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 1920160725 p6 FreeBSD-SA-16:25.bspatch 20 FreeBSD-EN-16:09.freebsd-update 21 22 Fix bspatch heap overflow vulnerability.

They are 69 still available in the security/openssh-portable port. 70 7120151214: 72 r292223 changed the internal interface between the nfsd.ko and 73 nfscommon.ko modules. As such, they must both be upgraded to-gether. 74 __FreeBSD_version has been bumped because of this. 75 7620151113: 77 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 78 Kernel modules isp_2400_multi and isp_2500_multi were removed and 79 should be replaced with isp_2400 and isp_2500 modules respectively. 80 8120150806: 82 The menu.rc and loader.rc files will now be replaced during 83 upgrades. Please migrate local changes to menu.rc.local and 84 loader.rc.local instead. 85 8620151026: 87 NTP has been upgraded to 4.2.8p4. 88 8920151025: 90 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 91 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 92 and devel/kyua to version 0.20+ and adjust any calling code to work 93 with Kyuafile and kyua. 94 9520150823: 96 The polarity of Pulse Per Second (PPS) capture events with the 97 uart(4) driver has been corrected. Prior to this change the PPS 98 "assert" event corresponded to the trailing edge of a positive PPS 99 pulse and the "clear" event was the leading edge of the next pulse. 100 101 As the width of a PPS pulse in a typical GPS receiver is on the 102 order of 1 millisecond, most users will not notice any significant 103 difference with this change. 104 105 Anyone who has compensated for the historical polarity reversal by 106 configuring a negative offset equal to the pulse width will need to 107 remove that workaround. 108 10920150822: 110 From legacy ata(4) driver was removed support for SATA controllers 111 supported by more functional drivers ahci(4), siis(4) and mvs(4). 112 Kernel modules ataahci and ataadaptec were removed completely, 113 replaced by ahci and mvs modules respectively. 114 11520150813: 116 10.2-RELEASE. 117 11820150731: 119 As ZFS requires more kernel stack pages than is the default on some 120 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 121 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 122 123 Please consider using 'options KSTACK_PAGES=X' where X is greater 124 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 125 12620150703: 127 The default Unbound configuration now enables remote control 128 using a local socket. Users who have already enabled the 129 local_unbound service should regenerate their configuration 130 by running "service local_unbound setup" as root. 131 13220150624: 133 An additional fix for the issue described in the 20150614 sendmail 134 entry below has been been committed in revision 284786. 135 13620150615: 137 The fix for the issue described in the 20150614 sendmail entry 138 below has been been committed in revision 284485. The work 139 around described in that entry is no longer needed unless the 140 default setting is overridden by a confDH_PARAMETERS configuration 141 setting of '5' or pointing to a 512 bit DH parameter file. 142 14320150614: 144 The import of openssl to address the FreeBSD-SA-15:10.openssl 145 security advisory includes a change which rejects handshakes 146 with DH parameters below 768 bits. sendmail releases prior 147 to 8.15.2 (not yet released), defaulted to a 512 bit 148 DH parameter setting for client connections. To work around 149 this interoperability, sendmail can be configured to use a 150 2048 bit DH parameter by: 151 152 1. Edit /etc/mail/`hostname`.mc 153 2. If a setting for confDH_PARAMETERS does not exist or 154 exists and is set to a string beginning with '5', 155 replace it with '2'. 156 3. If a setting for confDH_PARAMETERS exists and is set to 157 a file path, create a new file with: 158 openssl dhparam -out /path/to/file 2048 159 4. Rebuild the .cf file: 160 cd /etc/mail/; make; make install 161 5. Restart sendmail: 162 cd /etc/mail/; make restart 163 164 A sendmail patch is coming, at which time this file will be 165 updated. 166 16720150601: 168 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 169 defined in symlink(7); previously symlinks were silently ignored. 170 17120150430: 172 The const qualifier has been removed from iconv(3) to comply with 173 POSIX. The ports tree is aware of this from r384038 onwards. 174 17520141215: 176 At svn r275807, The default linux compat kernel ABI has been adjusted 177 to 2.6.18 in support of the linux-c6 compat ports infrastructure 178 update. If you wish to continue using the linux-f10 compat ports, 179 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 180 encouraged to update their linux-compat packages to linux-c6 during 181 their next update cycle. 182 183 See ports/UPDATING 20141209 and 20141215 on migration to CentOS 6 ports. 184 18520141205: 186 pjdfstest has been integrated into kyua as an opt-in test suite. 187 Please see share/doc/pjdfstest/README for a more details on how to 188 execute it. 189 19020141118: 191 10.1-RELEASE. 192 19320140904: 194 The ofwfb driver, used to provide a graphics console on PowerPC when 195 using vt(4), no longer allows mmap() of all of physical memory. This 196 will prevent Xorg on PowerPC with some ATI graphics cards from 197 initializing properly unless x11-servers/xorg-server is updated to 198 1.12.4_8 or newer. 199 20020140831: 201 The libatf-c and libatf-c++ major versions were downgraded to 0 and 202 1 respectively to match the upstream numbers. They were out of 203 sync because, when they were originally added to FreeBSD, the 204 upstream versions were not respected. These libraries are private 205 and not yet built by default, so renumbering them should be a 206 non-issue. However, unclean source trees will yield broken test 207 programs once the operator executes "make delete-old-libs" after a 208 "make installworld". 209 210 Additionally, the atf-sh binary was made private by moving it into 211 /usr/libexec/. Already-built shell test programs will keep the 212 path to the old binary so they will break after "make delete-old" 213 is run. 214 215 If you are using WITH_TESTS=yes (not the default), wipe the object 216 tree and rebuild from scratch to prevent spurious test failures. 217 This is only needed once: the misnumbered libraries and misplaced 218 binaries have been added to OptionalObsoleteFiles.inc so they will 219 be removed during a clean upgrade. 220 22120140814: 222 The ixgbe tunables now match their sysctl counterparts, for example: 223 hw.ixgbe.enable_aim => hw.ix.enable_aim 224 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 225 22620140801: 227 The NFSv4.1 server committed by r269398 changes the internal 228 function call interfaces used between the NFS and krpc modules. 229 As such, __FreeBSD_version was bumped. 230 23120140729: 232 The default unbound configuration has been modified to address 233 issues with reverse lookups on networks that use private 234 address ranges. If you use the local_unbound service, run 235 "service local_unbound setup" as root to regenerate your 236 configuration, then "service local_unbound reload" to load the 237 new configuration. 238 23920140717: 240 It is no longer necessary to include the dwarf version in your DEBUG 241 options in your kernel config file. The bug that required it to be 242 placed in the config file has bene fixed. DEBUG should now just 243 contain -g. The build system will automatically update things 244 to do the right thing. 245 24620140715: 247 Several ABI breaking changes were merged to CTL and new iSCSI code. 248 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 249 iscsictl need to be rebuilt to work with a new kernel. 250 25120140708: 252 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 253 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 254 which differs from the behaviour controlled by this knob.) 255 25620140608: 257 On i386 and amd64 systems, the onifconsole flag is now set by default 258 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 259 as a login TTY if it is set in the bootloader as an active kernel 260 console. No changes in behavior should result otherwise. To revert to 261 the previous behavior, set ttyu0 to "off" in /etc/ttys. 262 26320140512: 264 Clang and llvm have been upgraded to 3.4.1 release. 265 26620140321: 267 Clang and llvm have been upgraded to 3.4 release. 268 26920140306: 270 If a Makefile in a tests/ directory was auto-generating a Kyuafile 271 instead of providing an explicit one, this would prevent such 272 Makefile from providing its own Kyuafile in the future during 273 NO_CLEAN builds. This has been fixed in the Makefiles but manual 274 intervention is needed to clean an objdir if you use NO_CLEAN: 275 # find /usr/obj -name Kyuafile | xargs rm -f 276 27720140303: 278 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 279 capability mode support. Please note that enabling the feature in 280 kernel is still highly recommended. 281 28220140227: 283 OpenSSH is now built with sandbox support, and will use sandbox as 284 the default privilege separation method. This requires Capsicum 285 capability mode support in kernel. 286 28720140216: 288 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 289 been deprecated and will not be part of FreeBSD 11.0 and later 290 releases. If you use this driver, please consider switching to 291 the nfe(4) driver instead. 292 29320140120: 294 10.0-RELEASE. 295 29620131216: 297 The behavior of gss_pseudo_random() for the krb5 mechanism 298 has changed, for applications requesting a longer random string 299 than produced by the underlying enctype's pseudo-random() function. 300 In particular, the random string produced from a session key of 301 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 302 be different at the 17th octet and later, after this change. 303 The counter used in the PRF+ construction is now encoded as a 304 big-endian integer in accordance with RFC 4402. 305 __FreeBSD_version is bumped to 1000701. 306 30720131108: 308 The WITHOUT_ATF build knob has been removed and its functionality 309 has been subsumed into the more generic WITHOUT_TESTS. If you were 310 using the former to disable the build of the ATF libraries, you 311 should change your settings to use the latter. 312 31320131031: 314 The default version of mtree is nmtree which is obtained from 315 NetBSD. The output is generally the same, but may vary 316 slightly. If you found you need identical output adding 317 "-F freebsd9" to the command line should do the trick. For the 318 time being, the old mtree is available as fmtree. 319 32020131014: 321 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 322 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 323 1.1.4_8 and verify bsdyml not linked in, before running "make 324 delete-old-libs": 325 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 326 or 327 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 328 32920131010: 330 The rc.d/jail script has been updated to support jail(8) 331 configuration file. The "jail_<jname>_*" rc.conf(5) variables 332 for per-jail configuration are automatically converted to 333 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 334 This is transparently backward compatible. See below about some 335 incompatibilities and rc.conf(5) manual page for more details. 336 337 These variables are now deprecated in favor of jail(8) configuration 338 file. One can use "rc.d/jail config <jname>" command to generate 339 a jail(8) configuration file in /var/run/jail.<jname>.conf without 340 running the jail(8) utility. The default pathname of the 341 configuration file is /etc/jail.conf and can be specified by 342 using $jail_conf or $jail_<jname>_conf variables. 343 344 Please note that jail_devfs_ruleset accepts an integer at 345 this moment. Please consider to rewrite the ruleset name 346 with an integer. 347 34820130930: 349 BIND has been removed from the base system. If all you need 350 is a local resolver, simply enable and start the local_unbound 351 service instead. Otherwise, several versions of BIND are 352 available in the ports tree. The dns/bind99 port is one example. 