221 Various LinuxKPI functionality was added which conflicts with DRM.
222 Please update your drm-kmod port to after the __FreeBSD_verison 1300139
226 The stable/13 branch has been created from main.
229 PC Card attachments for all devices have been removed. In the case of
230 wi and cmx, the entire drivers were removed because they were only
231 PC Card devices. FreeBSD_version 1300134 should be used for this
232 since it was bumped so recently.
235 Transport-independent parts of HID support have been split off the USB
236 code in to separate subsystem. Kernel configs which include one of
237 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
238 be updated with adding of "device hid" line.
241 ncurses installation has been modified to only keep the widechar
242 enabled version. Incremental build is broken for that change, so it
243 requires a clean build.
246 The FreeBSD project has migrated from Subversion to Git. Temporary
247 instructions can be found at
248 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
249 and other documents in that repo.
252 The services database has been updated to cover more of the basic
253 services expected in a modern system. The database is big enough
254 that it will cause issues in mergemaster in Releases previous to
255 12.2 and 11.3, or in very old current systems from before r358154.
258 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
259 may be installed from ports or packages.
262 ping6 has been merged into ping. It can now be called as "ping -6".
263 See ping(8) for details.
266 Default value of net.add_addr_allfibs has been changed to 0.
267 If you have multi-fib configuration and rely on existence of all
268 interface routes in every fib, you need to set the above sysctl to 1.
270 The internal pre-processor in the calendar(1) program has been
271 extended to support more C pre-processor commands (e.g. #ifdef, #else,
272 and #undef) and to detect unbalanced conditional statements.
273 Error messages have been extended to include the filename and line
274 number if processing stops to help fixing malformed data files.
277 All the data files for the calendar(1) program, except calendar.freebsd,
278 have been moved to the deskutils/calendar-data port, much like the
279 jewish calendar entries were moved to deskutils/hebcal years ago. After
280 make delete-old-files, you need to install it to retain full
281 functionality. calendar(1) will issue a reminder for files it can't
285 LINT files are no longer generated. We now include the relevant NOTES
286 files. Note: This may cause conflicts with updating in some cases.
287 find sys -name LINT\* -delete
288 is suggested across this commit to remove the generated LINT files.
290 If you have tried to update with generated files there, the svn
291 command you want to un-auger the tree is
294 and then do the above find from the top level. Substitute 'amd64'
295 above with where the error message indicates a conflict.
298 OpenZFS support has been integrated. Do not upgrade root pools until
299 the loader is updated to support zstd. Furthermore, we caution against
300 'zpool upgrade' for the next few weeks. The change should be transparent
301 unless you want to use new features.
303 Not all "NO_CLEAN" build scenarios work across these changes. Many
304 scenarios have been tested and fixed, but rebuilding kernels without
305 rebuilding world may fail.
307 The ZFS cache file has moved from /boot to /etc to match the OpenZFS
308 upstream default. A fallback to /boot has been added for mountroot.
310 Pool auto import behavior at boot has been moved from the kernel module
311 to an explicit "zpool import -a" in one of the rc scripts enabled by
312 zfs_enable=YES. This means your non-root zpools won't auto import until
313 you upgrade your /etc/rc.d files.
316 The resume code now notifies devd with the 'kernel' system
317 rather than the old 'kern' subsystem to be consistent with
318 other use. The old notification will be created as well, but
319 will be removed prior to FreeBSD 14.0.
322 r362275 changed the internal API between the kernel RPC and the
323 NFS modules. As such, all the modules must be recompiled from
327 r364330 modified the internal API used between the NFS modules.
328 As such, all the NFS modules must be re-compiled from sources.
331 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
332 been upgraded to 11.0.0. Please see the 20141231 entry below for
333 information about prerequisites and upgrading, if you are not already
334 using clang 3.5.0 or higher.
337 r364092 modified the internal ABI used between the kernel NFS
338 modules. As such, all of these modules need to be rebuilt
339 from sources, so a version bump was done.
342 Makefile.inc has been updated to work around the issue documented in
343 20200729. It was a case where the optimization of using symbolic links
344 to point to binaries created a situation where we'd run new binaries
345 with old libraries starting midway through the installworld process.
348 r363679 has redefined some undefined behavior in regcomp(3); notably,
349 extraneous escapes of most ordinary characters will no longer be
350 accepted. An exp-run has identified all of the problems with this in
351 ports, but other non-ports software may need extra escapes removed to
352 continue to function.
354 Because of this change, installworld may encounter the following error
355 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
356 you do not halt installworld. Instead, let it run to completion (whether
357 successful or not) and run installworld once more.
360 A new implementation of bc and dc has been imported in r362681. This
361 implementation corrects non-conformant behavior of the previous bc
362 and adds GNU bc compatible options. It offers a number of extensions,
363 is much faster on large values, and has support for message catalogs
364 (a number of languages are already supported, contributions of further
365 languages welcome). The option WITHOUT_GH_BC can be used to build the
366 world with the previous versions of bc and dc.
369 r362639 changed the internal API used between the NFS kernel modules.
370 As such, they all need to be rebuilt from sources.
373 r362158 changed the arguments for VFS_CHECKEXP(). As such, any
374 out of tree file systems need to be modified and rebuilt.
375 Also, any file systems that are modules must be rebuilt.
378 read(2) of a directory fd is now rejected by default. root may
379 re-enable it for system root only on non-ZFS filesystems with the
380 security.bsd.allow_read_dir sysctl(8) MIB if
381 security.bsd.suser_enabled=1.
383 It may be advised to setup aliases for grep to default to `-d skip` if
384 commonly non-recursively grepping a list that includes directories and
385 the potential for the resulting stderr output is not tolerable. Example
386 aliases are now installed, commented out, in /root/.cshrc and
390 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
391 been upgraded to 10.0.1. Please see the 20141231 entry below for
392 information about prerequisites and upgrading, if you are not already
393 using clang 3.5.0 or higher.
396 Support for obsolete compilers has been removed from the build system.
397 Clang 6 and GCC 6.4 are the minimum supported versions.
400 closefrom(2) has been moved under COMPAT12, and replaced in libc with a
401 stub that calls close_range(2). If using a custom kernel configuration,
402 you may want to ensure that the COMPAT_FREEBSD12 option is included, as
403 a slightly older -CURRENT userland and older FreeBSD userlands may not
404 be functional without closefrom(2).
407 Upstream DTS from Linux 5.6 was merged and they now have the SID
408 and THS (Secure ID controller and THermal Sensor) node present.
409 The DTB overlays have now been removed from the tree for the H3/H5 and
410 A64 SoCs and the aw_sid and aw_thermal driver have been updated to
411 deal with upstream DTS. If you are using those overlays you need to
412 remove them from loader.conf and update the DTBs on the FAT partition.
415 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
416 been upgraded to 10.0.0. Please see the 20141231 entry below for
417 information about prerequisites and upgrading, if you are not already
418 using clang 3.5.0 or higher.
421 The amd(8) automount daemon has been removed from the source tree.
422 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
423 amd is still available in the sysutils/am-utils port.
426 Removed brooktree driver (bktr.4) from the tree.
429 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
430 compiler in usr.bin/dtc is used on all architectures which use dtc, and
431 the GPL dtc is available (if needed) from the sysutils/dtc port.
434 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
435 is used by all supported CPU architectures.
438 GCC 4.2.1 has been removed from the tree. The WITH_GCC,
439 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
440 Users who wish to build FreeBSD with GCC must use the external toolchain
444 ncurses has been updated to a newer version (6.2-20200215). Given the ABI
445 has changed, users will have to rebuild all the ports that are linked to
449 The size of struct vnet and the magic cookie have changed.
450 Users need to recompile libkvm and all modules using VIMAGE
451 together with their new kernel.
454 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
455 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
456 your Makefiles and scripts to define MK_<var>=no instead as required.
458 One exception to this is that program or library Makefiles should
459 define MAN to empty rather than setting MK_MAN=no.
462 Clang/LLVM is now the default compiler and LLD the default
466 make universe no longer uses GCC 4.2.1 on any architectures.
467 Architectures not supported by in-tree Clang/LLVM require an
468 external toolchain package.
471 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
472 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
473 options default to off for all supported CPU architectures. As a
474 short-term transition aid they may be enabled via WITH_* options.
475 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
478 Support for armv5 has been disconnected and is being removed. The
479 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
480 You must now use a MACHINE_ARCH of armv6 or armv7. The default
481 MACHINE_ARCH for MACHINE=arm is now armv7.
484 Clang/LLVM is now the default compiler for all powerpc architectures.
485 LLD is now the default linker for powerpc64. The change for powerpc64
486 also includes a change to the ELFv2 ABI, incompatible with the existing
490 Kernel-loadable random(4) modules are no longer unloadable.
493 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
494 been upgraded to 9.0.1. Please see the 20141231 entry below for
495 information about prerequisites and upgrading, if you are not already
496 using clang 3.5.0 or higher.
499 r355677 has modified the internal interface used between the
500 NFS modules in the kernel. As such, they must all be upgraded
501 simultaneously. I will do a version bump for this.
504 The root certificates of the Mozilla CA Certificate Store have been
505 imported into the base system and can be managed with the certctl(8)
506 utility. If you have installed the security/ca_root_nss port or package
507 with the ETCSYMLINK option (the default), be advised that there may be
508 differences between those included in the port and those included in
509 base due to differences in nss branch used as well as general update
510 frequency. Note also that certctl(8) cannot manage certs in the
511 format used by the security/ca_root_nss port.
514 The amd(8) automount daemon has been disabled by default, and will be
515 removed in the future. As of FreeBSD 10.1 the autofs(5) is available
519 The nctgpio and wbwd drivers have been moved to the superio bus.
520 If you have one of these drivers in a kernel configuration, then
521 you should add device superio to it. If you use one of these drivers
522 as a module and you compile a custom set of modules, then you should
523 add superio to the set.
526 KPIs for network drivers to access interface addresses have changed.
527 Users need to recompile NIC driver modules together with kernel.
530 The net.link.tap.user_open sysctl no longer prevents user opening of
531 already created /dev/tapNN devices. Access is still controlled by
532 node permissions, just like tun devices. The net.link.tap.user_open
533 sysctl is now used only to allow users to perform devfs cloning of
534 tap devices, and the subsequent open may not succeed if the user is not
535 in the appropriate group. This sysctl may be deprecated/removed
536 completely in the future.
