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 1920160811 p7 FreeBSD-EN-16:10.dhclient 20 FreeBSD-EN-16:11.vmbus 21 FreeBSD-EN-16:12.hv_storvsc 22 FreeBSD-EN-16:13.vmbus 23 FreeBSD-EN-16:14.hv_storvsc 24 FreeBSD-EN-16:15.vmbus 25 FreeBSD-EN-16:16.hv_storvsc 26 27 Fix handling of unknown options from a DHCP server.

They are 85 still available in the security/openssh-portable port. 86 8720151214: 88 r292223 changed the internal interface between the nfsd.ko and 89 nfscommon.ko modules. As such, they must both be upgraded to-gether. 90 __FreeBSD_version has been bumped because of this. 91 9220151113: 93 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 94 Kernel modules isp_2400_multi and isp_2500_multi were removed and 95 should be replaced with isp_2400 and isp_2500 modules respectively. 96 9720150806: 98 The menu.rc and loader.rc files will now be replaced during 99 upgrades. Please migrate local changes to menu.rc.local and 100 loader.rc.local instead. 101 10220151026: 103 NTP has been upgraded to 4.2.8p4. 104 10520151025: 106 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 107 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 108 and devel/kyua to version 0.20+ and adjust any calling code to work 109 with Kyuafile and kyua. 110 11120150823: 112 The polarity of Pulse Per Second (PPS) capture events with the 113 uart(4) driver has been corrected. Prior to this change the PPS 114 "assert" event corresponded to the trailing edge of a positive PPS 115 pulse and the "clear" event was the leading edge of the next pulse. 116 117 As the width of a PPS pulse in a typical GPS receiver is on the 118 order of 1 millisecond, most users will not notice any significant 119 difference with this change. 120 121 Anyone who has compensated for the historical polarity reversal by 122 configuring a negative offset equal to the pulse width will need to 123 remove that workaround. 124 12520150822: 126 From legacy ata(4) driver was removed support for SATA controllers 127 supported by more functional drivers ahci(4), siis(4) and mvs(4). 128 Kernel modules ataahci and ataadaptec were removed completely, 129 replaced by ahci and mvs modules respectively. 130 13120150813: 132 10.2-RELEASE. 133 13420150731: 135 As ZFS requires more kernel stack pages than is the default on some 136 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 137 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 138 139 Please consider using 'options KSTACK_PAGES=X' where X is greater 140 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 141 14220150703: 143 The default Unbound configuration now enables remote control 144 using a local socket. Users who have already enabled the 145 local_unbound service should regenerate their configuration 146 by running "service local_unbound setup" as root. 147 14820150624: 149 An additional fix for the issue described in the 20150614 sendmail 150 entry below has been been committed in revision 284786. 151 15220150615: 153 The fix for the issue described in the 20150614 sendmail entry 154 below has been been committed in revision 284485. The work 155 around described in that entry is no longer needed unless the 156 default setting is overridden by a confDH_PARAMETERS configuration 157 setting of '5' or pointing to a 512 bit DH parameter file. 158 15920150614: 160 The import of openssl to address the FreeBSD-SA-15:10.openssl 161 security advisory includes a change which rejects handshakes 162 with DH parameters below 768 bits. sendmail releases prior 163 to 8.15.2 (not yet released), defaulted to a 512 bit 164 DH parameter setting for client connections. To work around 165 this interoperability, sendmail can be configured to use a 166 2048 bit DH parameter by: 167 168 1. Edit /etc/mail/`hostname`.mc 169 2. If a setting for confDH_PARAMETERS does not exist or 170 exists and is set to a string beginning with '5', 171 replace it with '2'. 172 3. If a setting for confDH_PARAMETERS exists and is set to 173 a file path, create a new file with: 174 openssl dhparam -out /path/to/file 2048 175 4. Rebuild the .cf file: 176 cd /etc/mail/; make; make install 177 5. Restart sendmail: 178 cd /etc/mail/; make restart 179 180 A sendmail patch is coming, at which time this file will be 181 updated. 182 18320150601: 184 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 185 defined in symlink(7); previously symlinks were silently ignored. 186 18720150430: 188 The const qualifier has been removed from iconv(3) to comply with 189 POSIX. The ports tree is aware of this from r384038 onwards. 190 19120141215: 192 At svn r275807, The default linux compat kernel ABI has been adjusted 193 to 2.6.18 in support of the linux-c6 compat ports infrastructure 194 update. If you wish to continue using the linux-f10 compat ports, 195 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 196 encouraged to update their linux-compat packages to linux-c6 during 197 their next update cycle. 198 199 See ports/UPDATING 20141209 and 20141215 on migration to CentOS 6 ports. 200 20120141205: 202 pjdfstest has been integrated into kyua as an opt-in test suite. 203 Please see share/doc/pjdfstest/README for a more details on how to 204 execute it. 205 20620141118: 207 10.1-RELEASE. 208 20920140904: 210 The ofwfb driver, used to provide a graphics console on PowerPC when 211 using vt(4), no longer allows mmap() of all of physical memory. This 212 will prevent Xorg on PowerPC with some ATI graphics cards from 213 initializing properly unless x11-servers/xorg-server is updated to 214 1.12.4_8 or newer. 215 21620140831: 217 The libatf-c and libatf-c++ major versions were downgraded to 0 and 218 1 respectively to match the upstream numbers. They were out of 219 sync because, when they were originally added to FreeBSD, the 220 upstream versions were not respected. These libraries are private 221 and not yet built by default, so renumbering them should be a 222 non-issue. However, unclean source trees will yield broken test 223 programs once the operator executes "make delete-old-libs" after a 224 "make installworld". 225 226 Additionally, the atf-sh binary was made private by moving it into 227 /usr/libexec/. Already-built shell test programs will keep the 228 path to the old binary so they will break after "make delete-old" 229 is run. 230 231 If you are using WITH_TESTS=yes (not the default), wipe the object 232 tree and rebuild from scratch to prevent spurious test failures. 233 This is only needed once: the misnumbered libraries and misplaced 234 binaries have been added to OptionalObsoleteFiles.inc so they will 235 be removed during a clean upgrade. 236 23720140814: 238 The ixgbe tunables now match their sysctl counterparts, for example: 239 hw.ixgbe.enable_aim => hw.ix.enable_aim 240 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 241 24220140801: 243 The NFSv4.1 server committed by r269398 changes the internal 244 function call interfaces used between the NFS and krpc modules. 245 As such, __FreeBSD_version was bumped. 246 24720140729: 248 The default unbound configuration has been modified to address 249 issues with reverse lookups on networks that use private 250 address ranges. If you use the local_unbound service, run 251 "service local_unbound setup" as root to regenerate your 252 configuration, then "service local_unbound reload" to load the 253 new configuration. 254 25520140717: 256 It is no longer necessary to include the dwarf version in your DEBUG 257 options in your kernel config file. The bug that required it to be 258 placed in the config file has bene fixed. DEBUG should now just 259 contain -g. The build system will automatically update things 260 to do the right thing. 261 26220140715: 263 Several ABI breaking changes were merged to CTL and new iSCSI code. 264 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 265 iscsictl need to be rebuilt to work with a new kernel. 266 26720140708: 268 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 269 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 270 which differs from the behaviour controlled by this knob.) 271 27220140608: 273 On i386 and amd64 systems, the onifconsole flag is now set by default 274 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 275 as a login TTY if it is set in the bootloader as an active kernel 276 console. No changes in behavior should result otherwise. To revert to 277 the previous behavior, set ttyu0 to "off" in /etc/ttys. 278 27920140512: 280 Clang and llvm have been upgraded to 3.4.1 release. 281 28220140321: 283 Clang and llvm have been upgraded to 3.4 release. 284 28520140306: 286 If a Makefile in a tests/ directory was auto-generating a Kyuafile 287 instead of providing an explicit one, this would prevent such 288 Makefile from providing its own Kyuafile in the future during 289 NO_CLEAN builds. This has been fixed in the Makefiles but manual 290 intervention is needed to clean an objdir if you use NO_CLEAN: 291 # find /usr/obj -name Kyuafile | xargs rm -f 292 29320140303: 294 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 295 capability mode support. Please note that enabling the feature in 296 kernel is still highly recommended. 297 29820140227: 299 OpenSSH is now built with sandbox support, and will use sandbox as 300 the default privilege separation method. This requires Capsicum 301 capability mode support in kernel. 302 30320140216: 304 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 305 been deprecated and will not be part of FreeBSD 11.0 and later 306 releases. If you use this driver, please consider switching to 307 the nfe(4) driver instead. 308 30920140120: 310 10.0-RELEASE. 311 31220131216: 313 The behavior of gss_pseudo_random() for the krb5 mechanism 314 has changed, for applications requesting a longer random string 315 than produced by the underlying enctype's pseudo-random() function. 316 In particular, the random string produced from a session key of 317 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 318 be different at the 17th octet and later, after this change. 319 The counter used in the PRF+ construction is now encoded as a 320 big-endian integer in accordance with RFC 4402. 321 __FreeBSD_version is bumped to 1000701. 322 32320131108: 324 The WITHOUT_ATF build knob has been removed and its functionality 325 has been subsumed into the more generic WITHOUT_TESTS. If you were 326 using the former to disable the build of the ATF libraries, you 327 should change your settings to use the latter. 328 32920131031: 330 The default version of mtree is nmtree which is obtained from 331 NetBSD. The output is generally the same, but may vary 332 slightly. If you found you need identical output adding 333 "-F freebsd9" to the command line should do the trick. For the 334 time being, the old mtree is available as fmtree. 335 33620131014: 337 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 338 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 339 1.1.4_8 and verify bsdyml not linked in, before running "make 340 delete-old-libs": 341 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 342 or 343 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 344 34520131010: 346 The rc.d/jail script has been updated to support jail(8) 347 configuration file. The "jail_<jname>_*" rc.conf(5) variables 348 for per-jail configuration are automatically converted to 349 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 350 This is transparently backward compatible. See below about some 351 incompatibilities and rc.conf(5) manual page for more details. 352 353 These variables are now deprecated in favor of jail(8) configuration 354 file. One can use "rc.d/jail config <jname>" command to generate 355 a jail(8) configuration file in /var/run/jail.<jname>.conf without 356 running the jail(8) utility. The default pathname of the 357 configuration file is /etc/jail.conf and can be specified by 358 using $jail_conf or $jail_<jname>_conf variables. 359 360 Please note that jail_devfs_ruleset accepts an integer at 361 this moment. Please consider to rewrite the ruleset name 362 with an integer. 