146 Various LinuxKPI functionality was added which conflicts with DRM.
147 Please update your drm-kmod port to after the __FreeBSD_verison 1300139
151 The stable/13 branch has been created from main.
154 PC Card attachments for all devices have been removed. In the case of
155 wi and cmx, the entire drivers were removed because they were only
156 PC Card devices. FreeBSD_version 1300134 should be used for this
157 since it was bumped so recently.
160 Transport-independent parts of HID support have been split off the USB
161 code in to separate subsystem. Kernel configs which include one of
162 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
163 be updated with adding of "device hid" line.
166 ncurses installation has been modified to only keep the widechar
167 enabled version. Incremental build is broken for that change, so it
168 requires a clean build.
171 The FreeBSD project has migrated from Subversion to Git. Temporary
172 instructions can be found at
173 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
174 and other documents in that repo.
177 The services database has been updated to cover more of the basic
178 services expected in a modern system. The database is big enough
179 that it will cause issues in mergemaster in Releases previous to
180 12.2 and 11.3, or in very old current systems from before r358154.
183 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
184 may be installed from ports or packages.
187 ping6 has been merged into ping. It can now be called as "ping -6".
188 See ping(8) for details.
191 Default value of net.add_addr_allfibs has been changed to 0.
192 If you have multi-fib configuration and rely on existence of all
193 interface routes in every fib, you need to set the above sysctl to 1.
195 The internal pre-processor in the calendar(1) program has been
196 extended to support more C pre-processor commands (e.g. #ifdef, #else,
197 and #undef) and to detect unbalanced conditional statements.
198 Error messages have been extended to include the filename and line
199 number if processing stops to help fixing malformed data files.
202 All the data files for the calendar(1) program, except calendar.freebsd,
203 have been moved to the deskutils/calendar-data port, much like the
204 jewish calendar entries were moved to deskutils/hebcal years ago. After
205 make delete-old-files, you need to install it to retain full
206 functionality. calendar(1) will issue a reminder for files it can't
210 LINT files are no longer generated. We now include the relevant NOTES
211 files. Note: This may cause conflicts with updating in some cases.
212 find sys -name LINT\* -delete
213 is suggested across this commit to remove the generated LINT files.
215 If you have tried to update with generated files there, the svn
216 command you want to un-auger the tree is
219 and then do the above find from the top level. Substitute 'amd64'
220 above with where the error message indicates a conflict.
223 OpenZFS support has been integrated. Do not upgrade root pools until
224 the loader is updated to support zstd. Furthermore, we caution against
225 'zpool upgrade' for the next few weeks. The change should be transparent
226 unless you want to use new features.
228 Not all "NO_CLEAN" build scenarios work across these changes. Many
229 scenarios have been tested and fixed, but rebuilding kernels without
230 rebuilding world may fail.
232 The ZFS cache file has moved from /boot to /etc to match the OpenZFS
233 upstream default. A fallback to /boot has been added for mountroot.
235 Pool auto import behavior at boot has been moved from the kernel module
236 to an explicit "zpool import -a" in one of the rc scripts enabled by
237 zfs_enable=YES. This means your non-root zpools won't auto import until
238 you upgrade your /etc/rc.d files.
241 The resume code now notifies devd with the 'kernel' system
242 rather than the old 'kern' subsystem to be consistent with
243 other use. The old notification will be created as well, but
244 will be removed prior to FreeBSD 14.0.
247 r362275 changed the internal API between the kernel RPC and the
248 NFS modules. As such, all the modules must be recompiled from
252 r364330 modified the internal API used between the NFS modules.
253 As such, all the NFS modules must be re-compiled from sources.
256 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
257 been upgraded to 11.0.0. Please see the 20141231 entry below for
258 information about prerequisites and upgrading, if you are not already
259 using clang 3.5.0 or higher.
262 r364092 modified the internal ABI used between the kernel NFS
263 modules. As such, all of these modules need to be rebuilt
264 from sources, so a version bump was done.
267 Makefile.inc has been updated to work around the issue documented in
268 20200729. It was a case where the optimization of using symbolic links
269 to point to binaries created a situation where we'd run new binaries
270 with old libraries starting midway through the installworld process.
273 r363679 has redefined some undefined behavior in regcomp(3); notably,
274 extraneous escapes of most ordinary characters will no longer be
275 accepted. An exp-run has identified all of the problems with this in
276 ports, but other non-ports software may need extra escapes removed to
277 continue to function.
279 Because of this change, installworld may encounter the following error
280 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
281 you do not halt installworld. Instead, let it run to completion (whether
282 successful or not) and run installworld once more.
285 A new implementation of bc and dc has been imported in r362681. This
286 implementation corrects non-conformant behavior of the previous bc
287 and adds GNU bc compatible options. It offers a number of extensions,
288 is much faster on large values, and has support for message catalogs
289 (a number of languages are already supported, contributions of further
290 languages welcome). The option WITHOUT_GH_BC can be used to build the
291 world with the previous versions of bc and dc.
294 r362639 changed the internal API used between the NFS kernel modules.
295 As such, they all need to be rebuilt from sources.
298 r362158 changed the arguments for VFS_CHECKEXP(). As such, any
299 out of tree file systems need to be modified and rebuilt.
300 Also, any file systems that are modules must be rebuilt.
303 read(2) of a directory fd is now rejected by default. root may
304 re-enable it for system root only on non-ZFS filesystems with the
305 security.bsd.allow_read_dir sysctl(8) MIB if
306 security.bsd.suser_enabled=1.
308 It may be advised to setup aliases for grep to default to `-d skip` if
309 commonly non-recursively grepping a list that includes directories and
310 the potential for the resulting stderr output is not tolerable. Example
311 aliases are now installed, commented out, in /root/.cshrc and
315 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
316 been upgraded to 10.0.1. Please see the 20141231 entry below for
317 information about prerequisites and upgrading, if you are not already
318 using clang 3.5.0 or higher.
321 Support for obsolete compilers has been removed from the build system.
322 Clang 6 and GCC 6.4 are the minimum supported versions.
325 closefrom(2) has been moved under COMPAT12, and replaced in libc with a
326 stub that calls close_range(2). If using a custom kernel configuration,
327 you may want to ensure that the COMPAT_FREEBSD12 option is included, as
328 a slightly older -CURRENT userland and older FreeBSD userlands may not
329 be functional without closefrom(2).
332 Upstream DTS from Linux 5.6 was merged and they now have the SID
333 and THS (Secure ID controller and THermal Sensor) node present.
334 The DTB overlays have now been removed from the tree for the H3/H5 and
335 A64 SoCs and the aw_sid and aw_thermal driver have been updated to
336 deal with upstream DTS. If you are using those overlays you need to
337 remove them from loader.conf and update the DTBs on the FAT partition.
340 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
341 been upgraded to 10.0.0. Please see the 20141231 entry below for
342 information about prerequisites and upgrading, if you are not already
343 using clang 3.5.0 or higher.
346 The amd(8) automount daemon has been removed from the source tree.
347 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
348 amd is still available in the sysutils/am-utils port.
351 Removed brooktree driver (bktr.4) from the tree.
354 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
355 compiler in usr.bin/dtc is used on all architectures which use dtc, and
356 the GPL dtc is available (if needed) from the sysutils/dtc port.
359 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
360 is used by all supported CPU architectures.
363 GCC 4.2.1 has been removed from the tree. The WITH_GCC,
364 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
365 Users who wish to build FreeBSD with GCC must use the external toolchain
369 ncurses has been updated to a newer version (6.2-20200215). Given the ABI
370 has changed, users will have to rebuild all the ports that are linked to
374 The size of struct vnet and the magic cookie have changed.
375 Users need to recompile libkvm and all modules using VIMAGE
376 together with their new kernel.
379 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
380 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
381 your Makefiles and scripts to define MK_<var>=no instead as required.
383 One exception to this is that program or library Makefiles should
384 define MAN to empty rather than setting MK_MAN=no.
387 Clang/LLVM is now the default compiler and LLD the default
391 make universe no longer uses GCC 4.2.1 on any architectures.
392 Architectures not supported by in-tree Clang/LLVM require an
393 external toolchain package.
396 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
397 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
398 options default to off for all supported CPU architectures. As a
399 short-term transition aid they may be enabled via WITH_* options.
400 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
403 Support for armv5 has been disconnected and is being removed. The
404 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
405 You must now use a MACHINE_ARCH of armv6 or armv7. The default
406 MACHINE_ARCH for MACHINE=arm is now armv7.
409 Clang/LLVM is now the default compiler for all powerpc architectures.
410 LLD is now the default linker for powerpc64. The change for powerpc64
411 also includes a change to the ELFv2 ABI, incompatible with the existing
415 Kernel-loadable random(4) modules are no longer unloadable.
418 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
419 been upgraded to 9.0.1. Please see the 20141231 entry below for
420 information about prerequisites and upgrading, if you are not already
421 using clang 3.5.0 or higher.
424 r355677 has modified the internal interface used between the
425 NFS modules in the kernel. As such, they must all be upgraded
426 simultaneously. I will do a version bump for this.
429 The root certificates of the Mozilla CA Certificate Store have been
430 imported into the base system and can be managed with the certctl(8)
431 utility. If you have installed the security/ca_root_nss port or package
432 with the ETCSYMLINK option (the default), be advised that there may be
433 differences between those included in the port and those included in
434 base due to differences in nss branch used as well as general update
435 frequency. Note also that certctl(8) cannot manage certs in the
436 format used by the security/ca_root_nss port.
439 The amd(8) automount daemon has been disabled by default, and will be
440 removed in the future. As of FreeBSD 10.1 the autofs(5) is available
444 The nctgpio and wbwd drivers have been moved to the superio bus.
445 If you have one of these drivers in a kernel configuration, then
446 you should add device superio to it. If you use one of these drivers
447 as a module and you compile a custom set of modules, then you should
448 add superio to the set.
451 KPIs for network drivers to access interface addresses have changed.
452 Users need to recompile NIC driver modules together with kernel.
455 The net.link.tap.user_open sysctl no longer prevents user opening of
456 already created /dev/tapNN devices. Access is still controlled by
457 node permissions, just like tun devices. The net.link.tap.user_open
458 sysctl is now used only to allow users to perform devfs cloning of
459 tap devices, and the subsequent open may not succeed if the user is not
460 in the appropriate group. This sysctl may be deprecated/removed
461 completely in the future.
