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 a new "syskrb5" mount option for Kerberized NFSv4.1/4.2 mounts.
15 Without this patch, a Kerberized NFSv4.1/4.2 mount must provide
16 a Kerberos credential for the client at mount time.
17 This patch uses a feature of NFSv4.1/4.2 called SP4_NONE, which
18 allows the state maintenance operations to be performed by any
19 authentication mechanism, so that these operations may be done via
20 AUTH_SYS instead of RPCSEC_GSS (KerberosV). As such, no Kerberos
21 credential is required at mount time.
24 b4805d577787 and many others:
25 Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8)
26 and rpc.tlsservd(8) can be run in an appropriately configured
27 vnet prison. The vnet prison must be on its own file system,
28 have the "allow.nfsd" jail parameter set on it and enforce_statfs
29 cannot be set to "0". Use of UDP and pNFS server configurations
30 are not permitted. (ie. The nfsd command line options "-u", "-p"
31 and "-m" are not supported.)
32 See jail(8), nfsd(8) and mountd(8).
34 68e86d5265bc,e58dfd0de589,59f5a5cb724e,6e272a78de36,4c4a4fd4a649,ba2ae2cca63a:
35 sendmail has been updated to the latest upstream version (8.17.1).
37 225443828ec6..c44d097dcf92:
38 bhyve now supports more than 16 vCPUs in a guest. By default
39 bhyve permits each guest to create the same number of vCPUs as
40 the count of physical CPUs on the host. This limit can be
41 adjusted via the loader tunable hw.vmm.maxcpu.
44 Kernel TLS offload now supports receive-side offload of TLS 1.3.
47 Change handling of the lowest address on an IPv4 (sub)net so that
48 packets are not sent as a broadcast unless this has been set as the
49 broadcast address. This makes the lowest address usable for a host.
50 The old behavior can be restored with the net.inet.ip.broadcast_lowest
51 sysctl. For more information, see
52 https://datatracker.ietf.org/doc/draft-schoen-intarea-lowest-address/.
54 33ff39796ffe,8719e8a951b7:
55 A new rc(8) service script zfskeys allows for automatic decryption
56 of ZFS datasets encrypted with ZFS native encryption during boot.
57 See the rc.conf(5) manual page for more information.
59 b7a2cf0d9102 - eae02d959363:
60 Upgrade bhyve's emulation to version 1.4 of the NVMe specification
62 0a6760a1de32, 3f3676a71266, 580c04df4db6:
66 Add support for the HiFive Unmatched RISC-V board.
69 Add a sysctl called vfs.nfsd.srvmaxio that can be used to
70 increase the NFS server's maximum I/O size from 128Kbytes
71 to any power of 2 up to 1Mbyte. It can only be set when
72 the nfsd threads are not running and will normally require
73 an increase in kern.ipc.maxsockbuf to at least the value
74 recommended by the console log message generated when
75 setting vfs.nfsd.srvmaxio is first attempted.
78 Add a new NFSv4.1/4.2 mount option "nconnect" that can
79 be used to specify the number of TCP connections that
80 will be used for the mount, up to a maximum of 16.
81 The first (default) TCP connection will be used for
82 all RPCs that consist of small RPC messages.
83 The RPCs that can consist of large RPC messages
84 (Read/Readdir/ReaddirPlus/Write) will be sent on the
85 additional TCP connections in a round robin fashion.
86 If either the NFS client or NFS server have multiple
87 network interfaces aggregated together or a network
88 interface that uses multiple queues, this can increase
89 NFS performance for the mount.
92 One True Awk has been updated to the latest from upstream
93 (20210215). All the FreeBSD patches, but one, have now been
94 either up streamed or discarded. Notable changes include:
95 o Locale is no longer used for ranges
97 o Better compatibility with gawk and mawk
99 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
100 we still allow hex numbers, prefixed with 0x, to be parsed and
101 interpreted as hex numbers while all other awks (including one
102 true awk now) interpret them as 0 in line with awk's historic
106 Change the default minor version used for an NFSv4 mount
107 to the highest minor version supported by the NFSv4 server.
108 This default can be overridden by using the "minorversion"
111 2c76eebca71b, 59f6f5e23c1a:
112 Add two daemons rpc.tlsclntd(8) and rpc.tlsservd(8) that provide
113 support for NFS-over-TLS as described in the Internet Draft titled
114 "Towards Remote Procedure Call Encryption By Default".
