5) manual page. 875 Please refer to the "ZFS notes" section of this file for information 876 on upgrading boot ZFS pools. 877 87820120417: 879 The malloc(3) implementation embedded in libc now uses sources imported 880 as contrib/jemalloc. The most disruptive API change is to 881 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 882 delete it prior to installworld, and optionally re-create it using the 883 new format after rebooting. See malloc.conf(5) for details 884 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 885 NAMESPACE section). 886 88720120328: 888 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 889 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 890 now spelled mips. This is to aid compatibility with third-party 891 software that expects this naming scheme in uname(3). Little-endian 892 settings are unchanged. If you are updating a big-endian mips64 machine 893 from before this change, you may need to set MACHINE_ARCH=mips64 in 894 your environment before the new build system will recognize your machine. 895 89620120306: 897 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 898 platforms. 899 90020120229: 901 Now unix domain sockets behave "as expected" on nullfs(5). Previously 902 nullfs(5) did not pass through all behaviours to the underlying layer, 903 as a result if we bound to a socket on the lower layer we could connect 904 only to the lower path; if we bound to the upper layer we could connect 905 only to the upper path. The new behavior is one can connect to both the 906 lower and the upper paths regardless what layer path one binds to. 907 90820120211: 909 The getifaddrs upgrade path broken with 20111215 has been restored. 910 If you have upgraded in between 20111215 and 20120209 you need to 911 recompile libc again with your kernel. You still need to recompile 912 world to be able to configure CARP but this restriction already 913 comes from 20111215. 914 91520120114: 916 The set_rcvar() function has been removed from /etc/rc.subr. All 917 base and ports rc.d scripts have been updated, so if you have a 918 port installed with a script in /usr/local/etc/rc.d you can either 919 hand-edit the rcvar= line, or reinstall the port. 920 921 An easy way to handle the mass-update of /etc/rc.d: 922 rm /etc/rc.d/* && mergemaster -i 923 92420120109: 925 panic(9) now stops other CPUs in the SMP systems, disables interrupts 926 on the current CPU and prevents other threads from running. 927 This behavior can be reverted using the kern.stop_scheduler_on_panic 928 tunable/sysctl. 929 The new behavior can be incompatible with kern.sync_on_panic. 930 93120111215: 932 The carp(4) facility has been changed significantly. Configuration 933 of the CARP protocol via ifconfig(8) has changed, as well as format 934 of CARP events submitted to devd(8) has changed. See manual pages 935 for more information. The arpbalance feature of carp(4) is currently 936 not supported anymore. 937 938 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 939 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 940 need to be recompiled. 941 94220111122: 943 The acpi_wmi(4) status device /dev/wmistat has been renamed to 944 /dev/wmistat0. 945 94620111108: 947 The option VFS_ALLOW_NONMPSAFE option has been added in order to 948 explicitely support non-MPSAFE filesystems. 949 It is on by default for all supported platform at this present 950 time. 951 95220111101: 953 The broken amd(4) driver has been replaced with esp(4) in the amd64, 954 i386 and pc98 GENERIC kernel configuration files. 955 95620110930: 957 sysinstall has been removed 958 95920110923: 960 The stable/9 branch created in subversion. This corresponds to the 961 RELENG_9 branch in CVS. 962 96320110913: 964 This commit modifies vfs_register() so that it uses a hash 965 calculation to set vfc_typenum, which is enabled by default. 966 The first time a system is booted after this change, the 967 vfc_typenum values will change for all file systems. The 968 main effect of this is a change to the NFS server file handles 969 for file systems that use vfc_typenum in their fsid, such as ZFS. 970 It will, however, prevent vfc_typenum from changing when file 971 systems are loaded in a different order for subsequent reboots. 972 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 973 until you are ready to remount all NFS clients after a reboot. 974 97520110828: 976 Bump the shared library version numbers for libraries that 977 do not use symbol versioning, have changed the ABI compared 978 to stable/8 and which shared library version was not bumped. 979 Done as part of 9.0-RELEASE cycle. 980 98120110815: 982 During the merge of Capsicum features, the fget(9) KPI was modified. 983 This may require the rebuilding of out-of-tree device drivers -- 984 issues have been reported specifically with the nVidia device driver. 985 __FreeBSD_version is bumped to 900041. 986 987 Also, there is a period between 20110811 and 20110814 where the 988 special devices /dev/{stdin,stdout,stderr} did not work correctly. 989 Building world from a kernel during that window may not work. 990 99120110628: 992 The packet filter (pf) code has been updated to OpenBSD 4.5. 993 You need to update userland tools to be in sync with kernel. 994 This update breaks backward compatibility with earlier pfsync(4) 995 versions. Care must be taken when updating redundant firewall setups. 996 99720110608: 998 The following sysctls and tunables are retired on x86 platforms: 999 machdep.hlt_cpus 1000 machdep.hlt_logical_cpus 1001 The following sysctl is retired: 1002 machdep.hyperthreading_allowed 1003 The sysctls were supposed to provide a way to dynamically offline and 1004 online selected CPUs on x86 platforms, but the implementation has not 1005 been reliable especially with SCHED_ULE scheduler. 1006 machdep.hyperthreading_allowed tunable is still available to ignore 1007 hyperthreading CPUs at OS level. 1008 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 1009 where X is an APIC ID of a CPU. Be advised, though, that disabling 1010 CPUs in non-uniform fashion will result in non-uniform topology and 1011 may lead to sub-optimal system performance with SCHED_ULE, which is 1012 a default scheduler. 1013 101420110607: 1015 cpumask_t type is retired and cpuset_t is used in order to describe 1016 a mask of CPUs. 1017 101820110531: 1019 Changes to ifconfig(8) for dynamic address family detection mandate 1020 that you are running a kernel of 20110525 or later. Make sure to 1021 follow the update procedure to boot a new kernel before installing 1022 world. 1023 102420110513: 1025 Support for sun4v architecture is officially dropped 1026 102720110503: 1028 Several KPI breaking changes have been committed to the mii(4) layer, 1029 the PHY drivers and consequently some Ethernet drivers using mii(4). 1030 This means that miibus.ko and the modules of the affected Ethernet 1031 drivers need to be recompiled. 1032 1033 Note to kernel developers: Given that the OUI bit reversion problem 1034 was fixed as part of these changes all mii(4) commits related to OUIs, 1035 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1036 handling, no longer can be merged verbatim to stable/8 and previous 1037 branches. 1038 103920110430: 1040 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1041 into their kernel configurations along with 'device pci'. 1042 104320110427: 1044 The default NFS client is now the new NFS client, so fstype "newnfs" 1045 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1046 Although mounts via fstype "nfs" will usually work without userland 1047 changes, it is recommended that the mount(8) and mount_nfs(8) 1048 commands be rebuilt from sources and that a link to mount_nfs called 1049 mount_oldnfs be created. The new client is compiled into the 1050 kernel with "options NFSCL" and this is needed for diskless root 1051 file systems. The GENERIC kernel configs have been changed to use 1052 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1053 To use the regular/old client, you can "mount -t oldnfs ...". For 1054 a diskless root file system, you must also include a line like: 1055 1056 vfs.root.mountfrom="oldnfs:" 1057 1058 in the boot/loader.conf on the root fs on the NFS server to make 1059 a diskless root fs use the old client. 