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 Kernel TLS offload now supports receive-side offload of TLS 1.3.
17 Change handling of the lowest address on an IPv4 (sub)net so that
18 packets are not sent as a broadcast unless this has been set as the
19 broadcast address. This makes the lowest address usable for a host.
20 The old behavior can be restored with the net.inet.ip.broadcast_lowest
21 sysctl. For more information, see
22 https://datatracker.ietf.org/doc/draft-schoen-intarea-lowest-address/.
24 33ff39796ffe,8719e8a951b7:
25 A new rc(8) service script zfskeys allows for automatic decryption
26 of ZFS datasets encrypted with ZFS native encryption during boot.
27 See the rc.conf(5) manual page for more information.
29 b7a2cf0d9102 - eae02d959363:
30 Upgrade bhyve's emulation to version 1.4 of the NVMe specification
32 0a6760a1de32, 3f3676a71266, 580c04df4db6:
36 Add support for the HiFive Unmatched RISC-V board.
39 Add a sysctl called vfs.nfsd.srvmaxio that can be used to
40 increase the NFS server's maximum I/O size from 128Kbytes
41 to any power of 2 up to 1Mbyte. It can only be set when
42 the nfsd threads are not running and will normally require
43 an increase in kern.ipc.maxsockbuf to at least the value
44 recommended by the console log message generated when
45 setting vfs.nfsd.srvmaxio is first attempted.
48 Add a new NFSv4.1/4.2 mount option "nconnect" that can
49 be used to specify the number of TCP connections that
50 will be used for the mount, up to a maximum of 16.
51 The first (default) TCP connection will be used for
52 all RPCs that consist of small RPC messages.
53 The RPCs that can consist of large RPC messages
54 (Read/Readdir/ReaddirPlus/Write) will be sent on the
55 additional TCP connections in a round robin fashion.
56 If either the NFS client or NFS server have multiple
57 network interfaces aggregated together or a network
58 interface that uses multiple queues, this can increase
59 NFS performance for the mount.
62 One True Awk has been updated to the latest from upstream
63 (20210215). All the FreeBSD patches, but one, have now been
64 either up streamed or discarded. Notable changes include:
65 o Locale is no longer used for ranges
67 o Better compatibility with gawk and mawk
69 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
70 we still allow hex numbers, prefixed with 0x, to be parsed and
71 interpreted as hex numbers while all other awks (including one
72 true awk now) interpret them as 0 in line with awk's historic
76 Change the default minor version used for an NFSv4 mount
77 to the highest minor version supported by the NFSv4 server.
78 This default can be overridden by using the "minorversion"
81 2c76eebca71b, 59f6f5e23c1a:
82 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
83 support for NFS-over-TLS as described in the Internet Draft titled
84 "Towards Remote Procedure Call Encryption By Default".
85 These daemons are only built when WITH_OPENSSL_KTLS is specified
86 and are only tested on amd64 at this time.
87 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
88 optional verification of machine identity via X.509 certificates.
91 Add AES-GCM support to armv8crypto(4) providing accelerated
92 support for KTLS, IPsec, and other crypto API consumers.
95 The aesni(4) and armv8crypto(4) devices are now included in
96 GENERIC on amd64, i386, and arm64.
99 Add support for enforcing W^X mapping policy for user
100 processes. The policy is not enforced by default but can be
101 enabled by setting the kern.elf32.allow_wx and
102 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
103 exempted from the policy by elfctl(1) via the wxneeded
107 Add AES-XTS support to armv8crypto(4) providing accelerated
108 software support for the default GELI cipher on arm64 systems.
111 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
115 The fusefs(5) protocol has been updated to 7.28. Support for
116 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
119 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
120 gdb package or devel/gdb port.
123 The hme(4) driver was removed.
126 Fixes the case where gssd will not startup because /usr is a separate
127 local file system that is not yet mounted. It does not fix the case
128 where /usr is a separately mounted remote file system (such as NFS).
129 This latter case can be fixed by adding mountcritremote to the
130 REQUIRED line. Unfortunately doing so implies that all Kerberized
131 NFS mounts in /etc/fstab will need the "late" mount option.
132 This was not done, since the requirement for "late" would introduce
136 This commit added a new startup scripts variable called
137 nfsv4_server_only which uses the -R option on mountd added by r367026.
138 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
139 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
140 does not need to be running. Useful for sites which consider rpcbind a
144 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
145 was split out from amd64 DMAR support and is now generic, i.e., it can
146 be used by all architectures.
149 A series of commits ending with r364896 added NFS over TLS
150 to the kernel. This is believed to be compatible with
151 the Internet Draft titled "Towards Remote Procedure Call Encryption
152 By Default" (expected to soon become an RFC).
153 The mount_nfs(8) and exports(5) man pages describe the mount and
154 export option(s) related to NFS over TLS.
155 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
156 { server } must be running on a kernel built with "options KERN_TLS"
157 on an architecture where PMAP_HAS_DMAP != 0.
160 Changes to one obscure devd event generated on resume need to
161 be documented. The old form will still be generated in 13, but not
165 Applications using regex(3), e.g. sed/grep, will no longer accept
166 redundant escapes for most ordinary characters.
169 SCTP support has been removed from GENERIC kernel configurations.
170 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
173 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
176 The safexcel(4) crypto offload driver has been added.
179 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
182 A new implementation of bc and dc has been imported. It offers
183 better standards compliance, performance, localization and comes
184 with extensive test cases that are optionally installed.
185 Use WITHOUT_GH_BC=yes to build and install the world with the
186 previous version instead of the new one, if required.
