Please update your drm-kmod port to after the __FreeBSD_version 1400003
update.
+20210108:
+ PC Card attachments for all devices have been removed. In the case of
+ wi and cmx, the entire drivers were removed because they were only
+ PC Card devices. FreeBSD_version 1300134 should be used for this
+ since it was bumped so recently.
+
+20210107:
+ Transport-independent parts of HID support have been split off the USB
+ code in to separate subsystem. Kernel configs which include one of
+ ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
+ be updated with adding of "device hid" line.
+
+20210105:
+ ncurses installation has been modified to only keep the widechar
+ enabled version. Incremental build is broken for that change, so it
+ requires a clean build.
+
+20201223:
+ The FreeBSD project has migrated from Subversion to Git. Temporary
+ instructions can be found at
+ https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md
+ and other documents in that repo.
+
+20201216:
+ The services database has been updated to cover more of the basic
+ services expected in a modern system. The database is big enough
+ that it will cause issues in mergemaster in Releases previous to
+ 12.2 and 11.3, or in very old current systems from before r358154.
+
+20201215:
+ Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb)
+ may be installed from ports or packages.
+
+20201124:
+ ping6 has been merged into ping. It can now be called as "ping -6".
+ See ping(8) for details.
+
+20201108:
+ Default value of net.add_addr_allfibs has been changed to 0.
+ If you have multi-fib configuration and rely on existence of all
+ interface routes in every fib, you need to set the above sysctl to 1.
+
+20201030:
+ The internal pre-processor in the calendar(1) program has been
+ extended to support more C pre-processor commands (e.g. #ifdef, #else,
+ and #undef) and to detect unbalanced conditional statements.
+ Error messages have been extended to include the filename and line
+ number if processing stops to help fixing malformed data files.
+
+20201026:
+ All the data files for the calendar(1) program, except calendar.freebsd,
+ have been moved to the deskutils/calendar-data port, much like the
+ jewish calendar entries were moved to deskutils/hebcal years ago. After
+ make delete-old-files, you need to install it to retain full
+ functionality. calendar(1) will issue a reminder for files it can't
+ find.
+
+20200923:
+ LINT files are no longer generated. We now include the relevant NOTES
+ files. Note: This may cause conflicts with updating in some cases.
+ find sys -name LINT\* -delete
+ is suggested across this commit to remove the generated LINT files.
+
+ If you have tried to update with generated files there, the svn
+ command you want to un-auger the tree is
+ cd sys/amd64/conf
+ svn revert -R .
+ and then do the above find from the top level. Substitute 'amd64'
+ above with where the error message indicates a conflict.
+
+20200824:
+ OpenZFS support has been integrated. Do not upgrade root pools until
+ the loader is updated to support zstd. Furthermore, we caution against
+ 'zpool upgrade' for the next few weeks. The change should be transparent
+ unless you want to use new features.
+
+ Not all "NO_CLEAN" build scenarios work across these changes. Many
+ scenarios have been tested and fixed, but rebuilding kernels without
+ rebuilding world may fail.
+
+ The ZFS cache file has moved from /boot to /etc to match the OpenZFS
+ upstream default. A fallback to /boot has been added for mountroot.
+
+ Pool auto import behavior at boot has been moved from the kernel module
+ to an explicit "zpool import -a" in one of the rc scripts enabled by
+ zfs_enable=YES. This means your non-root zpools won't auto import until
+ you upgrade your /etc/rc.d files.
+
+20200824:
+ The resume code now notifies devd with the 'kernel' system
+ rather than the old 'kern' subsystem to be consistent with
+ other use. The old notification will be created as well, but
+ will be removed prior to FreeBSD 14.0.
+
+20200821:
+ r362275 changed the internal API between the kernel RPC and the
+ NFS modules. As such, all the modules must be recompiled from
+ sources.
+
+20200817:
+ r364330 modified the internal API used between the NFS modules.
+ As such, all the NFS modules must be re-compiled from sources.
+
+20200816:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 11.0.0. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20200810:
+ r364092 modified the internal ABI used between the kernel NFS
+ modules. As such, all of these modules need to be rebuilt
+ from sources, so a version bump was done.
+
+20200807:
+ Makefile.inc has been updated to work around the issue documented in
+ 20200729. It was a case where the optimization of using symbolic links
+ to point to binaries created a situation where we'd run new binaries
+ with old libraries starting midway through the installworld process.