1060 106120110424: 1062 The GENERIC kernels for all architectures now default to the new 1063 CAM-based ATA stack. It means that all legacy ATA drivers were 1064 removed and replaced by respective CAM drivers. If you are using 1065 ATA device names in /etc/fstab or other places, make sure to update 1066 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1067 where 'Y's are the sequential numbers starting from zero for each type 1068 in order of detection, unless configured otherwise with tunables, 1069 see cam(4)). There will be symbolic links created in /dev/ to map 1070 old adX devices to the respective adaY. They should provide basic 1071 compatibility for file systems mounting in most cases, but they do 1072 not support old user-level APIs and do not have respective providers 1073 in GEOM. Consider using updated management tools with new device names. 1074 1075 It is possible to load devices ahci, ata, siis and mvs as modules, 1076 but option ATA_CAM should remain in kernel configuration to make ata 1077 module work as CAM driver supporting legacy ATA controllers. Device ata 1078 still can be used in modular fashion (atacore + ...). Modules atadisk 1079 and atapi* are not used and won't affect operation in ATA_CAM mode. 1080 Note that to use CAM-based ATA kernel should include CAM devices 1081 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1082 them are parts of the cam module. 1083 1084 ataraid(4) functionality is now supported by the RAID GEOM class. 1085 To use it you can load geom_raid kernel module and use graid(8) tool 1086 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1087 1088 No kernel config options or code have been removed, so if a problem 1089 arises, please report it and optionally revert to the old ATA stack. 1090 In order to do it you can remove from the kernel config: 1091 options ATA_CAM 1092 device ahci 1093 device mvs 1094 device siis 1095 , and instead add back: 1096 device atadisk # ATA disk drives 1097 device ataraid # ATA RAID drives 1098 device atapicd # ATAPI CDROM drives 1099 device atapifd # ATAPI floppy drives 1100 device atapist # ATAPI tape drives 1101 110220110423: 1103 The default NFS server has been changed to the new server, which 1104 was referred to as the experimental server. If you need to switch 1105 back to the old NFS server, you must now put the "-o" option on 1106 both the mountd and nfsd commands. This can be done using the 1107 mountd_flags and nfs_server_flags rc.conf variables until an 1108 update to the rc scripts is committed, which is coming soon. 1109 111020110418: 1111 The GNU Objective-C runtime library (libobjc), and other Objective-C 1112 related components have been removed from the base system. If you 1113 require an Objective-C library, please use one of the available ports. 1114 111520110331: 1116 ath(4) has been split into bus- and device- modules. if_ath contains 1117 the HAL, the TX rate control and the network device code. if_ath_pci 1118 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1119 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1120 in order to use ath on everything else. 1121 1122 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1123 need to load if_ath and if_ath_pci for ath(4) operation. 1124 112520110314: 1126 As part of the replacement of sysinstall, the process of building 1127 release media has changed significantly. For details, please re-read 1128 release(7), which has been updated to reflect the new build process. 1129 113020110218: 1131 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1132 is the last available version under GPLv2. It brings a number of new 1133 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1134 4.1 and SSE 4.2), better support for powerpc64, a number of new 1135 directives, and lots of other small improvements. See the ChangeLog 1136 file in contrib/binutils for the full details. 1137 113820110218: 1139 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1140 compliant, and will now use half of hash for authentication. 1141 This will break interoperability with all stacks (including all 1142 actual FreeBSD versions) who implement 1143 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1144 authentication). 1145 The only workaround with such peers is to use another HMAC 1146 algorithm for IPsec ("phase 2") authentication. 1147 114820110207: 1149 Remove the uio_yield prototype and symbol. This function has 1150 been misnamed since it was introduced and should not be 1151 globally exposed with this name. The equivalent functionality 1152 is now available using kern_yield(curthread->td_user_pri). 1153 The function remains undocumented. 1154 115520110112: 1156 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1157 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1158 for scalar sysctls is defined but disabled. Code that needs 1159 UQUAD to pass the type checking that must compile on older 1160 systems where the define is not present can check against 1161 __FreeBSD_version >= 900030. 1162 1163 The system dialog(1) has been replaced with a new version previously 1164 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1165 with the previous version, but the libdialog associated with it has 1166 a largely incompatible API. As such, the original version of libdialog 1167 will be kept temporarily as libodialog, until its base system consumers 1168 are replaced or updated. Bump __FreeBSD_version to 900030. 1169 117020110103: 1171 If you are trying to run make universe on a -stable system, and you get 1172 the following warning: 1173 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1174 unknown. config(8) likely too old." 1175 or something similar to it, then you must upgrade your -stable system 1176 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1177 stable/8) or build the config from the latest stable/8 branch and 1178 install it on your system. 1179 1180 Prior to this date, building a current universe on 8-stable system from 1181 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1182 error in the first kernel build phase. A new config on those old 1183 systems will fix that problem for older versions of -current. 1184 118520101228: 1186 The TCP stack has been modified to allow Khelp modules to interact with 1187 it via helper hook points and store per-connection data in the TCP 1188 control block. Bump __FreeBSD_version to 900029. User space tools that 1189 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1190 be recompiled. 1191 119220101114: 1193 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1194 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1195 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1196 to take advantage of it instead of using custom implementations. This 1197 means that these drivers now no longer unconditionally advertise 1198 support for flow control but only do so if flow control is a selected 1199 media option. This was implemented in the generic support that way in 1200 order to allow flow control to be switched on and off via ifconfig(8) 1201 with the PHY specific default to typically off in order to protect 1202 from unwanted effects. Consequently, if you used flow control with 1203 one of the above mentioned drivers you now need to explicitly enable 1204 it, for example via: 1205 ifconfig bge0 media auto mediaopt flowcontrol 1206 1207 Along with the above mentioned changes generic support for setting 1208 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1209 e1000phy(4) as well as ip1000phy(4) have been converted to take 1210 advantage of it. This means that these drivers now no longer take the 1211 link0 parameter for selecting master mode but the master media option 1212 has to be used instead, for example like in the following: 1213 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1214 1215 Selection of master mode now is also available with all other PHY 1216 drivers supporting 1000baseT. 1217 121820101111: 1219 The TCP stack has received a significant update to add support for 1220 modularised congestion control and generally improve the clarity of 1221 congestion control decisions. Bump __FreeBSD_version to 900025. User 1222 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1223 sockstat) need to be recompiled. 1224 122520101002: 1226 The man(1) utility has been replaced by a new version that no longer 1227 uses /etc/manpath.config. Please consult man.conf(5) for how to 1228 migrate local entries to the new format. 