1 Release notes for FreeBSD 14.0.
3 This file describes new user-visible features, changes and updates relevant to
4 users of binary FreeBSD releases. Each entry should describe the change in no
5 more than several sentences and should reference manual pages where an
6 interested user can find more information. Entries should wrap after 80
7 columns. Each entry should begin with one or more commit IDs on one line,
8 specified as a comma separated list and/or range, followed by a colon and a
9 newline. Entries should be separated by a newline.
11 Changes to this file should not be MFCed.
14 The lua-flavored loader(8) will now interpret .lua files that appear in
15 loader_conf_files as lua, and execute them in a sandbox. Existing
16 loader environment variables are available as globals in the sandbox,
17 and any global variable set, if not a table value, will be reflected in
18 the loader environment upon successful execution of the configuration
19 file. Environment variables with names that aren't valid lua names may
20 be accessed as indices of _ENV; e.g., _ENV['net.fibs'].
23 nda is now the default nvme device on all platforms. While nda creates
24 nvd links by default so fstab, etc continues to work, configuration
25 should be updated to the new nda devices.
27 To restore the old behavior, add hw.nvme.use_nvd=1 to loader.conf or
28 `options NVME_USE_NVD=1` to the kernel config. To disable the nvd
29 compatibility aliases, add kern.cam.nda.nvd_compat=0 to loader.conf.
32 Change pw (hence bsdinstall) not to move /home to /usr/home.
33 Previously, when creating the path to home directories, pw
34 would move any path in the root directory under /usr, creating
35 a symlink in root. In particular, the default /home would become
36 /usr/home. Now /home is at the top level by default. /usr/home
37 can be used explicitly.
40 Remove TI code from armv7 GENERIC kernel.
41 This code doesn't cope with newer DTS and hasn't in a long time so
42 support for TI armv7 platform (like BeagleBone and Pandaboard) is now
46 Add a new "fwget" utility.
47 The goal of this utility is to inspect the system for peripherals
48 that needs firmware and install the appropriate packages for them.
49 For now only pci subsystem is supported and only firmwares for Intel
50 and AMD GPUs are known.
53 Add a new "syskrb5" mount option for Kerberized NFSv4.1/4.2 mounts.
54 Without this patch, a Kerberized NFSv4.1/4.2 mount must provide
55 a Kerberos credential for the client at mount time.
56 This patch uses a feature of NFSv4.1/4.2 called SP4_NONE, which
57 allows the state maintenance operations to be performed by any
58 authentication mechanism, so that these operations may be done via
59 AUTH_SYS instead of RPCSEC_GSS (KerberosV). As such, no Kerberos
60 credential is required at mount time.
63 330aa8acdec7,ff2f1f691cdb:
64 Adds support for the SP4_MACH_CRED case for the
65 NFSv4.1/4.2 ExchangeID operation since the Linux
66 NFSv4.1/4.2 client is now using this for Kerberized mounts.
67 This change should only affect Kerberized NFSv4.1/4.2 mounts.
68 The Linux Kerberized NFSv4.1/4.2 mounts currently work without
69 support for this because Linux will fall back to SP4_NONE,
70 but there is no guarantee this fallback will work forever.
72 7344856e3a6d and many others:
73 Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8)
74 and rpc.tlsservd(8) can be run in an appropriately configured
75 vnet prison. The vnet prison must be on its own file system,
76 have the "allow.nfsd" jail parameter set on it and enforce_statfs
77 cannot be set to "0". Use of UDP and pNFS server configurations
78 are not permitted. (ie. The nfsd command line options "-u", "-p"
79 and "-m" are not supported.)
80 See jail(8), nfsd(8) and mountd(8).

83 sendmail has been updated to the latest upstream version (8.17.1).
85 4a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818:
86 The growfs(7) script can now add a swap partition at the end of
87 the expansion area, and does so by default if there is no existing
91 llvm-objump is now always installed as objdump.
94 mta_start_script along with othermta rc.d script has been retired.
97 The default mail transport agent is now dma(8) replacing sendmail.
100 L3 filtering on if_bridge will do surprising things which aren't
101 fail-safe, so net.link.bridge.pfil_member and
102 net.link.bridge.pfil_bridge now default to zero.
