13 NOTE TO PEOPLE WHO THINK THAT FreeBSD 6.x IS SLOW:
14 FreeBSD 6.x has many debugging features turned on, in
15 both the kernel and userland. These features attempt to detect
16 incorrect use of system primitives, and encourage loud failure
17 through extra sanity checking and fail stop semantics. They
18 also substantially impact system performance. If you want to
19 do performance measurement, benchmarking, and optimization,
20 you'll want to turn them off. This includes various WITNESS-
21 related kernel options, INVARIANTS, malloc debugging flags
22 in userland, and various verbose features in the kernel. Many
23 developers choose to disable these features on build machines
24 to maximize performance.
27 The following libraries had their version number bumped up:
28 /lib/libm.so.2 -> libm.so.3
29 /lib/libreadline.so.4 -> libreadline.so.5
30 /usr/lib/libhistory.so.4 -> libhistory.so.5
31 /usr/lib/libopie.so.2 -> libopie.so.3
32 /usr/lib/libpcap.so.2 -> libpcap.so.3
33 FreeBSD 4.10 versions of these libraries will be added to the
34 compat4x collection. If you expect to be able to run old 4.X
35 executables you will need to remove the old versions of these
36 libraries. However note that any 5.X executables you have built
37 will stop working once you remove those old libraries. You should
38 have all your ports/packages rebuilt before removing the old
41 As a temporary measure, if you do not have any 4.X executables,
42 you can add the following lines to /etc/libmap.conf to force
43 5.X executables to use the new libraries:
45 libhistory.so.4 libhistory.so.5
47 libopie.so.2 libopie.so.3
48 libpcap.so.2 libpcap.so.3
49 libreadline.so.4 libreadline.so.5
52 The pfil API has gained an additional argument to pass an inpcb.
53 You should rebuild all pfil consuming modules: ipfw, ipfilter
57 If enabled, the default is now to run named in a chroot
58 "sandbox." For users with existing configurations in
59 /etc/namedb the migration should be simple. Upgrade your
60 world as usual, then after installworld but before
61 mergemaster do the following:
63 /etc/rc.d/syslogd stop
64 If named is running: /etc/rc.d/named stop
67 mkdir -p /var/named/etc/namedb
68 cp -Rp namedb.bak/* /var/named/etc/namedb/
69 mergemaster (with your usual options)
70 If using the generated localhost* files:
71 cd /var/named/etc/namedb
72 /bin/sh make-localhost
73 rm -f localhost-v6.rev localhost.rev
74 /etc/rc.d/syslogd start
77 If you are using a custom configuration, or if you have
78 customised the named_* variables in /etc/rc.conf[.local]
79 then you may have to adjust the instructions accordingly.
80 It is suggested that you carefully examine the new named
81 variables in /etc/defaults/rc.conf and the options in
82 /var/named/etc/namedb/named.conf to see if they might
86 BIND 9 has been imported into the base, and is now fully
87 functional. BIND 8 has now been removed. There are numerous
88 differences between BIND 8 and 9, and users with critical
89 named installations should read the migration documentation
90 in /usr/share/doc/bind9/misc/migration. There is also a
91 new instruction manual in /usr/share/doc/bind9/arm.
93 The key differences that most users will experience are in
94 how picky BIND 9 is about zone file format. If you are using
95 named as a resolving (caching) name server, you will likely
98 The following files are part of the old BIND 8 installation
99 and should be removed:
100 /usr/bin/dnskeygen /usr/bin/dnsquery /usr/libexec/named-xfer
101 /usr/sbin/named.restart /usr/sbin/ndc
103 The following files have moved to /usr/bin, and should be
104 removed from their old locations:
105 /usr/sbin/nslookup /usr/sbin/nsupdate
108 The format of the pflogd(8) logfile "/var/log/pflog" has changed for
109 architectures that have a 64 bit long type to make it compatible to
110 the standard pcap format. In order to prevent corruption move away
111 any old logfile before using a new pflogd(8).
114 debug.witness_* has been renamed to debug.witness.*. There are
115 compatibility tunables left in for a few days. Update loader.conf
119 The ifi_epoch change has been reverted because the ABI breakage
120 was too extensive. If you are running with a kernel/userland
121 containing the initial change (20040830), you should heed the
122 warning about ifconfig incompatibility when upgrading again.
123 With this change, 5.3 and 6.0 ifconfigs and kernels are once
127 A new variable, ifi_epoch, has been added to struct if_data
128 which is part if struct ifnet. This means all network drivers
129 and network monitoring applications need to be recompiled.
131 WARNING WARNING WARNING WARNING WARNING WARNING WARNING
133 This also breaks ifconfig compatibility. An old ifconfig will
134 not work with the new kernel and a new ifconfig will not work
135 with the old. It is strongly recommended that you make a copy
136 of your old ifconfig before installworld. If you are installing
137 remotely, you must copy over a new ifconfig before rebooting in
141 The default configuration for the network stack has been changed
142 such that it now runs without the Giant lock unless configured
143 otherwise. If you experience network-related instability, you
144 may wish to try setting "debug.mpsafenet=0" or compiling the
145 kernel with "options NET_WITH_GIANT". Details on the netperf
146 project may be found at:
148 http://www.watson.org/~robert/freebsd/netperf/
150 Including the 20040828 announcement of configuration change
154 PFIL_HOOKS are a fixed part of the network stack now and do not
155 need to be specified in the kernel configuration file anymore.
158 Netgraph changed its message format slightly to align the data
159 portion well on 64 bit machines.
160 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
161 pppoed, bluetooth, ATM) should be recompiled when a new kernel
165 IPFW has been converted to use PFIL_HOOKS. This change is
166 transparent to userland and preserves the ipfw ABI. The ipfw
167 core packet inspection and filtering functions have not been
168 changed, only how ipfw is invoked is different. Note that
169 "option PFIL_HOOKS" is required to use IPFIREWALL compiled
170 into the kernel or as KLD.
173 The RANDOM_IP_ID option has been replaced by the sysctl
174 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
175 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
178 The size of 'struct ifnet' has changed due to the addition of the
179 if_carp placeholder. All kernel modules implementing network
180 interfaces must be recompiled as a result.
183 Module loading has been fixed. Some older installations will
184 drop proper module_path initialization and modules will fail to
185 load properly. If you have a line in /boot/loader.rc that says:
186 "initialize drop", do (i386 only):
187 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
188 chown root:wheel /boot/loader.rc
189 chmod 444 /boot/loader.rc
192 making /dev/(null|zero) into a module proved to be too unpopular,
193 so this bit has been revoked from the previous (20040801) entry.
196 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
197 so you may wish to add them to your kernel config file. See
198 GENERIC for examples.
201 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
202 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
203 has broken C++ ABI compatibility with previous releases yet again
204 and users will have to rebuild all their C++ programs with the new
205 compiler. If you are getting run-time error such as
206 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE"
207 This entry does apply to you.
209 A new unit-at-a-time optimization mode, which is default in this
210 compiler release, is more aggressive in removing unused static
211 symbols. This is the likely cause of 'make buildworld' breakages
212 with non-default CFLAGS where optimization level is set to -O2
215 With the upgrade of the system compiler, the kernel has been upgraded
216 to match the new system compiler. This makes it impossible to build
217 a new kernel with the old compiler. Upgrade your system via
218 make buildworld and make kernel (see below) to fix this problem.
