11 20090624: p2 FreeBSD-EN-09:02.bce, FreeBSD-EN-09:03.fxp,
13 Fix packet length calculation in bce(4). [EN-09:02]
15 Correctly set IP packet length for TSO in fxp(4). [EN-09:03]
17 Fix a lock order reversal bug that could cause deadlock during
20 20090610: p1 FreeBSD-SA-09:09.pipe, FreeBSD-SA-09:10.ipv6,
22 Prevent integer overflow in direct pipe write code from circumventing
23 virtual-to-physical page lookups. [09:09]
25 Add missing permissions check for SIOCSIFINFO_IN6 ioctl. [09:10]
27 Fix buffer overflow in "autokey" negotiation in ntpd(8). [09:11]
32 20090422: FreeBSD-SA-09:07.libc, FreeBSD-SA-09:08.openssl
33 Don't leak information via uninitialized space in db(3) records.
36 Sanity-check string lengths in order to stop OpenSSL crashing
37 when printing corrupt BMPString or UniversalString objects. [09:08]
40 Following bug-fixes to TCP connection state flags, netstat, systat,
41 and sockstat will need to be rebuilt in order to properly print
42 connections in the TIMEWAIT state.
45 Change IPv6 ephemeral port allocation from sequential to
46 random allocation, like IPv4 has done for more than four years.
47 The implementation shares infrastructure with IPv4. This
48 means that there is only one set of sysctls to control both
49 IPv4 and IPv6. See ip(4) man page for details.
52 A workaround is committed to allow the creation of System V shared
53 memory segment of size > 2 GB on the 64-bit architectures.
54 Due to a limitation of the existing ABI, the shm_segsz member
55 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is
56 wrong for large segments. Note that limits must be explicitely
57 raised to allow such segments to be created.
59 The management interface that is used by ipcs(1) has to be changed
60 in incompatible way. Rebuild the ipcs(1) utility with the new
61 headers after the update. Buildworld/installworld takes care
62 of this issue automatically.
65 The open-source Atheros HAL has been merged from HEAD
67 The kernel compile-time option AH_SUPPORT_AR5416 has been
68 added to support certain newer Atheros parts, particularly
70 The following modules are no longer available, and should be
71 removed from MODULES_OVERRIDE and/or loader.conf:-
72 ath_hal ath_rate_amrr ath_rate_onoe ath_rate_sample
75 ZFS users on amd64 machines with 4GB or more of RAM should
76 reevaluate their need for setting vm.kmem_size_max and
77 vm.kmem_size manually. In fact, after recent changes to the
78 kernel, the default value of vm.kmem_size is larger than the
79 suggested manual setting in most ZFS/FreeBSD tuning guides.
82 Multi-IPv4/v6/no-IP jail support was merged to STABLE.
83 You need to rebuild jls(8) and to use the new features
84 jail(8), jexec(8) and cpuset(1) with a new kernel.
85 __FreeBSD_version was bumped to 701103.
88 NTFS has been removed from GENERIC kernel on amd64 to match
89 GENERIC on i386. Should not cause any issues since mount_ntfs(8)
90 will load ntfs.ko module automatically when NTFS support is
91 actually needed, unless ntfs.ko is not installed or security
92 level prohibits loading kernel modules. If either is the case,
93 "options NTFS" has to be added into kernel config.
96 powerd(8) was updated to get better SMP support.
97 Meanings of the -i and -r command line options were changed.
100 snd_hda(4) driver was updated to version 20081226_0122.
102 Due to added HDMI audio and logical audio devices support, updated
103 driver often provides several PCM devices. In some cases it can make
104 system default audio device no longer correspond to the users's
105 habbitual audio connectors. In such cases wanted device can be
106 specified in audio application setup or defined globally via
107 hw.snd.default_unit sysctl according to sound(4) and snd_hda(4)
114 ntpd has been upgraded to 4.2.4p5.
117 OpenSSH has been upgraded to 5.1p1.
120 DTrace support was merged to STABLE today. In the best
121 tradition of "the dog ate my homework", subversion decided
122 that the commit message was too large and opted not to send
123 it. It was a stealth commit!
125 A 'make buildkernel' will now default to build the kernel
126 and modules with both DTrace kernel hooks and CTF data ready
129 After you have installed both world and the kernel, and
130 rebooted, you can 'kldload dtraceall' to load all the DTrace
131 kernel modules and then you're set to run the 'dtrace'
134 For DTrace documentation, refer to:
135 <http://wikis.sun.com/display/DTrace/Documentation>
137 We are limited to kernel tracing at the moment, so the pid
138 provider is not available.
