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25 The RANDOM_IP_ID option has been replaced by the sysctl
26 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
27 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
30 The size of 'struct ifnet' has changed due to the addition of the
31 if_carp placeholder. All kernel modules implementing network
32 interfaces must be recompiled as a result.
35 Module loading has been fixed. Some older installations will
36 drop proper module_path initialization and modules will fail to
37 load properly. If you have a line in /boot/loader.rc that says:
38 "initialize drop", do (i386 only):
39 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
40 chown root:wheel /boot/loader.rc
41 chmod 444 /boot/loader.rc
44 making /dev/(null|zero) into a module proved to be too unpopular,
45 so this bit has been revoked from the previous (20040801) entry.
48 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
49 so you may wish to add them to your kernel config file. See
53 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
54 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
55 has broken C++ ABI compatibility with previous releases yet again
56 and users will have to rebuild all their C++ programs with the new
57 compiler. A new unit-at-a-time optimization mode, which is default
58 in this compiler release, is more aggressive in removing unused
59 static symbols. This is the likely cause of 'make buildworld'
60 breakages with non-default CFLAGS where optimization level is set
63 With the upgrade of the system compiler, the kernel has been upgraded
64 to match the new system compiler. This makes it impossible to build
65 a new kernel with the old compiler. Upgrade your system via
66 make buildworld and make kernel (see below) to fix this problem.
69 The size of 'struct ifnet' has changed due to the addition of
70 the IFF_NEEDSGIANT flag (and what it implies). All kernel
71 modules implementing network interfaces must be recompiled as
75 The sound device drivers are renamed. `sound' is always required,
76 while `snd_*' should be configured accordingly to your hardware.
77 Refer to NOTES for the detail of the drivers.
80 __FreeBSD_version bumped to 502122.
83 The console initialization on Alpha has been reworked and is now
84 identical to other platforms. This means that the hardcoding of
85 the serial console and the debug port has been removed. As such,
86 hints are now required for the sio(4) driver to become a console
87 or debug port. The NO_SIO option has been decommissioned because
91 A revamp of the debugging code in the kernel with some visible
92 changes beyond just the debugging experience:
93 o The DDB option is now specific to the DDB debugger backend
94 and should not be used any more for conditional compilation
95 of debugging code for when debugging is enabled. Use the KDB
97 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
98 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
99 respectively. This is in line with the first bullet.
100 o The remote GDB support has been untangled from DDB and needs
101 to be enabled separately now. Use the GDB option for this.
102 o The GDB_REMOTE_CHAT option has been removed. Support for this
103 homegrown feature is discontinued. The GDB remote protocol
104 supports console output and it makes sense to use that.
105 o The DDB_NOKLDSYM option has been removed. The DDB debugger
106 now supports both direct symbol table lookups as well as KLD
107 symbol lookups through the linker.
110 Bluetooth code has been marked as non-i386 specific.
111 __FreeBSD_version has been bumped to 502121 to mark this change.
114 The native preemption has been added to the kernel scheduler.
115 There is some report that the ULE scheduler was broken in some
116 machines and we encourage users using the ULE scheduler either
117 stick with a known good kernel, or temporarily switch to the 4BSD
118 scheduler as a workaround.
121 The netgraph ABI version number has been incremented to indicate
122 an incompatible change in the ABI. Old netgraph nodes will refuse
123 to attach until recompiled. Netgraph now uses mbuf tags to move
124 metadata and this commit removes its home-grown metadata facility.
125 Nodes should just recompile, unless they use metadata, in which
126 case the changes are simple; the file ng_ksocket.c serves as an
127 example of such changes.
129 This also broke i4b, although the compile problem has been papered
133 ACPI has been updated to disable known-bad BIOS revisions. A message
134 will be printed on the console indicating that ACPI has been disabled
135 automatically and that the user should use a newer BIOS, if possible.
136 If you think ACPI does work on your system and want to override
137 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
141 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
142 separated now. It uses the newly created "_pflogd" user/group
143 combination. If you plan to use pflogd(8) make sure to run
144 mergemaster -p or install the "_pflogd" user and group manually.
147 Network interface cloning has been overhauled. This change will
148 require a recompile of modules using cloning and modification of
149 external ones to the new API. __FreeBSD_version has been bumped
150 to 502119 to mark this change. Additionally, users creating
151 stf(4) interfaces via "ifconfig stf" will need to update their
152 scripts as this will create an interface named "stf" instead of
153 "stf0" and ifconfig will not print "stf0" to stdout.
156 On 20040524, the /etc/rc.d/nsswitch script was modified to
157 automatically create /etc/nsswitch.conf on startup if it did
158 not already exist. Unfortunately, an error in the man page
159 was carried over to the script, resulting in incorrect
160 nsswitch settings. The simplest remedy is to remove both
161 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
162 during the next reboot.
165 The return value of sema_timedwait(9) has been changed to
166 make it consistent with cv_timedwait(9). Be sure to recompile
167 the ips module and any third-party modules which call
171 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
172 Make sure to recompile modules and any userland that makes use of
173 sizeof(struct ifnet). In order to get the altq headers in place
174 please recompile and reinstall world.
177 Splitting kern_thread.c into 2 files (adding kern_kse.c)
178 requires that you re-run config after updating your tree.
181 The MIDI drivers have been removed. Until the new module-friendly
182 ones are merged, remove or comment out midi and seq from your
183 kernel configuration.
186 Due to a new option in ipfw (versrcreach) the ipfw(8) command
187 needs to be recompiled. Normal accept/reject rules without
188 options are not affected but those with options may break until
189 ipfw(8) is recompiled.
192 Due to changes in the callout ABI, kernels compiled after this
193 date may be incompatible with kernel modules compiled prior to
197 The PCI bus power state stuff has been turned on. If this causes
198 problems for your system, please disable it using the tunable
199 hw.pci.do_powerstate=0.
202 The bulk of the pci problems have been fixed, although the floppy
203 drive is still broken.
206 A substantial update to the pci bus resource and power management
207 have been committed. Expect a bumpy ride for a few days until
208 the unanticipated problems have been resolved.
211 Due to changes in the the Yarrow initialization process,
212 /dev/random needs to be fed before operations requiring
213 temp files can succeed in single user mode. This includes
214 running "make installworld". /dev/random may be fed by running
215 "/etc/rc.d/initrandom start" or with 20040415 source by running
216 "/etc/rc.d/preseedrandom".
219 The debug.mpsafenet tunable controls whether the kernel Giant
220 lock is held across the lower levels of the network stack, and
221 by default is turned off. In the few days following 20040322,
222 the behavior of debug.mpsafenet will change such that this
223 tunable controls Giant over all levels of the network stack.
224 If you are currently setting debug.mpsafenet to 1, you should
225 set it back to 0 (the default) again during the change-over.
