13 NOTE TO PEOPLE WHO THINK THAT FreeBSD 6.x IS SLOW:
14 FreeBSD 6.x has many debugging features turned on, in
15 both the kernel and userland. These features attempt to detect
16 incorrect use of system primitives, and encourage loud failure
17 through extra sanity checking and fail stop semantics. They
18 also substantially impact system performance. If you want to
19 do performance measurement, benchmarking, and optimization,
20 you'll want to turn them off. This includes various WITNESS-
21 related kernel options, INVARIANTS, malloc debugging flags
22 in userland, and various verbose features in the kernel. Many
23 developers choose to disable these features on build machines
24 to maximize performance.
27 Netgraph changed its message format slightly to align the data
28 portion well on 64 bit machines.
29 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
30 pppoed, bluetooth, ATM) should be recompiled when a new kernel
34 IPFW has been converted to use PFIL_HOOKS. This change is
35 transparent to userland and preserves the ipfw ABI. The ipfw
36 core packet inspection and filtering functions have not been
37 changed, only how ipfw is invoked is different. Note that
38 "option PFIL_HOOKS" is required to use IPFIREWALL compiled
39 into the kernel or as KLD.
42 The RANDOM_IP_ID option has been replaced by the sysctl
43 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
44 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
47 The size of 'struct ifnet' has changed due to the addition of the
48 if_carp placeholder. All kernel modules implementing network
49 interfaces must be recompiled as a result.
52 Module loading has been fixed. Some older installations will
53 drop proper module_path initialization and modules will fail to
54 load properly. If you have a line in /boot/loader.rc that says:
55 "initialize drop", do (i386 only):
56 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
57 chown root:wheel /boot/loader.rc
58 chmod 444 /boot/loader.rc
61 making /dev/(null|zero) into a module proved to be too unpopular,
62 so this bit has been revoked from the previous (20040801) entry.
65 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
66 so you may wish to add them to your kernel config file. See
70 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
71 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
72 has broken C++ ABI compatibility with previous releases yet again
73 and users will have to rebuild all their C++ programs with the new
74 compiler. If you are getting run-time error such as
75 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE"
76 This entry does apply to you.
78 A new unit-at-a-time optimization mode, which is default in this
79 compiler release, is more aggressive in removing unused static
80 symbols. This is the likely cause of 'make buildworld' breakages
81 with non-default CFLAGS where optimization level is set to -O2 or higher.
83 With the upgrade of the system compiler, the kernel has been upgraded
84 to match the new system compiler. This makes it impossible to build
85 a new kernel with the old compiler. Upgrade your system via
86 make buildworld and make kernel (see below) to fix this problem.
89 The size of 'struct ifnet' has changed due to the addition of
90 the IFF_NEEDSGIANT flag (and what it implies). All kernel
91 modules implementing network interfaces must be recompiled as
95 The sound device drivers are renamed. `sound' is always required,
96 while `snd_*' should be configured accordingly to your hardware.
97 Refer to NOTES for the detail of the drivers.
100 __FreeBSD_version bumped to 502122.
103 The console initialization on Alpha has been reworked and is now
104 identical to other platforms. This means that the hardcoding of
105 the serial console and the debug port has been removed. As such,
106 hints are now required for the sio(4) driver to become a console
107 or debug port. The NO_SIO option has been decommissioned because
111 A revamp of the debugging code in the kernel with some visible
112 changes beyond just the debugging experience:
113 o The DDB option is now specific to the DDB debugger backend
114 and should not be used any more for conditional compilation
115 of debugging code for when debugging is enabled. Use the KDB
117 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
118 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
119 respectively. This is in line with the first bullet.
120 o The remote GDB support has been untangled from DDB and needs
121 to be enabled separately now. Use the GDB option for this.
122 o The GDB_REMOTE_CHAT option has been removed. Support for this
123 homegrown feature is discontinued. The GDB remote protocol
124 supports console output and it makes sense to use that.
125 o The DDB_NOKLDSYM option has been removed. The DDB debugger
126 now supports both direct symbol table lookups as well as KLD
127 symbol lookups through the linker.
130 Bluetooth code has been marked as non-i386 specific.
131 __FreeBSD_version has been bumped to 502121 to mark this change.
134 The native preemption has been added to the kernel scheduler.
135 There is some report that the ULE scheduler was broken in some
136 machines and we encourage users using the ULE scheduler either
137 stick with a known good kernel, or temporarily switch to the 4BSD
138 scheduler as a workaround.
141 The netgraph ABI version number has been incremented to indicate
142 an incompatible change in the ABI. Old netgraph nodes will refuse
143 to attach until recompiled. Netgraph now uses mbuf tags to move
144 metadata and this commit removes its home-grown metadata facility.
145 Nodes should just recompile, unless they use metadata, in which
146 case the changes are simple; the file ng_ksocket.c serves as an
147 example of such changes.
149 This also broke i4b, although the compile problem has been papered
153 ACPI has been updated to disable known-bad BIOS revisions. A message
154 will be printed on the console indicating that ACPI has been disabled
155 automatically and that the user should use a newer BIOS, if possible.
156 If you think ACPI does work on your system and want to override
157 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
161 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
162 separated now. It uses the newly created "_pflogd" user/group
163 combination. If you plan to use pflogd(8) make sure to run
164 mergemaster -p or install the "_pflogd" user and group manually.
167 Network interface cloning has been overhauled. This change will
168 require a recompile of modules using cloning and modification of
169 external ones to the new API. __FreeBSD_version has been bumped
170 to 502119 to mark this change. Additionally, users creating
171 stf(4) interfaces via "ifconfig stf" will need to update their
172 scripts as this will create an interface named "stf" instead of
173 "stf0" and ifconfig will not print "stf0" to stdout.
176 On 20040524, the /etc/rc.d/nsswitch script was modified to
177 automatically create /etc/nsswitch.conf on startup if it did
178 not already exist. Unfortunately, an error in the man page
179 was carried over to the script, resulting in incorrect
180 nsswitch settings. The simplest remedy is to remove both
181 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
182 during the next reboot.
185 The return value of sema_timedwait(9) has been changed to
186 make it consistent with cv_timedwait(9). Be sure to recompile
187 the ips module and any third-party modules which call
191 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
192 Make sure to recompile modules and any userland that makes use of
193 sizeof(struct ifnet). In order to get the altq headers in place
194 please recompile and reinstall world.
197 Splitting kern_thread.c into 2 files (adding kern_kse.c)
198 requires that you re-run config after updating your tree.
201 The MIDI drivers have been removed. Until the new module-friendly
202 ones are merged, remove or comment out midi and seq from your
203 kernel configuration.
206 Due to a new option in ipfw (versrcreach) the ipfw(8) command
207 needs to be recompiled. Normal accept/reject rules without
208 options are not affected but those with options may break until
209 ipfw(8) is recompiled.
