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 By a popular demand, a lot of NOFOO options were renamed
28 to NO_FOO (see bsd.compat.mk for a full list). The old
29 spellings are still supported, but will cause annoying
30 warnings on stderr. Make sure you upgrade properly (see
31 the COMMON ITEMS: section later in this file).
34 Auto-loading of ancillary wlan modules such as wlan_wep has
35 been temporarily disabled; you need to statically configure
36 the modules you need into your kernel or explicitly load them
37 prior to use. Specifically, if you intend to use WEP encryption
38 with an 802.11 device load/configure wlan_wep; if you want to
39 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
40 and wlan_xauth as required.
43 The behaviour of ppp(8) has changed slightly. If lqr is enabled
44 (``enable lqr''), older versions would revert to LCP ECHO mode on
45 negotiation failure. Now, ``enable echo'' is required for this
46 behaviour. The ppp version number has been bumped to 3.4.2 to
50 The wlan support has been updated to split the crypto support
51 into separate modules. For static WEP you must configure the
52 wlan_wep module in your system or build and install the module
53 in place where it can be loaded (the kernel will auto-load
54 the module when a wep key is configured).
57 The ath driver has been updated to split the tx rate control
58 algorithm into a separate module. You need to include either
59 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
62 Support for systems with an 80386 CPU has been removed. Please
63 use FreeBSD 5.x or earlier on systems with an 80386.
66 We have had a hack which would mount the root filesystem
67 R/W if the device were named 'md*'. As part of the vnode
68 work I'm doing I have had to remove this hack. People
69 building systems which use preloaded MD root filesystems
70 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
71 their /etc/rc scripts.
74 The size of struct tcpcb has changed again due to the removal
75 of RFC1644 T/TCP. You have to recompile userland programs that
76 read kmem for tcp sockets directly (netstat, sockstat, etc.)
79 The size of struct tcpcb has changed. You have to recompile
80 userland programs that read kmem for tcp sockets directly
81 (netstat, sockstat, etc.)
84 The FreeBSD keyword is no longer a requirement for a valid
85 rc.d script. The rc(8) and rc.shutdown(8) scripts no longer check
86 for the existence of this keyword when ordering rc.d scripts.
87 This change touches most of the file in /etc/rc.d; therefore,
88 if you have not modified any files in that directory it may
89 be easier to rm -rf /etc/rc.d and then use the -i switch with
93 One of the syscalls the 1:1 threading library libthr uses has
94 changed, thus breaking ABI compatibility. Make sure you rebuild
95 this library with the kernel.
98 A major sweep over the tty drivers to elimnate approx 3100
99 lines of copy&pasted code have been performed. As a part of
100 this change some tty devices have changed names:
101 sio devices are now named: {tty,cua}d%d[.init,.lock]
102 ucom devices are now named: {tty,cua}U%d[.init,.lock]
103 For other drivers see the commit logs.
106 The following libraries had their version number bumped up:
107 /lib/libm.so.2 -> libm.so.3
108 /lib/libreadline.so.4 -> libreadline.so.5
109 /usr/lib/libhistory.so.4 -> libhistory.so.5
110 /usr/lib/libopie.so.2 -> libopie.so.3
111 /usr/lib/libpcap.so.2 -> libpcap.so.3
112 FreeBSD 4.10 versions of these libraries will be added to the
113 compat4x collection. If you expect to be able to run old 4.X
114 executables you will need to remove the old versions of these
115 libraries. However note that any 5.X executables you have built
116 will stop working once you remove those old libraries. You should
117 have all your ports/packages rebuilt before removing the old
121 The pfil API has gained an additional argument to pass an inpcb.
122 You should rebuild all pfil consuming modules: ipfw, ipfilter
126 If named is enabled, the default is now to run it in a chroot
127 "sandbox." For users with existing configurations in
128 /etc/namedb the migration should be simple. Upgrade your
129 world as usual, then after installworld but before
130 mergemaster do the following:
132 If named is running: /etc/rc.d/named stop
135 mkdir -p /var/named/etc/namedb
136 cp -Rp namedb.bak/* /var/named/etc/namedb/
137 mergemaster (with your usual options)
138 If using the generated localhost* files:
139 cd /var/named/etc/namedb
140 /bin/sh make-localhost
141 rm -f localhost-v6.rev localhost.rev
142 /etc/rc.d/syslogd restart
143 /etc/rc.d/named start
145 If you are using a custom configuration, or if you have
146 customised the named_* variables in /etc/rc.conf[.local]
147 then you may have to adjust the instructions accordingly.
148 It is suggested that you carefully examine the new named
149 variables in /etc/defaults/rc.conf and the options in
150 /var/named/etc/namedb/named.conf to see if they might
151 now be more suitable.
154 BIND 9 has been imported into the base, and is now fully
155 functional. BIND 8 has now been removed. There are numerous
156 differences between BIND 8 and 9, and users with critical
157 named installations should read the migration documentation
158 in /usr/share/doc/bind9/misc/migration. There is also a
159 new instruction manual in /usr/share/doc/bind9/arm.
161 The key differences that most users will experience are in
162 how picky BIND 9 is about zone file format. If you are using
163 named as a resolving (caching) name server, you will likely
166 The following files are part of the old BIND 8 installation
167 and should be removed:
168 /usr/bin/dnskeygen /usr/bin/dnsquery /usr/libexec/named-xfer
169 /usr/sbin/named.restart /usr/sbin/ndc
171 The following files have moved to /usr/bin, and should be
172 removed from their old locations:
173 /usr/sbin/nslookup /usr/sbin/nsupdate
176 The format of the pflogd(8) logfile "/var/log/pflog" has changed for
177 architectures that have a 64 bit long type to make it compatible to
178 the standard pcap format. In order to prevent corruption move away
179 any old logfile before using a new pflogd(8).
182 debug.witness_* has been renamed to debug.witness.*. There are
183 compatibility tunables left in for a few days. Update loader.conf
187 The ifi_epoch change has been reverted because the ABI breakage
188 was too extensive. If you are running with a kernel/userland
189 containing the initial change (20040830), you should heed the
190 warning about ifconfig incompatibility when upgrading again.
191 With this change, 5.3 and 6.0 ifconfigs and kernels are once
195 A new variable, ifi_epoch, has been added to struct if_data
196 which is part if struct ifnet. This means all network drivers
197 and network monitoring applications need to be recompiled.
199 WARNING WARNING WARNING WARNING WARNING WARNING WARNING
201 This also breaks ifconfig compatibility. An old ifconfig will
202 not work with the new kernel and a new ifconfig will not work
203 with the old. It is strongly recommended that you make a copy
204 of your old ifconfig before installworld. If you are installing
205 remotely, you must copy over a new ifconfig before rebooting in
209 The default configuration for the network stack has been changed
210 such that it now runs without the Giant lock unless configured
211 otherwise. If you experience network-related instability, you
212 may wish to try setting "debug.mpsafenet=0" or compiling the
213 kernel with "options NET_WITH_GIANT". Details on the netperf
214 project may be found at:
216 http://www.watson.org/~robert/freebsd/netperf/
218 Including the 20040828 announcement of configuration change
222 PFIL_HOOKS are a fixed part of the network stack now and do not
223 need to be specified in the kernel configuration file anymore.
226 Netgraph changed its message format slightly to align the data
227 portion well on 64 bit machines.
228 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
229 pppoed, bluetooth, ATM) should be recompiled when a new kernel
233 IPFW has been converted to use pfil(9). This change is
234 transparent to userland and preserves the ipfw ABI. The ipfw
235 core packet inspection and filtering functions have not been
236 changed, only how ipfw is invoked is different.
