14 20090422: FreeBSD-SA-09:07.libc, FreeBSD-SA-09:08.openssl
15 Don't leak information via uninitialized space in db(3) records.
18 Sanity-check string lengths in order to stop OpenSSL crashing
19 when printing corrupt BMPString or UniversalString objects. [09:08]
22 Following bug-fixes to TCP connection state flags, netstat, systat,
23 and sockstat will need to be rebuilt in order to properly print
24 connections in the TIMEWAIT state.
27 Change IPv6 ephemeral port allocation from sequential to
28 random allocation, like IPv4 has done for more than four years.
29 The implementation shares infrastructure with IPv4. This
30 means that there is only one set of sysctls to control both
31 IPv4 and IPv6. See ip(4) man page for details.
34 A workaround is committed to allow the creation of System V shared
35 memory segment of size > 2 GB on the 64-bit architectures.
36 Due to a limitation of the existing ABI, the shm_segsz member
37 of the struct shmid_ds, returned by shmctl(IPC_STAT) call is
38 wrong for large segments. Note that limits must be explicitely
39 raised to allow such segments to be created.
41 The management interface that is used by ipcs(1) has to be changed
42 in incompatible way. Rebuild the ipcs(1) utility with the new
43 headers after the update. Buildworld/installworld takes care
44 of this issue automatically.
47 The open-source Atheros HAL has been merged from HEAD
49 The kernel compile-time option AH_SUPPORT_AR5416 has been
50 added to support certain newer Atheros parts, particularly
52 The following modules are no longer available, and should be
53 removed from MODULES_OVERRIDE and/or loader.conf:-
54 ath_hal ath_rate_amrr ath_rate_onoe ath_rate_sample
57 ZFS users on amd64 machines with 4GB or more of RAM should
58 reevaluate their need for setting vm.kmem_size_max and
59 vm.kmem_size manually. In fact, after recent changes to the
60 kernel, the default value of vm.kmem_size is larger than the
61 suggested manual setting in most ZFS/FreeBSD tuning guides.
64 Multi-IPv4/v6/no-IP jail support was merged to STABLE.
65 You need to rebuild jls(8) and to use the new features
66 jail(8), jexec(8) and cpuset(1) with a new kernel.
67 __FreeBSD_version was bumped to 701103.
70 NTFS has been removed from GENERIC kernel on amd64 to match
71 GENERIC on i386. Should not cause any issues since mount_ntfs(8)
72 will load ntfs.ko module automatically when NTFS support is
73 actually needed, unless ntfs.ko is not installed or security
74 level prohibits loading kernel modules. If either is the case,
75 "options NTFS" has to be added into kernel config.
78 powerd(8) was updated to get better SMP support.
79 Meanings of the -i and -r command line options were changed.
82 snd_hda(4) driver was updated to version 20081226_0122.
84 Due to added HDMI audio and logical audio devices support, updated
85 driver often provides several PCM devices. In some cases it can make
86 system default audio device no longer correspond to the users's
87 habbitual audio connectors. In such cases wanted device can be
88 specified in audio application setup or defined globally via
89 hw.snd.default_unit sysctl according to sound(4) and snd_hda(4)
96 ntpd has been upgraded to 4.2.4p5.
99 OpenSSH has been upgraded to 5.1p1.
102 DTrace support was merged to STABLE today. In the best
103 tradition of "the dog ate my homework", subversion decided
104 that the commit message was too large and opted not to send
105 it. It was a stealth commit!
107 A 'make buildkernel' will now default to build the kernel
108 and modules with both DTrace kernel hooks and CTF data ready
111 After you have installed both world and the kernel, and
112 rebooted, you can 'kldload dtraceall' to load all the DTrace
113 kernel modules and then you're set to run the 'dtrace'
116 For DTrace documentation, refer to:
117 <http://wikis.sun.com/display/DTrace/Documentation>
119 We are limited to kernel tracing at the moment, so the pid
120 provider is not available.
122 For the syscall provider, note that the arguments to the
123 return probes are the same as for the entry probes.
126 Today STABLE got a reorganization of the Intel E1000
127 driver code. In order to better support our new adapters
128 there is a new driver, igb, that is now to be used for
129 either the 82575 or 82576 adapters. The source however,
130 is all now in sys/dev/e1000, both em and igb drivers are
131 built from that common directory if you configure them
132 in the kernel. Making loadable drivers still happens in
133 the same place: sys/modules/[em, igb].
