15a53ce3fcSGlen BarberNOTE TO PEOPLE WHO THINK THAT FreeBSD 14.x IS SLOW:
16af3993c9SLi-Wen Hsu	FreeBSD 14.x has many debugging features turned on, in both the kernel
17456b5dd8SWarner Losh	and userland.  These features attempt to detect incorrect use of
18456b5dd8SWarner Losh	system primitives, and encourage loud failure through extra sanity
19456b5dd8SWarner Losh	checking and fail stop semantics.  They also substantially impact
20456b5dd8SWarner Losh	system performance.  If you want to do performance measurement,
21456b5dd8SWarner Losh	benchmarking, and optimization, you'll want to turn them off.  This
22456b5dd8SWarner Losh	includes various WITNESS- related kernel options, INVARIANTS, malloc
23456b5dd8SWarner Losh	debugging flags in userland, and various verbose features in the
24456b5dd8SWarner Losh	kernel.  Many developers choose to disable these features on build
2599e449f2SJason Evans	machines to maximize performance.  (To completely disable malloc
267d4374f6SDimitry Andric	debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild
277d4374f6SDimitry Andric	world, or to merely disable the most expensive debugging functionality
287d4374f6SDimitry Andric	at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".)

30*e2650af1SStefan Eßer20211230:
31*e2650af1SStefan Eßer	The macros provided for the manipulation of CPU sets (e.g. CPU_AND)
32*e2650af1SStefan Eßer	have been modified to take 2 source arguments instead of only 1.
33*e2650af1SStefan Eßer	Externally maintained sources that use these macros will have to
34*e2650af1SStefan Eßer	be adapted. The FreeBSD version has been bumped to 1400046 to
35*e2650af1SStefan Eßer	reflect this change.
36*e2650af1SStefan Eßer
37dd55767bSWarner Losh20211214:
38dd55767bSWarner Losh	A number of the kernel include files are able to be included by
39dd55767bSWarner Losh	themselves.  A test has been added to buildworld to enforce this.
40dd55767bSWarner Losh
41b8cacb38SWarner Losh20211209:
42b8cacb38SWarner Losh	Remove mips as a recognized target. This starts the decommissioning of
43b8cacb38SWarner Losh	mips support in FreeBSD. mips related items will be removed wholesale in
44b8cacb38SWarner Losh	the coming days and weeks.
45b8cacb38SWarner Losh
4656e4bee1SWarner Losh	This broke the NO_CLEAN build for some people. Either do a clean build
4756e4bee1SWarner Losh	or touch
4856e4bee1SWarner Losh		lib/clang/include/llvm/Config/Targets.def
4956e4bee1SWarner Losh		lib/clang/include/llvm/Config/AsmParsers.def

54b8d60729SRandall Stewart20211110:
55d6953863SRandall Stewart	Commit b8d60729deef changed the TCP congestion control framework so
56b8d60729SRandall Stewart	that any of the included congestion control modules could be
57b8d60729SRandall Stewart	the single module built into the kernel. Previously newreno
58b8d60729SRandall Stewart	was automatically built in through direct reference. Has of
59b8d60729SRandall Stewart	this commit you are required to declare at least one congestion
60b8d60729SRandall Stewart	control module (e.g. 'options CC_NEWRENO') and to also delcare a
61b8d60729SRandall Stewart	default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\").
62b8d60729SRandall Stewart	The GENERIC configuation includes CC_NEWRENO and defines newreno
63b8d60729SRandall Stewart	as the default. If no congestion control option is built into the
64b8d60729SRandall Stewart	kernel and you are including networking, the kernel compile will
65b8d60729SRandall Stewart	fail. Also if no default is declared the kernel compile will fail.
66b8d60729SRandall Stewart
6767301655SWarner Losh20211118:
6867301655SWarner Losh	Mips has been removed from universe builds. It will be removed from the
6967301655SWarner Losh	tree shortly.
7067301655SWarner Losh
7125b0021dSRick Macklem20211106:
7225b0021dSRick Macklem	Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE.
7325b0021dSRick Macklem	The NFS modules must be rebuilt from sources and any out
7425b0021dSRick Macklem	of tree file systems that implement their own VOP_ALLOCATE
7525b0021dSRick Macklem	may need to be modified.
7625b0021dSRick Macklem
776aae3517SGleb Smirnoff20211022:
786aae3517SGleb Smirnoff	The synchronous PPP kernel driver sppp(4) has been removed.
796aae3517SGleb Smirnoff	The cp(4) and ce(4) drivers are now always compiled with netgraph(4)
806aae3517SGleb Smirnoff	support, formerly enabled by NETGRAPH_CRONYX option.
816aae3517SGleb Smirnoff
82d410b585SBaptiste Daroussin20211020:
836ae38ab4SBaptiste Daroussin	sh(1) is now the default shell for the root user.  To force root to use
84d410b585SBaptiste Daroussin	the csh shell, please run the following command as root:
85d410b585SBaptiste Daroussin
866ae38ab4SBaptiste Daroussin	# chsh -s csh
87d410b585SBaptiste Daroussin
8816f1ee11SBaptiste Daroussin20211004:
8916f1ee11SBaptiste Daroussin	Ncurses distribution has been split between libtinfow and libncurses
9016f1ee11SBaptiste Daroussin	with libncurses.so becoming a linker (ld) script to seamlessly link
9116f1ee11SBaptiste Daroussin	to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect
9216f1ee11SBaptiste Daroussin	this change.
9316f1ee11SBaptiste Daroussin
949cce0ef9SKristof Provost20210923:
959cce0ef9SKristof Provost	As of commit 8160a0f62be6, the dummynet module no longer depends on the
969cce0ef9SKristof Provost	ipfw module. Dummynet can now be used by pf as well as ipfw. As such
979cce0ef9SKristof Provost	users who relied on this dependency may need to include ipfw in the
989cce0ef9SKristof Provost	list of modules to load on their systems.
999cce0ef9SKristof Provost
1009cce0ef9SKristof Provost20210922:
1010e94a306SHans Petter Selasky	As of commit 903873ce1560, the mixer(8) utility has got a slightly
10290f6610bSHans Petter Selasky	new syntax. Please refer to the mixer(8) manual page for more
1038bc5971bSHans Petter Selasky	information. The old mixer utility can be installed from ports:
1048bc5971bSHans Petter Selasky	audio/freebsd-13-mixer
1050e94a306SHans Petter Selasky
106ae87a08cSRick Macklem20210911:
107ae87a08cSRick Macklem	As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has
108ae87a08cSRick Macklem	been deleted from the nfscommon.ko.  As such, nfsd.ko must be built
109ae87a08cSRick Macklem	from up to date sources to avoid an undefined reference when
110ae87a08cSRick Macklem	being loaded.
111ae87a08cSRick Macklem
112671a35b1SJohn Baldwin20210817:
113671a35b1SJohn Baldwin	As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS
114671a35b1SJohn Baldwin	by default.  Users can enable kernel TLS via the "KTLS" SSL
115671a35b1SJohn Baldwin	option.  This can be enabled globally by using a custom
116671a35b1SJohn Baldwin	OpenSSL config file via OPENSSL_CONF or via an
117671a35b1SJohn Baldwin	application-specific configuration option for applications
118671a35b1SJohn Baldwin	which permit setting SSL options via SSL_CONF_cmd(3).
119671a35b1SJohn Baldwin
120a3ff18e2SRick Macklem20210811:
121a3ff18e2SRick Macklem	Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS
122a3ff18e2SRick Macklem	modules. Therefore, all need to be rebuilt from sources.
123a3ff18e2SRick Macklem
12434129003SKristof Provost20210730:
12534129003SKristof Provost	Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl.
12634129003SKristof Provost	As of be70c7a50d32 it is no longer used by userspace, but it does mean
12734129003SKristof Provost	users may not be able to enumerate pf states if they update the kernel
128a191b401SKristof Provost	past b69019c14cd8 without first updating userspace past be70c7a50d32.
12934129003SKristof Provost
130728958fbSKristof Provost20210729:
131728958fbSKristof Provost	As of commit 01ad0c007964 if_bridge member interfaces can no longer
132728958fbSKristof Provost	change their MTU. Changing the MTU of the bridge itself will change the
133728958fbSKristof Provost	MTU on all member interfaces instead.
134728958fbSKristof Provost
1357fa21b6dSRick Macklem20210716:
1367fa21b6dSRick Macklem	Commit ee29e6f31111 changed the internal KAPI between the nfscommon
1377fa21b6dSRick Macklem	and nfsd modules. Therefore, both need to be rebuilt from sources.
1387fa21b6dSRick Macklem	Bump __FreeBSD_version to 1400026 for this KAPI change.
1397fa21b6dSRick Macklem
1405ede4fc0SWarner Losh20210715:
1415ede4fc0SWarner Losh	The 20210707 awk update brought in a change in behavior. This has
1425ede4fc0SWarner Losh	been corrected as of d4d252c49976. Between these dates, if you
1435ede4fc0SWarner Losh	installed a new awk binary, you may not be able to build a new
1445ede4fc0SWarner Losh	kernel because the change in behavior affected the genoffset
1455ede4fc0SWarner Losh	script used to build the kernel. If you did update, the fix is
1465ede4fc0SWarner Losh	to update your sources past the above hash and do
1475ede4fc0SWarner Losh		% cd usr.bin/awk
1485ede4fc0SWarner Losh		% make clean all
1495ede4fc0SWarner Losh		% sudo -E make install
1505ede4fc0SWarner Losh	to enable building kernels again.
1515ede4fc0SWarner Losh
152bd597b81SRick Macklem20210708:
153bd597b81SRick Macklem	Commit 1e0a518d6548 changed the internal KAPI between the NFS
154bd597b81SRick Macklem	modules. They all need to be rebuilt from sources.  I did not
155bd597b81SRick Macklem	bump __FreeBSD_version, since it was bumped recently.
156bd597b81SRick Macklem
1573f7b2317SWarner Losh20210707:
158a65fe39dSWarner Losh	awk has been updated to the latest one-true-awk version 20210215.
1593f7b2317SWarner Losh	This contains a number of minor bug fixes.
1603f7b2317SWarner Losh
161b49ba74dSRick Macklem20210624:
162b49ba74dSRick Macklem	The NFSv4 client now uses the highest minor version of NFSv4
163b49ba74dSRick Macklem	supported by the NFSv4 server by default instead of minor version 0,
164b49ba74dSRick Macklem	for NFSv4 mounts.
165b49ba74dSRick Macklem	The "minorversion" mount option may be used to override this default.
166b49ba74dSRick Macklem
16741dfd8bdSBjoern A. Zeeb20210618:
16841dfd8bdSBjoern A. Zeeb	Bump __FreeBSD_version to 1400024 for LinuxKPI changes.
169800e82d1SMaigurs Stalidzans	Most notably netdev.h can change now as the (last) dependencies
17041dfd8bdSBjoern A. Zeeb	(mlx4/ofed) are now using struct ifnet directly, but also for PCI
17141dfd8bdSBjoern A. Zeeb	additions and others.
17241dfd8bdSBjoern A. Zeeb
17341dfd8bdSBjoern A. Zeeb20210618:
17464e6e1e4SCeri Davies	The directory "blacklisted" under /usr/share/certs/ has been
17564e6e1e4SCeri Davies	renamed to "untrusted".
17664e6e1e4SCeri Davies
1775860696eSRick Macklem20210611:
1787cf9caf2SWarner Losh	svnlite has been removed from base. Should you need svn for any reason
1797cf9caf2SWarner Losh	please install the svn package or port.
1807cf9caf2SWarner Losh
1817cf9caf2SWarner Losh20210611:
1825860696eSRick Macklem	Commit e1a907a25cfa changed the internal KAPI between the krpc
1835860696eSRick Macklem	and nfsserver.  As such, both modules must be rebuilt from
1845860696eSRick Macklem	sources.  Bump __FreeBSD_version to 1400022.
1855860696eSRick Macklem
1867cf9caf2SWarner Losh20210610:
1877cf9caf2SWarner Losh	The an(4) driver has been removed from FreeBSD.
1887cf9caf2SWarner Losh
189b3823943SWarner Losh20210608:
190f530cce5SEd Maste	The vendor/openzfs branch was renamed to vendor/openzfs/legacy to
191b3823943SWarner Losh	start tracking OpenZFS upstream more closely. Please see
192b3823943SWarner Loshhttps://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html
193b3823943SWarner Losh	for details on how to correct any errors that might result. The
194b3823943SWarner Losh	short version is that you need to remove the old branch locally:
195b3823943SWarner Losh	    git update-ref -d refs/remotes/freebsd/vendor/openzfs
196b3823943SWarner Losh	(assuming your upstream origin is named 'freebsd').
197b3823943SWarner Losh
198d72cd275SBjoern A. Zeeb20210525:
199d72cd275SBjoern A. Zeeb	Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI
200d72cd275SBjoern A. Zeeb	which break drm-kmod.  In addition various other additions where
201d72cd275SBjoern A. Zeeb	comitted. Bump __FreeBSD_version to 1400015 to be able to detect this.
202d72cd275SBjoern A. Zeeb
2031c2ab28fSEmmanuel Vadot20210513:
2041c2ab28fSEmmanuel Vadot	Commit ca179c4d74f2 changed the package in which the OpenSSL
2051c2ab28fSEmmanuel Vadot	libraries and utilities are packaged.
20628ce2012SEmmanuel Vadot	It is recommended for pkgbase user to do:
2071c2ab28fSEmmanuel Vadot	pkg install -f FreeBSD-openssl
2081c2ab28fSEmmanuel Vadot	before pkg upgrade otherwise some dependencies might not be met
2091c2ab28fSEmmanuel Vadot	and pkg will stop working as libssl will not be present anymore
2101c2ab28fSEmmanuel Vadot	on the system.
2111c2ab28fSEmmanuel Vadot
21201bad87aSRick Macklem20210426:
21301bad87aSRick Macklem	Commit 875977314881 changed the internal KAPI between
21401bad87aSRick Macklem	the nfsd and nfscommon modules.  As such these modules
21501bad87aSRick Macklem	need to be rebuilt from sources.
21601bad87aSRick Macklem	Without this patch in your NFSv4.1/4.2 server, enabling
21701bad87aSRick Macklem	delegations by setting vfs.nfsd.issue_delegations non-zero
21801bad87aSRick Macklem	is not recommended.
21901bad87aSRick Macklem
22068b7d9b5SRick Macklem20210411:
22168b7d9b5SRick Macklem	Commit 7763814fc9c2 changed the internal KAPI between
22268b7d9b5SRick Macklem	the krpc and NFS.  As such, the krpc, nfscommon and
22368b7d9b5SRick Macklem	nfscl modules must all be rebuilt from sources.
224d647d0d4SRick Macklem	Without this patch, NFSv4.1/4.2 mounts should not
225d647d0d4SRick Macklem	be done with the nfscbd(8) daemon running, to avoid
226d647d0d4SRick Macklem	needing a working back channel for server->client RPCs.
22768b7d9b5SRick Macklem
2282b98ea2eSRick Macklem20210330:
2292b98ea2eSRick Macklem	Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it
2302b98ea2eSRick Macklem	handles binding of the back channel as required by RFC5661.
2312b98ea2eSRick Macklem	Until this patch is in your server, avoid use of the "nconnects"
2322b98ea2eSRick Macklem	mount option for Linux NFSv4.1/4.2 mounts.
2332b98ea2eSRick Macklem
234ba7ede0bSEd Maste20210225:
235ba7ede0bSEd Maste	For 64-bit architectures the base system is now built with Position
236ba7ede0bSEd Maste	Independent Executable (PIE) support enabled by default.  It may be
237ba7ede0bSEd Maste	disabled using the WITHOUT_PIE knob.  A clean build is required.
238ba7ede0bSEd Maste
239d386f3a3SBjoern A. Zeeb20210128:
240d386f3a3SBjoern A. Zeeb	Various LinuxKPI functionality was added which conflicts with DRM.
241d386f3a3SBjoern A. Zeeb	Please update your drm-kmod port to after the __FreeBSD_verison 1400003
242d386f3a3SBjoern A. Zeeb	update.
243d386f3a3SBjoern A. Zeeb
244429c7d1aSWarner Losh20210108:
245429c7d1aSWarner Losh	PC Card attachments for all devices have been removed. In the case of
246429c7d1aSWarner Losh	wi and cmx, the entire drivers were removed because they were only
247429c7d1aSWarner Losh	PC Card devices. FreeBSD_version 1300134 should be used for this
248429c7d1aSWarner Losh	since it was bumped so recently.
249429c7d1aSWarner Losh
25081098ca8SVladimir Kondratyev20210107:
251a84b0e94SVladimir Kondratyev	Transport-independent parts of HID support have been split off the USB
252a84b0e94SVladimir Kondratyev	code in to separate subsystem.  Kernel configs which include one of
253a84b0e94SVladimir Kondratyev	ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
254a84b0e94SVladimir Kondratyev	be updated with adding of "device hid" line.
255a84b0e94SVladimir Kondratyev
256009c1100SBaptiste Daroussin20210105:
257bed70f83SBaptiste Daroussin	ncurses installation has been modified to only keep the widechar
258bed70f83SBaptiste Daroussin	enabled version.  Incremental build is broken for that change, so it
259bed70f83SBaptiste Daroussin	requires a clean build.
260bed70f83SBaptiste Daroussin
261878d5341SWarner Losh20201223:
262878d5341SWarner Losh	The FreeBSD project has migrated from Subversion to Git. Temporary

