99 For 64-bit architectures the base system is now built with Position
100 Independent Executable (PIE) support enabled by default. It may be
101 disabled using the WITHOUT_PIE knob. A clean build is required.
104 The macros provided for the manipulation of CPU sets (e.g. CPU_AND)
105 have been modified to take 2 source arguments instead of only 1.
106 Externally maintained sources that use these macros will have to
107 be adapted. The FreeBSD version has been bumped to 1300524 to
111 Commit 18f5b477ee66 adds two arguments to VOP_ALLOCATE().
112 Normally changes to VOP calls are not MFC'd, but a
113 discussion on freebsd-current@ seemed to agree that
114 it was acceptable in this case, to fix the NFSv4.2 server.
115 Any out of source tree file system with a custom
116 VOP_ALLOCATE() call will need to be modified.
117 Bump __FreeBSD_version to 1300523 since the NFS modules need
118 to be rebuilt from sources.
121 Commit 6e8e261f0d4e changed the internal KAPI between the NFS
122 modules. As such, all the modules must be rebuilt from sources.
123 __FreeBSD_version has been bumped to 1300522.
126 Bump __FreeBSD_version to 1300521 after merging LinuxKPI and
127 net80211 changes in order to support building various wireless
128 drivers. This is to help other external consumers of LinuxKPI
129 and net80211 to deal accordingly.
132 Commit a599f9f7620b deleted the variable called nfs_maxcopyrange
133 from nfscommon.ko, since it no longer needs to be global. As such,
134 the other nfs modules must be rebuilt from up to date sources.
135 Bump __FreeBSD_version to 1300516 for this.
138 As of commit 622809b0868f OpenSSL no longer enables kernel TLS
139 by default. Users can enable kernel TLS via the "KTLS" SSL
140 option. This can be enabled globally by using a custom
141 OpenSSL config file via OPENSSL_CONF or via an
142 application-specific configuration option for applications
143 which permit setting SSL options via SSL_CONF_cmd(3).
146 Commits 9fb6e613373c and 9ec7dbf46b0a both changed the internal
147 KAPI between the NFS modules. Bump __FreeBSD_version to 1300514.
148 All NFS modules must be rebuilt from sources.
151 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl.
152 As of be70c7a50d32 it is no longer used by userspace, but it does mean
153 users may not be able to enumerate pf states if they update the kernel
154 past c021ff986e2b without first updating userspace past be70c7a50d32.
157 Bump __FreeBSD_version to 1300512 after merging LinuxKPI, OFED,
158 net80211, and driver changes in order to support building
159 Intel wireless iwlwifi drivers. This is especially needed for
160 drm-kmod which needs updates after this.
163 The 20210707 awk update brought in a change in behavior. This has
164 been corrected as of d4d252c49976. Between these dates, if you
165 installed a new awk binary, you may not be able to build a new
166 kernel because the change in behavior affected the genoffset
167 script used to build the kernel. If you did update, the fix is
168 to update your sources past the above hash and do
171 % sudo -E make install
172 to enable building kernels again.
175 Commit 8a04edfdcbd2 changes the default minor version
176 used for NFSv4 mounts to the highest minor version supported
177 by the NFSv4 server. This default can be overridden by using
178 the "minorversion" mount option.
179 The consensus of a discussion on freebsd-current@ indicated
180 that this would be acceptable to do and would not be considered
184 awk has been updated to the latest one-true-awk version 20210215.
185 This contains a number of minor bug fixes.
188 Commit ca179c4d74f2/632e3f2f3a66 changed the package in which
189 the OpenSSL libraries and utilities are packaged.
190 It is recommended for pkgbase user to do:
191 pkg install -f FreeBSD-openssl
192 before pkg upgrade otherwise some dependencies might not be met
193 and pkg will stop working as libssl will not be present anymore
197 Commit 841006678745 changed the internal KAPI between the krpc
198 and nfsd modules. As such, they must both be rebuilt from
200 __FreeBSD_version is bumped to 1300510.
203 Commit 272f39942254 changed the internal KAPI between the
204 nscl.ko and nfscommon.ko modules, so they both need to be
205 rebuilt from sources.
208 Commit 5a45802b3c8c changed the internal KAPI between
209 the krpc and NFS. As such, the krpc, nfscommon and
210 nfscl modules must all be rebuilt from sources.
211 Without this patch, NFSv4.1/4.2 mounts should not
212 be done with the nfscbd(8) daemon running, to avoid
213 needing a working back channel for server->client RPCs.
216 Various LinuxKPI functionality was added which conflicts with DRM.
217 Please update your drm-kmod port to after the __FreeBSD_verison 1300139
221 The stable/13 branch has been created from main.
224 PC Card attachments for all devices have been removed. In the case of
225 wi and cmx, the entire drivers were removed because they were only
226 PC Card devices. FreeBSD_version 1300134 should be used for this
227 since it was bumped so recently.
230 Transport-independent parts of HID support have been split off the USB
231 code in to separate subsystem. Kernel configs which include one of
232 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
233 be updated with adding of "device hid" line.
236 ncurses installation has been modified to only keep the widechar
237 enabled version. Incremental build is broken for that change, so it
238 requires a clean build.
241 The FreeBSD project has migrated from Subversion to Git. Temporary
242 instructions can be found at
243 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
244 and other documents in that repo.
247 The services database has been updated to cover more of the basic
248 services expected in a modern system. The database is big enough
249 that it will cause issues in mergemaster in Releases previous to
250 12.2 and 11.3, or in very old current systems from before r358154.
253 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
254 may be installed from ports or packages.
257 ping6 has been merged into ping. It can now be called as "ping -6".
258 See ping(8) for details.
261 Default value of net.add_addr_allfibs has been changed to 0.
262 If you have multi-fib configuration and rely on existence of all
263 interface routes in every fib, you need to set the above sysctl to 1.
265 The internal pre-processor in the calendar(1) program has been
266 extended to support more C pre-processor commands (e.g. #ifdef, #else,
267 and #undef) and to detect unbalanced conditional statements.
268 Error messages have been extended to include the filename and line
269 number if processing stops to help fixing malformed data files.
272 All the data files for the calendar(1) program, except calendar.freebsd,
273 have been moved to the deskutils/calendar-data port, much like the
274 jewish calendar entries were moved to deskutils/hebcal years ago. After
275 make delete-old-files, you need to install it to retain full
276 functionality. calendar(1) will issue a reminder for files it can't
280 LINT files are no longer generated. We now include the relevant NOTES
281 files. Note: This may cause conflicts with updating in some cases.
282 find sys -name LINT\* -delete
283 is suggested across this commit to remove the generated LINT files.
285 If you have tried to update with generated files there, the svn
286 command you want to un-auger the tree is
289 and then do the above find from the top level. Substitute 'amd64'
290 above with where the error message indicates a conflict.
293 OpenZFS support has been integrated. Do not upgrade root pools until
294 the loader is updated to support zstd. Furthermore, we caution against
295 'zpool upgrade' for the next few weeks. The change should be transparent
296 unless you want to use new features.
298 Not all "NO_CLEAN" build scenarios work across these changes. Many
299 scenarios have been tested and fixed, but rebuilding kernels without
300 rebuilding world may fail.
302 The ZFS cache file has moved from /boot to /etc to match the OpenZFS
303 upstream default. A fallback to /boot has been added for mountroot.
305 Pool auto import behavior at boot has been moved from the kernel module
306 to an explicit "zpool import -a" in one of the rc scripts enabled by
307 zfs_enable=YES. This means your non-root zpools won't auto import until
308 you upgrade your /etc/rc.d files.
311 The resume code now notifies devd with the 'kernel' system
312 rather than the old 'kern' subsystem to be consistent with
313 other use. The old notification will be created as well, but
314 will be removed prior to FreeBSD 14.0.
317 r362275 changed the internal API between the kernel RPC and the
318 NFS modules. As such, all the modules must be recompiled from
322 r364330 modified the internal API used between the NFS modules.
323 As such, all the NFS modules must be re-compiled from sources.
326 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
327 been upgraded to 11.0.0. Please see the 20141231 entry below for
328 information about prerequisites and upgrading, if you are not already
329 using clang 3.5.0 or higher.
332 r364092 modified the internal ABI used between the kernel NFS
333 modules. As such, all of these modules need to be rebuilt
334 from sources, so a version bump was done.
337 Makefile.inc has been updated to work around the issue documented in
338 20200729. It was a case where the optimization of using symbolic links
339 to point to binaries created a situation where we'd run new binaries
340 with old libraries starting midway through the installworld process.
343 r363679 has redefined some undefined behavior in regcomp(3); notably,
344 extraneous escapes of most ordinary characters will no longer be
345 accepted. An exp-run has identified all of the problems with this in
346 ports, but other non-ports software may need extra escapes removed to
347 continue to function.
349 Because of this change, installworld may encounter the following error
350 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
351 you do not halt installworld. Instead, let it run to completion (whether
352 successful or not) and run installworld once more.
355 A new implementation of bc and dc has been imported in r362681. This
356 implementation corrects non-conformant behavior of the previous bc
357 and adds GNU bc compatible options. It offers a number of extensions,
358 is much faster on large values, and has support for message catalogs
359 (a number of languages are already supported, contributions of further
360 languages welcome). The option WITHOUT_GH_BC can be used to build the
361 world with the previous versions of bc and dc.
364 r362639 changed the internal API used between the NFS kernel modules.
365 As such, they all need to be rebuilt from sources.
368 r362158 changed the arguments for VFS_CHECKEXP(). As such, any
369 out of tree file systems need to be modified and rebuilt.
370 Also, any file systems that are modules must be rebuilt.
373 read(2) of a directory fd is now rejected by default. root may
374 re-enable it for system root only on non-ZFS filesystems with the
375 security.bsd.allow_read_dir sysctl(8) MIB if
376 security.bsd.suser_enabled=1.
378 It may be advised to setup aliases for grep to default to `-d skip` if
379 commonly non-recursively grepping a list that includes directories and
380 the potential for the resulting stderr output is not tolerable. Example
381 aliases are now installed, commented out, in /root/.cshrc and
385 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
386 been upgraded to 10.0.1. Please see the 20141231 entry below for
387 information about prerequisites and upgrading, if you are not already
388 using clang 3.5.0 or higher.
391 Support for obsolete compilers has been removed from the build system.
392 Clang 6 and GCC 6.4 are the minimum supported versions.
395 closefrom(2) has been moved under COMPAT12, and replaced in libc with a
396 stub that calls close_range(2). If using a custom kernel configuration,
397 you may want to ensure that the COMPAT_FREEBSD12 option is included, as
398 a slightly older -CURRENT userland and older FreeBSD userlands may not
399 be functional without closefrom(2).