353 354 With this change, nslookup(1) and dig(1) are no longer in the base 355 system. Users should instead use host(1) and drill(1) which are 356 in the base system. Alternatively, nslookup and dig can 357 be obtained by installing the dns/bind-tools port. 358 35920130916: 360 With the addition of unbound(8), a new unbound user is now 361 required during installworld. "mergemaster -p" can be used to 362 add the user prior to installworld, as documented in the handbook. 363 36420130911: 365 OpenSSH is now built with DNSSEC support, and will by default 366 silently trust signed SSHFP records. This can be controlled with 367 the VerifyHostKeyDNS client configuration setting. DNSSEC support 368 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 369 37020130906: 371 The GNU Compiler Collection and C++ standard library (libstdc++) 372 are no longer built by default on platforms where clang is the system 373 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 374 options in src.conf. 375 37620130905: 377 The PROCDESC kernel option is now part of the GENERIC kernel 378 configuration and is required for the rwhod(8) to work. 379 If you are using custom kernel configuration, you should include 380 'options PROCDESC'. 381 38220130905: 383 The API and ABI related to the Capsicum framework was modified 384 in backward incompatible way. The userland libraries and programs 385 have to be recompiled to work with the new kernel. This includes the 386 following libraries and programs, but the whole buildworld is 387 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 388 kdump, procstat, rwho, rwhod, uniq. 389 39020130903: 391 AES-NI intrinsic support has been added to gcc. The AES-NI module 392 has been updated to use this support. A new gcc is required to build 393 the aesni module on both i386 and amd64. 394 39520130821: 396 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 397 Thus "device padlock_rng" and "device rdrand_rng" should be 398 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 399 40020130813: 401 WITH_ICONV has been split into two feature sets. WITH_ICONV now 402 enables just the iconv* functionality and is now on by default. 403 WITH_LIBICONV_COMPAT enables the libiconv api and link time 404 compatability. Set WITHOUT_ICONV to build the old way. 405 If you have been using WITH_ICONV before, you will very likely 406 need to turn on WITH_LIBICONV_COMPAT. 407 40820130806: 409 INVARIANTS option now enables DEBUG for code with OpenSolaris and 410 Illumos origin, including ZFS. If you have INVARIANTS in your 411 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 412 explicitly. 413 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 414 locks if WITNESS option was set. Because that generated a lot of 415 witness(9) reports and all of them were believed to be false 416 positives, this is no longer done. New option OPENSOLARIS_WITNESS 417 can be used to achieve the previous behavior. 418 41920130806: 420 Timer values in IPv6 data structures now use time_uptime instead 421 of time_second. Although this is not a user-visible functional 422 change, userland utilities which directly use them---ndp(8), 423 rtadvd(8), and rtsold(8) in the base system---need to be updated 424 to r253970 or later. 425 42620130802: 427 find -delete can now delete the pathnames given as arguments, 428 instead of only files found below them or if the pathname did 429 not contain any slashes. Formerly, the following error message 430 would result: 431 432 find: -delete: <path>: relative path potentially not safe 433 434 Deleting the pathnames given as arguments can be prevented 435 without error messages using -mindepth 1 or by changing 436 directory and passing "." as argument to find. This works in the 437 old as well as the new version of find. 438 43920130726: 440 Behavior of devfs rules path matching has been changed. 441 Pattern is now always matched against fully qualified devfs 442 path and slash characters must be explicitly matched by 443 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 444 subdirectories must be reviewed. 445 44620130716: 447 The default ARM ABI has changed to the ARM EABI. The old ABI is 448 incompatible with the ARM EABI and all programs and modules will 449 need to be rebuilt to work with a new kernel. 450 451 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 452 453 NOTE: Support for the old ABI will be removed in the future and 454 users are advised to upgrade. 455 45620130709: 457 pkg_install has been disconnected from the build if you really need it 458 you should add WITH_PKGTOOLS in your src.conf(5). 459 46020130709: 461 Most of network statistics structures were changed to be able 462 keep 64-bits counters. Thus all tools, that work with networking 463 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 464 46520130618: 466 Fix a bug that allowed a tracing process (e.g. gdb) to write 467 to a memory-mapped file in the traced process's address space 468 even if neither the traced process nor the tracing process had 469 write access to that file. 470 47120130615: 472 CVS has been removed from the base system. An exact copy 473 of the code is available from the devel/cvs port. 474 47520130613: 476 Some people report the following error after the switch to bmake: 477 478 make: illegal option -- J 479 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 480 ... 481 *** [buildworld] Error code 2 482 483 this likely due to an old instance of make in 484 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 485 which src/Makefile will use that blindly, if it exists, so if 486 you see the above error: 487 488 rm -rf `make -V MAKEPATH` 489 490 should resolve it. 491 49220130516: 493 Use bmake by default. 494 Whereas before one could choose to build with bmake via 495 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 496 make. The goal is to remove these knobs for 10-RELEASE. 497 498 It is worth noting that bmake (like gmake) treats the command 499 line as the unit of failure, rather than statements within the 500 command line. Thus '(cd some/where && dosomething)' is safer 501 than 'cd some/where; dosomething'. The '()' allows consistent 502 behavior in parallel build. 503 50420130429: 505 Fix a bug that allows NFS clients to issue READDIR on files. 506 50720130426: 508 The WITHOUT_IDEA option has been removed because 509 the IDEA patent expired. 510 51120130426: 512 The sysctl which controls TRIM support under ZFS has been renamed 513 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 514 enabled by default. 515 51620130425: 517 The mergemaster command now uses the default MAKEOBJDIRPREFIX 518 rather than creating it's own in the temporary directory in 519 order allow access to bootstrapped versions of tools such as 520 install and mtree. When upgrading from version of FreeBSD where 521 the install command does not support -l, you will need to 522 install a new mergemaster command if mergemaster -p is required. 523 This can be accomplished with the command (cd src/usr.sbin/mergemaster 524 && make install). 525 52620130404: 527 Legacy ATA stack, disabled and replaced by new CAM-based one since 528 FreeBSD 9.0, completely removed from the sources. Kernel modules 529 atadisk and atapi*, user-level tools atacontrol and burncd are 530 removed. Kernel option `options ATA_CAM` is now permanently enabled 531 and removed. 532 53320130319: 534 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 535 and socketpair(2). Software, in particular Kerberos, may 536 automatically detect and use these during building. The resulting 537 binaries will not work on older kernels. 538 53920130308: 540 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 541 information, see the respective 20130304 entry). 542 54320130304: 544 Recent commits to callout(9) changed the size of struct callout, 545 so the KBI is probably heavily disturbed. Also, some functions 546 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 547 by macros. Every kernel module using it won't load, so rebuild 548 is requested. 549 550 The ctl device has been re-enabled in GENERIC for i386 and amd64, 551 but does not initialize by default (because of the new CTL_DISABLE 552 option) to save memory. To re-enable it, remove the CTL_DISABLE 553 option from the kernel config file or set kern.cam.ctl.disable=0 554 in /boot/loader.conf. 555 55620130301: 557 The ctl device has been disabled in GENERIC for i386 and amd64. 558 This was done due to the extra memory being allocated at system 559 initialisation time by the ctl driver which was only used if 560 a CAM target device was created. This makes a FreeBSD system 561 unusable on 128MB or less of RAM. 562 56320130208: 564 A new compression method (lz4) has been merged to -HEAD. Please 565 refer to zpool-features(7) for more information. 566 567 Please refer to the "ZFS notes" section of this file for information 568 on upgrading boot ZFS pools. 569 57020130129: 571 A BSD-licensed patch(1) variant has been added and is installed 572 as bsdpatch, being the GNU version the default patch. 573 To inverse the logic and use the BSD-licensed one as default, 574 while having the GNU version installed as gnupatch, rebuild 575 and install world with the WITH_BSD_PATCH knob set. 576 57720130121: 578 Due to the use of the new -l option to install(1) during build 579 and install, you must take care not to directly set the INSTALL 580 make variable in your /etc/make.conf, /etc/src.conf, or on the 581 command line. If you wish to use the -C flag for all installs 582 you may be able to add INSTALL+=-C to /etc/make.conf or 583 /etc/src.conf. 584 58520130118: 586 The install(1) option -M has changed meaning and now takes an 587 argument that is a file or path to append logs to. In the 588 unlikely event that -M was the last option on the command line 589 and the command line contained at least two files and a target 590 directory the first file will have logs appended to it. The -M 591 option served little practical purpose in the last decade so its 592 use is expected to be extremely rare. 593 59420121223: 595 After switching to Clang as the default compiler some users of ZFS 596 on i386 systems started to experience stack overflow kernel panics. 597 Please consider using 'options KSTACK_PAGES=4' in such configurations. 598 59920121222: 600 GEOM_LABEL now mangles label names read from file system metadata. 601 Mangling affect labels containing spaces, non-printable characters, 602 '%' or '"'. Device names in /etc/fstab and other places may need to 603 be updated. 604 60520121217: 606 By default, only the 10 most recent kernel dumps will be saved. To 607 restore the previous behaviour (no limit on the number of kernel dumps 608 stored in the dump directory) add the following line to /etc/rc.conf: 609 610 savecore_flags="" 611 61220121201: 613 With the addition of auditdistd(8), a new auditdistd user is now 614 required during installworld. "mergemaster -p" can be used to 615 add the user prior to installworld, as documented in the handbook. 616 61720121117: 618 The sin6_scope_id member variable in struct sockaddr_in6 is now 619 filled by the kernel before passing the structure to the userland via 620 sysctl or routing socket. This means the KAME-specific embedded scope 621 id in sin6_addr.s6_addr[2] is always cleared in userland application. 622 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 623 __FreeBSD_version is bumped to 1000025. 624 62520121105: 626 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 627 This means that the world and kernel will be compiled with clang 628 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 629 and /usr/bin/cpp. To disable this behavior and revert to building 630 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 631 of current may need to bootstrap WITHOUT_CLANG first if the clang 632 build fails (its compatibility window doesn't extend to the 9 stable 633 branch point). 