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*b8cacb38SWarner Losh20211209:
31*b8cacb38SWarner Losh	Remove mips as a recognized target. This starts the decommissioning of
32*b8cacb38SWarner Losh	mips support in FreeBSD. mips related items will be removed wholesale in
33*b8cacb38SWarner Losh	the coming days and weeks.

35b8d60729SRandall Stewart20211110:
36d6953863SRandall Stewart	Commit b8d60729deef changed the TCP congestion control framework so
37b8d60729SRandall Stewart	that any of the included congestion control modules could be
38b8d60729SRandall Stewart	the single module built into the kernel. Previously newreno
39b8d60729SRandall Stewart	was automatically built in through direct reference. Has of
40b8d60729SRandall Stewart	this commit you are required to declare at least one congestion
41b8d60729SRandall Stewart	control module (e.g. 'options CC_NEWRENO') and to also delcare a
42b8d60729SRandall Stewart	default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\").
43b8d60729SRandall Stewart	The GENERIC configuation includes CC_NEWRENO and defines newreno
44b8d60729SRandall Stewart	as the default. If no congestion control option is built into the
45b8d60729SRandall Stewart	kernel and you are including networking, the kernel compile will
46b8d60729SRandall Stewart	fail. Also if no default is declared the kernel compile will fail.
47b8d60729SRandall Stewart
4867301655SWarner Losh20211118:
4967301655SWarner Losh	Mips has been removed from universe builds. It will be removed from the
5067301655SWarner Losh	tree shortly.
5167301655SWarner Losh
5225b0021dSRick Macklem20211106:
5325b0021dSRick Macklem	Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE.
5425b0021dSRick Macklem	The NFS modules must be rebuilt from sources and any out
5525b0021dSRick Macklem	of tree file systems that implement their own VOP_ALLOCATE
5625b0021dSRick Macklem	may need to be modified.
5725b0021dSRick Macklem
586aae3517SGleb Smirnoff20211022:
596aae3517SGleb Smirnoff	The synchronous PPP kernel driver sppp(4) has been removed.
606aae3517SGleb Smirnoff	The cp(4) and ce(4) drivers are now always compiled with netgraph(4)
616aae3517SGleb Smirnoff	support, formerly enabled by NETGRAPH_CRONYX option.
626aae3517SGleb Smirnoff
63d410b585SBaptiste Daroussin20211020:
646ae38ab4SBaptiste Daroussin	sh(1) is now the default shell for the root user.  To force root to use
65d410b585SBaptiste Daroussin	the csh shell, please run the following command as root:
66d410b585SBaptiste Daroussin
676ae38ab4SBaptiste Daroussin	# chsh -s csh
68d410b585SBaptiste Daroussin
6916f1ee11SBaptiste Daroussin20211004:
7016f1ee11SBaptiste Daroussin	Ncurses distribution has been split between libtinfow and libncurses
7116f1ee11SBaptiste Daroussin	with libncurses.so becoming a linker (ld) script to seamlessly link
7216f1ee11SBaptiste Daroussin	to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect
7316f1ee11SBaptiste Daroussin	this change.
7416f1ee11SBaptiste Daroussin
759cce0ef9SKristof Provost20210923:
769cce0ef9SKristof Provost	As of commit 8160a0f62be6, the dummynet module no longer depends on the
779cce0ef9SKristof Provost	ipfw module. Dummynet can now be used by pf as well as ipfw. As such
789cce0ef9SKristof Provost	users who relied on this dependency may need to include ipfw in the
799cce0ef9SKristof Provost	list of modules to load on their systems.
809cce0ef9SKristof Provost
819cce0ef9SKristof Provost20210922:
820e94a306SHans Petter Selasky	As of commit 903873ce1560, the mixer(8) utility has got a slightly
8390f6610bSHans Petter Selasky	new syntax. Please refer to the mixer(8) manual page for more
848bc5971bSHans Petter Selasky	information. The old mixer utility can be installed from ports:
858bc5971bSHans Petter Selasky	audio/freebsd-13-mixer
860e94a306SHans Petter Selasky
87ae87a08cSRick Macklem20210911:
88ae87a08cSRick Macklem	As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has
89ae87a08cSRick Macklem	been deleted from the nfscommon.ko.  As such, nfsd.ko must be built
90ae87a08cSRick Macklem	from up to date sources to avoid an undefined reference when
91ae87a08cSRick Macklem	being loaded.
92ae87a08cSRick Macklem
93671a35b1SJohn Baldwin20210817:
94671a35b1SJohn Baldwin	As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS
95671a35b1SJohn Baldwin	by default.  Users can enable kernel TLS via the "KTLS" SSL
96671a35b1SJohn Baldwin	option.  This can be enabled globally by using a custom
97671a35b1SJohn Baldwin	OpenSSL config file via OPENSSL_CONF or via an
98671a35b1SJohn Baldwin	application-specific configuration option for applications
99671a35b1SJohn Baldwin	which permit setting SSL options via SSL_CONF_cmd(3).
100671a35b1SJohn Baldwin
101a3ff18e2SRick Macklem20210811:
102a3ff18e2SRick Macklem	Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS
103a3ff18e2SRick Macklem	modules. Therefore, all need to be rebuilt from sources.
104a3ff18e2SRick Macklem
10534129003SKristof Provost20210730:
10634129003SKristof Provost	Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl.
10734129003SKristof Provost	As of be70c7a50d32 it is no longer used by userspace, but it does mean
10834129003SKristof Provost	users may not be able to enumerate pf states if they update the kernel
109a191b401SKristof Provost	past b69019c14cd8 without first updating userspace past be70c7a50d32.
11034129003SKristof Provost
111728958fbSKristof Provost20210729:
112728958fbSKristof Provost	As of commit 01ad0c007964 if_bridge member interfaces can no longer
113728958fbSKristof Provost	change their MTU. Changing the MTU of the bridge itself will change the
114728958fbSKristof Provost	MTU on all member interfaces instead.
115728958fbSKristof Provost
1167fa21b6dSRick Macklem20210716:
1177fa21b6dSRick Macklem	Commit ee29e6f31111 changed the internal KAPI between the nfscommon
1187fa21b6dSRick Macklem	and nfsd modules. Therefore, both need to be rebuilt from sources.
1197fa21b6dSRick Macklem	Bump __FreeBSD_version to 1400026 for this KAPI change.
1207fa21b6dSRick Macklem
1215ede4fc0SWarner Losh20210715:
1225ede4fc0SWarner Losh	The 20210707 awk update brought in a change in behavior. This has
1235ede4fc0SWarner Losh	been corrected as of d4d252c49976. Between these dates, if you
1245ede4fc0SWarner Losh	installed a new awk binary, you may not be able to build a new
1255ede4fc0SWarner Losh	kernel because the change in behavior affected the genoffset
1265ede4fc0SWarner Losh	script used to build the kernel. If you did update, the fix is
1275ede4fc0SWarner Losh	to update your sources past the above hash and do
1285ede4fc0SWarner Losh		% cd usr.bin/awk
1295ede4fc0SWarner Losh		% make clean all
1305ede4fc0SWarner Losh		% sudo -E make install
1315ede4fc0SWarner Losh	to enable building kernels again.
1325ede4fc0SWarner Losh
133bd597b81SRick Macklem20210708:
134bd597b81SRick Macklem	Commit 1e0a518d6548 changed the internal KAPI between the NFS
135bd597b81SRick Macklem	modules. They all need to be rebuilt from sources.  I did not
136bd597b81SRick Macklem	bump __FreeBSD_version, since it was bumped recently.
137bd597b81SRick Macklem
1383f7b2317SWarner Losh20210707:
139a65fe39dSWarner Losh	awk has been updated to the latest one-true-awk version 20210215.
1403f7b2317SWarner Losh	This contains a number of minor bug fixes.
1413f7b2317SWarner Losh
142b49ba74dSRick Macklem20210624:
143b49ba74dSRick Macklem	The NFSv4 client now uses the highest minor version of NFSv4
144b49ba74dSRick Macklem	supported by the NFSv4 server by default instead of minor version 0,
145b49ba74dSRick Macklem	for NFSv4 mounts.
146b49ba74dSRick Macklem	The "minorversion" mount option may be used to override this default.
147b49ba74dSRick Macklem
14841dfd8bdSBjoern A. Zeeb20210618:
14941dfd8bdSBjoern A. Zeeb	Bump __FreeBSD_version to 1400024 for LinuxKPI changes.
150800e82d1SMaigurs Stalidzans	Most notably netdev.h can change now as the (last) dependencies
15141dfd8bdSBjoern A. Zeeb	(mlx4/ofed) are now using struct ifnet directly, but also for PCI
15241dfd8bdSBjoern A. Zeeb	additions and others.
15341dfd8bdSBjoern A. Zeeb
15441dfd8bdSBjoern A. Zeeb20210618:
15564e6e1e4SCeri Davies	The directory "blacklisted" under /usr/share/certs/ has been
15664e6e1e4SCeri Davies	renamed to "untrusted".
15764e6e1e4SCeri Davies
1585860696eSRick Macklem20210611:
1597cf9caf2SWarner Losh	svnlite has been removed from base. Should you need svn for any reason
1607cf9caf2SWarner Losh	please install the svn package or port.
1617cf9caf2SWarner Losh
1627cf9caf2SWarner Losh20210611:
1635860696eSRick Macklem	Commit e1a907a25cfa changed the internal KAPI between the krpc
1645860696eSRick Macklem	and nfsserver.  As such, both modules must be rebuilt from
1655860696eSRick Macklem	sources.  Bump __FreeBSD_version to 1400022.
1665860696eSRick Macklem
1677cf9caf2SWarner Losh20210610:
1687cf9caf2SWarner Losh	The an(4) driver has been removed from FreeBSD.
1697cf9caf2SWarner Losh
170b3823943SWarner Losh20210608:
171f530cce5SEd Maste	The vendor/openzfs branch was renamed to vendor/openzfs/legacy to
172b3823943SWarner Losh	start tracking OpenZFS upstream more closely. Please see
173b3823943SWarner Loshhttps://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html
174b3823943SWarner Losh	for details on how to correct any errors that might result. The
175b3823943SWarner Losh	short version is that you need to remove the old branch locally:
176b3823943SWarner Losh	    git update-ref -d refs/remotes/freebsd/vendor/openzfs
177b3823943SWarner Losh	(assuming your upstream origin is named 'freebsd').
178b3823943SWarner Losh
179d72cd275SBjoern A. Zeeb20210525:
180d72cd275SBjoern A. Zeeb	Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI
181d72cd275SBjoern A. Zeeb	which break drm-kmod.  In addition various other additions where
182d72cd275SBjoern A. Zeeb	comitted. Bump __FreeBSD_version to 1400015 to be able to detect this.
183d72cd275SBjoern A. Zeeb
1841c2ab28fSEmmanuel Vadot20210513:
1851c2ab28fSEmmanuel Vadot	Commit ca179c4d74f2 changed the package in which the OpenSSL
1861c2ab28fSEmmanuel Vadot	libraries and utilities are packaged.
18728ce2012SEmmanuel Vadot	It is recommended for pkgbase user to do:
1881c2ab28fSEmmanuel Vadot	pkg install -f FreeBSD-openssl
1891c2ab28fSEmmanuel Vadot	before pkg upgrade otherwise some dependencies might not be met
1901c2ab28fSEmmanuel Vadot	and pkg will stop working as libssl will not be present anymore
1911c2ab28fSEmmanuel Vadot	on the system.
1921c2ab28fSEmmanuel Vadot
19301bad87aSRick Macklem20210426:
19401bad87aSRick Macklem	Commit 875977314881 changed the internal KAPI between
19501bad87aSRick Macklem	the nfsd and nfscommon modules.  As such these modules
19601bad87aSRick Macklem	need to be rebuilt from sources.
19701bad87aSRick Macklem	Without this patch in your NFSv4.1/4.2 server, enabling
19801bad87aSRick Macklem	delegations by setting vfs.nfsd.issue_delegations non-zero
19901bad87aSRick Macklem	is not recommended.
20001bad87aSRick Macklem
20168b7d9b5SRick Macklem20210411:
20268b7d9b5SRick Macklem	Commit 7763814fc9c2 changed the internal KAPI between
20368b7d9b5SRick Macklem	the krpc and NFS.  As such, the krpc, nfscommon and
20468b7d9b5SRick Macklem	nfscl modules must all be rebuilt from sources.
205d647d0d4SRick Macklem	Without this patch, NFSv4.1/4.2 mounts should not
206d647d0d4SRick Macklem	be done with the nfscbd(8) daemon running, to avoid
207d647d0d4SRick Macklem	needing a working back channel for server->client RPCs.
20868b7d9b5SRick Macklem
2092b98ea2eSRick Macklem20210330:
2102b98ea2eSRick Macklem	Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it
2112b98ea2eSRick Macklem	handles binding of the back channel as required by RFC5661.
2122b98ea2eSRick Macklem	Until this patch is in your server, avoid use of the "nconnects"
2132b98ea2eSRick Macklem	mount option for Linux NFSv4.1/4.2 mounts.
2142b98ea2eSRick Macklem
215ba7ede0bSEd Maste20210225:
216ba7ede0bSEd Maste	For 64-bit architectures the base system is now built with Position
217ba7ede0bSEd Maste	Independent Executable (PIE) support enabled by default.  It may be
218ba7ede0bSEd Maste	disabled using the WITHOUT_PIE knob.  A clean build is required.
219ba7ede0bSEd Maste
220d386f3a3SBjoern A. Zeeb20210128:
221d386f3a3SBjoern A. Zeeb	Various LinuxKPI functionality was added which conflicts with DRM.
222d386f3a3SBjoern A. Zeeb	Please update your drm-kmod port to after the __FreeBSD_verison 1400003
223d386f3a3SBjoern A. Zeeb	update.
224d386f3a3SBjoern A. Zeeb
225429c7d1aSWarner Losh20210108:
226429c7d1aSWarner Losh	PC Card attachments for all devices have been removed. In the case of
227429c7d1aSWarner Losh	wi and cmx, the entire drivers were removed because they were only
228429c7d1aSWarner Losh	PC Card devices. FreeBSD_version 1300134 should be used for this
229429c7d1aSWarner Losh	since it was bumped so recently.
230429c7d1aSWarner Losh
23181098ca8SVladimir Kondratyev20210107:
232a84b0e94SVladimir Kondratyev	Transport-independent parts of HID support have been split off the USB
233a84b0e94SVladimir Kondratyev	code in to separate subsystem.  Kernel configs which include one of
234a84b0e94SVladimir Kondratyev	ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should
235a84b0e94SVladimir Kondratyev	be updated with adding of "device hid" line.
236a84b0e94SVladimir Kondratyev
237009c1100SBaptiste Daroussin20210105:
238bed70f83SBaptiste Daroussin	ncurses installation has been modified to only keep the widechar
239bed70f83SBaptiste Daroussin	enabled version.  Incremental build is broken for that change, so it
240bed70f83SBaptiste Daroussin	requires a clean build.
241bed70f83SBaptiste Daroussin
242878d5341SWarner Losh20201223:
243878d5341SWarner Losh	The FreeBSD project has migrated from Subversion to Git. Temporary
244878d5341SWarner Losh	instructions can be found at
245878d5341SWarner Losh	https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md

