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 1920161010 p40 FreeBSD-SA-16:29.bspatch 20 FreeBSD-SA-16:30.portsnap 21 FreeBSD-SA-16:31.libarchive 22 23 Fix bspatch heap overflow vulnerability.

[EN-15:20] 136 13720151026: p23 FreeBSD-SA-15:25.ntp 138 139 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 140 141 The configuration file syntax has been changed, thus mergemaster 142 run is recommended. Now the "kod" parameter requires "limited" 143 parameter. If the ntp.conf is not updated, the ntpd will run 144 successfully, but with KoD disabled. 145 14620151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 147 Revised patch to address a regression that prevents NIS from working. 148 14920150929: p21 FreeBSD-SA-15:24.rpcbind 150 151 Fix rpcbind(8) remote denial of service.

[SA-15:02] 270 271 Fix SCTP stream reset vulnerability. [SA-15:03] 272 27320150114: p4 FreeBSD-SA-15:01.openssl 274 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 275 27620141223: p3 FreeBSD-SA-14:31.ntp 277 FreeBSD-EN-14:13.freebsd-update 278 279 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 280 Fix directory deletion issue in freebsd-update. [EN-14:13] 281 28220141217: p2 FreeBSD-SA-14:30.unbound 283 Fix unbound remote denial of service vulnerability. 284 28520141210: p1 FreeBSD-SA-14:27.stdio 286 FreeBSD-SA-14:28.file 287 288 Fix buffer overflow in stdio. [SA-14:27] 289 290 Fix multiple vulnerabilities in file(1) and libmagic(3). 291 [SA-14:28] 292 29320140904: 294 The ofwfb driver, used to provide a graphics console on PowerPC when 295 using vt(4), no longer allows mmap() of all of physical memory. This 296 will prevent Xorg on PowerPC with some ATI graphics cards from 297 initializing properly unless x11-servers/xorg-server is updated to 298 1.12.4_8 or newer. 299 30020140831: 301 The libatf-c and libatf-c++ major versions were downgraded to 0 and 302 1 respectively to match the upstream numbers. They were out of 303 sync because, when they were originally added to FreeBSD, the 304 upstream versions were not respected. These libraries are private 305 and not yet built by default, so renumbering them should be a 306 non-issue. However, unclean source trees will yield broken test 307 programs once the operator executes "make delete-old-libs" after a 308 "make installworld". 309 310 Additionally, the atf-sh binary was made private by moving it into 311 /usr/libexec/. Already-built shell test programs will keep the 312 path to the old binary so they will break after "make delete-old" 313 is run. 314 315 If you are using WITH_TESTS=yes (not the default), wipe the object 316 tree and rebuild from scratch to prevent spurious test failures. 317 This is only needed once: the misnumbered libraries and misplaced 318 binaries have been added to OptionalObsoleteFiles.inc so they will 319 be removed during a clean upgrade. 320 32120140814: 322 The ixgbe tunables now match their sysctl counterparts, for example: 323 hw.ixgbe.enable_aim => hw.ix.enable_aim 324 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 325 32620140801: 327 The NFSv4.1 server committed by r269398 changes the internal 328 function call interfaces used between the NFS and krpc modules. 329 As such, __FreeBSD_version was bumped. 330 33120140729: 332 The default unbound configuration has been modified to address 333 issues with reverse lookups on networks that use private 334 address ranges. If you use the local_unbound service, run 335 "service local_unbound setup" as root to regenerate your 336 configuration, then "service local_unbound reload" to load the 337 new configuration. 338 33920140717: 340 It is no longer necessary to include the dwarf version in your DEBUG 341 options in your kernel config file. The bug that required it to be 342 placed in the config file has bene fixed. DEBUG should now just 343 contain -g. The build system will automatically update things 344 to do the right thing. 345 34620140715: 347 Several ABI breaking changes were merged to CTL and new iSCSI code. 348 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 349 iscsictl need to be rebuilt to work with a new kernel. 350 35120140708: 352 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 353 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 354 which differs from the behaviour controlled by this knob.) 355 35620140608: 357 On i386 and amd64 systems, the onifconsole flag is now set by default 358 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 359 as a login TTY if it is set in the bootloader as an active kernel 360 console. No changes in behavior should result otherwise. To revert to 361 the previous behavior, set ttyu0 to "off" in /etc/ttys. 362 36320140512: 364 Clang and llvm have been upgraded to 3.4.1 release. 365 36620140321: 367 Clang and llvm have been upgraded to 3.4 release. 368 36920140306: 370 If a Makefile in a tests/ directory was auto-generating a Kyuafile 371 instead of providing an explicit one, this would prevent such 372 Makefile from providing its own Kyuafile in the future during 373 NO_CLEAN builds. This has been fixed in the Makefiles but manual 374 intervention is needed to clean an objdir if you use NO_CLEAN: 375 # find /usr/obj -name Kyuafile | xargs rm -f 376 37720140303: 378 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 379 capability mode support. Please note that enabling the feature in 380 kernel is still highly recommended. 381 38220140227: 383 OpenSSH is now built with sandbox support, and will use sandbox as 384 the default privilege separation method. This requires Capsicum 385 capability mode support in kernel. 386 38720140216: 388 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 389 been deprecated and will not be part of FreeBSD 11.0 and later 390 releases. If you use this driver, please consider switching to 391 the nfe(4) driver instead. 392 39320140120: 394 10.0-RELEASE. 395 39620131216: 397 The behavior of gss_pseudo_random() for the krb5 mechanism 398 has changed, for applications requesting a longer random string 399 than produced by the underlying enctype's pseudo-random() function. 400 In particular, the random string produced from a session key of 401 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 402 be different at the 17th octet and later, after this change. 403 The counter used in the PRF+ construction is now encoded as a 404 big-endian integer in accordance with RFC 4402. 405 __FreeBSD_version is bumped to 1000701. 406 40720131108: 408 The WITHOUT_ATF build knob has been removed and its functionality 409 has been subsumed into the more generic WITHOUT_TESTS. If you were 410 using the former to disable the build of the ATF libraries, you 411 should change your settings to use the latter. 412 41320131031: 414 The default version of mtree is nmtree which is obtained from 415 NetBSD. The output is generally the same, but may vary 416 slightly. If you found you need identical output adding 417 "-F freebsd9" to the command line should do the trick. For the 418 time being, the old mtree is available as fmtree. 419 42020131014: 421 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 422 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 423 1.1.4_8 and verify bsdyml not linked in, before running "make 424 delete-old-libs": 425 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 426 or 427 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 428 42920131010: 430 The rc.d/jail script has been updated to support jail(8) 431 configuration file. The "jail_<jname>_*" rc.conf(5) variables 432 for per-jail configuration are automatically converted to 433 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 434 This is transparently backward compatible. See below about some 435 incompatibilities and rc.conf(5) manual page for more details. 436 437 These variables are now deprecated in favor of jail(8) configuration 438 file. One can use "rc.d/jail config <jname>" command to generate 439 a jail(8) configuration file in /var/run/jail.<jname>.conf without 440 running the jail(8) utility. The default pathname of the 441 configuration file is /etc/jail.conf and can be specified by 442 using $jail_conf or $jail_<jname>_conf variables. 443 444 Please note that jail_devfs_ruleset accepts an integer at 445 this moment. Please consider to rewrite the ruleset name 446 with an integer. 447 44820130930: 449 BIND has been removed from the base system. If all you need 450 is a local resolver, simply enable and start the local_unbound 451 service instead. Otherwise, several versions of BIND are 452 available in the ports tree. The dns/bind99 port is one example. 453 454 With this change, nslookup(1) and dig(1) are no longer in the base 455 system. Users should instead use host(1) and drill(1) which are 456 in the base system. Alternatively, nslookup and dig can 457 be obtained by installing the dns/bind-tools port. 458 45920130916: 460 With the addition of unbound(8), a new unbound user is now 461 required during installworld. "mergemaster -p" can be used to 462 add the user prior to installworld, as documented in the handbook. 463 46420130911: 465 OpenSSH is now built with DNSSEC support, and will by default 466 silently trust signed SSHFP records. This can be controlled with 467 the VerifyHostKeyDNS client configuration setting. DNSSEC support 468 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 469 47020130906: 471 The GNU Compiler Collection and C++ standard library (libstdc++) 472 are no longer built by default on platforms where clang is the system 473 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 474 options in src.conf. 475 47620130905: 477 The PROCDESC kernel option is now part of the GENERIC kernel 478 configuration and is required for the rwhod(8) to work. 479 If you are using custom kernel configuration, you should include 480 'options PROCDESC'. 481 48220130905: 483 The API and ABI related to the Capsicum framework was modified 484 in backward incompatible way. The userland libraries and programs 485 have to be recompiled to work with the new kernel. This includes the 486 following libraries and programs, but the whole buildworld is 487 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 488 kdump, procstat, rwho, rwhod, uniq. 489 49020130903: 491 AES-NI intrinsic support has been added to gcc. The AES-NI module 492 has been updated to use this support. A new gcc is required to build 493 the aesni module on both i386 and amd64. 494 49520130821: 496 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 497 Thus "device padlock_rng" and "device rdrand_rng" should be 498 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 499 50020130813: 501 WITH_ICONV has been split into two feature sets. WITH_ICONV now 502 enables just the iconv* functionality and is now on by default. 503 WITH_LIBICONV_COMPAT enables the libiconv api and link time 504 compatability. Set WITHOUT_ICONV to build the old way. 505 If you have been using WITH_ICONV before, you will very likely 506 need to turn on WITH_LIBICONV_COMPAT. 507 50820130806: 509 INVARIANTS option now enables DEBUG for code with OpenSolaris and 510 Illumos origin, including ZFS. If you have INVARIANTS in your 511 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 512 explicitly. 513 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 514 locks if WITNESS option was set. Because that generated a lot of 515 witness(9) reports and all of them were believed to be false 516 positives, this is no longer done. New option OPENSOLARIS_WITNESS 517 can be used to achieve the previous behavior. 