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 A series of commits ending with r364896 added NFS over TLS
15 to the kernel. This is believed to be compatible with
16 the Internet Draft titled "Towards Remote Procedure Call Encryption
17 By Default" (expected to soon become an RFC).
18 The mount_nfs(8) and exports(5) man pages describe the mount and
19 export option(s) related to NFS over TLS.
20 For NFS over TLS to work, the rpctlscd(8) { client } or rpctlssd(8)
21 { server } must be running on a kernel built with "options KERN_TLS"
22 on an architecture where PMAP_HAS_DMAP != 0.
25 Changes to one obscure devd event generated on resume need to
26 be documented. The old form will still be generated in 13, but not
30 Applications using regex(3), e.g. sed/grep, will no longer accept
31 redundant escapes for most ordinary characters.
34 SCTP support has been removed from GENERIC kernel configurations.
35 The SCTP stack is now built as sctp.ko and can be dynamically loaded.
38 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
41 The safexcel(4) crypto offload driver has been added.
44 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
47 A new implementation of bc and dc has been imported. It offers
48 better standards compliance, performance, localization and comes
49 with extensive test cases that are optionally installed.
50 Use WITHOUT_GH_BC=yes to build and install the world with the
51 previous version instead of the new one, if required.
54 struct export_args has changed so that the "user" specified for
55 the -maproot and -mapall exports(5) options may be in more than
59 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
60 right thing with them, removing the need for printf magic or obnoxious
61 escaping in many scenarios.
63 r361238, r361798, r361799:
64 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
65 Additionally, read(2) of a directory is now rejected with EISDIR by
66 default and may be re-enabled for non-ZFS filesystems that allow it with
67 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
69 Aliases for grep to default to '-d skip' may be desired if commonly
70 non-recursively grepping a list that includes directories and the
71 possibility of EISDIR errors in stderr is not tolerable. Example
72 aliases, commented out, have been installed in /root/.cshrc and
76 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
77 exec.prepare runs before mounts, so can be used to populate new jails.
78 exec.release runs after unmounts, so can be used to remove ephemeral
81 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
82 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
83 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
84 the kernel open cryptographic framework (OCF).
87 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
88 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
91 Remove support for DES, Triple DES, Blowfish, Cast, and
92 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
93 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
96 Remove support for Triple DES, Blowfish, and MD5 HMAC from
100 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
107 init(8), service(8), and cron(8) will now adopt user/class environment
108 variables (excluding PATH, by default, which will be overwritten) by
109 default. Notably, environment variables for all cron jobs and rc
110 services can now be set via login.conf(5).
113 sparc64 has been removed from FreeBSD.
116 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
117 (RFC-8276) to the NFS client and server.
118 NFSv4.2 is comprised of several optional features that can be supported
119 in addition to NFSv4.1. This patch adds the following optional features:
120 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
122 - intra server file range copying via the copy_file_range(2) syscall
123 --> Avoiding data tranfer over the wire to/from the NFS client.
124 - lseek(SEEK_DATA/SEEK_HOLE)
125 - Extended attribute syscalls for "user" namespace attributes as defined
128 For the client, NFSv4.2 is only used if the mount command line option
129 minorversion=2 is specified.
130 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
131 and vfs.nfsd.server_max_minorversion4 have been added that allow
132 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
134 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
138 armv5 support has been removed from FreeBSD.
141 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
144 sqlite3 is updated to sqlite3-3.30.1.
147 cron(8) now supports the -n (suppress mail on succesful run) and -q
148 (suppress logging of command execution) options in the crontab format.
149 See the crontab(5) manpage for details.
152 ntpd is no longer by default locked in memory. rlimit memlock 32
153 or rlimit memlock 0 can be used to restore this behaviour.
155 r351770,r352920,r352922,r352923:
156 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
157 and iflag=fullblock flags, compatible with illumos and GNU.
160 Add kernel-side support for in-kernel Transport Layer Security
161 (KTLS). KTLS permits using sendfile(2) over sockets using
165 WPA is updated from 2.8 to 2.9.
168 Add probes for lockmgr(9) to the lockstat DTrace provider, add
169 corresponding lockstat(1) events, and document the new probes in
173 Intel RST is a new 'feature' that remaps NVMe devices from
174 their normal location to part of the AHCI bar space. This
175 will eliminate the need to set the BIOS SATA setting from RST
176 to AHCI causing the nvme drive to be erased before FreeBSD
177 will see the nvme drive. FreeBSD will now be able to see the
178 nvme drive now in the default config.
181 Add a vop_stdioctl() call, so that file systems that do not support
182 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
183 The algorithm appears to be compatible with the POSIX draft and
184 the implementation in Linux for the case of a file system that
185 does not support holes. Prior to this patch, lseek(2) would reply
186 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
187 file systems that do not support holes.
188 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
189 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
192 The fuse driver has been renamed to fusefs(5) and been substantially
193 rewritten. The new driver includes many bug fixes and performance
194 enhancements, as well as the following user-visible features:
195 * Optional kernel-side permissions checks (-o default_permissions)
196 * mknod(2), socket(2), and pipe(2) support
197 * server side locking with fcntl(2)
198 * FUSE operations are now interruptible when mounted with -o intr
199 * server side handling of UTIME_NOW during utimensat(2)
200 * mount options may be updated with "mount -u"
201 * fusefs file system may now be exported over NFS
202 * RLIMIT_FSIZE support
203 * support for fuse file systems using protocols as old as 7.4
205 FUSE file system developers should also take note of the following new
207 * The protocol level has been raised from 7.8 to 7.23
208 * kqueue support on /dev/fuse
209 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
212 gnop(8) can now configure a delay to be applied to read and write
213 request delays. See the -d, -q and -x parameters.
216 Adds a Linux compatible copy_file_range(2) syscall.
219 libcap_random(3) has been removed. Applications can use native
220 APIs to get random data in capability mode.
223 Add support for using unmapped mbufs with sendfile(2).
226 nand(4) and related components have been removed.
229 The UEFI loader now supports HTTP boot.
232 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
233 guests to play to and record audio data from the host.
236 swapon(8) can now erase a swap device immediately before enabling it,
237 similar to newfs(8)'s -E option. This behaviour can be specified by
238 adding -E to swapon(8)'s command-line parameters, or by adding the
239 "trimonce" option to a swap device's /etc/fstab entry.
242 The following network drivers have been removed: bm(4), cs(4), de(4),
243 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
247 Wired page accounting has been split into kernel wirings and user
248 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
249 the global limit, which is renamed to vm.max_user_wired. bhyve -S
250 allocates user-wired memory and is now subject to that limit.