248228e2087SPedro F. Giffuni20201216:
249228e2087SPedro F. Giffuni	The services database has been updated to cover more of the basic
250228e2087SPedro F. Giffuni	services expected in a modern system. The database is big enough
251228e2087SPedro F. Giffuni	that it will cause issues in mergemaster in Releases previous to
252228e2087SPedro F. Giffuni	12.2 and 11.3, or in very old current systems from before r358154.
253228e2087SPedro F. Giffuni
2541c0ea326SEd Maste20201215:
2551c0ea326SEd Maste	Obsolete in-tree GDB 6.1.1 has been removed.  GDB (including kgdb)
2561c0ea326SEd Maste	may be installed from ports or packages.
2571c0ea326SEd Maste
2583cde9171SAlan Somers20201124:
2593cde9171SAlan Somers	ping6 has been merged into ping.  It can now be called as "ping -6".
2603cde9171SAlan Somers	See ping(8) for details.

2622d398241SAlexander V. Chernikov20201108:
2632d398241SAlexander V. Chernikov	Default value of net.add_addr_allfibs has been changed to 0.
2642d398241SAlexander V. Chernikov	If you have multi-fib configuration and rely on existence of all
2652d398241SAlexander V. Chernikov	interface routes in every fib, you need to set the above sysctl to 1.
266993d2d4bSJens Schweikhardt
267a97cfe08SStefan Eßer20201030:
2687afa1a75SStefan Eßer	The internal pre-processor in the calendar(1) program has been
2697afa1a75SStefan Eßer	extended to support more C pre-processor commands (e.g. #ifdef, #else,
2707afa1a75SStefan Eßer	and #undef) and to detect unbalanced conditional statements.
2717afa1a75SStefan Eßer	Error messages have been extended to include the filename and line
2727afa1a75SStefan Eßer	number if processing stops to help fixing malformed data files.
2737afa1a75SStefan Eßer
274a97cfe08SStefan Eßer20201026:
275d20d6550SWarner Losh	All the data files for the calendar(1) program, except calendar.freebsd,

307de209fe1SRyan Moeller
308de209fe1SRyan Moeller	Pool auto import behavior at boot has been moved from the kernel module
309de209fe1SRyan Moeller	to an explicit "zpool import -a" in one of the rc scripts enabled by
310de209fe1SRyan Moeller	zfs_enable=YES. This means your non-root zpools won't auto import until

33933176cdcSWarner Losh20200807:
34033176cdcSWarner Losh	Makefile.inc has been updated to work around the issue documented in
34133176cdcSWarner Losh	20200729. It was a case where the optimization of using symbolic links

556854cab51SCy Schubert20190913:
557854cab51SCy Schubert	ntpd no longer by default locks its pages in memory, allowing them
558854cab51SCy Schubert	to be paged out by the kernel. Use rlimit memlock to restore
559854cab51SCy Schubert	historic BSD behaviour. For example, add "rlimit memlock 32"
560854cab51SCy Schubert	to ntp.conf to lock up to 32 MB of ntpd address space in memory.

562208ae7b7SAlan Somers20190823:
563208ae7b7SAlan Somers	Several of ping6's options have been renamed for better consistency
564208ae7b7SAlan Somers	with ping.  If you use any of -ARWXaghmrtwx, you must update your

567a63915c2SAlan Somers20190727:
568bad4c94dSAlan Somers	The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls
569bad4c94dSAlan Somers	and the "-o sync_unmount" and "-o init_backgrounded" mount options have
570bad4c94dSAlan Somers	been removed from mount_fusefs(8).  You can safely remove them from
571bad4c94dSAlan Somers	your scripts, because they had no effect.
572bad4c94dSAlan Somers
573fcefa6efSAlan Somers	The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize,

579fbcfc75aSIan Lepore20190713:
580a97202f1SIan Lepore	Default permissions on the /var/account/acct file (and copies of it
581a97202f1SIan Lepore	rotated by periodic daily scripts) are changed from 0644 to 0640
582a97202f1SIan Lepore	because the file contains sensitive information that should not be
583a97202f1SIan Lepore	world-readable.  If the /var/account directory must be created by
584a97202f1SIan Lepore	rc.d/accounting, the mode used is now 0750.  Admins who use the
585a97202f1SIan Lepore	accounting feature are encouraged to change the mode of an existing

58958b5b90dSConrad Meyer	Entropy collection and the /dev/random device are no longer optional
59058b5b90dSConrad Meyer	components.  The "device random" option has been removed.
591c363b16cSConrad Meyer	Implementations of distilling algorithms can still be made loadable

6014c62bffeSBjoern A. Zeeb	A fix was applied to i386 kernel modules to avoid panics with
6024c62bffeSBjoern A. Zeeb	dpcpu or vnet.  Users need to recompile i386 kernel modules
6034c62bffeSBjoern A. Zeeb	having pcpu or vnet sections or they will refuse to load.

605aa0a8933SMark Johnston20190513:
606aa0a8933SMark Johnston	User-wired pages now have their own counter,
607aa0a8933SMark Johnston	vm.stats.vm.v_user_wire_count.  The vm.max_wired sysctl was renamed
608aa0a8933SMark Johnston	to vm.max_user_wired and changed from an unsigned int to an unsigned
609aa0a8933SMark Johnston	long.  bhyve VMs wired with the -S are now subject to the user
610aa0a8933SMark Johnston	wiring limit; the vm.max_user_wired sysctl may need to be tuned to
611aa0a8933SMark Johnston	avoid running into the limit.

613251a32b5SKyle Evans20190507:
614542970faSAndrew Gallatin	The IPSEC option has been removed from GENERIC.  Users requiring
615542970faSAndrew Gallatin	ipsec(4) must now load the ipsec(4) kernel module.
616542970faSAndrew Gallatin
617542970faSAndrew Gallatin20190507:
618251a32b5SKyle Evans	The tap(4) driver has been folded into tun(4), and the module has been
61915e9beb7SKyle Evans	renamed to tuntap.  You should update any kld_list="if_tap" or
62015e9beb7SKyle Evans	kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or
621251a32b5SKyle Evans	if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap
622251a32b5SKyle Evans	module instead, and "device tap" or "device tun" entries in kernel

6253782136fSConrad Meyer20190418:
6263782136fSConrad Meyer	The following knobs have been added related to tradeoffs between
6273782136fSConrad Meyer	safe use of the random device and availability in the absence of
6283782136fSConrad Meyer	entropy:
6293782136fSConrad Meyer
6303782136fSConrad Meyer	kern.random.initial_seeding.bypass_before_seeding: tunable; set
6313782136fSConrad Meyer	non-zero to bypass the random device prior to seeding, or zero to
6323782136fSConrad Meyer	block random requests until the random device is initially seeded.
6333782136fSConrad Meyer	For now, set to 1 (unsafe) by default to restore pre-r346250 boot
6343782136fSConrad Meyer	availability properties.
6353782136fSConrad Meyer
6363782136fSConrad Meyer	kern.random.initial_seeding.read_random_bypassed_before_seeding:
6373782136fSConrad Meyer	read-only diagnostic sysctl that is set when bypass is enabled and
6383782136fSConrad Meyer	read_random(9) is bypassed, to enable programmatic handling of this
6393782136fSConrad Meyer	initial condition, if desired.
6403782136fSConrad Meyer
6413782136fSConrad Meyer	kern.random.initial_seeding.arc4random_bypassed_before_seeding:
6423782136fSConrad Meyer	Similar to the above, but for for arc4random(9) initial seeding.
6433782136fSConrad Meyer
6443782136fSConrad Meyer	kern.random.initial_seeding.disable_bypass_warnings: tunable; set
6453782136fSConrad Meyer	non-zero to disable warnings in dmesg when the same conditions are
6463782136fSConrad Meyer	met as for the diagnostic sysctls above.  Defaults to zero, i.e.,
6473782136fSConrad Meyer	produce warnings in dmesg when the conditions are met.
6483782136fSConrad Meyer
649f3d2512dSConrad Meyer20190416:
650f3d2512dSConrad Meyer	The loadable random module KPI has changed; the random_infra_init()
651f3d2512dSConrad Meyer	routine now requires a 3rd function pointer for a bool (*)(void)
652f3d2512dSConrad Meyer	method that returns true if the random device is seeded (and
653f3d2512dSConrad Meyer	therefore unblocked).

