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 1920180308 p28 FreeBSD-SA-18:01.ipsec [revised] 20 21 Fix ipsec validation and use-after-free. 22 2320180307 p27 FreeBSD-SA-18:01.ipsec 24 FreeBSD-SA-18:02.ntp 25 FreeBSD-EN-18:01.tzdata 26 FreeBSD-EN-18:02.file 27 28 Fix ipsec validation and use-after-free.

They are 209 still available in the security/openssh-portable port. 210 21120151214: 212 r292223 changed the internal interface between the nfsd.ko and 213 nfscommon.ko modules. As such, they must both be upgraded to-gether. 214 __FreeBSD_version has been bumped because of this. 215 21620151113: 217 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 218 Kernel modules isp_2400_multi and isp_2500_multi were removed and 219 should be replaced with isp_2400 and isp_2500 modules respectively. 220 22120150806: 222 The menu.rc and loader.rc files will now be replaced during 223 upgrades. Please migrate local changes to menu.rc.local and 224 loader.rc.local instead. 225 22620151026: 227 NTP has been upgraded to 4.2.8p4. 228 22920151025: 230 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 231 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 232 and devel/kyua to version 0.20+ and adjust any calling code to work 233 with Kyuafile and kyua. 234 23520150823: 236 The polarity of Pulse Per Second (PPS) capture events with the 237 uart(4) driver has been corrected. Prior to this change the PPS 238 "assert" event corresponded to the trailing edge of a positive PPS 239 pulse and the "clear" event was the leading edge of the next pulse. 240 241 As the width of a PPS pulse in a typical GPS receiver is on the 242 order of 1 millisecond, most users will not notice any significant 243 difference with this change. 244 245 Anyone who has compensated for the historical polarity reversal by 246 configuring a negative offset equal to the pulse width will need to 247 remove that workaround. 248 24920150822: 250 From legacy ata(4) driver was removed support for SATA controllers 251 supported by more functional drivers ahci(4), siis(4) and mvs(4). 252 Kernel modules ataahci and ataadaptec were removed completely, 253 replaced by ahci and mvs modules respectively. 254 25520150813: 256 10.2-RELEASE. 257 25820150731: 259 As ZFS requires more kernel stack pages than is the default on some 260 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 261 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 262 263 Please consider using 'options KSTACK_PAGES=X' where X is greater 264 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 265 26620150703: 267 The default Unbound configuration now enables remote control 268 using a local socket. Users who have already enabled the 269 local_unbound service should regenerate their configuration 270 by running "service local_unbound setup" as root. 271 27220150624: 273 An additional fix for the issue described in the 20150614 sendmail 274 entry below has been been committed in revision 284786. 275 27620150615: 277 The fix for the issue described in the 20150614 sendmail entry 278 below has been been committed in revision 284485. The work 279 around described in that entry is no longer needed unless the 280 default setting is overridden by a confDH_PARAMETERS configuration 281 setting of '5' or pointing to a 512 bit DH parameter file. 282 28320150614: 284 The import of openssl to address the FreeBSD-SA-15:10.openssl 285 security advisory includes a change which rejects handshakes 286 with DH parameters below 768 bits. sendmail releases prior 287 to 8.15.2 (not yet released), defaulted to a 512 bit 288 DH parameter setting for client connections. To work around 289 this interoperability, sendmail can be configured to use a 290 2048 bit DH parameter by: 291 292 1. Edit /etc/mail/`hostname`.mc 293 2. If a setting for confDH_PARAMETERS does not exist or 294 exists and is set to a string beginning with '5', 295 replace it with '2'. 296 3. If a setting for confDH_PARAMETERS exists and is set to 297 a file path, create a new file with: 298 openssl dhparam -out /path/to/file 2048 299 4. Rebuild the .cf file: 300 cd /etc/mail/; make; make install 301 5. Restart sendmail: 302 cd /etc/mail/; make restart 303 304 A sendmail patch is coming, at which time this file will be 305 updated. 306 30720150601: 308 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 309 defined in symlink(7); previously symlinks were silently ignored. 310 31120150430: 312 The const qualifier has been removed from iconv(3) to comply with 313 POSIX. The ports tree is aware of this from r384038 onwards. 314 31520141215: 316 At svn r275807, The default linux compat kernel ABI has been adjusted 317 to 2.6.18 in support of the linux-c6 compat ports infrastructure 318 update. If you wish to continue using the linux-f10 compat ports, 319 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 320 encouraged to update their linux-compat packages to linux-c6 during 321 their next update cycle. 322 323 See ports/UPDATING 20141209 and 20141215 on migration to CentOS 6 ports. 324 32520141205: 326 pjdfstest has been integrated into kyua as an opt-in test suite. 327 Please see share/doc/pjdfstest/README for a more details on how to 328 execute it. 329 33020141118: 331 10.1-RELEASE. 332 33320140904: 334 The ofwfb driver, used to provide a graphics console on PowerPC when 335 using vt(4), no longer allows mmap() of all of physical memory. This 336 will prevent Xorg on PowerPC with some ATI graphics cards from 337 initializing properly unless x11-servers/xorg-server is updated to 338 1.12.4_8 or newer. 339 34020140831: 341 The libatf-c and libatf-c++ major versions were downgraded to 0 and 342 1 respectively to match the upstream numbers. They were out of 343 sync because, when they were originally added to FreeBSD, the 344 upstream versions were not respected. These libraries are private 345 and not yet built by default, so renumbering them should be a 346 non-issue. However, unclean source trees will yield broken test 347 programs once the operator executes "make delete-old-libs" after a 348 "make installworld". 349 350 Additionally, the atf-sh binary was made private by moving it into 351 /usr/libexec/. Already-built shell test programs will keep the 352 path to the old binary so they will break after "make delete-old" 353 is run. 354 355 If you are using WITH_TESTS=yes (not the default), wipe the object 356 tree and rebuild from scratch to prevent spurious test failures. 357 This is only needed once: the misnumbered libraries and misplaced 358 binaries have been added to OptionalObsoleteFiles.inc so they will 359 be removed during a clean upgrade. 360 36120140814: 362 The ixgbe tunables now match their sysctl counterparts, for example: 363 hw.ixgbe.enable_aim => hw.ix.enable_aim 364 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 365 36620140801: 367 The NFSv4.1 server committed by r269398 changes the internal 368 function call interfaces used between the NFS and krpc modules. 369 As such, __FreeBSD_version was bumped. 370 37120140729: 372 The default unbound configuration has been modified to address 373 issues with reverse lookups on networks that use private 374 address ranges. If you use the local_unbound service, run 375 "service local_unbound setup" as root to regenerate your 376 configuration, then "service local_unbound reload" to load the 377 new configuration. 378 37920140717: 380 It is no longer necessary to include the dwarf version in your DEBUG 381 options in your kernel config file. The bug that required it to be 382 placed in the config file has bene fixed. DEBUG should now just 383 contain -g. The build system will automatically update things 384 to do the right thing. 385 38620140715: 387 Several ABI breaking changes were merged to CTL and new iSCSI code. 388 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 389 iscsictl need to be rebuilt to work with a new kernel. 390 39120140708: 392 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 393 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 394 which differs from the behaviour controlled by this knob.) 395 39620140608: 397 On i386 and amd64 systems, the onifconsole flag is now set by default 398 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 399 as a login TTY if it is set in the bootloader as an active kernel 400 console. No changes in behavior should result otherwise. To revert to 401 the previous behavior, set ttyu0 to "off" in /etc/ttys. 402 40320140512: 404 Clang and llvm have been upgraded to 3.4.1 release. 405 40620140321: 407 Clang and llvm have been upgraded to 3.4 release. 408 40920140306: 410 If a Makefile in a tests/ directory was auto-generating a Kyuafile 411 instead of providing an explicit one, this would prevent such 412 Makefile from providing its own Kyuafile in the future during 413 NO_CLEAN builds. This has been fixed in the Makefiles but manual 414 intervention is needed to clean an objdir if you use NO_CLEAN: 415 # find /usr/obj -name Kyuafile | xargs rm -f 416 41720140303: 418 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 419 capability mode support. Please note that enabling the feature in 420 kernel is still highly recommended. 421 42220140227: 423 OpenSSH is now built with sandbox support, and will use sandbox as 424 the default privilege separation method. This requires Capsicum 425 capability mode support in kernel. 426 42720140216: 428 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 429 been deprecated and will not be part of FreeBSD 11.0 and later 430 releases. If you use this driver, please consider switching to 431 the nfe(4) driver instead. 432 43320140120: 434 10.0-RELEASE. 435 43620131216: 437 The behavior of gss_pseudo_random() for the krb5 mechanism 438 has changed, for applications requesting a longer random string 439 than produced by the underlying enctype's pseudo-random() function. 440 In particular, the random string produced from a session key of 441 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 442 be different at the 17th octet and later, after this change. 443 The counter used in the PRF+ construction is now encoded as a 444 big-endian integer in accordance with RFC 4402. 445 __FreeBSD_version is bumped to 1000701. 446 44720131108: 448 The WITHOUT_ATF build knob has been removed and its functionality 449 has been subsumed into the more generic WITHOUT_TESTS. If you were 450 using the former to disable the build of the ATF libraries, you 451 should change your settings to use the latter. 452 45320131031: 454 The default version of mtree is nmtree which is obtained from 455 NetBSD. The output is generally the same, but may vary 456 slightly. If you found you need identical output adding 457 "-F freebsd9" to the command line should do the trick. For the 458 time being, the old mtree is available as fmtree. 459 46020131014: 461 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 462 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 463 1.1.4_8 and verify bsdyml not linked in, before running "make 464 delete-old-libs": 465 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 466 or 467 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 468 46920131010: 470 The rc.d/jail script has been updated to support jail(8) 471 configuration file. The "jail_<jname>_*" rc.conf(5) variables 472 for per-jail configuration are automatically converted to 473 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 474 This is transparently backward compatible. See below about some 475 incompatibilities and rc.conf(5) manual page for more details. 476 477 These variables are now deprecated in favor of jail(8) configuration 478 file. One can use "rc.d/jail config <jname>" command to generate 479 a jail(8) configuration file in /var/run/jail.<jname>.conf without 480 running the jail(8) utility. The default pathname of the 481 configuration file is /etc/jail.conf and can be specified by 482 using $jail_conf or $jail_<jname>_conf variables. 483 484 Please note that jail_devfs_ruleset accepts an integer at 485 this moment. Please consider to rewrite the ruleset name 486 with an integer. 