402 Upstream DTS from Linux 5.6 was merged and they now have the SID
403 and THS (Secure ID controller and THermal Sensor) node present.
404 The DTB overlays have now been removed from the tree for the H3/H5 and
405 A64 SoCs and the aw_sid and aw_thermal driver have been updated to
406 deal with upstream DTS. If you are using those overlays you need to
407 remove them from loader.conf and update the DTBs on the FAT partition.
410 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
411 been upgraded to 10.0.0. Please see the 20141231 entry below for
412 information about prerequisites and upgrading, if you are not already
413 using clang 3.5.0 or higher.
416 The amd(8) automount daemon has been removed from the source tree.
417 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
418 amd is still available in the sysutils/am-utils port.
421 Removed brooktree driver (bktr.4) from the tree.
424 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
425 compiler in usr.bin/dtc is used on all architectures which use dtc, and
426 the GPL dtc is available (if needed) from the sysutils/dtc port.
429 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
430 is used by all supported CPU architectures.
433 GCC 4.2.1 has been removed from the tree. The WITH_GCC,
434 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
435 Users who wish to build FreeBSD with GCC must use the external toolchain
439 ncurses has been updated to a newer version (6.2-20200215). Given the ABI
440 has changed, users will have to rebuild all the ports that are linked to
444 The size of struct vnet and the magic cookie have changed.
445 Users need to recompile libkvm and all modules using VIMAGE
446 together with their new kernel.
449 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
450 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
451 your Makefiles and scripts to define MK_<var>=no instead as required.
453 One exception to this is that program or library Makefiles should
454 define MAN to empty rather than setting MK_MAN=no.
457 Clang/LLVM is now the default compiler and LLD the default
461 make universe no longer uses GCC 4.2.1 on any architectures.
462 Architectures not supported by in-tree Clang/LLVM require an
463 external toolchain package.
466 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
467 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
468 options default to off for all supported CPU architectures. As a
469 short-term transition aid they may be enabled via WITH_* options.
470 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
473 Support for armv5 has been disconnected and is being removed. The
474 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
475 You must now use a MACHINE_ARCH of armv6 or armv7. The default
476 MACHINE_ARCH for MACHINE=arm is now armv7.
479 Clang/LLVM is now the default compiler for all powerpc architectures.
480 LLD is now the default linker for powerpc64. The change for powerpc64
481 also includes a change to the ELFv2 ABI, incompatible with the existing
485 Kernel-loadable random(4) modules are no longer unloadable.
488 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
489 been upgraded to 9.0.1. Please see the 20141231 entry below for
490 information about prerequisites and upgrading, if you are not already
491 using clang 3.5.0 or higher.
494 r355677 has modified the internal interface used between the
495 NFS modules in the kernel. As such, they must all be upgraded
496 simultaneously. I will do a version bump for this.
499 The root certificates of the Mozilla CA Certificate Store have been
500 imported into the base system and can be managed with the certctl(8)
501 utility. If you have installed the security/ca_root_nss port or package
502 with the ETCSYMLINK option (the default), be advised that there may be
503 differences between those included in the port and those included in
504 base due to differences in nss branch used as well as general update
505 frequency. Note also that certctl(8) cannot manage certs in the
506 format used by the security/ca_root_nss port.
509 The amd(8) automount daemon has been disabled by default, and will be
510 removed in the future. As of FreeBSD 10.1 the autofs(5) is available
514 The nctgpio and wbwd drivers have been moved to the superio bus.
515 If you have one of these drivers in a kernel configuration, then
516 you should add device superio to it. If you use one of these drivers
517 as a module and you compile a custom set of modules, then you should
518 add superio to the set.
521 KPIs for network drivers to access interface addresses have changed.
522 Users need to recompile NIC driver modules together with kernel.
525 The net.link.tap.user_open sysctl no longer prevents user opening of
526 already created /dev/tapNN devices. Access is still controlled by
527 node permissions, just like tun devices. The net.link.tap.user_open
528 sysctl is now used only to allow users to perform devfs cloning of
529 tap devices, and the subsequent open may not succeed if the user is not
530 in the appropriate group. This sysctl may be deprecated/removed
531 completely in the future.
534 mips, powerpc, and sparc64 are no longer built as part of
535 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
536 not defined, mips, powerpc, and sparc64 builds will look for
537 the xtoolchain binaries and if installed use them for universe
538 builds. As llvm 9.0 becomes vetted for these architectures, they
539 will be removed from the list.
542 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
543 been upgraded to 9.0.0. Please see the 20141231 entry below for
544 information about prerequisites and upgrading, if you are not already
545 using clang 3.5.0 or higher.
548 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
549 GENERIC. They are available as modules and can be loaded by adding
550 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
551 hptnr_load="YES", or hptrr_load="YES", respectively.
554 ntpd no longer by default locks its pages in memory, allowing them
555 to be paged out by the kernel. Use rlimit memlock to restore
556 historic BSD behaviour. For example, add "rlimit memlock 32"
557 to ntp.conf to lock up to 32 MB of ntpd address space in memory.
560 Several of ping6's options have been renamed for better consistency
561 with ping. If you use any of -ARWXaghmrtwx, you must update your
562 scripts. See ping6(8) for details.
565 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
566 and the "-o sync_unmount" and "-o init_backgrounded" mount options have
567 been removed from mount_fusefs(8). You can safely remove them from
568 your scripts, because they had no effect.
570 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
571 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
572 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
573 sysctls have been removed. If you felt the need to set any of them to
574 a non-default value, please tell asomers@FreeBSD.org why.
577 Default permissions on the /var/account/acct file (and copies of it
578 rotated by periodic daily scripts) are changed from 0644 to 0640
579 because the file contains sensitive information that should not be
580 world-readable. If the /var/account directory must be created by
581 rc.d/accounting, the mode used is now 0750. Admins who use the
582 accounting feature are encouraged to change the mode of an existing
583 /var/account directory to 0750 or 0700.
586 Entropy collection and the /dev/random device are no longer optional
587 components. The "device random" option has been removed.
588 Implementations of distilling algorithms can still be made loadable
589 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
592 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
593 been upgraded to 8.0.1. Please see the 20141231 entry below for
594 information about prerequisites and upgrading, if you are not already
595 using clang 3.5.0 or higher.
598 A fix was applied to i386 kernel modules to avoid panics with
599 dpcpu or vnet. Users need to recompile i386 kernel modules
600 having pcpu or vnet sections or they will refuse to load.
603 User-wired pages now have their own counter,
604 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
605 to vm.max_user_wired and changed from an unsigned int to an unsigned
606 long. bhyve VMs wired with the -S are now subject to the user
607 wiring limit; the vm.max_user_wired sysctl may need to be tuned to
608 avoid running into the limit.
611 The IPSEC option has been removed from GENERIC. Users requiring
612 ipsec(4) must now load the ipsec(4) kernel module.
615 The tap(4) driver has been folded into tun(4), and the module has been
616 renamed to tuntap. You should update any kld_list="if_tap" or
617 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
618 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
619 module instead, and "device tap" or "device tun" entries in kernel
620 config files to select the tuntap device instead.
623 The following knobs have been added related to tradeoffs between
624 safe use of the random device and availability in the absence of
627 kern.random.initial_seeding.bypass_before_seeding: tunable; set
628 non-zero to bypass the random device prior to seeding, or zero to
629 block random requests until the random device is initially seeded.
630 For now, set to 1 (unsafe) by default to restore pre-r346250 boot
631 availability properties.
633 kern.random.initial_seeding.read_random_bypassed_before_seeding:
634 read-only diagnostic sysctl that is set when bypass is enabled and
635 read_random(9) is bypassed, to enable programmatic handling of this
636 initial condition, if desired.
638 kern.random.initial_seeding.arc4random_bypassed_before_seeding:
639 Similar to the above, but for for arc4random(9) initial seeding.
641 kern.random.initial_seeding.disable_bypass_warnings: tunable; set
642 non-zero to disable warnings in dmesg when the same conditions are
643 met as for the diagnostic sysctls above. Defaults to zero, i.e.,
644 produce warnings in dmesg when the conditions are met.
647 The loadable random module KPI has changed; the random_infra_init()
648 routine now requires a 3rd function pointer for a bool (*)(void)
649 method that returns true if the random device is seeded (and
650 therefore unblocked).
653 r345895 reverts r320698. This implies that an nfsuserd(8) daemon
654 built from head sources between r320757 (July 6, 2017) and
655 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
656 is added to the command line.
657 nfsuserd daemons built from head sources that are post-r338192 are
658 not affected and should continue to work.
661 The fuse(4) module has been renamed to fusefs(4) for consistency with
662 other filesystems. You should update any kld_load="fuse" entries in
663 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
664 "options FUSE" entries in kernel config files.
667 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
668 8.0.0. Please see the 20141231 entry below for information about
669 prerequisites and upgrading, if you are not already using clang 3.5.0
673 geom_uzip(4) depends on the new module xz. If geom_uzip is statically
674 compiled into your custom kernel, add 'device xz' statement to the
678 drm and drm2 have been removed from the tree. Please see
679 https://wiki.freebsd.org/Graphics for the latest information on
680 migrating to the drm ports.
683 Iflib is no longer unconditionally compiled into the kernel. Drivers
684 using iflib and statically compiled into the kernel, now require
685 the 'device iflib' config option. For the same drivers loaded as
686 modules on kernels not having 'device iflib', the iflib.ko module
687 is loaded automatically.
690 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
691 options no longer exist since r343219 and r343427 respectively;
692 nothing uses them, so they should be just removed from custom
696 r342635 changes the way efibootmgr(8) works by requiring users to add
697 the -b (bootnum) parameter for commands where the bootnum was previously
698 specified with each option. For example 'efibootmgr -B 0001' is now
699 'efibootmgr -B -b 0001'.
702 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
703 in the same as it is applied to NFSv2 and 3. This implies that NFSv4
704 servers that have vfs.nfsd.nfs_privport set will only allow mounts
705 from clients using a reserved port#. Since both the FreeBSD and Linux
706 NFSv4 clients use reserved port#s by default, this should not affect
710 The XLP config has been removed. We can't support 64-bit atomics in this
711 kernel because it is running in 32-bit mode. XLP users must transition
712 to running a 64-bit kernel (XLP64 or XLPN32).
714 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
715 the preferred emulator today and we don't need two different ones.
717 The old sibyte / swarm / Broadcom BCM1250 support has been
718 removed from the mips port.
721 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
722 7.0.1. Please see the 20141231 entry below for information about
723 prerequisites and upgrading, if you are not already using clang 3.5.0
727 Remove the timed and netdate programs from the base tree. Setting
728 the time with these daemons has been obsolete for over a decade.
