Updating Information for FreeBSD current users
This file is maintained and copyrighted by M. Warner Losh <[email protected]>.
See end of file for further details. For commonly done items, please see the
COMMON ITEMS: section later in the file. These instructions assume that you
basically know what you are doing. If not, then please consult the FreeBSD
handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
Items affecting the ports and packages system can be found in
/usr/ports/UPDATING. Please read that file before running portupgrade.
NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
from older versions of FreeBSD, try WITHOUT_CLANG to bootstrap to the tip of
head, and then rebuild without this option. The bootstrap process from
older version of current is a bit fragile.
NOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW:
FreeBSD 11.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. (To completely disable malloc
debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
disable the most expensive debugging functionality run
"ln -s 'abort:false,junk:false' /etc/malloc.conf".)
20140128:
The libelf and libdwarf libraries have been updated to newer
versions from upstream. Shared library version numbers for
these two libraries were bumped. Any ports or binaries
requiring these two libraries should be recompiled.
__FreeBSD_version is bumped to 1100006.
20140110:
If a Makefile in a tests/ directory was auto-generating a Kyuafile
instead of providing an explicit one, this would prevent such
Makefile from providing its own Kyuafile in the future during
NO_CLEAN builds. This has been fixed in the Makefiles but manual
intervention is needed to clean an objdir if you use NO_CLEAN:
# find /usr/obj -name Kyuafile | xargs rm -f
20131213:
The behavior of gss_pseudo_random() for the krb5 mechanism
has changed, for applications requesting a longer random string
than produced by the underlying enctype's pseudo-random() function.
In particular, the random string produced from a session key of
enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
be different at the 17th octet and later, after this change.
The counter used in the PRF+ construction is now encoded as a
big-endian integer in accordance with RFC 4402.
__FreeBSD_version is bumped to 1100004.
20131108:
The WITHOUT_ATF build knob has been removed and its functionality
has been subsumed into the more generic WITHOUT_TESTS. If you were
using the former to disable the build of the ATF libraries, you
should change your settings to use the latter.
20131025:
The default version of mtree is nmtree which is obtained from
NetBSD. The output is generally the same, but may vary
slightly. If you found you need identical output adding
"-F freebsd9" to the command line should do the trick. For the
time being, the old mtree is available as fmtree.
20131014:
libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
1.1.4_8 and verify bsdyml not linked in, before running "make
delete-old-libs":
# make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
or
# pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
20131010:
The rc.d/jail script has been updated to support jail(8)
configuration file. The "jail_<jname>_*" rc.conf(5) variables
for per-jail configuration are automatically converted to
/var/run/jail.<jname>.conf before the jail(8) utility is invoked.
This is transparently backward compatible. See below about some
incompatibilities and rc.conf(5) manual page for more details.
These variables are now deprecated in favor of jail(8) configuration
file. One can use "rc.d/jail config <jname>" command to generate
a jail(8) configuration file in /var/run/jail.<jname>.conf without
running the jail(8) utility. The default pathname of the
configuration file is /etc/jail.conf and can be specified by
using $jail_conf or $jail_<jname>_conf variables.
Please note that jail_devfs_ruleset accepts an integer at
this moment. Please consider to rewrite the ruleset name
with an integer.
20130930:
BIND has been removed from the base system. If all you need
is a local resolver, simply enable and start the local_unbound
service instead. Otherwise, several versions of BIND are
available in the ports tree. The dns/bind99 port is one example.
With this change, nslookup(1) and dig(1) are no longer in the base
system. Users should instead use host(1) and drill(1) which are
in the base system. Alternatively, nslookup and dig can
be obtained by installing the dns/bind-tools port.
20130916:
With the addition of unbound(8), a new unbound user is now
required during installworld. "mergemaster -p" can be used to
add the user prior to installworld, as documented in the handbook.
20130911:
OpenSSH is now built with DNSSEC support, and will by default
silently trust signed SSHFP records. This can be controlled with
the VerifyHostKeyDNS client configuration setting. DNSSEC support
can be disabled entirely with the WITHOUT_LDNS option in src.conf.
20130906:
The GNU Compiler Collection and C++ standard library (libstdc++)
are no longer built by default on platforms where clang is the system
compiler. You can enable them with the WITH_GCC and WITH_GNUCXX
options in src.conf.
20130905:
The PROCDESC kernel option is now part of the GENERIC kernel
configuration and is required for the rwhod(8) to work.