464 mips, powerpc, and sparc64 are no longer built as part of
465 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
466 not defined, mips, powerpc, and sparc64 builds will look for
467 the xtoolchain binaries and if installed use them for universe
468 builds. As llvm 9.0 becomes vetted for these architectures, they
469 will be removed from the list.
472 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
473 been upgraded to 9.0.0. Please see the 20141231 entry below for
474 information about prerequisites and upgrading, if you are not already
475 using clang 3.5.0 or higher.
478 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
479 GENERIC. They are available as modules and can be loaded by adding
480 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
481 hptnr_load="YES", or hptrr_load="YES", respectively.
484 ntpd no longer by default locks its pages in memory, allowing them
485 to be paged out by the kernel. Use rlimit memlock to restore
486 historic BSD behaviour. For example, add "rlimit memlock 32"
487 to ntp.conf to lock up to 32 MB of ntpd address space in memory.
490 Several of ping6's options have been renamed for better consistency
491 with ping. If you use any of -ARWXaghmrtwx, you must update your
492 scripts. See ping6(8) for details.
495 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
496 and the "-o sync_unmount" and "-o init_backgrounded" mount options have
497 been removed from mount_fusefs(8). You can safely remove them from
498 your scripts, because they had no effect.
500 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
501 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
502 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
503 sysctls have been removed. If you felt the need to set any of them to
504 a non-default value, please tell asomers@FreeBSD.org why.
507 Default permissions on the /var/account/acct file (and copies of it
508 rotated by periodic daily scripts) are changed from 0644 to 0640
509 because the file contains sensitive information that should not be
510 world-readable. If the /var/account directory must be created by
511 rc.d/accounting, the mode used is now 0750. Admins who use the
512 accounting feature are encouraged to change the mode of an existing
513 /var/account directory to 0750 or 0700.
516 Entropy collection and the /dev/random device are no longer optional
517 components. The "device random" option has been removed.
518 Implementations of distilling algorithms can still be made loadable
519 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
522 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
523 been upgraded to 8.0.1. Please see the 20141231 entry below for
524 information about prerequisites and upgrading, if you are not already
525 using clang 3.5.0 or higher.
528 A fix was applied to i386 kernel modules to avoid panics with
529 dpcpu or vnet. Users need to recompile i386 kernel modules
530 having pcpu or vnet sections or they will refuse to load.
533 User-wired pages now have their own counter,
534 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
535 to vm.max_user_wired and changed from an unsigned int to an unsigned
536 long. bhyve VMs wired with the -S are now subject to the user
537 wiring limit; the vm.max_user_wired sysctl may need to be tuned to
538 avoid running into the limit.
541 The IPSEC option has been removed from GENERIC. Users requiring
542 ipsec(4) must now load the ipsec(4) kernel module.
545 The tap(4) driver has been folded into tun(4), and the module has been
546 renamed to tuntap. You should update any kld_list="if_tap" or
547 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
548 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
549 module instead, and "device tap" or "device tun" entries in kernel
550 config files to select the tuntap device instead.
553 The following knobs have been added related to tradeoffs between
554 safe use of the random device and availability in the absence of
557 kern.random.initial_seeding.bypass_before_seeding: tunable; set
558 non-zero to bypass the random device prior to seeding, or zero to
559 block random requests until the random device is initially seeded.
560 For now, set to 1 (unsafe) by default to restore pre-r346250 boot
561 availability properties.
563 kern.random.initial_seeding.read_random_bypassed_before_seeding:
564 read-only diagnostic sysctl that is set when bypass is enabled and
565 read_random(9) is bypassed, to enable programmatic handling of this
566 initial condition, if desired.
568 kern.random.initial_seeding.arc4random_bypassed_before_seeding:
569 Similar to the above, but for for arc4random(9) initial seeding.
571 kern.random.initial_seeding.disable_bypass_warnings: tunable; set
572 non-zero to disable warnings in dmesg when the same conditions are
573 met as for the diagnostic sysctls above. Defaults to zero, i.e.,
574 produce warnings in dmesg when the conditions are met.
577 The loadable random module KPI has changed; the random_infra_init()
578 routine now requires a 3rd function pointer for a bool (*)(void)
579 method that returns true if the random device is seeded (and
580 therefore unblocked).
583 r345895 reverts r320698. This implies that an nfsuserd(8) daemon
584 built from head sources between r320757 (July 6, 2017) and
585 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
586 is added to the command line.
587 nfsuserd daemons built from head sources that are post-r338192 are
588 not affected and should continue to work.
591 The fuse(4) module has been renamed to fusefs(4) for consistency with
592 other filesystems. You should update any kld_load="fuse" entries in
593 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
594 "options FUSE" entries in kernel config files.
597 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
598 8.0.0. Please see the 20141231 entry below for information about
599 prerequisites and upgrading, if you are not already using clang 3.5.0
603 geom_uzip(4) depends on the new module xz. If geom_uzip is statically
604 compiled into your custom kernel, add 'device xz' statement to the
608 drm and drm2 have been removed from the tree. Please see
609 https://wiki.freebsd.org/Graphics for the latest information on
610 migrating to the drm ports.
613 Iflib is no longer unconditionally compiled into the kernel. Drivers
614 using iflib and statically compiled into the kernel, now require
615 the 'device iflib' config option. For the same drivers loaded as
616 modules on kernels not having 'device iflib', the iflib.ko module
617 is loaded automatically.
620 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
621 options no longer exist since r343219 and r343427 respectively;
622 nothing uses them, so they should be just removed from custom
626 r342635 changes the way efibootmgr(8) works by requiring users to add
627 the -b (bootnum) parameter for commands where the bootnum was previously
628 specified with each option. For example 'efibootmgr -B 0001' is now
629 'efibootmgr -B -b 0001'.
632 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
633 in the same as it is applied to NFSv2 and 3. This implies that NFSv4
634 servers that have vfs.nfsd.nfs_privport set will only allow mounts
635 from clients using a reserved port#. Since both the FreeBSD and Linux
636 NFSv4 clients use reserved port#s by default, this should not affect
640 The XLP config has been removed. We can't support 64-bit atomics in this
641 kernel because it is running in 32-bit mode. XLP users must transition
642 to running a 64-bit kernel (XLP64 or XLPN32).
644 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
645 the preferred emulator today and we don't need two different ones.
647 The old sibyte / swarm / Broadcom BCM1250 support has been
648 removed from the mips port.
651 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
652 7.0.1. Please see the 20141231 entry below for information about
653 prerequisites and upgrading, if you are not already using clang 3.5.0
657 Remove the timed and netdate programs from the base tree. Setting
658 the time with these daemons has been obsolete for over a decade.
661 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
662 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
663 it produces broken binaries when ifuncs are in use. Users needing
664 GNU ld should install the binutils port or package.
667 The BSD crtbegin and crtend code has been enabled by default. It has
668 had extensive testing on amd64, arm64, and i386. It can be disabled
669 by building a world with -DWITHOUT_BSD_CRTBEGIN.
672 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
673 has been converted to a port (misc/ctm) and will be removed from
674 FreeBSD-13. It is available as a package (ctm) for all supported
678 The default newsyslog.conf(5) file has been changed to only include
679 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
680 the filenames end in '.conf' and do not begin with a '.'.
682 You should check the configuration files in these two directories match
683 this naming convention. You can verify which configuration files are
684 being included using the command:
688 Ports for the DRM modules have been simplified. Now, amd64 users should
689 just install the drm-kmod port. All others should install
692 Graphics hardware that's newer than about 2010 usually works with
693 drm-kmod. For hardware older than 2013, however, some users will need
694 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
695 than 2008 usually only works in drm-legacy-kmod. The graphics team can
696 only commit to hardware made since 2013 due to the complexity of the
697 market and difficulty to test all the older cards effectively. If you
698 have hardware supported by drm-kmod, you are strongly encouraged to use
699 that as you will get better support.
701 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
702 elsewhere, the drm and drm2 modules will be eliminated from the src base
703 soon (with a limited exception for arm). Please update to the package
704 asap and report any issues to x11@freebsd.org.
706 Generally, anybody using the drm*-kmod packages should add
707 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
708 cross-threading surprises, especially with automatic driver
709 loading from X11 startup. These will become the defaults in 13-current
713 The ixlv(4) driver has been renamed to iavf(4). As a consequence,
714 custom kernel and module loading configuration files must be updated
715 accordingly. Moreover, interfaces previous presented as ixlvN to the
716 system are now exposed as iavfN and network configuration files must
717 be adjusted as necessary.
720 OpenSSL has been updated to version 1.1.1. This update included
721 additional various API changes throughout the base system. It is
722 important to rebuild third-party software after upgrading. The value
723 of __FreeBSD_version has been bumped accordingly.
726 The legacy DRM modules and drivers have now been added to the loader's
727 module blacklist, in favor of loading them with kld_list in rc.conf(5).
728 The module blacklist may be overridden with the loader.conf(5)
729 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
733 The cam(4) based nda(4) driver will be used over nvd(4) by default on
734 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
735 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
736 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
740 Reproducible build mode is now on by default, in preparation for
741 FreeBSD 12.0. This eliminates build metadata such as the user,
742 host, and time from the kernel (and uname), unless the working tree
743 corresponds to a modified checkout from a version control system.
744 The previous behavior can be obtained by setting the /etc/src.conf
745 knob WITHOUT_REPRODUCIBLE_BUILD.
748 The Yarrow CSPRNG has been removed from the kernel as it has not been
749 supported by its designers since at least 2003. Fortuna has been the
750 default since FreeBSD-11.
753 devctl freeze/thaw have gone into the tree, the rc scripts have been
754 updated to use them and devmatch has been changed. You should update
755 kernel, userland and rc scripts all at the same time.
758 The default interpreter has been switched from 4th to Lua.
759 LOADER_DEFAULT_INTERP, documented in build(7), will override the default
760 interpreter. If you have custom FORTH code you will need to set
761 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
762 src.conf for the build. This will create default hard links between
763 loader and loader_4th instead of loader and loader_lua, the new default.
