New NTP version is 4.2.8p4. 32 33 The configuration file syntax has been changed, thus mergemaster 34 run is recommended. Now the "kod" parameter requires "limited" 35 parameter. If the ntp.conf is not updated, the ntpd will run 36 successfully, but with KoD disabled. 37 3820151002: p28 FreeBSD-SA-15:24.rpcbind [revised] 39 Revised patch to address a regression that prevents NIS from working. 40 4120150929: p27 FreeBSD-SA-15:24.rpcbind 42 43 Fix rpcbind(8) remote denial of service.

[SA-14:19] 205 20620140909: p1 FreeBSD-SA-14:18.openssl 207 Fix OpenSSL multiple vulnerabilities. [SA-14:18] 208 20920140716: 210 9.3-RELEASE. 211 21220140608: 213 On i386 and amd64 systems, the onifconsole flag is now set by default 214 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled 215 as a login TTY if it is set in the bootloader as an active kernel 216 console. No changes in behavior should result otherwise. To revert to 217 the previous behavior, set ttyu0 to "off" in /etc/ttys. 218 21920140512: 220 Clang and llvm have been upgraded to 3.4.1 release. 221 22220140321: 223 Clang and llvm have been upgraded to 3.4 release. 224 22520140216: 226 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has 227 been deprecated and will not be part of FreeBSD 11.0 and later 228 releases. If you use this driver, please consider switching to 229 the nfe(4) driver instead. 230 23120131216: 232 The behavior of gss_pseudo_random() for the krb5 mechanism 233 has changed, for applications requesting a longer random string 234 than produced by the underlying enctype's pseudo-random() function. 235 In particular, the random string produced from a session key of 236 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 237 be different at the 17th octet and later, after this change. 238 The counter used in the PRF+ construction is now encoded as a 239 big-endian integer in accordance with RFC 4402. 240 __FreeBSD_version is bumped to 902505. 241 24220130930: 243 9.2-RELEASE. 244 24520130823: 246 Behavior of devfs rules path matching has been changed. 247 Pattern is now always matched against fully qualified devfs 248 path and slash characters must be explicitly matched by 249 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 250 subdirectories must be reviewed. 251 25220130705: 253 hastctl(8)'s `status' command output changed to terse one-liner format. 254 Scripts using this should switch to `list' command or be rewritten. 255 25620130618: 257 Fix a bug that allowed a tracing process (e.g. gdb) to write 258 to a memory-mapped file in the traced process's address space 259 even if neither the traced process nor the tracing process had 260 write access to that file. 261 26220130605: 263 Added ZFS TRIM support which is enabled by default. To disable 264 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf. 265 266 Creating new ZFS pools and adding new devices to existing pools 267 first performs a full device level TRIM which can take a significant 268 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0 269 to disable this behaviour. 270 271 ZFS TRIM requires the underlying device support BIO_DELETE which 272 is currently provided by methods such as ATA TRIM and SCSI UNMAP 273 via CAM, which are typically supported by SSD's. 274 275 Stats for ZFS TRIM can be monitored by looking at the sysctl's 276 under kstat.zfs.misc.zio_trim. 277 27820130524: 279 `list' command has been added to hastctl(8). For now, it is full 280 equivalent of `status' command. 281 WARNING: in the near future the output of hastctl's status command 282 will change to more terse format. If you use `hastctl status' 283 for parsing in your scripts, switch to `hastctl list'. 284 28520130430: 286 The mergemaster command now uses the default MAKEOBJDIRPREFIX 287 rather than creating it's own in the temporary directory in 288 order allow access to bootstrapped versions of tools such as 289 install and mtree. When upgrading from version of FreeBSD where 290 the install command does not support -l, you will need to 291 install a new mergemaster command if mergemaster -p is required. 292 This can be accomplished with the command (cd src/usr.sbin/mergemaster 293 && make install). 294 295 Due to the use of the new -l option to install(1) during build 296 and install, you must take care not to directly set the INSTALL 297 make variable in your /etc/make.conf, /etc/src.conf, or on the 298 command line. If you wish to use the -C flag for all installs 299 you may be able to add INSTALL+=-C to /etc/make.conf or 300 /etc/src.conf. 301 30220130429: 303 Fix a bug that allows NFS clients to issue READDIR on files. 304 30520130315: 306 The install(1) option -M has changed meaning and now takes an 307 argument that is a file or path to append logs to. In the 308 unlikely event that -M was the last option on the command line 309 and the command line contained at least two files and a target 310 directory the first file will have logs appended to it. The -M 311 option served little practical purpose in the last decade so it's 312 used expected to be extremely rare. 313 31420130225: 315 A new compression method (lz4) has been merged to. Please refer to 316 zpool-features(7) for more information. 317 318 Please refer to the "ZFS notes" section of this file for information 319 on upgrading boot ZFS pools. 320 32120121224: 322 The VFS KBI was changed with the merge of several nullfs 323 optimizations and fixes. All filesystem modules must be 324 recompiled. 325 32620121218: 327 With the addition of auditdistd(8), a new auditdistd user is now 328 depended on during installworld. "mergemaster -p" can be used to add 329 the user prior to installworld, as documented in the handbook. 330 33120121205: 332 9.1-RELEASE. 333 33420121129: 335 A new version of ZFS (pool version 5000) has been merged to 9-STABLE. 336 Starting with this version the old system of ZFS pool versioning 337 is superseded by "feature flags". This concept enables forward 338 compatibility against certain future changes in functionality of ZFS 339 pools. The first two read-only compatible "feature flags" for ZFS 340 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj". 341 For more information read the new zpool-features(7) manual page. 342 Please refer to the "ZFS notes" section of this file for information 343 on upgrading boot ZFS pools. 344 34520121114: 346 The commit introducing bsd.compiler.mk breaks the traditional 347 building of kernels before this point. Add -m ${SRC}/share/mk 348 (for the right value of SRC) to your command lines to work 349 around; update your useland to a point after this; or use the 350 buildkernel/installkernel top-level targets. See also 20120829. 351 35220121102: 353 The IPFIREWALL_FORWARD kernel option has been removed. Its 354 functionality now turned on by default. 355 35620120913: 357 The random(4) support for the VIA hardware random number 358 generator (`PADLOCK') is no longer enabled unconditionally. 359 Add the PADLOCK_RNG option in the custom kernel config if 360 needed. The GENERIC kernels on i386 and amd64 do include the 361 option, so the change only affects the custom kernel 362 configurations. 363 36420120829: 365 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with 366 the traditional method, you must update your system with an installworld 367 before the kernel will build. The documented make buildkernel/installkernel 368 interfaces (coupled with fresh make kernel-toolchain) continue to work. 369 37020120727: 371 The sparc64 ZFS loader has been changed to no longer try to auto- 372 detect ZFS providers based on diskN aliases but now requires these 373 to be explicitly listed in the OFW boot-device environment variable. 374 37520120422: 376 Now unix domain sockets behave "as expected" on nullfs(5). Previously 377 nullfs(5) did not pass through all behaviours to the underlying layer, 378 as a result if we bound to a socket on the lower layer we could connect 379 only to the lower path; if we bound to the upper layer we could connect 380 only to the upper path. The new behavior is one can connect to both the 381 lower and the upper paths regardless what layer path one binds to. 382 38320120109: 384 The acpi_wmi(4) status device /dev/wmistat has been renamed to 385 /dev/wmistat0. 386 38720120106: 388 A new VOP_ADVISE() was added to support posix_fadvise(2). All 389 filesystem modules must be recompiled. 390 39120120106: 392 The interface of the VOP_VPTOCNP(9) changed, now the returned 393 vnode shall be referenced, previously it was required to be 394 only held. All in-tree filesystems are converted. 395 39620120106: 397 9.0-RELEASE. 398 39920111101: 400 The broken amd(4) driver has been replaced with esp(4) in the amd64, 401 i386 and pc98 GENERIC kernel configuration files. 402 40320110913: 404 This commit modifies vfs_register() so that it uses a hash 405 calculation to set vfc_typenum, which is enabled by default. 406 The first time a system is booted after this change, the 407 vfc_typenum values will change for all file systems. The 408 main effect of this is a change to the NFS server file handles 409 for file systems that use vfc_typenum in their fsid, such as ZFS. 410 It will, however, prevent vfc_typenum from changing when file 411 systems are loaded in a different order for subsequent reboots. 