315 On i386 and amd64 systems, the onifconsole flag is now set by default
316 in /etc/ttys for ttyu0. This causes ttyu0 to be automatically enabled
317 as a login TTY if it is set in the bootloader as an active kernel
318 console. No changes in behavior should result otherwise. To revert to
319 the previous behavior, set ttyu0 to "off" in /etc/ttys.
322 Clang and llvm have been upgraded to 3.4.1 release.
325 Clang and llvm have been upgraded to 3.4 release.
328 The nve(4) driver for NVIDIA nForce MCP Ethernet adapters has
329 been deprecated and will not be part of FreeBSD 11.0 and later
330 releases. If you use this driver, please consider switching to
331 the nfe(4) driver instead.
334 The behavior of gss_pseudo_random() for the krb5 mechanism
335 has changed, for applications requesting a longer random string
336 than produced by the underlying enctype's pseudo-random() function.
337 In particular, the random string produced from a session key of
338 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
339 be different at the 17th octet and later, after this change.
340 The counter used in the PRF+ construction is now encoded as a
341 big-endian integer in accordance with RFC 4402.
342 __FreeBSD_version is bumped to 902505.
348 Behavior of devfs rules path matching has been changed.
349 Pattern is now always matched against fully qualified devfs
350 path and slash characters must be explicitly matched by
351 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs
352 subdirectories must be reviewed.
355 hastctl(8)'s `status' command output changed to terse one-liner format.
356 Scripts using this should switch to `list' command or be rewritten.
359 Fix a bug that allowed a tracing process (e.g. gdb) to write
360 to a memory-mapped file in the traced process's address space
361 even if neither the traced process nor the tracing process had
362 write access to that file.
365 Added ZFS TRIM support which is enabled by default. To disable
366 ZFS TRIM support set vfs.zfs.trim.enabled=0 in loader.conf.
368 Creating new ZFS pools and adding new devices to existing pools
369 first performs a full device level TRIM which can take a significant
370 amount of time. The sysctl vfs.zfs.vdev.trim_on_init can be set to 0
371 to disable this behaviour.
373 ZFS TRIM requires the underlying device support BIO_DELETE which
374 is currently provided by methods such as ATA TRIM and SCSI UNMAP
375 via CAM, which are typically supported by SSD's.
377 Stats for ZFS TRIM can be monitored by looking at the sysctl's
378 under kstat.zfs.misc.zio_trim.
381 `list' command has been added to hastctl(8). For now, it is full
382 equivalent of `status' command.
383 WARNING: in the near future the output of hastctl's status command
384 will change to more terse format. If you use `hastctl status'
385 for parsing in your scripts, switch to `hastctl list'.
388 The mergemaster command now uses the default MAKEOBJDIRPREFIX
389 rather than creating it's own in the temporary directory in
390 order allow access to bootstrapped versions of tools such as
391 install and mtree. When upgrading from version of FreeBSD where
392 the install command does not support -l, you will need to
393 install a new mergemaster command if mergemaster -p is required.
394 This can be accomplished with the command (cd src/usr.sbin/mergemaster
397 Due to the use of the new -l option to install(1) during build
398 and install, you must take care not to directly set the INSTALL
399 make variable in your /etc/make.conf, /etc/src.conf, or on the
400 command line. If you wish to use the -C flag for all installs
401 you may be able to add INSTALL+=-C to /etc/make.conf or
405 Fix a bug that allows NFS clients to issue READDIR on files.
408 The install(1) option -M has changed meaning and now takes an
409 argument that is a file or path to append logs to. In the
410 unlikely event that -M was the last option on the command line
411 and the command line contained at least two files and a target
412 directory the first file will have logs appended to it. The -M
413 option served little practical purpose in the last decade so it's
414 used expected to be extremely rare.
417 A new compression method (lz4) has been merged to. Please refer to
418 zpool-features(7) for more information.
420 Please refer to the "ZFS notes" section of this file for information
421 on upgrading boot ZFS pools.
424 The VFS KBI was changed with the merge of several nullfs
425 optimizations and fixes. All filesystem modules must be
429 With the addition of auditdistd(8), a new auditdistd user is now
430 depended on during installworld. "mergemaster -p" can be used to add
431 the user prior to installworld, as documented in the handbook.
437 A new version of ZFS (pool version 5000) has been merged to 9-STABLE.
438 Starting with this version the old system of ZFS pool versioning
439 is superseded by "feature flags". This concept enables forward
440 compatibility against certain future changes in functionality of ZFS
441 pools. The first two read-only compatible "feature flags" for ZFS
442 pools are "com.delphix:async_destroy" and "com.delphix:empty_bpobj".
443 For more information read the new zpool-features(7) manual page.
444 Please refer to the "ZFS notes" section of this file for information
445 on upgrading boot ZFS pools.
448 The commit introducing bsd.compiler.mk breaks the traditional
449 building of kernels before this point. Add -m ${SRC}/share/mk
450 (for the right value of SRC) to your command lines to work
451 around; update your useland to a point after this; or use the
452 buildkernel/installkernel top-level targets. See also 20120829.
455 The IPFIREWALL_FORWARD kernel option has been removed. Its
456 functionality now turned on by default.
459 The random(4) support for the VIA hardware random number
460 generator (`PADLOCK') is no longer enabled unconditionally.
461 Add the PADLOCK_RNG option in the custom kernel config if
462 needed. The GENERIC kernels on i386 and amd64 do include the
463 option, so the change only affects the custom kernel
467 The amd64 kernel now uses xsetbv, xrstor instructions. To compile with
468 the traditional method, you must update your system with an installworld
469 before the kernel will build. The documented make buildkernel/installkernel
470 interfaces (coupled with fresh make kernel-toolchain) continue to work.
473 The sparc64 ZFS loader has been changed to no longer try to auto-
474 detect ZFS providers based on diskN aliases but now requires these
475 to be explicitly listed in the OFW boot-device environment variable.
478 Now unix domain sockets behave "as expected" on nullfs(5). Previously
479 nullfs(5) did not pass through all behaviours to the underlying layer,
480 as a result if we bound to a socket on the lower layer we could connect
481 only to the lower path; if we bound to the upper layer we could connect
482 only to the upper path. The new behavior is one can connect to both the
483 lower and the upper paths regardless what layer path one binds to.
486 The acpi_wmi(4) status device /dev/wmistat has been renamed to
490 A new VOP_ADVISE() was added to support posix_fadvise(2). All
491 filesystem modules must be recompiled.
494 The interface of the VOP_VPTOCNP(9) changed, now the returned
495 vnode shall be referenced, previously it was required to be
496 only held. All in-tree filesystems are converted.
502 The broken amd(4) driver has been replaced with esp(4) in the amd64,
503 i386 and pc98 GENERIC kernel configuration files.
506 This commit modifies vfs_register() so that it uses a hash
507 calculation to set vfc_typenum, which is enabled by default.
508 The first time a system is booted after this change, the
509 vfc_typenum values will change for all file systems. The
510 main effect of this is a change to the NFS server file handles
511 for file systems that use vfc_typenum in their fsid, such as ZFS.
512 It will, however, prevent vfc_typenum from changing when file
513 systems are loaded in a different order for subsequent reboots.
514 To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf
515 until you are ready to remount all NFS clients after a reboot.
518 Bump the shared library version numbers for libraries that
519 do not use symbol versioning, have changed the ABI compared
520 to stable/8 and which shared library version was not bumped.
