52 Don't leak information via uninitialized space in db(3) records.
55 Sanity-check string lengths in order to stop OpenSSL crashing
56 when printing corrupt BMPString or UniversalString objects. [09:08]
59 Following bug-fixes to TCP connection state flags, netstat, systat,
60 and sockstat will need to be rebuilt in order to properly print
61 connections in the TIMEWAIT state.
64 Change IPv6 ephemeral port allocation from sequential to
65 random allocation, like IPv4 has done for more than four years.
66 The implementation shares infrastructure with IPv4. This
67 means that there is only one set of sysctls to control both
68 IPv4 and IPv6. See ip(4) man page for details.
71 A workaround is committed to allow the creation of System V shared
72 memory segment of size > 2 GB on the 64-bit architectures.
73 Due to a limitation of the existing ABI, the shm_segsz member
74 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is
75 wrong for large segments. Note that limits must be explicitely
76 raised to allow such segments to be created.
78 The management interface that is used by ipcs(1) has to be changed
79 in incompatible way. Rebuild the ipcs(1) utility with the new
80 headers after the update. Buildworld/installworld takes care
81 of this issue automatically.
84 The open-source Atheros HAL has been merged from HEAD
86 The kernel compile-time option AH_SUPPORT_AR5416 has been
87 added to support certain newer Atheros parts, particularly
89 The following modules are no longer available, and should be
90 removed from MODULES_OVERRIDE and/or loader.conf:-
91 ath_hal ath_rate_amrr ath_rate_onoe ath_rate_sample
94 ZFS users on amd64 machines with 4GB or more of RAM should
95 reevaluate their need for setting vm.kmem_size_max and
96 vm.kmem_size manually. In fact, after recent changes to the
97 kernel, the default value of vm.kmem_size is larger than the
98 suggested manual setting in most ZFS/FreeBSD tuning guides.
101 Multi-IPv4/v6/no-IP jail support was merged to STABLE.
102 You need to rebuild jls(8) and to use the new features
103 jail(8), jexec(8) and cpuset(1) with a new kernel.
104 __FreeBSD_version was bumped to 701103.
107 NTFS has been removed from GENERIC kernel on amd64 to match
108 GENERIC on i386. Should not cause any issues since mount_ntfs(8)
109 will load ntfs.ko module automatically when NTFS support is
110 actually needed, unless ntfs.ko is not installed or security
111 level prohibits loading kernel modules. If either is the case,
112 "options NTFS" has to be added into kernel config.
115 powerd(8) was updated to get better SMP support.
116 Meanings of the -i and -r command line options were changed.
119 snd_hda(4) driver was updated to version 20081226_0122.
121 Due to added HDMI audio and logical audio devices support, updated
122 driver often provides several PCM devices. In some cases it can make
123 system default audio device no longer correspond to the users's
124 habbitual audio connectors. In such cases wanted device can be
125 specified in audio application setup or defined globally via
126 hw.snd.default_unit sysctl according to sound(4) and snd_hda(4)
133 ntpd has been upgraded to 4.2.4p5.
136 OpenSSH has been upgraded to 5.1p1.
139 DTrace support was merged to STABLE today. In the best
140 tradition of "the dog ate my homework", subversion decided
141 that the commit message was too large and opted not to send
142 it. It was a stealth commit!
144 A 'make buildkernel' will now default to build the kernel
145 and modules with both DTrace kernel hooks and CTF data ready
148 After you have installed both world and the kernel, and
149 rebooted, you can 'kldload dtraceall' to load all the DTrace
150 kernel modules and then you're set to run the 'dtrace'
153 For DTrace documentation, refer to:
154 <http://wikis.sun.com/display/DTrace/Documentation>
156 We are limited to kernel tracing at the moment, so the pid
157 provider is not available.
159 For the syscall provider, note that the arguments to the
160 return probes are the same as for the entry probes.
163 Today STABLE got a reorganization of the Intel E1000
164 driver code. In order to better support our new adapters
165 there is a new driver, igb, that is now to be used for
166 either the 82575 or 82576 adapters. The source however,
167 is all now in sys/dev/e1000, both em and igb drivers are
168 built from that common directory if you configure them
169 in the kernel. Making loadable drivers still happens in
170 the same place: sys/modules/[em, igb].