239 The RANDOM_IP_ID option has been replaced by the sysctl
240 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
241 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
244 The size of 'struct ifnet' has changed due to the addition of the
245 if_carp placeholder. All kernel modules implementing network
246 interfaces must be recompiled as a result.
249 Module loading has been fixed. Some older installations will
250 drop proper module_path initialization and modules will fail to
251 load properly. If you have a line in /boot/loader.rc that says:
252 "initialize drop", do (i386 only):
253 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
254 chown root:wheel /boot/loader.rc
255 chmod 444 /boot/loader.rc
258 making /dev/(null|zero) into a module proved to be too unpopular,
259 so this bit has been revoked from the previous (20040801) entry.
262 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
263 so you may wish to add them to your kernel config file. See
264 GENERIC for examples.
267 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
268 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
269 has broken C++ ABI compatibility with previous releases yet again
270 and users will have to rebuild all their C++ programs with the new
271 compiler. If you are getting run-time error such as
272 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE"
273 This entry does apply to you.
275 A new unit-at-a-time optimization mode, which is default in this
276 compiler release, is more aggressive in removing unused static
277 symbols. This is the likely cause of 'make buildworld' breakages
278 with non-default CFLAGS where optimization level is set to -O2
281 With the upgrade of the system compiler, the kernel has been upgraded
282 to match the new system compiler. This makes it impossible to build
283 a new kernel with the old compiler. Upgrade your system via
284 make buildworld and make kernel (see below) to fix this problem.
287 The size of 'struct ifnet' has changed due to the addition of
288 the IFF_NEEDSGIANT flag (and what it implies). All kernel
289 modules implementing network interfaces must be recompiled as
293 The sound device drivers are renamed. `sound' is always required,
294 while `snd_*' should be configured accordingly to your hardware.
295 Refer to NOTES for the detail of the drivers.
298 __FreeBSD_version bumped to 502122.
301 The console initialization on Alpha has been reworked and is now
302 identical to other platforms. This means that the hardcoding of
303 the serial console and the debug port has been removed. As such,
304 hints (hint.sio.0.flags="0x10") are now required for the sio(4)
305 driver to become a console or debug port. The NO_SIO option has
306 been decommissioned because of this.
307 Running mergemaster is the easiest way to ensure your
308 'boot/device.hints' has the needed line.
311 A revamp of the debugging code in the kernel with some visible
312 changes beyond just the debugging experience:
313 o The DDB option is now specific to the DDB debugger backend
314 and should not be used any more for conditional compilation
315 of debugging code for when debugging is enabled. Use the KDB
317 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
318 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
319 respectively. This is in line with the first bullet.
320 o The remote GDB support has been untangled from DDB and needs
321 to be enabled separately now. Use the GDB option for this.
322 o The GDB_REMOTE_CHAT option has been removed. Support for this
323 homegrown feature is discontinued. The GDB remote protocol
324 supports console output and it makes sense to use that.
325 o The DDB_NOKLDSYM option has been removed. The DDB debugger
326 now supports both direct symbol table lookups as well as KLD
327 symbol lookups through the linker.
330 Bluetooth code has been marked as non-i386 specific.
331 __FreeBSD_version has been bumped to 502121 to mark this change.
334 The native preemption has been added to the kernel scheduler.
335 There is some report that the ULE scheduler was broken in some
336 machines and we encourage users using the ULE scheduler either
337 stick with a known good kernel, or temporarily switch to the 4BSD
338 scheduler as a workaround.
341 The netgraph ABI version number has been incremented to indicate
342 an incompatible change in the ABI. Old netgraph nodes will refuse
343 to attach until recompiled. Netgraph now uses mbuf tags to move
344 metadata and this commit removes its home-grown metadata facility.
345 Nodes should just recompile, unless they use metadata, in which
346 case the changes are simple; the file ng_ksocket.c serves as an
347 example of such changes.
349 This also broke i4b, although the compile problem has been papered
353 ACPI has been updated to disable known-bad BIOS revisions. A message
354 will be printed on the console indicating that ACPI has been disabled
355 automatically and that the user should use a newer BIOS, if possible.
356 If you think ACPI does work on your system and want to override
357 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
361 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
362 separated now. It uses the newly created "_pflogd" user/group
363 combination. If you plan to use pflogd(8) make sure to run
364 mergemaster -p or install the "_pflogd" user and group manually.
367 Network interface cloning has been overhauled. This change will
368 require a recompile of modules using cloning and modification of
369 external ones to the new API. __FreeBSD_version has been bumped
370 to 502119 to mark this change. Additionally, users creating
371 stf(4) interfaces via "ifconfig stf" will need to update their
372 scripts as this will create an interface named "stf" instead of
373 "stf0" and ifconfig will not print "stf0" to stdout.
376 On 20040524, the /etc/rc.d/nsswitch script was modified to
377 automatically create /etc/nsswitch.conf on startup if it did
378 not already exist. Unfortunately, an error in the man page
379 was carried over to the script, resulting in incorrect
380 nsswitch settings. The simplest remedy is to remove both
381 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
382 during the next reboot.
385 The return value of sema_timedwait(9) has been changed to
386 make it consistent with cv_timedwait(9). Be sure to recompile
387 the ips module and any third-party modules which call
391 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
392 Make sure to recompile modules and any userland that makes use of
393 sizeof(struct ifnet). In order to get the altq headers in place
394 please recompile and reinstall world.
397 Splitting kern_thread.c into 2 files (adding kern_kse.c)
398 requires that you re-run config after updating your tree.
401 The MIDI drivers have been removed. Until the new module-friendly
402 ones are merged, remove or comment out midi and seq from your
403 kernel configuration.
406 Due to a new option in ipfw (versrcreach) the ipfw(8) command
407 needs to be recompiled. Normal accept/reject rules without
408 options are not affected but those with options may break until
409 ipfw(8) is recompiled.
412 Due to changes in the callout ABI, kernels compiled after this
413 date may be incompatible with kernel modules compiled prior to
417 The PCI bus power state stuff has been turned on. If this causes
418 problems for your system, please disable it using the tunable
419 hw.pci.do_powerstate=0.
422 The bulk of the pci problems have been fixed, although the floppy
423 drive is still broken.
426 A substantial update to the pci bus resource and power management
427 have been committed. Expect a bumpy ride for a few days until
428 the unanticipated problems have been resolved.
431 Due to changes in the the Yarrow initialization process,
432 /dev/random needs to be fed before operations requiring
433 temp files can succeed in single user mode. This includes
434 running "make installworld". /dev/random may be fed by running
435 "/etc/rc.d/initrandom start" or with 20040415 source by running
436 "/etc/rc.d/preseedrandom".
439 The debug.mpsafenet tunable controls whether the kernel Giant
440 lock is held across the lower levels of the network stack, and
441 by default is turned off. In the few days following 20040322,
442 the behavior of debug.mpsafenet will change such that this
443 tunable controls Giant over all levels of the network stack.
444 If you are currently setting debug.mpsafenet to 1, you should
445 set it back to 0 (the default) again during the change-over.
446 An additional note will be added to UPDATING when sufficient
447 locking is merged to permit this to take place.
450 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
451 64-bits. This is a very major incompatible change, so people
452 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
453 detailed instructions on how to make this upgrade. People
454 upgrading FreeBSD on other platforms can ignore this event.
457 The packet filter (pf) is now installed with the base system. Make
458 sure to run mergemaster -p before installworld to create required
459 user account ("proxy"). If you do not want to build pf with your
460 system you can use the NO_PF knob in make.conf.
461 The pf system consists of the following three devices:
463 device pflog # optional
464 device pfsync # optional
467 If you are having trouble with the libc_r -> libpthread transition
468 (see the 20040130 entry), place the following lines at the top of
471 libc_r.so.5 libpthread.so.1
472 libc_r.so libpthread.so
474 This will cause all programs and libraries linked against libc_r
475 to use libpthread instead.
