|
|
NOTE TO PEOPLE WHO THINK THAT 5.0-CURRENT IS SLOW:
|
|
FreeBSD 5.0-CURRENT has many debugging features turned on, in
|
|
both the kernel and userland. These features attempt to detect
|
|
incorrect use of system primitives, and encourage loud failure
|
|
through extra sanity checking and fail stop semantics. They
|
|
also substantially impact system performance. If you want to
|
|
do performance measurement, benchmarking, and optimization,
|
|
you'll want to turn them off. This includes various WITNESS-
|
|
related kernel options, INVARIANTS, malloc debugging flags
|
|
in userland, and various verbose features in the kernel. Many
|
|
developers choose to disable these features on build machines
|
|
to maximize performance.
|
|
|
|
20030125:
|
|
The scheduler framework has grown a second scheduler and consequently
|
|
you must specify one and only one scheduler in your kernel config.
|
|
The in cvs config files have been updated to use the old scheduler
|
|
which may be selected via 'options SCHED_4BSD'. If you would like
|
|
to try the new, much more experimental, scheduler please try
|
|
'options SCHED_ULE' and contribute to the arch@ discussion.
|
|
|
|
20030115:
|
|
A new version of the wi driver has been imported into the tree.
|
|
One now must have device wlan in the config file for it to operate
|
|
properly.
|
|
|
|
In addition, there have been some changes to how wi devices are
|
|
configured for point to point links to bring it more in line
|
|
with the former way of doing things, as well as compatibility
|
|
with NetBSD.
|
|
|
|
20021222:
|
|
For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC
|
|
used an incompatible form of ABI for returning structures and unions
|
|
which FreeBSD's GCC maintainers were not aware of relative to previous
|
|
versions of FreeBSD. We have gone back to the ABI for now, and any
|
|
code compiled which is required to interoperate with other code (not
|
|
built at the same time) returning structs or unions should be
|
|
rebuilt.
|
|
|
|
20021216:
|
|
A name change in /etc/netconfig has been reverted to stay
|
|
compatible with with suns TIRPC and also with NetBSD. You need
|
|
to run mergemaster after make world. A new libc does still work
|
|
with an outdated /etc/netconfig for some time, but you'll get
|
|
a warning. This warning will be removed in 20030301.
|
|
|
|
20021202:
|
|
The recent binutils upgrade marks a kernel flag day on
|
|
sparc64: modules built with the old binutils will not work
|
|
with new kernels and vice versa. Mismatches will result in
|
|
panics. Make sure your kernel and modules are in sync.
|
|
|
|
20021029:
|
|
The value of IPPROTO_DIVERT has changed. Make sure to keep
|
|
your kernel, netstat, natd and any third-party DIVERT
|
|
consumers in sync.
|
|
|
|
20021024:
|
|
Old, compatibility slices have been removed in GEOM kernels. This
|
|
means that you will have to update your /etc/fstab to not use
|
|
disk devices of the form /dev/ad0a. Instead, you now must
|
|
specify /dev/ad0s1a, or whatever slice your FreeBSD partition
|
|
really is on. The old device names have gone away, so if you
|
|
use them anywhere else, you must also adjust those uses.
|
|
|
|
20021023:
|
|
Alphas with kernels from between 20020830 and 20021023 and/or
|
|
rtld (ld-elf.so.1) older than 20021023 may experience problems
|
|
with groff while doing a buildworld (kernel: "out of memory",
|
|
fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD
|
|
segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c).
|
|
|
|
So, to successfully upgrade your Alpha, you must either
|
|
upgrade your kernel and rtld first (which might be a bit
|
|
tricky), or avoid running the bootstrapped groff during the
|
|
"transitional" buildworld. To avoid running groff during the
|
|
transitional upgrade run make buildworld with -DNOMAN,
|
|
-DNO_SHAREDOCS, and -DNO_LPR.
|
|
|
|
20020831:
|
|
gcc has been upgraded to 3.2. It is not all binary compatible
|
|
with earlier versions of gcc for c++ programs. All c++
|
|
programs and libraries need to be recompiled.
|
|
|
|
Also, if you encounter g++ issues, rm /usr/include/g++/* before
|
|
doing an installworld to make sure that stale files are removed.
|
|
|
|
20020827:
|
|
Our /etc/termcap now has all the entries from the XFree86 xterm
|
|
almost unchanged. This means xterm now supports color by default.
|
|
If you used TERM=xterm-color in the past you now should use
|
|
TERM=xterm. (xterm-color will lead to benign warnings).
|
|
|
|
20020815:
|
|
A "bug" in gcc(1) that was hiding warning in system headers was
|
|
fixed. It's probably time to add -DNO_WERROR to your make line
|
|
again.
|
|
|
|
20020729:
|
|
COPY is being deprecated. The 20010530 change was reverted, as
|
|
it causes far more pain than was expected, and to always compare
|
|
before installing, please use INSTALL="install -C" again. The
|
|
-C option is now silently ignored when used with the -d option.
|
|
|
|
20020702:
|
|
Problems with libc_r clients like KDE and GNOME have been resolved.
|
|
There are still some minor problems with some signals but the
|
|
system is stable enough for general use again. SMP is less so than UP
|
|
but each can successfully complete multiple buildworlds.
|
|
Libkvm needs to be recompiled due to KSE.
|
|
|
|
20020701:
|
|
Now would be a bad time to upgrade. Something in or near the
|
|
KSE commit totally broke programs using libc_r like KDE and
|
|
GNOME.
|
|
|
|
20020511:
|
|
The k5su utility installed as part of Kerberos 5 is no longer
|
|
installed with the set-user-ID bit set by default. Add
|
|
ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed
|
|
with the set-user-ID bit set.
|
|
|
|
20020510:
|
|
Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2.
|
|
Unfortunately our native GDB (at version 4.18) does not understand
|
|
the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to
|
|
generated debugging information for our native GDB.