521 Done as part of 9.0-RELEASE cycle.
524 During the merge of Capsicum features, the fget(9) KPI was modified.
525 This may require the rebuilding of out-of-tree device drivers --
526 issues have been reported specifically with the nVidia device driver.
527 __FreeBSD_version is bumped to 900041.
529 Also, there is a period between 20110811 and 20110814 where the
530 special devices /dev/{stdin,stdout,stderr} did not work correctly.
531 Building world from a kernel during that window may not work.
534 The packet filter (pf) code has been updated to OpenBSD 4.5.
535 You need to update userland tools to be in sync with kernel.
536 This update breaks backward compatibility with earlier pfsync(4)
537 versions. Care must be taken when updating redundant firewall setups.
540 The following sysctls and tunables are retired on x86 platforms:
542 machdep.hlt_logical_cpus
543 The following sysctl is retired:
544 machdep.hyperthreading_allowed
545 The sysctls were supposed to provide a way to dynamically offline and
546 online selected CPUs on x86 platforms, but the implementation has not
547 been reliable especially with SCHED_ULE scheduler.
548 machdep.hyperthreading_allowed tunable is still available to ignore
549 hyperthreading CPUs at OS level.
550 Individual CPUs can be disabled using hint.lapic.X.disabled tunable,
551 where X is an APIC ID of a CPU. Be advised, though, that disabling
552 CPUs in non-uniform fashion will result in non-uniform topology and
553 may lead to sub-optimal system performance with SCHED_ULE, which is
557 cpumask_t type is retired and cpuset_t is used in order to describe
561 Changes to ifconfig(8) for dynamic address family detection mandate
562 that you are running a kernel of 20110525 or later. Make sure to
563 follow the update procedure to boot a new kernel before installing
567 Support for sun4v architecture is officially dropped
570 Several KPI breaking changes have been committed to the mii(4) layer,
571 the PHY drivers and consequently some Ethernet drivers using mii(4).
572 This means that miibus.ko and the modules of the affected Ethernet
573 drivers need to be recompiled.
575 Note to kernel developers: Given that the OUI bit reversion problem
576 was fixed as part of these changes all mii(4) commits related to OUIs,
577 i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific
578 handling, no longer can be merged verbatim to stable/8 and previous
582 Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci'
583 into their kernel configurations along with 'device pci'.
586 The default NFS client is now the new NFS client, so fstype "newnfs"
587 is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
588 Although mounts via fstype "nfs" will usually work without userland
589 changes, it is recommended that the mount(8) and mount_nfs(8)
590 commands be rebuilt from sources and that a link to mount_nfs called
591 mount_oldnfs be created. The new client is compiled into the
592 kernel with "options NFSCL" and this is needed for diskless root
593 file systems. The GENERIC kernel configs have been changed to use
594 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER.
595 To use the regular/old client, you can "mount -t oldnfs ...". For
596 a diskless root file system, you must also include a line like:
598 vfs.root.mountfrom="oldnfs:"
600 in the boot/loader.conf on the root fs on the NFS server to make
601 a diskless root fs use the old client.
604 The GENERIC kernels for all architectures now default to the new
605 CAM-based ATA stack. It means that all legacy ATA drivers were
606 removed and replaced by respective CAM drivers. If you are using
607 ATA device names in /etc/fstab or other places, make sure to update
608 them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY,
609 where 'Y's are the sequential numbers starting from zero for each type
610 in order of detection, unless configured otherwise with tunables,
611 see cam(4)). There will be symbolic links created in /dev/ to map
612 old adX devices to the respective adaY. They should provide basic
613 compatibility for file systems mounting in most cases, but they do
614 not support old user-level APIs and do not have respective providers
615 in GEOM. Consider using updated management tools with new device names.
617 It is possible to load devices ahci, ata, siis and mvs as modules,
618 but option ATA_CAM should remain in kernel configuration to make ata
619 module work as CAM driver supporting legacy ATA controllers. Device ata
620 still can be used in modular fashion (atacore + ...). Modules atadisk
621 and atapi* are not used and won't affect operation in ATA_CAM mode.
622 Note that to use CAM-based ATA kernel should include CAM devices
623 scbus, pass, da (or explicitly ada), cd and optionally others. All of
624 them are parts of the cam module.
626 ataraid(4) functionality is now supported by the RAID GEOM class.
627 To use it you can load geom_raid kernel module and use graid(8) tool
628 for management. Instead of /dev/arX device names, use /dev/raid/rX.
630 No kernel config options or code have been removed, so if a problem
631 arises, please report it and optionally revert to the old ATA stack.
632 In order to do it you can remove from the kernel config:
637 , and instead add back:
638 device atadisk # ATA disk drives
639 device ataraid # ATA RAID drives
640 device atapicd # ATAPI CDROM drives
641 device atapifd # ATAPI floppy drives
642 device atapist # ATAPI tape drives
645 The default NFS server has been changed to the new server, which
646 was referred to as the experimental server. If you need to switch
647 back to the old NFS server, you must now put the "-o" option on
648 both the mountd and nfsd commands. This can be done using the
649 mountd_flags and nfs_server_flags rc.conf variables until an
650 update to the rc scripts is committed, which is coming soon.
653 The GNU Objective-C runtime library (libobjc), and other Objective-C
654 related components have been removed from the base system. If you
655 require an Objective-C library, please use one of the available ports.
658 ath(4) has been split into bus- and device- modules. if_ath contains
659 the HAL, the TX rate control and the network device code. if_ath_pci
660 contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb
661 contains the AHB glue. Users need to load both if_ath_pci and if_ath
662 in order to use ath on everything else.
664 TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only
665 need to load if_ath and if_ath_pci for ath(4) operation.
668 As part of the replacement of sysinstall, the process of building
669 release media has changed significantly. For details, please re-read
670 release(7), which has been updated to reflect the new build process.
673 GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This
674 is the last available version under GPLv2. It brings a number of new
675 features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE
676 4.1 and SSE 4.2), better support for powerpc64, a number of new
677 directives, and lots of other small improvements. See the ChangeLog
678 file in contrib/binutils for the full details.
681 IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868
682 compliant, and will now use half of hash for authentication.
683 This will break interoperability with all stacks (including all
684 actual FreeBSD versions) who implement
685 draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for
687 The only workaround with such peers is to use another HMAC
688 algorithm for IPsec ("phase 2") authentication.
691 Remove the uio_yield prototype and symbol. This function has
692 been misnamed since it was introduced and should not be
693 globally exposed with this name. The equivalent functionality
694 is now available using kern_yield(curthread->td_user_pri).
695 The function remains undocumented.
698 A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers,
699 symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking
700 for scalar sysctls is defined but disabled. Code that needs
701 UQUAD to pass the type checking that must compile on older
702 systems where the define is not present can check against
703 __FreeBSD_version >= 900030.
705 The system dialog(1) has been replaced with a new version previously
706 in ports as devel/cdialog. dialog(1) is mostly command-line compatible
707 with the previous version, but the libdialog associated with it has
708 a largely incompatible API. As such, the original version of libdialog
709 will be kept temporarily as libodialog, until its base system consumers
710 are replaced or updated. Bump __FreeBSD_version to 900030.
713 If you are trying to run make universe on a -stable system, and you get
714 the following warning:
715 "Makefile", line 356: "Target architecture for i386/conf/GENERIC
716 unknown. config(8) likely too old."
717 or something similar to it, then you must upgrade your -stable system
718 to 8.2-Release or newer (really, any time after r210146 7/15/2010 in
719 stable/8) or build the config from the latest stable/8 branch and
720 install it on your system.
