213 Various LinuxKPI functionality was added which conflicts with DRM.
214 Please update your drm-kmod port to after the __FreeBSD_verison 1300139
218 The stable/13 branch has been created from main.
221 PC Card attachments for all devices have been removed. In the case of
222 wi and cmx, the entire drivers were removed because they were only
223 PC Card devices. FreeBSD_version 1300134 should be used for this
224 since it was bumped so recently.
227 Transport-independent parts of HID support have been split off the USB
228 code in to separate subsystem. Kernel configs which include one of
229 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
230 be updated with adding of "device hid" line.
233 ncurses installation has been modified to only keep the widechar
234 enabled version. Incremental build is broken for that change, so it
235 requires a clean build.
238 The FreeBSD project has migrated from Subversion to Git. Temporary
239 instructions can be found at
240 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
241 and other documents in that repo.
244 The services database has been updated to cover more of the basic
245 services expected in a modern system. The database is big enough
246 that it will cause issues in mergemaster in Releases previous to
247 12.2 and 11.3, or in very old current systems from before r358154.
250 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
251 may be installed from ports or packages.
254 ping6 has been merged into ping. It can now be called as "ping -6".
255 See ping(8) for details.
258 Default value of net.add_addr_allfibs has been changed to 0.
259 If you have multi-fib configuration and rely on existence of all
260 interface routes in every fib, you need to set the above sysctl to 1.
262 The internal pre-processor in the calendar(1) program has been
263 extended to support more C pre-processor commands (e.g. #ifdef, #else,
264 and #undef) and to detect unbalanced conditional statements.
265 Error messages have been extended to include the filename and line
266 number if processing stops to help fixing malformed data files.
269 All the data files for the calendar(1) program, except calendar.freebsd,
270 have been moved to the deskutils/calendar-data port, much like the
271 jewish calendar entries were moved to deskutils/hebcal years ago. After
272 make delete-old-files, you need to install it to retain full
273 functionality. calendar(1) will issue a reminder for files it can't
277 LINT files are no longer generated. We now include the relevant NOTES
278 files. Note: This may cause conflicts with updating in some cases.
279 find sys -name LINT\* -delete
280 is suggested across this commit to remove the generated LINT files.
282 If you have tried to update with generated files there, the svn
283 command you want to un-auger the tree is
286 and then do the above find from the top level. Substitute 'amd64'
287 above with where the error message indicates a conflict.
290 OpenZFS support has been integrated. Do not upgrade root pools until
291 the loader is updated to support zstd. Furthermore, we caution against
292 'zpool upgrade' for the next few weeks. The change should be transparent
293 unless you want to use new features.
295 Not all "NO_CLEAN" build scenarios work across these changes. Many
296 scenarios have been tested and fixed, but rebuilding kernels without
297 rebuilding world may fail.
299 The ZFS cache file has moved from /boot to /etc to match the OpenZFS
300 upstream default. A fallback to /boot has been added for mountroot.
302 Pool auto import behavior at boot has been moved from the kernel module
303 to an explicit "zpool import -a" in one of the rc scripts enabled by
304 zfs_enable=YES. This means your non-root zpools won't auto import until
305 you upgrade your /etc/rc.d files.
308 The resume code now notifies devd with the 'kernel' system
309 rather than the old 'kern' subsystem to be consistent with
310 other use. The old notification will be created as well, but
311 will be removed prior to FreeBSD 14.0.
314 r362275 changed the internal API between the kernel RPC and the
315 NFS modules. As such, all the modules must be recompiled from
319 r364330 modified the internal API used between the NFS modules.
320 As such, all the NFS modules must be re-compiled from sources.
323 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
324 been upgraded to 11.0.0. Please see the 20141231 entry below for
325 information about prerequisites and upgrading, if you are not already
326 using clang 3.5.0 or higher.
329 r364092 modified the internal ABI used between the kernel NFS
330 modules. As such, all of these modules need to be rebuilt
331 from sources, so a version bump was done.
334 Makefile.inc has been updated to work around the issue documented in
335 20200729. It was a case where the optimization of using symbolic links
336 to point to binaries created a situation where we'd run new binaries
337 with old libraries starting midway through the installworld process.
340 r363679 has redefined some undefined behavior in regcomp(3); notably,
341 extraneous escapes of most ordinary characters will no longer be
342 accepted. An exp-run has identified all of the problems with this in
343 ports, but other non-ports software may need extra escapes removed to
344 continue to function.
346 Because of this change, installworld may encounter the following error
347 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
348 you do not halt installworld. Instead, let it run to completion (whether
349 successful or not) and run installworld once more.
352 A new implementation of bc and dc has been imported in r362681. This
353 implementation corrects non-conformant behavior of the previous bc
354 and adds GNU bc compatible options. It offers a number of extensions,
355 is much faster on large values, and has support for message catalogs
356 (a number of languages are already supported, contributions of further
357 languages welcome). The option WITHOUT_GH_BC can be used to build the
358 world with the previous versions of bc and dc.
361 r362639 changed the internal API used between the NFS kernel modules.
362 As such, they all need to be rebuilt from sources.
365 r362158 changed the arguments for VFS_CHECKEXP(). As such, any
366 out of tree file systems need to be modified and rebuilt.
367 Also, any file systems that are modules must be rebuilt.
370 read(2) of a directory fd is now rejected by default. root may
371 re-enable it for system root only on non-ZFS filesystems with the
372 security.bsd.allow_read_dir sysctl(8) MIB if
373 security.bsd.suser_enabled=1.
375 It may be advised to setup aliases for grep to default to `-d skip` if
376 commonly non-recursively grepping a list that includes directories and
377 the potential for the resulting stderr output is not tolerable. Example
378 aliases are now installed, commented out, in /root/.cshrc and
382 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
383 been upgraded to 10.0.1. Please see the 20141231 entry below for
384 information about prerequisites and upgrading, if you are not already
385 using clang 3.5.0 or higher.
388 Support for obsolete compilers has been removed from the build system.
389 Clang 6 and GCC 6.4 are the minimum supported versions.
392 closefrom(2) has been moved under COMPAT12, and replaced in libc with a
393 stub that calls close_range(2). If using a custom kernel configuration,
394 you may want to ensure that the COMPAT_FREEBSD12 option is included, as
395 a slightly older -CURRENT userland and older FreeBSD userlands may not
396 be functional without closefrom(2).
399 Upstream DTS from Linux 5.6 was merged and they now have the SID
400 and THS (Secure ID controller and THermal Sensor) node present.
401 The DTB overlays have now been removed from the tree for the H3/H5 and
402 A64 SoCs and the aw_sid and aw_thermal driver have been updated to
403 deal with upstream DTS. If you are using those overlays you need to
404 remove them from loader.conf and update the DTBs on the FAT partition.
407 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
408 been upgraded to 10.0.0. Please see the 20141231 entry below for
409 information about prerequisites and upgrading, if you are not already
410 using clang 3.5.0 or higher.
413 The amd(8) automount daemon has been removed from the source tree.
414 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
415 amd is still available in the sysutils/am-utils port.
418 Removed brooktree driver (bktr.4) from the tree.
421 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
422 compiler in usr.bin/dtc is used on all architectures which use dtc, and
423 the GPL dtc is available (if needed) from the sysutils/dtc port.
426 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
427 is used by all supported CPU architectures.
430 GCC 4.2.1 has been removed from the tree. The WITH_GCC,
431 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
432 Users who wish to build FreeBSD with GCC must use the external toolchain
436 ncurses has been updated to a newer version (6.2-20200215). Given the ABI
437 has changed, users will have to rebuild all the ports that are linked to
441 The size of struct vnet and the magic cookie have changed.
442 Users need to recompile libkvm and all modules using VIMAGE
443 together with their new kernel.
446 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
447 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
448 your Makefiles and scripts to define MK_<var>=no instead as required.
450 One exception to this is that program or library Makefiles should
451 define MAN to empty rather than setting MK_MAN=no.
454 Clang/LLVM is now the default compiler and LLD the default
458 make universe no longer uses GCC 4.2.1 on any architectures.
459 Architectures not supported by in-tree Clang/LLVM require an
460 external toolchain package.
463 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
464 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
465 options default to off for all supported CPU architectures. As a
466 short-term transition aid they may be enabled via WITH_* options.
467 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
470 Support for armv5 has been disconnected and is being removed. The
471 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
472 You must now use a MACHINE_ARCH of armv6 or armv7. The default
473 MACHINE_ARCH for MACHINE=arm is now armv7.
476 Clang/LLVM is now the default compiler for all powerpc architectures.
477 LLD is now the default linker for powerpc64. The change for powerpc64
478 also includes a change to the ELFv2 ABI, incompatible with the existing
482 Kernel-loadable random(4) modules are no longer unloadable.
485 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
486 been upgraded to 9.0.1. Please see the 20141231 entry below for
487 information about prerequisites and upgrading, if you are not already
488 using clang 3.5.0 or higher.
491 r355677 has modified the internal interface used between the
492 NFS modules in the kernel. As such, they must all be upgraded
493 simultaneously. I will do a version bump for this.
496 The root certificates of the Mozilla CA Certificate Store have been
497 imported into the base system and can be managed with the certctl(8)
498 utility. If you have installed the security/ca_root_nss port or package
499 with the ETCSYMLINK option (the default), be advised that there may be
500 differences between those included in the port and those included in
501 base due to differences in nss branch used as well as general update
502 frequency. Note also that certctl(8) cannot manage certs in the
503 format used by the security/ca_root_nss port.
506 The amd(8) automount daemon has been disabled by default, and will be
507 removed in the future. As of FreeBSD 10.1 the autofs(5) is available
511 The nctgpio and wbwd drivers have been moved to the superio bus.
512 If you have one of these drivers in a kernel configuration, then
513 you should add device superio to it. If you use one of these drivers
514 as a module and you compile a custom set of modules, then you should
515 add superio to the set.
518 KPIs for network drivers to access interface addresses have changed.
519 Users need to recompile NIC driver modules together with kernel.
522 The net.link.tap.user_open sysctl no longer prevents user opening of
523 already created /dev/tapNN devices. Access is still controlled by
524 node permissions, just like tun devices. The net.link.tap.user_open
525 sysctl is now used only to allow users to perform devfs cloning of
526 tap devices, and the subsequent open may not succeed if the user is not
527 in the appropriate group. This sysctl may be deprecated/removed
528 completely in the future.
