NOTE TO PEOPLE WHO THINK THAT FreeBSD 14.x IS SLOW:
|
|
FreeBSD 14.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 WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild
|
|
world, or to merely disable the most expensive debugging functionality
|
|
at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".)

CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g
|
|
to move to the standard uintXX_t types from the old, traditional
|
|
BSD u_intXX_t types. This should be a NOP, but may cause problems
|
|
for out of tree changes. The SIMs were not updated since most of
|
|
the old u_intXX_t uses weren't due to CAM interfaces.
|
|
|

20230629:
|
|
The heuristic for detecting old chromebooks with an EC bug that requires
|
|
atkbdc driver workarounds has changed. There should be no functional
|
|
change, but if your old chromebook's keyboard stops working, please
|
|
file a PR and assign it to imp.
|
|
|
|
20230623:
|
|
OpenSSL has been updated to version 3.0, including changes throughout
|
|
the base system. It is important to rebuild third-party software
|
|
after upgrading.
|
|
|
|
20230619:
|
|
To enable pf rdr rules for connections initiated from the host, pf
|
|
filter rules can be optionally enabled for packets delivered
|
|
locally. This can change the behavior of rules which match packets
|
|
delivered to lo0. To enable this feature:
|
|
|
|
sysctl net.pf.filter_local=1
|
|
service pf restart
|
|
|
|
When enabled, its best to ensure that packets delivered locally are not
|
|
filtered, e.g. by adding a 'skip on lo' rule.
|
|
|
|
20230613:
|
|
Improvements to libtacplus(8) mean that tacplus.conf(5) now
|
|
follows POSIX shell syntax rules. This may cause TACACS+
|
|
authentication to fail if the shared secret contains a single
|
|
quote, double quote, or backslash character which isn't
|
|
already properly quoted or escaped.
|
|
|
|
20230612:
|
|
Belatedly switch the default nvme block device on x86 from nvd to nda.
|
|
nda created nvd compatibility links by default, so this should be a
|
|
nop. If this causes problems for your application, set hw.nvme.use_nvd=1
|
|
in your loader.conf or add `options NVME_USE_NVD=1` to your kernel
|
|
config. To disable the nvd compatibility aliases, add
|
|
kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on
|
|
all non-x86 platforms for some time now. If you need to fall back,
|
|
please email imp@freebsd.org about why.
|
|
|
|
Encrypted swap partitions need to be changed from nvd to nda if you
|
|
migrate, or you need to use the above to switch back to nvd.
|
|
|
|
20230422:
|
|
Remove portsnap(8). Users are encouraged to obtain the ports tree
|
|
using git instead.
|
|
|
|
20230420:
|
|
Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging
|
|
eg.
|
|
make buildworld-jobs
|
|
runs
|
|
make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1
|
|
|
|
where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env.
|
|
|
|
20230316:
|
|
Video related devices for some arm devices have been renamed.
|
|
If you have a custom kernel config and want to use hdmi output on
|
|
IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and
|
|
"device imx6_ipu" to it.
|
|
If you have a custom kernel config and want to use hdmi output on
|
|
TI AM335X board you need to add "device tda19988" to it.
|
|
If you add "device hdmi" in it you need to remove it as it doesn't
|
|
exist anymore.
|
|
|
|
20230221:
|
|
Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4)
|
|
for details.
|
|
|
|
20230206:
|
|
sshd now defaults to having X11Forwarding disabled, following upstream.
|
|
Administrators who wish to enable X11Forwarding should add
|
|
`X11Forwarding yes` to /etc/ssh/sshd_config.
|
|
|
|
20230204:
|
|
Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default
|
|
to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4).
|
|
|
|
20230130:
|
|
As of commit 7c40e2d5f685, the dependency on netlink(4) has been added
|
|
to the linux_common(4) module. Users relying on linux_common may need
|
|
to complile netlink(4) module if it is not present in their kernel.
|
|
|
|
20230126:
|
|
The WITHOUT_CXX option has been removed. C++ components in the base
|
|
system are now built unconditionally.
|
|
|
|
20230113:
|
|
LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled.
|
|
Bump _FreeBSD_version to 1400078 to be able to detect this change.
|
|
|
|
20221212:
|
|
llvm-objump is now always installed as objdump. Previously there was
|
|
no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used.
|
|
|
|
Some LLVM objdump options have a different output format compared to
|
|
GNU objdump; readelf is available for inspecting ELF files, and GNU
|
|
objdump is available from the devel/binutils port or package.
|
|
|
|
20221205:
|
|
dma(8) has replaced sendmail(8) as the default mta. For people willing
|
|
to reenable sendmail(8):
|
|
|
|
$ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf
|
|
|
|
and add sendmail_enable="YES" to rc.conf.
|
|
|
|
20221204:
|
|
hw.bus.disable_failed_devices has changed from 'false' to 'true' by
|
|
default. Now if newbus succeeds in probing a device, but fails to attach
|
|
the device, we'll disable the device. In the past, we'd keep retrying
|
|
the device on each new driver loaded. To get that behavior now, one
|
|
needs to use devctl to re-enable the device, and reprobe it (or set
|
|
the sysctl/tunable hw.bus.disable_failed_devices=false).
|
|
|
|
NOTE: This was reverted 20221205 due to unexpected compatibility issues
|
|
|
|
20221122:
|
|
pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'.
|
|
These configurations are no longer automatically reinterpreted as
|
|
'scrub fragment reassemble'.
|
|
|
|
20221121:
|
|
The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled
|
|
it is always installed as /usr/bin/cc (and c++, cpp).
|
|
|
|
20221026:
|
|
Some programs have been moved into separate packages. It is recommended
|
|
for pkgbase users to do:
|
|
|
|
pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \
|
|
FreeBSD-devd FreeBSD-devmatch
|
|
|
|
after upgrading to restore all the component that were previously
|
|
installed.
|
|
|
|
20220610:
|
|
LinuxKPI pm.h changes require an update to the latest drm-kmod version
|
|
before re-compiling to avoid errors.
|
|
|
|
20211230:
|
|
The macros provided for the manipulation of CPU sets (e.g. CPU_AND)
|
|
have been modified to take 2 source arguments instead of only 1.
|
|
Externally maintained sources that use these macros will have to
|
|
be adapted. The FreeBSD version has been bumped to 1400046 to
|
|
reflect this change.
|
|
|
|
20211214:
|
|
A number of the kernel include files are able to be included by
|
|
themselves. A test has been added to buildworld to enforce this.
|
|
|
|
20211209:
|
|
Remove mips as a recognized target. This starts the decommissioning of
|
|
mips support in FreeBSD. mips related items will be removed wholesale in
|
|
the coming days and weeks.
|
|
|
|
This broke the NO_CLEAN build for some people. Either do a clean build
|
|
or touch
|
|
lib/clang/include/llvm/Config/Targets.def
|
|
lib/clang/include/llvm/Config/AsmParsers.def
|
|
lib/clang/include/llvm/Config/Disassemblers.def
|
|
lib/clang/include/llvm/Config/AsmPrinters.def
|
|
before the build to force everything to rebuild that needs to.