|
|
|
|
20020510:
|
|
Due to the way CVS works, it may not properly update src/contrib/gcc
|
|
to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc
|
|
and then do a cvs update.
|
|
|
|
20020421:
|
|
When exec'ing set[ug]id executables, the kernel now ensures that the
|
|
stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio.
|
|
|
|
20020404:
|
|
New sendmail startup scripts have been installed to make it
|
|
easier to use alternative MTAs with FreeBSD. Setting the rc.conf
|
|
variable sendmail_enable to "NO" no longer prevents any sendmail
|
|
daemons from starting. Instead, either set sendmail_enable to
|
|
"NONE" or change mta_start_script to a script for starting
|
|
an alternative MTA. Setting mta_start_script to "" will
|
|
also prevent any MTA from being started at boot.
|
|
|
|
20020403:
|
|
UCONSOLE is no longer a valid kernel option.
|
|
|
|
20020315:
|
|
FreeBSD 5.0 DP-1 was basically branched today.
|
|
|
|
20020225:
|
|
Warnings are now errors in the kernel. Unless you are a developer,
|
|
you should add -DNO_WERROR to your make line.
|
|
|
|
20020217:
|
|
sendmail 8.12.2 has been imported. The sendmail binary is no
|
|
longer a set-user-ID root binary and the infrastructure to support
|
|
command line mail submission has changed. Be sure to run
|
|
mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
|
|
and /etc/mail) and read /etc/mail/README for more details.
|
|
|
|
Due to the import of sendmail 8.12.2, a new user and group are
|
|
required in order for sendmail to run as a set-group-ID
|
|
binary. A 'make installworld' will use the new user and group
|
|
to set the owner and group of /var/spool/clientmqueue and will
|
|
fail if the new user and group do not exist. The 'smmsp' user
|
|
and group must be merged from src/etc/group and
|
|
src/etc/master.passwd before using 'make installworld'.
|
|
'mergemaster -p' will do this. You may need to install
|
|
mergemaster before this will work if you are updating from a
|
|
very old version of current. The updating recipe has changed
|
|
as of this date.
|
|
|
|
20020112:
|
|
The preferred configuration method for PAM is now /etc/pam.d/
|
|
rather than /etc/pam.conf. If you have an unmodified
|
|
pam.conf, just delete it after your next mergemaster run. If
|
|
you have local modifications, you can use
|
|
/usr/src/etc/pam.d/convert.pl to incorporate them into your
|
|
/etc/pam.d.
|
|
|
|
Please see the following url for more details:

|
|
20011229:
|
|
If anyone here is already using the new rc.conf(5) variable
|
|
networkfs_types, please note that it has changed
|
|
http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za>
|
|
|
|
20011220:
|
|
sys/i4b/driver/i4b_ispppsubr.c has been retired. This file
|
|
started out its life in the ISDN4BSD project as an offspring
|
|
from sys/net/if_spppsubr.c, which eventually got a life of its
|
|
own. All the accumulated features and bugfixes of the i4b
|
|
version have now been merged back into the base system's
|
|
version now. The only user-visible change resulting from this
|
|
is that i4b's sppp(4) interfaces are to be managed with
|
|
spppcontrol(8) again, since ispppcontrol(8) has been retired
|
|
as well. (There has never been rc file support for
|
|
ispppcontrol in -current, but only in -stable. That will be
|
|
reverted by the time the changes are MFCed.)
|
|
|
|
20011215:
|
|
The fdc(4) driver has been updated and now automatically
|
|
recognizes media in `standard' formats (like 1440 KB and
|
|
720 KB for a 3.5" high-density drive) when accessing the
|
|
default device node (e. g. /dev/fd0). The old variety of
|
|
floppy device nodes /dev/fd*.* is no longer present by
|
|
default, devices can be created (in DEVFS) on demand. They
|
|
will need to be customized then for `odd' densities using
|
|
fdcontrol(8).
|
|
|
|
20011209:
|
|
The bugs in procfs' debugging support code have been fixed,
|
|
and truss(1) now works again.
|
|
|
|
20011207:
|
|
Daily security checks have been split out to use the periodic(8)
|
|
scripts. Some change in configuration may be necessary. Please
|
|
see
|
|
http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org>
|
|
for details.
|
|
|
|
20011204:
|
|
sos added VCD/SVCD support to ata driver and that needs the
|
|
kernel and burncd to be in sync.
|
|
|
|
20011203:
|
|
The procfs pseudo-filesystem has now been converted to use the
|
|
pseudofs framework. If you have 'options PROCFS' in your
|
|
kernel config, you'll need to add 'options PSEUDOFS' if it's
|
|
not there already.
|
|
|
|
This change temporarily breaks truss(1); use ktrace(1) instead
|
|
until the issue has been resolved.
|
|
|
|
20011202:
|
|
A security hole in OpenSSH involving `UseLogin yes' has been
|
|
patched.
|
|
|
|
20011126:
|
|
You need to remove /usr/obj/.../usr.bin/tip before rebuilding
|
|
after this date. You need to do this only once.
|
|
|
|
20011103:
|
|
Most of the awk issues have been resolved. Some rough
|
|
edges may be left, but for the most part things should be
|
|
back to "normal." For CURRENT's usual definition of "normal."
|
|
|
|
20011030:
|
|
Awk has been upgraded to the one true awk from bell labs. Expect
|
|
choppy waves in the upgrade process.
|
|
|
|
20011030:
|
|
The asr driver problem has been resolved.
|
|
|
|
20011027:
|
|
Due to changes in other parts of the system, the asr driver
|
|
now causes the system to panic on boot. Do not use it pending
|
|
correction. Comment it out of any kernel config file that you
|
|
try to use from this date forward.