135 The important thing to note is that the 82575 adapters
136 were supported in the em driver in 7.0, but now needed
137 to be moved into igb, so if you have the effected cards
138 be sure and make any script changes to follow the name
141 There are only 3 PCI ID's effected in this change:
142 0x10A7, 0x10A9, and 0x10D6
143 So you can know ahead of time if they will be effected,
144 these will now be supported in the igb driver. That
145 driver will also support the new 82576 followon.
147 The driver reorg in STABLE is inconvenient but it really
148 was necessary for Intel to do this, and I figured it was
149 better to have this small admin type issue than not to
150 have support for this new hardware for a whole release
154 I have MFC'd in code to support multiple routing tables.
155 see the man pages setfib(1) and setfib(2).
156 This is a backwards compatible version,
157 but to make use of it you need to compile your kernel
158 with options ROUTETABLES=2 (or more up to 16).
164 Note the addition of m_collapse for compacting mbuf chains.
167 The AT keyboard emulation of sunkbd(4) has been turned on
168 by default. In order to make the special symbols of the Sun
169 keyboards driven by sunkbd(4) work under X these now have
170 to be configured the same way as Sun USB keyboards driven
171 by ukbd(4) (which also does AT keyboard emulation), f.e.:
173 Option "XkbLayout" "us"
174 Option "XkbRules" "xorg"
175 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us"
178 It has been decided that it is desirable to provide ABI
179 backwards compatibility to the FreeBSD 4/5/6 versions of the
180 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was
181 broken with the introduction of PCI domain support (see the
182 20070930 entry). Unfortunately, this required the ABI of
183 PCIOCGETCONF to be broken again in order to be able to
184 provide backwards compatibility to the old version of that
185 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled
186 again. As for prominent ports this affects neither pciutils
187 nor xorg-server this time, the hal port needs to be rebuilt
194 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and
195 WITHOUT_LIBTHR are set.
198 The PCI code has been made aware of PCI domains. This means that
199 the location strings as used by pciconf(8) etc are now in the
200 following format: pci<domain>:<bus>:<device>[:<function>]. It
201 also means that consumers of <sys/pciio.h> potentially need to
202 be recompiled; this includes the hal and xorg-server ports.
205 The caching daemon (cached) was renamed to nscd. nscd.conf
206 configuration file should be used instead of cached.conf and
207 nscd_enable, nscd_pidfile and nscd_flags options should be used
208 instead of cached_enable, cached_pidfile and cached_flags in
212 The new IPsec code is now compiled in using the IPSEC option. The
213 IPSEC option now requires "device crypto" be defined in your kernel
214 configuration. The FAST_IPSEC kernel option is now deprecated.
217 The packet filter (pf) code has been updated to OpenBSD 4.1 Please
218 note the changed syntax - keep state is now on by default. Also
219 note the fact that ftp-proxy(8) has been changed from bottom up and
220 has been moved from libexec to usr/sbin. Changes in the ALTQ
221 handling also affect users of IPFW's ALTQ capabilities.
224 Remove KAME IPsec in favor of FAST_IPSEC, which is now the
225 only IPsec supported by FreeBSD. The new IPsec stack
226 supports both IPv4 and IPv6. The kernel option will change
227 after the code changes have settled in. For now the kernel
228 option IPSEC is deprecated and FAST_IPSEC is the only option, that
229 will change after some settling time.
232 The wicontrol(8) utility has been removed from the base system. wi(4)
233 cards should be configured using ifconfig(8), see the man page for more
237 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver
238 instead of the nve(4) driver. Please update your configuration
242 By default, /etc/rc.d/sendmail no longer rebuilds the aliases
243 database if it is missing or older than the aliases file. If
244 desired, set the new rc.conf option sendmail_rebuild_aliases
245 to "YES" to restore that functionality.
248 The IPv4 multicast socket code has been considerably modified, and
249 moved to the file sys/netinet/in_mcast.c. Initial support for the
250 RFC 3678 Source-Specific Multicast Socket API has been added to
251 the IPv4 network stack.
253 Strict multicast and broadcast reception is now the default for
254 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable
255 has now been removed.
257 The RFC 1724 hack for interface selection has been removed; the use
258 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has
259 been added to replace it. Consumers such as routed will soon be
260 updated to reflect this.
