15 NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
16 from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to
17 the tip of head, and then rebuild without this option. The bootstrap process
18 from older version of current across the gcc/clang cutover is a bit fragile.

130 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl.
131 As of be70c7a50d32 it is no longer used by userspace, but it does mean
132 users may not be able to enumerate pf states if they update the kernel
133 past c021ff986e2b without first updating userspace past be70c7a50d32.
136 The 20210707 awk update brought in a change in behavior. This has
137 been corrected as of d4d252c49976. Between these dates, if you
138 installed a new awk binary, you may not be able to build a new
139 kernel because the change in behavior affected the genoffset
140 script used to build the kernel. If you did update, the fix is
141 to update your sources past the above hash and do
144 % sudo -E make install
145 to enable building kernels again.
148 awk has been updated to the latest one-true-awk version 20210215.
149 This contains a number of minor bug fixes.
152 Commit 6ae32cc8182f changed the internal KAPI between the krpc and
153 nfsd modules. As such, both need to be rebuilt from sources.
154 Bump __FreeBSD_version to 1202508.
157 Commit e9959506d2cc changed the internal KAPI between the
158 nscl.ko and nfscommon.ko modules, so they both need to be
159 rebuilt from sources.
162 Commit 0a1fdb867c72 changed the internal KAPI between
163 the krpc and NFS. As such, the krpc, nfscommon and
164 nfscl modules must all be rebuilt from sources.
165 Without this patch, NFSv4.1 mounts should not
166 be done with the nfscbd(8) daemon running, to avoid
167 needing a working back channel for server->client RPCs.
170 The make.conf(5) MALLOC_PRODUCTION variable, used for disabling and
171 enabling assertions and statistics gathering in malloc(3), has been
172 migrated to a src.conf(5) WITH/WITHOUT_MALLOC_PRODUCTION option.
174 On stable branches, WITH_MALLOC_PRODUCTION is set by default, which
175 means that malloc(3) has assertions and statistics gathering disabled,
176 for improved performance.
178 For backwards compatibility, the make.conf(5) MALLOC_PRODUCTION is still
179 honored, but it is now deprecated and undocumented.
182 The resume code now notifies devd with the 'kernel' system
183 rather than the old 'kern' subsystem to be consistent with
184 other use. The old notification will be created as well, but
185 will be removed prior to FreeBSD 14.0.
188 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
189 been upgraded to 10.0.1. Please see the 20141231 entry below for
190 information about prerequisites and upgrading, if you are not already
191 using clang 3.5.0 or higher.
194 read(2) of a directory fd is now rejected by default. root may
195 re-enable it for the entire system with the
196 security.bsd.allow_read_dir sysctl(8) MIB.
198 It may be advised to setup aliases for grep to default to `-d skip` if
199 commonly non-recursively grepping a list that includes directories and
200 the potential for the resulting stderr output is not tolerable. Example
201 aliases are now installed, commented out, in /root/.cshrc.
204 Upstream DTS from Linux 5.6 was merged and they now have the SID
205 and THS (Secure ID controller and THermal Sensor) node present.
206 The DTB overlays have now been removed from the tree for the H3/H5 and
207 A64 SoCs and the aw_sid and aw_thermal driver have been updated to
208 deal with upstream DTS. If you are using those overlays you need to
209 remove them from loader.conf and update the DTBs on the FAT partition.
212 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
213 been upgraded to 10.0.0. Please see the 20141231 entry below for
214 information about prerequisites and upgrading, if you are not already
215 using clang 3.5.0 or higher.
218 The root certificates of the Mozilla CA Certificate Store have been
219 imported into the base system and can be managed with the certctl(8)
220 utility. If you have installed the security/ca_root_nss port or package
221 with the ETCSYMLINK option (the default), be advised that there may be
222 differences between those included in the port and those included in
223 base due to differences in nss branch used as well as general update
224 frequency. Note also that certctl(8) cannot manage certs in the
225 format used by the security/ca_root_nss port.
228 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
229 been upgraded to 9.0.1. Please see the 20141231 entry below for
230 information about prerequisites and upgrading, if you are not already
231 using clang 3.5.0 or higher.
234 The nctgpio and wbwd drivers have been moved to the superio bus.
235 If you have one of these drivers in a kernel configuration, then
236 you should add device superio to it. If you use one of these drivers
237 as a module and you compile a custom set of modules, then you should
238 add superio to the set.
241 The tap(4) driver has been folded into tun(4), and the module has been
242 renamed to tuntap. You should update any kld_list="if_tap" or
243 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
244 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
245 module instead, and "device tap" or "device tun" entries in kernel
246 config files to select the tuntap device instead.
249 ntpd no longer by default locks its pages in memory, allowing them
250 to be paged out by the kernel. Use rlimit memlock to restore
251 historic BSD behaviour. For example, add "rlimit memlock 32"
252 to ntp.conf to lock up to 32 MB of ntpd address space in memory.
255 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
256 and the "-o sync_unmount" and "-o init_backgrounded" mount options have
257 been removed from mount_fusefs(8). You can safely remove them from
258 your scripts, because they had no effect.
260 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
261 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
262 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
263 sysctls have been removed. If you felt the need to set any of them to
264 a non-default value, please tell asomers@FreeBSD.org why.
267 The fuse(4) module has been renamed to fusefs(4) for consistency with
268 other filesystems. You should update any kld_load="fuse" entries in
269 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
270 "options FUSE" enties in kernel config files.
273 Default permissions on the /var/account/acct file (and copies of it
274 rotated by periodic daily scripts) are changed from 0644 to 0640
275 because the file contains sensitive information that should not be
276 world-readable. If the /var/account directory must be created by
277 rc.d/accounting, the mode used is now 0750. Admins who use the
278 accounting feature are encouraged to change the mode of an existing
279 /var/account directory to 0750 or 0700.
282 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
283 been upgraded to 8.0.1. Please see the 20141231 entry below for
284 information about prerequisites and upgrading, if you are not already
285 using clang 3.5.0 or higher.
288 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc
289 functionality needed for the RETPOLINE option should work properly
290 again. The RETPOLINE option has been removed from BROKEN_OPTIONS.
293 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
294 8.0.0. Please see the 20141231 entry below for information about
295 prerequisites and upgrading, if you are not already using clang 3.5.0
299 The RETPOLINE option produces non-functional ifunc-using binaries
300 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS).
301 Once Clang 8 is merged it may be enabled again.
304 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
305 7.0.1. Please see the 20141231 entry below for information about
306 prerequisites and upgrading, if you are not already using clang 3.5.0
310 geom_uzip(4) depends on the new module xz. If geom_uzip is statically
311 compiled into your custom kernel, add 'device xz' statement to the
315 Iflib is no longer unconditionally compiled into the kernel. Drivers
316 using iflib and statically compiled into the kernel, now require
317 the 'device iflib' config option. For the same drivers loaded as
318 modules on kernels not having 'device iflib', the iflib.ko module
319 is loaded automatically.
322 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
323 in the same as it is applied to NFSv2 and 3. This implies that NFSv4
324 servers that have vfs.nfsd.nfs_privport set will only allow mounts
325 from clients using a reserved port#. Since both the FreeBSD and Linux
326 NFSv4 clients use reserved port#s by default, this should not affect
330 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
331 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
332 it produces broken binaries when ifuncs are in use. Users needing
333 GNU ld should install the binutils port or package.
336 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
337 has been converted to a port (misc/ctm) and will be removed from
338 FreeBSD-13. A depreciation warning will be printed to stderr by
339 the ctm command, but the functionality will remain in base for all
343 The stable/12 branch has been created in subversion from head
347 Ports for the DRM modules have been simplified. Now, amd64 users should
348 just install the drm-kmod port. All others should install
351 Graphics hardware that's newer than about 2010 usually works with
352 drm-kmod. For hardware older than 2013, however, some users will need
353 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
354 than 2008 usually only works in drm-legacy-kmod. The graphics team can
355 only commit to hardware made since 2013 due to the complexity of the
356 market and difficulty to test all the older cards effectively. If you
357 have hardware supported by drm-kmod, you are strongly encouraged to use
358 that as you will get better support.
360 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
361 elsewhere, the drm and drm2 modules will be eliminated from the src base
362 soon (with a limited exception for arm). Please update to the package asap
363 and report any issues to x11@freebsd.org.
365 Generally, anybody using the drm*-kmod packages should add
366 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
367 cross-threading surprises, especially with automatic driver
368 loading from X11 startup. These will become the defaults in 13-current
372 The ixlv(4) driver has been renamed to iavf(4). As a consequence,
373 custom kernel and module loading configuration files must be updated
374 accordingly. Moreover, interfaces previous presented as ixlvN to the
375 system are now exposed as iavfN and network configuration files must
376 be adjusted as necessary.
