compile option. All FreeBSD packet filters now use the PFIL_HOOKS API and thus it becomes a standard part of the network stack. If no hooks are connected the entire packet filter hooks section and related activities are jumped over. This removes any performance impact if no hooks are active. Both OpenBSD and DragonFlyBSD have integrated PFIL_HOOKS permanently as well.

NOTE TO PEOPLE WHO THINK THAT FreeBSD 6.x IS SLOW:
|
|
FreeBSD 6.x 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.
|
|
|
|
20040827:
|
|
PFIL_HOOKS are a fixed part of the network stack now and do not
|
|
need to be specified in the kernel configuration file anymore.
|
|
|
|
20040819:
|
|
Netgraph changed its message format slightly to align the data
|
|
portion well on 64 bit machines.
|
|
Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
|
|
pppoed, bluetooth, ATM) should be recompiled when a new kernel
|
|
is installed.
|
|
|
|
20040817:
|
|
IPFW has been converted to use PFIL_HOOKS. This change is
|
|
transparent to userland and preserves the ipfw ABI. The ipfw
|
|
core packet inspection and filtering functions have not been
|
|
changed, only how ipfw is invoked is different. Note that
|
|
"option PFIL_HOOKS" is required to use IPFIREWALL compiled
|
|
into the kernel or as KLD.
|
|
|
|
20040814:
|
|
The RANDOM_IP_ID option has been replaced by the sysctl
|
|
net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then
|
|
you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf.
|
|
|
|
20040807:
|
|
The size of 'struct ifnet' has changed due to the addition of the
|
|
if_carp placeholder. All kernel modules implementing network
|
|
interfaces must be recompiled as a result.
|
|
|
|
20040806:
|
|
Module loading has been fixed. Some older installations will
|
|
drop proper module_path initialization and modules will fail to
|
|
load properly. If you have a line in /boot/loader.rc that says:
|
|
"initialize drop", do (i386 only):
|
|
cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
|
|
chown root:wheel /boot/loader.rc
|
|
chmod 444 /boot/loader.rc
|
|
|
|
20040802:
|
|
making /dev/(null|zero) into a module proved to be too unpopular,
|
|
so this bit has been revoked from the previous (20040801) entry.
|
|
|
|
20040801:
|
|
The /dev/mem, /dev/io /dev/(null/zero) devices are now modules,
|
|
so you may wish to add them to your kernel config file. See
|
|
GENERIC for examples.
|
|
|
|
20040728:
|
|
System compiler has been upgraded to GCC 3.4.2-pre. As with any major
|
|
compiler upgrade, there are several issues to be aware of. GCC 3.4.x
|
|
has broken C++ ABI compatibility with previous releases yet again
|
|
and users will have to rebuild all their C++ programs with the new
|
|
compiler. If you are getting run-time error such as
|
|
/libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE"
|
|
This entry does apply to you.
|
|
|
|
A new unit-at-a-time optimization mode, which is default in this
|
|
compiler release, is more aggressive in removing unused static
|
|
symbols. This is the likely cause of 'make buildworld' breakages
|
|
with non-default CFLAGS where optimization level is set to -O2
|
|
or higher.
|
|
|
|
With the upgrade of the system compiler, the kernel has been upgraded
|
|
to match the new system compiler. This makes it impossible to build
|
|
a new kernel with the old compiler. Upgrade your system via
|
|
make buildworld and make kernel (see below) to fix this problem.
|
|
|
|
20040727:
|
|
The size of 'struct ifnet' has changed due to the addition of
|
|
the IFF_NEEDSGIANT flag (and what it implies). All kernel
|
|
modules implementing network interfaces must be recompiled as
|
|
a result.
|
|
|
|
20040716:
|
|
The sound device drivers are renamed. `sound' is always required,
|
|
while `snd_*' should be configured accordingly to your hardware.
|
|
Refer to NOTES for the detail of the drivers.
|
|
|
|
20040710:
|
|
__FreeBSD_version bumped to 502122.
|
|
|
|
20040710:
|
|
The console initialization on Alpha has been reworked and is now
|
|
identical to other platforms. This means that the hardcoding of
|
|
the serial console and the debug port has been removed. As such,
|
|
hints are now required for the sio(4) driver to become a console
|
|
or debug port. The NO_SIO option has been decommissioned because
|
|
of this.