+
+20200729:
+ r363679 has redefined some undefined behavior in regcomp(3); notably,
+ extraneous escapes of most ordinary characters will no longer be
+ accepted. An exp-run has identified all of the problems with this in
+ ports, but other non-ports software may need extra escapes removed to
+ continue to function.
+
+ Because of this change, installworld may encounter the following error
+ from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that
+ you do not halt installworld. Instead, let it run to completion (whether
+ successful or not) and run installworld once more.
+
+20200627:
+ A new implementation of bc and dc has been imported in r362681. This
+ implementation corrects non-conformant behavior of the previous bc
+ and adds GNU bc compatible options. It offers a number of extensions,
+ is much faster on large values, and has support for message catalogs
+ (a number of languages are already supported, contributions of further
+ languages welcome). The option WITHOUT_GH_BC can be used to build the
+ world with the previous versions of bc and dc.
+
+20200625:
+ r362639 changed the internal API used between the NFS kernel modules.
+ As such, they all need to be rebuilt from sources.
+
+20200613:
+ r362158 changed the arguments for VFS_CHECKEXP(). As such, any
+ out of tree file systems need to be modified and rebuilt.
+ Also, any file systems that are modules must be rebuilt.
+
+20200604:
+ read(2) of a directory fd is now rejected by default. root may
+ re-enable it for system root only on non-ZFS filesystems with the
+ security.bsd.allow_read_dir sysctl(8) MIB if
+ security.bsd.suser_enabled=1.
+
+ It may be advised to setup aliases for grep to default to `-d skip` if
+ commonly non-recursively grepping a list that includes directories and
+ the potential for the resulting stderr output is not tolerable. Example
+ aliases are now installed, commented out, in /root/.cshrc and
+ /root/.shrc.
+
+20200523:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 10.0.1. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20200512:
+ Support for obsolete compilers has been removed from the build system.
+ Clang 6 and GCC 6.4 are the minimum supported versions.
+
+20200424:
+ closefrom(2) has been moved under COMPAT12, and replaced in libc with a
+ stub that calls close_range(2). If using a custom kernel configuration,
+ you may want to ensure that the COMPAT_FREEBSD12 option is included, as
+ a slightly older -CURRENT userland and older FreeBSD userlands may not
+ be functional without closefrom(2).
+
+20200414:
+ Upstream DTS from Linux 5.6 was merged and they now have the SID
+ and THS (Secure ID controller and THermal Sensor) node present.
+ The DTB overlays have now been removed from the tree for the H3/H5 and
+ A64 SoCs and the aw_sid and aw_thermal driver have been updated to
+ deal with upstream DTS. If you are using those overlays you need to
+ remove them from loader.conf and update the DTBs on the FAT partition.
+
+20200310:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 10.0.0. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20200309:
+ The amd(8) automount daemon has been removed from the source tree.
+ As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting.
+ amd is still available in the sysutils/am-utils port.
+
+20200301:
+ Removed brooktree driver (bktr.4) from the tree.
+
+20200229:
+ The WITH_GPL_DTC option has been removed. The BSD-licenced device tree
+ compiler in usr.bin/dtc is used on all architectures which use dtc, and
+ the GPL dtc is available (if needed) from the sysutils/dtc port.
+
+20200229:
+ The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind
+ is used by all supported CPU architectures.
+
+20200229:
+ GCC 4.2.1 has been removed from the tree. The WITH_GCC,
+ WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available.
+ Users who wish to build FreeBSD with GCC must use the external toolchain
+ ports or packages.
+
+20200220:
+ ncurses has been updated to a newer version (6.2-20200215). Given the ABI
+ has changed, users will have to rebuild all the ports that are linked to
+ ncurses.
+
+20200217:
+ The size of struct vnet and the magic cookie have changed.
+ Users need to recompile libkvm and all modules using VIMAGE
+ together with their new kernel.
+
+20200212:
+ Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB,
+ NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update
+ your Makefiles and scripts to define MK_<var>=no instead as required.
+
+ One exception to this is that program or library Makefiles should
+ define MAN to empty rather than setting MK_MAN=no.
+
+20200108:
+ Clang/LLVM is now the default compiler and LLD the default
+ linker for riscv64.
+
+20200107:
+ make universe no longer uses GCC 4.2.1 on any architectures.
+ Architectures not supported by in-tree Clang/LLVM require an
+ external toolchain package.
+
+20200104:
+ GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1
+ retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX
+ options default to off for all supported CPU architectures. As a
+ short-term transition aid they may be enabled via WITH_* options.