487 48820130930: 489 BIND has been removed from the base system. If all you need 490 is a local resolver, simply enable and start the local_unbound 491 service instead. Otherwise, several versions of BIND are 492 available in the ports tree. The dns/bind99 port is one example. 493 494 With this change, nslookup(1) and dig(1) are no longer in the base 495 system. Users should instead use host(1) and drill(1) which are 496 in the base system. Alternatively, nslookup and dig can 497 be obtained by installing the dns/bind-tools port. 498 49920130916: 500 With the addition of unbound(8), a new unbound user is now 501 required during installworld. "mergemaster -p" can be used to 502 add the user prior to installworld, as documented in the handbook. 503 50420130911: 505 OpenSSH is now built with DNSSEC support, and will by default 506 silently trust signed SSHFP records. This can be controlled with 507 the VerifyHostKeyDNS client configuration setting. DNSSEC support 508 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 509 51020130906: 511 The GNU Compiler Collection and C++ standard library (libstdc++) 512 are no longer built by default on platforms where clang is the system 513 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 514 options in src.conf. 515 51620130905: 517 The PROCDESC kernel option is now part of the GENERIC kernel 518 configuration and is required for the rwhod(8) to work. 519 If you are using custom kernel configuration, you should include 520 'options PROCDESC'. 521 52220130905: 523 The API and ABI related to the Capsicum framework was modified 524 in backward incompatible way. The userland libraries and programs 525 have to be recompiled to work with the new kernel. This includes the 526 following libraries and programs, but the whole buildworld is 527 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 528 kdump, procstat, rwho, rwhod, uniq. 529 53020130903: 531 AES-NI intrinsic support has been added to gcc. The AES-NI module 532 has been updated to use this support. A new gcc is required to build 533 the aesni module on both i386 and amd64. 534 53520130821: 536 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 537 Thus "device padlock_rng" and "device rdrand_rng" should be 538 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 539 54020130813: 541 WITH_ICONV has been split into two feature sets. WITH_ICONV now 542 enables just the iconv* functionality and is now on by default. 543 WITH_LIBICONV_COMPAT enables the libiconv api and link time 544 compatability. Set WITHOUT_ICONV to build the old way. 545 If you have been using WITH_ICONV before, you will very likely 546 need to turn on WITH_LIBICONV_COMPAT. 547 54820130806: 549 INVARIANTS option now enables DEBUG for code with OpenSolaris and 550 Illumos origin, including ZFS. If you have INVARIANTS in your 551 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 552 explicitly. 553 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 554 locks if WITNESS option was set. Because that generated a lot of 555 witness(9) reports and all of them were believed to be false 556 positives, this is no longer done. New option OPENSOLARIS_WITNESS 557 can be used to achieve the previous behavior. 558 55920130806: 560 Timer values in IPv6 data structures now use time_uptime instead 561 of time_second. Although this is not a user-visible functional 562 change, userland utilities which directly use them---ndp(8), 563 rtadvd(8), and rtsold(8) in the base system---need to be updated 564 to r253970 or later. 565 56620130802: 567 find -delete can now delete the pathnames given as arguments, 568 instead of only files found below them or if the pathname did 569 not contain any slashes. Formerly, the following error message 570 would result: 571 572 find: -delete: <path>: relative path potentially not safe 573 574 Deleting the pathnames given as arguments can be prevented 575 without error messages using -mindepth 1 or by changing 576 directory and passing "." as argument to find. This works in the 577 old as well as the new version of find. 578 57920130726: 580 Behavior of devfs rules path matching has been changed. 581 Pattern is now always matched against fully qualified devfs 582 path and slash characters must be explicitly matched by 583 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 584 subdirectories must be reviewed. 585 58620130716: 587 The default ARM ABI has changed to the ARM EABI. The old ABI is 588 incompatible with the ARM EABI and all programs and modules will 589 need to be rebuilt to work with a new kernel. 590 591 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 592 593 NOTE: Support for the old ABI will be removed in the future and 594 users are advised to upgrade. 595 59620130709: 597 pkg_install has been disconnected from the build if you really need it 598 you should add WITH_PKGTOOLS in your src.conf(5). 599 60020130709: 601 Most of network statistics structures were changed to be able 602 keep 64-bits counters. Thus all tools, that work with networking 603 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 604 60520130618: 606 Fix a bug that allowed a tracing process (e.g. gdb) to write 607 to a memory-mapped file in the traced process's address space 608 even if neither the traced process nor the tracing process had 609 write access to that file. 610 61120130615: 612 CVS has been removed from the base system. An exact copy 613 of the code is available from the devel/cvs port. 614 61520130613: 616 Some people report the following error after the switch to bmake: 617 618 make: illegal option -- J 619 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 620 ... 621 *** [buildworld] Error code 2 622 623 this likely due to an old instance of make in 624 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 625 which src/Makefile will use that blindly, if it exists, so if 626 you see the above error: 627 628 rm -rf `make -V MAKEPATH` 629 630 should resolve it. 631 63220130516: 633 Use bmake by default. 634 Whereas before one could choose to build with bmake via 635 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 636 make. The goal is to remove these knobs for 10-RELEASE. 637 638 It is worth noting that bmake (like gmake) treats the command 639 line as the unit of failure, rather than statements within the 640 command line. Thus '(cd some/where && dosomething)' is safer 641 than 'cd some/where; dosomething'. The '()' allows consistent 642 behavior in parallel build. 643 64420130429: 645 Fix a bug that allows NFS clients to issue READDIR on files. 646 64720130426: 648 The WITHOUT_IDEA option has been removed because 649 the IDEA patent expired. 650 65120130426: 652 The sysctl which controls TRIM support under ZFS has been renamed 653 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 654 enabled by default. 655 65620130425: 657 The mergemaster command now uses the default MAKEOBJDIRPREFIX 658 rather than creating it's own in the temporary directory in 659 order allow access to bootstrapped versions of tools such as 660 install and mtree. When upgrading from version of FreeBSD where 661 the install command does not support -l, you will need to 662 install a new mergemaster command if mergemaster -p is required. 663 This can be accomplished with the command (cd src/usr.sbin/mergemaster 664 && make install). 665 66620130404: 667 Legacy ATA stack, disabled and replaced by new CAM-based one since 668 FreeBSD 9.0, completely removed from the sources. Kernel modules 669 atadisk and atapi*, user-level tools atacontrol and burncd are 670 removed. Kernel option `options ATA_CAM` is now permanently enabled 671 and removed. 672 67320130319: 674 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 675 and socketpair(2). Software, in particular Kerberos, may 676 automatically detect and use these during building. The resulting 677 binaries will not work on older kernels. 678 67920130308: 680 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 681 information, see the respective 20130304 entry). 682 68320130304: 684 Recent commits to callout(9) changed the size of struct callout, 685 so the KBI is probably heavily disturbed. Also, some functions 686 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 687 by macros. Every kernel module using it won't load, so rebuild 688 is requested. 689 690 The ctl device has been re-enabled in GENERIC for i386 and amd64, 691 but does not initialize by default (because of the new CTL_DISABLE 692 option) to save memory. To re-enable it, remove the CTL_DISABLE 693 option from the kernel config file or set kern.cam.ctl.disable=0 694 in /boot/loader.conf. 695 69620130301: 697 The ctl device has been disabled in GENERIC for i386 and amd64. 698 This was done due to the extra memory being allocated at system 699 initialisation time by the ctl driver which was only used if 700 a CAM target device was created. This makes a FreeBSD system 701 unusable on 128MB or less of RAM. 702 70320130208: 704 A new compression method (lz4) has been merged to -HEAD. Please 705 refer to zpool-features(7) for more information. 706 707 Please refer to the "ZFS notes" section of this file for information 708 on upgrading boot ZFS pools. 709 71020130129: 711 A BSD-licensed patch(1) variant has been added and is installed 712 as bsdpatch, being the GNU version the default patch. 713 To inverse the logic and use the BSD-licensed one as default, 714 while having the GNU version installed as gnupatch, rebuild 715 and install world with the WITH_BSD_PATCH knob set. 716 71720130121: 718 Due to the use of the new -l option to install(1) during build 719 and install, you must take care not to directly set the INSTALL 720 make variable in your /etc/make.conf, /etc/src.conf, or on the 721 command line. If you wish to use the -C flag for all installs 722 you may be able to add INSTALL+=-C to /etc/make.conf or 723 /etc/src.conf. 724 72520130118: 726 The install(1) option -M has changed meaning and now takes an 727 argument that is a file or path to append logs to. In the 728 unlikely event that -M was the last option on the command line 729 and the command line contained at least two files and a target 730 directory the first file will have logs appended to it. The -M 731 option served little practical purpose in the last decade so its 732 use is expected to be extremely rare. 733 73420121223: 735 After switching to Clang as the default compiler some users of ZFS 736 on i386 systems started to experience stack overflow kernel panics. 737 Please consider using 'options KSTACK_PAGES=4' in such configurations. 738 73920121222: 740 GEOM_LABEL now mangles label names read from file system metadata. 741 Mangling affect labels containing spaces, non-printable characters, 742 '%' or '"'. Device names in /etc/fstab and other places may need to 743 be updated. 744 74520121217: 746 By default, only the 10 most recent kernel dumps will be saved. To 747 restore the previous behaviour (no limit on the number of kernel dumps 748 stored in the dump directory) add the following line to /etc/rc.conf: 749 750 savecore_flags="" 751 75220121201: 753 With the addition of auditdistd(8), a new auditdistd user is now 754 required during installworld. "mergemaster -p" can be used to 755 add the user prior to installworld, as documented in the handbook. 756 75720121117: 758 The sin6_scope_id member variable in struct sockaddr_in6 is now 759 filled by the kernel before passing the structure to the userland via 760 sysctl or routing socket. This means the KAME-specific embedded scope 761 id in sin6_addr.s6_addr[2] is always cleared in userland application. 762 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 763 __FreeBSD_version is bumped to 1000025. 764 76520121105: 766 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 767 This means that the world and kernel will be compiled with clang 768 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 769 and /usr/bin/cpp. To disable this behavior and revert to building 770 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 771 of current may need to bootstrap WITHOUT_CLANG first if the clang 772 build fails (its compatibility window doesn't extend to the 9 stable 773 branch point). 