|
|
|
|
20040710:
|
|
A revamp of the debugging code in the kernel with some visible
|
|
changes beyond just the debugging experience:
|
|
o The DDB option is now specific to the DDB debugger backend
|
|
and should not be used any more for conditional compilation
|
|
of debugging code for when debugging is enabled. Use the KDB
|
|
option for this.
|
|
o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have
|
|
been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED
|
|
respectively. This is in line with the first bullet.
|
|
o The remote GDB support has been untangled from DDB and needs
|
|
to be enabled separately now. Use the GDB option for this.
|
|
o The GDB_REMOTE_CHAT option has been removed. Support for this
|
|
homegrown feature is discontinued. The GDB remote protocol
|
|
supports console output and it makes sense to use that.
|
|
o The DDB_NOKLDSYM option has been removed. The DDB debugger
|
|
now supports both direct symbol table lookups as well as KLD
|
|
symbol lookups through the linker.
|
|
|
|
20040708:
|
|
Bluetooth code has been marked as non-i386 specific.
|
|
__FreeBSD_version has been bumped to 502121 to mark this change.
|
|
|
|
20040702:
|
|
The native preemption has been added to the kernel scheduler.
|
|
There is some report that the ULE scheduler was broken in some
|
|
machines and we encourage users using the ULE scheduler either
|
|
stick with a known good kernel, or temporarily switch to the 4BSD
|
|
scheduler as a workaround.
|
|
|
|
20040630:
|
|
The netgraph ABI version number has been incremented to indicate
|
|
an incompatible change in the ABI. Old netgraph nodes will refuse
|
|
to attach until recompiled. Netgraph now uses mbuf tags to move
|
|
metadata and this commit removes its home-grown metadata facility.
|
|
Nodes should just recompile, unless they use metadata, in which
|
|
case the changes are simple; the file ng_ksocket.c serves as an
|
|
example of such changes.
|
|
|
|
This also broke i4b, although the compile problem has been papered
|
|
over.
|
|
|
|
20040630:
|
|
ACPI has been updated to disable known-bad BIOS revisions. A message
|
|
will be printed on the console indicating that ACPI has been disabled
|
|
automatically and that the user should use a newer BIOS, if possible.
|
|
If you think ACPI does work on your system and want to override
|
|
this (i.e., for testing), set hint.acpi.0.disabled="0" at the
|
|
loader prompt.
|
|
|
|
20040623:
|
|
pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege
|
|
separated now. It uses the newly created "_pflogd" user/group
|
|
combination. If you plan to use pflogd(8) make sure to run
|
|
mergemaster -p or install the "_pflogd" user and group manually.
|
|
|
|
20040622:
|
|
Network interface cloning has been overhauled. This change will
|
|
require a recompile of modules using cloning and modification of
|
|
external ones to the new API. __FreeBSD_version has been bumped
|
|
to 502119 to mark this change. Additionally, users creating
|
|
stf(4) interfaces via "ifconfig stf" will need to update their
|
|
scripts as this will create an interface named "stf" instead of
|
|
"stf0" and ifconfig will not print "stf0" to stdout.
|
|
|
|
20040621:
|
|
On 20040524, the /etc/rc.d/nsswitch script was modified to
|
|
automatically create /etc/nsswitch.conf on startup if it did
|
|
not already exist. Unfortunately, an error in the man page
|
|
was carried over to the script, resulting in incorrect
|
|
nsswitch settings. The simplest remedy is to remove both
|
|
/etc/nsswitch.conf and /etc/host.conf; they will be recreated
|
|
during the next reboot.
|
|
|
|
20040614:
|
|
The return value of sema_timedwait(9) has been changed to
|
|
make it consistent with cv_timedwait(9). Be sure to recompile
|
|
the ips module and any third-party modules which call
|
|
sema_timedwait.
|
|
|
|
20040613:
|
|
ALTQ is now linked to the build. This breaks ABI for struct ifnet.
|
|
Make sure to recompile modules and any userland that makes use of
|
|
sizeof(struct ifnet). In order to get the altq headers in place
|
|
please recompile and reinstall world.
