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 Add support for the HiFive Unmatched RISC-V board.
17 Add a sysctl called vfs.nfsd.srvmaxio that can be used to
18 increase the NFS server's maximum I/O size from 128Kbytes
19 to any power of 2 up to 1Mbyte. It can only be set when
20 the nfsd threads are not running and will normally require
21 an increase in kern.ipc.maxsockbuf to at least the value
22 recommended by the console log message generated when
23 setting vfs.nfsd.srvmaxio is first attempted.
26 Add a new NFSv4.1/4.2 mount option "nconnect" that can
27 be used to specify the number of TCP connections that
28 will be used for the mount, up to a maximum of 16.
29 The first (default) TCP connection will be used for
30 all RPCs that consist of small RPC messages.
31 The RPCs that can consist of large RPC messages
32 (Read/Readdir/ReaddirPlus/Write) will be sent on the
33 additional TCP connections in a round robin fashion.
34 If either the NFS client or NFS server have multiple
35 network interfaces aggregated together or a network
36 interface that uses multiple queues, this can increase
37 NFS performance for the mount.
40 One True Awk has been updated to the latest from upstream
41 (20210215). All the FreeBSD patches, but one, have now been
42 either up streamed or discarded. Notable changes include:
43 o Locale is no longer used for ranges
45 o Better compatibility with gawk and mawk
47 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
48 we still allow hex numbers, prefixed with 0x, to be parsed and
49 interpreted as hex numbers while all other awks (including one
50 true awk now) interpret them as 0 in line with awk's historic
54 Change the default minor version used for an NFSv4 mount
55 to the highest minor version supported by the NFSv4 server.
56 This default can be overridden by using the "minorversion"
59 2c76eebca71b, 59f6f5e23c1a:
60 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
61 support for NFS-over-TLS as described in the Internet Draft titled
62 "Towards Remote Procedure Call Encryption By Default".
63 These daemons are only built when WITH_OPENSSL_KTLS is specified
64 and are only tested on amd64 at this time.
65 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
66 optional verification of machine identity via X.509 certificates.
69 Add AES-GCM support to armv8crypto(4) providing accelerated
70 support for KTLS, IPsec, and other crypto API consumers.
73 The aesni(4) and armv8crypto(4) devices are now included in
74 GENERIC on amd64, i386, and arm64.
77 Add support for enforcing W^X mapping policy for user
78 processes. The policy is not enforced by default but can be
79 enabled by setting the kern.elf32.allow_wx and
80 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
81 exempted from the policy by elfctl(1) via the wxneeded
85 Add AES-XTS support to armv8crypto(4) providing accelerated
86 software support for the default GELI cipher on arm64 systems.
89 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
93 The fusefs(5) protocol has been updated to 7.28. Support for
94 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
97 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
98 gdb package or devel/gdb port.
101 The hme(4) driver was removed.
104 Fixes the case where gssd will not startup because /usr is a separate
105 local file system that is not yet mounted. It does not fix the case
106 where /usr is a separately mounted remote file system (such as NFS).
107 This latter case can be fixed by adding mountcritremote to the
108 REQUIRED line. Unfortunately doing so implies that all Kerberized
109 NFS mounts in /etc/fstab will need the "late" mount option.
110 This was not done, since the requirement for "late" would introduce
114 This commit added a new startup scripts variable called
115 nfsv4_server_only which uses the -R option on mountd added by r367026.
116 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
117 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
118 does not need to be running. Useful for sites which consider rpcbind a
122 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
123 was split out from amd64 DMAR support and is now generic, i.e., it can
124 be used by all architectures.
127 A series of commits ending with r364896 added NFS over TLS
128 to the kernel. This is believed to be compatible with
129 the Internet Draft titled "Towards Remote Procedure Call Encryption
130 By Default" (expected to soon become an RFC).
131 The mount_nfs(8) and exports(5) man pages describe the mount and
132 export option(s) related to NFS over TLS.
133 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
134 { server } must be running on a kernel built with "options KERN_TLS"
135 on an architecture where PMAP_HAS_DMAP != 0.
138 Changes to one obscure devd event generated on resume need to
139 be documented. The old form will still be generated in 13, but not
143 Applications using regex(3), e.g. sed/grep, will no longer accept
144 redundant escapes for most ordinary characters.
147 SCTP support has been removed from GENERIC kernel configurations.
148 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
151 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
154 The safexcel(4) crypto offload driver has been added.
157 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
160 A new implementation of bc and dc has been imported. It offers
161 better standards compliance, performance, localization and comes
162 with extensive test cases that are optionally installed.
163 Use WITHOUT_GH_BC=yes to build and install the world with the
164 previous version instead of the new one, if required.
167 struct export_args has changed so that the "user" specified for
168 the -maproot and -mapall exports(5) options may be in more than
172 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
173 right thing with them, removing the need for printf magic or obnoxious
174 escaping in many scenarios.
176 r361238, r361798, r361799:
177 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
178 Additionally, read(2) of a directory is now rejected with EISDIR by
179 default and may be re-enabled for non-ZFS filesystems that allow it with
180 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
182 Aliases for grep to default to '-d skip' may be desired if commonly
183 non-recursively grepping a list that includes directories and the
184 possibility of EISDIR errors in stderr is not tolerable. Example
185 aliases, commented out, have been installed in /root/.cshrc and
189 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
190 exec.prepare runs before mounts, so can be used to populate new jails.