|
|
|
|
20211202:
|
|
Unbound support for RFC8375: The special-use domain 'home.arpa' is
|
|
by default blocked. To unblock it use a local-zone nodefault
|
|
statement in unbound.conf:
|
|
local-zone: "home.arpa." nodefault
|
|
|
|
Or use another type of local-zone to override with your choice.
|
|
|
|
The reason for this is discussed in Section 6.1 of RFC8375:
|
|
Because 'home.arpa.' is not globally scoped and cannot be secured
|
|
using DNSSEC based on the root domain's trust anchor, there is no way
|
|
to tell, using a standard DNS query, in which homenet scope an answer
|
|
belongs. Consequently, users may experience surprising results with
|
|
such names when roaming to different homenets.
|
|
|
|
20211110:
|
|
Commit b8d60729deef changed the TCP congestion control framework so
|
|
that any of the included congestion control modules could be
|
|
the single module built into the kernel. Previously newreno
|
|
was automatically built in through direct reference. As of
|
|
this commit you are required to declare at least one congestion
|
|
control module (e.g. 'options CC_NEWRENO') and to also declare a
|
|
default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\").
|
|
The GENERIC configuration includes CC_NEWRENO and defines newreno
|
|
as the default. If no congestion control option is built into the
|
|
kernel and you are including networking, the kernel compile will
|
|
fail. Also if no default is declared the kernel compile will fail.
|
|
|
|
20211118:
|
|
Mips has been removed from universe builds. It will be removed from the
|
|
tree shortly.
|
|
|
|
20211106:
|
|
Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE.
|
|
The NFS modules must be rebuilt from sources and any out
|
|
of tree file systems that implement their own VOP_ALLOCATE
|
|
may need to be modified.
|
|
|
|
20211022:
|
|
The synchronous PPP kernel driver sppp(4) has been removed.
|
|
The cp(4) and ce(4) drivers are now always compiled with netgraph(4)
|
|
support, formerly enabled by NETGRAPH_CRONYX option.
|
|
|
|
20211020:
|
|
sh(1) is now the default shell for the root user. To force root to use
|
|
the csh shell, please run the following command as root:
|
|
|
|
# chsh -s csh
|
|
|
|
20211004:
|
|
Ncurses distribution has been split between libtinfow and libncurses
|
|
with libncurses.so becoming a linker (ld) script to seamlessly link
|
|
to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect
|
|
this change.
|
|
|
|
20210923:
|
|
As of commit 8160a0f62be6, the dummynet module no longer depends on the
|
|
ipfw module. Dummynet can now be used by pf as well as ipfw. As such
|
|
users who relied on this dependency may need to include ipfw in the
|
|
list of modules to load on their systems.
|
|
|
|
20210922:
|
|
As of commit 903873ce1560, the mixer(8) utility has got a slightly
|
|
new syntax. Please refer to the mixer(8) manual page for more
|
|
information. The old mixer utility can be installed from ports:
|
|
audio/freebsd-13-mixer
|
|
|
|
20210911:
|
|
As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has
|
|
been deleted from the nfscommon.ko. As such, nfsd.ko must be built
|
|
from up to date sources to avoid an undefined reference when
|
|
being loaded.
|
|
|
|
20210817:
|
|
As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS
|
|
by default. Users can enable kernel TLS via the "KTLS" SSL
|
|
option. This can be enabled globally by using a custom
|
|
OpenSSL config file via OPENSSL_CONF or via an
|
|
application-specific configuration option for applications
|
|
which permit setting SSL options via SSL_CONF_cmd(3).
|
|
|
|
20210811:
|
|
Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS
|
|
modules. Therefore, all need to be rebuilt from sources.
|
|
|
|
20210730:
|
|
Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl.
|
|
As of be70c7a50d32 it is no longer used by userspace, but it does mean
|
|
users may not be able to enumerate pf states if they update the kernel
|
|
past b69019c14cd8 without first updating userspace past be70c7a50d32.
|
|
|
|
20210729:
|
|
As of commit 01ad0c007964 if_bridge member interfaces can no longer
|
|
change their MTU. Changing the MTU of the bridge itself will change the
|
|
MTU on all member interfaces instead.
|
|
|
|
20210716:
|
|
Commit ee29e6f31111 changed the internal KAPI between the nfscommon
|
|
and nfsd modules. Therefore, both need to be rebuilt from sources.
|
|
Bump __FreeBSD_version to 1400026 for this KAPI change.
|
|
|
|
20210715:
|
|
The 20210707 awk update brought in a change in behavior. This has
|
|
been corrected as of d4d252c49976. Between these dates, if you
|
|
installed a new awk binary, you may not be able to build a new
|
|
kernel because the change in behavior affected the genoffset
|
|
script used to build the kernel. If you did update, the fix is
|
|
to update your sources past the above hash and do
|
|
% cd usr.bin/awk
|
|
% make clean all
|
|
% sudo -E make install
|
|
to enable building kernels again.
|
|
|
|
20210708:
|
|
Commit 1e0a518d6548 changed the internal KAPI between the NFS
|
|
modules. They all need to be rebuilt from sources. I did not
|
|
bump __FreeBSD_version, since it was bumped recently.
|
|
|
|
20210707:
|
|
awk has been updated to the latest one-true-awk version 20210215.
|
|
This contains a number of minor bug fixes.
|
|
|
|
20210624:
|
|
The NFSv4 client now uses the highest minor version of NFSv4
|
|
supported by the NFSv4 server by default instead of minor version 0,
|
|
for NFSv4 mounts.
|
|
The "minorversion" mount option may be used to override this default.
|
|
|
|
20210618:
|
|
Bump __FreeBSD_version to 1400024 for LinuxKPI changes.
|
|
Most notably netdev.h can change now as the (last) dependencies
|
|
(mlx4/ofed) are now using struct ifnet directly, but also for PCI
|
|
additions and others.
|
|
|
|
20210618:
|
|
The directory "blacklisted" under /usr/share/certs/ has been
|
|
renamed to "untrusted".
|
|
|
|
20210611:
|
|
svnlite has been removed from base. Should you need svn for any reason
|
|
please install the svn package or port.
|
|
|
|
20210611:
|
|
Commit e1a907a25cfa changed the internal KAPI between the krpc
|
|
and nfsserver. As such, both modules must be rebuilt from
|
|
sources. Bump __FreeBSD_version to 1400022.
|
|
|
|
20210610:
|
|
The an(4) driver has been removed from FreeBSD.
|
|
|
|
20210608:
|
|
The vendor/openzfs branch was renamed to vendor/openzfs/legacy to
|
|
start tracking OpenZFS upstream more closely. Please see
|
|
https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html
|
|
for details on how to correct any errors that might result. The
|
|
short version is that you need to remove the old branch locally:
|
|
git update-ref -d refs/remotes/freebsd/vendor/openzfs
|
|
(assuming your upstream origin is named 'freebsd').
|
|
|
|
20210525:
|
|
Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI
|
|
which break drm-kmod. In addition various other additions where
|
|
committed. Bump __FreeBSD_version to 1400015 to be able to
|
|
detect this.
|
|
|
|
20210513:
|
|
Commit ca179c4d74f2 changed the package in which the OpenSSL
|
|
libraries and utilities are packaged.
