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 1920151104 p24 FreeBSD-SA-15:25.ntp [revised] 20 FreeBSD-EN-15:19.kqueue 21 FreeBSD-EN-15:20.vm 22 23 Fix regression in ntpd(8) lacking support for RAWDCF reference 24 clock in 10.1-RELEASE-p23. [SA-15:25.ntp] 25 26 Fix kqueue write events never fired for files greater 2GB. [EN-15:19] 27 28 Fix applications exiting due to segmentation violation on a correct 29 memory address. [EN-15:20] 30 3120151026: p23 FreeBSD-SA-15:25.ntp 32 33 Fix multiple NTP vulnerabilities. New NTP version is 4.2.8p4. 34 35 The configuration file syntax has been changed, thus mergemaster 36 run is recommended. Now the "kod" parameter requires "limited" 37 parameter. If the ntp.conf is not updated, the ntpd will run 38 successfully, but with KoD disabled. 39 4020151002: p22 FreeBSD-SA-15:24.rpcbind [revised] 41 Revised patch to address a regression that prevents NIS from working. 42 4320150929: p21 FreeBSD-SA-15:24.rpcbind 44 45 Fix rpcbind(8) remote denial of service.

[EN-15:05] 126 12720150407: p9 FreeBSD-SA-15:04.igmp [revised] 128 FreeBSD-SA-15:07.ntp 129 FreeBSD-SA-15:08.bsdinstall 130 FreeBSD-SA-15:09.ipv6 131 132 Improved patch for SA-15:04.igmp. 133 134 Fix multiple vulnerabilities of ntp. [SA-15:07] 135 136 Fix bsdinstall(8) insecure default GELI keyfile permissions. [SA-15:08] 137 138 Fix Denial of Service with IPv6 Router Advertisements. [SA-15:09] 139 14020150320: p8 141 Fix patch for SA-15:06.openssl. 142 14320150319: p7 FreeBSD-SA-15:06.openssl 144 Fix multiple vulnerabilities in OpenSSL. [SA-15:06] 145 14620150225: p6 FreeBSD-SA-15:04.igmp 147 FreeBSD-EN-15:01.vt 148 FreeBSD-EN-15:02.openssl 149 FreeBSD-EN-15:03.freebsd-update 150 151 Fix integer overflow in IGMP protocol.

[SA-15:02] 164 165 Fix SCTP stream reset vulnerability. [SA-15:03] 166 16720150114: p4 FreeBSD-SA-15:01.openssl 168 Fix multiple vulnerabilities in OpenSSL. [SA-15:01] 169 17020141223: p3 FreeBSD-SA-14:31.ntp 171 FreeBSD-EN-14:13.freebsd-update 172 173 Fix multiple vulnerabilities in NTP suite. [SA-14:31] 174 Fix directory deletion issue in freebsd-update. [EN-14:13] 175 17620141217: p2 FreeBSD-SA-14:30.unbound 177 Fix unbound remote denial of service vulnerability. 178 17920141210: p1 FreeBSD-SA-14:27.stdio 180 FreeBSD-SA-14:28.file 181 182 Fix buffer overflow in stdio. [SA-14:27] 183 184 Fix multiple vulnerabilities in file(1) and libmagic(3). 185 [SA-14:28] 186 18720140904: 188 The ofwfb driver, used to provide a graphics console on PowerPC when 189 using vt(4), no longer allows mmap() of all of physical memory. This 190 will prevent Xorg on PowerPC with some ATI graphics cards from 191 initializing properly unless x11-servers/xorg-server is updated to 192 1.12.4_8 or newer. 193 19420140831: 195 The libatf-c and libatf-c++ major versions were downgraded to 0 and 196 1 respectively to match the upstream numbers. They were out of 197 sync because, when they were originally added to FreeBSD, the 198 upstream versions were not respected. These libraries are private 199 and not yet built by default, so renumbering them should be a 200 non-issue. However, unclean source trees will yield broken test 201 programs once the operator executes "make delete-old-libs" after a 202 "make installworld". 203 204 Additionally, the atf-sh binary was made private by moving it into 205 /usr/libexec/. Already-built shell test programs will keep the 206 path to the old binary so they will break after "make delete-old" 207 is run. 208 209 If you are using WITH_TESTS=yes (not the default), wipe the object 210 tree and rebuild from scratch to prevent spurious test failures. 211 This is only needed once: the misnumbered libraries and misplaced 212 binaries have been added to OptionalObsoleteFiles.inc so they will 213 be removed during a clean upgrade. 214 21520140814: 216 The ixgbe tunables now match their sysctl counterparts, for example: 217 hw.ixgbe.enable_aim => hw.ix.enable_aim 218 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 219 22020140801: 221 The NFSv4.1 server committed by r269398 changes the internal 222 function call interfaces used between the NFS and krpc modules. 223 As such, __FreeBSD_version was bumped. 224 22520140729: 226 The default unbound configuration has been modified to address 227 issues with reverse lookups on networks that use private 228 address ranges. If you use the local_unbound service, run 229 "service local_unbound setup" as root to regenerate your 230 configuration, then "service local_unbound reload" to load the 231 new configuration. 232 23320140717: 234 It is no longer necessary to include the dwarf version in your DEBUG 235 options in your kernel config file. The bug that required it to be 236 placed in the config file has bene fixed. DEBUG should now just 237 contain -g. The build system will automatically update things 238 to do the right thing. 239 24020140715: 241 Several ABI breaking changes were merged to CTL and new iSCSI code. 242 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 243 iscsictl need to be rebuilt to work with a new kernel. 244 24520140708: 246 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 247 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 248 which differs from the behaviour controlled by this knob.) 249 25020140608: 251 On i386 and amd64 systems, the onifconsole flag is now set by default 252 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 253 as a login TTY if it is set in the bootloader as an active kernel 254 console. No changes in behavior should result otherwise. To revert to 255 the previous behavior, set ttyu0 to "off" in /etc/ttys. 256 25720140512: 258 Clang and llvm have been upgraded to 3.4.1 release. 259 26020140321: 261 Clang and llvm have been upgraded to 3.4 release. 262 26320140306: 264 If a Makefile in a tests/ directory was auto-generating a Kyuafile 265 instead of providing an explicit one, this would prevent such 266 Makefile from providing its own Kyuafile in the future during 267 NO_CLEAN builds. This has been fixed in the Makefiles but manual 268 intervention is needed to clean an objdir if you use NO_CLEAN: 269 # find /usr/obj -name Kyuafile | xargs rm -f 270 27120140303: 272 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 273 capability mode support. Please note that enabling the feature in 274 kernel is still highly recommended. 275 27620140227: 277 OpenSSH is now built with sandbox support, and will use sandbox as 278 the default privilege separation method. This requires Capsicum 279 capability mode support in kernel. 280 28120140216: 282 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 283 been deprecated and will not be part of FreeBSD 11.0 and later 284 releases. If you use this driver, please consider switching to 285 the nfe(4) driver instead. 286 28720140120: 288 10.0-RELEASE. 289 29020131216: 291 The behavior of gss_pseudo_random() for the krb5 mechanism 292 has changed, for applications requesting a longer random string 293 than produced by the underlying enctype's pseudo-random() function. 294 In particular, the random string produced from a session key of 295 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 296 be different at the 17th octet and later, after this change. 297 The counter used in the PRF+ construction is now encoded as a 298 big-endian integer in accordance with RFC 4402. 299 __FreeBSD_version is bumped to 1000701. 300 30120131108: 302 The WITHOUT_ATF build knob has been removed and its functionality 303 has been subsumed into the more generic WITHOUT_TESTS. If you were 304 using the former to disable the build of the ATF libraries, you 305 should change your settings to use the latter. 306 30720131031: 308 The default version of mtree is nmtree which is obtained from 309 NetBSD. The output is generally the same, but may vary 310 slightly. If you found you need identical output adding 311 "-F freebsd9" to the command line should do the trick. For the 312 time being, the old mtree is available as fmtree. 313 31420131014: 315 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 316 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 317 1.1.4_8 and verify bsdyml not linked in, before running "make 318 delete-old-libs": 319 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 320 or 321 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 322 32320131010: 324 The rc.d/jail script has been updated to support jail(8) 325 configuration file. The "jail_<jname>_*" rc.conf(5) variables 326 for per-jail configuration are automatically converted to 327 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 328 This is transparently backward compatible. See below about some 329 incompatibilities and rc.conf(5) manual page for more details. 330 331 These variables are now deprecated in favor of jail(8) configuration 332 file. One can use "rc.d/jail config <jname>" command to generate 333 a jail(8) configuration file in /var/run/jail.<jname>.conf without 334 running the jail(8) utility. The default pathname of the 335 configuration file is /etc/jail.conf and can be specified by 336 using $jail_conf or $jail_<jname>_conf variables. 337 338 Please note that jail_devfs_ruleset accepts an integer at 339 this moment. Please consider to rewrite the ruleset name 340 with an integer. 341 34220130930: 343 BIND has been removed from the base system. If all you need 344 is a local resolver, simply enable and start the local_unbound 345 service instead. Otherwise, several versions of BIND are 346 available in the ports tree. The dns/bind99 port is one example. 347 348 With this change, nslookup(1) and dig(1) are no longer in the base 349 system. Users should instead use host(1) and drill(1) which are 350 in the base system. Alternatively, nslookup and dig can 351 be obtained by installing the dns/bind-tools port. 352 35320130916: 354 With the addition of unbound(8), a new unbound user is now 355 required during installworld. "mergemaster -p" can be used to 356 add the user prior to installworld, as documented in the handbook. 357 35820130911: 359 OpenSSH is now built with DNSSEC support, and will by default 360 silently trust signed SSHFP records. This can be controlled with 361 the VerifyHostKeyDNS client configuration setting. DNSSEC support 362 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 363 36420130906: 365 The GNU Compiler Collection and C++ standard library (libstdc++) 366 are no longer built by default on platforms where clang is the system 367 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 368 options in src.conf. 369 37020130905: 371 The PROCDESC kernel option is now part of the GENERIC kernel 372 configuration and is required for the rwhod(8) to work. 373 If you are using custom kernel configuration, you should include 374 'options PROCDESC'. 375 37620130905: 377 The API and ABI related to the Capsicum framework was modified 378 in backward incompatible way. The userland libraries and programs 379 have to be recompiled to work with the new kernel. This includes the 380 following libraries and programs, but the whole buildworld is 381 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 382 kdump, procstat, rwho, rwhod, uniq. 383 38420130903: 385 AES-NI intrinsic support has been added to gcc. The AES-NI module 386 has been updated to use this support. A new gcc is required to build 387 the aesni module on both i386 and amd64. 388 38920130821: 390 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 391 Thus "device padlock_rng" and "device rdrand_rng" should be 392 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 393 39420130813: 395 WITH_ICONV has been split into two feature sets. WITH_ICONV now 396 enables just the iconv* functionality and is now on by default. 