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 Remove support for DES, Triple DES, and RC4 from in-kernel GSS
21 init(8), service(8), and cron(8) will now adopt user/class environment
22 variables (excluding PATH, by default, which will be overwritten) by
23 default. Notably, environment variables for all cron jobs and rc
24 services can now be set via login.conf(5).
27 sparc64 has been removed from FreeBSD.
30 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
31 (RFC-8276) to the NFS client and server.
32 NFSv4.2 is comprised of several optional features that can be supported
33 in addition to NFSv4.1. This patch adds the following optional features:
34 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
36 - intra server file range copying via the copy_file_range(2) syscall
37 --> Avoiding data tranfer over the wire to/from the NFS client.
38 - lseek(SEEK_DATA/SEEK_HOLE)
39 - Extended attribute syscalls for "user" namespace attributes as defined
42 For the client, NFSv4.2 is only used if the mount command line option
43 minorversion=2 is specified.
44 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
45 and vfs.nfsd.server_max_minorversion4 have been added that allow
46 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
48 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
52 armv5 support has been removed from FreeBSD.
55 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
58 sqlite3 is updated to sqlite3-3.30.1.
61 cron(8) now supports the -n (suppress mail on succesful run) and -q
62 (suppress logging of command execution) options in the crontab format.
63 See the crontab(5) manpage for details.
66 ntpd is no longer by default locked in memory. rlimit memlock 32
67 or rlimit memlock 0 can be used to restore this behaviour.
70 Add kernel-side support for in-kernel Transport Layer Security
71 (KTLS). KTLS permits using sendfile(2) over sockets using
75 WPA is updated from 2.8 to 2.9.
78 Add probes for lockmgr(9) to the lockstat DTrace provider, add
79 corresponding lockstat(1) events, and document the new probes in
83 Intel RST is a new 'feature' that remaps NVMe devices from
84 their normal location to part of the AHCI bar space. This
85 will eliminate the need to set the BIOS SATA setting from RST
86 to AHCI causing the nvme drive to be erased before FreeBSD
87 will see the nvme drive. FreeBSD will now be able to see the
88 nvme drive now in the default config.
91 Add a vop_stdioctl() call, so that file systems that do not support
92 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
93 The algorithm appears to be compatible with the POSIX draft and
94 the implementation in Linux for the case of a file system that
95 does not support holes. Prior to this patch, lseek(2) would reply
96 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
97 file systems that do not support holes.
98 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
99 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
102 The fuse driver has been renamed to fusefs(5) and been substantially
103 rewritten. The new driver includes many bug fixes and performance
104 enhancements, as well as the following user-visible features:
105 * Optional kernel-side permissions checks (-o default_permissions)
106 * mknod(2), socket(2), and pipe(2) support
107 * server side locking with fcntl(2)
108 * FUSE operations are now interruptible when mounted with -o intr
109 * server side handling of UTIME_NOW during utimensat(2)
110 * mount options may be updated with "mount -u"
111 * fusefs file system may now be exported over NFS
112 * RLIMIT_FSIZE support
113 * support for fuse file systems using protocols as old as 7.4
115 FUSE file system developers should also take note of the following new
117 * The protocol level has been raised from 7.8 to 7.23
118 * kqueue support on /dev/fuse
119 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
122 gnop(8) can now configure a delay to be applied to read and write
123 request delays. See the -d, -q and -x parameters.
126 Adds a Linux compatible copy_file_range(2) syscall.
129 libcap_random(3) has been removed. Applications can use native
130 APIs to get random data in capability mode.
133 Add support for using unmapped mbufs with sendfile(2).
136 nand(4) and related components have been removed.
139 The UEFI loader now supports HTTP boot.
142 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
143 guests to play to and record audio data from the host.
146 swapon(8) can now erase a swap device immediately before enabling it,
147 similar to newfs(8)'s -E option. This behaviour can be specified by
148 adding -E to swapon(8)'s command-line parameters, or by adding the
149 "trimonce" option to a swap device's /etc/fstab entry.
152 The following network drivers have been removed: bm(4), cs(4), de(4),
153 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