722 Prior to this date, building a current universe on 8-stable system from
723 between 7/15/2010 and 1/2/2011 would result in a weird shell parsing
724 error in the first kernel build phase. A new config on those old
725 systems will fix that problem for older versions of -current.
728 The TCP stack has been modified to allow Khelp modules to interact with
729 it via helper hook points and store per-connection data in the TCP
730 control block. Bump __FreeBSD_version to 900029. User space tools that
731 rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to
735 Generic IEEE 802.3 annex 31B full duplex flow control support has been
736 added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along
737 with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted
738 to take advantage of it instead of using custom implementations. This
739 means that these drivers now no longer unconditionally advertise
740 support for flow control but only do so if flow control is a selected
741 media option. This was implemented in the generic support that way in
742 order to allow flow control to be switched on and off via ifconfig(8)
743 with the PHY specific default to typically off in order to protect
744 from unwanted effects. Consequently, if you used flow control with
745 one of the above mentioned drivers you now need to explicitly enable
747 ifconfig bge0 media auto mediaopt flowcontrol
749 Along with the above mentioned changes generic support for setting
750 1000baseT master mode also has been added and brgphy(4), ciphy(4),
751 e1000phy(4) as well as ip1000phy(4) have been converted to take
752 advantage of it. This means that these drivers now no longer take the
753 link0 parameter for selecting master mode but the master media option
754 has to be used instead, for example like in the following:
755 ifconfig bge0 media 1000baseT mediaopt full-duplex,master
757 Selection of master mode now is also available with all other PHY
758 drivers supporting 1000baseT.
761 The TCP stack has received a significant update to add support for
762 modularised congestion control and generally improve the clarity of
763 congestion control decisions. Bump __FreeBSD_version to 900025. User
764 space tools that rely on the size of struct tcpcb in tcp_var.h (e.g.
765 sockstat) need to be recompiled.
768 The man(1) utility has been replaced by a new version that no longer
769 uses /etc/manpath.config. Please consult man.conf(5) for how to
770 migrate local entries to the new format.
773 The copyright strings printed by login(1) and sshd(8) at the time of a
774 new connection have been removed to follow other operating systems and
778 A workaround for a fixed ld bug has been removed in kernel code,
779 so make sure that your system ld is built from sources after
780 revision 210245 from 2010-07-19 (r211583 if building head kernel
781 on stable/8, r211584 for stable/7; both from 2010-08-21).
782 A symptom of incorrect ld version is different addresses for
783 set_pcpu section and __start_set_pcpu symbol in kernel and/or modules.
786 The $ipv6_prefer variable in rc.conf(5) has been split into
787 $ip6addrctl_policy and $ipv6_activate_all_interfaces.
789 The $ip6addrctl_policy is a variable to choose a pre-defined
790 address selection policy set by ip6addrctl(8). A value
791 "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The
794 The $ipv6_activate_all_interfaces specifies whether IFDISABLED
795 flag (see an entry of 20090926) is set on an interface with no
796 corresponding $ifconfig_IF_ipv6 line. The default is "NO" for
797 security reason. If you want IPv6 link-local address on all
798 interfaces by default, set this to "YES".
800 The old ipv6_prefer="YES" is equivalent to
801 ipv6_activate_all_interfaces="YES" and
802 ip6addrctl_policy="ipv6_prefer".
805 DTrace has grown support for userland tracing. Due to this, DTrace is
806 now i386 and amd64 only.
807 dtruss(1) is now installed by default on those systems and a new
808 kernel module is needed for userland tracing: fasttrap.
809 No changes to your kernel config file are necessary to enable
810 userland tracing, but you might consider adding 'STRIP=' and
811 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want
812 to have informative userland stack traces in DTrace (ustack).
815 The acpi_aiboost(4) driver has been removed in favor of the new
816 aibs(4) driver. You should update your kernel configuration file.
819 BSD grep has been imported to the base system and it is built by
820 default. It is completely BSD licensed, highly GNU-compatible, uses
821 less memory than its GNU counterpart and has a small codebase.
822 However, it is slower than its GNU counterpart, which is mostly
823 noticeable for larger searches, for smaller ones it is measurable
824 but not significant. The reason is complex, the most important factor
825 is that we lack a modern and efficient regex library and GNU
826 overcomes this by optimizing the searches internally. Future work
827 on improving the regex performance is planned, for the meantime,
828 users that need better performance, can build GNU grep instead by
829 setting the WITH_GNU_GREP knob.
832 Due to the import of powerpc64 support, all existing powerpc kernel
833 configuration files must be updated with a machine directive like this:
834 machine powerpc powerpc
836 In addition, an updated config(8) is required to build powerpc kernels
840 A new version of ZFS (version 15) has been merged to -HEAD.
841 This version uses a python library for the following subcommands:
842 zfs allow, zfs unallow, zfs groupspace, zfs userspace.
843 For full functionality of these commands the following port must
844 be installed: sysutils/py-zfs
847 'vm_page's are now hashed by physical address to an array of mutexes.
848 Currently this is only used to serialize access to hold_count. Over
849 time the page queue mutex will be peeled away. This changes the size
850 of pmap on every architecture. And requires all callers of vm_page_hold
851 and vm_page_unhold to be updated.
854 WITH_CTF can now be specified in src.conf (not recommended, there
855 are some problems with static executables), make.conf (would also
856 affect ports which do not use GNU make and do not override the
857 compile targets) or in the kernel config (via "makeoptions
859 When WITH_CTF was specified there before this was silently ignored,
860 so make sure that WITH_CTF is not used in places which could lead
861 to unwanted behavior.
864 The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32
865 to allow 32-bit compatibility on non-x86 platforms. All kernel
866 configurations on amd64 and ia64 platforms using these options must
867 be modified accordingly.
870 The utmp user accounting database has been replaced with utmpx,
871 the user accounting interface standardized by POSIX.
872 Unfortunately the semantics of utmp and utmpx don't match,
873 making it practically impossible to support both interfaces.
874 The user accounting database is used by tools like finger(1),
875 last(1), talk(1), w(1) and ac(8).
877 All applications in the base system use utmpx. This means only
878 local binaries (e.g. from the ports tree) may still use these
879 utmp database files. These applications must be rebuilt to make
882 After the system has been upgraded, it is safe to remove the old
883 log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*),
884 assuming their contents is of no importance anymore. Old wtmp
885 databases can only be used by last(1) and ac(8) after they have
886 been converted to the new format using wtmpcvt(1).
889 Introduce the kernel thread "deadlock resolver" (which can be enabled
890 via the DEADLKRES option, see NOTES for more details) and the
891 sleepq_type() function for sleepqueues.
894 The rc.firewall and rc.firewall6 were unified, and
895 rc.firewall6 and rc.d/ip6fw were removed.
896 According to the removal of rc.d/ip6fw, ipv6_firewall_* rc
897 variables are obsoleted. Instead, the following new rc
898 variables are added to rc.d/ipfw:
900 firewall_client_net_ipv6, firewall_simple_iif_ipv6,
901 firewall_simple_inet_ipv6, firewall_simple_oif_ipv6,
902 firewall_simple_onet_ipv6, firewall_trusted_ipv6
904 The meanings correspond to the relevant IPv4 variables.
910 The default terminal emulation for syscons(4) has been changed
911 from cons25 to xterm on all platforms except pc98. This means
912 that the /etc/ttys file needs to be updated to ensure correct
913 operation of applications on the console.