397 WITH_LIBICONV_COMPAT enables the libiconv api and link time 398 compatability. Set WITHOUT_ICONV to build the old way. 399 If you have been using WITH_ICONV before, you will very likely 400 need to turn on WITH_LIBICONV_COMPAT. 401 40220130806: 403 INVARIANTS option now enables DEBUG for code with OpenSolaris and 404 Illumos origin, including ZFS. If you have INVARIANTS in your 405 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 406 explicitly. 407 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 408 locks if WITNESS option was set. Because that generated a lot of 409 witness(9) reports and all of them were believed to be false 410 positives, this is no longer done. New option OPENSOLARIS_WITNESS 411 can be used to achieve the previous behavior. 412 41320130806: 414 Timer values in IPv6 data structures now use time_uptime instead 415 of time_second. Although this is not a user-visible functional 416 change, userland utilities which directly use them---ndp(8), 417 rtadvd(8), and rtsold(8) in the base system---need to be updated 418 to r253970 or later. 419 42020130802: 421 find -delete can now delete the pathnames given as arguments, 422 instead of only files found below them or if the pathname did 423 not contain any slashes. Formerly, the following error message 424 would result: 425 426 find: -delete: <path>: relative path potentially not safe 427 428 Deleting the pathnames given as arguments can be prevented 429 without error messages using -mindepth 1 or by changing 430 directory and passing "." as argument to find. This works in the 431 old as well as the new version of find. 432 43320130726: 434 Behavior of devfs rules path matching has been changed. 435 Pattern is now always matched against fully qualified devfs 436 path and slash characters must be explicitly matched by 437 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 438 subdirectories must be reviewed. 439 44020130716: 441 The default ARM ABI has changed to the ARM EABI. The old ABI is 442 incompatible with the ARM EABI and all programs and modules will 443 need to be rebuilt to work with a new kernel. 444 445 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 446 447 NOTE: Support for the old ABI will be removed in the future and 448 users are advised to upgrade. 449 45020130709: 451 pkg_install has been disconnected from the build if you really need it 452 you should add WITH_PKGTOOLS in your src.conf(5). 453 45420130709: 455 Most of network statistics structures were changed to be able 456 keep 64-bits counters. Thus all tools, that work with networking 457 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 458 45920130629: 460 Fix targets that run multiple make's to use && rather than ; 461 so that subsequent steps depend on success of previous. 462 463 NOTE: if building 'universe' with -j* on stable/8 or stable/9 464 it would be better to start the build using bmake, to avoid 465 overloading the machine. 466 46720130618: 468 Fix a bug that allowed a tracing process (e.g. gdb) to write 469 to a memory-mapped file in the traced process's address space 470 even if neither the traced process nor the tracing process had 471 write access to that file. 472 47320130615: 474 CVS has been removed from the base system. An exact copy 475 of the code is available from the devel/cvs port. 476 47720130613: 478 Some people report the following error after the switch to bmake: 479 480 make: illegal option -- J 481 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 482 ... 483 *** [buildworld] Error code 2 484 485 this likely due to an old instance of make in 486 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 487 which src/Makefile will use that blindly, if it exists, so if 488 you see the above error: 489 490 rm -rf `make -V MAKEPATH` 491 492 should resolve it. 493 49420130516: 495 Use bmake by default. 496 Whereas before one could choose to build with bmake via 497 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 498 make. The goal is to remove these knobs for 10-RELEASE. 499 500 It is worth noting that bmake (like gmake) treats the command 501 line as the unit of failure, rather than statements within the 502 command line. Thus '(cd some/where && dosomething)' is safer 503 than 'cd some/where; dosomething'. The '()' allows consistent 504 behavior in parallel build. 505 50620130429: 507 Fix a bug that allows NFS clients to issue READDIR on files. 508 50920130426: 510 The WITHOUT_IDEA option has been removed because 511 the IDEA patent expired. 512 51320130426: 514 The sysctl which controls TRIM support under ZFS has been renamed 515 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 516 enabled by default. 517 51820130425: 519 The mergemaster command now uses the default MAKEOBJDIRPREFIX 520 rather than creating it's own in the temporary directory in 521 order allow access to bootstrapped versions of tools such as 522 install and mtree. When upgrading from version of FreeBSD where 523 the install command does not support -l, you will need to 524 install a new mergemaster command if mergemaster -p is required. 525 This can be accomplished with the command (cd src/usr.sbin/mergemaster 526 && make install). 527 52820130404: 529 Legacy ATA stack, disabled and replaced by new CAM-based one since 530 FreeBSD 9.0, completely removed from the sources. Kernel modules 531 atadisk and atapi*, user-level tools atacontrol and burncd are 532 removed. Kernel option `options ATA_CAM` is now permanently enabled 533 and removed. 534 53520130319: 536 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 537 and socketpair(2). Software, in particular Kerberos, may 538 automatically detect and use these during building. The resulting 539 binaries will not work on older kernels. 540 54120130308: 542 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 543 information, see the respective 20130304 entry). 544 54520130304: 546 Recent commits to callout(9) changed the size of struct callout, 547 so the KBI is probably heavily disturbed. Also, some functions 548 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 549 by macros. Every kernel module using it won't load, so rebuild 550 is requested. 551 552 The ctl device has been re-enabled in GENERIC for i386 and amd64, 553 but does not initialize by default (because of the new CTL_DISABLE 554 option) to save memory. To re-enable it, remove the CTL_DISABLE 555 option from the kernel config file or set kern.cam.ctl.disable=0 556 in /boot/loader.conf. 557 55820130301: 559 The ctl device has been disabled in GENERIC for i386 and amd64. 560 This was done due to the extra memory being allocated at system 561 initialisation time by the ctl driver which was only used if 562 a CAM target device was created. This makes a FreeBSD system 563 unusable on 128MB or less of RAM. 564 56520130208: 566 A new compression method (lz4) has been merged to -HEAD. Please 567 refer to zpool-features(7) for more information. 568 569 Please refer to the "ZFS notes" section of this file for information 570 on upgrading boot ZFS pools. 571 57220130129: 573 A BSD-licensed patch(1) variant has been added and is installed 574 as bsdpatch, being the GNU version the default patch. 575 To inverse the logic and use the BSD-licensed one as default, 576 while having the GNU version installed as gnupatch, rebuild 577 and install world with the WITH_BSD_PATCH knob set. 578 57920130121: 580 Due to the use of the new -l option to install(1) during build 581 and install, you must take care not to directly set the INSTALL 582 make variable in your /etc/make.conf, /etc/src.conf, or on the 583 command line. If you wish to use the -C flag for all installs 584 you may be able to add INSTALL+=-C to /etc/make.conf or 585 /etc/src.conf. 586 58720130118: 588 The install(1) option -M has changed meaning and now takes an 589 argument that is a file or path to append logs to. In the 590 unlikely event that -M was the last option on the command line 591 and the command line contained at least two files and a target 592 directory the first file will have logs appended to it. The -M 593 option served little practical purpose in the last decade so its 594 use is expected to be extremely rare. 595 59620121223: 597 After switching to Clang as the default compiler some users of ZFS 598 on i386 systems started to experience stack overflow kernel panics. 599 Please consider using 'options KSTACK_PAGES=4' in such configurations. 600 60120121222: 602 GEOM_LABEL now mangles label names read from file system metadata. 603 Mangling affect labels containing spaces, non-printable characters, 604 '%' or '"'. Device names in /etc/fstab and other places may need to 605 be updated. 606 60720121217: 608 By default, only the 10 most recent kernel dumps will be saved. To 609 restore the previous behaviour (no limit on the number of kernel dumps 610 stored in the dump directory) add the following line to /etc/rc.conf: 611 612 savecore_flags="" 613 61420121201: 615 With the addition of auditdistd(8), a new auditdistd user is now 616 required during installworld. "mergemaster -p" can be used to 617 add the user prior to installworld, as documented in the handbook. 618 61920121117: 620 The sin6_scope_id member variable in struct sockaddr_in6 is now 621 filled by the kernel before passing the structure to the userland via 622 sysctl or routing socket. This means the KAME-specific embedded scope 623 id in sin6_addr.s6_addr[2] is always cleared in userland application. 624 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 625 __FreeBSD_version is bumped to 1000025. 626 62720121105: 628 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 629 This means that the world and kernel will be compiled with clang 630 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 631 and /usr/bin/cpp. To disable this behavior and revert to building 632 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 633 of current may need to bootstrap WITHOUT_CLANG first if the clang 634 build fails (its compatibility window doesn't extend to the 9 stable 635 branch point). 636 63720121102: 638 The IPFIREWALL_FORWARD kernel option has been removed. Its 639 functionality now turned on by default. 640 64120121023: 642 The ZERO_COPY_SOCKET kernel option has been removed and 643 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 644 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 645 mechanism which is not safe and may result in kernel crashes. 646 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 647 driver supports disposeable external page sized mbuf storage. 648 Proper replacements for both zero-copy mechanisms are under 649 consideration and will eventually lead to complete removal 650 of the two kernel options. 651 65220121023: 653 The IPv4 network stack has been converted to network byte 654 order. The following modules need to be recompiled together 655 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 656 pf(4), ipfw(4), ng_ipfw(4), stf(4). 657 65820121022: 659 Support for non-MPSAFE filesystems was removed from VFS. The 660 VFS_VERSION was bumped, all filesystem modules shall be 661 recompiled. 662 66320121018: 664 All the non-MPSAFE filesystems have been disconnected from 665 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 666 portalfs, smbfs, xfs. 667 66820121016: 669 The interface cloning API and ABI has changed. The following 670 modules need to be recompiled together with kernel: 671 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 672 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 673 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 674 67520121015: 676 The sdhci driver was split in two parts: sdhci (generic SD Host 677 Controller logic) and sdhci_pci (actual hardware driver). 678 No kernel config modifications are required, but if you 679 load sdhc as a module you must switch to sdhci_pci instead. 