379 OpenSSL has been updated to version 1.1.1. This update included
380 additional various API changes througout the base system. It is
381 important to rebuild third-party software after upgrading. The value
382 of __FreeBSD_version has been bumped accordingly.
385 The legacy DRM modules and drivers have now been added to the loader's
386 module blacklist, in favor of loading them with kld_list in rc.conf(5).
387 The module blacklist may be overridden with the loader.conf(5)
388 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
392 The cam(4) based nda(4) driver will be used over nvd(4) by default on
393 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
394 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
395 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
399 Reproducible build mode is now on by default, in preparation for
400 FreeBSD 12.0. This eliminates build metadata such as the user,
401 host, and time from the kernel (and uname), unless the working tree
402 corresponds to a modified checkout from a version control system.
403 The previous behavior can be obtained by setting the /etc/src.conf
404 knob WITHOUT_REPRODUCIBLE_BUILD.
407 The Yarrow CSPRNG has been removed from the kernel as it has not been
408 supported by its designers since at least 2003. Fortuna has been the
409 default since FreeBSD-11.
412 devctl freeze/thaw have gone into the tree, the rc scripts have been
413 updated to use them and devmatch has been changed. You should update
414 kernel, userland and rc scripts all at the same time.
417 The default interpreter has been switched from 4th to Lua.
418 LOADER_DEFAULT_INTERP, documented in build(7), will override the default
419 interpreter. If you have custom FORTH code you will need to set
420 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
421 src.conf for the build. This will create default hard links between
422 loader and loader_4th instead of loader and loader_lua, the new default.
423 If you are using UEFI it will create the proper hard link to loader.efi.
425 bhyve uses userboot.so. It remains 4th-only until some issues are solved
426 regarding coexisting with multiple versions of FreeBSD are resolved.
429 ls(1) now respects the COLORTERM environment variable used in other
430 systems and software to indicate that a colored terminal is both
431 supported and desired. If ls(1) is suddenly emitting colors, they may
432 be disabled again by either removing the unwanted COLORTERM from your
433 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
434 may not be observed in a future release.
437 The default pager for most commands has been changed to "less". To
438 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
442 The jedec_ts(4) driver has been removed. A superset of its functionality
443 is available in the jedec_dimm(4) driver, and the manpage for that
444 driver includes migration instructions. If you have "device jedec_ts"
445 in your kernel configuration file, it must be removed.
448 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
449 This should have no effect if the kernel is booted via BIOS/legacy boot.
450 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
451 has a buggy firmware that prevents a successful boot due to use of
455 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
456 support has been removed from the tree. These ports were
457 obsolete and/or known to be broken for many years.
460 loader.efi has been augmented to participate more fully in the
461 UEFI boot manager protocol. loader.efi will now look at the
462 BootXXXX environment variable to determine if a specific kernel
463 or root partition was specified. XXXX is derived from BootCurrent.
464 efibootmgr(8) manages these standard UEFI variables.
467 zfsloader's functionality has now been folded into loader.
468 zfsloader is no longer necessary once you've updated your
469 boot blocks. For a transition period, we will install a
470 hardlink for zfsloader to loader to allow a smooth transition
471 until the boot blocks can be updated (hard link because old
472 zfs boot blocks don't understand symlinks).
475 ARM64 now have efifb support, if you want to have serial console
476 on your arm64 board when an screen is connected and the bootloader
477 setup a frambuffer for us to use, just add :
481 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
482 an screen connected as the firmware will setup a framebuffer are that
483 u-boot will expose as an EFI framebuffer.
486 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
487 or take steps to update /etc/passwd before doing installworld on
488 existing systems. Do not skip the "mergemaster -Fp" step before
489 installworld, as described in the update procedures near the bottom
490 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
491 if the new mac_ntpd(4) policy is available, unless ntpd_flags or
492 the ntp config file contain options that change file/dir locations.
493 When such options (e.g., "statsdir" or "crypto") are used, ntpd can
494 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
495 taking steps to ensure that all required files/dirs are accessible
499 Big endian arm support has been removed.
502 The static environment setup in kernel configs is no longer mutually
503 exclusive with the loader(8) environment by default. In order to
504 restore the previous default behavior of disabling the loader(8)
505 environment if a static environment is present, you must specify
506 loader_env.disabled=1 in the static environment.
509 The ABI of syscalls used by management tools like sockstat and
510 netstat has been broken to allow 32-bit binaries to work on
511 64-bit kernels without modification. These programs will need
512 to match the kernel in order to function. External programs may
513 require minor modifications to accommodate a change of type in
514 structures from pointers to 64-bit virtual addresses.
517 On i386 and amd64 atomics are now inlined. Out of tree modules using
518 atomics will need to be rebuilt.
521 The '%I' format in the kern.corefile sysctl limits the number of
522 core files that a process can generate to the number stored in the
523 debug.ncores sysctl. The '%I' format is replaced by the single digit
524 index. Previously, if all indexes were taken the kernel would overwrite
525 only a core file with the highest index in a filename.
526 Currently the system will create a new core file if there is a free
527 index or if all slots are taken it will overwrite the oldest one.
530 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
531 6.0.1. Please see the 20141231 entry below for information about
532 prerequisites and upgrading, if you are not already using clang 3.5.0
536 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
537 needed to be changed to work with it. This change was made with r335763
538 and requires a mergemaster / etcupdate / etc to update the installed file.
541 r334930 changed the interface between the NFS modules, so they all
542 need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
545 As of r334391 lld is the default amd64 system linker; it is installed
546 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
550 The kernel / userland interface for devinfo changed, so you'll
551 need a new kernel and userland as a pair for it to work (rebuilding
552 lib/libdevinfo is all that's required). devinfo and devmatch will
553 not work, but everything else will when there's a mismatch.
556 The on-disk format for hwpmc callchain records has changed to include
557 threadid corresponding to a given record. This changes the field offsets
558 and thus requires that libpmcstat be rebuilt before using a kernel
562 The vxge(4) driver has been removed. This driver was introduced into
563 HEAD one week before the Exar left the Ethernet market and is not
564 known to be used. If you have device vxge in your kernel config file
568 The amd64 kernel now requires a ld that supports ifunc to produce a
569 working kernel, either lld or a newer binutils. lld is built by default
570 on amd64, and the 'buildkernel' target uses it automatically. However,
571 it is not the default linker, so building the kernel the traditional
572 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
573 binutils port/package). lld will soon be default, and this requirement
576 NOTE: As of r334391 lld is the default system linker on amd64, and no
577 workaround is necessary.
580 The nxge(4) driver has been removed. This driver was for PCI-X 10g
581 cards made by s2io/Neterion. The company was aquired by Exar and
582 no longer sells or supports Ethernet products. If you have device
583 nxge in your kernel config file it must be removed.
586 The tz database (tzdb) has been updated to 2018e. This version more
587 correctly models time stamps in time zones with negative DST such as
588 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
589 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
590 time zone abbreviations and the tm_isdst flag.
593 The ixgb(4) driver has been removed. This driver was for an early and
594 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
595 quickly shifted to the long lived ixgbe family. If you have device
596 ixgb in your kernel config file it must be removed.
599 The lmc(4) driver has been removed. This was a WAN interface
600 card that was already reportedly rare in 2003, and had an ambiguous
601 license. If you have device lmc in your kernel config file it must
605 Support for Arcnet networks has been removed. If you have device
606 arcnet or device cm in your kernel config file they must be
610 Support for FDDI networks has been removed. If you have device
611 fddi or device fpa in your kernel config file they must be
615 In addition to supporting RFC 3164 formatted messages, the
616 syslogd(8) service is now capable of parsing RFC 5424 formatted
617 log messages. The main benefit of using RFC 5424 is that clients
618 may now send log messages with timestamps containing year numbers,
619 microseconds and time zone offsets.
621 Similarly, the syslog(3) C library function has been altered to
622 send RFC 5424 formatted messages to the local system logging
623 daemon. On systems using syslogd(8), this change should have no
624 negative impact, as long as syslogd(8) and the C library are
625 updated at the same time. On systems using a different system
626 logging daemon, it may be necessary to make configuration
627 adjustments, depending on the software used.
629 When using syslog-ng, add the 'syslog-protocol' flag to local
630 input sources to enable parsing of RFC 5424 formatted messages:
633 unix-dgram("/var/run/log" flags(syslog-protocol));
636 When using rsyslog, disable the 'SysSock.UseSpecialParser' option
637 of the 'imuxsock' module to let messages be processed by the
638 regular RFC 3164/5424 parsing pipeline:
640 module(load="imuxsock" SysSock.UseSpecialParser="off")
642 Do note that these changes only affect communication between local
643 applications and syslogd(8). The format that syslogd(8) uses to
644 store messages on disk or forward messages to other systems
645 remains unchanged. syslogd(8) still uses RFC 3164 for these
646 purposes. Options to customize this behaviour will be added in the
647 future. Utilities that process log files stored in /var/log are
648 thus expected to continue to function as before.