212 Due to changes in the callout ABI, kernels compiled after this
213 date may be incompatible with kernel modules compiled prior to
217 The PCI bus power state stuff has been turned on. If this causes
218 problems for your system, please disable it using the tunable
219 hw.pci.do_powerstate=0.
222 The bulk of the pci problems have been fixed, although the floppy
223 drive is still broken.
226 A substantial update to the pci bus resource and power management
227 have been committed. Expect a bumpy ride for a few days until
228 the unanticipated problems have been resolved.
231 Due to changes in the the Yarrow initialization process,
232 /dev/random needs to be fed before operations requiring
233 temp files can succeed in single user mode. This includes
234 running "make installworld". /dev/random may be fed by running
235 "/etc/rc.d/initrandom start" or with 20040415 source by running
236 "/etc/rc.d/preseedrandom".
239 The debug.mpsafenet tunable controls whether the kernel Giant
240 lock is held across the lower levels of the network stack, and
241 by default is turned off. In the few days following 20040322,
242 the behavior of debug.mpsafenet will change such that this
243 tunable controls Giant over all levels of the network stack.
244 If you are currently setting debug.mpsafenet to 1, you should
245 set it back to 0 (the default) again during the change-over.
246 An additional note will be added to UPDATING when sufficient
247 locking is merged to permit this to take place.
250 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
251 64-bits. This is a very major incompatible change, so people
252 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
253 detailed instructions on how to make this upgrade. People
254 upgrading FreeBSD on other platforms can ignore this event.
257 The packet filter (pf) is now installed with the base system. Make
258 sure to run mergemaster -p before installworld to create required
259 user account ("proxy"). If you do not want to build pf with your
260 system you can use the NO_PF knob in make.conf.
261 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
262 pf system consists of the following three devices:
264 device pflog # optional
265 device pfsync # optional
268 If you are having trouble with the libc_r -> libpthread transition
269 (see the 20040130 entry), place the following lines at the top of
272 libc_r.so.5 libpthread.so.1
273 libc_r.so libpthread.so
275 This will cause all programs and libraries linked against libc_r
276 to use libpthread instead.
279 Some sshd configuration defaults have changed: protocol version 1
280 is no longer enabled by default, and password authentication is
281 disabled by default if PAM is enabled (which it is by default).
282 OpenSSH clients should not be affected by this; other clients may
283 have to be reconfigured, upgraded or replaced.
286 The ABIs defined in <resolv.h> and <netdb.h> have been updated
287 to support improved reentrancy. Multi-threaded programs that
288 reference the "_res" or "h_errno" symbols may experience some
289 problems if they are not recompiled. Single-threaded programs
290 should remain unaffected.
293 routed has been updated in the base system from the vendor
294 sources, routed v2.27, from rhyolite.com. This change means that
295 for users who use RIP's MD5 authentication feature, FreeBSD
296 -CURRENT's routed is now incompatible with previous versions
297 of FreeBSD; however it is now compatible with implementations
298 from Sun, Cisco and other vendors.
301 The tcpcb structure has changed and makes a recompile of libkvm
302 and related userland network utilities necessary.
305 The cdevsw structure has changed in two externally visible ways.
306 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
307 Second, the d_version field must be filled in with D_VERSION.
308 Drivers outside the tree will need to be updated.
311 The /etc/rc.d/ttys script has been removed. It is no longer
312 necessary since devfs has been mandatory for some time.
315 libkse has been renamed back to libpthread and is now the
316 default threads library. The gcc -pthread option has also
317 been changed to link to libpthread instead of libc_r. For
318 alpha and sparc64 machines, libkse is not renamed and links
319 are installed so that libpthread points to libc_r. Until
320 the ports system is updated to handle this change, it is
321 recommended that folks install an /etc/libmap.conf(5) that
322 maps libc_r to libpthread. If you have any binaries or
323 libraries linked to libkse, then it is also recommended
324 that you map libkse to libpthread. Anyone that is using
325 nvidia supplied drivers and libraries should use a libmap.conf
326 that maps libpthread to libc_r since their drivers/libraries
327 do not work with libpthread.
330 ULE has entered into its probationary period as the default scheduler
331 in GENERIC. For the average user, interactivity is reported to be
332 better in many cases. On SMP machines ULE will be able to make more
333 efficient use of the available parallel resources. If you are not
334 running it now, please switch over, replacing the kernel option
335 SCHED_4BSD with SCHED_ULE.
338 Move LongRun support out of identcpu.c, where it hardly
339 belongs, into its own file and make it opt-in, not mandatory,
340 depending on CPU_ENABLE_LONGRUN config(8) option.
343 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
344 if the login process is unable to successfully set the
345 process credentials to include all groups defined for the
346 user. The current kernel limit is 16 groups; administrators
347 may wish to check that users do not have over 16 groups
348 defined, or they will be unable to log in.
351 The ACPI module has been reactivated. It is no longer required
352 to compile ACPI support into kernels statically.
355 The statfs structure has been updated with 64-bit fields to
356 allow accurate reporting of multi-terabyte filesystem
357 sizes. You should build world, then build and boot the new kernel
358 BEFORE doing a `installworld' as the new kernel will know about
359 binaries using the old statfs structure, but an old kernel will
360 not know about the new system calls that support the new statfs
362 Note that the backwards compatibility is only present when the
363 kernel is configured with the COMPAT_FREEBSD4 option. Since
364 even /bin/sh will not run with a new kernel without said option
365 you're pretty much dead in the water without it. Make sure you
366 have COMPAT_FREEBSD4!
367 Running an old kernel after a `make world' will cause programs
368 such as `df' that do a statfs system call to fail with a bad
369 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
370 that cfsd (ports/security/cfs) needs to be recompiled after
371 these changes are installed.
373 ****************************DANGER*******************************
375 DO NOT make installworld after the buildworld w/o building and
376 installing a new kernel FIRST. You will be unable to build a
377 new kernel otherwise on a system with new binaries and an old
381 Some netgraph string length constants have been changed. This
382 change requires the netgraph kernel modules and all netgraph
383 userland components to be in sync. Especially users who require
384 netgraph to boot need to make sure to have world and kernel in
385 sync before rebooting.
388 Hyperthreading logical CPU's are no longer probed by default
389 when using the MP Table. If ACPI is being used, then logical
390 CPUs will be probed if hyperthreading is enabled in the BIOS.
391 If ACPI is not being used and hyperthreading is enabled in the
392 BIOS, logical CPUs can be enabled by building a custom kernel
393 with the option MPTABLE_FORCE_HTT enabled.
396 The i386 APIC_IO kernel option has been replaced by
397 'device apic'. The ACPI module has also been temporarily
398 disabled, so ACPI must be statically compiled into your
399 kernel using 'device acpi' if you wish to use the ACPI driver.
402 The API and ABI of struct ifnet have been changed by removing
403 the if_name and if_unit members and replacing them with
404 if_xname, if_dname, and if_dunit. All network drivers and most
405 userland programs which include net/if_var.h must be updated
406 and recompiled. __FreeBSD_version has been bumped to 501113 to
410 Changes to the cdevsw default functions have been made to remove
411 the need to specify nullopen() and nullclose() explicitly.