655bcf55f64SRick Macklem20190404:
656bcf55f64SRick Macklem	r345895 reverts r320698. This implies that an nfsuserd(8) daemon
657bcf55f64SRick Macklem	built from head sources between r320757 (July 6, 2017) and
658bcf55f64SRick Macklem	r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock"
659bcf55f64SRick Macklem	is added to the command line.
660bcf55f64SRick Macklem	nfsuserd daemons built from head sources that are post-r338192 are
661bcf55f64SRick Macklem	not affected and should continue to work.
662bcf55f64SRick Macklem
663123af6ecSAlan Somers20190320:
664123af6ecSAlan Somers	The fuse(4) module has been renamed to fusefs(4) for consistency with
665123af6ecSAlan Somers	other filesystems.  You should update any kld_load="fuse" entries in
666123af6ecSAlan Somers	/etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and
66782455a33SJens Schweikhardt	"options FUSE" entries in kernel config files.

685c75f49f7SKonstantin Belousov20190131:
686c75f49f7SKonstantin Belousov	Iflib is no longer unconditionally compiled into the kernel.  Drivers
687c75f49f7SKonstantin Belousov	using iflib and statically compiled into the kernel, now require
688c75f49f7SKonstantin Belousov	the 'device iflib' config option.  For the same drivers loaded as

69883a41dd0SRebecca Cran20181230:
69983a41dd0SRebecca Cran	r342635 changes the way efibootmgr(8) works by requiring users to add
70083a41dd0SRebecca Cran	the -b (bootnum) parameter for commands where the bootnum was previously
70183a41dd0SRebecca Cran	specified with each option. For example 'efibootmgr -B 0001' is now

704d493fe42SRick Macklem20181220:
705d493fe42SRick Macklem	r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport
706d493fe42SRick Macklem	in the same as it is applied to NFSv2 and 3.  This implies that NFSv4
707d493fe42SRick Macklem	servers that have vfs.nfsd.nfs_privport set will only allow mounts
708857cde69SMaigurs Stalidzans	from clients using a reserved port. Since both the FreeBSD and Linux
709857cde69SMaigurs Stalidzans	NFSv4 clients use reserved ports by default, this should not affect
710d493fe42SRick Macklem	most NFSv4 mounts.

712beab3c4bSWarner Losh20181219:
71331733a7dSWarner Losh	The XLP config has been removed. We can't support 64-bit atomics in this
71431733a7dSWarner Losh	kernel because it is running in 32-bit mode. XLP users must transition
71531733a7dSWarner Losh	to running a 64-bit kernel (XLP64 or XLPN32).
71631733a7dSWarner Losh
71731733a7dSWarner Losh	The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is
71831733a7dSWarner Losh	the preferred emulator today and we don't need two different ones.
71931733a7dSWarner Losh
7200bb183edSWarner Losh	The old sibyte / swarm / Broadcom BCM1250 support has been

73930c5db2bSAndrew Turner20181123:
74030c5db2bSAndrew Turner	The BSD crtbegin and crtend code has been enabled by default. It has
74130c5db2bSAndrew Turner	had extensive testing on amd64, arm64, and i386. It can be disabled

760468002c5SWarner Losh20181015:
761468002c5SWarner Losh	Ports for the DRM modules have been simplified. Now, amd64 users should
762468002c5SWarner Losh	just install the drm-kmod port. All others should install
763468002c5SWarner Losh	drm-legacy-kmod.
764468002c5SWarner Losh
765468002c5SWarner Losh	Graphics hardware that's newer than about 2010 usually works with
766468002c5SWarner Losh	drm-kmod.  For hardware older than 2013, however, some users will need
767468002c5SWarner Losh	to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older
768468002c5SWarner Losh	than 2008 usually only works in drm-legacy-kmod. The graphics team can
769468002c5SWarner Losh	only commit to hardware made since 2013 due to the complexity of the
770468002c5SWarner Losh	market and difficulty to test all the older cards effectively. If you
771468002c5SWarner Losh	have hardware supported by drm-kmod, you are strongly encouraged to use
772468002c5SWarner Losh	that as you will get better support.
773468002c5SWarner Losh
774468002c5SWarner Losh	Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined
775468002c5SWarner Losh	elsewhere, the drm and drm2 modules will be eliminated from the src base
776274cfcd7SWarner Losh	soon (with a limited exception for arm). Please update to the package
777274cfcd7SWarner Losh	asap and report any issues to x11@freebsd.org.
778468002c5SWarner Losh
779468002c5SWarner Losh	Generally, anybody using the drm*-kmod packages should add
780468002c5SWarner Losh	WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty
781468002c5SWarner Losh	cross-threading surprises, especially with automatic driver
782468002c5SWarner Losh	loading from X11 startup. These will become the defaults in 13-current

785b34bb3bfSMarius Strobl20181012:
786b34bb3bfSMarius Strobl	The ixlv(4) driver has been renamed to iavf(4).  As a consequence,
787b34bb3bfSMarius Strobl	custom kernel and module loading configuration files must be updated
788b34bb3bfSMarius Strobl	accordingly.  Moreover, interfaces previous presented as ixlvN to the

82119fa89e9SMark Murray	The Yarrow CSPRNG has been removed from the kernel as it has not been
82219fa89e9SMark Murray	supported by its designers since at least 2003. Fortuna has been the
82319fa89e9SMark Murray	default since FreeBSD-11.

8250fb707ecSWarner Losh20180822:
8260fb707ecSWarner Losh	devctl freeze/thaw have gone into the tree, the rc scripts have been
82784b9dfe4SWarner Losh	updated to use them and devmatch has been changed.  You should update
82884b9dfe4SWarner Losh	kernel, userland and rc scripts all at the same time.

830f9f8ac94SKyle Evans20180818:
831f9f8ac94SKyle Evans	The default interpreter has been switched from 4th to Lua.
832f9f8ac94SKyle Evans	LOADER_DEFAULT_INTERP, documented in build(7), will override the default
833f9f8ac94SKyle Evans	interpreter.  If you have custom FORTH code you will need to set
834f9f8ac94SKyle Evans	LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in
835f9f8ac94SKyle Evans	src.conf for the build.  This will create default hard links between
836f9f8ac94SKyle Evans	loader and loader_4th instead of loader and loader_lua, the new default.
837f9f8ac94SKyle Evans	If you are using UEFI it will create the proper hard link to loader.efi.
838f9f8ac94SKyle Evans
839295506bfSWarner Losh	bhyve uses userboot.so. It remains 4th-only until some issues are solved
840295506bfSWarner Losh	regarding coexisting with multiple versions of FreeBSD are resolved.

84272ad696aSKyle Evans20180815:
84372ad696aSKyle Evans	ls(1) now respects the COLORTERM environment variable used in other
84472ad696aSKyle Evans	systems and software to indicate that a colored terminal is both
84572ad696aSKyle Evans	supported and desired.  If ls(1) is suddenly emitting colors, they may
846e10ba800SKyle Evans	be disabled again by either removing the unwanted COLORTERM from your
847e10ba800SKyle Evans	environment, or using `ls --color=never`.  The ls(1) specific CLICOLOR
848e10ba800SKyle Evans	may not be observed in a future release.

85047cc9ee1SAlan Somers20180808:
85147cc9ee1SAlan Somers	The default pager for most commands has been changed to "less".  To
85247cc9ee1SAlan Somers	restore the old behavior, set PAGER="more" and MANPAGER="more -s" in
85347cc9ee1SAlan Somers	your environment.

855b5988450SRavi Pokala20180731:
856b5988450SRavi Pokala	The jedec_ts(4) driver has been removed. A superset of its functionality
857b5988450SRavi Pokala	is available in the jedec_dimm(4) driver, and the manpage for that
858b5988450SRavi Pokala	driver includes migration instructions. If you have "device jedec_ts"
859b5988450SRavi Pokala	in your kernel configuration file, it must be removed.

861164138e7SKyle Evans20180730:
862164138e7SKyle Evans	amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default.
863dfa6eec2SKyle Evans	This should have no effect if the kernel is booted via BIOS/legacy boot.
8641ddc8a8eSKyle Evans	EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system
865164138e7SKyle Evans	has a buggy firmware that prevents a successful boot due to use of
866164138e7SKyle Evans	runtime services.

873b43c6042SWarner Losh20180723:
874b43c6042SWarner Losh	loader.efi has been augmented to participate more fully in the
875663472dfSWarner Losh	UEFI boot manager protocol. loader.efi will now look at the
876663472dfSWarner Losh	BootXXXX environment variable to determine if a specific kernel
877663472dfSWarner Losh	or root partition was specified. XXXX is derived from BootCurrent.
878663472dfSWarner Losh	efibootmgr(8) manages these standard UEFI variables.

880d397afa3SWarner Losh20180720:
881d397afa3SWarner Losh	zfsloader's functionality has now been folded into loader.
8825f9d7aafSEd Maste	zfsloader is no longer necessary once you've updated your
8833b741022SWarner Losh	boot blocks. For a transition period, we will install a
8843b741022SWarner Losh	hardlink for zfsloader to loader to allow a smooth transition
8853b741022SWarner Losh	until the boot blocks can be updated (hard link because old
8863b741022SWarner Losh	zfs boot blocks don't understand symlinks).

888d0e46652SIan Lepore20180719:
889c59a544eSEmmanuel Vadot	ARM64 now have efifb support, if you want to have serial console
890c59a544eSEmmanuel Vadot	on your arm64 board when an screen is connected and the bootloader
891deb17a3bSWarner Losh	setup a frame buffer for us to use, just add :
892c59a544eSEmmanuel Vadot	boot_serial=YES
893c59a544eSEmmanuel Vadot	boot_multicons=YES
894c59a544eSEmmanuel Vadot	in /boot/loader.conf
895c59a544eSEmmanuel Vadot	For Raspberry Pi 3 (RPI) users, this is needed even if you don't have
896c59a544eSEmmanuel Vadot	an screen connected as the firmware will setup a frame buffer are that
897c59a544eSEmmanuel Vadot	u-boot will expose as an EFI frame buffer.

899c59a544eSEmmanuel Vadot20180719:
900d0e46652SIan Lepore	New uid:gid added, ntpd:ntpd (123:123).  Be sure to run mergemaster
901d0e46652SIan Lepore	or take steps to update /etc/passwd before doing installworld on
9020d77d170SIan Lepore	existing systems.  Do not skip the "mergemaster -Fp" step before
9030d77d170SIan Lepore	installworld, as described in the update procedures near the bottom
9040d77d170SIan Lepore	of this document.  Also, rc.d/ntpd now starts ntpd(8) as user ntpd
905d0e46652SIan Lepore	if the new mac_ntpd(4) policy is available, unless ntpd_flags or
906d0e46652SIan Lepore	the ntp config file contain options that change file/dir locations.
907d0e46652SIan Lepore	When such options (e.g., "statsdir" or "crypto") are used, ntpd can
908d0e46652SIan Lepore	still be run as non-root by setting ntpd_user=ntpd in rc.conf, after
909d0e46652SIan Lepore	taking steps to ensure that all required files/dirs are accessible
910d0e46652SIan Lepore	by the ntpd user.