If you are using custom kernel configuration, you should include
'options PROCDESC'.
20130905:
The API and ABI related to the Capsicum framework was modified
in backward incompatible way. The userland libraries and programs
have to be recompiled to work with the new kernel. This includes the
following libraries and programs, but the whole buildworld is
advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl,
kdump, procstat, rwho, rwhod, uniq.
20130903:
AES-NI intrinsic support has been added to gcc. The AES-NI module
has been updated to use this support. A new gcc is required to build
the aesni module on both i386 and amd64.
20130821:
The PADLOCK_RNG and RDRAND_RNG kernel options are now devices.
Thus "device padlock_rng" and "device rdrand_rng" should be
used instead of "options PADLOCK_RNG" & "options RDRAND_RNG".
20130813:
WITH_ICONV has been split into two feature sets. WITH_ICONV now
enables just the iconv* functionality and is now on by default.
WITH_LIBICONV_COMPAT enables the libiconv api and link time
compatability. Set WITHOUT_ICONV to build the old way.
If you have been using WITH_ICONV before, you will very likely
need to turn on WITH_LIBICONV_COMPAT.
20130806:
INVARIANTS option now enables DEBUG for code with OpenSolaris and
Illumos origin, including ZFS. If you have INVARIANTS in your
kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG
explicitly.
DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS)
locks if WITNESS option was set. Because that generated a lot of
witness(9) reports and all of them were believed to be false
positives, this is no longer done. New option OPENSOLARIS_WITNESS
can be used to achieve the previous behavior.
20130806:
Timer values in IPv6 data structures now use time_uptime instead
of time_second. Although this is not a user-visible functional
change, userland utilities which directly use them---ndp(8),
rtadvd(8), and rtsold(8) in the base system---need to be updated
to r253970 or later.
20130802:
find -delete can now delete the pathnames given as arguments,
instead of only files found below them or if the pathname did
not contain any slashes. Formerly, the following error message
would result:
find: -delete: <path>: relative path potentially not safe
Deleting the pathnames given as arguments can be prevented
without error messages using -mindepth 1 or by changing
directory and passing "." as argument to find. This works in the
old as well as the new version of find.
20130726:
Behavior of devfs rules path matching has been changed.
Pattern is now always matched against fully qualified devfs
path and slash characters must be explicitly matched by
slashes in pattern (FNM_PATHNAME). Rulesets involving devfs
subdirectories must be reviewed.
20130716:
The default ARM ABI has changed to the ARM EABI. The old ABI is
incompatible with the ARM EABI and all programs and modules will
need to be rebuilt to work with a new kernel.
To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set.
NOTE: Support for the old ABI will be removed in the future and
users are advised to upgrade.
20130709:
pkg_install has been disconnected from the build if you really need it
you should add WITH_PKGTOOLS in your src.conf(5).
20130709:
Most of network statistics structures were changed to be able
keep 64-bits counters. Thus all tools, that work with networking
statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.)
20130629:
Fix targets that run multiple make's to use && rather than ;
so that subsequent steps depend on success of previous.
NOTE: if building 'universe' with -j* on stable/8 or stable/9
it would be better to start the build using bmake, to avoid
overloading the machine.
20130618:
Fix a bug that allowed a tracing process (e.g. gdb) to write
to a memory-mapped file in the traced process's address space
even if neither the traced process nor the tracing process had
write access to that file.
20130615:
CVS has been removed from the base system. An exact copy
of the code is available from the devel/cvs port.
20130613:
Some people report the following error after the switch to bmake:
make: illegal option -- J
usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable]
...
*** [buildworld] Error code 2
this likely due to an old instance of make in
${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE})
which src/Makefile will use that blindly, if it exists, so if
you see the above error:
rm -rf `make -V MAKEPATH`
should resolve it.
20130516:
Use bmake by default.
Whereas before one could choose to build with bmake via
-DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old
make. The goal is to remove these knobs for 10-RELEASE.
It is worth noting that bmake (like gmake) treats the command
line as the unit of failure, rather than statements within the
command line. Thus '(cd some/where && dosomething)' is safer
than 'cd some/where; dosomething'. The '()' allows consistent
behavior in parallel build.
20130429:
Fix a bug that allows NFS clients to issue READDIR on files.
20130426:
The WITHOUT_IDEA option has been removed because
the IDEA patent expired.
20130426:
The sysctl which controls TRIM support under ZFS has been renamed
from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been
enabled by default.