478 Some sshd configuration defaults have changed: protocol version 1
479 is no longer enabled by default, and password authentication is
480 disabled by default if PAM is enabled (which it is by default).
481 OpenSSH clients should not be affected by this; other clients may
482 have to be reconfigured, upgraded or replaced.
485 The ABIs defined in <resolv.h> and <netdb.h> have been updated
486 to support improved reentrancy. Multi-threaded programs that
487 reference the "_res" or "h_errno" symbols may experience some
488 problems if they are not recompiled. Single-threaded programs
489 should remain unaffected.
492 routed has been updated in the base system from the vendor
493 sources, routed v2.27, from rhyolite.com. This change means that
494 for users who use RIP's MD5 authentication feature, FreeBSD
495 -CURRENT's routed is now incompatible with previous versions
496 of FreeBSD; however it is now compatible with implementations
497 from Sun, Cisco and other vendors.
500 The tcpcb structure has changed and makes a recompile of libkvm
501 and related userland network utilities necessary.
504 The cdevsw structure has changed in two externally visible ways.
505 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
506 Second, the d_version field must be filled in with D_VERSION.
507 Drivers outside the tree will need to be updated.
510 The /etc/rc.d/ttys script has been removed. It is no longer
511 necessary since devfs has been mandatory for some time.
514 libkse has been renamed back to libpthread and is now the
515 default threads library. The gcc -pthread option has also
516 been changed to link to libpthread instead of libc_r. For
517 alpha and sparc64 machines, libkse is not renamed and links
518 are installed so that libpthread points to libc_r. Until
519 the ports system is updated to handle this change, it is
520 recommended that folks install an /etc/libmap.conf(5) that
521 maps libc_r to libpthread. If you have any binaries or
522 libraries linked to libkse, then it is also recommended
523 that you map libkse to libpthread. Anyone that is using
524 nvidia supplied drivers and libraries should use a libmap.conf
525 that maps libpthread to libc_r since their drivers/libraries
526 do not work with libpthread.
529 ULE has entered into its probationary period as the default scheduler
530 in GENERIC. For the average user, interactivity is reported to be
531 better in many cases. On SMP machines ULE will be able to make more
532 efficient use of the available parallel resources. If you are not
533 running it now, please switch over, replacing the kernel option
534 SCHED_4BSD with SCHED_ULE.
537 Move LongRun support out of identcpu.c, where it hardly
538 belongs, into its own file and make it opt-in, not mandatory,
539 depending on CPU_ENABLE_LONGRUN config(8) option.
542 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
543 if the login process is unable to successfully set the
544 process credentials to include all groups defined for the
545 user. The current kernel limit is 16 groups; administrators
546 may wish to check that users do not have over 16 groups
547 defined, or they will be unable to log in.
550 The ACPI module has been reactivated. It is no longer required
551 to compile ACPI support into kernels statically.
554 The statfs structure has been updated with 64-bit fields to
555 allow accurate reporting of multi-terabyte filesystem
556 sizes. You should build world, then build and boot the new kernel
557 BEFORE doing a `installworld' as the new kernel will know about
558 binaries using the old statfs structure, but an old kernel will
559 not know about the new system calls that support the new statfs
561 Note that the backwards compatibility is only present when the
562 kernel is configured with the COMPAT_FREEBSD4 option. Since
563 even /bin/sh will not run with a new kernel without said option
564 you're pretty much dead in the water without it. Make sure you
565 have COMPAT_FREEBSD4!
566 Running an old kernel after a `make world' will cause programs
567 such as `df' that do a statfs system call to fail with a bad
568 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
569 that cfsd (ports/security/cfs) needs to be recompiled after
570 these changes are installed.
572 ****************************DANGER*******************************
574 DO NOT make installworld after the buildworld w/o building and
575 installing a new kernel FIRST. You will be unable to build a
576 new kernel otherwise on a system with new binaries and an old
580 Some netgraph string length constants have been changed. This
581 change requires the netgraph kernel modules and all netgraph
582 userland components to be in sync. Especially users who require
583 netgraph to boot need to make sure to have world and kernel in
584 sync before rebooting.
587 Hyperthreading logical CPU's are no longer probed by default
588 when using the MP Table. If ACPI is being used, then logical
589 CPUs will be probed if hyperthreading is enabled in the BIOS.
590 If ACPI is not being used and hyperthreading is enabled in the
591 BIOS, logical CPUs can be enabled by building a custom kernel
592 with the option MPTABLE_FORCE_HTT enabled.
595 The i386 APIC_IO kernel option has been replaced by
596 'device apic'. The ACPI module has also been temporarily
597 disabled, so ACPI must be statically compiled into your
598 kernel using 'device acpi' if you wish to use the ACPI driver.
601 The API and ABI of struct ifnet have been changed by removing
602 the if_name and if_unit members and replacing them with
603 if_xname, if_dname, and if_dunit. All network drivers and most
604 userland programs which include net/if_var.h must be updated
605 and recompiled. __FreeBSD_version has been bumped to 501113 to
609 Changes to the cdevsw default functions have been made to remove
610 the need to specify nullopen() and nullclose() explicitly.
611 __FreeBSD_version bumped to 501110.
614 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
615 mount_cd9660(8) need to be in sync with kernel.
618 Fix a bug in arplookup(), whereby a hostile party on a locally
619 attached network could exhaust kernel memory, and cause a system
620 panic, by sending a flood of spoofed ARP requests. See
621 FreeBSD-SA-03:14.arp.
624 A change to /etc/defaults/rc.conf now causes inetd to be started
625 with `-C 60' if it is not overridden in /etc/rc.conf. This
626 causes inetd to stop accepting connections from an IP address
627 that exceeds the rate of 60 connections per minute.
630 The following rc.d scripts have been removed and should be
631 deleted from your installation: atm2.sh atm3.sh devdb
632 localdaemons network1 network2 network3. Depending on when
633 you last updated world and used mergemaster(8) you may or
634 may not have problems during the rc boot sequence. The simplest
635 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
636 The atm2.sh atm3.sh and devdb scripts were removed some time
637 ago, so depending on when you installed -CURRENT these scripts
638 may or may not exist on your system.
641 ATAng has been committed. You need to build world as sys/ata.h
642 has changed, and userland atacontrol depends on it.
643 If you use ATA SW raids you need "device ataraid" in your
644 kernel config file, as it is no longer pulled in automatically.
647 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
648 Among other things, this changes the device enumeration to be
649 closer to Solaris. Be aware that, this can even cause the machine
650 to not boot without manual intervention before the fstab is adjusted.
653 All current USB and Firewire quirks in da(4) have been deprecated
654 and will be removed for 5.2. If this causes failure for your
655 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
656 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
657 so the quirk can be re-enabled.
660 Problems with entry 20030714 have been corrected and no known issues
661 with /rescue and -j exist for host systems after this point in time.
664 FPU-less support has been removed from FreeBSD. Chances are you won't
665 notice. 386+387 support should still work after this change, but
666 it is now a minimum requirement for the i386 port that you have real
670 Some people are having problems with changes related to /rescue.
671 If you are building -j N, you will need to define NO_RESCUE. Others
672 will need to define it if /rescue has issues with their environment.
