UPDATING
Updating Information for FreeBSD STABLE users
This file is maintained by imp@village.org. Please send new entries
directly to him. See end of file for further details. A reverse
chronology since 4.0 was released is included, followed by the common
items quick how-tos, followed by entries for versions of -current
prior to 4.0 Release.
20000803:
The "installkernel" target has changed slightly. Now even if
you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL'
it will install the MYKERNEL file (built with the buildkernel
target) as /kernel rather than /MYKERNEL. Those who have
updated their /boot/loader.conf files to point to /MYKERNEL
should remove that entry or perform manual rename of /kernel
to /MYKERNEL.
20000724:
FreeBSD 4.1 Released on or about this date.
20000711:
If you use CVSUP or CTM to get CVS trees, AND you used to get
the old crypto files from internat.freebsd.org AND you check
out files from the CVS tree with the cvs command, please read
http://people.freebsd.org/~imp/internat.txt
for details on potential problems that you might have and how
to get around them.
If you are merely a mirror, or don't answer yes to each of the
clauses above, you needn't worry.
20000707:
We started building modules here. IF you don't wish to
follow the documented proceedure for building kernels, then
you'll have to install new mk files from src/share/mk, or
define NO_MODULES.
20000706:
Binutils were updated. In order to build a kernel after this
date, you must follow the updating procedure for building
kernels exactly as presented here. You may be able to get away
with doing it the old way, but if it breaks, make sure that you've
tried the "To build a kernel" section with a fresh /usr/obj
first.
20000622:
The license on the softupdates is now a standard 2 clause
BSD license. You may need to remove your symbolic links
that used to be required when updating.
20000501:
At approximately this date, an incompatible kernel change
was made which means that if you update kernels accross
this boundary, you also have to update modules, and vice
versa.
20000315:
FreeBSD 4.0 RELEASE. Historical entries follow the common
items.
****************************** 4.0 RELEASE ******************************
COMMON ITEMS:
To build a kernel
-----------------
cd /usr/src
# If you have not already done so, please buildworld here
# You will also need to update your config file to 4.x. Usually
# people tend to start with GENERIC from 4.x and hack from there.
make buildkernel KERNEL=<YOUR_KERNEL_HERE>
make installkernel KERNEL=<YOUR_KERNEL_HERE>
# Verify that the new kernel works, it will be installed as
# /kernel
To rebuild disk /dev entries
----------------------------
MAKEDEV should be copied from src/etc/MAKEDEV to /dev before
starting the following:
For N in the list of disks
MAKEDEV N # eg ad0
for M in the list of slices
MAKEDEV NsMa # eg ad0s1a
To rebuild everything
---------------------
make world
Except when it doesn't work :-)
To update from 3.x to 4.x stable
--------------------------------
***********************************************************
READ -STABLE ARCHIVES FOR THE LAST WEEK OR TWO BEFORE
STARTING THIS PROCESS. UPDATING MAY LAG BEHIND A LITTLE
A GOTCHAS ARE OFTEN REPORTED IN FREEBSD-STABLE@FREEBSD.ORG
BEFORE BEING INCLUDED HERE. IF YOU ARE GOING TO DO REMOTE
MACHINES, MAKE SURE THAT THE EXACT VERSION YOU ARE UPDATING
THEM TO WORKS ON LOCAL MACHINES BEFORE PROCEEDING.
***********************************************************
<see notes below> [3]
cd /usr/src
<see notes below> [2]
make buildworld
<follow directions to build/install a kernel>
cd /usr/src/sbin/mknod
make install
<follow rebuild disk /dev entries above> [1]
reboot
<in single user>
cd /usr/src
cd gnu/usr.bin/texinfo/install-info
make install
cd ../../../..
ldconfig -R /usr/obj/usr/src/lib/libc
make installworld [5]
mergemaster [4]
reboot
<multi-user>
[1] You may need to switch from wd to ad ala 19991210. In
addition, you should disable any third party modules such as
vmware so that you don't crash your system on reboot.