|
|
|
|
20040607:
|
|
Splitting kern_thread.c into 2 files (adding kern_kse.c)
|
|
requires that you re-run config after updating your tree.
|
|
|
|
20040601:
|
|
The MIDI drivers have been removed. Until the new module-friendly
|
|
ones are merged, remove or comment out midi and seq from your
|
|
kernel configuration.
|
|
|
|
20040423:
|
|
Due to a new option in ipfw (versrcreach) the ipfw(8) command
|
|
needs to be recompiled. Normal accept/reject rules without
|
|
options are not affected but those with options may break until
|
|
ipfw(8) is recompiled.
|
|
|
|
20040420:
|
|
Due to changes in the callout ABI, kernels compiled after this
|
|
date may be incompatible with kernel modules compiled prior to
|
|
20040406.
|
|
|
|
20040414:
|
|
The PCI bus power state stuff has been turned on. If this causes
|
|
problems for your system, please disable it using the tunable
|
|
hw.pci.do_powerstate=0.
|
|
|
|
20040412:
|
|
The bulk of the pci problems have been fixed, although the floppy
|
|
drive is still broken.
|
|
|
|
20040410:
|
|
A substantial update to the pci bus resource and power management
|
|
have been committed. Expect a bumpy ride for a few days until
|
|
the unanticipated problems have been resolved.
|
|
|
|
20040409:
|
|
Due to changes in the the Yarrow initialization process,
|
|
/dev/random needs to be fed before operations requiring
|
|
temp files can succeed in single user mode. This includes
|
|
running "make installworld". /dev/random may be fed by running
|
|
"/etc/rc.d/initrandom start" or with 20040415 source by running
|
|
"/etc/rc.d/preseedrandom".
|
|
|
|
20040322:
|
|
The debug.mpsafenet tunable controls whether the kernel Giant
|
|
lock is held across the lower levels of the network stack, and
|
|
by default is turned off. In the few days following 20040322,
|
|
the behavior of debug.mpsafenet will change such that this
|
|
tunable controls Giant over all levels of the network stack.
|
|
If you are currently setting debug.mpsafenet to 1, you should
|
|
set it back to 0 (the default) again during the change-over.
|
|
An additional note will be added to UPDATING when sufficient
|
|
locking is merged to permit this to take place.
|
|
|
|
20040310:
|
|
The FreeBSD/sparc64 platform is changing time_t from 32-bits to
|
|
64-bits. This is a very major incompatible change, so people
|
|
using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for
|
|
detailed instructions on how to make this upgrade. People
|
|
upgrading FreeBSD on other platforms can ignore this event.
|
|
|
|
20040308:
|
|
The packet filter (pf) is now installed with the base system. Make
|
|
sure to run mergemaster -p before installworld to create required
|
|
user account ("proxy"). If you do not want to build pf with your
|
|
system you can use the NO_PF knob in make.conf.
|
|
Also note that pf requires "options PFIL_HOOKS" in the kernel. The
|
|
pf system consists of the following three devices:
|
|
device pf # required
|
|
device pflog # optional
|
|
device pfsync # optional
|
|
|
|
20040303:
|
|
If you are having trouble with the libc_r -> libpthread transition
|
|
(see the 20040130 entry), place the following lines at the top of
|
|
/etc/libmap.conf:
|
|
|
|
libc_r.so.5 libpthread.so.1
|
|
libc_r.so libpthread.so
|
|
|
|
This will cause all programs and libraries linked against libc_r
|
|
to use libpthread instead.
|
|
|
|
20040226:
|
|
Some sshd configuration defaults have changed: protocol version 1
|
|
is no longer enabled by default, and password authentication is
|
|
disabled by default if PAM is enabled (which it is by default).
|
|
OpenSSH clients should not be affected by this; other clients may
|
|
have to be reconfigured, upgraded or replaced.
|
|
|
|
20040225:
|
|
The ABIs defined in <resolv.h> and <netdb.h> have been updated
|
|
to support improved reentrancy. Multi-threaded programs that
|
|
reference the "_res" or "h_errno" symbols may experience some
|
|
problems if they are not recompiled. Single-threaded programs
|
|
should remain unaffected.