764 If you are using UEFI it will create the proper hard link to loader.efi.
766 bhyve uses userboot.so. It remains 4th-only until some issues are solved
767 regarding coexisting with multiple versions of FreeBSD are resolved.
770 ls(1) now respects the COLORTERM environment variable used in other
771 systems and software to indicate that a colored terminal is both
772 supported and desired. If ls(1) is suddenly emitting colors, they may
773 be disabled again by either removing the unwanted COLORTERM from your
774 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
775 may not be observed in a future release.
778 The default pager for most commands has been changed to "less". To
779 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
783 The jedec_ts(4) driver has been removed. A superset of its functionality
784 is available in the jedec_dimm(4) driver, and the manpage for that
785 driver includes migration instructions. If you have "device jedec_ts"
786 in your kernel configuration file, it must be removed.
789 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
790 This should have no effect if the kernel is booted via BIOS/legacy boot.
791 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
792 has a buggy firmware that prevents a successful boot due to use of
796 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
797 support has been removed from the tree. These ports were
798 obsolete and/or known to be broken for many years.
801 loader.efi has been augmented to participate more fully in the
802 UEFI boot manager protocol. loader.efi will now look at the
803 BootXXXX environment variable to determine if a specific kernel
804 or root partition was specified. XXXX is derived from BootCurrent.
805 efibootmgr(8) manages these standard UEFI variables.
808 zfsloader's functionality has now been folded into loader.
809 zfsloader is no longer necessary once you've updated your
810 boot blocks. For a transition period, we will install a
811 hardlink for zfsloader to loader to allow a smooth transition
812 until the boot blocks can be updated (hard link because old
813 zfs boot blocks don't understand symlinks).
816 ARM64 now have efifb support, if you want to have serial console
817 on your arm64 board when an screen is connected and the bootloader
818 setup a frame buffer for us to use, just add :
822 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
823 an screen connected as the firmware will setup a frame buffer are that
824 u-boot will expose as an EFI frame buffer.
827 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
828 or take steps to update /etc/passwd before doing installworld on
829 existing systems. Do not skip the "mergemaster -Fp" step before
830 installworld, as described in the update procedures near the bottom
831 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
832 if the new mac_ntpd(4) policy is available, unless ntpd_flags or
833 the ntp config file contain options that change file/dir locations.
834 When such options (e.g., "statsdir" or "crypto") are used, ntpd can
835 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
836 taking steps to ensure that all required files/dirs are accessible
840 Big endian arm support has been removed.
843 The static environment setup in kernel configs is no longer mutually
844 exclusive with the loader(8) environment by default. In order to
845 restore the previous default behavior of disabling the loader(8)
846 environment if a static environment is present, you must specify
847 loader_env.disabled=1 in the static environment.
850 The ABI of syscalls used by management tools like sockstat and
851 netstat has been broken to allow 32-bit binaries to work on
852 64-bit kernels without modification. These programs will need
853 to match the kernel in order to function. External programs may
854 require minor modifications to accommodate a change of type in
855 structures from pointers to 64-bit virtual addresses.
858 On i386 and amd64 atomics are now inlined. Out of tree modules using
859 atomics will need to be rebuilt.
862 The '%I' format in the kern.corefile sysctl limits the number of
863 core files that a process can generate to the number stored in the
864 debug.ncores sysctl. The '%I' format is replaced by the single digit
865 index. Previously, if all indexes were taken the kernel would overwrite
866 only a core file with the highest index in a filename.
867 Currently the system will create a new core file if there is a free
868 index or if all slots are taken it will overwrite the oldest one.
871 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
872 6.0.1. Please see the 20141231 entry below for information about
873 prerequisites and upgrading, if you are not already using clang 3.5.0
877 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
878 needed to be changed to work with it. This change was made with r335763
879 and requires a mergemaster / etcupdate / etc to update the installed
883 r334930 changed the interface between the NFS modules, so they all
884 need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
887 As of r334391 lld is the default amd64 system linker; it is installed
888 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
892 The kernel / userland interface for devinfo changed, so you'll
893 need a new kernel and userland as a pair for it to work (rebuilding
894 lib/libdevinfo is all that's required). devinfo and devmatch will
895 not work, but everything else will when there's a mismatch.
898 The on-disk format for hwpmc callchain records has changed to include
899 threadid corresponding to a given record. This changes the field offsets
900 and thus requires that libpmcstat be rebuilt before using a kernel
904 The vxge(4) driver has been removed. This driver was introduced into
905 HEAD one week before the Exar left the Ethernet market and is not
906 known to be used. If you have device vxge in your kernel config file
910 The amd64 kernel now requires a ld that supports ifunc to produce a
911 working kernel, either lld or a newer binutils. lld is built by default
912 on amd64, and the 'buildkernel' target uses it automatically. However,
913 it is not the default linker, so building the kernel the traditional
914 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
915 binutils port/package). lld will soon be default, and this requirement
918 NOTE: As of r334391 lld is the default system linker on amd64, and no
919 workaround is necessary.
922 The nxge(4) driver has been removed. This driver was for PCI-X 10g
923 cards made by s2io/Neterion. The company was acquired by Exar and
924 no longer sells or supports Ethernet products. If you have device
925 nxge in your kernel config file it must be removed.
928 The tz database (tzdb) has been updated to 2018e. This version more
929 correctly models time stamps in time zones with negative DST such as
930 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
931 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
932 time zone abbreviations and the tm_isdst flag.
935 The ixgb(4) driver has been removed. This driver was for an early and
936 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
937 quickly shifted to the long lived ixgbe family. If you have device
938 ixgb in your kernel config file it must be removed.
941 The lmc(4) driver has been removed. This was a WAN interface
942 card that was already reportedly rare in 2003, and had an ambiguous
943 license. If you have device lmc in your kernel config file it must
947 Support for Arcnet networks has been removed. If you have device
948 arcnet or device cm in your kernel config file they must be
952 Support for FDDI networks has been removed. If you have device
953 fddi or device fpa in your kernel config file they must be
957 In addition to supporting RFC 3164 formatted messages, the
958 syslogd(8) service is now capable of parsing RFC 5424 formatted
959 log messages. The main benefit of using RFC 5424 is that clients
960 may now send log messages with timestamps containing year numbers,
961 microseconds and time zone offsets.
963 Similarly, the syslog(3) C library function has been altered to
964 send RFC 5424 formatted messages to the local system logging
965 daemon. On systems using syslogd(8), this change should have no
966 negative impact, as long as syslogd(8) and the C library are
967 updated at the same time. On systems using a different system
968 logging daemon, it may be necessary to make configuration
969 adjustments, depending on the software used.
971 When using syslog-ng, add the 'syslog-protocol' flag to local
972 input sources to enable parsing of RFC 5424 formatted messages:
975 unix-dgram("/var/run/log" flags(syslog-protocol));
978 When using rsyslog, disable the 'SysSock.UseSpecialParser' option
979 of the 'imuxsock' module to let messages be processed by the
980 regular RFC 3164/5424 parsing pipeline:
982 module(load="imuxsock" SysSock.UseSpecialParser="off")
984 Do note that these changes only affect communication between local
985 applications and syslogd(8). The format that syslogd(8) uses to
986 store messages on disk or forward messages to other systems
987 remains unchanged. syslogd(8) still uses RFC 3164 for these
988 purposes. Options to customize this behaviour will be added in the
989 future. Utilities that process log files stored in /var/log are
990 thus expected to continue to function as before.
992 __FreeBSD_version has been incremented to 1200061 to denote this
996 Support for token ring networks has been removed. If you
997 have "device token" in your kernel config you should remove
998 it. No device drivers supported token ring.
1001 makefs was modified to be able to tag ISO9660 El Torito boot catalog
1002 entries as EFI instead of overloading the i386 tag as done previously.
1003 The amd64 mkisoimages.sh script used to build amd64 ISO images for
1004 release was updated to use this. This may mean that makefs must be
1005 updated before "make cdrom" can be run in the release directory. This
1006 should be as simple as:
1008 $ cd $SRCDIR/usr.sbin/makefs
1009 $ make depend all install
1012 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
1013 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
1014 Co-existence for the transition period will come shortly. Booting is a
1015 complex environment and test coverage for Lua-enabled loaders has been
1016 thin, so it would be prudent to assume it might not work and make
1017 provisions for backup boot methods.
1020 devmatch functionality has been turned on in devd. It will automatically
1021 load drivers for unattached devices. This may cause unexpected drivers
1022 to be loaded. Please report any problems to current@ and
1026 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
1027 6.0.0. Please see the 20141231 entry below for information about
1028 prerequisites and upgrading, if you are not already using clang 3.5.0
1032 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
1033 This means it is used to link the kernel and userland libraries and
1034 executables, but is not yet installed as /usr/bin/ld by default.
1036 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
1037 WITHOUT_LLD_BOOTSTRAP=yes
1040 On i386, pmtimer has been removed. Its functionality has been folded
1041 into apm. It was a no-op on ACPI in current for a while now (but was
1042 still needed on i386 in FreeBSD 11 and earlier). Users may need to
1043 remove it from kernel config files.
1046 The use of RSS hash from the network card aka flowid has been
1047 disabled by default for lagg(4) as it's currently incompatible with
1048 the lacp and loadbalance protocols.
1050 This can be re-enabled by setting the following in loader.conf:
1051 net.link.lagg.default_use_flowid="1"
1054 The SW_WATCHDOG option is no longer necessary to enable the
1055 hardclock-based software watchdog if no hardware watchdog is
1056 configured. As before, SW_WATCHDOG will cause the software
1057 watchdog to be enabled even if a hardware watchdog is configured.
1060 r326887 fixes the issue described in the 20171214 UPDATING entry.
1061 r326888 flips the switch back to building GELI support always.
1064 r362593 broke ZFS + GELI support for reasons unknown. However,
1065 it also broke ZFS support generally, so GELI has been turned off
1066 by default as the lesser evil in r326857. If you boot off ZFS and/or
1067 GELI, it might not be a good time to update.
1070 PowerPC users must update loader(8) by rebuilding world before
1071 installing a new kernel, as the protocol connecting them has
1072 changed. Without the update, loader metadata will not be passed
1073 successfully to the kernel and users will have to enter their
1074 root partition at the kernel mountroot prompt to continue booting.