267228e2087SPedro F. Giffuni20201216:
268228e2087SPedro F. Giffuni	The services database has been updated to cover more of the basic
269228e2087SPedro F. Giffuni	services expected in a modern system. The database is big enough
270228e2087SPedro F. Giffuni	that it will cause issues in mergemaster in Releases previous to
271228e2087SPedro F. Giffuni	12.2 and 11.3, or in very old current systems from before r358154.
272228e2087SPedro F. Giffuni
2731c0ea326SEd Maste20201215:
2741c0ea326SEd Maste	Obsolete in-tree GDB 6.1.1 has been removed.  GDB (including kgdb)
2751c0ea326SEd Maste	may be installed from ports or packages.
2761c0ea326SEd Maste

2877afa1a75SStefan Eßer	The internal pre-processor in the calendar(1) program has been
2887afa1a75SStefan Eßer	extended to support more C pre-processor commands (e.g. #ifdef, #else,
2897afa1a75SStefan Eßer	and #undef) and to detect unbalanced conditional statements.
2907afa1a75SStefan Eßer	Error messages have been extended to include the filename and line

293a97cfe08SStefan Eßer20201026:
294d20d6550SWarner Losh	All the data files for the calendar(1) program, except calendar.freebsd,
295d20d6550SWarner Losh	have been moved to the deskutils/calendar-data port, much like the
296d20d6550SWarner Losh	jewish calendar entries were moved to deskutils/hebcal years ago. After
297d20d6550SWarner Losh	make delete-old-files, you need to install it to retain full
298d20d6550SWarner Losh	functionality. calendar(1) will issue a reminder for files it can't

3155db7b015SMatt Macy	OpenZFS support has been integrated. Do not upgrade root pools until
3165db7b015SMatt Macy	the loader is updated to support zstd. Furthermore, we caution against
3175db7b015SMatt Macy	'zpool upgrade' for the next few weeks. The change should be transparent

320d0fba0c5SWarner Losh	Not all "NO_CLEAN" build scenarios work across these changes. Many
321d0fba0c5SWarner Losh	scenarios have been tested and fixed, but rebuilding kernels without

323d0fba0c5SWarner Losh
324f03478b1SWarner Losh	The ZFS cache file has moved from /boot to /etc to match the OpenZFS
325de209fe1SRyan Moeller	upstream default. A fallback to /boot has been added for mountroot.
326de209fe1SRyan Moeller
327de209fe1SRyan Moeller	Pool auto import behavior at boot has been moved from the kernel module
328de209fe1SRyan Moeller	to an explicit "zpool import -a" in one of the rc scripts enabled by
329de209fe1SRyan Moeller	zfs_enable=YES. This means your non-root zpools won't auto import until

33871bba112SRick Macklem20200821:
33971bba112SRick Macklem	r362275 changed the internal API between the kernel RPC and the

35833176cdcSWarner Losh20200807:
35933176cdcSWarner Losh	Makefile.inc has been updated to work around the issue documented in
36033176cdcSWarner Losh	20200729. It was a case where the optimization of using symbolic links
36133176cdcSWarner Losh	to point to binaries created a situation where we'd run new binaries
36233176cdcSWarner Losh	with old libraries starting midway through the installworld process.

364d2090a40SKyle Evans20200729:
365d2090a40SKyle Evans	r363679 has redefined some undefined behavior in regcomp(3); notably,
366d2090a40SKyle Evans	extraneous escapes of most ordinary characters will no longer be
367d2090a40SKyle Evans	accepted.  An exp-run has identified all of the problems with this in
368d2090a40SKyle Evans	ports, but other non-ports software may need extra escapes removed to
369d2090a40SKyle Evans	continue to function.
370d2090a40SKyle Evans
371d6391a26SKyle Evans	Because of this change, installworld may encounter the following error

376c2caa342SStefan Eßer20200627:
377dee0d87cSWarner Losh	A new implementation of bc and dc has been imported in r362681. This
378c2caa342SStefan Eßer	implementation corrects non-conformant behavior of the previous bc
379c2caa342SStefan Eßer	and adds GNU bc compatible options. It offers a number of extensions,
380c2caa342SStefan Eßer	is much faster on large values, and has support for message catalogs
381c2caa342SStefan Eßer	(a number of languages are already supported, contributions of further

389be8f8ca2SRick Macklem20200613:
390be8f8ca2SRick Macklem	r362158 changed the arguments for VFS_CHECKEXP().  As such, any
391be8f8ca2SRick Macklem	out of tree file systems need to be modified and rebuilt.
392be8f8ca2SRick Macklem	Also, any file systems that are modules must be rebuilt.

6443782136fSConrad Meyer20190418:
6453782136fSConrad Meyer	The following knobs have been added related to tradeoffs between
6463782136fSConrad Meyer	safe use of the random device and availability in the absence of
6473782136fSConrad Meyer	entropy:

6493782136fSConrad Meyer	kern.random.initial_seeding.bypass_before_seeding: tunable; set
6503782136fSConrad Meyer	non-zero to bypass the random device prior to seeding, or zero to
6513782136fSConrad Meyer	block random requests until the random device is initially seeded.
6523782136fSConrad Meyer	For now, set to 1 (unsafe) by default to restore pre-r346250 boot
6533782136fSConrad Meyer	availability properties.
6543782136fSConrad Meyer
6553782136fSConrad Meyer	kern.random.initial_seeding.read_random_bypassed_before_seeding:
6563782136fSConrad Meyer	read-only diagnostic sysctl that is set when bypass is enabled and
6573782136fSConrad Meyer	read_random(9) is bypassed, to enable programmatic handling of this
6583782136fSConrad Meyer	initial condition, if desired.
6593782136fSConrad Meyer
6603782136fSConrad Meyer	kern.random.initial_seeding.arc4random_bypassed_before_seeding:

668f3d2512dSConrad Meyer20190416:
669f3d2512dSConrad Meyer	The loadable random module KPI has changed; the random_infra_init()
670f3d2512dSConrad Meyer	routine now requires a 3rd function pointer for a bool (*)(void)

71783a41dd0SRebecca Cran20181230:
71883a41dd0SRebecca Cran	r342635 changes the way efibootmgr(8) works by requiring users to add
71983a41dd0SRebecca Cran	the -b (bootnum) parameter for commands where the bootnum was previously
72083a41dd0SRebecca Cran	specified with each option. For example 'efibootmgr -B 0001' is now

723d493fe42SRick Macklem20181220:
724d493fe42SRick Macklem	r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
725d493fe42SRick Macklem	in the same as it is applied to NFSv2 and 3.  This implies that NFSv4
726d493fe42SRick Macklem	servers that have vfs.nfsd.nfs_privport set will only allow mounts
727857cde69SMaigurs Stalidzans	from clients using a reserved port. Since both the FreeBSD and Linux
728857cde69SMaigurs Stalidzans	NFSv4 clients use reserved ports by default, this should not affect