650 __FreeBSD_version has been incremented to 1200061 to denote this
654 Support for token ring networks has been removed. If you
655 have "device token" in your kernel config you should remove
656 it. No device drivers supported token ring.
659 makefs was modified to be able to tag ISO9660 El Torito boot catalog
660 entries as EFI instead of overloading the i386 tag as done previously.
661 The amd64 mkisoimages.sh script used to build amd64 ISO images for
662 release was updated to use this. This may mean that makefs must be
663 updated before "make cdrom" can be run in the release directory. This
664 should be as simple as:
666 $ cd $SRCDIR/usr.sbin/makefs
667 $ make depend all install
670 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
671 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
672 Co-existance for the transition period will come shortly. Booting is a
673 complex environment and test coverage for Lua-enabled loaders has been
674 thin, so it would be prudent to assume it might not work and make
675 provisions for backup boot methods.
678 devmatch functionality has been turned on in devd. It will automatically
679 load drivers for unattached devices. This may cause unexpected drivers to
680 be loaded. Please report any problems to current@ and imp@freebsd.org.
683 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
684 6.0.0. Please see the 20141231 entry below for information about
685 prerequisites and upgrading, if you are not already using clang 3.5.0
689 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
690 This means it is used to link the kernel and userland libraries and
691 executables, but is not yet installed as /usr/bin/ld by default.
693 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
694 WITHOUT_LLD_BOOTSTRAP=yes
697 On i386, pmtimer has been removed. Its functionality has been folded
698 into apm. It was a no-op on ACPI in current for a while now (but was still
699 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it
700 from kernel config files.
703 The use of RSS hash from the network card aka flowid has been
704 disabled by default for lagg(4) as it's currently incompatible with
705 the lacp and loadbalance protocols.
707 This can be re-enabled by setting the following in loader.conf:
708 net.link.lagg.default_use_flowid="1"
711 The SW_WATCHDOG option is no longer necessary to enable the
712 hardclock-based software watchdog if no hardware watchdog is
713 configured. As before, SW_WATCHDOG will cause the software
714 watchdog to be enabled even if a hardware watchdog is configured.
717 r326887 fixes the issue described in the 20171214 UPDATING entry.
718 r326888 flips the switch back to building GELI support always.
721 r362593 broke ZFS + GELI support for reasons unknown. However,
722 it also broke ZFS support generally, so GELI has been turned off
723 by default as the lesser evil in r326857. If you boot off ZFS and/or
724 GELI, it might not be a good time to update.
727 PowerPC users must update loader(8) by rebuilding world before
728 installing a new kernel, as the protocol connecting them has
729 changed. Without the update, loader metadata will not be passed
730 successfully to the kernel and users will have to enter their
731 root partition at the kernel mountroot prompt to continue booting.
732 Newer versions of loader can boot old kernels without issue.
735 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
736 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
737 to WITH/OUT_LOADER_GELI.
740 The naive and non-compliant support of posix_fallocate(2) in ZFS
741 has been removed as of r325320. The system call now returns EINVAL
742 when used on a ZFS file. Although the new behavior complies with the
743 standard, some consumers are not prepared to cope with it.
744 One known victim is lld prior to r325420.
747 Building in a FreeBSD src checkout will automatically create object
748 directories now rather than store files in the current directory if
749 'make obj' was not ran. Calling 'make obj' is no longer necessary.
750 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
751 /etc/src-env.conf (not /etc/src.conf), or passing the option in the
755 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
756 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
757 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
758 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
759 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
760 The UNIFIED_OBJDIR option is a transitional feature that will be
761 removed for 12.0 release; please migrate to the new format for any
762 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
763 than hardcoding paths.
766 The native-xtools target no longer installs the files by default to the
767 OBJDIR. Use the native-xtools-install target with a DESTDIR to install
768 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
771 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
772 options are changing from controlling the build if defined / undefined
773 to controlling the build with explicit 'yes' or 'no' values. They will
774 shift to WITH/WITHOUT options to match other options in the system.
777 libstand has turned into a private library for sys/boot use only.
778 It is no longer supported as a public interface outside of sys/boot.
781 The arm port has split armv6 into armv6 and armv7. armv7 is now
782 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
783 and are running a kernel from before r324363, you will need to add
784 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
787 When building multiple kernels using KERNCONF, non-existent KERNCONF
788 files will produce an error and buildkernel will fail. Previously
789 missing KERNCONF files silently failed giving no indication as to
790 why, only to subsequently discover during installkernel that the
791 desired kernel was never built in the first place.
794 The default serial number format for CTL LUNs has changed. This will
795 affect users who use /dev/diskid/* device nodes, or whose FibreChannel
796 or iSCSI clients care about their LUNs' serial numbers. Users who
797 require serial number stability should hardcode serial numbers in
801 For 32-bit arm compiled for hard-float support, soft-floating point
802 binaries now always get their shared libraries from
803 LD_SOFT_LIBRARY_PATH (in the past, this was only used if
804 /usr/libsoft also existed). Only users with a hard-float ld.so, but
805 soft-float everything else should be affected.
808 The geli password typed at boot is now hidden. To restore the previous
809 behavior, see geli(8) for configuration options.
812 Move PMTUD blackhole counters to TCPSTATS and remove them from bare
813 sysctl values. Minor nit, but requires a rebuild of both world/kernel
817 "make check" behavior (made in ^/head@r295380) has been changed to
818 execute from a limited sandbox, as opposed to executing from
822 - The "beforecheck" and "aftercheck" targets are now specified.
823 - ${CHECKDIR} (added in commit noted above) has been removed.
824 - Legacy behavior can be enabled by setting
825 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
827 If the limited sandbox mode is enabled, "make check" will execute
828 "make distribution", then install, execute the tests, and clean up the
829 sandbox if successful.
831 The "make distribution" and "make install" targets are typically run as
832 root to set appropriate permissions and ownership at installation time.
833 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
834 environment if executing "make check" with limited sandbox mode using
835 an unprivileged user.
838 Since the switch to GPT disk labels, fsck for UFS/FFS has been
839 unable to automatically find alternate superblocks. As of r322297,
840 the information needed to find alternate superblocks has been
841 moved to the end of the area reserved for the boot block.
842 Filesystems created with a newfs of this vintage or later
843 will create the recovery information. If you have a filesystem
844 created prior to this change and wish to have a recovery block
845 created for your filesystem, you can do so by running fsck in
846 foreground mode (i.e., do not use the -p or -y options). As it
847 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
848 to which you should answer yes.
851 As of r321665, an NFSv4 server configuration that services
852 Kerberos mounts or clients that do not support the uid/gid in
853 owner/owner_group string capability, must explicitly enable
854 the nfsuserd daemon by adding nfsuserd_enable="YES" to the
855 machine's /etc/rc.conf file.
858 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
859 Please see the 20141231 entry below for information about prerequisites
860 and upgrading, if you are not already using clang 3.5.0 or higher.
863 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
864 r-commands (rlogin, rsh, etc.) to be built with the base system.
867 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
868 a very major ABI incompatible change, so users of FreeBSD/powerpc must
869 be careful when performing source upgrades. It is best to run
870 'make installworld' from an alternate root system, either a live
871 CD/memory stick, or a temporary root partition. Additionally, all ports
872 must be recompiled. powerpc64 is largely unaffected, except in the case
873 of 32-bit compatibility. All 32-bit binaries will be affected.
876 Forward compatibility for the "ino64" project have been committed. This
877 will allow most new binaries to run on older kernels in a limited
878 fashion. This prevents many of the common foot-shooting actions in the
879 upgrade as well as the limited ability to roll back the kernel across
880 the ino64 upgrade. Complicated use cases may not work properly, though
881 enough simpler ones work to allow recovery in most situations.
884 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
885 if you require the GPL compiler.
888 The internal ABI used for communication between the NFS kernel modules
889 was changed by r320085, so __FreeBSD_version was bumped to
890 ensure all the NFS related modules are updated together.
893 The ABI of struct event was changed by extending the data
894 member to 64bit and adding ext fields. For upgrade, same
895 precautions as for the entry 20170523 "ino64" must be
899 The GNU roff toolchain has been removed from base. To render manpages
900 which are not supported by mandoc(1), man(1) can fallback on GNU roff
901 from ports (and recommends to install it).
902 To render roff(7) documents, consider using GNU roff from ports or the
903 heirloom doctools roff toolchain from ports via pkg install groff or
904 via pkg install heirloom-doctools.