20130425:
The mergemaster command now uses the default MAKEOBJDIRPREFIX
rather than creating it's own in the temporary directory in
order allow access to bootstrapped versions of tools such as
install and mtree. When upgrading from version of FreeBSD where
the install command does not support -l, you will need to
install a new mergemaster command if mergemaster -p is required.
This can be accomplished with the command (cd src/usr.sbin/mergemaster
&& make install).
20130404:
Legacy ATA stack, disabled and replaced by new CAM-based one since
FreeBSD 9.0, completely removed from the sources. Kernel modules
atadisk and atapi*, user-level tools atacontrol and burncd are
removed. Kernel option `options ATA_CAM` is now permanently enabled
and removed.
20130319:
SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2)
and socketpair(2). Software, in particular Kerberos, may
automatically detect and use these during building. The resulting
binaries will not work on older kernels.
20130308:
CTL_DISABLE has also been added to the sparc64 GENERIC (for further
information, see the respective 20130304 entry).
20130304:
Recent commits to callout(9) changed the size of struct callout,
so the KBI is probably heavily disturbed. Also, some functions
in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced
by macros. Every kernel module using it won't load, so rebuild
is requested.
The ctl device has been re-enabled in GENERIC for i386 and amd64,
but does not initialize by default (because of the new CTL_DISABLE
option) to save memory. To re-enable it, remove the CTL_DISABLE
option from the kernel config file or set kern.cam.ctl.disable=0
in /boot/loader.conf.
20130301:
The ctl device has been disabled in GENERIC for i386 and amd64.
This was done due to the extra memory being allocated at system
initialisation time by the ctl driver which was only used if
a CAM target device was created. This makes a FreeBSD system
unusable on 128MB or less of RAM.
20130208:
A new compression method (lz4) has been merged to -HEAD. Please
refer to zpool-features(7) for more information.
Please refer to the "ZFS notes" section of this file for information
on upgrading boot ZFS pools.
20130129:
A BSD-licensed patch(1) variant has been added and is installed
as bsdpatch, being the GNU version the default patch.
To inverse the logic and use the BSD-licensed one as default,
while having the GNU version installed as gnupatch, rebuild
and install world with the WITH_BSD_PATCH knob set.
20130121:
Due to the use of the new -l option to install(1) during build
and install, you must take care not to directly set the INSTALL
make variable in your /etc/make.conf, /etc/src.conf, or on the
command line. If you wish to use the -C flag for all installs
you may be able to add INSTALL+=-C to /etc/make.conf or
/etc/src.conf.
20130118:
The install(1) option -M has changed meaning and now takes an
argument that is a file or path to append logs to. In the
unlikely event that -M was the last option on the command line
and the command line contained at least two files and a target
directory the first file will have logs appended to it. The -M
option served little practical purpose in the last decade so its
use is expected to be extremely rare.
20121223:
After switching to Clang as the default compiler some users of ZFS
on i386 systems started to experience stack overflow kernel panics.
Please consider using 'options KSTACK_PAGES=4' in such configurations.
20121222:
GEOM_LABEL now mangles label names read from file system metadata.
Mangling affect labels containing spaces, non-printable characters,
'%' or '"'. Device names in /etc/fstab and other places may need to
be updated.
20121217:
By default, only the 10 most recent kernel dumps will be saved. To
restore the previous behaviour (no limit on the number of kernel dumps
stored in the dump directory) add the following line to /etc/rc.conf:
savecore_flags=""
20121201:
With the addition of auditdistd(8), a new auditdistd user is now
required during installworld. "mergemaster -p" can be used to
add the user prior to installworld, as documented in the handbook.
20121117:
The sin6_scope_id member variable in struct sockaddr_in6 is now
filled by the kernel before passing the structure to the userland via
sysctl or routing socket. This means the KAME-specific embedded scope
id in sin6_addr.s6_addr[2] is always cleared in userland application.
This behavior can be controlled by net.inet6.ip6.deembed_scopeid.
__FreeBSD_version is bumped to 1000025.
20121105:
On i386 and amd64 systems WITH_CLANG_IS_CC is now the default.
This means that the world and kernel will be compiled with clang
and that clang will be installed as /usr/bin/cc, /usr/bin/c++,
and /usr/bin/cpp. To disable this behavior and revert to building
with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions
of current may need to bootstrap WITHOUT_CLANG first if the clang
build fails (its compatibility window doesn't extend to the 9 stable
branch point).