779468002c5SWarner Losh20181015:
780468002c5SWarner Losh	Ports for the DRM modules have been simplified. Now, amd64 users should
781468002c5SWarner Losh	just install the drm-kmod port. All others should install
782468002c5SWarner Losh	drm-legacy-kmod.
783468002c5SWarner Losh
784468002c5SWarner Losh	Graphics hardware that's newer than about 2010 usually works with
785468002c5SWarner Losh	drm-kmod.  For hardware older than 2013, however, some users will need
786468002c5SWarner Losh	to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
787468002c5SWarner Losh	than 2008 usually only works in drm-legacy-kmod. The graphics team can
788468002c5SWarner Losh	only commit to hardware made since 2013 due to the complexity of the
789468002c5SWarner Losh	market and difficulty to test all the older cards effectively. If you
790468002c5SWarner Losh	have hardware supported by drm-kmod, you are strongly encouraged to use
791468002c5SWarner Losh	that as you will get better support.
792468002c5SWarner Losh
793468002c5SWarner Losh	Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
794468002c5SWarner Losh	elsewhere, the drm and drm2 modules will be eliminated from the src base
795274cfcd7SWarner Losh	soon (with a limited exception for arm). Please update to the package

797468002c5SWarner Losh
798468002c5SWarner Losh	Generally, anybody using the drm*-kmod packages should add
799468002c5SWarner Losh	WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty

8248ac2f3baSKevin Bowling20181002:
8258ac2f3baSKevin Bowling	The cam(4) based nda(4) driver will be used over nvd(4) by default on
8268ac2f3baSKevin Bowling	powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or
8278ac2f3baSKevin Bowling	loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing
8288ac2f3baSKevin Bowling	driver.  Make sure to edit /boot/etc/kboot.conf and fstab to use the
8298ac2f3baSKevin Bowling	nda device name.
8308ac2f3baSKevin Bowling
8318d66f7beSEd Maste20180913:
8328d66f7beSEd Maste	Reproducible build mode is now on by default, in preparation for
8338d66f7beSEd Maste	FreeBSD 12.0.  This eliminates build metadata such as the user,
8348d66f7beSEd Maste	host, and time from the kernel (and uname), unless the working tree
8358d66f7beSEd Maste	corresponds to a modified checkout from a version control system.
8368d66f7beSEd Maste	The previous behavior can be obtained by setting the /etc/src.conf
8378d66f7beSEd Maste	knob WITHOUT_REPRODUCIBLE_BUILD.
8388d66f7beSEd Maste
83919fa89e9SMark Murray20180826:
84019fa89e9SMark Murray	The Yarrow CSPRNG has been removed from the kernel as it has not been
84119fa89e9SMark Murray	supported by its designers since at least 2003. Fortuna has been the
84219fa89e9SMark Murray	default since FreeBSD-11.
84319fa89e9SMark Murray
8440fb707ecSWarner Losh20180822:
8450fb707ecSWarner Losh	devctl freeze/thaw have gone into the tree, the rc scripts have been
84684b9dfe4SWarner Losh	updated to use them and devmatch has been changed.  You should update
84784b9dfe4SWarner Losh	kernel, userland and rc scripts all at the same time.
84884b9dfe4SWarner Losh
849f9f8ac94SKyle Evans20180818:
850f9f8ac94SKyle Evans	The default interpreter has been switched from 4th to Lua.
851f9f8ac94SKyle Evans	LOADER_DEFAULT_INTERP, documented in build(7), will override the default
852f9f8ac94SKyle Evans	interpreter.  If you have custom FORTH code you will need to set
853f9f8ac94SKyle Evans	LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
854f9f8ac94SKyle Evans	src.conf for the build.  This will create default hard links between
855f9f8ac94SKyle Evans	loader and loader_4th instead of loader and loader_lua, the new default.
856f9f8ac94SKyle Evans	If you are using UEFI it will create the proper hard link to loader.efi.
857f9f8ac94SKyle Evans
858295506bfSWarner Losh	bhyve uses userboot.so. It remains 4th-only until some issues are solved
859295506bfSWarner Losh	regarding coexisting with multiple versions of FreeBSD are resolved.
860295506bfSWarner Losh
86172ad696aSKyle Evans20180815:
86272ad696aSKyle Evans	ls(1) now respects the COLORTERM environment variable used in other
86372ad696aSKyle Evans	systems and software to indicate that a colored terminal is both
86472ad696aSKyle Evans	supported and desired.  If ls(1) is suddenly emitting colors, they may
865e10ba800SKyle Evans	be disabled again by either removing the unwanted COLORTERM from your
866e10ba800SKyle Evans	environment, or using `ls --color=never`.  The ls(1) specific CLICOLOR
867e10ba800SKyle Evans	may not be observed in a future release.
86872ad696aSKyle Evans
86947cc9ee1SAlan Somers20180808:
87047cc9ee1SAlan Somers	The default pager for most commands has been changed to "less".  To
87147cc9ee1SAlan Somers	restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
87247cc9ee1SAlan Somers	your environment.
87347cc9ee1SAlan Somers
874b5988450SRavi Pokala20180731:
875b5988450SRavi Pokala	The jedec_ts(4) driver has been removed. A superset of its functionality
876b5988450SRavi Pokala	is available in the jedec_dimm(4) driver, and the manpage for that
877b5988450SRavi Pokala	driver includes migration instructions. If you have "device jedec_ts"
878b5988450SRavi Pokala	in your kernel configuration file, it must be removed.
879b5988450SRavi Pokala
880164138e7SKyle Evans20180730:
881164138e7SKyle Evans	amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
882dfa6eec2SKyle Evans	This should have no effect if the kernel is booted via BIOS/legacy boot.
8831ddc8a8eSKyle Evans	EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
884164138e7SKyle Evans	has a buggy firmware that prevents a successful boot due to use of
885164138e7SKyle Evans	runtime services.
886164138e7SKyle Evans
887411e4219SWarner Losh20180727:
888411e4219SWarner Losh	Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale
889411e4219SWarner Losh	support has been removed from the tree. These ports were
890411e4219SWarner Losh	obsolete and/or known to be broken for many years.
891411e4219SWarner Losh
892b43c6042SWarner Losh20180723:
893b43c6042SWarner Losh	loader.efi has been augmented to participate more fully in the
894663472dfSWarner Losh	UEFI boot manager protocol. loader.efi will now look at the
895663472dfSWarner Losh	BootXXXX environment variable to determine if a specific kernel
896663472dfSWarner Losh	or root partition was specified. XXXX is derived from BootCurrent.
897663472dfSWarner Losh	efibootmgr(8) manages these standard UEFI variables.
898b43c6042SWarner Losh
899d397afa3SWarner Losh20180720:
900d397afa3SWarner Losh	zfsloader's functionality has now been folded into loader.
9015f9d7aafSEd Maste	zfsloader is no longer necessary once you've updated your
9023b741022SWarner Losh	boot blocks. For a transition period, we will install a
9033b741022SWarner Losh	hardlink for zfsloader to loader to allow a smooth transition
9043b741022SWarner Losh	until the boot blocks can be updated (hard link because old
9053b741022SWarner Losh	zfs boot blocks don't understand symlinks).
906d397afa3SWarner Losh
907d0e46652SIan Lepore20180719:
908c59a544eSEmmanuel Vadot	ARM64 now have efifb support, if you want to have serial console
909c59a544eSEmmanuel Vadot	on your arm64 board when an screen is connected and the bootloader
910deb17a3bSWarner Losh	setup a frame buffer for us to use, just add :
911c59a544eSEmmanuel Vadot	boot_serial=YES
912c59a544eSEmmanuel Vadot	boot_multicons=YES
913c59a544eSEmmanuel Vadot	in /boot/loader.conf
914c59a544eSEmmanuel Vadot	For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
915c59a544eSEmmanuel Vadot	an screen connected as the firmware will setup a frame buffer are that
916c59a544eSEmmanuel Vadot	u-boot will expose as an EFI frame buffer.
917c59a544eSEmmanuel Vadot
918c59a544eSEmmanuel Vadot20180719:
919d0e46652SIan Lepore	New uid:gid added, ntpd:ntpd (123:123).  Be sure to run mergemaster
920d0e46652SIan Lepore	or take steps to update /etc/passwd before doing installworld on
9210d77d170SIan Lepore	existing systems.  Do not skip the "mergemaster -Fp" step before
9220d77d170SIan Lepore	installworld, as described in the update procedures near the bottom
9230d77d170SIan Lepore	of this document.  Also, rc.d/ntpd now starts ntpd(8) as user ntpd
924d0e46652SIan Lepore	if the new mac_ntpd(4) policy is available, unless ntpd_flags or
925d0e46652SIan Lepore	the ntp config file contain options that change file/dir locations.
926d0e46652SIan Lepore	When such options (e.g., "statsdir" or "crypto") are used, ntpd can
927d0e46652SIan Lepore	still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
928d0e46652SIan Lepore	taking steps to ensure that all required files/dirs are accessible
929d0e46652SIan Lepore	by the ntpd user.
930d0e46652SIan Lepore
931dbe8ed38SWarner Losh20180717:
932dbe8ed38SWarner Losh	Big endian arm support has been removed.
933dbe8ed38SWarner Losh
93444314c35SKyle Evans20180711:
93544314c35SKyle Evans	The static environment setup in kernel configs is no longer mutually
93644314c35SKyle Evans	exclusive with the loader(8) environment by default.  In order to
93744314c35SKyle Evans	restore the previous default behavior of disabling the loader(8)
93844314c35SKyle Evans	environment if a static environment is present, you must specify
93944314c35SKyle Evans	loader_env.disabled=1 in the static environment.
94044314c35SKyle Evans
941f38b68aeSBrooks Davis20180705:
942f38b68aeSBrooks Davis	The ABI of syscalls used by management tools like sockstat and
943f38b68aeSBrooks Davis	netstat has been broken to allow 32-bit binaries to work on
944f38b68aeSBrooks Davis	64-bit kernels without modification.  These programs will need
945f38b68aeSBrooks Davis	to match the kernel in order to function.  External programs may
946f38b68aeSBrooks Davis	require minor modifications to accommodate a change of type in
947f38b68aeSBrooks Davis	structures from pointers to 64-bit virtual addresses.
948f38b68aeSBrooks Davis
949f4b36404SMatt Macy20180702:
950f4b36404SMatt Macy	On i386 and amd64 atomics are now inlined. Out of tree modules using
951f4b36404SMatt Macy	atomics will need to be rebuilt.
952f4b36404SMatt Macy
9530dea6e3cSMariusz Zaborski20180701:
9540dea6e3cSMariusz Zaborski	The '%I' format in the kern.corefile sysctl limits the number of
9550dea6e3cSMariusz Zaborski	core files that a process can generate to the number stored in the
9560dea6e3cSMariusz Zaborski	debug.ncores sysctl. The '%I' format is replaced by the single digit
9570dea6e3cSMariusz Zaborski	index. Previously, if all indexes were taken the kernel would overwrite
9580dea6e3cSMariusz Zaborski	only a core file with the highest index in a filename.
9590dea6e3cSMariusz Zaborski	Currently the system will create a new core file if there is a free
9600dea6e3cSMariusz Zaborski	index or if all slots are taken it will overwrite the oldest one.