140 For the syscall provider, note that the arguments to the
141 return probes are the same as for the entry probes.
144 Today STABLE got a reorganization of the Intel E1000
145 driver code. In order to better support our new adapters
146 there is a new driver, igb, that is now to be used for
147 either the 82575 or 82576 adapters. The source however,
148 is all now in sys/dev/e1000, both em and igb drivers are
149 built from that common directory if you configure them
150 in the kernel. Making loadable drivers still happens in
151 the same place: sys/modules/[em, igb].
153 The important thing to note is that the 82575 adapters
154 were supported in the em driver in 7.0, but now needed
155 to be moved into igb, so if you have the effected cards
156 be sure and make any script changes to follow the name
159 There are only 3 PCI ID's effected in this change:
160 0x10A7, 0x10A9, and 0x10D6
161 So you can know ahead of time if they will be effected,
162 these will now be supported in the igb driver. That
163 driver will also support the new 82576 followon.
165 The driver reorg in STABLE is inconvenient but it really
166 was necessary for Intel to do this, and I figured it was
167 better to have this small admin type issue than not to
168 have support for this new hardware for a whole release
172 I have MFC'd in code to support multiple routing tables.
173 see the man pages setfib(1) and setfib(2).
174 This is a backwards compatible version,
175 but to make use of it you need to compile your kernel
176 with options ROUTETABLES=2 (or more up to 16).
182 Note the addition of m_collapse for compacting mbuf chains.
185 The AT keyboard emulation of sunkbd(4) has been turned on
186 by default. In order to make the special symbols of the Sun
187 keyboards driven by sunkbd(4) work under X these now have
188 to be configured the same way as Sun USB keyboards driven
189 by ukbd(4) (which also does AT keyboard emulation), f.e.:
191 Option "XkbLayout" "us"
192 Option "XkbRules" "xorg"
193 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us"
196 It has been decided that it is desirable to provide ABI
197 backwards compatibility to the FreeBSD 4/5/6 versions of the
198 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was
199 broken with the introduction of PCI domain support (see the
200 20070930 entry). Unfortunately, this required the ABI of
201 PCIOCGETCONF to be broken again in order to be able to
202 provide backwards compatibility to the old version of that
203 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled
204 again. As for prominent ports this affects neither pciutils
205 nor xorg-server this time, the hal port needs to be rebuilt
212 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and
213 WITHOUT_LIBTHR are set.
216 The PCI code has been made aware of PCI domains. This means that
217 the location strings as used by pciconf(8) etc are now in the
218 following format: pci<domain>:<bus>:<device>[:<function>]. It
219 also means that consumers of <sys/pciio.h> potentially need to
220 be recompiled; this includes the hal and xorg-server ports.
223 The caching daemon (cached) was renamed to nscd. nscd.conf
224 configuration file should be used instead of cached.conf and
225 nscd_enable, nscd_pidfile and nscd_flags options should be used
226 instead of cached_enable, cached_pidfile and cached_flags in
230 The new IPsec code is now compiled in using the IPSEC option. The
231 IPSEC option now requires "device crypto" be defined in your kernel
232 configuration. The FAST_IPSEC kernel option is now deprecated.
235 The packet filter (pf) code has been updated to OpenBSD 4.1 Please
236 note the changed syntax - keep state is now on by default. Also
237 note the fact that ftp-proxy(8) has been changed from bottom up and
238 has been moved from libexec to usr/sbin. Changes in the ALTQ
239 handling also affect users of IPFW's ALTQ capabilities.
242 Remove KAME IPsec in favor of FAST_IPSEC, which is now the
243 only IPsec supported by FreeBSD. The new IPsec stack
244 supports both IPv4 and IPv6. The kernel option will change
245 after the code changes have settled in. For now the kernel
246 option IPSEC is deprecated and FAST_IPSEC is the only option, that
247 will change after some settling time.
250 The wicontrol(8) utility has been removed from the base system. wi(4)
251 cards should be configured using ifconfig(8), see the man page for more
255 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver
256 instead of the nve(4) driver. Please update your configuration
260 By default, /etc/rc.d/sendmail no longer rebuilds the aliases
261 database if it is missing or older than the aliases file. If
262 desired, set the new rc.conf option sendmail_rebuild_aliases
263 to "YES" to restore that functionality.
266 The IPv4 multicast socket code has been considerably modified, and
267 moved to the file sys/netinet/in_mcast.c. Initial support for the
268 RFC 3678 Source-Specific Multicast Socket API has been added to
269 the IPv4 network stack.