731 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
732 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
733 it produces broken binaries when ifuncs are in use. Users needing
734 GNU ld should install the binutils port or package.
737 The BSD crtbegin and crtend code has been enabled by default. It has
738 had extensive testing on amd64, arm64, and i386. It can be disabled
739 by building a world with -DWITHOUT_BSD_CRTBEGIN.
742 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
743 has been converted to a port (misc/ctm) and will be removed from
744 FreeBSD-13. It is available as a package (ctm) for all supported
748 The default newsyslog.conf(5) file has been changed to only include
749 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
750 the filenames end in '.conf' and do not begin with a '.'.
752 You should check the configuration files in these two directories match
753 this naming convention. You can verify which configuration files are
754 being included using the command:
758 Ports for the DRM modules have been simplified. Now, amd64 users should
759 just install the drm-kmod port. All others should install
762 Graphics hardware that's newer than about 2010 usually works with
763 drm-kmod. For hardware older than 2013, however, some users will need
764 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
765 than 2008 usually only works in drm-legacy-kmod. The graphics team can
766 only commit to hardware made since 2013 due to the complexity of the
767 market and difficulty to test all the older cards effectively. If you
768 have hardware supported by drm-kmod, you are strongly encouraged to use
769 that as you will get better support.
771 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
772 elsewhere, the drm and drm2 modules will be eliminated from the src base
773 soon (with a limited exception for arm). Please update to the package
774 asap and report any issues to x11@freebsd.org.
776 Generally, anybody using the drm*-kmod packages should add
777 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
778 cross-threading surprises, especially with automatic driver
779 loading from X11 startup. These will become the defaults in 13-current
783 The ixlv(4) driver has been renamed to iavf(4). As a consequence,
784 custom kernel and module loading configuration files must be updated
785 accordingly. Moreover, interfaces previous presented as ixlvN to the
786 system are now exposed as iavfN and network configuration files must
787 be adjusted as necessary.
790 OpenSSL has been updated to version 1.1.1. This update included
791 additional various API changes throughout the base system. It is
792 important to rebuild third-party software after upgrading. The value
793 of __FreeBSD_version has been bumped accordingly.
796 The legacy DRM modules and drivers have now been added to the loader's
797 module blacklist, in favor of loading them with kld_list in rc.conf(5).
798 The module blacklist may be overridden with the loader.conf(5)
799 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
803 The cam(4) based nda(4) driver will be used over nvd(4) by default on
804 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
805 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
806 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
810 Reproducible build mode is now on by default, in preparation for
811 FreeBSD 12.0. This eliminates build metadata such as the user,
812 host, and time from the kernel (and uname), unless the working tree
813 corresponds to a modified checkout from a version control system.
814 The previous behavior can be obtained by setting the /etc/src.conf
815 knob WITHOUT_REPRODUCIBLE_BUILD.
818 The Yarrow CSPRNG has been removed from the kernel as it has not been
819 supported by its designers since at least 2003. Fortuna has been the
820 default since FreeBSD-11.
823 devctl freeze/thaw have gone into the tree, the rc scripts have been
824 updated to use them and devmatch has been changed. You should update
825 kernel, userland and rc scripts all at the same time.
828 The default interpreter has been switched from 4th to Lua.
829 LOADER_DEFAULT_INTERP, documented in build(7), will override the default
830 interpreter. If you have custom FORTH code you will need to set
831 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
832 src.conf for the build. This will create default hard links between
833 loader and loader_4th instead of loader and loader_lua, the new default.
834 If you are using UEFI it will create the proper hard link to loader.efi.
836 bhyve uses userboot.so. It remains 4th-only until some issues are solved
837 regarding coexisting with multiple versions of FreeBSD are resolved.
840 ls(1) now respects the COLORTERM environment variable used in other
841 systems and software to indicate that a colored terminal is both
842 supported and desired. If ls(1) is suddenly emitting colors, they may
843 be disabled again by either removing the unwanted COLORTERM from your
844 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
845 may not be observed in a future release.
848 The default pager for most commands has been changed to "less". To
849 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
853 The jedec_ts(4) driver has been removed. A superset of its functionality
854 is available in the jedec_dimm(4) driver, and the manpage for that
855 driver includes migration instructions. If you have "device jedec_ts"
856 in your kernel configuration file, it must be removed.
859 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
860 This should have no effect if the kernel is booted via BIOS/legacy boot.
861 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
862 has a buggy firmware that prevents a successful boot due to use of
866 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
867 support has been removed from the tree. These ports were
868 obsolete and/or known to be broken for many years.
871 loader.efi has been augmented to participate more fully in the
872 UEFI boot manager protocol. loader.efi will now look at the
873 BootXXXX environment variable to determine if a specific kernel
874 or root partition was specified. XXXX is derived from BootCurrent.
875 efibootmgr(8) manages these standard UEFI variables.
878 zfsloader's functionality has now been folded into loader.
879 zfsloader is no longer necessary once you've updated your
880 boot blocks. For a transition period, we will install a
881 hardlink for zfsloader to loader to allow a smooth transition
882 until the boot blocks can be updated (hard link because old
883 zfs boot blocks don't understand symlinks).
886 ARM64 now have efifb support, if you want to have serial console
887 on your arm64 board when an screen is connected and the bootloader
888 setup a frame buffer for us to use, just add :
892 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
893 an screen connected as the firmware will setup a frame buffer are that
894 u-boot will expose as an EFI frame buffer.
897 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
898 or take steps to update /etc/passwd before doing installworld on
899 existing systems. Do not skip the "mergemaster -Fp" step before
900 installworld, as described in the update procedures near the bottom
901 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
902 if the new mac_ntpd(4) policy is available, unless ntpd_flags or
903 the ntp config file contain options that change file/dir locations.
904 When such options (e.g., "statsdir" or "crypto") are used, ntpd can
905 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
906 taking steps to ensure that all required files/dirs are accessible
910 Big endian arm support has been removed.
913 The static environment setup in kernel configs is no longer mutually
914 exclusive with the loader(8) environment by default. In order to
915 restore the previous default behavior of disabling the loader(8)
916 environment if a static environment is present, you must specify
917 loader_env.disabled=1 in the static environment.
920 The ABI of syscalls used by management tools like sockstat and
921 netstat has been broken to allow 32-bit binaries to work on
922 64-bit kernels without modification. These programs will need
923 to match the kernel in order to function. External programs may
924 require minor modifications to accommodate a change of type in
925 structures from pointers to 64-bit virtual addresses.
928 On i386 and amd64 atomics are now inlined. Out of tree modules using
929 atomics will need to be rebuilt.
932 The '%I' format in the kern.corefile sysctl limits the number of
933 core files that a process can generate to the number stored in the
934 debug.ncores sysctl. The '%I' format is replaced by the single digit
935 index. Previously, if all indexes were taken the kernel would overwrite
936 only a core file with the highest index in a filename.
937 Currently the system will create a new core file if there is a free
938 index or if all slots are taken it will overwrite the oldest one.
941 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
942 6.0.1. Please see the 20141231 entry below for information about
943 prerequisites and upgrading, if you are not already using clang 3.5.0
947 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
948 needed to be changed to work with it. This change was made with r335763
949 and requires a mergemaster / etcupdate / etc to update the installed
953 r334930 changed the interface between the NFS modules, so they all
954 need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
957 As of r334391 lld is the default amd64 system linker; it is installed
958 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
962 The kernel / userland interface for devinfo changed, so you'll
963 need a new kernel and userland as a pair for it to work (rebuilding
964 lib/libdevinfo is all that's required). devinfo and devmatch will
965 not work, but everything else will when there's a mismatch.
968 The on-disk format for hwpmc callchain records has changed to include
969 threadid corresponding to a given record. This changes the field offsets
970 and thus requires that libpmcstat be rebuilt before using a kernel
974 The vxge(4) driver has been removed. This driver was introduced into
975 HEAD one week before the Exar left the Ethernet market and is not
976 known to be used. If you have device vxge in your kernel config file
980 The amd64 kernel now requires a ld that supports ifunc to produce a
981 working kernel, either lld or a newer binutils. lld is built by default
982 on amd64, and the 'buildkernel' target uses it automatically. However,
983 it is not the default linker, so building the kernel the traditional
984 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
985 binutils port/package). lld will soon be default, and this requirement
988 NOTE: As of r334391 lld is the default system linker on amd64, and no
989 workaround is necessary.
992 The nxge(4) driver has been removed. This driver was for PCI-X 10g
993 cards made by s2io/Neterion. The company was acquired by Exar and
994 no longer sells or supports Ethernet products. If you have device
995 nxge in your kernel config file it must be removed.
998 The tz database (tzdb) has been updated to 2018e. This version more
999 correctly models time stamps in time zones with negative DST such as
1000 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
1001 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
1002 time zone abbreviations and the tm_isdst flag.
1005 The ixgb(4) driver has been removed. This driver was for an early and
1006 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
1007 quickly shifted to the long lived ixgbe family. If you have device
1008 ixgb in your kernel config file it must be removed.
1011 The lmc(4) driver has been removed. This was a WAN interface
1012 card that was already reportedly rare in 2003, and had an ambiguous
1013 license. If you have device lmc in your kernel config file it must
1017 Support for Arcnet networks has been removed. If you have device
1018 arcnet or device cm in your kernel config file they must be
1022 Support for FDDI networks has been removed. If you have device
1023 fddi or device fpa in your kernel config file they must be
1027 In addition to supporting RFC 3164 formatted messages, the
1028 syslogd(8) service is now capable of parsing RFC 5424 formatted
1029 log messages. The main benefit of using RFC 5424 is that clients
1030 may now send log messages with timestamps containing year numbers,
1031 microseconds and time zone offsets.
1033 Similarly, the syslog(3) C library function has been altered to
1034 send RFC 5424 formatted messages to the local system logging
1035 daemon. On systems using syslogd(8), this change should have no
1036 negative impact, as long as syslogd(8) and the C library are
1037 updated at the same time. On systems using a different system
1038 logging daemon, it may be necessary to make configuration
1039 adjustments, depending on the software used.
1041 When using syslog-ng, add the 'syslog-protocol' flag to local
1042 input sources to enable parsing of RFC 5424 formatted messages:
1045 unix-dgram("/var/run/log" flags(syslog-protocol));
1048 When using rsyslog, disable the 'SysSock.UseSpecialParser' option
1049 of the 'imuxsock' module to let messages be processed by the
1050 regular RFC 3164/5424 parsing pipeline:
1052 module(load="imuxsock" SysSock.UseSpecialParser="off")
1054 Do note that these changes only affect communication between local
1055 applications and syslogd(8). The format that syslogd(8) uses to
1056 store messages on disk or forward messages to other systems
1057 remains unchanged. syslogd(8) still uses RFC 3164 for these
1058 purposes. Options to customize this behaviour will be added in the
1059 future. Utilities that process log files stored in /var/log are
1060 thus expected to continue to function as before.