518 51920130806: 520 Timer values in IPv6 data structures now use time_uptime instead 521 of time_second. Although this is not a user-visible functional 522 change, userland utilities which directly use them---ndp(8), 523 rtadvd(8), and rtsold(8) in the base system---need to be updated 524 to r253970 or later. 525 52620130802: 527 find -delete can now delete the pathnames given as arguments, 528 instead of only files found below them or if the pathname did 529 not contain any slashes. Formerly, the following error message 530 would result: 531 532 find: -delete: <path>: relative path potentially not safe 533 534 Deleting the pathnames given as arguments can be prevented 535 without error messages using -mindepth 1 or by changing 536 directory and passing "." as argument to find. This works in the 537 old as well as the new version of find. 538 53920130726: 540 Behavior of devfs rules path matching has been changed. 541 Pattern is now always matched against fully qualified devfs 542 path and slash characters must be explicitly matched by 543 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 544 subdirectories must be reviewed. 545 54620130716: 547 The default ARM ABI has changed to the ARM EABI. The old ABI is 548 incompatible with the ARM EABI and all programs and modules will 549 need to be rebuilt to work with a new kernel. 550 551 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 552 553 NOTE: Support for the old ABI will be removed in the future and 554 users are advised to upgrade. 555 55620130709: 557 pkg_install has been disconnected from the build if you really need it 558 you should add WITH_PKGTOOLS in your src.conf(5). 559 56020130709: 561 Most of network statistics structures were changed to be able 562 keep 64-bits counters. Thus all tools, that work with networking 563 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 564 56520130629: 566 Fix targets that run multiple make's to use && rather than ; 567 so that subsequent steps depend on success of previous. 568 569 NOTE: if building 'universe' with -j* on stable/8 or stable/9 570 it would be better to start the build using bmake, to avoid 571 overloading the machine. 572 57320130618: 574 Fix a bug that allowed a tracing process (e.g. gdb) to write 575 to a memory-mapped file in the traced process's address space 576 even if neither the traced process nor the tracing process had 577 write access to that file. 578 57920130615: 580 CVS has been removed from the base system. An exact copy 581 of the code is available from the devel/cvs port. 582 58320130613: 584 Some people report the following error after the switch to bmake: 585 586 make: illegal option -- J 587 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 588 ... 589 *** [buildworld] Error code 2 590 591 this likely due to an old instance of make in 592 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 593 which src/Makefile will use that blindly, if it exists, so if 594 you see the above error: 595 596 rm -rf `make -V MAKEPATH` 597 598 should resolve it. 599 60020130516: 601 Use bmake by default. 602 Whereas before one could choose to build with bmake via 603 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 604 make. The goal is to remove these knobs for 10-RELEASE. 605 606 It is worth noting that bmake (like gmake) treats the command 607 line as the unit of failure, rather than statements within the 608 command line. Thus '(cd some/where && dosomething)' is safer 609 than 'cd some/where; dosomething'. The '()' allows consistent 610 behavior in parallel build. 611 61220130429: 613 Fix a bug that allows NFS clients to issue READDIR on files. 614 61520130426: 616 The WITHOUT_IDEA option has been removed because 617 the IDEA patent expired. 618 61920130426: 620 The sysctl which controls TRIM support under ZFS has been renamed 621 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 622 enabled by default. 623 62420130425: 625 The mergemaster command now uses the default MAKEOBJDIRPREFIX 626 rather than creating it's own in the temporary directory in 627 order allow access to bootstrapped versions of tools such as 628 install and mtree. When upgrading from version of FreeBSD where 629 the install command does not support -l, you will need to 630 install a new mergemaster command if mergemaster -p is required. 631 This can be accomplished with the command (cd src/usr.sbin/mergemaster 632 && make install). 633 63420130404: 635 Legacy ATA stack, disabled and replaced by new CAM-based one since 636 FreeBSD 9.0, completely removed from the sources. Kernel modules 637 atadisk and atapi*, user-level tools atacontrol and burncd are 638 removed. Kernel option `options ATA_CAM` is now permanently enabled 639 and removed. 640 64120130319: 642 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 643 and socketpair(2). Software, in particular Kerberos, may 644 automatically detect and use these during building. The resulting 645 binaries will not work on older kernels. 646 64720130308: 648 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 649 information, see the respective 20130304 entry). 650 65120130304: 652 Recent commits to callout(9) changed the size of struct callout, 653 so the KBI is probably heavily disturbed. Also, some functions 654 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 655 by macros. Every kernel module using it won't load, so rebuild 656 is requested. 657 658 The ctl device has been re-enabled in GENERIC for i386 and amd64, 659 but does not initialize by default (because of the new CTL_DISABLE 660 option) to save memory. To re-enable it, remove the CTL_DISABLE 661 option from the kernel config file or set kern.cam.ctl.disable=0 662 in /boot/loader.conf. 663 66420130301: 665 The ctl device has been disabled in GENERIC for i386 and amd64. 666 This was done due to the extra memory being allocated at system 667 initialisation time by the ctl driver which was only used if 668 a CAM target device was created. This makes a FreeBSD system 669 unusable on 128MB or less of RAM. 670 67120130208: 672 A new compression method (lz4) has been merged to -HEAD. Please 673 refer to zpool-features(7) for more information. 674 675 Please refer to the "ZFS notes" section of this file for information 676 on upgrading boot ZFS pools. 677 67820130129: 679 A BSD-licensed patch(1) variant has been added and is installed 680 as bsdpatch, being the GNU version the default patch. 681 To inverse the logic and use the BSD-licensed one as default, 682 while having the GNU version installed as gnupatch, rebuild 683 and install world with the WITH_BSD_PATCH knob set. 684 68520130121: 686 Due to the use of the new -l option to install(1) during build 687 and install, you must take care not to directly set the INSTALL 688 make variable in your /etc/make.conf, /etc/src.conf, or on the 689 command line. If you wish to use the -C flag for all installs 690 you may be able to add INSTALL+=-C to /etc/make.conf or 691 /etc/src.conf. 692 69320130118: 694 The install(1) option -M has changed meaning and now takes an 695 argument that is a file or path to append logs to. In the 696 unlikely event that -M was the last option on the command line 697 and the command line contained at least two files and a target 698 directory the first file will have logs appended to it. The -M 699 option served little practical purpose in the last decade so its 700 use is expected to be extremely rare. 701 70220121223: 703 After switching to Clang as the default compiler some users of ZFS 704 on i386 systems started to experience stack overflow kernel panics. 705 Please consider using 'options KSTACK_PAGES=4' in such configurations. 706 70720121222: 708 GEOM_LABEL now mangles label names read from file system metadata. 709 Mangling affect labels containing spaces, non-printable characters, 710 '%' or '"'. Device names in /etc/fstab and other places may need to 711 be updated. 712 71320121217: 714 By default, only the 10 most recent kernel dumps will be saved. To 715 restore the previous behaviour (no limit on the number of kernel dumps 716 stored in the dump directory) add the following line to /etc/rc.conf: 717 718 savecore_flags="" 719 72020121201: 721 With the addition of auditdistd(8), a new auditdistd user is now 722 required during installworld. "mergemaster -p" can be used to 723 add the user prior to installworld, as documented in the handbook. 724 72520121117: 726 The sin6_scope_id member variable in struct sockaddr_in6 is now 727 filled by the kernel before passing the structure to the userland via 728 sysctl or routing socket. This means the KAME-specific embedded scope 729 id in sin6_addr.s6_addr[2] is always cleared in userland application. 730 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 731 __FreeBSD_version is bumped to 1000025. 732 73320121105: 734 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 735 This means that the world and kernel will be compiled with clang 736 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 737 and /usr/bin/cpp. To disable this behavior and revert to building 738 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 739 of current may need to bootstrap WITHOUT_CLANG first if the clang 740 build fails (its compatibility window doesn't extend to the 9 stable 741 branch point). 742 74320121102: 744 The IPFIREWALL_FORWARD kernel option has been removed. Its 745 functionality now turned on by default. 746 74720121023: 748 The ZERO_COPY_SOCKET kernel option has been removed and 749 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 750 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 751 mechanism which is not safe and may result in kernel crashes. 752 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 753 driver supports disposeable external page sized mbuf storage. 754 Proper replacements for both zero-copy mechanisms are under 755 consideration and will eventually lead to complete removal 756 of the two kernel options. 757 75820121023: 759 The IPv4 network stack has been converted to network byte 760 order. The following modules need to be recompiled together 761 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 762 pf(4), ipfw(4), ng_ipfw(4), stf(4). 763 76420121022: 765 Support for non-MPSAFE filesystems was removed from VFS. The 766 VFS_VERSION was bumped, all filesystem modules shall be 767 recompiled. 768 76920121018: 770 All the non-MPSAFE filesystems have been disconnected from 771 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 772 portalfs, smbfs, xfs. 773 77420121016: 775 The interface cloning API and ABI has changed. The following 776 modules need to be recompiled together with kernel: 777 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 778 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 779 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 780 78120121015: 782 The sdhci driver was split in two parts: sdhci (generic SD Host 783 Controller logic) and sdhci_pci (actual hardware driver). 784 No kernel config modifications are required, but if you 785 load sdhc as a module you must switch to sdhci_pci instead. 786 78720121014: 788 Import the FUSE kernel and userland support into base system. 789 79020121013: 791 The GNU sort(1) program has been removed since the BSD-licensed 792 sort(1) has been the default for quite some time and no serious 793 problems have been reported. The corresponding WITH_GNU_SORT 794 knob has also gone. 795 79620121006: 797 The pfil(9) API/ABI for AF_INET family has been changed. Packet 798 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 799 with new kernel. 800 80120121001: 802 The net80211(4) ABI has been changed to allow for improved driver 803 PS-POLL and power-save support. All wireless drivers need to be 804 recompiled to work with the new kernel. 