91544314c35SKyle Evans20180711:
91644314c35SKyle Evans	The static environment setup in kernel configs is no longer mutually
91744314c35SKyle Evans	exclusive with the loader(8) environment by default.  In order to
91844314c35SKyle Evans	restore the previous default behavior of disabling the loader(8)
91944314c35SKyle Evans	environment if a static environment is present, you must specify
92044314c35SKyle Evans	loader_env.disabled=1 in the static environment.
92144314c35SKyle Evans
922f38b68aeSBrooks Davis20180705:
923f38b68aeSBrooks Davis	The ABI of syscalls used by management tools like sockstat and
924f38b68aeSBrooks Davis	netstat has been broken to allow 32-bit binaries to work on
925f38b68aeSBrooks Davis	64-bit kernels without modification.  These programs will need
926f38b68aeSBrooks Davis	to match the kernel in order to function.  External programs may
927f38b68aeSBrooks Davis	require minor modifications to accommodate a change of type in
928f38b68aeSBrooks Davis	structures from pointers to 64-bit virtual addresses.

930f4b36404SMatt Macy20180702:
931f4b36404SMatt Macy	On i386 and amd64 atomics are now inlined. Out of tree modules using
932f4b36404SMatt Macy	atomics will need to be rebuilt.
933f4b36404SMatt Macy
9340dea6e3cSMariusz Zaborski20180701:
9350dea6e3cSMariusz Zaborski	The '%I' format in the kern.corefile sysctl limits the number of
9360dea6e3cSMariusz Zaborski	core files that a process can generate to the number stored in the
9370dea6e3cSMariusz Zaborski	debug.ncores sysctl. The '%I' format is replaced by the single digit
9380dea6e3cSMariusz Zaborski	index. Previously, if all indexes were taken the kernel would overwrite
9390dea6e3cSMariusz Zaborski	only a core file with the highest index in a filename.
9400dea6e3cSMariusz Zaborski	Currently the system will create a new core file if there is a free
9410dea6e3cSMariusz Zaborski	index or if all slots are taken it will overwrite the oldest one.

9492fd8cef4SWarner Losh20180628:
9502fd8cef4SWarner Losh	r335753 introduced a new quoting method. However, etc/devd/devmatch.conf
9512fd8cef4SWarner Losh	needed to be changed to work with it. This change was made with r335763
952274cfcd7SWarner Losh	and requires a mergemaster / etcupdate / etc to update the installed

955fa986e33SRick Macklem20180612:
956fa986e33SRick Macklem	r334930 changed the interface between the NFS modules, so they all

9590bf7cdd5SWarner Losh20180530:
9606f282e72SEd Maste	As of r334391 lld is the default amd64 system linker; it is installed
9616f282e72SEd Maste	as /usr/bin/ld.  Kernel build workarounds (see 20180510 entry) are no
9626f282e72SEd Maste	longer necessary.

9646f282e72SEd Maste20180530:
9650bf7cdd5SWarner Losh	The kernel / userland interface for devinfo changed, so you'll
9660bf7cdd5SWarner Losh	need a new kernel and userland as a pair for it to work (rebuilding
9670bf7cdd5SWarner Losh	lib/libdevinfo is all that's required). devinfo and devmatch will
9680bf7cdd5SWarner Losh	not work, but everything else will when there's a mismatch.
9690bf7cdd5SWarner Losh
9707e1a13f4SMatt Macy20180523:
9717e1a13f4SMatt Macy	The on-disk format for hwpmc callchain records has changed to include
9727e1a13f4SMatt Macy	threadid corresponding to a given record. This changes the field offsets
9737e1a13f4SMatt Macy	and thus requires that libpmcstat be rebuilt before using a kernel
9747e1a13f4SMatt Macy	later than r334108.
9757e1a13f4SMatt Macy
9766f78fad3SSean Bruno20180517:
9776f78fad3SSean Bruno	The vxge(4) driver has been removed.  This driver was introduced into
9786f78fad3SSean Bruno	HEAD one week before the Exar left the Ethernet market and is not
9796f78fad3SSean Bruno	known to be used.  If you have device vxge in your kernel config file
9806f78fad3SSean Bruno	it must be removed.
9816f78fad3SSean Bruno
9826e258ed3SWarner Losh20180510:
983eb8831b9SWarner Losh	The amd64 kernel now requires a ld that supports ifunc to produce a
984eb8831b9SWarner Losh	working kernel, either lld or a newer binutils. lld is built by default
985eb8831b9SWarner Losh	on amd64, and the 'buildkernel' target uses it automatically. However,
986eb8831b9SWarner Losh	it is not the default linker, so building the kernel the traditional
987eb8831b9SWarner Losh	way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for
988eb8831b9SWarner Losh	binutils port/package). lld will soon be default, and this requirement
989eb8831b9SWarner Losh	will go away.
990eb8831b9SWarner Losh
9916f282e72SEd Maste	NOTE: As of r334391 lld is the default system linker on amd64, and no
9926f282e72SEd Maste	workaround is necessary.

99457b49365SSean Bruno20180508:
99557b49365SSean Bruno	The nxge(4) driver has been removed.  This driver was for PCI-X 10g
99682455a33SJens Schweikhardt	cards made by s2io/Neterion.  The company was acquired by Exar and
99757b49365SSean Bruno	no longer sells or supports Ethernet products.  If you have device
99857b49365SSean Bruno	nxge in your kernel config file it must be removed.
99957b49365SSean Bruno
1000ba3833a8SPhilip Paeps20180504:
1001ba3833a8SPhilip Paeps	The tz database (tzdb) has been updated to 2018e.  This version more
1002ba3833a8SPhilip Paeps	correctly models time stamps in time zones with negative DST such as
1003ba3833a8SPhilip Paeps	Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and
1004ba3833a8SPhilip Paeps	Africa/Windhoek (1994/2017).  This does not affect the UT offsets, only
1005ba3833a8SPhilip Paeps	time zone abbreviations and the tm_isdst flag.
1006ba3833a8SPhilip Paeps
10072695c9c1SSean Bruno20180502:
10082695c9c1SSean Bruno	The ixgb(4) driver has been removed.  This driver was for an early and
10092695c9c1SSean Bruno	uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel
10102695c9c1SSean Bruno	quickly shifted to the long lived ixgbe family.  If you have device
10112695c9c1SSean Bruno	ixgb in your kernel config file it must be removed.
10122695c9c1SSean Bruno
1013e6a376d1SEd Maste20180501:
1014e6a376d1SEd Maste	The lmc(4) driver has been removed.  This was a WAN interface
1015e6a376d1SEd Maste	card that was already reportedly rare in 2003, and had an ambiguous
1016e6a376d1SEd Maste	license.  If you have device lmc in your kernel config file it must
1017e6a376d1SEd Maste	be removed.
1018e6a376d1SEd Maste
10193a4fc8a8SBrooks Davis20180413:
10203a4fc8a8SBrooks Davis	Support for Arcnet networks has been removed.  If you have device
10213a4fc8a8SBrooks Davis	arcnet or device cm in your kernel config file they must be
10223a4fc8a8SBrooks Davis	removed.
10233a4fc8a8SBrooks Davis
10240437c8e3SBrooks Davis20180411:
10250437c8e3SBrooks Davis	Support for FDDI networks has been removed.  If you have device
10260437c8e3SBrooks Davis	fddi or device fpa in your kernel config file they must be
10270437c8e3SBrooks Davis	removed.
10280437c8e3SBrooks Davis
10298129693eSEd Schouten20180406:
10308129693eSEd Schouten	In addition to supporting RFC 3164 formatted messages, the
10318129693eSEd Schouten	syslogd(8) service is now capable of parsing RFC 5424 formatted
10328129693eSEd Schouten	log messages. The main benefit of using RFC 5424 is that clients
10338129693eSEd Schouten	may now send log messages with timestamps containing year numbers,
10348129693eSEd Schouten	microseconds and time zone offsets.
10358129693eSEd Schouten
10368129693eSEd Schouten	Similarly, the syslog(3) C library function has been altered to
10378129693eSEd Schouten	send RFC 5424 formatted messages to the local system logging
10388129693eSEd Schouten	daemon. On systems using syslogd(8), this change should have no
10398129693eSEd Schouten	negative impact, as long as syslogd(8) and the C library are
10408129693eSEd Schouten	updated at the same time. On systems using a different system
10418129693eSEd Schouten	logging daemon, it may be necessary to make configuration
10428129693eSEd Schouten	adjustments, depending on the software used.
10438129693eSEd Schouten
10448129693eSEd Schouten	When using syslog-ng, add the 'syslog-protocol' flag to local
10458129693eSEd Schouten	input sources to enable parsing of RFC 5424 formatted messages:
10468129693eSEd Schouten
10478129693eSEd Schouten		source src {
10488129693eSEd Schouten			unix-dgram("/var/run/log" flags(syslog-protocol));
10498129693eSEd Schouten		}
10508129693eSEd Schouten
10518129693eSEd Schouten	When using rsyslog, disable the 'SysSock.UseSpecialParser' option
10528129693eSEd Schouten	of the 'imuxsock' module to let messages be processed by the
10538129693eSEd Schouten	regular RFC 3164/5424 parsing pipeline:
10548129693eSEd Schouten
10558129693eSEd Schouten		module(load="imuxsock" SysSock.UseSpecialParser="off")
10568129693eSEd Schouten
10578129693eSEd Schouten	Do note that these changes only affect communication between local
10588129693eSEd Schouten	applications and syslogd(8). The format that syslogd(8) uses to
10598129693eSEd Schouten	store messages on disk or forward messages to other systems
10608129693eSEd Schouten	remains unchanged. syslogd(8) still uses RFC 3164 for these
10618129693eSEd Schouten	purposes. Options to customize this behaviour will be added in the
10628129693eSEd Schouten	future. Utilities that process log files stored in /var/log are
10638129693eSEd Schouten	thus expected to continue to function as before.
10648129693eSEd Schouten
10658129693eSEd Schouten	__FreeBSD_version has been incremented to 1200061 to denote this
10668129693eSEd Schouten	change.
10678129693eSEd Schouten
1068c53b0251SBrooks Davis20180328:
106969f0fecbSBrooks Davis	Support for token ring networks has been removed. If you
107069f0fecbSBrooks Davis	have "device token" in your kernel config you should remove
107169f0fecbSBrooks Davis	it. No device drivers supported token ring.
107269f0fecbSBrooks Davis
107372bf324cSBenno Rice20180323:
107472bf324cSBenno Rice	makefs was modified to be able to tag ISO9660 El Torito boot catalog
107572bf324cSBenno Rice	entries as EFI instead of overloading the i386 tag as done previously.
107672bf324cSBenno Rice	The amd64 mkisoimages.sh script used to build amd64 ISO images for
107772bf324cSBenno Rice	release was updated to use this. This may mean that makefs must be
107872bf324cSBenno Rice	updated before "make cdrom" can be run in the release directory. This
107972bf324cSBenno Rice	should be as simple as:
108072bf324cSBenno Rice
108172bf324cSBenno Rice		$ cd $SRCDIR/usr.sbin/makefs