1075 Newer versions of loader can boot old kernels without issue.
1078 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
1079 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
1080 to WITH/OUT_LOADER_GELI.
1083 The naive and non-compliant support of posix_fallocate(2) in ZFS
1084 has been removed as of r325320. The system call now returns EINVAL
1085 when used on a ZFS file. Although the new behavior complies with the
1086 standard, some consumers are not prepared to cope with it.
1087 One known victim is lld prior to r325420.
1090 Building in a FreeBSD src checkout will automatically create object
1091 directories now rather than store files in the current directory if
1092 'make obj' was not ran. Calling 'make obj' is no longer necessary.
1093 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
1094 /etc/src-env.conf (not /etc/src.conf), or passing the option in the
1098 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
1099 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
1100 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
1101 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
1102 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
1103 The UNIFIED_OBJDIR option is a transitional feature that will be
1104 removed for 12.0 release; please migrate to the new format for any
1105 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
1106 than hardcoding paths.
1109 The native-xtools target no longer installs the files by default to the
1110 OBJDIR. Use the native-xtools-install target with a DESTDIR to install
1111 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
1114 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
1115 options are changing from controlling the build if defined / undefined
1116 to controlling the build with explicit 'yes' or 'no' values. They will
1117 shift to WITH/WITHOUT options to match other options in the system.
1120 libstand has turned into a private library for sys/boot use only.
1121 It is no longer supported as a public interface outside of sys/boot.
1124 The arm port has split armv6 into armv6 and armv7. armv7 is now
1125 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
1126 and are running a kernel from before r324363, you will need to add
1127 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
1130 When building multiple kernels using KERNCONF, non-existent KERNCONF
1131 files will produce an error and buildkernel will fail. Previously
1132 missing KERNCONF files silently failed giving no indication as to
1133 why, only to subsequently discover during installkernel that the
1134 desired kernel was never built in the first place.
1137 The default serial number format for CTL LUNs has changed. This will
1138 affect users who use /dev/diskid/* device nodes, or whose FibreChannel
1139 or iSCSI clients care about their LUNs' serial numbers. Users who
1140 require serial number stability should hardcode serial numbers in
1144 For 32-bit arm compiled for hard-float support, soft-floating point
1145 binaries now always get their shared libraries from
1146 LD_SOFT_LIBRARY_PATH (in the past, this was only used if
1147 /usr/libsoft also existed). Only users with a hard-float ld.so, but
1148 soft-float everything else should be affected.
1151 The geli password typed at boot is now hidden. To restore the previous
1152 behavior, see geli(8) for configuration options.
1155 Move PMTUD blackhole counters to TCPSTATS and remove them from bare
1156 sysctl values. Minor nit, but requires a rebuild of both world/kernel
1160 "make check" behavior (made in ^/head@r295380) has been changed to
1161 execute from a limited sandbox, as opposed to executing from
1165 - The "beforecheck" and "aftercheck" targets are now specified.
1166 - ${CHECKDIR} (added in commit noted above) has been removed.
1167 - Legacy behavior can be enabled by setting
1168 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
1170 If the limited sandbox mode is enabled, "make check" will execute
1171 "make distribution", then install, execute the tests, and clean up the
1172 sandbox if successful.
1174 The "make distribution" and "make install" targets are typically run as
1175 root to set appropriate permissions and ownership at installation time.
1176 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
1177 environment if executing "make check" with limited sandbox mode using
1178 an unprivileged user.
1181 Since the switch to GPT disk labels, fsck for UFS/FFS has been
1182 unable to automatically find alternate superblocks. As of r322297,
1183 the information needed to find alternate superblocks has been
1184 moved to the end of the area reserved for the boot block.
1185 Filesystems created with a newfs of this vintage or later
1186 will create the recovery information. If you have a filesystem
1187 created prior to this change and wish to have a recovery block
1188 created for your filesystem, you can do so by running fsck in
1189 foreground mode (i.e., do not use the -p or -y options). As it
1190 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
1191 to which you should answer yes.
1194 As of r321665, an NFSv4 server configuration that services
1195 Kerberos mounts or clients that do not support the uid/gid in
1196 owner/owner_group string capability, must explicitly enable
1197 the nfsuserd daemon by adding nfsuserd_enable="YES" to the
1198 machine's /etc/rc.conf file.
1201 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
1202 Please see the 20141231 entry below for information about prerequisites
1203 and upgrading, if you are not already using clang 3.5.0 or higher.
1206 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
1207 r-commands (rlogin, rsh, etc.) to be built with the base system.
1210 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
1211 a very major ABI incompatible change, so users of FreeBSD/powerpc must
1212 be careful when performing source upgrades. It is best to run
1213 'make installworld' from an alternate root system, either a live
1214 CD/memory stick, or a temporary root partition. Additionally, all ports
1215 must be recompiled. powerpc64 is largely unaffected, except in the case
1216 of 32-bit compatibility. All 32-bit binaries will be affected.
1219 Forward compatibility for the "ino64" project have been committed. This
1220 will allow most new binaries to run on older kernels in a limited
1221 fashion. This prevents many of the common foot-shooting actions in the
1222 upgrade as well as the limited ability to roll back the kernel across
1223 the ino64 upgrade. Complicated use cases may not work properly, though
1224 enough simpler ones work to allow recovery in most situations.
1227 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
1228 if you require the GPL compiler.
1231 The internal ABI used for communication between the NFS kernel modules
1232 was changed by r320085, so __FreeBSD_version was bumped to
1233 ensure all the NFS related modules are updated together.
1236 The ABI of struct event was changed by extending the data
1237 member to 64bit and adding ext fields. For upgrade, same
1238 precautions as for the entry 20170523 "ino64" must be
1242 The GNU roff toolchain has been removed from base. To render manpages
1243 which are not supported by mandoc(1), man(1) can fallback on GNU roff
1244 from ports (and recommends to install it).
1245 To render roff(7) documents, consider using GNU roff from ports or the
1246 heirloom doctools roff toolchain from ports via pkg install groff or
1247 via pkg install heirloom-doctools.
1250 The ath(4) and ath_hal(4) modules now build piecemeal to allow for
1251 smaller runtime footprint builds. This is useful for embedded systems
1252 which only require one chipset support.
1254 If you load it as a module, make sure this is in /boot/loader.conf:
1258 This will load the HAL, all chip/RF backends and if_ath_pci.
1259 If you have if_ath_pci in /boot/loader.conf, ensure it is after
1260 if_ath or it will not load any HAL chipset support.
1262 If you want to selectively load things (eg on ye cheape ARM/MIPS
1263 platforms where RAM is at a premium) you should:
1266 * load the chip modules in question
1267 * load ath_rate, ath_dfs
1269 * load if_ath_pci and/or if_ath_ahb depending upon your particular
1270 bus bind type - this is where probe/attach is done.
1272 For further comments/feedback, poke adrian@ .
1275 The "ino64" 64-bit inode project has been committed, which extends
1276 a number of types to 64 bits. Upgrading in place requires care and
1277 adherence to the documented upgrade procedure.
1279 If using a custom kernel configuration ensure that the
1280 COMPAT_FREEBSD11 option is included (as during the upgrade the
1281 system will be running the ino64 kernel with the existing world).
1283 For the safest in-place upgrade begin by removing previous build
1284 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full
1285 procedure documented below under the heading "To rebuild everything and
1286 install it on the current system." Specifically, a reboot is required
1287 after installing the new kernel before installing world. While an
1288 installworld normally works by accident from multiuser after rebooting
1289 the proper kernel, there are many cases where this will fail across this
1290 upgrade and installworld from single user is required.
1293 The NATM framework including the en(4), fatm(4), hatm(4), and
1294 patm(4) devices has been removed. Consumers should plan a
1295 migration before the end-of-life date for FreeBSD 11.
1298 GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1299 diff has not been implemented, if those are needed a newer version of
1300 GNU diff is available via the diffutils package under the gdiff name.
1303 As of r316810 for ipfilter, keep frags is no longer assumed when
1304 keep state is specified in a rule. r316810 aligns ipfilter with
1305 documentation in man pages separating keep frags from keep state.
1306 This allows keep state to be specified without forcing keep frags
1307 and allows keep frags to be specified independently of keep state.
1308 To maintain previous behaviour, also specify keep frags with
1309 keep state (as documented in ipf.conf.5).
1312 arm64 builds now use the base system LLD 4.0.0 linker by default,
1313 instead of requiring that the aarch64-binutils port or package be
1314 installed. To continue using aarch64-binutils, set
1315 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
1318 The UDP optimization in entry 20160818 that added the sysctl
1319 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
1320 packets will no longer be treated as L3 broadcast packets.
1323 Binds and sends to the loopback addresses, IPv6 and IPv4, will now
1324 use any explicitly assigned loopback address available in the jail
1325 instead of using the first assigned address of the jail.
1328 The ctl.ko module no longer implements the iSCSI target frontend:
1329 cfiscsi.ko does instead.
1331 If building cfiscsi.ko as a kernel module, the module can be loaded
1332 via one of the following methods:
1333 - `cfiscsi_load="YES"` in loader.conf(5).
1334 - Add `cfiscsi` to `$kld_list` in rc.conf(5).
1335 - ctladm(8)/ctld(8), when compiled with iSCSI support
1336 (`WITH_ISCSI=yes` in src.conf(5))
1338 Please see cfiscsi(4) for more details.
1341 The mmcsd.ko module now additionally depends on geom_flashmap.ko.
1342 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
1343 same source (previously, the dependency of mmcsd.ko on mmc.ko was
1344 missing, but mmcsd.ko now will refuse to load if it is incompatible
1348 The syntax of ipfw(8) named states was changed to avoid ambiguity.
1349 If you have used named states in the firewall rules, you need to modify
1350 them after installworld and before rebooting. Now named states must
1351 be prefixed with colon.
1354 The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1355 removed as the userland we provide cannot use them. The KMS version
1356 (sys/dev/drm2) supports the same hardware.