+ GCC 4.2.1 is expected to be removed from the tree on 2020-03-31.
+
+20200102:
+ Support for armv5 has been disconnected and is being removed. The
+ machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid.
+ You must now use a MACHINE_ARCH of armv6 or armv7. The default
+ MACHINE_ARCH for MACHINE=arm is now armv7.
+
+20191226:
+ Clang/LLVM is now the default compiler for all powerpc architectures.
+ LLD is now the default linker for powerpc64. The change for powerpc64
+ also includes a change to the ELFv2 ABI, incompatible with the existing
+ ABI.
+
+20191226:
+ Kernel-loadable random(4) modules are no longer unloadable.
+
+20191222:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 9.0.1. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20191212:
+ r355677 has modified the internal interface used between the
+ NFS modules in the kernel. As such, they must all be upgraded
+ simultaneously. I will do a version bump for this.
+
+20191205:
+ The root certificates of the Mozilla CA Certificate Store have been
+ imported into the base system and can be managed with the certctl(8)
+ utility. If you have installed the security/ca_root_nss port or package
+ with the ETCSYMLINK option (the default), be advised that there may be
+ differences between those included in the port and those included in
+ base due to differences in nss branch used as well as general update
+ frequency. Note also that certctl(8) cannot manage certs in the
+ format used by the security/ca_root_nss port.
+
+20191120:
+ The amd(8) automount daemon has been disabled by default, and will be
+ removed in the future. As of FreeBSD 10.1 the autofs(5) is available
+ for automounting.
+
+20191107:
+ The nctgpio and wbwd drivers have been moved to the superio bus.
+ If you have one of these drivers in a kernel configuration, then
+ you should add device superio to it. If you use one of these drivers
+ as a module and you compile a custom set of modules, then you should
+ add superio to the set.
+
+20191021:
+ KPIs for network drivers to access interface addresses have changed.
+ Users need to recompile NIC driver modules together with kernel.
+
+20191021:
+ The net.link.tap.user_open sysctl no longer prevents user opening of
+ already created /dev/tapNN devices. Access is still controlled by
+ node permissions, just like tun devices. The net.link.tap.user_open
+ sysctl is now used only to allow users to perform devfs cloning of
+ tap devices, and the subsequent open may not succeed if the user is not
+ in the appropriate group. This sysctl may be deprecated/removed
+ completely in the future.
+
+20191009:
+ mips, powerpc, and sparc64 are no longer built as part of
+ universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If
+ not defined, mips, powerpc, and sparc64 builds will look for
+ the xtoolchain binaries and if installed use them for universe
+ builds. As llvm 9.0 becomes vetted for these architectures, they
+ will be removed from the list.
+
+20191009:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 9.0.0. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20191003:
+ The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from
+ GENERIC. They are available as modules and can be loaded by adding
+ to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES",
+ hptnr_load="YES", or hptrr_load="YES", respectively.
+
+20190913:
+ ntpd no longer by default locks its pages in memory, allowing them
+ to be paged out by the kernel. Use rlimit memlock to restore
+ historic BSD behaviour. For example, add "rlimit memlock 32"
+ to ntp.conf to lock up to 32 MB of ntpd address space in memory.
+
+20190823:
+ Several of ping6's options have been renamed for better consistency
+ with ping. If you use any of -ARWXaghmrtwx, you must update your
+ scripts. See ping6(8) for details.
+
+20190727:
+ The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
+ and the "-o sync_unmount" and "-o init_backgrounded" mount options have
+ been removed from mount_fusefs(8). You can safely remove them from
+ your scripts, because they had no effect.
+
+ The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,
+ vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable,
+ vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate
+ sysctls have been removed. If you felt the need to set any of them to
+ a non-default value, please tell asomers@FreeBSD.org why.
+
+20190713:
+ Default permissions on the /var/account/acct file (and copies of it
+ rotated by periodic daily scripts) are changed from 0644 to 0640
+ because the file contains sensitive information that should not be
+ world-readable. If the /var/account directory must be created by
+ rc.d/accounting, the mode used is now 0750. Admins who use the
+ accounting feature are encouraged to change the mode of an existing
+ /var/account directory to 0750 or 0700.
+
+20190620:
+ Entropy collection and the /dev/random device are no longer optional
+ components. The "device random" option has been removed.
+ Implementations of distilling algorithms can still be made loadable
+ with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko).
+
+20190612:
+ Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have
+ been upgraded to 8.0.1. Please see the 20141231 entry below for
+ information about prerequisites and upgrading, if you are not already
+ using clang 3.5.0 or higher.