634 63520121102: 636 The IPFIREWALL_FORWARD kernel option has been removed. Its 637 functionality now turned on by default. 638 63920121023: 640 The ZERO_COPY_SOCKET kernel option has been removed and 641 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 642 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 643 mechanism which is not safe and may result in kernel crashes. 644 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 645 driver supports disposeable external page sized mbuf storage. 646 Proper replacements for both zero-copy mechanisms are under 647 consideration and will eventually lead to complete removal 648 of the two kernel options. 649 65020121023: 651 The IPv4 network stack has been converted to network byte 652 order. The following modules need to be recompiled together 653 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 654 pf(4), ipfw(4), ng_ipfw(4), stf(4). 655 65620121022: 657 Support for non-MPSAFE filesystems was removed from VFS. The 658 VFS_VERSION was bumped, all filesystem modules shall be 659 recompiled. 660 66120121018: 662 All the non-MPSAFE filesystems have been disconnected from 663 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 664 portalfs, smbfs, xfs. 665 66620121016: 667 The interface cloning API and ABI has changed. The following 668 modules need to be recompiled together with kernel: 669 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 670 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 671 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 672 67320121015: 674 The sdhci driver was split in two parts: sdhci (generic SD Host 675 Controller logic) and sdhci_pci (actual hardware driver). 676 No kernel config modifications are required, but if you 677 load sdhc as a module you must switch to sdhci_pci instead. 678 67920121014: 680 Import the FUSE kernel and userland support into base system. 681 68220121013: 683 The GNU sort(1) program has been removed since the BSD-licensed 684 sort(1) has been the default for quite some time and no serious 685 problems have been reported. The corresponding WITH_GNU_SORT 686 knob has also gone. 687 68820121006: 689 The pfil(9) API/ABI for AF_INET family has been changed. Packet 690 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 691 with new kernel. 692 69320121001: 694 The net80211(4) ABI has been changed to allow for improved driver 695 PS-POLL and power-save support. All wireless drivers need to be 696 recompiled to work with the new kernel. 697 69820120913: 699 The random(4) support for the VIA hardware random number 700 generator (`PADLOCK') is no longer enabled unconditionally. 701 Add the padlock_rng device in the custom kernel config if 702 needed. The GENERIC kernels on i386 and amd64 do include the 703 device, so the change only affects the custom kernel 704 configurations. 705 70620120908: 707 The pf(4) packet filter ABI has been changed. pfctl(8) and 708 snmp_pf module need to be recompiled to work with new kernel. 709 71020120828: 711 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 712 to -HEAD. Pools that have empty_bpobj in active state can not be 713 imported read-write with ZFS implementations that do not support 714 this feature. For more information read the zpool-features(5) 715 manual page. 716 71720120727: 718 The sparc64 ZFS loader has been changed to no longer try to auto- 719 detect ZFS providers based on diskN aliases but now requires these 720 to be explicitly listed in the OFW boot-device environment variable. 721 72220120712: 723 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 724 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 725 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 726 72720120712: 728 The following sysctls and tunables have been renamed for consistency 729 with other variables: 730 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 731 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 732 73320120628: 734 The sort utility has been replaced with BSD sort. For now, GNU sort 735 is also available as "gnusort" or the default can be set back to 736 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 737 installed as "bsdsort". 738 73920120611: 740 A new version of ZFS (pool version 5000) has been merged to -HEAD. 741 Starting with this version the old system of ZFS pool versioning 742 is superseded by "feature flags". This concept enables forward 743 compatibility against certain future changes in functionality of ZFS 744 pools. The first read-only compatible "feature flag" for ZFS pools 745 is named "com.delphix:async_destroy". For more information 746 read the new zpool-features(5) manual page. 747 Please refer to the "ZFS notes" section of this file for information 748 on upgrading boot ZFS pools. 749 75020120417: 751 The malloc(3) implementation embedded in libc now uses sources imported 752 as contrib/jemalloc. The most disruptive API change is to 753 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 754 delete it prior to installworld, and optionally re-create it using the 755 new format after rebooting. See malloc.conf(5) for details 756 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 757 NAMESPACE section). 758 75920120328: 760 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 761 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 762 now spelled mips. This is to aid compatibility with third-party 763 software that expects this naming scheme in uname(3). Little-endian 764 settings are unchanged. If you are updating a big-endian mips64 machine 765 from before this change, you may need to set MACHINE_ARCH=mips64 in 766 your environment before the new build system will recognize your machine. 767 76820120306: 769 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 770 platforms. 771 77220120229: 773 Now unix domain sockets behave "as expected" on nullfs(5). Previously 774 nullfs(5) did not pass through all behaviours to the underlying layer, 775 as a result if we bound to a socket on the lower layer we could connect 776 only to the lower path; if we bound to the upper layer we could connect 777 only to the upper path. The new behavior is one can connect to both the 778 lower and the upper paths regardless what layer path one binds to. 779 78020120211: 781 The getifaddrs upgrade path broken with 20111215 has been restored. 782 If you have upgraded in between 20111215 and 20120209 you need to 783 recompile libc again with your kernel. You still need to recompile 784 world to be able to configure CARP but this restriction already 785 comes from 20111215. 786 78720120114: 788 The set_rcvar() function has been removed from /etc/rc.subr. All 789 base and ports rc.d scripts have been updated, so if you have a 790 port installed with a script in /usr/local/etc/rc.d you can either 791 hand-edit the rcvar= line, or reinstall the port. 792 793 An easy way to handle the mass-update of /etc/rc.d: 794 rm /etc/rc.d/* && mergemaster -i 795 79620120109: 797 panic(9) now stops other CPUs in the SMP systems, disables interrupts 798 on the current CPU and prevents other threads from running. 799 This behavior can be reverted using the kern.stop_scheduler_on_panic 800 tunable/sysctl. 801 The new behavior can be incompatible with kern.sync_on_panic. 802 80320111215: 804 The carp(4) facility has been changed significantly. Configuration 805 of the CARP protocol via ifconfig(8) has changed, as well as format 806 of CARP events submitted to devd(8) has changed. See manual pages 807 for more information. The arpbalance feature of carp(4) is currently 808 not supported anymore. 809 810 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 811 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 812 need to be recompiled. 813 81420111122: 815 The acpi_wmi(4) status device /dev/wmistat has been renamed to 816 /dev/wmistat0. 817 81820111108: 819 The option VFS_ALLOW_NONMPSAFE option has been added in order to 820 explicitely support non-MPSAFE filesystems. 821 It is on by default for all supported platform at this present 822 time. 823 82420111101: 825 The broken amd(4) driver has been replaced with esp(4) in the amd64, 826 i386 and pc98 GENERIC kernel configuration files. 827 82820110930: 829 sysinstall has been removed 830 83120110923: 832 The stable/9 branch created in subversion. This corresponds to the 833 RELENG_9 branch in CVS. 834 83520110913: 836 This commit modifies vfs_register() so that it uses a hash 837 calculation to set vfc_typenum, which is enabled by default. 838 The first time a system is booted after this change, the 839 vfc_typenum values will change for all file systems. The 840 main effect of this is a change to the NFS server file handles 841 for file systems that use vfc_typenum in their fsid, such as ZFS. 842 It will, however, prevent vfc_typenum from changing when file 843 systems are loaded in a different order for subsequent reboots. 844 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 845 until you are ready to remount all NFS clients after a reboot. 846 84720110828: 848 Bump the shared library version numbers for libraries that 849 do not use symbol versioning, have changed the ABI compared 850 to stable/8 and which shared library version was not bumped. 851 Done as part of 9.0-RELEASE cycle. 852 85320110815: 854 During the merge of Capsicum features, the fget(9) KPI was modified. 855 This may require the rebuilding of out-of-tree device drivers -- 856 issues have been reported specifically with the nVidia device driver. 857 __FreeBSD_version is bumped to 900041. 858 859 Also, there is a period between 20110811 and 20110814 where the 860 special devices /dev/{stdin,stdout,stderr} did not work correctly. 861 Building world from a kernel during that window may not work. 862 86320110628: 864 The packet filter (pf) code has been updated to OpenBSD 4.5. 865 You need to update userland tools to be in sync with kernel. 866 This update breaks backward compatibility with earlier pfsync(4) 867 versions. Care must be taken when updating redundant firewall setups. 868 86920110608: 870 The following sysctls and tunables are retired on x86 platforms: 871 machdep.hlt_cpus 872 machdep.hlt_logical_cpus 873 The following sysctl is retired: 874 machdep.hyperthreading_allowed 875 The sysctls were supposed to provide a way to dynamically offline and 876 online selected CPUs on x86 platforms, but the implementation has not 877 been reliable especially with SCHED_ULE scheduler. 878 machdep.hyperthreading_allowed tunable is still available to ignore 879 hyperthreading CPUs at OS level. 880 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 881 where X is an APIC ID of a CPU. Be advised, though, that disabling 882 CPUs in non-uniform fashion will result in non-uniform topology and 883 may lead to sub-optimal system performance with SCHED_ULE, which is 884 a default scheduler. 885 88620110607: 887 cpumask_t type is retired and cpuset_t is used in order to describe 888 a mask of CPUs. 889 89020110531: 891 Changes to ifconfig(8) for dynamic address family detection mandate 892 that you are running a kernel of 20110525 or later. Make sure to 893 follow the update procedure to boot a new kernel before installing 894 world. 895 89620110513: 897 Support for sun4v architecture is officially dropped 898 89920110503: 900 Several KPI breaking changes have been committed to the mii(4) layer, 901 the PHY drivers and consequently some Ethernet drivers using mii(4). 902 This means that miibus.ko and the modules of the affected Ethernet 903 drivers need to be recompiled. 904 905 Note to kernel developers: Given that the OUI bit reversion problem 906 was fixed as part of these changes all mii(4) commits related to OUIs, 907 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 908 handling, no longer can be merged verbatim to stable/8 and previous 909 branches. 910 91120110430: 912 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 913 into their kernel configurations along with 'device pci'. 