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

681 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
682 started out its life in the ISDN4BSD project as an offspring
683 from sys/net/if_spppsubr.c, which eventually got a life of its
684 own. All the accumulated features and bugfixes of the i4b
685 version have now been merged back into the base system's
686 version now. The only user-visible change resulting from this
687 is that i4b's sppp(4) interfaces are to be managed with
688 spppcontrol(8) again, since ispppcontrol(8) has been retired
689 as well. (There has never been rc file support for
690 ispppcontrol in -current, but only in -stable. That will be
691 reverted by the time the changes are MFCed.)
694 The fdc(4) driver has been updated and now automatically
695 recognizes media in `standard' formats (like 1440 KB and
696 720 KB for a 3.5" high-density drive) when accessing the
697 default device node (e. g. /dev/fd0). The old variety of
698 floppy device nodes /dev/fd*.* is no longer present by
699 default, devices can be created (in DEVFS) on demand. They
700 will need to be customized then for `odd' densities using
704 The bugs in procfs' debugging support code have been fixed,
705 and truss(1) now works again.
708 Daily security checks have been split out to use the periodic(8)
709 scripts. Some change in configuration may be necessary. Please
711 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
715 sos added VCD/SVCD support to ata driver and that needs the
716 kernel and burncd to be in sync.
719 The procfs pseudo-filesystem has now been converted to use the
720 pseudofs framework. If you have 'options PROCFS' in your
721 kernel config, you'll need to add 'options PSEUDOFS' if it's
724 This change temporarily breaks truss(1); use ktrace(1) instead
725 until the issue has been resolved.
728 A security hole in OpenSSH involving `UseLogin yes' has been
732 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
733 after this date. You need to do this only once.
736 Most of the awk issues have been resolved. Some rough
737 edges may be left, but for the most part things should be
738 back to "normal." For CURRENT's usual definition of "normal."
741 Awk has been upgraded to the one true awk from bell labs. Expect
742 choppy waves in the upgrade process.
745 The asr driver problem has been resolved.
748 Due to changes in other parts of the system, the asr driver
749 now causes the system to panic on boot. Do not use it pending
750 correction. Comment it out of any kernel config file that you
751 try to use from this date forward.
754 When crossbuilding, use TARGET=xxx where you used to use
755 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
756 unless you are changing both of them. To cross build pc98 on
757 an alpha, for example, you need to set TARGET=pc98 and
761 The kernel interface that burncd depends on has changed.
762 You must recompile both the kernel and userland applications
766 When crossbuilding, please set TARGET_ARCH rather than
767 MACHINE_ARCH to indicate the target. In the future, one will
768 set TARGET_MACHINE where you set MACHINE now. At the moment,
769 setting MACHINE alone for same MACHINE_ARCH machines works
770 (eg, you can build pc98 on an i386 machine and vice versa).
773 Some weird problems result from using ACPI on some machines.
774 To disable ACPI you can add
775 hint.acpi.0.disabled="1"
776 to /boot/loader.conf (or by putting set X=Y at the boot
779 Alternatively, you can remove it from /boot/kernel/acpi.ko
780 or use the MODULES_OVERRIDE function in your kernel config
781 file and not list acpi in that list.
784 The buildworld has been fixed. You may need to install
785 the 4.x compatibility libraries for some old binaries
786 to work. Add COMPAT4X=true to your /etc/make.conf to
787 get them installed on every installworld, or execute the
788 following to get them installed only once:
789 cd src/lib/compat/compat4x.<arch>
791 You will see ``__stdoutp undefined'' until you do this.
794 There's a bug in the world build process. The cross-tools
795 are build with the NEW headers, but the OLD libc.a. This
796 leads to all kinds of problems with the new libc. A temporary
798 CFLAGS="-O -pipe -D_OLD_STDIO"
799 before building world when upgrading from 4.x to current. This
800 can be removed afterwards.
