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 1920180404 p29 FreeBSD-SA-18:04.vt 20 FreeBSD-SA-18:05.ipsec 21 FreeBSD-EN-18:03.tzdata 22 FreeBSD-EN-18:04.mem 23 24 Fix vt console memory disclosure.

They are 222 still available in the security/openssh-portable port. 223 22420151214: 225 r292223 changed the internal interface between the nfsd.ko and 226 nfscommon.ko modules. As such, they must both be upgraded to-gether. 227 __FreeBSD_version has been bumped because of this. 228 22920151113: 230 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 231 Kernel modules isp_2400_multi and isp_2500_multi were removed and 232 should be replaced with isp_2400 and isp_2500 modules respectively. 233 23420150806: 235 The menu.rc and loader.rc files will now be replaced during 236 upgrades. Please migrate local changes to menu.rc.local and 237 loader.rc.local instead. 238 23920151026: 240 NTP has been upgraded to 4.2.8p4. 241 24220151025: 243 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 244 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 245 and devel/kyua to version 0.20+ and adjust any calling code to work 246 with Kyuafile and kyua. 247 24820150823: 249 The polarity of Pulse Per Second (PPS) capture events with the 250 uart(4) driver has been corrected. Prior to this change the PPS 251 "assert" event corresponded to the trailing edge of a positive PPS 252 pulse and the "clear" event was the leading edge of the next pulse. 253 254 As the width of a PPS pulse in a typical GPS receiver is on the 255 order of 1 millisecond, most users will not notice any significant 256 difference with this change. 257 258 Anyone who has compensated for the historical polarity reversal by 259 configuring a negative offset equal to the pulse width will need to 260 remove that workaround. 261 26220150822: 263 From legacy ata(4) driver was removed support for SATA controllers 264 supported by more functional drivers ahci(4), siis(4) and mvs(4). 265 Kernel modules ataahci and ataadaptec were removed completely, 266 replaced by ahci and mvs modules respectively. 267 26820150813: 269 10.2-RELEASE. 270 27120150731: 272 As ZFS requires more kernel stack pages than is the default on some 273 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 274 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 275 276 Please consider using 'options KSTACK_PAGES=X' where X is greater 277 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 278 27920150703: 280 The default Unbound configuration now enables remote control 281 using a local socket. Users who have already enabled the 282 local_unbound service should regenerate their configuration 283 by running "service local_unbound setup" as root. 284 28520150624: 286 An additional fix for the issue described in the 20150614 sendmail 287 entry below has been been committed in revision 284786. 288 28920150615: 290 The fix for the issue described in the 20150614 sendmail entry 291 below has been been committed in revision 284485. The work 292 around described in that entry is no longer needed unless the 293 default setting is overridden by a confDH_PARAMETERS configuration 294 setting of '5' or pointing to a 512 bit DH parameter file. 295 29620150614: 297 The import of openssl to address the FreeBSD-SA-15:10.openssl 298 security advisory includes a change which rejects handshakes 299 with DH parameters below 768 bits. sendmail releases prior 300 to 8.15.2 (not yet released), defaulted to a 512 bit 301 DH parameter setting for client connections. To work around 302 this interoperability, sendmail can be configured to use a 303 2048 bit DH parameter by: 304 305 1. Edit /etc/mail/`hostname`.mc 306 2. If a setting for confDH_PARAMETERS does not exist or 307 exists and is set to a string beginning with '5', 308 replace it with '2'. 309 3. If a setting for confDH_PARAMETERS exists and is set to 310 a file path, create a new file with: 311 openssl dhparam -out /path/to/file 2048 312 4. Rebuild the .cf file: 313 cd /etc/mail/; make; make install 314 5. Restart sendmail: 315 cd /etc/mail/; make restart 316 317 A sendmail patch is coming, at which time this file will be 318 updated. 319 32020150601: 321 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 322 defined in symlink(7); previously symlinks were silently ignored. 323 32420150430: 325 The const qualifier has been removed from iconv(3) to comply with 326 POSIX. The ports tree is aware of this from r384038 onwards. 327 32820141215: 329 At svn r275807, The default linux compat kernel ABI has been adjusted 330 to 2.6.18 in support of the linux-c6 compat ports infrastructure 331 update. If you wish to continue using the linux-f10 compat ports, 332 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 333 encouraged to update their linux-compat packages to linux-c6 during 334 their next update cycle. 335 336 See ports/UPDATING 20141209 and 20141215 on migration to CentOS 6 ports. 337 33820141205: 339 pjdfstest has been integrated into kyua as an opt-in test suite. 340 Please see share/doc/pjdfstest/README for a more details on how to 341 execute it. 342 34320141118: 344 10.1-RELEASE. 345 34620140904: 347 The ofwfb driver, used to provide a graphics console on PowerPC when 348 using vt(4), no longer allows mmap() of all of physical memory. This 349 will prevent Xorg on PowerPC with some ATI graphics cards from 350 initializing properly unless x11-servers/xorg-server is updated to 351 1.12.4_8 or newer. 352 35320140831: 354 The libatf-c and libatf-c++ major versions were downgraded to 0 and 355 1 respectively to match the upstream numbers. They were out of 356 sync because, when they were originally added to FreeBSD, the 357 upstream versions were not respected. These libraries are private 358 and not yet built by default, so renumbering them should be a 359 non-issue. However, unclean source trees will yield broken test 360 programs once the operator executes "make delete-old-libs" after a 361 "make installworld". 362 363 Additionally, the atf-sh binary was made private by moving it into 364 /usr/libexec/. Already-built shell test programs will keep the 365 path to the old binary so they will break after "make delete-old" 366 is run. 367 368 If you are using WITH_TESTS=yes (not the default), wipe the object 369 tree and rebuild from scratch to prevent spurious test failures. 370 This is only needed once: the misnumbered libraries and misplaced 371 binaries have been added to OptionalObsoleteFiles.inc so they will 372 be removed during a clean upgrade. 373 37420140814: 375 The ixgbe tunables now match their sysctl counterparts, for example: 376 hw.ixgbe.enable_aim => hw.ix.enable_aim 377 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 378 37920140801: 380 The NFSv4.1 server committed by r269398 changes the internal 381 function call interfaces used between the NFS and krpc modules. 382 As such, __FreeBSD_version was bumped. 383 38420140729: 385 The default unbound configuration has been modified to address 386 issues with reverse lookups on networks that use private 387 address ranges. If you use the local_unbound service, run 388 "service local_unbound setup" as root to regenerate your 389 configuration, then "service local_unbound reload" to load the 390 new configuration. 391 39220140717: 393 It is no longer necessary to include the dwarf version in your DEBUG 394 options in your kernel config file. The bug that required it to be 395 placed in the config file has bene fixed. DEBUG should now just 396 contain -g. The build system will automatically update things 397 to do the right thing. 398 39920140715: 400 Several ABI breaking changes were merged to CTL and new iSCSI code. 401 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 402 iscsictl need to be rebuilt to work with a new kernel. 403 40420140708: 405 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 406 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 407 which differs from the behaviour controlled by this knob.) 408 40920140608: 410 On i386 and amd64 systems, the onifconsole flag is now set by default 411 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 412 as a login TTY if it is set in the bootloader as an active kernel 413 console. No changes in behavior should result otherwise. To revert to 414 the previous behavior, set ttyu0 to "off" in /etc/ttys. 415 41620140512: 417 Clang and llvm have been upgraded to 3.4.1 release. 418 41920140321: 420 Clang and llvm have been upgraded to 3.4 release. 421 42220140306: 423 If a Makefile in a tests/ directory was auto-generating a Kyuafile 424 instead of providing an explicit one, this would prevent such 425 Makefile from providing its own Kyuafile in the future during 426 NO_CLEAN builds. This has been fixed in the Makefiles but manual 427 intervention is needed to clean an objdir if you use NO_CLEAN: 428 # find /usr/obj -name Kyuafile | xargs rm -f 429 43020140303: 431 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 432 capability mode support. Please note that enabling the feature in 433 kernel is still highly recommended. 434 43520140227: 436 OpenSSH is now built with sandbox support, and will use sandbox as 437 the default privilege separation method. This requires Capsicum 438 capability mode support in kernel. 439 44020140216: 441 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 442 been deprecated and will not be part of FreeBSD 11.0 and later 443 releases. If you use this driver, please consider switching to 444 the nfe(4) driver instead. 445 44620140120: 447 10.0-RELEASE. 448 44920131216: 450 The behavior of gss_pseudo_random() for the krb5 mechanism 451 has changed, for applications requesting a longer random string 452 than produced by the underlying enctype's pseudo-random() function. 453 In particular, the random string produced from a session key of 454 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 455 be different at the 17th octet and later, after this change. 456 The counter used in the PRF+ construction is now encoded as a 457 big-endian integer in accordance with RFC 4402. 458 __FreeBSD_version is bumped to 1000701. 459 46020131108: 461 The WITHOUT_ATF build knob has been removed and its functionality 462 has been subsumed into the more generic WITHOUT_TESTS. If you were 463 using the former to disable the build of the ATF libraries, you 464 should change your settings to use the latter. 465 46620131031: 467 The default version of mtree is nmtree which is obtained from 468 NetBSD. The output is generally the same, but may vary 469 slightly. If you found you need identical output adding 470 "-F freebsd9" to the command line should do the trick. For the 471 time being, the old mtree is available as fmtree. 472 47320131014: 474 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 475 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 476 1.1.4_8 and verify bsdyml not linked in, before running "make 477 delete-old-libs": 478 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 479 or 480 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 481 48220131010: 483 The rc.d/jail script has been updated to support jail(8) 484 configuration file. The "jail_<jname>_*" rc.conf(5) variables 485 for per-jail configuration are automatically converted to 486 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 487 This is transparently backward compatible. See below about some 488 incompatibilities and rc.conf(5) manual page for more details. 489 490 These variables are now deprecated in favor of jail(8) configuration 491 file. One can use "rc.d/jail config <jname>" command to generate 492 a jail(8) configuration file in /var/run/jail.<jname>.conf without 493 running the jail(8) utility. The default pathname of the 494 configuration file is /etc/jail.conf and can be specified by 495 using $jail_conf or $jail_<jname>_conf variables. 496 497 Please note that jail_devfs_ruleset accepts an integer at 498 this moment. Please consider to rewrite the ruleset name 499 with an integer. 