|
|
It is recommended for pkgbase user to do:
|
|
pkg install -f FreeBSD-openssl
|
|
before pkg upgrade otherwise some dependencies might not be met
|
|
and pkg will stop working as libssl will not be present anymore
|
|
on the system.
|
|
|
|
20210426:
|
|
Commit 875977314881 changed the internal KAPI between
|
|
the nfsd and nfscommon modules. As such these modules
|
|
need to be rebuilt from sources.
|
|
Without this patch in your NFSv4.1/4.2 server, enabling
|
|
delegations by setting vfs.nfsd.issue_delegations non-zero
|
|
is not recommended.
|
|
|
|
20210411:
|
|
Commit 7763814fc9c2 changed the internal KAPI between
|
|
the krpc and NFS. As such, the krpc, nfscommon and
|
|
nfscl modules must all be rebuilt from sources.
|
|
Without this patch, NFSv4.1/4.2 mounts should not
|
|
be done with the nfscbd(8) daemon running, to avoid
|
|
needing a working back channel for server->client RPCs.
|
|
|
|
20210330:
|
|
Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it
|
|
handles binding of the back channel as required by RFC5661.
|
|
Until this patch is in your server, avoid use of the "nconnects"
|
|
mount option for Linux NFSv4.1/4.2 mounts.
|
|
|
|
20210225:
|
|
For 64-bit architectures the base system is now built with Position
|
|
Independent Executable (PIE) support enabled by default. It may be
|
|
disabled using the WITHOUT_PIE knob. A clean build is required.
|
|
|
|
20210128:
|
|
Various LinuxKPI functionality was added which conflicts with DRM.
|
|
Please update your drm-kmod port to after the __FreeBSD_version 1400003
|
|
update.
|
|
|
|
20210108:
|
|
PC Card attachments for all devices have been removed. In the case of
|
|
wi and cmx, the entire drivers were removed because they were only
|
|
PC Card devices. FreeBSD_version 1300134 should be used for this
|
|
since it was bumped so recently.
|
|
|
|
20210107:
|
|
Transport-independent parts of HID support have been split off the USB
|
|
code in to separate subsystem. Kernel configs which include one of
|
|
ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
|
|
be updated with adding of "device hid" line.
|
|
|
|
20210105:
|
|
ncurses installation has been modified to only keep the widechar
|
|
enabled version. Incremental build is broken for that change, so it
|
|
requires a clean build.
|
|
|
|
20201223:
|
|
The FreeBSD project has migrated from Subversion to Git. Temporary
|
|
instructions can be found at
|
|
https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
|
|
and other documents in that repo.

20201216:
|
|
The services database has been updated to cover more of the basic
|
|
services expected in a modern system. The database is big enough
|
|
that it will cause issues in mergemaster in Releases previous to
|
|
12.2 and 11.3, or in very old current systems from before r358154.
|
|

20201215:
|
|
Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
|
|
may be installed from ports or packages.
|
|
|
|
20201124:
|
|
ping6 has been merged into ping. It can now be called as "ping -6".
|
|
See ping(8) for details.
|
|
|
|
20201108:
|
|
Default value of net.add_addr_allfibs has been changed to 0.
|
|
If you have multi-fib configuration and rely on existence of all
|
|
interface routes in every fib, you need to set the above sysctl to 1.
|
|
|
|
20201030:
|
|
The internal pre-processor in the calendar(1) program has been
|
|
extended to support more C pre-processor commands (e.g. #ifdef, #else,
|
|
and #undef) and to detect unbalanced conditional statements.
|
|
Error messages have been extended to include the filename and line
|
|
number if processing stops to help fixing malformed data files.
|
|
|
|
20201026:
|
|
All the data files for the calendar(1) program, except calendar.freebsd,
|
|
have been moved to the deskutils/calendar-data port, much like the
|
|
jewish calendar entries were moved to deskutils/hebcal years ago. After
|
|
make delete-old-files, you need to install it to retain full
|
|
functionality. calendar(1) will issue a reminder for files it can't
|
|
find.
|
|
|
|
20200923:
|
|
LINT files are no longer generated. We now include the relevant NOTES
|
|
files. Note: This may cause conflicts with updating in some cases.
|
|
find sys -name LINT\* -delete
|
|
is suggested across this commit to remove the generated LINT files.
|
|
|
|
If you have tried to update with generated files there, the svn
|
|
command you want to un-auger the tree is
|
|
cd sys/amd64/conf
|
|
svn revert -R .
|
|
and then do the above find from the top level. Substitute 'amd64'
|
|
above with where the error message indicates a conflict.
|
|
|
|
20200824:
|
|
OpenZFS support has been integrated. Do not upgrade root pools until
|
|
the loader is updated to support zstd. Furthermore, we caution against
|
|
'zpool upgrade' for the next few weeks. The change should be transparent
|
|
unless you want to use new features.
|
|
|
|
Not all "NO_CLEAN" build scenarios work across these changes. Many
|
|
scenarios have been tested and fixed, but rebuilding kernels without
|
|
rebuilding world may fail.
|
|
|
|
The ZFS cache file has moved from /boot to /etc to match the OpenZFS
|
|
upstream default. A fallback to /boot has been added for mountroot.
|
|
|
|
Pool auto import behavior at boot has been moved from the kernel module
|
|
to an explicit "zpool import -a" in one of the rc scripts enabled by
|
|
zfs_enable=YES. This means your non-root zpools won't auto import until
|
|
you upgrade your /etc/rc.d files.
|
|
|
|
20200824:
|
|
The resume code now notifies devd with the 'kernel' system
|
|
rather than the old 'kern' subsystem to be consistent with
|
|
other use. The old notification will be created as well, but
|
|
will be removed prior to FreeBSD 14.0.
|
|
|
|
20200821:
|
|
r362275 changed the internal API between the kernel RPC and the
|
|
NFS modules. As such, all the modules must be recompiled from
|
|
sources.
|
|
|
|
20200817:
|
|
r364330 modified the internal API used between the NFS modules.
|
|
As such, all the NFS modules must be re-compiled from sources.
|
|
|
|
20200816:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 11.0.0. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20200810:
|
|
r364092 modified the internal ABI used between the kernel NFS
|
|
modules. As such, all of these modules need to be rebuilt
|
|
from sources, so a version bump was done.
|
|
|
|
20200807:
|
|
Makefile.inc has been updated to work around the issue documented in
|
|
20200729. It was a case where the optimization of using symbolic links
|
|
to point to binaries created a situation where we'd run new binaries
|
|
with old libraries starting midway through the installworld process.
|
|
|
|
20200729:
|
|
r363679 has redefined some undefined behavior in regcomp(3); notably,
|
|
extraneous escapes of most ordinary characters will no longer be
|
|
accepted. An exp-run has identified all of the problems with this in
|
|
ports, but other non-ports software may need extra escapes removed to
|
|
continue to function.
|
|
|
|
Because of this change, installworld may encounter the following error
|
|
from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
|
|
you do not halt installworld. Instead, let it run to completion (whether
|
|
successful or not) and run installworld once more.
|
|
|
|
20200627:
|
|
A new implementation of bc and dc has been imported in r362681. This
|
|
implementation corrects non-conformant behavior of the previous bc
|
|
and adds GNU bc compatible options. It offers a number of extensions,
|
|
is much faster on large values, and has support for message catalogs
|
|
(a number of languages are already supported, contributions of further
|
|
languages welcome). The option WITHOUT_GH_BC can be used to build the
|
|
world with the previous versions of bc and dc.
