For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG to bootstrap to the tip of 16stable/10, and then rebuild without this option. The bootstrap process from 17older version of current is a bit fragile. 18 1920160303 p30 FreeBSD-SA-16:12.openssl 20 21 Fix multiple vulnerabilities of OpenSSL. 22 2320160130 p29 FreeBSD-SA-16:11.openssl 24 25 Fix OpenSSL SSLv2 ciphersuite downgrade vulnerability.

[SA-15:01] 211 21220141223: p3 FreeBSD-SA-14:31.ntp 213 FreeBSD-EN-14:13.freebsd-update 214 215 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 216 Fix directory deletion issue in freebsd-update. [EN-14:13] 217 21820141217: p2 FreeBSD-SA-14:30.unbound 219 Fix unbound remote denial of service vulnerability. 220 22120141210: p1 FreeBSD-SA-14:27.stdio 222 FreeBSD-SA-14:28.file 223 224 Fix buffer overflow in stdio. [SA-14:27] 225 226 Fix multiple vulnerabilities in file(1) and libmagic(3). 227 [SA-14:28] 228 22920140904: 230 The ofwfb driver, used to provide a graphics console on PowerPC when 231 using vt(4), no longer allows mmap() of all of physical memory. This 232 will prevent Xorg on PowerPC with some ATI graphics cards from 233 initializing properly unless x11-servers/xorg-server is updated to 234 1.12.4_8 or newer. 235 23620140831: 237 The libatf-c and libatf-c++ major versions were downgraded to 0 and 238 1 respectively to match the upstream numbers. They were out of 239 sync because, when they were originally added to FreeBSD, the 240 upstream versions were not respected. These libraries are private 241 and not yet built by default, so renumbering them should be a 242 non-issue. However, unclean source trees will yield broken test 243 programs once the operator executes "make delete-old-libs" after a 244 "make installworld". 245 246 Additionally, the atf-sh binary was made private by moving it into 247 /usr/libexec/. Already-built shell test programs will keep the 248 path to the old binary so they will break after "make delete-old" 249 is run. 250 251 If you are using WITH_TESTS=yes (not the default), wipe the object 252 tree and rebuild from scratch to prevent spurious test failures. 253 This is only needed once: the misnumbered libraries and misplaced 254 binaries have been added to OptionalObsoleteFiles.inc so they will 255 be removed during a clean upgrade. 256 25720140814: 258 The ixgbe tunables now match their sysctl counterparts, for example: 259 hw.ixgbe.enable_aim => hw.ix.enable_aim 260 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 261 26220140801: 263 The NFSv4.1 server committed by r269398 changes the internal 264 function call interfaces used between the NFS and krpc modules. 265 As such, __FreeBSD_version was bumped. 266 26720140729: 268 The default unbound configuration has been modified to address 269 issues with reverse lookups on networks that use private 270 address ranges. If you use the local_unbound service, run 271 "service local_unbound setup" as root to regenerate your 272 configuration, then "service local_unbound reload" to load the 273 new configuration. 274 27520140717: 276 It is no longer necessary to include the dwarf version in your DEBUG 277 options in your kernel config file. The bug that required it to be 278 placed in the config file has bene fixed. DEBUG should now just 279 contain -g. The build system will automatically update things 280 to do the right thing. 281 28220140715: 283 Several ABI breaking changes were merged to CTL and new iSCSI code. 284 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 285 iscsictl need to be rebuilt to work with a new kernel. 286 28720140708: 288 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 289 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 290 which differs from the behaviour controlled by this knob.) 291 29220140608: 293 On i386 and amd64 systems, the onifconsole flag is now set by default 294 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 295 as a login TTY if it is set in the bootloader as an active kernel 296 console. No changes in behavior should result otherwise. To revert to 297 the previous behavior, set ttyu0 to "off" in /etc/ttys. 298 29920140512: 300 Clang and llvm have been upgraded to 3.4.1 release. 301 30220140321: 303 Clang and llvm have been upgraded to 3.4 release. 304 30520140306: 306 If a Makefile in a tests/ directory was auto-generating a Kyuafile 307 instead of providing an explicit one, this would prevent such 308 Makefile from providing its own Kyuafile in the future during 309 NO_CLEAN builds. This has been fixed in the Makefiles but manual 310 intervention is needed to clean an objdir if you use NO_CLEAN: 311 # find /usr/obj -name Kyuafile | xargs rm -f 312 31320140303: 314 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 315 capability mode support. Please note that enabling the feature in 316 kernel is still highly recommended. 317 31820140227: 319 OpenSSH is now built with sandbox support, and will use sandbox as 320 the default privilege separation method. This requires Capsicum 321 capability mode support in kernel. 322 32320140216: 324 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 325 been deprecated and will not be part of FreeBSD 11.0 and later 326 releases. If you use this driver, please consider switching to 327 the nfe(4) driver instead. 328 32920140120: 330 10.0-RELEASE. 331 33220131216: 333 The behavior of gss_pseudo_random() for the krb5 mechanism 334 has changed, for applications requesting a longer random string 335 than produced by the underlying enctype's pseudo-random() function. 336 In particular, the random string produced from a session key of 337 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 338 be different at the 17th octet and later, after this change. 339 The counter used in the PRF+ construction is now encoded as a 340 big-endian integer in accordance with RFC 4402. 341 __FreeBSD_version is bumped to 1000701. 342 34320131108: 344 The WITHOUT_ATF build knob has been removed and its functionality 345 has been subsumed into the more generic WITHOUT_TESTS. If you were 346 using the former to disable the build of the ATF libraries, you 347 should change your settings to use the latter. 348 34920131031: 350 The default version of mtree is nmtree which is obtained from 351 NetBSD. The output is generally the same, but may vary 352 slightly. If you found you need identical output adding 353 "-F freebsd9" to the command line should do the trick. For the 354 time being, the old mtree is available as fmtree. 355 35620131014: 357 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 358 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 359 1.1.4_8 and verify bsdyml not linked in, before running "make 360 delete-old-libs": 361 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 362 or 363 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 364 36520131010: 366 The rc.d/jail script has been updated to support jail(8) 367 configuration file. The "jail_<jname>_*" rc.conf(5) variables 368 for per-jail configuration are automatically converted to 369 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 370 This is transparently backward compatible. See below about some 371 incompatibilities and rc.conf(5) manual page for more details. 372 373 These variables are now deprecated in favor of jail(8) configuration 374 file. One can use "rc.d/jail config <jname>" command to generate 375 a jail(8) configuration file in /var/run/jail.<jname>.conf without 376 running the jail(8) utility. The default pathname of the 377 configuration file is /etc/jail.conf and can be specified by 378 using $jail_conf or $jail_<jname>_conf variables. 379 380 Please note that jail_devfs_ruleset accepts an integer at 381 this moment. Please consider to rewrite the ruleset name 382 with an integer. 383 38420130930: 385 BIND has been removed from the base system. If all you need 386 is a local resolver, simply enable and start the local_unbound 387 service instead. Otherwise, several versions of BIND are 388 available in the ports tree. The dns/bind99 port is one example. 389 390 With this change, nslookup(1) and dig(1) are no longer in the base 391 system. Users should instead use host(1) and drill(1) which are 392 in the base system. Alternatively, nslookup and dig can 393 be obtained by installing the dns/bind-tools port. 394 39520130916: 396 With the addition of unbound(8), a new unbound user is now 397 required during installworld. "mergemaster -p" can be used to 398 add the user prior to installworld, as documented in the handbook. 399 40020130911: 401 OpenSSH is now built with DNSSEC support, and will by default 402 silently trust signed SSHFP records. This can be controlled with 403 the VerifyHostKeyDNS client configuration setting. DNSSEC support 404 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 405 40620130906: 407 The GNU Compiler Collection and C++ standard library (libstdc++) 408 are no longer built by default on platforms where clang is the system 409 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 410 options in src.conf. 411 41220130905: 413 The PROCDESC kernel option is now part of the GENERIC kernel 414 configuration and is required for the rwhod(8) to work. 415 If you are using custom kernel configuration, you should include 416 'options PROCDESC'. 417 41820130905: 419 The API and ABI related to the Capsicum framework was modified 420 in backward incompatible way. The userland libraries and programs 421 have to be recompiled to work with the new kernel. This includes the 422 following libraries and programs, but the whole buildworld is 423 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 424 kdump, procstat, rwho, rwhod, uniq. 425 42620130903: 427 AES-NI intrinsic support has been added to gcc. The AES-NI module 428 has been updated to use this support. A new gcc is required to build 429 the aesni module on both i386 and amd64. 430 43120130821: 432 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 433 Thus "device padlock_rng" and "device rdrand_rng" should be 434 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 435 43620130813: 437 WITH_ICONV has been split into two feature sets. WITH_ICONV now 438 enables just the iconv* functionality and is now on by default. 439 WITH_LIBICONV_COMPAT enables the libiconv api and link time 440 compatability. Set WITHOUT_ICONV to build the old way. 441 If you have been using WITH_ICONV before, you will very likely 442 need to turn on WITH_LIBICONV_COMPAT. 443 44420130806: 445 INVARIANTS option now enables DEBUG for code with OpenSolaris and 446 Illumos origin, including ZFS. If you have INVARIANTS in your 447 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 448 explicitly. 449 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 450 locks if WITNESS option was set. Because that generated a lot of 451 witness(9) reports and all of them were believed to be false 452 positives, this is no longer done. New option OPENSOLARIS_WITNESS 453 can be used to achieve the previous behavior. 454 45520130806: 456 Timer values in IPv6 data structures now use time_uptime instead 457 of time_second. Although this is not a user-visible functional 458 change, userland utilities which directly use them---ndp(8), 459 rtadvd(8), and rtsold(8) in the base system---need to be updated 460 to r253970 or later. 