1 Release notes for FreeBSD 13.0.
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 Change the default minor version used for an NFSv4 mount
15 to the highest minor version supported by the NFSv4 server.
16 This default can be overridden by using the "minorversion"
19 2c76eebca71b, 59f6f5e23c1a:
20 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
21 support for NFS-over-TLS as described in the Internet Draft titled
22 "Towards Remote Procedure Call Encryption By Default".
23 These daemons are only built when WITH_OPENSSL_KTLS is specified
24 and are only tested on amd64 at this time.
25 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
26 optional verification of machine identity via X.509 certificates.
29 Add AES-GCM support to armv8crypto(4) providing accelerated
30 support for KTLS, IPsec, and other crypto API consumers.
33 The aesni(4) and armv8crypto(4) devices are now included in
34 GENERIC on amd64, i386, and arm64.
37 Add support for enforcing W^X mapping policy for user
38 processes. The policy is not enforced by default but can be
39 enabled by setting the kern.elf32.allow_wx and
40 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
41 exempted from the policy by elfctl(1) via the wxneeded
45 Add AES-XTS support to armv8crypto(4) providing accelerated
46 software support for the default GELI cipher on arm64 systems.
49 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
53 The fusefs(5) protocol has been updated to 7.28. Support for
54 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
57 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
58 gdb package or devel/gdb port.
61 The hme(4) driver was removed.
64 Fixes the case where gssd will not startup because /usr is a separate
65 local file system that is not yet mounted. It does not fix the case
66 where /usr is a separately mounted remote file system (such as NFS).
67 This latter case can be fixed by adding mountcritremote to the
68 REQUIRED line. Unfortunately doing so implies that all Kerberized
69 NFS mounts in /etc/fstab will need the "late" mount option.
70 This was not done, since the requirement for "late" would introduce
74 This commit added a new startup scripts variable called
75 nfsv4_server_only which uses the -R option on mountd added by r367026.
76 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
77 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
78 does not need to be running. Useful for sites which consider rpcbind a
82 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
83 was split out from amd64 DMAR support and is now generic, i.e., it can
84 be used by all architectures.
87 A series of commits ending with r364896 added NFS over TLS
88 to the kernel. This is believed to be compatible with
89 the Internet Draft titled "Towards Remote Procedure Call Encryption
90 By Default" (expected to soon become an RFC).
91 The mount_nfs(8) and exports(5) man pages describe the mount and
92 export option(s) related to NFS over TLS.
93 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
94 { server } must be running on a kernel built with "options KERN_TLS"
95 on an architecture where PMAP_HAS_DMAP != 0.
98 Changes to one obscure devd event generated on resume need to
99 be documented. The old form will still be generated in 13, but not
103 Applications using regex(3), e.g. sed/grep, will no longer accept
104 redundant escapes for most ordinary characters.
107 SCTP support has been removed from GENERIC kernel configurations.
108 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
111 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
114 The safexcel(4) crypto offload driver has been added.
117 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
120 A new implementation of bc and dc has been imported. It offers
121 better standards compliance, performance, localization and comes
122 with extensive test cases that are optionally installed.
123 Use WITHOUT_GH_BC=yes to build and install the world with the
124 previous version instead of the new one, if required.
127 struct export_args has changed so that the "user" specified for
128 the -maproot and -mapall exports(5) options may be in more than
132 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
133 right thing with them, removing the need for printf magic or obnoxious
134 escaping in many scenarios.
136 r361238, r361798, r361799:
137 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
138 Additionally, read(2) of a directory is now rejected with EISDIR by
139 default and may be re-enabled for non-ZFS filesystems that allow it with
140 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
142 Aliases for grep to default to '-d skip' may be desired if commonly
143 non-recursively grepping a list that includes directories and the
144 possibility of EISDIR errors in stderr is not tolerable. Example
145 aliases, commented out, have been installed in /root/.cshrc and
149 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
150 exec.prepare runs before mounts, so can be used to populate new jails.
151 exec.release runs after unmounts, so can be used to remove ephemeral
154 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
155 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
156 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
157 the kernel open cryptographic framework (OCF).
160 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
161 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
164 Remove support for DES, Triple DES, Blowfish, Cast, and
165 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
166 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
169 Remove support for Triple DES, Blowfish, and MD5 HMAC from
173 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
180 init(8), service(8), and cron(8) will now adopt user/class environment
181 variables (excluding PATH, by default, which will be overwritten) by
182 default. Notably, environment variables for all cron jobs and rc
183 services can now be set via login.conf(5).