191 exec.release runs after unmounts, so can be used to remove ephemeral
194 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
195 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
196 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
197 the kernel open cryptographic framework (OCF).
200 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
201 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
204 Remove support for DES, Triple DES, Blowfish, Cast, and
205 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
206 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
209 Remove support for Triple DES, Blowfish, and MD5 HMAC from
213 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
220 init(8), service(8), and cron(8) will now adopt user/class environment
221 variables (excluding PATH, by default, which will be overwritten) by
222 default. Notably, environment variables for all cron jobs and rc
223 services can now be set via login.conf(5).
226 sparc64 has been removed from FreeBSD.
229 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
230 (RFC-8276) to the NFS client and server.
231 NFSv4.2 is comprised of several optional features that can be supported
232 in addition to NFSv4.1. This patch adds the following optional features:
233 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
235 - intra server file range copying via the copy_file_range(2) syscall
236 --> Avoiding data tranfer over the wire to/from the NFS client.
237 - lseek(SEEK_DATA/SEEK_HOLE)
238 - Extended attribute syscalls for "user" namespace attributes as defined
241 For the client, NFSv4.2 is only used if the mount command line option
242 minorversion=2 is specified.
243 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
244 and vfs.nfsd.server_max_minorversion4 have been added that allow
245 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
247 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
251 armv5 support has been removed from FreeBSD.
254 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
257 sqlite3 is updated to sqlite3-3.30.1.
260 cron(8) now supports the -n (suppress mail on succesful run) and -q
261 (suppress logging of command execution) options in the crontab format.
262 See the crontab(5) manpage for details.
265 ntpd is no longer by default locked in memory. rlimit memlock 32
266 or rlimit memlock 0 can be used to restore this behaviour.
269 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
270 environment variables set by a user via ${name}_env were ignored
271 if the service defined a custom *_cmd variable to control the behavior
272 of the run_rc_command function, e.g., start_cmd, instead of relying on
273 the variables like command and command_args,
275 r351770,r352920,r352922,r352923:
276 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
277 and iflag=fullblock flags, compatible with illumos and GNU.
280 Add kernel-side support for in-kernel Transport Layer Security
281 (KTLS). KTLS permits using sendfile(2) over sockets using
285 WPA is updated from 2.8 to 2.9.
288 Add probes for lockmgr(9) to the lockstat DTrace provider, add
289 corresponding lockstat(1) events, and document the new probes in
293 Intel RST is a new 'feature' that remaps NVMe devices from
294 their normal location to part of the AHCI bar space. This
295 will eliminate the need to set the BIOS SATA setting from RST
296 to AHCI causing the nvme drive to be erased before FreeBSD
297 will see the nvme drive. FreeBSD will now be able to see the
298 nvme drive now in the default config.
301 Add a vop_stdioctl() call, so that file systems that do not support
302 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
303 The algorithm appears to be compatible with the POSIX draft and
304 the implementation in Linux for the case of a file system that
305 does not support holes. Prior to this patch, lseek(2) would reply
306 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
307 file systems that do not support holes.
308 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
309 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
312 The fuse driver has been renamed to fusefs(5) and been substantially
313 rewritten. The new driver includes many bug fixes and performance
314 enhancements, as well as the following user-visible features:
315 * Optional kernel-side permissions checks (-o default_permissions)
316 * mknod(2), socket(2), and pipe(2) support
317 * server side locking with fcntl(2)
318 * FUSE operations are now interruptible when mounted with -o intr
319 * server side handling of UTIME_NOW during utimensat(2)
320 * mount options may be updated with "mount -u"
321 * fusefs file system may now be exported over NFS
322 * RLIMIT_FSIZE support
323 * support for fuse file systems using protocols as old as 7.4
325 FUSE file system developers should also take note of the following new
327 * The protocol level has been raised from 7.8 to 7.23
328 * kqueue support on /dev/fuse
329 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
332 gnop(8) can now configure a delay to be applied to read and write
333 request delays. See the -d, -q and -x parameters.
336 Adds a Linux compatible copy_file_range(2) syscall.
339 libcap_random(3) has been removed. Applications can use native
340 APIs to get random data in capability mode.
343 Add support for using unmapped mbufs with sendfile(2).
346 nand(4) and related components have been removed.
349 The UEFI loader now supports HTTP boot.
352 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
353 guests to play to and record audio data from the host.
356 swapon(8) can now erase a swap device immediately before enabling it,
357 similar to newfs(8)'s -E option. This behaviour can be specified by
358 adding -E to swapon(8)'s command-line parameters, or by adding the
359 "trimonce" option to a swap device's /etc/fstab entry.
362 The following network drivers have been removed: bm(4), cs(4), de(4),
363 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
367 Wired page accounting has been split into kernel wirings and user
368 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
369 the global limit, which is renamed to vm.max_user_wired. bhyve -S
370 allocates user-wired memory and is now subject to that limit.