|
|
|
|
20011025:
|
|
When crossbuilding, use TARGET=xxx where you used to use
|
|
MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET,
|
|
unless you are changing both of them. To cross build pc98 on
|
|
an alpha, for example, you need to set TARGET=pc98 and
|
|
TARGET_ARCH=i386.
|
|
|
|
20011001:
|
|
The kernel interface that burncd depends on has changed.
|
|
You must recompile both the kernel and userland applications
|
|
at the same time.
|
|
|
|
20010929:
|
|
When crossbuilding, please set TARGET_ARCH rather than
|
|
MACHINE_ARCH to indicate the target. In the future, one will
|
|
set TARGET_MACHINE where you set MACHINE now. At the moment,
|
|
setting MACHINE alone for same MACHINE_ARCH machines works
|
|
(eg, you can build pc98 on an i386 machine and vice versa).
|
|
|
|
20010927:
|
|
Some weird problems result from using ACPI on some machines.
|
|
To disable ACPI you can add
|
|
hint.acpi.0.disable="1"
|
|
to /boot/loader.conf (or by putting set X=Y at the boot
|
|
loader "ok" prompt).
|
|
|
|
Alternatively, you can remove it from /boot/kernel/acpi.ko
|
|
or use the MODULES_OVERRIDE function in your kernel config
|
|
file and not list acpi in that list.
|
|
|
|
20010924:
|
|
The buildworld has been fixed. You may need to install
|
|
the 4.x compatibility libraries for some old binaries
|
|
to work. Add COMPAT4X=true to your /etc/make.conf to
|
|
get them installed on every installworld, or execute the
|
|
following to get them installed only once:
|
|
cd src/lib/compat/compat4x.<arch>
|
|
make all install
|
|
You will see ``__stdoutp undefined'' until you do this.
|
|
|
|
20010919:
|
|
There's a bug in the world build process. The cross-tools
|
|
are build with the NEW headers, but the OLD libc.a. This
|
|
leads to all kinds of problems with the new libc. A temporary
|
|
workaround is to add
|
|
CFLAGS="-O -pipe -D_OLD_STDIO"
|
|
before building world when upgrading from 4.x to current. This
|
|
can be removed afterwards.
|
|
|
|
A proper fix to the buildworld target is needed.
|
|
|
|
20010918:
|
|
Peter has committed his new kthread nfs client/server code.
|
|
NFS may be unstable after this date.
|
|
|
|
20010912:
|
|
KSE has hit the tree. Lots of things are now different in
|
|
the kernel. While a few problems were introduced in the
|
|
initial commit, most of the major ones have been found and
|
|
corrected.
|
|
|
|
20010901:
|
|
In OLDCARD, CardBus bridges appear to be stable. The work
|
|
arounds described in the 20010604 entry are now no longer
|
|
necessary and will be ignored. Most insert/remove problems
|
|
have been rectified around this date.
|
|
|
|
20010823:
|
|
named now runs as user bind and group bind rather than as
|
|
root. If named_enable is set to YES in /etc/rc.conf, ensure
|
|
that user bind is available in /etc/passwd (using vipw(8))
|
|
and that group bind is available in /etc/group. Also make
|
|
sure that user or group bind has read (and not write)
|
|
permission for your name server configuration and that it
|
|
has read and write permission for your slave zone files and
|
|
directory.
|
|
|
|
If you wish to continue to run named as root (a less secure
|
|
alternative), add a line to /etc/rc.conf saying
|
|
|
|
named_flags=
|
|
|
|
20010709:
|
|
The PAM libraries have had an API upgrade that is beyond
|
|
the ability of the shared library major number to handle.
|
|
It is manifested by PAM-using ports dumping core. The
|
|
solution is to rebuild those ports.
|
|
|
|
20010628:
|
|
The kernel compile module has moved from src/sys/compile/FOO
|
|
to src/sys/${MACHINE}/compile/FOO.
|
|
|
|
20010625:
|
|
The pccard modem issue from 20010613 has been corrected.
|
|
OLDCARD support is still a little weak in -current. slot 1 is
|
|
known not to work on some TI based cardbus bridges. Some
|
|
cardbus bridges do not properly detect insert/removal events.
|
|
IRQ configuration needs more safety belts.
|
|
|
|
20010617:
|
|
Softupdates problems have been corrected.
|
|
|
|
20010614:
|
|
Peter ripped out the linkerset support. You must, as always,
|
|
rerun config after you cvsup if you are using the traditional
|
|
kernel building methods.
|
|
|
|
20010613:
|
|
pccard modems may not work with current after 20010604 date. Some
|
|
do, others result in panics. *MAKE*SURE* that you update your
|
|
config and /etc/rc.conf ala the 20010604 entry, or you will have
|
|
problems (this issue will be fixed, it just hasn't been yet).
|
|
|
|
20010613:
|
|
SOFTUPDATES seem to be broken since the middle of May or so. Do not
|
|
use them in current. You can disable softupdates on all mounted
|
|
partitions, or remove SOFTUPDATES the kernel config file.
|
|
|
|
20010612:
|
|
After Peter's commits to the hints code, people have been noticing
|
|
that certain devices are attached (or try to) twice. This is due
|
|
to having both static hints as well as a /boot/device.hints. To
|
|
work around this issue, please use only one or the other mechanism
|
|
until this bug is fixed.
|
|
|
|
Please note that a feature of config is that if you have config
|
|
file FOO and FOO.hints, it automatically adds FOO.hints to the
|
|
hints.c file, wheather you want it to or not.
|
|
|
|
20010610:
|
|
Locale names have changed to match other systems better.
|
|
|
|
20010604:
|
|
pccard support for pci cards has been committed. You must change
|
|
your /etc/pccard.conf irq lines. It must match the irq used by
|
|
pcic device. Interrupt storms may result if you fail to do this.
|
|
Interrupt storms look a lot like a hang.
|
|
|
|
You must also install a new pccardd, otherwise you will get an
|
|
interrupt storm at card reset time (just after it tells you what
|
|
it is).
