5 done items, please see the COMMON ITEMS: section later in the file.
7 NOTE TO PEOPLE WHO THINK THAT FreeBSD 5.x IS SLOW:
8 FreeBSD 5.x has many debugging features turned on, in
9 both the kernel and userland. These features attempt to detect
10 incorrect use of system primitives, and encourage loud failure
11 through extra sanity checking and fail stop semantics. They
12 also substantially impact system performance. If you want to
13 do performance measurement, benchmarking, and optimization,
14 you'll want to turn them off. This includes various WITNESS-
15 related kernel options, INVARIANTS, malloc debugging flags
16 in userland, and various verbose features in the kernel. Many
17 developers choose to disable these features on build machines
18 to maximize performance.
21 The sound device drivers are renamed. `sound' is always required,
22 while `snd_*' should be configured accordingly to your hardware.
23 Refer to NOTES for the detail of the drivers.
26 __FreeBSD_version bumped to 502122.
29 The console initialization on Alpha has been reworked and is now
30 identical to other platforms. This means that the hardcoding of
31 the serial console and the debug port has been removed. As such,
32 hints are now required for the sio(4) driver to become a console
33 or debug port. The NO_SIO option has been decommissioned because
37 A revamp of the debugging code in the kernel with some visible
38 changes beyond just the debugging experience:
39 o The DDB option is now specific to the DDB debugger backend
40 and should not be used any more for conditional compilation
41 of debugging code for when debugging is enabled. Use the KDB
43 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
44 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
45 respectively. This is in line with the first bullet.
46 o The remote GDB support has been untangled from DDB and needs
47 to be enabled seperately now. Use the GDB option for this.
48 o The GDB_REMOTE_CHAT option has been removed. Support for this
49 homegrown feature is discontinued. The GDB remote protocol
50 supports console output and it makes sense to use that.
51 o The DDB_NOKLDSYM option has been removed. The DDB debugger
52 now supports both direct symbol table lookups as well as KLD
53 symbol lookups through the linker.
56 Bluetooth code has been marked as non-i386 specific.
57 __FreeBSD_version has been bumped to 502121 to mark this change.
60 The native preemption has been added to the kernel scheduler.
61 There is some report that ULE scheduler was broken in some
62 machines and we encourage users using ULE scheduler either
63 stick with an known good kernel, or temporary switch to 4BSD
64 scheduler as a workaround.
67 The netgraph ABI version number has been incremented to indicate
68 an incompatible change in the ABI. Old netgraph nodes will refuse
69 to attach until recompiled. Netgraph now uses mbuf tags to move
70 metadata and this commit removes its home-grown metadata facility.
71 Nodes should just recompile, unless they use metadata, in which
72 case the changes are simple; the file ng_ksocket.c serves as an
73 example of such changes.
75 This also broke i4b, although the compile problem has been papered
79 ACPI has been updated to disable known-bad BIOS revisions. A message
80 will be printed on console indicating that ACPI has been disabled
81 automatically and that the user should use a newer BIOS, if possible.
82 If you think ACPI does work on your system and want to override
83 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
87 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is priviledge
88 separated now. It uses the newly created "_pflogd" user/group
89 combination. If you plan to use pflogd(8) make sure to run
90 mergemaster -p or install the "_pflogd" user and group manually.
93 Network interface cloning has been overhauled. This change will
94 require a recompile of modules using cloning and modification of
95 external ones to the new API. __FreeBSD_version has been bumped
96 to 502119 to mark this change. Additionally, users creating
97 stf(4) interfaces via "ifconfig stf" will need to update their
98 scripts as this will create an interface named "stf" instead of
99 "stf0" and ifconfig will not print "stf0" to stdout.
102 On 20040524, the /etc/rc.d/nsswitch script was modified to
103 automatically create /etc/nsswitch.conf on startup if it did
104 not already exist. Unfortunately, an error in the man page
105 was carried over to the script, resulting in incorrect
106 nsswitch settings. The simplest remedy is to remove both
107 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
108 during the next reboot.
111 The return value of sema_timedwait(9) has been changed to
112 make it consistent with cv_timedwait(9). Be sure to recompile
113 the ips module and any third-party modules which call
117 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
118 Make sure to recompile modules and any userland that makes use of
119 sizeof(struct ifnet). In order to get the altq headers in place
120 please recompile and reinstall world.
123 Splitting kern_thread.c into 2 files (adding kern_kse.c)
124 requires that you re-run config after updating your tree.
127 The MIDI drivers have been removed. Until the new module-friendly
128 ones are merged, remove or comment out midi and seq from your
129 kernel configuration.
132 Due to a new option in ipfw (versrcreach) the ipfw(8) command
133 needs to be recompiled. Normal accept/reject rules without
134 options are not affected but those with options may break until
135 ipfw(8) is recompiled.
138 Due to changes in the callout ABI, kernels compiled after this
139 date may be incompatible with kernel modules compiled prior to
143 The PCI bus power state stuff has been turned on. If this causes
144 problems for your system, please disable it using the tunable
145 hw.pci.do_powerstate=0.
148 The bulk of the pci problems have been fixed, although the floppy
149 drive is still broken.
152 A substantial update to the pci bus resource and power management
153 have been committed. Expect a bumpy ride for a few days until
154 the unanticipated problems have been resolved.
157 Due to changes in the the Yarrow initialization process,
158 /dev/random needs to be fed before operations requiring
159 temp files can succeed in single user mode. This includes
160 running "make installworld". /dev/random may be fed by running
161 "/etc/rc.d/initrandom start" or with 20040415 source by running
162 "/etc/rc.d/preseedrandom".
165 The debug.mpsafenet tunable controls whether the kernel Giant
166 lock is held across the lower levels of the network stack, and
167 by default is turned off. In the few days following 20040322,
168 the behavior of debug.mpsafenet will change such that this
169 tunable controls Giant over all levels of the network stack.
170 If you are currently setting debug.mpsafenet to 1, you should
171 set it back to 0 (the default) again during the change-over.
172 An additional note will be added to UPDATING when sufficient
173 locking is merged to permit this to take place.
176 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
177 64-bits. This is a very major incompatible change, so people
178 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
179 detailed instructions on how to make this upgrade. People
180 upgrading FreeBSD on other platforms can ignore this event.
183 The packet filter (pf) is now installed with the base system. Make
184 sure to run mergemaster -p before installworld to create required
185 user account ("proxy"). If you do not want to build pf with your
186 system you can use the NO_PF knob in make.conf.
187 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
188 pf system consists of the following three devices:
190 device pflog # optional
191 device pfsync # optional
194 If you are having trouble with the libc_r -> libpthread transition
195 (see the 20040130 entry), place the following lines at the top of
198 libc_r.so.5 libpthread.so.1
199 libc_r.so libpthread.so
201 This will cause all programs and libraries linked against libc_r
202 to use libpthread instead.
