Updating Information for FreeBSD current users.
This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>.
See end of file for further details. For commonly done items, please see the
COMMON ITEMS: section later in the file. These instructions assume that you
basically know what you are doing. If not, then please consult the FreeBSD
handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
Items affecting the ports and packages system can be found in
/usr/ports/UPDATING. Please read that file before running portupgrade.
NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to
the tip of head, and then rebuild without this option. The bootstrap process
from older version of current across the gcc/clang cutover is a bit fragile.
NOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW:
FreeBSD 12.x has many debugging features turned on, in both the kernel
and userland. These features attempt to detect incorrect use of
system primitives, and encourage loud failure through extra sanity
checking and fail stop semantics. They also substantially impact
system performance. If you want to do performance measurement,
benchmarking, and optimization, you'll want to turn them off. This
includes various WITNESS- related kernel options, INVARIANTS, malloc
debugging flags in userland, and various verbose features in the
kernel. Many developers choose to disable these features on build
machines to maximize performance. (To completely disable malloc
debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
disable the most expensive debugging functionality run
"ln -s 'abort:false,junk:false' /etc/malloc.conf".)
****************************** SPECIAL WARNING: ******************************
Due to a bug in some versions of clang that's very hard to workaround in
the upgrade process, to upgrade to -current you must first upgrade
either stable/9 after r286035 or stable/10 after r286033 (including
10.3-RELEASE) or current after r286007 (including stable/11 and
11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so
you'll need to take the unusual step of upgrading to the tip of the
stable branch before moving to 11 or -current via a source upgrade.
stable/11 and 11.0-RELEASE have working newer compiler. This differs
from the historical situation where one could upgrade from anywhere on
the last couple of stable branches, so be careful.
If you're running a hybrid system on 9.x or 10.x with an updated clang
compiler or are using an supported external toolchain, the build system
will allow the upgrade. Otherwise it will print a reminder.
****************************** SPECIAL WARNING: ******************************
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
2017-04-14 05:32:03 +00:00
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 .
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.
- Add support for eMMC "partitions". Besides the user data area, i. e. the default partition, eMMC v4.41 and later devices can additionally provide up to: 1 enhanced user data area partition 2 boot partitions 1 RPMB (Replay Protected Memory Block) partition 4 general purpose partitions (optionally with a enhanced or extended attribute) Of these "partitions", only the enhanced user data area one actually slices the user data area partition and, thus, gets handled with the help of geom_flashmap(4). The other types of partitions have address space independent from the default partition and need to be switched to via CMD6 (SWITCH), i. e. constitute a set of additional "disks". The second kind of these "partitions" doesn't fit that well into the design of mmc(4) and mmcsd(4). I've decided to let mmcsd(4) hook all of these "partitions" up as disk(9)'s (except for the RPMB partition as it didn't seem to make much sense to be able to put a file-system there and may require authentication; therefore, RPMB partitions are solely accessible via the newly added IOCTL interface currently; see also below). This approach for one resulted in cleaner code. Second, it retains the notion of mmcsd(4) children corresponding to a single physical device each. With the addition of some layering violations, it also would have been possible for mmc(4) to add separate mmcsd(4) instances with one disk each for all of these "partitions", however. Still, both mmc(4) and mmcsd(4) share some common code now e. g. for issuing CMD6, which has been factored out into mmc_subr.c. Besides simply subdividing eMMC devices, some Intel NUCs having UEFI code in the boot partitions etc., another use case for the partition support is the activation of pseudo-SLC mode, which manufacturers of eMMC chips typically associate with the enhanced user data area and/ or the enhanced attribute of general purpose partitions. CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation. - Now that properly issuing CMD6 is crucial (so data isn't written to the wrong partition for example), make a step into the direction of correctly handling the timeout for these commands in the MMC layer. Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as recommended by relevant specifications. However, quite some work is left to be done in this regard; all other R1B-type commands done by the MMC layer also should be followed by a SEND_STATUS (CMD13), the erase timeout calculations/handling as documented in specifications are entirely ignored so far, the MMC layer doesn't provide timeouts applicable up to the bridge drivers and at least sdhci(4) currently is hardcoding 1 s as timeout for all command types unconditionally. Let alone already available return codes often not being checked in the MMC layer ... - Add an IOCTL interface to mmcsd(4); this is sufficiently compatible with Linux so that the GNU mmc-utils can be ported to and used with FreeBSD (note that due to the remaining deficiencies outlined above SANITIZE operations issued by/with `mmc` currently most likely will fail). These latter will be added to ports as sysutils/mmc-utils in a bit. Among others, the `mmc` tool of the GNU mmc-utils allows for partitioning eMMC devices (tested working). - For devices following the eMMC specification v4.41 or later, year 0 is 2013 rather than 1997; so correct this for assembling the device ID string properly. - Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at least for some of the above a matching pair is required. - In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC controllers as such in order to match the PCI one. Additionally, in the entry for the 80860F14 SDXC controller remove the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET. OKed by: imp Submitted by: ian (mmc_switch_status() implementation)

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.
