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 1920160114 p27 FreeBSD-SA-16:07.openssh 20 21 Fix OpenSSH client information leak.

New NTP version is 4.2.8p4. 60 61 The configuration file syntax has been changed, thus mergemaster 62 run is recommended. Now the "kod" parameter requires "limited" 63 parameter. If the ntp.conf is not updated, the ntpd will run 64 successfully, but with KoD disabled. 65 6620151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 67 Revised patch to address a regression that prevents NIS from working. 68 6920150929: p21 FreeBSD-SA-15:24.rpcbind 70 71 Fix rpcbind(8) remote denial of service.

[SA-15:02] 190 191 Fix SCTP stream reset vulnerability. [SA-15:03] 192 19320150114: p4 FreeBSD-SA-15:01.openssl 194 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 195 19620141223: p3 FreeBSD-SA-14:31.ntp 197 FreeBSD-EN-14:13.freebsd-update 198 199 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 200 Fix directory deletion issue in freebsd-update. [EN-14:13] 201 20220141217: p2 FreeBSD-SA-14:30.unbound 203 Fix unbound remote denial of service vulnerability. 204 20520141210: p1 FreeBSD-SA-14:27.stdio 206 FreeBSD-SA-14:28.file 207 208 Fix buffer overflow in stdio. [SA-14:27] 209 210 Fix multiple vulnerabilities in file(1) and libmagic(3). 211 [SA-14:28] 212 21320140904: 214 The ofwfb driver, used to provide a graphics console on PowerPC when 215 using vt(4), no longer allows mmap() of all of physical memory. This 216 will prevent Xorg on PowerPC with some ATI graphics cards from 217 initializing properly unless x11-servers/xorg-server is updated to 218 1.12.4_8 or newer. 219 22020140831: 221 The libatf-c and libatf-c++ major versions were downgraded to 0 and 222 1 respectively to match the upstream numbers. They were out of 223 sync because, when they were originally added to FreeBSD, the 224 upstream versions were not respected. These libraries are private 225 and not yet built by default, so renumbering them should be a 226 non-issue. However, unclean source trees will yield broken test 227 programs once the operator executes "make delete-old-libs" after a 228 "make installworld". 229 230 Additionally, the atf-sh binary was made private by moving it into 231 /usr/libexec/. Already-built shell test programs will keep the 232 path to the old binary so they will break after "make delete-old" 233 is run. 234 235 If you are using WITH_TESTS=yes (not the default), wipe the object 236 tree and rebuild from scratch to prevent spurious test failures. 237 This is only needed once: the misnumbered libraries and misplaced 238 binaries have been added to OptionalObsoleteFiles.inc so they will 239 be removed during a clean upgrade. 240 24120140814: 242 The ixgbe tunables now match their sysctl counterparts, for example: 243 hw.ixgbe.enable_aim => hw.ix.enable_aim 244 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 245 24620140801: 247 The NFSv4.1 server committed by r269398 changes the internal 248 function call interfaces used between the NFS and krpc modules. 249 As such, __FreeBSD_version was bumped. 250 25120140729: 252 The default unbound configuration has been modified to address 253 issues with reverse lookups on networks that use private 254 address ranges. If you use the local_unbound service, run 255 "service local_unbound setup" as root to regenerate your 256 configuration, then "service local_unbound reload" to load the 257 new configuration. 258 25920140717: 260 It is no longer necessary to include the dwarf version in your DEBUG 261 options in your kernel config file. The bug that required it to be 262 placed in the config file has bene fixed. DEBUG should now just 263 contain -g. The build system will automatically update things 264 to do the right thing. 265 26620140715: 267 Several ABI breaking changes were merged to CTL and new iSCSI code. 268 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 269 iscsictl need to be rebuilt to work with a new kernel. 270 27120140708: 272 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 273 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 274 which differs from the behaviour controlled by this knob.) 275 27620140608: 277 On i386 and amd64 systems, the onifconsole flag is now set by default 278 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 279 as a login TTY if it is set in the bootloader as an active kernel 280 console. No changes in behavior should result otherwise. To revert to 281 the previous behavior, set ttyu0 to "off" in /etc/ttys. 282 28320140512: 284 Clang and llvm have been upgraded to 3.4.1 release. 285 28620140321: 287 Clang and llvm have been upgraded to 3.4 release. 288 28920140306: 290 If a Makefile in a tests/ directory was auto-generating a Kyuafile 291 instead of providing an explicit one, this would prevent such 292 Makefile from providing its own Kyuafile in the future during 293 NO_CLEAN builds. This has been fixed in the Makefiles but manual 294 intervention is needed to clean an objdir if you use NO_CLEAN: 295 # find /usr/obj -name Kyuafile | xargs rm -f 296 29720140303: 298 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 299 capability mode support. Please note that enabling the feature in 300 kernel is still highly recommended. 301 30220140227: 303 OpenSSH is now built with sandbox support, and will use sandbox as 304 the default privilege separation method. This requires Capsicum 305 capability mode support in kernel. 306 30720140216: 308 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 309 been deprecated and will not be part of FreeBSD 11.0 and later 310 releases. If you use this driver, please consider switching to 311 the nfe(4) driver instead. 312 31320140120: 314 10.0-RELEASE. 315 31620131216: 317 The behavior of gss_pseudo_random() for the krb5 mechanism 318 has changed, for applications requesting a longer random string 319 than produced by the underlying enctype's pseudo-random() function. 320 In particular, the random string produced from a session key of 321 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 322 be different at the 17th octet and later, after this change. 323 The counter used in the PRF+ construction is now encoded as a 324 big-endian integer in accordance with RFC 4402. 325 __FreeBSD_version is bumped to 1000701. 326 32720131108: 328 The WITHOUT_ATF build knob has been removed and its functionality 329 has been subsumed into the more generic WITHOUT_TESTS. If you were 330 using the former to disable the build of the ATF libraries, you 331 should change your settings to use the latter. 332 33320131031: 334 The default version of mtree is nmtree which is obtained from 335 NetBSD. The output is generally the same, but may vary 336 slightly. If you found you need identical output adding 337 "-F freebsd9" to the command line should do the trick. For the 338 time being, the old mtree is available as fmtree. 339 34020131014: 341 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 342 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 343 1.1.4_8 and verify bsdyml not linked in, before running "make 344 delete-old-libs": 345 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 346 or 347 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 348 34920131010: 350 The rc.d/jail script has been updated to support jail(8) 351 configuration file. The "jail_<jname>_*" rc.conf(5) variables 352 for per-jail configuration are automatically converted to 353 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 354 This is transparently backward compatible. See below about some 355 incompatibilities and rc.conf(5) manual page for more details. 356 357 These variables are now deprecated in favor of jail(8) configuration 358 file. One can use "rc.d/jail config <jname>" command to generate 359 a jail(8) configuration file in /var/run/jail.<jname>.conf without 360 running the jail(8) utility. The default pathname of the 361 configuration file is /etc/jail.conf and can be specified by 362 using $jail_conf or $jail_<jname>_conf variables. 363 364 Please note that jail_devfs_ruleset accepts an integer at 365 this moment. Please consider to rewrite the ruleset name 366 with an integer. 367 36820130930: 369 BIND has been removed from the base system. If all you need 370 is a local resolver, simply enable and start the local_unbound 371 service instead. Otherwise, several versions of BIND are 372 available in the ports tree. The dns/bind99 port is one example. 373 374 With this change, nslookup(1) and dig(1) are no longer in the base 375 system. Users should instead use host(1) and drill(1) which are 376 in the base system. Alternatively, nslookup and dig can 377 be obtained by installing the dns/bind-tools port. 378 37920130916: 380 With the addition of unbound(8), a new unbound user is now 381 required during installworld. "mergemaster -p" can be used to 382 add the user prior to installworld, as documented in the handbook. 383 38420130911: 385 OpenSSH is now built with DNSSEC support, and will by default 386 silently trust signed SSHFP records. This can be controlled with 387 the VerifyHostKeyDNS client configuration setting. DNSSEC support 388 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 389 39020130906: 391 The GNU Compiler Collection and C++ standard library (libstdc++) 392 are no longer built by default on platforms where clang is the system 393 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 394 options in src.conf. 395 39620130905: 397 The PROCDESC kernel option is now part of the GENERIC kernel 398 configuration and is required for the rwhod(8) to work. 399 If you are using custom kernel configuration, you should include 400 'options PROCDESC'. 401 40220130905: 403 The API and ABI related to the Capsicum framework was modified 404 in backward incompatible way. The userland libraries and programs 405 have to be recompiled to work with the new kernel. This includes the 406 following libraries and programs, but the whole buildworld is 407 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 408 kdump, procstat, rwho, rwhod, uniq. 409 41020130903: 411 AES-NI intrinsic support has been added to gcc. The AES-NI module 412 has been updated to use this support. A new gcc is required to build 413 the aesni module on both i386 and amd64. 414 41520130821: 416 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 417 Thus "device padlock_rng" and "device rdrand_rng" should be 418 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 419 42020130813: 421 WITH_ICONV has been split into two feature sets. WITH_ICONV now 422 enables just the iconv* functionality and is now on by default. 423 WITH_LIBICONV_COMPAT enables the libiconv api and link time 424 compatability. Set WITHOUT_ICONV to build the old way. 425 If you have been using WITH_ICONV before, you will very likely 426 need to turn on WITH_LIBICONV_COMPAT. 427 42820130806: 429 INVARIANTS option now enables DEBUG for code with OpenSolaris and 430 Illumos origin, including ZFS. If you have INVARIANTS in your 431 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 432 explicitly. 433 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 434 locks if WITNESS option was set. Because that generated a lot of 435 witness(9) reports and all of them were believed to be false 436 positives, this is no longer done. New option OPENSOLARIS_WITNESS 437 can be used to achieve the previous behavior. 438 43920130806: 440 Timer values in IPv6 data structures now use time_uptime instead 441 of time_second. Although this is not a user-visible functional 442 change, userland utilities which directly use them---ndp(8), 443 rtadvd(8), and rtsold(8) in the base system---need to be updated 444 to r253970 or later. 