363 36420130930: 365 BIND has been removed from the base system. If all you need 366 is a local resolver, simply enable and start the local_unbound 367 service instead. Otherwise, several versions of BIND are 368 available in the ports tree. The dns/bind99 port is one example. 369 370 With this change, nslookup(1) and dig(1) are no longer in the base 371 system. Users should instead use host(1) and drill(1) which are 372 in the base system. Alternatively, nslookup and dig can 373 be obtained by installing the dns/bind-tools port. 374 37520130916: 376 With the addition of unbound(8), a new unbound user is now 377 required during installworld. "mergemaster -p" can be used to 378 add the user prior to installworld, as documented in the handbook. 379 38020130911: 381 OpenSSH is now built with DNSSEC support, and will by default 382 silently trust signed SSHFP records. This can be controlled with 383 the VerifyHostKeyDNS client configuration setting. DNSSEC support 384 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 385 38620130906: 387 The GNU Compiler Collection and C++ standard library (libstdc++) 388 are no longer built by default on platforms where clang is the system 389 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 390 options in src.conf. 391 39220130905: 393 The PROCDESC kernel option is now part of the GENERIC kernel 394 configuration and is required for the rwhod(8) to work. 395 If you are using custom kernel configuration, you should include 396 'options PROCDESC'. 397 39820130905: 399 The API and ABI related to the Capsicum framework was modified 400 in backward incompatible way. The userland libraries and programs 401 have to be recompiled to work with the new kernel. This includes the 402 following libraries and programs, but the whole buildworld is 403 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 404 kdump, procstat, rwho, rwhod, uniq. 405 40620130903: 407 AES-NI intrinsic support has been added to gcc. The AES-NI module 408 has been updated to use this support. A new gcc is required to build 409 the aesni module on both i386 and amd64. 410 41120130821: 412 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 413 Thus "device padlock_rng" and "device rdrand_rng" should be 414 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 415 41620130813: 417 WITH_ICONV has been split into two feature sets. WITH_ICONV now 418 enables just the iconv* functionality and is now on by default. 419 WITH_LIBICONV_COMPAT enables the libiconv api and link time 420 compatability. Set WITHOUT_ICONV to build the old way. 421 If you have been using WITH_ICONV before, you will very likely 422 need to turn on WITH_LIBICONV_COMPAT. 423 42420130806: 425 INVARIANTS option now enables DEBUG for code with OpenSolaris and 426 Illumos origin, including ZFS. If you have INVARIANTS in your 427 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 428 explicitly. 429 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 430 locks if WITNESS option was set. Because that generated a lot of 431 witness(9) reports and all of them were believed to be false 432 positives, this is no longer done. New option OPENSOLARIS_WITNESS 433 can be used to achieve the previous behavior. 434 43520130806: 436 Timer values in IPv6 data structures now use time_uptime instead 437 of time_second. Although this is not a user-visible functional 438 change, userland utilities which directly use them---ndp(8), 439 rtadvd(8), and rtsold(8) in the base system---need to be updated 440 to r253970 or later. 441 44220130802: 443 find -delete can now delete the pathnames given as arguments, 444 instead of only files found below them or if the pathname did 445 not contain any slashes. Formerly, the following error message 446 would result: 447 448 find: -delete: <path>: relative path potentially not safe 449 450 Deleting the pathnames given as arguments can be prevented 451 without error messages using -mindepth 1 or by changing 452 directory and passing "." as argument to find. This works in the 453 old as well as the new version of find. 454 45520130726: 456 Behavior of devfs rules path matching has been changed. 457 Pattern is now always matched against fully qualified devfs 458 path and slash characters must be explicitly matched by 459 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 460 subdirectories must be reviewed. 461 46220130716: 463 The default ARM ABI has changed to the ARM EABI. The old ABI is 464 incompatible with the ARM EABI and all programs and modules will 465 need to be rebuilt to work with a new kernel. 466 467 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 468 469 NOTE: Support for the old ABI will be removed in the future and 470 users are advised to upgrade. 471 47220130709: 473 pkg_install has been disconnected from the build if you really need it 474 you should add WITH_PKGTOOLS in your src.conf(5). 475 47620130709: 477 Most of network statistics structures were changed to be able 478 keep 64-bits counters. Thus all tools, that work with networking 479 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 480 48120130618: 482 Fix a bug that allowed a tracing process (e.g. gdb) to write 483 to a memory-mapped file in the traced process's address space 484 even if neither the traced process nor the tracing process had 485 write access to that file. 486 48720130615: 488 CVS has been removed from the base system. An exact copy 489 of the code is available from the devel/cvs port. 490 49120130613: 492 Some people report the following error after the switch to bmake: 493 494 make: illegal option -- J 495 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 496 ... 497 *** [buildworld] Error code 2 498 499 this likely due to an old instance of make in 500 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 501 which src/Makefile will use that blindly, if it exists, so if 502 you see the above error: 503 504 rm -rf `make -V MAKEPATH` 505 506 should resolve it. 507 50820130516: 509 Use bmake by default. 510 Whereas before one could choose to build with bmake via 511 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 512 make. The goal is to remove these knobs for 10-RELEASE. 513 514 It is worth noting that bmake (like gmake) treats the command 515 line as the unit of failure, rather than statements within the 516 command line. Thus '(cd some/where && dosomething)' is safer 517 than 'cd some/where; dosomething'. The '()' allows consistent 518 behavior in parallel build. 519 52020130429: 521 Fix a bug that allows NFS clients to issue READDIR on files. 522 52320130426: 524 The WITHOUT_IDEA option has been removed because 525 the IDEA patent expired. 526 52720130426: 528 The sysctl which controls TRIM support under ZFS has been renamed 529 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 530 enabled by default. 531 53220130425: 533 The mergemaster command now uses the default MAKEOBJDIRPREFIX 534 rather than creating it's own in the temporary directory in 535 order allow access to bootstrapped versions of tools such as 536 install and mtree. When upgrading from version of FreeBSD where 537 the install command does not support -l, you will need to 538 install a new mergemaster command if mergemaster -p is required. 539 This can be accomplished with the command (cd src/usr.sbin/mergemaster 540 && make install). 541 54220130404: 543 Legacy ATA stack, disabled and replaced by new CAM-based one since 544 FreeBSD 9.0, completely removed from the sources. Kernel modules 545 atadisk and atapi*, user-level tools atacontrol and burncd are 546 removed. Kernel option `options ATA_CAM` is now permanently enabled 547 and removed. 548 54920130319: 550 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 551 and socketpair(2). Software, in particular Kerberos, may 552 automatically detect and use these during building. The resulting 553 binaries will not work on older kernels. 554 55520130308: 556 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 557 information, see the respective 20130304 entry). 558 55920130304: 560 Recent commits to callout(9) changed the size of struct callout, 561 so the KBI is probably heavily disturbed. Also, some functions 562 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 563 by macros. Every kernel module using it won't load, so rebuild 564 is requested. 565 566 The ctl device has been re-enabled in GENERIC for i386 and amd64, 567 but does not initialize by default (because of the new CTL_DISABLE 568 option) to save memory. To re-enable it, remove the CTL_DISABLE 569 option from the kernel config file or set kern.cam.ctl.disable=0 570 in /boot/loader.conf. 571 57220130301: 573 The ctl device has been disabled in GENERIC for i386 and amd64. 574 This was done due to the extra memory being allocated at system 575 initialisation time by the ctl driver which was only used if 576 a CAM target device was created. This makes a FreeBSD system 577 unusable on 128MB or less of RAM. 578 57920130208: 580 A new compression method (lz4) has been merged to -HEAD. Please 581 refer to zpool-features(7) for more information. 582 583 Please refer to the "ZFS notes" section of this file for information 584 on upgrading boot ZFS pools. 585 58620130129: 587 A BSD-licensed patch(1) variant has been added and is installed 588 as bsdpatch, being the GNU version the default patch. 589 To inverse the logic and use the BSD-licensed one as default, 590 while having the GNU version installed as gnupatch, rebuild 591 and install world with the WITH_BSD_PATCH knob set. 592 59320130121: 594 Due to the use of the new -l option to install(1) during build 595 and install, you must take care not to directly set the INSTALL 596 make variable in your /etc/make.conf, /etc/src.conf, or on the 597 command line. If you wish to use the -C flag for all installs 598 you may be able to add INSTALL+=-C to /etc/make.conf or 599 /etc/src.conf. 600 60120130118: 602 The install(1) option -M has changed meaning and now takes an 603 argument that is a file or path to append logs to. In the 604 unlikely event that -M was the last option on the command line 605 and the command line contained at least two files and a target 606 directory the first file will have logs appended to it. The -M 607 option served little practical purpose in the last decade so its 608 use is expected to be extremely rare. 609 61020121223: 611 After switching to Clang as the default compiler some users of ZFS 612 on i386 systems started to experience stack overflow kernel panics. 613 Please consider using 'options KSTACK_PAGES=4' in such configurations. 614 61520121222: 616 GEOM_LABEL now mangles label names read from file system metadata. 617 Mangling affect labels containing spaces, non-printable characters, 618 '%' or '"'. Device names in /etc/fstab and other places may need to 619 be updated. 620 62120121217: 622 By default, only the 10 most recent kernel dumps will be saved. To 623 restore the previous behaviour (no limit on the number of kernel dumps 624 stored in the dump directory) add the following line to /etc/rc.conf: 625 626 savecore_flags="" 627 62820121201: 629 With the addition of auditdistd(8), a new auditdistd user is now 630 required during installworld. "mergemaster -p" can be used to 631 add the user prior to installworld, as documented in the handbook. 632 63320121117: 634 The sin6_scope_id member variable in struct sockaddr_in6 is now 635 filled by the kernel before passing the structure to the userland via 636 sysctl or routing socket. This means the KAME-specific embedded scope 637 id in sin6_addr.s6_addr[2] is always cleared in userland application. 638 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 639 __FreeBSD_version is bumped to 1000025. 640 64120121105: 642 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 643 This means that the world and kernel will be compiled with clang 644 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 645 and /usr/bin/cpp. To disable this behavior and revert to building 646 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 647 of current may need to bootstrap WITHOUT_CLANG first if the clang 648 build fails (its compatibility window doesn't extend to the 9 stable 649 branch point). 