2017-02-17 06:22:00 +00:00
20170216:
EISA bus support has been removed. The WITH_EISA option is no longer
valid.
20170215:
MCA bus support has been removed.
20170127:
The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
20170112:
The EM_MULTIQUEUE kernel configuration option is deprecated now that
the em(4) driver conforms to iflib specifications.
20170109:
The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
IFLIB. If you have a custom kernel configuration that excludes em(4)
but you use igb(4), you need to re-add em(4) to your custom configuration.
20161217:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20161124:
Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
Please see the 20141231 entry below for information about prerequisites
and upgrading, if you are not already using clang 3.5.0 or higher.
20161119:
The layout of the pmap structure has changed for powerpc to put the pmap
statistics at the front for all CPU variations. libkvm(3) and all tools
that link against it need to be recompiled.
add iic interface to ig4 driver, move isl and cyapa to iicbus Summary: The hardware does not expose a classic SMBus interface. Instead it has a lower level interface that can express a far richer I2C protocol than what smbus offers. However, the interface does not provide a way to explicitly generate the I2C stop and start conditions. It's only possible to request that the stop condition is generated after transferring the next byte in either direction. So, at least one data byte must always be transferred. Thus, some I2C sequences are impossible to generate, e.g., an equivalent of smbus quick command (<start>-<slave addr>-<r/w bit>-<stop>). At the same time isl(4) and cyapa(4) are moved to iicbus and now they use iicbus_transfer for communication. Previously they used smbus_trans() interface that is not defined by the SMBus protocol and was implemented only by ig4(4). In fact, that interface was impossible to implement for the typical SMBus controllers like intpm(4) or ichsmb(4) where a type of the SMBus command must be programmed. The plan is to remove smbus_trans() and all its uses. As an aside, the smbus_trans() method deviates from the standard, but perhaps backwards, FreeBSD convention of using 8-bit slave addresses (shifted by 1 bit to the left). The method expects 7-bit addresses. There is a user facing consequence of this change. A user must now provide device hints for isl and cyapa that specify an iicbus to use and a slave address on it. On Chromebook hardware where isl and cyapa devices are commonly found it is also possible to use a new chromebook_platform(4) driver that automatically configures isl and cyapa devices. There is no need to provide the device hints in that case, Right now smbus(4) driver tries to discover all slaves on the bus. That is very dangerous. Fortunately, the probing code uses smbus_trans() to do its job, so it is really enabled for ig4 only. The plan is to remove that auto-probing code and smbus_trans().

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.
2016-10-15 15:55:04 +00:00
- 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:
2016-09-18 15:55:57 +00:00
GNU rcs has been turned off by default. It can (temporarily) be built
again by adding WITH_RCS knob in src.conf.
Otherwise, GNU rcs is available from packages:
- rcs: Latest GPLv3 GNU rcs version.
- rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
20160918:
The backup_uses_rcs functionality has been removed from rc.subr.
20160908:
The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
two separate components, QUEUE_MACRO_DEBUG_TRACE and
QUEUE_MACRO_DEBUG_TRASH. Define both for the original
QUEUE_MACRO_DEBUG behavior.
20160824:
r304787 changed some ioctl interfaces between the iSCSI userspace
programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
rebuilt to work with new kernels. __FreeBSD_version has been bumped
to 1200005.
20160818:
The UDP receive code has been updated to only treat incoming UDP
packets that were addressed to an L2 broadcast address as L3
broadcast packets. It is not expected that this will affect any
standards-conforming UDP application. The new behaviour can be
disabled by setting the sysctl net.inet.udp.require_l2_bcast to
0.
20160818:
Remove the openbsd_poll system call.
__FreeBSD_version has been bumped because of this.
20160622:
The libc stub for the pipe(2) system call has been replaced with
a wrapper that calls the pipe2(2) system call and the pipe(2)
system call is now only implemented by the kernels that include
"options COMPAT_FREEBSD10" in their config file (this is the
default). Users should ensure that this option is enabled in
their kernel or upgrade userspace to r302092 before upgrading their
kernel.
20160527:
CAM will now strip leading spaces from SCSI disks' serial numbers.
2016-11-17 00:21:55 +00:00
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.

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.
