1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. 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 1920151205 p25 FreeBSD-SA-15:26.openssl 20 21 Fix multiple OpenSSL vulnerabilities. [SA-15:26] 22 2320151104 p24 FreeBSD-SA-15:25.ntp [revised] 24 FreeBSD-EN-15:19.kqueue 25 FreeBSD-EN-15:20.vm 26 27 Fix regression in ntpd(8) lacking support for RAWDCF reference 28 clock in 10.1-RELEASE-p23. [SA-15:25.ntp] 29 30 Fix kqueue write events never fired for files greater 2GB. [EN-15:19] 31 32 Fix applications exiting due to segmentation violation on a correct 33 memory address. [EN-15:20] 34 3520151026: p23 FreeBSD-SA-15:25.ntp 36 37 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 38 39 The configuration file syntax has been changed, thus mergemaster 40 run is recommended. Now the "kod" parameter requires "limited" 41 parameter. If the ntp.conf is not updated, the ntpd will run 42 successfully, but with KoD disabled. 43 4420151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 45 Revised patch to address a regression that prevents NIS from working. 46 4720150929: p21 FreeBSD-SA-15:24.rpcbind 48 49 Fix rpcbind(8) remote denial of service.

[SA-15:01] 173 17420141223: p3 FreeBSD-SA-14:31.ntp 175 FreeBSD-EN-14:13.freebsd-update 176 177 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 178 Fix directory deletion issue in freebsd-update. [EN-14:13] 179 18020141217: p2 FreeBSD-SA-14:30.unbound 181 Fix unbound remote denial of service vulnerability. 182 18320141210: p1 FreeBSD-SA-14:27.stdio 184 FreeBSD-SA-14:28.file 185 186 Fix buffer overflow in stdio. [SA-14:27] 187 188 Fix multiple vulnerabilities in file(1) and libmagic(3). 189 [SA-14:28] 190 19120140904: 192 The ofwfb driver, used to provide a graphics console on PowerPC when 193 using vt(4), no longer allows mmap() of all of physical memory. This 194 will prevent Xorg on PowerPC with some ATI graphics cards from 195 initializing properly unless x11-servers/xorg-server is updated to 196 1.12.4_8 or newer. 197 19820140831: 199 The libatf-c and libatf-c++ major versions were downgraded to 0 and 200 1 respectively to match the upstream numbers. They were out of 201 sync because, when they were originally added to FreeBSD, the 202 upstream versions were not respected. These libraries are private 203 and not yet built by default, so renumbering them should be a 204 non-issue. However, unclean source trees will yield broken test 205 programs once the operator executes "make delete-old-libs" after a 206 "make installworld". 207 208 Additionally, the atf-sh binary was made private by moving it into 209 /usr/libexec/. Already-built shell test programs will keep the 210 path to the old binary so they will break after "make delete-old" 211 is run. 212 213 If you are using WITH_TESTS=yes (not the default), wipe the object 214 tree and rebuild from scratch to prevent spurious test failures. 215 This is only needed once: the misnumbered libraries and misplaced 216 binaries have been added to OptionalObsoleteFiles.inc so they will 217 be removed during a clean upgrade. 218 21920140814: 220 The ixgbe tunables now match their sysctl counterparts, for example: 221 hw.ixgbe.enable_aim => hw.ix.enable_aim 222 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 223 22420140801: 225 The NFSv4.1 server committed by r269398 changes the internal 226 function call interfaces used between the NFS and krpc modules. 227 As such, __FreeBSD_version was bumped. 228 22920140729: 230 The default unbound configuration has been modified to address 231 issues with reverse lookups on networks that use private 232 address ranges. If you use the local_unbound service, run 233 "service local_unbound setup" as root to regenerate your 234 configuration, then "service local_unbound reload" to load the 235 new configuration. 236 23720140717: 238 It is no longer necessary to include the dwarf version in your DEBUG 239 options in your kernel config file. The bug that required it to be 240 placed in the config file has bene fixed. DEBUG should now just 241 contain -g. The build system will automatically update things 242 to do the right thing. 243 24420140715: 245 Several ABI breaking changes were merged to CTL and new iSCSI code. 246 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 247 iscsictl need to be rebuilt to work with a new kernel. 248 24920140708: 250 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 251 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 252 which differs from the behaviour controlled by this knob.) 253 25420140608: 255 On i386 and amd64 systems, the onifconsole flag is now set by default 256 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 257 as a login TTY if it is set in the bootloader as an active kernel 258 console. No changes in behavior should result otherwise. To revert to 259 the previous behavior, set ttyu0 to "off" in /etc/ttys. 260 26120140512: 262 Clang and llvm have been upgraded to 3.4.1 release. 263 26420140321: 265 Clang and llvm have been upgraded to 3.4 release. 266 26720140306: 268 If a Makefile in a tests/ directory was auto-generating a Kyuafile 269 instead of providing an explicit one, this would prevent such 270 Makefile from providing its own Kyuafile in the future during 271 NO_CLEAN builds. This has been fixed in the Makefiles but manual 272 intervention is needed to clean an objdir if you use NO_CLEAN: 273 # find /usr/obj -name Kyuafile | xargs rm -f 274 27520140303: 276 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 277 capability mode support. Please note that enabling the feature in 278 kernel is still highly recommended. 279 28020140227: 281 OpenSSH is now built with sandbox support, and will use sandbox as 282 the default privilege separation method. This requires Capsicum 283 capability mode support in kernel. 284 28520140216: 286 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 287 been deprecated and will not be part of FreeBSD 11.0 and later 288 releases. If you use this driver, please consider switching to 289 the nfe(4) driver instead. 290 29120140120: 292 10.0-RELEASE. 293 29420131216: 295 The behavior of gss_pseudo_random() for the krb5 mechanism 296 has changed, for applications requesting a longer random string 297 than produced by the underlying enctype's pseudo-random() function. 298 In particular, the random string produced from a session key of 299 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 300 be different at the 17th octet and later, after this change. 301 The counter used in the PRF+ construction is now encoded as a 302 big-endian integer in accordance with RFC 4402. 303 __FreeBSD_version is bumped to 1000701. 304 30520131108: 306 The WITHOUT_ATF build knob has been removed and its functionality 307 has been subsumed into the more generic WITHOUT_TESTS. If you were 308 using the former to disable the build of the ATF libraries, you 309 should change your settings to use the latter. 310 31120131031: 312 The default version of mtree is nmtree which is obtained from 313 NetBSD. The output is generally the same, but may vary 314 slightly. If you found you need identical output adding 315 "-F freebsd9" to the command line should do the trick. For the 316 time being, the old mtree is available as fmtree. 317 31820131014: 319 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 320 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 321 1.1.4_8 and verify bsdyml not linked in, before running "make 322 delete-old-libs": 323 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 324 or 325 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 326 32720131010: 328 The rc.d/jail script has been updated to support jail(8) 329 configuration file. The "jail_<jname>_*" rc.conf(5) variables 330 for per-jail configuration are automatically converted to 331 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 332 This is transparently backward compatible. See below about some 333 incompatibilities and rc.conf(5) manual page for more details. 334 335 These variables are now deprecated in favor of jail(8) configuration 336 file. One can use "rc.d/jail config <jname>" command to generate 337 a jail(8) configuration file in /var/run/jail.<jname>.conf without 338 running the jail(8) utility. The default pathname of the 339 configuration file is /etc/jail.conf and can be specified by 340 using $jail_conf or $jail_<jname>_conf variables. 341 342 Please note that jail_devfs_ruleset accepts an integer at 343 this moment. Please consider to rewrite the ruleset name 344 with an integer. 345 34620130930: 347 BIND has been removed from the base system. If all you need 348 is a local resolver, simply enable and start the local_unbound 349 service instead. Otherwise, several versions of BIND are 350 available in the ports tree. The dns/bind99 port is one example. 351 352 With this change, nslookup(1) and dig(1) are no longer in the base 353 system. Users should instead use host(1) and drill(1) which are 354 in the base system. Alternatively, nslookup and dig can 355 be obtained by installing the dns/bind-tools port. 356 35720130916: 358 With the addition of unbound(8), a new unbound user is now 359 required during installworld. "mergemaster -p" can be used to 360 add the user prior to installworld, as documented in the handbook. 361 36220130911: 363 OpenSSH is now built with DNSSEC support, and will by default 364 silently trust signed SSHFP records. This can be controlled with 365 the VerifyHostKeyDNS client configuration setting. DNSSEC support 366 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 367 36820130906: 369 The GNU Compiler Collection and C++ standard library (libstdc++) 370 are no longer built by default on platforms where clang is the system 371 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 372 options in src.conf. 373 37420130905: 375 The PROCDESC kernel option is now part of the GENERIC kernel 376 configuration and is required for the rwhod(8) to work. 377 If you are using custom kernel configuration, you should include 378 'options PROCDESC'. 379 38020130905: 381 The API and ABI related to the Capsicum framework was modified 382 in backward incompatible way. The userland libraries and programs 383 have to be recompiled to work with the new kernel. This includes the 384 following libraries and programs, but the whole buildworld is 385 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 386 kdump, procstat, rwho, rwhod, uniq. 387 38820130903: 389 AES-NI intrinsic support has been added to gcc. The AES-NI module 390 has been updated to use this support. A new gcc is required to build 391 the aesni module on both i386 and amd64. 392 39320130821: 394 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 395 Thus "device padlock_rng" and "device rdrand_rng" should be 396 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 397 39820130813: 399 WITH_ICONV has been split into two feature sets. WITH_ICONV now 400 enables just the iconv* functionality and is now on by default. 401 WITH_LIBICONV_COMPAT enables the libiconv api and link time 402 compatability. Set WITHOUT_ICONV to build the old way. 403 If you have been using WITH_ICONV before, you will very likely 404 need to turn on WITH_LIBICONV_COMPAT. 405 40620130806: 407 INVARIANTS option now enables DEBUG for code with OpenSolaris and 408 Illumos origin, including ZFS. If you have INVARIANTS in your 409 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 410 explicitly. 411 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 412 locks if WITNESS option was set. Because that generated a lot of 413 witness(9) reports and all of them were believed to be false 414 positives, this is no longer done. New option OPENSOLARIS_WITNESS 415 can be used to achieve the previous behavior. 