412 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 413 until you are ready to remount all NFS clients after a reboot. 414 41520110828: 416 Bump the shared library version numbers for libraries that 417 do not use symbol versioning, have changed the ABI compared 418 to stable/8 and which shared library version was not bumped. 419 Done as part of 9.0-RELEASE cycle. 420 42120110815: 422 During the merge of Capsicum features, the fget(9) KPI was modified. 423 This may require the rebuilding of out-of-tree device drivers -- 424 issues have been reported specifically with the nVidia device driver. 425 __FreeBSD_version is bumped to 900041. 426 427 Also, there is a period between 20110811 and 20110814 where the 428 special devices /dev/{stdin,stdout,stderr} did not work correctly. 429 Building world from a kernel during that window may not work. 430 43120110628: 432 The packet filter (pf) code has been updated to OpenBSD 4.5. 433 You need to update userland tools to be in sync with kernel. 434 This update breaks backward compatibility with earlier pfsync(4) 435 versions. Care must be taken when updating redundant firewall setups. 436 43720110608: 438 The following sysctls and tunables are retired on x86 platforms: 439 machdep.hlt_cpus 440 machdep.hlt_logical_cpus 441 The following sysctl is retired: 442 machdep.hyperthreading_allowed 443 The sysctls were supposed to provide a way to dynamically offline and 444 online selected CPUs on x86 platforms, but the implementation has not 445 been reliable especially with SCHED_ULE scheduler. 446 machdep.hyperthreading_allowed tunable is still available to ignore 447 hyperthreading CPUs at OS level. 448 Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 449 where X is an APIC ID of a CPU. Be advised, though, that disabling 450 CPUs in non-uniform fashion will result in non-uniform topology and 451 may lead to sub-optimal system performance with SCHED_ULE, which is 452 a default scheduler. 453 45420110607: 455 cpumask_t type is retired and cpuset_t is used in order to describe 456 a mask of CPUs. 457 45820110531: 459 Changes to ifconfig(8) for dynamic address family detection mandate 460 that you are running a kernel of 20110525 or later. Make sure to 461 follow the update procedure to boot a new kernel before installing 462 world. 463 46420110513: 465 Support for sun4v architecture is officially dropped 466 46720110503: 468 Several KPI breaking changes have been committed to the mii(4) layer, 469 the PHY drivers and consequently some Ethernet drivers using mii(4). 470 This means that miibus.ko and the modules of the affected Ethernet 471 drivers need to be recompiled. 472 473 Note to kernel developers: Given that the OUI bit reversion problem 474 was fixed as part of these changes all mii(4) commits related to OUIs, 475 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific 476 handling, no longer can be merged verbatim to stable/8 and previous 477 branches. 478 47920110430: 480 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci' 481 into their kernel configurations along with 'device pci'. 482 48320110427: 484 The default NFS client is now the new NFS client, so fstype "newnfs" 485 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 486 Although mounts via fstype "nfs" will usually work without userland 487 changes, it is recommended that the mount(8) and mount_nfs(8) 488 commands be rebuilt from sources and that a link to mount_nfs called 489 mount_oldnfs be created. The new client is compiled into the 490 kernel with "options NFSCL" and this is needed for diskless root 491 file systems. The GENERIC kernel configs have been changed to use 492 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 493 To use the regular/old client, you can "mount -t oldnfs ...". For 494 a diskless root file system, you must also include a line like: 495 496 vfs.root.mountfrom="oldnfs:" 497 498 in the boot/loader.conf on the root fs on the NFS server to make 499 a diskless root fs use the old client. 500 50120110424: 502 The GENERIC kernels for all architectures now default to the new 503 CAM-based ATA stack. It means that all legacy ATA drivers were 504 removed and replaced by respective CAM drivers. If you are using 505 ATA device names in /etc/fstab or other places, make sure to update 506 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 507 where 'Y's are the sequential numbers starting from zero for each type 508 in order of detection, unless configured otherwise with tunables, 509 see cam(4)). There will be symbolic links created in /dev/ to map 510 old adX devices to the respective adaY. They should provide basic 511 compatibility for file systems mounting in most cases, but they do 512 not support old user-level APIs and do not have respective providers 513 in GEOM. Consider using updated management tools with new device names. 514 515 It is possible to load devices ahci, ata, siis and mvs as modules, 516 but option ATA_CAM should remain in kernel configuration to make ata 517 module work as CAM driver supporting legacy ATA controllers. Device ata 518 still can be used in modular fashion (atacore + ...). Modules atadisk 519 and atapi* are not used and won't affect operation in ATA_CAM mode. 520 Note that to use CAM-based ATA kernel should include CAM devices 521 scbus, pass, da (or explicitly ada), cd and optionally others. All of 522 them are parts of the cam module. 523 524 ataraid(4) functionality is now supported by the RAID GEOM class. 525 To use it you can load geom_raid kernel module and use graid(8) tool 526 for management. Instead of /dev/arX device names, use /dev/raid/rX. 527 528 No kernel config options or code have been removed, so if a problem 529 arises, please report it and optionally revert to the old ATA stack. 530 In order to do it you can remove from the kernel config: 531 options ATA_CAM 532 device ahci 533 device mvs 534 device siis 535 , and instead add back: 536 device atadisk # ATA disk drives 537 device ataraid # ATA RAID drives 538 device atapicd # ATAPI CDROM drives 539 device atapifd # ATAPI floppy drives 540 device atapist # ATAPI tape drives 541 54220110423: 543 The default NFS server has been changed to the new server, which 544 was referred to as the experimental server. If you need to switch 545 back to the old NFS server, you must now put the "-o" option on 546 both the mountd and nfsd commands. This can be done using the 547 mountd_flags and nfs_server_flags rc.conf variables until an 548 update to the rc scripts is committed, which is coming soon. 549 55020110418: 551 The GNU Objective-C runtime library (libobjc), and other Objective-C 552 related components have been removed from the base system. If you 553 require an Objective-C library, please use one of the available ports. 554 55520110331: 556 ath(4) has been split into bus- and device- modules. if_ath contains 557 the HAL, the TX rate control and the network device code. if_ath_pci 558 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb 559 contains the AHB glue. Users need to load both if_ath_pci and if_ath 560 in order to use ath on everything else. 561 562 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only 563 need to load if_ath and if_ath_pci for ath(4) operation. 564 56520110314: 566 As part of the replacement of sysinstall, the process of building 567 release media has changed significantly. For details, please re-read 568 release(7), which has been updated to reflect the new build process. 569 57020110218: 571 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This 572 is the last available version under GPLv2. It brings a number of new 573 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE 574 4.1 and SSE 4.2), better support for powerpc64, a number of new 575 directives, and lots of other small improvements. See the ChangeLog 576 file in contrib/binutils for the full details. 577 57820110218: 579 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868 580 compliant, and will now use half of hash for authentication. 581 This will break interoperability with all stacks (including all 582 actual FreeBSD versions) who implement 583 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for 584 authentication). 585 The only workaround with such peers is to use another HMAC 586 algorithm for IPsec ("phase 2") authentication. 587 58820110207: 589 Remove the uio_yield prototype and symbol. This function has 590 been misnamed since it was introduced and should not be 591 globally exposed with this name. The equivalent functionality 592 is now available using kern_yield(curthread->td_user_pri). 593 The function remains undocumented. 594 59520110112: 596 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 597 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 598 for scalar sysctls is defined but disabled. Code that needs 599 UQUAD to pass the type checking that must compile on older 600 systems where the define is not present can check against 601 __FreeBSD_version >= 900030. 