650 65120121102: 652 The IPFIREWALL_FORWARD kernel option has been removed. Its 653 functionality now turned on by default. 654 65520121023: 656 The ZERO_COPY_SOCKET kernel option has been removed and 657 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 658 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 659 mechanism which is not safe and may result in kernel crashes. 660 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 661 driver supports disposeable external page sized mbuf storage. 662 Proper replacements for both zero-copy mechanisms are under 663 consideration and will eventually lead to complete removal 664 of the two kernel options. 665 66620121023: 667 The IPv4 network stack has been converted to network byte 668 order. The following modules need to be recompiled together 669 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 670 pf(4), ipfw(4), ng_ipfw(4), stf(4). 671 67220121022: 673 Support for non-MPSAFE filesystems was removed from VFS. The 674 VFS_VERSION was bumped, all filesystem modules shall be 675 recompiled. 676 67720121018: 678 All the non-MPSAFE filesystems have been disconnected from 679 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 680 portalfs, smbfs, xfs. 681 68220121016: 683 The interface cloning API and ABI has changed. The following 684 modules need to be recompiled together with kernel: 685 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 686 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 687 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 688 68920121015: 690 The sdhci driver was split in two parts: sdhci (generic SD Host 691 Controller logic) and sdhci_pci (actual hardware driver). 692 No kernel config modifications are required, but if you 693 load sdhc as a module you must switch to sdhci_pci instead. 694 69520121014: 696 Import the FUSE kernel and userland support into base system. 697 69820121013: 699 The GNU sort(1) program has been removed since the BSD-licensed 700 sort(1) has been the default for quite some time and no serious 701 problems have been reported. The corresponding WITH_GNU_SORT 702 knob has also gone. 703 70420121006: 705 The pfil(9) API/ABI for AF_INET family has been changed. Packet 706 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 707 with new kernel. 708 70920121001: 710 The net80211(4) ABI has been changed to allow for improved driver 711 PS-POLL and power-save support. All wireless drivers need to be 712 recompiled to work with the new kernel. 713 71420120913: 715 The random(4) support for the VIA hardware random number 716 generator (`PADLOCK') is no longer enabled unconditionally. 717 Add the padlock_rng device in the custom kernel config if 718 needed. The GENERIC kernels on i386 and amd64 do include the 719 device, so the change only affects the custom kernel 720 configurations. 721 72220120908: 723 The pf(4) packet filter ABI has been changed. pfctl(8) and 724 snmp_pf module need to be recompiled to work with new kernel. 725 72620120828: 727 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 728 to -HEAD. Pools that have empty_bpobj in active state can not be 729 imported read-write with ZFS implementations that do not support 730 this feature. For more information read the zpool-features(5) 731 manual page. 732 73320120727: 734 The sparc64 ZFS loader has been changed to no longer try to auto- 735 detect ZFS providers based on diskN aliases but now requires these 736 to be explicitly listed in the OFW boot-device environment variable. 737 73820120712: 739 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 740 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 741 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 742 74320120712: 744 The following sysctls and tunables have been renamed for consistency 745 with other variables: 746 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 747 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 748 74920120628: 750 The sort utility has been replaced with BSD sort. For now, GNU sort 751 is also available as "gnusort" or the default can be set back to 752 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 753 installed as "bsdsort". 754 75520120611: 756 A new version of ZFS (pool version 5000) has been merged to -HEAD. 757 Starting with this version the old system of ZFS pool versioning 758 is superseded by "feature flags". This concept enables forward 759 compatibility against certain future changes in functionality of ZFS 760 pools. The first read-only compatible "feature flag" for ZFS pools 761 is named "com.delphix:async_destroy". For more information 762 read the new zpool-features(5) manual page. 763 Please refer to the "ZFS notes" section of this file for information 764 on upgrading boot ZFS pools. 765 76620120417: 767 The malloc(3) implementation embedded in libc now uses sources imported 768 as contrib/jemalloc. The most disruptive API change is to 769 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 770 delete it prior to installworld, and optionally re-create it using the 771 new format after rebooting. See malloc.conf(5) for details 772 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 773 NAMESPACE section). 774 77520120328: 776 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 777 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 778 now spelled mips. This is to aid compatibility with third-party 779 software that expects this naming scheme in uname(3). Little-endian 780 settings are unchanged. If you are updating a big-endian mips64 machine 781 from before this change, you may need to set MACHINE_ARCH=mips64 in 782 your environment before the new build system will recognize your machine. 783 78420120306: 785 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 786 platforms. 787 78820120229: 789 Now unix domain sockets behave "as expected" on nullfs(5). Previously 790 nullfs(5) did not pass through all behaviours to the underlying layer, 791 as a result if we bound to a socket on the lower layer we could connect 792 only to the lower path; if we bound to the upper layer we could connect 793 only to the upper path. The new behavior is one can connect to both the 794 lower and the upper paths regardless what layer path one binds to. 795 79620120211: 797 The getifaddrs upgrade path broken with 20111215 has been restored. 798 If you have upgraded in between 20111215 and 20120209 you need to 799 recompile libc again with your kernel. You still need to recompile 800 world to be able to configure CARP but this restriction already 801 comes from 20111215. 802 80320120114: 804 The set_rcvar() function has been removed from /etc/rc.subr. All 805 base and ports rc.d scripts have been updated, so if you have a 806 port installed with a script in /usr/local/etc/rc.d you can either 807 hand-edit the rcvar= line, or reinstall the port. 808 809 An easy way to handle the mass-update of /etc/rc.d: 810 rm /etc/rc.d/* && mergemaster -i 811 81220120109: 813 panic(9) now stops other CPUs in the SMP systems, disables interrupts 814 on the current CPU and prevents other threads from running. 815 This behavior can be reverted using the kern.stop_scheduler_on_panic 816 tunable/sysctl. 817 The new behavior can be incompatible with kern.sync_on_panic. 818 81920111215: 820 The carp(4) facility has been changed significantly. Configuration 821 of the CARP protocol via ifconfig(8) has changed, as well as format 822 of CARP events submitted to devd(8) has changed. See manual pages 823 for more information. The arpbalance feature of carp(4) is currently 824 not supported anymore. 825 826 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 827 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 828 need to be recompiled. 829 83020111122: 831 The acpi_wmi(4) status device /dev/wmistat has been renamed to 832 /dev/wmistat0. 833 83420111108: 835 The option VFS_ALLOW_NONMPSAFE option has been added in order to 836 explicitely support non-MPSAFE filesystems. 837 It is on by default for all supported platform at this present 838 time. 839 84020111101: 841 The broken amd(4) driver has been replaced with esp(4) in the amd64, 842 i386 and pc98 GENERIC kernel configuration files. 843 84420110930: 845 sysinstall has been removed 846 84720110923: 848 The stable/9 branch created in subversion. This corresponds to the 849 RELENG_9 branch in CVS. 850 85120110913: 852 This commit modifies vfs_register() so that it uses a hash 853 calculation to set vfc_typenum, which is enabled by default. 854 The first time a system is booted after this change, the 855 vfc_typenum values will change for all file systems. The 856 main effect of this is a change to the NFS server file handles 857 for file systems that use vfc_typenum in their fsid, such as ZFS. 858 It will, however, prevent vfc_typenum from changing when file 859 systems are loaded in a different order for subsequent reboots. 860 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 861 until you are ready to remount all NFS clients after a reboot. 862 86320110828: 864 Bump the shared library version numbers for libraries that 865 do not use symbol versioning, have changed the ABI compared 866 to stable/8 and which shared library version was not bumped. 867 Done as part of 9.0-RELEASE cycle. 868 86920110815: 870 During the merge of Capsicum features, the fget(9) KPI was modified. 871 This may require the rebuilding of out-of-tree device drivers -- 872 issues have been reported specifically with the nVidia device driver. 873 __FreeBSD_version is bumped to 900041. 874 875 Also, there is a period between 20110811 and 20110814 where the 876 special devices /dev/{stdin,stdout,stderr} did not work correctly. 877 Building world from a kernel during that window may not work. 878 87920110628: 880 The packet filter (pf) code has been updated to OpenBSD 4.5. 881 You need to update userland tools to be in sync with kernel. 882 This update breaks backward compatibility with earlier pfsync(4) 883 versions. Care must be taken when updating redundant firewall setups. 884 88520110608: 886 The following sysctls and tunables are retired on x86 platforms: 887 machdep.hlt_cpus 888 machdep.hlt_logical_cpus 889 The following sysctl is retired: 890 machdep.hyperthreading_allowed 891 The sysctls were supposed to provide a way to dynamically offline and 892 online selected CPUs on x86 platforms, but the implementation has not 893 been reliable especially with SCHED_ULE scheduler. 894 machdep.hyperthreading_allowed tunable is still available to ignore 895 hyperthreading CPUs at OS level. 896 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 897 where X is an APIC ID of a CPU. Be advised, though, that disabling 898 CPUs in non-uniform fashion will result in non-uniform topology and 899 may lead to sub-optimal system performance with SCHED_ULE, which is 900 a default scheduler. 901 90220110607: 903 cpumask_t type is retired and cpuset_t is used in order to describe 904 a mask of CPUs. 905 90620110531: 907 Changes to ifconfig(8) for dynamic address family detection mandate 908 that you are running a kernel of 20110525 or later. Make sure to 909 follow the update procedure to boot a new kernel before installing 910 world. 911 91220110513: 913 Support for sun4v architecture is officially dropped 914 91520110503: 916 Several KPI breaking changes have been committed to the mii(4) layer, 917 the PHY drivers and consequently some Ethernet drivers using mii(4). 918 This means that miibus.ko and the modules of the affected Ethernet 919 drivers need to be recompiled. 920 921 Note to kernel developers: Given that the OUI bit reversion problem 922 was fixed as part of these changes all mii(4) commits related to OUIs, 923 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 924 handling, no longer can be merged verbatim to stable/8 and previous 925 branches. 926 92720110430: 928 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 929 into their kernel configurations along with 'device pci'. 