1229 123020100928: 1231 The copyright strings printed by login(1) and sshd(8) at the time of a 1232 new connection have been removed to follow other operating systems and 1233 upstream sshd. 1234 123520100915: 1236 A workaround for a fixed ld bug has been removed in kernel code, 1237 so make sure that your system ld is built from sources after 1238 revision 210245 from 2010-07-19 (r211583 if building head kernel 1239 on stable/8, r211584 for stable/7; both from 2010-08-21). 1240 A symptom of incorrect ld version is different addresses for 1241 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1242 124320100913: 1244 The $ipv6_prefer variable in rc.conf(5) has been split into 1245 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1246 1247 The $ip6addrctl_policy is a variable to choose a pre-defined 1248 address selection policy set by ip6addrctl(8). A value 1249 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1250 default is "AUTO". 1251 1252 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1253 flag (see an entry of 20090926) is set on an interface with no 1254 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1255 security reason. If you want IPv6 link-local address on all 1256 interfaces by default, set this to "YES". 1257 1258 The old ipv6_prefer="YES" is equivalent to 1259 ipv6_activate_all_interfaces="YES" and 1260 ip6addrctl_policy="ipv6_prefer". 1261 126220100913: 1263 DTrace has grown support for userland tracing. Due to this, DTrace is 1264 now i386 and amd64 only. 1265 dtruss(1) is now installed by default on those systems and a new 1266 kernel module is needed for userland tracing: fasttrap. 1267 No changes to your kernel config file are necessary to enable 1268 userland tracing, but you might consider adding 'STRIP=' and 1269 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1270 to have informative userland stack traces in DTrace (ustack). 1271 127220100725: 1273 The acpi_aiboost(4) driver has been removed in favor of the new 1274 aibs(4) driver. You should update your kernel configuration file. 1275 127620100722: 1277 BSD grep has been imported to the base system and it is built by 1278 default. It is completely BSD licensed, highly GNU-compatible, uses 1279 less memory than its GNU counterpart and has a small codebase. 1280 However, it is slower than its GNU counterpart, which is mostly 1281 noticeable for larger searches, for smaller ones it is measurable 1282 but not significant. The reason is complex, the most important factor 1283 is that we lack a modern and efficient regex library and GNU 1284 overcomes this by optimizing the searches internally. Future work 1285 on improving the regex performance is planned, for the meantime, 1286 users that need better performance, can build GNU grep instead by 1287 setting the WITH_GNU_GREP knob. 1288 128920100713: 1290 Due to the import of powerpc64 support, all existing powerpc kernel 1291 configuration files must be updated with a machine directive like this: 1292 machine powerpc powerpc 1293 1294 In addition, an updated config(8) is required to build powerpc kernels 1295 after this change. 1296 129720100713: 1298 A new version of ZFS (version 15) has been merged to -HEAD. 1299 This version uses a python library for the following subcommands: 1300 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1301 For full functionality of these commands the following port must 1302 be installed: sysutils/py-zfs 1303 130420100429: 1305 'vm_page's are now hashed by physical address to an array of mutexes. 1306 Currently this is only used to serialize access to hold_count. Over 1307 time the page queue mutex will be peeled away. This changes the size 1308 of pmap on every architecture. And requires all callers of vm_page_hold 1309 and vm_page_unhold to be updated. 1310 131120100402: 1312 WITH_CTF can now be specified in src.conf (not recommended, there 1313 are some problems with static executables), make.conf (would also 1314 affect ports which do not use GNU make and do not override the 1315 compile targets) or in the kernel config (via "makeoptions 1316 WITH_CTF=yes"). 1317 When WITH_CTF was specified there before this was silently ignored, 1318 so make sure that WITH_CTF is not used in places which could lead 1319 to unwanted behavior. 1320 132120100311: 1322 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1323 to allow 32-bit compatibility on non-x86 platforms. All kernel 1324 configurations on amd64 and ia64 platforms using these options must 1325 be modified accordingly. 1326 132720100113: 1328 The utmp user accounting database has been replaced with utmpx, 1329 the user accounting interface standardized by POSIX. 1330 Unfortunately the semantics of utmp and utmpx don't match, 1331 making it practically impossible to support both interfaces. 1332 The user accounting database is used by tools like finger(1), 1333 last(1), talk(1), w(1) and ac(8). 1334 1335 All applications in the base system use utmpx. This means only 1336 local binaries (e.g. from the ports tree) may still use these 1337 utmp database files. These applications must be rebuilt to make 1338 use of utmpx. 1339 1340 After the system has been upgraded, it is safe to remove the old 1341 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1342 assuming their contents is of no importance anymore. Old wtmp 1343 databases can only be used by last(1) and ac(8) after they have 1344 been converted to the new format using wtmpcvt(1). 1345 134620100108: 1347 Introduce the kernel thread "deadlock resolver" (which can be enabled 1348 via the DEADLKRES option, see NOTES for more details) and the 1349 sleepq_type() function for sleepqueues. 1350 135120091202: 1352 The rc.firewall and rc.firewall6 were unified, and 1353 rc.firewall6 and rc.d/ip6fw were removed. 1354 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1355 variables are obsoleted. Instead, the following new rc 1356 variables are added to rc.d/ipfw: 1357 1358 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1359 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1360 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1361 1362 The meanings correspond to the relevant IPv4 variables. 1363 136420091125: 1365 8.0-RELEASE. 1366 136720091113: 1368 The default terminal emulation for syscons(4) has been changed 1369 from cons25 to xterm on all platforms except pc98. This means 1370 that the /etc/ttys file needs to be updated to ensure correct 1371 operation of applications on the console. 1372 1373 The terminal emulation style can be toggled per window by using 1374 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1375 options can be used to change the compile-time default back to 1376 cons25. 1377 1378 To prevent graphical artifacts, make sure the TERM environment 1379 variable is set to match the terminal emulation that is being 1380 performed by syscons(4). 1381 138220091109: 1383 The layout of the structure ieee80211req_scan_result has changed. 1384 Applications that require wireless scan results (e.g. ifconfig(8)) 1385 from net80211 need to be recompiled. 1386 1387 Applications such as wpa_supplicant(8) may require a full world 1388 build without using NO_CLEAN in order to get synchronized with the 1389 new structure. 1390 139120091025: 1392 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1393 There's one kernel module for each firmware. Adding "device iwnfw" 1394 to the kernel configuration file means including all three firmware 1395 images inside the kernel. If you want to include just the one for 1396 your wireless card, use the devices iwn4965fw, iwn5000fw or 1397 iwn5150fw. 1398 139920090926: 1400 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1401 into rc.d/netif. The changes are the following: 1402 1403 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1404 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1405 Note that both variables need the "inet6" keyword at the head. 1406 1407 Do not set $ipv6_network_interfaces manually if you do not 1408 understand what you are doing. It is not needed in most cases. 1409 1410 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1411 they are obsolete. 1412 1413 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1414 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1415 1416 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1417 all configured interfaces have "inet6 accept_rtadv" in the 1418 $ifconfig_IF_ipv6. These are for backward compatibility. 