20121102:
The IPFIREWALL_FORWARD kernel option has been removed. Its
functionality now turned on by default.
20121023:
The ZERO_COPY_SOCKET kernel option has been removed and
split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP.
NB: SOCKET_SEND_COW uses the VM page based copy-on-write
mechanism which is not safe and may result in kernel crashes.
NB: The SOCKET_RECV_PFLIP mechanism is useless as no current
driver supports disposeable external page sized mbuf storage.
Proper replacements for both zero-copy mechanisms are under
consideration and will eventually lead to complete removal
of the two kernel options.
20121023:
The IPv4 network stack has been converted to network byte
order. The following modules need to be recompiled together
with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4),
pf(4), ipfw(4), ng_ipfw(4), stf(4).
20121022:
Support for non-MPSAFE filesystems was removed from VFS. The
VFS_VERSION was bumped, all filesystem modules shall be
recompiled.
20121018:
All the non-MPSAFE filesystems have been disconnected from
the build. The full list includes: codafs, hpfs, ntfs, nwfs,
portalfs, smbfs, xfs.
20121016:
The interface cloning API and ABI has changed. The following
modules need to be recompiled together with kernel:
ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4),
vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4),
faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4).
20121015:
The sdhci driver was split in two parts: sdhci (generic SD Host
Controller logic) and sdhci_pci (actual hardware driver).
No kernel config modifications are required, but if you
load sdhc as a module you must switch to sdhci_pci instead.
20121014:
Import the FUSE kernel and userland support into base system.
20121013:
The GNU sort(1) program has been removed since the BSD-licensed
sort(1) has been the default for quite some time and no serious
problems have been reported. The corresponding WITH_GNU_SORT
knob has also gone.
20121006:
The pfil(9) API/ABI for AF_INET family has been changed. Packet
filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled
with new kernel.
20121001:
The net80211(4) ABI has been changed to allow for improved driver
PS-POLL and power-save support. All wireless drivers need to be
recompiled to work with the new kernel.
20120913:
The random(4) support for the VIA hardware random number
generator (`PADLOCK') is no longer enabled unconditionally.
Add the padlock_rng device in the custom kernel config if
needed. The GENERIC kernels on i386 and amd64 do include the
device, so the change only affects the custom kernel
configurations.
20120908:
The pf(4) packet filter ABI has been changed. pfctl(8) and
snmp_pf module need to be recompiled to work with new kernel.
20120828:
A new ZFS feature flag "com.delphix:empty_bpobj" has been merged
to -HEAD. Pools that have empty_bpobj in active state can not be
imported read-write with ZFS implementations that do not support
this feature. For more information read the zpool-features(5)
manual page.
20120727:
The sparc64 ZFS loader has been changed to no longer try to auto-
detect ZFS providers based on diskN aliases but now requires these
to be explicitly listed in the OFW boot-device environment variable.
20120712:
The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring
libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are
configuration changes. Make sure to merge /etc/ssl/openssl.cnf.
20120712:
The following sysctls and tunables have been renamed for consistency
with other variables:
kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered
kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered
20120628:
The sort utility has been replaced with BSD sort. For now, GNU sort
is also available as "gnusort" or the default can be set back to
GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be
installed as "bsdsort".
20120611:
A new version of ZFS (pool version 5000) has been merged to -HEAD.
Starting with this version the old system of ZFS pool versioning
is superseded by "feature flags". This concept enables forward
compatibility against certain future changes in functionality of ZFS
pools. The first read-only compatible "feature flag" for ZFS pools
is named "com.delphix:async_destroy". For more information
read the new zpool-features(5) manual page.
Please refer to the "ZFS notes" section of this file for information
on upgrading boot ZFS pools.
20120417:
The malloc(3) implementation embedded in libc now uses sources imported
as contrib/jemalloc. The most disruptive API change is to
/etc/malloc.conf. If your system has an old-style /etc/malloc.conf,
delete it prior to installworld, and optionally re-create it using the
new format after rebooting. See malloc.conf(5) for details
(specifically the TUNING section and the "opt.*" entries in the MALLCTL
NAMESPACE section).
20120328:
Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb
is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is
now spelled mips. This is to aid compatibility with third-party
software that expects this naming scheme in uname(3). Little-endian
settings are unchanged. If you are updating a big-endian mips64 machine
from before this change, you may need to set MACHINE_ARCH=mips64 in
your environment before the new build system will recognize your machine.
