COMMON ITEMS: section later in the file. These instructions assume that you
|
|
basically know what you are doing. If not, then please consult the FreeBSD
|
|
handbook:

|
|
|
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html

|
Items affecting the ports and packages system can be found in
|
|
/usr/ports/UPDATING. Please read that file before running portupgrade.
|
|
|
|
NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
|
|
from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to
|
|
the tip of head, and then rebuild without this option. The bootstrap process
|
|
from older version of current across the gcc/clang cutover is a bit fragile.
|
|
|
|
NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW:
|
|
FreeBSD 13.x has many debugging features turned on, in both the kernel
|
|
and userland. These features attempt to detect incorrect use of
|
|
system primitives, and encourage loud failure through extra sanity
|
|
checking and fail stop semantics. They also substantially impact
|
|
system performance. If you want to do performance measurement,
|
|
benchmarking, and optimization, you'll want to turn them off. This
|
|
includes various WITNESS- related kernel options, INVARIANTS, malloc
|
|
debugging flags in userland, and various verbose features in the
|
|
kernel. Many developers choose to disable these features on build
|
|
machines to maximize performance. (To completely disable malloc
|
|
debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
|
|
disable the most expensive debugging functionality run
|
|
"ln -s 'abort:false,junk:false' /etc/malloc.conf".)

|
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 port#s 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 deamons 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 througout 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 frambuffer 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 framebuffer are that
|
|
u-boot will expose as an EFI framebuffer.
|
|
|
|
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 aquired by Exar and
|
|
no longer sells or supports Ethernet products. If you have device
|
|
nxge in your kernel config file it must be removed.
|
|
|
|
20180504:
|
|
The tz database (tzdb) has been updated to 2018e. This version more
|
|
correctly models time stamps in time zones with negative DST such as
|
|
Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
|
|
Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
|
|
time zone abbreviations and the tm_isdst flag.
|
|
|
|
20180502:
|
|
The ixgb(4) driver has been removed. This driver was for an early and
|
|
uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
|
|
quickly shifted to the long lived ixgbe family. If you have device
|
|
ixgb in your kernel config file it must be removed.
|
|
|
|
20180501:
|
|
The lmc(4) driver has been removed. This was a WAN interface
|
|
card that was already reportedly rare in 2003, and had an ambiguous
|
|
license. If you have device lmc in your kernel config file it must
|
|
be removed.
|
|
|
|
20180413:
|
|
Support for Arcnet networks has been removed. If you have device
|
|
arcnet or device cm in your kernel config file they must be
|
|
removed.
|
|
|
|
20180411:
|
|
Support for FDDI networks has been removed. If you have device
|
|
fddi or device fpa in your kernel config file they must be
|
|
removed.
|
|
|
|
20180406:
|
|
In addition to supporting RFC 3164 formatted messages, the
|
|
syslogd(8) service is now capable of parsing RFC 5424 formatted
|
|
log messages. The main benefit of using RFC 5424 is that clients
|
|
may now send log messages with timestamps containing year numbers,
|
|
microseconds and time zone offsets.
|
|
|
|
Similarly, the syslog(3) C library function has been altered to
|
|
send RFC 5424 formatted messages to the local system logging
|
|
daemon. On systems using syslogd(8), this change should have no
|
|
negative impact, as long as syslogd(8) and the C library are
|
|
updated at the same time. On systems using a different system
|
|
logging daemon, it may be necessary to make configuration
|
|
adjustments, depending on the software used.
|
|
|
|
When using syslog-ng, add the 'syslog-protocol' flag to local
|
|
input sources to enable parsing of RFC 5424 formatted messages:
|
|
|
|
source src {
|
|
unix-dgram("/var/run/log" flags(syslog-protocol));
|
|
}
|
|
|
|
When using rsyslog, disable the 'SysSock.UseSpecialParser' option
|
|
of the 'imuxsock' module to let messages be processed by the
|
|
regular RFC 3164/5424 parsing pipeline:
|
|
|
|
module(load="imuxsock" SysSock.UseSpecialParser="off")
|
|
|
|
Do note that these changes only affect communication between local
|
|
applications and syslogd(8). The format that syslogd(8) uses to
|
|
store messages on disk or forward messages to other systems
|
|
remains unchanged. syslogd(8) still uses RFC 3164 for these
|
|
purposes. Options to customize this behaviour will be added in the
|
|
future. Utilities that process log files stored in /var/log are
|
|
thus expected to continue to function as before.
|
|
|
|
__FreeBSD_version has been incremented to 1200061 to denote this
|
|
change.
|
|
|
|
20180328:
|
|
Support for token ring networks has been removed. If you
|
|
have "device token" in your kernel config you should remove
|
|
it. No device drivers supported token ring.
|
|
|
|
20180323:
|
|
makefs was modified to be able to tag ISO9660 El Torito boot catalog
|
|
entries as EFI instead of overloading the i386 tag as done previously.
|
|
The amd64 mkisoimages.sh script used to build amd64 ISO images for
|
|
release was updated to use this. This may mean that makefs must be
|
|
updated before "make cdrom" can be run in the release directory. This
|
|
should be as simple as:
|
|
|
|
$ cd $SRCDIR/usr.sbin/makefs
|
|
$ make depend all install
|
|
|
|
20180212:
|
|
FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
|
|
now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
|
|
Co-existance for the transition period will come shortly. Booting is a
|
|
complex environment and test coverage for Lua-enabled loaders has been
|
|
thin, so it would be prudent to assume it might not work and make
|
|
provisions for backup boot methods.
|
|
|
|
20180211:
|
|
devmatch functionality has been turned on in devd. It will automatically
|
|
load drivers for unattached devices. This may cause unexpected drivers to
|
|
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.
|
|
|
|
20180110:
|
|
LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
|
|
This means it is used to link the kernel and userland libraries and
|
|
executables, but is not yet installed as /usr/bin/ld by default.
|
|
|
|
To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
|
|
WITHOUT_LLD_BOOTSTRAP=yes
|
|
|
|
20180110:
|
|
On i386, pmtimer has been removed. Its functionality has been folded
|
|
into apm. It was a no-op on ACPI in current for a while now (but was still
|
|
needed on i386 in FreeBSD 11 and earlier). Users may need to remove it
|
|
from kernel config files.
|
|
|
|
20180104:
|
|
The use of RSS hash from the network card aka flowid has been
|
|
disabled by default for lagg(4) as it's currently incompatible with
|
|
the lacp and loadbalance protocols.
|
|
|
|
This can be re-enabled by setting the following in loader.conf:
|
|
net.link.lagg.default_use_flowid="1"
|
|
|
|
20180102:
|
|
The SW_WATCHDOG option is no longer necessary to enable the
|
|
hardclock-based software watchdog if no hardware watchdog is
|
|
configured. As before, SW_WATCHDOG will cause the software
|
|
watchdog to be enabled even if a hardware watchdog is configured.