461 46220130802: 463 find -delete can now delete the pathnames given as arguments, 464 instead of only files found below them or if the pathname did 465 not contain any slashes. Formerly, the following error message 466 would result: 467 468 find: -delete: <path>: relative path potentially not safe 469 470 Deleting the pathnames given as arguments can be prevented 471 without error messages using -mindepth 1 or by changing 472 directory and passing "." as argument to find. This works in the 473 old as well as the new version of find. 474 47520130726: 476 Behavior of devfs rules path matching has been changed. 477 Pattern is now always matched against fully qualified devfs 478 path and slash characters must be explicitly matched by 479 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 480 subdirectories must be reviewed. 481 48220130716: 483 The default ARM ABI has changed to the ARM EABI. The old ABI is 484 incompatible with the ARM EABI and all programs and modules will 485 need to be rebuilt to work with a new kernel. 486 487 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 488 489 NOTE: Support for the old ABI will be removed in the future and 490 users are advised to upgrade. 491 49220130709: 493 pkg_install has been disconnected from the build if you really need it 494 you should add WITH_PKGTOOLS in your src.conf(5). 495 49620130709: 497 Most of network statistics structures were changed to be able 498 keep 64-bits counters. Thus all tools, that work with networking 499 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 500 50120130629: 502 Fix targets that run multiple make's to use && rather than ; 503 so that subsequent steps depend on success of previous. 504 505 NOTE: if building 'universe' with -j* on stable/8 or stable/9 506 it would be better to start the build using bmake, to avoid 507 overloading the machine. 508 50920130618: 510 Fix a bug that allowed a tracing process (e.g. gdb) to write 511 to a memory-mapped file in the traced process's address space 512 even if neither the traced process nor the tracing process had 513 write access to that file. 514 51520130615: 516 CVS has been removed from the base system. An exact copy 517 of the code is available from the devel/cvs port. 518 51920130613: 520 Some people report the following error after the switch to bmake: 521 522 make: illegal option -- J 523 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 524 ... 525 *** [buildworld] Error code 2 526 527 this likely due to an old instance of make in 528 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 529 which src/Makefile will use that blindly, if it exists, so if 530 you see the above error: 531 532 rm -rf `make -V MAKEPATH` 533 534 should resolve it. 535 53620130516: 537 Use bmake by default. 538 Whereas before one could choose to build with bmake via 539 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 540 make. The goal is to remove these knobs for 10-RELEASE. 541 542 It is worth noting that bmake (like gmake) treats the command 543 line as the unit of failure, rather than statements within the 544 command line. Thus '(cd some/where && dosomething)' is safer 545 than 'cd some/where; dosomething'. The '()' allows consistent 546 behavior in parallel build. 547 54820130429: 549 Fix a bug that allows NFS clients to issue READDIR on files. 550 55120130426: 552 The WITHOUT_IDEA option has been removed because 553 the IDEA patent expired. 554 55520130426: 556 The sysctl which controls TRIM support under ZFS has been renamed 557 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 558 enabled by default. 559 56020130425: 561 The mergemaster command now uses the default MAKEOBJDIRPREFIX 562 rather than creating it's own in the temporary directory in 563 order allow access to bootstrapped versions of tools such as 564 install and mtree. When upgrading from version of FreeBSD where 565 the install command does not support -l, you will need to 566 install a new mergemaster command if mergemaster -p is required. 567 This can be accomplished with the command (cd src/usr.sbin/mergemaster 568 && make install). 569 57020130404: 571 Legacy ATA stack, disabled and replaced by new CAM-based one since 572 FreeBSD 9.0, completely removed from the sources. Kernel modules 573 atadisk and atapi*, user-level tools atacontrol and burncd are 574 removed. Kernel option `options ATA_CAM` is now permanently enabled 575 and removed. 576 57720130319: 578 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 579 and socketpair(2). Software, in particular Kerberos, may 580 automatically detect and use these during building. The resulting 581 binaries will not work on older kernels. 582 58320130308: 584 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 585 information, see the respective 20130304 entry). 586 58720130304: 588 Recent commits to callout(9) changed the size of struct callout, 589 so the KBI is probably heavily disturbed. Also, some functions 590 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 591 by macros. Every kernel module using it won't load, so rebuild 592 is requested. 593 594 The ctl device has been re-enabled in GENERIC for i386 and amd64, 595 but does not initialize by default (because of the new CTL_DISABLE 596 option) to save memory. To re-enable it, remove the CTL_DISABLE 597 option from the kernel config file or set kern.cam.ctl.disable=0 598 in /boot/loader.conf. 599 60020130301: 601 The ctl device has been disabled in GENERIC for i386 and amd64. 602 This was done due to the extra memory being allocated at system 603 initialisation time by the ctl driver which was only used if 604 a CAM target device was created. This makes a FreeBSD system 605 unusable on 128MB or less of RAM. 606 60720130208: 608 A new compression method (lz4) has been merged to -HEAD. Please 609 refer to zpool-features(7) for more information. 610 611 Please refer to the "ZFS notes" section of this file for information 612 on upgrading boot ZFS pools. 613 61420130129: 615 A BSD-licensed patch(1) variant has been added and is installed 616 as bsdpatch, being the GNU version the default patch. 617 To inverse the logic and use the BSD-licensed one as default, 618 while having the GNU version installed as gnupatch, rebuild 619 and install world with the WITH_BSD_PATCH knob set. 620 62120130121: 622 Due to the use of the new -l option to install(1) during build 623 and install, you must take care not to directly set the INSTALL 624 make variable in your /etc/make.conf, /etc/src.conf, or on the 625 command line. If you wish to use the -C flag for all installs 626 you may be able to add INSTALL+=-C to /etc/make.conf or 627 /etc/src.conf. 628 62920130118: 630 The install(1) option -M has changed meaning and now takes an 631 argument that is a file or path to append logs to. In the 632 unlikely event that -M was the last option on the command line 633 and the command line contained at least two files and a target 634 directory the first file will have logs appended to it. The -M 635 option served little practical purpose in the last decade so its 636 use is expected to be extremely rare. 637 63820121223: 639 After switching to Clang as the default compiler some users of ZFS 640 on i386 systems started to experience stack overflow kernel panics. 641 Please consider using 'options KSTACK_PAGES=4' in such configurations. 642 64320121222: 644 GEOM_LABEL now mangles label names read from file system metadata. 645 Mangling affect labels containing spaces, non-printable characters, 646 '%' or '"'. Device names in /etc/fstab and other places may need to 647 be updated. 648 64920121217: 650 By default, only the 10 most recent kernel dumps will be saved. To 651 restore the previous behaviour (no limit on the number of kernel dumps 652 stored in the dump directory) add the following line to /etc/rc.conf: 653 654 savecore_flags="" 655 65620121201: 657 With the addition of auditdistd(8), a new auditdistd user is now 658 required during installworld. "mergemaster -p" can be used to 659 add the user prior to installworld, as documented in the handbook. 660 66120121117: 662 The sin6_scope_id member variable in struct sockaddr_in6 is now 663 filled by the kernel before passing the structure to the userland via 664 sysctl or routing socket. This means the KAME-specific embedded scope 665 id in sin6_addr.s6_addr[2] is always cleared in userland application. 666 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 667 __FreeBSD_version is bumped to 1000025. 668 66920121105: 670 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 671 This means that the world and kernel will be compiled with clang 672 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 673 and /usr/bin/cpp. To disable this behavior and revert to building 674 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 675 of current may need to bootstrap WITHOUT_CLANG first if the clang 676 build fails (its compatibility window doesn't extend to the 9 stable 677 branch point). 678 67920121102: 680 The IPFIREWALL_FORWARD kernel option has been removed. Its 681 functionality now turned on by default. 682 68320121023: 684 The ZERO_COPY_SOCKET kernel option has been removed and 685 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 686 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 687 mechanism which is not safe and may result in kernel crashes. 688 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 689 driver supports disposeable external page sized mbuf storage. 690 Proper replacements for both zero-copy mechanisms are under 691 consideration and will eventually lead to complete removal 692 of the two kernel options. 693 69420121023: 695 The IPv4 network stack has been converted to network byte 696 order. The following modules need to be recompiled together 697 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 698 pf(4), ipfw(4), ng_ipfw(4), stf(4). 699 70020121022: 701 Support for non-MPSAFE filesystems was removed from VFS. The 702 VFS_VERSION was bumped, all filesystem modules shall be 703 recompiled. 704 70520121018: 706 All the non-MPSAFE filesystems have been disconnected from 707 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 708 portalfs, smbfs, xfs. 709 71020121016: 711 The interface cloning API and ABI has changed. The following 712 modules need to be recompiled together with kernel: 713 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 714 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 715 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 716 71720121015: 718 The sdhci driver was split in two parts: sdhci (generic SD Host 719 Controller logic) and sdhci_pci (actual hardware driver). 720 No kernel config modifications are required, but if you 721 load sdhc as a module you must switch to sdhci_pci instead. 722 72320121014: 724 Import the FUSE kernel and userland support into base system. 725 72620121013: 727 The GNU sort(1) program has been removed since the BSD-licensed 728 sort(1) has been the default for quite some time and no serious 729 problems have been reported. The corresponding WITH_GNU_SORT 730 knob has also gone. 731 73220121006: 733 The pfil(9) API/ABI for AF_INET family has been changed. Packet 734 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 735 with new kernel. 736 73720121001: 738 The net80211(4) ABI has been changed to allow for improved driver 739 PS-POLL and power-save support. All wireless drivers need to be 740 recompiled to work with the new kernel. 741 74220120913: 743 The random(4) support for the VIA hardware random number 744 generator (`PADLOCK') is no longer enabled unconditionally. 745 Add the padlock_rng device in the custom kernel config if 746 needed. The GENERIC kernels on i386 and amd64 do include the 747 device, so the change only affects the custom kernel 748 configurations. 