1062 __FreeBSD_version has been incremented to 1200061 to denote this
1066 Support for token ring networks has been removed. If you
1067 have "device token" in your kernel config you should remove
1068 it. No device drivers supported token ring.
1071 makefs was modified to be able to tag ISO9660 El Torito boot catalog
1072 entries as EFI instead of overloading the i386 tag as done previously.
1073 The amd64 mkisoimages.sh script used to build amd64 ISO images for
1074 release was updated to use this. This may mean that makefs must be
1075 updated before "make cdrom" can be run in the release directory. This
1076 should be as simple as:
1078 $ cd $SRCDIR/usr.sbin/makefs
1079 $ make depend all install
1082 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
1083 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
1084 Co-existence for the transition period will come shortly. Booting is a
1085 complex environment and test coverage for Lua-enabled loaders has been
1086 thin, so it would be prudent to assume it might not work and make
1087 provisions for backup boot methods.
1090 devmatch functionality has been turned on in devd. It will automatically
1091 load drivers for unattached devices. This may cause unexpected drivers
1092 to be loaded. Please report any problems to current@ and
1096 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
1097 6.0.0. Please see the 20141231 entry below for information about
1098 prerequisites and upgrading, if you are not already using clang 3.5.0
1102 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
1103 This means it is used to link the kernel and userland libraries and
1104 executables, but is not yet installed as /usr/bin/ld by default.
1106 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
1107 WITHOUT_LLD_BOOTSTRAP=yes
1110 On i386, pmtimer has been removed. Its functionality has been folded
1111 into apm. It was a no-op on ACPI in current for a while now (but was
1112 still needed on i386 in FreeBSD 11 and earlier). Users may need to
1113 remove it from kernel config files.
1116 The use of RSS hash from the network card aka flowid has been
1117 disabled by default for lagg(4) as it's currently incompatible with
1118 the lacp and loadbalance protocols.
1120 This can be re-enabled by setting the following in loader.conf:
1121 net.link.lagg.default_use_flowid="1"
1124 The SW_WATCHDOG option is no longer necessary to enable the
1125 hardclock-based software watchdog if no hardware watchdog is
1126 configured. As before, SW_WATCHDOG will cause the software
1127 watchdog to be enabled even if a hardware watchdog is configured.
1130 r326887 fixes the issue described in the 20171214 UPDATING entry.
1131 r326888 flips the switch back to building GELI support always.
1134 r362593 broke ZFS + GELI support for reasons unknown. However,
1135 it also broke ZFS support generally, so GELI has been turned off
1136 by default as the lesser evil in r326857. If you boot off ZFS and/or
1137 GELI, it might not be a good time to update.
1140 PowerPC users must update loader(8) by rebuilding world before
1141 installing a new kernel, as the protocol connecting them has
1142 changed. Without the update, loader metadata will not be passed
1143 successfully to the kernel and users will have to enter their
1144 root partition at the kernel mountroot prompt to continue booting.
1145 Newer versions of loader can boot old kernels without issue.
1148 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to
1149 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
1150 to WITH/OUT_LOADER_GELI.
1153 The naive and non-compliant support of posix_fallocate(2) in ZFS
1154 has been removed as of r325320. The system call now returns EINVAL
1155 when used on a ZFS file. Although the new behavior complies with the
1156 standard, some consumers are not prepared to cope with it.
1157 One known victim is lld prior to r325420.
1160 Building in a FreeBSD src checkout will automatically create object
1161 directories now rather than store files in the current directory if
1162 'make obj' was not ran. Calling 'make obj' is no longer necessary.
1163 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
1164 /etc/src-env.conf (not /etc/src.conf), or passing the option in the
1168 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
1169 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
1170 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
1171 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
1172 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
1173 The UNIFIED_OBJDIR option is a transitional feature that will be
1174 removed for 12.0 release; please migrate to the new format for any
1175 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
1176 than hardcoding paths.
1179 The native-xtools target no longer installs the files by default to the
1180 OBJDIR. Use the native-xtools-install target with a DESTDIR to install
1181 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin.
1184 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT
1185 options are changing from controlling the build if defined / undefined
1186 to controlling the build with explicit 'yes' or 'no' values. They will
1187 shift to WITH/WITHOUT options to match other options in the system.
1190 libstand has turned into a private library for sys/boot use only.
1191 It is no longer supported as a public interface outside of sys/boot.
1194 The arm port has split armv6 into armv6 and armv7. armv7 is now
1195 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system
1196 and are running a kernel from before r324363, you will need to add
1197 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build.
1200 When building multiple kernels using KERNCONF, non-existent KERNCONF
1201 files will produce an error and buildkernel will fail. Previously
1202 missing KERNCONF files silently failed giving no indication as to
1203 why, only to subsequently discover during installkernel that the
1204 desired kernel was never built in the first place.
1207 The default serial number format for CTL LUNs has changed. This will
1208 affect users who use /dev/diskid/* device nodes, or whose FibreChannel
1209 or iSCSI clients care about their LUNs' serial numbers. Users who
1210 require serial number stability should hardcode serial numbers in
1214 For 32-bit arm compiled for hard-float support, soft-floating point
1215 binaries now always get their shared libraries from
1216 LD_SOFT_LIBRARY_PATH (in the past, this was only used if
1217 /usr/libsoft also existed). Only users with a hard-float ld.so, but
1218 soft-float everything else should be affected.
1221 The geli password typed at boot is now hidden. To restore the previous
1222 behavior, see geli(8) for configuration options.
1225 Move PMTUD blackhole counters to TCPSTATS and remove them from bare
1226 sysctl values. Minor nit, but requires a rebuild of both world/kernel
1230 "make check" behavior (made in ^/head@r295380) has been changed to
1231 execute from a limited sandbox, as opposed to executing from
1235 - The "beforecheck" and "aftercheck" targets are now specified.
1236 - ${CHECKDIR} (added in commit noted above) has been removed.
1237 - Legacy behavior can be enabled by setting
1238 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment.
1240 If the limited sandbox mode is enabled, "make check" will execute
1241 "make distribution", then install, execute the tests, and clean up the
1242 sandbox if successful.
1244 The "make distribution" and "make install" targets are typically run as
1245 root to set appropriate permissions and ownership at installation time.
1246 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the
1247 environment if executing "make check" with limited sandbox mode using
1248 an unprivileged user.
1251 Since the switch to GPT disk labels, fsck for UFS/FFS has been
1252 unable to automatically find alternate superblocks. As of r322297,
1253 the information needed to find alternate superblocks has been
1254 moved to the end of the area reserved for the boot block.
1255 Filesystems created with a newfs of this vintage or later
1256 will create the recovery information. If you have a filesystem
1257 created prior to this change and wish to have a recovery block
1258 created for your filesystem, you can do so by running fsck in
1259 foreground mode (i.e., do not use the -p or -y options). As it
1260 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS''
1261 to which you should answer yes.
1264 As of r321665, an NFSv4 server configuration that services
1265 Kerberos mounts or clients that do not support the uid/gid in
1266 owner/owner_group string capability, must explicitly enable
1267 the nfsuserd daemon by adding nfsuserd_enable="YES" to the
1268 machine's /etc/rc.conf file.
1271 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0.
1272 Please see the 20141231 entry below for information about prerequisites
1273 and upgrading, if you are not already using clang 3.5.0 or higher.
1276 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the
1277 r-commands (rlogin, rsh, etc.) to be built with the base system.
1280 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is
1281 a very major ABI incompatible change, so users of FreeBSD/powerpc must
1282 be careful when performing source upgrades. It is best to run
1283 'make installworld' from an alternate root system, either a live
1284 CD/memory stick, or a temporary root partition. Additionally, all ports
1285 must be recompiled. powerpc64 is largely unaffected, except in the case
1286 of 32-bit compatibility. All 32-bit binaries will be affected.
1289 Forward compatibility for the "ino64" project have been committed. This
1290 will allow most new binaries to run on older kernels in a limited
1291 fashion. This prevents many of the common foot-shooting actions in the
1292 upgrade as well as the limited ability to roll back the kernel across
1293 the ino64 upgrade. Complicated use cases may not work properly, though
1294 enough simpler ones work to allow recovery in most situations.
1297 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC
1298 if you require the GPL compiler.
1301 The internal ABI used for communication between the NFS kernel modules
1302 was changed by r320085, so __FreeBSD_version was bumped to
1303 ensure all the NFS related modules are updated together.
1306 The ABI of struct event was changed by extending the data
1307 member to 64bit and adding ext fields. For upgrade, same
1308 precautions as for the entry 20170523 "ino64" must be
1312 The GNU roff toolchain has been removed from base. To render manpages
1313 which are not supported by mandoc(1), man(1) can fallback on GNU roff
1314 from ports (and recommends to install it).
1315 To render roff(7) documents, consider using GNU roff from ports or the
1316 heirloom doctools roff toolchain from ports via pkg install groff or
1317 via pkg install heirloom-doctools.
1320 The ath(4) and ath_hal(4) modules now build piecemeal to allow for
1321 smaller runtime footprint builds. This is useful for embedded systems
1322 which only require one chipset support.
1324 If you load it as a module, make sure this is in /boot/loader.conf:
1328 This will load the HAL, all chip/RF backends and if_ath_pci.
1329 If you have if_ath_pci in /boot/loader.conf, ensure it is after
1330 if_ath or it will not load any HAL chipset support.
1332 If you want to selectively load things (eg on ye cheape ARM/MIPS
1333 platforms where RAM is at a premium) you should:
1336 * load the chip modules in question
1337 * load ath_rate, ath_dfs
1339 * load if_ath_pci and/or if_ath_ahb depending upon your particular
1340 bus bind type - this is where probe/attach is done.
1342 For further comments/feedback, poke adrian@ .
1345 The "ino64" 64-bit inode project has been committed, which extends
1346 a number of types to 64 bits. Upgrading in place requires care and
1347 adherence to the documented upgrade procedure.
1349 If using a custom kernel configuration ensure that the
1350 COMPAT_FREEBSD11 option is included (as during the upgrade the
1351 system will be running the ino64 kernel with the existing world).
1353 For the safest in-place upgrade begin by removing previous build
1354 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full
1355 procedure documented below under the heading "To rebuild everything and
1356 install it on the current system." Specifically, a reboot is required
1357 after installing the new kernel before installing world. While an
1358 installworld normally works by accident from multiuser after rebooting
1359 the proper kernel, there are many cases where this will fail across this
1360 upgrade and installworld from single user is required.
1363 The NATM framework including the en(4), fatm(4), hatm(4), and
1364 patm(4) devices has been removed. Consumers should plan a
1365 migration before the end-of-life date for FreeBSD 11.