r326887 fixes the issue described in the 20171214 UPDATING entry.
|
|
r326888 flips the switch back to building GELI support always.
|
|
|
|
20171214:
|
|
r362593 broke ZFS + GELI support for reasons unknown. However,
|
|
it also broke ZFS support generally, so GELI has been turned off
|
|
by default as the lesser evil in r326857. If you boot off ZFS and/or
|
|
GELI, it might not be a good time to update.
|
|
|
|
20171125:
|
|
PowerPC users must update loader(8) by rebuilding world before
|
|
installing a new kernel, as the protocol connecting them has
|
|
changed. Without the update, loader metadata will not be passed
|
|
successfully to the kernel and users will have to enter their
|
|
root partition at the kernel mountroot prompt to continue booting.
|
|
Newer versions of loader can boot old kernels without issue.
|
|
|
|
20171110:
|
|
The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
|
|
WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
|
|
to WITH/OUT_LOADER_GELI.
|
|
|
|
20171106:
|
|
The naive and non-compliant support of posix_fallocate(2) in ZFS
|
|
has been removed as of r325320. The system call now returns EINVAL
|
|
when used on a ZFS file. Although the new behavior complies with the
|
|
standard, some consumers are not prepared to cope with it.
|
|
One known victim is lld prior to r325420.
|
|
|
|
20171102:
|
|
Building in a FreeBSD src checkout will automatically create object
|
|
directories now rather than store files in the current directory if
|
|
'make obj' was not ran. Calling 'make obj' is no longer necessary.
|
|
This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
|
|
/etc/src-env.conf (not /etc/src.conf), or passing the option in the
|
|
environment.
|
|
|
|
20171101:
|
|
The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
|
|
builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
|
|
/usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
|
|
format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
|
|
the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
|
|
The UNIFIED_OBJDIR option is a transitional feature that will be
|
|
removed for 12.0 release; please migrate to the new format for any
|
|
tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
|
|
than hardcoding paths.
|
|
|
|
20171028:
|
|
The native-xtools target no longer installs the files by default to the
|
|
OBJDIR. Use the native-xtools-install target with a DESTDIR to install
|
|
to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
|
|
|
|
20171021:
|
|
As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
|
|
options are changing from controlling the build if defined / undefined
|
|
to controlling the build with explicit 'yes' or 'no' values. They will
|
|
shift to WITH/WITHOUT options to match other options in the system.
|
|
|
|
20171010:
|
|
libstand has turned into a private library for sys/boot use only.
|
|
It is no longer supported as a public interface outside of sys/boot.
|
|
|
|
20171005:
|
|
The arm port has split armv6 into armv6 and armv7. armv7 is now
|
|
a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
|
|
and are running a kernel from before r324363, you will need to add
|
|
MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
|
|
|
|
20171003:
|
|
When building multiple kernels using KERNCONF, non-existent KERNCONF
|
|
files will produce an error and buildkernel will fail. Previously
|
|
missing KERNCONF files silently failed giving no indication as to
|
|
why, only to subsequently discover during installkernel that the
|
|
desired kernel was never built in the first place.
|
|
|
|
20170912:
|
|
The default serial number format for CTL LUNs has changed. This will
|
|
affect users who use /dev/diskid/* device nodes, or whose FibreChannel
|
|
or iSCSI clients care about their LUNs' serial numbers. Users who
|
|
require serial number stability should hardcode serial numbers in
|
|
/etc/ctl.conf .
|
|
|
|
20170912:
|
|
For 32-bit arm compiled for hard-float support, soft-floating point
|
|
binaries now always get their shared libraries from
|
|
LD_SOFT_LIBRARY_PATH (in the past, this was only used if
|
|
/usr/libsoft also existed). Only users with a hard-float ld.so, but
|
|
soft-float everything else should be affected.
|
|
|
|
20170826:
|
|
The geli password typed at boot is now hidden. To restore the previous
|
|
behavior, see geli(8) for configuration options.
|
|
|
|
20170825:
|
|
Move PMTUD blackhole counters to TCPSTATS and remove them from bare
|
|
sysctl values. Minor nit, but requires a rebuild of both world/kernel
|
|
to complete.
|
|
|
|
20170814:
|
|
"make check" behavior (made in ^/head@r295380) has been changed to
|
|
execute from a limited sandbox, as opposed to executing from
|
|
${TESTSDIR}.
|
|
|
|
Behavioral changes:
|
|
- The "beforecheck" and "aftercheck" targets are now specified.
|
|
- ${CHECKDIR} (added in commit noted above) has been removed.
|
|
- Legacy behavior can be enabled by setting
|
|
WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
|
|
|
|
If the limited sandbox mode is enabled, "make check" will execute
|
|
"make distribution", then install, execute the tests, and clean up the
|
|
sandbox if successful.
|
|
|
|
The "make distribution" and "make install" targets are typically run as
|
|
root to set appropriate permissions and ownership at installation time.
|
|
The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
|
|
environment if executing "make check" with limited sandbox mode using
|
|
an unprivileged user.
|
|
|
|
20170808:
|
|
Since the switch to GPT disk labels, fsck for UFS/FFS has been
|
|
unable to automatically find alternate superblocks. As of r322297,
|
|
the information needed to find alternate superblocks has been
|
|
moved to the end of the area reserved for the boot block.
|
|
Filesystems created with a newfs of this vintage or later
|
|
will create the recovery information. If you have a filesystem
|
|
created prior to this change and wish to have a recovery block
|
|
created for your filesystem, you can do so by running fsck in
|
|
foreground mode (i.e., do not use the -p or -y options). As it
|
|
starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
|
|
to which you should answer yes.
|
|
|
|
20170728:
|
|
As of r321665, an NFSv4 server configuration that services
|
|
Kerberos mounts or clients that do not support the uid/gid in
|
|
owner/owner_group string capability, must explicitly enable
|
|
the nfsuserd daemon by adding nfsuserd_enable="YES" to the
|
|
machine's /etc/rc.conf file.
|
|
|
|
20170722:
|
|
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
|
|
Please see the 20141231 entry below for information about prerequisites
|
|
and upgrading, if you are not already using clang 3.5.0 or higher.
|
|
|
|
20170701:
|
|
WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
|
|
r-commands (rlogin, rsh, etc.) to be built with the base system.
|
|
|
|
20170625:
|
|
The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
|
|
a very major ABI incompatible change, so users of FreeBSD/powerpc must
|
|
be careful when performing source upgrades. It is best to run
|
|
'make installworld' from an alternate root system, either a live
|
|
CD/memory stick, or a temporary root partition. Additionally, all ports
|
|
must be recompiled. powerpc64 is largely unaffected, except in the case
|
|
of 32-bit compatibility. All 32-bit binaries will be affected.
|
|
|
|
20170623:
|
|
Forward compatibility for the "ino64" project have been committed. This
|
|
will allow most new binaries to run on older kernels in a limited
|
|
fashion. This prevents many of the common foot-shooting actions in the
|
|
upgrade as well as the limited ability to roll back the kernel across
|
|
the ino64 upgrade. Complicated use cases may not work properly, though
|
|
enough simpler ones work to allow recovery in most situations.
|
|
|
|
20170620:
|
|
Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
|
|
if you require the GPL compiler.
|
|
|
|
20170618:
|
|
The internal ABI used for communication between the NFS kernel modules
|
|
was changed by r320085, so __FreeBSD_version was bumped to
|
|
ensure all the NFS related modules are updated together.
|
|
|
|
20170617:
|
|
The ABI of struct event was changed by extending the data
|
|
member to 64bit and adding ext fields. For upgrade, same
|
|
precautions as for the entry 20170523 "ino64" must be
|
|
followed.
|
|
|
|
20170531:
|
|
The GNU roff toolchain has been removed from base. To render manpages
|
|
which are not supported by mandoc(1), man(1) can fallback on GNU roff
|
|
from ports (and recommends to install it).
|
|
To render roff(7) documents, consider using GNU roff from ports or the
|
|
heirloom doctools roff toolchain from ports via pkg install groff or
|
|
via pkg install heirloom-doctools.
|
|
|
|
20170524:
|
|
The ath(4) and ath_hal(4) modules now build piecemeal to allow for
|
|
smaller runtime footprint builds. This is useful for embedded systems
|
|
which only require one chipset support.
|
|
|
|
If you load it as a module, make sure this is in /boot/loader.conf:
|
|
|
|
if_ath_load="YES"
|
|
|
|
This will load the HAL, all chip/RF backends and if_ath_pci.
|
|
If you have if_ath_pci in /boot/loader.conf, ensure it is after
|
|
if_ath or it will not load any HAL chipset support.
|
|
|
|
If you want to selectively load things (eg on ye cheape ARM/MIPS
|
|
platforms where RAM is at a premium) you should:
|
|
|
|
* load ath_hal
|
|
* load the chip modules in question
|
|
* load ath_rate, ath_dfs
|
|
* load ath_main
|
|
* load if_ath_pci and/or if_ath_ahb depending upon your particular
|
|
bus bind type - this is where probe/attach is done.