680 68120121014: 682 Import the FUSE kernel and userland support into base system. 683 68420121013: 685 The GNU sort(1) program has been removed since the BSD-licensed 686 sort(1) has been the default for quite some time and no serious 687 problems have been reported. The corresponding WITH_GNU_SORT 688 knob has also gone. 689 69020121006: 691 The pfil(9) API/ABI for AF_INET family has been changed. Packet 692 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 693 with new kernel. 694 69520121001: 696 The net80211(4) ABI has been changed to allow for improved driver 697 PS-POLL and power-save support. All wireless drivers need to be 698 recompiled to work with the new kernel. 699 70020120913: 701 The random(4) support for the VIA hardware random number 702 generator (`PADLOCK') is no longer enabled unconditionally. 703 Add the padlock_rng device in the custom kernel config if 704 needed. The GENERIC kernels on i386 and amd64 do include the 705 device, so the change only affects the custom kernel 706 configurations. 707 70820120908: 709 The pf(4) packet filter ABI has been changed. pfctl(8) and 710 snmp_pf module need to be recompiled to work with new kernel. 711 71220120828: 713 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 714 to -HEAD. Pools that have empty_bpobj in active state can not be 715 imported read-write with ZFS implementations that do not support 716 this feature. For more information read the zpool-features(5) 717 manual page. 718 71920120727: 720 The sparc64 ZFS loader has been changed to no longer try to auto- 721 detect ZFS providers based on diskN aliases but now requires these 722 to be explicitly listed in the OFW boot-device environment variable. 723 72420120712: 725 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 726 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 727 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 728 72920120712: 730 The following sysctls and tunables have been renamed for consistency 731 with other variables: 732 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 733 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 734 73520120628: 736 The sort utility has been replaced with BSD sort. For now, GNU sort 737 is also available as "gnusort" or the default can be set back to 738 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 739 installed as "bsdsort". 740 74120120611: 742 A new version of ZFS (pool version 5000) has been merged to -HEAD. 743 Starting with this version the old system of ZFS pool versioning 744 is superseded by "feature flags". This concept enables forward 745 compatibility against certain future changes in functionality of ZFS 746 pools. The first read-only compatible "feature flag" for ZFS pools 747 is named "com.delphix:async_destroy". For more information 748 read the new zpool-features(5) manual page. 749 Please refer to the "ZFS notes" section of this file for information 750 on upgrading boot ZFS pools. 751 75220120417: 753 The malloc(3) implementation embedded in libc now uses sources imported 754 as contrib/jemalloc. The most disruptive API change is to 755 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 756 delete it prior to installworld, and optionally re-create it using the 757 new format after rebooting. See malloc.conf(5) for details 758 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 759 NAMESPACE section). 760 76120120328: 762 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 763 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 764 now spelled mips. This is to aid compatibility with third-party 765 software that expects this naming scheme in uname(3). Little-endian 766 settings are unchanged. If you are updating a big-endian mips64 machine 767 from before this change, you may need to set MACHINE_ARCH=mips64 in 768 your environment before the new build system will recognize your machine. 769 77020120306: 771 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 772 platforms. 773 77420120229: 775 Now unix domain sockets behave "as expected" on nullfs(5). Previously 776 nullfs(5) did not pass through all behaviours to the underlying layer, 777 as a result if we bound to a socket on the lower layer we could connect 778 only to the lower path; if we bound to the upper layer we could connect 779 only to the upper path. The new behavior is one can connect to both the 780 lower and the upper paths regardless what layer path one binds to. 781 78220120211: 783 The getifaddrs upgrade path broken with 20111215 has been restored. 784 If you have upgraded in between 20111215 and 20120209 you need to 785 recompile libc again with your kernel. You still need to recompile 786 world to be able to configure CARP but this restriction already 787 comes from 20111215. 788 78920120114: 790 The set_rcvar() function has been removed from /etc/rc.subr. All 791 base and ports rc.d scripts have been updated, so if you have a 792 port installed with a script in /usr/local/etc/rc.d you can either 793 hand-edit the rcvar= line, or reinstall the port. 794 795 An easy way to handle the mass-update of /etc/rc.d: 796 rm /etc/rc.d/* && mergemaster -i 797 79820120109: 799 panic(9) now stops other CPUs in the SMP systems, disables interrupts 800 on the current CPU and prevents other threads from running. 801 This behavior can be reverted using the kern.stop_scheduler_on_panic 802 tunable/sysctl. 803 The new behavior can be incompatible with kern.sync_on_panic. 804 80520111215: 806 The carp(4) facility has been changed significantly. Configuration 807 of the CARP protocol via ifconfig(8) has changed, as well as format 808 of CARP events submitted to devd(8) has changed. See manual pages 809 for more information. The arpbalance feature of carp(4) is currently 810 not supported anymore. 811 812 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 813 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 814 need to be recompiled. 815 81620111122: 817 The acpi_wmi(4) status device /dev/wmistat has been renamed to 818 /dev/wmistat0. 819 82020111108: 821 The option VFS_ALLOW_NONMPSAFE option has been added in order to 822 explicitely support non-MPSAFE filesystems. 823 It is on by default for all supported platform at this present 824 time. 825 82620111101: 827 The broken amd(4) driver has been replaced with esp(4) in the amd64, 828 i386 and pc98 GENERIC kernel configuration files. 829 83020110930: 831 sysinstall has been removed 832 83320110923: 834 The stable/9 branch created in subversion. This corresponds to the 835 RELENG_9 branch in CVS. 836 83720110913: 838 This commit modifies vfs_register() so that it uses a hash 839 calculation to set vfc_typenum, which is enabled by default. 840 The first time a system is booted after this change, the 841 vfc_typenum values will change for all file systems. The 842 main effect of this is a change to the NFS server file handles 843 for file systems that use vfc_typenum in their fsid, such as ZFS. 844 It will, however, prevent vfc_typenum from changing when file 845 systems are loaded in a different order for subsequent reboots. 846 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 847 until you are ready to remount all NFS clients after a reboot. 848 84920110828: 850 Bump the shared library version numbers for libraries that 851 do not use symbol versioning, have changed the ABI compared 852 to stable/8 and which shared library version was not bumped. 853 Done as part of 9.0-RELEASE cycle. 854 85520110815: 856 During the merge of Capsicum features, the fget(9) KPI was modified. 857 This may require the rebuilding of out-of-tree device drivers -- 858 issues have been reported specifically with the nVidia device driver. 859 __FreeBSD_version is bumped to 900041. 860 861 Also, there is a period between 20110811 and 20110814 where the 862 special devices /dev/{stdin,stdout,stderr} did not work correctly. 863 Building world from a kernel during that window may not work. 864 86520110628: 866 The packet filter (pf) code has been updated to OpenBSD 4.5. 867 You need to update userland tools to be in sync with kernel. 868 This update breaks backward compatibility with earlier pfsync(4) 869 versions. Care must be taken when updating redundant firewall setups. 870 87120110608: 872 The following sysctls and tunables are retired on x86 platforms: 873 machdep.hlt_cpus 874 machdep.hlt_logical_cpus 875 The following sysctl is retired: 876 machdep.hyperthreading_allowed 877 The sysctls were supposed to provide a way to dynamically offline and 878 online selected CPUs on x86 platforms, but the implementation has not 879 been reliable especially with SCHED_ULE scheduler. 880 machdep.hyperthreading_allowed tunable is still available to ignore 881 hyperthreading CPUs at OS level. 882 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 883 where X is an APIC ID of a CPU. Be advised, though, that disabling 884 CPUs in non-uniform fashion will result in non-uniform topology and 885 may lead to sub-optimal system performance with SCHED_ULE, which is 886 a default scheduler. 887 88820110607: 889 cpumask_t type is retired and cpuset_t is used in order to describe 890 a mask of CPUs. 891 89220110531: 893 Changes to ifconfig(8) for dynamic address family detection mandate 894 that you are running a kernel of 20110525 or later. Make sure to 895 follow the update procedure to boot a new kernel before installing 896 world. 897 89820110513: 899 Support for sun4v architecture is officially dropped 900 90120110503: 902 Several KPI breaking changes have been committed to the mii(4) layer, 903 the PHY drivers and consequently some Ethernet drivers using mii(4). 904 This means that miibus.ko and the modules of the affected Ethernet 905 drivers need to be recompiled. 906 907 Note to kernel developers: Given that the OUI bit reversion problem 908 was fixed as part of these changes all mii(4) commits related to OUIs, 909 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 910 handling, no longer can be merged verbatim to stable/8 and previous 911 branches. 912 91320110430: 914 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 915 into their kernel configurations along with 'device pci'. 916 91720110427: 918 The default NFS client is now the new NFS client, so fstype "newnfs" 919 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 920 Although mounts via fstype "nfs" will usually work without userland 921 changes, it is recommended that the mount(8) and mount_nfs(8) 922 commands be rebuilt from sources and that a link to mount_nfs called 923 mount_oldnfs be created. The new client is compiled into the 924 kernel with "options NFSCL" and this is needed for diskless root 925 file systems. The GENERIC kernel configs have been changed to use 926 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 927 To use the regular/old client, you can "mount -t oldnfs ...". For 928 a diskless root file system, you must also include a line like: 929 930 vfs.root.mountfrom="oldnfs:" 931 932 in the boot/loader.conf on the root fs on the NFS server to make 933 a diskless root fs use the old client. 934 93520110424: 936 The GENERIC kernels for all architectures now default to the new 937 CAM-based ATA stack. It means that all legacy ATA drivers were 938 removed and replaced by respective CAM drivers. If you are using 939 ATA device names in /etc/fstab or other places, make sure to update 940 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 941 where 'Y's are the sequential numbers starting from zero for each type 942 in order of detection, unless configured otherwise with tunables, 943 see cam(4)). There will be symbolic links created in /dev/ to map 944 old adX devices to the respective adaY. They should provide basic 945 compatibility for file systems mounting in most cases, but they do 946 not support old user-level APIs and do not have respective providers 947 in GEOM. Consider using updated management tools with new device names. 