915 The terminal emulation style can be toggled per window by using
916 vidcontrol(1)'s -T flag. The TEKEN_CONS25 kernel configuration
917 options can be used to change the compile-time default back to
920 To prevent graphical artifacts, make sure the TERM environment
921 variable is set to match the terminal emulation that is being
922 performed by syscons(4).
925 The layout of the structure ieee80211req_scan_result has changed.
926 Applications that require wireless scan results (e.g. ifconfig(8))
927 from net80211 need to be recompiled.
929 Applications such as wpa_supplicant(8) may require a full world
930 build without using NO_CLEAN in order to get synchronized with the
934 The iwn(4) driver has been updated to support the 5000 and 5150 series.
935 There's one kernel module for each firmware. Adding "device iwnfw"
936 to the kernel configuration file means including all three firmware
937 images inside the kernel. If you want to include just the one for
938 your wireless card, use the devices iwn4965fw, iwn5000fw or
942 The rc.d/network_ipv6, IPv6 configuration script has been integrated
943 into rc.d/netif. The changes are the following:
945 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF
946 for IPv4. For aliases, $ifconfig_IF_aliasN should be used.
947 Note that both variables need the "inet6" keyword at the head.
949 Do not set $ipv6_network_interfaces manually if you do not
950 understand what you are doing. It is not needed in most cases.
952 $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but
955 2. $ipv6_enable is obsolete. Use $ipv6_prefer and
956 "inet6 accept_rtadv" keyword in ifconfig(8) instead.
958 If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and
959 all configured interfaces have "inet6 accept_rtadv" in the
960 $ifconfig_IF_ipv6. These are for backward compatibility.
962 3. A new variable $ipv6_prefer has been added. If NO, IPv6
963 functionality of interfaces with no corresponding
964 $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag,
965 and the default address selection policy of ip6addrctl(8)
966 is the IPv4-preferred one (see rc.d/ip6addrctl for more details).
967 Note that if you want to configure IPv6 functionality on the
968 disabled interfaces after boot, first you need to clear the flag by
969 using ifconfig(8) like:
971 ifconfig em0 inet6 -ifdisabled
973 If YES, the default address selection policy is set as
976 The default value of $ipv6_prefer is NO.
978 4. If your system need to receive Router Advertisement messages,
979 define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8)
980 scripts automatically invoke rtsol(8) when the interface becomes
981 UP. The Router Advertisement messages are used for SLAAC
982 (State-Less Address AutoConfiguration).
985 802.11s D3.03 support was committed. This is incompatible with the
986 previous code, which was based on D3.0.
989 A sysctl variable net.inet6.ip6.accept_rtadv now sets the default value
990 of a per-interface flag ND6_IFF_ACCEPT_RTADV, not a global knob to
991 control whether accepting Router Advertisement messages or not.
992 Also, a per-interface flag ND6_IFF_AUTO_LINKLOCAL has been added and
993 a sysctl variable net.inet6.ip6.auto_linklocal is its default value.
994 The ifconfig(8) utility now supports these flags.
997 ZFS snapshots are now mounted with MNT_IGNORE flag. Use -v option for
998 mount(8) and -a option for df(1) to see them.
1001 The old tunable hw.bus.devctl_disable has been superseded by
1002 hw.bus.devctl_queue. hw.bus.devctl_disable=1 in loader.conf should be
1003 replaced by hw.bus.devctl_queue=0. The default for this new tunable
1007 Remove the option STOP_NMI. The default action is now to use NMI only
1008 for KDB via the newly introduced function stop_cpus_hard() and
1009 maintain stop_cpus() to just use a normal IPI_STOP on ia32 and amd64.
1012 The stable/8 branch created in subversion. This corresponds to the
1013 RELENG_8 branch in CVS.
1016 Bump the shared library version numbers for all libraries that do not
1017 use symbol versioning as part of the 8.0-RELEASE cycle. Bump
1018 __FreeBSD_version to 800105.
1021 Due to changes in the implementation of virtual network stack support,
1022 all network-related kernel modules must be recompiled. As this change
1023 breaks the ABI, bump __FreeBSD_version to 800104.
1026 The TOE interface to the TCP syncache has been modified to remove
1027 struct tcpopt (<netinet/tcp_var.h>) from the ABI of the network stack.
1028 The cxgb driver is the only TOE consumer affected by this change, and
1029 needs to be recompiled along with the kernel. As this change breaks
1030 the ABI, bump __FreeBSD_version to 800103.
1033 Padding has been added to struct tcpcb, sackhint and tcpstat in
1034 <netinet/tcp_var.h> to facilitate future MFCs and bug fixes whilst
1035 maintaining the ABI. However, this change breaks the ABI, so bump
1036 __FreeBSD_version to 800102. User space tools that rely on the size of
1037 any of these structs (e.g. sockstat) need to be recompiled.
1040 The NFS_LEGACYRPC option has been removed along with the old kernel
1041 RPC implementation that this option selected. Kernel configurations
1042 may need to be adjusted.
1045 The network interface device nodes at /dev/net/<interface> have been
1046 removed. All ioctl operations can be performed the normal way using
1047 routing sockets. The kqueue functionality can generally be replaced
1048 with routing sockets.
1051 The documentation from the FreeBSD Documentation Project (Handbook,
1052 FAQ, etc.) is now installed via packages by sysinstall(8) and under
1053 the /usr/local/share/doc/freebsd directory instead of /usr/share/doc.
1056 The ABI of various structures related to the SYSV IPC API have been
1057 changed. As a result, the COMPAT_FREEBSD[456] and COMPAT_43 kernel
1058 options now all require COMPAT_FREEBSD7. Bump __FreeBSD_version to
1062 Layout of struct vnet has changed as routing related variables were
1063 moved to their own Vimage module. Modules need to be recompiled. Bump
1064 __FreeBSD_version to 800099.
1067 NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024
1068 respectively. As long as no more than 16 groups per process are used,
1069 no changes should be visible. When more than 16 groups are used, old
1070 binaries may fail if they call getgroups() or getgrouplist() with
1071 statically sized storage. Recompiling will work around this, but
1072 applications should be modified to use dynamically allocated storage
1073 for group arrays as POSIX.1-2008 does not cap an implementation's
1074 number of supported groups at NGROUPS_MAX+1 as previous versions did.
1076 NFS and portalfs mounts may also be affected as the list of groups is
1077 truncated to 16. Users of NFS who use more than 16 groups, should
1078 take care that negative group permissions are not used on the exported
1079 file systems as they will not be reliable unless a GSSAPI based
1080 authentication method is used.
1083 The compiling option ADAPTIVE_LOCKMGRS has been introduced. This
1084 option compiles in the support for adaptive spinning for lockmgrs
1085 which want to enable it. The lockinit() function now accepts the flag
1086 LK_ADAPTIVE in order to make the lock object subject to adaptive
1087 spinning when both held in write and read mode.
1090 The layout of the structure returned by IEEE80211_IOC_STA_INFO has
1091 changed. User applications that use this ioctl need to be rebuilt.
1094 The layout of struct thread has changed. Kernel and modules need to
1098 The layout of structs ifnet, domain, protosw and vnet_net has changed.
1099 Kernel modules need to be rebuilt. Bump __FreeBSD_version to 800097.
1102 window(1) has been removed from the base system. It can now be
1103 installed from ports. The port is called misc/window.
