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 A new variable, ifi_epoch, has been added to struct if_data
28 which is part if struct ifnet. This means all network drivers
29 and network monitoring applications need to be recompiled.
32 The default configuration for the network stack has been changed
33 such that it now runs without the Giant lock unless configured
34 otherwise. If you experience network-related instability, you
35 may wish to try setting "debug.mpsafenet=0" or compiling the
36 kernel with "options NET_WITH_GIANT". Details on the netperf
37 project may be found at:
39 http://www.watson.org/~robert/freebsd/netperf/
41 Including the 20040828 announcement of configuration change
45 PFIL_HOOKS are a fixed part of the network stack now and do not
46 need to be specified in the kernel configuration file anymore.
49 Netgraph changed its message format slightly to align the data
50 portion well on 64 bit machines.
51 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
52 pppoed, bluetooth, ATM) should be recompiled when a new kernel
56 IPFW has been converted to use PFIL_HOOKS. This change is
57 transparent to userland and preserves the ipfw ABI. The ipfw
58 core packet inspection and filtering functions have not been
59 changed, only how ipfw is invoked is different. Note that
60 "option PFIL_HOOKS" is required to use IPFIREWALL compiled
61 into the kernel or as KLD.
64 The RANDOM_IP_ID option has been replaced by the sysctl
65 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
66 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
69 The size of 'struct ifnet' has changed due to the addition of the
70 if_carp placeholder. All kernel modules implementing network
71 interfaces must be recompiled as a result.
74 Module loading has been fixed. Some older installations will
75 drop proper module_path initialization and modules will fail to
76 load properly. If you have a line in /boot/loader.rc that says:
77 "initialize drop", do (i386 only):
78 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
79 chown root:wheel /boot/loader.rc
80 chmod 444 /boot/loader.rc
83 making /dev/(null|zero) into a module proved to be too unpopular,
84 so this bit has been revoked from the previous (20040801) entry.
87 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
88 so you may wish to add them to your kernel config file. See
92 System compiler has been upgraded to GCC 3.4.2-pre. As with any major
93 compiler upgrade, there are several issues to be aware of. GCC 3.4.x
94 has broken C++ ABI compatibility with previous releases yet again
95 and users will have to rebuild all their C++ programs with the new
96 compiler. If you are getting run-time error such as
97 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE"
98 This entry does apply to you.
100 A new unit-at-a-time optimization mode, which is default in this
101 compiler release, is more aggressive in removing unused static
102 symbols. This is the likely cause of 'make buildworld' breakages
103 with non-default CFLAGS where optimization level is set to -O2
106 With the upgrade of the system compiler, the kernel has been upgraded
107 to match the new system compiler. This makes it impossible to build
108 a new kernel with the old compiler. Upgrade your system via
109 make buildworld and make kernel (see below) to fix this problem.
112 The size of 'struct ifnet' has changed due to the addition of
113 the IFF_NEEDSGIANT flag (and what it implies). All kernel
114 modules implementing network interfaces must be recompiled as
118 The sound device drivers are renamed. `sound' is always required,
119 while `snd_*' should be configured accordingly to your hardware.
120 Refer to NOTES for the detail of the drivers.
123 __FreeBSD_version bumped to 502122.
126 The console initialization on Alpha has been reworked and is now
127 identical to other platforms. This means that the hardcoding of
128 the serial console and the debug port has been removed. As such,
129 hints are now required for the sio(4) driver to become a console
130 or debug port. The NO_SIO option has been decommissioned because
134 A revamp of the debugging code in the kernel with some visible
135 changes beyond just the debugging experience:
136 o The DDB option is now specific to the DDB debugger backend
137 and should not be used any more for conditional compilation
138 of debugging code for when debugging is enabled. Use the KDB
140 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
141 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
142 respectively. This is in line with the first bullet.
143 o The remote GDB support has been untangled from DDB and needs
144 to be enabled separately now. Use the GDB option for this.
145 o The GDB_REMOTE_CHAT option has been removed. Support for this
146 homegrown feature is discontinued. The GDB remote protocol
147 supports console output and it makes sense to use that.
148 o The DDB_NOKLDSYM option has been removed. The DDB debugger
149 now supports both direct symbol table lookups as well as KLD
150 symbol lookups through the linker.
153 Bluetooth code has been marked as non-i386 specific.
154 __FreeBSD_version has been bumped to 502121 to mark this change.
157 The native preemption has been added to the kernel scheduler.
158 There is some report that the ULE scheduler was broken in some
159 machines and we encourage users using the ULE scheduler either
160 stick with a known good kernel, or temporarily switch to the 4BSD
161 scheduler as a workaround.
164 The netgraph ABI version number has been incremented to indicate
165 an incompatible change in the ABI. Old netgraph nodes will refuse
166 to attach until recompiled. Netgraph now uses mbuf tags to move
167 metadata and this commit removes its home-grown metadata facility.
168 Nodes should just recompile, unless they use metadata, in which
169 case the changes are simple; the file ng_ksocket.c serves as an
170 example of such changes.
172 This also broke i4b, although the compile problem has been papered
176 ACPI has been updated to disable known-bad BIOS revisions. A message
177 will be printed on the console indicating that ACPI has been disabled
178 automatically and that the user should use a newer BIOS, if possible.
179 If you think ACPI does work on your system and want to override
180 this (i.e., for testing), set hint.acpi.0.disabled="0" at the
184 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
185 separated now. It uses the newly created "_pflogd" user/group
186 combination. If you plan to use pflogd(8) make sure to run
187 mergemaster -p or install the "_pflogd" user and group manually.
190 Network interface cloning has been overhauled. This change will
191 require a recompile of modules using cloning and modification of
192 external ones to the new API. __FreeBSD_version has been bumped
193 to 502119 to mark this change. Additionally, users creating
194 stf(4) interfaces via "ifconfig stf" will need to update their
195 scripts as this will create an interface named "stf" instead of
196 "stf0" and ifconfig will not print "stf0" to stdout.
199 On 20040524, the /etc/rc.d/nsswitch script was modified to
200 automatically create /etc/nsswitch.conf on startup if it did
201 not already exist. Unfortunately, an error in the man page
202 was carried over to the script, resulting in incorrect
203 nsswitch settings. The simplest remedy is to remove both
204 /etc/nsswitch.conf and /etc/host.conf; they will be recreated
205 during the next reboot.
208 The return value of sema_timedwait(9) has been changed to
209 make it consistent with cv_timedwait(9). Be sure to recompile
210 the ips module and any third-party modules which call
214 ALTQ is now linked to the build. This breaks ABI for struct ifnet.
215 Make sure to recompile modules and any userland that makes use of
216 sizeof(struct ifnet). In order to get the altq headers in place
217 please recompile and reinstall world.
220 Splitting kern_thread.c into 2 files (adding kern_kse.c)
221 requires that you re-run config after updating your tree.
224 The MIDI drivers have been removed. Until the new module-friendly
225 ones are merged, remove or comment out midi and seq from your
226 kernel configuration.
229 Due to a new option in ipfw (versrcreach) the ipfw(8) command
230 needs to be recompiled. Normal accept/reject rules without
231 options are not affected but those with options may break until
232 ipfw(8) is recompiled.