602 603 The system dialog(1) has been replaced with a new version previously 604 in ports as devel/cdialog. dialog(1) is mostly command-line compatible 605 with the previous version, but the libdialog associated with it has 606 a largely incompatible API. As such, the original version of libdialog 607 will be kept temporarily as libodialog, until its base system consumers 608 are replaced or updated. Bump __FreeBSD_version to 900030. 609 61020110103: 611 If you are trying to run make universe on a -stable system, and you get 612 the following warning: 613 "Makefile", line 356: "Target architecture for i386/conf/GENERIC 614 unknown. config(8) likely too old." 615 or something similar to it, then you must upgrade your -stable system 616 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 617 stable/8) or build the config from the latest stable/8 branch and 618 install it on your system. 619 620 Prior to this date, building a current universe on 8-stable system from 621 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 622 error in the first kernel build phase. A new config on those old 623 systems will fix that problem for older versions of -current. 624 62520101228: 626 The TCP stack has been modified to allow Khelp modules to interact with 627 it via helper hook points and store per-connection data in the TCP 628 control block. Bump __FreeBSD_version to 900029. User space tools that 629 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 630 be recompiled. 631 63220101114: 633 Generic IEEE 802.3 annex 31B full duplex flow control support has been 634 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 635 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 636 to take advantage of it instead of using custom implementations. This 637 means that these drivers now no longer unconditionally advertise 638 support for flow control but only do so if flow control is a selected 639 media option. This was implemented in the generic support that way in 640 order to allow flow control to be switched on and off via ifconfig(8) 641 with the PHY specific default to typically off in order to protect 642 from unwanted effects. Consequently, if you used flow control with 643 one of the above mentioned drivers you now need to explicitly enable 644 it, for example via: 645 ifconfig bge0 media auto mediaopt flowcontrol 646 647 Along with the above mentioned changes generic support for setting 648 1000baseT master mode also has been added and brgphy(4), ciphy(4), 649 e1000phy(4) as well as ip1000phy(4) have been converted to take 650 advantage of it. This means that these drivers now no longer take the 651 link0 parameter for selecting master mode but the master media option 652 has to be used instead, for example like in the following: 653 ifconfig bge0 media 1000baseT mediaopt full-duplex,master 654 655 Selection of master mode now is also available with all other PHY 656 drivers supporting 1000baseT. 657 65820101111: 659 The TCP stack has received a significant update to add support for 660 modularised congestion control and generally improve the clarity of 661 congestion control decisions. Bump __FreeBSD_version to 900025. User 662 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 663 sockstat) need to be recompiled. 664 66520101002: 666 The man(1) utility has been replaced by a new version that no longer 667 uses /etc/manpath.config. Please consult man.conf(5) for how to 668 migrate local entries to the new format. 669 67020100928: 671 The copyright strings printed by login(1) and sshd(8) at the time of a 672 new connection have been removed to follow other operating systems and 673 upstream sshd. 674 67520100915: 676 A workaround for a fixed ld bug has been removed in kernel code, 677 so make sure that your system ld is built from sources after 678 revision 210245 from 2010-07-19 (r211583 if building head kernel 679 on stable/8, r211584 for stable/7; both from 2010-08-21). 680 A symptom of incorrect ld version is different addresses for 681 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules. 682 68320100913: 684 The $ipv6_prefer variable in rc.conf(5) has been split into 685 $ip6addrctl_policy and $ipv6_activate_all_interfaces. 686 687 The $ip6addrctl_policy is a variable to choose a pre-defined 688 address selection policy set by ip6addrctl(8). A value 689 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 690 default is "AUTO". 691 692 The $ipv6_activate_all_interfaces specifies whether IFDISABLED 693 flag (see an entry of 20090926) is set on an interface with no 694 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 695 security reason. If you want IPv6 link-local address on all 696 interfaces by default, set this to "YES". 697 698 The old ipv6_prefer="YES" is equivalent to 699 ipv6_activate_all_interfaces="YES" and 700 ip6addrctl_policy="ipv6_prefer". 701 70220100913: 703 DTrace has grown support for userland tracing. Due to this, DTrace is 704 now i386 and amd64 only. 705 dtruss(1) is now installed by default on those systems and a new 706 kernel module is needed for userland tracing: fasttrap. 707 No changes to your kernel config file are necessary to enable 708 userland tracing, but you might consider adding 'STRIP=' and 709 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 710 to have informative userland stack traces in DTrace (ustack). 711 71220100725: 713 The acpi_aiboost(4) driver has been removed in favor of the new 714 aibs(4) driver. You should update your kernel configuration file. 715 71620100722: 717 BSD grep has been imported to the base system and it is built by 718 default. It is completely BSD licensed, highly GNU-compatible, uses 719 less memory than its GNU counterpart and has a small codebase. 720 However, it is slower than its GNU counterpart, which is mostly 721 noticeable for larger searches, for smaller ones it is measurable 722 but not significant. The reason is complex, the most important factor 723 is that we lack a modern and efficient regex library and GNU 724 overcomes this by optimizing the searches internally. Future work 725 on improving the regex performance is planned, for the meantime, 726 users that need better performance, can build GNU grep instead by 727 setting the WITH_GNU_GREP knob. 728 72920100713: 730 Due to the import of powerpc64 support, all existing powerpc kernel 731 configuration files must be updated with a machine directive like this: 732 machine powerpc powerpc 733 734 In addition, an updated config(8) is required to build powerpc kernels 735 after this change. 736 73720100713: 738 A new version of ZFS (version 15) has been merged to -HEAD. 739 This version uses a python library for the following subcommands: 740 zfs allow, zfs unallow, zfs groupspace, zfs userspace. 741 For full functionality of these commands the following port must 742 be installed: sysutils/py-zfs 743 74420100429: 745 'vm_page's are now hashed by physical address to an array of mutexes. 746 Currently this is only used to serialize access to hold_count. Over 747 time the page queue mutex will be peeled away. This changes the size 748 of pmap on every architecture. And requires all callers of vm_page_hold 749 and vm_page_unhold to be updated. 750 75120100402: 752 WITH_CTF can now be specified in src.conf (not recommended, there 753 are some problems with static executables), make.conf (would also 754 affect ports which do not use GNU make and do not override the 755 compile targets) or in the kernel config (via "makeoptions 756 WITH_CTF=yes"). 757 When WITH_CTF was specified there before this was silently ignored, 758 so make sure that WITH_CTF is not used in places which could lead 759 to unwanted behavior. 760 76120100311: 762 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32 763 to allow 32-bit compatibility on non-x86 platforms. All kernel 764 configurations on amd64 and ia64 platforms using these options must 765 be modified accordingly. 766 76720100113: 768 The utmp user accounting database has been replaced with utmpx, 769 the user accounting interface standardized by POSIX. 770 Unfortunately the semantics of utmp and utmpx don't match, 771 making it practically impossible to support both interfaces. 772 The user accounting database is used by tools like finger(1), 773 last(1), talk(1), w(1) and ac(8). 774 775 All applications in the base system use utmpx. This means only 776 local binaries (e.g. from the ports tree) may still use these 777 utmp database files. These applications must be rebuilt to make 778 use of utmpx. 779 780 After the system has been upgraded, it is safe to remove the old 781 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*), 782 assuming their contents is of no importance anymore. Old wtmp 783 databases can only be used by last(1) and ac(8) after they have 784 been converted to the new format using wtmpcvt(1). 785 78620100108: 787 Introduce the kernel thread "deadlock resolver" (which can be enabled 788 via the DEADLKRES option, see NOTES for more details) and the 789 sleepq_type() function for sleepqueues. 