and/or ports.

NOTE TO PEOPLE WHO THINK THAT FreeBSD 15.x IS SLOW:

FreeBSD 15.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".)

20250214:

Commit 4517fbfd4251 modified the internal API between the

nfscommon and nfscl modules. As such, both of these modules

need to be rebuilt from sources.

20250201:

The NFS related daemons, that provide RPC services to the kernel:

gssd(8), rpcbind(8), rpc.tlsservd(8) and rpc.tlsclntd(8), now use a

different transport - netlink(4) socket instead of unix(4). Users of

NFS need to upgrade both kernel and world (binaries and libc) at once.

Also, any revision between 88cd1e17a7d8 and 99e5a70046da should be

avoided.

20250129:

Defer the January 19, 2038 date limit in UFS1 filesystems to

February 7, 2106. This affects only UFS1 format filesystems.

See commit message 1111a44301da for details.

20250127:

The Allwinner a10_timer driver has been renamed to aw_driver. If you

have a custom kernel configuration including the line 'device

a10_timer', it must be adjusted to 'device aw_timer'. The same applies

for device exclusions with 'nodevice'.

20250106:

A new SOC_ROCKCHIP options appeared, so if you have a custom kernel configuration

targetting Rockchip SoC you need to add it so shared and mandatory drivers for

this SoC familly will be selected.

Also a new rk8xx device was added, this select the base driver for Rockchip PMIC.

20241223:

The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs

file systems has changed. An NFS server that exports any of these file

systems will need its clients to unmount and remount the exports.

20241216:

The iwm(4) firmwares are no longer compiled as kernel modules but instead

shipped as raw files. For pkgbase users if you use iwm(4) you will need

to install the FreeBSD-firmware-iwm package.

20241124:

The OpenBSD derived bc and dc implementations and the WITHOUT_GH_BC

option that allowed building them instead of the advanced version

imported more than 4 years ago have been removed.

20241025:

The support for the rc_fast_and_loose variable has been removed from

rc.subr(8). Users setting rc_fast_and_loose on their systems are

advised to make sure their customizations to rc service scripts

do not depend on having a single shell environment shared across

all the rc service scripts during booting and shutdown.

20241013:

The ciss driver was updated to cope better with hotplug events that

caused it to panic before, and to support more than 48 drives attached

to the card. These changes were made w/o benefit of hardware for testing

and ciss(4) users should be on the lookout for regressions.

20240729:

The build now defaults to WITHOUT_CLEAN - i.e., no automatic clean

is performed at the beginning of buildworld or buildkernel. The

WITH_CLEAN src.conf(5) knob can be used to restore the previous

behaviour.

If you encounter incremental build issues, please report them to the

freebsd-current mailing list so that a special-case dependency can be

added, if necessary.

20240715:

We now lean more heavily on ACPI enumeration for some traditional

devices. uart has moved from isa to acpi so the hints act as wiring

instead of device enumeration. Hints for parallel port, floppy, etc

have been removed. Before upgrading, grep your dmesg for lines like:

uart1: non-PNP ISA device will be removed from GENERIC in FreeBSD 15.

to see if you need to start including hints for the device on isa

in your loader.conf or device.hints file. APU1 (but not APU2) boards

are known to be affected, but there may be others.

20240712:

Support for armv6 has been disconnected and is being removed.

20240617:

ifconfig now treats IPv4 addresses without a width or mask as an error.

Specify the desired mask or width along with the IP address on the

ifconfig command line and in rc.conf.

20240428:

OpenBSM auditing runtime (auditd, etc.) has been moved into the new

package FreeBSD-audit. If you use OpenBSM auditing and pkgbase, you

should install FreeBSD-audit.

20240424:

cron, lpr, and ntpd have been moved from FreeBSD-utilities into their

own packages. If you use pkgbase, you should install the relevant

packages: FreeBSD-cron, FreeBSD-lp, or FreeBSD-ntp.

20240406:

Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have

been upgraded to 18.1.6. It is important that you run `make delete-old`

as described in the COMMON ITEMS section, otherwise several libc++

headers that are obsolete and need to be removed can cause compilation

errors in C++ programs.

20240205:

For dynamically linked programs, system calls are now made from

libsys rather than libc. No change in linkage is required as

libsys is an auxiliary filter for libc. People building custom

images must ensure that libsys.so.7 is included.