Use uintmax_t (typedef'd to rman_res_t type) for rman ranges. On some architectures, u_long isn't large enough for resource definitions. Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but type `long' is only 32-bit. This extends rman's resources to uintmax_t. With this change, any resource can feasibly be placed anywhere in physical memory (within the constraints of the driver). Why uintmax_t and not something machine dependent, or uint64_t? Though it's possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on 32-bit architectures. 64-bit architectures should have plenty of RAM to absorb the increase on resource sizes if and when this occurs, and the number of resources on memory-constrained systems should be sufficiently small as to not pose a drastic overhead. That being said, uintmax_t was chosen for source clarity. If it's specified as uint64_t, all printf()-like calls would either need casts to uintmax_t, or be littered with PRI*64 macros. Casts to uintmax_t aren't horrible, but it would also bake into the API for resource_list_print_type() either a hidden assumption that entries get cast to uintmax_t for printing, or these calls would need the PRI*64 macros. Since source code is meant to be read more often than written, I chose the clearest path of simply using uintmax_t. Tested on a PowerPC p5020-based board, which places all device resources in 0xfxxxxxxxx, and has 8GB RAM.

20160317:
Resource range types have grown from unsigned long to uintmax_t. All
drivers, and anything using libdevinfo, need to be recompiled.
20160311:
WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
builds. It no longer runs mkdep(1) during 'make depend', and the
'make depend' stage can safely be skipped now as it is auto ran
when building 'make all' and will generate all SRCS and DPSRCS before
building anything else. Dependencies are gathered at compile time with
-MF flags kept in separate .depend files per object file. Users should
run 'make cleandepend' once if using -DNO_CLEAN to clean out older
stale .depend files.
20160306:
On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
kernel modules. Therefore, if you load any kernel modules at boot time,
please install the boot loaders after you install the kernel, but before
rebooting, e.g.:
make buildworld
make kernel KERNCONF=YOUR_KERNEL_HERE
make -C sys/boot install
<reboot in single user>
Then follow the usual steps, described in the General Notes section,
below.
20160305:
Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
see the 20141231 entry below for information about prerequisites and
upgrading, if you are not already using clang 3.5.0 or higher.
20160301:
The AIO subsystem is now a standard part of the kernel. The
VFS_AIO kernel option and aio.ko kernel module have been removed.
Due to stability concerns, asynchronous I/O requests are only
permitted on sockets and raw disks by default. To enable
asynchronous I/O requests on all file types, set the
vfs.aio.enable_unsafe sysctl to a non-zero value.
20160226:
The ELF object manipulation tool objcopy is now provided by the
ELF Tool Chain project rather than by GNU binutils. It should be a
drop-in replacement, with the addition of arm64 support. The
(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
to obtain the GNU version if necessary.
20160129:
Building ZFS pools on top of zvols is prohibited by default. That
feature has never worked safely; it's always been prone to deadlocks.
Using a zvol as the backing store for a VM guest's virtual disk will
still work, even if the guest is using ZFS. Legacy behavior can be
restored by setting vfs.zfs.vol.recursive=1.
20160119:
The NONE and HPN patches has been removed from OpenSSH. They are
still available in the security/openssh-portable port.
20160113:
With the addition of ypldap(8), a new _ypldap user is now required
during installworld. "mergemaster -p" can be used to add the user
prior to installworld, as documented in the handbook.
20151216:
The tftp loader (pxeboot) now uses the option root-path directive. As a
consequence it no longer looks for a pxeboot.4th file on the tftp
server. Instead it uses the regular /boot infrastructure as with the
other loaders.
20151211:
The code to start recording plug and play data into the modules has
been committed. While the old tools will properly build a new kernel,
a number of warnings about "unknown metadata record 4" will be produced
for an older kldxref. To avoid such warnings, make sure to rebuild
the kernel toolchain (or world). Make sure that you have r292078 or
later when trying to build 292077 or later before rebuilding.
20151207:
Debug data files are now built by default with 'make buildworld' and
installed with 'make installworld'. This facilitates debugging but
requires more disk space both during the build and for the installed
world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
in src.conf(5).
20151130:
r291527 changed the internal interface between the nfsd.ko and
nfscommon.ko modules. As such, they must both be upgraded to-gether.
__FreeBSD_version has been bumped because of this.
20151108:
Add support for unicode collation strings leads to a change of
order of files listed by ls(1) for example. To get back to the old
behaviour, set LC_COLLATE environment variable to "C".
Databases administrators will need to reindex their databases given
collation results will be different.

Due to a bug in install(1) it is recommended to remove the ancient
locales before running make installworld.

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.

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.
2015-09-24 16:56:44 +00:00
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.

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.

An additional fix for the issue described in the 20150614 sendmail
entry below has been been committed in revision 284717.
20150616:
FreeBSD's old make (fmake) has been removed from the system. It is
available as the devel/fmake port or via pkg install fmake.

The fix for the issue described in the 20150614 sendmail entry
below has been been committed in revision 284436. The work
around described in that entry is no longer needed unless the
default setting is overridden by a confDH_PARAMETERS configuration
setting of '5' or pointing to a 512 bit DH parameter file.
20150614:
ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
and devel/kyua to version 0.20+ and adjust any calling code to work
with Kyuafile and kyua.
