11 NOTE TO PEOPLE WHO THINK THAT FreeBSD 5.x IS SLOW:
12 FreeBSD 5.x has many debugging features turned on, in
13 both the kernel and userland. These features attempt to detect
14 incorrect use of system primitives, and encourage loud failure
15 through extra sanity checking and fail stop semantics. They
16 also substantially impact system performance. If you want to
17 do performance measurement, benchmarking, and optimization,
18 you'll want to turn them off. This includes various WITNESS-
19 related kernel options, INVARIANTS, malloc debugging flags
20 in userland, and various verbose features in the kernel. Many
21 developers choose to disable these features on build machines
22 to maximize performance.
25 making /dev/(null|zero) into a module proved to be too unpopular,
26 so this bit has been revoked from the previous (20040801) entry.
29 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
30 so you may wish to add them to your kernel config file. See
34 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
35 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
36 has broken C++ ABI compatibility with previous releases yet again
37 and users will have to rebuild all their C++ programs with the new
38 compiler. A new unit-at-a-time optimization mode, which is default
39 in this compiler release, is more aggressive in removing unused
40 static symbols. This is the likely cause of 'make buildworld'
41 breakages with non-default CFLAGS where optimization level is set
45 The size of 'struct ifnet' has changed due to the addition of
46 the IFF_NEEDSGIANT flag (and what it implies). All kernel
47 modules implementing network interfaces must be recompiled as
51 The sound device drivers are renamed. `sound' is always required,
52 while `snd_*' should be configured accordingly to your hardware.
53 Refer to NOTES for the detail of the drivers.
56 __FreeBSD_version bumped to 502122.
59 The console initialization on Alpha has been reworked and is now
60 identical to other platforms. This means that the hardcoding of
61 the serial console and the debug port has been removed. As such,
62 hints are now required for the sio(4) driver to become a console
63 or debug port. The NO_SIO option has been decommissioned because
67 A revamp of the debugging code in the kernel with some visible
68 changes beyond just the debugging experience:
69 o The DDB option is now specific to the DDB debugger backend
70 and should not be used any more for conditional compilation
71 of debugging code for when debugging is enabled. Use the KDB
73 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
74 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
75 respectively. This is in line with the first bullet.
76 o The remote GDB support has been untangled from DDB and needs
77 to be enabled separately now. Use the GDB option for this.
78 o The GDB_REMOTE_CHAT option has been removed. Support for this
79 homegrown feature is discontinued. The GDB remote protocol
80 supports console output and it makes sense to use that.
81 o The DDB_NOKLDSYM option has been removed. The DDB debugger
82 now supports both direct symbol table lookups as well as KLD
83 symbol lookups through the linker.
86 Bluetooth code has been marked as non-i386 specific.
87 __FreeBSD_version has been bumped to 502121 to mark this change.
90 The native preemption has been added to the kernel scheduler.
91 There is some report that the ULE scheduler was broken in some
92 machines and we encourage users using the ULE scheduler either
93 stick with a known good kernel, or temporarily switch to the 4BSD
94 scheduler as a workaround.
97 The netgraph ABI version number has been incremented to indicate
98 an incompatible change in the ABI. Old netgraph nodes will refuse
99 to attach until recompiled. Netgraph now uses mbuf tags to move
100 metadata and this commit removes its home-grown metadata facility.
101 Nodes should just recompile, unless they use metadata, in which
102 case the changes are simple; the file ng_ksocket.c serves as an
103 example of such changes.
105 This also broke i4b, although the compile problem has been papered
109 ACPI has been updated to disable known-bad BIOS revisions. A message
110 will be printed on the console indicating that ACPI has been disabled
111 automatically and that the user should use a newer BIOS, if possible.
112 If you think ACPI does work on your system and want to override
113 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
117 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
118 separated now. It uses the newly created "_pflogd" user/group
119 combination. If you plan to use pflogd(8) make sure to run
120 mergemaster -p or install the "_pflogd" user and group manually.
123 Network interface cloning has been overhauled. This change will
124 require a recompile of modules using cloning and modification of
125 external ones to the new API. __FreeBSD_version has been bumped
126 to 502119 to mark this change. Additionally, users creating
127 stf(4) interfaces via "ifconfig stf" will need to update their
128 scripts as this will create an interface named "stf" instead of
129 "stf0" and ifconfig will not print "stf0" to stdout.
132 On 20040524, the /etc/rc.d/nsswitch script was modified to
133 automatically create /etc/nsswitch.conf on startup if it did
134 not already exist. Unfortunately, an error in the man page
135 was carried over to the script, resulting in incorrect
136 nsswitch settings. The simplest remedy is to remove both
137 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
138 during the next reboot.
141 The return value of sema_timedwait(9) has been changed to
142 make it consistent with cv_timedwait(9). Be sure to recompile
143 the ips module and any third-party modules which call
147 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
148 Make sure to recompile modules and any userland that makes use of
149 sizeof(struct ifnet). In order to get the altq headers in place
150 please recompile and reinstall world.
153 Splitting kern_thread.c into 2 files (adding kern_kse.c)
154 requires that you re-run config after updating your tree.
157 The MIDI drivers have been removed. Until the new module-friendly
158 ones are merged, remove or comment out midi and seq from your
159 kernel configuration.
162 Due to a new option in ipfw (versrcreach) the ipfw(8) command
163 needs to be recompiled. Normal accept/reject rules without
164 options are not affected but those with options may break until
165 ipfw(8) is recompiled.
168 Due to changes in the callout ABI, kernels compiled after this
169 date may be incompatible with kernel modules compiled prior to
173 The PCI bus power state stuff has been turned on. If this causes
174 problems for your system, please disable it using the tunable
175 hw.pci.do_powerstate=0.
178 The bulk of the pci problems have been fixed, although the floppy
179 drive is still broken.
182 A substantial update to the pci bus resource and power management
183 have been committed. Expect a bumpy ride for a few days until
184 the unanticipated problems have been resolved.
187 Due to changes in the the Yarrow initialization process,
188 /dev/random needs to be fed before operations requiring
189 temp files can succeed in single user mode. This includes
190 running "make installworld". /dev/random may be fed by running
191 "/etc/rc.d/initrandom start" or with 20040415 source by running
192 "/etc/rc.d/preseedrandom".
195 The debug.mpsafenet tunable controls whether the kernel Giant
196 lock is held across the lower levels of the network stack, and
197 by default is turned off. In the few days following 20040322,
198 the behavior of debug.mpsafenet will change such that this
199 tunable controls Giant over all levels of the network stack.
200 If you are currently setting debug.mpsafenet to 1, you should
201 set it back to 0 (the default) again during the change-over.
202 An additional note will be added to UPDATING when sufficient
203 locking is merged to permit this to take place.