930 93120110427: 932 The default NFS client is now the new NFS client, so fstype "newnfs" 933 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 934 Although mounts via fstype "nfs" will usually work without userland 935 changes, it is recommended that the mount(8) and mount_nfs(8) 936 commands be rebuilt from sources and that a link to mount_nfs called 937 mount_oldnfs be created. The new client is compiled into the 938 kernel with "options NFSCL" and this is needed for diskless root 939 file systems. The GENERIC kernel configs have been changed to use 940 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 941 To use the regular/old client, you can "mount -t oldnfs ...". For 942 a diskless root file system, you must also include a line like: 943 944 vfs.root.mountfrom="oldnfs:" 945 946 in the boot/loader.conf on the root fs on the NFS server to make 947 a diskless root fs use the old client. 948 94920110424: 950 The GENERIC kernels for all architectures now default to the new 951 CAM-based ATA stack. It means that all legacy ATA drivers were 952 removed and replaced by respective CAM drivers. If you are using 953 ATA device names in /etc/fstab or other places, make sure to update 954 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 955 where 'Y's are the sequential numbers starting from zero for each type 956 in order of detection, unless configured otherwise with tunables, 957 see cam(4)). There will be symbolic links created in /dev/ to map 958 old adX devices to the respective adaY. They should provide basic 959 compatibility for file systems mounting in most cases, but they do 960 not support old user-level APIs and do not have respective providers 961 in GEOM. Consider using updated management tools with new device names. 962 963 It is possible to load devices ahci, ata, siis and mvs as modules, 964 but option ATA_CAM should remain in kernel configuration to make ata 965 module work as CAM driver supporting legacy ATA controllers. Device ata 966 still can be used in modular fashion (atacore + ...). Modules atadisk 967 and atapi* are not used and won't affect operation in ATA_CAM mode. 968 Note that to use CAM-based ATA kernel should include CAM devices 969 scbus, pass, da (or explicitly ada), cd and optionally others. All of 970 them are parts of the cam module. 971 972 ataraid(4) functionality is now supported by the RAID GEOM class. 973 To use it you can load geom_raid kernel module and use graid(8) tool 974 for management. Instead of /dev/arX device names, use /dev/raid/rX. 975 976 No kernel config options or code have been removed, so if a problem 977 arises, please report it and optionally revert to the old ATA stack. 978 In order to do it you can remove from the kernel config: 979 options ATA_CAM 980 device ahci 981 device mvs 982 device siis 983 , and instead add back: 984 device atadisk # ATA disk drives 985 device ataraid # ATA RAID drives 986 device atapicd # ATAPI CDROM drives 987 device atapifd # ATAPI floppy drives 988 device atapist # ATAPI tape drives 989 99020110423: 991 The default NFS server has been changed to the new server, which 992 was referred to as the experimental server. If you need to switch 993 back to the old NFS server, you must now put the "-o" option on 994 both the mountd and nfsd commands. This can be done using the 995 mountd_flags and nfs_server_flags rc.conf variables until an 996 update to the rc scripts is committed, which is coming soon. 997 99820110418: 999 The GNU Objective-C runtime library (libobjc), and other Objective-C 1000 related components have been removed from the base system. If you 1001 require an Objective-C library, please use one of the available ports. 1002 100320110331: 1004 ath(4) has been split into bus- and device- modules. if_ath contains 1005 the HAL, the TX rate control and the network device code. if_ath_pci 1006 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1007 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1008 in order to use ath on everything else. 1009 1010 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1011 need to load if_ath and if_ath_pci for ath(4) operation. 1012 101320110314: 1014 As part of the replacement of sysinstall, the process of building 1015 release media has changed significantly. For details, please re-read 1016 release(7), which has been updated to reflect the new build process. 1017 101820110218: 1019 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1020 is the last available version under GPLv2. It brings a number of new 1021 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1022 4.1 and SSE 4.2), better support for powerpc64, a number of new 1023 directives, and lots of other small improvements. See the ChangeLog 1024 file in contrib/binutils for the full details. 1025 102620110218: 1027 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1028 compliant, and will now use half of hash for authentication. 1029 This will break interoperability with all stacks (including all 1030 actual FreeBSD versions) who implement 1031 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1032 authentication). 1033 The only workaround with such peers is to use another HMAC 1034 algorithm for IPsec ("phase 2") authentication. 1035 103620110207: 1037 Remove the uio_yield prototype and symbol. This function has 1038 been misnamed since it was introduced and should not be 1039 globally exposed with this name. The equivalent functionality 1040 is now available using kern_yield(curthread->td_user_pri). 1041 The function remains undocumented. 1042 104320110112: 1044 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1045 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1046 for scalar sysctls is defined but disabled. Code that needs 1047 UQUAD to pass the type checking that must compile on older 1048 systems where the define is not present can check against 1049 __FreeBSD_version >= 900030. 1050 1051 The system dialog(1) has been replaced with a new version previously 1052 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1053 with the previous version, but the libdialog associated with it has 1054 a largely incompatible API. As such, the original version of libdialog 1055 will be kept temporarily as libodialog, until its base system consumers 1056 are replaced or updated. Bump __FreeBSD_version to 900030. 1057 105820110103: 1059 If you are trying to run make universe on a -stable system, and you get 1060 the following warning: 1061 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1062 unknown. config(8) likely too old." 1063 or something similar to it, then you must upgrade your -stable system 1064 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1065 stable/8) or build the config from the latest stable/8 branch and 1066 install it on your system. 1067 1068 Prior to this date, building a current universe on 8-stable system from 1069 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1070 error in the first kernel build phase. A new config on those old 1071 systems will fix that problem for older versions of -current. 1072 107320101228: 1074 The TCP stack has been modified to allow Khelp modules to interact with 1075 it via helper hook points and store per-connection data in the TCP 1076 control block. Bump __FreeBSD_version to 900029. User space tools that 1077 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1078 be recompiled. 1079 108020101114: 1081 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1082 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1083 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1084 to take advantage of it instead of using custom implementations. This 1085 means that these drivers now no longer unconditionally advertise 1086 support for flow control but only do so if flow control is a selected 1087 media option. This was implemented in the generic support that way in 1088 order to allow flow control to be switched on and off via ifconfig(8) 1089 with the PHY specific default to typically off in order to protect 1090 from unwanted effects. Consequently, if you used flow control with 1091 one of the above mentioned drivers you now need to explicitly enable 1092 it, for example via: 1093 ifconfig bge0 media auto mediaopt flowcontrol 1094 1095 Along with the above mentioned changes generic support for setting 1096 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1097 e1000phy(4) as well as ip1000phy(4) have been converted to take 1098 advantage of it. This means that these drivers now no longer take the 1099 link0 parameter for selecting master mode but the master media option 1100 has to be used instead, for example like in the following: 1101 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1102 1103 Selection of master mode now is also available with all other PHY 1104 drivers supporting 1000baseT. 1105 110620101111: 1107 The TCP stack has received a significant update to add support for 1108 modularised congestion control and generally improve the clarity of 1109 congestion control decisions. Bump __FreeBSD_version to 900025. User 1110 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1111 sockstat) need to be recompiled. 1112 111320101002: 1114 The man(1) utility has been replaced by a new version that no longer 1115 uses /etc/manpath.config. Please consult man.conf(5) for how to 1116 migrate local entries to the new format. 1117 111820100928: 1119 The copyright strings printed by login(1) and sshd(8) at the time of a 1120 new connection have been removed to follow other operating systems and 1121 upstream sshd. 1122 112320100915: 1124 A workaround for a fixed ld bug has been removed in kernel code, 1125 so make sure that your system ld is built from sources after 1126 revision 210245 from 2010-07-19 (r211583 if building head kernel 1127 on stable/8, r211584 for stable/7; both from 2010-08-21). 1128 A symptom of incorrect ld version is different addresses for 1129 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1130 113120100913: 1132 The $ipv6_prefer variable in rc.conf(5) has been split into 1133 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1134 1135 The $ip6addrctl_policy is a variable to choose a pre-defined 1136 address selection policy set by ip6addrctl(8). A value 1137 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1138 default is "AUTO". 1139 1140 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1141 flag (see an entry of 20090926) is set on an interface with no 1142 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1143 security reason. If you want IPv6 link-local address on all 1144 interfaces by default, set this to "YES". 1145 1146 The old ipv6_prefer="YES" is equivalent to 1147 ipv6_activate_all_interfaces="YES" and 1148 ip6addrctl_policy="ipv6_prefer". 1149 115020100913: 1151 DTrace has grown support for userland tracing. Due to this, DTrace is 1152 now i386 and amd64 only. 1153 dtruss(1) is now installed by default on those systems and a new 1154 kernel module is needed for userland tracing: fasttrap. 1155 No changes to your kernel config file are necessary to enable 1156 userland tracing, but you might consider adding 'STRIP=' and 1157 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1158 to have informative userland stack traces in DTrace (ustack). 1159 116020100725: 1161 The acpi_aiboost(4) driver has been removed in favor of the new 1162 aibs(4) driver. You should update your kernel configuration file. 1163 116420100722: 1165 BSD grep has been imported to the base system and it is built by 1166 default. It is completely BSD licensed, highly GNU-compatible, uses 1167 less memory than its GNU counterpart and has a small codebase. 1168 However, it is slower than its GNU counterpart, which is mostly 1169 noticeable for larger searches, for smaller ones it is measurable 1170 but not significant. The reason is complex, the most important factor 1171 is that we lack a modern and efficient regex library and GNU 1172 overcomes this by optimizing the searches internally. Future work 1173 on improving the regex performance is planned, for the meantime, 1174 users that need better performance, can build GNU grep instead by 1175 setting the WITH_GNU_GREP knob. 1176 117720100713: 1178 Due to the import of powerpc64 support, all existing powerpc kernel 1179 configuration files must be updated with a machine directive like this: 1180 machine powerpc powerpc 1181 1182 In addition, an updated config(8) is required to build powerpc kernels 1183 after this change. 