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 and WITH_GCC to bootstrap to
the tip of head, and then rebuild without this option. The bootstrap process
from older version of current across the gcc/clang cutover is a bit fragile.
NOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW:
FreeBSD 12.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".)
****************************** SPECIAL WARNING: ******************************
Due to a bug in some versions of clang that's very hard to workaround in
the upgrade process, to upgrade to -current you must first upgrade
either stable/9 after r286035 or stable/10 after r286033 (including
10.3-RELEASE) or current after r286007 (including stable/11 and
11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so
you'll need to take the unusual step of upgrading to the tip of the
stable branch before moving to 11 or -current via a source upgrade.
stable/11 and 11.0-RELEASE have working newer compiler. This differs
from the historical situation where one could upgrade from anywhere on
the last couple of stable branches, so be careful.
If you're running a hybrid system on 9.x or 10.x with an updated clang
compiler or are using an supported external toolchain, the build system
will allow the upgrade. Otherwise it will print a reminder.
****************************** SPECIAL WARNING: ******************************
20170315:
The syntax of ipfw(8) named states was changed to avoid ambiguity.
If you have used named states in the firewall rules, you need to modify
them after installworld and before rebooting. Now named states must
be prefixed with colon.
20170311:
The old drm (sys/dev/drm/) drivers for i915 and radeon have been
removed as the userland we provide cannot use them. The KMS version
(sys/dev/drm2) support the same hardware.
20170311:
GNU diff has been replaced by a BSD licensed diff. Some features of GNU
diff has not been implemented, if those are needed a newer version of
GNU diff is available via the diffutils package under the gdiff name.
20170302:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20170221:
The code that provides support for ZFS .zfs/ directory functionality
has been reimplemented. It's not possible now to create a snapshot
by mkdir under .zfs/snapshot/. That should be the only user visible
change.
20170216:
EISA bus support has been removed. The WITH_EISA option is no longer
valid.
20170215:
MCA bus support has been removed.
20170127:
The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
20170112:
The EM_MULTIQUEUE kernel configuration option is deprecated now that
the em(4) driver conforms to iflib specifications.
20170109:
The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
IFLIB. If you have a custom kernel configuration that excludes em(4)
but you use igb(4), you need to re-add em(4) to your custom configuration.
20161217:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20161124:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20161119:
The layout of the pmap structure has changed for powerpc to put the pmap
statistics at the front for all CPU variations. libkvm(3) and all tools
that link against it need to be recompiled.
20161030:
isl(4) and cyapa(4) drivers now require a new driver,
chromebook_platform(4), to work properly on Chromebook-class hardware.
On other types of hardware the drivers may need to be configured using
device hints. Please see the corresponding manual pages for details.
20161017:
The urtwn(4) driver was merged into rtwn(4) and now consists of
rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
parts.
Also, firmware for RTL8188CE was renamed due to possible name
conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
20161015:
GNU rcs has been removed from base. It is available as packages:
- rcs: Latest GPLv3 GNU rcs version.
- rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
removed from base.
20161008:
Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
modules now requires that the kernel configuration contain the
TCP_HHOOK option. (This option is included in the GENERIC kernel.)
20161003:
The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
20160924:
Relocatable object files with the extension of .So have been renamed
to use an extension of .pico instead. The purpose of this change is
to avoid a name clash with shared libraries on case-insensitive file
systems. On those file systems, foo.So is the same file as foo.so.
20160918:
GNU rcs has been turned off by default. It can (temporarily) be built
again by adding WITH_RCS knob in src.conf.
Otherwise, GNU rcs is available from packages:
- rcs: Latest GPLv3 GNU rcs version.
- rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
20160918:
The backup_uses_rcs functionality has been removed from rc.subr.
20160908:
The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
two separate components, QUEUE_MACRO_DEBUG_TRACE and
QUEUE_MACRO_DEBUG_TRASH. Define both for the original
QUEUE_MACRO_DEBUG behavior.