673 People should report those issues to current@.
676 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
677 across this point. Further, it might be a good idea to remove
681 Remove deprecated locale names and transition period code
682 for them, finishing switching to the new scheme. Check your
683 LANG environment variable.
686 CCD has been changed to be a fully GEOMified class. Kernel
687 and ccdconfig(8) needs to be in sync, this is particularly
688 important to remember beforehand if your source tree is on
689 a ccd device. Consider making a copy of the old ccdconfig
690 into /boot/kernel.good or wherever you keep your backup
694 There was a small window in which sed(1) was broken. If you
695 happen to have sed(1) installed during that window, which is
696 evidenced by an inability to build world with the failure
697 given below, you need to manually build and install sed(1)
698 (and only sed(1)) before doing anything else. This is a one-
699 time snafu. Typical failure mode:
701 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
702 targmatch.h:7:1: null character(s) ignored
703 targmatch.h:12:1: null character(s) ignored
704 targmatch.h:16:1: null character(s) ignored
707 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
708 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
709 usr.bin/sed/process.c).
712 Kerberos 5 (Heimdal) is now built by default. Setting
713 MAKE_KERBEROS5 no longer has any effect. If you do NOT
714 want the "base" Kerberos 5, you need to set NO_KERBEROS.
717 groff has been updated. If you try to do a buildworld and
718 get an infinite loop in troff, update to May 4th or newer. If you
719 have a newer kernel than userland, you may need to set the OSRELDATE
720 to 500110 in your environment before starting a buildworld.
723 The old rc system has been removed. Please report any problems
724 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
725 Your personal versions of these files will not be removed, so you can
726 continue to use them. However, you should take great care when updating,
727 especially when using mergemaster, since the compatibility code that
728 utilizes these old scripts has also been removed.
731 A bug has been fixed in /dev/devctl which would cause devd
732 to hang on boot, were it not for a workaround in devd. The
733 work around in devd will be removed around 20030507. You
734 have until then to upgrade your kernel before updating
735 userland. In general, you should have a userland and
736 kernel that's in sync with each other. However, given the
737 effects of this bug (hang on boot when starting devd), some
741 Alphas with libc from between 20030312 and 20030329 exhibit
742 floating point exceptions (FPEs), most notably in awk(1)
743 while upgrading the system through a buildworld.
745 So, to successfully upgrade your Alpha, you must either
746 downgrade your libc.so to a pre-20030312 version, or update
747 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
748 to CFLAGS, then forcibly rebuild and install libc:
750 cd /usr/src/lib/libc && \
751 make cleandir && make obj && \
752 make -DNOMAN -DNOPROFILE all && \
753 make -DNOMAN -DNOPROFILE install
756 sendmail 8.12.7 has been imported. It has one important
757 change for IPv6 users. The default submit.mc now uses
758 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
759 used to connect to the MTA. Users on IPv6-only machines
760 will need to edit /etc/mail/submit.mc appropriately.
763 NODEVFS option has been removed and DEVFS thereby made standard.
764 This makes all references to MAKEDEV obsolete, and they should
765 be removed when convenient.
768 The name of the device for the ofw console has changed, sparc64 users
769 must run mergemaster to update their installed /etc/ttys.
772 The scheduler framework has grown a second scheduler and consequently
773 you must specify one and only one scheduler in your kernel config.
774 The cvs config files have been updated to use the old scheduler
775 which may be selected via 'options SCHED_4BSD'. If you would like
776 to try the new, much more experimental, scheduler please try
777 'options SCHED_ULE' and contribute to the arch@ discussion.
780 A new version of the wi driver has been imported into the tree.
781 One now must have device wlan in the config file for it to operate
784 In addition, there have been some changes to how wi devices are
785 configured for point to point links to bring it more in line
786 with the former way of doing things, as well as compatibility
790 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
791 used an incompatible form of ABI for returning structures and unions
792 which FreeBSD's GCC maintainers were not aware of relative to previous
793 versions of FreeBSD. We have gone back to the ABI for now, and any
794 code compiled which is required to interoperate with other code (not
795 built at the same time) returning structs or unions should be
799 A name change in /etc/netconfig has been reverted to stay
800 compatible with suns TIRPC and also with NetBSD. You need
801 to run mergemaster after make world. A new libc does still work
802 with an outdated /etc/netconfig for some time, but you'll get
803 a warning. This warning will be removed in 20030301.
806 The recent binutils upgrade marks a kernel flag day on
807 sparc64: modules built with the old binutils will not work
808 with new kernels and vice versa. Mismatches will result in
809 panics. Make sure your kernel and modules are in sync.
812 The value of IPPROTO_DIVERT has changed. Make sure to keep
813 your kernel, netstat, natd and any third-party DIVERT
817 Old, compatibility slices have been removed in GEOM kernels.
818 This means that you will have to update your /etc/fstab to
819 not use disk devices of the form /dev/ad0a. Instead, you
820 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
821 partition really is on. The old device names have gone
822 away, so if you use them anywhere else, you must also adjust
823 those uses. (This doesn't affect the disks formatted in
824 the ``dangerously-dedicated'' mode.)
827 Alphas with kernels from between 20020830 and 20021023 and/or
828 rtld (ld-elf.so.1) older than 20021023 may experience problems
829 with groff while doing a buildworld (kernel: "out of memory",
830 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
831 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
833 So, to successfully upgrade your Alpha, you must either
834 upgrade your kernel and rtld first (which might be a bit
835 tricky), or avoid running the bootstrapped groff during the
836 "transitional" buildworld. To avoid running groff during the
837 transitional upgrade run make buildworld with -DNOMAN,
838 -DNO_SHAREDOCS, and -DNO_LPR.
841 gcc has been upgraded to 3.2. It is not all binary compatible
842 with earlier versions of gcc for c++ programs. All c++
843 programs and libraries need to be recompiled.
845 Also, if you encounter g++ issues, rm /usr/include/g++/* before
846 doing an installworld to make sure that stale files are removed.
849 Our /etc/termcap now has all the entries from the XFree86 xterm
850 almost unchanged. This means xterm now supports color by default.
851 If you used TERM=xterm-color in the past you now should use
852 TERM=xterm. (xterm-color will lead to benign warnings).
855 A "bug" in gcc(1) that was hiding warning in system headers was
856 fixed. It's probably time to add -DNO_WERROR to your make line
860 COPY is being deprecated. The 20010530 change was reverted, as
861 it causes far more pain than was expected, and to always compare
862 before installing, please use INSTALL="install -C" again. The
863 -C option is now silently ignored when used with the -d option.
866 Problems with libc_r clients like KDE and GNOME have been resolved.
867 There are still some minor problems with some signals but the
868 system is stable enough for general use again. SMP is less so than UP
869 but each can successfully complete multiple buildworlds.
870 Libkvm needs to be recompiled due to KSE.
873 Now would be a bad time to upgrade. Something in or near the
874 KSE commit totally broke programs using libc_r like KDE and
878 The k5su utility installed as part of Kerberos 5 is no longer
879 installed with the set-user-ID bit set by default. Add
880 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
881 with the set-user-ID bit set.
884 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
885 Unfortunately our native GDB (at version 4.18) does not understand
886 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
887 generated debugging information for our native GDB.
890 Due to the way CVS works, it may not properly update src/contrib/gcc
891 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
892 and then do a cvs update.
895 When exec'ing set[ug]id executables, the kernel now ensures that the
896 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
899 New sendmail startup scripts have been installed to make it
900 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
901 variable sendmail_enable to "NO" no longer prevents any sendmail
902 daemons from starting. Instead, either set sendmail_enable to
903 "NONE" or change mta_start_script to a script for starting
904 an alternative MTA. Setting mta_start_script to "" will
905 also prevent any MTA from being started at boot.
908 UCONSOLE is no longer a valid kernel option.
911 FreeBSD 5.0 DP-1 was basically branched today.
914 Warnings are now errors in the kernel. Unless you are a developer,
915 you should add -DNO_WERROR to your make line.
918 sendmail 8.12.2 has been imported. The sendmail binary is no
919 longer a set-user-ID root binary and the infrastructure to support
920 command line mail submission has changed. Be sure to run
921 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
922 and /etc/mail) and read /etc/mail/README for more details.