500 50120130930: 502 BIND has been removed from the base system. If all you need 503 is a local resolver, simply enable and start the local_unbound 504 service instead. Otherwise, several versions of BIND are 505 available in the ports tree. The dns/bind99 port is one example. 506 507 With this change, nslookup(1) and dig(1) are no longer in the base 508 system. Users should instead use host(1) and drill(1) which are 509 in the base system. Alternatively, nslookup and dig can 510 be obtained by installing the dns/bind-tools port. 511 51220130916: 513 With the addition of unbound(8), a new unbound user is now 514 required during installworld. "mergemaster -p" can be used to 515 add the user prior to installworld, as documented in the handbook. 516 51720130911: 518 OpenSSH is now built with DNSSEC support, and will by default 519 silently trust signed SSHFP records. This can be controlled with 520 the VerifyHostKeyDNS client configuration setting. DNSSEC support 521 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 522 52320130906: 524 The GNU Compiler Collection and C++ standard library (libstdc++) 525 are no longer built by default on platforms where clang is the system 526 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 527 options in src.conf. 528 52920130905: 530 The PROCDESC kernel option is now part of the GENERIC kernel 531 configuration and is required for the rwhod(8) to work. 532 If you are using custom kernel configuration, you should include 533 'options PROCDESC'. 534 53520130905: 536 The API and ABI related to the Capsicum framework was modified 537 in backward incompatible way. The userland libraries and programs 538 have to be recompiled to work with the new kernel. This includes the 539 following libraries and programs, but the whole buildworld is 540 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 541 kdump, procstat, rwho, rwhod, uniq. 542 54320130903: 544 AES-NI intrinsic support has been added to gcc. The AES-NI module 545 has been updated to use this support. A new gcc is required to build 546 the aesni module on both i386 and amd64. 547 54820130821: 549 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 550 Thus "device padlock_rng" and "device rdrand_rng" should be 551 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 552 55320130813: 554 WITH_ICONV has been split into two feature sets. WITH_ICONV now 555 enables just the iconv* functionality and is now on by default. 556 WITH_LIBICONV_COMPAT enables the libiconv api and link time 557 compatability. Set WITHOUT_ICONV to build the old way. 558 If you have been using WITH_ICONV before, you will very likely 559 need to turn on WITH_LIBICONV_COMPAT. 560 56120130806: 562 INVARIANTS option now enables DEBUG for code with OpenSolaris and 563 Illumos origin, including ZFS. If you have INVARIANTS in your 564 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 565 explicitly. 566 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 567 locks if WITNESS option was set. Because that generated a lot of 568 witness(9) reports and all of them were believed to be false 569 positives, this is no longer done. New option OPENSOLARIS_WITNESS 570 can be used to achieve the previous behavior. 571 57220130806: 573 Timer values in IPv6 data structures now use time_uptime instead 574 of time_second. Although this is not a user-visible functional 575 change, userland utilities which directly use them---ndp(8), 576 rtadvd(8), and rtsold(8) in the base system---need to be updated 577 to r253970 or later. 578 57920130802: 580 find -delete can now delete the pathnames given as arguments, 581 instead of only files found below them or if the pathname did 582 not contain any slashes. Formerly, the following error message 583 would result: 584 585 find: -delete: <path>: relative path potentially not safe 586 587 Deleting the pathnames given as arguments can be prevented 588 without error messages using -mindepth 1 or by changing 589 directory and passing "." as argument to find. This works in the 590 old as well as the new version of find. 591 59220130726: 593 Behavior of devfs rules path matching has been changed. 594 Pattern is now always matched against fully qualified devfs 595 path and slash characters must be explicitly matched by 596 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 597 subdirectories must be reviewed. 598 59920130716: 600 The default ARM ABI has changed to the ARM EABI. The old ABI is 601 incompatible with the ARM EABI and all programs and modules will 602 need to be rebuilt to work with a new kernel. 603 604 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 605 606 NOTE: Support for the old ABI will be removed in the future and 607 users are advised to upgrade. 608 60920130709: 610 pkg_install has been disconnected from the build if you really need it 611 you should add WITH_PKGTOOLS in your src.conf(5). 612 61320130709: 614 Most of network statistics structures were changed to be able 615 keep 64-bits counters. Thus all tools, that work with networking 616 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 617 61820130618: 619 Fix a bug that allowed a tracing process (e.g. gdb) to write 620 to a memory-mapped file in the traced process's address space 621 even if neither the traced process nor the tracing process had 622 write access to that file. 623 62420130615: 625 CVS has been removed from the base system. An exact copy 626 of the code is available from the devel/cvs port. 627 62820130613: 629 Some people report the following error after the switch to bmake: 630 631 make: illegal option -- J 632 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 633 ... 634 *** [buildworld] Error code 2 635 636 this likely due to an old instance of make in 637 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 638 which src/Makefile will use that blindly, if it exists, so if 639 you see the above error: 640 641 rm -rf `make -V MAKEPATH` 642 643 should resolve it. 644 64520130516: 646 Use bmake by default. 647 Whereas before one could choose to build with bmake via 648 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 649 make. The goal is to remove these knobs for 10-RELEASE. 650 651 It is worth noting that bmake (like gmake) treats the command 652 line as the unit of failure, rather than statements within the 653 command line. Thus '(cd some/where && dosomething)' is safer 654 than 'cd some/where; dosomething'. The '()' allows consistent 655 behavior in parallel build. 656 65720130429: 658 Fix a bug that allows NFS clients to issue READDIR on files. 659 66020130426: 661 The WITHOUT_IDEA option has been removed because 662 the IDEA patent expired. 663 66420130426: 665 The sysctl which controls TRIM support under ZFS has been renamed 666 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 667 enabled by default. 668 66920130425: 670 The mergemaster command now uses the default MAKEOBJDIRPREFIX 671 rather than creating it's own in the temporary directory in 672 order allow access to bootstrapped versions of tools such as 673 install and mtree. When upgrading from version of FreeBSD where 674 the install command does not support -l, you will need to 675 install a new mergemaster command if mergemaster -p is required. 676 This can be accomplished with the command (cd src/usr.sbin/mergemaster 677 && make install). 678 67920130404: 680 Legacy ATA stack, disabled and replaced by new CAM-based one since 681 FreeBSD 9.0, completely removed from the sources. Kernel modules 682 atadisk and atapi*, user-level tools atacontrol and burncd are 683 removed. Kernel option `options ATA_CAM` is now permanently enabled 684 and removed. 685 68620130319: 687 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 688 and socketpair(2). Software, in particular Kerberos, may 689 automatically detect and use these during building. The resulting 690 binaries will not work on older kernels. 691 69220130308: 693 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 694 information, see the respective 20130304 entry). 695 69620130304: 697 Recent commits to callout(9) changed the size of struct callout, 698 so the KBI is probably heavily disturbed. Also, some functions 699 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 700 by macros. Every kernel module using it won't load, so rebuild 701 is requested. 702 703 The ctl device has been re-enabled in GENERIC for i386 and amd64, 704 but does not initialize by default (because of the new CTL_DISABLE 705 option) to save memory. To re-enable it, remove the CTL_DISABLE 706 option from the kernel config file or set kern.cam.ctl.disable=0 707 in /boot/loader.conf. 708 70920130301: 710 The ctl device has been disabled in GENERIC for i386 and amd64. 711 This was done due to the extra memory being allocated at system 712 initialisation time by the ctl driver which was only used if 713 a CAM target device was created. This makes a FreeBSD system 714 unusable on 128MB or less of RAM. 715 71620130208: 717 A new compression method (lz4) has been merged to -HEAD. Please 718 refer to zpool-features(7) for more information. 719 720 Please refer to the "ZFS notes" section of this file for information 721 on upgrading boot ZFS pools. 722 72320130129: 724 A BSD-licensed patch(1) variant has been added and is installed 725 as bsdpatch, being the GNU version the default patch. 726 To inverse the logic and use the BSD-licensed one as default, 727 while having the GNU version installed as gnupatch, rebuild 728 and install world with the WITH_BSD_PATCH knob set. 729 73020130121: 731 Due to the use of the new -l option to install(1) during build 732 and install, you must take care not to directly set the INSTALL 733 make variable in your /etc/make.conf, /etc/src.conf, or on the 734 command line. If you wish to use the -C flag for all installs 735 you may be able to add INSTALL+=-C to /etc/make.conf or 736 /etc/src.conf. 737 73820130118: 739 The install(1) option -M has changed meaning and now takes an 740 argument that is a file or path to append logs to. In the 741 unlikely event that -M was the last option on the command line 742 and the command line contained at least two files and a target 743 directory the first file will have logs appended to it. The -M 744 option served little practical purpose in the last decade so its 745 use is expected to be extremely rare. 746 74720121223: 748 After switching to Clang as the default compiler some users of ZFS 749 on i386 systems started to experience stack overflow kernel panics. 750 Please consider using 'options KSTACK_PAGES=4' in such configurations. 751 75220121222: 753 GEOM_LABEL now mangles label names read from file system metadata. 754 Mangling affect labels containing spaces, non-printable characters, 755 '%' or '"'. Device names in /etc/fstab and other places may need to 756 be updated. 757 75820121217: 759 By default, only the 10 most recent kernel dumps will be saved. To 760 restore the previous behaviour (no limit on the number of kernel dumps 761 stored in the dump directory) add the following line to /etc/rc.conf: 762 763 savecore_flags="" 764 76520121201: 766 With the addition of auditdistd(8), a new auditdistd user is now 767 required during installworld. "mergemaster -p" can be used to 768 add the user prior to installworld, as documented in the handbook. 769 77020121117: 771 The sin6_scope_id member variable in struct sockaddr_in6 is now 772 filled by the kernel before passing the structure to the userland via 773 sysctl or routing socket. This means the KAME-specific embedded scope 774 id in sin6_addr.s6_addr[2] is always cleared in userland application. 775 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 776 __FreeBSD_version is bumped to 1000025. 777 77820121105: 779 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 780 This means that the world and kernel will be compiled with clang 781 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 782 and /usr/bin/cpp. To disable this behavior and revert to building 783 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 784 of current may need to bootstrap WITHOUT_CLANG first if the clang 785 build fails (its compatibility window doesn't extend to the 9 stable 786 branch point). 