774 77520121102: 776 The IPFIREWALL_FORWARD kernel option has been removed. Its 777 functionality now turned on by default. 778 77920121023: 780 The ZERO_COPY_SOCKET kernel option has been removed and 781 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 782 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 783 mechanism which is not safe and may result in kernel crashes. 784 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 785 driver supports disposeable external page sized mbuf storage. 786 Proper replacements for both zero-copy mechanisms are under 787 consideration and will eventually lead to complete removal 788 of the two kernel options. 789 79020121023: 791 The IPv4 network stack has been converted to network byte 792 order. The following modules need to be recompiled together 793 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 794 pf(4), ipfw(4), ng_ipfw(4), stf(4). 795 79620121022: 797 Support for non-MPSAFE filesystems was removed from VFS. The 798 VFS_VERSION was bumped, all filesystem modules shall be 799 recompiled. 800 80120121018: 802 All the non-MPSAFE filesystems have been disconnected from 803 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 804 portalfs, smbfs, xfs. 805 80620121016: 807 The interface cloning API and ABI has changed. The following 808 modules need to be recompiled together with kernel: 809 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 810 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 811 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 812 81320121015: 814 The sdhci driver was split in two parts: sdhci (generic SD Host 815 Controller logic) and sdhci_pci (actual hardware driver). 816 No kernel config modifications are required, but if you 817 load sdhc as a module you must switch to sdhci_pci instead. 818 81920121014: 820 Import the FUSE kernel and userland support into base system. 821 82220121013: 823 The GNU sort(1) program has been removed since the BSD-licensed 824 sort(1) has been the default for quite some time and no serious 825 problems have been reported. The corresponding WITH_GNU_SORT 826 knob has also gone. 827 82820121006: 829 The pfil(9) API/ABI for AF_INET family has been changed. Packet 830 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 831 with new kernel. 832 83320121001: 834 The net80211(4) ABI has been changed to allow for improved driver 835 PS-POLL and power-save support. All wireless drivers need to be 836 recompiled to work with the new kernel. 837 83820120913: 839 The random(4) support for the VIA hardware random number 840 generator (`PADLOCK') is no longer enabled unconditionally. 841 Add the padlock_rng device in the custom kernel config if 842 needed. The GENERIC kernels on i386 and amd64 do include the 843 device, so the change only affects the custom kernel 844 configurations. 845 84620120908: 847 The pf(4) packet filter ABI has been changed. pfctl(8) and 848 snmp_pf module need to be recompiled to work with new kernel. 849 85020120828: 851 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 852 to -HEAD. Pools that have empty_bpobj in active state can not be 853 imported read-write with ZFS implementations that do not support 854 this feature. For more information read the zpool-features(5) 855 manual page. 856 85720120727: 858 The sparc64 ZFS loader has been changed to no longer try to auto- 859 detect ZFS providers based on diskN aliases but now requires these 860 to be explicitly listed in the OFW boot-device environment variable. 861 86220120712: 863 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 864 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 865 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 866 86720120712: 868 The following sysctls and tunables have been renamed for consistency 869 with other variables: 870 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 871 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 872 87320120628: 874 The sort utility has been replaced with BSD sort. For now, GNU sort 875 is also available as "gnusort" or the default can be set back to 876 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 877 installed as "bsdsort". 878 87920120611: 880 A new version of ZFS (pool version 5000) has been merged to -HEAD. 881 Starting with this version the old system of ZFS pool versioning 882 is superseded by "feature flags". This concept enables forward 883 compatibility against certain future changes in functionality of ZFS 884 pools. The first read-only compatible "feature flag" for ZFS pools 885 is named "com.delphix:async_destroy". For more information 886 read the new zpool-features(5) manual page. 887 Please refer to the "ZFS notes" section of this file for information 888 on upgrading boot ZFS pools. 889 89020120417: 891 The malloc(3) implementation embedded in libc now uses sources imported 892 as contrib/jemalloc. The most disruptive API change is to 893 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 894 delete it prior to installworld, and optionally re-create it using the 895 new format after rebooting. See malloc.conf(5) for details 896 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 897 NAMESPACE section). 898 89920120328: 900 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 901 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 902 now spelled mips. This is to aid compatibility with third-party 903 software that expects this naming scheme in uname(3). Little-endian 904 settings are unchanged. If you are updating a big-endian mips64 machine 905 from before this change, you may need to set MACHINE_ARCH=mips64 in 906 your environment before the new build system will recognize your machine. 907 90820120306: 909 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 910 platforms. 911 91220120229: 913 Now unix domain sockets behave "as expected" on nullfs(5). Previously 914 nullfs(5) did not pass through all behaviours to the underlying layer, 915 as a result if we bound to a socket on the lower layer we could connect 916 only to the lower path; if we bound to the upper layer we could connect 917 only to the upper path. The new behavior is one can connect to both the 918 lower and the upper paths regardless what layer path one binds to. 919 92020120211: 921 The getifaddrs upgrade path broken with 20111215 has been restored. 922 If you have upgraded in between 20111215 and 20120209 you need to 923 recompile libc again with your kernel. You still need to recompile 924 world to be able to configure CARP but this restriction already 925 comes from 20111215. 926 92720120114: 928 The set_rcvar() function has been removed from /etc/rc.subr. All 929 base and ports rc.d scripts have been updated, so if you have a 930 port installed with a script in /usr/local/etc/rc.d you can either 931 hand-edit the rcvar= line, or reinstall the port. 932 933 An easy way to handle the mass-update of /etc/rc.d: 934 rm /etc/rc.d/* && mergemaster -i 935 93620120109: 937 panic(9) now stops other CPUs in the SMP systems, disables interrupts 938 on the current CPU and prevents other threads from running. 939 This behavior can be reverted using the kern.stop_scheduler_on_panic 940 tunable/sysctl. 941 The new behavior can be incompatible with kern.sync_on_panic. 942 94320111215: 944 The carp(4) facility has been changed significantly. Configuration 945 of the CARP protocol via ifconfig(8) has changed, as well as format 946 of CARP events submitted to devd(8) has changed. See manual pages 947 for more information. The arpbalance feature of carp(4) is currently 948 not supported anymore. 949 950 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 951 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 952 need to be recompiled. 953 95420111122: 955 The acpi_wmi(4) status device /dev/wmistat has been renamed to 956 /dev/wmistat0. 957 95820111108: 959 The option VFS_ALLOW_NONMPSAFE option has been added in order to 960 explicitely support non-MPSAFE filesystems. 961 It is on by default for all supported platform at this present 962 time. 963 96420111101: 965 The broken amd(4) driver has been replaced with esp(4) in the amd64, 966 i386 and pc98 GENERIC kernel configuration files. 967 96820110930: 969 sysinstall has been removed 970 97120110923: 972 The stable/9 branch created in subversion. This corresponds to the 973 RELENG_9 branch in CVS. 974 97520110913: 976 This commit modifies vfs_register() so that it uses a hash 977 calculation to set vfc_typenum, which is enabled by default. 978 The first time a system is booted after this change, the 979 vfc_typenum values will change for all file systems. The 980 main effect of this is a change to the NFS server file handles 981 for file systems that use vfc_typenum in their fsid, such as ZFS. 982 It will, however, prevent vfc_typenum from changing when file 983 systems are loaded in a different order for subsequent reboots. 984 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 985 until you are ready to remount all NFS clients after a reboot. 986 98720110828: 988 Bump the shared library version numbers for libraries that 989 do not use symbol versioning, have changed the ABI compared 990 to stable/8 and which shared library version was not bumped. 991 Done as part of 9.0-RELEASE cycle. 992 99320110815: 994 During the merge of Capsicum features, the fget(9) KPI was modified. 995 This may require the rebuilding of out-of-tree device drivers -- 996 issues have been reported specifically with the nVidia device driver. 997 __FreeBSD_version is bumped to 900041. 998 999 Also, there is a period between 20110811 and 20110814 where the 1000 special devices /dev/{stdin,stdout,stderr} did not work correctly. 1001 Building world from a kernel during that window may not work. 1002 100320110628: 1004 The packet filter (pf) code has been updated to OpenBSD 4.5. 1005 You need to update userland tools to be in sync with kernel. 1006 This update breaks backward compatibility with earlier pfsync(4) 1007 versions. Care must be taken when updating redundant firewall setups. 1008 100920110608: 1010 The following sysctls and tunables are retired on x86 platforms: 1011 machdep.hlt_cpus 1012 machdep.hlt_logical_cpus 1013 The following sysctl is retired: 1014 machdep.hyperthreading_allowed 1015 The sysctls were supposed to provide a way to dynamically offline and 1016 online selected CPUs on x86 platforms, but the implementation has not 1017 been reliable especially with SCHED_ULE scheduler. 1018 machdep.hyperthreading_allowed tunable is still available to ignore 1019 hyperthreading CPUs at OS level. 1020 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 1021 where X is an APIC ID of a CPU. Be advised, though, that disabling 1022 CPUs in non-uniform fashion will result in non-uniform topology and 1023 may lead to sub-optimal system performance with SCHED_ULE, which is 1024 a default scheduler. 1025 102620110607: 1027 cpumask_t type is retired and cpuset_t is used in order to describe 1028 a mask of CPUs. 1029 103020110531: 1031 Changes to ifconfig(8) for dynamic address family detection mandate 1032 that you are running a kernel of 20110525 or later. Make sure to 1033 follow the update procedure to boot a new kernel before installing 1034 world. 1035 103620110513: 1037 Support for sun4v architecture is officially dropped 1038 103920110503: 1040 Several KPI breaking changes have been committed to the mii(4) layer, 1041 the PHY drivers and consequently some Ethernet drivers using mii(4). 1042 This means that miibus.ko and the modules of the affected Ethernet 1043 drivers need to be recompiled. 1044 1045 Note to kernel developers: Given that the OUI bit reversion problem 1046 was fixed as part of these changes all mii(4) commits related to OUIs, 1047 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 1048 handling, no longer can be merged verbatim to stable/8 and previous 1049 branches. 1050 105120110430: 1052 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 1053 into their kernel configurations along with 'device pci'. 