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 1920160517 p17 FreeBSD-SA-16:18.atkbd 20 FreeBSD-SA-16:19.sendmsg 21 22 Fix buffer overflow in keyboard driver.

[EN-15:13] 151 15220150813: 153 10.2-RELEASE. 154 15520150703: 156 The default Unbound configuration now enables remote control 157 using a local socket. Users who have already enabled the 158 local_unbound service should regenerate their configuration 159 by running "service local_unbound setup" as root. 160 16120150624: 162 An additional fix for the issue described in the 20150614 sendmail 163 entry below has been been committed in revision 284786. 164 16520150615: 166 The fix for the issue described in the 20150614 sendmail entry 167 below has been been committed in revision 284485. The work 168 around described in that entry is no longer needed unless the 169 default setting is overridden by a confDH_PARAMETERS configuration 170 setting of '5' or pointing to a 512 bit DH parameter file. 171 17220150614: 173 The import of openssl to address the FreeBSD-SA-15:10.openssl 174 security advisory includes a change which rejects handshakes 175 with DH parameters below 768 bits. sendmail releases prior 176 to 8.15.2 (not yet released), defaulted to a 512 bit 177 DH parameter setting for client connections. To work around 178 this interoperability, sendmail can be configured to use a 179 2048 bit DH parameter by: 180 181 1. Edit /etc/mail/`hostname`.mc 182 2. If a setting for confDH_PARAMETERS does not exist or 183 exists and is set to a string beginning with '5', 184 replace it with '2'. 185 3. If a setting for confDH_PARAMETERS exists and is set to 186 a file path, create a new file with: 187 openssl dhparam -out /path/to/file 2048 188 4. Rebuild the .cf file: 189 cd /etc/mail/; make; make install 190 5. Restart sendmail: 191 cd /etc/mail/; make restart 192 193 A sendmail patch is coming, at which time this file will be 194 updated. 195 19620150601: 197 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 198 defined in symlink(7); previously symlinks were silently ignored. 199 20020150430: 201 The const qualifier has been removed from iconv(3) to comply with 202 POSIX. The ports tree is aware of this from r384038 onwards. 203 20420141215: 205 At svn r275807, The default linux compat kernel ABI has been adjusted 206 to 2.6.18 in support of the linux-c6 compat ports infrastructure 207 update. If you wish to continue using the linux-f10 compat ports, 208 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 209 encouraged to update their linux-compat packages to linux-c6 during 210 their next update cycle. 211 212 See ports/UPDATING 20141209 and 20141215 on migration to CentOS 6 ports. 213 21420141205: 215 pjdfstest has been integrated into kyua as an opt-in test suite. 216 Please see share/doc/pjdfstest/README for a more details on how to 217 execute it. 218 21920141118: 220 10.1-RELEASE. 221 22220140904: 223 The ofwfb driver, used to provide a graphics console on PowerPC when 224 using vt(4), no longer allows mmap() of all of physical memory. This 225 will prevent Xorg on PowerPC with some ATI graphics cards from 226 initializing properly unless x11-servers/xorg-server is updated to 227 1.12.4_8 or newer. 228 22920140831: 230 The libatf-c and libatf-c++ major versions were downgraded to 0 and 231 1 respectively to match the upstream numbers. They were out of 232 sync because, when they were originally added to FreeBSD, the 233 upstream versions were not respected. These libraries are private 234 and not yet built by default, so renumbering them should be a 235 non-issue. However, unclean source trees will yield broken test 236 programs once the operator executes "make delete-old-libs" after a 237 "make installworld". 238 239 Additionally, the atf-sh binary was made private by moving it into 240 /usr/libexec/. Already-built shell test programs will keep the 241 path to the old binary so they will break after "make delete-old" 242 is run. 243 244 If you are using WITH_TESTS=yes (not the default), wipe the object 245 tree and rebuild from scratch to prevent spurious test failures. 246 This is only needed once: the misnumbered libraries and misplaced 247 binaries have been added to OptionalObsoleteFiles.inc so they will 248 be removed during a clean upgrade. 249 25020140814: 251 The ixgbe tunables now match their sysctl counterparts, for example: 252 hw.ixgbe.enable_aim => hw.ix.enable_aim 253 Anyone using ixgbe tunables should ensure they update /boot/loader.conf. 254 25520140801: 256 The NFSv4.1 server committed by r269398 changes the internal 257 function call interfaces used between the NFS and krpc modules. 258 As such, __FreeBSD_version was bumped. 259 26020140729: 261 The default unbound configuration has been modified to address 262 issues with reverse lookups on networks that use private 263 address ranges. If you use the local_unbound service, run 264 "service local_unbound setup" as root to regenerate your 265 configuration, then "service local_unbound reload" to load the 266 new configuration. 267 26820140717: 269 It is no longer necessary to include the dwarf version in your DEBUG 270 options in your kernel config file. The bug that required it to be 271 placed in the config file has bene fixed. DEBUG should now just 272 contain -g. The build system will automatically update things 273 to do the right thing. 274 27520140715: 276 Several ABI breaking changes were merged to CTL and new iSCSI code. 277 All CTL and iSCSI-related tools, such as ctladm, ctld, iscsid and 278 iscsictl need to be rebuilt to work with a new kernel. 279 28020140708: 281 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 282 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 283 which differs from the behaviour controlled by this knob.) 284 28520140608: 286 On i386 and amd64 systems, the onifconsole flag is now set by default 287 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 288 as a login TTY if it is set in the bootloader as an active kernel 289 console. No changes in behavior should result otherwise. To revert to 290 the previous behavior, set ttyu0 to "off" in /etc/ttys. 291 29220140512: 293 Clang and llvm have been upgraded to 3.4.1 release. 294 29520140321: 296 Clang and llvm have been upgraded to 3.4 release. 297 29820140306: 299 If a Makefile in a tests/ directory was auto-generating a Kyuafile 300 instead of providing an explicit one, this would prevent such 301 Makefile from providing its own Kyuafile in the future during 302 NO_CLEAN builds. This has been fixed in the Makefiles but manual 303 intervention is needed to clean an objdir if you use NO_CLEAN: 304 # find /usr/obj -name Kyuafile | xargs rm -f 305 30620140303: 307 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 308 capability mode support. Please note that enabling the feature in 309 kernel is still highly recommended. 310 31120140227: 312 OpenSSH is now built with sandbox support, and will use sandbox as 313 the default privilege separation method. This requires Capsicum 314 capability mode support in kernel. 315 31620140216: 317 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 318 been deprecated and will not be part of FreeBSD 11.0 and later 319 releases. If you use this driver, please consider switching to 320 the nfe(4) driver instead. 321 32220140120: 323 10.0-RELEASE. 324 32520131216: 326 The behavior of gss_pseudo_random() for the krb5 mechanism 327 has changed, for applications requesting a longer random string 328 than produced by the underlying enctype's pseudo-random() function. 329 In particular, the random string produced from a session key of 330 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 331 be different at the 17th octet and later, after this change. 332 The counter used in the PRF+ construction is now encoded as a 333 big-endian integer in accordance with RFC 4402. 334 __FreeBSD_version is bumped to 1000701. 335 33620131108: 337 The WITHOUT_ATF build knob has been removed and its functionality 338 has been subsumed into the more generic WITHOUT_TESTS. If you were 339 using the former to disable the build of the ATF libraries, you 340 should change your settings to use the latter. 341 34220131031: 343 The default version of mtree is nmtree which is obtained from 344 NetBSD. The output is generally the same, but may vary 345 slightly. If you found you need identical output adding 346 "-F freebsd9" to the command line should do the trick. For the 347 time being, the old mtree is available as fmtree. 348 34920131014: 350 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 351 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 352 1.1.4_8 and verify bsdyml not linked in, before running "make 353 delete-old-libs": 354 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 355 or 356 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 357 35820131010: 359 The rc.d/jail script has been updated to support jail(8) 360 configuration file. The "jail_<jname>_*" rc.conf(5) variables 361 for per-jail configuration are automatically converted to 362 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 363 This is transparently backward compatible. See below about some 364 incompatibilities and rc.conf(5) manual page for more details. 365 366 These variables are now deprecated in favor of jail(8) configuration 367 file. One can use "rc.d/jail config <jname>" command to generate 368 a jail(8) configuration file in /var/run/jail.<jname>.conf without 369 running the jail(8) utility. The default pathname of the 370 configuration file is /etc/jail.conf and can be specified by 371 using $jail_conf or $jail_<jname>_conf variables. 372 373 Please note that jail_devfs_ruleset accepts an integer at 374 this moment. Please consider to rewrite the ruleset name 375 with an integer. 376 37720130930: 378 BIND has been removed from the base system. If all you need 379 is a local resolver, simply enable and start the local_unbound 380 service instead. Otherwise, several versions of BIND are 381 available in the ports tree. The dns/bind99 port is one example. 382 383 With this change, nslookup(1) and dig(1) are no longer in the base 384 system. Users should instead use host(1) and drill(1) which are 385 in the base system. Alternatively, nslookup and dig can 386 be obtained by installing the dns/bind-tools port. 387 38820130916: 389 With the addition of unbound(8), a new unbound user is now 390 required during installworld. "mergemaster -p" can be used to 391 add the user prior to installworld, as documented in the handbook. 392 39320130911: 394 OpenSSH is now built with DNSSEC support, and will by default 395 silently trust signed SSHFP records. This can be controlled with 396 the VerifyHostKeyDNS client configuration setting. DNSSEC support 397 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 398 39920130906: 400 The GNU Compiler Collection and C++ standard library (libstdc++) 401 are no longer built by default on platforms where clang is the system 402 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 403 options in src.conf. 404 40520130905: 406 The PROCDESC kernel option is now part of the GENERIC kernel 407 configuration and is required for the rwhod(8) to work. 408 If you are using custom kernel configuration, you should include 409 'options PROCDESC'. 410 41120130905: 412 The API and ABI related to the Capsicum framework was modified 413 in backward incompatible way. The userland libraries and programs 414 have to be recompiled to work with the new kernel. This includes the 415 following libraries and programs, but the whole buildworld is 416 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 417 kdump, procstat, rwho, rwhod, uniq. 418 41920130903: 420 AES-NI intrinsic support has been added to gcc. The AES-NI module 421 has been updated to use this support. A new gcc is required to build 422 the aesni module on both i386 and amd64. 