445 44620130802: 447 find -delete can now delete the pathnames given as arguments, 448 instead of only files found below them or if the pathname did 449 not contain any slashes. Formerly, the following error message 450 would result: 451 452 find: -delete: <path>: relative path potentially not safe 453 454 Deleting the pathnames given as arguments can be prevented 455 without error messages using -mindepth 1 or by changing 456 directory and passing "." as argument to find. This works in the 457 old as well as the new version of find. 458 45920130726: 460 Behavior of devfs rules path matching has been changed. 461 Pattern is now always matched against fully qualified devfs 462 path and slash characters must be explicitly matched by 463 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 464 subdirectories must be reviewed. 465 46620130716: 467 The default ARM ABI has changed to the ARM EABI. The old ABI is 468 incompatible with the ARM EABI and all programs and modules will 469 need to be rebuilt to work with a new kernel. 470 471 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 472 473 NOTE: Support for the old ABI will be removed in the future and 474 users are advised to upgrade. 475 47620130709: 477 pkg_install has been disconnected from the build if you really need it 478 you should add WITH_PKGTOOLS in your src.conf(5). 479 48020130709: 481 Most of network statistics structures were changed to be able 482 keep 64-bits counters. Thus all tools, that work with networking 483 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 484 48520130629: 486 Fix targets that run multiple make's to use && rather than ; 487 so that subsequent steps depend on success of previous. 488 489 NOTE: if building 'universe' with -j* on stable/8 or stable/9 490 it would be better to start the build using bmake, to avoid 491 overloading the machine. 492 49320130618: 494 Fix a bug that allowed a tracing process (e.g. gdb) to write 495 to a memory-mapped file in the traced process's address space 496 even if neither the traced process nor the tracing process had 497 write access to that file. 498 49920130615: 500 CVS has been removed from the base system. An exact copy 501 of the code is available from the devel/cvs port. 502 50320130613: 504 Some people report the following error after the switch to bmake: 505 506 make: illegal option -- J 507 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 508 ... 509 *** [buildworld] Error code 2 510 511 this likely due to an old instance of make in 512 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 513 which src/Makefile will use that blindly, if it exists, so if 514 you see the above error: 515 516 rm -rf `make -V MAKEPATH` 517 518 should resolve it. 519 52020130516: 521 Use bmake by default. 522 Whereas before one could choose to build with bmake via 523 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 524 make. The goal is to remove these knobs for 10-RELEASE. 525 526 It is worth noting that bmake (like gmake) treats the command 527 line as the unit of failure, rather than statements within the 528 command line. Thus '(cd some/where && dosomething)' is safer 529 than 'cd some/where; dosomething'. The '()' allows consistent 530 behavior in parallel build. 531 53220130429: 533 Fix a bug that allows NFS clients to issue READDIR on files. 534 53520130426: 536 The WITHOUT_IDEA option has been removed because 537 the IDEA patent expired. 538 53920130426: 540 The sysctl which controls TRIM support under ZFS has been renamed 541 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 542 enabled by default. 543 54420130425: 545 The mergemaster command now uses the default MAKEOBJDIRPREFIX 546 rather than creating it's own in the temporary directory in 547 order allow access to bootstrapped versions of tools such as 548 install and mtree. When upgrading from version of FreeBSD where 549 the install command does not support -l, you will need to 550 install a new mergemaster command if mergemaster -p is required. 551 This can be accomplished with the command (cd src/usr.sbin/mergemaster 552 && make install). 553 55420130404: 555 Legacy ATA stack, disabled and replaced by new CAM-based one since 556 FreeBSD 9.0, completely removed from the sources. Kernel modules 557 atadisk and atapi*, user-level tools atacontrol and burncd are 558 removed. Kernel option `options ATA_CAM` is now permanently enabled 559 and removed. 560 56120130319: 562 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 563 and socketpair(2). Software, in particular Kerberos, may 564 automatically detect and use these during building. The resulting 565 binaries will not work on older kernels. 566 56720130308: 568 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 569 information, see the respective 20130304 entry). 570 57120130304: 572 Recent commits to callout(9) changed the size of struct callout, 573 so the KBI is probably heavily disturbed. Also, some functions 574 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 575 by macros. Every kernel module using it won't load, so rebuild 576 is requested. 577 578 The ctl device has been re-enabled in GENERIC for i386 and amd64, 579 but does not initialize by default (because of the new CTL_DISABLE 580 option) to save memory. To re-enable it, remove the CTL_DISABLE 581 option from the kernel config file or set kern.cam.ctl.disable=0 582 in /boot/loader.conf. 583 58420130301: 585 The ctl device has been disabled in GENERIC for i386 and amd64. 586 This was done due to the extra memory being allocated at system 587 initialisation time by the ctl driver which was only used if 588 a CAM target device was created. This makes a FreeBSD system 589 unusable on 128MB or less of RAM. 590 59120130208: 592 A new compression method (lz4) has been merged to -HEAD. Please 593 refer to zpool-features(7) for more information. 594 595 Please refer to the "ZFS notes" section of this file for information 596 on upgrading boot ZFS pools. 597 59820130129: 599 A BSD-licensed patch(1) variant has been added and is installed 600 as bsdpatch, being the GNU version the default patch. 601 To inverse the logic and use the BSD-licensed one as default, 602 while having the GNU version installed as gnupatch, rebuild 603 and install world with the WITH_BSD_PATCH knob set. 604 60520130121: 606 Due to the use of the new -l option to install(1) during build 607 and install, you must take care not to directly set the INSTALL 608 make variable in your /etc/make.conf, /etc/src.conf, or on the 609 command line. If you wish to use the -C flag for all installs 610 you may be able to add INSTALL+=-C to /etc/make.conf or 611 /etc/src.conf. 612 61320130118: 614 The install(1) option -M has changed meaning and now takes an 615 argument that is a file or path to append logs to. In the 616 unlikely event that -M was the last option on the command line 617 and the command line contained at least two files and a target 618 directory the first file will have logs appended to it. The -M 619 option served little practical purpose in the last decade so its 620 use is expected to be extremely rare. 621 62220121223: 623 After switching to Clang as the default compiler some users of ZFS 624 on i386 systems started to experience stack overflow kernel panics. 625 Please consider using 'options KSTACK_PAGES=4' in such configurations. 626 62720121222: 628 GEOM_LABEL now mangles label names read from file system metadata. 629 Mangling affect labels containing spaces, non-printable characters, 630 '%' or '"'. Device names in /etc/fstab and other places may need to 631 be updated. 632 63320121217: 634 By default, only the 10 most recent kernel dumps will be saved. To 635 restore the previous behaviour (no limit on the number of kernel dumps 636 stored in the dump directory) add the following line to /etc/rc.conf: 637 638 savecore_flags="" 639 64020121201: 641 With the addition of auditdistd(8), a new auditdistd user is now 642 required during installworld. "mergemaster -p" can be used to 643 add the user prior to installworld, as documented in the handbook. 644 64520121117: 646 The sin6_scope_id member variable in struct sockaddr_in6 is now 647 filled by the kernel before passing the structure to the userland via 648 sysctl or routing socket. This means the KAME-specific embedded scope 649 id in sin6_addr.s6_addr[2] is always cleared in userland application. 650 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 651 __FreeBSD_version is bumped to 1000025. 652 65320121105: 654 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 655 This means that the world and kernel will be compiled with clang 656 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 657 and /usr/bin/cpp. To disable this behavior and revert to building 658 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 659 of current may need to bootstrap WITHOUT_CLANG first if the clang 660 build fails (its compatibility window doesn't extend to the 9 stable 661 branch point). 662 66320121102: 664 The IPFIREWALL_FORWARD kernel option has been removed. Its 665 functionality now turned on by default. 666 66720121023: 668 The ZERO_COPY_SOCKET kernel option has been removed and 669 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 670 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 671 mechanism which is not safe and may result in kernel crashes. 672 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 673 driver supports disposeable external page sized mbuf storage. 674 Proper replacements for both zero-copy mechanisms are under 675 consideration and will eventually lead to complete removal 676 of the two kernel options. 677 67820121023: 679 The IPv4 network stack has been converted to network byte 680 order. The following modules need to be recompiled together 681 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 682 pf(4), ipfw(4), ng_ipfw(4), stf(4). 683 68420121022: 685 Support for non-MPSAFE filesystems was removed from VFS. The 686 VFS_VERSION was bumped, all filesystem modules shall be 687 recompiled. 688 68920121018: 690 All the non-MPSAFE filesystems have been disconnected from 691 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 692 portalfs, smbfs, xfs. 693 69420121016: 695 The interface cloning API and ABI has changed. The following 696 modules need to be recompiled together with kernel: 697 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 698 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 699 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 700 70120121015: 702 The sdhci driver was split in two parts: sdhci (generic SD Host 703 Controller logic) and sdhci_pci (actual hardware driver). 704 No kernel config modifications are required, but if you 705 load sdhc as a module you must switch to sdhci_pci instead. 706 70720121014: 708 Import the FUSE kernel and userland support into base system. 709 71020121013: 711 The GNU sort(1) program has been removed since the BSD-licensed 712 sort(1) has been the default for quite some time and no serious 713 problems have been reported. The corresponding WITH_GNU_SORT 714 knob has also gone. 715 71620121006: 717 The pfil(9) API/ABI for AF_INET family has been changed. Packet 718 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 719 with new kernel. 720 72120121001: 722 The net80211(4) ABI has been changed to allow for improved driver 723 PS-POLL and power-save support. All wireless drivers need to be 724 recompiled to work with the new kernel. 725 72620120913: 727 The random(4) support for the VIA hardware random number 728 generator (`PADLOCK') is no longer enabled unconditionally. 