|
|
|
|
20040225:
|
|
routed has been updated in the base system from the vendor
|
|
sources, routed v2.27, from rhyolite.com. This change means that
|
|
for users who use RIP's MD5 authentication feature, FreeBSD
|
|
-CURRENT's routed is now incompatible with previous versions
|
|
of FreeBSD; however it is now compatible with implementations
|
|
from Sun, Cisco and other vendors.
|
|
|
|
20040224:
|
|
The tcpcb structure has changed and makes a recompile of libkvm
|
|
and related userland network utilities necessary.
|
|
|
|
20040222:
|
|
The cdevsw structure has changed in two externally visible ways.
|
|
First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT.
|
|
Second, the d_version field must be filled in with D_VERSION.
|
|
Drivers outside the tree will need to be updated.
|
|
|
|
20040207:
|
|
The /etc/rc.d/ttys script has been removed. It is no longer
|
|
necessary since devfs has been mandatory for some time.
|
|
|
|
20040130:
|
|
libkse has been renamed back to libpthread and is now the
|
|
default threads library. The gcc -pthread option has also
|
|
been changed to link to libpthread instead of libc_r. For
|
|
alpha and sparc64 machines, libkse is not renamed and links
|
|
are installed so that libpthread points to libc_r. Until
|
|
the ports system is updated to handle this change, it is
|
|
recommended that folks install an /etc/libmap.conf(5) that
|
|
maps libc_r to libpthread. If you have any binaries or
|
|
libraries linked to libkse, then it is also recommended
|
|
that you map libkse to libpthread. Anyone that is using
|
|
nvidia supplied drivers and libraries should use a libmap.conf
|
|
that maps libpthread to libc_r since their drivers/libraries
|
|
do not work with libpthread.
|
|
|
|
20040125:
|
|
ULE has entered into its probationary period as the default scheduler
|
|
in GENERIC. For the average user, interactivity is reported to be
|
|
better in many cases. On SMP machines ULE will be able to make more
|
|
efficient use of the available parallel resources. If you are not
|
|
running it now, please switch over, replacing the kernel option
|
|
SCHED_4BSD with SCHED_ULE.
|
|
|
|
20040125:
|
|
Move LongRun support out of identcpu.c, where it hardly
|
|
belongs, into its own file and make it opt-in, not mandatory,
|
|
depending on CPU_ENABLE_LONGRUN config(8) option.
|
|
|
|
20031213:
|
|
src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail
|
|
if the login process is unable to successfully set the
|
|
process credentials to include all groups defined for the
|
|
user. The current kernel limit is 16 groups; administrators
|
|
may wish to check that users do not have over 16 groups
|
|
defined, or they will be unable to log in.
|
|
|
|
20031203:
|
|
The ACPI module has been reactivated. It is no longer required
|
|
to compile ACPI support into kernels statically.
|
|
|
|
20031112:
|
|
The statfs structure has been updated with 64-bit fields to
|
|
allow accurate reporting of multi-terabyte filesystem
|
|
sizes. You should build world, then build and boot the new kernel
|
|
BEFORE doing a `installworld' as the new kernel will know about
|
|
binaries using the old statfs structure, but an old kernel will
|
|
not know about the new system calls that support the new statfs
|
|
structure.
|
|
Note that the backwards compatibility is only present when the
|
|
kernel is configured with the COMPAT_FREEBSD4 option. Since
|
|
even /bin/sh will not run with a new kernel without said option
|
|
you're pretty much dead in the water without it. Make sure you
|
|
have COMPAT_FREEBSD4!
|
|
Running an old kernel after a `make world' will cause programs
|
|
such as `df' that do a statfs system call to fail with a bad
|
|
system call. Marco Wertejuk <wertejuk@mwcis.com> also reports
|
|
that cfsd (ports/security/cfs) needs to be recompiled after
|
|
these changes are installed.
|
|
|
|
****************************DANGER*******************************
|
|
|
|
DO NOT make installworld after the buildworld w/o building and
|
|
installing a new kernel FIRST. You will be unable to build a
|
|
new kernel otherwise on a system with new binaries and an old
|
|
kernel.
|
|
|
|
20031112:
|
|
Some netgraph string length constants have been changed. This
|
|
change requires the netgraph kernel modules and all netgraph
|
|
userland components to be in sync. Especially users who require
|
|
netgraph to boot need to make sure to have world and kernel in
|
|
sync before rebooting.