262 These changes affect users who are running routed(8) or rdisc(8)
263 from the FreeBSD base system on point-to-point or unnumbered
267 The net80211 layer has changed significantly and all wireless
268 drivers that depend on it need to be recompiled. Further these
269 changes require that any program that interacts with the wireless
270 support in the kernel be recompiled; this includes: ifconfig,
271 wpa_supplicant, hostapd, and wlanstats. Users must also, for
272 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules
273 if they use modules for wireless support. These modules implement
274 scanning support for station and ap modes, respectively. Failure
275 to load the appropriate module before marking a wireless interface
276 up will result in a message to the console and the device not
280 The pam_nologin(8) module ceases to provide an authentication
281 function and starts providing an account management function.
282 Consequent changes to /etc/pam.d should be brought in using
283 mergemaster(8). Third-party files in /usr/local/etc/pam.d may
284 need manual editing as follows. Locate this line (or similar):
286 auth required pam_nologin.so no_warn
288 and change it according to this example:
290 account required pam_nologin.so no_warn
292 That is, the first word needs to be changed from "auth" to
293 "account". The new line can be moved to the account section
294 within the file for clarity. Not updating pam.conf(5) files
295 will result in nologin(5) ignored by the respective services.
298 The ether_ioctl() function has been synchronized with ioctl(2)
299 and ifnet.if_ioctl. Due to that, the size of one of its arguments
300 has changed on 64-bit architectures. All kernel modules using
301 ether_ioctl() need to be rebuilt on such architectures.
304 Improved INCLUDE_CONFIG_FILE support has been introduced to the
305 config(8) utility. In order to take advantage of this new
306 functionality, you are expected to recompile and install
307 src/usr.sbin/config. If you don't rebuild config(8), and your
308 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel
309 build will be broken because of a missing "kernconfstring"
313 Symbol versioning is enabled by default. To disable it, use
314 option WITHOUT_SYMVER. It is not advisable to attempt to
315 disable symbol versioning once it is enabled; your installworld
316 will break because a symbol version-less libc will get installed
317 before the install tools. As a result, the old install tools,
318 which previously had symbol dependencies to FBSD_1.0, will fail
319 because the freshly installed libc will not have them.
321 The default threading library (providing "libpthread") has been
322 changed to libthr. If you wish to have libkse as your default,
323 use option DEFAULT_THREAD_LIB=libkse for the buildworld.
326 The ABI breakage in sendmail(8)'s libmilter has been repaired
327 so it is no longer necessary to recompile mail filters (aka,
328 milters). If you recompiled mail filters after the 20070408
329 note, it is not necessary to recompile them again.
332 The new trunk(4) driver has been renamed to lagg(4) as it better
333 reflects its purpose. ifconfig will need to be recompiled.
336 sendmail(8) has been updated to version 8.14.1. Mail filters
337 (aka, milters) compiled against the libmilter included in the
338 base operating system should be recompiled.
341 Firmwares for ipw(4) and iwi(4) are now included in the base tree.
342 In order to use them one must agree to the respective LICENSE in
343 share/doc/legal and define legal.intel_<name>.license_ack=1 via
344 loader.conf(5) or kenv(1). Make sure to deinstall the now
345 deprecated modules from the respective firmware ports.
348 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3)
349 were removed from FreeBSD's libc. These originally came from INRIA
350 IPv6. Nothing in FreeBSD ever used them. They may be regarded as
351 deprecated in previous releases.
352 The AF_LINK support for getnameinfo(3) was merged from NetBSD to
353 replace it as a more portable (and re-entrant) API.
356 To support interrupt filtering a modification to the newbus API
357 has occurred, ABI was broken and __FreeBSD_version was bumped
358 to 700031. Please make sure that your kernel and modules are in
360 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941
363 The IPv6 multicast forwarding code may now be loaded into GENERIC
364 kernels by loading the ip_mroute.ko module. This is built into the
365 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are
366 set; see src.conf(5) for more information.
369 The output of netstat -r has changed. Without -n, we now only
370 print a "network name" without the prefix length if the network
371 address and mask exactly match a Class A/B/C network, and an entry
372 exists in the nsswitch "networks" map.
373 With -n, we print the full unabbreviated CIDR network prefix in
374 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default".
375 This change is in preparation for changes such as equal-cost
376 multipath, and to more generally assist operational deployment
377 of FreeBSD as a modern IPv4 router.
380 PIM has been turned on by default in the IPv4 multicast
381 routing code. The kernel option 'PIM' has now been removed.
382 PIM is now built by default if option 'MROUTING' is specified.
383 It may now be loaded into GENERIC kernels by loading the
387 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing
388 has been removed. Its functionality may be achieved by explicitly
389 configuring gif(4) interfaces and using the 'phyint' keyword in
391 XORP does not support source-routed IPv4 multicast tunnels nor the
392 integrated IPIP tunneling, therefore it is not affected by this
393 change. The __FreeBSD_version macro has been bumped to 700030.