20170523:
|
|
The "ino64" 64-bit inode project has been committed, which extends
|
|
a number of types to 64 bits. Upgrading in place requires care and
|
|
adherence to the documented upgrade procedure.
|
|
|
|
If using a custom kernel configuration ensure that the
|
|
COMPAT_FREEBSD11 option is included (as during the upgrade the
|
|
system will be running the ino64 kernel with the existing world).
|
|
|
|
For the safest in-place upgrade begin by removing previous build
|
|
artifacts via "rm -rf /usr/obj/*". Then, carefully follow the
|
|
full procedure documented below under the heading "To rebuild
|
|
everything and install it on the current system." Specifically,
|
|
a reboot is required after installing the new kernel before
|
|
installing world.
|
|
|
|
20170424:
|
|
The NATM framework including the en(4), fatm(4), hatm(4), and
|
|
patm(4) devices has been removed. Consumers should plan a
|
|
migration before the end-of-life date for FreeBSD 11.
|
|
|
|
20170420:
|
|
GNU diff has been replaced by a BSD licensed diff. Some features of GNU
|
|
diff has not been implemented, if those are needed a newer version of
|
|
GNU diff is available via the diffutils package under the gdiff name.
|
|
|
|
20170413:
|
|
As of r316810 for ipfilter, keep frags is no longer assumed when
|
|
keep state is specified in a rule. r316810 aligns ipfilter with
|
|
documentation in man pages separating keep frags from keep state.
|
|
This allows keep state to be specified without forcing keep frags
|
|
and allows keep frags to be specified independently of keep state.
|
|
To maintain previous behaviour, also specify keep frags with
|
|
keep state (as documented in ipf.conf.5).
|
|
|
|
20170407:
|
|
arm64 builds now use the base system LLD 4.0.0 linker by default,
|
|
instead of requiring that the aarch64-binutils port or package be
|
|
installed. To continue using aarch64-binutils, set
|
|
CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
|
|
|
|
20170405:
|
|
The UDP optimization in entry 20160818 that added the sysctl
|
|
net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
|
|
packets will no longer be treated as L3 broadcast packets.
|
|
|
|
20170331:
|
|
Binds and sends to the loopback addresses, IPv6 and IPv4, will now
|
|
use any explicitly assigned loopback address available in the jail
|
|
instead of using the first assigned address of the jail.
|
|
|
|
20170329:
|
|
The ctl.ko module no longer implements the iSCSI target frontend:
|
|
cfiscsi.ko does instead.
|
|
|
|
If building cfiscsi.ko as a kernel module, the module can be loaded
|
|
via one of the following methods:
|
|
- `cfiscsi_load="YES"` in loader.conf(5).
|
|
- Add `cfiscsi` to `$kld_list` in rc.conf(5).
|
|
- ctladm(8)/ctld(8), when compiled with iSCSI support
|
|
(`WITH_ISCSI=yes` in src.conf(5))
|
|
|
|
Please see cfiscsi(4) for more details.
|
|
|
|
20170316:
|
|
The mmcsd.ko module now additionally depends on geom_flashmap.ko.
|
|
Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
|
|
same source (previously, the dependency of mmcsd.ko on mmc.ko was
|
|
missing, but mmcsd.ko now will refuse to load if it is incompatible
|
|
with mmc.ko).
|
|
|
|
20170315:
|
|
The syntax of ipfw(8) named states was changed to avoid ambiguity.
|
|
If you have used named states in the firewall rules, you need to modify
|
|
them after installworld and before rebooting. Now named states must
|
|
be prefixed with colon.
|
|
|
|
20170311:
|
|
The old drm (sys/dev/drm/) drivers for i915 and radeon have been
|
|
removed as the userland we provide cannot use them. The KMS version
|
|
(sys/dev/drm2) supports the same hardware.
|
|
|
|
20170302:
|
|
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
|
|
Please see the 20141231 entry below for information about prerequisites
|
|
and upgrading, if you are not already using clang 3.5.0 or higher.
|
|
|
|
20170221:
|
|
The code that provides support for ZFS .zfs/ directory functionality
|
|
has been reimplemented. It's not possible now to create a snapshot
|
|
by mkdir under .zfs/snapshot/. That should be the only user visible
|
|
change.
|
|
|
|
20170216:
|
|
EISA bus support has been removed. The WITH_EISA option is no longer
|
|
valid.
|
|
|
|
20170215:
|
|
MCA bus support has been removed.
|
|
|
|
20170127:
|
|
The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
|
|
WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
|
|
|
|
20170112:
|
|
The EM_MULTIQUEUE kernel configuration option is deprecated now that
|
|
the em(4) driver conforms to iflib specifications.
|
|
|
|
20170109:
|
|
The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
|
|
IFLIB. If you have a custom kernel configuration that excludes em(4)
|
|
but you use igb(4), you need to re-add em(4) to your custom configuration.
|
|
|
|
20161217:

20161119:
|
|
The layout of the pmap structure has changed for powerpc to put the pmap
|
|
statistics at the front for all CPU variations. libkvm(3) and all tools
|
|
that link against it need to be recompiled.
|
|
|
|
20161030:
|
|
isl(4) and cyapa(4) drivers now require a new driver,
|
|
chromebook_platform(4), to work properly on Chromebook-class hardware.
|
|
On other types of hardware the drivers may need to be configured using
|
|
device hints. Please see the corresponding manual pages for details.
|
|
|
|
20161017:
|
|
The urtwn(4) driver was merged into rtwn(4) and now consists of
|
|
rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
|
|
parts.
|
|
Also, firmware for RTL8188CE was renamed due to possible name
|
|
conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
|
|
|
|
20161015:
|
|
GNU rcs has been removed from base. It is available as packages:
|
|
- rcs: Latest GPLv3 GNU rcs version.
|
|
- rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
|
|
removed from base.
|
|
|
|
20161008:
|
|
Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
|
|
modules now requires that the kernel configuration contain the
|
|
TCP_HHOOK option. (This option is included in the GENERIC kernel.)
|
|
|
|
20161003:
|
|
The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
|
|
ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
|
|
|
|
20160924:
|
|
Relocatable object files with the extension of .So have been renamed
|
|
to use an extension of .pico instead. The purpose of this change is
|
|
to avoid a name clash with shared libraries on case-insensitive file
|
|
systems. On those file systems, foo.So is the same file as foo.so.
|
|
|
|
20160918:
|
|
GNU rcs has been turned off by default. It can (temporarily) be built
|
|
again by adding WITH_RCS knob in src.conf.
|
|
Otherwise, GNU rcs is available from packages:
|
|
- rcs: Latest GPLv3 GNU rcs version.
|
|
- rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
|
|
|
|
20160918:
|
|
The backup_uses_rcs functionality has been removed from rc.subr.
|
|

|
|
The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
|
|
two separate components, QUEUE_MACRO_DEBUG_TRACE and
|
|
QUEUE_MACRO_DEBUG_TRASH. Define both for the original
|
|
QUEUE_MACRO_DEBUG behavior.
|
|
|
|
20160824:
|
|
r304787 changed some ioctl interfaces between the iSCSI userspace
|
|
programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
|
|
rebuilt to work with new kernels. __FreeBSD_version has been bumped
|
|
to 1200005.