221 The size of 'struct ifnet' has changed due to the addition of
222 the IFF_NEEDSGIANT flag (and what it implies). All kernel
223 modules implementing network interfaces must be recompiled as
227 The sound device drivers are renamed. `sound' is always required,
228 while `snd_*' should be configured accordingly to your hardware.
229 Refer to NOTES for the detail of the drivers.
232 __FreeBSD_version bumped to 502122.
235 The console initialization on Alpha has been reworked and is now
236 identical to other platforms. This means that the hardcoding of
237 the serial console and the debug port has been removed. As such,
238 hints are now required for the sio(4) driver to become a console
239 or debug port. The NO_SIO option has been decommissioned because
243 A revamp of the debugging code in the kernel with some visible
244 changes beyond just the debugging experience:
245 o The DDB option is now specific to the DDB debugger backend
246 and should not be used any more for conditional compilation
247 of debugging code for when debugging is enabled. Use the KDB
249 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
250 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
251 respectively. This is in line with the first bullet.
252 o The remote GDB support has been untangled from DDB and needs
253 to be enabled separately now. Use the GDB option for this.
254 o The GDB_REMOTE_CHAT option has been removed. Support for this
255 homegrown feature is discontinued. The GDB remote protocol
256 supports console output and it makes sense to use that.
257 o The DDB_NOKLDSYM option has been removed. The DDB debugger
258 now supports both direct symbol table lookups as well as KLD
259 symbol lookups through the linker.
262 Bluetooth code has been marked as non-i386 specific.
263 __FreeBSD_version has been bumped to 502121 to mark this change.
266 The native preemption has been added to the kernel scheduler.
267 There is some report that the ULE scheduler was broken in some
268 machines and we encourage users using the ULE scheduler either
269 stick with a known good kernel, or temporarily switch to the 4BSD
270 scheduler as a workaround.
273 The netgraph ABI version number has been incremented to indicate
274 an incompatible change in the ABI. Old netgraph nodes will refuse
275 to attach until recompiled. Netgraph now uses mbuf tags to move
276 metadata and this commit removes its home-grown metadata facility.
277 Nodes should just recompile, unless they use metadata, in which
278 case the changes are simple; the file ng_ksocket.c serves as an
279 example of such changes.
281 This also broke i4b, although the compile problem has been papered
285 ACPI has been updated to disable known-bad BIOS revisions. A message
286 will be printed on the console indicating that ACPI has been disabled
287 automatically and that the user should use a newer BIOS, if possible.
288 If you think ACPI does work on your system and want to override
289 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
293 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
294 separated now. It uses the newly created "_pflogd" user/group
295 combination. If you plan to use pflogd(8) make sure to run
296 mergemaster -p or install the "_pflogd" user and group manually.
299 Network interface cloning has been overhauled. This change will
300 require a recompile of modules using cloning and modification of
301 external ones to the new API. __FreeBSD_version has been bumped
302 to 502119 to mark this change. Additionally, users creating
303 stf(4) interfaces via "ifconfig stf" will need to update their
304 scripts as this will create an interface named "stf" instead of
305 "stf0" and ifconfig will not print "stf0" to stdout.
308 On 20040524, the /etc/rc.d/nsswitch script was modified to
309 automatically create /etc/nsswitch.conf on startup if it did
310 not already exist. Unfortunately, an error in the man page
311 was carried over to the script, resulting in incorrect
312 nsswitch settings. The simplest remedy is to remove both
313 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
314 during the next reboot.
317 The return value of sema_timedwait(9) has been changed to
318 make it consistent with cv_timedwait(9). Be sure to recompile
319 the ips module and any third-party modules which call
323 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
324 Make sure to recompile modules and any userland that makes use of
325 sizeof(struct ifnet). In order to get the altq headers in place
326 please recompile and reinstall world.
329 Splitting kern_thread.c into 2 files (adding kern_kse.c)
330 requires that you re-run config after updating your tree.
333 The MIDI drivers have been removed. Until the new module-friendly
334 ones are merged, remove or comment out midi and seq from your
335 kernel configuration.
338 Due to a new option in ipfw (versrcreach) the ipfw(8) command
339 needs to be recompiled. Normal accept/reject rules without
340 options are not affected but those with options may break until
341 ipfw(8) is recompiled.
344 Due to changes in the callout ABI, kernels compiled after this
345 date may be incompatible with kernel modules compiled prior to
349 The PCI bus power state stuff has been turned on. If this causes
350 problems for your system, please disable it using the tunable
351 hw.pci.do_powerstate=0.
354 The bulk of the pci problems have been fixed, although the floppy
355 drive is still broken.
358 A substantial update to the pci bus resource and power management
359 have been committed. Expect a bumpy ride for a few days until
360 the unanticipated problems have been resolved.
363 Due to changes in the the Yarrow initialization process,
364 /dev/random needs to be fed before operations requiring
365 temp files can succeed in single user mode. This includes
366 running "make installworld". /dev/random may be fed by running
367 "/etc/rc.d/initrandom start" or with 20040415 source by running
368 "/etc/rc.d/preseedrandom".
371 The debug.mpsafenet tunable controls whether the kernel Giant
372 lock is held across the lower levels of the network stack, and
373 by default is turned off. In the few days following 20040322,
374 the behavior of debug.mpsafenet will change such that this
375 tunable controls Giant over all levels of the network stack.
376 If you are currently setting debug.mpsafenet to 1, you should
377 set it back to 0 (the default) again during the change-over.
378 An additional note will be added to UPDATING when sufficient
379 locking is merged to permit this to take place.
382 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
383 64-bits. This is a very major incompatible change, so people
384 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
385 detailed instructions on how to make this upgrade. People
386 upgrading FreeBSD on other platforms can ignore this event.
389 The packet filter (pf) is now installed with the base system. Make
390 sure to run mergemaster -p before installworld to create required
391 user account ("proxy"). If you do not want to build pf with your
392 system you can use the NO_PF knob in make.conf.
393 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
394 pf system consists of the following three devices:
396 device pflog # optional
397 device pfsync # optional
400 If you are having trouble with the libc_r -> libpthread transition
401 (see the 20040130 entry), place the following lines at the top of
404 libc_r.so.5 libpthread.so.1
405 libc_r.so libpthread.so
407 This will cause all programs and libraries linked against libc_r
408 to use libpthread instead.
411 Some sshd configuration defaults have changed: protocol version 1
412 is no longer enabled by default, and password authentication is
413 disabled by default if PAM is enabled (which it is by default).
414 OpenSSH clients should not be affected by this; other clients may
415 have to be reconfigured, upgraded or replaced.
418 The ABIs defined in <resolv.h> and <netdb.h> have been updated
419 to support improved reentrancy. Multi-threaded programs that
420 reference the "_res" or "h_errno" symbols may experience some
421 problems if they are not recompiled. Single-threaded programs
422 should remain unaffected.
425 routed has been updated in the base system from the vendor
426 sources, routed v2.27, from rhyolite.com. This change means that
427 for users who use RIP's MD5 authentication feature, FreeBSD
428 -CURRENT's routed is now incompatible with previous versions
429 of FreeBSD; however it is now compatible with implementations
430 from Sun, Cisco and other vendors.
433 The tcpcb structure has changed and makes a recompile of libkvm
434 and related userland network utilities necessary.
437 The cdevsw structure has changed in two externally visible ways.
438 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
439 Second, the d_version field must be filled in with D_VERSION.
440 Drivers outside the tree will need to be updated.
443 The /etc/rc.d/ttys script has been removed. It is no longer
444 necessary since devfs has been mandatory for some time.
