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 1920161025 p41 FreeBSD-SA-16:15.sysarch [revised] 20 21 Fix incorrect argument validation in sysarch(2).

[EN-15:20] 140 14120151026: p23 FreeBSD-SA-15:25.ntp 142 143 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 144 145 The configuration file syntax has been changed, thus mergemaster 146 run is recommended. Now the "kod" parameter requires "limited" 147 parameter. If the ntp.conf is not updated, the ntpd will run 148 successfully, but with KoD disabled. 149 15020151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 151 Revised patch to address a regression that prevents NIS from working. 152 15320150929: p21 FreeBSD-SA-15:24.rpcbind 154 155 Fix rpcbind(8) remote denial of service.

[SA-15:02] 274 275 Fix SCTP stream reset vulnerability. [SA-15:03] 276 27720150114: p4 FreeBSD-SA-15:01.openssl 278 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 279 28020141223: p3 FreeBSD-SA-14:31.ntp 281 FreeBSD-EN-14:13.freebsd-update 282 283 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 284 Fix directory deletion issue in freebsd-update. [EN-14:13] 285 28620141217: p2 FreeBSD-SA-14:30.unbound 287 Fix unbound remote denial of service vulnerability. 288 28920141210: p1 FreeBSD-SA-14:27.stdio 290 FreeBSD-SA-14:28.file 291 292 Fix buffer overflow in stdio. [SA-14:27] 293 294 Fix multiple vulnerabilities in file(1) and libmagic(3). 295 [SA-14:28] 296 29720140904: 298 The ofwfb driver, used to provide a graphics console on PowerPC when 299 using vt(4), no longer allows mmap() of all of physical memory. This 300 will prevent Xorg on PowerPC with some ATI graphics cards from 301 initializing properly unless x11-servers/xorg-server is updated to 302 1.12.4_8 or newer. 303 30420140831: 305 The libatf-c and libatf-c++ major versions were downgraded to 0 and 306 1 respectively to match the upstream numbers. They were out of 307 sync because, when they were originally added to FreeBSD, the 308 upstream versions were not respected. These libraries are private 309 and not yet built by default, so renumbering them should be a 310 non-issue. However, unclean source trees will yield broken test 311 programs once the operator executes "make delete-old-libs" after a 312 "make installworld". 313 314 Additionally, the atf-sh binary was made private by moving it into 315 /usr/libexec/. Already-built shell test programs will keep the 316 path to the old binary so they will break after "make delete-old" 317 is run. 318 319 If you are using WITH_TESTS=yes (not the default), wipe the object 320 tree and rebuild from scratch to prevent spurious test failures. 321 This is only needed once: the misnumbered libraries and misplaced 322 binaries have been added to OptionalObsoleteFiles.inc so they will 323 be removed during a clean upgrade. 324 32520140814: 326 The ixgbe tunables now match their sysctl counterparts, for example: 327 hw.ixgbe.enable_aim => hw.ix.enable_aim 328 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 329 33020140801: 331 The NFSv4.1 server committed by r269398 changes the internal 332 function call interfaces used between the NFS and krpc modules. 333 As such, __FreeBSD_version was bumped. 334 33520140729: 336 The default unbound configuration has been modified to address 337 issues with reverse lookups on networks that use private 338 address ranges. If you use the local_unbound service, run 339 "service local_unbound setup" as root to regenerate your 340 configuration, then "service local_unbound reload" to load the 341 new configuration. 342 34320140717: 344 It is no longer necessary to include the dwarf version in your DEBUG 345 options in your kernel config file. The bug that required it to be 346 placed in the config file has bene fixed. DEBUG should now just 347 contain -g. The build system will automatically update things 348 to do the right thing. 349 35020140715: 351 Several ABI breaking changes were merged to CTL and new iSCSI code. 352 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 353 iscsictl need to be rebuilt to work with a new kernel. 354 35520140708: 356 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 357 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 358 which differs from the behaviour controlled by this knob.) 359 36020140608: 361 On i386 and amd64 systems, the onifconsole flag is now set by default 362 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 363 as a login TTY if it is set in the bootloader as an active kernel 364 console. No changes in behavior should result otherwise. To revert to 365 the previous behavior, set ttyu0 to "off" in /etc/ttys. 366 36720140512: 368 Clang and llvm have been upgraded to 3.4.1 release. 369 37020140321: 371 Clang and llvm have been upgraded to 3.4 release. 372 37320140306: 374 If a Makefile in a tests/ directory was auto-generating a Kyuafile 375 instead of providing an explicit one, this would prevent such 376 Makefile from providing its own Kyuafile in the future during 377 NO_CLEAN builds. This has been fixed in the Makefiles but manual 378 intervention is needed to clean an objdir if you use NO_CLEAN: 379 # find /usr/obj -name Kyuafile | xargs rm -f 380 38120140303: 382 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 383 capability mode support. Please note that enabling the feature in 384 kernel is still highly recommended. 385 38620140227: 387 OpenSSH is now built with sandbox support, and will use sandbox as 388 the default privilege separation method. This requires Capsicum 389 capability mode support in kernel. 390 39120140216: 392 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 393 been deprecated and will not be part of FreeBSD 11.0 and later 394 releases. If you use this driver, please consider switching to 395 the nfe(4) driver instead. 396 39720140120: 398 10.0-RELEASE. 399 40020131216: 401 The behavior of gss_pseudo_random() for the krb5 mechanism 402 has changed, for applications requesting a longer random string 403 than produced by the underlying enctype's pseudo-random() function. 404 In particular, the random string produced from a session key of 405 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 406 be different at the 17th octet and later, after this change. 407 The counter used in the PRF+ construction is now encoded as a 408 big-endian integer in accordance with RFC 4402. 409 __FreeBSD_version is bumped to 1000701. 410 41120131108: 412 The WITHOUT_ATF build knob has been removed and its functionality 413 has been subsumed into the more generic WITHOUT_TESTS. If you were 414 using the former to disable the build of the ATF libraries, you 415 should change your settings to use the latter. 416 41720131031: 418 The default version of mtree is nmtree which is obtained from 419 NetBSD. The output is generally the same, but may vary 420 slightly. If you found you need identical output adding 421 "-F freebsd9" to the command line should do the trick. For the 422 time being, the old mtree is available as fmtree. 423 42420131014: 425 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 426 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 427 1.1.4_8 and verify bsdyml not linked in, before running "make 428 delete-old-libs": 429 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 430 or 431 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 432 43320131010: 434 The rc.d/jail script has been updated to support jail(8) 435 configuration file. The "jail_<jname>_*" rc.conf(5) variables 436 for per-jail configuration are automatically converted to 437 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 438 This is transparently backward compatible. See below about some 439 incompatibilities and rc.conf(5) manual page for more details. 440 441 These variables are now deprecated in favor of jail(8) configuration 442 file. One can use "rc.d/jail config <jname>" command to generate 443 a jail(8) configuration file in /var/run/jail.<jname>.conf without 444 running the jail(8) utility. The default pathname of the 445 configuration file is /etc/jail.conf and can be specified by 446 using $jail_conf or $jail_<jname>_conf variables. 447 448 Please note that jail_devfs_ruleset accepts an integer at 449 this moment. Please consider to rewrite the ruleset name 450 with an integer. 451 45220130930: 453 BIND has been removed from the base system. If all you need 454 is a local resolver, simply enable and start the local_unbound 455 service instead. Otherwise, several versions of BIND are 456 available in the ports tree. The dns/bind99 port is one example. 457 458 With this change, nslookup(1) and dig(1) are no longer in the base 459 system. Users should instead use host(1) and drill(1) which are 460 in the base system. Alternatively, nslookup and dig can 461 be obtained by installing the dns/bind-tools port. 462 46320130916: 464 With the addition of unbound(8), a new unbound user is now 465 required during installworld. "mergemaster -p" can be used to 466 add the user prior to installworld, as documented in the handbook. 467 46820130911: 469 OpenSSH is now built with DNSSEC support, and will by default 470 silently trust signed SSHFP records. This can be controlled with 471 the VerifyHostKeyDNS client configuration setting. DNSSEC support 472 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 473 47420130906: 475 The GNU Compiler Collection and C++ standard library (libstdc++) 476 are no longer built by default on platforms where clang is the system 477 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 478 options in src.conf. 479 48020130905: 481 The PROCDESC kernel option is now part of the GENERIC kernel 482 configuration and is required for the rwhod(8) to work. 483 If you are using custom kernel configuration, you should include 484 'options PROCDESC'. 485 48620130905: 487 The API and ABI related to the Capsicum framework was modified 488 in backward incompatible way. The userland libraries and programs 489 have to be recompiled to work with the new kernel. This includes the 490 following libraries and programs, but the whole buildworld is 491 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 492 kdump, procstat, rwho, rwhod, uniq. 493 49420130903: 495 AES-NI intrinsic support has been added to gcc. The AES-NI module 496 has been updated to use this support. A new gcc is required to build 497 the aesni module on both i386 and amd64. 498 49920130821: 500 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 501 Thus "device padlock_rng" and "device rdrand_rng" should be 502 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 503 50420130813: 505 WITH_ICONV has been split into two feature sets. WITH_ICONV now 506 enables just the iconv* functionality and is now on by default. 507 WITH_LIBICONV_COMPAT enables the libiconv api and link time 508 compatability. Set WITHOUT_ICONV to build the old way. 509 If you have been using WITH_ICONV before, you will very likely 510 need to turn on WITH_LIBICONV_COMPAT. 511 51220130806: 513 INVARIANTS option now enables DEBUG for code with OpenSolaris and 514 Illumos origin, including ZFS. If you have INVARIANTS in your 515 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 516 explicitly. 517 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 518 locks if WITNESS option was set. Because that generated a lot of 519 witness(9) reports and all of them were believed to be false 520 positives, this is no longer done. New option OPENSOLARIS_WITNESS 521 can be used to achieve the previous behavior. 522 52320130806: 524 Timer values in IPv6 data structures now use time_uptime instead 525 of time_second. Although this is not a user-visible functional 526 change, userland utilities which directly use them---ndp(8), 527 rtadvd(8), and rtsold(8) in the base system---need to be updated 528 to r253970 or later. 