1106 The way we are storing and accessing `routing table' entries has
1107 changed. Programs reading the FIB, like netstat, need to be
1111 A new netisr implementation has been added for FreeBSD 8. Network
1112 file system modules, such as igmp, ipdivert, and others, should be
1114 Bump __FreeBSD_version to 800096.
1117 Remove the tunable/sysctl debug.mpsafevfs as its initial purpose is no
1121 Add VOP_ACCESSX(9). File system modules need to be rebuilt.
1122 Bump __FreeBSD_version to 800094.
1125 Add mnt_xflag field to 'struct mount'. File system modules need to be
1127 Bump __FreeBSD_version to 800093.
1130 The compiling option ADAPTIVE_SX has been retired while it has been
1131 introduced the option NO_ADAPTIVE_SX which handles the reversed logic.
1132 The KPI for sx_init_flags() changes as accepting flags:
1133 SX_ADAPTIVESPIN flag has been retired while the SX_NOADAPTIVE flag has
1134 been introduced in order to handle the reversed logic.
1135 Bump __FreeBSD_version to 800092.
1138 Add support for hierarchical jails. Remove global securelevel.
1139 Bump __FreeBSD_version to 800091.
1142 The layout of struct vnet_net has changed, therefore modules
1144 Bump __FreeBSD_version to 800090.
1147 The newly imported zic(8) produces a new format in the output. Please
1148 run tzsetup(8) to install the newly created data to /etc/localtime.
1151 The sysctl tree for the usb stack has renamed from hw.usb2.* to
1152 hw.usb.* and is now consistent again with previous releases.
1155 802.11 monitor mode support was revised and driver api's were changed.
1156 Drivers dependent on net80211 now support DLT_IEEE802_11_RADIO instead
1157 of DLT_IEEE802_11. No user-visible data structures were changed but
1158 applications that use DLT_IEEE802_11 may require changes.
1159 Bump __FreeBSD_version to 800088.
1162 The layout of the following structs has changed: sysctl_oid,
1163 socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet,
1164 vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or
1165 panics may be experienced. World rebuild is required for
1166 correctly checking networking state from userland.
1167 Bump __FreeBSD_version to 800085.
1170 MLDv2 and Source-Specific Multicast (SSM) have been merged
1171 to the IPv6 stack. VIMAGE hooks are in but not yet used.
1172 The implementation of SSM within FreeBSD's IPv6 stack closely
1173 follows the IPv4 implementation.
1175 For kernel developers:
1177 * The most important changes are that the ip6_output() and
1178 ip6_input() paths no longer take the IN6_MULTI_LOCK,
1179 and this lock has been downgraded to a non-recursive mutex.
1181 * As with the changes to the IPv4 stack to support SSM, filtering
1182 of inbound multicast traffic must now be performed by transport
1183 protocols within the IPv6 stack. This does not apply to TCP and
1184 SCTP, however, it does apply to UDP in IPv6 and raw IPv6.
1186 * The KPIs used by IPv6 multicast are similar to those used by
1187 the IPv4 stack, with the following differences:
1188 * im6o_mc_filter() is analogous to imo_multicast_filter().
1189 * The legacy KAME entry points in6_joingroup and in6_leavegroup()
1190 are shimmed to in6_mc_join() and in6_mc_leave() respectively.
1191 * IN6_LOOKUP_MULTI() has been deprecated and removed.
1192 * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs
1193 for MLDv1 have an additional 'timer' argument which is used to
1194 jitter the initial membership report for the solicited-node
1195 multicast membership on-link.
1196 * This is not strictly needed for MLDv2, which already jitters
1197 its report transmissions. However, the 'timer' argument is
1198 preserved in case MLDv1 is active on the interface.
1200 * The KAME linked-list based IPv6 membership implementation has
1201 been refactored to use a vector similar to that used by the IPv4
1203 Code which maintains a list of its own multicast memberships
1204 internally, e.g. carp, has been updated to reflect the new
1207 * There is a known Lock Order Reversal (LOR) due to in6_setscope()
1208 acquiring the IF_AFDATA_LOCK and being called within ip6_output().
1209 Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an
1210 implementation constraint which needs to be addressed in HEAD.
1212 For application developers:
1214 * The changes are broadly similar to those made for the IPv4
1217 * The use of IPv4 and IPv6 multicast socket options on the same
1218 socket, using mapped addresses, HAS NOT been tested or supported.
1220 * There are a number of issues with the implementation of various
1221 IPv6 multicast APIs which need to be resolved in the API surface
1222 before the implementation is fully compatible with KAME userland
1223 use, and these are mostly to do with interface index treatment.
1225 * The literature available discusses the use of either the delta / ASM
1226 API with setsockopt(2)/getsockopt(2), or the full-state / ASM API
1227 using setsourcefilter(3)/getsourcefilter(3). For more information
1228 please refer to RFC 3768, 'Socket Interface Extensions for
1229 Multicast Source Filters'.
1231 * Applications which use the published RFC 3678 APIs should be fine.
1233 For systems administrators:
1235 * The mtest(8) utility has been refactored to support IPv6, in
1236 addition to IPv4. Interface addresses are no longer accepted
1237 as arguments, their names must be used instead. The utility
1238 will map the interface name to its first IPv4 address as
1239 returned by getifaddrs(3).
1241 * The ifmcstat(8) utility has also been updated to print the MLDv2
1242 endpoint state and source filter lists via sysctl(3).
1244 * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable
1245 loopback of IPv6 multicast datagrams by default; it defaults to 1
1246 to preserve the existing behaviour. Disabling multicast loopback is
1247 recommended for optimal system performance.
1249 * The IPv6 MROUTING code has been changed to examine this sysctl
1250 instead of attempting to perform a group lookup before looping
1251 back forwarded datagrams.
1253 Bump __FreeBSD_version to 800084.
1256 Implement low-level Bluetooth HCI API.
1257 Bump __FreeBSD_version to 800083.
1260 The layout of struct malloc_type, used by modules to register new
1261 memory allocation types, has changed. Most modules will need to
1262 be rebuilt or panics may be experienced.
1263 Bump __FreeBSD_version to 800081.
1266 Anticipate overflowing inp_flags - add inp_flags2.
1267 This changes most offsets in inpcb, so checking v4 connection
1268 state will require a world rebuild.
1269 Bump __FreeBSD_version to 800080.
1272 Add an llentry to struct route and struct route_in6. Modules
1273 embedding a struct route will need to be recompiled.
1274 Bump __FreeBSD_version to 800079.
1277 The size of rt_metrics_lite and by extension rtentry has changed.
1278 Networking administration apps will need to be recompiled.
1279 The route command now supports show as an alias for get, weighting
1280 of routes, sticky and nostick flags to alter the behavior of stateful
1282 Bump __FreeBSD_version to 800078.
1285 Do not use Giant for kbdmux(4) locking. This is wrong and
1286 apparently causing more problems than it solves. This will
1287 re-open the issue where interrupt handlers may race with
1288 kbdmux(4) in polling mode. Typical symptoms include (but
1289 not limited to) duplicated and/or missing characters when
1290 low level console functions (such as gets) are used while
1291 interrupts are enabled (for example geli password prompt,
1292 mountroot prompt etc.). Disabling kbdmux(4) may help.
1295 The size of structs vnet_net, vnet_inet and vnet_ipfw has changed;
1296 kernel modules referencing any of the above need to be recompiled.
1297 Bump __FreeBSD_version to 800075.
1300 GEOM_PART has become the default partition slicer for storage devices,
1301 replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It
1302 introduces some changes:
1304 MSDOS/EBR: the devices created from MSDOS extended partition entries
1305 (EBR) can be named differently than with GEOM_MBR and are now symlinks
1306 to devices with offset-based names. fstabs may need to be modified.