948 949 It is possible to load devices ahci, ata, siis and mvs as modules, 950 but option ATA_CAM should remain in kernel configuration to make ata 951 module work as CAM driver supporting legacy ATA controllers. Device ata 952 still can be used in modular fashion (atacore + ...). Modules atadisk 953 and atapi* are not used and won't affect operation in ATA_CAM mode. 954 Note that to use CAM-based ATA kernel should include CAM devices 955 scbus, pass, da (or explicitly ada), cd and optionally others. All of 956 them are parts of the cam module. 957 958 ataraid(4) functionality is now supported by the RAID GEOM class. 959 To use it you can load geom_raid kernel module and use graid(8) tool 960 for management. Instead of /dev/arX device names, use /dev/raid/rX. 961 962 No kernel config options or code have been removed, so if a problem 963 arises, please report it and optionally revert to the old ATA stack. 964 In order to do it you can remove from the kernel config: 965 options ATA_CAM 966 device ahci 967 device mvs 968 device siis 969 , and instead add back: 970 device atadisk # ATA disk drives 971 device ataraid # ATA RAID drives 972 device atapicd # ATAPI CDROM drives 973 device atapifd # ATAPI floppy drives 974 device atapist # ATAPI tape drives 975 97620110423: 977 The default NFS server has been changed to the new server, which 978 was referred to as the experimental server. If you need to switch 979 back to the old NFS server, you must now put the "-o" option on 980 both the mountd and nfsd commands. This can be done using the 981 mountd_flags and nfs_server_flags rc.conf variables until an 982 update to the rc scripts is committed, which is coming soon. 983 98420110418: 985 The GNU Objective-C runtime library (libobjc), and other Objective-C 986 related components have been removed from the base system. If you 987 require an Objective-C library, please use one of the available ports. 988 98920110331: 990 ath(4) has been split into bus- and device- modules. if_ath contains 991 the HAL, the TX rate control and the network device code. if_ath_pci 992 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 993 contains the AHB glue. Users need to load both if_ath_pci and if_ath 994 in order to use ath on everything else. 995 996 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 997 need to load if_ath and if_ath_pci for ath(4) operation. 998 99920110314: 1000 As part of the replacement of sysinstall, the process of building 1001 release media has changed significantly. For details, please re-read 1002 release(7), which has been updated to reflect the new build process. 1003 100420110218: 1005 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1006 is the last available version under GPLv2. It brings a number of new 1007 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1008 4.1 and SSE 4.2), better support for powerpc64, a number of new 1009 directives, and lots of other small improvements. See the ChangeLog 1010 file in contrib/binutils for the full details. 1011 101220110218: 1013 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1014 compliant, and will now use half of hash for authentication. 1015 This will break interoperability with all stacks (including all 1016 actual FreeBSD versions) who implement 1017 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1018 authentication). 1019 The only workaround with such peers is to use another HMAC 1020 algorithm for IPsec ("phase 2") authentication. 1021 102220110207: 1023 Remove the uio_yield prototype and symbol. This function has 1024 been misnamed since it was introduced and should not be 1025 globally exposed with this name. The equivalent functionality 1026 is now available using kern_yield(curthread->td_user_pri). 1027 The function remains undocumented. 1028 102920110112: 1030 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1031 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1032 for scalar sysctls is defined but disabled. Code that needs 1033 UQUAD to pass the type checking that must compile on older 1034 systems where the define is not present can check against 1035 __FreeBSD_version >= 900030. 1036 1037 The system dialog(1) has been replaced with a new version previously 1038 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1039 with the previous version, but the libdialog associated with it has 1040 a largely incompatible API. As such, the original version of libdialog 1041 will be kept temporarily as libodialog, until its base system consumers 1042 are replaced or updated. Bump __FreeBSD_version to 900030. 1043 104420110103: 1045 If you are trying to run make universe on a -stable system, and you get 1046 the following warning: 1047 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1048 unknown. config(8) likely too old." 1049 or something similar to it, then you must upgrade your -stable system 1050 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1051 stable/8) or build the config from the latest stable/8 branch and 1052 install it on your system. 1053 1054 Prior to this date, building a current universe on 8-stable system from 1055 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1056 error in the first kernel build phase. A new config on those old 1057 systems will fix that problem for older versions of -current. 1058 105920101228: 1060 The TCP stack has been modified to allow Khelp modules to interact with 1061 it via helper hook points and store per-connection data in the TCP 1062 control block. Bump __FreeBSD_version to 900029. User space tools that 1063 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1064 be recompiled. 1065 106620101114: 1067 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1068 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1069 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1070 to take advantage of it instead of using custom implementations. This 1071 means that these drivers now no longer unconditionally advertise 1072 support for flow control but only do so if flow control is a selected 1073 media option. This was implemented in the generic support that way in 1074 order to allow flow control to be switched on and off via ifconfig(8) 1075 with the PHY specific default to typically off in order to protect 1076 from unwanted effects. Consequently, if you used flow control with 1077 one of the above mentioned drivers you now need to explicitly enable 1078 it, for example via: 1079 ifconfig bge0 media auto mediaopt flowcontrol 1080 1081 Along with the above mentioned changes generic support for setting 1082 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1083 e1000phy(4) as well as ip1000phy(4) have been converted to take 1084 advantage of it. This means that these drivers now no longer take the 1085 link0 parameter for selecting master mode but the master media option 1086 has to be used instead, for example like in the following: 1087 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1088 1089 Selection of master mode now is also available with all other PHY 1090 drivers supporting 1000baseT. 1091 109220101111: 1093 The TCP stack has received a significant update to add support for 1094 modularised congestion control and generally improve the clarity of 1095 congestion control decisions. Bump __FreeBSD_version to 900025. User 1096 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1097 sockstat) need to be recompiled. 1098 109920101002: 1100 The man(1) utility has been replaced by a new version that no longer 1101 uses /etc/manpath.config. Please consult man.conf(5) for how to 1102 migrate local entries to the new format. 1103 110420100928: 1105 The copyright strings printed by login(1) and sshd(8) at the time of a 1106 new connection have been removed to follow other operating systems and 1107 upstream sshd. 1108 110920100915: 1110 A workaround for a fixed ld bug has been removed in kernel code, 1111 so make sure that your system ld is built from sources after 1112 revision 210245 from 2010-07-19 (r211583 if building head kernel 1113 on stable/8, r211584 for stable/7; both from 2010-08-21). 1114 A symptom of incorrect ld version is different addresses for 1115 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1116 111720100913: 1118 The $ipv6_prefer variable in rc.conf(5) has been split into 1119 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1120 1121 The $ip6addrctl_policy is a variable to choose a pre-defined 1122 address selection policy set by ip6addrctl(8). A value 1123 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1124 default is "AUTO". 1125 1126 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1127 flag (see an entry of 20090926) is set on an interface with no 1128 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1129 security reason. If you want IPv6 link-local address on all 1130 interfaces by default, set this to "YES". 1131 1132 The old ipv6_prefer="YES" is equivalent to 1133 ipv6_activate_all_interfaces="YES" and 1134 ip6addrctl_policy="ipv6_prefer". 1135 113620100913: 1137 DTrace has grown support for userland tracing. Due to this, DTrace is 1138 now i386 and amd64 only. 1139 dtruss(1) is now installed by default on those systems and a new 1140 kernel module is needed for userland tracing: fasttrap. 1141 No changes to your kernel config file are necessary to enable 1142 userland tracing, but you might consider adding 'STRIP=' and 1143 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1144 to have informative userland stack traces in DTrace (ustack). 1145 114620100725: 1147 The acpi_aiboost(4) driver has been removed in favor of the new 1148 aibs(4) driver. You should update your kernel configuration file. 1149 115020100722: 1151 BSD grep has been imported to the base system and it is built by 1152 default. It is completely BSD licensed, highly GNU-compatible, uses 1153 less memory than its GNU counterpart and has a small codebase. 1154 However, it is slower than its GNU counterpart, which is mostly 1155 noticeable for larger searches, for smaller ones it is measurable 1156 but not significant. The reason is complex, the most important factor 1157 is that we lack a modern and efficient regex library and GNU 1158 overcomes this by optimizing the searches internally. Future work 1159 on improving the regex performance is planned, for the meantime, 1160 users that need better performance, can build GNU grep instead by 1161 setting the WITH_GNU_GREP knob. 1162 116320100713: 1164 Due to the import of powerpc64 support, all existing powerpc kernel 1165 configuration files must be updated with a machine directive like this: 1166 machine powerpc powerpc 1167 1168 In addition, an updated config(8) is required to build powerpc kernels 1169 after this change. 1170 117120100713: 1172 A new version of ZFS (version 15) has been merged to -HEAD. 1173 This version uses a python library for the following subcommands: 1174 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1175 For full functionality of these commands the following port must 1176 be installed: sysutils/py-zfs 1177 117820100429: 1179 'vm_page's are now hashed by physical address to an array of mutexes. 1180 Currently this is only used to serialize access to hold_count. Over 1181 time the page queue mutex will be peeled away. This changes the size 1182 of pmap on every architecture. And requires all callers of vm_page_hold 1183 and vm_page_unhold to be updated. 1184 118520100402: 1186 WITH_CTF can now be specified in src.conf (not recommended, there 1187 are some problems with static executables), make.conf (would also 1188 affect ports which do not use GNU make and do not override the 1189 compile targets) or in the kernel config (via "makeoptions 1190 WITH_CTF=yes"). 