907 The ath(4) and ath_hal(4) modules now build piecemeal to allow for
908 smaller runtime footprint builds. This is useful for embedded systems
909 which only require one chipset support.
911 If you load it as a module, make sure this is in /boot/loader.conf:
915 This will load the HAL, all chip/RF backends and if_ath_pci.
916 If you have if_ath_pci in /boot/loader.conf, ensure it is after
917 if_ath or it will not load any HAL chipset support.
919 If you want to selectively load things (eg on ye cheape ARM/MIPS
920 platforms where RAM is at a premium) you should:
923 * load the chip modules in question
924 * load ath_rate, ath_dfs
926 * load if_ath_pci and/or if_ath_ahb depending upon your particular
927 bus bind type - this is where probe/attach is done.
929 For further comments/feedback, poke adrian@ .
932 The "ino64" 64-bit inode project has been committed, which extends
933 a number of types to 64 bits. Upgrading in place requires care and
934 adherence to the documented upgrade procedure.
936 If using a custom kernel configuration ensure that the
937 COMPAT_FREEBSD11 option is included (as during the upgrade the
938 system will be running the ino64 kernel with the existing world).
940 For the safest in-place upgrade begin by removing previous build
941 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the
942 full procedure documented below under the heading "To rebuild
943 everything and install it on the current system." Specifically,
944 a reboot is required after installing the new kernel before
948 The NATM framework including the en(4), fatm(4), hatm(4), and
949 patm(4) devices has been removed. Consumers should plan a
950 migration before the end-of-life date for FreeBSD 11.
953 GNU diff has been replaced by a BSD licensed diff. Some features of GNU
954 diff has not been implemented, if those are needed a newer version of
955 GNU diff is available via the diffutils package under the gdiff name.
958 As of r316810 for ipfilter, keep frags is no longer assumed when
959 keep state is specified in a rule. r316810 aligns ipfilter with
960 documentation in man pages separating keep frags from keep state.
961 This allows keep state to be specified without forcing keep frags
962 and allows keep frags to be specified independently of keep state.
963 To maintain previous behaviour, also specify keep frags with
964 keep state (as documented in ipf.conf.5).
967 arm64 builds now use the base system LLD 4.0.0 linker by default,
968 instead of requiring that the aarch64-binutils port or package be
969 installed. To continue using aarch64-binutils, set
970 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
973 The UDP optimization in entry 20160818 that added the sysctl
974 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
975 packets will no longer be treated as L3 broadcast packets.
978 Binds and sends to the loopback addresses, IPv6 and IPv4, will now
979 use any explicitly assigned loopback address available in the jail
980 instead of using the first assigned address of the jail.
983 The ctl.ko module no longer implements the iSCSI target frontend:
984 cfiscsi.ko does instead.
986 If building cfiscsi.ko as a kernel module, the module can be loaded
987 via one of the following methods:
988 - `cfiscsi_load="YES"` in loader.conf(5).
989 - Add `cfiscsi` to `$kld_list` in rc.conf(5).
990 - ctladm(8)/ctld(8), when compiled with iSCSI support
991 (`WITH_ISCSI=yes` in src.conf(5))
993 Please see cfiscsi(4) for more details.
996 The mmcsd.ko module now additionally depends on geom_flashmap.ko.
997 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
998 same source (previously, the dependency of mmcsd.ko on mmc.ko was
999 missing, but mmcsd.ko now will refuse to load if it is incompatible
1003 The syntax of ipfw(8) named states was changed to avoid ambiguity.
1004 If you have used named states in the firewall rules, you need to modify
1005 them after installworld and before rebooting. Now named states must
1006 be prefixed with colon.
1009 The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1010 removed as the userland we provide cannot use them. The KMS version
1011 (sys/dev/drm2) supports the same hardware.
1014 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
1015 Please see the 20141231 entry below for information about prerequisites
1016 and upgrading, if you are not already using clang 3.5.0 or higher.
1019 The code that provides support for ZFS .zfs/ directory functionality
1020 has been reimplemented. It's not possible now to create a snapshot
1021 by mkdir under .zfs/snapshot/. That should be the only user visible
1025 EISA bus support has been removed. The WITH_EISA option is no longer
1029 MCA bus support has been removed.
1032 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1033 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
1036 The EM_MULTIQUEUE kernel configuration option is deprecated now that
1037 the em(4) driver conforms to iflib specifications.
1040 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1041 IFLIB. If you have a custom kernel configuration that excludes em(4)
1042 but you use igb(4), you need to re-add em(4) to your custom configuration.
1045 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
1046 Please see the 20141231 entry below for information about prerequisites
1047 and upgrading, if you are not already using clang 3.5.0 or higher.
1050 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
1051 Please see the 20141231 entry below for information about prerequisites
1052 and upgrading, if you are not already using clang 3.5.0 or higher.
1055 The layout of the pmap structure has changed for powerpc to put the pmap
1056 statistics at the front for all CPU variations. libkvm(3) and all tools
1057 that link against it need to be recompiled.
1060 isl(4) and cyapa(4) drivers now require a new driver,
1061 chromebook_platform(4), to work properly on Chromebook-class hardware.
1062 On other types of hardware the drivers may need to be configured using
1063 device hints. Please see the corresponding manual pages for details.
1066 The urtwn(4) driver was merged into rtwn(4) and now consists of
1067 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
1069 Also, firmware for RTL8188CE was renamed due to possible name
1070 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
1073 GNU rcs has been removed from base. It is available as packages:
1074 - rcs: Latest GPLv3 GNU rcs version.
1075 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
1079 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1080 modules now requires that the kernel configuration contain the
1081 TCP_HHOOK option. (This option is included in the GENERIC kernel.)
1084 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
1085 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
1088 Relocatable object files with the extension of .So have been renamed
1089 to use an extension of .pico instead. The purpose of this change is
1090 to avoid a name clash with shared libraries on case-insensitive file
1091 systems. On those file systems, foo.So is the same file as foo.so.
1094 GNU rcs has been turned off by default. It can (temporarily) be built
1095 again by adding WITH_RCS knob in src.conf.
1096 Otherwise, GNU rcs is available from packages:
1097 - rcs: Latest GPLv3 GNU rcs version.
1098 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
1101 The backup_uses_rcs functionality has been removed from rc.subr.
1104 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
1105 two separate components, QUEUE_MACRO_DEBUG_TRACE and
1106 QUEUE_MACRO_DEBUG_TRASH. Define both for the original
1107 QUEUE_MACRO_DEBUG behavior.
1110 r304787 changed some ioctl interfaces between the iSCSI userspace
1111 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
1112 rebuilt to work with new kernels. __FreeBSD_version has been bumped
1116 The UDP receive code has been updated to only treat incoming UDP
1117 packets that were addressed to an L2 broadcast address as L3
1118 broadcast packets. It is not expected that this will affect any
1119 standards-conforming UDP application. The new behaviour can be
1120 disabled by setting the sysctl net.inet.udp.require_l2_bcast to
1124 Remove the openbsd_poll system call.
1125 __FreeBSD_version has been bumped because of this.
1128 The stable/11 branch has been created from head@r302406.
1131 The libc stub for the pipe(2) system call has been replaced with
1132 a wrapper that calls the pipe2(2) system call and the pipe(2)
1133 system call is now only implemented by the kernels that include
1134 "options COMPAT_FREEBSD10" in their config file (this is the
1135 default). Users should ensure that this option is enabled in
1136 their kernel or upgrade userspace to r302092 before upgrading their
1140 CAM will now strip leading spaces from SCSI disks' serial numbers.
1141 This will affect users who create UFS filesystems on SCSI disks using
1142 those disk's diskid device nodes. For example, if /etc/fstab
1143 previously contained a line like
1144 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1145 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
1146 transforms like gmirror may also be affected. ZFS users should
1150 The bitstring(3) API has been updated with new functionality and
1151 improved performance. But it is binary-incompatible with the old API.
1152 Objects built with the new headers may not be linked against objects
1153 built with the old headers.
1156 The brk and sbrk functions have been removed from libc on arm64.
1157 Binutils from ports has been updated to not link to these
1158 functions and should be updated to the latest version before
1159 installing a new libc.
1162 The armv6 port now defaults to hard float ABI. Limited support
1163 for running both hardfloat and soft float on the same system
1164 is available using the libraries installed with -DWITH_LIBSOFT.
1165 This has only been tested as an upgrade path for installworld
1166 and packages may fail or need manual intervention to run. New
1167 packages will be needed.
1169 To update an existing self-hosted armv6hf system, you must add
1170 TARGET_ARCH=armv6 on the make command line for both the build
1171 and the install steps.
1174 Kernel modules compiled outside of a kernel build now default to
1175 installing to /boot/modules instead of /boot/kernel. Many kernel
1176 modules built this way (such as those in ports) already overrode
1177 KMODDIR explicitly to install into /boot/modules. However,
1178 manually building and installing a module from /sys/modules will
1179 now install to /boot/modules instead of /boot/kernel.