226 An additional note will be added to UPDATING when sufficient
227 locking is merged to permit this to take place.
230 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
231 64-bits. This is a very major incompatible change, so people
232 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
233 detailed instructions on how to make this upgrade. People
234 upgrading FreeBSD on other platforms can ignore this event.
237 The packet filter (pf) is now installed with the base system. Make
238 sure to run mergemaster -p before installworld to create required
239 user account ("proxy"). If you do not want to build pf with your
240 system you can use the NO_PF knob in make.conf.
241 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
242 pf system consists of the following three devices:
244 device pflog # optional
245 device pfsync # optional
248 If you are having trouble with the libc_r -> libpthread transition
249 (see the 20040130 entry), place the following lines at the top of
252 libc_r.so.5 libpthread.so.1
253 libc_r.so libpthread.so
255 This will cause all programs and libraries linked against libc_r
256 to use libpthread instead.
259 Some sshd configuration defaults have changed: protocol version 1
260 is no longer enabled by default, and password authentication is
261 disabled by default if PAM is enabled (which it is by default).
262 OpenSSH clients should not be affected by this; other clients may
263 have to be reconfigured, upgraded or replaced.
266 The ABIs defined in <resolv.h> and <netdb.h> have been updated
267 to support improved reentrancy. Multi-threaded programs that
268 reference the "_res" or "h_errno" symbols may experience some
269 problems if they are not recompiled. Single-threaded programs
270 should remain unaffected.
273 routed has been updated in the base system from the vendor
274 sources, routed v2.27, from rhyolite.com. This change means that
275 for users who use RIP's MD5 authentication feature, FreeBSD
276 -CURRENT's routed is now incompatible with previous versions
277 of FreeBSD; however it is now compatible with implementations
278 from Sun, Cisco and other vendors.
281 The tcpcb structure has changed and makes a recompile of libkvm
282 and related userland network utilities necessary.
285 The cdevsw structure has changed in two externally visible ways.
286 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
287 Second, the d_version field must be filled in with D_VERSION.
288 Drivers outside the tree will need to be updated.
291 The /etc/rc.d/ttys script has been removed. It is no longer
292 necessary since devfs has been mandatory for some time.
295 libkse has been renamed back to libpthread and is now the
296 default threads library. The gcc -pthread option has also
297 been changed to link to libpthread instead of libc_r. For
298 alpha and sparc64 machines, libkse is not renamed and links
299 are installed so that libpthread points to libc_r. Until
300 the ports system is updated to handle this change, it is
301 recommended that folks install an /etc/libmap.conf(5) that
302 maps libc_r to libpthread. If you have any binaries or
303 libraries linked to libkse, then it is also recommended
304 that you map libkse to libpthread. Anyone that is using
305 nvidia supplied drivers and libraries should use a libmap.conf
306 that maps libpthread to libc_r since their drivers/libraries
307 do not work with libpthread.
310 ULE has entered into its probationary period as the default scheduler
311 in GENERIC. For the average user, interactivity is reported to be
312 better in many cases. On SMP machines ULE will be able to make more
313 efficient use of the available parallel resources. If you are not
314 running it now, please switch over, replacing the kernel option
315 SCHED_4BSD with SCHED_ULE.
318 Move LongRun support out of identcpu.c, where it hardly
319 belongs, into its own file and make it opt-in, not mandatory,
320 depending on CPU_ENABLE_LONGRUN config(8) option.
323 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
324 if the login process is unable to successfully set the
325 process credentials to include all groups defined for the
326 user. The current kernel limit is 16 groups; administrators
327 may wish to check that users do not have over 16 groups
328 defined, or they will be unable to log in.
331 The ACPI module has been reactivated. It is no longer required
332 to compile ACPI support into kernels statically.
335 The statfs structure has been updated with 64-bit fields to
336 allow accurate reporting of multi-terabyte filesystem
337 sizes. You should build world, then build and boot the new kernel
338 BEFORE doing a `installworld' as the new kernel will know about
339 binaries using the old statfs structure, but an old kernel will
340 not know about the new system calls that support the new statfs
342 Note that the backwards compatibility is only present when the
343 kernel is configured with the COMPAT_FREEBSD4 option. Since
344 even /bin/sh will not run with a new kernel without said option
345 you're pretty much dead in the water without it. Make sure you
346 have COMPAT_FREEBSD4!
347 Running an old kernel after a `make world' will cause programs
348 such as `df' that do a statfs system call to fail with a bad
349 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
350 that cfsd (ports/security/cfs) needs to be recompiled after
351 these changes are installed.
353 ****************************DANGER*******************************
355 DO NOT make installworld after the buildworld w/o building and
356 installing a new kernel FIRST. You will be unable to build a
357 new kernel otherwise on a system with new binaries and an old
361 Some netgraph string length constants have been changed. This
362 change requires the netgraph kernel modules and all netgraph
363 userland components to be in sync. Especially users who require
364 netgraph to boot need to make sure to have world and kernel in
365 sync before rebooting.
368 Hyperthreading logical CPU's are no longer probed by default
369 when using the MP Table. If ACPI is being used, then logical
370 CPUs will be probed if hyperthreading is enabled in the BIOS.
371 If ACPI is not being used and hyperthreading is enabled in the
372 BIOS, logical CPUs can be enabled by building a custom kernel
373 with the option MPTABLE_FORCE_HTT enabled.
376 The i386 APIC_IO kernel option has been replaced by
377 'device apic'. The ACPI module has also been temporarily
378 disabled, so ACPI must be statically compiled into your
379 kernel using 'device acpi' if you wish to use the ACPI driver.
382 The API and ABI of struct ifnet have been changed by removing
383 the if_name and if_unit members and replacing them with
384 if_xname, if_dname, and if_dunit. All network drivers and most
385 userland programs which include net/if_var.h must be updated
386 and recompiled. __FreeBSD_version has been bumped to 501113 to
390 Changes to the cdevsw default functions have been made to remove
391 the need to specify nullopen() and nullclose() explicitly.
392 __FreeBSD_version bumped to 501110.
395 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
396 mount_cd9660(8) need to be in sync with kernel.
399 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
400 also be explicitly configured. Previously this dependency was
401 magically handled through some cruft in net/pfil.h; but that has
402 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
403 will fail with obtuse errors in ip_fil.c.
406 Fix a bug in arplookup(), whereby a hostile party on a locally
407 attached network could exhaust kernel memory, and cause a system
408 panic, by sending a flood of spoofed ARP requests. See
409 FreeBSD-SA-03:14.arp.
412 A change to /etc/defaults/rc.conf now causes inetd to be started
413 with `-C 60' if it is not overridden in /etc/rc.conf. This
414 causes inetd to stop accepting connections from an IP address
415 that exceeds the rate of 60 connections per minute.
