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

692 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
693 started out its life in the ISDN4BSD project as an offspring
694 from sys/net/if_spppsubr.c, which eventually got a life of its
695 own. All the accumulated features and bug fixes of the i4b
696 version have now been merged back into the base system's
697 version now. The only user-visible change resulting from this
698 is that i4b's sppp(4) interfaces are to be managed with
699 spppcontrol(8) again, since ispppcontrol(8) has been retired
700 as well. (There has never been rc file support for
701 ispppcontrol in -current, but only in -stable. That will be
702 reverted by the time the changes are MFCed.)
705 The fdc(4) driver has been updated and now automatically
706 recognizes media in `standard' formats (like 1440 KB and
707 720 KB for a 3.5" high-density drive) when accessing the
708 default device node (e. g. /dev/fd0). The old variety of
709 floppy device nodes /dev/fd*.* is no longer present by
710 default, devices can be created (in DEVFS) on demand. They
711 will need to be customized then for `odd' densities using
715 The bugs in procfs' debugging support code have been fixed,
716 and truss(1) now works again.
719 Daily security checks have been split out to use the periodic(8)
720 scripts. Some change in configuration may be necessary. Please
722 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
726 sos added VCD/SVCD support to ata driver and that needs the
727 kernel and burncd to be in sync.
730 The procfs pseudo-filesystem has now been converted to use the
731 pseudofs framework. If you have 'options PROCFS' in your
732 kernel config, you'll need to add 'options PSEUDOFS' if it's
735 This change temporarily breaks truss(1); use ktrace(1) instead
736 until the issue has been resolved.
739 A security hole in OpenSSH involving `UseLogin yes' has been
743 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
744 after this date. You need to do this only once.
747 Most of the awk issues have been resolved. Some rough
748 edges may be left, but for the most part things should be
749 back to "normal." For CURRENT's usual definition of "normal."
752 Awk has been upgraded to the one true awk from bell labs. Expect
753 choppy waves in the upgrade process.
756 The asr driver problem has been resolved.
759 Due to changes in other parts of the system, the asr driver
760 now causes the system to panic on boot. Do not use it pending
761 correction. Comment it out of any kernel config file that you
762 try to use from this date forward.
765 When crossbuilding, use TARGET=xxx where you used to use
766 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
767 unless you are changing both of them. To cross build pc98 on
768 an alpha, for example, you need to set TARGET=pc98 and
772 The kernel interface that burncd depends on has changed.
773 You must recompile both the kernel and userland applications
777 When crossbuilding, please set TARGET_ARCH rather than
778 MACHINE_ARCH to indicate the target. In the future, one will
779 set TARGET_MACHINE where you set MACHINE now. At the moment,
780 setting MACHINE alone for same MACHINE_ARCH machines works
781 (eg, you can build pc98 on an i386 machine and vice versa).
784 Some weird problems result from using ACPI on some machines.
785 To disable ACPI you can add
786 hint.acpi.0.disabled="1"
787 to /boot/loader.conf (or by putting set X=Y at the boot
790 Alternatively, you can remove it from /boot/kernel/acpi.ko
791 or use the MODULES_OVERRIDE function in your kernel config
792 file and not list acpi in that list.
795 The buildworld has been fixed. You may need to install
796 the 4.x compatibility libraries for some old binaries
797 to work. Add COMPAT4X=true to your /etc/make.conf to
798 get them installed on every installworld, or execute the
799 following to get them installed only once:
800 cd src/lib/compat/compat4x.<arch>
802 You will see ``__stdoutp undefined'' until you do this.
805 There's a bug in the world build process. The cross-tools
806 are build with the NEW headers, but the OLD libc.a. This
807 leads to all kinds of problems with the new libc. A temporary
809 CFLAGS="-O -pipe -D_OLD_STDIO"
810 before building world when upgrading from 4.x to current. This
811 can be removed afterwards.