529 53020130802: 531 find -delete can now delete the pathnames given as arguments, 532 instead of only files found below them or if the pathname did 533 not contain any slashes. Formerly, the following error message 534 would result: 535 536 find: -delete: <path>: relative path potentially not safe 537 538 Deleting the pathnames given as arguments can be prevented 539 without error messages using -mindepth 1 or by changing 540 directory and passing "." as argument to find. This works in the 541 old as well as the new version of find. 542 54320130726: 544 Behavior of devfs rules path matching has been changed. 545 Pattern is now always matched against fully qualified devfs 546 path and slash characters must be explicitly matched by 547 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 548 subdirectories must be reviewed. 549 55020130716: 551 The default ARM ABI has changed to the ARM EABI. The old ABI is 552 incompatible with the ARM EABI and all programs and modules will 553 need to be rebuilt to work with a new kernel. 554 555 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 556 557 NOTE: Support for the old ABI will be removed in the future and 558 users are advised to upgrade. 559 56020130709: 561 pkg_install has been disconnected from the build if you really need it 562 you should add WITH_PKGTOOLS in your src.conf(5). 563 56420130709: 565 Most of network statistics structures were changed to be able 566 keep 64-bits counters. Thus all tools, that work with networking 567 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 568 56920130629: 570 Fix targets that run multiple make's to use && rather than ; 571 so that subsequent steps depend on success of previous. 572 573 NOTE: if building 'universe' with -j* on stable/8 or stable/9 574 it would be better to start the build using bmake, to avoid 575 overloading the machine. 576 57720130618: 578 Fix a bug that allowed a tracing process (e.g. gdb) to write 579 to a memory-mapped file in the traced process's address space 580 even if neither the traced process nor the tracing process had 581 write access to that file. 582 58320130615: 584 CVS has been removed from the base system. An exact copy 585 of the code is available from the devel/cvs port. 586 58720130613: 588 Some people report the following error after the switch to bmake: 589 590 make: illegal option -- J 591 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 592 ... 593 *** [buildworld] Error code 2 594 595 this likely due to an old instance of make in 596 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 597 which src/Makefile will use that blindly, if it exists, so if 598 you see the above error: 599 600 rm -rf `make -V MAKEPATH` 601 602 should resolve it. 603 60420130516: 605 Use bmake by default. 606 Whereas before one could choose to build with bmake via 607 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 608 make. The goal is to remove these knobs for 10-RELEASE. 609 610 It is worth noting that bmake (like gmake) treats the command 611 line as the unit of failure, rather than statements within the 612 command line. Thus '(cd some/where && dosomething)' is safer 613 than 'cd some/where; dosomething'. The '()' allows consistent 614 behavior in parallel build. 615 61620130429: 617 Fix a bug that allows NFS clients to issue READDIR on files. 618 61920130426: 620 The WITHOUT_IDEA option has been removed because 621 the IDEA patent expired. 622 62320130426: 624 The sysctl which controls TRIM support under ZFS has been renamed 625 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 626 enabled by default. 627 62820130425: 629 The mergemaster command now uses the default MAKEOBJDIRPREFIX 630 rather than creating it's own in the temporary directory in 631 order allow access to bootstrapped versions of tools such as 632 install and mtree. When upgrading from version of FreeBSD where 633 the install command does not support -l, you will need to 634 install a new mergemaster command if mergemaster -p is required. 635 This can be accomplished with the command (cd src/usr.sbin/mergemaster 636 && make install). 637 63820130404: 639 Legacy ATA stack, disabled and replaced by new CAM-based one since 640 FreeBSD 9.0, completely removed from the sources. Kernel modules 641 atadisk and atapi*, user-level tools atacontrol and burncd are 642 removed. Kernel option `options ATA_CAM` is now permanently enabled 643 and removed. 644 64520130319: 646 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 647 and socketpair(2). Software, in particular Kerberos, may 648 automatically detect and use these during building. The resulting 649 binaries will not work on older kernels. 650 65120130308: 652 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 653 information, see the respective 20130304 entry). 654 65520130304: 656 Recent commits to callout(9) changed the size of struct callout, 657 so the KBI is probably heavily disturbed. Also, some functions 658 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 659 by macros. Every kernel module using it won't load, so rebuild 660 is requested. 661 662 The ctl device has been re-enabled in GENERIC for i386 and amd64, 663 but does not initialize by default (because of the new CTL_DISABLE 664 option) to save memory. To re-enable it, remove the CTL_DISABLE 665 option from the kernel config file or set kern.cam.ctl.disable=0 666 in /boot/loader.conf. 667 66820130301: 669 The ctl device has been disabled in GENERIC for i386 and amd64. 670 This was done due to the extra memory being allocated at system 671 initialisation time by the ctl driver which was only used if 672 a CAM target device was created. This makes a FreeBSD system 673 unusable on 128MB or less of RAM. 674 67520130208: 676 A new compression method (lz4) has been merged to -HEAD. Please 677 refer to zpool-features(7) for more information. 678 679 Please refer to the "ZFS notes" section of this file for information 680 on upgrading boot ZFS pools. 681 68220130129: 683 A BSD-licensed patch(1) variant has been added and is installed 684 as bsdpatch, being the GNU version the default patch. 685 To inverse the logic and use the BSD-licensed one as default, 686 while having the GNU version installed as gnupatch, rebuild 687 and install world with the WITH_BSD_PATCH knob set. 688 68920130121: 690 Due to the use of the new -l option to install(1) during build 691 and install, you must take care not to directly set the INSTALL 692 make variable in your /etc/make.conf, /etc/src.conf, or on the 693 command line. If you wish to use the -C flag for all installs 694 you may be able to add INSTALL+=-C to /etc/make.conf or 695 /etc/src.conf. 696 69720130118: 698 The install(1) option -M has changed meaning and now takes an 699 argument that is a file or path to append logs to. In the 700 unlikely event that -M was the last option on the command line 701 and the command line contained at least two files and a target 702 directory the first file will have logs appended to it. The -M 703 option served little practical purpose in the last decade so its 704 use is expected to be extremely rare. 705 70620121223: 707 After switching to Clang as the default compiler some users of ZFS 708 on i386 systems started to experience stack overflow kernel panics. 709 Please consider using 'options KSTACK_PAGES=4' in such configurations. 710 71120121222: 712 GEOM_LABEL now mangles label names read from file system metadata. 713 Mangling affect labels containing spaces, non-printable characters, 714 '%' or '"'. Device names in /etc/fstab and other places may need to 715 be updated. 716 71720121217: 718 By default, only the 10 most recent kernel dumps will be saved. To 719 restore the previous behaviour (no limit on the number of kernel dumps 720 stored in the dump directory) add the following line to /etc/rc.conf: 721 722 savecore_flags="" 723 72420121201: 725 With the addition of auditdistd(8), a new auditdistd user is now 726 required during installworld. "mergemaster -p" can be used to 727 add the user prior to installworld, as documented in the handbook. 728 72920121117: 730 The sin6_scope_id member variable in struct sockaddr_in6 is now 731 filled by the kernel before passing the structure to the userland via 732 sysctl or routing socket. This means the KAME-specific embedded scope 733 id in sin6_addr.s6_addr[2] is always cleared in userland application. 734 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 735 __FreeBSD_version is bumped to 1000025. 736 73720121105: 738 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 739 This means that the world and kernel will be compiled with clang 740 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 741 and /usr/bin/cpp. To disable this behavior and revert to building 742 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 743 of current may need to bootstrap WITHOUT_CLANG first if the clang 744 build fails (its compatibility window doesn't extend to the 9 stable 745 branch point). 746 74720121102: 748 The IPFIREWALL_FORWARD kernel option has been removed. Its 749 functionality now turned on by default. 750 75120121023: 752 The ZERO_COPY_SOCKET kernel option has been removed and 753 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 754 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 755 mechanism which is not safe and may result in kernel crashes. 756 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 757 driver supports disposeable external page sized mbuf storage. 758 Proper replacements for both zero-copy mechanisms are under 759 consideration and will eventually lead to complete removal 760 of the two kernel options. 761 76220121023: 763 The IPv4 network stack has been converted to network byte 764 order. The following modules need to be recompiled together 765 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 766 pf(4), ipfw(4), ng_ipfw(4), stf(4). 767 76820121022: 769 Support for non-MPSAFE filesystems was removed from VFS. The 770 VFS_VERSION was bumped, all filesystem modules shall be 771 recompiled. 772 77320121018: 774 All the non-MPSAFE filesystems have been disconnected from 775 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 776 portalfs, smbfs, xfs. 777 77820121016: 779 The interface cloning API and ABI has changed. The following 780 modules need to be recompiled together with kernel: 781 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 782 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 783 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 784 78520121015: 786 The sdhci driver was split in two parts: sdhci (generic SD Host 787 Controller logic) and sdhci_pci (actual hardware driver). 788 No kernel config modifications are required, but if you 789 load sdhc as a module you must switch to sdhci_pci instead. 790 79120121014: 792 Import the FUSE kernel and userland support into base system. 793 79420121013: 795 The GNU sort(1) program has been removed since the BSD-licensed 796 sort(1) has been the default for quite some time and no serious 797 problems have been reported. The corresponding WITH_GNU_SORT 798 knob has also gone. 799 80020121006: 801 The pfil(9) API/ABI for AF_INET family has been changed. Packet 802 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 803 with new kernel. 804 80520121001: 806 The net80211(4) ABI has been changed to allow for improved driver 807 PS-POLL and power-save support. All wireless drivers need to be 808 recompiled to work with the new kernel. 