729 Add the padlock_rng device in the custom kernel config if 730 needed. The GENERIC kernels on i386 and amd64 do include the 731 device, so the change only affects the custom kernel 732 configurations. 733 73420120908: 735 The pf(4) packet filter ABI has been changed. pfctl(8) and 736 snmp_pf module need to be recompiled to work with new kernel. 737 73820120828: 739 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 740 to -HEAD. Pools that have empty_bpobj in active state can not be 741 imported read-write with ZFS implementations that do not support 742 this feature. For more information read the zpool-features(5) 743 manual page. 744 74520120727: 746 The sparc64 ZFS loader has been changed to no longer try to auto- 747 detect ZFS providers based on diskN aliases but now requires these 748 to be explicitly listed in the OFW boot-device environment variable. 749 75020120712: 751 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 752 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 753 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 754 75520120712: 756 The following sysctls and tunables have been renamed for consistency 757 with other variables: 758 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 759 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 760 76120120628: 762 The sort utility has been replaced with BSD sort. For now, GNU sort 763 is also available as "gnusort" or the default can be set back to 764 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 765 installed as "bsdsort". 766 76720120611: 768 A new version of ZFS (pool version 5000) has been merged to -HEAD. 769 Starting with this version the old system of ZFS pool versioning 770 is superseded by "feature flags". This concept enables forward 771 compatibility against certain future changes in functionality of ZFS 772 pools. The first read-only compatible "feature flag" for ZFS pools 773 is named "com.delphix:async_destroy". For more information 774 read the new zpool-features(5) manual page. 775 Please refer to the "ZFS notes" section of this file for information 776 on upgrading boot ZFS pools. 777 77820120417: 779 The malloc(3) implementation embedded in libc now uses sources imported 780 as contrib/jemalloc. The most disruptive API change is to 781 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 782 delete it prior to installworld, and optionally re-create it using the 783 new format after rebooting. See malloc.conf(5) for details 784 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 785 NAMESPACE section). 786 78720120328: 788 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 789 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 790 now spelled mips. This is to aid compatibility with third-party 791 software that expects this naming scheme in uname(3). Little-endian 792 settings are unchanged. If you are updating a big-endian mips64 machine 793 from before this change, you may need to set MACHINE_ARCH=mips64 in 794 your environment before the new build system will recognize your machine. 795 79620120306: 797 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 798 platforms. 799 80020120229: 801 Now unix domain sockets behave "as expected" on nullfs(5). Previously 802 nullfs(5) did not pass through all behaviours to the underlying layer, 803 as a result if we bound to a socket on the lower layer we could connect 804 only to the lower path; if we bound to the upper layer we could connect 805 only to the upper path. The new behavior is one can connect to both the 806 lower and the upper paths regardless what layer path one binds to. 807 80820120211: 809 The getifaddrs upgrade path broken with 20111215 has been restored. 810 If you have upgraded in between 20111215 and 20120209 you need to 811 recompile libc again with your kernel. You still need to recompile 812 world to be able to configure CARP but this restriction already 813 comes from 20111215. 814 81520120114: 816 The set_rcvar() function has been removed from /etc/rc.subr. All 817 base and ports rc.d scripts have been updated, so if you have a 818 port installed with a script in /usr/local/etc/rc.d you can either 819 hand-edit the rcvar= line, or reinstall the port. 820 821 An easy way to handle the mass-update of /etc/rc.d: 822 rm /etc/rc.d/* && mergemaster -i 823 82420120109: 825 panic(9) now stops other CPUs in the SMP systems, disables interrupts 826 on the current CPU and prevents other threads from running. 827 This behavior can be reverted using the kern.stop_scheduler_on_panic 828 tunable/sysctl. 829 The new behavior can be incompatible with kern.sync_on_panic. 830 83120111215: 832 The carp(4) facility has been changed significantly. Configuration 833 of the CARP protocol via ifconfig(8) has changed, as well as format 834 of CARP events submitted to devd(8) has changed. See manual pages 835 for more information. The arpbalance feature of carp(4) is currently 836 not supported anymore. 837 838 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 839 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 840 need to be recompiled. 841 84220111122: 843 The acpi_wmi(4) status device /dev/wmistat has been renamed to 844 /dev/wmistat0. 845 84620111108: 847 The option VFS_ALLOW_NONMPSAFE option has been added in order to 848 explicitely support non-MPSAFE filesystems. 849 It is on by default for all supported platform at this present 850 time. 851 85220111101: 853 The broken amd(4) driver has been replaced with esp(4) in the amd64, 854 i386 and pc98 GENERIC kernel configuration files. 855 85620110930: 857 sysinstall has been removed 858 85920110923: 860 The stable/9 branch created in subversion. This corresponds to the 861 RELENG_9 branch in CVS. 862 86320110913: 864 This commit modifies vfs_register() so that it uses a hash 865 calculation to set vfc_typenum, which is enabled by default. 866 The first time a system is booted after this change, the 867 vfc_typenum values will change for all file systems. The 868 main effect of this is a change to the NFS server file handles 869 for file systems that use vfc_typenum in their fsid, such as ZFS. 870 It will, however, prevent vfc_typenum from changing when file 871 systems are loaded in a different order for subsequent reboots. 872 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 873 until you are ready to remount all NFS clients after a reboot. 874 87520110828: 876 Bump the shared library version numbers for libraries that 877 do not use symbol versioning, have changed the ABI compared 878 to stable/8 and which shared library version was not bumped. 879 Done as part of 9.0-RELEASE cycle. 880 88120110815: 882 During the merge of Capsicum features, the fget(9) KPI was modified. 883 This may require the rebuilding of out-of-tree device drivers -- 884 issues have been reported specifically with the nVidia device driver. 885 __FreeBSD_version is bumped to 900041. 886 887 Also, there is a period between 20110811 and 20110814 where the 888 special devices /dev/{stdin,stdout,stderr} did not work correctly. 889 Building world from a kernel during that window may not work. 890 89120110628: 892 The packet filter (pf) code has been updated to OpenBSD 4.5. 893 You need to update userland tools to be in sync with kernel. 894 This update breaks backward compatibility with earlier pfsync(4) 895 versions. Care must be taken when updating redundant firewall setups. 896 89720110608: 898 The following sysctls and tunables are retired on x86 platforms: 899 machdep.hlt_cpus 900 machdep.hlt_logical_cpus 901 The following sysctl is retired: 902 machdep.hyperthreading_allowed 903 The sysctls were supposed to provide a way to dynamically offline and 904 online selected CPUs on x86 platforms, but the implementation has not 905 been reliable especially with SCHED_ULE scheduler. 906 machdep.hyperthreading_allowed tunable is still available to ignore 907 hyperthreading CPUs at OS level. 908 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 909 where X is an APIC ID of a CPU. Be advised, though, that disabling 910 CPUs in non-uniform fashion will result in non-uniform topology and 911 may lead to sub-optimal system performance with SCHED_ULE, which is 912 a default scheduler. 913 91420110607: 915 cpumask_t type is retired and cpuset_t is used in order to describe 916 a mask of CPUs. 917 91820110531: 919 Changes to ifconfig(8) for dynamic address family detection mandate 920 that you are running a kernel of 20110525 or later. Make sure to 921 follow the update procedure to boot a new kernel before installing 922 world. 923 92420110513: 925 Support for sun4v architecture is officially dropped 926 92720110503: 928 Several KPI breaking changes have been committed to the mii(4) layer, 929 the PHY drivers and consequently some Ethernet drivers using mii(4). 930 This means that miibus.ko and the modules of the affected Ethernet 931 drivers need to be recompiled. 932 933 Note to kernel developers: Given that the OUI bit reversion problem 934 was fixed as part of these changes all mii(4) commits related to OUIs, 935 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 936 handling, no longer can be merged verbatim to stable/8 and previous 937 branches. 938 93920110430: 940 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 941 into their kernel configurations along with 'device pci'. 942 94320110427: 944 The default NFS client is now the new NFS client, so fstype "newnfs" 945 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 946 Although mounts via fstype "nfs" will usually work without userland 947 changes, it is recommended that the mount(8) and mount_nfs(8) 948 commands be rebuilt from sources and that a link to mount_nfs called 949 mount_oldnfs be created. The new client is compiled into the 950 kernel with "options NFSCL" and this is needed for diskless root 951 file systems. The GENERIC kernel configs have been changed to use 952 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 953 To use the regular/old client, you can "mount -t oldnfs ...". For 954 a diskless root file system, you must also include a line like: 955 956 vfs.root.mountfrom="oldnfs:" 957 958 in the boot/loader.conf on the root fs on the NFS server to make 959 a diskless root fs use the old client. 960 96120110424: 962 The GENERIC kernels for all architectures now default to the new 963 CAM-based ATA stack. It means that all legacy ATA drivers were 964 removed and replaced by respective CAM drivers. If you are using 965 ATA device names in /etc/fstab or other places, make sure to update 966 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 967 where 'Y's are the sequential numbers starting from zero for each type 968 in order of detection, unless configured otherwise with tunables, 969 see cam(4)). There will be symbolic links created in /dev/ to map 970 old adX devices to the respective adaY. They should provide basic 971 compatibility for file systems mounting in most cases, but they do 972 not support old user-level APIs and do not have respective providers 973 in GEOM. Consider using updated management tools with new device names. 974 975 It is possible to load devices ahci, ata, siis and mvs as modules, 976 but option ATA_CAM should remain in kernel configuration to make ata 977 module work as CAM driver supporting legacy ATA controllers. Device ata 978 still can be used in modular fashion (atacore + ...). Modules atadisk 979 and atapi* are not used and won't affect operation in ATA_CAM mode. 980 Note that to use CAM-based ATA kernel should include CAM devices 981 scbus, pass, da (or explicitly ada), cd and optionally others. All of 982 them are parts of the cam module. 