805 80620120913: 807 The random(4) support for the VIA hardware random number 808 generator (`PADLOCK') is no longer enabled unconditionally. 809 Add the padlock_rng device in the custom kernel config if 810 needed. The GENERIC kernels on i386 and amd64 do include the 811 device, so the change only affects the custom kernel 812 configurations. 813 81420120908: 815 The pf(4) packet filter ABI has been changed. pfctl(8) and 816 snmp_pf module need to be recompiled to work with new kernel. 817 81820120828: 819 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 820 to -HEAD. Pools that have empty_bpobj in active state can not be 821 imported read-write with ZFS implementations that do not support 822 this feature. For more information read the zpool-features(5) 823 manual page. 824 82520120727: 826 The sparc64 ZFS loader has been changed to no longer try to auto- 827 detect ZFS providers based on diskN aliases but now requires these 828 to be explicitly listed in the OFW boot-device environment variable. 829 83020120712: 831 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 832 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 833 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 834 83520120712: 836 The following sysctls and tunables have been renamed for consistency 837 with other variables: 838 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 839 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 840 84120120628: 842 The sort utility has been replaced with BSD sort. For now, GNU sort 843 is also available as "gnusort" or the default can be set back to 844 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 845 installed as "bsdsort". 846 84720120611: 848 A new version of ZFS (pool version 5000) has been merged to -HEAD. 849 Starting with this version the old system of ZFS pool versioning 850 is superseded by "feature flags". This concept enables forward 851 compatibility against certain future changes in functionality of ZFS 852 pools. The first read-only compatible "feature flag" for ZFS pools 853 is named "com.delphix:async_destroy". For more information 854 read the new zpool-features(5) manual page. 855 Please refer to the "ZFS notes" section of this file for information 856 on upgrading boot ZFS pools. 857 85820120417: 859 The malloc(3) implementation embedded in libc now uses sources imported 860 as contrib/jemalloc. The most disruptive API change is to 861 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 862 delete it prior to installworld, and optionally re-create it using the 863 new format after rebooting. See malloc.conf(5) for details 864 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 865 NAMESPACE section). 866 86720120328: 868 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 869 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 870 now spelled mips. This is to aid compatibility with third-party 871 software that expects this naming scheme in uname(3). Little-endian 872 settings are unchanged. If you are updating a big-endian mips64 machine 873 from before this change, you may need to set MACHINE_ARCH=mips64 in 874 your environment before the new build system will recognize your machine. 875 87620120306: 877 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 878 platforms. 879 88020120229: 881 Now unix domain sockets behave "as expected" on nullfs(5). Previously 882 nullfs(5) did not pass through all behaviours to the underlying layer, 883 as a result if we bound to a socket on the lower layer we could connect 884 only to the lower path; if we bound to the upper layer we could connect 885 only to the upper path. The new behavior is one can connect to both the 886 lower and the upper paths regardless what layer path one binds to. 887 88820120211: 889 The getifaddrs upgrade path broken with 20111215 has been restored. 890 If you have upgraded in between 20111215 and 20120209 you need to 891 recompile libc again with your kernel. You still need to recompile 892 world to be able to configure CARP but this restriction already 893 comes from 20111215. 894 89520120114: 896 The set_rcvar() function has been removed from /etc/rc.subr. All 897 base and ports rc.d scripts have been updated, so if you have a 898 port installed with a script in /usr/local/etc/rc.d you can either 899 hand-edit the rcvar= line, or reinstall the port. 900 901 An easy way to handle the mass-update of /etc/rc.d: 902 rm /etc/rc.d/* && mergemaster -i 903 90420120109: 905 panic(9) now stops other CPUs in the SMP systems, disables interrupts 906 on the current CPU and prevents other threads from running. 907 This behavior can be reverted using the kern.stop_scheduler_on_panic 908 tunable/sysctl. 909 The new behavior can be incompatible with kern.sync_on_panic. 910 91120111215: 912 The carp(4) facility has been changed significantly. Configuration 913 of the CARP protocol via ifconfig(8) has changed, as well as format 914 of CARP events submitted to devd(8) has changed. See manual pages 915 for more information. The arpbalance feature of carp(4) is currently 916 not supported anymore. 917 918 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 919 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 920 need to be recompiled. 921 92220111122: 923 The acpi_wmi(4) status device /dev/wmistat has been renamed to 924 /dev/wmistat0. 925 92620111108: 927 The option VFS_ALLOW_NONMPSAFE option has been added in order to 928 explicitely support non-MPSAFE filesystems. 929 It is on by default for all supported platform at this present 930 time. 931 93220111101: 933 The broken amd(4) driver has been replaced with esp(4) in the amd64, 934 i386 and pc98 GENERIC kernel configuration files. 935 93620110930: 937 sysinstall has been removed 938 93920110923: 940 The stable/9 branch created in subversion. This corresponds to the 941 RELENG_9 branch in CVS. 942 94320110913: 944 This commit modifies vfs_register() so that it uses a hash 945 calculation to set vfc_typenum, which is enabled by default. 946 The first time a system is booted after this change, the 947 vfc_typenum values will change for all file systems. The 948 main effect of this is a change to the NFS server file handles 949 for file systems that use vfc_typenum in their fsid, such as ZFS. 950 It will, however, prevent vfc_typenum from changing when file 951 systems are loaded in a different order for subsequent reboots. 952 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 953 until you are ready to remount all NFS clients after a reboot. 954 95520110828: 956 Bump the shared library version numbers for libraries that 957 do not use symbol versioning, have changed the ABI compared 958 to stable/8 and which shared library version was not bumped. 959 Done as part of 9.0-RELEASE cycle. 960 96120110815: 962 During the merge of Capsicum features, the fget(9) KPI was modified. 963 This may require the rebuilding of out-of-tree device drivers -- 964 issues have been reported specifically with the nVidia device driver. 965 __FreeBSD_version is bumped to 900041. 966 967 Also, there is a period between 20110811 and 20110814 where the 968 special devices /dev/{stdin,stdout,stderr} did not work correctly. 969 Building world from a kernel during that window may not work. 970 97120110628: 972 The packet filter (pf) code has been updated to OpenBSD 4.5. 973 You need to update userland tools to be in sync with kernel. 974 This update breaks backward compatibility with earlier pfsync(4) 975 versions. Care must be taken when updating redundant firewall setups. 976 97720110608: 978 The following sysctls and tunables are retired on x86 platforms: 979 machdep.hlt_cpus 980 machdep.hlt_logical_cpus 981 The following sysctl is retired: 982 machdep.hyperthreading_allowed 983 The sysctls were supposed to provide a way to dynamically offline and 984 online selected CPUs on x86 platforms, but the implementation has not 985 been reliable especially with SCHED_ULE scheduler. 986 machdep.hyperthreading_allowed tunable is still available to ignore 987 hyperthreading CPUs at OS level. 988 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 989 where X is an APIC ID of a CPU. Be advised, though, that disabling 990 CPUs in non-uniform fashion will result in non-uniform topology and 991 may lead to sub-optimal system performance with SCHED_ULE, which is 992 a default scheduler. 993 99420110607: 995 cpumask_t type is retired and cpuset_t is used in order to describe 996 a mask of CPUs. 997 99820110531: 999 Changes to ifconfig(8) for dynamic address family detection mandate 1000 that you are running a kernel of 20110525 or later. Make sure to 1001 follow the update procedure to boot a new kernel before installing 1002 world. 1003 100420110513: 1005 Support for sun4v architecture is officially dropped 1006 100720110503: 1008 Several KPI breaking changes have been committed to the mii(4) layer, 1009 the PHY drivers and consequently some Ethernet drivers using mii(4). 1010 This means that miibus.ko and the modules of the affected Ethernet 1011 drivers need to be recompiled. 1012 1013 Note to kernel developers: Given that the OUI bit reversion problem 1014 was fixed as part of these changes all mii(4) commits related to OUIs, 1015 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1016 handling, no longer can be merged verbatim to stable/8 and previous 1017 branches. 1018 101920110430: 1020 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1021 into their kernel configurations along with 'device pci'. 1022 102320110427: 1024 The default NFS client is now the new NFS client, so fstype "newnfs" 1025 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1026 Although mounts via fstype "nfs" will usually work without userland 1027 changes, it is recommended that the mount(8) and mount_nfs(8) 1028 commands be rebuilt from sources and that a link to mount_nfs called 1029 mount_oldnfs be created. The new client is compiled into the 1030 kernel with "options NFSCL" and this is needed for diskless root 1031 file systems. The GENERIC kernel configs have been changed to use 1032 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1033 To use the regular/old client, you can "mount -t oldnfs ...". For 1034 a diskless root file system, you must also include a line like: 1035 1036 vfs.root.mountfrom="oldnfs:" 1037 1038 in the boot/loader.conf on the root fs on the NFS server to make 1039 a diskless root fs use the old client. 1040 104120110424: 1042 The GENERIC kernels for all architectures now default to the new 1043 CAM-based ATA stack. It means that all legacy ATA drivers were 1044 removed and replaced by respective CAM drivers. If you are using 1045 ATA device names in /etc/fstab or other places, make sure to update 1046 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1047 where 'Y's are the sequential numbers starting from zero for each type 1048 in order of detection, unless configured otherwise with tunables, 1049 see cam(4)). There will be symbolic links created in /dev/ to map 1050 old adX devices to the respective adaY. They should provide basic 1051 compatibility for file systems mounting in most cases, but they do 1052 not support old user-level APIs and do not have respective providers 1053 in GEOM. Consider using updated management tools with new device names. 1054 1055 It is possible to load devices ahci, ata, siis and mvs as modules, 1056 but option ATA_CAM should remain in kernel configuration to make ata 1057 module work as CAM driver supporting legacy ATA controllers. Device ata 1058 still can be used in modular fashion (atacore + ...). Modules atadisk 1059 and atapi* are not used and won't affect operation in ATA_CAM mode. 1060 Note that to use CAM-based ATA kernel should include CAM devices 1061 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1062 them are parts of the cam module. 