749 75020120908: 751 The pf(4) packet filter ABI has been changed. pfctl(8) and 752 snmp_pf module need to be recompiled to work with new kernel. 753 75420120828: 755 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 756 to -HEAD. Pools that have empty_bpobj in active state can not be 757 imported read-write with ZFS implementations that do not support 758 this feature. For more information read the zpool-features(5) 759 manual page. 760 76120120727: 762 The sparc64 ZFS loader has been changed to no longer try to auto- 763 detect ZFS providers based on diskN aliases but now requires these 764 to be explicitly listed in the OFW boot-device environment variable. 765 76620120712: 767 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 768 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 769 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 770 77120120712: 772 The following sysctls and tunables have been renamed for consistency 773 with other variables: 774 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 775 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 776 77720120628: 778 The sort utility has been replaced with BSD sort. For now, GNU sort 779 is also available as "gnusort" or the default can be set back to 780 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 781 installed as "bsdsort". 782 78320120611: 784 A new version of ZFS (pool version 5000) has been merged to -HEAD. 785 Starting with this version the old system of ZFS pool versioning 786 is superseded by "feature flags". This concept enables forward 787 compatibility against certain future changes in functionality of ZFS 788 pools. The first read-only compatible "feature flag" for ZFS pools 789 is named "com.delphix:async_destroy". For more information 790 read the new zpool-features(5) manual page. 791 Please refer to the "ZFS notes" section of this file for information 792 on upgrading boot ZFS pools. 793 79420120417: 795 The malloc(3) implementation embedded in libc now uses sources imported 796 as contrib/jemalloc. The most disruptive API change is to 797 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 798 delete it prior to installworld, and optionally re-create it using the 799 new format after rebooting. See malloc.conf(5) for details 800 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 801 NAMESPACE section). 802 80320120328: 804 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 805 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 806 now spelled mips. This is to aid compatibility with third-party 807 software that expects this naming scheme in uname(3). Little-endian 808 settings are unchanged. If you are updating a big-endian mips64 machine 809 from before this change, you may need to set MACHINE_ARCH=mips64 in 810 your environment before the new build system will recognize your machine. 811 81220120306: 813 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 814 platforms. 815 81620120229: 817 Now unix domain sockets behave "as expected" on nullfs(5). Previously 818 nullfs(5) did not pass through all behaviours to the underlying layer, 819 as a result if we bound to a socket on the lower layer we could connect 820 only to the lower path; if we bound to the upper layer we could connect 821 only to the upper path. The new behavior is one can connect to both the 822 lower and the upper paths regardless what layer path one binds to. 823 82420120211: 825 The getifaddrs upgrade path broken with 20111215 has been restored. 826 If you have upgraded in between 20111215 and 20120209 you need to 827 recompile libc again with your kernel. You still need to recompile 828 world to be able to configure CARP but this restriction already 829 comes from 20111215. 830 83120120114: 832 The set_rcvar() function has been removed from /etc/rc.subr. All 833 base and ports rc.d scripts have been updated, so if you have a 834 port installed with a script in /usr/local/etc/rc.d you can either 835 hand-edit the rcvar= line, or reinstall the port. 836 837 An easy way to handle the mass-update of /etc/rc.d: 838 rm /etc/rc.d/* && mergemaster -i 839 84020120109: 841 panic(9) now stops other CPUs in the SMP systems, disables interrupts 842 on the current CPU and prevents other threads from running. 843 This behavior can be reverted using the kern.stop_scheduler_on_panic 844 tunable/sysctl. 845 The new behavior can be incompatible with kern.sync_on_panic. 846 84720111215: 848 The carp(4) facility has been changed significantly. Configuration 849 of the CARP protocol via ifconfig(8) has changed, as well as format 850 of CARP events submitted to devd(8) has changed. See manual pages 851 for more information. The arpbalance feature of carp(4) is currently 852 not supported anymore. 853 854 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 855 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 856 need to be recompiled. 857 85820111122: 859 The acpi_wmi(4) status device /dev/wmistat has been renamed to 860 /dev/wmistat0. 861 86220111108: 863 The option VFS_ALLOW_NONMPSAFE option has been added in order to 864 explicitely support non-MPSAFE filesystems. 865 It is on by default for all supported platform at this present 866 time. 867 86820111101: 869 The broken amd(4) driver has been replaced with esp(4) in the amd64, 870 i386 and pc98 GENERIC kernel configuration files. 871 87220110930: 873 sysinstall has been removed 874 87520110923: 876 The stable/9 branch created in subversion. This corresponds to the 877 RELENG_9 branch in CVS. 878 87920110913: 880 This commit modifies vfs_register() so that it uses a hash 881 calculation to set vfc_typenum, which is enabled by default. 882 The first time a system is booted after this change, the 883 vfc_typenum values will change for all file systems. The 884 main effect of this is a change to the NFS server file handles 885 for file systems that use vfc_typenum in their fsid, such as ZFS. 886 It will, however, prevent vfc_typenum from changing when file 887 systems are loaded in a different order for subsequent reboots. 888 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 889 until you are ready to remount all NFS clients after a reboot. 890 89120110828: 892 Bump the shared library version numbers for libraries that 893 do not use symbol versioning, have changed the ABI compared 894 to stable/8 and which shared library version was not bumped. 895 Done as part of 9.0-RELEASE cycle. 896 89720110815: 898 During the merge of Capsicum features, the fget(9) KPI was modified. 899 This may require the rebuilding of out-of-tree device drivers -- 900 issues have been reported specifically with the nVidia device driver. 901 __FreeBSD_version is bumped to 900041. 902 903 Also, there is a period between 20110811 and 20110814 where the 904 special devices /dev/{stdin,stdout,stderr} did not work correctly. 905 Building world from a kernel during that window may not work. 906 90720110628: 908 The packet filter (pf) code has been updated to OpenBSD 4.5. 909 You need to update userland tools to be in sync with kernel. 910 This update breaks backward compatibility with earlier pfsync(4) 911 versions. Care must be taken when updating redundant firewall setups. 912 91320110608: 914 The following sysctls and tunables are retired on x86 platforms: 915 machdep.hlt_cpus 916 machdep.hlt_logical_cpus 917 The following sysctl is retired: 918 machdep.hyperthreading_allowed 919 The sysctls were supposed to provide a way to dynamically offline and 920 online selected CPUs on x86 platforms, but the implementation has not 921 been reliable especially with SCHED_ULE scheduler. 922 machdep.hyperthreading_allowed tunable is still available to ignore 923 hyperthreading CPUs at OS level. 924 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 925 where X is an APIC ID of a CPU. Be advised, though, that disabling 926 CPUs in non-uniform fashion will result in non-uniform topology and 927 may lead to sub-optimal system performance with SCHED_ULE, which is 928 a default scheduler. 929 93020110607: 931 cpumask_t type is retired and cpuset_t is used in order to describe 932 a mask of CPUs. 933 93420110531: 935 Changes to ifconfig(8) for dynamic address family detection mandate 936 that you are running a kernel of 20110525 or later. Make sure to 937 follow the update procedure to boot a new kernel before installing 938 world. 939 94020110513: 941 Support for sun4v architecture is officially dropped 942 94320110503: 944 Several KPI breaking changes have been committed to the mii(4) layer, 945 the PHY drivers and consequently some Ethernet drivers using mii(4). 946 This means that miibus.ko and the modules of the affected Ethernet 947 drivers need to be recompiled. 948 949 Note to kernel developers: Given that the OUI bit reversion problem 950 was fixed as part of these changes all mii(4) commits related to OUIs, 951 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 952 handling, no longer can be merged verbatim to stable/8 and previous 953 branches. 954 95520110430: 956 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 957 into their kernel configurations along with 'device pci'. 958 95920110427: 960 The default NFS client is now the new NFS client, so fstype "newnfs" 961 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 962 Although mounts via fstype "nfs" will usually work without userland 963 changes, it is recommended that the mount(8) and mount_nfs(8) 964 commands be rebuilt from sources and that a link to mount_nfs called 965 mount_oldnfs be created. The new client is compiled into the 966 kernel with "options NFSCL" and this is needed for diskless root 967 file systems. The GENERIC kernel configs have been changed to use 968 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 969 To use the regular/old client, you can "mount -t oldnfs ...". For 970 a diskless root file system, you must also include a line like: 971 972 vfs.root.mountfrom="oldnfs:" 973 974 in the boot/loader.conf on the root fs on the NFS server to make 975 a diskless root fs use the old client. 976 97720110424: 978 The GENERIC kernels for all architectures now default to the new 979 CAM-based ATA stack. It means that all legacy ATA drivers were 980 removed and replaced by respective CAM drivers. If you are using 981 ATA device names in /etc/fstab or other places, make sure to update 982 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 983 where 'Y's are the sequential numbers starting from zero for each type 984 in order of detection, unless configured otherwise with tunables, 985 see cam(4)). There will be symbolic links created in /dev/ to map 986 old adX devices to the respective adaY. They should provide basic 987 compatibility for file systems mounting in most cases, but they do 988 not support old user-level APIs and do not have respective providers 989 in GEOM. Consider using updated management tools with new device names. 990 991 It is possible to load devices ahci, ata, siis and mvs as modules, 992 but option ATA_CAM should remain in kernel configuration to make ata 993 module work as CAM driver supporting legacy ATA controllers. Device ata 994 still can be used in modular fashion (atacore + ...). Modules atadisk 995 and atapi* are not used and won't affect operation in ATA_CAM mode. 996 Note that to use CAM-based ATA kernel should include CAM devices 997 scbus, pass, da (or explicitly ada), cd and optionally others. All of 998 them are parts of the cam module. 999 1000 ataraid(4) functionality is now supported by the RAID GEOM class. 