802 A proper fix to the buildworld target is needed.
805 Peter has committed his new kthread nfs client/server code.
806 NFS may be unstable after this date.
809 KSE has hit the tree. Lots of things are now different in
810 the kernel. While a few problems were introduced in the
811 initial commit, most of the major ones have been found and
815 In OLDCARD, CardBus bridges appear to be stable. The work
816 arounds described in the 20010604 entry are now no longer
817 necessary and will be ignored. Most insert/remove problems
818 have been rectified around this date.
821 named now runs as user bind and group bind rather than as
822 root. If named_enable is set to YES in /etc/rc.conf, ensure
823 that user bind is available in /etc/passwd (using vipw(8))
824 and that group bind is available in /etc/group. Also make
825 sure that user or group bind has read (and not write)
826 permission for your name server configuration and that it
827 has read and write permission for your slave zone files and
830 If you wish to continue to run named as root (a less secure
831 alternative), add a line to /etc/rc.conf saying
836 The PAM libraries have had an API upgrade that is beyond
837 the ability of the shared library major number to handle.
838 It is manifested by PAM-using ports dumping core. The
839 solution is to rebuild those ports.
842 The kernel compile module has moved from src/sys/compile/FOO
843 to src/sys/${MACHINE}/compile/FOO.
846 The pccard modem issue from 20010613 has been corrected.
847 OLDCARD support is still a little weak in -current. slot 1 is
848 known not to work on some TI based cardbus bridges. Some
849 cardbus bridges do not properly detect insert/removal events.
850 IRQ configuration needs more safety belts.
853 Softupdates problems have been corrected.
856 Peter ripped out the linkerset support. You must, as always,
857 rerun config after you cvsup if you are using the traditional
858 kernel building methods.
861 pccard modems may not work with current after 20010604 date. Some
862 do, others result in panics. *MAKE*SURE* that you update your
863 config and /etc/rc.conf ala the 20010604 entry, or you will have
864 problems (this issue will be fixed, it just hasn't been yet).
867 SOFTUPDATES seem to be broken since the middle of May or so. Do not
868 use them in current. You can disable softupdates on all mounted
869 partitions, or remove SOFTUPDATES the kernel config file.
872 After Peter's commits to the hints code, people have been noticing
873 that certain devices are attached (or try to) twice. This is due
874 to having both static hints as well as a /boot/device.hints. To
875 work around this issue, please use only one or the other mechanism
876 until this bug is fixed.
878 Please note that a feature of config is that if you have config
879 file FOO and FOO.hints, it automatically adds FOO.hints to the
880 hints.c file, whether you want it to or not.
883 Locale names have changed to match other systems better.
886 pccard support for pci cards has been committed. You must change
887 your /etc/pccard.conf irq lines. It must match the irq used by
888 pcic device. Interrupt storms may result if you fail to do this.
889 Interrupt storms look a lot like a hang.
891 You must also install a new pccardd, otherwise you will get an
892 interrupt storm at card reset time (just after it tells you what
895 pccardd_flags="-I" is necessary for the time being. It tells pccardd
896 not to ask the kernel if the interrupt is really free or not before
897 using it. You can either change the /etc/pccard.conf irq lines to
898 match pcic, or add "-i X" to the pccardd_flags.
901 INSTALL=install -C is being deprecated. If you want to do this,
902 use COPY=-C instead. The former method will be supported for only
903 a limited time. If you see
905 install: warning: the -d and -C options may not be specified together
907 in your makeworld, then you need to migrate towards using
911 It appears that vm is now stable enough to use again. However,
912 there may be other problems, so caution is still urged. alpha
913 definitely is in bad shape.
916 Minor repo damage has happened. This may cause problems
917 with cvsup of ports. If you get errors, please see
918 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
919 at the bottom for details on a workaround. The error message
921 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
924 Vm and/or swapping are busted on -current. Please be patient.
927 pccard has had much reorganizational work done to it over
928 the past few days. Everything should still work, but if
929 not, please contact imp@freebsd.org.