416 41720130806: 418 Timer values in IPv6 data structures now use time_uptime instead 419 of time_second. Although this is not a user-visible functional 420 change, userland utilities which directly use them---ndp(8), 421 rtadvd(8), and rtsold(8) in the base system---need to be updated 422 to r253970 or later. 423 42420130802: 425 find -delete can now delete the pathnames given as arguments, 426 instead of only files found below them or if the pathname did 427 not contain any slashes. Formerly, the following error message 428 would result: 429 430 find: -delete: <path>: relative path potentially not safe 431 432 Deleting the pathnames given as arguments can be prevented 433 without error messages using -mindepth 1 or by changing 434 directory and passing "." as argument to find. This works in the 435 old as well as the new version of find. 436 43720130726: 438 Behavior of devfs rules path matching has been changed. 439 Pattern is now always matched against fully qualified devfs 440 path and slash characters must be explicitly matched by 441 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 442 subdirectories must be reviewed. 443 44420130716: 445 The default ARM ABI has changed to the ARM EABI. The old ABI is 446 incompatible with the ARM EABI and all programs and modules will 447 need to be rebuilt to work with a new kernel. 448 449 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 450 451 NOTE: Support for the old ABI will be removed in the future and 452 users are advised to upgrade. 453 45420130709: 455 pkg_install has been disconnected from the build if you really need it 456 you should add WITH_PKGTOOLS in your src.conf(5). 457 45820130709: 459 Most of network statistics structures were changed to be able 460 keep 64-bits counters. Thus all tools, that work with networking 461 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 462 46320130629: 464 Fix targets that run multiple make's to use && rather than ; 465 so that subsequent steps depend on success of previous. 466 467 NOTE: if building 'universe' with -j* on stable/8 or stable/9 468 it would be better to start the build using bmake, to avoid 469 overloading the machine. 470 47120130618: 472 Fix a bug that allowed a tracing process (e.g. gdb) to write 473 to a memory-mapped file in the traced process's address space 474 even if neither the traced process nor the tracing process had 475 write access to that file. 476 47720130615: 478 CVS has been removed from the base system. An exact copy 479 of the code is available from the devel/cvs port. 480 48120130613: 482 Some people report the following error after the switch to bmake: 483 484 make: illegal option -- J 485 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 486 ... 487 *** [buildworld] Error code 2 488 489 this likely due to an old instance of make in 490 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 491 which src/Makefile will use that blindly, if it exists, so if 492 you see the above error: 493 494 rm -rf `make -V MAKEPATH` 495 496 should resolve it. 497 49820130516: 499 Use bmake by default. 500 Whereas before one could choose to build with bmake via 501 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 502 make. The goal is to remove these knobs for 10-RELEASE. 503 504 It is worth noting that bmake (like gmake) treats the command 505 line as the unit of failure, rather than statements within the 506 command line. Thus '(cd some/where && dosomething)' is safer 507 than 'cd some/where; dosomething'. The '()' allows consistent 508 behavior in parallel build. 509 51020130429: 511 Fix a bug that allows NFS clients to issue READDIR on files. 512 51320130426: 514 The WITHOUT_IDEA option has been removed because 515 the IDEA patent expired. 516 51720130426: 518 The sysctl which controls TRIM support under ZFS has been renamed 519 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 520 enabled by default. 521 52220130425: 523 The mergemaster command now uses the default MAKEOBJDIRPREFIX 524 rather than creating it's own in the temporary directory in 525 order allow access to bootstrapped versions of tools such as 526 install and mtree. When upgrading from version of FreeBSD where 527 the install command does not support -l, you will need to 528 install a new mergemaster command if mergemaster -p is required. 529 This can be accomplished with the command (cd src/usr.sbin/mergemaster 530 && make install). 531 53220130404: 533 Legacy ATA stack, disabled and replaced by new CAM-based one since 534 FreeBSD 9.0, completely removed from the sources. Kernel modules 535 atadisk and atapi*, user-level tools atacontrol and burncd are 536 removed. Kernel option `options ATA_CAM` is now permanently enabled 537 and removed. 538 53920130319: 540 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 541 and socketpair(2). Software, in particular Kerberos, may 542 automatically detect and use these during building. The resulting 543 binaries will not work on older kernels. 544 54520130308: 546 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 547 information, see the respective 20130304 entry). 548 54920130304: 550 Recent commits to callout(9) changed the size of struct callout, 551 so the KBI is probably heavily disturbed. Also, some functions 552 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 553 by macros. Every kernel module using it won't load, so rebuild 554 is requested. 555 556 The ctl device has been re-enabled in GENERIC for i386 and amd64, 557 but does not initialize by default (because of the new CTL_DISABLE 558 option) to save memory. To re-enable it, remove the CTL_DISABLE 559 option from the kernel config file or set kern.cam.ctl.disable=0 560 in /boot/loader.conf. 561 56220130301: 563 The ctl device has been disabled in GENERIC for i386 and amd64. 564 This was done due to the extra memory being allocated at system 565 initialisation time by the ctl driver which was only used if 566 a CAM target device was created. This makes a FreeBSD system 567 unusable on 128MB or less of RAM. 568 56920130208: 570 A new compression method (lz4) has been merged to -HEAD. Please 571 refer to zpool-features(7) for more information. 572 573 Please refer to the "ZFS notes" section of this file for information 574 on upgrading boot ZFS pools. 575 57620130129: 577 A BSD-licensed patch(1) variant has been added and is installed 578 as bsdpatch, being the GNU version the default patch. 579 To inverse the logic and use the BSD-licensed one as default, 580 while having the GNU version installed as gnupatch, rebuild 581 and install world with the WITH_BSD_PATCH knob set. 582 58320130121: 584 Due to the use of the new -l option to install(1) during build 585 and install, you must take care not to directly set the INSTALL 586 make variable in your /etc/make.conf, /etc/src.conf, or on the 587 command line. If you wish to use the -C flag for all installs 588 you may be able to add INSTALL+=-C to /etc/make.conf or 589 /etc/src.conf. 590 59120130118: 592 The install(1) option -M has changed meaning and now takes an 593 argument that is a file or path to append logs to. In the 594 unlikely event that -M was the last option on the command line 595 and the command line contained at least two files and a target 596 directory the first file will have logs appended to it. The -M 597 option served little practical purpose in the last decade so its 598 use is expected to be extremely rare. 599 60020121223: 601 After switching to Clang as the default compiler some users of ZFS 602 on i386 systems started to experience stack overflow kernel panics. 603 Please consider using 'options KSTACK_PAGES=4' in such configurations. 604 60520121222: 606 GEOM_LABEL now mangles label names read from file system metadata. 607 Mangling affect labels containing spaces, non-printable characters, 608 '%' or '"'. Device names in /etc/fstab and other places may need to 609 be updated. 610 61120121217: 612 By default, only the 10 most recent kernel dumps will be saved. To 613 restore the previous behaviour (no limit on the number of kernel dumps 614 stored in the dump directory) add the following line to /etc/rc.conf: 615 616 savecore_flags="" 617 61820121201: 619 With the addition of auditdistd(8), a new auditdistd user is now 620 required during installworld. "mergemaster -p" can be used to 621 add the user prior to installworld, as documented in the handbook. 622 62320121117: 624 The sin6_scope_id member variable in struct sockaddr_in6 is now 625 filled by the kernel before passing the structure to the userland via 626 sysctl or routing socket. This means the KAME-specific embedded scope 627 id in sin6_addr.s6_addr[2] is always cleared in userland application. 628 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 629 __FreeBSD_version is bumped to 1000025. 630 63120121105: 632 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 633 This means that the world and kernel will be compiled with clang 634 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 635 and /usr/bin/cpp. To disable this behavior and revert to building 636 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 637 of current may need to bootstrap WITHOUT_CLANG first if the clang 638 build fails (its compatibility window doesn't extend to the 9 stable 639 branch point). 640 64120121102: 642 The IPFIREWALL_FORWARD kernel option has been removed. Its 643 functionality now turned on by default. 644 64520121023: 646 The ZERO_COPY_SOCKET kernel option has been removed and 647 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 648 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 649 mechanism which is not safe and may result in kernel crashes. 650 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 651 driver supports disposeable external page sized mbuf storage. 652 Proper replacements for both zero-copy mechanisms are under 653 consideration and will eventually lead to complete removal 654 of the two kernel options. 655 65620121023: 657 The IPv4 network stack has been converted to network byte 658 order. The following modules need to be recompiled together 659 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 660 pf(4), ipfw(4), ng_ipfw(4), stf(4). 661 66220121022: 663 Support for non-MPSAFE filesystems was removed from VFS. The 664 VFS_VERSION was bumped, all filesystem modules shall be 665 recompiled. 666 66720121018: 668 All the non-MPSAFE filesystems have been disconnected from 669 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 670 portalfs, smbfs, xfs. 671 67220121016: 673 The interface cloning API and ABI has changed. The following 674 modules need to be recompiled together with kernel: 675 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 676 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 677 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 678 67920121015: 680 The sdhci driver was split in two parts: sdhci (generic SD Host 681 Controller logic) and sdhci_pci (actual hardware driver). 682 No kernel config modifications are required, but if you 683 load sdhc as a module you must switch to sdhci_pci instead. 684 68520121014: 686 Import the FUSE kernel and userland support into base system. 687 68820121013: 689 The GNU sort(1) program has been removed since the BSD-licensed 690 sort(1) has been the default for quite some time and no serious 691 problems have been reported. The corresponding WITH_GNU_SORT 692 knob has also gone. 693 69420121006: 695 The pfil(9) API/ABI for AF_INET family has been changed. Packet 696 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 697 with new kernel. 