1001 To use it you can load geom_raid kernel module and use graid(8) tool 1002 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1003 1004 No kernel config options or code have been removed, so if a problem 1005 arises, please report it and optionally revert to the old ATA stack. 1006 In order to do it you can remove from the kernel config: 1007 options ATA_CAM 1008 device ahci 1009 device mvs 1010 device siis 1011 , and instead add back: 1012 device atadisk # ATA disk drives 1013 device ataraid # ATA RAID drives 1014 device atapicd # ATAPI CDROM drives 1015 device atapifd # ATAPI floppy drives 1016 device atapist # ATAPI tape drives 1017 101820110423: 1019 The default NFS server has been changed to the new server, which 1020 was referred to as the experimental server. If you need to switch 1021 back to the old NFS server, you must now put the "-o" option on 1022 both the mountd and nfsd commands. This can be done using the 1023 mountd_flags and nfs_server_flags rc.conf variables until an 1024 update to the rc scripts is committed, which is coming soon. 1025 102620110418: 1027 The GNU Objective-C runtime library (libobjc), and other Objective-C 1028 related components have been removed from the base system. If you 1029 require an Objective-C library, please use one of the available ports. 1030 103120110331: 1032 ath(4) has been split into bus- and device- modules. if_ath contains 1033 the HAL, the TX rate control and the network device code. if_ath_pci 1034 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1035 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1036 in order to use ath on everything else. 1037 1038 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1039 need to load if_ath and if_ath_pci for ath(4) operation. 1040 104120110314: 1042 As part of the replacement of sysinstall, the process of building 1043 release media has changed significantly. For details, please re-read 1044 release(7), which has been updated to reflect the new build process. 1045 104620110218: 1047 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1048 is the last available version under GPLv2. It brings a number of new 1049 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1050 4.1 and SSE 4.2), better support for powerpc64, a number of new 1051 directives, and lots of other small improvements. See the ChangeLog 1052 file in contrib/binutils for the full details. 1053 105420110218: 1055 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1056 compliant, and will now use half of hash for authentication. 1057 This will break interoperability with all stacks (including all 1058 actual FreeBSD versions) who implement 1059 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1060 authentication). 1061 The only workaround with such peers is to use another HMAC 1062 algorithm for IPsec ("phase 2") authentication. 1063 106420110207: 1065 Remove the uio_yield prototype and symbol. This function has 1066 been misnamed since it was introduced and should not be 1067 globally exposed with this name. The equivalent functionality 1068 is now available using kern_yield(curthread->td_user_pri). 1069 The function remains undocumented. 1070 107120110112: 1072 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1073 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1074 for scalar sysctls is defined but disabled. Code that needs 1075 UQUAD to pass the type checking that must compile on older 1076 systems where the define is not present can check against 1077 __FreeBSD_version >= 900030. 1078 1079 The system dialog(1) has been replaced with a new version previously 1080 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1081 with the previous version, but the libdialog associated with it has 1082 a largely incompatible API. As such, the original version of libdialog 1083 will be kept temporarily as libodialog, until its base system consumers 1084 are replaced or updated. Bump __FreeBSD_version to 900030. 1085 108620110103: 1087 If you are trying to run make universe on a -stable system, and you get 1088 the following warning: 1089 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1090 unknown. config(8) likely too old." 1091 or something similar to it, then you must upgrade your -stable system 1092 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1093 stable/8) or build the config from the latest stable/8 branch and 1094 install it on your system. 1095 1096 Prior to this date, building a current universe on 8-stable system from 1097 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1098 error in the first kernel build phase. A new config on those old 1099 systems will fix that problem for older versions of -current. 1100 110120101228: 1102 The TCP stack has been modified to allow Khelp modules to interact with 1103 it via helper hook points and store per-connection data in the TCP 1104 control block. Bump __FreeBSD_version to 900029. User space tools that 1105 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1106 be recompiled. 1107 110820101114: 1109 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1110 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1111 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1112 to take advantage of it instead of using custom implementations. This 1113 means that these drivers now no longer unconditionally advertise 1114 support for flow control but only do so if flow control is a selected 1115 media option. This was implemented in the generic support that way in 1116 order to allow flow control to be switched on and off via ifconfig(8) 1117 with the PHY specific default to typically off in order to protect 1118 from unwanted effects. Consequently, if you used flow control with 1119 one of the above mentioned drivers you now need to explicitly enable 1120 it, for example via: 1121 ifconfig bge0 media auto mediaopt flowcontrol 1122 1123 Along with the above mentioned changes generic support for setting 1124 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1125 e1000phy(4) as well as ip1000phy(4) have been converted to take 1126 advantage of it. This means that these drivers now no longer take the 1127 link0 parameter for selecting master mode but the master media option 1128 has to be used instead, for example like in the following: 1129 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1130 1131 Selection of master mode now is also available with all other PHY 1132 drivers supporting 1000baseT. 1133 113420101111: 1135 The TCP stack has received a significant update to add support for 1136 modularised congestion control and generally improve the clarity of 1137 congestion control decisions. Bump __FreeBSD_version to 900025. User 1138 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1139 sockstat) need to be recompiled. 1140 114120101002: 1142 The man(1) utility has been replaced by a new version that no longer 1143 uses /etc/manpath.config. Please consult man.conf(5) for how to 1144 migrate local entries to the new format. 1145 114620100928: 1147 The copyright strings printed by login(1) and sshd(8) at the time of a 1148 new connection have been removed to follow other operating systems and 1149 upstream sshd. 1150 115120100915: 1152 A workaround for a fixed ld bug has been removed in kernel code, 1153 so make sure that your system ld is built from sources after 1154 revision 210245 from 2010-07-19 (r211583 if building head kernel 1155 on stable/8, r211584 for stable/7; both from 2010-08-21). 1156 A symptom of incorrect ld version is different addresses for 1157 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1158 115920100913: 1160 The $ipv6_prefer variable in rc.conf(5) has been split into 1161 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1162 1163 The $ip6addrctl_policy is a variable to choose a pre-defined 1164 address selection policy set by ip6addrctl(8). A value 1165 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1166 default is "AUTO". 1167 1168 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1169 flag (see an entry of 20090926) is set on an interface with no 1170 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1171 security reason. If you want IPv6 link-local address on all 1172 interfaces by default, set this to "YES". 1173 1174 The old ipv6_prefer="YES" is equivalent to 1175 ipv6_activate_all_interfaces="YES" and 1176 ip6addrctl_policy="ipv6_prefer". 1177 117820100913: 1179 DTrace has grown support for userland tracing. Due to this, DTrace is 1180 now i386 and amd64 only. 1181 dtruss(1) is now installed by default on those systems and a new 1182 kernel module is needed for userland tracing: fasttrap. 1183 No changes to your kernel config file are necessary to enable 1184 userland tracing, but you might consider adding 'STRIP=' and 1185 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1186 to have informative userland stack traces in DTrace (ustack). 1187 118820100725: 1189 The acpi_aiboost(4) driver has been removed in favor of the new 1190 aibs(4) driver. You should update your kernel configuration file. 1191 119220100722: 1193 BSD grep has been imported to the base system and it is built by 1194 default. It is completely BSD licensed, highly GNU-compatible, uses 1195 less memory than its GNU counterpart and has a small codebase. 1196 However, it is slower than its GNU counterpart, which is mostly 1197 noticeable for larger searches, for smaller ones it is measurable 1198 but not significant. The reason is complex, the most important factor 1199 is that we lack a modern and efficient regex library and GNU 1200 overcomes this by optimizing the searches internally. Future work 1201 on improving the regex performance is planned, for the meantime, 1202 users that need better performance, can build GNU grep instead by 1203 setting the WITH_GNU_GREP knob. 1204 120520100713: 1206 Due to the import of powerpc64 support, all existing powerpc kernel 1207 configuration files must be updated with a machine directive like this: 1208 machine powerpc powerpc 1209 1210 In addition, an updated config(8) is required to build powerpc kernels 1211 after this change. 1212 121320100713: 1214 A new version of ZFS (version 15) has been merged to -HEAD. 1215 This version uses a python library for the following subcommands: 1216 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1217 For full functionality of these commands the following port must 1218 be installed: sysutils/py-zfs 1219 122020100429: 1221 'vm_page's are now hashed by physical address to an array of mutexes. 1222 Currently this is only used to serialize access to hold_count. Over 1223 time the page queue mutex will be peeled away. This changes the size 1224 of pmap on every architecture. And requires all callers of vm_page_hold 1225 and vm_page_unhold to be updated. 1226 122720100402: 1228 WITH_CTF can now be specified in src.conf (not recommended, there 1229 are some problems with static executables), make.conf (would also 1230 affect ports which do not use GNU make and do not override the 1231 compile targets) or in the kernel config (via "makeoptions 1232 WITH_CTF=yes"). 1233 When WITH_CTF was specified there before this was silently ignored, 1234 so make sure that WITH_CTF is not used in places which could lead 1235 to unwanted behavior. 1236 123720100311: 1238 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1239 to allow 32-bit compatibility on non-x86 platforms. All kernel 1240 configurations on amd64 and ia64 platforms using these options must 1241 be modified accordingly. 1242 124320100113: 1244 The utmp user accounting database has been replaced with utmpx, 1245 the user accounting interface standardized by POSIX. 1246 Unfortunately the semantics of utmp and utmpx don't match, 1247 making it practically impossible to support both interfaces. 