790 79120091202: 792 The rc.firewall and rc.firewall6 were unified, and 793 rc.firewall6 and rc.d/ip6fw were removed. 794 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc 795 variables are obsoleted. Instead, the following new rc 796 variables are added to rc.d/ipfw: 797 798 firewall_client_net_ipv6, firewall_simple_iif_ipv6, 799 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6, 800 firewall_simple_onet_ipv6, firewall_trusted_ipv6 801 802 The meanings correspond to the relevant IPv4 variables. 803 80420091125: 805 8.0-RELEASE. 806 80720091113: 808 The default terminal emulation for syscons(4) has been changed 809 from cons25 to xterm on all platforms except pc98. This means 810 that the /etc/ttys file needs to be updated to ensure correct 811 operation of applications on the console. 812 813 The terminal emulation style can be toggled per window by using 814 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration 815 options can be used to change the compile-time default back to 816 cons25. 817 818 To prevent graphical artifacts, make sure the TERM environment 819 variable is set to match the terminal emulation that is being 820 performed by syscons(4). 821 82220091109: 823 The layout of the structure ieee80211req_scan_result has changed. 824 Applications that require wireless scan results (e.g. ifconfig(8)) 825 from net80211 need to be recompiled. 826 827 Applications such as wpa_supplicant(8) may require a full world 828 build without using NO_CLEAN in order to get synchronized with the 829 new structure. 830 83120091025: 832 The iwn(4) driver has been updated to support the 5000 and 5150 series. 833 There's one kernel module for each firmware. Adding "device iwnfw" 834 to the kernel configuration file means including all three firmware 835 images inside the kernel. If you want to include just the one for 836 your wireless card, use the devices iwn4965fw, iwn5000fw or 837 iwn5150fw. 838 83920090926: 840 The rc.d/network_ipv6, IPv6 configuration script has been integrated 841 into rc.d/netif. The changes are the following: 842 843 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 844 for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 845 Note that both variables need the "inet6" keyword at the head. 846 847 Do not set $ipv6_network_interfaces manually if you do not 848 understand what you are doing. It is not needed in most cases. 849 850 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 851 they are obsolete. 852 853 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 854 "inet6 accept_rtadv" keyword in ifconfig(8) instead. 855 856 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 857 all configured interfaces have "inet6 accept_rtadv" in the 858 $ifconfig_IF_ipv6. These are for backward compatibility. 859 860 3. A new variable $ipv6_prefer has been added. If NO, IPv6 861 functionality of interfaces with no corresponding 862 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 863 and the default address selection policy of ip6addrctl(8) 864 is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 865 Note that if you want to configure IPv6 functionality on the 866 disabled interfaces after boot, first you need to clear the flag by 867 using ifconfig(8) like: 868 869 ifconfig em0 inet6 -ifdisabled 870 871 If YES, the default address selection policy is set as 872 IPv6-preferred. 873 874 The default value of $ipv6_prefer is NO. 875 876 4. If your system need to receive Router Advertisement messages, 877 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 878 scripts automatically invoke rtsol(8) when the interface becomes 879 UP. The Router Advertisement messages are used for SLAAC 880 (State-Less Address AutoConfiguration). 881 88220090922: 883 802.11s D3.03 support was committed. This is incompatible with the 884 previous code, which was based on D3.0. 885 88620090912: 887 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value 888 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to 889 control whether accepting Router Advertisement messages or not. 890 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and 891 a sysctl variable net.inet6.ip6.auto_linklocal is its default value. 892 The ifconfig(8) utility now supports these flags. 893 89420090910: 895 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for 896 mount(8) and -a option for df(1) to see them. 897 89820090825: 899 The old tunable hw.bus.devctl_disable has been superseded by 900 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be 901 replaced by hw.bus.devctl_queue=0. The default for this new tunable 902 is 1000. 903 90420090813: 905 Remove the option STOP_NMI. The default action is now to use NMI only 906 for KDB via the newly introduced function stop_cpus_hard() and 907 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64. 908 90920090803: 910 The stable/8 branch created in subversion. This corresponds to the 911 RELENG_8 branch in CVS. 912 91320090719: 914 Bump the shared library version numbers for all libraries that do not 915 use symbol versioning as part of the 8.0-RELEASE cycle. Bump 916 __FreeBSD_version to 800105. 917 91820090714: 919 Due to changes in the implementation of virtual network stack support, 920 all network-related kernel modules must be recompiled. As this change 921 breaks the ABI, bump __FreeBSD_version to 800104. 922 92320090713: 924 The TOE interface to the TCP syncache has been modified to remove 925 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack. 926 The cxgb driver is the only TOE consumer affected by this change, and 927 needs to be recompiled along with the kernel. As this change breaks 928 the ABI, bump __FreeBSD_version to 800103. 929 93020090712: 931 Padding has been added to struct tcpcb, sackhint and tcpstat in 932 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst 933 maintaining the ABI. However, this change breaks the ABI, so bump 934 __FreeBSD_version to 800102. User space tools that rely on the size of 935 any of these structs (e.g. sockstat) need to be recompiled. 936 93720090630: 938 The NFS_LEGACYRPC option has been removed along with the old kernel 939 RPC implementation that this option selected. Kernel configurations 940 may need to be adjusted. 941 94220090629: 943 The network interface device nodes at /dev/net/<interface> have been 944 removed. All ioctl operations can be performed the normal way using 945 routing sockets. The kqueue functionality can generally be replaced 946 with routing sockets. 947 94820090628: 949 The documentation from the FreeBSD Documentation Project (Handbook, 950 FAQ, etc.) is now installed via packages by sysinstall(8) and under 951 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc. 952 95320090624: 954 The ABI of various structures related to the SYSV IPC API have been 955 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel 956 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to 957 800100. 958 95920090622: 960 Layout of struct vnet has changed as routing related variables were 961 moved to their own Vimage module. Modules need to be recompiled. Bump 962 __FreeBSD_version to 800099. 963 96420090619: 965 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 966 respectively. As long as no more than 16 groups per process are used, 967 no changes should be visible. When more than 16 groups are used, old 968 binaries may fail if they call getgroups() or getgrouplist() with 969 statically sized storage. Recompiling will work around this, but 970 applications should be modified to use dynamically allocated storage 971 for group arrays as POSIX.1-2008 does not cap an implementation's 972 number of supported groups at NGROUPS_MAX+1 as previous versions did. 973 974 NFS and portalfs mounts may also be affected as the list of groups is 975 truncated to 16. Users of NFS who use more than 16 groups, should 976 take care that negative group permissions are not used on the exported 977 file systems as they will not be reliable unless a GSSAPI based 978 authentication method is used. 979 98020090616: 981 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This 982 option compiles in the support for adaptive spinning for lockmgrs 983 which want to enable it. The lockinit() function now accepts the flag 984 LK_ADAPTIVE in order to make the lock object subject to adaptive 985 spinning when both held in write and read mode. 986 98720090613: 988 The layout of the structure returned by IEEE80211_IOC_STA_INFO has 989 changed. User applications that use this ioctl need to be rebuilt. 990 99120090611: 992 The layout of struct thread has changed. Kernel and modules need to 993 be rebuilt. 994 99520090608: 996 The layout of structs ifnet, domain, protosw and vnet_net has changed. 997 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097. 998 99920090602: 1000 window(1) has been removed from the base system. It can now be 1001 installed from ports. The port is called misc/window. 1002 100320090601: 1004 The way we are storing and accessing `routing table' entries has 1005 changed. Programs reading the FIB, like netstat, need to be 1006 re-compiled. 