235 Due to changes in the callout ABI, kernels compiled after this
236 date may be incompatible with kernel modules compiled prior to
240 The PCI bus power state stuff has been turned on. If this causes
241 problems for your system, please disable it using the tunable
242 hw.pci.do_powerstate=0.
245 The bulk of the pci problems have been fixed, although the floppy
246 drive is still broken.
249 A substantial update to the pci bus resource and power management
250 have been committed. Expect a bumpy ride for a few days until
251 the unanticipated problems have been resolved.
254 Due to changes in the the Yarrow initialization process,
255 /dev/random needs to be fed before operations requiring
256 temp files can succeed in single user mode. This includes
257 running "make installworld". /dev/random may be fed by running
258 "/etc/rc.d/initrandom start" or with 20040415 source by running
259 "/etc/rc.d/preseedrandom".
262 The debug.mpsafenet tunable controls whether the kernel Giant
263 lock is held across the lower levels of the network stack, and
264 by default is turned off. In the few days following 20040322,
265 the behavior of debug.mpsafenet will change such that this
266 tunable controls Giant over all levels of the network stack.
267 If you are currently setting debug.mpsafenet to 1, you should
268 set it back to 0 (the default) again during the change-over.
269 An additional note will be added to UPDATING when sufficient
270 locking is merged to permit this to take place.
273 The FreeBSD/sparc64 platform is changing time_t from 32-bits to
274 64-bits. This is a very major incompatible change, so people
275 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
276 detailed instructions on how to make this upgrade. People
277 upgrading FreeBSD on other platforms can ignore this event.
280 The packet filter (pf) is now installed with the base system. Make
281 sure to run mergemaster -p before installworld to create required
282 user account ("proxy"). If you do not want to build pf with your
283 system you can use the NO_PF knob in make.conf.
284 Also note that pf requires "options PFIL_HOOKS" in the kernel. The
285 pf system consists of the following three devices:
287 device pflog # optional
288 device pfsync # optional
291 If you are having trouble with the libc_r -> libpthread transition
292 (see the 20040130 entry), place the following lines at the top of
295 libc_r.so.5 libpthread.so.1
296 libc_r.so libpthread.so
298 This will cause all programs and libraries linked against libc_r
299 to use libpthread instead.
302 Some sshd configuration defaults have changed: protocol version 1
303 is no longer enabled by default, and password authentication is
304 disabled by default if PAM is enabled (which it is by default).
305 OpenSSH clients should not be affected by this; other clients may
306 have to be reconfigured, upgraded or replaced.
309 The ABIs defined in <resolv.h> and <netdb.h> have been updated
310 to support improved reentrancy. Multi-threaded programs that
311 reference the "_res" or "h_errno" symbols may experience some
312 problems if they are not recompiled. Single-threaded programs
313 should remain unaffected.
316 routed has been updated in the base system from the vendor
317 sources, routed v2.27, from rhyolite.com. This change means that
318 for users who use RIP's MD5 authentication feature, FreeBSD
319 -CURRENT's routed is now incompatible with previous versions
320 of FreeBSD; however it is now compatible with implementations
321 from Sun, Cisco and other vendors.
324 The tcpcb structure has changed and makes a recompile of libkvm
325 and related userland network utilities necessary.
328 The cdevsw structure has changed in two externally visible ways.
329 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
330 Second, the d_version field must be filled in with D_VERSION.
331 Drivers outside the tree will need to be updated.
334 The /etc/rc.d/ttys script has been removed. It is no longer
335 necessary since devfs has been mandatory for some time.
338 libkse has been renamed back to libpthread and is now the
339 default threads library. The gcc -pthread option has also
340 been changed to link to libpthread instead of libc_r. For
341 alpha and sparc64 machines, libkse is not renamed and links
342 are installed so that libpthread points to libc_r. Until
343 the ports system is updated to handle this change, it is
344 recommended that folks install an /etc/libmap.conf(5) that
345 maps libc_r to libpthread. If you have any binaries or
346 libraries linked to libkse, then it is also recommended
347 that you map libkse to libpthread. Anyone that is using
348 nvidia supplied drivers and libraries should use a libmap.conf
349 that maps libpthread to libc_r since their drivers/libraries
350 do not work with libpthread.
353 ULE has entered into its probationary period as the default scheduler
354 in GENERIC. For the average user, interactivity is reported to be
355 better in many cases. On SMP machines ULE will be able to make more
356 efficient use of the available parallel resources. If you are not
357 running it now, please switch over, replacing the kernel option
358 SCHED_4BSD with SCHED_ULE.
361 Move LongRun support out of identcpu.c, where it hardly
362 belongs, into its own file and make it opt-in, not mandatory,
363 depending on CPU_ENABLE_LONGRUN config(8) option.
366 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
367 if the login process is unable to successfully set the
368 process credentials to include all groups defined for the
369 user. The current kernel limit is 16 groups; administrators
370 may wish to check that users do not have over 16 groups
371 defined, or they will be unable to log in.
374 The ACPI module has been reactivated. It is no longer required
375 to compile ACPI support into kernels statically.
378 The statfs structure has been updated with 64-bit fields to
379 allow accurate reporting of multi-terabyte filesystem
380 sizes. You should build world, then build and boot the new kernel
381 BEFORE doing a `installworld' as the new kernel will know about
382 binaries using the old statfs structure, but an old kernel will
383 not know about the new system calls that support the new statfs
385 Note that the backwards compatibility is only present when the
386 kernel is configured with the COMPAT_FREEBSD4 option. Since
387 even /bin/sh will not run with a new kernel without said option
388 you're pretty much dead in the water without it. Make sure you
389 have COMPAT_FREEBSD4!
390 Running an old kernel after a `make world' will cause programs
391 such as `df' that do a statfs system call to fail with a bad
392 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
393 that cfsd (ports/security/cfs) needs to be recompiled after
394 these changes are installed.
396 ****************************DANGER*******************************
398 DO NOT make installworld after the buildworld w/o building and
399 installing a new kernel FIRST. You will be unable to build a
400 new kernel otherwise on a system with new binaries and an old
404 Some netgraph string length constants have been changed. This
405 change requires the netgraph kernel modules and all netgraph
406 userland components to be in sync. Especially users who require
407 netgraph to boot need to make sure to have world and kernel in
408 sync before rebooting.
411 Hyperthreading logical CPU's are no longer probed by default
412 when using the MP Table. If ACPI is being used, then logical
413 CPUs will be probed if hyperthreading is enabled in the BIOS.
414 If ACPI is not being used and hyperthreading is enabled in the
415 BIOS, logical CPUs can be enabled by building a custom kernel
416 with the option MPTABLE_FORCE_HTT enabled.
419 The i386 APIC_IO kernel option has been replaced by
420 'device apic'. The ACPI module has also been temporarily
421 disabled, so ACPI must be statically compiled into your
422 kernel using 'device acpi' if you wish to use the ACPI driver.