1184 118520100713: 1186 A new version of ZFS (version 15) has been merged to -HEAD. 1187 This version uses a python library for the following subcommands: 1188 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1189 For full functionality of these commands the following port must 1190 be installed: sysutils/py-zfs 1191 119220100429: 1193 'vm_page's are now hashed by physical address to an array of mutexes. 1194 Currently this is only used to serialize access to hold_count. Over 1195 time the page queue mutex will be peeled away. This changes the size 1196 of pmap on every architecture. And requires all callers of vm_page_hold 1197 and vm_page_unhold to be updated. 1198 119920100402: 1200 WITH_CTF can now be specified in src.conf (not recommended, there 1201 are some problems with static executables), make.conf (would also 1202 affect ports which do not use GNU make and do not override the 1203 compile targets) or in the kernel config (via "makeoptions 1204 WITH_CTF=yes"). 1205 When WITH_CTF was specified there before this was silently ignored, 1206 so make sure that WITH_CTF is not used in places which could lead 1207 to unwanted behavior. 1208 120920100311: 1210 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1211 to allow 32-bit compatibility on non-x86 platforms. All kernel 1212 configurations on amd64 and ia64 platforms using these options must 1213 be modified accordingly. 1214 121520100113: 1216 The utmp user accounting database has been replaced with utmpx, 1217 the user accounting interface standardized by POSIX. 1218 Unfortunately the semantics of utmp and utmpx don't match, 1219 making it practically impossible to support both interfaces. 1220 The user accounting database is used by tools like finger(1), 1221 last(1), talk(1), w(1) and ac(8). 1222 1223 All applications in the base system use utmpx. This means only 1224 local binaries (e.g. from the ports tree) may still use these 1225 utmp database files. These applications must be rebuilt to make 1226 use of utmpx. 1227 1228 After the system has been upgraded, it is safe to remove the old 1229 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1230 assuming their contents is of no importance anymore. Old wtmp 1231 databases can only be used by last(1) and ac(8) after they have 1232 been converted to the new format using wtmpcvt(1). 1233 123420100108: 1235 Introduce the kernel thread "deadlock resolver" (which can be enabled 1236 via the DEADLKRES option, see NOTES for more details) and the 1237 sleepq_type() function for sleepqueues. 1238 123920091202: 1240 The rc.firewall and rc.firewall6 were unified, and 1241 rc.firewall6 and rc.d/ip6fw were removed. 1242 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1243 variables are obsoleted. Instead, the following new rc 1244 variables are added to rc.d/ipfw: 1245 1246 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1247 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1248 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1249 1250 The meanings correspond to the relevant IPv4 variables. 1251 125220091125: 1253 8.0-RELEASE. 1254 125520091113: 1256 The default terminal emulation for syscons(4) has been changed 1257 from cons25 to xterm on all platforms except pc98. This means 1258 that the /etc/ttys file needs to be updated to ensure correct 1259 operation of applications on the console. 1260 1261 The terminal emulation style can be toggled per window by using 1262 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1263 options can be used to change the compile-time default back to 1264 cons25. 1265 1266 To prevent graphical artifacts, make sure the TERM environment 1267 variable is set to match the terminal emulation that is being 1268 performed by syscons(4). 1269 127020091109: 1271 The layout of the structure ieee80211req_scan_result has changed. 1272 Applications that require wireless scan results (e.g. ifconfig(8)) 1273 from net80211 need to be recompiled. 1274 1275 Applications such as wpa_supplicant(8) may require a full world 1276 build without using NO_CLEAN in order to get synchronized with the 1277 new structure. 1278 127920091025: 1280 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1281 There's one kernel module for each firmware. Adding "device iwnfw" 1282 to the kernel configuration file means including all three firmware 1283 images inside the kernel. If you want to include just the one for 1284 your wireless card, use the devices iwn4965fw, iwn5000fw or 1285 iwn5150fw. 1286 128720090926: 1288 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1289 into rc.d/netif. The changes are the following: 1290 1291 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1292 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1293 Note that both variables need the "inet6" keyword at the head. 1294 1295 Do not set $ipv6_network_interfaces manually if you do not 1296 understand what you are doing. It is not needed in most cases. 1297 1298 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1299 they are obsolete. 1300 1301 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1302 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1303 1304 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1305 all configured interfaces have "inet6 accept_rtadv" in the 1306 $ifconfig_IF_ipv6. These are for backward compatibility. 1307 1308 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1309 functionality of interfaces with no corresponding 1310 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1311 and the default address selection policy of ip6addrctl(8) 1312 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1313 Note that if you want to configure IPv6 functionality on the 1314 disabled interfaces after boot, first you need to clear the flag by 1315 using ifconfig(8) like: 1316 1317 ifconfig em0 inet6 -ifdisabled 1318 1319 If YES, the default address selection policy is set as 1320 IPv6-preferred. 1321 1322 The default value of $ipv6_prefer is NO. 1323 1324 4. If your system need to receive Router Advertisement messages, 1325 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1326 scripts automatically invoke rtsol(8) when the interface becomes 1327 UP. The Router Advertisement messages are used for SLAAC 1328 (State-Less Address AutoConfiguration). 1329 133020090922: 1331 802.11s D3.03 support was committed. This is incompatible with the 1332 previous code, which was based on D3.0. 1333 133420090912: 1335 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1336 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1337 control whether accepting Router Advertisement messages or not. 1338 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1339 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1340 The ifconfig(8) utility now supports these flags. 1341 134220090910: 1343 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1344 mount(8) and -a option for df(1) to see them. 1345 134620090825: 1347 The old tunable hw.bus.devctl_disable has been superseded by 1348 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1349 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1350 is 1000. 1351 135220090813: 1353 Remove the option STOP_NMI. The default action is now to use NMI only 1354 for KDB via the newly introduced function stop_cpus_hard() and 1355 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1356 135720090803: 1358 The stable/8 branch created in subversion. This corresponds to the 1359 RELENG_8 branch in CVS. 1360 136120090719: 1362 Bump the shared library version numbers for all libraries that do not 1363 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1364 __FreeBSD_version to 800105. 1365 136620090714: 1367 Due to changes in the implementation of virtual network stack support, 1368 all network-related kernel modules must be recompiled. As this change 1369 breaks the ABI, bump __FreeBSD_version to 800104. 1370 137120090713: 1372 The TOE interface to the TCP syncache has been modified to remove 1373 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1374 The cxgb driver is the only TOE consumer affected by this change, and 1375 needs to be recompiled along with the kernel. As this change breaks 1376 the ABI, bump __FreeBSD_version to 800103. 1377 137820090712: 1379 Padding has been added to struct tcpcb, sackhint and tcpstat in 1380 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1381 maintaining the ABI. However, this change breaks the ABI, so bump 1382 __FreeBSD_version to 800102. User space tools that rely on the size of 1383 any of these structs (e.g. sockstat) need to be recompiled. 1384 138520090630: 1386 The NFS_LEGACYRPC option has been removed along with the old kernel 1387 RPC implementation that this option selected. Kernel configurations 1388 may need to be adjusted. 1389 139020090629: 1391 The network interface device nodes at /dev/net/<interface> have been 1392 removed. All ioctl operations can be performed the normal way using 1393 routing sockets. The kqueue functionality can generally be replaced 1394 with routing sockets. 1395 139620090628: 1397 The documentation from the FreeBSD Documentation Project (Handbook, 1398 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1399 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1400 140120090624: 1402 The ABI of various structures related to the SYSV IPC API have been 1403 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1404 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1405 800100. 1406 140720090622: 1408 Layout of struct vnet has changed as routing related variables were 1409 moved to their own Vimage module. Modules need to be recompiled. Bump 1410 __FreeBSD_version to 800099. 1411 141220090619: 1413 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1414 respectively. As long as no more than 16 groups per process are used, 1415 no changes should be visible. When more than 16 groups are used, old 1416 binaries may fail if they call getgroups() or getgrouplist() with 1417 statically sized storage. Recompiling will work around this, but 1418 applications should be modified to use dynamically allocated storage 1419 for group arrays as POSIX.1-2008 does not cap an implementation's 1420 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1421 1422 NFS and portalfs mounts may also be affected as the list of groups is 1423 truncated to 16. Users of NFS who use more than 16 groups, should 1424 take care that negative group permissions are not used on the exported 1425 file systems as they will not be reliable unless a GSSAPI based 1426 authentication method is used. 1427 142820090616: 1429 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1430 option compiles in the support for adaptive spinning for lockmgrs 1431 which want to enable it. The lockinit() function now accepts the flag 1432 LK_ADAPTIVE in order to make the lock object subject to adaptive 1433 spinning when both held in write and read mode. 1434 143520090613: 1436 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1437 changed. User applications that use this ioctl need to be rebuilt. 1438 143920090611: 1440 The layout of struct thread has changed. Kernel and modules need to 1441 be rebuilt. 1442 144320090608: 1444 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1445 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1446 144720090602: 1448 window(1) has been removed from the base system. It can now be 1449 installed from ports. The port is called misc/window. 1450 145120090601: 1452 The way we are storing and accessing `routing table' entries has 1453 changed. Programs reading the FIB, like netstat, need to be 1454 re-compiled. 