983 984 ataraid(4) functionality is now supported by the RAID GEOM class. 985 To use it you can load geom_raid kernel module and use graid(8) tool 986 for management. Instead of /dev/arX device names, use /dev/raid/rX. 987 988 No kernel config options or code have been removed, so if a problem 989 arises, please report it and optionally revert to the old ATA stack. 990 In order to do it you can remove from the kernel config: 991 options ATA_CAM 992 device ahci 993 device mvs 994 device siis 995 , and instead add back: 996 device atadisk # ATA disk drives 997 device ataraid # ATA RAID drives 998 device atapicd # ATAPI CDROM drives 999 device atapifd # ATAPI floppy drives 1000 device atapist # ATAPI tape drives 1001 100220110423: 1003 The default NFS server has been changed to the new server, which 1004 was referred to as the experimental server. If you need to switch 1005 back to the old NFS server, you must now put the "-o" option on 1006 both the mountd and nfsd commands. This can be done using the 1007 mountd_flags and nfs_server_flags rc.conf variables until an 1008 update to the rc scripts is committed, which is coming soon. 1009 101020110418: 1011 The GNU Objective-C runtime library (libobjc), and other Objective-C 1012 related components have been removed from the base system. If you 1013 require an Objective-C library, please use one of the available ports. 1014 101520110331: 1016 ath(4) has been split into bus- and device- modules. if_ath contains 1017 the HAL, the TX rate control and the network device code. if_ath_pci 1018 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1019 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1020 in order to use ath on everything else. 1021 1022 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1023 need to load if_ath and if_ath_pci for ath(4) operation. 1024 102520110314: 1026 As part of the replacement of sysinstall, the process of building 1027 release media has changed significantly. For details, please re-read 1028 release(7), which has been updated to reflect the new build process. 1029 103020110218: 1031 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1032 is the last available version under GPLv2. It brings a number of new 1033 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1034 4.1 and SSE 4.2), better support for powerpc64, a number of new 1035 directives, and lots of other small improvements. See the ChangeLog 1036 file in contrib/binutils for the full details. 1037 103820110218: 1039 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1040 compliant, and will now use half of hash for authentication. 1041 This will break interoperability with all stacks (including all 1042 actual FreeBSD versions) who implement 1043 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1044 authentication). 1045 The only workaround with such peers is to use another HMAC 1046 algorithm for IPsec ("phase 2") authentication. 1047 104820110207: 1049 Remove the uio_yield prototype and symbol. This function has 1050 been misnamed since it was introduced and should not be 1051 globally exposed with this name. The equivalent functionality 1052 is now available using kern_yield(curthread->td_user_pri). 1053 The function remains undocumented. 1054 105520110112: 1056 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1057 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1058 for scalar sysctls is defined but disabled. Code that needs 1059 UQUAD to pass the type checking that must compile on older 1060 systems where the define is not present can check against 1061 __FreeBSD_version >= 900030. 1062 1063 The system dialog(1) has been replaced with a new version previously 1064 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1065 with the previous version, but the libdialog associated with it has 1066 a largely incompatible API. As such, the original version of libdialog 1067 will be kept temporarily as libodialog, until its base system consumers 1068 are replaced or updated. Bump __FreeBSD_version to 900030. 1069 107020110103: 1071 If you are trying to run make universe on a -stable system, and you get 1072 the following warning: 1073 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1074 unknown. config(8) likely too old." 1075 or something similar to it, then you must upgrade your -stable system 1076 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1077 stable/8) or build the config from the latest stable/8 branch and 1078 install it on your system. 1079 1080 Prior to this date, building a current universe on 8-stable system from 1081 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1082 error in the first kernel build phase. A new config on those old 1083 systems will fix that problem for older versions of -current. 1084 108520101228: 1086 The TCP stack has been modified to allow Khelp modules to interact with 1087 it via helper hook points and store per-connection data in the TCP 1088 control block. Bump __FreeBSD_version to 900029. User space tools that 1089 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1090 be recompiled. 1091 109220101114: 1093 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1094 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1095 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1096 to take advantage of it instead of using custom implementations. This 1097 means that these drivers now no longer unconditionally advertise 1098 support for flow control but only do so if flow control is a selected 1099 media option. This was implemented in the generic support that way in 1100 order to allow flow control to be switched on and off via ifconfig(8) 1101 with the PHY specific default to typically off in order to protect 1102 from unwanted effects. Consequently, if you used flow control with 1103 one of the above mentioned drivers you now need to explicitly enable 1104 it, for example via: 1105 ifconfig bge0 media auto mediaopt flowcontrol 1106 1107 Along with the above mentioned changes generic support for setting 1108 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1109 e1000phy(4) as well as ip1000phy(4) have been converted to take 1110 advantage of it. This means that these drivers now no longer take the 1111 link0 parameter for selecting master mode but the master media option 1112 has to be used instead, for example like in the following: 1113 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1114 1115 Selection of master mode now is also available with all other PHY 1116 drivers supporting 1000baseT. 1117 111820101111: 1119 The TCP stack has received a significant update to add support for 1120 modularised congestion control and generally improve the clarity of 1121 congestion control decisions. Bump __FreeBSD_version to 900025. User 1122 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1123 sockstat) need to be recompiled. 1124 112520101002: 1126 The man(1) utility has been replaced by a new version that no longer 1127 uses /etc/manpath.config. Please consult man.conf(5) for how to 1128 migrate local entries to the new format. 1129 113020100928: 1131 The copyright strings printed by login(1) and sshd(8) at the time of a 1132 new connection have been removed to follow other operating systems and 1133 upstream sshd. 1134 113520100915: 1136 A workaround for a fixed ld bug has been removed in kernel code, 1137 so make sure that your system ld is built from sources after 1138 revision 210245 from 2010-07-19 (r211583 if building head kernel 1139 on stable/8, r211584 for stable/7; both from 2010-08-21). 1140 A symptom of incorrect ld version is different addresses for 1141 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1142 114320100913: 1144 The $ipv6_prefer variable in rc.conf(5) has been split into 1145 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1146 1147 The $ip6addrctl_policy is a variable to choose a pre-defined 1148 address selection policy set by ip6addrctl(8). A value 1149 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1150 default is "AUTO". 1151 1152 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1153 flag (see an entry of 20090926) is set on an interface with no 1154 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1155 security reason. If you want IPv6 link-local address on all 1156 interfaces by default, set this to "YES". 1157 1158 The old ipv6_prefer="YES" is equivalent to 1159 ipv6_activate_all_interfaces="YES" and 1160 ip6addrctl_policy="ipv6_prefer". 1161 116220100913: 1163 DTrace has grown support for userland tracing. Due to this, DTrace is 1164 now i386 and amd64 only. 1165 dtruss(1) is now installed by default on those systems and a new 1166 kernel module is needed for userland tracing: fasttrap. 1167 No changes to your kernel config file are necessary to enable 1168 userland tracing, but you might consider adding 'STRIP=' and 1169 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1170 to have informative userland stack traces in DTrace (ustack). 1171 117220100725: 1173 The acpi_aiboost(4) driver has been removed in favor of the new 1174 aibs(4) driver. You should update your kernel configuration file. 1175 117620100722: 1177 BSD grep has been imported to the base system and it is built by 1178 default. It is completely BSD licensed, highly GNU-compatible, uses 1179 less memory than its GNU counterpart and has a small codebase. 1180 However, it is slower than its GNU counterpart, which is mostly 1181 noticeable for larger searches, for smaller ones it is measurable 1182 but not significant. The reason is complex, the most important factor 1183 is that we lack a modern and efficient regex library and GNU 1184 overcomes this by optimizing the searches internally. Future work 1185 on improving the regex performance is planned, for the meantime, 1186 users that need better performance, can build GNU grep instead by 1187 setting the WITH_GNU_GREP knob. 1188 118920100713: 1190 Due to the import of powerpc64 support, all existing powerpc kernel 1191 configuration files must be updated with a machine directive like this: 1192 machine powerpc powerpc 1193 1194 In addition, an updated config(8) is required to build powerpc kernels 1195 after this change. 1196 119720100713: 1198 A new version of ZFS (version 15) has been merged to -HEAD. 1199 This version uses a python library for the following subcommands: 1200 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1201 For full functionality of these commands the following port must 1202 be installed: sysutils/py-zfs 1203 120420100429: 1205 'vm_page's are now hashed by physical address to an array of mutexes. 1206 Currently this is only used to serialize access to hold_count. Over 1207 time the page queue mutex will be peeled away. This changes the size 1208 of pmap on every architecture. And requires all callers of vm_page_hold 1209 and vm_page_unhold to be updated. 1210 121120100402: 1212 WITH_CTF can now be specified in src.conf (not recommended, there 1213 are some problems with static executables), make.conf (would also 1214 affect ports which do not use GNU make and do not override the 1215 compile targets) or in the kernel config (via "makeoptions 1216 WITH_CTF=yes"). 1217 When WITH_CTF was specified there before this was silently ignored, 1218 so make sure that WITH_CTF is not used in places which could lead 1219 to unwanted behavior. 1220 122120100311: 1222 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1223 to allow 32-bit compatibility on non-x86 platforms. All kernel 1224 configurations on amd64 and ia64 platforms using these options must 1225 be modified accordingly. 