[2] If you have any of the following in your /etc/make.conf,
please comment them out before following these instructions
and then do a make buildworld + make installworld after you
are back to <multi-user> above:
MAKE_KERBEROS4
[3] Update to 4.x-stable sources. Make sure that you get all
the parts. If you are using cvsup files that are older than a
couple of months, be sure they have all the components listed
in /usr/share/examples/cvsup. Crypto and secure are now
required.
[4] This step is optional, but is generally a good idea. If
you wish to use many of the new features in 4.x, you must do
this anyway.
To update from 4.0-RELEASE or later to the most current
4.x-STABLE
----------
make buildworld
make buildkernel KERNEL=YOUR_KERNEL_HERE
make installkernel KERNEL=YOUR_KERNEL_HERE
reboot (in single user) [1]
make installworld
reboot
[1] You can often get away without doing this step as the
system will be properly updated. During the running of the
installworld, however, system components may break and other
oddities may happen. Don't do this on systems that aren't
otherwise quiet as unpredictable results may happen. If in
doubt, reboot into single user. For remote installs, keep
a separate kernel around and use a serial console if at all
possible.
What follows are older entries for those people upgrading from earlier
versions of -stable/-current.
20000308:
The binary interface of perl to its modules changed. You
will need to recompile any perl moudles after an
installworld. This includes all ports matching the pattern
/usr/ports/*/p5-*.
20000303:
CMSG_XXX macros offset in <sys/socket.h> has changed to
conform RFC-2292. All affected applications have been
corrected. The i386 platform's offsets haven't changed, but
the alpha's did. When you build and install new kernel on
FreeBSD/alpha, you must also do a make world.
20000225:
OpenSSH has been added to FreeBSD. This may conflict with the
ports/security/ssh port since it installs binaries into
/usr/bin and the port goes into /usr/local/bin. Most paths
have /usr/bin in the path before /usr/local/bin, so problems
may arise. If you don't want OpenSSH, add NO_OPENSSH=yes to
your make.conf.
You will also need to enable OpenSSH in /etc/rc.conf if you
want to run the new servers. You may need to move your host
key and other config files from /usr/local/etc to /etc/ssh.
OpenSSH's command line parsing, available options and default
settings aren't the same as ssh, so some care needs to be
taken in its operation. One should do a full audit of all
configuration settings.
20000205:
The xinstall problem has kinda sorta been corrected. The
following is known to work by the author of UPDATING. It
is what he did to update his laptop. It is likely the same
effect as the work around listed in 20000129.
make buildworld
make installworld This will fail
cd usr.bin/xinstall
make clean all install NOSHARED=YES
cd ../..
make installworld
If it doesn't work for you, then I'm sure that there will be
another 100 messages in -current.
20000204:
libipsec version number changed from 2 to 0. The original
commit of Jan 6 incorrectly set this to 2. Remove
/usr/lib/libipsec.so.2* before the buildworld and rebuild
anything that uses libipsec.so after you install the new
version.
20000201:
The rcmd related functions have been aligned with other BSD
implementations. rlogind and rshd have been changed to use
the new API. A make world is recommended to keep them in sync
with the libraries they use.
http://www.FreeBSD.org/cgi/cvsweb.cgi/src/lib/libc/net/rcmd.c
has the details.
20000129:
{set,get}flags have been added to the tree for rather dubious
reasons.
IF AND ONLY IF installworld fails:
make -k -DNOFSCHG installworld
make installworld
This issue was resolved Feb 5, 2000.
20000125:
rcmd_af() is added for multiple address family support. rsh
and rlogin have been updated to use this to support INET6. A
make world is recommended to keep them in sync with the
libraries they use.
20000124:
The default way that virtual tables in our default C++
compiler has changed. We used to use THUNKS for virtual
inheritance. Unfortunately there are bugs that The GCC
developers thought would be fixed in GCC 2.95. However it
isn't.
After this change existing applications written in C++ may
give errors like below when you try to run them:
/usr/libexec/ld-elf.so.1: /usr/lib/libstdc++.so.3: Undefined symbol "__vt_7filebuf"
The only fix is to rebuild the application and any C++
libraries used.