809 81020120913: 811 The random(4) support for the VIA hardware random number 812 generator (`PADLOCK') is no longer enabled unconditionally. 813 Add the padlock_rng device in the custom kernel config if 814 needed. The GENERIC kernels on i386 and amd64 do include the 815 device, so the change only affects the custom kernel 816 configurations. 817 81820120908: 819 The pf(4) packet filter ABI has been changed. pfctl(8) and 820 snmp_pf module need to be recompiled to work with new kernel. 821 82220120828: 823 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 824 to -HEAD. Pools that have empty_bpobj in active state can not be 825 imported read-write with ZFS implementations that do not support 826 this feature. For more information read the zpool-features(5) 827 manual page. 828 82920120727: 830 The sparc64 ZFS loader has been changed to no longer try to auto- 831 detect ZFS providers based on diskN aliases but now requires these 832 to be explicitly listed in the OFW boot-device environment variable. 833 83420120712: 835 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 836 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 837 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 838 83920120712: 840 The following sysctls and tunables have been renamed for consistency 841 with other variables: 842 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 843 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 844 84520120628: 846 The sort utility has been replaced with BSD sort. For now, GNU sort 847 is also available as "gnusort" or the default can be set back to 848 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 849 installed as "bsdsort". 850 85120120611: 852 A new version of ZFS (pool version 5000) has been merged to -HEAD. 853 Starting with this version the old system of ZFS pool versioning 854 is superseded by "feature flags". This concept enables forward 855 compatibility against certain future changes in functionality of ZFS 856 pools. The first read-only compatible "feature flag" for ZFS pools 857 is named "com.delphix:async_destroy". For more information 858 read the new zpool-features(5) manual page. 859 Please refer to the "ZFS notes" section of this file for information 860 on upgrading boot ZFS pools. 861 86220120417: 863 The malloc(3) implementation embedded in libc now uses sources imported 864 as contrib/jemalloc. The most disruptive API change is to 865 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 866 delete it prior to installworld, and optionally re-create it using the 867 new format after rebooting. See malloc.conf(5) for details 868 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 869 NAMESPACE section). 870 87120120328: 872 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 873 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 874 now spelled mips. This is to aid compatibility with third-party 875 software that expects this naming scheme in uname(3). Little-endian 876 settings are unchanged. If you are updating a big-endian mips64 machine 877 from before this change, you may need to set MACHINE_ARCH=mips64 in 878 your environment before the new build system will recognize your machine. 879 88020120306: 881 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 882 platforms. 883 88420120229: 885 Now unix domain sockets behave "as expected" on nullfs(5). Previously 886 nullfs(5) did not pass through all behaviours to the underlying layer, 887 as a result if we bound to a socket on the lower layer we could connect 888 only to the lower path; if we bound to the upper layer we could connect 889 only to the upper path. The new behavior is one can connect to both the 890 lower and the upper paths regardless what layer path one binds to. 891 89220120211: 893 The getifaddrs upgrade path broken with 20111215 has been restored. 894 If you have upgraded in between 20111215 and 20120209 you need to 895 recompile libc again with your kernel. You still need to recompile 896 world to be able to configure CARP but this restriction already 897 comes from 20111215. 898 89920120114: 900 The set_rcvar() function has been removed from /etc/rc.subr. All 901 base and ports rc.d scripts have been updated, so if you have a 902 port installed with a script in /usr/local/etc/rc.d you can either 903 hand-edit the rcvar= line, or reinstall the port. 904 905 An easy way to handle the mass-update of /etc/rc.d: 906 rm /etc/rc.d/* && mergemaster -i 907 90820120109: 909 panic(9) now stops other CPUs in the SMP systems, disables interrupts 910 on the current CPU and prevents other threads from running. 911 This behavior can be reverted using the kern.stop_scheduler_on_panic 912 tunable/sysctl. 913 The new behavior can be incompatible with kern.sync_on_panic. 914 91520111215: 916 The carp(4) facility has been changed significantly. Configuration 917 of the CARP protocol via ifconfig(8) has changed, as well as format 918 of CARP events submitted to devd(8) has changed. See manual pages 919 for more information. The arpbalance feature of carp(4) is currently 920 not supported anymore. 921 922 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 923 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 924 need to be recompiled. 925 92620111122: 927 The acpi_wmi(4) status device /dev/wmistat has been renamed to 928 /dev/wmistat0. 929 93020111108: 931 The option VFS_ALLOW_NONMPSAFE option has been added in order to 932 explicitely support non-MPSAFE filesystems. 933 It is on by default for all supported platform at this present 934 time. 935 93620111101: 937 The broken amd(4) driver has been replaced with esp(4) in the amd64, 938 i386 and pc98 GENERIC kernel configuration files. 939 94020110930: 941 sysinstall has been removed 942 94320110923: 944 The stable/9 branch created in subversion. This corresponds to the 945 RELENG_9 branch in CVS. 946 94720110913: 948 This commit modifies vfs_register() so that it uses a hash 949 calculation to set vfc_typenum, which is enabled by default. 950 The first time a system is booted after this change, the 951 vfc_typenum values will change for all file systems. The 952 main effect of this is a change to the NFS server file handles 953 for file systems that use vfc_typenum in their fsid, such as ZFS. 954 It will, however, prevent vfc_typenum from changing when file 955 systems are loaded in a different order for subsequent reboots. 956 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 957 until you are ready to remount all NFS clients after a reboot. 958 95920110828: 960 Bump the shared library version numbers for libraries that 961 do not use symbol versioning, have changed the ABI compared 962 to stable/8 and which shared library version was not bumped. 963 Done as part of 9.0-RELEASE cycle. 964 96520110815: 966 During the merge of Capsicum features, the fget(9) KPI was modified. 967 This may require the rebuilding of out-of-tree device drivers -- 968 issues have been reported specifically with the nVidia device driver. 969 __FreeBSD_version is bumped to 900041. 970 971 Also, there is a period between 20110811 and 20110814 where the 972 special devices /dev/{stdin,stdout,stderr} did not work correctly. 973 Building world from a kernel during that window may not work. 974 97520110628: 976 The packet filter (pf) code has been updated to OpenBSD 4.5. 977 You need to update userland tools to be in sync with kernel. 978 This update breaks backward compatibility with earlier pfsync(4) 979 versions. Care must be taken when updating redundant firewall setups. 980 98120110608: 982 The following sysctls and tunables are retired on x86 platforms: 983 machdep.hlt_cpus 984 machdep.hlt_logical_cpus 985 The following sysctl is retired: 986 machdep.hyperthreading_allowed 987 The sysctls were supposed to provide a way to dynamically offline and 988 online selected CPUs on x86 platforms, but the implementation has not 989 been reliable especially with SCHED_ULE scheduler. 990 machdep.hyperthreading_allowed tunable is still available to ignore 991 hyperthreading CPUs at OS level. 992 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 993 where X is an APIC ID of a CPU. Be advised, though, that disabling 994 CPUs in non-uniform fashion will result in non-uniform topology and 995 may lead to sub-optimal system performance with SCHED_ULE, which is 996 a default scheduler. 997 99820110607: 999 cpumask_t type is retired and cpuset_t is used in order to describe 1000 a mask of CPUs. 1001 100220110531: 1003 Changes to ifconfig(8) for dynamic address family detection mandate 1004 that you are running a kernel of 20110525 or later. Make sure to 1005 follow the update procedure to boot a new kernel before installing 1006 world. 1007 100820110513: 1009 Support for sun4v architecture is officially dropped 1010 101120110503: 1012 Several KPI breaking changes have been committed to the mii(4) layer, 1013 the PHY drivers and consequently some Ethernet drivers using mii(4). 1014 This means that miibus.ko and the modules of the affected Ethernet 1015 drivers need to be recompiled. 1016 1017 Note to kernel developers: Given that the OUI bit reversion problem 1018 was fixed as part of these changes all mii(4) commits related to OUIs, 1019 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1020 handling, no longer can be merged verbatim to stable/8 and previous 1021 branches. 1022 102320110430: 1024 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1025 into their kernel configurations along with 'device pci'. 1026 102720110427: 1028 The default NFS client is now the new NFS client, so fstype "newnfs" 1029 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1030 Although mounts via fstype "nfs" will usually work without userland 1031 changes, it is recommended that the mount(8) and mount_nfs(8) 1032 commands be rebuilt from sources and that a link to mount_nfs called 1033 mount_oldnfs be created. The new client is compiled into the 1034 kernel with "options NFSCL" and this is needed for diskless root 1035 file systems. The GENERIC kernel configs have been changed to use 1036 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1037 To use the regular/old client, you can "mount -t oldnfs ...". For 1038 a diskless root file system, you must also include a line like: 1039 1040 vfs.root.mountfrom="oldnfs:" 1041 1042 in the boot/loader.conf on the root fs on the NFS server to make 1043 a diskless root fs use the old client. 1044 104520110424: 1046 The GENERIC kernels for all architectures now default to the new 1047 CAM-based ATA stack. It means that all legacy ATA drivers were 1048 removed and replaced by respective CAM drivers. If you are using 1049 ATA device names in /etc/fstab or other places, make sure to update 1050 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1051 where 'Y's are the sequential numbers starting from zero for each type 1052 in order of detection, unless configured otherwise with tunables, 1053 see cam(4)). There will be symbolic links created in /dev/ to map 1054 old adX devices to the respective adaY. They should provide basic 1055 compatibility for file systems mounting in most cases, but they do 1056 not support old user-level APIs and do not have respective providers 1057 in GEOM. Consider using updated management tools with new device names. 1058 1059 It is possible to load devices ahci, ata, siis and mvs as modules, 1060 but option ATA_CAM should remain in kernel configuration to make ata 1061 module work as CAM driver supporting legacy ATA controllers. Device ata 1062 still can be used in modular fashion (atacore + ...). Modules atadisk 1063 and atapi* are not used and won't affect operation in ATA_CAM mode. 1064 Note that to use CAM-based ATA kernel should include CAM devices 1065 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1066 them are parts of the cam module. 