412 __FreeBSD_version bumped to 501110.
415 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
416 mount_cd9660(8) need to be in sync with kernel.
419 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
420 also be explicitly configured. Previously this dependency was
421 magically handled through some cruft in net/pfil.h; but that has
422 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
423 will fail with obtuse errors in ip_fil.c.
426 Fix a bug in arplookup(), whereby a hostile party on a locally
427 attached network could exhaust kernel memory, and cause a system
428 panic, by sending a flood of spoofed ARP requests. See
429 FreeBSD-SA-03:14.arp.
432 A change to /etc/defaults/rc.conf now causes inetd to be started
433 with `-C 60' if it is not overridden in /etc/rc.conf. This
434 causes inetd to stop accepting connections from an IP address
435 that exceeds the rate of 60 connections per minute.
438 The following rc.d scripts have been removed and should be
439 deleted from your installation: atm2.sh atm3.sh devdb
440 localdaemons network1 network2 network3. Depending on when
441 you last updated world and used mergemaster(8) you may or
442 may not have problems during the rc boot sequence. The simplest
443 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
444 The atm2.sh atm3.sh and devdb scripts were removed some time
445 ago, so depending on when you installed -CURRENT these scripts
446 may or may not exist on your system.
449 ATAng has been committed. You need to build world as sys/ata.h
450 has changed, and userland atacontrol depends on it.
451 If you use ATA SW raids you need "device ataraid" in your
452 kernel config file, as it is no longer pulled in automatically.
455 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
456 Among other things, this changes the device enumeration to be
457 closer to Solaris. Be aware that, this can even cause the machine
458 to not boot without manual intervention before the fstab is adjusted.
461 All current USB and Firewire quirks in da(4) have been deprecated
462 and will be removed for 5.2. If this causes failure for your
463 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
464 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
465 so the quirk can be re-enabled.
468 Problems with entry 20030714 have been corrected and no known issues
469 with /rescue and -j exist for host systems after this point in time.
472 FPU-less support has been removed from FreeBSD. Chances are you won't
473 notice. 386+387 support should still work after this change, but
474 it is now a minimum requirement for the i386 port that you have real
478 Some people are having problems with changes related to /rescue.
479 If you are building -j N, you will need to define NO_RESCUE. Others
480 will need to define it if /rescue has issues with their environment.
481 People should report those issues to current@.
484 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
485 across this point. Further, it might be a good idea to remove
489 Remove deprecated locale names and transition period code
490 for them, finishing switching to the new scheme. Check your
491 LANG environment variable.
494 CCD has been changed to be a fully GEOMified class. Kernel
495 and ccdconfig(8) needs to be in sync, this is particularly
496 important to remember beforehand if your source tree is on
497 a ccd device. Consider making a copy of the old ccdconfig
498 into /boot/kernel.good or wherever you keep your backup
502 There was a small window in which sed(1) was broken. If you
503 happen to have sed(1) installed during that window, which is
504 evidenced by an inability to build world with the failure
505 given below, you need to manually build and install sed(1)
506 (and only sed(1)) before doing anything else. This is a one-
507 time snafu. Typical failure mode:
509 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
510 targmatch.h:7:1: null character(s) ignored
511 targmatch.h:12:1: null character(s) ignored
512 targmatch.h:16:1: null character(s) ignored
515 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
516 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
517 usr.bin/sed/process.c).
520 Kerberos 5 (Heimdal) is now built by default. Setting
521 MAKE_KERBEROS5 no longer has any effect. If you do NOT
522 want the "base" Kerberos 5, you need to set NO_KERBEROS.
525 groff has been updated. If you try to do a buildworld and
526 get an infinite loop in troff, update to May 4th or newer. If you
527 have a newer kernel than userland, you may need to set the OSRELDATE
528 to 500110 in your environment before starting a buildworld.
531 The old rc system has been removed. Please report any problems
532 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
533 Your personal versions of these files will not be removed, so you can
534 continue to use them. However, you should take great care when updating,
535 especially when using mergemaster, since the compatibility code that
536 utilizes these old scripts has also been removed.
539 A bug has been fixed in /dev/devctl which would cause devd
540 to hang on boot, were it not for a workaround in devd. The
541 work around in devd will be removed around 20030507. You
542 have until then to upgrade your kernel before updating
543 userland. In general, you should have a userland and
544 kernel that's in sync with each other. However, given the
545 effects of this bug (hang on boot when starting devd), some
549 Alphas with libc from between 20030312 and 20030329 exhibit
550 floating point exceptions (FPEs), most notably in awk(1)
551 while upgrading the system through a buildworld.
553 So, to successfully upgrade your Alpha, you must either
554 downgrade your libc.so to a pre-20030312 version, or update
555 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
556 to CFLAGS, then forcibly rebuild and install libc:
558 cd /usr/src/lib/libc && \
559 make cleandir && make obj && \
560 make -DNOMAN -DNOPROFILE all && \
561 make -DNOMAN -DNOPROFILE install
564 sendmail 8.12.7 has been imported. It has one important
565 change for IPv6 users. The default submit.mc now uses
566 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
567 used to connect to the MTA. Users on IPv6-only machines
568 will need to edit /etc/mail/submit.mc appropriately.
571 NODEVFS option has been removed and DEVFS thereby made standard.
572 This makes all references to MAKEDEV obsolete, and they should
573 be removed when convenient.
576 The name of the device for the ofw console has changed, sparc64 users
577 must run mergemaster to update their installed /etc/ttys.
580 The scheduler framework has grown a second scheduler and consequently
581 you must specify one and only one scheduler in your kernel config.
582 The cvs config files have been updated to use the old scheduler
583 which may be selected via 'options SCHED_4BSD'. If you would like
584 to try the new, much more experimental, scheduler please try
585 'options SCHED_ULE' and contribute to the arch@ discussion.
588 A new version of the wi driver has been imported into the tree.
589 One now must have device wlan in the config file for it to operate
592 In addition, there have been some changes to how wi devices are
593 configured for point to point links to bring it more in line
594 with the former way of doing things, as well as compatibility
598 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
599 used an incompatible form of ABI for returning structures and unions
600 which FreeBSD's GCC maintainers were not aware of relative to previous
601 versions of FreeBSD. We have gone back to the ABI for now, and any
602 code compiled which is required to interoperate with other code (not
603 built at the same time) returning structs or unions should be
607 A name change in /etc/netconfig has been reverted to stay
608 compatible with suns TIRPC and also with NetBSD. You need
609 to run mergemaster after make world. A new libc does still work
610 with an outdated /etc/netconfig for some time, but you'll get
611 a warning. This warning will be removed in 20030301.
614 The recent binutils upgrade marks a kernel flag day on
615 sparc64: modules built with the old binutils will not work
616 with new kernels and vice versa. Mismatches will result in
617 panics. Make sure your kernel and modules are in sync.