539 mips, powerpc, and sparc64 are no longer built as part of
540 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
541 not defined, mips, powerpc, and sparc64 builds will look for
542 the xtoolchain binaries and if installed use them for universe
543 builds. As llvm 9.0 becomes vetted for these architectures, they
544 will be removed from the list.
547 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
548 been upgraded to 9.0.0. Please see the 20141231 entry below for
549 information about prerequisites and upgrading, if you are not already
550 using clang 3.5.0 or higher.
553 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
554 GENERIC. They are available as modules and can be loaded by adding
555 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
556 hptnr_load="YES", or hptrr_load="YES", respectively.
559 ntpd no longer by default locks its pages in memory, allowing them
560 to be paged out by the kernel. Use rlimit memlock to restore
561 historic BSD behaviour. For example, add "rlimit memlock 32"
562 to ntp.conf to lock up to 32 MB of ntpd address space in memory.
565 Several of ping6's options have been renamed for better consistency
566 with ping. If you use any of -ARWXaghmrtwx, you must update your
567 scripts. See ping6(8) for details.
570 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
571 and the "-o sync_unmount" and "-o init_backgrounded" mount options have
572 been removed from mount_fusefs(8). You can safely remove them from
573 your scripts, because they had no effect.
575 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
576 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
577 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
578 sysctls have been removed. If you felt the need to set any of them to
579 a non-default value, please tell asomers@FreeBSD.org why.
582 Default permissions on the /var/account/acct file (and copies of it
583 rotated by periodic daily scripts) are changed from 0644 to 0640
584 because the file contains sensitive information that should not be
585 world-readable. If the /var/account directory must be created by
586 rc.d/accounting, the mode used is now 0750. Admins who use the
587 accounting feature are encouraged to change the mode of an existing
588 /var/account directory to 0750 or 0700.
591 Entropy collection and the /dev/random device are no longer optional
592 components. The "device random" option has been removed.
593 Implementations of distilling algorithms can still be made loadable
594 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
597 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
598 been upgraded to 8.0.1. Please see the 20141231 entry below for
599 information about prerequisites and upgrading, if you are not already
600 using clang 3.5.0 or higher.
603 A fix was applied to i386 kernel modules to avoid panics with
604 dpcpu or vnet. Users need to recompile i386 kernel modules
605 having pcpu or vnet sections or they will refuse to load.
608 User-wired pages now have their own counter,
609 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
610 to vm.max_user_wired and changed from an unsigned int to an unsigned
611 long. bhyve VMs wired with the -S are now subject to the user
612 wiring limit; the vm.max_user_wired sysctl may need to be tuned to
613 avoid running into the limit.
616 The IPSEC option has been removed from GENERIC. Users requiring
617 ipsec(4) must now load the ipsec(4) kernel module.
620 The tap(4) driver has been folded into tun(4), and the module has been
621 renamed to tuntap. You should update any kld_list="if_tap" or
622 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
623 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
624 module instead, and "device tap" or "device tun" entries in kernel
625 config files to select the tuntap device instead.
628 The following knobs have been added related to tradeoffs between
629 safe use of the random device and availability in the absence of
632 kern.random.initial_seeding.bypass_before_seeding: tunable; set
633 non-zero to bypass the random device prior to seeding, or zero to
634 block random requests until the random device is initially seeded.
635 For now, set to 1 (unsafe) by default to restore pre-r346250 boot
636 availability properties.
638 kern.random.initial_seeding.read_random_bypassed_before_seeding:
639 read-only diagnostic sysctl that is set when bypass is enabled and
640 read_random(9) is bypassed, to enable programmatic handling of this
641 initial condition, if desired.
643 kern.random.initial_seeding.arc4random_bypassed_before_seeding:
644 Similar to the above, but for for arc4random(9) initial seeding.
646 kern.random.initial_seeding.disable_bypass_warnings: tunable; set
647 non-zero to disable warnings in dmesg when the same conditions are
648 met as for the diagnostic sysctls above. Defaults to zero, i.e.,
649 produce warnings in dmesg when the conditions are met.
652 The loadable random module KPI has changed; the random_infra_init()
653 routine now requires a 3rd function pointer for a bool (*)(void)
654 method that returns true if the random device is seeded (and
655 therefore unblocked).
658 r345895 reverts r320698. This implies that an nfsuserd(8) daemon
659 built from head sources between r320757 (July 6, 2017) and
660 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
661 is added to the command line.
662 nfsuserd daemons built from head sources that are post-r338192 are
663 not affected and should continue to work.
666 The fuse(4) module has been renamed to fusefs(4) for consistency with
667 other filesystems. You should update any kld_load="fuse" entries in
668 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
669 "options FUSE" entries in kernel config files.
672 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
673 8.0.0. Please see the 20141231 entry below for information about
674 prerequisites and upgrading, if you are not already using clang 3.5.0
678 geom_uzip(4) depends on the new module xz. If geom_uzip is statically
679 compiled into your custom kernel, add 'device xz' statement to the
683 drm and drm2 have been removed from the tree. Please see
684 https://wiki.freebsd.org/Graphics for the latest information on
685 migrating to the drm ports.
688 Iflib is no longer unconditionally compiled into the kernel. Drivers
689 using iflib and statically compiled into the kernel, now require
690 the 'device iflib' config option. For the same drivers loaded as
691 modules on kernels not having 'device iflib', the iflib.ko module
692 is loaded automatically.
695 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
696 options no longer exist since r343219 and r343427 respectively;
697 nothing uses them, so they should be just removed from custom
701 r342635 changes the way efibootmgr(8) works by requiring users to add
702 the -b (bootnum) parameter for commands where the bootnum was previously
703 specified with each option. For example 'efibootmgr -B 0001' is now
704 'efibootmgr -B -b 0001'.
707 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
708 in the same as it is applied to NFSv2 and 3. This implies that NFSv4
709 servers that have vfs.nfsd.nfs_privport set will only allow mounts
710 from clients using a reserved port#. Since both the FreeBSD and Linux
711 NFSv4 clients use reserved port#s by default, this should not affect
715 The XLP config has been removed. We can't support 64-bit atomics in this
716 kernel because it is running in 32-bit mode. XLP users must transition
717 to running a 64-bit kernel (XLP64 or XLPN32).
719 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
720 the preferred emulator today and we don't need two different ones.
722 The old sibyte / swarm / Broadcom BCM1250 support has been
723 removed from the mips port.
726 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
727 7.0.1. Please see the 20141231 entry below for information about
728 prerequisites and upgrading, if you are not already using clang 3.5.0
732 Remove the timed and netdate programs from the base tree. Setting
733 the time with these daemons has been obsolete for over a decade.
736 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
737 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
738 it produces broken binaries when ifuncs are in use. Users needing
739 GNU ld should install the binutils port or package.
742 The BSD crtbegin and crtend code has been enabled by default. It has
743 had extensive testing on amd64, arm64, and i386. It can be disabled
744 by building a world with -DWITHOUT_BSD_CRTBEGIN.
747 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
748 has been converted to a port (misc/ctm) and will be removed from
749 FreeBSD-13. It is available as a package (ctm) for all supported
753 The default newsyslog.conf(5) file has been changed to only include
754 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
755 the filenames end in '.conf' and do not begin with a '.'.
757 You should check the configuration files in these two directories match
758 this naming convention. You can verify which configuration files are
759 being included using the command:
763 Ports for the DRM modules have been simplified. Now, amd64 users should
764 just install the drm-kmod port. All others should install
767 Graphics hardware that's newer than about 2010 usually works with
768 drm-kmod. For hardware older than 2013, however, some users will need
769 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
770 than 2008 usually only works in drm-legacy-kmod. The graphics team can
771 only commit to hardware made since 2013 due to the complexity of the
772 market and difficulty to test all the older cards effectively. If you
773 have hardware supported by drm-kmod, you are strongly encouraged to use
774 that as you will get better support.
776 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
777 elsewhere, the drm and drm2 modules will be eliminated from the src base
778 soon (with a limited exception for arm). Please update to the package
779 asap and report any issues to x11@freebsd.org.
781 Generally, anybody using the drm*-kmod packages should add
782 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
783 cross-threading surprises, especially with automatic driver
784 loading from X11 startup. These will become the defaults in 13-current
788 The ixlv(4) driver has been renamed to iavf(4). As a consequence,
789 custom kernel and module loading configuration files must be updated
790 accordingly. Moreover, interfaces previous presented as ixlvN to the
791 system are now exposed as iavfN and network configuration files must
792 be adjusted as necessary.
795 OpenSSL has been updated to version 1.1.1. This update included
796 additional various API changes throughout the base system. It is
797 important to rebuild third-party software after upgrading. The value
798 of __FreeBSD_version has been bumped accordingly.
801 The legacy DRM modules and drivers have now been added to the loader's
802 module blacklist, in favor of loading them with kld_list in rc.conf(5).
803 The module blacklist may be overridden with the loader.conf(5)
804 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
808 The cam(4) based nda(4) driver will be used over nvd(4) by default on
809 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
810 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
811 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
815 Reproducible build mode is now on by default, in preparation for
816 FreeBSD 12.0. This eliminates build metadata such as the user,
817 host, and time from the kernel (and uname), unless the working tree
818 corresponds to a modified checkout from a version control system.
819 The previous behavior can be obtained by setting the /etc/src.conf
820 knob WITHOUT_REPRODUCIBLE_BUILD.
823 The Yarrow CSPRNG has been removed from the kernel as it has not been
824 supported by its designers since at least 2003. Fortuna has been the
825 default since FreeBSD-11.
828 devctl freeze/thaw have gone into the tree, the rc scripts have been
829 updated to use them and devmatch has been changed. You should update
830 kernel, userland and rc scripts all at the same time.
833 The default interpreter has been switched from 4th to Lua.
834 LOADER_DEFAULT_INTERP, documented in build(7), will override the default
835 interpreter. If you have custom FORTH code you will need to set
836 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
837 src.conf for the build. This will create default hard links between
838 loader and loader_4th instead of loader and loader_lua, the new default.