813 A proper fix to the buildworld target is needed.
816 Peter has committed his new kthread nfs client/server code.
817 NFS may be unstable after this date.
820 KSE has hit the tree. Lots of things are now different in
821 the kernel. While a few problems were introduced in the
822 initial commit, most of the major ones have been found and
826 In OLDCARD, CardBus bridges appear to be stable. The work
827 arounds described in the 20010604 entry are now no longer
828 necessary and will be ignored. Most insert/remove problems
829 have been rectified around this date.
832 named now runs as user bind and group bind rather than as
833 root. If named_enable is set to YES in /etc/rc.conf, ensure
834 that user bind is available in /etc/passwd (using vipw(8))
835 and that group bind is available in /etc/group. Also make
836 sure that user or group bind has read (and not write)
837 permission for your name server configuration and that it
838 has read and write permission for your slave zone files and
841 If you wish to continue to run named as root (a less secure
842 alternative), add a line to /etc/rc.conf saying
847 The PAM libraries have had an API upgrade that is beyond
848 the ability of the shared library major number to handle.
849 It is manifested by PAM-using ports dumping core. The
850 solution is to rebuild those ports.
853 The kernel compile module has moved from src/sys/compile/FOO
854 to src/sys/${MACHINE}/compile/FOO.
857 The pccard modem issue from 20010613 has been corrected.
858 OLDCARD support is still a little weak in -current. slot 1 is
859 known not to work on some TI based cardbus bridges. Some
860 cardbus bridges do not properly detect insert/removal events.
861 IRQ configuration needs more safety belts.
864 Softupdates problems have been corrected.
867 Peter ripped out the linkerset support. You must, as always,
868 rerun config after you cvsup if you are using the traditional
869 kernel building methods.
872 pccard modems may not work with current after 20010604 date. Some
873 do, others result in panics. *MAKE*SURE* that you update your
874 config and /etc/rc.conf ala the 20010604 entry, or you will have
875 problems (this issue will be fixed, it just hasn't been yet).
878 SOFTUPDATES seem to be broken since the middle of May or so. Do not
879 use them in current. You can disable softupdates on all mounted
880 partitions, or remove SOFTUPDATES the kernel config file.
883 After Peter's commits to the hints code, people have been noticing
884 that certain devices are attached (or try to) twice. This is due
885 to having both static hints as well as a /boot/device.hints. To
886 work around this issue, please use only one or the other mechanism
887 until this bug is fixed.
889 Please note that a feature of config is that if you have config
890 file FOO and FOO.hints, it automatically adds FOO.hints to the
891 hints.c file, whether you want it to or not.
894 Locale names have changed to match other systems better.
897 pccard support for pci cards has been committed. You must change
898 your /etc/pccard.conf irq lines. It must match the irq used by
899 pcic device. Interrupt storms may result if you fail to do this.
900 Interrupt storms look a lot like a hang.
902 You must also install a new pccardd, otherwise you will get an
903 interrupt storm at card reset time (just after it tells you what
906 pccardd_flags="-I" is necessary for the time being. It tells pccardd
907 not to ask the kernel if the interrupt is really free or not before
908 using it. You can either change the /etc/pccard.conf irq lines to
909 match pcic, or add "-i X" to the pccardd_flags.
912 INSTALL=install -C is being deprecated. If you want to do this,
913 use COPY=-C instead. The former method will be supported for only
914 a limited time. If you see
916 install: warning: the -d and -C options may not be specified together
918 in your makeworld, then you need to migrate towards using
922 It appears that vm is now stable enough to use again. However,
923 there may be other problems, so caution is still urged. alpha
924 definitely is in bad shape.
927 Minor repo damage has happened. This may cause problems
928 with cvsup of ports. If you get errors, please see
929 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
930 at the bottom for details on a workaround. The error message
932 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
935 Vm and/or swapping are busted on -current. Please be patient.
938 pccard has had much reorganizational work done to it over
939 the past few days. Everything should still work, but if
940 not, please contact imp@freebsd.org.
