1 Updating Information for FreeBSD current users
3 This file is maintained by imp@village.org. Please send new entries
4 directly to him. See end of file for further details. For commonly
5 done items, please see the end of the file. Search for 'COMMON
9 The problems with libc have been corrected. It is now mostly
10 safe to go back into the water.
13 The size of FILE was changed. This breaks upgrading. If
14 you must upgrade, be prepared for pain. It also breaks almost
15 all binaries that you've compiled on -current. You are warned
16 that before upgrading would be a good time to do a level 0
17 dump of your system. No, really, I mean it this time.
19 To get to the new system, you'll need to use the following
20 workaround. Hopefully this can be sorted out so that we
21 don't have to move this to the updating section.
23 To get around the installworld problem, do:
24 # cd /usr/src/usr.bin/sed
28 If that doesn't work, then try:
29 # make -k installworld
33 DEVFS is now the default. If you use vinum, make sure that you
34 do not include devfs in your kernel as problems result.
37 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
38 Remove them from your config.
41 ****************************** WARNING ******************************
42 buildkernel has been changed slightly
43 ****************************** WARNING ******************************
44 KERNCONF replaces the variable KERNEL for buildkernel. You
45 should update your scripts and make.conf accordingly.
48 config has changed to allow DEV_FOO as a replacement for NFOO.
49 This requires a new config to build correctly.
52 The kerrnel option I386_CPU is now mutually exclusive with the
53 other cpu types. If you have an i386 system, be sure that it
54 only had this line. Remove it for all other configurations.
57 Changes to the kernel require it and burncd be in sync.
60 Everyone who has hw.sndunit set to something in
61 /etc/sysctl.conf, it is now hw.snd.unit.
64 ex and vi were broken by some changes to sys/queue.h. If you
65 have a bad vi, you will see make buildworld fail with a core
66 dump while building termcap. You can work around this problem
67 by adding -k to your make buildworld. This will cause the
68 build to complete and install a new vi. Once that's done, you
69 can rebuild again without the -k to pick up anything that
70 might have been ignored by the -k option.
72 Others have suggested that you can just rebuild libc if your
73 vi/ex is dynamically linked, but I've not received any reports
77 There have been some changes to libcrypt in -current. The
78 libscrypt/libdescrypt symlink sillyness is gone and the installed
79 libcrypt is fully functional. Be aware of this.
82 Linksys Fast Ethernet PCCARD cards supported by the ed driver
83 now require the addition of flag 0x80000 to their config line
84 in pccard.conf(5). This flag is not optional. These Linksys
85 cards will not be recognized without it.
88 Important new FreeBSD-version stuff: PAM support has been worked
89 in, partially from the "Unix" OpenSSH version. This requires
90 adding the following in pam.conf:
92 sshd auth sufficient pam_skey.so
93 sshd auth required pam_unix.so try_first_pass
94 sshd session required pam_permit.so
100 The random device needs more entropy, so you need to make sure
101 that you've run mergemaster to get a /etc/rc which will seed
102 /dev/random. If you don't and the system hangs after ldconfig,
103 then banging on the keyboard randomly until it unhangs is one
107 ****************************** WARNING ******************************
108 Sendmail has been updated.
109 ****************************** WARNING ******************************
110 o mail.local(8) is no longer installed as a set-user-id binary.
111 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL
113 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY
115 o Now using sendmail's version of vacation(1).
116 o The sendmail cf building tools (contrib/sendmail/cf) are installed
117 in /usr/share/sendmail/cf.
118 o sendmail.cw changed to local-host-names
120 More details can be found at
121 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010
124 The ports tree's new layout is in place. Be sure to update
125 your entire ports tree, or you will have problems.
128 The perl build procedure no longer installs miniperl, nor uses
129 the installed miniperl. It is recommended that you delete
133 This weekend the ports tree will be updated to a new layout.
134 It will be in an inconsistent state until noted in the UPDATING
135 file, or with asami-san's message to the relevant mailing
136 lists. With this new layout, you'll need to update the whole
137 tree for anything to work.
140 There was a change in the passwd format. Need more information.
143 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
144 place. Please update boot loader (not the boot blocks) at the
145 same time as your kernel.
148 The new pmtimer device is necessary for laptops. Failure to
149 include the device will cause suspended laptops losing time
150 when they resume. Include
152 in your config file and
153 hint.pmtimer.0.at="isa"
154 to your /boot/device.hints file.