698 69920121001: 700 The net80211(4) ABI has been changed to allow for improved driver 701 PS-POLL and power-save support. All wireless drivers need to be 702 recompiled to work with the new kernel. 703 70420120913: 705 The random(4) support for the VIA hardware random number 706 generator (`PADLOCK') is no longer enabled unconditionally. 707 Add the padlock_rng device in the custom kernel config if 708 needed. The GENERIC kernels on i386 and amd64 do include the 709 device, so the change only affects the custom kernel 710 configurations. 711 71220120908: 713 The pf(4) packet filter ABI has been changed. pfctl(8) and 714 snmp_pf module need to be recompiled to work with new kernel. 715 71620120828: 717 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 718 to -HEAD. Pools that have empty_bpobj in active state can not be 719 imported read-write with ZFS implementations that do not support 720 this feature. For more information read the zpool-features(5) 721 manual page. 722 72320120727: 724 The sparc64 ZFS loader has been changed to no longer try to auto- 725 detect ZFS providers based on diskN aliases but now requires these 726 to be explicitly listed in the OFW boot-device environment variable. 727 72820120712: 729 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 730 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 731 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 732 73320120712: 734 The following sysctls and tunables have been renamed for consistency 735 with other variables: 736 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 737 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 738 73920120628: 740 The sort utility has been replaced with BSD sort. For now, GNU sort 741 is also available as "gnusort" or the default can be set back to 742 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 743 installed as "bsdsort". 744 74520120611: 746 A new version of ZFS (pool version 5000) has been merged to -HEAD. 747 Starting with this version the old system of ZFS pool versioning 748 is superseded by "feature flags". This concept enables forward 749 compatibility against certain future changes in functionality of ZFS 750 pools. The first read-only compatible "feature flag" for ZFS pools 751 is named "com.delphix:async_destroy". For more information 752 read the new zpool-features(5) manual page. 753 Please refer to the "ZFS notes" section of this file for information 754 on upgrading boot ZFS pools. 755 75620120417: 757 The malloc(3) implementation embedded in libc now uses sources imported 758 as contrib/jemalloc. The most disruptive API change is to 759 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 760 delete it prior to installworld, and optionally re-create it using the 761 new format after rebooting. See malloc.conf(5) for details 762 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 763 NAMESPACE section). 764 76520120328: 766 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 767 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 768 now spelled mips. This is to aid compatibility with third-party 769 software that expects this naming scheme in uname(3). Little-endian 770 settings are unchanged. If you are updating a big-endian mips64 machine 771 from before this change, you may need to set MACHINE_ARCH=mips64 in 772 your environment before the new build system will recognize your machine. 773 77420120306: 775 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 776 platforms. 777 77820120229: 779 Now unix domain sockets behave "as expected" on nullfs(5). Previously 780 nullfs(5) did not pass through all behaviours to the underlying layer, 781 as a result if we bound to a socket on the lower layer we could connect 782 only to the lower path; if we bound to the upper layer we could connect 783 only to the upper path. The new behavior is one can connect to both the 784 lower and the upper paths regardless what layer path one binds to. 785 78620120211: 787 The getifaddrs upgrade path broken with 20111215 has been restored. 788 If you have upgraded in between 20111215 and 20120209 you need to 789 recompile libc again with your kernel. You still need to recompile 790 world to be able to configure CARP but this restriction already 791 comes from 20111215. 792 79320120114: 794 The set_rcvar() function has been removed from /etc/rc.subr. All 795 base and ports rc.d scripts have been updated, so if you have a 796 port installed with a script in /usr/local/etc/rc.d you can either 797 hand-edit the rcvar= line, or reinstall the port. 798 799 An easy way to handle the mass-update of /etc/rc.d: 800 rm /etc/rc.d/* && mergemaster -i 801 80220120109: 803 panic(9) now stops other CPUs in the SMP systems, disables interrupts 804 on the current CPU and prevents other threads from running. 805 This behavior can be reverted using the kern.stop_scheduler_on_panic 806 tunable/sysctl. 807 The new behavior can be incompatible with kern.sync_on_panic. 808 80920111215: 810 The carp(4) facility has been changed significantly. Configuration 811 of the CARP protocol via ifconfig(8) has changed, as well as format 812 of CARP events submitted to devd(8) has changed. See manual pages 813 for more information. The arpbalance feature of carp(4) is currently 814 not supported anymore. 815 816 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 817 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 818 need to be recompiled. 819 82020111122: 821 The acpi_wmi(4) status device /dev/wmistat has been renamed to 822 /dev/wmistat0. 823 82420111108: 825 The option VFS_ALLOW_NONMPSAFE option has been added in order to 826 explicitely support non-MPSAFE filesystems. 827 It is on by default for all supported platform at this present 828 time. 829 83020111101: 831 The broken amd(4) driver has been replaced with esp(4) in the amd64, 832 i386 and pc98 GENERIC kernel configuration files. 833 83420110930: 835 sysinstall has been removed 836 83720110923: 838 The stable/9 branch created in subversion. This corresponds to the 839 RELENG_9 branch in CVS. 840 84120110913: 842 This commit modifies vfs_register() so that it uses a hash 843 calculation to set vfc_typenum, which is enabled by default. 844 The first time a system is booted after this change, the 845 vfc_typenum values will change for all file systems. The 846 main effect of this is a change to the NFS server file handles 847 for file systems that use vfc_typenum in their fsid, such as ZFS. 848 It will, however, prevent vfc_typenum from changing when file 849 systems are loaded in a different order for subsequent reboots. 850 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 851 until you are ready to remount all NFS clients after a reboot. 852 85320110828: 854 Bump the shared library version numbers for libraries that 855 do not use symbol versioning, have changed the ABI compared 856 to stable/8 and which shared library version was not bumped. 857 Done as part of 9.0-RELEASE cycle. 858 85920110815: 860 During the merge of Capsicum features, the fget(9) KPI was modified. 861 This may require the rebuilding of out-of-tree device drivers -- 862 issues have been reported specifically with the nVidia device driver. 863 __FreeBSD_version is bumped to 900041. 864 865 Also, there is a period between 20110811 and 20110814 where the 866 special devices /dev/{stdin,stdout,stderr} did not work correctly. 867 Building world from a kernel during that window may not work. 868 86920110628: 870 The packet filter (pf) code has been updated to OpenBSD 4.5. 871 You need to update userland tools to be in sync with kernel. 872 This update breaks backward compatibility with earlier pfsync(4) 873 versions. Care must be taken when updating redundant firewall setups. 874 87520110608: 876 The following sysctls and tunables are retired on x86 platforms: 877 machdep.hlt_cpus 878 machdep.hlt_logical_cpus 879 The following sysctl is retired: 880 machdep.hyperthreading_allowed 881 The sysctls were supposed to provide a way to dynamically offline and 882 online selected CPUs on x86 platforms, but the implementation has not 883 been reliable especially with SCHED_ULE scheduler. 884 machdep.hyperthreading_allowed tunable is still available to ignore 885 hyperthreading CPUs at OS level. 886 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 887 where X is an APIC ID of a CPU. Be advised, though, that disabling 888 CPUs in non-uniform fashion will result in non-uniform topology and 889 may lead to sub-optimal system performance with SCHED_ULE, which is 890 a default scheduler. 891 89220110607: 893 cpumask_t type is retired and cpuset_t is used in order to describe 894 a mask of CPUs. 895 89620110531: 897 Changes to ifconfig(8) for dynamic address family detection mandate 898 that you are running a kernel of 20110525 or later. Make sure to 899 follow the update procedure to boot a new kernel before installing 900 world. 901 90220110513: 903 Support for sun4v architecture is officially dropped 904 90520110503: 906 Several KPI breaking changes have been committed to the mii(4) layer, 907 the PHY drivers and consequently some Ethernet drivers using mii(4). 908 This means that miibus.ko and the modules of the affected Ethernet 909 drivers need to be recompiled. 910 911 Note to kernel developers: Given that the OUI bit reversion problem 912 was fixed as part of these changes all mii(4) commits related to OUIs, 913 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 914 handling, no longer can be merged verbatim to stable/8 and previous 915 branches. 916 91720110430: 918 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 919 into their kernel configurations along with 'device pci'. 920 92120110427: 922 The default NFS client is now the new NFS client, so fstype "newnfs" 923 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 924 Although mounts via fstype "nfs" will usually work without userland 925 changes, it is recommended that the mount(8) and mount_nfs(8) 926 commands be rebuilt from sources and that a link to mount_nfs called 927 mount_oldnfs be created. The new client is compiled into the 928 kernel with "options NFSCL" and this is needed for diskless root 929 file systems. The GENERIC kernel configs have been changed to use 930 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 931 To use the regular/old client, you can "mount -t oldnfs ...". For 932 a diskless root file system, you must also include a line like: 933 934 vfs.root.mountfrom="oldnfs:" 935 936 in the boot/loader.conf on the root fs on the NFS server to make 937 a diskless root fs use the old client. 938 93920110424: 940 The GENERIC kernels for all architectures now default to the new 941 CAM-based ATA stack. It means that all legacy ATA drivers were 942 removed and replaced by respective CAM drivers. If you are using 943 ATA device names in /etc/fstab or other places, make sure to update 944 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 945 where 'Y's are the sequential numbers starting from zero for each type 946 in order of detection, unless configured otherwise with tunables, 947 see cam(4)). There will be symbolic links created in /dev/ to map 948 old adX devices to the respective adaY. They should provide basic 949 compatibility for file systems mounting in most cases, but they do 950 not support old user-level APIs and do not have respective providers 951 in GEOM. Consider using updated management tools with new device names. 952 953 It is possible to load devices ahci, ata, siis and mvs as modules, 954 but option ATA_CAM should remain in kernel configuration to make ata 955 module work as CAM driver supporting legacy ATA controllers. Device ata 956 still can be used in modular fashion (atacore + ...). Modules atadisk 957 and atapi* are not used and won't affect operation in ATA_CAM mode. 958 Note that to use CAM-based ATA kernel should include CAM devices 959 scbus, pass, da (or explicitly ada), cd and optionally others. All of 960 them are parts of the cam module. 