924 Due to the import of sendmail 8.12.2, a new user and group are
925 required in order for sendmail to run as a set-group-ID
926 binary. A 'make installworld' will use the new user and group
927 to set the owner and group of /var/spool/clientmqueue and will
928 fail if the new user and group do not exist. The 'smmsp' user
929 and group must be merged from src/etc/group and
930 src/etc/master.passwd before using 'make installworld'.
931 'mergemaster -p' will do this. You may need to install
932 mergemaster before this will work if you are updating from a
933 very old version of current. The updating recipe has changed
937 The preferred configuration method for PAM is now /etc/pam.d/
938 rather than /etc/pam.conf. If you have an unmodified
939 pam.conf, just delete it after your next mergemaster run. If
940 you have local modifications, you can use
941 /usr/src/etc/pam.d/convert.pl to incorporate them into your
944 Please see the following url for more details:

952 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
953 started out its life in the ISDN4BSD project as an offspring
954 from sys/net/if_spppsubr.c, which eventually got a life of its
955 own. All the accumulated features and bug fixes of the i4b
956 version have now been merged back into the base system's
957 version now. The only user-visible change resulting from this
958 is that i4b's sppp(4) interfaces are to be managed with
959 spppcontrol(8) again, since ispppcontrol(8) has been retired
960 as well. (There has never been rc file support for
961 ispppcontrol in -current, but only in -stable. That will be
962 reverted by the time the changes are MFCed.)
965 The fdc(4) driver has been updated and now automatically
966 recognizes media in `standard' formats (like 1440 KB and
967 720 KB for a 3.5" high-density drive) when accessing the
968 default device node (e. g. /dev/fd0). The old variety of
969 floppy device nodes /dev/fd*.* is no longer present by
970 default, devices can be created (in DEVFS) on demand. They
971 will need to be customized then for `odd' densities using
975 The bugs in procfs' debugging support code have been fixed,
976 and truss(1) now works again.
979 Daily security checks have been split out to use the periodic(8)
980 scripts. Some change in configuration may be necessary. Please
982 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
986 sos added VCD/SVCD support to ata driver and that needs the
987 kernel and burncd to be in sync.
990 The procfs pseudo-filesystem has now been converted to use the
991 pseudofs framework. If you have 'options PROCFS' in your
992 kernel config, you'll need to add 'options PSEUDOFS' if it's
995 This change temporarily breaks truss(1); use ktrace(1) instead
996 until the issue has been resolved.
999 A security hole in OpenSSH involving `UseLogin yes' has been
1003 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
1004 after this date. You need to do this only once.
1007 Most of the awk issues have been resolved. Some rough
1008 edges may be left, but for the most part things should be
1009 back to "normal." For CURRENT's usual definition of "normal."
1012 Awk has been upgraded to the one true awk from bell labs. Expect
1013 choppy waves in the upgrade process.
1016 The asr driver problem has been resolved.
1019 Due to changes in other parts of the system, the asr driver
1020 now causes the system to panic on boot. Do not use it pending
1021 correction. Comment it out of any kernel config file that you
1022 try to use from this date forward.
1025 When crossbuilding, use TARGET=xxx where you used to use
1026 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
1027 unless you are changing both of them. To cross build pc98 on
1028 an alpha, for example, you need to set TARGET=pc98 and
1032 The kernel interface that burncd depends on has changed.
1033 You must recompile both the kernel and userland applications
1037 When crossbuilding, please set TARGET_ARCH rather than
1038 MACHINE_ARCH to indicate the target. In the future, one will
1039 set TARGET_MACHINE where you set MACHINE now. At the moment,
1040 setting MACHINE alone for same MACHINE_ARCH machines works
1041 (eg, you can build pc98 on an i386 machine and vice versa).
1044 Some weird problems result from using ACPI on some machines.
1045 To disable ACPI you can add
1046 hint.acpi.0.disabled="1"
1047 to /boot/loader.conf (or by putting set X=Y at the boot
1048 loader "ok" prompt).
1050 Alternatively, you can remove it from /boot/kernel/acpi.ko
1051 or use the MODULES_OVERRIDE function in your kernel config
1052 file and not list acpi in that list.
1055 The buildworld has been fixed. You may need to install
1056 the 4.x compatibility libraries for some old binaries
1057 to work. Add COMPAT4X=true to your /etc/make.conf to
1058 get them installed on every installworld, or execute the
1059 following to get them installed only once:
1060 cd src/lib/compat/compat4x.<arch>
1062 You will see ``__stdoutp undefined'' until you do this.
1065 There's a bug in the world build process. The cross-tools
1066 are build with the NEW headers, but the OLD libc.a. This
1067 leads to all kinds of problems with the new libc. A temporary
1068 workaround is to add
1069 CFLAGS="-O -pipe -D_OLD_STDIO"
1070 before building world when upgrading from 4.x to current. This
1071 can be removed afterwards.
1073 A proper fix to the buildworld target is needed.
1076 Peter has committed his new kthread nfs client/server code.
1077 NFS may be unstable after this date.
1080 KSE has hit the tree. Lots of things are now different in
1081 the kernel. While a few problems were introduced in the
1082 initial commit, most of the major ones have been found and
1086 In OLDCARD, CardBus bridges appear to be stable. The work
1087 arounds described in the 20010604 entry are now no longer
1088 necessary and will be ignored. Most insert/remove problems
1089 have been rectified around this date.
1092 named now runs as user bind and group bind rather than as
1093 root. If named_enable is set to YES in /etc/rc.conf, ensure
1094 that user bind is available in /etc/passwd (using vipw(8))
1095 and that group bind is available in /etc/group. Also make
1096 sure that user or group bind has read (and not write)
1097 permission for your name server configuration and that it
1098 has read and write permission for your slave zone files and
1101 If you wish to continue to run named as root (a less secure
1102 alternative), add a line to /etc/rc.conf saying
1107 The PAM libraries have had an API upgrade that is beyond
1108 the ability of the shared library major number to handle.
1109 It is manifested by PAM-using ports dumping core. The
1110 solution is to rebuild those ports.
1113 The kernel compile module has moved from src/sys/compile/FOO
1114 to src/sys/${MACHINE}/compile/FOO.
1117 The pccard modem issue from 20010613 has been corrected.
1118 OLDCARD support is still a little weak in -current. slot 1 is
1119 known not to work on some TI based cardbus bridges. Some
1120 cardbus bridges do not properly detect insert/removal events.
1121 IRQ configuration needs more safety belts.
1124 Softupdates problems have been corrected.
1127 Peter ripped out the linkerset support. You must, as always,
1128 rerun config after you cvsup if you are using the traditional
1129 kernel building methods.
1132 pccard modems may not work with current after 20010604 date. Some
1133 do, others result in panics. *MAKE*SURE* that you update your
1134 config and /etc/rc.conf ala the 20010604 entry, or you will have
1135 problems (this issue will be fixed, it just hasn't been yet).
1138 SOFTUPDATES seem to be broken since the middle of May or so. Do not
1139 use them in current. You can disable softupdates on all mounted
1140 partitions, or remove SOFTUPDATES the kernel config file.
1143 After Peter's commits to the hints code, people have been noticing
1144 that certain devices are attached (or try to) twice. This is due
1145 to having both static hints as well as a /boot/device.hints. To
1146 work around this issue, please use only one or the other mechanism
1147 until this bug is fixed.
1149 Please note that a feature of config is that if you have config
1150 file FOO and FOO.hints, it automatically adds FOO.hints to the
1151 hints.c file, whether you want it to or not.
1154 Locale names have changed to match other systems better.
1157 pccard support for pci cards has been committed. You must change
1158 your /etc/pccard.conf irq lines. It must match the irq used by
1159 pcic device. Interrupt storms may result if you fail to do this.