1054 105520110427: 1056 The default NFS client is now the new NFS client, so fstype "newnfs" 1057 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 1058 Although mounts via fstype "nfs" will usually work without userland 1059 changes, it is recommended that the mount(8) and mount_nfs(8) 1060 commands be rebuilt from sources and that a link to mount_nfs called 1061 mount_oldnfs be created. The new client is compiled into the 1062 kernel with "options NFSCL" and this is needed for diskless root 1063 file systems. The GENERIC kernel configs have been changed to use 1064 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1065 To use the regular/old client, you can "mount -t oldnfs ...". For 1066 a diskless root file system, you must also include a line like: 1067 1068 vfs.root.mountfrom="oldnfs:" 1069 1070 in the boot/loader.conf on the root fs on the NFS server to make 1071 a diskless root fs use the old client. 1072 107320110424: 1074 The GENERIC kernels for all architectures now default to the new 1075 CAM-based ATA stack. It means that all legacy ATA drivers were 1076 removed and replaced by respective CAM drivers. If you are using 1077 ATA device names in /etc/fstab or other places, make sure to update 1078 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 1079 where 'Y's are the sequential numbers starting from zero for each type 1080 in order of detection, unless configured otherwise with tunables, 1081 see cam(4)). There will be symbolic links created in /dev/ to map 1082 old adX devices to the respective adaY. They should provide basic 1083 compatibility for file systems mounting in most cases, but they do 1084 not support old user-level APIs and do not have respective providers 1085 in GEOM. Consider using updated management tools with new device names. 1086 1087 It is possible to load devices ahci, ata, siis and mvs as modules, 1088 but option ATA_CAM should remain in kernel configuration to make ata 1089 module work as CAM driver supporting legacy ATA controllers. Device ata 1090 still can be used in modular fashion (atacore + ...). Modules atadisk 1091 and atapi* are not used and won't affect operation in ATA_CAM mode. 1092 Note that to use CAM-based ATA kernel should include CAM devices 1093 scbus, pass, da (or explicitly ada), cd and optionally others. All of 1094 them are parts of the cam module. 1095 1096 ataraid(4) functionality is now supported by the RAID GEOM class. 1097 To use it you can load geom_raid kernel module and use graid(8) tool 1098 for management. Instead of /dev/arX device names, use /dev/raid/rX. 1099 1100 No kernel config options or code have been removed, so if a problem 1101 arises, please report it and optionally revert to the old ATA stack. 1102 In order to do it you can remove from the kernel config: 1103 options ATA_CAM 1104 device ahci 1105 device mvs 1106 device siis 1107 , and instead add back: 1108 device atadisk # ATA disk drives 1109 device ataraid # ATA RAID drives 1110 device atapicd # ATAPI CDROM drives 1111 device atapifd # ATAPI floppy drives 1112 device atapist # ATAPI tape drives 1113 111420110423: 1115 The default NFS server has been changed to the new server, which 1116 was referred to as the experimental server. If you need to switch 1117 back to the old NFS server, you must now put the "-o" option on 1118 both the mountd and nfsd commands. This can be done using the 1119 mountd_flags and nfs_server_flags rc.conf variables until an 1120 update to the rc scripts is committed, which is coming soon. 1121 112220110418: 1123 The GNU Objective-C runtime library (libobjc), and other Objective-C 1124 related components have been removed from the base system. If you 1125 require an Objective-C library, please use one of the available ports. 1126 112720110331: 1128 ath(4) has been split into bus- and device- modules. if_ath contains 1129 the HAL, the TX rate control and the network device code. if_ath_pci 1130 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1131 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1132 in order to use ath on everything else. 1133 1134 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1135 need to load if_ath and if_ath_pci for ath(4) operation. 1136 113720110314: 1138 As part of the replacement of sysinstall, the process of building 1139 release media has changed significantly. For details, please re-read 1140 release(7), which has been updated to reflect the new build process. 1141 114220110218: 1143 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1144 is the last available version under GPLv2. It brings a number of new 1145 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1146 4.1 and SSE 4.2), better support for powerpc64, a number of new 1147 directives, and lots of other small improvements. See the ChangeLog 1148 file in contrib/binutils for the full details. 1149 115020110218: 1151 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1152 compliant, and will now use half of hash for authentication. 1153 This will break interoperability with all stacks (including all 1154 actual FreeBSD versions) who implement 1155 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1156 authentication). 1157 The only workaround with such peers is to use another HMAC 1158 algorithm for IPsec ("phase 2") authentication. 1159 116020110207: 1161 Remove the uio_yield prototype and symbol. This function has 1162 been misnamed since it was introduced and should not be 1163 globally exposed with this name. The equivalent functionality 1164 is now available using kern_yield(curthread->td_user_pri). 1165 The function remains undocumented. 1166 116720110112: 1168 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1169 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1170 for scalar sysctls is defined but disabled. Code that needs 1171 UQUAD to pass the type checking that must compile on older 1172 systems where the define is not present can check against 1173 __FreeBSD_version >= 900030. 1174 1175 The system dialog(1) has been replaced with a new version previously 1176 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1177 with the previous version, but the libdialog associated with it has 1178 a largely incompatible API. As such, the original version of libdialog 1179 will be kept temporarily as libodialog, until its base system consumers 1180 are replaced or updated. Bump __FreeBSD_version to 900030. 1181 118220110103: 1183 If you are trying to run make universe on a -stable system, and you get 1184 the following warning: 1185 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1186 unknown. config(8) likely too old." 1187 or something similar to it, then you must upgrade your -stable system 1188 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1189 stable/8) or build the config from the latest stable/8 branch and 1190 install it on your system. 1191 1192 Prior to this date, building a current universe on 8-stable system from 1193 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1194 error in the first kernel build phase. A new config on those old 1195 systems will fix that problem for older versions of -current. 1196 119720101228: 1198 The TCP stack has been modified to allow Khelp modules to interact with 1199 it via helper hook points and store per-connection data in the TCP 1200 control block. Bump __FreeBSD_version to 900029. User space tools that 1201 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1202 be recompiled. 1203 120420101114: 1205 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1206 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1207 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1208 to take advantage of it instead of using custom implementations. This 1209 means that these drivers now no longer unconditionally advertise 1210 support for flow control but only do so if flow control is a selected 1211 media option. This was implemented in the generic support that way in 1212 order to allow flow control to be switched on and off via ifconfig(8) 1213 with the PHY specific default to typically off in order to protect 1214 from unwanted effects. Consequently, if you used flow control with 1215 one of the above mentioned drivers you now need to explicitly enable 1216 it, for example via: 1217 ifconfig bge0 media auto mediaopt flowcontrol 1218 1219 Along with the above mentioned changes generic support for setting 1220 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1221 e1000phy(4) as well as ip1000phy(4) have been converted to take 1222 advantage of it. This means that these drivers now no longer take the 1223 link0 parameter for selecting master mode but the master media option 1224 has to be used instead, for example like in the following: 1225 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1226 1227 Selection of master mode now is also available with all other PHY 1228 drivers supporting 1000baseT. 1229 123020101111: 1231 The TCP stack has received a significant update to add support for 1232 modularised congestion control and generally improve the clarity of 1233 congestion control decisions. Bump __FreeBSD_version to 900025. User 1234 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1235 sockstat) need to be recompiled. 1236 123720101002: 1238 The man(1) utility has been replaced by a new version that no longer 1239 uses /etc/manpath.config. Please consult man.conf(5) for how to 1240 migrate local entries to the new format. 1241 124220100928: 1243 The copyright strings printed by login(1) and sshd(8) at the time of a 1244 new connection have been removed to follow other operating systems and 1245 upstream sshd. 1246 124720100915: 1248 A workaround for a fixed ld bug has been removed in kernel code, 1249 so make sure that your system ld is built from sources after 1250 revision 210245 from 2010-07-19 (r211583 if building head kernel 1251 on stable/8, r211584 for stable/7; both from 2010-08-21). 1252 A symptom of incorrect ld version is different addresses for 1253 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1254 125520100913: 1256 The $ipv6_prefer variable in rc.conf(5) has been split into 1257 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1258 1259 The $ip6addrctl_policy is a variable to choose a pre-defined 1260 address selection policy set by ip6addrctl(8). A value 1261 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1262 default is "AUTO". 1263 1264 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1265 flag (see an entry of 20090926) is set on an interface with no 1266 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1267 security reason. If you want IPv6 link-local address on all 1268 interfaces by default, set this to "YES". 1269 1270 The old ipv6_prefer="YES" is equivalent to 1271 ipv6_activate_all_interfaces="YES" and 1272 ip6addrctl_policy="ipv6_prefer". 1273 127420100913: 1275 DTrace has grown support for userland tracing. Due to this, DTrace is 1276 now i386 and amd64 only. 1277 dtruss(1) is now installed by default on those systems and a new 1278 kernel module is needed for userland tracing: fasttrap. 1279 No changes to your kernel config file are necessary to enable 1280 userland tracing, but you might consider adding 'STRIP=' and 1281 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1282 to have informative userland stack traces in DTrace (ustack). 1283 128420100725: 1285 The acpi_aiboost(4) driver has been removed in favor of the new 1286 aibs(4) driver. You should update your kernel configuration file. 1287 128820100722: 1289 BSD grep has been imported to the base system and it is built by 1290 default. It is completely BSD licensed, highly GNU-compatible, uses 1291 less memory than its GNU counterpart and has a small codebase. 