115 These daemons are only built when WITH_OPENSSL_KTLS is specified
116 and are only tested on amd64 at this time.
117 They use KTLS to encrypt/decrypt all NFS RPC message traffic, plus
118 optional verification of machine identity via X.509 certificates.
121 Add AES-GCM support to armv8crypto(4) providing accelerated
122 support for KTLS, IPsec, and other crypto API consumers.
125 The aesni(4) and armv8crypto(4) devices are now included in
126 GENERIC on amd64, i386, and arm64.
129 Add support for enforcing W^X mapping policy for user
130 processes. The policy is not enforced by default but can be
131 enabled by setting the kern.elf32.allow_wx and
132 kern.elf64.allow_wx sysctls to 0. Individual binaries can be
133 exempted from the policy by elfctl(1) via the wxneeded
137 Add AES-XTS support to armv8crypto(4) providing accelerated
138 software support for the default GELI cipher on arm64 systems.
141 Add aio_writev(2) and aio_readv(2), vectored analogues of aio_write(2)
145 The fusefs(5) protocol has been updated to 7.28. Support for
146 FUSE_COPY_FILE_RANGE and FUSE_LSEEK is added.
149 GDB 6.1.1 was removed. Users of crashinfo(8) should install the
150 gdb package or devel/gdb port.
153 The hme(4) driver was removed.
156 Fixes the case where gssd will not startup because /usr is a separate
157 local file system that is not yet mounted. It does not fix the case
158 where /usr is a separately mounted remote file system (such as NFS).
159 This latter case can be fixed by adding mountcritremote to the
160 REQUIRED line. Unfortunately doing so implies that all Kerberized
161 NFS mounts in /etc/fstab will need the "late" mount option.
162 This was not done, since the requirement for "late" would introduce
166 This commit added a new startup scripts variable called
167 nfsv4_server_only which uses the -R option on mountd added by r367026.
168 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
169 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
170 does not need to be running. Useful for sites which consider rpcbind a
174 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
175 was split out from amd64 DMAR support and is now generic, i.e., it can
176 be used by all architectures.
179 A series of commits ending with r364896 added NFS over TLS
180 to the kernel. This is believed to be compatible with
181 the Internet Draft titled "Towards Remote Procedure Call Encryption
182 By Default" (expected to soon become an RFC).
183 The mount_nfs(8) and exports(5) man pages describe the mount and
184 export option(s) related to NFS over TLS.
185 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
186 { server } must be running on a kernel built with "options KERN_TLS"
187 on an architecture where PMAP_HAS_DMAP != 0.
190 Changes to one obscure devd event generated on resume need to
191 be documented. The old form will still be generated in 13, but not
195 Applications using regex(3), e.g. sed/grep, will no longer accept
196 redundant escapes for most ordinary characters.
199 SCTP support has been removed from GENERIC kernel configurations.
200 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
203 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
206 The safexcel(4) crypto offload driver has been added.
209 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
212 A new implementation of bc and dc has been imported. It offers
213 better standards compliance, performance, localization and comes
214 with extensive test cases that are optionally installed.
215 Use WITHOUT_GH_BC=yes to build and install the world with the
216 previous version instead of the new one, if required.
219 struct export_args has changed so that the "user" specified for
220 the -maproot and -mapall exports(5) options may be in more than
224 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
225 right thing with them, removing the need for printf magic or obnoxious
226 escaping in many scenarios.
228 r361238, r361798, r361799:
229 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
230 Additionally, read(2) of a directory is now rejected with EISDIR by
231 default and may be re-enabled for non-ZFS filesystems that allow it with
232 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
234 Aliases for grep to default to '-d skip' may be desired if commonly
235 non-recursively grepping a list that includes directories and the
236 possibility of EISDIR errors in stderr is not tolerable. Example
237 aliases, commented out, have been installed in /root/.cshrc and
241 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
242 exec.prepare runs before mounts, so can be used to populate new jails.
243 exec.release runs after unmounts, so can be used to remove ephemeral
246 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
247 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
248 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
249 the kernel open cryptographic framework (OCF).
252 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
253 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
256 Remove support for DES, Triple DES, Blowfish, Cast, and
257 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
258 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
261 Remove support for Triple DES, Blowfish, and MD5 HMAC from
265 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
272 init(8), service(8), and cron(8) will now adopt user/class environment
273 variables (excluding PATH, by default, which will be overwritten) by
274 default. Notably, environment variables for all cron jobs and rc
275 services can now be set via login.conf(5).