932 ata ioctl changed. Make sure to recompile both kernel and
933 userland at the same time.
936 New ncurses imported.
939 DEVFS is now opt out, not opt in. Barring major problems, this
940 will be the only way to go starting July 1.
943 OpenSSH has been updated to 2.9. Some defaults are different,
944 including RhostsRSAAuthentication, which changes from yes to no.
947 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
950 Building perl was broken at 02:25:25 PDT.
953 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
954 go back in the water.
957 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
958 this date, but before the correction date.
961 old fsck and new kernel interactions appear to have been fixed.
964 fsck and the kernel were changed to handle some optimizations
965 to directory layout. This breaks backward compatibility.
966 Update only if you understand that you must not use the old
967 fsck with the new kernel ever.
970 fsck has changed the meaning of the pass column in /etc/fstab.
971 Please see the cvs commit to fsck.8 or the fsck.8 man page for
972 details. It is unclear if changes to /etc/fstab are necessary.
975 portmap had changed name to rpcbind for maximum POLA in your
976 current world. /etc/hosts.{allow,deny} needs changes. nfs and
977 other rpc based programs that rely on portmapper will not work
978 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
981 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
982 and ATA_ENABLE_TAGS are no longer kernel options. They have
983 been replaced by tunables. See ata.4 for details.
986 The fxp driver was converted to use miibus. If you compile
987 fxp into your kernel statically, you will need to add miibus.
990 The wi device now defaults to BSS (infrastructure) mode
994 /dev/urandom should be a symbolic link to /dev/random now.
995 Users of current not using DEVFS need to run MAKEDEV std.
996 ssh might not work if you don't.
999 The ed driver has been updated. It now allows mii attachments,
1000 which means that you must include the miibus in your kernel if
1001 you use the ed driver.
1004 The problems with libc have been corrected. It is now mostly
1005 safe to go back into the water.
1008 The size of FILE was changed. This breaks upgrading. If
1009 you must upgrade, be prepared for pain. It also breaks almost
1010 all binaries that you've compiled on -current. You are warned
1011 that before upgrading would be a good time to do a level 0
1012 dump of your system. No, really, I mean it this time.
1014 To get to the new system, you'll need to use the following
1015 workaround. Hopefully this can be sorted out so that we
1016 don't have to move this to the updating section.
1018 To get around the installworld problem, do:
1019 # cd /usr/src/usr.bin/sed
1023 If that doesn't work, then try:
1024 # make -k installworld
1028 DEVFS is now the default. If you use vinum, make sure that you
1029 do not include devfs in your kernel as problems result.
1032 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1033 Remove them from your config.
1036 ****************************** WARNING ******************************
1037 buildkernel has been changed slightly
1038 ****************************** WARNING ******************************
1039 KERNCONF replaces the variable KERNEL for buildkernel. You
1040 should update your scripts and make.conf accordingly.
1043 config has changed to allow DEV_FOO as a replacement for NFOO.
1044 This requires a new config to build correctly.
1047 The kernel option I386_CPU is now mutually exclusive with the
1048 other cpu types. If you have an i386 system, be sure that it
1049 only had this line. Remove it for all other configurations.
1052 Changes to the kernel require it and burncd be in sync.
1055 Everyone who has hw.sndunit set to something in
1056 /etc/sysctl.conf, it is now hw.snd.unit.
1059 ex and vi were broken by some changes to sys/queue.h. If you
1060 have a bad vi, you will see make buildworld fail with a core
1061 dump while building termcap. You can work around this problem
1062 by adding -k to your make buildworld. This will cause the
1063 build to complete and install a new vi. Once that's done, you
1064 can rebuild again without the -k to pick up anything that
1065 might have been ignored by the -k option.
1067 Others have suggested that you can just rebuild libc if your
1068 vi/ex is dynamically linked, but I've not received any reports
1072 There have been some changes to libcrypt in -current. The
1073 libscrypt/libdescrypt symlink silliness is gone and the installed
1074 libcrypt is fully functional. Be aware of this.