839 If you are using UEFI it will create the proper hard link to loader.efi.
841 bhyve uses userboot.so. It remains 4th-only until some issues are solved
842 regarding coexisting with multiple versions of FreeBSD are resolved.
845 ls(1) now respects the COLORTERM environment variable used in other
846 systems and software to indicate that a colored terminal is both
847 supported and desired. If ls(1) is suddenly emitting colors, they may
848 be disabled again by either removing the unwanted COLORTERM from your
849 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
850 may not be observed in a future release.
853 The default pager for most commands has been changed to "less". To
854 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
858 The jedec_ts(4) driver has been removed. A superset of its functionality
859 is available in the jedec_dimm(4) driver, and the manpage for that
860 driver includes migration instructions. If you have "device jedec_ts"
861 in your kernel configuration file, it must be removed.
864 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
865 This should have no effect if the kernel is booted via BIOS/legacy boot.
866 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
867 has a buggy firmware that prevents a successful boot due to use of
871 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
872 support has been removed from the tree. These ports were
873 obsolete and/or known to be broken for many years.
876 loader.efi has been augmented to participate more fully in the
877 UEFI boot manager protocol. loader.efi will now look at the
878 BootXXXX environment variable to determine if a specific kernel
879 or root partition was specified. XXXX is derived from BootCurrent.
880 efibootmgr(8) manages these standard UEFI variables.
883 zfsloader's functionality has now been folded into loader.
884 zfsloader is no longer necessary once you've updated your
885 boot blocks. For a transition period, we will install a
886 hardlink for zfsloader to loader to allow a smooth transition
887 until the boot blocks can be updated (hard link because old
888 zfs boot blocks don't understand symlinks).
891 ARM64 now have efifb support, if you want to have serial console
892 on your arm64 board when an screen is connected and the bootloader
893 setup a frame buffer for us to use, just add :
897 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
898 an screen connected as the firmware will setup a frame buffer are that
899 u-boot will expose as an EFI frame buffer.
902 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
903 or take steps to update /etc/passwd before doing installworld on
904 existing systems. Do not skip the "mergemaster -Fp" step before
905 installworld, as described in the update procedures near the bottom
906 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
907 if the new mac_ntpd(4) policy is available, unless ntpd_flags or
908 the ntp config file contain options that change file/dir locations.
909 When such options (e.g., "statsdir" or "crypto") are used, ntpd can
910 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
911 taking steps to ensure that all required files/dirs are accessible
915 Big endian arm support has been removed.
918 The static environment setup in kernel configs is no longer mutually
919 exclusive with the loader(8) environment by default. In order to
920 restore the previous default behavior of disabling the loader(8)
921 environment if a static environment is present, you must specify
922 loader_env.disabled=1 in the static environment.
925 The ABI of syscalls used by management tools like sockstat and
926 netstat has been broken to allow 32-bit binaries to work on
927 64-bit kernels without modification. These programs will need
928 to match the kernel in order to function. External programs may
929 require minor modifications to accommodate a change of type in
930 structures from pointers to 64-bit virtual addresses.
933 On i386 and amd64 atomics are now inlined. Out of tree modules using
934 atomics will need to be rebuilt.
937 The '%I' format in the kern.corefile sysctl limits the number of
938 core files that a process can generate to the number stored in the
939 debug.ncores sysctl. The '%I' format is replaced by the single digit
940 index. Previously, if all indexes were taken the kernel would overwrite
941 only a core file with the highest index in a filename.
942 Currently the system will create a new core file if there is a free
943 index or if all slots are taken it will overwrite the oldest one.
946 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
947 6.0.1. Please see the 20141231 entry below for information about
948 prerequisites and upgrading, if you are not already using clang 3.5.0
952 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
953 needed to be changed to work with it. This change was made with r335763
954 and requires a mergemaster / etcupdate / etc to update the installed
958 r334930 changed the interface between the NFS modules, so they all
959 need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
962 As of r334391 lld is the default amd64 system linker; it is installed
963 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
967 The kernel / userland interface for devinfo changed, so you'll
968 need a new kernel and userland as a pair for it to work (rebuilding
969 lib/libdevinfo is all that's required). devinfo and devmatch will
970 not work, but everything else will when there's a mismatch.
973 The on-disk format for hwpmc callchain records has changed to include
974 threadid corresponding to a given record. This changes the field offsets
975 and thus requires that libpmcstat be rebuilt before using a kernel
979 The vxge(4) driver has been removed. This driver was introduced into
980 HEAD one week before the Exar left the Ethernet market and is not
981 known to be used. If you have device vxge in your kernel config file
985 The amd64 kernel now requires a ld that supports ifunc to produce a
986 working kernel, either lld or a newer binutils. lld is built by default
987 on amd64, and the 'buildkernel' target uses it automatically. However,
988 it is not the default linker, so building the kernel the traditional
989 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
990 binutils port/package). lld will soon be default, and this requirement
993 NOTE: As of r334391 lld is the default system linker on amd64, and no
994 workaround is necessary.
997 The nxge(4) driver has been removed. This driver was for PCI-X 10g
998 cards made by s2io/Neterion. The company was acquired by Exar and
999 no longer sells or supports Ethernet products. If you have device
1000 nxge in your kernel config file it must be removed.
1003 The tz database (tzdb) has been updated to 2018e. This version more
1004 correctly models time stamps in time zones with negative DST such as
1005 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
1006 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
1007 time zone abbreviations and the tm_isdst flag.
1010 The ixgb(4) driver has been removed. This driver was for an early and
1011 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
1012 quickly shifted to the long lived ixgbe family. If you have device
1013 ixgb in your kernel config file it must be removed.
1016 The lmc(4) driver has been removed. This was a WAN interface
1017 card that was already reportedly rare in 2003, and had an ambiguous
1018 license. If you have device lmc in your kernel config file it must
1022 Support for Arcnet networks has been removed. If you have device
1023 arcnet or device cm in your kernel config file they must be
1027 Support for FDDI networks has been removed. If you have device
1028 fddi or device fpa in your kernel config file they must be
1032 In addition to supporting RFC 3164 formatted messages, the
1033 syslogd(8) service is now capable of parsing RFC 5424 formatted
1034 log messages. The main benefit of using RFC 5424 is that clients
1035 may now send log messages with timestamps containing year numbers,
1036 microseconds and time zone offsets.
1038 Similarly, the syslog(3) C library function has been altered to
1039 send RFC 5424 formatted messages to the local system logging
1040 daemon. On systems using syslogd(8), this change should have no
1041 negative impact, as long as syslogd(8) and the C library are
1042 updated at the same time. On systems using a different system
1043 logging daemon, it may be necessary to make configuration
1044 adjustments, depending on the software used.
1046 When using syslog-ng, add the 'syslog-protocol' flag to local
1047 input sources to enable parsing of RFC 5424 formatted messages:
1050 unix-dgram("/var/run/log" flags(syslog-protocol));
1053 When using rsyslog, disable the 'SysSock.UseSpecialParser' option
1054 of the 'imuxsock' module to let messages be processed by the
1055 regular RFC 3164/5424 parsing pipeline:
1057 module(load="imuxsock" SysSock.UseSpecialParser="off")
1059 Do note that these changes only affect communication between local
1060 applications and syslogd(8). The format that syslogd(8) uses to
1061 store messages on disk or forward messages to other systems
1062 remains unchanged. syslogd(8) still uses RFC 3164 for these
1063 purposes. Options to customize this behaviour will be added in the
1064 future. Utilities that process log files stored in /var/log are
1065 thus expected to continue to function as before.
1067 __FreeBSD_version has been incremented to 1200061 to denote this
1071 Support for token ring networks has been removed. If you
1072 have "device token" in your kernel config you should remove
1073 it. No device drivers supported token ring.
1076 makefs was modified to be able to tag ISO9660 El Torito boot catalog
1077 entries as EFI instead of overloading the i386 tag as done previously.
1078 The amd64 mkisoimages.sh script used to build amd64 ISO images for
1079 release was updated to use this. This may mean that makefs must be
1080 updated before "make cdrom" can be run in the release directory. This
1081 should be as simple as:
1083 $ cd $SRCDIR/usr.sbin/makefs
1084 $ make depend all install
1087 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
1088 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
1089 Co-existence for the transition period will come shortly. Booting is a
1090 complex environment and test coverage for Lua-enabled loaders has been
1091 thin, so it would be prudent to assume it might not work and make
1092 provisions for backup boot methods.
1095 devmatch functionality has been turned on in devd. It will automatically
1096 load drivers for unattached devices. This may cause unexpected drivers
1097 to be loaded. Please report any problems to current@ and
1101 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
1102 6.0.0. Please see the 20141231 entry below for information about
1103 prerequisites and upgrading, if you are not already using clang 3.5.0
1107 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
1108 This means it is used to link the kernel and userland libraries and
1109 executables, but is not yet installed as /usr/bin/ld by default.
1111 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
1112 WITHOUT_LLD_BOOTSTRAP=yes
1115 On i386, pmtimer has been removed. Its functionality has been folded
1116 into apm. It was a no-op on ACPI in current for a while now (but was
1117 still needed on i386 in FreeBSD 11 and earlier). Users may need to
1118 remove it from kernel config files.
1121 The use of RSS hash from the network card aka flowid has been
1122 disabled by default for lagg(4) as it's currently incompatible with
1123 the lacp and loadbalance protocols.
1125 This can be re-enabled by setting the following in loader.conf:
1126 net.link.lagg.default_use_flowid="1"
1129 The SW_WATCHDOG option is no longer necessary to enable the
1130 hardclock-based software watchdog if no hardware watchdog is
1131 configured. As before, SW_WATCHDOG will cause the software
1132 watchdog to be enabled even if a hardware watchdog is configured.
1135 r326887 fixes the issue described in the 20171214 UPDATING entry.
1136 r326888 flips the switch back to building GELI support always.
