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 The hme(4) driver was removed.
17 Fixes the case where gssd will not startup because /usr is a separate
18 local file system that is not yet mounted. It does not fix the case
19 where /usr is a separately mounted remote file system (such as NFS).
20 This latter case can be fixed by adding mountcritremote to the
21 REQUIRED line. Unfortunately doing so implies that all Kerberized
22 NFS mounts in /etc/fstab will need the "late" mount option.
23 This was not done, since the requirement for "late" would introduce
27 This commit added a new startup scripts variable called
28 nfsv4_server_only which uses the -R option on mountd added by r367026.
29 When nfsv4_server_only is set to "YES" in /etc/rc.conf, the NFS server
30 only handles NFSv4 and does not register with rpcbind. As such, rpcbind
31 does not need to be running. Useful for sites which consider rpcbind a
35 Kernel option ACPI_DMAR was renamed to IOMMU. amd64's IOMMU subsystem
36 was split out from amd64 DMAR support and is now generic, i.e., it can
37 be used by all architectures.
40 A series of commits ending with r364896 added NFS over TLS
41 to the kernel. This is believed to be compatible with
42 the Internet Draft titled "Towards Remote Procedure Call Encryption
43 By Default" (expected to soon become an RFC).
44 The mount_nfs(8) and exports(5) man pages describe the mount and
45 export option(s) related to NFS over TLS.
46 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
47 { server } must be running on a kernel built with "options KERN_TLS"
48 on an architecture where PMAP_HAS_DMAP != 0.
51 Changes to one obscure devd event generated on resume need to
52 be documented. The old form will still be generated in 13, but not
56 Applications using regex(3), e.g. sed/grep, will no longer accept
57 redundant escapes for most ordinary characters.
60 SCTP support has been removed from GENERIC kernel configurations.
61 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
64 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
67 The safexcel(4) crypto offload driver has been added.
70 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
73 A new implementation of bc and dc has been imported. It offers
74 better standards compliance, performance, localization and comes
75 with extensive test cases that are optionally installed.
76 Use WITHOUT_GH_BC=yes to build and install the world with the
77 previous version instead of the new one, if required.
80 struct export_args has changed so that the "user" specified for
81 the -maproot and -mapall exports(5) options may be in more than
85 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
86 right thing with them, removing the need for printf magic or obnoxious
87 escaping in many scenarios.
89 r361238, r361798, r361799:
90 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
91 Additionally, read(2) of a directory is now rejected with EISDIR by
92 default and may be re-enabled for non-ZFS filesystems that allow it with
93 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
95 Aliases for grep to default to '-d skip' may be desired if commonly
96 non-recursively grepping a list that includes directories and the
97 possibility of EISDIR errors in stderr is not tolerable. Example
98 aliases, commented out, have been installed in /root/.cshrc and
102 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
103 exec.prepare runs before mounts, so can be used to populate new jails.
104 exec.release runs after unmounts, so can be used to remove ephemeral
107 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
108 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
109 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
110 the kernel open cryptographic framework (OCF).
113 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
114 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
117 Remove support for DES, Triple DES, Blowfish, Cast, and
118 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
119 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
122 Remove support for Triple DES, Blowfish, and MD5 HMAC from
126 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
133 init(8), service(8), and cron(8) will now adopt user/class environment
134 variables (excluding PATH, by default, which will be overwritten) by
135 default. Notably, environment variables for all cron jobs and rc
136 services can now be set via login.conf(5).
139 sparc64 has been removed from FreeBSD.
142 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
143 (RFC-8276) to the NFS client and server.
144 NFSv4.2 is comprised of several optional features that can be supported
145 in addition to NFSv4.1. This patch adds the following optional features:
146 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
148 - intra server file range copying via the copy_file_range(2) syscall
149 --> Avoiding data tranfer over the wire to/from the NFS client.