1308 BSD: the "geometry does not match label" warning is harmless in most
1309 cases but it points to problems in file system misalignment with
1310 disk geometry. The "c" partition is now implicit, covers the whole
1311 top-level drive and cannot be (mis)used by users.
1313 General: Kernel dumps are now not allowed to be written to devices
1314 whose partition types indicate they are meant to be used for file
1315 systems (or, in case of MSDOS partitions, as something else than
1318 Most of these changes date approximately from 200812.
1321 The uscanner(4) driver has been removed from the kernel. This follows
1322 Linux removing theirs in 2.6 and making libusb the default interface
1323 (supported by sane).
1326 The multicast forwarding code has been cleaned up. netstat(1)
1327 only relies on KVM now for printing bandwidth upcall meters.
1328 The IPv4 and IPv6 modules are split into ip_mroute_mod and
1329 ip6_mroute_mod respectively. The config(5) options for statically
1330 compiling this code remain the same, i.e. 'options MROUTING'.
1333 Support for the IFF_NEEDSGIANT network interface flag has been
1334 removed, which means that non-MPSAFE network device drivers are no
1335 longer supported. In particular, if_ar, if_sr, and network device
1336 drivers from the old (legacy) USB stack can no longer be built or
1340 POSIX.1 Native Language Support (NLS) has been enabled in libc and
1341 a bunch of new language catalog files have also been added.
1342 This means that some common libc messages are now localized and
1343 they depend on the LC_MESSAGES environmental variable.
1346 The k8temp(4) driver has been renamed to amdtemp(4) since
1347 support for Family 10 and Family 11 CPU families was added.
1350 IGMPv3 and Source-Specific Multicast (SSM) have been merged
1351 to the IPv4 stack. VIMAGE hooks are in but not yet used.
1353 For kernel developers, the most important changes are that the
1354 ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(),
1355 and this lock has been downgraded to a non-recursive mutex.
1357 Transport protocols (UDP, Raw IP) are now responsible for filtering
1358 inbound multicast traffic according to group membership and source
1359 filters. The imo_multicast_filter() KPI exists for this purpose.
1360 Transports which do not use multicast (SCTP, TCP) already reject
1361 multicast by default. Forwarding and receive performance may improve
1362 as a mutex acquisition is no longer needed in the ip_input()
1363 low-level input path. in_addmulti() and in_delmulti() are shimmed
1364 to new KPIs which exist to support SSM in-kernel.
1366 For application developers, it is recommended that loopback of
1367 multicast datagrams be disabled for best performance, as this
1368 will still cause the lock to be taken for each looped-back
1369 datagram transmission. The net.inet.ip.mcast.loop sysctl may
1370 be tuned to 0 to disable loopback by default; it defaults to 1
1371 to preserve the existing behaviour.
1373 For systems administrators, to obtain best performance with
1374 multicast reception and multiple groups, it is always recommended
1375 that a card with a suitably precise hash filter is used. Hash
1376 collisions will still result in the lock being taken within the
1377 transport protocol input path to check group membership.
1379 If deploying FreeBSD in an environment with IGMP snooping switches,
1380 it is recommended that the net.inet.igmp.sendlocal sysctl remain
1381 enabled; this forces 224.0.0.0/24 group membership to be announced
1384 The size of 'struct igmpstat' has changed; netstat needs to be
1385 recompiled to reflect this.
1386 Bump __FreeBSD_version to 800070.
1389 libusb20.so.1 is now installed as libusb.so.1 and the ports system
1390 updated to use it. This requires a buildworld/installworld in order to
1391 update the library and dependencies (usbconfig, etc). Its advisable to
1392 rebuild all ports which uses libusb. More specific directions are given
1393 in the ports collection UPDATING file. Any /etc/libmap.conf entries for
1394 libusb are no longer required and can be removed.
1397 A workaround is committed to allow the creation of System V shared
1398 memory segment of size > 2 GB on the 64-bit architectures.
1399 Due to a limitation of the existing ABI, the shm_segsz member
1400 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is
1401 wrong for large segments. Note that limits must be explicitly
1402 raised to allow such segments to be created.
1405 The layout of struct ifnet has changed, requiring a rebuild of all
1406 network device driver modules.
1409 The /dev handling for the new USB stack has changed, a
1410 buildworld/installworld is required for libusb20.
1413 The new USB2 stack has now been permanently moved in and all kernel and
1414 module names reverted to their previous values (eg, usb, ehci, ohci,
1415 ums, ...). The old usb stack can be compiled in by prefixing the name
1416 with the letter 'o', the old usb modules have been removed.
1417 Updating entry 20090216 for xorg and 20090215 for libmap may still
1421 The rc.conf(5) option if_up_delay has been renamed to
1422 defaultroute_delay to better reflect its purpose. If you have
1423 customized this setting in /etc/rc.conf you need to update it to
1427 xorg 7.4 wants to configure its input devices via hald which does not
1428 yet work with USB2. If the keyboard/mouse does not work in xorg then
1430 Option "AllowEmptyInput" "off"
1431 to your ServerLayout section. This will cause X to use the configured
1432 kbd and mouse sections from your xorg.conf.
1435 The GENERIC kernels for all architectures now default to the new USB2
1436 stack. No kernel config options or code have been removed so if a
1437 problem arises please report it and optionally revert to the old USB
1438 stack. If you are loading USB kernel modules or have a custom kernel
1439 that includes GENERIC then ensure that usb names are also changed over,
1440 eg uftdi -> usb2_serial_ftdi.
1442 Older programs linked against the ports libusb 0.1 need to be
1443 redirected to the new stack's libusb20. /etc/libmap.conf can
1445 # Map old usb library to new one for usb2 stack
1446 libusb-0.1.so.8 libusb20.so.1
1449 All USB ethernet devices now attach as interfaces under the name ueN
1450 (eg. ue0). This is to provide a predictable name as vendors often
1451 change usb chipsets in a product without notice.
1454 The ichsmb(4) driver has been changed to require SMBus slave
1455 addresses be left-justified (xxxxxxx0b) rather than right-justified.
1456 All of the other SMBus controller drivers require left-justified
1457 slave addresses, so this change makes all the drivers provide the
1461 INET6 statistics (struct ip6stat) was updated.
1462 netstat(1) needs to be recompiled.
1465 NTFS has been removed from GENERIC kernel on amd64 to match
1466 GENERIC on i386. Should not cause any issues since mount_ntfs(8)
1467 will load ntfs.ko module automatically when NTFS support is
1468 actually needed, unless ntfs.ko is not installed or security
1469 level prohibits loading kernel modules. If either is the case,
1470 "options NTFS" has to be added into kernel config.
1473 TCP Appropriate Byte Counting (RFC 3465) support added to kernel.
1474 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to
1475 800061. User space tools that rely on the size of struct tcpcb in
1476 tcp_var.h (e.g. sockstat) need to be recompiled.
1479 ng_tty(4) module updated to match the new TTY subsystem.
1480 Due to API change, user-level applications must be updated.
1481 New API support added to mpd5 CVS and expected to be present
1482 in next mpd5.3 release.
1485 With __FreeBSD_version 800060 the makefs tool is part of
1486 the base system (it was a port).
1489 The afdata and ifnet locks have been changed from mutexes to
1490 rwlocks, network modules will need to be re-compiled.
1493 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite.
1494 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated.