1007 100820090601: 1009 A new netisr implementation has been added for FreeBSD 8. Network 1010 file system modules, such as igmp, ipdivert, and others, should be 1011 rebuilt. 1012 Bump __FreeBSD_version to 800096. 1013 101420090530: 1015 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no 1016 more valid. 1017 101820090530: 1019 Add VOP_ACCESSX(9). File system modules need to be rebuilt. 1020 Bump __FreeBSD_version to 800094. 1021 102220090529: 1023 Add mnt_xflag field to 'struct mount'. File system modules need to be 1024 rebuilt. 1025 Bump __FreeBSD_version to 800093. 1026 102720090528: 1028 The compiling option ADAPTIVE_SX has been retired while it has been 1029 introduced the option NO_ADAPTIVE_SX which handles the reversed logic. 1030 The KPI for sx_init_flags() changes as accepting flags: 1031 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has 1032 been introduced in order to handle the reversed logic. 1033 Bump __FreeBSD_version to 800092. 1034 103520090527: 1036 Add support for hierarchical jails. Remove global securelevel. 1037 Bump __FreeBSD_version to 800091. 1038 103920090523: 1040 The layout of struct vnet_net has changed, therefore modules 1041 need to be rebuilt. 1042 Bump __FreeBSD_version to 800090. 1043 104420090523: 1045 The newly imported zic(8) produces a new format in the output. Please 1046 run tzsetup(8) to install the newly created data to /etc/localtime. 1047 104820090520: 1049 The sysctl tree for the usb stack has renamed from hw.usb2.* to 1050 hw.usb.* and is now consistent again with previous releases. 1051 105220090520: 1053 802.11 monitor mode support was revised and driver api's were changed. 1054 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead 1055 of DLT_IEEE802_11. No user-visible data structures were changed but 1056 applications that use DLT_IEEE802_11 may require changes. 1057 Bump __FreeBSD_version to 800088. 1058 105920090430: 1060 The layout of the following structs has changed: sysctl_oid, 1061 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 1062 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 1063 panics may be experienced. World rebuild is required for 1064 correctly checking networking state from userland. 1065 Bump __FreeBSD_version to 800085. 1066 106720090429: 1068 MLDv2 and Source-Specific Multicast (SSM) have been merged 1069 to the IPv6 stack. VIMAGE hooks are in but not yet used. 1070 The implementation of SSM within FreeBSD's IPv6 stack closely 1071 follows the IPv4 implementation. 1072 1073 For kernel developers: 1074 1075 * The most important changes are that the ip6_output() and 1076 ip6_input() paths no longer take the IN6_MULTI_LOCK, 1077 and this lock has been downgraded to a non-recursive mutex. 1078 1079 * As with the changes to the IPv4 stack to support SSM, filtering 1080 of inbound multicast traffic must now be performed by transport 1081 protocols within the IPv6 stack. This does not apply to TCP and 1082 SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 1083 1084 * The KPIs used by IPv6 multicast are similar to those used by 1085 the IPv4 stack, with the following differences: 1086 * im6o_mc_filter() is analogous to imo_multicast_filter(). 1087 * The legacy KAME entry points in6_joingroup and in6_leavegroup() 1088 are shimmed to in6_mc_join() and in6_mc_leave() respectively. 1089 * IN6_LOOKUP_MULTI() has been deprecated and removed. 1090 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 1091 for MLDv1 have an additional 'timer' argument which is used to 1092 jitter the initial membership report for the solicited-node 1093 multicast membership on-link. 1094 * This is not strictly needed for MLDv2, which already jitters 1095 its report transmissions. However, the 'timer' argument is 1096 preserved in case MLDv1 is active on the interface. 1097 1098 * The KAME linked-list based IPv6 membership implementation has 1099 been refactored to use a vector similar to that used by the IPv4 1100 stack. 1101 Code which maintains a list of its own multicast memberships 1102 internally, e.g. carp, has been updated to reflect the new 1103 semantics. 1104 1105 * There is a known Lock Order Reversal (LOR) due to in6_setscope() 1106 acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 1107 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 1108 implementation constraint which needs to be addressed in HEAD. 1109 1110 For application developers: 1111 1112 * The changes are broadly similar to those made for the IPv4 1113 stack. 1114 1115 * The use of IPv4 and IPv6 multicast socket options on the same 1116 socket, using mapped addresses, HAS NOT been tested or supported. 1117 1118 * There are a number of issues with the implementation of various 1119 IPv6 multicast APIs which need to be resolved in the API surface 1120 before the implementation is fully compatible with KAME userland 1121 use, and these are mostly to do with interface index treatment. 1122 1123 * The literature available discusses the use of either the delta / ASM 1124 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 1125 using setsourcefilter(3)/getsourcefilter(3). For more information 1126 please refer to RFC 3768, 'Socket Interface Extensions for 1127 Multicast Source Filters'. 1128 1129 * Applications which use the published RFC 3678 APIs should be fine. 1130 1131 For systems administrators: 1132 1133 * The mtest(8) utility has been refactored to support IPv6, in 1134 addition to IPv4. Interface addresses are no longer accepted 1135 as arguments, their names must be used instead. The utility 1136 will map the interface name to its first IPv4 address as 1137 returned by getifaddrs(3). 1138 1139 * The ifmcstat(8) utility has also been updated to print the MLDv2 1140 endpoint state and source filter lists via sysctl(3). 1141 1142 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 1143 loopback of IPv6 multicast datagrams by default; it defaults to 1 1144 to preserve the existing behaviour. Disabling multicast loopback is 1145 recommended for optimal system performance. 1146 1147 * The IPv6 MROUTING code has been changed to examine this sysctl 1148 instead of attempting to perform a group lookup before looping 1149 back forwarded datagrams. 1150 1151 Bump __FreeBSD_version to 800084. 1152 115320090422: 1154 Implement low-level Bluetooth HCI API. 1155 Bump __FreeBSD_version to 800083. 1156 115720090419: 1158 The layout of struct malloc_type, used by modules to register new 1159 memory allocation types, has changed. Most modules will need to 1160 be rebuilt or panics may be experienced. 1161 Bump __FreeBSD_version to 800081. 1162 116320090415: 1164 Anticipate overflowing inp_flags - add inp_flags2. 1165 This changes most offsets in inpcb, so checking v4 connection 1166 state will require a world rebuild. 1167 Bump __FreeBSD_version to 800080. 1168 116920090415: 1170 Add an llentry to struct route and struct route_in6. Modules 1171 embedding a struct route will need to be recompiled. 1172 Bump __FreeBSD_version to 800079. 1173 117420090414: 1175 The size of rt_metrics_lite and by extension rtentry has changed. 1176 Networking administration apps will need to be recompiled. 1177 The route command now supports show as an alias for get, weighting 1178 of routes, sticky and nostick flags to alter the behavior of stateful 1179 load balancing. 1180 Bump __FreeBSD_version to 800078. 1181 118220090408: 1183 Do not use Giant for kbdmux(4) locking. This is wrong and 1184 apparently causing more problems than it solves. This will 1185 re-open the issue where interrupt handlers may race with 1186 kbdmux(4) in polling mode. Typical symptoms include (but 1187 not limited to) duplicated and/or missing characters when 1188 low level console functions (such as gets) are used while 1189 interrupts are enabled (for example geli password prompt, 1190 mountroot prompt etc.). Disabling kbdmux(4) may help. 1191 119220090407: 1193 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 1194 kernel modules referencing any of the above need to be recompiled. 1195 Bump __FreeBSD_version to 800075. 1196 119720090320: 1198 GEOM_PART has become the default partition slicer for storage devices, 1199 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 1200 introduces some changes: 1201 1202 MSDOS/EBR: the devices created from MSDOS extended partition entries 1203 (EBR) can be named differently than with GEOM_MBR and are now symlinks 1204 to devices with offset-based names. fstabs may need to be modified. 1205 1206 BSD: the "geometry does not match label" warning is harmless in most 1207 cases but it points to problems in file system misalignment with 1208 disk geometry. The "c" partition is now implicit, covers the whole 1209 top-level drive and cannot be (mis)used by users. 1210 1211 General: Kernel dumps are now not allowed to be written to devices 1212 whose partition types indicate they are meant to be used for file 1213 systems (or, in case of MSDOS partitions, as something else than 1214 the "386BSD" type). 1215 1216 Most of these changes date approximately from 200812. 