1063 1064 ataraid(4) functionality is now supported by the RAID GEOM class. 1065 To use it you can load geom_raid kernel module and use graid(8) tool 1066 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1067 1068 No kernel config options or code have been removed, so if a problem 1069 arises, please report it and optionally revert to the old ATA stack. 1070 In order to do it you can remove from the kernel config: 1071 options ATA_CAM 1072 device ahci 1073 device mvs 1074 device siis 1075 , and instead add back: 1076 device atadisk # ATA disk drives 1077 device ataraid # ATA RAID drives 1078 device atapicd # ATAPI CDROM drives 1079 device atapifd # ATAPI floppy drives 1080 device atapist # ATAPI tape drives 1081 108220110423: 1083 The default NFS server has been changed to the new server, which 1084 was referred to as the experimental server. If you need to switch 1085 back to the old NFS server, you must now put the "-o" option on 1086 both the mountd and nfsd commands. This can be done using the 1087 mountd_flags and nfs_server_flags rc.conf variables until an 1088 update to the rc scripts is committed, which is coming soon. 1089 109020110418: 1091 The GNU Objective-C runtime library (libobjc), and other Objective-C 1092 related components have been removed from the base system. If you 1093 require an Objective-C library, please use one of the available ports. 1094 109520110331: 1096 ath(4) has been split into bus- and device- modules. if_ath contains 1097 the HAL, the TX rate control and the network device code. if_ath_pci 1098 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1099 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1100 in order to use ath on everything else. 1101 1102 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1103 need to load if_ath and if_ath_pci for ath(4) operation. 1104 110520110314: 1106 As part of the replacement of sysinstall, the process of building 1107 release media has changed significantly. For details, please re-read 1108 release(7), which has been updated to reflect the new build process. 1109 111020110218: 1111 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1112 is the last available version under GPLv2. It brings a number of new 1113 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1114 4.1 and SSE 4.2), better support for powerpc64, a number of new 1115 directives, and lots of other small improvements. See the ChangeLog 1116 file in contrib/binutils for the full details. 1117 111820110218: 1119 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1120 compliant, and will now use half of hash for authentication. 1121 This will break interoperability with all stacks (including all 1122 actual FreeBSD versions) who implement 1123 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1124 authentication). 1125 The only workaround with such peers is to use another HMAC 1126 algorithm for IPsec ("phase 2") authentication. 1127 112820110207: 1129 Remove the uio_yield prototype and symbol. This function has 1130 been misnamed since it was introduced and should not be 1131 globally exposed with this name. The equivalent functionality 1132 is now available using kern_yield(curthread->td_user_pri). 1133 The function remains undocumented. 1134 113520110112: 1136 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1137 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1138 for scalar sysctls is defined but disabled. Code that needs 1139 UQUAD to pass the type checking that must compile on older 1140 systems where the define is not present can check against 1141 __FreeBSD_version >= 900030. 1142 1143 The system dialog(1) has been replaced with a new version previously 1144 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1145 with the previous version, but the libdialog associated with it has 1146 a largely incompatible API. As such, the original version of libdialog 1147 will be kept temporarily as libodialog, until its base system consumers 1148 are replaced or updated. Bump __FreeBSD_version to 900030. 1149 115020110103: 1151 If you are trying to run make universe on a -stable system, and you get 1152 the following warning: 1153 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1154 unknown. config(8) likely too old." 1155 or something similar to it, then you must upgrade your -stable system 1156 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1157 stable/8) or build the config from the latest stable/8 branch and 1158 install it on your system. 1159 1160 Prior to this date, building a current universe on 8-stable system from 1161 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1162 error in the first kernel build phase. A new config on those old 1163 systems will fix that problem for older versions of -current. 1164 116520101228: 1166 The TCP stack has been modified to allow Khelp modules to interact with 1167 it via helper hook points and store per-connection data in the TCP 1168 control block. Bump __FreeBSD_version to 900029. User space tools that 1169 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1170 be recompiled. 1171 117220101114: 1173 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1174 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1175 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1176 to take advantage of it instead of using custom implementations. This 1177 means that these drivers now no longer unconditionally advertise 1178 support for flow control but only do so if flow control is a selected 1179 media option. This was implemented in the generic support that way in 1180 order to allow flow control to be switched on and off via ifconfig(8) 1181 with the PHY specific default to typically off in order to protect 1182 from unwanted effects. Consequently, if you used flow control with 1183 one of the above mentioned drivers you now need to explicitly enable 1184 it, for example via: 1185 ifconfig bge0 media auto mediaopt flowcontrol 1186 1187 Along with the above mentioned changes generic support for setting 1188 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1189 e1000phy(4) as well as ip1000phy(4) have been converted to take 1190 advantage of it. This means that these drivers now no longer take the 1191 link0 parameter for selecting master mode but the master media option 1192 has to be used instead, for example like in the following: 1193 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1194 1195 Selection of master mode now is also available with all other PHY 1196 drivers supporting 1000baseT. 1197 119820101111: 1199 The TCP stack has received a significant update to add support for 1200 modularised congestion control and generally improve the clarity of 1201 congestion control decisions. Bump __FreeBSD_version to 900025. User 1202 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1203 sockstat) need to be recompiled. 1204 120520101002: 1206 The man(1) utility has been replaced by a new version that no longer 1207 uses /etc/manpath.config. Please consult man.conf(5) for how to 1208 migrate local entries to the new format. 1209 121020100928: 1211 The copyright strings printed by login(1) and sshd(8) at the time of a 1212 new connection have been removed to follow other operating systems and 1213 upstream sshd. 1214 121520100915: 1216 A workaround for a fixed ld bug has been removed in kernel code, 1217 so make sure that your system ld is built from sources after 1218 revision 210245 from 2010-07-19 (r211583 if building head kernel 1219 on stable/8, r211584 for stable/7; both from 2010-08-21). 1220 A symptom of incorrect ld version is different addresses for 1221 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1222 122320100913: 1224 The $ipv6_prefer variable in rc.conf(5) has been split into 1225 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1226 1227 The $ip6addrctl_policy is a variable to choose a pre-defined 1228 address selection policy set by ip6addrctl(8). A value 1229 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1230 default is "AUTO". 1231 1232 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1233 flag (see an entry of 20090926) is set on an interface with no 1234 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1235 security reason. If you want IPv6 link-local address on all 1236 interfaces by default, set this to "YES". 1237 1238 The old ipv6_prefer="YES" is equivalent to 1239 ipv6_activate_all_interfaces="YES" and 1240 ip6addrctl_policy="ipv6_prefer". 1241 124220100913: 1243 DTrace has grown support for userland tracing. Due to this, DTrace is 1244 now i386 and amd64 only. 1245 dtruss(1) is now installed by default on those systems and a new 1246 kernel module is needed for userland tracing: fasttrap. 1247 No changes to your kernel config file are necessary to enable 1248 userland tracing, but you might consider adding 'STRIP=' and 1249 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1250 to have informative userland stack traces in DTrace (ustack). 1251 125220100725: 1253 The acpi_aiboost(4) driver has been removed in favor of the new 1254 aibs(4) driver. You should update your kernel configuration file. 1255 125620100722: 1257 BSD grep has been imported to the base system and it is built by 1258 default. It is completely BSD licensed, highly GNU-compatible, uses 1259 less memory than its GNU counterpart and has a small codebase. 1260 However, it is slower than its GNU counterpart, which is mostly 1261 noticeable for larger searches, for smaller ones it is measurable 1262 but not significant. The reason is complex, the most important factor 1263 is that we lack a modern and efficient regex library and GNU 1264 overcomes this by optimizing the searches internally. Future work 1265 on improving the regex performance is planned, for the meantime, 1266 users that need better performance, can build GNU grep instead by 1267 setting the WITH_GNU_GREP knob. 1268 126920100713: 1270 Due to the import of powerpc64 support, all existing powerpc kernel 1271 configuration files must be updated with a machine directive like this: 1272 machine powerpc powerpc 1273 1274 In addition, an updated config(8) is required to build powerpc kernels 1275 after this change. 1276 127720100713: 1278 A new version of ZFS (version 15) has been merged to -HEAD. 1279 This version uses a python library for the following subcommands: 1280 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1281 For full functionality of these commands the following port must 1282 be installed: sysutils/py-zfs 1283 128420100429: 1285 'vm_page's are now hashed by physical address to an array of mutexes. 1286 Currently this is only used to serialize access to hold_count. Over 1287 time the page queue mutex will be peeled away. This changes the size 1288 of pmap on every architecture. And requires all callers of vm_page_hold 1289 and vm_page_unhold to be updated. 1290 129120100402: 1292 WITH_CTF can now be specified in src.conf (not recommended, there 1293 are some problems with static executables), make.conf (would also 1294 affect ports which do not use GNU make and do not override the 1295 compile targets) or in the kernel config (via "makeoptions 1296 WITH_CTF=yes"). 1297 When WITH_CTF was specified there before this was silently ignored, 1298 so make sure that WITH_CTF is not used in places which could lead 1299 to unwanted behavior. 1300 130120100311: 1302 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1303 to allow 32-bit compatibility on non-x86 platforms. All kernel 1304 configurations on amd64 and ia64 platforms using these options must 1305 be modified accordingly. 