206 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
207 64-bits. This is a very major incompatible change, so people
208 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
209 detailed instructions on how to make this upgrade. People
210 upgrading FreeBSD on other platforms can ignore this event.
213 The packet filter (pf) is now installed with the base system. Make
214 sure to run mergemaster -p before installworld to create required
215 user account ("proxy"). If you do not want to build pf with your
216 system you can use the NO_PF knob in make.conf.
217 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
218 pf system consists of the following three devices:
220 device pflog # optional
221 device pfsync # optional
224 If you are having trouble with the libc_r -> libpthread transition
225 (see the 20040130 entry), place the following lines at the top of
228 libc_r.so.5 libpthread.so.1
229 libc_r.so libpthread.so
231 This will cause all programs and libraries linked against libc_r
232 to use libpthread instead.
235 Some sshd configuration defaults have changed: protocol version 1
236 is no longer enabled by default, and password authentication is
237 disabled by default if PAM is enabled (which it is by default).
238 OpenSSH clients should not be affected by this; other clients may
239 have to be reconfigured, upgraded or replaced.
242 The ABIs defined in <resolv.h> and <netdb.h> have been updated
243 to support improved reentrancy. Multi-threaded programs that
244 reference the "_res" or "h_errno" symbols may experience some
245 problems if they are not recompiled. Single-threaded programs
246 should remain unaffected.
249 routed has been updated in the base system from the vendor
250 sources, routed v2.27, from rhyolite.com. This change means that
251 for users who use RIP's MD5 authentication feature, FreeBSD
252 -CURRENT's routed is now incompatible with previous versions
253 of FreeBSD; however it is now compatible with implementations
254 from Sun, Cisco and other vendors.
257 The tcpcb structure has changed and makes a recompile of libkvm
258 and related userland network utilities necessary.
261 The cdevsw structure has changed in two externally visible ways.
262 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
263 Second, the d_version field must be filled in with D_VERSION.
264 Drivers outside the tree will need to be updated.
267 The /etc/rc.d/ttys script has been removed. It is no longer
268 necessary since devfs has been mandatory for some time.
271 libkse has been renamed back to libpthread and is now the
272 default threads library. The gcc -pthread option has also
273 been changed to link to libpthread instead of libc_r. For
274 alpha and sparc64 machines, libkse is not renamed and links
275 are installed so that libpthread points to libc_r. Until
276 the ports system is updated to handle this change, it is
277 recommended that folks install an /etc/libmap.conf(5) that
278 maps libc_r to libpthread. If you have any binaries or
279 libraries linked to libkse, then it is also recommended
280 that you map libkse to libpthread. Anyone that is using
281 nvidia supplied drivers and libraries should use a libmap.conf
282 that maps libpthread to libc_r since their drivers/libraries
283 do not work with libpthread.
286 ULE has entered into its probationary period as the default scheduler
287 in GENERIC. For the average user, interactivity is reported to be
288 better in many cases. On SMP machines ULE will be able to make more
289 efficient use of the available parallel resources. If you are not
290 running it now, please switch over, replacing the kernel option
291 SCHED_4BSD with SCHED_ULE.
294 Move LongRun support out of identcpu.c, where it hardly
295 belongs, into its own file and make it opt-in, not mandatory,
296 depending on CPU_ENABLE_LONGRUN config(8) option.
299 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
300 if the login process is unable to successfully set the
301 process credentials to include all groups defined for the
302 user. The current kernel limit is 16 groups; administrators
303 may wish to check that users do not have over 16 groups
304 defined, or they will be unable to log in.
307 The ACPI module has been reactivated. It is no longer required
308 to compile ACPI support into kernels statically.
311 The statfs structure has been updated with 64-bit fields to
312 allow accurate reporting of multi-terabyte filesystem
313 sizes. You should build world, then build and boot the new kernel
314 BEFORE doing a `installworld' as the new kernel will know about
315 binaries using the old statfs structure, but an old kernel will
316 not know about the new system calls that support the new statfs
318 Note that the backwards compatibility is only present when the
319 kernel is configured with the COMPAT_FREEBSD4 option. Since
320 even /bin/sh will not run with a new kernel without said option
321 you're pretty much dead in the water without it. Make sure you
322 have COMPAT_FREEBSD4!
323 Running an old kernel after a `make world' will cause programs
324 such as `df' that do a statfs system call to fail with a bad
325 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
326 that cfsd (ports/security/cfs) needs to be recompiled after
327 these changes are installed.
329 ****************************DANGER*******************************
331 DO NOT make installworld after the buildworld w/o building and
332 installing a new kernel FIRST. You will be unable to build a
333 new kernel otherwise on a system with new binaries and an old
337 Some netgraph string length constants have been changed. This
338 change requires the netgraph kernel modules and all netgraph
339 userland components to be in sync. Especially users who require
340 netgraph to boot need to make sure to have world and kernel in
341 sync before rebooting.
344 Hyperthreading logical CPU's are no longer probed by default
345 when using the MP Table. If ACPI is being used, then logical
346 CPUs will be probed if hyperthreading is enabled in the BIOS.
347 If ACPI is not being used and hyperthreading is enabled in the
348 BIOS, logical CPUs can be enabled by building a custom kernel
349 with the option MPTABLE_FORCE_HTT enabled.
352 The i386 APIC_IO kernel option has been replaced by
353 'device apic'. The ACPI module has also been temporarily
354 disabled, so ACPI must be statically compiled into your
355 kernel using 'device acpi' if you wish to use the ACPI driver.
358 The API and ABI of struct ifnet have been changed by removing
359 the if_name and if_unit members and replacing them with
360 if_xname, if_dname, and if_dunit. All network drivers and most
361 userland programs which include net/if_var.h must be updated
362 and recompiled. __FreeBSD_version has been bumped to 501113 to
366 Changes to the cdevsw default functions have been made to remove
367 the need to specify nullopen() and nullclose() explicitly.
368 __FreeBSD_version bumped to 501110.
371 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
372 mount_cd9660(8) need to be in sync with kernel.
375 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
376 also be explicitly configured. Previously this dependency was
377 magically handled through some cruft in net/pfil.h; but that has
378 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
379 will fail with obtuse errors in ip_fil.c.
382 Fix a bug in arplookup(), whereby a hostile party on a locally
383 attached network could exhaust kernel memory, and cause a system
384 panic, by sending a flood of spoofed ARP requests. See
385 FreeBSD-SA-03:14.arp.
388 A change to /etc/defaults/rc.conf now causes inetd to be started
389 with `-C 60' if it is not overridden in /etc/rc.conf. This
390 causes inetd to stop accepting connections from an IP address
391 that exceeds the rate of 60 connections per minute.
394 The following rc.d scripts have been removed and should be
395 deleted from your installation: atm2.sh atm3.sh devdb
396 localdaemons network1 network2 network3. Depending on when
397 you last updated world and used mergemaster(8) you may or
398 may not have problems during the rc boot sequence. The simplest
399 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
400 The atm2.sh atm3.sh and devdb scripts were removed some time
401 ago, so depending on when you installed -CURRENT these scripts
402 may or may not exist on your system.