1077 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1078 now require the addition of flag 0x80000 to their config line
1079 in pccard.conf(5). This flag is not optional. These Linksys
1080 cards will not be recognized without it.
1083 Important new FreeBSD-version stuff: PAM support has been worked
1084 in, partially from the "Unix" OpenSSH version. This requires
1085 adding the following in pam.conf:
1087 sshd auth sufficient pam_skey.so
1088 sshd auth required pam_unix.so try_first_pass
1089 sshd session required pam_permit.so
1092 cvs updated to 1.11.
1095 The random device needs more entropy, so you need to make sure
1096 that you've run mergemaster to get a /etc/rc which will seed
1097 /dev/random. If you don't and the system hangs after ldconfig,
1098 then banging on the keyboard randomly until it unhangs is one

1119 The ports tree's new layout is in place. Be sure to update
1120 your entire ports tree, or you will have problems.
1123 The perl build procedure no longer installs miniperl, nor uses
1124 the installed miniperl. It is recommended that you delete
1128 This weekend the ports tree will be updated to a new layout.
1129 It will be in an inconsistent state until noted in the UPDATING
1130 file, or with asami-san's message to the relevant mailing
1131 lists. With this new layout, you'll need to update the whole
1132 tree for anything to work.
1135 There was a change in the passwd format. Need more information.
1138 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1139 place. Please update boot loader (not the boot blocks) at the
1140 same time as your kernel.
1143 The new pmtimer device is necessary for laptops. Failure to
1144 include the device will cause suspended laptops losing time
1145 when they resume. Include
1147 in your config file and
1148 hint.pmtimer.0.at="isa"
1149 to your /boot/device.hints file.
1152 The random device has been turned into a (pseudo-)device,
1153 rather than an option. The supplied kernel config files have
1154 been updated. You will need to do something similar in your
1155 own kernel config file.
1160 If you prefer to load the loadable module, you need to do
1164 The random device module has been renamed from randomdev.ko to
1165 random.ko. You will need to edit your /boot/loader.conf to
1166 reflect this if you load this module at boot time.
1167 The line should read:
1171 The SMPNG commit has happened. It should work, but if it
1172 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1173 to be a variety of minor issues. Please see 20000905 to make
1174 sure you don't have model loading problems which might at
1175 first blush appear related to SMP.
1178 nsswitch has been imported from NetBSD. Among other things,
1179 this means that /etc/host.conf is no longer used. See
1180 nsswitch.conf(5) instead. Note that at boot time rc.network
1181 will attempt to produce a new nsswitch.conf file for you if you
1182 don't have one, and you have host.conf.
1185 The ucred structure changed size. This breaks the interface
1186 that mountd uses. Trying to use an older mountd with a newer
1187 kernel guarantees a panic. This means that you need to use
1188 kernels newer than today only with matching mountd, but you
1189 needed to do that anyway with the boot loader changes.
1192 The boot loader has been updated. The new default kernel is
1193 now /boot/kernel/kernel.ko. The new default module location
1196 You *MUST* upgrade your boot loader and kernel at the same time.
1197 The easiest way to do this is to do the buildworld/buildkernel/
1198 installkernel/installworld dance.
1200 Furthermore, you are urged to delete your old /modules directory
1201 before booting the new kernel, since kldload will find stale
1202 modules in that directory instead of finding them in the correct
1203 path, /boot/kernel. The most common complaint that this cures
1204 is that the linux module crashes your machine after the update.
1206 if [ ! -d /boot/kernel.old ]; then
1207 mv /modules.old /boot/kernel.old
1208 chflags noschg /kernel.old
1209 mv /kernel.old /boot/kernel.old/kernel.ko
1210 chflags schg /boot/kernel.old/kernel.ko
1214 A new issue with the sendmail upgrade has come to light.
1215 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1216 incorrectly install the default aliases in /etc/mail rather than
1217 move the old one from /etc. So you'll need to manually move the
1218 file, create a symbolic link, remove the old /etc/aliases.db and
1219 run newaliases. For safety sake, you should stop sendmail
1220 while doing this and run the upgrade when locally sourced email
1221 is not likely to be generated.