|
|
|
|
20160818:
|
|
The UDP receive code has been updated to only treat incoming UDP
|
|
packets that were addressed to an L2 broadcast address as L3
|
|
broadcast packets. It is not expected that this will affect any
|
|
standards-conforming UDP application. The new behaviour can be
|
|
disabled by setting the sysctl net.inet.udp.require_l2_bcast to
|
|
0.
|
|
|
|
20160818:
|
|
Remove the openbsd_poll system call.
|
|
__FreeBSD_version has been bumped because of this.
|
|
|
|
20160708:
|
|
The stable/11 branch has been created from head@r302406.
|
|
|
|
20160622:
|
|
The libc stub for the pipe(2) system call has been replaced with
|
|
a wrapper that calls the pipe2(2) system call and the pipe(2)
|
|
system call is now only implemented by the kernels that include
|
|
"options COMPAT_FREEBSD10" in their config file (this is the
|
|
default). Users should ensure that this option is enabled in
|
|
their kernel or upgrade userspace to r302092 before upgrading their
|
|
kernel.
|
|
|
|
20160527:
|
|
CAM will now strip leading spaces from SCSI disks' serial numbers.
|
|
This will affect users who create UFS filesystems on SCSI disks using
|
|
those disk's diskid device nodes. For example, if /etc/fstab
|
|
previously contained a line like
|
|
"/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
|
|
change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
|
|
transforms like gmirror may also be affected. ZFS users should
|
|
generally be fine.
|
|
|
|
20160523:
|
|
The bitstring(3) API has been updated with new functionality and
|
|
improved performance. But it is binary-incompatible with the old API.
|
|
Objects built with the new headers may not be linked against objects
|
|
built with the old headers.
|
|
|
|
20160520:
|
|
The brk and sbrk functions have been removed from libc on arm64.
|
|
Binutils from ports has been updated to not link to these
|
|
functions and should be updated to the latest version before
|
|
installing a new libc.
|
|
|
|
20160517:
|
|
The armv6 port now defaults to hard float ABI. Limited support
|
|
for running both hardfloat and soft float on the same system
|
|
is available using the libraries installed with -DWITH_LIBSOFT.
|
|
This has only been tested as an upgrade path for installworld
|
|
and packages may fail or need manual intervention to run. New
|
|
packages will be needed.
|
|
|
|
To update an existing self-hosted armv6hf system, you must add
|
|
TARGET_ARCH=armv6 on the make command line for both the build
|
|
and the install steps.
|
|
|
|
20160510:
|
|
Kernel modules compiled outside of a kernel build now default to
|
|
installing to /boot/modules instead of /boot/kernel. Many kernel
|
|
modules built this way (such as those in ports) already overrode
|
|
KMODDIR explicitly to install into /boot/modules. However,
|
|
manually building and installing a module from /sys/modules will
|
|
now install to /boot/modules instead of /boot/kernel.
|
|
|
|
20160414:
|
|
The CAM I/O scheduler has been committed to the kernel. There should be
|
|
no user visible impact. This does enable NCQ Trim on ada SSDs. While the
|
|
list of known rogues that claim support for this but actually corrupt
|
|
data is believed to be complete, be on the lookout for data
|
|
corruption. The known rogue list is believed to be complete:
|
|
|
|
o Crucial MX100, M550 drives with MU01 firmware.
|
|
o Micron M510 and M550 drives with MU01 firmware.
|
|
o Micron M500 prior to MU07 firmware
|
|
o Samsung 830, 840, and 850 all firmwares
|
|
o FCCT M500 all firmwares
|
|
|
|
Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
|
|
with working NCQ TRIM. For Micron branded drives, see your sales rep for
|
|
updated firmware. Black listed drives will work correctly because these
|
|
drives work correctly so long as no NCQ TRIMs are sent to them. Given
|
|
this list is the same as found in Linux, it's believed there are no
|
|
other rogues in the market place. All other models from the above
|
|
vendors work.
|
|
|
|
To be safe, if you are at all concerned, you can quirk each of your
|
|
drives to prevent NCQ from being sent by setting:
|
|
kern.cam.ada.X.quirks="0x2"
|
|
in loader.conf. If the drive requires the 4k sector quirk, set the
|
|
quirks entry to 0x3.
|
|
|
|
20160330:
|
|
The FAST_DEPEND build option has been removed and its functionality is
|
|
now the one true way. The old mkdep(1) style of 'make depend' has
|
|
been removed. See 20160311 for further details.
|
|
|
|
20160317:
|
|
Resource range types have grown from unsigned long to uintmax_t. All
|
|
drivers, and anything using libdevinfo, need to be recompiled.
|
|
|
|
20160311:
|
|
WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
|
|
builds. It no longer runs mkdep(1) during 'make depend', and the
|
|
'make depend' stage can safely be skipped now as it is auto ran
|
|
when building 'make all' and will generate all SRCS and DPSRCS before
|
|
building anything else. Dependencies are gathered at compile time with
|
|
-MF flags kept in separate .depend files per object file. Users should
|
|
run 'make cleandepend' once if using -DNO_CLEAN to clean out older
|
|
stale .depend files.
|
|
|
|
20160306:
|
|
On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
|
|
kernel modules. Therefore, if you load any kernel modules at boot time,
|
|
please install the boot loaders after you install the kernel, but before
|
|
rebooting, e.g.:
|
|
|
|
make buildworld
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make -C sys/boot install
|
|
<reboot in single user>
|
|
|
|
Then follow the usual steps, described in the General Notes section,
|
|
below.
|
|
|
|
20160305:
|
|
Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
|
|
see the 20141231 entry below for information about prerequisites and
|
|
upgrading, if you are not already using clang 3.5.0 or higher.
|
|
|
|
20160301:
|
|
The AIO subsystem is now a standard part of the kernel. The
|
|
VFS_AIO kernel option and aio.ko kernel module have been removed.
|
|
Due to stability concerns, asynchronous I/O requests are only
|
|
permitted on sockets and raw disks by default. To enable
|
|
asynchronous I/O requests on all file types, set the
|
|
vfs.aio.enable_unsafe sysctl to a non-zero value.
|
|
|
|
20160226:
|
|
The ELF object manipulation tool objcopy is now provided by the
|
|
ELF Tool Chain project rather than by GNU binutils. It should be a
|
|
drop-in replacement, with the addition of arm64 support. The
|
|
(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
|
|
to obtain the GNU version if necessary.
|
|
|
|
20160129:
|
|
Building ZFS pools on top of zvols is prohibited by default. That
|
|
feature has never worked safely; it's always been prone to deadlocks.
|
|
Using a zvol as the backing store for a VM guest's virtual disk will
|
|
still work, even if the guest is using ZFS. Legacy behavior can be
|
|
restored by setting vfs.zfs.vol.recursive=1.
|
|
|
|
20160119:
|
|
The NONE and HPN patches has been removed from OpenSSH. They are
|
|
still available in the security/openssh-portable port.
|
|
|
|
20160113:
|
|
With the addition of ypldap(8), a new _ypldap user is now required
|
|
during installworld. "mergemaster -p" can be used to add the user
|
|
prior to installworld, as documented in the handbook.
|
|
|
|
20151216:
|
|
The tftp loader (pxeboot) now uses the option root-path directive. As a
|
|
consequence it no longer looks for a pxeboot.4th file on the tftp
|
|
server. Instead it uses the regular /boot infrastructure as with the
|
|
other loaders.
|
|
|
|
20151211:
|
|
The code to start recording plug and play data into the modules has
|
|
been committed. While the old tools will properly build a new kernel,
|
|
a number of warnings about "unknown metadata record 4" will be produced
|
|
for an older kldxref. To avoid such warnings, make sure to rebuild
|
|
the kernel toolchain (or world). Make sure that you have r292078 or
|
|
later when trying to build 292077 or later before rebuilding.