1419 1420 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1421 functionality of interfaces with no corresponding 1422 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1423 and the default address selection policy of ip6addrctl(8) 1424 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1425 Note that if you want to configure IPv6 functionality on the 1426 disabled interfaces after boot, first you need to clear the flag by 1427 using ifconfig(8) like: 1428 1429 ifconfig em0 inet6 -ifdisabled 1430 1431 If YES, the default address selection policy is set as 1432 IPv6-preferred. 1433 1434 The default value of $ipv6_prefer is NO. 1435 1436 4. If your system need to receive Router Advertisement messages, 1437 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1438 scripts automatically invoke rtsol(8) when the interface becomes 1439 UP. The Router Advertisement messages are used for SLAAC 1440 (State-Less Address AutoConfiguration). 1441 144220090922: 1443 802.11s D3.03 support was committed. This is incompatible with the 1444 previous code, which was based on D3.0. 1445 144620090912: 1447 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1448 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1449 control whether accepting Router Advertisement messages or not. 1450 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1451 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1452 The ifconfig(8) utility now supports these flags. 1453 145420090910: 1455 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1456 mount(8) and -a option for df(1) to see them. 1457 145820090825: 1459 The old tunable hw.bus.devctl_disable has been superseded by 1460 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1461 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1462 is 1000. 1463 146420090813: 1465 Remove the option STOP_NMI. The default action is now to use NMI only 1466 for KDB via the newly introduced function stop_cpus_hard() and 1467 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1468 146920090803: 1470 The stable/8 branch created in subversion. This corresponds to the 1471 RELENG_8 branch in CVS. 1472 147320090719: 1474 Bump the shared library version numbers for all libraries that do not 1475 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1476 __FreeBSD_version to 800105. 1477 147820090714: 1479 Due to changes in the implementation of virtual network stack support, 1480 all network-related kernel modules must be recompiled. As this change 1481 breaks the ABI, bump __FreeBSD_version to 800104. 1482 148320090713: 1484 The TOE interface to the TCP syncache has been modified to remove 1485 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1486 The cxgb driver is the only TOE consumer affected by this change, and 1487 needs to be recompiled along with the kernel. As this change breaks 1488 the ABI, bump __FreeBSD_version to 800103. 1489 149020090712: 1491 Padding has been added to struct tcpcb, sackhint and tcpstat in 1492 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1493 maintaining the ABI. However, this change breaks the ABI, so bump 1494 __FreeBSD_version to 800102. User space tools that rely on the size of 1495 any of these structs (e.g. sockstat) need to be recompiled. 1496 149720090630: 1498 The NFS_LEGACYRPC option has been removed along with the old kernel 1499 RPC implementation that this option selected. Kernel configurations 1500 may need to be adjusted. 1501 150220090629: 1503 The network interface device nodes at /dev/net/<interface> have been 1504 removed. All ioctl operations can be performed the normal way using 1505 routing sockets. The kqueue functionality can generally be replaced 1506 with routing sockets. 1507 150820090628: 1509 The documentation from the FreeBSD Documentation Project (Handbook, 1510 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1511 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1512 151320090624: 1514 The ABI of various structures related to the SYSV IPC API have been 1515 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1516 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1517 800100. 1518 151920090622: 1520 Layout of struct vnet has changed as routing related variables were 1521 moved to their own Vimage module. Modules need to be recompiled. Bump 1522 __FreeBSD_version to 800099. 1523 152420090619: 1525 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1526 respectively. As long as no more than 16 groups per process are used, 1527 no changes should be visible. When more than 16 groups are used, old 1528 binaries may fail if they call getgroups() or getgrouplist() with 1529 statically sized storage. Recompiling will work around this, but 1530 applications should be modified to use dynamically allocated storage 1531 for group arrays as POSIX.1-2008 does not cap an implementation's 1532 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1533 1534 NFS and portalfs mounts may also be affected as the list of groups is 1535 truncated to 16. Users of NFS who use more than 16 groups, should 1536 take care that negative group permissions are not used on the exported 1537 file systems as they will not be reliable unless a GSSAPI based 1538 authentication method is used. 1539 154020090616: 1541 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1542 option compiles in the support for adaptive spinning for lockmgrs 1543 which want to enable it. The lockinit() function now accepts the flag 1544 LK_ADAPTIVE in order to make the lock object subject to adaptive 1545 spinning when both held in write and read mode. 1546 154720090613: 1548 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1549 changed. User applications that use this ioctl need to be rebuilt. 1550 155120090611: 1552 The layout of struct thread has changed. Kernel and modules need to 1553 be rebuilt. 1554 155520090608: 1556 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1557 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1558 155920090602: 1560 window(1) has been removed from the base system. It can now be 1561 installed from ports. The port is called misc/window. 1562 156320090601: 1564 The way we are storing and accessing `routing table' entries has 1565 changed. Programs reading the FIB, like netstat, need to be 1566 re-compiled. 1567 156820090601: 1569 A new netisr implementation has been added for FreeBSD 8. Network 1570 file system modules, such as igmp, ipdivert, and others, should be 1571 rebuilt. 1572 Bump __FreeBSD_version to 800096. 1573 157420090530: 1575 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1576 more valid. 1577 157820090530: 1579 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1580 Bump __FreeBSD_version to 800094. 1581 158220090529: 1583 Add mnt_xflag field to 'struct mount'. File system modules need to be 1584 rebuilt. 1585 Bump __FreeBSD_version to 800093. 1586 158720090528: 1588 The compiling option ADAPTIVE_SX has been retired while it has been 1589 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1590 The KPI for sx_init_flags() changes as accepting flags: 1591 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1592 been introduced in order to handle the reversed logic. 1593 Bump __FreeBSD_version to 800092. 1594 159520090527: 1596 Add support for hierarchical jails. Remove global securelevel. 1597 Bump __FreeBSD_version to 800091. 1598 159920090523: 1600 The layout of struct vnet_net has changed, therefore modules 1601 need to be rebuilt. 1602 Bump __FreeBSD_version to 800090. 1603 160420090523: 1605 The newly imported zic(8) produces a new format in the output. Please 1606 run tzsetup(8) to install the newly created data to /etc/localtime. 1607 160820090520: 1609 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1610 hw.usb.* and is now consistent again with previous releases. 1611 161220090520: 1613 802.11 monitor mode support was revised and driver api's were changed. 1614 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1615 of DLT_IEEE802_11. No user-visible data structures were changed but 1616 applications that use DLT_IEEE802_11 may require changes. 1617 Bump __FreeBSD_version to 800088. 1618 161920090430: 1620 The layout of the following structs has changed: sysctl_oid, 1621 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1622 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1623 panics may be experienced. World rebuild is required for 1624 correctly checking networking state from userland. 1625 Bump __FreeBSD_version to 800085. 1626 162720090429: 1628 MLDv2 and Source-Specific Multicast (SSM) have been merged 1629 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1630 The implementation of SSM within FreeBSD's IPv6 stack closely 1631 follows the IPv4 implementation. 