620 The value of IPPROTO_DIVERT has changed. Make sure to keep
621 your kernel, netstat, natd and any third-party DIVERT
625 Old, compatibility slices have been removed in GEOM kernels.
626 This means that you will have to update your /etc/fstab to
627 not use disk devices of the form /dev/ad0a. Instead, you
628 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
629 partition really is on. The old device names have gone
630 away, so if you use them anywhere else, you must also adjust
631 those uses. (This doesn't affect the disks formatted in
632 the ``dangerously-dedicated'' mode.)
635 Alphas with kernels from between 20020830 and 20021023 and/or
636 rtld (ld-elf.so.1) older than 20021023 may experience problems
637 with groff while doing a buildworld (kernel: "out of memory",
638 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
639 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
641 So, to successfully upgrade your Alpha, you must either
642 upgrade your kernel and rtld first (which might be a bit
643 tricky), or avoid running the bootstrapped groff during the
644 "transitional" buildworld. To avoid running groff during the
645 transitional upgrade run make buildworld with -DNOMAN,
646 -DNO_SHAREDOCS, and -DNO_LPR.
649 gcc has been upgraded to 3.2. It is not all binary compatible
650 with earlier versions of gcc for c++ programs. All c++
651 programs and libraries need to be recompiled.
653 Also, if you encounter g++ issues, rm /usr/include/g++/* before
654 doing an installworld to make sure that stale files are removed.
657 Our /etc/termcap now has all the entries from the XFree86 xterm
658 almost unchanged. This means xterm now supports color by default.
659 If you used TERM=xterm-color in the past you now should use
660 TERM=xterm. (xterm-color will lead to benign warnings).
663 A "bug" in gcc(1) that was hiding warning in system headers was
664 fixed. It's probably time to add -DNO_WERROR to your make line
668 COPY is being deprecated. The 20010530 change was reverted, as
669 it causes far more pain than was expected, and to always compare
670 before installing, please use INSTALL="install -C" again. The
671 -C option is now silently ignored when used with the -d option.
674 Problems with libc_r clients like KDE and GNOME have been resolved.
675 There are still some minor problems with some signals but the
676 system is stable enough for general use again. SMP is less so than UP
677 but each can successfully complete multiple buildworlds.
678 Libkvm needs to be recompiled due to KSE.
681 Now would be a bad time to upgrade. Something in or near the
682 KSE commit totally broke programs using libc_r like KDE and
686 The k5su utility installed as part of Kerberos 5 is no longer
687 installed with the set-user-ID bit set by default. Add
688 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
689 with the set-user-ID bit set.
692 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
693 Unfortunately our native GDB (at version 4.18) does not understand
694 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
695 generated debugging information for our native GDB.
698 Due to the way CVS works, it may not properly update src/contrib/gcc
699 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
700 and then do a cvs update.
703 When exec'ing set[ug]id executables, the kernel now ensures that the
704 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
707 New sendmail startup scripts have been installed to make it
708 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
709 variable sendmail_enable to "NO" no longer prevents any sendmail
710 daemons from starting. Instead, either set sendmail_enable to
711 "NONE" or change mta_start_script to a script for starting
712 an alternative MTA. Setting mta_start_script to "" will
713 also prevent any MTA from being started at boot.
716 UCONSOLE is no longer a valid kernel option.
719 FreeBSD 5.0 DP-1 was basically branched today.
722 Warnings are now errors in the kernel. Unless you are a developer,
723 you should add -DNO_WERROR to your make line.
726 sendmail 8.12.2 has been imported. The sendmail binary is no
727 longer a set-user-ID root binary and the infrastructure to support
728 command line mail submission has changed. Be sure to run
729 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
730 and /etc/mail) and read /etc/mail/README for more details.
732 Due to the import of sendmail 8.12.2, a new user and group are
733 required in order for sendmail to run as a set-group-ID
734 binary. A 'make installworld' will use the new user and group
735 to set the owner and group of /var/spool/clientmqueue and will
736 fail if the new user and group do not exist. The 'smmsp' user
737 and group must be merged from src/etc/group and
738 src/etc/master.passwd before using 'make installworld'.
739 'mergemaster -p' will do this. You may need to install
740 mergemaster before this will work if you are updating from a
741 very old version of current. The updating recipe has changed
745 The preferred configuration method for PAM is now /etc/pam.d/
746 rather than /etc/pam.conf. If you have an unmodified
747 pam.conf, just delete it after your next mergemaster run. If
748 you have local modifications, you can use
749 /usr/src/etc/pam.d/convert.pl to incorporate them into your

760 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
761 started out its life in the ISDN4BSD project as an offspring
762 from sys/net/if_spppsubr.c, which eventually got a life of its
763 own. All the accumulated features and bug fixes of the i4b
764 version have now been merged back into the base system's
765 version now. The only user-visible change resulting from this
766 is that i4b's sppp(4) interfaces are to be managed with
767 spppcontrol(8) again, since ispppcontrol(8) has been retired
768 as well. (There has never been rc file support for
769 ispppcontrol in -current, but only in -stable. That will be
770 reverted by the time the changes are MFCed.)
773 The fdc(4) driver has been updated and now automatically
774 recognizes media in `standard' formats (like 1440 KB and
775 720 KB for a 3.5" high-density drive) when accessing the
776 default device node (e. g. /dev/fd0). The old variety of
777 floppy device nodes /dev/fd*.* is no longer present by
778 default, devices can be created (in DEVFS) on demand. They
779 will need to be customized then for `odd' densities using
783 The bugs in procfs' debugging support code have been fixed,
784 and truss(1) now works again.
787 Daily security checks have been split out to use the periodic(8)
788 scripts. Some change in configuration may be necessary. Please
790 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
794 sos added VCD/SVCD support to ata driver and that needs the
795 kernel and burncd to be in sync.
798 The procfs pseudo-filesystem has now been converted to use the
799 pseudofs framework. If you have 'options PROCFS' in your
800 kernel config, you'll need to add 'options PSEUDOFS' if it's
803 This change temporarily breaks truss(1); use ktrace(1) instead
804 until the issue has been resolved.
807 A security hole in OpenSSH involving `UseLogin yes' has been
811 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
812 after this date. You need to do this only once.
815 Most of the awk issues have been resolved. Some rough
816 edges may be left, but for the most part things should be
817 back to "normal." For CURRENT's usual definition of "normal."
820 Awk has been upgraded to the one true awk from bell labs. Expect
821 choppy waves in the upgrade process.
824 The asr driver problem has been resolved.
827 Due to changes in other parts of the system, the asr driver
828 now causes the system to panic on boot. Do not use it pending
829 correction. Comment it out of any kernel config file that you
830 try to use from this date forward.