914 91520110427: 916 The default NFS client is now the new NFS client, so fstype "newnfs" 917 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 918 Although mounts via fstype "nfs" will usually work without userland 919 changes, it is recommended that the mount(8) and mount_nfs(8) 920 commands be rebuilt from sources and that a link to mount_nfs called 921 mount_oldnfs be created. The new client is compiled into the 922 kernel with "options NFSCL" and this is needed for diskless root 923 file systems. The GENERIC kernel configs have been changed to use 924 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 925 To use the regular/old client, you can "mount -t oldnfs ...". For 926 a diskless root file system, you must also include a line like: 927 928 vfs.root.mountfrom="oldnfs:" 929 930 in the boot/loader.conf on the root fs on the NFS server to make 931 a diskless root fs use the old client. 932 93320110424: 934 The GENERIC kernels for all architectures now default to the new 935 CAM-based ATA stack. It means that all legacy ATA drivers were 936 removed and replaced by respective CAM drivers. If you are using 937 ATA device names in /etc/fstab or other places, make sure to update 938 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 939 where 'Y's are the sequential numbers starting from zero for each type 940 in order of detection, unless configured otherwise with tunables, 941 see cam(4)). There will be symbolic links created in /dev/ to map 942 old adX devices to the respective adaY. They should provide basic 943 compatibility for file systems mounting in most cases, but they do 944 not support old user-level APIs and do not have respective providers 945 in GEOM. Consider using updated management tools with new device names. 946 947 It is possible to load devices ahci, ata, siis and mvs as modules, 948 but option ATA_CAM should remain in kernel configuration to make ata 949 module work as CAM driver supporting legacy ATA controllers. Device ata 950 still can be used in modular fashion (atacore + ...). Modules atadisk 951 and atapi* are not used and won't affect operation in ATA_CAM mode. 952 Note that to use CAM-based ATA kernel should include CAM devices 953 scbus, pass, da (or explicitly ada), cd and optionally others. All of 954 them are parts of the cam module. 955 956 ataraid(4) functionality is now supported by the RAID GEOM class. 957 To use it you can load geom_raid kernel module and use graid(8) tool 958 for management. Instead of /dev/arX device names, use /dev/raid/rX. 959 960 No kernel config options or code have been removed, so if a problem 961 arises, please report it and optionally revert to the old ATA stack. 962 In order to do it you can remove from the kernel config: 963 options ATA_CAM 964 device ahci 965 device mvs 966 device siis 967 , and instead add back: 968 device atadisk # ATA disk drives 969 device ataraid # ATA RAID drives 970 device atapicd # ATAPI CDROM drives 971 device atapifd # ATAPI floppy drives 972 device atapist # ATAPI tape drives 973 97420110423: 975 The default NFS server has been changed to the new server, which 976 was referred to as the experimental server. If you need to switch 977 back to the old NFS server, you must now put the "-o" option on 978 both the mountd and nfsd commands. This can be done using the 979 mountd_flags and nfs_server_flags rc.conf variables until an 980 update to the rc scripts is committed, which is coming soon. 981 98220110418: 983 The GNU Objective-C runtime library (libobjc), and other Objective-C 984 related components have been removed from the base system. If you 985 require an Objective-C library, please use one of the available ports. 986 98720110331: 988 ath(4) has been split into bus- and device- modules. if_ath contains 989 the HAL, the TX rate control and the network device code. if_ath_pci 990 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 991 contains the AHB glue. Users need to load both if_ath_pci and if_ath 992 in order to use ath on everything else. 993 994 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 995 need to load if_ath and if_ath_pci for ath(4) operation. 996 99720110314: 998 As part of the replacement of sysinstall, the process of building 999 release media has changed significantly. For details, please re-read 1000 release(7), which has been updated to reflect the new build process. 1001 100220110218: 1003 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1004 is the last available version under GPLv2. It brings a number of new 1005 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1006 4.1 and SSE 4.2), better support for powerpc64, a number of new 1007 directives, and lots of other small improvements. See the ChangeLog 1008 file in contrib/binutils for the full details. 1009 101020110218: 1011 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1012 compliant, and will now use half of hash for authentication. 1013 This will break interoperability with all stacks (including all 1014 actual FreeBSD versions) who implement 1015 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1016 authentication). 1017 The only workaround with such peers is to use another HMAC 1018 algorithm for IPsec ("phase 2") authentication. 1019 102020110207: 1021 Remove the uio_yield prototype and symbol. This function has 1022 been misnamed since it was introduced and should not be 1023 globally exposed with this name. The equivalent functionality 1024 is now available using kern_yield(curthread->td_user_pri). 1025 The function remains undocumented. 1026 102720110112: 1028 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1029 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1030 for scalar sysctls is defined but disabled. Code that needs 1031 UQUAD to pass the type checking that must compile on older 1032 systems where the define is not present can check against 1033 __FreeBSD_version >= 900030. 1034 1035 The system dialog(1) has been replaced with a new version previously 1036 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1037 with the previous version, but the libdialog associated with it has 1038 a largely incompatible API. As such, the original version of libdialog 1039 will be kept temporarily as libodialog, until its base system consumers 1040 are replaced or updated. Bump __FreeBSD_version to 900030. 1041 104220110103: 1043 If you are trying to run make universe on a -stable system, and you get 1044 the following warning: 1045 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1046 unknown. config(8) likely too old." 1047 or something similar to it, then you must upgrade your -stable system 1048 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1049 stable/8) or build the config from the latest stable/8 branch and 1050 install it on your system. 1051 1052 Prior to this date, building a current universe on 8-stable system from 1053 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1054 error in the first kernel build phase. A new config on those old 1055 systems will fix that problem for older versions of -current. 1056 105720101228: 1058 The TCP stack has been modified to allow Khelp modules to interact with 1059 it via helper hook points and store per-connection data in the TCP 1060 control block. Bump __FreeBSD_version to 900029. User space tools that 1061 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1062 be recompiled. 1063 106420101114: 1065 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1066 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1067 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1068 to take advantage of it instead of using custom implementations. This 1069 means that these drivers now no longer unconditionally advertise 1070 support for flow control but only do so if flow control is a selected 1071 media option. This was implemented in the generic support that way in 1072 order to allow flow control to be switched on and off via ifconfig(8) 1073 with the PHY specific default to typically off in order to protect 1074 from unwanted effects. Consequently, if you used flow control with 1075 one of the above mentioned drivers you now need to explicitly enable 1076 it, for example via: 1077 ifconfig bge0 media auto mediaopt flowcontrol 1078 1079 Along with the above mentioned changes generic support for setting 1080 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1081 e1000phy(4) as well as ip1000phy(4) have been converted to take 1082 advantage of it. This means that these drivers now no longer take the 1083 link0 parameter for selecting master mode but the master media option 1084 has to be used instead, for example like in the following: 1085 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1086 1087 Selection of master mode now is also available with all other PHY 1088 drivers supporting 1000baseT. 1089 109020101111: 1091 The TCP stack has received a significant update to add support for 1092 modularised congestion control and generally improve the clarity of 1093 congestion control decisions. Bump __FreeBSD_version to 900025. User 1094 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1095 sockstat) need to be recompiled. 1096 109720101002: 1098 The man(1) utility has been replaced by a new version that no longer 1099 uses /etc/manpath.config. Please consult man.conf(5) for how to 1100 migrate local entries to the new format. 1101 110220100928: 1103 The copyright strings printed by login(1) and sshd(8) at the time of a 1104 new connection have been removed to follow other operating systems and 1105 upstream sshd. 1106 110720100915: 1108 A workaround for a fixed ld bug has been removed in kernel code, 1109 so make sure that your system ld is built from sources after 1110 revision 210245 from 2010-07-19 (r211583 if building head kernel 1111 on stable/8, r211584 for stable/7; both from 2010-08-21). 1112 A symptom of incorrect ld version is different addresses for 1113 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1114 111520100913: 1116 The $ipv6_prefer variable in rc.conf(5) has been split into 1117 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1118 1119 The $ip6addrctl_policy is a variable to choose a pre-defined 1120 address selection policy set by ip6addrctl(8). A value 1121 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1122 default is "AUTO". 1123 1124 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1125 flag (see an entry of 20090926) is set on an interface with no 1126 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1127 security reason. If you want IPv6 link-local address on all 1128 interfaces by default, set this to "YES". 1129 1130 The old ipv6_prefer="YES" is equivalent to 1131 ipv6_activate_all_interfaces="YES" and 1132 ip6addrctl_policy="ipv6_prefer". 1133 113420100913: 1135 DTrace has grown support for userland tracing. Due to this, DTrace is 1136 now i386 and amd64 only. 1137 dtruss(1) is now installed by default on those systems and a new 1138 kernel module is needed for userland tracing: fasttrap. 1139 No changes to your kernel config file are necessary to enable 1140 userland tracing, but you might consider adding 'STRIP=' and 1141 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1142 to have informative userland stack traces in DTrace (ustack). 1143 114420100725: 1145 The acpi_aiboost(4) driver has been removed in favor of the new 1146 aibs(4) driver. You should update your kernel configuration file. 1147 114820100722: 1149 BSD grep has been imported to the base system and it is built by 1150 default. It is completely BSD licensed, highly GNU-compatible, uses 1151 less memory than its GNU counterpart and has a small codebase. 1152 However, it is slower than its GNU counterpart, which is mostly 1153 noticeable for larger searches, for smaller ones it is measurable 1154 but not significant. The reason is complex, the most important factor 1155 is that we lack a modern and efficient regex library and GNU 1156 overcomes this by optimizing the searches internally. Future work 1157 on improving the regex performance is planned, for the meantime, 1158 users that need better performance, can build GNU grep instead by 1159 setting the WITH_GNU_GREP knob. 1160 116120100713: 1162 Due to the import of powerpc64 support, all existing powerpc kernel 1163 configuration files must be updated with a machine directive like this: 1164 machine powerpc powerpc 1165 1166 In addition, an updated config(8) is required to build powerpc kernels 1167 after this change. 