|
|
|
|
20031111:
|
|
Hyperthreading logical CPU's are no longer probed by default
|
|
when using the MP Table. If ACPI is being used, then logical
|
|
CPUs will be probed if hyperthreading is enabled in the BIOS.
|
|
If ACPI is not being used and hyperthreading is enabled in the
|
|
BIOS, logical CPUs can be enabled by building a custom kernel
|
|
with the option MPTABLE_FORCE_HTT enabled.
|
|
|
|
20031103:
|
|
The i386 APIC_IO kernel option has been replaced by
|
|
'device apic'. The ACPI module has also been temporarily
|
|
disabled, so ACPI must be statically compiled into your
|
|
kernel using 'device acpi' if you wish to use the ACPI driver.
|
|
|
|
20031031:
|
|
The API and ABI of struct ifnet have been changed by removing
|
|
the if_name and if_unit members and replacing them with
|
|
if_xname, if_dname, and if_dunit. All network drivers and most
|
|
userland programs which include net/if_var.h must be updated
|
|
and recompiled. __FreeBSD_version has been bumped to 501113 to
|
|
reflect this change.
|
|
|
|
20030928:
|
|
Changes to the cdevsw default functions have been made to remove
|
|
the need to specify nullopen() and nullclose() explicitly.
|
|
__FreeBSD_version bumped to 501110.
|
|
|
|
20030926:
|
|
kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and
|
|
mount_cd9660(8) need to be in sync with kernel.
|
|
|
|
20030925:
|
|
Configuring a system to use IPFILTER now requires that PFIL_HOOKS
|
|
also be explicitly configured. Previously this dependency was
|
|
magically handled through some cruft in net/pfil.h; but that has
|
|
been removed. Building a kernel with IPFILTER but not PFIL_HOOKS
|
|
will fail with obtuse errors in ip_fil.c.
|
|
|
|
20030923:
|
|
Fix a bug in arplookup(), whereby a hostile party on a locally
|
|
attached network could exhaust kernel memory, and cause a system
|
|
panic, by sending a flood of spoofed ARP requests. See
|
|
FreeBSD-SA-03:14.arp.
|
|
|
|
20030915:
|
|
A change to /etc/defaults/rc.conf now causes inetd to be started
|
|
with `-C 60' if it is not overridden in /etc/rc.conf. This
|
|
causes inetd to stop accepting connections from an IP address
|
|
that exceeds the rate of 60 connections per minute.
|
|
|
|
20030829:
|
|
The following rc.d scripts have been removed and should be
|
|
deleted from your installation: atm2.sh atm3.sh devdb
|
|
localdaemons network1 network2 network3. Depending on when
|
|
you last updated world and used mergemaster(8) you may or
|
|
may not have problems during the rc boot sequence. The simplest
|
|
solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'.
|
|
The atm2.sh atm3.sh and devdb scripts were removed some time
|
|
ago, so depending on when you installed -CURRENT these scripts
|
|
may or may not exist on your system.
|
|
|
|
20030824:
|
|
ATAng has been committed. You need to build world as sys/ata.h
|
|
has changed, and userland atacontrol depends on it.
|
|
If you use ATA SW raids you need "device ataraid" in your
|
|
kernel config file, as it is no longer pulled in automatically.
|
|
|
|
20030819:
|
|
The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel.
|
|
Among other things, this changes the device enumeration to be
|
|
closer to Solaris. Be aware that, this can even cause the machine
|
|
to not boot without manual intervention before the fstab is adjusted.
|
|
|
|
20030728:
|
|
All current USB and Firewire quirks in da(4) have been deprecated
|
|
and will be removed for 5.2. If this causes failure for your
|
|
umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel
|
|
and send the output of "camcontrol inquiry da0" to scsi@freebsd.org
|
|
so the quirk can be re-enabled.
|
|
|
|
20030724:
|
|
Problems with entry 20030714 have been corrected and no known issues
|
|
with /rescue and -j exist for host systems after this point in time.
|
|
|
|
20030722:
|
|
FPU-less support has been removed from FreeBSD. Chances are you won't
|
|
notice. 386+387 support should still work after this change, but
|
|
it is now a minimum requirement for the i386 port that you have real
|
|
FPU hardware.