271 Strict multicast and broadcast reception is now the default for
272 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable
273 has now been removed.
275 The RFC 1724 hack for interface selection has been removed; the use
276 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has
277 been added to replace it. Consumers such as routed will soon be
278 updated to reflect this.
280 These changes affect users who are running routed(8) or rdisc(8)
281 from the FreeBSD base system on point-to-point or unnumbered
285 The net80211 layer has changed significantly and all wireless
286 drivers that depend on it need to be recompiled. Further these
287 changes require that any program that interacts with the wireless
288 support in the kernel be recompiled; this includes: ifconfig,
289 wpa_supplicant, hostapd, and wlanstats. Users must also, for
290 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules
291 if they use modules for wireless support. These modules implement
292 scanning support for station and ap modes, respectively. Failure
293 to load the appropriate module before marking a wireless interface
294 up will result in a message to the console and the device not
298 The pam_nologin(8) module ceases to provide an authentication
299 function and starts providing an account management function.
300 Consequent changes to /etc/pam.d should be brought in using
301 mergemaster(8). Third-party files in /usr/local/etc/pam.d may
302 need manual editing as follows. Locate this line (or similar):
304 auth required pam_nologin.so no_warn
306 and change it according to this example:
308 account required pam_nologin.so no_warn
310 That is, the first word needs to be changed from "auth" to
311 "account". The new line can be moved to the account section
312 within the file for clarity. Not updating pam.conf(5) files
313 will result in nologin(5) ignored by the respective services.
316 The ether_ioctl() function has been synchronized with ioctl(2)
317 and ifnet.if_ioctl. Due to that, the size of one of its arguments
318 has changed on 64-bit architectures. All kernel modules using
319 ether_ioctl() need to be rebuilt on such architectures.
322 Improved INCLUDE_CONFIG_FILE support has been introduced to the
323 config(8) utility. In order to take advantage of this new
324 functionality, you are expected to recompile and install
325 src/usr.sbin/config. If you don't rebuild config(8), and your
326 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel
327 build will be broken because of a missing "kernconfstring"
331 Symbol versioning is enabled by default. To disable it, use
332 option WITHOUT_SYMVER. It is not advisable to attempt to
333 disable symbol versioning once it is enabled; your installworld
334 will break because a symbol version-less libc will get installed
335 before the install tools. As a result, the old install tools,
336 which previously had symbol dependencies to FBSD_1.0, will fail
337 because the freshly installed libc will not have them.
339 The default threading library (providing "libpthread") has been
340 changed to libthr. If you wish to have libkse as your default,
341 use option DEFAULT_THREAD_LIB=libkse for the buildworld.
344 The ABI breakage in sendmail(8)'s libmilter has been repaired
345 so it is no longer necessary to recompile mail filters (aka,
346 milters). If you recompiled mail filters after the 20070408
347 note, it is not necessary to recompile them again.
350 The new trunk(4) driver has been renamed to lagg(4) as it better
351 reflects its purpose. ifconfig will need to be recompiled.
354 sendmail(8) has been updated to version 8.14.1. Mail filters
355 (aka, milters) compiled against the libmilter included in the
356 base operating system should be recompiled.
359 Firmwares for ipw(4) and iwi(4) are now included in the base tree.
360 In order to use them one must agree to the respective LICENSE in
361 share/doc/legal and define legal.intel_<name>.license_ack=1 via
362 loader.conf(5) or kenv(1). Make sure to deinstall the now
363 deprecated modules from the respective firmware ports.
366 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3)
367 were removed from FreeBSD's libc. These originally came from INRIA
368 IPv6. Nothing in FreeBSD ever used them. They may be regarded as
369 deprecated in previous releases.
370 The AF_LINK support for getnameinfo(3) was merged from NetBSD to
371 replace it as a more portable (and re-entrant) API.
374 To support interrupt filtering a modification to the newbus API
375 has occurred, ABI was broken and __FreeBSD_version was bumped
376 to 700031. Please make sure that your kernel and modules are in
378 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941
381 The IPv6 multicast forwarding code may now be loaded into GENERIC
382 kernels by loading the ip_mroute.ko module. This is built into the
383 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are
384 set; see src.conf(5) for more information.
387 The output of netstat -r has changed. Without -n, we now only
388 print a "network name" without the prefix length if the network
389 address and mask exactly match a Class A/B/C network, and an entry
390 exists in the nsswitch "networks" map.
391 With -n, we print the full unabbreviated CIDR network prefix in
392 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default".
393 This change is in preparation for changes such as equal-cost
394 multipath, and to more generally assist operational deployment
395 of FreeBSD as a modern IPv4 router.