20000124:
The management of next_writeable has been move from the
kernel to userspace. This means that the burncd command
must be in sync with the kernel. So make world is your
friend.
20000117:
GNU texinfo upgraded to 4.0. It is recommended that you use
make buildworld to update.
20000117:
CAM_VERSION has been increased. Recompile all programs that
depend on it (tosha, camcontrol, etc) when moving to kernels
past this date.
20000115:
pccard ioctls changed with a commit to have the kernel tell
pccardd which device it created, rather than having pccardd
dictate it to the kernel. Recompile kernel and
pccardd/pccardc together. pccardd/pccardc rely on a kernel
Makefile that must be installed prior to building them. Make
world will automatically take care of this issue, but you need
to know if you are building by hand.
20000109:
Your kernel config files need to be changed to s/controller/device/
in them. You will need a new version of config to do this.
20000107:
chown & chgrp moved again
This is a heads up to let you know that you need to
rm -f /sbin/chown /bin/chgrp
after your next `make world'. Additionally you need to install
a new /dev/MAKEDEV (mergemaster(8) will assist you in this).
20000107:
SHA-1 password support gone
As warned yesterday, I've just removed the ability for
libcrypt to understand SHA-1 passwords. This was present but
undocumented in the tree for the past few months and was
removed so it can be reimplemented properly as part of a
revamped libcrypt at a later date. Anyone who was actually
making use of the feature will have to update their passwords
back to MD5 before they reinstall the library.
20000106:
ioctl numbers changed for dvdio ioctls. You will need to recompile
anything that uses them. wormcontrol has been deprecated in
favor of burncd.
19991223:
Building linux and svr4 compatibility into the kernel now
requires /usr/bin/genassym. Go to /usr/src/usr.bin/genassym,
do "make obj ; make clean depend all install" before building
your kernel.
19991218:
sendmail.cf has moved from /etc/sendmail.cf to
/etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf
and /etc/rc to cope as well as moving sendmail.cf.
19991216:
ntp 4.0.98 has replaced the ancient xntpd. The daemon name
changed from xntpd to ntpd, so you may need to update your
/etc/rc.conf file. The ntp.conf files are compatible with the
old release, unless you are using a local reference clock.
Details about ntp4 can be found at http://www.ntp.org/.
xntpd will be cvs removed from the repo in about a week.
19991213:
Soren updated the ata driver. Please update to at least this
version before submitting bug reports.
19991210:
The ata driver has become the primary ata/ide/atapi driver in
the kernel. The wd driver is obsolete. You should upgrade your
machine to the new ata driver. You will need to follow the
directions for updating the devices in the 19991205 entry. You
will need to update all occurances of wd to ad in your config files
(/etc/rc.conf, /etc/fstab, etc). A compatibility device exists
for wd for the time being, but once you have determined that
ata is working for you, transition to the new ad devices.
19991205:
Block devices are going away. You will need to update your /dev
tree with a fresh copy of MAKEDEV for things to always work in
the future. fsck is unable to cope with dirty file systems
after this change, so it may work for you or it may not.
See "To rebuild disk /dev entries" at the end of the file.
*** All uses of block devices must be converted to char devices.
*** Likely the only thing impacted is dumpdev in /etc/rc.conf
19991204:
The dc interface has replaced al, ax, dm, pn and mx. The former
have been removed.
19991204:
Support for the old 'sd' device names has been removed in
favor of 'da'. Please update your /etc/fstab, /etc/rc.conf
and any other places you might have sd names cached.
Generally these changes are as simple as s=/dev/sd=/dev/da=g,
but be careful to make sure that things are really that
simple. You may also need to create /dev entries for the da
devices as well.
See "To rebuild disk /dev entries" at the end of the file.
19991203:
BAD144 support has been removed. Cope or replace the hardware.
19991129:
ALPHA users take note. All klds will need to be recompiled for
kernels build after this date. It is a good time to update since
pal.s will be going away soon.
19991126:
MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and
MD_ROOT_SIZE options in the md driver. md driver now deals with
the hacks. You should add md driver to kerneles that have
MFS_ROOT, et al. See GENERIC or LINT for details.