|
|
|
|
20200625:
|
|
r362639 changed the internal API used between the NFS kernel modules.
|
|
As such, they all need to be rebuilt from sources.
|
|
|
|
20200613:
|
|
r362158 changed the arguments for VFS_CHECKEXP(). As such, any
|
|
out of tree file systems need to be modified and rebuilt.
|
|
Also, any file systems that are modules must be rebuilt.
|
|
|
|
20200604:
|
|
read(2) of a directory fd is now rejected by default. root may
|
|
re-enable it for system root only on non-ZFS filesystems with the
|
|
security.bsd.allow_read_dir sysctl(8) MIB if
|
|
security.bsd.suser_enabled=1.
|
|
|
|
It may be advised to setup aliases for grep to default to `-d skip` if
|
|
commonly non-recursively grepping a list that includes directories and
|
|
the potential for the resulting stderr output is not tolerable. Example
|
|
aliases are now installed, commented out, in /root/.cshrc and
|
|
/root/.shrc.
|
|
|
|
20200523:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 10.0.1. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20200512:
|
|
Support for obsolete compilers has been removed from the build system.
|
|
Clang 6 and GCC 6.4 are the minimum supported versions.
|
|
|
|
20200424:
|
|
closefrom(2) has been moved under COMPAT12, and replaced in libc with a
|
|
stub that calls close_range(2). If using a custom kernel configuration,
|
|
you may want to ensure that the COMPAT_FREEBSD12 option is included, as
|
|
a slightly older -CURRENT userland and older FreeBSD userlands may not
|
|
be functional without closefrom(2).
|
|
|
|
20200414:
|
|
Upstream DTS from Linux 5.6 was merged and they now have the SID
|
|
and THS (Secure ID controller and THermal Sensor) node present.
|
|
The DTB overlays have now been removed from the tree for the H3/H5 and
|
|
A64 SoCs and the aw_sid and aw_thermal driver have been updated to
|
|
deal with upstream DTS. If you are using those overlays you need to
|
|
remove them from loader.conf and update the DTBs on the FAT partition.
|
|
|
|
20200310:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 10.0.0. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20200309:
|
|
The amd(8) automount daemon has been removed from the source tree.
|
|
As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
|
|
amd is still available in the sysutils/am-utils port.
|
|
|
|
20200301:
|
|
Removed brooktree driver (bktr.4) from the tree.
|
|
|
|
20200229:
|
|
The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
|
|
compiler in usr.bin/dtc is used on all architectures which use dtc, and
|
|
the GPL dtc is available (if needed) from the sysutils/dtc port.
|
|
|
|
20200229:
|
|
The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
|
|
is used by all supported CPU architectures.
|
|
|
|
20200229:
|
|
GCC 4.2.1 has been removed from the tree. The WITH_GCC,
|
|
WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
|
|
Users who wish to build FreeBSD with GCC must use the external toolchain
|
|
ports or packages.
|
|
|
|
20200220:
|
|
ncurses has been updated to a newer version (6.2-20200215). Given the ABI
|
|
has changed, users will have to rebuild all the ports that are linked to
|
|
ncurses.
|
|
|
|
20200217:
|
|
The size of struct vnet and the magic cookie have changed.
|
|
Users need to recompile libkvm and all modules using VIMAGE
|
|
together with their new kernel.
|
|
|
|
20200212:
|
|
Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
|
|
NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
|
|
your Makefiles and scripts to define MK_<var>=no instead as required.
|
|
|
|
One exception to this is that program or library Makefiles should
|
|
define MAN to empty rather than setting MK_MAN=no.
|
|
|
|
20200108:
|
|
Clang/LLVM is now the default compiler and LLD the default
|
|
linker for riscv64.
|
|
|
|
20200107:
|
|
make universe no longer uses GCC 4.2.1 on any architectures.
|
|
Architectures not supported by in-tree Clang/LLVM require an
|
|
external toolchain package.
|
|
|
|
20200104:
|
|
GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
|
|
retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
|
|
options default to off for all supported CPU architectures. As a
|
|
short-term transition aid they may be enabled via WITH_* options.
|
|
GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
|
|
|
|
20200102:
|
|
Support for armv5 has been disconnected and is being removed. The
|
|
machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
|
|
You must now use a MACHINE_ARCH of armv6 or armv7. The default
|
|
MACHINE_ARCH for MACHINE=arm is now armv7.
|
|
|
|
20191226:
|
|
Clang/LLVM is now the default compiler for all powerpc architectures.
|
|
LLD is now the default linker for powerpc64. The change for powerpc64
|
|
also includes a change to the ELFv2 ABI, incompatible with the existing
|
|
ABI.
|
|
|
|
20191226:
|
|
Kernel-loadable random(4) modules are no longer unloadable.
|
|
|
|
20191222:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 9.0.1. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20191212:
|
|
r355677 has modified the internal interface used between the
|
|
NFS modules in the kernel. As such, they must all be upgraded
|
|
simultaneously. I will do a version bump for this.
|
|
|
|
20191205:
|
|
The root certificates of the Mozilla CA Certificate Store have been
|
|
imported into the base system and can be managed with the certctl(8)
|
|
utility. If you have installed the security/ca_root_nss port or package
|
|
with the ETCSYMLINK option (the default), be advised that there may be
|
|
differences between those included in the port and those included in
|
|
base due to differences in nss branch used as well as general update
|
|
frequency. Note also that certctl(8) cannot manage certs in the
|
|
format used by the security/ca_root_nss port.
|
|
|
|
20191120:
|
|
The amd(8) automount daemon has been disabled by default, and will be
|
|
removed in the future. As of FreeBSD 10.1 the autofs(5) is available
|
|
for automounting.
|
|
|
|
20191107:
|
|
The nctgpio and wbwd drivers have been moved to the superio bus.
|
|
If you have one of these drivers in a kernel configuration, then
|
|
you should add device superio to it. If you use one of these drivers
|
|
as a module and you compile a custom set of modules, then you should
|
|
add superio to the set.
|
|
|
|
20191021:
|
|
KPIs for network drivers to access interface addresses have changed.
|
|
Users need to recompile NIC driver modules together with kernel.
|
|
|
|
20191021:
|
|
The net.link.tap.user_open sysctl no longer prevents user opening of
|
|
already created /dev/tapNN devices. Access is still controlled by
|
|
node permissions, just like tun devices. The net.link.tap.user_open
|
|
sysctl is now used only to allow users to perform devfs cloning of
|
|
tap devices, and the subsequent open may not succeed if the user is not
|
|
in the appropriate group. This sysctl may be deprecated/removed
|
|
completely in the future.
|
|
|
|
20191009:
|
|
mips, powerpc, and sparc64 are no longer built as part of
|
|
universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
|
|
not defined, mips, powerpc, and sparc64 builds will look for
|
|
the xtoolchain binaries and if installed use them for universe
|
|
builds. As llvm 9.0 becomes vetted for these architectures, they
|
|
will be removed from the list.