1191 When WITH_CTF was specified there before this was silently ignored, 1192 so make sure that WITH_CTF is not used in places which could lead 1193 to unwanted behavior. 1194 119520100311: 1196 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1197 to allow 32-bit compatibility on non-x86 platforms. All kernel 1198 configurations on amd64 and ia64 platforms using these options must 1199 be modified accordingly. 1200 120120100113: 1202 The utmp user accounting database has been replaced with utmpx, 1203 the user accounting interface standardized by POSIX. 1204 Unfortunately the semantics of utmp and utmpx don't match, 1205 making it practically impossible to support both interfaces. 1206 The user accounting database is used by tools like finger(1), 1207 last(1), talk(1), w(1) and ac(8). 1208 1209 All applications in the base system use utmpx. This means only 1210 local binaries (e.g. from the ports tree) may still use these 1211 utmp database files. These applications must be rebuilt to make 1212 use of utmpx. 1213 1214 After the system has been upgraded, it is safe to remove the old 1215 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1216 assuming their contents is of no importance anymore. Old wtmp 1217 databases can only be used by last(1) and ac(8) after they have 1218 been converted to the new format using wtmpcvt(1). 1219 122020100108: 1221 Introduce the kernel thread "deadlock resolver" (which can be enabled 1222 via the DEADLKRES option, see NOTES for more details) and the 1223 sleepq_type() function for sleepqueues. 1224 122520091202: 1226 The rc.firewall and rc.firewall6 were unified, and 1227 rc.firewall6 and rc.d/ip6fw were removed. 1228 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1229 variables are obsoleted. Instead, the following new rc 1230 variables are added to rc.d/ipfw: 1231 1232 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1233 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1234 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1235 1236 The meanings correspond to the relevant IPv4 variables. 1237 123820091125: 1239 8.0-RELEASE. 1240 124120091113: 1242 The default terminal emulation for syscons(4) has been changed 1243 from cons25 to xterm on all platforms except pc98. This means 1244 that the /etc/ttys file needs to be updated to ensure correct 1245 operation of applications on the console. 1246 1247 The terminal emulation style can be toggled per window by using 1248 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1249 options can be used to change the compile-time default back to 1250 cons25. 1251 1252 To prevent graphical artifacts, make sure the TERM environment 1253 variable is set to match the terminal emulation that is being 1254 performed by syscons(4). 1255 125620091109: 1257 The layout of the structure ieee80211req_scan_result has changed. 1258 Applications that require wireless scan results (e.g. ifconfig(8)) 1259 from net80211 need to be recompiled. 1260 1261 Applications such as wpa_supplicant(8) may require a full world 1262 build without using NO_CLEAN in order to get synchronized with the 1263 new structure. 1264 126520091025: 1266 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1267 There's one kernel module for each firmware. Adding "device iwnfw" 1268 to the kernel configuration file means including all three firmware 1269 images inside the kernel. If you want to include just the one for 1270 your wireless card, use the devices iwn4965fw, iwn5000fw or 1271 iwn5150fw. 1272 127320090926: 1274 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1275 into rc.d/netif. The changes are the following: 1276 1277 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1278 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1279 Note that both variables need the "inet6" keyword at the head. 1280 1281 Do not set $ipv6_network_interfaces manually if you do not 1282 understand what you are doing. It is not needed in most cases. 1283 1284 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1285 they are obsolete. 1286 1287 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1288 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1289 1290 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1291 all configured interfaces have "inet6 accept_rtadv" in the 1292 $ifconfig_IF_ipv6. These are for backward compatibility. 1293 1294 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1295 functionality of interfaces with no corresponding 1296 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1297 and the default address selection policy of ip6addrctl(8) 1298 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1299 Note that if you want to configure IPv6 functionality on the 1300 disabled interfaces after boot, first you need to clear the flag by 1301 using ifconfig(8) like: 1302 1303 ifconfig em0 inet6 -ifdisabled 1304 1305 If YES, the default address selection policy is set as 1306 IPv6-preferred. 1307 1308 The default value of $ipv6_prefer is NO. 1309 1310 4. If your system need to receive Router Advertisement messages, 1311 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1312 scripts automatically invoke rtsol(8) when the interface becomes 1313 UP. The Router Advertisement messages are used for SLAAC 1314 (State-Less Address AutoConfiguration). 1315 131620090922: 1317 802.11s D3.03 support was committed. This is incompatible with the 1318 previous code, which was based on D3.0. 1319 132020090912: 1321 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1322 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1323 control whether accepting Router Advertisement messages or not. 1324 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1325 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1326 The ifconfig(8) utility now supports these flags. 1327 132820090910: 1329 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1330 mount(8) and -a option for df(1) to see them. 1331 133220090825: 1333 The old tunable hw.bus.devctl_disable has been superseded by 1334 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1335 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1336 is 1000. 1337 133820090813: 1339 Remove the option STOP_NMI. The default action is now to use NMI only 1340 for KDB via the newly introduced function stop_cpus_hard() and 1341 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1342 134320090803: 1344 The stable/8 branch created in subversion. This corresponds to the 1345 RELENG_8 branch in CVS. 1346 134720090719: 1348 Bump the shared library version numbers for all libraries that do not 1349 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1350 __FreeBSD_version to 800105. 1351 135220090714: 1353 Due to changes in the implementation of virtual network stack support, 1354 all network-related kernel modules must be recompiled. As this change 1355 breaks the ABI, bump __FreeBSD_version to 800104. 1356 135720090713: 1358 The TOE interface to the TCP syncache has been modified to remove 1359 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1360 The cxgb driver is the only TOE consumer affected by this change, and 1361 needs to be recompiled along with the kernel. As this change breaks 1362 the ABI, bump __FreeBSD_version to 800103. 1363 136420090712: 1365 Padding has been added to struct tcpcb, sackhint and tcpstat in 1366 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1367 maintaining the ABI. However, this change breaks the ABI, so bump 1368 __FreeBSD_version to 800102. User space tools that rely on the size of 1369 any of these structs (e.g. sockstat) need to be recompiled. 1370 137120090630: 1372 The NFS_LEGACYRPC option has been removed along with the old kernel 1373 RPC implementation that this option selected. Kernel configurations 1374 may need to be adjusted. 1375 137620090629: 1377 The network interface device nodes at /dev/net/<interface> have been 1378 removed. All ioctl operations can be performed the normal way using 1379 routing sockets. The kqueue functionality can generally be replaced 1380 with routing sockets. 1381 138220090628: 1383 The documentation from the FreeBSD Documentation Project (Handbook, 1384 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1385 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1386 138720090624: 1388 The ABI of various structures related to the SYSV IPC API have been 1389 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1390 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1391 800100. 1392 139320090622: 1394 Layout of struct vnet has changed as routing related variables were 1395 moved to their own Vimage module. Modules need to be recompiled. Bump 1396 __FreeBSD_version to 800099. 1397 139820090619: 1399 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1400 respectively. As long as no more than 16 groups per process are used, 1401 no changes should be visible. When more than 16 groups are used, old 1402 binaries may fail if they call getgroups() or getgrouplist() with 1403 statically sized storage. Recompiling will work around this, but 1404 applications should be modified to use dynamically allocated storage 1405 for group arrays as POSIX.1-2008 does not cap an implementation's 1406 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1407 1408 NFS and portalfs mounts may also be affected as the list of groups is 1409 truncated to 16. Users of NFS who use more than 16 groups, should 1410 take care that negative group permissions are not used on the exported 1411 file systems as they will not be reliable unless a GSSAPI based 1412 authentication method is used. 1413 141420090616: 1415 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1416 option compiles in the support for adaptive spinning for lockmgrs 1417 which want to enable it. The lockinit() function now accepts the flag 1418 LK_ADAPTIVE in order to make the lock object subject to adaptive 1419 spinning when both held in write and read mode. 1420 142120090613: 1422 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1423 changed. User applications that use this ioctl need to be rebuilt. 1424 142520090611: 1426 The layout of struct thread has changed. Kernel and modules need to 1427 be rebuilt. 1428 142920090608: 1430 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1431 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1432 143320090602: 1434 window(1) has been removed from the base system. It can now be 1435 installed from ports. The port is called misc/window. 1436 143720090601: 1438 The way we are storing and accessing `routing table' entries has 1439 changed. Programs reading the FIB, like netstat, need to be 1440 re-compiled. 1441 144220090601: 1443 A new netisr implementation has been added for FreeBSD 8. Network 1444 file system modules, such as igmp, ipdivert, and others, should be 1445 rebuilt. 1446 Bump __FreeBSD_version to 800096. 1447 144820090530: 1449 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1450 more valid. 1451 145220090530: 1453 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1454 Bump __FreeBSD_version to 800094. 1455 145620090529: 1457 Add mnt_xflag field to 'struct mount'. File system modules need to be 1458 rebuilt. 1459 Bump __FreeBSD_version to 800093. 1460 146120090528: 1462 The compiling option ADAPTIVE_SX has been retired while it has been 1463 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1464 The KPI for sx_init_flags() changes as accepting flags: 1465 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1466 been introduced in order to handle the reversed logic. 1467 Bump __FreeBSD_version to 800092. 1468 146920090527: 1470 Add support for hierarchical jails. Remove global securelevel. 