1282fbcf7bcdSJustin Hibbits20170625:
1283fbcf7bcdSJustin Hibbits	The FreeBSD/powerpc platform now uses a 64-bit type for time_t.  This is
1284fbcf7bcdSJustin Hibbits	a very major ABI incompatible change, so users of FreeBSD/powerpc must

12925ab191c4SWarner Losh	Forward compatibility for the "ino64" project have been committed. This
12935ab191c4SWarner Losh	will allow most new binaries to run on older kernels in a limited
12945ab191c4SWarner Losh	fashion.  This prevents many of the common foot-shooting actions in the

12965ab191c4SWarner Losh	the ino64 upgrade. Complicated use cases may not work properly, though

1355dcfffd04SEd Maste
1356dcfffd04SEd Maste	For the safest in-place upgrade begin by removing previous build
1357359d22d4SWarner Losh	artifacts via "rm -rf /usr/obj/*".  Then, carefully follow the full
1358359d22d4SWarner Losh	procedure documented below under the heading "To rebuild everything and
1359359d22d4SWarner Losh	install it on the current system."  Specifically, a reboot is required
1360359d22d4SWarner Losh	after installing the new kernel before installing world. While an
1361359d22d4SWarner Losh	installworld normally works by accident from multiuser after rebooting

1366a25a1ff4SBrooks Davis	The NATM framework including the en(4), fatm(4), hatm(4), and
1367a25a1ff4SBrooks Davis	patm(4) devices has been removed.  Consumers should plan a

1370a17665bcSBaptiste Daroussin20170420:
1371a17665bcSBaptiste Daroussin	GNU diff has been replaced by a BSD licensed diff. Some features of GNU
1372a17665bcSBaptiste Daroussin	diff has not been implemented, if those are needed a newer version of
1373a17665bcSBaptiste Daroussin	GNU diff is available via the diffutils package under the gdiff name.

13755810e45bSCy Schubert20170413:
13765810e45bSCy Schubert	As of r316810 for ipfilter, keep frags is no longer assumed when
13775810e45bSCy Schubert	keep state is specified in a rule. r316810 aligns ipfilter with
13785810e45bSCy Schubert	documentation in man pages separating keep frags from keep state.
1379a3a09aefSJens Schweikhardt	This allows keep state to be specified without forcing keep frags
13805810e45bSCy Schubert	and allows keep frags to be specified independently of keep state.
13815810e45bSCy Schubert	To maintain previous behaviour, also specify keep frags with
13820cad3ecaSCy Schubert	keep state (as documented in ipf.conf.5).
13835810e45bSCy Schubert
13841bf5e133SEd Maste20170407:
13851bf5e133SEd Maste	arm64 builds now use the base system LLD 4.0.0 linker by default,
13861bf5e133SEd Maste	instead of requiring that the aarch64-binutils port or package be
13871bf5e133SEd Maste	installed. To continue using aarch64-binutils, set

14030458b265SEnji Cooper
14040458b265SEnji Cooper	If building cfiscsi.ko as a kernel module, the module can be loaded
14050458b265SEnji Cooper	via one of the following methods:
14060458b265SEnji Cooper	- `cfiscsi_load="YES"` in loader.conf(5).
14070458b265SEnji Cooper	- Add `cfiscsi` to `$kld_list` in rc.conf(5).

141372dec079SMarius Strobl20170316:
141472dec079SMarius Strobl	The mmcsd.ko module now additionally depends on geom_flashmap.ko.
141572dec079SMarius Strobl	Also, mmc.ko and mmcsd.ko need to be a matching pair built from the
141672dec079SMarius Strobl	same source (previously, the dependency of mmcsd.ko on mmc.ko was
141772dec079SMarius Strobl	missing, but mmcsd.ko now will refuse to load if it is incompatible
141872dec079SMarius Strobl	with mmc.ko).

14206ed14738SAndrey V. Elsukov20170315:
14216ed14738SAndrey V. Elsukov	The syntax of ipfw(8) named states was changed to avoid ambiguity.
14226ed14738SAndrey V. Elsukov	If you have used named states in the firewall rules, you need to modify
14236ed14738SAndrey V. Elsukov	them after installworld and before rebooting. Now named states must
14246ed14738SAndrey V. Elsukov	be prefixed with colon.

1507bba95d2dSMarcel Moolenaar	Relocatable object files with the extension of .So have been renamed
1508bba95d2dSMarcel Moolenaar	to use an extension of .pico instead.  The purpose of this change is
1509bba95d2dSMarcel Moolenaar	to avoid a name clash with shared libraries on case-insensitive file

1559857cde69SMaigurs Stalidzans	CAM now strips the leading spaces from each SCSI disk's serial number.
1560fb9b2ab1SBryan Drewery	This will affect users who create UFS filesystems on SCSI disks using
1561583febf4SAlan Somers	those disk's diskid device nodes.  For example, if /etc/fstab

1604a1743365SWarner Losh	data is believed to be complete, be on the lookout for data

1627497e8091SBryan Drewery20160330:
1628497e8091SBryan Drewery	The FAST_DEPEND build option has been removed and its functionality is
1629497e8091SBryan Drewery	now the one true way.  The old mkdep(1) style of 'make depend' has
1630497e8091SBryan Drewery	been removed.  See 20160311 for further details.

1632da1b038aSJustin Hibbits20160317:
1633da1b038aSJustin Hibbits	Resource range types have grown from unsigned long to uintmax_t.  All
1634da1b038aSJustin Hibbits	drivers, and anything using libdevinfo, need to be recompiled.

1636d783b170SBryan Drewery20160311:
1637d783b170SBryan Drewery	WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
1638d783b170SBryan Drewery	builds.  It no longer runs mkdep(1) during 'make depend', and the
1639d783b170SBryan Drewery	'make depend' stage can safely be skipped now as it is auto ran
1640d783b170SBryan Drewery	when building 'make all' and will generate all SRCS and DPSRCS before
1641d783b170SBryan Drewery	building anything else.  Dependencies are gathered at compile time with
1642d783b170SBryan Drewery	-MF flags kept in separate .depend files per object file.  Users should
1643d783b170SBryan Drewery	run 'make cleandepend' once if using -DNO_CLEAN to clean out older
1644d783b170SBryan Drewery	stale .depend files.

1646c834228bSDimitry Andric20160306:
1647c834228bSDimitry Andric	On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
1648c834228bSDimitry Andric	kernel modules.  Therefore, if you load any kernel modules at boot time,
1649c834228bSDimitry Andric	please install the boot loaders after you install the kernel, but before
1650c834228bSDimitry Andric	rebooting, e.g.:
1651c834228bSDimitry Andric
1652c834228bSDimitry Andric	make buildworld
1653779f392bSJohn Baldwin	make buildkernel KERNCONF=YOUR_KERNEL_HERE
1654779f392bSJohn Baldwin	make installkernel KERNCONF=YOUR_KERNEL_HERE
1655c834228bSDimitry Andric	make -C sys/boot install

1657c834228bSDimitry Andric
1658c834228bSDimitry Andric	Then follow the usual steps, described in the General Notes section,
1659c834228bSDimitry Andric	below.
1660c834228bSDimitry Andric
1661e74e149fSDimitry Andric20160305:
1662e74e149fSDimitry Andric	Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0.  Please
1663e74e149fSDimitry Andric	see the 20141231 entry below for information about prerequisites and
1664e74e149fSDimitry Andric	upgrading, if you are not already using clang 3.5.0 or higher.

16668b66d3d3SJohn Baldwin20160301:
16678b66d3d3SJohn Baldwin	The AIO subsystem is now a standard part of the kernel.  The
16688b66d3d3SJohn Baldwin	VFS_AIO kernel option and aio.ko kernel module have been removed.
16698b66d3d3SJohn Baldwin	Due to stability concerns, asynchronous I/O requests are only
16708b66d3d3SJohn Baldwin	permitted on sockets and raw disks by default.  To enable
16718b66d3d3SJohn Baldwin	asynchronous I/O requests on all file types, set the
16728b66d3d3SJohn Baldwin	vfs.aio.enable_unsafe sysctl to a non-zero value.

1674de463b29SEd Maste20160226:
1675ca8b902aSEd Maste	The ELF object manipulation tool objcopy is now provided by the
1676ca8b902aSEd Maste	ELF Tool Chain project rather than by GNU binutils. It should be a
1677ca8b902aSEd Maste	drop-in replacement, with the addition of arm64 support. The
1678ca8b902aSEd Maste	(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
1679ca8b902aSEd Maste	to obtain the GNU version if necessary.

1681d4b9233aSAlan Somers20160129:
1682d4b9233aSAlan Somers	Building ZFS pools on top of zvols is prohibited by default.  That
1683d4b9233aSAlan Somers	feature has never worked safely; it's always been prone to deadlocks.
1684d4b9233aSAlan Somers	Using a zvol as the backing store for a VM guest's virtual disk will
1685d4b9233aSAlan Somers	still work, even if the guest is using ZFS.  Legacy behavior can be
1686d4b9233aSAlan Somers	restored by setting vfs.zfs.vol.recursive=1.

168860c59fadSDag-Erling Smørgrav20160119:
168960c59fadSDag-Erling Smørgrav	The NONE and HPN patches has been removed from OpenSSH.  They are
169060c59fadSDag-Erling Smørgrav	still available in the security/openssh-portable port.

16923bf7d9a6SMarcelo Araujo20160113:
16933bf7d9a6SMarcelo Araujo	With the addition of ypldap(8), a new _ypldap user is now required
16943bf7d9a6SMarcelo Araujo	during installworld. "mergemaster -p" can be used to add the user
16953bf7d9a6SMarcelo Araujo	prior to installworld, as documented in the handbook.

16974d6ab32fSBaptiste Daroussin20151216:
16984d6ab32fSBaptiste Daroussin	The tftp loader (pxeboot) now uses the option root-path directive. As a
16994d6ab32fSBaptiste Daroussin	consequence it no longer looks for a pxeboot.4th file on the tftp
17004d6ab32fSBaptiste Daroussin	server. Instead it uses the regular /boot infrastructure as with the
17014d6ab32fSBaptiste Daroussin	other loaders.

1703ca7e5285SWarner Losh20151211:
1704ca7e5285SWarner Losh	The code to start recording plug and play data into the modules has
1705ca7e5285SWarner Losh	been committed. While the old tools will properly build a new kernel,
1706ca7e5285SWarner Losh	a number of warnings about "unknown metadata record 4" will be produced
1707ca7e5285SWarner Losh	for an older kldxref. To avoid such warnings, make sure to rebuild
1708ca7e5285SWarner Losh	the kernel toolchain (or world). Make sure that you have r292078 or
1709ca7e5285SWarner Losh	later when trying to build 292077 or later before rebuilding.

1711015dfda6SEd Maste20151207:
1712015dfda6SEd Maste	Debug data files are now built by default with 'make buildworld' and
1713015dfda6SEd Maste	installed with 'make installworld'. This facilitates debugging but
1714015dfda6SEd Maste	requires more disk space both during the build and for the installed
1715015dfda6SEd Maste	world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
1716015dfda6SEd Maste	in src.conf(5).