20150614:
The import of openssl to address the FreeBSD-SA-15:10.openssl
security advisory includes a change which rejects handshakes
with DH parameters below 768 bits. sendmail releases prior
to 8.15.2 (not yet released), defaulted to a 512 bit
DH parameter setting for client connections. To work around
this interoperability, sendmail can be configured to use a
2048 bit DH parameter by:
2015-07-19 14:34:35 +00:00
1. Edit /etc/mail/`hostname`.mc
2. If a setting for confDH_PARAMETERS does not exist or
exists and is set to a string beginning with '5',
replace it with '2'.
3. If a setting for confDH_PARAMETERS exists and is set to
a file path, create a new file with:
openssl dhparam -out /path/to/file 2048
4. Rebuild the .cf file:
cd /etc/mail/; make; make install
5. Restart sendmail:
cd /etc/mail/; make restart
A sendmail patch is coming, at which time this file will be
updated.
20150604:
Generation of legacy formatted entries have been disabled by default
in pwd_mkdb(8), as all base system consumers of the legacy formatted
entries were converted to use the new format by default when the new,
machine independent format have been added and supported since FreeBSD
5.x.
Please see the pwd_mkdb(8) manual page for further details.
20150525:
Clang and llvm have been upgraded to 3.6.1 release. Please see the
20141231 entry below for information about prerequisites and upgrading,
if you are not already using 3.5.0 or higher.
20150521:
TI platform code switched to using vendor DTS files and this update
may break existing systems running on Beaglebone, Beaglebone Black,
and Pandaboard:
- dtb files should be regenerated/reinstalled. Filenames are the
same but content is different now
- GPIO addressing was changed, now each GPIO bank (32 pins per bank)
has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
addressing scheme is now pin 25 on /dev/gpioc3.
- Pandaboard: /etc/ttys should be updated, serial console device is
now /dev/ttyu2, not /dev/ttyu0
20150501:
soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
If you need the GNU extension from groff soelim(1), install groff
from package: pkg install groff, or via ports: textproc/groff.
20150423:
chmod, chflags, chown and chgrp now affect symlinks in -R mode as
defined in symlink(7); previously symlinks were silently ignored.
20150415:
The const qualifier has been removed from iconv(3) to comply with
POSIX. The ports tree is aware of this from r384038 onwards.
20150416:
Libraries specified by LIBADD in Makefiles must have a corresponding
DPADD_<lib> variable to ensure correct dependencies. This is now
enforced in src.libnames.mk.
20150324:
From legacy ata(4) driver was removed support for SATA controllers
supported by more functional drivers ahci(4), siis(4) and mvs(4).
Kernel modules ataahci and ataadaptec were removed completely,
replaced by ahci and mvs modules respectively.
20150315:
Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
the 20141231 entry below for information about prerequisites and
upgrading, if you are not already using 3.5.0 or higher.
20150307:
The 32-bit PowerPC kernel has been changed to a position-independent
executable. This can only be booted with a version of loader(8)
newer than January 31, 2015, so make sure to update both world and
kernel before rebooting.
20150217:
If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
but before r278950, the RNG was not seeded properly. Immediately
upgrade the kernel to r278950 or later and regenerate any keys (e.g.
ssh keys or openssl keys) that were generated w/ a kernel from that
2015-02-21 13:00:52 +00:00
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.
2015-07-19 14:34:35 +00:00
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.
2014-12-31 18:11:09 +00:00
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.
2014-12-31 18:11:09 +00:00
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.
2014-12-31 18:11:09 +00:00
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:
2015-01-05 13:46:37 +00:00
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.
2015-01-05 13:46:37 +00:00
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
2015-01-05 13:46:37 +00:00
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.
2014-07-01 22:32:11 +00:00
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.)
2014-06-24 18:56:45 +00:00
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.
2014-04-18 17:06:18 +00:00
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.
2014-03-03 16:34:42 +00:00
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.
2014-01-28 19:07:28 +00:00
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
# pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
20131010:
The stable/10 branch has been created in subversion from head
revision r256279.
20131010:
The rc.d/jail script has been updated to support jail(8)
configuration file. The "jail_<jname>_*" rc.conf(5) variables
for per-jail configuration are automatically converted to
/var/run/jail.<jname>.conf before the jail(8) utility is invoked.
This is transparently backward compatible. See below about some
incompatibilities and rc.conf(5) manual page for more details.
These variables are now deprecated in favor of jail(8) configuration
file. One can use "rc.d/jail config <jname>" command to generate
a jail(8) configuration file in /var/run/jail.<jname>.conf without
running the jail(8) utility. The default pathname of the
configuration file is /etc/jail.conf and can be specified by
using $jail_conf or $jail_<jname>_conf variables.
Please note that jail_devfs_ruleset accepts an integer at
this moment. Please consider to rewrite the ruleset name
with an integer.
20130930:
BIND has been removed from the base system. If all you need
is a local resolver, simply enable and start the local_unbound
service instead. Otherwise, several versions of BIND are
available in the ports tree. The dns/bind99 port is one example.