1168 116920100713: 1170 A new version of ZFS (version 15) has been merged to -HEAD. 1171 This version uses a python library for the following subcommands: 1172 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1173 For full functionality of these commands the following port must 1174 be installed: sysutils/py-zfs 1175 117620100429: 1177 'vm_page's are now hashed by physical address to an array of mutexes. 1178 Currently this is only used to serialize access to hold_count. Over 1179 time the page queue mutex will be peeled away. This changes the size 1180 of pmap on every architecture. And requires all callers of vm_page_hold 1181 and vm_page_unhold to be updated. 1182 118320100402: 1184 WITH_CTF can now be specified in src.conf (not recommended, there 1185 are some problems with static executables), make.conf (would also 1186 affect ports which do not use GNU make and do not override the 1187 compile targets) or in the kernel config (via "makeoptions 1188 WITH_CTF=yes"). 1189 When WITH_CTF was specified there before this was silently ignored, 1190 so make sure that WITH_CTF is not used in places which could lead 1191 to unwanted behavior. 1192 119320100311: 1194 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1195 to allow 32-bit compatibility on non-x86 platforms. All kernel 1196 configurations on amd64 and ia64 platforms using these options must 1197 be modified accordingly. 1198 119920100113: 1200 The utmp user accounting database has been replaced with utmpx, 1201 the user accounting interface standardized by POSIX. 1202 Unfortunately the semantics of utmp and utmpx don't match, 1203 making it practically impossible to support both interfaces. 1204 The user accounting database is used by tools like finger(1), 1205 last(1), talk(1), w(1) and ac(8). 1206 1207 All applications in the base system use utmpx. This means only 1208 local binaries (e.g. from the ports tree) may still use these 1209 utmp database files. These applications must be rebuilt to make 1210 use of utmpx. 1211 1212 After the system has been upgraded, it is safe to remove the old 1213 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1214 assuming their contents is of no importance anymore. Old wtmp 1215 databases can only be used by last(1) and ac(8) after they have 1216 been converted to the new format using wtmpcvt(1). 1217 121820100108: 1219 Introduce the kernel thread "deadlock resolver" (which can be enabled 1220 via the DEADLKRES option, see NOTES for more details) and the 1221 sleepq_type() function for sleepqueues. 1222 122320091202: 1224 The rc.firewall and rc.firewall6 were unified, and 1225 rc.firewall6 and rc.d/ip6fw were removed. 1226 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1227 variables are obsoleted. Instead, the following new rc 1228 variables are added to rc.d/ipfw: 1229 1230 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1231 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1232 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1233 1234 The meanings correspond to the relevant IPv4 variables. 1235 123620091125: 1237 8.0-RELEASE. 1238 123920091113: 1240 The default terminal emulation for syscons(4) has been changed 1241 from cons25 to xterm on all platforms except pc98. This means 1242 that the /etc/ttys file needs to be updated to ensure correct 1243 operation of applications on the console. 1244 1245 The terminal emulation style can be toggled per window by using 1246 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1247 options can be used to change the compile-time default back to 1248 cons25. 1249 1250 To prevent graphical artifacts, make sure the TERM environment 1251 variable is set to match the terminal emulation that is being 1252 performed by syscons(4). 1253 125420091109: 1255 The layout of the structure ieee80211req_scan_result has changed. 1256 Applications that require wireless scan results (e.g. ifconfig(8)) 1257 from net80211 need to be recompiled. 1258 1259 Applications such as wpa_supplicant(8) may require a full world 1260 build without using NO_CLEAN in order to get synchronized with the 1261 new structure. 1262 126320091025: 1264 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1265 There's one kernel module for each firmware. Adding "device iwnfw" 1266 to the kernel configuration file means including all three firmware 1267 images inside the kernel. If you want to include just the one for 1268 your wireless card, use the devices iwn4965fw, iwn5000fw or 1269 iwn5150fw. 1270 127120090926: 1272 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1273 into rc.d/netif. The changes are the following: 1274 1275 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1276 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1277 Note that both variables need the "inet6" keyword at the head. 1278 1279 Do not set $ipv6_network_interfaces manually if you do not 1280 understand what you are doing. It is not needed in most cases. 1281 1282 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1283 they are obsolete. 1284 1285 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1286 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1287 1288 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1289 all configured interfaces have "inet6 accept_rtadv" in the 1290 $ifconfig_IF_ipv6. These are for backward compatibility. 1291 1292 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1293 functionality of interfaces with no corresponding 1294 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1295 and the default address selection policy of ip6addrctl(8) 1296 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1297 Note that if you want to configure IPv6 functionality on the 1298 disabled interfaces after boot, first you need to clear the flag by 1299 using ifconfig(8) like: 1300 1301 ifconfig em0 inet6 -ifdisabled 1302 1303 If YES, the default address selection policy is set as 1304 IPv6-preferred. 1305 1306 The default value of $ipv6_prefer is NO. 1307 1308 4. If your system need to receive Router Advertisement messages, 1309 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1310 scripts automatically invoke rtsol(8) when the interface becomes 1311 UP. The Router Advertisement messages are used for SLAAC 1312 (State-Less Address AutoConfiguration). 1313 131420090922: 1315 802.11s D3.03 support was committed. This is incompatible with the 1316 previous code, which was based on D3.0. 1317 131820090912: 1319 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1320 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1321 control whether accepting Router Advertisement messages or not. 1322 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1323 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1324 The ifconfig(8) utility now supports these flags. 1325 132620090910: 1327 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1328 mount(8) and -a option for df(1) to see them. 1329 133020090825: 1331 The old tunable hw.bus.devctl_disable has been superseded by 1332 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1333 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1334 is 1000. 1335 133620090813: 1337 Remove the option STOP_NMI. The default action is now to use NMI only 1338 for KDB via the newly introduced function stop_cpus_hard() and 1339 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1340 134120090803: 1342 The stable/8 branch created in subversion. This corresponds to the 1343 RELENG_8 branch in CVS. 1344 134520090719: 1346 Bump the shared library version numbers for all libraries that do not 1347 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1348 __FreeBSD_version to 800105. 1349 135020090714: 1351 Due to changes in the implementation of virtual network stack support, 1352 all network-related kernel modules must be recompiled. As this change 1353 breaks the ABI, bump __FreeBSD_version to 800104. 1354 135520090713: 1356 The TOE interface to the TCP syncache has been modified to remove 1357 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1358 The cxgb driver is the only TOE consumer affected by this change, and 1359 needs to be recompiled along with the kernel. As this change breaks 1360 the ABI, bump __FreeBSD_version to 800103. 1361 136220090712: 1363 Padding has been added to struct tcpcb, sackhint and tcpstat in 1364 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1365 maintaining the ABI. However, this change breaks the ABI, so bump 1366 __FreeBSD_version to 800102. User space tools that rely on the size of 1367 any of these structs (e.g. sockstat) need to be recompiled. 1368 136920090630: 1370 The NFS_LEGACYRPC option has been removed along with the old kernel 1371 RPC implementation that this option selected. Kernel configurations 1372 may need to be adjusted. 1373 137420090629: 1375 The network interface device nodes at /dev/net/<interface> have been 1376 removed. All ioctl operations can be performed the normal way using 1377 routing sockets. The kqueue functionality can generally be replaced 1378 with routing sockets. 1379 138020090628: 1381 The documentation from the FreeBSD Documentation Project (Handbook, 1382 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1383 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1384 138520090624: 1386 The ABI of various structures related to the SYSV IPC API have been 1387 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1388 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1389 800100. 1390 139120090622: 1392 Layout of struct vnet has changed as routing related variables were 1393 moved to their own Vimage module. Modules need to be recompiled. Bump 1394 __FreeBSD_version to 800099. 1395 139620090619: 1397 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1398 respectively. As long as no more than 16 groups per process are used, 1399 no changes should be visible. When more than 16 groups are used, old 1400 binaries may fail if they call getgroups() or getgrouplist() with 1401 statically sized storage. Recompiling will work around this, but 1402 applications should be modified to use dynamically allocated storage 1403 for group arrays as POSIX.1-2008 does not cap an implementation's 1404 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1405 1406 NFS and portalfs mounts may also be affected as the list of groups is 1407 truncated to 16. Users of NFS who use more than 16 groups, should 1408 take care that negative group permissions are not used on the exported 1409 file systems as they will not be reliable unless a GSSAPI based 1410 authentication method is used. 1411 141220090616: 1413 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1414 option compiles in the support for adaptive spinning for lockmgrs 1415 which want to enable it. The lockinit() function now accepts the flag 1416 LK_ADAPTIVE in order to make the lock object subject to adaptive 1417 spinning when both held in write and read mode. 1418 141920090613: 1420 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1421 changed. User applications that use this ioctl need to be rebuilt. 1422 142320090611: 1424 The layout of struct thread has changed. Kernel and modules need to 1425 be rebuilt. 1426 142720090608: 1428 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1429 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1430 143120090602: 1432 window(1) has been removed from the base system. It can now be 1433 installed from ports. The port is called misc/window. 1434 143520090601: 1436 The way we are storing and accessing `routing table' entries has 1437 changed. Programs reading the FIB, like netstat, need to be 1438 re-compiled. 1439 144020090601: 1441 A new netisr implementation has been added for FreeBSD 8. Network 1442 file system modules, such as igmp, ipdivert, and others, should be 1443 rebuilt. 