20160824:
r304787 changed some ioctl interfaces between the iSCSI userspace
programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
rebuilt to work with new kernels. __FreeBSD_version has been bumped
to 1200005.
20160818:
The UDP receive code has been updated to only treat incoming UDP
packets that were addressed to an L2 broadcast address as L3
broadcast packets. It is not expected that this will affect any
standards-conforming UDP application. The new behaviour can be
disabled by setting the sysctl net.inet.udp.require_l2_bcast to
0.
20160818:
Remove the openbsd_poll system call.
__FreeBSD_version has been bumped because of this.
20160622:
The libc stub for the pipe(2) system call has been replaced with
a wrapper that calls the pipe2(2) system call and the pipe(2)
system call is now only implemented by the kernels that include
"options COMPAT_FREEBSD10" in their config file (this is the
default). Users should ensure that this option is enabled in
their kernel or upgrade userspace to r302092 before upgrading their
kernel.
20160527:
CAM will now strip leading spaces from SCSI disks' serial numbers.
This will affect users who create UFS filesystems on SCSI disks using
those disk's diskid device nodes. For example, if /etc/fstab
previously contained a line like
"/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
transforms like gmirror may also be affected. ZFS users should
generally be fine.
20160523:
The bitstring(3) API has been updated with new functionality and
improved performance. But it is binary-incompatible with the old API.
Objects built with the new headers may not be linked against objects
built with the old headers.
20160520:
The brk and sbrk functions have been removed from libc on arm64.
Binutils from ports has been updated to not link to these
functions and should be updated to the latest version before
installing a new libc.
20160517:
The armv6 port now defaults to hard float ABI. Limited support
for running both hardfloat and soft float on the same system
is available using the libraries installed with -DWITH_LIBSOFT.
This has only been tested as an upgrade path for installworld
and packages may fail or need manual intervention to run. New
packages will be needed.
To update an existing self-hosted armv6hf system, you must add
TARGET_ARCH=armv6 on the make command line for both the build
and the install steps.
20160510:
Kernel modules compiled outside of a kernel build now default to
installing to /boot/modules instead of /boot/kernel. Many kernel
modules built this way (such as those in ports) already overrode
KMODDIR explicitly to install into /boot/modules. However,
manually building and installing a module from /sys/modules will
now install to /boot/modules instead of /boot/kernel.
20160414:
The CAM I/O scheduler has been committed to the kernel. There should be
no user visible impact. This does enable NCQ Trim on ada SSDs. While the
list of known rogues that claim support for this but actually corrupt
data is believed to be complete, be on the lookout for data
corruption. The known rogue list is believed to be complete:
o Crucial MX100, M550 drives with MU01 firmware.
o Micron M510 and M550 drives with MU01 firmware.
o Micron M500 prior to MU07 firmware
o Samsung 830, 840, and 850 all firmwares
o FCCT M500 all firmwares
Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
with working NCQ TRIM. For Micron branded drives, see your sales rep for
updated firmware. Black listed drives will work correctly because these
drives work correctly so long as no NCQ TRIMs are sent to them. Given
this list is the same as found in Linux, it's believed there are no
other rogues in the market place. All other models from the above
vendors work.
To be safe, if you are at all concerned, you can quirk each of your
drives to prevent NCQ from being sent by setting:
kern.cam.ada.X.quirks="0x2"
in loader.conf. If the drive requires the 4k sector quirk, set the
quirks entry to 0x3.
20160330:
The FAST_DEPEND build option has been removed and its functionality is
now the one true way. The old mkdep(1) style of 'make depend' has
been removed. See 20160311 for further details.
20160317:
Resource range types have grown from unsigned long to uintmax_t. All
drivers, and anything using libdevinfo, need to be recompiled.