|
|
|
|
20151207:
|
|
Debug data files are now built by default with 'make buildworld' and
|
|
installed with 'make installworld'. This facilitates debugging but
|
|
requires more disk space both during the build and for the installed
|
|
world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
|
|
in src.conf(5).
|
|
|
|
20151130:
|
|
r291527 changed the internal interface between the nfsd.ko and
|
|
nfscommon.ko modules. As such, they must both be upgraded to-gether.
|
|
__FreeBSD_version has been bumped because of this.
|
|
|
|
20151108:
|
|
Add support for unicode collation strings leads to a change of
|
|
order of files listed by ls(1) for example. To get back to the old
|
|
behaviour, set LC_COLLATE environment variable to "C".
|
|
|
|
Databases administrators will need to reindex their databases given
|
|
collation results will be different.
|
|
|
|
Due to a bug in install(1) it is recommended to remove the ancient
|
|
locales before running make installworld.
|
|
|
|
rm -rf /usr/share/locale/*
|
|
|
|
20151030:
|
|
The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
|
|
libcrypto.so.7 or libssl.so.7 must be recompiled.
|
|
|
|
20151020:
|
|
Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
|
|
Kernel modules isp_2400_multi and isp_2500_multi were removed and
|
|
should be replaced with isp_2400 and isp_2500 modules respectively.
|
|
|
|
20151017:
|
|
The build previously allowed using 'make -n' to not recurse into
|
|
sub-directories while showing what commands would be executed, and
|
|
'make -n -n' to recursively show commands. Now 'make -n' will recurse
|
|
and 'make -N' will not.
|
|
|
|
20151012:
|
|
If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
|
|
and etcupdate will now use this file. A custom sendmail.cf is now
|
|
updated via this mechanism rather than via installworld. If you had
|
|
excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
|
|
want to remove the exclusion or change it to "always install".
|
|
/etc/mail/sendmail.cf is now managed the same way regardless of
|
|
whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
|
|
SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
|
|
|
|
20151011:
|
|
Compatibility shims for legacy ATA device names have been removed.
|
|
It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
|
|
and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
|
|
environment variables, /dev/ad* and /dev/ar* symbolic links.
|
|
|
|
20151006:
|
|
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
|
|
Please see the 20141231 entry below for information about prerequisites
|
|
and upgrading, if you are not already using clang 3.5.0 or higher.
|
|
|
|
20150924:
|
|
Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
|
|
and renamed from .symbols to .debug. This reduces the size requirements
|
|
on the boot partition or file system and provides consistency with
|
|
userland debug files.
|
|
|
|
When using the supported kernel installation method the
|
|
/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
|
|
as is done with /boot/kernel.
|
|
|
|
Developers wishing to maintain the historical behavior of installing
|
|
debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
|
|
|
|
20150827:
|
|
The wireless drivers had undergone changes that remove the 'parent
|
|
interface' from the ifconfig -l output. The rc.d network scripts
|
|
used to check presence of a parent interface in the list, so old
|
|
scripts would fail to start wireless networking. Thus, etcupdate(3)
|
|
or mergemaster(8) run is required after kernel update, to update your
|
|
rc.d scripts in /etc.
|
|
|
|
20150827:
|
|
pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
|
|
These configurations are now automatically interpreted as
|
|
'scrub fragment reassemble'.
|
|
|
|
20150817:
|
|
Kernel-loadable modules for the random(4) device are back. To use
|
|
them, the kernel must have
|
|
|
|
device random
|
|
options RANDOM_LOADABLE
|
|
|
|
kldload(8) can then be used to load random_fortuna.ko
|
|
or random_yarrow.ko. Please note that due to the indirect
|
|
function calls that the loadable modules need to provide,
|
|
the build-in variants will be slightly more efficient.
|
|
|
|
The random(4) kernel option RANDOM_DUMMY has been retired due to
|
|
unpopularity. It was not all that useful anyway.
|
|
|
|
20150813:
|
|
The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
|
|
Control over building the ELF Tool Chain tools is now provided by
|
|
the WITHOUT_TOOLCHAIN knob.
|
|
|
|
20150810:
|
|
The polarity of Pulse Per Second (PPS) capture events with the
|
|
uart(4) driver has been corrected. Prior to this change the PPS
|
|
"assert" event corresponded to the trailing edge of a positive PPS
|
|
pulse and the "clear" event was the leading edge of the next pulse.
|
|
|
|
As the width of a PPS pulse in a typical GPS receiver is on the
|
|
order of 1 millisecond, most users will not notice any significant
|
|
difference with this change.
|
|
|
|
Anyone who has compensated for the historical polarity reversal by
|
|
configuring a negative offset equal to the pulse width will need to
|
|
remove that workaround.
|
|
|
|
20150809:
|
|
The default group assigned to /dev/dri entries has been changed
|
|
from 'wheel' to 'video' with the id of '44'. If you want to have
|
|
access to the dri devices please add yourself to the video group
|
|
with:
|
|
|
|
# pw groupmod video -m $USER
|
|
|
|
20150806:
|
|
The menu.rc and loader.rc files will now be replaced during
|
|
upgrades. Please migrate local changes to menu.rc.local and
|
|
loader.rc.local instead.
|
|
|
|
20150805:
|
|
GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
|
|
strings and strip have been removed. The src.conf(5) knob
|
|
WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
|
|
|
|
20150728:
|
|
As ZFS requires more kernel stack pages than is the default on some
|
|
architectures e.g. i386, it now warns if KSTACK_PAGES is less than
|
|
ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
|
|
|
|
Please consider using 'options KSTACK_PAGES=X' where X is greater
|
|
than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
|
|
|
|
20150706:
|
|
sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
|
|
and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
|
|
default, i.e., they will not contain "::". For example, instead
|
|
of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
|
|
to have a more specific match, such as different map entries for
|
|
IPv6:0:0 vs IPv6:0. This change requires that configuration
|
|
data (including maps, files, classes, custom ruleset, etc.) must
|
|
use the same format, so make certain such configuration data is
|
|
upgrading. As a very simple check search for patterns like
|
|
'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
|
|
behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
|
|
the cf option UseCompressedIPv6Addresses.
|
|
|
|
20150630:
|
|
The default kernel entropy-processing algorithm is now
|
|
Fortuna, replacing Yarrow.
|
|
|
|
Assuming you have 'device random' in your kernel config
|
|
file, the configurations allow a kernel option to override
|
|
this default. You may choose *ONE* of:
|
|
|
|
options RANDOM_YARROW # Legacy /dev/random algorithm.
|
|
options RANDOM_DUMMY # Blocking-only driver.
|
|
|
|
If you have neither, you get Fortuna. For most people,
|
|
read no further, Fortuna will give a /dev/random that works
|
|
like it always used to, and the difference will be irrelevant.
|
|
|
|
If you remove 'device random', you get *NO* kernel-processed
|
|
entropy at all. This may be acceptable to folks building
|
|
embedded systems, but has complications. Carry on reading,
|
|
and it is assumed you know what you need.
|
|
|
|
*PLEASE* read random(4) and random(9) if you are in the
|
|
habit of tweaking kernel configs, and/or if you are a member
|
|
of the embedded community, wanting specific and not-usual
|
|
behaviour from your security subsystems.
|
|
|
|
NOTE!! If you use RANDOM_DUMMY and/or have no 'device
|
|
random', you will NOT have a functioning /dev/random, and
|
|
many cryptographic features will not work, including SSH.
|
|
You may also find strange behaviour from the random(3) set
|
|
of library functions, in particular sranddev(3), srandomdev(3)
|
|
and arc4random(3). The reason for this is that the KERN_ARND
|
|
sysctl only returns entropy if it thinks it has some to
|
|
share, and with RANDOM_DUMMY or no 'device random' this
|
|
will never happen.
|
|
|
|
20150623:
|
|
An additional fix for the issue described in the 20150614 sendmail
|
|
entry below has been committed in revision 284717.