398 PIM has been turned on by default in the IPv4 multicast
399 routing code. The kernel option 'PIM' has now been removed.
400 PIM is now built by default if option 'MROUTING' is specified.
401 It may now be loaded into GENERIC kernels by loading the
405 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing
406 has been removed. Its functionality may be achieved by explicitly
407 configuring gif(4) interfaces and using the 'phyint' keyword in
409 XORP does not support source-routed IPv4 multicast tunnels nor the
410 integrated IPIP tunneling, therefore it is not affected by this
411 change. The __FreeBSD_version macro has been bumped to 700030.
414 Support for PCI Message Signalled Interrupts has been
415 re-enabled in the bge driver, only for those chips which are
416 believed to support it properly. If there are any problems,
417 MSI can be disabled completely by setting the
418 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0
422 Support for PCI Message Signalled Interrupts has been
423 disabled again in the bge driver. Many revisions of the
424 hardware fail to support it properly. Support can be
425 re-enabled by removing the #define of BGE_DISABLE_MSI in
426 "src/sys/dev/bge/if_bge.c".
429 Support for PCI Message Signalled Interrupts has been added
430 to the bge driver. If there are any problems, MSI can be
431 disabled completely by setting the 'hw.pci.enable_msi' and
432 'hw.pci.enable_msix' tunables to 0 in the loader.
435 The removal of several facets of the experimental Threading
436 system from the kernel means that the proc and thread structures
437 have changed quite a bit. I suggest all kernel modules that might
438 reference these structures be recompiled.. Especially the
442 Sound infrastructure has been updated with various fixes and
443 improvements. Most of the changes are pretty much transparent,
444 with exceptions of followings:
445 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been
446 moved to their own dev sysctl nodes, for example:
447 hw.snd.pcm0.vchans -> dev.pcm.0.vchans
448 2) /dev/dspr%d.%d has been deprecated. Each channel now has its
449 own chardev in the form of "dsp%d.<function>%d", where <function>
450 is p = playback, r = record and v = virtual, respectively. Users
451 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d".
452 This does not affect those who are using "/dev/dsp".
455 geom(4)'s gmirror(8) class metadata structure has been
456 rev'd from v3 to v4. If you update across this point and
457 your metadata is converted for you, you will not be easily
458 able to downgrade since the /boot/kernel.old/geom_mirror.ko
459 kernel module will be unable to read the v4 metadata. You
460 can resolve this by doing from the loader(8) prompt:
462 set vfs.root.mountfrom="ufs:/dev/XXX"
464 where XXX is the root slice of one of the disks that composed
465 the mirror (i.e.: /dev/ad0s1a). You can then rebuild
466 the array the same way you built it originally.
469 The following binaries have been disconnected from the build:
470 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs,
471 and mount_std. The functionality of these programs has been
472 moved into the mount program. For example, to mount a devfs
473 filesystem, instead of using mount_devfs, use: "mount -t devfs".
474 This does not affect entries in /etc/fstab, since entries in
475 /etc/fstab are always processed with "mount -t fstype".
478 Support for PCI Message Signalled Interrupts on i386 and amd64
479 has been added to the kernel and various drivers will soon be
480 updated to use MSI when it is available. If there are any problems,
481 MSI can be disabled completely by setting the 'hw.pci.enable_msi'
482 and 'hw.pci.enable_msix' tunables to 0 in the loader.
485 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING.
486 The lockmgr object layout has been changed as a result of having
487 a lock_object embedded in it. As a consequence all file system
488 kernel modules must be re-compiled. The mutex profiling man page
489 has not yet been updated to reflect this change.
492 KSE in the kernel has now been made optional and turned on by
493 default. Use 'nooption KSE' in your kernel config to turn it
494 off. All kernel modules *must* be recompiled after this change.
495 There-after, modules from a KSE kernel should be compatible with
496 modules from a NOKSE kernel due to the temporary padding fields
497 added to 'struct proc'.
500 mrouted and its utilities have been removed from the base system.
503 Some ioctl(2) command codes have changed. Full backward ABI
504 compatibility is provided if the "options COMPAT_FREEBSD6" is
505 present in the kernel configuration file. Make sure to add
506 this option to your kernel config file, or recompile X.Org
507 and the rest of ports; otherwise they may refuse to work.
510 tcpslice has been removed from the base system.
513 The sizes of struct tcpcb (and struct xtcpcb) have changed due to
514 the rewrite of TCP syncookies. Tools like netstat, sockstat, and
515 systat needs to be rebuilt.