1248 The user accounting database is used by tools like finger(1), 1249 last(1), talk(1), w(1) and ac(8). 1250 1251 All applications in the base system use utmpx. This means only 1252 local binaries (e.g. from the ports tree) may still use these 1253 utmp database files. These applications must be rebuilt to make 1254 use of utmpx. 1255 1256 After the system has been upgraded, it is safe to remove the old 1257 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1258 assuming their contents is of no importance anymore. Old wtmp 1259 databases can only be used by last(1) and ac(8) after they have 1260 been converted to the new format using wtmpcvt(1). 1261 126220100108: 1263 Introduce the kernel thread "deadlock resolver" (which can be enabled 1264 via the DEADLKRES option, see NOTES for more details) and the 1265 sleepq_type() function for sleepqueues. 1266 126720091202: 1268 The rc.firewall and rc.firewall6 were unified, and 1269 rc.firewall6 and rc.d/ip6fw were removed. 1270 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1271 variables are obsoleted. Instead, the following new rc 1272 variables are added to rc.d/ipfw: 1273 1274 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1275 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1276 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1277 1278 The meanings correspond to the relevant IPv4 variables. 1279 128020091125: 1281 8.0-RELEASE. 1282 128320091113: 1284 The default terminal emulation for syscons(4) has been changed 1285 from cons25 to xterm on all platforms except pc98. This means 1286 that the /etc/ttys file needs to be updated to ensure correct 1287 operation of applications on the console. 1288 1289 The terminal emulation style can be toggled per window by using 1290 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1291 options can be used to change the compile-time default back to 1292 cons25. 1293 1294 To prevent graphical artifacts, make sure the TERM environment 1295 variable is set to match the terminal emulation that is being 1296 performed by syscons(4). 1297 129820091109: 1299 The layout of the structure ieee80211req_scan_result has changed. 1300 Applications that require wireless scan results (e.g. ifconfig(8)) 1301 from net80211 need to be recompiled. 1302 1303 Applications such as wpa_supplicant(8) may require a full world 1304 build without using NO_CLEAN in order to get synchronized with the 1305 new structure. 1306 130720091025: 1308 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1309 There's one kernel module for each firmware. Adding "device iwnfw" 1310 to the kernel configuration file means including all three firmware 1311 images inside the kernel. If you want to include just the one for 1312 your wireless card, use the devices iwn4965fw, iwn5000fw or 1313 iwn5150fw. 1314 131520090926: 1316 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1317 into rc.d/netif. The changes are the following: 1318 1319 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1320 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1321 Note that both variables need the "inet6" keyword at the head. 1322 1323 Do not set $ipv6_network_interfaces manually if you do not 1324 understand what you are doing. It is not needed in most cases. 1325 1326 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1327 they are obsolete. 1328 1329 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1330 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1331 1332 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1333 all configured interfaces have "inet6 accept_rtadv" in the 1334 $ifconfig_IF_ipv6. These are for backward compatibility. 1335 1336 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1337 functionality of interfaces with no corresponding 1338 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1339 and the default address selection policy of ip6addrctl(8) 1340 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1341 Note that if you want to configure IPv6 functionality on the 1342 disabled interfaces after boot, first you need to clear the flag by 1343 using ifconfig(8) like: 1344 1345 ifconfig em0 inet6 -ifdisabled 1346 1347 If YES, the default address selection policy is set as 1348 IPv6-preferred. 1349 1350 The default value of $ipv6_prefer is NO. 1351 1352 4. If your system need to receive Router Advertisement messages, 1353 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1354 scripts automatically invoke rtsol(8) when the interface becomes 1355 UP. The Router Advertisement messages are used for SLAAC 1356 (State-Less Address AutoConfiguration). 1357 135820090922: 1359 802.11s D3.03 support was committed. This is incompatible with the 1360 previous code, which was based on D3.0. 1361 136220090912: 1363 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1364 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1365 control whether accepting Router Advertisement messages or not. 1366 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1367 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1368 The ifconfig(8) utility now supports these flags. 1369 137020090910: 1371 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1372 mount(8) and -a option for df(1) to see them. 1373 137420090825: 1375 The old tunable hw.bus.devctl_disable has been superseded by 1376 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1377 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1378 is 1000. 1379 138020090813: 1381 Remove the option STOP_NMI. The default action is now to use NMI only 1382 for KDB via the newly introduced function stop_cpus_hard() and 1383 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1384 138520090803: 1386 The stable/8 branch created in subversion. This corresponds to the 1387 RELENG_8 branch in CVS. 1388 138920090719: 1390 Bump the shared library version numbers for all libraries that do not 1391 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1392 __FreeBSD_version to 800105. 1393 139420090714: 1395 Due to changes in the implementation of virtual network stack support, 1396 all network-related kernel modules must be recompiled. As this change 1397 breaks the ABI, bump __FreeBSD_version to 800104. 1398 139920090713: 1400 The TOE interface to the TCP syncache has been modified to remove 1401 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1402 The cxgb driver is the only TOE consumer affected by this change, and 1403 needs to be recompiled along with the kernel. As this change breaks 1404 the ABI, bump __FreeBSD_version to 800103. 1405 140620090712: 1407 Padding has been added to struct tcpcb, sackhint and tcpstat in 1408 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1409 maintaining the ABI. However, this change breaks the ABI, so bump 1410 __FreeBSD_version to 800102. User space tools that rely on the size of 1411 any of these structs (e.g. sockstat) need to be recompiled. 1412 141320090630: 1414 The NFS_LEGACYRPC option has been removed along with the old kernel 1415 RPC implementation that this option selected. Kernel configurations 1416 may need to be adjusted. 1417 141820090629: 1419 The network interface device nodes at /dev/net/<interface> have been 1420 removed. All ioctl operations can be performed the normal way using 1421 routing sockets. The kqueue functionality can generally be replaced 1422 with routing sockets. 1423 142420090628: 1425 The documentation from the FreeBSD Documentation Project (Handbook, 1426 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1427 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1428 142920090624: 1430 The ABI of various structures related to the SYSV IPC API have been 1431 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1432 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1433 800100. 1434 143520090622: 1436 Layout of struct vnet has changed as routing related variables were 1437 moved to their own Vimage module. Modules need to be recompiled. Bump 1438 __FreeBSD_version to 800099. 1439 144020090619: 1441 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1442 respectively. As long as no more than 16 groups per process are used, 1443 no changes should be visible. When more than 16 groups are used, old 1444 binaries may fail if they call getgroups() or getgrouplist() with 1445 statically sized storage. Recompiling will work around this, but 1446 applications should be modified to use dynamically allocated storage 1447 for group arrays as POSIX.1-2008 does not cap an implementation's 1448 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1449 1450 NFS and portalfs mounts may also be affected as the list of groups is 1451 truncated to 16. Users of NFS who use more than 16 groups, should 1452 take care that negative group permissions are not used on the exported 1453 file systems as they will not be reliable unless a GSSAPI based 1454 authentication method is used. 1455 145620090616: 1457 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1458 option compiles in the support for adaptive spinning for lockmgrs 1459 which want to enable it. The lockinit() function now accepts the flag 1460 LK_ADAPTIVE in order to make the lock object subject to adaptive 1461 spinning when both held in write and read mode. 1462 146320090613: 1464 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1465 changed. User applications that use this ioctl need to be rebuilt. 1466 146720090611: 1468 The layout of struct thread has changed. Kernel and modules need to 1469 be rebuilt. 1470 147120090608: 1472 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1473 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1474 147520090602: 1476 window(1) has been removed from the base system. It can now be 1477 installed from ports. The port is called misc/window. 1478 147920090601: 1480 The way we are storing and accessing `routing table' entries has 1481 changed. Programs reading the FIB, like netstat, need to be 1482 re-compiled. 1483 148420090601: 1485 A new netisr implementation has been added for FreeBSD 8. Network 1486 file system modules, such as igmp, ipdivert, and others, should be 1487 rebuilt. 1488 Bump __FreeBSD_version to 800096. 1489 149020090530: 1491 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1492 more valid. 1493 149420090530: 1495 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1496 Bump __FreeBSD_version to 800094. 1497 149820090529: 1499 Add mnt_xflag field to 'struct mount'. File system modules need to be 1500 rebuilt. 1501 Bump __FreeBSD_version to 800093. 1502 150320090528: 1504 The compiling option ADAPTIVE_SX has been retired while it has been 1505 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1506 The KPI for sx_init_flags() changes as accepting flags: 1507 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1508 been introduced in order to handle the reversed logic. 1509 Bump __FreeBSD_version to 800092. 1510 151120090527: 1512 Add support for hierarchical jails. Remove global securelevel. 1513 Bump __FreeBSD_version to 800091. 1514 151520090523: 1516 The layout of struct vnet_net has changed, therefore modules 1517 need to be rebuilt. 1518 Bump __FreeBSD_version to 800090. 1519 152020090523: 1521 The newly imported zic(8) produces a new format in the output. Please 1522 run tzsetup(8) to install the newly created data to /etc/localtime. 1523 152420090520: 1525 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1526 hw.usb.* and is now consistent again with previous releases. 1527 152820090520: 1529 802.11 monitor mode support was revised and driver api's were changed. 