157 The random device has been turned into a (pseudo-)device,
158 rather than an option. The supplied kernel config files have
159 been updated. You will need to do something similar in your
160 own kernel config file.
165 If you prefer to load the loadable module, you need to do
169 The random device module has been renamed from randomdev.ko to
170 random.ko. You will need to edit your /boot/loader.conf to
171 reflect this if you load this module at boot time.
172 The line should read:
176 The SMPNG commit has happened. It should work, but if it
177 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
178 to be a variety of minor issues. Please see 20000905 to make
179 sure you don't have model loading problems which might at
180 first blush appear related to SMP.
183 nsswitch has been imported from NetBSD. Among other things,
184 this means that /etc/host.conf is no longer used. See
185 nsswitch.conf(5) instead. Note that at boot time rc.network
186 will attempt to produce a new nsswitch.conf file for you if you
187 don't have one, and you have host.conf.
190 The ucred structure changed size. This breaks the interface
191 that mountd uses. Trying to use an older mountd with a newer
192 kernel guarantees a panic. This means that you need to use
193 kernels newer than today only with matching mountd, but you
194 needed to do that anyway with the boot loader changes.
197 The boot loader has been updated. The new default kernel is
198 now /boot/kernel/kernel.ko. The new default module location
201 You *MUST* upgrade your boot loader and kernel at the same time.
202 The easiest way to do this is to do the buildworld/buildkernel/
203 installkernel/installworld dance.
205 Furthermore, you are urged to delete your old /modules directory
206 before booting the new kernel, since kldload will find stale
207 modules in that directory instead of finding them in the correct
208 path, /boot/kernel. The most common complaint that this cures
209 is that the linux module crashes your machine after the update.
211 if [ ! -d /boot/kernel.old ]; then
212 mv /modules.old /boot/kernel.old
213 chflags noschg /kernel.old
214 mv /kernel.old /boot/kernel.old/kernel.ko
215 chflags schg /boot/kernel.old/kernel.ko
219 A new issue with the sendmail upgrade has come to light.
220 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
221 incorrectly install the default aliases in /etc/mail rather than
222 move the old one from /etc. So you'll need to manually move the
223 file, create a symbolic link, remove the old /etc/aliases.db and
224 run newaliases. For safety sake, you should stop sendmail
225 while doing this and run the upgrade when locally sourced email
226 is not likely to be generated.
229 /boot/device.hints is now required for installkernel to
230 succeed. You should copy GENERIC.hints for your architecture
231 into /boot/device.hints. If and only if you compile hints
232 into your kernel, then this file may be empty. Please note,
233 if you have an empty or missing /boot/device.hints file and
234 you neglected to compile hints into your kernel, no boot
235 messages will appear after the boot loader tries to start the
239 If you do NOT have ``options RANDOMDEV'' in your kernel and
240 you DO want the random device then add randomdev_load="YES" to
244 suidperl is now always built and installed on the system, but
245 with permissions of 511. If you have applications that use
246 this program, you are now required to add ENABLE_SUIDPERL=true
247 to /etc/make.conf. If you forget to do this,
248 chmod 4511 /usr/bin/suidperl
249 will fix this until the next build.
252 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
253 visible changes that may immediately affect your configuration
255 - New default file locations from src/contrib/sendmail/cf/README
256 - newaliases limited to root and trusted users
257 - MSA port (587) turned on by default
258 - New queue file naming system so can't go from 8.11 -> 8.9
259 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
260 - FEATURE(`nullclient') is more full featured
261 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
262 - mail.local FreeBSD-only -b option changed to -B
263 - See src/contrib/sendmail/RELEASE_NOTES for more info
266 suidperl (aka sperl) is no longer build by default. You must
267 specifically define BUILD_SUIDPERL to "true" for it to be build.
268 Furthermore, we recommend that you remove /usr/bin/sperl* and
269 /usr/bin/suidperl files from your system unless you have a
273 Networking defaults have been tightened. Anybody upgrading
274 /etc/defaults/rc.conf needs to add the following lines to
275 /etc/rc.conf if they want to have the same setup
276 afterwards (unless the variables already are set, of course):
277 # Enable network daemons for user convenience.
280 sendmail_enable="YES"
283 If you have null_load="YES" in your /boot/loader.conf, you
284 will need to change that to nullfs_load="YES".