+
+20190608:
+ A fix was applied to i386 kernel modules to avoid panics with
+ dpcpu or vnet. Users need to recompile i386 kernel modules
+ having pcpu or vnet sections or they will refuse to load.
+
+20190513:
+ User-wired pages now have their own counter,
+ vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed
+ to vm.max_user_wired and changed from an unsigned int to an unsigned
+ long. bhyve VMs wired with the -S are now subject to the user
+ wiring limit; the vm.max_user_wired sysctl may need to be tuned to
+ avoid running into the limit.
+
+20190507:
+ The IPSEC option has been removed from GENERIC. Users requiring
+ ipsec(4) must now load the ipsec(4) kernel module.
+
+20190507:
+ The tap(4) driver has been folded into tun(4), and the module has been
+ renamed to tuntap. You should update any kld_list="if_tap" or
+ kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
+ if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
+ module instead, and "device tap" or "device tun" entries in kernel
+ config files to select the tuntap device instead.
+
+20190418:
+ The following knobs have been added related to tradeoffs between
+ safe use of the random device and availability in the absence of
+ entropy:
+
+ kern.random.initial_seeding.bypass_before_seeding: tunable; set
+ non-zero to bypass the random device prior to seeding, or zero to
+ block random requests until the random device is initially seeded.
+ For now, set to 1 (unsafe) by default to restore pre-r346250 boot
+ availability properties.
+
+ kern.random.initial_seeding.read_random_bypassed_before_seeding:
+ read-only diagnostic sysctl that is set when bypass is enabled and
+ read_random(9) is bypassed, to enable programmatic handling of this
+ initial condition, if desired.
+
+ kern.random.initial_seeding.arc4random_bypassed_before_seeding:
+ Similar to the above, but for arc4random(9) initial seeding.
+
+ kern.random.initial_seeding.disable_bypass_warnings: tunable; set
+ non-zero to disable warnings in dmesg when the same conditions are
+ met as for the diagnostic sysctls above. Defaults to zero, i.e.,
+ produce warnings in dmesg when the conditions are met.
+
+20190416:
+ The loadable random module KPI has changed; the random_infra_init()
+ routine now requires a 3rd function pointer for a bool (*)(void)
+ method that returns true if the random device is seeded (and
+ therefore unblocked).
+
+20190404:
+ r345895 reverts r320698. This implies that an nfsuserd(8) daemon
+ built from head sources between r320757 (July 6, 2017) and
+ r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
+ is added to the command line.
+ nfsuserd daemons built from head sources that are post-r338192 are
+ not affected and should continue to work.
+
+20190320:
+ The fuse(4) module has been renamed to fusefs(4) for consistency with
+ other filesystems. You should update any kld_load="fuse" entries in
+ /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
+ "options FUSE" entries in kernel config files.
+
+20190304:
+ Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
+ 8.0.0. Please see the 20141231 entry below for information about
+ prerequisites and upgrading, if you are not already using clang 3.5.0
+ or higher.
+
+20190226:
+ geom_uzip(4) depends on the new module xz. If geom_uzip is statically
+ compiled into your custom kernel, add 'device xz' statement to the
+ kernel config.
+
+20190219:
+ drm and drm2 have been removed from the tree. Please see
+ https://wiki.freebsd.org/Graphics for the latest information on
+ migrating to the drm ports.
+
+20190131:
+ Iflib is no longer unconditionally compiled into the kernel. Drivers
+ using iflib and statically compiled into the kernel, now require
+ the 'device iflib' config option. For the same drivers loaded as
+ modules on kernels not having 'device iflib', the iflib.ko module
+ is loaded automatically.
+
+20190125:
+ The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration
+ options no longer exist since r343219 and r343427 respectively;
+ nothing uses them, so they should be just removed from custom
+ kernel config files.
+
+20181230:
+ r342635 changes the way efibootmgr(8) works by requiring users to add
+ the -b (bootnum) parameter for commands where the bootnum was previously
+ specified with each option. For example 'efibootmgr -B 0001' is now
+ 'efibootmgr -B -b 0001'.
+
+20181220:
+ r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
+ in the same as it is applied to NFSv2 and 3. This implies that NFSv4
+ servers that have vfs.nfsd.nfs_privport set will only allow mounts
+ from clients using a reserved port. Since both the FreeBSD and Linux
+ NFSv4 clients use reserved ports by default, this should not affect
+ most NFSv4 mounts.