1455 145620090601: 1457 A new netisr implementation has been added for FreeBSD 8. Network 1458 file system modules, such as igmp, ipdivert, and others, should be 1459 rebuilt. 1460 Bump __FreeBSD_version to 800096. 1461 146220090530: 1463 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1464 more valid. 1465 146620090530: 1467 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1468 Bump __FreeBSD_version to 800094. 1469 147020090529: 1471 Add mnt_xflag field to 'struct mount'. File system modules need to be 1472 rebuilt. 1473 Bump __FreeBSD_version to 800093. 1474 147520090528: 1476 The compiling option ADAPTIVE_SX has been retired while it has been 1477 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1478 The KPI for sx_init_flags() changes as accepting flags: 1479 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1480 been introduced in order to handle the reversed logic. 1481 Bump __FreeBSD_version to 800092. 1482 148320090527: 1484 Add support for hierarchical jails. Remove global securelevel. 1485 Bump __FreeBSD_version to 800091. 1486 148720090523: 1488 The layout of struct vnet_net has changed, therefore modules 1489 need to be rebuilt. 1490 Bump __FreeBSD_version to 800090. 1491 149220090523: 1493 The newly imported zic(8) produces a new format in the output. Please 1494 run tzsetup(8) to install the newly created data to /etc/localtime. 1495 149620090520: 1497 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1498 hw.usb.* and is now consistent again with previous releases. 1499 150020090520: 1501 802.11 monitor mode support was revised and driver api's were changed. 1502 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1503 of DLT_IEEE802_11. No user-visible data structures were changed but 1504 applications that use DLT_IEEE802_11 may require changes. 1505 Bump __FreeBSD_version to 800088. 1506 150720090430: 1508 The layout of the following structs has changed: sysctl_oid, 1509 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1510 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1511 panics may be experienced. World rebuild is required for 1512 correctly checking networking state from userland. 1513 Bump __FreeBSD_version to 800085. 1514 151520090429: 1516 MLDv2 and Source-Specific Multicast (SSM) have been merged 1517 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1518 The implementation of SSM within FreeBSD's IPv6 stack closely 1519 follows the IPv4 implementation. 1520 1521 For kernel developers: 1522 1523 * The most important changes are that the ip6_output() and 1524 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1525 and this lock has been downgraded to a non-recursive mutex. 1526 1527 * As with the changes to the IPv4 stack to support SSM, filtering 1528 of inbound multicast traffic must now be performed by transport 1529 protocols within the IPv6 stack. This does not apply to TCP and 1530 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1531 1532 * The KPIs used by IPv6 multicast are similar to those used by 1533 the IPv4 stack, with the following differences: 1534 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1535 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1536 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1537 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1538 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1539 for MLDv1 have an additional 'timer' argument which is used to 1540 jitter the initial membership report for the solicited-node 1541 multicast membership on-link. 1542 * This is not strictly needed for MLDv2, which already jitters 1543 its report transmissions. However, the 'timer' argument is 1544 preserved in case MLDv1 is active on the interface. 1545 1546 * The KAME linked-list based IPv6 membership implementation has 1547 been refactored to use a vector similar to that used by the IPv4 1548 stack. 1549 Code which maintains a list of its own multicast memberships 1550 internally, e.g. carp, has been updated to reflect the new 1551 semantics. 1552 1553 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1554 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1555 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1556 implementation constraint which needs to be addressed in HEAD. 1557 1558 For application developers: 1559 1560 * The changes are broadly similar to those made for the IPv4 1561 stack. 1562 1563 * The use of IPv4 and IPv6 multicast socket options on the same 1564 socket, using mapped addresses, HAS NOT been tested or supported. 1565 1566 * There are a number of issues with the implementation of various 1567 IPv6 multicast APIs which need to be resolved in the API surface 1568 before the implementation is fully compatible with KAME userland 1569 use, and these are mostly to do with interface index treatment. 1570 1571 * The literature available discusses the use of either the delta / ASM 1572 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1573 using setsourcefilter(3)/getsourcefilter(3). For more information 1574 please refer to RFC 3768, 'Socket Interface Extensions for 1575 Multicast Source Filters'. 1576 1577 * Applications which use the published RFC 3678 APIs should be fine. 1578 1579 For systems administrators: 1580 1581 * The mtest(8) utility has been refactored to support IPv6, in 1582 addition to IPv4. Interface addresses are no longer accepted 1583 as arguments, their names must be used instead. The utility 1584 will map the interface name to its first IPv4 address as 1585 returned by getifaddrs(3). 1586 1587 * The ifmcstat(8) utility has also been updated to print the MLDv2 1588 endpoint state and source filter lists via sysctl(3). 1589 1590 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1591 loopback of IPv6 multicast datagrams by default; it defaults to 1 1592 to preserve the existing behaviour. Disabling multicast loopback is 1593 recommended for optimal system performance. 1594 1595 * The IPv6 MROUTING code has been changed to examine this sysctl 1596 instead of attempting to perform a group lookup before looping 1597 back forwarded datagrams. 1598 1599 Bump __FreeBSD_version to 800084. 1600 160120090422: 1602 Implement low-level Bluetooth HCI API. 1603 Bump __FreeBSD_version to 800083. 1604 160520090419: 1606 The layout of struct malloc_type, used by modules to register new 1607 memory allocation types, has changed. Most modules will need to 1608 be rebuilt or panics may be experienced. 1609 Bump __FreeBSD_version to 800081. 1610 161120090415: 1612 Anticipate overflowing inp_flags - add inp_flags2. 1613 This changes most offsets in inpcb, so checking v4 connection 1614 state will require a world rebuild. 1615 Bump __FreeBSD_version to 800080. 1616 161720090415: 1618 Add an llentry to struct route and struct route_in6. Modules 1619 embedding a struct route will need to be recompiled. 1620 Bump __FreeBSD_version to 800079. 1621 162220090414: 1623 The size of rt_metrics_lite and by extension rtentry has changed. 1624 Networking administration apps will need to be recompiled. 1625 The route command now supports show as an alias for get, weighting 1626 of routes, sticky and nostick flags to alter the behavior of stateful 1627 load balancing. 1628 Bump __FreeBSD_version to 800078. 1629 163020090408: 1631 Do not use Giant for kbdmux(4) locking. This is wrong and 1632 apparently causing more problems than it solves. This will 1633 re-open the issue where interrupt handlers may race with 1634 kbdmux(4) in polling mode. Typical symptoms include (but 1635 not limited to) duplicated and/or missing characters when 1636 low level console functions (such as gets) are used while 1637 interrupts are enabled (for example geli password prompt, 1638 mountroot prompt etc.). Disabling kbdmux(4) may help. 1639 164020090407: 1641 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1642 kernel modules referencing any of the above need to be recompiled. 1643 Bump __FreeBSD_version to 800075. 1644 164520090320: 1646 GEOM_PART has become the default partition slicer for storage devices, 1647 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1648 introduces some changes: 1649 1650 MSDOS/EBR: the devices created from MSDOS extended partition entries 1651 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1652 to devices with offset-based names. fstabs may need to be modified. 1653 1654 BSD: the "geometry does not match label" warning is harmless in most 1655 cases but it points to problems in file system misalignment with 1656 disk geometry. The "c" partition is now implicit, covers the whole 1657 top-level drive and cannot be (mis)used by users. 1658 1659 General: Kernel dumps are now not allowed to be written to devices 1660 whose partition types indicate they are meant to be used for file 1661 systems (or, in case of MSDOS partitions, as something else than 1662 the "386BSD" type). 1663 1664 Most of these changes date approximately from 200812. 1665 166620090319: 1667 The uscanner(4) driver has been removed from the kernel. This follows 1668 Linux removing theirs in 2.6 and making libusb the default interface 1669 (supported by sane). 1670 167120090319: 1672 The multicast forwarding code has been cleaned up. netstat(1) 1673 only relies on KVM now for printing bandwidth upcall meters. 1674 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1675 ip6_mroute_mod respectively. The config(5) options for statically 1676 compiling this code remain the same, i.e. 'options MROUTING'. 1677 167820090315: 1679 Support for the IFF_NEEDSGIANT network interface flag has been 1680 removed, which means that non-MPSAFE network device drivers are no 1681 longer supported. In particular, if_ar, if_sr, and network device 1682 drivers from the old (legacy) USB stack can no longer be built or 1683 used. 1684 168520090313: 1686 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1687 a bunch of new language catalog files have also been added. 1688 This means that some common libc messages are now localized and 1689 they depend on the LC_MESSAGES environmental variable. 1690 169120090313: 1692 The k8temp(4) driver has been renamed to amdtemp(4) since 1693 support for Family 10 and Family 11 CPU families was added. 1694 169520090309: 1696 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1697 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1698 1699 For kernel developers, the most important changes are that the 1700 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1701 and this lock has been downgraded to a non-recursive mutex. 1702 1703 Transport protocols (UDP, Raw IP) are now responsible for filtering 1704 inbound multicast traffic according to group membership and source 1705 filters. The imo_multicast_filter() KPI exists for this purpose. 1706 Transports which do not use multicast (SCTP, TCP) already reject 1707 multicast by default. Forwarding and receive performance may improve 1708 as a mutex acquisition is no longer needed in the ip_input() 1709 low-level input path. in_addmulti() and in_delmulti() are shimmed 1710 to new KPIs which exist to support SSM in-kernel. 1711 1712 For application developers, it is recommended that loopback of 1713 multicast datagrams be disabled for best performance, as this 1714 will still cause the lock to be taken for each looped-back 1715 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1716 be tuned to 0 to disable loopback by default; it defaults to 1 1717 to preserve the existing behaviour. 1718 1719 For systems administrators, to obtain best performance with 1720 multicast reception and multiple groups, it is always recommended 1721 that a card with a suitably precise hash filter is used. Hash 1722 collisions will still result in the lock being taken within the 1723 transport protocol input path to check group membership. 1724 1725 If deploying FreeBSD in an environment with IGMP snooping switches, 1726 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1727 enabled; this forces 224.0.0.0/24 group membership to be announced 1728 via IGMP. 1729 1730 The size of 'struct igmpstat' has changed; netstat needs to be 1731 recompiled to reflect this. 1732 Bump __FreeBSD_version to 800070. 