1306 130720100113: 1308 The utmp user accounting database has been replaced with utmpx, 1309 the user accounting interface standardized by POSIX. 1310 Unfortunately the semantics of utmp and utmpx don't match, 1311 making it practically impossible to support both interfaces. 1312 The user accounting database is used by tools like finger(1), 1313 last(1), talk(1), w(1) and ac(8). 1314 1315 All applications in the base system use utmpx. This means only 1316 local binaries (e.g. from the ports tree) may still use these 1317 utmp database files. These applications must be rebuilt to make 1318 use of utmpx. 1319 1320 After the system has been upgraded, it is safe to remove the old 1321 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1322 assuming their contents is of no importance anymore. Old wtmp 1323 databases can only be used by last(1) and ac(8) after they have 1324 been converted to the new format using wtmpcvt(1). 1325 132620100108: 1327 Introduce the kernel thread "deadlock resolver" (which can be enabled 1328 via the DEADLKRES option, see NOTES for more details) and the 1329 sleepq_type() function for sleepqueues. 1330 133120091202: 1332 The rc.firewall and rc.firewall6 were unified, and 1333 rc.firewall6 and rc.d/ip6fw were removed. 1334 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1335 variables are obsoleted. Instead, the following new rc 1336 variables are added to rc.d/ipfw: 1337 1338 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1339 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1340 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1341 1342 The meanings correspond to the relevant IPv4 variables. 1343 134420091125: 1345 8.0-RELEASE. 1346 134720091113: 1348 The default terminal emulation for syscons(4) has been changed 1349 from cons25 to xterm on all platforms except pc98. This means 1350 that the /etc/ttys file needs to be updated to ensure correct 1351 operation of applications on the console. 1352 1353 The terminal emulation style can be toggled per window by using 1354 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1355 options can be used to change the compile-time default back to 1356 cons25. 1357 1358 To prevent graphical artifacts, make sure the TERM environment 1359 variable is set to match the terminal emulation that is being 1360 performed by syscons(4). 1361 136220091109: 1363 The layout of the structure ieee80211req_scan_result has changed. 1364 Applications that require wireless scan results (e.g. ifconfig(8)) 1365 from net80211 need to be recompiled. 1366 1367 Applications such as wpa_supplicant(8) may require a full world 1368 build without using NO_CLEAN in order to get synchronized with the 1369 new structure. 1370 137120091025: 1372 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1373 There's one kernel module for each firmware. Adding "device iwnfw" 1374 to the kernel configuration file means including all three firmware 1375 images inside the kernel. If you want to include just the one for 1376 your wireless card, use the devices iwn4965fw, iwn5000fw or 1377 iwn5150fw. 1378 137920090926: 1380 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1381 into rc.d/netif. The changes are the following: 1382 1383 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1384 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1385 Note that both variables need the "inet6" keyword at the head. 1386 1387 Do not set $ipv6_network_interfaces manually if you do not 1388 understand what you are doing. It is not needed in most cases. 1389 1390 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1391 they are obsolete. 1392 1393 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1394 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1395 1396 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1397 all configured interfaces have "inet6 accept_rtadv" in the 1398 $ifconfig_IF_ipv6. These are for backward compatibility. 1399 1400 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1401 functionality of interfaces with no corresponding 1402 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1403 and the default address selection policy of ip6addrctl(8) 1404 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1405 Note that if you want to configure IPv6 functionality on the 1406 disabled interfaces after boot, first you need to clear the flag by 1407 using ifconfig(8) like: 1408 1409 ifconfig em0 inet6 -ifdisabled 1410 1411 If YES, the default address selection policy is set as 1412 IPv6-preferred. 1413 1414 The default value of $ipv6_prefer is NO. 1415 1416 4. If your system need to receive Router Advertisement messages, 1417 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1418 scripts automatically invoke rtsol(8) when the interface becomes 1419 UP. The Router Advertisement messages are used for SLAAC 1420 (State-Less Address AutoConfiguration). 1421 142220090922: 1423 802.11s D3.03 support was committed. This is incompatible with the 1424 previous code, which was based on D3.0. 1425 142620090912: 1427 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1428 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1429 control whether accepting Router Advertisement messages or not. 1430 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1431 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1432 The ifconfig(8) utility now supports these flags. 1433 143420090910: 1435 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1436 mount(8) and -a option for df(1) to see them. 1437 143820090825: 1439 The old tunable hw.bus.devctl_disable has been superseded by 1440 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1441 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1442 is 1000. 1443 144420090813: 1445 Remove the option STOP_NMI. The default action is now to use NMI only 1446 for KDB via the newly introduced function stop_cpus_hard() and 1447 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1448 144920090803: 1450 The stable/8 branch created in subversion. This corresponds to the 1451 RELENG_8 branch in CVS. 1452 145320090719: 1454 Bump the shared library version numbers for all libraries that do not 1455 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1456 __FreeBSD_version to 800105. 1457 145820090714: 1459 Due to changes in the implementation of virtual network stack support, 1460 all network-related kernel modules must be recompiled. As this change 1461 breaks the ABI, bump __FreeBSD_version to 800104. 1462 146320090713: 1464 The TOE interface to the TCP syncache has been modified to remove 1465 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1466 The cxgb driver is the only TOE consumer affected by this change, and 1467 needs to be recompiled along with the kernel. As this change breaks 1468 the ABI, bump __FreeBSD_version to 800103. 1469 147020090712: 1471 Padding has been added to struct tcpcb, sackhint and tcpstat in 1472 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1473 maintaining the ABI. However, this change breaks the ABI, so bump 1474 __FreeBSD_version to 800102. User space tools that rely on the size of 1475 any of these structs (e.g. sockstat) need to be recompiled. 1476 147720090630: 1478 The NFS_LEGACYRPC option has been removed along with the old kernel 1479 RPC implementation that this option selected. Kernel configurations 1480 may need to be adjusted. 1481 148220090629: 1483 The network interface device nodes at /dev/net/<interface> have been 1484 removed. All ioctl operations can be performed the normal way using 1485 routing sockets. The kqueue functionality can generally be replaced 1486 with routing sockets. 1487 148820090628: 1489 The documentation from the FreeBSD Documentation Project (Handbook, 1490 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1491 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1492 149320090624: 1494 The ABI of various structures related to the SYSV IPC API have been 1495 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1496 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1497 800100. 1498 149920090622: 1500 Layout of struct vnet has changed as routing related variables were 1501 moved to their own Vimage module. Modules need to be recompiled. Bump 1502 __FreeBSD_version to 800099. 1503 150420090619: 1505 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1506 respectively. As long as no more than 16 groups per process are used, 1507 no changes should be visible. When more than 16 groups are used, old 1508 binaries may fail if they call getgroups() or getgrouplist() with 1509 statically sized storage. Recompiling will work around this, but 1510 applications should be modified to use dynamically allocated storage 1511 for group arrays as POSIX.1-2008 does not cap an implementation's 1512 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1513 1514 NFS and portalfs mounts may also be affected as the list of groups is 1515 truncated to 16. Users of NFS who use more than 16 groups, should 1516 take care that negative group permissions are not used on the exported 1517 file systems as they will not be reliable unless a GSSAPI based 1518 authentication method is used. 1519 152020090616: 1521 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1522 option compiles in the support for adaptive spinning for lockmgrs 1523 which want to enable it. The lockinit() function now accepts the flag 1524 LK_ADAPTIVE in order to make the lock object subject to adaptive 1525 spinning when both held in write and read mode. 1526 152720090613: 1528 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1529 changed. User applications that use this ioctl need to be rebuilt. 1530 153120090611: 1532 The layout of struct thread has changed. Kernel and modules need to 1533 be rebuilt. 1534 153520090608: 1536 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1537 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1538 153920090602: 1540 window(1) has been removed from the base system. It can now be 1541 installed from ports. The port is called misc/window. 1542 154320090601: 1544 The way we are storing and accessing `routing table' entries has 1545 changed. Programs reading the FIB, like netstat, need to be 1546 re-compiled. 1547 154820090601: 1549 A new netisr implementation has been added for FreeBSD 8. Network 1550 file system modules, such as igmp, ipdivert, and others, should be 1551 rebuilt. 1552 Bump __FreeBSD_version to 800096. 1553 155420090530: 1555 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1556 more valid. 1557 155820090530: 1559 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1560 Bump __FreeBSD_version to 800094. 1561 156220090529: 1563 Add mnt_xflag field to 'struct mount'. File system modules need to be 1564 rebuilt. 1565 Bump __FreeBSD_version to 800093. 1566 156720090528: 1568 The compiling option ADAPTIVE_SX has been retired while it has been 1569 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1570 The KPI for sx_init_flags() changes as accepting flags: 1571 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1572 been introduced in order to handle the reversed logic. 1573 Bump __FreeBSD_version to 800092. 1574 157520090527: 1576 Add support for hierarchical jails. Remove global securelevel. 1577 Bump __FreeBSD_version to 800091. 1578 157920090523: 1580 The layout of struct vnet_net has changed, therefore modules 1581 need to be rebuilt. 1582 Bump __FreeBSD_version to 800090. 1583 158420090523: 1585 The newly imported zic(8) produces a new format in the output. Please 1586 run tzsetup(8) to install the newly created data to /etc/localtime. 