+
+20181219:
+ The XLP config has been removed. We can't support 64-bit atomics in this
+ kernel because it is running in 32-bit mode. XLP users must transition
+ to running a 64-bit kernel (XLP64 or XLPN32).
+
+ The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
+ the preferred emulator today and we don't need two different ones.
+
+ The old sibyte / swarm / Broadcom BCM1250 support has been
+ removed from the mips port.
+
+20181211:
+ Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
+ 7.0.1. Please see the 20141231 entry below for information about
+ prerequisites and upgrading, if you are not already using clang 3.5.0
+ or higher.
+
+20181211:
+ Remove the timed and netdate programs from the base tree. Setting
+ the time with these daemons has been obsolete for over a decade.
+
+20181126:
+ On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld
+ linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as
+ it produces broken binaries when ifuncs are in use. Users needing
+ GNU ld should install the binutils port or package.
+
+20181123:
+ The BSD crtbegin and crtend code has been enabled by default. It has
+ had extensive testing on amd64, arm64, and i386. It can be disabled
+ by building a world with -DWITHOUT_BSD_CRTBEGIN.
+
+20181115:
+ The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue)
+ has been converted to a port (misc/ctm) and will be removed from
+ FreeBSD-13. It is available as a package (ctm) for all supported
+ FreeBSD versions.
+
+20181110:
+ The default newsyslog.conf(5) file has been changed to only include
+ files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if
+ the filenames end in '.conf' and do not begin with a '.'.
+
+ You should check the configuration files in these two directories match
+ this naming convention. You can verify which configuration files are
+ being included using the command:
+ $ newsyslog -Nrv
+
+20181015:
+ Ports for the DRM modules have been simplified. Now, amd64 users should
+ just install the drm-kmod port. All others should install
+ drm-legacy-kmod.
+
+ Graphics hardware that's newer than about 2010 usually works with
+ drm-kmod. For hardware older than 2013, however, some users will need
+ to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
+ than 2008 usually only works in drm-legacy-kmod. The graphics team can
+ only commit to hardware made since 2013 due to the complexity of the
+ market and difficulty to test all the older cards effectively. If you
+ have hardware supported by drm-kmod, you are strongly encouraged to use
+ that as you will get better support.
+
+ Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
+ elsewhere, the drm and drm2 modules will be eliminated from the src base
+ soon (with a limited exception for arm). Please update to the package
+ asap and report any issues to x11@freebsd.org.
+
+ Generally, anybody using the drm*-kmod packages should add
+ WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
+ cross-threading surprises, especially with automatic driver
+ loading from X11 startup. These will become the defaults in 13-current
+ shortly.
+
+20181012:
+ The ixlv(4) driver has been renamed to iavf(4). As a consequence,
+ custom kernel and module loading configuration files must be updated
+ accordingly. Moreover, interfaces previous presented as ixlvN to the
+ system are now exposed as iavfN and network configuration files must
+ be adjusted as necessary.
+
+20181009:
+ OpenSSL has been updated to version 1.1.1. This update included
+ additional various API changes throughout the base system. It is
+ important to rebuild third-party software after upgrading. The value
+ of __FreeBSD_version has been bumped accordingly.
+
+20181006:
+ The legacy DRM modules and drivers have now been added to the loader's
+ module blacklist, in favor of loading them with kld_list in rc.conf(5).
+ The module blacklist may be overridden with the loader.conf(5)
+ 'module_blacklist' variable, but loading them via rc.conf(5) is strongly
+ encouraged.
+
+20181002:
+ The cam(4) based nda(4) driver will be used over nvd(4) by default on
+ powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
+ loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
+ driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the
+ nda device name.
+
+20180913:
+ Reproducible build mode is now on by default, in preparation for
+ FreeBSD 12.0. This eliminates build metadata such as the user,
+ host, and time from the kernel (and uname), unless the working tree
+ corresponds to a modified checkout from a version control system.
+ The previous behavior can be obtained by setting the /etc/src.conf
+ knob WITHOUT_REPRODUCIBLE_BUILD.
+
+20180826:
+ The Yarrow CSPRNG has been removed from the kernel as it has not been
+ supported by its designers since at least 2003. Fortuna has been the
+ default since FreeBSD-11.
+
+20180822:
+ devctl freeze/thaw have gone into the tree, the rc scripts have been
+ updated to use them and devmatch has been changed. You should update
+ kernel, userland and rc scripts all at the same time.
+
+20180818:
+ The default interpreter has been switched from 4th to Lua.