1292 However, it is slower than its GNU counterpart, which is mostly 1293 noticeable for larger searches, for smaller ones it is measurable 1294 but not significant. The reason is complex, the most important factor 1295 is that we lack a modern and efficient regex library and GNU 1296 overcomes this by optimizing the searches internally. Future work 1297 on improving the regex performance is planned, for the meantime, 1298 users that need better performance, can build GNU grep instead by 1299 setting the WITH_GNU_GREP knob. 1300 130120100713: 1302 Due to the import of powerpc64 support, all existing powerpc kernel 1303 configuration files must be updated with a machine directive like this: 1304 machine powerpc powerpc 1305 1306 In addition, an updated config(8) is required to build powerpc kernels 1307 after this change. 1308 130920100713: 1310 A new version of ZFS (version 15) has been merged to -HEAD. 1311 This version uses a python library for the following subcommands: 1312 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1313 For full functionality of these commands the following port must 1314 be installed: sysutils/py-zfs 1315 131620100429: 1317 'vm_page's are now hashed by physical address to an array of mutexes. 1318 Currently this is only used to serialize access to hold_count. Over 1319 time the page queue mutex will be peeled away. This changes the size 1320 of pmap on every architecture. And requires all callers of vm_page_hold 1321 and vm_page_unhold to be updated. 1322 132320100402: 1324 WITH_CTF can now be specified in src.conf (not recommended, there 1325 are some problems with static executables), make.conf (would also 1326 affect ports which do not use GNU make and do not override the 1327 compile targets) or in the kernel config (via "makeoptions 1328 WITH_CTF=yes"). 1329 When WITH_CTF was specified there before this was silently ignored, 1330 so make sure that WITH_CTF is not used in places which could lead 1331 to unwanted behavior. 1332 133320100311: 1334 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1335 to allow 32-bit compatibility on non-x86 platforms. All kernel 1336 configurations on amd64 and ia64 platforms using these options must 1337 be modified accordingly. 1338 133920100113: 1340 The utmp user accounting database has been replaced with utmpx, 1341 the user accounting interface standardized by POSIX. 1342 Unfortunately the semantics of utmp and utmpx don't match, 1343 making it practically impossible to support both interfaces. 1344 The user accounting database is used by tools like finger(1), 1345 last(1), talk(1), w(1) and ac(8). 1346 1347 All applications in the base system use utmpx. This means only 1348 local binaries (e.g. from the ports tree) may still use these 1349 utmp database files. These applications must be rebuilt to make 1350 use of utmpx. 1351 1352 After the system has been upgraded, it is safe to remove the old 1353 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1354 assuming their contents is of no importance anymore. Old wtmp 1355 databases can only be used by last(1) and ac(8) after they have 1356 been converted to the new format using wtmpcvt(1). 1357 135820100108: 1359 Introduce the kernel thread "deadlock resolver" (which can be enabled 1360 via the DEADLKRES option, see NOTES for more details) and the 1361 sleepq_type() function for sleepqueues. 1362 136320091202: 1364 The rc.firewall and rc.firewall6 were unified, and 1365 rc.firewall6 and rc.d/ip6fw were removed. 1366 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1367 variables are obsoleted. Instead, the following new rc 1368 variables are added to rc.d/ipfw: 1369 1370 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1371 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1372 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1373 1374 The meanings correspond to the relevant IPv4 variables. 1375 137620091125: 1377 8.0-RELEASE. 1378 137920091113: 1380 The default terminal emulation for syscons(4) has been changed 1381 from cons25 to xterm on all platforms except pc98. This means 1382 that the /etc/ttys file needs to be updated to ensure correct 1383 operation of applications on the console. 1384 1385 The terminal emulation style can be toggled per window by using 1386 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1387 options can be used to change the compile-time default back to 1388 cons25. 1389 1390 To prevent graphical artifacts, make sure the TERM environment 1391 variable is set to match the terminal emulation that is being 1392 performed by syscons(4). 1393 139420091109: 1395 The layout of the structure ieee80211req_scan_result has changed. 1396 Applications that require wireless scan results (e.g. ifconfig(8)) 1397 from net80211 need to be recompiled. 1398 1399 Applications such as wpa_supplicant(8) may require a full world 1400 build without using NO_CLEAN in order to get synchronized with the 1401 new structure. 1402 140320091025: 1404 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1405 There's one kernel module for each firmware. Adding "device iwnfw" 1406 to the kernel configuration file means including all three firmware 1407 images inside the kernel. If you want to include just the one for 1408 your wireless card, use the devices iwn4965fw, iwn5000fw or 1409 iwn5150fw. 1410 141120090926: 1412 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1413 into rc.d/netif. The changes are the following: 1414 1415 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1416 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1417 Note that both variables need the "inet6" keyword at the head. 1418 1419 Do not set $ipv6_network_interfaces manually if you do not 1420 understand what you are doing. It is not needed in most cases. 1421 1422 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1423 they are obsolete. 1424 1425 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1426 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1427 1428 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1429 all configured interfaces have "inet6 accept_rtadv" in the 1430 $ifconfig_IF_ipv6. These are for backward compatibility. 1431 1432 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1433 functionality of interfaces with no corresponding 1434 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1435 and the default address selection policy of ip6addrctl(8) 1436 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1437 Note that if you want to configure IPv6 functionality on the 1438 disabled interfaces after boot, first you need to clear the flag by 1439 using ifconfig(8) like: 1440 1441 ifconfig em0 inet6 -ifdisabled 1442 1443 If YES, the default address selection policy is set as 1444 IPv6-preferred. 1445 1446 The default value of $ipv6_prefer is NO. 1447 1448 4. If your system need to receive Router Advertisement messages, 1449 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1450 scripts automatically invoke rtsol(8) when the interface becomes 1451 UP. The Router Advertisement messages are used for SLAAC 1452 (State-Less Address AutoConfiguration). 1453 145420090922: 1455 802.11s D3.03 support was committed. This is incompatible with the 1456 previous code, which was based on D3.0. 1457 145820090912: 1459 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1460 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1461 control whether accepting Router Advertisement messages or not. 1462 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1463 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1464 The ifconfig(8) utility now supports these flags. 1465 146620090910: 1467 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1468 mount(8) and -a option for df(1) to see them. 1469 147020090825: 1471 The old tunable hw.bus.devctl_disable has been superseded by 1472 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1473 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1474 is 1000. 1475 147620090813: 1477 Remove the option STOP_NMI. The default action is now to use NMI only 1478 for KDB via the newly introduced function stop_cpus_hard() and 1479 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1480 148120090803: 1482 The stable/8 branch created in subversion. This corresponds to the 1483 RELENG_8 branch in CVS. 1484 148520090719: 1486 Bump the shared library version numbers for all libraries that do not 1487 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1488 __FreeBSD_version to 800105. 1489 149020090714: 1491 Due to changes in the implementation of virtual network stack support, 1492 all network-related kernel modules must be recompiled. As this change 1493 breaks the ABI, bump __FreeBSD_version to 800104. 1494 149520090713: 1496 The TOE interface to the TCP syncache has been modified to remove 1497 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1498 The cxgb driver is the only TOE consumer affected by this change, and 1499 needs to be recompiled along with the kernel. As this change breaks 1500 the ABI, bump __FreeBSD_version to 800103. 1501 150220090712: 1503 Padding has been added to struct tcpcb, sackhint and tcpstat in 1504 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1505 maintaining the ABI. However, this change breaks the ABI, so bump 1506 __FreeBSD_version to 800102. User space tools that rely on the size of 1507 any of these structs (e.g. sockstat) need to be recompiled. 1508 150920090630: 1510 The NFS_LEGACYRPC option has been removed along with the old kernel 1511 RPC implementation that this option selected. Kernel configurations 1512 may need to be adjusted. 1513 151420090629: 1515 The network interface device nodes at /dev/net/<interface> have been 1516 removed. All ioctl operations can be performed the normal way using 1517 routing sockets. The kqueue functionality can generally be replaced 1518 with routing sockets. 1519 152020090628: 1521 The documentation from the FreeBSD Documentation Project (Handbook, 1522 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1523 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1524 152520090624: 1526 The ABI of various structures related to the SYSV IPC API have been 1527 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1528 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1529 800100. 1530 153120090622: 1532 Layout of struct vnet has changed as routing related variables were 1533 moved to their own Vimage module. Modules need to be recompiled. Bump 1534 __FreeBSD_version to 800099. 1535 153620090619: 1537 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1538 respectively. As long as no more than 16 groups per process are used, 1539 no changes should be visible. When more than 16 groups are used, old 1540 binaries may fail if they call getgroups() or getgrouplist() with 1541 statically sized storage. Recompiling will work around this, but 1542 applications should be modified to use dynamically allocated storage 1543 for group arrays as POSIX.1-2008 does not cap an implementation's 1544 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1545 1546 NFS and portalfs mounts may also be affected as the list of groups is 1547 truncated to 16. Users of NFS who use more than 16 groups, should 1548 take care that negative group permissions are not used on the exported 1549 file systems as they will not be reliable unless a GSSAPI based 1550 authentication method is used. 1551 155220090616: 1553 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1554 option compiles in the support for adaptive spinning for lockmgrs 1555 which want to enable it. The lockinit() function now accepts the flag 1556 LK_ADAPTIVE in order to make the lock object subject to adaptive 1557 spinning when both held in write and read mode. 1558 155920090613: 1560 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1561 changed. User applications that use this ioctl need to be rebuilt. 1562 156320090611: 1564 The layout of struct thread has changed. Kernel and modules need to 1565 be rebuilt. 1566 156720090608: 1568 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1569 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1570 157120090602: 1572 window(1) has been removed from the base system. It can now be 1573 installed from ports. The port is called misc/window. 1574 157520090601: 1576 The way we are storing and accessing `routing table' entries has 1577 changed. Programs reading the FIB, like netstat, need to be 1578 re-compiled. 