20120306:
Disable by default the option VFS_ALLOW_NONMPSAFE for all supported
platforms.
20120229:
Now unix domain sockets behave "as expected" on nullfs(5). Previously
nullfs(5) did not pass through all behaviours to the underlying layer,
as a result if we bound to a socket on the lower layer we could connect
only to the lower path; if we bound to the upper layer we could connect
only to the upper path. The new behavior is one can connect to both the
lower and the upper paths regardless what layer path one binds to.
20120211:
The getifaddrs upgrade path broken with 20111215 has been restored.
If you have upgraded in between 20111215 and 20120209 you need to
recompile libc again with your kernel. You still need to recompile
world to be able to configure CARP but this restriction already
comes from 20111215.
20120114:
The set_rcvar() function has been removed from /etc/rc.subr. All
base and ports rc.d scripts have been updated, so if you have a
port installed with a script in /usr/local/etc/rc.d you can either
hand-edit the rcvar= line, or reinstall the port.
An easy way to handle the mass-update of /etc/rc.d:
rm /etc/rc.d/* && mergemaster -i
20120109:
panic(9) now stops other CPUs in the SMP systems, disables interrupts
on the current CPU and prevents other threads from running.
This behavior can be reverted using the kern.stop_scheduler_on_panic
tunable/sysctl.
The new behavior can be incompatible with kern.sync_on_panic.
20111215:
The carp(4) facility has been changed significantly. Configuration
of the CARP protocol via ifconfig(8) has changed, as well as format
of CARP events submitted to devd(8) has changed. See manual pages
for more information. The arpbalance feature of carp(4) is currently
not supported anymore.
Size of struct in_aliasreq, struct in6_aliasreq has changed. User
utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8),
need to be recompiled.
20111122:
The acpi_wmi(4) status device /dev/wmistat has been renamed to
/dev/wmistat0.
20111108:
The option VFS_ALLOW_NONMPSAFE option has been added in order to
explicitely support non-MPSAFE filesystems.
It is on by default for all supported platform at this present
time.
20111101:
The broken amd(4) driver has been replaced with esp(4) in the amd64,
i386 and pc98 GENERIC kernel configuration files.
20110930:
sysinstall has been removed
20110923:
The stable/9 branch created in subversion. This corresponds to the
RELENG_9 branch in CVS.
20110913:
This commit modifies vfs_register() so that it uses a hash
calculation to set vfc_typenum, which is enabled by default.
The first time a system is booted after this change, the
vfc_typenum values will change for all file systems. The
main effect of this is a change to the NFS server file handles
for file systems that use vfc_typenum in their fsid, such as ZFS.
It will, however, prevent vfc_typenum from changing when file
systems are loaded in a different order for subsequent reboots.
To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf
until you are ready to remount all NFS clients after a reboot.
20110828:
Bump the shared library version numbers for libraries that
do not use symbol versioning, have changed the ABI compared
to stable/8 and which shared library version was not bumped.
Done as part of 9.0-RELEASE cycle.
20110815:
During the merge of Capsicum features, the fget(9) KPI was modified.
This may require the rebuilding of out-of-tree device drivers --
issues have been reported specifically with the nVidia device driver.
__FreeBSD_version is bumped to 900041.
Also, there is a period between 20110811 and 20110814 where the
special devices /dev/{stdin,stdout,stderr} did not work correctly.
Building world from a kernel during that window may not work.
20110628:
The packet filter (pf) code has been updated to OpenBSD 4.5.
You need to update userland tools to be in sync with kernel.
This update breaks backward compatibility with earlier pfsync(4)
versions. Care must be taken when updating redundant firewall setups.
20110608:
The following sysctls and tunables are retired on x86 platforms:
machdep.hlt_cpus
machdep.hlt_logical_cpus
The following sysctl is retired:
machdep.hyperthreading_allowed
The sysctls were supposed to provide a way to dynamically offline and
online selected CPUs on x86 platforms, but the implementation has not
been reliable especially with SCHED_ULE scheduler.
machdep.hyperthreading_allowed tunable is still available to ignore
hyperthreading CPUs at OS level.
Individual CPUs can be disabled using hint.lapic.X.disabled tunable,
where X is an APIC ID of a CPU. Be advised, though, that disabling
CPUs in non-uniform fashion will result in non-uniform topology and
may lead to sub-optimal system performance with SCHED_ULE, which is
a default scheduler.