1224 /boot/device.hints is now required for installkernel to
1225 succeed. You should copy GENERIC.hints for your architecture
1226 into /boot/device.hints. If and only if you compile hints
1227 into your kernel, then this file may be empty. Please note,
1228 if you have an empty or missing /boot/device.hints file and
1229 you neglected to compile hints into your kernel, no boot
1230 messages will appear after the boot loader tries to start the
1234 If you do NOT have ``options RANDOMDEV'' in your kernel and
1235 you DO want the random device then add randomdev_load="YES" to
1239 suidperl is now always built and installed on the system, but
1240 with permissions of 511. If you have applications that use
1241 this program, you are now required to add ENABLE_SUIDPERL=true
1242 to /etc/make.conf. If you forget to do this,
1243 chmod 4511 /usr/bin/suidperl
1244 will fix this until the next build.
1247 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1248 visible changes that may immediately affect your configuration
1250 - New default file locations from src/contrib/sendmail/cf/README
1251 - newaliases limited to root and trusted users
1252 - MSA port (587) turned on by default
1253 - New queue file naming system so can't go from 8.11 -> 8.9
1254 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1255 - FEATURE(`nullclient') is more full featured
1256 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1257 - mail.local FreeBSD-only -b option changed to -B
1258 - See src/contrib/sendmail/RELEASE_NOTES for more info
1261 suidperl (aka sperl) is no longer build by default. You must
1262 specifically define BUILD_SUIDPERL to "true" for it to be build.
1263 Furthermore, we recommend that you remove /usr/bin/sperl* and
1264 /usr/bin/suidperl files from your system unless you have a
1265 specific use for it.
1268 Networking defaults have been tightened. Anybody upgrading
1269 /etc/defaults/rc.conf needs to add the following lines to
1270 /etc/rc.conf if they want to have the same setup
1271 afterwards (unless the variables already are set, of course):
1272 # Enable network daemons for user convenience.
1274 portmap_enable="YES"
1275 sendmail_enable="YES"
1278 If you have null_load="YES" in your /boot/loader.conf, you
1279 will need to change that to nullfs_load="YES".
1282 The "installkernel" target has changed slightly. Now even if
1283 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1284 it will install the MYKERNEL file (built with the buildkernel
1285 target) as /kernel rather than /MYKERNEL. Those who have
1286 updated their /boot/loader.conf files to point to /MYKERNEL
1287 should remove that entry or perform manual rename of /kernel
1291 If you use CVSUP or CTM to get CVS trees, AND you used to get
1292 the old crypto files from internat.freebsd.org AND you check
1293 out files from the CVS tree with the cvs command, please read
1294 http://people.freebsd.org/~imp/internat.txt
1295 for details on potential problems that you might have and how
1298 If you are merely a mirror, or don't answer yes to each of the
1299 clauses above, you needn't worry.
1302 /etc/security has been updated to print the inode number of
1303 setuid programs that have changed. You will see a large spike
1304 in the number of changed programs the first time when you run
1305 mergemaster to get a new /etc/security.
1308 /dev/random now has good entropy collection (from the keyboard
1309 and sysmouse drivers). Please ensure that either `options
1310 RANDOMDEV' is present in your kernel config file or that
1311 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1312 not have the /dev/random driver, OpenSSL (and consequently
1313 lots of crypto tools (like SSH)) will fail with strange
1314 errors. (see below, 20000624).