96255458465SDimitry Andric20180630:
96355458465SDimitry Andric	Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to
96455458465SDimitry Andric	6.0.1.  Please see the 20141231 entry below for information about

9682fd8cef4SWarner Losh20180628:
9692fd8cef4SWarner Losh	r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
9702fd8cef4SWarner Losh	needed to be changed to work with it. This change was made with r335763
971274cfcd7SWarner Losh	and requires a mergemaster / etcupdate / etc to update the installed
972274cfcd7SWarner Losh	file.
9732fd8cef4SWarner Losh
974fa986e33SRick Macklem20180612:
975fa986e33SRick Macklem	r334930 changed the interface between the NFS modules, so they all
976fa986e33SRick Macklem	need to be rebuilt.  r335018 did a __FreeBSD_version bump for this.
977fa986e33SRick Macklem
9780bf7cdd5SWarner Losh20180530:
9796f282e72SEd Maste	As of r334391 lld is the default amd64 system linker; it is installed
9806f282e72SEd Maste	as /usr/bin/ld.  Kernel build workarounds (see 20180510 entry) are no
9816f282e72SEd Maste	longer necessary.
9826f282e72SEd Maste
9836f282e72SEd Maste20180530:
9840bf7cdd5SWarner Losh	The kernel / userland interface for devinfo changed, so you'll
9850bf7cdd5SWarner Losh	need a new kernel and userland as a pair for it to work (rebuilding
9860bf7cdd5SWarner Losh	lib/libdevinfo is all that's required). devinfo and devmatch will
9870bf7cdd5SWarner Losh	not work, but everything else will when there's a mismatch.
9880bf7cdd5SWarner Losh
9897e1a13f4SMatt Macy20180523:
9907e1a13f4SMatt Macy	The on-disk format for hwpmc callchain records has changed to include
9917e1a13f4SMatt Macy	threadid corresponding to a given record. This changes the field offsets
9927e1a13f4SMatt Macy	and thus requires that libpmcstat be rebuilt before using a kernel
9937e1a13f4SMatt Macy	later than r334108.
9947e1a13f4SMatt Macy
9956f78fad3SSean Bruno20180517:
9966f78fad3SSean Bruno	The vxge(4) driver has been removed.  This driver was introduced into
9976f78fad3SSean Bruno	HEAD one week before the Exar left the Ethernet market and is not
9986f78fad3SSean Bruno	known to be used.  If you have device vxge in your kernel config file
9996f78fad3SSean Bruno	it must be removed.
10006f78fad3SSean Bruno
10016e258ed3SWarner Losh20180510:
1002eb8831b9SWarner Losh	The amd64 kernel now requires a ld that supports ifunc to produce a
1003eb8831b9SWarner Losh	working kernel, either lld or a newer binutils. lld is built by default
1004eb8831b9SWarner Losh	on amd64, and the 'buildkernel' target uses it automatically. However,
1005eb8831b9SWarner Losh	it is not the default linker, so building the kernel the traditional
1006eb8831b9SWarner Losh	way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
1007eb8831b9SWarner Losh	binutils port/package). lld will soon be default, and this requirement
1008eb8831b9SWarner Losh	will go away.
1009eb8831b9SWarner Losh
10106f282e72SEd Maste	NOTE: As of r334391 lld is the default system linker on amd64, and no
10116f282e72SEd Maste	workaround is necessary.
10126f282e72SEd Maste
101357b49365SSean Bruno20180508:
101457b49365SSean Bruno	The nxge(4) driver has been removed.  This driver was for PCI-X 10g
101582455a33SJens Schweikhardt	cards made by s2io/Neterion.  The company was acquired by Exar and
101657b49365SSean Bruno	no longer sells or supports Ethernet products.  If you have device
101757b49365SSean Bruno	nxge in your kernel config file it must be removed.
101857b49365SSean Bruno
1019ba3833a8SPhilip Paeps20180504:
1020ba3833a8SPhilip Paeps	The tz database (tzdb) has been updated to 2018e.  This version more
1021ba3833a8SPhilip Paeps	correctly models time stamps in time zones with negative DST such as
1022ba3833a8SPhilip Paeps	Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
1023ba3833a8SPhilip Paeps	Africa/Windhoek (1994/2017).  This does not affect the UT offsets, only
1024ba3833a8SPhilip Paeps	time zone abbreviations and the tm_isdst flag.
1025ba3833a8SPhilip Paeps
10262695c9c1SSean Bruno20180502:
10272695c9c1SSean Bruno	The ixgb(4) driver has been removed.  This driver was for an early and
10282695c9c1SSean Bruno	uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
10292695c9c1SSean Bruno	quickly shifted to the long lived ixgbe family.  If you have device
10302695c9c1SSean Bruno	ixgb in your kernel config file it must be removed.
10312695c9c1SSean Bruno
1032e6a376d1SEd Maste20180501:
1033e6a376d1SEd Maste	The lmc(4) driver has been removed.  This was a WAN interface
1034e6a376d1SEd Maste	card that was already reportedly rare in 2003, and had an ambiguous
1035e6a376d1SEd Maste	license.  If you have device lmc in your kernel config file it must
1036e6a376d1SEd Maste	be removed.
1037e6a376d1SEd Maste
10383a4fc8a8SBrooks Davis20180413:
10393a4fc8a8SBrooks Davis	Support for Arcnet networks has been removed.  If you have device
10403a4fc8a8SBrooks Davis	arcnet or device cm in your kernel config file they must be
10413a4fc8a8SBrooks Davis	removed.
10423a4fc8a8SBrooks Davis
10430437c8e3SBrooks Davis20180411:
10440437c8e3SBrooks Davis	Support for FDDI networks has been removed.  If you have device
10450437c8e3SBrooks Davis	fddi or device fpa in your kernel config file they must be
10460437c8e3SBrooks Davis	removed.
10470437c8e3SBrooks Davis
10488129693eSEd Schouten20180406:
10498129693eSEd Schouten	In addition to supporting RFC 3164 formatted messages, the
10508129693eSEd Schouten	syslogd(8) service is now capable of parsing RFC 5424 formatted
10518129693eSEd Schouten	log messages. The main benefit of using RFC 5424 is that clients
10528129693eSEd Schouten	may now send log messages with timestamps containing year numbers,
10538129693eSEd Schouten	microseconds and time zone offsets.
10548129693eSEd Schouten
10558129693eSEd Schouten	Similarly, the syslog(3) C library function has been altered to
10568129693eSEd Schouten	send RFC 5424 formatted messages to the local system logging
10578129693eSEd Schouten	daemon. On systems using syslogd(8), this change should have no
10588129693eSEd Schouten	negative impact, as long as syslogd(8) and the C library are
10598129693eSEd Schouten	updated at the same time. On systems using a different system
10608129693eSEd Schouten	logging daemon, it may be necessary to make configuration
10618129693eSEd Schouten	adjustments, depending on the software used.
10628129693eSEd Schouten
10638129693eSEd Schouten	When using syslog-ng, add the 'syslog-protocol' flag to local
10648129693eSEd Schouten	input sources to enable parsing of RFC 5424 formatted messages:
10658129693eSEd Schouten
10668129693eSEd Schouten		source src {
10678129693eSEd Schouten			unix-dgram("/var/run/log" flags(syslog-protocol));
10688129693eSEd Schouten		}
10698129693eSEd Schouten
10708129693eSEd Schouten	When using rsyslog, disable the 'SysSock.UseSpecialParser' option
10718129693eSEd Schouten	of the 'imuxsock' module to let messages be processed by the
10728129693eSEd Schouten	regular RFC 3164/5424 parsing pipeline:
10738129693eSEd Schouten
10748129693eSEd Schouten		module(load="imuxsock" SysSock.UseSpecialParser="off")
10758129693eSEd Schouten
10768129693eSEd Schouten	Do note that these changes only affect communication between local
10778129693eSEd Schouten	applications and syslogd(8). The format that syslogd(8) uses to
10788129693eSEd Schouten	store messages on disk or forward messages to other systems
10798129693eSEd Schouten	remains unchanged. syslogd(8) still uses RFC 3164 for these
10808129693eSEd Schouten	purposes. Options to customize this behaviour will be added in the
10818129693eSEd Schouten	future. Utilities that process log files stored in /var/log are
10828129693eSEd Schouten	thus expected to continue to function as before.
10838129693eSEd Schouten
10848129693eSEd Schouten	__FreeBSD_version has been incremented to 1200061 to denote this
10858129693eSEd Schouten	change.
10868129693eSEd Schouten
1087c53b0251SBrooks Davis20180328:
108869f0fecbSBrooks Davis	Support for token ring networks has been removed. If you
108969f0fecbSBrooks Davis	have "device token" in your kernel config you should remove
109069f0fecbSBrooks Davis	it. No device drivers supported token ring.
109169f0fecbSBrooks Davis
109272bf324cSBenno Rice20180323:
109372bf324cSBenno Rice	makefs was modified to be able to tag ISO9660 El Torito boot catalog
109472bf324cSBenno Rice	entries as EFI instead of overloading the i386 tag as done previously.
109572bf324cSBenno Rice	The amd64 mkisoimages.sh script used to build amd64 ISO images for

1367b149eba4SEd Maste	The "ino64" 64-bit inode project has been committed, which extends
1368dcfffd04SEd Maste	a number of types to 64 bits.  Upgrading in place requires care and
1369dcfffd04SEd Maste	adherence to the documented upgrade procedure.
1370dcfffd04SEd Maste
1371dcfffd04SEd Maste	If using a custom kernel configuration ensure that the
1372dcfffd04SEd Maste	COMPAT_FREEBSD11 option is included (as during the upgrade the
1373dcfffd04SEd Maste	system will be running the ino64 kernel with the existing world).
1374dcfffd04SEd Maste
1375dcfffd04SEd Maste	For the safest in-place upgrade begin by removing previous build
1376359d22d4SWarner Losh	artifacts via "rm -rf /usr/obj/*".  Then, carefully follow the full
1377359d22d4SWarner Losh	procedure documented below under the heading "To rebuild everything and
1378359d22d4SWarner Losh	install it on the current system."  Specifically, a reboot is required
1379359d22d4SWarner Losh	after installing the new kernel before installing world. While an
1380359d22d4SWarner Losh	installworld normally works by accident from multiuser after rebooting
1381359d22d4SWarner Losh	the proper kernel, there are many cases where this will fail across this
1382359d22d4SWarner Losh	upgrade and installworld from single user is required.

1384a25a1ff4SBrooks Davis20170424:
1385a25a1ff4SBrooks Davis	The NATM framework including the en(4), fatm(4), hatm(4), and
1386a25a1ff4SBrooks Davis	patm(4) devices has been removed.  Consumers should plan a
1387a25a1ff4SBrooks Davis	migration before the end-of-life date for FreeBSD 11.

1389a17665bcSBaptiste Daroussin20170420:
1390a17665bcSBaptiste Daroussin	GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1391a17665bcSBaptiste Daroussin	diff has not been implemented, if those are needed a newer version of
1392a17665bcSBaptiste Daroussin	GNU diff is available via the diffutils package under the gdiff name.

13945810e45bSCy Schubert20170413:
13955810e45bSCy Schubert	As of r316810 for ipfilter, keep frags is no longer assumed when
13965810e45bSCy Schubert	keep state is specified in a rule. r316810 aligns ipfilter with
13975810e45bSCy Schubert	documentation in man pages separating keep frags from keep state.
1398a3a09aefSJens Schweikhardt	This allows keep state to be specified without forcing keep frags
13995810e45bSCy Schubert	and allows keep frags to be specified independently of keep state.
14005810e45bSCy Schubert	To maintain previous behaviour, also specify keep frags with
14010cad3ecaSCy Schubert	keep state (as documented in ipf.conf.5).
14025810e45bSCy Schubert
14031bf5e133SEd Maste20170407:
14041bf5e133SEd Maste	arm64 builds now use the base system LLD 4.0.0 linker by default,
14051bf5e133SEd Maste	instead of requiring that the aarch64-binutils port or package be
14061bf5e133SEd Maste	installed. To continue using aarch64-binutils, set
14071bf5e133SEd Maste	CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin .

140928da7a25SBryan Drewery20170405:
141028da7a25SBryan Drewery	The UDP optimization in entry 20160818 that added the sysctl
141128da7a25SBryan Drewery	net.inet.udp.require_l2_bcast has been reverted.  L2 broadcast
141228da7a25SBryan Drewery	packets will no longer be treated as L3 broadcast packets.

14146ebc1b7bSSteven Hartland20170331:
14154d806fc6SSteven Hartland	Binds and sends to the loopback addresses, IPv6 and IPv4, will now
14166ebc1b7bSSteven Hartland	use any explicitly assigned loopback address available in the jail
14174d806fc6SSteven Hartland	instead of using the first assigned address of the jail.