405 ATAng has been committed. You need to build world as sys/ata.h
406 has changed, and userland atacontrol depends on it.
407 If you use ATA SW raids you need "device ataraid" in your
408 kernel config file, as it is no longer pulled in automatically.
411 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
412 Among other things, this changes the device enumeration to be
413 closer to Solaris. Be aware that, this can even cause the machine
414 to not boot without manual intervention before the fstab is adjusted.
417 All current USB and Firewire quirks in da(4) have been deprecated
418 and will be removed for 5.2. If this causes failure for your
419 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
420 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
421 so the quirk can be re-enabled.
424 Problems with entry 20030714 have been corrected and no known issues
425 with /rescue and -j exist for host systems after this point in time.
428 FPU-less support has been removed from FreeBSD. Chances are you won't
429 notice. 386+387 support should still work after this change, but
430 it is now a minimum requirement for the i386 port that you have real
434 Some people are having problems with changes related to /rescue.
435 If you are building -j N, you will need to define NO_RESCUE. Others
436 will need to define it if /rescue has issues with their environment.
437 People should report those issues to current@.
440 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
441 across this point. Further, it might be a good idea to remove
445 Remove deprecated locale names and transition period code
446 for them, finishing switching to the new scheme. Check your
447 LANG environment variable.
450 CCD has been changed to be a fully GEOMified class. Kernel
451 and ccdconfig(8) needs to be in sync, this is particularly
452 important to remember beforehand if your source tree is on
453 a ccd device. Consider making a copy of the old ccdconfig
454 into /boot/kernel.good or wherever you keep your backup
458 There was a small window in which sed(1) was broken. If you
459 happen to have sed(1) installed during that window, which is
460 evidenced by an inability to build world with the failure
461 given below, you need to manually build and install sed(1)
462 (and only sed(1)) before doing anything else. This is a one-
463 time snafu. Typical failure mode:
465 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
466 targmatch.h:7:1: null character(s) ignored
467 targmatch.h:12:1: null character(s) ignored
468 targmatch.h:16:1: null character(s) ignored
471 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
472 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
473 usr.bin/sed/process.c).
476 Kerberos 5 (Heimdal) is now built by default. Setting
477 MAKE_KERBEROS5 no longer has any effect. If you do NOT
478 want the "base" Kerberos 5, you need to set NO_KERBEROS.
481 groff has been updated. If you try to do a buildworld and
482 get an infinite loop in troff, update to May 4th or newer. If you
483 have a newer kernel than userland, you may need to set the OSRELDATE
484 to 500110 in your environment before starting a buildworld.
487 The old rc system has been removed. Please report any problems
488 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
489 Your personal versions of these files will not be removed, so you can
490 continue to use them. However, you should take great care when updating,
491 especially when using mergemaster, since the compatibility code that
492 utilizes these old scripts has also been removed.
495 A bug has been fixed in /dev/devctl which would cause devd
496 to hang on boot, were it not for a workaround in devd. The
497 work around in devd will be removed around 20030507. You
498 have until then to upgrade your kernel before updating
499 userland. In general, you should have a userland and
500 kernel that's in sync with each other. However, given the
501 effects of this bug (hang on boot when starting devd), some
505 Alphas with libc from between 20030312 and 20030329 exhibit
506 floating point exceptions (FPEs), most notably in awk(1)
507 while upgrading the system through a buildworld.
509 So, to successfully upgrade your Alpha, you must either
510 downgrade your libc.so to a pre-20030312 version, or update
511 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
512 to CFLAGS, then forcibly rebuild and install libc:
514 cd /usr/src/lib/libc && \
515 make cleandir && make obj && \
516 make -DNOMAN -DNOPROFILE all && \
517 make -DNOMAN -DNOPROFILE install
520 sendmail 8.12.7 has been imported. It has one important
521 change for IPv6 users. The default submit.mc now uses
522 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
523 used to connect to the MTA. Users on IPv6-only machines
524 will need to edit /etc/mail/submit.mc appropriately.
527 NODEVFS option has been removed and DEVFS thereby made standard.
528 This makes all references to MAKEDEV obsolete, and they should
529 be removed when convenient.
532 The name of the device for the ofw console has changed, sparc64 users
533 must run mergemaster to update their installed /etc/ttys.
536 The scheduler framework has grown a second scheduler and consequently
537 you must specify one and only one scheduler in your kernel config.
538 The cvs config files have been updated to use the old scheduler
539 which may be selected via 'options SCHED_4BSD'. If you would like
540 to try the new, much more experimental, scheduler please try
541 'options SCHED_ULE' and contribute to the arch@ discussion.
544 A new version of the wi driver has been imported into the tree.
545 One now must have device wlan in the config file for it to operate
548 In addition, there have been some changes to how wi devices are
549 configured for point to point links to bring it more in line
550 with the former way of doing things, as well as compatibility
554 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
555 used an incompatible form of ABI for returning structures and unions
556 which FreeBSD's GCC maintainers were not aware of relative to previous
557 versions of FreeBSD. We have gone back to the ABI for now, and any
558 code compiled which is required to interoperate with other code (not
559 built at the same time) returning structs or unions should be
563 A name change in /etc/netconfig has been reverted to stay
564 compatible with suns TIRPC and also with NetBSD. You need
565 to run mergemaster after make world. A new libc does still work
566 with an outdated /etc/netconfig for some time, but you'll get
567 a warning. This warning will be removed in 20030301.
570 The recent binutils upgrade marks a kernel flag day on
571 sparc64: modules built with the old binutils will not work
572 with new kernels and vice versa. Mismatches will result in
573 panics. Make sure your kernel and modules are in sync.
576 The value of IPPROTO_DIVERT has changed. Make sure to keep
577 your kernel, netstat, natd and any third-party DIVERT
581 Old, compatibility slices have been removed in GEOM kernels.
582 This means that you will have to update your /etc/fstab to
583 not use disk devices of the form /dev/ad0a. Instead, you
584 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
585 partition really is on. The old device names have gone
586 away, so if you use them anywhere else, you must also adjust
587 those uses. (This doesn't affect the disks formatted in
588 the ``dangerously-dedicated'' mode.)
591 Alphas with kernels from between 20020830 and 20021023 and/or
592 rtld (ld-elf.so.1) older than 20021023 may experience problems
593 with groff while doing a buildworld (kernel: "out of memory",
594 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
595 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
597 So, to successfully upgrade your Alpha, you must either
598 upgrade your kernel and rtld first (which might be a bit
599 tricky), or avoid running the bootstrapped groff during the
600 "transitional" buildworld. To avoid running groff during the
601 transitional upgrade run make buildworld with -DNOMAN,
602 -DNO_SHAREDOCS, and -DNO_LPR.