418 The following rc.d scripts have been removed and should be
419 deleted from your installation: atm2.sh atm3.sh devdb
420 localdaemons network1 network2 network3. Depending on when
421 you last updated world and used mergemaster(8) you may or
422 may not have problems during the rc boot sequence. The simplest
423 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
424 The atm2.sh atm3.sh and devdb scripts were removed some time
425 ago, so depending on when you installed -CURRENT these scripts
426 may or may not exist on your system.
429 ATAng has been committed. You need to build world as sys/ata.h
430 has changed, and userland atacontrol depends on it.
431 If you use ATA SW raids you need "device ataraid" in your
432 kernel config file, as it is no longer pulled in automatically.
435 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
436 Among other things, this changes the device enumeration to be
437 closer to Solaris. Be aware that, this can even cause the machine
438 to not boot without manual intervention before the fstab is adjusted.
441 All current USB and Firewire quirks in da(4) have been deprecated
442 and will be removed for 5.2. If this causes failure for your
443 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
444 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
445 so the quirk can be re-enabled.
448 Problems with entry 20030714 have been corrected and no known issues
449 with /rescue and -j exist for host systems after this point in time.
452 FPU-less support has been removed from FreeBSD. Chances are you won't
453 notice. 386+387 support should still work after this change, but
454 it is now a minimum requirement for the i386 port that you have real
458 Some people are having problems with changes related to /rescue.
459 If you are building -j N, you will need to define NO_RESCUE. Others
460 will need to define it if /rescue has issues with their environment.
461 People should report those issues to current@.
464 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
465 across this point. Further, it might be a good idea to remove
469 Remove deprecated locale names and transition period code
470 for them, finishing switching to the new scheme. Check your
471 LANG environment variable.
474 CCD has been changed to be a fully GEOMified class. Kernel
475 and ccdconfig(8) needs to be in sync, this is particularly
476 important to remember beforehand if your source tree is on
477 a ccd device. Consider making a copy of the old ccdconfig
478 into /boot/kernel.good or wherever you keep your backup
482 There was a small window in which sed(1) was broken. If you
483 happen to have sed(1) installed during that window, which is
484 evidenced by an inability to build world with the failure
485 given below, you need to manually build and install sed(1)
486 (and only sed(1)) before doing anything else. This is a one-
487 time snafu. Typical failure mode:
489 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
490 targmatch.h:7:1: null character(s) ignored
491 targmatch.h:12:1: null character(s) ignored
492 targmatch.h:16:1: null character(s) ignored
495 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
496 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
497 usr.bin/sed/process.c).
500 Kerberos 5 (Heimdal) is now built by default. Setting
501 MAKE_KERBEROS5 no longer has any effect. If you do NOT
502 want the "base" Kerberos 5, you need to set NO_KERBEROS.
505 groff has been updated. If you try to do a buildworld and
506 get an infinite loop in troff, update to May 4th or newer. If you
507 have a newer kernel than userland, you may need to set the OSRELDATE
508 to 500110 in your environment before starting a buildworld.
511 The old rc system has been removed. Please report any problems
512 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
513 Your personal versions of these files will not be removed, so you can
514 continue to use them. However, you should take great care when updating,
515 especially when using mergemaster, since the compatibility code that
516 utilizes these old scripts has also been removed.
519 A bug has been fixed in /dev/devctl which would cause devd
520 to hang on boot, were it not for a workaround in devd. The
521 work around in devd will be removed around 20030507. You
522 have until then to upgrade your kernel before updating
523 userland. In general, you should have a userland and
524 kernel that's in sync with each other. However, given the
525 effects of this bug (hang on boot when starting devd), some
529 Alphas with libc from between 20030312 and 20030329 exhibit
530 floating point exceptions (FPEs), most notably in awk(1)
531 while upgrading the system through a buildworld.
533 So, to successfully upgrade your Alpha, you must either
534 downgrade your libc.so to a pre-20030312 version, or update
535 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
536 to CFLAGS, then forcibly rebuild and install libc:
538 cd /usr/src/lib/libc && \
539 make cleandir && make obj && \
540 make -DNOMAN -DNOPROFILE all && \
541 make -DNOMAN -DNOPROFILE install
544 sendmail 8.12.7 has been imported. It has one important
545 change for IPv6 users. The default submit.mc now uses
546 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
547 used to connect to the MTA. Users on IPv6-only machines
548 will need to edit /etc/mail/submit.mc appropriately.
551 NODEVFS option has been removed and DEVFS thereby made standard.
552 This makes all references to MAKEDEV obsolete, and they should
553 be removed when convenient.
556 The name of the device for the ofw console has changed, sparc64 users
557 must run mergemaster to update their installed /etc/ttys.
560 The scheduler framework has grown a second scheduler and consequently
561 you must specify one and only one scheduler in your kernel config.
562 The cvs config files have been updated to use the old scheduler
563 which may be selected via 'options SCHED_4BSD'. If you would like
564 to try the new, much more experimental, scheduler please try
565 'options SCHED_ULE' and contribute to the arch@ discussion.
568 A new version of the wi driver has been imported into the tree.
569 One now must have device wlan in the config file for it to operate
572 In addition, there have been some changes to how wi devices are
573 configured for point to point links to bring it more in line
574 with the former way of doing things, as well as compatibility
578 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
579 used an incompatible form of ABI for returning structures and unions
580 which FreeBSD's GCC maintainers were not aware of relative to previous
581 versions of FreeBSD. We have gone back to the ABI for now, and any
582 code compiled which is required to interoperate with other code (not
583 built at the same time) returning structs or unions should be
587 A name change in /etc/netconfig has been reverted to stay
588 compatible with suns TIRPC and also with NetBSD. You need
589 to run mergemaster after make world. A new libc does still work
590 with an outdated /etc/netconfig for some time, but you'll get
591 a warning. This warning will be removed in 20030301.
594 The recent binutils upgrade marks a kernel flag day on
595 sparc64: modules built with the old binutils will not work
596 with new kernels and vice versa. Mismatches will result in
597 panics. Make sure your kernel and modules are in sync.
600 The value of IPPROTO_DIVERT has changed. Make sure to keep
601 your kernel, netstat, natd and any third-party DIVERT
605 Old, compatibility slices have been removed in GEOM kernels.
606 This means that you will have to update your /etc/fstab to
607 not use disk devices of the form /dev/ad0a. Instead, you
608 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
609 partition really is on. The old device names have gone
610 away, so if you use them anywhere else, you must also adjust
611 those uses. (This doesn't affect the disks formatted in
612 the ``dangerously-dedicated'' mode.)