943 ata ioctl changed. Make sure to recompile both kernel and
944 userland at the same time.
947 New ncurses imported.
950 DEVFS is now opt out, not opt in. Barring major problems, this
951 will be the only way to go starting July 1.
954 OpenSSH has been updated to 2.9. Some defaults are different,
955 including RhostsRSAAuthentication, which changes from yes to no.
958 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
961 Building perl was broken at 02:25:25 PDT.
964 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
965 go back in the water.
968 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
969 this date, but before the correction date.
972 old fsck and new kernel interactions appear to have been fixed.
975 fsck and the kernel were changed to handle some optimizations
976 to directory layout. This breaks backward compatibility.
977 Update only if you understand that you must not use the old
978 fsck with the new kernel ever.
981 fsck has changed the meaning of the pass column in /etc/fstab.
982 Please see the cvs commit to fsck.8 or the fsck.8 man page for
983 details. It is unclear if changes to /etc/fstab are necessary.
986 portmap had changed name to rpcbind for maximum POLA in your
987 current world. /etc/hosts.{allow,deny} needs changes. nfs and
988 other rpc based programs that rely on portmapper will not work
989 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
992 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
993 and ATA_ENABLE_TAGS are no longer kernel options. They have
994 been replaced by tunables. See ata.4 for details.
997 The fxp driver was converted to use miibus. If you compile
998 fxp into your kernel statically, you will need to add miibus.
1001 The wi device now defaults to BSS (infrastructure) mode
1005 /dev/urandom should be a symbolic link to /dev/random now.
1006 Users of current not using DEVFS need to run MAKEDEV std.
1007 ssh might not work if you don't.
1010 The ed driver has been updated. It now allows mii attachments,
1011 which means that you must include the miibus in your kernel if
1012 you use the ed driver.
1015 The problems with libc have been corrected. It is now mostly
1016 safe to go back into the water.
1019 The size of FILE was changed. This breaks upgrading. If
1020 you must upgrade, be prepared for pain. It also breaks almost
1021 all binaries that you've compiled on -current. You are warned
1022 that before upgrading would be a good time to do a level 0
1023 dump of your system. No, really, I mean it this time.
1025 To get to the new system, you'll need to use the following
1026 workaround. Hopefully this can be sorted out so that we
1027 don't have to move this to the updating section.
1029 To get around the installworld problem, do:
1030 # cd /usr/src/usr.bin/sed
1034 If that doesn't work, then try:
1035 # make -k installworld
1039 DEVFS is now the default. If you use vinum, make sure that you
1040 do not include devfs in your kernel as problems result.
1043 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1044 Remove them from your config.
1047 ****************************** WARNING ******************************
1048 buildkernel has been changed slightly
1049 ****************************** WARNING ******************************
1050 KERNCONF replaces the variable KERNEL for buildkernel. You
1051 should update your scripts and make.conf accordingly.
1054 config has changed to allow DEV_FOO as a replacement for NFOO.
1055 This requires a new config to build correctly.
1058 The kernel option I386_CPU is now mutually exclusive with the
1059 other cpu types. If you have an i386 system, be sure that it
1060 only had this line. Remove it for all other configurations.
1063 Changes to the kernel require it and burncd be in sync.
1066 Everyone who has hw.sndunit set to something in
1067 /etc/sysctl.conf, it is now hw.snd.unit.
1070 ex and vi were broken by some changes to sys/queue.h. If you
1071 have a bad vi, you will see make buildworld fail with a core
1072 dump while building termcap. You can work around this problem
1073 by adding -k to your make buildworld. This will cause the
1074 build to complete and install a new vi. Once that's done, you
1075 can rebuild again without the -k to pick up anything that
1076 might have been ignored by the -k option.
1078 Others have suggested that you can just rebuild libc if your
1079 vi/ex is dynamically linked, but I've not received any reports
1083 There have been some changes to libcrypt in -current. The
1084 libscrypt/libdescrypt symlink silliness is gone and the installed
1085 libcrypt is fully functional. Be aware of this.