425 The API and ABI of struct ifnet have been changed by removing
426 the if_name and if_unit members and replacing them with
427 if_xname, if_dname, and if_dunit. All network drivers and most
428 userland programs which include net/if_var.h must be updated
429 and recompiled. __FreeBSD_version has been bumped to 501113 to
433 Changes to the cdevsw default functions have been made to remove
434 the need to specify nullopen() and nullclose() explicitly.
435 __FreeBSD_version bumped to 501110.
438 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
439 mount_cd9660(8) need to be in sync with kernel.
442 Configuring a system to use IPFILTER now requires that PFIL_HOOKS
443 also be explicitly configured. Previously this dependency was
444 magically handled through some cruft in net/pfil.h; but that has
445 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
446 will fail with obtuse errors in ip_fil.c.
449 Fix a bug in arplookup(), whereby a hostile party on a locally
450 attached network could exhaust kernel memory, and cause a system
451 panic, by sending a flood of spoofed ARP requests. See
452 FreeBSD-SA-03:14.arp.
455 A change to /etc/defaults/rc.conf now causes inetd to be started
456 with `-C 60' if it is not overridden in /etc/rc.conf. This
457 causes inetd to stop accepting connections from an IP address
458 that exceeds the rate of 60 connections per minute.
461 The following rc.d scripts have been removed and should be
462 deleted from your installation: atm2.sh atm3.sh devdb
463 localdaemons network1 network2 network3. Depending on when
464 you last updated world and used mergemaster(8) you may or
465 may not have problems during the rc boot sequence. The simplest
466 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
467 The atm2.sh atm3.sh and devdb scripts were removed some time
468 ago, so depending on when you installed -CURRENT these scripts
469 may or may not exist on your system.
472 ATAng has been committed. You need to build world as sys/ata.h
473 has changed, and userland atacontrol depends on it.
474 If you use ATA SW raids you need "device ataraid" in your
475 kernel config file, as it is no longer pulled in automatically.
478 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
479 Among other things, this changes the device enumeration to be
480 closer to Solaris. Be aware that, this can even cause the machine
481 to not boot without manual intervention before the fstab is adjusted.
484 All current USB and Firewire quirks in da(4) have been deprecated
485 and will be removed for 5.2. If this causes failure for your
486 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
487 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
488 so the quirk can be re-enabled.
491 Problems with entry 20030714 have been corrected and no known issues
492 with /rescue and -j exist for host systems after this point in time.
495 FPU-less support has been removed from FreeBSD. Chances are you won't
496 notice. 386+387 support should still work after this change, but
497 it is now a minimum requirement for the i386 port that you have real
501 Some people are having problems with changes related to /rescue.
502 If you are building -j N, you will need to define NO_RESCUE. Others
503 will need to define it if /rescue has issues with their environment.
504 People should report those issues to current@.
507 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
508 across this point. Further, it might be a good idea to remove
512 Remove deprecated locale names and transition period code
513 for them, finishing switching to the new scheme. Check your
514 LANG environment variable.
517 CCD has been changed to be a fully GEOMified class. Kernel
518 and ccdconfig(8) needs to be in sync, this is particularly
519 important to remember beforehand if your source tree is on
520 a ccd device. Consider making a copy of the old ccdconfig
521 into /boot/kernel.good or wherever you keep your backup
525 There was a small window in which sed(1) was broken. If you
526 happen to have sed(1) installed during that window, which is
527 evidenced by an inability to build world with the failure
528 given below, you need to manually build and install sed(1)
529 (and only sed(1)) before doing anything else. This is a one-
530 time snafu. Typical failure mode:
532 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
533 targmatch.h:7:1: null character(s) ignored
534 targmatch.h:12:1: null character(s) ignored
535 targmatch.h:16:1: null character(s) ignored
538 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
539 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
540 usr.bin/sed/process.c).
543 Kerberos 5 (Heimdal) is now built by default. Setting
544 MAKE_KERBEROS5 no longer has any effect. If you do NOT
545 want the "base" Kerberos 5, you need to set NO_KERBEROS.
548 groff has been updated. If you try to do a buildworld and
549 get an infinite loop in troff, update to May 4th or newer. If you
550 have a newer kernel than userland, you may need to set the OSRELDATE
551 to 500110 in your environment before starting a buildworld.
554 The old rc system has been removed. Please report any problems
555 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
556 Your personal versions of these files will not be removed, so you can
557 continue to use them. However, you should take great care when updating,
558 especially when using mergemaster, since the compatibility code that
559 utilizes these old scripts has also been removed.
562 A bug has been fixed in /dev/devctl which would cause devd
563 to hang on boot, were it not for a workaround in devd. The
564 work around in devd will be removed around 20030507. You
565 have until then to upgrade your kernel before updating
566 userland. In general, you should have a userland and
567 kernel that's in sync with each other. However, given the
568 effects of this bug (hang on boot when starting devd), some
572 Alphas with libc from between 20030312 and 20030329 exhibit
573 floating point exceptions (FPEs), most notably in awk(1)
574 while upgrading the system through a buildworld.
576 So, to successfully upgrade your Alpha, you must either
577 downgrade your libc.so to a pre-20030312 version, or update
578 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
579 to CFLAGS, then forcibly rebuild and install libc:
581 cd /usr/src/lib/libc && \
582 make cleandir && make obj && \
583 make -DNOMAN -DNOPROFILE all && \
584 make -DNOMAN -DNOPROFILE install
587 sendmail 8.12.7 has been imported. It has one important
588 change for IPv6 users. The default submit.mc now uses
589 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
590 used to connect to the MTA. Users on IPv6-only machines
591 will need to edit /etc/mail/submit.mc appropriately.
594 NODEVFS option has been removed and DEVFS thereby made standard.
595 This makes all references to MAKEDEV obsolete, and they should
596 be removed when convenient.
599 The name of the device for the ofw console has changed, sparc64 users
600 must run mergemaster to update their installed /etc/ttys.
603 The scheduler framework has grown a second scheduler and consequently
604 you must specify one and only one scheduler in your kernel config.
605 The cvs config files have been updated to use the old scheduler
606 which may be selected via 'options SCHED_4BSD'. If you would like
607 to try the new, much more experimental, scheduler please try

611 A new version of the wi driver has been imported into the tree.
612 One now must have device wlan in the config file for it to operate
615 In addition, there have been some changes to how wi devices are
616 configured for point to point links to bring it more in line
617 with the former way of doing things, as well as compatibility
621 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
622 used an incompatible form of ABI for returning structures and unions
623 which FreeBSD's GCC maintainers were not aware of relative to previous
624 versions of FreeBSD. We have gone back to the ABI for now, and any
625 code compiled which is required to interoperate with other code (not
626 built at the same time) returning structs or unions should be
630 A name change in /etc/netconfig has been reverted to stay
631 compatible with suns TIRPC and also with NetBSD. You need
632 to run mergemaster after make world. A new libc does still work
633 with an outdated /etc/netconfig for some time, but you'll get
634 a warning. This warning will be removed in 20030301.
637 The recent binutils upgrade marks a kernel flag day on
638 sparc64: modules built with the old binutils will not work
639 with new kernels and vice versa. Mismatches will result in
640 panics. Make sure your kernel and modules are in sync.
