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