205 Some sshd configuration defaults have changed: protocol version 1
206 is no longer enabled by default, and password authentication is
207 disabled by default if PAM is enabled (which it is by default).
208 OpenSSH clients should not be affected by this; other clients may
209 have to be reconfigured, upgraded or replaced.
212 The ABIs defined in <resolv.h> and <netdb.h> have been updated
213 to support improved reentrancy. Multi-threaded programs that
214 reference the "_res" or "h_errno" symbols may experience some
215 problems if they are not recompiled. Single-threaded programs
216 should remain unaffected.
219 routed has been updated in the base system from the vendor
220 sources, routed v2.27, from rhyolite.com. This change means that
221 for users who use RIP's MD5 authentication feature, FreeBSD
222 -CURRENT's routed is now incompatible with previous versions
223 of FreeBSD; however it is now compatible with implementations
224 from Sun, Cisco and other vendors.
227 The tcpcb structure has changed and makes a recompile of libkvm
228 and related userland network utilities neccessary.
231 The cdevsw structure has changed in two externally visible ways.
232 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
233 Second, the d_version field must be filled in with D_VERSION.
234 Drivers outside the tree will need to be updated.
237 The /etc/rc.d/ttys script has been removed. It is no longer
238 necessary since devfs has been mandatory for some time.
241 libkse has been renamed back to libpthread and is now the
242 default threads library. The gcc -pthread option has also
243 been changed to link to libpthread instead of libc_r. For
244 alpha and sparc64 machines, libkse is not renamed and links
245 are installed so that libpthread points to libc_r. Until
246 the ports system is updated to handle this change, it is
247 recommended that folks install an /etc/libmap.conf(5) that
248 maps libc_r to libpthread. If you have any binaries or
249 libraries linked to libkse, then it is also recommended
250 that you map libkse to libpthread. Anyone that is using
251 nvidia supplied drivers and libraries should use a libmap.conf
252 that maps libpthread to libc_r since their drivers/libraries
253 do not work with libpthread.
256 ULE has entered into its probationary period as the default scheduler
257 in GENERIC. For the average user, interactivity is reported to be
258 better in many cases. On SMP machines ULE will be able to make more
259 efficient use of the available parallel resources. If you are not
260 running it now, please switch over, replacing the kernel option
261 SCHED_4BSD with SCHED_ULE.
264 Move LongRun support out of identcpu.c, where it hardly
265 belongs, into its own file and make it opt-in, not mandatory,
266 depending on CPU_ENABLE_LONGRUN config(8) option.
269 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
270 if the login process is unable to successfully set the
271 process credentials to include all groups defined for the
272 user. The current kernel limit is 16 groups; administrators
273 may wish to check that users do not have over 16 groups
274 defined, or they will be unable to log in.
277 The ACPI module has been reactivated. It is no longer required
278 to compile ACPI support into kernels statically.
281 The statfs structure has been updated with 64-bit fields to
282 allow accurate reporting of multi-terabyte filesystem
283 sizes. You should build world, then build and boot the new kernel
284 BEFORE doing a `installworld' as the new kernel will know about
285 binaries using the old statfs structure, but an old kernel will
286 not know about the new system calls that support the new statfs
288 Note that the backwards compatibility is only present when the
289 kernel is configured with the COMPAT_FREEBSD4 option. Since
290 even /bin/sh will not run with a new kernel without said option
291 you're pretty much dead in the water without it. Make sure you
292 have COMPAT_FREEBSD4!
293 Running an old kernel after a `make world' will cause programs
294 such as `df' that do a statfs system call to fail with a bad
295 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
296 that cfsd (ports/security/cfs) needs to be recompiled after
297 these changes are installed.
299 ****************************DANGER*******************************
301 DO NOT make installworld after the buildworld w/o building and
302 installing a new kernel FIRST. You will be unable to build a
303 new kernel otherwise on a system with new binaries and an old
307 Some netgraph string length constants have been changed. This
308 change requires the netgraph kernel modules and all netgraph
309 userland components to be in sync. Especially users who require
310 netgraph to boot need to make sure to have world and kernel in
311 sync before rebooting.
314 Hyperthreading logical CPU's are no longer probed by default
315 when using the MP Table. If ACPI is being used, then logical
316 CPUs will be probed if hyperthreading is enabled in the BIOS.
317 If ACPI is not being used and hyperthreading is enabled in the
318 BIOS, logical CPUs can be enabled by building a custom kernel
319 with the option MPTABLE_FORCE_HTT enabled.
322 The i386 APIC_IO kernel option has been replaced by
323 'device apic'. The ACPI module has also been temporarily
324 disabled, so ACPI must be statically compiled into your
325 kernel using 'device acpi' if you wish to use the ACPI driver.
328 The API and ABI of struct ifnet have been changed by removing
329 the if_name and if_unit members and replacing them with
330 if_xname, if_dname, and if_dunit. All network drivers and most
331 userland programs which include net/if_var.h must be updated
332 and recompiled. __FreeBSD_version has been bumped to 501113 to
336 Changes to the cdevsw default functions have been made to remove
337 the need to specify nullopen() and nullclose() explicitly.
338 __FreeBSD_version bumpted to 501110.
341 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
342 mount_cd9660(8) need to be in sync with kernel.
345 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
346 also be explicitly configured. Previously this dependency was
347 magically handled through some cruft in net/pfil.h; but that has
348 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
349 will fail with obtuse errors in ip_fil.c.
352 Fix a bug in arplookup(), whereby a hostile party on a locally
353 attached network could exhaust kernel memory, and cause a system
354 panic, by sending a flood of spoofed ARP requests. See
355 FreeBSD-SA-03:14.arp.
358 A change to /etc/defaults/rc.conf now causes inetd to be started
359 with `-C 60' if it is not overridden in /etc/rc.conf. This
360 causes inetd to stop accepting connections from an IP address
361 that exceeds the rate of 60 connections per minute.
364 The following rc.d scripts have been removed and should be
365 deleted from your installation: atm2.sh atm3.sh devdb
366 localdaemons network1 network2 network3. Depending on when
367 you last updated world and used mergemaster(8) you may or
368 may not have problems during the rc boot sequence. The simplest
369 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
370 The atm2.sh atm3.sh and devdb scripts were removed some time
371 ago, so depending on when you installed -CURRENT these scripts
372 may or may not exist on your system.
375 ATAng has been committed. You need to build world as sys/ata.h
376 has changed, and userland atacontrol depends on it.
377 If you use ATA SW raids you need "device ataraid" in your
378 kernel config file, as it is no longer pulled in automatically.
381 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
382 Among other things, this changes the device enumeration to be
383 closer to Solaris. Be aware that, this can even cause the machine
384 to not boot without manual intervention before the fstab is adjusted.