1067 1068 ataraid(4) functionality is now supported by the RAID GEOM class. 1069 To use it you can load geom_raid kernel module and use graid(8) tool 1070 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1071 1072 No kernel config options or code have been removed, so if a problem 1073 arises, please report it and optionally revert to the old ATA stack. 1074 In order to do it you can remove from the kernel config: 1075 options ATA_CAM 1076 device ahci 1077 device mvs 1078 device siis 1079 , and instead add back: 1080 device atadisk # ATA disk drives 1081 device ataraid # ATA RAID drives 1082 device atapicd # ATAPI CDROM drives 1083 device atapifd # ATAPI floppy drives 1084 device atapist # ATAPI tape drives 1085 108620110423: 1087 The default NFS server has been changed to the new server, which 1088 was referred to as the experimental server. If you need to switch 1089 back to the old NFS server, you must now put the "-o" option on 1090 both the mountd and nfsd commands. This can be done using the 1091 mountd_flags and nfs_server_flags rc.conf variables until an 1092 update to the rc scripts is committed, which is coming soon. 1093 109420110418: 1095 The GNU Objective-C runtime library (libobjc), and other Objective-C 1096 related components have been removed from the base system. If you 1097 require an Objective-C library, please use one of the available ports. 1098 109920110331: 1100 ath(4) has been split into bus- and device- modules. if_ath contains 1101 the HAL, the TX rate control and the network device code. if_ath_pci 1102 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1103 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1104 in order to use ath on everything else. 1105 1106 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1107 need to load if_ath and if_ath_pci for ath(4) operation. 1108 110920110314: 1110 As part of the replacement of sysinstall, the process of building 1111 release media has changed significantly. For details, please re-read 1112 release(7), which has been updated to reflect the new build process. 1113 111420110218: 1115 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1116 is the last available version under GPLv2. It brings a number of new 1117 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1118 4.1 and SSE 4.2), better support for powerpc64, a number of new 1119 directives, and lots of other small improvements. See the ChangeLog 1120 file in contrib/binutils for the full details. 1121 112220110218: 1123 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1124 compliant, and will now use half of hash for authentication. 1125 This will break interoperability with all stacks (including all 1126 actual FreeBSD versions) who implement 1127 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1128 authentication). 1129 The only workaround with such peers is to use another HMAC 1130 algorithm for IPsec ("phase 2") authentication. 1131 113220110207: 1133 Remove the uio_yield prototype and symbol. This function has 1134 been misnamed since it was introduced and should not be 1135 globally exposed with this name. The equivalent functionality 1136 is now available using kern_yield(curthread->td_user_pri). 1137 The function remains undocumented. 1138 113920110112: 1140 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1141 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1142 for scalar sysctls is defined but disabled. Code that needs 1143 UQUAD to pass the type checking that must compile on older 1144 systems where the define is not present can check against 1145 __FreeBSD_version >= 900030. 1146 1147 The system dialog(1) has been replaced with a new version previously 1148 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1149 with the previous version, but the libdialog associated with it has 1150 a largely incompatible API. As such, the original version of libdialog 1151 will be kept temporarily as libodialog, until its base system consumers 1152 are replaced or updated. Bump __FreeBSD_version to 900030. 1153 115420110103: 1155 If you are trying to run make universe on a -stable system, and you get 1156 the following warning: 1157 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1158 unknown. config(8) likely too old." 1159 or something similar to it, then you must upgrade your -stable system 1160 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1161 stable/8) or build the config from the latest stable/8 branch and 1162 install it on your system. 1163 1164 Prior to this date, building a current universe on 8-stable system from 1165 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1166 error in the first kernel build phase. A new config on those old 1167 systems will fix that problem for older versions of -current. 1168 116920101228: 1170 The TCP stack has been modified to allow Khelp modules to interact with 1171 it via helper hook points and store per-connection data in the TCP 1172 control block. Bump __FreeBSD_version to 900029. User space tools that 1173 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1174 be recompiled. 1175 117620101114: 1177 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1178 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1179 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1180 to take advantage of it instead of using custom implementations. This 1181 means that these drivers now no longer unconditionally advertise 1182 support for flow control but only do so if flow control is a selected 1183 media option. This was implemented in the generic support that way in 1184 order to allow flow control to be switched on and off via ifconfig(8) 1185 with the PHY specific default to typically off in order to protect 1186 from unwanted effects. Consequently, if you used flow control with 1187 one of the above mentioned drivers you now need to explicitly enable 1188 it, for example via: 1189 ifconfig bge0 media auto mediaopt flowcontrol 1190 1191 Along with the above mentioned changes generic support for setting 1192 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1193 e1000phy(4) as well as ip1000phy(4) have been converted to take 1194 advantage of it. This means that these drivers now no longer take the 1195 link0 parameter for selecting master mode but the master media option 1196 has to be used instead, for example like in the following: 1197 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1198 1199 Selection of master mode now is also available with all other PHY 1200 drivers supporting 1000baseT. 1201 120220101111: 1203 The TCP stack has received a significant update to add support for 1204 modularised congestion control and generally improve the clarity of 1205 congestion control decisions. Bump __FreeBSD_version to 900025. User 1206 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1207 sockstat) need to be recompiled. 1208 120920101002: 1210 The man(1) utility has been replaced by a new version that no longer 1211 uses /etc/manpath.config. Please consult man.conf(5) for how to 1212 migrate local entries to the new format. 1213 121420100928: 1215 The copyright strings printed by login(1) and sshd(8) at the time of a 1216 new connection have been removed to follow other operating systems and 1217 upstream sshd. 1218 121920100915: 1220 A workaround for a fixed ld bug has been removed in kernel code, 1221 so make sure that your system ld is built from sources after 1222 revision 210245 from 2010-07-19 (r211583 if building head kernel 1223 on stable/8, r211584 for stable/7; both from 2010-08-21). 1224 A symptom of incorrect ld version is different addresses for 1225 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1226 122720100913: 1228 The $ipv6_prefer variable in rc.conf(5) has been split into 1229 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1230 1231 The $ip6addrctl_policy is a variable to choose a pre-defined 1232 address selection policy set by ip6addrctl(8). A value 1233 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1234 default is "AUTO". 1235 1236 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1237 flag (see an entry of 20090926) is set on an interface with no 1238 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1239 security reason. If you want IPv6 link-local address on all 1240 interfaces by default, set this to "YES". 1241 1242 The old ipv6_prefer="YES" is equivalent to 1243 ipv6_activate_all_interfaces="YES" and 1244 ip6addrctl_policy="ipv6_prefer". 1245 124620100913: 1247 DTrace has grown support for userland tracing. Due to this, DTrace is 1248 now i386 and amd64 only. 1249 dtruss(1) is now installed by default on those systems and a new 1250 kernel module is needed for userland tracing: fasttrap. 1251 No changes to your kernel config file are necessary to enable 1252 userland tracing, but you might consider adding 'STRIP=' and 1253 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1254 to have informative userland stack traces in DTrace (ustack). 1255 125620100725: 1257 The acpi_aiboost(4) driver has been removed in favor of the new 1258 aibs(4) driver. You should update your kernel configuration file. 1259 126020100722: 1261 BSD grep has been imported to the base system and it is built by 1262 default. It is completely BSD licensed, highly GNU-compatible, uses 1263 less memory than its GNU counterpart and has a small codebase. 1264 However, it is slower than its GNU counterpart, which is mostly 1265 noticeable for larger searches, for smaller ones it is measurable 1266 but not significant. The reason is complex, the most important factor 1267 is that we lack a modern and efficient regex library and GNU 1268 overcomes this by optimizing the searches internally. Future work 1269 on improving the regex performance is planned, for the meantime, 1270 users that need better performance, can build GNU grep instead by 1271 setting the WITH_GNU_GREP knob. 1272 127320100713: 1274 Due to the import of powerpc64 support, all existing powerpc kernel 1275 configuration files must be updated with a machine directive like this: 1276 machine powerpc powerpc 1277 1278 In addition, an updated config(8) is required to build powerpc kernels 1279 after this change. 1280 128120100713: 1282 A new version of ZFS (version 15) has been merged to -HEAD. 1283 This version uses a python library for the following subcommands: 1284 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1285 For full functionality of these commands the following port must 1286 be installed: sysutils/py-zfs 1287 128820100429: 1289 'vm_page's are now hashed by physical address to an array of mutexes. 1290 Currently this is only used to serialize access to hold_count. Over 1291 time the page queue mutex will be peeled away. This changes the size 1292 of pmap on every architecture. And requires all callers of vm_page_hold 1293 and vm_page_unhold to be updated. 1294 129520100402: 1296 WITH_CTF can now be specified in src.conf (not recommended, there 1297 are some problems with static executables), make.conf (would also 1298 affect ports which do not use GNU make and do not override the 1299 compile targets) or in the kernel config (via "makeoptions 1300 WITH_CTF=yes"). 1301 When WITH_CTF was specified there before this was silently ignored, 1302 so make sure that WITH_CTF is not used in places which could lead 1303 to unwanted behavior. 1304 130520100311: 1306 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1307 to allow 32-bit compatibility on non-x86 platforms. All kernel 1308 configurations on amd64 and ia64 platforms using these options must 1309 be modified accordingly. 