518 libpcap updated to v0.9.4 and tcpdump to v3.9.4
521 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
522 for IPFIREWALL_FORWARD is now as it was before when it was first
523 committed and for years after. The behaviour is now ON.
526 enigma(1)/crypt(1) utility has been changed on 64 bit architectures.
527 Now it can decrypt files created from different architectures.
528 Unfortunately, it is no longer able to decrypt a cipher text
529 generated with an older version on 64 bit architectures.
530 If you have such a file, you need old utility to decrypt it.
533 The interface version of the i4b kernel part has changed. So
534 after updating the kernel sources and compiling a new kernel,
535 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
536 be rebuilt, and vice versa.
539 The XBOX kernel now defaults to the nfe(4) driver instead of
540 the nve(4) driver. Please update your configuration
544 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx
545 PCnet family of NICs has been removed. The new le(4) driver serves
546 as an equivalent but cross-platform replacement with the pcn(4)
547 driver still providing performance-optimized support for the subset
548 of AMD Am79C971 PCnet-FAST and greater chips as before.
551 The machdep.* sysctls and the adjkerntz utility have been
552 modified a bit. The new adjkerntz utility uses the new
553 sysctl names and sysctlbyname() calls, so it may be impossible
554 to run an old /sbin/adjkerntz utility in single-user mode
555 with a new kernel. Replace the `adjkerntz -i' step before
556 `make installworld' with:
558 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i
560 and proceed as usual with the rest of the installworld-stage
561 steps. Otherwise, you risk installing binaries with their
562 timestamp set several hours in the future, especially if
563 you are running with local time set to GMT+X hours.
566 The ip6fw utility has been removed. The behavior provided by
567 ip6fw has been in ipfw2 for a good while and the rc.d scripts
568 have been updated to deal with it. There are some rules that
569 might not migrate cleanly. Use rc.firewall6 as a template to
573 The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
574 attachments have been removed. Make sure to configure scc(4)
575 on sparc64. Note also that by default puc(4) will use uart(4)
576 and not sio(4) for serial ports because interrupt handling has
577 been optimized for multi-port serial cards and only uart(4)
578 implements the interface to support it.
581 The scc(4) driver replaces puc(4) for Serial Communications
582 Controllers (SCCs) like the Siemens SAB82532 and the Zilog
583 Z8530. On sparc64, it is advised to add scc(4) to the kernel
584 configuration to make sure that the serial ports remain
588 Most world/kernel related NO_* build options changed names.
589 New knobs have common prefixes WITHOUT_*/WITH_* (modelled
590 after FreeBSD ports) and should be set in /etc/src.conf
591 (the src.conf(5) manpage is provided). Full backwards
592 compatibility is maintained for the time being though it's
593 highly recommended to start moving old options out of the
594 system-wide /etc/make.conf file into the new /etc/src.conf
595 while also properly renaming them. More conversions will
596 likely follow. Posting to current@:
598 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html
601 The NETSMBCRYPTO kernel option has been retired because its
602 functionality is always included in NETSMB and smbfs.ko now.
605 The TDFX_LINUX kernel option was retired and replaced by the
606 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko
607 kernel module. Loading it alone should suffice to get 3dfx support
608 for Linux apps because it will pull in 3dfx.ko and linux.ko through
612 The 'audit' group was added to support the new auditing functionality
613 in the base system. Be sure to follow the directions for updating,
614 including the requirement to run mergemaster -p.
617 The kernel ABI to file system modules was changed on i386.
618 Please make sure that your kernel and modules are in sync.
621 This actually occured some time ago, but installing the kernel
622 now also installs a bunch of symbol files for the kernel modules.
623 This increases the size of /boot/kernel to about 67Mbytes. You
624 will need twice this if you will eventually back this up to kernel.old
625 on your next install.
626 If you have a shortage of room in your root partition, you should add
627 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes"
628 to your /etc/make.conf.
631 libc's malloc implementation has been replaced. This change has the
632 potential to uncover application bugs that previously went unnoticed.
633 See the malloc(3) manual page for more details.
636 The generic netgraph(4) cookie has been changed. If you upgrade
637 kernel passing this point, you also need to upgrade userland
638 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4.
641 si(4)'s device files now contain the unit number.
642 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
645 The kernel ABI was mostly destroyed due to a change in the size
646 of struct lock_object which is nested in other structures such
647 as mutexes which are nested in all sorts of other structures.
648 Make sure your kernel and modules are in sync.
651 The page coloring algorithm in the VM subsystem was converted
652 from tuning with kernel options to autotuning. Please remove
653 any PQ_* option except PQ_NOOPT from your kernel config.