1632 1633 For kernel developers: 1634 1635 * The most important changes are that the ip6_output() and 1636 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1637 and this lock has been downgraded to a non-recursive mutex. 1638 1639 * As with the changes to the IPv4 stack to support SSM, filtering 1640 of inbound multicast traffic must now be performed by transport 1641 protocols within the IPv6 stack. This does not apply to TCP and 1642 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1643 1644 * The KPIs used by IPv6 multicast are similar to those used by 1645 the IPv4 stack, with the following differences: 1646 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1647 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1648 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1649 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1650 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1651 for MLDv1 have an additional 'timer' argument which is used to 1652 jitter the initial membership report for the solicited-node 1653 multicast membership on-link. 1654 * This is not strictly needed for MLDv2, which already jitters 1655 its report transmissions. However, the 'timer' argument is 1656 preserved in case MLDv1 is active on the interface. 1657 1658 * The KAME linked-list based IPv6 membership implementation has 1659 been refactored to use a vector similar to that used by the IPv4 1660 stack. 1661 Code which maintains a list of its own multicast memberships 1662 internally, e.g. carp, has been updated to reflect the new 1663 semantics. 1664 1665 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1666 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1667 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1668 implementation constraint which needs to be addressed in HEAD. 1669 1670 For application developers: 1671 1672 * The changes are broadly similar to those made for the IPv4 1673 stack. 1674 1675 * The use of IPv4 and IPv6 multicast socket options on the same 1676 socket, using mapped addresses, HAS NOT been tested or supported. 1677 1678 * There are a number of issues with the implementation of various 1679 IPv6 multicast APIs which need to be resolved in the API surface 1680 before the implementation is fully compatible with KAME userland 1681 use, and these are mostly to do with interface index treatment. 1682 1683 * The literature available discusses the use of either the delta / ASM 1684 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1685 using setsourcefilter(3)/getsourcefilter(3). For more information 1686 please refer to RFC 3768, 'Socket Interface Extensions for 1687 Multicast Source Filters'. 1688 1689 * Applications which use the published RFC 3678 APIs should be fine. 1690 1691 For systems administrators: 1692 1693 * The mtest(8) utility has been refactored to support IPv6, in 1694 addition to IPv4. Interface addresses are no longer accepted 1695 as arguments, their names must be used instead. The utility 1696 will map the interface name to its first IPv4 address as 1697 returned by getifaddrs(3). 1698 1699 * The ifmcstat(8) utility has also been updated to print the MLDv2 1700 endpoint state and source filter lists via sysctl(3). 1701 1702 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1703 loopback of IPv6 multicast datagrams by default; it defaults to 1 1704 to preserve the existing behaviour. Disabling multicast loopback is 1705 recommended for optimal system performance. 1706 1707 * The IPv6 MROUTING code has been changed to examine this sysctl 1708 instead of attempting to perform a group lookup before looping 1709 back forwarded datagrams. 1710 1711 Bump __FreeBSD_version to 800084. 1712 171320090422: 1714 Implement low-level Bluetooth HCI API. 1715 Bump __FreeBSD_version to 800083. 1716 171720090419: 1718 The layout of struct malloc_type, used by modules to register new 1719 memory allocation types, has changed. Most modules will need to 1720 be rebuilt or panics may be experienced. 1721 Bump __FreeBSD_version to 800081. 1722 172320090415: 1724 Anticipate overflowing inp_flags - add inp_flags2. 1725 This changes most offsets in inpcb, so checking v4 connection 1726 state will require a world rebuild. 1727 Bump __FreeBSD_version to 800080. 1728 172920090415: 1730 Add an llentry to struct route and struct route_in6. Modules 1731 embedding a struct route will need to be recompiled. 1732 Bump __FreeBSD_version to 800079. 1733 173420090414: 1735 The size of rt_metrics_lite and by extension rtentry has changed. 1736 Networking administration apps will need to be recompiled. 1737 The route command now supports show as an alias for get, weighting 1738 of routes, sticky and nostick flags to alter the behavior of stateful 1739 load balancing. 1740 Bump __FreeBSD_version to 800078. 1741 174220090408: 1743 Do not use Giant for kbdmux(4) locking. This is wrong and 1744 apparently causing more problems than it solves. This will 1745 re-open the issue where interrupt handlers may race with 1746 kbdmux(4) in polling mode. Typical symptoms include (but 1747 not limited to) duplicated and/or missing characters when 1748 low level console functions (such as gets) are used while 1749 interrupts are enabled (for example geli password prompt, 1750 mountroot prompt etc.). Disabling kbdmux(4) may help. 1751 175220090407: 1753 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1754 kernel modules referencing any of the above need to be recompiled. 1755 Bump __FreeBSD_version to 800075. 1756 175720090320: 1758 GEOM_PART has become the default partition slicer for storage devices, 1759 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1760 introduces some changes: 1761 1762 MSDOS/EBR: the devices created from MSDOS extended partition entries 1763 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1764 to devices with offset-based names. fstabs may need to be modified. 1765 1766 BSD: the "geometry does not match label" warning is harmless in most 1767 cases but it points to problems in file system misalignment with 1768 disk geometry. The "c" partition is now implicit, covers the whole 1769 top-level drive and cannot be (mis)used by users. 1770 1771 General: Kernel dumps are now not allowed to be written to devices 1772 whose partition types indicate they are meant to be used for file 1773 systems (or, in case of MSDOS partitions, as something else than 1774 the "386BSD" type). 1775 1776 Most of these changes date approximately from 200812. 1777 177820090319: 1779 The uscanner(4) driver has been removed from the kernel. This follows 1780 Linux removing theirs in 2.6 and making libusb the default interface 1781 (supported by sane). 1782 178320090319: 1784 The multicast forwarding code has been cleaned up. netstat(1) 1785 only relies on KVM now for printing bandwidth upcall meters. 1786 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1787 ip6_mroute_mod respectively. The config(5) options for statically 1788 compiling this code remain the same, i.e. 'options MROUTING'. 1789 179020090315: 1791 Support for the IFF_NEEDSGIANT network interface flag has been 1792 removed, which means that non-MPSAFE network device drivers are no 1793 longer supported. In particular, if_ar, if_sr, and network device 1794 drivers from the old (legacy) USB stack can no longer be built or 1795 used. 1796 179720090313: 1798 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1799 a bunch of new language catalog files have also been added. 1800 This means that some common libc messages are now localized and 1801 they depend on the LC_MESSAGES environmental variable. 1802 180320090313: 1804 The k8temp(4) driver has been renamed to amdtemp(4) since 1805 support for Family 10 and Family 11 CPU families was added. 1806 180720090309: 1808 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1809 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1810 1811 For kernel developers, the most important changes are that the 1812 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1813 and this lock has been downgraded to a non-recursive mutex. 1814 1815 Transport protocols (UDP, Raw IP) are now responsible for filtering 1816 inbound multicast traffic according to group membership and source 1817 filters. The imo_multicast_filter() KPI exists for this purpose. 