1217 121820090319: 1219 The uscanner(4) driver has been removed from the kernel. This follows 1220 Linux removing theirs in 2.6 and making libusb the default interface 1221 (supported by sane). 1222 122320090319: 1224 The multicast forwarding code has been cleaned up. netstat(1) 1225 only relies on KVM now for printing bandwidth upcall meters. 1226 The IPv4 and IPv6 modules are split into ip_mroute_mod and 1227 ip6_mroute_mod respectively. The config(5) options for statically 1228 compiling this code remain the same, i.e. 'options MROUTING'. 1229 123020090315: 1231 Support for the IFF_NEEDSGIANT network interface flag has been 1232 removed, which means that non-MPSAFE network device drivers are no 1233 longer supported. In particular, if_ar, if_sr, and network device 1234 drivers from the old (legacy) USB stack can no longer be built or 1235 used. 1236 123720090313: 1238 POSIX.1 Native Language Support (NLS) has been enabled in libc and 1239 a bunch of new language catalog files have also been added. 1240 This means that some common libc messages are now localized and 1241 they depend on the LC_MESSAGES environmental variable. 1242 124320090313: 1244 The k8temp(4) driver has been renamed to amdtemp(4) since 1245 support for Family 10 and Family 11 CPU families was added. 1246 124720090309: 1248 IGMPv3 and Source-Specific Multicast (SSM) have been merged 1249 to the IPv4 stack. VIMAGE hooks are in but not yet used. 1250 1251 For kernel developers, the most important changes are that the 1252 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 1253 and this lock has been downgraded to a non-recursive mutex. 1254 1255 Transport protocols (UDP, Raw IP) are now responsible for filtering 1256 inbound multicast traffic according to group membership and source 1257 filters. The imo_multicast_filter() KPI exists for this purpose. 1258 Transports which do not use multicast (SCTP, TCP) already reject 1259 multicast by default. Forwarding and receive performance may improve 1260 as a mutex acquisition is no longer needed in the ip_input() 1261 low-level input path. in_addmulti() and in_delmulti() are shimmed 1262 to new KPIs which exist to support SSM in-kernel. 1263 1264 For application developers, it is recommended that loopback of 1265 multicast datagrams be disabled for best performance, as this 1266 will still cause the lock to be taken for each looped-back 1267 datagram transmission. The net.inet.ip.mcast.loop sysctl may 1268 be tuned to 0 to disable loopback by default; it defaults to 1 1269 to preserve the existing behaviour. 1270 1271 For systems administrators, to obtain best performance with 1272 multicast reception and multiple groups, it is always recommended 1273 that a card with a suitably precise hash filter is used. Hash 1274 collisions will still result in the lock being taken within the 1275 transport protocol input path to check group membership. 1276 1277 If deploying FreeBSD in an environment with IGMP snooping switches, 1278 it is recommended that the net.inet.igmp.sendlocal sysctl remain 1279 enabled; this forces 224.0.0.0/24 group membership to be announced 1280 via IGMP. 1281 1282 The size of 'struct igmpstat' has changed; netstat needs to be 1283 recompiled to reflect this. 1284 Bump __FreeBSD_version to 800070. 1285 128620090309: 1287 libusb20.so.1 is now installed as libusb.so.1 and the ports system 1288 updated to use it. This requires a buildworld/installworld in order to 1289 update the library and dependencies (usbconfig, etc). Its advisable to 1290 rebuild all ports which uses libusb. More specific directions are given 1291 in the ports collection UPDATING file. Any /etc/libmap.conf entries for 1292 libusb are no longer required and can be removed. 1293 129420090302: 1295 A workaround is committed to allow the creation of System V shared 1296 memory segment of size > 2 GB on the 64-bit architectures. 1297 Due to a limitation of the existing ABI, the shm_segsz member 1298 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is 1299 wrong for large segments. Note that limits must be explicitly 1300 raised to allow such segments to be created. 1301 130220090301: 1303 The layout of struct ifnet has changed, requiring a rebuild of all 1304 network device driver modules. 1305 130620090227: 1307 The /dev handling for the new USB stack has changed, a 1308 buildworld/installworld is required for libusb20. 1309 131020090223: 1311 The new USB2 stack has now been permanently moved in and all kernel and 1312 module names reverted to their previous values (eg, usb, ehci, ohci, 1313 ums, ...). The old usb stack can be compiled in by prefixing the name 1314 with the letter 'o', the old usb modules have been removed. 1315 Updating entry 20090216 for xorg and 20090215 for libmap may still 1316 apply. 1317 131820090217: 1319 The rc.conf(5) option if_up_delay has been renamed to 1320 defaultroute_delay to better reflect its purpose. If you have 1321 customized this setting in /etc/rc.conf you need to update it to 1322 use the new name. 1323 132420090216: 1325 xorg 7.4 wants to configure its input devices via hald which does not 1326 yet work with USB2. If the keyboard/mouse does not work in xorg then 1327 add 1328 Option "AllowEmptyInput" "off" 1329 to your ServerLayout section. This will cause X to use the configured 1330 kbd and mouse sections from your xorg.conf. 1331 133220090215: 1333 The GENERIC kernels for all architectures now default to the new USB2 1334 stack. No kernel config options or code have been removed so if a 1335 problem arises please report it and optionally revert to the old USB 1336 stack. If you are loading USB kernel modules or have a custom kernel 1337 that includes GENERIC then ensure that usb names are also changed over, 1338 eg uftdi -> usb2_serial_ftdi. 1339 1340 Older programs linked against the ports libusb 0.1 need to be 1341 redirected to the new stack's libusb20. /etc/libmap.conf can 1342 be used for this: 1343 # Map old usb library to new one for usb2 stack 1344 libusb-0.1.so.8 libusb20.so.1 1345 134620090209: 1347 All USB ethernet devices now attach as interfaces under the name ueN 1348 (eg. ue0). This is to provide a predictable name as vendors often 1349 change usb chipsets in a product without notice. 1350 135120090203: 1352 The ichsmb(4) driver has been changed to require SMBus slave 1353 addresses be left-justified (xxxxxxx0b) rather than right-justified. 1354 All of the other SMBus controller drivers require left-justified 1355 slave addresses, so this change makes all the drivers provide the 1356 same interface. 1357 135820090201: 1359 INET6 statistics (struct ip6stat) was updated. 1360 netstat(1) needs to be recompiled. 1361 136220090119: 1363 NTFS has been removed from GENERIC kernel on amd64 to match 1364 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 1365 will load ntfs.ko module automatically when NTFS support is 1366 actually needed, unless ntfs.ko is not installed or security 1367 level prohibits loading kernel modules. If either is the case, 1368 "options NTFS" has to be added into kernel config. 1369 137020090115: 1371 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 1372 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 1373 800061. User space tools that rely on the size of struct tcpcb in 1374 tcp_var.h (e.g. sockstat) need to be recompiled. 1375 137620081225: 1377 ng_tty(4) module updated to match the new TTY subsystem. 1378 Due to API change, user-level applications must be updated. 1379 New API support added to mpd5 CVS and expected to be present 1380 in next mpd5.3 release. 1381 138220081219: 1383 With __FreeBSD_version 800060 the makefs tool is part of 1384 the base system (it was a port). 1385 138620081216: 1387 The afdata and ifnet locks have been changed from mutexes to 1388 rwlocks, network modules will need to be re-compiled. 1389 139020081214: 1391 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 1392 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 1393 The new code reduced struct rtentry{} by 16 bytes on 32-bit 1394 architecture and 40 bytes on 64-bit architecture. The userland 1395 applications "arp" and "ndp" have been updated accordingly. 1396 The output from "netstat -r" shows only routing entries and 1397 none of the L2 information. 1398 139920081130: 1400 __FreeBSD_version 800057 marks the switchover from the 1401 binary ath hal to source code. Users must add the line: 1402 1403 options AH_SUPPORT_AR5416 1404 1405 to their kernel config files when specifying: 1406 1407 device ath_hal 1408 1409 The ath_hal module no longer exists; the code is now compiled 1410 together with the driver in the ath module. It is now 1411 possible to tailor chip support (i.e. reduce the set of chips 1412 and thereby the code size); consult ath_hal(4) for details. 1413 141420081121: 1415 __FreeBSD_version 800054 adds memory barriers to 1416 <machine/atomic.h>, new interfaces to ifnet to facilitate 1417 multiple hardware transmit queues for cards that support 1418 them, and a lock-less ring-buffer implementation to 1419 enable drivers to more efficiently manage queueing of 1420 packets. 