1530 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1531 of DLT_IEEE802_11. No user-visible data structures were changed but 1532 applications that use DLT_IEEE802_11 may require changes. 1533 Bump __FreeBSD_version to 800088. 1534 153520090430: 1536 The layout of the following structs has changed: sysctl_oid, 1537 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1538 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1539 panics may be experienced. World rebuild is required for 1540 correctly checking networking state from userland. 1541 Bump __FreeBSD_version to 800085. 1542 154320090429: 1544 MLDv2 and Source-Specific Multicast (SSM) have been merged 1545 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1546 The implementation of SSM within FreeBSD's IPv6 stack closely 1547 follows the IPv4 implementation. 1548 1549 For kernel developers: 1550 1551 * The most important changes are that the ip6_output() and 1552 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1553 and this lock has been downgraded to a non-recursive mutex. 1554 1555 * As with the changes to the IPv4 stack to support SSM, filtering 1556 of inbound multicast traffic must now be performed by transport 1557 protocols within the IPv6 stack. This does not apply to TCP and 1558 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1559 1560 * The KPIs used by IPv6 multicast are similar to those used by 1561 the IPv4 stack, with the following differences: 1562 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1563 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1564 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1565 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1566 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1567 for MLDv1 have an additional 'timer' argument which is used to 1568 jitter the initial membership report for the solicited-node 1569 multicast membership on-link. 1570 * This is not strictly needed for MLDv2, which already jitters 1571 its report transmissions. However, the 'timer' argument is 1572 preserved in case MLDv1 is active on the interface. 1573 1574 * The KAME linked-list based IPv6 membership implementation has 1575 been refactored to use a vector similar to that used by the IPv4 1576 stack. 1577 Code which maintains a list of its own multicast memberships 1578 internally, e.g. carp, has been updated to reflect the new 1579 semantics. 1580 1581 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1582 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1583 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1584 implementation constraint which needs to be addressed in HEAD. 1585 1586 For application developers: 1587 1588 * The changes are broadly similar to those made for the IPv4 1589 stack. 1590 1591 * The use of IPv4 and IPv6 multicast socket options on the same 1592 socket, using mapped addresses, HAS NOT been tested or supported. 1593 1594 * There are a number of issues with the implementation of various 1595 IPv6 multicast APIs which need to be resolved in the API surface 1596 before the implementation is fully compatible with KAME userland 1597 use, and these are mostly to do with interface index treatment. 1598 1599 * The literature available discusses the use of either the delta / ASM 1600 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1601 using setsourcefilter(3)/getsourcefilter(3). For more information 1602 please refer to RFC 3768, 'Socket Interface Extensions for 1603 Multicast Source Filters'. 1604 1605 * Applications which use the published RFC 3678 APIs should be fine. 1606 1607 For systems administrators: 1608 1609 * The mtest(8) utility has been refactored to support IPv6, in 1610 addition to IPv4. Interface addresses are no longer accepted 1611 as arguments, their names must be used instead. The utility 1612 will map the interface name to its first IPv4 address as 1613 returned by getifaddrs(3). 1614 1615 * The ifmcstat(8) utility has also been updated to print the MLDv2 1616 endpoint state and source filter lists via sysctl(3). 1617 1618 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1619 loopback of IPv6 multicast datagrams by default; it defaults to 1 1620 to preserve the existing behaviour. Disabling multicast loopback is 1621 recommended for optimal system performance. 1622 1623 * The IPv6 MROUTING code has been changed to examine this sysctl 1624 instead of attempting to perform a group lookup before looping 1625 back forwarded datagrams. 1626 1627 Bump __FreeBSD_version to 800084. 1628 162920090422: 1630 Implement low-level Bluetooth HCI API. 1631 Bump __FreeBSD_version to 800083. 1632 163320090419: 1634 The layout of struct malloc_type, used by modules to register new 1635 memory allocation types, has changed. Most modules will need to 1636 be rebuilt or panics may be experienced. 1637 Bump __FreeBSD_version to 800081. 1638 163920090415: 1640 Anticipate overflowing inp_flags - add inp_flags2. 1641 This changes most offsets in inpcb, so checking v4 connection 1642 state will require a world rebuild. 1643 Bump __FreeBSD_version to 800080. 1644 164520090415: 1646 Add an llentry to struct route and struct route_in6. Modules 1647 embedding a struct route will need to be recompiled. 1648 Bump __FreeBSD_version to 800079. 1649 165020090414: 1651 The size of rt_metrics_lite and by extension rtentry has changed. 1652 Networking administration apps will need to be recompiled. 1653 The route command now supports show as an alias for get, weighting 1654 of routes, sticky and nostick flags to alter the behavior of stateful 1655 load balancing. 1656 Bump __FreeBSD_version to 800078. 1657 165820090408: 1659 Do not use Giant for kbdmux(4) locking. This is wrong and 1660 apparently causing more problems than it solves. This will 1661 re-open the issue where interrupt handlers may race with 1662 kbdmux(4) in polling mode. Typical symptoms include (but 1663 not limited to) duplicated and/or missing characters when 1664 low level console functions (such as gets) are used while 1665 interrupts are enabled (for example geli password prompt, 1666 mountroot prompt etc.). Disabling kbdmux(4) may help. 1667 166820090407: 1669 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1670 kernel modules referencing any of the above need to be recompiled. 1671 Bump __FreeBSD_version to 800075. 1672 167320090320: 1674 GEOM_PART has become the default partition slicer for storage devices, 1675 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1676 introduces some changes: 1677 1678 MSDOS/EBR: the devices created from MSDOS extended partition entries 1679 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1680 to devices with offset-based names. fstabs may need to be modified. 1681 1682 BSD: the "geometry does not match label" warning is harmless in most 1683 cases but it points to problems in file system misalignment with 1684 disk geometry. The "c" partition is now implicit, covers the whole 1685 top-level drive and cannot be (mis)used by users. 1686 1687 General: Kernel dumps are now not allowed to be written to devices 1688 whose partition types indicate they are meant to be used for file 1689 systems (or, in case of MSDOS partitions, as something else than 1690 the "386BSD" type). 1691 1692 Most of these changes date approximately from 200812. 1693 169420090319: 1695 The uscanner(4) driver has been removed from the kernel. This follows 1696 Linux removing theirs in 2.6 and making libusb the default interface 1697 (supported by sane). 1698 169920090319: 1700 The multicast forwarding code has been cleaned up. netstat(1) 1701 only relies on KVM now for printing bandwidth upcall meters. 1702 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1703 ip6_mroute_mod respectively. The config(5) options for statically 1704 compiling this code remain the same, i.e. 'options MROUTING'. 1705 170620090315: 1707 Support for the IFF_NEEDSGIANT network interface flag has been 1708 removed, which means that non-MPSAFE network device drivers are no 1709 longer supported. In particular, if_ar, if_sr, and network device 1710 drivers from the old (legacy) USB stack can no longer be built or 1711 used. 1712 171320090313: 1714 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1715 a bunch of new language catalog files have also been added. 1716 This means that some common libc messages are now localized and 1717 they depend on the LC_MESSAGES environmental variable. 1718 171920090313: 1720 The k8temp(4) driver has been renamed to amdtemp(4) since 1721 support for Family 10 and Family 11 CPU families was added. 1722 172320090309: 1724 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1725 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1726 1727 For kernel developers, the most important changes are that the 1728 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1729 and this lock has been downgraded to a non-recursive mutex. 1730 1731 Transport protocols (UDP, Raw IP) are now responsible for filtering 1732 inbound multicast traffic according to group membership and source 1733 filters. The imo_multicast_filter() KPI exists for this purpose. 1734 Transports which do not use multicast (SCTP, TCP) already reject 1735 multicast by default. Forwarding and receive performance may improve 1736 as a mutex acquisition is no longer needed in the ip_input() 1737 low-level input path. in_addmulti() and in_delmulti() are shimmed 1738 to new KPIs which exist to support SSM in-kernel. 1739 1740 For application developers, it is recommended that loopback of 1741 multicast datagrams be disabled for best performance, as this 1742 will still cause the lock to be taken for each looped-back 1743 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1744 be tuned to 0 to disable loopback by default; it defaults to 1 1745 to preserve the existing behaviour. 1746 1747 For systems administrators, to obtain best performance with 1748 multicast reception and multiple groups, it is always recommended 1749 that a card with a suitably precise hash filter is used. Hash 1750 collisions will still result in the lock being taken within the 1751 transport protocol input path to check group membership. 1752 1753 If deploying FreeBSD in an environment with IGMP snooping switches, 1754 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1755 enabled; this forces 224.0.0.0/24 group membership to be announced 1756 via IGMP. 1757 1758 The size of 'struct igmpstat' has changed; netstat needs to be 1759 recompiled to reflect this. 1760 Bump __FreeBSD_version to 800070. 1761 176220090309: 1763 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1764 updated to use it. This requires a buildworld/installworld in order to 1765 update the library and dependencies (usbconfig, etc). Its advisable to 1766 rebuild all ports which uses libusb. More specific directions are given 1767 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1768 libusb are no longer required and can be removed. 1769 177020090302: 1771 A workaround is committed to allow the creation of System V shared 1772 memory segment of size > 2 GB on the 64-bit architectures. 1773 Due to a limitation of the existing ABI, the shm_segsz member 1774 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1775 wrong for large segments. Note that limits must be explicitly 1776 raised to allow such segments to be created. 1777 177820090301: 1779 The layout of struct ifnet has changed, requiring a rebuild of all 1780 network device driver modules. 1781 178220090227: 1783 The /dev handling for the new USB stack has changed, a 1784 buildworld/installworld is required for libusb20. 