287 The "installkernel" target has changed slightly. Now even if
288 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
289 it will install the MYKERNEL file (built with the buildkernel
290 target) as /kernel rather than /MYKERNEL. Those who have
291 updated their /boot/loader.conf files to point to /MYKERNEL
292 should remove that entry or perform manual rename of /kernel
296 If you use CVSUP or CTM to get CVS trees, AND you used to get
297 the old crypto files from internat.freebsd.org AND you check
298 out files from the CVS tree with the cvs command, please read
299 http://people.freebsd.org/~imp/internat.txt
300 for details on potential problems that you might have and how
303 If you are merely a mirror, or don't answer yes to each of the
304 clauses above, you needn't worry.
307 /etc/security has been updated to print the inode number of
308 setuid programs that have changed. You will see a large spike
309 in the number of changed programs the first time when you run
310 mergemaster to get a new /etc/security.
313 /dev/random now has good entropy collection (from the keyboard
314 and sysmouse drivers). Please ensure that either `options
315 RANDOMDEV' is present in your kernel config file or that
316 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
317 not have the /dev/random driver, OpenSSL (and consequently
318 lots of crypto tools (like SSH)) will fail with strange
319 errors. (see below, 20000624).
321 FreeBSD-current is safe again to run Crypto.
324 phk made the malloc default options AJ. This may slow things
325 down and uncover other latent bugs in the code. If you need to
326 run at full speed, you can disable this by doing the following:
327 ln -s aj /etc/malloc.conf
330 libftpio's version was accidentally bumped a few days ago. This
331 has been corrected. You may need to remove /usr/lib/libftpio.so.6
332 before doing your next buildworld/installworld pair. It certainly
333 won't hurt to remove it before the update procedure. It will
334 break fetch until a new one is built, but ftp can be used in the
338 The crypto packages have changed for the cvsup. This has been done
339 in a backward compatible way, but the old packages will go away at
340 some point in the future. Look at /usr/share/examples/cvsup for
344 With the new sys/modules/sound/drivers/*, you will need to
345 set SYSDIR until you do an installworld after July 7th.
348 rc.shutdown and rc will now call the rc.d scripts with start
349 or stop. This may cause some harmless warnings from older
350 rc.d scripts that haven't been updated.
353 The libfetch based version of fetch has gone into the tree.
354 Minor problems may result on some of the less popular sites,
355 which should be reported to des@freebsd.org.
358 From approximately this date forward, one must have the crypto
359 system installed in order to build the system and kernel.
360 While not technically strictly true, one should treat it as
361 required and grab the crypto bits. If you are grabbing CVS
362 trees, src-all and cvs-crypto should be treated as if they
363 were required. You should check with the latest collections
364 to make sure that these haven't changed.
367 Mark Murray just committed the first parts of a cleanup of
368 /dev/zero, et al. This is also cleaning up /dev/random.
369 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
370 -CURRENT FROM THIS POINT FORWARD for cryptographic services
371 until Mark can merge in the fixes to this work in progress.
372 openssh and openssl should not be used to generate keys from this
373 date to the completion of the work.
375 If you must operate at this reduced level of security, add '
376 options RANDOMDEV' to your kernel or modload the randomdev
377 module. You may also need to copy a new MAKEDEV to /dev and
378 recreate the random and urandom devices.
381 The license on the softupdates is now a standard 2 clause
382 BSD license. You may need to remove your symbolic links
383 that used to be required when updating.
386 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
387 the config file update procedure.
388 http://people.freebsd.org/~imp/config-upd.html
389 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
390 isn't buildable. However, you can generate a LINT file.
393 Binutils 2.10 have hit the tree, or will shortly. As soon
394 as they do, the problem noted in 20000522 will be resolved and
395 that workaround will no longer be required.
398 phk removed the compatibility creation of wd devices in the
399 ad driver. If you haven't done so already, you must update
400 your fstab, etc to use the ad devices instead of the wd
403 In addition, you'll need to update your boot blocks to a
404 more modern version, if you haven't already done so. Modern
405 here means 4.0 release or newer (although older releases
409 Peter took an axe to config(8). Be sure that you read his mail
410 on the topic before even thinking about updating. You will
411 need to create a /boot/device.hints or add a hints directive
412 to your config file to compile them in statically. The format
413 of the config file has changed as well. Please see GENERIC or
414 NEWCARD for examples of the new format.
417 A new set of binutils went into the tree today. Anybody
418 building a kernel after this point is advised that they need
419 to rebuild their binutils (or better yet do a
420 buildworld/installworld) before building a new kernel.