1226 122720100113: 1228 The utmp user accounting database has been replaced with utmpx, 1229 the user accounting interface standardized by POSIX. 1230 Unfortunately the semantics of utmp and utmpx don't match, 1231 making it practically impossible to support both interfaces. 1232 The user accounting database is used by tools like finger(1), 1233 last(1), talk(1), w(1) and ac(8). 1234 1235 All applications in the base system use utmpx. This means only 1236 local binaries (e.g. from the ports tree) may still use these 1237 utmp database files. These applications must be rebuilt to make 1238 use of utmpx. 1239 1240 After the system has been upgraded, it is safe to remove the old 1241 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1242 assuming their contents is of no importance anymore. Old wtmp 1243 databases can only be used by last(1) and ac(8) after they have 1244 been converted to the new format using wtmpcvt(1). 1245 124620100108: 1247 Introduce the kernel thread "deadlock resolver" (which can be enabled 1248 via the DEADLKRES option, see NOTES for more details) and the 1249 sleepq_type() function for sleepqueues. 1250 125120091202: 1252 The rc.firewall and rc.firewall6 were unified, and 1253 rc.firewall6 and rc.d/ip6fw were removed. 1254 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1255 variables are obsoleted. Instead, the following new rc 1256 variables are added to rc.d/ipfw: 1257 1258 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1259 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1260 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1261 1262 The meanings correspond to the relevant IPv4 variables. 1263 126420091125: 1265 8.0-RELEASE. 1266 126720091113: 1268 The default terminal emulation for syscons(4) has been changed 1269 from cons25 to xterm on all platforms except pc98. This means 1270 that the /etc/ttys file needs to be updated to ensure correct 1271 operation of applications on the console. 1272 1273 The terminal emulation style can be toggled per window by using 1274 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1275 options can be used to change the compile-time default back to 1276 cons25. 1277 1278 To prevent graphical artifacts, make sure the TERM environment 1279 variable is set to match the terminal emulation that is being 1280 performed by syscons(4). 1281 128220091109: 1283 The layout of the structure ieee80211req_scan_result has changed. 1284 Applications that require wireless scan results (e.g. ifconfig(8)) 1285 from net80211 need to be recompiled. 1286 1287 Applications such as wpa_supplicant(8) may require a full world 1288 build without using NO_CLEAN in order to get synchronized with the 1289 new structure. 1290 129120091025: 1292 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1293 There's one kernel module for each firmware. Adding "device iwnfw" 1294 to the kernel configuration file means including all three firmware 1295 images inside the kernel. If you want to include just the one for 1296 your wireless card, use the devices iwn4965fw, iwn5000fw or 1297 iwn5150fw. 1298 129920090926: 1300 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1301 into rc.d/netif. The changes are the following: 1302 1303 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1304 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1305 Note that both variables need the "inet6" keyword at the head. 1306 1307 Do not set $ipv6_network_interfaces manually if you do not 1308 understand what you are doing. It is not needed in most cases. 1309 1310 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1311 they are obsolete. 1312 1313 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1314 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1315 1316 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1317 all configured interfaces have "inet6 accept_rtadv" in the 1318 $ifconfig_IF_ipv6. These are for backward compatibility. 1319 1320 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1321 functionality of interfaces with no corresponding 1322 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1323 and the default address selection policy of ip6addrctl(8) 1324 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1325 Note that if you want to configure IPv6 functionality on the 1326 disabled interfaces after boot, first you need to clear the flag by 1327 using ifconfig(8) like: 1328 1329 ifconfig em0 inet6 -ifdisabled 1330 1331 If YES, the default address selection policy is set as 1332 IPv6-preferred. 1333 1334 The default value of $ipv6_prefer is NO. 1335 1336 4. If your system need to receive Router Advertisement messages, 1337 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1338 scripts automatically invoke rtsol(8) when the interface becomes 1339 UP. The Router Advertisement messages are used for SLAAC 1340 (State-Less Address AutoConfiguration). 1341 134220090922: 1343 802.11s D3.03 support was committed. This is incompatible with the 1344 previous code, which was based on D3.0. 1345 134620090912: 1347 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1348 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1349 control whether accepting Router Advertisement messages or not. 1350 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1351 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1352 The ifconfig(8) utility now supports these flags. 1353 135420090910: 1355 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1356 mount(8) and -a option for df(1) to see them. 1357 135820090825: 1359 The old tunable hw.bus.devctl_disable has been superseded by 1360 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1361 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1362 is 1000. 1363 136420090813: 1365 Remove the option STOP_NMI. The default action is now to use NMI only 1366 for KDB via the newly introduced function stop_cpus_hard() and 1367 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1368 136920090803: 1370 The stable/8 branch created in subversion. This corresponds to the 1371 RELENG_8 branch in CVS. 1372 137320090719: 1374 Bump the shared library version numbers for all libraries that do not 1375 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1376 __FreeBSD_version to 800105. 1377 137820090714: 1379 Due to changes in the implementation of virtual network stack support, 1380 all network-related kernel modules must be recompiled. As this change 1381 breaks the ABI, bump __FreeBSD_version to 800104. 1382 138320090713: 1384 The TOE interface to the TCP syncache has been modified to remove 1385 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1386 The cxgb driver is the only TOE consumer affected by this change, and 1387 needs to be recompiled along with the kernel. As this change breaks 1388 the ABI, bump __FreeBSD_version to 800103. 1389 139020090712: 1391 Padding has been added to struct tcpcb, sackhint and tcpstat in 1392 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1393 maintaining the ABI. However, this change breaks the ABI, so bump 1394 __FreeBSD_version to 800102. User space tools that rely on the size of 1395 any of these structs (e.g. sockstat) need to be recompiled. 1396 139720090630: 1398 The NFS_LEGACYRPC option has been removed along with the old kernel 1399 RPC implementation that this option selected. Kernel configurations 1400 may need to be adjusted. 1401 140220090629: 1403 The network interface device nodes at /dev/net/<interface> have been 1404 removed. All ioctl operations can be performed the normal way using 1405 routing sockets. The kqueue functionality can generally be replaced 1406 with routing sockets. 1407 140820090628: 1409 The documentation from the FreeBSD Documentation Project (Handbook, 1410 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1411 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1412 141320090624: 1414 The ABI of various structures related to the SYSV IPC API have been 1415 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1416 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1417 800100. 1418 141920090622: 1420 Layout of struct vnet has changed as routing related variables were 1421 moved to their own Vimage module. Modules need to be recompiled. Bump 1422 __FreeBSD_version to 800099. 1423 142420090619: 1425 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1426 respectively. As long as no more than 16 groups per process are used, 1427 no changes should be visible. When more than 16 groups are used, old 1428 binaries may fail if they call getgroups() or getgrouplist() with 1429 statically sized storage. Recompiling will work around this, but 1430 applications should be modified to use dynamically allocated storage 1431 for group arrays as POSIX.1-2008 does not cap an implementation's 1432 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1433 1434 NFS and portalfs mounts may also be affected as the list of groups is 1435 truncated to 16. Users of NFS who use more than 16 groups, should 1436 take care that negative group permissions are not used on the exported 1437 file systems as they will not be reliable unless a GSSAPI based 1438 authentication method is used. 1439 144020090616: 1441 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1442 option compiles in the support for adaptive spinning for lockmgrs 1443 which want to enable it. The lockinit() function now accepts the flag 1444 LK_ADAPTIVE in order to make the lock object subject to adaptive 1445 spinning when both held in write and read mode. 1446 144720090613: 1448 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1449 changed. User applications that use this ioctl need to be rebuilt. 1450 145120090611: 1452 The layout of struct thread has changed. Kernel and modules need to 1453 be rebuilt. 1454 145520090608: 1456 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1457 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1458 145920090602: 1460 window(1) has been removed from the base system. It can now be 1461 installed from ports. The port is called misc/window. 1462 146320090601: 1464 The way we are storing and accessing `routing table' entries has 1465 changed. Programs reading the FIB, like netstat, need to be 1466 re-compiled. 1467 146820090601: 1469 A new netisr implementation has been added for FreeBSD 8. Network 1470 file system modules, such as igmp, ipdivert, and others, should be 1471 rebuilt. 1472 Bump __FreeBSD_version to 800096. 1473 147420090530: 1475 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1476 more valid. 1477 147820090530: 1479 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1480 Bump __FreeBSD_version to 800094. 1481 148220090529: 1483 Add mnt_xflag field to 'struct mount'. File system modules need to be 1484 rebuilt. 1485 Bump __FreeBSD_version to 800093. 1486 148720090528: 1488 The compiling option ADAPTIVE_SX has been retired while it has been 1489 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1490 The KPI for sx_init_flags() changes as accepting flags: 1491 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1492 been introduced in order to handle the reversed logic. 1493 Bump __FreeBSD_version to 800092. 1494 149520090527: 1496 Add support for hierarchical jails. Remove global securelevel. 1497 Bump __FreeBSD_version to 800091. 1498 149920090523: 1500 The layout of struct vnet_net has changed, therefore modules 1501 need to be rebuilt. 1502 Bump __FreeBSD_version to 800090. 1503 150420090523: 1505 The newly imported zic(8) produces a new format in the output. Please 1506 run tzsetup(8) to install the newly created data to /etc/localtime. 1507 150820090520: 1509 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1510 hw.usb.