396 Support for PCI Message Signalled Interrupts has been
397 re-enabled in the bge driver, only for those chips which are
398 believed to support it properly. If there are any problems,
399 MSI can be disabled completely by setting the
400 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0
404 Support for PCI Message Signalled Interrupts has been
405 disabled again in the bge driver. Many revisions of the
406 hardware fail to support it properly. Support can be
407 re-enabled by removing the #define of BGE_DISABLE_MSI in
408 "src/sys/dev/bge/if_bge.c".
411 Support for PCI Message Signalled Interrupts has been added
412 to the bge driver. If there are any problems, MSI can be
413 disabled completely by setting the 'hw.pci.enable_msi' and
414 'hw.pci.enable_msix' tunables to 0 in the loader.
417 The removal of several facets of the experimental Threading
418 system from the kernel means that the proc and thread structures
419 have changed quite a bit. I suggest all kernel modules that might
420 reference these structures be recompiled.. Especially the
424 Sound infrastructure has been updated with various fixes and
425 improvements. Most of the changes are pretty much transparent,
426 with exceptions of followings:
427 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been
428 moved to their own dev sysctl nodes, for example:
429 hw.snd.pcm0.vchans -> dev.pcm.0.vchans
430 2) /dev/dspr%d.%d has been deprecated. Each channel now has its
431 own chardev in the form of "dsp%d.<function>%d", where <function>
432 is p = playback, r = record and v = virtual, respectively. Users
433 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d".
434 This does not affect those who are using "/dev/dsp".
437 geom(4)'s gmirror(8) class metadata structure has been
438 rev'd from v3 to v4. If you update across this point and
439 your metadata is converted for you, you will not be easily
440 able to downgrade since the /boot/kernel.old/geom_mirror.ko
441 kernel module will be unable to read the v4 metadata. You
442 can resolve this by doing from the loader(8) prompt:
444 set vfs.root.mountfrom="ufs:/dev/XXX"
446 where XXX is the root slice of one of the disks that composed
447 the mirror (i.e.: /dev/ad0s1a). You can then rebuild
448 the array the same way you built it originally.
451 The following binaries have been disconnected from the build:
452 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs,
453 and mount_std. The functionality of these programs has been
454 moved into the mount program. For example, to mount a devfs
455 filesystem, instead of using mount_devfs, use: "mount -t devfs".
456 This does not affect entries in /etc/fstab, since entries in
457 /etc/fstab are always processed with "mount -t fstype".
460 Support for PCI Message Signalled Interrupts on i386 and amd64
461 has been added to the kernel and various drivers will soon be
462 updated to use MSI when it is available. If there are any problems,
463 MSI can be disabled completely by setting the 'hw.pci.enable_msi'
464 and 'hw.pci.enable_msix' tunables to 0 in the loader.
467 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING.
468 The lockmgr object layout has been changed as a result of having
469 a lock_object embedded in it. As a consequence all file system
470 kernel modules must be re-compiled. The mutex profiling man page
471 has not yet been updated to reflect this change.
474 KSE in the kernel has now been made optional and turned on by
475 default. Use 'nooption KSE' in your kernel config to turn it
476 off. All kernel modules *must* be recompiled after this change.
477 There-after, modules from a KSE kernel should be compatible with
478 modules from a NOKSE kernel due to the temporary padding fields
479 added to 'struct proc'.
482 mrouted and its utilities have been removed from the base system.
485 Some ioctl(2) command codes have changed. Full backward ABI
486 compatibility is provided if the "options COMPAT_FREEBSD6" is
487 present in the kernel configuration file. Make sure to add
488 this option to your kernel config file, or recompile X.Org
489 and the rest of ports; otherwise they may refuse to work.
492 tcpslice has been removed from the base system.
495 The sizes of struct tcpcb (and struct xtcpcb) have changed due to
496 the rewrite of TCP syncookies. Tools like netstat, sockstat, and
497 systat needs to be rebuilt.
500 libpcap updated to v0.9.4 and tcpdump to v3.9.4
503 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
504 for IPFIREWALL_FORWARD is now as it was before when it was first
505 committed and for years after. The behaviour is now ON.
508 enigma(1)/crypt(1) utility has been changed on 64 bit architectures.