1182 The CAM I/O scheduler has been committed to the kernel. There should be
1183 no user visible impact. This does enable NCQ Trim on ada SSDs. While the
1184 list of known rogues that claim support for this but actually corrupt
1185 data is believed to be complete, be on the lookout for data
1186 corruption. The known rogue list is believed to be complete:
1188 o Crucial MX100, M550 drives with MU01 firmware.
1189 o Micron M510 and M550 drives with MU01 firmware.
1190 o Micron M500 prior to MU07 firmware
1191 o Samsung 830, 840, and 850 all firmwares
1192 o FCCT M500 all firmwares
1194 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1195 with working NCQ TRIM. For Micron branded drives, see your sales rep for
1196 updated firmware. Black listed drives will work correctly because these
1197 drives work correctly so long as no NCQ TRIMs are sent to them. Given
1198 this list is the same as found in Linux, it's believed there are no
1199 other rogues in the market place. All other models from the above
1202 To be safe, if you are at all concerned, you can quirk each of your
1203 drives to prevent NCQ from being sent by setting:
1204 kern.cam.ada.X.quirks="0x2"
1205 in loader.conf. If the drive requires the 4k sector quirk, set the
1206 quirks entry to 0x3.
1209 The FAST_DEPEND build option has been removed and its functionality is
1210 now the one true way. The old mkdep(1) style of 'make depend' has
1211 been removed. See 20160311 for further details.
1214 Resource range types have grown from unsigned long to uintmax_t. All
1215 drivers, and anything using libdevinfo, need to be recompiled.
1218 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1219 builds. It no longer runs mkdep(1) during 'make depend', and the
1220 'make depend' stage can safely be skipped now as it is auto ran
1221 when building 'make all' and will generate all SRCS and DPSRCS before
1222 building anything else. Dependencies are gathered at compile time with
1223 -MF flags kept in separate .depend files per object file. Users should
1224 run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1225 stale .depend files.
1228 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1229 kernel modules. Therefore, if you load any kernel modules at boot time,
1230 please install the boot loaders after you install the kernel, but before
1234 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1235 make installkernel KERNCONF=YOUR_KERNEL_HERE
1236 make -C sys/boot install
1237 <reboot in single user>
1239 Then follow the usual steps, described in the General Notes section,
1243 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
1244 see the 20141231 entry below for information about prerequisites and
1245 upgrading, if you are not already using clang 3.5.0 or higher.
1248 The AIO subsystem is now a standard part of the kernel. The
1249 VFS_AIO kernel option and aio.ko kernel module have been removed.
1250 Due to stability concerns, asynchronous I/O requests are only
1251 permitted on sockets and raw disks by default. To enable
1252 asynchronous I/O requests on all file types, set the
1253 vfs.aio.enable_unsafe sysctl to a non-zero value.
1256 The ELF object manipulation tool objcopy is now provided by the
1257 ELF Tool Chain project rather than by GNU binutils. It should be a
1258 drop-in replacement, with the addition of arm64 support. The
1259 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1260 to obtain the GNU version if necessary.
1263 Building ZFS pools on top of zvols is prohibited by default. That
1264 feature has never worked safely; it's always been prone to deadlocks.
1265 Using a zvol as the backing store for a VM guest's virtual disk will
1266 still work, even if the guest is using ZFS. Legacy behavior can be
1267 restored by setting vfs.zfs.vol.recursive=1.
1270 The NONE and HPN patches has been removed from OpenSSH. They are
1271 still available in the security/openssh-portable port.
1274 With the addition of ypldap(8), a new _ypldap user is now required
1275 during installworld. "mergemaster -p" can be used to add the user
1276 prior to installworld, as documented in the handbook.
1279 The tftp loader (pxeboot) now uses the option root-path directive. As a
1280 consequence it no longer looks for a pxeboot.4th file on the tftp
1281 server. Instead it uses the regular /boot infrastructure as with the
1285 The code to start recording plug and play data into the modules has
1286 been committed. While the old tools will properly build a new kernel,
1287 a number of warnings about "unknown metadata record 4" will be produced
1288 for an older kldxref. To avoid such warnings, make sure to rebuild
1289 the kernel toolchain (or world). Make sure that you have r292078 or
1290 later when trying to build 292077 or later before rebuilding.
1293 Debug data files are now built by default with 'make buildworld' and
1294 installed with 'make installworld'. This facilitates debugging but
1295 requires more disk space both during the build and for the installed
1296 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1300 r291527 changed the internal interface between the nfsd.ko and
1301 nfscommon.ko modules. As such, they must both be upgraded to-gether.
1302 __FreeBSD_version has been bumped because of this.
1305 Add support for unicode collation strings leads to a change of
1306 order of files listed by ls(1) for example. To get back to the old
1307 behaviour, set LC_COLLATE environment variable to "C".
1309 Databases administrators will need to reindex their databases given
1310 collation results will be different.
1312 Due to a bug in install(1) it is recommended to remove the ancient
1313 locales before running make installworld.
1315 rm -rf /usr/share/locale/*
1318 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
1319 libcrypto.so.7 or libssl.so.7 must be recompiled.
1322 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1323 Kernel modules isp_2400_multi and isp_2500_multi were removed and
1324 should be replaced with isp_2400 and isp_2500 modules respectively.
1327 The build previously allowed using 'make -n' to not recurse into
1328 sub-directories while showing what commands would be executed, and
1329 'make -n -n' to recursively show commands. Now 'make -n' will recurse
1330 and 'make -N' will not.
1333 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1334 and etcupdate will now use this file. A custom sendmail.cf is now
1335 updated via this mechanism rather than via installworld. If you had
1336 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1337 want to remove the exclusion or change it to "always install".
1338 /etc/mail/sendmail.cf is now managed the same way regardless of
1339 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
1340 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1343 Compatibility shims for legacy ATA device names have been removed.
1344 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
1345 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
1346 environment variables, /dev/ad* and /dev/ar* symbolic links.
1349 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
1350 Please see the 20141231 entry below for information about prerequisites
1351 and upgrading, if you are not already using clang 3.5.0 or higher.
1354 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
1355 and renamed from .symbols to .debug. This reduces the size requirements
1356 on the boot partition or file system and provides consistency with
1357 userland debug files.
1359 When using the supported kernel installation method the
1360 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
1361 as is done with /boot/kernel.
1363 Developers wishing to maintain the historical behavior of installing
1364 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
1367 The wireless drivers had undergone changes that remove the 'parent
1368 interface' from the ifconfig -l output. The rc.d network scripts
1369 used to check presence of a parent interface in the list, so old
1370 scripts would fail to start wireless networking. Thus, etcupdate(3)
1371 or mergemaster(8) run is required after kernel update, to update your
1372 rc.d scripts in /etc.
1375 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
1376 These configurations are now automatically interpreted as
1377 'scrub fragment reassemble'.
1380 Kernel-loadable modules for the random(4) device are back. To use
1381 them, the kernel must have
1384 options RANDOM_LOADABLE
1386 kldload(8) can then be used to load random_fortuna.ko
1387 or random_yarrow.ko. Please note that due to the indirect
1388 function calls that the loadable modules need to provide,
1389 the build-in variants will be slightly more efficient.
1391 The random(4) kernel option RANDOM_DUMMY has been retired due to
1392 unpopularity. It was not all that useful anyway.
1395 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
1396 Control over building the ELF Tool Chain tools is now provided by
1397 the WITHOUT_TOOLCHAIN knob.
1400 The polarity of Pulse Per Second (PPS) capture events with the
1401 uart(4) driver has been corrected. Prior to this change the PPS
1402 "assert" event corresponded to the trailing edge of a positive PPS
1403 pulse and the "clear" event was the leading edge of the next pulse.
1405 As the width of a PPS pulse in a typical GPS receiver is on the
1406 order of 1 millisecond, most users will not notice any significant
1407 difference with this change.
1409 Anyone who has compensated for the historical polarity reversal by
1410 configuring a negative offset equal to the pulse width will need to
1411 remove that workaround.
1414 The default group assigned to /dev/dri entries has been changed
1415 from 'wheel' to 'video' with the id of '44'. If you want to have
1416 access to the dri devices please add yourself to the video group
1419 # pw groupmod video -m $USER
1422 The menu.rc and loader.rc files will now be replaced during
1423 upgrades. Please migrate local changes to menu.rc.local and
1424 loader.rc.local instead.