1316 FreeBSD-current is safe again to run Crypto.
1319 phk made the malloc default options AJ. This may slow things
1320 down and uncover other latent bugs in the code. If you need to
1321 run at full speed, you can disable this by doing the following:
1322 ln -s aj /etc/malloc.conf
1325 libftpio's version was accidentally bumped a few days ago. This
1326 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1327 before doing your next buildworld/installworld pair. It certainly
1328 won't hurt to remove it before the update procedure. It will
1329 break fetch until a new one is built, but ftp can be used in the
1333 The crypto packages have changed for the cvsup. This has been done
1334 in a backward compatible way, but the old packages will go away at
1335 some point in the future. Look at /usr/share/examples/cvsup for
1339 With the new sys/modules/sound/drivers/*, you will need to
1340 set SYSDIR until you do an installworld after July 7th.
1343 rc.shutdown and rc will now call the rc.d scripts with start
1344 or stop. This may cause some harmless warnings from older
1345 rc.d scripts that haven't been updated.
1348 The libfetch based version of fetch has gone into the tree.
1349 Minor problems may result on some of the less popular sites,
1350 which should be reported to des@freebsd.org.
1353 From approximately this date forward, one must have the crypto
1354 system installed in order to build the system and kernel.
1355 While not technically strictly true, one should treat it as
1356 required and grab the crypto bits. If you are grabbing CVS
1357 trees, src-all and cvs-crypto should be treated as if they
1358 were required. You should check with the latest collections
1359 to make sure that these haven't changed.
1362 Mark Murray just committed the first parts of a cleanup of
1363 /dev/zero, et al. This is also cleaning up /dev/random.
1364 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1365 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1366 until Mark can merge in the fixes to this work in progress.
1367 openssh and openssl should not be used to generate keys from this
1368 date to the completion of the work.
1370 If you must operate at this reduced level of security, add '
1371 options RANDOMDEV' to your kernel or modload the randomdev
1372 module. You may also need to copy a new MAKEDEV to /dev and
1373 recreate the random and urandom devices.
1376 The license on the softupdates is now a standard 2 clause
1377 BSD license. You may need to remove your symbolic links
1378 that used to be required when updating.
1381 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1382 the config file update procedure.
1383 http://people.freebsd.org/~imp/config-upd.html
1384 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1385 isn't buildable. However, you can generate a LINT file:
1386 cd /sys/<ARCH>/conf && make LINT
1389 Binutils 2.10 have hit the tree, or will shortly. As soon
1390 as they do, the problem noted in 20000522 will be resolved and
1391 that workaround will no longer be required.
1394 phk removed the compatibility creation of wd devices in the
1395 ad driver. If you haven't done so already, you must update
1396 your fstab, etc to use the ad devices instead of the wd
1399 In addition, you'll need to update your boot blocks to a
1400 more modern version, if you haven't already done so. Modern
1401 here means 4.0 release or newer (although older releases
1405 Peter took an axe to config(8). Be sure that you read his mail
1406 on the topic before even thinking about updating. You will
1407 need to create a /boot/device.hints or add a hints directive
1408 to your config file to compile them in statically. The format
1409 of the config file has changed as well. Please see GENERIC or
1410 NEWCARD for examples of the new format.
1412 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1413 says that it has been fixed, assume that must use the hints mechanism
1414 in the loader if you need to use a machine with very old ISA cards
1418 A new set of binutils went into the tree today. Anybody
1419 building a kernel after this point is advised that they need
1420 to rebuild their binutils (or better yet do a
1421 buildworld/installworld) before building a new kernel.
1423 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1424 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1425 is recommended that you don't set this option until the problem
1429 The ethernet drivers were all updated to clean up the BPF handling.
1432 The problems with boot blocks on the alphas have been corrected.
1433 This will require some care in updating alphas. A new libstand
1434 is requires for the boot blocks to build properly.
1437 Recompile all kld modules. Proper version dependency info
1441 Modules have been disconnected from the buildworld tree and
1442 connected to the kernel building instead.
1445 You may need to build gperf
1446 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1447 when upgrading from 4.0 -> current. The build system now uses
1448 an option only in -current.
1451 The method that we brand ELF binaries has changed to be more
1452 acceptable to the binutils maintainers. You will need to
1453 rebrand your ELF binaries that aren't native. One problem
1454 binary is the Linux ldconfig. After your make world, but
1455 before you reboot, you'll need to issue:
1456 brandelf -t Linux /compat/linux/sbin/ldconfig
1457 if you have Linux compatibility enabled on your machine.