1139 r362593 broke ZFS + GELI support for reasons unknown. However,
1140 it also broke ZFS support generally, so GELI has been turned off
1141 by default as the lesser evil in r326857. If you boot off ZFS and/or
1142 GELI, it might not be a good time to update.
1145 PowerPC users must update loader(8) by rebuilding world before
1146 installing a new kernel, as the protocol connecting them has
1147 changed. Without the update, loader metadata will not be passed
1148 successfully to the kernel and users will have to enter their
1149 root partition at the kernel mountroot prompt to continue booting.
1150 Newer versions of loader can boot old kernels without issue.
1153 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
1154 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
1155 to WITH/OUT_LOADER_GELI.
1158 The naive and non-compliant support of posix_fallocate(2) in ZFS
1159 has been removed as of r325320. The system call now returns EINVAL
1160 when used on a ZFS file. Although the new behavior complies with the
1161 standard, some consumers are not prepared to cope with it.
1162 One known victim is lld prior to r325420.
1165 Building in a FreeBSD src checkout will automatically create object
1166 directories now rather than store files in the current directory if
1167 'make obj' was not ran. Calling 'make obj' is no longer necessary.
1168 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
1169 /etc/src-env.conf (not /etc/src.conf), or passing the option in the
1173 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
1174 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
1175 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
1176 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
1177 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
1178 The UNIFIED_OBJDIR option is a transitional feature that will be
1179 removed for 12.0 release; please migrate to the new format for any
1180 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
1181 than hardcoding paths.
1184 The native-xtools target no longer installs the files by default to the
1185 OBJDIR. Use the native-xtools-install target with a DESTDIR to install
1186 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
1189 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
1190 options are changing from controlling the build if defined / undefined
1191 to controlling the build with explicit 'yes' or 'no' values. They will
1192 shift to WITH/WITHOUT options to match other options in the system.
1195 libstand has turned into a private library for sys/boot use only.
1196 It is no longer supported as a public interface outside of sys/boot.
1199 The arm port has split armv6 into armv6 and armv7. armv7 is now
1200 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
1201 and are running a kernel from before r324363, you will need to add
1202 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
1205 When building multiple kernels using KERNCONF, non-existent KERNCONF
1206 files will produce an error and buildkernel will fail. Previously
1207 missing KERNCONF files silently failed giving no indication as to
1208 why, only to subsequently discover during installkernel that the
1209 desired kernel was never built in the first place.
1212 The default serial number format for CTL LUNs has changed. This will
1213 affect users who use /dev/diskid/* device nodes, or whose FibreChannel
1214 or iSCSI clients care about their LUNs' serial numbers. Users who
1215 require serial number stability should hardcode serial numbers in
1219 For 32-bit arm compiled for hard-float support, soft-floating point
1220 binaries now always get their shared libraries from
1221 LD_SOFT_LIBRARY_PATH (in the past, this was only used if
1222 /usr/libsoft also existed). Only users with a hard-float ld.so, but
1223 soft-float everything else should be affected.
1226 The geli password typed at boot is now hidden. To restore the previous
1227 behavior, see geli(8) for configuration options.
1230 Move PMTUD blackhole counters to TCPSTATS and remove them from bare
1231 sysctl values. Minor nit, but requires a rebuild of both world/kernel
1235 "make check" behavior (made in ^/head@r295380) has been changed to
1236 execute from a limited sandbox, as opposed to executing from
1240 - The "beforecheck" and "aftercheck" targets are now specified.
1241 - ${CHECKDIR} (added in commit noted above) has been removed.
1242 - Legacy behavior can be enabled by setting
1243 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
1245 If the limited sandbox mode is enabled, "make check" will execute
1246 "make distribution", then install, execute the tests, and clean up the
1247 sandbox if successful.
1249 The "make distribution" and "make install" targets are typically run as
1250 root to set appropriate permissions and ownership at installation time.
1251 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
1252 environment if executing "make check" with limited sandbox mode using
1253 an unprivileged user.
1256 Since the switch to GPT disk labels, fsck for UFS/FFS has been
1257 unable to automatically find alternate superblocks. As of r322297,
1258 the information needed to find alternate superblocks has been
1259 moved to the end of the area reserved for the boot block.
1260 Filesystems created with a newfs of this vintage or later
1261 will create the recovery information. If you have a filesystem
1262 created prior to this change and wish to have a recovery block
1263 created for your filesystem, you can do so by running fsck in
1264 foreground mode (i.e., do not use the -p or -y options). As it
1265 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
1266 to which you should answer yes.
1269 As of r321665, an NFSv4 server configuration that services
1270 Kerberos mounts or clients that do not support the uid/gid in
1271 owner/owner_group string capability, must explicitly enable
1272 the nfsuserd daemon by adding nfsuserd_enable="YES" to the
1273 machine's /etc/rc.conf file.
1276 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
1277 Please see the 20141231 entry below for information about prerequisites
1278 and upgrading, if you are not already using clang 3.5.0 or higher.
1281 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
1282 r-commands (rlogin, rsh, etc.) to be built with the base system.
1285 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
1286 a very major ABI incompatible change, so users of FreeBSD/powerpc must
1287 be careful when performing source upgrades. It is best to run
1288 'make installworld' from an alternate root system, either a live
1289 CD/memory stick, or a temporary root partition. Additionally, all ports
1290 must be recompiled. powerpc64 is largely unaffected, except in the case
1291 of 32-bit compatibility. All 32-bit binaries will be affected.
1294 Forward compatibility for the "ino64" project have been committed. This
1295 will allow most new binaries to run on older kernels in a limited
1296 fashion. This prevents many of the common foot-shooting actions in the
1297 upgrade as well as the limited ability to roll back the kernel across
1298 the ino64 upgrade. Complicated use cases may not work properly, though
1299 enough simpler ones work to allow recovery in most situations.
1302 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
1303 if you require the GPL compiler.
1306 The internal ABI used for communication between the NFS kernel modules
1307 was changed by r320085, so __FreeBSD_version was bumped to
1308 ensure all the NFS related modules are updated together.
1311 The ABI of struct event was changed by extending the data
1312 member to 64bit and adding ext fields. For upgrade, same
1313 precautions as for the entry 20170523 "ino64" must be
1317 The GNU roff toolchain has been removed from base. To render manpages
1318 which are not supported by mandoc(1), man(1) can fallback on GNU roff
1319 from ports (and recommends to install it).
1320 To render roff(7) documents, consider using GNU roff from ports or the
1321 heirloom doctools roff toolchain from ports via pkg install groff or
1322 via pkg install heirloom-doctools.
1325 The ath(4) and ath_hal(4) modules now build piecemeal to allow for
1326 smaller runtime footprint builds. This is useful for embedded systems
1327 which only require one chipset support.
1329 If you load it as a module, make sure this is in /boot/loader.conf:
1333 This will load the HAL, all chip/RF backends and if_ath_pci.
1334 If you have if_ath_pci in /boot/loader.conf, ensure it is after
1335 if_ath or it will not load any HAL chipset support.
1337 If you want to selectively load things (eg on ye cheape ARM/MIPS
1338 platforms where RAM is at a premium) you should:
1341 * load the chip modules in question
1342 * load ath_rate, ath_dfs
1344 * load if_ath_pci and/or if_ath_ahb depending upon your particular
1345 bus bind type - this is where probe/attach is done.
1347 For further comments/feedback, poke adrian@ .
1350 The "ino64" 64-bit inode project has been committed, which extends
1351 a number of types to 64 bits. Upgrading in place requires care and
1352 adherence to the documented upgrade procedure.
1354 If using a custom kernel configuration ensure that the
1355 COMPAT_FREEBSD11 option is included (as during the upgrade the
1356 system will be running the ino64 kernel with the existing world).
1358 For the safest in-place upgrade begin by removing previous build
1359 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full
1360 procedure documented below under the heading "To rebuild everything and
1361 install it on the current system." Specifically, a reboot is required
1362 after installing the new kernel before installing world. While an
1363 installworld normally works by accident from multiuser after rebooting
1364 the proper kernel, there are many cases where this will fail across this
1365 upgrade and installworld from single user is required.
1368 The NATM framework including the en(4), fatm(4), hatm(4), and
1369 patm(4) devices has been removed. Consumers should plan a
1370 migration before the end-of-life date for FreeBSD 11.
1373 GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1374 diff has not been implemented, if those are needed a newer version of
1375 GNU diff is available via the diffutils package under the gdiff name.
1378 As of r316810 for ipfilter, keep frags is no longer assumed when
1379 keep state is specified in a rule. r316810 aligns ipfilter with
1380 documentation in man pages separating keep frags from keep state.
1381 This allows keep state to be specified without forcing keep frags
1382 and allows keep frags to be specified independently of keep state.
1383 To maintain previous behaviour, also specify keep frags with
1384 keep state (as documented in ipf.conf.5).
1387 arm64 builds now use the base system LLD 4.0.0 linker by default,
1388 instead of requiring that the aarch64-binutils port or package be
1389 installed. To continue using aarch64-binutils, set
1390 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
1393 The UDP optimization in entry 20160818 that added the sysctl
1394 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
1395 packets will no longer be treated as L3 broadcast packets.
1398 Binds and sends to the loopback addresses, IPv6 and IPv4, will now
1399 use any explicitly assigned loopback address available in the jail
1400 instead of using the first assigned address of the jail.
1403 The ctl.ko module no longer implements the iSCSI target frontend:
1404 cfiscsi.ko does instead.
1406 If building cfiscsi.ko as a kernel module, the module can be loaded
1407 via one of the following methods:
1408 - `cfiscsi_load="YES"` in loader.conf(5).
1409 - Add `cfiscsi` to `$kld_list` in rc.conf(5).
1410 - ctladm(8)/ctld(8), when compiled with iSCSI support
1411 (`WITH_ISCSI=yes` in src.conf(5))
1413 Please see cfiscsi(4) for more details.
1416 The mmcsd.ko module now additionally depends on geom_flashmap.ko.
1417 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
1418 same source (previously, the dependency of mmcsd.ko on mmc.ko was
1419 missing, but mmcsd.ko now will refuse to load if it is incompatible
1423 The syntax of ipfw(8) named states was changed to avoid ambiguity.
1424 If you have used named states in the firewall rules, you need to modify
1425 them after installworld and before rebooting. Now named states must
1426 be prefixed with colon.