|
|
|
|
pccardd_flags="-I" is necessary for the time being. It tells pccardd
|
|
not to ask the kernel if the interrupt is really free or not before
|
|
using it. You can either change the /etc/pccard.conf irq lines to
|
|
match pcic, or add "-i X" to the pccardd_flags.
|
|
|
|
20010530:
|
|
INSTALL=install -C is being deprecated. If you want to do this,
|
|
use COPY=-C instead. The former method will be supported for only
|
|
a limited time. If you see
|
|
|
|
install: warning: the -d and -C options may not be specified together
|
|
|
|
in your makeworld, then you need to migrate towards using
|
|
COPY=-C.
|
|
|
|
20010525:
|
|
It appears that vm is now stable enough to use again. However,
|
|
there may be other problems, so caution is still urged. alpha
|
|
definitely is in bad shape.
|
|
|
|
20010521:
|
|
Minor repo damange has happened. This may cause problems
|
|
with cvsup of ports. If you get errors, please see
|
|
http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495
|
|
at the bottom for details on a workaround. The error message
|
|
is
|
|
Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty
|
|
|
|
20010520:
|
|
Vm and/or swapping are busted on -current. Please be patient.
|

pccard has had much reorganizational work done to it over
|
|
the past few days. Everything should still work, but if
|
|
not, please contact imp@freebsd.org.
|
|
|
|
20010517:
|
|
ata ioctl changed. Make sure to recompile both kernel and
|
|
userland at the same time.
|
|
|
|
20010517:
|
|
New ncurses imported.
|
|
|
|
20010512:
|
|
DEVFS is now opt out, not opt in. Barring major problems, this
|
|
will be the only way to go starting July 1.
|
|
|
|
20010504:
|
|
OpenSSH has been updated to 2.9. Some defaults are different,
|
|
including RhostsRSAAuthentication, which changes from yes to no.
|
|
|
|
20010502:
|
|
Perl breakage in 20010501 was corrected at 14:18:33 PDT.
|
|
|
|
20010501:
|
|
Building perl was broken at 02:25:25 PDT.
|
|
|
|
20010430:
|
|
The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to
|
|
go back in the water.
|
|
|
|
20010429:
|
|
A bad bug was committed at 04:48:42 PDT. Don't use kernels after
|
|
this date, but before the correction date.
|
|
|
|
20010423:
|
|
old fsck and new kernel interactions appear to have been fixed.
|
|
|
|
20010411:
|
|
fsck and the kernel were changed to handle some optimizations
|
|
to directory layout. This breaks backward compatibility.
|
|
Update only if you understand that you must not use the old
|
|
fsck with the new kernel ever.
|
|
|
|
20010330:
|
|
fsck has changed the meaning of the pass column in /etc/fstab.
|
|
Please see the cvs commit to fsck.8 or the fsck.8 man page for
|
|
details. It is unclear if changes to /etc/fstab are necessary.
|
|
|
|
20010319:
|
|
portmap had changed name to rpcbind for maximum POLA in your
|
|
current world. /etc/hosts.{allow,deny} needs changes. nfs and
|
|
other rpc based programs that rely on portmapper will not work
|
|
without updates to /etc/hosts.{allow,deny} and /etc/netconfig.
|
|
|
|
20010315:
|
|
ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC
|
|
and ATA_ENABEL_TAGS are no longer kernel options. They have
|
|
been replaced by tunables. See ata.4 for details.
|
|
|
|
20010312:
|
|
The fxp driver was converted to use miibus. If you compile
|
|
fxp into your kernel statically, you will need to add miibus.
|
|
|
|
20010312:
|
|
The wi device now defaults to BSS (infrastructure) mode
|
|
instead of ad-hoc.
|
|
|
|
20010310:
|
|
/dev/urandom should be a symbolic link to /dev/random now.
|
|
Users of current not using DEVFS need to run MAKEDEV std.
|
|
ssh might not work if you don't.
|
|
|
|
20010303:
|
|
The ed driver has been updated. It now allows mii attachments,
|
|
which means that you must include the miibus in your kernel if
|
|
you use the ed driver.
|
|
|
|
20010220:
|
|
The problems with libc have been corrected. It is now mostly
|
|
safe to go back into the water.
|
|
|
|
20010211:
|
|
The size of FILE was changed. This breaks upgrading. If
|
|
you must upgrade, be prepared for pain. It also breaks almost
|
|
all binaries that you've compiled on -current. You are warned
|
|
that before upgrading would be a good time to do a level 0
|
|
dump of your system. No, really, I mean it this time.
|
|
|
|
To get to the new system, you'll need to use the following
|
|
workaround. Hopefully this can be sorted out so that we
|
|
don't have to move this to the updating section.
|
|
|
|
To get around the installworld problem, do:
|
|
# cd /usr/src/usr.bin/sed
|
|
# make install
|
|
# cd /usr/src
|
|
# make installworld
|
|
If that doesn't work, then try:
|
|
# make -k installworld
|
|
# make installworld
|
|
|
|
20010207:
|
|
DEVFS is now the default. If you use vinum, make sure that you
|
|
do not include devfs in your kernel as problems result.
|
|
|
|
20010205:
|
|
FFS_ROOT and CD9660_ROOT have been removed or deprecated.
|
|
Remove them from your config.
|
|
|
|
20010122:
|
|
****************************** WARNING ******************************
|
|
buildkernel has been changed slightly
|
|
****************************** WARNING ******************************
|
|
KERNCONF replaces the variable KERNEL for buildkernel. You
|
|
should update your scripts and make.conf accordingly.
|
|
|
|
20010119:
|
|
config has changed to allow DEV_FOO as a replacement for NFOO.
|
|
This requires a new config to build correctly.
|
|
|
|
20010116:
|
|
The kerrnel option I386_CPU is now mutually exclusive with the
|
|
other cpu types. If you have an i386 system, be sure that it
|
|
only had this line. Remove it for all other configurations.