833 When crossbuilding, use TARGET=xxx where you used to use
834 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
835 unless you are changing both of them. To cross build pc98 on
836 an alpha, for example, you need to set TARGET=pc98 and
840 The kernel interface that burncd depends on has changed.
841 You must recompile both the kernel and userland applications
845 When crossbuilding, please set TARGET_ARCH rather than
846 MACHINE_ARCH to indicate the target. In the future, one will
847 set TARGET_MACHINE where you set MACHINE now. At the moment,
848 setting MACHINE alone for same MACHINE_ARCH machines works
849 (eg, you can build pc98 on an i386 machine and vice versa).
852 Some weird problems result from using ACPI on some machines.
853 To disable ACPI you can add
854 hint.acpi.0.disabled="1"
855 to /boot/loader.conf (or by putting set X=Y at the boot
858 Alternatively, you can remove it from /boot/kernel/acpi.ko
859 or use the MODULES_OVERRIDE function in your kernel config
860 file and not list acpi in that list.
863 The buildworld has been fixed. You may need to install
864 the 4.x compatibility libraries for some old binaries
865 to work. Add COMPAT4X=true to your /etc/make.conf to
866 get them installed on every installworld, or execute the
867 following to get them installed only once:
868 cd src/lib/compat/compat4x.<arch>
870 You will see ``__stdoutp undefined'' until you do this.
873 There's a bug in the world build process. The cross-tools
874 are build with the NEW headers, but the OLD libc.a. This
875 leads to all kinds of problems with the new libc. A temporary
877 CFLAGS="-O -pipe -D_OLD_STDIO"
878 before building world when upgrading from 4.x to current. This
879 can be removed afterwards.
881 A proper fix to the buildworld target is needed.
884 Peter has committed his new kthread nfs client/server code.
885 NFS may be unstable after this date.
888 KSE has hit the tree. Lots of things are now different in
889 the kernel. While a few problems were introduced in the
890 initial commit, most of the major ones have been found and
894 In OLDCARD, CardBus bridges appear to be stable. The work
895 arounds described in the 20010604 entry are now no longer
896 necessary and will be ignored. Most insert/remove problems
897 have been rectified around this date.
900 named now runs as user bind and group bind rather than as
901 root. If named_enable is set to YES in /etc/rc.conf, ensure
902 that user bind is available in /etc/passwd (using vipw(8))
903 and that group bind is available in /etc/group. Also make
904 sure that user or group bind has read (and not write)
905 permission for your name server configuration and that it
906 has read and write permission for your slave zone files and
909 If you wish to continue to run named as root (a less secure
910 alternative), add a line to /etc/rc.conf saying
915 The PAM libraries have had an API upgrade that is beyond
916 the ability of the shared library major number to handle.
917 It is manifested by PAM-using ports dumping core. The
918 solution is to rebuild those ports.
921 The kernel compile module has moved from src/sys/compile/FOO
922 to src/sys/${MACHINE}/compile/FOO.
925 The pccard modem issue from 20010613 has been corrected.
926 OLDCARD support is still a little weak in -current. slot 1 is
927 known not to work on some TI based cardbus bridges. Some
928 cardbus bridges do not properly detect insert/removal events.
929 IRQ configuration needs more safety belts.
932 Softupdates problems have been corrected.
935 Peter ripped out the linkerset support. You must, as always,
936 rerun config after you cvsup if you are using the traditional
937 kernel building methods.
940 pccard modems may not work with current after 20010604 date. Some
941 do, others result in panics. *MAKE*SURE* that you update your
942 config and /etc/rc.conf ala the 20010604 entry, or you will have
943 problems (this issue will be fixed, it just hasn't been yet).
946 SOFTUPDATES seem to be broken since the middle of May or so. Do not
947 use them in current. You can disable softupdates on all mounted
948 partitions, or remove SOFTUPDATES the kernel config file.
951 After Peter's commits to the hints code, people have been noticing
952 that certain devices are attached (or try to) twice. This is due
953 to having both static hints as well as a /boot/device.hints. To
954 work around this issue, please use only one or the other mechanism
955 until this bug is fixed.
957 Please note that a feature of config is that if you have config
958 file FOO and FOO.hints, it automatically adds FOO.hints to the
959 hints.c file, whether you want it to or not.
962 Locale names have changed to match other systems better.
965 pccard support for pci cards has been committed. You must change
966 your /etc/pccard.conf irq lines. It must match the irq used by
967 pcic device. Interrupt storms may result if you fail to do this.
968 Interrupt storms look a lot like a hang.
970 You must also install a new pccardd, otherwise you will get an
971 interrupt storm at card reset time (just after it tells you what
974 pccardd_flags="-I" is necessary for the time being. It tells pccardd
975 not to ask the kernel if the interrupt is really free or not before
976 using it. You can either change the /etc/pccard.conf irq lines to
977 match pcic, or add "-i X" to the pccardd_flags.
980 INSTALL=install -C is being deprecated. If you want to do this,
981 use COPY=-C instead. The former method will be supported for only
982 a limited time. If you see
984 install: warning: the -d and -C options may not be specified together
986 in your makeworld, then you need to migrate towards using
990 It appears that vm is now stable enough to use again. However,
991 there may be other problems, so caution is still urged. alpha
992 definitely is in bad shape.
995 Minor repo damage has happened. This may cause problems
996 with cvsup of ports. If you get errors, please see
997 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
998 at the bottom for details on a workaround. The error message
1000 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
1003 Vm and/or swapping are busted on -current. Please be patient.
1006 pccard has had much reorganizational work done to it over
1007 the past few days. Everything should still work, but if
1008 not, please contact imp@freebsd.org.
1011 ata ioctl changed. Make sure to recompile both kernel and
1012 userland at the same time.
1015 New ncurses imported.
1018 DEVFS is now opt out, not opt in. Barring major problems, this
1019 will be the only way to go starting July 1.
1022 OpenSSH has been updated to 2.9. Some defaults are different,
1023 including RhostsRSAAuthentication, which changes from yes to no.
1026 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
1029 Building perl was broken at 02:25:25 PDT.
1032 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
1033 go back in the water.
1036 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
1037 this date, but before the correction date.
1040 old fsck and new kernel interactions appear to have been fixed.
1043 fsck and the kernel were changed to handle some optimizations
1044 to directory layout. This breaks backward compatibility.
1045 Update only if you understand that you must not use the old
1046 fsck with the new kernel ever.
1049 fsck has changed the meaning of the pass column in /etc/fstab.
1050 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1051 details. It is unclear if changes to /etc/fstab are necessary.
1054 portmap had changed name to rpcbind for maximum POLA in your
1055 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1056 other rpc based programs that rely on portmapper will not work
1057 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1060 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1061 and ATA_ENABLE_TAGS are no longer kernel options. They have
1062 been replaced by tunables. See ata.4 for details.
1065 The fxp driver was converted to use miibus. If you compile
1066 fxp into your kernel statically, you will need to add miibus.
1069 The wi device now defaults to BSS (infrastructure) mode
1073 /dev/urandom should be a symbolic link to /dev/random now.
1074 Users of current not using DEVFS need to run MAKEDEV std.
1075 ssh might not work if you don't.
1078 The ed driver has been updated. It now allows mii attachments,
1079 which means that you must include the miibus in your kernel if
1080 you use the ed driver.