1088 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1089 now require the addition of flag 0x80000 to their config line
1090 in pccard.conf(5). This flag is not optional. These Linksys
1091 cards will not be recognized without it.
1094 Important new FreeBSD-version stuff: PAM support has been worked
1095 in, partially from the "Unix" OpenSSH version. This requires
1096 adding the following in pam.conf:
1098 sshd auth sufficient pam_skey.so
1099 sshd auth required pam_unix.so try_first_pass
1100 sshd session required pam_permit.so
1103 cvs updated to 1.11.
1106 The random device needs more entropy, so you need to make sure
1107 that you've run mergemaster to get a /etc/rc which will seed
1108 /dev/random. If you don't and the system hangs after ldconfig,
1109 then banging on the keyboard randomly until it unhangs is one

1130 The ports tree's new layout is in place. Be sure to update
1131 your entire ports tree, or you will have problems.
1134 The perl build procedure no longer installs miniperl, nor uses
1135 the installed miniperl. It is recommended that you delete
1139 This weekend the ports tree will be updated to a new layout.
1140 It will be in an inconsistent state until noted in the UPDATING
1141 file, or with asami-san's message to the relevant mailing
1142 lists. With this new layout, you'll need to update the whole
1143 tree for anything to work.
1146 There was a change in the passwd format. Need more information.
1149 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1150 place. Please update boot loader (not the boot blocks) at the
1151 same time as your kernel.
1154 The new pmtimer device is necessary for laptops. Failure to
1155 include the device will cause suspended laptops losing time
1156 when they resume. Include
1158 in your config file and
1159 hint.pmtimer.0.at="isa"
1160 to your /boot/device.hints file.
1163 The random device has been turned into a (pseudo-)device,
1164 rather than an option. The supplied kernel config files have
1165 been updated. You will need to do something similar in your
1166 own kernel config file.
1171 If you prefer to load the loadable module, you need to do
1175 The random device module has been renamed from randomdev.ko to
1176 random.ko. You will need to edit your /boot/loader.conf to
1177 reflect this if you load this module at boot time.
1178 The line should read:
1182 The SMPNG commit has happened. It should work, but if it
1183 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1184 to be a variety of minor issues. Please see 20000905 to make
1185 sure you don't have model loading problems which might at
1186 first blush appear related to SMP.
1189 nsswitch has been imported from NetBSD. Among other things,
1190 this means that /etc/host.conf is no longer used. See
1191 nsswitch.conf(5) instead. Note that at boot time rc.network
1192 will attempt to produce a new nsswitch.conf file for you if you
1193 don't have one, and you have host.conf.
1196 The ucred structure changed size. This breaks the interface
1197 that mountd uses. Trying to use an older mountd with a newer
1198 kernel guarantees a panic. This means that you need to use
1199 kernels newer than today only with matching mountd, but you
1200 needed to do that anyway with the boot loader changes.
1203 The boot loader has been updated. The new default kernel is
1204 now /boot/kernel/kernel.ko. The new default module location
1207 You *MUST* upgrade your boot loader and kernel at the same time.
1208 The easiest way to do this is to do the buildworld/buildkernel/
1209 installkernel/installworld dance.
1211 Furthermore, you are urged to delete your old /modules directory
1212 before booting the new kernel, since kldload will find stale
1213 modules in that directory instead of finding them in the correct
1214 path, /boot/kernel. The most common complaint that this cures
1215 is that the linux module crashes your machine after the update.
1217 if [ ! -d /boot/kernel.old ]; then
1218 mv /modules.old /boot/kernel.old
1219 chflags noschg /kernel.old
1220 mv /kernel.old /boot/kernel.old/kernel.ko
1221 chflags schg /boot/kernel.old/kernel.ko
1225 A new issue with the sendmail upgrade has come to light.
1226 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1227 incorrectly install the default aliases in /etc/mail rather than
1228 move the old one from /etc. So you'll need to manually move the
1229 file, create a symbolic link, remove the old /etc/aliases.db and
1230 run newaliases. For safety sake, you should stop sendmail
1231 while doing this and run the upgrade when locally sourced email
1232 is not likely to be generated.