1427 GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1428 strings and strip have been removed. The src.conf(5) knob
1429 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1432 As ZFS requires more kernel stack pages than is the default on some
1433 architectures e.g. i386, it now warns if KSTACK_PAGES is less than
1434 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
1436 Please consider using 'options KSTACK_PAGES=X' where X is greater
1437 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
1440 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
1441 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1442 default, i.e., they will not contain "::". For example, instead
1443 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
1444 to have a more specific match, such as different map entries for
1445 IPv6:0:0 vs IPv6:0. This change requires that configuration
1446 data (including maps, files, classes, custom ruleset, etc.) must
1447 use the same format, so make certain such configuration data is
1448 upgrading. As a very simple check search for patterns like
1449 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
1450 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1451 the cf option UseCompressedIPv6Addresses.
1454 The default kernel entropy-processing algorithm is now
1455 Fortuna, replacing Yarrow.
1457 Assuming you have 'device random' in your kernel config
1458 file, the configurations allow a kernel option to override
1459 this default. You may choose *ONE* of:
1461 options RANDOM_YARROW # Legacy /dev/random algorithm.
1462 options RANDOM_DUMMY # Blocking-only driver.
1464 If you have neither, you get Fortuna. For most people,
1465 read no further, Fortuna will give a /dev/random that works
1466 like it always used to, and the difference will be irrelevant.
1468 If you remove 'device random', you get *NO* kernel-processed
1469 entropy at all. This may be acceptable to folks building
1470 embedded systems, but has complications. Carry on reading,
1471 and it is assumed you know what you need.
1473 *PLEASE* read random(4) and random(9) if you are in the
1474 habit of tweaking kernel configs, and/or if you are a member
1475 of the embedded community, wanting specific and not-usual
1476 behaviour from your security subsystems.
1478 NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1479 random', you will NOT have a functioning /dev/random, and
1480 many cryptographic features will not work, including SSH.
1481 You may also find strange behaviour from the random(3) set
1482 of library functions, in particular sranddev(3), srandomdev(3)
1483 and arc4random(3). The reason for this is that the KERN_ARND
1484 sysctl only returns entropy if it thinks it has some to
1485 share, and with RANDOM_DUMMY or no 'device random' this
1489 An additional fix for the issue described in the 20150614 sendmail
1490 entry below has been committed in revision 284717.
1493 FreeBSD's old make (fmake) has been removed from the system. It is
1494 available as the devel/fmake port or via pkg install fmake.
1497 The fix for the issue described in the 20150614 sendmail entry
1498 below has been committed in revision 284436. The work
1499 around described in that entry is no longer needed unless the
1500 default setting is overridden by a confDH_PARAMETERS configuration
1501 setting of '5' or pointing to a 512 bit DH parameter file.
1504 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
1505 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
1506 and devel/kyua to version 0.20+ and adjust any calling code to work
1507 with Kyuafile and kyua.
1510 The import of openssl to address the FreeBSD-SA-15:10.openssl
1511 security advisory includes a change which rejects handshakes
1512 with DH parameters below 768 bits. sendmail releases prior
1513 to 8.15.2 (not yet released), defaulted to a 512 bit
1514 DH parameter setting for client connections. To work around
1515 this interoperability, sendmail can be configured to use a
1516 2048 bit DH parameter by:
1518 1. Edit /etc/mail/`hostname`.mc
1519 2. If a setting for confDH_PARAMETERS does not exist or
1520 exists and is set to a string beginning with '5',
1521 replace it with '2'.
1522 3. If a setting for confDH_PARAMETERS exists and is set to
1523 a file path, create a new file with:
1524 openssl dhparam -out /path/to/file 2048
1525 4. Rebuild the .cf file:
1526 cd /etc/mail/; make; make install
1527 5. Restart sendmail:
1528 cd /etc/mail/; make restart
1530 A sendmail patch is coming, at which time this file will be
1534 Generation of legacy formatted entries have been disabled by default
1535 in pwd_mkdb(8), as all base system consumers of the legacy formatted
1536 entries were converted to use the new format by default when the new,
1537 machine independent format have been added and supported since FreeBSD
1540 Please see the pwd_mkdb(8) manual page for further details.
1543 Clang and llvm have been upgraded to 3.6.1 release. Please see the
1544 20141231 entry below for information about prerequisites and upgrading,
1545 if you are not already using 3.5.0 or higher.
1548 TI platform code switched to using vendor DTS files and this update
1549 may break existing systems running on Beaglebone, Beaglebone Black,
1552 - dtb files should be regenerated/reinstalled. Filenames are the
1553 same but content is different now
1554 - GPIO addressing was changed, now each GPIO bank (32 pins per bank)
1555 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
1556 addressing scheme is now pin 25 on /dev/gpioc3.
1557 - Pandaboard: /etc/ttys should be updated, serial console device is
1558 now /dev/ttyu2, not /dev/ttyu0
1561 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
1562 If you need the GNU extension from groff soelim(1), install groff
1563 from package: pkg install groff, or via ports: textproc/groff.
1566 chmod, chflags, chown and chgrp now affect symlinks in -R mode as
1567 defined in symlink(7); previously symlinks were silently ignored.
1570 The const qualifier has been removed from iconv(3) to comply with
1571 POSIX. The ports tree is aware of this from r384038 onwards.
1574 Libraries specified by LIBADD in Makefiles must have a corresponding
1575 DPADD_<lib> variable to ensure correct dependencies. This is now
1576 enforced in src.libnames.mk.
1579 From legacy ata(4) driver was removed support for SATA controllers
1580 supported by more functional drivers ahci(4), siis(4) and mvs(4).
1581 Kernel modules ataahci and ataadaptec were removed completely,
1582 replaced by ahci and mvs modules respectively.
1585 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
1586 the 20141231 entry below for information about prerequisites and
1587 upgrading, if you are not already using 3.5.0 or higher.
1590 The 32-bit PowerPC kernel has been changed to a position-independent
1591 executable. This can only be booted with a version of loader(8)
1592 newer than January 31, 2015, so make sure to update both world and
1593 kernel before rebooting.
1596 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
1597 but before r278950, the RNG was not seeded properly. Immediately
1598 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
1599 ssh keys or openssl keys) that were generated w/ a kernel from that
1600 range. This does not affect programs that directly used /dev/random
1601 or /dev/urandom. All userland uses of arc4random(3) are affected.
1604 The autofs(4) ABI was changed in order to restore binary compatibility
1605 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
1606 with the new kernel.
1609 The powerpc64 kernel has been changed to a position-independent
1610 executable. This can only be booted with a new version of loader(8),
1611 so make sure to update both world and kernel before rebooting.
1614 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
1615 only release, no new features have been added. Please see the 20141231
1616 entry below for information about prerequisites and upgrading, if you
1617 are not already using 3.5.0.
1620 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
1621 taken from the ELF Tool Chain project rather than GNU binutils. They
1622 should be drop-in replacements, with the addition of arm64 support.
1623 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
1624 binutils tools, if necessary. See 20150805 for updated information.
1627 The default Unbound configuration now enables remote control
1628 using a local socket. Users who have already enabled the
1629 local_unbound service should regenerate their configuration
1630 by running "service local_unbound setup" as root.
1633 The GNU texinfo and GNU info pages have been removed.
1634 To be able to view GNU info pages please install texinfo from ports.
1637 Clang, llvm and lldb have been upgraded to 3.5.0 release.
1639 As of this release, a prerequisite for building clang, llvm and lldb is
1640 a C++11 capable compiler and C++11 standard library. This means that to
1641 be able to successfully build the cross-tools stage of buildworld, with
1642 clang as the bootstrap compiler, your system compiler or cross compiler
1643 should either be clang 3.3 or later, or gcc 4.8 or later, and your
1644 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
1647 On any standard FreeBSD 10.x or 11.x installation, where clang and
1648 libc++ are on by default (that is, on x86 or arm), this should work out
1651 On 9.x installations where clang is enabled by default, e.g. on x86 and
1652 powerpc, libc++ will not be enabled by default, so libc++ should be
1653 built (with clang) and installed first. If both clang and libc++ are
1654 missing, build clang first, then use it to build libc++.
1656 On 8.x and earlier installations, upgrade to 9.x first, and then follow
1657 the instructions for 9.x above.
1659 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
1660 default, and do not build clang.
1662 Many embedded systems are resource constrained, and will not be able to
1663 build clang in a reasonable time, or in some cases at all. In those
1664 cases, cross building bootable systems on amd64 is a workaround.
1666 This new version of clang introduces a number of new warnings, of which
1667 the following are most likely to appear:
1671 This warns in two cases, for both C and C++:
1672 * When the code is trying to take the absolute value of an unsigned
1673 quantity, which is effectively a no-op, and almost never what was
1674 intended. The code should be fixed, if at all possible. If you are
1675 sure that the unsigned quantity can be safely cast to signed, without
1676 loss of information or undefined behavior, you can add an explicit
1677 cast, or disable the warning.