|
|
|
|
20191009:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 9.0.0. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20191003:
|
|
The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
|
|
GENERIC. They are available as modules and can be loaded by adding
|
|
to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
|
|
hptnr_load="YES", or hptrr_load="YES", respectively.
|
|
|
|
20190913:
|
|
ntpd no longer by default locks its pages in memory, allowing them
|
|
to be paged out by the kernel. Use rlimit memlock to restore
|
|
historic BSD behaviour. For example, add "rlimit memlock 32"
|
|
to ntp.conf to lock up to 32 MB of ntpd address space in memory.
|
|
|
|
20190823:
|
|
Several of ping6's options have been renamed for better consistency
|
|
with ping. If you use any of -ARWXaghmrtwx, you must update your
|
|
scripts. See ping6(8) for details.
|
|
|
|
20190727:
|
|
The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
|
|
and the "-o sync_unmount" and "-o init_backgrounded" mount options have
|
|
been removed from mount_fusefs(8). You can safely remove them from
|
|
your scripts, because they had no effect.
|
|
|
|
The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
|
|
vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
|
|
vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
|
|
sysctls have been removed. If you felt the need to set any of them to
|
|
a non-default value, please tell asomers@FreeBSD.org why.
|
|
|
|
20190713:
|
|
Default permissions on the /var/account/acct file (and copies of it
|
|
rotated by periodic daily scripts) are changed from 0644 to 0640
|
|
because the file contains sensitive information that should not be
|
|
world-readable. If the /var/account directory must be created by
|
|
rc.d/accounting, the mode used is now 0750. Admins who use the
|
|
accounting feature are encouraged to change the mode of an existing
|
|
/var/account directory to 0750 or 0700.
|
|
|
|
20190620:
|
|
Entropy collection and the /dev/random device are no longer optional
|
|
components. The "device random" option has been removed.
|
|
Implementations of distilling algorithms can still be made loadable
|
|
with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
|
|
|
|
20190612:
|
|
Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
|
|
been upgraded to 8.0.1. Please see the 20141231 entry below for
|
|
information about prerequisites and upgrading, if you are not already
|
|
using clang 3.5.0 or higher.
|
|
|
|
20190608:
|
|
A fix was applied to i386 kernel modules to avoid panics with
|
|
dpcpu or vnet. Users need to recompile i386 kernel modules
|
|
having pcpu or vnet sections or they will refuse to load.
|
|
|
|
20190513:
|
|
User-wired pages now have their own counter,
|
|
vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
|
|
to vm.max_user_wired and changed from an unsigned int to an unsigned
|
|
long. bhyve VMs wired with the -S are now subject to the user
|
|
wiring limit; the vm.max_user_wired sysctl may need to be tuned to
|
|
avoid running into the limit.
|
|
|
|
20190507:
|
|
The IPSEC option has been removed from GENERIC. Users requiring
|
|
ipsec(4) must now load the ipsec(4) kernel module.
|
|
|
|
20190507:
|
|
The tap(4) driver has been folded into tun(4), and the module has been
|
|
renamed to tuntap. You should update any kld_list="if_tap" or
|
|
kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
|
|
if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
|
|
module instead, and "device tap" or "device tun" entries in kernel
|
|
config files to select the tuntap device instead.
|
|
|
|
20190418:
|
|
The following knobs have been added related to tradeoffs between
|
|
safe use of the random device and availability in the absence of
|
|
entropy:
|
|
|
|
kern.random.initial_seeding.bypass_before_seeding: tunable; set
|
|
non-zero to bypass the random device prior to seeding, or zero to
|
|
block random requests until the random device is initially seeded.
|
|
For now, set to 1 (unsafe) by default to restore pre-r346250 boot
|
|
availability properties.
|
|
|
|
kern.random.initial_seeding.read_random_bypassed_before_seeding:
|
|
read-only diagnostic sysctl that is set when bypass is enabled and
|
|
read_random(9) is bypassed, to enable programmatic handling of this
|
|
initial condition, if desired.
|
|
|
|
kern.random.initial_seeding.arc4random_bypassed_before_seeding:
|
|
Similar to the above, but for arc4random(9) initial seeding.
|
|
|
|
kern.random.initial_seeding.disable_bypass_warnings: tunable; set
|
|
non-zero to disable warnings in dmesg when the same conditions are
|
|
met as for the diagnostic sysctls above. Defaults to zero, i.e.,
|
|
produce warnings in dmesg when the conditions are met.
|
|
|
|
20190416:
|
|
The loadable random module KPI has changed; the random_infra_init()
|
|
routine now requires a 3rd function pointer for a bool (*)(void)
|
|
method that returns true if the random device is seeded (and
|
|
therefore unblocked).
|
|
|
|
20190404:
|
|
r345895 reverts r320698. This implies that an nfsuserd(8) daemon
|
|
built from head sources between r320757 (July 6, 2017) and
|
|
r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
|
|
is added to the command line.
|
|
nfsuserd daemons built from head sources that are post-r338192 are
|
|
not affected and should continue to work.
|
|
|
|
20190320:
|
|
The fuse(4) module has been renamed to fusefs(4) for consistency with
|
|
other filesystems. You should update any kld_load="fuse" entries in
|
|
/etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
|
|
"options FUSE" entries in kernel config files.
|
|
|
|
20190304:
|
|
Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
|
|
8.0.0. Please see the 20141231 entry below for information about
|
|
prerequisites and upgrading, if you are not already using clang 3.5.0
|
|
or higher.
|
|
|
|
20190226:

|
geom_uzip(4) depends on the new module xz. If geom_uzip is statically
|
|
compiled into your custom kernel, add 'device xz' statement to the
|
|
kernel config.
|
|
|
|
20190219:
|
|
drm and drm2 have been removed from the tree. Please see
|
|
https://wiki.freebsd.org/Graphics for the latest information on
|
|
migrating to the drm ports.
|
|
|
|
20190131:
|
|
Iflib is no longer unconditionally compiled into the kernel. Drivers
|
|
using iflib and statically compiled into the kernel, now require
|
|
the 'device iflib' config option. For the same drivers loaded as
|
|
modules on kernels not having 'device iflib', the iflib.ko module
|
|
is loaded automatically.
|
|
|
|
20190125:
|
|
The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
|
|
options no longer exist since r343219 and r343427 respectively;
|
|
nothing uses them, so they should be just removed from custom
|
|
kernel config files.
|
|
|
|
20181230:
|
|
r342635 changes the way efibootmgr(8) works by requiring users to add
|
|
the -b (bootnum) parameter for commands where the bootnum was previously
|
|
specified with each option. For example 'efibootmgr -B 0001' is now
|
|
'efibootmgr -B -b 0001'.
|
|
|
|
20181220:
|
|
r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
|
|
in the same as it is applied to NFSv2 and 3. This implies that NFSv4
|
|
servers that have vfs.nfsd.nfs_privport set will only allow mounts
|
|
from clients using a reserved port. Since both the FreeBSD and Linux
|
|
NFSv4 clients use reserved ports by default, this should not affect
|
|
most NFSv4 mounts.
|
|
|
|
20181219:
|
|
The XLP config has been removed. We can't support 64-bit atomics in this
|
|
kernel because it is running in 32-bit mode. XLP users must transition
|
|
to running a 64-bit kernel (XLP64 or XLPN32).