1310 131120100113: 1312 The utmp user accounting database has been replaced with utmpx, 1313 the user accounting interface standardized by POSIX. 1314 Unfortunately the semantics of utmp and utmpx don't match, 1315 making it practically impossible to support both interfaces. 1316 The user accounting database is used by tools like finger(1), 1317 last(1), talk(1), w(1) and ac(8). 1318 1319 All applications in the base system use utmpx. This means only 1320 local binaries (e.g. from the ports tree) may still use these 1321 utmp database files. These applications must be rebuilt to make 1322 use of utmpx. 1323 1324 After the system has been upgraded, it is safe to remove the old 1325 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1326 assuming their contents is of no importance anymore. Old wtmp 1327 databases can only be used by last(1) and ac(8) after they have 1328 been converted to the new format using wtmpcvt(1). 1329 133020100108: 1331 Introduce the kernel thread "deadlock resolver" (which can be enabled 1332 via the DEADLKRES option, see NOTES for more details) and the 1333 sleepq_type() function for sleepqueues. 1334 133520091202: 1336 The rc.firewall and rc.firewall6 were unified, and 1337 rc.firewall6 and rc.d/ip6fw were removed. 1338 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1339 variables are obsoleted. Instead, the following new rc 1340 variables are added to rc.d/ipfw: 1341 1342 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1343 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1344 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1345 1346 The meanings correspond to the relevant IPv4 variables. 1347 134820091125: 1349 8.0-RELEASE. 1350 135120091113: 1352 The default terminal emulation for syscons(4) has been changed 1353 from cons25 to xterm on all platforms except pc98. This means 1354 that the /etc/ttys file needs to be updated to ensure correct 1355 operation of applications on the console. 1356 1357 The terminal emulation style can be toggled per window by using 1358 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1359 options can be used to change the compile-time default back to 1360 cons25. 1361 1362 To prevent graphical artifacts, make sure the TERM environment 1363 variable is set to match the terminal emulation that is being 1364 performed by syscons(4). 1365 136620091109: 1367 The layout of the structure ieee80211req_scan_result has changed. 1368 Applications that require wireless scan results (e.g. ifconfig(8)) 1369 from net80211 need to be recompiled. 1370 1371 Applications such as wpa_supplicant(8) may require a full world 1372 build without using NO_CLEAN in order to get synchronized with the 1373 new structure. 1374 137520091025: 1376 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1377 There's one kernel module for each firmware. Adding "device iwnfw" 1378 to the kernel configuration file means including all three firmware 1379 images inside the kernel. If you want to include just the one for 1380 your wireless card, use the devices iwn4965fw, iwn5000fw or 1381 iwn5150fw. 1382 138320090926: 1384 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1385 into rc.d/netif. The changes are the following: 1386 1387 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1388 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1389 Note that both variables need the "inet6" keyword at the head. 1390 1391 Do not set $ipv6_network_interfaces manually if you do not 1392 understand what you are doing. It is not needed in most cases. 1393 1394 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1395 they are obsolete. 1396 1397 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1398 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1399 1400 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1401 all configured interfaces have "inet6 accept_rtadv" in the 1402 $ifconfig_IF_ipv6. These are for backward compatibility. 1403 1404 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1405 functionality of interfaces with no corresponding 1406 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1407 and the default address selection policy of ip6addrctl(8) 1408 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1409 Note that if you want to configure IPv6 functionality on the 1410 disabled interfaces after boot, first you need to clear the flag by 1411 using ifconfig(8) like: 1412 1413 ifconfig em0 inet6 -ifdisabled 1414 1415 If YES, the default address selection policy is set as 1416 IPv6-preferred. 1417 1418 The default value of $ipv6_prefer is NO. 1419 1420 4. If your system need to receive Router Advertisement messages, 1421 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1422 scripts automatically invoke rtsol(8) when the interface becomes 1423 UP. The Router Advertisement messages are used for SLAAC 1424 (State-Less Address AutoConfiguration). 1425 142620090922: 1427 802.11s D3.03 support was committed. This is incompatible with the 1428 previous code, which was based on D3.0. 1429 143020090912: 1431 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1432 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1433 control whether accepting Router Advertisement messages or not. 1434 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1435 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1436 The ifconfig(8) utility now supports these flags. 1437 143820090910: 1439 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1440 mount(8) and -a option for df(1) to see them. 1441 144220090825: 1443 The old tunable hw.bus.devctl_disable has been superseded by 1444 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1445 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1446 is 1000. 1447 144820090813: 1449 Remove the option STOP_NMI. The default action is now to use NMI only 1450 for KDB via the newly introduced function stop_cpus_hard() and 1451 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1452 145320090803: 1454 The stable/8 branch created in subversion. This corresponds to the 1455 RELENG_8 branch in CVS. 1456 145720090719: 1458 Bump the shared library version numbers for all libraries that do not 1459 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1460 __FreeBSD_version to 800105. 1461 146220090714: 1463 Due to changes in the implementation of virtual network stack support, 1464 all network-related kernel modules must be recompiled. As this change 1465 breaks the ABI, bump __FreeBSD_version to 800104. 1466 146720090713: 1468 The TOE interface to the TCP syncache has been modified to remove 1469 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1470 The cxgb driver is the only TOE consumer affected by this change, and 1471 needs to be recompiled along with the kernel. As this change breaks 1472 the ABI, bump __FreeBSD_version to 800103. 1473 147420090712: 1475 Padding has been added to struct tcpcb, sackhint and tcpstat in 1476 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1477 maintaining the ABI. However, this change breaks the ABI, so bump 1478 __FreeBSD_version to 800102. User space tools that rely on the size of 1479 any of these structs (e.g. sockstat) need to be recompiled. 1480 148120090630: 1482 The NFS_LEGACYRPC option has been removed along with the old kernel 1483 RPC implementation that this option selected. Kernel configurations 1484 may need to be adjusted. 1485 148620090629: 1487 The network interface device nodes at /dev/net/<interface> have been 1488 removed. All ioctl operations can be performed the normal way using 1489 routing sockets. The kqueue functionality can generally be replaced 1490 with routing sockets. 1491 149220090628: 1493 The documentation from the FreeBSD Documentation Project (Handbook, 1494 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1495 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1496 149720090624: 1498 The ABI of various structures related to the SYSV IPC API have been 1499 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1500 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1501 800100. 1502 150320090622: 1504 Layout of struct vnet has changed as routing related variables were 1505 moved to their own Vimage module. Modules need to be recompiled. Bump 1506 __FreeBSD_version to 800099. 1507 150820090619: 1509 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1510 respectively. As long as no more than 16 groups per process are used, 1511 no changes should be visible. When more than 16 groups are used, old 1512 binaries may fail if they call getgroups() or getgrouplist() with 1513 statically sized storage. Recompiling will work around this, but 1514 applications should be modified to use dynamically allocated storage 1515 for group arrays as POSIX.1-2008 does not cap an implementation's 1516 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1517 1518 NFS and portalfs mounts may also be affected as the list of groups is 1519 truncated to 16. Users of NFS who use more than 16 groups, should 1520 take care that negative group permissions are not used on the exported 1521 file systems as they will not be reliable unless a GSSAPI based 1522 authentication method is used. 1523 152420090616: 1525 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1526 option compiles in the support for adaptive spinning for lockmgrs 1527 which want to enable it. The lockinit() function now accepts the flag 1528 LK_ADAPTIVE in order to make the lock object subject to adaptive 1529 spinning when both held in write and read mode. 1530 153120090613: 1532 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1533 changed. User applications that use this ioctl need to be rebuilt. 1534 153520090611: 1536 The layout of struct thread has changed. Kernel and modules need to 1537 be rebuilt. 1538 153920090608: 1540 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1541 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1542 154320090602: 1544 window(1) has been removed from the base system. It can now be 1545 installed from ports. The port is called misc/window. 1546 154720090601: 1548 The way we are storing and accessing `routing table' entries has 1549 changed. Programs reading the FIB, like netstat, need to be 1550 re-compiled. 1551 155220090601: 1553 A new netisr implementation has been added for FreeBSD 8. Network 1554 file system modules, such as igmp, ipdivert, and others, should be 1555 rebuilt. 1556 Bump __FreeBSD_version to 800096. 1557 155820090530: 1559 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1560 more valid. 1561 156220090530: 1563 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1564 Bump __FreeBSD_version to 800094. 1565 156620090529: 1567 Add mnt_xflag field to 'struct mount'. File system modules need to be 1568 rebuilt. 1569 Bump __FreeBSD_version to 800093. 1570 157120090528: 1572 The compiling option ADAPTIVE_SX has been retired while it has been 1573 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1574 The KPI for sx_init_flags() changes as accepting flags: 1575 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1576 been introduced in order to handle the reversed logic. 1577 Bump __FreeBSD_version to 800092. 1578 157920090527: 1580 Add support for hierarchical jails. Remove global securelevel. 1581 Bump __FreeBSD_version to 800091. 1582 158320090523: 1584 The layout of struct vnet_net has changed, therefore modules 1585 need to be rebuilt. 1586 Bump __FreeBSD_version to 800090. 1587 158820090523: 1589 The newly imported zic(8) produces a new format in the output. Please 1590 run tzsetup(8) to install the newly created data to /etc/localtime. 