1083 The problems with libc have been corrected. It is now mostly
1084 safe to go back into the water.
1087 The size of FILE was changed. This breaks upgrading. If
1088 you must upgrade, be prepared for pain. It also breaks almost
1089 all binaries that you've compiled on -current. You are warned
1090 that before upgrading would be a good time to do a level 0
1091 dump of your system. No, really, I mean it this time.
1093 To get to the new system, you'll need to use the following
1094 workaround. Hopefully this can be sorted out so that we
1095 don't have to move this to the updating section.
1097 To get around the installworld problem, do:
1098 # cd /usr/src/usr.bin/sed
1102 If that doesn't work, then try:
1103 # make -k installworld
1107 DEVFS is now the default. If you use vinum, make sure that you
1108 do not include devfs in your kernel as problems result.
1111 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1112 Remove them from your config.
1115 ****************************** WARNING ******************************
1116 buildkernel has been changed slightly
1117 ****************************** WARNING ******************************
1118 KERNCONF replaces the variable KERNEL for buildkernel. You
1119 should update your scripts and make.conf accordingly.
1122 config has changed to allow DEV_FOO as a replacement for NFOO.
1123 This requires a new config to build correctly.
1126 The kernel option I386_CPU is now mutually exclusive with the
1127 other cpu types. If you have an i386 system, be sure that it
1128 only had this line. Remove it for all other configurations.
1131 Changes to the kernel require it and burncd be in sync.
1134 Everyone who has hw.sndunit set to something in
1135 /etc/sysctl.conf, it is now hw.snd.unit.
1138 ex and vi were broken by some changes to sys/queue.h. If you
1139 have a bad vi, you will see make buildworld fail with a core
1140 dump while building termcap. You can work around this problem
1141 by adding -k to your make buildworld. This will cause the
1142 build to complete and install a new vi. Once that's done, you
1143 can rebuild again without the -k to pick up anything that
1144 might have been ignored by the -k option.
1146 Others have suggested that you can just rebuild libc if your
1147 vi/ex is dynamically linked, but I've not received any reports
1151 There have been some changes to libcrypt in -current. The
1152 libscrypt/libdescrypt symlink silliness is gone and the installed
1153 libcrypt is fully functional. Be aware of this.
1156 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1157 now require the addition of flag 0x80000 to their config line
1158 in pccard.conf(5). This flag is not optional. These Linksys
1159 cards will not be recognized without it.
1162 Important new FreeBSD-version stuff: PAM support has been worked
1163 in, partially from the "Unix" OpenSSH version. This requires
1164 adding the following in pam.conf:
1166 sshd auth sufficient pam_skey.so
1167 sshd auth required pam_unix.so try_first_pass
1168 sshd session required pam_permit.so
1171 cvs updated to 1.11.
1174 The random device needs more entropy, so you need to make sure
1175 that you've run mergemaster to get a /etc/rc which will seed
1176 /dev/random. If you don't and the system hangs after ldconfig,
1177 then banging on the keyboard randomly until it unhangs is one

1198 The ports tree's new layout is in place. Be sure to update
1199 your entire ports tree, or you will have problems.
1202 The perl build procedure no longer installs miniperl, nor uses
1203 the installed miniperl. It is recommended that you delete
1207 This weekend the ports tree will be updated to a new layout.
1208 It will be in an inconsistent state until noted in the UPDATING
1209 file, or with asami-san's message to the relevant mailing
1210 lists. With this new layout, you'll need to update the whole
1211 tree for anything to work.
1214 There was a change in the passwd format. Need more information.
1217 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1218 place. Please update boot loader (not the boot blocks) at the
1219 same time as your kernel.
1222 The new pmtimer device is necessary for laptops. Failure to
1223 include the device will cause suspended laptops losing time
1224 when they resume. Include
1226 in your config file and
1227 hint.pmtimer.0.at="isa"
1228 to your /boot/device.hints file.
1231 The random device has been turned into a (pseudo-)device,
1232 rather than an option. The supplied kernel config files have
1233 been updated. You will need to do something similar in your
1234 own kernel config file.
1239 If you prefer to load the loadable module, you need to do
1243 The random device module has been renamed from randomdev.ko to
1244 random.ko. You will need to edit your /boot/loader.conf to
1245 reflect this if you load this module at boot time.
1246 The line should read:
1250 The SMPNG commit has happened. It should work, but if it
1251 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
1252 to be a variety of minor issues. Please see 20000905 to make
1253 sure you don't have model loading problems which might at
1254 first blush appear related to SMP.
1257 nsswitch has been imported from NetBSD. Among other things,
1258 this means that /etc/host.conf is no longer used. See
1259 nsswitch.conf(5) instead. Note that at boot time rc.network
1260 will attempt to produce a new nsswitch.conf file for you if you
1261 don't have one, and you have host.conf.
1264 The ucred structure changed size. This breaks the interface
1265 that mountd uses. Trying to use an older mountd with a newer
1266 kernel guarantees a panic. This means that you need to use
1267 kernels newer than today only with matching mountd, but you
1268 needed to do that anyway with the boot loader changes.
1271 The boot loader has been updated. The new default kernel is
1272 now /boot/kernel/kernel.ko. The new default module location
1275 You *MUST* upgrade your boot loader and kernel at the same time.
1276 The easiest way to do this is to do the buildworld/buildkernel/
1277 installkernel/installworld dance.
1279 Furthermore, you are urged to delete your old /modules directory
1280 before booting the new kernel, since kldload will find stale
1281 modules in that directory instead of finding them in the correct
1282 path, /boot/kernel. The most common complaint that this cures
1283 is that the linux module crashes your machine after the update.
1285 if [ ! -d /boot/kernel.old ]; then
1286 mv /modules.old /boot/kernel.old
1287 chflags noschg /kernel.old
1288 mv /kernel.old /boot/kernel.old/kernel.ko
1289 chflags schg /boot/kernel.old/kernel.ko
1293 A new issue with the sendmail upgrade has come to light.
1294 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1295 incorrectly install the default aliases in /etc/mail rather than
1296 move the old one from /etc. So you'll need to manually move the
1297 file, create a symbolic link, remove the old /etc/aliases.db and
1298 run newaliases. For safety sake, you should stop sendmail
1299 while doing this and run the upgrade when locally sourced email
1300 is not likely to be generated.
1303 /boot/device.hints is now required for installkernel to
1304 succeed. You should copy GENERIC.hints for your architecture
1305 into /boot/device.hints. If and only if you compile hints
1306 into your kernel, then this file may be empty. Please note,
1307 if you have an empty or missing /boot/device.hints file and
1308 you neglected to compile hints into your kernel, no boot
1309 messages will appear after the boot loader tries to start the
1313 If you do NOT have ``options RANDOMDEV'' in your kernel and
1314 you DO want the random device then add randomdev_load="YES" to
1318 suidperl is now always built and installed on the system, but
1319 with permissions of 511. If you have applications that use
1320 this program, you are now required to add ENABLE_SUIDPERL=true
1321 to /etc/make.conf. If you forget to do this,
1322 chmod 4511 /usr/bin/suidperl
1323 will fix this until the next build.