656 The net80211-related tools in the tools/tools/ath directory
657 have been moved to tools/tools/net80211 and renamed with a
658 "wlan" prefix. Scripts that use them should be adjusted
662 Scripts in the local_startup directories (as defined in
663 /etc/defaults/rc.conf) that have the new rc.d semantics will
664 now be run as part of the base system rcorder. If there are
665 errors or problems with one of these local scripts, it could
666 cause boot problems. If you encounter such problems, boot in
667 single user mode, remove that script from the */rc.d directory.
668 Please report the problem to the port's maintainer, and the
669 freebsd-ports@freebsd.org mailing list.
672 The nodev mount option was deprecated in RELENG_6 (where it
673 was a no-op), and is now unsupported. If you have nodev or dev listed
674 in /etc/fstab, remove it, otherwise it will result in a mount error.
677 ABI between ipfw(4) and ipfw(8) has been changed. You need
678 to rebuild ipfw(8) when rebuilding kernel.
681 rp(4)'s device files now contain the unit number.
682 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
685 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
686 Its /etc/rc.conf.d configuration file has been `ppp' from
687 the beginning, and hence there is no need to touch it.
690 Now most modules get their build-time options from the kernel
691 configuration file. A few modules still have fixed options
692 due to their non-conformant implementation, but they will be
693 corrected eventually. You may need to review the options of
694 the modules in use, explicitly specify the non-default options
695 in the kernel configuration file, and rebuild the kernel and
699 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
700 to turn polling(4) on your interfaces.
703 The old bridge(4) implementation was retired. The new
704 if_bridge(4) serves as a full functional replacement.
707 The ai_addrlen of a struct addrinfo was changed to a socklen_t
708 to conform to POSIX-2001. This change broke an ABI
709 compatibility on 64 bit architecture. You have to recompile
710 userland programs that use getaddrinfo(3) on 64 bit
714 RELENG_6 branched here.
717 The pccard_ifconfig rc.conf variable has been removed and a new
718 variable, ifconfig_DEFAULT has been introduced. Unlike
719 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
720 do not have ifconfig_ifn entries rather than just those in
721 removable_interfaces.
724 Some previous versions of PAM have permitted the use of
725 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
726 to third party PAM modules in /usr/local/lib. A change has been
727 made to require the use of absolute paths in order to avoid
728 ambiguity and dependence on library path configuration, which may
729 affect existing configurations.
732 Major changes to network interface API. All drivers must be
733 recompiled. Drivers not in the base system will need to be
734 updated to the new APIs.
737 Changes were made to kinfo_proc in sys/user.h. Please recompile
738 userland, or commands like `fstat', `pkill', `ps', `top' and `w'
739 will not behave correctly.
741 The API and ABI for hwpmc(4) have changed with the addition
742 of sampling support. Please recompile lib/libpmc(3) and
743 usr.sbin/{pmcstat,pmccontrol}.
746 The OpenBSD dhclient was imported in place of the ISC dhclient
747 and the network interface configuration scripts were updated
748 accordingly. If you use DHCP to configure your interfaces, you
749 must now run devd. Also, DNS updating was lost so you will need
750 to find a workaround if you use this feature.
752 The '_dhcp' user was added to support the OpenBSD dhclient. Be
753 sure to run mergemaster -p (like you are supposed to do every time
757 if_bridge was added to the tree. This has changed struct ifnet.
758 Please recompile userland and all network related modules.
761 The n_net of a struct netent was changed to an uint32_t, and
762 1st argument of getnetbyaddr() was changed to an uint32_t, to
763 conform to POSIX-2001. These changes broke an ABI
764 compatibility on 64 bit architecture. With these changes,
765 shlib major of libpcap was bumped. You have to recompile
766 userland programs that use getnetbyaddr(3), getnetbyname(3),
767 getnetent(3) and/or libpcap on 64 bit architecture.
770 Kernel parsing of extra options on '#!' first lines of shell
771 scripts has changed. Lines with multiple options likely will
772 fail after this date. For full details, please see
773 http://people.freebsd.org/~gad/Updating-20050528.txt
776 The packet filter (pf) code has been updated to OpenBSD 3.7
777 Please note the changed anchor syntax and the fact that
778 authpf(8) now needs a mounted fdescfs(5) to function.
781 The NO_MIXED_MODE kernel option has been removed from the i386
782 amd64 platforms as its use has been superceded by the new local
783 APIC timer code. Any kernel config files containing this option
787 The on-disk format of LC_CTYPE files was changed to be machine
788 independent. Please make sure NOT to use NO_CLEAN buildworld
789 when crossing this point. Crossing this point also requires
790 recompile or reinstall of all locale depended packages.