278 sparc64 has been removed from FreeBSD.
281 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
282 (RFC-8276) to the NFS client and server.
283 NFSv4.2 is comprised of several optional features that can be supported
284 in addition to NFSv4.1. This patch adds the following optional features:
285 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
287 - intra server file range copying via the copy_file_range(2) syscall
288 --> Avoiding data tranfer over the wire to/from the NFS client.
289 - lseek(SEEK_DATA/SEEK_HOLE)
290 - Extended attribute syscalls for "user" namespace attributes as defined
293 For the client, NFSv4.2 is only used if the mount command line option
294 minorversion=2 is specified.
295 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
296 and vfs.nfsd.server_max_minorversion4 have been added that allow
297 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
299 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
303 armv5 support has been removed from FreeBSD.
306 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
309 sqlite3 is updated to sqlite3-3.30.1.
312 cron(8) now supports the -n (suppress mail on succesful run) and -q
313 (suppress logging of command execution) options in the crontab format.
314 See the crontab(5) manpage for details.
317 ntpd is no longer by default locked in memory. rlimit memlock 32
318 or rlimit memlock 0 can be used to restore this behaviour.
321 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
322 environment variables set by a user via ${name}_env were ignored
323 if the service defined a custom *_cmd variable to control the behavior
324 of the run_rc_command function, e.g., start_cmd, instead of relying on
325 the variables like command and command_args,
327 r351770,r352920,r352922,r352923:
328 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
329 and iflag=fullblock flags, compatible with illumos and GNU.
332 Add kernel-side support for in-kernel Transport Layer Security
333 (KTLS). KTLS permits using sendfile(2) over sockets using
337 WPA is updated from 2.8 to 2.9.
340 Add probes for lockmgr(9) to the lockstat DTrace provider, add
341 corresponding lockstat(1) events, and document the new probes in
345 Intel RST is a new 'feature' that remaps NVMe devices from
346 their normal location to part of the AHCI bar space. This
347 will eliminate the need to set the BIOS SATA setting from RST
348 to AHCI causing the nvme drive to be erased before FreeBSD
349 will see the nvme drive. FreeBSD will now be able to see the
350 nvme drive now in the default config.
353 Add a vop_stdioctl() call, so that file systems that do not support
354 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
355 The algorithm appears to be compatible with the POSIX draft and
356 the implementation in Linux for the case of a file system that
357 does not support holes. Prior to this patch, lseek(2) would reply
358 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
359 file systems that do not support holes.
360 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
361 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
364 The fuse driver has been renamed to fusefs(5) and been substantially
365 rewritten. The new driver includes many bug fixes and performance
366 enhancements, as well as the following user-visible features:
367 * Optional kernel-side permissions checks (-o default_permissions)
368 * mknod(2), socket(2), and pipe(2) support
369 * server side locking with fcntl(2)
370 * FUSE operations are now interruptible when mounted with -o intr
371 * server side handling of UTIME_NOW during utimensat(2)
372 * mount options may be updated with "mount -u"
373 * fusefs file system may now be exported over NFS
374 * RLIMIT_FSIZE support
375 * support for fuse file systems using protocols as old as 7.4
377 FUSE file system developers should also take note of the following new
379 * The protocol level has been raised from 7.8 to 7.23
380 * kqueue support on /dev/fuse
381 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
384 gnop(8) can now configure a delay to be applied to read and write
385 request delays. See the -d, -q and -x parameters.
388 Adds a Linux compatible copy_file_range(2) syscall.
391 libcap_random(3) has been removed. Applications can use native
392 APIs to get random data in capability mode.
395 Add support for using unmapped mbufs with sendfile(2).
398 nand(4) and related components have been removed.
401 The UEFI loader now supports HTTP boot.
404 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
405 guests to play to and record audio data from the host.
408 swapon(8) can now erase a swap device immediately before enabling it,
409 similar to newfs(8)'s -E option. This behaviour can be specified by
410 adding -E to swapon(8)'s command-line parameters, or by adding the
411 "trimonce" option to a swap device's /etc/fstab entry.
414 The following network drivers have been removed: bm(4), cs(4), de(4),
415 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
419 Wired page accounting has been split into kernel wirings and user
420 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
421 the global limit, which is renamed to vm.max_user_wired. bhyve -S
422 allocates user-wired memory and is now subject to that limit.