961 962 ataraid(4) functionality is now supported by the RAID GEOM class. 963 To use it you can load geom_raid kernel module and use graid(8) tool 964 for management. Instead of /dev/arX device names, use /dev/raid/rX. 965 966 No kernel config options or code have been removed, so if a problem 967 arises, please report it and optionally revert to the old ATA stack. 968 In order to do it you can remove from the kernel config: 969 options ATA_CAM 970 device ahci 971 device mvs 972 device siis 973 , and instead add back: 974 device atadisk # ATA disk drives 975 device ataraid # ATA RAID drives 976 device atapicd # ATAPI CDROM drives 977 device atapifd # ATAPI floppy drives 978 device atapist # ATAPI tape drives 979 98020110423: 981 The default NFS server has been changed to the new server, which 982 was referred to as the experimental server. If you need to switch 983 back to the old NFS server, you must now put the "-o" option on 984 both the mountd and nfsd commands. This can be done using the 985 mountd_flags and nfs_server_flags rc.conf variables until an 986 update to the rc scripts is committed, which is coming soon. 987 98820110418: 989 The GNU Objective-C runtime library (libobjc), and other Objective-C 990 related components have been removed from the base system. If you 991 require an Objective-C library, please use one of the available ports. 992 99320110331: 994 ath(4) has been split into bus- and device- modules. if_ath contains 995 the HAL, the TX rate control and the network device code. if_ath_pci 996 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 997 contains the AHB glue. Users need to load both if_ath_pci and if_ath 998 in order to use ath on everything else. 999 1000 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1001 need to load if_ath and if_ath_pci for ath(4) operation. 1002 100320110314: 1004 As part of the replacement of sysinstall, the process of building 1005 release media has changed significantly. For details, please re-read 1006 release(7), which has been updated to reflect the new build process. 1007 100820110218: 1009 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1010 is the last available version under GPLv2. It brings a number of new 1011 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1012 4.1 and SSE 4.2), better support for powerpc64, a number of new 1013 directives, and lots of other small improvements. See the ChangeLog 1014 file in contrib/binutils for the full details. 1015 101620110218: 1017 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1018 compliant, and will now use half of hash for authentication. 1019 This will break interoperability with all stacks (including all 1020 actual FreeBSD versions) who implement 1021 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1022 authentication). 1023 The only workaround with such peers is to use another HMAC 1024 algorithm for IPsec ("phase 2") authentication. 1025 102620110207: 1027 Remove the uio_yield prototype and symbol. This function has 1028 been misnamed since it was introduced and should not be 1029 globally exposed with this name. The equivalent functionality 1030 is now available using kern_yield(curthread->td_user_pri). 1031 The function remains undocumented. 1032 103320110112: 1034 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1035 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1036 for scalar sysctls is defined but disabled. Code that needs 1037 UQUAD to pass the type checking that must compile on older 1038 systems where the define is not present can check against 1039 __FreeBSD_version >= 900030. 1040 1041 The system dialog(1) has been replaced with a new version previously 1042 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1043 with the previous version, but the libdialog associated with it has 1044 a largely incompatible API. As such, the original version of libdialog 1045 will be kept temporarily as libodialog, until its base system consumers 1046 are replaced or updated. Bump __FreeBSD_version to 900030. 1047 104820110103: 1049 If you are trying to run make universe on a -stable system, and you get 1050 the following warning: 1051 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1052 unknown. config(8) likely too old." 1053 or something similar to it, then you must upgrade your -stable system 1054 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1055 stable/8) or build the config from the latest stable/8 branch and 1056 install it on your system. 1057 1058 Prior to this date, building a current universe on 8-stable system from 1059 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1060 error in the first kernel build phase. A new config on those old 1061 systems will fix that problem for older versions of -current. 1062 106320101228: 1064 The TCP stack has been modified to allow Khelp modules to interact with 1065 it via helper hook points and store per-connection data in the TCP 1066 control block. Bump __FreeBSD_version to 900029. User space tools that 1067 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1068 be recompiled. 1069 107020101114: 1071 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1072 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1073 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1074 to take advantage of it instead of using custom implementations. This 1075 means that these drivers now no longer unconditionally advertise 1076 support for flow control but only do so if flow control is a selected 1077 media option. This was implemented in the generic support that way in 1078 order to allow flow control to be switched on and off via ifconfig(8) 1079 with the PHY specific default to typically off in order to protect 1080 from unwanted effects. Consequently, if you used flow control with 1081 one of the above mentioned drivers you now need to explicitly enable 1082 it, for example via: 1083 ifconfig bge0 media auto mediaopt flowcontrol 1084 1085 Along with the above mentioned changes generic support for setting 1086 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1087 e1000phy(4) as well as ip1000phy(4) have been converted to take 1088 advantage of it. This means that these drivers now no longer take the 1089 link0 parameter for selecting master mode but the master media option 1090 has to be used instead, for example like in the following: 1091 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1092 1093 Selection of master mode now is also available with all other PHY 1094 drivers supporting 1000baseT. 1095 109620101111: 1097 The TCP stack has received a significant update to add support for 1098 modularised congestion control and generally improve the clarity of 1099 congestion control decisions. Bump __FreeBSD_version to 900025. User 1100 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1101 sockstat) need to be recompiled. 1102 110320101002: 1104 The man(1) utility has been replaced by a new version that no longer 1105 uses /etc/manpath.config. Please consult man.conf(5) for how to 1106 migrate local entries to the new format. 1107 110820100928: 1109 The copyright strings printed by login(1) and sshd(8) at the time of a 1110 new connection have been removed to follow other operating systems and 1111 upstream sshd. 1112 111320100915: 1114 A workaround for a fixed ld bug has been removed in kernel code, 1115 so make sure that your system ld is built from sources after 1116 revision 210245 from 2010-07-19 (r211583 if building head kernel 1117 on stable/8, r211584 for stable/7; both from 2010-08-21). 1118 A symptom of incorrect ld version is different addresses for 1119 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1120 112120100913: 1122 The $ipv6_prefer variable in rc.conf(5) has been split into 1123 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1124 1125 The $ip6addrctl_policy is a variable to choose a pre-defined 1126 address selection policy set by ip6addrctl(8). A value 1127 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1128 default is "AUTO". 1129 1130 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1131 flag (see an entry of 20090926) is set on an interface with no 1132 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1133 security reason. If you want IPv6 link-local address on all 1134 interfaces by default, set this to "YES". 1135 1136 The old ipv6_prefer="YES" is equivalent to 1137 ipv6_activate_all_interfaces="YES" and 1138 ip6addrctl_policy="ipv6_prefer". 1139 114020100913: 1141 DTrace has grown support for userland tracing. Due to this, DTrace is 1142 now i386 and amd64 only. 1143 dtruss(1) is now installed by default on those systems and a new 1144 kernel module is needed for userland tracing: fasttrap. 1145 No changes to your kernel config file are necessary to enable 1146 userland tracing, but you might consider adding 'STRIP=' and 1147 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1148 to have informative userland stack traces in DTrace (ustack). 1149 115020100725: 1151 The acpi_aiboost(4) driver has been removed in favor of the new 1152 aibs(4) driver. You should update your kernel configuration file. 1153 115420100722: 1155 BSD grep has been imported to the base system and it is built by 1156 default. It is completely BSD licensed, highly GNU-compatible, uses 1157 less memory than its GNU counterpart and has a small codebase. 1158 However, it is slower than its GNU counterpart, which is mostly 1159 noticeable for larger searches, for smaller ones it is measurable 1160 but not significant. The reason is complex, the most important factor 1161 is that we lack a modern and efficient regex library and GNU 1162 overcomes this by optimizing the searches internally. Future work 1163 on improving the regex performance is planned, for the meantime, 1164 users that need better performance, can build GNU grep instead by 1165 setting the WITH_GNU_GREP knob. 1166 116720100713: 1168 Due to the import of powerpc64 support, all existing powerpc kernel 1169 configuration files must be updated with a machine directive like this: 1170 machine powerpc powerpc 1171 1172 In addition, an updated config(8) is required to build powerpc kernels 1173 after this change. 1174 117520100713: 1176 A new version of ZFS (version 15) has been merged to -HEAD. 1177 This version uses a python library for the following subcommands: 1178 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1179 For full functionality of these commands the following port must 1180 be installed: sysutils/py-zfs 1181 118220100429: 1183 'vm_page's are now hashed by physical address to an array of mutexes. 1184 Currently this is only used to serialize access to hold_count. Over 1185 time the page queue mutex will be peeled away. This changes the size 1186 of pmap on every architecture. And requires all callers of vm_page_hold 1187 and vm_page_unhold to be updated. 1188 118920100402: 1190 WITH_CTF can now be specified in src.conf (not recommended, there 1191 are some problems with static executables), make.conf (would also 1192 affect ports which do not use GNU make and do not override the 1193 compile targets) or in the kernel config (via "makeoptions 1194 WITH_CTF=yes"). 1195 When WITH_CTF was specified there before this was silently ignored, 1196 so make sure that WITH_CTF is not used in places which could lead 1197 to unwanted behavior. 