171833ba1088SRick Macklem20151130:
171933ba1088SRick Macklem	r291527 changed the internal interface between the nfsd.ko and
172033ba1088SRick Macklem	nfscommon.ko modules. As such, they must both be upgraded to-gether.
172133ba1088SRick Macklem	__FreeBSD_version has been bumped because of this.

1723af1d74f0SBaptiste Daroussin20151108:
1724af1d74f0SBaptiste Daroussin	Add support for unicode collation strings leads to a change of
1725af1d74f0SBaptiste Daroussin	order of files listed by ls(1) for example. To get back to the old
1726af1d74f0SBaptiste Daroussin	behaviour, set LC_COLLATE environment variable to "C".
1727af1d74f0SBaptiste Daroussin
17280492a14fSBaptiste Daroussin	Databases administrators will need to reindex their databases given
17290492a14fSBaptiste Daroussin	collation results will be different.
17300492a14fSBaptiste Daroussin
173110b5202eSBaptiste Daroussin	Due to a bug in install(1) it is recommended to remove the ancient
17321300d6f1SBaptiste Daroussin	locales before running make installworld.
173301bedb0cSBaptiste Daroussin

17367bded2dbSJung-uk Kim20151030:
17377bded2dbSJung-uk Kim	The OpenSSL has been upgraded to 1.0.2d.  Any binaries requiring
17387bded2dbSJung-uk Kim	libcrypto.so.7 or libssl.so.7 must be recompiled.
17397bded2dbSJung-uk Kim
1740ebda5173SAlexander Motin20151020:
1741ebda5173SAlexander Motin	Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
1742ebda5173SAlexander Motin	Kernel modules isp_2400_multi and isp_2500_multi were removed and
1743ebda5173SAlexander Motin	should be replaced with isp_2400 and isp_2500 modules respectively.
1744ebda5173SAlexander Motin
174556585ab5SBryan Drewery20151017:
174656585ab5SBryan Drewery	The build previously allowed using 'make -n' to not recurse into
174756585ab5SBryan Drewery	sub-directories while showing what commands would be executed, and
174856585ab5SBryan Drewery	'make -n -n' to recursively show commands.  Now 'make -n' will recurse
174956585ab5SBryan Drewery	and 'make -N' will not.
175056585ab5SBryan Drewery
1751ff446b05SPeter Wemm20151012:
1752ff446b05SPeter Wemm	If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
1753ff446b05SPeter Wemm	and etcupdate will now use this file. A custom sendmail.cf is now
1754ff446b05SPeter Wemm	updated via this mechanism rather than via installworld.  If you had
1755ff446b05SPeter Wemm	excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
1756ff446b05SPeter Wemm	want to remove the exclusion or change it to "always install".
1757ff446b05SPeter Wemm	/etc/mail/sendmail.cf is now managed the same way regardless of
1758ff446b05SPeter Wemm	whether SENDMAIL_MC/SENDMAIL_CF is used.  If you are not using
1759ff446b05SPeter Wemm	SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
1760ff446b05SPeter Wemm
17614a3760baSAlexander Motin20151011:
17624a3760baSAlexander Motin	Compatibility shims for legacy ATA device names have been removed.
17634a3760baSAlexander Motin	It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
17644a3760baSAlexander Motin	and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*

17725882166bSEd Maste20150924:
177305117b57SEd Maste	Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
177405117b57SEd Maste	and renamed from .symbols to .debug. This reduces the size requirements
177505117b57SEd Maste	on the boot partition or file system and provides consistency with
177605117b57SEd Maste	userland debug files.
177705117b57SEd Maste
177805117b57SEd Maste	When using the supported kernel installation method the
177905117b57SEd Maste	/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
178005117b57SEd Maste	as is done with /boot/kernel.
178105117b57SEd Maste
178205117b57SEd Maste	Developers wishing to maintain the historical behavior of installing
178305117b57SEd Maste	debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).

178564b3b4d6SKristof Provost20150827:
17868ed69220SGleb Smirnoff	The wireless drivers had undergone changes that remove the 'parent
17878ed69220SGleb Smirnoff	interface' from the ifconfig -l output. The rc.d network scripts
17888ed69220SGleb Smirnoff	used to check presence of a parent interface in the list, so old
17898ed69220SGleb Smirnoff	scripts would fail to start wireless networking. Thus, etcupdate(3)
17908ed69220SGleb Smirnoff	or mergemaster(8) run is required after kernel update, to update your
17918ed69220SGleb Smirnoff	rc.d scripts in /etc.
17928ed69220SGleb Smirnoff
17938ed69220SGleb Smirnoff20150827:
179464b3b4d6SKristof Provost	pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
179564b3b4d6SKristof Provost	These configurations are now automatically interpreted as

1798646041a8SMark Murray20150817:
1799646041a8SMark Murray	Kernel-loadable modules for the random(4) device are back. To use
1800646041a8SMark Murray	them, the kernel must have
1801646041a8SMark Murray
1802646041a8SMark Murray	device	random
1803646041a8SMark Murray	options	RANDOM_LOADABLE
1804646041a8SMark Murray
1805646041a8SMark Murray	kldload(8) can then be used to load random_fortuna.ko
1806646041a8SMark Murray	or random_yarrow.ko. Please note that due to the indirect
1807646041a8SMark Murray	function calls that the loadable modules need to provide,
1808646041a8SMark Murray	the build-in variants will be slightly more efficient.
1809646041a8SMark Murray
1810646041a8SMark Murray	The random(4) kernel option RANDOM_DUMMY has been retired due to
1811646041a8SMark Murray	unpopularity. It was not all that useful anyway.
1812646041a8SMark Murray
18131bc28ffcSEd Maste20150813:
18141bc28ffcSEd Maste	The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
18151bc28ffcSEd Maste	Control over building the ELF Tool Chain tools is now provided by
18161bc28ffcSEd Maste	the WITHOUT_TOOLCHAIN knob.

1818e7dbaf58SIan Lepore20150810:
1819e7dbaf58SIan Lepore	The polarity of Pulse Per Second (PPS) capture events with the
1820e7dbaf58SIan Lepore	uart(4) driver has been corrected.  Prior to this change the PPS
1821e7dbaf58SIan Lepore	"assert" event corresponded to the trailing edge of a positive PPS
1822e7dbaf58SIan Lepore	pulse and the "clear" event was the leading edge of the next pulse.
1823e7dbaf58SIan Lepore
1824e7dbaf58SIan Lepore	As the width of a PPS pulse in a typical GPS receiver is on the
1825e7dbaf58SIan Lepore	order of 1 millisecond, most users will not notice any significant
1826e7dbaf58SIan Lepore	difference with this change.
1827e7dbaf58SIan Lepore
1828e7dbaf58SIan Lepore	Anyone who has compensated for the historical polarity reversal by
1829e7dbaf58SIan Lepore	configuring a negative offset equal to the pulse width will need to
1830e7dbaf58SIan Lepore	remove that workaround.

18409322ac3fSAllan Jude20150806:
18419322ac3fSAllan Jude	The menu.rc and loader.rc files will now be replaced during
18429322ac3fSAllan Jude	upgrades. Please migrate local changes to menu.rc.local and

1845f97aa232SEd Maste20150805:
1846f97aa232SEd Maste	GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
1847f97aa232SEd Maste	strings and strip have been removed. The src.conf(5) knob
1848f97aa232SEd Maste	WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.

18501635369eSSteven Hartland20150728:
185168d5f492SSteven Hartland	As ZFS requires more kernel stack pages than is the default on some
18521635369eSSteven Hartland	architectures e.g. i386, it now warns if KSTACK_PAGES is less than
18531635369eSSteven Hartland	ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
18541635369eSSteven Hartland
18551635369eSSteven Hartland	Please consider using 'options KSTACK_PAGES=X' where X is greater
18561635369eSSteven Hartland	than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.

1858ab1f4a42SGregory Neil Shapiro20150706:
1859ab1f4a42SGregory Neil Shapiro	sendmail has been updated to 8.15.2.  Starting with FreeBSD 11.0
1860ab1f4a42SGregory Neil Shapiro	and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
1861ab1f4a42SGregory Neil Shapiro	default, i.e., they will not contain "::".  For example, instead
1862ab1f4a42SGregory Neil Shapiro	of ::1, it will be 0:0:0:0:0:0:0:1.  This permits a zero subnet
1863ab1f4a42SGregory Neil Shapiro	to have a more specific match, such as different map entries for
1864ab1f4a42SGregory Neil Shapiro	IPv6:0:0 vs IPv6:0.  This change requires that configuration
1865ab1f4a42SGregory Neil Shapiro	data (including maps, files, classes, custom ruleset, etc.) must
1866ab1f4a42SGregory Neil Shapiro	use the same format, so make certain such configuration data is
1867ab1f4a42SGregory Neil Shapiro	upgrading.  As a very simple check search for patterns like
1868ab1f4a42SGregory Neil Shapiro	'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'.  To return to the old
1869ab1f4a42SGregory Neil Shapiro	behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
1870ab1f4a42SGregory Neil Shapiro	the cf option UseCompressedIPv6Addresses.

1872d1b06863SMark Murray20150630:
1873d1b06863SMark Murray	The default kernel entropy-processing algorithm is now
1874d1b06863SMark Murray	Fortuna, replacing Yarrow.
18756f78e390SSimon J. Gerraty
1876d1b06863SMark Murray	Assuming you have 'device random' in your kernel config
1877d1b06863SMark Murray	file, the configurations allow a kernel option to override
1878d1b06863SMark Murray	this default. You may choose *ONE* of:
18796f78e390SSimon J. Gerraty
1880d1b06863SMark Murray	options	RANDOM_YARROW	# Legacy /dev/random algorithm.
1881d1b06863SMark Murray	options	RANDOM_DUMMY	# Blocking-only driver.
18826f78e390SSimon J. Gerraty
1883d1b06863SMark Murray	If you have neither, you get Fortuna.  For most people,
1884d1b06863SMark Murray	read no further, Fortuna will give a /dev/random that works
1885d1b06863SMark Murray	like it always used to, and the difference will be irrelevant.
18866f78e390SSimon J. Gerraty
1887d1b06863SMark Murray	If you remove 'device random', you get *NO* kernel-processed
188802dcb6e0SEitan Adler	entropy at all. This may be acceptable to folks building
1889d1b06863SMark Murray	embedded systems, but has complications. Carry on reading,
1890d1b06863SMark Murray	and it is assumed you know what you need.
1891d1b06863SMark Murray
1892d1b06863SMark Murray	*PLEASE* read random(4) and random(9) if you are in the
189302dcb6e0SEitan Adler	habit of tweaking kernel configs, and/or if you are a member
1894d1b06863SMark Murray	of the embedded community, wanting specific and not-usual
1895d1b06863SMark Murray	behaviour from your security subsystems.

1897d1b06863SMark Murray	NOTE!! If you use RANDOM_DUMMY and/or have no 'device
1898d1b06863SMark Murray	random', you will NOT have a functioning /dev/random, and
1899d1b06863SMark Murray	many cryptographic features will not work, including SSH.
1900d1b06863SMark Murray	You may also find strange behaviour from the random(3) set
1901d1b06863SMark Murray	of library functions, in particular sranddev(3), srandomdev(3)
1902d1b06863SMark Murray	and arc4random(3). The reason for this is that the KERN_ARND
1903d1b06863SMark Murray	sysctl only returns entropy if it thinks it has some to
1904d1b06863SMark Murray	share, and with RANDOM_DUMMY or no 'device random' this
1905d1b06863SMark Murray	will never happen.