20160311:
WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
builds. It no longer runs mkdep(1) during 'make depend', and the
'make depend' stage can safely be skipped now as it is auto ran
when building 'make all' and will generate all SRCS and DPSRCS before
building anything else. Dependencies are gathered at compile time with
-MF flags kept in separate .depend files per object file. Users should
run 'make cleandepend' once if using -DNO_CLEAN to clean out older
stale .depend files.
20160306:
On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
kernel modules. Therefore, if you load any kernel modules at boot time,
please install the boot loaders after you install the kernel, but before
rebooting, e.g.:
make buildworld
make kernel KERNCONF=YOUR_KERNEL_HERE
make -C sys/boot install
<reboot in single user>
Then follow the usual steps, described in the General Notes section,
below.
20160305:
Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
see the 20141231 entry below for information about prerequisites and
upgrading, if you are not already using clang 3.5.0 or higher.
20160301:
The AIO subsystem is now a standard part of the kernel. The
VFS_AIO kernel option and aio.ko kernel module have been removed.
Due to stability concerns, asynchronous I/O requests are only
permitted on sockets and raw disks by default. To enable
asynchronous I/O requests on all file types, set the
vfs.aio.enable_unsafe sysctl to a non-zero value.
20160226:
The ELF object manipulation tool objcopy is now provided by the
ELF Tool Chain project rather than by GNU binutils. It should be a
drop-in replacement, with the addition of arm64 support. The
(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
to obtain the GNU version if necessary.
20160129:
Building ZFS pools on top of zvols is prohibited by default. That
feature has never worked safely; it's always been prone to deadlocks.
Using a zvol as the backing store for a VM guest's virtual disk will
still work, even if the guest is using ZFS. Legacy behavior can be
restored by setting vfs.zfs.vol.recursive=1.
20160119:
The NONE and HPN patches has been removed from OpenSSH. They are
still available in the security/openssh-portable port.
20160113:
With the addition of ypldap(8), a new _ypldap user is now required
during installworld. "mergemaster -p" can be used to add the user
prior to installworld, as documented in the handbook.
20151216:
The tftp loader (pxeboot) now uses the option root-path directive. As a
consequence it no longer looks for a pxeboot.4th file on the tftp
server. Instead it uses the regular /boot infrastructure as with the
other loaders.
20151211:
The code to start recording plug and play data into the modules has
been committed. While the old tools will properly build a new kernel,
a number of warnings about "unknown metadata record 4" will be produced
for an older kldxref. To avoid such warnings, make sure to rebuild
the kernel toolchain (or world). Make sure that you have r292078 or
later when trying to build 292077 or later before rebuilding.
20151207:
Debug data files are now built by default with 'make buildworld' and
installed with 'make installworld'. This facilitates debugging but
requires more disk space both during the build and for the installed
world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
in src.conf(5).
20151130:
r291527 changed the internal interface between the nfsd.ko and
nfscommon.ko modules. As such, they must both be upgraded to-gether.
__FreeBSD_version has been bumped because of this.
20151108:
Add support for unicode collation strings leads to a change of
order of files listed by ls(1) for example. To get back to the old
behaviour, set LC_COLLATE environment variable to "C".
Databases administrators will need to reindex their databases given
collation results will be different.
Due to a bug in install(1) it is recommended to remove the ancient
locales before running make installworld.
rm -rf /usr/share/locale/*
20151030:
The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
libcrypto.so.7 or libssl.so.7 must be recompiled.
20151020:
Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
Kernel modules isp_2400_multi and isp_2500_multi were removed and
should be replaced with isp_2400 and isp_2500 modules respectively.
20151017:
The build previously allowed using 'make -n' to not recurse into
sub-directories while showing what commands would be executed, and
'make -n -n' to recursively show commands. Now 'make -n' will recurse
and 'make -N' will not.
20151012:
If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
and etcupdate will now use this file. A custom sendmail.cf is now
updated via this mechanism rather than via installworld. If you had
excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
want to remove the exclusion or change it to "always install".