|
|
|
|
20030714:
|
|
Some people are having problems with changes related to /rescue.
|
|
If you are building -j N, you will need to define NO_RESCUE. Others
|
|
will need to define it if /rescue has issues with their environment.
|
|
People should report those issues to current@.
|
|
|
|
20030711:
|
|
gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN
|
|
across this point. Further, it might be a good idea to remove
|
|
/usr/obj.
|
|
|
|
20030610:
|
|
Remove deprecated locale names and transition period code
|
|
for them, finishing switching to the new scheme. Check your
|
|
LANG environment variable.
|
|
|
|
20030609:
|
|
CCD has been changed to be a fully GEOMified class. Kernel
|
|
and ccdconfig(8) needs to be in sync, this is particularly
|
|
important to remember beforehand if your source tree is on
|
|
a ccd device. Consider making a copy of the old ccdconfig
|
|
into /boot/kernel.good or wherever you keep your backup
|
|
kernel.
|
|
|
|
20030605:
|
|
There was a small window in which sed(1) was broken. If you
|
|
happen to have sed(1) installed during that window, which is
|
|
evidenced by an inability to build world with the failure
|
|
given below, you need to manually build and install sed(1)
|
|
(and only sed(1)) before doing anything else. This is a one-
|
|
time snafu. Typical failure mode:
|
|
|
|
In file included from /usr/src/contrib/binutils/bfd/targets.c:1092:
|
|
targmatch.h:7:1: null character(s) ignored
|
|
targmatch.h:12:1: null character(s) ignored
|
|
targmatch.h:16:1: null character(s) ignored
|
|
:
|
|
|
|
The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC
|
|
to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of
|
|
usr.bin/sed/process.c).
|
|
|
|
20030505:
|
|
Kerberos 5 (Heimdal) is now built by default. Setting
|
|
MAKE_KERBEROS5 no longer has any effect. If you do NOT
|
|
want the "base" Kerberos 5, you need to set NO_KERBEROS.
|
|
|
|
20030502:
|
|
groff has been updated. If you try to do a buildworld and
|
|
get an infinite loop in troff, update to May 4th or newer. If you
|
|
have a newer kernel than userland, you may need to set the OSRELDATE
|
|
to 500110 in your environment before starting a buildworld.
|
|
|
|
20030501:
|
|
The old rc system has been removed. Please report any problems
|
|
to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org.
|
|
Your personal versions of these files will not be removed, so you can
|
|
continue to use them. However, you should take great care when updating,
|
|
especially when using mergemaster, since the compatibility code that
|
|
utilizes these old scripts has also been removed.
|
|
|
|
20030423:
|
|
A bug has been fixed in /dev/devctl which would cause devd
|
|
to hang on boot, were it not for a workaround in devd. The
|
|
work around in devd will be removed around 20030507. You
|
|
have until then to upgrade your kernel before updating
|
|
userland. In general, you should have a userland and
|
|
kernel that's in sync with each other. However, given the
|
|
effects of this bug (hang on boot when starting devd), some
|
|
allowances are made.
|
|
|
|
20030329:
|
|
Alphas with libc from between 20030312 and 20030329 exhibit
|
|
floating point exceptions (FPEs), most notably in awk(1)
|
|
while upgrading the system through a buildworld.
|
|
|
|
So, to successfully upgrade your Alpha, you must either
|
|
downgrade your libc.so to a pre-20030312 version, or update
|
|
/usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee
|
|
to CFLAGS, then forcibly rebuild and install libc:
|
|
|
|
cd /usr/src/lib/libc && \
|
|
make cleandir && make obj && \
|
|
make -DNOMAN -DNOPROFILE all && \
|
|
make -DNOMAN -DNOPROFILE install
|
|
|
|
20030208:
|
|
sendmail 8.12.7 has been imported. It has one important
|
|
change for IPv6 users. The default submit.mc now uses
|
|
'[127.0.0.1]' instead of 'localhost' meaning only IPv4 is
|
|
used to connect to the MTA. Users on IPv6-only machines
|
|
will need to edit /etc/mail/submit.mc appropriately.
|
|
|
|
20030128:
|
|
NODEVFS option has been removed and DEVFS thereby made standard.
|
|
This makes all references to MAKEDEV obsolete, and they should
|
|
be removed when convenient.
|
|
|
|
20030126:
|
|
The name of the device for the ofw console has changed, sparc64 users
|
|
must run mergemaster to update their installed /etc/ttys.
|
|
|
|
20030125:
|
|
The scheduler framework has grown a second scheduler and consequently
|
|
you must specify one and only one scheduler in your kernel config.
|
|
The 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 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. (This doesn't affect the disks formatted in
|
|
the ``dangerously-dedicated'' mode.)
|
|
|
|
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.