1326 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1327 visible changes that may immediately affect your configuration
1329 - New default file locations from src/contrib/sendmail/cf/README
1330 - newaliases limited to root and trusted users
1331 - MSA port (587) turned on by default
1332 - New queue file naming system so can't go from 8.11 -> 8.9
1333 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1334 - FEATURE(`nullclient') is more full featured
1335 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1336 - mail.local FreeBSD-only -b option changed to -B
1337 - See src/contrib/sendmail/RELEASE_NOTES for more info
1340 suidperl (aka sperl) is no longer build by default. You must
1341 specifically define BUILD_SUIDPERL to "true" for it to be build.
1342 Furthermore, we recommend that you remove /usr/bin/sperl* and
1343 /usr/bin/suidperl files from your system unless you have a
1344 specific use for it.
1347 Networking defaults have been tightened. Anybody upgrading
1348 /etc/defaults/rc.conf needs to add the following lines to
1349 /etc/rc.conf if they want to have the same setup
1350 afterwards (unless the variables already are set, of course):
1351 # Enable network daemons for user convenience.
1353 portmap_enable="YES"
1354 sendmail_enable="YES"
1357 If you have null_load="YES" in your /boot/loader.conf, you
1358 will need to change that to nullfs_load="YES".
1361 The "installkernel" target has changed slightly. Now even if
1362 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1363 it will install the MYKERNEL file (built with the buildkernel
1364 target) as /kernel rather than /MYKERNEL. Those who have
1365 updated their /boot/loader.conf files to point to /MYKERNEL
1366 should remove that entry or perform manual rename of /kernel
1370 If you use CVSUP or CTM to get CVS trees, AND you used to get
1371 the old crypto files from internat.freebsd.org AND you check
1372 out files from the CVS tree with the cvs command, please read
1373 http://people.freebsd.org/~imp/internat.txt
1374 for details on potential problems that you might have and how
1377 If you are merely a mirror, or don't answer yes to each of the
1378 clauses above, you needn't worry.
1381 /etc/security has been updated to print the inode number of
1382 setuid programs that have changed. You will see a large spike
1383 in the number of changed programs the first time when you run
1384 mergemaster to get a new /etc/security.
1387 /dev/random now has good entropy collection (from the keyboard
1388 and sysmouse drivers). Please ensure that either `options
1389 RANDOMDEV' is present in your kernel config file or that
1390 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1391 not have the /dev/random driver, OpenSSL (and consequently
1392 lots of crypto tools (like SSH)) will fail with strange
1393 errors. (see below, 20000624).
1395 FreeBSD-current is safe again to run Crypto.
1398 phk made the malloc default options AJ. This may slow things
1399 down and uncover other latent bugs in the code. If you need to
1400 run at full speed, you can disable this by doing the following:
1401 ln -s aj /etc/malloc.conf
1404 libftpio's version was accidentally bumped a few days ago. This
1405 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1406 before doing your next buildworld/installworld pair. It certainly
1407 won't hurt to remove it before the update procedure. It will
1408 break fetch until a new one is built, but ftp can be used in the
1412 The crypto packages have changed for the cvsup. This has been done
1413 in a backward compatible way, but the old packages will go away at
1414 some point in the future. Look at /usr/share/examples/cvsup for
1418 With the new sys/modules/sound/drivers/*, you will need to
1419 set SYSDIR until you do an installworld after July 7th.
1422 rc.shutdown and rc will now call the rc.d scripts with start
1423 or stop. This may cause some harmless warnings from older
1424 rc.d scripts that haven't been updated.
1427 The libfetch based version of fetch has gone into the tree.
1428 Minor problems may result on some of the less popular sites,
1429 which should be reported to des@freebsd.org.
1432 From approximately this date forward, one must have the crypto
1433 system installed in order to build the system and kernel.
1434 While not technically strictly true, one should treat it as
1435 required and grab the crypto bits. If you are grabbing CVS
1436 trees, src-all and cvs-crypto should be treated as if they
1437 were required. You should check with the latest collections
1438 to make sure that these haven't changed.
1441 Mark Murray just committed the first parts of a cleanup of
1442 /dev/zero, et al. This is also cleaning up /dev/random.
1443 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1444 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1445 until Mark can merge in the fixes to this work in progress.
1446 openssh and openssl should not be used to generate keys from this
1447 date to the completion of the work.
1449 If you must operate at this reduced level of security, add '
1450 options RANDOMDEV' to your kernel or modload the randomdev
1451 module. You may also need to copy a new MAKEDEV to /dev and
1452 recreate the random and urandom devices.
1455 The license on the softupdates is now a standard 2 clause
1456 BSD license. You may need to remove your symbolic links
1457 that used to be required when updating.
1460 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1461 the config file update procedure.
1462 http://people.freebsd.org/~imp/config-upd.html
1463 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1464 isn't buildable. However, you can generate a LINT file:
1465 cd /sys/<ARCH>/conf && make LINT
1468 Binutils 2.10 have hit the tree, or will shortly. As soon
1469 as they do, the problem noted in 20000522 will be resolved and
1470 that workaround will no longer be required.
1473 phk removed the compatibility creation of wd devices in the
1474 ad driver. If you haven't done so already, you must update
1475 your fstab, etc to use the ad devices instead of the wd
1478 In addition, you'll need to update your boot blocks to a
1479 more modern version, if you haven't already done so. Modern
1480 here means 4.0 release or newer (although older releases
1484 Peter took an axe to config(8). Be sure that you read his mail
1485 on the topic before even thinking about updating. You will
1486 need to create a /boot/device.hints or add a hints directive
1487 to your config file to compile them in statically. The format
1488 of the config file has changed as well. Please see GENERIC or
1489 NEWCARD for examples of the new format.
1491 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1492 says that it has been fixed, assume that must use the hints mechanism
1493 in the loader if you need to use a machine with very old ISA cards
1497 A new set of binutils went into the tree today. Anybody
1498 building a kernel after this point is advised that they need
1499 to rebuild their binutils (or better yet do a
1500 buildworld/installworld) before building a new kernel.
1502 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1503 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1504 is recommended that you don't set this option until the problem
1508 The ethernet drivers were all updated to clean up the BPF handling.
1511 The problems with boot blocks on the alphas have been corrected.
1512 This will require some care in updating alphas. A new libstand
1513 is requires for the boot blocks to build properly.
1516 Recompile all kld modules. Proper version dependency info
1520 Modules have been disconnected from the buildworld tree and
1521 connected to the kernel building instead.
1524 You may need to build gperf
1525 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1526 when upgrading from 4.0 -> current. The build system now uses
1527 an option only in -current.