/etc/mail/sendmail.cf is now managed the same way regardless of
whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
20151011:
Compatibility shims for legacy ATA device names have been removed.
It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
environment variables, /dev/ad* and /dev/ar* symbolic links.
20151006:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20150924:
Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
and renamed from .symbols to .debug. This reduces the size requirements
on the boot partition or file system and provides consistency with
userland debug files.
When using the supported kernel installation method the
/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
as is done with /boot/kernel.
Developers wishing to maintain the historical behavior of installing
debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
20150827:
The wireless drivers had undergone changes that remove the 'parent
interface' from the ifconfig -l output. The rc.d network scripts
used to check presence of a parent interface in the list, so old
scripts would fail to start wireless networking. Thus, etcupdate(3)
or mergemaster(8) run is required after kernel update, to update your
rc.d scripts in /etc.
20150827:
pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
These configurations are now automatically interpreted as
'scrub fragment reassemble'.
20150817:
Kernel-loadable modules for the random(4) device are back. To use
them, the kernel must have
device random
options RANDOM_LOADABLE
kldload(8) can then be used to load random_fortuna.ko
or random_yarrow.ko. Please note that due to the indirect
function calls that the loadable modules need to provide,
the build-in variants will be slightly more efficient.
The random(4) kernel option RANDOM_DUMMY has been retired due to
unpopularity. It was not all that useful anyway.
20150813:
The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
Control over building the ELF Tool Chain tools is now provided by
the WITHOUT_TOOLCHAIN knob.
20150810:
The polarity of Pulse Per Second (PPS) capture events with the
uart(4) driver has been corrected. Prior to this change the PPS
"assert" event corresponded to the trailing edge of a positive PPS
pulse and the "clear" event was the leading edge of the next pulse.
As the width of a PPS pulse in a typical GPS receiver is on the
order of 1 millisecond, most users will not notice any significant
difference with this change.
Anyone who has compensated for the historical polarity reversal by
configuring a negative offset equal to the pulse width will need to
remove that workaround.
20150809:
The default group assigned to /dev/dri entries has been changed
from 'wheel' to 'video' with the id of '44'. If you want to have
access to the dri devices please add yourself to the video group
with:
# pw groupmod video -m $USER
20150806:
The menu.rc and loader.rc files will now be replaced during
upgrades. Please migrate local changes to menu.rc.local and
loader.rc.local instead.
20150805:
GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
strings and strip have been removed. The src.conf(5) knob
WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
20150728:
As ZFS requires more kernel stack pages than is the default on some
architectures e.g. i386, it now warns if KSTACK_PAGES is less than
ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
Please consider using 'options KSTACK_PAGES=X' where X is greater
than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
20150706:
sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
default, i.e., they will not contain "::". For example, instead
of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
to have a more specific match, such as different map entries for
IPv6:0:0 vs IPv6:0. This change requires that configuration
data (including maps, files, classes, custom ruleset, etc.) must
use the same format, so make certain such configuration data is
upgrading. As a very simple check search for patterns like
'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
the cf option UseCompressedIPv6Addresses.
20150630:
The default kernel entropy-processing algorithm is now
Fortuna, replacing Yarrow.
Assuming you have 'device random' in your kernel config
file, the configurations allow a kernel option to override
this default. You may choose *ONE* of:
options RANDOM_YARROW # Legacy /dev/random algorithm.
options RANDOM_DUMMY # Blocking-only driver.
If you have neither, you get Fortuna. For most people,
read no further, Fortuna will give a /dev/random that works
like it always used to, and the difference will be irrelevant.
If you remove 'device random', you get *NO* kernel-processed
entropy at all. This may be acceptable to folks building
embedded systems, but has complications. Carry on reading,
and it is assumed you know what you need.
*PLEASE* read random(4) and random(9) if you are in the
habit of tweaking kernel configs, and/or if you are a member
of the embedded community, wanting specific and not-usual
behaviour from your security subsystems.