1587 158820090520: 1589 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1590 hw.usb.* and is now consistent again with previous releases. 1591 159220090520: 1593 802.11 monitor mode support was revised and driver api's were changed. 1594 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1595 of DLT_IEEE802_11. No user-visible data structures were changed but 1596 applications that use DLT_IEEE802_11 may require changes. 1597 Bump __FreeBSD_version to 800088. 1598 159920090430: 1600 The layout of the following structs has changed: sysctl_oid, 1601 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1602 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1603 panics may be experienced. World rebuild is required for 1604 correctly checking networking state from userland. 1605 Bump __FreeBSD_version to 800085. 1606 160720090429: 1608 MLDv2 and Source-Specific Multicast (SSM) have been merged 1609 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1610 The implementation of SSM within FreeBSD's IPv6 stack closely 1611 follows the IPv4 implementation. 1612 1613 For kernel developers: 1614 1615 * The most important changes are that the ip6_output() and 1616 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1617 and this lock has been downgraded to a non-recursive mutex. 1618 1619 * As with the changes to the IPv4 stack to support SSM, filtering 1620 of inbound multicast traffic must now be performed by transport 1621 protocols within the IPv6 stack. This does not apply to TCP and 1622 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1623 1624 * The KPIs used by IPv6 multicast are similar to those used by 1625 the IPv4 stack, with the following differences: 1626 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1627 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1628 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1629 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1630 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1631 for MLDv1 have an additional 'timer' argument which is used to 1632 jitter the initial membership report for the solicited-node 1633 multicast membership on-link. 1634 * This is not strictly needed for MLDv2, which already jitters 1635 its report transmissions. However, the 'timer' argument is 1636 preserved in case MLDv1 is active on the interface. 1637 1638 * The KAME linked-list based IPv6 membership implementation has 1639 been refactored to use a vector similar to that used by the IPv4 1640 stack. 1641 Code which maintains a list of its own multicast memberships 1642 internally, e.g. carp, has been updated to reflect the new 1643 semantics. 1644 1645 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1646 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1647 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1648 implementation constraint which needs to be addressed in HEAD. 1649 1650 For application developers: 1651 1652 * The changes are broadly similar to those made for the IPv4 1653 stack. 1654 1655 * The use of IPv4 and IPv6 multicast socket options on the same 1656 socket, using mapped addresses, HAS NOT been tested or supported. 1657 1658 * There are a number of issues with the implementation of various 1659 IPv6 multicast APIs which need to be resolved in the API surface 1660 before the implementation is fully compatible with KAME userland 1661 use, and these are mostly to do with interface index treatment. 1662 1663 * The literature available discusses the use of either the delta / ASM 1664 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1665 using setsourcefilter(3)/getsourcefilter(3). For more information 1666 please refer to RFC 3768, 'Socket Interface Extensions for 1667 Multicast Source Filters'. 1668 1669 * Applications which use the published RFC 3678 APIs should be fine. 1670 1671 For systems administrators: 1672 1673 * The mtest(8) utility has been refactored to support IPv6, in 1674 addition to IPv4. Interface addresses are no longer accepted 1675 as arguments, their names must be used instead. The utility 1676 will map the interface name to its first IPv4 address as 1677 returned by getifaddrs(3). 1678 1679 * The ifmcstat(8) utility has also been updated to print the MLDv2 1680 endpoint state and source filter lists via sysctl(3). 1681 1682 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1683 loopback of IPv6 multicast datagrams by default; it defaults to 1 1684 to preserve the existing behaviour. Disabling multicast loopback is 1685 recommended for optimal system performance. 1686 1687 * The IPv6 MROUTING code has been changed to examine this sysctl 1688 instead of attempting to perform a group lookup before looping 1689 back forwarded datagrams. 1690 1691 Bump __FreeBSD_version to 800084. 1692 169320090422: 1694 Implement low-level Bluetooth HCI API. 1695 Bump __FreeBSD_version to 800083. 1696 169720090419: 1698 The layout of struct malloc_type, used by modules to register new 1699 memory allocation types, has changed. Most modules will need to 1700 be rebuilt or panics may be experienced. 1701 Bump __FreeBSD_version to 800081. 1702 170320090415: 1704 Anticipate overflowing inp_flags - add inp_flags2. 1705 This changes most offsets in inpcb, so checking v4 connection 1706 state will require a world rebuild. 1707 Bump __FreeBSD_version to 800080. 1708 170920090415: 1710 Add an llentry to struct route and struct route_in6. Modules 1711 embedding a struct route will need to be recompiled. 1712 Bump __FreeBSD_version to 800079. 1713 171420090414: 1715 The size of rt_metrics_lite and by extension rtentry has changed. 1716 Networking administration apps will need to be recompiled. 1717 The route command now supports show as an alias for get, weighting 1718 of routes, sticky and nostick flags to alter the behavior of stateful 1719 load balancing. 1720 Bump __FreeBSD_version to 800078. 1721 172220090408: 1723 Do not use Giant for kbdmux(4) locking. This is wrong and 1724 apparently causing more problems than it solves. This will 1725 re-open the issue where interrupt handlers may race with 1726 kbdmux(4) in polling mode. Typical symptoms include (but 1727 not limited to) duplicated and/or missing characters when 1728 low level console functions (such as gets) are used while 1729 interrupts are enabled (for example geli password prompt, 1730 mountroot prompt etc.). Disabling kbdmux(4) may help. 1731 173220090407: 1733 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1734 kernel modules referencing any of the above need to be recompiled. 1735 Bump __FreeBSD_version to 800075. 1736 173720090320: 1738 GEOM_PART has become the default partition slicer for storage devices, 1739 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1740 introduces some changes: 1741 1742 MSDOS/EBR: the devices created from MSDOS extended partition entries 1743 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1744 to devices with offset-based names. fstabs may need to be modified. 1745 1746 BSD: the "geometry does not match label" warning is harmless in most 1747 cases but it points to problems in file system misalignment with 1748 disk geometry. The "c" partition is now implicit, covers the whole 1749 top-level drive and cannot be (mis)used by users. 1750 1751 General: Kernel dumps are now not allowed to be written to devices 1752 whose partition types indicate they are meant to be used for file 1753 systems (or, in case of MSDOS partitions, as something else than 1754 the "386BSD" type). 1755 1756 Most of these changes date approximately from 200812. 1757 175820090319: 1759 The uscanner(4) driver has been removed from the kernel. This follows 1760 Linux removing theirs in 2.6 and making libusb the default interface 1761 (supported by sane). 1762 176320090319: 1764 The multicast forwarding code has been cleaned up. netstat(1) 1765 only relies on KVM now for printing bandwidth upcall meters. 1766 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1767 ip6_mroute_mod respectively. The config(5) options for statically 1768 compiling this code remain the same, i.e. 'options MROUTING'. 1769 177020090315: 1771 Support for the IFF_NEEDSGIANT network interface flag has been 1772 removed, which means that non-MPSAFE network device drivers are no 1773 longer supported. In particular, if_ar, if_sr, and network device 1774 drivers from the old (legacy) USB stack can no longer be built or 1775 used. 1776 177720090313: 1778 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1779 a bunch of new language catalog files have also been added. 1780 This means that some common libc messages are now localized and 1781 they depend on the LC_MESSAGES environmental variable. 1782 178320090313: 1784 The k8temp(4) driver has been renamed to amdtemp(4) since 1785 support for Family 10 and Family 11 CPU families was added. 1786 178720090309: 1788 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1789 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1790 1791 For kernel developers, the most important changes are that the 1792 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1793 and this lock has been downgraded to a non-recursive mutex. 1794 1795 Transport protocols (UDP, Raw IP) are now responsible for filtering 1796 inbound multicast traffic according to group membership and source 1797 filters. The imo_multicast_filter() KPI exists for this purpose. 1798 Transports which do not use multicast (SCTP, TCP) already reject 1799 multicast by default. Forwarding and receive performance may improve 1800 as a mutex acquisition is no longer needed in the ip_input() 1801 low-level input path. in_addmulti() and in_delmulti() are shimmed 1802 to new KPIs which exist to support SSM in-kernel. 1803 1804 For application developers, it is recommended that loopback of 1805 multicast datagrams be disabled for best performance, as this 1806 will still cause the lock to be taken for each looped-back 1807 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1808 be tuned to 0 to disable loopback by default; it defaults to 1 1809 to preserve the existing behaviour. 1810 1811 For systems administrators, to obtain best performance with 1812 multicast reception and multiple groups, it is always recommended 1813 that a card with a suitably precise hash filter is used. Hash 1814 collisions will still result in the lock being taken within the 1815 transport protocol input path to check group membership. 1816 1817 If deploying FreeBSD in an environment with IGMP snooping switches, 1818 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1819 enabled; this forces 224.0.0.0/24 group membership to be announced 1820 via IGMP. 1821 1822 The size of 'struct igmpstat' has changed; netstat needs to be 1823 recompiled to reflect this. 1824 Bump __FreeBSD_version to 800070. 1825 182620090309: 1827 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1828 updated to use it. This requires a buildworld/installworld in order to 1829 update the library and dependencies (usbconfig, etc). Its advisable to 1830 rebuild all ports which uses libusb. More specific directions are given 1831 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1832 libusb are no longer required and can be removed. 1833 183420090302: 1835 A workaround is committed to allow the creation of System V shared 1836 memory segment of size > 2 GB on the 64-bit architectures. 1837 Due to a limitation of the existing ABI, the shm_segsz member 1838 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1839 wrong for large segments. Note that limits must be explicitly 1840 raised to allow such segments to be created. 