1679 * When the code is trying to take an absolute value, but the called
1680 abs() variant is for the wrong type, which can lead to truncation.
1681 If you want to disable the warning instead of fixing the code, please
1682 make sure that truncation will not occur, or it might lead to unwanted
1685 -Wtautological-undefined-compare and
1686 -Wundefined-bool-conversion
1688 These warn when C++ code is trying to compare 'this' against NULL, while
1689 'this' should never be NULL in well-defined C++ code. However, there is
1690 some legacy (pre C++11) code out there, which actively abuses this
1691 feature, which was less strictly defined in previous C++ versions.
1693 Squid and openjdk do this, for example. The warning can be turned off
1694 for C++98 and earlier, but compiling the code in C++11 mode might result
1695 in unexpected behavior; for example, the parts of the program that are
1696 unreachable could be optimized away.
1699 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
1700 kernel sources have been removed. The .h files remain, since some
1701 utilities include them. This will need to be fixed later.
1702 If "mount -t oldnfs ..." is attempted, it will fail.
1703 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
1704 the utilities will report errors.
1707 The handling of LOCAL_LIB_DIRS has been altered to skip addition of
1708 directories to top level SUBDIR variable when their parent
1709 directory is included in LOCAL_DIRS. Users with build systems with
1710 such hierarchies and without SUBDIR entries in the parent
1711 directory Makefiles should add them or add the directories to
1715 faith(4) and faithd(8) have been removed from the base system. Faith
1716 has been obsolete for a very long time.
1719 vt(4), the new console driver, is enabled by default. It brings
1720 support for Unicode and double-width characters, as well as
1721 support for UEFI and integration with the KMS kernel video
1724 You may need to update your console settings in /etc/rc.conf,
1725 most probably the keymap. During boot, /etc/rc.d/syscons will
1726 indicate what you need to do.
1728 vt(4) still has issues and lacks some features compared to
1729 syscons(4). See the wiki for up-to-date information:
1730 https://wiki.freebsd.org/Newcons
1732 If you want to keep using syscons(4), you can do so by adding
1733 the following line to /boot/loader.conf:
1737 pjdfstest has been integrated into kyua as an opt-in test suite.
1738 Please see share/doc/pjdfstest/README for more details on how to
1742 gperf has been removed from the base system for architectures
1743 that use clang. Ports that require gperf will obtain it from the
1747 pjdfstest has been moved from tools/regression/pjdfstest to
1751 At svn r271982, The default linux compat kernel ABI has been adjusted
1752 to 2.6.18 in support of the linux-c6 compat ports infrastructure
1753 update. If you wish to continue using the linux-f10 compat ports,
1754 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
1755 encouraged to update their linux-compat packages to linux-c6 during
1756 their next update cycle.
1759 The ofwfb driver, used to provide a graphics console on PowerPC when
1760 using vt(4), no longer allows mmap() of all physical memory. This
1761 will prevent Xorg on PowerPC with some ATI graphics cards from
1762 initializing properly unless x11-servers/xorg-server is updated to
1766 The xdev targets have been converted to using TARGET and
1767 TARGET_ARCH instead of XDEV and XDEV_ARCH.
1770 The default unbound configuration has been modified to address
1771 issues with reverse lookups on networks that use private
1772 address ranges. If you use the local_unbound service, run
1773 "service local_unbound setup" as root to regenerate your
1774 configuration, then "service local_unbound reload" to load the
1778 The GNU texinfo and GNU info pages are not built and installed
1779 anymore, WITH_INFO knob has been added to allow to built and install
1781 UPDATE: see 20150102 entry on texinfo's removal
1784 The GNU readline library is now an INTERNALLIB - that is, it is
1785 statically linked into consumers (GDB and variants) in the base
1786 system, and the shared library is no longer installed. The
1787 devel/readline port is available for third party software that
1791 The Itanium architecture (ia64) has been removed from the list of
1792 known architectures. This is the first step in the removal of the
1796 Commit r268115 has added NFSv4.1 server support, merged from
1797 projects/nfsv4.1-server. Since this includes changes to the
1798 internal interfaces between the NFS related modules, a full
1799 build of the kernel and modules will be necessary.
1800 __FreeBSD_version has been bumped.
1803 The WITHOUT_VT_SUPPORT kernel config knob has been renamed
1804 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
1805 which differs from the behaviour controlled by this knob.)
1808 Maximal length of the serial number in CTL was increased from 16 to
1809 64 chars, that breaks ABI. All CTL-related tools, such as ctladm
1810 and ctld, need to be rebuilt to work with a new kernel.
1813 The libatf-c and libatf-c++ major versions were downgraded to 0 and
1814 1 respectively to match the upstream numbers. They were out of
1815 sync because, when they were originally added to FreeBSD, the
1816 upstream versions were not respected. These libraries are private
1817 and not yet built by default, so renumbering them should be a
1818 non-issue. However, unclean source trees will yield broken test
1819 programs once the operator executes "make delete-old-libs" after a
1820 "make installworld".
1822 Additionally, the atf-sh binary was made private by moving it into
1823 /usr/libexec/. Already-built shell test programs will keep the
1824 path to the old binary so they will break after "make delete-old"
1827 If you are using WITH_TESTS=yes (not the default), wipe the object
1828 tree and rebuild from scratch to prevent spurious test failures.
1829 This is only needed once: the misnumbered libraries and misplaced
1830 binaries have been added to OptionalObsoleteFiles.inc so they will
1831 be removed during a clean upgrade.
1834 Clang and llvm have been upgraded to 3.4.1 release.
1837 We bogusly installed src.opts.mk in /usr/share/mk. This file should
1838 be removed to avoid issues in the future (and has been added to
1842 /etc/src.conf now affects only builds of the FreeBSD src tree. In the
1843 past, it affected all builds that used the bsd.*.mk files. The old
1844 behavior was a bug, but people may have relied upon it. To get this
1845 behavior back, you can .include /etc/src.conf from /etc/make.conf
1846 (which is still global and isn't changed). This also changes the
1847 behavior of incremental builds inside the tree of individual
1848 directories. Set MAKESYSPATH to ".../share/mk" to do that.
1849 Although this has survived make universe and some upgrade scenarios,
1850 other upgrade scenarios may have broken. At least one form of
1851 temporary breakage was fixed with MAKESYSPATH settings for buildworld
1852 as well... In cases where MAKESYSPATH isn't working with this
1853 setting, you'll need to set it to the full path to your tree.
1855 One side effect of all this cleaning up is that bsd.compiler.mk
1856 is no longer implicitly included by bsd.own.mk. If you wish to
1857 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
1861 The lindev device has been removed since /dev/full has been made a
1862 standard device. __FreeBSD_version has been bumped.
1865 The knob WITHOUT_VI was added to the base system, which controls
1866 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
1867 in order to reorder files share/termcap and didn't build ex(1) as a
1868 build tool, so building/installing with WITH_VI is highly advised for
1869 build hosts for older releases.
1871 This issue has been fixed in stable/9 and stable/10 in r277022 and
1872 r276991, respectively.
1875 The YES_HESIOD knob has been removed. It has been obsolete for
1876 a decade. Please move to using WITH_HESIOD instead or your builds
1877 will silently lack HESIOD.
1880 The uart(4) driver has been changed with respect to its handling
1881 of the low-level console. Previously the uart(4) driver prevented
1882 any process from changing the baudrate or the CLOCAL and HUPCL
1883 control flags. By removing the restrictions, operators can make
1884 changes to the serial console port without having to reboot.
1885 However, when getty(8) is started on the serial device that is
1886 associated with the low-level console, a misconfigured terminal
1887 line in /etc/ttys will now have a real impact.
1888 Before upgrading the kernel, make sure that /etc/ttys has the
1889 serial console device configured as 3wire without baudrate to
1890 preserve the previous behaviour. E.g:
1891 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
1894 Support for libwrap (TCP wrappers) in rpcbind was disabled by default
1895 to improve performance. To re-enable it, if needed, run rpcbind
1896 with command line option -W.
1899 Switched back to the GPL dtc compiler due to updates in the upstream
1900 dts files not being supported by the BSDL dtc compiler. You will need
1901 to rebuild your kernel toolchain to pick up the new compiler. Core dumps
1902 may result while building dtb files during a kernel build if you fail
1903 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
1906 Clang and llvm have been upgraded to 3.4 release.
1909 The nve(4) driver has been removed. Please use the nfe(4) driver
1910 for NVIDIA nForce MCP Ethernet adapters instead.
1913 An ABI incompatibility crept into the libc++ 3.4 import in r261283.
1914 This could cause certain C++ applications using shared libraries built
1915 against the previous version of libc++ to crash. The incompatibility
1916 has now been fixed, but any C++ applications or shared libraries built
1917 between r261283 and r261801 should be recompiled.