509 Now it can decrypt files created from different architectures.
510 Unfortunately, it is no longer able to decrypt a cipher text
511 generated with an older version on 64 bit architectures.
512 If you have such a file, you need old utility to decrypt it.
515 The interface version of the i4b kernel part has changed. So
516 after updating the kernel sources and compiling a new kernel,
517 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
518 be rebuilt, and vice versa.
521 The XBOX kernel now defaults to the nfe(4) driver instead of
522 the nve(4) driver. Please update your configuration
526 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx
527 PCnet family of NICs has been removed. The new le(4) driver serves
528 as an equivalent but cross-platform replacement with the pcn(4)
529 driver still providing performance-optimized support for the subset
530 of AMD Am79C971 PCnet-FAST and greater chips as before.
533 The machdep.* sysctls and the adjkerntz utility have been
534 modified a bit. The new adjkerntz utility uses the new
535 sysctl names and sysctlbyname() calls, so it may be impossible
536 to run an old /sbin/adjkerntz utility in single-user mode
537 with a new kernel. Replace the `adjkerntz -i' step before
538 `make installworld' with:
540 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i
542 and proceed as usual with the rest of the installworld-stage
543 steps. Otherwise, you risk installing binaries with their
544 timestamp set several hours in the future, especially if
545 you are running with local time set to GMT+X hours.
548 The ip6fw utility has been removed. The behavior provided by
549 ip6fw has been in ipfw2 for a good while and the rc.d scripts
550 have been updated to deal with it. There are some rules that
551 might not migrate cleanly. Use rc.firewall6 as a template to
555 The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
556 attachments have been removed. Make sure to configure scc(4)
557 on sparc64. Note also that by default puc(4) will use uart(4)
558 and not sio(4) for serial ports because interrupt handling has
559 been optimized for multi-port serial cards and only uart(4)
560 implements the interface to support it.
563 The scc(4) driver replaces puc(4) for Serial Communications
564 Controllers (SCCs) like the Siemens SAB82532 and the Zilog
565 Z8530. On sparc64, it is advised to add scc(4) to the kernel
566 configuration to make sure that the serial ports remain
570 Most world/kernel related NO_* build options changed names.
571 New knobs have common prefixes WITHOUT_*/WITH_* (modelled
572 after FreeBSD ports) and should be set in /etc/src.conf
573 (the src.conf(5) manpage is provided). Full backwards
574 compatibility is maintained for the time being though it's
575 highly recommended to start moving old options out of the
576 system-wide /etc/make.conf file into the new /etc/src.conf
577 while also properly renaming them. More conversions will
578 likely follow. Posting to current@:
580 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html
583 The NETSMBCRYPTO kernel option has been retired because its
584 functionality is always included in NETSMB and smbfs.ko now.
587 The TDFX_LINUX kernel option was retired and replaced by the
588 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko
589 kernel module. Loading it alone should suffice to get 3dfx support
590 for Linux apps because it will pull in 3dfx.ko and linux.ko through
594 The 'audit' group was added to support the new auditing functionality
595 in the base system. Be sure to follow the directions for updating,
596 including the requirement to run mergemaster -p.
599 The kernel ABI to file system modules was changed on i386.
600 Please make sure that your kernel and modules are in sync.
603 This actually occured some time ago, but installing the kernel
604 now also installs a bunch of symbol files for the kernel modules.
605 This increases the size of /boot/kernel to about 67Mbytes. You
606 will need twice this if you will eventually back this up to kernel.old
607 on your next install.
608 If you have a shortage of room in your root partition, you should add
609 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes"
610 to your /etc/make.conf.
613 libc's malloc implementation has been replaced. This change has the
614 potential to uncover application bugs that previously went unnoticed.
615 See the malloc(3) manual page for more details.
618 The generic netgraph(4) cookie has been changed. If you upgrade
619 kernel passing this point, you also need to upgrade userland
620 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4.
623 si(4)'s device files now contain the unit number.
624 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
627 The kernel ABI was mostly destroyed due to a change in the size
628 of struct lock_object which is nested in other structures such
629 as mutexes which are nested in all sorts of other structures.
630 Make sure your kernel and modules are in sync.
633 The page coloring algorithm in the VM subsystem was converted
634 from tuning with kernel options to autotuning. Please remove
635 any PQ_* option except PQ_NOOPT from your kernel config.