423 42420130821: 425 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 426 Thus "device padlock_rng" and "device rdrand_rng" should be 427 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 428 42920130813: 430 WITH_ICONV has been split into two feature sets. WITH_ICONV now 431 enables just the iconv* functionality and is now on by default. 432 WITH_LIBICONV_COMPAT enables the libiconv api and link time 433 compatability. Set WITHOUT_ICONV to build the old way. 434 If you have been using WITH_ICONV before, you will very likely 435 need to turn on WITH_LIBICONV_COMPAT. 436 43720130806: 438 INVARIANTS option now enables DEBUG for code with OpenSolaris and 439 Illumos origin, including ZFS. If you have INVARIANTS in your 440 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 441 explicitly. 442 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 443 locks if WITNESS option was set. Because that generated a lot of 444 witness(9) reports and all of them were believed to be false 445 positives, this is no longer done. New option OPENSOLARIS_WITNESS 446 can be used to achieve the previous behavior. 447 44820130806: 449 Timer values in IPv6 data structures now use time_uptime instead 450 of time_second. Although this is not a user-visible functional 451 change, userland utilities which directly use them---ndp(8), 452 rtadvd(8), and rtsold(8) in the base system---need to be updated 453 to r253970 or later. 454 45520130802: 456 find -delete can now delete the pathnames given as arguments, 457 instead of only files found below them or if the pathname did 458 not contain any slashes. Formerly, the following error message 459 would result: 460 461 find: -delete: <path>: relative path potentially not safe 462 463 Deleting the pathnames given as arguments can be prevented 464 without error messages using -mindepth 1 or by changing 465 directory and passing "." as argument to find. This works in the 466 old as well as the new version of find. 467 46820130726: 469 Behavior of devfs rules path matching has been changed. 470 Pattern is now always matched against fully qualified devfs 471 path and slash characters must be explicitly matched by 472 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 473 subdirectories must be reviewed. 474 47520130716: 476 The default ARM ABI has changed to the ARM EABI. The old ABI is 477 incompatible with the ARM EABI and all programs and modules will 478 need to be rebuilt to work with a new kernel. 479 480 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 481 482 NOTE: Support for the old ABI will be removed in the future and 483 users are advised to upgrade. 484 48520130709: 486 pkg_install has been disconnected from the build if you really need it 487 you should add WITH_PKGTOOLS in your src.conf(5). 488 48920130709: 490 Most of network statistics structures were changed to be able 491 keep 64-bits counters. Thus all tools, that work with networking 492 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 493 49420130629: 495 Fix targets that run multiple make's to use && rather than ; 496 so that subsequent steps depend on success of previous. 497 498 NOTE: if building 'universe' with -j* on stable/8 or stable/9 499 it would be better to start the build using bmake, to avoid 500 overloading the machine. 501 50220130618: 503 Fix a bug that allowed a tracing process (e.g. gdb) to write 504 to a memory-mapped file in the traced process's address space 505 even if neither the traced process nor the tracing process had 506 write access to that file. 507 50820130615: 509 CVS has been removed from the base system. An exact copy 510 of the code is available from the devel/cvs port. 511 51220130613: 513 Some people report the following error after the switch to bmake: 514 515 make: illegal option -- J 516 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 517 ... 518 *** [buildworld] Error code 2 519 520 this likely due to an old instance of make in 521 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 522 which src/Makefile will use that blindly, if it exists, so if 523 you see the above error: 524 525 rm -rf `make -V MAKEPATH` 526 527 should resolve it. 528 52920130516: 530 Use bmake by default. 531 Whereas before one could choose to build with bmake via 532 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 533 make. The goal is to remove these knobs for 10-RELEASE. 534 535 It is worth noting that bmake (like gmake) treats the command 536 line as the unit of failure, rather than statements within the 537 command line. Thus '(cd some/where && dosomething)' is safer 538 than 'cd some/where; dosomething'. The '()' allows consistent 539 behavior in parallel build. 540 54120130429: 542 Fix a bug that allows NFS clients to issue READDIR on files. 543 54420130426: 545 The WITHOUT_IDEA option has been removed because 546 the IDEA patent expired. 547 54820130426: 549 The sysctl which controls TRIM support under ZFS has been renamed 550 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 551 enabled by default. 552 55320130425: 554 The mergemaster command now uses the default MAKEOBJDIRPREFIX 555 rather than creating it's own in the temporary directory in 556 order allow access to bootstrapped versions of tools such as 557 install and mtree. When upgrading from version of FreeBSD where 558 the install command does not support -l, you will need to 559 install a new mergemaster command if mergemaster -p is required. 560 This can be accomplished with the command (cd src/usr.sbin/mergemaster 561 && make install). 562 56320130404: 564 Legacy ATA stack, disabled and replaced by new CAM-based one since 565 FreeBSD 9.0, completely removed from the sources. Kernel modules 566 atadisk and atapi*, user-level tools atacontrol and burncd are 567 removed. Kernel option `options ATA_CAM` is now permanently enabled 568 and removed. 569 57020130319: 571 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 572 and socketpair(2). Software, in particular Kerberos, may 573 automatically detect and use these during building. The resulting 574 binaries will not work on older kernels. 575 57620130308: 577 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 578 information, see the respective 20130304 entry). 579 58020130304: 581 Recent commits to callout(9) changed the size of struct callout, 582 so the KBI is probably heavily disturbed. Also, some functions 583 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 584 by macros. Every kernel module using it won't load, so rebuild 585 is requested. 586 587 The ctl device has been re-enabled in GENERIC for i386 and amd64, 588 but does not initialize by default (because of the new CTL_DISABLE 589 option) to save memory. To re-enable it, remove the CTL_DISABLE 590 option from the kernel config file or set kern.cam.ctl.disable=0 591 in /boot/loader.conf. 592 59320130301: 594 The ctl device has been disabled in GENERIC for i386 and amd64. 595 This was done due to the extra memory being allocated at system 596 initialisation time by the ctl driver which was only used if 597 a CAM target device was created. This makes a FreeBSD system 598 unusable on 128MB or less of RAM. 599 60020130208: 601 A new compression method (lz4) has been merged to -HEAD. Please 602 refer to zpool-features(7) for more information. 603 604 Please refer to the "ZFS notes" section of this file for information 605 on upgrading boot ZFS pools. 606 60720130129: 608 A BSD-licensed patch(1) variant has been added and is installed 609 as bsdpatch, being the GNU version the default patch. 610 To inverse the logic and use the BSD-licensed one as default, 611 while having the GNU version installed as gnupatch, rebuild 612 and install world with the WITH_BSD_PATCH knob set. 613 61420130121: 615 Due to the use of the new -l option to install(1) during build 616 and install, you must take care not to directly set the INSTALL 617 make variable in your /etc/make.conf, /etc/src.conf, or on the 618 command line. If you wish to use the -C flag for all installs 619 you may be able to add INSTALL+=-C to /etc/make.conf or 620 /etc/src.conf. 621 62220130118: 623 The install(1) option -M has changed meaning and now takes an 624 argument that is a file or path to append logs to. In the 625 unlikely event that -M was the last option on the command line 626 and the command line contained at least two files and a target 627 directory the first file will have logs appended to it. The -M 628 option served little practical purpose in the last decade so its 629 use is expected to be extremely rare. 630 63120121223: 632 After switching to Clang as the default compiler some users of ZFS 633 on i386 systems started to experience stack overflow kernel panics. 634 Please consider using 'options KSTACK_PAGES=4' in such configurations. 635 63620121222: 637 GEOM_LABEL now mangles label names read from file system metadata. 638 Mangling affect labels containing spaces, non-printable characters, 639 '%' or '"'. Device names in /etc/fstab and other places may need to 640 be updated. 641 64220121217: 643 By default, only the 10 most recent kernel dumps will be saved. To 644 restore the previous behaviour (no limit on the number of kernel dumps 645 stored in the dump directory) add the following line to /etc/rc.conf: 646 647 savecore_flags="" 648 64920121201: 650 With the addition of auditdistd(8), a new auditdistd user is now 651 required during installworld. "mergemaster -p" can be used to 652 add the user prior to installworld, as documented in the handbook. 653 65420121117: 655 The sin6_scope_id member variable in struct sockaddr_in6 is now 656 filled by the kernel before passing the structure to the userland via 657 sysctl or routing socket. This means the KAME-specific embedded scope 658 id in sin6_addr.s6_addr[2] is always cleared in userland application. 659 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 660 __FreeBSD_version is bumped to 1000025. 661 66220121105: 663 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 664 This means that the world and kernel will be compiled with clang 665 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 666 and /usr/bin/cpp. To disable this behavior and revert to building 667 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 668 of current may need to bootstrap WITHOUT_CLANG first if the clang 669 build fails (its compatibility window doesn't extend to the 9 stable 670 branch point). 671 67220121102: 673 The IPFIREWALL_FORWARD kernel option has been removed. Its 674 functionality now turned on by default. 675 67620121023: 677 The ZERO_COPY_SOCKET kernel option has been removed and 678 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 679 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 680 mechanism which is not safe and may result in kernel crashes. 681 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 682 driver supports disposeable external page sized mbuf storage. 683 Proper replacements for both zero-copy mechanisms are under 684 consideration and will eventually lead to complete removal 685 of the two kernel options. 686 68720121023: 688 The IPv4 network stack has been converted to network byte 689 order. The following modules need to be recompiled together 690 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 691 pf(4), ipfw(4), ng_ipfw(4), stf(4). 692 69320121022: 694 Support for non-MPSAFE filesystems was removed from VFS. The 695 VFS_VERSION was bumped, all filesystem modules shall be 696 recompiled. 697 69820121018: 699 All the non-MPSAFE filesystems have been disconnected from 700 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 701 portalfs, smbfs, xfs. 702 70320121016: 704 The interface cloning API and ABI has changed. The following 705 modules need to be recompiled together with kernel: 706 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 707 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 708 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 709 71020121015: 711 The sdhci driver was split in two parts: sdhci (generic SD Host 712 Controller logic) and sdhci_pci (actual hardware driver). 