387 All current USB and Firewire quirks in da(4) have been deprecated
388 and will be removed for 5.2. If this causes failure for your
389 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
390 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
391 so the quirk can be re-enabled.
394 Problems with entry 20030714 have been corrected and no known issues
395 with /rescue and -j exist for host systems after this point in time.
398 FPU-less support has been removed from FreeBSD. Chances are you won't
399 notice. 386+387 support should still work after this change, but
400 it is now a minimum requirement for the i386 port that you have real
404 Some people are having problems with changes related to /rescue.
405 If you are building -j N, you will need to define NO_RESCUE. Others
406 will need to define it if /rescue has issues with their environment.
407 People should report those issues to current@.
410 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
411 across this point. Further, it might be a good idea to remove
415 Remove deprecated locale names and transition period code
416 for them, finishing switching to the new scheme. Check your
417 LANG environment variable.
420 CCD has been changed to be a fully GEOMified class. Kernel
421 and ccdconfig(8) needs to be in sync, this is particularly
422 important to remember beforehand if your source tree is on
423 a ccd device. Consider making a copy of the old ccdconfig
424 into /boot/kernel.good or wherever you keep your backup
428 There was a small window in which sed(1) was broken. If you
429 happen to have sed(1) installed during that window, which is
430 evidenced by an inability to build world with the failure
431 given below, you need to manually build and install sed(1)
432 (and only sed(1)) before doing anything else. This is a one-
433 time snafu. Typical failure mode:
435 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
436 targmatch.h:7:1: null character(s) ignored
437 targmatch.h:12:1: null character(s) ignored
438 targmatch.h:16:1: null character(s) ignored
441 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
442 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
443 usr.bin/sed/process.c).
446 Kerberos 5 (Heimdal) is now built by default. Setting
447 MAKE_KERBEROS5 no longer has any effect. If you do NOT
448 want the "base" Kerberos 5, you need to set NO_KERBEROS.
451 groff has been updated. If you try to do a buildworld and
452 get an infinite loop in troff, update to May 4th or newer. If you
453 have a newer kernel than userland, you may need to set the OSRELDATE
454 to 500110 in your environment before starting a buildworld.
457 The old rc system has been removed. Please report any problems
458 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
459 Your personal versions of these files will not be removed, so you can
460 continue to use them. However, you should take great care when updating,
461 especially when using mergemaster, since the compatibility code that
462 utilizes these old scripts has also been removed.
465 A bug has been fixed in /dev/devctl which would cause devd
466 to hang on boot, were it not for a workaround in devd. The
467 work around in devd will be removed around 20030507. You
468 have until then to upgrade your kernel before updating
469 userland. In general, you should have a userland and
470 kernel that's in sync with each other. However, given the
471 effects of this bug (hang on boot when starting devd), some
475 Alphas with libc from between 20030312 and 20030329 exhibit
476 floating point exceptions (FPEs), most notably in awk(1)
477 while upgrading the system through a buildworld.
479 So, to successfully upgrade your Alpha, you must either
480 downgrade your libc.so to a pre-20030312 version, or update
481 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
482 to CFLAGS, then forcibly rebuild and install libc:
484 cd /usr/src/lib/libc && \
485 make cleandir && make obj && \
486 make -DNOMAN -DNOPROFILE all && \
487 make -DNOMAN -DNOPROFILE install
490 sendmail 8.12.7 has been imported. It has one important
491 change for IPv6 users. The default submit.mc now uses
492 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
493 used to connect to the MTA. Users on IPv6-only machines
494 will need to edit /etc/mail/submit.mc appropriately.
497 NODEVFS option has been removed and DEVFS thereby made standard.
498 This makes all references to MAKEDEV obsolete, and they should
499 be removed when convenient.
502 The name of the device for the ofw console has changed, sparc64 users
503 must run mergemaster to update their installed /etc/ttys.
506 The scheduler framework has grown a second scheduler and consequently
507 you must specify one and only one scheduler in your kernel config.
508 The cvs config files have been updated to use the old scheduler
509 which may be selected via 'options SCHED_4BSD'. If you would like
510 to try the new, much more experimental, scheduler please try
511 'options SCHED_ULE' and contribute to the arch@ discussion.
514 A new version of the wi driver has been imported into the tree.
515 One now must have device wlan in the config file for it to operate
518 In addition, there have been some changes to how wi devices are
519 configured for point to point links to bring it more in line
520 with the former way of doing things, as well as compatibility
524 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
525 used an incompatible form of ABI for returning structures and unions
526 which FreeBSD's GCC maintainers were not aware of relative to previous
527 versions of FreeBSD. We have gone back to the ABI for now, and any
528 code compiled which is required to interoperate with other code (not
529 built at the same time) returning structs or unions should be
533 A name change in /etc/netconfig has been reverted to stay
534 compatible with suns TIRPC and also with NetBSD. You need
535 to run mergemaster after make world. A new libc does still work
536 with an outdated /etc/netconfig for some time, but you'll get
537 a warning. This warning will be removed in 20030301.
540 The recent binutils upgrade marks a kernel flag day on
541 sparc64: modules built with the old binutils will not work
542 with new kernels and vice versa. Mismatches will result in
543 panics. Make sure your kernel and modules are in sync.
546 The value of IPPROTO_DIVERT has changed. Make sure to keep
547 your kernel, netstat, natd and any third-party DIVERT
551 Old, compatibility slices have been removed in GEOM kernels.
552 This means that you will have to update your /etc/fstab to
553 not use disk devices of the form /dev/ad0a. Instead, you
554 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
555 partition really is on. The old device names have gone
556 away, so if you use them anywhere else, you must also adjust
557 those uses. (This doesn't affect the disks formatted in
558 the ``dangerously-dedicated'' mode.)
561 Alphas with kernels from between 20020830 and 20021023 and/or
562 rtld (ld-elf.so.1) older than 20021023 may experience problems
563 with groff while doing a buildworld (kernel: "out of memory",
564 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
565 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
567 So, to successfully upgrade your Alpha, you must either
568 upgrade your kernel and rtld first (which might be a bit
569 tricky), or avoid running the bootstrapped groff during the
570 "transitional" buildworld. To avoid running groff during the
571 transitional upgrade run make buildworld with -DNOMAN,
572 -DNO_SHAREDOCS, and -DNO_LPR.
575 gcc has been upgraded to 3.2. It is not all binary compatible
576 with earlier versions of gcc for c++ programs. All c++
577 programs and libraries need to be recompiled.
579 Also, if you encounter g++ issues, rm /usr/include/g++/* before
580 doing an installworld to make sure that stale files are removed.
583 Our /etc/termcap now has all the entries from the XFree86 xterm
584 almost unchanged. This means xterm now supports color by default.