643 The value of IPPROTO_DIVERT has changed. Make sure to keep
644 your kernel, netstat, natd and any third-party DIVERT
648 Old, compatibility slices have been removed in GEOM kernels.
649 This means that you will have to update your /etc/fstab to
650 not use disk devices of the form /dev/ad0a. Instead, you
651 now must specify /dev/ad0s1a, or whatever slice your FreeBSD
652 partition really is on. The old device names have gone
653 away, so if you use them anywhere else, you must also adjust
654 those uses. (This doesn't affect the disks formatted in
655 the ``dangerously-dedicated'' mode.)
658 Alphas with kernels from between 20020830 and 20021023 and/or
659 rtld (ld-elf.so.1) older than 20021023 may experience problems
660 with groff while doing a buildworld (kernel: "out of memory",
661 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
662 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
664 So, to successfully upgrade your Alpha, you must either
665 upgrade your kernel and rtld first (which might be a bit
666 tricky), or avoid running the bootstrapped groff during the
667 "transitional" buildworld. To avoid running groff during the
668 transitional upgrade run make buildworld with -DNOMAN,
669 -DNO_SHAREDOCS, and -DNO_LPR.
672 gcc has been upgraded to 3.2. It is not all binary compatible
673 with earlier versions of gcc for c++ programs. All c++
674 programs and libraries need to be recompiled.
676 Also, if you encounter g++ issues, rm /usr/include/g++/* before
677 doing an installworld to make sure that stale files are removed.
680 Our /etc/termcap now has all the entries from the XFree86 xterm
681 almost unchanged. This means xterm now supports color by default.
682 If you used TERM=xterm-color in the past you now should use
683 TERM=xterm. (xterm-color will lead to benign warnings).
686 A "bug" in gcc(1) that was hiding warning in system headers was
687 fixed. It's probably time to add -DNO_WERROR to your make line
691 COPY is being deprecated. The 20010530 change was reverted, as
692 it causes far more pain than was expected, and to always compare
693 before installing, please use INSTALL="install -C" again. The
694 -C option is now silently ignored when used with the -d option.
697 Problems with libc_r clients like KDE and GNOME have been resolved.
698 There are still some minor problems with some signals but the
699 system is stable enough for general use again. SMP is less so than UP
700 but each can successfully complete multiple buildworlds.
701 Libkvm needs to be recompiled due to KSE.
704 Now would be a bad time to upgrade. Something in or near the
705 KSE commit totally broke programs using libc_r like KDE and
709 The k5su utility installed as part of Kerberos 5 is no longer
710 installed with the set-user-ID bit set by default. Add
711 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
712 with the set-user-ID bit set.
715 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
716 Unfortunately our native GDB (at version 4.18) does not understand
717 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
718 generated debugging information for our native GDB.
721 Due to the way CVS works, it may not properly update src/contrib/gcc
722 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
723 and then do a cvs update.
726 When exec'ing set[ug]id executables, the kernel now ensures that the
727 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
730 New sendmail startup scripts have been installed to make it
731 easier to use alternative MTAs with FreeBSD. Setting the rc.conf
732 variable sendmail_enable to "NO" no longer prevents any sendmail
733 daemons from starting. Instead, either set sendmail_enable to
734 "NONE" or change mta_start_script to a script for starting
735 an alternative MTA. Setting mta_start_script to "" will
736 also prevent any MTA from being started at boot.
739 UCONSOLE is no longer a valid kernel option.
742 FreeBSD 5.0 DP-1 was basically branched today.
745 Warnings are now errors in the kernel. Unless you are a developer,
746 you should add -DNO_WERROR to your make line.
749 sendmail 8.12.2 has been imported. The sendmail binary is no
750 longer a set-user-ID root binary and the infrastructure to support
751 command line mail submission has changed. Be sure to run
752 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
753 and /etc/mail) and read /etc/mail/README for more details.
755 Due to the import of sendmail 8.12.2, a new user and group are
756 required in order for sendmail to run as a set-group-ID
757 binary. A 'make installworld' will use the new user and group
758 to set the owner and group of /var/spool/clientmqueue and will
759 fail if the new user and group do not exist. The 'smmsp' user
760 and group must be merged from src/etc/group and
761 src/etc/master.passwd before using 'make installworld'.
762 'mergemaster -p' will do this. You may need to install
763 mergemaster before this will work if you are updating from a
764 very old version of current. The updating recipe has changed
768 The preferred configuration method for PAM is now /etc/pam.d/
769 rather than /etc/pam.conf. If you have an unmodified
770 pam.conf, just delete it after your next mergemaster run. If
771 you have local modifications, you can use
772 /usr/src/etc/pam.d/convert.pl to incorporate them into your

783 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
784 started out its life in the ISDN4BSD project as an offspring
785 from sys/net/if_spppsubr.c, which eventually got a life of its
786 own. All the accumulated features and bug fixes of the i4b
787 version have now been merged back into the base system's
788 version now. The only user-visible change resulting from this
789 is that i4b's sppp(4) interfaces are to be managed with
790 spppcontrol(8) again, since ispppcontrol(8) has been retired
791 as well. (There has never been rc file support for
792 ispppcontrol in -current, but only in -stable. That will be
793 reverted by the time the changes are MFCed.)
796 The fdc(4) driver has been updated and now automatically
797 recognizes media in `standard' formats (like 1440 KB and
798 720 KB for a 3.5" high-density drive) when accessing the
799 default device node (e. g. /dev/fd0). The old variety of
800 floppy device nodes /dev/fd*.* is no longer present by
801 default, devices can be created (in DEVFS) on demand. They
802 will need to be customized then for `odd' densities using
806 The bugs in procfs' debugging support code have been fixed,
807 and truss(1) now works again.
810 Daily security checks have been split out to use the periodic(8)
811 scripts. Some change in configuration may be necessary. Please
813 http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
817 sos added VCD/SVCD support to ata driver and that needs the
818 kernel and burncd to be in sync.
821 The procfs pseudo-filesystem has now been converted to use the
822 pseudofs framework. If you have 'options PROCFS' in your
823 kernel config, you'll need to add 'options PSEUDOFS' if it's
826 This change temporarily breaks truss(1); use ktrace(1) instead
827 until the issue has been resolved.
830 A security hole in OpenSSH involving `UseLogin yes' has been
834 You need to remove /usr/obj/.../usr.bin/tip before rebuilding
835 after this date. You need to do this only once.
838 Most of the awk issues have been resolved. Some rough
839 edges may be left, but for the most part things should be
840 back to "normal." For CURRENT's usual definition of "normal."
843 Awk has been upgraded to the one true awk from bell labs. Expect
844 choppy waves in the upgrade process.
847 The asr driver problem has been resolved.
850 Due to changes in other parts of the system, the asr driver
851 now causes the system to panic on boot. Do not use it pending
852 correction. Comment it out of any kernel config file that you
853 try to use from this date forward.