638 The net80211-related tools in the tools/tools/ath directory
639 have been moved to tools/tools/net80211 and renamed with a
640 "wlan" prefix. Scripts that use them should be adjusted
644 Scripts in the local_startup directories (as defined in
645 /etc/defaults/rc.conf) that have the new rc.d semantics will
646 now be run as part of the base system rcorder. If there are
647 errors or problems with one of these local scripts, it could
648 cause boot problems. If you encounter such problems, boot in
649 single user mode, remove that script from the */rc.d directory.
650 Please report the problem to the port's maintainer, and the
651 freebsd-ports@freebsd.org mailing list.
654 The nodev mount option was deprecated in RELENG_6 (where it
655 was a no-op), and is now unsupported. If you have nodev or dev listed
656 in /etc/fstab, remove it, otherwise it will result in a mount error.
659 ABI between ipfw(4) and ipfw(8) has been changed. You need
660 to rebuild ipfw(8) when rebuilding kernel.
663 rp(4)'s device files now contain the unit number.
664 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
667 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
668 Its /etc/rc.conf.d configuration file has been `ppp' from
669 the beginning, and hence there is no need to touch it.
672 Now most modules get their build-time options from the kernel
673 configuration file. A few modules still have fixed options
674 due to their non-conformant implementation, but they will be
675 corrected eventually. You may need to review the options of
676 the modules in use, explicitly specify the non-default options
677 in the kernel configuration file, and rebuild the kernel and
681 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
682 to turn polling(4) on your interfaces.
685 The old bridge(4) implementation was retired. The new
686 if_bridge(4) serves as a full functional replacement.
689 The ai_addrlen of a struct addrinfo was changed to a socklen_t
690 to conform to POSIX-2001. This change broke an ABI
691 compatibility on 64 bit architecture. You have to recompile
692 userland programs that use getaddrinfo(3) on 64 bit
696 RELENG_6 branched here.
699 The pccard_ifconfig rc.conf variable has been removed and a new
700 variable, ifconfig_DEFAULT has been introduced. Unlike
701 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
702 do not have ifconfig_ifn entries rather than just those in
703 removable_interfaces.
706 Some previous versions of PAM have permitted the use of
707 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
708 to third party PAM modules in /usr/local/lib. A change has been
709 made to require the use of absolute paths in order to avoid
710 ambiguity and dependence on library path configuration, which may
711 affect existing configurations.
714 Major changes to network interface API. All drivers must be
715 recompiled. Drivers not in the base system will need to be
716 updated to the new APIs.
719 Changes were made to kinfo_proc in sys/user.h. Please recompile
720 userland, or commands like `fstat', `pkill', `ps', `top' and `w'
721 will not behave correctly.
723 The API and ABI for hwpmc(4) have changed with the addition
724 of sampling support. Please recompile lib/libpmc(3) and
725 usr.sbin/{pmcstat,pmccontrol}.
728 The OpenBSD dhclient was imported in place of the ISC dhclient
729 and the network interface configuration scripts were updated
730 accordingly. If you use DHCP to configure your interfaces, you
731 must now run devd. Also, DNS updating was lost so you will need
732 to find a workaround if you use this feature.
734 The '_dhcp' user was added to support the OpenBSD dhclient. Be
735 sure to run mergemaster -p (like you are supposed to do every time
739 if_bridge was added to the tree. This has changed struct ifnet.
740 Please recompile userland and all network related modules.
743 The n_net of a struct netent was changed to an uint32_t, and
744 1st argument of getnetbyaddr() was changed to an uint32_t, to
745 conform to POSIX-2001. These changes broke an ABI
746 compatibility on 64 bit architecture. With these changes,
747 shlib major of libpcap was bumped. You have to recompile
748 userland programs that use getnetbyaddr(3), getnetbyname(3),
749 getnetent(3) and/or libpcap on 64 bit architecture.
752 Kernel parsing of extra options on '#!' first lines of shell
753 scripts has changed. Lines with multiple options likely will
754 fail after this date. For full details, please see
755 http://people.freebsd.org/~gad/Updating-20050528.txt
758 The packet filter (pf) code has been updated to OpenBSD 3.7
759 Please note the changed anchor syntax and the fact that
760 authpf(8) now needs a mounted fdescfs(5) to function.
763 The NO_MIXED_MODE kernel option has been removed from the i386
764 amd64 platforms as its use has been superceded by the new local
765 APIC timer code. Any kernel config files containing this option
769 The on-disk format of LC_CTYPE files was changed to be machine
770 independent. Please make sure NOT to use NO_CLEAN buildworld
771 when crossing this point. Crossing this point also requires
772 recompile or reinstall of all locale depended packages.