+ LOADER_DEFAULT_INTERP, documented in build(7), will override the default
+ interpreter. If you have custom FORTH code you will need to set
+ LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
+ src.conf for the build. This will create default hard links between
+ loader and loader_4th instead of loader and loader_lua, the new default.
+ If you are using UEFI it will create the proper hard link to loader.efi.
+
+ bhyve uses userboot.so. It remains 4th-only until some issues are solved
+ regarding coexisting with multiple versions of FreeBSD are resolved.
+
+20180815:
+ ls(1) now respects the COLORTERM environment variable used in other
+ systems and software to indicate that a colored terminal is both
+ supported and desired. If ls(1) is suddenly emitting colors, they may
+ be disabled again by either removing the unwanted COLORTERM from your
+ environment, or using `ls --color=never`. The ls(1) specific CLICOLOR
+ may not be observed in a future release.
+
+20180808:
+ The default pager for most commands has been changed to "less". To
+ restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
+ your environment.
+
+20180731:
+ The jedec_ts(4) driver has been removed. A superset of its functionality
+ is available in the jedec_dimm(4) driver, and the manpage for that
+ driver includes migration instructions. If you have "device jedec_ts"
+ in your kernel configuration file, it must be removed.
+
+20180730:
+ amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
+ This should have no effect if the kernel is booted via BIOS/legacy boot.
+ EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
+ has a buggy firmware that prevents a successful boot due to use of
+ runtime services.
+
+20180727:
+ Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
+ support has been removed from the tree. These ports were
+ obsolete and/or known to be broken for many years.
+
+20180723:
+ loader.efi has been augmented to participate more fully in the
+ UEFI boot manager protocol. loader.efi will now look at the
+ BootXXXX environment variable to determine if a specific kernel
+ or root partition was specified. XXXX is derived from BootCurrent.
+ efibootmgr(8) manages these standard UEFI variables.
+
+20180720:
+ zfsloader's functionality has now been folded into loader.
+ zfsloader is no longer necessary once you've updated your
+ boot blocks. For a transition period, we will install a
+ hardlink for zfsloader to loader to allow a smooth transition
+ until the boot blocks can be updated (hard link because old
+ zfs boot blocks don't understand symlinks).
+
+20180719:
+ ARM64 now have efifb support, if you want to have serial console
+ on your arm64 board when an screen is connected and the bootloader
+ setup a frame buffer for us to use, just add :
+ boot_serial=YES
+ boot_multicons=YES
+ in /boot/loader.conf
+ For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
+ an screen connected as the firmware will setup a frame buffer are that
+ u-boot will expose as an EFI frame buffer.
+
+20180719:
+ New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster
+ or take steps to update /etc/passwd before doing installworld on
+ existing systems. Do not skip the "mergemaster -Fp" step before
+ installworld, as described in the update procedures near the bottom
+ of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd
+ if the new mac_ntpd(4) policy is available, unless ntpd_flags or
+ the ntp config file contain options that change file/dir locations.
+ When such options (e.g., "statsdir" or "crypto") are used, ntpd can
+ still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
+ taking steps to ensure that all required files/dirs are accessible
+ by the ntpd user.
+
+20180717:
+ Big endian arm support has been removed.
+
+20180711:
+ The static environment setup in kernel configs is no longer mutually
+ exclusive with the loader(8) environment by default. In order to
+ restore the previous default behavior of disabling the loader(8)
+ environment if a static environment is present, you must specify
+ loader_env.disabled=1 in the static environment.
+
+20180705:
+ The ABI of syscalls used by management tools like sockstat and
+ netstat has been broken to allow 32-bit binaries to work on
+ 64-bit kernels without modification. These programs will need
+ to match the kernel in order to function. External programs may
+ require minor modifications to accommodate a change of type in
+ structures from pointers to 64-bit virtual addresses.
+
+20180702:
+ On i386 and amd64 atomics are now inlined. Out of tree modules using
+ atomics will need to be rebuilt.
+
+20180701:
+ The '%I' format in the kern.corefile sysctl limits the number of
+ core files that a process can generate to the number stored in the
+ debug.ncores sysctl. The '%I' format is replaced by the single digit
+ index. Previously, if all indexes were taken the kernel would overwrite
+ only a core file with the highest index in a filename.
+ Currently the system will create a new core file if there is a free
+ index or if all slots are taken it will overwrite the oldest one.