713 No kernel config modifications are required, but if you 714 load sdhc as a module you must switch to sdhci_pci instead. 715 71620121014: 717 Import the FUSE kernel and userland support into base system. 718 71920121013: 720 The GNU sort(1) program has been removed since the BSD-licensed 721 sort(1) has been the default for quite some time and no serious 722 problems have been reported. The corresponding WITH_GNU_SORT 723 knob has also gone. 724 72520121006: 726 The pfil(9) API/ABI for AF_INET family has been changed. Packet 727 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 728 with new kernel. 729 73020121001: 731 The net80211(4) ABI has been changed to allow for improved driver 732 PS-POLL and power-save support. All wireless drivers need to be 733 recompiled to work with the new kernel. 734 73520120913: 736 The random(4) support for the VIA hardware random number 737 generator (`PADLOCK') is no longer enabled unconditionally. 738 Add the padlock_rng device in the custom kernel config if 739 needed. The GENERIC kernels on i386 and amd64 do include the 740 device, so the change only affects the custom kernel 741 configurations. 742 74320120908: 744 The pf(4) packet filter ABI has been changed. pfctl(8) and 745 snmp_pf module need to be recompiled to work with new kernel. 746 74720120828: 748 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 749 to -HEAD. Pools that have empty_bpobj in active state can not be 750 imported read-write with ZFS implementations that do not support 751 this feature. For more information read the zpool-features(5) 752 manual page. 753 75420120727: 755 The sparc64 ZFS loader has been changed to no longer try to auto- 756 detect ZFS providers based on diskN aliases but now requires these 757 to be explicitly listed in the OFW boot-device environment variable. 758 75920120712: 760 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 761 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 762 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 763 76420120712: 765 The following sysctls and tunables have been renamed for consistency 766 with other variables: 767 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 768 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 769 77020120628: 771 The sort utility has been replaced with BSD sort. For now, GNU sort 772 is also available as "gnusort" or the default can be set back to 773 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 774 installed as "bsdsort". 775 77620120611: 777 A new version of ZFS (pool version 5000) has been merged to -HEAD. 778 Starting with this version the old system of ZFS pool versioning 779 is superseded by "feature flags". This concept enables forward 780 compatibility against certain future changes in functionality of ZFS 781 pools. The first read-only compatible "feature flag" for ZFS pools 782 is named "com.delphix:async_destroy". For more information 783 read the new zpool-features(5) manual page. 784 Please refer to the "ZFS notes" section of this file for information 785 on upgrading boot ZFS pools. 786 78720120417: 788 The malloc(3) implementation embedded in libc now uses sources imported 789 as contrib/jemalloc. The most disruptive API change is to 790 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 791 delete it prior to installworld, and optionally re-create it using the 792 new format after rebooting. See malloc.conf(5) for details 793 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 794 NAMESPACE section). 795 79620120328: 797 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 798 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 799 now spelled mips. This is to aid compatibility with third-party 800 software that expects this naming scheme in uname(3). Little-endian 801 settings are unchanged. If you are updating a big-endian mips64 machine 802 from before this change, you may need to set MACHINE_ARCH=mips64 in 803 your environment before the new build system will recognize your machine. 804 80520120306: 806 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 807 platforms. 808 80920120229: 810 Now unix domain sockets behave "as expected" on nullfs(5). Previously 811 nullfs(5) did not pass through all behaviours to the underlying layer, 812 as a result if we bound to a socket on the lower layer we could connect 813 only to the lower path; if we bound to the upper layer we could connect 814 only to the upper path. The new behavior is one can connect to both the 815 lower and the upper paths regardless what layer path one binds to. 816 81720120211: 818 The getifaddrs upgrade path broken with 20111215 has been restored. 819 If you have upgraded in between 20111215 and 20120209 you need to 820 recompile libc again with your kernel. You still need to recompile 821 world to be able to configure CARP but this restriction already 822 comes from 20111215. 823 82420120114: 825 The set_rcvar() function has been removed from /etc/rc.subr. All 826 base and ports rc.d scripts have been updated, so if you have a 827 port installed with a script in /usr/local/etc/rc.d you can either 828 hand-edit the rcvar= line, or reinstall the port. 829 830 An easy way to handle the mass-update of /etc/rc.d: 831 rm /etc/rc.d/* && mergemaster -i 832 83320120109: 834 panic(9) now stops other CPUs in the SMP systems, disables interrupts 835 on the current CPU and prevents other threads from running. 836 This behavior can be reverted using the kern.stop_scheduler_on_panic 837 tunable/sysctl. 838 The new behavior can be incompatible with kern.sync_on_panic. 839 84020111215: 841 The carp(4) facility has been changed significantly. Configuration 842 of the CARP protocol via ifconfig(8) has changed, as well as format 843 of CARP events submitted to devd(8) has changed. See manual pages 844 for more information. The arpbalance feature of carp(4) is currently 845 not supported anymore. 846 847 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 848 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 849 need to be recompiled. 850 85120111122: 852 The acpi_wmi(4) status device /dev/wmistat has been renamed to 853 /dev/wmistat0. 854 85520111108: 856 The option VFS_ALLOW_NONMPSAFE option has been added in order to 857 explicitely support non-MPSAFE filesystems. 858 It is on by default for all supported platform at this present 859 time. 860 86120111101: 862 The broken amd(4) driver has been replaced with esp(4) in the amd64, 863 i386 and pc98 GENERIC kernel configuration files. 864 86520110930: 866 sysinstall has been removed 867 86820110923: 869 The stable/9 branch created in subversion. This corresponds to the 870 RELENG_9 branch in CVS. 871 87220110913: 873 This commit modifies vfs_register() so that it uses a hash 874 calculation to set vfc_typenum, which is enabled by default. 875 The first time a system is booted after this change, the 876 vfc_typenum values will change for all file systems. The 877 main effect of this is a change to the NFS server file handles 878 for file systems that use vfc_typenum in their fsid, such as ZFS. 879 It will, however, prevent vfc_typenum from changing when file 880 systems are loaded in a different order for subsequent reboots. 881 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 882 until you are ready to remount all NFS clients after a reboot. 883 88420110828: 885 Bump the shared library version numbers for libraries that 886 do not use symbol versioning, have changed the ABI compared 887 to stable/8 and which shared library version was not bumped. 888 Done as part of 9.0-RELEASE cycle. 889 89020110815: 891 During the merge of Capsicum features, the fget(9) KPI was modified. 892 This may require the rebuilding of out-of-tree device drivers -- 893 issues have been reported specifically with the nVidia device driver. 894 __FreeBSD_version is bumped to 900041. 895 896 Also, there is a period between 20110811 and 20110814 where the 897 special devices /dev/{stdin,stdout,stderr} did not work correctly. 898 Building world from a kernel during that window may not work. 899 90020110628: 901 The packet filter (pf) code has been updated to OpenBSD 4.5. 902 You need to update userland tools to be in sync with kernel. 903 This update breaks backward compatibility with earlier pfsync(4) 904 versions. Care must be taken when updating redundant firewall setups. 905 90620110608: 907 The following sysctls and tunables are retired on x86 platforms: 908 machdep.hlt_cpus 909 machdep.hlt_logical_cpus 910 The following sysctl is retired: 911 machdep.hyperthreading_allowed 912 The sysctls were supposed to provide a way to dynamically offline and 913 online selected CPUs on x86 platforms, but the implementation has not 914 been reliable especially with SCHED_ULE scheduler. 915 machdep.hyperthreading_allowed tunable is still available to ignore 916 hyperthreading CPUs at OS level. 917 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 918 where X is an APIC ID of a CPU. Be advised, though, that disabling 919 CPUs in non-uniform fashion will result in non-uniform topology and 920 may lead to sub-optimal system performance with SCHED_ULE, which is 921 a default scheduler. 922 92320110607: 924 cpumask_t type is retired and cpuset_t is used in order to describe 925 a mask of CPUs. 926 92720110531: 928 Changes to ifconfig(8) for dynamic address family detection mandate 929 that you are running a kernel of 20110525 or later. Make sure to 930 follow the update procedure to boot a new kernel before installing 931 world. 932 93320110513: 934 Support for sun4v architecture is officially dropped 935 93620110503: 937 Several KPI breaking changes have been committed to the mii(4) layer, 938 the PHY drivers and consequently some Ethernet drivers using mii(4). 939 This means that miibus.ko and the modules of the affected Ethernet 940 drivers need to be recompiled. 941 942 Note to kernel developers: Given that the OUI bit reversion problem 943 was fixed as part of these changes all mii(4) commits related to OUIs, 944 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 945 handling, no longer can be merged verbatim to stable/8 and previous 946 branches. 947 94820110430: 949 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 950 into their kernel configurations along with 'device pci'. 951 95220110427: 953 The default NFS client is now the new NFS client, so fstype "newnfs" 954 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 955 Although mounts via fstype "nfs" will usually work without userland 956 changes, it is recommended that the mount(8) and mount_nfs(8) 957 commands be rebuilt from sources and that a link to mount_nfs called 958 mount_oldnfs be created. The new client is compiled into the 959 kernel with "options NFSCL" and this is needed for diskless root 960 file systems. The GENERIC kernel configs have been changed to use 961 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 962 To use the regular/old client, you can "mount -t oldnfs ...". For 963 a diskless root file system, you must also include a line like: 964 965 vfs.root.mountfrom="oldnfs:" 966 967 in the boot/loader.conf on the root fs on the NFS server to make 968 a diskless root fs use the old client. 