775 The ifi_epoch member of struct if_data has been changed to
776 contain the uptime at which the interface was created or the
777 statistics zeroed rather then the wall clock time because
778 wallclock time may go backwards. This should have no impact
779 unless an snmp implementation is using this value (I know of
783 The acpi_perf and acpi_throttle drivers are now part of the
784 acpi(4) main module. They are no longer built separately.
787 The layout of struct image_params has changed. You have to
788 recompile all compatibility modules (linux, svr4, etc) for use
792 The p4tcc driver has been merged into cpufreq(4). This makes
793 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
794 compile in "device cpufreq" to restore this functionality.
797 The responsibility of recomputing the file system summary of
798 a SoftUpdates-enabled dirty volume has been transferred to the
799 background fsck. A rebuild of fsck(8) utility is recommended
800 if you have updated the kernel.
802 To get the old behavior (recompute file system summary at mount
803 time), you can set vfs.ffs.compute_summary_at_mount=1 before
804 mounting the new volume.
807 The cpufreq import is complete. As part of this, the sysctls for
808 acpi(4) throttling have been removed. The power_profile script
809 has been updated, so you can use performance/economy_cpu_freq in
810 rc.conf(5) to set AC on/offline cpu frequencies.
813 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
814 requires recompiling libnetgraph and userland netgraph utilities.
817 Support for abbreviated forms of a number of ipfw options is
818 now deprecated. Warnings are printed to stderr indicating the
819 correct full form when a match occurs. Some abbreviations may
820 be supported at a later date based on user feedback. To be
821 considered for support, abbreviations must be in use prior to
822 this commit and unlikely to be confused with current key words.
825 By a popular demand, a lot of NOFOO options were renamed
826 to NO_FOO (see bsd.compat.mk for a full list). The old
827 spellings are still supported, but will cause annoying
828 warnings on stderr. Make sure you upgrade properly (see
829 the COMMON ITEMS: section later in this file).
832 Auto-loading of ancillary wlan modules such as wlan_wep has
833 been temporarily disabled; you need to statically configure
834 the modules you need into your kernel or explicitly load them
835 prior to use. Specifically, if you intend to use WEP encryption
836 with an 802.11 device load/configure wlan_wep; if you want to
837 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
838 and wlan_xauth as required.
841 The behaviour of ppp(8) has changed slightly. If lqr is enabled
842 (``enable lqr''), older versions would revert to LCP ECHO mode on
843 negotiation failure. Now, ``enable echo'' is required for this
844 behaviour. The ppp version number has been bumped to 3.4.2 to
848 The wlan support has been updated to split the crypto support
849 into separate modules. For static WEP you must configure the
850 wlan_wep module in your system or build and install the module
851 in place where it can be loaded (the kernel will auto-load
852 the module when a wep key is configured).
855 The ath driver has been updated to split the tx rate control
856 algorithm into a separate module. You need to include either
857 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
860 Support for systems with an 80386 CPU has been removed. Please
861 use FreeBSD 5.x or earlier on systems with an 80386.
864 We have had a hack which would mount the root filesystem
865 R/W if the device were named 'md*'. As part of the vnode
866 work I'm doing I have had to remove this hack. People
867 building systems which use preloaded MD root filesystems
868 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
869 their /etc/rc scripts.
872 FreeBSD 5.3 shipped here.
875 The size of struct tcpcb has changed again due to the removal
876 of RFC1644 T/TCP. You have to recompile userland programs that
877 read kmem for tcp sockets directly (netstat, sockstat, etc.)
880 The size of struct tcpcb has changed. You have to recompile
881 userland programs that read kmem for tcp sockets directly
882 (netstat, sockstat, etc.)
885 RELENG_5 branched here. For older entries, please see updating
886 in the RELENG_5 branch.
892 Avoid using make -j when upgrading. From time to time in the
893 past there have been problems using -j with buildworld and/or
894 installworld. This is especially true when upgrading between
895 "distant" versions (eg one that cross a major release boundary
896 or several minor releases, or when several months have passed
897 on the -current branch).
899 Sometimes, obscure build problems are the result of environment
900 poisoning. This can happen because the make utility reads its
901 environment when searching for values for global variables.
902 To run your build attempts in an "environmental clean room",
903 prefix all make commands with 'env -i '. See the env(1) manual
904 page for more details.
906 When upgrading from one major version to another it is generally
907 best to upgrade to the latest code in the currently installed branch
908 first, then do an upgrade to the new branch. This is the best-tested
909 upgrade path, and has the highest probability of being successful.