1368 GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1369 diff has not been implemented, if those are needed a newer version of
1370 GNU diff is available via the diffutils package under the gdiff name.
1373 As of r316810 for ipfilter, keep frags is no longer assumed when
1374 keep state is specified in a rule. r316810 aligns ipfilter with
1375 documentation in man pages separating keep frags from keep state.
1376 This allows keep state to be specified without forcing keep frags
1377 and allows keep frags to be specified independently of keep state.
1378 To maintain previous behaviour, also specify keep frags with
1379 keep state (as documented in ipf.conf.5).
1382 arm64 builds now use the base system LLD 4.0.0 linker by default,
1383 instead of requiring that the aarch64-binutils port or package be
1384 installed. To continue using aarch64-binutils, set
1385 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .
1388 The UDP optimization in entry 20160818 that added the sysctl
1389 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast
1390 packets will no longer be treated as L3 broadcast packets.
1393 Binds and sends to the loopback addresses, IPv6 and IPv4, will now
1394 use any explicitly assigned loopback address available in the jail
1395 instead of using the first assigned address of the jail.
1398 The ctl.ko module no longer implements the iSCSI target frontend:
1399 cfiscsi.ko does instead.
1401 If building cfiscsi.ko as a kernel module, the module can be loaded
1402 via one of the following methods:
1403 - `cfiscsi_load="YES"` in loader.conf(5).
1404 - Add `cfiscsi` to `$kld_list` in rc.conf(5).
1405 - ctladm(8)/ctld(8), when compiled with iSCSI support
1406 (`WITH_ISCSI=yes` in src.conf(5))
1408 Please see cfiscsi(4) for more details.
1411 The mmcsd.ko module now additionally depends on geom_flashmap.ko.
1412 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
1413 same source (previously, the dependency of mmcsd.ko on mmc.ko was
1414 missing, but mmcsd.ko now will refuse to load if it is incompatible
1418 The syntax of ipfw(8) named states was changed to avoid ambiguity.
1419 If you have used named states in the firewall rules, you need to modify
1420 them after installworld and before rebooting. Now named states must
1421 be prefixed with colon.
1424 The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1425 removed as the userland we provide cannot use them. The KMS version
1426 (sys/dev/drm2) supports the same hardware.
1429 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0.
1430 Please see the 20141231 entry below for information about prerequisites
1431 and upgrading, if you are not already using clang 3.5.0 or higher.
1434 The code that provides support for ZFS .zfs/ directory functionality
1435 has been reimplemented. It's not possible now to create a snapshot
1436 by mkdir under .zfs/snapshot/. That should be the only user visible
1440 EISA bus support has been removed. The WITH_EISA option is no longer
1444 MCA bus support has been removed.
1447 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1448 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.
1451 The EM_MULTIQUEUE kernel configuration option is deprecated now that
1452 the em(4) driver conforms to iflib specifications.
1455 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1456 IFLIB. If you have a custom kernel configuration that excludes em(4)
1457 but you use igb(4), you need to re-add em(4) to your custom
1461 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
1462 Please see the 20141231 entry below for information about prerequisites
1463 and upgrading, if you are not already using clang 3.5.0 or higher.
1466 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
1467 Please see the 20141231 entry below for information about prerequisites
1468 and upgrading, if you are not already using clang 3.5.0 or higher.
1471 The layout of the pmap structure has changed for powerpc to put the pmap
1472 statistics at the front for all CPU variations. libkvm(3) and all tools
1473 that link against it need to be recompiled.
1476 isl(4) and cyapa(4) drivers now require a new driver,
1477 chromebook_platform(4), to work properly on Chromebook-class hardware.
1478 On other types of hardware the drivers may need to be configured using
1479 device hints. Please see the corresponding manual pages for details.
1482 The urtwn(4) driver was merged into rtwn(4) and now consists of
1483 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
1485 Also, firmware for RTL8188CE was renamed due to possible name
1486 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
1489 GNU rcs has been removed from base. It is available as packages:
1490 - rcs: Latest GPLv3 GNU rcs version.
1491 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
1495 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1496 modules now requires that the kernel configuration contain the
1497 TCP_HHOOK option. (This option is included in the GENERIC kernel.)
1500 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
1501 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
1504 Relocatable object files with the extension of .So have been renamed
1505 to use an extension of .pico instead. The purpose of this change is
1506 to avoid a name clash with shared libraries on case-insensitive file
1507 systems. On those file systems, foo.So is the same file as foo.so.
1510 GNU rcs has been turned off by default. It can (temporarily) be built
1511 again by adding WITH_RCS knob in src.conf.
1512 Otherwise, GNU rcs is available from packages:
1513 - rcs: Latest GPLv3 GNU rcs version.
1514 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
1517 The backup_uses_rcs functionality has been removed from rc.subr.
1520 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
1521 two separate components, QUEUE_MACRO_DEBUG_TRACE and
1522 QUEUE_MACRO_DEBUG_TRASH. Define both for the original
1523 QUEUE_MACRO_DEBUG behavior.
1526 r304787 changed some ioctl interfaces between the iSCSI userspace
1527 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be
1528 rebuilt to work with new kernels. __FreeBSD_version has been bumped
1532 The UDP receive code has been updated to only treat incoming UDP
1533 packets that were addressed to an L2 broadcast address as L3
1534 broadcast packets. It is not expected that this will affect any
1535 standards-conforming UDP application. The new behaviour can be
1536 disabled by setting the sysctl net.inet.udp.require_l2_bcast to
1540 Remove the openbsd_poll system call.
1541 __FreeBSD_version has been bumped because of this.
1544 The stable/11 branch has been created from head@r302406.
1547 The libc stub for the pipe(2) system call has been replaced with
1548 a wrapper that calls the pipe2(2) system call and the pipe(2)
1549 system call is now only implemented by the kernels that include
1550 "options COMPAT_FREEBSD10" in their config file (this is the
1551 default). Users should ensure that this option is enabled in
1552 their kernel or upgrade userspace to r302092 before upgrading their
1556 CAM will now strip leading spaces from SCSI disks' serial numbers.
1557 This will affect users who create UFS filesystems on SCSI disks using
1558 those disk's diskid device nodes. For example, if /etc/fstab
1559 previously contained a line like
1560 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1561 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom
1562 transforms like gmirror may also be affected. ZFS users should
1566 The bitstring(3) API has been updated with new functionality and
1567 improved performance. But it is binary-incompatible with the old API.
1568 Objects built with the new headers may not be linked against objects
1569 built with the old headers.
1572 The brk and sbrk functions have been removed from libc on arm64.
1573 Binutils from ports has been updated to not link to these
1574 functions and should be updated to the latest version before
1575 installing a new libc.
1578 The armv6 port now defaults to hard float ABI. Limited support
1579 for running both hardfloat and soft float on the same system
1580 is available using the libraries installed with -DWITH_LIBSOFT.
1581 This has only been tested as an upgrade path for installworld
1582 and packages may fail or need manual intervention to run. New
1583 packages will be needed.
1585 To update an existing self-hosted armv6hf system, you must add
1586 TARGET_ARCH=armv6 on the make command line for both the build
1587 and the install steps.
1590 Kernel modules compiled outside of a kernel build now default to
1591 installing to /boot/modules instead of /boot/kernel. Many kernel
1592 modules built this way (such as those in ports) already overrode
1593 KMODDIR explicitly to install into /boot/modules. However,
1594 manually building and installing a module from /sys/modules will
1595 now install to /boot/modules instead of /boot/kernel.
1598 The CAM I/O scheduler has been committed to the kernel. There should be
1599 no user visible impact. This does enable NCQ Trim on ada SSDs. While the
1600 list of known rogues that claim support for this but actually corrupt
1601 data is believed to be complete, be on the lookout for data
1602 corruption. The known rogue list is believed to be complete:
1604 o Crucial MX100, M550 drives with MU01 firmware.
1605 o Micron M510 and M550 drives with MU01 firmware.
1606 o Micron M500 prior to MU07 firmware
1607 o Samsung 830, 840, and 850 all firmwares
1608 o FCCT M500 all firmwares
1610 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1611 with working NCQ TRIM. For Micron branded drives, see your sales rep for
1612 updated firmware. Black listed drives will work correctly because these
1613 drives work correctly so long as no NCQ TRIMs are sent to them. Given
1614 this list is the same as found in Linux, it's believed there are no
1615 other rogues in the market place. All other models from the above
1618 To be safe, if you are at all concerned, you can quirk each of your
1619 drives to prevent NCQ from being sent by setting:
1620 kern.cam.ada.X.quirks="0x2"
1621 in loader.conf. If the drive requires the 4k sector quirk, set the
1622 quirks entry to 0x3.
1625 The FAST_DEPEND build option has been removed and its functionality is
1626 now the one true way. The old mkdep(1) style of 'make depend' has
1627 been removed. See 20160311 for further details.
1630 Resource range types have grown from unsigned long to uintmax_t. All
1631 drivers, and anything using libdevinfo, need to be recompiled.
1634 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1635 builds. It no longer runs mkdep(1) during 'make depend', and the
1636 'make depend' stage can safely be skipped now as it is auto ran
1637 when building 'make all' and will generate all SRCS and DPSRCS before
1638 building anything else. Dependencies are gathered at compile time with
1639 -MF flags kept in separate .depend files per object file. Users should
1640 run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1641 stale .depend files.
1644 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1645 kernel modules. Therefore, if you load any kernel modules at boot time,
1646 please install the boot loaders after you install the kernel, but before
1650 make buildkernel KERNCONF=YOUR_KERNEL_HERE
1651 make installkernel KERNCONF=YOUR_KERNEL_HERE
1652 make -C sys/boot install
1653 <reboot in single user>
1655 Then follow the usual steps, described in the General Notes section,
1659 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please
1660 see the 20141231 entry below for information about prerequisites and
1661 upgrading, if you are not already using clang 3.5.0 or higher.
1664 The AIO subsystem is now a standard part of the kernel. The
1665 VFS_AIO kernel option and aio.ko kernel module have been removed.
1666 Due to stability concerns, asynchronous I/O requests are only
1667 permitted on sockets and raw disks by default. To enable
1668 asynchronous I/O requests on all file types, set the
1669 vfs.aio.enable_unsafe sysctl to a non-zero value.
1672 The ELF object manipulation tool objcopy is now provided by the
1673 ELF Tool Chain project rather than by GNU binutils. It should be a
1674 drop-in replacement, with the addition of arm64 support. The
1675 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1676 to obtain the GNU version if necessary.
1679 Building ZFS pools on top of zvols is prohibited by default. That
1680 feature has never worked safely; it's always been prone to deadlocks.