1198 119920100311: 1200 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1201 to allow 32-bit compatibility on non-x86 platforms. All kernel 1202 configurations on amd64 and ia64 platforms using these options must 1203 be modified accordingly. 1204 120520100113: 1206 The utmp user accounting database has been replaced with utmpx, 1207 the user accounting interface standardized by POSIX. 1208 Unfortunately the semantics of utmp and utmpx don't match, 1209 making it practically impossible to support both interfaces. 1210 The user accounting database is used by tools like finger(1), 1211 last(1), talk(1), w(1) and ac(8). 1212 1213 All applications in the base system use utmpx. This means only 1214 local binaries (e.g. from the ports tree) may still use these 1215 utmp database files. These applications must be rebuilt to make 1216 use of utmpx. 1217 1218 After the system has been upgraded, it is safe to remove the old 1219 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1220 assuming their contents is of no importance anymore. Old wtmp 1221 databases can only be used by last(1) and ac(8) after they have 1222 been converted to the new format using wtmpcvt(1). 1223 122420100108: 1225 Introduce the kernel thread "deadlock resolver" (which can be enabled 1226 via the DEADLKRES option, see NOTES for more details) and the 1227 sleepq_type() function for sleepqueues. 1228 122920091202: 1230 The rc.firewall and rc.firewall6 were unified, and 1231 rc.firewall6 and rc.d/ip6fw were removed. 1232 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1233 variables are obsoleted. Instead, the following new rc 1234 variables are added to rc.d/ipfw: 1235 1236 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1237 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1238 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1239 1240 The meanings correspond to the relevant IPv4 variables. 1241 124220091125: 1243 8.0-RELEASE. 1244 124520091113: 1246 The default terminal emulation for syscons(4) has been changed 1247 from cons25 to xterm on all platforms except pc98. This means 1248 that the /etc/ttys file needs to be updated to ensure correct 1249 operation of applications on the console. 1250 1251 The terminal emulation style can be toggled per window by using 1252 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1253 options can be used to change the compile-time default back to 1254 cons25. 1255 1256 To prevent graphical artifacts, make sure the TERM environment 1257 variable is set to match the terminal emulation that is being 1258 performed by syscons(4). 1259 126020091109: 1261 The layout of the structure ieee80211req_scan_result has changed. 1262 Applications that require wireless scan results (e.g. ifconfig(8)) 1263 from net80211 need to be recompiled. 1264 1265 Applications such as wpa_supplicant(8) may require a full world 1266 build without using NO_CLEAN in order to get synchronized with the 1267 new structure. 1268 126920091025: 1270 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1271 There's one kernel module for each firmware. Adding "device iwnfw" 1272 to the kernel configuration file means including all three firmware 1273 images inside the kernel. If you want to include just the one for 1274 your wireless card, use the devices iwn4965fw, iwn5000fw or 1275 iwn5150fw. 1276 127720090926: 1278 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1279 into rc.d/netif. The changes are the following: 1280 1281 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1282 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1283 Note that both variables need the "inet6" keyword at the head. 1284 1285 Do not set $ipv6_network_interfaces manually if you do not 1286 understand what you are doing. It is not needed in most cases. 1287 1288 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1289 they are obsolete. 1290 1291 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1292 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1293 1294 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1295 all configured interfaces have "inet6 accept_rtadv" in the 1296 $ifconfig_IF_ipv6. These are for backward compatibility. 1297 1298 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1299 functionality of interfaces with no corresponding 1300 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1301 and the default address selection policy of ip6addrctl(8) 1302 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1303 Note that if you want to configure IPv6 functionality on the 1304 disabled interfaces after boot, first you need to clear the flag by 1305 using ifconfig(8) like: 1306 1307 ifconfig em0 inet6 -ifdisabled 1308 1309 If YES, the default address selection policy is set as 1310 IPv6-preferred. 1311 1312 The default value of $ipv6_prefer is NO. 1313 1314 4. If your system need to receive Router Advertisement messages, 1315 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1316 scripts automatically invoke rtsol(8) when the interface becomes 1317 UP. The Router Advertisement messages are used for SLAAC 1318 (State-Less Address AutoConfiguration). 1319 132020090922: 1321 802.11s D3.03 support was committed. This is incompatible with the 1322 previous code, which was based on D3.0. 1323 132420090912: 1325 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1326 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1327 control whether accepting Router Advertisement messages or not. 1328 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1329 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1330 The ifconfig(8) utility now supports these flags. 1331 133220090910: 1333 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1334 mount(8) and -a option for df(1) to see them. 1335 133620090825: 1337 The old tunable hw.bus.devctl_disable has been superseded by 1338 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1339 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1340 is 1000. 1341 134220090813: 1343 Remove the option STOP_NMI. The default action is now to use NMI only 1344 for KDB via the newly introduced function stop_cpus_hard() and 1345 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1346 134720090803: 1348 The stable/8 branch created in subversion. This corresponds to the 1349 RELENG_8 branch in CVS. 1350 135120090719: 1352 Bump the shared library version numbers for all libraries that do not 1353 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1354 __FreeBSD_version to 800105. 1355 135620090714: 1357 Due to changes in the implementation of virtual network stack support, 1358 all network-related kernel modules must be recompiled. As this change 1359 breaks the ABI, bump __FreeBSD_version to 800104. 1360 136120090713: 1362 The TOE interface to the TCP syncache has been modified to remove 1363 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1364 The cxgb driver is the only TOE consumer affected by this change, and 1365 needs to be recompiled along with the kernel. As this change breaks 1366 the ABI, bump __FreeBSD_version to 800103. 1367 136820090712: 1369 Padding has been added to struct tcpcb, sackhint and tcpstat in 1370 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1371 maintaining the ABI. However, this change breaks the ABI, so bump 1372 __FreeBSD_version to 800102. User space tools that rely on the size of 1373 any of these structs (e.g. sockstat) need to be recompiled. 1374 137520090630: 1376 The NFS_LEGACYRPC option has been removed along with the old kernel 1377 RPC implementation that this option selected. Kernel configurations 1378 may need to be adjusted. 1379 138020090629: 1381 The network interface device nodes at /dev/net/<interface> have been 1382 removed. All ioctl operations can be performed the normal way using 1383 routing sockets. The kqueue functionality can generally be replaced 1384 with routing sockets. 1385 138620090628: 1387 The documentation from the FreeBSD Documentation Project (Handbook, 1388 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1389 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1390 139120090624: 1392 The ABI of various structures related to the SYSV IPC API have been 1393 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1394 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1395 800100. 1396 139720090622: 1398 Layout of struct vnet has changed as routing related variables were 1399 moved to their own Vimage module. Modules need to be recompiled. Bump 1400 __FreeBSD_version to 800099. 1401 140220090619: 1403 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1404 respectively. As long as no more than 16 groups per process are used, 1405 no changes should be visible. When more than 16 groups are used, old 1406 binaries may fail if they call getgroups() or getgrouplist() with 1407 statically sized storage. Recompiling will work around this, but 1408 applications should be modified to use dynamically allocated storage 1409 for group arrays as POSIX.1-2008 does not cap an implementation's 1410 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1411 1412 NFS and portalfs mounts may also be affected as the list of groups is 1413 truncated to 16. Users of NFS who use more than 16 groups, should 1414 take care that negative group permissions are not used on the exported 1415 file systems as they will not be reliable unless a GSSAPI based 1416 authentication method is used. 1417 141820090616: 1419 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1420 option compiles in the support for adaptive spinning for lockmgrs 1421 which want to enable it. The lockinit() function now accepts the flag 1422 LK_ADAPTIVE in order to make the lock object subject to adaptive 1423 spinning when both held in write and read mode. 1424 142520090613: 1426 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1427 changed. User applications that use this ioctl need to be rebuilt. 1428 142920090611: 1430 The layout of struct thread has changed. Kernel and modules need to 1431 be rebuilt. 1432 143320090608: 1434 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1435 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1436 143720090602: 1438 window(1) has been removed from the base system. It can now be 1439 installed from ports. The port is called misc/window. 1440 144120090601: 1442 The way we are storing and accessing `routing table' entries has 1443 changed. Programs reading the FIB, like netstat, need to be 1444 re-compiled. 1445 144620090601: 1447 A new netisr implementation has been added for FreeBSD 8. Network 1448 file system modules, such as igmp, ipdivert, and others, should be 1449 rebuilt. 1450 Bump __FreeBSD_version to 800096. 1451 145220090530: 1453 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1454 more valid. 1455 145620090530: 1457 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1458 Bump __FreeBSD_version to 800094. 1459 146020090529: 1461 Add mnt_xflag field to 'struct mount'. File system modules need to be 1462 rebuilt. 1463 Bump __FreeBSD_version to 800093. 1464 146520090528: 1466 The compiling option ADAPTIVE_SX has been retired while it has been 1467 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1468 The KPI for sx_init_flags() changes as accepting flags: 1469 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1470 been introduced in order to handle the reversed logic. 1471 Bump __FreeBSD_version to 800092. 1472 147320090527: 1474 Add support for hierarchical jails. Remove global securelevel. 1475 Bump __FreeBSD_version to 800091. 1476 147720090523: 1478 The layout of struct vnet_net has changed, therefore modules 1479 need to be rebuilt. 1480 Bump __FreeBSD_version to 800090. 