2055143c11b4SDimitry Andric20141231:
2056143c11b4SDimitry Andric	Clang, llvm and lldb have been upgraded to 3.5.0 release.
2057143c11b4SDimitry Andric
20580ac2c3d1SDimitry Andric	As of this release, a prerequisite for building clang, llvm and lldb is
20590ac2c3d1SDimitry Andric	a C++11 capable compiler and C++11 standard library.  This means that to
2060143c11b4SDimitry Andric	be able to successfully build the cross-tools stage of buildworld, with
2061143c11b4SDimitry Andric	clang as the bootstrap compiler, your system compiler or cross compiler
2062143c11b4SDimitry Andric	should either be clang 3.3 or later, or gcc 4.8 or later, and your
2063143c11b4SDimitry Andric	system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
2064143c11b4SDimitry Andric	later.
2065143c11b4SDimitry Andric
20660ac2c3d1SDimitry Andric	On any standard FreeBSD 10.x or 11.x installation, where clang and
20670ac2c3d1SDimitry Andric	libc++ are on by default (that is, on x86 or arm), this should work out
20680ac2c3d1SDimitry Andric	of the box.
2069143c11b4SDimitry Andric
2070143c11b4SDimitry Andric	On 9.x installations where clang is enabled by default, e.g. on x86 and
2071143c11b4SDimitry Andric	powerpc, libc++ will not be enabled by default, so libc++ should be
2072143c11b4SDimitry Andric	built (with clang) and installed first.  If both clang and libc++ are
2073143c11b4SDimitry Andric	missing, build clang first, then use it to build libc++.
2074143c11b4SDimitry Andric
2075143c11b4SDimitry Andric	On 8.x and earlier installations, upgrade to 9.x first, and then follow
2076143c11b4SDimitry Andric	the instructions for 9.x above.
2077143c11b4SDimitry Andric
20780ac2c3d1SDimitry Andric	Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
20790ac2c3d1SDimitry Andric	default, and do not build clang.
20800ac2c3d1SDimitry Andric
20810ac2c3d1SDimitry Andric	Many embedded systems are resource constrained, and will not be able to
20820ac2c3d1SDimitry Andric	build clang in a reasonable time, or in some cases at all.  In those
20830ac2c3d1SDimitry Andric	cases, cross building bootable systems on amd64 is a workaround.
20840ac2c3d1SDimitry Andric
2085143c11b4SDimitry Andric	This new version of clang introduces a number of new warnings, of which
2086143c11b4SDimitry Andric	the following are most likely to appear:
2087143c11b4SDimitry Andric
2088143c11b4SDimitry Andric	-Wabsolute-value
2089143c11b4SDimitry Andric
2090143c11b4SDimitry Andric	This warns in two cases, for both C and C++:
2091143c11b4SDimitry Andric	* When the code is trying to take the absolute value of an unsigned
2092143c11b4SDimitry Andric	  quantity, which is effectively a no-op, and almost never what was
2093143c11b4SDimitry Andric	  intended.  The code should be fixed, if at all possible.  If you are
2094143c11b4SDimitry Andric	  sure that the unsigned quantity can be safely cast to signed, without
2095143c11b4SDimitry Andric	  loss of information or undefined behavior, you can add an explicit
2096143c11b4SDimitry Andric	  cast, or disable the warning.
2097143c11b4SDimitry Andric
2098143c11b4SDimitry Andric	* When the code is trying to take an absolute value, but the called
2099143c11b4SDimitry Andric	  abs() variant is for the wrong type, which can lead to truncation.
2100143c11b4SDimitry Andric	  If you want to disable the warning instead of fixing the code, please
2101143c11b4SDimitry Andric	  make sure that truncation will not occur, or it might lead to unwanted
2102143c11b4SDimitry Andric	  side-effects.
2103143c11b4SDimitry Andric
2104143c11b4SDimitry Andric	-Wtautological-undefined-compare and
2105143c11b4SDimitry Andric	-Wundefined-bool-conversion
2106143c11b4SDimitry Andric
2107143c11b4SDimitry Andric	These warn when C++ code is trying to compare 'this' against NULL, while
2108143c11b4SDimitry Andric	'this' should never be NULL in well-defined C++ code.  However, there is
2109143c11b4SDimitry Andric	some legacy (pre C++11) code out there, which actively abuses this
2110143c11b4SDimitry Andric	feature, which was less strictly defined in previous C++ versions.
2111143c11b4SDimitry Andric
2112143c11b4SDimitry Andric	Squid and openjdk do this, for example.  The warning can be turned off
2113143c11b4SDimitry Andric	for C++98 and earlier, but compiling the code in C++11 mode might result
2114143c11b4SDimitry Andric	in unexpected behavior; for example, the parts of the program that are
2115143c11b4SDimitry Andric	unreachable could be optimized away.

2178232490c6SNathan Whitehorn	The ofwfb driver, used to provide a graphics console on PowerPC when
217974342541SChristian Brueffer	using vt(4), no longer allows mmap() of all physical memory. This
2180232490c6SNathan Whitehorn	will prevent Xorg on PowerPC with some ATI graphics cards from
2181232490c6SNathan Whitehorn	initializing properly unless x11-servers/xorg-server is updated to

221518aa7fccSRick Macklem	Commit r268115 has added NFSv4.1 server support, merged from
221618aa7fccSRick Macklem	projects/nfsv4.1-server.  Since this includes changes to the
221718aa7fccSRick Macklem	internal interfaces between the NFS related modules, a full
221818aa7fccSRick Macklem	build of the kernel and modules will be necessary.
221918aa7fccSRick Macklem	__FreeBSD_version has been bumped.

222738b72f8cSAlexander Motin	Maximal length of the serial number in CTL was increased from 16 to
222838b72f8cSAlexander Motin	64 chars, that breaks ABI.  All CTL-related tools, such as ctladm

2231727a7ce8SJulio Merino20140606:
2232727a7ce8SJulio Merino	The libatf-c and libatf-c++ major versions were downgraded to 0 and
2233727a7ce8SJulio Merino	1 respectively to match the upstream numbers.  They were out of
2234727a7ce8SJulio Merino	sync because, when they were originally added to FreeBSD, the
2235727a7ce8SJulio Merino	upstream versions were not respected.  These libraries are private
2236727a7ce8SJulio Merino	and not yet built by default, so renumbering them should be a
2237727a7ce8SJulio Merino	non-issue.  However, unclean source trees will yield broken test
2238727a7ce8SJulio Merino	programs once the operator executes "make delete-old-libs" after a
2239727a7ce8SJulio Merino	"make installworld".
2240727a7ce8SJulio Merino
22418c7ec47aSJulio Merino	Additionally, the atf-sh binary was made private by moving it into
22428c7ec47aSJulio Merino	/usr/libexec/.  Already-built shell test programs will keep the
22438c7ec47aSJulio Merino	path to the old binary so they will break after "make delete-old"
22448c7ec47aSJulio Merino	is run.
22458c7ec47aSJulio Merino
2246727a7ce8SJulio Merino	If you are using WITH_TESTS=yes (not the default), wipe the object
2247727a7ce8SJulio Merino	tree and rebuild from scratch to prevent spurious test failures.
22488c7ec47aSJulio Merino	This is only needed once: the misnumbered libraries and misplaced
22498c7ec47aSJulio Merino	binaries have been added to OptionalObsoleteFiles.inc so they will
22508c7ec47aSJulio Merino	be removed during a clean upgrade.

225285d60e68SDimitry Andric20140512:

2255fa114234SWarner Losh20140508:
2256fa114234SWarner Losh	We bogusly installed src.opts.mk in /usr/share/mk. This file should
2257fa114234SWarner Losh	be removed to avoid issues in the future (and has been added to
2258fa114234SWarner Losh	ObsoleteFiles.inc).
2259fa114234SWarner Losh
2260a46954e2SWarner Losh20140505:
2261a46954e2SWarner Losh	/etc/src.conf now affects only builds of the FreeBSD src tree. In the
2262a46954e2SWarner Losh	past, it affected all builds that used the bsd.*.mk files. The old
2263a46954e2SWarner Losh	behavior was a bug, but people may have relied upon it. To get this
2264a46954e2SWarner Losh	behavior back, you can .include /etc/src.conf from /etc/make.conf
2265a46954e2SWarner Losh	(which is still global and isn't changed). This also changes the
2266a46954e2SWarner Losh	behavior of incremental builds inside the tree of individual
226759a24370SWarner Losh	directories. Set MAKESYSPATH to ".../share/mk" to do that.
2268a46954e2SWarner Losh	Although this has survived make universe and some upgrade scenarios,
226955b76981SWarner Losh	other upgrade scenarios may have broken. At least one form of
227055b76981SWarner Losh	temporary breakage was fixed with MAKESYSPATH settings for buildworld
227159a24370SWarner Losh	as well... In cases where MAKESYSPATH isn't working with this
227259a24370SWarner Losh	setting, you'll need to set it to the full path to your tree.
2273a46954e2SWarner Losh
2274bd871f14SWarner Losh	One side effect of all this cleaning up is that bsd.compiler.mk
2275bd871f14SWarner Losh	is no longer implicitly included by bsd.own.mk. If you wish to
2276bd871f14SWarner Losh	use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
2277bd871f14SWarner Losh	as well.

2279461dbce2SEitan Adler20140430:
2280461dbce2SEitan Adler	The lindev device has been removed since /dev/full has been made a

2283e9aba509SEnji Cooper20140424:
2284e9aba509SEnji Cooper	The knob WITHOUT_VI was added to the base system, which controls
2285e9aba509SEnji Cooper	building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
2286e9aba509SEnji Cooper	in order to reorder files share/termcap and didn't build ex(1) as a
2287e9aba509SEnji Cooper	build tool, so building/installing with WITH_VI is highly advised for
2288e9aba509SEnji Cooper	build hosts for older releases.
2289e9aba509SEnji Cooper
2290e9aba509SEnji Cooper	This issue has been fixed in stable/9 and stable/10 in r277022 and
2291e9aba509SEnji Cooper	r276991, respectively.

22932bb08298SWarner Losh20140418:
22942bb08298SWarner Losh	The YES_HESIOD knob has been removed. It has been obsolete for
22952bb08298SWarner Losh	a decade. Please move to using WITH_HESIOD instead or your builds
22962bb08298SWarner Losh	will silently lack HESIOD.

22984c710b67SMarcel Moolenaar20140405:
22994c710b67SMarcel Moolenaar	The uart(4) driver has been changed with respect to its handling
23004c710b67SMarcel Moolenaar	of the low-level console. Previously the uart(4) driver prevented
23014c710b67SMarcel Moolenaar	any process from changing the baudrate or the CLOCAL and HUPCL
23024c710b67SMarcel Moolenaar	control flags. By removing the restrictions, operators can make
23034c710b67SMarcel Moolenaar	changes to the serial console port without having to reboot.
23044c710b67SMarcel Moolenaar	However, when getty(8) is started on the serial device that is
23054c710b67SMarcel Moolenaar	associated with the low-level console, a misconfigured terminal
23064c710b67SMarcel Moolenaar	line in /etc/ttys will now have a real impact.
23074c710b67SMarcel Moolenaar	Before upgrading the kernel, make sure that /etc/ttys has the
23084c710b67SMarcel Moolenaar	serial console device configured as 3wire without baudrate to
2309086036aaSMarcel Moolenaar	preserve the previous behaviour. E.g:
23104c710b67SMarcel Moolenaar	    ttyu0  "/usr/libexec/getty 3wire"  vt100  on  secure

2317a9fd2218SWarner Losh20140226:
2318a9fd2218SWarner Losh	Switched back to the GPL dtc compiler due to updates in the upstream
2319a9fd2218SWarner Losh	dts files not being supported by the BSDL dtc compiler. You will need
2320a9fd2218SWarner Losh	to rebuild your kernel toolchain to pick up the new compiler. Core dumps
2321a9fd2218SWarner Losh	may result while building dtb files during a kernel build if you fail
2322a9fd2218SWarner Losh	to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.