787 78820121102: 789 The IPFIREWALL_FORWARD kernel option has been removed. Its 790 functionality now turned on by default. 791 79220121023: 793 The ZERO_COPY_SOCKET kernel option has been removed and 794 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 795 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 796 mechanism which is not safe and may result in kernel crashes. 797 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 798 driver supports disposeable external page sized mbuf storage. 799 Proper replacements for both zero-copy mechanisms are under 800 consideration and will eventually lead to complete removal 801 of the two kernel options. 802 80320121023: 804 The IPv4 network stack has been converted to network byte 805 order. The following modules need to be recompiled together 806 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 807 pf(4), ipfw(4), ng_ipfw(4), stf(4). 808 80920121022: 810 Support for non-MPSAFE filesystems was removed from VFS. The 811 VFS_VERSION was bumped, all filesystem modules shall be 812 recompiled. 813 81420121018: 815 All the non-MPSAFE filesystems have been disconnected from 816 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 817 portalfs, smbfs, xfs. 818 81920121016: 820 The interface cloning API and ABI has changed. The following 821 modules need to be recompiled together with kernel: 822 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 823 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 824 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 825 82620121015: 827 The sdhci driver was split in two parts: sdhci (generic SD Host 828 Controller logic) and sdhci_pci (actual hardware driver). 829 No kernel config modifications are required, but if you 830 load sdhc as a module you must switch to sdhci_pci instead. 831 83220121014: 833 Import the FUSE kernel and userland support into base system. 834 83520121013: 836 The GNU sort(1) program has been removed since the BSD-licensed 837 sort(1) has been the default for quite some time and no serious 838 problems have been reported. The corresponding WITH_GNU_SORT 839 knob has also gone. 840 84120121006: 842 The pfil(9) API/ABI for AF_INET family has been changed. Packet 843 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 844 with new kernel. 845 84620121001: 847 The net80211(4) ABI has been changed to allow for improved driver 848 PS-POLL and power-save support. All wireless drivers need to be 849 recompiled to work with the new kernel. 850 85120120913: 852 The random(4) support for the VIA hardware random number 853 generator (`PADLOCK') is no longer enabled unconditionally. 854 Add the padlock_rng device in the custom kernel config if 855 needed. The GENERIC kernels on i386 and amd64 do include the 856 device, so the change only affects the custom kernel 857 configurations. 858 85920120908: 860 The pf(4) packet filter ABI has been changed. pfctl(8) and 861 snmp_pf module need to be recompiled to work with new kernel. 862 86320120828: 864 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 865 to -HEAD. Pools that have empty_bpobj in active state can not be 866 imported read-write with ZFS implementations that do not support 867 this feature. For more information read the zpool-features(5) 868 manual page. 869 87020120727: 871 The sparc64 ZFS loader has been changed to no longer try to auto- 872 detect ZFS providers based on diskN aliases but now requires these 873 to be explicitly listed in the OFW boot-device environment variable. 874 87520120712: 876 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 877 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 878 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 879 88020120712: 881 The following sysctls and tunables have been renamed for consistency 882 with other variables: 883 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 884 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 885 88620120628: 887 The sort utility has been replaced with BSD sort. For now, GNU sort 888 is also available as "gnusort" or the default can be set back to 889 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 890 installed as "bsdsort". 891 89220120611: 893 A new version of ZFS (pool version 5000) has been merged to -HEAD. 894 Starting with this version the old system of ZFS pool versioning 895 is superseded by "feature flags". This concept enables forward 896 compatibility against certain future changes in functionality of ZFS 897 pools. The first read-only compatible "feature flag" for ZFS pools 898 is named "com.delphix:async_destroy". For more information 899 read the new zpool-features(5) manual page. 900 Please refer to the "ZFS notes" section of this file for information 901 on upgrading boot ZFS pools. 902 90320120417: 904 The malloc(3) implementation embedded in libc now uses sources imported 905 as contrib/jemalloc. The most disruptive API change is to 906 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 907 delete it prior to installworld, and optionally re-create it using the 908 new format after rebooting. See malloc.conf(5) for details 909 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 910 NAMESPACE section). 911 91220120328: 913 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 914 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 915 now spelled mips. This is to aid compatibility with third-party 916 software that expects this naming scheme in uname(3). Little-endian 917 settings are unchanged. If you are updating a big-endian mips64 machine 918 from before this change, you may need to set MACHINE_ARCH=mips64 in 919 your environment before the new build system will recognize your machine. 920 92120120306: 922 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 923 platforms. 924 92520120229: 926 Now unix domain sockets behave "as expected" on nullfs(5). Previously 927 nullfs(5) did not pass through all behaviours to the underlying layer, 928 as a result if we bound to a socket on the lower layer we could connect 929 only to the lower path; if we bound to the upper layer we could connect 930 only to the upper path. The new behavior is one can connect to both the 931 lower and the upper paths regardless what layer path one binds to. 932 93320120211: 934 The getifaddrs upgrade path broken with 20111215 has been restored. 935 If you have upgraded in between 20111215 and 20120209 you need to 936 recompile libc again with your kernel. You still need to recompile 937 world to be able to configure CARP but this restriction already 938 comes from 20111215. 939 94020120114: 941 The set_rcvar() function has been removed from /etc/rc.subr. All 942 base and ports rc.d scripts have been updated, so if you have a 943 port installed with a script in /usr/local/etc/rc.d you can either 944 hand-edit the rcvar= line, or reinstall the port. 945 946 An easy way to handle the mass-update of /etc/rc.d: 947 rm /etc/rc.d/* && mergemaster -i 948 94920120109: 950 panic(9) now stops other CPUs in the SMP systems, disables interrupts 951 on the current CPU and prevents other threads from running. 952 This behavior can be reverted using the kern.stop_scheduler_on_panic 953 tunable/sysctl. 954 The new behavior can be incompatible with kern.sync_on_panic. 955 95620111215: 957 The carp(4) facility has been changed significantly. Configuration 958 of the CARP protocol via ifconfig(8) has changed, as well as format 959 of CARP events submitted to devd(8) has changed. See manual pages 960 for more information. The arpbalance feature of carp(4) is currently 961 not supported anymore. 962 963 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 964 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 965 need to be recompiled. 966 96720111122: 968 The acpi_wmi(4) status device /dev/wmistat has been renamed to 969 /dev/wmistat0. 970 97120111108: 972 The option VFS_ALLOW_NONMPSAFE option has been added in order to 973 explicitely support non-MPSAFE filesystems. 974 It is on by default for all supported platform at this present 975 time. 976 97720111101: 978 The broken amd(4) driver has been replaced with esp(4) in the amd64, 979 i386 and pc98 GENERIC kernel configuration files. 980 98120110930: 982 sysinstall has been removed 983 98420110923: 985 The stable/9 branch created in subversion. This corresponds to the 986 RELENG_9 branch in CVS. 987 98820110913: 989 This commit modifies vfs_register() so that it uses a hash 990 calculation to set vfc_typenum, which is enabled by default. 991 The first time a system is booted after this change, the 992 vfc_typenum values will change for all file systems. The 993 main effect of this is a change to the NFS server file handles 994 for file systems that use vfc_typenum in their fsid, such as ZFS. 995 It will, however, prevent vfc_typenum from changing when file 996 systems are loaded in a different order for subsequent reboots. 997 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 998 until you are ready to remount all NFS clients after a reboot. 999 100020110828: 1001 Bump the shared library version numbers for libraries that 1002 do not use symbol versioning, have changed the ABI compared 1003 to stable/8 and which shared library version was not bumped. 1004 Done as part of 9.0-RELEASE cycle. 1005 100620110815: 1007 During the merge of Capsicum features, the fget(9) KPI was modified. 1008 This may require the rebuilding of out-of-tree device drivers -- 1009 issues have been reported specifically with the nVidia device driver. 1010 __FreeBSD_version is bumped to 900041. 1011 1012 Also, there is a period between 20110811 and 20110814 where the 1013 special devices /dev/{stdin,stdout,stderr} did not work correctly. 1014 Building world from a kernel during that window may not work. 1015 101620110628: 1017 The packet filter (pf) code has been updated to OpenBSD 4.5. 1018 You need to update userland tools to be in sync with kernel. 1019 This update breaks backward compatibility with earlier pfsync(4) 1020 versions. Care must be taken when updating redundant firewall setups. 1021 102220110608: 1023 The following sysctls and tunables are retired on x86 platforms: 1024 machdep.hlt_cpus 1025 machdep.hlt_logical_cpus 1026 The following sysctl is retired: 1027 machdep.hyperthreading_allowed 1028 The sysctls were supposed to provide a way to dynamically offline and 1029 online selected CPUs on x86 platforms, but the implementation has not 1030 been reliable especially with SCHED_ULE scheduler. 1031 machdep.hyperthreading_allowed tunable is still available to ignore 1032 hyperthreading CPUs at OS level. 1033 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 1034 where X is an APIC ID of a CPU. Be advised, though, that disabling 1035 CPUs in non-uniform fashion will result in non-uniform topology and 1036 may lead to sub-optimal system performance with SCHED_ULE, which is 1037 a default scheduler. 1038 103920110607: 1040 cpumask_t type is retired and cpuset_t is used in order to describe 1041 a mask of CPUs. 1042 104320110531: 1044 Changes to ifconfig(8) for dynamic address family detection mandate 1045 that you are running a kernel of 20110525 or later. Make sure to 1046 follow the update procedure to boot a new kernel before installing 1047 world. 1048 104920110513: 1050 Support for sun4v architecture is officially dropped 1051 105220110503: 1053 Several KPI breaking changes have been committed to the mii(4) layer, 1054 the PHY drivers and consequently some Ethernet drivers using mii(4). 1055 This means that miibus.ko and the modules of the affected Ethernet 1056 drivers need to be recompiled. 1057 1058 Note to kernel developers: Given that the OUI bit reversion problem 1059 was fixed as part of these changes all mii(4) commits related to OUIs, 1060 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1061 handling, no longer can be merged verbatim to stable/8 and previous 1062 branches. 1063 106420110430: 1065 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1066 into their kernel configurations along with 'device pci'. 