|
|
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 bug fixes 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.disabled="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, whether 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 damage 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

|
|
|
|
20010520:
|
|
Vm and/or swapping are busted on -current. Please be patient.
|
|
|
|
20010519:
|
|
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:

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_ENABLE_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 kernel 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 silliness 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
|

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.

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:
|
|
cd /sys/<ARCH>/conf && make LINT
|
|
|
|
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).
|
|
|
|
20000612:
|
|
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.
|
|
|
|
20000522:
|
|
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.
|
|
|
|
20000427:
|
|
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:
|
|
|
|
# NOTE: 5.x below applies to 6.0-currrent as well, for the
|
|
# momemnt. 4.any -> 5.any upgrade support will remain in
|
|
# place for 6.0 current, but after 5.3 RELEASE, the 4.any ->
|
|
# 6.0-current upgrade path will require moving through 5.3
|
|
# RELEASE or newer.
|
|
|
|
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 -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
|
|
To just build a kernel when you know that it won't mess you up
|
|
--------------------------------------------------------------
|
|
This assumes you are already running a 5.X system. Replace
|
|
${arch} with the architecture of your machine (e.g. "i386",
|
|
"alpha", "amd64", "ia64", "pc98", "sparc64", etc).
|
|
|
|
cd src/sys/${arch}/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]
|

<reboot>
|
|
|
|
|
|
To cross-install current onto a separate partition
|
|
--------------------------------------------------
|
|
# In this approach we use a separate partition to hold
|
|
# current's root, 'usr', and 'var' directories. A partition
|
|
# holding "/", "/usr" and "/var" should be about 2GB in
|
|
# size.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<boot into -stable>
|
|
make buildworld
|
|
<maybe newfs current's root partition>
|
|
<mount current's root partition on directory ${CURRENT_ROOT}>
|
|
make installworld DESTDIR=${CURRENT_ROOT}
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
cp src/sys/${ARCH}/conf/GENERIC.hints \
|
|
${CURRENT_ROOT}/boot/device.hints # as needed
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
|
|
cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
|
|
cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
|
|
<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
|
|
<reboot into current>
|
|
<do a "native" rebuild/install as described in the previous section>
|
|
<maybe install compatibility libraries from src/lib/compat>
|
|
<reboot>
|
|
|
|
|
|
To upgrade in-place from 4.x-stable to current
|
|
----------------------------------------------
|
|
# 5.x uses more space than 4.x. Also, the location of kernel
|
|
# modules has changed. If you are installing 5.0 onto a 4.x
|
|
# system, you'll need about 30MB of free disk space on your /
|
|
# partition. If you have less than this, you may encounter difficult
|
|
# to back out of problems with this procedure. If /tmp is on
|
|
# the / partition, you may want to completely remove all its content
|
|
# before upgrading, as this can be a common source of shortage of
|
|
# space on /.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<maybe fix /etc/fstab> [7]
|
|
make buildworld [9]
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
|
|
cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
cd sys/boot ; make STRIP="" install [6]
|
|

|
|
<reboot in single user> [3]

|
|

|
|

|
|

|
|
mergemaster -i [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 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.x 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. Also, if CPUTYPE is defined in your
|
|
/etc/make.conf, make sure to use the "?=" instead of the "=" assignment
|
|
operator, so that buildworld can override the CPUTYPE if it needs to.
|
|
In case you would like to avoid installing new packages of everything,
|
|
you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x
|
|
compatibility libraries are built which should allow you to continue
|
|
using your existing software for a while.
|
|
|
|
[10] In order to create temporary files, /dev/random must be
|
|
initialized by feeding data into it. src/etc/rc.d/preseedrandom
|
|
takes care of this.
|
|
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.