186 sparc64 has been removed from FreeBSD.
189 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
190 (RFC-8276) to the NFS client and server.
191 NFSv4.2 is comprised of several optional features that can be supported
192 in addition to NFSv4.1. This patch adds the following optional features:
193 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
195 - intra server file range copying via the copy_file_range(2) syscall
196 --> Avoiding data tranfer over the wire to/from the NFS client.
197 - lseek(SEEK_DATA/SEEK_HOLE)
198 - Extended attribute syscalls for "user" namespace attributes as defined
201 For the client, NFSv4.2 is only used if the mount command line option
202 minorversion=2 is specified.
203 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
204 and vfs.nfsd.server_max_minorversion4 have been added that allow
205 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
207 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
211 armv5 support has been removed from FreeBSD.
214 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
217 sqlite3 is updated to sqlite3-3.30.1.
220 cron(8) now supports the -n (suppress mail on succesful run) and -q
221 (suppress logging of command execution) options in the crontab format.
222 See the crontab(5) manpage for details.
225 ntpd is no longer by default locked in memory. rlimit memlock 32
226 or rlimit memlock 0 can be used to restore this behaviour.
229 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
230 environment variables set by a user via ${name}_env were ignored
231 if the service defined a custom *_cmd variable to control the behavior
232 of the run_rc_command function, e.g., start_cmd, instead of relying on
233 the variables like command and command_args,
235 r351770,r352920,r352922,r352923:
236 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
237 and iflag=fullblock flags, compatible with illumos and GNU.
240 Add kernel-side support for in-kernel Transport Layer Security
241 (KTLS). KTLS permits using sendfile(2) over sockets using
245 WPA is updated from 2.8 to 2.9.
248 Add probes for lockmgr(9) to the lockstat DTrace provider, add
249 corresponding lockstat(1) events, and document the new probes in
253 Intel RST is a new 'feature' that remaps NVMe devices from
254 their normal location to part of the AHCI bar space. This
255 will eliminate the need to set the BIOS SATA setting from RST
256 to AHCI causing the nvme drive to be erased before FreeBSD
257 will see the nvme drive. FreeBSD will now be able to see the
258 nvme drive now in the default config.
261 Add a vop_stdioctl() call, so that file systems that do not support
262 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
263 The algorithm appears to be compatible with the POSIX draft and
264 the implementation in Linux for the case of a file system that
265 does not support holes. Prior to this patch, lseek(2) would reply
266 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
267 file systems that do not support holes.
268 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
269 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
272 The fuse driver has been renamed to fusefs(5) and been substantially
273 rewritten. The new driver includes many bug fixes and performance
274 enhancements, as well as the following user-visible features:
275 * Optional kernel-side permissions checks (-o default_permissions)
276 * mknod(2), socket(2), and pipe(2) support
277 * server side locking with fcntl(2)
278 * FUSE operations are now interruptible when mounted with -o intr
279 * server side handling of UTIME_NOW during utimensat(2)
280 * mount options may be updated with "mount -u"
281 * fusefs file system may now be exported over NFS
282 * RLIMIT_FSIZE support
283 * support for fuse file systems using protocols as old as 7.4
285 FUSE file system developers should also take note of the following new
287 * The protocol level has been raised from 7.8 to 7.23
288 * kqueue support on /dev/fuse
289 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
292 gnop(8) can now configure a delay to be applied to read and write
293 request delays. See the -d, -q and -x parameters.
296 Adds a Linux compatible copy_file_range(2) syscall.
299 libcap_random(3) has been removed. Applications can use native
300 APIs to get random data in capability mode.
303 Add support for using unmapped mbufs with sendfile(2).
306 nand(4) and related components have been removed.
309 The UEFI loader now supports HTTP boot.
312 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
313 guests to play to and record audio data from the host.
316 swapon(8) can now erase a swap device immediately before enabling it,
317 similar to newfs(8)'s -E option. This behaviour can be specified by
318 adding -E to swapon(8)'s command-line parameters, or by adding the
319 "trimonce" option to a swap device's /etc/fstab entry.
322 The following network drivers have been removed: bm(4), cs(4), de(4),
323 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
327 Wired page accounting has been split into kernel wirings and user
328 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
329 the global limit, which is renamed to vm.max_user_wired. bhyve -S
330 allocates user-wired memory and is now subject to that limit.