585 If you used TERM=xterm-color in the past you now should use
586 TERM=xterm. (xterm-color will lead to benign warnings).
589 A "bug" in gcc(1) that was hiding warning in system headers was
590 fixed. It's probably time to add -DNO_WERROR to your make line
594 COPY is being deprecated. The 20010530 change was reverted, as
595 it causes far more pain than was expected, and to always compare
596 before installing, please use INSTALL="install -C" again. The
597 -C option is now silently ignored when used with the -d option.
600 Problems with libc_r clients like KDE and GNOME have been resolved.
601 There are still some minor problems with some signals but the
602 system is stable enough for general use again. SMP is less so than UP
603 but each can successfully complete multiple buildworlds.
604 Libkvm needs to be recompiled due to KSE.
607 Now would be a bad time to upgrade. Something in or near the
608 KSE commit totally broke programs using libc_r like KDE and
612 The k5su utility installed as part of Kerberos 5 is no longer
613 installed with the set-user-ID bit set by default. Add
614 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
615 with the set-user-ID bit set.
618 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
619 Unfortunately our native GDB (at version 4.18) does not understand
620 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
621 generated debugging information for our native GDB.
624 Due to the way CVS works, it may not properly update src/contrib/gcc
625 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
626 and then do a cvs update.
629 When exec'ing set[ug]id executables, the kernel now ensures that the
630 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
633 New sendmail startup scripts have been installed to make it
634 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
635 variable sendmail_enable to "NO" no longer prevents any sendmail
636 daemons from starting. Instead, either set sendmail_enable to
637 "NONE" or change mta_start_script to a script for starting
638 an alternative MTA. Setting mta_start_script to "" will
639 also prevent any MTA from being started at boot.
642 UCONSOLE is no longer a valid kernel option.
645 FreeBSD 5.0 DP-1 was basically branched today.
648 Warnings are now errors in the kernel. Unless you are a developer,
649 you should add -DNO_WERROR to your make line.
652 sendmail 8.12.2 has been imported. The sendmail binary is no
653 longer a set-user-ID root binary and the infrastructure to support
654 command line mail submission has changed. Be sure to run
655 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
656 and /etc/mail) and read /etc/mail/README for more details.
658 Due to the import of sendmail 8.12.2, a new user and group are
659 required in order for sendmail to run as a set-group-ID
660 binary. A 'make installworld' will use the new user and group
661 to set the owner and group of /var/spool/clientmqueue and will
662 fail if the new user and group do not exist. The 'smmsp' user
663 and group must be merged from src/etc/group and
664 src/etc/master.passwd before using 'make installworld'.
665 'mergemaster -p' will do this. You may need to install
666 mergemaster before this will work if you are updating from a
667 very old version of current. The updating recipe has changed
671 The preferred configuration method for PAM is now /etc/pam.d/
672 rather than /etc/pam.conf. If you have an unmodified
673 pam.conf, just delete it after your next mergemaster run. If
674 you have local modifications, you can use
675 /usr/src/etc/pam.d/convert.pl to incorporate them into your

686 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
687 started out its life in the ISDN4BSD project as an offspring
688 from sys/net/if_spppsubr.c, which eventually got a life of its
689 own. All the accumulated features and bugfixes of the i4b
690 version have now been merged back into the base system's
691 version now. The only user-visible change resulting from this
692 is that i4b's sppp(4) interfaces are to be managed with
693 spppcontrol(8) again, since ispppcontrol(8) has been retired
694 as well. (There has never been rc file support for
695 ispppcontrol in -current, but only in -stable. That will be
696 reverted by the time the changes are MFCed.)
699 The fdc(4) driver has been updated and now automatically
700 recognizes media in `standard' formats (like 1440 KB and
701 720 KB for a 3.5" high-density drive) when accessing the
702 default device node (e. g. /dev/fd0). The old variety of
703 floppy device nodes /dev/fd*.* is no longer present by
704 default, devices can be created (in DEVFS) on demand. They
705 will need to be customized then for `odd' densities using
709 The bugs in procfs' debugging support code have been fixed,
710 and truss(1) now works again.
713 Daily security checks have been split out to use the periodic(8)
714 scripts. Some change in configuration may be necessary. Please
716 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
720 sos added VCD/SVCD support to ata driver and that needs the
721 kernel and burncd to be in sync.
724 The procfs pseudo-filesystem has now been converted to use the
725 pseudofs framework. If you have 'options PROCFS' in your
726 kernel config, you'll need to add 'options PSEUDOFS' if it's
729 This change temporarily breaks truss(1); use ktrace(1) instead
730 until the issue has been resolved.
733 A security hole in OpenSSH involving `UseLogin yes' has been
737 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
738 after this date. You need to do this only once.
741 Most of the awk issues have been resolved. Some rough
742 edges may be left, but for the most part things should be
743 back to "normal." For CURRENT's usual definition of "normal."
746 Awk has been upgraded to the one true awk from bell labs. Expect
747 choppy waves in the upgrade process.
750 The asr driver problem has been resolved.
753 Due to changes in other parts of the system, the asr driver
754 now causes the system to panic on boot. Do not use it pending
755 correction. Comment it out of any kernel config file that you
756 try to use from this date forward.
759 When crossbuilding, use TARGET=xxx where you used to use
760 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
761 unless you are changing both of them. To cross build pc98 on
762 an alpha, for example, you need to set TARGET=pc98 and
766 The kernel interface that burncd depends on has changed.
767 You must recompile both the kernel and userland applications
771 When crossbuilding, please set TARGET_ARCH rather than
772 MACHINE_ARCH to indicate the target. In the future, one will
773 set TARGET_MACHINE where you set MACHINE now. At the moment,
774 setting MACHINE alone for same MACHINE_ARCH machines works
775 (eg, you can build pc98 on an i386 machine and vice versa).
778 Some weird problems result from using ACPI on some machines.
779 To disable ACPI you can add
780 hint.acpi.0.disabled="1"
781 to /boot/loader.conf (or by putting set X=Y at the boot
784 Alternatively, you can remove it from /boot/kernel/acpi.ko
785 or use the MODULES_OVERRIDE function in your kernel config
786 file and not list acpi in that list.
789 The buildworld has been fixed. You may need to install
790 the 4.x compatibility libraries for some old binaries
791 to work. Add COMPAT4X=true to your /etc/make.conf to
792 get them installed on every installworld, or execute the
793 following to get them installed only once:
794 cd src/lib/compat/compat4x.<arch>
796 You will see ``__stdoutp undefined'' until you do this.
799 There's a bug in the world build process. The cross-tools
800 are build with the NEW headers, but the OLD libc.a. This
801 leads to all kinds of problems with the new libc. A temporary
803 CFLAGS="-O -pipe -D_OLD_STDIO"
804 before building world when upgrading from 4.x to current. This
805 can be removed afterwards.