1471 Bump __FreeBSD_version to 800091. 1472 147320090523: 1474 The layout of struct vnet_net has changed, therefore modules 1475 need to be rebuilt. 1476 Bump __FreeBSD_version to 800090. 1477 147820090523: 1479 The newly imported zic(8) produces a new format in the output. Please 1480 run tzsetup(8) to install the newly created data to /etc/localtime. 1481 148220090520: 1483 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1484 hw.usb.* and is now consistent again with previous releases. 1485 148620090520: 1487 802.11 monitor mode support was revised and driver api's were changed. 1488 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1489 of DLT_IEEE802_11. No user-visible data structures were changed but 1490 applications that use DLT_IEEE802_11 may require changes. 1491 Bump __FreeBSD_version to 800088. 1492 149320090430: 1494 The layout of the following structs has changed: sysctl_oid, 1495 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1496 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1497 panics may be experienced. World rebuild is required for 1498 correctly checking networking state from userland. 1499 Bump __FreeBSD_version to 800085. 1500 150120090429: 1502 MLDv2 and Source-Specific Multicast (SSM) have been merged 1503 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1504 The implementation of SSM within FreeBSD's IPv6 stack closely 1505 follows the IPv4 implementation. 1506 1507 For kernel developers: 1508 1509 * The most important changes are that the ip6_output() and 1510 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1511 and this lock has been downgraded to a non-recursive mutex. 1512 1513 * As with the changes to the IPv4 stack to support SSM, filtering 1514 of inbound multicast traffic must now be performed by transport 1515 protocols within the IPv6 stack. This does not apply to TCP and 1516 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1517 1518 * The KPIs used by IPv6 multicast are similar to those used by 1519 the IPv4 stack, with the following differences: 1520 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1521 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1522 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1523 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1524 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1525 for MLDv1 have an additional 'timer' argument which is used to 1526 jitter the initial membership report for the solicited-node 1527 multicast membership on-link. 1528 * This is not strictly needed for MLDv2, which already jitters 1529 its report transmissions. However, the 'timer' argument is 1530 preserved in case MLDv1 is active on the interface. 1531 1532 * The KAME linked-list based IPv6 membership implementation has 1533 been refactored to use a vector similar to that used by the IPv4 1534 stack. 1535 Code which maintains a list of its own multicast memberships 1536 internally, e.g. carp, has been updated to reflect the new 1537 semantics. 1538 1539 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1540 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1541 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1542 implementation constraint which needs to be addressed in HEAD. 1543 1544 For application developers: 1545 1546 * The changes are broadly similar to those made for the IPv4 1547 stack. 1548 1549 * The use of IPv4 and IPv6 multicast socket options on the same 1550 socket, using mapped addresses, HAS NOT been tested or supported. 1551 1552 * There are a number of issues with the implementation of various 1553 IPv6 multicast APIs which need to be resolved in the API surface 1554 before the implementation is fully compatible with KAME userland 1555 use, and these are mostly to do with interface index treatment. 1556 1557 * The literature available discusses the use of either the delta / ASM 1558 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1559 using setsourcefilter(3)/getsourcefilter(3). For more information 1560 please refer to RFC 3768, 'Socket Interface Extensions for 1561 Multicast Source Filters'. 1562 1563 * Applications which use the published RFC 3678 APIs should be fine. 1564 1565 For systems administrators: 1566 1567 * The mtest(8) utility has been refactored to support IPv6, in 1568 addition to IPv4. Interface addresses are no longer accepted 1569 as arguments, their names must be used instead. The utility 1570 will map the interface name to its first IPv4 address as 1571 returned by getifaddrs(3). 1572 1573 * The ifmcstat(8) utility has also been updated to print the MLDv2 1574 endpoint state and source filter lists via sysctl(3). 1575 1576 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1577 loopback of IPv6 multicast datagrams by default; it defaults to 1 1578 to preserve the existing behaviour. Disabling multicast loopback is 1579 recommended for optimal system performance. 1580 1581 * The IPv6 MROUTING code has been changed to examine this sysctl 1582 instead of attempting to perform a group lookup before looping 1583 back forwarded datagrams. 1584 1585 Bump __FreeBSD_version to 800084. 1586 158720090422: 1588 Implement low-level Bluetooth HCI API. 1589 Bump __FreeBSD_version to 800083. 1590 159120090419: 1592 The layout of struct malloc_type, used by modules to register new 1593 memory allocation types, has changed. Most modules will need to 1594 be rebuilt or panics may be experienced. 1595 Bump __FreeBSD_version to 800081. 1596 159720090415: 1598 Anticipate overflowing inp_flags - add inp_flags2. 1599 This changes most offsets in inpcb, so checking v4 connection 1600 state will require a world rebuild. 1601 Bump __FreeBSD_version to 800080. 1602 160320090415: 1604 Add an llentry to struct route and struct route_in6. Modules 1605 embedding a struct route will need to be recompiled. 1606 Bump __FreeBSD_version to 800079. 1607 160820090414: 1609 The size of rt_metrics_lite and by extension rtentry has changed. 1610 Networking administration apps will need to be recompiled. 1611 The route command now supports show as an alias for get, weighting 1612 of routes, sticky and nostick flags to alter the behavior of stateful 1613 load balancing. 1614 Bump __FreeBSD_version to 800078. 1615 161620090408: 1617 Do not use Giant for kbdmux(4) locking. This is wrong and 1618 apparently causing more problems than it solves. This will 1619 re-open the issue where interrupt handlers may race with 1620 kbdmux(4) in polling mode. Typical symptoms include (but 1621 not limited to) duplicated and/or missing characters when 1622 low level console functions (such as gets) are used while 1623 interrupts are enabled (for example geli password prompt, 1624 mountroot prompt etc.). Disabling kbdmux(4) may help. 1625 162620090407: 1627 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1628 kernel modules referencing any of the above need to be recompiled. 1629 Bump __FreeBSD_version to 800075. 1630 163120090320: 1632 GEOM_PART has become the default partition slicer for storage devices, 1633 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1634 introduces some changes: 1635 1636 MSDOS/EBR: the devices created from MSDOS extended partition entries 1637 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1638 to devices with offset-based names. fstabs may need to be modified. 1639 1640 BSD: the "geometry does not match label" warning is harmless in most 1641 cases but it points to problems in file system misalignment with 1642 disk geometry. The "c" partition is now implicit, covers the whole 1643 top-level drive and cannot be (mis)used by users. 1644 1645 General: Kernel dumps are now not allowed to be written to devices 1646 whose partition types indicate they are meant to be used for file 1647 systems (or, in case of MSDOS partitions, as something else than 1648 the "386BSD" type). 1649 1650 Most of these changes date approximately from 200812. 1651 165220090319: 1653 The uscanner(4) driver has been removed from the kernel. This follows 1654 Linux removing theirs in 2.6 and making libusb the default interface 1655 (supported by sane). 1656 165720090319: 1658 The multicast forwarding code has been cleaned up. netstat(1) 1659 only relies on KVM now for printing bandwidth upcall meters. 1660 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1661 ip6_mroute_mod respectively. The config(5) options for statically 1662 compiling this code remain the same, i.e. 'options MROUTING'. 1663 166420090315: 1665 Support for the IFF_NEEDSGIANT network interface flag has been 1666 removed, which means that non-MPSAFE network device drivers are no 1667 longer supported. In particular, if_ar, if_sr, and network device 1668 drivers from the old (legacy) USB stack can no longer be built or 1669 used. 1670 167120090313: 1672 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1673 a bunch of new language catalog files have also been added. 1674 This means that some common libc messages are now localized and 1675 they depend on the LC_MESSAGES environmental variable. 1676 167720090313: 1678 The k8temp(4) driver has been renamed to amdtemp(4) since 1679 support for Family 10 and Family 11 CPU families was added. 1680 168120090309: 1682 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1683 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1684 1685 For kernel developers, the most important changes are that the 1686 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1687 and this lock has been downgraded to a non-recursive mutex. 1688 1689 Transport protocols (UDP, Raw IP) are now responsible for filtering 1690 inbound multicast traffic according to group membership and source 1691 filters. The imo_multicast_filter() KPI exists for this purpose. 1692 Transports which do not use multicast (SCTP, TCP) already reject 1693 multicast by default. Forwarding and receive performance may improve 1694 as a mutex acquisition is no longer needed in the ip_input() 1695 low-level input path. in_addmulti() and in_delmulti() are shimmed 1696 to new KPIs which exist to support SSM in-kernel. 1697 1698 For application developers, it is recommended that loopback of 1699 multicast datagrams be disabled for best performance, as this 1700 will still cause the lock to be taken for each looped-back 1701 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1702 be tuned to 0 to disable loopback by default; it defaults to 1 1703 to preserve the existing behaviour. 1704 1705 For systems administrators, to obtain best performance with 1706 multicast reception and multiple groups, it is always recommended 1707 that a card with a suitably precise hash filter is used. Hash 1708 collisions will still result in the lock being taken within the 1709 transport protocol input path to check group membership. 1710 1711 If deploying FreeBSD in an environment with IGMP snooping switches, 1712 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1713 enabled; this forces 224.0.0.0/24 group membership to be announced 1714 via IGMP. 1715 1716 The size of 'struct igmpstat' has changed; netstat needs to be 1717 recompiled to reflect this. 1718 Bump __FreeBSD_version to 800070. 1719 172020090309: 1721 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1722 updated to use it. This requires a buildworld/installworld in order to 1723 update the library and dependencies (usbconfig, etc). Its advisable to 1724 rebuild all ports which uses libusb. More specific directions are given 1725 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1726 libusb are no longer required and can be removed. 1727 172820090302: 1729 A workaround is committed to allow the creation of System V shared 1730 memory segment of size > 2 GB on the 64-bit architectures. 