With this change, nslookup(1) and dig(1) are no longer in the base
system. Users should instead use host(1) and drill(1) which are
in the base system. Alternatively, nslookup and dig can
be obtained by installing the dns/bind-tools port.
20130916:
With the addition of unbound(8), a new unbound user is now
required during installworld. "mergemaster -p" can be used to
add the user prior to installworld, as documented in the handbook.
20130911:
OpenSSH is now built with DNSSEC support, and will by default
silently trust signed SSHFP records. This can be controlled with
the VerifyHostKeyDNS client configuration setting. DNSSEC support
can be disabled entirely with the WITHOUT_LDNS option in src.conf.
20130906:
The GNU Compiler Collection and C++ standard library (libstdc++)
are no longer built by default on platforms where clang is the system
compiler. You can enable them with the WITH_GCC and WITH_GNUCXX
2015-07-19 14:34:35 +00:00
options in src.conf.
20130905:
The PROCDESC kernel option is now part of the GENERIC kernel
configuration and is required for the rwhod(8) to work.
If you are using custom kernel configuration, you should include
'options PROCDESC'.
20130905:
The API and ABI related to the Capsicum framework was modified
in backward incompatible way. The userland libraries and programs
have to be recompiled to work with the new kernel. This includes the
following libraries and programs, but the whole buildworld is
advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl,
kdump, procstat, rwho, rwhod, uniq.
20130903:
AES-NI intrinsic support has been added to gcc. The AES-NI module
has been updated to use this support. A new gcc is required to build
the aesni module on both i386 and amd64.
20130821:
The PADLOCK_RNG and RDRAND_RNG kernel options are now devices.
Thus "device padlock_rng" and "device rdrand_rng" should be
used instead of "options PADLOCK_RNG" & "options RDRAND_RNG".
20130813:
WITH_ICONV has been split into two feature sets. WITH_ICONV now
enables just the iconv* functionality and is now on by default.
WITH_LIBICONV_COMPAT enables the libiconv api and link time
compatibility. Set WITHOUT_ICONV to build the old way.
If you have been using WITH_ICONV before, you will very likely
need to turn on WITH_LIBICONV_COMPAT.
20130806:
INVARIANTS option now enables DEBUG for code with OpenSolaris and
Illumos origin, including ZFS. If you have INVARIANTS in your
kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG
explicitly.
DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS)
locks if WITNESS option was set. Because that generated a lot of
witness(9) reports and all of them were believed to be false
positives, this is no longer done. New option OPENSOLARIS_WITNESS
can be used to achieve the previous behavior.
20130806:
Timer values in IPv6 data structures now use time_uptime instead
of time_second. Although this is not a user-visible functional
change, userland utilities which directly use them---ndp(8),
rtadvd(8), and rtsold(8) in the base system---need to be updated
to r253970 or later.
20130802:
find -delete can now delete the pathnames given as arguments,
instead of only files found below them or if the pathname did
not contain any slashes. Formerly, the following error message
would result:
find: -delete: <path>: relative path potentially not safe
Deleting the pathnames given as arguments can be prevented
without error messages using -mindepth 1 or by changing
directory and passing "." as argument to find. This works in the
old as well as the new version of find.
20130726:
Behavior of devfs rules path matching has been changed.
Pattern is now always matched against fully qualified devfs
path and slash characters must be explicitly matched by
slashes in pattern (FNM_PATHNAME). Rulesets involving devfs
subdirectories must be reviewed.
20130716:
The default ARM ABI has changed to the ARM EABI. The old ABI is
incompatible with the ARM EABI and all programs and modules will
need to be rebuilt to work with a new kernel.
To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set.
NOTE: Support for the old ABI will be removed in the future and
users are advised to upgrade.
20130709:
pkg_install has been disconnected from the build if you really need it
you should add WITH_PKGTOOLS in your src.conf(5).
20130709:
Most of network statistics structures were changed to be able
keep 64-bits counters. Thus all tools, that work with networking
2013-07-14 20:22:16 +00:00
statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.)
20130618:
Fix a bug that allowed a tracing process (e.g. gdb) to write
to a memory-mapped file in the traced process's address space
even if neither the traced process nor the tracing process had
write access to that file.
20130615:
CVS has been removed from the base system. An exact copy
of the code is available from the devel/cvs port.
20130613:
Some people report the following error after the switch to bmake:
make: illegal option -- J
usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable]
...
*** [buildworld] Error code 2
this likely due to an old instance of make in
${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE})
which src/Makefile will use that blindly, if it exists, so if
you see the above error:
rm -rf `make -V MAKEPATH`
should resolve it.
20130516:
Use bmake by default.
Whereas before one could choose to build with bmake via
-DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old
make. The goal is to remove these knobs for 10-RELEASE.
It is worth noting that bmake (like gmake) treats the command
line as the unit of failure, rather than statements within the
command line. Thus '(cd some/where && dosomething)' is safer
than 'cd some/where; dosomething'. The '()' allows consistent
behavior in parallel build.