1681 Using a zvol as the backing store for a VM guest's virtual disk will
1682 still work, even if the guest is using ZFS. Legacy behavior can be
1683 restored by setting vfs.zfs.vol.recursive=1.
1686 The NONE and HPN patches has been removed from OpenSSH. They are
1687 still available in the security/openssh-portable port.
1690 With the addition of ypldap(8), a new _ypldap user is now required
1691 during installworld. "mergemaster -p" can be used to add the user
1692 prior to installworld, as documented in the handbook.
1695 The tftp loader (pxeboot) now uses the option root-path directive. As a
1696 consequence it no longer looks for a pxeboot.4th file on the tftp
1697 server. Instead it uses the regular /boot infrastructure as with the
1701 The code to start recording plug and play data into the modules has
1702 been committed. While the old tools will properly build a new kernel,
1703 a number of warnings about "unknown metadata record 4" will be produced
1704 for an older kldxref. To avoid such warnings, make sure to rebuild
1705 the kernel toolchain (or world). Make sure that you have r292078 or
1706 later when trying to build 292077 or later before rebuilding.
1709 Debug data files are now built by default with 'make buildworld' and
1710 installed with 'make installworld'. This facilitates debugging but
1711 requires more disk space both during the build and for the installed
1712 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1716 r291527 changed the internal interface between the nfsd.ko and
1717 nfscommon.ko modules. As such, they must both be upgraded to-gether.
1718 __FreeBSD_version has been bumped because of this.
1721 Add support for unicode collation strings leads to a change of
1722 order of files listed by ls(1) for example. To get back to the old
1723 behaviour, set LC_COLLATE environment variable to "C".
1725 Databases administrators will need to reindex their databases given
1726 collation results will be different.
1728 Due to a bug in install(1) it is recommended to remove the ancient
1729 locales before running make installworld.
1731 rm -rf /usr/share/locale/*
1734 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring
1735 libcrypto.so.7 or libssl.so.7 must be recompiled.
1738 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1739 Kernel modules isp_2400_multi and isp_2500_multi were removed and
1740 should be replaced with isp_2400 and isp_2500 modules respectively.
1743 The build previously allowed using 'make -n' to not recurse into
1744 sub-directories while showing what commands would be executed, and
1745 'make -n -n' to recursively show commands. Now 'make -n' will recurse
1746 and 'make -N' will not.
1749 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1750 and etcupdate will now use this file. A custom sendmail.cf is now
1751 updated via this mechanism rather than via installworld. If you had
1752 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1753 want to remove the exclusion or change it to "always install".
1754 /etc/mail/sendmail.cf is now managed the same way regardless of
1755 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using
1756 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1759 Compatibility shims for legacy ATA device names have been removed.
1760 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
1761 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
1762 environment variables, /dev/ad* and /dev/ar* symbolic links.
1765 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
1766 Please see the 20141231 entry below for information about prerequisites
1767 and upgrading, if you are not already using clang 3.5.0 or higher.
1770 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
1771 and renamed from .symbols to .debug. This reduces the size requirements
1772 on the boot partition or file system and provides consistency with
1773 userland debug files.
1775 When using the supported kernel installation method the
1776 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
1777 as is done with /boot/kernel.
1779 Developers wishing to maintain the historical behavior of installing
1780 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
1783 The wireless drivers had undergone changes that remove the 'parent
1784 interface' from the ifconfig -l output. The rc.d network scripts
1785 used to check presence of a parent interface in the list, so old
1786 scripts would fail to start wireless networking. Thus, etcupdate(3)
1787 or mergemaster(8) run is required after kernel update, to update your
1788 rc.d scripts in /etc.
1791 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
1792 These configurations are now automatically interpreted as
1793 'scrub fragment reassemble'.
1796 Kernel-loadable modules for the random(4) device are back. To use
1797 them, the kernel must have
1800 options RANDOM_LOADABLE
1802 kldload(8) can then be used to load random_fortuna.ko
1803 or random_yarrow.ko. Please note that due to the indirect
1804 function calls that the loadable modules need to provide,
1805 the build-in variants will be slightly more efficient.
1807 The random(4) kernel option RANDOM_DUMMY has been retired due to
1808 unpopularity. It was not all that useful anyway.
1811 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
1812 Control over building the ELF Tool Chain tools is now provided by
1813 the WITHOUT_TOOLCHAIN knob.
1816 The polarity of Pulse Per Second (PPS) capture events with the
1817 uart(4) driver has been corrected. Prior to this change the PPS
1818 "assert" event corresponded to the trailing edge of a positive PPS
1819 pulse and the "clear" event was the leading edge of the next pulse.
1821 As the width of a PPS pulse in a typical GPS receiver is on the
1822 order of 1 millisecond, most users will not notice any significant
1823 difference with this change.
1825 Anyone who has compensated for the historical polarity reversal by
1826 configuring a negative offset equal to the pulse width will need to
1827 remove that workaround.
1830 The default group assigned to /dev/dri entries has been changed
1831 from 'wheel' to 'video' with the id of '44'. If you want to have
1832 access to the dri devices please add yourself to the video group
1835 # pw groupmod video -m $USER
1838 The menu.rc and loader.rc files will now be replaced during
1839 upgrades. Please migrate local changes to menu.rc.local and
1840 loader.rc.local instead.
1843 GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1844 strings and strip have been removed. The src.conf(5) knob
1845 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1848 As ZFS requires more kernel stack pages than is the default on some
1849 architectures e.g. i386, it now warns if KSTACK_PAGES is less than
1850 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
1852 Please consider using 'options KSTACK_PAGES=X' where X is greater
1853 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
1856 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0
1857 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1858 default, i.e., they will not contain "::". For example, instead
1859 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet
1860 to have a more specific match, such as different map entries for
1861 IPv6:0:0 vs IPv6:0. This change requires that configuration
1862 data (including maps, files, classes, custom ruleset, etc.) must
1863 use the same format, so make certain such configuration data is
1864 upgrading. As a very simple check search for patterns like
1865 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old
1866 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1867 the cf option UseCompressedIPv6Addresses.
1870 The default kernel entropy-processing algorithm is now
1871 Fortuna, replacing Yarrow.
1873 Assuming you have 'device random' in your kernel config
1874 file, the configurations allow a kernel option to override
1875 this default. You may choose *ONE* of:
1877 options RANDOM_YARROW # Legacy /dev/random algorithm.
1878 options RANDOM_DUMMY # Blocking-only driver.
1880 If you have neither, you get Fortuna. For most people,
1881 read no further, Fortuna will give a /dev/random that works
1882 like it always used to, and the difference will be irrelevant.
1884 If you remove 'device random', you get *NO* kernel-processed
1885 entropy at all. This may be acceptable to folks building
1886 embedded systems, but has complications. Carry on reading,
1887 and it is assumed you know what you need.
1889 *PLEASE* read random(4) and random(9) if you are in the
1890 habit of tweaking kernel configs, and/or if you are a member
1891 of the embedded community, wanting specific and not-usual
1892 behaviour from your security subsystems.
1894 NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1895 random', you will NOT have a functioning /dev/random, and
1896 many cryptographic features will not work, including SSH.
1897 You may also find strange behaviour from the random(3) set
1898 of library functions, in particular sranddev(3), srandomdev(3)
1899 and arc4random(3). The reason for this is that the KERN_ARND
1900 sysctl only returns entropy if it thinks it has some to
1901 share, and with RANDOM_DUMMY or no 'device random' this
1905 An additional fix for the issue described in the 20150614 sendmail
1906 entry below has been committed in revision 284717.
1909 FreeBSD's old make (fmake) has been removed from the system. It is
1910 available as the devel/fmake port or via pkg install fmake.
1913 The fix for the issue described in the 20150614 sendmail entry
1914 below has been committed in revision 284436. The work
1915 around described in that entry is no longer needed unless the
1916 default setting is overridden by a confDH_PARAMETERS configuration
1917 setting of '5' or pointing to a 512 bit DH parameter file.
1920 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
1921 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
1922 and devel/kyua to version 0.20+ and adjust any calling code to work
1923 with Kyuafile and kyua.
1926 The import of openssl to address the FreeBSD-SA-15:10.openssl
1927 security advisory includes a change which rejects handshakes
1928 with DH parameters below 768 bits. sendmail releases prior
1929 to 8.15.2 (not yet released), defaulted to a 512 bit
1930 DH parameter setting for client connections. To work around
1931 this interoperability, sendmail can be configured to use a
1932 2048 bit DH parameter by:
1934 1. Edit /etc/mail/`hostname`.mc
1935 2. If a setting for confDH_PARAMETERS does not exist or
1936 exists and is set to a string beginning with '5',
1937 replace it with '2'.
1938 3. If a setting for confDH_PARAMETERS exists and is set to
1939 a file path, create a new file with:
1940 openssl dhparam -out /path/to/file 2048
1941 4. Rebuild the .cf file:
1942 cd /etc/mail/; make; make install
1943 5. Restart sendmail:
1944 cd /etc/mail/; make restart
1946 A sendmail patch is coming, at which time this file will be
1950 Generation of legacy formatted entries have been disabled by default
1951 in pwd_mkdb(8), as all base system consumers of the legacy formatted
1952 entries were converted to use the new format by default when the new,
1953 machine independent format have been added and supported since FreeBSD
1956 Please see the pwd_mkdb(8) manual page for further details.
1959 Clang and llvm have been upgraded to 3.6.1 release. Please see the
1960 20141231 entry below for information about prerequisites and upgrading,
1961 if you are not already using 3.5.0 or higher.
1964 TI platform code switched to using vendor DTS files and this update
1965 may break existing systems running on Beaglebone, Beaglebone Black,
1968 - dtb files should be regenerated/reinstalled. Filenames are the
1969 same but content is different now
1970 - GPIO addressing was changed, now each GPIO bank (32 pins per bank)
1971 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
1972 addressing scheme is now pin 25 on /dev/gpioc3.
1973 - Pandaboard: /etc/ttys should be updated, serial console device is
1974 now /dev/ttyu2, not /dev/ttyu0
1977 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
1978 If you need the GNU extension from groff soelim(1), install groff
1979 from package: pkg install groff, or via ports: textproc/groff.
1982 chmod, chflags, chown and chgrp now affect symlinks in -R mode as
1983 defined in symlink(7); previously symlinks were silently ignored.
1986 The const qualifier has been removed from iconv(3) to comply with
1987 POSIX. The ports tree is aware of this from r384038 onwards.
1990 Libraries specified by LIBADD in Makefiles must have a corresponding
1991 DPADD_<lib> variable to ensure correct dependencies. This is now
1992 enforced in src.libnames.mk.
1995 From legacy ata(4) driver was removed support for SATA controllers
1996 supported by more functional drivers ahci(4), siis(4) and mvs(4).