1591 159220090520: 1593 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1594 hw.usb.* and is now consistent again with previous releases. 1595 159620090520: 1597 802.11 monitor mode support was revised and driver api's were changed. 1598 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1599 of DLT_IEEE802_11. No user-visible data structures were changed but 1600 applications that use DLT_IEEE802_11 may require changes. 1601 Bump __FreeBSD_version to 800088. 1602 160320090430: 1604 The layout of the following structs has changed: sysctl_oid, 1605 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1606 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1607 panics may be experienced. World rebuild is required for 1608 correctly checking networking state from userland. 1609 Bump __FreeBSD_version to 800085. 1610 161120090429: 1612 MLDv2 and Source-Specific Multicast (SSM) have been merged 1613 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1614 The implementation of SSM within FreeBSD's IPv6 stack closely 1615 follows the IPv4 implementation. 1616 1617 For kernel developers: 1618 1619 * The most important changes are that the ip6_output() and 1620 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1621 and this lock has been downgraded to a non-recursive mutex. 1622 1623 * As with the changes to the IPv4 stack to support SSM, filtering 1624 of inbound multicast traffic must now be performed by transport 1625 protocols within the IPv6 stack. This does not apply to TCP and 1626 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1627 1628 * The KPIs used by IPv6 multicast are similar to those used by 1629 the IPv4 stack, with the following differences: 1630 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1631 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1632 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1633 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1634 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1635 for MLDv1 have an additional 'timer' argument which is used to 1636 jitter the initial membership report for the solicited-node 1637 multicast membership on-link. 1638 * This is not strictly needed for MLDv2, which already jitters 1639 its report transmissions. However, the 'timer' argument is 1640 preserved in case MLDv1 is active on the interface. 1641 1642 * The KAME linked-list based IPv6 membership implementation has 1643 been refactored to use a vector similar to that used by the IPv4 1644 stack. 1645 Code which maintains a list of its own multicast memberships 1646 internally, e.g. carp, has been updated to reflect the new 1647 semantics. 1648 1649 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1650 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1651 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1652 implementation constraint which needs to be addressed in HEAD. 1653 1654 For application developers: 1655 1656 * The changes are broadly similar to those made for the IPv4 1657 stack. 1658 1659 * The use of IPv4 and IPv6 multicast socket options on the same 1660 socket, using mapped addresses, HAS NOT been tested or supported. 1661 1662 * There are a number of issues with the implementation of various 1663 IPv6 multicast APIs which need to be resolved in the API surface 1664 before the implementation is fully compatible with KAME userland 1665 use, and these are mostly to do with interface index treatment. 1666 1667 * The literature available discusses the use of either the delta / ASM 1668 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1669 using setsourcefilter(3)/getsourcefilter(3). For more information 1670 please refer to RFC 3768, 'Socket Interface Extensions for 1671 Multicast Source Filters'. 1672 1673 * Applications which use the published RFC 3678 APIs should be fine. 1674 1675 For systems administrators: 1676 1677 * The mtest(8) utility has been refactored to support IPv6, in 1678 addition to IPv4. Interface addresses are no longer accepted 1679 as arguments, their names must be used instead. The utility 1680 will map the interface name to its first IPv4 address as 1681 returned by getifaddrs(3). 1682 1683 * The ifmcstat(8) utility has also been updated to print the MLDv2 1684 endpoint state and source filter lists via sysctl(3). 1685 1686 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1687 loopback of IPv6 multicast datagrams by default; it defaults to 1 1688 to preserve the existing behaviour. Disabling multicast loopback is 1689 recommended for optimal system performance. 1690 1691 * The IPv6 MROUTING code has been changed to examine this sysctl 1692 instead of attempting to perform a group lookup before looping 1693 back forwarded datagrams. 1694 1695 Bump __FreeBSD_version to 800084. 1696 169720090422: 1698 Implement low-level Bluetooth HCI API. 1699 Bump __FreeBSD_version to 800083. 1700 170120090419: 1702 The layout of struct malloc_type, used by modules to register new 1703 memory allocation types, has changed. Most modules will need to 1704 be rebuilt or panics may be experienced. 1705 Bump __FreeBSD_version to 800081. 1706 170720090415: 1708 Anticipate overflowing inp_flags - add inp_flags2. 1709 This changes most offsets in inpcb, so checking v4 connection 1710 state will require a world rebuild. 1711 Bump __FreeBSD_version to 800080. 1712 171320090415: 1714 Add an llentry to struct route and struct route_in6. Modules 1715 embedding a struct route will need to be recompiled. 1716 Bump __FreeBSD_version to 800079. 1717 171820090414: 1719 The size of rt_metrics_lite and by extension rtentry has changed. 1720 Networking administration apps will need to be recompiled. 1721 The route command now supports show as an alias for get, weighting 1722 of routes, sticky and nostick flags to alter the behavior of stateful 1723 load balancing. 1724 Bump __FreeBSD_version to 800078. 1725 172620090408: 1727 Do not use Giant for kbdmux(4) locking. This is wrong and 1728 apparently causing more problems than it solves. This will 1729 re-open the issue where interrupt handlers may race with 1730 kbdmux(4) in polling mode. Typical symptoms include (but 1731 not limited to) duplicated and/or missing characters when 1732 low level console functions (such as gets) are used while 1733 interrupts are enabled (for example geli password prompt, 1734 mountroot prompt etc.). Disabling kbdmux(4) may help. 1735 173620090407: 1737 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1738 kernel modules referencing any of the above need to be recompiled. 1739 Bump __FreeBSD_version to 800075. 1740 174120090320: 1742 GEOM_PART has become the default partition slicer for storage devices, 1743 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1744 introduces some changes: 1745 1746 MSDOS/EBR: the devices created from MSDOS extended partition entries 1747 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1748 to devices with offset-based names. fstabs may need to be modified. 1749 1750 BSD: the "geometry does not match label" warning is harmless in most 1751 cases but it points to problems in file system misalignment with 1752 disk geometry. The "c" partition is now implicit, covers the whole 1753 top-level drive and cannot be (mis)used by users. 1754 1755 General: Kernel dumps are now not allowed to be written to devices 1756 whose partition types indicate they are meant to be used for file 1757 systems (or, in case of MSDOS partitions, as something else than 1758 the "386BSD" type). 1759 1760 Most of these changes date approximately from 200812. 1761 176220090319: 1763 The uscanner(4) driver has been removed from the kernel. This follows 1764 Linux removing theirs in 2.6 and making libusb the default interface 1765 (supported by sane). 1766 176720090319: 1768 The multicast forwarding code has been cleaned up. netstat(1) 1769 only relies on KVM now for printing bandwidth upcall meters. 1770 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1771 ip6_mroute_mod respectively. The config(5) options for statically 1772 compiling this code remain the same, i.e. 'options MROUTING'. 1773 177420090315: 1775 Support for the IFF_NEEDSGIANT network interface flag has been 1776 removed, which means that non-MPSAFE network device drivers are no 1777 longer supported. In particular, if_ar, if_sr, and network device 1778 drivers from the old (legacy) USB stack can no longer be built or 1779 used. 1780 178120090313: 1782 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1783 a bunch of new language catalog files have also been added. 1784 This means that some common libc messages are now localized and 1785 they depend on the LC_MESSAGES environmental variable. 1786 178720090313: 1788 The k8temp(4) driver has been renamed to amdtemp(4) since 1789 support for Family 10 and Family 11 CPU families was added. 1790 179120090309: 1792 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1793 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1794 1795 For kernel developers, the most important changes are that the 1796 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1797 and this lock has been downgraded to a non-recursive mutex. 1798 1799 Transport protocols (UDP, Raw IP) are now responsible for filtering 1800 inbound multicast traffic according to group membership and source 1801 filters. The imo_multicast_filter() KPI exists for this purpose. 1802 Transports which do not use multicast (SCTP, TCP) already reject 1803 multicast by default. Forwarding and receive performance may improve 1804 as a mutex acquisition is no longer needed in the ip_input() 1805 low-level input path. in_addmulti() and in_delmulti() are shimmed 1806 to new KPIs which exist to support SSM in-kernel. 1807 1808 For application developers, it is recommended that loopback of 1809 multicast datagrams be disabled for best performance, as this 1810 will still cause the lock to be taken for each looped-back 1811 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1812 be tuned to 0 to disable loopback by default; it defaults to 1 1813 to preserve the existing behaviour. 1814 1815 For systems administrators, to obtain best performance with 1816 multicast reception and multiple groups, it is always recommended 1817 that a card with a suitably precise hash filter is used. Hash 1818 collisions will still result in the lock being taken within the 1819 transport protocol input path to check group membership. 1820 1821 If deploying FreeBSD in an environment with IGMP snooping switches, 1822 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1823 enabled; this forces 224.0.0.0/24 group membership to be announced 1824 via IGMP. 1825 1826 The size of 'struct igmpstat' has changed; netstat needs to be 1827 recompiled to reflect this. 1828 Bump __FreeBSD_version to 800070. 1829 183020090309: 1831 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1832 updated to use it. This requires a buildworld/installworld in order to 1833 update the library and dependencies (usbconfig, etc). Its advisable to 1834 rebuild all ports which uses libusb. More specific directions are given 1835 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1836 libusb are no longer required and can be removed. 1837 183820090302: 1839 A workaround is committed to allow the creation of System V shared 1840 memory segment of size > 2 GB on the 64-bit architectures. 1841 Due to a limitation of the existing ABI, the shm_segsz member 1842 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1843 wrong for large segments. Note that limits must be explicitly 1844 raised to allow such segments to be created. 