* and is now consistent again with previous releases. 1511 151220090520: 1513 802.11 monitor mode support was revised and driver api's were changed. 1514 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1515 of DLT_IEEE802_11. No user-visible data structures were changed but 1516 applications that use DLT_IEEE802_11 may require changes. 1517 Bump __FreeBSD_version to 800088. 1518 151920090430: 1520 The layout of the following structs has changed: sysctl_oid, 1521 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1522 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1523 panics may be experienced. World rebuild is required for 1524 correctly checking networking state from userland. 1525 Bump __FreeBSD_version to 800085. 1526 152720090429: 1528 MLDv2 and Source-Specific Multicast (SSM) have been merged 1529 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1530 The implementation of SSM within FreeBSD's IPv6 stack closely 1531 follows the IPv4 implementation. 1532 1533 For kernel developers: 1534 1535 * The most important changes are that the ip6_output() and 1536 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1537 and this lock has been downgraded to a non-recursive mutex. 1538 1539 * As with the changes to the IPv4 stack to support SSM, filtering 1540 of inbound multicast traffic must now be performed by transport 1541 protocols within the IPv6 stack. This does not apply to TCP and 1542 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1543 1544 * The KPIs used by IPv6 multicast are similar to those used by 1545 the IPv4 stack, with the following differences: 1546 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1547 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1548 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1549 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1550 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1551 for MLDv1 have an additional 'timer' argument which is used to 1552 jitter the initial membership report for the solicited-node 1553 multicast membership on-link. 1554 * This is not strictly needed for MLDv2, which already jitters 1555 its report transmissions. However, the 'timer' argument is 1556 preserved in case MLDv1 is active on the interface. 1557 1558 * The KAME linked-list based IPv6 membership implementation has 1559 been refactored to use a vector similar to that used by the IPv4 1560 stack. 1561 Code which maintains a list of its own multicast memberships 1562 internally, e.g. carp, has been updated to reflect the new 1563 semantics. 1564 1565 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1566 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1567 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1568 implementation constraint which needs to be addressed in HEAD. 1569 1570 For application developers: 1571 1572 * The changes are broadly similar to those made for the IPv4 1573 stack. 1574 1575 * The use of IPv4 and IPv6 multicast socket options on the same 1576 socket, using mapped addresses, HAS NOT been tested or supported. 1577 1578 * There are a number of issues with the implementation of various 1579 IPv6 multicast APIs which need to be resolved in the API surface 1580 before the implementation is fully compatible with KAME userland 1581 use, and these are mostly to do with interface index treatment. 1582 1583 * The literature available discusses the use of either the delta / ASM 1584 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1585 using setsourcefilter(3)/getsourcefilter(3). For more information 1586 please refer to RFC 3768, 'Socket Interface Extensions for 1587 Multicast Source Filters'. 1588 1589 * Applications which use the published RFC 3678 APIs should be fine. 1590 1591 For systems administrators: 1592 1593 * The mtest(8) utility has been refactored to support IPv6, in 1594 addition to IPv4. Interface addresses are no longer accepted 1595 as arguments, their names must be used instead. The utility 1596 will map the interface name to its first IPv4 address as 1597 returned by getifaddrs(3). 1598 1599 * The ifmcstat(8) utility has also been updated to print the MLDv2 1600 endpoint state and source filter lists via sysctl(3). 1601 1602 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1603 loopback of IPv6 multicast datagrams by default; it defaults to 1 1604 to preserve the existing behaviour. Disabling multicast loopback is 1605 recommended for optimal system performance. 1606 1607 * The IPv6 MROUTING code has been changed to examine this sysctl 1608 instead of attempting to perform a group lookup before looping 1609 back forwarded datagrams. 1610 1611 Bump __FreeBSD_version to 800084. 1612 161320090422: 1614 Implement low-level Bluetooth HCI API. 1615 Bump __FreeBSD_version to 800083. 1616 161720090419: 1618 The layout of struct malloc_type, used by modules to register new 1619 memory allocation types, has changed. Most modules will need to 1620 be rebuilt or panics may be experienced. 1621 Bump __FreeBSD_version to 800081. 1622 162320090415: 1624 Anticipate overflowing inp_flags - add inp_flags2. 1625 This changes most offsets in inpcb, so checking v4 connection 1626 state will require a world rebuild. 1627 Bump __FreeBSD_version to 800080. 1628 162920090415: 1630 Add an llentry to struct route and struct route_in6. Modules 1631 embedding a struct route will need to be recompiled. 1632 Bump __FreeBSD_version to 800079. 1633 163420090414: 1635 The size of rt_metrics_lite and by extension rtentry has changed. 1636 Networking administration apps will need to be recompiled. 1637 The route command now supports show as an alias for get, weighting 1638 of routes, sticky and nostick flags to alter the behavior of stateful 1639 load balancing. 1640 Bump __FreeBSD_version to 800078. 1641 164220090408: 1643 Do not use Giant for kbdmux(4) locking. This is wrong and 1644 apparently causing more problems than it solves. This will 1645 re-open the issue where interrupt handlers may race with 1646 kbdmux(4) in polling mode. Typical symptoms include (but 1647 not limited to) duplicated and/or missing characters when 1648 low level console functions (such as gets) are used while 1649 interrupts are enabled (for example geli password prompt, 1650 mountroot prompt etc.). Disabling kbdmux(4) may help. 1651 165220090407: 1653 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1654 kernel modules referencing any of the above need to be recompiled. 1655 Bump __FreeBSD_version to 800075. 1656 165720090320: 1658 GEOM_PART has become the default partition slicer for storage devices, 1659 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1660 introduces some changes: 1661 1662 MSDOS/EBR: the devices created from MSDOS extended partition entries 1663 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1664 to devices with offset-based names. fstabs may need to be modified. 1665 1666 BSD: the "geometry does not match label" warning is harmless in most 1667 cases but it points to problems in file system misalignment with 1668 disk geometry. The "c" partition is now implicit, covers the whole 1669 top-level drive and cannot be (mis)used by users. 1670 1671 General: Kernel dumps are now not allowed to be written to devices 1672 whose partition types indicate they are meant to be used for file 1673 systems (or, in case of MSDOS partitions, as something else than 1674 the "386BSD" type). 1675 1676 Most of these changes date approximately from 200812. 1677 167820090319: 1679 The uscanner(4) driver has been removed from the kernel. This follows 1680 Linux removing theirs in 2.6 and making libusb the default interface 1681 (supported by sane). 1682 168320090319: 1684 The multicast forwarding code has been cleaned up. netstat(1) 1685 only relies on KVM now for printing bandwidth upcall meters. 1686 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1687 ip6_mroute_mod respectively. The config(5) options for statically 1688 compiling this code remain the same, i.e. 'options MROUTING'. 1689 169020090315: 1691 Support for the IFF_NEEDSGIANT network interface flag has been 1692 removed, which means that non-MPSAFE network device drivers are no 1693 longer supported. In particular, if_ar, if_sr, and network device 1694 drivers from the old (legacy) USB stack can no longer be built or 1695 used. 1696 169720090313: 1698 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1699 a bunch of new language catalog files have also been added. 1700 This means that some common libc messages are now localized and 1701 they depend on the LC_MESSAGES environmental variable. 1702 170320090313: 1704 The k8temp(4) driver has been renamed to amdtemp(4) since 1705 support for Family 10 and Family 11 CPU families was added. 1706 170720090309: 1708 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1709 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1710 1711 For kernel developers, the most important changes are that the 1712 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1713 and this lock has been downgraded to a non-recursive mutex. 1714 1715 Transport protocols (UDP, Raw IP) are now responsible for filtering 1716 inbound multicast traffic according to group membership and source 1717 filters. The imo_multicast_filter() KPI exists for this purpose. 1718 Transports which do not use multicast (SCTP, TCP) already reject 1719 multicast by default. Forwarding and receive performance may improve 1720 as a mutex acquisition is no longer needed in the ip_input() 1721 low-level input path. in_addmulti() and in_delmulti() are shimmed 1722 to new KPIs which exist to support SSM in-kernel. 1723 1724 For application developers, it is recommended that loopback of 1725 multicast datagrams be disabled for best performance, as this 1726 will still cause the lock to be taken for each looped-back 1727 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1728 be tuned to 0 to disable loopback by default; it defaults to 1 1729 to preserve the existing behaviour. 1730 1731 For systems administrators, to obtain best performance with 1732 multicast reception and multiple groups, it is always recommended 1733 that a card with a suitably precise hash filter is used. Hash 1734 collisions will still result in the lock being taken within the 1735 transport protocol input path to check group membership. 1736 1737 If deploying FreeBSD in an environment with IGMP snooping switches, 1738 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1739 enabled; this forces 224.0.0.0/24 group membership to be announced 1740 via IGMP. 1741 1742 The size of 'struct igmpstat' has changed; netstat needs to be 1743 recompiled to reflect this. 1744 Bump __FreeBSD_version to 800070. 1745 174620090309: 1747 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1748 updated to use it. This requires a buildworld/installworld in order to 1749 update the library and dependencies (usbconfig, etc). Its advisable to 1750 rebuild all ports which uses libusb. More specific directions are given 1751 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1752 libusb are no longer required and can be removed. 1753 175420090302: 1755 A workaround is committed to allow the creation of System V shared 1756 memory segment of size > 2 GB on the 64-bit architectures. 1757 Due to a limitation of the existing ABI, the shm_segsz member 1758 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1759 wrong for large segments. Note that limits must be explicitly 1760 raised to allow such segments to be created. 1761 176220090301: 1763 The layout of struct ifnet has changed, requiring a rebuild of all 1764 network device driver modules. 