531 mips, powerpc, and sparc64 are no longer built as part of
532 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
533 not defined, mips, powerpc, and sparc64 builds will look for
534 the xtoolchain binaries and if installed use them for universe
535 builds. As llvm 9.0 becomes vetted for these architectures, they
536 will be removed from the list.
539 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
540 been upgraded to 9.0.0. Please see the 20141231 entry below for
541 information about prerequisites and upgrading, if you are not already
542 using clang 3.5.0 or higher.
545 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
546 GENERIC. They are available as modules and can be loaded by adding
547 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
548 hptnr_load="YES", or hptrr_load="YES", respectively.
551 ntpd no longer by default locks its pages in memory, allowing them
552 to be paged out by the kernel. Use rlimit memlock to restore
553 historic BSD behaviour. For example, add "rlimit memlock 32"
554 to ntp.conf to lock up to 32 MB of ntpd address space in memory.
557 Several of ping6's options have been renamed for better consistency
558 with ping. If you use any of -ARWXaghmrtwx, you must update your
559 scripts. See ping6(8) for details.
562 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
563 and the "-o sync_unmount" and "-o init_backgrounded" mount options have
564 been removed from mount_fusefs(8). You can safely remove them from
565 your scripts, because they had no effect.
567 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
568 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
569 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
570 sysctls have been removed. If you felt the need to set any of them to
571 a non-default value, please tell asomers@FreeBSD.org why.
574 Default permissions on the /var/account/acct file (and copies of it
575 rotated by periodic daily scripts) are changed from 0644 to 0640
576 because the file contains sensitive information that should not be
577 world-readable. If the /var/account directory must be created by
578 rc.d/accounting, the mode used is now 0750. Admins who use the
579 accounting feature are encouraged to change the mode of an existing
580 /var/account directory to 0750 or 0700.
583 Entropy collection and the /dev/random device are no longer optional
584 components. The "device random" option has been removed.
585 Implementations of distilling algorithms can still be made loadable
586 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
589 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
590 been upgraded to 8.0.1. Please see the 20141231 entry below for
591 information about prerequisites and upgrading, if you are not already
592 using clang 3.5.0 or higher.
595 A fix was applied to i386 kernel modules to avoid panics with
596 dpcpu or vnet. Users need to recompile i386 kernel modules
597 having pcpu or vnet sections or they will refuse to load.
600 User-wired pages now have their own counter,
601 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
602 to vm.max_user_wired and changed from an unsigned int to an unsigned
603 long. bhyve VMs wired with the -S are now subject to the user
604 wiring limit; the vm.max_user_wired sysctl may need to be tuned to
605 avoid running into the limit.
608 The IPSEC option has been removed from GENERIC. Users requiring
609 ipsec(4) must now load the ipsec(4) kernel module.
612 The tap(4) driver has been folded into tun(4), and the module has been
613 renamed to tuntap. You should update any kld_list="if_tap" or
614 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
615 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
616 module instead, and "device tap" or "device tun" entries in kernel
617 config files to select the tuntap device instead.
620 The following knobs have been added related to tradeoffs between
621 safe use of the random device and availability in the absence of
624 kern.random.initial_seeding.bypass_before_seeding: tunable; set
625 non-zero to bypass the random device prior to seeding, or zero to
626 block random requests until the random device is initially seeded.
627 For now, set to 1 (unsafe) by default to restore pre-r346250 boot
628 availability properties.
630 kern.random.initial_seeding.read_random_bypassed_before_seeding:
631 read-only diagnostic sysctl that is set when bypass is enabled and
632 read_random(9) is bypassed, to enable programmatic handling of this
633 initial condition, if desired.
635 kern.random.initial_seeding.arc4random_bypassed_before_seeding:
636 Similar to the above, but for for arc4random(9) initial seeding.
638 kern.random.initial_seeding.disable_bypass_warnings: tunable; set
639 non-zero to disable warnings in dmesg when the same conditions are
640 met as for the diagnostic sysctls above. Defaults to zero, i.e.,
641 produce warnings in dmesg when the conditions are met.
644 The loadable random module KPI has changed; the random_infra_init()
645 routine now requires a 3rd function pointer for a bool (*)(void)
646 method that returns true if the random device is seeded (and
647 therefore unblocked).
650 r345895 reverts r320698. This implies that an nfsuserd(8) daemon
651 built from head sources between r320757 (July 6, 2017) and
652 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
653 is added to the command line.
654 nfsuserd daemons built from head sources that are post-r338192 are
655 not affected and should continue to work.
658 The fuse(4) module has been renamed to fusefs(4) for consistency with
659 other filesystems. You should update any kld_load="fuse" entries in
660 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
661 "options FUSE" entries in kernel config files.
664 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
665 8.0.0. Please see the 20141231 entry below for information about
666 prerequisites and upgrading, if you are not already using clang 3.5.0
670 geom_uzip(4) depends on the new module xz. If geom_uzip is statically
671 compiled into your custom kernel, add 'device xz' statement to the
675 drm and drm2 have been removed from the tree. Please see
676 https://wiki.freebsd.org/Graphics for the latest information on
677 migrating to the drm ports.
680 Iflib is no longer unconditionally compiled into the kernel. Drivers
681 using iflib and statically compiled into the kernel, now require
682 the 'device iflib' config option. For the same drivers loaded as
683 modules on kernels not having 'device iflib', the iflib.ko module
684 is loaded automatically.
687 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
688 options no longer exist since r343219 and r343427 respectively;
689 nothing uses them, so they should be just removed from custom
693 r342635 changes the way efibootmgr(8) works by requiring users to add
694 the -b (bootnum) parameter for commands where the bootnum was previously
695 specified with each option. For example 'efibootmgr -B 0001' is now
696 'efibootmgr -B -b 0001'.
699 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
700 in the same as it is applied to NFSv2 and 3. This implies that NFSv4
701 servers that have vfs.nfsd.nfs_privport set will only allow mounts
702 from clients using a reserved port#. Since both the FreeBSD and Linux
703 NFSv4 clients use reserved port#s by default, this should not affect
707 The XLP config has been removed. We can't support 64-bit atomics in this
708 kernel because it is running in 32-bit mode. XLP users must transition
709 to running a 64-bit kernel (XLP64 or XLPN32).
711 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
712 the preferred emulator today and we don't need two different ones.
714 The old sibyte / swarm / Broadcom BCM1250 support has been
715 removed from the mips port.
718 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
719 7.0.1. Please see the 20141231 entry below for information about
720 prerequisites and upgrading, if you are not already using clang 3.5.0
724 Remove the timed and netdate programs from the base tree. Setting
725 the time with these daemons has been obsolete for over a decade.
728 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
729 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
730 it produces broken binaries when ifuncs are in use. Users needing
731 GNU ld should install the binutils port or package.
734 The BSD crtbegin and crtend code has been enabled by default. It has
735 had extensive testing on amd64, arm64, and i386. It can be disabled
736 by building a world with -DWITHOUT_BSD_CRTBEGIN.
739 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
740 has been converted to a port (misc/ctm) and will be removed from
741 FreeBSD-13. It is available as a package (ctm) for all supported
745 The default newsyslog.conf(5) file has been changed to only include
746 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
747 the filenames end in '.conf' and do not begin with a '.'.
749 You should check the configuration files in these two directories match
750 this naming convention. You can verify which configuration files are
751 being included using the command:
755 Ports for the DRM modules have been simplified. Now, amd64 users should
756 just install the drm-kmod port. All others should install
759 Graphics hardware that's newer than about 2010 usually works with
760 drm-kmod. For hardware older than 2013, however, some users will need
761 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
762 than 2008 usually only works in drm-legacy-kmod. The graphics team can
763 only commit to hardware made since 2013 due to the complexity of the
764 market and difficulty to test all the older cards effectively. If you
765 have hardware supported by drm-kmod, you are strongly encouraged to use
766 that as you will get better support.
768 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
769 elsewhere, the drm and drm2 modules will be eliminated from the src base
770 soon (with a limited exception for arm). Please update to the package
771 asap and report any issues to x11@freebsd.org.
773 Generally, anybody using the drm*-kmod packages should add
774 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
775 cross-threading surprises, especially with automatic driver
776 loading from X11 startup. These will become the defaults in 13-current
780 The ixlv(4) driver has been renamed to iavf(4). As a consequence,
781 custom kernel and module loading configuration files must be updated
782 accordingly. Moreover, interfaces previous presented as ixlvN to the
783 system are now exposed as iavfN and network configuration files must
784 be adjusted as necessary.
787 OpenSSL has been updated to version 1.1.1. This update included
788 additional various API changes throughout the base system. It is
789 important to rebuild third-party software after upgrading. The value
790 of __FreeBSD_version has been bumped accordingly.
793 The legacy DRM modules and drivers have now been added to the loader's
794 module blacklist, in favor of loading them with kld_list in rc.conf(5).
795 The module blacklist may be overridden with the loader.conf(5)
796 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
800 The cam(4) based nda(4) driver will be used over nvd(4) by default on
801 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
802 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
803 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
807 Reproducible build mode is now on by default, in preparation for
808 FreeBSD 12.0. This eliminates build metadata such as the user,
809 host, and time from the kernel (and uname), unless the working tree
810 corresponds to a modified checkout from a version control system.
811 The previous behavior can be obtained by setting the /etc/src.conf
812 knob WITHOUT_REPRODUCIBLE_BUILD.
815 The Yarrow CSPRNG has been removed from the kernel as it has not been
816 supported by its designers since at least 2003. Fortuna has been the
817 default since FreeBSD-11.
820 devctl freeze/thaw have gone into the tree, the rc scripts have been
821 updated to use them and devmatch has been changed. You should update
822 kernel, userland and rc scripts all at the same time.
825 The default interpreter has been switched from 4th to Lua.
826 LOADER_DEFAULT_INTERP, documented in build(7), will override the default
827 interpreter. If you have custom FORTH code you will need to set
828 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
829 src.conf for the build. This will create default hard links between
830 loader and loader_4th instead of loader and loader_lua, the new default.