447 libkse has been renamed back to libpthread and is now the
448 default threads library. The gcc -pthread option has also
449 been changed to link to libpthread instead of libc_r. For
450 alpha and sparc64 machines, libkse is not renamed and links
451 are installed so that libpthread points to libc_r. Until
452 the ports system is updated to handle this change, it is
453 recommended that folks install an /etc/libmap.conf(5) that
454 maps libc_r to libpthread. If you have any binaries or
455 libraries linked to libkse, then it is also recommended
456 that you map libkse to libpthread. Anyone that is using
457 nvidia supplied drivers and libraries should use a libmap.conf
458 that maps libpthread to libc_r since their drivers/libraries
459 do not work with libpthread.
462 ULE has entered into its probationary period as the default scheduler
463 in GENERIC. For the average user, interactivity is reported to be
464 better in many cases. On SMP machines ULE will be able to make more
465 efficient use of the available parallel resources. If you are not
466 running it now, please switch over, replacing the kernel option
467 SCHED_4BSD with SCHED_ULE.
470 Move LongRun support out of identcpu.c, where it hardly
471 belongs, into its own file and make it opt-in, not mandatory,
472 depending on CPU_ENABLE_LONGRUN config(8) option.
475 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
476 if the login process is unable to successfully set the
477 process credentials to include all groups defined for the
478 user. The current kernel limit is 16 groups; administrators
479 may wish to check that users do not have over 16 groups
480 defined, or they will be unable to log in.
483 The ACPI module has been reactivated. It is no longer required
484 to compile ACPI support into kernels statically.
487 The statfs structure has been updated with 64-bit fields to
488 allow accurate reporting of multi-terabyte filesystem
489 sizes. You should build world, then build and boot the new kernel
490 BEFORE doing a `installworld' as the new kernel will know about
491 binaries using the old statfs structure, but an old kernel will
492 not know about the new system calls that support the new statfs
494 Note that the backwards compatibility is only present when the
495 kernel is configured with the COMPAT_FREEBSD4 option. Since
496 even /bin/sh will not run with a new kernel without said option
497 you're pretty much dead in the water without it. Make sure you
498 have COMPAT_FREEBSD4!
499 Running an old kernel after a `make world' will cause programs
500 such as `df' that do a statfs system call to fail with a bad
501 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
502 that cfsd (ports/security/cfs) needs to be recompiled after
503 these changes are installed.
505 ****************************DANGER*******************************
507 DO NOT make installworld after the buildworld w/o building and
508 installing a new kernel FIRST. You will be unable to build a
509 new kernel otherwise on a system with new binaries and an old
513 Some netgraph string length constants have been changed. This
514 change requires the netgraph kernel modules and all netgraph
515 userland components to be in sync. Especially users who require
516 netgraph to boot need to make sure to have world and kernel in
517 sync before rebooting.
520 Hyperthreading logical CPU's are no longer probed by default
521 when using the MP Table. If ACPI is being used, then logical
522 CPUs will be probed if hyperthreading is enabled in the BIOS.
523 If ACPI is not being used and hyperthreading is enabled in the
524 BIOS, logical CPUs can be enabled by building a custom kernel
525 with the option MPTABLE_FORCE_HTT enabled.
528 The i386 APIC_IO kernel option has been replaced by
529 'device apic'. The ACPI module has also been temporarily
530 disabled, so ACPI must be statically compiled into your
531 kernel using 'device acpi' if you wish to use the ACPI driver.
534 The API and ABI of struct ifnet have been changed by removing
535 the if_name and if_unit members and replacing them with
536 if_xname, if_dname, and if_dunit. All network drivers and most
537 userland programs which include net/if_var.h must be updated
538 and recompiled. __FreeBSD_version has been bumped to 501113 to
542 Changes to the cdevsw default functions have been made to remove
543 the need to specify nullopen() and nullclose() explicitly.
544 __FreeBSD_version bumped to 501110.
547 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
548 mount_cd9660(8) need to be in sync with kernel.
551 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
552 also be explicitly configured. Previously this dependency was
553 magically handled through some cruft in net/pfil.h; but that has
554 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
555 will fail with obtuse errors in ip_fil.c.
558 Fix a bug in arplookup(), whereby a hostile party on a locally
559 attached network could exhaust kernel memory, and cause a system
560 panic, by sending a flood of spoofed ARP requests. See
561 FreeBSD-SA-03:14.arp.
564 A change to /etc/defaults/rc.conf now causes inetd to be started
565 with `-C 60' if it is not overridden in /etc/rc.conf. This
566 causes inetd to stop accepting connections from an IP address
567 that exceeds the rate of 60 connections per minute.
570 The following rc.d scripts have been removed and should be
571 deleted from your installation: atm2.sh atm3.sh devdb
572 localdaemons network1 network2 network3. Depending on when
573 you last updated world and used mergemaster(8) you may or
574 may not have problems during the rc boot sequence. The simplest
575 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
576 The atm2.sh atm3.sh and devdb scripts were removed some time
577 ago, so depending on when you installed -CURRENT these scripts
578 may or may not exist on your system.
581 ATAng has been committed. You need to build world as sys/ata.h
582 has changed, and userland atacontrol depends on it.
583 If you use ATA SW raids you need "device ataraid" in your
584 kernel config file, as it is no longer pulled in automatically.
587 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
588 Among other things, this changes the device enumeration to be
589 closer to Solaris. Be aware that, this can even cause the machine
590 to not boot without manual intervention before the fstab is adjusted.
593 All current USB and Firewire quirks in da(4) have been deprecated
594 and will be removed for 5.2. If this causes failure for your
595 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
596 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
597 so the quirk can be re-enabled.
600 Problems with entry 20030714 have been corrected and no known issues
601 with /rescue and -j exist for host systems after this point in time.
604 FPU-less support has been removed from FreeBSD. Chances are you won't
605 notice. 386+387 support should still work after this change, but
606 it is now a minimum requirement for the i386 port that you have real
610 Some people are having problems with changes related to /rescue.
611 If you are building -j N, you will need to define NO_RESCUE. Others
612 will need to define it if /rescue has issues with their environment.
613 People should report those issues to current@.
616 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
617 across this point. Further, it might be a good idea to remove
621 Remove deprecated locale names and transition period code
622 for them, finishing switching to the new scheme. Check your
623 LANG environment variable.
626 CCD has been changed to be a fully GEOMified class. Kernel
627 and ccdconfig(8) needs to be in sync, this is particularly
628 important to remember beforehand if your source tree is on
629 a ccd device. Consider making a copy of the old ccdconfig
630 into /boot/kernel.good or wherever you keep your backup
634 There was a small window in which sed(1) was broken. If you
635 happen to have sed(1) installed during that window, which is
636 evidenced by an inability to build world with the failure
637 given below, you need to manually build and install sed(1)
638 (and only sed(1)) before doing anything else. This is a one-
639 time snafu. Typical failure mode:
641 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
642 targmatch.h:7:1: null character(s) ignored
643 targmatch.h:12:1: null character(s) ignored
644 targmatch.h:16:1: null character(s) ignored
647 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
648 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
649 usr.bin/sed/process.c).
652 Kerberos 5 (Heimdal) is now built by default. Setting
653 MAKE_KERBEROS5 no longer has any effect. If you do NOT
654 want the "base" Kerberos 5, you need to set NO_KERBEROS.
657 groff has been updated. If you try to do a buildworld and
658 get an infinite loop in troff, update to May 4th or newer. If you
659 have a newer kernel than userland, you may need to set the OSRELDATE
660 to 500110 in your environment before starting a buildworld.