1460 If you have really bad/marginal IDE drives, you may find they
1461 don't work well. Use pio mode instead. The easiest way to
1462 cope if you have a problem combination is to add:
1463 /sbin/sysctl hw.ata.ata_dma=0
1464 to the start of /etc/rc.conf.
1467 The ISA and PCI compatibility shims have been connected to the
1468 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1469 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1470 include the appropriate option in your kernel config. Drivers
1471 using the shims should be updated or they won't ship with
1472 5.0-RELEASE, targeted for 2001.
1475 We've entered the traditional post release dumping party.
1476 Large kernel changes are being committed and are in the
1477 works. It is important to keep the systems' klds and kernel
1478 in sync as kernel interfaces and structures are changing.
1479 Before reporting kernel panics, make sure that all modules
1480 that you are loading are up to date.
1483 If you are upgrading from an older version of FreeBSD, you
1484 need to update your boot blocks as well. 'disklabel -B ad0'
1485 will do the trick. This isn't critical until you remove your
1486 wd device entries in /dev, at which point your system will not
1490 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1491 to upgrade to 4.0 from 3.x.
1497 Avoid using make -j when upgrading. From time to time in the
1498 past there have been problems using -j with buildworld and/or
1499 installworld. This is especially true when upgrading between
1500 "distant" versions (eg one that cross a major release boundary
1501 or several minor releases, or when several months have passed
1502 on the -current branch).
1504 Sometimes, obscure build problems are the result of environment
1505 poisoning. This can happen because the make utility reads its
1506 environment when searching for values for global variables.
1507 To run your build attempts in an "environmental clean room",
1508 prefix all make commands with 'env -i '. See the env(1) manual
1509 page for more details.
1513 If you are updating from a prior version of FreeBSD (even one just
1514 a few days old), you should follow this procedure. With a
1515 /usr/obj tree with a fresh buildworld,
1516 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1517 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1519 To just build a kernel when you know that it won't mess you up
1520 --------------------------------------------------------------
1521 This assumes you are already running a 5.X system. Replace
1522 ${arch} with the architecture of your machine (e.g. "i386",
1523 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1525 cd src/sys/${arch}/conf
1526 config KERNEL_NAME_HERE
1527 cd ../compile/KERNEL_NAME_HERE
1532 If this fails, go to the "To build a kernel" section.
1534 To rebuild everything and install it on the current system.
1535 -----------------------------------------------------------
1536 # Note: sometimes if you are running current you gotta do more than
1537 # is listed here if you are upgrading from a really old current.

1543 make installkernel KERNCONF=YOUR_KERNEL_HERE
1545 <reboot in single user> [3]
1546 /etc/rc.d/preseedrandom [10]
1553 To cross-install current onto a separate partition
1554 --------------------------------------------------
1555 # In this approach we use a separate partition to hold
1556 # current's root, 'usr', and 'var' directories. A partition
1557 # holding "/", "/usr" and "/var" should be about 2GB in
1560 <make sure you have good level 0 dumps>
1563 <maybe newfs current's root partition>
1564 <mount current's root partition on directory ${CURRENT_ROOT}>
1565 make installworld DESTDIR=${CURRENT_ROOT}
1566 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1567 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \
1568 ${CURRENT_ROOT}/boot/device.hints # as needed
1569 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1570 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1571 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
1572 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1573 <reboot into current>
1574 <do a "native" rebuild/install as described in the previous section>
1575 <maybe install compatibility libraries from /usr/src/lib/compat>
1579 To upgrade in-place from 4.x-stable to current
1580 ----------------------------------------------
1581 # 5.x uses more space than 4.x. Also, the location of kernel
1582 # modules has changed. If you are installing 5.0 onto a 4.x
1583 # system, you'll need about 30MB of free disk space on your /
1584 # partition. If you have less than this, you may encounter difficult
1585 # to back out of problems with this procedure. If /tmp is on
1586 # the / partition, you may want to completely remove all its content
1587 # before upgrading, as this can be a common source of shortage of
1590 <make sure you have good level 0 dumps>
1591 <maybe fix /etc/fstab> [7]
1593 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
1594 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
1595 make installkernel KERNCONF=YOUR_KERNEL_HERE
1596 cd sys/boot ; make STRIP="" install [6]
1598 <reboot in single user> [3]
1599 /usr/src/etc/rc.d/preseedrandom [10]
1601 rm -rf /usr/include/g++
1606 Make sure that you've read the UPDATING file to understand the
1607 tweaks to various things you need. At this point in the life
1608 cycle of current, things change often and you are on your own
1609 to cope. The defaults can also change, so please read ALL of
1610 the UPDATING entries.