831 If you are using UEFI it will create the proper hard link to loader.efi.
833 bhyve uses userboot.so. It remains 4th-only until some issues are solved
834 regarding coexisting with multiple versions of FreeBSD are resolved.
837 ls(1) now respects the COLORTERM environment variable used in other
838 systems and software to indicate that a colored terminal is both
839 supported and desired. If ls(1) is suddenly emitting colors, they may
840 be disabled again by either removing the unwanted COLORTERM from your
841 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
842 may not be observed in a future release.
845 The default pager for most commands has been changed to "less". To
846 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
850 The jedec_ts(4) driver has been removed. A superset of its functionality
851 is available in the jedec_dimm(4) driver, and the manpage for that
852 driver includes migration instructions. If you have "device jedec_ts"
853 in your kernel configuration file, it must be removed.
856 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
857 This should have no effect if the kernel is booted via BIOS/legacy boot.
858 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
859 has a buggy firmware that prevents a successful boot due to use of
863 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
864 support has been removed from the tree. These ports were
865 obsolete and/or known to be broken for many years.
868 loader.efi has been augmented to participate more fully in the
869 UEFI boot manager protocol. loader.efi will now look at the
870 BootXXXX environment variable to determine if a specific kernel
871 or root partition was specified. XXXX is derived from BootCurrent.
872 efibootmgr(8) manages these standard UEFI variables.
875 zfsloader's functionality has now been folded into loader.
876 zfsloader is no longer necessary once you've updated your
877 boot blocks. For a transition period, we will install a
878 hardlink for zfsloader to loader to allow a smooth transition
879 until the boot blocks can be updated (hard link because old
880 zfs boot blocks don't understand symlinks).
883 ARM64 now have efifb support, if you want to have serial console
884 on your arm64 board when an screen is connected and the bootloader
885 setup a frame buffer for us to use, just add :
889 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
890 an screen connected as the firmware will setup a frame buffer are that
891 u-boot will expose as an EFI frame buffer.
894 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
895 or take steps to update /etc/passwd before doing installworld on
896 existing systems. Do not skip the "mergemaster -Fp" step before
897 installworld, as described in the update procedures near the bottom
898 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
899 if the new mac_ntpd(4) policy is available, unless ntpd_flags or
900 the ntp config file contain options that change file/dir locations.
901 When such options (e.g., "statsdir" or "crypto") are used, ntpd can
902 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
903 taking steps to ensure that all required files/dirs are accessible
907 Big endian arm support has been removed.
910 The static environment setup in kernel configs is no longer mutually
911 exclusive with the loader(8) environment by default. In order to
912 restore the previous default behavior of disabling the loader(8)
913 environment if a static environment is present, you must specify
914 loader_env.disabled=1 in the static environment.
917 The ABI of syscalls used by management tools like sockstat and
918 netstat has been broken to allow 32-bit binaries to work on
919 64-bit kernels without modification. These programs will need
920 to match the kernel in order to function. External programs may
921 require minor modifications to accommodate a change of type in
922 structures from pointers to 64-bit virtual addresses.
925 On i386 and amd64 atomics are now inlined. Out of tree modules using
926 atomics will need to be rebuilt.
929 The '%I' format in the kern.corefile sysctl limits the number of
930 core files that a process can generate to the number stored in the
931 debug.ncores sysctl. The '%I' format is replaced by the single digit
932 index. Previously, if all indexes were taken the kernel would overwrite
933 only a core file with the highest index in a filename.
934 Currently the system will create a new core file if there is a free
935 index or if all slots are taken it will overwrite the oldest one.
938 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
939 6.0.1. Please see the 20141231 entry below for information about
940 prerequisites and upgrading, if you are not already using clang 3.5.0
944 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
945 needed to be changed to work with it. This change was made with r335763
946 and requires a mergemaster / etcupdate / etc to update the installed
950 r334930 changed the interface between the NFS modules, so they all
951 need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
954 As of r334391 lld is the default amd64 system linker; it is installed
955 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
959 The kernel / userland interface for devinfo changed, so you'll
960 need a new kernel and userland as a pair for it to work (rebuilding
961 lib/libdevinfo is all that's required). devinfo and devmatch will
962 not work, but everything else will when there's a mismatch.
965 The on-disk format for hwpmc callchain records has changed to include
966 threadid corresponding to a given record. This changes the field offsets
967 and thus requires that libpmcstat be rebuilt before using a kernel
971 The vxge(4) driver has been removed. This driver was introduced into
972 HEAD one week before the Exar left the Ethernet market and is not
973 known to be used. If you have device vxge in your kernel config file
977 The amd64 kernel now requires a ld that supports ifunc to produce a
978 working kernel, either lld or a newer binutils. lld is built by default
979 on amd64, and the 'buildkernel' target uses it automatically. However,
980 it is not the default linker, so building the kernel the traditional
981 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
982 binutils port/package). lld will soon be default, and this requirement
985 NOTE: As of r334391 lld is the default system linker on amd64, and no
986 workaround is necessary.
989 The nxge(4) driver has been removed. This driver was for PCI-X 10g
990 cards made by s2io/Neterion. The company was acquired by Exar and
991 no longer sells or supports Ethernet products. If you have device
992 nxge in your kernel config file it must be removed.
995 The tz database (tzdb) has been updated to 2018e. This version more
996 correctly models time stamps in time zones with negative DST such as
997 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
998 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
999 time zone abbreviations and the tm_isdst flag.
1002 The ixgb(4) driver has been removed. This driver was for an early and
1003 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
1004 quickly shifted to the long lived ixgbe family. If you have device
1005 ixgb in your kernel config file it must be removed.
1008 The lmc(4) driver has been removed. This was a WAN interface
1009 card that was already reportedly rare in 2003, and had an ambiguous
1010 license. If you have device lmc in your kernel config file it must
1014 Support for Arcnet networks has been removed. If you have device
1015 arcnet or device cm in your kernel config file they must be
1019 Support for FDDI networks has been removed. If you have device
1020 fddi or device fpa in your kernel config file they must be
1024 In addition to supporting RFC 3164 formatted messages, the
1025 syslogd(8) service is now capable of parsing RFC 5424 formatted
1026 log messages. The main benefit of using RFC 5424 is that clients
1027 may now send log messages with timestamps containing year numbers,
1028 microseconds and time zone offsets.
1030 Similarly, the syslog(3) C library function has been altered to
1031 send RFC 5424 formatted messages to the local system logging
1032 daemon. On systems using syslogd(8), this change should have no
1033 negative impact, as long as syslogd(8) and the C library are
1034 updated at the same time. On systems using a different system
1035 logging daemon, it may be necessary to make configuration
1036 adjustments, depending on the software used.
1038 When using syslog-ng, add the 'syslog-protocol' flag to local
1039 input sources to enable parsing of RFC 5424 formatted messages:
1042 unix-dgram("/var/run/log" flags(syslog-protocol));
1045 When using rsyslog, disable the 'SysSock.UseSpecialParser' option
1046 of the 'imuxsock' module to let messages be processed by the
1047 regular RFC 3164/5424 parsing pipeline:
1049 module(load="imuxsock" SysSock.UseSpecialParser="off")
1051 Do note that these changes only affect communication between local
1052 applications and syslogd(8). The format that syslogd(8) uses to
1053 store messages on disk or forward messages to other systems
1054 remains unchanged. syslogd(8) still uses RFC 3164 for these
1055 purposes. Options to customize this behaviour will be added in the
1056 future. Utilities that process log files stored in /var/log are
1057 thus expected to continue to function as before.
1059 __FreeBSD_version has been incremented to 1200061 to denote this
1063 Support for token ring networks has been removed. If you
1064 have "device token" in your kernel config you should remove
1065 it. No device drivers supported token ring.
1068 makefs was modified to be able to tag ISO9660 El Torito boot catalog
1069 entries as EFI instead of overloading the i386 tag as done previously.
1070 The amd64 mkisoimages.sh script used to build amd64 ISO images for
1071 release was updated to use this. This may mean that makefs must be
1072 updated before "make cdrom" can be run in the release directory. This
1073 should be as simple as:
1075 $ cd $SRCDIR/usr.sbin/makefs
1076 $ make depend all install
1079 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
1080 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
1081 Co-existence for the transition period will come shortly. Booting is a
1082 complex environment and test coverage for Lua-enabled loaders has been
1083 thin, so it would be prudent to assume it might not work and make
1084 provisions for backup boot methods.
1087 devmatch functionality has been turned on in devd. It will automatically
1088 load drivers for unattached devices. This may cause unexpected drivers
1089 to be loaded. Please report any problems to current@ and
1093 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
1094 6.0.0. Please see the 20141231 entry below for information about
1095 prerequisites and upgrading, if you are not already using clang 3.5.0
1099 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
1100 This means it is used to link the kernel and userland libraries and
1101 executables, but is not yet installed as /usr/bin/ld by default.
1103 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
1104 WITHOUT_LLD_BOOTSTRAP=yes
1107 On i386, pmtimer has been removed. Its functionality has been folded
1108 into apm. It was a no-op on ACPI in current for a while now (but was
1109 still needed on i386 in FreeBSD 11 and earlier). Users may need to
1110 remove it from kernel config files.
1113 The use of RSS hash from the network card aka flowid has been
1114 disabled by default for lagg(4) as it's currently incompatible with
1115 the lacp and loadbalance protocols.
1117 This can be re-enabled by setting the following in loader.conf:
1118 net.link.lagg.default_use_flowid="1"
1121 The SW_WATCHDOG option is no longer necessary to enable the
1122 hardclock-based software watchdog if no hardware watchdog is
1123 configured. As before, SW_WATCHDOG will cause the software
1124 watchdog to be enabled even if a hardware watchdog is configured.
1127 r326887 fixes the issue described in the 20171214 UPDATING entry.
1128 r326888 flips the switch back to building GELI support always.