807 A proper fix to the buildworld target is needed.
810 Peter has committed his new kthread nfs client/server code.
811 NFS may be unstable after this date.
814 KSE has hit the tree. Lots of things are now different in
815 the kernel. While a few problems were introduced in the
816 initial commit, most of the major ones have been found and
820 In OLDCARD, CardBus bridges appear to be stable. The work
821 arounds described in the 20010604 entry are now no longer
822 necessary and will be ignored. Most insert/remove problems
823 have been rectified around this date.
826 named now runs as user bind and group bind rather than as
827 root. If named_enable is set to YES in /etc/rc.conf, ensure
828 that user bind is available in /etc/passwd (using vipw(8))
829 and that group bind is available in /etc/group. Also make
830 sure that user or group bind has read (and not write)
831 permission for your name server configuration and that it
832 has read and write permission for your slave zone files and
835 If you wish to continue to run named as root (a less secure
836 alternative), add a line to /etc/rc.conf saying
841 The PAM libraries have had an API upgrade that is beyond
842 the ability of the shared library major number to handle.
843 It is manifested by PAM-using ports dumping core. The
844 solution is to rebuild those ports.
847 The kernel compile module has moved from src/sys/compile/FOO
848 to src/sys/${MACHINE}/compile/FOO.
851 The pccard modem issue from 20010613 has been corrected.
852 OLDCARD support is still a little weak in -current. slot 1 is
853 known not to work on some TI based cardbus bridges. Some
854 cardbus bridges do not properly detect insert/removal events.
855 IRQ configuration needs more safety belts.
858 Softupdates problems have been corrected.
861 Peter ripped out the linkerset support. You must, as always,
862 rerun config after you cvsup if you are using the traditional
863 kernel building methods.
866 pccard modems may not work with current after 20010604 date. Some
867 do, others result in panics. *MAKE*SURE* that you update your
868 config and /etc/rc.conf ala the 20010604 entry, or you will have
869 problems (this issue will be fixed, it just hasn't been yet).
872 SOFTUPDATES seem to be broken since the middle of May or so. Do not
873 use them in current. You can disable softupdates on all mounted
874 partitions, or remove SOFTUPDATES the kernel config file.
877 After Peter's commits to the hints code, people have been noticing
878 that certain devices are attached (or try to) twice. This is due
879 to having both static hints as well as a /boot/device.hints. To
880 work around this issue, please use only one or the other mechanism
881 until this bug is fixed.
883 Please note that a feature of config is that if you have config
884 file FOO and FOO.hints, it automatically adds FOO.hints to the
885 hints.c file, whether you want it to or not.
888 Locale names have changed to match other systems better.
891 pccard support for pci cards has been committed. You must change
892 your /etc/pccard.conf irq lines. It must match the irq used by
893 pcic device. Interrupt storms may result if you fail to do this.
894 Interrupt storms look a lot like a hang.
896 You must also install a new pccardd, otherwise you will get an
897 interrupt storm at card reset time (just after it tells you what
900 pccardd_flags="-I" is necessary for the time being. It tells pccardd
901 not to ask the kernel if the interrupt is really free or not before
902 using it. You can either change the /etc/pccard.conf irq lines to
903 match pcic, or add "-i X" to the pccardd_flags.
906 INSTALL=install -C is being deprecated. If you want to do this,
907 use COPY=-C instead. The former method will be supported for only
908 a limited time. If you see
910 install: warning: the -d and -C options may not be specified together
912 in your makeworld, then you need to migrate towards using
916 It appears that vm is now stable enough to use again. However,
917 there may be other problems, so caution is still urged. alpha
918 definitely is in bad shape.
921 Minor repo damage has happened. This may cause problems
922 with cvsup of ports. If you get errors, please see
923 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
924 at the bottom for details on a workaround. The error message
926 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
929 Vm and/or swapping are busted on -current. Please be patient.
932 pccard has had much reorganizational work done to it over
933 the past few days. Everything should still work, but if
934 not, please contact imp@freebsd.org.
937 ata ioctl changed. Make sure to recompile both kernel and
938 userland at the same time.
941 New ncurses imported.
944 DEVFS is now opt out, not opt in. Barring major problems, this
945 will be the only way to go starting July 1.
948 OpenSSH has been updated to 2.9. Some defaults are different,
949 including RhostsRSAAuthentication, which changes from yes to no.
952 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
955 Building perl was broken at 02:25:25 PDT.
958 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
959 go back in the water.
962 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
963 this date, but before the correction date.
966 old fsck and new kernel interactions appear to have been fixed.
969 fsck and the kernel were changed to handle some optimizations
970 to directory layout. This breaks backward compatibility.
971 Update only if you understand that you must not use the old
972 fsck with the new kernel ever.
975 fsck has changed the meaning of the pass column in /etc/fstab.
976 Please see the cvs commit to fsck.8 or the fsck.8 man page for
977 details. It is unclear if changes to /etc/fstab are necessary.
980 portmap had changed name to rpcbind for maximum POLA in your
981 current world. /etc/hosts.{allow,deny} needs changes. nfs and
982 other rpc based programs that rely on portmapper will not work
983 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
986 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
987 and ATA_ENABLE_TAGS are no longer kernel options. They have
988 been replaced by tunables. See ata.4 for details.
991 The fxp driver was converted to use miibus. If you compile
992 fxp into your kernel statically, you will need to add miibus.
995 The wi device now defaults to BSS (infrastructure) mode
999 /dev/urandom should be a symbolic link to /dev/random now.
1000 Users of current not using DEVFS need to run MAKEDEV std.
1001 ssh might not work if you don't.
1004 The ed driver has been updated. It now allows mii attachments,
1005 which means that you must include the miibus in your kernel if
1006 you use the ed driver.
1009 The problems with libc have been corrected. It is now mostly
1010 safe to go back into the water.
1013 The size of FILE was changed. This breaks upgrading. If
1014 you must upgrade, be prepared for pain. It also breaks almost
1015 all binaries that you've compiled on -current. You are warned
1016 that before upgrading would be a good time to do a level 0
1017 dump of your system. No, really, I mean it this time.
1019 To get to the new system, you'll need to use the following
1020 workaround. Hopefully this can be sorted out so that we
1021 don't have to move this to the updating section.
1023 To get around the installworld problem, do:
1024 # cd /usr/src/usr.bin/sed
1028 If that doesn't work, then try:
1029 # make -k installworld
1033 DEVFS is now the default. If you use vinum, make sure that you
1034 do not include devfs in your kernel as problems result.
1037 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1038 Remove them from your config.