172 The important thing to note is that the 82575 adapters
173 were supported in the em driver in 7.0, but now needed
174 to be moved into igb, so if you have the effected cards
175 be sure and make any script changes to follow the name
178 There are only 3 PCI ID's effected in this change:
179 0x10A7, 0x10A9, and 0x10D6
180 So you can know ahead of time if they will be effected,
181 these will now be supported in the igb driver. That
182 driver will also support the new 82576 followon.
184 The driver reorg in STABLE is inconvenient but it really
185 was necessary for Intel to do this, and I figured it was
186 better to have this small admin type issue than not to
187 have support for this new hardware for a whole release
191 I have MFC'd in code to support multiple routing tables.
192 see the man pages setfib(1) and setfib(2).
193 This is a backwards compatible version,
194 but to make use of it you need to compile your kernel
195 with options ROUTETABLES=2 (or more up to 16).
201 Note the addition of m_collapse for compacting mbuf chains.
204 The AT keyboard emulation of sunkbd(4) has been turned on
205 by default. In order to make the special symbols of the Sun
206 keyboards driven by sunkbd(4) work under X these now have
207 to be configured the same way as Sun USB keyboards driven
208 by ukbd(4) (which also does AT keyboard emulation), f.e.:
210 Option "XkbLayout" "us"
211 Option "XkbRules" "xorg"
212 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us"
215 It has been decided that it is desirable to provide ABI
216 backwards compatibility to the FreeBSD 4/5/6 versions of the
217 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was
218 broken with the introduction of PCI domain support (see the
219 20070930 entry). Unfortunately, this required the ABI of
220 PCIOCGETCONF to be broken again in order to be able to
221 provide backwards compatibility to the old version of that
222 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled
223 again. As for prominent ports this affects neither pciutils
224 nor xorg-server this time, the hal port needs to be rebuilt
231 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and
232 WITHOUT_LIBTHR are set.
235 The PCI code has been made aware of PCI domains. This means that
236 the location strings as used by pciconf(8) etc are now in the
237 following format: pci<domain>:<bus>:<device>[:<function>]. It
238 also means that consumers of <sys/pciio.h> potentially need to
239 be recompiled; this includes the hal and xorg-server ports.
242 The caching daemon (cached) was renamed to nscd. nscd.conf
243 configuration file should be used instead of cached.conf and
244 nscd_enable, nscd_pidfile and nscd_flags options should be used
245 instead of cached_enable, cached_pidfile and cached_flags in
249 The new IPsec code is now compiled in using the IPSEC option. The
250 IPSEC option now requires "device crypto" be defined in your kernel
251 configuration. The FAST_IPSEC kernel option is now deprecated.
254 The packet filter (pf) code has been updated to OpenBSD 4.1 Please
255 note the changed syntax - keep state is now on by default. Also
256 note the fact that ftp-proxy(8) has been changed from bottom up and
257 has been moved from libexec to usr/sbin. Changes in the ALTQ
258 handling also affect users of IPFW's ALTQ capabilities.
261 Remove KAME IPsec in favor of FAST_IPSEC, which is now the
262 only IPsec supported by FreeBSD. The new IPsec stack
263 supports both IPv4 and IPv6. The kernel option will change
264 after the code changes have settled in. For now the kernel
265 option IPSEC is deprecated and FAST_IPSEC is the only option, that
266 will change after some settling time.
269 The wicontrol(8) utility has been removed from the base system. wi(4)
270 cards should be configured using ifconfig(8), see the man page for more
274 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver
275 instead of the nve(4) driver. Please update your configuration
279 By default, /etc/rc.d/sendmail no longer rebuilds the aliases
280 database if it is missing or older than the aliases file. If
281 desired, set the new rc.conf option sendmail_rebuild_aliases
282 to "YES" to restore that functionality.
285 The IPv4 multicast socket code has been considerably modified, and
286 moved to the file sys/netinet/in_mcast.c. Initial support for the
287 RFC 3678 Source-Specific Multicast Socket API has been added to
288 the IPv4 network stack.
290 Strict multicast and broadcast reception is now the default for
291 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable
292 has now been removed.
294 The RFC 1724 hack for interface selection has been removed; the use
295 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has
296 been added to replace it. Consumers such as routed will soon be
297 updated to reflect this.
299 These changes affect users who are running routed(8) or rdisc(8)
300 from the FreeBSD base system on point-to-point or unnumbered
304 The net80211 layer has changed significantly and all wireless
305 drivers that depend on it need to be recompiled. Further these
306 changes require that any program that interacts with the wireless
307 support in the kernel be recompiled; this includes: ifconfig,
308 wpa_supplicant, hostapd, and wlanstats. Users must also, for
309 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules
310 if they use modules for wireless support. These modules implement
311 scanning support for station and ap modes, respectively. Failure
312 to load the appropriate module before marking a wireless interface
313 up will result in a message to the console and the device not
317 The pam_nologin(8) module ceases to provide an authentication
318 function and starts providing an account management function.