|
|
|
|
20010110:
|
|
Changes to the kernel require it and burncd be in sync.
|
|
|
|
20010102:
|
|
Everyone who has hw.sndunit set to something in
|
|
/etc/sysctl.conf, it is now hw.snd.unit.
|
|
|
|
20010101:
|
|
ex and vi were broken by some changes to sys/queue.h. If you
|
|
have a bad vi, you will see make buildworld fail with a core
|
|
dump while building termcap. You can work around this problem
|
|
by adding -k to your make buildworld. This will cause the
|
|
build to complete and install a new vi. Once that's done, you
|
|
can rebuild again without the -k to pick up anything that
|
|
might have been ignored by the -k option.
|
|
|
|
Others have suggested that you can just rebuild libc if your
|
|
vi/ex is dynamically linked, but I've not received any reports
|
|
of this working.
|
|
|
|
20001228:
|
|
There have been some changes to libcrypt in -current. The
|
|
libscrypt/libdescrypt symlink sillyness is gone and the installed
|
|
libcrypt is fully functional. Be aware of this.
|
|
|
|
20001218:
|
|
Linksys Fast Ethernet PCCARD cards supported by the ed driver
|
|
now require the addition of flag 0x80000 to their config line
|
|
in pccard.conf(5). This flag is not optional. These Linksys
|
|
cards will not be recognized without it.
|
|
|
|
20001205:
|
|
Important new FreeBSD-version stuff: PAM support has been worked
|
|
in, partially from the "Unix" OpenSSH version. This requires
|
|
adding the following in pam.conf:
|
|
|
|
sshd auth sufficient pam_skey.so
|
|
sshd auth required pam_unix.so try_first_pass
|
|
sshd session required pam_permit.so
|
|
|
|
20001031:
|
|
cvs updated to 1.11.
|
|
|
|
20001020:
|
|
The random device needs more entropy, so you need to make sure
|
|
that you've run mergemaster to get a /etc/rc which will seed
|
|
/dev/random. If you don't and the system hangs after ldconfig,
|
|
then banging on the keyboard randomly until it unhangs is one
|
|
workaround.
|
|
|
|
20001010:
|
|
****************************** WARNING ******************************

|
20001009:
|
|
The ports tree's new layout is in place. Be sure to update
|
|
your entire ports tree, or you will have problems.
|
|
|
|
20001006:
|
|
The perl build procedure no longer installs miniperl, nor uses
|
|
the installed miniperl. It is recommended that you delete
|
|
/usr/bin/miniperl.
|
|
|
|
20001005:
|
|
This weekend the ports tree will be updated to a new layout.
|
|
It will be in an inconsistent state until noted in the UPDATING
|
|
file, or with asami-san's message to the relevant mailing
|
|
lists. With this new layout, you'll need to update the whole
|
|
tree for anything to work.
|
|
|
|
20000928:
|
|
There was a change in the passwd format. Need more information.
|
|
|
|
20000916:
|
|
/boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken
|
|
place. Please update boot loader (not the boot blocks) at the
|
|
same time as your kernel.
|
|
|
|
20000914:
|
|
The new pmtimer device is necessary for laptops. Failure to
|
|
include the device will cause suspended laptops losing time
|
|
when they resume. Include
|
|
device pmtimer
|
|
in your config file and
|
|
hint.pmtimer.0.at="isa"
|
|
to your /boot/device.hints file.
|
|
|
|
20000911:
|
|
The random device has been turned into a (pseudo-)device,
|
|
rather than an option. The supplied kernel config files have
|
|
been updated. You will need to do something similar in your
|
|
own kernel config file.
|
|
Remove:
|
|
options RANDOMDEV
|
|
Add:
|
|
device random
|
|
If you prefer to load the loadable module, you need to do
|
|
nothing.
|
|
|
|
20000909:
|
|
The random device module has been renamed from randomdev.ko to
|
|
random.ko. You will need to edit your /boot/loader.conf to
|
|
reflect this if you load this module at boot time.
|
|
The line should read:
|
|
random_load="YES"
|
|
|
|
20000907:
|
|
The SMPNG commit has happened. It should work, but if it
|
|
doesn't, fallback to the PRE_SMPNG CVS tag. There are likely
|
|
to be a variety of minor issues. Please see 20000905 to make
|
|
sure you don't have model loading problems which might at
|
|
first blush appear related to SMP.
|
|
|
|
20000906:
|
|
nsswitch has been imported from NetBSD. Among other things,
|
|
this means that /etc/host.conf is no longer used. See
|
|
nsswitch.conf(5) instead. Note that at boot time rc.network
|
|
will attempt to produce a new nsswitch.conf file for you if you
|
|
don't have one, and you have host.conf.
|
|
|
|
20000905:
|
|
The ucred structure changed size. This breaks the interface
|
|
that mountd uses. Trying to use an older mountd with a newer
|
|
kernel guarantees a panic. This means that you need to use
|
|
kernels newer than today only with matching mountd, but you
|
|
needed to do that anyway with the boot loader changes.
|
|
|
|
20000905:
|
|
The boot loader has been updated. The new default kernel is
|
|
now /boot/kernel/kernel.ko. The new default module location
|
|
is /boot/kernel.
|
|
|
|
You *MUST* upgrade your boot loader and kernel at the same time.
|
|
The easiest way to do this is to do the buildworld/buildkernel/
|
|
installkernel/installworld dance.
|
|
|
|
Furthermore, you are urged to delete your old /modules directory
|
|
before booting the new kernel, since kldload will find stale
|
|
modules in that directory instead of finding them in the correct
|
|
path, /boot/kernel. The most common complaint that this cures
|
|
is that the linux module crashes your machine after the update.