NOTE!! If you use RANDOM_DUMMY and/or have no 'device
random', you will NOT have a functioning /dev/random, and
many cryptographic features will not work, including SSH.
You may also find strange behaviour from the random(3) set
of library functions, in particular sranddev(3), srandomdev(3)
and arc4random(3). The reason for this is that the KERN_ARND
sysctl only returns entropy if it thinks it has some to
share, and with RANDOM_DUMMY or no 'device random' this
will never happen.
20150623:
An additional fix for the issue described in the 20150614 sendmail
entry below has been been committed in revision 284717.
20150616:
FreeBSD's old make (fmake) has been removed from the system. It is
available as the devel/fmake port or via pkg install fmake.
20150615:
The fix for the issue described in the 20150614 sendmail entry
below has been been committed in revision 284436. The work
around described in that entry is no longer needed unless the
default setting is overridden by a confDH_PARAMETERS configuration
setting of '5' or pointing to a 512 bit DH parameter file.
20150614:
ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
and devel/kyua to version 0.20+ and adjust any calling code to work
with Kyuafile and kyua.
20150614:
The import of openssl to address the FreeBSD-SA-15:10.openssl
security advisory includes a change which rejects handshakes
with DH parameters below 768 bits. sendmail releases prior
to 8.15.2 (not yet released), defaulted to a 512 bit
DH parameter setting for client connections. To work around
this interoperability, sendmail can be configured to use a
2048 bit DH parameter by:
1. Edit /etc/mail/`hostname`.mc
2. If a setting for confDH_PARAMETERS does not exist or
exists and is set to a string beginning with '5',
replace it with '2'.
3. If a setting for confDH_PARAMETERS exists and is set to
a file path, create a new file with:
openssl dhparam -out /path/to/file 2048
4. Rebuild the .cf file:
cd /etc/mail/; make; make install
5. Restart sendmail:
cd /etc/mail/; make restart
A sendmail patch is coming, at which time this file will be
updated.
20150604:
Generation of legacy formatted entries have been disabled by default
in pwd_mkdb(8), as all base system consumers of the legacy formatted
entries were converted to use the new format by default when the new,
machine independent format have been added and supported since FreeBSD
5.x.
Please see the pwd_mkdb(8) manual page for further details.
20150525:
Clang and llvm have been upgraded to 3.6.1 release. Please see the
20141231 entry below for information about prerequisites and upgrading,
if you are not already using 3.5.0 or higher.
20150521:
TI platform code switched to using vendor DTS files and this update
may break existing systems running on Beaglebone, Beaglebone Black,
and Pandaboard:
- dtb files should be regenerated/reinstalled. Filenames are the
same but content is different now
- GPIO addressing was changed, now each GPIO bank (32 pins per bank)
has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
addressing scheme is now pin 25 on /dev/gpioc3.
- Pandaboard: /etc/ttys should be updated, serial console device is
now /dev/ttyu2, not /dev/ttyu0
20150501:
soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
If you need the GNU extension from groff soelim(1), install groff
from package: pkg install groff, or via ports: textproc/groff.
20150423:
chmod, chflags, chown and chgrp now affect symlinks in -R mode as
defined in symlink(7); previously symlinks were silently ignored.
20150415:
The const qualifier has been removed from iconv(3) to comply with
POSIX. The ports tree is aware of this from r384038 onwards.
20150416:
Libraries specified by LIBADD in Makefiles must have a corresponding
DPADD_<lib> variable to ensure correct dependencies. This is now
enforced in src.libnames.mk.
20150324:
From legacy ata(4) driver was removed support for SATA controllers
supported by more functional drivers ahci(4), siis(4) and mvs(4).
Kernel modules ataahci and ataadaptec were removed completely,
replaced by ahci and mvs modules respectively.
20150315:
Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
the 20141231 entry below for information about prerequisites and
upgrading, if you are not already using 3.5.0 or higher.