1067 106820110427: 1069 The default NFS client is now the new NFS client, so fstype "newnfs" 1070 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1071 Although mounts via fstype "nfs" will usually work without userland 1072 changes, it is recommended that the mount(8) and mount_nfs(8) 1073 commands be rebuilt from sources and that a link to mount_nfs called 1074 mount_oldnfs be created. The new client is compiled into the 1075 kernel with "options NFSCL" and this is needed for diskless root 1076 file systems. The GENERIC kernel configs have been changed to use 1077 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1078 To use the regular/old client, you can "mount -t oldnfs ...". For 1079 a diskless root file system, you must also include a line like: 1080 1081 vfs.root.mountfrom="oldnfs:" 1082 1083 in the boot/loader.conf on the root fs on the NFS server to make 1084 a diskless root fs use the old client. 1085 108620110424: 1087 The GENERIC kernels for all architectures now default to the new 1088 CAM-based ATA stack. It means that all legacy ATA drivers were 1089 removed and replaced by respective CAM drivers. If you are using 1090 ATA device names in /etc/fstab or other places, make sure to update 1091 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1092 where 'Y's are the sequential numbers starting from zero for each type 1093 in order of detection, unless configured otherwise with tunables, 1094 see cam(4)). There will be symbolic links created in /dev/ to map 1095 old adX devices to the respective adaY. They should provide basic 1096 compatibility for file systems mounting in most cases, but they do 1097 not support old user-level APIs and do not have respective providers 1098 in GEOM. Consider using updated management tools with new device names. 1099 1100 It is possible to load devices ahci, ata, siis and mvs as modules, 1101 but option ATA_CAM should remain in kernel configuration to make ata 1102 module work as CAM driver supporting legacy ATA controllers. Device ata 1103 still can be used in modular fashion (atacore + ...). Modules atadisk 1104 and atapi* are not used and won't affect operation in ATA_CAM mode. 1105 Note that to use CAM-based ATA kernel should include CAM devices 1106 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1107 them are parts of the cam module. 1108 1109 ataraid(4) functionality is now supported by the RAID GEOM class. 1110 To use it you can load geom_raid kernel module and use graid(8) tool 1111 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1112 1113 No kernel config options or code have been removed, so if a problem 1114 arises, please report it and optionally revert to the old ATA stack. 1115 In order to do it you can remove from the kernel config: 1116 options ATA_CAM 1117 device ahci 1118 device mvs 1119 device siis 1120 , and instead add back: 1121 device atadisk # ATA disk drives 1122 device ataraid # ATA RAID drives 1123 device atapicd # ATAPI CDROM drives 1124 device atapifd # ATAPI floppy drives 1125 device atapist # ATAPI tape drives 1126 112720110423: 1128 The default NFS server has been changed to the new server, which 1129 was referred to as the experimental server. If you need to switch 1130 back to the old NFS server, you must now put the "-o" option on 1131 both the mountd and nfsd commands. This can be done using the 1132 mountd_flags and nfs_server_flags rc.conf variables until an 1133 update to the rc scripts is committed, which is coming soon. 1134 113520110418: 1136 The GNU Objective-C runtime library (libobjc), and other Objective-C 1137 related components have been removed from the base system. If you 1138 require an Objective-C library, please use one of the available ports. 1139 114020110331: 1141 ath(4) has been split into bus- and device- modules. if_ath contains 1142 the HAL, the TX rate control and the network device code. if_ath_pci 1143 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1144 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1145 in order to use ath on everything else. 1146 1147 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1148 need to load if_ath and if_ath_pci for ath(4) operation. 1149 115020110314: 1151 As part of the replacement of sysinstall, the process of building 1152 release media has changed significantly. For details, please re-read 1153 release(7), which has been updated to reflect the new build process. 1154 115520110218: 1156 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1157 is the last available version under GPLv2. It brings a number of new 1158 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1159 4.1 and SSE 4.2), better support for powerpc64, a number of new 1160 directives, and lots of other small improvements. See the ChangeLog 1161 file in contrib/binutils for the full details. 1162 116320110218: 1164 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1165 compliant, and will now use half of hash for authentication. 1166 This will break interoperability with all stacks (including all 1167 actual FreeBSD versions) who implement 1168 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1169 authentication). 1170 The only workaround with such peers is to use another HMAC 1171 algorithm for IPsec ("phase 2") authentication. 1172 117320110207: 1174 Remove the uio_yield prototype and symbol. This function has 1175 been misnamed since it was introduced and should not be 1176 globally exposed with this name. The equivalent functionality 1177 is now available using kern_yield(curthread->td_user_pri). 1178 The function remains undocumented. 1179 118020110112: 1181 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1182 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1183 for scalar sysctls is defined but disabled. Code that needs 1184 UQUAD to pass the type checking that must compile on older 1185 systems where the define is not present can check against 1186 __FreeBSD_version >= 900030. 1187 1188 The system dialog(1) has been replaced with a new version previously 1189 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1190 with the previous version, but the libdialog associated with it has 1191 a largely incompatible API. As such, the original version of libdialog 1192 will be kept temporarily as libodialog, until its base system consumers 1193 are replaced or updated. Bump __FreeBSD_version to 900030. 1194 119520110103: 1196 If you are trying to run make universe on a -stable system, and you get 1197 the following warning: 1198 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1199 unknown. config(8) likely too old." 1200 or something similar to it, then you must upgrade your -stable system 1201 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1202 stable/8) or build the config from the latest stable/8 branch and 1203 install it on your system. 1204 1205 Prior to this date, building a current universe on 8-stable system from 1206 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1207 error in the first kernel build phase. A new config on those old 1208 systems will fix that problem for older versions of -current. 1209 121020101228: 1211 The TCP stack has been modified to allow Khelp modules to interact with 1212 it via helper hook points and store per-connection data in the TCP 1213 control block. Bump __FreeBSD_version to 900029. User space tools that 1214 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1215 be recompiled. 1216 121720101114: 1218 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1219 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1220 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1221 to take advantage of it instead of using custom implementations. This 1222 means that these drivers now no longer unconditionally advertise 1223 support for flow control but only do so if flow control is a selected 1224 media option. This was implemented in the generic support that way in 1225 order to allow flow control to be switched on and off via ifconfig(8) 1226 with the PHY specific default to typically off in order to protect 1227 from unwanted effects. Consequently, if you used flow control with 1228 one of the above mentioned drivers you now need to explicitly enable 1229 it, for example via: 1230 ifconfig bge0 media auto mediaopt flowcontrol 1231 1232 Along with the above mentioned changes generic support for setting 1233 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1234 e1000phy(4) as well as ip1000phy(4) have been converted to take 1235 advantage of it. This means that these drivers now no longer take the 1236 link0 parameter for selecting master mode but the master media option 1237 has to be used instead, for example like in the following: 1238 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1239 1240 Selection of master mode now is also available with all other PHY 1241 drivers supporting 1000baseT. 1242 124320101111: 1244 The TCP stack has received a significant update to add support for 1245 modularised congestion control and generally improve the clarity of 1246 congestion control decisions. Bump __FreeBSD_version to 900025. User 1247 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1248 sockstat) need to be recompiled. 1249 125020101002: 1251 The man(1) utility has been replaced by a new version that no longer 1252 uses /etc/manpath.config. Please consult man.conf(5) for how to 1253 migrate local entries to the new format. 1254 125520100928: 1256 The copyright strings printed by login(1) and sshd(8) at the time of a 1257 new connection have been removed to follow other operating systems and 1258 upstream sshd. 1259 126020100915: 1261 A workaround for a fixed ld bug has been removed in kernel code, 1262 so make sure that your system ld is built from sources after 1263 revision 210245 from 2010-07-19 (r211583 if building head kernel 1264 on stable/8, r211584 for stable/7; both from 2010-08-21). 1265 A symptom of incorrect ld version is different addresses for 1266 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1267 126820100913: 1269 The $ipv6_prefer variable in rc.conf(5) has been split into 1270 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1271 1272 The $ip6addrctl_policy is a variable to choose a pre-defined 1273 address selection policy set by ip6addrctl(8). A value 1274 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1275 default is "AUTO". 1276 1277 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1278 flag (see an entry of 20090926) is set on an interface with no 1279 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1280 security reason. If you want IPv6 link-local address on all 1281 interfaces by default, set this to "YES". 1282 1283 The old ipv6_prefer="YES" is equivalent to 1284 ipv6_activate_all_interfaces="YES" and 1285 ip6addrctl_policy="ipv6_prefer". 1286 128720100913: 1288 DTrace has grown support for userland tracing. Due to this, DTrace is 1289 now i386 and amd64 only. 1290 dtruss(1) is now installed by default on those systems and a new 1291 kernel module is needed for userland tracing: fasttrap. 1292 No changes to your kernel config file are necessary to enable 1293 userland tracing, but you might consider adding 'STRIP=' and 1294 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1295 to have informative userland stack traces in DTrace (ustack). 1296 129720100725: 1298 The acpi_aiboost(4) driver has been removed in favor of the new 1299 aibs(4) driver. You should update your kernel configuration file. 1300 130120100722: 1302 BSD grep has been imported to the base system and it is built by 1303 default. It is completely BSD licensed, highly GNU-compatible, uses 1304 less memory than its GNU counterpart and has a small codebase. 1305 However, it is slower than its GNU counterpart, which is mostly 1306 noticeable for larger searches, for smaller ones it is measurable 1307 but not significant. The reason is complex, the most important factor 1308 is that we lack a modern and efficient regex library and GNU 1309 overcomes this by optimizing the searches internally. Future work 1310 on improving the regex performance is planned, for the meantime, 1311 users that need better performance, can build GNU grep instead by 1312 setting the WITH_GNU_GREP knob. 1313 131420100713: 1315 Due to the import of powerpc64 support, all existing powerpc kernel 1316 configuration files must be updated with a machine directive like this: 1317 machine powerpc powerpc 1318 1319 In addition, an updated config(8) is required to build powerpc kernels 1320 after this change. 