615 Alphas with kernels from between 20020830 and 20021023 and/or
616 rtld (ld-elf.so.1) older than 20021023 may experience problems
617 with groff while doing a buildworld (kernel: "out of memory",
618 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
619 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
621 So, to successfully upgrade your Alpha, you must either
622 upgrade your kernel and rtld first (which might be a bit
623 tricky), or avoid running the bootstrapped groff during the
624 "transitional" buildworld. To avoid running groff during the
625 transitional upgrade run make buildworld with -DNOMAN,
626 -DNO_SHAREDOCS, and -DNO_LPR.
629 gcc has been upgraded to 3.2. It is not all binary compatible
630 with earlier versions of gcc for c++ programs. All c++
631 programs and libraries need to be recompiled.
633 Also, if you encounter g++ issues, rm /usr/include/g++/* before
634 doing an installworld to make sure that stale files are removed.
637 Our /etc/termcap now has all the entries from the XFree86 xterm
638 almost unchanged. This means xterm now supports color by default.
639 If you used TERM=xterm-color in the past you now should use
640 TERM=xterm. (xterm-color will lead to benign warnings).
643 A "bug" in gcc(1) that was hiding warning in system headers was
644 fixed. It's probably time to add -DNO_WERROR to your make line
648 COPY is being deprecated. The 20010530 change was reverted, as
649 it causes far more pain than was expected, and to always compare
650 before installing, please use INSTALL="install -C" again. The
651 -C option is now silently ignored when used with the -d option.
654 Problems with libc_r clients like KDE and GNOME have been resolved.
655 There are still some minor problems with some signals but the
656 system is stable enough for general use again. SMP is less so than UP
657 but each can successfully complete multiple buildworlds.
658 Libkvm needs to be recompiled due to KSE.
661 Now would be a bad time to upgrade. Something in or near the
662 KSE commit totally broke programs using libc_r like KDE and
666 The k5su utility installed as part of Kerberos 5 is no longer
667 installed with the set-user-ID bit set by default. Add
668 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
669 with the set-user-ID bit set.
672 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
673 Unfortunately our native GDB (at version 4.18) does not understand
674 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
675 generated debugging information for our native GDB.
678 Due to the way CVS works, it may not properly update src/contrib/gcc
679 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
680 and then do a cvs update.
683 When exec'ing set[ug]id executables, the kernel now ensures that the
684 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
687 New sendmail startup scripts have been installed to make it
688 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
689 variable sendmail_enable to "NO" no longer prevents any sendmail
690 daemons from starting. Instead, either set sendmail_enable to
691 "NONE" or change mta_start_script to a script for starting
692 an alternative MTA. Setting mta_start_script to "" will
693 also prevent any MTA from being started at boot.
696 UCONSOLE is no longer a valid kernel option.
699 FreeBSD 5.0 DP-1 was basically branched today.
702 Warnings are now errors in the kernel. Unless you are a developer,
703 you should add -DNO_WERROR to your make line.
706 sendmail 8.12.2 has been imported. The sendmail binary is no
707 longer a set-user-ID root binary and the infrastructure to support
708 command line mail submission has changed. Be sure to run
709 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
710 and /etc/mail) and read /etc/mail/README for more details.
712 Due to the import of sendmail 8.12.2, a new user and group are
713 required in order for sendmail to run as a set-group-ID
714 binary. A 'make installworld' will use the new user and group
715 to set the owner and group of /var/spool/clientmqueue and will
716 fail if the new user and group do not exist. The 'smmsp' user
717 and group must be merged from src/etc/group and
718 src/etc/master.passwd before using 'make installworld'.
719 'mergemaster -p' will do this. You may need to install
720 mergemaster before this will work if you are updating from a
721 very old version of current. The updating recipe has changed
725 The preferred configuration method for PAM is now /etc/pam.d/
726 rather than /etc/pam.conf. If you have an unmodified
727 pam.conf, just delete it after your next mergemaster run. If
728 you have local modifications, you can use
729 /usr/src/etc/pam.d/convert.pl to incorporate them into your

740 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
741 started out its life in the ISDN4BSD project as an offspring
742 from sys/net/if_spppsubr.c, which eventually got a life of its
743 own. All the accumulated features and bug fixes of the i4b
744 version have now been merged back into the base system's
745 version now. The only user-visible change resulting from this
746 is that i4b's sppp(4) interfaces are to be managed with
747 spppcontrol(8) again, since ispppcontrol(8) has been retired
748 as well. (There has never been rc file support for
749 ispppcontrol in -current, but only in -stable. That will be
750 reverted by the time the changes are MFCed.)
753 The fdc(4) driver has been updated and now automatically
754 recognizes media in `standard' formats (like 1440 KB and
755 720 KB for a 3.5" high-density drive) when accessing the
756 default device node (e. g. /dev/fd0). The old variety of
757 floppy device nodes /dev/fd*.* is no longer present by
758 default, devices can be created (in DEVFS) on demand. They
759 will need to be customized then for `odd' densities using
763 The bugs in procfs' debugging support code have been fixed,
764 and truss(1) now works again.
767 Daily security checks have been split out to use the periodic(8)
768 scripts. Some change in configuration may be necessary. Please
770 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
774 sos added VCD/SVCD support to ata driver and that needs the
775 kernel and burncd to be in sync.
778 The procfs pseudo-filesystem has now been converted to use the
779 pseudofs framework. If you have 'options PROCFS' in your
780 kernel config, you'll need to add 'options PSEUDOFS' if it's
783 This change temporarily breaks truss(1); use ktrace(1) instead
784 until the issue has been resolved.
787 A security hole in OpenSSH involving `UseLogin yes' has been
791 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
792 after this date. You need to do this only once.
795 Most of the awk issues have been resolved. Some rough
796 edges may be left, but for the most part things should be
797 back to "normal." For CURRENT's usual definition of "normal."
800 Awk has been upgraded to the one true awk from bell labs. Expect
801 choppy waves in the upgrade process.
804 The asr driver problem has been resolved.
807 Due to changes in other parts of the system, the asr driver
808 now causes the system to panic on boot. Do not use it pending
809 correction. Comment it out of any kernel config file that you
810 try to use from this date forward.
813 When crossbuilding, use TARGET=xxx where you used to use
814 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
815 unless you are changing both of them. To cross build pc98 on
816 an alpha, for example, you need to set TARGET=pc98 and
820 The kernel interface that burncd depends on has changed.
821 You must recompile both the kernel and userland applications
825 When crossbuilding, please set TARGET_ARCH rather than
826 MACHINE_ARCH to indicate the target. In the future, one will
827 set TARGET_MACHINE where you set MACHINE now. At the moment,
828 setting MACHINE alone for same MACHINE_ARCH machines works
829 (eg, you can build pc98 on an i386 machine and vice versa).