319 Consequent changes to /etc/pam.d should be brought in using
320 mergemaster(8). Third-party files in /usr/local/etc/pam.d may
321 need manual editing as follows. Locate this line (or similar):
323 auth required pam_nologin.so no_warn
325 and change it according to this example:
327 account required pam_nologin.so no_warn
329 That is, the first word needs to be changed from "auth" to
330 "account". The new line can be moved to the account section
331 within the file for clarity. Not updating pam.conf(5) files
332 will result in nologin(5) ignored by the respective services.
335 The ether_ioctl() function has been synchronized with ioctl(2)
336 and ifnet.if_ioctl. Due to that, the size of one of its arguments
337 has changed on 64-bit architectures. All kernel modules using
338 ether_ioctl() need to be rebuilt on such architectures.
341 Improved INCLUDE_CONFIG_FILE support has been introduced to the
342 config(8) utility. In order to take advantage of this new
343 functionality, you are expected to recompile and install
344 src/usr.sbin/config. If you don't rebuild config(8), and your
345 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel
346 build will be broken because of a missing "kernconfstring"
350 Symbol versioning is enabled by default. To disable it, use
351 option WITHOUT_SYMVER. It is not advisable to attempt to
352 disable symbol versioning once it is enabled; your installworld
353 will break because a symbol version-less libc will get installed
354 before the install tools. As a result, the old install tools,
355 which previously had symbol dependencies to FBSD_1.0, will fail
356 because the freshly installed libc will not have them.
358 The default threading library (providing "libpthread") has been
359 changed to libthr. If you wish to have libkse as your default,
360 use option DEFAULT_THREAD_LIB=libkse for the buildworld.
363 The ABI breakage in sendmail(8)'s libmilter has been repaired
364 so it is no longer necessary to recompile mail filters (aka,
365 milters). If you recompiled mail filters after the 20070408
366 note, it is not necessary to recompile them again.
369 The new trunk(4) driver has been renamed to lagg(4) as it better
370 reflects its purpose. ifconfig will need to be recompiled.
373 sendmail(8) has been updated to version 8.14.1. Mail filters
374 (aka, milters) compiled against the libmilter included in the
375 base operating system should be recompiled.
378 Firmwares for ipw(4) and iwi(4) are now included in the base tree.
379 In order to use them one must agree to the respective LICENSE in
380 share/doc/legal and define legal.intel_<name>.license_ack=1 via
381 loader.conf(5) or kenv(1). Make sure to deinstall the now
382 deprecated modules from the respective firmware ports.
385 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3)
386 were removed from FreeBSD's libc. These originally came from INRIA
387 IPv6. Nothing in FreeBSD ever used them. They may be regarded as
388 deprecated in previous releases.
389 The AF_LINK support for getnameinfo(3) was merged from NetBSD to
390 replace it as a more portable (and re-entrant) API.
393 To support interrupt filtering a modification to the newbus API
394 has occurred, ABI was broken and __FreeBSD_version was bumped
395 to 700031. Please make sure that your kernel and modules are in
397 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941
400 The IPv6 multicast forwarding code may now be loaded into GENERIC
401 kernels by loading the ip_mroute.ko module. This is built into the
402 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are
403 set; see src.conf(5) for more information.
406 The output of netstat -r has changed. Without -n, we now only
407 print a "network name" without the prefix length if the network
408 address and mask exactly match a Class A/B/C network, and an entry
409 exists in the nsswitch "networks" map.
410 With -n, we print the full unabbreviated CIDR network prefix in
411 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default".
412 This change is in preparation for changes such as equal-cost
413 multipath, and to more generally assist operational deployment
414 of FreeBSD as a modern IPv4 router.
417 PIM has been turned on by default in the IPv4 multicast
418 routing code. The kernel option 'PIM' has now been removed.
419 PIM is now built by default if option 'MROUTING' is specified.
420 It may now be loaded into GENERIC kernels by loading the
424 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing
425 has been removed. Its functionality may be achieved by explicitly
426 configuring gif(4) interfaces and using the 'phyint' keyword in
428 XORP does not support source-routed IPv4 multicast tunnels nor the
429 integrated IPIP tunneling, therefore it is not affected by this
430 change. The __FreeBSD_version macro has been bumped to 700030.