910 Please try this approach before reporting problems with a major
915 If you are updating from a prior version of FreeBSD (even one just
916 a few days old), you should follow this procedure. It is the most
917 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
919 make kernel-toolchain
920 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
921 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
923 To test a kernel once
924 ---------------------
925 If you just want to boot a kernel once (because you are not sure
926 if it works, or if you want to boot a known bad kernel to provide
927 debugging information) run
928 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
929 nextboot -k testkernel
931 To just build a kernel when you know that it won't mess you up
932 --------------------------------------------------------------
933 This assumes you are already running a 5.X system. Replace
934 ${arch} with the architecture of your machine (e.g. "i386",
935 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
937 cd src/sys/${arch}/conf
938 config KERNEL_NAME_HERE
939 cd ../compile/KERNEL_NAME_HERE
944 If this fails, go to the "To build a kernel" section.
946 To rebuild everything and install it on the current system.
947 -----------------------------------------------------------
948 # Note: sometimes if you are running current you gotta do more than
949 # is listed here if you are upgrading from a really old current.
951 <make sure you have good level 0 dumps>
953 make kernel KERNCONF=YOUR_KERNEL_HERE
955 <reboot in single user> [3]
963 To cross-install current onto a separate partition
964 --------------------------------------------------
965 # In this approach we use a separate partition to hold
966 # current's root, 'usr', and 'var' directories. A partition
967 # holding "/", "/usr" and "/var" should be about 2GB in
970 <make sure you have good level 0 dumps>
973 make buildkernel KERNCONF=YOUR_KERNEL_HERE
974 <maybe newfs current's root partition>
975 <mount current's root partition on directory ${CURRENT_ROOT}>
976 make installworld DESTDIR=${CURRENT_ROOT}
977 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
978 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
979 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
980 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
981 <reboot into current>
982 <do a "native" rebuild/install as described in the previous section>
983 <maybe install compatibility libraries from src/lib/compat>
987 To upgrade in-place from 5.x-stable to current
988 ----------------------------------------------
989 <make sure you have good level 0 dumps>
991 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
993 <reboot in single user> [3]
1000 Make sure that you've read the UPDATING file to understand the
1001 tweaks to various things you need. At this point in the life
1002 cycle of current, things change often and you are on your own
1003 to cope. The defaults can also change, so please read ALL of
1004 the UPDATING entries.
1006 Also, if you are tracking -current, you must be subscribed to
1007 freebsd-current@freebsd.org. Make sure that before you update
1008 your sources that you have read and understood all the recent
1009 messages there. If in doubt, please track -stable which has
1010 much fewer pitfalls.
1012 [1] If you have third party modules, such as vmware, you
1013 should disable them at this point so they don't crash your
1016 [3] From the bootblocks, boot -s, and then do
1021 adjkerntz -i # if CMOS is wall time
1022 Also, when doing a major release upgrade, it is required that
1023 you boot into single user mode to do the installworld.
1025 [4] Note: This step is non-optional. Failure to do this step
1026 can result in a significant reduction in the functionality of the
1027 system. Attempting to do it by hand is not recommended and those
1028 that pursue this avenue should read this file carefully, as well
1029 as the archives of freebsd-current and freebsd-hackers mailing lists
1030 for potential gotchas.
1032 [5] Usually this step is a noop. However, from time to time
1033 you may need to do this if you get unknown user in the following
1034 step. It never hurts to do it all the time. You may need to
1035 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1036 install) after the buildworld before this step if you last updated
1037 from current before 20020224 or from -stable before 20020408.
1039 [8] In order to have a kernel that can run the 4.x binaries
1040 needed to do an installworld, you must include the COMPAT_FREEBSD4
1041 option in your kernel. Failure to do so may leave you with a system
1042 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
1043 is required to run the 5.x binaries on more recent kernels.
1045 Make sure that you merge any new devices from GENERIC since the
1046 last time you updated your kernel config file.
1048 [9] When checking out sources, you must include the -P flag to have
1049 cvs prune empty directories.
1051 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1052 "?=" instead of the "=" assignment operator, so that buildworld can
1053 override the CPUTYPE if it needs to.
1055 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1056 not on the command line, or in /etc/make.conf. buildworld will
1057 warn if it is improperly defined.
1060 This file contains a list, in reverse chronological order, of major
1061 breakages in tracking -current. Not all things will be listed here,
1062 and it only starts on October 16, 2004. Updating files can found in
1063 previous releases if your system is older than this.