189 struct export_args has changed so that the "user" specified for
190 the -maproot and -mapall exports(5) options may be in more than
194 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
195 right thing with them, removing the need for printf magic or obnoxious
196 escaping in many scenarios.
198 r361238, r361798, r361799:
199 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
200 Additionally, read(2) of a directory is now rejected with EISDIR by
201 default and may be re-enabled for non-ZFS filesystems that allow it with
202 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
204 Aliases for grep to default to '-d skip' may be desired if commonly
205 non-recursively grepping a list that includes directories and the
206 possibility of EISDIR errors in stderr is not tolerable. Example
207 aliases, commented out, have been installed in /root/.cshrc and
211 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
212 exec.prepare runs before mounts, so can be used to populate new jails.
213 exec.release runs after unmounts, so can be used to remove ephemeral
216 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
217 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
218 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
219 the kernel open cryptographic framework (OCF).
222 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
223 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
226 Remove support for DES, Triple DES, Blowfish, Cast, and
227 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
228 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
231 Remove support for Triple DES, Blowfish, and MD5 HMAC from
235 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
242 init(8), service(8), and cron(8) will now adopt user/class environment
243 variables (excluding PATH, by default, which will be overwritten) by
244 default. Notably, environment variables for all cron jobs and rc
245 services can now be set via login.conf(5).
248 sparc64 has been removed from FreeBSD.
251 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
252 (RFC-8276) to the NFS client and server.
253 NFSv4.2 is comprised of several optional features that can be supported
254 in addition to NFSv4.1. This patch adds the following optional features:
255 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
257 - intra server file range copying via the copy_file_range(2) syscall
258 --> Avoiding data tranfer over the wire to/from the NFS client.
259 - lseek(SEEK_DATA/SEEK_HOLE)
260 - Extended attribute syscalls for "user" namespace attributes as defined
263 For the client, NFSv4.2 is only used if the mount command line option
264 minorversion=2 is specified.
265 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
266 and vfs.nfsd.server_max_minorversion4 have been added that allow
267 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
269 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
273 armv5 support has been removed from FreeBSD.
276 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
279 sqlite3 is updated to sqlite3-3.30.1.
282 cron(8) now supports the -n (suppress mail on succesful run) and -q
283 (suppress logging of command execution) options in the crontab format.
284 See the crontab(5) manpage for details.
287 ntpd is no longer by default locked in memory. rlimit memlock 32
288 or rlimit memlock 0 can be used to restore this behaviour.
291 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
292 environment variables set by a user via ${name}_env were ignored
293 if the service defined a custom *_cmd variable to control the behavior
294 of the run_rc_command function, e.g., start_cmd, instead of relying on
295 the variables like command and command_args,
297 r351770,r352920,r352922,r352923:
298 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
299 and iflag=fullblock flags, compatible with illumos and GNU.
302 Add kernel-side support for in-kernel Transport Layer Security
303 (KTLS). KTLS permits using sendfile(2) over sockets using
307 WPA is updated from 2.8 to 2.9.
310 Add probes for lockmgr(9) to the lockstat DTrace provider, add
311 corresponding lockstat(1) events, and document the new probes in
315 Intel RST is a new 'feature' that remaps NVMe devices from
316 their normal location to part of the AHCI bar space. This
317 will eliminate the need to set the BIOS SATA setting from RST
318 to AHCI causing the nvme drive to be erased before FreeBSD
319 will see the nvme drive. FreeBSD will now be able to see the
320 nvme drive now in the default config.
323 Add a vop_stdioctl() call, so that file systems that do not support
324 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
325 The algorithm appears to be compatible with the POSIX draft and
326 the implementation in Linux for the case of a file system that
327 does not support holes. Prior to this patch, lseek(2) would reply
328 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
329 file systems that do not support holes.
330 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
331 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
334 The fuse driver has been renamed to fusefs(5) and been substantially
335 rewritten. The new driver includes many bug fixes and performance
336 enhancements, as well as the following user-visible features:
337 * Optional kernel-side permissions checks (-o default_permissions)
338 * mknod(2), socket(2), and pipe(2) support
339 * server side locking with fcntl(2)
340 * FUSE operations are now interruptible when mounted with -o intr
341 * server side handling of UTIME_NOW during utimensat(2)
342 * mount options may be updated with "mount -u"
343 * fusefs file system may now be exported over NFS
344 * RLIMIT_FSIZE support
345 * support for fuse file systems using protocols as old as 7.4
347 FUSE file system developers should also take note of the following new
349 * The protocol level has been raised from 7.8 to 7.23
350 * kqueue support on /dev/fuse
351 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
354 gnop(8) can now configure a delay to be applied to read and write
355 request delays. See the -d, -q and -x parameters.
358 Adds a Linux compatible copy_file_range(2) syscall.
361 libcap_random(3) has been removed. Applications can use native
362 APIs to get random data in capability mode.
365 Add support for using unmapped mbufs with sendfile(2).
368 nand(4) and related components have been removed.
371 The UEFI loader now supports HTTP boot.
374 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
375 guests to play to and record audio data from the host.
378 swapon(8) can now erase a swap device immediately before enabling it,
379 similar to newfs(8)'s -E option. This behaviour can be specified by
380 adding -E to swapon(8)'s command-line parameters, or by adding the
381 "trimonce" option to a swap device's /etc/fstab entry.
384 The following network drivers have been removed: bm(4), cs(4), de(4),
385 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
389 Wired page accounting has been split into kernel wirings and user
390 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
391 the global limit, which is renamed to vm.max_user_wired. bhyve -S
392 allocates user-wired memory and is now subject to that limit.