1579 158020090601: 1581 A new netisr implementation has been added for FreeBSD 8. Network 1582 file system modules, such as igmp, ipdivert, and others, should be 1583 rebuilt. 1584 Bump __FreeBSD_version to 800096. 1585 158620090530: 1587 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1588 more valid. 1589 159020090530: 1591 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1592 Bump __FreeBSD_version to 800094. 1593 159420090529: 1595 Add mnt_xflag field to 'struct mount'. File system modules need to be 1596 rebuilt. 1597 Bump __FreeBSD_version to 800093. 1598 159920090528: 1600 The compiling option ADAPTIVE_SX has been retired while it has been 1601 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1602 The KPI for sx_init_flags() changes as accepting flags: 1603 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1604 been introduced in order to handle the reversed logic. 1605 Bump __FreeBSD_version to 800092. 1606 160720090527: 1608 Add support for hierarchical jails. Remove global securelevel. 1609 Bump __FreeBSD_version to 800091. 1610 161120090523: 1612 The layout of struct vnet_net has changed, therefore modules 1613 need to be rebuilt. 1614 Bump __FreeBSD_version to 800090. 1615 161620090523: 1617 The newly imported zic(8) produces a new format in the output. Please 1618 run tzsetup(8) to install the newly created data to /etc/localtime. 1619 162020090520: 1621 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1622 hw.usb.* and is now consistent again with previous releases. 1623 162420090520: 1625 802.11 monitor mode support was revised and driver api's were changed. 1626 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1627 of DLT_IEEE802_11. No user-visible data structures were changed but 1628 applications that use DLT_IEEE802_11 may require changes. 1629 Bump __FreeBSD_version to 800088. 1630 163120090430: 1632 The layout of the following structs has changed: sysctl_oid, 1633 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1634 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1635 panics may be experienced. World rebuild is required for 1636 correctly checking networking state from userland. 1637 Bump __FreeBSD_version to 800085. 1638 163920090429: 1640 MLDv2 and Source-Specific Multicast (SSM) have been merged 1641 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1642 The implementation of SSM within FreeBSD's IPv6 stack closely 1643 follows the IPv4 implementation. 1644 1645 For kernel developers: 1646 1647 * The most important changes are that the ip6_output() and 1648 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1649 and this lock has been downgraded to a non-recursive mutex. 1650 1651 * As with the changes to the IPv4 stack to support SSM, filtering 1652 of inbound multicast traffic must now be performed by transport 1653 protocols within the IPv6 stack. This does not apply to TCP and 1654 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1655 1656 * The KPIs used by IPv6 multicast are similar to those used by 1657 the IPv4 stack, with the following differences: 1658 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1659 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1660 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1661 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1662 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1663 for MLDv1 have an additional 'timer' argument which is used to 1664 jitter the initial membership report for the solicited-node 1665 multicast membership on-link. 1666 * This is not strictly needed for MLDv2, which already jitters 1667 its report transmissions. However, the 'timer' argument is 1668 preserved in case MLDv1 is active on the interface. 1669 1670 * The KAME linked-list based IPv6 membership implementation has 1671 been refactored to use a vector similar to that used by the IPv4 1672 stack. 1673 Code which maintains a list of its own multicast memberships 1674 internally, e.g. carp, has been updated to reflect the new 1675 semantics. 1676 1677 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1678 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1679 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1680 implementation constraint which needs to be addressed in HEAD. 1681 1682 For application developers: 1683 1684 * The changes are broadly similar to those made for the IPv4 1685 stack. 1686 1687 * The use of IPv4 and IPv6 multicast socket options on the same 1688 socket, using mapped addresses, HAS NOT been tested or supported. 1689 1690 * There are a number of issues with the implementation of various 1691 IPv6 multicast APIs which need to be resolved in the API surface 1692 before the implementation is fully compatible with KAME userland 1693 use, and these are mostly to do with interface index treatment. 1694 1695 * The literature available discusses the use of either the delta / ASM 1696 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1697 using setsourcefilter(3)/getsourcefilter(3). For more information 1698 please refer to RFC 3768, 'Socket Interface Extensions for 1699 Multicast Source Filters'. 1700 1701 * Applications which use the published RFC 3678 APIs should be fine. 1702 1703 For systems administrators: 1704 1705 * The mtest(8) utility has been refactored to support IPv6, in 1706 addition to IPv4. Interface addresses are no longer accepted 1707 as arguments, their names must be used instead. The utility 1708 will map the interface name to its first IPv4 address as 1709 returned by getifaddrs(3). 1710 1711 * The ifmcstat(8) utility has also been updated to print the MLDv2 1712 endpoint state and source filter lists via sysctl(3). 1713 1714 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1715 loopback of IPv6 multicast datagrams by default; it defaults to 1 1716 to preserve the existing behaviour. Disabling multicast loopback is 1717 recommended for optimal system performance. 1718 1719 * The IPv6 MROUTING code has been changed to examine this sysctl 1720 instead of attempting to perform a group lookup before looping 1721 back forwarded datagrams. 1722 1723 Bump __FreeBSD_version to 800084. 1724 172520090422: 1726 Implement low-level Bluetooth HCI API. 1727 Bump __FreeBSD_version to 800083. 1728 172920090419: 1730 The layout of struct malloc_type, used by modules to register new 1731 memory allocation types, has changed. Most modules will need to 1732 be rebuilt or panics may be experienced. 1733 Bump __FreeBSD_version to 800081. 1734 173520090415: 1736 Anticipate overflowing inp_flags - add inp_flags2. 1737 This changes most offsets in inpcb, so checking v4 connection 1738 state will require a world rebuild. 1739 Bump __FreeBSD_version to 800080. 1740 174120090415: 1742 Add an llentry to struct route and struct route_in6. Modules 1743 embedding a struct route will need to be recompiled. 1744 Bump __FreeBSD_version to 800079. 1745 174620090414: 1747 The size of rt_metrics_lite and by extension rtentry has changed. 1748 Networking administration apps will need to be recompiled. 1749 The route command now supports show as an alias for get, weighting 1750 of routes, sticky and nostick flags to alter the behavior of stateful 1751 load balancing. 1752 Bump __FreeBSD_version to 800078. 1753 175420090408: 1755 Do not use Giant for kbdmux(4) locking. This is wrong and 1756 apparently causing more problems than it solves. This will 1757 re-open the issue where interrupt handlers may race with 1758 kbdmux(4) in polling mode. Typical symptoms include (but 1759 not limited to) duplicated and/or missing characters when 1760 low level console functions (such as gets) are used while 1761 interrupts are enabled (for example geli password prompt, 1762 mountroot prompt etc.). Disabling kbdmux(4) may help. 1763 176420090407: 1765 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1766 kernel modules referencing any of the above need to be recompiled. 1767 Bump __FreeBSD_version to 800075. 1768 176920090320: 1770 GEOM_PART has become the default partition slicer for storage devices, 1771 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1772 introduces some changes: 1773 1774 MSDOS/EBR: the devices created from MSDOS extended partition entries 1775 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1776 to devices with offset-based names. fstabs may need to be modified. 1777 1778 BSD: the "geometry does not match label" warning is harmless in most 1779 cases but it points to problems in file system misalignment with 1780 disk geometry. The "c" partition is now implicit, covers the whole 1781 top-level drive and cannot be (mis)used by users. 1782 1783 General: Kernel dumps are now not allowed to be written to devices 1784 whose partition types indicate they are meant to be used for file 1785 systems (or, in case of MSDOS partitions, as something else than 1786 the "386BSD" type). 1787 1788 Most of these changes date approximately from 200812. 1789 179020090319: 1791 The uscanner(4) driver has been removed from the kernel. This follows 1792 Linux removing theirs in 2.6 and making libusb the default interface 1793 (supported by sane). 1794 179520090319: 1796 The multicast forwarding code has been cleaned up. netstat(1) 1797 only relies on KVM now for printing bandwidth upcall meters. 1798 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1799 ip6_mroute_mod respectively. The config(5) options for statically 1800 compiling this code remain the same, i.e. 'options MROUTING'. 1801 180220090315: 1803 Support for the IFF_NEEDSGIANT network interface flag has been 1804 removed, which means that non-MPSAFE network device drivers are no 1805 longer supported. In particular, if_ar, if_sr, and network device 1806 drivers from the old (legacy) USB stack can no longer be built or 1807 used. 1808 180920090313: 1810 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1811 a bunch of new language catalog files have also been added. 1812 This means that some common libc messages are now localized and 1813 they depend on the LC_MESSAGES environmental variable. 1814 181520090313: 1816 The k8temp(4) driver has been renamed to amdtemp(4) since 1817 support for Family 10 and Family 11 CPU families was added. 1818 181920090309: 1820 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1821 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1822 1823 For kernel developers, the most important changes are that the 1824 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1825 and this lock has been downgraded to a non-recursive mutex. 1826 1827 Transport protocols (UDP, Raw IP) are now responsible for filtering 1828 inbound multicast traffic according to group membership and source 1829 filters. The imo_multicast_filter() KPI exists for this purpose. 1830 Transports which do not use multicast (SCTP, TCP) already reject 1831 multicast by default. Forwarding and receive performance may improve 1832 as a mutex acquisition is no longer needed in the ip_input() 1833 low-level input path. in_addmulti() and in_delmulti() are shimmed 1834 to new KPIs which exist to support SSM in-kernel. 1835 1836 For application developers, it is recommended that loopback of 1837 multicast datagrams be disabled for best performance, as this 1838 will still cause the lock to be taken for each looped-back 1839 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1840 be tuned to 0 to disable loopback by default; it defaults to 1 1841 to preserve the existing behaviour. 1842 1843 For systems administrators, to obtain best performance with 1844 multicast reception and multiple groups, it is always recommended 1845 that a card with a suitably precise hash filter is used. Hash 1846 collisions will still result in the lock being taken within the 1847 transport protocol input path to check group membership. 1848 1849 If deploying FreeBSD in an environment with IGMP snooping switches, 1850 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1851 enabled; this forces 224.0.0.0/24 group membership to be announced 1852 via IGMP. 1853 1854 The size of 'struct igmpstat' has changed; netstat needs to be 1855 recompiled to reflect this. 1856 Bump __FreeBSD_version to 800070. 