105 A new DTrace provider, kinst, is introduced and documented in
106 dtrace_kinst(4). The provider allows kernel instructions to be traced,
107 similar to the FBT (function boundary tracing) provider except that all
108 instructions may be probed instead of logical entry and return
109 instructions. The provider is currently amd64-only.
114 981ef32230b2,33721eb991d8:
115 These commits make the use of NFSv4.1/4.2 mounts with the "intr"
116 mount option fairly usable, although not 100% correct, so long as
117 the "nolockd" mount option is used as well. See the mount_nfs(8)
118 manual page for more information.
120 b875d4f5ddcb,0685c73cfe88:
121 The NFSv4.1/4.2 client and server will now generate console messages
122 if sessions are broken, suggesting that users check to ensure
123 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
126 makefs(8) has ZFS support; it can create a ZFS pool, backed by a
127 single disk vdev, containing one or more datasets populated from
128 the staging directory.
130 78ee8d1c4cda,f4f56ff43dbd:
131 The in-tree qat(4) driver has been replaced with Intel's QAT driver.
132 The new version provides additional interfaces to the chipset's
133 cryptographic and compression offload functionality.
135 This will have no visible change for most users; however, the new
136 driver does not support Atom C2000 chipsets. To preserve support for
137 those chipsets, the old driver has been renamed to qat_c2xxx and kept
138 in the tree. Users of qat(4) on C2000 hardware will thus need to
139 ensure that qat_c2xxx(4) is loaded instead of qat(4).
141 da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
142 Boottrace is a new kernel-userspace interface for capturing trace
143 events during system boot and shutdown. Event annotations are
146 - The boot and shutdown paths in the kernel
147 - Some key system utilities (init(8), shutdown(8), reboot(8))
148 - rc(8) scripts (via boottrace(8))
150 In contrast to other existing boot-time tracing facilities like TSLOG,
151 Boottrace focuses on the ease of use and is aimed primarily at system
154 It is available in the default GENERIC kernel and can be enabled by
155 toggling a single sysctl(8) variable.
157 See boottrace(4) for more details.
160 Kernel TLS offload now supports receive-side offload of TLS 1.3.
163 if_stf now supports 6rd (RFC5969).
165 c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
166 Add WiFi 6 support to wpa.
168 ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
169 The default bell tone is now 800Hz. It may be set with kbdcontrol
170 again. There's devd integration for people wishing to use their sound
174 net.inet.tcp.nolocaltimewait enabled by default. It prevents
175 creation of timewait entries for TCP connections that were
179 sh(1) is now the default shell for the root user.
182 libncursesw has been split into libtinfow and libncursesw, linker
183 scripts should make it transparent for consumers. pkg-config files
184 are also now installed to ease ports detecting the ncurses setup from
188 LLVM's MemorySanitizer can now be used in amd64 kernels. See the
189 kmsan(9) manual page for more information.
192 LLVM's AddressSanitizer can now be used in amd64 kernels. See the
193 kasan(9) manual page for more information.
195 f39dd6a97844,23f24377b1a9,628bd30ab5a4:
196 One True Awk has been updated to the latest from upstream
197 (20210727). All the FreeBSD patches, but one, have now been
198 either up streamed or discarded. Notable changes include:
199 o Locale is no longer used for ranges
201 o Better compatibility with gawk and mawk
203 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
204 we still allow hex numbers, prefixed with 0x, to be parsed and
205 interpreted as hex numbers while all other awks (including one
206 true awk now) interpret them as 0 in line with awk's historic
209 A second change, less likely to be noticed, is the historic wart
210 if -Ft meaning to use hard tab characters as the field separator
211 is deprecated and will likely be removed in FreeBSD 14.
214 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
215 that can be used to increase the maximum I/O size for the NFS
216 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
217 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
218 via the vfs.maxbcachebuf tunable and the Linux NFS client
219 can also do 1Mbyte I/O.
220 kern.ipc.maxsockbuf will need to be increased. A console
221 message will suggest a setting for it.
224 gconcat(8) has added support for appending devices to the device
225 not present at creation time.
228 Remove support for asymmetric cryptographic operations from
229 the kernel open cryptographic framework (OCF).
232 The NFSv4 client now uses the highest minor version of NFSv4
233 supported by the NFSv4 server by default instead of minor version 0,
235 The "minorversion" mount option may be used to override this default.