|
|
|
|
if [ ! -d /boot/kernel.old ]; then
|
|
mv /modules.old /boot/kernel.old
|
|
chflags noschg /kernel.old
|
|
mv /kernel.old /boot/kernel.old/kernel.ko
|
|
chflags schg /boot/kernel.old/kernel.ko
|
|
fi
|
|
|
|
20000904:
|
|
A new issue with the sendmail upgrade has come to light.
|
|
/etc/aliases has moved to /etc/mail/aliases. Mergemaster will
|
|
incorrectly install the default aliases in /etc/mail rather than
|
|
move the old one from /etc. So you'll need to manually move the
|
|
file, create a symbolic link, remove the old /etc/aliases.db and
|
|
run newaliases. For safety sake, you should stop sendmail
|
|
while doing this and run the upgrade when locally sourced email
|
|
is not likely to be generated.
|
|
|
|
20000825:
|
|
/boot/device.hints is now required for installkernel to
|
|
succeed. You should copy GENERIC.hints for your architecture
|
|
into /boot/device.hints. If and only if you compile hints
|
|
into your kernel, then this file may be empty. Please note,
|
|
if you have an empty or missing /boot/device.hints file and
|
|
you neglected to compile hints into your kernel, no boot
|
|
messages will appear after the boot loader tries to start the
|
|
kernel.
|
|
|
|
20000821:
|
|
If you do NOT have ``options RANDOMDEV'' in your kernel and
|
|
you DO want the random device then add randomdev_load="YES" to
|
|
/boot/loader.conf.
|
|
|
|
20000812:
|
|
suidperl is now always built and installed on the system, but
|
|
with permissions of 511. If you have applications that use
|
|
this program, you are now required to add ENABLE_SUIDPERL=true
|
|
to /etc/make.conf. If you forget to do this,
|
|
chmod 4511 /usr/bin/suidperl
|
|
will fix this until the next build.
|
|
|
|
20000812:
|
|
sendmail has been updated from 8.9.3 to 8.11.0. Some of the more
|
|
visible changes that may immediately affect your configuration
|
|
include:
|
|
- New default file locations from src/contrib/sendmail/cf/README
|
|
- newaliases limited to root and trusted users
|
|
- MSA port (587) turned on by default
|
|
- New queue file naming system so can't go from 8.11 -> 8.9
|
|
- FEATURE(`rbl') renamed to FEATURE(`dnsbl')
|
|
- FEATURE(`nullclient') is more full featured
|
|
- FEATURE(`nouucp') requires an argument: `reject' or `nospecial'
|
|
- mail.local FreeBSD-only -b option changed to -B
|
|
- See src/contrib/sendmail/RELEASE_NOTES for more info
|
|
|
|
20000810:
|
|
suidperl (aka sperl) is no longer build by default. You must
|
|
specifically define BUILD_SUIDPERL to "true" for it to be build.
|
|
Furthermore, we recommend that you remove /usr/bin/sperl* and
|
|
/usr/bin/suidperl files from your system unless you have a
|
|
specific use for it.
|
|
|
|
20000729:
|
|
Networking defaults have been tightened. Anybody upgrading
|
|
/etc/defaults/rc.conf needs to add the following lines to
|
|
/etc/rc.conf if they want to have the same setup
|
|
afterwards (unless the variables already are set, of course):
|
|
# Enable network daemons for user convenience.
|
|
inetd_enable="YES"
|
|
portmap_enable="YES"
|
|
sendmail_enable="YES"
|
|
|
|
20000728:
|
|
If you have null_load="YES" in your /boot/loader.conf, you
|
|
will need to change that to nullfs_load="YES".
|
|
|
|
20000728:
|
|
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.
|
|
|
|
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.
|
|
|
|
20000711:
|
|
/etc/security has been updated to print the inode number of
|
|
setuid programs that have changed. You will see a large spike
|
|
in the number of changed programs the first time when you run
|
|
mergemaster to get a new /etc/security.
|
|
|
|
20000710:
|
|
/dev/random now has good entropy collection (from the keyboard
|
|
and sysmouse drivers). Please ensure that either `options
|
|
RANDOMDEV' is present in your kernel config file or that
|
|
`randomdev_load="YES"' is in your /boot/loader.conf. If you do
|
|
not have the /dev/random driver, OpenSSL (and consequently
|
|
lots of crypto tools (like SSH)) will fail with strange
|
|
errors. (see below, 20000624).
|
|
|
|
FreeBSD-current is safe again to run Crypto.
|
|
|
|
20000709:
|
|
phk made the malloc default options AJ. This may slow things
|
|
down and uncover other latent bugs in the code. If you need to
|
|
run at full speed, you can disable this by doing the following:
|
|
ln -s aj /etc/malloc.conf
|
|
|
|
20000706:
|
|
libftpio's version was accidentally bumped a few days ago. This
|
|
has been corrected. You may need to remove /usr/lib/libftpio.so.6
|
|
before doing your next buildworld/installworld pair. It certainly
|
|
won't hurt to remove it before the update procedure. It will
|
|
break fetch until a new one is built, but ftp can be used in the
|
|
interim if needed.
|
|
|
|
20000705:
|
|
The crypto packages have changed for the cvsup. This has been done
|
|
in a backward compatible way, but the old packages will go away at
|
|
some point in the future. Look at /usr/share/examples/cvsup for
|
|
details.
|
|
|
|
20000704:
|
|
With the new sys/modules/sound/drivers/*, you will need to
|
|
set SYSDIR until you do an installworld after July 7th.
|
|
|
|
20000704:
|
|
rc.shutdown and rc will now call the rc.d scripts with start
|
|
or stop. This may cause some harmless warnings from older
|
|
rc.d scripts that haven't been updated.
|
|
|
|
20000630:
|
|
The libfetch based version of fetch has gone into the tree.
|
|
Minor problems may result on some of the less popular sites,
|
|
which should be reported to des@freebsd.org.