1444 Bump __FreeBSD_version to 800096. 1445 144620090530: 1447 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1448 more valid. 1449 145020090530: 1451 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1452 Bump __FreeBSD_version to 800094. 1453 145420090529: 1455 Add mnt_xflag field to 'struct mount'. File system modules need to be 1456 rebuilt. 1457 Bump __FreeBSD_version to 800093. 1458 145920090528: 1460 The compiling option ADAPTIVE_SX has been retired while it has been 1461 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1462 The KPI for sx_init_flags() changes as accepting flags: 1463 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1464 been introduced in order to handle the reversed logic. 1465 Bump __FreeBSD_version to 800092. 1466 146720090527: 1468 Add support for hierarchical jails. Remove global securelevel. 1469 Bump __FreeBSD_version to 800091. 1470 147120090523: 1472 The layout of struct vnet_net has changed, therefore modules 1473 need to be rebuilt. 1474 Bump __FreeBSD_version to 800090. 1475 147620090523: 1477 The newly imported zic(8) produces a new format in the output. Please 1478 run tzsetup(8) to install the newly created data to /etc/localtime. 1479 148020090520: 1481 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1482 hw.usb.* and is now consistent again with previous releases. 1483 148420090520: 1485 802.11 monitor mode support was revised and driver api's were changed. 1486 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1487 of DLT_IEEE802_11. No user-visible data structures were changed but 1488 applications that use DLT_IEEE802_11 may require changes. 1489 Bump __FreeBSD_version to 800088. 1490 149120090430: 1492 The layout of the following structs has changed: sysctl_oid, 1493 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1494 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1495 panics may be experienced. World rebuild is required for 1496 correctly checking networking state from userland. 1497 Bump __FreeBSD_version to 800085. 1498 149920090429: 1500 MLDv2 and Source-Specific Multicast (SSM) have been merged 1501 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1502 The implementation of SSM within FreeBSD's IPv6 stack closely 1503 follows the IPv4 implementation. 1504 1505 For kernel developers: 1506 1507 * The most important changes are that the ip6_output() and 1508 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1509 and this lock has been downgraded to a non-recursive mutex. 1510 1511 * As with the changes to the IPv4 stack to support SSM, filtering 1512 of inbound multicast traffic must now be performed by transport 1513 protocols within the IPv6 stack. This does not apply to TCP and 1514 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1515 1516 * The KPIs used by IPv6 multicast are similar to those used by 1517 the IPv4 stack, with the following differences: 1518 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1519 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1520 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1521 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1522 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1523 for MLDv1 have an additional 'timer' argument which is used to 1524 jitter the initial membership report for the solicited-node 1525 multicast membership on-link. 1526 * This is not strictly needed for MLDv2, which already jitters 1527 its report transmissions. However, the 'timer' argument is 1528 preserved in case MLDv1 is active on the interface. 1529 1530 * The KAME linked-list based IPv6 membership implementation has 1531 been refactored to use a vector similar to that used by the IPv4 1532 stack. 1533 Code which maintains a list of its own multicast memberships 1534 internally, e.g. carp, has been updated to reflect the new 1535 semantics. 1536 1537 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1538 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1539 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1540 implementation constraint which needs to be addressed in HEAD. 1541 1542 For application developers: 1543 1544 * The changes are broadly similar to those made for the IPv4 1545 stack. 1546 1547 * The use of IPv4 and IPv6 multicast socket options on the same 1548 socket, using mapped addresses, HAS NOT been tested or supported. 1549 1550 * There are a number of issues with the implementation of various 1551 IPv6 multicast APIs which need to be resolved in the API surface 1552 before the implementation is fully compatible with KAME userland 1553 use, and these are mostly to do with interface index treatment. 1554 1555 * The literature available discusses the use of either the delta / ASM 1556 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1557 using setsourcefilter(3)/getsourcefilter(3). For more information 1558 please refer to RFC 3768, 'Socket Interface Extensions for 1559 Multicast Source Filters'. 1560 1561 * Applications which use the published RFC 3678 APIs should be fine. 1562 1563 For systems administrators: 1564 1565 * The mtest(8) utility has been refactored to support IPv6, in 1566 addition to IPv4. Interface addresses are no longer accepted 1567 as arguments, their names must be used instead. The utility 1568 will map the interface name to its first IPv4 address as 1569 returned by getifaddrs(3). 1570 1571 * The ifmcstat(8) utility has also been updated to print the MLDv2 1572 endpoint state and source filter lists via sysctl(3). 1573 1574 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1575 loopback of IPv6 multicast datagrams by default; it defaults to 1 1576 to preserve the existing behaviour. Disabling multicast loopback is 1577 recommended for optimal system performance. 1578 1579 * The IPv6 MROUTING code has been changed to examine this sysctl 1580 instead of attempting to perform a group lookup before looping 1581 back forwarded datagrams. 1582 1583 Bump __FreeBSD_version to 800084. 1584 158520090422: 1586 Implement low-level Bluetooth HCI API. 1587 Bump __FreeBSD_version to 800083. 1588 158920090419: 1590 The layout of struct malloc_type, used by modules to register new 1591 memory allocation types, has changed. Most modules will need to 1592 be rebuilt or panics may be experienced. 1593 Bump __FreeBSD_version to 800081. 1594 159520090415: 1596 Anticipate overflowing inp_flags - add inp_flags2. 1597 This changes most offsets in inpcb, so checking v4 connection 1598 state will require a world rebuild. 1599 Bump __FreeBSD_version to 800080. 1600 160120090415: 1602 Add an llentry to struct route and struct route_in6. Modules 1603 embedding a struct route will need to be recompiled. 1604 Bump __FreeBSD_version to 800079. 1605 160620090414: 1607 The size of rt_metrics_lite and by extension rtentry has changed. 1608 Networking administration apps will need to be recompiled. 1609 The route command now supports show as an alias for get, weighting 1610 of routes, sticky and nostick flags to alter the behavior of stateful 1611 load balancing. 1612 Bump __FreeBSD_version to 800078. 1613 161420090408: 1615 Do not use Giant for kbdmux(4) locking. This is wrong and 1616 apparently causing more problems than it solves. This will 1617 re-open the issue where interrupt handlers may race with 1618 kbdmux(4) in polling mode. Typical symptoms include (but 1619 not limited to) duplicated and/or missing characters when 1620 low level console functions (such as gets) are used while 1621 interrupts are enabled (for example geli password prompt, 1622 mountroot prompt etc.). Disabling kbdmux(4) may help. 1623 162420090407: 1625 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1626 kernel modules referencing any of the above need to be recompiled. 1627 Bump __FreeBSD_version to 800075. 1628 162920090320: 1630 GEOM_PART has become the default partition slicer for storage devices, 1631 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1632 introduces some changes: 1633 1634 MSDOS/EBR: the devices created from MSDOS extended partition entries 1635 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1636 to devices with offset-based names. fstabs may need to be modified. 1637 1638 BSD: the "geometry does not match label" warning is harmless in most 1639 cases but it points to problems in file system misalignment with 1640 disk geometry. The "c" partition is now implicit, covers the whole 1641 top-level drive and cannot be (mis)used by users. 1642 1643 General: Kernel dumps are now not allowed to be written to devices 1644 whose partition types indicate they are meant to be used for file 1645 systems (or, in case of MSDOS partitions, as something else than 1646 the "386BSD" type). 1647 1648 Most of these changes date approximately from 200812. 1649 165020090319: 1651 The uscanner(4) driver has been removed from the kernel. This follows 1652 Linux removing theirs in 2.6 and making libusb the default interface 1653 (supported by sane). 1654 165520090319: 1656 The multicast forwarding code has been cleaned up. netstat(1) 1657 only relies on KVM now for printing bandwidth upcall meters. 1658 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1659 ip6_mroute_mod respectively. The config(5) options for statically 1660 compiling this code remain the same, i.e. 'options MROUTING'. 1661 166220090315: 1663 Support for the IFF_NEEDSGIANT network interface flag has been 1664 removed, which means that non-MPSAFE network device drivers are no 1665 longer supported. In particular, if_ar, if_sr, and network device 1666 drivers from the old (legacy) USB stack can no longer be built or 1667 used. 1668 166920090313: 1670 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1671 a bunch of new language catalog files have also been added. 1672 This means that some common libc messages are now localized and 1673 they depend on the LC_MESSAGES environmental variable. 1674 167520090313: 1676 The k8temp(4) driver has been renamed to amdtemp(4) since 1677 support for Family 10 and Family 11 CPU families was added. 1678 167920090309: 1680 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1681 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1682 1683 For kernel developers, the most important changes are that the 1684 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1685 and this lock has been downgraded to a non-recursive mutex. 1686 1687 Transport protocols (UDP, Raw IP) are now responsible for filtering 1688 inbound multicast traffic according to group membership and source 1689 filters. The imo_multicast_filter() KPI exists for this purpose. 1690 Transports which do not use multicast (SCTP, TCP) already reject 1691 multicast by default. Forwarding and receive performance may improve 1692 as a mutex acquisition is no longer needed in the ip_input() 1693 low-level input path. in_addmulti() and in_delmulti() are shimmed 1694 to new KPIs which exist to support SSM in-kernel. 1695 1696 For application developers, it is recommended that loopback of 1697 multicast datagrams be disabled for best performance, as this 1698 will still cause the lock to be taken for each looped-back 1699 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1700 be tuned to 0 to disable loopback by default; it defaults to 1 1701 to preserve the existing behaviour. 1702 1703 For systems administrators, to obtain best performance with 1704 multicast reception and multiple groups, it is always recommended 1705 that a card with a suitably precise hash filter is used. Hash 1706 collisions will still result in the lock being taken within the 1707 transport protocol input path to check group membership. 1708 1709 If deploying FreeBSD in an environment with IGMP snooping switches, 1710 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1711 enabled; this forces 224.0.0.0/24 group membership to be announced 1712 via IGMP. 1713 1714 The size of 'struct igmpstat' has changed; netstat needs to be 1715 recompiled to reflect this. 1716 Bump __FreeBSD_version to 800070. 