1731 Due to a limitation of the existing ABI, the shm_segsz member 1732 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1733 wrong for large segments. Note that limits must be explicitly 1734 raised to allow such segments to be created. 1735 173620090301: 1737 The layout of struct ifnet has changed, requiring a rebuild of all 1738 network device driver modules. 1739 174020090227: 1741 The /dev handling for the new USB stack has changed, a 1742 buildworld/installworld is required for libusb20. 1743 174420090223: 1745 The new USB2 stack has now been permanently moved in and all kernel and 1746 module names reverted to their previous values (eg, usb, ehci, ohci, 1747 ums, ...). The old usb stack can be compiled in by prefixing the name 1748 with the letter 'o', the old usb modules have been removed. 1749 Updating entry 20090216 for xorg and 20090215 for libmap may still 1750 apply. 1751 175220090217: 1753 The rc.conf(5) option if_up_delay has been renamed to 1754 defaultroute_delay to better reflect its purpose. If you have 1755 customized this setting in /etc/rc.conf you need to update it to 1756 use the new name. 1757 175820090216: 1759 xorg 7.4 wants to configure its input devices via hald which does not 1760 yet work with USB2. If the keyboard/mouse does not work in xorg then 1761 add 1762 Option "AllowEmptyInput" "off" 1763 to your ServerLayout section. This will cause X to use the configured 1764 kbd and mouse sections from your xorg.conf. 1765 176620090215: 1767 The GENERIC kernels for all architectures now default to the new USB2 1768 stack. No kernel config options or code have been removed so if a 1769 problem arises please report it and optionally revert to the old USB 1770 stack. If you are loading USB kernel modules or have a custom kernel 1771 that includes GENERIC then ensure that usb names are also changed over, 1772 eg uftdi -> usb2_serial_ftdi. 1773 1774 Older programs linked against the ports libusb 0.1 need to be 1775 redirected to the new stack's libusb20. /etc/libmap.conf can 1776 be used for this: 1777 # Map old usb library to new one for usb2 stack 1778 libusb-0.1.so.8 libusb20.so.1 1779 178020090209: 1781 All USB ethernet devices now attach as interfaces under the name ueN 1782 (eg. ue0). This is to provide a predictable name as vendors often 1783 change usb chipsets in a product without notice. 1784 178520090203: 1786 The ichsmb(4) driver has been changed to require SMBus slave 1787 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1788 All of the other SMBus controller drivers require left-justified 1789 slave addresses, so this change makes all the drivers provide the 1790 same interface. 1791 179220090201: 1793 INET6 statistics (struct ip6stat) was updated. 1794 netstat(1) needs to be recompiled. 1795 179620090119: 1797 NTFS has been removed from GENERIC kernel on amd64 to match 1798 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1799 will load ntfs.ko module automatically when NTFS support is 1800 actually needed, unless ntfs.ko is not installed or security 1801 level prohibits loading kernel modules. If either is the case, 1802 "options NTFS" has to be added into kernel config. 1803 180420090115: 1805 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1806 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1807 800061. User space tools that rely on the size of struct tcpcb in 1808 tcp_var.h (e.g. sockstat) need to be recompiled. 1809 181020081225: 1811 ng_tty(4) module updated to match the new TTY subsystem. 1812 Due to API change, user-level applications must be updated. 1813 New API support added to mpd5 CVS and expected to be present 1814 in next mpd5.3 release. 1815 181620081219: 1817 With __FreeBSD_version 800060 the makefs tool is part of 1818 the base system (it was a port). 1819 182020081216: 1821 The afdata and ifnet locks have been changed from mutexes to 1822 rwlocks, network modules will need to be re-compiled. 1823 182420081214: 1825 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1826 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1827 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1828 architecture and 40 bytes on 64-bit architecture. The userland 1829 applications "arp" and "ndp" have been updated accordingly. 1830 The output from "netstat -r" shows only routing entries and 1831 none of the L2 information. 1832 183320081130: 1834 __FreeBSD_version 800057 marks the switchover from the 1835 binary ath hal to source code. Users must add the line: 1836 1837 options AH_SUPPORT_AR5416 1838 1839 to their kernel config files when specifying: 1840 1841 device ath_hal 1842 1843 The ath_hal module no longer exists; the code is now compiled 1844 together with the driver in the ath module. It is now 1845 possible to tailor chip support (i.e. reduce the set of chips 1846 and thereby the code size); consult ath_hal(4) for details. 1847 184820081121: 1849 __FreeBSD_version 800054 adds memory barriers to 1850 <machine/atomic.h>, new interfaces to ifnet to facilitate 1851 multiple hardware transmit queues for cards that support 1852 them, and a lock-less ring-buffer implementation to 1853 enable drivers to more efficiently manage queueing of 1854 packets. 1855 185620081117: 1857 A new version of ZFS (version 13) has been merged to -HEAD. 1858 This version has zpool attribute "listsnapshots" off by 1859 default, which means "zfs list" does not show snapshots, 1860 and is the same as Solaris behavior. 1861 186220081028: 1863 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1864 186520081009: 1866 The uhci, ohci, ehci and slhci USB Host controller drivers have 1867 been put into separate modules. If you load the usb module 1868 separately through loader.conf you will need to load the 1869 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1870 controller add the following to loader.conf: 1871 1872 uhci_load="YES" 1873 ehci_load="YES" 1874 187520081009: 1876 The ABI used by the PMC toolset has changed. Please keep 1877 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1878 sync. 1879 188020081009: 1881 atapci kernel module now includes only generic PCI ATA 1882 driver. AHCI driver moved to ataahci kernel module. 1883 All vendor-specific code moved into separate kernel modules: 1884 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1885 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1886 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1887 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1888 188920080820: 1890 The TTY subsystem of the kernel has been replaced by a new 1891 implementation, which provides better scalability and an 1892 improved driver model. Most common drivers have been migrated to 1893 the new TTY subsystem, while others have not. The following 1894 drivers have not yet been ported to the new TTY layer: 1895 1896 PCI/ISA: 1897 cy, digi, rc, rp, sio 1898 1899 USB: 1900 ubser, ucycom 1901 1902 Line disciplines: 1903 ng_h4, ng_tty, ppp, sl, snp 1904 1905 Adding these drivers to your kernel configuration file shall 1906 cause compilation to fail. 1907 190820080818: 1909 ntpd has been upgraded to 4.2.4p5. 1910 191120080801: 1912 OpenSSH has been upgraded to 5.1p1. 1913 1914 For many years, FreeBSD's version of OpenSSH preferred DSA 1915 over RSA for host and user authentication keys. With this 1916 upgrade, we've switched to the vendor's default of RSA over 1917 DSA. This may cause upgraded clients to warn about unknown 1918 host keys even for previously known hosts. Users should 1919 follow the usual procedure for verifying host keys before 1920 accepting the RSA key. 1921 1922 This can be circumvented by setting the "HostKeyAlgorithms" 1923 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1924 command line. 1925 1926 Please note that the sequence of keys offered for 1927 authentication has been changed as well. You may want to 1928 specify IdentityFile in a different order to revert this 1929 behavior. 1930 193120080713: 1932 The sio(4) driver has been removed from the i386 and amd64 1933 kernel configuration files. This means uart(4) is now the 1934 default serial port driver on those platforms as well. 1935 1936 To prevent collisions with the sio(4) driver, the uart(4) driver 1937 uses different names for its device nodes. This means the 1938 onboard serial port will now most likely be called "ttyu0" 1939 instead of "ttyd0". You may need to reconfigure applications to 1940 use the new device names. 1941 1942 When using the serial port as a boot console, be sure to update 1943 /boot/device.hints and /etc/ttys before booting the new kernel. 1944 If you forget to do so, you can still manually specify the hints 1945 at the loader prompt: 1946 1947 set hint.uart.0.at="isa" 1948 set hint.uart.0.port="0x3F8" 1949 set hint.uart.0.flags="0x10" 1950 set hint.uart.0.irq="4" 1951 boot -s 1952 195320080609: 1954 The gpt(8) utility has been removed. Use gpart(8) to partition 1955 disks instead. 1956 195720080603: 1958 The version that Linuxulator emulates was changed from 2.4.2 1959 to 2.6.16. If you experience any problems with Linux binaries 1960 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1961 if it fixes the problem contact emulation mailing list. 1962 196320080525: 1964 ISDN4BSD (I4B) was removed from the src tree. You may need to 1965 update a your kernel configuration and remove relevant entries. 1966 196720080509: 1968 I have checked in code to support multiple routing tables. 1969 See the man pages setfib(1) and setfib(2). 1970 This is a hopefully backwards compatible version, 1971 but to make use of it you need to compile your kernel 1972 with options ROUTETABLES=2 (or more up to 16). 1973 197420080420: 1975 The 802.11 wireless support was redone to enable multi-bss 1976 operation on devices that are capable. The underlying device 1977 is no longer used directly but instead wlanX devices are 1978 cloned with ifconfig. This requires changes to rc.conf files. 1979 For example, change: 1980 ifconfig_ath0="WPA DHCP" 1981 to 1982 wlans_ath0=wlan0 1983 ifconfig_wlan0="WPA DHCP" 1984 see rc.conf(5) for more details. In addition, mergemaster of 1985 /etc/rc.d is highly recommended. Simultaneous update of userland 1986 and kernel wouldn't hurt either. 1987 1988 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1989 modules were merged into the base wlan module. All references 1990 to these modules (e.g. in kernel config files) must be removed. 1991 199220080408: 1993 psm(4) has gained write(2) support in native operation level. 1994 Arbitrary commands can be written to /dev/psm%d and status can 1995 be read back from it. Therefore, an application is responsible 1996 for status validation and error recovery. It is a no-op in 1997 other operation levels. 1998 199920080312: 2000 Support for KSE threading has been removed from the kernel. To 2001 run legacy applications linked against KSE libmap.conf may 2002 be used. The following libmap.conf may be used to ensure 2003 compatibility with any prior release: 2004 2005 libpthread.so.1 libthr.so.1 2006 libpthread.so.2 libthr.so.2 2007 libkse.so.3 libthr.so.3 2008 200920080301: 2010 The layout of struct vmspace has changed. This affects libkvm 2011 and any executables that link against libkvm and use the 2012 kvm_getprocs() function. In particular, but not exclusively, 2013 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2014 The effects are minimal, but it's advisable to upgrade world 2015 nonetheless. 2016 201720080229: 2018 The latest em driver no longer has support in it for the 2019 82575 adapter, this is now moved to the igb driver. The 2020 split was done to make new features that are incompatible 2021 with older hardware easier to do. 2022 202320080220: 2024 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2025 likewise the kernel option is now GEOM_LINUX_LVM. 2026 202720080211: 2028 The default NFS mount mode has changed from UDP to TCP for 2029 increased reliability. If you rely on (insecurely) NFS 2030 mounting across a firewall you may need to update your 2031 firewall rules. 