|
|
|
|
20000625:
|
|
From approximately this date forward, one must have the crypto
|
|
system installed in order to build the system and kernel.
|
|
While not technically strictly true, one should treat it as
|
|
required and grab the crypto bits. If you are grabbing CVS
|
|
trees, src-all and cvs-crypto should be treated as if they
|
|
were required. You should check with the latest collections
|
|
to make sure that these haven't changed.
|
|
|
|
20000624:
|
|
Mark Murray just committed the first parts of a cleanup of
|
|
/dev/zero, et al. This is also cleaning up /dev/random.
|
|
The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD
|
|
-CURRENT FROM THIS POINT to 2000710 for cryptographic services
|
|
until Mark can merge in the fixes to this work in progress.
|
|
openssh and openssl should not be used to generate keys from this
|
|
date to the completion of the work.
|
|
|
|
If you must operate at this reduced level of security, add '
|
|
options RANDOMDEV' to your kernel or modload the randomdev
|
|
module. You may also need to copy a new MAKEDEV to /dev and
|
|
recreate the random and urandom devices.
|
|
|
|
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.
|
|
|
|
20000621:
|
|
Scott Flatman <sf@aracnet.com> sent in a decent write-up on
|
|
the config file update procedure.
|
|
http://people.freebsd.org/~imp/config-upd.html
|
|
NOTE: LINT is gone. It has been replaced with NOTES. NOTES
|
|
isn't buildable. However, you can generate a LINT file.
|
|
|
|
20000620:
|
|
Binutils 2.10 have hit the tree, or will shortly. As soon
|
|
as they do, the problem noted in 20000522 will be resolved and
|
|
that workaround will no longer be required.
|
|
|
|
20000615:

phk removed the compatibility creation of wd devices in the
|
|
ad driver. If you haven't done so already, you must update
|
|
your fstab, etc to use the ad devices instead of the wd
|
|
devices.
|
|
|
|
In addition, you'll need to update your boot blocks to a
|
|
more modern version, if you haven't already done so. Modern
|
|
here means 4.0 release or newer (although older releases
|
|
may work).

Peter took an axe to config(8). Be sure that you read his mail
|
|
on the topic before even thinking about updating. You will
|
|
need to create a /boot/device.hints or add a hints directive
|
|
to your config file to compile them in statically. The format
|
|
of the config file has changed as well. Please see GENERIC or
|
|
NEWCARD for examples of the new format.
|
|
|
|
Indirectly, this also breaks USERCONFIG. Unless a newer entry
|
|
says that it has been fixed, assume that must use the hints mechanism
|
|
in the loader if you need to use a machine with very old ISA cards
|
|
in it.

A new set of binutils went into the tree today. Anybody
|
|
building a kernel after this point is advised that they need
|
|
to rebuild their binutils (or better yet do a
|
|
buildworld/installworld) before building a new kernel.
|
|
|
|
Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
|
|
or MALLOC_OPTIONS env var) J will cause ld to dump core. It
|
|
is recommended that you don't set this option until the problem
|
|
is resolved.
|
|
|
|
20000513:
|
|
The ethernet drivers were all updated to clean up the BPF handling.
|
|
|
|
20000510:
|
|
The problems with boot blocks on the alphas have been corrected.
|
|
This will require some care in updating alphas. A new libstand
|
|
is requires for the boot blocks to build properly.
|
|
|
|
20000503:
|
|
Recompile all kld modules. Proper version dependency info
|
|
is now available.
|
|
|
|
20000502:
|
|
Modules have been disconnected from the buildworld tree and
|
|
connected to the kernel building instead.
|
|

|
|
You may need to build gperf
|
|
cd /usr/src/gnu/usr.bin/gperf && make depend all install
|
|
when upgrading from 4.0 -> current. The build system now uses
|
|
an option only in -current.
|
|
|
|
20000417:
|
|
The method that we brand ELF binaries has changed to be more
|
|
acceptable to the binutils maintainers. You will need to
|
|
rebrand your ELF binaries that aren't native. One problem
|
|
binary is the Linux ldconfig. After your make world, but
|
|
before you reboot, you'll need to issue:
|
|
brandelf -t Linux /compat/linux/sbin/ldconfig
|
|
if you have Linux compatibility enabled on your machine.
|
|
|
|
20000320:
|
|
If you have really bad/marginal IDE drives, you may find they
|
|
don't work well. Use pio mode instead. The easiest way to
|
|
cope if you have a problem combination is to add:
|
|
/sbin/sysctl hw.ata.ata_dma=0
|
|
to the start of /etc/rc.conf.
|
|
|
|
20000319:
|
|
The ISA and PCI compatibility shims have been connected to the
|
|
options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
|
|
style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
|
|
include the appropriate option in your kernel config. Drivers
|
|
using the shims should be updated or they won't ship with
|
|
5.0-RELEASE, targeted for 2001.
|
|
|
|
20000318:
|
|
We've entered the traditional post release dumping party.
|
|
Large kernel changes are being committed and are in the
|
|
works. It is important to keep the systems' klds and kernel
|
|
in sync as kernel interfaces and structures are changing.
|
|
Before reporting kernel panics, make sure that all modules
|
|
that you are loading are up to date.
|
|
|
|
20000315:
|
|
If you are upgrading from an older version of FreeBSD, you
|
|
need to update your boot blocks as well. 'disklabel -B ad0'
|
|
will do the trick. This isn't critical until you remove your
|
|
wd device entries in /dev, at which point your system will not
|
|
boot.
|
|
|
|
20000315:
|
|
4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
|
|
to upgrade to 4.0 from 3.x.
|
|
|
|
COMMON ITEMS:
|
|
|
|
General Notes
|
|
-------------
|
|
Avoid using make -j when upgrading. From time to time in the
|
|
past there have been problems using -j with buildworld and/or
|
|
installworld. This is especially true when upgrading between
|
|
"distant" versions (eg one that cross a major release boundary
|
|
or several minor releases, or when several months have passed
|
|
on the -current branch).