1041 ****************************** WARNING ******************************
1042 buildkernel has been changed slightly
1043 ****************************** WARNING ******************************
1044 KERNCONF replaces the variable KERNEL for buildkernel. You
1045 should update your scripts and make.conf accordingly.
1048 config has changed to allow DEV_FOO as a replacement for NFOO.
1049 This requires a new config to build correctly.
1052 The kernel option I386_CPU is now mutually exclusive with the
1053 other cpu types. If you have an i386 system, be sure that it
1054 only had this line. Remove it for all other configurations.
1057 Changes to the kernel require it and burncd be in sync.
1060 Everyone who has hw.sndunit set to something in
1061 /etc/sysctl.conf, it is now hw.snd.unit.
1064 ex and vi were broken by some changes to sys/queue.h. If you
1065 have a bad vi, you will see make buildworld fail with a core
1066 dump while building termcap. You can work around this problem
1067 by adding -k to your make buildworld. This will cause the
1068 build to complete and install a new vi. Once that's done, you
1069 can rebuild again without the -k to pick up anything that
1070 might have been ignored by the -k option.
1072 Others have suggested that you can just rebuild libc if your
1073 vi/ex is dynamically linked, but I've not received any reports
1077 There have been some changes to libcrypt in -current. The
1078 libscrypt/libdescrypt symlink silliness is gone and the installed
1079 libcrypt is fully functional. Be aware of this.
1082 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1083 now require the addition of flag 0x80000 to their config line
1084 in pccard.conf(5). This flag is not optional. These Linksys
1085 cards will not be recognized without it.
1088 Important new FreeBSD-version stuff: PAM support has been worked
1089 in, partially from the "Unix" OpenSSH version. This requires
1090 adding the following in pam.conf:
1092 sshd auth sufficient pam_skey.so
1093 sshd auth required pam_unix.so try_first_pass
1094 sshd session required pam_permit.so
1097 cvs updated to 1.11.
1100 The random device needs more entropy, so you need to make sure
1101 that you've run mergemaster to get a /etc/rc which will seed
1102 /dev/random. If you don't and the system hangs after ldconfig,
1103 then banging on the keyboard randomly until it unhangs is one

1124 The ports tree's new layout is in place. Be sure to update
1125 your entire ports tree, or you will have problems.
1128 The perl build procedure no longer installs miniperl, nor uses
1129 the installed miniperl. It is recommended that you delete
1133 This weekend the ports tree will be updated to a new layout.
1134 It will be in an inconsistent state until noted in the UPDATING
1135 file, or with asami-san's message to the relevant mailing
1136 lists. With this new layout, you'll need to update the whole
1137 tree for anything to work.
1140 There was a change in the passwd format. Need more information.
1143 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1144 place. Please update boot loader (not the boot blocks) at the
1145 same time as your kernel.
1148 The new pmtimer device is necessary for laptops. Failure to
1149 include the device will cause suspended laptops losing time
1150 when they resume. Include
1152 in your config file and
1153 hint.pmtimer.0.at="isa"
1154 to your /boot/device.hints file.
1157 The random device has been turned into a (pseudo-)device,
1158 rather than an option. The supplied kernel config files have
1159 been updated. You will need to do something similar in your
1160 own kernel config file.
1165 If you prefer to load the loadable module, you need to do
1169 The random device module has been renamed from randomdev.ko to
1170 random.ko. You will need to edit your /boot/loader.conf to
1171 reflect this if you load this module at boot time.
1172 The line should read:
1176 The SMPNG commit has happened. It should work, but if it
1177 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1178 to be a variety of minor issues. Please see 20000905 to make
1179 sure you don't have model loading problems which might at
1180 first blush appear related to SMP.
1183 nsswitch has been imported from NetBSD. Among other things,
1184 this means that /etc/host.conf is no longer used. See
1185 nsswitch.conf(5) instead. Note that at boot time rc.network
1186 will attempt to produce a new nsswitch.conf file for you if you
1187 don't have one, and you have host.conf.
1190 The ucred structure changed size. This breaks the interface
1191 that mountd uses. Trying to use an older mountd with a newer
1192 kernel guarantees a panic. This means that you need to use
1193 kernels newer than today only with matching mountd, but you
1194 needed to do that anyway with the boot loader changes.
1197 The boot loader has been updated. The new default kernel is
1198 now /boot/kernel/kernel.ko. The new default module location
1201 You *MUST* upgrade your boot loader and kernel at the same time.
1202 The easiest way to do this is to do the buildworld/buildkernel/
1203 installkernel/installworld dance.
1205 Furthermore, you are urged to delete your old /modules directory
1206 before booting the new kernel, since kldload will find stale
1207 modules in that directory instead of finding them in the correct
1208 path, /boot/kernel. The most common complaint that this cures
1209 is that the linux module crashes your machine after the update.
1211 if [ ! -d /boot/kernel.old ]; then
1212 mv /modules.old /boot/kernel.old
1213 chflags noschg /kernel.old
1214 mv /kernel.old /boot/kernel.old/kernel.ko
1215 chflags schg /boot/kernel.old/kernel.ko
1219 A new issue with the sendmail upgrade has come to light.
1220 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1221 incorrectly install the default aliases in /etc/mail rather than
1222 move the old one from /etc. So you'll need to manually move the
1223 file, create a symbolic link, remove the old /etc/aliases.db and
1224 run newaliases. For safety sake, you should stop sendmail
1225 while doing this and run the upgrade when locally sourced email
1226 is not likely to be generated.
1229 /boot/device.hints is now required for installkernel to
1230 succeed. You should copy GENERIC.hints for your architecture
1231 into /boot/device.hints. If and only if you compile hints
1232 into your kernel, then this file may be empty. Please note,
1233 if you have an empty or missing /boot/device.hints file and
1234 you neglected to compile hints into your kernel, no boot
1235 messages will appear after the boot loader tries to start the
1239 If you do NOT have ``options RANDOMDEV'' in your kernel and
1240 you DO want the random device then add randomdev_load="YES" to
1244 suidperl is now always built and installed on the system, but
1245 with permissions of 511. If you have applications that use
1246 this program, you are now required to add ENABLE_SUIDPERL=true
1247 to /etc/make.conf. If you forget to do this,
1248 chmod 4511 /usr/bin/suidperl
1249 will fix this until the next build.
1252 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1253 visible changes that may immediately affect your configuration
1255 - New default file locations from src/contrib/sendmail/cf/README
1256 - newaliases limited to root and trusted users
1257 - MSA port (587) turned on by default
1258 - New queue file naming system so can't go from 8.11 -> 8.9
1259 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1260 - FEATURE(`nullclient') is more full featured
1261 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1262 - mail.local FreeBSD-only -b option changed to -B
1263 - See src/contrib/sendmail/RELEASE_NOTES for more info
1266 suidperl (aka sperl) is no longer build by default. You must
1267 specifically define BUILD_SUIDPERL to "true" for it to be build.
