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:
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/current-stable.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: ******************************
20180517:
The vxge(4) driver has been removed. This driver was introduced into
HEAD one week before the Exar left the Ethernet market and is not
known to be used. If you have device vxge in your kernel config file
it must be removed.
20180510:
The amd64 kernel now requires a ld that supports ifunc to produce a
working kernel, either lld or a newer binutils. lld is built by default
on amd64, and the 'buildkernel' target uses it automatically. However,
it is not the default linker, so building the kernel the traditional
way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
binutils port/package). lld will soon be default, and this requirement
will go away.
20180508:
The nxge(4) driver has been removed. This driver was for PCI-X 10g
cards made by s2io/Neterion. The company was aquired by Exar and
no longer sells or supports Ethernet products. If you have device
nxge in your kernel config file it must be removed.
20180504:
The tz database (tzdb) has been updated to 2018e. This version more
correctly models time stamps in time zones with negative DST such as
Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
time zone abbreviations and the tm_isdst flag.
20180502:
The ixgb(4) driver has been removed. This driver was for an early and
uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
quickly shifted to the long lived ixgbe family. If you have device
ixgb in your kernel config file it must be removed.
20180501:
The lmc(4) driver has been removed. This was a WAN interface
card that was already reportedly rare in 2003, and had an ambiguous
license. If you have device lmc in your kernel config file it must
be removed.
20180413:
Support for Arcnet networks has been removed. If you have device
arcnet or device cm in your kernel config file they must be
removed.
20180411:
Support for FDDI networks has been removed. If you have device
fddi or device fpa in your kernel config file they must be
removed.
20180406:
In addition to supporting RFC 3164 formatted messages, the
syslogd(8) service is now capable of parsing RFC 5424 formatted
log messages. The main benefit of using RFC 5424 is that clients
may now send log messages with timestamps containing year numbers,
microseconds and time zone offsets.
Similarly, the syslog(3) C library function has been altered to
send RFC 5424 formatted messages to the local system logging
daemon. On systems using syslogd(8), this change should have no
negative impact, as long as syslogd(8) and the C library are
updated at the same time. On systems using a different system
logging daemon, it may be necessary to make configuration
adjustments, depending on the software used.
When using syslog-ng, add the 'syslog-protocol' flag to local
input sources to enable parsing of RFC 5424 formatted messages:
source src {
unix-dgram("/var/run/log" flags(syslog-protocol));
}
When using rsyslog, disable the 'SysSock.UseSpecialParser' option
of the 'imuxsock' module to let messages be processed by the
regular RFC 3164/5424 parsing pipeline:
module(load="imuxsock" SysSock.UseSpecialParser="off")
Do note that these changes only affect communication between local
applications and syslogd(8). The format that syslogd(8) uses to
store messages on disk or forward messages to other systems
remains unchanged. syslogd(8) still uses RFC 3164 for these
purposes. Options to customize this behaviour will be added in the
future. Utilities that process log files stored in /var/log are
thus expected to continue to function as before.
__FreeBSD_version has been incremented to 1200061 to denote this
change.
20180328:
Support for token ring networks has been removed. If you
have "device token" in your kernel config you should remove
it. No device drivers supported token ring.
20180323:
makefs was modified to be able to tag ISO9660 El Torito boot catalog
entries as EFI instead of overloading the i386 tag as done previously.
The amd64 mkisoimages.sh script used to build amd64 ISO images for
release was updated to use this. This may mean that makefs must be
updated before "make cdrom" can be run in the release directory. This
should be as simple as:
$ cd $SRCDIR/usr.sbin/makefs
$ make depend all install
20180212:
FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
Co-existance for the transition period will come shortly. Booting is a
complex environment and test coverage for Lua-enabled loaders has been
thin, so it would be prudent to assume it might not work and make
provisions for backup boot methods.
20180211:
devmatch functionality has been turned on in devd. It will automatically
load drivers for unattached devices. This may cause unexpected drivers to

20180114:
Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
6.0.0. Please see the 20141231 entry below for information about
prerequisites and upgrading, if you are not already using clang 3.5.0
or higher.
20180110:
LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
This means it is used to link the kernel and userland libraries and
executables, but is not yet installed as /usr/bin/ld by default.
To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
WITHOUT_LLD_BOOTSTRAP=yes
20180110:
On i386, pmtimer has been removed. Its functionality has been folded
into apm. It was a no-op on ACPI in current for a while now (but was still
needed on i386 in FreeBSD 11 and earlier). Users may need to remove it
from kernel config files.
20180104:
The use of RSS hash from the network card aka flowid has been
disabled by default for lagg(4) as it's currently incompatible with
the lacp and loadbalance protocols.
This can be re-enabled by setting the following in loader.conf:
net.link.lagg.default_use_flowid="1"
20180102:
The SW_WATCHDOG option is no longer necessary to enable the
hardclock-based software watchdog if no hardware watchdog is
configured. As before, SW_WATCHDOG will cause the software
watchdog to be enabled even if a hardware watchdog is configured.