1612 Also, if you are tracking -current, you must be subscribed to
1613 freebsd-current@freebsd.org. Make sure that before you update
1614 your sources that you have read and understood all the recent
1615 messages there. If in doubt, please track -stable which has
1616 much fewer pitfalls.
1618 [1] If you have third party modules, such as vmware, you
1619 should disable them at this point so they don't crash your
1622 [2] If you have legacy ISA devices, you may need to create
1623 your own device.hints to reflect your unique hardware
1626 [3] From the bootblocks, boot -s, and then do
1631 adjkerntz -i # if CMOS is wall time
1632 Also, when doing a major release upgrade, it is required that
1633 you boot into single user mode to do the installworld.
1634 For the 4.x -> 5.0 upgrade, you will also see many messages about
1635 needing to recompile your userland. These are harmless and can
1636 be ignored while you proceed to the next step.
1638 [4] Note: This step is non-optional. Failure to do this step
1639 can result in a significant reduction in the functionality of the
1640 system. Attempting to do it by hand is not recommended and those
1641 that pursue this avenue should read this file carefully, as well
1642 as the archives of freebsd-current and freebsd-hackers mailing lists
1643 for potential gotchas.
1645 [5] Usually this step is a noop. However, from time to time
1646 you may need to do this if you get unknown user in the following
1647 step. It never hurts to do it all the time. You may need to
1648 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1649 install) after the buildworld before this step if you last updated
1650 from current before 20020224 or from -stable before 20020408.
1652 [6] 4.x boot loader can be used to boot a 5.x system, however
1653 it is difficult to do that at best. If you wish to try, then
1654 you should interrupt the boot and at the ok prompt type:
1656 ok boot /boot/kernel/kernel
1657 If this fails to work, you must install a new boot loader as
1660 [7] Before you upgrade, please make sure that you are not using
1661 compatibility slices. These are device names of the form, on i386
1662 and other architectures that use MBR slicing, /dev/ad0a without the
1663 actual slice name. Chances are excellent that these will break.
1664 You generally must update these entries to use the post FreeBSD
1665 2.x form of /dev/ad0s1a.
1667 [8] In order to have a kernel that can run the 4.x binaries
1668 needed to do an installworld, you must include the COMPAT_FREEBSD4
1669 option in your kernel. Failure to do so may leave you with a system
1670 that is hard to boot to recover.
1672 [9] When checking out sources, you must include the -P flag to have
1673 cvs prune empty directories. Also, if CPUTYPE is defined in your
1674 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1675 operator, so that buildworld can override the CPUTYPE if it needs to.
1676 In case you would like to avoid installing new packages of everything,
1677 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1678 compatibility libraries are build which should allow you to continue
1679 using your existing software for a while.
1681 [10] In order to create temporary files, /dev/random must be
1682 initialized by feeding data into it. /etc/rc.d/preseedrandom
1686 This file contains a list, in reverse chronological order, of major
1687 breakages in tracking -current. Not all things will be listed here,
1688 and it only starts on March 15, 2000. Updating files can found in
1689 previous releases if your system is older than this.