605 gcc has been upgraded to 3.2. It is not all binary compatible
606 with earlier versions of gcc for c++ programs. All c++
607 programs and libraries need to be recompiled.
609 Also, if you encounter g++ issues, rm /usr/include/g++/* before
610 doing an installworld to make sure that stale files are removed.
613 Our /etc/termcap now has all the entries from the XFree86 xterm
614 almost unchanged. This means xterm now supports color by default.
615 If you used TERM=xterm-color in the past you now should use
616 TERM=xterm. (xterm-color will lead to benign warnings).
619 A "bug" in gcc(1) that was hiding warning in system headers was
620 fixed. It's probably time to add -DNO_WERROR to your make line
624 COPY is being deprecated. The 20010530 change was reverted, as
625 it causes far more pain than was expected, and to always compare
626 before installing, please use INSTALL="install -C" again. The
627 -C option is now silently ignored when used with the -d option.
630 Problems with libc_r clients like KDE and GNOME have been resolved.
631 There are still some minor problems with some signals but the
632 system is stable enough for general use again. SMP is less so than UP
633 but each can successfully complete multiple buildworlds.
634 Libkvm needs to be recompiled due to KSE.
637 Now would be a bad time to upgrade. Something in or near the
638 KSE commit totally broke programs using libc_r like KDE and
642 The k5su utility installed as part of Kerberos 5 is no longer
643 installed with the set-user-ID bit set by default. Add
644 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
645 with the set-user-ID bit set.
648 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
649 Unfortunately our native GDB (at version 4.18) does not understand
650 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
651 generated debugging information for our native GDB.
654 Due to the way CVS works, it may not properly update src/contrib/gcc
655 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
656 and then do a cvs update.
659 When exec'ing set[ug]id executables, the kernel now ensures that the
660 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
663 New sendmail startup scripts have been installed to make it
664 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
665 variable sendmail_enable to "NO" no longer prevents any sendmail
666 daemons from starting. Instead, either set sendmail_enable to
667 "NONE" or change mta_start_script to a script for starting
668 an alternative MTA. Setting mta_start_script to "" will
669 also prevent any MTA from being started at boot.
672 UCONSOLE is no longer a valid kernel option.
675 FreeBSD 5.0 DP-1 was basically branched today.
678 Warnings are now errors in the kernel. Unless you are a developer,
679 you should add -DNO_WERROR to your make line.
682 sendmail 8.12.2 has been imported. The sendmail binary is no
683 longer a set-user-ID root binary and the infrastructure to support
684 command line mail submission has changed. Be sure to run
685 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
686 and /etc/mail) and read /etc/mail/README for more details.
688 Due to the import of sendmail 8.12.2, a new user and group are
689 required in order for sendmail to run as a set-group-ID
690 binary. A 'make installworld' will use the new user and group
691 to set the owner and group of /var/spool/clientmqueue and will
692 fail if the new user and group do not exist. The 'smmsp' user
693 and group must be merged from src/etc/group and
694 src/etc/master.passwd before using 'make installworld'.
695 'mergemaster -p' will do this. You may need to install
696 mergemaster before this will work if you are updating from a
697 very old version of current. The updating recipe has changed
701 The preferred configuration method for PAM is now /etc/pam.d/
702 rather than /etc/pam.conf. If you have an unmodified
703 pam.conf, just delete it after your next mergemaster run. If
704 you have local modifications, you can use
705 /usr/src/etc/pam.d/convert.pl to incorporate them into your

716 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
717 started out its life in the ISDN4BSD project as an offspring
718 from sys/net/if_spppsubr.c, which eventually got a life of its
719 own. All the accumulated features and bug fixes of the i4b
720 version have now been merged back into the base system's
721 version now. The only user-visible change resulting from this
722 is that i4b's sppp(4) interfaces are to be managed with
723 spppcontrol(8) again, since ispppcontrol(8) has been retired
724 as well. (There has never been rc file support for
725 ispppcontrol in -current, but only in -stable. That will be
726 reverted by the time the changes are MFCed.)
729 The fdc(4) driver has been updated and now automatically
730 recognizes media in `standard' formats (like 1440 KB and
731 720 KB for a 3.5" high-density drive) when accessing the
732 default device node (e. g. /dev/fd0). The old variety of
733 floppy device nodes /dev/fd*.* is no longer present by
734 default, devices can be created (in DEVFS) on demand. They
735 will need to be customized then for `odd' densities using
739 The bugs in procfs' debugging support code have been fixed,
740 and truss(1) now works again.
743 Daily security checks have been split out to use the periodic(8)
744 scripts. Some change in configuration may be necessary. Please
746 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
750 sos added VCD/SVCD support to ata driver and that needs the
751 kernel and burncd to be in sync.
754 The procfs pseudo-filesystem has now been converted to use the
755 pseudofs framework. If you have 'options PROCFS' in your
756 kernel config, you'll need to add 'options PSEUDOFS' if it's
759 This change temporarily breaks truss(1); use ktrace(1) instead
760 until the issue has been resolved.
763 A security hole in OpenSSH involving `UseLogin yes' has been
767 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
768 after this date. You need to do this only once.
771 Most of the awk issues have been resolved. Some rough
772 edges may be left, but for the most part things should be
773 back to "normal." For CURRENT's usual definition of "normal."
776 Awk has been upgraded to the one true awk from bell labs. Expect
777 choppy waves in the upgrade process.
780 The asr driver problem has been resolved.
783 Due to changes in other parts of the system, the asr driver
784 now causes the system to panic on boot. Do not use it pending
785 correction. Comment it out of any kernel config file that you
786 try to use from this date forward.
789 When crossbuilding, use TARGET=xxx where you used to use
790 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
791 unless you are changing both of them. To cross build pc98 on
792 an alpha, for example, you need to set TARGET=pc98 and
796 The kernel interface that burncd depends on has changed.
797 You must recompile both the kernel and userland applications
801 When crossbuilding, please set TARGET_ARCH rather than
802 MACHINE_ARCH to indicate the target. In the future, one will
803 set TARGET_MACHINE where you set MACHINE now. At the moment,
804 setting MACHINE alone for same MACHINE_ARCH machines works
805 (eg, you can build pc98 on an i386 machine and vice versa).
808 Some weird problems result from using ACPI on some machines.
809 To disable ACPI you can add
810 hint.acpi.0.disabled="1"
811 to /boot/loader.conf (or by putting set X=Y at the boot
814 Alternatively, you can remove it from /boot/kernel/acpi.ko
815 or use the MODULES_OVERRIDE function in your kernel config
816 file and not list acpi in that list.