969 97020110424: 971 The GENERIC kernels for all architectures now default to the new 972 CAM-based ATA stack. It means that all legacy ATA drivers were 973 removed and replaced by respective CAM drivers. If you are using 974 ATA device names in /etc/fstab or other places, make sure to update 975 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 976 where 'Y's are the sequential numbers starting from zero for each type 977 in order of detection, unless configured otherwise with tunables, 978 see cam(4)). There will be symbolic links created in /dev/ to map 979 old adX devices to the respective adaY. They should provide basic 980 compatibility for file systems mounting in most cases, but they do 981 not support old user-level APIs and do not have respective providers 982 in GEOM. Consider using updated management tools with new device names. 983 984 It is possible to load devices ahci, ata, siis and mvs as modules, 985 but option ATA_CAM should remain in kernel configuration to make ata 986 module work as CAM driver supporting legacy ATA controllers. Device ata 987 still can be used in modular fashion (atacore + ...). Modules atadisk 988 and atapi* are not used and won't affect operation in ATA_CAM mode. 989 Note that to use CAM-based ATA kernel should include CAM devices 990 scbus, pass, da (or explicitly ada), cd and optionally others. All of 991 them are parts of the cam module. 992 993 ataraid(4) functionality is now supported by the RAID GEOM class. 994 To use it you can load geom_raid kernel module and use graid(8) tool 995 for management. Instead of /dev/arX device names, use /dev/raid/rX. 996 997 No kernel config options or code have been removed, so if a problem 998 arises, please report it and optionally revert to the old ATA stack. 999 In order to do it you can remove from the kernel config: 1000 options ATA_CAM 1001 device ahci 1002 device mvs 1003 device siis 1004 , and instead add back: 1005 device atadisk # ATA disk drives 1006 device ataraid # ATA RAID drives 1007 device atapicd # ATAPI CDROM drives 1008 device atapifd # ATAPI floppy drives 1009 device atapist # ATAPI tape drives 1010 101120110423: 1012 The default NFS server has been changed to the new server, which 1013 was referred to as the experimental server. If you need to switch 1014 back to the old NFS server, you must now put the "-o" option on 1015 both the mountd and nfsd commands. This can be done using the 1016 mountd_flags and nfs_server_flags rc.conf variables until an 1017 update to the rc scripts is committed, which is coming soon. 1018 101920110418: 1020 The GNU Objective-C runtime library (libobjc), and other Objective-C 1021 related components have been removed from the base system. If you 1022 require an Objective-C library, please use one of the available ports. 1023 102420110331: 1025 ath(4) has been split into bus- and device- modules. if_ath contains 1026 the HAL, the TX rate control and the network device code. if_ath_pci 1027 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 1028 contains the AHB glue. Users need to load both if_ath_pci and if_ath 1029 in order to use ath on everything else. 1030 1031 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 1032 need to load if_ath and if_ath_pci for ath(4) operation. 1033 103420110314: 1035 As part of the replacement of sysinstall, the process of building 1036 release media has changed significantly. For details, please re-read 1037 release(7), which has been updated to reflect the new build process. 1038 103920110218: 1040 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 1041 is the last available version under GPLv2. It brings a number of new 1042 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 1043 4.1 and SSE 4.2), better support for powerpc64, a number of new 1044 directives, and lots of other small improvements. See the ChangeLog 1045 file in contrib/binutils for the full details. 1046 104720110218: 1048 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 1049 compliant, and will now use half of hash for authentication. 1050 This will break interoperability with all stacks (including all 1051 actual FreeBSD versions) who implement 1052 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 1053 authentication). 1054 The only workaround with such peers is to use another HMAC 1055 algorithm for IPsec ("phase 2") authentication. 1056 105720110207: 1058 Remove the uio_yield prototype and symbol. This function has 1059 been misnamed since it was introduced and should not be 1060 globally exposed with this name. The equivalent functionality 1061 is now available using kern_yield(curthread->td_user_pri). 1062 The function remains undocumented. 1063 106420110112: 1065 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 1066 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 1067 for scalar sysctls is defined but disabled. Code that needs 1068 UQUAD to pass the type checking that must compile on older 1069 systems where the define is not present can check against 1070 __FreeBSD_version >= 900030. 1071 1072 The system dialog(1) has been replaced with a new version previously 1073 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 1074 with the previous version, but the libdialog associated with it has 1075 a largely incompatible API. As such, the original version of libdialog 1076 will be kept temporarily as libodialog, until its base system consumers 1077 are replaced or updated. Bump __FreeBSD_version to 900030. 1078 107920110103: 1080 If you are trying to run make universe on a -stable system, and you get 1081 the following warning: 1082 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 1083 unknown. config(8) likely too old." 1084 or something similar to it, then you must upgrade your -stable system 1085 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 1086 stable/8) or build the config from the latest stable/8 branch and 1087 install it on your system. 1088 1089 Prior to this date, building a current universe on 8-stable system from 1090 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 1091 error in the first kernel build phase. A new config on those old 1092 systems will fix that problem for older versions of -current. 1093 109420101228: 1095 The TCP stack has been modified to allow Khelp modules to interact with 1096 it via helper hook points and store per-connection data in the TCP 1097 control block. Bump __FreeBSD_version to 900029. User space tools that 1098 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 1099 be recompiled. 1100 110120101114: 1102 Generic IEEE 802.3 annex 31B full duplex flow control support has been 1103 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 1104 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 1105 to take advantage of it instead of using custom implementations. This 1106 means that these drivers now no longer unconditionally advertise 1107 support for flow control but only do so if flow control is a selected 1108 media option. This was implemented in the generic support that way in 1109 order to allow flow control to be switched on and off via ifconfig(8) 1110 with the PHY specific default to typically off in order to protect 1111 from unwanted effects. Consequently, if you used flow control with 1112 one of the above mentioned drivers you now need to explicitly enable 1113 it, for example via: 1114 ifconfig bge0 media auto mediaopt flowcontrol 1115 1116 Along with the above mentioned changes generic support for setting 1117 1000baseT master mode also has been added and brgphy(4), ciphy(4), 1118 e1000phy(4) as well as ip1000phy(4) have been converted to take 1119 advantage of it. This means that these drivers now no longer take the 1120 link0 parameter for selecting master mode but the master media option 1121 has to be used instead, for example like in the following: 1122 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 1123 1124 Selection of master mode now is also available with all other PHY 1125 drivers supporting 1000baseT. 1126 112720101111: 1128 The TCP stack has received a significant update to add support for 1129 modularised congestion control and generally improve the clarity of 1130 congestion control decisions. Bump __FreeBSD_version to 900025. User 1131 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 1132 sockstat) need to be recompiled. 1133 113420101002: 1135 The man(1) utility has been replaced by a new version that no longer 1136 uses /etc/manpath.config. Please consult man.conf(5) for how to 1137 migrate local entries to the new format. 1138 113920100928: 1140 The copyright strings printed by login(1) and sshd(8) at the time of a 1141 new connection have been removed to follow other operating systems and 1142 upstream sshd. 1143 114420100915: 1145 A workaround for a fixed ld bug has been removed in kernel code, 1146 so make sure that your system ld is built from sources after 1147 revision 210245 from 2010-07-19 (r211583 if building head kernel 1148 on stable/8, r211584 for stable/7; both from 2010-08-21). 1149 A symptom of incorrect ld version is different addresses for 1150 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 1151 115220100913: 1153 The $ipv6_prefer variable in rc.conf(5) has been split into 1154 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 1155 1156 The $ip6addrctl_policy is a variable to choose a pre-defined 1157 address selection policy set by ip6addrctl(8). A value 1158 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 1159 default is "AUTO". 1160 1161 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 1162 flag (see an entry of 20090926) is set on an interface with no 1163 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 1164 security reason. If you want IPv6 link-local address on all 1165 interfaces by default, set this to "YES". 1166 1167 The old ipv6_prefer="YES" is equivalent to 1168 ipv6_activate_all_interfaces="YES" and 1169 ip6addrctl_policy="ipv6_prefer". 1170 117120100913: 1172 DTrace has grown support for userland tracing. Due to this, DTrace is 1173 now i386 and amd64 only. 1174 dtruss(1) is now installed by default on those systems and a new 1175 kernel module is needed for userland tracing: fasttrap. 1176 No changes to your kernel config file are necessary to enable 1177 userland tracing, but you might consider adding 'STRIP=' and 1178 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 1179 to have informative userland stack traces in DTrace (ustack). 1180 118120100725: 1182 The acpi_aiboost(4) driver has been removed in favor of the new 1183 aibs(4) driver. You should update your kernel configuration file. 1184 118520100722: 1186 BSD grep has been imported to the base system and it is built by 1187 default. It is completely BSD licensed, highly GNU-compatible, uses 1188 less memory than its GNU counterpart and has a small codebase. 1189 However, it is slower than its GNU counterpart, which is mostly 1190 noticeable for larger searches, for smaller ones it is measurable 1191 but not significant. The reason is complex, the most important factor 1192 is that we lack a modern and efficient regex library and GNU 1193 overcomes this by optimizing the searches internally. Future work 1194 on improving the regex performance is planned, for the meantime, 1195 users that need better performance, can build GNU grep instead by 1196 setting the WITH_GNU_GREP knob. 1197 119820100713: 1199 Due to the import of powerpc64 support, all existing powerpc kernel 1200 configuration files must be updated with a machine directive like this: 1201 machine powerpc powerpc 1202 1203 In addition, an updated config(8) is required to build powerpc kernels 1204 after this change. 1205 120620100713: 1207 A new version of ZFS (version 15) has been merged to -HEAD. 1208 This version uses a python library for the following subcommands: 1209 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 1210 For full functionality of these commands the following port must 1211 be installed: sysutils/py-zfs 1212 121320100429: 1214 'vm_page's are now hashed by physical address to an array of mutexes. 1215 Currently this is only used to serialize access to hold_count. Over 1216 time the page queue mutex will be peeled away. This changes the size 1217 of pmap on every architecture. And requires all callers of vm_page_hold 1218 and vm_page_unhold to be updated. 