1235 /boot/device.hints is now required for installkernel to
1236 succeed. You should copy GENERIC.hints for your architecture
1237 into /boot/device.hints. If and only if you compile hints
1238 into your kernel, then this file may be empty. Please note,
1239 if you have an empty or missing /boot/device.hints file and
1240 you neglected to compile hints into your kernel, no boot
1241 messages will appear after the boot loader tries to start the
1245 If you do NOT have ``options RANDOMDEV'' in your kernel and
1246 you DO want the random device then add randomdev_load="YES" to
1250 suidperl is now always built and installed on the system, but
1251 with permissions of 511. If you have applications that use
1252 this program, you are now required to add ENABLE_SUIDPERL=true
1253 to /etc/make.conf. If you forget to do this,
1254 chmod 4511 /usr/bin/suidperl
1255 will fix this until the next build.
1258 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1259 visible changes that may immediately affect your configuration
1261 - New default file locations from src/contrib/sendmail/cf/README
1262 - newaliases limited to root and trusted users
1263 - MSA port (587) turned on by default
1264 - New queue file naming system so can't go from 8.11 -> 8.9
1265 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1266 - FEATURE(`nullclient') is more full featured
1267 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1268 - mail.local FreeBSD-only -b option changed to -B

1273 specifically define BUILD_SUIDPERL to "true" for it to be build.
1274 Furthermore, we recommend that you remove /usr/bin/sperl* and
1275 /usr/bin/suidperl files from your system unless you have a
1276 specific use for it.
1279 Networking defaults have been tightened. Anybody upgrading
1280 /etc/defaults/rc.conf needs to add the following lines to
1281 /etc/rc.conf if they want to have the same setup
1282 afterwards (unless the variables already are set, of course):
1283 # Enable network daemons for user convenience.
1285 portmap_enable="YES"
1286 sendmail_enable="YES"
1289 If you have null_load="YES" in your /boot/loader.conf, you
1290 will need to change that to nullfs_load="YES".
1293 The "installkernel" target has changed slightly. Now even if
1294 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1295 it will install the MYKERNEL file (built with the buildkernel
1296 target) as /kernel rather than /MYKERNEL. Those who have
1297 updated their /boot/loader.conf files to point to /MYKERNEL
1298 should remove that entry or perform manual rename of /kernel
1302 If you use CVSUP or CTM to get CVS trees, AND you used to get
1303 the old crypto files from internat.freebsd.org AND you check
1304 out files from the CVS tree with the cvs command, please read
1305 http://people.freebsd.org/~imp/internat.txt
1306 for details on potential problems that you might have and how
1309 If you are merely a mirror, or don't answer yes to each of the
1310 clauses above, you needn't worry.
1313 /etc/security has been updated to print the inode number of
1314 setuid programs that have changed. You will see a large spike
1315 in the number of changed programs the first time when you run
1316 mergemaster to get a new /etc/security.
1319 /dev/random now has good entropy collection (from the keyboard
1320 and sysmouse drivers). Please ensure that either `options
1321 RANDOMDEV' is present in your kernel config file or that
1322 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1323 not have the /dev/random driver, OpenSSL (and consequently
1324 lots of crypto tools (like SSH)) will fail with strange
1325 errors. (see below, 20000624).
1327 FreeBSD-current is safe again to run Crypto.
1330 phk made the malloc default options AJ. This may slow things
1331 down and uncover other latent bugs in the code. If you need to
1332 run at full speed, you can disable this by doing the following:
1333 ln -s aj /etc/malloc.conf
1336 libftpio's version was accidentally bumped a few days ago. This
1337 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1338 before doing your next buildworld/installworld pair. It certainly
1339 won't hurt to remove it before the update procedure. It will
1340 break fetch until a new one is built, but ftp can be used in the
1344 The crypto packages have changed for the cvsup. This has been done
1345 in a backward compatible way, but the old packages will go away at
1346 some point in the future. Look at /usr/share/examples/cvsup for
1350 With the new sys/modules/sound/drivers/*, you will need to
1351 set SYSDIR until you do an installworld after July 7th.