14190458b265SEnji Cooper20170329:
14200458b265SEnji Cooper	The ctl.ko module no longer implements the iSCSI target frontend:
14210458b265SEnji Cooper	cfiscsi.ko does instead.
14220458b265SEnji Cooper
14230458b265SEnji Cooper	If building cfiscsi.ko as a kernel module, the module can be loaded
14240458b265SEnji Cooper	via one of the following methods:
14250458b265SEnji Cooper	- `cfiscsi_load="YES"` in loader.conf(5).
14260458b265SEnji Cooper	- Add `cfiscsi` to `$kld_list` in rc.conf(5).
14270458b265SEnji Cooper	- ctladm(8)/ctld(8), when compiled with iSCSI support
14280458b265SEnji Cooper	  (`WITH_ISCSI=yes` in src.conf(5))
14290458b265SEnji Cooper
14300458b265SEnji Cooper	Please see cfiscsi(4) for more details.

143272dec079SMarius Strobl20170316:
143372dec079SMarius Strobl	The mmcsd.ko module now additionally depends on geom_flashmap.ko.
143472dec079SMarius Strobl	Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
143572dec079SMarius Strobl	same source (previously, the dependency of mmcsd.ko on mmc.ko was
143672dec079SMarius Strobl	missing, but mmcsd.ko now will refuse to load if it is incompatible
143772dec079SMarius Strobl	with mmc.ko).

14396ed14738SAndrey V. Elsukov20170315:
14406ed14738SAndrey V. Elsukov	The syntax of ipfw(8) named states was changed to avoid ambiguity.
14416ed14738SAndrey V. Elsukov	If you have used named states in the firewall rules, you need to modify
14426ed14738SAndrey V. Elsukov	them after installworld and before rebooting. Now named states must
14436ed14738SAndrey V. Elsukov	be prefixed with colon.

14453bbe3f67SBaptiste Daroussin20170311:
1446f7c23774SEmmanuel Vadot	The old drm (sys/dev/drm/) drivers for i915 and radeon have been
1447f7c23774SEmmanuel Vadot	removed as the userland we provide cannot use them. The KMS version
1448a3a09aefSJens Schweikhardt	(sys/dev/drm2) supports the same hardware.

1455e9a0a054SAndriy Gapon20170221:
1456e9a0a054SAndriy Gapon	The code that provides support for ZFS .zfs/ directory functionality
1457e9a0a054SAndriy Gapon	has been reimplemented.  It's not possible now to create a snapshot
1458e9a0a054SAndriy Gapon	by mkdir under .zfs/snapshot/.  That should be the only user visible
1459e9a0a054SAndriy Gapon	change.

146118f447edSWarner Losh20170216:
146218f447edSWarner Losh	EISA bus support has been removed. The WITH_EISA option is no longer
146318f447edSWarner Losh	valid.
146418f447edSWarner Losh
146518f447edSWarner Losh20170215:

1468f52e4bdfSEd Maste20170127:
1469f52e4bdfSEd Maste	The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed
1470f52e4bdfSEd Maste	WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC.

1472062a4b8cSSean Bruno20170112:
1473062a4b8cSSean Bruno	The EM_MULTIQUEUE kernel configuration option is deprecated now that
1474062a4b8cSSean Bruno	the em(4) driver conforms to iflib specifications.
1475062a4b8cSSean Bruno
1476f2d6ace4SSean Bruno20170109:
1477f2d6ace4SSean Bruno	The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
1478f2d6ace4SSean Bruno	IFLIB.  If you have a custom kernel configuration that excludes em(4)
1479274cfcd7SWarner Losh	but you use igb(4), you need to re-add em(4) to your custom
1480274cfcd7SWarner Losh	configuration.

14924026b447SJustin Hibbits20161119:
14934026b447SJustin Hibbits	The layout of the pmap structure has changed for powerpc to put the pmap
14944026b447SJustin Hibbits	statistics at the front for all CPU variations.  libkvm(3) and all tools
14954026b447SJustin Hibbits	that link against it need to be recompiled.

1497448897d3SAndriy Gapon20161030:
1498448897d3SAndriy Gapon	isl(4) and cyapa(4) drivers now require a new driver,
1499448897d3SAndriy Gapon	chromebook_platform(4), to work properly on Chromebook-class hardware.
1500448897d3SAndriy Gapon	On other types of hardware the drivers may need to be configured using
1501448897d3SAndriy Gapon	device hints.  Please see the corresponding manual pages for details.

15032616dd0bSAndriy Voskoboinyk20161017:
15042616dd0bSAndriy Voskoboinyk	The urtwn(4) driver was merged into rtwn(4) and now consists of
15052616dd0bSAndriy Voskoboinyk	rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
15062616dd0bSAndriy Voskoboinyk	parts.
15072616dd0bSAndriy Voskoboinyk	Also, firmware for RTL8188CE was renamed due to possible name

1516bd79708dSJonathan T. Looney20161008:
1517bd79708dSJonathan T. Looney	Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
1518bd79708dSJonathan T. Looney	modules now requires that the kernel configuration contain the

1520bd79708dSJonathan T. Looney
15219ce3c6b0SEd Maste20161003:
15229ce3c6b0SEd Maste	The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.

1525bba95d2dSMarcel Moolenaar20160924:
1526bba95d2dSMarcel Moolenaar	Relocatable object files with the extension of .So have been renamed
1527bba95d2dSMarcel Moolenaar	to use an extension of .pico instead.  The purpose of this change is
1528bba95d2dSMarcel Moolenaar	to avoid a name clash with shared libraries on case-insensitive file
1529bba95d2dSMarcel Moolenaar	systems.  On those file systems, foo.So is the same file as foo.so.

15471c828193SNavdeep Parhar20160824:
15481c828193SNavdeep Parhar	r304787 changed some ioctl interfaces between the iSCSI userspace
15491c828193SNavdeep Parhar	programs and the kernel.  ctladm, ctld, iscsictl, and iscsid must be
15501c828193SNavdeep Parhar	rebuilt to work with new kernels.  __FreeBSD_version has been bumped
15511c828193SNavdeep Parhar	to 1200005.

15533e7e2333SGeorge V. Neville-Neil20160818:
155441029db1SRyan Stone	The UDP receive code has been updated to only treat incoming UDP
155541029db1SRyan Stone	packets that were addressed to an L2 broadcast address as L3
155641029db1SRyan Stone	broadcast packets.  It is not expected that this will affect any
155741029db1SRyan Stone	standards-conforming UDP application.  The new behaviour can be
155841029db1SRyan Stone	disabled by setting the sysctl net.inet.udp.require_l2_bcast to
155941029db1SRyan Stone	0.
156041029db1SRyan Stone
156141029db1SRyan Stone20160818:
15623e7e2333SGeorge V. Neville-Neil	Remove the openbsd_poll system call.
15633e7e2333SGeorge V. Neville-Neil	__FreeBSD_version has been bumped because of this.

1568ddc2f805SBrooks Davis20160622:
1569678243ffSBrooks Davis	The libc stub for the pipe(2) system call has been replaced with
1570f0db8553SBrooks Davis	a wrapper that calls the pipe2(2) system call and the pipe(2)
1571f0db8553SBrooks Davis	system call is now only implemented by the kernels that include
1572f0db8553SBrooks Davis	"options COMPAT_FREEBSD10" in their config file (this is the
1573f0db8553SBrooks Davis	default).  Users should ensure that this option is enabled in
1574f0db8553SBrooks Davis	their kernel or upgrade userspace to r302092 before upgrading their

1577583febf4SAlan Somers20160527:
1578857cde69SMaigurs Stalidzans	CAM now strips the leading spaces from each SCSI disk's serial number.
1579fb9b2ab1SBryan Drewery	This will affect users who create UFS filesystems on SCSI disks using
1580583febf4SAlan Somers	those disk's diskid device nodes.  For example, if /etc/fstab
1581583febf4SAlan Somers	previously contained a line like
1582583febf4SAlan Somers	"/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
1583583febf4SAlan Somers	change it to "/dev/diskid/DISK-ABCDEFG0123456".  Users of geom
1584ab5d7fb1SAlan Somers	transforms like gmirror may also be affected.  ZFS users should
1585583febf4SAlan Somers	generally be fine.
1586583febf4SAlan Somers
15871b82e02fSAlan Somers20160523:
15881b82e02fSAlan Somers	The bitstring(3) API has been updated with new functionality and
15891b82e02fSAlan Somers	improved performance.  But it is binary-incompatible with the old API.
15901b82e02fSAlan Somers	Objects built with the new headers may not be linked against objects

15992c0e9e2aSWarner Losh20160517:
16002c0e9e2aSWarner Losh	The armv6 port now defaults to hard float ABI. Limited support
16012c0e9e2aSWarner Losh	for running both hardfloat and soft float on the same system
16022c0e9e2aSWarner Losh	is available using the libraries installed with -DWITH_LIBSOFT.
16032c0e9e2aSWarner Losh	This has only been tested as an upgrade path for installworld

1632a1743365SWarner Losh	Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
1633a1743365SWarner Losh	with working NCQ TRIM. For Micron branded drives, see your sales rep for
1634a1743365SWarner Losh	updated firmware. Black listed drives will work correctly because these
1635a1743365SWarner Losh	drives work correctly so long as no NCQ TRIMs are sent to them. Given
1636a1743365SWarner Losh	this list is the same as found in Linux, it's believed there are no
1637a1743365SWarner Losh	other rogues in the market place. All other models from the above
1638a1743365SWarner Losh	vendors work.
1639a1743365SWarner Losh
1640a1743365SWarner Losh	To be safe, if you are at all concerned, you can quirk each of your
1641a1743365SWarner Losh	drives to prevent NCQ from being sent by setting:
1642a1743365SWarner Losh		kern.cam.ada.X.quirks="0x2"
1643a1743365SWarner Losh	in loader.conf. If the drive requires the 4k sector quirk, set the
1644a1743365SWarner Losh	quirks entry to 0x3.

1646497e8091SBryan Drewery20160330:
1647497e8091SBryan Drewery	The FAST_DEPEND build option has been removed and its functionality is
1648497e8091SBryan Drewery	now the one true way.  The old mkdep(1) style of 'make depend' has
1649497e8091SBryan Drewery	been removed.  See 20160311 for further details.
1650497e8091SBryan Drewery
1651da1b038aSJustin Hibbits20160317:
1652da1b038aSJustin Hibbits	Resource range types have grown from unsigned long to uintmax_t.  All
1653da1b038aSJustin Hibbits	drivers, and anything using libdevinfo, need to be recompiled.
1654da1b038aSJustin Hibbits
1655d783b170SBryan Drewery20160311:
1656d783b170SBryan Drewery	WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1657d783b170SBryan Drewery	builds.  It no longer runs mkdep(1) during 'make depend', and the
1658d783b170SBryan Drewery	'make depend' stage can safely be skipped now as it is auto ran
1659d783b170SBryan Drewery	when building 'make all' and will generate all SRCS and DPSRCS before
1660d783b170SBryan Drewery	building anything else.  Dependencies are gathered at compile time with
1661d783b170SBryan Drewery	-MF flags kept in separate .depend files per object file.  Users should
1662d783b170SBryan Drewery	run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1663d783b170SBryan Drewery	stale .depend files.

1665c834228bSDimitry Andric20160306:
1666c834228bSDimitry Andric	On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1667c834228bSDimitry Andric	kernel modules.  Therefore, if you load any kernel modules at boot time,
1668c834228bSDimitry Andric	please install the boot loaders after you install the kernel, but before
1669c834228bSDimitry Andric	rebooting, e.g.:
1670c834228bSDimitry Andric
1671c834228bSDimitry Andric	make buildworld
1672779f392bSJohn Baldwin	make buildkernel KERNCONF=YOUR_KERNEL_HERE
1673779f392bSJohn Baldwin	make installkernel KERNCONF=YOUR_KERNEL_HERE
1674c834228bSDimitry Andric	make -C sys/boot install
1675c834228bSDimitry Andric	<reboot in single user>
1676c834228bSDimitry Andric
1677c834228bSDimitry Andric	Then follow the usual steps, described in the General Notes section,
1678c834228bSDimitry Andric	below.
1679c834228bSDimitry Andric
1680e74e149fSDimitry Andric20160305:
1681e74e149fSDimitry Andric	Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0.  Please
1682e74e149fSDimitry Andric	see the 20141231 entry below for information about prerequisites and
1683e74e149fSDimitry Andric	upgrading, if you are not already using clang 3.5.0 or higher.