19991125:
The ep changed a while ago and can no longer be used with hard
wired addresses in the config file.
19991122:
The bridge drivers for sound cards have been committed. Please
see LINT for instructions for your card, if it still works at
all.
19991113:
Gcc 2.95.2 is now the default compiler.
19991030:
/etc/radius.conf file format has changed.The format change is
as follows. Each server line in the file should now begin
with a new field containing either "auth" for RADIUS
authentication, or "acct" for RADIUS accounting. Formerly
only authentication was supported. If the first field isn't
"auth" or "acct" then the code assumes that "auth" is
intended. (That's the compatibility hack.)
19991015:
PCCARD has been updated to attach pcic to the isa bus. Therefore
you will need to modify kernel config files that have pcic/card
in them as follows:
controller pcic0 at isa?
controller pcic1 at isa?
controller card0
19990929:
The sigset_t datatype has been changed from an integral type
to a compound type and can hold 128 signals. Syscalls directly
or indirectly using the new sigset_t have been added as to
maintain compatibility with existing binaries. A new kernel must
be made and installed and booted with before a make world can
be done.
***************************************************************
RECOMPILE AND REINSTALL KERNEL BEFORE MAKEWORLD
***************************************************************
19990919:
New jail syscall format requires recompilation of jail(8) with
fresh headers installed (or a make world will do it for you).
19990914:
Matt Dillon checked in many vm related things and sent a heads up
to -current urging caution and to report vm problems to him.
As of the 19th, no killer problems have been reported, but you
have been warned.
19990908:
The new miibus has been added to the system. If you are using
the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to
add "controller miibus0" to your config file.
19990905:
/var/cron/log has been moved to /var/log/cron to get all the
log files in one place.
19990831:
tn3270 has been removed from the base system and added as a port.
19990830:
User-visible TCP timers are now expressed in units of 1ms, instead
of 500ms, so if you've customized any timer values under
``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.
19990828:
RCS Id tags changed to FreeBSD. This will cause huge cvsup
updates.
19990821:
On 28-May-1999 libreadline was upgraded from readline-2.2 to
readline-4.0. At that time the shared library major version
number was bumped from "3" to "4". It has been deemed that
the interface change between readline-2.2 and readline-4.0 was
not sufficient to warrant the version number bump.
Thus I have reverted it back to "3". You will need to perform
the below immediately before your next ``make world'':
cd /usr/lib
ls -l libreadline.so.4
(if you have /usr/lib/libreadline.so.4)
mv libreadline.so.4 libreadline.so.3
rm -f libreadline.so
ln -s libreadline.so.3 libreadline.so
19990801:
Changes to the pccardd kernel interface require that you recompile
pccardd for new kernel.
19980725:
The ipfw interface to the kernel has changed. You will need to
recompile ipfw programs for the new kernel.
19990715:
The bpfilter device has been renamed to bpf. You will need to
change your config files in order to enable this in newer kernels.
19990704:
src/contrib/sys/softupdates is moving to
src/sys/contrib/softupdates. Update your symbolic links/etc.
19990702:
Major changes have been made to vinum and its interface. See
the man page (vinum(8)) for details. Look at the concat,
mirror and stripe commands, as well as the SIMPLIFIED
CONFIGURATION section.
19990628:
Newsyslog.conf has had a minor, but potentially dangerous,
change to its username/group syntax. The old syntax was
user.group, while the new syntax is user:group.
19990627:
Inetd wrapping default has changed. Please see the updated
man page for details.
19990623:
Compaq Smart Raid driver committed as ida.
19990622:
The second phase of syscons cleanup has happened. Some
functionality has been made optional. For details, see
http://www.freebsd.org/~yokota/sc_update-June.txt
Everyone will need to re-config(8) their kernels, but old
binaries will work with the new kernel.
19990620:
IPFW uid/gid-based filtering support has been committed. This
breaks binary compatibility with previous copies of
ipfw(8). Any utilities using the ioctl()s of ipfw (especially
ipfw(8)) need to be recompiled with the newest headers
installed.