1359 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
1360 Please see the 20141231 entry below for information about prerequisites
1361 and upgrading, if you are not already using clang 3.5.0 or higher.
1364 The code that provides support for ZFS .zfs/ directory functionality
1365 has been reimplemented. It's not possible now to create a snapshot
1366 by mkdir under .zfs/snapshot/. That should be the only user visible
1370 EISA bus support has been removed. The WITH_EISA option is no longer
1374 MCA bus support has been removed.
1377 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1378 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
1381 The EM_MULTIQUEUE kernel configuration option is deprecated now that
1382 the em(4) driver conforms to iflib specifications.
1385 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1386 IFLIB. If you have a custom kernel configuration that excludes em(4)
1387 but you use igb(4), you need to re-add em(4) to your custom
1391 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
1392 Please see the 20141231 entry below for information about prerequisites
1393 and upgrading, if you are not already using clang 3.5.0 or higher.
1396 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
1397 Please see the 20141231 entry below for information about prerequisites
1398 and upgrading, if you are not already using clang 3.5.0 or higher.
1401 The layout of the pmap structure has changed for powerpc to put the pmap
1402 statistics at the front for all CPU variations. libkvm(3) and all tools
1403 that link against it need to be recompiled.
1406 isl(4) and cyapa(4) drivers now require a new driver,
1407 chromebook_platform(4), to work properly on Chromebook-class hardware.
1408 On other types of hardware the drivers may need to be configured using
1409 device hints. Please see the corresponding manual pages for details.
1412 The urtwn(4) driver was merged into rtwn(4) and now consists of
1413 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
1415 Also, firmware for RTL8188CE was renamed due to possible name
1416 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
1419 GNU rcs has been removed from base. It is available as packages:
1420 - rcs: Latest GPLv3 GNU rcs version.
1421 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
1425 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1426 modules now requires that the kernel configuration contain the
1427 TCP_HHOOK option. (This option is included in the GENERIC kernel.)
1430 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
1431 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
1434 Relocatable object files with the extension of .So have been renamed
1435 to use an extension of .pico instead. The purpose of this change is
1436 to avoid a name clash with shared libraries on case-insensitive file
1437 systems. On those file systems, foo.So is the same file as foo.so.
1440 GNU rcs has been turned off by default. It can (temporarily) be built
1441 again by adding WITH_RCS knob in src.conf.
1442 Otherwise, GNU rcs is available from packages:
1443 - rcs: Latest GPLv3 GNU rcs version.
1444 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
1447 The backup_uses_rcs functionality has been removed from rc.subr.
1450 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
1451 two separate components, QUEUE_MACRO_DEBUG_TRACE and
1452 QUEUE_MACRO_DEBUG_TRASH. Define both for the original
1453 QUEUE_MACRO_DEBUG behavior.
1456 r304787 changed some ioctl interfaces between the iSCSI userspace
1457 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
1458 rebuilt to work with new kernels. __FreeBSD_version has been bumped
1462 The UDP receive code has been updated to only treat incoming UDP
1463 packets that were addressed to an L2 broadcast address as L3
1464 broadcast packets. It is not expected that this will affect any
1465 standards-conforming UDP application. The new behaviour can be
1466 disabled by setting the sysctl net.inet.udp.require_l2_bcast to
1470 Remove the openbsd_poll system call.
1471 __FreeBSD_version has been bumped because of this.
1474 The stable/11 branch has been created from head@r302406.
1477 The libc stub for the pipe(2) system call has been replaced with
1478 a wrapper that calls the pipe2(2) system call and the pipe(2)
1479 system call is now only implemented by the kernels that include
1480 "options COMPAT_FREEBSD10" in their config file (this is the
1481 default). Users should ensure that this option is enabled in
1482 their kernel or upgrade userspace to r302092 before upgrading their
1486 CAM will now strip leading spaces from SCSI disks' serial numbers.
1487 This will affect users who create UFS filesystems on SCSI disks using
1488 those disk's diskid device nodes. For example, if /etc/fstab
1489 previously contained a line like
1490 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1491 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
1492 transforms like gmirror may also be affected. ZFS users should
1496 The bitstring(3) API has been updated with new functionality and
1497 improved performance. But it is binary-incompatible with the old API.
1498 Objects built with the new headers may not be linked against objects
1499 built with the old headers.
1502 The brk and sbrk functions have been removed from libc on arm64.
1503 Binutils from ports has been updated to not link to these
1504 functions and should be updated to the latest version before
1505 installing a new libc.
1508 The armv6 port now defaults to hard float ABI. Limited support
1509 for running both hardfloat and soft float on the same system
1510 is available using the libraries installed with -DWITH_LIBSOFT.
1511 This has only been tested as an upgrade path for installworld
1512 and packages may fail or need manual intervention to run. New
1513 packages will be needed.
1515 To update an existing self-hosted armv6hf system, you must add
1516 TARGET_ARCH=armv6 on the make command line for both the build
1517 and the install steps.
1520 Kernel modules compiled outside of a kernel build now default to
1521 installing to /boot/modules instead of /boot/kernel. Many kernel
1522 modules built this way (such as those in ports) already overrode
1523 KMODDIR explicitly to install into /boot/modules. However,
1524 manually building and installing a module from /sys/modules will
1525 now install to /boot/modules instead of /boot/kernel.
1528 The CAM I/O scheduler has been committed to the kernel. There should be
1529 no user visible impact. This does enable NCQ Trim on ada SSDs. While the
1530 list of known rogues that claim support for this but actually corrupt
1531 data is believed to be complete, be on the lookout for data
1532 corruption. The known rogue list is believed to be complete:
1534 o Crucial MX100, M550 drives with MU01 firmware.
1535 o Micron M510 and M550 drives with MU01 firmware.
1536 o Micron M500 prior to MU07 firmware
1537 o Samsung 830, 840, and 850 all firmwares
1538 o FCCT M500 all firmwares
1540 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1541 with working NCQ TRIM. For Micron branded drives, see your sales rep for
1542 updated firmware. Black listed drives will work correctly because these
1543 drives work correctly so long as no NCQ TRIMs are sent to them. Given
1544 this list is the same as found in Linux, it's believed there are no
1545 other rogues in the market place. All other models from the above
1548 To be safe, if you are at all concerned, you can quirk each of your
1549 drives to prevent NCQ from being sent by setting:
1550 kern.cam.ada.X.quirks="0x2"
1551 in loader.conf. If the drive requires the 4k sector quirk, set the
1552 quirks entry to 0x3.
1555 The FAST_DEPEND build option has been removed and its functionality is
1556 now the one true way. The old mkdep(1) style of 'make depend' has
1557 been removed. See 20160311 for further details.
1560 Resource range types have grown from unsigned long to uintmax_t. All
1561 drivers, and anything using libdevinfo, need to be recompiled.
1564 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1565 builds. It no longer runs mkdep(1) during 'make depend', and the
1566 'make depend' stage can safely be skipped now as it is auto ran
1567 when building 'make all' and will generate all SRCS and DPSRCS before
1568 building anything else. Dependencies are gathered at compile time with
1569 -MF flags kept in separate .depend files per object file. Users should
1570 run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1571 stale .depend files.
1574 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1575 kernel modules. Therefore, if you load any kernel modules at boot time,
1576 please install the boot loaders after you install the kernel, but before
1580 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1581 make installkernel KERNCONF=YOUR_KERNEL_HERE
1582 make -C sys/boot install
1583 <reboot in single user>
1585 Then follow the usual steps, described in the General Notes section,
1589 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
1590 see the 20141231 entry below for information about prerequisites and
1591 upgrading, if you are not already using clang 3.5.0 or higher.
1594 The AIO subsystem is now a standard part of the kernel. The
1595 VFS_AIO kernel option and aio.ko kernel module have been removed.
1596 Due to stability concerns, asynchronous I/O requests are only
1597 permitted on sockets and raw disks by default. To enable
1598 asynchronous I/O requests on all file types, set the
1599 vfs.aio.enable_unsafe sysctl to a non-zero value.
1602 The ELF object manipulation tool objcopy is now provided by the
1603 ELF Tool Chain project rather than by GNU binutils. It should be a
1604 drop-in replacement, with the addition of arm64 support. The
1605 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1606 to obtain the GNU version if necessary.
1609 Building ZFS pools on top of zvols is prohibited by default. That
1610 feature has never worked safely; it's always been prone to deadlocks.
1611 Using a zvol as the backing store for a VM guest's virtual disk will
1612 still work, even if the guest is using ZFS. Legacy behavior can be
1613 restored by setting vfs.zfs.vol.recursive=1.
1616 The NONE and HPN patches has been removed from OpenSSH. They are
1617 still available in the security/openssh-portable port.
1620 With the addition of ypldap(8), a new _ypldap user is now required
1621 during installworld. "mergemaster -p" can be used to add the user
1622 prior to installworld, as documented in the handbook.
1625 The tftp loader (pxeboot) now uses the option root-path directive. As a
1626 consequence it no longer looks for a pxeboot.4th file on the tftp
1627 server. Instead it uses the regular /boot infrastructure as with the
1631 The code to start recording plug and play data into the modules has
1632 been committed. While the old tools will properly build a new kernel,
1633 a number of warnings about "unknown metadata record 4" will be produced
1634 for an older kldxref. To avoid such warnings, make sure to rebuild
1635 the kernel toolchain (or world). Make sure that you have r292078 or
1636 later when trying to build 292077 or later before rebuilding.
1639 Debug data files are now built by default with 'make buildworld' and
1640 installed with 'make installworld'. This facilitates debugging but
1641 requires more disk space both during the build and for the installed
1642 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1646 r291527 changed the internal interface between the nfsd.ko and
1647 nfscommon.ko modules. As such, they must both be upgraded to-gether.
1648 __FreeBSD_version has been bumped because of this.
1651 Add support for unicode collation strings leads to a change of
1652 order of files listed by ls(1) for example. To get back to the old
1653 behaviour, set LC_COLLATE environment variable to "C".
1655 Databases administrators will need to reindex their databases given
1656 collation results will be different.