819 The buildworld has been fixed. You may need to install
820 the 4.x compatibility libraries for some old binaries
821 to work. Add COMPAT4X=true to your /etc/make.conf to
822 get them installed on every installworld, or execute the
823 following to get them installed only once:
824 cd src/lib/compat/compat4x.<arch>
826 You will see ``__stdoutp undefined'' until you do this.
829 There's a bug in the world build process. The cross-tools
830 are build with the NEW headers, but the OLD libc.a. This
831 leads to all kinds of problems with the new libc. A temporary
833 CFLAGS="-O -pipe -D_OLD_STDIO"
834 before building world when upgrading from 4.x to current. This
835 can be removed afterwards.
837 A proper fix to the buildworld target is needed.
840 Peter has committed his new kthread nfs client/server code.
841 NFS may be unstable after this date.
844 KSE has hit the tree. Lots of things are now different in
845 the kernel. While a few problems were introduced in the
846 initial commit, most of the major ones have been found and
850 In OLDCARD, CardBus bridges appear to be stable. The work
851 arounds described in the 20010604 entry are now no longer
852 necessary and will be ignored. Most insert/remove problems
853 have been rectified around this date.
856 named now runs as user bind and group bind rather than as
857 root. If named_enable is set to YES in /etc/rc.conf, ensure
858 that user bind is available in /etc/passwd (using vipw(8))
859 and that group bind is available in /etc/group. Also make
860 sure that user or group bind has read (and not write)
861 permission for your name server configuration and that it
862 has read and write permission for your slave zone files and
865 If you wish to continue to run named as root (a less secure
866 alternative), add a line to /etc/rc.conf saying
871 The PAM libraries have had an API upgrade that is beyond
872 the ability of the shared library major number to handle.
873 It is manifested by PAM-using ports dumping core. The
874 solution is to rebuild those ports.
877 The kernel compile module has moved from src/sys/compile/FOO
878 to src/sys/${MACHINE}/compile/FOO.
881 The pccard modem issue from 20010613 has been corrected.
882 OLDCARD support is still a little weak in -current. slot 1 is
883 known not to work on some TI based cardbus bridges. Some
884 cardbus bridges do not properly detect insert/removal events.
885 IRQ configuration needs more safety belts.
888 Softupdates problems have been corrected.
891 Peter ripped out the linkerset support. You must, as always,
892 rerun config after you cvsup if you are using the traditional
893 kernel building methods.
896 pccard modems may not work with current after 20010604 date. Some
897 do, others result in panics. *MAKE*SURE* that you update your
898 config and /etc/rc.conf ala the 20010604 entry, or you will have
899 problems (this issue will be fixed, it just hasn't been yet).
902 SOFTUPDATES seem to be broken since the middle of May or so. Do not
903 use them in current. You can disable softupdates on all mounted
904 partitions, or remove SOFTUPDATES the kernel config file.
907 After Peter's commits to the hints code, people have been noticing
908 that certain devices are attached (or try to) twice. This is due
909 to having both static hints as well as a /boot/device.hints. To
910 work around this issue, please use only one or the other mechanism
911 until this bug is fixed.
913 Please note that a feature of config is that if you have config
914 file FOO and FOO.hints, it automatically adds FOO.hints to the
915 hints.c file, whether you want it to or not.
918 Locale names have changed to match other systems better.
921 pccard support for pci cards has been committed. You must change
922 your /etc/pccard.conf irq lines. It must match the irq used by
923 pcic device. Interrupt storms may result if you fail to do this.
924 Interrupt storms look a lot like a hang.
926 You must also install a new pccardd, otherwise you will get an
927 interrupt storm at card reset time (just after it tells you what
930 pccardd_flags="-I" is necessary for the time being. It tells pccardd
931 not to ask the kernel if the interrupt is really free or not before
932 using it. You can either change the /etc/pccard.conf irq lines to
933 match pcic, or add "-i X" to the pccardd_flags.
936 INSTALL=install -C is being deprecated. If you want to do this,
937 use COPY=-C instead. The former method will be supported for only
938 a limited time. If you see
940 install: warning: the -d and -C options may not be specified together
942 in your makeworld, then you need to migrate towards using
946 It appears that vm is now stable enough to use again. However,
947 there may be other problems, so caution is still urged. alpha
948 definitely is in bad shape.
951 Minor repo damage has happened. This may cause problems
952 with cvsup of ports. If you get errors, please see
953 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
954 at the bottom for details on a workaround. The error message
956 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
959 Vm and/or swapping are busted on -current. Please be patient.
962 pccard has had much reorganizational work done to it over
963 the past few days. Everything should still work, but if
964 not, please contact imp@freebsd.org.
967 ata ioctl changed. Make sure to recompile both kernel and
968 userland at the same time.
971 New ncurses imported.
974 DEVFS is now opt out, not opt in. Barring major problems, this
975 will be the only way to go starting July 1.
978 OpenSSH has been updated to 2.9. Some defaults are different,
979 including RhostsRSAAuthentication, which changes from yes to no.
982 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
985 Building perl was broken at 02:25:25 PDT.
988 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
989 go back in the water.
992 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
993 this date, but before the correction date.
996 old fsck and new kernel interactions appear to have been fixed.
999 fsck and the kernel were changed to handle some optimizations
1000 to directory layout. This breaks backward compatibility.
1001 Update only if you understand that you must not use the old
1002 fsck with the new kernel ever.
1005 fsck has changed the meaning of the pass column in /etc/fstab.
1006 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1007 details. It is unclear if changes to /etc/fstab are necessary.
1010 portmap had changed name to rpcbind for maximum POLA in your
1011 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1012 other rpc based programs that rely on portmapper will not work
1013 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1016 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1017 and ATA_ENABLE_TAGS are no longer kernel options. They have
1018 been replaced by tunables. See ata.4 for details.
1021 The fxp driver was converted to use miibus. If you compile
1022 fxp into your kernel statically, you will need to add miibus.
1025 The wi device now defaults to BSS (infrastructure) mode
1029 /dev/urandom should be a symbolic link to /dev/random now.
1030 Users of current not using DEVFS need to run MAKEDEV std.
1031 ssh might not work if you don't.
1034 The ed driver has been updated. It now allows mii attachments,
1035 which means that you must include the miibus in your kernel if
1036 you use the ed driver.
1039 The problems with libc have been corrected. It is now mostly
1040 safe to go back into the water.
1043 The size of FILE was changed. This breaks upgrading. If
1044 you must upgrade, be prepared for pain. It also breaks almost
1045 all binaries that you've compiled on -current. You are warned
1046 that before upgrading would be a good time to do a level 0
1047 dump of your system. No, really, I mean it this time.
1049 To get to the new system, you'll need to use the following
1050 workaround. Hopefully this can be sorted out so that we
1051 don't have to move this to the updating section.
1053 To get around the installworld problem, do:
1054 # cd /usr/src/usr.bin/sed
1058 If that doesn't work, then try:
1059 # make -k installworld
1063 DEVFS is now the default. If you use vinum, make sure that you
1064 do not include devfs in your kernel as problems result.