1481 148220090523: 1483 The newly imported zic(8) produces a new format in the output. Please 1484 run tzsetup(8) to install the newly created data to /etc/localtime. 1485 148620090520: 1487 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1488 hw.usb.* and is now consistent again with previous releases. 1489 149020090520: 1491 802.11 monitor mode support was revised and driver api's were changed. 1492 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1493 of DLT_IEEE802_11. No user-visible data structures were changed but 1494 applications that use DLT_IEEE802_11 may require changes. 1495 Bump __FreeBSD_version to 800088. 1496 149720090430: 1498 The layout of the following structs has changed: sysctl_oid, 1499 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1500 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1501 panics may be experienced. World rebuild is required for 1502 correctly checking networking state from userland. 1503 Bump __FreeBSD_version to 800085. 1504 150520090429: 1506 MLDv2 and Source-Specific Multicast (SSM) have been merged 1507 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1508 The implementation of SSM within FreeBSD's IPv6 stack closely 1509 follows the IPv4 implementation. 1510 1511 For kernel developers: 1512 1513 * The most important changes are that the ip6_output() and 1514 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1515 and this lock has been downgraded to a non-recursive mutex. 1516 1517 * As with the changes to the IPv4 stack to support SSM, filtering 1518 of inbound multicast traffic must now be performed by transport 1519 protocols within the IPv6 stack. This does not apply to TCP and 1520 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1521 1522 * The KPIs used by IPv6 multicast are similar to those used by 1523 the IPv4 stack, with the following differences: 1524 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1525 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1526 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1527 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1528 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1529 for MLDv1 have an additional 'timer' argument which is used to 1530 jitter the initial membership report for the solicited-node 1531 multicast membership on-link. 1532 * This is not strictly needed for MLDv2, which already jitters 1533 its report transmissions. However, the 'timer' argument is 1534 preserved in case MLDv1 is active on the interface. 1535 1536 * The KAME linked-list based IPv6 membership implementation has 1537 been refactored to use a vector similar to that used by the IPv4 1538 stack. 1539 Code which maintains a list of its own multicast memberships 1540 internally, e.g. carp, has been updated to reflect the new 1541 semantics. 1542 1543 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1544 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1545 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1546 implementation constraint which needs to be addressed in HEAD. 1547 1548 For application developers: 1549 1550 * The changes are broadly similar to those made for the IPv4 1551 stack. 1552 1553 * The use of IPv4 and IPv6 multicast socket options on the same 1554 socket, using mapped addresses, HAS NOT been tested or supported. 1555 1556 * There are a number of issues with the implementation of various 1557 IPv6 multicast APIs which need to be resolved in the API surface 1558 before the implementation is fully compatible with KAME userland 1559 use, and these are mostly to do with interface index treatment. 1560 1561 * The literature available discusses the use of either the delta / ASM 1562 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1563 using setsourcefilter(3)/getsourcefilter(3). For more information 1564 please refer to RFC 3768, 'Socket Interface Extensions for 1565 Multicast Source Filters'. 1566 1567 * Applications which use the published RFC 3678 APIs should be fine. 1568 1569 For systems administrators: 1570 1571 * The mtest(8) utility has been refactored to support IPv6, in 1572 addition to IPv4. Interface addresses are no longer accepted 1573 as arguments, their names must be used instead. The utility 1574 will map the interface name to its first IPv4 address as 1575 returned by getifaddrs(3). 1576 1577 * The ifmcstat(8) utility has also been updated to print the MLDv2 1578 endpoint state and source filter lists via sysctl(3). 1579 1580 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1581 loopback of IPv6 multicast datagrams by default; it defaults to 1 1582 to preserve the existing behaviour. Disabling multicast loopback is 1583 recommended for optimal system performance. 1584 1585 * The IPv6 MROUTING code has been changed to examine this sysctl 1586 instead of attempting to perform a group lookup before looping 1587 back forwarded datagrams. 1588 1589 Bump __FreeBSD_version to 800084. 1590 159120090422: 1592 Implement low-level Bluetooth HCI API. 1593 Bump __FreeBSD_version to 800083. 1594 159520090419: 1596 The layout of struct malloc_type, used by modules to register new 1597 memory allocation types, has changed. Most modules will need to 1598 be rebuilt or panics may be experienced. 1599 Bump __FreeBSD_version to 800081. 1600 160120090415: 1602 Anticipate overflowing inp_flags - add inp_flags2. 1603 This changes most offsets in inpcb, so checking v4 connection 1604 state will require a world rebuild. 1605 Bump __FreeBSD_version to 800080. 1606 160720090415: 1608 Add an llentry to struct route and struct route_in6. Modules 1609 embedding a struct route will need to be recompiled. 1610 Bump __FreeBSD_version to 800079. 1611 161220090414: 1613 The size of rt_metrics_lite and by extension rtentry has changed. 1614 Networking administration apps will need to be recompiled. 1615 The route command now supports show as an alias for get, weighting 1616 of routes, sticky and nostick flags to alter the behavior of stateful 1617 load balancing. 1618 Bump __FreeBSD_version to 800078. 1619 162020090408: 1621 Do not use Giant for kbdmux(4) locking. This is wrong and 1622 apparently causing more problems than it solves. This will 1623 re-open the issue where interrupt handlers may race with 1624 kbdmux(4) in polling mode. Typical symptoms include (but 1625 not limited to) duplicated and/or missing characters when 1626 low level console functions (such as gets) are used while 1627 interrupts are enabled (for example geli password prompt, 1628 mountroot prompt etc.). Disabling kbdmux(4) may help. 1629 163020090407: 1631 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1632 kernel modules referencing any of the above need to be recompiled. 1633 Bump __FreeBSD_version to 800075. 1634 163520090320: 1636 GEOM_PART has become the default partition slicer for storage devices, 1637 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1638 introduces some changes: 1639 1640 MSDOS/EBR: the devices created from MSDOS extended partition entries 1641 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1642 to devices with offset-based names. fstabs may need to be modified. 1643 1644 BSD: the "geometry does not match label" warning is harmless in most 1645 cases but it points to problems in file system misalignment with 1646 disk geometry. The "c" partition is now implicit, covers the whole 1647 top-level drive and cannot be (mis)used by users. 1648 1649 General: Kernel dumps are now not allowed to be written to devices 1650 whose partition types indicate they are meant to be used for file 1651 systems (or, in case of MSDOS partitions, as something else than 1652 the "386BSD" type). 1653 1654 Most of these changes date approximately from 200812. 1655 165620090319: 1657 The uscanner(4) driver has been removed from the kernel. This follows 1658 Linux removing theirs in 2.6 and making libusb the default interface 1659 (supported by sane). 1660 166120090319: 1662 The multicast forwarding code has been cleaned up. netstat(1) 1663 only relies on KVM now for printing bandwidth upcall meters. 1664 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1665 ip6_mroute_mod respectively. The config(5) options for statically 1666 compiling this code remain the same, i.e. 'options MROUTING'. 1667 166820090315: 1669 Support for the IFF_NEEDSGIANT network interface flag has been 1670 removed, which means that non-MPSAFE network device drivers are no 1671 longer supported. In particular, if_ar, if_sr, and network device 1672 drivers from the old (legacy) USB stack can no longer be built or 1673 used. 1674 167520090313: 1676 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1677 a bunch of new language catalog files have also been added. 1678 This means that some common libc messages are now localized and 1679 they depend on the LC_MESSAGES environmental variable. 1680 168120090313: 1682 The k8temp(4) driver has been renamed to amdtemp(4) since 1683 support for Family 10 and Family 11 CPU families was added. 1684 168520090309: 1686 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1687 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1688 1689 For kernel developers, the most important changes are that the 1690 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1691 and this lock has been downgraded to a non-recursive mutex. 1692 1693 Transport protocols (UDP, Raw IP) are now responsible for filtering 1694 inbound multicast traffic according to group membership and source 1695 filters. The imo_multicast_filter() KPI exists for this purpose. 1696 Transports which do not use multicast (SCTP, TCP) already reject 1697 multicast by default. Forwarding and receive performance may improve 1698 as a mutex acquisition is no longer needed in the ip_input() 1699 low-level input path. in_addmulti() and in_delmulti() are shimmed 1700 to new KPIs which exist to support SSM in-kernel. 1701 1702 For application developers, it is recommended that loopback of 1703 multicast datagrams be disabled for best performance, as this 1704 will still cause the lock to be taken for each looped-back 1705 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1706 be tuned to 0 to disable loopback by default; it defaults to 1 1707 to preserve the existing behaviour. 1708 1709 For systems administrators, to obtain best performance with 1710 multicast reception and multiple groups, it is always recommended 1711 that a card with a suitably precise hash filter is used. Hash 1712 collisions will still result in the lock being taken within the 1713 transport protocol input path to check group membership. 1714 1715 If deploying FreeBSD in an environment with IGMP snooping switches, 1716 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1717 enabled; this forces 224.0.0.0/24 group membership to be announced 1718 via IGMP. 1719 1720 The size of 'struct igmpstat' has changed; netstat needs to be 1721 recompiled to reflect this. 1722 Bump __FreeBSD_version to 800070. 1723 172420090309: 1725 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1726 updated to use it. This requires a buildworld/installworld in order to 1727 update the library and dependencies (usbconfig, etc). Its advisable to 1728 rebuild all ports which uses libusb. More specific directions are given 1729 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1730 libusb are no longer required and can be removed. 1731 173220090302: 1733 A workaround is committed to allow the creation of System V shared 1734 memory segment of size > 2 GB on the 64-bit architectures. 1735 Due to a limitation of the existing ABI, the shm_segsz member 1736 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1737 wrong for large segments. Note that limits must be explicitly 1738 raised to allow such segments to be created. 