1733 173420090309: 1735 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1736 updated to use it. This requires a buildworld/installworld in order to 1737 update the library and dependencies (usbconfig, etc). Its advisable to 1738 rebuild all ports which uses libusb. More specific directions are given 1739 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1740 libusb are no longer required and can be removed. 1741 174220090302: 1743 A workaround is committed to allow the creation of System V shared 1744 memory segment of size > 2 GB on the 64-bit architectures. 1745 Due to a limitation of the existing ABI, the shm_segsz member 1746 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1747 wrong for large segments. Note that limits must be explicitly 1748 raised to allow such segments to be created. 1749 175020090301: 1751 The layout of struct ifnet has changed, requiring a rebuild of all 1752 network device driver modules. 1753 175420090227: 1755 The /dev handling for the new USB stack has changed, a 1756 buildworld/installworld is required for libusb20. 1757 175820090223: 1759 The new USB2 stack has now been permanently moved in and all kernel and 1760 module names reverted to their previous values (eg, usb, ehci, ohci, 1761 ums, ...). The old usb stack can be compiled in by prefixing the name 1762 with the letter 'o', the old usb modules have been removed. 1763 Updating entry 20090216 for xorg and 20090215 for libmap may still 1764 apply. 1765 176620090217: 1767 The rc.conf(5) option if_up_delay has been renamed to 1768 defaultroute_delay to better reflect its purpose. If you have 1769 customized this setting in /etc/rc.conf you need to update it to 1770 use the new name. 1771 177220090216: 1773 xorg 7.4 wants to configure its input devices via hald which does not 1774 yet work with USB2. If the keyboard/mouse does not work in xorg then 1775 add 1776 Option "AllowEmptyInput" "off" 1777 to your ServerLayout section. This will cause X to use the configured 1778 kbd and mouse sections from your xorg.conf. 1779 178020090215: 1781 The GENERIC kernels for all architectures now default to the new USB2 1782 stack. No kernel config options or code have been removed so if a 1783 problem arises please report it and optionally revert to the old USB 1784 stack. If you are loading USB kernel modules or have a custom kernel 1785 that includes GENERIC then ensure that usb names are also changed over, 1786 eg uftdi -> usb2_serial_ftdi. 1787 1788 Older programs linked against the ports libusb 0.1 need to be 1789 redirected to the new stack's libusb20. /etc/libmap.conf can 1790 be used for this: 1791 # Map old usb library to new one for usb2 stack 1792 libusb-0.1.so.8 libusb20.so.1 1793 179420090209: 1795 All USB ethernet devices now attach as interfaces under the name ueN 1796 (eg. ue0). This is to provide a predictable name as vendors often 1797 change usb chipsets in a product without notice. 1798 179920090203: 1800 The ichsmb(4) driver has been changed to require SMBus slave 1801 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1802 All of the other SMBus controller drivers require left-justified 1803 slave addresses, so this change makes all the drivers provide the 1804 same interface. 1805 180620090201: 1807 INET6 statistics (struct ip6stat) was updated. 1808 netstat(1) needs to be recompiled. 1809 181020090119: 1811 NTFS has been removed from GENERIC kernel on amd64 to match 1812 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1813 will load ntfs.ko module automatically when NTFS support is 1814 actually needed, unless ntfs.ko is not installed or security 1815 level prohibits loading kernel modules. If either is the case, 1816 "options NTFS" has to be added into kernel config. 1817 181820090115: 1819 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1820 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1821 800061. User space tools that rely on the size of struct tcpcb in 1822 tcp_var.h (e.g. sockstat) need to be recompiled. 1823 182420081225: 1825 ng_tty(4) module updated to match the new TTY subsystem. 1826 Due to API change, user-level applications must be updated. 1827 New API support added to mpd5 CVS and expected to be present 1828 in next mpd5.3 release. 1829 183020081219: 1831 With __FreeBSD_version 800060 the makefs tool is part of 1832 the base system (it was a port). 1833 183420081216: 1835 The afdata and ifnet locks have been changed from mutexes to 1836 rwlocks, network modules will need to be re-compiled. 1837 183820081214: 1839 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1840 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1841 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1842 architecture and 40 bytes on 64-bit architecture. The userland 1843 applications "arp" and "ndp" have been updated accordingly. 1844 The output from "netstat -r" shows only routing entries and 1845 none of the L2 information. 1846 184720081130: 1848 __FreeBSD_version 800057 marks the switchover from the 1849 binary ath hal to source code. Users must add the line: 1850 1851 options AH_SUPPORT_AR5416 1852 1853 to their kernel config files when specifying: 1854 1855 device ath_hal 1856 1857 The ath_hal module no longer exists; the code is now compiled 1858 together with the driver in the ath module. It is now 1859 possible to tailor chip support (i.e. reduce the set of chips 1860 and thereby the code size); consult ath_hal(4) for details. 1861 186220081121: 1863 __FreeBSD_version 800054 adds memory barriers to 1864 <machine/atomic.h>, new interfaces to ifnet to facilitate 1865 multiple hardware transmit queues for cards that support 1866 them, and a lock-less ring-buffer implementation to 1867 enable drivers to more efficiently manage queueing of 1868 packets. 1869 187020081117: 1871 A new version of ZFS (version 13) has been merged to -HEAD. 1872 This version has zpool attribute "listsnapshots" off by 1873 default, which means "zfs list" does not show snapshots, 1874 and is the same as Solaris behavior. 1875 187620081028: 1877 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1878 187920081009: 1880 The uhci, ohci, ehci and slhci USB Host controller drivers have 1881 been put into separate modules. If you load the usb module 1882 separately through loader.conf you will need to load the 1883 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1884 controller add the following to loader.conf: 1885 1886 uhci_load="YES" 1887 ehci_load="YES" 1888 188920081009: 1890 The ABI used by the PMC toolset has changed. Please keep 1891 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1892 sync. 1893 189420081009: 1895 atapci kernel module now includes only generic PCI ATA 1896 driver. AHCI driver moved to ataahci kernel module. 1897 All vendor-specific code moved into separate kernel modules: 1898 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1899 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1900 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1901 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1902 190320080820: 1904 The TTY subsystem of the kernel has been replaced by a new 1905 implementation, which provides better scalability and an 1906 improved driver model. Most common drivers have been migrated to 1907 the new TTY subsystem, while others have not. The following 1908 drivers have not yet been ported to the new TTY layer: 1909 1910 PCI/ISA: 1911 cy, digi, rc, rp, sio 1912 1913 USB: 1914 ubser, ucycom 1915 1916 Line disciplines: 1917 ng_h4, ng_tty, ppp, sl, snp 1918 1919 Adding these drivers to your kernel configuration file shall 1920 cause compilation to fail. 1921 192220080818: 1923 ntpd has been upgraded to 4.2.4p5. 1924 192520080801: 1926 OpenSSH has been upgraded to 5.1p1. 1927 1928 For many years, FreeBSD's version of OpenSSH preferred DSA 1929 over RSA for host and user authentication keys. With this 1930 upgrade, we've switched to the vendor's default of RSA over 1931 DSA. This may cause upgraded clients to warn about unknown 1932 host keys even for previously known hosts. Users should 1933 follow the usual procedure for verifying host keys before 1934 accepting the RSA key. 1935 1936 This can be circumvented by setting the "HostKeyAlgorithms" 1937 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1938 command line. 1939 1940 Please note that the sequence of keys offered for 1941 authentication has been changed as well. You may want to 1942 specify IdentityFile in a different order to revert this 1943 behavior. 1944 194520080713: 1946 The sio(4) driver has been removed from the i386 and amd64 1947 kernel configuration files. This means uart(4) is now the 1948 default serial port driver on those platforms as well. 1949 1950 To prevent collisions with the sio(4) driver, the uart(4) driver 1951 uses different names for its device nodes. This means the 1952 onboard serial port will now most likely be called "ttyu0" 1953 instead of "ttyd0". You may need to reconfigure applications to 1954 use the new device names. 1955 1956 When using the serial port as a boot console, be sure to update 1957 /boot/device.hints and /etc/ttys before booting the new kernel. 1958 If you forget to do so, you can still manually specify the hints 1959 at the loader prompt: 1960 1961 set hint.uart.0.at="isa" 1962 set hint.uart.0.port="0x3F8" 1963 set hint.uart.0.flags="0x10" 1964 set hint.uart.0.irq="4" 1965 boot -s 1966 196720080609: 1968 The gpt(8) utility has been removed. Use gpart(8) to partition 1969 disks instead. 1970 197120080603: 1972 The version that Linuxulator emulates was changed from 2.4.2 1973 to 2.6.16. If you experience any problems with Linux binaries 1974 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1975 if it fixes the problem contact emulation mailing list. 1976 197720080525: 1978 ISDN4BSD (I4B) was removed from the src tree. You may need to 1979 update a your kernel configuration and remove relevant entries. 1980 198120080509: 1982 I have checked in code to support multiple routing tables. 1983 See the man pages setfib(1) and setfib(2). 1984 This is a hopefully backwards compatible version, 1985 but to make use of it you need to compile your kernel 1986 with options ROUTETABLES=2 (or more up to 16). 1987 198820080420: 1989 The 802.11 wireless support was redone to enable multi-bss 1990 operation on devices that are capable. The underlying device 1991 is no longer used directly but instead wlanX devices are 1992 cloned with ifconfig. This requires changes to rc.conf files. 1993 For example, change: 1994 ifconfig_ath0="WPA DHCP" 1995 to 1996 wlans_ath0=wlan0 1997 ifconfig_wlan0="WPA DHCP" 1998 see rc.conf(5) for more details. In addition, mergemaster of 1999 /etc/rc.d is highly recommended. Simultaneous update of userland 2000 and kernel wouldn't hurt either. 2001 2002 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2003 modules were merged into the base wlan module. All references 2004 to these modules (e.g. in kernel config files) must be removed. 2005 200620080408: 2007 psm(4) has gained write(2) support in native operation level. 2008 Arbitrary commands can be written to /dev/psm%d and status can 2009 be read back from it. Therefore, an application is responsible 2010 for status validation and error recovery. It is a no-op in 2011 other operation levels. 2012 201320080312: 2014 Support for KSE threading has been removed from the kernel. To 2015 run legacy applications linked against KSE libmap.conf may 2016 be used. The following libmap.conf may be used to ensure 2017 compatibility with any prior release: 2018 2019 libpthread.so.1 libthr.so.1 2020 libpthread.so.2 libthr.so.2 2021 libkse.so.3 libthr.so.3 2022 202320080301: 2024 The layout of struct vmspace has changed. This affects libkvm 2025 and any executables that link against libkvm and use the 2026 kvm_getprocs() function. In particular, but not exclusively, 2027 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2028 The effects are minimal, but it's advisable to upgrade world 2029 nonetheless. 