832 Some weird problems result from using ACPI on some machines.
833 To disable ACPI you can add
834 hint.acpi.0.disabled="1"
835 to /boot/loader.conf (or by putting set X=Y at the boot
838 Alternatively, you can remove it from /boot/kernel/acpi.ko
839 or use the MODULES_OVERRIDE function in your kernel config
840 file and not list acpi in that list.
843 The buildworld has been fixed. You may need to install
844 the 4.x compatibility libraries for some old binaries
845 to work. Add COMPAT4X=true to your /etc/make.conf to
846 get them installed on every installworld, or execute the
847 following to get them installed only once:
848 cd src/lib/compat/compat4x.<arch>
850 You will see ``__stdoutp undefined'' until you do this.
853 There's a bug in the world build process. The cross-tools
854 are build with the NEW headers, but the OLD libc.a. This
855 leads to all kinds of problems with the new libc. A temporary
857 CFLAGS="-O -pipe -D_OLD_STDIO"
858 before building world when upgrading from 4.x to current. This
859 can be removed afterwards.
861 A proper fix to the buildworld target is needed.
864 Peter has committed his new kthread nfs client/server code.
865 NFS may be unstable after this date.
868 KSE has hit the tree. Lots of things are now different in
869 the kernel. While a few problems were introduced in the
870 initial commit, most of the major ones have been found and
874 In OLDCARD, CardBus bridges appear to be stable. The work
875 arounds described in the 20010604 entry are now no longer
876 necessary and will be ignored. Most insert/remove problems
877 have been rectified around this date.
880 named now runs as user bind and group bind rather than as
881 root. If named_enable is set to YES in /etc/rc.conf, ensure
882 that user bind is available in /etc/passwd (using vipw(8))
883 and that group bind is available in /etc/group. Also make
884 sure that user or group bind has read (and not write)
885 permission for your name server configuration and that it
886 has read and write permission for your slave zone files and
889 If you wish to continue to run named as root (a less secure
890 alternative), add a line to /etc/rc.conf saying
895 The PAM libraries have had an API upgrade that is beyond
896 the ability of the shared library major number to handle.
897 It is manifested by PAM-using ports dumping core. The
898 solution is to rebuild those ports.
901 The kernel compile module has moved from src/sys/compile/FOO
902 to src/sys/${MACHINE}/compile/FOO.
905 The pccard modem issue from 20010613 has been corrected.
906 OLDCARD support is still a little weak in -current. slot 1 is
907 known not to work on some TI based cardbus bridges. Some
908 cardbus bridges do not properly detect insert/removal events.
909 IRQ configuration needs more safety belts.
912 Softupdates problems have been corrected.
915 Peter ripped out the linkerset support. You must, as always,
916 rerun config after you cvsup if you are using the traditional
917 kernel building methods.
920 pccard modems may not work with current after 20010604 date. Some
921 do, others result in panics. *MAKE*SURE* that you update your
922 config and /etc/rc.conf ala the 20010604 entry, or you will have
923 problems (this issue will be fixed, it just hasn't been yet).
926 SOFTUPDATES seem to be broken since the middle of May or so. Do not
927 use them in current. You can disable softupdates on all mounted
928 partitions, or remove SOFTUPDATES the kernel config file.
931 After Peter's commits to the hints code, people have been noticing
932 that certain devices are attached (or try to) twice. This is due
933 to having both static hints as well as a /boot/device.hints. To
934 work around this issue, please use only one or the other mechanism
935 until this bug is fixed.
937 Please note that a feature of config is that if you have config
938 file FOO and FOO.hints, it automatically adds FOO.hints to the
939 hints.c file, whether you want it to or not.
942 Locale names have changed to match other systems better.
945 pccard support for pci cards has been committed. You must change
946 your /etc/pccard.conf irq lines. It must match the irq used by
947 pcic device. Interrupt storms may result if you fail to do this.
948 Interrupt storms look a lot like a hang.
950 You must also install a new pccardd, otherwise you will get an
951 interrupt storm at card reset time (just after it tells you what
954 pccardd_flags="-I" is necessary for the time being. It tells pccardd
955 not to ask the kernel if the interrupt is really free or not before
956 using it. You can either change the /etc/pccard.conf irq lines to
957 match pcic, or add "-i X" to the pccardd_flags.
960 INSTALL=install -C is being deprecated. If you want to do this,
961 use COPY=-C instead. The former method will be supported for only
962 a limited time. If you see
964 install: warning: the -d and -C options may not be specified together
966 in your makeworld, then you need to migrate towards using
970 It appears that vm is now stable enough to use again. However,
971 there may be other problems, so caution is still urged. alpha
972 definitely is in bad shape.
975 Minor repo damage has happened. This may cause problems
976 with cvsup of ports. If you get errors, please see
977 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
978 at the bottom for details on a workaround. The error message
980 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
983 Vm and/or swapping are busted on -current. Please be patient.
986 pccard has had much reorganizational work done to it over
987 the past few days. Everything should still work, but if
988 not, please contact imp@freebsd.org.
991 ata ioctl changed. Make sure to recompile both kernel and
992 userland at the same time.
995 New ncurses imported.
998 DEVFS is now opt out, not opt in. Barring major problems, this
999 will be the only way to go starting July 1.
1002 OpenSSH has been updated to 2.9. Some defaults are different,
1003 including RhostsRSAAuthentication, which changes from yes to no.
1006 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
1009 Building perl was broken at 02:25:25 PDT.
1012 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
1013 go back in the water.
1016 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
1017 this date, but before the correction date.
1020 old fsck and new kernel interactions appear to have been fixed.
1023 fsck and the kernel were changed to handle some optimizations
1024 to directory layout. This breaks backward compatibility.
1025 Update only if you understand that you must not use the old
1026 fsck with the new kernel ever.
1029 fsck has changed the meaning of the pass column in /etc/fstab.
1030 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1031 details. It is unclear if changes to /etc/fstab are necessary.
1034 portmap had changed name to rpcbind for maximum POLA in your
1035 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1036 other rpc based programs that rely on portmapper will not work
1037 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1040 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1041 and ATA_ENABLE_TAGS are no longer kernel options. They have
1042 been replaced by tunables. See ata.4 for details.
1045 The fxp driver was converted to use miibus. If you compile
1046 fxp into your kernel statically, you will need to add miibus.
1049 The wi device now defaults to BSS (infrastructure) mode
1053 /dev/urandom should be a symbolic link to /dev/random now.
1054 Users of current not using DEVFS need to run MAKEDEV std.
1055 ssh might not work if you don't.
1058 The ed driver has been updated. It now allows mii attachments,
1059 which means that you must include the miibus in your kernel if
1060 you use the ed driver.
1063 The problems with libc have been corrected. It is now mostly
1064 safe to go back into the water.