20240202:

Loader now also read configuration files listed in local_loader_conf_files.

Files listed here are the last ones read. And /boot/loader.conf.local was

moved from loader_conf_files to local_loader_conf_files leaving only

loader.conf and device.hints in loader_conf_files by default.

The following sequencing is applied:

1. Bootstrap:

/boot/defaults/loader.conf

2. Read loader_conf_files files:

/boot/device.hints

/boot/loader.conf

3. Read loader_conf_dirs files:

/boot/loader.conf.d/*.conf

4. And finally, rread local_loader_conf_files files:

/boot/loader.conf.local

20240201:

sendmail 8.18.1 has been imported and merged. This version enforces

stricter RFC compliance by default, especially with respect to line

endings. This may cause issues with receiving messages from

non-compliant MTAs; please see the first 8.18.1 release note in

contrib/sendmail/RELEASE_NOTES for mitigations.

20240111:

Commit cc760de2183f changed the internal interface between

the nfscommon and nfscl modules. As such, both need to be

rebuilt from sources. Therefore, __FreeBSD_version was

bumped to 1500010.

20231120:

If you have an arm64 system that uses ACPI, you will need to update your

loader.efi in the ESP when you update past this point. Detection of ACPI

was moved earlier in the binary so the scripts could use it, but old

binaries don't have this, so we default to 'no ACPI' in this case. You can

undisable ACPI by doing

OK unset hint.acpi.0.disabled

This can also be used to recover any other system that was updated in the

small window where amd64 was also broken.

20231113:

The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled

it is always installed as /usr/bin/ld.

20231027:

Forward compatibility (running the new code on old kernels) for the

"ino64" project have been removed. The need for it has passed long ago.

20231018:

Commit 57ce37f9dcd0 changed the internal KAPI between the

nfscommon and nfscl modules. Both must be rebuilt from sources.

20231010:

dialog(1) has been replaced in base by bsddialog(1), while most of the

time replacing a dialog(1) call by a bsddialog(1) call works out of the

box, bsddialog(1) is not considered as a drop-in replacement for

dialog(1).

If you do depend on dialog(1) functionality, please install cdialog

from ports:

pkg install cdialog

20230927:

The EARLY_AP_STARTUP kernel option is mandatory on x86. The option

has been added to DEFAULTS, so it should automatically be included in

custom kernel configurations without any additional change.

20230922:

A new loader tunable net.pf.default_to_drop allows pf(4)’s default

behaviour to be changed from pass to drop. Previously this required

recompiling the kernel with the option PF_DEFAULT_TO_DROP.

20230914:

Enable splitting out pkgbase manpages into separate packages by

default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf.

20230911:

Move standard include files to the clibs-dev package and move clang

internal libraries and headers to clang and clang-dev. Upgrading systems

installed using pkgbase past this change involves extra steps to allow

for these file moves:

pkg upgrade -y FreeBSD-utilities

pkg upgrade -y FreeBSD-utilities-dev

pkg upgrade -y

20230909:

Enable vnet sysctl variables to be loader tunable. SYSCTLs which

belongs to VNETs can be initialized during early boot or module

loading if they are marked with CTLFLAG_TUN and there are

corresponding kernel environment variables.

20230901:

The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have

been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively.

20230824:

FreeBSD 15.0-CURRENT.

20230817:

Serial communication (in boot loaders, kernel, and userland) has

been changed to default to 115200 bps, in line with common industry

practice and typcial firmware serial console redirection

configuration.

Note that the early x86 BIOS bootloader (i.e., boot0sio) does not

support rates above 9600 bps and is not changed. boot0sio users may

set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot

components, or use the standard boot0 and have the boot2 stage start

with the serial port at 115200.

20230807:

Following the general removal of MIPS support, the ath(4) AHB bus-

frontend has been removed, too, and building of the PCI support is

integrated with the ath(4) main module again. As a result, there's

no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or

"device ath_pci" in the kernel configuration.

20230803:

MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config.

Out-of-tree kernel modules will need to be rebuilt.

20230724:

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.

20230713:

stable/14 branch created.

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.

20221002:

OPIE has been removed from the base system. If needed, it can

be installed from ports (security/opie) or packages (opie).

Otherwise, make sure that your PAM policies do not reference

pam_opie or pam_opieaccess.

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.

20210121:

stable/13 branch created.

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