|
|
|
|
Sometimes, obscure build problems are the result of environment
|
|
poisoning. This can happen because the make utility reads its
|
|
environment when searching for values for global variables.
|
|
To run your build attempts in an "environmental clean room",
|
|
prefix all make commands with 'env -i '. See the env(1) manual
|
|
page for more details.
|
|
|
|
To build a kernel
|
|
-----------------
|
|
If you are updating from a prior version of FreeBSD (even one just
|
|
a few days old), you should follow this procedure. With a
|
|
/usr/obj tree with a fresh buildworld,
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
|
|
To just build a kernel when you know that it won't mess you up
|
|
--------------------------------------------------------------
|
|
cd src/sys/{i386,alpha}/conf
|
|
config KERNEL_NAME_HERE
|
|
cd ../../compile/KERNEL_NAME_HERE
|
|
make depend
|
|
make
|
|
make install
|
|
|
|
If this fails, go to the "To build a kernel" section.
|
|
|
|
To rebuild everything and install it on the current system.
|
|
-----------------------------------------------------------
|
|
# Note: sometimes if you are running current you gotta do more than
|
|
# is listed here if you are upgrading from a really old current.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<maybe fix /etc/fstab> [7]
|
|
make buildworld
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
[1]
|
|
<reboot in single user> [3]
|
|
mergemaster -p [5]
|
|
make installworld
|
|
mergemaster [4]
|
|
<reboot>
|
|
|
|
|
|
To upgrade from 4.x-stable to current
|
|
-------------------------------------
|
|
# 5.x uses more space than 4.x. Also, the location of kernel
|
|
# modules has changed. If you are installing 5.0 onto a 4.x
|
|
# system, you'll need about 30MB of free disk space on your /
|
|
# partition. If you have less than this, you may encounter difficult
|
|
# to back out of problems with this proceedure. If /tmp is on
|
|
# the / partition, you may want to completely remove all its content
|
|
# before upgrading, as this can be a common source of shortage of
|
|
# space on /.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<maybe fix /etc/fstab> [7]
|
|
make buildworld [9]
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
|
|
cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
cd src/sys/boot ; make install [6]
|
|
[1]
|
|
<reboot in single user> [3]
|
|
mergemaster -p [5]
|
|
rm -rf /usr/include/g++
|
|
make installworld
|
|
mergemaster [4]
|
|
<reboot>
|
|
|
|
Make sure that you've read the UPDATING file to understand the
|
|
tweaks to various things you need. At this point in the life
|
|
cycle of current, things change often and you are on your own
|
|
to cope. The defaults can also change, so please read ALL of
|
|
the UPDATING entries.
|
|
|
|
Also, if you are tracking -current, you must be subscribed to
|
|
freebsd-current@freebsd.org. Make sure that before you update
|
|
your sources that you have read and understood all the recent
|
|
messages there. If in doubt, please track -stable which has
|
|
much fewer pitfalls.
|
|
|
|
[1] If you have third party modules, such as vmware, you
|
|
should disable them at this point so they don't crash your
|
|
system on reboot.
|
|
|
|
[2] If you have legacy ISA devices, you may need to create
|
|
your own device.hints to reflect your unique hardware
|
|
configuration.
|
|
|
|
[3] From the bootblocks, boot -s, and then do
|
|
fsck -p
|
|
mount -u /
|
|
mount -a
|
|
cd /usr/src
|
|
adjkerntz -i # if CMOS is wall time
|
|
Also, when doing a major release upgrade, it is required that
|
|
you boot into single user mode to do the installworld.
|
|
For the 4.x -> 5.0 upgrade, you will also see many messages about
|
|
needing to recompile your userland. These are harmless and can
|
|
be ignored while you proceed to the next step.
|
|
|
|
[4] Note: This step is non-optional. Failure to do this step
|
|
can result in a significant reduction in the functionality of the
|
|
system. Attempting to do it by hand is not recommended and those
|
|
that pursue this avenue should read this file carefully, as well
|
|
as the archives of freebsd-current and freebsd-hackers mailing lists
|
|
for potential gotchas.
|
|
|
|
[5] Usually this step is a noop. However, from time to time
|
|
you may need to do this if you get unknown user in the following
|
|
step. It never hurts to do it all the time. You may need to
|
|
install a new mergemaster (cd src/usr.sbin/mergemaster && make
|
|
install) after the buildworld before this step if you last updated
|
|
from current before 20020224 or from -stable before 20020408.
|
|
|
|
[6] 4.x boot loader can be used to boot a 5.x system, however
|
|
it is difficult to do that at best. If you wish to try, then
|
|
you should interrupt the boot and at the ok prompt type:
|
|
ok unload
|
|
ok boot /boot/kernel/kernel
|
|
If this fails to work, you must install a new boot loader as
|
|
described here.
|
|
|
|
[7] Before you upgrade, please make sure that you are not using
|
|
compatibility slices. These are device names of the form, on i386
|
|
and other architectures that use MBR slicing, /dev/ad0a without the
|
|
actual slice name. Chances are excellent that these will break.
|
|
You generally must update these entries to use the post FreeBSD
|
|
2.x form of /dev/ad0s1a.
|
|
|
|
[8] In order to have a kernel that can run the 4.x binaries
|
|
needed to do an installworld, you must include the COMPAT_FREEBSD4
|
|
option in your kernel. Failure to do so may leave you with a system
|
|
that is hard to boot to recover.
|
|
|
|
[9] When checking out sources, you must include the -P flag to have
|
|
cvs prune empty directories.
|
|
FORMAT:
|
|
|
|
This file contains a list, in reverse chronological order, of major
|
|
breakages in tracking -current. Not all things will be listed here,
|
|
and it only starts on March 15, 2000. Updating files can found in
|
|
previous releases if your system is older than this.