16858b66d3d3SJohn Baldwin20160301:
16868b66d3d3SJohn Baldwin	The AIO subsystem is now a standard part of the kernel.  The
16878b66d3d3SJohn Baldwin	VFS_AIO kernel option and aio.ko kernel module have been removed.
16888b66d3d3SJohn Baldwin	Due to stability concerns, asynchronous I/O requests are only
16898b66d3d3SJohn Baldwin	permitted on sockets and raw disks by default.  To enable
16908b66d3d3SJohn Baldwin	asynchronous I/O requests on all file types, set the
16918b66d3d3SJohn Baldwin	vfs.aio.enable_unsafe sysctl to a non-zero value.
16928b66d3d3SJohn Baldwin
1693de463b29SEd Maste20160226:
1694ca8b902aSEd Maste	The ELF object manipulation tool objcopy is now provided by the
1695ca8b902aSEd Maste	ELF Tool Chain project rather than by GNU binutils. It should be a
1696ca8b902aSEd Maste	drop-in replacement, with the addition of arm64 support. The
1697ca8b902aSEd Maste	(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1698ca8b902aSEd Maste	to obtain the GNU version if necessary.
1699ca8b902aSEd Maste
1700d4b9233aSAlan Somers20160129:
1701d4b9233aSAlan Somers	Building ZFS pools on top of zvols is prohibited by default.  That
1702d4b9233aSAlan Somers	feature has never worked safely; it's always been prone to deadlocks.
1703d4b9233aSAlan Somers	Using a zvol as the backing store for a VM guest's virtual disk will
1704d4b9233aSAlan Somers	still work, even if the guest is using ZFS.  Legacy behavior can be
1705d4b9233aSAlan Somers	restored by setting vfs.zfs.vol.recursive=1.
1706d4b9233aSAlan Somers
170760c59fadSDag-Erling Smørgrav20160119:
170860c59fadSDag-Erling Smørgrav	The NONE and HPN patches has been removed from OpenSSH.  They are
170960c59fadSDag-Erling Smørgrav	still available in the security/openssh-portable port.
171060c59fadSDag-Erling Smørgrav
17113bf7d9a6SMarcelo Araujo20160113:
17123bf7d9a6SMarcelo Araujo	With the addition of ypldap(8), a new _ypldap user is now required
17133bf7d9a6SMarcelo Araujo	during installworld. "mergemaster -p" can be used to add the user
17143bf7d9a6SMarcelo Araujo	prior to installworld, as documented in the handbook.
17153bf7d9a6SMarcelo Araujo
17164d6ab32fSBaptiste Daroussin20151216:
17174d6ab32fSBaptiste Daroussin	The tftp loader (pxeboot) now uses the option root-path directive. As a
17184d6ab32fSBaptiste Daroussin	consequence it no longer looks for a pxeboot.4th file on the tftp
17194d6ab32fSBaptiste Daroussin	server. Instead it uses the regular /boot infrastructure as with the
17204d6ab32fSBaptiste Daroussin	other loaders.
17214d6ab32fSBaptiste Daroussin
1722ca7e5285SWarner Losh20151211:
1723ca7e5285SWarner Losh	The code to start recording plug and play data into the modules has
1724ca7e5285SWarner Losh	been committed. While the old tools will properly build a new kernel,
1725ca7e5285SWarner Losh	a number of warnings about "unknown metadata record 4" will be produced
1726ca7e5285SWarner Losh	for an older kldxref. To avoid such warnings, make sure to rebuild
1727ca7e5285SWarner Losh	the kernel toolchain (or world). Make sure that you have r292078 or
1728ca7e5285SWarner Losh	later when trying to build 292077 or later before rebuilding.
1729ca7e5285SWarner Losh
1730015dfda6SEd Maste20151207:
1731015dfda6SEd Maste	Debug data files are now built by default with 'make buildworld' and
1732015dfda6SEd Maste	installed with 'make installworld'. This facilitates debugging but
1733015dfda6SEd Maste	requires more disk space both during the build and for the installed
1734015dfda6SEd Maste	world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1735015dfda6SEd Maste	in src.conf(5).
1736015dfda6SEd Maste
173733ba1088SRick Macklem20151130:
173833ba1088SRick Macklem	r291527 changed the internal interface between the nfsd.ko and
173933ba1088SRick Macklem	nfscommon.ko modules. As such, they must both be upgraded to-gether.
174033ba1088SRick Macklem	__FreeBSD_version has been bumped because of this.
174133ba1088SRick Macklem
1742af1d74f0SBaptiste Daroussin20151108:
1743af1d74f0SBaptiste Daroussin	Add support for unicode collation strings leads to a change of
1744af1d74f0SBaptiste Daroussin	order of files listed by ls(1) for example. To get back to the old
1745af1d74f0SBaptiste Daroussin	behaviour, set LC_COLLATE environment variable to "C".
1746af1d74f0SBaptiste Daroussin
17470492a14fSBaptiste Daroussin	Databases administrators will need to reindex their databases given
17480492a14fSBaptiste Daroussin	collation results will be different.
17490492a14fSBaptiste Daroussin
175010b5202eSBaptiste Daroussin	Due to a bug in install(1) it is recommended to remove the ancient
17511300d6f1SBaptiste Daroussin	locales before running make installworld.
175201bedb0cSBaptiste Daroussin
17531300d6f1SBaptiste Daroussin	rm -rf /usr/share/locale/*
175401bedb0cSBaptiste Daroussin
17557bded2dbSJung-uk Kim20151030:
17567bded2dbSJung-uk Kim	The OpenSSL has been upgraded to 1.0.2d.  Any binaries requiring
17577bded2dbSJung-uk Kim	libcrypto.so.7 or libssl.so.7 must be recompiled.
17587bded2dbSJung-uk Kim
1759ebda5173SAlexander Motin20151020:
1760ebda5173SAlexander Motin	Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1761ebda5173SAlexander Motin	Kernel modules isp_2400_multi and isp_2500_multi were removed and
1762ebda5173SAlexander Motin	should be replaced with isp_2400 and isp_2500 modules respectively.
1763ebda5173SAlexander Motin
176456585ab5SBryan Drewery20151017:
176556585ab5SBryan Drewery	The build previously allowed using 'make -n' to not recurse into
176656585ab5SBryan Drewery	sub-directories while showing what commands would be executed, and
176756585ab5SBryan Drewery	'make -n -n' to recursively show commands.  Now 'make -n' will recurse
176856585ab5SBryan Drewery	and 'make -N' will not.
176956585ab5SBryan Drewery
1770ff446b05SPeter Wemm20151012:
1771ff446b05SPeter Wemm	If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1772ff446b05SPeter Wemm	and etcupdate will now use this file. A custom sendmail.cf is now
1773ff446b05SPeter Wemm	updated via this mechanism rather than via installworld.  If you had
1774ff446b05SPeter Wemm	excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1775ff446b05SPeter Wemm	want to remove the exclusion or change it to "always install".
1776ff446b05SPeter Wemm	/etc/mail/sendmail.cf is now managed the same way regardless of
1777ff446b05SPeter Wemm	whether SENDMAIL_MC/SENDMAIL_CF is used.  If you are not using
1778ff446b05SPeter Wemm	SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1779ff446b05SPeter Wemm
17804a3760baSAlexander Motin20151011:
17814a3760baSAlexander Motin	Compatibility shims for legacy ATA device names have been removed.
17824a3760baSAlexander Motin	It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
17834a3760baSAlexander Motin	and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
17844a3760baSAlexander Motin	environment variables, /dev/ad* and /dev/ar* symbolic links.

1786d31de548SDimitry Andric20151006:
17874f01407bSDimitry Andric	Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
17884f01407bSDimitry Andric	Please see the 20141231 entry below for information about prerequisites
17894f01407bSDimitry Andric	and upgrading, if you are not already using clang 3.5.0 or higher.
1790ebeff3f9SDimitry Andric
17915882166bSEd Maste20150924:
179205117b57SEd Maste	Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
179305117b57SEd Maste	and renamed from .symbols to .debug. This reduces the size requirements
179405117b57SEd Maste	on the boot partition or file system and provides consistency with
179505117b57SEd Maste	userland debug files.
179605117b57SEd Maste
179705117b57SEd Maste	When using the supported kernel installation method the
179805117b57SEd Maste	/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
179905117b57SEd Maste	as is done with /boot/kernel.
180005117b57SEd Maste
180105117b57SEd Maste	Developers wishing to maintain the historical behavior of installing
180205117b57SEd Maste	debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
180305117b57SEd Maste
180464b3b4d6SKristof Provost20150827:
18058ed69220SGleb Smirnoff	The wireless drivers had undergone changes that remove the 'parent
18068ed69220SGleb Smirnoff	interface' from the ifconfig -l output. The rc.d network scripts
18078ed69220SGleb Smirnoff	used to check presence of a parent interface in the list, so old
18088ed69220SGleb Smirnoff	scripts would fail to start wireless networking. Thus, etcupdate(3)
18098ed69220SGleb Smirnoff	or mergemaster(8) run is required after kernel update, to update your
18108ed69220SGleb Smirnoff	rc.d scripts in /etc.
18118ed69220SGleb Smirnoff
18128ed69220SGleb Smirnoff20150827:
181364b3b4d6SKristof Provost	pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
181464b3b4d6SKristof Provost	These configurations are now automatically interpreted as
181564b3b4d6SKristof Provost	'scrub fragment reassemble'.
181664b3b4d6SKristof Provost
1817646041a8SMark Murray20150817:
1818646041a8SMark Murray	Kernel-loadable modules for the random(4) device are back. To use
1819646041a8SMark Murray	them, the kernel must have
1820646041a8SMark Murray
1821646041a8SMark Murray	device	random
1822646041a8SMark Murray	options	RANDOM_LOADABLE
1823646041a8SMark Murray
1824646041a8SMark Murray	kldload(8) can then be used to load random_fortuna.ko
1825646041a8SMark Murray	or random_yarrow.ko. Please note that due to the indirect
1826646041a8SMark Murray	function calls that the loadable modules need to provide,
1827646041a8SMark Murray	the build-in variants will be slightly more efficient.
1828646041a8SMark Murray
1829646041a8SMark Murray	The random(4) kernel option RANDOM_DUMMY has been retired due to
1830646041a8SMark Murray	unpopularity. It was not all that useful anyway.
1831646041a8SMark Murray
18321bc28ffcSEd Maste20150813:
18331bc28ffcSEd Maste	The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
18341bc28ffcSEd Maste	Control over building the ELF Tool Chain tools is now provided by
18351bc28ffcSEd Maste	the WITHOUT_TOOLCHAIN knob.
18361bc28ffcSEd Maste
1837e7dbaf58SIan Lepore20150810:
1838e7dbaf58SIan Lepore	The polarity of Pulse Per Second (PPS) capture events with the
1839e7dbaf58SIan Lepore	uart(4) driver has been corrected.  Prior to this change the PPS
1840e7dbaf58SIan Lepore	"assert" event corresponded to the trailing edge of a positive PPS
1841e7dbaf58SIan Lepore	pulse and the "clear" event was the leading edge of the next pulse.
1842e7dbaf58SIan Lepore
1843e7dbaf58SIan Lepore	As the width of a PPS pulse in a typical GPS receiver is on the
1844e7dbaf58SIan Lepore	order of 1 millisecond, most users will not notice any significant
1845e7dbaf58SIan Lepore	difference with this change.
1846e7dbaf58SIan Lepore
1847e7dbaf58SIan Lepore	Anyone who has compensated for the historical polarity reversal by
1848e7dbaf58SIan Lepore	configuring a negative offset equal to the pulse width will need to
1849e7dbaf58SIan Lepore	remove that workaround.
1850e7dbaf58SIan Lepore
185134c7eb57SKoop Mast20150809:
185234c7eb57SKoop Mast	The default group assigned to /dev/dri entries has been changed
185334c7eb57SKoop Mast	from 'wheel' to 'video' with the id of '44'. If you want to have

18599322ac3fSAllan Jude20150806:
18609322ac3fSAllan Jude	The menu.rc and loader.rc files will now be replaced during
18619322ac3fSAllan Jude	upgrades. Please migrate local changes to menu.rc.local and