|
|
|
|
The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
|
|
the preferred emulator today and we don't need two different ones.
|
|
|
|
The old sibyte / swarm / Broadcom BCM1250 support has been
|
|
removed from the mips port.
|
|
|
|
20181211:
|
|
Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
|
|
7.0.1. Please see the 20141231 entry below for information about
|
|
prerequisites and upgrading, if you are not already using clang 3.5.0
|
|
or higher.
|
|
|
|
20181211:
|
|
Remove the timed and netdate programs from the base tree. Setting
|
|
the time with these daemons has been obsolete for over a decade.
|
|
|
|
20181126:
|
|
On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
|
|
linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
|
|
it produces broken binaries when ifuncs are in use. Users needing
|
|
GNU ld should install the binutils port or package.
|
|
|
|
20181123:
|
|
The BSD crtbegin and crtend code has been enabled by default. It has
|
|
had extensive testing on amd64, arm64, and i386. It can be disabled
|
|
by building a world with -DWITHOUT_BSD_CRTBEGIN.
|
|
|
|
20181115:
|
|
The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
|
|
has been converted to a port (misc/ctm) and will be removed from
|
|
FreeBSD-13. It is available as a package (ctm) for all supported
|
|
FreeBSD versions.
|
|
|
|
20181110:
|
|
The default newsyslog.conf(5) file has been changed to only include
|
|
files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
|
|
the filenames end in '.conf' and do not begin with a '.'.
|
|
|
|
You should check the configuration files in these two directories match
|
|
this naming convention. You can verify which configuration files are
|
|
being included using the command:
|
|
$ newsyslog -Nrv
|
|
|
|
20181015:
|
|
Ports for the DRM modules have been simplified. Now, amd64 users should
|
|
just install the drm-kmod port. All others should install
|
|
drm-legacy-kmod.
|
|
|
|
Graphics hardware that's newer than about 2010 usually works with
|
|
drm-kmod. For hardware older than 2013, however, some users will need
|
|
to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
|
|
than 2008 usually only works in drm-legacy-kmod. The graphics team can
|
|
only commit to hardware made since 2013 due to the complexity of the
|
|
market and difficulty to test all the older cards effectively. If you
|
|
have hardware supported by drm-kmod, you are strongly encouraged to use
|
|
that as you will get better support.
|
|
|
|
Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
|
|
elsewhere, the drm and drm2 modules will be eliminated from the src base
|
|
soon (with a limited exception for arm). Please update to the package
|
|
asap and report any issues to x11@freebsd.org.
|
|
|
|
Generally, anybody using the drm*-kmod packages should add
|
|
WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
|
|
cross-threading surprises, especially with automatic driver
|
|
loading from X11 startup. These will become the defaults in 13-current
|
|
shortly.
|
|
|
|
20181012:
|
|
The ixlv(4) driver has been renamed to iavf(4). As a consequence,
|
|
custom kernel and module loading configuration files must be updated
|
|
accordingly. Moreover, interfaces previous presented as ixlvN to the
|
|
system are now exposed as iavfN and network configuration files must
|
|
be adjusted as necessary.
|
|
|
|
20181009:
|
|
OpenSSL has been updated to version 1.1.1. This update included
|
|
additional various API changes throughout the base system. It is
|
|
important to rebuild third-party software after upgrading. The value
|
|
of __FreeBSD_version has been bumped accordingly.
|
|
|
|
20181006:
|
|
The legacy DRM modules and drivers have now been added to the loader's
|
|
module blacklist, in favor of loading them with kld_list in rc.conf(5).
|
|
The module blacklist may be overridden with the loader.conf(5)
|
|
'module_blacklist' variable, but loading them via rc.conf(5) is strongly
|
|
encouraged.
|
|
|
|
20181002:
|
|
The cam(4) based nda(4) driver will be used over nvd(4) by default on
|
|
powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
|
|
loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
|
|
driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
|
|
nda device name.
|
|
|
|
20180913:
|
|
Reproducible build mode is now on by default, in preparation for
|
|
FreeBSD 12.0. This eliminates build metadata such as the user,
|
|
host, and time from the kernel (and uname), unless the working tree
|
|
corresponds to a modified checkout from a version control system.
|
|
The previous behavior can be obtained by setting the /etc/src.conf
|
|
knob WITHOUT_REPRODUCIBLE_BUILD.
|
|
|
|
20180826:
|
|
The Yarrow CSPRNG has been removed from the kernel as it has not been
|
|
supported by its designers since at least 2003. Fortuna has been the
|
|
default since FreeBSD-11.
|
|
|
|
20180822:
|
|
devctl freeze/thaw have gone into the tree, the rc scripts have been
|
|
updated to use them and devmatch has been changed. You should update
|
|
kernel, userland and rc scripts all at the same time.
|
|
|
|
20180818:
|
|
The default interpreter has been switched from 4th to Lua.
|
|
LOADER_DEFAULT_INTERP, documented in build(7), will override the default
|
|
interpreter. If you have custom FORTH code you will need to set
|
|
LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
|
|
src.conf for the build. This will create default hard links between
|
|
loader and loader_4th instead of loader and loader_lua, the new default.
|
|
If you are using UEFI it will create the proper hard link to loader.efi.
|
|
|
|
bhyve uses userboot.so. It remains 4th-only until some issues are solved
|
|
regarding coexisting with multiple versions of FreeBSD are resolved.
|
|
|
|
20180815:
|
|
ls(1) now respects the COLORTERM environment variable used in other
|
|
systems and software to indicate that a colored terminal is both
|
|
supported and desired. If ls(1) is suddenly emitting colors, they may
|
|
be disabled again by either removing the unwanted COLORTERM from your
|
|
environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
|
|
may not be observed in a future release.
|
|
|
|
20180808:
|
|
The default pager for most commands has been changed to "less". To
|
|
restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
|
|
your environment.
|
|
|
|
20180731:
|
|
The jedec_ts(4) driver has been removed. A superset of its functionality
|
|
is available in the jedec_dimm(4) driver, and the manpage for that
|
|
driver includes migration instructions. If you have "device jedec_ts"
|
|
in your kernel configuration file, it must be removed.
|
|
|
|
20180730:
|
|
amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
|
|
This should have no effect if the kernel is booted via BIOS/legacy boot.
|
|
EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
|
|
has a buggy firmware that prevents a successful boot due to use of
|
|
runtime services.
|
|
|
|
20180727:
|
|
Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
|
|
support has been removed from the tree. These ports were
|
|
obsolete and/or known to be broken for many years.
|
|
|
|
20180723:
|
|
loader.efi has been augmented to participate more fully in the
|
|
UEFI boot manager protocol. loader.efi will now look at the
|
|
BootXXXX environment variable to determine if a specific kernel
|
|
or root partition was specified. XXXX is derived from BootCurrent.
|
|
efibootmgr(8) manages these standard UEFI variables.
|
|
|
|
20180720:
|
|
zfsloader's functionality has now been folded into loader.
|
|
zfsloader is no longer necessary once you've updated your
|
|
boot blocks. For a transition period, we will install a
|
|
hardlink for zfsloader to loader to allow a smooth transition
|
|
until the boot blocks can be updated (hard link because old
|
|
zfs boot blocks don't understand symlinks).