1219 122020100402: 1221 WITH_CTF can now be specified in src.conf (not recommended, there 1222 are some problems with static executables), make.conf (would also 1223 affect ports which do not use GNU make and do not override the 1224 compile targets) or in the kernel config (via "makeoptions 1225 WITH_CTF=yes"). 1226 When WITH_CTF was specified there before this was silently ignored, 1227 so make sure that WITH_CTF is not used in places which could lead 1228 to unwanted behavior. 1229 123020100311: 1231 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 1232 to allow 32-bit compatibility on non-x86 platforms. All kernel 1233 configurations on amd64 and ia64 platforms using these options must 1234 be modified accordingly. 1235 123620100113: 1237 The utmp user accounting database has been replaced with utmpx, 1238 the user accounting interface standardized by POSIX. 1239 Unfortunately the semantics of utmp and utmpx don't match, 1240 making it practically impossible to support both interfaces. 1241 The user accounting database is used by tools like finger(1), 1242 last(1), talk(1), w(1) and ac(8). 1243 1244 All applications in the base system use utmpx. This means only 1245 local binaries (e.g. from the ports tree) may still use these 1246 utmp database files. These applications must be rebuilt to make 1247 use of utmpx. 1248 1249 After the system has been upgraded, it is safe to remove the old 1250 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 1251 assuming their contents is of no importance anymore. Old wtmp 1252 databases can only be used by last(1) and ac(8) after they have 1253 been converted to the new format using wtmpcvt(1). 1254 125520100108: 1256 Introduce the kernel thread "deadlock resolver" (which can be enabled 1257 via the DEADLKRES option, see NOTES for more details) and the 1258 sleepq_type() function for sleepqueues. 1259 126020091202: 1261 The rc.firewall and rc.firewall6 were unified, and 1262 rc.firewall6 and rc.d/ip6fw were removed. 1263 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 1264 variables are obsoleted. Instead, the following new rc 1265 variables are added to rc.d/ipfw: 1266 1267 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 1268 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 1269 firewall_simple_onet_ipv6, firewall_trusted_ipv6 1270 1271 The meanings correspond to the relevant IPv4 variables. 1272 127320091125: 1274 8.0-RELEASE. 1275 127620091113: 1277 The default terminal emulation for syscons(4) has been changed 1278 from cons25 to xterm on all platforms except pc98. This means 1279 that the /etc/ttys file needs to be updated to ensure correct 1280 operation of applications on the console. 1281 1282 The terminal emulation style can be toggled per window by using 1283 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 1284 options can be used to change the compile-time default back to 1285 cons25. 1286 1287 To prevent graphical artifacts, make sure the TERM environment 1288 variable is set to match the terminal emulation that is being 1289 performed by syscons(4). 1290 129120091109: 1292 The layout of the structure ieee80211req_scan_result has changed. 1293 Applications that require wireless scan results (e.g. ifconfig(8)) 1294 from net80211 need to be recompiled. 1295 1296 Applications such as wpa_supplicant(8) may require a full world 1297 build without using NO_CLEAN in order to get synchronized with the 1298 new structure. 1299 130020091025: 1301 The iwn(4) driver has been updated to support the 5000 and 5150 series. 1302 There's one kernel module for each firmware. Adding "device iwnfw" 1303 to the kernel configuration file means including all three firmware 1304 images inside the kernel. If you want to include just the one for 1305 your wireless card, use the devices iwn4965fw, iwn5000fw or 1306 iwn5150fw. 1307 130820090926: 1309 The rc.d/network_ipv6, IPv6 configuration script has been integrated 1310 into rc.d/netif. The changes are the following: 1311 1312 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 1313 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 1314 Note that both variables need the "inet6" keyword at the head. 1315 1316 Do not set $ipv6_network_interfaces manually if you do not 1317 understand what you are doing. It is not needed in most cases. 1318 1319 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 1320 they are obsolete. 1321 1322 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 1323 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 1324 1325 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 1326 all configured interfaces have "inet6 accept_rtadv" in the 1327 $ifconfig_IF_ipv6. These are for backward compatibility. 1328 1329 3. A new variable $ipv6_prefer has been added. If NO, IPv6 1330 functionality of interfaces with no corresponding 1331 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 1332 and the default address selection policy of ip6addrctl(8) 1333 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 1334 Note that if you want to configure IPv6 functionality on the 1335 disabled interfaces after boot, first you need to clear the flag by 1336 using ifconfig(8) like: 1337 1338 ifconfig em0 inet6 -ifdisabled 1339 1340 If YES, the default address selection policy is set as 1341 IPv6-preferred. 1342 1343 The default value of $ipv6_prefer is NO. 1344 1345 4. If your system need to receive Router Advertisement messages, 1346 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 1347 scripts automatically invoke rtsol(8) when the interface becomes 1348 UP. The Router Advertisement messages are used for SLAAC 1349 (State-Less Address AutoConfiguration). 1350 135120090922: 1352 802.11s D3.03 support was committed. This is incompatible with the 1353 previous code, which was based on D3.0. 1354 135520090912: 1356 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 1357 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 1358 control whether accepting Router Advertisement messages or not. 1359 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 1360 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 1361 The ifconfig(8) utility now supports these flags. 1362 136320090910: 1364 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 1365 mount(8) and -a option for df(1) to see them. 1366 136720090825: 1368 The old tunable hw.bus.devctl_disable has been superseded by 1369 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 1370 replaced by hw.bus.devctl_queue=0. The default for this new tunable 1371 is 1000. 1372 137320090813: 1374 Remove the option STOP_NMI. The default action is now to use NMI only 1375 for KDB via the newly introduced function stop_cpus_hard() and 1376 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 1377 137820090803: 1379 The stable/8 branch created in subversion. This corresponds to the 1380 RELENG_8 branch in CVS. 1381 138220090719: 1383 Bump the shared library version numbers for all libraries that do not 1384 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 1385 __FreeBSD_version to 800105. 1386 138720090714: 1388 Due to changes in the implementation of virtual network stack support, 1389 all network-related kernel modules must be recompiled. As this change 1390 breaks the ABI, bump __FreeBSD_version to 800104. 1391 139220090713: 1393 The TOE interface to the TCP syncache has been modified to remove 1394 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 1395 The cxgb driver is the only TOE consumer affected by this change, and 1396 needs to be recompiled along with the kernel. As this change breaks 1397 the ABI, bump __FreeBSD_version to 800103. 1398 139920090712: 1400 Padding has been added to struct tcpcb, sackhint and tcpstat in 1401 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 1402 maintaining the ABI. However, this change breaks the ABI, so bump 1403 __FreeBSD_version to 800102. User space tools that rely on the size of 1404 any of these structs (e.g. sockstat) need to be recompiled. 1405 140620090630: 1407 The NFS_LEGACYRPC option has been removed along with the old kernel 1408 RPC implementation that this option selected. Kernel configurations 1409 may need to be adjusted. 1410 141120090629: 1412 The network interface device nodes at /dev/net/<interface> have been 1413 removed. All ioctl operations can be performed the normal way using 1414 routing sockets. The kqueue functionality can generally be replaced 1415 with routing sockets. 1416 141720090628: 1418 The documentation from the FreeBSD Documentation Project (Handbook, 1419 FAQ, etc.) is now installed via packages by sysinstall(8) and under 1420 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 1421 142220090624: 1423 The ABI of various structures related to the SYSV IPC API have been 1424 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 1425 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 1426 800100. 1427 142820090622: 1429 Layout of struct vnet has changed as routing related variables were 1430 moved to their own Vimage module. Modules need to be recompiled. Bump 1431 __FreeBSD_version to 800099. 1432 143320090619: 1434 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 1435 respectively. As long as no more than 16 groups per process are used, 1436 no changes should be visible. When more than 16 groups are used, old 1437 binaries may fail if they call getgroups() or getgrouplist() with 1438 statically sized storage. Recompiling will work around this, but 1439 applications should be modified to use dynamically allocated storage 1440 for group arrays as POSIX.1-2008 does not cap an implementation's 1441 number of supported groups at NGROUPS_MAX+1 as previous versions did. 1442 1443 NFS and portalfs mounts may also be affected as the list of groups is 1444 truncated to 16. Users of NFS who use more than 16 groups, should 1445 take care that negative group permissions are not used on the exported 1446 file systems as they will not be reliable unless a GSSAPI based 1447 authentication method is used. 1448 144920090616: 1450 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 1451 option compiles in the support for adaptive spinning for lockmgrs 1452 which want to enable it. The lockinit() function now accepts the flag 1453 LK_ADAPTIVE in order to make the lock object subject to adaptive 1454 spinning when both held in write and read mode. 1455 145620090613: 1457 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 1458 changed. User applications that use this ioctl need to be rebuilt. 1459 146020090611: 1461 The layout of struct thread has changed. Kernel and modules need to 1462 be rebuilt. 1463 146420090608: 1465 The layout of structs ifnet, domain, protosw and vnet_net has changed. 1466 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 1467 146820090602: 1469 window(1) has been removed from the base system. It can now be 1470 installed from ports. The port is called misc/window. 1471 147220090601: 1473 The way we are storing and accessing `routing table' entries has 1474 changed. Programs reading the FIB, like netstat, need to be 1475 re-compiled. 1476 147720090601: 1478 A new netisr implementation has been added for FreeBSD 8. Network 1479 file system modules, such as igmp, ipdivert, and others, should be 1480 rebuilt. 1481 Bump __FreeBSD_version to 800096. 1482 148320090530: 1484 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1485 more valid. 1486 148720090530: 1488 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1489 Bump __FreeBSD_version to 800094. 1490 149120090529: 1492 Add mnt_xflag field to 'struct mount'. File system modules need to be 1493 rebuilt. 1494 Bump __FreeBSD_version to 800093. 