20150307:
The 32-bit PowerPC kernel has been changed to a position-independent
executable. This can only be booted with a version of loader(8)
newer than January 31, 2015, so make sure to update both world and
kernel before rebooting.
20150217:
If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
but before r278950, the RNG was not seeded properly. Immediately
upgrade the kernel to r278950 or later and regenerate any keys (e.g.
ssh keys or openssl keys) that were generated w/ a kernel from that
range. This does not affect programs that directly used /dev/random
or /dev/urandom. All userland uses of arc4random(3) are affected.
20150210:
The autofs(4) ABI was changed in order to restore binary compatibility
with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
with the new kernel.
20150131:
The powerpc64 kernel has been changed to a position-independent
executable. This can only be booted with a new version of loader(8),
so make sure to update both world and kernel before rebooting.
20150118:
Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
only release, no new features have been added. Please see the 20141231
entry below for information about prerequisites and upgrading, if you
are not already using 3.5.0.
20150107:
ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
taken from the ELF Tool Chain project rather than GNU binutils. They
should be drop-in replacements, with the addition of arm64 support.
The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
binutils tools, if necessary. See 20150805 for updated information.
20150105:
The default Unbound configuration now enables remote control
using a local socket. Users who have already enabled the
local_unbound service should regenerate their configuration
by running "service local_unbound setup" as root.
20150102:
The GNU texinfo and GNU info pages have been removed.
To be able to view GNU info pages please install texinfo from ports.
20141231:
Clang, llvm and lldb have been upgraded to 3.5.0 release.
As of this release, a prerequisite for building clang, llvm and lldb is
a C++11 capable compiler and C++11 standard library. This means that to
be able to successfully build the cross-tools stage of buildworld, with
clang as the bootstrap compiler, your system compiler or cross compiler
should either be clang 3.3 or later, or gcc 4.8 or later, and your
system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
later.
On any standard FreeBSD 10.x or 11.x installation, where clang and
libc++ are on by default (that is, on x86 or arm), this should work out
of the box.
On 9.x installations where clang is enabled by default, e.g. on x86 and
powerpc, libc++ will not be enabled by default, so libc++ should be
built (with clang) and installed first. If both clang and libc++ are
missing, build clang first, then use it to build libc++.
On 8.x and earlier installations, upgrade to 9.x first, and then follow
the instructions for 9.x above.
Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
default, and do not build clang.
Many embedded systems are resource constrained, and will not be able to
build clang in a reasonable time, or in some cases at all. In those
cases, cross building bootable systems on amd64 is a workaround.
This new version of clang introduces a number of new warnings, of which
the following are most likely to appear:
-Wabsolute-value
This warns in two cases, for both C and C++:
* When the code is trying to take the absolute value of an unsigned
quantity, which is effectively a no-op, and almost never what was
intended. The code should be fixed, if at all possible. If you are
sure that the unsigned quantity can be safely cast to signed, without
loss of information or undefined behavior, you can add an explicit
cast, or disable the warning.
* When the code is trying to take an absolute value, but the called
abs() variant is for the wrong type, which can lead to truncation.
If you want to disable the warning instead of fixing the code, please
make sure that truncation will not occur, or it might lead to unwanted
side-effects.
-Wtautological-undefined-compare and
-Wundefined-bool-conversion
These warn when C++ code is trying to compare 'this' against NULL, while
'this' should never be NULL in well-defined C++ code. However, there is
some legacy (pre C++11) code out there, which actively abuses this
feature, which was less strictly defined in previous C++ versions.
Squid and openjdk do this, for example. The warning can be turned off
for C++98 and earlier, but compiling the code in C++11 mode might result
in unexpected behavior; for example, the parts of the program that are
unreachable could be optimized away.
20141222:
The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
kernel sources have been removed. The .h files remain, since some
utilities include them. This will need to be fixed later.
If "mount -t oldnfs ..." is attempted, it will fail.
If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
the utilities will report errors.