1067 The size of FILE was changed. This breaks upgrading. If
1068 you must upgrade, be prepared for pain. It also breaks almost
1069 all binaries that you've compiled on -current. You are warned
1070 that before upgrading would be a good time to do a level 0
1071 dump of your system. No, really, I mean it this time.
1073 To get to the new system, you'll need to use the following
1074 workaround. Hopefully this can be sorted out so that we
1075 don't have to move this to the updating section.
1077 To get around the installworld problem, do:
1078 # cd /usr/src/usr.bin/sed
1082 If that doesn't work, then try:
1083 # make -k installworld
1087 DEVFS is now the default. If you use vinum, make sure that you
1088 do not include devfs in your kernel as problems result.
1091 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1092 Remove them from your config.
1095 ****************************** WARNING ******************************
1096 buildkernel has been changed slightly
1097 ****************************** WARNING ******************************
1098 KERNCONF replaces the variable KERNEL for buildkernel. You
1099 should update your scripts and make.conf accordingly.
1102 config has changed to allow DEV_FOO as a replacement for NFOO.
1103 This requires a new config to build correctly.
1106 The kernel option I386_CPU is now mutually exclusive with the
1107 other cpu types. If you have an i386 system, be sure that it
1108 only had this line. Remove it for all other configurations.
1111 Changes to the kernel require it and burncd be in sync.
1114 Everyone who has hw.sndunit set to something in
1115 /etc/sysctl.conf, it is now hw.snd.unit.
1118 ex and vi were broken by some changes to sys/queue.h. If you
1119 have a bad vi, you will see make buildworld fail with a core
1120 dump while building termcap. You can work around this problem
1121 by adding -k to your make buildworld. This will cause the
1122 build to complete and install a new vi. Once that's done, you
1123 can rebuild again without the -k to pick up anything that
1124 might have been ignored by the -k option.
1126 Others have suggested that you can just rebuild libc if your
1127 vi/ex is dynamically linked, but I've not received any reports
1131 There have been some changes to libcrypt in -current. The
1132 libscrypt/libdescrypt symlink silliness is gone and the installed
1133 libcrypt is fully functional. Be aware of this.
1136 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1137 now require the addition of flag 0x80000 to their config line
1138 in pccard.conf(5). This flag is not optional. These Linksys
1139 cards will not be recognized without it.
1142 Important new FreeBSD-version stuff: PAM support has been worked
1143 in, partially from the "Unix" OpenSSH version. This requires
1144 adding the following in pam.conf:
1146 sshd auth sufficient pam_skey.so
1147 sshd auth required pam_unix.so try_first_pass
1148 sshd session required pam_permit.so
1151 cvs updated to 1.11.
1154 The random device needs more entropy, so you need to make sure
1155 that you've run mergemaster to get a /etc/rc which will seed
1156 /dev/random. If you don't and the system hangs after ldconfig,
1157 then banging on the keyboard randomly until it unhangs is one

1178 The ports tree's new layout is in place. Be sure to update
1179 your entire ports tree, or you will have problems.
1182 The perl build procedure no longer installs miniperl, nor uses
1183 the installed miniperl. It is recommended that you delete
1187 This weekend the ports tree will be updated to a new layout.
1188 It will be in an inconsistent state until noted in the UPDATING
1189 file, or with asami-san's message to the relevant mailing
1190 lists. With this new layout, you'll need to update the whole
1191 tree for anything to work.
1194 There was a change in the passwd format. Need more information.
1197 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1198 place. Please update boot loader (not the boot blocks) at the
1199 same time as your kernel.
1202 The new pmtimer device is necessary for laptops. Failure to
1203 include the device will cause suspended laptops losing time
1204 when they resume. Include
1206 in your config file and
1207 hint.pmtimer.0.at="isa"
1208 to your /boot/device.hints file.
1211 The random device has been turned into a (pseudo-)device,
1212 rather than an option. The supplied kernel config files have
1213 been updated. You will need to do something similar in your
1214 own kernel config file.
1219 If you prefer to load the loadable module, you need to do
1223 The random device module has been renamed from randomdev.ko to
1224 random.ko. You will need to edit your /boot/loader.conf to
1225 reflect this if you load this module at boot time.
1226 The line should read:
1230 The SMPNG commit has happened. It should work, but if it
1231 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1232 to be a variety of minor issues. Please see 20000905 to make
1233 sure you don't have model loading problems which might at
1234 first blush appear related to SMP.
1237 nsswitch has been imported from NetBSD. Among other things,
1238 this means that /etc/host.conf is no longer used. See
1239 nsswitch.conf(5) instead. Note that at boot time rc.network
1240 will attempt to produce a new nsswitch.conf file for you if you
1241 don't have one, and you have host.conf.
1244 The ucred structure changed size. This breaks the interface
1245 that mountd uses. Trying to use an older mountd with a newer
1246 kernel guarantees a panic. This means that you need to use
1247 kernels newer than today only with matching mountd, but you
1248 needed to do that anyway with the boot loader changes.
1251 The boot loader has been updated. The new default kernel is
1252 now /boot/kernel/kernel.ko. The new default module location
1255 You *MUST* upgrade your boot loader and kernel at the same time.
1256 The easiest way to do this is to do the buildworld/buildkernel/
1257 installkernel/installworld dance.
1259 Furthermore, you are urged to delete your old /modules directory
1260 before booting the new kernel, since kldload will find stale
1261 modules in that directory instead of finding them in the correct
1262 path, /boot/kernel. The most common complaint that this cures
1263 is that the linux module crashes your machine after the update.
1265 if [ ! -d /boot/kernel.old ]; then
1266 mv /modules.old /boot/kernel.old
1267 chflags noschg /kernel.old

1275 incorrectly install the default aliases in /etc/mail rather than
1276 move the old one from /etc. So you'll need to manually move the
1277 file, create a symbolic link, remove the old /etc/aliases.db and
1278 run newaliases. For safety sake, you should stop sendmail
1279 while doing this and run the upgrade when locally sourced email
1280 is not likely to be generated.
1283 /boot/device.hints is now required for installkernel to
1284 succeed. You should copy GENERIC.hints for your architecture
1285 into /boot/device.hints. If and only if you compile hints
1286 into your kernel, then this file may be empty. Please note,
1287 if you have an empty or missing /boot/device.hints file and
1288 you neglected to compile hints into your kernel, no boot
1289 messages will appear after the boot loader tries to start the
1293 If you do NOT have ``options RANDOMDEV'' in your kernel and
1294 you DO want the random device then add randomdev_load="YES" to
1298 suidperl is now always built and installed on the system, but
1299 with permissions of 511. If you have applications that use
1300 this program, you are now required to add ENABLE_SUIDPERL=true
1301 to /etc/make.conf. If you forget to do this,
1302 chmod 4511 /usr/bin/suidperl
1303 will fix this until the next build.