1495 The new code reduced struct rtentry{} by 16 bytes on 32-bit
1496 architecture and 40 bytes on 64-bit architecture. The userland
1497 applications "arp" and "ndp" have been updated accordingly.
1498 The output from "netstat -r" shows only routing entries and
1499 none of the L2 information.
1502 __FreeBSD_version 800057 marks the switchover from the
1503 binary ath hal to source code. Users must add the line:
1505 options AH_SUPPORT_AR5416
1507 to their kernel config files when specifying:
1511 The ath_hal module no longer exists; the code is now compiled
1512 together with the driver in the ath module. It is now
1513 possible to tailor chip support (i.e. reduce the set of chips
1514 and thereby the code size); consult ath_hal(4) for details.
1517 __FreeBSD_version 800054 adds memory barriers to
1518 <machine/atomic.h>, new interfaces to ifnet to facilitate
1519 multiple hardware transmit queues for cards that support
1520 them, and a lock-less ring-buffer implementation to
1521 enable drivers to more efficiently manage queueing of
1525 A new version of ZFS (version 13) has been merged to -HEAD.
1526 This version has zpool attribute "listsnapshots" off by
1527 default, which means "zfs list" does not show snapshots,
1528 and is the same as Solaris behavior.
1531 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled.
1534 The uhci, ohci, ehci and slhci USB Host controller drivers have
1535 been put into separate modules. If you load the usb module
1536 separately through loader.conf you will need to load the
1537 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0
1538 controller add the following to loader.conf:
1544 The ABI used by the PMC toolset has changed. Please keep
1545 userland (libpmc(3)) and the kernel module (hwpmc(4)) in
1549 atapci kernel module now includes only generic PCI ATA
1550 driver. AHCI driver moved to ataahci kernel module.
1551 All vendor-specific code moved into separate kernel modules:
1552 ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek,
1553 atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron,
1554 atamarvell, atamicron, atanational, atanetcell, atanvidia,
1555 atapromise, ataserverworks, atasiliconimage, atasis, atavia
1558 The TTY subsystem of the kernel has been replaced by a new
1559 implementation, which provides better scalability and an
1560 improved driver model. Most common drivers have been migrated to
1561 the new TTY subsystem, while others have not. The following
1562 drivers have not yet been ported to the new TTY layer:
1565 cy, digi, rc, rp, sio
1571 ng_h4, ng_tty, ppp, sl, snp
1573 Adding these drivers to your kernel configuration file shall
1574 cause compilation to fail.
1577 ntpd has been upgraded to 4.2.4p5.
1580 OpenSSH has been upgraded to 5.1p1.
1582 For many years, FreeBSD's version of OpenSSH preferred DSA
1583 over RSA for host and user authentication keys. With this
1584 upgrade, we've switched to the vendor's default of RSA over
1585 DSA. This may cause upgraded clients to warn about unknown
1586 host keys even for previously known hosts. Users should
1587 follow the usual procedure for verifying host keys before
1588 accepting the RSA key.
1590 This can be circumvented by setting the "HostKeyAlgorithms"
1591 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh
1594 Please note that the sequence of keys offered for
1595 authentication has been changed as well. You may want to
1596 specify IdentityFile in a different order to revert this
1600 The sio(4) driver has been removed from the i386 and amd64
1601 kernel configuration files. This means uart(4) is now the
1602 default serial port driver on those platforms as well.
1604 To prevent collisions with the sio(4) driver, the uart(4) driver
1605 uses different names for its device nodes. This means the
1606 onboard serial port will now most likely be called "ttyu0"
1607 instead of "ttyd0". You may need to reconfigure applications to
1608 use the new device names.
1610 When using the serial port as a boot console, be sure to update
1611 /boot/device.hints and /etc/ttys before booting the new kernel.
1612 If you forget to do so, you can still manually specify the hints
1613 at the loader prompt:
1615 set hint.uart.0.at="isa"
1616 set hint.uart.0.port="0x3F8"
1617 set hint.uart.0.flags="0x10"
1618 set hint.uart.0.irq="4"
1622 The gpt(8) utility has been removed. Use gpart(8) to partition
1626 The version that Linuxulator emulates was changed from 2.4.2
1627 to 2.6.16. If you experience any problems with Linux binaries
1628 please try to set sysctl compat.linux.osrelease to 2.4.2 and
1629 if it fixes the problem contact emulation mailing list.
1632 ISDN4BSD (I4B) was removed from the src tree. You may need to
1633 update a your kernel configuration and remove relevant entries.
1636 I have checked in code to support multiple routing tables.
1637 See the man pages setfib(1) and setfib(2).
1638 This is a hopefully backwards compatible version,
1639 but to make use of it you need to compile your kernel
1640 with options ROUTETABLES=2 (or more up to 16).
1643 The 802.11 wireless support was redone to enable multi-bss
1644 operation on devices that are capable. The underlying device
1645 is no longer used directly but instead wlanX devices are
1646 cloned with ifconfig. This requires changes to rc.conf files.
1647 For example, change:
1648 ifconfig_ath0="WPA DHCP"
1651 ifconfig_wlan0="WPA DHCP"
1652 see rc.conf(5) for more details. In addition, mergemaster of
1653 /etc/rc.d is highly recommended. Simultaneous update of userland
1654 and kernel wouldn't hurt either.
1656 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta
1657 modules were merged into the base wlan module. All references
1658 to these modules (e.g. in kernel config files) must be removed.
1661 psm(4) has gained write(2) support in native operation level.
1662 Arbitrary commands can be written to /dev/psm%d and status can
1663 be read back from it. Therefore, an application is responsible
1664 for status validation and error recovery. It is a no-op in
1665 other operation levels.
1668 Support for KSE threading has been removed from the kernel. To
1669 run legacy applications linked against KSE libmap.conf may
1670 be used. The following libmap.conf may be used to ensure
1671 compatibility with any prior release:
1673 libpthread.so.1 libthr.so.1
1674 libpthread.so.2 libthr.so.2
1675 libkse.so.3 libthr.so.3
1678 The layout of struct vmspace has changed. This affects libkvm
1679 and any executables that link against libkvm and use the
1680 kvm_getprocs() function. In particular, but not exclusively,
1681 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1).
1682 The effects are minimal, but it's advisable to upgrade world
1686 The latest em driver no longer has support in it for the
1687 82575 adapter, this is now moved to the igb driver. The
1688 split was done to make new features that are incompatible
1689 with older hardware easier to do.
1692 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4),
1693 likewise the kernel option is now GEOM_LINUX_LVM.
1696 The default NFS mount mode has changed from UDP to TCP for
1697 increased reliability. If you rely on (insecurely) NFS
1698 mounting across a firewall you may need to update your
1702 Belatedly note the addition of m_collapse for compacting
1706 The fts(3) structures have been changed to use adequate
1707 integer types for their members and so to be able to cope
1708 with huge file trees. The old fts(3) ABI is preserved
1709 through symbol versioning in libc, so third-party binaries
1710 using fts(3) should still work, although they will not take
1711 advantage of the extended types. At the same time, some
1712 third-party software might fail to build after this change
1713 due to unportable assumptions made in its source code about
1714 fts(3) structure members. Such software should be fixed
1715 by its vendor or, in the worst case, in the ports tree.
1716 FreeBSD_version 800015 marks this change for the unlikely
1717 case that a portable fix is impossible.
1720 To upgrade to -current after this date, you must be running
1721 FreeBSD not older than 6.0-RELEASE. Upgrading to -current
1722 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems.
1725 The ADAPTIVE_GIANT kernel option has been retired because its
1726 functionality is the default now.