1321 132220100713: 1323 A new version of ZFS (version 15) has been merged to -HEAD. 1324 This version uses a python library for the following subcommands: 1325 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1326 For full functionality of these commands the following port must 1327 be installed: sysutils/py-zfs 1328 132920100429: 1330 'vm_page's are now hashed by physical address to an array of mutexes. 1331 Currently this is only used to serialize access to hold_count. Over 1332 time the page queue mutex will be peeled away. This changes the size 1333 of pmap on every architecture. And requires all callers of vm_page_hold 1334 and vm_page_unhold to be updated. 1335 133620100402: 1337 WITH_CTF can now be specified in src.conf (not recommended, there 1338 are some problems with static executables), make.conf (would also 1339 affect ports which do not use GNU make and do not override the 1340 compile targets) or in the kernel config (via "makeoptions 1341 WITH_CTF=yes"). 1342 When WITH_CTF was specified there before this was silently ignored, 1343 so make sure that WITH_CTF is not used in places which could lead 1344 to unwanted behavior. 1345 134620100311: 1347 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1348 to allow 32-bit compatibility on non-x86 platforms. All kernel 1349 configurations on amd64 and ia64 platforms using these options must 1350 be modified accordingly. 1351 135220100113: 1353 The utmp user accounting database has been replaced with utmpx, 1354 the user accounting interface standardized by POSIX. 1355 Unfortunately the semantics of utmp and utmpx don't match, 1356 making it practically impossible to support both interfaces. 1357 The user accounting database is used by tools like finger(1), 1358 last(1), talk(1), w(1) and ac(8). 1359 1360 All applications in the base system use utmpx. This means only 1361 local binaries (e.g. from the ports tree) may still use these 1362 utmp database files. These applications must be rebuilt to make 1363 use of utmpx. 1364 1365 After the system has been upgraded, it is safe to remove the old 1366 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1367 assuming their contents is of no importance anymore. Old wtmp 1368 databases can only be used by last(1) and ac(8) after they have 1369 been converted to the new format using wtmpcvt(1). 1370 137120100108: 1372 Introduce the kernel thread "deadlock resolver" (which can be enabled 1373 via the DEADLKRES option, see NOTES for more details) and the 1374 sleepq_type() function for sleepqueues. 1375 137620091202: 1377 The rc.firewall and rc.firewall6 were unified, and 1378 rc.firewall6 and rc.d/ip6fw were removed. 1379 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1380 variables are obsoleted. Instead, the following new rc 1381 variables are added to rc.d/ipfw: 1382 1383 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1384 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1385 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1386 1387 The meanings correspond to the relevant IPv4 variables. 1388 138920091125: 1390 8.0-RELEASE. 1391 139220091113: 1393 The default terminal emulation for syscons(4) has been changed 1394 from cons25 to xterm on all platforms except pc98. This means 1395 that the /etc/ttys file needs to be updated to ensure correct 1396 operation of applications on the console. 1397 1398 The terminal emulation style can be toggled per window by using 1399 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1400 options can be used to change the compile-time default back to 1401 cons25. 1402 1403 To prevent graphical artifacts, make sure the TERM environment 1404 variable is set to match the terminal emulation that is being 1405 performed by syscons(4). 1406 140720091109: 1408 The layout of the structure ieee80211req_scan_result has changed. 1409 Applications that require wireless scan results (e.g. ifconfig(8)) 1410 from net80211 need to be recompiled. 1411 1412 Applications such as wpa_supplicant(8) may require a full world 1413 build without using NO_CLEAN in order to get synchronized with the 1414 new structure. 1415 141620091025: 1417 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1418 There's one kernel module for each firmware. Adding "device iwnfw" 1419 to the kernel configuration file means including all three firmware 1420 images inside the kernel. If you want to include just the one for 1421 your wireless card, use the devices iwn4965fw, iwn5000fw or 1422 iwn5150fw. 1423 142420090926: 1425 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1426 into rc.d/netif. The changes are the following: 1427 1428 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1429 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1430 Note that both variables need the "inet6" keyword at the head. 1431 1432 Do not set $ipv6_network_interfaces manually if you do not 1433 understand what you are doing. It is not needed in most cases. 1434 1435 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1436 they are obsolete. 1437 1438 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1439 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1440 1441 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1442 all configured interfaces have "inet6 accept_rtadv" in the 1443 $ifconfig_IF_ipv6. These are for backward compatibility. 1444 1445 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1446 functionality of interfaces with no corresponding 1447 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1448 and the default address selection policy of ip6addrctl(8) 1449 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1450 Note that if you want to configure IPv6 functionality on the 1451 disabled interfaces after boot, first you need to clear the flag by 1452 using ifconfig(8) like: 1453 1454 ifconfig em0 inet6 -ifdisabled 1455 1456 If YES, the default address selection policy is set as 1457 IPv6-preferred. 1458 1459 The default value of $ipv6_prefer is NO. 1460 1461 4. If your system need to receive Router Advertisement messages, 1462 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1463 scripts automatically invoke rtsol(8) when the interface becomes 1464 UP. The Router Advertisement messages are used for SLAAC 1465 (State-Less Address AutoConfiguration). 1466 146720090922: 1468 802.11s D3.03 support was committed. This is incompatible with the 1469 previous code, which was based on D3.0. 1470 147120090912: 1472 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1473 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1474 control whether accepting Router Advertisement messages or not. 1475 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1476 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1477 The ifconfig(8) utility now supports these flags. 1478 147920090910: 1480 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1481 mount(8) and -a option for df(1) to see them. 1482 148320090825: 1484 The old tunable hw.bus.devctl_disable has been superseded by 1485 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1486 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1487 is 1000. 1488 148920090813: 1490 Remove the option STOP_NMI. The default action is now to use NMI only 1491 for KDB via the newly introduced function stop_cpus_hard() and 1492 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1493 149420090803: 1495 The stable/8 branch created in subversion. This corresponds to the 1496 RELENG_8 branch in CVS. 1497 149820090719: 1499 Bump the shared library version numbers for all libraries that do not 1500 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1501 __FreeBSD_version to 800105. 1502 150320090714: 1504 Due to changes in the implementation of virtual network stack support, 1505 all network-related kernel modules must be recompiled. As this change 1506 breaks the ABI, bump __FreeBSD_version to 800104. 1507 150820090713: 1509 The TOE interface to the TCP syncache has been modified to remove 1510 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1511 The cxgb driver is the only TOE consumer affected by this change, and 1512 needs to be recompiled along with the kernel. As this change breaks 1513 the ABI, bump __FreeBSD_version to 800103. 1514 151520090712: 1516 Padding has been added to struct tcpcb, sackhint and tcpstat in 1517 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1518 maintaining the ABI. However, this change breaks the ABI, so bump 1519 __FreeBSD_version to 800102. User space tools that rely on the size of 1520 any of these structs (e.g. sockstat) need to be recompiled. 1521 152220090630: 1523 The NFS_LEGACYRPC option has been removed along with the old kernel 1524 RPC implementation that this option selected. Kernel configurations 1525 may need to be adjusted. 1526 152720090629: 1528 The network interface device nodes at /dev/net/<interface> have been 1529 removed. All ioctl operations can be performed the normal way using 1530 routing sockets. The kqueue functionality can generally be replaced 1531 with routing sockets. 1532 153320090628: 1534 The documentation from the FreeBSD Documentation Project (Handbook, 1535 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1536 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1537 153820090624: 1539 The ABI of various structures related to the SYSV IPC API have been 1540 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1541 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1542 800100. 1543 154420090622: 1545 Layout of struct vnet has changed as routing related variables were 1546 moved to their own Vimage module. Modules need to be recompiled. Bump 1547 __FreeBSD_version to 800099. 1548 154920090619: 1550 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1551 respectively. As long as no more than 16 groups per process are used, 1552 no changes should be visible. When more than 16 groups are used, old 1553 binaries may fail if they call getgroups() or getgrouplist() with 1554 statically sized storage. Recompiling will work around this, but 1555 applications should be modified to use dynamically allocated storage 1556 for group arrays as POSIX.1-2008 does not cap an implementation's 1557 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1558 1559 NFS and portalfs mounts may also be affected as the list of groups is 1560 truncated to 16. Users of NFS who use more than 16 groups, should 1561 take care that negative group permissions are not used on the exported 1562 file systems as they will not be reliable unless a GSSAPI based 1563 authentication method is used. 1564 156520090616: 1566 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1567 option compiles in the support for adaptive spinning for lockmgrs 1568 which want to enable it. The lockinit() function now accepts the flag 1569 LK_ADAPTIVE in order to make the lock object subject to adaptive 1570 spinning when both held in write and read mode. 1571 157220090613: 1573 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1574 changed. User applications that use this ioctl need to be rebuilt. 1575 157620090611: 1577 The layout of struct thread has changed. Kernel and modules need to 1578 be rebuilt. 1579 158020090608: 1581 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1582 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1583 158420090602: 1585 window(1) has been removed from the base system. It can now be 1586 installed from ports. The port is called misc/window. 1587 158820090601: 1589 The way we are storing and accessing `routing table' entries has 1590 changed. Programs reading the FIB, like netstat, need to be 1591 re-compiled. 