1421 142220081117: 1423 A new version of ZFS (version 13) has been merged to -HEAD. 1424 This version has zpool attribute "listsnapshots" off by 1425 default, which means "zfs list" does not show snapshots, 1426 and is the same as Solaris behavior. 1427 142820081028: 1429 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 1430 143120081009: 1432 The uhci, ohci, ehci and slhci USB Host controller drivers have 1433 been put into separate modules. If you load the usb module 1434 separately through loader.conf you will need to load the 1435 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 1436 controller add the following to loader.conf: 1437 1438 uhci_load="YES" 1439 ehci_load="YES" 1440 144120081009: 1442 The ABI used by the PMC toolset has changed. Please keep 1443 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 1444 sync. 1445 144620081009: 1447 atapci kernel module now includes only generic PCI ATA 1448 driver. AHCI driver moved to ataahci kernel module. 1449 All vendor-specific code moved into separate kernel modules: 1450 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, 1451 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, 1452 atamarvell, atamicron, atanational, atanetcell, atanvidia, 1453 atapromise, ataserverworks, atasiliconimage, atasis, atavia 1454 145520080820: 1456 The TTY subsystem of the kernel has been replaced by a new 1457 implementation, which provides better scalability and an 1458 improved driver model. Most common drivers have been migrated to 1459 the new TTY subsystem, while others have not. The following 1460 drivers have not yet been ported to the new TTY layer: 1461 1462 PCI/ISA: 1463 cy, digi, rc, rp, sio 1464 1465 USB: 1466 ubser, ucycom 1467 1468 Line disciplines: 1469 ng_h4, ng_tty, ppp, sl, snp 1470 1471 Adding these drivers to your kernel configuration file shall 1472 cause compilation to fail. 1473 147420080818: 1475 ntpd has been upgraded to 4.2.4p5. 1476 147720080801: 1478 OpenSSH has been upgraded to 5.1p1. 1479 1480 For many years, FreeBSD's version of OpenSSH preferred DSA 1481 over RSA for host and user authentication keys. With this 1482 upgrade, we've switched to the vendor's default of RSA over 1483 DSA. This may cause upgraded clients to warn about unknown 1484 host keys even for previously known hosts. Users should 1485 follow the usual procedure for verifying host keys before 1486 accepting the RSA key. 1487 1488 This can be circumvented by setting the "HostKeyAlgorithms" 1489 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1490 command line. 1491 1492 Please note that the sequence of keys offered for 1493 authentication has been changed as well. You may want to 1494 specify IdentityFile in a different order to revert this 1495 behavior. 1496 149720080713: 1498 The sio(4) driver has been removed from the i386 and amd64 1499 kernel configuration files. This means uart(4) is now the 1500 default serial port driver on those platforms as well. 1501 1502 To prevent collisions with the sio(4) driver, the uart(4) driver 1503 uses different names for its device nodes. This means the 1504 onboard serial port will now most likely be called "ttyu0" 1505 instead of "ttyd0". You may need to reconfigure applications to 1506 use the new device names. 1507 1508 When using the serial port as a boot console, be sure to update 1509 /boot/device.hints and /etc/ttys before booting the new kernel. 1510 If you forget to do so, you can still manually specify the hints 1511 at the loader prompt: 1512 1513 set hint.uart.0.at="isa" 1514 set hint.uart.0.port="0x3F8" 1515 set hint.uart.0.flags="0x10" 1516 set hint.uart.0.irq="4" 1517 boot -s 1518 151920080609: 1520 The gpt(8) utility has been removed. Use gpart(8) to partition 1521 disks instead. 1522 152320080603: 1524 The version that Linuxulator emulates was changed from 2.4.2 1525 to 2.6.16. If you experience any problems with Linux binaries 1526 please try to set sysctl compat.linux.osrelease to 2.4.2 and 1527 if it fixes the problem contact emulation mailing list. 1528 152920080525: 1530 ISDN4BSD (I4B) was removed from the src tree. You may need to 1531 update a your kernel configuration and remove relevant entries. 1532 153320080509: 1534 I have checked in code to support multiple routing tables. 1535 See the man pages setfib(1) and setfib(2). 1536 This is a hopefully backwards compatible version, 1537 but to make use of it you need to compile your kernel 1538 with options ROUTETABLES=2 (or more up to 16). 1539 154020080420: 1541 The 802.11 wireless support was redone to enable multi-bss 1542 operation on devices that are capable. The underlying device 1543 is no longer used directly but instead wlanX devices are 1544 cloned with ifconfig. This requires changes to rc.conf files. 1545 For example, change: 1546 ifconfig_ath0="WPA DHCP" 1547 to 1548 wlans_ath0=wlan0 1549 ifconfig_wlan0="WPA DHCP" 1550 see rc.conf(5) for more details. In addition, mergemaster of 1551 /etc/rc.d is highly recommended. Simultaneous update of userland 1552 and kernel wouldn't hurt either. 1553 1554 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1555 modules were merged into the base wlan module. All references 1556 to these modules (e.g. in kernel config files) must be removed. 1557 155820080408: 1559 psm(4) has gained write(2) support in native operation level. 1560 Arbitrary commands can be written to /dev/psm%d and status can 1561 be read back from it. Therefore, an application is responsible 1562 for status validation and error recovery. It is a no-op in 1563 other operation levels. 1564 156520080312: 1566 Support for KSE threading has been removed from the kernel. To 1567 run legacy applications linked against KSE libmap.conf may 1568 be used. The following libmap.conf may be used to ensure 1569 compatibility with any prior release: 1570 1571 libpthread.so.1 libthr.so.1 1572 libpthread.so.2 libthr.so.2 1573 libkse.so.3 libthr.so.3 1574 157520080301: 1576 The layout of struct vmspace has changed. This affects libkvm 1577 and any executables that link against libkvm and use the 1578 kvm_getprocs() function. In particular, but not exclusively, 1579 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 1580 The effects are minimal, but it's advisable to upgrade world 1581 nonetheless. 1582 158320080229: 1584 The latest em driver no longer has support in it for the 1585 82575 adapter, this is now moved to the igb driver. The 1586 split was done to make new features that are incompatible 1587 with older hardware easier to do. 1588 158920080220: 1590 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 1591 likewise the kernel option is now GEOM_LINUX_LVM. 1592 159320080211: 1594 The default NFS mount mode has changed from UDP to TCP for 1595 increased reliability. If you rely on (insecurely) NFS 1596 mounting across a firewall you may need to update your 1597 firewall rules. 1598 159920080208: 1600 Belatedly note the addition of m_collapse for compacting 1601 mbuf chains. 1602 160320080126: 1604 The fts(3) structures have been changed to use adequate 1605 integer types for their members and so to be able to cope 1606 with huge file trees. The old fts(3) ABI is preserved 1607 through symbol versioning in libc, so third-party binaries 1608 using fts(3) should still work, although they will not take 1609 advantage of the extended types. At the same time, some 1610 third-party software might fail to build after this change 1611 due to unportable assumptions made in its source code about 1612 fts(3) structure members. Such software should be fixed 1613 by its vendor or, in the worst case, in the ports tree. 1614 FreeBSD_version 800015 marks this change for the unlikely 1615 case that a portable fix is impossible. 1616 161720080123: 1618 To upgrade to -current after this date, you must be running 1619 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 1620 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 1621 162220071128: 1623 The ADAPTIVE_GIANT kernel option has been retired because its 1624 functionality is the default now. 1625 162620071118: 1627 The AT keyboard emulation of sunkbd(4) has been turned on 1628 by default. In order to make the special symbols of the Sun 1629 keyboards driven by sunkbd(4) work under X these now have 1630 to be configured the same way as Sun USB keyboards driven 1631 by ukbd(4) (which also does AT keyboard emulation), f.e.: 1632 1633 Option "XkbLayout" "us" 1634 Option "XkbRules" "xorg" 1635 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1636 163720071024: 1638 It has been decided that it is desirable to provide ABI 1639 backwards compatibility to the FreeBSD 4/5/6 versions of the 1640 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 1641 broken with the introduction of PCI domain support (see the 1642 20070930 entry). Unfortunately, this required the ABI of 1643 PCIOCGETCONF to be broken again in order to be able to 1644 provide backwards compatibility to the old version of that 1645 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 1646 again. As for prominent ports this affects neither pciutils 1647 nor xorg-server this time, the hal port needs to be rebuilt 1648 however. 