20110607:
cpumask_t type is retired and cpuset_t is used in order to describe
a mask of CPUs.
20110531:
Changes to ifconfig(8) for dynamic address family detection mandate
that you are running a kernel of 20110525 or later. Make sure to
follow the update procedure to boot a new kernel before installing
world.
20110513:
Support for sun4v architecture is officially dropped
20110503:
Several KPI breaking changes have been committed to the mii(4) layer,
the PHY drivers and consequently some Ethernet drivers using mii(4).
This means that miibus.ko and the modules of the affected Ethernet
drivers need to be recompiled.
Note to kernel developers: Given that the OUI bit reversion problem
was fixed as part of these changes all mii(4) commits related to OUIs,
i.e. to sys/dev/mii/miidevs, PHY driver probing and vendor specific
handling, no longer can be merged verbatim to stable/8 and previous
branches.
20110430:
Users of the Atheros AR71xx SoC code now need to add 'device ar71xx_pci'
into their kernel configurations along with 'device pci'.
20110427:
The default NFS client is now the new NFS client, so fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, it is recommended that the mount(8) and mount_nfs(8)
commands be rebuilt from sources and that a link to mount_nfs called
mount_oldnfs be created. The new client is compiled into the
kernel with "options NFSCL" and this is needed for diskless root
file systems. The GENERIC kernel configs have been changed to use
NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER.
To use the regular/old client, you can "mount -t oldnfs ...". For
a diskless root file system, you must also include a line like:
vfs.root.mountfrom="oldnfs:"
in the boot/loader.conf on the root fs on the NFS server to make
a diskless root fs use the old client.
20110424:
The GENERIC kernels for all architectures now default to the new
CAM-based ATA stack. It means that all legacy ATA drivers were
removed and replaced by respective CAM drivers. If you are using
ATA device names in /etc/fstab or other places, make sure to update
them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY,
where 'Y's are the sequential numbers starting from zero for each type
in order of detection, unless configured otherwise with tunables,
see cam(4)). There will be symbolic links created in /dev/ to map
old adX devices to the respective adaY. They should provide basic
compatibility for file systems mounting in most cases, but they do
not support old user-level APIs and do not have respective providers
in GEOM. Consider using updated management tools with new device names.
It is possible to load devices ahci, ata, siis and mvs as modules,
but option ATA_CAM should remain in kernel configuration to make ata
module work as CAM driver supporting legacy ATA controllers. Device ata
still can be used in modular fashion (atacore + ...). Modules atadisk
and atapi* are not used and won't affect operation in ATA_CAM mode.
Note that to use CAM-based ATA kernel should include CAM devices
scbus, pass, da (or explicitly ada), cd and optionally others. All of
them are parts of the cam module.
ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.
No kernel config options or code have been removed, so if a problem
arises, please report it and optionally revert to the old ATA stack.
In order to do it you can remove from the kernel config:
options ATA_CAM
device ahci
device mvs
device siis
, and instead add back:
device atadisk # ATA disk drives
device ataraid # ATA RAID drives
device atapicd # ATAPI CDROM drives
device atapifd # ATAPI floppy drives
device atapist # ATAPI tape drives
20110423:
The default NFS server has been changed to the new server, which
was referred to as the experimental server. If you need to switch
back to the old NFS server, you must now put the "-o" option on
both the mountd and nfsd commands. This can be done using the
mountd_flags and nfs_server_flags rc.conf variables until an
update to the rc scripts is committed, which is coming soon.
20110418:
The GNU Objective-C runtime library (libobjc), and other Objective-C
related components have been removed from the base system. If you
require an Objective-C library, please use one of the available ports.
20110331:
ath(4) has been split into bus- and device- modules. if_ath contains
the HAL, the TX rate control and the network device code. if_ath_pci
contains the PCI bus glue. For Atheros MIPS embedded systems, if_ath_ahb
contains the AHB glue. Users need to load both if_ath_pci and if_ath
in order to use ath on everything else.
TO REPEAT: if_ath_ahb is not needed for normal users. Normal users only
need to load if_ath and if_ath_pci for ath(4) operation.
20110314:
As part of the replacement of sysinstall, the process of building
release media has changed significantly. For details, please re-read
release(7), which has been updated to reflect the new build process.