1160 Interrupt storms look a lot like a hang.
1162 You must also install a new pccardd, otherwise you will get an
1163 interrupt storm at card reset time (just after it tells you what
1166 pccardd_flags="-I" is necessary for the time being. It tells pccardd
1167 not to ask the kernel if the interrupt is really free or not before
1168 using it. You can either change the /etc/pccard.conf irq lines to
1169 match pcic, or add "-i X" to the pccardd_flags.
1172 INSTALL=install -C is being deprecated. If you want to do this,
1173 use COPY=-C instead. The former method will be supported for only
1174 a limited time. If you see
1176 install: warning: the -d and -C options may not be specified together
1178 in your makeworld, then you need to migrate towards using
1182 It appears that vm is now stable enough to use again. However,
1183 there may be other problems, so caution is still urged. alpha
1184 definitely is in bad shape.
1187 Minor repo damage has happened. This may cause problems
1188 with cvsup of ports. If you get errors, please see
1189 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
1190 at the bottom for details on a workaround. The error message
1192 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
1195 Vm and/or swapping are busted on -current. Please be patient.
1198 pccard has had much reorganizational work done to it over
1199 the past few days. Everything should still work, but if
1200 not, please contact imp@freebsd.org.
1203 ata ioctl changed. Make sure to recompile both kernel and
1204 userland at the same time.
1207 New ncurses imported.
1210 DEVFS is now opt out, not opt in. Barring major problems, this
1211 will be the only way to go starting July 1.
1214 OpenSSH has been updated to 2.9. Some defaults are different,
1215 including RhostsRSAAuthentication, which changes from yes to no.
1218 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
1221 Building perl was broken at 02:25:25 PDT.
1224 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
1225 go back in the water.
1228 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
1229 this date, but before the correction date.
1232 old fsck and new kernel interactions appear to have been fixed.
1235 fsck and the kernel were changed to handle some optimizations
1236 to directory layout. This breaks backward compatibility.
1237 Update only if you understand that you must not use the old
1238 fsck with the new kernel ever.
1241 fsck has changed the meaning of the pass column in /etc/fstab.
1242 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1243 details. It is unclear if changes to /etc/fstab are necessary.
1246 portmap had changed name to rpcbind for maximum POLA in your
1247 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1248 other rpc based programs that rely on portmapper will not work
1249 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1252 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1253 and ATA_ENABLE_TAGS are no longer kernel options. They have
1254 been replaced by tunables. See ata.4 for details.
1257 The fxp driver was converted to use miibus. If you compile
1258 fxp into your kernel statically, you will need to add miibus.
1261 The wi device now defaults to BSS (infrastructure) mode
1265 /dev/urandom should be a symbolic link to /dev/random now.
1266 Users of current not using DEVFS need to run MAKEDEV std.
1267 ssh might not work if you don't.
1270 The ed driver has been updated. It now allows mii attachments,
1271 which means that you must include the miibus in your kernel if
1272 you use the ed driver.
1275 The problems with libc have been corrected. It is now mostly
1276 safe to go back into the water.
1279 The size of FILE was changed. This breaks upgrading. If
1280 you must upgrade, be prepared for pain. It also breaks almost
1281 all binaries that you've compiled on -current. You are warned
1282 that before upgrading would be a good time to do a level 0
1283 dump of your system. No, really, I mean it this time.
1285 To get to the new system, you'll need to use the following
1286 workaround. Hopefully this can be sorted out so that we
1287 don't have to move this to the updating section.
1289 To get around the installworld problem, do:
1290 # cd /usr/src/usr.bin/sed
1294 If that doesn't work, then try:
1295 # make -k installworld
1299 DEVFS is now the default. If you use vinum, make sure that you
1300 do not include devfs in your kernel as problems result.
1303 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1304 Remove them from your config.
1307 ****************************** WARNING ******************************
1308 buildkernel has been changed slightly
1309 ****************************** WARNING ******************************
1310 KERNCONF replaces the variable KERNEL for buildkernel. You
1311 should update your scripts and make.conf accordingly.
1314 config has changed to allow DEV_FOO as a replacement for NFOO.
1315 This requires a new config to build correctly.
1318 The kernel option I386_CPU is now mutually exclusive with the
1319 other cpu types. If you have an i386 system, be sure that it
1320 only had this line. Remove it for all other configurations.
1323 Changes to the kernel require it and burncd be in sync.
1326 Everyone who has hw.sndunit set to something in
1327 /etc/sysctl.conf, it is now hw.snd.unit.
1330 ex and vi were broken by some changes to sys/queue.h. If you
1331 have a bad vi, you will see make buildworld fail with a core
1332 dump while building termcap. You can work around this problem
1333 by adding -k to your make buildworld. This will cause the
1334 build to complete and install a new vi. Once that's done, you
1335 can rebuild again without the -k to pick up anything that
1336 might have been ignored by the -k option.
1338 Others have suggested that you can just rebuild libc if your
1339 vi/ex is dynamically linked, but I've not received any reports
1343 There have been some changes to libcrypt in -current. The
1344 libscrypt/libdescrypt symlink silliness is gone and the installed
1345 libcrypt is fully functional. Be aware of this.
1348 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1349 now require the addition of flag 0x80000 to their config line
1350 in pccard.conf(5). This flag is not optional. These Linksys
1351 cards will not be recognized without it.
1354 Important new FreeBSD-version stuff: PAM support has been worked
1355 in, partially from the "Unix" OpenSSH version. This requires
1356 adding the following in pam.conf:
1358 sshd auth sufficient pam_skey.so
1359 sshd auth required pam_unix.so try_first_pass
1360 sshd session required pam_permit.so
1363 cvs updated to 1.11.
1366 The random device needs more entropy, so you need to make sure
1367 that you've run mergemaster to get a /etc/rc which will seed
1368 /dev/random. If you don't and the system hangs after ldconfig,
1369 then banging on the keyboard randomly until it unhangs is one
1373 ****************************** WARNING ******************************

1390 The ports tree's new layout is in place. Be sure to update
1391 your entire ports tree, or you will have problems.
1394 The perl build procedure no longer installs miniperl, nor uses
1395 the installed miniperl. It is recommended that you delete
1399 This weekend the ports tree will be updated to a new layout.
1400 It will be in an inconsistent state until noted in the UPDATING
1401 file, or with asami-san's message to the relevant mailing
1402 lists. With this new layout, you'll need to update the whole
1403 tree for anything to work.
1406 There was a change in the passwd format. Need more information.
1409 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1410 place. Please update boot loader (not the boot blocks) at the
1411 same time as your kernel.
1414 The new pmtimer device is necessary for laptops. Failure to
1415 include the device will cause suspended laptops losing time
1416 when they resume. Include
1418 in your config file and
1419 hint.pmtimer.0.at="isa"
1420 to your /boot/device.hints file.
1423 The random device has been turned into a (pseudo-)device,
1424 rather than an option. The supplied kernel config files have
1425 been updated. You will need to do something similar in your
1426 own kernel config file.
1431 If you prefer to load the loadable module, you need to do
1435 The random device module has been renamed from randomdev.ko to
1436 random.ko. You will need to edit your /boot/loader.conf to
1437 reflect this if you load this module at boot time.
1438 The line should read:
1442 The SMPNG commit has happened. It should work, but if it
1443 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1444 to be a variety of minor issues. Please see 20000905 to make
1445 sure you don't have model loading problems which might at
1446 first blush appear related to SMP.
1449 nsswitch has been imported from NetBSD. Among other things,
1450 this means that /etc/host.conf is no longer used. See
1451 nsswitch.conf(5) instead. Note that at boot time rc.network
1452 will attempt to produce a new nsswitch.conf file for you if you
1453 don't have one, and you have host.conf.