1495 149620090528: 1497 The compiling option ADAPTIVE_SX has been retired while it has been 1498 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1499 The KPI for sx_init_flags() changes as accepting flags: 1500 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1501 been introduced in order to handle the reversed logic. 1502 Bump __FreeBSD_version to 800092. 1503 150420090527: 1505 Add support for hierarchical jails. Remove global securelevel. 1506 Bump __FreeBSD_version to 800091. 1507 150820090523: 1509 The layout of struct vnet_net has changed, therefore modules 1510 need to be rebuilt. 1511 Bump __FreeBSD_version to 800090. 1512 151320090523: 1514 The newly imported zic(8) produces a new format in the output. Please 1515 run tzsetup(8) to install the newly created data to /etc/localtime. 1516 151720090520: 1518 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1519 hw.usb.* and is now consistent again with previous releases. 1520 152120090520: 1522 802.11 monitor mode support was revised and driver api's were changed. 1523 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1524 of DLT_IEEE802_11. No user-visible data structures were changed but 1525 applications that use DLT_IEEE802_11 may require changes. 1526 Bump __FreeBSD_version to 800088. 1527 152820090430: 1529 The layout of the following structs has changed: sysctl_oid, 1530 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1531 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1532 panics may be experienced. World rebuild is required for 1533 correctly checking networking state from userland. 1534 Bump __FreeBSD_version to 800085. 1535 153620090429: 1537 MLDv2 and Source-Specific Multicast (SSM) have been merged 1538 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1539 The implementation of SSM within FreeBSD's IPv6 stack closely 1540 follows the IPv4 implementation. 1541 1542 For kernel developers: 1543 1544 * The most important changes are that the ip6_output() and 1545 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1546 and this lock has been downgraded to a non-recursive mutex. 1547 1548 * As with the changes to the IPv4 stack to support SSM, filtering 1549 of inbound multicast traffic must now be performed by transport 1550 protocols within the IPv6 stack. This does not apply to TCP and 1551 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1552 1553 * The KPIs used by IPv6 multicast are similar to those used by 1554 the IPv4 stack, with the following differences: 1555 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1556 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1557 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1558 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1559 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1560 for MLDv1 have an additional 'timer' argument which is used to 1561 jitter the initial membership report for the solicited-node 1562 multicast membership on-link. 1563 * This is not strictly needed for MLDv2, which already jitters 1564 its report transmissions. However, the 'timer' argument is 1565 preserved in case MLDv1 is active on the interface. 1566 1567 * The KAME linked-list based IPv6 membership implementation has 1568 been refactored to use a vector similar to that used by the IPv4 1569 stack. 1570 Code which maintains a list of its own multicast memberships 1571 internally, e.g. carp, has been updated to reflect the new 1572 semantics. 1573 1574 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1575 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1576 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1577 implementation constraint which needs to be addressed in HEAD. 1578 1579 For application developers: 1580 1581 * The changes are broadly similar to those made for the IPv4 1582 stack. 1583 1584 * The use of IPv4 and IPv6 multicast socket options on the same 1585 socket, using mapped addresses, HAS NOT been tested or supported. 1586 1587 * There are a number of issues with the implementation of various 1588 IPv6 multicast APIs which need to be resolved in the API surface 1589 before the implementation is fully compatible with KAME userland 1590 use, and these are mostly to do with interface index treatment. 1591 1592 * The literature available discusses the use of either the delta / ASM 1593 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1594 using setsourcefilter(3)/getsourcefilter(3). For more information 1595 please refer to RFC 3768, 'Socket Interface Extensions for 1596 Multicast Source Filters'. 1597 1598 * Applications which use the published RFC 3678 APIs should be fine. 1599 1600 For systems administrators: 1601 1602 * The mtest(8) utility has been refactored to support IPv6, in 1603 addition to IPv4. Interface addresses are no longer accepted 1604 as arguments, their names must be used instead. The utility 1605 will map the interface name to its first IPv4 address as 1606 returned by getifaddrs(3). 1607 1608 * The ifmcstat(8) utility has also been updated to print the MLDv2 1609 endpoint state and source filter lists via sysctl(3). 1610 1611 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1612 loopback of IPv6 multicast datagrams by default; it defaults to 1 1613 to preserve the existing behaviour. Disabling multicast loopback is 1614 recommended for optimal system performance. 1615 1616 * The IPv6 MROUTING code has been changed to examine this sysctl 1617 instead of attempting to perform a group lookup before looping 1618 back forwarded datagrams. 1619 1620 Bump __FreeBSD_version to 800084. 1621 162220090422: 1623 Implement low-level Bluetooth HCI API. 1624 Bump __FreeBSD_version to 800083. 1625 162620090419: 1627 The layout of struct malloc_type, used by modules to register new 1628 memory allocation types, has changed. Most modules will need to 1629 be rebuilt or panics may be experienced. 1630 Bump __FreeBSD_version to 800081. 1631 163220090415: 1633 Anticipate overflowing inp_flags - add inp_flags2. 1634 This changes most offsets in inpcb, so checking v4 connection 1635 state will require a world rebuild. 1636 Bump __FreeBSD_version to 800080. 1637 163820090415: 1639 Add an llentry to struct route and struct route_in6. Modules 1640 embedding a struct route will need to be recompiled. 1641 Bump __FreeBSD_version to 800079. 1642 164320090414: 1644 The size of rt_metrics_lite and by extension rtentry has changed. 1645 Networking administration apps will need to be recompiled. 1646 The route command now supports show as an alias for get, weighting 1647 of routes, sticky and nostick flags to alter the behavior of stateful 1648 load balancing. 1649 Bump __FreeBSD_version to 800078. 1650 165120090408: 1652 Do not use Giant for kbdmux(4) locking. This is wrong and 1653 apparently causing more problems than it solves. This will 1654 re-open the issue where interrupt handlers may race with 1655 kbdmux(4) in polling mode. Typical symptoms include (but 1656 not limited to) duplicated and/or missing characters when 1657 low level console functions (such as gets) are used while 1658 interrupts are enabled (for example geli password prompt, 1659 mountroot prompt etc.). Disabling kbdmux(4) may help. 1660 166120090407: 1662 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1663 kernel modules referencing any of the above need to be recompiled. 1664 Bump __FreeBSD_version to 800075. 1665 166620090320: 1667 GEOM_PART has become the default partition slicer for storage devices, 1668 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1669 introduces some changes: 1670 1671 MSDOS/EBR: the devices created from MSDOS extended partition entries 1672 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1673 to devices with offset-based names. fstabs may need to be modified. 1674 1675 BSD: the "geometry does not match label" warning is harmless in most 1676 cases but it points to problems in file system misalignment with 1677 disk geometry. The "c" partition is now implicit, covers the whole 1678 top-level drive and cannot be (mis)used by users. 1679 1680 General: Kernel dumps are now not allowed to be written to devices 1681 whose partition types indicate they are meant to be used for file 1682 systems (or, in case of MSDOS partitions, as something else than 1683 the "386BSD" type). 1684 1685 Most of these changes date approximately from 200812. 1686 168720090319: 1688 The uscanner(4) driver has been removed from the kernel. This follows 1689 Linux removing theirs in 2.6 and making libusb the default interface 1690 (supported by sane). 1691 169220090319: 1693 The multicast forwarding code has been cleaned up. netstat(1) 1694 only relies on KVM now for printing bandwidth upcall meters. 1695 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1696 ip6_mroute_mod respectively. The config(5) options for statically 1697 compiling this code remain the same, i.e. 'options MROUTING'. 1698 169920090315: 1700 Support for the IFF_NEEDSGIANT network interface flag has been 1701 removed, which means that non-MPSAFE network device drivers are no 1702 longer supported. In particular, if_ar, if_sr, and network device 1703 drivers from the old (legacy) USB stack can no longer be built or 1704 used. 1705 170620090313: 1707 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1708 a bunch of new language catalog files have also been added. 1709 This means that some common libc messages are now localized and 1710 they depend on the LC_MESSAGES environmental variable. 1711 171220090313: 1713 The k8temp(4) driver has been renamed to amdtemp(4) since 1714 support for Family 10 and Family 11 CPU families was added. 1715 171620090309: 1717 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1718 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1719 1720 For kernel developers, the most important changes are that the 1721 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1722 and this lock has been downgraded to a non-recursive mutex. 1723 1724 Transport protocols (UDP, Raw IP) are now responsible for filtering 1725 inbound multicast traffic according to group membership and source 1726 filters. The imo_multicast_filter() KPI exists for this purpose. 1727 Transports which do not use multicast (SCTP, TCP) already reject 1728 multicast by default. Forwarding and receive performance may improve 1729 as a mutex acquisition is no longer needed in the ip_input() 1730 low-level input path. in_addmulti() and in_delmulti() are shimmed 1731 to new KPIs which exist to support SSM in-kernel. 1732 1733 For application developers, it is recommended that loopback of 1734 multicast datagrams be disabled for best performance, as this 1735 will still cause the lock to be taken for each looped-back 1736 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1737 be tuned to 0 to disable loopback by default; it defaults to 1 1738 to preserve the existing behaviour. 1739 1740 For systems administrators, to obtain best performance with 1741 multicast reception and multiple groups, it is always recommended 1742 that a card with a suitably precise hash filter is used. Hash 1743 collisions will still result in the lock being taken within the 1744 transport protocol input path to check group membership. 1745 1746 If deploying FreeBSD in an environment with IGMP snooping switches, 1747 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1748 enabled; this forces 224.0.0.0/24 group membership to be announced 1749 via IGMP. 1750 1751 The size of 'struct igmpstat' has changed; netstat needs to be 1752 recompiled to reflect this. 1753 Bump __FreeBSD_version to 800070. 1754 175520090309: 1756 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1757 updated to use it. This requires a buildworld/installworld in order to 1758 update the library and dependencies (usbconfig, etc). Its advisable to 1759 rebuild all ports which uses libusb. More specific directions are given 1760 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1761 libusb are no longer required and can be removed. 