19990618:
Inetd now wraps all stream-based services, including internals.
Syslog "severity" options are honoured. Installed syslog.conf
and hosts.allow should be checked.
19990509:
Most of the problems with newbus have been corrected, but
it is still current and evolving.
libcam's ABI has changed. You must recompile the world and
any ports that use it.
19990427:
Massive changes to SMP went into the tree that should speed
things up. However, if you experience problems with SMP
machines, you can back off to the PRE_SMP_VMSHARE tag in the
CVS repository (or run an MP kernel).
19990420:
Pccardd and the pccard bus in general seem to be broken or
most people. Soren has patches to make it better for some,
but not all people. Work is underway to make it better for
all people.
19990416:
new bus changes integrated into -current. Many problems were
initially reported, but most have been fixed. You'll need a
new config and to tweak your kernel config file the way that
GENERIC was tweaked. Keep a copy of your old kernel when
upgrading in case your new kernel doesn't work (and report the
breakage to current@freebsd.org).
As of 19990421 the remaining problems/quirks are
o sio no longer supports pnp nor pccard. This will be corrected,
but the new pccard code needs to be completed.
o Some of the sound drivers broke for some people. It seems
inconsistant as to who/what/when/where things broke.
o Duplicate device entries in your config do not work. Previously
they were silently ignored. psm0 seems to be the most common
duplicate choice, although some reports have come in from people
that wired their scsi disk entries.
o You must move the keyboard and mouse attachments from the
isa bus to the atkbdc bus. See GENERIC for details.
o Machines with multiple host-pci bridges (Intel 450NX) will not
probe the second pci bus.
o Some probe ordering may have changed, so device naming may change
with the new kernel. If you have multiple devices, please double
check to make sure they didn't move. This is especially true
for cards on different buses.
o The bus attachment for vga0 is always isa0 and never pci0 when
it is in fact a pci card. It is safe to ignore this.
o The format of the boot messages has changed (and is not
guaranteed to be constant for a while) so you may see this
in some shell scripts that diff dmesg from day to day as well
as scripts that parse dmesg output.
19990414:
cc -aout sometimes has problems compiling with -g, remove -g
from those compilation units affected until this is corrected.
cc -aout has problems with producing some threaded libraries,
so make world -DWANT_AOUT is not functional at this time.
Since make world for a.out isn't functional, you cannot do
make aout-to-elf from a pre-egcs a.out system. To work around
this problem, make aout-to-elf using 3.1-stable first (or a
pre egcs -current) and then a simple make world will take you
the rest of the way with a -current source base.
19990413:
Make -j works again for make world. As always, use it with
care, and be sure to try a make world w/o -j before reporting
problems (that is, know if the problem exists w/o -j before
reporting the problem with -j).
19990413:
Note cc -aout, which had been broken since the conversion to
egcs, now supposedly works. If you have rebuilt things like
XFree86 a.out libraries, you should rebuild them again or
progams that use them, including netscape, will fail to work.
19990409:
NOTE: New c++ compiler cannot be used with c++ binaries from
the old compiler and vice versa.
19990408:
In recent days egcs has been imported into the tree. A number
of problems have been discussed in -current. Here is a highlight
of a few of the more common ones. With the exception of make
-j n, they have been claimed to have been fixed.
c++ is broken after make world: This is correct. Because we
changed compilers two make worlds are necessary to get C++
working again. The code generated by the old compiler and new
compiler are not compatible, so things wind up being
undefined.
cpp is broken in make world: There was a window where cpp
would be built incorrectly. The fix for this is
cd src/gnu/usr.bin/cc
make clean
make all
make install
and this should correct your problems. See the -current
archives for a version of this that does moer cleaning.
Make -j n doesn't work. Work contiunes to make this work,
I've seen no reports of success as of April 7th.
19990329:
Previously, one would define "NOAOUT" to keep from building
the legacy a.out bits. Now one would define "WANT_AOUT" to
build them.
19990316:
The name of the old wd.c and atapi.c based CDROM driver has
been changed back to wcd. So update your config file to use
"device wcd" instead of "device acd".