1067 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1068 Remove them from your config.
1071 ****************************** WARNING ******************************
1072 buildkernel has been changed slightly
1073 ****************************** WARNING ******************************
1074 KERNCONF replaces the variable KERNEL for buildkernel. You
1075 should update your scripts and make.conf accordingly.
1078 config has changed to allow DEV_FOO as a replacement for NFOO.
1079 This requires a new config to build correctly.
1082 The kernel option I386_CPU is now mutually exclusive with the
1083 other cpu types. If you have an i386 system, be sure that it
1084 only had this line. Remove it for all other configurations.
1087 Changes to the kernel require it and burncd be in sync.
1090 Everyone who has hw.sndunit set to something in
1091 /etc/sysctl.conf, it is now hw.snd.unit.
1094 ex and vi were broken by some changes to sys/queue.h. If you
1095 have a bad vi, you will see make buildworld fail with a core
1096 dump while building termcap. You can work around this problem
1097 by adding -k to your make buildworld. This will cause the
1098 build to complete and install a new vi. Once that's done, you
1099 can rebuild again without the -k to pick up anything that
1100 might have been ignored by the -k option.
1102 Others have suggested that you can just rebuild libc if your
1103 vi/ex is dynamically linked, but I've not received any reports
1107 There have been some changes to libcrypt in -current. The
1108 libscrypt/libdescrypt symlink silliness is gone and the installed
1109 libcrypt is fully functional. Be aware of this.
1112 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1113 now require the addition of flag 0x80000 to their config line
1114 in pccard.conf(5). This flag is not optional. These Linksys
1115 cards will not be recognized without it.
1118 Important new FreeBSD-version stuff: PAM support has been worked
1119 in, partially from the "Unix" OpenSSH version. This requires
1120 adding the following in pam.conf:
1122 sshd auth sufficient pam_skey.so
1123 sshd auth required pam_unix.so try_first_pass
1124 sshd session required pam_permit.so
1127 cvs updated to 1.11.
1130 The random device needs more entropy, so you need to make sure
1131 that you've run mergemaster to get a /etc/rc which will seed
1132 /dev/random. If you don't and the system hangs after ldconfig,
1133 then banging on the keyboard randomly until it unhangs is one

1154 The ports tree's new layout is in place. Be sure to update
1155 your entire ports tree, or you will have problems.
1158 The perl build procedure no longer installs miniperl, nor uses
1159 the installed miniperl. It is recommended that you delete
1163 This weekend the ports tree will be updated to a new layout.
1164 It will be in an inconsistent state until noted in the UPDATING
1165 file, or with asami-san's message to the relevant mailing
1166 lists. With this new layout, you'll need to update the whole
1167 tree for anything to work.
1170 There was a change in the passwd format. Need more information.
1173 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1174 place. Please update boot loader (not the boot blocks) at the
1175 same time as your kernel.
1178 The new pmtimer device is necessary for laptops. Failure to
1179 include the device will cause suspended laptops losing time
1180 when they resume. Include
1182 in your config file and
1183 hint.pmtimer.0.at="isa"
1184 to your /boot/device.hints file.
1187 The random device has been turned into a (pseudo-)device,
1188 rather than an option. The supplied kernel config files have
1189 been updated. You will need to do something similar in your
1190 own kernel config file.
1195 If you prefer to load the loadable module, you need to do
1199 The random device module has been renamed from randomdev.ko to
1200 random.ko. You will need to edit your /boot/loader.conf to
1201 reflect this if you load this module at boot time.
1202 The line should read:
1206 The SMPNG commit has happened. It should work, but if it
1207 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1208 to be a variety of minor issues. Please see 20000905 to make
1209 sure you don't have model loading problems which might at
1210 first blush appear related to SMP.
1213 nsswitch has been imported from NetBSD. Among other things,
1214 this means that /etc/host.conf is no longer used. See
1215 nsswitch.conf(5) instead. Note that at boot time rc.network
1216 will attempt to produce a new nsswitch.conf file for you if you
1217 don't have one, and you have host.conf.
1220 The ucred structure changed size. This breaks the interface
1221 that mountd uses. Trying to use an older mountd with a newer
1222 kernel guarantees a panic. This means that you need to use
1223 kernels newer than today only with matching mountd, but you
1224 needed to do that anyway with the boot loader changes.
1227 The boot loader has been updated. The new default kernel is
1228 now /boot/kernel/kernel.ko. The new default module location
1231 You *MUST* upgrade your boot loader and kernel at the same time.
1232 The easiest way to do this is to do the buildworld/buildkernel/
1233 installkernel/installworld dance.
1235 Furthermore, you are urged to delete your old /modules directory
1236 before booting the new kernel, since kldload will find stale
1237 modules in that directory instead of finding them in the correct
1238 path, /boot/kernel. The most common complaint that this cures
1239 is that the linux module crashes your machine after the update.
1241 if [ ! -d /boot/kernel.old ]; then
1242 mv /modules.old /boot/kernel.old
1243 chflags noschg /kernel.old
1244 mv /kernel.old /boot/kernel.old/kernel.ko
1245 chflags schg /boot/kernel.old/kernel.ko
1249 A new issue with the sendmail upgrade has come to light.
1250 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1251 incorrectly install the default aliases in /etc/mail rather than
1252 move the old one from /etc. So you'll need to manually move the
1253 file, create a symbolic link, remove the old /etc/aliases.db and
1254 run newaliases. For safety sake, you should stop sendmail
1255 while doing this and run the upgrade when locally sourced email
1256 is not likely to be generated.
1259 /boot/device.hints is now required for installkernel to
1260 succeed. You should copy GENERIC.hints for your architecture
1261 into /boot/device.hints. If and only if you compile hints
1262 into your kernel, then this file may be empty. Please note,
1263 if you have an empty or missing /boot/device.hints file and
1264 you neglected to compile hints into your kernel, no boot
1265 messages will appear after the boot loader tries to start the

1277 to /etc/make.conf. If you forget to do this,
1278 chmod 4511 /usr/bin/suidperl
1279 will fix this until the next build.
1282 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1283 visible changes that may immediately affect your configuration
1285 - New default file locations from src/contrib/sendmail/cf/README
1286 - newaliases limited to root and trusted users
1287 - MSA port (587) turned on by default
1288 - New queue file naming system so can't go from 8.11 -> 8.9
1289 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1290 - FEATURE(`nullclient') is more full featured
1291 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1292 - mail.local FreeBSD-only -b option changed to -B
1293 - See src/contrib/sendmail/RELEASE_NOTES for more info
1296 suidperl (aka sperl) is no longer build by default. You must
1297 specifically define BUILD_SUIDPERL to "true" for it to be build.