1429 The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1430 removed as the userland we provide cannot use them. The KMS version
1431 (sys/dev/drm2) supports the same hardware.
1434 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
1435 Please see the 20141231 entry below for information about prerequisites
1436 and upgrading, if you are not already using clang 3.5.0 or higher.
1439 The code that provides support for ZFS .zfs/ directory functionality
1440 has been reimplemented. It's not possible now to create a snapshot
1441 by mkdir under .zfs/snapshot/. That should be the only user visible
1445 EISA bus support has been removed. The WITH_EISA option is no longer
1449 MCA bus support has been removed.
1452 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1453 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
1456 The EM_MULTIQUEUE kernel configuration option is deprecated now that
1457 the em(4) driver conforms to iflib specifications.
1460 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1461 IFLIB. If you have a custom kernel configuration that excludes em(4)
1462 but you use igb(4), you need to re-add em(4) to your custom
1466 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
1467 Please see the 20141231 entry below for information about prerequisites
1468 and upgrading, if you are not already using clang 3.5.0 or higher.
1471 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
1472 Please see the 20141231 entry below for information about prerequisites
1473 and upgrading, if you are not already using clang 3.5.0 or higher.
1476 The layout of the pmap structure has changed for powerpc to put the pmap
1477 statistics at the front for all CPU variations. libkvm(3) and all tools
1478 that link against it need to be recompiled.
1481 isl(4) and cyapa(4) drivers now require a new driver,
1482 chromebook_platform(4), to work properly on Chromebook-class hardware.
1483 On other types of hardware the drivers may need to be configured using
1484 device hints. Please see the corresponding manual pages for details.
1487 The urtwn(4) driver was merged into rtwn(4) and now consists of
1488 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
1490 Also, firmware for RTL8188CE was renamed due to possible name
1491 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
1494 GNU rcs has been removed from base. It is available as packages:
1495 - rcs: Latest GPLv3 GNU rcs version.
1496 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
1500 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1501 modules now requires that the kernel configuration contain the
1502 TCP_HHOOK option. (This option is included in the GENERIC kernel.)
1505 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
1506 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
1509 Relocatable object files with the extension of .So have been renamed
1510 to use an extension of .pico instead. The purpose of this change is
1511 to avoid a name clash with shared libraries on case-insensitive file
1512 systems. On those file systems, foo.So is the same file as foo.so.
1515 GNU rcs has been turned off by default. It can (temporarily) be built
1516 again by adding WITH_RCS knob in src.conf.
1517 Otherwise, GNU rcs is available from packages:
1518 - rcs: Latest GPLv3 GNU rcs version.
1519 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
1522 The backup_uses_rcs functionality has been removed from rc.subr.
1525 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
1526 two separate components, QUEUE_MACRO_DEBUG_TRACE and
1527 QUEUE_MACRO_DEBUG_TRASH. Define both for the original
1528 QUEUE_MACRO_DEBUG behavior.
1531 r304787 changed some ioctl interfaces between the iSCSI userspace
1532 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
1533 rebuilt to work with new kernels. __FreeBSD_version has been bumped
1537 The UDP receive code has been updated to only treat incoming UDP
1538 packets that were addressed to an L2 broadcast address as L3
1539 broadcast packets. It is not expected that this will affect any
1540 standards-conforming UDP application. The new behaviour can be
1541 disabled by setting the sysctl net.inet.udp.require_l2_bcast to
1545 Remove the openbsd_poll system call.
1546 __FreeBSD_version has been bumped because of this.
1549 The stable/11 branch has been created from head@r302406.
1552 The libc stub for the pipe(2) system call has been replaced with
1553 a wrapper that calls the pipe2(2) system call and the pipe(2)
1554 system call is now only implemented by the kernels that include
1555 "options COMPAT_FREEBSD10" in their config file (this is the
1556 default). Users should ensure that this option is enabled in
1557 their kernel or upgrade userspace to r302092 before upgrading their
1561 CAM will now strip leading spaces from SCSI disks' serial numbers.
1562 This will affect users who create UFS filesystems on SCSI disks using
1563 those disk's diskid device nodes. For example, if /etc/fstab
1564 previously contained a line like
1565 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1566 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
1567 transforms like gmirror may also be affected. ZFS users should
1571 The bitstring(3) API has been updated with new functionality and
1572 improved performance. But it is binary-incompatible with the old API.
1573 Objects built with the new headers may not be linked against objects
1574 built with the old headers.
1577 The brk and sbrk functions have been removed from libc on arm64.
1578 Binutils from ports has been updated to not link to these
1579 functions and should be updated to the latest version before
1580 installing a new libc.
1583 The armv6 port now defaults to hard float ABI. Limited support
1584 for running both hardfloat and soft float on the same system
1585 is available using the libraries installed with -DWITH_LIBSOFT.
1586 This has only been tested as an upgrade path for installworld
1587 and packages may fail or need manual intervention to run. New
1588 packages will be needed.
1590 To update an existing self-hosted armv6hf system, you must add
1591 TARGET_ARCH=armv6 on the make command line for both the build
1592 and the install steps.
1595 Kernel modules compiled outside of a kernel build now default to
1596 installing to /boot/modules instead of /boot/kernel. Many kernel
1597 modules built this way (such as those in ports) already overrode
1598 KMODDIR explicitly to install into /boot/modules. However,
1599 manually building and installing a module from /sys/modules will
1600 now install to /boot/modules instead of /boot/kernel.
1603 The CAM I/O scheduler has been committed to the kernel. There should be
1604 no user visible impact. This does enable NCQ Trim on ada SSDs. While the
1605 list of known rogues that claim support for this but actually corrupt
1606 data is believed to be complete, be on the lookout for data
1607 corruption. The known rogue list is believed to be complete:
1609 o Crucial MX100, M550 drives with MU01 firmware.
1610 o Micron M510 and M550 drives with MU01 firmware.
1611 o Micron M500 prior to MU07 firmware
1612 o Samsung 830, 840, and 850 all firmwares
1613 o FCCT M500 all firmwares
1615 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1616 with working NCQ TRIM. For Micron branded drives, see your sales rep for
1617 updated firmware. Black listed drives will work correctly because these
1618 drives work correctly so long as no NCQ TRIMs are sent to them. Given
1619 this list is the same as found in Linux, it's believed there are no
1620 other rogues in the market place. All other models from the above
1623 To be safe, if you are at all concerned, you can quirk each of your
1624 drives to prevent NCQ from being sent by setting:
1625 kern.cam.ada.X.quirks="0x2"
1626 in loader.conf. If the drive requires the 4k sector quirk, set the
1627 quirks entry to 0x3.
1630 The FAST_DEPEND build option has been removed and its functionality is
1631 now the one true way. The old mkdep(1) style of 'make depend' has
1632 been removed. See 20160311 for further details.
1635 Resource range types have grown from unsigned long to uintmax_t. All
1636 drivers, and anything using libdevinfo, need to be recompiled.
1639 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1640 builds. It no longer runs mkdep(1) during 'make depend', and the
1641 'make depend' stage can safely be skipped now as it is auto ran
1642 when building 'make all' and will generate all SRCS and DPSRCS before
1643 building anything else. Dependencies are gathered at compile time with
1644 -MF flags kept in separate .depend files per object file. Users should
1645 run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1646 stale .depend files.
1649 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1650 kernel modules. Therefore, if you load any kernel modules at boot time,
1651 please install the boot loaders after you install the kernel, but before
1655 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1656 make installkernel KERNCONF=YOUR_KERNEL_HERE
1657 make -C sys/boot install
1658 <reboot in single user>
1660 Then follow the usual steps, described in the General Notes section,
1664 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
1665 see the 20141231 entry below for information about prerequisites and
1666 upgrading, if you are not already using clang 3.5.0 or higher.
1669 The AIO subsystem is now a standard part of the kernel. The
1670 VFS_AIO kernel option and aio.ko kernel module have been removed.
1671 Due to stability concerns, asynchronous I/O requests are only
1672 permitted on sockets and raw disks by default. To enable
1673 asynchronous I/O requests on all file types, set the
1674 vfs.aio.enable_unsafe sysctl to a non-zero value.
1677 The ELF object manipulation tool objcopy is now provided by the
1678 ELF Tool Chain project rather than by GNU binutils. It should be a
1679 drop-in replacement, with the addition of arm64 support. The
1680 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1681 to obtain the GNU version if necessary.
1684 Building ZFS pools on top of zvols is prohibited by default. That
1685 feature has never worked safely; it's always been prone to deadlocks.
1686 Using a zvol as the backing store for a VM guest's virtual disk will
1687 still work, even if the guest is using ZFS. Legacy behavior can be
1688 restored by setting vfs.zfs.vol.recursive=1.
1691 The NONE and HPN patches has been removed from OpenSSH. They are
1692 still available in the security/openssh-portable port.
1695 With the addition of ypldap(8), a new _ypldap user is now required
1696 during installworld. "mergemaster -p" can be used to add the user
1697 prior to installworld, as documented in the handbook.
1700 The tftp loader (pxeboot) now uses the option root-path directive. As a
1701 consequence it no longer looks for a pxeboot.4th file on the tftp
1702 server. Instead it uses the regular /boot infrastructure as with the
1706 The code to start recording plug and play data into the modules has
1707 been committed. While the old tools will properly build a new kernel,
1708 a number of warnings about "unknown metadata record 4" will be produced
1709 for an older kldxref. To avoid such warnings, make sure to rebuild
1710 the kernel toolchain (or world). Make sure that you have r292078 or
1711 later when trying to build 292077 or later before rebuilding.
1714 Debug data files are now built by default with 'make buildworld' and
1715 installed with 'make installworld'. This facilitates debugging but
1716 requires more disk space both during the build and for the installed
1717 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1721 r291527 changed the internal interface between the nfsd.ko and
1722 nfscommon.ko modules. As such, they must both be upgraded to-gether.
1723 __FreeBSD_version has been bumped because of this.
1726 Add support for unicode collation strings leads to a change of
1727 order of files listed by ls(1) for example. To get back to the old
1728 behaviour, set LC_COLLATE environment variable to "C".
1730 Databases administrators will need to reindex their databases given
1731 collation results will be different.