1354 rc.shutdown and rc will now call the rc.d scripts with start
1355 or stop. This may cause some harmless warnings from older
1356 rc.d scripts that haven't been updated.
1359 The libfetch based version of fetch has gone into the tree.
1360 Minor problems may result on some of the less popular sites,
1361 which should be reported to des@freebsd.org.
1364 From approximately this date forward, one must have the crypto
1365 system installed in order to build the system and kernel.
1366 While not technically strictly true, one should treat it as
1367 required and grab the crypto bits. If you are grabbing CVS
1368 trees, src-all and cvs-crypto should be treated as if they
1369 were required. You should check with the latest collections
1370 to make sure that these haven't changed.
1373 Mark Murray just committed the first parts of a cleanup of
1374 /dev/zero, et al. This is also cleaning up /dev/random.
1375 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1376 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1377 until Mark can merge in the fixes to this work in progress.
1378 openssh and openssl should not be used to generate keys from this
1379 date to the completion of the work.
1381 If you must operate at this reduced level of security, add '
1382 options RANDOMDEV' to your kernel or modload the randomdev
1383 module. You may also need to copy a new MAKEDEV to /dev and
1384 recreate the random and urandom devices.
1387 The license on the softupdates is now a standard 2 clause
1388 BSD license. You may need to remove your symbolic links
1389 that used to be required when updating.
1392 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1393 the config file update procedure.
1394 http://people.freebsd.org/~imp/config-upd.html
1395 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1396 isn't buildable. However, you can generate a LINT file:
1397 cd /sys/<ARCH>/conf && make LINT
1400 Binutils 2.10 have hit the tree, or will shortly. As soon
1401 as they do, the problem noted in 20000522 will be resolved and
1402 that workaround will no longer be required.
1405 phk removed the compatibility creation of wd devices in the
1406 ad driver. If you haven't done so already, you must update
1407 your fstab, etc to use the ad devices instead of the wd
1410 In addition, you'll need to update your boot blocks to a
1411 more modern version, if you haven't already done so. Modern
1412 here means 4.0 release or newer (although older releases
1416 Peter took an axe to config(8). Be sure that you read his mail
1417 on the topic before even thinking about updating. You will
1418 need to create a /boot/device.hints or add a hints directive
1419 to your config file to compile them in statically. The format
1420 of the config file has changed as well. Please see GENERIC or
1421 NEWCARD for examples of the new format.
1423 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1424 says that it has been fixed, assume that must use the hints mechanism
1425 in the loader if you need to use a machine with very old ISA cards
1429 A new set of binutils went into the tree today. Anybody
1430 building a kernel after this point is advised that they need
1431 to rebuild their binutils (or better yet do a
1432 buildworld/installworld) before building a new kernel.
1434 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1435 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1436 is recommended that you don't set this option until the problem
1440 The ethernet drivers were all updated to clean up the BPF handling.
1443 The problems with boot blocks on the alphas have been corrected.
1444 This will require some care in updating alphas. A new libstand
1445 is requires for the boot blocks to build properly.
1448 Recompile all kld modules. Proper version dependency info
1452 Modules have been disconnected from the buildworld tree and
1453 connected to the kernel building instead.
1456 You may need to build gperf
1457 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1458 when upgrading from 4.0 -> current. The build system now uses
1459 an option only in -current.
1462 The method that we brand ELF binaries has changed to be more
1463 acceptable to the binutils maintainers. You will need to
1464 rebrand your ELF binaries that aren't native. One problem
1465 binary is the Linux ldconfig. After your make world, but
1466 before you reboot, you'll need to issue:
1467 brandelf -t Linux /compat/linux/sbin/ldconfig
1468 if you have Linux compatibility enabled on your machine.