20130429:
Fix a bug that allows NFS clients to issue READDIR on files.
20130426:
The WITHOUT_IDEA option has been removed because
the IDEA patent expired.
20130426:
The sysctl which controls TRIM support under ZFS has been renamed
from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been
enabled by default.
20130425:
The mergemaster command now uses the default MAKEOBJDIRPREFIX
rather than creating it's own in the temporary directory in
order allow access to bootstrapped versions of tools such as
install and mtree. When upgrading from version of FreeBSD where
the install command does not support -l, you will need to
install a new mergemaster command if mergemaster -p is required.
This can be accomplished with the command (cd src/usr.sbin/mergemaster
&& make install).
2013-04-06 13:47:44 +00:00
20130404:
Legacy ATA stack, disabled and replaced by new CAM-based one since
FreeBSD 9.0, completely removed from the sources. Kernel modules
atadisk and atapi*, user-level tools atacontrol and burncd are
removed. Kernel option `options ATA_CAM` is now permanently enabled
and removed.
20130319:
SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2)
and socketpair(2). Software, in particular Kerberos, may
automatically detect and use these during building. The resulting
binaries will not work on older kernels.
20130308:
CTL_DISABLE has also been added to the sparc64 GENERIC (for further
information, see the respective 20130304 entry).
20130304:
Recent commits to callout(9) changed the size of struct callout,
so the KBI is probably heavily disturbed. Also, some functions
in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced
by macros. Every kernel module using it won't load, so rebuild
is requested.
The ctl device has been re-enabled in GENERIC for i386 and amd64,
but does not initialize by default (because of the new CTL_DISABLE
option) to save memory. To re-enable it, remove the CTL_DISABLE
option from the kernel config file or set kern.cam.ctl.disable=0
in /boot/loader.conf.
20130301:
The ctl device has been disabled in GENERIC for i386 and amd64.
This was done due to the extra memory being allocated at system
initialisation time by the ctl driver which was only used if
a CAM target device was created. This makes a FreeBSD system
unusable on 128MB or less of RAM.
20130208:
A new compression method (lz4) has been merged to -HEAD. Please
refer to zpool-features(7) for more information.
Please refer to the "ZFS notes" section of this file for information
on upgrading boot ZFS pools.
20130129:
A BSD-licensed patch(1) variant has been added and is installed
as bsdpatch, being the GNU version the default patch.
To inverse the logic and use the BSD-licensed one as default,
while having the GNU version installed as gnupatch, rebuild
2013-01-30 10:23:38 +00:00
and install world with the WITH_BSD_PATCH knob set.
20130121:
Due to the use of the new -l option to install(1) during build
and install, you must take care not to directly set the INSTALL
make variable in your /etc/make.conf, /etc/src.conf, or on the
command line. If you wish to use the -C flag for all installs
you may be able to add INSTALL+=-C to /etc/make.conf or
/etc/src.conf.
20130118:
The install(1) option -M has changed meaning and now takes an
argument that is a file or path to append logs to. In the
unlikely event that -M was the last option on the command line
and the command line contained at least two files and a target
directory the first file will have logs appended to it. The -M
option served little practical purpose in the last decade so its
use is expected to be extremely rare.
20121223:
After switching to Clang as the default compiler some users of ZFS
on i386 systems started to experience stack overflow kernel panics.
Please consider using 'options KSTACK_PAGES=4' in such configurations.
20121222:
GEOM_LABEL now mangles label names read from file system metadata.
Mangling affect labels containing spaces, non-printable characters,
'%' or '"'. Device names in /etc/fstab and other places may need to
be updated.
20121217:
By default, only the 10 most recent kernel dumps will be saved. To
restore the previous behaviour (no limit on the number of kernel dumps
stored in the dump directory) add the following line to /etc/rc.conf:
savecore_flags=""
20121201:
With the addition of auditdistd(8), a new auditdistd user is now
required during installworld. "mergemaster -p" can be used to
add the user prior to installworld, as documented in the handbook.
20121117:
The sin6_scope_id member variable in struct sockaddr_in6 is now
filled by the kernel before passing the structure to the userland via
sysctl or routing socket. This means the KAME-specific embedded scope
id in sin6_addr.s6_addr[2] is always cleared in userland application.
This behavior can be controlled by net.inet6.ip6.deembed_scopeid.
__FreeBSD_version is bumped to 1000025.
20121105:
On i386 and amd64 systems WITH_CLANG_IS_CC is now the default.
This means that the world and kernel will be compiled with clang
and that clang will be installed as /usr/bin/cc, /usr/bin/c++,
and /usr/bin/cpp. To disable this behavior and revert to building
with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions
of current may need to bootstrap WITHOUT_CLANG first if the clang
build fails (its compatibility window doesn't extend to the 9 stable
branch point).