20110218:
GNU binutils 2.17.50 (as of 2007-07-03) has been merged to -HEAD. This
is the last available version under GPLv2. It brings a number of new
features, such as support for newer x86 CPU's (with SSE-3, SSSE-3, SSE
4.1 and SSE 4.2), better support for powerpc64, a number of new
directives, and lots of other small improvements. See the ChangeLog
file in contrib/binutils for the full details.
20110218:
IPsec's HMAC_SHA256-512 support has been fixed to be RFC4868
compliant, and will now use half of hash for authentication.
This will break interoperability with all stacks (including all
actual FreeBSD versions) who implement
draft-ietf-ipsec-ciph-sha-256-00 (they use 96 bits of hash for
authentication).
The only workaround with such peers is to use another HMAC
algorithm for IPsec ("phase 2") authentication.
20110207:
Remove the uio_yield prototype and symbol. This function has
been misnamed since it was introduced and should not be
globally exposed with this name. The equivalent functionality
is now available using kern_yield(curthread->td_user_pri).
The function remains undocumented.
20110112:
A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers,
symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking
for scalar sysctls is defined but disabled. Code that needs
UQUAD to pass the type checking that must compile on older
systems where the define is not present can check against
__FreeBSD_version >= 900030.
The system dialog(1) has been replaced with a new version previously
in ports as devel/cdialog. dialog(1) is mostly command-line compatible
with the previous version, but the libdialog associated with it has
a largely incompatible API. As such, the original version of libdialog
will be kept temporarily as libodialog, until its base system consumers
are replaced or updated. Bump __FreeBSD_version to 900030.
20110103:
If you are trying to run make universe on a -stable system, and you get
the following warning:
"Makefile", line 356: "Target architecture for i386/conf/GENERIC
unknown. config(8) likely too old."
or something similar to it, then you must upgrade your -stable system
to 8.2-Release or newer (really, any time after r210146 7/15/2010 in
stable/8) or build the config from the latest stable/8 branch and
install it on your system.
Prior to this date, building a current universe on 8-stable system from
between 7/15/2010 and 1/2/2011 would result in a weird shell parsing
error in the first kernel build phase. A new config on those old
systems will fix that problem for older versions of -current.

The TCP stack has been modified to allow Khelp modules to interact with
it via helper hook points and store per-connection data in the TCP
control block. Bump __FreeBSD_version to 900029. User space tools that
rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to
be recompiled.
20101114:
Generic IEEE 802.3 annex 31B full duplex flow control support has been
added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along
with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted
to take advantage of it instead of using custom implementations. This
means that these drivers now no longer unconditionally advertise
support for flow control but only do so if flow control is a selected
media option. This was implemented in the generic support that way in
order to allow flow control to be switched on and off via ifconfig(8)
with the PHY specific default to typically off in order to protect
from unwanted effects. Consequently, if you used flow control with
one of the above mentioned drivers you now need to explicitly enable
it, for example via:
ifconfig bge0 media auto mediaopt flowcontrol
Along with the above mentioned changes generic support for setting
1000baseT master mode also has been added and brgphy(4), ciphy(4),
e1000phy(4) as well as ip1000phy(4) have been converted to take
advantage of it. This means that these drivers now no longer take the
link0 parameter for selecting master mode but the master media option
has to be used instead, for example like in the following:
ifconfig bge0 media 1000baseT mediaopt full-duplex,master
Selection of master mode now is also available with all other PHY
drivers supporting 1000baseT.
20101111:
The TCP stack has received a significant update to add support for
modularised congestion control and generally improve the clarity of
congestion control decisions. Bump __FreeBSD_version to 900025. User
space tools that rely on the size of struct tcpcb in tcp_var.h (e.g.
sockstat) need to be recompiled.
20101002:
The man(1) utility has been replaced by a new version that no longer
uses /etc/manpath.config. Please consult man.conf(5) for how to
migrate local entries to the new format.
20100928:
The copyright strings printed by login(1) and sshd(8) at the time of a
new connection have been removed to follow other operating systems and
upstream sshd.
20100915:
A workaround for a fixed ld bug has been removed in kernel code,
so make sure that your system ld is built from sources after
revision 210245 from 2010-07-19 (r211583 if building head kernel
on stable/8, r211584 for stable/7; both from 2010-08-21).
A symptom of incorrect ld version is different addresses for
set_pcpu section and __start_set_pcpu symbol in kernel and/or modules.
20100913:
The $ipv6_prefer variable in rc.conf(5) has been split into
$ip6addrctl_policy and $ipv6_activate_all_interfaces.