1131 r362593 broke ZFS + GELI support for reasons unknown. However,
1132 it also broke ZFS support generally, so GELI has been turned off
1133 by default as the lesser evil in r326857. If you boot off ZFS and/or
1134 GELI, it might not be a good time to update.
1137 PowerPC users must update loader(8) by rebuilding world before
1138 installing a new kernel, as the protocol connecting them has
1139 changed. Without the update, loader metadata will not be passed
1140 successfully to the kernel and users will have to enter their
1141 root partition at the kernel mountroot prompt to continue booting.
1142 Newer versions of loader can boot old kernels without issue.
1145 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
1146 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
1147 to WITH/OUT_LOADER_GELI.
1150 The naive and non-compliant support of posix_fallocate(2) in ZFS
1151 has been removed as of r325320. The system call now returns EINVAL
1152 when used on a ZFS file. Although the new behavior complies with the
1153 standard, some consumers are not prepared to cope with it.
1154 One known victim is lld prior to r325420.
1157 Building in a FreeBSD src checkout will automatically create object
1158 directories now rather than store files in the current directory if
1159 'make obj' was not ran. Calling 'make obj' is no longer necessary.
1160 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
1161 /etc/src-env.conf (not /etc/src.conf), or passing the option in the
1165 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
1166 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
1167 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
1168 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
1169 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
1170 The UNIFIED_OBJDIR option is a transitional feature that will be
1171 removed for 12.0 release; please migrate to the new format for any
1172 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
1173 than hardcoding paths.
1176 The native-xtools target no longer installs the files by default to the
1177 OBJDIR. Use the native-xtools-install target with a DESTDIR to install
1178 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
1181 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
1182 options are changing from controlling the build if defined / undefined
1183 to controlling the build with explicit 'yes' or 'no' values. They will
1184 shift to WITH/WITHOUT options to match other options in the system.
1187 libstand has turned into a private library for sys/boot use only.
1188 It is no longer supported as a public interface outside of sys/boot.
1191 The arm port has split armv6 into armv6 and armv7. armv7 is now
1192 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
1193 and are running a kernel from before r324363, you will need to add
1194 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
1197 When building multiple kernels using KERNCONF, non-existent KERNCONF
1198 files will produce an error and buildkernel will fail. Previously
1199 missing KERNCONF files silently failed giving no indication as to
1200 why, only to subsequently discover during installkernel that the
1201 desired kernel was never built in the first place.
1204 The default serial number format for CTL LUNs has changed. This will
1205 affect users who use /dev/diskid/* device nodes, or whose FibreChannel
1206 or iSCSI clients care about their LUNs' serial numbers. Users who
1207 require serial number stability should hardcode serial numbers in
1211 For 32-bit arm compiled for hard-float support, soft-floating point
1212 binaries now always get their shared libraries from
1213 LD_SOFT_LIBRARY_PATH (in the past, this was only used if
1214 /usr/libsoft also existed). Only users with a hard-float ld.so, but
1215 soft-float everything else should be affected.
1218 The geli password typed at boot is now hidden. To restore the previous
1219 behavior, see geli(8) for configuration options.
1222 Move PMTUD blackhole counters to TCPSTATS and remove them from bare
1223 sysctl values. Minor nit, but requires a rebuild of both world/kernel
1227 "make check" behavior (made in ^/head@r295380) has been changed to
1228 execute from a limited sandbox, as opposed to executing from
1232 - The "beforecheck" and "aftercheck" targets are now specified.
1233 - ${CHECKDIR} (added in commit noted above) has been removed.
1234 - Legacy behavior can be enabled by setting
1235 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
1237 If the limited sandbox mode is enabled, "make check" will execute
1238 "make distribution", then install, execute the tests, and clean up the
1239 sandbox if successful.
1241 The "make distribution" and "make install" targets are typically run as
1242 root to set appropriate permissions and ownership at installation time.
1243 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
1244 environment if executing "make check" with limited sandbox mode using
1245 an unprivileged user.
1248 Since the switch to GPT disk labels, fsck for UFS/FFS has been
1249 unable to automatically find alternate superblocks. As of r322297,
1250 the information needed to find alternate superblocks has been
1251 moved to the end of the area reserved for the boot block.
1252 Filesystems created with a newfs of this vintage or later
1253 will create the recovery information. If you have a filesystem
1254 created prior to this change and wish to have a recovery block
1255 created for your filesystem, you can do so by running fsck in
1256 foreground mode (i.e., do not use the -p or -y options). As it
1257 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
1258 to which you should answer yes.
1261 As of r321665, an NFSv4 server configuration that services
1262 Kerberos mounts or clients that do not support the uid/gid in
1263 owner/owner_group string capability, must explicitly enable
1264 the nfsuserd daemon by adding nfsuserd_enable="YES" to the
1265 machine's /etc/rc.conf file.
1268 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
1269 Please see the 20141231 entry below for information about prerequisites
1270 and upgrading, if you are not already using clang 3.5.0 or higher.
1273 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
1274 r-commands (rlogin, rsh, etc.) to be built with the base system.
1277 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
1278 a very major ABI incompatible change, so users of FreeBSD/powerpc must
1279 be careful when performing source upgrades. It is best to run
1280 'make installworld' from an alternate root system, either a live
1281 CD/memory stick, or a temporary root partition. Additionally, all ports
1282 must be recompiled. powerpc64 is largely unaffected, except in the case
1283 of 32-bit compatibility. All 32-bit binaries will be affected.
1286 Forward compatibility for the "ino64" project have been committed. This
1287 will allow most new binaries to run on older kernels in a limited
1288 fashion. This prevents many of the common foot-shooting actions in the
1289 upgrade as well as the limited ability to roll back the kernel across
1290 the ino64 upgrade. Complicated use cases may not work properly, though
1291 enough simpler ones work to allow recovery in most situations.
1294 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
1295 if you require the GPL compiler.
1298 The internal ABI used for communication between the NFS kernel modules
1299 was changed by r320085, so __FreeBSD_version was bumped to
1300 ensure all the NFS related modules are updated together.
1303 The ABI of struct event was changed by extending the data
1304 member to 64bit and adding ext fields. For upgrade, same
1305 precautions as for the entry 20170523 "ino64" must be
1309 The GNU roff toolchain has been removed from base. To render manpages
1310 which are not supported by mandoc(1), man(1) can fallback on GNU roff
1311 from ports (and recommends to install it).
1312 To render roff(7) documents, consider using GNU roff from ports or the
1313 heirloom doctools roff toolchain from ports via pkg install groff or
1314 via pkg install heirloom-doctools.
1317 The ath(4) and ath_hal(4) modules now build piecemeal to allow for
1318 smaller runtime footprint builds. This is useful for embedded systems
1319 which only require one chipset support.
1321 If you load it as a module, make sure this is in /boot/loader.conf:
1325 This will load the HAL, all chip/RF backends and if_ath_pci.
1326 If you have if_ath_pci in /boot/loader.conf, ensure it is after
1327 if_ath or it will not load any HAL chipset support.
1329 If you want to selectively load things (eg on ye cheape ARM/MIPS
1330 platforms where RAM is at a premium) you should:
1333 * load the chip modules in question
1334 * load ath_rate, ath_dfs
1336 * load if_ath_pci and/or if_ath_ahb depending upon your particular
1337 bus bind type - this is where probe/attach is done.
1339 For further comments/feedback, poke adrian@ .
1342 The "ino64" 64-bit inode project has been committed, which extends
1343 a number of types to 64 bits. Upgrading in place requires care and
1344 adherence to the documented upgrade procedure.
1346 If using a custom kernel configuration ensure that the
1347 COMPAT_FREEBSD11 option is included (as during the upgrade the
1348 system will be running the ino64 kernel with the existing world).
1350 For the safest in-place upgrade begin by removing previous build
1351 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full
1352 procedure documented below under the heading "To rebuild everything and
1353 install it on the current system." Specifically, a reboot is required
1354 after installing the new kernel before installing world. While an
1355 installworld normally works by accident from multiuser after rebooting
1356 the proper kernel, there are many cases where this will fail across this
1357 upgrade and installworld from single user is required.
1360 The NATM framework including the en(4), fatm(4), hatm(4), and
1361 patm(4) devices has been removed. Consumers should plan a
1362 migration before the end-of-life date for FreeBSD 11.
1365 GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1366 diff has not been implemented, if those are needed a newer version of
1367 GNU diff is available via the diffutils package under the gdiff name.
1370 As of r316810 for ipfilter, keep frags is no longer assumed when
1371 keep state is specified in a rule. r316810 aligns ipfilter with
1372 documentation in man pages separating keep frags from keep state.
1373 This allows keep state to be specified without forcing keep frags
1374 and allows keep frags to be specified independently of keep state.
1375 To maintain previous behaviour, also specify keep frags with
1376 keep state (as documented in ipf.conf.5).
1379 arm64 builds now use the base system LLD 4.0.0 linker by default,
1380 instead of requiring that the aarch64-binutils port or package be
1381 installed. To continue using aarch64-binutils, set
1382 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
1385 The UDP optimization in entry 20160818 that added the sysctl
1386 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
1387 packets will no longer be treated as L3 broadcast packets.
1390 Binds and sends to the loopback addresses, IPv6 and IPv4, will now
1391 use any explicitly assigned loopback address available in the jail
1392 instead of using the first assigned address of the jail.
1395 The ctl.ko module no longer implements the iSCSI target frontend:
1396 cfiscsi.ko does instead.
1398 If building cfiscsi.ko as a kernel module, the module can be loaded
1399 via one of the following methods:
1400 - `cfiscsi_load="YES"` in loader.conf(5).
1401 - Add `cfiscsi` to `$kld_list` in rc.conf(5).
1402 - ctladm(8)/ctld(8), when compiled with iSCSI support
1403 (`WITH_ISCSI=yes` in src.conf(5))
1405 Please see cfiscsi(4) for more details.
1408 The mmcsd.ko module now additionally depends on geom_flashmap.ko.
1409 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
1410 same source (previously, the dependency of mmcsd.ko on mmc.ko was
1411 missing, but mmcsd.ko now will refuse to load if it is incompatible
1415 The syntax of ipfw(8) named states was changed to avoid ambiguity.
1416 If you have used named states in the firewall rules, you need to modify
1417 them after installworld and before rebooting. Now named states must
1418 be prefixed with colon.