20121102:
The IPFIREWALL_FORWARD kernel option has been removed. Its
functionality now turned on by default.
20121023:
The ZERO_COPY_SOCKET kernel option has been removed and
split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP.
NB: SOCKET_SEND_COW uses the VM page based copy-on-write
mechanism which is not safe and may result in kernel crashes.
NB: The SOCKET_RECV_PFLIP mechanism is useless as no current
driver supports disposeable external page sized mbuf storage.
Proper replacements for both zero-copy mechanisms are under
consideration and will eventually lead to complete removal
of the two kernel options.
20121023:
The IPv4 network stack has been converted to network byte
order. The following modules need to be recompiled together
with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4),
pf(4), ipfw(4), ng_ipfw(4), stf(4).
20121022:
Support for non-MPSAFE filesystems was removed from VFS. The
VFS_VERSION was bumped, all filesystem modules shall be
recompiled.
20121018:
All the non-MPSAFE filesystems have been disconnected from
the build. The full list includes: codafs, hpfs, ntfs, nwfs,
portalfs, smbfs, xfs.
20121016:
The interface cloning API and ABI has changed. The following
modules need to be recompiled together with kernel:
ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4),
vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4),
faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4).
20121015:
The sdhci driver was split in two parts: sdhci (generic SD Host
Controller logic) and sdhci_pci (actual hardware driver).
No kernel config modifications are required, but if you
load sdhc as a module you must switch to sdhci_pci instead.
20121014:
Import the FUSE kernel and userland support into base system.
20121013:
The GNU sort(1) program has been removed since the BSD-licensed
sort(1) has been the default for quite some time and no serious
problems have been reported. The corresponding WITH_GNU_SORT
2012-10-13 19:37:58 +00:00
knob has also gone.
20121006:
The pfil(9) API/ABI for AF_INET family has been changed. Packet
filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled
with new kernel.
20121001:
The net80211(4) ABI has been changed to allow for improved driver
PS-POLL and power-save support. All wireless drivers need to be
recompiled to work with the new kernel.
20120913:
The random(4) support for the VIA hardware random number
generator (`PADLOCK') is no longer enabled unconditionally.
Add the padlock_rng device in the custom kernel config if
needed. The GENERIC kernels on i386 and amd64 do include the
device, so the change only affects the custom kernel
configurations.
Merge the projects/pf/head branch, that was worked on for last six months, into head. The most significant achievements in the new code: o Fine grained locking, thus much better performance. o Fixes to many problems in pf, that were specific to FreeBSD port. New code doesn't have that many ifdefs and much less OpenBSDisms, thus is more attractive to our developers. Those interested in details, can browse through SVN log of the projects/pf/head branch. And for reference, here is exact list of revisions merged: r232043, r232044, r232062, r232148, r232149, r232150, r232298, r232330, r232332, r232340, r232386, r232390, r232391, r232605, r232655, r232656, r232661, r232662, r232663, r232664, r232673, r232691, r233309, r233782, r233829, r233830, r233834, r233835, r233836, r233865, r233866, r233868, r233873, r234056, r234096, r234100, r234108, r234175, r234187, r234223, r234271, r234272, r234282, r234307, r234309, r234382, r234384, r234456, r234486, r234606, r234640, r234641, r234642, r234644, r234651, r235505, r235506, r235535, r235605, r235606, r235826, r235991, r235993, r236168, r236173, r236179, r236180, r236181, r236186, r236223, r236227, r236230, r236252, r236254, r236298, r236299, r236300, r236301, r236397, r236398, r236399, r236499, r236512, r236513, r236525, r236526, r236545, r236548, r236553, r236554, r236556, r236557, r236561, r236570, r236630, r236672, r236673, r236679, r236706, r236710, r236718, r237154, r237155, r237169, r237314, r237363, r237364, r237368, r237369, r237376, r237440, r237442, r237751, r237783, r237784, r237785, r237788, r237791, r238421, r238522, r238523, r238524, r238525, r239173, r239186, r239644, r239652, r239661, r239773, r240125, r240130, r240131, r240136, r240186, r240196, r240212. I'd like to thank people who participated in early testing: Tested by: Florian Smeets <flo freebsd.org> Tested by: Chekaluk Vitaly <artemrts ukr.net> Tested by: Ben Wilber <ben desync.com> Tested by: Ian FREISLICH <ianf cloudseed.co.za>
2012-09-08 06:41:54 +00:00
20120908:
The pf(4) packet filter ABI has been changed. pfctl(8) and
snmp_pf module need to be recompiled to work with new kernel.
20120828:
A new ZFS feature flag "com.delphix:empty_bpobj" has been merged
to -HEAD. Pools that have empty_bpobj in active state can not be
imported read-write with ZFS implementations that do not support
this feature. For more information read the zpool-features(5)
manual page.