793 The ifi_epoch member of struct if_data has been changed to
794 contain the uptime at which the interface was created or the
795 statistics zeroed rather then the wall clock time because
796 wallclock time may go backwards. This should have no impact
797 unless an snmp implementation is using this value (I know of
801 The acpi_perf and acpi_throttle drivers are now part of the
802 acpi(4) main module. They are no longer built separately.
805 The layout of struct image_params has changed. You have to
806 recompile all compatibility modules (linux, svr4, etc) for use
810 The p4tcc driver has been merged into cpufreq(4). This makes
811 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
812 compile in "device cpufreq" to restore this functionality.
815 The responsibility of recomputing the file system summary of
816 a SoftUpdates-enabled dirty volume has been transferred to the
817 background fsck. A rebuild of fsck(8) utility is recommended
818 if you have updated the kernel.
820 To get the old behavior (recompute file system summary at mount
821 time), you can set vfs.ffs.compute_summary_at_mount=1 before
822 mounting the new volume.
825 The cpufreq import is complete. As part of this, the sysctls for
826 acpi(4) throttling have been removed. The power_profile script
827 has been updated, so you can use performance/economy_cpu_freq in
828 rc.conf(5) to set AC on/offline cpu frequencies.
831 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
832 requires recompiling libnetgraph and userland netgraph utilities.
835 Support for abbreviated forms of a number of ipfw options is
836 now deprecated. Warnings are printed to stderr indicating the
837 correct full form when a match occurs. Some abbreviations may
838 be supported at a later date based on user feedback. To be
839 considered for support, abbreviations must be in use prior to
840 this commit and unlikely to be confused with current key words.
843 By a popular demand, a lot of NOFOO options were renamed
844 to NO_FOO (see bsd.compat.mk for a full list). The old
845 spellings are still supported, but will cause annoying
846 warnings on stderr. Make sure you upgrade properly (see
847 the COMMON ITEMS: section later in this file).
850 Auto-loading of ancillary wlan modules such as wlan_wep has
851 been temporarily disabled; you need to statically configure
852 the modules you need into your kernel or explicitly load them
853 prior to use. Specifically, if you intend to use WEP encryption
854 with an 802.11 device load/configure wlan_wep; if you want to
855 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
856 and wlan_xauth as required.
859 The behaviour of ppp(8) has changed slightly. If lqr is enabled
860 (``enable lqr''), older versions would revert to LCP ECHO mode on
861 negotiation failure. Now, ``enable echo'' is required for this
862 behaviour. The ppp version number has been bumped to 3.4.2 to
866 The wlan support has been updated to split the crypto support
867 into separate modules. For static WEP you must configure the
868 wlan_wep module in your system or build and install the module
869 in place where it can be loaded (the kernel will auto-load
870 the module when a wep key is configured).
873 The ath driver has been updated to split the tx rate control
874 algorithm into a separate module. You need to include either
875 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
878 Support for systems with an 80386 CPU has been removed. Please
879 use FreeBSD 5.x or earlier on systems with an 80386.
882 We have had a hack which would mount the root filesystem
883 R/W if the device were named 'md*'. As part of the vnode
884 work I'm doing I have had to remove this hack. People
885 building systems which use preloaded MD root filesystems
886 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
887 their /etc/rc scripts.
890 FreeBSD 5.3 shipped here.
893 The size of struct tcpcb has changed again due to the removal
894 of RFC1644 T/TCP. You have to recompile userland programs that
895 read kmem for tcp sockets directly (netstat, sockstat, etc.)
898 The size of struct tcpcb has changed. You have to recompile
899 userland programs that read kmem for tcp sockets directly
900 (netstat, sockstat, etc.)
903 RELENG_5 branched here. For older entries, please see updating
904 in the RELENG_5 branch.
910 Avoid using make -j when upgrading. From time to time in the
911 past there have been problems using -j with buildworld and/or
912 installworld. This is especially true when upgrading between
913 "distant" versions (eg one that cross a major release boundary
914 or several minor releases, or when several months have passed
915 on the -current branch).
917 Sometimes, obscure build problems are the result of environment
918 poisoning. This can happen because the make utility reads its
919 environment when searching for values for global variables.
920 To run your build attempts in an "environmental clean room",
921 prefix all make commands with 'env -i '. See the env(1) manual
922 page for more details.
924 When upgrading from one major version to another it is generally
925 best to upgrade to the latest code in the currently installed branch
926 first, then do an upgrade to the new branch. This is the best-tested
927 upgrade path, and has the highest probability of being successful.