1762 176320090302: 1764 A workaround is committed to allow the creation of System V shared 1765 memory segment of size > 2 GB on the 64-bit architectures. 1766 Due to a limitation of the existing ABI, the shm_segsz member 1767 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1768 wrong for large segments. Note that limits must be explicitly 1769 raised to allow such segments to be created. 1770 177120090301: 1772 The layout of struct ifnet has changed, requiring a rebuild of all 1773 network device driver modules. 1774 177520090227: 1776 The /dev handling for the new USB stack has changed, a 1777 buildworld/installworld is required for libusb20. 1778 177920090223: 1780 The new USB2 stack has now been permanently moved in and all kernel and 1781 module names reverted to their previous values (eg, usb, ehci, ohci, 1782 ums, ...). The old usb stack can be compiled in by prefixing the name 1783 with the letter 'o', the old usb modules have been removed. 1784 Updating entry 20090216 for xorg and 20090215 for libmap may still 1785 apply. 1786 178720090217: 1788 The rc.conf(5) option if_up_delay has been renamed to 1789 defaultroute_delay to better reflect its purpose. If you have 1790 customized this setting in /etc/rc.conf you need to update it to 1791 use the new name. 1792 179320090216: 1794 xorg 7.4 wants to configure its input devices via hald which does not 1795 yet work with USB2. If the keyboard/mouse does not work in xorg then 1796 add 1797 Option "AllowEmptyInput" "off" 1798 to your ServerLayout section. This will cause X to use the configured 1799 kbd and mouse sections from your xorg.conf. 1800 180120090215: 1802 The GENERIC kernels for all architectures now default to the new USB2 1803 stack. No kernel config options or code have been removed so if a 1804 problem arises please report it and optionally revert to the old USB 1805 stack. If you are loading USB kernel modules or have a custom kernel 1806 that includes GENERIC then ensure that usb names are also changed over, 1807 eg uftdi -> usb2_serial_ftdi. 1808 1809 Older programs linked against the ports libusb 0.1 need to be 1810 redirected to the new stack's libusb20. /etc/libmap.conf can 1811 be used for this: 1812 # Map old usb library to new one for usb2 stack 1813 libusb-0.1.so.8 libusb20.so.1 1814 181520090209: 1816 All USB ethernet devices now attach as interfaces under the name ueN 1817 (eg. ue0). This is to provide a predictable name as vendors often 1818 change usb chipsets in a product without notice. 1819 182020090203: 1821 The ichsmb(4) driver has been changed to require SMBus slave 1822 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1823 All of the other SMBus controller drivers require left-justified 1824 slave addresses, so this change makes all the drivers provide the 1825 same interface. 1826 182720090201: 1828 INET6 statistics (struct ip6stat) was updated. 1829 netstat(1) needs to be recompiled. 1830 183120090119: 1832 NTFS has been removed from GENERIC kernel on amd64 to match 1833 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1834 will load ntfs.ko module automatically when NTFS support is 1835 actually needed, unless ntfs.ko is not installed or security 1836 level prohibits loading kernel modules. If either is the case, 1837 "options NTFS" has to be added into kernel config. 1838 183920090115: 1840 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1841 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1842 800061. User space tools that rely on the size of struct tcpcb in 1843 tcp_var.h (e.g. sockstat) need to be recompiled. 1844 184520081225: 1846 ng_tty(4) module updated to match the new TTY subsystem. 1847 Due to API change, user-level applications must be updated. 1848 New API support added to mpd5 CVS and expected to be present 1849 in next mpd5.3 release. 1850 185120081219: 1852 With __FreeBSD_version 800060 the makefs tool is part of 1853 the base system (it was a port). 1854 185520081216: 1856 The afdata and ifnet locks have been changed from mutexes to 1857 rwlocks, network modules will need to be re-compiled. 1858 185920081214: 1860 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1861 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1862 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1863 architecture and 40 bytes on 64-bit architecture. The userland 1864 applications "arp" and "ndp" have been updated accordingly. 1865 The output from "netstat -r" shows only routing entries and 1866 none of the L2 information. 1867 186820081130: 1869 __FreeBSD_version 800057 marks the switchover from the 1870 binary ath hal to source code. Users must add the line: 1871 1872 options AH_SUPPORT_AR5416 1873 1874 to their kernel config files when specifying: 1875 1876 device ath_hal 1877 1878 The ath_hal module no longer exists; the code is now compiled 1879 together with the driver in the ath module. It is now 1880 possible to tailor chip support (i.e. reduce the set of chips 1881 and thereby the code size); consult ath_hal(4) for details. 1882 188320081121: 1884 __FreeBSD_version 800054 adds memory barriers to 1885 <machine/atomic.h>, new interfaces to ifnet to facilitate 1886 multiple hardware transmit queues for cards that support 1887 them, and a lock-less ring-buffer implementation to 1888 enable drivers to more efficiently manage queueing of 1889 packets. 1890 189120081117: 1892 A new version of ZFS (version 13) has been merged to -HEAD. 1893 This version has zpool attribute "listsnapshots" off by 1894 default, which means "zfs list" does not show snapshots, 1895 and is the same as Solaris behavior. 1896 189720081028: 1898 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1899 190020081009: 1901 The uhci, ohci, ehci and slhci USB Host controller drivers have 1902 been put into separate modules. If you load the usb module 1903 separately through loader.conf you will need to load the 1904 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1905 controller add the following to loader.conf: 1906 1907 uhci_load="YES" 1908 ehci_load="YES" 1909 191020081009: 1911 The ABI used by the PMC toolset has changed. Please keep 1912 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1913 sync. 1914 191520081009: 1916 atapci kernel module now includes only generic PCI ATA 1917 driver. AHCI driver moved to ataahci kernel module. 1918 All vendor-specific code moved into separate kernel modules: 1919 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1920 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1921 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1922 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1923 192420080820: 1925 The TTY subsystem of the kernel has been replaced by a new 1926 implementation, which provides better scalability and an 1927 improved driver model. Most common drivers have been migrated to 1928 the new TTY subsystem, while others have not. The following 1929 drivers have not yet been ported to the new TTY layer: 1930 1931 PCI/ISA: 1932 cy, digi, rc, rp, sio 1933 1934 USB: 1935 ubser, ucycom 1936 1937 Line disciplines: 1938 ng_h4, ng_tty, ppp, sl, snp 1939 1940 Adding these drivers to your kernel configuration file shall 1941 cause compilation to fail. 1942 194320080818: 1944 ntpd has been upgraded to 4.2.4p5. 1945 194620080801: 1947 OpenSSH has been upgraded to 5.1p1. 1948 1949 For many years, FreeBSD's version of OpenSSH preferred DSA 1950 over RSA for host and user authentication keys. With this 1951 upgrade, we've switched to the vendor's default of RSA over 1952 DSA. This may cause upgraded clients to warn about unknown 1953 host keys even for previously known hosts. Users should 1954 follow the usual procedure for verifying host keys before 1955 accepting the RSA key. 1956 1957 This can be circumvented by setting the "HostKeyAlgorithms" 1958 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1959 command line. 1960 1961 Please note that the sequence of keys offered for 1962 authentication has been changed as well. You may want to 1963 specify IdentityFile in a different order to revert this 1964 behavior. 1965 196620080713: 1967 The sio(4) driver has been removed from the i386 and amd64 1968 kernel configuration files. This means uart(4) is now the 1969 default serial port driver on those platforms as well. 1970 1971 To prevent collisions with the sio(4) driver, the uart(4) driver 1972 uses different names for its device nodes. This means the 1973 onboard serial port will now most likely be called "ttyu0" 1974 instead of "ttyd0". You may need to reconfigure applications to 1975 use the new device names. 1976 1977 When using the serial port as a boot console, be sure to update 1978 /boot/device.hints and /etc/ttys before booting the new kernel. 1979 If you forget to do so, you can still manually specify the hints 1980 at the loader prompt: 1981 1982 set hint.uart.0.at="isa" 1983 set hint.uart.0.port="0x3F8" 1984 set hint.uart.0.flags="0x10" 1985 set hint.uart.0.irq="4" 1986 boot -s 1987 198820080609: 1989 The gpt(8) utility has been removed. Use gpart(8) to partition 1990 disks instead. 1991 199220080603: 1993 The version that Linuxulator emulates was changed from 2.4.2 1994 to 2.6.16. If you experience any problems with Linux binaries 1995 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1996 if it fixes the problem contact emulation mailing list. 1997 199820080525: 1999 ISDN4BSD (I4B) was removed from the src tree. You may need to 2000 update a your kernel configuration and remove relevant entries. 2001 200220080509: 2003 I have checked in code to support multiple routing tables. 2004 See the man pages setfib(1) and setfib(2). 2005 This is a hopefully backwards compatible version, 2006 but to make use of it you need to compile your kernel 2007 with options ROUTETABLES=2 (or more up to 16). 2008 200920080420: 2010 The 802.11 wireless support was redone to enable multi-bss 2011 operation on devices that are capable. The underlying device 2012 is no longer used directly but instead wlanX devices are 2013 cloned with ifconfig. This requires changes to rc.conf files. 2014 For example, change: 2015 ifconfig_ath0="WPA DHCP" 2016 to 2017 wlans_ath0=wlan0 2018 ifconfig_wlan0="WPA DHCP" 2019 see rc.conf(5) for more details. In addition, mergemaster of 2020 /etc/rc.d is highly recommended. Simultaneous update of userland 2021 and kernel wouldn't hurt either. 2022 2023 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 2024 modules were merged into the base wlan module. All references 2025 to these modules (e.g. in kernel config files) must be removed. 2026 202720080408: 2028 psm(4) has gained write(2) support in native operation level. 2029 Arbitrary commands can be written to /dev/psm%d and status can 2030 be read back from it. Therefore, an application is responsible 2031 for status validation and error recovery. It is a no-op in 2032 other operation levels. 2033 203420080312: 2035 Support for KSE threading has been removed from the kernel. To 2036 run legacy applications linked against KSE libmap.conf may 2037 be used. The following libmap.conf may be used to ensure 2038 compatibility with any prior release: 2039 2040 libpthread.so.1 libthr.so.1 2041 libpthread.so.2 libthr.so.2 2042 libkse.so.3 libthr.so.3 2043 204420080301: 2045 The layout of struct vmspace has changed. This affects libkvm 2046 and any executables that link against libkvm and use the 2047 kvm_getprocs() function. In particular, but not exclusively, 2048 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 2049 The effects are minimal, but it's advisable to upgrade world 2050 nonetheless. 