20120727:
The sparc64 ZFS loader has been changed to no longer try to auto-
detect ZFS providers based on diskN aliases but now requires these
2015-07-19 14:34:35 +00:00
to be explicitly listed in the OFW boot-device environment variable.
20120712:
The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring
libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are
configuration changes. Make sure to merge /etc/ssl/openssl.cnf.
20120712:
The following sysctls and tunables have been renamed for consistency
with other variables:
kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered
kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered
2012-06-28 08:22:00 +00:00
20120628:
The sort utility has been replaced with BSD sort. For now, GNU sort
is also available as "gnusort" or the default can be set back to
GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be
installed as "bsdsort".
20120611:
A new version of ZFS (pool version 5000) has been merged to -HEAD.
Starting with this version the old system of ZFS pool versioning
is superseded by "feature flags". This concept enables forward
compatibility against certain future changes in functionality of ZFS
pools. The first read-only compatible "feature flag" for ZFS pools
is named "com.delphix:async_destroy". For more information
read the new zpool-features(5) manual page.
Please refer to the "ZFS notes" section of this file for information
on upgrading boot ZFS pools.
20120417:
The malloc(3) implementation embedded in libc now uses sources imported
as contrib/jemalloc. The most disruptive API change is to
/etc/malloc.conf. If your system has an old-style /etc/malloc.conf,
delete it prior to installworld, and optionally re-create it using the
new format after rebooting. See malloc.conf(5) for details
(specifically the TUNING section and the "opt.*" entries in the MALLCTL
NAMESPACE section).
20120328:
Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb
is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is
now spelled mips. This is to aid compatibility with third-party
software that expects this naming scheme in uname(3). Little-endian
2013-05-01 07:13:36 +00:00
settings are unchanged. If you are updating a big-endian mips64 machine
from before this change, you may need to set MACHINE_ARCH=mips64 in
your environment before the new build system will recognize your machine.
20120306:
Disable by default the option VFS_ALLOW_NONMPSAFE for all supported
platforms.
20120229:
Now unix domain sockets behave "as expected" on nullfs(5). Previously
nullfs(5) did not pass through all behaviours to the underlying layer,
as a result if we bound to a socket on the lower layer we could connect
only to the lower path; if we bound to the upper layer we could connect
only to the upper path. The new behavior is one can connect to both the
lower and the upper paths regardless what layer path one binds to.
20120211:
The getifaddrs upgrade path broken with 20111215 has been restored.
If you have upgraded in between 20111215 and 20120209 you need to
recompile libc again with your kernel. You still need to recompile
world to be able to configure CARP but this restriction already
comes from 20111215.
20120114:
The set_rcvar() function has been removed from /etc/rc.subr. All
base and ports rc.d scripts have been updated, so if you have a
port installed with a script in /usr/local/etc/rc.d you can either
hand-edit the rcvar= line, or reinstall the port.
An easy way to handle the mass-update of /etc/rc.d:
rm /etc/rc.d/* && mergemaster -i
20120109:
panic(9) now stops other CPUs in the SMP systems, disables interrupts
on the current CPU and prevents other threads from running.
This behavior can be reverted using the kern.stop_scheduler_on_panic
tunable/sysctl.
The new behavior can be incompatible with kern.sync_on_panic.
20111215:
The carp(4) facility has been changed significantly. Configuration
of the CARP protocol via ifconfig(8) has changed, as well as format
of CARP events submitted to devd(8) has changed. See manual pages
for more information. The arpbalance feature of carp(4) is currently
not supported anymore.
Size of struct in_aliasreq, struct in6_aliasreq has changed. User
utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8),
need to be recompiled.
2011-11-30 20:08:30 +00:00
20111122:
The acpi_wmi(4) status device /dev/wmistat has been renamed to
/dev/wmistat0.
20111108:
The option VFS_ALLOW_NONMPSAFE option has been added in order to
explicitely support non-MPSAFE filesystems.
It is on by default for all supported platform at this present
time.
20111101:
The broken amd(4) driver has been replaced with esp(4) in the amd64,
i386 and pc98 GENERIC kernel configuration files.
20110930:
sysinstall has been removed
20110923:
The stable/9 branch created in subversion. This corresponds to the
RELENG_9 branch in CVS.
COMMON ITEMS:
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 upgade 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

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 just build a kernel when you know that it won't mess you up
--------------------------------------------------------------
This assumes you are already running a CURRENT system. Replace
${arch} with the architecture of your machine (e.g. "i386",
"arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc).
cd src/sys/${arch}/conf
config KERNEL_NAME_HERE
cd ../compile/KERNEL_NAME_HERE
make depend
make
2004-06-22 10:33:58 +00:00
make install
If this fails, go to the "To build a kernel" section.
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 kernel 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 kernel KERNCONF=YOUR_KERNEL_HERE [8]
[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
2002-04-25 02:14:48 +00:00
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 noop. 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] When checking out sources, you must include the -P flag to have
cvs prune empty directories.
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.