23319f23d19aSDimitry Andric20140212:
23329f23d19aSDimitry Andric	An ABI incompatibility crept into the libc++ 3.4 import in r261283.
23339f23d19aSDimitry Andric	This could cause certain C++ applications using shared libraries built
23349f23d19aSDimitry Andric	against the previous version of libc++ to crash.  The incompatibility
23359f23d19aSDimitry Andric	has now been fixed, but any C++ applications or shared libraries built
23369f23d19aSDimitry Andric	between r261283 and r261801 should be recompiled.

23385e4b8b0dSXin LI20140204:
23395e4b8b0dSXin LI	OpenSSH will now ignore errors caused by kernel lacking of Capsicum
23405e4b8b0dSXin LI	capability mode support.  Please note that enabling the feature in
23415e4b8b0dSXin LI	kernel is still highly recommended.

23435e4b8b0dSXin LI20140131:
23445e4b8b0dSXin LI	OpenSSH is now built with sandbox support, and will use sandbox as

23502e503d34SKai Wang	versions from upstream. Shared library version numbers for
23512e503d34SKai Wang	these two libraries were bumped. Any ports or binaries
23522e503d34SKai Wang	requiring these two libraries should be recompiled.

2355d7efee23SJulio Merino20140110:
2356d7efee23SJulio Merino	If a Makefile in a tests/ directory was auto-generating a Kyuafile
2357d7efee23SJulio Merino	instead of providing an explicit one, this would prevent such
2358d7efee23SJulio Merino	Makefile from providing its own Kyuafile in the future during
2359d7efee23SJulio Merino	NO_CLEAN builds.  This has been fixed in the Makefiles but manual
2360d7efee23SJulio Merino	intervention is needed to clean an objdir if you use NO_CLEAN:

23632773bfa9SBenjamin Kaduk20131213:
23642773bfa9SBenjamin Kaduk	The behavior of gss_pseudo_random() for the krb5 mechanism
23652773bfa9SBenjamin Kaduk	has changed, for applications requesting a longer random string
23662773bfa9SBenjamin Kaduk	than produced by the underlying enctype's pseudo-random() function.
23672773bfa9SBenjamin Kaduk	In particular, the random string produced from a session key of
23682773bfa9SBenjamin Kaduk	enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
23692773bfa9SBenjamin Kaduk	be different at the 17th octet and later, after this change.
23702773bfa9SBenjamin Kaduk	The counter used in the PRF+ construction is now encoded as a

2403a24eff53SWarner Losh	-------------
24045780f3baSWarner Losh	Sometimes, obscure build problems are the result of environment
24055780f3baSWarner Losh	poisoning.  This can happen because the make utility reads its
2406456b5dd8SWarner Losh	environment when searching for values for global variables.  To run
2407456b5dd8SWarner Losh	your build attempts in an "environmental clean room", prefix all make
2408456b5dd8SWarner Losh	commands with 'env -i '.  See the env(1) manual page for more details.
240916ae8351SEd Maste	Occasionally a build failure will occur with "make -j" due to a race
241016ae8351SEd Maste	condition.  If this happens try building again without -j, and please
241116ae8351SEd Maste	report a bug if it happens consistently.

24135ad05815SWarner Losh	When upgrading from one major version to another it is generally best to
24145ad05815SWarner Losh	upgrade to the latest code in the currently installed branch first, then
24155ad05815SWarner Losh	do an upgrade to the new branch. This is the best-tested upgrade path,
24165ad05815SWarner Losh	and has the highest probability of being successful.  Please try this
24175ad05815SWarner Losh	approach if you encounter problems with a major version upgrade.  Since
241844c1484aSJens Schweikhardt	the stable 4.x branch point, one has generally been able to upgrade from

24418fc25799SMartin Matuska	ZFS notes
24428fc25799SMartin Matuska	---------
24438fc25799SMartin Matuska	When upgrading the boot ZFS pool to a new version, always follow
24448fc25799SMartin Matuska	these two steps:
24458fc25799SMartin Matuska
24468fc25799SMartin Matuska	1.) recompile and reinstall the ZFS boot loader and boot block
24478fc25799SMartin Matuska	(this is part of "make buildworld" and "make installworld")
24488fc25799SMartin Matuska
24498fc25799SMartin Matuska	2.) update the ZFS boot block on your boot drive
24508fc25799SMartin Matuska
2451d8e59012SColin Percival	The following example updates the ZFS boot block on the
2452d8e59012SColin Percival	freebsd-boot partition of a GPT partitioned drive ada0:
2453d8e59012SColin Percival	"gpart bootcode -p /boot/gptzfsboot -i $N ada0"
2454d8e59012SColin Percival	The value $N will typically be 1 (if booting from BIOS) or 2 (if
2455d8e59012SColin Percival	booting from EFI).
24568fc25799SMartin Matuska
24578fc25799SMartin Matuska	Non-boot pools do not need these updates.

2460dc0dbf5cSWarner Losh	-----------------
2461ba01eb20SWarner Losh	If you are updating from a prior version of FreeBSD (even one just
24621cf0ef11SDavid E. O'Brien	a few days old), you should follow this procedure.  It is the most
24631cf0ef11SDavid E. O'Brien	failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,

24702e937dd6SAlexander Leidinger	---------------------
24712e937dd6SAlexander Leidinger	If you just want to boot a kernel once (because you are not sure
24722e937dd6SAlexander Leidinger	if it works, or if you want to boot a known bad kernel to provide
24732e937dd6SAlexander Leidinger	debugging information) run

2531ba26da8eSWarner Losh
2532fdb9f54dSWarner Losh	Make sure that you've read the UPDATING file to understand the
2533fdb9f54dSWarner Losh	tweaks to various things you need.  At this point in the life
2534fdb9f54dSWarner Losh	cycle of current, things change often and you are on your own
2535fdb9f54dSWarner Losh	to cope.  The defaults can also change, so please read ALL of
2536fdb9f54dSWarner Losh	the UPDATING entries.
2537ba26da8eSWarner Losh
25381dece4a9SWarner Losh	Also, if you are tracking -current, you must be subscribed to
25391dece4a9SWarner Losh	freebsd-current@freebsd.org.  Make sure that before you update
25401dece4a9SWarner Losh	your sources that you have read and understood all the recent
25411dece4a9SWarner Losh	messages there.  If in doubt, please track -stable which has
25421dece4a9SWarner Losh	much fewer pitfalls.
25431dece4a9SWarner Losh
2544d2799054SWarner Losh	[1] If you have third party modules, such as vmware, you should disable
2545d2799054SWarner Losh	them at this point so they don't crash your system on
2546d2799054SWarner Losh	reboot. Alternatively, you should rebuild all the modules you have in
2547d2799054SWarner Losh	your system and install them as well.  If you are running -current, you
2548d2799054SWarner Losh	should seriously consider placing all sources to all the modules for
2549d2799054SWarner Losh	your system (or symlinks to them) in /usr/local/sys/modules so this
2550d2799054SWarner Losh	happens automatically. If all your modules come from ports, then adding
2551d2799054SWarner Losh	the port origin directories to PORTS_MODULES instead is also automatic
2552d2799054SWarner Losh	and effective, eg:
2553d2799054SWarner Losh	     PORTS_MODULES+=x11/nvidia-driver
2554134d2e86SWarner Losh
2555ee6e1fc3SWarner Losh	[3] From the bootblocks, boot -s, and then do
2556ee6e1fc3SWarner Losh		fsck -p
2557ee6e1fc3SWarner Losh		mount -u /
2558ee6e1fc3SWarner Losh		mount -a
25598ed2d94aSWarner Losh		sh /etc/rc.d/zfs start	# mount zfs filesystem, if needed
25608ed2d94aSWarner Losh		cd src			# full path to source
256147d0d01fSWarner Losh		adjkerntz -i		# if CMOS is wall time
2562d2799054SWarner Losh	Also, when doing a major release upgrade, it is required that you boot
2563d2799054SWarner Losh	into single user mode to do the installworld.
2564ee6e1fc3SWarner Losh
2565a6cd4f9dSWarner Losh	[4] Note: This step is non-optional.  Failure to do this step
2566a6cd4f9dSWarner Losh	can result in a significant reduction in the functionality of the
2567a6cd4f9dSWarner Losh	system.  Attempting to do it by hand is not recommended and those
2568a6cd4f9dSWarner Losh	that pursue this avenue should read this file carefully, as well
2569a6cd4f9dSWarner Losh	as the archives of freebsd-current and freebsd-hackers mailing lists
2570e641c29aSDries Michiels	for potential gotchas.  See etcupdate(8) for more information.
2571a6cd4f9dSWarner Losh
257244c1484aSJens Schweikhardt	[5] Usually this step is a no-op.  However, from time to time
2573835284beSWarner Losh	you may need to do this if you get unknown user in the following
2574e641c29aSDries Michiels	step.
2575835284beSWarner Losh
257694877c06SAlexander Leidinger	[6] This only deletes old files and directories. Old libraries
257794877c06SAlexander Leidinger	can be deleted by "make delete-old-libs", but you have to make
257894877c06SAlexander Leidinger	sure that no program is using those libraries anymore.
257994877c06SAlexander Leidinger
2580ed651a74SWarner Losh	[8] The new kernel must be able to run existing binaries used by an
2581ed651a74SWarner Losh	installworld.  When upgrading across major versions, the new kernel's
2582ed651a74SWarner Losh	configuration must include the correct COMPAT_FREEBSD<n> option for
2583ed651a74SWarner Losh	existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries).  Failure
2584ed651a74SWarner Losh	to do so may leave you with a system that is hard to boot to recover. A
2585ed651a74SWarner Losh	GENERIC kernel will include suitable compatibility options to run
2586ed651a74SWarner Losh	binaries from older branches.  Note that the ability to run binaries
2587ed651a74SWarner Losh	from unsupported branches is not guaranteed.
2588c74fe6afSWarner Losh
2589e5dc5f61SWarner Losh	Make sure that you merge any new devices from GENERIC since the
25908ed2d94aSWarner Losh	last time you updated your kernel config file. Options also
25918ed2d94aSWarner Losh	change over time, so you may need to adjust your custom kernels
25928ed2d94aSWarner Losh	for these as well.
2593e5dc5f61SWarner Losh
2594e5f5a852SEitan Adler	[9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the
2595e5dc5f61SWarner Losh	"?=" instead of the "=" assignment operator, so that buildworld can
2596e5dc5f61SWarner Losh	override the CPUTYPE if it needs to.
2597e5dc5f61SWarner Losh
2598e5dc5f61SWarner Losh	MAKEOBJDIRPREFIX must be defined in an environment variable, and
2599e5dc5f61SWarner Losh	not on the command line, or in /etc/make.conf.  buildworld will
2600e5dc5f61SWarner Losh	warn if it is improperly defined.