1658 Due to a bug in install(1) it is recommended to remove the ancient
1659 locales before running make installworld.
1661 rm -rf /usr/share/locale/*
1664 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
1665 libcrypto.so.7 or libssl.so.7 must be recompiled.
1668 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1669 Kernel modules isp_2400_multi and isp_2500_multi were removed and
1670 should be replaced with isp_2400 and isp_2500 modules respectively.
1673 The build previously allowed using 'make -n' to not recurse into
1674 sub-directories while showing what commands would be executed, and
1675 'make -n -n' to recursively show commands. Now 'make -n' will recurse
1676 and 'make -N' will not.
1679 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1680 and etcupdate will now use this file. A custom sendmail.cf is now
1681 updated via this mechanism rather than via installworld. If you had
1682 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1683 want to remove the exclusion or change it to "always install".
1684 /etc/mail/sendmail.cf is now managed the same way regardless of
1685 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
1686 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1689 Compatibility shims for legacy ATA device names have been removed.
1690 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
1691 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
1692 environment variables, /dev/ad* and /dev/ar* symbolic links.
1695 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
1696 Please see the 20141231 entry below for information about prerequisites
1697 and upgrading, if you are not already using clang 3.5.0 or higher.
1700 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
1701 and renamed from .symbols to .debug. This reduces the size requirements
1702 on the boot partition or file system and provides consistency with
1703 userland debug files.
1705 When using the supported kernel installation method the
1706 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
1707 as is done with /boot/kernel.
1709 Developers wishing to maintain the historical behavior of installing
1710 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
1713 The wireless drivers had undergone changes that remove the 'parent
1714 interface' from the ifconfig -l output. The rc.d network scripts
1715 used to check presence of a parent interface in the list, so old
1716 scripts would fail to start wireless networking. Thus, etcupdate(3)
1717 or mergemaster(8) run is required after kernel update, to update your
1718 rc.d scripts in /etc.
1721 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
1722 These configurations are now automatically interpreted as
1723 'scrub fragment reassemble'.
1726 Kernel-loadable modules for the random(4) device are back. To use
1727 them, the kernel must have
1730 options RANDOM_LOADABLE
1732 kldload(8) can then be used to load random_fortuna.ko
1733 or random_yarrow.ko. Please note that due to the indirect
1734 function calls that the loadable modules need to provide,
1735 the build-in variants will be slightly more efficient.
1737 The random(4) kernel option RANDOM_DUMMY has been retired due to
1738 unpopularity. It was not all that useful anyway.
1741 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
1742 Control over building the ELF Tool Chain tools is now provided by
1743 the WITHOUT_TOOLCHAIN knob.
1746 The polarity of Pulse Per Second (PPS) capture events with the
1747 uart(4) driver has been corrected. Prior to this change the PPS
1748 "assert" event corresponded to the trailing edge of a positive PPS
1749 pulse and the "clear" event was the leading edge of the next pulse.
1751 As the width of a PPS pulse in a typical GPS receiver is on the
1752 order of 1 millisecond, most users will not notice any significant
1753 difference with this change.
1755 Anyone who has compensated for the historical polarity reversal by
1756 configuring a negative offset equal to the pulse width will need to
1757 remove that workaround.
1760 The default group assigned to /dev/dri entries has been changed
1761 from 'wheel' to 'video' with the id of '44'. If you want to have
1762 access to the dri devices please add yourself to the video group
1765 # pw groupmod video -m $USER
1768 The menu.rc and loader.rc files will now be replaced during
1769 upgrades. Please migrate local changes to menu.rc.local and
1770 loader.rc.local instead.
1773 GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1774 strings and strip have been removed. The src.conf(5) knob
1775 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1778 As ZFS requires more kernel stack pages than is the default on some
1779 architectures e.g. i386, it now warns if KSTACK_PAGES is less than
1780 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
1782 Please consider using 'options KSTACK_PAGES=X' where X is greater
1783 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
1786 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
1787 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1788 default, i.e., they will not contain "::". For example, instead
1789 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
1790 to have a more specific match, such as different map entries for
1791 IPv6:0:0 vs IPv6:0. This change requires that configuration
1792 data (including maps, files, classes, custom ruleset, etc.) must
1793 use the same format, so make certain such configuration data is
1794 upgrading. As a very simple check search for patterns like
1795 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
1796 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1797 the cf option UseCompressedIPv6Addresses.
1800 The default kernel entropy-processing algorithm is now
1801 Fortuna, replacing Yarrow.
1803 Assuming you have 'device random' in your kernel config
1804 file, the configurations allow a kernel option to override
1805 this default. You may choose *ONE* of:
1807 options RANDOM_YARROW # Legacy /dev/random algorithm.
1808 options RANDOM_DUMMY # Blocking-only driver.
1810 If you have neither, you get Fortuna. For most people,
1811 read no further, Fortuna will give a /dev/random that works
1812 like it always used to, and the difference will be irrelevant.
1814 If you remove 'device random', you get *NO* kernel-processed
1815 entropy at all. This may be acceptable to folks building
1816 embedded systems, but has complications. Carry on reading,
1817 and it is assumed you know what you need.
1819 *PLEASE* read random(4) and random(9) if you are in the
1820 habit of tweaking kernel configs, and/or if you are a member
1821 of the embedded community, wanting specific and not-usual
1822 behaviour from your security subsystems.
1824 NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1825 random', you will NOT have a functioning /dev/random, and
1826 many cryptographic features will not work, including SSH.
1827 You may also find strange behaviour from the random(3) set
1828 of library functions, in particular sranddev(3), srandomdev(3)
1829 and arc4random(3). The reason for this is that the KERN_ARND
1830 sysctl only returns entropy if it thinks it has some to
1831 share, and with RANDOM_DUMMY or no 'device random' this
1835 An additional fix for the issue described in the 20150614 sendmail
1836 entry below has been committed in revision 284717.
1839 FreeBSD's old make (fmake) has been removed from the system. It is
1840 available as the devel/fmake port or via pkg install fmake.
1843 The fix for the issue described in the 20150614 sendmail entry
1844 below has been committed in revision 284436. The work
1845 around described in that entry is no longer needed unless the
1846 default setting is overridden by a confDH_PARAMETERS configuration
1847 setting of '5' or pointing to a 512 bit DH parameter file.
1850 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
1851 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
1852 and devel/kyua to version 0.20+ and adjust any calling code to work
1853 with Kyuafile and kyua.
1856 The import of openssl to address the FreeBSD-SA-15:10.openssl
1857 security advisory includes a change which rejects handshakes
1858 with DH parameters below 768 bits. sendmail releases prior
1859 to 8.15.2 (not yet released), defaulted to a 512 bit
1860 DH parameter setting for client connections. To work around
1861 this interoperability, sendmail can be configured to use a
1862 2048 bit DH parameter by:
1864 1. Edit /etc/mail/`hostname`.mc
1865 2. If a setting for confDH_PARAMETERS does not exist or
1866 exists and is set to a string beginning with '5',
1867 replace it with '2'.
1868 3. If a setting for confDH_PARAMETERS exists and is set to
1869 a file path, create a new file with:
1870 openssl dhparam -out /path/to/file 2048
1871 4. Rebuild the .cf file:
1872 cd /etc/mail/; make; make install
1873 5. Restart sendmail:
1874 cd /etc/mail/; make restart
1876 A sendmail patch is coming, at which time this file will be
1880 Generation of legacy formatted entries have been disabled by default
1881 in pwd_mkdb(8), as all base system consumers of the legacy formatted
1882 entries were converted to use the new format by default when the new,
1883 machine independent format have been added and supported since FreeBSD
1886 Please see the pwd_mkdb(8) manual page for further details.
1889 Clang and llvm have been upgraded to 3.6.1 release. Please see the
1890 20141231 entry below for information about prerequisites and upgrading,
1891 if you are not already using 3.5.0 or higher.
1894 TI platform code switched to using vendor DTS files and this update
1895 may break existing systems running on Beaglebone, Beaglebone Black,
1898 - dtb files should be regenerated/reinstalled. Filenames are the
1899 same but content is different now
1900 - GPIO addressing was changed, now each GPIO bank (32 pins per bank)
1901 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
1902 addressing scheme is now pin 25 on /dev/gpioc3.
1903 - Pandaboard: /etc/ttys should be updated, serial console device is
1904 now /dev/ttyu2, not /dev/ttyu0
1907 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
1908 If you need the GNU extension from groff soelim(1), install groff
1909 from package: pkg install groff, or via ports: textproc/groff.
1912 chmod, chflags, chown and chgrp now affect symlinks in -R mode as
1913 defined in symlink(7); previously symlinks were silently ignored.
1916 The const qualifier has been removed from iconv(3) to comply with
1917 POSIX. The ports tree is aware of this from r384038 onwards.
1920 Libraries specified by LIBADD in Makefiles must have a corresponding
1921 DPADD_<lib> variable to ensure correct dependencies. This is now
1922 enforced in src.libnames.mk.
1925 From legacy ata(4) driver was removed support for SATA controllers
1926 supported by more functional drivers ahci(4), siis(4) and mvs(4).
1927 Kernel modules ataahci and ataadaptec were removed completely,
1928 replaced by ahci and mvs modules respectively.
1931 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
1932 the 20141231 entry below for information about prerequisites and
1933 upgrading, if you are not already using 3.5.0 or higher.
1936 The 32-bit PowerPC kernel has been changed to a position-independent
1937 executable. This can only be booted with a version of loader(8)
1938 newer than January 31, 2015, so make sure to update both world and
1939 kernel before rebooting.
1942 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
1943 but before r278950, the RNG was not seeded properly. Immediately
1944 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
1945 ssh keys or openssl keys) that were generated w/ a kernel from that
1946 range. This does not affect programs that directly used /dev/random
1947 or /dev/urandom. All userland uses of arc4random(3) are affected.
1950 The autofs(4) ABI was changed in order to restore binary compatibility
1951 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
1952 with the new kernel.
1955 The powerpc64 kernel has been changed to a position-independent
1956 executable. This can only be booted with a new version of loader(8),
1957 so make sure to update both world and kernel before rebooting.