1717 171820090309: 1719 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1720 updated to use it. This requires a buildworld/installworld in order to 1721 update the library and dependencies (usbconfig, etc). Its advisable to 1722 rebuild all ports which uses libusb. More specific directions are given 1723 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1724 libusb are no longer required and can be removed. 1725 172620090302: 1727 A workaround is committed to allow the creation of System V shared 1728 memory segment of size > 2 GB on the 64-bit architectures. 1729 Due to a limitation of the existing ABI, the shm_segsz member 1730 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1731 wrong for large segments. Note that limits must be explicitly 1732 raised to allow such segments to be created. 1733 173420090301: 1735 The layout of struct ifnet has changed, requiring a rebuild of all 1736 network device driver modules. 1737 173820090227: 1739 The /dev handling for the new USB stack has changed, a 1740 buildworld/installworld is required for libusb20. 1741 174220090223: 1743 The new USB2 stack has now been permanently moved in and all kernel and 1744 module names reverted to their previous values (eg, usb, ehci, ohci, 1745 ums, ...). The old usb stack can be compiled in by prefixing the name 1746 with the letter 'o', the old usb modules have been removed. 1747 Updating entry 20090216 for xorg and 20090215 for libmap may still 1748 apply. 1749 175020090217: 1751 The rc.conf(5) option if_up_delay has been renamed to 1752 defaultroute_delay to better reflect its purpose. If you have 1753 customized this setting in /etc/rc.conf you need to update it to 1754 use the new name. 1755 175620090216: 1757 xorg 7.4 wants to configure its input devices via hald which does not 1758 yet work with USB2. If the keyboard/mouse does not work in xorg then 1759 add 1760 Option "AllowEmptyInput" "off" 1761 to your ServerLayout section. This will cause X to use the configured 1762 kbd and mouse sections from your xorg.conf. 1763 176420090215: 1765 The GENERIC kernels for all architectures now default to the new USB2 1766 stack. No kernel config options or code have been removed so if a 1767 problem arises please report it and optionally revert to the old USB 1768 stack. If you are loading USB kernel modules or have a custom kernel 1769 that includes GENERIC then ensure that usb names are also changed over, 1770 eg uftdi -> usb2_serial_ftdi. 1771 1772 Older programs linked against the ports libusb 0.1 need to be 1773 redirected to the new stack's libusb20. /etc/libmap.conf can 1774 be used for this: 1775 # Map old usb library to new one for usb2 stack 1776 libusb-0.1.so.8 libusb20.so.1 1777 177820090209: 1779 All USB ethernet devices now attach as interfaces under the name ueN 1780 (eg. ue0). This is to provide a predictable name as vendors often 1781 change usb chipsets in a product without notice. 1782 178320090203: 1784 The ichsmb(4) driver has been changed to require SMBus slave 1785 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1786 All of the other SMBus controller drivers require left-justified 1787 slave addresses, so this change makes all the drivers provide the 1788 same interface. 1789 179020090201: 1791 INET6 statistics (struct ip6stat) was updated. 1792 netstat(1) needs to be recompiled. 1793 179420090119: 1795 NTFS has been removed from GENERIC kernel on amd64 to match 1796 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1797 will load ntfs.ko module automatically when NTFS support is 1798 actually needed, unless ntfs.ko is not installed or security 1799 level prohibits loading kernel modules. If either is the case, 1800 "options NTFS" has to be added into kernel config. 1801 180220090115: 1803 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1804 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1805 800061. User space tools that rely on the size of struct tcpcb in 1806 tcp_var.h (e.g. sockstat) need to be recompiled. 1807 180820081225: 1809 ng_tty(4) module updated to match the new TTY subsystem. 1810 Due to API change, user-level applications must be updated. 1811 New API support added to mpd5 CVS and expected to be present 1812 in next mpd5.3 release. 1813 181420081219: 1815 With __FreeBSD_version 800060 the makefs tool is part of 1816 the base system (it was a port). 1817 181820081216: 1819 The afdata and ifnet locks have been changed from mutexes to 1820 rwlocks, network modules will need to be re-compiled. 1821 182220081214: 1823 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1824 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1825 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1826 architecture and 40 bytes on 64-bit architecture. The userland 1827 applications "arp" and "ndp" have been updated accordingly. 1828 The output from "netstat -r" shows only routing entries and 1829 none of the L2 information. 1830 183120081130: 1832 __FreeBSD_version 800057 marks the switchover from the 1833 binary ath hal to source code. Users must add the line: 1834 1835 options AH_SUPPORT_AR5416 1836 1837 to their kernel config files when specifying: 1838 1839 device ath_hal 1840 1841 The ath_hal module no longer exists; the code is now compiled 1842 together with the driver in the ath module. It is now 1843 possible to tailor chip support (i.e. reduce the set of chips 1844 and thereby the code size); consult ath_hal(4) for details. 1845 184620081121: 1847 __FreeBSD_version 800054 adds memory barriers to 1848 <machine/atomic.h>, new interfaces to ifnet to facilitate 1849 multiple hardware transmit queues for cards that support 1850 them, and a lock-less ring-buffer implementation to 1851 enable drivers to more efficiently manage queueing of 1852 packets. 1853 185420081117: 1855 A new version of ZFS (version 13) has been merged to -HEAD. 1856 This version has zpool attribute "listsnapshots" off by 1857 default, which means "zfs list" does not show snapshots, 1858 and is the same as Solaris behavior. 1859 186020081028: 1861 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1862 186320081009: 1864 The uhci, ohci, ehci and slhci USB Host controller drivers have 1865 been put into separate modules. If you load the usb module 1866 separately through loader.conf you will need to load the 1867 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1868 controller add the following to loader.conf: 1869 1870 uhci_load="YES" 1871 ehci_load="YES" 1872 187320081009: 1874 The ABI used by the PMC toolset has changed. Please keep 1875 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1876 sync. 1877 187820081009: 1879 atapci kernel module now includes only generic PCI ATA 1880 driver. AHCI driver moved to ataahci kernel module. 1881 All vendor-specific code moved into separate kernel modules: 1882 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1883 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1884 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1885 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1886 188720080820: 1888 The TTY subsystem of the kernel has been replaced by a new 1889 implementation, which provides better scalability and an 1890 improved driver model. Most common drivers have been migrated to 1891 the new TTY subsystem, while others have not. The following 1892 drivers have not yet been ported to the new TTY layer: 1893 1894 PCI/ISA: 1895 cy, digi, rc, rp, sio 1896 1897 USB: 1898 ubser, ucycom 1899 1900 Line disciplines: 1901 ng_h4, ng_tty, ppp, sl, snp 1902 1903 Adding these drivers to your kernel configuration file shall 1904 cause compilation to fail. 1905 190620080818: 1907 ntpd has been upgraded to 4.2.4p5. 1908 190920080801: 1910 OpenSSH has been upgraded to 5.1p1. 1911 1912 For many years, FreeBSD's version of OpenSSH preferred DSA 1913 over RSA for host and user authentication keys. With this 1914 upgrade, we've switched to the vendor's default of RSA over 1915 DSA. This may cause upgraded clients to warn about unknown 1916 host keys even for previously known hosts. Users should 1917 follow the usual procedure for verifying host keys before 1918 accepting the RSA key. 1919 1920 This can be circumvented by setting the "HostKeyAlgorithms" 1921 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1922 command line. 1923 1924 Please note that the sequence of keys offered for 1925 authentication has been changed as well. You may want to 1926 specify IdentityFile in a different order to revert this 1927 behavior. 1928 192920080713: 1930 The sio(4) driver has been removed from the i386 and amd64 1931 kernel configuration files. This means uart(4) is now the 1932 default serial port driver on those platforms as well. 1933 1934 To prevent collisions with the sio(4) driver, the uart(4) driver 1935 uses different names for its device nodes. This means the 1936 onboard serial port will now most likely be called "ttyu0" 1937 instead of "ttyd0". You may need to reconfigure applications to 1938 use the new device names. 1939 1940 When using the serial port as a boot console, be sure to update 1941 /boot/device.hints and /etc/ttys before booting the new kernel. 1942 If you forget to do so, you can still manually specify the hints 1943 at the loader prompt: 1944 1945 set hint.uart.0.at="isa" 1946 set hint.uart.0.port="0x3F8" 1947 set hint.uart.0.flags="0x10" 1948 set hint.uart.0.irq="4" 1949 boot -s 1950 195120080609: 1952 The gpt(8) utility has been removed. Use gpart(8) to partition 1953 disks instead. 1954 195520080603: 1956 The version that Linuxulator emulates was changed from 2.4.2 1957 to 2.6.16. If you experience any problems with Linux binaries 1958 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1959 if it fixes the problem contact emulation mailing list. 1960 196120080525: 1962 ISDN4BSD (I4B) was removed from the src tree. You may need to 1963 update a your kernel configuration and remove relevant entries. 1964 196520080509: 1966 I have checked in code to support multiple routing tables. 1967 See the man pages setfib(1) and setfib(2). 1968 This is a hopefully backwards compatible version, 1969 but to make use of it you need to compile your kernel 1970 with options ROUTETABLES=2 (or more up to 16). 1971 197220080420: 1973 The 802.11 wireless support was redone to enable multi-bss 1974 operation on devices that are capable. The underlying device 1975 is no longer used directly but instead wlanX devices are 1976 cloned with ifconfig. This requires changes to rc.conf files. 1977 For example, change: 1978 ifconfig_ath0="WPA DHCP" 1979 to 1980 wlans_ath0=wlan0 1981 ifconfig_wlan0="WPA DHCP" 1982 see rc.conf(5) for more details. In addition, mergemaster of 1983 /etc/rc.d is highly recommended. Simultaneous update of userland 1984 and kernel wouldn't hurt either. 1985 1986 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1987 modules were merged into the base wlan module. All references 1988 to these modules (e.g. in kernel config files) must be removed. 1989 199020080408: 1991 psm(4) has gained write(2) support in native operation level. 1992 Arbitrary commands can be written to /dev/psm%d and status can 1993 be read back from it. Therefore, an application is responsible 1994 for status validation and error recovery. It is a no-op in 1995 other operation levels. 1996 199720080312: 1998 Support for KSE threading has been removed from the kernel. To 1999 run legacy applications linked against KSE libmap.conf may 2000 be used. The following libmap.conf may be used to ensure 2001 compatibility with any prior release: 2002 2003 libpthread.so.1 libthr.so.1 2004 libpthread.so.2 libthr.so.2 2005 libkse.so.3 libthr.so.3 2006 200720080301: 2008 The layout of struct vmspace has changed. This affects libkvm 2009 and any executables that link against libkvm and use the 2010 kvm_getprocs() function. In particular, but not exclusively, 2011 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2012 The effects are minimal, but it's advisable to upgrade world 2013 nonetheless. 