433 Support for PCI Message Signalled Interrupts has been
434 re-enabled in the bge driver, only for those chips which are
435 believed to support it properly. If there are any problems,
436 MSI can be disabled completely by setting the
437 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0
441 Support for PCI Message Signalled Interrupts has been
442 disabled again in the bge driver. Many revisions of the
443 hardware fail to support it properly. Support can be
444 re-enabled by removing the #define of BGE_DISABLE_MSI in
445 "src/sys/dev/bge/if_bge.c".
448 Support for PCI Message Signalled Interrupts has been added
449 to the bge driver. If there are any problems, MSI can be
450 disabled completely by setting the 'hw.pci.enable_msi' and
451 'hw.pci.enable_msix' tunables to 0 in the loader.
454 The removal of several facets of the experimental Threading
455 system from the kernel means that the proc and thread structures
456 have changed quite a bit. I suggest all kernel modules that might
457 reference these structures be recompiled.. Especially the
461 Sound infrastructure has been updated with various fixes and
462 improvements. Most of the changes are pretty much transparent,
463 with exceptions of followings:
464 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been
465 moved to their own dev sysctl nodes, for example:
466 hw.snd.pcm0.vchans -> dev.pcm.0.vchans
467 2) /dev/dspr%d.%d has been deprecated. Each channel now has its
468 own chardev in the form of "dsp%d.<function>%d", where <function>
469 is p = playback, r = record and v = virtual, respectively. Users
470 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d".
471 This does not affect those who are using "/dev/dsp".
474 geom(4)'s gmirror(8) class metadata structure has been
475 rev'd from v3 to v4. If you update across this point and
476 your metadata is converted for you, you will not be easily
477 able to downgrade since the /boot/kernel.old/geom_mirror.ko
478 kernel module will be unable to read the v4 metadata. You
479 can resolve this by doing from the loader(8) prompt:
481 set vfs.root.mountfrom="ufs:/dev/XXX"
483 where XXX is the root slice of one of the disks that composed
484 the mirror (i.e.: /dev/ad0s1a). You can then rebuild
485 the array the same way you built it originally.
488 The following binaries have been disconnected from the build:
489 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs,
490 and mount_std. The functionality of these programs has been
491 moved into the mount program. For example, to mount a devfs
492 filesystem, instead of using mount_devfs, use: "mount -t devfs".
493 This does not affect entries in /etc/fstab, since entries in
494 /etc/fstab are always processed with "mount -t fstype".
497 Support for PCI Message Signalled Interrupts on i386 and amd64
498 has been added to the kernel and various drivers will soon be
499 updated to use MSI when it is available. If there are any problems,
500 MSI can be disabled completely by setting the 'hw.pci.enable_msi'
501 and 'hw.pci.enable_msix' tunables to 0 in the loader.
504 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING.
505 The lockmgr object layout has been changed as a result of having
506 a lock_object embedded in it. As a consequence all file system
507 kernel modules must be re-compiled. The mutex profiling man page
508 has not yet been updated to reflect this change.
511 KSE in the kernel has now been made optional and turned on by
512 default. Use 'nooption KSE' in your kernel config to turn it
513 off. All kernel modules *must* be recompiled after this change.
514 There-after, modules from a KSE kernel should be compatible with
515 modules from a NOKSE kernel due to the temporary padding fields
516 added to 'struct proc'.
519 mrouted and its utilities have been removed from the base system.
522 Some ioctl(2) command codes have changed. Full backward ABI
523 compatibility is provided if the "options COMPAT_FREEBSD6" is
524 present in the kernel configuration file. Make sure to add
525 this option to your kernel config file, or recompile X.Org
526 and the rest of ports; otherwise they may refuse to work.
529 tcpslice has been removed from the base system.
532 The sizes of struct tcpcb (and struct xtcpcb) have changed due to
533 the rewrite of TCP syncookies. Tools like netstat, sockstat, and
534 systat needs to be rebuilt.
537 libpcap updated to v0.9.4 and tcpdump to v3.9.4
540 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
541 for IPFIREWALL_FORWARD is now as it was before when it was first
542 committed and for years after. The behaviour is now ON.
545 enigma(1)/crypt(1) utility has been changed on 64 bit architectures.
546 Now it can decrypt files created from different architectures.
547 Unfortunately, it is no longer able to decrypt a cipher text
548 generated with an older version on 64 bit architectures.