|
|
|
|
20150616:
|
|
FreeBSD's old make (fmake) has been removed from the system. It is
|
|
available as the devel/fmake port or via pkg install fmake.
|
|
|
|
20150615:
|
|
The fix for the issue described in the 20150614 sendmail entry
|
|
below has been committed in revision 284436. The work
|
|
around described in that entry is no longer needed unless the
|
|
default setting is overridden by a confDH_PARAMETERS configuration
|
|
setting of '5' or pointing to a 512 bit DH parameter file.
|
|
|
|
20150614:
|
|
ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
|
|
atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
|
|
and devel/kyua to version 0.20+ and adjust any calling code to work
|
|
with Kyuafile and kyua.
|
|
|
|
20150614:
|
|
The import of openssl to address the FreeBSD-SA-15:10.openssl
|
|
security advisory includes a change which rejects handshakes
|
|
with DH parameters below 768 bits. sendmail releases prior
|
|
to 8.15.2 (not yet released), defaulted to a 512 bit
|
|
DH parameter setting for client connections. To work around
|
|
this interoperability, sendmail can be configured to use a
|
|
2048 bit DH parameter by:
|
|
|
|
1. Edit /etc/mail/`hostname`.mc
|
|
2. If a setting for confDH_PARAMETERS does not exist or
|
|
exists and is set to a string beginning with '5',
|
|
replace it with '2'.
|
|
3. If a setting for confDH_PARAMETERS exists and is set to
|
|
a file path, create a new file with:
|
|
openssl dhparam -out /path/to/file 2048
|
|
4. Rebuild the .cf file:
|
|
cd /etc/mail/; make; make install
|
|
5. Restart sendmail:
|
|
cd /etc/mail/; make restart
|
|
|
|
A sendmail patch is coming, at which time this file will be
|
|
updated.
|
|
|
|
20150604:
|
|
Generation of legacy formatted entries have been disabled by default
|
|
in pwd_mkdb(8), as all base system consumers of the legacy formatted
|
|
entries were converted to use the new format by default when the new,
|
|
machine independent format have been added and supported since FreeBSD
|
|
5.x.
|
|
|
|
Please see the pwd_mkdb(8) manual page for further details.

Clang and llvm have been upgraded to 3.6.1 release. Please see the
|
|
20141231 entry below for information about prerequisites and upgrading,
|
|
if you are not already using 3.5.0 or higher.
|
|
|
|
20150521:
|
|
TI platform code switched to using vendor DTS files and this update
|
|
may break existing systems running on Beaglebone, Beaglebone Black,
|
|
and Pandaboard:
|
|
|
|
- dtb files should be regenerated/reinstalled. Filenames are the
|
|
same but content is different now
|
|
- GPIO addressing was changed, now each GPIO bank (32 pins per bank)
|
|
has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
|
|
addressing scheme is now pin 25 on /dev/gpioc3.
|
|
- Pandaboard: /etc/ttys should be updated, serial console device is
|
|
now /dev/ttyu2, not /dev/ttyu0
|
|
|
|
20150501:
|
|
soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
|
|
If you need the GNU extension from groff soelim(1), install groff
|
|
from package: pkg install groff, or via ports: textproc/groff.
|
|
|
|
20150423:
|
|
chmod, chflags, chown and chgrp now affect symlinks in -R mode as
|
|
defined in symlink(7); previously symlinks were silently ignored.
|
|
|
|
20150415:
|
|
The const qualifier has been removed from iconv(3) to comply with
|
|
POSIX. The ports tree is aware of this from r384038 onwards.
|
|
|
|
20150416:
|
|
Libraries specified by LIBADD in Makefiles must have a corresponding
|
|
DPADD_<lib> variable to ensure correct dependencies. This is now
|
|
enforced in src.libnames.mk.
|
|
|
|
20150324:
|
|
From legacy ata(4) driver was removed support for SATA controllers
|
|
supported by more functional drivers ahci(4), siis(4) and mvs(4).
|
|
Kernel modules ataahci and ataadaptec were removed completely,
|
|
replaced by ahci and mvs modules respectively.
|
|
|
|
20150315:
|
|
Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
|
|
the 20141231 entry below for information about prerequisites and
|
|
upgrading, if you are not already using 3.5.0 or higher.
|
|
|
|
20150307:
|
|
The 32-bit PowerPC kernel has been changed to a position-independent
|
|
executable. This can only be booted with a version of loader(8)
|
|
newer than January 31, 2015, so make sure to update both world and
|
|
kernel before rebooting.
|
|
|
|
20150217:
|
|
If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
|
|
but before r278950, the RNG was not seeded properly. Immediately
|
|
upgrade the kernel to r278950 or later and regenerate any keys (e.g.
|
|
ssh keys or openssl keys) that were generated w/ a kernel from that
|
|
range. This does not affect programs that directly used /dev/random
|
|
or /dev/urandom. All userland uses of arc4random(3) are affected.
|
|
|
|
20150210:
|
|
The autofs(4) ABI was changed in order to restore binary compatibility
|
|
with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
|
|
with the new kernel.
|
|
|
|
20150131:
|
|
The powerpc64 kernel has been changed to a position-independent
|
|
executable. This can only be booted with a new version of loader(8),
|
|
so make sure to update both world and kernel before rebooting.
|
|
|
|
20150118:
|
|
Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
|
|
only release, no new features have been added. Please see the 20141231
|
|
entry below for information about prerequisites and upgrading, if you
|
|
are not already using 3.5.0.
|
|
|
|
20150107:
|
|
ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
|
|
taken from the ELF Tool Chain project rather than GNU binutils. They
|
|
should be drop-in replacements, with the addition of arm64 support.
|
|
The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
|
|
binutils tools, if necessary. See 20150805 for updated information.
|
|
|
|
20150105:
|
|
The default Unbound configuration now enables remote control
|
|
using a local socket. Users who have already enabled the
|
|
local_unbound service should regenerate their configuration
|
|
by running "service local_unbound setup" as root.
|
|
|
|
20150102:
|
|
The GNU texinfo and GNU info pages have been removed.
|
|
To be able to view GNU info pages please install texinfo from ports.
|
|
|
|
20141231:
|
|
Clang, llvm and lldb have been upgraded to 3.5.0 release.
|
|
|
|
As of this release, a prerequisite for building clang, llvm and lldb is
|
|
a C++11 capable compiler and C++11 standard library. This means that to
|
|
be able to successfully build the cross-tools stage of buildworld, with
|
|
clang as the bootstrap compiler, your system compiler or cross compiler
|
|
should either be clang 3.3 or later, or gcc 4.8 or later, and your
|
|
system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
|
|
later.
|
|
|
|
On any standard FreeBSD 10.x or 11.x installation, where clang and
|
|
libc++ are on by default (that is, on x86 or arm), this should work out
|
|
of the box.
|
|
|
|
On 9.x installations where clang is enabled by default, e.g. on x86 and
|
|
powerpc, libc++ will not be enabled by default, so libc++ should be
|
|
built (with clang) and installed first. If both clang and libc++ are
|
|
missing, build clang first, then use it to build libc++.
|
|
|
|
On 8.x and earlier installations, upgrade to 9.x first, and then follow
|
|
the instructions for 9.x above.
|
|
|
|
Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
|
|
default, and do not build clang.
|
|
|
|
Many embedded systems are resource constrained, and will not be able to
|
|
build clang in a reasonable time, or in some cases at all. In those
|
|
cases, cross building bootable systems on amd64 is a workaround.