1530 The method that we brand ELF binaries has changed to be more
1531 acceptable to the binutils maintainers. You will need to
1532 rebrand your ELF binaries that aren't native. One problem
1533 binary is the Linux ldconfig. After your make world, but
1534 before you reboot, you'll need to issue:
1535 brandelf -t Linux /compat/linux/sbin/ldconfig
1536 if you have Linux compatibility enabled on your machine.
1539 If you have really bad/marginal IDE drives, you may find they
1540 don't work well. Use pio mode instead. The easiest way to
1541 cope if you have a problem combination is to add:
1542 /sbin/sysctl hw.ata.ata_dma=0
1543 to the start of /etc/rc.conf.
1546 The ISA and PCI compatibility shims have been connected to the
1547 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1548 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1549 include the appropriate option in your kernel config. Drivers
1550 using the shims should be updated or they won't ship with
1551 5.0-RELEASE, targeted for 2001.
1554 We've entered the traditional post release dumping party.
1555 Large kernel changes are being committed and are in the
1556 works. It is important to keep the systems' klds and kernel
1557 in sync as kernel interfaces and structures are changing.
1558 Before reporting kernel panics, make sure that all modules
1559 that you are loading are up to date.
1562 If you are upgrading from an older version of FreeBSD, you
1563 need to update your boot blocks as well. 'disklabel -B ad0'
1564 will do the trick. This isn't critical until you remove your
1565 wd device entries in /dev, at which point your system will not
1569 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1570 to upgrade to 4.0 from 3.x.
1576 Avoid using make -j when upgrading. From time to time in the
1577 past there have been problems using -j with buildworld and/or
1578 installworld. This is especially true when upgrading between
1579 "distant" versions (eg one that cross a major release boundary
1580 or several minor releases, or when several months have passed
1581 on the -current branch).
1583 Sometimes, obscure build problems are the result of environment
1584 poisoning. This can happen because the make utility reads its
1585 environment when searching for values for global variables.
1586 To run your build attempts in an "environmental clean room",
1587 prefix all make commands with 'env -i '. See the env(1) manual
1588 page for more details.
1592 If you are updating from a prior version of FreeBSD (even one just
1593 a few days old), you should follow this procedure. With a
1594 /usr/obj tree with a fresh buildworld,
1595 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1596 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1598 To just build a kernel when you know that it won't mess you up
1599 --------------------------------------------------------------
1600 This assumes you are already running a 5.X system. Replace
1601 ${arch} with the architecture of your machine (e.g. "i386",
1602 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1604 cd src/sys/${arch}/conf
1605 config KERNEL_NAME_HERE
1606 cd ../compile/KERNEL_NAME_HERE
1611 If this fails, go to the "To build a kernel" section.
1613 To rebuild everything and install it on the current system.

1616 # is listed here if you are upgrading from a really old current.

1632 To cross-install current onto a separate partition
1633 --------------------------------------------------
1634 # In this approach we use a separate partition to hold
1635 # current's root, 'usr', and 'var' directories. A partition
1636 # holding "/", "/usr" and "/var" should be about 2GB in

1647 ${CURRENT_ROOT}/boot/device.hints # as needed

1652 <reboot into current>
1653 <do a "native" rebuild/install as described in the previous section>
1654 <maybe install compatibility libraries from /usr/src/lib/compat>
1658 To upgrade in-place from 4.x-stable to current
1659 ----------------------------------------------
1660 # 5.x uses more space than 4.x. Also, the location of kernel
1661 # modules has changed. If you are installing 5.0 onto a 4.x
1662 # system, you'll need about 30MB of free disk space on your /
1663 # partition. If you have less than this, you may encounter difficult
1664 # to back out of problems with this procedure. If /tmp is on
1665 # the / partition, you may want to completely remove all its content
1666 # before upgrading, as this can be a common source of shortage of

1685 Make sure that you've read the UPDATING file to understand the
1686 tweaks to various things you need. At this point in the life
1687 cycle of current, things change often and you are on your own
1688 to cope. The defaults can also change, so please read ALL of
1689 the UPDATING entries.
1691 Also, if you are tracking -current, you must be subscribed to
1692 freebsd-current@freebsd.org. Make sure that before you update
1693 your sources that you have read and understood all the recent
1694 messages there. If in doubt, please track -stable which has
1695 much fewer pitfalls.
1697 [1] If you have third party modules, such as vmware, you
1698 should disable them at this point so they don't crash your
1701 [2] If you have legacy ISA devices, you may need to create
1702 your own device.hints to reflect your unique hardware
1705 [3] From the bootblocks, boot -s, and then do
1710 adjkerntz -i # if CMOS is wall time
1711 Also, when doing a major release upgrade, it is required that
1712 you boot into single user mode to do the installworld.
1713 For the 4.x -> 5.x upgrade, you will also see many messages about
1714 needing to recompile your userland. These are harmless and can
1715 be ignored while you proceed to the next step.
1717 [4] Note: This step is non-optional. Failure to do this step
1718 can result in a significant reduction in the functionality of the
1719 system. Attempting to do it by hand is not recommended and those
1720 that pursue this avenue should read this file carefully, as well
1721 as the archives of freebsd-current and freebsd-hackers mailing lists
1722 for potential gotchas.
1724 [5] Usually this step is a noop. However, from time to time
1725 you may need to do this if you get unknown user in the following
1726 step. It never hurts to do it all the time. You may need to
1727 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1728 install) after the buildworld before this step if you last updated
1729 from current before 20020224 or from -stable before 20020408.
1731 [6] 4.x boot loader can be used to boot a 5.x system, however
1732 it is difficult to do that at best. If you wish to try, then
1733 you should interrupt the boot and at the ok prompt type:
1735 ok boot /boot/kernel/kernel
1736 If this fails to work, you must install a new boot loader as
1739 [7] Before you upgrade, please make sure that you are not using
1740 compatibility slices. These are device names of the form, on i386
1741 and other architectures that use MBR slicing, /dev/ad0a without the
1742 actual slice name. Chances are excellent that these will break.
1743 You generally must update these entries to use the post FreeBSD
1744 2.x form of /dev/ad0s1a.
1746 [8] In order to have a kernel that can run the 4.x binaries
1747 needed to do an installworld, you must include the COMPAT_FREEBSD4
1748 option in your kernel. Failure to do so may leave you with a system
1749 that is hard to boot to recover.
1751 [9] When checking out sources, you must include the -P flag to have
1752 cvs prune empty directories. Also, if CPUTYPE is defined in your
1753 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1754 operator, so that buildworld can override the CPUTYPE if it needs to.
1755 In case you would like to avoid installing new packages of everything,
1756 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1757 compatibility libraries are built which should allow you to continue
1758 using your existing software for a while.
1760 [10] In order to create temporary files, /dev/random must be
1761 initialized by feeding data into it. /usr/src/etc/rc.d/preseedrandom
1765 This file contains a list, in reverse chronological order, of major
1766 breakages in tracking -current. Not all things will be listed here,
1767 and it only starts on March 15, 2000. Updating files can found in
1768 previous releases if your system is older than this.