663 The old rc system has been removed. Please report any problems
664 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
665 Your personal versions of these files will not be removed, so you can
666 continue to use them. However, you should take great care when updating,
667 especially when using mergemaster, since the compatibility code that
668 utilizes these old scripts has also been removed.
671 A bug has been fixed in /dev/devctl which would cause devd
672 to hang on boot, were it not for a workaround in devd. The
673 work around in devd will be removed around 20030507. You
674 have until then to upgrade your kernel before updating
675 userland. In general, you should have a userland and
676 kernel that's in sync with each other. However, given the
677 effects of this bug (hang on boot when starting devd), some
681 Alphas with libc from between 20030312 and 20030329 exhibit
682 floating point exceptions (FPEs), most notably in awk(1)
683 while upgrading the system through a buildworld.
685 So, to successfully upgrade your Alpha, you must either
686 downgrade your libc.so to a pre-20030312 version, or update
687 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
688 to CFLAGS, then forcibly rebuild and install libc:
690 cd /usr/src/lib/libc && \
691 make cleandir && make obj && \
692 make -DNOMAN -DNOPROFILE all && \
693 make -DNOMAN -DNOPROFILE install
696 sendmail 8.12.7 has been imported. It has one important
697 change for IPv6 users. The default submit.mc now uses
698 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
699 used to connect to the MTA. Users on IPv6-only machines
700 will need to edit /etc/mail/submit.mc appropriately.
703 NODEVFS option has been removed and DEVFS thereby made standard.
704 This makes all references to MAKEDEV obsolete, and they should
705 be removed when convenient.
708 The name of the device for the ofw console has changed, sparc64 users
709 must run mergemaster to update their installed /etc/ttys.
712 The scheduler framework has grown a second scheduler and consequently
713 you must specify one and only one scheduler in your kernel config.
714 The cvs config files have been updated to use the old scheduler
715 which may be selected via 'options SCHED_4BSD'. If you would like
716 to try the new, much more experimental, scheduler please try
717 'options SCHED_ULE' and contribute to the arch@ discussion.
720 A new version of the wi driver has been imported into the tree.
721 One now must have device wlan in the config file for it to operate
724 In addition, there have been some changes to how wi devices are
725 configured for point to point links to bring it more in line
726 with the former way of doing things, as well as compatibility
730 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
731 used an incompatible form of ABI for returning structures and unions
732 which FreeBSD's GCC maintainers were not aware of relative to previous
733 versions of FreeBSD. We have gone back to the ABI for now, and any
734 code compiled which is required to interoperate with other code (not
735 built at the same time) returning structs or unions should be
739 A name change in /etc/netconfig has been reverted to stay
740 compatible with suns TIRPC and also with NetBSD. You need
741 to run mergemaster after make world. A new libc does still work
742 with an outdated /etc/netconfig for some time, but you'll get
743 a warning. This warning will be removed in 20030301.
746 The recent binutils upgrade marks a kernel flag day on
747 sparc64: modules built with the old binutils will not work
748 with new kernels and vice versa. Mismatches will result in
749 panics. Make sure your kernel and modules are in sync.
752 The value of IPPROTO_DIVERT has changed. Make sure to keep
753 your kernel, netstat, natd and any third-party DIVERT
757 Old, compatibility slices have been removed in GEOM kernels.
758 This means that you will have to update your /etc/fstab to
759 not use disk devices of the form /dev/ad0a. Instead, you
760 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
761 partition really is on. The old device names have gone
762 away, so if you use them anywhere else, you must also adjust
763 those uses. (This doesn't affect the disks formatted in
764 the ``dangerously-dedicated'' mode.)
767 Alphas with kernels from between 20020830 and 20021023 and/or
768 rtld (ld-elf.so.1) older than 20021023 may experience problems
769 with groff while doing a buildworld (kernel: "out of memory",
770 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
771 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
773 So, to successfully upgrade your Alpha, you must either
774 upgrade your kernel and rtld first (which might be a bit
775 tricky), or avoid running the bootstrapped groff during the
776 "transitional" buildworld. To avoid running groff during the
777 transitional upgrade run make buildworld with -DNOMAN,
778 -DNO_SHAREDOCS, and -DNO_LPR.
781 gcc has been upgraded to 3.2. It is not all binary compatible
782 with earlier versions of gcc for c++ programs. All c++
783 programs and libraries need to be recompiled.
785 Also, if you encounter g++ issues, rm /usr/include/g++/* before
786 doing an installworld to make sure that stale files are removed.
789 Our /etc/termcap now has all the entries from the XFree86 xterm
790 almost unchanged. This means xterm now supports color by default.
791 If you used TERM=xterm-color in the past you now should use
792 TERM=xterm. (xterm-color will lead to benign warnings).
795 A "bug" in gcc(1) that was hiding warning in system headers was
796 fixed. It's probably time to add -DNO_WERROR to your make line
800 COPY is being deprecated. The 20010530 change was reverted, as
801 it causes far more pain than was expected, and to always compare
802 before installing, please use INSTALL="install -C" again. The
803 -C option is now silently ignored when used with the -d option.
806 Problems with libc_r clients like KDE and GNOME have been resolved.
807 There are still some minor problems with some signals but the
808 system is stable enough for general use again. SMP is less so than UP
809 but each can successfully complete multiple buildworlds.
810 Libkvm needs to be recompiled due to KSE.
813 Now would be a bad time to upgrade. Something in or near the
814 KSE commit totally broke programs using libc_r like KDE and
818 The k5su utility installed as part of Kerberos 5 is no longer
819 installed with the set-user-ID bit set by default. Add
820 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
821 with the set-user-ID bit set.
824 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
825 Unfortunately our native GDB (at version 4.18) does not understand
826 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
827 generated debugging information for our native GDB.
830 Due to the way CVS works, it may not properly update src/contrib/gcc
831 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
832 and then do a cvs update.
835 When exec'ing set[ug]id executables, the kernel now ensures that the
836 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
839 New sendmail startup scripts have been installed to make it
840 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
841 variable sendmail_enable to "NO" no longer prevents any sendmail
842 daemons from starting. Instead, either set sendmail_enable to
843 "NONE" or change mta_start_script to a script for starting
844 an alternative MTA. Setting mta_start_script to "" will
845 also prevent any MTA from being started at boot.
848 UCONSOLE is no longer a valid kernel option.
851 FreeBSD 5.0 DP-1 was basically branched today.
854 Warnings are now errors in the kernel. Unless you are a developer,
855 you should add -DNO_WERROR to your make line.
858 sendmail 8.12.2 has been imported. The sendmail binary is no
859 longer a set-user-ID root binary and the infrastructure to support
860 command line mail submission has changed. Be sure to run
861 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
862 and /etc/mail) and read /etc/mail/README for more details.
864 Due to the import of sendmail 8.12.2, a new user and group are
865 required in order for sendmail to run as a set-group-ID
866 binary. A 'make installworld' will use the new user and group
867 to set the owner and group of /var/spool/clientmqueue and will
868 fail if the new user and group do not exist. The 'smmsp' user
869 and group must be merged from src/etc/group and
870 src/etc/master.passwd before using 'make installworld'.