|
|
|
|
This new version of clang introduces a number of new warnings, of which
|
|
the following are most likely to appear:
|
|
|
|
-Wabsolute-value
|
|
|
|
This warns in two cases, for both C and C++:
|
|
* When the code is trying to take the absolute value of an unsigned
|
|
quantity, which is effectively a no-op, and almost never what was
|
|
intended. The code should be fixed, if at all possible. If you are
|
|
sure that the unsigned quantity can be safely cast to signed, without
|
|
loss of information or undefined behavior, you can add an explicit
|
|
cast, or disable the warning.
|
|
|
|
* When the code is trying to take an absolute value, but the called
|
|
abs() variant is for the wrong type, which can lead to truncation.
|
|
If you want to disable the warning instead of fixing the code, please
|
|
make sure that truncation will not occur, or it might lead to unwanted
|
|
side-effects.
|
|
|
|
-Wtautological-undefined-compare and
|
|
-Wundefined-bool-conversion
|
|
|
|
These warn when C++ code is trying to compare 'this' against NULL, while
|
|
'this' should never be NULL in well-defined C++ code. However, there is
|
|
some legacy (pre C++11) code out there, which actively abuses this
|
|
feature, which was less strictly defined in previous C++ versions.
|
|
|
|
Squid and openjdk do this, for example. The warning can be turned off
|
|
for C++98 and earlier, but compiling the code in C++11 mode might result
|
|
in unexpected behavior; for example, the parts of the program that are
|
|
unreachable could be optimized away.
|
|
|
|
20141222:
|
|
The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
|
|
kernel sources have been removed. The .h files remain, since some
|
|
utilities include them. This will need to be fixed later.
|
|
If "mount -t oldnfs ..." is attempted, it will fail.
|
|
If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
|
|
the utilities will report errors.
|
|
|
|
20141121:
|
|
The handling of LOCAL_LIB_DIRS has been altered to skip addition of
|
|
directories to top level SUBDIR variable when their parent
|
|
directory is included in LOCAL_DIRS. Users with build systems with
|
|
such hierarchies and without SUBDIR entries in the parent
|
|
directory Makefiles should add them or add the directories to
|
|
LOCAL_DIRS.
|
|
|
|
20141109:
|
|
faith(4) and faithd(8) have been removed from the base system. Faith
|
|
has been obsolete for a very long time.
|
|
|
|
20141104:
|
|
vt(4), the new console driver, is enabled by default. It brings
|
|
support for Unicode and double-width characters, as well as
|
|
support for UEFI and integration with the KMS kernel video
|
|
drivers.
|
|
|
|
You may need to update your console settings in /etc/rc.conf,
|
|
most probably the keymap. During boot, /etc/rc.d/syscons will
|
|
indicate what you need to do.
|
|
|
|
vt(4) still has issues and lacks some features compared to
|
|
syscons(4). See the wiki for up-to-date information:
|
|
https://wiki.freebsd.org/Newcons
|
|
|
|
If you want to keep using syscons(4), you can do so by adding
|
|
the following line to /boot/loader.conf:
|
|
kern.vty=sc
|
|
|
|
20141102:
|
|
pjdfstest has been integrated into kyua as an opt-in test suite.
|
|
Please see share/doc/pjdfstest/README for more details on how to
|
|
execute it.
|
|
|
|
20141009:
|
|
gperf has been removed from the base system for architectures
|
|
that use clang. Ports that require gperf will obtain it from the
|
|
devel/gperf port.
|
|
|
|
20140923:
|
|
pjdfstest has been moved from tools/regression/pjdfstest to
|
|
contrib/pjdfstest .
|
|
|
|
20140922:
|
|
At svn r271982, The default linux compat kernel ABI has been adjusted
|
|
to 2.6.18 in support of the linux-c6 compat ports infrastructure
|
|
update. If you wish to continue using the linux-f10 compat ports,
|
|
add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
|
|
encouraged to update their linux-compat packages to linux-c6 during
|
|
their next update cycle.
|
|
|
|
20140729:
|
|
The ofwfb driver, used to provide a graphics console on PowerPC when
|
|
using vt(4), no longer allows mmap() of all physical memory. This
|
|
will prevent Xorg on PowerPC with some ATI graphics cards from
|
|
initializing properly unless x11-servers/xorg-server is updated to
|
|
1.12.4_8 or newer.
|
|
|
|
20140723:
|
|
The xdev targets have been converted to using TARGET and
|
|
TARGET_ARCH instead of XDEV and XDEV_ARCH.
|
|
|
|
20140719:
|
|
The default unbound configuration has been modified to address
|
|
issues with reverse lookups on networks that use private
|
|
address ranges. If you use the local_unbound service, run
|
|
"service local_unbound setup" as root to regenerate your
|
|
configuration, then "service local_unbound reload" to load the
|
|
new configuration.
|
|
|
|
20140709:
|
|
The GNU texinfo and GNU info pages are not built and installed
|
|
anymore, WITH_INFO knob has been added to allow to built and install
|
|
them again.
|
|
UPDATE: see 20150102 entry on texinfo's removal
|
|
|
|
20140708:
|
|
The GNU readline library is now an INTERNALLIB - that is, it is
|
|
statically linked into consumers (GDB and variants) in the base
|
|
system, and the shared library is no longer installed. The
|
|
devel/readline port is available for third party software that
|
|
requires readline.
|
|
|
|
20140702:
|
|
The Itanium architecture (ia64) has been removed from the list of
|
|
known architectures. This is the first step in the removal of the
|
|
architecture.
|
|
|
|
20140701:
|
|
Commit r268115 has added NFSv4.1 server support, merged from
|
|
projects/nfsv4.1-server. Since this includes changes to the
|
|
internal interfaces between the NFS related modules, a full
|
|
build of the kernel and modules will be necessary.
|
|
__FreeBSD_version has been bumped.
|
|
|
|
20140629:
|
|
The WITHOUT_VT_SUPPORT kernel config knob has been renamed
|
|
WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
|
|
which differs from the behaviour controlled by this knob.)
|
|
|
|
20140619:
|
|
Maximal length of the serial number in CTL was increased from 16 to
|
|
64 chars, that breaks ABI. All CTL-related tools, such as ctladm
|
|
and ctld, need to be rebuilt to work with a new kernel.
|
|
|
|
20140606:
|
|
The libatf-c and libatf-c++ major versions were downgraded to 0 and
|
|
1 respectively to match the upstream numbers. They were out of
|
|
sync because, when they were originally added to FreeBSD, the
|
|
upstream versions were not respected. These libraries are private
|
|
and not yet built by default, so renumbering them should be a
|
|
non-issue. However, unclean source trees will yield broken test
|
|
programs once the operator executes "make delete-old-libs" after a
|
|
"make installworld".
|
|
|
|
Additionally, the atf-sh binary was made private by moving it into
|
|
/usr/libexec/. Already-built shell test programs will keep the
|
|
path to the old binary so they will break after "make delete-old"
|
|
is run.
|
|
|
|
If you are using WITH_TESTS=yes (not the default), wipe the object
|
|
tree and rebuild from scratch to prevent spurious test failures.
|
|
This is only needed once: the misnumbered libraries and misplaced
|
|
binaries have been added to OptionalObsoleteFiles.inc so they will
|
|
be removed during a clean upgrade.
|
|
|
|
20140512:
|
|
Clang and llvm have been upgraded to 3.4.1 release.
|
|
|
|
20140508:
|
|
We bogusly installed src.opts.mk in /usr/share/mk. This file should
|
|
be removed to avoid issues in the future (and has been added to
|
|
ObsoleteFiles.inc).
|
|
|
|
20140505:
|
|
/etc/src.conf now affects only builds of the FreeBSD src tree. In the
|
|
past, it affected all builds that used the bsd.*.mk files. The old
|
|
behavior was a bug, but people may have relied upon it. To get this
|
|
behavior back, you can .include /etc/src.conf from /etc/make.conf
|
|
(which is still global and isn't changed). This also changes the
|
|
behavior of incremental builds inside the tree of individual
|
|
directories. Set MAKESYSPATH to ".../share/mk" to do that.