20171215:
r326887 fixes the issue described in the 20171214 UPDATING entry.
r326888 flips the switch back to building GELI support always.
20171214:
r362593 broke ZFS + GELI support for reasons unknown. However,
it also broke ZFS support generally, so GELI has been turned off
by default as the lesser evil in r326857. If you boot off ZFS and/or
GELI, it might not be a good time to update.
20171125:
PowerPC users must update loader(8) by rebuilding world before
installing a new kernel, as the protocol connecting them has
changed. Without the update, loader metadata will not be passed
successfully to the kernel and users will have to enter their
root partition at the kernel mountroot prompt to continue booting.
Newer versions of loader can boot old kernels without issue.
20171110:
The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
to WITH/OUT_LOADER_GELI.
20171106:
The naive and non-compliant support of posix_fallocate(2) in ZFS
has been removed as of r325320. The system call now returns EINVAL
when used on a ZFS file. Although the new behavior complies with the
standard, some consumers are not prepared to cope with it.
One known victim is lld prior to r325420.
20171102:
Building in a FreeBSD src checkout will automatically create object
directories now rather than store files in the current directory if
'make obj' was not ran. Calling 'make obj' is no longer necessary.
This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
/etc/src-env.conf (not /etc/src.conf), or passing the option in the
environment.
20171101:
The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
/usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
The UNIFIED_OBJDIR option is a transitional feature that will be
removed for 12.0 release; please migrate to the new format for any
tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
than hardcoding paths.
20171028:
The native-xtools target no longer installs the files by default to the
OBJDIR. Use the native-xtools-install target with a DESTDIR to install
to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
20171021:
As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
options are changing from controlling the build if defined / undefined
to controlling the build with explicit 'yes' or 'no' values. They will
shift to WITH/WITHOUT options to match other options in the system.
20171010:
libstand has turned into a private library for sys/boot use only.
It is no longer supported as a public interface outside of sys/boot.
20171005:
The arm port has split armv6 into armv6 and armv7. armv7 is now
a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
and are running a kernel from before r324363, you will need to add
MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
20171003:
When building multiple kernels using KERNCONF, non-existent KERNCONF
files will produce an error and buildkernel will fail. Previously
missing KERNCONF files silently failed giving no indication as to
why, only to subsequently discover during installkernel that the
desired kernel was never built in the first place.
20170912:
The default serial number format for CTL LUNs has changed. This will
affect users who use /dev/diskid/* device nodes, or whose FibreChannel
or iSCSI clients care about their LUNs' serial numbers. Users who
require serial number stability should hardcode serial numbers in
/etc/ctl.conf .
20170912:
For 32-bit arm compiled for hard-float support, soft-floating point
binaries now always get their shared libraries from
LD_SOFT_LIBRARY_PATH (in the past, this was only used if
/usr/libsoft also existed). Only users with a hard-float ld.so, but
soft-float everything else should be affected.
20170826:
The geli password typed at boot is now hidden. To restore the previous
behavior, see geli(8) for configuration options.
20170825:
Move PMTUD blackhole counters to TCPSTATS and remove them from bare
sysctl values. Minor nit, but requires a rebuild of both world/kernel
to complete.
20170814:
"make check" behavior (made in ^/head@r295380) has been changed to
execute from a limited sandbox, as opposed to executing from
${TESTSDIR}.
Behavioral changes:
- The "beforecheck" and "aftercheck" targets are now specified.
- ${CHECKDIR} (added in commit noted above) has been removed.
- Legacy behavior can be enabled by setting
WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
If the limited sandbox mode is enabled, "make check" will execute
"make distribution", then install, execute the tests, and clean up the
sandbox if successful.
The "make distribution" and "make install" targets are typically run as
root to set appropriate permissions and ownership at installation time.
The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
environment if executing "make check" with limited sandbox mode using
an unprivileged user.
20170808:
Since the switch to GPT disk labels, fsck for UFS/FFS has been
unable to automatically find alternate superblocks. As of r322297,
the information needed to find alternate superblocks has been
moved to the end of the area reserved for the boot block.
Filesystems created with a newfs of this vintage or later
will create the recovery information. If you have a filesystem
created prior to this change and wish to have a recovery block
created for your filesystem, you can do so by running fsck in
foreground mode (i.e., do not use the -p or -y options). As it
starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
to which you should answer yes.
20170728:
As of r321665, an NFSv4 server configuration that services
Kerberos mounts or clients that do not support the uid/gid in
owner/owner_group string capability, must explicitly enable
the nfsuserd daemon by adding nfsuserd_enable="YES" to the
machine's /etc/rc.conf file.
20170722:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20170701:
WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
r-commands (rlogin, rsh, etc.) to be built with the base system.