1765 176620090227: 1767 The /dev handling for the new USB stack has changed, a 1768 buildworld/installworld is required for libusb20. 1769 177020090223: 1771 The new USB2 stack has now been permanently moved in and all kernel and 1772 module names reverted to their previous values (eg, usb, ehci, ohci, 1773 ums, ...). The old usb stack can be compiled in by prefixing the name 1774 with the letter 'o', the old usb modules have been removed. 1775 Updating entry 20090216 for xorg and 20090215 for libmap may still 1776 apply. 1777 177820090217: 1779 The rc.conf(5) option if_up_delay has been renamed to 1780 defaultroute_delay to better reflect its purpose. If you have 1781 customized this setting in /etc/rc.conf you need to update it to 1782 use the new name. 1783 178420090216: 1785 xorg 7.4 wants to configure its input devices via hald which does not 1786 yet work with USB2. If the keyboard/mouse does not work in xorg then 1787 add 1788 Option "AllowEmptyInput" "off" 1789 to your ServerLayout section. This will cause X to use the configured 1790 kbd and mouse sections from your xorg.conf. 1791 179220090215: 1793 The GENERIC kernels for all architectures now default to the new USB2 1794 stack. No kernel config options or code have been removed so if a 1795 problem arises please report it and optionally revert to the old USB 1796 stack. If you are loading USB kernel modules or have a custom kernel 1797 that includes GENERIC then ensure that usb names are also changed over, 1798 eg uftdi -> usb2_serial_ftdi. 1799 1800 Older programs linked against the ports libusb 0.1 need to be 1801 redirected to the new stack's libusb20. /etc/libmap.conf can 1802 be used for this: 1803 # Map old usb library to new one for usb2 stack 1804 libusb-0.1.so.8 libusb20.so.1 1805 180620090209: 1807 All USB ethernet devices now attach as interfaces under the name ueN 1808 (eg. ue0). This is to provide a predictable name as vendors often 1809 change usb chipsets in a product without notice. 1810 181120090203: 1812 The ichsmb(4) driver has been changed to require SMBus slave 1813 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1814 All of the other SMBus controller drivers require left-justified 1815 slave addresses, so this change makes all the drivers provide the 1816 same interface. 1817 181820090201: 1819 INET6 statistics (struct ip6stat) was updated. 1820 netstat(1) needs to be recompiled. 1821 182220090119: 1823 NTFS has been removed from GENERIC kernel on amd64 to match 1824 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1825 will load ntfs.ko module automatically when NTFS support is 1826 actually needed, unless ntfs.ko is not installed or security 1827 level prohibits loading kernel modules. If either is the case, 1828 "options NTFS" has to be added into kernel config. 1829 183020090115: 1831 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1832 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1833 800061. User space tools that rely on the size of struct tcpcb in 1834 tcp_var.h (e.g. sockstat) need to be recompiled. 1835 183620081225: 1837 ng_tty(4) module updated to match the new TTY subsystem. 1838 Due to API change, user-level applications must be updated. 1839 New API support added to mpd5 CVS and expected to be present 1840 in next mpd5.3 release. 1841 184220081219: 1843 With __FreeBSD_version 800060 the makefs tool is part of 1844 the base system (it was a port). 1845 184620081216: 1847 The afdata and ifnet locks have been changed from mutexes to 1848 rwlocks, network modules will need to be re-compiled. 1849 185020081214: 1851 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1852 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1853 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1854 architecture and 40 bytes on 64-bit architecture. The userland 1855 applications "arp" and "ndp" have been updated accordingly. 1856 The output from "netstat -r" shows only routing entries and 1857 none of the L2 information. 1858 185920081130: 1860 __FreeBSD_version 800057 marks the switchover from the 1861 binary ath hal to source code. Users must add the line: 1862 1863 options AH_SUPPORT_AR5416 1864 1865 to their kernel config files when specifying: 1866 1867 device ath_hal 1868 1869 The ath_hal module no longer exists; the code is now compiled 1870 together with the driver in the ath module. It is now 1871 possible to tailor chip support (i.e. reduce the set of chips 1872 and thereby the code size); consult ath_hal(4) for details. 1873 187420081121: 1875 __FreeBSD_version 800054 adds memory barriers to 1876 <machine/atomic.h>, new interfaces to ifnet to facilitate 1877 multiple hardware transmit queues for cards that support 1878 them, and a lock-less ring-buffer implementation to 1879 enable drivers to more efficiently manage queueing of 1880 packets. 1881 188220081117: 1883 A new version of ZFS (version 13) has been merged to -HEAD. 1884 This version has zpool attribute "listsnapshots" off by 1885 default, which means "zfs list" does not show snapshots, 1886 and is the same as Solaris behavior. 1887 188820081028: 1889 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1890 189120081009: 1892 The uhci, ohci, ehci and slhci USB Host controller drivers have 1893 been put into separate modules. If you load the usb module 1894 separately through loader.conf you will need to load the 1895 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1896 controller add the following to loader.conf: 1897 1898 uhci_load="YES" 1899 ehci_load="YES" 1900 190120081009: 1902 The ABI used by the PMC toolset has changed. Please keep 1903 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1904 sync. 1905 190620081009: 1907 atapci kernel module now includes only generic PCI ATA 1908 driver. AHCI driver moved to ataahci kernel module. 1909 All vendor-specific code moved into separate kernel modules: 1910 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1911 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1912 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1913 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1914 191520080820: 1916 The TTY subsystem of the kernel has been replaced by a new 1917 implementation, which provides better scalability and an 1918 improved driver model. Most common drivers have been migrated to 1919 the new TTY subsystem, while others have not. The following 1920 drivers have not yet been ported to the new TTY layer: 1921 1922 PCI/ISA: 1923 cy, digi, rc, rp, sio 1924 1925 USB: 1926 ubser, ucycom 1927 1928 Line disciplines: 1929 ng_h4, ng_tty, ppp, sl, snp 1930 1931 Adding these drivers to your kernel configuration file shall 1932 cause compilation to fail. 1933 193420080818: 1935 ntpd has been upgraded to 4.2.4p5. 1936 193720080801: 1938 OpenSSH has been upgraded to 5.1p1. 1939 1940 For many years, FreeBSD's version of OpenSSH preferred DSA 1941 over RSA for host and user authentication keys. With this 1942 upgrade, we've switched to the vendor's default of RSA over 1943 DSA. This may cause upgraded clients to warn about unknown 1944 host keys even for previously known hosts. Users should 1945 follow the usual procedure for verifying host keys before 1946 accepting the RSA key. 1947 1948 This can be circumvented by setting the "HostKeyAlgorithms" 1949 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1950 command line. 1951 1952 Please note that the sequence of keys offered for 1953 authentication has been changed as well. You may want to 1954 specify IdentityFile in a different order to revert this 1955 behavior. 1956 195720080713: 1958 The sio(4) driver has been removed from the i386 and amd64 1959 kernel configuration files. This means uart(4) is now the 1960 default serial port driver on those platforms as well. 1961 1962 To prevent collisions with the sio(4) driver, the uart(4) driver 1963 uses different names for its device nodes. This means the 1964 onboard serial port will now most likely be called "ttyu0" 1965 instead of "ttyd0". You may need to reconfigure applications to 1966 use the new device names. 1967 1968 When using the serial port as a boot console, be sure to update 1969 /boot/device.hints and /etc/ttys before booting the new kernel. 1970 If you forget to do so, you can still manually specify the hints 1971 at the loader prompt: 1972 1973 set hint.uart.0.at="isa" 1974 set hint.uart.0.port="0x3F8" 1975 set hint.uart.0.flags="0x10" 1976 set hint.uart.0.irq="4" 1977 boot -s 1978 197920080609: 1980 The gpt(8) utility has been removed. Use gpart(8) to partition 1981 disks instead. 1982 198320080603: 1984 The version that Linuxulator emulates was changed from 2.4.2 1985 to 2.6.16. If you experience any problems with Linux binaries 1986 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1987 if it fixes the problem contact emulation mailing list. 1988 198920080525: 1990 ISDN4BSD (I4B) was removed from the src tree. You may need to 1991 update a your kernel configuration and remove relevant entries. 1992 199320080509: 1994 I have checked in code to support multiple routing tables. 1995 See the man pages setfib(1) and setfib(2). 1996 This is a hopefully backwards compatible version, 1997 but to make use of it you need to compile your kernel 1998 with options ROUTETABLES=2 (or more up to 16). 1999 200020080420: 2001 The 802.11 wireless support was redone to enable multi-bss 2002 operation on devices that are capable. The underlying device 2003 is no longer used directly but instead wlanX devices are 2004 cloned with ifconfig. This requires changes to rc.conf files. 2005 For example, change: 2006 ifconfig_ath0="WPA DHCP" 2007 to 2008 wlans_ath0=wlan0 2009 ifconfig_wlan0="WPA DHCP" 2010 see rc.conf(5) for more details. In addition, mergemaster of 2011 /etc/rc.d is highly recommended. Simultaneous update of userland 2012 and kernel wouldn't hurt either. 2013 2014 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2015 modules were merged into the base wlan module. All references 2016 to these modules (e.g. in kernel config files) must be removed. 2017 201820080408: 2019 psm(4) has gained write(2) support in native operation level. 2020 Arbitrary commands can be written to /dev/psm%d and status can 2021 be read back from it. Therefore, an application is responsible 2022 for status validation and error recovery. It is a no-op in 2023 other operation levels. 2024 202520080312: 2026 Support for KSE threading has been removed from the kernel. To 2027 run legacy applications linked against KSE libmap.conf may 2028 be used. The following libmap.conf may be used to ensure 2029 compatibility with any prior release: 2030 2031 libpthread.so.1 libthr.so.1 2032 libpthread.so.2 libthr.so.2 2033 libkse.so.3 libthr.so.3 2034 203520080301: 2036 The layout of struct vmspace has changed. This affects libkvm 2037 and any executables that link against libkvm and use the 2038 kvm_getprocs() function. In particular, but not exclusively, 2039 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2040 The effects are minimal, but it's advisable to upgrade world 2041 nonetheless. 2042 204320080229: 2044 The latest em driver no longer has support in it for the 2045 82575 adapter, this is now moved to the igb driver. The 2046 split was done to make new features that are incompatible 2047 with older hardware easier to do. 2048 204920080220: 2050 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2051 likewise the kernel option is now GEOM_LINUX_LVM. 2052 205320080211: 2054 The default NFS mount mode has changed from UDP to TCP for 2055 increased reliability. If you rely on (insecurely) NFS 2056 mounting across a firewall you may need to update your 2057 firewall rules. 