20141121:
The handling of LOCAL_LIB_DIRS has been altered to skip addition of
directories to top level SUBDIR variable when their parent
directory is included in LOCAL_DIRS. Users with build systems with
such hierarchies and without SUBDIR entries in the parent
directory Makefiles should add them or add the directories to
LOCAL_DIRS.
20141109:
faith(4) and faithd(8) have been removed from the base system. Faith
has been obsolete for a very long time.
20141104:
vt(4), the new console driver, is enabled by default. It brings
support for Unicode and double-width characters, as well as
support for UEFI and integration with the KMS kernel video
drivers.
You may need to update your console settings in /etc/rc.conf,
most probably the keymap. During boot, /etc/rc.d/syscons will
indicate what you need to do.
vt(4) still has issues and lacks some features compared to
syscons(4). See the wiki for up-to-date information:
https://wiki.freebsd.org/Newcons
If you want to keep using syscons(4), you can do so by adding
the following line to /boot/loader.conf:
kern.vty=sc
20141102:
pjdfstest has been integrated into kyua as an opt-in test suite.
Please see share/doc/pjdfstest/README for more details on how to
execute it.
20141009:
gperf has been removed from the base system for architectures
that use clang. Ports that require gperf will obtain it from the
devel/gperf port.
20140923:
pjdfstest has been moved from tools/regression/pjdfstest to
contrib/pjdfstest .
20140922:
At svn r271982, The default linux compat kernel ABI has been adjusted
to 2.6.18 in support of the linux-c6 compat ports infrastructure
update. If you wish to continue using the linux-f10 compat ports,
add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
encouraged to update their linux-compat packages to linux-c6 during
their next update cycle.
20140729:
The ofwfb driver, used to provide a graphics console on PowerPC when
using vt(4), no longer allows mmap() of all physical memory. This
will prevent Xorg on PowerPC with some ATI graphics cards from
initializing properly unless x11-servers/xorg-server is updated to
1.12.4_8 or newer.
20140723:
The xdev targets have been converted to using TARGET and
TARGET_ARCH instead of XDEV and XDEV_ARCH.
20140719:
The default unbound configuration has been modified to address
issues with reverse lookups on networks that use private
address ranges. If you use the local_unbound service, run
"service local_unbound setup" as root to regenerate your
configuration, then "service local_unbound reload" to load the
new configuration.
20140709:
The GNU texinfo and GNU info pages are not built and installed
anymore, WITH_INFO knob has been added to allow to built and install
them again.
UPDATE: see 20150102 entry on texinfo's removal
20140708:
The GNU readline library is now an INTERNALLIB - that is, it is
statically linked into consumers (GDB and variants) in the base
system, and the shared library is no longer installed. The
devel/readline port is available for third party software that
requires readline.
20140702:
The Itanium architecture (ia64) has been removed from the list of
known architectures. This is the first step in the removal of the
architecture.
20140701:
Commit r268115 has added NFSv4.1 server support, merged from
projects/nfsv4.1-server. Since this includes changes to the
internal interfaces between the NFS related modules, a full
build of the kernel and modules will be necessary.
__FreeBSD_version has been bumped.
20140629:
The WITHOUT_VT_SUPPORT kernel config knob has been renamed
WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
which differs from the behaviour controlled by this knob.)
20140619:
Maximal length of the serial number in CTL was increased from 16 to
64 chars, that breaks ABI. All CTL-related tools, such as ctladm
and ctld, need to be rebuilt to work with a new kernel.
20140606:
The libatf-c and libatf-c++ major versions were downgraded to 0 and
1 respectively to match the upstream numbers. They were out of
sync because, when they were originally added to FreeBSD, the
upstream versions were not respected. These libraries are private
and not yet built by default, so renumbering them should be a
non-issue. However, unclean source trees will yield broken test
programs once the operator executes "make delete-old-libs" after a
"make installworld".