1421 The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1422 removed as the userland we provide cannot use them. The KMS version
1423 (sys/dev/drm2) supports the same hardware.
1426 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
1427 Please see the 20141231 entry below for information about prerequisites
1428 and upgrading, if you are not already using clang 3.5.0 or higher.
1431 The code that provides support for ZFS .zfs/ directory functionality
1432 has been reimplemented. It's not possible now to create a snapshot
1433 by mkdir under .zfs/snapshot/. That should be the only user visible
1437 EISA bus support has been removed. The WITH_EISA option is no longer
1441 MCA bus support has been removed.
1444 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1445 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
1448 The EM_MULTIQUEUE kernel configuration option is deprecated now that
1449 the em(4) driver conforms to iflib specifications.
1452 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1453 IFLIB. If you have a custom kernel configuration that excludes em(4)
1454 but you use igb(4), you need to re-add em(4) to your custom
1458 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
1459 Please see the 20141231 entry below for information about prerequisites
1460 and upgrading, if you are not already using clang 3.5.0 or higher.
1463 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
1464 Please see the 20141231 entry below for information about prerequisites
1465 and upgrading, if you are not already using clang 3.5.0 or higher.
1468 The layout of the pmap structure has changed for powerpc to put the pmap
1469 statistics at the front for all CPU variations. libkvm(3) and all tools
1470 that link against it need to be recompiled.
1473 isl(4) and cyapa(4) drivers now require a new driver,
1474 chromebook_platform(4), to work properly on Chromebook-class hardware.
1475 On other types of hardware the drivers may need to be configured using
1476 device hints. Please see the corresponding manual pages for details.
1479 The urtwn(4) driver was merged into rtwn(4) and now consists of
1480 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
1482 Also, firmware for RTL8188CE was renamed due to possible name
1483 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
1486 GNU rcs has been removed from base. It is available as packages:
1487 - rcs: Latest GPLv3 GNU rcs version.
1488 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
1492 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1493 modules now requires that the kernel configuration contain the
1494 TCP_HHOOK option. (This option is included in the GENERIC kernel.)
1497 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
1498 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
1501 Relocatable object files with the extension of .So have been renamed
1502 to use an extension of .pico instead. The purpose of this change is
1503 to avoid a name clash with shared libraries on case-insensitive file
1504 systems. On those file systems, foo.So is the same file as foo.so.
1507 GNU rcs has been turned off by default. It can (temporarily) be built
1508 again by adding WITH_RCS knob in src.conf.
1509 Otherwise, GNU rcs is available from packages:
1510 - rcs: Latest GPLv3 GNU rcs version.
1511 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
1514 The backup_uses_rcs functionality has been removed from rc.subr.
1517 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
1518 two separate components, QUEUE_MACRO_DEBUG_TRACE and
1519 QUEUE_MACRO_DEBUG_TRASH. Define both for the original
1520 QUEUE_MACRO_DEBUG behavior.
1523 r304787 changed some ioctl interfaces between the iSCSI userspace
1524 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
1525 rebuilt to work with new kernels. __FreeBSD_version has been bumped
1529 The UDP receive code has been updated to only treat incoming UDP
1530 packets that were addressed to an L2 broadcast address as L3
1531 broadcast packets. It is not expected that this will affect any
1532 standards-conforming UDP application. The new behaviour can be
1533 disabled by setting the sysctl net.inet.udp.require_l2_bcast to
1537 Remove the openbsd_poll system call.
1538 __FreeBSD_version has been bumped because of this.
1541 The stable/11 branch has been created from head@r302406.
1544 The libc stub for the pipe(2) system call has been replaced with
1545 a wrapper that calls the pipe2(2) system call and the pipe(2)
1546 system call is now only implemented by the kernels that include
1547 "options COMPAT_FREEBSD10" in their config file (this is the
1548 default). Users should ensure that this option is enabled in
1549 their kernel or upgrade userspace to r302092 before upgrading their
1553 CAM will now strip leading spaces from SCSI disks' serial numbers.
1554 This will affect users who create UFS filesystems on SCSI disks using
1555 those disk's diskid device nodes. For example, if /etc/fstab
1556 previously contained a line like
1557 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1558 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
1559 transforms like gmirror may also be affected. ZFS users should
1563 The bitstring(3) API has been updated with new functionality and
1564 improved performance. But it is binary-incompatible with the old API.
1565 Objects built with the new headers may not be linked against objects
1566 built with the old headers.
1569 The brk and sbrk functions have been removed from libc on arm64.
1570 Binutils from ports has been updated to not link to these
1571 functions and should be updated to the latest version before
1572 installing a new libc.
1575 The armv6 port now defaults to hard float ABI. Limited support
1576 for running both hardfloat and soft float on the same system
1577 is available using the libraries installed with -DWITH_LIBSOFT.
1578 This has only been tested as an upgrade path for installworld
1579 and packages may fail or need manual intervention to run. New
1580 packages will be needed.
1582 To update an existing self-hosted armv6hf system, you must add
1583 TARGET_ARCH=armv6 on the make command line for both the build
1584 and the install steps.
1587 Kernel modules compiled outside of a kernel build now default to
1588 installing to /boot/modules instead of /boot/kernel. Many kernel
1589 modules built this way (such as those in ports) already overrode
1590 KMODDIR explicitly to install into /boot/modules. However,
1591 manually building and installing a module from /sys/modules will
1592 now install to /boot/modules instead of /boot/kernel.
1595 The CAM I/O scheduler has been committed to the kernel. There should be
1596 no user visible impact. This does enable NCQ Trim on ada SSDs. While the
1597 list of known rogues that claim support for this but actually corrupt
1598 data is believed to be complete, be on the lookout for data
1599 corruption. The known rogue list is believed to be complete:
1601 o Crucial MX100, M550 drives with MU01 firmware.
1602 o Micron M510 and M550 drives with MU01 firmware.
1603 o Micron M500 prior to MU07 firmware
1604 o Samsung 830, 840, and 850 all firmwares
1605 o FCCT M500 all firmwares
1607 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1608 with working NCQ TRIM. For Micron branded drives, see your sales rep for
1609 updated firmware. Black listed drives will work correctly because these
1610 drives work correctly so long as no NCQ TRIMs are sent to them. Given
1611 this list is the same as found in Linux, it's believed there are no
1612 other rogues in the market place. All other models from the above
1615 To be safe, if you are at all concerned, you can quirk each of your
1616 drives to prevent NCQ from being sent by setting:
1617 kern.cam.ada.X.quirks="0x2"
1618 in loader.conf. If the drive requires the 4k sector quirk, set the
1619 quirks entry to 0x3.
1622 The FAST_DEPEND build option has been removed and its functionality is
1623 now the one true way. The old mkdep(1) style of 'make depend' has
1624 been removed. See 20160311 for further details.
1627 Resource range types have grown from unsigned long to uintmax_t. All
1628 drivers, and anything using libdevinfo, need to be recompiled.
1631 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1632 builds. It no longer runs mkdep(1) during 'make depend', and the
1633 'make depend' stage can safely be skipped now as it is auto ran
1634 when building 'make all' and will generate all SRCS and DPSRCS before
1635 building anything else. Dependencies are gathered at compile time with
1636 -MF flags kept in separate .depend files per object file. Users should
1637 run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1638 stale .depend files.
1641 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1642 kernel modules. Therefore, if you load any kernel modules at boot time,
1643 please install the boot loaders after you install the kernel, but before
1647 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1648 make installkernel KERNCONF=YOUR_KERNEL_HERE
1649 make -C sys/boot install
1650 <reboot in single user>
1652 Then follow the usual steps, described in the General Notes section,
1656 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
1657 see the 20141231 entry below for information about prerequisites and
1658 upgrading, if you are not already using clang 3.5.0 or higher.
1661 The AIO subsystem is now a standard part of the kernel. The
1662 VFS_AIO kernel option and aio.ko kernel module have been removed.
1663 Due to stability concerns, asynchronous I/O requests are only
1664 permitted on sockets and raw disks by default. To enable
1665 asynchronous I/O requests on all file types, set the
1666 vfs.aio.enable_unsafe sysctl to a non-zero value.
1669 The ELF object manipulation tool objcopy is now provided by the
1670 ELF Tool Chain project rather than by GNU binutils. It should be a
1671 drop-in replacement, with the addition of arm64 support. The
1672 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1673 to obtain the GNU version if necessary.
1676 Building ZFS pools on top of zvols is prohibited by default. That
1677 feature has never worked safely; it's always been prone to deadlocks.
1678 Using a zvol as the backing store for a VM guest's virtual disk will
1679 still work, even if the guest is using ZFS. Legacy behavior can be
1680 restored by setting vfs.zfs.vol.recursive=1.
1683 The NONE and HPN patches has been removed from OpenSSH. They are
1684 still available in the security/openssh-portable port.
1687 With the addition of ypldap(8), a new _ypldap user is now required
1688 during installworld. "mergemaster -p" can be used to add the user
1689 prior to installworld, as documented in the handbook.
1692 The tftp loader (pxeboot) now uses the option root-path directive. As a
1693 consequence it no longer looks for a pxeboot.4th file on the tftp
1694 server. Instead it uses the regular /boot infrastructure as with the
1698 The code to start recording plug and play data into the modules has
1699 been committed. While the old tools will properly build a new kernel,
1700 a number of warnings about "unknown metadata record 4" will be produced
1701 for an older kldxref. To avoid such warnings, make sure to rebuild
1702 the kernel toolchain (or world). Make sure that you have r292078 or
1703 later when trying to build 292077 or later before rebuilding.
1706 Debug data files are now built by default with 'make buildworld' and
1707 installed with 'make installworld'. This facilitates debugging but
1708 requires more disk space both during the build and for the installed
1709 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1713 r291527 changed the internal interface between the nfsd.ko and
1714 nfscommon.ko modules. As such, they must both be upgraded to-gether.
1715 __FreeBSD_version has been bumped because of this.
1718 Add support for unicode collation strings leads to a change of
1719 order of files listed by ls(1) for example. To get back to the old
1720 behaviour, set LC_COLLATE environment variable to "C".
1722 Databases administrators will need to reindex their databases given
1723 collation results will be different.