549 If you have such a file, you need old utility to decrypt it.
552 The interface version of the i4b kernel part has changed. So
553 after updating the kernel sources and compiling a new kernel,
554 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
555 be rebuilt, and vice versa.
558 The XBOX kernel now defaults to the nfe(4) driver instead of
559 the nve(4) driver. Please update your configuration
563 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx
564 PCnet family of NICs has been removed. The new le(4) driver serves
565 as an equivalent but cross-platform replacement with the pcn(4)
566 driver still providing performance-optimized support for the subset
567 of AMD Am79C971 PCnet-FAST and greater chips as before.
570 The machdep.* sysctls and the adjkerntz utility have been
571 modified a bit. The new adjkerntz utility uses the new
572 sysctl names and sysctlbyname() calls, so it may be impossible
573 to run an old /sbin/adjkerntz utility in single-user mode
574 with a new kernel. Replace the `adjkerntz -i' step before
575 `make installworld' with:
577 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i
579 and proceed as usual with the rest of the installworld-stage
580 steps. Otherwise, you risk installing binaries with their
581 timestamp set several hours in the future, especially if
582 you are running with local time set to GMT+X hours.
585 The ip6fw utility has been removed. The behavior provided by
586 ip6fw has been in ipfw2 for a good while and the rc.d scripts
587 have been updated to deal with it. There are some rules that
588 might not migrate cleanly. Use rc.firewall6 as a template to
592 The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
593 attachments have been removed. Make sure to configure scc(4)
594 on sparc64. Note also that by default puc(4) will use uart(4)
595 and not sio(4) for serial ports because interrupt handling has
596 been optimized for multi-port serial cards and only uart(4)
597 implements the interface to support it.
600 The scc(4) driver replaces puc(4) for Serial Communications
601 Controllers (SCCs) like the Siemens SAB82532 and the Zilog
602 Z8530. On sparc64, it is advised to add scc(4) to the kernel
603 configuration to make sure that the serial ports remain
607 Most world/kernel related NO_* build options changed names.
608 New knobs have common prefixes WITHOUT_*/WITH_* (modelled
609 after FreeBSD ports) and should be set in /etc/src.conf
610 (the src.conf(5) manpage is provided). Full backwards
611 compatibility is maintained for the time being though it's
612 highly recommended to start moving old options out of the
613 system-wide /etc/make.conf file into the new /etc/src.conf
614 while also properly renaming them. More conversions will
615 likely follow. Posting to current@:
617 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html
620 The NETSMBCRYPTO kernel option has been retired because its
621 functionality is always included in NETSMB and smbfs.ko now.
624 The TDFX_LINUX kernel option was retired and replaced by the
625 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko
626 kernel module. Loading it alone should suffice to get 3dfx support
627 for Linux apps because it will pull in 3dfx.ko and linux.ko through
631 The 'audit' group was added to support the new auditing functionality
632 in the base system. Be sure to follow the directions for updating,
633 including the requirement to run mergemaster -p.
636 The kernel ABI to file system modules was changed on i386.
637 Please make sure that your kernel and modules are in sync.
640 This actually occured some time ago, but installing the kernel
641 now also installs a bunch of symbol files for the kernel modules.
642 This increases the size of /boot/kernel to about 67Mbytes. You
643 will need twice this if you will eventually back this up to kernel.old
644 on your next install.
645 If you have a shortage of room in your root partition, you should add
646 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes"
647 to your /etc/make.conf.
650 libc's malloc implementation has been replaced. This change has the
651 potential to uncover application bugs that previously went unnoticed.
652 See the malloc(3) manual page for more details.
655 The generic netgraph(4) cookie has been changed. If you upgrade
656 kernel passing this point, you also need to upgrade userland
657 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4.
660 si(4)'s device files now contain the unit number.
661 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
664 The kernel ABI was mostly destroyed due to a change in the size
665 of struct lock_object which is nested in other structures such
666 as mutexes which are nested in all sorts of other structures.
667 Make sure your kernel and modules are in sync.
670 The page coloring algorithm in the VM subsystem was converted
671 from tuning with kernel options to autotuning. Please remove
672 any PQ_* option except PQ_NOOPT from your kernel config.