856 When crossbuilding, use TARGET=xxx where you used to use
857 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
858 unless you are changing both of them. To cross build pc98 on
859 an alpha, for example, you need to set TARGET=pc98 and
863 The kernel interface that burncd depends on has changed.
864 You must recompile both the kernel and userland applications
868 When crossbuilding, please set TARGET_ARCH rather than
869 MACHINE_ARCH to indicate the target. In the future, one will
870 set TARGET_MACHINE where you set MACHINE now. At the moment,
871 setting MACHINE alone for same MACHINE_ARCH machines works
872 (eg, you can build pc98 on an i386 machine and vice versa).
875 Some weird problems result from using ACPI on some machines.
876 To disable ACPI you can add
877 hint.acpi.0.disabled="1"
878 to /boot/loader.conf (or by putting set X=Y at the boot
881 Alternatively, you can remove it from /boot/kernel/acpi.ko
882 or use the MODULES_OVERRIDE function in your kernel config
883 file and not list acpi in that list.
886 The buildworld has been fixed. You may need to install
887 the 4.x compatibility libraries for some old binaries
888 to work. Add COMPAT4X=true to your /etc/make.conf to
889 get them installed on every installworld, or execute the
890 following to get them installed only once:
891 cd src/lib/compat/compat4x.<arch>
893 You will see ``__stdoutp undefined'' until you do this.
896 There's a bug in the world build process. The cross-tools
897 are build with the NEW headers, but the OLD libc.a. This
898 leads to all kinds of problems with the new libc. A temporary
900 CFLAGS="-O -pipe -D_OLD_STDIO"
901 before building world when upgrading from 4.x to current. This
902 can be removed afterwards.
904 A proper fix to the buildworld target is needed.
907 Peter has committed his new kthread nfs client/server code.
908 NFS may be unstable after this date.
911 KSE has hit the tree. Lots of things are now different in
912 the kernel. While a few problems were introduced in the
913 initial commit, most of the major ones have been found and
917 In OLDCARD, CardBus bridges appear to be stable. The work
918 arounds described in the 20010604 entry are now no longer
919 necessary and will be ignored. Most insert/remove problems
920 have been rectified around this date.
923 named now runs as user bind and group bind rather than as
924 root. If named_enable is set to YES in /etc/rc.conf, ensure
925 that user bind is available in /etc/passwd (using vipw(8))
926 and that group bind is available in /etc/group. Also make
927 sure that user or group bind has read (and not write)
928 permission for your name server configuration and that it
929 has read and write permission for your slave zone files and
932 If you wish to continue to run named as root (a less secure
933 alternative), add a line to /etc/rc.conf saying
938 The PAM libraries have had an API upgrade that is beyond
939 the ability of the shared library major number to handle.
940 It is manifested by PAM-using ports dumping core. The
941 solution is to rebuild those ports.
944 The kernel compile module has moved from src/sys/compile/FOO
945 to src/sys/${MACHINE}/compile/FOO.
948 The pccard modem issue from 20010613 has been corrected.
949 OLDCARD support is still a little weak in -current. slot 1 is
950 known not to work on some TI based cardbus bridges. Some
951 cardbus bridges do not properly detect insert/removal events.
952 IRQ configuration needs more safety belts.
955 Softupdates problems have been corrected.
958 Peter ripped out the linkerset support. You must, as always,
959 rerun config after you cvsup if you are using the traditional
960 kernel building methods.
963 pccard modems may not work with current after 20010604 date. Some
964 do, others result in panics. *MAKE*SURE* that you update your
965 config and /etc/rc.conf ala the 20010604 entry, or you will have
966 problems (this issue will be fixed, it just hasn't been yet).
969 SOFTUPDATES seem to be broken since the middle of May or so. Do not
970 use them in current. You can disable softupdates on all mounted
971 partitions, or remove SOFTUPDATES the kernel config file.
974 After Peter's commits to the hints code, people have been noticing
975 that certain devices are attached (or try to) twice. This is due
976 to having both static hints as well as a /boot/device.hints. To
977 work around this issue, please use only one or the other mechanism
978 until this bug is fixed.
980 Please note that a feature of config is that if you have config
981 file FOO and FOO.hints, it automatically adds FOO.hints to the
982 hints.c file, whether you want it to or not.
985 Locale names have changed to match other systems better.
988 pccard support for pci cards has been committed. You must change
989 your /etc/pccard.conf irq lines. It must match the irq used by
990 pcic device. Interrupt storms may result if you fail to do this.
991 Interrupt storms look a lot like a hang.
993 You must also install a new pccardd, otherwise you will get an
994 interrupt storm at card reset time (just after it tells you what
997 pccardd_flags="-I" is necessary for the time being. It tells pccardd
998 not to ask the kernel if the interrupt is really free or not before
999 using it. You can either change the /etc/pccard.conf irq lines to
1000 match pcic, or add "-i X" to the pccardd_flags.
1003 INSTALL=install -C is being deprecated. If you want to do this,
1004 use COPY=-C instead. The former method will be supported for only
1005 a limited time. If you see
1007 install: warning: the -d and -C options may not be specified together
1009 in your makeworld, then you need to migrate towards using
1013 It appears that vm is now stable enough to use again. However,
1014 there may be other problems, so caution is still urged. alpha
1015 definitely is in bad shape.
1018 Minor repo damage has happened. This may cause problems
1019 with cvsup of ports. If you get errors, please see
1020 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
1021 at the bottom for details on a workaround. The error message
1023 Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
1026 Vm and/or swapping are busted on -current. Please be patient.
1029 pccard has had much reorganizational work done to it over
1030 the past few days. Everything should still work, but if
1031 not, please contact imp@freebsd.org.
1034 ata ioctl changed. Make sure to recompile both kernel and
1035 userland at the same time.
1038 New ncurses imported.
1041 DEVFS is now opt out, not opt in. Barring major problems, this
1042 will be the only way to go starting July 1.
1045 OpenSSH has been updated to 2.9. Some defaults are different,
1046 including RhostsRSAAuthentication, which changes from yes to no.
1049 Perl breakage in 20010501 was corrected at 14:18:33 PDT.
1052 Building perl was broken at 02:25:25 PDT.
1055 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
1056 go back in the water.
1059 A bad bug was committed at 04:48:42 PDT. Don't use kernels after
1060 this date, but before the correction date.
1063 old fsck and new kernel interactions appear to have been fixed.
1066 fsck and the kernel were changed to handle some optimizations
1067 to directory layout. This breaks backward compatibility.
1068 Update only if you understand that you must not use the old
1069 fsck with the new kernel ever.
1072 fsck has changed the meaning of the pass column in /etc/fstab.
1073 Please see the cvs commit to fsck.8 or the fsck.8 man page for
1074 details. It is unclear if changes to /etc/fstab are necessary.
1077 portmap had changed name to rpcbind for maximum POLA in your
1078 current world. /etc/hosts.{allow,deny} needs changes. nfs and
1079 other rpc based programs that rely on portmapper will not work
1080 without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
1083 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
1084 and ATA_ENABLE_TAGS are no longer kernel options. They have
1085 been replaced by tunables. See ata.4 for details.
1088 The fxp driver was converted to use miibus. If you compile
1089 fxp into your kernel statically, you will need to add miibus.
1092 The wi device now defaults to BSS (infrastructure) mode
1096 /dev/urandom should be a symbolic link to /dev/random now.