1818 Transports which do not use multicast (SCTP, TCP) already reject 1819 multicast by default. Forwarding and receive performance may improve 1820 as a mutex acquisition is no longer needed in the ip_input() 1821 low-level input path. in_addmulti() and in_delmulti() are shimmed 1822 to new KPIs which exist to support SSM in-kernel. 1823 1824 For application developers, it is recommended that loopback of 1825 multicast datagrams be disabled for best performance, as this 1826 will still cause the lock to be taken for each looped-back 1827 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1828 be tuned to 0 to disable loopback by default; it defaults to 1 1829 to preserve the existing behaviour. 1830 1831 For systems administrators, to obtain best performance with 1832 multicast reception and multiple groups, it is always recommended 1833 that a card with a suitably precise hash filter is used. Hash 1834 collisions will still result in the lock being taken within the 1835 transport protocol input path to check group membership. 1836 1837 If deploying FreeBSD in an environment with IGMP snooping switches, 1838 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1839 enabled; this forces 224.0.0.0/24 group membership to be announced 1840 via IGMP. 1841 1842 The size of 'struct igmpstat' has changed; netstat needs to be 1843 recompiled to reflect this. 1844 Bump __FreeBSD_version to 800070. 1845 184620090309: 1847 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1848 updated to use it. This requires a buildworld/installworld in order to 1849 update the library and dependencies (usbconfig, etc). Its advisable to 1850 rebuild all ports which uses libusb. More specific directions are given 1851 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1852 libusb are no longer required and can be removed. 1853 185420090302: 1855 A workaround is committed to allow the creation of System V shared 1856 memory segment of size > 2 GB on the 64-bit architectures. 1857 Due to a limitation of the existing ABI, the shm_segsz member 1858 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1859 wrong for large segments. Note that limits must be explicitly 1860 raised to allow such segments to be created. 1861 186220090301: 1863 The layout of struct ifnet has changed, requiring a rebuild of all 1864 network device driver modules. 1865 186620090227: 1867 The /dev handling for the new USB stack has changed, a 1868 buildworld/installworld is required for libusb20. 1869 187020090223: 1871 The new USB2 stack has now been permanently moved in and all kernel and 1872 module names reverted to their previous values (eg, usb, ehci, ohci, 1873 ums, ...). The old usb stack can be compiled in by prefixing the name 1874 with the letter 'o', the old usb modules have been removed. 1875 Updating entry 20090216 for xorg and 20090215 for libmap may still 1876 apply. 1877 187820090217: 1879 The rc.conf(5) option if_up_delay has been renamed to 1880 defaultroute_delay to better reflect its purpose. If you have 1881 customized this setting in /etc/rc.conf you need to update it to 1882 use the new name. 1883 188420090216: 1885 xorg 7.4 wants to configure its input devices via hald which does not 1886 yet work with USB2. If the keyboard/mouse does not work in xorg then 1887 add 1888 Option "AllowEmptyInput" "off" 1889 to your ServerLayout section. This will cause X to use the configured 1890 kbd and mouse sections from your xorg.conf. 1891 189220090215: 1893 The GENERIC kernels for all architectures now default to the new USB2 1894 stack. No kernel config options or code have been removed so if a 1895 problem arises please report it and optionally revert to the old USB 1896 stack. If you are loading USB kernel modules or have a custom kernel 1897 that includes GENERIC then ensure that usb names are also changed over, 1898 eg uftdi -> usb2_serial_ftdi. 1899 1900 Older programs linked against the ports libusb 0.1 need to be 1901 redirected to the new stack's libusb20. /etc/libmap.conf can 1902 be used for this: 1903 # Map old usb library to new one for usb2 stack 1904 libusb-0.1.so.8 libusb20.so.1 1905 190620090209: 1907 All USB ethernet devices now attach as interfaces under the name ueN 1908 (eg. ue0). This is to provide a predictable name as vendors often 1909 change usb chipsets in a product without notice. 1910 191120090203: 1912 The ichsmb(4) driver has been changed to require SMBus slave 1913 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1914 All of the other SMBus controller drivers require left-justified 1915 slave addresses, so this change makes all the drivers provide the 1916 same interface. 1917 191820090201: 1919 INET6 statistics (struct ip6stat) was updated. 1920 netstat(1) needs to be recompiled. 1921 192220090119: 1923 NTFS has been removed from GENERIC kernel on amd64 to match 1924 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1925 will load ntfs.ko module automatically when NTFS support is 1926 actually needed, unless ntfs.ko is not installed or security 1927 level prohibits loading kernel modules. If either is the case, 1928 "options NTFS" has to be added into kernel config. 1929 193020090115: 1931 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1932 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1933 800061. User space tools that rely on the size of struct tcpcb in 1934 tcp_var.h (e.g. sockstat) need to be recompiled. 1935 193620081225: 1937 ng_tty(4) module updated to match the new TTY subsystem. 1938 Due to API change, user-level applications must be updated. 1939 New API support added to mpd5 CVS and expected to be present 1940 in next mpd5.3 release. 1941 194220081219: 1943 With __FreeBSD_version 800060 the makefs tool is part of 1944 the base system (it was a port). 1945 194620081216: 1947 The afdata and ifnet locks have been changed from mutexes to 1948 rwlocks, network modules will need to be re-compiled. 1949 195020081214: 1951 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1952 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1953 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1954 architecture and 40 bytes on 64-bit architecture. The userland 1955 applications "arp" and "ndp" have been updated accordingly. 1956 The output from "netstat -r" shows only routing entries and 1957 none of the L2 information. 1958 195920081130: 1960 __FreeBSD_version 800057 marks the switchover from the 1961 binary ath hal to source code. Users must add the line: 1962 1963 options AH_SUPPORT_AR5416 1964 1965 to their kernel config files when specifying: 1966 1967 device ath_hal 1968 1969 The ath_hal module no longer exists; the code is now compiled 1970 together with the driver in the ath module. It is now 1971 possible to tailor chip support (i.e. reduce the set of chips 1972 and thereby the code size); consult ath_hal(4) for details. 1973 197420081121: 1975 __FreeBSD_version 800054 adds memory barriers to 1976 <machine/atomic.h>, new interfaces to ifnet to facilitate 1977 multiple hardware transmit queues for cards that support 1978 them, and a lock-less ring-buffer implementation to 1979 enable drivers to more efficiently manage queueing of 1980 packets. 1981 198220081117: 1983 A new version of ZFS (version 13) has been merged to -HEAD. 1984 This version has zpool attribute "listsnapshots" off by 1985 default, which means "zfs list" does not show snapshots, 1986 and is the same as Solaris behavior. 1987 198820081028: 1989 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1990 199120081009: 1992 The uhci, ohci, ehci and slhci USB Host controller drivers have 1993 been put into separate modules. If you load the usb module 1994 separately through loader.conf you will need to load the 1995 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1996 controller add the following to loader.conf: 1997 1998 uhci_load="YES" 1999 ehci_load="YES" 2000 200120081009: 2002 The ABI used by the PMC toolset has changed. Please keep 2003 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 2004 sync. 2005 200620081009: 2007 atapci kernel module now includes only generic PCI ATA 2008 driver. AHCI driver moved to ataahci kernel module. 2009 All vendor-specific code moved into separate kernel modules: 2010 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 2011 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 2012 atamarvell, atamicron, atanational, atanetcell, atanvidia, 2013 atapromise, ataserverworks, atasiliconimage, atasis, atavia 2014 201520080820: 2016 The TTY subsystem of the kernel has been replaced by a new 2017 implementation, which provides better scalability and an 2018 improved driver model. Most common drivers have been migrated to 2019 the new TTY subsystem, while others have not. The following 2020 drivers have not yet been ported to the new TTY layer: 2021 2022 PCI/ISA: 2023 cy, digi, rc, rp, sio 2024 2025 USB: 2026 ubser, ucycom 2027 2028 Line disciplines: 2029 ng_h4, ng_tty, ppp, sl, snp 2030 2031 Adding these drivers to your kernel configuration file shall 2032 cause compilation to fail. 2033 203420080818: 2035 ntpd has been upgraded to 4.2.4p5. 