675 The net80211-related tools in the tools/tools/ath directory
676 have been moved to tools/tools/net80211 and renamed with a
677 "wlan" prefix. Scripts that use them should be adjusted
681 Scripts in the local_startup directories (as defined in
682 /etc/defaults/rc.conf) that have the new rc.d semantics will
683 now be run as part of the base system rcorder. If there are
684 errors or problems with one of these local scripts, it could
685 cause boot problems. If you encounter such problems, boot in
686 single user mode, remove that script from the */rc.d directory.
687 Please report the problem to the port's maintainer, and the
688 freebsd-ports@freebsd.org mailing list.
691 The nodev mount option was deprecated in RELENG_6 (where it
692 was a no-op), and is now unsupported. If you have nodev or dev listed
693 in /etc/fstab, remove it, otherwise it will result in a mount error.
696 ABI between ipfw(4) and ipfw(8) has been changed. You need
697 to rebuild ipfw(8) when rebuilding kernel.
700 rp(4)'s device files now contain the unit number.
701 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
704 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
705 Its /etc/rc.conf.d configuration file has been `ppp' from
706 the beginning, and hence there is no need to touch it.
709 Now most modules get their build-time options from the kernel
710 configuration file. A few modules still have fixed options
711 due to their non-conformant implementation, but they will be
712 corrected eventually. You may need to review the options of
713 the modules in use, explicitly specify the non-default options
714 in the kernel configuration file, and rebuild the kernel and
718 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
719 to turn polling(4) on your interfaces.
722 The old bridge(4) implementation was retired. The new
723 if_bridge(4) serves as a full functional replacement.
726 The ai_addrlen of a struct addrinfo was changed to a socklen_t
727 to conform to POSIX-2001. This change broke an ABI
728 compatibility on 64 bit architecture. You have to recompile
729 userland programs that use getaddrinfo(3) on 64 bit
733 RELENG_6 branched here.
736 The pccard_ifconfig rc.conf variable has been removed and a new
737 variable, ifconfig_DEFAULT has been introduced. Unlike
738 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
739 do not have ifconfig_ifn entries rather than just those in
740 removable_interfaces.
743 Some previous versions of PAM have permitted the use of
744 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
745 to third party PAM modules in /usr/local/lib. A change has been
746 made to require the use of absolute paths in order to avoid
747 ambiguity and dependence on library path configuration, which may
748 affect existing configurations.
751 Major changes to network interface API. All drivers must be
752 recompiled. Drivers not in the base system will need to be
753 updated to the new APIs.
756 Changes were made to kinfo_proc in sys/user.h. Please recompile
757 userland, or commands like `fstat', `pkill', `ps', `top' and `w'
758 will not behave correctly.
760 The API and ABI for hwpmc(4) have changed with the addition
761 of sampling support. Please recompile lib/libpmc(3) and
762 usr.sbin/{pmcstat,pmccontrol}.
765 The OpenBSD dhclient was imported in place of the ISC dhclient
766 and the network interface configuration scripts were updated
767 accordingly. If you use DHCP to configure your interfaces, you
768 must now run devd. Also, DNS updating was lost so you will need
769 to find a workaround if you use this feature.
771 The '_dhcp' user was added to support the OpenBSD dhclient. Be
772 sure to run mergemaster -p (like you are supposed to do every time
776 if_bridge was added to the tree. This has changed struct ifnet.
777 Please recompile userland and all network related modules.
780 The n_net of a struct netent was changed to an uint32_t, and
781 1st argument of getnetbyaddr() was changed to an uint32_t, to
782 conform to POSIX-2001. These changes broke an ABI
783 compatibility on 64 bit architecture. With these changes,
784 shlib major of libpcap was bumped. You have to recompile
785 userland programs that use getnetbyaddr(3), getnetbyname(3),
786 getnetent(3) and/or libpcap on 64 bit architecture.
789 Kernel parsing of extra options on '#!' first lines of shell
790 scripts has changed. Lines with multiple options likely will
791 fail after this date. For full details, please see
792 http://people.freebsd.org/~gad/Updating-20050528.txt
795 The packet filter (pf) code has been updated to OpenBSD 3.7
796 Please note the changed anchor syntax and the fact that
797 authpf(8) now needs a mounted fdescfs(5) to function.
800 The NO_MIXED_MODE kernel option has been removed from the i386
801 amd64 platforms as its use has been superceded by the new local
802 APIC timer code. Any kernel config files containing this option
806 The on-disk format of LC_CTYPE files was changed to be machine
807 independent. Please make sure NOT to use NO_CLEAN buildworld
808 when crossing this point. Crossing this point also requires
809 recompile or reinstall of all locale depended packages.