19990314:
For those of you using the VN device as a loadable module,
please be aware that the new VN device has been committed to
-4.x and cannot yet be used as a loadable module. This will
be fixed in the future.
19990309:
New loader.rc mechanism. Please see src/sys/boot/README for
details.
19990225:
struct proc size changed. Recompile kernel and the
usual suspects. Make world if in doubt.
19990214:
The nlpt driver has changed names back to be the lpt driver.
See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
for proper configuration details.
19990210:
The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
driver and 'ppbus' controller combination.
19990209:
New devstat API requires recompilation of libdevstat, systat,
iostat, vmstat and rpc.rstatd. A new kernel is also required.
make world + building a kernel should do all of this. Any
ports that use devstat need to be recompiled as well.
19990125:
Linux threads options has gone away (they are now standard in
the FreeBSD kernel). A recompile of all libkvm using programs
is in order (or better yet a make world).
19990122:
On or about this date there was a small window when the boot
blocks had some minor problems which seemed to force one to
edit /etc/fstab. This has been corrected, if you are seeing this
problem, please rebuild and reinstall your boot blocks.
19990121:
Vinum has changed. The "vinum read" command has changed. For
updates, please see
http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
for details.
Matt Dillon committed a boatload of VM changes, for
information please see
http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
or
http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
for details. These changes will likely not impact anybody,
but large chagnes to the VM need at least a heads up.
19990120:
Stable branch created. You might want to consider using this
branch. It is tagged with RELENG_3.
19990119:
More work on the syscons driver has been committed. Since
files moved around, you will need to reconfigure your kernel,
and make clean; make depend before rebuilding the kernel. No
config file changes are needed.
19990111:
New keyboard and video card drivers are introduced as the first
stage of console driver reorganization. You are required to
update the kernel configuration file and rebuild the kernel.
kbdcontrol, vidcontrol, and screen savers also need recompilation.
The instruction can be found in
http://www.freebsd.org/~yokota/sc_update.txt
It has notes on splash screen too.
19990106:
Robert Nordier was kind enough to make this page to enable people to
install the new bootblocks:
http://www.freebsd.org/~rnordier/boot.txt
When updating to ELF, make sure that you have updated your
/etc/rc files which have different ldconfig invocations for
elf and aout. Otherwise things like X will stop working with
messages about being unable to find library files. The
mergemaster utility in ports/sysutils/mergemaster helps to
keep critical files like this in sync, and its use is
recommended.
19990104:
Information about ELF day (see 19981230) can be found in

about the upcoming change, its motivations and instructions
for doing the upgrade.
19981230:
You should install new bootblocks now. The ELF kernel will
become default soon. In addition, you'll need to upgrade
your userland programs to ELF before then as well. Use
make aout-to-elf to upgrade your userland programs (old
a.out programs in, for example, /usr/local/bin will
continue to work, even after the upgrade). See src/Makefile
for more details.
19981224:
The old wcd driver has been deleted from the kernel. The
driver that replaces it is named acd. You'll need to change
this in your configuration files.
Failure to do this will result in "ATAPI CD-ROMs not
configured" at boot time.
The floppy tape driver (ft) has been removed from the kernel,
with no replacement driver.
19981202:
New groups from 19981201 commented out of mtree, so they
aren't strictly needed, but still a good idea to have.
19981201:
New user/group added: bind. From src/etc/master.passwd and
src/etc/group:
% grep <newstuff> /usr/src/etc/group
bind:*:53:
% grep <newstuff> /usr/src/etc/master.passwd
tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
19981118:
PAM integrated into the tree. Requires new /etc/pam.conf file
to silence warnings from authentication programs (login, etc).
See src/etc/pam.conf for a sample.
FORMAT:
This file contains a list, in reverse chronologocal order, of major
breakages in tracking -current. Not all things will be listed here,
and it only starts on November 18, 1998. If you have an earlier
version of FreeBSD, you are on your own to get to November 18, 1998.
Please filter your entries through Warner Losh (imp@village.org) so
that the style, formatting, etc of this file can be maintained.