871 'mergemaster -p' will do this. You may need to install
872 mergemaster before this will work if you are updating from a
873 very old version of current. The updating recipe has changed
877 The preferred configuration method for PAM is now /etc/pam.d/
878 rather than /etc/pam.conf. If you have an unmodified
879 pam.conf, just delete it after your next mergemaster run. If
880 you have local modifications, you can use
881 /usr/src/etc/pam.d/convert.pl to incorporate them into your

892 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
893 started out its life in the ISDN4BSD project as an offspring
894 from sys/net/if_spppsubr.c, which eventually got a life of its
895 own. All the accumulated features and bug fixes of the i4b
896 version have now been merged back into the base system's
897 version now. The only user-visible change resulting from this
898 is that i4b's sppp(4) interfaces are to be managed with
899 spppcontrol(8) again, since ispppcontrol(8) has been retired
900 as well. (There has never been rc file support for
901 ispppcontrol in -current, but only in -stable. That will be
902 reverted by the time the changes are MFCed.)
905 The fdc(4) driver has been updated and now automatically
906 recognizes media in `standard' formats (like 1440 KB and
907 720 KB for a 3.5" high-density drive) when accessing the
908 default device node (e. g. /dev/fd0). The old variety of
909 floppy device nodes /dev/fd*.* is no longer present by
910 default, devices can be created (in DEVFS) on demand. They
911 will need to be customized then for `odd' densities using
915 The bugs in procfs' debugging support code have been fixed,
916 and truss(1) now works again.
919 Daily security checks have been split out to use the periodic(8)
920 scripts. Some change in configuration may be necessary. Please
922 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
926 sos added VCD/SVCD support to ata driver and that needs the
927 kernel and burncd to be in sync.
930 The procfs pseudo-filesystem has now been converted to use the
931 pseudofs framework. If you have 'options PROCFS' in your
932 kernel config, you'll need to add 'options PSEUDOFS' if it's
935 This change temporarily breaks truss(1); use ktrace(1) instead
936 until the issue has been resolved.
939 A security hole in OpenSSH involving `UseLogin yes' has been
943 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
944 after this date. You need to do this only once.
947 Most of the awk issues have been resolved. Some rough
948 edges may be left, but for the most part things should be
949 back to "normal." For CURRENT's usual definition of "normal."
952 Awk has been upgraded to the one true awk from bell labs. Expect
953 choppy waves in the upgrade process.
956 The asr driver problem has been resolved.
959 Due to changes in other parts of the system, the asr driver
960 now causes the system to panic on boot. Do not use it pending
961 correction. Comment it out of any kernel config file that you
962 try to use from this date forward.
965 When crossbuilding, use TARGET=xxx where you used to use
966 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
967 unless you are changing both of them. To cross build pc98 on
968 an alpha, for example, you need to set TARGET=pc98 and
972 The kernel interface that burncd depends on has changed.
973 You must recompile both the kernel and userland applications
977 When crossbuilding, please set TARGET_ARCH rather than
978 MACHINE_ARCH to indicate the target. In the future, one will
979 set TARGET_MACHINE where you set MACHINE now. At the moment,
980 setting MACHINE alone for same MACHINE_ARCH machines works
981 (eg, you can build pc98 on an i386 machine and vice versa).
984 Some weird problems result from using ACPI on some machines.
985 To disable ACPI you can add
986 hint.acpi.0.disabled="1"
987 to /boot/loader.conf (or by putting set X=Y at the boot
990 Alternatively, you can remove it from /boot/kernel/acpi.ko
991 or use the MODULES_OVERRIDE function in your kernel config
992 file and not list acpi in that list.
995 The buildworld has been fixed. You may need to install
996 the 4.x compatibility libraries for some old binaries
997 to work. Add COMPAT4X=true to your /etc/make.conf to
998 get them installed on every installworld, or execute the
999 following to get them installed only once:
1000 cd src/lib/compat/compat4x.<arch>
1002 You will see ``__stdoutp undefined'' until you do this.
1005 There's a bug in the world build process. The cross-tools
1006 are build with the NEW headers, but the OLD libc.a. This
1007 leads to all kinds of problems with the new libc. A temporary
1008 workaround is to add
1009 CFLAGS="-O -pipe -D_OLD_STDIO"
1010 before building world when upgrading from 4.x to current. This
1011 can be removed afterwards.
1013 A proper fix to the buildworld target is needed.
1016 Peter has committed his new kthread nfs client/server code.
1017 NFS may be unstable after this date.
1020 KSE has hit the tree. Lots of things are now different in
1021 the kernel. While a few problems were introduced in the
1022 initial commit, most of the major ones have been found and
1026 In OLDCARD, CardBus bridges appear to be stable. The work
1027 arounds described in the 20010604 entry are now no longer
1028 necessary and will be ignored. Most insert/remove problems
1029 have been rectified around this date.
1032 named now runs as user bind and group bind rather than as
1033 root. If named_enable is set to YES in /etc/rc.conf, ensure
1034 that user bind is available in /etc/passwd (using vipw(8))
1035 and that group bind is available in /etc/group. Also make
1036 sure that user or group bind has read (and not write)
1037 permission for your name server configuration and that it
1038 has read and write permission for your slave zone files and
1041 If you wish to continue to run named as root (a less secure
1042 alternative), add a line to /etc/rc.conf saying
1047 The PAM libraries have had an API upgrade that is beyond
1048 the ability of the shared library major number to handle.
1049 It is manifested by PAM-using ports dumping core. The
1050 solution is to rebuild those ports.
1053 The kernel compile module has moved from src/sys/compile/FOO
1054 to src/sys/${MACHINE}/compile/FOO.
1057 The pccard modem issue from 20010613 has been corrected.
1058 OLDCARD support is still a little weak in -current. slot 1 is
1059 known not to work on some TI based cardbus bridges. Some
1060 cardbus bridges do not properly detect insert/removal events.
1061 IRQ configuration needs more safety belts.
1064 Softupdates problems have been corrected.
1067 Peter ripped out the linkerset support. You must, as always,
1068 rerun config after you cvsup if you are using the traditional
1069 kernel building methods.
1072 pccard modems may not work with current after 20010604 date. Some
1073 do, others result in panics. *MAKE*SURE* that you update your
1074 config and /etc/rc.conf ala the 20010604 entry, or you will have
1075 problems (this issue will be fixed, it just hasn't been yet).
1078 SOFTUPDATES seem to be broken since the middle of May or so. Do not
1079 use them in current. You can disable softupdates on all mounted
1080 partitions, or remove SOFTUPDATES the kernel config file.
1083 After Peter's commits to the hints code, people have been noticing
1084 that certain devices are attached (or try to) twice. This is due
1085 to having both static hints as well as a /boot/device.hints. To
1086 work around this issue, please use only one or the other mechanism
1087 until this bug is fixed.
1089 Please note that a feature of config is that if you have config
1090 file FOO and FOO.hints, it automatically adds FOO.hints to the
1091 hints.c file, whether you want it to or not.
1094 Locale names have changed to match other systems better.
1097 pccard support for pci cards has been committed. You must change
1098 your /etc/pccard.conf irq lines. It must match the irq used by
1099 pcic device. Interrupt storms may result if you fail to do this.
1100 Interrupt storms look a lot like a hang.
1102 You must also install a new pccardd, otherwise you will get an
1103 interrupt storm at card reset time (just after it tells you what
1106 pccardd_flags="-I" is necessary for the time being. It tells pccardd
1107 not to ask the kernel if the interrupt is really free or not before
1108 using it. You can either change the /etc/pccard.conf irq lines to
1109 match pcic, or add "-i X" to the pccardd_flags.