18639322ac3fSAllan Jude
1864f97aa232SEd Maste20150805:
1865f97aa232SEd Maste	GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1866f97aa232SEd Maste	strings and strip have been removed. The src.conf(5) knob
1867f97aa232SEd Maste	WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
1868f97aa232SEd Maste
18691635369eSSteven Hartland20150728:
187068d5f492SSteven Hartland	As ZFS requires more kernel stack pages than is the default on some
18711635369eSSteven Hartland	architectures e.g. i386, it now warns if KSTACK_PAGES is less than
18721635369eSSteven Hartland	ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
18731635369eSSteven Hartland
18741635369eSSteven Hartland	Please consider using 'options KSTACK_PAGES=X' where X is greater
18751635369eSSteven Hartland	than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
18761635369eSSteven Hartland
1877ab1f4a42SGregory Neil Shapiro20150706:
1878ab1f4a42SGregory Neil Shapiro	sendmail has been updated to 8.15.2.  Starting with FreeBSD 11.0
1879ab1f4a42SGregory Neil Shapiro	and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1880ab1f4a42SGregory Neil Shapiro	default, i.e., they will not contain "::".  For example, instead
1881ab1f4a42SGregory Neil Shapiro	of ::1, it will be 0:0:0:0:0:0:0:1.  This permits a zero subnet
1882ab1f4a42SGregory Neil Shapiro	to have a more specific match, such as different map entries for
1883ab1f4a42SGregory Neil Shapiro	IPv6:0:0 vs IPv6:0.  This change requires that configuration
1884ab1f4a42SGregory Neil Shapiro	data (including maps, files, classes, custom ruleset, etc.) must
1885ab1f4a42SGregory Neil Shapiro	use the same format, so make certain such configuration data is
1886ab1f4a42SGregory Neil Shapiro	upgrading.  As a very simple check search for patterns like
1887ab1f4a42SGregory Neil Shapiro	'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'.  To return to the old
1888ab1f4a42SGregory Neil Shapiro	behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1889ab1f4a42SGregory Neil Shapiro	the cf option UseCompressedIPv6Addresses.
1890ab1f4a42SGregory Neil Shapiro
1891d1b06863SMark Murray20150630:
1892d1b06863SMark Murray	The default kernel entropy-processing algorithm is now
1893d1b06863SMark Murray	Fortuna, replacing Yarrow.
18946f78e390SSimon J. Gerraty
1895d1b06863SMark Murray	Assuming you have 'device random' in your kernel config

1902d1b06863SMark Murray	If you have neither, you get Fortuna.  For most people,
1903d1b06863SMark Murray	read no further, Fortuna will give a /dev/random that works
1904d1b06863SMark Murray	like it always used to, and the difference will be irrelevant.

1906d1b06863SMark Murray	If you remove 'device random', you get *NO* kernel-processed
190702dcb6e0SEitan Adler	entropy at all. This may be acceptable to folks building
1908d1b06863SMark Murray	embedded systems, but has complications. Carry on reading,
1909d1b06863SMark Murray	and it is assumed you know what you need.
1910d1b06863SMark Murray
1911d1b06863SMark Murray	*PLEASE* read random(4) and random(9) if you are in the
191202dcb6e0SEitan Adler	habit of tweaking kernel configs, and/or if you are a member
1913d1b06863SMark Murray	of the embedded community, wanting specific and not-usual
1914d1b06863SMark Murray	behaviour from your security subsystems.
1915d1b06863SMark Murray
1916d1b06863SMark Murray	NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1917d1b06863SMark Murray	random', you will NOT have a functioning /dev/random, and
1918d1b06863SMark Murray	many cryptographic features will not work, including SSH.
1919d1b06863SMark Murray	You may also find strange behaviour from the random(3) set
1920d1b06863SMark Murray	of library functions, in particular sranddev(3), srandomdev(3)
1921d1b06863SMark Murray	and arc4random(3). The reason for this is that the KERN_ARND
1922d1b06863SMark Murray	sysctl only returns entropy if it thinks it has some to
1923d1b06863SMark Murray	share, and with RANDOM_DUMMY or no 'device random' this
1924d1b06863SMark Murray	will never happen.

2075143c11b4SDimitry Andric	Clang, llvm and lldb have been upgraded to 3.5.0 release.
2076143c11b4SDimitry Andric
20770ac2c3d1SDimitry Andric	As of this release, a prerequisite for building clang, llvm and lldb is
20780ac2c3d1SDimitry Andric	a C++11 capable compiler and C++11 standard library.  This means that to
2079143c11b4SDimitry Andric	be able to successfully build the cross-tools stage of buildworld, with
2080143c11b4SDimitry Andric	clang as the bootstrap compiler, your system compiler or cross compiler
2081143c11b4SDimitry Andric	should either be clang 3.3 or later, or gcc 4.8 or later, and your
2082143c11b4SDimitry Andric	system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
2083143c11b4SDimitry Andric	later.
2084143c11b4SDimitry Andric
20850ac2c3d1SDimitry Andric	On any standard FreeBSD 10.x or 11.x installation, where clang and
20860ac2c3d1SDimitry Andric	libc++ are on by default (that is, on x86 or arm), this should work out
20870ac2c3d1SDimitry Andric	of the box.
2088143c11b4SDimitry Andric
2089143c11b4SDimitry Andric	On 9.x installations where clang is enabled by default, e.g. on x86 and
2090143c11b4SDimitry Andric	powerpc, libc++ will not be enabled by default, so libc++ should be
2091143c11b4SDimitry Andric	built (with clang) and installed first.  If both clang and libc++ are
2092143c11b4SDimitry Andric	missing, build clang first, then use it to build libc++.
2093143c11b4SDimitry Andric
2094143c11b4SDimitry Andric	On 8.x and earlier installations, upgrade to 9.x first, and then follow
2095143c11b4SDimitry Andric	the instructions for 9.x above.
2096143c11b4SDimitry Andric
20970ac2c3d1SDimitry Andric	Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
20980ac2c3d1SDimitry Andric	default, and do not build clang.
20990ac2c3d1SDimitry Andric
21000ac2c3d1SDimitry Andric	Many embedded systems are resource constrained, and will not be able to
21010ac2c3d1SDimitry Andric	build clang in a reasonable time, or in some cases at all.  In those
21020ac2c3d1SDimitry Andric	cases, cross building bootable systems on amd64 is a workaround.
21030ac2c3d1SDimitry Andric
2104143c11b4SDimitry Andric	This new version of clang introduces a number of new warnings, of which
2105143c11b4SDimitry Andric	the following are most likely to appear:
2106143c11b4SDimitry Andric
2107143c11b4SDimitry Andric	-Wabsolute-value
2108143c11b4SDimitry Andric
2109143c11b4SDimitry Andric	This warns in two cases, for both C and C++:
2110143c11b4SDimitry Andric	* When the code is trying to take the absolute value of an unsigned
2111143c11b4SDimitry Andric	  quantity, which is effectively a no-op, and almost never what was
2112143c11b4SDimitry Andric	  intended.  The code should be fixed, if at all possible.  If you are
2113143c11b4SDimitry Andric	  sure that the unsigned quantity can be safely cast to signed, without
2114143c11b4SDimitry Andric	  loss of information or undefined behavior, you can add an explicit
2115143c11b4SDimitry Andric	  cast, or disable the warning.
2116143c11b4SDimitry Andric
2117143c11b4SDimitry Andric	* When the code is trying to take an absolute value, but the called
2118143c11b4SDimitry Andric	  abs() variant is for the wrong type, which can lead to truncation.
2119143c11b4SDimitry Andric	  If you want to disable the warning instead of fixing the code, please
2120143c11b4SDimitry Andric	  make sure that truncation will not occur, or it might lead to unwanted
2121143c11b4SDimitry Andric	  side-effects.
2122143c11b4SDimitry Andric
2123143c11b4SDimitry Andric	-Wtautological-undefined-compare and
2124143c11b4SDimitry Andric	-Wundefined-bool-conversion
2125143c11b4SDimitry Andric
2126143c11b4SDimitry Andric	These warn when C++ code is trying to compare 'this' against NULL, while
2127143c11b4SDimitry Andric	'this' should never be NULL in well-defined C++ code.  However, there is
2128143c11b4SDimitry Andric	some legacy (pre C++11) code out there, which actively abuses this
2129143c11b4SDimitry Andric	feature, which was less strictly defined in previous C++ versions.
2130143c11b4SDimitry Andric
2131143c11b4SDimitry Andric	Squid and openjdk do this, for example.  The warning can be turned off
2132143c11b4SDimitry Andric	for C++98 and earlier, but compiling the code in C++11 mode might result
2133143c11b4SDimitry Andric	in unexpected behavior; for example, the parts of the program that are
2134143c11b4SDimitry Andric	unreachable could be optimized away.

2250727a7ce8SJulio Merino20140606:
2251727a7ce8SJulio Merino	The libatf-c and libatf-c++ major versions were downgraded to 0 and
2252727a7ce8SJulio Merino	1 respectively to match the upstream numbers.  They were out of
2253727a7ce8SJulio Merino	sync because, when they were originally added to FreeBSD, the
2254727a7ce8SJulio Merino	upstream versions were not respected.  These libraries are private
2255727a7ce8SJulio Merino	and not yet built by default, so renumbering them should be a
2256727a7ce8SJulio Merino	non-issue.  However, unclean source trees will yield broken test
2257727a7ce8SJulio Merino	programs once the operator executes "make delete-old-libs" after a
2258727a7ce8SJulio Merino	"make installworld".
2259727a7ce8SJulio Merino
22608c7ec47aSJulio Merino	Additionally, the atf-sh binary was made private by moving it into
22618c7ec47aSJulio Merino	/usr/libexec/.  Already-built shell test programs will keep the
22628c7ec47aSJulio Merino	path to the old binary so they will break after "make delete-old"
22638c7ec47aSJulio Merino	is run.
22648c7ec47aSJulio Merino
2265727a7ce8SJulio Merino	If you are using WITH_TESTS=yes (not the default), wipe the object
2266727a7ce8SJulio Merino	tree and rebuild from scratch to prevent spurious test failures.
22678c7ec47aSJulio Merino	This is only needed once: the misnumbered libraries and misplaced
22688c7ec47aSJulio Merino	binaries have been added to OptionalObsoleteFiles.inc so they will
22698c7ec47aSJulio Merino	be removed during a clean upgrade.

2274fa114234SWarner Losh20140508:
2275fa114234SWarner Losh	We bogusly installed src.opts.mk in /usr/share/mk. This file should
2276fa114234SWarner Losh	be removed to avoid issues in the future (and has been added to
2277fa114234SWarner Losh	ObsoleteFiles.inc).
2278fa114234SWarner Losh
2279a46954e2SWarner Losh20140505:
2280a46954e2SWarner Losh	/etc/src.conf now affects only builds of the FreeBSD src tree. In the
2281a46954e2SWarner Losh	past, it affected all builds that used the bsd.*.mk files. The old
2282a46954e2SWarner Losh	behavior was a bug, but people may have relied upon it. To get this
2283a46954e2SWarner Losh	behavior back, you can .include /etc/src.conf from /etc/make.conf
2284a46954e2SWarner Losh	(which is still global and isn't changed). This also changes the
2285a46954e2SWarner Losh	behavior of incremental builds inside the tree of individual
228659a24370SWarner Losh	directories. Set MAKESYSPATH to ".../share/mk" to do that.
2287a46954e2SWarner Losh	Although this has survived make universe and some upgrade scenarios,
228855b76981SWarner Losh	other upgrade scenarios may have broken. At least one form of
228955b76981SWarner Losh	temporary breakage was fixed with MAKESYSPATH settings for buildworld
229059a24370SWarner Losh	as well... In cases where MAKESYSPATH isn't working with this
229159a24370SWarner Losh	setting, you'll need to set it to the full path to your tree.
2292a46954e2SWarner Losh
2293bd871f14SWarner Losh	One side effect of all this cleaning up is that bsd.compiler.mk
2294bd871f14SWarner Losh	is no longer implicitly included by bsd.own.mk. If you wish to
2295bd871f14SWarner Losh	use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2296bd871f14SWarner Losh	as well.