2036 203720080801: 2038 OpenSSH has been upgraded to 5.1p1. 2039 2040 For many years, FreeBSD's version of OpenSSH preferred DSA 2041 over RSA for host and user authentication keys. With this 2042 upgrade, we've switched to the vendor's default of RSA over 2043 DSA. This may cause upgraded clients to warn about unknown 2044 host keys even for previously known hosts. Users should 2045 follow the usual procedure for verifying host keys before 2046 accepting the RSA key. 2047 2048 This can be circumvented by setting the "HostKeyAlgorithms" 2049 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2050 command line. 2051 2052 Please note that the sequence of keys offered for 2053 authentication has been changed as well. You may want to 2054 specify IdentityFile in a different order to revert this 2055 behavior. 2056 205720080713: 2058 The sio(4) driver has been removed from the i386 and amd64 2059 kernel configuration files. This means uart(4) is now the 2060 default serial port driver on those platforms as well. 2061 2062 To prevent collisions with the sio(4) driver, the uart(4) driver 2063 uses different names for its device nodes. This means the 2064 onboard serial port will now most likely be called "ttyu0" 2065 instead of "ttyd0". You may need to reconfigure applications to 2066 use the new device names. 2067 2068 When using the serial port as a boot console, be sure to update 2069 /boot/device.hints and /etc/ttys before booting the new kernel. 2070 If you forget to do so, you can still manually specify the hints 2071 at the loader prompt: 2072 2073 set hint.uart.0.at="isa" 2074 set hint.uart.0.port="0x3F8" 2075 set hint.uart.0.flags="0x10" 2076 set hint.uart.0.irq="4" 2077 boot -s 2078 207920080609: 2080 The gpt(8) utility has been removed. Use gpart(8) to partition 2081 disks instead. 2082 208320080603: 2084 The version that Linuxulator emulates was changed from 2.4.2 2085 to 2.6.16. If you experience any problems with Linux binaries 2086 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2087 if it fixes the problem contact emulation mailing list. 2088 208920080525: 2090 ISDN4BSD (I4B) was removed from the src tree. You may need to 2091 update a your kernel configuration and remove relevant entries. 2092 209320080509: 2094 I have checked in code to support multiple routing tables. 2095 See the man pages setfib(1) and setfib(2). 2096 This is a hopefully backwards compatible version, 2097 but to make use of it you need to compile your kernel 2098 with options ROUTETABLES=2 (or more up to 16). 2099 210020080420: 2101 The 802.11 wireless support was redone to enable multi-bss 2102 operation on devices that are capable. The underlying device 2103 is no longer used directly but instead wlanX devices are 2104 cloned with ifconfig. This requires changes to rc.conf files. 2105 For example, change: 2106 ifconfig_ath0="WPA DHCP" 2107 to 2108 wlans_ath0=wlan0 2109 ifconfig_wlan0="WPA DHCP" 2110 see rc.conf(5) for more details. In addition, mergemaster of 2111 /etc/rc.d is highly recommended. Simultaneous update of userland 2112 and kernel wouldn't hurt either. 2113 2114 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2115 modules were merged into the base wlan module. All references 2116 to these modules (e.g. in kernel config files) must be removed. 2117 211820080408: 2119 psm(4) has gained write(2) support in native operation level. 2120 Arbitrary commands can be written to /dev/psm%d and status can 2121 be read back from it. Therefore, an application is responsible 2122 for status validation and error recovery. It is a no-op in 2123 other operation levels. 2124 212520080312: 2126 Support for KSE threading has been removed from the kernel. To 2127 run legacy applications linked against KSE libmap.conf may 2128 be used. The following libmap.conf may be used to ensure 2129 compatibility with any prior release: 2130 2131 libpthread.so.1 libthr.so.1 2132 libpthread.so.2 libthr.so.2 2133 libkse.so.3 libthr.so.3 2134 213520080301: 2136 The layout of struct vmspace has changed. This affects libkvm 2137 and any executables that link against libkvm and use the 2138 kvm_getprocs() function. In particular, but not exclusively, 2139 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2140 The effects are minimal, but it's advisable to upgrade world 2141 nonetheless. 2142 214320080229: 2144 The latest em driver no longer has support in it for the 2145 82575 adapter, this is now moved to the igb driver. The 2146 split was done to make new features that are incompatible 2147 with older hardware easier to do. 2148 214920080220: 2150 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2151 likewise the kernel option is now GEOM_LINUX_LVM. 2152 215320080211: 2154 The default NFS mount mode has changed from UDP to TCP for 2155 increased reliability. If you rely on (insecurely) NFS 2156 mounting across a firewall you may need to update your 2157 firewall rules. 2158 215920080208: 2160 Belatedly note the addition of m_collapse for compacting 2161 mbuf chains. 2162 216320080126: 2164 The fts(3) structures have been changed to use adequate 2165 integer types for their members and so to be able to cope 2166 with huge file trees. The old fts(3) ABI is preserved 2167 through symbol versioning in libc, so third-party binaries 2168 using fts(3) should still work, although they will not take 2169 advantage of the extended types. At the same time, some 2170 third-party software might fail to build after this change 2171 due to unportable assumptions made in its source code about 2172 fts(3) structure members. Such software should be fixed 2173 by its vendor or, in the worst case, in the ports tree. 2174 FreeBSD_version 800015 marks this change for the unlikely 2175 case that a portable fix is impossible. 2176 217720080123: 2178 To upgrade to -current after this date, you must be running 2179 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2180 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2181 218220071128: 2183 The ADAPTIVE_GIANT kernel option has been retired because its 2184 functionality is the default now. 2185 218620071118: 2187 The AT keyboard emulation of sunkbd(4) has been turned on 2188 by default. In order to make the special symbols of the Sun 2189 keyboards driven by sunkbd(4) work under X these now have 2190 to be configured the same way as Sun USB keyboards driven 2191 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2192 2193 Option "XkbLayout" "us" 2194 Option "XkbRules" "xorg" 2195 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2196 219720071024: 2198 It has been decided that it is desirable to provide ABI 2199 backwards compatibility to the FreeBSD 4/5/6 versions of the 2200 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2201 broken with the introduction of PCI domain support (see the 2202 20070930 entry). Unfortunately, this required the ABI of 2203 PCIOCGETCONF to be broken again in order to be able to 2204 provide backwards compatibility to the old version of that 2205 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2206 again. As for prominent ports this affects neither pciutils 2207 nor xorg-server this time, the hal port needs to be rebuilt 2208 however. 2209 221020071020: 2211 The misnamed kthread_create() and friends have been renamed 2212 to kproc_create() etc. Many of the callers already 2213 used kproc_start().. 2214 I will return kthread_create() and friends in a while 2215 with implementations that actually create threads, not procs. 2216 Renaming corresponds with version 800002. 2217 221820071010: 2219 RELENG_7 branched. 2220 2221COMMON ITEMS: 2222 2223 General Notes 2224 ------------- 2225 Avoid using make -j when upgrading. While generally safe, there are 2226 sometimes problems using -j to upgrade. If your upgrade fails with 2227 -j, please try again without -j. From time to time in the past there 2228 have been problems using -j with buildworld and/or installworld. This 2229 is especially true when upgrading between "distant" versions (eg one 2230 that cross a major release boundary or several minor releases, or when 2231 several months have passed on the -current branch). 