+
+20180630:
+ Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
+ 6.0.1. Please see the 20141231 entry below for information about
+ prerequisites and upgrading, if you are not already using clang 3.5.0
+ or higher.
+
+20180628:
+ r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
+ needed to be changed to work with it. This change was made with r335763
+ and requires a mergemaster / etcupdate / etc to update the installed
+ file.
+
+20180612:
+ r334930 changed the interface between the NFS modules, so they all
+ need to be rebuilt. r335018 did a __FreeBSD_version bump for this.
+
+20180530:
+ As of r334391 lld is the default amd64 system linker; it is installed
+ as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no
+ longer necessary.
+
+20180530:
+ The kernel / userland interface for devinfo changed, so you'll
+ need a new kernel and userland as a pair for it to work (rebuilding
+ lib/libdevinfo is all that's required). devinfo and devmatch will
+ not work, but everything else will when there's a mismatch.
+
+20180523:
+ The on-disk format for hwpmc callchain records has changed to include
+ threadid corresponding to a given record. This changes the field offsets
+ and thus requires that libpmcstat be rebuilt before using a kernel
+ later than r334108.
+
+20180517:
+ The vxge(4) driver has been removed. This driver was introduced into
+ HEAD one week before the Exar left the Ethernet market and is not
+ known to be used. If you have device vxge in your kernel config file
+ it must be removed.
+
+20180510:
+ The amd64 kernel now requires a ld that supports ifunc to produce a
+ working kernel, either lld or a newer binutils. lld is built by default
+ on amd64, and the 'buildkernel' target uses it automatically. However,
+ it is not the default linker, so building the kernel the traditional
+ way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
+ binutils port/package). lld will soon be default, and this requirement
+ will go away.
+
+ NOTE: As of r334391 lld is the default system linker on amd64, and no
+ workaround is necessary.
+
+20180508:
+ The nxge(4) driver has been removed. This driver was for PCI-X 10g
+ cards made by s2io/Neterion. The company was acquired by Exar and
+ no longer sells or supports Ethernet products. If you have device
+ nxge in your kernel config file it must be removed.
+
+20180504:
+ The tz database (tzdb) has been updated to 2018e. This version more
+ correctly models time stamps in time zones with negative DST such as
+ Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
+ Africa/Windhoek (1994/2017). This does not affect the UT offsets, only
+ time zone abbreviations and the tm_isdst flag.
+
+20180502:
+ The ixgb(4) driver has been removed. This driver was for an early and
+ uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
+ quickly shifted to the long lived ixgbe family. If you have device
+ ixgb in your kernel config file it must be removed.
+
+20180501:
+ The lmc(4) driver has been removed. This was a WAN interface
+ card that was already reportedly rare in 2003, and had an ambiguous
+ license. If you have device lmc in your kernel config file it must
+ be removed.
+
+20180413:
+ Support for Arcnet networks has been removed. If you have device
+ arcnet or device cm in your kernel config file they must be
+ removed.
+
+20180411:
+ Support for FDDI networks has been removed. If you have device
+ fddi or device fpa in your kernel config file they must be
+ removed.
+
+20180406:
+ In addition to supporting RFC 3164 formatted messages, the
+ syslogd(8) service is now capable of parsing RFC 5424 formatted
+ log messages. The main benefit of using RFC 5424 is that clients
+ may now send log messages with timestamps containing year numbers,
+ microseconds and time zone offsets.
+
+ Similarly, the syslog(3) C library function has been altered to
+ send RFC 5424 formatted messages to the local system logging
+ daemon. On systems using syslogd(8), this change should have no
+ negative impact, as long as syslogd(8) and the C library are
+ updated at the same time. On systems using a different system
+ logging daemon, it may be necessary to make configuration
+ adjustments, depending on the software used.
+
+ When using syslog-ng, add the 'syslog-protocol' flag to local
+ input sources to enable parsing of RFC 5424 formatted messages:
+
+ source src {
+ unix-dgram("/var/run/log" flags(syslog-protocol));
+ }
+
+ When using rsyslog, disable the 'SysSock.UseSpecialParser' option
+ of the 'imuxsock' module to let messages be processed by the
+ regular RFC 3164/5424 parsing pipeline:
+
+ module(load="imuxsock" SysSock.UseSpecialParser="off")
+
+ Do note that these changes only affect communication between local
+ applications and syslogd(8). The format that syslogd(8) uses to
+ store messages on disk or forward messages to other systems
+ remains unchanged. syslogd(8) still uses RFC 3164 for these
+ purposes. Options to customize this behaviour will be added in the
+ future. Utilities that process log files stored in /var/log are
+ thus expected to continue to function as before.