1960 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
1961 only release, no new features have been added. Please see the 20141231
1962 entry below for information about prerequisites and upgrading, if you
1963 are not already using 3.5.0.
1966 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
1967 taken from the ELF Tool Chain project rather than GNU binutils. They
1968 should be drop-in replacements, with the addition of arm64 support.
1969 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
1970 binutils tools, if necessary. See 20150805 for updated information.
1973 The default Unbound configuration now enables remote control
1974 using a local socket. Users who have already enabled the
1975 local_unbound service should regenerate their configuration
1976 by running "service local_unbound setup" as root.
1979 The GNU texinfo and GNU info pages have been removed.
1980 To be able to view GNU info pages please install texinfo from ports.
1983 Clang, llvm and lldb have been upgraded to 3.5.0 release.
1985 As of this release, a prerequisite for building clang, llvm and lldb is
1986 a C++11 capable compiler and C++11 standard library. This means that to
1987 be able to successfully build the cross-tools stage of buildworld, with
1988 clang as the bootstrap compiler, your system compiler or cross compiler
1989 should either be clang 3.3 or later, or gcc 4.8 or later, and your
1990 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
1993 On any standard FreeBSD 10.x or 11.x installation, where clang and
1994 libc++ are on by default (that is, on x86 or arm), this should work out
1997 On 9.x installations where clang is enabled by default, e.g. on x86 and
1998 powerpc, libc++ will not be enabled by default, so libc++ should be
1999 built (with clang) and installed first. If both clang and libc++ are
2000 missing, build clang first, then use it to build libc++.
2002 On 8.x and earlier installations, upgrade to 9.x first, and then follow
2003 the instructions for 9.x above.
2005 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
2006 default, and do not build clang.
2008 Many embedded systems are resource constrained, and will not be able to
2009 build clang in a reasonable time, or in some cases at all. In those
2010 cases, cross building bootable systems on amd64 is a workaround.
2012 This new version of clang introduces a number of new warnings, of which
2013 the following are most likely to appear:
2017 This warns in two cases, for both C and C++:
2018 * When the code is trying to take the absolute value of an unsigned
2019 quantity, which is effectively a no-op, and almost never what was
2020 intended. The code should be fixed, if at all possible. If you are
2021 sure that the unsigned quantity can be safely cast to signed, without
2022 loss of information or undefined behavior, you can add an explicit
2023 cast, or disable the warning.
2025 * When the code is trying to take an absolute value, but the called
2026 abs() variant is for the wrong type, which can lead to truncation.
2027 If you want to disable the warning instead of fixing the code, please
2028 make sure that truncation will not occur, or it might lead to unwanted
2031 -Wtautological-undefined-compare and
2032 -Wundefined-bool-conversion
2034 These warn when C++ code is trying to compare 'this' against NULL, while
2035 'this' should never be NULL in well-defined C++ code. However, there is
2036 some legacy (pre C++11) code out there, which actively abuses this
2037 feature, which was less strictly defined in previous C++ versions.
2039 Squid and openjdk do this, for example. The warning can be turned off
2040 for C++98 and earlier, but compiling the code in C++11 mode might result
2041 in unexpected behavior; for example, the parts of the program that are
2042 unreachable could be optimized away.
2045 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
2046 kernel sources have been removed. The .h files remain, since some
2047 utilities include them. This will need to be fixed later.
2048 If "mount -t oldnfs ..." is attempted, it will fail.
2049 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
2050 the utilities will report errors.
2053 The handling of LOCAL_LIB_DIRS has been altered to skip addition of
2054 directories to top level SUBDIR variable when their parent
2055 directory is included in LOCAL_DIRS. Users with build systems with
2056 such hierarchies and without SUBDIR entries in the parent
2057 directory Makefiles should add them or add the directories to
2061 faith(4) and faithd(8) have been removed from the base system. Faith
2062 has been obsolete for a very long time.
2065 vt(4), the new console driver, is enabled by default. It brings
2066 support for Unicode and double-width characters, as well as
2067 support for UEFI and integration with the KMS kernel video
2070 You may need to update your console settings in /etc/rc.conf,
2071 most probably the keymap. During boot, /etc/rc.d/syscons will
2072 indicate what you need to do.
2074 vt(4) still has issues and lacks some features compared to
2075 syscons(4). See the wiki for up-to-date information:
2076 https://wiki.freebsd.org/Newcons
2078 If you want to keep using syscons(4), you can do so by adding
2079 the following line to /boot/loader.conf:
2083 pjdfstest has been integrated into kyua as an opt-in test suite.
2084 Please see share/doc/pjdfstest/README for more details on how to
2088 gperf has been removed from the base system for architectures
2089 that use clang. Ports that require gperf will obtain it from the
2093 pjdfstest has been moved from tools/regression/pjdfstest to
2097 At svn r271982, The default linux compat kernel ABI has been adjusted
2098 to 2.6.18 in support of the linux-c6 compat ports infrastructure
2099 update. If you wish to continue using the linux-f10 compat ports,
2100 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
2101 encouraged to update their linux-compat packages to linux-c6 during
2102 their next update cycle.
2105 The ofwfb driver, used to provide a graphics console on PowerPC when
2106 using vt(4), no longer allows mmap() of all physical memory. This
2107 will prevent Xorg on PowerPC with some ATI graphics cards from
2108 initializing properly unless x11-servers/xorg-server is updated to
2112 The xdev targets have been converted to using TARGET and
2113 TARGET_ARCH instead of XDEV and XDEV_ARCH.
2116 The default unbound configuration has been modified to address
2117 issues with reverse lookups on networks that use private
2118 address ranges. If you use the local_unbound service, run
2119 "service local_unbound setup" as root to regenerate your
2120 configuration, then "service local_unbound reload" to load the
2124 The GNU texinfo and GNU info pages are not built and installed
2125 anymore, WITH_INFO knob has been added to allow to built and install
2127 UPDATE: see 20150102 entry on texinfo's removal
2130 The GNU readline library is now an INTERNALLIB - that is, it is
2131 statically linked into consumers (GDB and variants) in the base
2132 system, and the shared library is no longer installed. The
2133 devel/readline port is available for third party software that
2137 The Itanium architecture (ia64) has been removed from the list of
2138 known architectures. This is the first step in the removal of the
2142 Commit r268115 has added NFSv4.1 server support, merged from
2143 projects/nfsv4.1-server. Since this includes changes to the
2144 internal interfaces between the NFS related modules, a full
2145 build of the kernel and modules will be necessary.
2146 __FreeBSD_version has been bumped.
2149 The WITHOUT_VT_SUPPORT kernel config knob has been renamed
2150 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
2151 which differs from the behaviour controlled by this knob.)
2154 Maximal length of the serial number in CTL was increased from 16 to
2155 64 chars, that breaks ABI. All CTL-related tools, such as ctladm
2156 and ctld, need to be rebuilt to work with a new kernel.
2159 The libatf-c and libatf-c++ major versions were downgraded to 0 and
2160 1 respectively to match the upstream numbers. They were out of
2161 sync because, when they were originally added to FreeBSD, the
2162 upstream versions were not respected. These libraries are private
2163 and not yet built by default, so renumbering them should be a
2164 non-issue. However, unclean source trees will yield broken test
2165 programs once the operator executes "make delete-old-libs" after a
2166 "make installworld".
2168 Additionally, the atf-sh binary was made private by moving it into
2169 /usr/libexec/. Already-built shell test programs will keep the
2170 path to the old binary so they will break after "make delete-old"
2173 If you are using WITH_TESTS=yes (not the default), wipe the object
2174 tree and rebuild from scratch to prevent spurious test failures.
2175 This is only needed once: the misnumbered libraries and misplaced
2176 binaries have been added to OptionalObsoleteFiles.inc so they will
2177 be removed during a clean upgrade.
2180 Clang and llvm have been upgraded to 3.4.1 release.
2183 We bogusly installed src.opts.mk in /usr/share/mk. This file should
2184 be removed to avoid issues in the future (and has been added to
2188 /etc/src.conf now affects only builds of the FreeBSD src tree. In the
2189 past, it affected all builds that used the bsd.*.mk files. The old
2190 behavior was a bug, but people may have relied upon it. To get this
2191 behavior back, you can .include /etc/src.conf from /etc/make.conf
2192 (which is still global and isn't changed). This also changes the
2193 behavior of incremental builds inside the tree of individual
2194 directories. Set MAKESYSPATH to ".../share/mk" to do that.
2195 Although this has survived make universe and some upgrade scenarios,
2196 other upgrade scenarios may have broken. At least one form of
2197 temporary breakage was fixed with MAKESYSPATH settings for buildworld
2198 as well... In cases where MAKESYSPATH isn't working with this
2199 setting, you'll need to set it to the full path to your tree.
2201 One side effect of all this cleaning up is that bsd.compiler.mk
2202 is no longer implicitly included by bsd.own.mk. If you wish to
2203 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2207 The lindev device has been removed since /dev/full has been made a
2208 standard device. __FreeBSD_version has been bumped.
2211 The knob WITHOUT_VI was added to the base system, which controls
2212 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2213 in order to reorder files share/termcap and didn't build ex(1) as a
2214 build tool, so building/installing with WITH_VI is highly advised for
2215 build hosts for older releases.
2217 This issue has been fixed in stable/9 and stable/10 in r277022 and
2218 r276991, respectively.
2221 The YES_HESIOD knob has been removed. It has been obsolete for
2222 a decade. Please move to using WITH_HESIOD instead or your builds
2223 will silently lack HESIOD.
2226 The uart(4) driver has been changed with respect to its handling
2227 of the low-level console. Previously the uart(4) driver prevented
2228 any process from changing the baudrate or the CLOCAL and HUPCL
2229 control flags. By removing the restrictions, operators can make
2230 changes to the serial console port without having to reboot.
2231 However, when getty(8) is started on the serial device that is
2232 associated with the low-level console, a misconfigured terminal
2233 line in /etc/ttys will now have a real impact.
2234 Before upgrading the kernel, make sure that /etc/ttys has the
2235 serial console device configured as 3wire without baudrate to
2236 preserve the previous behaviour. E.g:
2237 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
2240 Support for libwrap (TCP wrappers) in rpcbind was disabled by default
2241 to improve performance. To re-enable it, if needed, run rpcbind
2242 with command line option -W.