1306 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1307 visible changes that may immediately affect your configuration
1309 - New default file locations from src/contrib/sendmail/cf/README
1310 - newaliases limited to root and trusted users
1311 - MSA port (587) turned on by default
1312 - New queue file naming system so can't go from 8.11 -> 8.9
1313 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1314 - FEATURE(`nullclient') is more full featured
1315 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1316 - mail.local FreeBSD-only -b option changed to -B
1317 - See src/contrib/sendmail/RELEASE_NOTES for more info
1320 suidperl (aka sperl) is no longer build by default. You must
1321 specifically define BUILD_SUIDPERL to "true" for it to be build.
1322 Furthermore, we recommend that you remove /usr/bin/sperl* and
1323 /usr/bin/suidperl files from your system unless you have a
1324 specific use for it.
1327 Networking defaults have been tightened. Anybody upgrading
1328 /etc/defaults/rc.conf needs to add the following lines to
1329 /etc/rc.conf if they want to have the same setup
1330 afterwards (unless the variables already are set, of course):
1331 # Enable network daemons for user convenience.
1333 portmap_enable="YES"
1334 sendmail_enable="YES"
1337 If you have null_load="YES" in your /boot/loader.conf, you
1338 will need to change that to nullfs_load="YES".
1341 The "installkernel" target has changed slightly. Now even if
1342 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1343 it will install the MYKERNEL file (built with the buildkernel
1344 target) as /kernel rather than /MYKERNEL. Those who have
1345 updated their /boot/loader.conf files to point to /MYKERNEL
1346 should remove that entry or perform manual rename of /kernel
1350 If you use CVSUP or CTM to get CVS trees, AND you used to get
1351 the old crypto files from internat.freebsd.org AND you check
1352 out files from the CVS tree with the cvs command, please read
1353 http://people.freebsd.org/~imp/internat.txt
1354 for details on potential problems that you might have and how
1357 If you are merely a mirror, or don't answer yes to each of the
1358 clauses above, you needn't worry.
1361 /etc/security has been updated to print the inode number of
1362 setuid programs that have changed. You will see a large spike
1363 in the number of changed programs the first time when you run
1364 mergemaster to get a new /etc/security.
1367 /dev/random now has good entropy collection (from the keyboard
1368 and sysmouse drivers). Please ensure that either `options
1369 RANDOMDEV' is present in your kernel config file or that
1370 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1371 not have the /dev/random driver, OpenSSL (and consequently
1372 lots of crypto tools (like SSH)) will fail with strange
1373 errors. (see below, 20000624).
1375 FreeBSD-current is safe again to run Crypto.
1378 phk made the malloc default options AJ. This may slow things
1379 down and uncover other latent bugs in the code. If you need to
1380 run at full speed, you can disable this by doing the following:
1381 ln -s aj /etc/malloc.conf
1384 libftpio's version was accidentally bumped a few days ago. This
1385 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1386 before doing your next buildworld/installworld pair. It certainly
1387 won't hurt to remove it before the update procedure. It will
1388 break fetch until a new one is built, but ftp can be used in the
1392 The crypto packages have changed for the cvsup. This has been done
1393 in a backward compatible way, but the old packages will go away at
1394 some point in the future. Look at /usr/share/examples/cvsup for
1398 With the new sys/modules/sound/drivers/*, you will need to
1399 set SYSDIR until you do an installworld after July 7th.
1402 rc.shutdown and rc will now call the rc.d scripts with start
1403 or stop. This may cause some harmless warnings from older
1404 rc.d scripts that haven't been updated.
1407 The libfetch based version of fetch has gone into the tree.
1408 Minor problems may result on some of the less popular sites,
1409 which should be reported to des@freebsd.org.
1412 From approximately this date forward, one must have the crypto
1413 system installed in order to build the system and kernel.
1414 While not technically strictly true, one should treat it as
1415 required and grab the crypto bits. If you are grabbing CVS
1416 trees, src-all and cvs-crypto should be treated as if they
1417 were required. You should check with the latest collections
1418 to make sure that these haven't changed.
1421 Mark Murray just committed the first parts of a cleanup of
1422 /dev/zero, et al. This is also cleaning up /dev/random.
1423 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1424 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1425 until Mark can merge in the fixes to this work in progress.
1426 openssh and openssl should not be used to generate keys from this
1427 date to the completion of the work.
1429 If you must operate at this reduced level of security, add '
1430 options RANDOMDEV' to your kernel or modload the randomdev
1431 module. You may also need to copy a new MAKEDEV to /dev and
1432 recreate the random and urandom devices.
1435 The license on the softupdates is now a standard 2 clause
1436 BSD license. You may need to remove your symbolic links
1437 that used to be required when updating.
1440 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1441 the config file update procedure.
1442 http://people.freebsd.org/~imp/config-upd.html
1443 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1444 isn't buildable. However, you can generate a LINT file:
1445 cd /sys/<ARCH>/conf && make LINT
1448 Binutils 2.10 have hit the tree, or will shortly. As soon
1449 as they do, the problem noted in 20000522 will be resolved and
1450 that workaround will no longer be required.
1453 phk removed the compatibility creation of wd devices in the
1454 ad driver. If you haven't done so already, you must update
1455 your fstab, etc to use the ad devices instead of the wd
1458 In addition, you'll need to update your boot blocks to a
1459 more modern version, if you haven't already done so. Modern
1460 here means 4.0 release or newer (although older releases
1464 Peter took an axe to config(8). Be sure that you read his mail
1465 on the topic before even thinking about updating. You will
1466 need to create a /boot/device.hints or add a hints directive
1467 to your config file to compile them in statically. The format
1468 of the config file has changed as well. Please see GENERIC or
1469 NEWCARD for examples of the new format.
1471 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1472 says that it has been fixed, assume that must use the hints mechanism
1473 in the loader if you need to use a machine with very old ISA cards
1477 A new set of binutils went into the tree today. Anybody
1478 building a kernel after this point is advised that they need
1479 to rebuild their binutils (or better yet do a
1480 buildworld/installworld) before building a new kernel.
1482 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1483 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1484 is recommended that you don't set this option until the problem
1488 The ethernet drivers were all updated to clean up the BPF handling.
1491 The problems with boot blocks on the alphas have been corrected.
1492 This will require some care in updating alphas. A new libstand
1493 is requires for the boot blocks to build properly.
1496 Recompile all kld modules. Proper version dependency info
1500 Modules have been disconnected from the buildworld tree and
1501 connected to the kernel building instead.
1504 You may need to build gperf
1505 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1506 when upgrading from 4.0 -> current. The build system now uses
1507 an option only in -current.