2030 203120080229: 2032 The latest em driver no longer has support in it for the 2033 82575 adapter, this is now moved to the igb driver. The 2034 split was done to make new features that are incompatible 2035 with older hardware easier to do. 2036 203720080220: 2038 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2039 likewise the kernel option is now GEOM_LINUX_LVM. 2040 204120080211: 2042 The default NFS mount mode has changed from UDP to TCP for 2043 increased reliability. If you rely on (insecurely) NFS 2044 mounting across a firewall you may need to update your 2045 firewall rules. 2046 204720080208: 2048 Belatedly note the addition of m_collapse for compacting 2049 mbuf chains. 2050 205120080126: 2052 The fts(3) structures have been changed to use adequate 2053 integer types for their members and so to be able to cope 2054 with huge file trees. The old fts(3) ABI is preserved 2055 through symbol versioning in libc, so third-party binaries 2056 using fts(3) should still work, although they will not take 2057 advantage of the extended types. At the same time, some 2058 third-party software might fail to build after this change 2059 due to unportable assumptions made in its source code about 2060 fts(3) structure members. Such software should be fixed 2061 by its vendor or, in the worst case, in the ports tree. 2062 FreeBSD_version 800015 marks this change for the unlikely 2063 case that a portable fix is impossible. 2064 206520080123: 2066 To upgrade to -current after this date, you must be running 2067 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2068 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2069 207020071128: 2071 The ADAPTIVE_GIANT kernel option has been retired because its 2072 functionality is the default now. 2073 207420071118: 2075 The AT keyboard emulation of sunkbd(4) has been turned on 2076 by default. In order to make the special symbols of the Sun 2077 keyboards driven by sunkbd(4) work under X these now have 2078 to be configured the same way as Sun USB keyboards driven 2079 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2080 2081 Option "XkbLayout" "us" 2082 Option "XkbRules" "xorg" 2083 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2084 208520071024: 2086 It has been decided that it is desirable to provide ABI 2087 backwards compatibility to the FreeBSD 4/5/6 versions of the 2088 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2089 broken with the introduction of PCI domain support (see the 2090 20070930 entry). Unfortunately, this required the ABI of 2091 PCIOCGETCONF to be broken again in order to be able to 2092 provide backwards compatibility to the old version of that 2093 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2094 again. As for prominent ports this affects neither pciutils 2095 nor xorg-server this time, the hal port needs to be rebuilt 2096 however. 2097 209820071020: 2099 The misnamed kthread_create() and friends have been renamed 2100 to kproc_create() etc. Many of the callers already 2101 used kproc_start().. 2102 I will return kthread_create() and friends in a while 2103 with implementations that actually create threads, not procs. 2104 Renaming corresponds with version 800002. 2105 210620071010: 2107 RELENG_7 branched. 2108 2109COMMON ITEMS: 2110 2111 General Notes 2112 ------------- 2113 Avoid using make -j when upgrading. While generally safe, there are 2114 sometimes problems using -j to upgrade. If your upgrade fails with 2115 -j, please try again without -j. From time to time in the past there 2116 have been problems using -j with buildworld and/or installworld. This 2117 is especially true when upgrading between "distant" versions (eg one 2118 that cross a major release boundary or several minor releases, or when 2119 several months have passed on the -current branch). 2120 2121 Sometimes, obscure build problems are the result of environment 2122 poisoning. This can happen because the make utility reads its 2123 environment when searching for values for global variables. To run 2124 your build attempts in an "environmental clean room", prefix all make 2125 commands with 'env -i '. See the env(1) manual page for more details. 2126 2127 When upgrading from one major version to another it is generally best 2128 to upgrade to the latest code in the currently installed branch first, 2129 then do an upgrade to the new branch. This is the best-tested upgrade 2130 path, and has the highest probability of being successful. Please try 2131 this approach before reporting problems with a major version upgrade. 2132 2133 When upgrading a live system, having a root shell around before 2134 installing anything can help undo problems. Not having a root shell 2135 around can lead to problems if pam has changed too much from your 2136 starting point to allow continued authentication after the upgrade. 2137 2138 ZFS notes 2139 --------- 2140 When upgrading the boot ZFS pool to a new version, always follow 2141 these two steps: 2142 2143 1.) recompile and reinstall the ZFS boot loader and boot block 2144 (this is part of "make buildworld" and "make installworld") 2145 2146 2.) update the ZFS boot block on your boot drive 2147 2148 The following example updates the ZFS boot block on the first 2149 partition (freebsd-boot) of a GPT partitioned drive ad0: 2150 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2151 2152 Non-boot pools do not need these updates. 2153 2154 To build a kernel 2155 ----------------- 2156 If you are updating from a prior version of FreeBSD (even one just 2157 a few days old), you should follow this procedure. It is the most 2158 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2159 2160 make kernel-toolchain 2161 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2162 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2163 2164 To test a kernel once 2165 --------------------- 2166 If you just want to boot a kernel once (because you are not sure 2167 if it works, or if you want to boot a known bad kernel to provide 2168 debugging information) run 2169 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2170 nextboot -k testkernel 2171 2172 To just build a kernel when you know that it won't mess you up 2173 -------------------------------------------------------------- 2174 This assumes you are already running a CURRENT system. Replace 2175 ${arch} with the architecture of your machine (e.g. "i386", 2176 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2177 2178 cd src/sys/${arch}/conf 2179 config KERNEL_NAME_HERE 2180 cd ../compile/KERNEL_NAME_HERE 2181 make depend 2182 make 2183 make install 2184 2185 If this fails, go to the "To build a kernel" section. 2186 2187 To rebuild everything and install it on the current system. 2188 ----------------------------------------------------------- 2189 # Note: sometimes if you are running current you gotta do more than 2190 # is listed here if you are upgrading from a really old current. 2191 2192 <make sure you have good level 0 dumps> 2193 make buildworld 2194 make kernel KERNCONF=YOUR_KERNEL_HERE 2195 [1] 2196 <reboot in single user> [3] 2197 mergemaster -p [5] 2198 make installworld 2199 mergemaster -i [4] 2200 make delete-old [6] 2201 <reboot> 2202 2203 To cross-install current onto a separate partition 2204 -------------------------------------------------- 2205 # In this approach we use a separate partition to hold 2206 # current's root, 'usr', and 'var' directories. A partition 2207 # holding "/", "/usr" and "/var" should be about 2GB in 2208 # size. 2209 2210 <make sure you have good level 0 dumps> 2211 <boot into -stable> 2212 make buildworld 2213 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2214 <maybe newfs current's root partition> 2215 <mount current's root partition on directory ${CURRENT_ROOT}> 2216 make installworld DESTDIR=${CURRENT_ROOT} 2217 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2218 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2219 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2220 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2221 <reboot into current> 2222 <do a "native" rebuild/install as described in the previous section> 2223 <maybe install compatibility libraries from ports/misc/compat*> 2224 <reboot> 2225 2226 2227 To upgrade in-place from stable to current 2228 ---------------------------------------------- 2229 <make sure you have good level 0 dumps> 2230 make buildworld [9] 2231 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2232 [1] 2233 <reboot in single user> [3] 2234 mergemaster -p [5] 2235 make installworld 2236 mergemaster -i [4] 2237 make delete-old [6] 2238 <reboot> 2239 2240 Make sure that you've read the UPDATING file to understand the 2241 tweaks to various things you need. At this point in the life 2242 cycle of current, things change often and you are on your own 2243 to cope. The defaults can also change, so please read ALL of 2244 the UPDATING entries. 2245 2246 Also, if you are tracking -current, you must be subscribed to 2247 freebsd-current@freebsd.org. Make sure that before you update 2248 your sources that you have read and understood all the recent 2249 messages there. If in doubt, please track -stable which has 2250 much fewer pitfalls. 2251 2252 [1] If you have third party modules, such as vmware, you 2253 should disable them at this point so they don't crash your 2254 system on reboot. 2255 2256 [3] From the bootblocks, boot -s, and then do 2257 fsck -p 2258 mount -u / 2259 mount -a 2260 cd src 2261 adjkerntz -i # if CMOS is wall time 2262 Also, when doing a major release upgrade, it is required that 2263 you boot into single user mode to do the installworld. 2264 2265 [4] Note: This step is non-optional. Failure to do this step 2266 can result in a significant reduction in the functionality of the 2267 system. Attempting to do it by hand is not recommended and those 2268 that pursue this avenue should read this file carefully, as well 2269 as the archives of freebsd-current and freebsd-hackers mailing lists 2270 for potential gotchas. The -U option is also useful to consider. 2271 See mergemaster(8) for more information. 2272 2273 [5] Usually this step is a noop. However, from time to time 2274 you may need to do this if you get unknown user in the following 2275 step. It never hurts to do it all the time. You may need to 2276 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2277 install) after the buildworld before this step if you last updated 2278 from current before 20130425 or from -stable before 20130430. 2279 2280 [6] This only deletes old files and directories. Old libraries 2281 can be deleted by "make delete-old-libs", but you have to make 2282 sure that no program is using those libraries anymore. 2283 2284 [8] In order to have a kernel that can run the 4.x binaries needed to 2285 do an installworld, you must include the COMPAT_FREEBSD4 option in 2286 your kernel. Failure to do so may leave you with a system that is 2287 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2288 required to run the 5.x binaries on more recent kernels. And so on 2289 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2290 2291 Make sure that you merge any new devices from GENERIC since the 2292 last time you updated your kernel config file. 2293 2294 [9] When checking out sources, you must include the -P flag to have 2295 cvs prune empty directories. 2296 2297 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2298 "?=" instead of the "=" assignment operator, so that buildworld can 2299 override the CPUTYPE if it needs to. 2300 2301 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2302 not on the command line, or in /etc/make.conf. buildworld will 2303 warn if it is improperly defined. 2304FORMAT: 2305 2306This file contains a list, in reverse chronological order, of major 2307breakages in tracking -current. It is not guaranteed to be a complete 2308list of such breakages, and only contains entries since October 10, 2007. 2309If you need to see UPDATING entries from before that date, you will need 2310to fetch an UPDATING file from an older FreeBSD release. 2311 2312Copyright information: 2313 2314Copyright 1998-2009 M.