1785 178620090223: 1787 The new USB2 stack has now been permanently moved in and all kernel and 1788 module names reverted to their previous values (eg, usb, ehci, ohci, 1789 ums, ...). The old usb stack can be compiled in by prefixing the name 1790 with the letter 'o', the old usb modules have been removed. 1791 Updating entry 20090216 for xorg and 20090215 for libmap may still 1792 apply. 1793 179420090217: 1795 The rc.conf(5) option if_up_delay has been renamed to 1796 defaultroute_delay to better reflect its purpose. If you have 1797 customized this setting in /etc/rc.conf you need to update it to 1798 use the new name. 1799 180020090216: 1801 xorg 7.4 wants to configure its input devices via hald which does not 1802 yet work with USB2. If the keyboard/mouse does not work in xorg then 1803 add 1804 Option "AllowEmptyInput" "off" 1805 to your ServerLayout section. This will cause X to use the configured 1806 kbd and mouse sections from your xorg.conf. 1807 180820090215: 1809 The GENERIC kernels for all architectures now default to the new USB2 1810 stack. No kernel config options or code have been removed so if a 1811 problem arises please report it and optionally revert to the old USB 1812 stack. If you are loading USB kernel modules or have a custom kernel 1813 that includes GENERIC then ensure that usb names are also changed over, 1814 eg uftdi -> usb2_serial_ftdi. 1815 1816 Older programs linked against the ports libusb 0.1 need to be 1817 redirected to the new stack's libusb20. /etc/libmap.conf can 1818 be used for this: 1819 # Map old usb library to new one for usb2 stack 1820 libusb-0.1.so.8 libusb20.so.1 1821 182220090209: 1823 All USB ethernet devices now attach as interfaces under the name ueN 1824 (eg. ue0). This is to provide a predictable name as vendors often 1825 change usb chipsets in a product without notice. 1826 182720090203: 1828 The ichsmb(4) driver has been changed to require SMBus slave 1829 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1830 All of the other SMBus controller drivers require left-justified 1831 slave addresses, so this change makes all the drivers provide the 1832 same interface. 1833 183420090201: 1835 INET6 statistics (struct ip6stat) was updated. 1836 netstat(1) needs to be recompiled. 1837 183820090119: 1839 NTFS has been removed from GENERIC kernel on amd64 to match 1840 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1841 will load ntfs.ko module automatically when NTFS support is 1842 actually needed, unless ntfs.ko is not installed or security 1843 level prohibits loading kernel modules. If either is the case, 1844 "options NTFS" has to be added into kernel config. 1845 184620090115: 1847 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1848 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1849 800061. User space tools that rely on the size of struct tcpcb in 1850 tcp_var.h (e.g. sockstat) need to be recompiled. 1851 185220081225: 1853 ng_tty(4) module updated to match the new TTY subsystem. 1854 Due to API change, user-level applications must be updated. 1855 New API support added to mpd5 CVS and expected to be present 1856 in next mpd5.3 release. 1857 185820081219: 1859 With __FreeBSD_version 800060 the makefs tool is part of 1860 the base system (it was a port). 1861 186220081216: 1863 The afdata and ifnet locks have been changed from mutexes to 1864 rwlocks, network modules will need to be re-compiled. 1865 186620081214: 1867 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1868 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1869 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1870 architecture and 40 bytes on 64-bit architecture. The userland 1871 applications "arp" and "ndp" have been updated accordingly. 1872 The output from "netstat -r" shows only routing entries and 1873 none of the L2 information. 1874 187520081130: 1876 __FreeBSD_version 800057 marks the switchover from the 1877 binary ath hal to source code. Users must add the line: 1878 1879 options AH_SUPPORT_AR5416 1880 1881 to their kernel config files when specifying: 1882 1883 device ath_hal 1884 1885 The ath_hal module no longer exists; the code is now compiled 1886 together with the driver in the ath module. It is now 1887 possible to tailor chip support (i.e. reduce the set of chips 1888 and thereby the code size); consult ath_hal(4) for details. 1889 189020081121: 1891 __FreeBSD_version 800054 adds memory barriers to 1892 <machine/atomic.h>, new interfaces to ifnet to facilitate 1893 multiple hardware transmit queues for cards that support 1894 them, and a lock-less ring-buffer implementation to 1895 enable drivers to more efficiently manage queueing of 1896 packets. 1897 189820081117: 1899 A new version of ZFS (version 13) has been merged to -HEAD. 1900 This version has zpool attribute "listsnapshots" off by 1901 default, which means "zfs list" does not show snapshots, 1902 and is the same as Solaris behavior. 1903 190420081028: 1905 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1906 190720081009: 1908 The uhci, ohci, ehci and slhci USB Host controller drivers have 1909 been put into separate modules. If you load the usb module 1910 separately through loader.conf you will need to load the 1911 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1912 controller add the following to loader.conf: 1913 1914 uhci_load="YES" 1915 ehci_load="YES" 1916 191720081009: 1918 The ABI used by the PMC toolset has changed. Please keep 1919 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1920 sync. 1921 192220081009: 1923 atapci kernel module now includes only generic PCI ATA 1924 driver. AHCI driver moved to ataahci kernel module. 1925 All vendor-specific code moved into separate kernel modules: 1926 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1927 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1928 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1929 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1930 193120080820: 1932 The TTY subsystem of the kernel has been replaced by a new 1933 implementation, which provides better scalability and an 1934 improved driver model. Most common drivers have been migrated to 1935 the new TTY subsystem, while others have not. The following 1936 drivers have not yet been ported to the new TTY layer: 1937 1938 PCI/ISA: 1939 cy, digi, rc, rp, sio 1940 1941 USB: 1942 ubser, ucycom 1943 1944 Line disciplines: 1945 ng_h4, ng_tty, ppp, sl, snp 1946 1947 Adding these drivers to your kernel configuration file shall 1948 cause compilation to fail. 1949 195020080818: 1951 ntpd has been upgraded to 4.2.4p5. 1952 195320080801: 1954 OpenSSH has been upgraded to 5.1p1. 1955 1956 For many years, FreeBSD's version of OpenSSH preferred DSA 1957 over RSA for host and user authentication keys. With this 1958 upgrade, we've switched to the vendor's default of RSA over 1959 DSA. This may cause upgraded clients to warn about unknown 1960 host keys even for previously known hosts. Users should 1961 follow the usual procedure for verifying host keys before 1962 accepting the RSA key. 1963 1964 This can be circumvented by setting the "HostKeyAlgorithms" 1965 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1966 command line. 1967 1968 Please note that the sequence of keys offered for 1969 authentication has been changed as well. You may want to 1970 specify IdentityFile in a different order to revert this 1971 behavior. 1972 197320080713: 1974 The sio(4) driver has been removed from the i386 and amd64 1975 kernel configuration files. This means uart(4) is now the 1976 default serial port driver on those platforms as well. 1977 1978 To prevent collisions with the sio(4) driver, the uart(4) driver 1979 uses different names for its device nodes. This means the 1980 onboard serial port will now most likely be called "ttyu0" 1981 instead of "ttyd0". You may need to reconfigure applications to 1982 use the new device names. 1983 1984 When using the serial port as a boot console, be sure to update 1985 /boot/device.hints and /etc/ttys before booting the new kernel. 1986 If you forget to do so, you can still manually specify the hints 1987 at the loader prompt: 1988 1989 set hint.uart.0.at="isa" 1990 set hint.uart.0.port="0x3F8" 1991 set hint.uart.0.flags="0x10" 1992 set hint.uart.0.irq="4" 1993 boot -s 1994 199520080609: 1996 The gpt(8) utility has been removed. Use gpart(8) to partition 1997 disks instead. 1998 199920080603: 2000 The version that Linuxulator emulates was changed from 2.4.2 2001 to 2.6.16. If you experience any problems with Linux binaries 2002 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2003 if it fixes the problem contact emulation mailing list. 2004 200520080525: 2006 ISDN4BSD (I4B) was removed from the src tree. You may need to 2007 update a your kernel configuration and remove relevant entries. 2008 200920080509: 2010 I have checked in code to support multiple routing tables. 2011 See the man pages setfib(1) and setfib(2). 2012 This is a hopefully backwards compatible version, 2013 but to make use of it you need to compile your kernel 2014 with options ROUTETABLES=2 (or more up to 16). 2015 201620080420: 2017 The 802.11 wireless support was redone to enable multi-bss 2018 operation on devices that are capable. The underlying device 2019 is no longer used directly but instead wlanX devices are 2020 cloned with ifconfig. This requires changes to rc.conf files. 2021 For example, change: 2022 ifconfig_ath0="WPA DHCP" 2023 to 2024 wlans_ath0=wlan0 2025 ifconfig_wlan0="WPA DHCP" 2026 see rc.conf(5) for more details. In addition, mergemaster of 2027 /etc/rc.d is highly recommended. Simultaneous update of userland 2028 and kernel wouldn't hurt either. 2029 2030 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2031 modules were merged into the base wlan module. All references 2032 to these modules (e.g. in kernel config files) must be removed. 2033 203420080408: 2035 psm(4) has gained write(2) support in native operation level. 2036 Arbitrary commands can be written to /dev/psm%d and status can 2037 be read back from it. Therefore, an application is responsible 2038 for status validation and error recovery. It is a no-op in 2039 other operation levels. 2040 204120080312: 2042 Support for KSE threading has been removed from the kernel. To 2043 run legacy applications linked against KSE libmap.conf may 2044 be used. The following libmap.conf may be used to ensure 2045 compatibility with any prior release: 2046 2047 libpthread.so.1 libthr.so.1 2048 libpthread.so.2 libthr.so.2 2049 libkse.so.3 libthr.so.3 2050 205120080301: 2052 The layout of struct vmspace has changed. This affects libkvm 2053 and any executables that link against libkvm and use the 2054 kvm_getprocs() function. In particular, but not exclusively, 2055 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2056 The effects are minimal, but it's advisable to upgrade world 2057 nonetheless. 2058 205920080229: 2060 The latest em driver no longer has support in it for the 2061 82575 adapter, this is now moved to the igb driver. The 2062 split was done to make new features that are incompatible 2063 with older hardware easier to do. 2064 206520080220: 2066 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2067 likewise the kernel option is now GEOM_LINUX_LVM. 2068 206920080211: 2070 The default NFS mount mode has changed from UDP to TCP for 2071 increased reliability. If you rely on (insecurely) NFS 2072 mounting across a firewall you may need to update your 2073 firewall rules. 