1739 174020090301: 1741 The layout of struct ifnet has changed, requiring a rebuild of all 1742 network device driver modules. 1743 174420090227: 1745 The /dev handling for the new USB stack has changed, a 1746 buildworld/installworld is required for libusb20. 1747 174820090223: 1749 The new USB2 stack has now been permanently moved in and all kernel and 1750 module names reverted to their previous values (eg, usb, ehci, ohci, 1751 ums, ...). The old usb stack can be compiled in by prefixing the name 1752 with the letter 'o', the old usb modules have been removed. 1753 Updating entry 20090216 for xorg and 20090215 for libmap may still 1754 apply. 1755 175620090217: 1757 The rc.conf(5) option if_up_delay has been renamed to 1758 defaultroute_delay to better reflect its purpose. If you have 1759 customized this setting in /etc/rc.conf you need to update it to 1760 use the new name. 1761 176220090216: 1763 xorg 7.4 wants to configure its input devices via hald which does not 1764 yet work with USB2. If the keyboard/mouse does not work in xorg then 1765 add 1766 Option "AllowEmptyInput" "off" 1767 to your ServerLayout section. This will cause X to use the configured 1768 kbd and mouse sections from your xorg.conf. 1769 177020090215: 1771 The GENERIC kernels for all architectures now default to the new USB2 1772 stack. No kernel config options or code have been removed so if a 1773 problem arises please report it and optionally revert to the old USB 1774 stack. If you are loading USB kernel modules or have a custom kernel 1775 that includes GENERIC then ensure that usb names are also changed over, 1776 eg uftdi -> usb2_serial_ftdi. 1777 1778 Older programs linked against the ports libusb 0.1 need to be 1779 redirected to the new stack's libusb20. /etc/libmap.conf can 1780 be used for this: 1781 # Map old usb library to new one for usb2 stack 1782 libusb-0.1.so.8 libusb20.so.1 1783 178420090209: 1785 All USB ethernet devices now attach as interfaces under the name ueN 1786 (eg. ue0). This is to provide a predictable name as vendors often 1787 change usb chipsets in a product without notice. 1788 178920090203: 1790 The ichsmb(4) driver has been changed to require SMBus slave 1791 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1792 All of the other SMBus controller drivers require left-justified 1793 slave addresses, so this change makes all the drivers provide the 1794 same interface. 1795 179620090201: 1797 INET6 statistics (struct ip6stat) was updated. 1798 netstat(1) needs to be recompiled. 1799 180020090119: 1801 NTFS has been removed from GENERIC kernel on amd64 to match 1802 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1803 will load ntfs.ko module automatically when NTFS support is 1804 actually needed, unless ntfs.ko is not installed or security 1805 level prohibits loading kernel modules. If either is the case, 1806 "options NTFS" has to be added into kernel config. 1807 180820090115: 1809 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1810 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1811 800061. User space tools that rely on the size of struct tcpcb in 1812 tcp_var.h (e.g. sockstat) need to be recompiled. 1813 181420081225: 1815 ng_tty(4) module updated to match the new TTY subsystem. 1816 Due to API change, user-level applications must be updated. 1817 New API support added to mpd5 CVS and expected to be present 1818 in next mpd5.3 release. 1819 182020081219: 1821 With __FreeBSD_version 800060 the makefs tool is part of 1822 the base system (it was a port). 1823 182420081216: 1825 The afdata and ifnet locks have been changed from mutexes to 1826 rwlocks, network modules will need to be re-compiled. 1827 182820081214: 1829 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1830 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1831 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1832 architecture and 40 bytes on 64-bit architecture. The userland 1833 applications "arp" and "ndp" have been updated accordingly. 1834 The output from "netstat -r" shows only routing entries and 1835 none of the L2 information. 1836 183720081130: 1838 __FreeBSD_version 800057 marks the switchover from the 1839 binary ath hal to source code. Users must add the line: 1840 1841 options AH_SUPPORT_AR5416 1842 1843 to their kernel config files when specifying: 1844 1845 device ath_hal 1846 1847 The ath_hal module no longer exists; the code is now compiled 1848 together with the driver in the ath module. It is now 1849 possible to tailor chip support (i.e. reduce the set of chips 1850 and thereby the code size); consult ath_hal(4) for details. 1851 185220081121: 1853 __FreeBSD_version 800054 adds memory barriers to 1854 <machine/atomic.h>, new interfaces to ifnet to facilitate 1855 multiple hardware transmit queues for cards that support 1856 them, and a lock-less ring-buffer implementation to 1857 enable drivers to more efficiently manage queueing of 1858 packets. 1859 186020081117: 1861 A new version of ZFS (version 13) has been merged to -HEAD. 1862 This version has zpool attribute "listsnapshots" off by 1863 default, which means "zfs list" does not show snapshots, 1864 and is the same as Solaris behavior. 1865 186620081028: 1867 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1868 186920081009: 1870 The uhci, ohci, ehci and slhci USB Host controller drivers have 1871 been put into separate modules. If you load the usb module 1872 separately through loader.conf you will need to load the 1873 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1874 controller add the following to loader.conf: 1875 1876 uhci_load="YES" 1877 ehci_load="YES" 1878 187920081009: 1880 The ABI used by the PMC toolset has changed. Please keep 1881 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1882 sync. 1883 188420081009: 1885 atapci kernel module now includes only generic PCI ATA 1886 driver. AHCI driver moved to ataahci kernel module. 1887 All vendor-specific code moved into separate kernel modules: 1888 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1889 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1890 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1891 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1892 189320080820: 1894 The TTY subsystem of the kernel has been replaced by a new 1895 implementation, which provides better scalability and an 1896 improved driver model. Most common drivers have been migrated to 1897 the new TTY subsystem, while others have not. The following 1898 drivers have not yet been ported to the new TTY layer: 1899 1900 PCI/ISA: 1901 cy, digi, rc, rp, sio 1902 1903 USB: 1904 ubser, ucycom 1905 1906 Line disciplines: 1907 ng_h4, ng_tty, ppp, sl, snp 1908 1909 Adding these drivers to your kernel configuration file shall 1910 cause compilation to fail. 1911 191220080818: 1913 ntpd has been upgraded to 4.2.4p5. 1914 191520080801: 1916 OpenSSH has been upgraded to 5.1p1. 1917 1918 For many years, FreeBSD's version of OpenSSH preferred DSA 1919 over RSA for host and user authentication keys. With this 1920 upgrade, we've switched to the vendor's default of RSA over 1921 DSA. This may cause upgraded clients to warn about unknown 1922 host keys even for previously known hosts. Users should 1923 follow the usual procedure for verifying host keys before 1924 accepting the RSA key. 1925 1926 This can be circumvented by setting the "HostKeyAlgorithms" 1927 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1928 command line. 1929 1930 Please note that the sequence of keys offered for 1931 authentication has been changed as well. You may want to 1932 specify IdentityFile in a different order to revert this 1933 behavior. 1934 193520080713: 1936 The sio(4) driver has been removed from the i386 and amd64 1937 kernel configuration files. This means uart(4) is now the 1938 default serial port driver on those platforms as well. 1939 1940 To prevent collisions with the sio(4) driver, the uart(4) driver 1941 uses different names for its device nodes. This means the 1942 onboard serial port will now most likely be called "ttyu0" 1943 instead of "ttyd0". You may need to reconfigure applications to 1944 use the new device names. 1945 1946 When using the serial port as a boot console, be sure to update 1947 /boot/device.hints and /etc/ttys before booting the new kernel. 1948 If you forget to do so, you can still manually specify the hints 1949 at the loader prompt: 1950 1951 set hint.uart.0.at="isa" 1952 set hint.uart.0.port="0x3F8" 1953 set hint.uart.0.flags="0x10" 1954 set hint.uart.0.irq="4" 1955 boot -s 1956 195720080609: 1958 The gpt(8) utility has been removed. Use gpart(8) to partition 1959 disks instead. 1960 196120080603: 1962 The version that Linuxulator emulates was changed from 2.4.2 1963 to 2.6.16. If you experience any problems with Linux binaries 1964 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1965 if it fixes the problem contact emulation mailing list. 1966 196720080525: 1968 ISDN4BSD (I4B) was removed from the src tree. You may need to 1969 update a your kernel configuration and remove relevant entries. 1970 197120080509: 1972 I have checked in code to support multiple routing tables. 1973 See the man pages setfib(1) and setfib(2). 1974 This is a hopefully backwards compatible version, 1975 but to make use of it you need to compile your kernel 1976 with options ROUTETABLES=2 (or more up to 16). 1977 197820080420: 1979 The 802.11 wireless support was redone to enable multi-bss 1980 operation on devices that are capable. The underlying device 1981 is no longer used directly but instead wlanX devices are 1982 cloned with ifconfig. This requires changes to rc.conf files. 1983 For example, change: 1984 ifconfig_ath0="WPA DHCP" 1985 to 1986 wlans_ath0=wlan0 1987 ifconfig_wlan0="WPA DHCP" 1988 see rc.conf(5) for more details. In addition, mergemaster of 1989 /etc/rc.d is highly recommended. Simultaneous update of userland 1990 and kernel wouldn't hurt either. 1991 1992 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1993 modules were merged into the base wlan module. All references 1994 to these modules (e.g. in kernel config files) must be removed. 1995 199620080408: 1997 psm(4) has gained write(2) support in native operation level. 1998 Arbitrary commands can be written to /dev/psm%d and status can 1999 be read back from it. Therefore, an application is responsible 2000 for status validation and error recovery. It is a no-op in 2001 other operation levels. 2002 200320080312: 2004 Support for KSE threading has been removed from the kernel. To 2005 run legacy applications linked against KSE libmap.conf may 2006 be used. The following libmap.conf may be used to ensure 2007 compatibility with any prior release: 2008 2009 libpthread.so.1 libthr.so.1 2010 libpthread.so.2 libthr.so.2 2011 libkse.so.3 libthr.so.3 2012 201320080301: 2014 The layout of struct vmspace has changed. This affects libkvm 2015 and any executables that link against libkvm and use the 2016 kvm_getprocs() function. In particular, but not exclusively, 2017 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2018 The effects are minimal, but it's advisable to upgrade world 2019 nonetheless. 2020 202120080229: 2022 The latest em driver no longer has support in it for the 2023 82575 adapter, this is now moved to the igb driver. The 2024 split was done to make new features that are incompatible 2025 with older hardware easier to do. 2026 202720080220: 2028 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2029 likewise the kernel option is now GEOM_LINUX_LVM. 2030 203120080211: 2032 The default NFS mount mode has changed from UDP to TCP for 2033 increased reliability. If you rely on (insecurely) NFS 2034 mounting across a firewall you may need to update your 2035 firewall rules. 