1510 The method that we brand ELF binaries has changed to be more
1511 acceptable to the binutils maintainers. You will need to
1512 rebrand your ELF binaries that aren't native. One problem
1513 binary is the Linux ldconfig. After your make world, but
1514 before you reboot, you'll need to issue:
1515 brandelf -t Linux /compat/linux/sbin/ldconfig
1516 if you have Linux compatibility enabled on your machine.
1519 If you have really bad/marginal IDE drives, you may find they
1520 don't work well. Use pio mode instead. The easiest way to
1521 cope if you have a problem combination is to add:
1522 /sbin/sysctl hw.ata.ata_dma=0
1523 to the start of /etc/rc.conf.
1526 The ISA and PCI compatibility shims have been connected to the
1527 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1528 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1529 include the appropriate option in your kernel config. Drivers
1530 using the shims should be updated or they won't ship with
1531 5.0-RELEASE, targeted for 2001.
1534 We've entered the traditional post release dumping party.
1535 Large kernel changes are being committed and are in the
1536 works. It is important to keep the systems' klds and kernel
1537 in sync as kernel interfaces and structures are changing.
1538 Before reporting kernel panics, make sure that all modules
1539 that you are loading are up to date.
1542 If you are upgrading from an older version of FreeBSD, you
1543 need to update your boot blocks as well. 'disklabel -B ad0'
1544 will do the trick. This isn't critical until you remove your
1545 wd device entries in /dev, at which point your system will not
1549 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1550 to upgrade to 4.0 from 3.x.
1556 Avoid using make -j when upgrading. From time to time in the
1557 past there have been problems using -j with buildworld and/or
1558 installworld. This is especially true when upgrading between
1559 "distant" versions (eg one that cross a major release boundary
1560 or several minor releases, or when several months have passed
1561 on the -current branch).
1563 Sometimes, obscure build problems are the result of environment
1564 poisoning. This can happen because the make utility reads its
1565 environment when searching for values for global variables.
1566 To run your build attempts in an "environmental clean room",
1567 prefix all make commands with 'env -i '. See the env(1) manual
1568 page for more details.
1572 If you are updating from a prior version of FreeBSD (even one just
1573 a few days old), you should follow this procedure. With a
1574 /usr/obj tree with a fresh buildworld,
1575 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1576 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1578 To just build a kernel when you know that it won't mess you up
1579 --------------------------------------------------------------
1580 This assumes you are already running a 5.X system. Replace
1581 ${arch} with the architecture of your machine (e.g. "i386",
1582 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1584 cd src/sys/${arch}/conf
1585 config KERNEL_NAME_HERE
1586 cd ../compile/KERNEL_NAME_HERE
1591 If this fails, go to the "To build a kernel" section.
1593 To rebuild everything and install it on the current system.

1596 # is listed here if you are upgrading from a really old current.

1612 To cross-install current onto a separate partition
1613 --------------------------------------------------
1614 # In this approach we use a separate partition to hold
1615 # current's root, 'usr', and 'var' directories. A partition
1616 # holding "/", "/usr" and "/var" should be about 2GB in

1638 To upgrade in-place from 4.x-stable to current
1639 ----------------------------------------------
1640 # 5.x uses more space than 4.x. Also, the location of kernel
1641 # modules has changed. If you are installing 5.0 onto a 4.x
1642 # system, you'll need about 30MB of free disk space on your /
1643 # partition. If you have less than this, you may encounter difficult
1644 # to back out of problems with this procedure. If /tmp is on
1645 # the / partition, you may want to completely remove all its content
1646 # before upgrading, as this can be a common source of shortage of

1665 Make sure that you've read the UPDATING file to understand the
1666 tweaks to various things you need. At this point in the life
1667 cycle of current, things change often and you are on your own
1668 to cope. The defaults can also change, so please read ALL of
1669 the UPDATING entries.
1671 Also, if you are tracking -current, you must be subscribed to
1672 freebsd-current@freebsd.org. Make sure that before you update
1673 your sources that you have read and understood all the recent
1674 messages there. If in doubt, please track -stable which has
1675 much fewer pitfalls.
1677 [1] If you have third party modules, such as vmware, you
1678 should disable them at this point so they don't crash your
1681 [2] If you have legacy ISA devices, you may need to create
1682 your own device.hints to reflect your unique hardware
1685 [3] From the bootblocks, boot -s, and then do
1690 adjkerntz -i # if CMOS is wall time
1691 Also, when doing a major release upgrade, it is required that
1692 you boot into single user mode to do the installworld.
1693 For the 4.x -> 5.x upgrade, you will also see many messages about
1694 needing to recompile your userland. These are harmless and can
1695 be ignored while you proceed to the next step.
1697 [4] Note: This step is non-optional. Failure to do this step
1698 can result in a significant reduction in the functionality of the
1699 system. Attempting to do it by hand is not recommended and those
1700 that pursue this avenue should read this file carefully, as well
1701 as the archives of freebsd-current and freebsd-hackers mailing lists
1702 for potential gotchas.
1704 [5] Usually this step is a noop. However, from time to time
1705 you may need to do this if you get unknown user in the following
1706 step. It never hurts to do it all the time. You may need to
1707 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1708 install) after the buildworld before this step if you last updated
1709 from current before 20020224 or from -stable before 20020408.
1711 [6] 4.x boot loader can be used to boot a 5.x system, however
1712 it is difficult to do that at best. If you wish to try, then
1713 you should interrupt the boot and at the ok prompt type:
1715 ok boot /boot/kernel/kernel
1716 If this fails to work, you must install a new boot loader as
1719 [7] Before you upgrade, please make sure that you are not using
1720 compatibility slices. These are device names of the form, on i386
1721 and other architectures that use MBR slicing, /dev/ad0a without the
1722 actual slice name. Chances are excellent that these will break.
1723 You generally must update these entries to use the post FreeBSD
1724 2.x form of /dev/ad0s1a.
1726 [8] In order to have a kernel that can run the 4.x binaries
1727 needed to do an installworld, you must include the COMPAT_FREEBSD4
1728 option in your kernel. Failure to do so may leave you with a system
1729 that is hard to boot to recover.
1731 [9] When checking out sources, you must include the -P flag to have
1732 cvs prune empty directories. Also, if CPUTYPE is defined in your
1733 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1734 operator, so that buildworld can override the CPUTYPE if it needs to.
1735 In case you would like to avoid installing new packages of everything,
1736 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1737 compatibility libraries are built which should allow you to continue
1738 using your existing software for a while.
1740 [10] In order to create temporary files, /dev/random must be
1741 initialized by feeding data into it. /usr/src/etc/rc.d/preseedrandom
1745 This file contains a list, in reverse chronological order, of major
1746 breakages in tracking -current. Not all things will be listed here,
1747 and it only starts on March 15, 2000. Updating files can found in
1748 previous releases if your system is older than this.