1733 Due to a bug in install(1) it is recommended to remove the ancient
1734 locales before running make installworld.
1736 rm -rf /usr/share/locale/*
1739 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
1740 libcrypto.so.7 or libssl.so.7 must be recompiled.
1743 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1744 Kernel modules isp_2400_multi and isp_2500_multi were removed and
1745 should be replaced with isp_2400 and isp_2500 modules respectively.
1748 The build previously allowed using 'make -n' to not recurse into
1749 sub-directories while showing what commands would be executed, and
1750 'make -n -n' to recursively show commands. Now 'make -n' will recurse
1751 and 'make -N' will not.
1754 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1755 and etcupdate will now use this file. A custom sendmail.cf is now
1756 updated via this mechanism rather than via installworld. If you had
1757 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1758 want to remove the exclusion or change it to "always install".
1759 /etc/mail/sendmail.cf is now managed the same way regardless of
1760 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
1761 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1764 Compatibility shims for legacy ATA device names have been removed.
1765 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
1766 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
1767 environment variables, /dev/ad* and /dev/ar* symbolic links.
1770 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
1771 Please see the 20141231 entry below for information about prerequisites
1772 and upgrading, if you are not already using clang 3.5.0 or higher.
1775 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
1776 and renamed from .symbols to .debug. This reduces the size requirements
1777 on the boot partition or file system and provides consistency with
1778 userland debug files.
1780 When using the supported kernel installation method the
1781 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
1782 as is done with /boot/kernel.
1784 Developers wishing to maintain the historical behavior of installing
1785 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
1788 The wireless drivers had undergone changes that remove the 'parent
1789 interface' from the ifconfig -l output. The rc.d network scripts
1790 used to check presence of a parent interface in the list, so old
1791 scripts would fail to start wireless networking. Thus, etcupdate(3)
1792 or mergemaster(8) run is required after kernel update, to update your
1793 rc.d scripts in /etc.
1796 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
1797 These configurations are now automatically interpreted as
1798 'scrub fragment reassemble'.
1801 Kernel-loadable modules for the random(4) device are back. To use
1802 them, the kernel must have
1805 options RANDOM_LOADABLE
1807 kldload(8) can then be used to load random_fortuna.ko
1808 or random_yarrow.ko. Please note that due to the indirect
1809 function calls that the loadable modules need to provide,
1810 the build-in variants will be slightly more efficient.
1812 The random(4) kernel option RANDOM_DUMMY has been retired due to
1813 unpopularity. It was not all that useful anyway.
1816 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
1817 Control over building the ELF Tool Chain tools is now provided by
1818 the WITHOUT_TOOLCHAIN knob.
1821 The polarity of Pulse Per Second (PPS) capture events with the
1822 uart(4) driver has been corrected. Prior to this change the PPS
1823 "assert" event corresponded to the trailing edge of a positive PPS
1824 pulse and the "clear" event was the leading edge of the next pulse.
1826 As the width of a PPS pulse in a typical GPS receiver is on the
1827 order of 1 millisecond, most users will not notice any significant
1828 difference with this change.
1830 Anyone who has compensated for the historical polarity reversal by
1831 configuring a negative offset equal to the pulse width will need to
1832 remove that workaround.
1835 The default group assigned to /dev/dri entries has been changed
1836 from 'wheel' to 'video' with the id of '44'. If you want to have
1837 access to the dri devices please add yourself to the video group
1840 # pw groupmod video -m $USER
1843 The menu.rc and loader.rc files will now be replaced during
1844 upgrades. Please migrate local changes to menu.rc.local and
1845 loader.rc.local instead.
1848 GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1849 strings and strip have been removed. The src.conf(5) knob
1850 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1853 As ZFS requires more kernel stack pages than is the default on some
1854 architectures e.g. i386, it now warns if KSTACK_PAGES is less than
1855 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
1857 Please consider using 'options KSTACK_PAGES=X' where X is greater
1858 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
1861 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
1862 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1863 default, i.e., they will not contain "::". For example, instead
1864 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
1865 to have a more specific match, such as different map entries for
1866 IPv6:0:0 vs IPv6:0. This change requires that configuration
1867 data (including maps, files, classes, custom ruleset, etc.) must
1868 use the same format, so make certain such configuration data is
1869 upgrading. As a very simple check search for patterns like
1870 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
1871 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1872 the cf option UseCompressedIPv6Addresses.
1875 The default kernel entropy-processing algorithm is now
1876 Fortuna, replacing Yarrow.
1878 Assuming you have 'device random' in your kernel config
1879 file, the configurations allow a kernel option to override
1880 this default. You may choose *ONE* of:
1882 options RANDOM_YARROW # Legacy /dev/random algorithm.
1883 options RANDOM_DUMMY # Blocking-only driver.
1885 If you have neither, you get Fortuna. For most people,
1886 read no further, Fortuna will give a /dev/random that works
1887 like it always used to, and the difference will be irrelevant.
1889 If you remove 'device random', you get *NO* kernel-processed
1890 entropy at all. This may be acceptable to folks building
1891 embedded systems, but has complications. Carry on reading,
1892 and it is assumed you know what you need.
1894 *PLEASE* read random(4) and random(9) if you are in the
1895 habit of tweaking kernel configs, and/or if you are a member
1896 of the embedded community, wanting specific and not-usual
1897 behaviour from your security subsystems.
1899 NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1900 random', you will NOT have a functioning /dev/random, and
1901 many cryptographic features will not work, including SSH.
1902 You may also find strange behaviour from the random(3) set
1903 of library functions, in particular sranddev(3), srandomdev(3)
1904 and arc4random(3). The reason for this is that the KERN_ARND
1905 sysctl only returns entropy if it thinks it has some to
1906 share, and with RANDOM_DUMMY or no 'device random' this
1910 An additional fix for the issue described in the 20150614 sendmail
1911 entry below has been committed in revision 284717.
1914 FreeBSD's old make (fmake) has been removed from the system. It is
1915 available as the devel/fmake port or via pkg install fmake.
1918 The fix for the issue described in the 20150614 sendmail entry
1919 below has been committed in revision 284436. The work
1920 around described in that entry is no longer needed unless the
1921 default setting is overridden by a confDH_PARAMETERS configuration
1922 setting of '5' or pointing to a 512 bit DH parameter file.
1925 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
1926 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
1927 and devel/kyua to version 0.20+ and adjust any calling code to work
1928 with Kyuafile and kyua.
1931 The import of openssl to address the FreeBSD-SA-15:10.openssl
1932 security advisory includes a change which rejects handshakes
1933 with DH parameters below 768 bits. sendmail releases prior
1934 to 8.15.2 (not yet released), defaulted to a 512 bit
1935 DH parameter setting for client connections. To work around
1936 this interoperability, sendmail can be configured to use a
1937 2048 bit DH parameter by:
1939 1. Edit /etc/mail/`hostname`.mc
1940 2. If a setting for confDH_PARAMETERS does not exist or
1941 exists and is set to a string beginning with '5',
1942 replace it with '2'.
1943 3. If a setting for confDH_PARAMETERS exists and is set to
1944 a file path, create a new file with:
1945 openssl dhparam -out /path/to/file 2048
1946 4. Rebuild the .cf file:
1947 cd /etc/mail/; make; make install
1948 5. Restart sendmail:
1949 cd /etc/mail/; make restart
1951 A sendmail patch is coming, at which time this file will be
1955 Generation of legacy formatted entries have been disabled by default
1956 in pwd_mkdb(8), as all base system consumers of the legacy formatted
1957 entries were converted to use the new format by default when the new,
1958 machine independent format have been added and supported since FreeBSD
1961 Please see the pwd_mkdb(8) manual page for further details.
1964 Clang and llvm have been upgraded to 3.6.1 release. Please see the
1965 20141231 entry below for information about prerequisites and upgrading,
1966 if you are not already using 3.5.0 or higher.
1969 TI platform code switched to using vendor DTS files and this update
1970 may break existing systems running on Beaglebone, Beaglebone Black,
1973 - dtb files should be regenerated/reinstalled. Filenames are the
1974 same but content is different now
1975 - GPIO addressing was changed, now each GPIO bank (32 pins per bank)
1976 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
1977 addressing scheme is now pin 25 on /dev/gpioc3.
1978 - Pandaboard: /etc/ttys should be updated, serial console device is
1979 now /dev/ttyu2, not /dev/ttyu0
1982 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
1983 If you need the GNU extension from groff soelim(1), install groff
1984 from package: pkg install groff, or via ports: textproc/groff.
1987 chmod, chflags, chown and chgrp now affect symlinks in -R mode as
1988 defined in symlink(7); previously symlinks were silently ignored.
1991 The const qualifier has been removed from iconv(3) to comply with
1992 POSIX. The ports tree is aware of this from r384038 onwards.
1995 Libraries specified by LIBADD in Makefiles must have a corresponding
1996 DPADD_<lib> variable to ensure correct dependencies. This is now
1997 enforced in src.libnames.mk.
2000 From legacy ata(4) driver was removed support for SATA controllers
2001 supported by more functional drivers ahci(4), siis(4) and mvs(4).
2002 Kernel modules ataahci and ataadaptec were removed completely,
2003 replaced by ahci and mvs modules respectively.
2006 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
2007 the 20141231 entry below for information about prerequisites and
2008 upgrading, if you are not already using 3.5.0 or higher.
2011 The 32-bit PowerPC kernel has been changed to a position-independent
2012 executable. This can only be booted with a version of loader(8)
2013 newer than January 31, 2015, so make sure to update both world and
2014 kernel before rebooting.
2017 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
2018 but before r278950, the RNG was not seeded properly. Immediately
2019 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
2020 ssh keys or openssl keys) that were generated w/ a kernel from that
2021 range. This does not affect programs that directly used /dev/random
2022 or /dev/urandom. All userland uses of arc4random(3) are affected.
2025 The autofs(4) ABI was changed in order to restore binary compatibility
2026 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
2027 with the new kernel.
2030 The powerpc64 kernel has been changed to a position-independent
2031 executable. This can only be booted with a new version of loader(8),
2032 so make sure to update both world and kernel before rebooting.