1997 Kernel modules ataahci and ataadaptec were removed completely,
1998 replaced by ahci and mvs modules respectively.
2001 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see
2002 the 20141231 entry below for information about prerequisites and
2003 upgrading, if you are not already using 3.5.0 or higher.
2006 The 32-bit PowerPC kernel has been changed to a position-independent
2007 executable. This can only be booted with a version of loader(8)
2008 newer than January 31, 2015, so make sure to update both world and
2009 kernel before rebooting.
2012 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
2013 but before r278950, the RNG was not seeded properly. Immediately
2014 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
2015 ssh keys or openssl keys) that were generated w/ a kernel from that
2016 range. This does not affect programs that directly used /dev/random
2017 or /dev/urandom. All userland uses of arc4random(3) are affected.
2020 The autofs(4) ABI was changed in order to restore binary compatibility
2021 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work
2022 with the new kernel.
2025 The powerpc64 kernel has been changed to a position-independent
2026 executable. This can only be booted with a new version of loader(8),
2027 so make sure to update both world and kernel before rebooting.
2030 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix
2031 only release, no new features have been added. Please see the 20141231
2032 entry below for information about prerequisites and upgrading, if you
2033 are not already using 3.5.0.
2036 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
2037 taken from the ELF Tool Chain project rather than GNU binutils. They
2038 should be drop-in replacements, with the addition of arm64 support.
2039 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
2040 binutils tools, if necessary. See 20150805 for updated information.
2043 The default Unbound configuration now enables remote control
2044 using a local socket. Users who have already enabled the
2045 local_unbound service should regenerate their configuration
2046 by running "service local_unbound setup" as root.
2049 The GNU texinfo and GNU info pages have been removed.
2050 To be able to view GNU info pages please install texinfo from ports.
2053 Clang, llvm and lldb have been upgraded to 3.5.0 release.
2055 As of this release, a prerequisite for building clang, llvm and lldb is
2056 a C++11 capable compiler and C++11 standard library. This means that to
2057 be able to successfully build the cross-tools stage of buildworld, with
2058 clang as the bootstrap compiler, your system compiler or cross compiler
2059 should either be clang 3.3 or later, or gcc 4.8 or later, and your
2060 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
2063 On any standard FreeBSD 10.x or 11.x installation, where clang and
2064 libc++ are on by default (that is, on x86 or arm), this should work out
2067 On 9.x installations where clang is enabled by default, e.g. on x86 and
2068 powerpc, libc++ will not be enabled by default, so libc++ should be
2069 built (with clang) and installed first. If both clang and libc++ are
2070 missing, build clang first, then use it to build libc++.
2072 On 8.x and earlier installations, upgrade to 9.x first, and then follow
2073 the instructions for 9.x above.
2075 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
2076 default, and do not build clang.
2078 Many embedded systems are resource constrained, and will not be able to
2079 build clang in a reasonable time, or in some cases at all. In those
2080 cases, cross building bootable systems on amd64 is a workaround.
2082 This new version of clang introduces a number of new warnings, of which
2083 the following are most likely to appear:
2087 This warns in two cases, for both C and C++:
2088 * When the code is trying to take the absolute value of an unsigned
2089 quantity, which is effectively a no-op, and almost never what was
2090 intended. The code should be fixed, if at all possible. If you are
2091 sure that the unsigned quantity can be safely cast to signed, without
2092 loss of information or undefined behavior, you can add an explicit
2093 cast, or disable the warning.
2095 * When the code is trying to take an absolute value, but the called
2096 abs() variant is for the wrong type, which can lead to truncation.
2097 If you want to disable the warning instead of fixing the code, please
2098 make sure that truncation will not occur, or it might lead to unwanted
2101 -Wtautological-undefined-compare and
2102 -Wundefined-bool-conversion
2104 These warn when C++ code is trying to compare 'this' against NULL, while
2105 'this' should never be NULL in well-defined C++ code. However, there is
2106 some legacy (pre C++11) code out there, which actively abuses this
2107 feature, which was less strictly defined in previous C++ versions.
2109 Squid and openjdk do this, for example. The warning can be turned off
2110 for C++98 and earlier, but compiling the code in C++11 mode might result
2111 in unexpected behavior; for example, the parts of the program that are
2112 unreachable could be optimized away.
2115 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
2116 kernel sources have been removed. The .h files remain, since some
2117 utilities include them. This will need to be fixed later.
2118 If "mount -t oldnfs ..." is attempted, it will fail.
2119 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
2120 the utilities will report errors.
2123 The handling of LOCAL_LIB_DIRS has been altered to skip addition of
2124 directories to top level SUBDIR variable when their parent
2125 directory is included in LOCAL_DIRS. Users with build systems with
2126 such hierarchies and without SUBDIR entries in the parent
2127 directory Makefiles should add them or add the directories to
2131 faith(4) and faithd(8) have been removed from the base system. Faith
2132 has been obsolete for a very long time.
2135 vt(4), the new console driver, is enabled by default. It brings
2136 support for Unicode and double-width characters, as well as
2137 support for UEFI and integration with the KMS kernel video
2140 You may need to update your console settings in /etc/rc.conf,
2141 most probably the keymap. During boot, /etc/rc.d/syscons will
2142 indicate what you need to do.
2144 vt(4) still has issues and lacks some features compared to
2145 syscons(4). See the wiki for up-to-date information:
2146 https://wiki.freebsd.org/Newcons
2148 If you want to keep using syscons(4), you can do so by adding
2149 the following line to /boot/loader.conf:
2153 pjdfstest has been integrated into kyua as an opt-in test suite.
2154 Please see share/doc/pjdfstest/README for more details on how to
2158 gperf has been removed from the base system for architectures
2159 that use clang. Ports that require gperf will obtain it from the
2163 pjdfstest has been moved from tools/regression/pjdfstest to
2167 At svn r271982, The default linux compat kernel ABI has been adjusted
2168 to 2.6.18 in support of the linux-c6 compat ports infrastructure
2169 update. If you wish to continue using the linux-f10 compat ports,
2170 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are
2171 encouraged to update their linux-compat packages to linux-c6 during
2172 their next update cycle.
2175 The ofwfb driver, used to provide a graphics console on PowerPC when
2176 using vt(4), no longer allows mmap() of all physical memory. This
2177 will prevent Xorg on PowerPC with some ATI graphics cards from
2178 initializing properly unless x11-servers/xorg-server is updated to
2182 The xdev targets have been converted to using TARGET and
2183 TARGET_ARCH instead of XDEV and XDEV_ARCH.
2186 The default unbound configuration has been modified to address
2187 issues with reverse lookups on networks that use private
2188 address ranges. If you use the local_unbound service, run
2189 "service local_unbound setup" as root to regenerate your
2190 configuration, then "service local_unbound reload" to load the
2194 The GNU texinfo and GNU info pages are not built and installed
2195 anymore, WITH_INFO knob has been added to allow to built and install
2197 UPDATE: see 20150102 entry on texinfo's removal
2200 The GNU readline library is now an INTERNALLIB - that is, it is
2201 statically linked into consumers (GDB and variants) in the base
2202 system, and the shared library is no longer installed. The
2203 devel/readline port is available for third party software that
2207 The Itanium architecture (ia64) has been removed from the list of
2208 known architectures. This is the first step in the removal of the
2212 Commit r268115 has added NFSv4.1 server support, merged from
2213 projects/nfsv4.1-server. Since this includes changes to the
2214 internal interfaces between the NFS related modules, a full
2215 build of the kernel and modules will be necessary.
2216 __FreeBSD_version has been bumped.
2219 The WITHOUT_VT_SUPPORT kernel config knob has been renamed
2220 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning
2221 which differs from the behaviour controlled by this knob.)
2224 Maximal length of the serial number in CTL was increased from 16 to
2225 64 chars, that breaks ABI. All CTL-related tools, such as ctladm
2226 and ctld, need to be rebuilt to work with a new kernel.
2229 The libatf-c and libatf-c++ major versions were downgraded to 0 and
2230 1 respectively to match the upstream numbers. They were out of
2231 sync because, when they were originally added to FreeBSD, the
2232 upstream versions were not respected. These libraries are private
2233 and not yet built by default, so renumbering them should be a
2234 non-issue. However, unclean source trees will yield broken test
2235 programs once the operator executes "make delete-old-libs" after a
2236 "make installworld".
2238 Additionally, the atf-sh binary was made private by moving it into
2239 /usr/libexec/. Already-built shell test programs will keep the
2240 path to the old binary so they will break after "make delete-old"
2243 If you are using WITH_TESTS=yes (not the default), wipe the object
2244 tree and rebuild from scratch to prevent spurious test failures.
2245 This is only needed once: the misnumbered libraries and misplaced
2246 binaries have been added to OptionalObsoleteFiles.inc so they will
2247 be removed during a clean upgrade.
2250 Clang and llvm have been upgraded to 3.4.1 release.
2253 We bogusly installed src.opts.mk in /usr/share/mk. This file should
2254 be removed to avoid issues in the future (and has been added to
2258 /etc/src.conf now affects only builds of the FreeBSD src tree. In the
2259 past, it affected all builds that used the bsd.*.mk files. The old
2260 behavior was a bug, but people may have relied upon it. To get this
2261 behavior back, you can .include /etc/src.conf from /etc/make.conf
2262 (which is still global and isn't changed). This also changes the
2263 behavior of incremental builds inside the tree of individual
2264 directories. Set MAKESYSPATH to ".../share/mk" to do that.
2265 Although this has survived make universe and some upgrade scenarios,
2266 other upgrade scenarios may have broken. At least one form of
2267 temporary breakage was fixed with MAKESYSPATH settings for buildworld
2268 as well... In cases where MAKESYSPATH isn't working with this
2269 setting, you'll need to set it to the full path to your tree.
2271 One side effect of all this cleaning up is that bsd.compiler.mk
2272 is no longer implicitly included by bsd.own.mk. If you wish to
2273 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2277 The lindev device has been removed since /dev/full has been made a
2278 standard device. __FreeBSD_version has been bumped.
2281 The knob WITHOUT_VI was added to the base system, which controls
2282 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2283 in order to reorder files share/termcap and didn't build ex(1) as a
2284 build tool, so building/installing with WITH_VI is highly advised for
2285 build hosts for older releases.
2287 This issue has been fixed in stable/9 and stable/10 in r277022 and
2288 r276991, respectively.
2291 The YES_HESIOD knob has been removed. It has been obsolete for
2292 a decade. Please move to using WITH_HESIOD instead or your builds
2293 will silently lack HESIOD.
2296 The uart(4) driver has been changed with respect to its handling
2297 of the low-level console. Previously the uart(4) driver prevented
2298 any process from changing the baudrate or the CLOCAL and HUPCL
2299 control flags. By removing the restrictions, operators can make
2300 changes to the serial console port without having to reboot.