2058 205920080208: 2060 Belatedly note the addition of m_collapse for compacting 2061 mbuf chains. 2062 206320080126: 2064 The fts(3) structures have been changed to use adequate 2065 integer types for their members and so to be able to cope 2066 with huge file trees. The old fts(3) ABI is preserved 2067 through symbol versioning in libc, so third-party binaries 2068 using fts(3) should still work, although they will not take 2069 advantage of the extended types. At the same time, some 2070 third-party software might fail to build after this change 2071 due to unportable assumptions made in its source code about 2072 fts(3) structure members. Such software should be fixed 2073 by its vendor or, in the worst case, in the ports tree. 2074 FreeBSD_version 800015 marks this change for the unlikely 2075 case that a portable fix is impossible. 2076 207720080123: 2078 To upgrade to -current after this date, you must be running 2079 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2080 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2081 208220071128: 2083 The ADAPTIVE_GIANT kernel option has been retired because its 2084 functionality is the default now. 2085 208620071118: 2087 The AT keyboard emulation of sunkbd(4) has been turned on 2088 by default. In order to make the special symbols of the Sun 2089 keyboards driven by sunkbd(4) work under X these now have 2090 to be configured the same way as Sun USB keyboards driven 2091 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2092 2093 Option "XkbLayout" "us" 2094 Option "XkbRules" "xorg" 2095 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2096 209720071024: 2098 It has been decided that it is desirable to provide ABI 2099 backwards compatibility to the FreeBSD 4/5/6 versions of the 2100 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2101 broken with the introduction of PCI domain support (see the 2102 20070930 entry). Unfortunately, this required the ABI of 2103 PCIOCGETCONF to be broken again in order to be able to 2104 provide backwards compatibility to the old version of that 2105 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2106 again. As for prominent ports this affects neither pciutils 2107 nor xorg-server this time, the hal port needs to be rebuilt 2108 however. 2109 211020071020: 2111 The misnamed kthread_create() and friends have been renamed 2112 to kproc_create() etc. Many of the callers already 2113 used kproc_start().. 2114 I will return kthread_create() and friends in a while 2115 with implementations that actually create threads, not procs. 2116 Renaming corresponds with version 800002. 2117 211820071010: 2119 RELENG_7 branched. 2120 2121COMMON ITEMS: 2122 2123 General Notes 2124 ------------- 2125 Avoid using make -j when upgrading. While generally safe, there are 2126 sometimes problems using -j to upgrade. If your upgrade fails with 2127 -j, please try again without -j. From time to time in the past there 2128 have been problems using -j with buildworld and/or installworld. This 2129 is especially true when upgrading between "distant" versions (eg one 2130 that cross a major release boundary or several minor releases, or when 2131 several months have passed on the -current branch). 2132 2133 Sometimes, obscure build problems are the result of environment 2134 poisoning. This can happen because the make utility reads its 2135 environment when searching for values for global variables. To run 2136 your build attempts in an "environmental clean room", prefix all make 2137 commands with 'env -i '. See the env(1) manual page for more details. 2138 2139 When upgrading from one major version to another it is generally best 2140 to upgrade to the latest code in the currently installed branch first, 2141 then do an upgrade to the new branch. This is the best-tested upgrade 2142 path, and has the highest probability of being successful. Please try 2143 this approach before reporting problems with a major version upgrade. 2144 2145 When upgrading a live system, having a root shell around before 2146 installing anything can help undo problems. Not having a root shell 2147 around can lead to problems if pam has changed too much from your 2148 starting point to allow continued authentication after the upgrade. 2149 2150 ZFS notes 2151 --------- 2152 When upgrading the boot ZFS pool to a new version, always follow 2153 these two steps: 2154 2155 1.) recompile and reinstall the ZFS boot loader and boot block 2156 (this is part of "make buildworld" and "make installworld") 2157 2158 2.) update the ZFS boot block on your boot drive 2159 2160 The following example updates the ZFS boot block on the first 2161 partition (freebsd-boot) of a GPT partitioned drive ad0: 2162 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2163 2164 Non-boot pools do not need these updates. 2165 2166 To build a kernel 2167 ----------------- 2168 If you are updating from a prior version of FreeBSD (even one just 2169 a few days old), you should follow this procedure. It is the most 2170 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2171 2172 make kernel-toolchain 2173 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2174 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2175 2176 To test a kernel once 2177 --------------------- 2178 If you just want to boot a kernel once (because you are not sure 2179 if it works, or if you want to boot a known bad kernel to provide 2180 debugging information) run 2181 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2182 nextboot -k testkernel 2183 2184 To just build a kernel when you know that it won't mess you up 2185 -------------------------------------------------------------- 2186 This assumes you are already running a CURRENT system. Replace 2187 ${arch} with the architecture of your machine (e.g. "i386", 2188 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2189 2190 cd src/sys/${arch}/conf 2191 config KERNEL_NAME_HERE 2192 cd ../compile/KERNEL_NAME_HERE 2193 make depend 2194 make 2195 make install 2196 2197 If this fails, go to the "To build a kernel" section. 2198 2199 To rebuild everything and install it on the current system. 2200 ----------------------------------------------------------- 2201 # Note: sometimes if you are running current you gotta do more than 2202 # is listed here if you are upgrading from a really old current. 2203 2204 <make sure you have good level 0 dumps> 2205 make buildworld 2206 make kernel KERNCONF=YOUR_KERNEL_HERE 2207 [1] 2208 <reboot in single user> [3] 2209 mergemaster -p [5] 2210 make installworld 2211 mergemaster -i [4] 2212 make delete-old [6] 2213 <reboot> 2214 2215 To cross-install current onto a separate partition 2216 -------------------------------------------------- 2217 # In this approach we use a separate partition to hold 2218 # current's root, 'usr', and 'var' directories. A partition 2219 # holding "/", "/usr" and "/var" should be about 2GB in 2220 # size. 2221 2222 <make sure you have good level 0 dumps> 2223 <boot into -stable> 2224 make buildworld 2225 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2226 <maybe newfs current's root partition> 2227 <mount current's root partition on directory ${CURRENT_ROOT}> 2228 make installworld DESTDIR=${CURRENT_ROOT} 2229 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2230 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2231 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2232 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2233 <reboot into current> 2234 <do a "native" rebuild/install as described in the previous section> 2235 <maybe install compatibility libraries from ports/misc/compat*> 2236 <reboot> 2237 2238 2239 To upgrade in-place from stable to current 2240 ---------------------------------------------- 2241 <make sure you have good level 0 dumps> 2242 make buildworld [9] 2243 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2244 [1] 2245 <reboot in single user> [3] 2246 mergemaster -p [5] 2247 make installworld 2248 mergemaster -i [4] 2249 make delete-old [6] 2250 <reboot> 2251 2252 Make sure that you've read the UPDATING file to understand the 2253 tweaks to various things you need. At this point in the life 2254 cycle of current, things change often and you are on your own 2255 to cope. The defaults can also change, so please read ALL of 2256 the UPDATING entries. 2257 2258 Also, if you are tracking -current, you must be subscribed to 2259 freebsd-current@freebsd.org. Make sure that before you update 2260 your sources that you have read and understood all the recent 2261 messages there. If in doubt, please track -stable which has 2262 much fewer pitfalls. 2263 2264 [1] If you have third party modules, such as vmware, you 2265 should disable them at this point so they don't crash your 2266 system on reboot. 2267 2268 [3] From the bootblocks, boot -s, and then do 2269 fsck -p 2270 mount -u / 2271 mount -a 2272 cd src 2273 adjkerntz -i # if CMOS is wall time 2274 Also, when doing a major release upgrade, it is required that 2275 you boot into single user mode to do the installworld. 2276 2277 [4] Note: This step is non-optional. Failure to do this step 2278 can result in a significant reduction in the functionality of the 2279 system. Attempting to do it by hand is not recommended and those 2280 that pursue this avenue should read this file carefully, as well 2281 as the archives of freebsd-current and freebsd-hackers mailing lists 2282 for potential gotchas. The -U option is also useful to consider. 2283 See mergemaster(8) for more information. 2284 2285 [5] Usually this step is a noop. However, from time to time 2286 you may need to do this if you get unknown user in the following 2287 step. It never hurts to do it all the time. You may need to 2288 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2289 install) after the buildworld before this step if you last updated 2290 from current before 20130425 or from -stable before 20130430. 2291 2292 [6] This only deletes old files and directories. Old libraries 2293 can be deleted by "make delete-old-libs", but you have to make 2294 sure that no program is using those libraries anymore. 2295 2296 [8] In order to have a kernel that can run the 4.x binaries needed to 2297 do an installworld, you must include the COMPAT_FREEBSD4 option in 2298 your kernel. Failure to do so may leave you with a system that is 2299 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2300 required to run the 5.x binaries on more recent kernels. And so on 2301 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2302 2303 Make sure that you merge any new devices from GENERIC since the 2304 last time you updated your kernel config file. 2305 2306 [9] When checking out sources, you must include the -P flag to have 2307 cvs prune empty directories. 2308 2309 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2310 "?=" instead of the "=" assignment operator, so that buildworld can 2311 override the CPUTYPE if it needs to. 2312 2313 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2314 not on the command line, or in /etc/make.conf. buildworld will 2315 warn if it is improperly defined. 2316FORMAT: 2317 2318This file contains a list, in reverse chronological order, of major 2319breakages in tracking -current. It is not guaranteed to be a complete 2320list of such breakages, and only contains entries since October 10, 2007. 2321If you need to see UPDATING entries from before that date, you will need 2322to fetch an UPDATING file from an older FreeBSD release. 2323 2324Copyright information: 2325 2326Copyright 1998-2009 M.