1112 INSTALL=install -C is being deprecated. If you want to do this,
1113 use COPY=-C instead. The former method will be supported for only
1114 a limited time. If you see
1116 install: warning: the -d and -C options may not be specified together
1118 in your makeworld, then you need to migrate towards using
1122 It appears that vm is now stable enough to use again. However,
1123 there may be other problems, so caution is still urged. alpha
1124 definitely is in bad shape.
1127 Minor repo damage has happened. This may cause problems
1128 with cvsup of ports. If you get errors, please see
1129 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
1130 at the bottom for details on a workaround. The error message
1132 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
1135 Vm and/or swapping are busted on -current. Please be patient.
1138 pccard has had much reorganizational work done to it over
1139 the past few days. Everything should still work, but if
1140 not, please contact imp@freebsd.org.
1143 ata ioctl changed. Make sure to recompile both kernel and
1144 userland at the same time.
1147 New ncurses imported.
1150 DEVFS is now opt out, not opt in. Barring major problems, this
1151 will be the only way to go starting July 1.
1154 OpenSSH has been updated to 2.9. Some defaults are different,
1155 including RhostsRSAAuthentication, which changes from yes to no.
1158 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
1161 Building perl was broken at 02:25:25 PDT.
1164 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
1165 go back in the water.
1168 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
1169 this date, but before the correction date.
1172 old fsck and new kernel interactions appear to have been fixed.
1175 fsck and the kernel were changed to handle some optimizations
1176 to directory layout. This breaks backward compatibility.
1177 Update only if you understand that you must not use the old
1178 fsck with the new kernel ever.
1181 fsck has changed the meaning of the pass column in /etc/fstab.
1182 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1183 details. It is unclear if changes to /etc/fstab are necessary.
1186 portmap had changed name to rpcbind for maximum POLA in your
1187 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1188 other rpc based programs that rely on portmapper will not work
1189 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1192 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1193 and ATA_ENABLE_TAGS are no longer kernel options. They have
1194 been replaced by tunables. See ata.4 for details.
1197 The fxp driver was converted to use miibus. If you compile
1198 fxp into your kernel statically, you will need to add miibus.
1201 The wi device now defaults to BSS (infrastructure) mode
1205 /dev/urandom should be a symbolic link to /dev/random now.
1206 Users of current not using DEVFS need to run MAKEDEV std.
1207 ssh might not work if you don't.
1210 The ed driver has been updated. It now allows mii attachments,
1211 which means that you must include the miibus in your kernel if
1212 you use the ed driver.
1215 The problems with libc have been corrected. It is now mostly
1216 safe to go back into the water.
1219 The size of FILE was changed. This breaks upgrading. If
1220 you must upgrade, be prepared for pain. It also breaks almost
1221 all binaries that you've compiled on -current. You are warned
1222 that before upgrading would be a good time to do a level 0
1223 dump of your system. No, really, I mean it this time.
1225 To get to the new system, you'll need to use the following
1226 workaround. Hopefully this can be sorted out so that we
1227 don't have to move this to the updating section.
1229 To get around the installworld problem, do:
1230 # cd /usr/src/usr.bin/sed
1234 If that doesn't work, then try:
1235 # make -k installworld
1239 DEVFS is now the default. If you use vinum, make sure that you
1240 do not include devfs in your kernel as problems result.
1243 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1244 Remove them from your config.
1247 ****************************** WARNING ******************************
1248 buildkernel has been changed slightly

1250 KERNCONF replaces the variable KERNEL for buildkernel. You

1254 config has changed to allow DEV_FOO as a replacement for NFOO.
1255 This requires a new config to build correctly.
1258 The kernel option I386_CPU is now mutually exclusive with the
1259 other cpu types. If you have an i386 system, be sure that it
1260 only had this line. Remove it for all other configurations.
1263 Changes to the kernel require it and burncd be in sync.
1266 Everyone who has hw.sndunit set to something in
1267 /etc/sysctl.conf, it is now hw.snd.unit.
1270 ex and vi were broken by some changes to sys/queue.h. If you
1271 have a bad vi, you will see make buildworld fail with a core
1272 dump while building termcap. You can work around this problem
1273 by adding -k to your make buildworld. This will cause the
1274 build to complete and install a new vi. Once that's done, you
1275 can rebuild again without the -k to pick up anything that
1276 might have been ignored by the -k option.
1278 Others have suggested that you can just rebuild libc if your
1279 vi/ex is dynamically linked, but I've not received any reports
1283 There have been some changes to libcrypt in -current. The
1284 libscrypt/libdescrypt symlink silliness is gone and the installed
1285 libcrypt is fully functional. Be aware of this.
1288 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1289 now require the addition of flag 0x80000 to their config line
1290 in pccard.conf(5). This flag is not optional. These Linksys
1291 cards will not be recognized without it.
1294 Important new FreeBSD-version stuff: PAM support has been worked
1295 in, partially from the "Unix" OpenSSH version. This requires
1296 adding the following in pam.conf:
1298 sshd auth sufficient pam_skey.so
1299 sshd auth required pam_unix.so try_first_pass
1300 sshd session required pam_permit.so
1303 cvs updated to 1.11.
1306 The random device needs more entropy, so you need to make sure
1307 that you've run mergemaster to get a /etc/rc which will seed
1308 /dev/random. If you don't and the system hangs after ldconfig,
1309 then banging on the keyboard randomly until it unhangs is one

1330 The ports tree's new layout is in place. Be sure to update
1331 your entire ports tree, or you will have problems.
1334 The perl build procedure no longer installs miniperl, nor uses
1335 the installed miniperl. It is recommended that you delete
1339 This weekend the ports tree will be updated to a new layout.
1340 It will be in an inconsistent state until noted in the UPDATING
1341 file, or with asami-san's message to the relevant mailing
1342 lists. With this new layout, you'll need to update the whole
1343 tree for anything to work.
1346 There was a change in the passwd format. Need more information.
1349 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1350 place. Please update boot loader (not the boot blocks) at the
1351 same time as your kernel.
1354 The new pmtimer device is necessary for laptops. Failure to
1355 include the device will cause suspended laptops losing time
1356 when they resume. Include
1358 in your config file and
1359 hint.pmtimer.0.at="isa"
1360 to your /boot/device.hints file.
1363 The random device has been turned into a (pseudo-)device,
1364 rather than an option. The supplied kernel config files have
1365 been updated. You will need to do something similar in your
1366 own kernel config file.
1371 If you prefer to load the loadable module, you need to do
1375 The random device module has been renamed from randomdev.ko to
1376 random.ko. You will need to edit your /boot/loader.conf to
1377 reflect this if you load this module at boot time.
1378 The line should read:
1382 The SMPNG commit has happened. It should work, but if it
1383 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1384 to be a variety of minor issues. Please see 20000905 to make
1385 sure you don't have model loading problems which might at
1386 first blush appear related to SMP.
1389 nsswitch has been imported from NetBSD. Among other things,
1390 this means that /etc/host.conf is no longer used. See
1391 nsswitch.conf(5) instead. Note that at boot time rc.network
1392 will attempt to produce a new nsswitch.conf file for you if you
1393 don't have one, and you have host.conf.
1396 The ucred structure changed size. This breaks the interface
1397 that mountd uses. Trying to use an older mountd with a newer
1398 kernel guarantees a panic. This means that you need to use
1399 kernels newer than today only with matching mountd, but you
1400 needed to do that anyway with the boot loader changes.
1403 The boot loader has been updated. The new default kernel is
1404 now /boot/kernel/kernel.ko. The new default module location
1407 You *MUST* upgrade your boot loader and kernel at the same time.
1408 The easiest way to do this is to do the buildworld/buildkernel/
1409 installkernel/installworld dance.