1471 If you have really bad/marginal IDE drives, you may find they
1472 don't work well. Use pio mode instead. The easiest way to
1473 cope if you have a problem combination is to add:
1474 /sbin/sysctl hw.ata.ata_dma=0
1475 to the start of /etc/rc.conf.
1478 The ISA and PCI compatibility shims have been connected to the
1479 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1480 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1481 include the appropriate option in your kernel config. Drivers
1482 using the shims should be updated or they won't ship with
1483 5.0-RELEASE, targeted for 2001.
1486 We've entered the traditional post release dumping party.
1487 Large kernel changes are being committed and are in the
1488 works. It is important to keep the systems' klds and kernel
1489 in sync as kernel interfaces and structures are changing.
1490 Before reporting kernel panics, make sure that all modules
1491 that you are loading are up to date.
1494 If you are upgrading from an older version of FreeBSD, you
1495 need to update your boot blocks as well. 'disklabel -B ad0'
1496 will do the trick. This isn't critical until you remove your
1497 wd device entries in /dev, at which point your system will not
1501 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1502 to upgrade to 4.0 from 3.x.
1508 Avoid using make -j when upgrading. From time to time in the
1509 past there have been problems using -j with buildworld and/or
1510 installworld. This is especially true when upgrading between
1511 "distant" versions (eg one that cross a major release boundary
1512 or several minor releases, or when several months have passed
1513 on the -current branch).
1515 Sometimes, obscure build problems are the result of environment
1516 poisoning. This can happen because the make utility reads its
1517 environment when searching for values for global variables.
1518 To run your build attempts in an "environmental clean room",
1519 prefix all make commands with 'env -i '. See the env(1) manual
1520 page for more details.
1524 If you are updating from a prior version of FreeBSD (even one just
1525 a few days old), you should follow this procedure. With a
1526 /usr/obj tree with a fresh buildworld,
1527 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1528 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1530 To just build a kernel when you know that it won't mess you up
1531 --------------------------------------------------------------
1532 This assumes you are already running a 5.X system. Replace
1533 ${arch} with the architecture of your machine (e.g. "i386",
1534 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1536 cd src/sys/${arch}/conf
1537 config KERNEL_NAME_HERE
1538 cd ../compile/KERNEL_NAME_HERE
1543 If this fails, go to the "To build a kernel" section.
1545 To rebuild everything and install it on the current system.
1546 -----------------------------------------------------------
1547 # Note: sometimes if you are running current you gotta do more than
1548 # is listed here if you are upgrading from a really old current.
1550 <make sure you have good level 0 dumps>
1551 <maybe fix /etc/fstab> [7]

1554 make installkernel KERNCONF=YOUR_KERNEL_HERE
1556 <reboot in single user> [3]
1557 /etc/rc.d/preseedrandom [10]
1564 To cross-install current onto a separate partition
1565 --------------------------------------------------
1566 # In this approach we use a separate partition to hold
1567 # current's root, 'usr', and 'var' directories. A partition
1568 # holding "/", "/usr" and "/var" should be about 2GB in
1571 <make sure you have good level 0 dumps>

1575 <mount current's root partition on directory ${CURRENT_ROOT}>
1576 make installworld DESTDIR=${CURRENT_ROOT}
1577 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1578 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \
1579 ${CURRENT_ROOT}/boot/device.hints # as needed
1580 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1581 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1582 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
1583 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1584 <reboot into current>
1585 <do a "native" rebuild/install as described in the previous section>
1586 <maybe install compatibility libraries from /usr/src/lib/compat>
1590 To upgrade in-place from 4.x-stable to current
1591 ----------------------------------------------
1592 # 5.x uses more space than 4.x. Also, the location of kernel
1593 # modules has changed. If you are installing 5.0 onto a 4.x
1594 # system, you'll need about 30MB of free disk space on your /
1595 # partition. If you have less than this, you may encounter difficult
1596 # to back out of problems with this procedure. If /tmp is on
1597 # the / partition, you may want to completely remove all its content
1598 # before upgrading, as this can be a common source of shortage of
1601 <make sure you have good level 0 dumps>
1602 <maybe fix /etc/fstab> [7]
1604 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
1605 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
1606 make installkernel KERNCONF=YOUR_KERNEL_HERE
1607 cd sys/boot ; make STRIP="" install [6]
1609 <reboot in single user> [3]
1610 /usr/src/etc/rc.d/preseedrandom [10]
1612 rm -rf /usr/include/g++
1617 Make sure that you've read the UPDATING file to understand the
1618 tweaks to various things you need. At this point in the life
1619 cycle of current, things change often and you are on your own
1620 to cope. The defaults can also change, so please read ALL of
1621 the UPDATING entries.