1845 184620090301: 1847 The layout of struct ifnet has changed, requiring a rebuild of all 1848 network device driver modules. 1849 185020090227: 1851 The /dev handling for the new USB stack has changed, a 1852 buildworld/installworld is required for libusb20. 1853 185420090223: 1855 The new USB2 stack has now been permanently moved in and all kernel and 1856 module names reverted to their previous values (eg, usb, ehci, ohci, 1857 ums, ...). The old usb stack can be compiled in by prefixing the name 1858 with the letter 'o', the old usb modules have been removed. 1859 Updating entry 20090216 for xorg and 20090215 for libmap may still 1860 apply. 1861 186220090217: 1863 The rc.conf(5) option if_up_delay has been renamed to 1864 defaultroute_delay to better reflect its purpose. If you have 1865 customized this setting in /etc/rc.conf you need to update it to 1866 use the new name. 1867 186820090216: 1869 xorg 7.4 wants to configure its input devices via hald which does not 1870 yet work with USB2. If the keyboard/mouse does not work in xorg then 1871 add 1872 Option "AllowEmptyInput" "off" 1873 to your ServerLayout section. This will cause X to use the configured 1874 kbd and mouse sections from your xorg.conf. 1875 187620090215: 1877 The GENERIC kernels for all architectures now default to the new USB2 1878 stack. No kernel config options or code have been removed so if a 1879 problem arises please report it and optionally revert to the old USB 1880 stack. If you are loading USB kernel modules or have a custom kernel 1881 that includes GENERIC then ensure that usb names are also changed over, 1882 eg uftdi -> usb2_serial_ftdi. 1883 1884 Older programs linked against the ports libusb 0.1 need to be 1885 redirected to the new stack's libusb20. /etc/libmap.conf can 1886 be used for this: 1887 # Map old usb library to new one for usb2 stack 1888 libusb-0.1.so.8 libusb20.so.1 1889 189020090209: 1891 All USB ethernet devices now attach as interfaces under the name ueN 1892 (eg. ue0). This is to provide a predictable name as vendors often 1893 change usb chipsets in a product without notice. 1894 189520090203: 1896 The ichsmb(4) driver has been changed to require SMBus slave 1897 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1898 All of the other SMBus controller drivers require left-justified 1899 slave addresses, so this change makes all the drivers provide the 1900 same interface. 1901 190220090201: 1903 INET6 statistics (struct ip6stat) was updated. 1904 netstat(1) needs to be recompiled. 1905 190620090119: 1907 NTFS has been removed from GENERIC kernel on amd64 to match 1908 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1909 will load ntfs.ko module automatically when NTFS support is 1910 actually needed, unless ntfs.ko is not installed or security 1911 level prohibits loading kernel modules. If either is the case, 1912 "options NTFS" has to be added into kernel config. 1913 191420090115: 1915 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1916 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1917 800061. User space tools that rely on the size of struct tcpcb in 1918 tcp_var.h (e.g. sockstat) need to be recompiled. 1919 192020081225: 1921 ng_tty(4) module updated to match the new TTY subsystem. 1922 Due to API change, user-level applications must be updated. 1923 New API support added to mpd5 CVS and expected to be present 1924 in next mpd5.3 release. 1925 192620081219: 1927 With __FreeBSD_version 800060 the makefs tool is part of 1928 the base system (it was a port). 1929 193020081216: 1931 The afdata and ifnet locks have been changed from mutexes to 1932 rwlocks, network modules will need to be re-compiled. 1933 193420081214: 1935 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1936 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1937 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1938 architecture and 40 bytes on 64-bit architecture. The userland 1939 applications "arp" and "ndp" have been updated accordingly. 1940 The output from "netstat -r" shows only routing entries and 1941 none of the L2 information. 1942 194320081130: 1944 __FreeBSD_version 800057 marks the switchover from the 1945 binary ath hal to source code. Users must add the line: 1946 1947 options AH_SUPPORT_AR5416 1948 1949 to their kernel config files when specifying: 1950 1951 device ath_hal 1952 1953 The ath_hal module no longer exists; the code is now compiled 1954 together with the driver in the ath module. It is now 1955 possible to tailor chip support (i.e. reduce the set of chips 1956 and thereby the code size); consult ath_hal(4) for details. 1957 195820081121: 1959 __FreeBSD_version 800054 adds memory barriers to 1960 <machine/atomic.h>, new interfaces to ifnet to facilitate 1961 multiple hardware transmit queues for cards that support 1962 them, and a lock-less ring-buffer implementation to 1963 enable drivers to more efficiently manage queueing of 1964 packets. 1965 196620081117: 1967 A new version of ZFS (version 13) has been merged to -HEAD. 1968 This version has zpool attribute "listsnapshots" off by 1969 default, which means "zfs list" does not show snapshots, 1970 and is the same as Solaris behavior. 1971 197220081028: 1973 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1974 197520081009: 1976 The uhci, ohci, ehci and slhci USB Host controller drivers have 1977 been put into separate modules. If you load the usb module 1978 separately through loader.conf you will need to load the 1979 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1980 controller add the following to loader.conf: 1981 1982 uhci_load="YES" 1983 ehci_load="YES" 1984 198520081009: 1986 The ABI used by the PMC toolset has changed. Please keep 1987 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1988 sync. 1989 199020081009: 1991 atapci kernel module now includes only generic PCI ATA 1992 driver. AHCI driver moved to ataahci kernel module. 1993 All vendor-specific code moved into separate kernel modules: 1994 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1995 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1996 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1997 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1998 199920080820: 2000 The TTY subsystem of the kernel has been replaced by a new 2001 implementation, which provides better scalability and an 2002 improved driver model. Most common drivers have been migrated to 2003 the new TTY subsystem, while others have not. The following 2004 drivers have not yet been ported to the new TTY layer: 2005 2006 PCI/ISA: 2007 cy, digi, rc, rp, sio 2008 2009 USB: 2010 ubser, ucycom 2011 2012 Line disciplines: 2013 ng_h4, ng_tty, ppp, sl, snp 2014 2015 Adding these drivers to your kernel configuration file shall 2016 cause compilation to fail. 2017 201820080818: 2019 ntpd has been upgraded to 4.2.4p5. 2020 202120080801: 2022 OpenSSH has been upgraded to 5.1p1. 2023 2024 For many years, FreeBSD's version of OpenSSH preferred DSA 2025 over RSA for host and user authentication keys. With this 2026 upgrade, we've switched to the vendor's default of RSA over 2027 DSA. This may cause upgraded clients to warn about unknown 2028 host keys even for previously known hosts. Users should 2029 follow the usual procedure for verifying host keys before 2030 accepting the RSA key. 2031 2032 This can be circumvented by setting the "HostKeyAlgorithms" 2033 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2034 command line. 2035 2036 Please note that the sequence of keys offered for 2037 authentication has been changed as well. You may want to 2038 specify IdentityFile in a different order to revert this 2039 behavior. 2040 204120080713: 2042 The sio(4) driver has been removed from the i386 and amd64 2043 kernel configuration files. This means uart(4) is now the 2044 default serial port driver on those platforms as well. 2045 2046 To prevent collisions with the sio(4) driver, the uart(4) driver 2047 uses different names for its device nodes. This means the 2048 onboard serial port will now most likely be called "ttyu0" 2049 instead of "ttyd0". You may need to reconfigure applications to 2050 use the new device names. 2051 2052 When using the serial port as a boot console, be sure to update 2053 /boot/device.hints and /etc/ttys before booting the new kernel. 2054 If you forget to do so, you can still manually specify the hints 2055 at the loader prompt: 2056 2057 set hint.uart.0.at="isa" 2058 set hint.uart.0.port="0x3F8" 2059 set hint.uart.0.flags="0x10" 2060 set hint.uart.0.irq="4" 2061 boot -s 2062 206320080609: 2064 The gpt(8) utility has been removed. Use gpart(8) to partition 2065 disks instead. 2066 206720080603: 2068 The version that Linuxulator emulates was changed from 2.4.2 2069 to 2.6.16. If you experience any problems with Linux binaries 2070 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2071 if it fixes the problem contact emulation mailing list. 2072 207320080525: 2074 ISDN4BSD (I4B) was removed from the src tree. You may need to 2075 update a your kernel configuration and remove relevant entries. 2076 207720080509: 2078 I have checked in code to support multiple routing tables. 2079 See the man pages setfib(1) and setfib(2). 2080 This is a hopefully backwards compatible version, 2081 but to make use of it you need to compile your kernel 2082 with options ROUTETABLES=2 (or more up to 16). 2083 208420080420: 2085 The 802.11 wireless support was redone to enable multi-bss 2086 operation on devices that are capable. The underlying device 2087 is no longer used directly but instead wlanX devices are 2088 cloned with ifconfig. This requires changes to rc.conf files. 2089 For example, change: 2090 ifconfig_ath0="WPA DHCP" 2091 to 2092 wlans_ath0=wlan0 2093 ifconfig_wlan0="WPA DHCP" 2094 see rc.conf(5) for more details. In addition, mergemaster of 2095 /etc/rc.d is highly recommended. Simultaneous update of userland 2096 and kernel wouldn't hurt either. 2097 2098 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2099 modules were merged into the base wlan module. All references 2100 to these modules (e.g. in kernel config files) must be removed. 2101 210220080408: 2103 psm(4) has gained write(2) support in native operation level. 2104 Arbitrary commands can be written to /dev/psm%d and status can 2105 be read back from it. Therefore, an application is responsible 2106 for status validation and error recovery. It is a no-op in 2107 other operation levels. 2108 210920080312: 2110 Support for KSE threading has been removed from the kernel. To 2111 run legacy applications linked against KSE libmap.conf may 2112 be used. The following libmap.conf may be used to ensure 2113 compatibility with any prior release: 2114 2115 libpthread.so.1 libthr.so.1 2116 libpthread.so.2 libthr.so.2 2117 libkse.so.3 libthr.so.3 2118 211920080301: 2120 The layout of struct vmspace has changed. This affects libkvm 2121 and any executables that link against libkvm and use the 2122 kvm_getprocs() function. In particular, but not exclusively, 2123 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2124 The effects are minimal, but it's advisable to upgrade world 2125 nonetheless. 2126 212720080229: 2128 The latest em driver no longer has support in it for the 2129 82575 adapter, this is now moved to the igb driver. The 2130 split was done to make new features that are incompatible 2131 with older hardware easier to do. 2132 213320080220: 2134 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2135 likewise the kernel option is now GEOM_LINUX_LVM. 2136 213720080211: 2138 The default NFS mount mode has changed from UDP to TCP for 2139 increased reliability. If you rely on (insecurely) NFS 2140 mounting across a firewall you may need to update your 2141 firewall rules. 