20170625:
The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
a very major ABI incompatible change, so users of FreeBSD/powerpc must
be careful when performing source upgrades. It is best to run
'make installworld' from an alternate root system, either a live
CD/memory stick, or a temporary root partition. Additionally, all ports
must be recompiled. powerpc64 is largely unaffected, except in the case
of 32-bit compatibility. All 32-bit binaries will be affected.
20170623:
Forward compatibility for the "ino64" project have been committed. This
will allow most new binaries to run on older kernels in a limited
fashion. This prevents many of the common foot-shooting actions in the
upgrade as well as the limited ability to roll back the kernel across
the ino64 upgrade. Complicated use cases may not work properly, though
enough simpler ones work to allow recovery in most situations.
20170620:
Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
if you require the GPL compiler.
20170618:
The internal ABI used for communication between the NFS kernel modules
was changed by r320085, so __FreeBSD_version was bumped to
ensure all the NFS related modules are updated together.
20170617:
The ABI of struct event was changed by extending the data
member to 64bit and adding ext fields. For upgrade, same
precautions as for the entry 20170523 "ino64" must be
followed.
20170531:
The GNU roff toolchain has been removed from base. To render manpages
which are not supported by mandoc(1), man(1) can fallback on GNU roff
from ports (and recommends to install it).
To render roff(7) documents, consider using GNU roff from ports or the
heirloom doctools roff toolchain from ports via pkg install groff or
via pkg install heirloom-doctools.
20170524:
The ath(4) and ath_hal(4) modules now build piecemeal to allow for
smaller runtime footprint builds. This is useful for embedded systems
which only require one chipset support.
If you load it as a module, make sure this is in /boot/loader.conf:
if_ath_load="YES"
This will load the HAL, all chip/RF backends and if_ath_pci.
If you have if_ath_pci in /boot/loader.conf, ensure it is after
if_ath or it will not load any HAL chipset support.
If you want to selectively load things (eg on ye cheape ARM/MIPS
platforms where RAM is at a premium) you should:
* load ath_hal
* load the chip modules in question
* load ath_rate, ath_dfs
* load ath_main
* load if_ath_pci and/or if_ath_ahb depending upon your particular
bus bind type - this is where probe/attach is done.
For further comments/feedback, poke adrian@ .
20170523:
The "ino64" 64-bit inode project has been committed, which extends
a number of types to 64 bits. Upgrading in place requires care and
adherence to the documented upgrade procedure.
If using a custom kernel configuration ensure that the
COMPAT_FREEBSD11 option is included (as during the upgrade the
system will be running the ino64 kernel with the existing world).
For the safest in-place upgrade begin by removing previous build
artifacts via "rm -rf /usr/obj/*". Then, carefully follow the
full procedure documented below under the heading "To rebuild
everything and install it on the current system." Specifically,
a reboot is required after installing the new kernel before
installing world.
20170424:
The NATM framework including the en(4), fatm(4), hatm(4), and
patm(4) devices has been removed. Consumers should plan a
migration before the end-of-life date for FreeBSD 11.
20170420:
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.
20170413:
As of r316810 for ipfilter, keep frags is no longer assumed when
keep state is specified in a rule. r316810 aligns ipfilter with
documentation in man pages separating keep frags from keep state.
This allows keep state to be specified without forcing keep frags
and allows keep frags to be specified independently of keep state.
To maintain previous behaviour, also specify keep frags with
keep state (as documented in ipf.conf.5).
20170407:
arm64 builds now use the base system LLD 4.0.0 linker by default,
instead of requiring that the aarch64-binutils port or package be
installed. To continue using aarch64-binutils, set
CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
20170405:
The UDP optimization in entry 20160818 that added the sysctl
net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
packets will no longer be treated as L3 broadcast packets.
20170331:
Binds and sends to the loopback addresses, IPv6 and IPv4, will now
use any explicitly assigned loopback address available in the jail
instead of using the first assigned address of the jail.
20170329:
The ctl.ko module no longer implements the iSCSI target frontend:
cfiscsi.ko does instead.
If building cfiscsi.ko as a kernel module, the module can be loaded
via one of the following methods:
- `cfiscsi_load="YES"` in loader.conf(5).
- Add `cfiscsi` to `$kld_list` in rc.conf(5).
- ctladm(8)/ctld(8), when compiled with iSCSI support
(`WITH_ISCSI=yes` in src.conf(5))
Please see cfiscsi(4) for more details.
20170316:
The mmcsd.ko module now additionally depends on geom_flashmap.ko.
Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
same source (previously, the dependency of mmcsd.ko on mmc.ko was
missing, but mmcsd.ko now will refuse to load if it is incompatible
with mmc.ko).
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) supports the same hardware.
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 buildkernel KERNCONF=YOUR_KERNEL_HERE
make installkernel 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 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 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