812 The ifi_epoch member of struct if_data has been changed to
813 contain the uptime at which the interface was created or the
814 statistics zeroed rather then the wall clock time because
815 wallclock time may go backwards. This should have no impact
816 unless an snmp implementation is using this value (I know of
820 The acpi_perf and acpi_throttle drivers are now part of the
821 acpi(4) main module. They are no longer built separately.
824 The layout of struct image_params has changed. You have to
825 recompile all compatibility modules (linux, svr4, etc) for use
829 The p4tcc driver has been merged into cpufreq(4). This makes
830 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
831 compile in "device cpufreq" to restore this functionality.
834 The responsibility of recomputing the file system summary of
835 a SoftUpdates-enabled dirty volume has been transferred to the
836 background fsck. A rebuild of fsck(8) utility is recommended
837 if you have updated the kernel.
839 To get the old behavior (recompute file system summary at mount
840 time), you can set vfs.ffs.compute_summary_at_mount=1 before
841 mounting the new volume.
844 The cpufreq import is complete. As part of this, the sysctls for
845 acpi(4) throttling have been removed. The power_profile script
846 has been updated, so you can use performance/economy_cpu_freq in
847 rc.conf(5) to set AC on/offline cpu frequencies.
850 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
851 requires recompiling libnetgraph and userland netgraph utilities.
854 Support for abbreviated forms of a number of ipfw options is
855 now deprecated. Warnings are printed to stderr indicating the
856 correct full form when a match occurs. Some abbreviations may
857 be supported at a later date based on user feedback. To be
858 considered for support, abbreviations must be in use prior to
859 this commit and unlikely to be confused with current key words.
862 By a popular demand, a lot of NOFOO options were renamed
863 to NO_FOO (see bsd.compat.mk for a full list). The old
864 spellings are still supported, but will cause annoying
865 warnings on stderr. Make sure you upgrade properly (see
866 the COMMON ITEMS: section later in this file).
869 Auto-loading of ancillary wlan modules such as wlan_wep has
870 been temporarily disabled; you need to statically configure
871 the modules you need into your kernel or explicitly load them
872 prior to use. Specifically, if you intend to use WEP encryption
873 with an 802.11 device load/configure wlan_wep; if you want to
874 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
875 and wlan_xauth as required.
878 The behaviour of ppp(8) has changed slightly. If lqr is enabled
879 (``enable lqr''), older versions would revert to LCP ECHO mode on
880 negotiation failure. Now, ``enable echo'' is required for this
881 behaviour. The ppp version number has been bumped to 3.4.2 to
885 The wlan support has been updated to split the crypto support
886 into separate modules. For static WEP you must configure the
887 wlan_wep module in your system or build and install the module
888 in place where it can be loaded (the kernel will auto-load
889 the module when a wep key is configured).
892 The ath driver has been updated to split the tx rate control
893 algorithm into a separate module. You need to include either
894 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
897 Support for systems with an 80386 CPU has been removed. Please
898 use FreeBSD 5.x or earlier on systems with an 80386.
901 We have had a hack which would mount the root filesystem
902 R/W if the device were named 'md*'. As part of the vnode
903 work I'm doing I have had to remove this hack. People
904 building systems which use preloaded MD root filesystems
905 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
906 their /etc/rc scripts.
909 FreeBSD 5.3 shipped here.
912 The size of struct tcpcb has changed again due to the removal
913 of RFC1644 T/TCP. You have to recompile userland programs that
914 read kmem for tcp sockets directly (netstat, sockstat, etc.)
917 The size of struct tcpcb has changed. You have to recompile
918 userland programs that read kmem for tcp sockets directly
919 (netstat, sockstat, etc.)
922 RELENG_5 branched here. For older entries, please see updating
923 in the RELENG_5 branch.
929 Avoid using make -j when upgrading. From time to time in the
930 past there have been problems using -j with buildworld and/or
931 installworld. This is especially true when upgrading between
932 "distant" versions (eg one that cross a major release boundary
933 or several minor releases, or when several months have passed
934 on the -current branch).
936 Sometimes, obscure build problems are the result of environment
937 poisoning. This can happen because the make utility reads its
938 environment when searching for values for global variables.
939 To run your build attempts in an "environmental clean room",
940 prefix all make commands with 'env -i '. See the env(1) manual
941 page for more details.
943 When upgrading from one major version to another it is generally
944 best to upgrade to the latest code in the currently installed branch
945 first, then do an upgrade to the new branch. This is the best-tested
946 upgrade path, and has the highest probability of being successful.