1411 Furthermore, you are urged to delete your old /modules directory
1412 before booting the new kernel, since kldload will find stale
1413 modules in that directory instead of finding them in the correct
1414 path, /boot/kernel. The most common complaint that this cures
1415 is that the linux module crashes your machine after the update.
1417 if [ ! -d /boot/kernel.old ]; then
1418 mv /modules.old /boot/kernel.old
1419 chflags noschg /kernel.old
1420 mv /kernel.old /boot/kernel.old/kernel.ko
1421 chflags schg /boot/kernel.old/kernel.ko
1425 A new issue with the sendmail upgrade has come to light.
1426 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1427 incorrectly install the default aliases in /etc/mail rather than
1428 move the old one from /etc. So you'll need to manually move the
1429 file, create a symbolic link, remove the old /etc/aliases.db and
1430 run newaliases. For safety sake, you should stop sendmail
1431 while doing this and run the upgrade when locally sourced email
1432 is not likely to be generated.
1435 /boot/device.hints is now required for installkernel to
1436 succeed. You should copy GENERIC.hints for your architecture
1437 into /boot/device.hints. If and only if you compile hints
1438 into your kernel, then this file may be empty. Please note,
1439 if you have an empty or missing /boot/device.hints file and
1440 you neglected to compile hints into your kernel, no boot
1441 messages will appear after the boot loader tries to start the
1445 If you do NOT have ``options RANDOMDEV'' in your kernel and
1446 you DO want the random device then add randomdev_load="YES" to
1450 suidperl is now always built and installed on the system, but
1451 with permissions of 511. If you have applications that use
1452 this program, you are now required to add ENABLE_SUIDPERL=true
1453 to /etc/make.conf. If you forget to do this,
1454 chmod 4511 /usr/bin/suidperl
1455 will fix this until the next build.
1458 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1459 visible changes that may immediately affect your configuration
1461 - New default file locations from src/contrib/sendmail/cf/README
1462 - newaliases limited to root and trusted users
1463 - MSA port (587) turned on by default
1464 - New queue file naming system so can't go from 8.11 -> 8.9
1465 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1466 - FEATURE(`nullclient') is more full featured
1467 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1468 - mail.local FreeBSD-only -b option changed to -B
1469 - See src/contrib/sendmail/RELEASE_NOTES for more info
1472 suidperl (aka sperl) is no longer build by default. You must
1473 specifically define BUILD_SUIDPERL to "true" for it to be build.
1474 Furthermore, we recommend that you remove /usr/bin/sperl* and
1475 /usr/bin/suidperl files from your system unless you have a
1476 specific use for it.
1479 Networking defaults have been tightened. Anybody upgrading
1480 /etc/defaults/rc.conf needs to add the following lines to
1481 /etc/rc.conf if they want to have the same setup
1482 afterwards (unless the variables already are set, of course):
1483 # Enable network daemons for user convenience.
1485 portmap_enable="YES"
1486 sendmail_enable="YES"
1489 If you have null_load="YES" in your /boot/loader.conf, you
1490 will need to change that to nullfs_load="YES".
1493 The "installkernel" target has changed slightly. Now even if
1494 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1495 it will install the MYKERNEL file (built with the buildkernel
1496 target) as /kernel rather than /MYKERNEL. Those who have
1497 updated their /boot/loader.conf files to point to /MYKERNEL
1498 should remove that entry or perform manual rename of /kernel
1502 If you use CVSUP or CTM to get CVS trees, AND you used to get
1503 the old crypto files from internat.freebsd.org AND you check
1504 out files from the CVS tree with the cvs command, please read
1505 http://people.freebsd.org/~imp/internat.txt
1506 for details on potential problems that you might have and how
1509 If you are merely a mirror, or don't answer yes to each of the
1510 clauses above, you needn't worry.
1513 /etc/security has been updated to print the inode number of
1514 setuid programs that have changed. You will see a large spike
1515 in the number of changed programs the first time when you run
1516 mergemaster to get a new /etc/security.
1519 /dev/random now has good entropy collection (from the keyboard
1520 and sysmouse drivers). Please ensure that either `options
1521 RANDOMDEV' is present in your kernel config file or that
1522 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1523 not have the /dev/random driver, OpenSSL (and consequently
1524 lots of crypto tools (like SSH)) will fail with strange
1525 errors. (see below, 20000624).
1527 FreeBSD-current is safe again to run Crypto.
1530 phk made the malloc default options AJ. This may slow things
1531 down and uncover other latent bugs in the code. If you need to
1532 run at full speed, you can disable this by doing the following:
1533 ln -s aj /etc/malloc.conf
1536 libftpio's version was accidentally bumped a few days ago. This
1537 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1538 before doing your next buildworld/installworld pair. It certainly
1539 won't hurt to remove it before the update procedure. It will
1540 break fetch until a new one is built, but ftp can be used in the
1544 The crypto packages have changed for the cvsup. This has been done
1545 in a backward compatible way, but the old packages will go away at
1546 some point in the future. Look at /usr/share/examples/cvsup for
1550 With the new sys/modules/sound/drivers/*, you will need to
1551 set SYSDIR until you do an installworld after July 7th.
1554 rc.shutdown and rc will now call the rc.d scripts with start
1555 or stop. This may cause some harmless warnings from older
1556 rc.d scripts that haven't been updated.
1559 The libfetch based version of fetch has gone into the tree.
1560 Minor problems may result on some of the less popular sites,
1561 which should be reported to des@freebsd.org.
1564 From approximately this date forward, one must have the crypto
1565 system installed in order to build the system and kernel.
1566 While not technically strictly true, one should treat it as
1567 required and grab the crypto bits. If you are grabbing CVS
1568 trees, src-all and cvs-crypto should be treated as if they
1569 were required. You should check with the latest collections
1570 to make sure that these haven't changed.
1573 Mark Murray just committed the first parts of a cleanup of
1574 /dev/zero, et al. This is also cleaning up /dev/random.
1575 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1576 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1577 until Mark can merge in the fixes to this work in progress.
1578 openssh and openssl should not be used to generate keys from this
1579 date to the completion of the work.
1581 If you must operate at this reduced level of security, add '
1582 options RANDOMDEV' to your kernel or modload the randomdev
1583 module. You may also need to copy a new MAKEDEV to /dev and
1584 recreate the random and urandom devices.
1587 The license on the softupdates is now a standard 2 clause
1588 BSD license. You may need to remove your symbolic links
1589 that used to be required when updating.
1592 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1593 the config file update procedure.
1594 http://people.freebsd.org/~imp/config-upd.html
1595 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1596 isn't buildable. However, you can generate a LINT file:
1597 cd /sys/<ARCH>/conf && make LINT
1600 Binutils 2.10 have hit the tree, or will shortly. As soon
1601 as they do, the problem noted in 20000522 will be resolved and
1602 that workaround will no longer be required.
1605 phk removed the compatibility creation of wd devices in the
1606 ad driver. If you haven't done so already, you must update
1607 your fstab, etc to use the ad devices instead of the wd
1610 In addition, you'll need to update your boot blocks to a
1611 more modern version, if you haven't already done so. Modern
1612 here means 4.0 release or newer (although older releases
1616 Peter took an axe to config(8). Be sure that you read his mail
1617 on the topic before even thinking about updating. You will
1618 need to create a /boot/device.hints or add a hints directive
1619 to your config file to compile them in statically. The format
1620 of the config file has changed as well. Please see GENERIC or
1621 NEWCARD for examples of the new format.
1623 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1624 says that it has been fixed, assume that must use the hints mechanism
1625 in the loader if you need to use a machine with very old ISA cards
1629 A new set of binutils went into the tree today. Anybody
1630 building a kernel after this point is advised that they need
1631 to rebuild their binutils (or better yet do a
1632 buildworld/installworld) before building a new kernel.