The $ip6addrctl_policy is a variable to choose a pre-defined
address selection policy set by ip6addrctl(8). A value
"ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The
default is "AUTO".
The $ipv6_activate_all_interfaces specifies whether IFDISABLED
flag (see an entry of 20090926) is set on an interface with no
corresponding $ifconfig_IF_ipv6 line. The default is "NO" for
security reason. If you want IPv6 link-local address on all
interfaces by default, set this to "YES".
The old ipv6_prefer="YES" is equivalent to
ipv6_activate_all_interfaces="YES" and
ip6addrctl_policy="ipv6_prefer".
20100913:
DTrace has grown support for userland tracing. Due to this, DTrace is
now i386 and amd64 only.
dtruss(1) is now installed by default on those systems and a new
kernel module is needed for userland tracing: fasttrap.
No changes to your kernel config file are necessary to enable
userland tracing, but you might consider adding 'STRIP=' and
'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want
to have informative userland stack traces in DTrace (ustack).
20100725:
The acpi_aiboost(4) driver has been removed in favor of the new
aibs(4) driver. You should update your kernel configuration file.
20100722:
BSD grep has been imported to the base system and it is built by
default. It is completely BSD licensed, highly GNU-compatible, uses
less memory than its GNU counterpart and has a small codebase.
However, it is slower than its GNU counterpart, which is mostly
noticeable for larger searches, for smaller ones it is measurable
but not significant. The reason is complex, the most important factor
is that we lack a modern and efficient regex library and GNU
overcomes this by optimizing the searches internally. Future work
on improving the regex performance is planned, for the meantime,
users that need better performance, can build GNU grep instead by
setting the WITH_GNU_GREP knob.
20100713:
Due to the import of powerpc64 support, all existing powerpc kernel
configuration files must be updated with a machine directive like this:
machine powerpc powerpc
In addition, an updated config(8) is required to build powerpc kernels
after this change.
20100713:
A new version of ZFS (version 15) has been merged to -HEAD.
This version uses a python library for the following subcommands:
zfs allow, zfs unallow, zfs groupspace, zfs userspace.
For full functionality of these commands the following port must
be installed: sysutils/py-zfs
20100429:
'vm_page's are now hashed by physical address to an array of mutexes.
Currently this is only used to serialize access to hold_count. Over
time the page queue mutex will be peeled away. This changes the size
of pmap on every architecture. And requires all callers of vm_page_hold
and vm_page_unhold to be updated.
20100402:
WITH_CTF can now be specified in src.conf (not recommended, there
are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").
When WITH_CTF was specified there before this was silently ignored,
so make sure that WITH_CTF is not used in places which could lead
to unwanted behavior.
20100311:
The kernel option COMPAT_IA32 has been replaced with COMPAT_FREEBSD32
to allow 32-bit compatibility on non-x86 platforms. All kernel
configurations on amd64 and ia64 platforms using these options must
be modified accordingly.
20100113:
The utmp user accounting database has been replaced with utmpx,
the user accounting interface standardized by POSIX.
Unfortunately the semantics of utmp and utmpx don't match,
making it practically impossible to support both interfaces.
The user accounting database is used by tools like finger(1),
last(1), talk(1), w(1) and ac(8).
All applications in the base system use utmpx. This means only
local binaries (e.g. from the ports tree) may still use these
utmp database files. These applications must be rebuilt to make
use of utmpx.
After the system has been upgraded, it is safe to remove the old
log files (/var/run/utmp, /var/log/lastlog and /var/log/wtmp*),
assuming their contents is of no importance anymore. Old wtmp
databases can only be used by last(1) and ac(8) after they have
been converted to the new format using wtmpcvt(1).
20100108:
Introduce the kernel thread "deadlock resolver" (which can be enabled
via the DEADLKRES option, see NOTES for more details) and the
sleepq_type() function for sleepqueues.
20091202:
The rc.firewall and rc.firewall6 were unified, and
rc.firewall6 and rc.d/ip6fw were removed.
According to the removal of rc.d/ip6fw, ipv6_firewall_* rc
variables are obsoleted. Instead, the following new rc
variables are added to rc.d/ipfw:
firewall_client_net_ipv6, firewall_simple_iif_ipv6,
firewall_simple_inet_ipv6, firewall_simple_oif_ipv6,
firewall_simple_onet_ipv6, firewall_trusted_ipv6
The meanings correspond to the relevant IPv4 variables.
20091125:
8.0-RELEASE.