1725 Due to a bug in install(1) it is recommended to remove the ancient
1726 locales before running make installworld.
1728 rm -rf /usr/share/locale/*
1731 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
1732 libcrypto.so.7 or libssl.so.7 must be recompiled.
1735 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1736 Kernel modules isp_2400_multi and isp_2500_multi were removed and
1737 should be replaced with isp_2400 and isp_2500 modules respectively.
1740 The build previously allowed using 'make -n' to not recurse into
1741 sub-directories while showing what commands would be executed, and
1742 'make -n -n' to recursively show commands. Now 'make -n' will recurse
1743 and 'make -N' will not.
1746 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1747 and etcupdate will now use this file. A custom sendmail.cf is now
1748 updated via this mechanism rather than via installworld. If you had
1749 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1750 want to remove the exclusion or change it to "always install".
1751 /etc/mail/sendmail.cf is now managed the same way regardless of
1752 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
1753 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1756 Compatibility shims for legacy ATA device names have been removed.
1757 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
1758 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
1759 environment variables, /dev/ad* and /dev/ar* symbolic links.
1762 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
1763 Please see the 20141231 entry below for information about prerequisites
1764 and upgrading, if you are not already using clang 3.5.0 or higher.
1767 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
1768 and renamed from .symbols to .debug. This reduces the size requirements
1769 on the boot partition or file system and provides consistency with
1770 userland debug files.
1772 When using the supported kernel installation method the
1773 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
1774 as is done with /boot/kernel.
1776 Developers wishing to maintain the historical behavior of installing
1777 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
1780 The wireless drivers had undergone changes that remove the 'parent
1781 interface' from the ifconfig -l output. The rc.d network scripts
1782 used to check presence of a parent interface in the list, so old
1783 scripts would fail to start wireless networking. Thus, etcupdate(3)
1784 or mergemaster(8) run is required after kernel update, to update your
1785 rc.d scripts in /etc.
1788 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
1789 These configurations are now automatically interpreted as
1790 'scrub fragment reassemble'.
1793 Kernel-loadable modules for the random(4) device are back. To use
1794 them, the kernel must have
1797 options RANDOM_LOADABLE
1799 kldload(8) can then be used to load random_fortuna.ko
1800 or random_yarrow.ko. Please note that due to the indirect
1801 function calls that the loadable modules need to provide,
1802 the build-in variants will be slightly more efficient.
1804 The random(4) kernel option RANDOM_DUMMY has been retired due to
1805 unpopularity. It was not all that useful anyway.
1808 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
1809 Control over building the ELF Tool Chain tools is now provided by
1810 the WITHOUT_TOOLCHAIN knob.
1813 The polarity of Pulse Per Second (PPS) capture events with the
1814 uart(4) driver has been corrected. Prior to this change the PPS
1815 "assert" event corresponded to the trailing edge of a positive PPS
1816 pulse and the "clear" event was the leading edge of the next pulse.
1818 As the width of a PPS pulse in a typical GPS receiver is on the
1819 order of 1 millisecond, most users will not notice any significant
1820 difference with this change.
1822 Anyone who has compensated for the historical polarity reversal by
1823 configuring a negative offset equal to the pulse width will need to
1824 remove that workaround.
1827 The default group assigned to /dev/dri entries has been changed
1828 from 'wheel' to 'video' with the id of '44'. If you want to have
1829 access to the dri devices please add yourself to the video group
1832 # pw groupmod video -m $USER
1835 The menu.rc and loader.rc files will now be replaced during
1836 upgrades. Please migrate local changes to menu.rc.local and
1837 loader.rc.local instead.
1840 GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1841 strings and strip have been removed. The src.conf(5) knob
1842 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1845 As ZFS requires more kernel stack pages than is the default on some
1846 architectures e.g. i386, it now warns if KSTACK_PAGES is less than
1847 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
1849 Please consider using 'options KSTACK_PAGES=X' where X is greater
1850 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
1853 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
1854 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1855 default, i.e., they will not contain "::". For example, instead
1856 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
1857 to have a more specific match, such as different map entries for
1858 IPv6:0:0 vs IPv6:0. This change requires that configuration
1859 data (including maps, files, classes, custom ruleset, etc.) must
1860 use the same format, so make certain such configuration data is
1861 upgrading. As a very simple check search for patterns like
1862 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
1863 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1864 the cf option UseCompressedIPv6Addresses.
1867 The default kernel entropy-processing algorithm is now
1868 Fortuna, replacing Yarrow.
1870 Assuming you have 'device random' in your kernel config
1871 file, the configurations allow a kernel option to override
1872 this default. You may choose *ONE* of:
1874 options RANDOM_YARROW # Legacy /dev/random algorithm.
1875 options RANDOM_DUMMY # Blocking-only driver.
1877 If you have neither, you get Fortuna. For most people,
1878 read no further, Fortuna will give a /dev/random that works
1879 like it always used to, and the difference will be irrelevant.
1881 If you remove 'device random', you get *NO* kernel-processed
1882 entropy at all. This may be acceptable to folks building
1883 embedded systems, but has complications. Carry on reading,
1884 and it is assumed you know what you need.
1886 *PLEASE* read random(4) and random(9) if you are in the
1887 habit of tweaking kernel configs, and/or if you are a member
1888 of the embedded community, wanting specific and not-usual
1889 behaviour from your security subsystems.
1891 NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1892 random', you will NOT have a functioning /dev/random, and
1893 many cryptographic features will not work, including SSH.
1894 You may also find strange behaviour from the random(3) set
1895 of library functions, in particular sranddev(3), srandomdev(3)
1896 and arc4random(3). The reason for this is that the KERN_ARND
1897 sysctl only returns entropy if it thinks it has some to
1898 share, and with RANDOM_DUMMY or no 'device random' this
1902 An additional fix for the issue described in the 20150614 sendmail
1903 entry below has been committed in revision 284717.
1906 FreeBSD's old make (fmake) has been removed from the system. It is
1907 available as the devel/fmake port or via pkg install fmake.
1910 The fix for the issue described in the 20150614 sendmail entry
1911 below has been committed in revision 284436. The work
1912 around described in that entry is no longer needed unless the
1913 default setting is overridden by a confDH_PARAMETERS configuration
1914 setting of '5' or pointing to a 512 bit DH parameter file.
1917 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
1918 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
1919 and devel/kyua to version 0.20+ and adjust any calling code to work
1920 with Kyuafile and kyua.
1923 The import of openssl to address the FreeBSD-SA-15:10.openssl
1924 security advisory includes a change which rejects handshakes
1925 with DH parameters below 768 bits. sendmail releases prior
1926 to 8.15.2 (not yet released), defaulted to a 512 bit
1927 DH parameter setting for client connections. To work around
1928 this interoperability, sendmail can be configured to use a
1929 2048 bit DH parameter by:
1931 1. Edit /etc/mail/`hostname`.mc
1932 2. If a setting for confDH_PARAMETERS does not exist or
1933 exists and is set to a string beginning with '5',
1934 replace it with '2'.
1935 3. If a setting for confDH_PARAMETERS exists and is set to
1936 a file path, create a new file with:
1937 openssl dhparam -out /path/to/file 2048
1938 4. Rebuild the .cf file:
1939 cd /etc/mail/; make; make install
1940 5. Restart sendmail:
1941 cd /etc/mail/; make restart
1943 A sendmail patch is coming, at which time this file will be
1947 Generation of legacy formatted entries have been disabled by default
1948 in pwd_mkdb(8), as all base system consumers of the legacy formatted
1949 entries were converted to use the new format by default when the new,
1950 machine independent format have been added and supported since FreeBSD
1953 Please see the pwd_mkdb(8) manual page for further details.
1956 Clang and llvm have been upgraded to 3.6.1 release. Please see the
1957 20141231 entry below for information about prerequisites and upgrading,
1958 if you are not already using 3.5.0 or higher.
1961 TI platform code switched to using vendor DTS files and this update
1962 may break existing systems running on Beaglebone, Beaglebone Black,
1965 - dtb files should be regenerated/reinstalled. Filenames are the
1966 same but content is different now
1967 - GPIO addressing was changed, now each GPIO bank (32 pins per bank)
1968 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
1969 addressing scheme is now pin 25 on /dev/gpioc3.
1970 - Pandaboard: /etc/ttys should be updated, serial console device is
1971 now /dev/ttyu2, not /dev/ttyu0
1974 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
1975 If you need the GNU extension from groff soelim(1), install groff
1976 from package: pkg install groff, or via ports: textproc/groff.
1979 chmod, chflags, chown and chgrp now affect symlinks in -R mode as
1980 defined in symlink(7); previously symlinks were silently ignored.
1983 The const qualifier has been removed from iconv(3) to comply with
1984 POSIX. The ports tree is aware of this from r384038 onwards.
1987 Libraries specified by LIBADD in Makefiles must have a corresponding
1988 DPADD_<lib> variable to ensure correct dependencies. This is now
1989 enforced in src.libnames.mk.
1992 From legacy ata(4) driver was removed support for SATA controllers
1993 supported by more functional drivers ahci(4), siis(4) and mvs(4).
1994 Kernel modules ataahci and ataadaptec were removed completely,
1995 replaced by ahci and mvs modules respectively.
1998 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
1999 the 20141231 entry below for information about prerequisites and
2000 upgrading, if you are not already using 3.5.0 or higher.
2003 The 32-bit PowerPC kernel has been changed to a position-independent
2004 executable. This can only be booted with a version of loader(8)
2005 newer than January 31, 2015, so make sure to update both world and
2006 kernel before rebooting.
2009 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
2010 but before r278950, the RNG was not seeded properly. Immediately
2011 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
2012 ssh keys or openssl keys) that were generated w/ a kernel from that
2013 range. This does not affect programs that directly used /dev/random
2014 or /dev/urandom. All userland uses of arc4random(3) are affected.
2017 The autofs(4) ABI was changed in order to restore binary compatibility
2018 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
2019 with the new kernel.
2022 The powerpc64 kernel has been changed to a position-independent
2023 executable. This can only be booted with a new version of loader(8),
2024 so make sure to update both world and kernel before rebooting.
