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 Merge sendmail 8.16.1: See contrib/sendmail/RELEASE_NOTES for details.
17 The safexcel(4) crypto offload driver has been added.
20 nc(1) now implements SCTP mode, enabled by specifying the --sctp option.
23 struct export_args has changed so that the "user" specified for
24 the -maproot and -mapall exports(5) options may be in more than
28 sed(1) has learned about hex escapes (e.g. \x27) and will now do the
29 right thing with them, removing the need for printf magic or obnoxious
30 escaping in many scenarios.
32 r361238, r361798, r361799:
33 ZFS will now unconditionally reject read(2) of a directory with EISDIR.
34 Additionally, read(2) of a directory is now rejected with EISDIR by
35 default and may be re-enabled for non-ZFS filesystems that allow it with
36 the sysctl(8) MIB 'security.bsd.allow_read_dir'.
38 Aliases for grep to default to '-d skip' may be desired if commonly
39 non-recursively grepping a list that includes directories and the
40 possibility of EISDIR errors in stderr is not tolerable. Example
41 aliases, commented out, have been installed in /root/.cshrc and
45 Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
46 exec.prepare runs before mounts, so can be used to populate new jails.
47 exec.release runs after unmounts, so can be used to remove ephemeral
50 r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
51 Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
52 MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
53 the kernel open cryptographic framework (OCF).
56 Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
57 MD5-HMAC, and Skipjack algorithms from /dev/crypto.
60 Remove support for DES, Triple DES, Blowfish, Cast, and
61 Camellia ciphers from IPsec(4). Remove support for MD5-HMAC,
62 Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
65 Remove support for Triple DES, Blowfish, and MD5 HMAC from
69 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
76 init(8), service(8), and cron(8) will now adopt user/class environment
77 variables (excluding PATH, by default, which will be overwritten) by
78 default. Notably, environment variables for all cron jobs and rc
79 services can now be set via login.conf(5).
82 sparc64 has been removed from FreeBSD.
85 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
86 (RFC-8276) to the NFS client and server.
87 NFSv4.2 is comprised of several optional features that can be supported
88 in addition to NFSv4.1. This patch adds the following optional features:
89 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
91 - intra server file range copying via the copy_file_range(2) syscall
92 --> Avoiding data tranfer over the wire to/from the NFS client.
93 - lseek(SEEK_DATA/SEEK_HOLE)
94 - Extended attribute syscalls for "user" namespace attributes as defined
97 For the client, NFSv4.2 is only used if the mount command line option
98 minorversion=2 is specified.
99 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
100 and vfs.nfsd.server_max_minorversion4 have been added that allow
101 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
103 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
107 armv5 support has been removed from FreeBSD.
110 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
113 sqlite3 is updated to sqlite3-3.30.1.
116 cron(8) now supports the -n (suppress mail on succesful run) and -q
117 (suppress logging of command execution) options in the crontab format.
118 See the crontab(5) manpage for details.
121 ntpd is no longer by default locked in memory. rlimit memlock 32
122 or rlimit memlock 0 can be used to restore this behaviour.
124 r351770,r352920,r352922,r352923:
125 dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
126 and iflag=fullblock flags, compatible with illumos and GNU.
129 Add kernel-side support for in-kernel Transport Layer Security
130 (KTLS). KTLS permits using sendfile(2) over sockets using
134 WPA is updated from 2.8 to 2.9.
137 Add probes for lockmgr(9) to the lockstat DTrace provider, add
138 corresponding lockstat(1) events, and document the new probes in
142 Intel RST is a new 'feature' that remaps NVMe devices from
143 their normal location to part of the AHCI bar space. This
144 will eliminate the need to set the BIOS SATA setting from RST
145 to AHCI causing the nvme drive to be erased before FreeBSD
146 will see the nvme drive. FreeBSD will now be able to see the
147 nvme drive now in the default config.
150 Add a vop_stdioctl() call, so that file systems that do not support
151 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
152 The algorithm appears to be compatible with the POSIX draft and
153 the implementation in Linux for the case of a file system that
154 does not support holes. Prior to this patch, lseek(2) would reply
155 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
156 file systems that do not support holes.
157 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
158 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
161 The fuse driver has been renamed to fusefs(5) and been substantially
162 rewritten. The new driver includes many bug fixes and performance
163 enhancements, as well as the following user-visible features:
164 * Optional kernel-side permissions checks (-o default_permissions)
165 * mknod(2), socket(2), and pipe(2) support
166 * server side locking with fcntl(2)
167 * FUSE operations are now interruptible when mounted with -o intr
168 * server side handling of UTIME_NOW during utimensat(2)
169 * mount options may be updated with "mount -u"
170 * fusefs file system may now be exported over NFS
171 * RLIMIT_FSIZE support
172 * support for fuse file systems using protocols as old as 7.4
174 FUSE file system developers should also take note of the following new
176 * The protocol level has been raised from 7.8 to 7.23
177 * kqueue support on /dev/fuse
178 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
181 gnop(8) can now configure a delay to be applied to read and write
182 request delays. See the -d, -q and -x parameters.
185 Adds a Linux compatible copy_file_range(2) syscall.
188 libcap_random(3) has been removed. Applications can use native
189 APIs to get random data in capability mode.
192 Add support for using unmapped mbufs with sendfile(2).
195 nand(4) and related components have been removed.
198 The UEFI loader now supports HTTP boot.
201 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
202 guests to play to and record audio data from the host.
205 swapon(8) can now erase a swap device immediately before enabling it,
206 similar to newfs(8)'s -E option. This behaviour can be specified by
207 adding -E to swapon(8)'s command-line parameters, or by adding the
208 "trimonce" option to a swap device's /etc/fstab entry.
211 The following network drivers have been removed: bm(4), cs(4), de(4),
212 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
216 Wired page accounting has been split into kernel wirings and user
217 wirings (e.g., by mlock(2)). Kernel wirings no long count towards
218 the global limit, which is renamed to vm.max_user_wired. bhyve -S
219 allocates user-wired memory and is now subject to that limit.