1097 Users of current not using DEVFS need to run MAKEDEV std.
1098 ssh might not work if you don't.
1101 The ed driver has been updated. It now allows mii attachments,
1102 which means that you must include the miibus in your kernel if
1103 you use the ed driver.
1106 The problems with libc have been corrected. It is now mostly
1107 safe to go back into the water.
1110 The size of FILE was changed. This breaks upgrading. If
1111 you must upgrade, be prepared for pain. It also breaks almost
1112 all binaries that you've compiled on -current. You are warned
1113 that before upgrading would be a good time to do a level 0
1114 dump of your system. No, really, I mean it this time.
1116 To get to the new system, you'll need to use the following
1117 workaround. Hopefully this can be sorted out so that we
1118 don't have to move this to the updating section.
1120 To get around the installworld problem, do:
1121 # cd /usr/src/usr.bin/sed
1125 If that doesn't work, then try:
1126 # make -k installworld
1130 DEVFS is now the default. If you use vinum, make sure that you
1131 do not include devfs in your kernel as problems result.
1134 FFS_ROOT and CD9660_ROOT have been removed or deprecated.
1135 Remove them from your config.
1138 ****************************** WARNING ******************************
1139 buildkernel has been changed slightly
1140 ****************************** WARNING ******************************
1141 KERNCONF replaces the variable KERNEL for buildkernel. You
1142 should update your scripts and make.conf accordingly.
1145 config has changed to allow DEV_FOO as a replacement for NFOO.
1146 This requires a new config to build correctly.
1149 The kernel option I386_CPU is now mutually exclusive with the
1150 other cpu types. If you have an i386 system, be sure that it
1151 only had this line. Remove it for all other configurations.
1154 Changes to the kernel require it and burncd be in sync.
1157 Everyone who has hw.sndunit set to something in
1158 /etc/sysctl.conf, it is now hw.snd.unit.
1161 ex and vi were broken by some changes to sys/queue.h. If you
1162 have a bad vi, you will see make buildworld fail with a core
1163 dump while building termcap. You can work around this problem
1164 by adding -k to your make buildworld. This will cause the
1165 build to complete and install a new vi. Once that's done, you
1166 can rebuild again without the -k to pick up anything that
1167 might have been ignored by the -k option.
1169 Others have suggested that you can just rebuild libc if your
1170 vi/ex is dynamically linked, but I've not received any reports
1174 There have been some changes to libcrypt in -current. The
1175 libscrypt/libdescrypt symlink silliness is gone and the installed
1176 libcrypt is fully functional. Be aware of this.
1179 Linksys Fast Ethernet PCCARD cards supported by the ed driver
1180 now require the addition of flag 0x80000 to their config line
1181 in pccard.conf(5). This flag is not optional. These Linksys
1182 cards will not be recognized without it.
1185 Important new FreeBSD-version stuff: PAM support has been worked
1186 in, partially from the "Unix" OpenSSH version. This requires
1187 adding the following in pam.conf:
1189 sshd auth sufficient pam_skey.so
1190 sshd auth required pam_unix.so try_first_pass
1191 sshd session required pam_permit.so
1194 cvs updated to 1.11.
1197 The random device needs more entropy, so you need to make sure
1198 that you've run mergemaster to get a /etc/rc which will seed
1199 /dev/random. If you don't and the system hangs after ldconfig,
1200 then banging on the keyboard randomly until it unhangs is one

1222 your entire ports tree, or you will have problems.
1225 The perl build procedure no longer installs miniperl, nor uses
1226 the installed miniperl. It is recommended that you delete
1230 This weekend the ports tree will be updated to a new layout.
1231 It will be in an inconsistent state until noted in the UPDATING
1232 file, or with asami-san's message to the relevant mailing
1233 lists. With this new layout, you'll need to update the whole
1234 tree for anything to work.
1237 There was a change in the passwd format. Need more information.
1240 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
1241 place. Please update boot loader (not the boot blocks) at the
1242 same time as your kernel.
1245 The new pmtimer device is necessary for laptops. Failure to
1246 include the device will cause suspended laptops losing time
1247 when they resume. Include
1249 in your config file and
1250 hint.pmtimer.0.at="isa"
1251 to your /boot/device.hints file.
1254 The random device has been turned into a (pseudo-)device,
1255 rather than an option. The supplied kernel config files have
1256 been updated. You will need to do something similar in your
1257 own kernel config file.

1276 sure you don't have model loading problems which might at
1277 first blush appear related to SMP.
1280 nsswitch has been imported from NetBSD. Among other things,
1281 this means that /etc/host.conf is no longer used. See
1282 nsswitch.conf(5) instead. Note that at boot time rc.network
1283 will attempt to produce a new nsswitch.conf file for you if you
1284 don't have one, and you have host.conf.
1287 The ucred structure changed size. This breaks the interface
1288 that mountd uses. Trying to use an older mountd with a newer
1289 kernel guarantees a panic. This means that you need to use
1290 kernels newer than today only with matching mountd, but you
1291 needed to do that anyway with the boot loader changes.
1294 The boot loader has been updated. The new default kernel is
1295 now /boot/kernel/kernel.ko. The new default module location
1298 You *MUST* upgrade your boot loader and kernel at the same time.
1299 The easiest way to do this is to do the buildworld/buildkernel/
1300 installkernel/installworld dance.
1302 Furthermore, you are urged to delete your old /modules directory
1303 before booting the new kernel, since kldload will find stale
1304 modules in that directory instead of finding them in the correct
1305 path, /boot/kernel. The most common complaint that this cures
1306 is that the linux module crashes your machine after the update.
1308 if [ ! -d /boot/kernel.old ]; then
1309 mv /modules.old /boot/kernel.old
1310 chflags noschg /kernel.old
1311 mv /kernel.old /boot/kernel.old/kernel.ko
1312 chflags schg /boot/kernel.old/kernel.ko
1316 A new issue with the sendmail upgrade has come to light.
1317 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will
1318 incorrectly install the default aliases in /etc/mail rather than
1319 move the old one from /etc. So you'll need to manually move the
1320 file, create a symbolic link, remove the old /etc/aliases.db and
1321 run newaliases. For safety sake, you should stop sendmail
1322 while doing this and run the upgrade when locally sourced email
1323 is not likely to be generated.
1326 /boot/device.hints is now required for installkernel to
1327 succeed. You should copy GENERIC.hints for your architecture
1328 into /boot/device.hints. If and only if you compile hints
1329 into your kernel, then this file may be empty. Please note,
1330 if you have an empty or missing /boot/device.hints file and
1331 you neglected to compile hints into your kernel, no boot
1332 messages will appear after the boot loader tries to start the
1336 If you do NOT have ``options RANDOMDEV'' in your kernel and
1337 you DO want the random device then add randomdev_load="YES" to
1341 suidperl is now always built and installed on the system, but
1342 with permissions of 511. If you have applications that use
1343 this program, you are now required to add ENABLE_SUIDPERL=true
1344 to /etc/make.conf. If you forget to do this,
1345 chmod 4511 /usr/bin/suidperl
1346 will fix this until the next build.