1298 Furthermore, we recommend that you remove /usr/bin/sperl* and
1299 /usr/bin/suidperl files from your system unless you have a
1300 specific use for it.
1303 Networking defaults have been tightened. Anybody upgrading
1304 /etc/defaults/rc.conf needs to add the following lines to
1305 /etc/rc.conf if they want to have the same setup
1306 afterwards (unless the variables already are set, of course):
1307 # Enable network daemons for user convenience.
1309 portmap_enable="YES"
1310 sendmail_enable="YES"
1313 If you have null_load="YES" in your /boot/loader.conf, you
1314 will need to change that to nullfs_load="YES".
1317 The "installkernel" target has changed slightly. Now even if
1318 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1319 it will install the MYKERNEL file (built with the buildkernel
1320 target) as /kernel rather than /MYKERNEL. Those who have
1321 updated their /boot/loader.conf files to point to /MYKERNEL
1322 should remove that entry or perform manual rename of /kernel
1326 If you use CVSUP or CTM to get CVS trees, AND you used to get
1327 the old crypto files from internat.freebsd.org AND you check
1328 out files from the CVS tree with the cvs command, please read
1329 http://people.freebsd.org/~imp/internat.txt
1330 for details on potential problems that you might have and how
1333 If you are merely a mirror, or don't answer yes to each of the
1334 clauses above, you needn't worry.
1337 /etc/security has been updated to print the inode number of
1338 setuid programs that have changed. You will see a large spike
1339 in the number of changed programs the first time when you run
1340 mergemaster to get a new /etc/security.
1343 /dev/random now has good entropy collection (from the keyboard
1344 and sysmouse drivers). Please ensure that either `options
1345 RANDOMDEV' is present in your kernel config file or that
1346 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1347 not have the /dev/random driver, OpenSSL (and consequently
1348 lots of crypto tools (like SSH)) will fail with strange
1349 errors. (see below, 20000624).
1351 FreeBSD-current is safe again to run Crypto.
1354 phk made the malloc default options AJ. This may slow things
1355 down and uncover other latent bugs in the code. If you need to
1356 run at full speed, you can disable this by doing the following:
1357 ln -s aj /etc/malloc.conf
1360 libftpio's version was accidentally bumped a few days ago. This
1361 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1362 before doing your next buildworld/installworld pair. It certainly
1363 won't hurt to remove it before the update procedure. It will
1364 break fetch until a new one is built, but ftp can be used in the
1368 The crypto packages have changed for the cvsup. This has been done
1369 in a backward compatible way, but the old packages will go away at
1370 some point in the future. Look at /usr/share/examples/cvsup for
1374 With the new sys/modules/sound/drivers/*, you will need to
1375 set SYSDIR until you do an installworld after July 7th.
1378 rc.shutdown and rc will now call the rc.d scripts with start
1379 or stop. This may cause some harmless warnings from older
1380 rc.d scripts that haven't been updated.
1383 The libfetch based version of fetch has gone into the tree.
1384 Minor problems may result on some of the less popular sites,
1385 which should be reported to des@freebsd.org.
1388 From approximately this date forward, one must have the crypto
1389 system installed in order to build the system and kernel.
1390 While not technically strictly true, one should treat it as
1391 required and grab the crypto bits. If you are grabbing CVS
1392 trees, src-all and cvs-crypto should be treated as if they
1393 were required. You should check with the latest collections
1394 to make sure that these haven't changed.
1397 Mark Murray just committed the first parts of a cleanup of
1398 /dev/zero, et al. This is also cleaning up /dev/random.
1399 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1400 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1401 until Mark can merge in the fixes to this work in progress.
1402 openssh and openssl should not be used to generate keys from this
1403 date to the completion of the work.
1405 If you must operate at this reduced level of security, add '
1406 options RANDOMDEV' to your kernel or modload the randomdev
1407 module. You may also need to copy a new MAKEDEV to /dev and
1408 recreate the random and urandom devices.
1411 The license on the softupdates is now a standard 2 clause
1412 BSD license. You may need to remove your symbolic links
1413 that used to be required when updating.
1416 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1417 the config file update procedure.
1418 http://people.freebsd.org/~imp/config-upd.html
1419 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1420 isn't buildable. However, you can generate a LINT file:
1421 cd /sys/<ARCH>/conf && make LINT
1424 Binutils 2.10 have hit the tree, or will shortly. As soon
1425 as they do, the problem noted in 20000522 will be resolved and
1426 that workaround will no longer be required.
1429 phk removed the compatibility creation of wd devices in the
1430 ad driver. If you haven't done so already, you must update
1431 your fstab, etc to use the ad devices instead of the wd
1434 In addition, you'll need to update your boot blocks to a
1435 more modern version, if you haven't already done so. Modern
1436 here means 4.0 release or newer (although older releases
1440 Peter took an axe to config(8). Be sure that you read his mail
1441 on the topic before even thinking about updating. You will
1442 need to create a /boot/device.hints or add a hints directive
1443 to your config file to compile them in statically. The format
1444 of the config file has changed as well. Please see GENERIC or
1445 NEWCARD for examples of the new format.
1447 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1448 says that it has been fixed, assume that must use the hints mechanism
1449 in the loader if you need to use a machine with very old ISA cards
1453 A new set of binutils went into the tree today. Anybody
1454 building a kernel after this point is advised that they need
1455 to rebuild their binutils (or better yet do a
1456 buildworld/installworld) before building a new kernel.
1458 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1459 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1460 is recommended that you don't set this option until the problem
1464 The ethernet drivers were all updated to clean up the BPF handling.
1467 The problems with boot blocks on the alphas have been corrected.
1468 This will require some care in updating alphas. A new libstand
1469 is requires for the boot blocks to build properly.
1472 Recompile all kld modules. Proper version dependency info
1476 Modules have been disconnected from the buildworld tree and
1477 connected to the kernel building instead.
1480 You may need to build gperf
1481 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1482 when upgrading from 4.0 -> current. The build system now uses
1483 an option only in -current.
1486 The method that we brand ELF binaries has changed to be more
1487 acceptable to the binutils maintainers. You will need to
1488 rebrand your ELF binaries that aren't native. One problem
1489 binary is the Linux ldconfig. After your make world, but
1490 before you reboot, you'll need to issue:
1491 brandelf -t Linux /compat/linux/sbin/ldconfig
1492 if you have Linux compatibility enabled on your machine.
1495 If you have really bad/marginal IDE drives, you may find they
1496 don't work well. Use pio mode instead. The easiest way to
1497 cope if you have a problem combination is to add:
1498 /sbin/sysctl hw.ata.ata_dma=0
1499 to the start of /etc/rc.conf.
1502 The ISA and PCI compatibility shims have been connected to the
1503 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1504 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1505 include the appropriate option in your kernel config. Drivers
1506 using the shims should be updated or they won't ship with
1507 5.0-RELEASE, targeted for 2001.