|
|
Although this has survived make universe and some upgrade scenarios,
|
|
other upgrade scenarios may have broken. At least one form of
|
|
temporary breakage was fixed with MAKESYSPATH settings for buildworld
|
|
as well... In cases where MAKESYSPATH isn't working with this
|
|
setting, you'll need to set it to the full path to your tree.
|
|
|
|
One side effect of all this cleaning up is that bsd.compiler.mk
|
|
is no longer implicitly included by bsd.own.mk. If you wish to
|
|
use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
|
|
as well.
|
|
|
|
20140430:
|
|
The lindev device has been removed since /dev/full has been made a
|
|
standard device. __FreeBSD_version has been bumped.
|
|
|
|
20140424:
|
|
The knob WITHOUT_VI was added to the base system, which controls
|
|
building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
|
|
in order to reorder files share/termcap and didn't build ex(1) as a
|
|
build tool, so building/installing with WITH_VI is highly advised for
|
|
build hosts for older releases.
|
|
|
|
This issue has been fixed in stable/9 and stable/10 in r277022 and
|
|
r276991, respectively.
|
|
|
|
20140418:
|
|
The YES_HESIOD knob has been removed. It has been obsolete for
|
|
a decade. Please move to using WITH_HESIOD instead or your builds
|
|
will silently lack HESIOD.
|
|
|
|
20140405:
|
|
The uart(4) driver has been changed with respect to its handling
|
|
of the low-level console. Previously the uart(4) driver prevented
|
|
any process from changing the baudrate or the CLOCAL and HUPCL
|
|
control flags. By removing the restrictions, operators can make
|
|
changes to the serial console port without having to reboot.
|
|
However, when getty(8) is started on the serial device that is
|
|
associated with the low-level console, a misconfigured terminal
|
|
line in /etc/ttys will now have a real impact.
|
|
Before upgrading the kernel, make sure that /etc/ttys has the
|
|
serial console device configured as 3wire without baudrate to
|
|
preserve the previous behaviour. E.g:
|
|
ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
|
|
|
|
20140306:
|
|
Support for libwrap (TCP wrappers) in rpcbind was disabled by default
|
|
to improve performance. To re-enable it, if needed, run rpcbind
|
|
with command line option -W.
|
|
|
|
20140226:
|
|
Switched back to the GPL dtc compiler due to updates in the upstream
|
|
dts files not being supported by the BSDL dtc compiler. You will need
|
|
to rebuild your kernel toolchain to pick up the new compiler. Core dumps
|
|
may result while building dtb files during a kernel build if you fail
|
|
to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
|
|
|
|
20140216:
|
|
Clang and llvm have been upgraded to 3.4 release.
|
|
|
|
20140216:
|
|
The nve(4) driver has been removed. Please use the nfe(4) driver
|
|
for NVIDIA nForce MCP Ethernet adapters instead.
|
|
|
|
20140212:
|
|
An ABI incompatibility crept into the libc++ 3.4 import in r261283.
|
|
This could cause certain C++ applications using shared libraries built
|
|
against the previous version of libc++ to crash. The incompatibility
|
|
has now been fixed, but any C++ applications or shared libraries built
|
|
between r261283 and r261801 should be recompiled.
|
|
|
|
20140204:
|
|
OpenSSH will now ignore errors caused by kernel lacking of Capsicum
|
|
capability mode support. Please note that enabling the feature in
|
|
kernel is still highly recommended.
|
|
|
|
20140131:
|
|
OpenSSH is now built with sandbox support, and will use sandbox as
|
|
the default privilege separation method. This requires Capsicum
|
|
capability mode support in kernel.
|
|
|
|
20140128:
|
|
The libelf and libdwarf libraries have been updated to newer
|
|
versions from upstream. Shared library version numbers for
|
|
these two libraries were bumped. Any ports or binaries
|
|
requiring these two libraries should be recompiled.
|
|
__FreeBSD_version is bumped to 1100006.
|
|
|
|
20140110:
|
|
If a Makefile in a tests/ directory was auto-generating a Kyuafile
|
|
instead of providing an explicit one, this would prevent such
|
|
Makefile from providing its own Kyuafile in the future during
|
|
NO_CLEAN builds. This has been fixed in the Makefiles but manual
|
|
intervention is needed to clean an objdir if you use NO_CLEAN:
|
|
# find /usr/obj -name Kyuafile | xargs rm -f
|
|
|
|
20131213:
|
|
The behavior of gss_pseudo_random() for the krb5 mechanism
|
|
has changed, for applications requesting a longer random string
|
|
than produced by the underlying enctype's pseudo-random() function.
|
|
In particular, the random string produced from a session key of
|
|
enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
|
|
be different at the 17th octet and later, after this change.
|
|
The counter used in the PRF+ construction is now encoded as a
|
|
big-endian integer in accordance with RFC 4402.
|
|
__FreeBSD_version is bumped to 1100004.
|
|
|
|
20131108:
|
|
The WITHOUT_ATF build knob has been removed and its functionality
|
|
has been subsumed into the more generic WITHOUT_TESTS. If you were
|
|
using the former to disable the build of the ATF libraries, you
|
|
should change your settings to use the latter.
|
|
|
|
20131025:
|
|
The default version of mtree is nmtree which is obtained from
|
|
NetBSD. The output is generally the same, but may vary
|
|
slightly. If you found you need identical output adding
|
|
"-F freebsd9" to the command line should do the trick. For the
|
|
time being, the old mtree is available as fmtree.
|
|
|
|
20131014:
|
|
libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
|
|
This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
|
|
1.1.4_8 and verify bsdyml not linked in, before running "make
|
|
delete-old-libs":
|
|
# make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
|
|
or
|

General Notes
|
|
-------------
|
|
Avoid using make -j when upgrading. While generally safe, there are
|
|
sometimes problems using -j to upgrade. If your upgrade fails with
|
|
-j, please try again without -j. From time to time in the past there
|
|
have been problems using -j with buildworld and/or installworld. This
|
|
is especially true when upgrading between "distant" versions (eg one
|
|
that cross a major release boundary or several minor releases, or when
|
|
several months have passed on the -current branch).
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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, always follow
|
|
these two 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
|
|
|
|
The following example updates the ZFS boot block on the first
|
|
partition (freebsd-boot) of a GPT partitioned drive ada0:
|
|
"gpart bootcode -p /boot/gptzfsboot -i 1 ada0"
|
|
|
|
Non-boot pools do not need these updates.
|
|
|
|
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]
|
|
mergemaster -Fp [5]
|
|
make installworld
|
|
mergemaster -Fi [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]
|
|
mergemaster -Fp [5]
|
|
make installworld
|
|
mergemaster -Fi [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.
|
|
|
|
[3] From the bootblocks, boot -s, and then do
|
|
fsck -p
|
|
mount -u /
|
|
mount -a
|
|
cd src
|
|
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. The -U option is also useful to consider.
|
|
See mergemaster(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. It never hurts to do it all the time. You may need to
|
|
install a new mergemaster (cd src/usr.sbin/mergemaster && make
|
|
install) after the buildworld before this step if you last updated
|
|
from current before 20130425 or from -stable before 20130430.
|
|
|
|
[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] In order to have a kernel that can run the 4.x binaries needed to
|
|
do an installworld, you must include the COMPAT_FREEBSD4 option in
|
|
your kernel. Failure to do so may leave you with a system that is
|
|
hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is
|
|
required to run the 5.x binaries on more recent kernels. And so on
|
|
for COMPAT_FREEBSD6 and COMPAT_FREEBSD7.
|
|
|
|
Make sure that you merge any new devices from GENERIC since the
|
|
last time you updated your kernel config file.
|
|
|
|
[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.