2035 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
2036 only release, no new features have been added. Please see the 20141231
2037 entry below for information about prerequisites and upgrading, if you
2038 are not already using 3.5.0.
2041 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
2042 taken from the ELF Tool Chain project rather than GNU binutils. They
2043 should be drop-in replacements, with the addition of arm64 support.
2044 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
2045 binutils tools, if necessary. See 20150805 for updated information.
2048 The default Unbound configuration now enables remote control
2049 using a local socket. Users who have already enabled the
2050 local_unbound service should regenerate their configuration
2051 by running "service local_unbound setup" as root.
2054 The GNU texinfo and GNU info pages have been removed.
2055 To be able to view GNU info pages please install texinfo from ports.
2058 Clang, llvm and lldb have been upgraded to 3.5.0 release.
2060 As of this release, a prerequisite for building clang, llvm and lldb is
2061 a C++11 capable compiler and C++11 standard library. This means that to
2062 be able to successfully build the cross-tools stage of buildworld, with
2063 clang as the bootstrap compiler, your system compiler or cross compiler
2064 should either be clang 3.3 or later, or gcc 4.8 or later, and your
2065 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
2068 On any standard FreeBSD 10.x or 11.x installation, where clang and
2069 libc++ are on by default (that is, on x86 or arm), this should work out
2072 On 9.x installations where clang is enabled by default, e.g. on x86 and
2073 powerpc, libc++ will not be enabled by default, so libc++ should be
2074 built (with clang) and installed first. If both clang and libc++ are
2075 missing, build clang first, then use it to build libc++.
2077 On 8.x and earlier installations, upgrade to 9.x first, and then follow
2078 the instructions for 9.x above.
2080 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
2081 default, and do not build clang.
2083 Many embedded systems are resource constrained, and will not be able to
2084 build clang in a reasonable time, or in some cases at all. In those
2085 cases, cross building bootable systems on amd64 is a workaround.
2087 This new version of clang introduces a number of new warnings, of which
2088 the following are most likely to appear:
2092 This warns in two cases, for both C and C++:
2093 * When the code is trying to take the absolute value of an unsigned
2094 quantity, which is effectively a no-op, and almost never what was
2095 intended. The code should be fixed, if at all possible. If you are
2096 sure that the unsigned quantity can be safely cast to signed, without
2097 loss of information or undefined behavior, you can add an explicit
2098 cast, or disable the warning.
2100 * When the code is trying to take an absolute value, but the called
2101 abs() variant is for the wrong type, which can lead to truncation.
2102 If you want to disable the warning instead of fixing the code, please
2103 make sure that truncation will not occur, or it might lead to unwanted
2106 -Wtautological-undefined-compare and
2107 -Wundefined-bool-conversion
2109 These warn when C++ code is trying to compare 'this' against NULL, while
2110 'this' should never be NULL in well-defined C++ code. However, there is
2111 some legacy (pre C++11) code out there, which actively abuses this
2112 feature, which was less strictly defined in previous C++ versions.
2114 Squid and openjdk do this, for example. The warning can be turned off
2115 for C++98 and earlier, but compiling the code in C++11 mode might result
2116 in unexpected behavior; for example, the parts of the program that are
2117 unreachable could be optimized away.
2120 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
2121 kernel sources have been removed. The .h files remain, since some
2122 utilities include them. This will need to be fixed later.
2123 If "mount -t oldnfs ..." is attempted, it will fail.
2124 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
2125 the utilities will report errors.
2128 The handling of LOCAL_LIB_DIRS has been altered to skip addition of
2129 directories to top level SUBDIR variable when their parent
2130 directory is included in LOCAL_DIRS. Users with build systems with
2131 such hierarchies and without SUBDIR entries in the parent
2132 directory Makefiles should add them or add the directories to
2136 faith(4) and faithd(8) have been removed from the base system. Faith
2137 has been obsolete for a very long time.
2140 vt(4), the new console driver, is enabled by default. It brings
2141 support for Unicode and double-width characters, as well as
2142 support for UEFI and integration with the KMS kernel video
2145 You may need to update your console settings in /etc/rc.conf,
2146 most probably the keymap. During boot, /etc/rc.d/syscons will
2147 indicate what you need to do.
2149 vt(4) still has issues and lacks some features compared to
2150 syscons(4). See the wiki for up-to-date information:
2151 https://wiki.freebsd.org/Newcons
2153 If you want to keep using syscons(4), you can do so by adding
2154 the following line to /boot/loader.conf:
2158 pjdfstest has been integrated into kyua as an opt-in test suite.
2159 Please see share/doc/pjdfstest/README for more details on how to
2163 gperf has been removed from the base system for architectures
2164 that use clang. Ports that require gperf will obtain it from the
2168 pjdfstest has been moved from tools/regression/pjdfstest to
2172 At svn r271982, The default linux compat kernel ABI has been adjusted
2173 to 2.6.18 in support of the linux-c6 compat ports infrastructure
2174 update. If you wish to continue using the linux-f10 compat ports,
2175 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
2176 encouraged to update their linux-compat packages to linux-c6 during
2177 their next update cycle.
2180 The ofwfb driver, used to provide a graphics console on PowerPC when
2181 using vt(4), no longer allows mmap() of all physical memory. This
2182 will prevent Xorg on PowerPC with some ATI graphics cards from
2183 initializing properly unless x11-servers/xorg-server is updated to
2187 The xdev targets have been converted to using TARGET and
2188 TARGET_ARCH instead of XDEV and XDEV_ARCH.
2191 The default unbound configuration has been modified to address
2192 issues with reverse lookups on networks that use private
2193 address ranges. If you use the local_unbound service, run
2194 "service local_unbound setup" as root to regenerate your
2195 configuration, then "service local_unbound reload" to load the
2199 The GNU texinfo and GNU info pages are not built and installed
2200 anymore, WITH_INFO knob has been added to allow to built and install
2202 UPDATE: see 20150102 entry on texinfo's removal
2205 The GNU readline library is now an INTERNALLIB - that is, it is
2206 statically linked into consumers (GDB and variants) in the base
2207 system, and the shared library is no longer installed. The
2208 devel/readline port is available for third party software that
2212 The Itanium architecture (ia64) has been removed from the list of
2213 known architectures. This is the first step in the removal of the
2217 Commit r268115 has added NFSv4.1 server support, merged from
2218 projects/nfsv4.1-server. Since this includes changes to the
2219 internal interfaces between the NFS related modules, a full
2220 build of the kernel and modules will be necessary.
2221 __FreeBSD_version has been bumped.
2224 The WITHOUT_VT_SUPPORT kernel config knob has been renamed
2225 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
2226 which differs from the behaviour controlled by this knob.)
2229 Maximal length of the serial number in CTL was increased from 16 to
2230 64 chars, that breaks ABI. All CTL-related tools, such as ctladm
2231 and ctld, need to be rebuilt to work with a new kernel.
2234 The libatf-c and libatf-c++ major versions were downgraded to 0 and
2235 1 respectively to match the upstream numbers. They were out of
2236 sync because, when they were originally added to FreeBSD, the
2237 upstream versions were not respected. These libraries are private
2238 and not yet built by default, so renumbering them should be a
2239 non-issue. However, unclean source trees will yield broken test
2240 programs once the operator executes "make delete-old-libs" after a
2241 "make installworld".
2243 Additionally, the atf-sh binary was made private by moving it into
2244 /usr/libexec/. Already-built shell test programs will keep the
2245 path to the old binary so they will break after "make delete-old"
2248 If you are using WITH_TESTS=yes (not the default), wipe the object
2249 tree and rebuild from scratch to prevent spurious test failures.
2250 This is only needed once: the misnumbered libraries and misplaced
2251 binaries have been added to OptionalObsoleteFiles.inc so they will
2252 be removed during a clean upgrade.
2255 Clang and llvm have been upgraded to 3.4.1 release.
2258 We bogusly installed src.opts.mk in /usr/share/mk. This file should
2259 be removed to avoid issues in the future (and has been added to
2263 /etc/src.conf now affects only builds of the FreeBSD src tree. In the
2264 past, it affected all builds that used the bsd.*.mk files. The old
2265 behavior was a bug, but people may have relied upon it. To get this
2266 behavior back, you can .include /etc/src.conf from /etc/make.conf
2267 (which is still global and isn't changed). This also changes the
2268 behavior of incremental builds inside the tree of individual
2269 directories. Set MAKESYSPATH to ".../share/mk" to do that.
2270 Although this has survived make universe and some upgrade scenarios,
2271 other upgrade scenarios may have broken. At least one form of
2272 temporary breakage was fixed with MAKESYSPATH settings for buildworld
2273 as well... In cases where MAKESYSPATH isn't working with this
2274 setting, you'll need to set it to the full path to your tree.
2276 One side effect of all this cleaning up is that bsd.compiler.mk
2277 is no longer implicitly included by bsd.own.mk. If you wish to
2278 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2282 The lindev device has been removed since /dev/full has been made a
2283 standard device. __FreeBSD_version has been bumped.
2286 The knob WITHOUT_VI was added to the base system, which controls
2287 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2288 in order to reorder files share/termcap and didn't build ex(1) as a
2289 build tool, so building/installing with WITH_VI is highly advised for
2290 build hosts for older releases.
2292 This issue has been fixed in stable/9 and stable/10 in r277022 and
2293 r276991, respectively.
2296 The YES_HESIOD knob has been removed. It has been obsolete for
2297 a decade. Please move to using WITH_HESIOD instead or your builds
2298 will silently lack HESIOD.
2301 The uart(4) driver has been changed with respect to its handling
2302 of the low-level console. Previously the uart(4) driver prevented
2303 any process from changing the baudrate or the CLOCAL and HUPCL
2304 control flags. By removing the restrictions, operators can make
2305 changes to the serial console port without having to reboot.
2306 However, when getty(8) is started on the serial device that is
2307 associated with the low-level console, a misconfigured terminal
2308 line in /etc/ttys will now have a real impact.
2309 Before upgrading the kernel, make sure that /etc/ttys has the
2310 serial console device configured as 3wire without baudrate to
2311 preserve the previous behaviour. E.g:
2312 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
2315 Support for libwrap (TCP wrappers) in rpcbind was disabled by default
2316 to improve performance. To re-enable it, if needed, run rpcbind
2317 with command line option -W.