1649 165020071020: 1651 The misnamed kthread_create() and friends have been renamed 1652 to kproc_create() etc. Many of the callers already 1653 used kproc_start().. 1654 I will return kthread_create() and friends in a while 1655 with implementations that actually create threads, not procs. 1656 Renaming corresponds with version 800002. 1657 165820071010: 1659 RELENG_7 branched. 1660 1661COMMON ITEMS: 1662 1663 General Notes 1664 ------------- 1665 Avoid using make -j when upgrading. While generally safe, there are 1666 sometimes problems using -j to upgrade. If your upgrade fails with 1667 -j, please try again without -j. From time to time in the past there 1668 have been problems using -j with buildworld and/or installworld. This 1669 is especially true when upgrading between "distant" versions (eg one 1670 that cross a major release boundary or several minor releases, or when 1671 several months have passed on the -current branch). 1672 1673 Sometimes, obscure build problems are the result of environment 1674 poisoning. This can happen because the make utility reads its 1675 environment when searching for values for global variables. To run 1676 your build attempts in an "environmental clean room", prefix all make 1677 commands with 'env -i '. See the env(1) manual page for more details. 1678 1679 When upgrading from one major version to another it is generally best 1680 to upgrade to the latest code in the currently installed branch first, 1681 then do an upgrade to the new branch. This is the best-tested upgrade 1682 path, and has the highest probability of being successful. Please try 1683 this approach before reporting problems with a major version upgrade. 1684 1685 ZFS notes 1686 --------- 1687 When upgrading the boot ZFS pool to a new version, always follow 1688 these two steps: 1689 1690 1.) recompile and reinstall the ZFS boot loader and boot block 1691 (this is part of "make buildworld" and "make installworld") 1692 1693 2.) update the ZFS boot block on your boot drive 1694 1695 The following example updates the ZFS boot block on the first 1696 partition (freebsd-boot) of a GPT partitioned drive ad0: 1697 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 1698 1699 Non-boot pools do not need these updates. 1700 1701 To build a kernel 1702 ----------------- 1703 If you are updating from a prior version of FreeBSD (even one just 1704 a few days old), you should follow this procedure. It is the most 1705 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1706 1707 make kernel-toolchain 1708 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1709 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1710 1711 To test a kernel once 1712 --------------------- 1713 If you just want to boot a kernel once (because you are not sure 1714 if it works, or if you want to boot a known bad kernel to provide 1715 debugging information) run 1716 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1717 nextboot -k testkernel 1718 1719 To just build a kernel when you know that it won't mess you up 1720 -------------------------------------------------------------- 1721 This assumes you are already running a CURRENT system. Replace 1722 ${arch} with the architecture of your machine (e.g. "i386", 1723 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1724 1725 cd src/sys/${arch}/conf 1726 config KERNEL_NAME_HERE 1727 cd ../compile/KERNEL_NAME_HERE 1728 make depend 1729 make 1730 make install 1731 1732 If this fails, go to the "To build a kernel" section. 1733 1734 To rebuild everything and install it on the current system. 1735 ----------------------------------------------------------- 1736 # Note: sometimes if you are running current you gotta do more than 1737 # is listed here if you are upgrading from a really old current. 1738 1739 <make sure you have good level 0 dumps> 1740 make buildworld 1741 make kernel KERNCONF=YOUR_KERNEL_HERE 1742 [1] 1743 <reboot in single user> [3] 1744 mergemaster -p [5] 1745 make installworld 1746 mergemaster -i [4] 1747 make delete-old [6] 1748 <reboot> 1749 1750 1751 To cross-install current onto a separate partition 1752 -------------------------------------------------- 1753 # In this approach we use a separate partition to hold 1754 # current's root, 'usr', and 'var' directories. A partition 1755 # holding "/", "/usr" and "/var" should be about 2GB in 1756 # size. 1757 1758 <make sure you have good level 0 dumps> 1759 <boot into -stable> 1760 make buildworld 1761 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1762 <maybe newfs current's root partition> 1763 <mount current's root partition on directory ${CURRENT_ROOT}> 1764 make installworld DESTDIR=${CURRENT_ROOT} 1765 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1766 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1767 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1768 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1769 <reboot into current> 1770 <do a "native" rebuild/install as described in the previous section> 1771 <maybe install compatibility libraries from ports/misc/compat*> 1772 <reboot> 1773 1774 1775 To upgrade in-place from stable to current 1776 ---------------------------------------------- 1777 <make sure you have good level 0 dumps> 1778 make buildworld [9] 1779 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1780 [1] 1781 <reboot in single user> [3] 1782 mergemaster -p [5] 1783 make installworld 1784 mergemaster -i [4] 1785 make delete-old [6] 1786 <reboot> 1787 1788 Make sure that you've read the UPDATING file to understand the 1789 tweaks to various things you need. At this point in the life 1790 cycle of current, things change often and you are on your own 1791 to cope. The defaults can also change, so please read ALL of 1792 the UPDATING entries. 1793 1794 Also, if you are tracking -current, you must be subscribed to 1795 freebsd-current@freebsd.org. Make sure that before you update 1796 your sources that you have read and understood all the recent 1797 messages there. If in doubt, please track -stable which has 1798 much fewer pitfalls. 1799 1800 [1] If you have third party modules, such as vmware, you 1801 should disable them at this point so they don't crash your 1802 system on reboot. 1803 1804 [3] From the bootblocks, boot -s, and then do 1805 fsck -p 1806 mount -u / 1807 mount -a 1808 cd src 1809 adjkerntz -i # if CMOS is wall time 1810 Also, when doing a major release upgrade, it is required that 1811 you boot into single user mode to do the installworld. 1812 1813 [4] Note: This step is non-optional. Failure to do this step 1814 can result in a significant reduction in the functionality of the 1815 system. Attempting to do it by hand is not recommended and those 1816 that pursue this avenue should read this file carefully, as well 1817 as the archives of freebsd-current and freebsd-hackers mailing lists 1818 for potential gotchas. The -U option is also useful to consider. 1819 See mergemaster(8) for more information. 1820 1821 [5] Usually this step is a noop. However, from time to time 1822 you may need to do this if you get unknown user in the following 1823 step. It never hurts to do it all the time. You may need to 1824 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1825 install) after the buildworld before this step if you last updated 1826 from [78]-stable or 9-stable before 20130430. 1827 1828 [6] This only deletes old files and directories. Old libraries 1829 can be deleted by "make delete-old-libs", but you have to make 1830 sure that no program is using those libraries anymore. 1831 1832 [8] In order to have a kernel that can run the 4.x binaries needed to 1833 do an installworld, you must include the COMPAT_FREEBSD4 option in 1834 your kernel. Failure to do so may leave you with a system that is 1835 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1836 required to run the 5.x binaries on more recent kernels. And so on 1837 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1838 1839 Make sure that you merge any new devices from GENERIC since the 1840 last time you updated your kernel config file. 1841 1842 [9] When checking out sources, you must include the -P flag to have 1843 cvs prune empty directories. 1844 1845 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1846 "?=" instead of the "=" assignment operator, so that buildworld can 1847 override the CPUTYPE if it needs to. 1848 1849 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1850 not on the command line, or in /etc/make.conf. buildworld will 1851 warn if it is improperly defined. 1852FORMAT: 1853 1854This file contains a list, in reverse chronological order, of major 1855breakages in tracking -current. It is not guaranteed to be a complete 1856list of such breakages, and only contains entries since October 10, 2007. 1857If you need to see UPDATING entries from before that date, you will need 1858to fetch an UPDATING file from an older FreeBSD release. 1859 1860Copyright information: 1861 1862Copyright 1998-2009 M.