1268 Furthermore, we recommend that you remove /usr/bin/sperl* and
1269 /usr/bin/suidperl files from your system unless you have a
1270 specific use for it.
1273 Networking defaults have been tightened. Anybody upgrading
1274 /etc/defaults/rc.conf needs to add the following lines to
1275 /etc/rc.conf if they want to have the same setup
1276 afterwards (unless the variables already are set, of course):
1277 # Enable network daemons for user convenience.
1279 portmap_enable="YES"
1280 sendmail_enable="YES"
1283 If you have null_load="YES" in your /boot/loader.conf, you
1284 will need to change that to nullfs_load="YES".
1287 The "installkernel" target has changed slightly. Now even if
1288 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1289 it will install the MYKERNEL file (built with the buildkernel
1290 target) as /kernel rather than /MYKERNEL. Those who have
1291 updated their /boot/loader.conf files to point to /MYKERNEL
1292 should remove that entry or perform manual rename of /kernel
1296 If you use CVSUP or CTM to get CVS trees, AND you used to get
1297 the old crypto files from internat.freebsd.org AND you check
1298 out files from the CVS tree with the cvs command, please read
1299 http://people.freebsd.org/~imp/internat.txt
1300 for details on potential problems that you might have and how
1303 If you are merely a mirror, or don't answer yes to each of the
1304 clauses above, you needn't worry.
1307 /etc/security has been updated to print the inode number of
1308 setuid programs that have changed. You will see a large spike
1309 in the number of changed programs the first time when you run
1310 mergemaster to get a new /etc/security.
1313 /dev/random now has good entropy collection (from the keyboard
1314 and sysmouse drivers). Please ensure that either `options
1315 RANDOMDEV' is present in your kernel config file or that
1316 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1317 not have the /dev/random driver, OpenSSL (and consequently
1318 lots of crypto tools (like SSH)) will fail with strange
1319 errors. (see below, 20000624).
1321 FreeBSD-current is safe again to run Crypto.
1324 phk made the malloc default options AJ. This may slow things
1325 down and uncover other latent bugs in the code. If you need to
1326 run at full speed, you can disable this by doing the following:
1327 ln -s aj /etc/malloc.conf
1330 libftpio's version was accidentally bumped a few days ago. This
1331 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1332 before doing your next buildworld/installworld pair. It certainly
1333 won't hurt to remove it before the update procedure. It will
1334 break fetch until a new one is built, but ftp can be used in the
1338 The crypto packages have changed for the cvsup. This has been done
1339 in a backward compatible way, but the old packages will go away at
1340 some point in the future. Look at /usr/share/examples/cvsup for
1344 With the new sys/modules/sound/drivers/*, you will need to
1345 set SYSDIR until you do an installworld after July 7th.
1348 rc.shutdown and rc will now call the rc.d scripts with start
1349 or stop. This may cause some harmless warnings from older
1350 rc.d scripts that haven't been updated.
1353 The libfetch based version of fetch has gone into the tree.
1354 Minor problems may result on some of the less popular sites,
1355 which should be reported to des@freebsd.org.
1358 From approximately this date forward, one must have the crypto
1359 system installed in order to build the system and kernel.
1360 While not technically strictly true, one should treat it as
1361 required and grab the crypto bits. If you are grabbing CVS
1362 trees, src-all and cvs-crypto should be treated as if they
1363 were required. You should check with the latest collections
1364 to make sure that these haven't changed.
1367 Mark Murray just committed the first parts of a cleanup of
1368 /dev/zero, et al. This is also cleaning up /dev/random.
1369 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1370 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1371 until Mark can merge in the fixes to this work in progress.
1372 openssh and openssl should not be used to generate keys from this
1373 date to the completion of the work.
1375 If you must operate at this reduced level of security, add '
1376 options RANDOMDEV' to your kernel or modload the randomdev
1377 module. You may also need to copy a new MAKEDEV to /dev and
1378 recreate the random and urandom devices.
1381 The license on the softupdates is now a standard 2 clause
1382 BSD license. You may need to remove your symbolic links
1383 that used to be required when updating.
1386 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1387 the config file update procedure.
1388 http://people.freebsd.org/~imp/config-upd.html
1389 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1390 isn't buildable. However, you can generate a LINT file:
1391 cd /sys/<ARCH>/conf && make LINT
1394 Binutils 2.10 have hit the tree, or will shortly. As soon
1395 as they do, the problem noted in 20000522 will be resolved and
1396 that workaround will no longer be required.
1399 phk removed the compatibility creation of wd devices in the
1400 ad driver. If you haven't done so already, you must update
1401 your fstab, etc to use the ad devices instead of the wd
1404 In addition, you'll need to update your boot blocks to a
1405 more modern version, if you haven't already done so. Modern
1406 here means 4.0 release or newer (although older releases
1410 Peter took an axe to config(8). Be sure that you read his mail
1411 on the topic before even thinking about updating. You will
1412 need to create a /boot/device.hints or add a hints directive
1413 to your config file to compile them in statically. The format
1414 of the config file has changed as well. Please see GENERIC or
1415 NEWCARD for examples of the new format.
1417 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1418 says that it has been fixed, assume that must use the hints mechanism
1419 in the loader if you need to use a machine with very old ISA cards
1423 A new set of binutils went into the tree today. Anybody
1424 building a kernel after this point is advised that they need
1425 to rebuild their binutils (or better yet do a
1426 buildworld/installworld) before building a new kernel.
1428 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1429 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1430 is recommended that you don't set this option until the problem
1434 The ethernet drivers were all updated to clean up the BPF handling.
1437 The problems with boot blocks on the alphas have been corrected.
1438 This will require some care in updating alphas. A new libstand
1439 is requires for the boot blocks to build properly.
1442 Recompile all kld modules. Proper version dependency info
1446 Modules have been disconnected from the buildworld tree and
1447 connected to the kernel building instead.
1450 You may need to build gperf
1451 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1452 when upgrading from 4.0 -> current. The build system now uses
1453 an option only in -current.
1456 The method that we brand ELF binaries has changed to be more
1457 acceptable to the binutils maintainers. You will need to
1458 rebrand your ELF binaries that aren't native. One problem
1459 binary is the Linux ldconfig. After your make world, but
1460 before you reboot, you'll need to issue:
1461 brandelf -t Linux /compat/linux/sbin/ldconfig
1462 if you have Linux compatibility enabled on your machine.
1465 If you have really bad/marginal IDE drives, you may find they
1466 don't work well. Use pio mode instead. The easiest way to
1467 cope if you have a problem combination is to add:
1468 /sbin/sysctl hw.ata.ata_dma=0
1469 to the start of /etc/rc.conf.