2074 207520080208: 2076 Belatedly note the addition of m_collapse for compacting 2077 mbuf chains. 2078 207920080126: 2080 The fts(3) structures have been changed to use adequate 2081 integer types for their members and so to be able to cope 2082 with huge file trees. The old fts(3) ABI is preserved 2083 through symbol versioning in libc, so third-party binaries 2084 using fts(3) should still work, although they will not take 2085 advantage of the extended types. At the same time, some 2086 third-party software might fail to build after this change 2087 due to unportable assumptions made in its source code about 2088 fts(3) structure members. Such software should be fixed 2089 by its vendor or, in the worst case, in the ports tree. 2090 FreeBSD_version 800015 marks this change for the unlikely 2091 case that a portable fix is impossible. 2092 209320080123: 2094 To upgrade to -current after this date, you must be running 2095 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2096 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2097 209820071128: 2099 The ADAPTIVE_GIANT kernel option has been retired because its 2100 functionality is the default now. 2101 210220071118: 2103 The AT keyboard emulation of sunkbd(4) has been turned on 2104 by default. In order to make the special symbols of the Sun 2105 keyboards driven by sunkbd(4) work under X these now have 2106 to be configured the same way as Sun USB keyboards driven 2107 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2108 2109 Option "XkbLayout" "us" 2110 Option "XkbRules" "xorg" 2111 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2112 211320071024: 2114 It has been decided that it is desirable to provide ABI 2115 backwards compatibility to the FreeBSD 4/5/6 versions of the 2116 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2117 broken with the introduction of PCI domain support (see the 2118 20070930 entry). Unfortunately, this required the ABI of 2119 PCIOCGETCONF to be broken again in order to be able to 2120 provide backwards compatibility to the old version of that 2121 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2122 again. As for prominent ports this affects neither pciutils 2123 nor xorg-server this time, the hal port needs to be rebuilt 2124 however. 2125 212620071020: 2127 The misnamed kthread_create() and friends have been renamed 2128 to kproc_create() etc. Many of the callers already 2129 used kproc_start().. 2130 I will return kthread_create() and friends in a while 2131 with implementations that actually create threads, not procs. 2132 Renaming corresponds with version 800002. 2133 213420071010: 2135 RELENG_7 branched. 2136 2137COMMON ITEMS: 2138 2139 General Notes 2140 ------------- 2141 Avoid using make -j when upgrading. While generally safe, there are 2142 sometimes problems using -j to upgrade. If your upgrade fails with 2143 -j, please try again without -j. From time to time in the past there 2144 have been problems using -j with buildworld and/or installworld. This 2145 is especially true when upgrading between "distant" versions (eg one 2146 that cross a major release boundary or several minor releases, or when 2147 several months have passed on the -current branch). 2148 2149 Sometimes, obscure build problems are the result of environment 2150 poisoning. This can happen because the make utility reads its 2151 environment when searching for values for global variables. To run 2152 your build attempts in an "environmental clean room", prefix all make 2153 commands with 'env -i '. See the env(1) manual page for more details. 2154 2155 When upgrading from one major version to another it is generally best 2156 to upgrade to the latest code in the currently installed branch first, 2157 then do an upgrade to the new branch. This is the best-tested upgrade 2158 path, and has the highest probability of being successful. Please try 2159 this approach before reporting problems with a major version upgrade. 2160 2161 When upgrading a live system, having a root shell around before 2162 installing anything can help undo problems. Not having a root shell 2163 around can lead to problems if pam has changed too much from your 2164 starting point to allow continued authentication after the upgrade. 2165 2166 ZFS notes 2167 --------- 2168 When upgrading the boot ZFS pool to a new version, always follow 2169 these two steps: 2170 2171 1.) recompile and reinstall the ZFS boot loader and boot block 2172 (this is part of "make buildworld" and "make installworld") 2173 2174 2.) update the ZFS boot block on your boot drive 2175 2176 The following example updates the ZFS boot block on the first 2177 partition (freebsd-boot) of a GPT partitioned drive ad0: 2178 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2179 2180 Non-boot pools do not need these updates. 2181 2182 To build a kernel 2183 ----------------- 2184 If you are updating from a prior version of FreeBSD (even one just 2185 a few days old), you should follow this procedure. It is the most 2186 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2187 2188 make kernel-toolchain 2189 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2190 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2191 2192 To test a kernel once 2193 --------------------- 2194 If you just want to boot a kernel once (because you are not sure 2195 if it works, or if you want to boot a known bad kernel to provide 2196 debugging information) run 2197 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2198 nextboot -k testkernel 2199 2200 To just build a kernel when you know that it won't mess you up 2201 -------------------------------------------------------------- 2202 This assumes you are already running a CURRENT system. Replace 2203 ${arch} with the architecture of your machine (e.g. "i386", 2204 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2205 2206 cd src/sys/${arch}/conf 2207 config KERNEL_NAME_HERE 2208 cd ../compile/KERNEL_NAME_HERE 2209 make depend 2210 make 2211 make install 2212 2213 If this fails, go to the "To build a kernel" section. 2214 2215 To rebuild everything and install it on the current system. 2216 ----------------------------------------------------------- 2217 # Note: sometimes if you are running current you gotta do more than 2218 # is listed here if you are upgrading from a really old current. 2219 2220 <make sure you have good level 0 dumps> 2221 make buildworld 2222 make kernel KERNCONF=YOUR_KERNEL_HERE 2223 [1] 2224 <reboot in single user> [3] 2225 mergemaster -p [5] 2226 make installworld 2227 mergemaster -i [4] 2228 make delete-old [6] 2229 <reboot> 2230 2231 To cross-install current onto a separate partition 2232 -------------------------------------------------- 2233 # In this approach we use a separate partition to hold 2234 # current's root, 'usr', and 'var' directories. A partition 2235 # holding "/", "/usr" and "/var" should be about 2GB in 2236 # size. 2237 2238 <make sure you have good level 0 dumps> 2239 <boot into -stable> 2240 make buildworld 2241 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2242 <maybe newfs current's root partition> 2243 <mount current's root partition on directory ${CURRENT_ROOT}> 2244 make installworld DESTDIR=${CURRENT_ROOT} 2245 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2246 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2247 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2248 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2249 <reboot into current> 2250 <do a "native" rebuild/install as described in the previous section> 2251 <maybe install compatibility libraries from ports/misc/compat*> 2252 <reboot> 2253 2254 2255 To upgrade in-place from stable to current 2256 ---------------------------------------------- 2257 <make sure you have good level 0 dumps> 2258 make buildworld [9] 2259 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2260 [1] 2261 <reboot in single user> [3] 2262 mergemaster -p [5] 2263 make installworld 2264 mergemaster -i [4] 2265 make delete-old [6] 2266 <reboot> 2267 2268 Make sure that you've read the UPDATING file to understand the 2269 tweaks to various things you need. At this point in the life 2270 cycle of current, things change often and you are on your own 2271 to cope. The defaults can also change, so please read ALL of 2272 the UPDATING entries. 2273 2274 Also, if you are tracking -current, you must be subscribed to 2275 freebsd-current@freebsd.org. Make sure that before you update 2276 your sources that you have read and understood all the recent 2277 messages there. If in doubt, please track -stable which has 2278 much fewer pitfalls. 2279 2280 [1] If you have third party modules, such as vmware, you 2281 should disable them at this point so they don't crash your 2282 system on reboot. 2283 2284 [3] From the bootblocks, boot -s, and then do 2285 fsck -p 2286 mount -u / 2287 mount -a 2288 cd src 2289 adjkerntz -i # if CMOS is wall time 2290 Also, when doing a major release upgrade, it is required that 2291 you boot into single user mode to do the installworld. 2292 2293 [4] Note: This step is non-optional. Failure to do this step 2294 can result in a significant reduction in the functionality of the 2295 system. Attempting to do it by hand is not recommended and those 2296 that pursue this avenue should read this file carefully, as well 2297 as the archives of freebsd-current and freebsd-hackers mailing lists 2298 for potential gotchas. The -U option is also useful to consider. 2299 See mergemaster(8) for more information. 2300 2301 [5] Usually this step is a noop. However, from time to time 2302 you may need to do this if you get unknown user in the following 2303 step. It never hurts to do it all the time. You may need to 2304 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2305 install) after the buildworld before this step if you last updated 2306 from current before 20130425 or from -stable before 20130430. 2307 2308 [6] This only deletes old files and directories. Old libraries 2309 can be deleted by "make delete-old-libs", but you have to make 2310 sure that no program is using those libraries anymore. 2311 2312 [8] In order to have a kernel that can run the 4.x binaries needed to 2313 do an installworld, you must include the COMPAT_FREEBSD4 option in 2314 your kernel. Failure to do so may leave you with a system that is 2315 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2316 required to run the 5.x binaries on more recent kernels. And so on 2317 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2318 2319 Make sure that you merge any new devices from GENERIC since the 2320 last time you updated your kernel config file. 2321 2322 [9] When checking out sources, you must include the -P flag to have 2323 cvs prune empty directories. 2324 2325 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2326 "?=" instead of the "=" assignment operator, so that buildworld can 2327 override the CPUTYPE if it needs to. 2328 2329 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2330 not on the command line, or in /etc/make.conf. buildworld will 2331 warn if it is improperly defined. 2332FORMAT: 2333 2334This file contains a list, in reverse chronological order, of major 2335breakages in tracking -current. It is not guaranteed to be a complete 2336list of such breakages, and only contains entries since October 10, 2007. 2337If you need to see UPDATING entries from before that date, you will need 2338to fetch an UPDATING file from an older FreeBSD release. 2339 2340Copyright information: 2341 2342Copyright 1998-2009 M.