+
+ __FreeBSD_version has been incremented to 1200061 to denote this
+ change.
+
+20180328:
+ Support for token ring networks has been removed. If you
+ have "device token" in your kernel config you should remove
+ it. No device drivers supported token ring.
+
+20180323:
+ makefs was modified to be able to tag ISO9660 El Torito boot catalog
+ entries as EFI instead of overloading the i386 tag as done previously.
+ The amd64 mkisoimages.sh script used to build amd64 ISO images for
+ release was updated to use this. This may mean that makefs must be
+ updated before "make cdrom" can be run in the release directory. This
+ should be as simple as:
+
+ $ cd $SRCDIR/usr.sbin/makefs
+ $ make depend all install
+
+20180212:
+ FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for
+ now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf.
+ Co-existence for the transition period will come shortly. Booting is a
+ complex environment and test coverage for Lua-enabled loaders has been
+ thin, so it would be prudent to assume it might not work and make
+ provisions for backup boot methods.
+
+20180211:
+ devmatch functionality has been turned on in devd. It will automatically
+ load drivers for unattached devices. This may cause unexpected drivers
+ to be loaded. Please report any problems to current@ and
+ imp@freebsd.org.
+
+20180114:
+ Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
+ 6.0.0. Please see the 20141231 entry below for information about
+ prerequisites and upgrading, if you are not already using clang 3.5.0
+ or higher.
+
+20180110:
+ LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker.
+ This means it is used to link the kernel and userland libraries and
+ executables, but is not yet installed as /usr/bin/ld by default.
+
+ To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set
+ WITHOUT_LLD_BOOTSTRAP=yes
+
+20180110:
+ On i386, pmtimer has been removed. Its functionality has been folded
+ into apm. It was a no-op on ACPI in current for a while now (but was
+ still needed on i386 in FreeBSD 11 and earlier). Users may need to
+ remove it from kernel config files.
+
+20180104:
+ The use of RSS hash from the network card aka flowid has been
+ disabled by default for lagg(4) as it's currently incompatible with
+ the lacp and loadbalance protocols.
+
+ This can be re-enabled by setting the following in loader.conf:
+ net.link.lagg.default_use_flowid="1"
+
+20180102:
+ The SW_WATCHDOG option is no longer necessary to enable the
+ hardclock-based software watchdog if no hardware watchdog is
+ configured. As before, SW_WATCHDOG will cause the software
+ watchdog to be enabled even if a hardware watchdog is configured.
+
+20171215:
+ r326887 fixes the issue described in the 20171214 UPDATING entry.
+ r326888 flips the switch back to building GELI support always.
+
+20171214:
+ r362593 broke ZFS + GELI support for reasons unknown. However,
+ it also broke ZFS support generally, so GELI has been turned off
+ by default as the lesser evil in r326857. If you boot off ZFS and/or
+ GELI, it might not be a good time to update.
+
+20171125:
+ PowerPC users must update loader(8) by rebuilding world before
+ installing a new kernel, as the protocol connecting them has
+ changed. Without the update, loader metadata will not be passed
+ successfully to the kernel and users will have to enter their
+ root partition at the kernel mountroot prompt to continue booting.
+ Newer versions of loader can boot old kernels without issue.
+
+20171110:
+ The LOADER_FIREWIRE_SUPPORT build variable has been renamed to
+ WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed
+ to WITH/OUT_LOADER_GELI.
+
+20171106:
+ The naive and non-compliant support of posix_fallocate(2) in ZFS
+ has been removed as of r325320. The system call now returns EINVAL
+ when used on a ZFS file. Although the new behavior complies with the
+ standard, some consumers are not prepared to cope with it.
+ One known victim is lld prior to r325420.
+
+20171102:
+ Building in a FreeBSD src checkout will automatically create object
+ directories now rather than store files in the current directory if
+ 'make obj' was not ran. Calling 'make obj' is no longer necessary.
+ This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in
+ /etc/src-env.conf (not /etc/src.conf), or passing the option in the
+ environment.
+
+20171101:
+ The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native
+ builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified
+ /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old
+ format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf,
+ the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building.
+ The UNIFIED_OBJDIR option is a transitional feature that will be
+ removed for 12.0 release; please migrate to the new format for any
+ tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather
+ than hardcoding paths.
+
+20171028:
+ The native-xtools target no longer installs the files by default to the
*** 1220 LINES SKIPPED ***