2027 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
2028 only release, no new features have been added. Please see the 20141231
2029 entry below for information about prerequisites and upgrading, if you
2030 are not already using 3.5.0.
2033 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
2034 taken from the ELF Tool Chain project rather than GNU binutils. They
2035 should be drop-in replacements, with the addition of arm64 support.
2036 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
2037 binutils tools, if necessary. See 20150805 for updated information.
2040 The default Unbound configuration now enables remote control
2041 using a local socket. Users who have already enabled the
2042 local_unbound service should regenerate their configuration
2043 by running "service local_unbound setup" as root.
2046 The GNU texinfo and GNU info pages have been removed.
2047 To be able to view GNU info pages please install texinfo from ports.
2050 Clang, llvm and lldb have been upgraded to 3.5.0 release.
2052 As of this release, a prerequisite for building clang, llvm and lldb is
2053 a C++11 capable compiler and C++11 standard library. This means that to
2054 be able to successfully build the cross-tools stage of buildworld, with
2055 clang as the bootstrap compiler, your system compiler or cross compiler
2056 should either be clang 3.3 or later, or gcc 4.8 or later, and your
2057 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
2060 On any standard FreeBSD 10.x or 11.x installation, where clang and
2061 libc++ are on by default (that is, on x86 or arm), this should work out
2064 On 9.x installations where clang is enabled by default, e.g. on x86 and
2065 powerpc, libc++ will not be enabled by default, so libc++ should be
2066 built (with clang) and installed first. If both clang and libc++ are
2067 missing, build clang first, then use it to build libc++.
2069 On 8.x and earlier installations, upgrade to 9.x first, and then follow
2070 the instructions for 9.x above.
2072 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
2073 default, and do not build clang.
2075 Many embedded systems are resource constrained, and will not be able to
2076 build clang in a reasonable time, or in some cases at all. In those
2077 cases, cross building bootable systems on amd64 is a workaround.
2079 This new version of clang introduces a number of new warnings, of which
2080 the following are most likely to appear:
2084 This warns in two cases, for both C and C++:
2085 * When the code is trying to take the absolute value of an unsigned
2086 quantity, which is effectively a no-op, and almost never what was
2087 intended. The code should be fixed, if at all possible. If you are
2088 sure that the unsigned quantity can be safely cast to signed, without
2089 loss of information or undefined behavior, you can add an explicit
2090 cast, or disable the warning.
2092 * When the code is trying to take an absolute value, but the called
2093 abs() variant is for the wrong type, which can lead to truncation.
2094 If you want to disable the warning instead of fixing the code, please
2095 make sure that truncation will not occur, or it might lead to unwanted
2098 -Wtautological-undefined-compare and
2099 -Wundefined-bool-conversion
2101 These warn when C++ code is trying to compare 'this' against NULL, while
2102 'this' should never be NULL in well-defined C++ code. However, there is
2103 some legacy (pre C++11) code out there, which actively abuses this
2104 feature, which was less strictly defined in previous C++ versions.
2106 Squid and openjdk do this, for example. The warning can be turned off
2107 for C++98 and earlier, but compiling the code in C++11 mode might result
2108 in unexpected behavior; for example, the parts of the program that are
2109 unreachable could be optimized away.
2112 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
2113 kernel sources have been removed. The .h files remain, since some
2114 utilities include them. This will need to be fixed later.
2115 If "mount -t oldnfs ..." is attempted, it will fail.
2116 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
2117 the utilities will report errors.
2120 The handling of LOCAL_LIB_DIRS has been altered to skip addition of
2121 directories to top level SUBDIR variable when their parent
2122 directory is included in LOCAL_DIRS. Users with build systems with
2123 such hierarchies and without SUBDIR entries in the parent
2124 directory Makefiles should add them or add the directories to
2128 faith(4) and faithd(8) have been removed from the base system. Faith
2129 has been obsolete for a very long time.
2132 vt(4), the new console driver, is enabled by default. It brings
2133 support for Unicode and double-width characters, as well as
2134 support for UEFI and integration with the KMS kernel video
2137 You may need to update your console settings in /etc/rc.conf,
2138 most probably the keymap. During boot, /etc/rc.d/syscons will
2139 indicate what you need to do.
2141 vt(4) still has issues and lacks some features compared to
2142 syscons(4). See the wiki for up-to-date information:
2143 https://wiki.freebsd.org/Newcons
2145 If you want to keep using syscons(4), you can do so by adding
2146 the following line to /boot/loader.conf:
2150 pjdfstest has been integrated into kyua as an opt-in test suite.
2151 Please see share/doc/pjdfstest/README for more details on how to
2155 gperf has been removed from the base system for architectures
2156 that use clang. Ports that require gperf will obtain it from the
2160 pjdfstest has been moved from tools/regression/pjdfstest to
2164 At svn r271982, The default linux compat kernel ABI has been adjusted
2165 to 2.6.18 in support of the linux-c6 compat ports infrastructure
2166 update. If you wish to continue using the linux-f10 compat ports,
2167 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
2168 encouraged to update their linux-compat packages to linux-c6 during
2169 their next update cycle.
2172 The ofwfb driver, used to provide a graphics console on PowerPC when
2173 using vt(4), no longer allows mmap() of all physical memory. This
2174 will prevent Xorg on PowerPC with some ATI graphics cards from
2175 initializing properly unless x11-servers/xorg-server is updated to
2179 The xdev targets have been converted to using TARGET and
2180 TARGET_ARCH instead of XDEV and XDEV_ARCH.
2183 The default unbound configuration has been modified to address
2184 issues with reverse lookups on networks that use private
2185 address ranges. If you use the local_unbound service, run
2186 "service local_unbound setup" as root to regenerate your
2187 configuration, then "service local_unbound reload" to load the
2191 The GNU texinfo and GNU info pages are not built and installed
2192 anymore, WITH_INFO knob has been added to allow to built and install
2194 UPDATE: see 20150102 entry on texinfo's removal
2197 The GNU readline library is now an INTERNALLIB - that is, it is
2198 statically linked into consumers (GDB and variants) in the base
2199 system, and the shared library is no longer installed. The
2200 devel/readline port is available for third party software that
2204 The Itanium architecture (ia64) has been removed from the list of
2205 known architectures. This is the first step in the removal of the
2209 Commit r268115 has added NFSv4.1 server support, merged from
2210 projects/nfsv4.1-server. Since this includes changes to the
2211 internal interfaces between the NFS related modules, a full
2212 build of the kernel and modules will be necessary.
2213 __FreeBSD_version has been bumped.
2216 The WITHOUT_VT_SUPPORT kernel config knob has been renamed
2217 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
2218 which differs from the behaviour controlled by this knob.)
2221 Maximal length of the serial number in CTL was increased from 16 to
2222 64 chars, that breaks ABI. All CTL-related tools, such as ctladm
2223 and ctld, need to be rebuilt to work with a new kernel.
2226 The libatf-c and libatf-c++ major versions were downgraded to 0 and
2227 1 respectively to match the upstream numbers. They were out of
2228 sync because, when they were originally added to FreeBSD, the
2229 upstream versions were not respected. These libraries are private
2230 and not yet built by default, so renumbering them should be a
2231 non-issue. However, unclean source trees will yield broken test
2232 programs once the operator executes "make delete-old-libs" after a
2233 "make installworld".
2235 Additionally, the atf-sh binary was made private by moving it into
2236 /usr/libexec/. Already-built shell test programs will keep the
2237 path to the old binary so they will break after "make delete-old"
2240 If you are using WITH_TESTS=yes (not the default), wipe the object
2241 tree and rebuild from scratch to prevent spurious test failures.
2242 This is only needed once: the misnumbered libraries and misplaced
2243 binaries have been added to OptionalObsoleteFiles.inc so they will
2244 be removed during a clean upgrade.
2247 Clang and llvm have been upgraded to 3.4.1 release.
2250 We bogusly installed src.opts.mk in /usr/share/mk. This file should
2251 be removed to avoid issues in the future (and has been added to
2255 /etc/src.conf now affects only builds of the FreeBSD src tree. In the
2256 past, it affected all builds that used the bsd.*.mk files. The old
2257 behavior was a bug, but people may have relied upon it. To get this
2258 behavior back, you can .include /etc/src.conf from /etc/make.conf
2259 (which is still global and isn't changed). This also changes the
2260 behavior of incremental builds inside the tree of individual
2261 directories. Set MAKESYSPATH to ".../share/mk" to do that.
2262 Although this has survived make universe and some upgrade scenarios,
2263 other upgrade scenarios may have broken. At least one form of
2264 temporary breakage was fixed with MAKESYSPATH settings for buildworld
2265 as well... In cases where MAKESYSPATH isn't working with this
2266 setting, you'll need to set it to the full path to your tree.
2268 One side effect of all this cleaning up is that bsd.compiler.mk
2269 is no longer implicitly included by bsd.own.mk. If you wish to
2270 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2274 The lindev device has been removed since /dev/full has been made a
2275 standard device. __FreeBSD_version has been bumped.
2278 The knob WITHOUT_VI was added to the base system, which controls
2279 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2280 in order to reorder files share/termcap and didn't build ex(1) as a
2281 build tool, so building/installing with WITH_VI is highly advised for
2282 build hosts for older releases.
2284 This issue has been fixed in stable/9 and stable/10 in r277022 and
2285 r276991, respectively.
2288 The YES_HESIOD knob has been removed. It has been obsolete for
2289 a decade. Please move to using WITH_HESIOD instead or your builds
2290 will silently lack HESIOD.
2293 The uart(4) driver has been changed with respect to its handling
2294 of the low-level console. Previously the uart(4) driver prevented
2295 any process from changing the baudrate or the CLOCAL and HUPCL
2296 control flags. By removing the restrictions, operators can make
2297 changes to the serial console port without having to reboot.
2298 However, when getty(8) is started on the serial device that is
2299 associated with the low-level console, a misconfigured terminal
2300 line in /etc/ttys will now have a real impact.
2301 Before upgrading the kernel, make sure that /etc/ttys has the
2302 serial console device configured as 3wire without baudrate to
2303 preserve the previous behaviour. E.g:
2304 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
2307 Support for libwrap (TCP wrappers) in rpcbind was disabled by default
2308 to improve performance. To re-enable it, if needed, run rpcbind
2309 with command line option -W.