422 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
423 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
424 is recommended that you don't set this option until the problem
428 The ethernet drivers were all updated to clean up the BPF handling.
431 The problems with boot blocks on the alphas have been corrected.
432 This will require some care in updating alphas. A new libstand
433 is requires for the boot blocks to build properly.
436 Recompile all kld modules. Proper version dependency info
440 Modules have been disconnected from the buildworld tree and
441 connected to the kernel building instead.
444 You may need to build gperf
445 cd /usr/src/gnu/usr.bin/gperf && make depend all install
446 when upgrading from 4.0 -> current. The build system now uses
447 an option only in -current.
450 The method that we brand ELF binaries has changed to be more
451 acceptable to the binutils maintainers. You will need to
452 rebrand your ELF binaries that aren't native. One problem
453 binary is the Linux ldconfig. After your make world, but
454 before you reboot, you'll need to issue:
455 brandelf -t Linux /compat/linux/sbin/ldconfig
456 if you have Linux compatibility enabled on your machine.
459 If you have really bad/marginal IDE drives, you may find they
460 don't work well. Use pio mode instead. The easiest way to
461 cope if you have a problem combination is to add:
462 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio
463 to the start of /etc/rc.conf.
466 The ISA and PCI compatibility shims have been connected to the
467 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
468 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
469 include the appropriate option in your kernel config. Drivers
470 using the shims should be updated or they won't ship with
471 5.0-RELEASE, targeted for 2001.
474 We've entered the traditional post release dumping party.
475 Large kernel changes are being committed and are in the
476 works. It is important to keep the systems' klds and kernel
477 in sync as kernel interfaces and structures are changing.
478 Before reporting kernel panics, make sure that all modules
479 that you are loading are up to date.
482 If you are upgrading from an older version of FreeBSD, you
483 need to update your boot blocks as well. 'disklabel -B ad0'
484 will do the trick. This isn't critical until you remove your
485 wd device entries in /dev, at which point your system will not
489 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
490 to upgrade to 4.0 from 3.x.
496 Avoid using make -j when upgrading. From time to time in the
497 past there have been problems using -j with buildworld and/or
498 installworld. This is especially true when upgrading between
499 "distant" versions (eg one that cross a major release boundary
500 or several minor releases, or when several months have passed
501 on the -current branch).
505 If you are updating from a prior version of FreeBSD (even one just
506 a few days old), you should follow this procedure. With a
507 /usr/obj tree with a fresh buildworld,
508 make buildkernel KERNCONF=YOUR_KERNEL_HERE
509 make installkernel KERNCONF=YOUR_KERNEL_HERE
511 To just build a kernel when you know that it won't mess you up
512 --------------------------------------------------------------
513 cd src/sys/{i386,alpha}/conf
514 config KERNEL_NAME_HERE [1]
515 cd ../../compile/KERNEL_NAME_HERE
520 [1] If in doubt, -r might help here.
522 If this fails, go to the "To build a kernel" section.
524 To rebuild everything and install it on the current system.
525 -----------------------------------------------------------
527 Build a new kernel, see above.
529 To upgrade from 4.x-stable to current
530 -------------------------------------
532 make buildkernel KERNCONF=YOUR_KERNEL_HERE
533 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2]
534 make installkernel KERNCONF=YOUR_KERNEL_HERE
540 Make sure that you've read the UPDATING file to understand the
541 tweaks to various things you need. At this point in the life
542 cycle of current, things change often and you are on your own
543 to cope. The defaults can also change, so please read ALL of
544 the UPDATING entries.
546 Also, if you are tracking -current, you must be subscribed to
547 freebsd-current@freebsd.org. Make sure that before you update
548 your sources that you have read and understood all the recent
549 messages there. If in doubt, please track -stable which has

553 should disable them at this point so they don't crash your
556 [2] If you have legacy ISA devices, you may need to create
557 your own device.hints to reflect your unique hardware
562 This file contains a list, in reverse chronological order, of major
563 breakages in tracking -current. Not all things will be listed here,
564 and it only starts on March 15, 2000. Updating files can found in
565 previous releases if your system is older than this.
567 Please filter your entries through Warner Losh (imp@village.org) so
568 that the style, formatting, etc of this file can be maintained.