2014 201520080229: 2016 The latest em driver no longer has support in it for the 2017 82575 adapter, this is now moved to the igb driver. The 2018 split was done to make new features that are incompatible 2019 with older hardware easier to do. 2020 202120080220: 2022 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2023 likewise the kernel option is now GEOM_LINUX_LVM. 2024 202520080211: 2026 The default NFS mount mode has changed from UDP to TCP for 2027 increased reliability. If you rely on (insecurely) NFS 2028 mounting across a firewall you may need to update your 2029 firewall rules. 2030 203120080208: 2032 Belatedly note the addition of m_collapse for compacting 2033 mbuf chains. 2034 203520080126: 2036 The fts(3) structures have been changed to use adequate 2037 integer types for their members and so to be able to cope 2038 with huge file trees. The old fts(3) ABI is preserved 2039 through symbol versioning in libc, so third-party binaries 2040 using fts(3) should still work, although they will not take 2041 advantage of the extended types. At the same time, some 2042 third-party software might fail to build after this change 2043 due to unportable assumptions made in its source code about 2044 fts(3) structure members. Such software should be fixed 2045 by its vendor or, in the worst case, in the ports tree. 2046 FreeBSD_version 800015 marks this change for the unlikely 2047 case that a portable fix is impossible. 2048 204920080123: 2050 To upgrade to -current after this date, you must be running 2051 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2052 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2053 205420071128: 2055 The ADAPTIVE_GIANT kernel option has been retired because its 2056 functionality is the default now. 2057 205820071118: 2059 The AT keyboard emulation of sunkbd(4) has been turned on 2060 by default. In order to make the special symbols of the Sun 2061 keyboards driven by sunkbd(4) work under X these now have 2062 to be configured the same way as Sun USB keyboards driven 2063 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2064 2065 Option "XkbLayout" "us" 2066 Option "XkbRules" "xorg" 2067 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2068 206920071024: 2070 It has been decided that it is desirable to provide ABI 2071 backwards compatibility to the FreeBSD 4/5/6 versions of the 2072 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2073 broken with the introduction of PCI domain support (see the 2074 20070930 entry). Unfortunately, this required the ABI of 2075 PCIOCGETCONF to be broken again in order to be able to 2076 provide backwards compatibility to the old version of that 2077 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2078 again. As for prominent ports this affects neither pciutils 2079 nor xorg-server this time, the hal port needs to be rebuilt 2080 however. 2081 208220071020: 2083 The misnamed kthread_create() and friends have been renamed 2084 to kproc_create() etc. Many of the callers already 2085 used kproc_start().. 2086 I will return kthread_create() and friends in a while 2087 with implementations that actually create threads, not procs. 2088 Renaming corresponds with version 800002. 2089 209020071010: 2091 RELENG_7 branched. 2092 2093COMMON ITEMS: 2094 2095 General Notes 2096 ------------- 2097 Avoid using make -j when upgrading. While generally safe, there are 2098 sometimes problems using -j to upgrade. If your upgrade fails with 2099 -j, please try again without -j. From time to time in the past there 2100 have been problems using -j with buildworld and/or installworld. This 2101 is especially true when upgrading between "distant" versions (eg one 2102 that cross a major release boundary or several minor releases, or when 2103 several months have passed on the -current branch). 2104 2105 Sometimes, obscure build problems are the result of environment 2106 poisoning. This can happen because the make utility reads its 2107 environment when searching for values for global variables. To run 2108 your build attempts in an "environmental clean room", prefix all make 2109 commands with 'env -i '. See the env(1) manual page for more details. 2110 2111 When upgrading from one major version to another it is generally best 2112 to upgrade to the latest code in the currently installed branch first, 2113 then do an upgrade to the new branch. This is the best-tested upgrade 2114 path, and has the highest probability of being successful. Please try 2115 this approach before reporting problems with a major version upgrade. 2116 2117 When upgrading a live system, having a root shell around before 2118 installing anything can help undo problems. Not having a root shell 2119 around can lead to problems if pam has changed too much from your 2120 starting point to allow continued authentication after the upgrade. 2121 2122 ZFS notes 2123 --------- 2124 When upgrading the boot ZFS pool to a new version, always follow 2125 these two steps: 2126 2127 1.) recompile and reinstall the ZFS boot loader and boot block 2128 (this is part of "make buildworld" and "make installworld") 2129 2130 2.) update the ZFS boot block on your boot drive 2131 2132 The following example updates the ZFS boot block on the first 2133 partition (freebsd-boot) of a GPT partitioned drive ad0: 2134 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2135 2136 Non-boot pools do not need these updates. 2137 2138 To build a kernel 2139 ----------------- 2140 If you are updating from a prior version of FreeBSD (even one just 2141 a few days old), you should follow this procedure. It is the most 2142 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2143 2144 make kernel-toolchain 2145 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2146 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2147 2148 To test a kernel once 2149 --------------------- 2150 If you just want to boot a kernel once (because you are not sure 2151 if it works, or if you want to boot a known bad kernel to provide 2152 debugging information) run 2153 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2154 nextboot -k testkernel 2155 2156 To just build a kernel when you know that it won't mess you up 2157 -------------------------------------------------------------- 2158 This assumes you are already running a CURRENT system. Replace 2159 ${arch} with the architecture of your machine (e.g. "i386", 2160 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2161 2162 cd src/sys/${arch}/conf 2163 config KERNEL_NAME_HERE 2164 cd ../compile/KERNEL_NAME_HERE 2165 make depend 2166 make 2167 make install 2168 2169 If this fails, go to the "To build a kernel" section. 2170 2171 To rebuild everything and install it on the current system. 2172 ----------------------------------------------------------- 2173 # Note: sometimes if you are running current you gotta do more than 2174 # is listed here if you are upgrading from a really old current. 2175 2176 <make sure you have good level 0 dumps> 2177 make buildworld 2178 make kernel KERNCONF=YOUR_KERNEL_HERE 2179 [1] 2180 <reboot in single user> [3] 2181 mergemaster -p [5] 2182 make installworld 2183 mergemaster -i [4] 2184 make delete-old [6] 2185 <reboot> 2186 2187 To cross-install current onto a separate partition 2188 -------------------------------------------------- 2189 # In this approach we use a separate partition to hold 2190 # current's root, 'usr', and 'var' directories. A partition 2191 # holding "/", "/usr" and "/var" should be about 2GB in 2192 # size. 2193 2194 <make sure you have good level 0 dumps> 2195 <boot into -stable> 2196 make buildworld 2197 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2198 <maybe newfs current's root partition> 2199 <mount current's root partition on directory ${CURRENT_ROOT}> 2200 make installworld DESTDIR=${CURRENT_ROOT} 2201 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2202 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2203 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2204 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2205 <reboot into current> 2206 <do a "native" rebuild/install as described in the previous section> 2207 <maybe install compatibility libraries from ports/misc/compat*> 2208 <reboot> 2209 2210 2211 To upgrade in-place from stable to current 2212 ---------------------------------------------- 2213 <make sure you have good level 0 dumps> 2214 make buildworld [9] 2215 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2216 [1] 2217 <reboot in single user> [3] 2218 mergemaster -p [5] 2219 make installworld 2220 mergemaster -i [4] 2221 make delete-old [6] 2222 <reboot> 2223 2224 Make sure that you've read the UPDATING file to understand the 2225 tweaks to various things you need. At this point in the life 2226 cycle of current, things change often and you are on your own 2227 to cope. The defaults can also change, so please read ALL of 2228 the UPDATING entries. 2229 2230 Also, if you are tracking -current, you must be subscribed to 2231 freebsd-current@freebsd.org. Make sure that before you update 2232 your sources that you have read and understood all the recent 2233 messages there. If in doubt, please track -stable which has 2234 much fewer pitfalls. 2235 2236 [1] If you have third party modules, such as vmware, you 2237 should disable them at this point so they don't crash your 2238 system on reboot. 2239 2240 [3] From the bootblocks, boot -s, and then do 2241 fsck -p 2242 mount -u / 2243 mount -a 2244 cd src 2245 adjkerntz -i # if CMOS is wall time 2246 Also, when doing a major release upgrade, it is required that 2247 you boot into single user mode to do the installworld. 2248 2249 [4] Note: This step is non-optional. Failure to do this step 2250 can result in a significant reduction in the functionality of the 2251 system. Attempting to do it by hand is not recommended and those 2252 that pursue this avenue should read this file carefully, as well 2253 as the archives of freebsd-current and freebsd-hackers mailing lists 2254 for potential gotchas. The -U option is also useful to consider. 2255 See mergemaster(8) for more information. 2256 2257 [5] Usually this step is a noop. However, from time to time 2258 you may need to do this if you get unknown user in the following 2259 step. It never hurts to do it all the time. You may need to 2260 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2261 install) after the buildworld before this step if you last updated 2262 from current before 20130425 or from -stable before 20130430. 2263 2264 [6] This only deletes old files and directories. Old libraries 2265 can be deleted by "make delete-old-libs", but you have to make 2266 sure that no program is using those libraries anymore. 2267 2268 [8] In order to have a kernel that can run the 4.x binaries needed to 2269 do an installworld, you must include the COMPAT_FREEBSD4 option in 2270 your kernel. Failure to do so may leave you with a system that is 2271 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2272 required to run the 5.x binaries on more recent kernels. And so on 2273 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2274 2275 Make sure that you merge any new devices from GENERIC since the 2276 last time you updated your kernel config file. 2277 2278 [9] When checking out sources, you must include the -P flag to have 2279 cvs prune empty directories. 2280 2281 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2282 "?=" instead of the "=" assignment operator, so that buildworld can 2283 override the CPUTYPE if it needs to. 2284 2285 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2286 not on the command line, or in /etc/make.conf. buildworld will 2287 warn if it is improperly defined. 2288FORMAT: 2289 2290This file contains a list, in reverse chronological order, of major 2291breakages in tracking -current. It is not guaranteed to be a complete 2292list of such breakages, and only contains entries since October 10, 2007. 2293If you need to see UPDATING entries from before that date, you will need 2294to fetch an UPDATING file from an older FreeBSD release. 2295 2296Copyright information: 2297 2298Copyright 1998-2009 M.