1623 Also, if you are tracking -current, you must be subscribed to
1624 freebsd-current@freebsd.org. Make sure that before you update
1625 your sources that you have read and understood all the recent
1626 messages there. If in doubt, please track -stable which has
1627 much fewer pitfalls.
1629 [1] If you have third party modules, such as vmware, you
1630 should disable them at this point so they don't crash your
1633 [2] If you have legacy ISA devices, you may need to create
1634 your own device.hints to reflect your unique hardware
1637 [3] From the bootblocks, boot -s, and then do
1642 adjkerntz -i # if CMOS is wall time
1643 Also, when doing a major release upgrade, it is required that
1644 you boot into single user mode to do the installworld.
1645 For the 4.x -> 5.0 upgrade, you will also see many messages about
1646 needing to recompile your userland. These are harmless and can
1647 be ignored while you proceed to the next step.
1649 [4] Note: This step is non-optional. Failure to do this step
1650 can result in a significant reduction in the functionality of the
1651 system. Attempting to do it by hand is not recommended and those
1652 that pursue this avenue should read this file carefully, as well
1653 as the archives of freebsd-current and freebsd-hackers mailing lists
1654 for potential gotchas.
1656 [5] Usually this step is a noop. However, from time to time
1657 you may need to do this if you get unknown user in the following
1658 step. It never hurts to do it all the time. You may need to
1659 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1660 install) after the buildworld before this step if you last updated
1661 from current before 20020224 or from -stable before 20020408.
1663 [6] 4.x boot loader can be used to boot a 5.x system, however
1664 it is difficult to do that at best. If you wish to try, then
1665 you should interrupt the boot and at the ok prompt type:
1667 ok boot /boot/kernel/kernel
1668 If this fails to work, you must install a new boot loader as
1671 [7] Before you upgrade, please make sure that you are not using
1672 compatibility slices. These are device names of the form, on i386
1673 and other architectures that use MBR slicing, /dev/ad0a without the
1674 actual slice name. Chances are excellent that these will break.
1675 You generally must update these entries to use the post FreeBSD
1676 2.x form of /dev/ad0s1a.
1678 [8] In order to have a kernel that can run the 4.x binaries
1679 needed to do an installworld, you must include the COMPAT_FREEBSD4
1680 option in your kernel. Failure to do so may leave you with a system
1681 that is hard to boot to recover.
1683 [9] When checking out sources, you must include the -P flag to have
1684 cvs prune empty directories. Also, if CPUTYPE is defined in your
1685 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1686 operator, so that buildworld can override the CPUTYPE if it needs to.
1687 In case you would like to avoid installing new packages of everything,
1688 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1689 compatibility libraries are build which should allow you to continue
1690 using your existing software for a while.
1692 [10] In order to create temporary files, /dev/random must be
1693 initialized by feeding data into it. /etc/rc.d/preseedrandom
1697 This file contains a list, in reverse chronological order, of major
1698 breakages in tracking -current. Not all things will be listed here,
1699 and it only starts on March 15, 2000. Updating files can found in
1700 previous releases if your system is older than this.