1634 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1635 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1636 is recommended that you don't set this option until the problem
1640 The ethernet drivers were all updated to clean up the BPF handling.
1643 The problems with boot blocks on the alphas have been corrected.
1644 This will require some care in updating alphas. A new libstand
1645 is requires for the boot blocks to build properly.
1648 Recompile all kld modules. Proper version dependency info
1652 Modules have been disconnected from the buildworld tree and
1653 connected to the kernel building instead.
1656 You may need to build gperf
1657 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1658 when upgrading from 4.0 -> current. The build system now uses
1659 an option only in -current.
1662 The method that we brand ELF binaries has changed to be more
1663 acceptable to the binutils maintainers. You will need to
1664 rebrand your ELF binaries that aren't native. One problem
1665 binary is the Linux ldconfig. After your make world, but
1666 before you reboot, you'll need to issue:
1667 brandelf -t Linux /compat/linux/sbin/ldconfig
1668 if you have Linux compatibility enabled on your machine.
1671 If you have really bad/marginal IDE drives, you may find they
1672 don't work well. Use pio mode instead. The easiest way to
1673 cope if you have a problem combination is to add:
1674 /sbin/sysctl hw.ata.ata_dma=0
1675 to the start of /etc/rc.conf.
1678 The ISA and PCI compatibility shims have been connected to the
1679 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1680 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1681 include the appropriate option in your kernel config. Drivers
1682 using the shims should be updated or they won't ship with
1683 5.0-RELEASE, targeted for 2001.
1686 We've entered the traditional post release dumping party.
1687 Large kernel changes are being committed and are in the
1688 works. It is important to keep the systems' klds and kernel
1689 in sync as kernel interfaces and structures are changing.
1690 Before reporting kernel panics, make sure that all modules
1691 that you are loading are up to date.
1694 If you are upgrading from an older version of FreeBSD, you
1695 need to update your boot blocks as well. 'disklabel -B ad0'
1696 will do the trick. This isn't critical until you remove your
1697 wd device entries in /dev, at which point your system will not
1701 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1702 to upgrade to 4.0 from 3.x.
1706 # NOTE: 5.x below applies to 6.0-currrent as well, for the
1707 # momemnt. 4.any -> 5.any upgrade support will remain in
1708 # place for 6.0 current, but after 5.3 RELEASE, the 4.any ->
1709 # 6.0-current upgrade path will require moving through 5.3
1714 Avoid using make -j when upgrading. From time to time in the
1715 past there have been problems using -j with buildworld and/or
1716 installworld. This is especially true when upgrading between
1717 "distant" versions (eg one that cross a major release boundary
1718 or several minor releases, or when several months have passed
1719 on the -current branch).
1721 Sometimes, obscure build problems are the result of environment
1722 poisoning. This can happen because the make utility reads its
1723 environment when searching for values for global variables.
1724 To run your build attempts in an "environmental clean room",
1725 prefix all make commands with 'env -i '. See the env(1) manual
1726 page for more details.
1730 If you are updating from a prior version of FreeBSD (even one just
1731 a few days old), you should follow this procedure. With a
1732 /usr/obj tree with a fresh buildworld,
1733 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1734 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1736 To just build a kernel when you know that it won't mess you up
1737 --------------------------------------------------------------
1738 This assumes you are already running a 5.X system. Replace
1739 ${arch} with the architecture of your machine (e.g. "i386",
1740 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1742 cd src/sys/${arch}/conf
1743 config KERNEL_NAME_HERE
1744 cd ../compile/KERNEL_NAME_HERE
1749 If this fails, go to the "To build a kernel" section.

1797 # 5.x uses more space than 4.x. Also, the location of kernel
1798 # modules has changed. If you are installing 5.x onto a 4.x

1821 Make sure that you've read the UPDATING file to understand the
1822 tweaks to various things you need. At this point in the life
1823 cycle of current, things change often and you are on your own
1824 to cope. The defaults can also change, so please read ALL of
1825 the UPDATING entries.
1827 Also, if you are tracking -current, you must be subscribed to
1828 freebsd-current@freebsd.org. Make sure that before you update
1829 your sources that you have read and understood all the recent
1830 messages there. If in doubt, please track -stable which has
1831 much fewer pitfalls.
1833 [1] If you have third party modules, such as vmware, you
1834 should disable them at this point so they don't crash your
1837 [2] If you have legacy ISA devices, you may need to create
1838 your own device.hints to reflect your unique hardware
1841 [3] From the bootblocks, boot -s, and then do
1846 adjkerntz -i # if CMOS is wall time
1847 Also, when doing a major release upgrade, it is required that
1848 you boot into single user mode to do the installworld.
1849 For the 4.x -> 5.x upgrade, you will also see many messages about
1850 needing to recompile your userland. These are harmless and can
1851 be ignored while you proceed to the next step.
1853 [4] Note: This step is non-optional. Failure to do this step
1854 can result in a significant reduction in the functionality of the
1855 system. Attempting to do it by hand is not recommended and those
1856 that pursue this avenue should read this file carefully, as well
1857 as the archives of freebsd-current and freebsd-hackers mailing lists
1858 for potential gotchas.
1860 [5] Usually this step is a noop. However, from time to time
1861 you may need to do this if you get unknown user in the following
1862 step. It never hurts to do it all the time. You may need to
1863 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1864 install) after the buildworld before this step if you last updated
1865 from current before 20020224 or from -stable before 20020408.
1867 [6] 4.x boot loader can be used to boot a 5.x system, however
1868 it is difficult to do that at best. If you wish to try, then
1869 you should interrupt the boot and at the ok prompt type:
1871 ok boot /boot/kernel/kernel
1872 If this fails to work, you must install a new boot loader as
1875 [7] Before you upgrade, please make sure that you are not using
1876 compatibility slices. These are device names of the form /dev/ad0a
1877 without the actual slice name. These will break with 5.x and newer.
1878 You generally must update these entries to use the post FreeBSD
1879 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha
1882 [8] In order to have a kernel that can run the 4.x binaries
1883 needed to do an installworld, you must include the COMPAT_FREEBSD4
1884 option in your kernel. Failure to do so may leave you with a system
1885 that is hard to boot to recover.
1887 Make sure that you merge any new devices from GENERIC since the
1888 last time you updated your kernel config file.
1890 [9] When checking out sources, you must include the -P flag to have
1891 cvs prune empty directories.
1893 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1894 "?=" instead of the "=" assignment operator, so that buildworld can
1895 override the CPUTYPE if it needs to.
1897 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1898 not on the command line, or in /etc/make.conf. buildworld will
1899 warn if it is improperly defined.
1901 In case you would like to avoid installing new packages of everything,
1902 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1903 compatibility libraries are built which should allow you to continue
1904 using your existing software for a while. Alternatively, you can
1905 install the misc/compat4x port.
1907 [10] In order to create temporary files, /dev/random must be
1908 initialized by feeding data into it. src/etc/rc.d/preseedrandom
1912 This file contains a list, in reverse chronological order, of major
1913 breakages in tracking -current. Not all things will be listed here,
1914 and it only starts on March 15, 2000. Updating files can found in
1915 previous releases if your system is older than this.