1456 The ucred structure changed size. This breaks the interface
1457 that mountd uses. Trying to use an older mountd with a newer
1458 kernel guarantees a panic. This means that you need to use
1459 kernels newer than today only with matching mountd, but you
1460 needed to do that anyway with the boot loader changes.
1463 The boot loader has been updated. The new default kernel is
1464 now /boot/kernel/kernel.ko. The new default module location
1467 You *MUST* upgrade your boot loader and kernel at the same time.
1468 The easiest way to do this is to do the buildworld/buildkernel/
1469 installkernel/installworld dance.
1471 Furthermore, you are urged to delete your old /modules directory
1472 before booting the new kernel, since kldload will find stale
1473 modules in that directory instead of finding them in the correct
1474 path, /boot/kernel. The most common complaint that this cures
1475 is that the linux module crashes your machine after the update.
1477 if [ ! -d /boot/kernel.old ]; then
1478 mv /modules.old /boot/kernel.old
1479 chflags noschg /kernel.old
1480 mv /kernel.old /boot/kernel.old/kernel.ko
1481 chflags schg /boot/kernel.old/kernel.ko
1485 A new issue with the sendmail upgrade has come to light.
1486 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1487 incorrectly install the default aliases in /etc/mail rather than
1488 move the old one from /etc. So you'll need to manually move the
1489 file, create a symbolic link, remove the old /etc/aliases.db and
1490 run newaliases. For safety sake, you should stop sendmail
1491 while doing this and run the upgrade when locally sourced email
1492 is not likely to be generated.
1495 /boot/device.hints is now required for installkernel to
1496 succeed. You should copy GENERIC.hints for your architecture
1497 into /boot/device.hints. If and only if you compile hints
1498 into your kernel, then this file may be empty. Please note,
1499 if you have an empty or missing /boot/device.hints file and
1500 you neglected to compile hints into your kernel, no boot
1501 messages will appear after the boot loader tries to start the
1505 If you do NOT have ``options RANDOMDEV'' in your kernel and
1506 you DO want the random device then add randomdev_load="YES" to
1510 suidperl is now always built and installed on the system, but
1511 with permissions of 511. If you have applications that use
1512 this program, you are now required to add ENABLE_SUIDPERL=true
1513 to /etc/make.conf. If you forget to do this,
1514 chmod 4511 /usr/bin/suidperl
1515 will fix this until the next build.
1518 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1519 visible changes that may immediately affect your configuration
1521 - New default file locations from src/contrib/sendmail/cf/README
1522 - newaliases limited to root and trusted users
1523 - MSA port (587) turned on by default
1524 - New queue file naming system so can't go from 8.11 -> 8.9
1525 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1526 - FEATURE(`nullclient') is more full featured
1527 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1528 - mail.local FreeBSD-only -b option changed to -B
1529 - See src/contrib/sendmail/RELEASE_NOTES for more info
1532 suidperl (aka sperl) is no longer build by default. You must
1533 specifically define BUILD_SUIDPERL to "true" for it to be build.
1534 Furthermore, we recommend that you remove /usr/bin/sperl* and
1535 /usr/bin/suidperl files from your system unless you have a
1536 specific use for it.
1539 Networking defaults have been tightened. Anybody upgrading
1540 /etc/defaults/rc.conf needs to add the following lines to
1541 /etc/rc.conf if they want to have the same setup
1542 afterwards (unless the variables already are set, of course):
1543 # Enable network daemons for user convenience.
1545 portmap_enable="YES"
1546 sendmail_enable="YES"
1549 If you have null_load="YES" in your /boot/loader.conf, you
1550 will need to change that to nullfs_load="YES".
1553 The "installkernel" target has changed slightly. Now even if
1554 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1555 it will install the MYKERNEL file (built with the buildkernel
1556 target) as /kernel rather than /MYKERNEL. Those who have
1557 updated their /boot/loader.conf files to point to /MYKERNEL
1558 should remove that entry or perform manual rename of /kernel
1562 If you use CVSUP or CTM to get CVS trees, AND you used to get
1563 the old crypto files from internat.freebsd.org AND you check
1564 out files from the CVS tree with the cvs command, please read
1565 http://people.freebsd.org/~imp/internat.txt
1566 for details on potential problems that you might have and how
1569 If you are merely a mirror, or don't answer yes to each of the
1570 clauses above, you needn't worry.
1573 /etc/security has been updated to print the inode number of
1574 setuid programs that have changed. You will see a large spike
1575 in the number of changed programs the first time when you run
1576 mergemaster to get a new /etc/security.
1579 /dev/random now has good entropy collection (from the keyboard
1580 and sysmouse drivers). Please ensure that either `options
1581 RANDOMDEV' is present in your kernel config file or that
1582 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1583 not have the /dev/random driver, OpenSSL (and consequently
1584 lots of crypto tools (like SSH)) will fail with strange
1585 errors. (see below, 20000624).
1587 FreeBSD-current is safe again to run Crypto.
1590 phk made the malloc default options AJ. This may slow things
1591 down and uncover other latent bugs in the code. If you need to
1592 run at full speed, you can disable this by doing the following:
1593 ln -s aj /etc/malloc.conf
1596 libftpio's version was accidentally bumped a few days ago. This
1597 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1598 before doing your next buildworld/installworld pair. It certainly
1599 won't hurt to remove it before the update procedure. It will
1600 break fetch until a new one is built, but ftp can be used in the
1604 The crypto packages have changed for the cvsup. This has been done
1605 in a backward compatible way, but the old packages will go away at
1606 some point in the future. Look at /usr/share/examples/cvsup for
1610 With the new sys/modules/sound/drivers/*, you will need to
1611 set SYSDIR until you do an installworld after July 7th.
1614 rc.shutdown and rc will now call the rc.d scripts with start
1615 or stop. This may cause some harmless warnings from older
1616 rc.d scripts that haven't been updated.
1619 The libfetch based version of fetch has gone into the tree.
1620 Minor problems may result on some of the less popular sites,
1621 which should be reported to des@freebsd.org.
1624 From approximately this date forward, one must have the crypto
1625 system installed in order to build the system and kernel.
1626 While not technically strictly true, one should treat it as
1627 required and grab the crypto bits. If you are grabbing CVS
1628 trees, src-all and cvs-crypto should be treated as if they
1629 were required. You should check with the latest collections
1630 to make sure that these haven't changed.
1633 Mark Murray just committed the first parts of a cleanup of
1634 /dev/zero, et al. This is also cleaning up /dev/random.
1635 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1636 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1637 until Mark can merge in the fixes to this work in progress.
1638 openssh and openssl should not be used to generate keys from this
1639 date to the completion of the work.
1641 If you must operate at this reduced level of security, add '
1642 options RANDOMDEV' to your kernel or modload the randomdev
1643 module. You may also need to copy a new MAKEDEV to /dev and
1644 recreate the random and urandom devices.
1647 The license on the softupdates is now a standard 2 clause
1648 BSD license. You may need to remove your symbolic links
1649 that used to be required when updating.
1652 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1653 the config file update procedure.
1654 http://people.freebsd.org/~imp/config-upd.html
1655 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1656 isn't buildable. However, you can generate a LINT file:
1657 cd /sys/<ARCH>/conf && make LINT
1660 Binutils 2.10 have hit the tree, or will shortly. As soon
1661 as they do, the problem noted in 20000522 will be resolved and
1662 that workaround will no longer be required.