2051 205220080229: 2053 The latest em driver no longer has support in it for the 2054 82575 adapter, this is now moved to the igb driver. The 2055 split was done to make new features that are incompatible 2056 with older hardware easier to do. 2057 205820080220: 2059 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 2060 likewise the kernel option is now GEOM_LINUX_LVM. 2061 206220080211: 2063 The default NFS mount mode has changed from UDP to TCP for 2064 increased reliability. If you rely on (insecurely) NFS 2065 mounting across a firewall you may need to update your 2066 firewall rules. 2067 206820080208: 2069 Belatedly note the addition of m_collapse for compacting 2070 mbuf chains. 2071 207220080126: 2073 The fts(3) structures have been changed to use adequate 2074 integer types for their members and so to be able to cope 2075 with huge file trees. The old fts(3) ABI is preserved 2076 through symbol versioning in libc, so third-party binaries 2077 using fts(3) should still work, although they will not take 2078 advantage of the extended types. At the same time, some 2079 third-party software might fail to build after this change 2080 due to unportable assumptions made in its source code about 2081 fts(3) structure members. Such software should be fixed 2082 by its vendor or, in the worst case, in the ports tree. 2083 FreeBSD_version 800015 marks this change for the unlikely 2084 case that a portable fix is impossible. 2085 208620080123: 2087 To upgrade to -current after this date, you must be running 2088 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 2089 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 2090 209120071128: 2092 The ADAPTIVE_GIANT kernel option has been retired because its 2093 functionality is the default now. 2094 209520071118: 2096 The AT keyboard emulation of sunkbd(4) has been turned on 2097 by default. In order to make the special symbols of the Sun 2098 keyboards driven by sunkbd(4) work under X these now have 2099 to be configured the same way as Sun USB keyboards driven 2100 by ukbd(4) (which also does AT keyboard emulation), f.e.: 2101 2102 Option "XkbLayout" "us" 2103 Option "XkbRules" "xorg" 2104 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 2105 210620071024: 2107 It has been decided that it is desirable to provide ABI 2108 backwards compatibility to the FreeBSD 4/5/6 versions of the 2109 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 2110 broken with the introduction of PCI domain support (see the 2111 20070930 entry). Unfortunately, this required the ABI of 2112 PCIOCGETCONF to be broken again in order to be able to 2113 provide backwards compatibility to the old version of that 2114 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 2115 again. As for prominent ports this affects neither pciutils 2116 nor xorg-server this time, the hal port needs to be rebuilt 2117 however. 2118 211920071020: 2120 The misnamed kthread_create() and friends have been renamed 2121 to kproc_create() etc. Many of the callers already 2122 used kproc_start().. 2123 I will return kthread_create() and friends in a while 2124 with implementations that actually create threads, not procs. 2125 Renaming corresponds with version 800002. 2126 212720071010: 2128 RELENG_7 branched. 2129 2130COMMON ITEMS: 2131 2132 General Notes 2133 ------------- 2134 Avoid using make -j when upgrading. While generally safe, there are 2135 sometimes problems using -j to upgrade. If your upgrade fails with 2136 -j, please try again without -j. From time to time in the past there 2137 have been problems using -j with buildworld and/or installworld. This 2138 is especially true when upgrading between "distant" versions (eg one 2139 that cross a major release boundary or several minor releases, or when 2140 several months have passed on the -current branch). 2141 2142 Sometimes, obscure build problems are the result of environment 2143 poisoning. This can happen because the make utility reads its 2144 environment when searching for values for global variables. To run 2145 your build attempts in an "environmental clean room", prefix all make 2146 commands with 'env -i '. See the env(1) manual page for more details. 2147 2148 When upgrading from one major version to another it is generally best 2149 to upgrade to the latest code in the currently installed branch first, 2150 then do an upgrade to the new branch. This is the best-tested upgrade 2151 path, and has the highest probability of being successful. Please try 2152 this approach before reporting problems with a major version upgrade. 2153 2154 When upgrading a live system, having a root shell around before 2155 installing anything can help undo problems. Not having a root shell 2156 around can lead to problems if pam has changed too much from your 2157 starting point to allow continued authentication after the upgrade. 2158 2159 ZFS notes 2160 --------- 2161 When upgrading the boot ZFS pool to a new version, always follow 2162 these two steps: 2163 2164 1.) recompile and reinstall the ZFS boot loader and boot block 2165 (this is part of "make buildworld" and "make installworld") 2166 2167 2.) update the ZFS boot block on your boot drive 2168 2169 The following example updates the ZFS boot block on the first 2170 partition (freebsd-boot) of a GPT partitioned drive ad0: 2171 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 2172 2173 Non-boot pools do not need these updates. 2174 2175 To build a kernel 2176 ----------------- 2177 If you are updating from a prior version of FreeBSD (even one just 2178 a few days old), you should follow this procedure. It is the most 2179 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2180 2181 make kernel-toolchain 2182 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2183 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2184 2185 To test a kernel once 2186 --------------------- 2187 If you just want to boot a kernel once (because you are not sure 2188 if it works, or if you want to boot a known bad kernel to provide 2189 debugging information) run 2190 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2191 nextboot -k testkernel 2192 2193 To just build a kernel when you know that it won't mess you up 2194 -------------------------------------------------------------- 2195 This assumes you are already running a CURRENT system. Replace 2196 ${arch} with the architecture of your machine (e.g. "i386", 2197 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 2198 2199 cd src/sys/${arch}/conf 2200 config KERNEL_NAME_HERE 2201 cd ../compile/KERNEL_NAME_HERE 2202 make depend 2203 make 2204 make install 2205 2206 If this fails, go to the "To build a kernel" section. 2207 2208 To rebuild everything and install it on the current system. 2209 ----------------------------------------------------------- 2210 # Note: sometimes if you are running current you gotta do more than 2211 # is listed here if you are upgrading from a really old current. 2212 2213 <make sure you have good level 0 dumps> 2214 make buildworld 2215 make kernel KERNCONF=YOUR_KERNEL_HERE 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 To cross-install current onto a separate partition 2225 -------------------------------------------------- 2226 # In this approach we use a separate partition to hold 2227 # current's root, 'usr', and 'var' directories. A partition 2228 # holding "/", "/usr" and "/var" should be about 2GB in 2229 # size. 2230 2231 <make sure you have good level 0 dumps> 2232 <boot into -stable> 2233 make buildworld 2234 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2235 <maybe newfs current's root partition> 2236 <mount current's root partition on directory ${CURRENT_ROOT}> 2237 make installworld DESTDIR=${CURRENT_ROOT} 2238 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2239 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2240 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2241 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2242 <reboot into current> 2243 <do a "native" rebuild/install as described in the previous section> 2244 <maybe install compatibility libraries from ports/misc/compat*> 2245 <reboot> 2246 2247 2248 To upgrade in-place from stable to current 2249 ---------------------------------------------- 2250 <make sure you have good level 0 dumps> 2251 make buildworld [9] 2252 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 2253 [1] 2254 <reboot in single user> [3] 2255 mergemaster -p [5] 2256 make installworld 2257 mergemaster -i [4] 2258 make delete-old [6] 2259 <reboot> 2260 2261 Make sure that you've read the UPDATING file to understand the 2262 tweaks to various things you need. At this point in the life 2263 cycle of current, things change often and you are on your own 2264 to cope. The defaults can also change, so please read ALL of 2265 the UPDATING entries. 2266 2267 Also, if you are tracking -current, you must be subscribed to 2268 freebsd-current@freebsd.org. Make sure that before you update 2269 your sources that you have read and understood all the recent 2270 messages there. If in doubt, please track -stable which has 2271 much fewer pitfalls. 2272 2273 [1] If you have third party modules, such as vmware, you 2274 should disable them at this point so they don't crash your 2275 system on reboot. 2276 2277 [3] From the bootblocks, boot -s, and then do 2278 fsck -p 2279 mount -u / 2280 mount -a 2281 cd src 2282 adjkerntz -i # if CMOS is wall time 2283 Also, when doing a major release upgrade, it is required that 2284 you boot into single user mode to do the installworld. 2285 2286 [4] Note: This step is non-optional. Failure to do this step 2287 can result in a significant reduction in the functionality of the 2288 system. Attempting to do it by hand is not recommended and those 2289 that pursue this avenue should read this file carefully, as well 2290 as the archives of freebsd-current and freebsd-hackers mailing lists 2291 for potential gotchas. The -U option is also useful to consider. 2292 See mergemaster(8) for more information. 2293 2294 [5] Usually this step is a noop. However, from time to time 2295 you may need to do this if you get unknown user in the following 2296 step. It never hurts to do it all the time. You may need to 2297 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2298 install) after the buildworld before this step if you last updated 2299 from current before 20130425 or from -stable before 20130430. 2300 2301 [6] This only deletes old files and directories. Old libraries 2302 can be deleted by "make delete-old-libs", but you have to make 2303 sure that no program is using those libraries anymore. 2304 2305 [8] In order to have a kernel that can run the 4.x binaries needed to 2306 do an installworld, you must include the COMPAT_FREEBSD4 option in 2307 your kernel. Failure to do so may leave you with a system that is 2308 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2309 required to run the 5.x binaries on more recent kernels. And so on 2310 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2311 2312 Make sure that you merge any new devices from GENERIC since the 2313 last time you updated your kernel config file. 2314 2315 [9] When checking out sources, you must include the -P flag to have 2316 cvs prune empty directories. 2317 2318 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2319 "?=" instead of the "=" assignment operator, so that buildworld can 2320 override the CPUTYPE if it needs to. 2321 2322 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2323 not on the command line, or in /etc/make.conf. buildworld will 2324 warn if it is improperly defined. 2325FORMAT: 2326 2327This file contains a list, in reverse chronological order, of major 2328breakages in tracking -current. It is not guaranteed to be a complete 2329list of such breakages, and only contains entries since October 10, 2007. 2330If you need to see UPDATING entries from before that date, you will need 2331to fetch an UPDATING file from an older FreeBSD release. 2332 2333Copyright information: 2334 2335Copyright 1998-2009 M.