1729 The AT keyboard emulation of sunkbd(4) has been turned on
1730 by default. In order to make the special symbols of the Sun
1731 keyboards driven by sunkbd(4) work under X these now have
1732 to be configured the same way as Sun USB keyboards driven
1733 by ukbd(4) (which also does AT keyboard emulation), f.e.:
1735 Option "XkbLayout" "us"
1736 Option "XkbRules" "xorg"
1737 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us"
1740 It has been decided that it is desirable to provide ABI
1741 backwards compatibility to the FreeBSD 4/5/6 versions of the
1742 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was
1743 broken with the introduction of PCI domain support (see the
1744 20070930 entry). Unfortunately, this required the ABI of
1745 PCIOCGETCONF to be broken again in order to be able to
1746 provide backwards compatibility to the old version of that
1747 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled
1748 again. As for prominent ports this affects neither pciutils
1749 nor xorg-server this time, the hal port needs to be rebuilt
1753 The misnamed kthread_create() and friends have been renamed
1754 to kproc_create() etc. Many of the callers already
1755 used kproc_start()..
1756 I will return kthread_create() and friends in a while
1757 with implementations that actually create threads, not procs.
1758 Renaming corresponds with version 800002.
1767 Avoid using make -j when upgrading. While generally safe, there are
1768 sometimes problems using -j to upgrade. If your upgrade fails with
1769 -j, please try again without -j. From time to time in the past there
1770 have been problems using -j with buildworld and/or installworld. This
1771 is especially true when upgrading between "distant" versions (eg one
1772 that cross a major release boundary or several minor releases, or when
1773 several months have passed on the -current branch).
1775 Sometimes, obscure build problems are the result of environment
1776 poisoning. This can happen because the make utility reads its
1777 environment when searching for values for global variables. To run
1778 your build attempts in an "environmental clean room", prefix all make
1779 commands with 'env -i '. See the env(1) manual page for more details.
1781 When upgrading from one major version to another it is generally best
1782 to upgrade to the latest code in the currently installed branch first,
1783 then do an upgrade to the new branch. This is the best-tested upgrade
1784 path, and has the highest probability of being successful. Please try
1785 this approach before reporting problems with a major version upgrade.
1789 When upgrading the boot ZFS pool to a new version, always follow
1792 1.) recompile and reinstall the ZFS boot loader and boot block
1793 (this is part of "make buildworld" and "make installworld")
1795 2.) update the ZFS boot block on your boot drive
1797 The following example updates the ZFS boot block on the first
1798 partition (freebsd-boot) of a GPT partitioned drive ad0:
1799 "gpart bootcode -p /boot/gptzfsboot -i 1 ad0"
1801 Non-boot pools do not need these updates.
1805 If you are updating from a prior version of FreeBSD (even one just
1806 a few days old), you should follow this procedure. It is the most
1807 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
1809 make kernel-toolchain
1810 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1811 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1813 To test a kernel once
1814 ---------------------
1815 If you just want to boot a kernel once (because you are not sure
1816 if it works, or if you want to boot a known bad kernel to provide
1817 debugging information) run
1818 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
1819 nextboot -k testkernel
1821 To just build a kernel when you know that it won't mess you up
1822 --------------------------------------------------------------
1823 This assumes you are already running a CURRENT system. Replace
1824 ${arch} with the architecture of your machine (e.g. "i386",
1825 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc).
1827 cd src/sys/${arch}/conf
1828 config KERNEL_NAME_HERE
1829 cd ../compile/KERNEL_NAME_HERE
1834 If this fails, go to the "To build a kernel" section.
1836 To rebuild everything and install it on the current system.
1837 -----------------------------------------------------------
1838 # Note: sometimes if you are running current you gotta do more than
1839 # is listed here if you are upgrading from a really old current.
1841 <make sure you have good level 0 dumps>
1843 make kernel KERNCONF=YOUR_KERNEL_HERE
1845 <reboot in single user> [3]
1853 To cross-install current onto a separate partition
1854 --------------------------------------------------
1855 # In this approach we use a separate partition to hold
1856 # current's root, 'usr', and 'var' directories. A partition
1857 # holding "/", "/usr" and "/var" should be about 2GB in
1860 <make sure you have good level 0 dumps>
1863 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1864 <maybe newfs current's root partition>
1865 <mount current's root partition on directory ${CURRENT_ROOT}>
1866 make installworld DESTDIR=${CURRENT_ROOT}
1867 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1868 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1869 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
1870 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1871 <reboot into current>
1872 <do a "native" rebuild/install as described in the previous section>
1873 <maybe install compatibility libraries from ports/misc/compat*>
1877 To upgrade in-place from stable to current
1878 ----------------------------------------------
1879 <make sure you have good level 0 dumps>
1881 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
1883 <reboot in single user> [3]
1890 Make sure that you've read the UPDATING file to understand the
1891 tweaks to various things you need. At this point in the life
1892 cycle of current, things change often and you are on your own
1893 to cope. The defaults can also change, so please read ALL of
1894 the UPDATING entries.
1896 Also, if you are tracking -current, you must be subscribed to
1897 freebsd-current@freebsd.org. Make sure that before you update
1898 your sources that you have read and understood all the recent
1899 messages there. If in doubt, please track -stable which has
1900 much fewer pitfalls.
1902 [1] If you have third party modules, such as vmware, you
1903 should disable them at this point so they don't crash your
1906 [3] From the bootblocks, boot -s, and then do
1911 adjkerntz -i # if CMOS is wall time
1912 Also, when doing a major release upgrade, it is required that
1913 you boot into single user mode to do the installworld.
1915 [4] Note: This step is non-optional. Failure to do this step
1916 can result in a significant reduction in the functionality of the
1917 system. Attempting to do it by hand is not recommended and those
1918 that pursue this avenue should read this file carefully, as well
1919 as the archives of freebsd-current and freebsd-hackers mailing lists
1920 for potential gotchas. The -U option is also useful to consider.
1921 See mergemaster(8) for more information.
1923 [5] Usually this step is a noop. However, from time to time
1924 you may need to do this if you get unknown user in the following
1925 step. It never hurts to do it all the time. You may need to
1926 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1927 install) after the buildworld before this step if you last updated
1928 from [78]-stable or 9-stable before 20130430.
1930 [6] This only deletes old files and directories. Old libraries
1931 can be deleted by "make delete-old-libs", but you have to make
1932 sure that no program is using those libraries anymore.
1934 [8] In order to have a kernel that can run the 4.x binaries needed to
1935 do an installworld, you must include the COMPAT_FREEBSD4 option in
1936 your kernel. Failure to do so may leave you with a system that is
1937 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is
1938 required to run the 5.x binaries on more recent kernels. And so on
1939 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7.
1941 Make sure that you merge any new devices from GENERIC since the
1942 last time you updated your kernel config file.
1944 [9] When checking out sources, you must include the -P flag to have
1945 cvs prune empty directories.
1947 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1948 "?=" instead of the "=" assignment operator, so that buildworld can
1949 override the CPUTYPE if it needs to.
1951 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1952 not on the command line, or in /etc/make.conf. buildworld will
1953 warn if it is improperly defined.
1956 This file contains a list, in reverse chronological order, of major
1957 breakages in tracking -current. It is not guaranteed to be a complete
1958 list of such breakages, and only contains entries since October 10, 2007.
1959 If you need to see UPDATING entries from before that date, you will need
1960 to fetch an UPDATING file from an older FreeBSD release.