2245 Switched back to the GPL dtc compiler due to updates in the upstream
2246 dts files not being supported by the BSDL dtc compiler. You will need
2247 to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2248 may result while building dtb files during a kernel build if you fail
2249 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
2252 Clang and llvm have been upgraded to 3.4 release.
2255 The nve(4) driver has been removed. Please use the nfe(4) driver
2256 for NVIDIA nForce MCP Ethernet adapters instead.
2259 An ABI incompatibility crept into the libc++ 3.4 import in r261283.
2260 This could cause certain C++ applications using shared libraries built
2261 against the previous version of libc++ to crash. The incompatibility
2262 has now been fixed, but any C++ applications or shared libraries built
2263 between r261283 and r261801 should be recompiled.
2266 OpenSSH will now ignore errors caused by kernel lacking of Capsicum
2267 capability mode support. Please note that enabling the feature in
2268 kernel is still highly recommended.
2271 OpenSSH is now built with sandbox support, and will use sandbox as
2272 the default privilege separation method. This requires Capsicum
2273 capability mode support in kernel.
2276 The libelf and libdwarf libraries have been updated to newer
2277 versions from upstream. Shared library version numbers for
2278 these two libraries were bumped. Any ports or binaries
2279 requiring these two libraries should be recompiled.
2280 __FreeBSD_version is bumped to 1100006.
2283 If a Makefile in a tests/ directory was auto-generating a Kyuafile
2284 instead of providing an explicit one, this would prevent such
2285 Makefile from providing its own Kyuafile in the future during
2286 NO_CLEAN builds. This has been fixed in the Makefiles but manual
2287 intervention is needed to clean an objdir if you use NO_CLEAN:
2288 # find /usr/obj -name Kyuafile | xargs rm -f
2291 The behavior of gss_pseudo_random() for the krb5 mechanism
2292 has changed, for applications requesting a longer random string
2293 than produced by the underlying enctype's pseudo-random() function.
2294 In particular, the random string produced from a session key of
2295 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
2296 be different at the 17th octet and later, after this change.
2297 The counter used in the PRF+ construction is now encoded as a
2298 big-endian integer in accordance with RFC 4402.
2299 __FreeBSD_version is bumped to 1100004.
2302 The WITHOUT_ATF build knob has been removed and its functionality
2303 has been subsumed into the more generic WITHOUT_TESTS. If you were
2304 using the former to disable the build of the ATF libraries, you
2305 should change your settings to use the latter.
2308 The default version of mtree is nmtree which is obtained from
2309 NetBSD. The output is generally the same, but may vary
2310 slightly. If you found you need identical output adding
2311 "-F freebsd9" to the command line should do the trick. For the
2312 time being, the old mtree is available as fmtree.
2315 libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
2316 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
2317 1.1.4_8 and verify bsdyml not linked in, before running "make
2319 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
2321 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
2324 The stable/10 branch has been created in subversion from head
2331 Sometimes, obscure build problems are the result of environment
2332 poisoning. This can happen because the make utility reads its
2333 environment when searching for values for global variables. To run
2334 your build attempts in an "environmental clean room", prefix all make
2335 commands with 'env -i '. See the env(1) manual page for more details.
2336 Occasionally a build failure will occur with "make -j" due to a race
2337 condition. If this happens try building again without -j, and please
2338 report a bug if it happens consistently.
2340 When upgrading from one major version to another it is generally best to
2341 upgrade to the latest code in the currently installed branch first, then
2342 do an upgrade to the new branch. This is the best-tested upgrade path,
2343 and has the highest probability of being successful. Please try this
2344 approach if you encounter problems with a major version upgrade. Since
2345 the stable 4.x branch point, one has generally been able to upgrade from
2346 anywhere in the most recent stable branch to head / current (or even the
2347 last couple of stable branches). See the top of this file when there's
2350 The update process will emit an error on an attempt to perform a build
2351 or install from a FreeBSD version below the earliest supported version.
2352 When updating from an older version the update should be performed one
2353 major release at a time, including running `make delete-old` at each
2356 When upgrading a live system, having a root shell around before
2357 installing anything can help undo problems. Not having a root shell
2358 around can lead to problems if pam has changed too much from your
2359 starting point to allow continued authentication after the upgrade.
2361 This file should be read as a log of events. When a later event changes
2362 information of a prior event, the prior event should not be deleted.
2363 Instead, a pointer to the entry with the new information should be
2364 placed in the old entry. Readers of this file should also sanity check
2365 older entries before relying on them blindly. Authors of new entries
2366 should write them with this in mind.
2370 When upgrading the boot ZFS pool to a new version, always follow
2373 1.) recompile and reinstall the ZFS boot loader and boot block
2374 (this is part of "make buildworld" and "make installworld")
2376 2.) update the ZFS boot block on your boot drive
2378 The following example updates the ZFS boot block on the
2379 freebsd-boot partition of a GPT partitioned drive ada0:
2380 "gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2381 The value $N will typically be 1 (if booting from BIOS) or 2 (if
2384 Non-boot pools do not need these updates.
2388 If you are updating from a prior version of FreeBSD (even one just
2389 a few days old), you should follow this procedure. It is the most
2390 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
2392 make kernel-toolchain
2393 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
2394 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
2396 To test a kernel once
2397 ---------------------
2398 If you just want to boot a kernel once (because you are not sure
2399 if it works, or if you want to boot a known bad kernel to provide
2400 debugging information) run
2401 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
2402 nextboot -k testkernel
2404 To rebuild everything and install it on the current system.
2405 -----------------------------------------------------------
2406 # Note: sometimes if you are running current you gotta do more than
2407 # is listed here if you are upgrading from a really old current.
2409 <make sure you have good level 0 dumps>
2411 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2412 make installkernel KERNCONF=YOUR_KERNEL_HERE
2414 <reboot in single user> [3]
2421 To cross-install current onto a separate partition
2422 --------------------------------------------------
2423 # In this approach we use a separate partition to hold
2424 # current's root, 'usr', and 'var' directories. A partition
2425 # holding "/", "/usr" and "/var" should be about 2GB in
2428 <make sure you have good level 0 dumps>
2431 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2432 <maybe newfs current's root partition>
2433 <mount current's root partition on directory ${CURRENT_ROOT}>
2434 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
2435 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
2436 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
2437 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
2438 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
2439 <reboot into current>
2440 <do a "native" rebuild/install as described in the previous section>
2441 <maybe install compatibility libraries from ports/misc/compat*>
2445 To upgrade in-place from stable to current
2446 ----------------------------------------------
2447 <make sure you have good level 0 dumps>
2449 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
2450 make installkernel KERNCONF=YOUR_KERNEL_HERE
2452 <reboot in single user> [3]
2459 Make sure that you've read the UPDATING file to understand the
2460 tweaks to various things you need. At this point in the life
2461 cycle of current, things change often and you are on your own
2462 to cope. The defaults can also change, so please read ALL of
2463 the UPDATING entries.
2465 Also, if you are tracking -current, you must be subscribed to
2466 freebsd-current@freebsd.org. Make sure that before you update
2467 your sources that you have read and understood all the recent
2468 messages there. If in doubt, please track -stable which has
2469 much fewer pitfalls.
2471 [1] If you have third party modules, such as vmware, you should disable
2472 them at this point so they don't crash your system on
2473 reboot. Alternatively, you should rebuild all the modules you have in
2474 your system and install them as well. If you are running -current, you
2475 should seriously consider placing all sources to all the modules for
2476 your system (or symlinks to them) in /usr/local/sys/modules so this
2477 happens automatically. If all your modules come from ports, then adding
2478 the port origin directories to PORTS_MODULES instead is also automatic
2480 PORTS_MODULES+=x11/nvidia-driver
2482 [3] From the bootblocks, boot -s, and then do
2486 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed
2487 cd src # full path to source
2488 adjkerntz -i # if CMOS is wall time
2489 Also, when doing a major release upgrade, it is required that you boot
2490 into single user mode to do the installworld.
2492 [4] Note: This step is non-optional. Failure to do this step
2493 can result in a significant reduction in the functionality of the
2494 system. Attempting to do it by hand is not recommended and those
2495 that pursue this avenue should read this file carefully, as well
2496 as the archives of freebsd-current and freebsd-hackers mailing lists
2497 for potential gotchas. The -U option is also useful to consider.
2498 See mergemaster(8) for more information.
2500 [5] Usually this step is a no-op. However, from time to time
2501 you may need to do this if you get unknown user in the following
2502 step. It never hurts to do it all the time. You may need to
2503 install a new mergemaster (cd src/usr.sbin/mergemaster && make
2504 install) after the buildworld before this step if you last updated
2505 from current before 20130425 or from -stable before 20130430.
2507 [6] This only deletes old files and directories. Old libraries
2508 can be deleted by "make delete-old-libs", but you have to make
2509 sure that no program is using those libraries anymore.
2511 [8] The new kernel must be able to run existing binaries used by an
2512 installworld. When upgrading across major versions, the new kernel's
2513 configuration must include the correct COMPAT_FREEBSD<n> option for
2514 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure
2515 to do so may leave you with a system that is hard to boot to recover. A
2516 GENERIC kernel will include suitable compatibility options to run
2517 binaries from older branches. Note that the ability to run binaries
2518 from unsupported branches is not guaranteed.
2520 Make sure that you merge any new devices from GENERIC since the
2521 last time you updated your kernel config file. Options also
2522 change over time, so you may need to adjust your custom kernels
2525 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2526 "?=" instead of the "=" assignment operator, so that buildworld can
2527 override the CPUTYPE if it needs to.
2529 MAKEOBJDIRPREFIX must be defined in an environment variable, and
2530 not on the command line, or in /etc/make.conf. buildworld will
2531 warn if it is improperly defined.
2534 This file contains a list, in reverse chronological order, of major
2535 breakages in tracking -current. It is not guaranteed to be a complete
2536 list of such breakages, and only contains entries since September 23, 2011.
2537 If you need to see UPDATING entries from before that date, you will need
2538 to fetch an UPDATING file from an older FreeBSD release.