2232 2233 Sometimes, obscure build problems are the result of environment 2234 poisoning. This can happen because the make utility reads its 2235 environment when searching for values for global variables. To run 2236 your build attempts in an "environmental clean room", prefix all make 2237 commands with 'env -i '. See the env(1) manual page for more details. 2238 2239 When upgrading from one major version to another it is generally best 2240 to upgrade to the latest code in the currently installed branch first, 2241 then do an upgrade to the new branch. This is the best-tested upgrade 2242 path, and has the highest probability of being successful. Please try 2243 this approach before reporting problems with a major version upgrade. 2244 2245 When upgrading a live system, having a root shell around before 2246 installing anything can help undo problems. Not having a root shell 2247 around can lead to problems if pam has changed too much from your 2248 starting point to allow continued authentication after the upgrade. 2249 2250 ZFS notes 2251 --------- 2252 When upgrading the boot ZFS pool to a new version, always follow 2253 these two steps: 2254 2255 1.) recompile and reinstall the ZFS boot loader and boot block 2256 (this is part of "make buildworld" and "make installworld") 2257 2258 2.) update the ZFS boot block on your boot drive 2259 2260 The following example updates the ZFS boot block on the first 2261 partition (freebsd-boot) of a GPT partitioned drive ad0: 2262 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2263 2264 Non-boot pools do not need these updates. 2265 2266 To build a kernel 2267 ----------------- 2268 If you are updating from a prior version of FreeBSD (even one just 2269 a few days old), you should follow this procedure. It is the most 2270 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2271 2272 make kernel-toolchain 2273 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2274 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2275 2276 To test a kernel once 2277 --------------------- 2278 If you just want to boot a kernel once (because you are not sure 2279 if it works, or if you want to boot a known bad kernel to provide 2280 debugging information) run 2281 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2282 nextboot -k testkernel 2283 2284 To just build a kernel when you know that it won't mess you up 2285 -------------------------------------------------------------- 2286 This assumes you are already running a CURRENT system. Replace 2287 ${arch} with the architecture of your machine (e.g. "i386", 2288 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2289 2290 cd src/sys/${arch}/conf 2291 config KERNEL_NAME_HERE 2292 cd ../compile/KERNEL_NAME_HERE 2293 make depend 2294 make 2295 make install 2296 2297 If this fails, go to the "To build a kernel" section. 2298 2299 To rebuild everything and install it on the current system. 2300 ----------------------------------------------------------- 2301 # Note: sometimes if you are running current you gotta do more than 2302 # is listed here if you are upgrading from a really old current. 2303 2304 <make sure you have good level 0 dumps> 2305 make buildworld 2306 make kernel KERNCONF=YOUR_KERNEL_HERE 2307 [1] 2308 <reboot in single user> [3] 2309 mergemaster -p [5] 2310 make installworld 2311 mergemaster -i [4] 2312 make delete-old [6] 2313 <reboot> 2314 2315 To cross-install current onto a separate partition 2316 -------------------------------------------------- 2317 # In this approach we use a separate partition to hold 2318 # current's root, 'usr', and 'var' directories. A partition 2319 # holding "/", "/usr" and "/var" should be about 2GB in 2320 # size. 2321 2322 <make sure you have good level 0 dumps> 2323 <boot into -stable> 2324 make buildworld 2325 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2326 <maybe newfs current's root partition> 2327 <mount current's root partition on directory ${CURRENT_ROOT}> 2328 make installworld DESTDIR=${CURRENT_ROOT} 2329 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2330 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2331 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2332 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2333 <reboot into current> 2334 <do a "native" rebuild/install as described in the previous section> 2335 <maybe install compatibility libraries from ports/misc/compat*> 2336 <reboot> 2337 2338 2339 To upgrade in-place from stable to current 2340 ---------------------------------------------- 2341 <make sure you have good level 0 dumps> 2342 make buildworld [9] 2343 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2344 [1] 2345 <reboot in single user> [3] 2346 mergemaster -p [5] 2347 make installworld 2348 mergemaster -i [4] 2349 make delete-old [6] 2350 <reboot> 2351 2352 Make sure that you've read the UPDATING file to understand the 2353 tweaks to various things you need. At this point in the life 2354 cycle of current, things change often and you are on your own 2355 to cope. The defaults can also change, so please read ALL of 2356 the UPDATING entries. 2357 2358 Also, if you are tracking -current, you must be subscribed to 2359 freebsd-current@freebsd.org. Make sure that before you update 2360 your sources that you have read and understood all the recent 2361 messages there. If in doubt, please track -stable which has 2362 much fewer pitfalls. 2363 2364 [1] If you have third party modules, such as vmware, you 2365 should disable them at this point so they don't crash your 2366 system on reboot. 2367 2368 [3] From the bootblocks, boot -s, and then do 2369 fsck -p 2370 mount -u / 2371 mount -a 2372 cd src 2373 adjkerntz -i # if CMOS is wall time 2374 Also, when doing a major release upgrade, it is required that 2375 you boot into single user mode to do the installworld. 2376 2377 [4] Note: This step is non-optional. Failure to do this step 2378 can result in a significant reduction in the functionality of the 2379 system. Attempting to do it by hand is not recommended and those 2380 that pursue this avenue should read this file carefully, as well 2381 as the archives of freebsd-current and freebsd-hackers mailing lists 2382 for potential gotchas. The -U option is also useful to consider. 2383 See mergemaster(8) for more information. 2384 2385 [5] Usually this step is a noop. However, from time to time 2386 you may need to do this if you get unknown user in the following 2387 step. It never hurts to do it all the time. You may need to 2388 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2389 install) after the buildworld before this step if you last updated 2390 from current before 20130425 or from -stable before 20130430. 2391 2392 [6] This only deletes old files and directories. Old libraries 2393 can be deleted by "make delete-old-libs", but you have to make 2394 sure that no program is using those libraries anymore. 2395 2396 [8] In order to have a kernel that can run the 4.x binaries needed to 2397 do an installworld, you must include the COMPAT_FREEBSD4 option in 2398 your kernel. Failure to do so may leave you with a system that is 2399 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2400 required to run the 5.x binaries on more recent kernels. And so on 2401 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2402 2403 Make sure that you merge any new devices from GENERIC since the 2404 last time you updated your kernel config file. 2405 2406 [9] When checking out sources, you must include the -P flag to have 2407 cvs prune empty directories. 2408 2409 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2410 "?=" instead of the "=" assignment operator, so that buildworld can 2411 override the CPUTYPE if it needs to. 2412 2413 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2414 not on the command line, or in /etc/make.conf. buildworld will 2415 warn if it is improperly defined. 2416FORMAT: 2417 2418This file contains a list, in reverse chronological order, of major 2419breakages in tracking -current. It is not guaranteed to be a complete 2420list of such breakages, and only contains entries since October 10, 2007. 2421If you need to see UPDATING entries from before that date, you will need 2422to fetch an UPDATING file from an older FreeBSD release. 2423 2424Copyright information: 2425 2426Copyright 1998-2009 M.