2301 However, when getty(8) is started on the serial device that is
2302 associated with the low-level console, a misconfigured terminal
2303 line in /etc/ttys will now have a real impact.
2304 Before upgrading the kernel, make sure that /etc/ttys has the
2305 serial console device configured as 3wire without baudrate to
2306 preserve the previous behaviour. E.g:
2307 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
2310 Support for libwrap (TCP wrappers) in rpcbind was disabled by default
2311 to improve performance. To re-enable it, if needed, run rpcbind
2312 with command line option -W.
2315 Switched back to the GPL dtc compiler due to updates in the upstream
2316 dts files not being supported by the BSDL dtc compiler. You will need
2317 to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2318 may result while building dtb files during a kernel build if you fail
2319 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
2322 Clang and llvm have been upgraded to 3.4 release.
2325 The nve(4) driver has been removed. Please use the nfe(4) driver
2326 for NVIDIA nForce MCP Ethernet adapters instead.
2329 An ABI incompatibility crept into the libc++ 3.4 import in r261283.
2330 This could cause certain C++ applications using shared libraries built
2331 against the previous version of libc++ to crash. The incompatibility
2332 has now been fixed, but any C++ applications or shared libraries built
2333 between r261283 and r261801 should be recompiled.
2336 OpenSSH will now ignore errors caused by kernel lacking of Capsicum
2337 capability mode support. Please note that enabling the feature in
2338 kernel is still highly recommended.
2341 OpenSSH is now built with sandbox support, and will use sandbox as
2342 the default privilege separation method. This requires Capsicum
2343 capability mode support in kernel.
2346 The libelf and libdwarf libraries have been updated to newer
2347 versions from upstream. Shared library version numbers for
2348 these two libraries were bumped. Any ports or binaries
2349 requiring these two libraries should be recompiled.
2350 __FreeBSD_version is bumped to 1100006.
2353 If a Makefile in a tests/ directory was auto-generating a Kyuafile
2354 instead of providing an explicit one, this would prevent such
2355 Makefile from providing its own Kyuafile in the future during
2356 NO_CLEAN builds. This has been fixed in the Makefiles but manual
2357 intervention is needed to clean an objdir if you use NO_CLEAN:
2358 # find /usr/obj -name Kyuafile | xargs rm -f
2361 The behavior of gss_pseudo_random() for the krb5 mechanism
2362 has changed, for applications requesting a longer random string
2363 than produced by the underlying enctype's pseudo-random() function.
2364 In particular, the random string produced from a session key of
2365 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
2366 be different at the 17th octet and later, after this change.
2367 The counter used in the PRF+ construction is now encoded as a
2368 big-endian integer in accordance with RFC 4402.
2369 __FreeBSD_version is bumped to 1100004.
2372 The WITHOUT_ATF build knob has been removed and its functionality
2373 has been subsumed into the more generic WITHOUT_TESTS. If you were
2374 using the former to disable the build of the ATF libraries, you
2375 should change your settings to use the latter.
2378 The default version of mtree is nmtree which is obtained from
2379 NetBSD. The output is generally the same, but may vary
2380 slightly. If you found you need identical output adding
2381 "-F freebsd9" to the command line should do the trick. For the
2382 time being, the old mtree is available as fmtree.
2385 libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
2386 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
2387 1.1.4_8 and verify bsdyml not linked in, before running "make
2389 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
2391 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
2394 The stable/10 branch has been created in subversion from head
2401 Sometimes, obscure build problems are the result of environment
2402 poisoning. This can happen because the make utility reads its
2403 environment when searching for values for global variables. To run
2404 your build attempts in an "environmental clean room", prefix all make
2405 commands with 'env -i '. See the env(1) manual page for more details.
2406 Occasionally a build failure will occur with "make -j" due to a race
2407 condition. If this happens try building again without -j, and please
2408 report a bug if it happens consistently.
2410 When upgrading from one major version to another it is generally best to
2411 upgrade to the latest code in the currently installed branch first, then
2412 do an upgrade to the new branch. This is the best-tested upgrade path,
2413 and has the highest probability of being successful. Please try this
2414 approach if you encounter problems with a major version upgrade. Since
2415 the stable 4.x branch point, one has generally been able to upgrade from
2416 anywhere in the most recent stable branch to head / current (or even the
2417 last couple of stable branches). See the top of this file when there's
2420 The update process will emit an error on an attempt to perform a build
2421 or install from a FreeBSD version below the earliest supported version.
2422 When updating from an older version the update should be performed one
2423 major release at a time, including running `make delete-old` at each
2426 When upgrading a live system, having a root shell around before
2427 installing anything can help undo problems. Not having a root shell
2428 around can lead to problems if pam has changed too much from your
2429 starting point to allow continued authentication after the upgrade.
2431 This file should be read as a log of events. When a later event changes
2432 information of a prior event, the prior event should not be deleted.
2433 Instead, a pointer to the entry with the new information should be
2434 placed in the old entry. Readers of this file should also sanity check
2435 older entries before relying on them blindly. Authors of new entries
2436 should write them with this in mind.
2440 When upgrading the boot ZFS pool to a new version, always follow
2443 1.) recompile and reinstall the ZFS boot loader and boot block
2444 (this is part of "make buildworld" and "make installworld")
2446 2.) update the ZFS boot block on your boot drive
2448 The following example updates the ZFS boot block on the
2449 freebsd-boot partition of a GPT partitioned drive ada0:
2450 "gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2451 The value $N will typically be 1 (if booting from BIOS) or 2 (if
2454 Non-boot pools do not need these updates.
2458 If you are updating from a prior version of FreeBSD (even one just
2459 a few days old), you should follow this procedure. It is the most
2460 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
2462 make kernel-toolchain
2463 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
2464 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
2466 To test a kernel once
2467 ---------------------
2468 If you just want to boot a kernel once (because you are not sure
2469 if it works, or if you want to boot a known bad kernel to provide
2470 debugging information) run
2471 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
2472 nextboot -k testkernel
2474 To rebuild everything and install it on the current system.
2475 -----------------------------------------------------------
2476 # Note: sometimes if you are running current you gotta do more than
2477 # is listed here if you are upgrading from a really old current.
2479 <make sure you have good level 0 dumps>
2481 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2482 make installkernel KERNCONF=YOUR_KERNEL_HERE
2484 <reboot in single user> [3]
2491 To cross-install current onto a separate partition
2492 --------------------------------------------------
2493 # In this approach we use a separate partition to hold
2494 # current's root, 'usr', and 'var' directories. A partition
2495 # holding "/", "/usr" and "/var" should be about 2GB in
2498 <make sure you have good level 0 dumps>
2501 make buildkernel KERNCONF=YOUR_KERNEL_HERE
2502 <maybe newfs current's root partition>
2503 <mount current's root partition on directory ${CURRENT_ROOT}>
2504 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
2505 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
2506 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
2507 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
2508 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
2509 <reboot into current>
2510 <do a "native" rebuild/install as described in the previous section>
2511 <maybe install compatibility libraries from ports/misc/compat*>
2515 To upgrade in-place from stable to current
2516 ----------------------------------------------
2517 <make sure you have good level 0 dumps>
2519 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8]
2520 make installkernel KERNCONF=YOUR_KERNEL_HERE
2522 <reboot in single user> [3]
2529 Make sure that you've read the UPDATING file to understand the
2530 tweaks to various things you need. At this point in the life
2531 cycle of current, things change often and you are on your own
2532 to cope. The defaults can also change, so please read ALL of
2533 the UPDATING entries.
2535 Also, if you are tracking -current, you must be subscribed to
2536 freebsd-current@freebsd.org. Make sure that before you update
2537 your sources that you have read and understood all the recent
2538 messages there. If in doubt, please track -stable which has
2539 much fewer pitfalls.
2541 [1] If you have third party modules, such as vmware, you should disable
2542 them at this point so they don't crash your system on
2543 reboot. Alternatively, you should rebuild all the modules you have in
2544 your system and install them as well. If you are running -current, you
2545 should seriously consider placing all sources to all the modules for
2546 your system (or symlinks to them) in /usr/local/sys/modules so this
2547 happens automatically. If all your modules come from ports, then adding
2548 the port origin directories to PORTS_MODULES instead is also automatic
2550 PORTS_MODULES+=x11/nvidia-driver
2552 [3] From the bootblocks, boot -s, and then do
2556 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed
2557 cd src # full path to source
2558 adjkerntz -i # if CMOS is wall time
2559 Also, when doing a major release upgrade, it is required that you boot
2560 into single user mode to do the installworld.
2562 [4] Note: This step is non-optional. Failure to do this step
2563 can result in a significant reduction in the functionality of the
2564 system. Attempting to do it by hand is not recommended and those
2565 that pursue this avenue should read this file carefully, as well
2566 as the archives of freebsd-current and freebsd-hackers mailing lists
2567 for potential gotchas. The -U option is also useful to consider.
2568 See mergemaster(8) for more information.
2570 [5] Usually this step is a no-op. However, from time to time
2571 you may need to do this if you get unknown user in the following
2572 step. It never hurts to do it all the time. You may need to
2573 install a new mergemaster (cd src/usr.sbin/mergemaster && make
2574 install) after the buildworld before this step if you last updated
2575 from current before 20130425 or from -stable before 20130430.
2577 [6] This only deletes old files and directories. Old libraries
2578 can be deleted by "make delete-old-libs", but you have to make
2579 sure that no program is using those libraries anymore.
2581 [8] The new kernel must be able to run existing binaries used by an
2582 installworld. When upgrading across major versions, the new kernel's
2583 configuration must include the correct COMPAT_FREEBSD<n> option for
2584 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure
2585 to do so may leave you with a system that is hard to boot to recover. A
2586 GENERIC kernel will include suitable compatibility options to run
2587 binaries from older branches. Note that the ability to run binaries
2588 from unsupported branches is not guaranteed.
2590 Make sure that you merge any new devices from GENERIC since the
2591 last time you updated your kernel config file. Options also
2592 change over time, so you may need to adjust your custom kernels
2595 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2596 "?=" instead of the "=" assignment operator, so that buildworld can
2597 override the CPUTYPE if it needs to.
2599 MAKEOBJDIRPREFIX must be defined in an environment variable, and
2600 not on the command line, or in /etc/make.conf. buildworld will
2601 warn if it is improperly defined.
2604 This file contains a list, in reverse chronological order, of major
2605 breakages in tracking -current. It is not guaranteed to be a complete
2606 list of such breakages, and only contains entries since September 23, 2011.
2607 If you need to see UPDATING entries from before that date, you will need
2608 to fetch an UPDATING file from an older FreeBSD release.