2142 214320080208: 2144 Belatedly note the addition of m_collapse for compacting 2145 mbuf chains. 2146 214720080126: 2148 The fts(3) structures have been changed to use adequate 2149 integer types for their members and so to be able to cope 2150 with huge file trees. The old fts(3) ABI is preserved 2151 through symbol versioning in libc, so third-party binaries 2152 using fts(3) should still work, although they will not take 2153 advantage of the extended types. At the same time, some 2154 third-party software might fail to build after this change 2155 due to unportable assumptions made in its source code about 2156 fts(3) structure members. Such software should be fixed 2157 by its vendor or, in the worst case, in the ports tree. 2158 FreeBSD_version 800015 marks this change for the unlikely 2159 case that a portable fix is impossible. 2160 216120080123: 2162 To upgrade to -current after this date, you must be running 2163 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2164 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2165 216620071128: 2167 The ADAPTIVE_GIANT kernel option has been retired because its 2168 functionality is the default now. 2169 217020071118: 2171 The AT keyboard emulation of sunkbd(4) has been turned on 2172 by default. In order to make the special symbols of the Sun 2173 keyboards driven by sunkbd(4) work under X these now have 2174 to be configured the same way as Sun USB keyboards driven 2175 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2176 2177 Option "XkbLayout" "us" 2178 Option "XkbRules" "xorg" 2179 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2180 218120071024: 2182 It has been decided that it is desirable to provide ABI 2183 backwards compatibility to the FreeBSD 4/5/6 versions of the 2184 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2185 broken with the introduction of PCI domain support (see the 2186 20070930 entry). Unfortunately, this required the ABI of 2187 PCIOCGETCONF to be broken again in order to be able to 2188 provide backwards compatibility to the old version of that 2189 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2190 again. As for prominent ports this affects neither pciutils 2191 nor xorg-server this time, the hal port needs to be rebuilt 2192 however. 2193 219420071020: 2195 The misnamed kthread_create() and friends have been renamed 2196 to kproc_create() etc. Many of the callers already 2197 used kproc_start().. 2198 I will return kthread_create() and friends in a while 2199 with implementations that actually create threads, not procs. 2200 Renaming corresponds with version 800002. 2201 220220071010: 2203 RELENG_7 branched. 2204 2205COMMON ITEMS: 2206 2207 General Notes 2208 ------------- 2209 Avoid using make -j when upgrading. While generally safe, there are 2210 sometimes problems using -j to upgrade. If your upgrade fails with 2211 -j, please try again without -j. From time to time in the past there 2212 have been problems using -j with buildworld and/or installworld. This 2213 is especially true when upgrading between "distant" versions (eg one 2214 that cross a major release boundary or several minor releases, or when 2215 several months have passed on the -current branch). 2216 2217 Sometimes, obscure build problems are the result of environment 2218 poisoning. This can happen because the make utility reads its 2219 environment when searching for values for global variables. To run 2220 your build attempts in an "environmental clean room", prefix all make 2221 commands with 'env -i '. See the env(1) manual page for more details. 2222 2223 When upgrading from one major version to another it is generally best 2224 to upgrade to the latest code in the currently installed branch first, 2225 then do an upgrade to the new branch. This is the best-tested upgrade 2226 path, and has the highest probability of being successful. Please try 2227 this approach before reporting problems with a major version upgrade. 2228 2229 When upgrading a live system, having a root shell around before 2230 installing anything can help undo problems. Not having a root shell 2231 around can lead to problems if pam has changed too much from your 2232 starting point to allow continued authentication after the upgrade. 2233 2234 ZFS notes 2235 --------- 2236 When upgrading the boot ZFS pool to a new version, always follow 2237 these two steps: 2238 2239 1.) recompile and reinstall the ZFS boot loader and boot block 2240 (this is part of "make buildworld" and "make installworld") 2241 2242 2.) update the ZFS boot block on your boot drive 2243 2244 The following example updates the ZFS boot block on the first 2245 partition (freebsd-boot) of a GPT partitioned drive ad0: 2246 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2247 2248 Non-boot pools do not need these updates. 2249 2250 To build a kernel 2251 ----------------- 2252 If you are updating from a prior version of FreeBSD (even one just 2253 a few days old), you should follow this procedure. It is the most 2254 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2255 2256 make kernel-toolchain 2257 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2258 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2259 2260 To test a kernel once 2261 --------------------- 2262 If you just want to boot a kernel once (because you are not sure 2263 if it works, or if you want to boot a known bad kernel to provide 2264 debugging information) run 2265 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2266 nextboot -k testkernel 2267 2268 To just build a kernel when you know that it won't mess you up 2269 -------------------------------------------------------------- 2270 This assumes you are already running a CURRENT system. Replace 2271 ${arch} with the architecture of your machine (e.g. "i386", 2272 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2273 2274 cd src/sys/${arch}/conf 2275 config KERNEL_NAME_HERE 2276 cd ../compile/KERNEL_NAME_HERE 2277 make depend 2278 make 2279 make install 2280 2281 If this fails, go to the "To build a kernel" section. 2282 2283 To rebuild everything and install it on the current system. 2284 ----------------------------------------------------------- 2285 # Note: sometimes if you are running current you gotta do more than 2286 # is listed here if you are upgrading from a really old current. 2287 2288 <make sure you have good level 0 dumps> 2289 make buildworld 2290 make kernel KERNCONF=YOUR_KERNEL_HERE 2291 [1] 2292 <reboot in single user> [3] 2293 mergemaster -p [5] 2294 make installworld 2295 mergemaster -i [4] 2296 make delete-old [6] 2297 <reboot> 2298 2299 To cross-install current onto a separate partition 2300 -------------------------------------------------- 2301 # In this approach we use a separate partition to hold 2302 # current's root, 'usr', and 'var' directories. A partition 2303 # holding "/", "/usr" and "/var" should be about 2GB in 2304 # size. 2305 2306 <make sure you have good level 0 dumps> 2307 <boot into -stable> 2308 make buildworld 2309 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2310 <maybe newfs current's root partition> 2311 <mount current's root partition on directory ${CURRENT_ROOT}> 2312 make installworld DESTDIR=${CURRENT_ROOT} 2313 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2314 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2315 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2316 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2317 <reboot into current> 2318 <do a "native" rebuild/install as described in the previous section> 2319 <maybe install compatibility libraries from ports/misc/compat*> 2320 <reboot> 2321 2322 2323 To upgrade in-place from stable to current 2324 ---------------------------------------------- 2325 <make sure you have good level 0 dumps> 2326 make buildworld [9] 2327 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2328 [1] 2329 <reboot in single user> [3] 2330 mergemaster -p [5] 2331 make installworld 2332 mergemaster -i [4] 2333 make delete-old [6] 2334 <reboot> 2335 2336 Make sure that you've read the UPDATING file to understand the 2337 tweaks to various things you need. At this point in the life 2338 cycle of current, things change often and you are on your own 2339 to cope. The defaults can also change, so please read ALL of 2340 the UPDATING entries. 2341 2342 Also, if you are tracking -current, you must be subscribed to 2343 freebsd-current@freebsd.org. Make sure that before you update 2344 your sources that you have read and understood all the recent 2345 messages there. If in doubt, please track -stable which has 2346 much fewer pitfalls. 2347 2348 [1] If you have third party modules, such as vmware, you 2349 should disable them at this point so they don't crash your 2350 system on reboot. 2351 2352 [3] From the bootblocks, boot -s, and then do 2353 fsck -p 2354 mount -u / 2355 mount -a 2356 cd src 2357 adjkerntz -i # if CMOS is wall time 2358 Also, when doing a major release upgrade, it is required that 2359 you boot into single user mode to do the installworld. 2360 2361 [4] Note: This step is non-optional. Failure to do this step 2362 can result in a significant reduction in the functionality of the 2363 system. Attempting to do it by hand is not recommended and those 2364 that pursue this avenue should read this file carefully, as well 2365 as the archives of freebsd-current and freebsd-hackers mailing lists 2366 for potential gotchas. The -U option is also useful to consider. 2367 See mergemaster(8) for more information. 2368 2369 [5] Usually this step is a noop. However, from time to time 2370 you may need to do this if you get unknown user in the following 2371 step. It never hurts to do it all the time. You may need to 2372 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2373 install) after the buildworld before this step if you last updated 2374 from current before 20130425 or from -stable before 20130430. 2375 2376 [6] This only deletes old files and directories. Old libraries 2377 can be deleted by "make delete-old-libs", but you have to make 2378 sure that no program is using those libraries anymore. 2379 2380 [8] In order to have a kernel that can run the 4.x binaries needed to 2381 do an installworld, you must include the COMPAT_FREEBSD4 option in 2382 your kernel. Failure to do so may leave you with a system that is 2383 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2384 required to run the 5.x binaries on more recent kernels. And so on 2385 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2386 2387 Make sure that you merge any new devices from GENERIC since the 2388 last time you updated your kernel config file. 2389 2390 [9] When checking out sources, you must include the -P flag to have 2391 cvs prune empty directories. 2392 2393 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2394 "?=" instead of the "=" assignment operator, so that buildworld can 2395 override the CPUTYPE if it needs to. 2396 2397 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2398 not on the command line, or in /etc/make.conf. buildworld will 2399 warn if it is improperly defined. 2400FORMAT: 2401 2402This file contains a list, in reverse chronological order, of major 2403breakages in tracking -current. It is not guaranteed to be a complete 2404list of such breakages, and only contains entries since October 10, 2007. 2405If you need to see UPDATING entries from before that date, you will need 2406to fetch an UPDATING file from an older FreeBSD release. 2407 2408Copyright information: 2409 2410Copyright 1998-2009 M.