947 Please try this approach before reporting problems with a major
952 If you are updating from a prior version of FreeBSD (even one just
953 a few days old), you should follow this procedure. It is the most
954 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
956 make kernel-toolchain
957 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
958 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
960 To test a kernel once
961 ---------------------
962 If you just want to boot a kernel once (because you are not sure
963 if it works, or if you want to boot a known bad kernel to provide
964 debugging information) run
965 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
966 nextboot -k testkernel
968 To just build a kernel when you know that it won't mess you up
969 --------------------------------------------------------------
970 This assumes you are already running a 5.X system. Replace
971 ${arch} with the architecture of your machine (e.g. "i386",
972 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
974 cd src/sys/${arch}/conf
975 config KERNEL_NAME_HERE
976 cd ../compile/KERNEL_NAME_HERE
981 If this fails, go to the "To build a kernel" section.
983 To rebuild everything and install it on the current system.
984 -----------------------------------------------------------
985 # Note: sometimes if you are running current you gotta do more than
986 # is listed here if you are upgrading from a really old current.
988 <make sure you have good level 0 dumps>
990 make kernel KERNCONF=YOUR_KERNEL_HERE
992 <reboot in single user> [3]
1000 To cross-install current onto a separate partition
1001 --------------------------------------------------
1002 # In this approach we use a separate partition to hold
1003 # current's root, 'usr', and 'var' directories. A partition
1004 # holding "/", "/usr" and "/var" should be about 2GB in
1007 <make sure you have good level 0 dumps>
1010 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1011 <maybe newfs current's root partition>
1012 <mount current's root partition on directory ${CURRENT_ROOT}>
1013 make installworld DESTDIR=${CURRENT_ROOT}
1014 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1015 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1016 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
1017 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1018 <reboot into current>
1019 <do a "native" rebuild/install as described in the previous section>
1020 <maybe install compatibility libraries from src/lib/compat>
1024 To upgrade in-place from 5.x-stable to current
1025 ----------------------------------------------
1026 <make sure you have good level 0 dumps>
1028 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
1030 <reboot in single user> [3]
1037 Make sure that you've read the UPDATING file to understand the
1038 tweaks to various things you need. At this point in the life
1039 cycle of current, things change often and you are on your own
1040 to cope. The defaults can also change, so please read ALL of
1041 the UPDATING entries.
1043 Also, if you are tracking -current, you must be subscribed to
1044 freebsd-current@freebsd.org. Make sure that before you update
1045 your sources that you have read and understood all the recent
1046 messages there. If in doubt, please track -stable which has
1047 much fewer pitfalls.
1049 [1] If you have third party modules, such as vmware, you
1050 should disable them at this point so they don't crash your
1053 [3] From the bootblocks, boot -s, and then do
1058 adjkerntz -i # if CMOS is wall time
1059 Also, when doing a major release upgrade, it is required that
1060 you boot into single user mode to do the installworld.
1062 [4] Note: This step is non-optional. Failure to do this step
1063 can result in a significant reduction in the functionality of the
1064 system. Attempting to do it by hand is not recommended and those
1065 that pursue this avenue should read this file carefully, as well
1066 as the archives of freebsd-current and freebsd-hackers mailing lists
1067 for potential gotchas.
1069 [5] Usually this step is a noop. However, from time to time
1070 you may need to do this if you get unknown user in the following
1071 step. It never hurts to do it all the time. You may need to
1072 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1073 install) after the buildworld before this step if you last updated
1074 from current before 20020224 or from -stable before 20020408.
1076 [8] In order to have a kernel that can run the 4.x binaries
1077 needed to do an installworld, you must include the COMPAT_FREEBSD4
1078 option in your kernel. Failure to do so may leave you with a system
1079 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
1080 is required to run the 5.x binaries on more recent kernels.
1082 Make sure that you merge any new devices from GENERIC since the
1083 last time you updated your kernel config file.
1085 [9] When checking out sources, you must include the -P flag to have
1086 cvs prune empty directories.
1088 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1089 "?=" instead of the "=" assignment operator, so that buildworld can
1090 override the CPUTYPE if it needs to.
1092 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1093 not on the command line, or in /etc/make.conf. buildworld will
1094 warn if it is improperly defined.
1097 This file contains a list, in reverse chronological order, of major
1098 breakages in tracking -current. Not all things will be listed here,
1099 and it only starts on October 16, 2004. Updating files can found in
1100 previous releases if your system is older than this.