1472 The ISA and PCI compatibility shims have been connected to the
1473 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1474 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1475 include the appropriate option in your kernel config. Drivers
1476 using the shims should be updated or they won't ship with
1477 5.0-RELEASE, targeted for 2001.
1480 We've entered the traditional post release dumping party.
1481 Large kernel changes are being committed and are in the
1482 works. It is important to keep the systems' klds and kernel
1483 in sync as kernel interfaces and structures are changing.
1484 Before reporting kernel panics, make sure that all modules
1485 that you are loading are up to date.
1488 If you are upgrading from an older version of FreeBSD, you
1489 need to update your boot blocks as well. 'disklabel -B ad0'
1490 will do the trick. This isn't critical until you remove your
1491 wd device entries in /dev, at which point your system will not
1495 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1496 to upgrade to 4.0 from 3.x.
1502 Avoid using make -j when upgrading. From time to time in the
1503 past there have been problems using -j with buildworld and/or
1504 installworld. This is especially true when upgrading between
1505 "distant" versions (eg one that cross a major release boundary
1506 or several minor releases, or when several months have passed
1507 on the -current branch).
1509 Sometimes, obscure build problems are the result of environment
1510 poisoning. This can happen because the make utility reads its
1511 environment when searching for values for global variables.
1512 To run your build attempts in an "environmental clean room",
1513 prefix all make commands with 'env -i '. See the env(1) manual
1514 page for more details.
1518 If you are updating from a prior version of FreeBSD (even one just
1519 a few days old), you should follow this procedure. With a
1520 /usr/obj tree with a fresh buildworld,
1521 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1522 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1524 To just build a kernel when you know that it won't mess you up
1525 --------------------------------------------------------------
1526 This assumes you are already running a 5.X system. Replace
1527 ${arch} with the architecture of your machine (e.g. "i386",
1528 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1530 cd src/sys/${arch}/conf
1531 config KERNEL_NAME_HERE
1532 cd ../compile/KERNEL_NAME_HERE
1537 If this fails, go to the "To build a kernel" section.
1539 To rebuild everything and install it on the current system.
1540 -----------------------------------------------------------
1541 # Note: sometimes if you are running current you gotta do more than
1542 # is listed here if you are upgrading from a really old current.

1558 To cross-install current onto a separate partition
1559 --------------------------------------------------
1560 # In this approach we use a separate partition to hold
1561 # current's root, 'usr', and 'var' directories. A partition
1562 # holding "/", "/usr" and "/var" should be about 2GB in

1573 ${CURRENT_ROOT}/boot/device.hints # as needed

1575 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1576 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd

1578 <reboot into current>
1579 <do a "native" rebuild/install as described in the previous section>
1580 <maybe install compatibility libraries from /usr/src/lib/compat>
1584 To upgrade in-place from 4.x-stable to current
1585 ----------------------------------------------
1586 # 5.x uses more space than 4.x. Also, the location of kernel
1587 # modules has changed. If you are installing 5.0 onto a 4.x
1588 # system, you'll need about 30MB of free disk space on your /
1589 # partition. If you have less than this, you may encounter difficult
1590 # to back out of problems with this procedure. If /tmp is on
1591 # the / partition, you may want to completely remove all its content
1592 # before upgrading, as this can be a common source of shortage of

1598 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
1599 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
1600 make installkernel KERNCONF=YOUR_KERNEL_HERE
1601 cd sys/boot ; make STRIP="" install [6]

1606 rm -rf /usr/include/g++
1611 Make sure that you've read the UPDATING file to understand the
1612 tweaks to various things you need. At this point in the life
1613 cycle of current, things change often and you are on your own
1614 to cope. The defaults can also change, so please read ALL of
1615 the UPDATING entries.
1617 Also, if you are tracking -current, you must be subscribed to
1618 freebsd-current@freebsd.org. Make sure that before you update
1619 your sources that you have read and understood all the recent
1620 messages there. If in doubt, please track -stable which has
1621 much fewer pitfalls.
1623 [1] If you have third party modules, such as vmware, you
1624 should disable them at this point so they don't crash your
1627 [2] If you have legacy ISA devices, you may need to create
1628 your own device.hints to reflect your unique hardware
1631 [3] From the bootblocks, boot -s, and then do
1636 adjkerntz -i # if CMOS is wall time
1637 Also, when doing a major release upgrade, it is required that
1638 you boot into single user mode to do the installworld.
1639 For the 4.x -> 5.0 upgrade, you will also see many messages about
1640 needing to recompile your userland. These are harmless and can
1641 be ignored while you proceed to the next step.
1643 [4] Note: This step is non-optional. Failure to do this step
1644 can result in a significant reduction in the functionality of the
1645 system. Attempting to do it by hand is not recommended and those
1646 that pursue this avenue should read this file carefully, as well
1647 as the archives of freebsd-current and freebsd-hackers mailing lists
1648 for potential gotchas.
1650 [5] Usually this step is a noop. However, from time to time
1651 you may need to do this if you get unknown user in the following
1652 step. It never hurts to do it all the time. You may need to
1653 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1654 install) after the buildworld before this step if you last updated
1655 from current before 20020224 or from -stable before 20020408.
1657 [6] 4.x boot loader can be used to boot a 5.x system, however
1658 it is difficult to do that at best. If you wish to try, then
1659 you should interrupt the boot and at the ok prompt type:
1661 ok boot /boot/kernel/kernel
1662 If this fails to work, you must install a new boot loader as
1665 [7] Before you upgrade, please make sure that you are not using
1666 compatibility slices. These are device names of the form, on i386
1667 and other architectures that use MBR slicing, /dev/ad0a without the
1668 actual slice name. Chances are excellent that these will break.
1669 You generally must update these entries to use the post FreeBSD
1670 2.x form of /dev/ad0s1a.
1672 [8] In order to have a kernel that can run the 4.x binaries
1673 needed to do an installworld, you must include the COMPAT_FREEBSD4
1674 option in your kernel. Failure to do so may leave you with a system
1675 that is hard to boot to recover.
1677 [9] When checking out sources, you must include the -P flag to have
1678 cvs prune empty directories. Also, if CPUTYPE is defined in your
1679 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1680 operator, so that buildworld can override the CPUTYPE if it needs to.
1681 In case you would like to avoid installing new packages of everything,
1682 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1683 compatibility libraries are build which should allow you to continue
1684 using your existing software for a while.
1686 [10] In order to create temporary files, /dev/random must be
1687 initialized by feeding data into it. /etc/rc.d/preseedrandom
1691 This file contains a list, in reverse chronological order, of major
1692 breakages in tracking -current. Not all things will be listed here,
1693 and it only starts on March 15, 2000. Updating files can found in
1694 previous releases if your system is older than this.