2302e9aba509SEnji Cooper20140424:
2303e9aba509SEnji Cooper	The knob WITHOUT_VI was added to the base system, which controls
2304e9aba509SEnji Cooper	building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2305e9aba509SEnji Cooper	in order to reorder files share/termcap and didn't build ex(1) as a
2306e9aba509SEnji Cooper	build tool, so building/installing with WITH_VI is highly advised for
2307e9aba509SEnji Cooper	build hosts for older releases.
2308e9aba509SEnji Cooper
2309e9aba509SEnji Cooper	This issue has been fixed in stable/9 and stable/10 in r277022 and

23174c710b67SMarcel Moolenaar20140405:
23184c710b67SMarcel Moolenaar	The uart(4) driver has been changed with respect to its handling
23194c710b67SMarcel Moolenaar	of the low-level console. Previously the uart(4) driver prevented
23204c710b67SMarcel Moolenaar	any process from changing the baudrate or the CLOCAL and HUPCL
23214c710b67SMarcel Moolenaar	control flags. By removing the restrictions, operators can make
23224c710b67SMarcel Moolenaar	changes to the serial console port without having to reboot.
23234c710b67SMarcel Moolenaar	However, when getty(8) is started on the serial device that is
23244c710b67SMarcel Moolenaar	associated with the low-level console, a misconfigured terminal
23254c710b67SMarcel Moolenaar	line in /etc/ttys will now have a real impact.
23264c710b67SMarcel Moolenaar	Before upgrading the kernel, make sure that /etc/ttys has the
23274c710b67SMarcel Moolenaar	serial console device configured as 3wire without baudrate to
2328086036aaSMarcel Moolenaar	preserve the previous behaviour. E.g:
23294c710b67SMarcel Moolenaar	    ttyu0  "/usr/libexec/getty 3wire"  vt100  on  secure

2337a9fd2218SWarner Losh	Switched back to the GPL dtc compiler due to updates in the upstream
2338a9fd2218SWarner Losh	dts files not being supported by the BSDL dtc compiler. You will need
2339a9fd2218SWarner Losh	to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2340a9fd2218SWarner Losh	may result while building dtb files during a kernel build if you fail
2341a9fd2218SWarner Losh	to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.

23519f23d19aSDimitry Andric	An ABI incompatibility crept into the libc++ 3.4 import in r261283.
23529f23d19aSDimitry Andric	This could cause certain C++ applications using shared libraries built
23539f23d19aSDimitry Andric	against the previous version of libc++ to crash.  The incompatibility
23549f23d19aSDimitry Andric	has now been fixed, but any C++ applications or shared libraries built
23559f23d19aSDimitry Andric	between r261283 and r261801 should be recompiled.

2374d7efee23SJulio Merino20140110:
2375d7efee23SJulio Merino	If a Makefile in a tests/ directory was auto-generating a Kyuafile
2376d7efee23SJulio Merino	instead of providing an explicit one, this would prevent such
2377d7efee23SJulio Merino	Makefile from providing its own Kyuafile in the future during
2378d7efee23SJulio Merino	NO_CLEAN builds.  This has been fixed in the Makefiles but manual

23832773bfa9SBenjamin Kaduk	The behavior of gss_pseudo_random() for the krb5 mechanism
23842773bfa9SBenjamin Kaduk	has changed, for applications requesting a longer random string
23852773bfa9SBenjamin Kaduk	than produced by the underlying enctype's pseudo-random() function.
23862773bfa9SBenjamin Kaduk	In particular, the random string produced from a session key of
23872773bfa9SBenjamin Kaduk	enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
23882773bfa9SBenjamin Kaduk	be different at the 17th octet and later, after this change.

2422a24eff53SWarner Losh	-------------
24235780f3baSWarner Losh	Sometimes, obscure build problems are the result of environment
24245780f3baSWarner Losh	poisoning.  This can happen because the make utility reads its
2425456b5dd8SWarner Losh	environment when searching for values for global variables.  To run
2426456b5dd8SWarner Losh	your build attempts in an "environmental clean room", prefix all make
2427456b5dd8SWarner Losh	commands with 'env -i '.  See the env(1) manual page for more details.
242816ae8351SEd Maste	Occasionally a build failure will occur with "make -j" due to a race
242916ae8351SEd Maste	condition.  If this happens try building again without -j, and please
243016ae8351SEd Maste	report a bug if it happens consistently.

24345ad05815SWarner Losh	do an upgrade to the new branch. This is the best-tested upgrade path,
24355ad05815SWarner Losh	and has the highest probability of being successful.  Please try this
24365ad05815SWarner Losh	approach if you encounter problems with a major version upgrade.  Since
243744c1484aSJens Schweikhardt	the stable 4.x branch point, one has generally been able to upgrade from
24385ad05815SWarner Losh	anywhere in the most recent stable branch to head / current (or even the
24395ad05815SWarner Losh	last couple of stable branches). See the top of this file when there's
24405ad05815SWarner Losh	an exception.

244356cd269eSEd Maste	or install from a FreeBSD version below the earliest supported version.
244456cd269eSEd Maste	When updating from an older version the update should be performed one

24486eeab389SWarner Losh	When upgrading a live system, having a root shell around before
2449da0e842aSWarner Losh	installing anything can help undo problems. Not having a root shell
2450da0e842aSWarner Losh	around can lead to problems if pam has changed too much from your
2451da0e842aSWarner Losh	starting point to allow continued authentication after the upgrade.

24608fc25799SMartin Matuska	ZFS notes
24618fc25799SMartin Matuska	---------
24628fc25799SMartin Matuska	When upgrading the boot ZFS pool to a new version, always follow
24638fc25799SMartin Matuska	these two steps:
24648fc25799SMartin Matuska
24658fc25799SMartin Matuska	1.) recompile and reinstall the ZFS boot loader and boot block
24668fc25799SMartin Matuska	(this is part of "make buildworld" and "make installworld")
24678fc25799SMartin Matuska
24688fc25799SMartin Matuska	2.) update the ZFS boot block on your boot drive
24698fc25799SMartin Matuska
2470d8e59012SColin Percival	The following example updates the ZFS boot block on the
2471d8e59012SColin Percival	freebsd-boot partition of a GPT partitioned drive ada0:
2472d8e59012SColin Percival	"gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2473d8e59012SColin Percival	The value $N will typically be 1 (if booting from BIOS) or 2 (if
2474d8e59012SColin Percival	booting from EFI).
24758fc25799SMartin Matuska
24768fc25799SMartin Matuska	Non-boot pools do not need these updates.

2480ba01eb20SWarner Losh	If you are updating from a prior version of FreeBSD (even one just
24811cf0ef11SDavid E. O'Brien	a few days old), you should follow this procedure.  It is the most

24902e937dd6SAlexander Leidinger	If you just want to boot a kernel once (because you are not sure
24912e937dd6SAlexander Leidinger	if it works, or if you want to boot a known bad kernel to provide

2550ba26da8eSWarner Losh
2551fdb9f54dSWarner Losh	Make sure that you've read the UPDATING file to understand the
2552fdb9f54dSWarner Losh	tweaks to various things you need.  At this point in the life
2553fdb9f54dSWarner Losh	cycle of current, things change often and you are on your own
2554fdb9f54dSWarner Losh	to cope.  The defaults can also change, so please read ALL of
2555fdb9f54dSWarner Losh	the UPDATING entries.
2556ba26da8eSWarner Losh
25571dece4a9SWarner Losh	Also, if you are tracking -current, you must be subscribed to
25581dece4a9SWarner Losh	freebsd-current@freebsd.org.  Make sure that before you update
25591dece4a9SWarner Losh	your sources that you have read and understood all the recent
25601dece4a9SWarner Losh	messages there.  If in doubt, please track -stable which has
25611dece4a9SWarner Losh	much fewer pitfalls.
25621dece4a9SWarner Losh
2563d2799054SWarner Losh	[1] If you have third party modules, such as vmware, you should disable
2564d2799054SWarner Losh	them at this point so they don't crash your system on
2565d2799054SWarner Losh	reboot. Alternatively, you should rebuild all the modules you have in
2566d2799054SWarner Losh	your system and install them as well.  If you are running -current, you
2567d2799054SWarner Losh	should seriously consider placing all sources to all the modules for
2568d2799054SWarner Losh	your system (or symlinks to them) in /usr/local/sys/modules so this
2569d2799054SWarner Losh	happens automatically. If all your modules come from ports, then adding
2570d2799054SWarner Losh	the port origin directories to PORTS_MODULES instead is also automatic
2571d2799054SWarner Losh	and effective, eg:
2572d2799054SWarner Losh	     PORTS_MODULES+=x11/nvidia-driver
2573134d2e86SWarner Losh
2574ee6e1fc3SWarner Losh	[3] From the bootblocks, boot -s, and then do
2575ee6e1fc3SWarner Losh		fsck -p
2576ee6e1fc3SWarner Losh		mount -u /
2577ee6e1fc3SWarner Losh		mount -a
25788ed2d94aSWarner Losh		sh /etc/rc.d/zfs start	# mount zfs filesystem, if needed
25798ed2d94aSWarner Losh		cd src			# full path to source
258047d0d01fSWarner Losh		adjkerntz -i		# if CMOS is wall time
2581d2799054SWarner Losh	Also, when doing a major release upgrade, it is required that you boot
2582d2799054SWarner Losh	into single user mode to do the installworld.
2583ee6e1fc3SWarner Losh
2584a6cd4f9dSWarner Losh	[4] Note: This step is non-optional.  Failure to do this step
2585a6cd4f9dSWarner Losh	can result in a significant reduction in the functionality of the
2586a6cd4f9dSWarner Losh	system.  Attempting to do it by hand is not recommended and those
2587a6cd4f9dSWarner Losh	that pursue this avenue should read this file carefully, as well
2588a6cd4f9dSWarner Losh	as the archives of freebsd-current and freebsd-hackers mailing lists
2589e641c29aSDries Michiels	for potential gotchas.  See etcupdate(8) for more information.
2590a6cd4f9dSWarner Losh
259144c1484aSJens Schweikhardt	[5] Usually this step is a no-op.  However, from time to time
2592835284beSWarner Losh	you may need to do this if you get unknown user in the following
2593e641c29aSDries Michiels	step.
2594835284beSWarner Losh
259594877c06SAlexander Leidinger	[6] This only deletes old files and directories. Old libraries
259694877c06SAlexander Leidinger	can be deleted by "make delete-old-libs", but you have to make
259794877c06SAlexander Leidinger	sure that no program is using those libraries anymore.
259894877c06SAlexander Leidinger
2599ed651a74SWarner Losh	[8] The new kernel must be able to run existing binaries used by an
2600ed651a74SWarner Losh	installworld.  When upgrading across major versions, the new kernel's
2601ed651a74SWarner Losh	configuration must include the correct COMPAT_FREEBSD<n> option for
2602ed651a74SWarner Losh	existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries).  Failure
2603ed651a74SWarner Losh	to do so may leave you with a system that is hard to boot to recover. A
2604ed651a74SWarner Losh	GENERIC kernel will include suitable compatibility options to run
2605ed651a74SWarner Losh	binaries from older branches.  Note that the ability to run binaries
2606ed651a74SWarner Losh	from unsupported branches is not guaranteed.
2607c74fe6afSWarner Losh
2608e5dc5f61SWarner Losh	Make sure that you merge any new devices from GENERIC since the
26098ed2d94aSWarner Losh	last time you updated your kernel config file. Options also
26108ed2d94aSWarner Losh	change over time, so you may need to adjust your custom kernels
26118ed2d94aSWarner Losh	for these as well.
2612e5dc5f61SWarner Losh
2613e5f5a852SEitan Adler	[9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2614e5dc5f61SWarner Losh	"?=" instead of the "=" assignment operator, so that buildworld can
2615e5dc5f61SWarner Losh	override the CPUTYPE if it needs to.
2616e5dc5f61SWarner Losh
2617e5dc5f61SWarner Losh	MAKEOBJDIRPREFIX must be defined in an environment variable, and
2618e5dc5f61SWarner Losh	not on the command line, or in /etc/make.conf.  buildworld will
2619e5dc5f61SWarner Losh	warn if it is improperly defined.