1592 159320090601: 1594 A new netisr implementation has been added for FreeBSD 8. Network 1595 file system modules, such as igmp, ipdivert, and others, should be 1596 rebuilt. 1597 Bump __FreeBSD_version to 800096. 1598 159920090530: 1600 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1601 more valid. 1602 160320090530: 1604 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1605 Bump __FreeBSD_version to 800094. 1606 160720090529: 1608 Add mnt_xflag field to 'struct mount'. File system modules need to be 1609 rebuilt. 1610 Bump __FreeBSD_version to 800093. 1611 161220090528: 1613 The compiling option ADAPTIVE_SX has been retired while it has been 1614 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1615 The KPI for sx_init_flags() changes as accepting flags: 1616 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1617 been introduced in order to handle the reversed logic. 1618 Bump __FreeBSD_version to 800092. 1619 162020090527: 1621 Add support for hierarchical jails. Remove global securelevel. 1622 Bump __FreeBSD_version to 800091. 1623 162420090523: 1625 The layout of struct vnet_net has changed, therefore modules 1626 need to be rebuilt. 1627 Bump __FreeBSD_version to 800090. 1628 162920090523: 1630 The newly imported zic(8) produces a new format in the output. Please 1631 run tzsetup(8) to install the newly created data to /etc/localtime. 1632 163320090520: 1634 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1635 hw.usb.* and is now consistent again with previous releases. 1636 163720090520: 1638 802.11 monitor mode support was revised and driver api's were changed. 1639 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1640 of DLT_IEEE802_11. No user-visible data structures were changed but 1641 applications that use DLT_IEEE802_11 may require changes. 1642 Bump __FreeBSD_version to 800088. 1643 164420090430: 1645 The layout of the following structs has changed: sysctl_oid, 1646 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1647 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1648 panics may be experienced. World rebuild is required for 1649 correctly checking networking state from userland. 1650 Bump __FreeBSD_version to 800085. 1651 165220090429: 1653 MLDv2 and Source-Specific Multicast (SSM) have been merged 1654 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1655 The implementation of SSM within FreeBSD's IPv6 stack closely 1656 follows the IPv4 implementation. 1657 1658 For kernel developers: 1659 1660 * The most important changes are that the ip6_output() and 1661 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1662 and this lock has been downgraded to a non-recursive mutex. 1663 1664 * As with the changes to the IPv4 stack to support SSM, filtering 1665 of inbound multicast traffic must now be performed by transport 1666 protocols within the IPv6 stack. This does not apply to TCP and 1667 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1668 1669 * The KPIs used by IPv6 multicast are similar to those used by 1670 the IPv4 stack, with the following differences: 1671 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1672 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1673 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1674 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1675 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1676 for MLDv1 have an additional 'timer' argument which is used to 1677 jitter the initial membership report for the solicited-node 1678 multicast membership on-link. 1679 * This is not strictly needed for MLDv2, which already jitters 1680 its report transmissions. However, the 'timer' argument is 1681 preserved in case MLDv1 is active on the interface. 1682 1683 * The KAME linked-list based IPv6 membership implementation has 1684 been refactored to use a vector similar to that used by the IPv4 1685 stack. 1686 Code which maintains a list of its own multicast memberships 1687 internally, e.g. carp, has been updated to reflect the new 1688 semantics. 1689 1690 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1691 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1692 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1693 implementation constraint which needs to be addressed in HEAD. 1694 1695 For application developers: 1696 1697 * The changes are broadly similar to those made for the IPv4 1698 stack. 1699 1700 * The use of IPv4 and IPv6 multicast socket options on the same 1701 socket, using mapped addresses, HAS NOT been tested or supported. 1702 1703 * There are a number of issues with the implementation of various 1704 IPv6 multicast APIs which need to be resolved in the API surface 1705 before the implementation is fully compatible with KAME userland 1706 use, and these are mostly to do with interface index treatment. 1707 1708 * The literature available discusses the use of either the delta / ASM 1709 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1710 using setsourcefilter(3)/getsourcefilter(3). For more information 1711 please refer to RFC 3768, 'Socket Interface Extensions for 1712 Multicast Source Filters'. 1713 1714 * Applications which use the published RFC 3678 APIs should be fine. 1715 1716 For systems administrators: 1717 1718 * The mtest(8) utility has been refactored to support IPv6, in 1719 addition to IPv4. Interface addresses are no longer accepted 1720 as arguments, their names must be used instead. The utility 1721 will map the interface name to its first IPv4 address as 1722 returned by getifaddrs(3). 1723 1724 * The ifmcstat(8) utility has also been updated to print the MLDv2 1725 endpoint state and source filter lists via sysctl(3). 1726 1727 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1728 loopback of IPv6 multicast datagrams by default; it defaults to 1 1729 to preserve the existing behaviour. Disabling multicast loopback is 1730 recommended for optimal system performance. 1731 1732 * The IPv6 MROUTING code has been changed to examine this sysctl 1733 instead of attempting to perform a group lookup before looping 1734 back forwarded datagrams. 1735 1736 Bump __FreeBSD_version to 800084. 1737 173820090422: 1739 Implement low-level Bluetooth HCI API. 1740 Bump __FreeBSD_version to 800083. 1741 174220090419: 1743 The layout of struct malloc_type, used by modules to register new 1744 memory allocation types, has changed. Most modules will need to 1745 be rebuilt or panics may be experienced. 1746 Bump __FreeBSD_version to 800081. 1747 174820090415: 1749 Anticipate overflowing inp_flags - add inp_flags2. 1750 This changes most offsets in inpcb, so checking v4 connection 1751 state will require a world rebuild. 1752 Bump __FreeBSD_version to 800080. 1753 175420090415: 1755 Add an llentry to struct route and struct route_in6. Modules 1756 embedding a struct route will need to be recompiled. 1757 Bump __FreeBSD_version to 800079. 1758 175920090414: 1760 The size of rt_metrics_lite and by extension rtentry has changed. 1761 Networking administration apps will need to be recompiled. 1762 The route command now supports show as an alias for get, weighting 1763 of routes, sticky and nostick flags to alter the behavior of stateful 1764 load balancing. 1765 Bump __FreeBSD_version to 800078. 1766 176720090408: 1768 Do not use Giant for kbdmux(4) locking. This is wrong and 1769 apparently causing more problems than it solves. This will 1770 re-open the issue where interrupt handlers may race with 1771 kbdmux(4) in polling mode. Typical symptoms include (but 1772 not limited to) duplicated and/or missing characters when 1773 low level console functions (such as gets) are used while 1774 interrupts are enabled (for example geli password prompt, 1775 mountroot prompt etc.). Disabling kbdmux(4) may help. 1776 177720090407: 1778 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1779 kernel modules referencing any of the above need to be recompiled. 1780 Bump __FreeBSD_version to 800075. 1781 178220090320: 1783 GEOM_PART has become the default partition slicer for storage devices, 1784 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1785 introduces some changes: 1786 1787 MSDOS/EBR: the devices created from MSDOS extended partition entries 1788 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1789 to devices with offset-based names. fstabs may need to be modified. 1790 1791 BSD: the "geometry does not match label" warning is harmless in most 1792 cases but it points to problems in file system misalignment with 1793 disk geometry. The "c" partition is now implicit, covers the whole 1794 top-level drive and cannot be (mis)used by users. 1795 1796 General: Kernel dumps are now not allowed to be written to devices 1797 whose partition types indicate they are meant to be used for file 1798 systems (or, in case of MSDOS partitions, as something else than 1799 the "386BSD" type). 1800 1801 Most of these changes date approximately from 200812. 1802 180320090319: 1804 The uscanner(4) driver has been removed from the kernel. This follows 1805 Linux removing theirs in 2.6 and making libusb the default interface 1806 (supported by sane). 1807 180820090319: 1809 The multicast forwarding code has been cleaned up. netstat(1) 1810 only relies on KVM now for printing bandwidth upcall meters. 1811 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1812 ip6_mroute_mod respectively. The config(5) options for statically 1813 compiling this code remain the same, i.e. 'options MROUTING'. 1814 181520090315: 1816 Support for the IFF_NEEDSGIANT network interface flag has been 1817 removed, which means that non-MPSAFE network device drivers are no 1818 longer supported. In particular, if_ar, if_sr, and network device 1819 drivers from the old (legacy) USB stack can no longer be built or 1820 used. 1821 182220090313: 1823 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1824 a bunch of new language catalog files have also been added. 1825 This means that some common libc messages are now localized and 1826 they depend on the LC_MESSAGES environmental variable. 1827 182820090313: 1829 The k8temp(4) driver has been renamed to amdtemp(4) since 1830 support for Family 10 and Family 11 CPU families was added. 1831 183220090309: 1833 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1834 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1835 1836 For kernel developers, the most important changes are that the 1837 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1838 and this lock has been downgraded to a non-recursive mutex. 1839 1840 Transport protocols (UDP, Raw IP) are now responsible for filtering 1841 inbound multicast traffic according to group membership and source 1842 filters. The imo_multicast_filter() KPI exists for this purpose. 1843 Transports which do not use multicast (SCTP, TCP) already reject 1844 multicast by default. Forwarding and receive performance may improve 1845 as a mutex acquisition is no longer needed in the ip_input() 1846 low-level input path. in_addmulti() and in_delmulti() are shimmed 1847 to new KPIs which exist to support SSM in-kernel. 1848 1849 For application developers, it is recommended that loopback of 1850 multicast datagrams be disabled for best performance, as this 1851 will still cause the lock to be taken for each looped-back 1852 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1853 be tuned to 0 to disable loopback by default; it defaults to 1 1854 to preserve the existing behaviour. 1855 1856 For systems administrators, to obtain best performance with 1857 multicast reception and multiple groups, it is always recommended 1858 that a card with a suitably precise hash filter is used. Hash 1859 collisions will still result in the lock being taken within the 1860 transport protocol input path to check group membership. 1861 1862 If deploying FreeBSD in an environment with IGMP snooping switches, 1863 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1864 enabled; this forces 224.0.0.0/24 group membership to be announced 1865 via IGMP. 1866 1867 The size of 'struct igmpstat' has changed; netstat needs to be 1868 recompiled to reflect this. 1869 Bump __FreeBSD_version to 800070. 