|
|
|
|
20180719:
|
|
ARM64 now have efifb support, if you want to have serial console
|
|
on your arm64 board when an screen is connected and the bootloader
|
|
setup a frame buffer for us to use, just add :
|
|
boot_serial=YES
|
|
boot_multicons=YES
|
|
in /boot/loader.conf
|
|
For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
|
|
an screen connected as the firmware will setup a frame buffer are that
|
|
u-boot will expose as an EFI frame buffer.
|
|
|
|
20180719:
|
|
New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
|
|
or take steps to update /etc/passwd before doing installworld on
|
|
existing systems. Do not skip the "mergemaster -Fp" step before
|
|
installworld, as described in the update procedures near the bottom
|
|
of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
|
|
if the new mac_ntpd(4) policy is available, unless ntpd_flags or
|
|
the ntp config file contain options that change file/dir locations.
|
|
When such options (e.g., "statsdir" or "crypto") are used, ntpd can
|
|
still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
|
|
taking steps to ensure that all required files/dirs are accessible
|
|
by the ntpd user.
|
|
|
|
20180717:
|
|
Big endian arm support has been removed.
|
|
|
|
20180711:
|
|
The static environment setup in kernel configs is no longer mutually
|
|
exclusive with the loader(8) environment by default. In order to
|
|
restore the previous default behavior of disabling the loader(8)
|
|
environment if a static environment is present, you must specify
|
|
loader_env.disabled=1 in the static environment.
|
|
|
|
20180705:
|
|
The ABI of syscalls used by management tools like sockstat and
|
|
netstat has been broken to allow 32-bit binaries to work on
|
|
64-bit kernels without modification. These programs will need
|
|
to match the kernel in order to function. External programs may
|
|
require minor modifications to accommodate a change of type in
|
|
structures from pointers to 64-bit virtual addresses.
|
|
|
|
20180702:
|
|
On i386 and amd64 atomics are now inlined. Out of tree modules using
|
|
atomics will need to be rebuilt.
|
|
|
|
20180701:
|
|
The '%I' format in the kern.corefile sysctl limits the number of
|
|
core files that a process can generate to the number stored in the
|
|
debug.ncores sysctl. The '%I' format is replaced by the single digit
|
|
index. Previously, if all indexes were taken the kernel would overwrite
|
|
only a core file with the highest index in a filename.
|
|
Currently the system will create a new core file if there is a free
|
|
index or if all slots are taken it will overwrite the oldest one.
|
|
|
|
20180630:
|
|
Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
|
|
6.0.1. Please see the 20141231 entry below for information about
|
|
prerequisites and upgrading, if you are not already using clang 3.5.0
|
|
or higher.
|
|
|
|
20180628:
|
|
r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
|
|
needed to be changed to work with it. This change was made with r335763
|
|
and requires a mergemaster / etcupdate / etc to update the installed
|
|
file.
|
|
|
|
20180612:
|
|
r334930 changed the interface between the NFS modules, so they all
|
|
need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
|
|
|
|
20180530:
|
|
As of r334391 lld is the default amd64 system linker; it is installed
|
|
as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
|
|
longer necessary.
|
|
|
|
20180530:
|
|
The kernel / userland interface for devinfo changed, so you'll
|
|
need a new kernel and userland as a pair for it to work (rebuilding
|
|
lib/libdevinfo is all that's required). devinfo and devmatch will
|
|
not work, but everything else will when there's a mismatch.
|
|
|
|
20180523:
|
|
The on-disk format for hwpmc callchain records has changed to include
|
|
threadid corresponding to a given record. This changes the field offsets
|
|
and thus requires that libpmcstat be rebuilt before using a kernel
|
|
later than r334108.
|
|
|
|
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.
|
|
|
|
NOTE: As of r334391 lld is the default system linker on amd64, and no
|
|
workaround is necessary.
|
|
|
|
20180508:
|
|
The nxge(4) driver has been removed. This driver was for PCI-X 10g
|
|
cards made by s2io/Neterion. The company was acquired 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-existence 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 be loaded. Please report any problems to current@ and
|
|
imp@freebsd.org.
|
|
|
|
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.

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.

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 has 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 cheaper 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.

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. While an
|
|
installworld normally works by accident from multiuser after rebooting
|
|
the proper kernel, there are many cases where this will fail across this
|
|
upgrade and installworld from single user is required.
|
|
|
|
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.
|
|

|
|
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.

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.
|
|
|
|
20160708:
|
|
The stable/11 branch has been created from head@r302406.
|
|
|
|
After branch N is created, entries older than the N-2 branch point are removed
|
|
from this file. After stable/14 is branched and current becomes FreeBSD 15,
|
|
entries older than stable/12 branch point will be removed from current's
|
|
UPDATING file.

General Notes
|
|
-------------
|
|
Sometimes, obscure build problems are the result of environment
|
|
poisoning. This can happen because the make utility reads its
|
|
environment when searching for values for global variables. To run
|
|
your build attempts in an "environmental clean room", prefix all make
|
|
commands with 'env -i '. See the env(1) manual page for more details.
|
|
Occasionally a build failure will occur with "make -j" due to a race
|
|
condition. If this happens try building again without -j, and please
|
|
report a bug if it happens consistently.
|
|
|
|
When upgrading from one major version to another it is generally best to
|
|
upgrade to the latest code in the currently installed branch first, then
|
|
do an upgrade to the new branch. This is the best-tested upgrade path,
|
|
and has the highest probability of being successful. Please try this
|
|
approach if you encounter problems with a major version upgrade. Since
|
|
the stable 4.x branch point, one has generally been able to upgrade from
|
|
anywhere in the most recent stable branch to head / current (or even the
|
|
last couple of stable branches). See the top of this file when there's
|
|
an exception.
|
|
|
|
The update process will emit an error on an attempt to perform a build
|
|
or install from a FreeBSD version below the earliest supported version.
|
|
When updating from an older version the update should be performed one
|
|
major release at a time, including running `make delete-old` at each
|
|
step.
|
|
|
|
When upgrading a live system, having a root shell around before
|
|
installing anything can help undo problems. Not having a root shell
|
|
around can lead to problems if pam has changed too much from your
|
|
starting point to allow continued authentication after the upgrade.
|
|
|
|
This file should be read as a log of events. When a later event changes
|
|
information of a prior event, the prior event should not be deleted.
|
|
Instead, a pointer to the entry with the new information should be
|
|
placed in the old entry. Readers of this file should also sanity check
|
|
older entries before relying on them blindly. Authors of new entries
|
|
should write them with this in mind.
|
|
|
|
ZFS notes
|
|
---------
|
|
When upgrading the boot ZFS pool to a new version (via zpool upgrade),
|
|
always follow these three steps:
|
|
|
|
1) recompile and reinstall the ZFS boot loader and boot block
|
|
(this is part of "make buildworld" and "make installworld")
|
|
|
|
2) update the ZFS boot block on your boot drive (only required when
|
|
doing a zpool upgrade):
|
|
|
|
When booting on x86 via BIOS, use the following to update the ZFS boot
|
|
block on the freebsd-boot partition of a GPT partitioned drive ada0:
|
|
gpart bootcode -p /boot/gptzfsboot -i $N ada0
|
|
The value $N will typically be 1. For EFI booting, see EFI notes.