1510 We've entered the traditional post release dumping party.
1511 Large kernel changes are being committed and are in the
1512 works. It is important to keep the systems' klds and kernel
1513 in sync as kernel interfaces and structures are changing.
1514 Before reporting kernel panics, make sure that all modules
1515 that you are loading are up to date.
1518 If you are upgrading from an older version of FreeBSD, you
1519 need to update your boot blocks as well. 'disklabel -B ad0'
1520 will do the trick. This isn't critical until you remove your
1521 wd device entries in /dev, at which point your system will not
1525 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1526 to upgrade to 4.0 from 3.x.
1532 Avoid using make -j when upgrading. From time to time in the
1533 past there have been problems using -j with buildworld and/or
1534 installworld. This is especially true when upgrading between
1535 "distant" versions (eg one that cross a major release boundary
1536 or several minor releases, or when several months have passed
1537 on the -current branch).
1539 Sometimes, obscure build problems are the result of environment
1540 poisoning. This can happen because the make utility reads its
1541 environment when searching for values for global variables.
1542 To run your build attempts in an "environmental clean room",
1543 prefix all make commands with 'env -i '. See the env(1) manual
1544 page for more details.
1548 If you are updating from a prior version of FreeBSD (even one just
1549 a few days old), you should follow this procedure. With a
1550 /usr/obj tree with a fresh buildworld,
1551 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1552 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1554 To just build a kernel when you know that it won't mess you up
1555 --------------------------------------------------------------
1556 This assumes you are already running a 5.X system. Replace
1557 ${arch} with the architecture of your machine (e.g. "i386",
1558 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1560 cd src/sys/${arch}/conf
1561 config KERNEL_NAME_HERE
1562 cd ../compile/KERNEL_NAME_HERE
1567 If this fails, go to the "To build a kernel" section.
1569 To rebuild everything and install it on the current system.
1570 -----------------------------------------------------------
1571 # Note: sometimes if you are running current you gotta do more than
1572 # is listed here if you are upgrading from a really old current.

1578 make installkernel KERNCONF=YOUR_KERNEL_HERE
1580 <reboot in single user> [3]
1581 /etc/rc.d/preseedrandom [10]
1588 To cross-install current onto a separate partition
1589 --------------------------------------------------
1590 # In this approach we use a separate partition to hold
1591 # current's root, 'usr', and 'var' directories. A partition
1592 # holding "/", "/usr" and "/var" should be about 2GB in

1602 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \
1603 ${CURRENT_ROOT}/boot/device.hints # as needed
1604 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1605 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1606 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
1607 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1608 <reboot into current>
1609 <do a "native" rebuild/install as described in the previous section>
1610 <maybe install compatibility libraries from /usr/src/lib/compat>
1614 To upgrade in-place from 4.x-stable to current
1615 ----------------------------------------------
1616 # 5.x uses more space than 4.x. Also, the location of kernel
1617 # modules has changed. If you are installing 5.0 onto a 4.x
1618 # system, you'll need about 30MB of free disk space on your /
1619 # partition. If you have less than this, you may encounter difficult
1620 # to back out of problems with this procedure. If /tmp is on
1621 # the / partition, you may want to completely remove all its content
1622 # before upgrading, as this can be a common source of shortage of
1625 <make sure you have good level 0 dumps>
1626 <maybe fix /etc/fstab> [7]
1628 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
1629 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
1630 make installkernel KERNCONF=YOUR_KERNEL_HERE
1631 cd sys/boot ; make STRIP="" install [6]
1633 <reboot in single user> [3]

1636 rm -rf /usr/include/g++
1641 Make sure that you've read the UPDATING file to understand the
1642 tweaks to various things you need. At this point in the life
1643 cycle of current, things change often and you are on your own
1644 to cope. The defaults can also change, so please read ALL of
1645 the UPDATING entries.
1647 Also, if you are tracking -current, you must be subscribed to
1648 freebsd-current@freebsd.org. Make sure that before you update
1649 your sources that you have read and understood all the recent
1650 messages there. If in doubt, please track -stable which has
1651 much fewer pitfalls.
1653 [1] If you have third party modules, such as vmware, you
1654 should disable them at this point so they don't crash your
1657 [2] If you have legacy ISA devices, you may need to create
1658 your own device.hints to reflect your unique hardware
1661 [3] From the bootblocks, boot -s, and then do
1666 adjkerntz -i # if CMOS is wall time
1667 Also, when doing a major release upgrade, it is required that
1668 you boot into single user mode to do the installworld.
1669 For the 4.x -> 5.0 upgrade, you will also see many messages about
1670 needing to recompile your userland. These are harmless and can
1671 be ignored while you proceed to the next step.
1673 [4] Note: This step is non-optional. Failure to do this step
1674 can result in a significant reduction in the functionality of the
1675 system. Attempting to do it by hand is not recommended and those
1676 that pursue this avenue should read this file carefully, as well
1677 as the archives of freebsd-current and freebsd-hackers mailing lists
1678 for potential gotchas.
1680 [5] Usually this step is a noop. However, from time to time
1681 you may need to do this if you get unknown user in the following
1682 step. It never hurts to do it all the time. You may need to
1683 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1684 install) after the buildworld before this step if you last updated
1685 from current before 20020224 or from -stable before 20020408.
1687 [6] 4.x boot loader can be used to boot a 5.x system, however
1688 it is difficult to do that at best. If you wish to try, then
1689 you should interrupt the boot and at the ok prompt type:
1691 ok boot /boot/kernel/kernel
1692 If this fails to work, you must install a new boot loader as
1695 [7] Before you upgrade, please make sure that you are not using
1696 compatibility slices. These are device names of the form, on i386
1697 and other architectures that use MBR slicing, /dev/ad0a without the
1698 actual slice name. Chances are excellent that these will break.
1699 You generally must update these entries to use the post FreeBSD
1700 2.x form of /dev/ad0s1a.
1702 [8] In order to have a kernel that can run the 4.x binaries
1703 needed to do an installworld, you must include the COMPAT_FREEBSD4
1704 option in your kernel. Failure to do so may leave you with a system
1705 that is hard to boot to recover.
1707 [9] When checking out sources, you must include the -P flag to have
1708 cvs prune empty directories. Also, if CPUTYPE is defined in your
1709 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1710 operator, so that buildworld can override the CPUTYPE if it needs to.
1711 In case you would like to avoid installing new packages of everything,
1712 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1713 compatibility libraries are build which should allow you to continue
1714 using your existing software for a while.
1716 [10] In order to create temporary files, /dev/random must be
1717 initialized by feeding data into it. /etc/rc.d/preseedrandom
1721 This file contains a list, in reverse chronological order, of major
1722 breakages in tracking -current. Not all things will be listed here,
1723 and it only starts on March 15, 2000. Updating files can found in
1724 previous releases if your system is older than this.