1841 184220090301: 1843 The layout of struct ifnet has changed, requiring a rebuild of all 1844 network device driver modules. 1845 184620090227: 1847 The /dev handling for the new USB stack has changed, a 1848 buildworld/installworld is required for libusb20. 1849 185020090223: 1851 The new USB2 stack has now been permanently moved in and all kernel and 1852 module names reverted to their previous values (eg, usb, ehci, ohci, 1853 ums, ...). The old usb stack can be compiled in by prefixing the name 1854 with the letter 'o', the old usb modules have been removed. 1855 Updating entry 20090216 for xorg and 20090215 for libmap may still 1856 apply. 1857 185820090217: 1859 The rc.conf(5) option if_up_delay has been renamed to 1860 defaultroute_delay to better reflect its purpose. If you have 1861 customized this setting in /etc/rc.conf you need to update it to 1862 use the new name. 1863 186420090216: 1865 xorg 7.4 wants to configure its input devices via hald which does not 1866 yet work with USB2. If the keyboard/mouse does not work in xorg then 1867 add 1868 Option "AllowEmptyInput" "off" 1869 to your ServerLayout section. This will cause X to use the configured 1870 kbd and mouse sections from your xorg.conf. 1871 187220090215: 1873 The GENERIC kernels for all architectures now default to the new USB2 1874 stack. No kernel config options or code have been removed so if a 1875 problem arises please report it and optionally revert to the old USB 1876 stack. If you are loading USB kernel modules or have a custom kernel 1877 that includes GENERIC then ensure that usb names are also changed over, 1878 eg uftdi -> usb2_serial_ftdi. 1879 1880 Older programs linked against the ports libusb 0.1 need to be 1881 redirected to the new stack's libusb20. /etc/libmap.conf can 1882 be used for this: 1883 # Map old usb library to new one for usb2 stack 1884 libusb-0.1.so.8 libusb20.so.1 1885 188620090209: 1887 All USB ethernet devices now attach as interfaces under the name ueN 1888 (eg. ue0). This is to provide a predictable name as vendors often 1889 change usb chipsets in a product without notice. 1890 189120090203: 1892 The ichsmb(4) driver has been changed to require SMBus slave 1893 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1894 All of the other SMBus controller drivers require left-justified 1895 slave addresses, so this change makes all the drivers provide the 1896 same interface. 1897 189820090201: 1899 INET6 statistics (struct ip6stat) was updated. 1900 netstat(1) needs to be recompiled. 1901 190220090119: 1903 NTFS has been removed from GENERIC kernel on amd64 to match 1904 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1905 will load ntfs.ko module automatically when NTFS support is 1906 actually needed, unless ntfs.ko is not installed or security 1907 level prohibits loading kernel modules. If either is the case, 1908 "options NTFS" has to be added into kernel config. 1909 191020090115: 1911 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1912 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1913 800061. User space tools that rely on the size of struct tcpcb in 1914 tcp_var.h (e.g. sockstat) need to be recompiled. 1915 191620081225: 1917 ng_tty(4) module updated to match the new TTY subsystem. 1918 Due to API change, user-level applications must be updated. 1919 New API support added to mpd5 CVS and expected to be present 1920 in next mpd5.3 release. 1921 192220081219: 1923 With __FreeBSD_version 800060 the makefs tool is part of 1924 the base system (it was a port). 1925 192620081216: 1927 The afdata and ifnet locks have been changed from mutexes to 1928 rwlocks, network modules will need to be re-compiled. 1929 193020081214: 1931 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1932 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1933 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1934 architecture and 40 bytes on 64-bit architecture. The userland 1935 applications "arp" and "ndp" have been updated accordingly. 1936 The output from "netstat -r" shows only routing entries and 1937 none of the L2 information. 1938 193920081130: 1940 __FreeBSD_version 800057 marks the switchover from the 1941 binary ath hal to source code. Users must add the line: 1942 1943 options AH_SUPPORT_AR5416 1944 1945 to their kernel config files when specifying: 1946 1947 device ath_hal 1948 1949 The ath_hal module no longer exists; the code is now compiled 1950 together with the driver in the ath module. It is now 1951 possible to tailor chip support (i.e. reduce the set of chips 1952 and thereby the code size); consult ath_hal(4) for details. 1953 195420081121: 1955 __FreeBSD_version 800054 adds memory barriers to 1956 <machine/atomic.h>, new interfaces to ifnet to facilitate 1957 multiple hardware transmit queues for cards that support 1958 them, and a lock-less ring-buffer implementation to 1959 enable drivers to more efficiently manage queueing of 1960 packets. 1961 196220081117: 1963 A new version of ZFS (version 13) has been merged to -HEAD. 1964 This version has zpool attribute "listsnapshots" off by 1965 default, which means "zfs list" does not show snapshots, 1966 and is the same as Solaris behavior. 1967 196820081028: 1969 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1970 197120081009: 1972 The uhci, ohci, ehci and slhci USB Host controller drivers have 1973 been put into separate modules. If you load the usb module 1974 separately through loader.conf you will need to load the 1975 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1976 controller add the following to loader.conf: 1977 1978 uhci_load="YES" 1979 ehci_load="YES" 1980 198120081009: 1982 The ABI used by the PMC toolset has changed. Please keep 1983 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1984 sync. 1985 198620081009: 1987 atapci kernel module now includes only generic PCI ATA 1988 driver. AHCI driver moved to ataahci kernel module. 1989 All vendor-specific code moved into separate kernel modules: 1990 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1991 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1992 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1993 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1994 199520080820: 1996 The TTY subsystem of the kernel has been replaced by a new 1997 implementation, which provides better scalability and an 1998 improved driver model. Most common drivers have been migrated to 1999 the new TTY subsystem, while others have not. The following 2000 drivers have not yet been ported to the new TTY layer: 2001 2002 PCI/ISA: 2003 cy, digi, rc, rp, sio 2004 2005 USB: 2006 ubser, ucycom 2007 2008 Line disciplines: 2009 ng_h4, ng_tty, ppp, sl, snp 2010 2011 Adding these drivers to your kernel configuration file shall 2012 cause compilation to fail. 2013 201420080818: 2015 ntpd has been upgraded to 4.2.4p5. 2016 201720080801: 2018 OpenSSH has been upgraded to 5.1p1. 2019 2020 For many years, FreeBSD's version of OpenSSH preferred DSA 2021 over RSA for host and user authentication keys. With this 2022 upgrade, we've switched to the vendor's default of RSA over 2023 DSA. This may cause upgraded clients to warn about unknown 2024 host keys even for previously known hosts. Users should 2025 follow the usual procedure for verifying host keys before 2026 accepting the RSA key. 2027 2028 This can be circumvented by setting the "HostKeyAlgorithms" 2029 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2030 command line. 2031 2032 Please note that the sequence of keys offered for 2033 authentication has been changed as well. You may want to 2034 specify IdentityFile in a different order to revert this 2035 behavior. 2036 203720080713: 2038 The sio(4) driver has been removed from the i386 and amd64 2039 kernel configuration files. This means uart(4) is now the 2040 default serial port driver on those platforms as well. 2041 2042 To prevent collisions with the sio(4) driver, the uart(4) driver 2043 uses different names for its device nodes. This means the 2044 onboard serial port will now most likely be called "ttyu0" 2045 instead of "ttyd0". You may need to reconfigure applications to 2046 use the new device names. 2047 2048 When using the serial port as a boot console, be sure to update 2049 /boot/device.hints and /etc/ttys before booting the new kernel. 2050 If you forget to do so, you can still manually specify the hints 2051 at the loader prompt: 2052 2053 set hint.uart.0.at="isa" 2054 set hint.uart.0.port="0x3F8" 2055 set hint.uart.0.flags="0x10" 2056 set hint.uart.0.irq="4" 2057 boot -s 2058 205920080609: 2060 The gpt(8) utility has been removed. Use gpart(8) to partition 2061 disks instead. 2062 206320080603: 2064 The version that Linuxulator emulates was changed from 2.4.2 2065 to 2.6.16. If you experience any problems with Linux binaries 2066 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2067 if it fixes the problem contact emulation mailing list. 2068 206920080525: 2070 ISDN4BSD (I4B) was removed from the src tree. You may need to 2071 update a your kernel configuration and remove relevant entries. 2072 207320080509: 2074 I have checked in code to support multiple routing tables. 2075 See the man pages setfib(1) and setfib(2). 2076 This is a hopefully backwards compatible version, 2077 but to make use of it you need to compile your kernel 2078 with options ROUTETABLES=2 (or more up to 16). 2079 208020080420: 2081 The 802.11 wireless support was redone to enable multi-bss 2082 operation on devices that are capable. The underlying device 2083 is no longer used directly but instead wlanX devices are 2084 cloned with ifconfig. This requires changes to rc.conf files. 2085 For example, change: 2086 ifconfig_ath0="WPA DHCP" 2087 to 2088 wlans_ath0=wlan0 2089 ifconfig_wlan0="WPA DHCP" 2090 see rc.conf(5) for more details. In addition, mergemaster of 2091 /etc/rc.d is highly recommended. Simultaneous update of userland 2092 and kernel wouldn't hurt either. 2093 2094 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2095 modules were merged into the base wlan module. All references 2096 to these modules (e.g. in kernel config files) must be removed. 2097 209820080408: 2099 psm(4) has gained write(2) support in native operation level. 2100 Arbitrary commands can be written to /dev/psm%d and status can 2101 be read back from it. Therefore, an application is responsible 2102 for status validation and error recovery. It is a no-op in 2103 other operation levels. 2104 210520080312: 2106 Support for KSE threading has been removed from the kernel. To 2107 run legacy applications linked against KSE libmap.conf may 2108 be used. The following libmap.conf may be used to ensure 2109 compatibility with any prior release: 2110 2111 libpthread.so.1 libthr.so.1 2112 libpthread.so.2 libthr.so.2 2113 libkse.so.3 libthr.so.3 2114 211520080301: 2116 The layout of struct vmspace has changed. This affects libkvm 2117 and any executables that link against libkvm and use the 2118 kvm_getprocs() function. In particular, but not exclusively, 2119 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2120 The effects are minimal, but it's advisable to upgrade world 2121 nonetheless. 2122 212320080229: 2124 The latest em driver no longer has support in it for the 2125 82575 adapter, this is now moved to the igb driver. The 2126 split was done to make new features that are incompatible 2127 with older hardware easier to do. 2128 212920080220: 2130 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2131 likewise the kernel option is now GEOM_LINUX_LVM. 2132 213320080211: 2134 The default NFS mount mode has changed from UDP to TCP for 2135 increased reliability. If you rely on (insecurely) NFS 2136 mounting across a firewall you may need to update your 2137 firewall rules. 