|
|
|
|
3) zpool upgrade the root pool. New bootblocks will work with old
|
|
pools, but not vice versa, so they need to be updated before any
|
|
zpool upgrade.
|
|
|
|
Non-boot pools do not need these updates.
|
|
|
|
EFI notes
|
|
---------
|
|
|
|
There are two locations the boot loader can be installed into. The
|
|
current location (and the default) is \efi\freebsd\loader.efi and using
|
|
efibootmgr(8) to configure it. The old location, that must be used on
|
|
deficient systems that don't honor efibootmgr(8) protocols, is the
|
|
fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy
|
|
/boot/loader.efi to this location, but on systems installed a long time
|
|
ago the ESP may be too small and /boot/boot1.efi may be needed unless
|
|
the ESP has been expanded in the meantime.
|
|
|
|
Recent systems will have the ESP mounted on /boot/efi, but older ones
|
|
may not have it mounted at all, or mounted in a different
|
|
location. Older arm SD images with MBR used /boot/msdos as the
|
|
mountpoint. The ESP is a MSDOS filesystem.
|
|
|
|
The EFI boot loader rarely needs to be updated. For ZFS booting,
|
|
however, you must update loader.efi before you do 'zpool upgrade' the
|
|
root zpool, otherwise the old loader.efi may reject the upgraded zpool
|
|
since it does not automatically understand some new features.
|
|
|
|
See loader.efi(8) and uefi(8) for more details.

|
To build a kernel
|
|
-----------------
|
|
If you are updating from a prior version of FreeBSD (even one just
|
|
a few days old), you should follow this procedure. It is the most
|
|
failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
|
|
|
|
make kernel-toolchain
|
|
make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
|
|
To test a kernel once
|
|
---------------------
|
|
If you just want to boot a kernel once (because you are not sure
|
|
if it works, or if you want to boot a known bad kernel to provide
|
|
debugging information) run
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
|
|
nextboot -k testkernel
|
|
|
|
To rebuild everything and install it on the current system.
|
|
-----------------------------------------------------------
|
|
# Note: sometimes if you are running current you gotta do more than
|
|
# is listed here if you are upgrading from a really old current.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
make buildworld
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
[1]
|
|
<reboot in single user> [3]
|
|
etcupdate -p [5]
|
|
make installworld
|
|
etcupdate -B [4]
|
|
make delete-old [6]
|
|
<reboot>
|
|
|
|
To cross-install current onto a separate partition
|
|
--------------------------------------------------
|
|
# In this approach we use a separate partition to hold
|
|
# current's root, 'usr', and 'var' directories. A partition
|
|
# holding "/", "/usr" and "/var" should be about 2GB in
|
|
# size.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<boot into -stable>
|
|
make buildworld
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
<maybe newfs current's root partition>
|
|
<mount current's root partition on directory ${CURRENT_ROOT}>
|
|
make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
|
|
make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
|
|
cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
|
|
<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
|
|
<reboot into current>
|
|
<do a "native" rebuild/install as described in the previous section>
|
|
<maybe install compatibility libraries from ports/misc/compat*>
|
|
<reboot>
|
|
|
|
|
|
To upgrade in-place from stable to current
|
|
----------------------------------------------
|
|
<make sure you have good level 0 dumps>
|
|
make buildworld [9]
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
[1]
|
|
<reboot in single user> [3]
|
|
etcupdate -p [5]
|
|
make installworld
|
|
etcupdate -B [4]
|
|
make delete-old [6]
|
|
<reboot>
|
|
|
|
Make sure that you've read the UPDATING file to understand the
|
|
tweaks to various things you need. At this point in the life
|
|
cycle of current, things change often and you are on your own
|
|
to cope. The defaults can also change, so please read ALL of
|
|
the UPDATING entries.
|
|
|
|
Also, if you are tracking -current, you must be subscribed to
|
|
freebsd-current@freebsd.org. Make sure that before you update
|
|
your sources that you have read and understood all the recent
|
|
messages there. If in doubt, please track -stable which has
|
|
much fewer pitfalls.
|
|
|
|
[1] If you have third party modules, such as vmware, you should disable
|
|
them at this point so they don't crash your system on
|
|
reboot. Alternatively, you should rebuild all the modules you have in
|
|
your system and install them as well. If you are running -current, you
|
|
should seriously consider placing all sources to all the modules for
|
|
your system (or symlinks to them) in /usr/local/sys/modules so this
|
|
happens automatically. If all your modules come from ports, then adding
|
|
the port origin directories to PORTS_MODULES instead is also automatic
|
|
and effective, eg:
|
|
PORTS_MODULES+=x11/nvidia-driver
|
|
|
|
[3] From the bootblocks, boot -s, and then do
|
|
fsck -p
|
|
mount -u /
|
|
mount -a
|
|
sh /etc/rc.d/zfs start # mount zfs filesystem, if needed
|
|
cd src # full path to source
|
|
adjkerntz -i # if CMOS is wall time
|
|
Also, when doing a major release upgrade, it is required that you boot
|
|
into single user mode to do the installworld.
|
|
|
|
[4] Note: This step is non-optional. Failure to do this step
|
|
can result in a significant reduction in the functionality of the
|
|
system. Attempting to do it by hand is not recommended and those
|
|
that pursue this avenue should read this file carefully, as well
|
|
as the archives of freebsd-current and freebsd-hackers mailing lists
|
|
for potential gotchas. See etcupdate(8) for more information.
|
|
|
|
[5] Usually this step is a no-op. However, from time to time
|
|
you may need to do this if you get unknown user in the following
|
|
step.
|
|
|
|
[6] This only deletes old files and directories. Old libraries
|
|
can be deleted by "make delete-old-libs", but you have to make
|
|
sure that no program is using those libraries anymore.
|
|
|
|
[8] The new kernel must be able to run existing binaries used by an
|
|
installworld. When upgrading across major versions, the new kernel's
|
|
configuration must include the correct COMPAT_FREEBSD<n> option for
|
|
existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure
|
|
to do so may leave you with a system that is hard to boot to recover. A
|
|
GENERIC kernel will include suitable compatibility options to run
|
|
binaries from older branches. Note that the ability to run binaries
|
|
from unsupported branches is not guaranteed.
|
|
|
|
Make sure that you merge any new devices from GENERIC since the
|
|
last time you updated your kernel config file. Options also
|
|
change over time, so you may need to adjust your custom kernels
|
|
for these as well.
|
|
|
|
[9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
|
|
"?=" instead of the "=" assignment operator, so that buildworld can
|
|
override the CPUTYPE if it needs to.
|
|
|
|
MAKEOBJDIRPREFIX must be defined in an environment variable, and
|
|
not on the command line, or in /etc/make.conf. buildworld will
|
|
warn if it is improperly defined.
|
|
FORMAT:
|
|
|
|
This file contains a list, in reverse chronological order, of major
|
|
breakages in tracking -current. It is not guaranteed to be a complete
|
|
list of such breakages, and only contains entries since September 23, 2011.
|
|
If you need to see UPDATING entries from before that date, you will need
|
|
to fetch an UPDATING file from an older FreeBSD release.