1857 185820090309: 1859 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1860 updated to use it. This requires a buildworld/installworld in order to 1861 update the library and dependencies (usbconfig, etc). Its advisable to 1862 rebuild all ports which uses libusb. More specific directions are given 1863 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1864 libusb are no longer required and can be removed. 1865 186620090302: 1867 A workaround is committed to allow the creation of System V shared 1868 memory segment of size > 2 GB on the 64-bit architectures. 1869 Due to a limitation of the existing ABI, the shm_segsz member 1870 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1871 wrong for large segments. Note that limits must be explicitly 1872 raised to allow such segments to be created. 1873 187420090301: 1875 The layout of struct ifnet has changed, requiring a rebuild of all 1876 network device driver modules. 1877 187820090227: 1879 The /dev handling for the new USB stack has changed, a 1880 buildworld/installworld is required for libusb20. 1881 188220090223: 1883 The new USB2 stack has now been permanently moved in and all kernel and 1884 module names reverted to their previous values (eg, usb, ehci, ohci, 1885 ums, ...). The old usb stack can be compiled in by prefixing the name 1886 with the letter 'o', the old usb modules have been removed. 1887 Updating entry 20090216 for xorg and 20090215 for libmap may still 1888 apply. 1889 189020090217: 1891 The rc.conf(5) option if_up_delay has been renamed to 1892 defaultroute_delay to better reflect its purpose. If you have 1893 customized this setting in /etc/rc.conf you need to update it to 1894 use the new name. 1895 189620090216: 1897 xorg 7.4 wants to configure its input devices via hald which does not 1898 yet work with USB2. If the keyboard/mouse does not work in xorg then 1899 add 1900 Option "AllowEmptyInput" "off" 1901 to your ServerLayout section. This will cause X to use the configured 1902 kbd and mouse sections from your xorg.conf. 1903 190420090215: 1905 The GENERIC kernels for all architectures now default to the new USB2 1906 stack. No kernel config options or code have been removed so if a 1907 problem arises please report it and optionally revert to the old USB 1908 stack. If you are loading USB kernel modules or have a custom kernel 1909 that includes GENERIC then ensure that usb names are also changed over, 1910 eg uftdi -> usb2_serial_ftdi. 1911 1912 Older programs linked against the ports libusb 0.1 need to be 1913 redirected to the new stack's libusb20. /etc/libmap.conf can 1914 be used for this: 1915 # Map old usb library to new one for usb2 stack 1916 libusb-0.1.so.8 libusb20.so.1 1917 191820090209: 1919 All USB ethernet devices now attach as interfaces under the name ueN 1920 (eg. ue0). This is to provide a predictable name as vendors often 1921 change usb chipsets in a product without notice. 1922 192320090203: 1924 The ichsmb(4) driver has been changed to require SMBus slave 1925 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1926 All of the other SMBus controller drivers require left-justified 1927 slave addresses, so this change makes all the drivers provide the 1928 same interface. 1929 193020090201: 1931 INET6 statistics (struct ip6stat) was updated. 1932 netstat(1) needs to be recompiled. 1933 193420090119: 1935 NTFS has been removed from GENERIC kernel on amd64 to match 1936 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1937 will load ntfs.ko module automatically when NTFS support is 1938 actually needed, unless ntfs.ko is not installed or security 1939 level prohibits loading kernel modules. If either is the case, 1940 "options NTFS" has to be added into kernel config. 1941 194220090115: 1943 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1944 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1945 800061. User space tools that rely on the size of struct tcpcb in 1946 tcp_var.h (e.g. sockstat) need to be recompiled. 1947 194820081225: 1949 ng_tty(4) module updated to match the new TTY subsystem. 1950 Due to API change, user-level applications must be updated. 1951 New API support added to mpd5 CVS and expected to be present 1952 in next mpd5.3 release. 1953 195420081219: 1955 With __FreeBSD_version 800060 the makefs tool is part of 1956 the base system (it was a port). 1957 195820081216: 1959 The afdata and ifnet locks have been changed from mutexes to 1960 rwlocks, network modules will need to be re-compiled. 1961 196220081214: 1963 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1964 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1965 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1966 architecture and 40 bytes on 64-bit architecture. The userland 1967 applications "arp" and "ndp" have been updated accordingly. 1968 The output from "netstat -r" shows only routing entries and 1969 none of the L2 information. 1970 197120081130: 1972 __FreeBSD_version 800057 marks the switchover from the 1973 binary ath hal to source code. Users must add the line: 1974 1975 options AH_SUPPORT_AR5416 1976 1977 to their kernel config files when specifying: 1978 1979 device ath_hal 1980 1981 The ath_hal module no longer exists; the code is now compiled 1982 together with the driver in the ath module. It is now 1983 possible to tailor chip support (i.e. reduce the set of chips 1984 and thereby the code size); consult ath_hal(4) for details. 1985 198620081121: 1987 __FreeBSD_version 800054 adds memory barriers to 1988 <machine/atomic.h>, new interfaces to ifnet to facilitate 1989 multiple hardware transmit queues for cards that support 1990 them, and a lock-less ring-buffer implementation to 1991 enable drivers to more efficiently manage queueing of 1992 packets. 1993 199420081117: 1995 A new version of ZFS (version 13) has been merged to -HEAD. 1996 This version has zpool attribute "listsnapshots" off by 1997 default, which means "zfs list" does not show snapshots, 1998 and is the same as Solaris behavior. 1999 200020081028: 2001 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 2002 200320081009: 2004 The uhci, ohci, ehci and slhci USB Host controller drivers have 2005 been put into separate modules. If you load the usb module 2006 separately through loader.conf you will need to load the 2007 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 2008 controller add the following to loader.conf: 2009 2010 uhci_load="YES" 2011 ehci_load="YES" 2012 201320081009: 2014 The ABI used by the PMC toolset has changed. Please keep 2015 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 2016 sync. 2017 201820081009: 2019 atapci kernel module now includes only generic PCI ATA 2020 driver. AHCI driver moved to ataahci kernel module. 2021 All vendor-specific code moved into separate kernel modules: 2022 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 2023 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 2024 atamarvell, atamicron, atanational, atanetcell, atanvidia, 2025 atapromise, ataserverworks, atasiliconimage, atasis, atavia 2026 202720080820: 2028 The TTY subsystem of the kernel has been replaced by a new 2029 implementation, which provides better scalability and an 2030 improved driver model. Most common drivers have been migrated to 2031 the new TTY subsystem, while others have not. The following 2032 drivers have not yet been ported to the new TTY layer: 2033 2034 PCI/ISA: 2035 cy, digi, rc, rp, sio 2036 2037 USB: 2038 ubser, ucycom 2039 2040 Line disciplines: 2041 ng_h4, ng_tty, ppp, sl, snp 2042 2043 Adding these drivers to your kernel configuration file shall 2044 cause compilation to fail. 2045 204620080818: 2047 ntpd has been upgraded to 4.2.4p5. 2048 204920080801: 2050 OpenSSH has been upgraded to 5.1p1. 2051 2052 For many years, FreeBSD's version of OpenSSH preferred DSA 2053 over RSA for host and user authentication keys. With this 2054 upgrade, we've switched to the vendor's default of RSA over 2055 DSA. This may cause upgraded clients to warn about unknown 2056 host keys even for previously known hosts. Users should 2057 follow the usual procedure for verifying host keys before 2058 accepting the RSA key. 2059 2060 This can be circumvented by setting the "HostKeyAlgorithms" 2061 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 2062 command line. 2063 2064 Please note that the sequence of keys offered for 2065 authentication has been changed as well. You may want to 2066 specify IdentityFile in a different order to revert this 2067 behavior. 2068 206920080713: 2070 The sio(4) driver has been removed from the i386 and amd64 2071 kernel configuration files. This means uart(4) is now the 2072 default serial port driver on those platforms as well. 2073 2074 To prevent collisions with the sio(4) driver, the uart(4) driver 2075 uses different names for its device nodes. This means the 2076 onboard serial port will now most likely be called "ttyu0" 2077 instead of "ttyd0". You may need to reconfigure applications to 2078 use the new device names. 2079 2080 When using the serial port as a boot console, be sure to update 2081 /boot/device.hints and /etc/ttys before booting the new kernel. 2082 If you forget to do so, you can still manually specify the hints 2083 at the loader prompt: 2084 2085 set hint.uart.0.at="isa" 2086 set hint.uart.0.port="0x3F8" 2087 set hint.uart.0.flags="0x10" 2088 set hint.uart.0.irq="4" 2089 boot -s 2090 209120080609: 2092 The gpt(8) utility has been removed. Use gpart(8) to partition 2093 disks instead. 2094 209520080603: 2096 The version that Linuxulator emulates was changed from 2.4.2 2097 to 2.6.16. If you experience any problems with Linux binaries 2098 please try to set sysctl compat.linux.osrelease to 2.4.2 and 2099 if it fixes the problem contact emulation mailing list. 2100 210120080525: 2102 ISDN4BSD (I4B) was removed from the src tree. You may need to 2103 update a your kernel configuration and remove relevant entries. 2104 210520080509: 2106 I have checked in code to support multiple routing tables. 2107 See the man pages setfib(1) and setfib(2). 2108 This is a hopefully backwards compatible version, 2109 but to make use of it you need to compile your kernel 2110 with options ROUTETABLES=2 (or more up to 16). 2111 211220080420: 2113 The 802.11 wireless support was redone to enable multi-bss 2114 operation on devices that are capable. The underlying device 2115 is no longer used directly but instead wlanX devices are 2116 cloned with ifconfig. This requires changes to rc.conf files. 2117 For example, change: 2118 ifconfig_ath0="WPA DHCP" 2119 to 2120 wlans_ath0=wlan0 2121 ifconfig_wlan0="WPA DHCP" 2122 see rc.conf(5) for more details. In addition, mergemaster of 2123 /etc/rc.d is highly recommended. Simultaneous update of userland 2124 and kernel wouldn't hurt either. 2125 2126 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2127 modules were merged into the base wlan module. All references 2128 to these modules (e.g. in kernel config files) must be removed. 2129 213020080408: 2131 psm(4) has gained write(2) support in native operation level. 2132 Arbitrary commands can be written to /dev/psm%d and status can 2133 be read back from it. Therefore, an application is responsible 2134 for status validation and error recovery. It is a no-op in 2135 other operation levels. 2136 213720080312: 2138 Support for KSE threading has been removed from the kernel. To 2139 run legacy applications linked against KSE libmap.conf may 2140 be used. The following libmap.conf may be used to ensure 2141 compatibility with any prior release: 2142 2143 libpthread.so.1 libthr.so.1 2144 libpthread.so.2 libthr.so.2 2145 libkse.so.3 libthr.so.3 2146 214720080301: 2148 The layout of struct vmspace has changed. This affects libkvm 2149 and any executables that link against libkvm and use the 2150 kvm_getprocs() function. In particular, but not exclusively, 2151 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2152 The effects are minimal, but it's advisable to upgrade world 2153 nonetheless. 