2036 203720080208: 2038 Belatedly note the addition of m_collapse for compacting 2039 mbuf chains. 2040 204120080126: 2042 The fts(3) structures have been changed to use adequate 2043 integer types for their members and so to be able to cope 2044 with huge file trees. The old fts(3) ABI is preserved 2045 through symbol versioning in libc, so third-party binaries 2046 using fts(3) should still work, although they will not take 2047 advantage of the extended types. At the same time, some 2048 third-party software might fail to build after this change 2049 due to unportable assumptions made in its source code about 2050 fts(3) structure members. Such software should be fixed 2051 by its vendor or, in the worst case, in the ports tree. 2052 FreeBSD_version 800015 marks this change for the unlikely 2053 case that a portable fix is impossible. 2054 205520080123: 2056 To upgrade to -current after this date, you must be running 2057 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2058 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2059 206020071128: 2061 The ADAPTIVE_GIANT kernel option has been retired because its 2062 functionality is the default now. 2063 206420071118: 2065 The AT keyboard emulation of sunkbd(4) has been turned on 2066 by default. In order to make the special symbols of the Sun 2067 keyboards driven by sunkbd(4) work under X these now have 2068 to be configured the same way as Sun USB keyboards driven 2069 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2070 2071 Option "XkbLayout" "us" 2072 Option "XkbRules" "xorg" 2073 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2074 207520071024: 2076 It has been decided that it is desirable to provide ABI 2077 backwards compatibility to the FreeBSD 4/5/6 versions of the 2078 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2079 broken with the introduction of PCI domain support (see the 2080 20070930 entry). Unfortunately, this required the ABI of 2081 PCIOCGETCONF to be broken again in order to be able to 2082 provide backwards compatibility to the old version of that 2083 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2084 again. As for prominent ports this affects neither pciutils 2085 nor xorg-server this time, the hal port needs to be rebuilt 2086 however. 2087 208820071020: 2089 The misnamed kthread_create() and friends have been renamed 2090 to kproc_create() etc. Many of the callers already 2091 used kproc_start().. 2092 I will return kthread_create() and friends in a while 2093 with implementations that actually create threads, not procs. 2094 Renaming corresponds with version 800002. 2095 209620071010: 2097 RELENG_7 branched. 2098 2099COMMON ITEMS: 2100 2101 General Notes 2102 ------------- 2103 Avoid using make -j when upgrading. While generally safe, there are 2104 sometimes problems using -j to upgrade. If your upgrade fails with 2105 -j, please try again without -j. From time to time in the past there 2106 have been problems using -j with buildworld and/or installworld. This 2107 is especially true when upgrading between "distant" versions (eg one 2108 that cross a major release boundary or several minor releases, or when 2109 several months have passed on the -current branch). 2110 2111 Sometimes, obscure build problems are the result of environment 2112 poisoning. This can happen because the make utility reads its 2113 environment when searching for values for global variables. To run 2114 your build attempts in an "environmental clean room", prefix all make 2115 commands with 'env -i '. See the env(1) manual page for more details. 2116 2117 When upgrading from one major version to another it is generally best 2118 to upgrade to the latest code in the currently installed branch first, 2119 then do an upgrade to the new branch. This is the best-tested upgrade 2120 path, and has the highest probability of being successful. Please try 2121 this approach before reporting problems with a major version upgrade. 2122 2123 When upgrading a live system, having a root shell around before 2124 installing anything can help undo problems. Not having a root shell 2125 around can lead to problems if pam has changed too much from your 2126 starting point to allow continued authentication after the upgrade. 2127 2128 ZFS notes 2129 --------- 2130 When upgrading the boot ZFS pool to a new version, always follow 2131 these two steps: 2132 2133 1.) recompile and reinstall the ZFS boot loader and boot block 2134 (this is part of "make buildworld" and "make installworld") 2135 2136 2.) update the ZFS boot block on your boot drive 2137 2138 The following example updates the ZFS boot block on the first 2139 partition (freebsd-boot) of a GPT partitioned drive ad0: 2140 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2141 2142 Non-boot pools do not need these updates. 2143 2144 To build a kernel 2145 ----------------- 2146 If you are updating from a prior version of FreeBSD (even one just 2147 a few days old), you should follow this procedure. It is the most 2148 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2149 2150 make kernel-toolchain 2151 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2152 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2153 2154 To test a kernel once 2155 --------------------- 2156 If you just want to boot a kernel once (because you are not sure 2157 if it works, or if you want to boot a known bad kernel to provide 2158 debugging information) run 2159 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2160 nextboot -k testkernel 2161 2162 To just build a kernel when you know that it won't mess you up 2163 -------------------------------------------------------------- 2164 This assumes you are already running a CURRENT system. Replace 2165 ${arch} with the architecture of your machine (e.g. "i386", 2166 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2167 2168 cd src/sys/${arch}/conf 2169 config KERNEL_NAME_HERE 2170 cd ../compile/KERNEL_NAME_HERE 2171 make depend 2172 make 2173 make install 2174 2175 If this fails, go to the "To build a kernel" section. 2176 2177 To rebuild everything and install it on the current system. 2178 ----------------------------------------------------------- 2179 # Note: sometimes if you are running current you gotta do more than 2180 # is listed here if you are upgrading from a really old current. 2181 2182 <make sure you have good level 0 dumps> 2183 make buildworld 2184 make kernel KERNCONF=YOUR_KERNEL_HERE 2185 [1] 2186 <reboot in single user> [3] 2187 mergemaster -p [5] 2188 make installworld 2189 mergemaster -i [4] 2190 make delete-old [6] 2191 <reboot> 2192 2193 To cross-install current onto a separate partition 2194 -------------------------------------------------- 2195 # In this approach we use a separate partition to hold 2196 # current's root, 'usr', and 'var' directories. A partition 2197 # holding "/", "/usr" and "/var" should be about 2GB in 2198 # size. 2199 2200 <make sure you have good level 0 dumps> 2201 <boot into -stable> 2202 make buildworld 2203 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2204 <maybe newfs current's root partition> 2205 <mount current's root partition on directory ${CURRENT_ROOT}> 2206 make installworld DESTDIR=${CURRENT_ROOT} 2207 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2208 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2209 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2210 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2211 <reboot into current> 2212 <do a "native" rebuild/install as described in the previous section> 2213 <maybe install compatibility libraries from ports/misc/compat*> 2214 <reboot> 2215 2216 2217 To upgrade in-place from stable to current 2218 ---------------------------------------------- 2219 <make sure you have good level 0 dumps> 2220 make buildworld [9] 2221 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2222 [1] 2223 <reboot in single user> [3] 2224 mergemaster -p [5] 2225 make installworld 2226 mergemaster -i [4] 2227 make delete-old [6] 2228 <reboot> 2229 2230 Make sure that you've read the UPDATING file to understand the 2231 tweaks to various things you need. At this point in the life 2232 cycle of current, things change often and you are on your own 2233 to cope. The defaults can also change, so please read ALL of 2234 the UPDATING entries. 2235 2236 Also, if you are tracking -current, you must be subscribed to 2237 freebsd-current@freebsd.org. Make sure that before you update 2238 your sources that you have read and understood all the recent 2239 messages there. If in doubt, please track -stable which has 2240 much fewer pitfalls. 2241 2242 [1] If you have third party modules, such as vmware, you 2243 should disable them at this point so they don't crash your 2244 system on reboot. 2245 2246 [3] From the bootblocks, boot -s, and then do 2247 fsck -p 2248 mount -u / 2249 mount -a 2250 cd src 2251 adjkerntz -i # if CMOS is wall time 2252 Also, when doing a major release upgrade, it is required that 2253 you boot into single user mode to do the installworld. 2254 2255 [4] Note: This step is non-optional. Failure to do this step 2256 can result in a significant reduction in the functionality of the 2257 system. Attempting to do it by hand is not recommended and those 2258 that pursue this avenue should read this file carefully, as well 2259 as the archives of freebsd-current and freebsd-hackers mailing lists 2260 for potential gotchas. The -U option is also useful to consider. 2261 See mergemaster(8) for more information. 2262 2263 [5] Usually this step is a noop. However, from time to time 2264 you may need to do this if you get unknown user in the following 2265 step. It never hurts to do it all the time. You may need to 2266 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2267 install) after the buildworld before this step if you last updated 2268 from current before 20130425 or from -stable before 20130430. 2269 2270 [6] This only deletes old files and directories. Old libraries 2271 can be deleted by "make delete-old-libs", but you have to make 2272 sure that no program is using those libraries anymore. 2273 2274 [8] In order to have a kernel that can run the 4.x binaries needed to 2275 do an installworld, you must include the COMPAT_FREEBSD4 option in 2276 your kernel. Failure to do so may leave you with a system that is 2277 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2278 required to run the 5.x binaries on more recent kernels. And so on 2279 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2280 2281 Make sure that you merge any new devices from GENERIC since the 2282 last time you updated your kernel config file. 2283 2284 [9] When checking out sources, you must include the -P flag to have 2285 cvs prune empty directories. 2286 2287 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2288 "?=" instead of the "=" assignment operator, so that buildworld can 2289 override the CPUTYPE if it needs to. 2290 2291 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2292 not on the command line, or in /etc/make.conf. buildworld will 2293 warn if it is improperly defined. 2294FORMAT: 2295 2296This file contains a list, in reverse chronological order, of major 2297breakages in tracking -current. It is not guaranteed to be a complete 2298list of such breakages, and only contains entries since October 10, 2007. 2299If you need to see UPDATING entries from before that date, you will need 2300to fetch an UPDATING file from an older FreeBSD release. 2301 2302Copyright information: 2303 2304Copyright 1998-2009 M.