2032 203320080208: 2034 Belatedly note the addition of m_collapse for compacting 2035 mbuf chains. 2036 203720080126: 2038 The fts(3) structures have been changed to use adequate 2039 integer types for their members and so to be able to cope 2040 with huge file trees. The old fts(3) ABI is preserved 2041 through symbol versioning in libc, so third-party binaries 2042 using fts(3) should still work, although they will not take 2043 advantage of the extended types. At the same time, some 2044 third-party software might fail to build after this change 2045 due to unportable assumptions made in its source code about 2046 fts(3) structure members. Such software should be fixed 2047 by its vendor or, in the worst case, in the ports tree. 2048 FreeBSD_version 800015 marks this change for the unlikely 2049 case that a portable fix is impossible. 2050 205120080123: 2052 To upgrade to -current after this date, you must be running 2053 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2054 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2055 205620071128: 2057 The ADAPTIVE_GIANT kernel option has been retired because its 2058 functionality is the default now. 2059 206020071118: 2061 The AT keyboard emulation of sunkbd(4) has been turned on 2062 by default. In order to make the special symbols of the Sun 2063 keyboards driven by sunkbd(4) work under X these now have 2064 to be configured the same way as Sun USB keyboards driven 2065 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2066 2067 Option "XkbLayout" "us" 2068 Option "XkbRules" "xorg" 2069 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2070 207120071024: 2072 It has been decided that it is desirable to provide ABI 2073 backwards compatibility to the FreeBSD 4/5/6 versions of the 2074 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2075 broken with the introduction of PCI domain support (see the 2076 20070930 entry). Unfortunately, this required the ABI of 2077 PCIOCGETCONF to be broken again in order to be able to 2078 provide backwards compatibility to the old version of that 2079 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2080 again. As for prominent ports this affects neither pciutils 2081 nor xorg-server this time, the hal port needs to be rebuilt 2082 however. 2083 208420071020: 2085 The misnamed kthread_create() and friends have been renamed 2086 to kproc_create() etc. Many of the callers already 2087 used kproc_start().. 2088 I will return kthread_create() and friends in a while 2089 with implementations that actually create threads, not procs. 2090 Renaming corresponds with version 800002. 2091 209220071010: 2093 RELENG_7 branched. 2094 2095COMMON ITEMS: 2096 2097 General Notes 2098 ------------- 2099 Avoid using make -j when upgrading. While generally safe, there are 2100 sometimes problems using -j to upgrade. If your upgrade fails with 2101 -j, please try again without -j. From time to time in the past there 2102 have been problems using -j with buildworld and/or installworld. This 2103 is especially true when upgrading between "distant" versions (eg one 2104 that cross a major release boundary or several minor releases, or when 2105 several months have passed on the -current branch). 2106 2107 Sometimes, obscure build problems are the result of environment 2108 poisoning. This can happen because the make utility reads its 2109 environment when searching for values for global variables. To run 2110 your build attempts in an "environmental clean room", prefix all make 2111 commands with 'env -i '. See the env(1) manual page for more details. 2112 2113 When upgrading from one major version to another it is generally best 2114 to upgrade to the latest code in the currently installed branch first, 2115 then do an upgrade to the new branch. This is the best-tested upgrade 2116 path, and has the highest probability of being successful. Please try 2117 this approach before reporting problems with a major version upgrade. 2118 2119 When upgrading a live system, having a root shell around before 2120 installing anything can help undo problems. Not having a root shell 2121 around can lead to problems if pam has changed too much from your 2122 starting point to allow continued authentication after the upgrade. 2123 2124 ZFS notes 2125 --------- 2126 When upgrading the boot ZFS pool to a new version, always follow 2127 these two steps: 2128 2129 1.) recompile and reinstall the ZFS boot loader and boot block 2130 (this is part of "make buildworld" and "make installworld") 2131 2132 2.) update the ZFS boot block on your boot drive 2133 2134 The following example updates the ZFS boot block on the first 2135 partition (freebsd-boot) of a GPT partitioned drive ad0: 2136 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2137 2138 Non-boot pools do not need these updates. 2139 2140 To build a kernel 2141 ----------------- 2142 If you are updating from a prior version of FreeBSD (even one just 2143 a few days old), you should follow this procedure. It is the most 2144 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2145 2146 make kernel-toolchain 2147 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2148 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2149 2150 To test a kernel once 2151 --------------------- 2152 If you just want to boot a kernel once (because you are not sure 2153 if it works, or if you want to boot a known bad kernel to provide 2154 debugging information) run 2155 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2156 nextboot -k testkernel 2157 2158 To just build a kernel when you know that it won't mess you up 2159 -------------------------------------------------------------- 2160 This assumes you are already running a CURRENT system. Replace 2161 ${arch} with the architecture of your machine (e.g. "i386", 2162 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2163 2164 cd src/sys/${arch}/conf 2165 config KERNEL_NAME_HERE 2166 cd ../compile/KERNEL_NAME_HERE 2167 make depend 2168 make 2169 make install 2170 2171 If this fails, go to the "To build a kernel" section. 2172 2173 To rebuild everything and install it on the current system. 2174 ----------------------------------------------------------- 2175 # Note: sometimes if you are running current you gotta do more than 2176 # is listed here if you are upgrading from a really old current. 2177 2178 <make sure you have good level 0 dumps> 2179 make buildworld 2180 make kernel KERNCONF=YOUR_KERNEL_HERE 2181 [1] 2182 <reboot in single user> [3] 2183 mergemaster -p [5] 2184 make installworld 2185 mergemaster -i [4] 2186 make delete-old [6] 2187 <reboot> 2188 2189 To cross-install current onto a separate partition 2190 -------------------------------------------------- 2191 # In this approach we use a separate partition to hold 2192 # current's root, 'usr', and 'var' directories. A partition 2193 # holding "/", "/usr" and "/var" should be about 2GB in 2194 # size. 2195 2196 <make sure you have good level 0 dumps> 2197 <boot into -stable> 2198 make buildworld 2199 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2200 <maybe newfs current's root partition> 2201 <mount current's root partition on directory ${CURRENT_ROOT}> 2202 make installworld DESTDIR=${CURRENT_ROOT} 2203 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2204 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2205 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2206 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2207 <reboot into current> 2208 <do a "native" rebuild/install as described in the previous section> 2209 <maybe install compatibility libraries from ports/misc/compat*> 2210 <reboot> 2211 2212 2213 To upgrade in-place from stable to current 2214 ---------------------------------------------- 2215 <make sure you have good level 0 dumps> 2216 make buildworld [9] 2217 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2218 [1] 2219 <reboot in single user> [3] 2220 mergemaster -p [5] 2221 make installworld 2222 mergemaster -i [4] 2223 make delete-old [6] 2224 <reboot> 2225 2226 Make sure that you've read the UPDATING file to understand the 2227 tweaks to various things you need. At this point in the life 2228 cycle of current, things change often and you are on your own 2229 to cope. The defaults can also change, so please read ALL of 2230 the UPDATING entries. 2231 2232 Also, if you are tracking -current, you must be subscribed to 2233 freebsd-current@freebsd.org. Make sure that before you update 2234 your sources that you have read and understood all the recent 2235 messages there. If in doubt, please track -stable which has 2236 much fewer pitfalls. 2237 2238 [1] If you have third party modules, such as vmware, you 2239 should disable them at this point so they don't crash your 2240 system on reboot. 2241 2242 [3] From the bootblocks, boot -s, and then do 2243 fsck -p 2244 mount -u / 2245 mount -a 2246 cd src 2247 adjkerntz -i # if CMOS is wall time 2248 Also, when doing a major release upgrade, it is required that 2249 you boot into single user mode to do the installworld. 2250 2251 [4] Note: This step is non-optional. Failure to do this step 2252 can result in a significant reduction in the functionality of the 2253 system. Attempting to do it by hand is not recommended and those 2254 that pursue this avenue should read this file carefully, as well 2255 as the archives of freebsd-current and freebsd-hackers mailing lists 2256 for potential gotchas. The -U option is also useful to consider. 2257 See mergemaster(8) for more information. 2258 2259 [5] Usually this step is a noop. However, from time to time 2260 you may need to do this if you get unknown user in the following 2261 step. It never hurts to do it all the time. You may need to 2262 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2263 install) after the buildworld before this step if you last updated 2264 from current before 20130425 or from -stable before 20130430. 2265 2266 [6] This only deletes old files and directories. Old libraries 2267 can be deleted by "make delete-old-libs", but you have to make 2268 sure that no program is using those libraries anymore. 2269 2270 [8] In order to have a kernel that can run the 4.x binaries needed to 2271 do an installworld, you must include the COMPAT_FREEBSD4 option in 2272 your kernel. Failure to do so may leave you with a system that is 2273 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2274 required to run the 5.x binaries on more recent kernels. And so on 2275 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2276 2277 Make sure that you merge any new devices from GENERIC since the 2278 last time you updated your kernel config file. 2279 2280 [9] When checking out sources, you must include the -P flag to have 2281 cvs prune empty directories. 2282 2283 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2284 "?=" instead of the "=" assignment operator, so that buildworld can 2285 override the CPUTYPE if it needs to. 2286 2287 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2288 not on the command line, or in /etc/make.conf. buildworld will 2289 warn if it is improperly defined. 2290FORMAT: 2291 2292This file contains a list, in reverse chronological order, of major 2293breakages in tracking -current. It is not guaranteed to be a complete 2294list of such breakages, and only contains entries since October 10, 2007. 2295If you need to see UPDATING entries from before that date, you will need 2296to fetch an UPDATING file from an older FreeBSD release. 2297 2298Copyright information: 2299 2300Copyright 1998-2009 M.