1920 OpenSSH will now ignore errors caused by kernel lacking of Capsicum
1921 capability mode support. Please note that enabling the feature in
1922 kernel is still highly recommended.
1925 OpenSSH is now built with sandbox support, and will use sandbox as
1926 the default privilege separation method. This requires Capsicum
1927 capability mode support in kernel.
1930 The libelf and libdwarf libraries have been updated to newer
1931 versions from upstream. Shared library version numbers for
1932 these two libraries were bumped. Any ports or binaries
1933 requiring these two libraries should be recompiled.
1934 __FreeBSD_version is bumped to 1100006.
1937 If a Makefile in a tests/ directory was auto-generating a Kyuafile
1938 instead of providing an explicit one, this would prevent such
1939 Makefile from providing its own Kyuafile in the future during
1940 NO_CLEAN builds. This has been fixed in the Makefiles but manual
1941 intervention is needed to clean an objdir if you use NO_CLEAN:
1942 # find /usr/obj -name Kyuafile | xargs rm -f
1945 The behavior of gss_pseudo_random() for the krb5 mechanism
1946 has changed, for applications requesting a longer random string
1947 than produced by the underlying enctype's pseudo-random() function.
1948 In particular, the random string produced from a session key of
1949 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
1950 be different at the 17th octet and later, after this change.
1951 The counter used in the PRF+ construction is now encoded as a
1952 big-endian integer in accordance with RFC 4402.
1953 __FreeBSD_version is bumped to 1100004.
1956 The WITHOUT_ATF build knob has been removed and its functionality
1957 has been subsumed into the more generic WITHOUT_TESTS. If you were
1958 using the former to disable the build of the ATF libraries, you
1959 should change your settings to use the latter.
1962 The default version of mtree is nmtree which is obtained from
1963 NetBSD. The output is generally the same, but may vary
1964 slightly. If you found you need identical output adding
1965 "-F freebsd9" to the command line should do the trick. For the
1966 time being, the old mtree is available as fmtree.
1969 libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
1970 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
1971 1.1.4_8 and verify bsdyml not linked in, before running "make
1973 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
1975 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
1978 The stable/10 branch has been created in subversion from head
1985 Avoid using make -j when upgrading. While generally safe, there are
1986 sometimes problems using -j to upgrade. If your upgrade fails with
1987 -j, please try again without -j. From time to time in the past there
1988 have been problems using -j with buildworld and/or installworld. This
1989 is especially true when upgrading between "distant" versions (eg one
1990 that cross a major release boundary or several minor releases, or when
1991 several months have passed on the -current branch).
1993 Sometimes, obscure build problems are the result of environment
1994 poisoning. This can happen because the make utility reads its
1995 environment when searching for values for global variables. To run
1996 your build attempts in an "environmental clean room", prefix all make
1997 commands with 'env -i '. See the env(1) manual page for more details.
1999 When upgrading from one major version to another it is generally best to
2000 upgrade to the latest code in the currently installed branch first, then
2001 do an upgrade to the new branch. This is the best-tested upgrade path,
2002 and has the highest probability of being successful. Please try this
2003 approach if you encounter problems with a major version upgrade. Since
2004 the stable 4.x branch point, one has generally been able to upgrade from
2005 anywhere in the most recent stable branch to head / current (or even the
2006 last couple of stable branches). See the top of this file when there's
2009 When upgrading a live system, having a root shell around before
2010 installing anything can help undo problems. Not having a root shell
2011 around can lead to problems if pam has changed too much from your
2012 starting point to allow continued authentication after the upgrade.
2014 This file should be read as a log of events. When a later event changes
2015 information of a prior event, the prior event should not be deleted.
2016 Instead, a pointer to the entry with the new information should be
2017 placed in the old entry. Readers of this file should also sanity check
2018 older entries before relying on them blindly. Authors of new entries
2019 should write them with this in mind.
2023 When upgrading the boot ZFS pool to a new version, always follow
2026 1.) recompile and reinstall the ZFS boot loader and boot block
2027 (this is part of "make buildworld" and "make installworld")
2029 2.) update the ZFS boot block on your boot drive
2031 The following example updates the ZFS boot block on the first
2032 partition (freebsd-boot) of a GPT partitioned drive ada0:
2033 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0"
2035 Non-boot pools do not need these updates.
2039 If you are updating from a prior version of FreeBSD (even one just
2040 a few days old), you should follow this procedure. It is the most
2041 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
2043 make kernel-toolchain
2044 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
2045 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
2047 To test a kernel once
2048 ---------------------
2049 If you just want to boot a kernel once (because you are not sure
2050 if it works, or if you want to boot a known bad kernel to provide
2051 debugging information) run
2052 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
2053 nextboot -k testkernel
2055 To rebuild everything and install it on the current system.
2056 -----------------------------------------------------------
2057 # Note: sometimes if you are running current you gotta do more than
2058 # is listed here if you are upgrading from a really old current.
2060 <make sure you have good level 0 dumps>
2062 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2063 make installkernel KERNCONF=YOUR_KERNEL_HERE
2065 <reboot in single user> [3]
2072 To cross-install current onto a separate partition
2073 --------------------------------------------------
2074 # In this approach we use a separate partition to hold
2075 # current's root, 'usr', and 'var' directories. A partition
2076 # holding "/", "/usr" and "/var" should be about 2GB in
2079 <make sure you have good level 0 dumps>
2082 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2083 <maybe newfs current's root partition>
2084 <mount current's root partition on directory ${CURRENT_ROOT}>
2085 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
2086 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
2087 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
2088 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
2089 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
2090 <reboot into current>
2091 <do a "native" rebuild/install as described in the previous section>
2092 <maybe install compatibility libraries from ports/misc/compat*>
2096 To upgrade in-place from stable to current
2097 ----------------------------------------------
2098 <make sure you have good level 0 dumps>
2100 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
2101 make installkernel KERNCONF=YOUR_KERNEL_HERE
2103 <reboot in single user> [3]
2110 Make sure that you've read the UPDATING file to understand the
2111 tweaks to various things you need. At this point in the life
2112 cycle of current, things change often and you are on your own
2113 to cope. The defaults can also change, so please read ALL of
2114 the UPDATING entries.
2116 Also, if you are tracking -current, you must be subscribed to
2117 freebsd-current@freebsd.org. Make sure that before you update
2118 your sources that you have read and understood all the recent
2119 messages there. If in doubt, please track -stable which has
2120 much fewer pitfalls.
2122 [1] If you have third party modules, such as vmware, you
2123 should disable them at this point so they don't crash your
2126 [3] From the bootblocks, boot -s, and then do
2131 adjkerntz -i # if CMOS is wall time
2132 Also, when doing a major release upgrade, it is required that
2133 you boot into single user mode to do the installworld.
2135 [4] Note: This step is non-optional. Failure to do this step
2136 can result in a significant reduction in the functionality of the
2137 system. Attempting to do it by hand is not recommended and those
2138 that pursue this avenue should read this file carefully, as well
2139 as the archives of freebsd-current and freebsd-hackers mailing lists
2140 for potential gotchas. The -U option is also useful to consider.
2141 See mergemaster(8) for more information.
2143 [5] Usually this step is a no-op. However, from time to time
2144 you may need to do this if you get unknown user in the following
2145 step. It never hurts to do it all the time. You may need to
2146 install a new mergemaster (cd src/usr.sbin/mergemaster && make
2147 install) after the buildworld before this step if you last updated
2148 from current before 20130425 or from -stable before 20130430.
2150 [6] This only deletes old files and directories. Old libraries
2151 can be deleted by "make delete-old-libs", but you have to make
2152 sure that no program is using those libraries anymore.
2154 [8] The new kernel must be able to run existing binaries used by
2155 an installworld. When upgrading across major versions, the new
2156 kernel's configuration must include the correct COMPAT_FREEBSD<n>
2157 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x
2158 binaries). Failure to do so may leave you with a system that is
2159 hard to boot to recover. A GENERIC kernel will include suitable
2160 compatibility options to run binaries from older branches.
2162 Make sure that you merge any new devices from GENERIC since the
2163 last time you updated your kernel config file.
2165 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2166 "?=" instead of the "=" assignment operator, so that buildworld can
2167 override the CPUTYPE if it needs to.
2169 MAKEOBJDIRPREFIX must be defined in an environment variable, and
2170 not on the command line, or in /etc/make.conf. buildworld will
2171 warn if it is improperly defined.
2174 This file contains a list, in reverse chronological order, of major
2175 breakages in tracking -current. It is not guaranteed to be a complete
2176 list of such breakages, and only contains entries since September 23, 2011.
2177 If you need to see UPDATING entries from before that date, you will need
2178 to fetch an UPDATING file from an older FreeBSD release.