928 Please try this approach before reporting problems with a major
933 If you are updating from a prior version of FreeBSD (even one just
934 a few days old), you should follow this procedure. It is the most
935 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
937 make kernel-toolchain
938 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
939 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
941 To test a kernel once
942 ---------------------
943 If you just want to boot a kernel once (because you are not sure
944 if it works, or if you want to boot a known bad kernel to provide
945 debugging information) run
946 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
947 nextboot -k testkernel
949 To just build a kernel when you know that it won't mess you up
950 --------------------------------------------------------------
951 This assumes you are already running a 5.X system. Replace
952 ${arch} with the architecture of your machine (e.g. "i386",
953 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
955 cd src/sys/${arch}/conf
956 config KERNEL_NAME_HERE
957 cd ../compile/KERNEL_NAME_HERE
962 If this fails, go to the "To build a kernel" section.
964 To rebuild everything and install it on the current system.
965 -----------------------------------------------------------
966 # Note: sometimes if you are running current you gotta do more than
967 # is listed here if you are upgrading from a really old current.
969 <make sure you have good level 0 dumps>
971 make kernel KERNCONF=YOUR_KERNEL_HERE
973 <reboot in single user> [3]
981 To cross-install current onto a separate partition
982 --------------------------------------------------
983 # In this approach we use a separate partition to hold
984 # current's root, 'usr', and 'var' directories. A partition
985 # holding "/", "/usr" and "/var" should be about 2GB in
988 <make sure you have good level 0 dumps>
991 make buildkernel KERNCONF=YOUR_KERNEL_HERE
992 <maybe newfs current's root partition>
993 <mount current's root partition on directory ${CURRENT_ROOT}>
994 make installworld DESTDIR=${CURRENT_ROOT}
995 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
996 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
997 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
998 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
999 <reboot into current>
1000 <do a "native" rebuild/install as described in the previous section>
1001 <maybe install compatibility libraries from src/lib/compat>
1005 To upgrade in-place from 5.x-stable to current
1006 ----------------------------------------------
1007 <make sure you have good level 0 dumps>
1009 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
1011 <reboot in single user> [3]
1018 Make sure that you've read the UPDATING file to understand the
1019 tweaks to various things you need. At this point in the life
1020 cycle of current, things change often and you are on your own
1021 to cope. The defaults can also change, so please read ALL of
1022 the UPDATING entries.
1024 Also, if you are tracking -current, you must be subscribed to
1025 freebsd-current@freebsd.org. Make sure that before you update
1026 your sources that you have read and understood all the recent
1027 messages there. If in doubt, please track -stable which has
1028 much fewer pitfalls.
1030 [1] If you have third party modules, such as vmware, you
1031 should disable them at this point so they don't crash your
1034 [3] From the bootblocks, boot -s, and then do
1039 adjkerntz -i # if CMOS is wall time
1040 Also, when doing a major release upgrade, it is required that
1041 you boot into single user mode to do the installworld.
1043 [4] Note: This step is non-optional. Failure to do this step
1044 can result in a significant reduction in the functionality of the
1045 system. Attempting to do it by hand is not recommended and those
1046 that pursue this avenue should read this file carefully, as well
1047 as the archives of freebsd-current and freebsd-hackers mailing lists
1048 for potential gotchas.
1050 [5] Usually this step is a noop. However, from time to time
1051 you may need to do this if you get unknown user in the following
1052 step. It never hurts to do it all the time. You may need to
1053 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1054 install) after the buildworld before this step if you last updated
1055 from current before 20020224 or from -stable before 20020408.
1057 [8] In order to have a kernel that can run the 4.x binaries
1058 needed to do an installworld, you must include the COMPAT_FREEBSD4
1059 option in your kernel. Failure to do so may leave you with a system
1060 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
1061 is required to run the 5.x binaries on more recent kernels.
1063 Make sure that you merge any new devices from GENERIC since the
1064 last time you updated your kernel config file.
1066 [9] When checking out sources, you must include the -P flag to have
1067 cvs prune empty directories.
1069 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1070 "?=" instead of the "=" assignment operator, so that buildworld can
1071 override the CPUTYPE if it needs to.
1073 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1074 not on the command line, or in /etc/make.conf. buildworld will
1075 warn if it is improperly defined.
1078 This file contains a list, in reverse chronological order, of major
1079 breakages in tracking -current. Not all things will be listed here,
1080 and it only starts on October 16, 2004. Updating files can found in
1081 previous releases if your system is older than this.