2312 Switched back to the GPL dtc compiler due to updates in the upstream
2313 dts files not being supported by the BSDL dtc compiler. You will need
2314 to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2315 may result while building dtb files during a kernel build if you fail
2316 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
2319 Clang and llvm have been upgraded to 3.4 release.
2322 The nve(4) driver has been removed. Please use the nfe(4) driver
2323 for NVIDIA nForce MCP Ethernet adapters instead.
2326 An ABI incompatibility crept into the libc++ 3.4 import in r261283.
2327 This could cause certain C++ applications using shared libraries built
2328 against the previous version of libc++ to crash. The incompatibility
2329 has now been fixed, but any C++ applications or shared libraries built
2330 between r261283 and r261801 should be recompiled.
2333 OpenSSH will now ignore errors caused by kernel lacking of Capsicum
2334 capability mode support. Please note that enabling the feature in
2335 kernel is still highly recommended.
2338 OpenSSH is now built with sandbox support, and will use sandbox as
2339 the default privilege separation method. This requires Capsicum
2340 capability mode support in kernel.
2343 The libelf and libdwarf libraries have been updated to newer
2344 versions from upstream. Shared library version numbers for
2345 these two libraries were bumped. Any ports or binaries
2346 requiring these two libraries should be recompiled.
2347 __FreeBSD_version is bumped to 1100006.
2350 If a Makefile in a tests/ directory was auto-generating a Kyuafile
2351 instead of providing an explicit one, this would prevent such
2352 Makefile from providing its own Kyuafile in the future during
2353 NO_CLEAN builds. This has been fixed in the Makefiles but manual
2354 intervention is needed to clean an objdir if you use NO_CLEAN:
2355 # find /usr/obj -name Kyuafile | xargs rm -f
2358 The behavior of gss_pseudo_random() for the krb5 mechanism
2359 has changed, for applications requesting a longer random string
2360 than produced by the underlying enctype's pseudo-random() function.
2361 In particular, the random string produced from a session key of
2362 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
2363 be different at the 17th octet and later, after this change.
2364 The counter used in the PRF+ construction is now encoded as a
2365 big-endian integer in accordance with RFC 4402.
2366 __FreeBSD_version is bumped to 1100004.
2369 The WITHOUT_ATF build knob has been removed and its functionality
2370 has been subsumed into the more generic WITHOUT_TESTS. If you were
2371 using the former to disable the build of the ATF libraries, you
2372 should change your settings to use the latter.
2375 The default version of mtree is nmtree which is obtained from
2376 NetBSD. The output is generally the same, but may vary
2377 slightly. If you found you need identical output adding
2378 "-F freebsd9" to the command line should do the trick. For the
2379 time being, the old mtree is available as fmtree.
2382 libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
2383 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
2384 1.1.4_8 and verify bsdyml not linked in, before running "make
2386 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
2388 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
2391 The stable/10 branch has been created in subversion from head
2398 Sometimes, obscure build problems are the result of environment
2399 poisoning. This can happen because the make utility reads its
2400 environment when searching for values for global variables. To run
2401 your build attempts in an "environmental clean room", prefix all make
2402 commands with 'env -i '. See the env(1) manual page for more details.
2403 Occasionally a build failure will occur with "make -j" due to a race
2404 condition. If this happens try building again without -j, and please
2405 report a bug if it happens consistently.
2407 When upgrading from one major version to another it is generally best to
2408 upgrade to the latest code in the currently installed branch first, then
2409 do an upgrade to the new branch. This is the best-tested upgrade path,
2410 and has the highest probability of being successful. Please try this
2411 approach if you encounter problems with a major version upgrade. Since
2412 the stable 4.x branch point, one has generally been able to upgrade from
2413 anywhere in the most recent stable branch to head / current (or even the
2414 last couple of stable branches). See the top of this file when there's
2417 The update process will emit an error on an attempt to perform a build
2418 or install from a FreeBSD version below the earliest supported version.
2419 When updating from an older version the update should be performed one
2420 major release at a time, including running `make delete-old` at each
2423 When upgrading a live system, having a root shell around before
2424 installing anything can help undo problems. Not having a root shell
2425 around can lead to problems if pam has changed too much from your
2426 starting point to allow continued authentication after the upgrade.
2428 This file should be read as a log of events. When a later event changes
2429 information of a prior event, the prior event should not be deleted.
2430 Instead, a pointer to the entry with the new information should be
2431 placed in the old entry. Readers of this file should also sanity check
2432 older entries before relying on them blindly. Authors of new entries
2433 should write them with this in mind.
2437 When upgrading the boot ZFS pool to a new version, always follow
2440 1.) recompile and reinstall the ZFS boot loader and boot block
2441 (this is part of "make buildworld" and "make installworld")
2443 2.) update the ZFS boot block on your boot drive
2445 The following example updates the ZFS boot block on the
2446 freebsd-boot partition of a GPT partitioned drive ada0:
2447 "gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2448 The value $N will typically be 1 (if booting from BIOS) or 2 (if
2451 Non-boot pools do not need these updates.
2455 If you are updating from a prior version of FreeBSD (even one just
2456 a few days old), you should follow this procedure. It is the most
2457 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
2459 make kernel-toolchain
2460 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
2461 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
2463 To test a kernel once
2464 ---------------------
2465 If you just want to boot a kernel once (because you are not sure
2466 if it works, or if you want to boot a known bad kernel to provide
2467 debugging information) run
2468 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
2469 nextboot -k testkernel
2471 To rebuild everything and install it on the current system.
2472 -----------------------------------------------------------
2473 # Note: sometimes if you are running current you gotta do more than
2474 # is listed here if you are upgrading from a really old current.
2476 <make sure you have good level 0 dumps>
2478 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2479 make installkernel KERNCONF=YOUR_KERNEL_HERE
2481 <reboot in single user> [3]
2488 To cross-install current onto a separate partition
2489 --------------------------------------------------
2490 # In this approach we use a separate partition to hold
2491 # current's root, 'usr', and 'var' directories. A partition
2492 # holding "/", "/usr" and "/var" should be about 2GB in
2495 <make sure you have good level 0 dumps>
2498 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2499 <maybe newfs current's root partition>
2500 <mount current's root partition on directory ${CURRENT_ROOT}>
2501 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
2502 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
2503 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
2504 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
2505 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
2506 <reboot into current>
2507 <do a "native" rebuild/install as described in the previous section>
2508 <maybe install compatibility libraries from ports/misc/compat*>
2512 To upgrade in-place from stable to current
2513 ----------------------------------------------
2514 <make sure you have good level 0 dumps>
2516 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
2517 make installkernel KERNCONF=YOUR_KERNEL_HERE
2519 <reboot in single user> [3]
2526 Make sure that you've read the UPDATING file to understand the
2527 tweaks to various things you need. At this point in the life
2528 cycle of current, things change often and you are on your own
2529 to cope. The defaults can also change, so please read ALL of
2530 the UPDATING entries.
2532 Also, if you are tracking -current, you must be subscribed to
2533 freebsd-current@freebsd.org. Make sure that before you update
2534 your sources that you have read and understood all the recent
2535 messages there. If in doubt, please track -stable which has
2536 much fewer pitfalls.
2538 [1] If you have third party modules, such as vmware, you should disable
2539 them at this point so they don't crash your system on
2540 reboot. Alternatively, you should rebuild all the modules you have in
2541 your system and install them as well. If you are running -current, you
2542 should seriously consider placing all sources to all the modules for
2543 your system (or symlinks to them) in /usr/local/sys/modules so this
2544 happens automatically. If all your modules come from ports, then adding
2545 the port origin directories to PORTS_MODULES instead is also automatic
2547 PORTS_MODULES+=x11/nvidia-driver
2549 [3] From the bootblocks, boot -s, and then do
2553 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed
2554 cd src # full path to source
2555 adjkerntz -i # if CMOS is wall time
2556 Also, when doing a major release upgrade, it is required that you boot
2557 into single user mode to do the installworld.
2559 [4] Note: This step is non-optional. Failure to do this step
2560 can result in a significant reduction in the functionality of the
2561 system. Attempting to do it by hand is not recommended and those
2562 that pursue this avenue should read this file carefully, as well
2563 as the archives of freebsd-current and freebsd-hackers mailing lists
2564 for potential gotchas. The -U option is also useful to consider.
2565 See mergemaster(8) for more information.
2567 [5] Usually this step is a no-op. However, from time to time
2568 you may need to do this if you get unknown user in the following
2569 step. It never hurts to do it all the time. You may need to
2570 install a new mergemaster (cd src/usr.sbin/mergemaster && make
2571 install) after the buildworld before this step if you last updated
2572 from current before 20130425 or from -stable before 20130430.
2574 [6] This only deletes old files and directories. Old libraries
2575 can be deleted by "make delete-old-libs", but you have to make
2576 sure that no program is using those libraries anymore.
2578 [8] The new kernel must be able to run existing binaries used by an
2579 installworld. When upgrading across major versions, the new kernel's
2580 configuration must include the correct COMPAT_FREEBSD<n> option for
2581 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure
2582 to do so may leave you with a system that is hard to boot to recover. A
2583 GENERIC kernel will include suitable compatibility options to run
2584 binaries from older branches. Note that the ability to run binaries
2585 from unsupported branches is not guaranteed.
2587 Make sure that you merge any new devices from GENERIC since the
2588 last time you updated your kernel config file. Options also
2589 change over time, so you may need to adjust your custom kernels
2592 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2593 "?=" instead of the "=" assignment operator, so that buildworld can
2594 override the CPUTYPE if it needs to.
2596 MAKEOBJDIRPREFIX must be defined in an environment variable, and
2597 not on the command line, or in /etc/make.conf. buildworld will
2598 warn if it is improperly defined.
2601 This file contains a list, in reverse chronological order, of major
2602 breakages in tracking -current. It is not guaranteed to be a complete
2603 list of such breakages, and only contains entries since September 23, 2011.
2604 If you need to see UPDATING entries from before that date, you will need
2605 to fetch an UPDATING file from an older FreeBSD release.