2154 215520080229: 2156 The latest em driver no longer has support in it for the 2157 82575 adapter, this is now moved to the igb driver. The 2158 split was done to make new features that are incompatible 2159 with older hardware easier to do. 2160 216120080220: 2162 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2163 likewise the kernel option is now GEOM_LINUX_LVM. 2164 216520080211: 2166 The default NFS mount mode has changed from UDP to TCP for 2167 increased reliability. If you rely on (insecurely) NFS 2168 mounting across a firewall you may need to update your 2169 firewall rules. 2170 217120080208: 2172 Belatedly note the addition of m_collapse for compacting 2173 mbuf chains. 2174 217520080126: 2176 The fts(3) structures have been changed to use adequate 2177 integer types for their members and so to be able to cope 2178 with huge file trees. The old fts(3) ABI is preserved 2179 through symbol versioning in libc, so third-party binaries 2180 using fts(3) should still work, although they will not take 2181 advantage of the extended types. At the same time, some 2182 third-party software might fail to build after this change 2183 due to unportable assumptions made in its source code about 2184 fts(3) structure members. Such software should be fixed 2185 by its vendor or, in the worst case, in the ports tree. 2186 FreeBSD_version 800015 marks this change for the unlikely 2187 case that a portable fix is impossible. 2188 218920080123: 2190 To upgrade to -current after this date, you must be running 2191 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2192 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2193 219420071128: 2195 The ADAPTIVE_GIANT kernel option has been retired because its 2196 functionality is the default now. 2197 219820071118: 2199 The AT keyboard emulation of sunkbd(4) has been turned on 2200 by default. In order to make the special symbols of the Sun 2201 keyboards driven by sunkbd(4) work under X these now have 2202 to be configured the same way as Sun USB keyboards driven 2203 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2204 2205 Option "XkbLayout" "us" 2206 Option "XkbRules" "xorg" 2207 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2208 220920071024: 2210 It has been decided that it is desirable to provide ABI 2211 backwards compatibility to the FreeBSD 4/5/6 versions of the 2212 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2213 broken with the introduction of PCI domain support (see the 2214 20070930 entry). Unfortunately, this required the ABI of 2215 PCIOCGETCONF to be broken again in order to be able to 2216 provide backwards compatibility to the old version of that 2217 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2218 again. As for prominent ports this affects neither pciutils 2219 nor xorg-server this time, the hal port needs to be rebuilt 2220 however. 2221 222220071020: 2223 The misnamed kthread_create() and friends have been renamed 2224 to kproc_create() etc. Many of the callers already 2225 used kproc_start().. 2226 I will return kthread_create() and friends in a while 2227 with implementations that actually create threads, not procs. 2228 Renaming corresponds with version 800002. 2229 223020071010: 2231 RELENG_7 branched. 2232 2233COMMON ITEMS: 2234 2235 General Notes 2236 ------------- 2237 Avoid using make -j when upgrading. While generally safe, there are 2238 sometimes problems using -j to upgrade. If your upgrade fails with 2239 -j, please try again without -j. From time to time in the past there 2240 have been problems using -j with buildworld and/or installworld. This 2241 is especially true when upgrading between "distant" versions (eg one 2242 that cross a major release boundary or several minor releases, or when 2243 several months have passed on the -current branch). 2244 2245 Sometimes, obscure build problems are the result of environment 2246 poisoning. This can happen because the make utility reads its 2247 environment when searching for values for global variables. To run 2248 your build attempts in an "environmental clean room", prefix all make 2249 commands with 'env -i '. See the env(1) manual page for more details. 2250 2251 When upgrading from one major version to another it is generally best 2252 to upgrade to the latest code in the currently installed branch first, 2253 then do an upgrade to the new branch. This is the best-tested upgrade 2254 path, and has the highest probability of being successful. Please try 2255 this approach before reporting problems with a major version upgrade. 2256 2257 When upgrading a live system, having a root shell around before 2258 installing anything can help undo problems. Not having a root shell 2259 around can lead to problems if pam has changed too much from your 2260 starting point to allow continued authentication after the upgrade. 2261 2262 ZFS notes 2263 --------- 2264 When upgrading the boot ZFS pool to a new version, always follow 2265 these two steps: 2266 2267 1.) recompile and reinstall the ZFS boot loader and boot block 2268 (this is part of "make buildworld" and "make installworld") 2269 2270 2.) update the ZFS boot block on your boot drive 2271 2272 The following example updates the ZFS boot block on the first 2273 partition (freebsd-boot) of a GPT partitioned drive ad0: 2274 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2275 2276 Non-boot pools do not need these updates. 2277 2278 To build a kernel 2279 ----------------- 2280 If you are updating from a prior version of FreeBSD (even one just 2281 a few days old), you should follow this procedure. It is the most 2282 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2283 2284 make kernel-toolchain 2285 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2286 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2287 2288 To test a kernel once 2289 --------------------- 2290 If you just want to boot a kernel once (because you are not sure 2291 if it works, or if you want to boot a known bad kernel to provide 2292 debugging information) run 2293 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2294 nextboot -k testkernel 2295 2296 To just build a kernel when you know that it won't mess you up 2297 -------------------------------------------------------------- 2298 This assumes you are already running a CURRENT system. Replace 2299 ${arch} with the architecture of your machine (e.g. "i386", 2300 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2301 2302 cd src/sys/${arch}/conf 2303 config KERNEL_NAME_HERE 2304 cd ../compile/KERNEL_NAME_HERE 2305 make depend 2306 make 2307 make install 2308 2309 If this fails, go to the "To build a kernel" section. 2310 2311 To rebuild everything and install it on the current system. 2312 ----------------------------------------------------------- 2313 # Note: sometimes if you are running current you gotta do more than 2314 # is listed here if you are upgrading from a really old current. 2315 2316 <make sure you have good level 0 dumps> 2317 make buildworld 2318 make kernel KERNCONF=YOUR_KERNEL_HERE 2319 [1] 2320 <reboot in single user> [3] 2321 mergemaster -p [5] 2322 make installworld 2323 mergemaster -i [4] 2324 make delete-old [6] 2325 <reboot> 2326 2327 To cross-install current onto a separate partition 2328 -------------------------------------------------- 2329 # In this approach we use a separate partition to hold 2330 # current's root, 'usr', and 'var' directories. A partition 2331 # holding "/", "/usr" and "/var" should be about 2GB in 2332 # size. 2333 2334 <make sure you have good level 0 dumps> 2335 <boot into -stable> 2336 make buildworld 2337 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2338 <maybe newfs current's root partition> 2339 <mount current's root partition on directory ${CURRENT_ROOT}> 2340 make installworld DESTDIR=${CURRENT_ROOT} 2341 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2342 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2343 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2344 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2345 <reboot into current> 2346 <do a "native" rebuild/install as described in the previous section> 2347 <maybe install compatibility libraries from ports/misc/compat*> 2348 <reboot> 2349 2350 2351 To upgrade in-place from stable to current 2352 ---------------------------------------------- 2353 <make sure you have good level 0 dumps> 2354 make buildworld [9] 2355 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2356 [1] 2357 <reboot in single user> [3] 2358 mergemaster -p [5] 2359 make installworld 2360 mergemaster -i [4] 2361 make delete-old [6] 2362 <reboot> 2363 2364 Make sure that you've read the UPDATING file to understand the 2365 tweaks to various things you need. At this point in the life 2366 cycle of current, things change often and you are on your own 2367 to cope. The defaults can also change, so please read ALL of 2368 the UPDATING entries. 2369 2370 Also, if you are tracking -current, you must be subscribed to 2371 freebsd-current@freebsd.org. Make sure that before you update 2372 your sources that you have read and understood all the recent 2373 messages there. If in doubt, please track -stable which has 2374 much fewer pitfalls. 2375 2376 [1] If you have third party modules, such as vmware, you 2377 should disable them at this point so they don't crash your 2378 system on reboot. 2379 2380 [3] From the bootblocks, boot -s, and then do 2381 fsck -p 2382 mount -u / 2383 mount -a 2384 cd src 2385 adjkerntz -i # if CMOS is wall time 2386 Also, when doing a major release upgrade, it is required that 2387 you boot into single user mode to do the installworld. 2388 2389 [4] Note: This step is non-optional. Failure to do this step 2390 can result in a significant reduction in the functionality of the 2391 system. Attempting to do it by hand is not recommended and those 2392 that pursue this avenue should read this file carefully, as well 2393 as the archives of freebsd-current and freebsd-hackers mailing lists 2394 for potential gotchas. The -U option is also useful to consider. 2395 See mergemaster(8) for more information. 2396 2397 [5] Usually this step is a noop. However, from time to time 2398 you may need to do this if you get unknown user in the following 2399 step. It never hurts to do it all the time. You may need to 2400 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2401 install) after the buildworld before this step if you last updated 2402 from current before 20130425 or from -stable before 20130430. 2403 2404 [6] This only deletes old files and directories. Old libraries 2405 can be deleted by "make delete-old-libs", but you have to make 2406 sure that no program is using those libraries anymore. 2407 2408 [8] In order to have a kernel that can run the 4.x binaries needed to 2409 do an installworld, you must include the COMPAT_FREEBSD4 option in 2410 your kernel. Failure to do so may leave you with a system that is 2411 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2412 required to run the 5.x binaries on more recent kernels. And so on 2413 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2414 2415 Make sure that you merge any new devices from GENERIC since the 2416 last time you updated your kernel config file. 2417 2418 [9] When checking out sources, you must include the -P flag to have 2419 cvs prune empty directories. 2420 2421 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2422 "?=" instead of the "=" assignment operator, so that buildworld can 2423 override the CPUTYPE if it needs to. 2424 2425 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2426 not on the command line, or in /etc/make.conf. buildworld will 2427 warn if it is improperly defined. 2428FORMAT: 2429 2430This file contains a list, in reverse chronological order, of major 2431breakages in tracking -current. It is not guaranteed to be a complete 2432list of such breakages, and only contains entries since October 10, 2007. 2433If you need to see UPDATING entries from before that date, you will need 2434to fetch an UPDATING file from an older FreeBSD release. 2435 2436Copyright information: 2437 2438Copyright 1998-2009 M.