150 - lseek(SEEK_DATA/SEEK_HOLE)
151 - Extended attribute syscalls for "user" namespace attributes as defined
154 For the client, NFSv4.2 is only used if the mount command line option
155 minorversion=2 is specified.
156 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
157 and vfs.nfsd.server_max_minorversion4 have been added that allow
158 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
160 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
164 armv5 support has been removed from FreeBSD.
167 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
170 sqlite3 is updated to sqlite3-3.30.1.
173 cron(8) now supports the -n (suppress mail on succesful run) and -q
174 (suppress logging of command execution) options in the crontab format.
175 See the crontab(5) manpage for details.
178 ntpd is no longer by default locked in memory. rlimit memlock 32
179 or rlimit memlock 0 can be used to restore this behaviour.
182 rc.subr(8) now honors ${name}_env in all rc(8) scripts. Previously,
183 environment variables set by a user via ${name}_env were ignored
184 if the service defined a custom *_cmd variable to control the behavior
185 of the run_rc_command function, e.g., start_cmd, instead of relying on
186 the variables like command and command_args,
188 r351770,r352920,r352922,r352923:
189 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
190 and iflag=fullblock flags, compatible with illumos and GNU.
193 Add kernel-side support for in-kernel Transport Layer Security
194 (KTLS). KTLS permits using sendfile(2) over sockets using
198 WPA is updated from 2.8 to 2.9.
201 Add probes for lockmgr(9) to the lockstat DTrace provider, add
202 corresponding lockstat(1) events, and document the new probes in
206 Intel RST is a new 'feature' that remaps NVMe devices from
207 their normal location to part of the AHCI bar space. This
208 will eliminate the need to set the BIOS SATA setting from RST
209 to AHCI causing the nvme drive to be erased before FreeBSD
210 will see the nvme drive. FreeBSD will now be able to see the
211 nvme drive now in the default config.
214 Add a vop_stdioctl() call, so that file systems that do not support
215 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
216 The algorithm appears to be compatible with the POSIX draft and
217 the implementation in Linux for the case of a file system that
218 does not support holes. Prior to this patch, lseek(2) would reply
219 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
220 file systems that do not support holes.
221 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
222 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
225 The fuse driver has been renamed to fusefs(5) and been substantially
226 rewritten. The new driver includes many bug fixes and performance
227 enhancements, as well as the following user-visible features:
228 * Optional kernel-side permissions checks (-o default_permissions)
229 * mknod(2), socket(2), and pipe(2) support
230 * server side locking with fcntl(2)
231 * FUSE operations are now interruptible when mounted with -o intr
232 * server side handling of UTIME_NOW during utimensat(2)
233 * mount options may be updated with "mount -u"
234 * fusefs file system may now be exported over NFS
235 * RLIMIT_FSIZE support
236 * support for fuse file systems using protocols as old as 7.4
238 FUSE file system developers should also take note of the following new
240 * The protocol level has been raised from 7.8 to 7.23
241 * kqueue support on /dev/fuse
242 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
245 gnop(8) can now configure a delay to be applied to read and write
246 request delays. See the -d, -q and -x parameters.
249 Adds a Linux compatible copy_file_range(2) syscall.
252 libcap_random(3) has been removed. Applications can use native
253 APIs to get random data in capability mode.
256 Add support for using unmapped mbufs with sendfile(2).
259 nand(4) and related components have been removed.
262 The UEFI loader now supports HTTP boot.
265 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
266 guests to play to and record audio data from the host.
269 swapon(8) can now erase a swap device immediately before enabling it,
270 similar to newfs(8)'s -E option. This behaviour can be specified by
271 adding -E to swapon(8)'s command-line parameters, or by adding the
272 "trimonce" option to a swap device's /etc/fstab entry.
275 The following network drivers have been removed: bm(4), cs(4), de(4),
276 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
280 Wired page accounting has been split into kernel wirings and user
281 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
282 the global limit, which is renamed to vm.max_user_wired. bhyve -S
283 allocates user-wired memory and is now subject to that limit.