Additionally, the atf-sh binary was made private by moving it into
/usr/libexec/. Already-built shell test programs will keep the
path to the old binary so they will break after "make delete-old"
is run.
If you are using WITH_TESTS=yes (not the default), wipe the object
tree and rebuild from scratch to prevent spurious test failures.
This is only needed once: the misnumbered libraries and misplaced
binaries have been added to OptionalObsoleteFiles.inc so they will
be removed during a clean upgrade.
20140512:
Clang and llvm have been upgraded to 3.4.1 release.
20140508:
We bogusly installed src.opts.mk in /usr/share/mk. This file should
be removed to avoid issues in the future (and has been added to
ObsoleteFiles.inc).
20140505:
/etc/src.conf now affects only builds of the FreeBSD src tree. In the
past, it affected all builds that used the bsd.*.mk files. The old
behavior was a bug, but people may have relied upon it. To get this
behavior back, you can .include /etc/src.conf from /etc/make.conf
(which is still global and isn't changed). This also changes the
behavior of incremental builds inside the tree of individual
directories. Set MAKESYSPATH to ".../share/mk" to do that.
Although this has survived make universe and some upgrade scenarios,
other upgrade scenarios may have broken. At least one form of
temporary breakage was fixed with MAKESYSPATH settings for buildworld
as well... In cases where MAKESYSPATH isn't working with this
setting, you'll need to set it to the full path to your tree.
One side effect of all this cleaning up is that bsd.compiler.mk
is no longer implicitly included by bsd.own.mk. If you wish to
use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
as well.
20140430:
The lindev device has been removed since /dev/full has been made a
standard device. __FreeBSD_version has been bumped.
20140424:
The knob WITHOUT_VI was added to the base system, which controls
building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
in order to reorder files share/termcap and didn't build ex(1) as a
build tool, so building/installing with WITH_VI is highly advised for
build hosts for older releases.
This issue has been fixed in stable/9 and stable/10 in r277022 and
r276991, respectively.
20140418:
The YES_HESIOD knob has been removed. It has been obsolete for
a decade. Please move to using WITH_HESIOD instead or your builds
will silently lack HESIOD.
20140405:
The uart(4) driver has been changed with respect to its handling
of the low-level console. Previously the uart(4) driver prevented
any process from changing the baudrate or the CLOCAL and HUPCL
control flags. By removing the restrictions, operators can make
changes to the serial console port without having to reboot.
However, when getty(8) is started on the serial device that is
associated with the low-level console, a misconfigured terminal
line in /etc/ttys will now have a real impact.
Before upgrading the kernel, make sure that /etc/ttys has the
serial console device configured as 3wire without baudrate to
preserve the previous behaviour. E.g:
ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
20140306:
Support for libwrap (TCP wrappers) in rpcbind was disabled by default
to improve performance. To re-enable it, if needed, run rpcbind
with command line option -W.
20140226:
Switched back to the GPL dtc compiler due to updates in the upstream
dts files not being supported by the BSDL dtc compiler. You will need
to rebuild your kernel toolchain to pick up the new compiler. Core dumps
may result while building dtb files during a kernel build if you fail
to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
20140216:
Clang and llvm have been upgraded to 3.4 release.
20140216:
The nve(4) driver has been removed. Please use the nfe(4) driver
for NVIDIA nForce MCP Ethernet adapters instead.
20140212:
An ABI incompatibility crept into the libc++ 3.4 import in r261283.
This could cause certain C++ applications using shared libraries built
against the previous version of libc++ to crash. The incompatibility
has now been fixed, but any C++ applications or shared libraries built
between r261283 and r261801 should be recompiled.
20140204:
OpenSSH will now ignore errors caused by kernel lacking of Capsicum
capability mode support. Please note that enabling the feature in
kernel is still highly recommended.
20140131:
OpenSSH is now built with sandbox support, and will use sandbox as
the default privilege separation method. This requires Capsicum
capability mode support in kernel.
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.