1349 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
1350 visible changes that may immediately affect your configuration
1352 - New default file locations from src/contrib/sendmail/cf/README
1353 - newaliases limited to root and trusted users
1354 - MSA port (587) turned on by default
1355 - New queue file naming system so can't go from 8.11 -> 8.9
1356 - FEATURE(`rbl') renamed to FEATURE(`dnsbl')
1357 - FEATURE(`nullclient') is more full featured
1358 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
1359 - mail.local FreeBSD-only -b option changed to -B
1360 - See src/contrib/sendmail/RELEASE_NOTES for more info
1363 suidperl (aka sperl) is no longer build by default. You must
1364 specifically define BUILD_SUIDPERL to "true" for it to be build.
1365 Furthermore, we recommend that you remove /usr/bin/sperl* and
1366 /usr/bin/suidperl files from your system unless you have a
1367 specific use for it.
1370 Networking defaults have been tightened. Anybody upgrading
1371 /etc/defaults/rc.conf needs to add the following lines to
1372 /etc/rc.conf if they want to have the same setup
1373 afterwards (unless the variables already are set, of course):
1374 # Enable network daemons for user convenience.
1376 portmap_enable="YES"
1377 sendmail_enable="YES"
1380 If you have null_load="YES" in your /boot/loader.conf, you
1381 will need to change that to nullfs_load="YES".
1384 The "installkernel" target has changed slightly. Now even if
1385 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
1386 it will install the MYKERNEL file (built with the buildkernel
1387 target) as /kernel rather than /MYKERNEL. Those who have
1388 updated their /boot/loader.conf files to point to /MYKERNEL
1389 should remove that entry or perform manual rename of /kernel
1393 If you use CVSUP or CTM to get CVS trees, AND you used to get
1394 the old crypto files from internat.freebsd.org AND you check
1395 out files from the CVS tree with the cvs command, please read
1396 http://people.freebsd.org/~imp/internat.txt
1397 for details on potential problems that you might have and how
1400 If you are merely a mirror, or don't answer yes to each of the
1401 clauses above, you needn't worry.
1404 /etc/security has been updated to print the inode number of
1405 setuid programs that have changed. You will see a large spike
1406 in the number of changed programs the first time when you run
1407 mergemaster to get a new /etc/security.
1410 /dev/random now has good entropy collection (from the keyboard
1411 and sysmouse drivers). Please ensure that either `options
1412 RANDOMDEV' is present in your kernel config file or that
1413 `randomdev_load="YES"' is in your /boot/loader.conf. If you do
1414 not have the /dev/random driver, OpenSSL (and consequently
1415 lots of crypto tools (like SSH)) will fail with strange
1416 errors. (see below, 20000624).
1418 FreeBSD-current is safe again to run Crypto.
1421 phk made the malloc default options AJ. This may slow things
1422 down and uncover other latent bugs in the code. If you need to
1423 run at full speed, you can disable this by doing the following:
1424 ln -s aj /etc/malloc.conf
1427 libftpio's version was accidentally bumped a few days ago. This
1428 has been corrected. You may need to remove /usr/lib/libftpio.so.6
1429 before doing your next buildworld/installworld pair. It certainly
1430 won't hurt to remove it before the update procedure. It will
1431 break fetch until a new one is built, but ftp can be used in the
1435 The crypto packages have changed for the cvsup. This has been done
1436 in a backward compatible way, but the old packages will go away at
1437 some point in the future. Look at /usr/share/examples/cvsup for
1441 With the new sys/modules/sound/drivers/*, you will need to
1442 set SYSDIR until you do an installworld after July 7th.
1445 rc.shutdown and rc will now call the rc.d scripts with start
1446 or stop. This may cause some harmless warnings from older
1447 rc.d scripts that haven't been updated.
1450 The libfetch based version of fetch has gone into the tree.
1451 Minor problems may result on some of the less popular sites,
1452 which should be reported to des@freebsd.org.
1455 From approximately this date forward, one must have the crypto
1456 system installed in order to build the system and kernel.
1457 While not technically strictly true, one should treat it as
1458 required and grab the crypto bits. If you are grabbing CVS
1459 trees, src-all and cvs-crypto should be treated as if they
1460 were required. You should check with the latest collections
1461 to make sure that these haven't changed.
1464 Mark Murray just committed the first parts of a cleanup of
1465 /dev/zero, et al. This is also cleaning up /dev/random.
1466 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
1467 -CURRENT FROM THIS POINT to 2000710 for cryptographic services
1468 until Mark can merge in the fixes to this work in progress.
1469 openssh and openssl should not be used to generate keys from this
1470 date to the completion of the work.
1472 If you must operate at this reduced level of security, add '
1473 options RANDOMDEV' to your kernel or modload the randomdev
1474 module. You may also need to copy a new MAKEDEV to /dev and
1475 recreate the random and urandom devices.
1478 The license on the softupdates is now a standard 2 clause
1479 BSD license. You may need to remove your symbolic links
1480 that used to be required when updating.
1483 Scott Flatman <sf@aracnet.com> sent in a decent write-up on
1484 the config file update procedure.
1485 http://people.freebsd.org/~imp/config-upd.html
1486 NOTE: LINT is gone. It has been replaced with NOTES. NOTES
1487 isn't buildable. However, you can generate a LINT file:
1488 cd /sys/<ARCH>/conf && make LINT
1491 Binutils 2.10 have hit the tree, or will shortly. As soon
1492 as they do, the problem noted in 20000522 will be resolved and
1493 that workaround will no longer be required.
1496 phk removed the compatibility creation of wd devices in the
1497 ad driver. If you haven't done so already, you must update
1498 your fstab, etc to use the ad devices instead of the wd
1501 In addition, you'll need to update your boot blocks to a
1502 more modern version, if you haven't already done so. Modern
1503 here means 4.0 release or newer (although older releases
1507 Peter took an axe to config(8). Be sure that you read his mail
1508 on the topic before even thinking about updating. You will
1509 need to create a /boot/device.hints or add a hints directive
1510 to your config file to compile them in statically. The format
1511 of the config file has changed as well. Please see GENERIC or
1512 NEWCARD for examples of the new format.
1514 Indirectly, this also breaks USERCONFIG. Unless a newer entry
1515 says that it has been fixed, assume that must use the hints mechanism
1516 in the loader if you need to use a machine with very old ISA cards
1520 A new set of binutils went into the tree today. Anybody
1521 building a kernel after this point is advised that they need
1522 to rebuild their binutils (or better yet do a
1523 buildworld/installworld) before building a new kernel.
1525 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
1526 or MALLOC_OPTIONS env var) J will cause ld to dump core. It
1527 is recommended that you don't set this option until the problem
1531 The ethernet drivers were all updated to clean up the BPF handling.
1534 The problems with boot blocks on the alphas have been corrected.
1535 This will require some care in updating alphas. A new libstand
1536 is requires for the boot blocks to build properly.
1539 Recompile all kld modules. Proper version dependency info
1543 Modules have been disconnected from the buildworld tree and
1544 connected to the kernel building instead.
1547 You may need to build gperf
1548 cd /usr/src/gnu/usr.bin/gperf && make depend all install
1549 when upgrading from 4.0 -> current. The build system now uses
1550 an option only in -current.