1665 phk removed the compatibility creation of wd devices in the
1666 ad driver. If you haven't done so already, you must update
1667 your fstab, etc to use the ad devices instead of the wd
1670 In addition, you'll need to update your boot blocks to a
1671 more modern version, if you haven't already done so. Modern
1672 here means 4.0 release or newer (although older releases
1676 Peter took an axe to config(8). Be sure that you read his mail
1677 on the topic before even thinking about updating. You will
1678 need to create a /boot/device.hints or add a hints directive
1679 to your config file to compile them in statically. The format
1680 of the config file has changed as well. Please see GENERIC or
1681 NEWCARD for examples of the new format.
1683 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1684 says that it has been fixed, assume that must use the hints mechanism
1685 in the loader if you need to use a machine with very old ISA cards
1689 A new set of binutils went into the tree today. Anybody
1690 building a kernel after this point is advised that they need
1691 to rebuild their binutils (or better yet do a
1692 buildworld/installworld) before building a new kernel.
1694 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1695 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1696 is recommended that you don't set this option until the problem
1700 The ethernet drivers were all updated to clean up the BPF handling.
1703 The problems with boot blocks on the alphas have been corrected.
1704 This will require some care in updating alphas. A new libstand
1705 is requires for the boot blocks to build properly.
1708 Recompile all kld modules. Proper version dependency info
1712 Modules have been disconnected from the buildworld tree and
1713 connected to the kernel building instead.
1716 You may need to build gperf
1717 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1718 when upgrading from 4.0 -> current. The build system now uses
1719 an option only in -current.
1722 The method that we brand ELF binaries has changed to be more
1723 acceptable to the binutils maintainers. You will need to
1724 rebrand your ELF binaries that aren't native. One problem
1725 binary is the Linux ldconfig. After your make world, but
1726 before you reboot, you'll need to issue:
1727 brandelf -t Linux /compat/linux/sbin/ldconfig
1728 if you have Linux compatibility enabled on your machine.
1731 If you have really bad/marginal IDE drives, you may find they
1732 don't work well. Use pio mode instead. The easiest way to
1733 cope if you have a problem combination is to add:
1734 /sbin/sysctl hw.ata.ata_dma=0
1735 to the start of /etc/rc.conf.
1738 The ISA and PCI compatibility shims have been connected to the
1739 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1740 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1741 include the appropriate option in your kernel config. Drivers
1742 using the shims should be updated or they won't ship with
1743 5.0-RELEASE, targeted for 2001.
1746 We've entered the traditional post release dumping party.
1747 Large kernel changes are being committed and are in the
1748 works. It is important to keep the systems' klds and kernel
1749 in sync as kernel interfaces and structures are changing.
1750 Before reporting kernel panics, make sure that all modules
1751 that you are loading are up to date.
1754 If you are upgrading from an older version of FreeBSD, you
1755 need to update your boot blocks as well. 'disklabel -B ad0'
1756 will do the trick. This isn't critical until you remove your
1757 wd device entries in /dev, at which point your system will not
1761 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1762 to upgrade to 4.0 from 3.x.
1766 # NOTE: 5.x below applies to 6.0-currrent as well, for the
1767 # momemnt. 4.any -> 5.any upgrade support will remain in
1768 # place for 6.0 current, but after 5.3 RELEASE, the 4.any ->
1769 # 6.0-current upgrade path will require moving through 5.3
1774 Avoid using make -j when upgrading. From time to time in the
1775 past there have been problems using -j with buildworld and/or
1776 installworld. This is especially true when upgrading between
1777 "distant" versions (eg one that cross a major release boundary
1778 or several minor releases, or when several months have passed
1779 on the -current branch).
1781 Sometimes, obscure build problems are the result of environment
1782 poisoning. This can happen because the make utility reads its
1783 environment when searching for values for global variables.
1784 To run your build attempts in an "environmental clean room",
1785 prefix all make commands with 'env -i '. See the env(1) manual
1786 page for more details.
1790 If you are updating from a prior version of FreeBSD (even one just
1791 a few days old), you should follow this procedure. With a
1792 /usr/obj tree with a fresh buildworld,
1793 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1794 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1796 To just build a kernel when you know that it won't mess you up
1797 --------------------------------------------------------------
1798 This assumes you are already running a 5.X system. Replace
1799 ${arch} with the architecture of your machine (e.g. "i386",
1800 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1802 cd src/sys/${arch}/conf
1803 config KERNEL_NAME_HERE

1881 Make sure that you've read the UPDATING file to understand the
1882 tweaks to various things you need. At this point in the life
1883 cycle of current, things change often and you are on your own
1884 to cope. The defaults can also change, so please read ALL of
1885 the UPDATING entries.
1887 Also, if you are tracking -current, you must be subscribed to
1888 freebsd-current@freebsd.org. Make sure that before you update
1889 your sources that you have read and understood all the recent
1890 messages there. If in doubt, please track -stable which has
1891 much fewer pitfalls.
1893 [1] If you have third party modules, such as vmware, you
1894 should disable them at this point so they don't crash your
1897 [2] If you have legacy ISA devices, you may need to create
1898 your own device.hints to reflect your unique hardware
1901 [3] From the bootblocks, boot -s, and then do
1906 adjkerntz -i # if CMOS is wall time
1907 Also, when doing a major release upgrade, it is required that
1908 you boot into single user mode to do the installworld.
1909 For the 4.x -> 5.x upgrade, you will also see many messages about
1910 needing to recompile your userland. These are harmless and can
1911 be ignored while you proceed to the next step.
1913 [4] Note: This step is non-optional. Failure to do this step
1914 can result in a significant reduction in the functionality of the
1915 system. Attempting to do it by hand is not recommended and those
1916 that pursue this avenue should read this file carefully, as well
1917 as the archives of freebsd-current and freebsd-hackers mailing lists
1918 for potential gotchas.
1920 [5] Usually this step is a noop. However, from time to time
1921 you may need to do this if you get unknown user in the following
1922 step. It never hurts to do it all the time. You may need to
1923 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1924 install) after the buildworld before this step if you last updated
1925 from current before 20020224 or from -stable before 20020408.
1927 [6] 4.x boot loader can be used to boot a 5.x system, however
1928 it is difficult to do that at best. If you wish to try, then
1929 you should interrupt the boot and at the ok prompt type:
1931 ok boot /boot/kernel/kernel
1932 If this fails to work, you must install a new boot loader as
1935 [7] Before you upgrade, please make sure that you are not using
1936 compatibility slices. These are device names of the form /dev/ad0a
1937 without the actual slice name. These will break with 5.x and newer.
1938 You generally must update these entries to use the post FreeBSD
1939 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha
1942 [8] In order to have a kernel that can run the 4.x binaries
1943 needed to do an installworld, you must include the COMPAT_FREEBSD4
1944 option in your kernel. Failure to do so may leave you with a system
1945 that is hard to boot to recover.
1947 Make sure that you merge any new devices from GENERIC since the
1948 last time you updated your kernel config file.
1950 [9] When checking out sources, you must include the -P flag to have
1951 cvs prune empty directories.
1953 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1954 "?=" instead of the "=" assignment operator, so that buildworld can
1955 override the CPUTYPE if it needs to.
1957 MAKEOBJDIRPREFIX must be defined in an environment variable, and
1958 not on the command line, or in /etc/make.conf. buildworld will
1959 warn if it is improperly defined.
1961 In case you would like to avoid installing new packages of everything,
1962 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1963 compatibility libraries are built which should allow you to continue
1964 using your existing software for a while. Alternatively, you can
1965 install the misc/compat4x port.
1967 [10] In order to create temporary files, /dev/random must be
1968 initialized by feeding data into it. src/etc/rc.d/preseedrandom
1972 This file contains a list, in reverse chronological order, of major
1973 breakages in tracking -current. Not all things will be listed here,
1974 and it only starts on March 15, 2000. Updating files can found in
1975 previous releases if your system is older than this.