1870 187120090309: 1872 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1873 updated to use it. This requires a buildworld/installworld in order to 1874 update the library and dependencies (usbconfig, etc). Its advisable to 1875 rebuild all ports which uses libusb. More specific directions are given 1876 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1877 libusb are no longer required and can be removed. 1878 187920090302: 1880 A workaround is committed to allow the creation of System V shared 1881 memory segment of size > 2 GB on the 64-bit architectures. 1882 Due to a limitation of the existing ABI, the shm_segsz member 1883 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1884 wrong for large segments. Note that limits must be explicitly 1885 raised to allow such segments to be created. 1886 188720090301: 1888 The layout of struct ifnet has changed, requiring a rebuild of all 1889 network device driver modules. 1890 189120090227: 1892 The /dev handling for the new USB stack has changed, a 1893 buildworld/installworld is required for libusb20. 1894 189520090223: 1896 The new USB2 stack has now been permanently moved in and all kernel and 1897 module names reverted to their previous values (eg, usb, ehci, ohci, 1898 ums, ...). The old usb stack can be compiled in by prefixing the name 1899 with the letter 'o', the old usb modules have been removed. 1900 Updating entry 20090216 for xorg and 20090215 for libmap may still 1901 apply. 1902 190320090217: 1904 The rc.conf(5) option if_up_delay has been renamed to 1905 defaultroute_delay to better reflect its purpose. If you have 1906 customized this setting in /etc/rc.conf you need to update it to 1907 use the new name. 1908 190920090216: 1910 xorg 7.4 wants to configure its input devices via hald which does not 1911 yet work with USB2. If the keyboard/mouse does not work in xorg then 1912 add 1913 Option "AllowEmptyInput" "off" 1914 to your ServerLayout section. This will cause X to use the configured 1915 kbd and mouse sections from your xorg.conf. 1916 191720090215: 1918 The GENERIC kernels for all architectures now default to the new USB2 1919 stack. No kernel config options or code have been removed so if a 1920 problem arises please report it and optionally revert to the old USB 1921 stack. If you are loading USB kernel modules or have a custom kernel 1922 that includes GENERIC then ensure that usb names are also changed over, 1923 eg uftdi -> usb2_serial_ftdi. 1924 1925 Older programs linked against the ports libusb 0.1 need to be 1926 redirected to the new stack's libusb20. /etc/libmap.conf can 1927 be used for this: 1928 # Map old usb library to new one for usb2 stack 1929 libusb-0.1.so.8 libusb20.so.1 1930 193120090209: 1932 All USB ethernet devices now attach as interfaces under the name ueN 1933 (eg. ue0). This is to provide a predictable name as vendors often 1934 change usb chipsets in a product without notice. 1935 193620090203: 1937 The ichsmb(4) driver has been changed to require SMBus slave 1938 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1939 All of the other SMBus controller drivers require left-justified 1940 slave addresses, so this change makes all the drivers provide the 1941 same interface. 1942 194320090201: 1944 INET6 statistics (struct ip6stat) was updated. 1945 netstat(1) needs to be recompiled. 1946 194720090119: 1948 NTFS has been removed from GENERIC kernel on amd64 to match 1949 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1950 will load ntfs.ko module automatically when NTFS support is 1951 actually needed, unless ntfs.ko is not installed or security 1952 level prohibits loading kernel modules. If either is the case, 1953 "options NTFS" has to be added into kernel config. 1954 195520090115: 1956 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1957 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1958 800061. User space tools that rely on the size of struct tcpcb in 1959 tcp_var.h (e.g. sockstat) need to be recompiled. 1960 196120081225: 1962 ng_tty(4) module updated to match the new TTY subsystem. 1963 Due to API change, user-level applications must be updated. 1964 New API support added to mpd5 CVS and expected to be present 1965 in next mpd5.3 release. 1966 196720081219: 1968 With __FreeBSD_version 800060 the makefs tool is part of 1969 the base system (it was a port). 1970 197120081216: 1972 The afdata and ifnet locks have been changed from mutexes to 1973 rwlocks, network modules will need to be re-compiled. 1974 197520081214: 1976 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1977 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1978 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1979 architecture and 40 bytes on 64-bit architecture. The userland 1980 applications "arp" and "ndp" have been updated accordingly. 1981 The output from "netstat -r" shows only routing entries and 1982 none of the L2 information. 1983 198420081130: 1985 __FreeBSD_version 800057 marks the switchover from the 1986 binary ath hal to source code. Users must add the line: 1987 1988 options AH_SUPPORT_AR5416 1989 1990 to their kernel config files when specifying: 1991 1992 device ath_hal 1993 1994 The ath_hal module no longer exists; the code is now compiled 1995 together with the driver in the ath module. It is now 1996 possible to tailor chip support (i.e. reduce the set of chips 1997 and thereby the code size); consult ath_hal(4) for details. 1998 199920081121: 2000 __FreeBSD_version 800054 adds memory barriers to 2001 <machine/atomic.h>, new interfaces to ifnet to facilitate 2002 multiple hardware transmit queues for cards that support 2003 them, and a lock-less ring-buffer implementation to 2004 enable drivers to more efficiently manage queueing of 2005 packets. 2006 200720081117: 2008 A new version of ZFS (version 13) has been merged to -HEAD. 2009 This version has zpool attribute "listsnapshots" off by 2010 default, which means "zfs list" does not show snapshots, 2011 and is the same as Solaris behavior. 2012 201320081028: 2014 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 2015 201620081009: 2017 The uhci, ohci, ehci and slhci USB Host controller drivers have 2018 been put into separate modules. If you load the usb module 2019 separately through loader.conf you will need to load the 2020 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 2021 controller add the following to loader.conf: 2022 2023 uhci_load="YES" 2024 ehci_load="YES" 2025 202620081009: 2027 The ABI used by the PMC toolset has changed. Please keep 2028 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 2029 sync. 2030 203120081009: 2032 atapci kernel module now includes only generic PCI ATA 2033 driver. AHCI driver moved to ataahci kernel module. 2034 All vendor-specific code moved into separate kernel modules: 2035 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 2036 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 2037 atamarvell, atamicron, atanational, atanetcell, atanvidia, 2038 atapromise, ataserverworks, atasiliconimage, atasis, atavia 2039 204020080820: 2041 The TTY subsystem of the kernel has been replaced by a new 2042 implementation, which provides better scalability and an 2043 improved driver model. Most common drivers have been migrated to 2044 the new TTY subsystem, while others have not. The following 2045 drivers have not yet been ported to the new TTY layer: 2046 2047 PCI/ISA: 2048 cy, digi, rc, rp, sio 2049 2050 USB: 2051 ubser, ucycom 2052 2053 Line disciplines: 2054 ng_h4, ng_tty, ppp, sl, snp 2055 2056 Adding these drivers to your kernel configuration file shall 2057 cause compilation to fail. 2058 205920080818: 2060 ntpd has been upgraded to 4.2.4p5. 2061 206220080801: 2063 OpenSSH has been upgraded to 5.1p1. 2064 2065 For many years, FreeBSD's version of OpenSSH preferred DSA 2066 over RSA for host and user authentication keys. With this 2067 upgrade, we've switched to the vendor's default of RSA over 2068 DSA. This may cause upgraded clients to warn about unknown 2069 host keys even for previously known hosts. Users should 2070 follow the usual procedure for verifying host keys before 2071 accepting the RSA key. 2072 2073 This can be circumvented by setting the "HostKeyAlgorithms" 2074 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2075 command line. 2076 2077 Please note that the sequence of keys offered for 2078 authentication has been changed as well. You may want to 2079 specify IdentityFile in a different order to revert this 2080 behavior. 2081 208220080713: 2083 The sio(4) driver has been removed from the i386 and amd64 2084 kernel configuration files. This means uart(4) is now the 2085 default serial port driver on those platforms as well. 2086 2087 To prevent collisions with the sio(4) driver, the uart(4) driver 2088 uses different names for its device nodes. This means the 2089 onboard serial port will now most likely be called "ttyu0" 2090 instead of "ttyd0". You may need to reconfigure applications to 2091 use the new device names. 2092 2093 When using the serial port as a boot console, be sure to update 2094 /boot/device.hints and /etc/ttys before booting the new kernel. 2095 If you forget to do so, you can still manually specify the hints 2096 at the loader prompt: 2097 2098 set hint.uart.0.at="isa" 2099 set hint.uart.0.port="0x3F8" 2100 set hint.uart.0.flags="0x10" 2101 set hint.uart.0.irq="4" 2102 boot -s 2103 210420080609: 2105 The gpt(8) utility has been removed. Use gpart(8) to partition 2106 disks instead. 2107 210820080603: 2109 The version that Linuxulator emulates was changed from 2.4.2 2110 to 2.6.16. If you experience any problems with Linux binaries 2111 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2112 if it fixes the problem contact emulation mailing list. 2113 211420080525: 2115 ISDN4BSD (I4B) was removed from the src tree. You may need to 2116 update a your kernel configuration and remove relevant entries. 2117 211820080509: 2119 I have checked in code to support multiple routing tables. 2120 See the man pages setfib(1) and setfib(2). 2121 This is a hopefully backwards compatible version, 2122 but to make use of it you need to compile your kernel 2123 with options ROUTETABLES=2 (or more up to 16). 2124 212520080420: 2126 The 802.11 wireless support was redone to enable multi-bss 2127 operation on devices that are capable. The underlying device 2128 is no longer used directly but instead wlanX devices are 2129 cloned with ifconfig. This requires changes to rc.conf files. 2130 For example, change: 2131 ifconfig_ath0="WPA DHCP" 2132 to 2133 wlans_ath0=wlan0 2134 ifconfig_wlan0="WPA DHCP" 2135 see rc.conf(5) for more details. In addition, mergemaster of 2136 /etc/rc.d is highly recommended. Simultaneous update of userland 2137 and kernel wouldn't hurt either. 2138 2139 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2140 modules were merged into the base wlan module. All references 2141 to these modules (e.g. in kernel config files) must be removed. 2142 214320080408: 2144 psm(4) has gained write(2) support in native operation level. 2145 Arbitrary commands can be written to /dev/psm%d and status can 2146 be read back from it. Therefore, an application is responsible 2147 for status validation and error recovery. It is a no-op in 2148 other operation levels. 2149 215020080312: 2151 Support for KSE threading has been removed from the kernel. To 2152 run legacy applications linked against KSE libmap.conf may 2153 be used. The following libmap.conf may be used to ensure 2154 compatibility with any prior release: 2155 2156 libpthread.so.1 libthr.so.1 2157 libpthread.so.2 libthr.so.2 2158 libkse.so.3 libthr.so.3 2159 216020080301: 2161 The layout of struct vmspace has changed. This affects libkvm 2162 and any executables that link against libkvm and use the 2163 kvm_getprocs() function. In particular, but not exclusively, 2164 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2165 The effects are minimal, but it's advisable to upgrade world 2166 nonetheless. 