1553 The method that we brand ELF binaries has changed to be more
1554 acceptable to the binutils maintainers. You will need to
1555 rebrand your ELF binaries that aren't native. One problem
1556 binary is the Linux ldconfig. After your make world, but
1557 before you reboot, you'll need to issue:
1558 brandelf -t Linux /compat/linux/sbin/ldconfig
1559 if you have Linux compatibility enabled on your machine.
1562 If you have really bad/marginal IDE drives, you may find they
1563 don't work well. Use pio mode instead. The easiest way to
1564 cope if you have a problem combination is to add:
1565 /sbin/sysctl hw.ata.ata_dma=0
1566 to the start of /etc/rc.conf.
1569 The ISA and PCI compatibility shims have been connected to the
1570 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
1571 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
1572 include the appropriate option in your kernel config. Drivers
1573 using the shims should be updated or they won't ship with
1574 5.0-RELEASE, targeted for 2001.
1577 We've entered the traditional post release dumping party.
1578 Large kernel changes are being committed and are in the
1579 works. It is important to keep the systems' klds and kernel
1580 in sync as kernel interfaces and structures are changing.
1581 Before reporting kernel panics, make sure that all modules
1582 that you are loading are up to date.
1585 If you are upgrading from an older version of FreeBSD, you
1586 need to update your boot blocks as well. 'disklabel -B ad0'
1587 will do the trick. This isn't critical until you remove your
1588 wd device entries in /dev, at which point your system will not
1592 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
1593 to upgrade to 4.0 from 3.x.
1597 # NOTE: 5.x below applies to 6.0-currrent as well, for the
1598 # momemnt. 4.any -> 5.any upgrade support will remain in
1599 # place for 6.0 current, but after 5.3 RELEASE, the 4.any ->
1600 # 6.0-current upgrade path will require moving through 5.3
1605 Avoid using make -j when upgrading. From time to time in the
1606 past there have been problems using -j with buildworld and/or
1607 installworld. This is especially true when upgrading between
1608 "distant" versions (eg one that cross a major release boundary
1609 or several minor releases, or when several months have passed
1610 on the -current branch).
1612 Sometimes, obscure build problems are the result of environment
1613 poisoning. This can happen because the make utility reads its
1614 environment when searching for values for global variables.
1615 To run your build attempts in an "environmental clean room",
1616 prefix all make commands with 'env -i '. See the env(1) manual
1617 page for more details.
1621 If you are updating from a prior version of FreeBSD (even one just
1622 a few days old), you should follow this procedure. With a
1623 /usr/obj tree with a fresh buildworld,
1624 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1625 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1627 To just build a kernel when you know that it won't mess you up
1628 --------------------------------------------------------------
1629 This assumes you are already running a 5.X system. Replace
1630 ${arch} with the architecture of your machine (e.g. "i386",
1631 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
1633 cd src/sys/${arch}/conf
1634 config KERNEL_NAME_HERE
1635 cd ../compile/KERNEL_NAME_HERE
1640 If this fails, go to the "To build a kernel" section.
1642 To rebuild everything and install it on the current system.

1660 To cross-install current onto a separate partition
1661 --------------------------------------------------
1662 # In this approach we use a separate partition to hold
1663 # current's root, 'usr', and 'var' directories. A partition
1664 # holding "/", "/usr" and "/var" should be about 2GB in

1686 To upgrade in-place from 4.x-stable to current
1687 ----------------------------------------------
1688 # 5.x uses more space than 4.x. Also, the location of kernel
1689 # modules has changed. If you are installing 5.0 onto a 4.x
1690 # system, you'll need about 30MB of free disk space on your /
1691 # partition. If you have less than this, you may encounter difficult
1692 # to back out of problems with this procedure. If /tmp is on
1693 # the / partition, you may want to completely remove all its content

1713 Make sure that you've read the UPDATING file to understand the
1714 tweaks to various things you need. At this point in the life
1715 cycle of current, things change often and you are on your own
1716 to cope. The defaults can also change, so please read ALL of
1717 the UPDATING entries.
1719 Also, if you are tracking -current, you must be subscribed to
1720 freebsd-current@freebsd.org. Make sure that before you update
1721 your sources that you have read and understood all the recent
1722 messages there. If in doubt, please track -stable which has
1723 much fewer pitfalls.
1725 [1] If you have third party modules, such as vmware, you
1726 should disable them at this point so they don't crash your
1729 [2] If you have legacy ISA devices, you may need to create
1730 your own device.hints to reflect your unique hardware
1733 [3] From the bootblocks, boot -s, and then do
1738 adjkerntz -i # if CMOS is wall time
1739 Also, when doing a major release upgrade, it is required that
1740 you boot into single user mode to do the installworld.
1741 For the 4.x -> 5.x upgrade, you will also see many messages about
1742 needing to recompile your userland. These are harmless and can
1743 be ignored while you proceed to the next step.
1745 [4] Note: This step is non-optional. Failure to do this step
1746 can result in a significant reduction in the functionality of the
1747 system. Attempting to do it by hand is not recommended and those
1748 that pursue this avenue should read this file carefully, as well
1749 as the archives of freebsd-current and freebsd-hackers mailing lists
1750 for potential gotchas.
1752 [5] Usually this step is a noop. However, from time to time
1753 you may need to do this if you get unknown user in the following
1754 step. It never hurts to do it all the time. You may need to
1755 install a new mergemaster (cd src/usr.sbin/mergemaster && make
1756 install) after the buildworld before this step if you last updated
1757 from current before 20020224 or from -stable before 20020408.
1759 [6] 4.x boot loader can be used to boot a 5.x system, however
1760 it is difficult to do that at best. If you wish to try, then
1761 you should interrupt the boot and at the ok prompt type:
1763 ok boot /boot/kernel/kernel
1764 If this fails to work, you must install a new boot loader as
1767 [7] Before you upgrade, please make sure that you are not using
1768 compatibility slices. These are device names of the form, on i386
1769 and other architectures that use MBR slicing, /dev/ad0a without the
1770 actual slice name. Chances are excellent that these will break.
1771 You generally must update these entries to use the post FreeBSD
1772 2.x form of /dev/ad0s1a.
1774 [8] In order to have a kernel that can run the 4.x binaries
1775 needed to do an installworld, you must include the COMPAT_FREEBSD4
1776 option in your kernel. Failure to do so may leave you with a system
1777 that is hard to boot to recover.
1779 [9] When checking out sources, you must include the -P flag to have
1780 cvs prune empty directories. Also, if CPUTYPE is defined in your
1781 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment
1782 operator, so that buildworld can override the CPUTYPE if it needs to.
1783 In case you would like to avoid installing new packages of everything,
1784 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
1785 compatibility libraries are built which should allow you to continue
1786 using your existing software for a while.
1788 [10] In order to create temporary files, /dev/random must be
1789 initialized by feeding data into it. src/etc/rc.d/preseedrandom
1793 This file contains a list, in reverse chronological order, of major
1794 breakages in tracking -current. Not all things will be listed here,
1795 and it only starts on March 15, 2000. Updating files can found in
1796 previous releases if your system is older than this.