2320 Switched back to the GPL dtc compiler due to updates in the upstream
2321 dts files not being supported by the BSDL dtc compiler. You will need
2322 to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2323 may result while building dtb files during a kernel build if you fail
2324 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
2327 Clang and llvm have been upgraded to 3.4 release.
2330 The nve(4) driver has been removed. Please use the nfe(4) driver
2331 for NVIDIA nForce MCP Ethernet adapters instead.
2334 An ABI incompatibility crept into the libc++ 3.4 import in r261283.
2335 This could cause certain C++ applications using shared libraries built
2336 against the previous version of libc++ to crash. The incompatibility
2337 has now been fixed, but any C++ applications or shared libraries built
2338 between r261283 and r261801 should be recompiled.
2341 OpenSSH will now ignore errors caused by kernel lacking of Capsicum
2342 capability mode support. Please note that enabling the feature in
2343 kernel is still highly recommended.
2346 OpenSSH is now built with sandbox support, and will use sandbox as
2347 the default privilege separation method. This requires Capsicum
2348 capability mode support in kernel.
2351 The libelf and libdwarf libraries have been updated to newer
2352 versions from upstream. Shared library version numbers for
2353 these two libraries were bumped. Any ports or binaries
2354 requiring these two libraries should be recompiled.
2355 __FreeBSD_version is bumped to 1100006.
2358 If a Makefile in a tests/ directory was auto-generating a Kyuafile
2359 instead of providing an explicit one, this would prevent such
2360 Makefile from providing its own Kyuafile in the future during
2361 NO_CLEAN builds. This has been fixed in the Makefiles but manual
2362 intervention is needed to clean an objdir if you use NO_CLEAN:
2363 # find /usr/obj -name Kyuafile | xargs rm -f
2366 The behavior of gss_pseudo_random() for the krb5 mechanism
2367 has changed, for applications requesting a longer random string
2368 than produced by the underlying enctype's pseudo-random() function.
2369 In particular, the random string produced from a session key of
2370 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
2371 be different at the 17th octet and later, after this change.
2372 The counter used in the PRF+ construction is now encoded as a
2373 big-endian integer in accordance with RFC 4402.
2374 __FreeBSD_version is bumped to 1100004.
2377 The WITHOUT_ATF build knob has been removed and its functionality
2378 has been subsumed into the more generic WITHOUT_TESTS. If you were
2379 using the former to disable the build of the ATF libraries, you
2380 should change your settings to use the latter.
2383 The default version of mtree is nmtree which is obtained from
2384 NetBSD. The output is generally the same, but may vary
2385 slightly. If you found you need identical output adding
2386 "-F freebsd9" to the command line should do the trick. For the
2387 time being, the old mtree is available as fmtree.
2390 libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
2391 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
2392 1.1.4_8 and verify bsdyml not linked in, before running "make
2394 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
2396 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
2399 The stable/10 branch has been created in subversion from head
2406 Sometimes, obscure build problems are the result of environment
2407 poisoning. This can happen because the make utility reads its
2408 environment when searching for values for global variables. To run
2409 your build attempts in an "environmental clean room", prefix all make
2410 commands with 'env -i '. See the env(1) manual page for more details.
2411 Occasionally a build failure will occur with "make -j" due to a race
2412 condition. If this happens try building again without -j, and please
2413 report a bug if it happens consistently.
2415 When upgrading from one major version to another it is generally best to
2416 upgrade to the latest code in the currently installed branch first, then
2417 do an upgrade to the new branch. This is the best-tested upgrade path,
2418 and has the highest probability of being successful. Please try this
2419 approach if you encounter problems with a major version upgrade. Since
2420 the stable 4.x branch point, one has generally been able to upgrade from
2421 anywhere in the most recent stable branch to head / current (or even the
2422 last couple of stable branches). See the top of this file when there's
2425 The update process will emit an error on an attempt to perform a build
2426 or install from a FreeBSD version below the earliest supported version.
2427 When updating from an older version the update should be performed one
2428 major release at a time, including running `make delete-old` at each
2431 When upgrading a live system, having a root shell around before
2432 installing anything can help undo problems. Not having a root shell
2433 around can lead to problems if pam has changed too much from your
2434 starting point to allow continued authentication after the upgrade.
2436 This file should be read as a log of events. When a later event changes
2437 information of a prior event, the prior event should not be deleted.
2438 Instead, a pointer to the entry with the new information should be
2439 placed in the old entry. Readers of this file should also sanity check
2440 older entries before relying on them blindly. Authors of new entries
2441 should write them with this in mind.
2445 When upgrading the boot ZFS pool to a new version, always follow
2448 1.) recompile and reinstall the ZFS boot loader and boot block
2449 (this is part of "make buildworld" and "make installworld")
2451 2.) update the ZFS boot block on your boot drive
2453 The following example updates the ZFS boot block on the
2454 freebsd-boot partition of a GPT partitioned drive ada0:
2455 "gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2456 The value $N will typically be 1 (if booting from BIOS) or 2 (if
2459 Non-boot pools do not need these updates.
2463 If you are updating from a prior version of FreeBSD (even one just
2464 a few days old), you should follow this procedure. It is the most
2465 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
2467 make kernel-toolchain
2468 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
2469 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
2471 To test a kernel once
2472 ---------------------
2473 If you just want to boot a kernel once (because you are not sure
2474 if it works, or if you want to boot a known bad kernel to provide
2475 debugging information) run
2476 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
2477 nextboot -k testkernel
2479 To rebuild everything and install it on the current system.
2480 -----------------------------------------------------------
2481 # Note: sometimes if you are running current you gotta do more than
2482 # is listed here if you are upgrading from a really old current.
2484 <make sure you have good level 0 dumps>
2486 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2487 make installkernel KERNCONF=YOUR_KERNEL_HERE
2489 <reboot in single user> [3]
2496 To cross-install current onto a separate partition
2497 --------------------------------------------------
2498 # In this approach we use a separate partition to hold
2499 # current's root, 'usr', and 'var' directories. A partition
2500 # holding "/", "/usr" and "/var" should be about 2GB in
2503 <make sure you have good level 0 dumps>
2506 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2507 <maybe newfs current's root partition>
2508 <mount current's root partition on directory ${CURRENT_ROOT}>
2509 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
2510 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
2511 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
2512 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
2513 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
2514 <reboot into current>
2515 <do a "native" rebuild/install as described in the previous section>
2516 <maybe install compatibility libraries from ports/misc/compat*>
2520 To upgrade in-place from stable to current
2521 ----------------------------------------------
2522 <make sure you have good level 0 dumps>
2524 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
2525 make installkernel KERNCONF=YOUR_KERNEL_HERE
2527 <reboot in single user> [3]
2534 Make sure that you've read the UPDATING file to understand the
2535 tweaks to various things you need. At this point in the life
2536 cycle of current, things change often and you are on your own
2537 to cope. The defaults can also change, so please read ALL of
2538 the UPDATING entries.
2540 Also, if you are tracking -current, you must be subscribed to
2541 freebsd-current@freebsd.org. Make sure that before you update
2542 your sources that you have read and understood all the recent
2543 messages there. If in doubt, please track -stable which has
2544 much fewer pitfalls.
2546 [1] If you have third party modules, such as vmware, you should disable
2547 them at this point so they don't crash your system on
2548 reboot. Alternatively, you should rebuild all the modules you have in
2549 your system and install them as well. If you are running -current, you
2550 should seriously consider placing all sources to all the modules for
2551 your system (or symlinks to them) in /usr/local/sys/modules so this
2552 happens automatically. If all your modules come from ports, then adding
2553 the port origin directories to PORTS_MODULES instead is also automatic
2555 PORTS_MODULES+=x11/nvidia-driver
2557 [3] From the bootblocks, boot -s, and then do
2561 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed
2562 cd src # full path to source
2563 adjkerntz -i # if CMOS is wall time
2564 Also, when doing a major release upgrade, it is required that you boot
2565 into single user mode to do the installworld.
2567 [4] Note: This step is non-optional. Failure to do this step
2568 can result in a significant reduction in the functionality of the
2569 system. Attempting to do it by hand is not recommended and those
2570 that pursue this avenue should read this file carefully, as well
2571 as the archives of freebsd-current and freebsd-hackers mailing lists
2572 for potential gotchas. The -U option is also useful to consider.
2573 See mergemaster(8) for more information.
2575 [5] Usually this step is a no-op. However, from time to time
2576 you may need to do this if you get unknown user in the following
2577 step. It never hurts to do it all the time. You may need to
2578 install a new mergemaster (cd src/usr.sbin/mergemaster && make
2579 install) after the buildworld before this step if you last updated
2580 from current before 20130425 or from -stable before 20130430.
2582 [6] This only deletes old files and directories. Old libraries
2583 can be deleted by "make delete-old-libs", but you have to make
2584 sure that no program is using those libraries anymore.
2586 [8] The new kernel must be able to run existing binaries used by an
2587 installworld. When upgrading across major versions, the new kernel's
2588 configuration must include the correct COMPAT_FREEBSD<n> option for
2589 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure
2590 to do so may leave you with a system that is hard to boot to recover. A
2591 GENERIC kernel will include suitable compatibility options to run
2592 binaries from older branches. Note that the ability to run binaries
2593 from unsupported branches is not guaranteed.
2595 Make sure that you merge any new devices from GENERIC since the
2596 last time you updated your kernel config file. Options also
2597 change over time, so you may need to adjust your custom kernels
2600 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2601 "?=" instead of the "=" assignment operator, so that buildworld can
2602 override the CPUTYPE if it needs to.
2604 MAKEOBJDIRPREFIX must be defined in an environment variable, and
2605 not on the command line, or in /etc/make.conf. buildworld will
2606 warn if it is improperly defined.
2609 This file contains a list, in reverse chronological order, of major
2610 breakages in tracking -current. It is not guaranteed to be a complete
2611 list of such breakages, and only contains entries since September 23, 2011.
2612 If you need to see UPDATING entries from before that date, you will need
2613 to fetch an UPDATING file from an older FreeBSD release.