2138 213920080208: 2140 Belatedly note the addition of m_collapse for compacting 2141 mbuf chains. 2142 214320080126: 2144 The fts(3) structures have been changed to use adequate 2145 integer types for their members and so to be able to cope 2146 with huge file trees. The old fts(3) ABI is preserved 2147 through symbol versioning in libc, so third-party binaries 2148 using fts(3) should still work, although they will not take 2149 advantage of the extended types. At the same time, some 2150 third-party software might fail to build after this change 2151 due to unportable assumptions made in its source code about 2152 fts(3) structure members. Such software should be fixed 2153 by its vendor or, in the worst case, in the ports tree. 2154 FreeBSD_version 800015 marks this change for the unlikely 2155 case that a portable fix is impossible. 2156 215720080123: 2158 To upgrade to -current after this date, you must be running 2159 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2160 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2161 216220071128: 2163 The ADAPTIVE_GIANT kernel option has been retired because its 2164 functionality is the default now. 2165 216620071118: 2167 The AT keyboard emulation of sunkbd(4) has been turned on 2168 by default. In order to make the special symbols of the Sun 2169 keyboards driven by sunkbd(4) work under X these now have 2170 to be configured the same way as Sun USB keyboards driven 2171 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2172 2173 Option "XkbLayout" "us" 2174 Option "XkbRules" "xorg" 2175 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2176 217720071024: 2178 It has been decided that it is desirable to provide ABI 2179 backwards compatibility to the FreeBSD 4/5/6 versions of the 2180 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2181 broken with the introduction of PCI domain support (see the 2182 20070930 entry). Unfortunately, this required the ABI of 2183 PCIOCGETCONF to be broken again in order to be able to 2184 provide backwards compatibility to the old version of that 2185 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2186 again. As for prominent ports this affects neither pciutils 2187 nor xorg-server this time, the hal port needs to be rebuilt 2188 however. 2189 219020071020: 2191 The misnamed kthread_create() and friends have been renamed 2192 to kproc_create() etc. Many of the callers already 2193 used kproc_start().. 2194 I will return kthread_create() and friends in a while 2195 with implementations that actually create threads, not procs. 2196 Renaming corresponds with version 800002. 2197 219820071010: 2199 RELENG_7 branched. 2200 2201COMMON ITEMS: 2202 2203 General Notes 2204 ------------- 2205 Avoid using make -j when upgrading. While generally safe, there are 2206 sometimes problems using -j to upgrade. If your upgrade fails with 2207 -j, please try again without -j. From time to time in the past there 2208 have been problems using -j with buildworld and/or installworld. This 2209 is especially true when upgrading between "distant" versions (eg one 2210 that cross a major release boundary or several minor releases, or when 2211 several months have passed on the -current branch). 2212 2213 Sometimes, obscure build problems are the result of environment 2214 poisoning. This can happen because the make utility reads its 2215 environment when searching for values for global variables. To run 2216 your build attempts in an "environmental clean room", prefix all make 2217 commands with 'env -i '. See the env(1) manual page for more details. 2218 2219 When upgrading from one major version to another it is generally best 2220 to upgrade to the latest code in the currently installed branch first, 2221 then do an upgrade to the new branch. This is the best-tested upgrade 2222 path, and has the highest probability of being successful. Please try 2223 this approach before reporting problems with a major version upgrade. 2224 2225 When upgrading a live system, having a root shell around before 2226 installing anything can help undo problems. Not having a root shell 2227 around can lead to problems if pam has changed too much from your 2228 starting point to allow continued authentication after the upgrade. 2229 2230 ZFS notes 2231 --------- 2232 When upgrading the boot ZFS pool to a new version, always follow 2233 these two steps: 2234 2235 1.) recompile and reinstall the ZFS boot loader and boot block 2236 (this is part of "make buildworld" and "make installworld") 2237 2238 2.) update the ZFS boot block on your boot drive 2239 2240 The following example updates the ZFS boot block on the first 2241 partition (freebsd-boot) of a GPT partitioned drive ad0: 2242 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2243 2244 Non-boot pools do not need these updates. 2245 2246 To build a kernel 2247 ----------------- 2248 If you are updating from a prior version of FreeBSD (even one just 2249 a few days old), you should follow this procedure. It is the most 2250 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2251 2252 make kernel-toolchain 2253 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2254 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2255 2256 To test a kernel once 2257 --------------------- 2258 If you just want to boot a kernel once (because you are not sure 2259 if it works, or if you want to boot a known bad kernel to provide 2260 debugging information) run 2261 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2262 nextboot -k testkernel 2263 2264 To just build a kernel when you know that it won't mess you up 2265 -------------------------------------------------------------- 2266 This assumes you are already running a CURRENT system. Replace 2267 ${arch} with the architecture of your machine (e.g. "i386", 2268 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2269 2270 cd src/sys/${arch}/conf 2271 config KERNEL_NAME_HERE 2272 cd ../compile/KERNEL_NAME_HERE 2273 make depend 2274 make 2275 make install 2276 2277 If this fails, go to the "To build a kernel" section. 2278 2279 To rebuild everything and install it on the current system. 2280 ----------------------------------------------------------- 2281 # Note: sometimes if you are running current you gotta do more than 2282 # is listed here if you are upgrading from a really old current. 2283 2284 <make sure you have good level 0 dumps> 2285 make buildworld 2286 make kernel KERNCONF=YOUR_KERNEL_HERE 2287 [1] 2288 <reboot in single user> [3] 2289 mergemaster -p [5] 2290 make installworld 2291 mergemaster -i [4] 2292 make delete-old [6] 2293 <reboot> 2294 2295 To cross-install current onto a separate partition 2296 -------------------------------------------------- 2297 # In this approach we use a separate partition to hold 2298 # current's root, 'usr', and 'var' directories. A partition 2299 # holding "/", "/usr" and "/var" should be about 2GB in 2300 # size. 2301 2302 <make sure you have good level 0 dumps> 2303 <boot into -stable> 2304 make buildworld 2305 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2306 <maybe newfs current's root partition> 2307 <mount current's root partition on directory ${CURRENT_ROOT}> 2308 make installworld DESTDIR=${CURRENT_ROOT} 2309 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2310 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2311 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2312 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2313 <reboot into current> 2314 <do a "native" rebuild/install as described in the previous section> 2315 <maybe install compatibility libraries from ports/misc/compat*> 2316 <reboot> 2317 2318 2319 To upgrade in-place from stable to current 2320 ---------------------------------------------- 2321 <make sure you have good level 0 dumps> 2322 make buildworld [9] 2323 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2324 [1] 2325 <reboot in single user> [3] 2326 mergemaster -p [5] 2327 make installworld 2328 mergemaster -i [4] 2329 make delete-old [6] 2330 <reboot> 2331 2332 Make sure that you've read the UPDATING file to understand the 2333 tweaks to various things you need. At this point in the life 2334 cycle of current, things change often and you are on your own 2335 to cope. The defaults can also change, so please read ALL of 2336 the UPDATING entries. 2337 2338 Also, if you are tracking -current, you must be subscribed to 2339 freebsd-current@freebsd.org. Make sure that before you update 2340 your sources that you have read and understood all the recent 2341 messages there. If in doubt, please track -stable which has 2342 much fewer pitfalls. 2343 2344 [1] If you have third party modules, such as vmware, you 2345 should disable them at this point so they don't crash your 2346 system on reboot. 2347 2348 [3] From the bootblocks, boot -s, and then do 2349 fsck -p 2350 mount -u / 2351 mount -a 2352 cd src 2353 adjkerntz -i # if CMOS is wall time 2354 Also, when doing a major release upgrade, it is required that 2355 you boot into single user mode to do the installworld. 2356 2357 [4] Note: This step is non-optional. Failure to do this step 2358 can result in a significant reduction in the functionality of the 2359 system. Attempting to do it by hand is not recommended and those 2360 that pursue this avenue should read this file carefully, as well 2361 as the archives of freebsd-current and freebsd-hackers mailing lists 2362 for potential gotchas. The -U option is also useful to consider. 2363 See mergemaster(8) for more information. 2364 2365 [5] Usually this step is a noop. However, from time to time 2366 you may need to do this if you get unknown user in the following 2367 step. It never hurts to do it all the time. You may need to 2368 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2369 install) after the buildworld before this step if you last updated 2370 from current before 20130425 or from -stable before 20130430. 2371 2372 [6] This only deletes old files and directories. Old libraries 2373 can be deleted by "make delete-old-libs", but you have to make 2374 sure that no program is using those libraries anymore. 2375 2376 [8] In order to have a kernel that can run the 4.x binaries needed to 2377 do an installworld, you must include the COMPAT_FREEBSD4 option in 2378 your kernel. Failure to do so may leave you with a system that is 2379 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2380 required to run the 5.x binaries on more recent kernels. And so on 2381 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2382 2383 Make sure that you merge any new devices from GENERIC since the 2384 last time you updated your kernel config file. 2385 2386 [9] When checking out sources, you must include the -P flag to have 2387 cvs prune empty directories. 2388 2389 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2390 "?=" instead of the "=" assignment operator, so that buildworld can 2391 override the CPUTYPE if it needs to. 2392 2393 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2394 not on the command line, or in /etc/make.conf. buildworld will 2395 warn if it is improperly defined. 2396FORMAT: 2397 2398This file contains a list, in reverse chronological order, of major 2399breakages in tracking -current. It is not guaranteed to be a complete 2400list of such breakages, and only contains entries since October 10, 2007. 2401If you need to see UPDATING entries from before that date, you will need 2402to fetch an UPDATING file from an older FreeBSD release. 2403 2404Copyright information: 2405 2406Copyright 1998-2009 M.