2167 216820080229: 2169 The latest em driver no longer has support in it for the 2170 82575 adapter, this is now moved to the igb driver. The 2171 split was done to make new features that are incompatible 2172 with older hardware easier to do. 2173 217420080220: 2175 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2176 likewise the kernel option is now GEOM_LINUX_LVM. 2177 217820080211: 2179 The default NFS mount mode has changed from UDP to TCP for 2180 increased reliability. If you rely on (insecurely) NFS 2181 mounting across a firewall you may need to update your 2182 firewall rules. 2183 218420080208: 2185 Belatedly note the addition of m_collapse for compacting 2186 mbuf chains. 2187 218820080126: 2189 The fts(3) structures have been changed to use adequate 2190 integer types for their members and so to be able to cope 2191 with huge file trees. The old fts(3) ABI is preserved 2192 through symbol versioning in libc, so third-party binaries 2193 using fts(3) should still work, although they will not take 2194 advantage of the extended types. At the same time, some 2195 third-party software might fail to build after this change 2196 due to unportable assumptions made in its source code about 2197 fts(3) structure members. Such software should be fixed 2198 by its vendor or, in the worst case, in the ports tree. 2199 FreeBSD_version 800015 marks this change for the unlikely 2200 case that a portable fix is impossible. 2201 220220080123: 2203 To upgrade to -current after this date, you must be running 2204 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2205 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2206 220720071128: 2208 The ADAPTIVE_GIANT kernel option has been retired because its 2209 functionality is the default now. 2210 221120071118: 2212 The AT keyboard emulation of sunkbd(4) has been turned on 2213 by default. In order to make the special symbols of the Sun 2214 keyboards driven by sunkbd(4) work under X these now have 2215 to be configured the same way as Sun USB keyboards driven 2216 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2217 2218 Option "XkbLayout" "us" 2219 Option "XkbRules" "xorg" 2220 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2221 222220071024: 2223 It has been decided that it is desirable to provide ABI 2224 backwards compatibility to the FreeBSD 4/5/6 versions of the 2225 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2226 broken with the introduction of PCI domain support (see the 2227 20070930 entry). Unfortunately, this required the ABI of 2228 PCIOCGETCONF to be broken again in order to be able to 2229 provide backwards compatibility to the old version of that 2230 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2231 again. As for prominent ports this affects neither pciutils 2232 nor xorg-server this time, the hal port needs to be rebuilt 2233 however. 2234 223520071020: 2236 The misnamed kthread_create() and friends have been renamed 2237 to kproc_create() etc. Many of the callers already 2238 used kproc_start().. 2239 I will return kthread_create() and friends in a while 2240 with implementations that actually create threads, not procs. 2241 Renaming corresponds with version 800002. 2242 224320071010: 2244 RELENG_7 branched. 2245 2246COMMON ITEMS: 2247 2248 General Notes 2249 ------------- 2250 Avoid using make -j when upgrading. While generally safe, there are 2251 sometimes problems using -j to upgrade. If your upgrade fails with 2252 -j, please try again without -j. From time to time in the past there 2253 have been problems using -j with buildworld and/or installworld. This 2254 is especially true when upgrading between "distant" versions (eg one 2255 that cross a major release boundary or several minor releases, or when 2256 several months have passed on the -current branch). 2257 2258 Sometimes, obscure build problems are the result of environment 2259 poisoning. This can happen because the make utility reads its 2260 environment when searching for values for global variables. To run 2261 your build attempts in an "environmental clean room", prefix all make 2262 commands with 'env -i '. See the env(1) manual page for more details. 2263 2264 When upgrading from one major version to another it is generally best 2265 to upgrade to the latest code in the currently installed branch first, 2266 then do an upgrade to the new branch. This is the best-tested upgrade 2267 path, and has the highest probability of being successful. Please try 2268 this approach before reporting problems with a major version upgrade. 2269 2270 When upgrading a live system, having a root shell around before 2271 installing anything can help undo problems. Not having a root shell 2272 around can lead to problems if pam has changed too much from your 2273 starting point to allow continued authentication after the upgrade. 2274 2275 ZFS notes 2276 --------- 2277 When upgrading the boot ZFS pool to a new version, always follow 2278 these two steps: 2279 2280 1.) recompile and reinstall the ZFS boot loader and boot block 2281 (this is part of "make buildworld" and "make installworld") 2282 2283 2.) update the ZFS boot block on your boot drive 2284 2285 The following example updates the ZFS boot block on the first 2286 partition (freebsd-boot) of a GPT partitioned drive ad0: 2287 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2288 2289 Non-boot pools do not need these updates. 2290 2291 To build a kernel 2292 ----------------- 2293 If you are updating from a prior version of FreeBSD (even one just 2294 a few days old), you should follow this procedure. It is the most 2295 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2296 2297 make kernel-toolchain 2298 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2299 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2300 2301 To test a kernel once 2302 --------------------- 2303 If you just want to boot a kernel once (because you are not sure 2304 if it works, or if you want to boot a known bad kernel to provide 2305 debugging information) run 2306 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2307 nextboot -k testkernel 2308 2309 To just build a kernel when you know that it won't mess you up 2310 -------------------------------------------------------------- 2311 This assumes you are already running a CURRENT system. Replace 2312 ${arch} with the architecture of your machine (e.g. "i386", 2313 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2314 2315 cd src/sys/${arch}/conf 2316 config KERNEL_NAME_HERE 2317 cd ../compile/KERNEL_NAME_HERE 2318 make depend 2319 make 2320 make install 2321 2322 If this fails, go to the "To build a kernel" section. 2323 2324 To rebuild everything and install it on the current system. 2325 ----------------------------------------------------------- 2326 # Note: sometimes if you are running current you gotta do more than 2327 # is listed here if you are upgrading from a really old current. 2328 2329 <make sure you have good level 0 dumps> 2330 make buildworld 2331 make kernel KERNCONF=YOUR_KERNEL_HERE 2332 [1] 2333 <reboot in single user> [3] 2334 mergemaster -p [5] 2335 make installworld 2336 mergemaster -i [4] 2337 make delete-old [6] 2338 <reboot> 2339 2340 To cross-install current onto a separate partition 2341 -------------------------------------------------- 2342 # In this approach we use a separate partition to hold 2343 # current's root, 'usr', and 'var' directories. A partition 2344 # holding "/", "/usr" and "/var" should be about 2GB in 2345 # size. 2346 2347 <make sure you have good level 0 dumps> 2348 <boot into -stable> 2349 make buildworld 2350 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2351 <maybe newfs current's root partition> 2352 <mount current's root partition on directory ${CURRENT_ROOT}> 2353 make installworld DESTDIR=${CURRENT_ROOT} 2354 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2355 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2356 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2357 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2358 <reboot into current> 2359 <do a "native" rebuild/install as described in the previous section> 2360 <maybe install compatibility libraries from ports/misc/compat*> 2361 <reboot> 2362 2363 2364 To upgrade in-place from stable to current 2365 ---------------------------------------------- 2366 <make sure you have good level 0 dumps> 2367 make buildworld [9] 2368 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2369 [1] 2370 <reboot in single user> [3] 2371 mergemaster -p [5] 2372 make installworld 2373 mergemaster -i [4] 2374 make delete-old [6] 2375 <reboot> 2376 2377 Make sure that you've read the UPDATING file to understand the 2378 tweaks to various things you need. At this point in the life 2379 cycle of current, things change often and you are on your own 2380 to cope. The defaults can also change, so please read ALL of 2381 the UPDATING entries. 2382 2383 Also, if you are tracking -current, you must be subscribed to 2384 freebsd-current@freebsd.org. Make sure that before you update 2385 your sources that you have read and understood all the recent 2386 messages there. If in doubt, please track -stable which has 2387 much fewer pitfalls. 2388 2389 [1] If you have third party modules, such as vmware, you 2390 should disable them at this point so they don't crash your 2391 system on reboot. 2392 2393 [3] From the bootblocks, boot -s, and then do 2394 fsck -p 2395 mount -u / 2396 mount -a 2397 cd src 2398 adjkerntz -i # if CMOS is wall time 2399 Also, when doing a major release upgrade, it is required that 2400 you boot into single user mode to do the installworld. 2401 2402 [4] Note: This step is non-optional. Failure to do this step 2403 can result in a significant reduction in the functionality of the 2404 system. Attempting to do it by hand is not recommended and those 2405 that pursue this avenue should read this file carefully, as well 2406 as the archives of freebsd-current and freebsd-hackers mailing lists 2407 for potential gotchas. The -U option is also useful to consider. 2408 See mergemaster(8) for more information. 2409 2410 [5] Usually this step is a noop. However, from time to time 2411 you may need to do this if you get unknown user in the following 2412 step. It never hurts to do it all the time. You may need to 2413 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2414 install) after the buildworld before this step if you last updated 2415 from current before 20130425 or from -stable before 20130430. 2416 2417 [6] This only deletes old files and directories. Old libraries 2418 can be deleted by "make delete-old-libs", but you have to make 2419 sure that no program is using those libraries anymore. 2420 2421 [8] In order to have a kernel that can run the 4.x binaries needed to 2422 do an installworld, you must include the COMPAT_FREEBSD4 option in 2423 your kernel. Failure to do so may leave you with a system that is 2424 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2425 required to run the 5.x binaries on more recent kernels. And so on 2426 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2427 2428 Make sure that you merge any new devices from GENERIC since the 2429 last time you updated your kernel config file. 2430 2431 [9] When checking out sources, you must include the -P flag to have 2432 cvs prune empty directories. 2433 2434 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2435 "?=" instead of the "=" assignment operator, so that buildworld can 2436 override the CPUTYPE if it needs to. 2437 2438 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2439 not on the command line, or in /etc/make.conf. buildworld will 2440 warn if it is improperly defined. 2441FORMAT: 2442 2443This file contains a list, in reverse chronological order, of major 2444breakages in tracking -current. It is not guaranteed to be a complete 2445list of such breakages, and only contains entries since October 10, 2007. 2446If you need to see UPDATING entries from before that date, you will need 2447to fetch an UPDATING file from an older FreeBSD release. 2448 2449Copyright information: 2450 2451Copyright 1998-2009 M.
